Buyer shall submit to Seller not less than thirty (30) Business Days prior to the due date for filing such Buyer Returns for review and comment by Seller, and Buyer shall take into account any reasonable changes to such Buyer Returns which are delivered to Buyer in writing within fifteen (15) Business Days prior to the due date for filing such Buyer Returns. The Seller agrees to pay to Buyer within ten (10) Business Days after the date on which Taxes are paid with respect to such periods an amount equal to the portion of such Taxes, if any, that relate to the portion of such Tax period ending on the Closing Date as determined pursuant to Section 5.5(c). With respect to the Buyer Returns described in this Section 5.5(b)(iii), the Buyer shall provide the Seller with a copy of such filed Buyer Returns.
(c)Allocation of Taxes. In the case of a taxable period that includes, but does not end on, the Closing Date (a “Straddle Period”), (a) Taxes imposed on a periodic basis (such as real, personal and intangible property taxes) for the Pre-Closing Tax Period shall be equal to the amount of such Taxes for the entire Straddle Period multiplied by a fraction, the numerator of which is the number of days during the Straddle Period that are in the Pre-Closing Tax Period and the denominator of which is the number of days in the Straddle Period; and (b) Taxes (other than Taxes described in clause (a)) for any Pre-Closing Tax Period shall be computed as if such taxable period ended as of the close of business on the Closing Date.
(d)Withholding. Notwithstanding anything in this Agreement to the contrary, Buyer and its Affiliates shall be entitled to deduct and withhold from any amount payable pursuant to this Agreement (including the Royalty Payments) such amounts as Buyer believes in good faith are required to be deducted and withheld with respect to the making of such payment under any provision of federal, state

26


or local (in each case, whether domestic or foreign) Tax Law and pay such amounts over to the appropriate Taxing Authority. The Buyer shall use commercially reasonable efforts to notify Seller reasonably in advance of the date that the applicable payment is to be made to provide such Seller with an opportunity to provide any form or documentation or take such other steps to avoid such withholding. To the extent that amounts are so deducted and withheld and paid over to the appropriate Taxing Authority, such amounts shall be treated for all purposes of this Agreement as having been paid to the party in respect of which such deduction and withholding was made.
(e)Cooperation and Exchange of Information. Each of Seller and Buyer shall, and shall cause their respective Affiliates to, (i) provide the other with such assistance as may reasonably be requested by the other Party in connection with the preparation of any Tax Return, audit or other examination by any Taxing Authority or Action relating to liability for Taxes in connection with the Purchased Assets, (ii) retain and provide the other with any records or other information that may be relevant to such Tax Return, audit or examination, Action or determination and (iii) provide the other with any final determination of any such audit or examination, Action or determination that affects any amount required to be shown on any Tax Return of the other for any period.
(f)Termination of Existing Tax Sharing Agreements. The Seller shall cause all Tax sharing arrangements other than any such arrangements entered into in the ordinary course of business the primary purpose of which is not Tax (whether written or not) with respect to or involving Elusys to be terminated as of the Closing Date and, after the Closing Date, Elusys shall not be bound thereby or have any Liability thereunder.
(g)Tax Indemnification.
(i)Survival. Notwithstanding anything in this Agreement to the contrary, the provisions of this Section 5.5 shall survive for the full period of all applicable statutes of limitations (giving effect to any waiver, mitigation or extension thereof) plus 60 days.
(ii)Indemnification. Seller shall indemnify Buyer and its Affiliates (including Elusys), and each of their respective officers, directors, employees, agents, and Representatives (each a “Buyer Indemnified Party”) against, and shall hold any Buyer Indemnified Parties harmless from and against, any and all Losses incurred or sustained by, or imposed upon, a Buyer Indemnified Party based upon, arising out of, with respect to or by reason of any Excluded Taxes, provided, however, that Seller shall not have any obligation to indemnify Buyer Indemnified Parties for Taxes to the extent such Taxes (x) are due to the unavailability in any Tax periods (or portions thereof) beginning after the Closing Date of any net operating losses,

27


credits or other Tax attributes (such as capital loss carry forwards, foreign tax credit carry forwards, asset bases, research and development credits, and depreciation periods) from a Tax period (or portion thereof) ending on or before the Closing Date, (y) result from any transactions or actions outside the ordinary course of business taken by the Buyer or any of its Affiliates on the Closing Date after the Closing that are not contemplated by this Agreement (it being understood that any actions taken pursuant to Section 5.8 are expressly contemplated by this Agreement), or (z) would not have been imposed but for a breach by Buyer or any of its Affiliates of the covenant contained in Section 5.5(i).
(h)Tax Refunds. The Seller shall be entitled to receive any refunds of the Taxes with respect to the Purchased Assets (including, any Taxes of Elusys) or credits received in lieu thereof (including, for the avoidance of doubt, any such refunds that are available to be claimed and for which an election is made to apply such refunds to estimated or other Taxes) plus any interest received with respect thereto from the applicable Tax Authorities for any Pre-Closing Tax Period but only to extent such Taxes were paid by the Seller or by or on behalf of Elusys prior to the Closing Date (any such refund, a “Pre-Closing Refund”). Notwithstanding the foregoing, Pre-Closing Refunds shall not include, and Buyer shall not be required to pay any amounts to Seller in respect thereof, any refunds or credits of Taxes to the extent attributable to any carryback of any Tax asset or attribute that originates in a taxable period (or portion thereof) ending after the Closing Date to a Pre-Closing Tax Period. Any refunds or credits of Taxes for any Straddle Period shall be apportioned between Seller and Buyer in the same manner as the liability for such Taxes is apportioned pursuant to Section 5.5(c). To the extent permitted by Law, any Pre-Closing Refund shall be claimed in cash rather than as a credit against future Tax Liabilities for a Tax period beginning after the Closing Date. Within thirty (30) Business Days, after receipt of any Pre-Closing Refund by the Buyer or any of its Affiliates (or, in the case of a credit obtained in lieu of such refund, no later than thirty (30) Business Days following the filing of the income Tax Return on which such credit is available to be used to offset Tax otherwise payable), the Buyer shall pay over to the Seller the amount of such Pre-Closing Refund, net of the amount of any Taxes imposed on Buyer or any of its Affiliates thereof in connection with the receipt or realization of such Pre-Closing Refund and any reasonable out-of-pocket expenses incurred by the Buyer or any of its Affiliates in obtaining such Pre-Closing Refund (including any income Taxes imposed thereon).
(i)Post-Closing Tax Covenant. Except as required by applicable Law, without the prior written consent of Seller (not to be unreasonably withheld, conditioned or delayed), Buyer shall not nor shall it permit any of its Affiliates to, with respect to the Purchased Assets or Elusys, (i) take any action on the Closing Date after the Closing other than in the ordinary course of business or as otherwise

28


contemplated by this Agreement, (ii) make any retroactive Tax election effective for any Pre-Closing Tax Period except as contemplated by Section 5.8, (iii) amend, file or re-file any Tax Return for any Pre-Closing Tax Period, except as contemplated by ‎Section 5.5(b)(iii), or (iv) waive or extend any statute of limitations for the assessment or collection of any Excluded Tax.
Section 5.6Public Announcements.
(a)Neither Buyer nor Seller, nor any Affiliate of either Party, shall issue any press release or otherwise make any public statement with respect to the provisions of this Agreement or the transactions contemplated by this Agreement without the prior written consent of the other Party. Notwithstanding anything to the contrary in this Agreement or any Related Document, either Party may issue a press release or make a public statement with respect to the transactions contemplated by this Agreement without the consent of the other Party as may be required by Law or the rules and regulations of any applicable securities exchange or market. If any Party proposes to issue a press release or make a public statement with respect to the transactions contemplated by this Agreement pursuant to this Section 5.6, it will provide copies of such press release or public statement to the other Party before such press release or public statement is made, unless this would be in breach of any Law or the rules and regulations of any applicable securities exchange or market, in which case a copy of such press release or public statement will be provided to the other Party as soon as reasonably practicable or in accordance with such Law, rules or regulations.
(b)From and after the Closing, except as required by Law or the rules and regulations of any applicable securities exchange or market, neither Seller nor any of its Affiliates shall issue any press release or otherwise make any public statement with respect to the Business without the consent of Buyer.
Section 5.7Expenses. Except as expressly set forth herein, each of Seller and Buyer shall bear its own costs and expenses incurred in connection with this Agreement and the transactions contemplated by this Agreement.
Section 5.8Tax Election.
(a)If requested by Buyer, Seller shall participate in making an election under Section 338(h)(10) of the Code and any corresponding election permitted under the applicable Laws of any local, state, or foreign jurisdiction (the “Election”) relative to transactions contemplated by this Agreement. Seller shall cooperate with Buyer to do all things reasonably necessary to make the Election, including but not limited to (i) joining with Buyer in making the Election, (ii) reasonably cooperating with Buyer and taking all actions necessary or appropriate to effect and preserve a timely Election, and (iii) participating in the timely filing of IRS Form 8023 and related or comparable forms for state, local, or foreign Law

29


purposes (collectively, the “Section 338(h)(10) Forms”). At Buyer’s request, Seller shall furnish to Buyer such information reasonably requested by Buyer in order to prepare the Section 338(h)(10) Forms, shall review and timely provide comments on such Section 338(h)(10) Forms as provided by Buyer to Seller, and shall, at Buyer’s request, execute such Section 338(h)(10) Forms prepared by Buyer (and agreed upon by the Parties) and deliver such Section 338(h)(10) Forms to Buyer for timely filing by Buyer with the applicable Governmental Authority.
(b)Promptly following the Closing, the Parties will jointly negotiate and calculate in good faith the amount of additional consideration, if any, which would compensate the Seller for the difference between (x) the after-Tax net proceeds that the Seller would receive if the Election is not made with respect to the sale of the Elusys Equity Interests and (y) the after-Tax net proceeds that the Seller would receive with the Election in effect with respect to the sale of the Elusys Equity Interests (the “Tax Adjustment”). The Parties shall endeavor in good faith to finalize the Tax Adjustment no later than 60 days before the deadline for filing the Section 338(h)(10) Election. If Buyer requests that Seller make the Election, the payment of the Tax Adjustment by Buyer to Seller shall be made no later than ten (10) Business Days after the final determination of the Tax Adjustment.
(c)Each Party hereto shall, and shall cause their Affiliates, to treat all payments of the Tax Adjustment as payments of additional Purchase Price for all income Tax purposes (including for purposes of computing the Tax Adjustment). Buyer and Seller shall file all Tax Returns consistently with the Election, the Section 338(h)(10) Forms and the Purchase Price Allocation (as appropriately adjusted) and shall not take any position on any Tax Returns or during the course of any audit or other action or proceeding that is inconsistent with such election, forms or schedule, unless required by a determination of an applicable Governmental Authority that is final.
Section 5.9Further Assurances.
(a)Seller shall, and shall cause its Affiliates to, at any time and from time to time after the Closing Date, upon the reasonable request of Buyer, do, execute, acknowledge, deliver and file, or cause to be done, executed, acknowledged, delivered or filed, all such further acts, deeds, transfers, conveyances, assignments or assurances as may be reasonably required for the transferring, conveying, assigning and assuring to Buyer, or for the aiding and assisting in the reducing to possession by Buyer of, any of the Purchased Assets, or for otherwise carrying out the purposes of this Agreement and the Related Documents.
(b)At a time mutually agreed by the parties hereto, Seller (with the assistance and cooperation of Buyer as reasonably requested by Seller) shall use reasonable best efforts to cause to be filed with the SEC a proxy statement (the “Proxy

30


Statement”) in connection with a special meeting of Seller’s stockholders to be held in order for Seller’s stockholders to approve and adopt the issuance of Seller’s common stock to Buyer as contemplated by the Note Investment. Seller shall use its reasonable best efforts to (i) cause the Proxy Statement when filed with the SEC to comply in all material respects with all legal requirements applicable thereto, (ii) respond as promptly as reasonably practicable to and resolve all comments received from the SEC concerning the Proxy Statement, and (iii) to take such other action related to the Proxy Statement as necessary or desirable in connection therewith, including, but not limited to, (x) establishing the record date for, duly calling, giving notice of, convening and holding the special meeting in accordance with applicable Law, (y) causing the Proxy Statement to be disseminated to the stockholders of Seller, and (x) soliciting proxies from the stockholders of Seller to vote in favor of the proposals set forth in the Proxy Statement. Seller shall, through the recommendation of its Board of Directors, recommend to its stockholders that such stockholders approve the proposals relating to the issuance of shares of Seller’s common stock to Buyer that is included by Seller in the Proxy Statement and shall include such unqualified recommendation of the Seller’s Board of Directors in the Proxy Statement. No filing of, or amendment or supplement to, the Proxy Statement will be made by Seller without the consent of Buyer, which consent shall not be unreasonably withheld, conditioned or delayed. Seller will advise Buyer promptly after it receives notice thereof of any request by the SEC for amendment of the Proxy Statement or requests by the SEC for additional information. Each of Seller and Buyer shall cooperate and mutually agree upon (such agreement not to be unreasonably withheld, conditioned or delayed), any response to comments of the SEC or its staff with respect to the Proxy Statement or any amendment to the Proxy Statement filed in response thereto.
(c)Subject to, and without altering the rights and obligations set forth in, Section 2.6, for a period of 18 months from and after the Closing Date, if either Buyer or Seller becomes aware that any of the Purchased Assets have not been transferred to Buyer or that any of the Excluded Assets have been transferred to Buyer, it shall promptly notify the other and the Parties hereto shall, as promptly as reasonably practicable, use commercially reasonable efforts to ensure such assets are transferred to the correct owner, with any necessary Third Party consents.

33


(a)Buyer shall make the Note Investment pursuant to the terms of the Convertible Note no later than forty (40) days following the date of this Agreement.
(b)From and after the Closing and for so long as any Royalty Payment may occur pursuant to the terms of this Agreement (the “Post-Closing Payment Period”), Buyer hereby agrees that during the Post-Closing Payment Period:
(i)Buyer shall, and shall cause Elusys, as applicable, to (A) use Commercially Reasonable Efforts to maintain, finance, operate and promote ANTHIM®;
(ii)Buyer shall, and shall cause Elusys to, at all times be operated to permit and facilitate the appropriate tracking and calculation of all Royalty Payments amounts that may become due and owing under this Agreement (collectively, the “Post-Closing Payment Amounts”), and Buyer will, and will cause Elusys to, at all times maintain appropriate and necessary Books and Records in accordance with GAAP to evidence and account for, and to pay over, the Post-Closing Payment Amounts and the calculation of such amounts pursuant to this Agreement; and
(iii)Buyer shall not, and shall cause Elusys not to, take any action, or fail to take any action, with the intention to reduce, or with the goal or purpose of reducing, any Post-Closing Payment Amount. Without limiting the foregoing, Buyer shall not take, and shall ensure that Elusys does not take any action or fail to take any action with the goal of (A) delaying the execution of a Contract for the sale or distribution of ANTHIM®, or otherwise delay the occurrence of a Royalty Payment, or (B) decreasing or delaying the Revenues Derived By Buyer, so as to minimize, reduce or eliminate any Post-Closing Payment Amount.
(c)Further, from and after the Closing and for so long as any Royalty Payments may occur pursuant to the terms of this Agreement:
(i)Buyer shall use and shall cause Elusys, as applicable, to use Commercially Reasonable Efforts to maintain, finance, operate and promote ANTHIM®;
(ii)Buyer shall not, and shall cause Elusys not to, directly or indirectly, sell, transfer or assign the Business, Elusys, or the equity of any entity or any material assets used or held for use in the operation of, or otherwise related to, the Business or Elusys (whether by merger, sale of stock, sale of assets or otherwise) unless (i) the purchaser, transferee or assignee of such assets expressly agrees to assume the Royalty Payments and (ii) Seller provides express, written consent to such sale, transfer, or assignment (such consent not to be unreasonably withheld); and

34


(iii)Buyer shall fulfill, and hereby agrees to be bound by, the terms and conditions set forth in the Elusys Merger Agreement with respect the maintenance and operation of the Business (as that term is defined in the Elusys Merger Agreement) (including without limitation Sections 5.2, 5.4, and 12.1 of the Elusys Merger Agreement) for the benefit of the Stockholders (as that term is defined in the Elusys Merger Agreement).
(d)Commencing from and after the first anniversary of the Closing Date, if Seller proposes to register any of its Common Stock under the Securities Act of 1933, as amended, in connection with the public offering of such securities solely for cash, Seller shall, at such time, promptly give Buyer notice of such registration. Buyer shall have the right to request that Seller include the Conversion Shares as part of any other registration of securities filed by Seller (other than in connection with a transaction contemplated by Rule 145(a) promulgated under the Securities Act or pursuant to Form S-8 or any equivalent form); provided, however, that if, solely in connection with any primary underwritten public offering for the account of Seller, the managing underwriter(s) thereof shall, in its or their reasonable discretion, impose a limitation on the number of shares of Common Stock which may be included in the registration statement because, in such underwriter(s)’ judgment, marketing or other factors dictate such limitation is necessary to facilitate public distribution, then Seller shall be obligated to include in such registration statement only such limited portion of the Conversion Shares with respect to which Buyer requested inclusion hereunder as the underwriter(s) shall reasonably permit. Upon the request of Buyer given within ten (10) days after such notice is given by Seller, Seller shall, subject to the provisions of this Agreement, use reasonable efforts to cause to be registered all of the Conversion Shares that Buyer has requested to be included in such registration. Seller shall not be required to include any Conversion Shares in any underwritten offering unless the Buyer accepts the terms of such underwriting as agreed between Seller and the underwriter(s) and executes any documents as may be reasonably requested by the underwriter(s).
(e)Seller shall bear all fees and expenses attendant to registering the Conversion Shares pursuant to Section 6.5(d) above, but Buyer shall pay any and all underwriting commissions and the expenses of any legal counsel selected by Buyer to represent it in connection with the sale of the Conversion Shares. In the event of such a proposed registration, Seller shall furnish Buyer with not less than thirty (30) days written notice prior to the proposed date of filing of such registration statement. Such notice to Buyer shall continue to be given for each registration statement filed by Seller until such time as all of the Conversion Shares have been sold by Buyer. Buyer shall exercise the “piggy-back” registration rights provided for herein by giving written notice within ten (10) days of the receipt of Seller’s notice of its intention to file a registration statement.

35


ARTICLE VII​
TERMINATION
Section 7.1Termination. This Agreement may be terminated at any time prior to the Closing:
(a)by the written consent of Buyer and Seller;
(b)by either Buyer or Seller, if:
(i)the Closing shall not have occurred on or before thirty-two (32) days following the date of this Agreement (the “Outside Date”); provided, however, that if the condition set forth in Section 6.1(d) hereof has not been satisfied on or before thirty-two (32) days following the date of this Agreement, the “Outside Date” shall be such later date; provided further, however, that the right to terminate this Agreement under this Section 7.1(b)(i) shall not be available to any Party whose failure to perform and comply with any covenant, agreement or obligation contained in this Agreement has been the primary cause of, or primarily resulted in, the failure of the Closing to occur on or before such date;
(ii)if any Legal Restraint having the effect of restraining, enjoining or otherwise preventing the consummation of the transactions contemplated by this Agreement shall be in effect and shall have become final and non-appealable; or
(iii)the other Party shall have breached or failed to perform any of its representations, warranties, covenants, agreements or obligations contained in this Agreement, and such breach or failure to perform (A) would give rise to the failure of a condition set forth in Section 6.2(a) or Section 6.2(b) or in Section 6.3(a) or Section 6.3(b), as applicable, and (B) cannot be cured by the Outside Date or, if capable of being cured by the Outside Date, has not been cured prior to the date that is 15 days from the date that such other Party receives written notice of such breach or failure to perform.
Section 7.2Notice of Termination. In the event of termination of this Agreement by either or both of Buyer and Seller pursuant to Section 7.1, written notice of such termination shall be given by the terminating Party to the other Party specifying the provision hereof pursuant to which such termination is made.
Section 7.3Effect of Termination. Notwithstanding anything to the contrary in this Agreement, in the event of termination of this Agreement by either or both of Buyer and Seller pursuant to Section 7.1, this Agreement shall terminate and become void and have no effect, and there shall be no liability or obligation on the part of any Party, other than the provisions of Section 5.4, this Section 7.3 and Article VIII, which shall survive any such termination; provided

36


that no such termination shall relieve any Party from liability for damages to another Party that accrue prior to such termination resulting from fraud or an intentional and knowing breach by a Party of any of its representations, warranties, covenants, agreements, obligations or undertakings set forth in this Agreement.
ARTICLE VIII​
GENERAL PROVISIONS
Section 8.1Survival; Waiver of Claims; Limitation of Damages; Indemnification.
(a)Survival. None of Seller’s representations, warranties, covenants, agreements and obligations in this Agreement shall survive beyond the Closing; provided that this Section 8.1 shall not limit any covenant, agreement or obligation contained in this Agreement that by its terms applies in whole or in part after the Closing, and the representations, warranties, covenants, agreements and obligations of Buyer in this Agreement shall survive the Closing until all of Buyer’s obligations under this Agreement have been fully satisfied and Seller shall be able to make a claim or commence an Action for any breaches by Buyer of such representations, warranties, covenants, agreements, and obligations.
(b)Waiver of Claims. IF THE CLOSING OCCURS, BUYER SHALL BE DEEMED TO HAVE WAIVED, AND HEREBY WAIVES, IN FULL ANY BREACH AND CLAIMS ARISING THEREFROM, OF ANY SELLER’S REPRESENTATIONS OR WARRANTIES, WHETHER OR NOT BUYER IS AWARE OF, OR BECOMES AWARE OF, SUCH BREACH BEFORE, AT OR AFTER THE CLOSING.
(c)Limitation of Liability. NOTWITHSTANDING ANY OTHER PROVISION IN THIS AGREEMENT, IF THE CLOSING OCCURS, IN NO EVENT SHALL SELLER’S AGGREGATE LIABILITY FOR LOSSES ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE TRANSACTION DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED HEREBY, WHETHER RELATING TO A BREACH OF A REPRESENTATION AND WARRANTY, COVENANT, AGREEMENT OR OBLIGATION IN THIS AGREEMENT AND WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAWS OR OTHERWISE, EXCEED ONE HUNDRED THOUSAND DOLLARS ($100,000.00) (“SELLER’S LIABILITY CAP”); PROVIDED, HOWEVER, THAT, SUCH LIMITATION ON LIABILITY SHALL NOT APPLY TO ANY SUCH LOSSES RESULTING FROM, ARISING OUT OF OR RELATING TO SECTION 5.5(g) (TAX INDEMNIFICATION) OR ANY FEES AND EXPENSES OWED TO ANY PERSON WHO HAS ACTED, DIRECTLY OR INDIRECTLY, AS A BROKER, FINDER OR FINANCIAL ADVISOR TO SELLERS IN CONNECTION WITH THE TRANSACTIONS (WHICH LOSSES SHALL BE LIMITED TO THE ACTUAL DOLLAR AMOUNT OF SUCH FEES AND EXPENSES). THE PARTIES AGREE THAT SELLER’S

37


LIABILITY CAP IS AN AMOUNT THAT IS REASONABLE IN LIGHT OF THE ANTICIPATED OR ACTUAL HARM CAUSED BY ANY SUCH BREACH CONTEMPLATED ABOVE, THE DIFFICULTIES OF PROOF OF LOSS ARISING FROM SUCH BREACH, AND THE INCONVENIENCE OR INFEASIBILITY OF OTHERWISE OBTAINING AN ADEQUATE REMEDY FOR SUCH BREACH.
(d)Limitation of Damages. NOTWITHSTANDING ANY OTHER PROVISION IN THIS AGREEMENT, NO PARTY SHALL BE LIABLE FOR SPECIAL, PUNITIVE, EXEMPLARY, INCIDENTAL, CONSEQUENTIAL OR INDIRECT DAMAGES (INCLUDING LOSS OF REVENUE, INCOME OR PROFITS BUT ONLY TO THE EXTENT THE SAME ARE NOT DIRECT DAMAGES), DIMINUTION OF VALUE OR LOSS OF BUSINESS REPUTATION OR OPPORTUNITY OF ANY OTHER PARTY OR ANY OF SUCH PARTY’S AFFILIATES, WHETHER BASED ON CONTRACT, TORT, STRICT LIABILITY, OTHER LAW OR OTHERWISE; PROVIDED, HOWEVER, THAT SUCH LIMITATIONS SHALL NOT LIMIT ANY PARTY’S RIGHT TO RECOVER CONTRACT DAMAGES IN CONNECTION WITH THE OTHER PARTY’S FAILURE TO CLOSE IN VIOLATION OF THIS AGREEMENT.
(e)Indemnification. Buyer shall indemnify, defend, and hold harmless Seller and its Affiliates and their respective partners managers, members, directors, officers, shareholders, Representatives, agents, employees, successors and assigns (collectively the “Seller Indemnified Parties”) from and against any and all Losses suffered, sustained or incurred by any Seller Indemnified Party to the extent based upon, relating to, with respect to, arising or resulting from or in connection with, or alleged to result from, arise out of or in connection with any breach, non-performance or non-fulfilment of any covenant, restriction or agreement made, or required to be performed, by Seller in the Elusys Merger Agreement for any alleged action or omission (i) undertaken in connection with this Agreement or the transactions contemplated hereby or (ii) otherwise occurring on and after the date of this Agreement.
Section 8.2Rules of Construction. The Parties agree that they have been represented by counsel during the negotiation and execution of this Agreement and have together drafted this Agreement and, therefore, waive the application of any Law, regulation, holding or rule of construction providing that ambiguities in an agreement or other document will be construed against the Party drafting such agreement or document.
Section 8.3Notices. All notices, requests, claims, demands and other communications hereunder shall be given (and shall be deemed to have been duly given upon receipt) by hand delivery, by prepaid overnight courier (providing written proof of delivery), by electronic transmission or by certified or registered mail (return receipt requested and first class postage

(a)All Actions arising out of or relating to this Agreement shall be heard and determined exclusively in the Court of Chancery of the State of Delaware and any state appellate court therefrom within the State of Delaware (or in the event, but only in the event, that the Court of Chancery of the State of Delaware does not have subject matter jurisdiction, the Superior Court of the State of Delaware (Complex Commercial Division) or the United States District Court for the District of Delaware and the appellate court(s) therefrom). The parties hereto hereby (a) irrevocably submit to the exclusive jurisdiction of the Court of Chancery of the State of Delaware and any state appellate court therefrom within the State of Delaware (or in the event, but only in the event, that if the Court of Chancery of the State of Delaware does not have subject matter jurisdiction, the

40


Superior Court of the State of Delaware (Complex Commercial Division) or the United States District Court for the District of Delaware and the appellate court(s) therefrom) for the purpose of any Action arising out of or relating to this Agreement or the transactions brought by any party hereto, (b) irrevocably waive, and agree not to assert by way of motion, defense or otherwise, in any such Action, 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 Action is brought in an inconvenient forum, that the venue of the Action is improper, or that this Agreement may not be enforced in or by the above-named courts, and (c) agree that such party will not bring any Action arising out of or relating to this Agreement in any court other than the Court of Chancery of the State of Delaware (or in the event, but only in the event, that if the Court of Chancery of the State of Delaware does not have subject matter jurisdiction, the Superior Court of the State of Delaware (Complex Commercial Division) or the United States District Court for the District of Delaware and the appellate court(s) therefrom). Process in any such Action may be served on any party anywhere in the world, whether within or without the jurisdiction of any such court.
