2/7

Each Party, on its own behalf and on behalf of its Related Parties, covenants that neither such Party nor any of its Related Parties will (and that such Party will cause its Related Parties not to) sue, or bring, assert or otherwise pursue any allegation, claim, proceeding or other action against any of the entities that they are releasing hereunder on the basis of any matters released pursuant to this Agreement, regardless of whether such allegation, claim, proceeding or other action is enforceable under, or not prohibited by, applicable law or otherwise.

4. The Parties each expressly assume the risk that by entering into this Agreement and the releases contained herein, each will forever waive claims, causes of action, and damages that may exist before the Effective Date, but which it does not know of, or suspect to exist, and which, if known, would have materially affected the Party’s decision to enter into this Agreement.

5. Each Party, on its own behalf and on behalf of its Related Parties, hereby expressly agrees that the release contemplated by this Agreement extends to any and all rights granted under Section 1542 of the California Civil Code (“Section 1542”) and any analogous state law or federal law or regulation, and all such rights are hereby expressly, irrevocably and unconditionally waived. Section 1542 reads as follows:

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR OR RELEASING PARTY DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE AND THAT, IF KNOWN BY HIM OR HER, WOULD HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR OR RELEASED PARTY.”

6. Each Party, on its own behalf and on behalf of its Related Parties, understands that Section 1542, or a comparable statute, rule, regulation or order of another jurisdiction, gives such person the right not to release existing claims of which such person is not aware, unless such person voluntarily chooses to waive this right. Having been so apprised, each Party, on its own behalf and on behalf of its Related Parties, nevertheless hereby voluntarily elects to and does waive the rights described in Section 1542, or such other comparable statute, rule, regulation or order, and elects to assume all risks for claims that exist, existed or may hereafter exist in its favor, known or unknown, suspected or unsuspected, arising out of or related to claims or other matters purported to be released pursuant to this Agreement.

7. Each Party, on its own behalf and on behalf of its Related Parties, (a) acknowledges and agrees that the foregoing waiver set forth in Section 5 is an essential and material term of this Agreement and that, without such waiver, the other Parties would not have agreed to the terms of this Agreement, (b) hereby represents to the other Parties that it understands and acknowledges that it may hereafter discover facts, documents and legal theories concerning the entities being released hereunder or the subject matter hereof in addition to or different from those which it now believes to be true, (c) acknowledges and agrees no entity being released hereunder in any capacity shall have any duty to disclose or provide any such facts, documents or legal theories (whether material or immaterial, known or unknown, suspected or unsuspected, foreseen or unforeseen) to such Party solely by reason of the releases being provided by such Party and its Related Parties hereto, (d) each entity being released hereunder shall be deemed to have fully, finally and forever settled and released any and all claims, whether known or unknown, concealed, suspected or unsuspected, contingent or non-contingent, assertable directly or derivatively by class representative or individual, which now exist or heretofore have existed or will in the future exist to the extent such claims are actually released pursuant to this Agreement, (e) understands and hereby agrees that the releases set forth in this Agreement shall remain effective in all respects notwithstanding those additional or different facts and legal theories or the discovery of those additional or different facts or legal theories, and (f) hereby assumes the risk of any mistake of fact or applicable law with regard to any potential claim or with regard to any of the facts that are now unknown to it relating thereto.

8. The Parties agree that RPV or any of its Related Parties will not be responsible for providing tax reporting and withholding for payments made pursuant to this Agreement under applicable law. If RPV or any of its Related Parties becomes liable for the payment of taxes, assessments or other similar governmental charges, including, but not limited to, withholding taxes, and any interest, penalties, addition to taxes or other similar items thereon, relating to or in respect of any payment made by it pursuant this Agreement, RPV may satisfy such liability to the extent possible from amounts otherwise payable to the applicable payee pursuant to Section 2. To the extent that such amounts are withheld or deducted and timely paid over to or deposited with the relevant governmental authority, such deducted and withheld amounts shall be treated for all purposes of this Agreement as having been paid to the applicable payee in respect to which such deduction and withholding was made. Smartfin and Open Ocean shall, jointly and severally, indemnify and hold RPV and its Related Parties harmless from any liability or obligation on account of taxes, assessments or other similar governmental charges, and any interest, penalties, addition to taxes or other similar items thereon, that may be assessed or asserted against RPV or any of its Related Parties relating to or in respect of any amounts payable pursuant to this Agreement.

9. Each party will bear its own fees and costs related to the Released Claims and the preparation and negotiation of this Agreement.

10. This Agreement is binding upon and shall inure to the benefit of each Party, its Related Parties and their respective successors and assigns.

11. This Agreement shall be deemed to have been entered into and shall be construed and enforced in accordance with the internal laws of the State of Delaware as applied to contracts made and to be performed entirely within the State of Delaware without giving effect to any choice or conflict of law provisions that would result in the application of any law other than the law of the State of Delaware. The Parties (a) hereby irrevocably and unconditionally submit to the jurisdiction of the state courts of Delaware and to the jurisdiction of the United States District Court for the District of Delaware for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement, (b) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except in the state courts of Delaware and the United States District Court for the District of Delaware, and (c) hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court. THE PARTIES TO THIS AGREEMENT HEREBY WAIVE THEIR RIGHT TO A TRIAL BY JURY WITH RESPECT TO DISPUTES ARISING UNDER THIS AGREEMENT AND CONSENT TO A BENCH TRIAL WITH THE APPROPRIATE JUDGE ACTING AS THE FINDER OF FACT.

The provisions of this Agreement may be waived, altered, amended or repealed in whole or in part only upon the written consent of all Parties.

13. This Agreement may be executed in separate counterparts by the Parties, and each counterpart when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute but one and the same instrument.

14. Each of the Parties has been represented by counsel in the preparation of this Agreement.

15. This Agreement is made among financially sophisticated and knowledgeable parties and entered into by the Parties in reliance upon the economic and legal bargains contained herein and shall be interpreted and construed in a fair and impartial manner without regard to such factors as the Party who prepared (or caused the preparation of) such agreement or the relative bargaining power of the Parties.

Each Party represents and warrants that the person signing this Agreement in a representative capacity on its behalf has that Party’s authority to so sign and that it will be bound by the signatory’s execution of this Agreement.

17. If any provision of this Agreement is determined to be invalid or unenforceable, then (i) the remainder of this Agreement, or the application of such term, covenant or condition to the Parties or circumstances other than those as to which it is held invalid or unenforceable, shall not be affected thereby and each term, covenant or condition of this Agreement shall be valid and be enforced to the fullest extent permitted by law; and (ii) the Parties covenant and agree to renegotiate any such term, covenant or application thereof in good faith in order to provide a reasonably acceptable alternative to the term, covenant or condition of this Agreement or the application thereof that is invalid or unenforceable, it being the intent of the Parties that the basic purposes of this Agreement are to be effectuated.

No waiver of a breach or provision of this Agreement will be deemed effective, unless provided in writing by the allegedly waiving Party. A waiver by a Party of a breach or provision will not operate as a waiver of any other breach or provision, or of any subsequent or continuing breach.
