7.3 Indemnification by Buyer.  Subject to the other provisions of this Article 7, Buyer will indemnify, defend and hold harmless Seller and its Affiliates and their respective officers, directors and shareholders (collectively, the "Seller Indemnified Parties") for any Damages, to the extent caused by or arising from:

(a) any inaccuracy or breach of any representation or warranty of Buyer in this Agreement;

(b) any breach or non-fulfillment by Buyer of any covenant or agreement of Buyer in this Agreement; or

(c) any Assumed Liabilities.

7.4 Time Limitations.  Notwithstanding Section 7.1 above, any claims asserted in good faith specifying the factual basis of that claim in reasonable detail to the extent then known by such Party and delivered in writing by notice from the non-breaching party to the breaching party prior to the expiration date of the applicable survival period shall not thereafter be barred by the expiration of such survival period and such claims shall survive until finally resolved. Buyer or Seller may make a claim for breach of a post-Closing covenant, Excluded Assets, Purchased Assets, Excluded Liability or Assumed Liability, as applicable, any time after it has been determined by such Party that there has been a breach or an indemnification claim for an Excluded Liability or Assumed Liability. Any claim for indemnification under Article 7, which is not a Third Party Claim shall (if not previously satisfied, settled or withdrawn) be deemed to have been withdrawn by the Indemnified Person making such claim unless formal legal proceedings in respect of such claim have been commenced in accordance with this Agreement within twelve (12) months of notification to the Indemnifying Party of such claim.

7.5 Limitations on Amount.  The Indemnified Persons (as defined below) will have no liability with respect to the matters described in Section 7.2(a) or 7.3(a), as applicable unless and until (a) the individual claim giving rise to any Damages exceeds [**] (an "Indemnifiable Claim") and (b) the aggregate amount of all such Indemnifiable Claims exceeds [**] percent ([**]%) of the Purchase Price (the "Deductible Amount"), in which case the Indemnified Persons shall be liable for the aggregate amount of all such Indemnifiable Claims in excess of the Deductible Amount. Notwithstanding the foregoing, the Indemnified Persons will have no liability (for indemnification or otherwise) with respect to the matters described in Section 7.2(a) or 7.3(a), as applicable, once the aggregate dollar amount of all Damages indemnified under Section 7.2(a) or 7.3(a), as applicable, equals (x) [**] percent ([**]%) of the Purchase Price plus (y) solely with respect to the representations and warranties contained in Section 3.9 (other than those in Section 3.9(b)), an additional [**] percent ([**]%) of the Purchase Price. For the avoidance of doubt, Seller's total aggregate liability (for indemnification or otherwise) pursuant to the immediately preceding sentence shall be limited to [**] percent ([**]%) of the Purchase Price. Notwithstanding the foregoing, the limitations in this Section 7.5 shall not apply to claims of common law fraud or claims relating to any inaccuracy or breach of the Fundamental Representations or the Buyer Fundamental Representations; provided, however, that, except in the case of common law fraud, the Indemnified Persons will have no liability relating to any inaccuracy or breach of the Fundamental Representations or the Buyer Fundamental Representations in excess of the Purchase Price.  Notwithstanding the foregoing, for the purposes of calculating the amount of any Damages hereunder, the representations and warranties shall be read without regard to any Material Adverse Effect or other materiality qualifiers contained therein.

7.6 Procedure for Indemnification.

(a) All claims for indemnification by a Buyer Indemnified Party or any Seller Indemnified Party (collectively, the "Indemnified Persons") pursuant to this Article 7 shall be made in accordance with the provisions of this Agreement.

(b) If a Third Party asserts that an Indemnified Person is liable to such Third Party for a monetary or other obligation which may constitute or result in Damages for which such Indemnified Person may be entitled to indemnification pursuant to this Article 7, then such Indemnified Person may make a claim for indemnification pursuant (a "Third Party Claim") to this Article 7 and shall be reimbursed in accordance with the applicable provisions of this Agreement for any such Damages for which it is entitled to indemnification pursuant to this Article 7 (subject to the right of the Indemnifying Party to dispute the Indemnified Person's entitlement to indemnification under the applicable terms of this Agreement). For purposes of this Agreement, "Indemnifying Party" means (i) in the case of a claim for indemnification by Buyer, Seller and (ii) in the case of a claim for indemnification by Seller, Buyer.

(c) The Indemnified Person shall give prompt written notification to the Indemnifying Party of the assertion of any Third Party Claim (including the commencement of any Proceeding relating to a Third Party Claim) for which indemnification pursuant to this Article 7 may be sought; provided, however, that no delay on the part of the Indemnified Person in notifying the Indemnifying Party, as the case may be, shall relieve the Indemnified Person of any liability or obligation hereunder except to the extent of any Damage or Liability caused by or arising out of such failure.  Within thirty (30) days after delivery of such notification, the Indemnifying Party may, upon written notice thereof to the Indemnified Person, assume control of the defense of such Proceeding (with counsel reasonably satisfactory to the Indemnified Person) of any such Third Party Claim seeking (i) solely monetary Damages, (ii) injunctive relief that would be reasonably expected to be immaterial to the operations or business of the Indemnified Person and monetary Damages or (iii) if Seller is the Indemnifying Party, Damages (including monetary Damages) where the amount of Damages expected to arise from such Third Party Claim are, after a reasonable assessment by Seller made in good faith, not reasonably anticipated to exceed [**] of the respective maximum amount indemnifiable by Seller in respect of a claim of such nature pursuant to Section 7.5; provided that prior to the assumption of the defense of any Third Party Claim, the Indemnifying Party shall provide a written undertaking confirming that, as between the Indemnified Person and the Indemnifying Party, any Damages related to such Third Party Claim, up to the maximum amount of the Indemnifying Party's indemnification obligations of the respective maximum amount indemnifiable by Seller in respect of a claim of such nature pursuant to Section 7.5, shall be the sole responsibility of the Indemnifying Party.  If the Indemnifying Party does not assume control of such defense, the Indemnified Person shall control such defense. The Party not controlling such defense may participate therein at its own expense; provided that if the Indemnifying Party assumes control of such defense and the Indemnified Person, upon the written advice of external counsel, reasonably concludes that Seller and the Indemnified Person have conflicting interests with respect to such action, suit, proceeding or claim, the reasonable fees and expenses of counsel to the Indemnified Person solely in connection therewith shall be considered "Damages" for purposes of this Agreement; provided, however, that in no event shall the Indemnifying Party be responsible for the fees and expenses of more than one (1) counsel for the Indemnified Person.  The Party controlling such defense shall keep the other Party advised of the status of such Proceeding and the defense thereof.  The Indemnified Person shall not agree to any settlement of such Proceeding without the prior written consent the Indemnifying Party, which shall not be unreasonably withheld, conditioned or delayed.  The Indemnifying Party shall not agree to any settlement of such Proceeding that does not include a complete release of the Indemnified Person from all liability with respect thereto or that imposes any liability or obligation on the Indemnified Person without the prior written consent of the Indemnified Person, which shall not be unreasonably withheld, conditioned or delayed.

7.7 Satisfaction and Treatment of Indemnity Payments.

(a) In the event that Seller is required to provide indemnification hereunder to any Buyer Indemnified Parties, such indemnification obligation shall be paid to Buyer (for further distribution between Buyer and other Buyer Indemnified Parties, as appropriate).  Any payment made to Buyer pursuant to this Article 7 shall be treated as a reduction in the Adjusted Purchase Price for Tax purposes, unless otherwise required by applicable Legal Requirements.

(b) In the event that Buyer is required to provide indemnification hereunder to Seller Indemnified Parties, such indemnification obligation shall be paid to Seller (for further distribution between Seller and other Seller Indemnified Parties, as appropriate).  Any payment made to Seller pursuant to this Article 7 shall be treated as an increase in the Adjusted Purchase Price for Tax purposes.

7.8 Right to Satisfy Indemnification Claims by Reducing Future Milestone Payments.  Buyer is expressly authorized, but shall not be obligated, to set off up to [**] of any undisputed Damages it is entitled to receive from Seller pursuant to, and subject to the indemnification provisions of, this Article 7, against any Milestone Payment.  For the avoidance of doubt, Buyer shall not be permitted to set-off any Damages owing under this Agreement against any amount due under the Supply Agreement.

7.9 Certain Other Limitations.

(a) Notwithstanding anything to the contrary in this Agreement, the amount of any Damages for which indemnification is provided under this Article 7 shall be net of (i) any actual cash insurance recoveries and (ii) any amounts actually recovered by the Indemnified Person from a Third Party in connection with a claim.  A Party shall have an obligation to use commercially reasonable efforts to seek an insurance recovery.  If a Party obtains a recovery, the Party's indemnity claim shall not be offset to the extent of the Party's expenses in obtaining such recovery.  An insurer who is otherwise obligated to pay a claim is not relieved of the responsibility with respect to the claim and has no subrogation rights with respect to the claim, in either instance, solely by virtue of the indemnification provisions of this Article 7.  A Party that provides indemnification hereunder is subrogated to the rights of an Indemnified Person upon payment of the relevant indemnity claim.

(b) An Indemnified Person shall take all reasonable steps to mitigate any Damages as required under applicable law incurred by such Party after becoming aware of any event or condition that would reasonably be expected to give rise to any indemnification rights hereunder.  Notwithstanding the immediately preceding sentence, no Party shall be liable for any Damages to the extent the Buyer Indemnified Parties or the Seller Indemnified Parties, as applicable, failed to take those steps required by applicable law to mitigate Damages.

(c) No Party shall have any liability for (i) an otherwise indemnifiable Damage that is contingent unless and until such contingent Damage becomes an actual Damage of the Indemnified Person and is due and payable, so long as the claim for such Damage was timely submitted pursuant to the provisions of this Article 7; or (ii) any Damages to the extent arising from (x) a change in accounting or taxation law, policy or practice made after the Closing, or (y) any law not in force on the Closing Date.

(d) NOTWITHSTANDING ANYTHING TO THE CONTRARY HEREIN, IN NO EVENT SHALL ANY PARTY HERETO OR ITS AFFILIATES BE LIABLE OR RESPONSIBLE TO THE OTHER PARTY HERETO FOR INCIDENTAL, SPECIAL, CONSEQUENTIAL OR PUNITIVE DAMAGES, INCLUDING WITHOUT LIMITATION ANY CLAIM FOR DAMAGES BASED UPON LOST REVENUES OR PROFITS, HOWEVER CAUSED OR ON ANY THEORY OF LIABILITY THAT ARISE OUT OF OR RELATE TO THIS AGREEMENT OR THE PERFORMANCE OR BREACH THEREOF, EXCEPT IN THE CASE OF COMMON LAW FRAUD OR WILLFUL MISCONDUCT. FOR THE AVOIDANCE OF DOUBT, ANY DAMAGES AWARDED TO A THIRD PARTY FOR WHICH A PARTY IS OBLIGATED TO INDEMNIFY THE OTHER PARTY IN ACCORDANCE WITH THIS ARTICLE 7 SHALL BE CONSIDERED DIRECT DAMAGES.  NOTHING IN THIS SECTION 7.9(D) SHALL CONSTITUTE A WAIVER OF DAMAGES TO THE EXTENT THOSE DAMAGES ARE DIRECT DAMAGES.

7.10 Indemnification Exclusive Remedy.  Except for claims arising from common law fraud, Buyer and Seller acknowledge and agree that their sole and exclusive remedy with respect to any and all Damages relating to the subject matter of this Agreement, or otherwise regarding the transactions contemplated by this Agreement, shall be pursuant to the indemnification provisions set forth in this Article 7.  In furtherance of the foregoing, except in the case of common law fraud, Buyer hereby waives, to the fullest extent permitted under applicable law, any and all rights, claims and causes of action it may have against Seller in law or equity, except such rights, claims and causes of action based upon Buyer's right to indemnification under this Agreement, and Seller hereby waives, to the fullest extent permitted under applicable law, any and all rights, claims and causes of action each may have against Buyer in law or equity except such rights, claims and causes of action based upon Seller's right to indemnification under this Agreement; provided, however, that in addition to such indemnification, the Parties may seek equitable remedies, including specific performance in accordance with applicable Legal Requirements, as set forth in Section 10.10.  Nothing in this Section 7.10 shall limit Buyer or Seller from exercising any remedy provided for or permitted under any Other Transaction Documents pursuant to the terms of such Other Transaction Documents.

ARTICLE 8

8.1 Termination.  Prior to the Closing, this Agreement shall terminate on the earliest to occur of any of the following events:

(a) the mutual written agreement of Buyer and Seller;

(b) by written notice delivered by either Buyer or Seller to the other, if the Closing shall not have occurred on or prior to [**] (the "End Date") (other than due to a breach of any representation or warranty hereunder of the Party seeking to terminate this Agreement or as a result of the failure on the part of such Party to comply with or perform any of its covenants, agreements or obligations under this Agreement and other than as a result of any closing condition in favor of the non-terminating Party not being satisfied, which closing condition has been waived by the non-terminating Party); provided, however, that, if the Closing shall not have occurred on or prior to [**]; provided, further, that (a) Buyer shall not have the right to terminate this Agreement pursuant to this Section 8.1(b) during the pendency of any Proceeding brought prior to the End Date by Seller for specific performance of this Agreement and (b) Seller shall not have the right to terminate this Agreement pursuant to this Section 8.1(b) during the pendency of any Proceeding brought before the End Date by Buyer for specific performance of this Agreement;

(e) by written notice delivered by Seller to Buyer, if (i) all of the conditions set forth in Section 6.2 and Section 6.3 have been satisfied and remain satisfied (other than those conditions that (a) by their terms are to be satisfied at the Closing or (b) the failure of which to be satisfied is attributable to a breach by Buyer of its representations, warranties, covenants or agreements contained in this Agreement), (ii) Seller has irrevocably confirmed by written notice to Buyer that (A) all conditions set forth in Section 6.2 have been satisfied or that it is willing to waive any unsatisfied conditions set forth in Section 6.2 and (B) if Buyer performs its obligations hereunder then Seller is prepared to cause the Closing to occur, and (iii) the transactions contemplated hereunder shall not have been consummated within two (2) Business Days after delivery of such notice; provided, however, that such conditions remain satisfied and such confirmation remains in full force and effect at the close of business on such second (2nd) Business Day;

(g) by either Seller or Buyer, by giving written notice of such termination to the other Party, if any court of competent jurisdiction or other Governmental Body having jurisdiction over the Parties shall have issued an order or judgment or taken any other action permanently restraining, enjoining or otherwise prohibiting the transactions contemplated by this Agreement and such order or other action shall have become final and non-appealable; provided, however, in each case, that the right to terminate this Agreement pursuant to this Section 8.1(f) shall not be available to either Party whose breach of any of its representations, warranties, covenants or agreements contained herein has resulted in the circumstances giving rise to the right to terminate this Agreement pursuant to this Section 8.1(f); or

(h) by either Seller or Buyer, by giving written notice of such termination to the other Party, if an [**] would be necessary in order to obtain a required clearance or approval from a Competition Authority to consummate the transactions contemplated hereunder.

(c) Withdrawal of Certain Filings.  As soon as practicable following a termination of this Agreement for any reason, but in no event more than thirty (30) days after such termination, Buyer or Seller shall, to the extent practicable, withdraw all filings, applications and other submissions relating to the transactions contemplated by this Agreement filed or submitted by or on behalf of such Party, any Governmental Body or other Person.

ARTICLE 9
DISPUTE RESOLUTION

9.1 Mandatory Procedures.  The Parties agree that any dispute arising out of or relating to this Agreement shall be resolved solely by means of the procedures set forth in this Article 9, and that such procedures constitute legally binding obligations that are an essential provision of this Agreement.

9.2 Negotiation.  The Parties shall endeavor to resolve in good faith any disputes or conflict arising from or relating to the subject matter of this Agreement, failing which either Party may submit such dispute for resolution to appropriate senior management of Buyer and Seller.  If such senior management representatives are unable to resolve such dispute within thirty (30) days after such conflict is submitted to them for resolution, either Party shall refer the dispute for mediation as set forth in Section 9.3.

9.3 Mediation.  If the Parties are unable to resolve a dispute arising out of or relating to this Agreement through the negotiation procedures set forth in Section 9.2, then at the end of such thirty (30) day period, the Parties agree that they shall submit such dispute for confidential mediation to be held in New York, New York under the CPR Mediation Procedure then in effect at the start of mediation with the International Institute for Conflict Prevention & Resolution (www.cpradr.org) (the "CPR").  Unless otherwise agreed, the Parties shall select a mediator from the CPR Panels of Distinguished Neutrals.  If the Parties cannot agree, they shall defer to the CPR to select a mediator.  The cost of the mediator shall be borne equally by the Parties.  Any dispute not resolved within forty-five (45) days (or within such other time period as may be agreed to by the Parties in writing) after appointment of a mediator shall be finally resolved by arbitration pursuant to Section 9.4.

9.4 Arbitration.  If the Parties are unable to resolve a dispute arising out of or relating to this Agreement through the negotiation procedures set forth in Section 9.2 and the mediation procedures set forth in Section 9.3 within the timeframes set forth in such Sections, the Parties agree that they shall submit such dispute for final settlement via binding arbitration.  The arbitration shall be conducted under the Commercial Arbitration Rules (the "Rules") of the American Arbitration Association (the "AAA") in effect at the time of commencement of the arbitration, except as they may be modified herein or by mutual agreement of the Parties, and heard before a single arbitrator agreed upon by the Parties.  If the Parties are unable to agree on the single arbitrator within fifteen (15) Business Days from the date on which the Demand for Arbitration is served on the respondent (as such term is defined in the Rules), then the single arbitrator shall be appointed by the AAA from the AAA National Roster of Arbitrators and Mediators.  The arbitration shall be held in New York, New York and shall be conducted in English.  Each Party shall be responsible for its own expenses in connection therewith; except that the fees and costs of the AAA and the arbitrator, the costs and expenses of obtaining the facility where the arbitration hearing is held, and such other costs and expenses as the arbitrator may determine to be directly related to the conduct of the arbitration (which shall not include any party's attorneys' fees or costs, witness fees (if any), costs of investigation and similar expenses) shall be shared equally by the Parties. The Parties hereby submit to the non-exclusive jurisdiction of the United States District Court for the Southern District of New York for the limited purpose of enforcing this Agreement to arbitrate. The arbitration award shall be final and binding, and judgment over the award may be entered by any court having jurisdiction thereof or having jurisdiction over the relevant Party or its assets.

9.5 Interim Relief.  Notwithstanding the foregoing, nothing contained in Section 9.3 or 9.4 shall prohibit a Party from seeking or obtaining temporary relief from any court of competent jurisdiction pending the outcome of mediation or the arbitration award in any dispute relating to or arising out of this Agreement.

ARTICLE 10
GENERAL PROVISIONS

10.1 Expenses.  Except as otherwise expressly provided in this Agreement, each Party to this Agreement will bear its respective expenses incurred in connection with the preparation, execution, and performance of this Agreement and the transactions contemplated hereby, including all fees and expenses of agents, representatives, counsel, and accountants.  In the event of termination of this Agreement, the obligation of each Party to pay its own expenses will be subject to any rights of such Party arising from a breach of this Agreement by the other Party.

10.2 Public Announcements.

(a) Except for the press release attached hereto as Appendix IX, no public announcement or similar publicity with respect to this Agreement or the transactions contemplated hereby will be issued, if at all, unless (i) consistent with, and no broader than, (x) the press release attached hereto as Appendix IX or (y) the investor call script and the "Q&A" document provided to Seller in final form and approved on or about July 18, 2017, or (ii) unless consented to in advance in writing by both Parties.  Prior to the Closing, Buyer and Seller shall keep this Agreement strictly confidential and may not make any disclosure of this Agreement to any Person.

(b) Except for the press release attached hereto as Appendix IX, each of Buyer and Seller agree that the terms of this Agreement and the Other Transaction Documents shall not be disclosed or otherwise made available to the public and that copies of this Agreement, the press release attached hereto as Appendix VIII and the Other Transaction Documents shall not be publicly filed or otherwise made available to the public, except where such disclosure, availability or filing is required by applicable Legal Requirement or stock exchange requirement.  In the event that such disclosure, availability or filing is required by applicable Legal Requirement or stock exchange requirement, each of Buyer and Seller (as applicable) agrees to promptly notify the other Party and to use commercially reasonable efforts to obtain "confidential treatment" of this Agreement and the Other Transaction Documents with the U.S. Securities and Exchange Commission (or the equivalent treatment by any other Governmental Body) and to redact such terms of this Agreement and the Other Transaction Documents as the other Party shall reasonably request to the extent allowable under applicable Legal Requirements.  Buyer shall provide Seller the opportunity to review all disclosures, availabilities or filings for which Buyer is seeking "confidential treatment" with the U.S. Securities and Exchange Commission (or the equivalent treatment by any other Governmental Body), including the Current Report on Form 8-K which Buyer will file on or shortly after the date hereof, and shall consider in good faith all of Seller's reasonable comments thereto. Each Party shall be permitted to disclose the terms of this Agreement, in each case under appropriate confidentiality provisions substantially equivalent (in no event be required to be more restrictive than) to those of this Agreement and the Confidentiality Agreement, to any actual or potential acquirers, merger partners, collaboration partners, alliance partners, sublicensees, licensees and professional advisors.

10.4 Further Assurances.  Each of Seller and Buyer agree, at the request and expense of the other, to (a) furnish upon request to each other such further information, (b) execute and deliver to each other such other documents, and (c) do such other acts and things, in each case as the other Party may reasonably request for the purpose of carrying out the intent of this Agreement and the Other Transaction Documents and which are consistent with the terms of this Agreement and the Other Transaction Documents.

10.5 Waiver.  The rights and remedies of the Parties to this Agreement are cumulative and not alternative.  Neither the failure nor any delay by any Party in exercising any right, power, or privilege under this Agreement or the documents referred to in this Agreement will operate as a waiver of such right, power, or privilege, and no single or partial exercise of any such right, power, or privilege will preclude any other or further exercise of such right, power, or privilege or the exercise of any other right, power, or privilege.  To the maximum extent permitted by applicable law: (a) no claim or right arising out of this Agreement or the documents referred to in this Agreement can be discharged by a Party, in whole or in part, by a waiver or renunciation of the claim or right unless in writing signed by the other Party; (b) no waiver that may be given by a Party will be applicable except in the specific instance for which it is given; and (c) no notice to or demand on a Party will be deemed to be a waiver of any obligation of such Party or of the right of the Party giving such notice or demand to take further action without notice or demand as provided in this Agreement or the documents referred to in this Agreement.

10.6 Entire Agreement and Modification.  This Agreement supersedes all prior agreements between the Parties with respect to its subject matter and constitutes (along with the documents referred to in this Agreement) a complete and exclusive statement of the terms of the agreement between the Parties with respect to its subject matter.  This Agreement may not be amended or modified except by a written agreement duly executed by each of the Parties hereto.  Emails, including emails that bear an electronic "signature block" identifying sender, do not constitute a signed instrument for the purposes of this Agreement.

10.7 Disclosure Schedule.  The information and disclosures in the Disclosure Schedule are intended only to qualify and limit the representations and warranties of Seller contained in this Agreement and shall not be deemed to expand in any way the scope or effect of any of such representations and warranties.  The Section numbers in the Disclosure Schedule correspond to the section numbers in this Agreement.  Capitalized terms used but not defined in the Disclosure Schedule shall have the same meanings given them in this Agreement.  In the event of any inconsistency between the statements in the body of this Agreement and those in the Disclosure Schedule (other than an exception expressly set forth as such in the Disclosure Schedule with respect to a specifically identified representation or warranty), the statements in the body of this Agreement will control.

10.8 Assignments, Successors and No Third-Party Rights.  No Party may assign this Agreement or any of its rights or obligations under this Agreement without the prior consent of the other Party, and any purported assignment without a consent shall be void; provided, however, that either Party may, in its sole discretion and without any consent of the other Party, assign this Agreement or any of its rights or obligations hereunder, in whole or in part, to an Affiliate or to any Person that acquires all or substantially all of the assets and business of such Party (whether such acquisition is structured as a sale of equity, a sale of assets, a merger or otherwise) with or without the consent of the other Party, provided that the assigning Party shall not be relieved of its obligations under this Agreement but shall be jointly and severally liable with the assignee hereunder.  Subject to the preceding sentence, this Agreement will apply to, be binding in all respects upon, and inure to the benefit of the successors and permitted assigns of the Parties.  Nothing expressed or referred to in this Agreement will be construed to give any Person other than the Parties to this Agreement (and, under Article 7, the other Buyer Indemnified Parties and Seller Indemnified Parties) any legal or equitable right, remedy, or claim under or with respect to this Agreement or any provision of this Agreement.  This Agreement and all of its provisions and conditions are for the sole and exclusive benefit of the Parties to this Agreement, their successors and permitted assigns and, under Article 7, the other Buyer Indemnified Parties and Seller Indemnified Parties.

10.9 Severability.  If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement will remain in full force and effect.  Any provision of this Agreement held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable.

10.10 Specific Performance.  The Parties agree that irreparable damage could occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms (including failing to take such actions as are required of them hereunder to consummate this Agreement) or were otherwise breached.  It is accordingly agreed that a Party shall be entitled to seek an injunction or injunctions, specific performance or other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement without proof of damages or otherwise in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which it is entitled at law or in equity.  Each Party hereby waives (a) any requirement that the other Party post a bond or other security as a condition for obtaining any such relief, and (b) any defenses in any action for specific performance, including the defense that a remedy at law would be adequate.  The Parties agree that the right of specific performance is an integral part of the transactions contemplated by this Agreement and without this right, neither Seller nor Buyer would have entered into this Agreement.

This Agreement was negotiated by the Parties with the benefit of legal representation, and any rule of construction or interpretation otherwise requiring this Agreement to be construed or interpreted against any Party shall not apply to any construction or interpretation hereof.  In the event of any conflict between the provisions of this Agreement and the provisions of any Other Transaction Document, the provisions of this Agreement shall prevail. When reference is made in Article 3 of this Agreement to information that has been "made available" to Buyer, such information shall consist of only the information that was (a) contained in Seller's electronic data room no later than 11:00 p.m., Eastern time, on July 18, 2017 or (b) delivered or provided to Buyer or its counsel.

10.12 Time of the Essence.  With regard to all dates and time periods set forth or referred to in this Agreement, time is of the essence.
