Exhibit 10.3

SECURITIES ESCROW AGREEMENT

This SECURITIES ESCROW AGREEMENT is made as of [    ], 2008 (the “Agreement”), by and among iStar Acquisition Corp., a Delaware corporation (the “Company”), each of the parties set forth in Exhibit A hereto (collectively the “Private Investors”) and Continental Stock Transfer & Trust Company, a New York corporation (the “Escrow Agent”).

WHEREAS, the Company has entered into an Underwriting Agreement, dated [    ], 2008 (the “Underwriting Agreement”), with Banc of America Securities LLC, acting as representative of the underwriters (the “Underwriters”), relating to an underwritten initial public offering (the “IPO”) of 50,000,000 units (the “Units”) of the Company, each comprised of one share of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), and one warrant exercisable for one share of Common Stock (the “Warrant”), all as more fully described in the Company’s final Prospectus, dated [    ] (the “Prospectus”), which forms a part of the Company’s Registration Statement on Form S-1 (File No. 333-147305) filed under the Securities Act of 1933, as amended (the “Registration Statement”), and declared effective by the Securities and Exchange Commission on  [    ], 2008 (the “Effective Date”).

WHEREAS, each of the Private Investors has agreed as a condition of the Underwriters’ purchase of the Units to deposit its Units purchased on the date set forth opposite each Private Investor’s name on Exhibit A hereto (the “Initial Units”), in escrow as hereinafter provided;

WHEREAS, the Private Investors have agreed as a condition of the Underwriters’ purchase of the Units in the IPO to purchase an aggregate of 10,000,000 Warrants for $1.00 per Warrant (the “Private Placement Warrants”) and an aggregate of 2,500,000 Units for $10.00 per Unit (the “Private Placement Units,” together with the Private Placement Warrants, the “Private Placement Securities” and, collectively with the Initial Units and the Private Placement Warrants, the “Escrow Securities”) immediately prior to and subject to the completion of the IPO and to deposit the Private Placement Securities in escrow as hereinafter provided; and

WHEREAS, the Company and the Private Investors desire that the Escrow Agent accept the Escrow Securities, in escrow, to be held and disbursed as hereinafter provided.

IT IS AGREED:

1.             Appointment of Escrow Agent.  The Company and the Private Investors hereby appoint the Escrow Agent to act in accordance with and subject to the terms of this Agreement and the Escrow Agent hereby accepts such appointment and agrees to act in accordance with and subject to such terms.

2.             Deposit of Escrow Securities.  Promptly following the completion of the IPO, the Private Investors shall deliver to the Escrow Agent certificates representing their respective Escrow Securities as set forth opposite their respective names on Exhibit A hereto, which certificates shall remain in the name of such Private Investor or in the name of such Private Investor’s Permitted Transferee (defined below), to be held and disbursed subject to the terms and conditions of this Agreement.  Each Private Investor acknowledges that the certificate representing such Private Investor’s Escrow Securities bears a legend to reflect the deposit of such Escrow Securities under this Agreement.

3.             Disbursement of the Escrow Securities.  The Escrow Agent shall hold the Initial Units until the first anniversary of the consummation of a Business Combination (as such term is defined in the Amended and Restated Articles of Incorporation of the Company and as the same may be amended from time to time) and shall hold the Private Placement Securities until the consummation of a Business Combination (each such period, an “Escrow Period”); provided, however, that if the over-allotment

option granted to the Underwriters pursuant to the Underwriting Agreement is not exercised in full or in part prior to the expiration of the over-allotment option, then the Escrow Agent shall release to the Company such number of Initial Units as directed in writing by the Company.  The Company shall promptly provide notice of the consummation of a Business Combination to the Escrow Agent.  Upon the completion of each Escrow Period, the Escrow Agent shall automatically disburse the applicable Escrow Securities to each Private Investor upon receipt of written request therefor from the Company; provided, however, that if the Escrow Agent is notified by the Company pursuant to Section 6.7 hereof that the Company is being liquidated at any time during the Escrow Period, then the Escrow Agent shall promptly destroy the certificates representing the Escrow Securities and; provided further, that if, after the Company consummates a Business Combination and the Company or the surviving entity of such Business Combination subsequently consummates a liquidation, merger, stock exchange or other similar transaction which results in all of the security holders of the Company or such entity having the right to exchange their securities for cash, securities or other property, then the Escrow Agent will, upon receipt of a certificate, executed by the Chief Executive Officer of the Company, in form reasonably acceptable to the Escrow Agent, that such transaction is then being consummated, release the Escrow Securities to the Private Investors immediately prior and subject to consummation of the transaction so that they can similarly participate.  The Escrow Agent shall act as soon as reasonably possible following the receipt of the certificate.  The Escrow Agent shall have no further duties hereunder with respect to the Escrow Securities after the disbursement or destruction of the Escrow Securities in accordance with this Section 3.

4.             Rights of Private Investors in Escrow Securities.

4.1           Voting Rights as a Stockholder.  Subject to the terms of their respective Letter Agreements as described in Section 4.4 hereof and except as herein provided, each Private Investor shall retain all of its rights as a stockholder of the Company with respect to shares of Common Stock included in the Escrow Securities during the Escrow Period, including, without limitation, the right to vote Common Stock.

4.2           Dividends and Other Distributions in Respect of the Escrow Securities.  During the Escrow Period, all dividends payable in cash with respect to the Escrow Securities shall be paid to the Private Investors, but all dividends payable in stock or other non-cash property (the “Non-Cash Dividends”) shall be delivered to the Escrow Agent to hold in accordance with the terms hereof.  As used herein, the term “Escrow Securities” shall be deemed to include the Non-Cash Dividends distributed thereon, if any.
