Re: Initial Public Offering

Gentlemen:

This letter (“Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into, or proposed to be entered into, by and between SCG Financial Acquisition Corp., a Delaware corporation (the “Company”), and Lazard Capital Markets LLC, as representative of the several underwriters (the “Underwriters”), relating to an underwritten initial public offering (the “Offering”), of 10,000,000 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 shall be quoted and traded on the Over-the-Counter Bulletin Board pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the Securities and Exchange Commission (the “Commission”). Certain capitalized terms used herein are defined in paragraph 15 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, SCG Financial Holdings, LLC (the “Sponsor”), each of the members of the Sponsor (each, a “Member” and collectively, the “Members”), and Xxxxxxx X. Xxxxx (the “Founder”), hereby agree with the Company as follows:

1. Each of the undersigned hereby agrees that if the Company seeks stockholder approval of a proposed Business Combination, then in connection with such proposed Business Combination, he or it shall vote all Founder Shares and any shares acquired by him or it in the Offering or the secondary public market in favor of such proposed Business Combination.

2. (a) Each of the undersigned hereby agrees that in the event that the Company fails to consummate a Business Combination within 21 months from the closing of the Offering (or 24 months from the date of the closing of the Offering if the Company executes a letter of intent, agreement in principle or definitive agreement relating to a proposed initial Business Combination before such 21-month period ends), he or it shall take all reasonable steps to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible, redeem the Common Stock held by the Public Stockholders, at a per-share price, payable in cash, equal to the aggregate amount including interest then on deposit in the Trust Account, but net of any taxes payable and up to $100,000 of such net interest to pay reasonable expenses of dissolution, divided by the number of shares of Common Stock then outstanding, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and other requirements of applicable law.

(b) Each of the undersigned acknowledges that the undersigned has no right, title, interest or claim of any kind in or to any monies held in the Trust Account or any other asset of the Company as a result of any liquidation of the Trust Account with respect to the Founder Shares. Each of the undersigned hereby further waives, with respect to any shares of the Common Stock held by him or it, any redemption rights he or it may have in connection with the consummation of a Business Combination, including, without limitation, any such rights available in the context of a stockholder vote to approve such Business Combination or in the context of a tender offer made by the Company to purchase shares of the Common Stock (although the undersigned shall be entitled to redemption and liquidation rights with respect to any shares of the Common Stock (other than the Founder Shares) the undersigned holds if the Company fails to consummate a Business Combination within 21 months from the date of the Prospectus (or 24 months from the date of the Prospectus if the Company executes a letter of intent, agreement in principle or definitive agreement relating to a proposed initial Business Combination before such 21-month period ends)).

3. (a) To the extent that the Underwriters do not exercise their over-allotment option to purchase an additional 1,500,000 shares of Common Stock (as described in the Prospectus), the Sponsor shall return to the Company for cancellation, at no cost, the number of Founder Shares held by the Sponsor determined by multiplying 285,715 by a fraction: (i) the numerator of which is 1,500,000 minus the number of shares of the Common Stock purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 1,500,000. The Sponsor further agrees that to the extent that: (a) the size of the Offering is increased or decreased and (b) the Sponsor has either purchased or sold shares of the Common Stock or an adjustment to the number of Founder Shares has been effected by way of a stock split, stock dividend, reverse stock split, contribution back to capital or otherwise, in each case in connection with such increase or decrease in the size of the Offering, then, (i) the references to 1,500,000 in the numerator and denominator of the formula in the immediately preceding sentence shall be changed to a number equal to 15% of the number of shares included in the Units issued in the Offering and (ii) the reference to 285,715 in the formula set forth in the immediately preceding sentence shall be adjusted to such number of shares of the Common Stock that the Sponsor would have to return to the Company in order to hold 16% of the Company’s issued and outstanding shares after the Offering (assuming the Underwriters do not exercise their over-allotment option). In addition, a portion of the Founder Shares held by the Sponsor in an amount equal to 3.0% of the Company’s issued and outstanding shares immediately after the Offering shall be returned to the Company for cancellation, at no cost, in the event that the last sales price of the Company’s stock does not equal or exceed $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for at least one period of 20 trading days within any 30-trading day period within 24 months following the closing of the Company’s initial Business Combination.

(b) In the case of any of the Founder Shares owned by the Sponsor that are not subject to forfeiture pursuant to paragraph 3(a) above, until (A) one year after the completion of the Company’s initial Business Combination or earlier if, subsequent to the Company’s initial Business Combination (such applicable period being the “Founder Lock-Up Period”), the last sales price of the Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for at least one period of 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s initial Business Combination or (B) the Company consummates a subsequent liquidation, merger, stock exchange or other similar transaction which results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other property, and in the case of any of the Founder Shares owned by the Sponsor that are subject to forfeiture pursuant to paragraph 3(a) above, the undersigned shall not, except as described in the Prospectus, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, 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 Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder, with respect to the Founder Shares, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any of the Founder Shares, whether any such transaction is to be settled by delivery of the Common Stock or such other securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in clause (i) or (ii).

(c) Until 30 days after the completion of the Company’s initial Business Combination (“Sponsor Lock-Up Period”), each of the undersigned shall not, except as described in the Prospectus, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, 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 Exchange Act of 1934, as amended, and the rules and regulations of the SEC promulgated thereunder, with respect to the Sponsor Warrants and the respective Common Stock underlying the Sponsor Warrants, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any of the Sponsor Warrants and the respective Common Stock underlying the Sponsor Warrants, whether any such transaction is to be settled by delivery of the Common Stock or such other securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in clause (i) or (ii).

(d) Notwithstanding the provisions contained in paragraphs 3(b) and 3(c) herein, the Sponsor may transfer the Founder Shares and/or Sponsor Warrants and the respective shares of Common Stock underlying the Sponsor Warrants: (i) to the Company’s officers or directors, any affiliate or family member of any of the Company’s officers or directors or any affiliate of the Sponsor; (ii) by gift to a member of the Founder’s immediate family or to a trust, the beneficiary of which is a member of the Founder’s immediate family, an affiliate of the Founder or to a charitable organization; (iii) in the case of the Founder, by virtue of the laws of descent and distribution upon death of the Founder; (iv) pursuant to a qualified domestic relations order; (v) by virtue of the laws of the state of Delaware or the Sponsor’s limited liability company agreement upon dissolution of the Sponsor; (vi) in the event of the Company’s liquidation prior to the completion of the Company’s initial Business Combination; or (vii) in the event that the Company consummates a liquidation, merger, stock exchange or other similar transaction that results in all of its stockholders having the right to exchange their shares of the Common Stock for cash, securities or other property subsequent to the consummation of the Company’s initial Business Combination; provided, however, that, in the case of clauses (i) through (v), these permitted transferees enter into a written agreement with the Company agreeing to be bound by the transfer restrictions in paragraphs 3(b) and 3(c) herein.

(e) Further, each of the undersigned agrees that after the Founder Lock-Up Period or the Sponsor Lock-Up Period, as applicable, has elapsed, the Founder Shares and/or Sponsor Warrants and the respective shares of Common Stock underlying the Sponsor Warrants owned by the undersigned shall only be transferable or saleable pursuant to a sale registered under the Securities Act or pursuant to an available exemption from registration under the Securities Act. The Company and the undersigned each acknowledge that pursuant to that certain registration rights agreement to be entered into between the Company and the Sponsor, the Sponsor may request that a registration statement relating to the Founder Shares and/or Sponsor Warrants and the respective shares of Common Stock underlying the Sponsor Warrants be filed with the Commission prior to the end of the Founder Lock-Up Period or the Sponsor Lock-Up Period, as the case may be; provided, however, that such registration statement does not become effective prior to the end of the Founder Lock-Up Period or the Sponsor Lock-Up Period, as applicable.

(f) The undersigned shall retain all of its rights as a shareholder during the Share Lockup Period including, without limitation, the right to vote such shares.

(e) During the Share Lockup Period and Warrant Lockup Period, all dividends payable in cash with respect to such securities shall be paid to the undersigned, but all dividends payable in Common Stock or other non-cash property shall become subject to the applicable lockup period as described herein and shall be released from such lockup in accordance with the provisions of this Paragraphs 3.

4. Without limiting the provisions of paragraph 3 hereof, during the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, each of the undersigned shall not (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose of, directly or indirectly, 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 Exchange Act of 1934, as amended, and the rules and regulations of the Commission promulgated thereunder, with respect to any Units, shares of Common Stock, Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by the undersigned, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Units, shares of Common Stock, Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by the undersigned, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce any intention to effect any transaction specified in clause (i) or (ii).

5. In the event of the liquidation of the Trust Account without the consummation of a Business Combination, the Founder agrees to indemnify and hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) to which the Company may become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company or (ii) a prospective target business with which the Company has entered into an acquisition agreement with (a “Target”); provided, however, that such indemnification of the Company by the Founder shall apply only to the extent necessary to ensure that such claims by a third party for services rendered (other than the Company’s independent public accountants) or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below $10.00 (or $9.97 if the over-allotment is exercised in full) per share of the Common Stock sold in the Offering (the “Offering Shares”), and provided, further, that only if such third party or Target has not executed an agreement waiving claims against and all rights to seek access to the Trust Account whether or not such agreement is enforceable. In the event that any such executed waiver is deemed to be unenforceable against such third party, the Founder shall not be responsible for any liability as a result of any such third party claims. Notwithstanding any of the foregoing, such indemnification of the Company by the Founder shall not apply as to any claims under the Company’s obligation to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended. The Founder shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the undersigned, the undersigned notifies the Company in writing that the Founder shall undertake such defense.

6. (a) In order to minimize potential conflicts of interest that may arise from multiple corporate affiliations, the Founder hereby agrees that until the earliest of the Company’s initial Business Combination, liquidation or such time as he ceases to be an officer or director of the Company, he shall present to the Company for its consideration, prior to presentation to any other entity, any business opportunity with an enterprise value of $80 million or more, subject to any pre-existing fiduciary or contractual obligations he might have.

(b) Each of the undersigned understands that the Company may effect a Business Combination with a single target business or multiple target businesses simultaneously and agrees that the undersigned will not participate in the formation of, or become an officer or director of, any blank check company, until the Company has entered into a definitive agreement regarding its initial Business Combination or the Company has failed to complete an initial Business Combination within 21 months (or 24 months if a letter of intent, agreement in principle or definitive agreement relating to a prospective Business Combination is executed before the 21-month period ends), from the closing of the Offering; provided, however, that nothing contained herein shall override the undersigned’s fiduciary obligations to any entity with which the undersigned is currently directly or indirectly associated or affiliated or by whom the undersigned is currently employed.

(c) Each of the undersigned hereby agrees and acknowledges that (i) each of the Underwriters and the Company would be irreparably injured in the event of a breach by the undersigned of his or its obligations under paragraphs 6(a) and/or 6(b) hereof, (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event of such breach.

7. The Founder’s biographical information furnished to the Company is true and accurate in all material respects and does not omit any material information with respect to the Founder’s background. Each of the questionnaires furnished to the Company by the Sponsor and the Founder are true and accurate in all material respects. The undersigned represents and warrants that:

(a) the undersigned is not subject to or a respondent in any legal action for, any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering of securities in any jurisdiction;

(b) the undersigned has never been convicted of, or pleaded guilty to, any crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to any dealings in any securities and the undersigned is not currently a defendant in any such criminal proceeding; and

(c) the undersigned has never been suspended or expelled from membership in any securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked.

8. Except as disclosed in the Prospectus, neither the undersigned nor any affiliate of the undersigned, shall receive any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment of a loan or other compensation prior to, or in connection with any services rendered in order to effectuate the consummation of the Company’s initial Business Combination (regardless of the type of transaction that it is), other than the following:

(a) repayment of loans made to the Company by Sachs Capital Group in connection with the preparation, filing and consummation of the Offering;

(b) payment of an aggregate of $7,500 per month to Sachs Capital Group LP, an affiliate of the Founder, for office space, secretarial and administrative services;

(c) payment of up to $7,500 in monthly additional overhead expenses incurred on the Company’s behalf by Sachs Capital Group LP or the Sponsor; and

(d) repayment of loans, if any, and on such terms as to be determined by the Company from time to time, made by the Sponsor or an affiliate of the Sponsor or certain of the Company’s officers and directors to finance transaction costs in connection with an intended initial Business Combination, provided, that, if the Company does not consummate an initial Business Combination, a portion of the working capital held outside the Trust Account may be used by the Company to repay such loaned amounts so long as no proceeds from the Trust Account are used for such repayment.

9. In the event that the Company does not consummate a Business Combination and must liquidate and its remaining net assets are insufficient to complete such liquidation, the Founder agrees to advance such funds necessary to complete such liquidation and agrees not to seek repayment for such expenses. The Founder represents to the Company that he is capable of funding a shortfall in the Trust Account to satisfy his reasonably foreseeable indemnification obligations.

10. Each of the undersigned acknowledges and understands that the Underwriters and the Company will rely upon the agreements, representations, and warranties set forth herein in proceeding with the Offering.

11. The undersigned authorizes any employer, financial institution, or consumer credit reporting agency to release to the Representatives and its legal representatives or agents (including any investigative search firm retained by the Representatives) any information they may have about the undersigned’s background and finances (“Information”), purely for the purposes of the Offering (and shall thereafter hold such information confidential). Neither the Representatives nor its agents shall be violating the undersigned’s right of privacy in any manner in requesting and obtaining the Information and the undersigned hereby releases them from liability for any damage whatsoever in that connection.

12. Each of the undersigned acknowledges and agrees that the Company will not consummate any Business Combination with any company with which the undersigned has had any discussions, formal or otherwise, prior to the consummation of the IPO, with respect to a Business Combination.

13. Each of the undersigned acknowledges and agrees that the Company will not consummate any Business Combination which involves a company which is affiliated with any of the undersigned unless the Company obtains an opinion from an independent investment banking firm that the business combination is fair to the Company’s stockholders from a financial perspective.

14. Each of the undersigned has full right and power, without violating any agreement to which he or it is bound (including, without limitation, any non-competition or non-solicitation agreement with any employer or former employer), to enter into this Letter Agreement and to serve as an officer of the Company or as a director on the board of directors of the Company, as applicable, and hereby consents to being named in the Prospectus as an officer and/or as a director of the Company, as applicable.

17. No party may assign either this Letter Agreement or any of his or its rights, interests, or obligations hereunder without the prior written consent of the other party.

The parities hereto (i) agree that any action, proceeding, claim or dispute arising out of, or relating in any way to, this Letter Agreement shall be brought and enforced in the courts of New York, in the State of New York, and irrevocably submits to such jurisdiction and venue, which jurisdiction and venue shall be exclusive and (ii) waives any objection to such exclusive jurisdiction and venue or that such courts represent an inconvenient forum.
