The Escrow Account shall be held by the Escrow Agent and released by the Escrow Agent to the Buyer or the Seller Representative, as applicable, in accordance with the terms of this Agreement and the Escrow Agreement.

(b) Any Escrow Shares distributed pursuant to the Escrow Agreement for the benefit of the Sellers shall be distributed in accordance with the Escrow Agreement. A portion of such distributed amount equal to the Pro Rata Share that is represented by each Share shall be delivered by the Escrow Agent to the Seller Representative pursuant to the terms of the Escrow Agreement for distribution to the holder of such Share.

1.5 Exchange Procedures. The procedures for the purchase and sale of the Shares in connection with the transactions contemplated by this Agreement are as follows:

(a) Procedures. At or prior to the Closing, each Seller shall deliver, or the Company shall deliver on a Seller’s behalf, to the Buyer the Certificates evidencing the Shares owned by such Seller duly endorsed in blank or with stock powers duly executed by such Seller. The transfer of the Shares by the Sellers to the Buyer shall be deemed to occur as of the close of business on the Closing Date. Upon proper delivery of the Certificates to the Buyer, each Seller shall be entitled to receive in exchange therefor the applicable portion of the Aggregate Closing Consideration in respect of the Shares represented by such Certificate, as reflected on the Closing Date Allocation Schedule attached to the Closing Payment Certificate. If payment in respect of any Certificate is to be made to a Person other than the Person in whose name such Certificate is registered, it shall be a condition of payment that the Certificate so delivered shall be transferable and be properly endorsed or shall otherwise be in proper form for transfer, that the signatures on such Certificate or any related stock power shall be properly guaranteed and that the Person requesting such payment shall have established to the satisfaction of Buyer that any transfer and other Taxes required by reason of such payment to a Person other than the registered holder of such Certificate have been paid or are not applicable. Until delivered as contemplated by this Section 1.5(a), each Certificate shall be deemed at all times after the Closing to represent only the right to receive upon such delivery the applicable portion of the Aggregate Closing Consideration and the applicable portion of any Escrow Shares that become payable pursuant to this Agreement. Sellers shall not be entitled to receive any portion of the Aggregate Consideration to which they would otherwise be entitled until such Certificates are properly delivered.

(b) No Liability. To the extent permitted by applicable Law, none of the Buyer or the Company shall be liable to any Seller for any amount delivered to a public official pursuant to any applicable abandoned property, escheat or similar Law. If any Certificates shall not have been exchanged prior to the fourth (4^th) anniversary of the Closing Date (or immediately prior to such earlier date on which the related consideration payable pursuant to this Article I would otherwise escheat to or become the property of any Governmental Entity), any such consideration in respect thereof shall, to the extent permitted by applicable Law, become the property of the Buyer, free and clear of all claims or interest of any Person previously entitled thereto.

- 4 -

(c) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact and a customary indemnification of the Company and the Buyer in a form reasonably satisfactory to the Buyer by the Person claiming such Certificate to be lost, stolen or destroyed, the Buyer shall pay in exchange for such lost, stolen or destroyed Certificate the portion of the Aggregate Consideration payable in respect thereof pursuant to this Agreement. The Buyer may, in its discretion and as a condition precedent to the payment thereof, require the owner of such lost, stolen or destroyed Certificate to give the Buyer a bond in such sum as it may reasonably direct as indemnity against any claim that may be made against the Buyer with respect to the Certificate alleged to have been lost, stolen or destroyed.

(d) No Fractional Shares. All payments hereunder in the form of shares of Buyer Common Stock, including the portion of the Aggregate Closing Consideration and any Escrow Shares, shall be made only in whole shares, and any fractional shares shall be rounded down to the nearest whole share.

(e) Affiliate Legends. Section 1.5(e) of the Company Disclosure Schedule sets forth a list of those Persons who are, in Company’s reasonable judgment, “affiliates” of Company within the meaning of Rule 145 promulgated under the Securities Act (“Rule 145 Affiliates”). The Buyer shall be entitled to place appropriate legends on the certificates evidencing any shares of Buyer Common Stock to be received by Rule 145 Affiliates of the Company in connection with the Closing reflecting the restrictions set forth in Rule 145 promulgated under the Securities Act and to issue appropriate stop transfer instructions to the transfer agent for Buyer Common Stock.

1.6 Seller Representative.

(a) By their execution of this Agreement and the transfer and delivery of their Certificates, and/or their acceptance of any consideration pursuant to this Agreement the Sellers hereby irrevocably (subject only to Section 1.6(d)) appoint the Seller Representative as the representative, attorney-in-fact and agent of the Sellers in connection with the transactions contemplated by this Agreement and the Escrow Agreement and in any litigation or arbitration involving this Agreement or the Escrow Agreement. In connection therewith, the Seller Representative is authorized to do or refrain from doing all further acts and things, and to execute all such documents as the Seller Representative shall deem necessary or appropriate, and shall have the power and authority to:

(iv) receive funds, make payments of funds, and give receipts for funds;

(v) do or refrain from doing, on behalf of the Sellers, any further act or deed that the Seller Representative deems necessary or appropriate in the Seller Representative’s discretion relating to the subject matter of this Agreement or the Escrow Agreement, in each case as fully and completely as the Sellers could do if personally present;

(vi) give and receive all notices required to be given or received by the Sellers under this Agreement or the Escrow Agreement;

(viii) agree to, negotiate, enter into settlements and compromises and/or comply with arbitration awards and court orders with respect to claims for indemnification made by the Buyer under Article V; and

(ix) receive service of process in connection with any claims under this Agreement and/or the Escrow Agreement.

(b) All decisions and actions of the Seller Representative on behalf of the Sellers shall be deemed to be facts ascertainable outside of this Agreement and shall be binding upon all Sellers, and no Seller shall have the right to object, dissent, protest or otherwise contest the same.

(c) The Seller Representative shall act for the Sellers on all of the matters set forth in this Agreement and the Escrow Agreement in the manner the Seller Representative believes to be in the best interest of the Sellers. The Seller Representative is authorized to act on behalf of the Sellers notwithstanding any dispute or disagreement among the Sellers. In taking any action as Seller Representative, the Seller Representative may rely conclusively, without any further inquiry or investigation, upon any certification or confirmation, oral or written, given by any Person whom the Seller Representative reasonably believes to be authorized thereunto. The Seller Representative may, in all questions arising hereunder, rely on the advice of counsel, and the Seller Representative shall not be liable to any Seller for anything done, omitted or suffered in good faith by the Seller Representative based on such advice. The Seller Representative undertakes to perform such duties and only such duties as are specifically set forth in this Agreement and no implied covenants or obligations shall be read into this Agreement against the Seller Representative. The Seller Representative shall not have any liability to any of the Sellers

- 6 -

for any act done or omitted hereunder as Seller Representative while acting in good faith. The Seller Representative shall be indemnified by the Sellers from and against any loss, liability or expense incurred in good faith on the part of the Seller Representative and arising out of or in connection with the acceptance or administration of the Seller Representative’s duties hereunder.

(d) In the event the Seller Representative becomes unable to perform the Seller Representative’s responsibilities hereunder or resigns from such position, the Sellers (acting by a written instrument signed by Sellers who held, as of immediately prior to the Closing, a majority (by voting power) of the then outstanding Company Shares) shall select another representative to fill the vacancy of the Seller Representative, and such substituted representative shall be deemed to be the Seller Representative for all purposes of this Agreement. The Seller Representative may be removed only upon delivery of written notice to the Buyer signed by Sellers who, as of immediately prior to the Closing, held a majority (by voting power) of the then outstanding Company Shares; provided that no such removal shall be effective until such time as a successor Seller Representative shall have been validly appointed hereunder. Any substituted representative shall provide the Buyer prompt written notice of any such representative, including his, her or its identity and address.

(e) For all purposes of this Agreement:

(i) the Buyer shall be entitled to rely conclusively on the instructions and decisions of the Seller Representative as to the settlement of any disputes or claims under this Agreement or the Escrow Agreement, or any other actions required or permitted to be taken by the Seller Representative hereunder, and no party hereunder or any Seller shall have any cause of action against the Buyer for any action taken by the Buyer in reliance upon the instructions or decisions of the Seller Representative;

(ii) the provisions of this Section 1.6 are independent and severable, are irrevocable (subject only to Section 1.6(d)) and coupled with an interest and shall be enforceable notwithstanding any rights or remedies that any Seller may have in connection with the transactions contemplated by this Agreement; and

(iii) the provisions of this Section 1.6 shall be binding upon the executors, heirs, legal representatives, personal representatives, successor trustees and successors of each Seller, and any references in this Agreement to a Seller shall mean and include the successors to the rights of each applicable Seller hereunder, whether pursuant to testamentary disposition, the Laws of descent and distribution or otherwise.

1.7 Company Equity Awards; Convertible Securities. Prior to the Closing Date, the board of directors of the Company shall adopt the necessary resolutions, and the Company shall take all other actions, necessary to cause each unexercised, unconverted or unsettled, as the case may be, Company Option, Company RSU and Convertible Security outstanding as of immediately prior to the Closing to be terminated and cancelled without payment of any consideration.

- 7 -

1.8 Allocation Schedules; Payments of Escrow Shares.

(a) The Closing Date Allocation Schedule sets forth a true, correct and complete summary of the allocation of the amounts payable to the Sellers pursuant to this Agreement. The Company has delivered to the Buyer, prior to the date hereof, the Closing Date Allocation Schedule (attached as an exhibit to the Closing Payment Certificate). The Buyer shall be entitled to rely conclusively on the Closing Date Allocation Schedule, and, as between the Sellers, on the one hand, and the Buyer, on the other hand, any amounts delivered by the Buyer to any Seller (or delivered by the Buyer for delivery) in accordance with the Closing Date Allocation Schedule shall be deemed for all purposes to have been delivered to the applicable Seller in full satisfaction of the obligations of the Buyer under this Article I.

(b) The portion of any Escrow Shares payable pursuant to this Agreement shall be paid by the Buyer to the Seller Representative for the benefit of the Sellers.

(d) Accounting.

(i) Buyer shall, and shall require the other Selling Parties to, keep full, clear and accurate records for a period that need not exceed three (3) years after the relevant Earn-Out Payment is owed pursuant to Section 1.9(b), in each case in sufficient detail to enable the calculation of the applicable Earn-Out Payments. Buyer shall, and shall require the other Selling Parties to, upon not less than sixty (60) calendar days’ prior written notice from the Seller Representative, permit all such books and records relating to such three (3) year period to be examined by an independent accounting firm that (A) is selected by the Seller Representative, (B) is reasonably acceptable to Buyer and, if applicable, such Selling Party and (C) enters into a customary confidentiality agreement with Buyer and, if applicable, such Selling Party, for the purpose of verifying the reports provided by Buyer under Section 1.9(b)(ii). Such audit shall not be performed more frequently than once per calendar year, shall not include an audit of any books and records that were previously audited pursuant to this Section 1.9(d) and shall be conducted under appropriate confidentiality provisions for the sole purpose of verifying the accuracy and completeness of the underlying data from which the Earn-Out Payments are calculated and the calculation of Earn-Out Payments.

- 9 -

(ii) In the event that such audit concludes that any Earn-Out Payment was underpaid or overpaid, the Seller Representative or the Buyer, respectively, shall be entitled to deliver a written notice thereof (a “Dispute Notice”), in which case the Seller Representative and the Buyer shall, for a period of not less than thirty (30) days after delivery of the Dispute Notice, attempt in good faith to resolve the items in dispute. In the event no agreement can be reached by the Seller Representative and the Buyer as to the calculation of the applicable Earn-Out Payment within thirty (30) days after delivery of a Dispute Notice, then each of the Buyer and the Seller Representative, on behalf of the Sellers, shall have the right to pursue applicable legal remedies.

(iii) Any examination or audit pursuant to Section 1.9(d)(i) or Section 1.9(d)(ii) shall be at the expense of the Seller Representative, except in the event that the Seller Representative and the Buyer agree, or it is finally determined pursuant to the dispute resolution procedures set forth in this Section 1.9(d), that there was an underpayment of the Earn-Out Payments of five percent (5%) or more over the period being audited, in which case the reasonable audit fees charged by the independent accounting firm for such examination shall be paid by Buyer. The amount of any underpayment in any Earn-Out Payment for any audited period shall be paid by Buyer to the Seller Representative (for distribution to the Sellers) within twenty (20) Business Days following the agreement by the Seller Representative and the Buyer to the amount of such underpayment, or the determination of such underpayment by such dispute resolution mechanism. The amount of any overpayment in any Earn-Out Payment for any audited period shall be paid to the Buyer by the Seller Representative within twenty (20) Business Days following the agreement by the Seller Representative and the Buyer to the amount of such overpayment, or the determination of such overpayment by such dispute resolution mechanism.

(e) Late Payments. All Contingent Payments that are not paid within the applicable time period set forth herein shall accrue interest at the rate of three percent (3%) above the then-applicable London Interbank Offered Rate as quoted in the Wall Street Journal, or, if lower, the highest rate permitted under applicable law.

(ii) During the applicable Earn-Out Period with respect to each Major Country, China or Canada, the Buyer shall, and shall cause the other members of the Buyer Rights Group to, use Commercially Reasonable Efforts to commercialize the Product in such Major Country, China or Canada, respectively.

- 10 -

(iii) During the Development Diligence Period, the Buyer shall keep the Seller Representative informed of its progress through the annual provision of a written report summarizing the progress of the development of the Product in countries throughout the world, provided within thirty (30) days after the end of each calendar year.

(iv) During the applicable Earn-Out Period in each Major Country, China or Canada, as applicable, the Buyer shall keep the Seller Representative informed of its progress through the annual provision of a written report summarizing the progress of the development and commercialization of the Product in each Major Country, China and Canada, respectively, provided within thirty (30) days after the end of each calendar year.

(v) If the Seller Representative believes that Buyer is not devoting Commercially Reasonable Efforts for the Product in any country in accordance with Section 1.9(f)(i) or Section 1.9(f)(ii), the Seller Representative will notify Buyer in writing detailing its specific concerns, and the Seller Representative and a representative of the Buyer with knowledge of the development or commercialization (as the case may be) of the Product will meet within twenty (20) Business Days of such written notice to discuss such concerns.

(g) Miscellaneous. The rights and obligations of each Seller under this Section 1.9, including the right to receive payments, (i) are purely contractual rights and not a security for purposes of any federal or state securities Laws, (ii) will not be represented by any form of certificate or instrument, (iii) do not give Sellers any dividend rights, voting rights, liquidation rights, preemptive rights or other rights common to holders of the Buyer’s equity securities and (iv) are not transferrable, assignable or redeemable; provided that a Seller may transfer its rights and obligations under this Section 1.9 to a Permitted Transferee.

The Non-controlling Party may participate in such defense at its own expense. The Controlling Party shall keep the Non-controlling Party advised of the status of such Third Party Action and the defense thereof and shall consider in good faith recommendations made by the Non-controlling Party with respect thereto. The Non-controlling Party shall furnish the Controlling Party with such information as it may have with respect to such Third Party Action (including copies of any summons, complaint or other pleading which may have been served on such party and any written claim, demand, invoice, billing or other document evidencing or asserting the same) and shall otherwise cooperate with and assist the Controlling Party in the defense of such Third Party Action.

(c) Within 20 days after delivery of a Claim Notice, the Indemnifying Party shall deliver to the Indemnified Party a Response, in which the Indemnifying Party shall: (i) agree that the Indemnified Party is entitled to receive all of the Claimed Amount (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Claimed Amount, by check or by wire transfer; provided that if the Indemnified Party is the Buyer and is seeking to enforce such claim pursuant to the Escrow Agreement, the Indemnifying Party and the Indemnified Party shall deliver to the Escrow Agent, within three days following the delivery of the Response, a written notice executed by the Buyer and the Seller Representative instructing the Escrow Agent to distribute to the Buyer such number of Escrow Shares as have an aggregate Value equal to the Claimed Amount), (ii) agree that the Indemnified Party is entitled to receive the Agreed Amount (in which case the Response shall be accompanied by a payment by the Indemnifying Party to the Indemnified Party of the Claimed Amount, by check or by wire transfer; provided that if the Indemnified Party is the Buyer and is seeking to enforce such claim pursuant to the Escrow Agreement, the Indemnifying Party and the Indemnified Party shall deliver to the Escrow Agent, within three days following the delivery of the Response, a written notice executed by the Buyer and the Seller Representative instructing the Escrow Agent to distribute to the Buyer such number of Escrow Shares as have an aggregate Value equal to the Claimed Amount) or (iii) dispute that the Indemnified Party is entitled to receive any of the Claimed Amount. If no Response is delivered by the Indemnifying Party within such 20-day period, the Indemnifying Party shall be deemed to have agreed that all of the Claimed Amount is owed to the Indemnified Party. Acceptance by the Indemnified Party of partial payment of any Claimed Amount shall be without prejudice to the Indemnified Party’s right to claim the balance of any such Claimed Amount. For purposes of this Article V, the “Value” of any Escrow Shares delivered in satisfaction of an indemnity claim shall be the average of the last reported sale prices per share of the Buyer Common Stock on NASDAQ over the five consecutive trading days ending two trading days before such Escrow Shares are distributed by the Escrow Agent to the Buyer as provided above (subject to equitable adjustment in the event of any stock split, stock dividend, reverse stock split or similar event affecting the Buyer Common Stock since the beginning of such five-day period), multiplied by the number of such Escrow Shares.

(d) Any Dispute shall be resolved in accordance with Section 8.12. If the Indemnified Party is the Buyer and the Buyer seeks to enforce the claim that is the subject of the Dispute pursuant to the Escrow Agreement, the Seller Representative and the Buyer shall deliver to the Escrow Agent, promptly following the resolution of the Dispute (whether by mutual agreement, judicial decision or otherwise), a written notice executed by both parties instructing the Escrow Agent as to what (if any) portion of the Escrow Account shall be distributed to the Buyer (which notice shall be consistent with the terms of the resolution of the Dispute).

(e) Without limitation of Section 1.6, the Seller Representative shall have full power and authority on behalf of each Seller to take any and all actions on behalf of, execute any and all instruments on behalf of, and execute or waive any and all rights of, the Sellers under this Article V. The Seller Representative shall have no liability to any Sellers for any action taken or omitted on behalf of the Sellers pursuant to this Article V.

5.4 Limitations.

(a) (i) With respect to claims for Damages arising under Section 5.1(a)(i) or Section 5.1(a)(ii), the Sellers shall not be liable for any such Damages until the aggregate amount of all such Damages exceeds $200,000 (the “Basket”) (at which point the Sellers shall become liable only for Damages under Section 5.1(a)(i) or Section 5.1(a)(ii) in excess of the Basket) and (ii) with respect to claims for Damages arising under Section 5.1(b)(i), the Buyer shall not be liable for any such Damages until the aggregate amount of all such Damages exceeds the Basket (at which point the Buyer shall become liable only for Damages under Section 5.1(b)(i) in excess of the Basket); provided that the limitation set forth in this sentence shall not apply to (A) claims based on fraud or (B) any claim relating to a breach of any of the Fundamental Representations.

(g) Notwithstanding anything to the contrary in this Agreement, for purposes of determining (i) whether there has been a breach of any representation or warranty set forth in Article II, Article III or Article IV and (ii) the amount of Damages for which any Indemnified Party may be entitled to indemnification under this Article V, each such representation or warranty (other than the representations and warranties set forth in Section 3.6(a) or Section 4.8(a)) shall be deemed to have been made without any qualifications or limitations as to materiality (including any qualifications or limitations made by reference to a Company Material Adverse Effect).

This Agreement (including the Ancillary Agreements and the documents and instruments referred to herein) constitutes the entire agreement among the parties to this Agreement and supersedes any prior understandings, agreements or representations by or among the parties hereto, or any of them, written or oral, with respect to the subject matter hereof; provided that the Confidentiality Agreement shall remain in effect in accordance with its terms.

8.3 Fees and Expenses. Except as otherwise expressly provided herein, the Buyer will pay all fees and expenses (including legal and accounting fees and expenses) incurred by it in connection with the transactions contemplated hereby and the Company Transaction Expenses and any Employee Amounts unpaid as of the Closing shall be paid by the Sellers, and for greater certainty, no Company Transaction Expenses shall be claimed as a deduction in determining the Taxes of the Company or Subsidiary. Each Seller shall be responsible for payment of all sales or transfer Taxes (including real property transfer Taxes) arising out of the conveyance of the Shares owned by such Seller.

8.4 Amendment. This Agreement may be mutually amended by the Buyer, the Company and the Seller Representative (on behalf of the Sellers) at any time. This Agreement may not be amended except by an instrument in writing signed (a) in the case of an amendment of any of Section 1.6, Section 1.9, Article V, Article VII and this Article VIII, on behalf of each of the parties hereto, and (b) in the case of an amendment of any other provision of this Agreement, on behalf of the Buyer, the Company and the Seller Representative.

8.5 Third-Party Beneficiaries. This Agreement is not intended to, and shall not, confer upon any other Person any rights or remedies hereunder, except that the Buyer Indemnified Parties shall be third-party beneficiaries of Article V.

8.6 Assignment. Subject to the proviso set forth in Section 1.9(g), neither this Agreement nor any of the rights, interests or obligations under this Agreement may be assigned or delegated, in whole or in part, by operation of Law or otherwise by any of the parties hereto without the prior written consent of the other parties, and any such assignment without such prior written consent shall be null and void, except that the Buyer may transfer or assign its rights and obligations under this Agreement, in whole or from time to time in part, to one (1) or more of its

- 73 -

Affiliates. Subject to the preceding sentence, this Agreement shall be binding upon, inure to the benefit of, and be enforceable by, the parties hereto and their respective successors and permitted assigns.

8.7 Severability. Any term or provision of this Agreement that is invalid or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation or in any other jurisdiction. If the final judgment of a court of competent jurisdiction declares that any term or provision hereof is invalid or unenforceable, the parties hereto agree that the court making such determination shall have the power to limit the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, and this Agreement shall be enforceable as so modified. In the event such court does not exercise the power granted to it in the prior sentence, the parties hereto agree to replace such invalid or unenforceable term or provision with a valid and enforceable term or provision that will achieve, to the extent possible, the economic, business and other purposes of such invalid or unenforceable term.

8.8 Counterparts and Signature. This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original but all of which together shall be considered one (1) and the same agreement and shall become effective when counterparts have been signed by each of the parties hereto and delivered to the other parties, it being understood that all parties need not sign the same counterpart. This Agreement may be executed and delivered by facsimile or by an electronic scan delivered by electronic transmission.

8.9 Interpretation. Except where expressly stated otherwise in this Agreement, the following rules of interpretation apply to this Agreement: (a) “either” and “or” are not exclusive and “include,” “includes” and “including” are not limiting; (b) “hereof,” “hereto,” “hereby,” “herein” and “hereunder” and words of similar import when used in this Agreement refer to this Agreement as a whole and not to any particular provision of this Agreement; (c) “date of this Agreement” refers to the date set forth in the initial caption of this Agreement; (d) “extent” in the phrase “to the extent” means the degree to which a subject or other thing extends, and such phrase does not mean simply “if”; (e) the descriptive headings and table of contents included herein are included for convenience only and shall not affect in any way the meaning or interpretation of this Agreement or any provision hereof; (f) definitions contained in this Agreement are applicable to the singular as well as the plural forms of such terms; (g) references to a contract or agreement mean such contract or agreement as amended or otherwise supplemented or modified from time to time; (h) references to a Person are also to its permitted successors and assigns; (i) references to an “Article,” “Section,” “Exhibit” or “Schedule” refer to an Article or Section of, or an Exhibit or Schedule to, this Agreement; (j) references to “$” or otherwise to dollar amounts refer to the lawful currency of the United States; (k) references to a federal, state, local or foreign Law include any rules, regulations and delegated legislation issued thereunder; (l) references to accounting terms used and not otherwise defined herein have the meaning assigned to them under GAAP; and (m) a term that begins with an initial capital letter, is not defined herein and reflects a different part of speech than a term that begins with an initial

- 74 -

capital letter and is defined herein, shall be interpreted in a correlative manner. When reference is made in this Agreement to information that has been “made available” to the Buyer, that shall consist of only the information that was (i) contained in the Company’s electronic data room no later than 5:00 p.m., Eastern time, on the second (2nd) Business Day prior to the date of this Agreement or (ii) delivered to the Buyer or its counsel. The language used in this Agreement shall be deemed to be the language chosen by the parties hereto to express their mutual intent, and no rule of strict construction shall be applied against any party hereto. No summary of this Agreement prepared by any party shall affect the meaning or interpretation of this Agreement. If any date on which a party is required to make a payment or a delivery pursuant to the terms hereof is not a Business Day, then such party shall make such payment or delivery on the next succeeding Business Day. Time shall be of the essence in this Agreement.

8.10 Governing Law. This Agreement (and any claims or disputes arising out of or related hereto or the transactions contemplated hereby or to the inducement of any party to enter herein, whether for breach of contract, tortious conduct or otherwise and whether predicated on common law, statute or otherwise) shall be governed in all respects, including validity, interpretation, and effect, by and construed in accordance with the internal Laws of the State of Delaware (including in respect of the statute of limitations or other limitations period applicable to any claim, controversy or dispute) without giving effect to any choice or conflict of Law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of Laws of any jurisdictions other than those of the State of Delaware; provided, that this Agreement will be governed by and construed in accordance with the laws of the Province of Ontario and the federal laws of Canada applicable therein solely to the extent necessary to effect the purchase by the Buyer and the sale by the Sellers of the Company Shares and the transactions related thereto.

8.11 Remedies.

(a) Except as otherwise provided in Section 5.4(h) with respect to the period from and after the Closing, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by Law or equity upon such party, and the exercise by a party of any one (1) remedy will not preclude the exercise of any other remedy.

(b) The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case without posting a bond or undertaking, this being in addition to any other remedy to which they are entitled at Law or in equity. Each of the parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief on the basis that (i) the party seeking such remedy has an adequate remedy at Law or (ii) an award of specific performance is not an appropriate remedy for any reason at Law or equity.

8.12 Submission to Jurisdiction. Each of the parties to this Agreement (a) consents to submit itself to the exclusive personal jurisdiction of the Court of Chancery of the State of Delaware, New Castle County, or, if that court does not have jurisdiction, a federal court sitting in Wilmington, Delaware in any action or proceeding arising out of or relating to this Agreement or any of the transactions contemplated by this Agreement, (b) agrees that all claims in respect of such action or proceeding may be heard and determined in any such court, (c) agrees that it shall not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (d) agrees not to bring any action or proceeding arising out of or relating to this Agreement or any of the transactions contemplated by this Agreement in any other court, and (e) waives any right it may have to a trial by jury with respect to any action or proceeding arising out of or relating to this Agreement. Each of the parties hereto waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other party with respect thereto. Any party hereto may make service on another party by sending or delivering a copy of the process to the party to be served at the address and in the manner provided for the giving of notices in Section 8.1. Nothing in this Section 8.12, however, shall affect the right of any party to serve legal process in any other manner permitted by Law.

8.13 Disclosure Schedules. Each of the Company Disclosure Schedule and the Buyer Disclosure Schedule shall be arranged in sections corresponding to the numbered sections contained in this Agreement, and the disclosure in any section shall qualify only (a) the corresponding section of this Agreement and (b) the other sections of this Agreement to the extent that it is reasonably apparent from a reading of such disclosure that it also qualifies or applies to such other sections. The inclusion of any information in the Company Disclosure Schedule or the Buyer Disclosure Schedule, as applicable, shall not be deemed to be an admission or acknowledgment, in and of itself, that such information is required by the terms hereof to be disclosed, is material, has resulted in or would result in a Company Material Adverse Effect or a Buyer Material Adverse Effect, as applicable, or is outside the Ordinary Course of Business.
