Item 1. Security and Issuer ------------------- This statement on Schedule 13D (the "Schedule 13D") relates to shares of common stock, $0.001 par value (the "Common Stock"), of Phase III Medical, Inc., a Delaware corporation (the "Company"). The principal executive offices of the Company are located at 330 South Service Road, Suite 120, Melville, New York 11747. Item 2. Identity and Background ----------------------- This Schedule 13D is being filed by Mark Weinreb ("Mr. Weinreb"). Mr. Weinreb is a citizen of the United States. The business address of Mr. Weinreb is 330 South Service Road, Suite 120, Melville, New York 11747. Mr. Weinreb currently serves as the Chief Executive Officer of the Company. The Company's principal executive offices are located at 330 South Service Road, Suite 120, Melville, New York 11747. Mr. Weinreb has not, during the last five years, (a) been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction as a result of which such entity or person was or is now subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. Item 3. Source and Amount of Funds or Other Consideration ------------------------------------------------- On May 4, 2005, the Company's Board of Directors approved an amendment to the employment agreement between the Company and Mr. Weinreb, dated February 6, 2003 (the "Employment Agreement"), which was approved by the shareholders on July 20, 2005, to grant Mr. Weinreb 3,000,000 shares of Common Stock as partial consideration for services provided by Mr. Weinreb as Chief Executive Officer. 1,000,000 of such shares vested and became exercisable immediately upon the date of grant, and 1,000,000 of such shares vest and become exercisable on each of the first and second anniversaries of the date of grant. The Board of Directors also granted to Mr. Weinreb, and the shareholders approved, options to purchase up to 4,000,000 shares of Common Stock (the "July Option") pursuant to the Company's 2003 Equity Participation Plan (the "2003 EPP"), of which 2,000,000 options vested and became exercisable immediately upon the date of grant. The July Option is an Incentive Stock Option pursuant to Section 422 of the Code, and is represented by a stock option agreement. The July Option has an exercise price equal to $0.06 per share and vests and becomes exercisable as to 1,000,000 shares on each of the first and second anniversaries of the date of grant and remains exercisable as to any vested portion thereof in accordance with the terms of the 2003 EPP and the stock option agreement. If Mr. Weinreb pays the exercise price of the July Option with shares of Common Stock, the plan committee appointed by the Board of Directors may, in its discretion, grant Mr. Weinreb an option with a reload feature, pursuant to which a reload stock option, which would be granted at the same time that payment is received on the option exercise, would grant Mr. Weinreb the option to purchase (i) the number of shares of Common Stock equal to the sum of the number of shares used to exercise the July Option (or the number of shares not received if Mr. Weinreb paid the option price by receiving a reduced number of shares on exercise), or (ii) in the case of non-qualified stock options, the number of shares of Common Stock used to satisfy any tax withholding requirement related to the exercise of such option. Item 4. Purpose of Transaction ---------------------- The acquisition of the securities described in Item 3 by Mr. Weinreb is for investment purposes.

On February 6, 2003, Mr. Weinreb was appointed President and Chief Executive Officer of the Company pursuant to the terms of the Employment Agreement. The Employment Agreement has an initial term of three years, with automatic annual extensions unless terminated by the Company or Mr. Weinreb at least 90 days prior to an applicable anniversary date. The Company has agreed to pay Mr. Weinreb an annual salary of $180,000 for the initial year of the term, $198,000 for the second year of the term, and $217,800 for the third year of the term. In addition, he is entitled to an annual bonus in the amount of $20,000 for the initial year in the event, and concurrently on the date, that the Company has received debt and/or equity financing in the aggregate amount of at least $1,000,000 since the beginning of his service, and $20,000 for each subsequent year of the term, without condition. In addition, the Company, pursuant to the 2003 EPP, entered into a stock option agreement with Mr. Weinreb (the "Initial Option Agreement"). Under the Initial Option Agreement, the Company granted Mr. Weinreb the right and option, exercisable for 10 years, to purchase up to 2,500,000 shares of the Company's Common Stock at an exercise price of $0.03 per share and otherwise upon the terms set forth in the Initial Option Agreement. In addition, in the event that the closing price of the Company's Common Stock equals or exceeds $0.50 per share for any five consecutive trading days during the term of the employment agreement (whether during the initial term or an annual extension), the Company has agreed to grant to Mr. Weinreb, on the day immediately following the end of the five day period, an option for the purchase of an additional 2,500,000 shares of the Company's Common Stock for an exercise price of $0.50 per share, pursuant to the 2003 EPP and a stock option agreement to be entered into between the Company and Mr. Weinreb containing substantially the same terms as the Initial Option Agreement, except for the exercise price and that the option would be treated as an "incentive stock option" for tax purposes only to the maximum extent permitted by law (the "Additional Option Agreement"). The Company agreed to promptly file with the Securities and Exchange Commission a Registration Statement on Form S-8 (the "Registration Statement") pursuant to which the issuance of the shares covered by the 2003 EPP, as well as the resale of the Common Stock issuable upon exercise of the Initial Option Agreement, are registered, which has been filed. Additionally, the Company has agreed, following any grant under the Additional Option Agreement, to promptly file a post-effective amendment to the Registration Statement pursuant to which the Common Stock issuable upon exercise thereof shall be registered for resale. Mr. Weinreb has agreed that he will not resell publicly any shares of the Company's Common Stock obtained upon exercise of the Initial Option Agreement or the Additional Option Agreement prior to the first anniversary of the date of the employment agreement. On May 4, 2005, the Company's Board of Directors approved, which was approved by the shareholders on July 20, 2005, an amendment to Mr. Weinreb's Employment Agreement, to (a) extend the expiration date thereof from February 2006 to December 2008; (b) change Mr. Weinreb's annual base salary of $217,800 (with an increase of 10% per annum) to an annual base salary of $250,000 (with no increase per annum); (c) grant Mr. Weinreb 3,000,000 shares of Common Stock, 1,000,000 shares of which shall vest on each of the date of grant and the first and second anniversaries of the date of grant; (d) amend the severance provision of the existing Employment Agreement to provide that in the event of termination without cause (subject to certain exceptions), Mr. Weinreb will be entitled to receive a lump sum payment equal to his then base salary and automobile allowance for a period of one year; (e) commencing in August 2006, increase Mr. Weinreb's annual bonus from $20,000 to $25,000; (f) in August 2005, pay Mr. Weinreb $15,000 to cover costs incurred by him on behalf of the Company; and (g) in 2006, provide for the reimbursement of all premiums in an annual aggregate amount of up to $18,000 payable by Mr. Weinreb for life and long term care insurance covering each year during the remainder of the term of his employment.
