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 between ROI Acquisition Corp. II, a Delaware corporation (the “Company”), and Deutsche Bank Securities Inc., as representative of the several underwriters (the “Underwriters”), relating to an underwritten initial public offering (the “Public Offering”), of 12,500,000 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 (each, a “Warrant”). Each Warrant entitles the holder thereof to purchase one-half of one share of the Common Stock 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 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, GEH Capital, Inc. (the “Sponsor”) and the undersigned individuals, each of whom is a director or member of the Company’s management team (each, an “Insider” and collectively, the “Insiders”), hereby agrees with the Company as follows:

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

2. The Sponsor hereby agrees that in the event that the Company fails to consummate a Business Combination (as defined in the Underwriting Agreement) within 21 months from the closing of the Public Offering (or 24 months from the closing of the Public Offering if the Company has executed a letter of intent, agreement in principle or definitive agreement for an initial Business Combination within 21 months from the closing of the Public Offering but has not completed the initial Business Combination within such 21-month period), or such later period approved by the Company’s stockholders in accordance with the Company’s amended and restated certificate of incorporation, the Sponsor 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 Common

Stock 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 $50,000 of interest to pay dissolution expenses) less franchise and income taxes payable, divided by the number of then outstanding public shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (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 stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and other requirements of applicable law. The Sponsor agrees to not propose any amendment to the Company’s amended and restated certificate of incorporation 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 21 months from the closing of the Public Offering (or 24 months from the closing of the Public Offering if the Company has executed a letter of intent, agreement in principle or definitive agreement for a Business Combination within 21 months from the closing of the Public Offering but has not completed the Business Combination within such 21-month period).

The Sponsor acknowledges that it 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 Company with respect to the Founder Shares. The Sponsor hereby further waives, with respect to any shares of the Common Stock held by it, any redemption rights 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 Sponsor shall be entitled to redemption and liquidation rights with respect to any shares of the Common Stock (other than the Founder Shares) it holds if the Company fails to consummate a Business Combination within 21 months from the date of the closing of the Public Offering (or 24 months from the closing of the Public Offering if the Company has executed a letter of intent, agreement in principle or definitive agreement for a Business Combination within 21 months from the closing of the Public Offering but has not completed the Business Combination within such 21-month period).

3. During the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the Sponsor 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 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, shares of Common Stock, Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by 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 specified in clause (i) or (ii). In the event that the Company waives the foregoing restrictions, the Company shall issue a press release stating such waiver.

4. In the event of the liquidation of the Trust Account, the Sponsor, Joseph A. De Perio and George E. Hall jointly and severally (the “Indemnitors”) agree 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 (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 franchise and income taxes payable, 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 Indemnitors 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 Indemnitors 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 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 Indemnitors, the Indemnitors notify 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 an additional 1,875,000 shares of the Common Stock (as described in the Prospectus), the Sponsor agrees that it shall return to the Company for cancellation at no cost, a number of Founder Shares equal to 468,750 multiplied by a fraction, (i) the numerator of which is 1,875,000 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 1,875,000, provided, however, that in the event that the Sponsor transfers any of the Founder Shares prior to the exercise of the Over-allotment, if any, the percentage of Founder Shares to be returned by the Sponsor to the Company shall be reduced by the corresponding percentage of the Founder Shares transferred. The Sponsor further agrees that to the extent that (a) the size of the Public Offering is increased or decreased and (b) the Sponsor has either purchased or sold shares of 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 Public Offering, then (A) the references to 1,875,000 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 Public Offering and (B) the reference to 468,750 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 collectively return to the Company in order to hold an aggregate of 20.0% of the Company’s issued and outstanding shares after the Public Offering. In addition, a portion of the Founder Shares in an amount equal to 5.0% of the Company’s issued and outstanding shares immediately after the Public Offering (the “Founder Earnout Shares”), shall be returned to the Company by the Sponsor on the fifth anniversary of the completion of a Business Combination unless following such Business Combination the last sales price of the Company’s common stock equals or exceeds $13.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period or the Company completes a liquidation, merger, stock exchange or other similar transaction that results in all of its stockholders having the right to exchange their shares of common stock for consideration in cash, securities or other property which equals or exceeds $13.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like);

6. (a) The Sponsor hereby agrees not to participate in the formation of, or become an officer or director of, any other blank check company until the Company has entered into a definitive agreement with respect to a Business Combination or the Company has failed to complete a Business Combination within 24 months after the closing of the Public Offering.

    (b) The Sponsor and each Insider hereby agrees and acknowledges that: (i) each of the Underwriters and the Company would be irreparably injured in the event of a breach by such Sponsor or Insider of his, her or its obligations under paragraph 6(a), (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. (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 last sales price of the common stock (x) equals or exceeds $12.50 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period after a Business Combination, after which Transfers of fifty percent (50%) of the Founder Shares will be permitted, or (y) equals or exceeds $15.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period after our initial business combination, after which Transfers of the remaining fifty percent (50%) of the Founder Shares will be permitted and (B) the date following the completion of a Business Combination on which the Company completes a liquidation, merger, stock exchange or other similar transaction that results in all of the Company’s stockholders having the right to exchange their shares of Common Stock 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 Common Stock 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 shares of Common Stock underlying the Private Placement Warrants are permitted to (a) to the Company’s officers or directors, any affiliates or family members of any of the Company’s officers or directors or any affiliates of the Sponsor, or any affiliates of the Sponsor; (b) in the case of an individual, by a gift to a member of one of the members 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) in the event of the Company’s liquidation prior to the completion of a Business Combination; or (g) in the event of completion of a 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 subsequent to the completion of a Business Combination; provided, however, that in the case of clauses (a) through (e), these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions.
