("ISP"), to be held on February___, 2003, at _ _.m., local time, at the offices of Simpson Thacher & Bartlett, 425 Lexington Avenue, New York, New York. At the special meeting, you will be asked to consider and vote upon a proposal to adopt the Agreement and Plan of Merger, dated as of November 8, 2002, between ISP and International Specialty Products Holdings Inc. ("ISPH"). Samuel J. Heyman, our Chairman, formed ISPH for purposes of entering into this transaction and is currently the sole "beneficial owner" (as defined in Rule 13d-3 under the Securities Exchange Act of 1934) of all of ISPH's common stock and approximately 81% of ISP's common stock. Under the merger agreement, ISPH will be merged with and into ISP, with ISP as the surviving corporation. Pursuant to the merger, you will be entitled to receive $10.30 per share in cash, without interest, for each share of ISP common stock that you own. This price represents a 30% premium over the closing price per share of $7.95 on July 8, 2002, the last trading day before Mr. Heyman's public proposal to acquire the shares of ISP that he does not already beneficially own. No merger consideration will be paid for shares Mr. Heyman beneficially owns at the time of the merger, except shares held by qualified charitable organizations (which will be entitled to receive the $10.30 per share merger consideration). SINCE YOU WILL ONLY HAVE THE RIGHT TO RECEIVE CASH PURSUANT TO THE MERGER, AFTER THE MERGER OCCURS, YOU WILL NO LONGER BE A STOCKHOLDER OF ISP AND MR. HEYMAN WILL BE THE SOLE BENEFICIAL OWNER OF ISP. Based on the number of our outstanding shares of common stock and options to purchase common stock, the aggregate cash consideration to be paid in connection with the merger is approximately $134.4 million. Details of the merger and the merger agreement are discussed in the accompanying proxy statement. A copy of the merger agreement is attached as Exhibit A to the proxy statement. We encourage you to read the proxy statement and the merger agreement carefully. The receipt of cash in exchange for your shares of common stock in the merger will constitute a taxable transaction for U.S. federal income tax purposes. Please read the accompanying proxy statement carefully regarding the tax consequences of the merger. Our board of directors formed a special committee of independent directors who are not officers or employees of ISP and who are otherwise independent of Mr. Heyman to review and evaluate the merger and the merger agreement. The special committee unanimously recommended to our board of directors that the merger agreement be approved. In connection with its evaluation of the merger, the special committee engaged Lehman Brothers Inc. as its financial advisor. Lehman Brothers has rendered its opinion that, as of the date of that opinion and, based upon and subject to the assumptions, limitations and qualifications set forth in that opinion, the $10.30 per share cash merger consideration is fair, from a financial point of view, to the unaffiliated stockholders of ISP. The written opinion of Lehman Brothers is attached as Annex B to the accompanying proxy statement, and you should read it carefully for a discussion of the assumptions made, procedures followed, factors considered and limitations upon the review undertaken by Lehman Brothers in rendering its opinion. Our board of directors, based on the unanimous recommendation of the special committee, has approved and declared the advisability of the merger agreement. The board of directors and special committee believe that the terms of the merger are fair to, and in the best interests of, ISP's unaffiliated stockholders. Our board of directors recommends that the stockholders of ISP vote "FOR" the adoption of the merger agreement. When you consider the recommendation of our board of directors to adopt the merger agreement, you should be aware that some of our directors and executive officers have interests in the merger that may be different than the interests of our stockholders generally. Your vote is very important. We cannot complete the merger unless the merger agreement is adopted by the affirmative vote of a majority of the outstanding shares of ISP common stock. As of the record date for the special meeting, Mr. Heyman and our directors and officers beneficially owned a total of 54,331,518 shares, which is approximately 83.3% of all outstanding shares. Mr. Heyman has agreed to vote all of the shares of common stock beneficially owned by him at the time of the special meeting (but excluding shares held by qualified charitable organizations) in favor of the merger, and we also expect our directors and executive officers to vote for the transaction. If that occurs, we will have obtained the requisite vote under the General Corporation Law of the State of Delaware. In addition, while not required by the General Corporation Law of the State of Delaware or ISP's amended and restated certificate of incorporation or by-laws, the merger also is conditioned upon the affirmative vote of a majority of shares of common stock voting on the merger at the special meeting that are not owned beneficially or of record by Mr. Heyman or any other officer or director of ISP or ISPH. Please complete and sign the enclosed proxy card and return it as soon as possible in the enclosed postage paid envelope. This will ensure that your shares are represented at the special meeting. Sincerely, /s/ Sunil Kumar --------------- Sunil Kumar PRESIDENT AND CHIEF EXECUTIVE OFFICER This proxy statement is dated February _, 2003, and is first being mailed to stockholders of ISP on or about February _, 2003. -------------------------------------------------------------------------------- THIS TRANSACTION HAS NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION. NEITHER THE SECURITIES AND EXCHANGE COMMISSION NOR ANY STATE SECURITIES COMMISSION HAS PASSED UPON THE FAIRNESS OR MERITS OF THIS TRANSACTION OR UPON THE ACCURACY OR ADEQUACY OF THE INFORMATION CONTAINED IN THIS DOCUMENT. ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE. -------------------------------------------------------------------------------- [LOGO] ISP INTERNATIONAL SPECIALTY PRODUCTS INC. NOTICE OF SPECIAL MEETING OF STOCKHOLDERS A special meeting of stockholders of International Specialty Products Inc. will be held at __ _.m., local time, February ___, 2003 at the offices of Simpson Thacher & Bartlett, 425 Lexington Avenue, New York, New York, for the following purposes: o To vote on a proposal to adopt the Agreement and Plan of Merger, dated as of November 8, 2002, by and between ISP and International Specialty Products Holdings Inc.; and o To consider any other matters that are properly brought before the special meeting or any adjournments or postponements of the special meeting. Our board of directors has fixed the close of business on January 10, 2003 as the record date for the determination of stockholders entitled to notice of, and to vote at, the special meeting and any adjournments or postponements of the special meeting. The accompanying proxy statement forms a part of this notice. We urge you to read it carefully. Under the General Corporation Law of the State of Delaware, holders of our common stock who do not vote in favor of the adoption of the merger agreement will have the right to seek appraisal of the fair value of their shares as determined by the Court of Chancery of the State of Delaware if the merger is completed, but only if they submit a written demand for such an appraisal prior to the vote on the merger agreement and they comply with the other procedures required by the General Corporation Law of the State of Delaware. See "The Merger--Appraisal Rights" in the accompanying proxy statement and Annex D to the proxy statement for more information concerning appraisal rights under Delaware law.

You should carefully read this entire proxy statement and the other documents we refer you to for a more complete understanding of the matters being considered at the special meeting. In addition, we incorporate by reference important business and financial information about International Specialty Products Inc., or ISP, into this proxy statement. You may obtain the information incorporated by reference into this proxy statement without charge by following the instructions in the section entitled "Where You Can Find More Information." THE MERGER (SEE PAGE 37) In the merger, International Specialty Products Holdings Inc., or ISPH, will merge into ISP, with ISP as the surviving corporation in the merger. As a result of the merger, we will cease to be a publicly held company and will become a private corporation. Our Chairman and major stockholder, Samuel J. Heyman, will beneficially own all of our stock after the merger. WHAT YOU WILL BE ENTITLED TO RECEIVE IN THE MERGER (SEE PAGE 38) If we complete the merger, holders of our common stock, other than holders of common stock beneficially owned by Mr. Heyman and other than stockholders that validly exercise appraisal rights under the General Corporation Law of the State of Delaware, or DGCL, will be entitled to receive $10.30 in cash for each share of common stock that they own. Shares beneficially owned by Mr. Heyman, other than 525,000 shares held by a qualified charitable organization, will be canceled in the merger, and the shares of ISPH, all of which are beneficially owned by Mr. heyman, will be converted into shares of ISP in the merger. The 525,000 shares held by the qualified charitable organization are deemed to be beneficially owned by Mr. Heyman because he is a director and the president of the organization. In accordance with the merger agreement, the qualified charitable organization will receive $10.30 in cash for each of these shares. RECOMMENDATIONS OF THE SPECIAL COMMITTEE AND OUR BOARD OF DIRECTORS (SEE PAGE 16) Because Mr. Heyman is our majority stockholder and proposed the merger and because Mr. Heyman and Sunil Kumar, ISP's President and Chief Executive Officer, are both directors of ISP and ISPH, our board of directors established a special committee to consider and evaluate the proposed merger. The special committee consists of three of our directors who are not members of our management or affiliated with Mr. Heyman. After careful consideration, the special committee unanimously: o determined that the merger agreement is advisable, fair to, and in the best interests of, the unaffiliated holders of our common stock, and o recommended to our board of directors that it - approve the merger agreement, - declare its advisability and - recommend that our stockholders vote to adopt the merger agreement. Based on this unanimous recommendation, our board of directors determined the merger agreement to be advisable and the terms and conditions of the merger to be fair to, and in the best interests of, the unaffiliated holders of our common stock, and approved the merger agreement. ACCORDINGLY, OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" THE PROPOSAL TO ADOPT THE MERGER AGREEMENT. For a discussion of the material factors considered by the special committee and our board of directors in reaching their conclusions and the reasons why the special committee and the board of directors determined that the merger is fair, see "Special Factors--Recommendations of the Special Committee" and "Special Factors--Recommendations of our Board of Directors." OPINION OF LEHMAN BROTHERS INC. (SEE PAGE 21) In connection with the merger, the special committee and our board of directors considered the opinion of Lehman Brothers Inc., the special committee's financial advisor. Lehman Brothers delivered its written opinion to the special committee on November 8, 2002 to the effect that, as of that date, the $10.30 per share cash merger consideration is fair, from a financial -------------------------------------------------------------------------------- 1 -------------------------------------------------------------------------------- point of view, to the unaffiliated holders of ISP's common stock. You should be aware, however, that the opinion was based on and subject to important assumptions, limitations and qualifications. The full text of this opinion is attached as Annex B to this proxy statement. We urge you to read that opinion in its entirety for a description of the assumptions made, procedures followed, factors considered and limitations on the review undertaken. OUR POSITION AS TO THE FAIRNESS OF THE MERGER (SEE PAGE 19) We believe the merger is fair to the unaffiliated holders of our common stock. Many facts support this conclusion, including: o the proposed merger would entitle each stockholder of ISP, other than holders of common stock beneficially owned by Mr. Heyman (except 525,000 shares held by a qualified charitable organizations that will be converted into the $10.30 per share cash merger consideration), to the right to receive $10.30 in cash; o the opinion of Lehman Brothers to the effect that, as of the date of the opinion, and based upon and subject to the assumptions, limitations and qualifications set forth in its written opinion, the $10.30 per share cash merger consideration is fair, from a financial view, to the unaffiliated holders of our common stock; o the fact that the terms and conditions of the proposed merger were determined through negotiations between Mr. Heyman and his representatives and the special committee and its advisors, none of whom were affiliated with Mr. Heyman; and o the merger is conditioned upon the affirmative vote of a majority of shares of common stock voting on the merger at the special meeting that are not owned beneficially or of record by Mr. Heyman or any other officer or director of ISP or ISPH. We refer to this approval requirement as the majority of the minority condition. MR. HEYMAN AND ISPH'S POSITION AS TO THE FAIRNESS OF THE MERGER (SEE PAGE 20) Although neither Mr. Heyman nor ISPH has performed, or engaged a financial advisor to perform, any valuation analysis for the purposes of assessing the fairness of the merger to the unaffiliated holders of ISP common stock, both believe that the merger is substantively and procedurally fair to those holders. Mr. Heyman and ISPH believe this conclusion is supported by the factors described above and by other factors, including: o the merger consideration of $10.30 per share represents a 30% premium over our common stock's $7.95 closing price on the New York Stock Exchange on July 8, 2002, the last trading day before Mr. Heyman announced his initial merger proposal, and a 49% premium over the average closing price for the 30 days prior to that announcement; o the S&P 500 Index and the S&P Midcap Specialty Chemicals Index declined 5.5% and 9.3%, respectively, between July 8, 2002 and November 6, 2002 (the date the special committee agreed to recommend the merger agreement), indicating that the premium represented by the $10.30 merger consideration might have been even greater had ISP's common stock performed consistently with the broader market and its industry peers in absence of the pending merger proposal; o the merger was approved and recommended by the special committee and the board of directors; and o stockholders who do not vote in favor of the merger would be entitled, subject to compliance with certain procedures described under "The Merger--Appraisal Rights", to exercise Delaware statutory appraisal rights in the merger, which allow stockholders to have the fair value of their shares determined by the Court of Chancery of the State of Delaware and paid to them in cash. INTERESTS OF DIRECTORS AND EXECUTIVE OFFICERS IN THE MERGER (SEE PAGE 32) In considering the recommendation of our board of directors that ISP's stockholders vote to adopt the merger agreement so that the merger can occur, you should be aware that our executive officers and directors have interests in the merger that may conflict with the interests of our stockholders generally. These interests include: o Mr. Heyman is the Chairman of our board of directors and, as a result of the merger, will increase his beneficial ownership of our common stock from approximately 81% to 100%; o Mr. Heyman and Mr. Kumar are members of both ISP and ISPH's board of directors; -------------------------------------------------------------------------------- 2 -------------------------------------------------------------------------------- o each of ISPH's officers, consisting of Mr. Kumar (President and Chief Executive Officer), Richard A. Weinberg (Executive Vice President, General Counsel and Secretary) and Susan B. Yoss (Executive Vice President--Finance and Treasurer), is also an officer of ISP; o some of our officers and directors will receive cash payments in connection with the merger in exchange for their holdings of our common stock or stock options, as described under "Special Factors--Interests of Directors and Executive Officers in the Merger"; o in addition, officers and directors holding restricted ISP common stock have agreed to forfeit the stock in connection with the merger in exchange for a cash payment equal to the number of shares that were forfeited, multiplied by the merger consideration, payable subject to the vesting restrictions applicable to the underlying restricted shares; and o after the merger, ISP will continue indemnification arrangements and directors' and officers' liability insurance for our present and former directors and officers. MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES (SEE PAGE 33) The receipt of $10.30 in cash for each share of our common stock pursuant to the merger will be a taxable transaction for U.S. federal income tax purposes. For U.S. federal income tax purposes, each of our stockholders generally will realize taxable gain or loss as a result of the merger measured by the difference, if any, between $10.30 per share and the adjusted tax basis in that share owned by the stockholder. For additional information regarding material U.S. federal income tax consequences of the merger to our stockholders, see "Special Factors--Material U.S. Federal Income Tax Consequences of the Merger to our Stockholders." APPRAISAL RIGHTS (SEE PAGE 39) Stockholders who do not wish to accept the $10.30 per share cash consideration payable pursuant to the merger may seek, under the DGCL, judicial appraisal of the fair value of their shares by the Court of Chancery of the State of Delaware. This value could be more or less than or the same as the merger consideration of $10.30 in cash per share. This "right of appraisal" is subject to a number of restrictions and technical requirements. Generally, in order to exercise appraisal rights, among other things: o you must NOT vote in favor of the merger agreement; o you must make a written demand for appraisal in compliance with the DGCL before the vote on the merger agreement; and o you must continuously hold your shares from the date of making the demand through the effectiveness of the merger. A stockholder who is the record holder of shares of common stock on the date the written demand for appraisal is made, but who thereafter transfers those shares prior to the effectiveness of the merger will lose any right to appraisal in respect of those shares. Merely voting against the merger agreement will not preserve your right of appraisal under the DGCL. Also, since a submitted proxy not marked "against" or "abstain" will be voted for the adoption of the merger agreement, the submission of a proxy not so marked will result in the waiver of appraisal rights. If you hold shares in the name of a broker or other nominee, you must instruct your nominee to take the steps necessary to exercise your appraisal right. If you or your nominee fails to follow all of the steps required by Section 262 of the DGCL, you will lose your right of appraisal. Annex D to this proxy statement contains Section 262 of the DGCL relating to your right of appraisal. THE SPECIAL MEETING (SEE PAGE 36) DATE, TIME, PLACE AND MATTERS TO BE CONSIDERED (SEE PAGE 36). Our special meeting will be held at the offices of Simpson Thacher & Bartlett, 425 Lexington Avenue, New York, New York, on February ___, 2003 at _, local time. At the special meeting, you will be asked to vote on the adoption of the merger agreement. A copy of the merger agreement is attached as Annex A to this proxy statement. -------------------------------------------------------------------------------- 3 -------------------------------------------------------------------------------- RECORD DATE FOR VOTING (SEE PAGE 36). You may vote at the special meeting if you owned shares of our common stock at the close of business on January 10, 2003. On that date, there were 65,210,670 shares of our common stock outstanding and Mr. Heyman beneficially owned 52,567,240 shares of our common stock. Each share of common stock entitles the holder to cast one vote at the special meeting. PROCEDURES RELATING TO YOUR VOTE AT THE SPECIAL MEETING (SEE PAGE 36). o In order to have a quorum at the special meeting, a majority of all outstanding shares of common stock as of the record date must be present, in person or by proxy. Mr. Heyman has agreed, pursuant to a voting agreement, to cause all of the shares beneficially owned by him at the time of the meeting (but excluding shares held by qualified charitable organizations) to be represented in person or by proxy at the meeting. Accordingly, a quorum at the meeting is assured. A copy of the voting agreement is attached as Annex C to this proxy statement. o In order to adopt the merger agreement under the DGCL, we must obtain the affirmative vote of the holders of a majority of the shares of common stock outstanding and entitled to vote at the special meeting. As of the record date for the special meeting, Mr. Heyman and our directors and officers beneficially owned a total of 54,331,518 shares, which is approximately 83.3% of all outstanding shares. Mr. Heyman has agreed in a voting agreement to cause all of the shares beneficially owned by him at the time of the special meeting (but excluding shares held by qualified charitable organizations) to vote "FOR" the adoption of the merger agreement, which will assure adoption of the merger agreement under the DGCL. We also expect our other directors and executive officers to vote to adopt the merger agreement. o In addition, although not required under Delaware law or the amended and restated certificate of incorporation or by-laws of ISP, the merger agreement requires that the majority of the minority condition must be satisfied before we can complete the merger. o After carefully reading and considering the information contained in this proxy statement, you should complete, date and sign your proxy card and mail it in the enclosed return envelope as soon as possible so that your shares are represented at the special meeting, even if you plan to attend the meeting in person. Unless you specify to the contrary, all of your shares represented by valid proxies will be voted "FOR" the adoption of the merger agreement. Abstentions, failures to vote and broker non-votes will have the same effect as a vote against the adoption of the merger agreement for purposes of obtaining a majority of all shares of ISP common stock. However, abstentions, failures to vote and broker non-votes will not affect satisfaction of the majority of the minority condition. o If your shares are held in "street name" by your broker, your broker will vote your shares, but only if you provide written instructions to your broker on how to vote. You should follow the procedures provided by your broker regarding how to instruct it to vote your shares. Without instructions, your shares will not be voted by your broker. o Until exercised at the special meeting, you can revoke your proxy and change your vote in any of the following ways: o by delivering written notification of revocation to our Secretary at our executive offices at 1361 Alps Road, Wayne, New Jersey 07470, o by delivering a proxy of a later date, o by attending the special meeting and voting in person. Your attendance at the special meeting will not, by itself, revoke any proxy previously delivered by you; you must vote in person at the meeting, or o if you have instructed a broker to vote your shares, by following the directions received from your broker to change those instructions. For additional information regarding the procedure for delivering your proxy see "The Special Meeting--Voting and Revocation of Proxies" and "The Special Meeting--Solicitation of Proxies." If you have more questions about the merger or how to submit your proxy, or if you need additional copies of this proxy statement or the enclosed proxy card or voting instructions, you should contact Georgeson Shareholder Communications Inc., 17 State Street - 10th Floor, New York, NY 10004, (212) 440-9800. -------------------------------------------------------------------------------- 4 -------------------------------------------------------------------------------- ACCOUNTING TREATMENT (SEE PAGE 38) We will account for the merger under the purchase method of accounting. See "The Merger--Accounting Treatment." THE MERGER AGREEMENT (SEE PAGE 42) CONDITIONS TO THE MERGER (SEE PAGE 46). The completion of the merger depends on the satisfaction or waiver of a number of conditions, including the following: o we must obtain the affirmative vote of the holders of a majority of the outstanding shares of ISP common stock; o the majority of the minority condition must be satisfied; o no injunction or similar prohibition to completion of the merger may be in effect and no proceeding by a governmental authority may have been commenced seeking to impose such an injunction or prohibition; o our and ISPH's respective representations and warranties in the merger agreement must be true and correct, subject to exceptions that would not have a material adverse effect on the party making the representations or warranties or the consummation of the merger; and o we and ISPH must each be in compliance in all material respects with our respective covenants in the merger agreement. TERMINATION OF THE MERGER AGREEMENT (SEE PAGE 46). We (with the approval of the special committee) and ISPH may agree to terminate the merger agreement at any time before the completion of the merger. ISPH may terminate the merger agreement without our consent if our board of directors or the special committee withdraws, qualifies or modifies its approval of the merger agreement or its recommendation to ISP's stockholders to adopt the merger agreement, or publicly proposes to do so, or takes any other action or makes any other statement inconsistent with that recommendation. However, if ISPH chooses not to terminate the merger agreement in such an event, we will not be entitled to terminate the merger agreement and will be required to submit the merger agreement to our stockholders for consideration at the special meeting. In addition, we (with the approval of the special committee) or ISPH may terminate the merger agreement by written notice to the other if: o any governmental entity issues a final nonappealable injunction or other governmental order permanently enjoining or otherwise prohibiting the merger; o the merger is not completed on or before May 31, 2003, unless the failure to complete the merger is due to the failure of the party seeking to terminate the merger agreement to fulfill its obligations under the merger agreement; o the other party materially breaches a representation, warranty or covenant in the merger agreement and the breach is not cured within 30 days after notice of the breach or cannot be cured prior to May 31, 2003; or o at the special meeting, the merger agreement is not adopted by the required votes of the holders of ISP common stock; except that this right to terminate will not be available to ISPH if Mr. Heyman has failed to cause the shares beneficially owned by him at the time of the special meeting (but excluding shares held by qualified charitable organizations) to vote in favor of the adoption of the merger agreement. EFFECT OF TERMINATION (SEE PAGE 47). If the merger agreement is terminated by either ISP or ISPH, there will be no liability on the part of ISP, ISPH or any of their affiliates, directors, officers, employees or stockholders. However, no party will be relieved from liability for willful breaches of the merger agreement. -------------------------------------------------------------------------------- 5 -------------------------------------------------------------------------------- INFORMATION ABOUT ISP, MR.

SELECTED CONSOLIDATED FINANCIAL DATA OF ISP Set forth below are our selected consolidated financial data. The selected financial data were derived from the historical financial statements and related notes of ISP. On July 15, 1998, International Specialty Products Inc. merged with and into ISP Holdings Inc., which changed its name to International Specialty Products Inc.

On July 8, 2002, the last full trading day prior to the initial announcement of the merger proposal, the last reported sale price per share was $7.95. On January 30, 2003, the most recent practicable trading day prior to the date of this proxy statement, the last reported sales price per share was $10.25. Stockholders should obtain current market price quotations for the common stock in connection with voting their shares. The merger agreement provides that neither our board of directors nor any committee of our board of directors will declare or pay any dividend until the closing of the merger, except with the consent of ISPH. Several of our significant subsidiaries are subject to financial and operating covenants, including limitations on the payment of cash dividends, under the credit agreement and indentures to which the subsidiaries are party. We have not provided any pro forma data giving effect to the proposed merger. We do not believe that information is material to our stockholders in evaluating the merger agreement because the proposed merger is all cash and, if completed, our common stock would cease to be publicly traded. We also have not provided any separate financial information for ISPH since it is a special purpose entity formed in connection with the proposed merger and has no independent operations. -------------------------------------------------------------------------------- 7 SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS The Securities and Exchange Commission encourages companies to disclose forward-looking information so that investors can better understand a company's future prospects and make informed investment decisions.

As a result, the liquidity of the market for ISP's common stock has remained consistently limited, with an average daily trading volume of only 21,850 shares during the 360 days prior to July 8, 2002. ISP has from time to time taken steps to attempt to improve the liquidity and trading value of its common stock. In particular, in 1998, ISP explored the possibility of publicly offering additional shares of its common stock in order to increase the liquidity of the public trading market for ISP's common stock. At that time, ISP filed a "shelf" registration statement on Form S-3 with the Securities and Exchange Commission. However, in light of market conditions, and the reluctance of institutional investors to purchase stock of a company with a small public float, ISP concluded that such a public offering would not be feasible on terms that were economically attractive and withdrew the registration statement. Upon concluding that its common stock was undervalued in the market, ISP from time to time engaged in share repurchases in an effort to enhance stockholder value. These repurchases, however, further limited the liquidity of the trading market for ISP's common stock. In light of the failure of the foregoing actions to significantly improve the market performance of ISP's common stock, and for the reasons further described below under "Reasons for the Merger; Purpose and Structure of the Merger", in March 2002, Mr. Heyman began to explore preliminarily the possibility of pursuing a going private transaction. Mr. Heyman's decision to begin considering such a transaction at that time was influenced by the combination of the factors described above and Mr. Heyman's belief that the recent stock market downturn, together with ISP's relatively small public float, would have a further long-term negative impact on ISP's efforts to increase investor interest and enhance the market performance of ISP's common stock. As a result, Mr. Heyman began to believe that a transaction that would provide ISP's stockholders with a near-term cash premium for their shares while eliminating the costs and other burdens of maintaining ISP as a public company might benefit all of ISP's stockholders. During that period, he conducted an analysis as more fully described under "--Position of Mr. Heyman Regarding Fairness of the Merger." Based on that analysis, Mr. Heyman determined preliminarily that it might be advisable to seek to effect a transaction in which the holders of common stock of ISP (other than shares beneficially owned by Mr. Heyman) would each receive a cash payment in exchange for their shares. In April 2002, Mr. Heyman retained Simpson Thacher & Bartlett as legal counsel to provide advice regarding a possible transaction. Mr. Heyman considered several transaction structures, including making a direct offer to ISP's stockholders through a cash tender offer or negotiating with an independent special committee of ISP's board of directors to effect a merger with ISP. During May and early June 2002, Mr. Heyman, with the assistance of certain members of ISP's management, explored financing alternatives for a tender offer for the public shares of ISP and held numerous discussions with potential lenders to determine the viability of such a transaction. Mr. Heyman ultimately concluded that a merger structure would be preferable to a tender offer because a merger would (1) enable ISP's independent directors to negotiate directly for a price they believed to be fair and to reject any proposal they concluded was not in the best interests of ISP's public stockholders and (2) eliminate the need for third party tender offer financing. During the remainder of June and through July 8, 2002, Mr. Heyman continued to explore the desirability of pursuing such a going private transaction by means of a merger. On July 8, 2002, Mr. Heyman decided to proceed with the going private proposal and delivered a letter to the board of directors of ISP proposing a transaction that would result in Mr. Heyman acquiring beneficial ownership of all of the common stock of ISP not beneficially owned by him for a cash purchase price of $10 per share. The closing price for ISP's common stock on the New York Stock Exchange on July 8, 2002 was $7.95. Thus, the price proposed by Mr. Heyman represented a 26% premium over this closing price on the day before the proposal was announced. 9 The letter delivered to the board of directors of ISP is set forth below: July 8, 2002 International Specialty Products Inc. Board of Directors 1361 Alps Road Wayne, NJ 07470 Gentlemen: The focus of our interest at ISP has always been to increase shareholder value for all ISP shareholders. Nonetheless, our efforts have been hampered, at least in part, by the following: first, attracting analyst coverage and public investors to a Company with a majority shareholder and a small public float is inherently difficult and has been made more so by the general stock market downturn; and, second, I believe that investors have not given us sufficient credit for the not insubstantial earnings which have in the past been generated by the Company's investment portfolio, notwithstanding our outstanding investment performance over the years. As you know, we have sought to take steps in the past to address some of these issues. For example, on several occasions, ISP has explored the possibility of offering additional common shares to increase stock market liquidity, but concluded that such offering would not make economic sense. Alternatively, believing that our common stock was undervalued in the market, ISP has from time to time engaged in share repurchases in order to enhance shareholder value. While these repurchases had a compelling economic rationale, they inevitably had the adverse effect of further limiting the liquidity of the trading market for ISP stock. As a result, ISP has been unable to realize many of the benefits normally associated with public ownership. The following are just two examples: (1) ISP has not been able to utilize its common stock as currency for acquisitions; and (2) the lack of liquidity with respect to the Company's stock has impaired its ability to use stock options or equity-based incentives as a meaningful way to attract and retain employees. Accordingly, I am proposing that the Company be taken private in a transaction in which the shareholders, other than my affiliates and myself, would receive $10 per share in cash. This price represents an almost 45% premium over the average price for the prior 30 days. I expect that the Board will form a committee of independent Board members to evaluate my proposal, and wish to assure you that I am most interested, as I'm sure you are, in providing for the utmost of procedural fairness in the interests of ISP's minority shareholders. In this connection, we propose that approval of any transaction require the vote of a majority of the minority shareholders. I am willing to meet with you promptly in order to discuss this proposal, and I would hope that we could move forward expeditiously to consider this proposed transaction. Sincerely, /s/ Samuel J. Heyman ISP issued a press release shortly after its board of directors received the letter announcing the proposal and the price suggested by Mr. Heyman. Shortly after ISP issued the press release, six purported class action suits were filed in the Court of Chancery of the State of Delaware against ISP and members of its board of directors. These six suits have been consolidated. On July 12, 2002, a purported class action suit was also filed in the United States District Court, District of New Jersey, against ISP and members of its board. The New Jersey claim was subsequently amended to assert derivative claims as well. The Delaware and New Jersey complaints allege, among other things, that the defendants have breached fiduciary and other duties in connection with the proposed transaction. These complaints variously seek a court order enjoining the proposed transaction, an award of unspecified damages and attorneys' fees, the unwinding of any transaction and other unspecified equitable relief. 10 After receiving the proposal letter from Mr. Heyman, the independent members of ISP's board of directors (Robert Englander, Sanford Kaplan, Burt Manning and Alan M. Meckler) met to discuss an appropriate response to the proposal. The independent directors decided to investigate and interview potential financial and legal advisors. During the remainder of July and early August, ISP's independent directors held several conversations with each other and with ISP's other directors and management concerning the foregoing matters. In addition, the independent directors also discussed the possible composition of a special committee and discussed with the other directors and ISP's general counsel, the possible compensation and indemnification arrangements that might apply to the members of such a special committee. During that period, the independent directors also determined that Willkie Farr & Gallagher should be retained as counsel to the special committee. Among the factors considered by the independent directors in making this determination was the fact that Willkie Farr & Gallagher had not previously acted as counsel to ISP or, during the past approximately 20 years, Mr. Heyman. The independent directors met on August 1, 2002 to interview and discuss several investment banking firms as potential financial advisors. On August 7, 2002, the board of directors of ISP held a telephonic meeting for the purpose of appointing a special committee to evaluate the merger proposal. In addition to ISP's directors, attending the meeting were ISP's general counsel, representatives of Willkie Farr & Gallagher and representatives of Simpson Thacher & Bartlett, counsel to Mr. Heyman and ISPH. During the meeting, Mr. Heyman confirmed his continuing interest in acquiring beneficial ownership of 100% of ISP, briefly summarized his merger proposal and acknowledged the appropriateness of the appointment of a special committee of directors who are not members of management or affiliated with Mr. Heyman to negotiate on behalf of ISP's minority stockholders. Mr. Heyman also informed the board of directors that he had no present intention to cause the shares of ISP common stock beneficially owned by him to be sold. The board of directors then voted to form a special committee composed of three independent directors, Robert Englander, Burt Manning and Alan M. Meckler. The board authorized the special committee to: o review and evaluate the merger proposal; o negotiate to the extent it deemed appropriate with Mr. Heyman with respect to the proposal; o determine, on behalf of the board of directors, whether the proposed transaction was fair to, and in the best interests of, ISP and the unaffiliated holders of ISP's common stock; o recommend what action, if any, should be taken with respect to the merger proposal; and o otherwise exercise the power of the board of directors in connection with the merger proposal. The board also determined not to authorize or recommend the merger proposal in absence of a favorable recommendation by the special committee. Because Mr. Heyman informed ISP's board of directors that he was not interested in having the shares he beneficially owns in ISP sold, the board did not authorize the special committee, and the special committee did not seek authority, to solicit the interest of third-parties in a potential sale of ISP. In addition, the board determined that each member of the special committee would receive $18,000 for his services and reimbursement of expenses related to the special committee's activities, which compensation and reimbursement would be payable whether or not the special committee recommended the merger proposal and whether or not any proposed transaction was consummated. The board also authorized ISP to enter into indemnity agreements with the members of the special committee and formally authorized the committee to engage independent legal, financial and other advisors selected by the special committee. Pursuant to indemnity agreements dated August 7, 2002, ISP agreed to indemnify Messrs. Englander, Manning and Meckler for any expenses, liabilities and losses relating to their service as members of the special committee and/or the board of directors in connection with the transaction. These indemnity agreements are in addition to the indemnity available to the special committee members pursuant to ISP's amended and restated certificate of incorporation and by-laws. Following the board meeting on August 7, 2002, the special committee met with Willkie Farr & Gallagher to further discuss potential financial advisors and to review the terms of the draft merger agreement received from Simpson Thacher & Bartlett. The special committee authorized Willkie Farr & Gallagher to commence negotiations with Mr. Heyman and his representatives regarding the terms of the merger agreement. The special committee also authorized Willkie Farr & Gallagher to commence negotiations with Lehman Brothers concerning the terms of its possible engagement as financial advisor to the special 11 committee. Among the factors considered by the special committee in its selection of Lehman Brothers was its consideration of past relationships between Lehman Brothers and ISP and Mr. Heyman and its determination that Lehman Brothers had not had a material relationship with, nor had it acted as financial advisor to, ISP, ISPH or Mr. Heyman within the past two years. In August 2002, Simpson Thacher & Bartlett and Willkie Farr & Gallagher held preliminary discussions regarding the terms of the merger agreement, other than the price per share to be paid pursuant to the merger agreement. On August 29, 2002, the special committee entered into an engagement letter with Lehman Brothers to act as the committee's financial advisor and, on September 4, 2002, ISP issued a press release announcing the engagement. Over the course of mid- to late-August, 2002, Lehman Brothers reviewed financial and other information provided by ISP, including ISP's business plan and other materials. On September 3, 2002, members of ISP's senior management met with representatives of Lehman Brothers and Willkie Farr & Gallagher in connection with Lehman Brothers' due diligence review of ISP. ISP's management made a formal presentation regarding the financial condition and results of operations of ISP's chemical business (which is conducted by ISP's subsidiary, ISP Chemco Inc.) and also reviewed copies of ISP's capitalization structure and sales and five-year projections through 2006 of ISP's chemical business (the "Five-Year Plan"), which had been prepared by ISP's management in December 2001 and presented to ISP's board of directors in April 2002. ISP's management summarized ISP's earnings forecasts for the various business segments reflected in the Five-Year Plan and also provided a comparison of the financial performance of those businesses for the first half of 2002 with its planned first half financial performance as reflected in the Five-Year Plan. ISP's management informed Lehman Brothers that operating income of $63.0 million for the first six months of 2002 for the chemicals businesses (excluding the investment activities of ISP's investment subsidiary) was $1.4 million higher than projected. They also reported that better-than-expected results in the fine chemical business ($4.9 million above projections), the industrial segment ($4.0 million above projections) and the minerals segment ($4.6 million above projections) had been mostly offset by substantially-lower-than-projected results in ISP's core chemicals business ($12.1 million below projections). See "--ISP's Forecasts" below. ISP's management explained to Lehman Brothers that much of the better-than-expected operating income for the industrial, fine chemicals and minerals segments resulted from non-recurring events, including (1) in the case of the industrial segment, a significant delay in the opening of a competing plant by a major competitor of ISP, (2) in the case of the fine chemicals segment, resolution of a contractual obligation of a major customer that filed bankruptcy and (3) in the case of the minerals segment, a significant increase in granules sales to the roofing industry driven by the strong housing market in the first half of 2002. ISP's management also informed Lehman Brothers that ISP's core chemicals business was facing substantially greater pricing pressure than management had anticipated when it had prepared its Five-Year Plan. Based on the first-half results, ISP's management revised its 2002 full-year budget from the Five-Year Plan and presented the revised full-year 2002 projections to Lehman Brothers during the September 3, 2002 meeting. The revised current-year projections were prepared consistent with ISP's normal financial planning and reporting practices, pursuant to which ISP management updates its current-year internal forecasts from time to time during the course of the year to take into account actual results achieved during the year. The revised full-year 2002 projections and the original projections reflected in the Five-Year Plan prepared in December 2001 are set forth under "--ISP's Forecasts" below. ISP's management informed Lehman Brothers that, since the time of the preparation of the Five-Year Plan in December 2001, ISP's management had not revised any of its projections for any period after calendar year 2002 because while, as noted above, ISP updates its current-year forecasts throughout the year as part of its ongoing financial planning process, projections for later years and the Five-Year Plan as a whole would ordinarily be reviewed and updated in the fourth quarter of each year in connection with ISP's normal annual budgeting process. Accordingly, the effects of the revisions and trends observed in 2002 with respect to individual business segments were not taken into account in the projections contained in the Five-Year Plan for calendar years 2003 through 2006. In addition, management noted that the weakened performance in the core chemicals segment, which resulted from substantial pricing pressure from competitors and from price discounts demanded by customers, was expected to continue into 2003 and potentially beyond. On September 18, 2002, Lehman Brothers presented the special committee with a preliminary financial review of the proposed transaction based on information it had received or reviewed to date, including a review of ISP's business segments, competitors, financial forecasts from the Five-Year Plan and a review of various valuation methodologies that it would perform. Although it had not yet finalized its due diligence, Lehman Brothers also presented a preliminary valuation of ISP based on the forecasts from the Five-Year Plan and using a comparable trading analysis, an industry transaction analysis, a discounted cash flow analysis and a transactions premia paid analysis. Lehman Brothers noted that it had not discussed its preliminary financial analysis with 12 ISP management. Based on these points, the special committee instructed Lehman Brothers to undertake further steps as it deemed necessary to complete its analyses, including scheduling additional meetings with ISP's management to share its approach to value and obtain any further information management believed relevant to Lehman Brothers' evaluation. On September 20, 2002, Lehman Brothers met again with members of ISP's senior management team to discuss its preliminary financial analyses (excluding any preliminary valuation ranges derived from those analyses). Also present at that meeting were representatives of Willkie Farr & Gallagher and Simpson Thacher & Bartlett. During the course of the September 20, 2002 meeting, Susan B. Yoss, ISP's Executive Vice President, Finance and Treasurer, Neal E. Murphy, ISP's Senior Vice President and Chief Financial Officer, and Richard A. Weinberg, ISP's Executive Vice President, General Counsel and Secretary, indicated their disagreement with a number of the assumptions and other parameters reflected in Lehman Brothers' preliminary analysis. Ms. Yoss and Mr. Weinberg are also officers of ISPH. In light of the fact that ISPH and Mr. Heyman had not engaged a separate financial advisor, Ms. Yoss and Mr. Weinberg were present at this meeting as representatives of ISPH and Mr. Heyman in order to review the methodology and analysis of Lehman Brothers. Mr. Murphy, who is not an officer of ISPH, was acting as a representative of ISP management during these meetings primarily in order to address factual matters relating to the financial information and projections underlying Lehman Brothers' analysis. ISP's board of directors recognized that members of senior management, including Ms. Yoss and Mr. Weinberg, would continue to work for ISP after the consummation of any possible merger and have a potential conflict of interest with respect to pricing issues. The board of directors, therefore, established the special committee to negotiate on behalf of ISP and engaged Lehman Brothers and Willkie Farr & Gallagher to assist the special committee in representing the interests of ISP and its unaffiliated stockholders during negotiations. Notwithstanding these potential conflicts of interest, Lehman Brothers' representatives agreed to listen to the views of Ms. Yoss and Mr. Weinberg and accorded their opinions the same consideration customarily given to those of a separate financial advisor representing an acquiror. In addition, Lehman Brothers' representatives solicited the views of Mr. Murphy, as a representative of ISP management. During the September 20, 2002 discussions, Ms. Yoss and Mr. Weinberg expressed their belief that certain of the companies included by Lehman Brothers in ISP's peer group were not comparable to ISP because of the companies' differing product offerings, core businesses and size. In addition, Ms. Yoss and Mr. Weinberg noted their belief that the universe of precedent transactions chosen for purposes of Lehman Brothers' comparative analyses was not sufficiently comprehensive. They expressed their belief that the analysis should have included (1) additional transactions from a broader time range so as to include acquisitions that took place during periods of weak economic growth and stock market performance (and not just those effected during a period of unusually strong economic growth) and (2) only transactions involving companies with a controlling stockholder and a proportionately small public float. Finally, Ms. Yoss stated her opinion that the discount factor and perpetuity growth rates used by Lehman Brothers in its discounted cash flow analysis did not adequately reflect ISP's cost of capital and historical operating performance and, therefore, resulted in a higher than appropriate discounted cash flow valuation. In addition, Ms. Yoss and Mr. Weinberg noted their belief that the substantial decline in the performance of the stock market generally and of the S&P Midcap Specialty Chemicals Index, in particular, was not adequately factored into Lehman Brothers' analysis of ISP's trading price. Ms. Yoss and Mr. Weinberg believed that ISP's stock price would likely be substantially lower than the closing price immediately prior to Mr. Heyman's merger proposal. Finally, Mr. Weinberg and Ms. Yoss expressed their belief that ISP's ability to achieve the results reflected in the Five-Year Plan was uncertain and that there were greater downside risks than upside opportunities in the plan. Specifically, they expressed their view that, based on their preliminary review of developments and operating results since December 2001, there was approximately $5 million to $10 million in risk to operating profit relative to the Five-Year Plan in 2003, with the risk growing in line with sales through 2006. The Lehman Brothers representatives indicated that while they would consider the input received at the meeting, they were bound to rely on the written projections of ISP's management for purposes of their financial analysis. Accordingly, Lehman Brothers noted that if ISP management believed the projections in the Five-Year Plan were no longer up to date, ISP management should provide more current projections. At a special committee meeting later that day, Lehman Brothers reviewed the perspectives conveyed by Ms. Yoss and Mr. Weinberg regarding Lehman Brothers' valuation methodology. Lehman Brothers also discussed the views of ISP management, as described by Mr. Murphy, regarding the projections previously provided to Lehman Brothers. Lehman Brothers did not provide a valuation analysis to the special committee at this meeting. On September 27, 2002, the special committee met to discuss the proposed transaction and to hear a supplemental presentation from Lehman Brothers. The supplemental presentation was substantially similar to Lehman Brothers' presentation on September 18, 2002, except that Lehman Brothers updated its written materials to provide revised valuations based on recent market activity and certain additional expenses of ISP that ISP management had identified at the meeting on September 20, 13 2002 as having been omitted from Lehman Brothers' September 18, 2002 analysis. In addition, in response to discussions with Ms. Yoss and Mr. Weinberg on September 20, 2002, Lehman Brothers supplemented its earlier presentations to provide the special committee with additional information suggested by Ms. Yoss and Mr. Weinberg regarding additional comparable companies, additional industry transactions and an analysis of the "unaffected" trading price of ISP. Although Lehman Brothers considered the additional information, such information did not change its conclusion as to the fairness of the merger consideration from a financial point of view. Following that meeting, representatives of Willkie Farr & Gallagher communicated the special committee's view that, based on Lehman Brothers' preliminary financial analysis to date and discussions with Lehman Brothers on the methods of valuations utilized, the performance of ISP's stock in the marketplace, the projections of ISP's management provided to Lehman Brothers on September 3, 2002, and the special committee's belief that, if requested by the special committee, Lehman Brothers would be unable to issue a fairness opinion at that time, the special committee was not then prepared to recommend the $10 merger proposal. On October 3, 2002, representatives of Lehman Brothers met again with Mr. Weinberg and Ms. Yoss to further discuss their respective views on the appropriate assumptions and methodologies for conducting a financial analysis of ISP and the pending merger proposal. Also present at that meeting were representatives of Willkie Farr & Gallagher and Simpson Thacher & Bartlett. Ms. Yoss and Mr. Weinberg once again expressed their views regarding the assumptions and methodologies underlying Lehman Brothers' valuation analyses. They reiterated their belief that ISP's ability to achieve the results reflected in the Five-Year Plan was highly uncertain and again summarized the trends in ISP's various business segments that lead to that uncertainty. Furthermore, Mr. Weinberg noted that Mr. Heyman had indicated that, in light of the severe market downturn since the date of the merger proposal, Mr. Heyman was finding it increasingly difficult to sustain a merger proposal at the $10 per share price. Following that meeting, in light of the continued belief by ISP management that the analyses performed by Lehman Brothers did not adequately reflect the uncertainty inherent in ISP's financial outlook and diminished prospects for the company since the preparation of the Five-Year Plan, ISP's management agreed to provide Lehman Brothers with more current projections that would more fully reflect the impact of business developments -- primarily substantially greater than anticipated pricing pressures in ISP's core chemicals and minerals businesses -- that had occurred subsequent to the preparation of the Five-Year Plan in December 2001. On October 10, 2002, Lehman Brothers met with ISP's management team and other ISP personnel at ISP, at which time ISP's management presented updated five-year projections (the "Updated Projections") to Lehman Brothers, including those set forth under "--ISP's Forecasts" below. The discussions highlighted certain differences between the original Five-Year Projections and the Updated Projections. ISP's management provided a detailed presentation regarding the manner in which the Updated Projections were prepared and the factors and developments leading to the differences between the Updated Projections and the projections reflected in the Five-Year Plan and answered questions regarding the Updated Projections. In particular, ISP's management explained that, while the revised 2002 projections presented on September 3, 2002 were substantially accurate, the projections for the subsequent four years had not been updated for developments in the business of ISP, the specialty chemicals industry and the economy generally since December 2001. ISP's management advised Lehman Brothers that as a result of these changes, the Updated Projections replaced the Five-Year Plan as management's best currently available estimates and judgments as to the future financial performance of ISP. The Updated Projections were based on several changed factors, including pricing pressures in the personal care and specialty chemicals segments, softness of demand in growth markets such as Asia and contemplated changes in the pricing terms of a major supply contract. On October 21, 2002, the special committee met with members of ISP's senior management and Mr. Heyman to discuss, among other things, the Updated Projections and to continue its discussions regarding the merger proposal. Also present at that meeting were representatives from Willkie Farr & Gallagher, Simpson Thacher & Bartlett and Lehman Brothers. After presenting information concerning the Updated Projections to the special committee, ISP's management and Mr. Heyman answered questions posed by the special committee members and representatives from Lehman Brothers. After ISP's management, Mr. Heyman and representatives from Simpson Thacher & Bartlett left the meeting, Lehman Brothers gave a presentation to the special committee highlighting certain differences between the original Five-Year Plan and the Updated Projections, as well as a preliminary valuation using the Updating Projections based on the same methodologies that had previously been presented to the special committee. After considerable discussion regarding the Updated Projections, the special committee concluded that, based on the performance of ISP's stock in the marketplace, the projections of ISP's management, consideration of Lehman Brothers' methods of valuation and preliminary financial analysis to date, as well as the special committee's belief that $10 per share did not represent the highest price available to ISP's stockholders, the special committee would not recommend the merger proposal at $10 per share. Following the October 21, 2002 meeting, the special 14 committee's legal advisor and Mr. Heyman's legal advisor had numerous conversations regarding the parties' respective views concerning the appropriate per share price in the merger. Although the special committee had not identified a specific price or range of prices that would be an acceptable alternative to Mr. Heyman's $10 merger proposal, the special committee's legal advisor indicated to Mr. Heyman's legal advisors that the special committee was not prepared to recommend the merger at the $10 per share price because it did not believe that the offer represented the highest price available to ISP's stockholders, and, accordingly, sought to negotiate a higher price per share. Mr. Heyman continued to believe the proposed merger consideration was fair and, accordingly, instructed his legal advisors that, while he was willing to explore non-price contractual changes to the merger agreement and a possible settlement of the pending stockholder litigation referred to above, Mr. Heyman would not authorize an increase in the merger consideration. Furthermore, Mr. Heyman's representatives informed the special committee's legal advisors that Mr. Heyman continued to be concerned about the advisability of sustaining the merger proposal in light of the deterioration in market conditions and that Mr. Heyman might consider withdrawing the merger proposal if the special committee concluded it could not recommend the proposed transaction at $10 per share. On October 25, 2002, counsel for Mr. Heyman met with plaintiffs' counsel in the stockholder litigation in Delaware to discuss a potential settlement of the litigation. Counsel for Mr. Heyman also attempted to include plaintiffs' counsel in the stockholder litigation pending in New Jersey in the settlement discussions. In light of the firm position of the special committee that it would not recommend a transaction at $10 per share, on October 30, 2002, Mr. Heyman concluded that exploring an increase in the merger consideration would be preferable to abandoning the proposed transaction and authorized his legal advisors to explore with the special committee's legal advisors a possible increase in the per share merger consideration to $10.25, subject to the prompt negotiation of a mutually acceptable merger agreement, approval of the agreement by the entire special committee and settlement of the stockholder litigation. On October 30, 2002, in a meeting of the special committee, representatives of Willkie Farr & Gallagher reported that Mr. Heyman's representatives had advised them that Mr. Heyman would be willing to increase the per share merger consideration to $10.25. The special committee discussed whether to accept $10.25 per share but, in an effort to increase the per share merger consideration and achieve the best possible price for ISP's stockholders, instructed Willkie Farr & Gallagher to advise Mr. Heyman's representatives that the special committee was not in a position to recommend the proposed transaction at $10.25 at that time, and further instructed Willkie Farr & Gallagher to propose an offer price of $10.50 per share. On October 31, 2002, the special committee's legal advisors conveyed the special committee's views to Mr. Heyman's legal advisors. In response, Mr. Heyman's representatives advised the special committee's legal advisors that Mr. Heyman would not increase the merger consideration to $10.50 and that if prompt agreement could not be reached by the parties at a merger price of $10.25 per share, Mr. Heyman would consider withdrawing his offer. On November 1, 2002, the special committee met, along with representatives of Willkie Farr & Gallagher and Lehman Brothers to further discuss the proposed transaction. On November 4, 2002, Mr. Heyman authorized his legal advisors to indicate his potential willingness to increase the per share merger consideration to $10.30 per share. In a meeting on that day, the special committee discussed the fairness of the proposal to ISP's unaffiliated stockholders and agreed to reject the proposal of $10.30 per share, but, in an effort to maximize value for ISP's stockholders, to inform Mr. Heyman's representative that, while it was not in a position to recommend the proposed transaction at $10.30 per share at that time, it would consider recommending the proposal at $10.35 per share. Mr. Heyman's representative stated that Mr. Heyman would not accept that share price, and that if the special committee could not recommend the proposed transaction at $10.30 per share that Mr. Heyman would withdraw the offer. The special committee evaluated the possibility of turning down the proposed merger consideration and remaining a public company, but was concerned that such decision might result in the minority stockholders losing the opportunity to receive $10.30 per share. If Mr. Heyman were to withdraw the offer, the price of ISP's publicly-traded stock would likely fall significantly from its closing price of $9.40 on November 1, 2002. The special committee noted that the market in general or the specialty chemical sector could deteriorate further, lowering the market price of the shares. The special committee also considered each of Lehman Brothers' preliminary financial analyses presented to it on October 21, 2002, the implied valuations resulting from each of those analyses and that Lehman Brothers would most likely be in a position to issue a fairness opinion with respect to a proposal of $10.30 per share. The special committee further considered that the proposed price was within the comparable trading, premiums paid in going private transactions with less than a 50% minority ownership, premiums paid in going private transactions with less than a 20% minority ownership, premiums paid in unaffected going private transactions, premiums paid in full acquisitions and discounted cash flow valuation ranges analyzed in Lehman Brothers' presentations. The special committee further noted that if the special committee rejected the proposed merger consideration and Mr. Heyman withdrew his offer, the 15 stockholders would lose the opportunity to vote on the proposed merger, which would likely prove to be the best option available to the stockholders. For further discussion of valuation methods and ranges that the special committee considered, see "--Opinion of Lehman Brothers" below. Finally, the special committee noted that it was unlikely that a third party would attempt to purchase ISP stock held by minority stockholders due to Mr. Heyman's substantial beneficial ownership interest in ISP. Between November 4 and November 6, the parties' legal advisors completed negotiations of the open contractual terms in the merger agreement and voting agreement. Settlement discussions between counsel for Mr. Heyman and plaintiffs' counsel in the pending stockholder litigation in Delaware and New Jersey also continued during this period. On November 6, 2002, the special committee met to discuss Mr. Heyman's response to the special committee's attempts to increase the offer price of $10.30 per share. Lehman Brothers presented a financial analysis of the offer and orally delivered its opinion, which it committed to deliver later in writing, that, as of that date and based upon and subject to the assumptions, limitations and qualifications set forth in the Lehman Brothers' written opinion, the proposed transaction at $10.30 per share was fair, from a financial point of view, to ISP's unaffiliated stockholders. Ultimately, the special committee concluded that the proposed merger was substantively and procedurally fair to ISP's unaffiliated stockholders and that the opportunity to receive $10.30 cash per share should be presented to ISP's stockholders. In reaching that conclusion, the special committee noted that the adoption of the merger agreement at that price would be subject to acceptance by a majority of the minority stockholders voting at the special meeting to consider approval of the merger. After further discussion and deliberation and taking into account all of the factors noted above, the special committee unanimously (1) concluded that the proposed transaction was advisable, fair to, and in the best interests of, the unaffiliated stockholders of ISP, and (2) agreed to recommend that our board approve the terms of the proposed transaction. Later that day, Willkie Farr & Gallagher reported the special committee's decision to ISP. On November 7, the parties announced that Mr. Heyman and the special committee had reached an agreement with respect to the merger at a price of $10.30 per share in cash, subject to approval by ISP's board of directors. On November 8, 2002, the special committee met to approve the proposed resolutions, which (1) concluded that the proposed transaction at $10.30 per share was advisable, fair to, and in the best interests of, the unaffiliated stockholders of ISP, and (2) recommended that the full board approve the terms of the proposed transaction. Later that day, our board of directors met to consider approval of the merger agreement. At the meeting, Lehman Brothers once again presented a financial analysis of the transaction that was substantially identical to the analysis presented to the special committee on November 6, 2002 in connection with Lehman Brothers' rendering of its oral opinion. The board also reviewed the terms of the merger agreement. Thereafter, based on the unanimous recommendation of the special committee, the board determined that the proposed merger was advisable, fair to, and in the best interests of, ISP's unaffiliated stockholders. Each director (other than Mr. Heyman and Sunil Kumar, who abstained) voted to approve the merger and voting agreements and recommend that ISP's stockholders vote to adopt the merger agreement. Following settlement discussions between counsel for Mr. Heyman and counsel for plaintiffs in the Delaware and New Jersey litigations, the parties to the stockholder litigation pending in Delaware agreed on and, on November 19, 2002, executed a memorandum of understanding to reflect a proposed settlement of the Delaware litigation. The parties also agreed, subject to various conditions, to enter into a settlement agreement, cooperate in public disclosures related to the settlement and use best efforts to gain approval of the settlement by the Delaware courts. Without any admission of fault by the defendants, the memorandum of understanding contemplates a dismissal of all claims with prejudice and a release in favor of all defendants of any and all claims related to the merger that have been or could have been asserted by the plaintiffs or any members of the purported class (including the pending claims in the New Jersey litigation). The settlement is subject to, among other factors, completion of confirmatory discovery, execution of a settlement agreement and final approval of the settlement by the Court of Chancery of the State of Delaware and completion of the merger. RECOMMENDATIONS OF THE SPECIAL COMMITTEE The special committee has unanimously determined that the merger agreement is advisable, fair to and in the best interests of the unaffiliated stockholders of ISP, and unanimously determined to recommend to our board of directors that the board of directors: o approve the merger agreement and the voting agreement; 16 o declare the advisability of the merger agreement; and o recommend that the stockholders of ISP vote to adopt the merger agreement. RECOMMENDATIONS OF OUR BOARD OF DIRECTORS The board of directors of ISP consists of six directors, three of whom served on the special committee and two of whom are also directors of ISPH and, therefore, abstained from voting with regard to the merger. At the November 8, 2002 meeting of the board of directors, the special committee, with its legal and financial advisors participating, reported to the other members of the board of directors on the course of its negotiations with Mr. Heyman and ISPH and their legal counsel, its review of the merger agreement and the factors it took into account in reaching its determination that the merger agreement is advisable, fair to and in the best interests of the unaffiliated stockholders of ISP. Based on the unanimous recommendation of the special committee, our board of directors has: o approved the merger agreement and the voting agreement; o determined that the merger and the merger agreement are substantively and procedurally fair to the unaffiliated stockholders of ISP; and o recommended that the stockholders of ISP vote to adopt the merger agreement. SPECIAL COMMITTEE'S POSITION AS TO FAIRNESS OF THE MERGER In reaching the conclusions described above, the special committee considered a number of factors, including the following factors, each of which, in the special committee's judgment supported its conclusion as to substantive fairness: o the proposed merger in which the stockholders of ISP, other than holders of common stock beneficially owned by Mr. Heyman, except shares held by qualified charitable organizations (which will be converted into the $10.30 per share merger consideration), would be entitled to receive $10.30 cash per share as merger consideration, a price the special committee viewed as attractive in light of ISP's historical and current financial performance and in light of general economic and stock market conditions; o the written opinion of Lehman Brothers to the special committee dated November 8, 2002, which was adopted by the special committee, a copy of which is attached to this proxy statement as Annex B, that, as of the date of the opinion and based upon and subject to the assumptions, limitations and qualifications set forth in that opinion, the merger consideration is fair, from a financial point of view, to the unaffiliated stockholders of ISP; o the special committee's belief, based on, among other things, the detailed financial and valuation advice provided to the special committee by its financial advisor, that the $10.30 per share merger consideration: o represented an attractive multiple of historical and projected earnings per share and cash flow per share; o was within the range of implied per share valuations based on comparable trading for non-controlled companies that Lehman Brothers, the special committee's financial advisor, deemed comparable to ISP; o compared favorably to an implied per share value based on the hypothetical performance of ISP stock assuming the announcement of Mr. Heyman's proposal, dated July 8, 2002 had not been made by applying the return of the Lehman Brothers Specialty Chemical Index from July 8, 2002 through November 4, 2002 to ISP's stock price of $7.95 the day prior to the announcement of the July 8, 2002 proposal letter; o was within the range of implied per share valuations based on recent full acquisitions as well as going-private transactions with a remaining minority interest of less than 50% and a remaining minority interest of less than 20%; and o was within the ranges of value produced by the discounted cash flow analysis based on ISP's Updated Projections; o the historical market prices of ISP's common stock and recent trading activity, including the substantial premiums implied by the $10.30 per share merger consideration of 29.6% and 48.8%, respectively, over ISP's stock prices one day and one month prior to the initial announcement of Mr. Heyman's proposal on July 8, 2002; 17 o that the increase in the market price of ISP's common stock following the initial proposal by Mr. Heyman may have reflected, in part, anticipation of a possible merger, rather than a higher intrinsic value for ISP common stock; o the presentations of Lehman Brothers regarding its financial analyses of the proposed merger. See "--Background of the Merger" above and "--Opinion of Lehman Brothers" below; o that the terms and conditions of the proposed merger were determined through lengthy negotiations between Mr. Heyman and his representatives and the special committee and its advisors, all of whom are unaffiliated with Mr. Heyman; o Mr. Heyman's controlling beneficial ownership interest in ISP and his unwillingness to cause ISP or his beneficial interest in ISP to be sold to a possible third party buyer, which suggested to the special committee that the proposed merger was an attractive alternative to the minority stockholders; o the availability of capital necessary to fund the merger consideration payable pursuant to the merger; o current difficult economic, industry and market conditions affecting ISP; and o that stockholders who do not waive their appraisal rights will have the opportunity in connection with the merger to demand appraisal of the fair value of their shares under Section 262 of the DGCL. The special committee also considered the following adverse factors associated with the merger: o that Lehman Brothers' analysis of industry transactions described in detail under "Opinion of Lehman Brothers" on page 24 had produced a range per share of $13.24 to $13.39. The special committee determined that this valuation depended to a considerable extent on the fact that the transactions analyzed each involved a full change of control, whereas the merger does not involve a change of control. Furthermore, each of the transactions analyzed had meaningful distinctions to the business, operations and financial conditions of ISP; o that because Mr. Heyman desired to retain his approximate 81% ownership interest in ISP and had indicated no intent to cause any portion of his beneficial interest in ISP to be offered for sale to a third party, public stockholders were not afforded an opportunity to participate in any control premium that might have been generated by the sale of the entire company to a third party; o that the public stockholders of ISP would have no ongoing equity participation in the surviving corporation following the merger, meaning that the public stockholders would cease to participate in ISP's future earnings or growth, if any, or to benefit from increases, if any, in the value of their ISP stock. o that there exists known and possible conflicts of interest of certain directors and executive officers of ISP discussed below in "--Interests of Directors and Executive Officers in the Merger." After considering each of the factors outlined above, the special committee concluded that the positive factors relating to the merger outweighed the negative factors. Because of the variety of factors considered, the special committee did not find it practicable to quantify or otherwise assign relative weights to, and did not make specific assessments of, the specific factors considered in reaching its determination. However, individual members of the special committee may have assigned different weights to various factors. The determination of the special committee was made after consideration of all of the factors together. The special committee also determined that the merger is procedurally fair because among other things: o the special committee consisted of directors that are not affiliated with Mr. Heyman and are not executive officers of ISP; o the special committee retained and was advised by independent legal counsel experienced in advising on similar transactions; o the special committee retained and was advised by Lehman Brothers Inc., an independent financial advisor, to assist in evaluating the proposed merger; o Lehman Brothers rendered an opinion concerning the fairness, from a financial point of view, of the consideration to be received by the unaffiliated holders of ISP common stock, which was adopted by the special committee; 18 o the proposed merger terms and conditions (including the majority of the minority condition), which were determined through lengthy negotiations between Mr. Heyman and his representatives and the special committee and its advisors, all of whom are unaffiliated with Mr. Heyman; o the nature and duration of the deliberations pursuant to which the special committee evaluated the proposed merger and alternatives the proposed merger; and o that the special committee is a mechanism well-established under Delaware law in transactions of this type. In its evaluation, the special committee did not ask Lehman Brothers to consider the liquidation or book values of ISP because it believed that those measures of asset value would be considerably less than the proposed merger consideration of $10.30 per share and ISP's going concern value. The special committee's belief regarding liquidation value was based upon the committee members knowledge of the specialty chemical industry and their belief that liquidation sales generally result in proceeds substantially less than the sale of a going concern business. While the special committee reviewed with Lehman Brothers its various financial analyses and ISP's historical and projected results, the special committee did not independently generate its own separate financial analysis of the merger. The special committee did not evaluate as alternatives to the proposed merger the possibility of a sale to a potential third party bidder due to Mr. Heyman's indicated unwillingness to cause his beneficial interest in ISP to be sold. Finally, the special committee believed that the merger consideration of $10.30 per share in cash was fair in relation to the going concern value per share based upon Lehman Brothers' financial analysis referred to in "--Opinion of Lehman Brothers" below. In reaching its determination, the special committee did not consider purchases by Mr. Heyman or ISPH of ISP stock during the past two years because, to the knowledge of the special committee, there were no purchases by Mr. Heyman or ISPH during that time. There were no firm offers made that the special committee is aware of by any unaffiliated person during the past two years for the merger, sale of a substantial portion of the assets of, or transaction resulting in the change of control of ISP. BOARD OF DIRECTORS' POSITION AS TO THE FAIRNESS OF THE MERGER In reaching the conclusions described above, the board of directors considered a number of factors, including the following factors, which, in the board's judgment, supported its conclusions as to substantive fairness: o the conclusions and recommendations of the special committee; and o the factors referred to above as having been taken into account by the special committee as to substantive fairness, including the receipt by the special committee of the opinion of Lehman Brothers that, as of the date of the opinion and based upon and subject to the assumptions, limitations and qualifications set forth in that opinion, the merger consideration is fair, from a financial point of view, to the unaffiliated stockholders of ISP. The board of directors also considered the adverse factors described above under "--Special Committee's Position as to Fairness of the Merger," including the fact that public stockholders were not afforded the opportunity to participate in a control premium because Mr. Heyman had no desire to cause any portion of his beneficial interest in ISP to be sold to a third party. The board of directors also considered the conflicts of interest of certain directors and executive officers of ISP discussed below in "--Interests of Directors and Executive Officers in the Merger." In concluding that the merger is procedurally fair, the board of directors considered a number of factors, including the following factors, which, in the board's judgment, supported its conclusions as to procedural fairness: o the conclusions and recommendations of the special committee; o the fact that the special committee unanimously determined that the merger agreement is advisable, fair to and in the best interest of the unaffiliated stockholders of ISP; o the engagement by the special committee of independent legal and financial advisors; and o the fact that the merger agreement contains the majority of the minority condition. In considering the conclusions and the recommendations of the special committee, the board of directors believed that the analysis of the special committee was reasonable and adopted the special committee's analysis underlying the special committee's conclusions. 19 MR. HEYMAN AND ISPH'S POSITIONS AS TO THE FAIRNESS OF THE MERGER The rules of the Securities and Exchange Commission require Mr. Heyman and ISPH to express their belief as to the fairness of the merger to the unaffiliated holders of ISP common stock. Mr. Heyman and ISPH believe that the merger is substantively and procedurally fair to the unaffiliated holders of ISP common stock. However, neither Mr. Heyman nor ISPH has performed, or engaged a financial advisor to perform, any valuation analysis for the purposes of assessing the fairness of the merger to the unaffiliated holders of ISP common stock. Moreover, neither Mr. Heyman nor ISPH participated in the deliberations of the special committee or received advice from the special committee's financial advisor. Mr. Heyman and ISPH's belief that the merger is substantively fair to the unaffiliated holders of ISP common stock is based on the following factors: o the fact that the special committee concluded that the merger is advisable, fair to, and in the best interests of the unaffiliated holders of ISP's common stock (although Mr. Heyman and ISPH did not rely upon the special committee's analysis); o the fact that the special committee received a written opinion from Lehman Brothers dated November 8, 2002 as to the fairness, from a financial point of view, of the $10.30 per share cash merger consideration; o the consideration to be paid in the merger represents a nearly 30% premium over the reported closing price of ISP common stock on the New York Stock Exchange on the last trading day prior to the announcement of Mr. Heyman's proposal on July 8, 2002, and nearly a 49% premium over the average closing price for the 30 days prior to the announcement of the proposal; o the S&P 500 Index and the S&P Midcap Specialty Chemicals Index declined 5.5% and 9.3%, respectively, during the period from July 8, 2002 through November 6, 2002, the date on which the special committee agreed to recommend the merger agreement, thereby indicating that the premium of the merger consideration over the unaffected share price of ISP (i.e., the market price that would likely be in effect in absence of the merger proposal) would likely have been higher than the premium referred to above; o Mr. Heyman and ISPH's belief that the merger consideration is fair in relation to the going concern value per share of ISP (although they did not calculate a specific going concern value per share, Mr. Heyman and ISPH believe that the merger consideration is fair in relation to the going concern value per share based upon (1) their knowledge of ISP's business and prospects, (2) the projections contained in this proxy statement, including the assumptions contained therein, (3) ISP's historical results of operations and (4) their general knowledge of the specialty chemical industry; o the merger will provide consideration to ISP's stockholders entirely in cash and is not subject to any financing condition; and o the merger would shift the risk of the future financial performance of ISP from the public stockholders, who do not have the power to control decisions made as to ISP's business, entirely to Mr. Heyman, who has the power to control ISP's business. 20 Mr. Heyman and ISPH considered each of the foregoing factors to support their determinations as to the fairness of the merger. Mr. Heyman and ISPH did not consider any other material factors in evaluating the substantive fairness of the merger to the unaffiliated holders of ISP common stock. In light of the fact that Mr. Heyman was unwilling to cause his beneficial interest in ISP to be sold, Mr. Heyman and ISPH did not consider a possible sale to a third party as an alternative to the proposed merger. As a result, Mr. Heyman and ISPH did not evaluate the prices potentially attainable in other transactions in which he would sell control of ISP. Neither Mr. Heyman nor ISPH found it practicable to assign, nor did they assign, relative weights to the individual factors considered in reaching their conclusion as to fairness. Mr. Heyman and ISPH did not consider whether the merger consideration constitutes fair value in relation to the liquidation value of ISP and gave little consideration to the book value of ISP, because they believed that those measures of asset value were not relevant to the market value of ISP's business and that liquidation valuations result in lower valuations of leveraged manufacturing companies. In addition, the liquidation of ISP's assets was not considered to be a viable course of action because substantial value results from continuing ISP as a going-concern and any liquidation would destroy that value. Therefore, no appraisal of liquidation value was sought for purposes of valuing the shares of ISP common stock. Also, Mr. Heyman and ISPH believe that book value is a valuation methodology more typically used in the banking, utilities, real estate and financial services industries. Nonetheless, Mr. Heyman and ISPH note that the net book value per share of ISP, as of June 30, 2002, was $7.85 and the net book value per share of ISP, as of September 30, 2002 was $8.14. The merger consideration represents a premium of nearly 31% over the June 30, 2002 net book value per share and 27% over the September 30, 2002 net book value per share. Mr. Heyman and ISPH's belief that the merger is procedurally fair to the unaffiliated holders of ISP common stock is based on the following factors: o the merger and the terms and conditions of the merger agreement were the result of good faith negotiations between the special committee and Mr. Heyman and their respective advisors and representatives; o the special committee retained Lehman Brothers, which is not affiliated with Mr. Heyman or ISPH management, to serve as its independent financial advisor, and the special committee received an opinion from Lehman Brothers on November 6, 2002 (subsequently confirmed in writing on November 8, 2002) to the effect that as of such date and, based upon and subject to, the assumptions, limitations and qualifications set forth in its written opinion, the $10.30 in cash per share merger consideration was fair from a financial point of view to ISP's unaffiliated stockholders; o the merger was approved by each member of ISP's board of directors, other than Mr. Heyman and Mr. Kumar (each of whom abstained because they are also directors of ISPH); and o the fact that stockholders who do not vote to adopt the merger agreement would be entitled, subject to compliance with certain statutorily required procedures to exercise appraisal rights pursuant to Section 262 of the DGCL, which allows stockholders to have the fair value of their shares determined by the Court of Chancery of the State of Delaware and paid to them in cash. Neither Mr. Heyman nor ISPH made any purchases of ISP common stock during the last two years and, therefore, did not compare the merger consideration to any recent prices paid by them for ISP common stock. In addition, neither Mr. Heyman nor ISPH is aware of any offer made during the last two years to acquire ISP, thus no comparison of the merger consideration could be made to any other comparable offer. The foregoing discussion of the information and factors considered and given weight by Mr. Heyman and ISPH is not intended to be exhaustive, but is believed to include all material factors considered by Mr. Heyman and ISPH. The view of Mr. Heyman and ISPH as to the fairness of the merger is not a recommendation to any stockholder as to how that stockholder should vote on the merger. OPINION OF LEHMAN BROTHERS In August 2002, the special committee engaged Lehman Brothers to act as its financial advisor with respect to Mr. Heyman's July 8, 2002 proposal to acquire the remaining shares of ISP not already beneficially owned by him and his affiliates. On November 6, 2002, Lehman Brothers rendered its oral opinion (subsequently confirmed in writing on November 8, 2002) to the special committee that as of that date and based upon and subject to the assumptions, limitations and qualifications set forth in that opinion, the consideration offered in the merger to the unaffiliated stockholders of ISP is fair, from a financial point of view, to those stockholders. 21 THE FULL TEXT OF LEHMAN BROTHERS' WRITTEN OPINION DATED NOVEMBER 8, 2002 IS ATTACHED AS ANNEX B TO THIS PROXY STATEMENT. STOCKHOLDERS SHOULD READ THAT OPINION FOR A DISCUSSION OF THE ASSUMPTIONS MADE, PROCEDURES FOLLOWED, FACTORS CONSIDERED AND LIMITATIONS UPON THE REVIEW UNDERTAKEN BY LEHMAN BROTHERS IN RENDERING ITS OPINION. THE FOLLOWING IS A SUMMARY OF THAT OPINION AND THE METHODOLOGY THAT LEHMAN BROTHERS USED TO RENDER ITS FAIRNESS OPINION. Lehman Brothers' advisory services and Lehman Brothers' opinion were provided for the information and assistance of the special committee in connection with its consideration of the merger agreement and the merger. Lehman Brothers' opinion is not intended to be and does not constitute a recommendation to any stockholder of ISP as to how such stockholder should vote with respect to the merger. Lehman Brothers was not requested to opine as to, and its opinion does not address, ISP's underlying business decision to proceed with or effect the merger. In arriving at its opinion, Lehman Brothers reviewed and analyzed: o the merger agreement and the specific terms of the merger; o publicly available information concerning ISP that Lehman Brothers believed to be relevant to its analysis, including ISP's annual report on Form 10-K for the fiscal year ended December 31, 2001, ISP's quarterly reports on Form 10-Q for the quarters ended March 31 and June 30, 2002, and the amended Schedule 13D filed by Mr. Heyman on July 9, 2002; o financial and operating information with respect to the business, operations and prospects of ISP furnished to Lehman Brothers by ISP, including, without limitation, the Five-Year Plan provided to Lehman Brothers on September 3, 2002 and the Updated Projections provided to Lehman Brothers and the special committee on October 21, 2002, which were updated and lower projections of future financial performance of ISP prepared by management of ISP; o a trading history of ISP's common stock from June 25, 1991 to November 4, 2002 and a comparison of that trading history with those of other companies that Lehman Brothers deemed relevant; o a comparison of the historical financial results and present financial condition of ISP with those of other companies that Lehman Brothers deemed relevant; and o a comparison of the financial terms of the merger with the financial terms of certain other recent transactions that Lehman Brothers deemed relevant. In addition, Lehman Brothers had discussions with the management of ISP concerning its business, operations, assets, financial condition and prospects and undertook such other studies, analyses and investigations as Lehman Brothers deemed appropriate. In arriving at its opinion, Lehman Brothers assumed and relied upon the accuracy and completeness of the financial and other information used by Lehman Brothers without assuming any responsibility for independent verification of that information and further relied upon the assurances of management of ISP that they were not aware of any facts or circumstances that would make that information inaccurate or misleading. With respect to the financial projections of ISP, Lehman Brothers was advised by ISP that the Updated Projections were reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of ISP as to the future financial performance of ISP and, accordingly, Lehman Brothers assumed that ISP would perform substantially in accordance with those projections. Furthermore, Lehman Brothers discussed the Updated Projections with the management of ISP and the special committee, and it was agreed that the Updated Projections were the appropriate projections to use in performing Lehman Brothers' analysis. In arriving at its opinion, Lehman Brothers did not conduct a physical inspection of the properties and facilities of ISP and did not make or obtain any evaluations or appraisals of the assets or liabilities of ISP. In addition, the special committee did not authorize Lehman Brothers to solicit, and Lehman Brothers did not solicit, any indications of interest from any third party with respect to the purchase of all or a part of ISP's business. Furthermore, based on advice of the management of ISP, Lehman Brothers understood that Mr. Heyman does not currently intend to cause his beneficial interest in ISP to be sold (other than as permitted pursuant to the terms of the voting agreement between Mr. Heyman and ISP) or to solicit or entertain any proposals from third parties for the acquisition of ISP as, or substantially as, an entirety. Lehman Brothers' opinion was necessarily based upon market, economic and other conditions as they existed on, and could be evaluated as of, the date of the opinion. In connection with rendering its opinion, Lehman Brothers performed certain financial, comparative and other analyses as described below. The preparation of a fairness opinion involves various determinations as to the most appropriate and relevant methods of financial and comparative analysis and the application of those methods to the particular circumstances, and therefore, is not readily susceptible to summary description. Furthermore, in arriving at its opinion, Lehman Brothers considered 22 the results of all of its analyses and did not attribute any particular weight to any analysis or factor considered by it. Accordingly, Lehman Brothers believes that its analyses must be considered as a whole and that considering any portion of those analyses and factors, without considering all analyses and factors as a whole, could create a misleading or incomplete view of the process underlying its opinion. In its analyses, Lehman Brothers made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of ISP. None of ISP, Lehman Brothers or any other person assumes responsibility if future results are materially different from those discussed. Any estimates contained in these analyses are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than as set forth in the estimates. In addition, analyses relating to the value of businesses do not purport to be appraisals or to reflect the prices at which businesses actually may be sold. The following is a summary of the material financial analyses used by Lehman Brothers in connection with providing its opinion to the special committee. In arriving at its opinion, Lehman Brothers did not ascribe a specific range of value to ISP, but rather made its determination as to the fairness, from a financial point of view, to the unaffiliated stockholders of ISP of the consideration offered to such stockholders in the merger on the basis of the financial and comparative analyses described below. Certain of the summaries of financial analyses include information presented in tabular format. In order to fully understand the financial analyses used by Lehman Brothers, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Accordingly, the analyses listed in the tables and described below must be considered as a whole. Considering any portion of those analyses and of the factors considered, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying Lehman Brothers' opinion. STOCK TRADING HISTORY Lehman Brothers considered historical data with regard to the trading prices of ISP common stock for the period from June 25, 1991 to November 4, 2002 and the relative stock price performances during this same period for ISP, the Lehman Brothers Specialty Chemicals Index, or LBSCI, and the Standard & Poor's 500 Index. During the year prior to announcement of Mr. Heyman's July 8, 2002 cash proposal of $10.00 per share, the closing stock price of ISP ranged from $5.60 to $11.11 per share. Over this approximate one-year period, ISP stock provided a negative return of 25.4%, while the LBSCI provided a negative return of 18.5% and the S&P 500 Index provided a return of 11.5%. As such, ISP underperformed the LBSCI over this period by 6.9% and underperformed the S&P 500 Index over this period by 36.9%. During the year prior to November 4, 2002, the closing stock price of ISP ranged from $5.60 to $10.45 per share. The following table summarizes the historical prices one year prior to November 4, 2002 and one year prior to the announcement, as well as the corresponding premium of the merger consideration to each of these price statistics: PRIOR TO NOVEMBER 4, 2002 PRIOR TO JULY 8, 2002 ANNOUNCEMENT(1) ---------------------------------- ------------------------------------- ISP PRICE % PREMIUM ISP PRICE % PREMIUM --------- --------- --------- --------- Merger Consideration $10.30 NA $10.30 NA 1 Day 9.20 12.0% 7.95 29.6% 7 Days Avg. 9.16 12.5% 7.82 31.7% 30 Days Avg. 9.26 11.2% 6.92 48.8% 60 Days Avg. 9.44 9.2% 7.70 33.7% 90 Days Avg. 9.59 7.4% 8.32 23.8% 180 Days Avg. 9.03 14.0% 8.61 19.7% 1 Year Avg. 8.98 14.7% 8.85 16.4% 1 Year Median 9.17 12.3% 8.80 17.0% 1 Year High 10.45 (1.4%) 11.11 (7.3%) 1 Year Low 5.60 83.9% 5.60 83.9% ----------------- (1) The "1 Day" trading date prior to announcement was July 8, 2002. 23 COMPARABLE TRADING ANALYSIS In order to assess how the public market values shares of non-controlled, fully distributed publicly traded companies with similar operating characteristics as ISP, Lehman Brothers reviewed and compared specific financial and operating data relating to ISP with selected companies that Lehman Brothers deemed comparable to ISP. Lehman Brothers chose the companies used in the comparable trading analysis based on their similarity to ISP in the mix and characteristics of their businesses, growth, returns and margins. These companies consisted of: o Albemarle Corp., o Arch Chemicals Inc., o Cambrex Corp., o Croda International PLC, o Cytec Industries Inc., o Great Lakes Chemical Corp., o International Flavors & Fragrances Inc., o Penford Corp., and o Sensient Technologies Corp. Using publicly available information, Lehman Brothers calculated and analyzed each company's enterprise value relative to certain historical and projected financial criteria such as sales, earnings before interest, taxes, depreciation and amortization (EBITDA) and earnings before interest and taxes (EBIT). The enterprise value of each company was obtained by adding its short-term and long-term debt to the sum of the market value of its common equity, the value of any preferred stock (at liquidation value) and the book value of any minority interest, and subtracting its cash and cash equivalents. The analysis indicated the following multiples as of November 4, 2002: COMPARABLE COMPANIES ----------------------------------------------------- ISP AT HIGH MEAN LOW TRANSACTION --------- --------- --------- ----------- Enterprise Value as a Multiple of: LTM(1) Sales 2.36x 1.38x 0.66x 1.38x 2002E Sales 2.37x 1.35x 0.85x 1.35x 2003E Sales 2.31x 1.27x 0.85x 1.35x LTM EBITDA 12.8x 7.6x 5.6x 6.8x 2002E EBITDA 10.2x 7.3x 5.4x 6.7x 2003E EBITDA 9.4x 6.8x 5.2x 6.9x LTM EBIT 43.6x 12.1x 10.3x 10.2x 2002E EBIT 14.7x 11.7x 10.8x 10.1x 2003E EBIT 12.0x 10.5x 10.2x 10.6x -------------- (1) LTM means the latest twelve months ending June 30, 2002 for ISP and for other comparable companies except as of May 31, 2002 for Penford Corp. and as of December 31, 2001 for Croda International PLC. Due to the inherent differences between the business, operations and prospects of ISP and the business, operations and prospects of the companies included in the comparable companies, Lehman Brothers believed that it was inappropriate to, and therefore did not, rely solely on the quantitative results of the comparable trading analysis and accordingly also made qualitative judgments concerning differences between the financial and operating characteristics and prospects of ISP and the companies included in the comparable trading analysis that would affect the public trading values of each. Accordingly, using the mean multiples as a general guide, Lehman Brothers selected certain multiples that it believed reflected the theoretical trading multiples for ISP on a non-controlled, fully distributed basis. Based on those multiples, this analysis indicated a range of equity values per share of $10.07 to $12.67. Lehman Brothers noted that the merger consideration of $10.30 per share falls within this range. 24 INDUSTRY TRANSACTION ANALYSIS Using publicly available information, Lehman Brothers reviewed and compared the purchase prices and multiples paid in 11 acquisitions of companies that Lehman Brothers deemed relevant to arriving at its opinion. Lehman Brothers chose the transactions used in the industry transaction analysis, based on the similarity of the target companies in the transactions to ISP in the mix and characteristics of their businesses, growth, returns and margins. o Acquisition of Roche Vitamins and Fine Chemicals by DSM NV, o Acquisition of Haarmann & Reimer (Bayer AG) by EQT Northern Europe Private Equity Fund, o Acquisition of Cognis BV (Henkel KGaA) by an Investor Group, o Acquisition of Ascot PLC by Dow Chemical Co., o Acquisition of Laporte PLC by Degussa AG, o Acquisition of BF Goodrich Performance Materials by AEA Investors, o Acquisition of Catalytica Pharmaceuticals (Catalytica Inc.) by DSM NV, o Acquisition of Hickson International PLC by Arch Chemicals Inc., o Acquisition of Witco Corp. by Crompton & Knowles Corp., o Acquisition of Zeneca Specialties (Astra Zeneca PLC) by Cinven and Investcorp, and o Acquisition of Bio Whittaker Inc. by Cambrex Corp. Lehman Brothers considered the transaction values as multiples of LTM sales, EBITDA and EBIT for the four fiscal quarters immediately preceding the announcement of each applicable transaction. The analysis indicated the following multiples: COMPARABLE TRANSACTIONS ------------------------------------------------ ISP AT HIGH MEAN LOW TRANSACTION --------- --------- --------- ----------- Transaction Value as a Multiple of: LTM Sales 2.64x 1.57x 0.59x 1.38x LTM EBITDA 10.5x 8.6x 6.4x 6.8x LTM EBIT 17.4x 14.0x 10.3x 10.2x Because the reasons for and the circumstances surrounding each of the transactions analyzed were so diverse and because of the inherent differences in the businesses, operations, financial conditions and prospects of ISP, and the businesses, operations, and financial conditions of the companies included in the industry transactions group, Lehman Brothers believed that a purely quantitative comparable transaction analysis would not be particularly meaningful in the context of the merger. Lehman Brothers believed that the appropriate use of an industry transaction analysis in this instance involves qualitative judgments concerning the differences between the characteristics of these transactions and the merger which would affect the acquisition values of the acquired companies and ISP. Lehman Brothers also noted that the industry transactions all involved a full change of control whereas the merger does not involve a change of control. Using the mean multiples as a general guide, Lehman Brothers selected certain multiples that it believed reflected the theoretical transaction multiples for ISP on a full change in control basis. Based on those multiples, this analysis indicated a range of equity values per share of $13.24 to $13.39. PURCHASE PRICE RATIO ANALYSIS Lehman Brothers reviewed for the special committee its purchase price ratio analysis. The purchase price ratio analysis provides enterprise value multiples of key operating statistics for the implied transaction valuations based on (i) the $7.95 closing price of ISP common stock on July 8, 2002 (the day prior to the announcement of Mr. Heyman's proposal), (ii) the original $10.00 per share proposal and (iii) the revised $10.30 per share proposal. Based on each of these stock prices, Lehman Brothers calculated the ratio of ISP's enterprise value to its forecasted annual EBITDA and EBIT. Lehman Brothers calculated enterprise value by adding ISP's short and long-term debt and certain non-operating liabilities to the equity value implied by the specified share prices, and then subtracted the amount of ISP's cash and cash equivalents and the net value of its investment portfolio. 25 The original $10.00 and revised $10.30 per share proposals represented premiums to the pre-announcement share price of $7.95 of 25.8% and 29.6%, respectively. ISP's implied enterprise value, based on the original $10.00 proposal, represented multiples of 6.6x and 9.9x over estimated 2002 EBITDA and 2002 EBIT, respectively, and 6.8x and 10.5x over estimated 2003 EBITDA and 2003 EBIT, respectively. The corresponding multiples based on the $10.30 per share proposal were 6.7x and 10.1x for 2002 and 6.9x and 10.6x for 2003. In calculating the multiples, Lehman Brothers used the Updated Projections. The purchase price ratio analysis enabled Lehman Brothers to compare the multiples implied by the merger consideration with (i) the pre-announcement trading level of ISP common stock, (ii) the current trading levels of companies that Lehman Brothers deemed comparable to ISP, as described in "--Comparable Company Analysis," and (iii) the multiples of those metrics paid in similar transactions, as detailed in "--Industry Transaction Analysis." TRANSACTION PREMIA ANALYSIS Lehman Brothers reviewed the premia paid for 30 selected going private transactions since 1998, where (i) cash was used as consideration, (ii) the remaining minority interest was less than 50%, and (iii) the transaction value was greater than $100 million. Lehman Brothers calculated the premium per share paid by the acquiror for each respective deal, as compared to the average share price of the target company's common stock one day, 7 calendar days, 30 calendar days and 90 calendar days prior to the public announcement of each selected transaction. The analysis produced the following premia ranges: PREMIA PAID OVER AVERAGE PRICE FOR: ---------------------------------------------------------------------- 1 DAY 7 DAYS 30 DAYS 90 DAYS --------- --------- --------- ----------- Low: 9.9% 13.2% 13.1% 13.5% High: 140.0% 136.9% 113.3% 116.0% Mean: 46.4% 47.7% 49.2% 42.2% Median: 42.6% 43.4% 48.6% 36.2% Company Share Price Data: $7.95 $7.82 $6.92 $8.32 Merger Consideration ($10.30): 29.6% 31.7% 48.8% 23.8% Based on the median and mean data, this analysis indicated a range of equity values per share of $10.29 to $11.34 and $10.33 to $11.83, respectively. Lehman Brothers noted that the merger consideration of $10.30 falls within the range based on the median data and below the range based on the mean data. Lehman Brothers also reviewed the premia paid for 19 selected going private transactions since 1992, where (i) cash was used as consideration, (ii) the remaining minority interest was less than 20%, and (iii) the transaction value was greater than $100 million. Lehman Brothers calculated the premium per share paid by the acquiror for each respective deal, as compared to the average share price of the target company's common stock one day, 7 calendar days, 30 calendar days and 90 calendar days prior to the announcement of each selected transaction. The analysis produced the following premia ranges: PREMIA PAID OVER AVERAGE PRICE FOR: ---------------------------------------------------------------------- 1 DAY 7 DAYS 30 DAYS 90 DAYS --------- --------- --------- ----------- Low: 9.9% 13.2% 13.1% 9.0% High: 140.0% 122.7% 95.7% 73.4% Mean: 40.8% 40.8% 44.3% 40.0% Median: 43.5% 41.2% 42.9% 39.9% Company Share Price Data: $7.95 $7.82 $6.92 $8.32 Merger Consideration ($10.30): 29.6% 31.7% 48.8% 23.8% Based upon the median and mean data, this analysis indicated a range of equity values per share of $9.89 to $11.64 and $9.99 to $11.65, respectively. Lehman Brothers noted that the merger consideration of $10.30 falls within both of these ranges. Lehman Brothers also reviewed the hypothetical performance of ISP stock had the announcement of the proposal letter, dated July 8, 2002, from Mr. Heyman not been made on July 8, 2002 by applying the return of the LBSCI from July 8, 2002 through November 4, 2002 to ISP's stock price of $7.95 the day prior to the announcement of the July 8, 2002 proposal letter. Over this period, the LBSCI provided a negative return of 11.0%, implying a hypothetical "unaffected" price of $7.07 per share of ISP on November 4, 2002 had the announcement not been made. Lehman Brothers then applied the mean and 26 median 1-day premia of the two data sets described above to the hypothetical "unaffected" ISP stock price at November 4, 2002. This analysis indicated a range of equity values per share of $9.96 to $10.35. Lehman Brothers noted that the merger consideration of $10.30 falls within this range. Additionally, Lehman Brothers reviewed the premia paid for 60 selected full acquisitions since 2000 that did not constitute going private transactions, where (i) cash was used as consideration, (ii) the target company was not classified as a financial services or technology company, and (iii) the transaction value was greater than $100 million. Lehman Brothers calculated the premium per share paid by the acquiror for each respective deal, as compared to the average share price of the target company's common stock one day, 7 calendar days, 30 calendar days and 90 calendar days prior to the announcement of each selected transaction. The analysis produced the following premia ranges: PREMIA PAID OVER AVERAGE PRICE FOR: ------------------------------------------------------------------ 1 DAY 7 DAYS 30 DAYS 90 DAYS --------- --------- --------- ----------- Low: (7.8%) (7.4%) (3.4%) (9.1%) High: 540.0% 519.4% 411.7% 267.7% Mean: 44.1% 45.6% 48.1% 51.7% Median: 28.8% 31.7% 33.5% 37.6% Company Share Price Data: $7.95 $7.82 $6.92 $8.32 Merger Consideration ($10.30): 29.6% 31.7% 48.8% 23.8% Based upon the median and mean data, this analysis indicated a range of equity values per share of $9.24 to $11.45 and $10.26 to $12.62, respectively. Lehman Brothers noted that the merger consideration of $10.30 falls within both of these ranges. DISCOUNTED CASH FLOW ANALYSIS Lehman Brothers performed a discounted cash flow analysis on the projected financial information of ISP for the fiscal years 2003 through 2007 based upon the Updated Projections through 2006 and extrapolated financial results for 2007 based upon operating and financial assumptions, forecasts and other information provided to Lehman Brothers by the management of ISP. Using this information, Lehman Brothers discounted to present (December 31, 2002) value the projected stream of unlevered net income (earnings before interest and after taxes) for the fiscal years 2003 to 2007 as adjusted for (1) certain projected non-cash items (such as depreciation and amortization); (2) forecasted capital expenditures; and (3) forecasted working capital adjustments. To estimate the residual value of ISP at the end of the forecast period ("Terminal Value") Lehman Brothers applied a range of 3.0% to 5.0% perpetuity growth rates to projected fiscal 2007 free cash flow. Lehman Brothers also estimated the Terminal Value by applying a range of 6.7x to 8.0x multiples to projected fiscal 2007 EBITDA. Lehman Brothers used after tax discount rates of 9% to 11%. Based on these discount rates and a selected range of terminal values, Lehman Brothers calculated the implied equity value per share at approximately $8.11 to $14.02. Lehman Brothers noted that the merger consideration of $10.30 falls within this range. Lehman Brothers performed a similar discounted cash flow analysis with regard to the projected financial information for ISP based on the Five-Year Plan. This analysis resulted in an implied equity value per share of approximately $10.90 to $18.03. Lehman Brothers is an internationally recognized investment banking firm and, as part of its investment banking activities, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive bids, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. The special committee selected Lehman Brothers because of its expertise, reputation and familiarity with ISP and the chemicals industry generally, and because its investment banking professionals have substantial experience in transactions comparable to the merger. As compensation for its services in connection with the merger, ISP paid Lehman Brothers $1.4 million, which was not contingent upon either the execution of the merger agreement or consummation of the merger. In addition, ISP has agreed to reimburse Lehman Brothers for reasonable out-of-pocket expenses incurred in connection with its engagement and to indemnify Lehman Brothers and related persons for certain liabilities that may arise out of its engagement by the special committee and the rendering of its fairness opinion. 27 IN THE ORDINARY COURSE OF ITS BUSINESS, LEHMAN BROTHERS MAY ACTIVELY TRADE IN THE DEBT OR EQUITY SECURITIES OF ISP AND ITS SUBSIDIARIES FOR ITS OWN ACCOUNT AND FOR THE ACCOUNTS OF ITS CUSTOMERS AND, ACCORDINGLY, MAY AT ANY TIME HOLD A LONG OR SHORT POSITION IN SUCH SECURITIES. ISP'S FORECASTS ISP does not, as a matter of course, publicly disclose forecasts as to future revenues or earnings. However, ISP management did prepare forecasts which were provided to Mr. Heyman in his capacity as Chairman of ISP's board of directors and Lehman Brothers in connection with its financial analysis of ISP and the merger proposal. The forecasts are included in this proxy statement only because ISP provided that information to Lehman Brothers and Lehman Brothers used the data in connection with its fairness opinion and related presentation to the special committee and because Mr. Heyman had access to that data. See "--Opinion of Lehman Brothers." ISP's forecasts were not prepared with a view to public disclosure. ISP expects actual and forecasted results to differ, and actual results may be materially different than those set forth below. ISP did not prepare the forecasts with a view to complying with the published guidelines of the Securities and Exchange Commission regarding forecasts, and ISP did not prepare the forecasts in accordance with the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of financial forecasts. The projected financial information set forth below has been prepared by and is the responsibility of ISP's management. Moreover, ISP's independent auditors have not examined, compiled, or applied any procedures to, the forecasts in accordance with standards established by the American Institute of Certified Public Accountants and express no opinion or any assurance on their reasonableness, accuracy or achievability. The projected financial data set forth below constitute forward-looking statements. It is not possible to predict whether the assumptions made in preparing the forecasts will be valid, and ISP cautions stockholders that any such forward-looking statements are not guarantees of future performance. ISP cannot assure you that these forecasts will be realized, and actual results may be materially more or less favorable than those contained in the forecasts set forth below. Investors should consider the risks and uncertainties in our business that may affect future performance and that are discussed under "Special Note Regarding Forward-Looking Statements" and in the documents incorporated by reference in this proxy statement. ISP's inclusion of the forecasts should not be regarded as an indication that ISP, the special committee, the board of directors, Mr. Heyman, ISPH or Lehman Brothers considered or consider the forecasts to be a reliable prediction of future events, and the forecasts should not be relied upon as such. To the extent that these forecasts represent ISP management's best estimate of possible future performance, this estimate is made only as of the date of the forecasts and not as of any later date. In particular, the projections for 2003-2006 included in the Five-Year Plan were prepared in December 2001 and have been superseded by the Updated Projections. ISP does not intend to update, revise or correct these forecasts if they become inaccurate. Stockholders should take this into account when evaluating any factors or analyses based on ISP's forecasts. 28 As discussed above, on September 3, 2002 ISP's management provided Lehman Brothers with the Five-Year Plan. The Five-Year Plan was prepared in December 2001 for presentation to ISP's board of directors in April 2002. Prior to delivering the Five-Year Plan to Lehman Brothers, management reviewed ISP's financial performance (excluding ISP's investment activities) for the first six months of 2002 and revised the 2002 full-year projections contained in the Five-Year Plan, but did not undertake to update or confirm the projections for years 2003-2006. Therefore, the projections in the Five-Year Plan for the 2002 year were made as of September 3, 2002, but the 2003-2006 projections in the Five-Year Plan were made as of December 2001. The projections of net sales and operating income contained in the Five-Year Plan (as adjusted) are set forth below: FIVE-YEAR PLAN --------------------------------------------------------------------- FISCAL YEARS ENDED DECEMBER 31, --------------------------------------------------------------------- 2002 (1) 2003 2004 2005 2006 ---------- --------- --------- --------- --------- ($ in millions) NET SALES: Personal Care......................... $207.7 $218.5 $227.8 $237.3 $248.2 Pharmaceutical, Food and Beverage........................... 247.3 254.8 270.4 286.7 305.0 Performance Chemicals, Fine Chemicals and Industrial........... 304.1 275.5 284.4 292.5 301.4 --------- -------- -------- -------- -------- Total Specialty Chemicals.......... 759.1 748.8 782.6 816.5 854.6 Mineral Products...................... 92.9 93.5 98.0 100.0 102.4 --------- -------- -------- -------- -------- Total.............................. $852.1 $842.3 $880.6 $916.5 $957.0 ========= ======== ======== ======== ======== OPERATING INCOME:(2) Personal Care......................... $ 33.1 $ 47.0 $ 49.6 $ 52.3 $ 54.2 Pharmaceutical, Food and Beverage........................... 59.6 62.3 66.8 71.6 75.4 Performance Chemicals, Fine Chemicals and Industrial........... 8.4 1.1 4.6 8.5 11.9 --------- -------- -------- -------- -------- Total Specialty Chemicals.......... 101.1 110.4 121.0 132.4 141.5 Mineral Products...................... 19.8 19.3 20.0 20.5 20.6 --------- -------- -------- -------- -------- Total.............................. $120.9 $129.7 $141.0 $152.9 $162.1 ========= ======== ======== ======== ======== ------------- (1) Updated September 3, 2002 The forecasts from the original Five-Year Plan prepared December 2001 projected net sales for 2002 of $821.4 million and operating income for 2002 of $120.7 million.

(2) Excludes investment income and loss. 29 For the reasons described under "--Background of the Merger," in October 2002, ISP's management updated the projections reflected in the Five-Year Plan for developments occurring after December 2001 and provided those Updated Projections to Lehman Brothers on October 10, 2002 and again to Lehman Brothers and the special committee on October 21, 2002. The Updated Projections took into account changes in circumstances -- primarily substantially greater than anticipated pricing pressures in ISP's core chemicals and minerals businesses -- since the preparation in the Five-Year Plan and represented ISP management's estimates of future financial performance (excluding ISP's investment activities) for the years 2002 through 2006, as of October 10, 2002 and October 21, 2002.

REASONS FOR THE MERGER; PURPOSE AND STRUCTURE OF THE MERGER The purpose of the merger is to permit holders of ISP's common stock to realize a significant cash premium to ISP's historical market prices for their shares and for Mr. Heyman to increase his equity ownership interest in ISP from approximately 81% to 100%. Mr. Heyman decided to pursue the merger at this time for a number of reasons. First, Mr. Heyman believes that ISP has been unable to realize some of the primary anticipated benefits of having publicly traded equity securities. For example, as a result of ISP's small public float, ISP has been unable to utilize the ISP common stock as a currency for acquisitions. In addition, the lack of appreciation of the ISP common stock has impaired ISP's ability to use stock options and other equity-based incentives as a meaningful tool to attract and retain employees. Moreover, Mr. Heyman believes that the near- and medium-term prospects of increasing ISP stockholder value are unfavorable for a number of reasons. Attracting public investors to a company with a majority stockholder and a small public float is inherently difficult and has been made more difficult by the general stock market downturn. In addition, Mr. Heyman believes that the volatility of ISP's earnings as a result of its substantial portfolio of investment securities has negatively impacted and will likely continue to negatively impact ISP's stock performance in the public market. 30 Mr. Heyman seeks to improve ISP's operating performance by increasing management's flexibility to take actions without the constraints imposed by the public market. Mr. Heyman believes that without the constraints of the public market, and in particular the market's emphasis on quarterly earnings, ISP's management will have greater flexibility to effectively manage ISP's assets and to make decisions that may negatively impact quarterly earnings, but that may increase the value of ISP's assets or earnings over the long term. In a public company setting, decisions that negatively affect quarterly earnings could significantly reduce ISP's share price. Mr. Heyman also seeks to permit ISP to eliminate the costs and administrative burdens of being a public company. Finally, following the merger, ISP will no longer be subject to the reporting requirements of the Securities Exchange Act of 1934, which will allow ISP to eliminate the costs of preparing, printing and mailing certain corporate reports and proxy statements. In addition, "going private" will allow ISP to eliminate certain other costs and functions associated with being a public company, including certain legal and accounting costs, the costs of maintaining a transfer agent and the costs of investor relations activities. The elimination of the foregoing requirements will also eliminate the time devoted by employees and members of ISP's management to those activities, thereby providing more freedom to focus on ISP's business and operations. Mr. Heyman has considered certain alternatives to the merger, including having ISP remain public without acquiring additional shares or pursuing a public offering to increase the liquidity of the public trading market for the ISP common stock. However, in light of capital market conditions and the reluctance of institutional investors to purchase stock of a company with a small public float, ISP concluded that such an offering could not be effected on terms that were economically attractive. In addition, as noted in "--Background of the Merger," Mr. Heyman considered the possibility of pursuing a going private transaction by means of a tender offer rather than a merger, but ultimately concluded that the merger constituted a preferable means of effecting the proposed transaction. As discussed in "--Background of the Merger," the special committee and the board of directors considered the proposed merger and decided to recommend the transaction because they believed that the opportunity to receive the $10.30 per share cash merger consideration was an attractive option to present to the stockholders of ISP, other than Mr. Heyman and his affiliates, in light of ISP's historical and current financial and trading performance and difficult general economic and stock market conditions. The special committee and the board of directors also considered the offer to be attractive for other reasons, including difficulties in remaining a publicly traded company with ISP's small public float and Mr. Heyman's unwillingness to cause ISP or his beneficial interest in ISP to be sold to a third party. EFFECTS OF THE MERGER; PLANS OR PROPOSALS AFTER THE MERGER After the effective time of the merger, holders of our common stock, other than Mr. Heyman and his affiliates, will cease to have ownership interests in ISP or rights as our stockholders, and instead will only be entitled to receive $10.30 in cash for each of their shares of our common stock. As a result of the merger, Mr. Heyman's interest in our net book value and net earnings will increase from approximately 81% to 100%, or by approximately $100.6 million in the case of book value. ISP reported a loss for the twelve months ending September 30, 2002, so Mr. Heyman is increasing his attributable share of ISP's recent net loss. As a result of the merger, Mr. Heyman will be the sole beneficiary of our future earnings and growth, if any. Similarly, Mr. Heyman will also bear the risk of any losses generated by our operations and any decrease in our value after the merger. As a result of the merger, ISPH will be merged with and into ISP and will cease to be a separate legal entity. None of Mr. Heyman, ISPH and ISP will recognize gain or loss for United States federal income tax purposes as a result of the merger. Following the merger, our common stock will no longer be traded on the New York Stock Exchange. In addition, the registration of our common stock under the Securities Exchange Act of 1934 will be terminated. Due to this termination, the periodic reporting requirements under that Act, certain provisions of Section 16(b) of that Act, and requirements that we furnish a proxy or information statement in connection with stockholders' meetings will no longer apply to us. After the effective time of the merger, there will be no publicly traded ISP common stock outstanding and we would no longer be required to file periodic reports with the Securities and Exchange Commission. Several of our subsidiaries, however, would continue to file periodic reports in respect of the outstanding debt securities of those entities. Specifically, our subsidiary International Specialty Holdings Inc. is currently required to file periodic reports pursuant to the Exchange Act and our primary operating subsidiary ISP Chemco Inc. and certain of its subsidiaries have agreed to file periodic reports with the Commission pursuant to an indenture for so long as ISP Chemco has indebtedness outstanding under that indenture. 31 From and after the effective time of the merger, our current directors (other than Mr. Sanford Kaplan and the members of the special committee) and officers will remain the directors and officers of ISP, until their successors are duly elected or appointed and qualified. Mr. Heyman expects that following completion of the merger, ISP's business operations will be conducted substantially as they are currently being conducted. Mr. Heyman has no other current plans or proposals or negotiations which relate to or would result in an extraordinary corporate transaction involving our corporate structure, business or management, such as a merger, reorganization, liquidation, relocation of any operations, or sale or transfer of a material amount of assets. Nevertheless, Mr. Heyman may initiate from time to time reviews of us and our assets, corporate structure, capitalization, operations, properties, management and personnel to determine what changes, if any, would be desirable following the merger in order best to organize ISP's activities. Mr. Heyman expressly reserves the right to make any changes that he deems necessary or appropriate in light of his review or in light of future developments. In addition, Mr. Heyman may also consider material changes in the present dividend rate and policy, indebtedness, capitalization and management and employee incentive plans and may consider pursuing acquisition opportunities through ISP. INTERESTS OF DIRECTORS AND EXECUTIVE OFFICERS IN THE MERGER ISP's board of directors and executive officers have various interests in the merger described in this section that are in addition to, or different from, the interests of ISP's stockholders generally. ISP stockholders should keep this in mind when considering the recommendation of ISP's board of directors that the stockholders vote to adopt the merger agreement. POSITIONS AFTER THE MERGER After the merger, Mr. Heyman and Mr. Kumar are expected to be the sole remaining directors of ISP. In addition, each current executive officer of ISP is expected to remain an executive officer of ISP after the merger. Mr. Heyman and ISP retain the right to name additional or different directors and executive officers after the merger, but currently have no intention to do so. There is no current plan or arrangement for materially increasing the compensation of any director or executive officer of ISP after the merger (although ISP expressly reserves the right to make any changes it deems necessary or appropriate in the future). For additional information regarding the compensation of our directors and executive officers, please see the annual report on Form 10-K that ISP and its subsidiaries have filed with the Securities and Exchange Commission. STOCK OPTIONS; RESTRICTED SHARES The merger agreement provides that as of the effective time, all outstanding and unexercised employee stock options on ISP common stock granted pursuant to the 1991 Incentive Plan for Key Employees and Directors and the 2000 Stock Option Plan for Non-Employee Directors will be canceled. The merger agreement provides that, in consideration for that cancellation, the holders of the options will have the right to receive a cash payment. The amount of this payment will equal the excess, if any, of the merger consideration of $10.30 in cash per share of ISP common stock over the per share exercise price of the options, multiplied by the number of shares of ISP common stock subject to those options, reduced by applicable withholding taxes. In addition, the merger agreement provides that each share of restricted ISP common stock will be canceled in consideration for the right to receive an amount in cash equal to $10.30, as reduced by applicable withholding taxes, subject to the vesting restrictions that were applicable to the underlying restricted shares. Our executive officers and directors currently hold a total of approximately 1,072,500 options. Approximately 496,000 of these options have an exercise price below the $10.30 merger consideration and all but 18,666 of those "in-the-money" options are vested. The aggregate payment that our executive officers and directors would be entitled to receive for all of their options as of the date of this proxy statement is approximately $1.58 million. In addition, our executive officers and directors hold approximately 500,000 restricted shares of ISP common stock. The table below sets forth the number of shares of ISPcommon stock subject to vested and unvested "in-the-money" stock options held, and shares of ISP common stock beneficially owned, by each of our executive officers and directors and the aggregate payment that each executive officer and director would be entitled to receive in connection with the merger as a result of such holdings. 32 "IN-THE-MONEY" OPTIONS: ------------------------------- NAME VESTED UNVESTED SHARES TOTAL PAYMENTS ---------- --------- --------- --------------- Samuel J.

The Annette Heyman Foundation, Inc., a charitable organization recognized as tax-exempt pursuant to Section 501(c)(3) of the Internal Revenue Code, holds 525,000 shares of ISP common stock. The Annette Heyman Foundation will be entitled to receive the merger consideration per share for each of these shares, or approximately $5,400,000. Mr. Heyman is deemed the beneficial owner of these shares because he is a director and the president of the foundation. These shares constitute less than 1% of the shares of ISPcommon stock beneficially owned by Mr. Heyman. Mr. Heyman expects to cause the sale of 114,336 shares of ISPcommon stock beneficially owned by him prior to the merger to non-affiliated persons in one or more sales pursuant to Rule 144 under the Securities Act of 1933. These shares were originally acquired in open market purchases from unaffiliated third parties for an average price per share of approximately $7.08 and represent less than 0.25% of the shares beneficially owned by Mr. Heyman. While the sale price for these shares cannot be determined at this time, it is likely that the sale price will be no more than $10.30 per share. Accordingly, Mr. Heyman anticipates that the sale proceeds will not exceed $1,177,661. The shares are being sold for personal tax and financial planning purposes. (2) Includes $2,575,000 to be paid, subject to vesting restrictions, in exchange for surrendering 250,000 restricted shares of ISP's common stock. (3) Includes $1,545,000 to be paid, subject to vesting restrictions, in exchange for surrendering 150,000 restricted shares of ISP's common stock. (4) Includes $1,030,000 to be paid, subject to vesting restrictions, in exchange for surrendering 100,000 restricted shares of ISP's common stock. INDEMNIFICATION AND INSURANCE Following the completion of the merger, ISP is required to indemnify, defend and hold harmless, to the full extent permitted by law, all current officers and directors of ISP against all losses, claims, damages, costs, expenses or liabilities or in connection with any claim, action, suit, proceeding or investigation arising out of the fact that the person is an officer or director of ISP (or out of any action taken by any such person on behalf of ISP), pertaining to any matter existing or occurring on or prior to the effective time of the merger (including the transactions contemplated by the merger agreement), whether asserted or claimed prior to, or on or after, the effective time of the merger. In addition, ISP is required to maintain its directors and officers' liability insurance policies in effect for six years after the effective time of the merger, except that ISP will not be required to pay annual insurance premiums in excess of 200% of the premiums it currently pays. On August 7, 2002, ISP entered into indemnity agreements with each member of the special committee. Pursuant to the indemnity agreements, ISP agreed to indemnify Messrs. Englander, Manning and Meckler for any expenses, liabilities and losses relating to their service as members of the special committee and/or the board of directors in connection with the transaction. These indemnity agreements are in addition to the indemnity available to the special committee members pursuant to ISP's amended and restated certificate of incorporation. MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER TO OUR STOCKHOLDERS The following is a summary of United States federal income tax consequences of the merger to stockholders whose shares of ISP common stock are converted into the right to receive cash pursuant to the merger. The discussion does not purport to consider all aspects of United States federal income taxation that might be relevant to our stockholders. The discussion is based 33 on current law which is subject to change possibly with retroactive effect. The discussion applies only to stockholders who hold shares of our common stock as capital assets, and may not apply to shares of our common stock received in connection with the exercise of employee stock options or otherwise as compensation, or to certain types of stockholders (such as insurance companies, tax-exempt organizations, financial institutions and broker-dealers) who may be subject to special rules. This discussion does not discuss the tax consequences to any of our stockholders who, for United States federal income tax purposes, is a non-resident alien individual, foreign corporation, foreign partnership or foreign estate or trust, and does not address any aspect of state, local or foreign tax laws. The receipt of cash for shares of our common stock pursuant to the merger will be a taxable transaction for United States federal income tax purposes. In general, a stockholder who surrenders shares of our common stock for cash pursuant to the merger will recognize capital gain or loss for United States federal income tax purposes equal to the difference, if any, between the amount of cash received and the stockholder's adjusted tax basis in the shares of ISP common stock surrendered. Gain or loss will be determined separately for each block of shares (i.e., shares acquired at the same cost in a single transaction) surrendered for cash pursuant to the merger. Such gain or loss will be long-term capital gain or loss provided that a stockholder's holding period for such shares is more than 12 months at the time of the consummation of the merger. Long-term capital gains of individuals are eligible for reduced rates of taxation. There are limitations on the deductibility of capital losses. In general, cash received by stockholders who exercise statutory appraisal rights under Section 262 of the DGCL in respect of such appraisal rights will result in the recognition of gain or loss to such stockholders. Any stockholder who is considering exercising statutory appraisal rights should consult with its own tax advisor for a full understanding of the tax consequences of the receipt of cash in respect of appraisal rights pursuant to the merger. Under the U.S. federal backup withholding tax rules, unless an exemption applies, the paying agent will be required to withhold, and will withhold, 30% of all cash payments to which a holder of shares is entitled pursuant to the merger agreement, unless the stockholder provides a tax identification number (social security number, in the case of an individual, or employer identification number, in the case of other stockholders), certifies that such number is correct, and otherwise complies with such backup withholding tax rules. Each of our stockholders should complete and sign the Substitute Form W-9 included as part of the letter of transmittal to be returned to the paying agent, in order to provide the information and certification necessary to avoid backup withholding tax, unless an exemption applies and is established in a manner satisfactory to the paying agent. THE U.S. FEDERAL INCOME TAX CONSEQUENCES SET FORTH ABOVE ARE NOT INTENDED TO CONSTITUTE A COMPLETE DESCRIPTION OF ALL TAX CONSEQUENCES RELATING TO THE MERGER. BECAUSE INDIVIDUAL CIRCUMSTANCES MAY DIFFER, EACH STOCKHOLDER SHOULD CONSULT THE STOCKHOLDER'S TAX ADVISOR REGARDING THE APPLICABILITY OF THE RULES DISCUSSED ABOVE TO THE STOCKHOLDER AND THE PARTICULAR TAX EFFECTS TO THE STOCKHOLDER OF THE MERGER, INCLUDING THE APPLICATION OF STATE, LOCAL AND FOREIGN TAX LAWS. LITIGATION In July of 2002, six purported class action suits were filed on behalf of ISP stockholders in the Court of Chancery of the State of Delaware against ISP and members of its board of directors. These six suits have been consolidated. On July 12, 2002, a seventh ISP stockholder filed a purported class action suit in the United States District Court, District of New Jersey, against ISP and members of its board of directors. The New Jersey claim was subsequently amended to assert derivative claims as well. The plaintiffs in the Delaware and New Jersey litigations seek to represent the same class of ISP stockholders. The Delaware and New Jersey complaints allege, among other things, that the defendants have breached fiduciary and other duties in connection with Mr. Heyman's proposal to acquire beneficial ownership of all shares of ISP common stock that he does not already beneficially own. These complaints variously seek a court order enjoining the proposed transaction, an award of unspecified damages and attorneys' fees, the unwinding of any transaction and other unspecified equitable relief. Following settlement discussions between counsel for Mr. Heyman and counsel for plaintiffs in the Delaware and New Jersey litigations, on November 19, 2002, the parties to the stockholder litigation pending in Delaware agreed on and executed a memorandum of understanding to reflect a proposed settlement of the Delaware litigation. The parties to the Delaware litigation also agreed, subject to the conditions described below, to enter into a settlement agreement, cooperate in public disclosures related to the settlement and use best efforts to gain approval of the settlement by the Delaware courts. Without any admission of fault by the defendants, the memorandum of understanding for the proposed settlement of the Delaware litigation contemplates a dismissal of all claims with prejudice and a release in favor of all defendants of any and all claims related to the proposed transaction (including the claims in the New Jersey litigation) that have been or could have been asserted by the plaintiffs and all members of a plaintiff class consisting of all record and beneficial holders of ISP common stock from July 7, 2002 through the completion of the merger. These dismissed claims are referred to in this proxy statement as the settled claims. 34 The proposed settlement of the Delaware litigation is subject to numerous conditions, including the completion of confirmatory discovery, execution of a settlement agreement containing a provision permitting defendants to terminate the settlement if, prior to final court approval, any action other than the New Jersey litigation is pending in any state or federal court which raises any settled claims, a determination by defendants prior to final court approval that the dismissal of the litigation in accordance with the settlement agreement will result in the release with prejudice of the settled claims, final approval of the settlement by the Delaware courts, and completion of the merger. Because the proposed settlement is subject to consummation of the merger and the other conditions described above, any settlement will not be final at the time you will be asked to vote on the merger. If the parties to the Delaware litigation do not proceed with the proposed settlement, or in the event the proposed settlement ultimately is not approved by the Delaware courts, the Delaware and New Jersey litigations could proceed and the plaintiffs could seek the relief sought in their complaints, including rescission of the merger or an award of damages in favor of the ISP stockholders in any plaintiff class that might be certified. If the proposed settlement of the Delaware litigation becomes final, the defendants believe that any and all settled claims against the defendants in the New Jersey litigation will be released and the defendants intend to move for a dismissal of the New Jersey litigation based on the final order in the Delaware litigation. 35 THE SPECIAL MEETING This proxy statement is furnished in connection with the solicitation of proxies by our board of directors in connection with a special meeting of our stockholders. DATE, TIME AND PLACE OF THE SPECIAL MEETING The special meeting is scheduled to be held as follows: DATE: February ___, 2003 TIME:_____________ PLACE: Offices of Simpson Thacher & Bartlett, 425 Lexington Avenue, New York, New York PROPOSAL TO BE CONSIDERED AT THE SPECIAL MEETING At the special meeting, you will be asked to consider and vote upon a proposal to adopt an agreement and plan of merger, dated as of November 8, 2002, between ISP and ISPH, a corporation 100% beneficially owned by Mr. Heyman and to consider such other business as may properly come before the meeting and all adjournments or postponements thereof. RECORD DATE The board of directors has fixed the close of business on January 10, 2003 as the record date for the special meeting and only holders of common stock on the record date are entitled to notice of and to vote at the special meeting. On that date, there were approximately 170 holders of record of ISP common stock, and 65,210,670 shares of common stock outstanding. On the record date, Mr. Heyman beneficially owned 52,567,240 outstanding shares of ISP common stock, representing approximately 80.6% of the total voting power of ISP. VOTING RIGHTS; VOTE REQUIRED FOR APPROVAL Each share of ISP common stock entitles its holder to one vote on all matters properly coming before the special meeting. A majority of the total number of all outstanding shares of common stock entitled to vote, represented in person or by proxy, will constitute a quorum at the special meeting. Mr. Heyman has agreed, pursuant to a voting agreement, to cause all of the shares beneficially owned by him at the time of the meeting (but excluding shares held by qualified charitable organizations) to be represented in person or by proxy at the meeting. Accordingly, a quorum at the meeting is assured. If you hold your shares in an account with a broker or bank, you must instruct the broker or bank on how to vote your shares. If an executed proxy card returned by a broker or bank holding shares indicates that the broker or bank does not have discretionary authority to vote on the adoption of the merger agreement, the shares will be considered present at the meeting for purposes of determining the presence of a quorum, but will not be voted on the proposal to adopt the merger agreement. This is called a broker non-vote. Your broker or bank will vote your shares only if you provide instructions on how to vote by following the instructions provided to you by your broker or bank. Under Delaware law, the merger agreement must be adopted by the affirmative vote of the holders of a majority of the shares of common stock outstanding and entitled to vote at the special meeting. Mr. Heyman has agreed in the voting agreement to cause all of the shares beneficially owned by him at the time of the meeting (but excluding shares held by qualified charitable organizations) to vote "FOR" the merger agreement, which will assure adoption of the merger agreement under Delaware law. In addition, although not required under the Delaware General Corporation Law or the amended and restated certificate of incorporation or by-laws of ISP, the merger agreement requires that the majority of the minority condition be satisfied. Abstentions, failures to vote and broker non-votes will have the same effect as a vote against the adoption of the merger agreement for purposes of obtaining a majority of all shares of ISP common stock. However, abstentions, failures to vote and broker non-votes will not affect satisfaction of the majority of the minority condition. Each of our directors and executive officers has indicated that he or she intends to vote his or her own shares in favor of adoption of the merger agreement. If Mr. Heyman and each of our directors and officers vote as we expect, 83% of the outstanding shares of ISP common stock will have voted for adoption of the merger agreement. 36 VOTING AND REVOCATION OF PROXIES Stockholders should mark, date, sign and return the proxy card and mail it in the enclosed envelope as soon as possible so that your shares are represented at the special meeting, even if you plan to attend the meeting in person. Proxies received at any time before the special meeting, and not revoked or superseded before being voted, will be voted at the special meeting. Where a specification is indicated by the proxy, it will be voted in accordance with the specification. Where no specification is indicated, the proxy will be voted "FOR" the proposal to adopt the merger agreement and in the discretion of the persons named in the proxy with respect to any other business which may properly come before the meeting or any adjournment of the meeting and which is not known a reasonable time before the meeting. However, the proxies do not grant authority to vote on any proposal to adjourn or postpone the special meeting for the purpose of soliciting further proxies in favor of adoption of the merger agreement. Our board of directors is not currently aware of any business to be brought before the special meeting other than that described in this proxy statement. Until your proxy is exercised at the special meeting, you can revoke your proxy and change your vote in any of the following ways: o by delivering written notification of revocation to our Secretary at our executive offices at 1361 Alps Road, Wayne, New Jersey 07470, o by delivering a proxy of a later date, o by attending the special meeting and voting in person. Your attendance at the special meeting will not, by itself, revoke any proxy previously delivered by you; you must vote in person at the meeting, or o if you have instructed a broker to vote your shares, by following the directions received from your broker to change those instructions. Votes will be tabulated by our transfer agent, The Bank of New York. SOLICITATION OF PROXIES We will bear the expenses in connection with the solicitation of proxies. Arrangements will also be made with brokerage houses and other custodians, nominees and fiduciaries for the forwarding of solicitation material to the beneficial owners of common stock held of record by such persons, and we may reimburse them for their reasonable transaction and clerical expenses. Solicitation of proxies will be made principally by mail. Proxies may also be solicited in person, or by telephone or facsimile by our officers and regular employees. These people will receive no additional compensation for these services, but will be reimbursed for any transaction expenses incurred by them in connection with these services. We have also retained Georgeson Shareholder Communications Inc., a proxy solicitation firm, for a fee of $7,500 plus transaction expenses, to assist in the solicitation of proxies from stockholders, including brokerage houses and other custodians, nominees and fiduciaries. THE MERGER This section of the proxy statement describes material aspects of the proposed merger, including the merger agreement, which is incorporated by reference to this proxy statement and is attached hereto as Annex A. While we believe that the description covers the material terms of the merger, this summary is qualified in its entirety by reference to the complete text of the merger agreement and may not contain all of the information that is important to you. You should carefully read this entire proxy statement, the merger agreement and the other documents we refer you to for a more complete understanding of the merger. In the merger, ISPH will merge into ISP with ISP as the surviving corporation in the merger. As a result of the merger, ISP will cease to be a publicly held company and will become a private corporation, all of the stock of which will be beneficially owned by Mr. Heyman. 37 EFFECTIVE TIME OF MERGER If the merger agreement is adopted by the requisite votes of stockholders and the other conditions to the merger are satisfied or waived to the extent permitted, the merger will be consummated and become effective at the time a certificate of merger is filed with the Secretary of State of the State of Delaware or any later time as ISP and ISPH agree upon and specify in the certificate of merger. The filing is expected to occur as soon as practicable after adoption of the merger agreement by ISP stockholders at the special meeting and satisfaction or waiver of the other conditions to the merger set forth in the merger agreement. Upon the completion of the merger, ISPH will cease to exist and ISP will continue as the surviving corporation. If our stockholders vote to adopt the merger agreement, we expect to complete the merger during the first quarter of 2003. PAYMENT OF MERGER CONSIDERATION AND SURRENDER OF STOCK CERTIFICATES If we complete the merger, our common stockholders (other than holders of common stock beneficially owned by Mr. Heyman and holders who perfected their appraisal rights under Delaware law) will be entitled to receive $10.30 in cash for each share of ISP common stock that they own. In addition, charitable organizations that own common stock will be entitled to receive $10.30 in cash for each share of ISP common stock that they own, even if the shares are beneficially owned by Mr. Heyman. A qualified charitable organization holds 525,000 shares of ISP common stock that are deemed to be beneficially owned by Mr. Heyman. The qualified charitable organization will receive $10.30 in cash for each of these shares, as described under "Special Factors--Interests of Directors and Executive Officers in the Merger." We will designate a paying agent to make the cash payments contemplated by the merger agreement. From time to time after the effective time of the merger, ISP will deposit in trust with the paying agent funds sufficient to pay the merger consideration to stockholders. The paying agent will deliver your merger consideration to you according to the procedure summarized below. After the effective time of the merger we will not transfer shares of common stock that were outstanding immediately prior to the effective time on our stock transfer books. If you present common stock certificates to us or our paying agent after the effective time of the merger, we will cancel them in exchange for cash as described in this section. As soon as practicable after the effective time of the merger, we will send you, or cause to be sent to you, a letter of transmittal and instructions advising you how to surrender your certificates in exchange for the merger consideration. The paying agent will pay your merger consideration, together with any dividends to which you are entitled, to you after you have surrendered your certificates to the paying agent. Interest will not be paid or accrue in respect of cash payments of merger consideration. We will reduce the amount of any merger consideration paid to you by any applicable withholding taxes. If the paying agent is to pay some or all of your merger consideration to a person other than you, you must have your certificates properly endorsed or otherwise in proper form for transfer, and you must pay any transfer or other taxes payable by reason of the transfer or establish to ISP's satisfaction that the taxes have been paid or are not required to be paid. YOU SHOULD NOT FORWARD YOUR STOCK CERTIFICATES TO THE PAYING AGENT WITHOUT A LETTER OF TRANSMITTAL, AND YOU SHOULD NOT RETURN YOUR STOCK CERTIFICATES WITH THE ENCLOSED PROXY. The transmittal instructions will tell you what to do if you have lost your certificate, or it has been stolen or destroyed. You will have to provide an affidavit to that fact and, if required by our paying agent or ISP, post a bond in an amount that the paying agent or ISP, as the case may be, reasonably directs as indemnity against any claim that may be made against those parties in respect of the certificate. At the effective time of and after the merger, subject to the exceptions in the next sentence, you will cease to have any rights as our stockholder. The exceptions include the right to receive dividends or other distributions with respect to your shares with a record date before the effective time and the right to surrender your certificates in exchange for payment of the merger consideration. ACCOUNTING TREATMENT For U.S. accounting and financial reporting purposes, the acquisition of shares in the merger will be accounted for under the purchase method of accounting. 38 FEES AND EXPENSES OF THE MERGER All fees and expenses in connection with the merger will be paid by the party incurring those fees and expenses, except that we will pay the expenses related to the preparation, printing and mailing of this proxy statement and all filing and other fees paid to the Securities and Exchange Commission in connection with the merger. The total fees and expenses in connection with the merger are estimated to be approximately $3.2 million. This amount consists of the following estimated fees: Legal and Other Professional Fees(1) $2,750,000 Printing, Proxy Solicitation and Mailing Costs 100,000 Special Committee Fees 60,000 Filing Fees (SEC) 26,873 Miscellaneous 250,000 ------------- ----------- Total $ 3,186,873 -------------- (1) Includes fees paid to Lehman Brothers Inc. FINANCING OF THE MERGER We and Mr. Heyman estimate that approximately $134.4 million will be required to complete the purchase of shares of our common stock, restricted stock and options pursuant to the merger (excluding the fees and expenses referred to above). Mr. Heyman and ISP expect this amount to be paid out of available funds of ISP at the effective time of the merger. We currently anticipate that ISP will obtain those funds by entering into an intercompany borrowing arrangement immediately prior to the closing of the merger with its indirect wholly owned subsidiary, ISP Investco LLC, pursuant to which ISP Investco LLC will lend ISP unrestricted funds sufficient to pay the costs and expenses of the merger, including the merger consideration. ISP Investco currently has sufficient capital to cover the cost of funding the merger consideration. The merger is not conditioned on any financing arrangements. APPRAISAL RIGHTS Under Section 262 of the DGCL, if you do not wish to accept $10.30 per share in cash for your shares of common stock, you may elect to have the fair value of your shares of common stock judicially determined and paid to you in cash, together with a fair rate of interest, if any. The valuation will exclude any element of value arising from the accomplishment or expectation of the merger. You may only exercise these rights if you comply with the provisions of Section 262. The following discussion is not a complete statement of the law pertaining to appraisal rights under the DGCL, and is qualified in its entirety by the full text of Section 262 set forth in Annex D. Under Section 262 of the DGCL, where a proposed merger is to be submitted for approval at a meeting of stockholders, as in the case of our special meeting, the corporation, not less than 20 days prior to the meeting, must notify each of its stockholders entitled to appraisal rights that these appraisal rights are available and include in that notice a copy of Section 262. This proxy statement will constitute this notice to the holders of common stock and the applicable statutory provisions of the DGCL are attached to this proxy statement as Annex D. Any stockholder who wishes to exercise those appraisal rights or who wishes to preserve the right to do so should review carefully the following discussion and Annex D to this proxy statement. FAILURE TO COMPLY WITH THE PROCEDURES SPECIFIED IN SECTION 262 OF THE DGCL TIMELY AND PROPERLY WILL RESULT IN THE LOSS OF APPRAISAL RIGHTS. Moreover, because of the complexity of the procedures for exercising the right to seek appraisal of the common stock, we believe that stockholders who consider exercising those rights should seek the advice of counsel. All references in Section 262 of the DGCL and in this summary to a "stockholder" are to the record holder of the shares of common stock as to which appraisal rights are asserted. A PERSON HAVING A BENEFICIAL INTEREST IN SHARES OF COMMON STOCK HELD OF RECORD IN THE NAME OF ANOTHER PERSON, SUCH AS A BROKER OR NOMINEE, MUST ACT PROMPTLY TO CAUSE THE RECORD HOLDER TO FOLLOW PROPERLY THE STEPS SUMMARIZED BELOW AND IN A TIMELY MANNER TO PERFECT APPRAISAL RIGHTS. 39 Any holder of common stock wishing to exercise the right to demand appraisal under Section 262 of the DGCL must satisfy each of the following conditions: o the holder must deliver to us a written demand for appraisal of its shares before the vote on the adoption of the merger agreement at the special meeting. This demand will be sufficient if it reasonably informs us of the identity of the stockholder and that the stockholder intends by that writing to demand the appraisal of its shares; o the holder must not vote its shares of common stock in favor of the adoption of the merger agreement. A proxy which does not contain voting instructions will, unless revoked, be voted in favor of the adoption of the merger agreement. Therefore, a stockholder who votes by proxy and who wishes to exercise appraisal rights must vote against the adoption of the merger agreement or abstain from voting on the merger agreement; and o the holder must continuously hold its shares from the date of making the demand through the effectiveness of the merger. A stockholder who is the record holder of shares of common stock on the date the written demand for appraisal is made but who thereafter transfers those shares prior to the effectiveness of the merger will lose any right to appraisal in respect of those shares. Voting against, abstaining from voting on or failing to vote on the proposal to adopt the merger agreement will not constitute a written demand for appraisal within the meaning of Section 262 of the DGCL. The written demand for appraisal must be in addition to, and separate from, any proxy you deliver or vote you cast in person. Only a holder of record of shares of common stock is entitled to assert appraisal rights for those shares registered in that holder's name. A demand for appraisal should: (1) be executed by or on behalf of the stockholder of record, fully and correctly, as its name appears on those stock certificates, and (2) specify the following: o the stockholder's name and mailing address, o the number of shares of common stock owned by the stockholder, and o that the stockholder intends thereby to demand appraisal of its common stock. If the shares are owned of record by a person in a fiduciary capacity, such as a trustee, guardian or custodian, the demand should be executed in that capacity. If the shares are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand should be executed by or on behalf of all owners. An authorized agent, including one or more joint owners, may execute a demand for appraisal on behalf of a stockholder; however, the agent must identify the record owner or owners and expressly disclose the fact that, in executing the demand, the agent is acting as agent for such owner or owners. A record holder such as a broker who holds shares as nominee for several beneficial owners may exercise appraisal rights with respect to the shares held for one or more beneficial owners while not exercising these rights with respect to the shares held for one or more other beneficial owners. In this case, the written demand should set forth the number of shares as to which appraisal is sought, and where no number of shares is expressly mentioned the demand will be presumed to cover all shares held in the name of the record owner. STOCKHOLDERS WHO HOLD THEIR SHARES IN BROKERAGE ACCOUNTS OR OTHER NOMINEE FORMS AND WHO WISH TO EXERCISE APPRAISAL RIGHTS ARE URGED TO CONSULT WITH THEIR BROKERS TO DETERMINE APPROPRIATE PROCEDURES FOR THE MAKING OF A DEMAND FOR APPRAISAL BY SUCH NOMINEE. A stockholder who elects to exercise appraisal rights pursuant to Section 262 of the DGCL should mail or deliver a written demand to: International Specialty Products Inc., 1361 Alps Road, Wayne, New Jersey 07470, Attention: Secretary. Within ten days after the effective time of the merger, ISP, as the surviving corporation, must notify each holder of our common stock who has complied with Section 262 of the DGCLand who has not voted in favor of the adoption of the merger agreement of the date that the merger became effective. Within 120 days after the effective time of the merger, but not after that date, either ISP or any stockholder who has complied with the requirements of Section 262 may file a petition in the Court of Chancery of the State of Delaware demanding a determination of the value of the shares of common stock held by all stockholders demanding appraisal of their shares. We are under no obligation to, and have no present intent to, file a petition for appraisal, and stockholders seeking to exercise appraisal rights should not assume that we will file a petition with respect to the fair value of the shares. Accordingly, stockholders who desire to have their shares appraised should initiate all necessary 40 action for the perfection of their appraisal rights within the time periods and in the manner prescribed in Section 262. Since we have no obligation to file a petition, your failure to do so within the period specified could nullify your previous written demand for appraisal. Under the merger agreement, we have agreed to give ISPH prompt notice of any demands for appraisal we receive prior to the effective time. Prior to the effective time, ISPH has the right to participate in and direct all negotiations and proceedings with respect to demands for appraisal under the DGCL. Prior to the effective time, we will not, except with the prior written consent of ISPH, make any payment with respect to any demands for appraisal, or offer to settle, or settle or otherwise negotiate, any demands. Within 120 days after the effectiveness of the merger, any stockholder that complies with the provisions of Section 262 of the DGCLto that point in time will be entitled to receive from us, upon written request, a statement setting forth the aggregate number of shares not voted in favor of the adoption of the merger agreement and with respect to which we have received demands for appraisal and the aggregate number of holders of those shares. We must mail this statement to the stockholder by the later of 10 days after receipt of a request or 10 days after expiration of the period for delivery of demands for appraisals under Section 262. A stockholder who timely files a petition for appraisal with the Court of Chancery of the State of Delaware must serve a copy upon ISP. ISP must then within 20 days file with the Register in Chancery of the State of Delaware a duly verified list containing the names and addresses of all stockholders who have demanded appraisal of their shares and who have not reached agreements with us as to the value of their shares. After notice to stockholders as may be ordered by the Court of Chancery of the State of Delaware, the Court of Chancery of the State of Delaware is empowered to conduct a hearing on the petition to determine which stockholders are entitled to appraisal rights. The Court of Chancery of the State of Delaware may require stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates to the Register in Chancery for notation on the certificates of the pendency of the appraisal proceedings, and if any stockholder fails to comply with the requirement, the Court of Chancery of the State of Delaware may dismiss the proceedings as to that stockholder. After determining which stockholders are entitled to an appraisal, the Court of Chancery of the State of Delaware will appraise the "fair value" of their shares. This value will exclude any element of value arising from the accomplishment or expectation of the merger, but will include a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. The costs of the action may be determined by the Court of Chancery of the State of Delaware and taxed upon the parties as the Court of Chancery of the State of Delaware deems equitable. Upon application of a stockholder, the Court of Chancery of the State of Delaware may also order that all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding be charged pro rata against the value of all of the shares entitled to appraisal. These expenses may include, without limitation, reasonable attorneys' fees and the fees and expenses of experts. STOCKHOLDERS CONSIDERING SEEKING APPRAISAL SHOULD BE AWARE THAT THE FAIR VALUE OF THEIR SHARES AS DETERMINED UNDER SECTION 262 OF THE DGCL COULD BE MORE THAN, THE SAME AS OR LESS THAN THE MERGER CONSIDERATION THEY WOULD BE ENTITLED TO RECEIVE PURSUANT TO THE MERGER AGREEMENT IF THEY DID NOT SEEK APPRAISAL OF THEIR SHARES. STOCKHOLDERS SHOULD ALSO BE AWARE THAT INVESTMENT BANKING OPINIONS AS TO FAIRNESS FROM A FINANCIAL POINT OF VIEW ARE NOT NECESSARILY OPINIONS AS TO FAIR VALUE UNDER SECTION 262. In determining fair value and, if applicable, a fair rate of interest, the Court of Chancery of the State of Delaware is to take into account all relevant factors. In WEINBERGER V. UOP, INC., the Supreme Court of the State of Delaware discussed the factors that could be considered in determining fair value in an appraisal proceeding, stating that "proof of value by any techniques or methods that are generally considered acceptable in the financial community and otherwise admissible in court" should be considered, and that "fair price obviously requires consideration of all relevant factors involving the value of a company." In WEINBERGER, the Supreme Court of the State of Delaware stated that "elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered." Section 262 of the DGCLprovides, however, that fair value is to be "exclusive of any element of value arising from the accomplishment or expectation of the merger." Any stockholder who has duly demanded an appraisal in compliance with Section 262 of the DGCLwill not, after the effectiveness of the merger, be entitled to vote the shares subject to that demand for any purpose or be entitled to the payment of dividends or other distributions on those shares. However, stockholders will be entitled to dividends or other distributions payable to holders of record of shares as of a record date prior to the effective time of the merger. 41 If any stockholder who demands appraisal of its shares of common stock under Section 262 of the DGCLfails to perfect, or effectively withdraws or loses, that holder's right to appraisal, the shares of common stock of that stockholder will be deemed to have been converted at the effective time into the right to receive the merger consideration. A stockholder will fail to perfect, or effectively lose or withdraw, its right to appraisal if no petition for appraisal is filed within 120 days after the effective time of the merger, or if the stockholder delivers to ISP, as the surviving corporation, a written withdrawal of its demand for appraisal and an acceptance of the merger, except that any attempt to withdraw made more than 60 days after the effective time of the merger will require the written approval of ISP, as the surviving corporation, and, once a petition for appraisal is filed, the appraisal proceeding may not be dismissed as to any holder absent court approval. If we do not approve a stockholder's request to withdraw a demand for appraisal when the approval is required or if the Court of Chancery of the State of Delaware does not approve the dismissal of an appraisal proceeding, the stockholder would be entitled to receive only the appraised value determined in any such appraisal proceeding. This value could be higher or lower than, or the same as, the value of the merger consideration. Failure to comply strictly with all of the procedures set forth in Section 262 of the DGCL will result in the loss of a stockholder's statutory appraisal rights. Consequently, any stockholder wishing to exercise appraisal rights is urged to consult legal counsel before attempting to exercise those rights. Mr. Heyman and his affiliates, as the holders of ISP common stock, may also elect to have the fair value of their common stock judicially determined by following the procedures described above. However, Mr. Heyman has agreed to vote, or cause to be voted, all of the shares of ISP common stock beneficially owned by him, at the time of the stockholder meeting, in favor of adoption of the merger agreement and has advised us that he has no intention of exercising appraisal rights with respect to any of its shares. REGULATORY APPROVALS AND OTHER CONSENTS We believe that there are no significant regulatory approvals or other consents required to complete the merger. THE MERGER AGREEMENT CERTIFICATE OF INCORPORATION, BY-LAWS AND DIRECTORS AND OFFICERS OF ISP AS THE SURVIVING CORPORATION When the merger is completed: o the amended and restated certificate of incorporation of ISP as in effect immediately prior to the effective time of the merger will be the amended and restated certificate of incorporation of ISP as the surviving corporation; o the by-laws of ISPH in effect immediately prior to the effective time will be the by-laws of ISP as the surviving corporation; o the directors of ISP immediately prior to the effective time (other than Sanford Kaplan and those directors on the special committee) will be the directors of ISP as the surviving corporation; and o the officers of ISP immediately prior to the effective time will be officers of ISP as the surviving corporation. CONVERSION OF COMMON STOCK At the effective time of the merger, each outstanding share of ISP common stock will automatically be converted into the right to receive $10.30 in cash, without interest, except for: o shares of ISP common stock beneficially owned by Mr. Heyman, which will be canceled without any payment, except shares held by charitable organizations, which will be converted into the right to receive $10.30 in cash, without interest; o shares of ISP common stock that are held in the treasury of ISP or by any subsidiary of ISP, which will be canceled without any payment; and o shares held by stockholders validly perfecting appraisal rights in accordance with the DGCL. At the effective time, each outstanding share of ISPH stock issued and outstanding prior to the effective time will be converted into one share of common stock of ISP as the surviving corporation. 42 TREATMENT OF STOCK OPTIONS AND RESTRICTED SHARES Each outstanding option granted under ISP's stock option plans will be canceled at the effective time of the merger, and in consideration for such cancellation, ISP as the surviving corporation shall pay in cash after the effective time to each option holder the excess, if any, of the merger consideration over the option's exercise price multiplied by the number of shares of ISP common stock subject to the option immediately prior to the effective time of the merger. ISP will cause each holder of a share of restricted ISP common stock to surrender, immediately prior to the effective time of the merger, the restricted shares in exchange for a cash payment in an amount equal to the merger consideration, provided that the cash payment will only be payable at the time when the vesting restrictions on the restricted stock would have lapsed if the merger had not occurred. Cash payments made in exchange for stock options or restricted stock will be made without interest and will be reduced by any applicable withholding taxes. REPRESENTATIONS AND WARRANTIES The merger agreement contains various representations and warranties made by ISP to ISPH, subject to various qualifications and limitations, including representations and warranties relating to: o ISP's due organization, valid existence, good standing and necessary corporate power and authority of ISP and its subsidiaries to carry on its business; o the capitalization of ISP; o the accuracy of information concerning ISP's subsidiaries in ISP's Securities and Exchange Commission filings and the capitalization of these subsidiaries; o the authorization, execution, delivery and enforceability of the merger agreement; o the absence of any required governmental consents, approvals, authorization, or permits, except those specified in the merger agreement; o the absence of any conflicts between the merger agreement and ISP's amended and restated certificate of incorporation or by-laws, or a material conflict with any applicable laws and any other material contracts or documents; o the accuracy and adequacy of information concerning ISP in this proxy statement, any other document to be filed with the Securities and Exchange Commission in connection with the merger and all other filings made by ISP with the Securities and Exchange Commission; o the compliance of ISP with applicable laws; o the absence of any litigation or claims against ISP or any of its subsidiaries; o the qualification of each of ISP's employee benefit plans and other agreements with its employees under Section 401 of the Internal Revenue Code, and the absence of any payments that would be required as a result of the merger; o the absence of any fees owed to brokers or investment bankers (other than Lehman Brothers) in connection with the merger; o the absence of any material changes to ISP's business, earnings, assets, liabilities, financial or other condition or results of operations from December 31, 2001 until the effective time of the merger, except for changes disclosed in ISP's filings with the Securities and Exchange Commission; o the absence of material liabilities or obligations, except as disclosed in ISP's filings with the Securities and Exchange Commission; o the accuracy of information in ISP's financial reports concerning the real property owned or leased by ISP; o good and marketable title to all the properties and assets reflected on ISP's balance sheet as being owned by ISP or one of our subsidiaries or acquired after the date of the merger agreement and which are material to our business; and o the receipt by the special committee of an opinion from the special committee's financial advisors that the merger consideration is fair, from a financial point of view, to ISP's stockholders (other than Mr. Heyman). 43 The merger agreement contains various representations and warranties made by ISPH to ISP, subject to various qualifications and limitations, including representations and warranties relating to: o the due organization, valid existence, good standing and necessary corporate power and authority of ISPH to carry on its business; o the capitalization of ISPH; o the authorization, execution, delivery and enforceability of the merger agreement; o the absence of any required governmental consents, approvals, authorization or permits, except those specified in the merger agreement; o the absence of any conflicts between the merger agreement and ISPH's certificate of incorporation or by-laws, any applicable laws and any other material contracts or documents; o the accuracy and adequacy of information provided by ISPH in connection with this proxy statement and the related filings with the Securities and Exchange Commission; o the absence of any knowledge of any current intention of Mr. Heyman to sell ISP as of the date of the merger agreement; and o the absence of any knowledge of any breaches or inaccuracies of ISP's representations and warranties contained in the merger agreement. CONDUCT OF BUSINESS PENDING THE MERGER ISP has agreed that, prior to the effective time of the merger, except as consented to by ISPH, neither our board of directors nor any board committee will approve any action that would cause ISP or any of its subsidiaries to: o split, combine or reclassify any capital stock; o make, declare or pay dividends; o repurchase, redeem or otherwise acquire any shares of ISP's capital stock; o grant any additional options, warrants or restricted shares, or any capital stock or other equity interests; o enter into any voting agreement or arrangement regarding its capital stock; o incur any indebtedness for borrowed money or assume or guarantee indebtedness of any other person, other than in the ordinary course of business, consistent with past practice, or incur other capital expenditures, obligations or liabilities, other than those budgeted as of the date of the merger agreement or in the ordinary course of business, consistent with past practice; o dispose of any material properties or assets or cancel or release any material indebtedness; o make any material investment in any entity, other than in ISP's wholly owned subsidiaries or in the ordinary course of business, consistent with past practice; o enter into, terminate or make any material change to any material lease, contract or agreement, other than renewals in the ordinary course of business, consistent with past practice; o increase compensation or benefits of current or former employees, consultants or directors, other than in the ordinary course of business, consistent with past practice, or as required by law or contracts in effect as of the date of the merger agreement; o settle any material claim, action or proceeding; o change accounting methods or methods of reporting for tax purposes, except as required by changes in GAAP or changes in applicable law; o amend any certificate of incorporation, by-laws or plan of consolidation, merger or reorganization; o take any intentional actions that would result, or might reasonably be expected to result, in any of the representations or warranties of ISP not being true, or in any conditions to the merger not being satisfied; or 44 o agree to, commit to, or take any action described above. PROXY STATEMENT ISP and ISPH agreed to cooperate in preparing and ISP agreed to file as soon as practicable, this proxy statement and a transaction statement on Schedule 13E-3 along with any other filing required by the Securities and Exchange Commission or other regulatory authority in connection with the merger. ISP agreed to use its reasonable best efforts to reply to any Securities and Exchange Commission comments and promptly mail copies of this proxy statement and transaction statement on Schedule 13E-3 to its shareholders after responding to such comments. ISP and ISPH agreed to promptly notify one another of receipt of any Securities and Exchange Commission comments or requests for amendments or information and supply one another with copies of all correspondence between its representatives and the Securities and Exchange Commission regarding such filings. If an event occurs prior to the special meeting of stockholders that would require an amendment to this proxy statement or the transaction statement on Schedule 13E-3, we agreed to prepare and mail such an amendment to our stockholders, provided that no such amendment will be made without providing ISPH an opportunity to comment on the amendment. SPECIAL MEETING; ISP'S BOARD OF DIRECTORS' COVENANT TO RECOMMEND ISP agreed to, consistent with applicable law, call and hold a meeting of our stockholders as soon as practicable following the date of the merger agreement for the purpose of voting on the adoption of the merger agreement. ISP also agreed to include in this proxy statement and in the transaction statement on Schedule 13E-3 the recommendation of our board of directors (acting upon the recommendation of the special committee) that our stockholders (other than Mr. Heyman) vote to adopt the merger agreement. Neither the board of directors of ISP nor any of its committees (including the special committee) may withdraw, qualify or modify, or propose publicly to withdraw, qualify or modify its approval or recommendation of the approval of the merger agreement and the transactions it contemplates, or take any other action or make any other statement in connection with the special meeting inconsistent with its recommendation. However, in the event that prior to the receipt of the necessary approvals by ISP's stockholders, the special committee determines in good faith, after receipt of advice from outside counsel, that the failure to do so would more likely than not constitute a breach of its fiduciary duties to the stockholders of ISP (other than Mr. Heyman) under applicable law, then the board of directors (acting upon the recommendation of the special committee) or the special committee may withdraw, qualify or modify, or propose publicly to withdraw, qualify or modify its approval or recommendation of the approval of the merger agreement and the transactions it contemplates. Nonetheless, the merger agreement shall still be submitted to the stockholders of ISP for adoption at the special meeting. REASONABLE EFFORTS Subject to the terms and conditions provided in the merger agreement, both ISP and ISPH agreed to use reasonable efforts to make, or cause to be made, all filings necessary, proper or advisable under applicable laws and regulations to consummate and make effective the transactions contemplated by the merger agreement. Both ISP and ISPH agreed to use their reasonable best efforts to furnish each other with all information required for any filings in connection with the merger agreement. If, at any time after the effective time of the merger, any further action is necessary or desirable to carry out the purposes of the merger agreement, including the execution of additional instruments, the proper officers and directors of each party to the merger agreement agreed to take all such necessary action. ACCESS TO INFORMATION ISP has agreed that from the date of the merger agreement until the effective time of the merger, we will (i) provide to the officers, stockholders, attorneys, financial advisors, accountants, and other representatives of ISPH, reasonable access at all reasonable times to the offices, records and files, correspondence, audits and properties, as well as to all information relating to commitments, contracts, titles and financial position, or otherwise pertaining to the business and affairs, of ISP and our subsidiaries, (ii) furnish to ISPH and its stockholders, counsel, financial advisors, auditors and other authorized representatives such financial and operating data and other information as such persons may reasonably request and 45 (iii) instruct the employees, counsel and financial advisors of ISP and our subsidiaries to cooperate with ISPH in its investigation of the business of ISP and our subsidiaries. CONDITIONS TO THE MERGER CONDITIONS TO EACH PARTY'S OBLIGATION. The obligations of ISP and ISPH to complete the merger are subject to the satisfaction or waiver on or prior to the effective time of the merger of the following conditions: o the merger and the merger agreement shall have been adopted by the affirmative vote of (i) the holders of a majority of the outstanding shares of ISP common stock, and (ii) the holders of a majority of the shares of ISP common stock cast either for or against the adoption of the merger agreement (excluding shares that are owned beneficially or of record by any officer or director of ISP or ISPH); and o the absence of any injunction or order or any statute, rule or regulation that would prevent the completion of the merger and the absence of any action brought by any governmental authority seeking to obtain an injunction to prevent, materially delay, restructure or otherwise question the transactions contemplated by the merger agreement; CONDITIONS TO ISPH'S OBLIGATION. The obligations of ISPH to complete the merger are subject to the satisfaction or waiver, on or prior to the effective time of the merger, of the following conditions: o the representations and warranties made by ISP in the merger agreement must be true and correct as of the date of the merger agreement and as of the effective time, except such failures at the effective time that, in the aggregate, would not reasonably be expected to have a material adverse effect on ISP or consummation of the merger; and o ISP must have performed in all material respects all obligations under the merger agreement required to be performed at or prior to the effective time. CONDITIONS TO ISP'S OBLIGATION. The obligations of ISP to complete the merger are subject to the satisfaction or waiver, on or prior to the effective time of the merger, of the following conditions: o the representations and warranties made by ISPH in the merger agreement must be true and correct as of the date of the merger agreement and as of the effective time (except with respect to representations and warranties that speak as of another date), except such failures at the effective time that, in the aggregate, would not reasonably be expected to have a material adverse effect on the consummation of the merger; and o ISPH must have performed in all material respects all obligations under the merger agreement required to be performed at or prior to the effective time. TERMINATION OF THE MERGER AGREEMENT The merger agreement may be terminated and the merger may be abandoned at any time prior to the effective time of the merger: o by mutual written consent of ISP (provided that such termination has been approved by the special committee) and ISPH; o by either ISP (provided that such termination has been approved by the special committee) or ISPH if a governmental entity of competent jurisdiction issues a final nonappealable injunction or other ruling permanently enjoining or otherwise prohibiting the merger; o by either ISP (provided that such termination has been approved by the special committee) or ISPH if the merger is not completed on or before May 31, 2003, unless the failure to complete the merger is due to the failure of the party seeking to terminate the merger agreement to fulfill its obligations under the merger agreement; o by either ISP (provided that such termination has been approved by the special committee) or ISPH if there is a breach of the representations, warranties or covenants as set forth in the merger agreement on the part of ISP (in the case of termination by ISPH) or ISPH (in the case of termination by ISP), and that breach is not cured in the 30-day period following written notice to the party committing such a breach or cannot be cured prior to May 31, 2003, provided that such breach would constitute, individually or in the aggregate with other breaches, the failure of the conditions to the obligations set forth above; 46 o by either ISP (provided that such termination has been approved by the special committee) or ISPH if the special meeting is held and the stockholders fail to adopt the merger agreement by the requisite votes described above, provided that ISPH shall not have the right to terminate under this section if Mr. Heyman has failed to cause the shares beneficially owned by him at the time of the meeting to be voted in favor of the merger; or o by ISPH if the ISP board of directors or the special committee withdraws, qualifies or modifies its recommendation to ISP's stockholders to adopt the merger agreement, or publicly proposes to do so, or takes any other action or makes any other statement inconsistent with that recommendation. EFFECT OF TERMINATION If the merger agreement is terminated by either ISP or ISPH, as provided above, there will be no liability on the part of ISP, ISPH or any of their affiliates, directors, officers, employers or stockholders. However, no party will be relieved from liability for willful breaches of the merger agreement. AMENDMENTS The merger agreement may be amended by ISP (acting upon approval of the special committee) and ISPH at any time before or after any required approval of matters presented in connection with the merger by the stockholders; provided, however, that after any such approval, no amendment may be made that by law requires further approval by such stockholders without such approval (including the majority of the minority condition). OTHER MATTERS SECURITY OWNERSHIP OF SPECIFIED BENEFICIAL OWNERS AND MANAGEMENT The following table sets forth certain information regarding the beneficial ownership of ISP as of January 30, 2003 by (1) all those known to ISP to be beneficial owners of more than 5% of our common stock, (2) each executive officer and director of ISP and ISPH and (3) all executive officers and directors of ISP and ISPH as a group. ISPH currently does not beneficially own any ISP common stock.

Mr. Heyman disclaims any pecuniary interest in these shares in excess of his interests in such entities. Mr. Heyman also may be deemed to beneficially own 525,000 of these shares in his capacity as director and the president of The Annette Heyman Foundation, Inc., a charitable organization recognized as tax-exempt pursuant to Section 501(c)(3) of the Internal Revenue Code. Mr. Heyman disclaims any pecuniary interest in these shares. 47 (2) Includes with respect to Mr. Heyman, 239,200 shares, Mr. Kumar, 100,000 shares, Mr. Weinberg, 431,350 shares, Ms. Yoss, 69,350 shares, Mr. Cope, 77,335 shares, Mr. Englander, 1,667 shares, Mr. Grenner, 11,000 shares, Mr. Kaplan, 21,500 shares, Mr. Manning, 21,500 shares and Mr. Meckler, 1,667 shares and all executive officers and directors, 974,569 shares subject to options granted under the 1991 Incentive Plan for Key Employees and Directors, as amended, of ISP and the 2000 Stock Option Plan for Non-Employee Directors of ISP that are currently exercisable or will become exercisable within the next 60 days.

(6) Includes, with respect to Mr. Olsen, grants of 100,000 shares in the aggregate of restricted common stock of ISP. TRANSACTIONS IN CAPITAL STOCK BY CERTAIN PERSONS PURCHASES BY ISP The table below sets forth information, by fiscal quarters, regarding purchases by ISP of its common stock for the past two years, including the number of shares purchased on a quarterly basis, and the high, low and average price paid. PRICE PER SHARE NUMBER OF --------------------------------------------------- SHARES LOW HIGH AVERAGE ----------- ----------- ----------- ----------- 2003 First Quarter (through January 30, 2003) ................ 0 -- -- -- 2002 Fourth Quarter ................... 0 -- -- -- Third Quarter .................... 0 -- -- -- Second Quarter ................... 0 -- -- -- First Quarter .................... 177,600 $7.84 $9.00 $8.42 2001 Fourth Quarter ................... 640,900 7.99 8.35 8.29 Third Quarter .................... 822,500 8.07 10.75 9.83 Second Quarter ................... 312,900 8.00 10.32 9.23 First Quarter .................... 161,500 6.75 8.25 7.50 2000 Fourth Quarter ................... 1,273,000 5.13 6.38 5.32 PURCHASES BY MR. HEYMAN AND HIS AFFILIATES AND ISPH AND ITS DIRECTORS AND EXECUTIVE OFFICERS Except for the purchases referred to above, none of Mr. Heyman and his affiliates and ISPH and its directors and executive officers has purchased any shares of ISP common stock during the past two years. RECENT TRANSACTIONS There have been no transactions in shares of ISP common stock during the past 60 days by ISP, any of its directors or executive officers, ISPH, any of its directors or executive officers, or Mr. Heyman, except the following: o In accordance with the merger agreement, each of Mr. Kumar, Mr. Olsen and Ms. Yoss have entered into an agreement with ISP providing that immediately prior to the effective time of the merger, their shares of restricted stock will be surrendered in exchange for the right to receive the cash merger consideration per share, subject to the vesting restrictions currently applicable to their restricted shares. o Mr. Cope (1) exercised stock options to acquire 1,219 shares of our common stock on September 29, 2002, (2) exercised stock options to acquire 3,375 shares of our common stock on November 20, 2002, and (3) sold 3,375 shares of our common stock at an average price of $9.998 per share on November 20, 2002. 48 o On December 5, 2002, 525,000 shares beneficially owned by Mr. Heyman were donated to The Annette Heyman Foundation, Inc., a charitable organization recognized as tax-exempt pursuant to Section 501(c)(3) of the Internal Revenue Code. Mr. Heyman is a director and the president of the foundation and, therefore, continues to be deemed a beneficial owner of these shares. These shares constitute less than 1% of the shares of ISP common stock beneficially owned by Mr. Heyman. PLANNED TRANSACTIONS Mr. Heyman expects to cause 114,336 shares of ISP common stock beneficially owned by him to be sold prior to the special meeting to non-affiliated persons in one or more sales pursuant to Rule 144 under the Securities Act of 1933. These shares were originally acquired in open market purchases from unaffiliated third parties for an average price per share of approximately $7.08 and represent less than 0.25% of the shares beneficially owned by Mr. Heyman. While the sale price for these shares cannot be determined at this time, it is likely that the sale price will be no more than $10.30 per share. Accordingly, Mr. Heyman anticipates that the sale proceeds will not exceed $1,177,660.80. Mr. Heyman reserves the right not to sell these shares. The shares are being sold for personal tax and financial planning purposes. If the merger is approved by the required votes at the special meeting, then Mr. Heyman expects to cause legal ownership of all of the shares of ISP common stock beneficially owned by him at that time to be transferred to ISPH. The transfer will take place shortly before the merger and will have no economic or other effect on the holders of shares not beneficially owned by Mr. Heyman. Mr. Heyman reserves the right not to transfer these shares. CERTAIN TRANSACTIONS STOCKHOLDER VOTING AGREEMENT On November 8, 2002, Mr. Heyman and ISP entered into a stockholder voting agreement, a copy of which is included as Annex C to this proxy statement. Pursuant to the stockholder voting agreement, Mr. Heyman agreed, subject to the terms, conditions and exceptions in that agreement, to cause the shares of common stock of ISP then beneficially owned by him at the time of the special meeting (but excluding shares owned by charitable organizations) to be voted in favor of adoption of the merger agreement and to refrain from transferring shares of ISP common stock pending the merger, except with regard to the disposition of up to 114,336 shares of ISP common stock owned by Heyman Joint Venture II LLC. INVESTMENT MANAGEMENT ACTIVITIES We conduct our investments business through ISP Investco and its subsidiaries. We invest primarily in international and domestic arbitrage and securities of companies involved in acquisition or reorganization transactions. Those investments include common stock short positions which are offset against long positions in securities which are expected, under specific circumstances, to be exchanged or converted into the short positions. We generally make these investments at the same time and price that certain investment partnerships controlled by Mr. Heyman and his family are making similar investments. Management of this investment activity is provided by personnel of investment partnerships controlled by Mr. Heyman and his family, assisted by certain of our personnel, at no cost or charge to either party. MANAGEMENT AGREEMENT Pursuant to a management agreement, ISP, through a subsidiary, provides certain general management, administrative, legal, telecommunications, information and facilities services to Building Materials Corporation of America, or BMCA, an affiliate of ISP. The management agreement charges consist of management fees and other reimbursable expenses attributable to, or incurred by ISP for the benefit of BMCA and are based on an estimate of the costs ISP incurs to provide those services. ISP and BMCA also allocate a portion of the management fees payable by BMCA under the management agreement to separate lease payments for the use of BMCA's headquarters. Based on the services provided by ISP in 2002 under the management agreement, the aggregate amount payable to ISP under the management agreement for 2003, net of the lease payments to a subsidiary of G-I Holdings, is expected to be approximately $6.0 million. 49 Some of the executive officers of ISP perform services for affiliates of ISP pursuant to the management agreement, and ISP is indirectly reimbursed for those services by virtue of the management fees and other reimbursable expenses payable under the management agreement. In this regard, Mr. Weinberg and Ms. Yoss received $500,000 and $300,000, respectively, of additional compensation in connection with services performed by them for BMCA in 2001. BMCA reimbursed ISP for these payments pursuant to the management agreement. Although, due to the unique nature of the services provided under the management agreement, comparisons with third party arrangements are difficult, ISP believes that the terms of the management agreement, taken as a whole, are no less favorable to ISP than could be obtained from an unaffiliated third party. CERTAIN OTHER TRANSACTIONS In connection with becoming President and Chief Executive Officer of ISP in June 1999, Mr. Kumar was granted the right to purchase, and did purchase, 318,599 shares of ISP common stock for an aggregate purchase price of $3,046,762. Under the purchase agreement, ISP extended a loan to Mr. Kumar the funds to purchase the shares, which was evidenced by a recourse promissory note in the principal amount of $3,046,762. The loan was converted to a demand note and bears interest at the lowest applicable federal rate for short-term instruments. The principal amount of the loan is payable, unless ISP has previously declared the loan to be due and payable, in four installments on each June 11 of the years 2001, 2002 and 2003 and on January 11, 2004, the first three of which are in the amount of $761,691 each and the last of which is for the balance of the then outstanding principal amount. If, however, Mr. Kumar remains continuously employed by ISP or any of its subsidiaries through each installment payment date, the principal amount due on such installment payment date will be forgiven. In addition, upon the occurrence of certain events, including a change of control of ISP, the principal amount of the loan then outstanding shall be immediately forgiven. If Mr. Kumar's employment with ISP is otherwise terminated for any reason whatsoever, the entire principal balance outstanding, together with all interest accrued, will be immediately due and payable at ISP's election. In January 2001, July 2001, January 2002 and July 2002, we made loans to Ms. Yoss in the principal amounts of $44,282, $78,855, $71,349 and $57,461, respectively, to enable her to satisfy certain withholding tax obligations in connection with her award of 150,000 shares of restricted common stock of ISP, 18,750 shares of which vested on each of January 1, 2001, July 1, 2001, January 1, 2002 and July 1, 2002. The remainder of those shares vest in 12.5% increments every six months thereafter until full vesting on January 1, 2004, subject to specified terms and conditions. Each loan bears interest at the lowest applicable federal rate, as it may be adjusted from time to time. Each loan is due and payable in full, together with accrued interest, on demand and, in any event, not later than April 15, 2003. FUTURE STOCKHOLDER PROPOSALS Due to the contemplated consummation of the merger, ISP does not currently expect to hold a public 2003 annual meeting of stockholders because, following the merger, ISP will not be a publicly held company. If the merger is not consummated for any reason, proposals of stockholders intended to be considered for inclusion in the proxy statement for presentation at the 2003 Annual Meeting of Stockholders must have been received by ISP in writing at its principal executive offices on or before December 13, 2002 (or, if the date of the annual meeting is changed by more than 30 days from May 16, 2003, a reasonable time before ISP begins to print and mail its proxy materials). All proposals received will be subject to the applicable rules of the Securities and Exchange Commission. With regard to stockholders who intend to present a proposal at the 2003 Annual Meeting of Stockholders without including the proposal in ISP's proxy statement and fail to submit the proposal on or before February 26, 2003 (or, if the date of the annual meeting is changed by more than 30 days from May 16, 2003, a reasonable time before ISP mails its proxy materials), then the persons named as proxies in ISP's proxy card accompanying the proxy statement for the 2003 Annual Meeting of Stockholders will be allowed to use their discretionary voting authority when the proposal is raised at the meeting, without any discussion of the matter in ISP's proxy statement for the 2003 Annual Meeting of Stockholders. INDEPENDENT AUDITORS The consolidated financial statements of ISP incorporated in this proxy statement by reference to ISP's Annual Report on Form 10-K for the year ended December 31, 2001, have been incorporated in reliance on the report of Arthur Andersen LLP, independent accountants. On June 20, 2002, the Board of Directors of ISP, upon the recommendation of its audit committee, decided not to renew the engagement of its independent auditors, Arthur Andersen, and selected KPMG LLP as its independent auditors for the fiscal year ending December 31, 2002. The change in auditors became effective June 21, 2002. It is not anticipated that a representative of KPMG will attend the special meeting. 50 WHERE YOU CAN FIND MORE INFORMATION ISP files annual, quarterly and current reports, proxy statements and other information with the Securities and Exchange Commission.

RECITALS WHEREAS, the Company has authority to issue (i) 300,000,000 shares of Common Stock, par value $0.01 per share (the "COMPANY COMMON STOCK"), 65,105,602 of which were outstanding as of November 6, 2002, and (ii) 20,000,000 shares of Preferred Stock (the "COMPANY PREFERRED STOCK"), none of which are outstanding; WHEREAS, Samuel J. Heyman, an individual (the "MAJORITY STOCKHOLDER"), is the "beneficial owner" (as defined in Section 10.04) of 52,328,040 shares of Company Common Stock, representing approximately 80.4% of the Company Common Stock (the "MAJORITY STOCKHOLDER SHARES"), and all of the 3,000 outstanding shares of common stock, par value $0.001 per share (the "ISPH STOCK"), of ISPH; WHEREAS, ISPH is a Delaware corporation formed for the purpose of entering into this Agreement and consummating the transactions contemplated hereby; WHEREAS, the Majority Stockholder has proposed to the Board of Directors of the Company that ISPH be merged into the Company in a transaction in which shares of the Company beneficially owned by persons other than the Majority Stockholder at the time of the merger will be converted into the right to receive $10.30 per share in cash; WHEREAS, a special committee (the "SPECIAL COMMITTEE") of the Board of Directors of the Company and the Board of Directors of the Company (with the Majority Stockholder and Sunil Kumar abstaining) each has determined that it is fair to, and in the best interests of, the Company and the holders of Company Common Stock to consummate the merger (the "MERGER") of ISPH with and into the Company upon the terms and subject to the conditions set forth in this Agreement and in accordance with the Delaware General Corporation Law (the "DGCL"); WHEREAS, the Board of Directors of ISPH has approved and declared advisable this Agreement and the Merger and the other transactions contemplated hereby upon the terms and subject to the conditions set forth in this Agreement and in accordance with the DGCL; WHEREAS, the Majority Stockholder has agreed, pursuant to a Voting Agreement (the "VOTING AGREEMENT") dated as of the date hereof, to vote or cause to be voted all shares of Company Common Stock then beneficially owned by the Majority Stockholder in favor of the adoption of the Agreement at any meeting of stockholders of the Company at which the Agreement shall be submitted for adoption and at all adjournments or postponements thereof; NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained and intending to be legally bound hereby, the parties agree as follows: ARTICLE I THE MERGER SECTION 1.01 THE MERGER. Upon the terms and subject to the conditions set forth in Articles VI, VII and VIII, and in accordance with the provisions of the DGCL, at the Effective Time (as defined in Section 1.02), ISPH shall be merged with and into the Company. As a result of the Merger, the separate existence of ISPH shall cease, and the Company shall continue as the surviving corporation (the "Surviving Corporation"). SECTION 1.02 EFFECTIVE TIME; CLOSING. The closing of the Merger (the "Closing") shall take place (i) at the offices of Simpson Thacher & Bartlett, 425 Lexington Avenue, New York, New York at 9:00 a.m. New York City time on the next business day after all of the conditions set forth in Articles VI, VII and VIII have been satisfied or, subject to applicable law, waived (other than those conditions that by their nature are to be satisfied at the Closing, but subject to the satisfaction or waiver of those conditions) in accordance with this Agreement or (ii) at such other place and time and/or on such other date as ISPH and the Company may agree in writing (the "Closing Date"). Subject to the provisions of this Agreement, as soon as practicable on the Closing Date, the parties hereto shall file a certificate of merger (the "Certificate of Merger") with the Secretary of State of the State of Delaware, in such form as is required by, and executed in accordance with, the DGCL. The term "Effective A-1 Time" means the date and time that the Merger shall become effective, which shall be the date and time of the filing of the Certificate of Merger with the Secretary of State of the State of Delaware (or such later time as may be agreed by the parties hereto and specified in the Certificate of Merger). SECTION 1.03 EFFECT OF THE MERGER. At the Effective Time, the effect of the Merger shall be as provided in the applicable provisions of the DGCL. Without limiting the generality of the foregoing, and subject thereto, at the Effective Time, without further act or deed, all the property, rights, privileges, powers and franchises of the Company and ISPH shall vest in the Surviving Corporation and all debts, liabilities and duties of each of the Company and ISPH shall become the debts, liabilities and duties of the Surviving Corporation. SECTION 1.04 CERTIFICATE OF INCORPORATION; BYLAWS. (a) CERTIFICATE OF INCORPORATION.

(b) BYLAWS. At the Effective Time, the Bylaws of ISPH as in effect immediately prior to the Effective Time shall be the Bylaws of the Surviving Corporation until thereafter amended in accordance with their terms and as provided by the DGCL and the Certificate of Incorporation of the Surviving Corporation. SECTION 1.05 DIRECTORS AND OFFICERS. (a) DIRECTORS. From and after the Effective Time, the directors of the Company immediately prior to the Effective Time (other than Sanford Kaplan and those directors on the Special Committee) shall be the directors of the Surviving Corporation until the earlier of their resignation or removal or until their respective successors are duly elected and qualified, as the case may be, in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation, the DGCL and this Agreement. (b) OFFICERS. From and after the Effective Time, the officers of the Company immediately prior to the Effective Time shall be the officers of the Surviving Corporation and shall hold office until the earlier of their resignation or removal or until their respective successors are duly appointed and qualified, as the case may be, in accordance with the Certificate of Incorporation and Bylaws of the Surviving Corporation, the DGCL and this Agreement. ARTICLE II CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES; DEPOSIT; DISCLOSURE SCHEDULES SECTION 2.01 EFFECT ON CAPITAL STOCK. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any Company Common Stock or any shares of ISPH Stock: (a) CONVERSION OF COMPANY COMMON STOCK. Each share of Company Common Stock issued and outstanding immediately prior to the Effective Time (other than (i) Dissenting Shares (as defined in Section 2.04), (ii) shares of Company Common Stock that are held in the treasury of the Company or by any Subsidiary of the Company and (iii) shares of Company Common Stock then beneficially owned by the Majority Stockholder (collectively, the "EXCLUDED SHARES")) shall be converted into the right to receive from the Surviving Corporation $10.30 in cash (the "MERGER CONSIDERATION") without interest thereon upon surrender of the certificate previously representing such share of Company Common Stock as provided in Section 2.02(c). As of the Effective Time, all shares of Company Common Stock shall cease to be outstanding and shall automatically be canceled and shall cease to exist, and each certificate (a "CERTIFICATE") which immediately prior to the Effective Time represented any such share of Company Common Stock (except Excluded Shares) shall cease to have any rights with respect thereto, except the right to receive the Merger Consideration and any dividends or other distributions to which holders become entitled in accordance with this Article II upon the surrender of such Certificate. (b) CANCELLATION OF EXCLUDED SHARES. The Excluded Shares issued and outstanding immediately prior to the Effective Time shall be canceled and retired and shall cease to exist without any consideration payable therefor (subject, in the case of any Dissenting Shares, to such rights as exist pursuant to the DGCL and Section 2.04). (c) CONVERSION OF ISPH STOCK. Each share of ISPH Stock (or a fraction thereof) issued and outstanding immediately prior to the Effective Time shall be converted into one share of Common Stock, par value $0.001 per share (or a fraction thereof), of the Surviving Corporation. A-2 SECTION 2.02 PAYMENT PROCEDURES. At and after the Effective Time, each Certificate formerly representing shares of Company Common Stock (other than Excluded Shares) shall represent only the right to receive the Merger Consideration, without interest. (b) From time to time after the Effective Time, the Surviving Corporation shall deposit, or cause to be deposited, with a bank or trust company (the "PAYING AGENT"), for the benefit of the holders of the Certificates, funds in such amounts as are necessary to make the payments required pursuant to this Article II in exchange for shares of Company Common Stock (other than Excluded Shares). Any cash deposited with the Paying Agent shall hereinafter be referred to as the "EXCHANGE FUND." (c) As promptly as practicable after the Effective Time, the Surviving Corporation shall send or cause to be sent to each holder of record of shares of Company Common Stock (other than Excluded Shares) transmittal materials for use in exchanging Certificates for the Merger Consideration. The Surviving Corporation shall cause any check in respect of the Merger Consideration (together with any dividends or other distributions to which holders become entitled in accordance with this Article II upon surrender of such Certificate) which such person shall be entitled to receive to be delivered to such person upon delivery to the Paying Agent of Certificates formerly representing such shares of Company Common Stock owned by such person. In the event of a transfer of ownership of the shares of Company Common Stock that is not registered in the transfer records of the Company, payment may be made to a person other than the person in whose name the Certificate so surrendered is registered, if such Certificate shall be properly endorsed or otherwise be in proper form for transfer and the person requesting such payment shall pay any transfer or other taxes required by reason of the payment to a person other than the registered holder of such Certificate or establish to the satisfaction of the Surviving Corporation that such tax has been paid or is not applicable. No interest will be paid on any such cash to be paid pursuant to this Article II upon such delivery. The Surviving Corporation shall be entitled to deduct and withhold from the Merger Consideration otherwise payable to any holder of Certificates such amounts (if any) as the Surviving Corporation determines are required to be deducted or withheld under the Code, or any provision of United States, state or local tax law or any foreign tax law applicable as a result of the residence, location, domicile or other facts relating to such holder.

If, after the Effective Time, any such holder shall have failed to perfect or shall have effectively withdrawn or lost such right, each share of such holder's Company Common Stock shall thereupon be deemed to have been converted into and to have become, as of the Effective Time, the right to receive, without interest, the Merger Consideration, in accordance with Section 2.01(a) (together with any dividends or other distributions to which holders of Certificates become entitled in accordance with this Article II upon the surrender of such Certificates).

In each case such indemnification shall be to the full extent permitted under applicable law (and the Surviving Corporation will pay expenses in advance of the final disposition of any such action or proceeding to each such director or officer of the Company seeking indemnification hereunder to the full extent permitted by law).

The rights provided under this Section 5.08 shall be in addition to, and not in lieu of, any rights to indemnity which any party may have under the Certificate of Incorporation or Bylaws of the Company or the Surviving Corporation or any other agreements. If the Surviving Corporation or any of its successors or assigns (i) consolidates with or merges into any other corporation or entity and is not the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties or assets to any individual, corporation or any other entity, in each such case, proper provision shall be made so that the successors and assigns of the Surviving Corporation shall assume the obligations set forth in this Section 5.08.

SECTION 9.03 AMENDMENT. Subject to compliance with applicable law, this Agreement may be amended by ISPH and the Company (acting upon approval by the Special Committee) at any time before or after adoption of this Agreement by the stockholders of the Company; PROVIDED, HOWEVER, that after any adoption of this Agreement by the stockholders of the Company, no amendment shall be made which by law requires further approval by such stockholders without such further approval (including the Majority-of-Minority Condition).

INTERNATIONAL SPECIALTY PRODUCTS INC. By: /s/ RICHARD A. WEINBERG ------------------------------------ Name: Richard A. Weinberg Title: Executive Vice President and General Counsel INTERNATIONAL SPECIALTY PRODUCTS HOLDINGS INC. By: /s/ SUNIL KUMAR ------------------------------------ Name: Sunil Kumar Title: President and Chief Executive Officer A-18 ANNEX B LEHMAN BROTHERS November 8, 2002 Special Committee of the Board of Directors International Specialty Products Inc. 1361 Alps Road Wayne, NJ 07470 Members of the Special Committee of the Board: We understand that International Specialty Products Inc. (the "Company") intends to enter into an agreement with International Specialty Products Holdings Inc. ("ISPH") pursuant to which ISPH will be merged with and into the Company (the "Proposed Transaction" or the "Merger"). We also understand that Samuel J. Heyman, the Chairman of the Board of Directors of the Company, is the beneficial owner of approximately 80.9% of the shares of the Company's common stock, par value $0.01 per share (the "Company Common Stock") and is the beneficial owner of 100% of the shares of common stock of ISPH. We further understand that, upon effectiveness of the Merger, each share of Company Common Stock issued and outstanding immediately prior to the effective time of the Merger (other than (i) shares of Company Common Stock beneficially owned by Samuel J. Heyman, (ii) shares of Company Common Stock that are held in the treasury of the Company or by any subsidiary of the Company, and (iii) shares of Company Common Stock that are held by holders who have properly demanded appraisal of such shares in accordance with the Delaware General Corporation Law) will be converted into the right to receive $10.30 in cash. Based on advice of the management of the Company, we further understand that Mr. Heyman does not currently intend to sell his interest in the Company (other than as permitted pursuant to the terms of the Voting Agreement to be entered into between Mr. Heyman and the Company) or to solicit or entertain any proposals from third parties for the acquisition of the Company as, or substantially as, an entirety. The terms and conditions of the Proposed Transaction are set forth in more detail in the Agreement and Plan of Merger, dated as of November 8, 2002 (the "Agreement"), between the Company and ISPH. We have been requested by the Special Committee of the Board of Directors of the Company to render our opinion with respect to the fairness, from a financial point of view, to the Company's shareholders (other than Mr. Heyman and his affiliates) of the consideration offered to such shareholders in the Proposed Transaction. We have not been requested to opine as to, and our opinion does not in any manner address, the Company's underlying business decision to proceed with or effect the Proposed Transaction. In arriving at our opinion, we reviewed and analyzed: (1) the Agreement and the specific terms of the Proposed Transaction; (2) publicly available information concerning the Company that we believe to be relevant to our analysis, including the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2001, the Company's Quarterly Reports on Form 10-Q for the quarters ended March 31 and June 30, 2002, and the amended Schedule 13D filed by Mr. Heyman on July 9, 2002; (3) financial and operating information with respect to the business, operations and prospects of the Company furnished to us by the Company, including, without limitation, (i) certain projections of future financial performance of the Company prepared by management of the Company and provided to us on September 3, 2002 and (ii) certain updated and lower projections of future financial performance of the Company prepared by management of the Company and presented to us and the Special Committee on October 21, 2002 (the "Updated Projections"); (4) a trading history of the Company Common Stock from June 25, 1991 to the present and a comparison of that trading history with those of other companies that we deemed relevant; (5) a comparison of the historical financial results and present financial condition of the Company with those of other companies that we deemed relevant; and (6) a comparison of the financial terms of the Proposed Transaction with the financial terms of certain other recent transactions that we deemed relevant. In addition, we have had discussions with the management of the Company concerning the businesses, operations, assets, financial condition and prospects of the Company and have undertaken such other studies, analyses and investigations as we deemed appropriate. In arriving at our opinion, we have assumed and relied upon the accuracy and completeness of the financial and other information used by us without assuming any responsibility for independent verification of such information and have further relied upon the assurances of management of the Company that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. With respect to the financial projections of the Company, we have been advised by the Company that the Updated Projections have been reasonably prepared on a basis reflecting the best currently avail- B-1 able estimates and judgments of the management of the Company as to the future financial performance of the Company and, accordingly, have assumed that the Company will perform substantially in accordance with such projections. Furthermore, we have discussed the Updated Projections with the management of the Company and the Special Committee, and it has been agreed that the Updated Projections are the appropriate projections to use in performing our analysis. In arriving at our opinion, we have not conducted a physical inspection of the properties and facilities of the Company and have not made or obtained any evaluations or appraisals of the assets or liabilities of the Company. In addition, you have not authorized us to solicit, and we have not solicited, any indications of interest from any third party with respect to the purchase of all or a part of the Company's business. Our opinion necessarily is based upon market, economic and other conditions as they exist on, and can be evaluated as of, the date of this letter. Based upon and subject to the foregoing, we are of the opinion as of the date hereof that, from a financial point of view, the consideration offered to the Company's shareholders in the Proposed Transaction is fair to such shareholders (other than Mr. Heyman and his affiliates). We have acted as financial advisor to the Special Committee of the Board of Directors of the Company in connection with the Proposed Transaction and will receive a fee for our services.

WEINBERG --------------------------------- Name: Richard A. Weinberg Title: Executive Vice President and General Counsel SAMUEL J. HEYMAN /s/ SAMUEL J. HEYMAN --------------------------------- C-5 ANNEX D GENERAL CORPORATION LAW OF THE STATE OF DELAWARE SECTION 262. APPRAISAL RIGHTS. (a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to ss. 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder's shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word "stockholder" means a holder of record of stock in a stock corporation and also a member of record of a nonstock corporation; the words "stock" and "share" mean and include what is ordinarily meant by those words and also membership or membership interest of a member of a nonstock corporation; and the words "depository receipt" mean a receipt or other instrument issued by a depository representing an interest in one or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository. (b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to ss. 251 (other than a merger effected pursuant to ss. 251(g) of this title), ss. 252, ss. 254, ss. 257, ss. 258, ss. 263 or ss. 264 of this title: (1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of and to vote at the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in subsection (f) of ss. 251 of this title. (2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to ss.ss. 251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock anything except: a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof; b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or designated as a national market system security on an interdealer quotation system by the National Association of Securities Dealers, Inc. or held of record by more than 2,000 holders; c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph; or d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph. (3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under ss. 253 of this title is not owned by the parent corporation immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation. (c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable. D-1 (d) Appraisal rights shall be perfected as follows: (1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for such meeting with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) hereof that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section. Each stockholder electing to demand the appraisal of such stockholder's shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder's shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or (2) If the merger or consolidation was approved pursuant to ss.228 or ss.253 of this title, then, either a constituent corporation before the effective date of the merger or consolidation, or the surviving or resulting corporation within ten days thereafter, shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder's shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder's shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder's shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given. (e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) hereof and who is otherwise entitled to appraisal rights, may file a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder shall have the right to withdraw such stockholder's demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder's written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) hereof, whichever is later. D-2 (f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation. (g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder. (h) After determining the stockholders entitled to an appraisal, the Court shall appraise the shares, determining their fair value exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. In determining the fair rate of interest, the Court may consider all relevant factors, including the rate of interest which the surviving or resulting corporation would have had to pay to borrow money during the pendency of the proceeding. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, permit discovery or other pretrial proceedings and may proceed to trial upon the appraisal prior to the final determination of the stockholder entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting corporation pursuant to subsection (f) of this section and who has submitted such stockholder's certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section. (i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Interest may be simple or compound, as the Court may direct. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court's decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state. (j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney's fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal. (k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder's demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just. (l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.
