Re: Initial Public Offering

Ladies and Gentlemen:

This letter is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and between Orbit Acquisition Corp., a Delaware corporation (the “Company”) and JPMorgan Securities Inc., as representative of the several underwriters (the “Underwriters”), relating to an underwritten initial public offering (the “Offering”), of 25,000,000 of the Company’s units (the “Units”), 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 (each, a “Warrant”). The Units sold in the Offering will be listed and traded on the American Stock Exchange pursuant to a Registration Statement on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange Commission (the “SEC”). Certain capitalized terms used herein are defined in paragraph 14 hereof.

In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Offering and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Orbit Holdings, LLC (the “Sponsor”), and each of Gabriel Nechamkin, Lief Rosenblatt and Mark Sonnino (the “Managing Members”) for purposes of paragraphs 4(d), 13 and 15 only, hereby agree with the Company as follows:

1. The Sponsor agrees that (i) in connection with a vote to approve any proposed Initial Business Combination or an amendment to the Company’s amended and restated certificate of incorporation to provide for an Extension Period, as the case may be, it shall (a) vote all shares of Founders’ Common Stock owned by it in accordance

with the majority of the votes cast by the Public Stockholders and (b) vote any shares of Common Stock acquired by it in the Offering or the secondary public market in favor of any proposed Initial Business Combination or an amendment to the Company’s amended and restated certificate of incorporation to provide for an Extension Period, as the case may be, and (ii) it shall vote all shares of Common Stock (including the Founders’ Common Stock) owned by it in favor of an amendment to the Company’s amended and restated certificate of incorporation providing for the Company’s perpetual existence in connection with a vote to approve a proposed Initial Business Combination. The Sponsor also acknowledges and agrees that it will not have any conversion rights with respect to the shares of Founders’ Common Stock owned or with respect to any shares of Common Stock acquired in or following the Offering by it.

2. The Sponsor hereby agrees that in the event that the Company fails to consummate an Initial Business Combination within 24 months after the date of the final Prospectus relating to the Offering (or within any Extension Period), the Sponsor shall take all reasonable steps to (a) cause the Trust Account to be liquidated and distributed to the holders of Common Stock purchased in the Offering as soon as reasonably practicable and (b) cause the Company to be dissolved and liquidated as soon as reasonably practicable. The Sponsor agrees that in connection with any cessation of the corporate existence of the Company, it will take all reasonable steps to cause the Company to adopt a plan of dissolution and distribution in accordance with Section 281(b) of the General Corporation Law of the State of Delaware or any successor provision thereto.

3. The Sponsor hereby waives any right, title, interest or claim of any kind in or to any distributions of the Trust Account as a result of any liquidation of the Company with respect to the Founders’ Common Stock. The Sponsor hereby waives any claim the Sponsor may have in the future against the Trust Account, and will not seek recourse against the funds held in or distributed from the Trust Account prior to an Initial Business Combination, in either case on account of, or arising out of, any contracts or agreements with the Company.

4. (a) In the event of the liquidation of the Trust Account, the Sponsor shall (i) in the event that the Company’s assets not held in the Trust Account are insufficient to pay the costs of the liquidation, advance to the Company the funds necessary to complete the liquidation and will not seek repayment from the Company for such amounts and (ii) indemnify and hold harmless the Company, against claims of prospective target businesses, vendors for services rendered or products sold to the Company or third parties, including lenders, with whom the Company enters into contractual relationships following the consummation of the Offering to the extent necessary to ensure that such claims do not reduce the amount of funds in the Trust Account, or to the extent necessary to satisfy any required return or disgorgement of payments made from the Trust Account to the beneficiaries of the Trust Account, but

only if such prospective target business, vendor or third party has not executed an agreement waiving claims against the Trust Account; provided, however, that such indemnity shall not apply as to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended.

(b) The Sponsor will have the right to defend against any such claim with counsel of their choice reasonably satisfactory to the Company if within 15 days following written receipt of notice of the claim to the Sponsor, the Sponsor notifies the Company in writing that the Sponsor will undertake such defense.

(c) The Sponsor hereby represents that it is an “accredited investor” as that term is defined in Rule 501 of Regulation D promulgated by the SEC under the Securities Act of 1933, as amended, and the Sponsor further represents that it has sufficient funds available to it to satisfy its indemnification obligations under this paragraph 4.

(d) The Managing Members of the Sponsor agree to take such reasonable actions as may be necessary to enable the Sponsor to comply with its obligations under this paragraph 4, including the contribution of additional capital to the Sponsor, arranging for financing for the Sponsor, or a combination of the two.

5. To the extent that the Underwriters do not exercise their over-allotment option to purchase an additional 3,750,000 Units of the Company (as described in the Prospectus), the Sponsor agrees that it shall return to the Company for cancellation, at no cost, a number of Founders’ Units held by the Sponsor determined by multiplying [_______] by a fraction, (i) the numerator of which is 3,750,000 minus the number of shares of Common Stock purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 3,750,000.

6. (a) The Sponsor shall not without the prior written consent of the Underwriters with respect to the Offering (i) sell, offer to sell, contract or agree to sell, assign, hypothecate, donate, pledge, grant any security interest in, encumber, grant any option to purchase or otherwise dispose of or agree to dispose of (or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Sponsor or any affiliate of the Sponsor or any person in privity with the Sponsor), directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Securities and Exchange Commission (the “SEC”) in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Securities
