NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, intending to be legally bound, do hereby agree as follows:

1. Definitions. Capitalized terms used but not otherwise defined herein shall have the respective meanings ascribed to such terms in the Transaction Agreement. When used in this Agreement, the following terms in all of their tenses, cases and correlative forms shall have the meanings assigned to them in this Section 1 or elsewhere in this Agreement.

“Beneficially Own” has the meaning assigned to such term in Rule 13d-3 under the Exchange Act, and a Person’s beneficial ownership of securities shall be calculated in accordance with the provisions of such Rule (in each case, irrespective of whether or not such Rule is actually applicable in such circumstance), provided, however, that securities shall only be considered to be Beneficially Owned by a Company Stockholder for purposes of this Agreement to the extent that (i) the Investment Manager has sole discretionary management authority of such securities that includes the sole authority to vote and (ii) any such securities are not on loan pursuant to a securities lending program. For the avoidance of doubt, “Beneficially Own” shall also include record ownership of securities where such record ownership satisfies the conditions of the proviso to the immediately preceding sentence.

“Beneficial Owners” shall mean Persons who Beneficially Own the referenced securities.

“Expiration Time” shall mean the earliest to occur of (a) the Effective Time, (b) such date and time as the Transaction Agreement shall be terminated pursuant to Article 9 thereof, or (c) the termination of this Agreement by mutual written consent of the Parties.

“Permitted Transfer” shall mean, in each case, with respect to each Company Stockholder, so long as (a) such Transfer is in accordance with applicable Law and such Company Stockholder is, and at all times has been, in compliance with this Agreement and (b) (i) prior to such Company Stockholder delivering the written consent pursuant to Section 3.1(a) below, any Transfer of Subject Securities by the Company Stockholder to another Company Stockholder or to an Affiliate of such Company Stockholder, so long as such Affiliate, in connection with, and prior to, such Transfer, executes a joinder to this Agreement, in form and substance reasonably acceptable to Parent, pursuant to which such Affiliate agrees to become a party to this Agreement and be subject to the restrictions and obligations applicable to such Company Stockholder and otherwise become a party for all purposes of this Agreement or (ii) after such Company Stockholder has delivered the written consent pursuant to Section 3.1(a) below, any Transfer of Subject Securities by the Company Stockholder to another Person, so long as such Person, in connection with, and prior to, such Transfer, executes a joinder to this Agreement, in form and substance reasonably acceptable to Parent, pursuant to which such Person agrees to become a party to this Agreement and be subject to the restrictions and obligations applicable to such Company Stockholder and otherwise become a party for all purposes of this Agreement; provided that no such Transfer shall relieve the transferring

Company Stockholder from its obligations under this Agreement if less than all of such Company Stockholder’s Common Stock is transferred, other than with respect to the Company Common Stock transferred in accordance with the foregoing provision.

“Subject Securities” shall mean, collectively, shares of Company Common Stock and New Company Common Stock.

“Transfer” means (a) any direct or indirect offer, sale, lease, assignment, encumbrance, loan, pledge, grant of a security interest, hypothecation, disposition or other transfer (by operation of law or otherwise), either voluntary or involuntary, or entry into any contract, option or other arrangement or understanding with respect to any offer, sale, lease, assignment, encumbrance, loan, pledge, hypothecation, disposition or other transfer (by operation of law or otherwise), of any capital stock or interest in any capital stock (or any security convertible or exchangeable into such capital stock), including in each case through the Transfer of any Person or any interest in any Person or (b) in respect of any capital stock or interest in any capital stock, to enter into any swap or any other agreement, transaction or series of transactions that hedges or transfers, in whole or in part, directly or indirectly, the economic consequence of ownership of such capital stock or interest in capital stock, whether any such swap, agreement, transaction or series of transaction is to be settled by delivery of securities, in cash or otherwise. For purposes of this Agreement, “capital stock” shall include interests in a partnership or limited liability company.

2.1 Transfer and Encumbrance of Subject Securities. Other than a Permitted Transfer and so long as the Investment Manager remains the legal owner, beneficial owner and/or investment advisor or manager of or with power and/or authority to bind such Company Stockholder, from the date hereof until the Expiration Time, the Investment Advisor shall not (on behalf of any Company Stockholder), with respect to any Subject Securities Beneficially Owned by such Company Stockholder, (a) Transfer any such Subject Securities, or (b) deposit any such Subject Securities into a voting trust or enter into a voting agreement or arrangement with respect to such Subject Securities or grant any proxy (except as otherwise provided herein or to grant a revocable proxy to the Company’s proxy holders to vote or cause to be voted the Subject Securities in accordance with this Agreement) or power of attorney with respect thereto.

2.2 Injunction. Notwithstanding anything to the contrary in this Agreement, if at any time following the date hereof and prior to the Expiration Time a Governmental Entity of competent jurisdiction enters an order restraining, enjoining or otherwise prohibiting the Company Stockholders or their Affiliates from (a) consummating the transactions contemplated by the Transaction Agreement or (b) taking any action pursuant to Section 3 or Section 5, then so long as the Investment Manager remains the legal owner, beneficial owner and/or investment advisor or manager of or with power and/or authority to bind such Company Stockholder, (i) the obligations of the Investment Advisor (on behalf of the Company Stockholders) set forth in Section 3 and the irrevocable proxy and power of attorney in Section 5 shall be of no force and effect for so long as such order is in effect and, in the case of clause (b), solely to the extent such order restrains, enjoins or otherwise prohibits the Investment Advisor (on behalf of such Company Stockholder) from taking any such action, and (ii) the Investment Advisor (on behalf of each Company Stockholder) shall cause the Subject Securities to not be represented in person

or by proxy at any meeting at which a vote of such Company Stockholder on the Transactions is requested. Notwithstanding anything to the contrary in this Section 2.2, the restrictions set forth in Section 2.1 shall continue to apply with respect to the Subject Securities until the Expiration Time.

2.3 Additional Purchases; Adjustments. The Investment Manager agrees (on behalf of each Company Stockholder) that any shares of Common Stock for which such Company Stockholder acquires Beneficial Ownership after the execution of this Agreement and prior to the Expiration Time (the “New Company Common Stock”) shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted Company Common Stock, and the Investment Manager shall promptly notify Parent of the existence of any such New Company Common Stock. In the event of any stock split, stock dividend, merger, reorganization, recapitalization, reclassification, combination, exchange of shares or the like of the capital stock of the Company affecting the Subject Securities, the terms of this Agreement shall apply to the resulting securities.

2.4 Unpermitted Transfers; Involuntary Transfers. Any Transfer or attempted Transfer of any Subject Securities in violation of this Section 2 shall, to the fullest extent permitted by Law, be null and void ab initio. If any involuntary Transfer of any of such Company Stockholder’s Subject Securities shall occur, the transferee (which term, as used herein, shall include any and all transferees and subsequent transferees of the initial transferee) shall take and hold such Subject Securities subject to all of the restrictions, liabilities and rights under this Agreement, which shall continue in full force and effect until valid termination of this Agreement.

3.1 Approval. From and after the date hereof until the Expiration Time, the Investment Manager irrevocably and unconditionally agrees (on behalf of the Company Stockholders) that it shall:

(a) within two (2) Business Days after the Registration Statement becomes effective under the Securities Act (but, for the avoidance of doubt, not until such Registration Statement becomes effective and the definitive consent solicitation statement/prospectus contained therein is delivered to it), deliver (or cause to be delivered) a written consent pursuant to Section 228 of the Delaware General Corporation Law and Article Twelfth of the Sailfish Amended and Restated Certificate of Incorporation covering all of the Subject Securities approving and adopting the Transactions, the Transaction Agreement and any other matters necessary for consummation of the Transactions and the other transactions contemplated in the Transaction Agreement (each a “Transaction Proposal”);

(b) at every meeting of the stockholders of the Company called with respect to any of the following matters, and at every adjournment or postponement thereof, it shall and shall cause each applicable holder of record on any applicable record date to (including via proxy), vote the Subject Securities: in favor of (i) any Transaction Proposal, and (ii) if an adjournment or postponement is required by the Transaction Agreement or approved by the Board of Directors of the Company, any proposal to adjourn or postpone such meeting of stockholders of the Company to a later date if there are not sufficient votes to approve the Transactions; and

(c) at every meeting of the stockholders of the Company called with respect to any of the following matters, and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Company with respect to any of the following matters, it shall, and shall cause each applicable holder of record on any applicable record date to (including via proxy), vote the Subject Securities against (i) any action or agreement that would reasonably be expected to result in any condition to the consummation of the Transactions set forth in Article 8 of the Transaction Agreement not being fulfilled, (ii) any Competing Proposal, (iii) any action which could reasonably be expected to materially delay, materially postpone or materially adversely affect the consummation of the transactions contemplated by the Transaction Agreement, including the Transactions, or dilute, in any material respect, the benefit of the transactions contemplated thereby to Parent or to Parent’s members and (iv) any action which could reasonably be expected to result in a breach of any representation, warranty, covenant or agreement of the Company in the Transaction Agreement.

3.2 Change of Recommendation. Notwithstanding anything to the contrary in this Agreement, if at any time from and after the date hereof until the Expiration Time there occurs a Change of Recommendation pursuant to Section 7.05(e)(iii) or Section 7.05(e)(iv) of the Transaction Agreement (a “Change of Recommendation Event”), then the Investment Advisor’s obligation (on behalf of each Company Stockholder) to deliver a written consent in accordance with Section 3.1(a) and to vote its Subject Securities in accordance with Section 3.1(b), shall be limited to the number of shares of Subject Securities held by such Company Stockholder, rounded down to the nearest whole share, equal to the product of (a) such Company Stockholder’s Pro Rata Share multiplied by (b) the Covered Company Common Stock (such amount for each Company Stockholder, the “Covered Securities”); provided that all other obligations and restrictions contained in this Agreement, including those set forth in Section 3.1(c), shall continue to apply to all of such Company Stockholder’s Subject Securities; provided, further, however, that if a Change of Recommendation Event occurs, notwithstanding any other obligations hereunder, the Investment Advisor (on behalf of each Company Stockholder) shall be expressly permitted to deliver a written consent covering, or vote, its Subject Securities that are not Covered Securities in its sole discretion with respect to any Transaction Proposal. For purposes of this Agreement, (i) the “Covered Company Common Stock” shall mean the total number of shares of Subject Securities outstanding as of the record date of the applicable stockholder meeting or established by the Company with respect to any action by written consent, as applicable, multiplied by 0.35 and (ii) such Company Stockholder’s “Pro Rata Share” shall be 0.34.

3.3 Conditions to Vote and Approval. The Investment Advisor’s obligations (on behalf of the Company Stockholders) under Section 3.1 above shall be conditioned upon the Transaction Agreement and the Transactions contemplated thereby being in conformance in all material respects with the Transaction Agreement attached hereto as Exhibit A, including with respect to the Franklin/MacKay Debt Exchange, and the ownership percentage of New Sailfish Common Stock by the former Sailfish stockholders upon consummation of the Transactions being no less than 37%.

4. Rights Unaffected. Nothing contained herein shall limit the rights of a Company Stockholder (or any Affiliate of the Investment Advisor) who is also a MacKay Bondholder under the Sailfish Notes or constitute an amendment or waiver of any provision of the Sailfish Notes.

5. Irrevocable Proxy. By execution of this Agreement, the Investment Advisor (on behalf of each Company Stockholder) hereby appoints and constitutes Parent, until the Expiration Time (at which time this proxy shall automatically be revoked), with full power of substitution and resubstitution, as such Company Stockholder’s true and lawful attorney-in-fact and proxy (which proxy is irrevocable and which appointment is coupled with an interest, including for purposes of Section 212 of the Delaware General Corporation Law), to the fullest extent of such Company Stockholder’s rights with respect to the Subject Securities Beneficially Owned by such Company Stockholder, to vote (or exercise a written consent with respect to) such Subject Securities solely with respect to the matters set forth in Section 3 hereof and each Company Stockholder shall retain the authority to vote its Subject Securities on all other matters; provided, however, that the foregoing shall only be effective if the Investment Advisor (on behalf of such Company Stockholder) fails to be counted as present, to consent or to vote such Company Stockholder’s Subject Securities, as applicable, in accordance with this Agreement; provided, further, however, that if at any time from and after the date hereof until the Expiration Time there occurs a Change of Recommendation Event, then the irrevocable proxy contemplated by this Section 5 shall terminate and cease to be effective with respect to all Subject Securities other than the Covered Securities.

6. Representations and Warranties of the Investment Manager. The Investment Manager hereby represents and warrants to Parent as follows:

The Parties agree that a final judgment in any such suit, action or proceeding shall be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner provided by Law.

Prior to the termination of this Agreement pursuant to Section 7, it is accordingly agreed that the Parties shall be entitled to seek an injunction or injunctions, or any other appropriate form of specific performance or equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of competent jurisdiction, in each case in accordance with this Section 12.7, this being in addition to any other remedy to which they are entitled under the terms of this Agreement at law or in equity.
