During the loan period, the Borrowed Employee will be the borrowed servant of the Issuer and the Issuer will have direct and sole control of the Borrowed Employee, assign work duties to the Borrowed Employee and provide day-to-day supervision of the Borrowed Employee. Alticor Inc. will continue to process and pay the Borrowed Employee’s wages and other compensation, withhold, collect, report and/or remit applicable taxes, make other deductions and, to the extent permitted by its employee benefit plans and applicable law, provide benefits to the Borrowed Employee under its employee benefit plans.

CUSIP NO. 458738101

SCHEDULE 13D

Page 11 of 14

Alticor Inc., Solstice Holdings Inc., and Alticor Global Holdings Inc., may be deemed to beneficially own the same 34,963,066 shares of the Issuer’s stock.

The number of shares reported in this Item 5(a) includes 5,941,024 shares of Common Stock owned directly by Pyxis, 28,160,200 shares of Common Stock issuable to Pyxis upon conversion of its 5,000,000 shares of Series A Preferred Stock and 861,842 shares of Common Stock issuable to Pyxis upon conversion of the convertible notes (as of September 30, 2007) described in Amendment No. 1. In determining Pyxis’ beneficial ownership percentage above, a division calculation is used wherein 34,963,066 is the numerator and the denominator is equal to the sum of: (a) all shares of Common Stock outstanding (as reported by the Issuer) plus 3,190,987 shares of Common Stock which were issued upon conversion of the convertible notes as described herein, (b) 28,160,200 shares reserved for issuance upon the conversion of the Series A Preferred Stock, and (c) 861,842 shares reserved for issuance upon the conversion of the remaining convertible notes.

The calculations in this Item 5(a) are based on the Issuer having 27,639,120 shares of Common Stock outstanding as of September 30, 2007, as reported in the Issuer’s most recent Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission. In addition, these calculations assume no outstanding options or other rights to obtain Common Stock have been exercised by their holders except for the conversion of the convertible notes by Pyxis as described herein or as otherwise indicated by the Issuer.

None of the other persons named in response to Item 2 of this Schedule 13D is the beneficial owner of the Common Stock except to the extent beneficial ownership of shares owned by Pyxis may be attributed to such person.

(b) Pyxis holds the sole power to vote and dispose of the securities of Issuer that it holds. Alticor Inc., Solstice Holdings Inc., and Alticor Global Holdings Inc. have the power to direct the voting and disposition of the securities of the Issuer held by Pyxis by virtue of their direct or indirect control of Pyxis.

(c) On December 17, 2007, Pyxis elected to convert $2,039,679.43 of convertible notes, consisting of the original principal amount of the convertible notes of $2,000,000 plus accrued and unpaid interest thereon, into shares of Common Stock at a conversion price per share of Common Stock equal to $0.6392. As a result of the election, 3,190,987 shares of Common Stock of Issuer were issued to Pyxis. Except as described above, there have been no transactions in the Issuer’s Common Stock by any of the reporting persons during the past sixty days.
