SCHEDULE -------------------------------------------------------------------------------- CUSIP NO. 456910306 13D Page 4 of 6 Pages Item 3. Source and Amount of Funds or Other Consideration. Beneficial ownership (as such term is defined under Rule 13d-3 of the Securities Exchange Act of 1934, as amended) of 7,304,871 Shares were acquired pursuant to various convertible notes issued by the Company to Dr. Robbins in 2003 and 2004 in loan transactions (the "Robbins Notes") to fund the Company's working capital requirements in the aggregate amount of $365,244, including aggregate principal of $314,000 and accrued interest through March 31, 2006 of $51,244. The Robbins Notes mature on January 1, 2016. Dr. Robbins' source of funds for the loans to the Company was his personal funds. To that extent that the amount of accrued interest payable increases, the number of shares acquired pursuant to the various convertible notes will increase. Item 4. Purpose of the Transaction. The Robbins Notes are held by Dr. Robbins for the purpose of investment. Except as otherwise disclosed herein, Dr. Robbins is not considering any plans or proposals which relate to or would result in any of the following: (a) the acquisition by any person of additional securities of the Company, or the disposition of securities of the Company; (b) an extraordinary corporate transaction, such as a merger, reorganization, or liquidation, involving the Company or any of its subsidiaries; (c) a sale or transfer of any material amount of assets of the Company or any of its subsidiaries; (d) any change in the Company's Board of Directors or management; (e) any material change in the present capitalization or dividend policy of the Company; (f) any material change in the Company's business, corporate structure, charter or bylaws; (g) any change which would impede the acquisition of control of the Company by any person; (h) causing any class of securities of the Company to be delisted; (i) the Company's common stock to be eligible to the deregistered under the Securities Exchange Act of 1934; or (j) any actions similar to those enumerate above. Item 5. Interest in Securities of the Issuer. (a) Subject to certain limitations described Item 6 below, the aggregate number of Shares that may be deemed to be beneficially owned by Dr. Robbins are 7,364,038 Shares, of which (i) 7,304,871 are issuable upon the conversion of the Robbins Notes (including principal in the amount of $314,000 and accrued interest in the amount of $51,244 through March 31, 2006) and (ii) 59,167 are issuable upon the exercise of options to purchase Shares. The 7,364,038 Shares represent approximately 27.1% of the total outstanding Shares as of March 31, 2006. The percentage of outstanding Shares beneficially owned by Dr. Robbins are based upon the aggregate of 27,220,919 outstanding Shares consisting of (x) 19,856,881 Shares outstanding as of March 31, 2006, (y) 7,304,871 Shares underlying the Robbins Notes and (z) 59,167 options to purchase Shares. SCHEDULE -------------------------------------------------------------------------------- CUSIP NO. 456910306 13D Page 5 of 6 Pages (b) Upon conversion of the Robbins Notes, Dr. Robbins would have the sole power to vote or to direct the vote, and sole power to dispose or to direct the disposition of all the Shares which underlie the Robbins Notes. (c) Dr. Robbins effected no transactions in the Shares during the past 60 days. (d) Except as stated within this Item 5, only Dr. Robbins has the right to direct the receipt of dividends from, or proceeds from the sale of, the Shares reported by this statement. To the knowledge of Dr. Robbins, only he has the right to receive dividends, or proceeds, from the sale of the Shares reported by this statement. (e) Not applicable. Item 6. Contracts, Arrangements, Understanding or Relationships with Respect to Securities of the Issuer. The Robbins Notes are currently convertible into Shares subject to the following limitations: 1. The Shares issuable upon a proposed conversion can not result in a change in control of the Company which would limit the use of its net operating loss carryforwards; provided, however, if the Company closes a transaction with another third party or parties that results in a change of control which will limit the use of its net operating loss carryforwards, then the change of control provision shall no longer be in effect. The Company estimates that at December 31, 2005, up to approximately 11,000,000 Shares could be issued as a result of conversions of principal and accrued interest before a change of control would be deemed to occur that would limit the use of the Company's net operating loss carryforwards. 2. Prior to any conversion by Dr. Robbins, other note holders holding notes which are then convertible into 5% or more of the Company's then outstanding Shares shall be entitled to participate on a pari passu basis with Dr. Robbins and upon any such participation Dr. Robbins shall proportionately adjust his conversion request such that, in the aggregate, a change of control which would limit the use of the Company's net operating loss carryforwards does not occur.
