Re:   Initial Public Offering

Gentlemen:

This letter (this “Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) entered into by and among Double Eagle Acquisition Corp., a Cayman Islands exempted company (the “Company”), Deutsche Bank Securities Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated, as representatives (the “Representatives”) of the several underwriters (the “Underwriters”), relating to an underwritten initial public offering (the “Public Offering”), of 46,000,000 of the Company’s units (including up to 6,000,000 Units that may be purchased to cover over-allotments, if any, the “Units”), each comprised of one of the Company’s Class A ordinary shares, par value $0.0001 per share (the “Ordinary Shares”), and one warrant (each, a “Warrant”). Each Warrant entitles the holder thereof to purchase one-half of one Ordinary Share at a price of $5.75 per half share, subject to adjustment. The Units shall be sold in the Public Offering pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the United States Securities and Exchange Commission (the “Commission”) and the Company shall apply to have the Units listed on the Nasdaq Capital Market. Certain capitalized terms used herein are defined in paragraph 11 hereof.

In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Double Eagle Acquisition LLC (the “Sponsor”) and each of the members of Double Eagle Acquisition LLC (each, a “Member” and collectively, the “Members”) hereby agree with the Company as follows:

1.  The Sponsor agrees that if the Company seeks shareholder approval of a proposed initial Business Combination, then in connection with such proposed Business Combination, it or he, as applicable, shall vote all Founder Shares and any shares acquired by it or him, as applicable, in the Public Offering or the secondary public market in favor of such proposed initial Business Combination and not redeem any Ordinary Shares owned by it or him, as applicable, in connection with such shareholder approval.

2.  The Sponsor and Members hereby agree that in the event that the Company fails to consummate its initial Business Combination within 24 months from the closing of the Public Offering (or such later period approved by the Company’s shareholders in accordance with the Company’s amended and restated memorandum and articles of association), the Sponsor and each Member 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 but not more than 10 business days thereafter, redeem 100% of the Ordinary Shares sold as part of the Units in the Public Offering (the “Offering Shares”), at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (less up to $100,000 of interest to pay dissolution expenses) less income taxes payable, divided by the number of then outstanding public shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and other requirements of applicable law. The Sponsor and the Members agree not to propose any amendment to the Company’s amended and restated memorandum and articles of association that would affect the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within 24 months from the closing of the Public Offering unless the Company provides its public shareholders with the opportunity to redeem their Ordinary Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest, less income taxes payable, divided by the number of then outstanding public shares.

Each of the Members and the Sponsor acknowledges that they have 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 Company with respect to the Founder Shares. The Sponsor and each of the Members hereby further waive, with respect to any Ordinary Shares held by them, any redemption rights they may have in connection with the consummation of a Business Combination, including, without limitation, any such rights available in the context of a shareholder vote to approve such Business Combination or in the context of a tender offer made by the Company to purchase Ordinary Shares (although the Sponsor and the Members shall be entitled to redemption and liquidation rights with respect to any Ordinary Shares (other than the Founder Shares) they hold if the Company fails to consummate a Business Combination within 24 months from the date of the closing of the Public Offering).

3.  During the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the undersigned shall not, without the prior written consent of the Representatives (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, Ordinary Shares, Warrants or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares owned by him, her or it, (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, Ordinary Shares, Warrants or any securities convertible into, or exercisable, or exchangeable for, Ordinary Shares owned by him, her or it, 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, including the filing of a registration statement, specified in clause (i) or (ii). Each of the Members and the Sponsor acknowledges and agrees that, prior to the effective date of any release or waiver, of the restrictions set forth in this paragraph 3 or paragraph 6 below, the Company shall announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if the release or waiver is effected solely to permit a transfer not for consideration and the transferee has agreed in writing to be bound by the same terms described in this Letter Agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

4.  In the event of the liquidation of the Trust Account, Jeff Sagansky (the “Indemnitor”) 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 (a “Target”); provided, however, that such indemnification of the Company by the Indemnitor 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 the lesser of (i) $10.00 per share of the Offering Shares and (ii) the actual amount per share of the Offering Shares held in the Trust Account as of the date of the liquidation of the Trust Account, in each case less income taxes payable, and except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account (whether or not such agreement is enforceable) and 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. In the event that any such executed waiver is deemed to be unenforceable against such third party, the Indemnitor shall not be responsible for any liability as a result of any such third party claims. The Indemnitor 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 Indemnitor, the Indemnitor notifies the Company in writing that it shall undertake such defense.

5.  To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 6,000,000 Ordinary Shares within 45 days from the date of the Prospectus (as further described in the Prospectus), the Sponsor agrees that it shall automatically surrender to the Company for no consideration, on a pro rata basis in accordance with the percentage of Founder Shares held by it, for cancellation at no cost, an aggregate number of Founder Shares equal to 750,000 multiplied by a fraction, (i) the numerator of which is 6,000,000 minus the number of Ordinary Shares purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 6,000,000. The surrender for no consideration will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters so that the pre-offering shareholders will own, on an as-converted basis, an aggregate of 20.0% of the Company’s issued and outstanding Capital Shares after the Public Offering. The Sponsor further agrees that to the extent that the size of the Public Offering is increased or decreased, the Company will purchase or sell Ordinary Shares or effect a share repurchase or share capitalization, as applicable, immediately prior to the consummation of the Public Offering in such amount as to maintain the ownership of the pre-offering shareholders prior to the Public Offering, on an as-converted basis, at 20.0% of its issued and outstanding Capital Shares upon the consummation of the Public Offering. In connection with such increase or decrease in the size of the Public Offering, then (A) the references to 6,000,000 in the numerator and denominator of the formula in the first sentence of this paragraph shall be changed to a number equal to 15% of the number of Ordinary Shares included in the Units issued in the Public Offering and (B) the reference to 750,000 in the formula set forth in the first sentence of this paragraph shall be adjusted to such number of Founder Shares that the Sponsor would have to collectively return to the Company in order to hold, on an as-converted basis, an aggregate of 10.0% of the Company’s issued and outstanding Capital Shares after the Public Offering.

6.  (a) The Sponsor agrees that it shall not Transfer any Founder Shares until the earlier of (A) one year after the completion of a Business Combination or earlier if, subsequent to a Business Combination, the closing price of the Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after a Business Combination, and (B) the date following the completion of a Business Combination on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property (the “Founder Shares Lock-up Period”).

(b) The Sponsor agrees that it shall not effectuate any Transfer of Private Placement Warrants or Ordinary Shares underlying such warrants, until 30 days after the completion of a Business Combination.

(c) Notwithstanding the provisions set forth in paragraphs 6(a) and (b), Transfers of the Founder Shares, Private Placement Warrants and Ordinary Shares underlying the Private Placement Warrants are permitted (a) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors, any members of the Sponsor or their affiliates, or any affiliates of the Sponsor (b) in the case of an individual, by gift to a member of the individual’s immediate family or to a trust, the beneficiary of which is a member of one of the individual’s immediate family, an affiliate of such person or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers made in connection with the consummation of a Business Combination at prices no greater than the price at which the shares were originally purchased; (f) by virtue of the Sponsor’s limited liability company agreement upon dissolution of the Sponsor; (g) in the event of the Company’s liquidation prior to the completion of a Business Combination; or (h) in the event of completion of a liquidation, merger, share exchange or other similar transaction which results in all of the Company’s shareholders having the right to exchange their Ordinary Shares for cash, securities or other property subsequent to the completion of a Business Combination; provided, however, that in the case of clauses (a) through (f) these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions.

7.  The Sponsor and each of the Members hereby agree and acknowledge that (i) each of the Underwriters and the Company would be irreparably injured in the event of a breach by the Sponsor or such Member of its or his obligations, as applicable, under paragraphs 1, 2, 3, 4, 5, 6(a), 6(b) and 9, (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.

8.  Each Member’s biographical information furnished to the Company (including any such information included in the Prospectus) is true and accurate in all respects and does not omit any material information with respect to such Member’s background. The Member’s questionnaire furnished to the Company is true and accurate in all respects. Each Member represents and warrants that: such Member 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; such Member 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 such Member is not currently a defendant in any such criminal proceeding; and neither such Member nor the Sponsor has ever 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.

9.  Except as disclosed in the Prospectus, neither the Sponsor, nor any Member, nor any affiliate of the Sponsor or any Founder, nor any director or officer of the Company, shall receive from the Company 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, none of which will be made from the proceeds of the Public Offering held in the Trust Account prior to the completion of a Business Combination: repayment of a loan of up to $200,000 made to the Company by the Sponsor, pursuant to a Promissory Note dated July 1, 2015; reimbursement for office space, secretarial and administrative services provided to members of the Company’s management team by an affiliate of the Sponsor, in an amount not to exceed $15,000 per month; reimbursement for any reasonable out-of-pocket expenses related to identifying, investigating and consummating a Business Combination; and 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 certain of the Company’s officers and directors to finance transaction costs in connection with an intended Business Combination, provided, that, if the Company does not consummate a 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. Up to $1,500,000 of such loans will be convertible into warrants of the post Business Combination entity at a price of $0.50 per warrant at the option of the lender. Such warrants would be identical to the Private Placement Warrants.

10.  The Sponsor and each Member have 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, as applicable, to serve as a director on the board of directors of the Company and each Member hereby consents to being named in the Prospectus as an officer and/or director of the Company, as applicable.

11.  As used herein, (i) “Business Combination” shall mean a merger, capital share exchange, asset acquisition, share purchase, reorganization or similar business combination, involving the Company and one or more businesses; (ii) “Capital Shares” shall mean, collectively, the Ordinary Shares and the Founder Shares; (iii) “Founder Shares” shall mean the 11,500,000 Class B ordinary shares of the Company, par value $0.0001 per share, outstanding prior to the consummation of the Public Offering (or 10,000,000 Class B ordinary shares if the over-allotment is not exercised by the Underwriters); (iv) “Private Placement Warrants ” shall mean the Warrants to purchase Ordinary Shares that will be acquired by the Sponsor and Harry E. Sloan for an aggregate purchase price of $8.0 million, or $0.50 per Warrant, in a private placement that shall occur simultaneously with the consummation of the Public Offering; (v) “Public Shareholders” shall mean the holders of securities issued in the Public Offering; (vi) “Trust Account” shall mean the trust fund into which a portion of the net proceeds of the Public Offering shall be deposited; and (vii) “Transfer” shall mean the (a) sale of, offer to sell, contract or agreement to sell, hypothecate, pledge, grant of any option to purchase or otherwise dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position or liquidation with respect to or decrease of 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 security, (b) entry into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any security, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (c) public announcement of any intention to effect any transaction specified in clause (a) or (b).

12.  This Letter Agreement constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and supersedes all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent they relate in any way to the subject matter hereof or the transactions contemplated hereby. This Letter Agreement may not be changed, amended, modified or waived (other than to correct a typographical error) as to any particular provision, except by a written instrument executed by all parties hereto.

13.  No party hereto may assign either this Letter Agreement or any of its rights, interests, or obligations hereunder without the prior written consent of the other party. Any purported assignment in violation of this paragraph shall be void and ineffectual and shall not operate to transfer or assign any interest or title to the purported assignee. This Letter Agreement shall be binding on the Sponsor, each of the Members and each of their respective successors, heirs, personal representatives and assigns.

14.  This Letter Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The parties hereto (i) all 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 City, in the State of New York, and irrevocably submit to such jurisdiction and venue, which jurisdiction and venue shall be exclusive and (ii) waive any objection to such exclusive jurisdiction and venue or that such courts represent an inconvenient forum.

15.  Any notice, consent or request to be given in connection with any of the terms or provisions of this Letter Agreement shall be in writing and shall be sent by express mail or similar private courier service, by certified mail (return receipt requested), by hand delivery or facsimile transmission.

16.  This Letter Agreement shall terminate on the earlier of (i) the expiration of the Founder Shares Lock-up Period and (ii) the liquidation of the Company; provided, however, that this Letter Agreement shall earlier terminate in the event that the Public Offering is not consummated and closed by November 30, 2015, provided further that paragraph 4 of this Letter Agreement shall survive such liquidation.
