6.2 Lock-Up.

(a) In consideration of the issuance of the Initial Consideration Shares by NPS, Takeda hereby agrees that, without the prior written consent of NPS, during the period beginning on the Effective Date and continuing to and including the date that is one hundred eighty (180) days after the Effective Date (the “Initial Consideration Shares Lock-Up Period”), Takeda will not (1) offer, pledge, announce the intention to sell, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, make any short sale or otherwise transfer or dispose of, directly or indirectly, the Initial Consideration Shares or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Initial Consideration Shares, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of NPS Common Stock or such other securities, in cash or otherwise. The foregoing restriction is expressly agreed to preclude Takeda from engaging in any hedging or other transaction which is designed to or which reasonably could be expected to lead to or result in a sale or disposition of the Initial Consideration Shares even if such Initial Consideration Shares would be disposed of by someone other than Takeda. Such prohibited hedging or other transactions would include without limitation any short sale or any purchase, sale or grant of any right (including without limitation any put or call option) with respect to any of the Initial Consideration Shares or with respect to any security that includes, relates to, or derives any significant part of its value from the Initial Consideration Shares. Takeda further represents and agrees that Takeda has not taken and will not take, directly or indirectly, any action which is designed to or which has constituted, or which might reasonably be expected to cause or result in, stabilization or manipulation of the price of any security of NPS to facilitate the sale or resale of the Initial Consideration Shares, or which has otherwise constituted or will constitute any prohibited bid for or purchase of the Initial Consideration Shares or any related securities.

(b) Notwithstanding the foregoing restriction on transfer, Takeda may, without the prior written consent of NPS, at any time transfer the Initial Consideration Shares to (1) an Affiliate of Takeda or (2) a successor entity or other Third Party acquirer that acquires all or substantially all of the assets of Takeda; provided, however, that any such transferee, as a condition precedent to such transfer, shall acknowledge and agree in writing to be bound by the terms and conditions contained herein in the same manner as such terms and conditions apply to Takeda.

(c) If, at any time prior to the first anniversary of the Effective Date, an underwriter in a public offering to be conducted by NPS requests that Takeda enter into a lock-up agreement with respect to the Initial Consideration Shares then held by it and all of NPS’ executive officers are also required to enter into a lock-up agreement , Takeda shall enter into a lock-up agreement with such underwriter with respect to the Initial Consideration Shares then held by it on the same terms and conditions as are applicable to NPS’ executive officers (or, if NPS’ executive officers are subject to different terms and conditions, on the least onerous terms and conditions applicable to any of NPS’ executive officers), provided that in no event shall the duration of the lock-up applicable to Takeda exceed ninety (90) days and further provided that Takeda’s agreement to enter into a lock-up agreement shall only be applicable with respect to one public offering completed by NPS during the period commencing as of the Effective Date

and ending on the first anniversary of the Effective Date and if Takeda is not required to sign a lock-up agreement in connection with such completed public offering its obligation under this Section 6.2(c) shall expire. Nothing contained in this Section 6.2(c) shall modify, limit or release Takeda’s obligations under Section 6.2(a). Takeda agrees that NPS may make the request that Takeda enter into the lock-up agreement contemplated by this Section 6.2(c) prior to the public announcement of a contemplated public offering and Takeda will treat the existence of a contemplated public offering as Confidential Information.

7. MILESTONE CONSIDERATION

7.1 Records, Reporting and Audit.

(a) Not later than thirty (30) days after the end of each calendar quarter, commencing with the Initial Quarter, NPS shall report to Takeda the amount of Net Sales, by Product, for such calendar quarter. Each such report shall specify in reasonable detail gross sales and all deductions allowed in the calculation of such Net Sales. As used herein, “Initial Quarter” means the first calendar quarter following the first calendar year in which Net Sales equal or exceed $500,000,000 for such calendar year; provided that if the first calendar year in which Net Sales equal or exceed $500,000,000 for such calendar year is the calendar year in which the Sales Milestone occurs, not later than thirty days (30) days after the end of such calendar year NPS shall report to Takeda the amount of Net Sales, by Product, for such calendar year.

(b) NPS shall keep and maintain (and shall cause its Affiliates, licensees and sublicensees and all Transferees to keep and maintain) complete and accurate records necessary to determine Net Sales and such other information as is necessary to determine whether the Sales Milestone has been achieved, until the later of (i) three (3) years after the period to which such records relate and (ii) such longer period as applicable law requires.

(c) At the request of Takeda, NPS shall, and shall cause its Affiliates, licensees and sublicensees and all Transferees to, permit an independent auditor designated by Takeda and reasonably acceptable to NPS (the “Auditor”), at reasonable times and upon reasonable notice, to audit the books and records maintained pursuant to Section 7.2(b) to ensure the accuracy of all reports made under Section 7.2(a). Such examinations may not: (a) be conducted for any calendar quarter more than three (3) years after the end of such quarter; (b) be conducted more than once in any twelve (12) month period (unless a previous audit during such twelve (12)-month period revealed an inaccuracy with respect to such period); or (c) be repeated for any calendar quarter. The Auditor shall disclose to Takeda only whether any reports made under this Agreement are correct and details concerning any discrepancies. The Auditor shall send a copy of the report to NPS at the same time it is sent to Takeda. The determination of the Auditor shall be final and binding on the Parties, absent manifest error. The cost of such audit shall be borne by Takeda, unless the audit reveals that the Sales Milestone was achieved in a calendar year for which NPS reported that the Sales Milestone was not achieved, in which case NPS shall bear the cost of the audit. If, as a result of any such audit, it is determined that the Sales Milestone has been achieved and the Sales Milestone Date has occurred, then NPS shall make the Sales Milestone Payment in accordance with Section 7.2 not later than fifty (50) days after delivery of the Auditor’s report.

(d) NPS shall notify Takeda of any Qualifying Change of Control not later than ten (10) days after the effective date thereof.

Within fifty (50) days after the Sales Milestone Date (subject to Section 7.1(c)), NPS shall make a one-time payment to Takeda equal to thirty million dollars (US$30,000,000) (such payment, the “Milestone Payment”). NPS’s obligation to make the Milestone Payment shall accelerate and be due within fifty (50) days after the occurrence of a Qualifying Change of Control. The Milestone Payment shall be in the form of either or a combination of (x) a wire transfer of immediately available funds to an account designated by Takeda, and/or (y) if the NPS Common Stock is publicly traded on a Trading Market, at NPS’s sole discretion (but subject to the limitations set forth in Section 7.3), the issuance and sale to Takeda GmbH and Takeda Pharma of such number of shares of NPS Common Stock (or shares of common stock of NPS’ successor or such successor’s parent in the event of an acceleration of the Milestone Payment obligation due to a Qualifying Change of Control if the common stock of such successor or such successor’s parent is publicly traded on a Trading Market), equal to the quotient of (A) thirty million dollars (US$30,000,000) divided by (B) the VWAP of the NPS Common Stock (or common stock of NPS’ successor or such successor’s parent in the event of an acceleration of the Milestone Payment obligation due to a Qualifying Change of Control, as applicable) over the thirty trading (30) days

immediately prior to (but not including) the Sales Milestone Date or the date of the Qualifying Change of Control, as applicable (such shares, the “Milestone Shares”, and together with the Initial Consideration Shares, the “Shares”). The total number of Milestone Shares shall be allocated between Takeda GmbH and Takeda Pharma in such amounts as shall be notified by Takeda to NPS. If NPS elects to pay the Milestone Payment in the form of Milestone Shares, NPS shall give Takeda written notice of such election at least thirty (30) days before the date NPS wishes to effect the closing of the issuance and sale of the Milestone Shares as contemplated by this Section 7.2 (such closing, the “Milestone Shares Closing”). The Milestone Shares Closing shall take place on or before the date mutually agreed by NPS and Takeda, which date shall be not later than the end of the fifty (50) day period referenced in the first or second sentence of this Section, as applicable (or in the last sentence of Section 7.1(c), if applicable) (the date of the Milestone Shares Closing is referred to herein as the “Milestone Shares Closing Date”).

7.3 Limitation on NPS’s Discretion to Elect Form of Milestone Payment. NPS shall not be permitted to pay the Milestone Payment in the form of Milestone Shares, and must pay the Milestone Payment in cash (by means of a wire transfer of immediately available funds as contemplated by clause (x) of Section 7.2 above), in the event, and to the extent that the issuance and sale of the Milestone Shares to Takeda is subject to the (y) notification provisions of the HSR Act, and the waiting period applicable to the issuance and sale of the Milestone Shares under the HSR Act is not terminated within twenty (20) days of the date NPS or Takeda first submits notification of the transaction under the HSR Act to the appropriate governmental authorities; or (z) approval by the stockholders of NPS under any bylaw, listed securities maintenance standards or other rules of the Trading Market upon which the Milestone Shares would be listed (including, without limitation approval by the stockholders under NASDAQ Rule 5635). For clarity, NPS may make the Milestone Payment in a combination of cash and Milestone Shares in order to comply with this Section 7.3.

7.4 HSR or Other Regulatory Filings. In connection with the possible issuance of Milestone Shares pursuant to Section 7.2 hereof, to the extent required by applicable law after the occurrence of the Sales Milestone Date or a Qualifying Change of Control, NPS and Takeda shall, as promptly as reasonably practicable following NPS’s receipt of a request from Takeda, (i) make any required filing with the U.S. Federal Trade Commission (“FTC”), Department of Justice (“DOJ”) and any other governmental entity required under the HSR Act, or any other applicable law with respect to the issuance of such Milestone Shares, (ii) as promptly as practicable make or cause their Affiliates to make any filing or notice required under any other antitrust or competition law or other law or regulation agreed by the parties to be applicable to the issuance of such Milestone Shares and (iii) provide any supplemental information requested in connection with the HSR Act or such other antitrust, competition or other laws or regulations as promptly as practicable after such request is made.

THE SHARES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE PLEDGED, HYPOTHECATED, SOLD OR TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT FOR THE SHARES UNDER SUCH ACT OR AN OPINION OF COUNSEL TO THE ISSUER THAT REGISTRATION IS NOT REQUIRED UNDER THE ACT.

Lock-Up Legend

THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A LOCK-UP PERIOD OF UP TO 180 DAYS, AS SET FORTH IN AN AGREEMENT BETWEEN THE COMPANY AND THE ORIGINAL HOLDER OF THESE SHARES, A COPY OF WHICH MAY BE OBTAINED AT THE ISSUER’S PRINCIPAL OFFICE.

(b) Legend. Takeda acknowledges that, upon initial issuance, the certificates evidencing the Milestone Shares will bear the following legend:

Securities Act Legend

Certificates evidencing the Shares shall not be required to contain the legend (i) following any sale of such Shares pursuant to Rule 144 under the Securities Act, (ii) if such Shares are eligible for sale under Rule 144, or (iii) such legend is not required under applicable requirements of the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC), in the case of (ii) and (iii) to the extent reasonably determined by NPS’ legal counsel.

Certificates evidencing the Initial Consideration Shares shall not be required to contain the Lock-Up Legend following the expiration of the Initial Consideration Shares Lock-Up Period.

Takeda agrees that the removal of the restrictive legend(s) from certificates representing Shares as set forth in this Section is predicated upon NPS’ reliance that Takeda will sell any Shares pursuant to either the registration requirements of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom.

8.2 Registration of the Shares. The Shares have not been and are not being registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred except in compliance with the registration requirements of the Securities Act or an exemption therefrom.

8.3 No Integration. NPS agrees that it will not and will cause its Affiliates not to make any offer or sale of securities of NPS of any class if, as a result of the doctrine of “integration” referred to in Rule 502 under the Securities Act, such offer or sale would render invalid (for the purpose of the sale of any Shares (including Milestone Shares) by NPS to Takeda) the exemption from the registration requirements of the Securities Act provided by Section 4(2) thereof or otherwise.

8.4 Public Reporting. NPS agrees to: (a) make and keep current public information available, within the meaning of Rule 144 under the Securities Act or any similar or analogous rule promulgated under the Securities Act, at all times that it is subject to the reporting requirements of the Exchange Act; (b) file with the SEC, in a timely manner, all reports and other documents required under the Securities Act and Exchange Act (at all times that it is subject to such reporting requirements); and (c) so long as Takeda owns any Shares, then in connection with a sale of such Shares, furnish to

(a) any breach of any representation, warranty, covenant or agreement of Takeda contained in this Agreement;

(b) any Retained Liability;

(d) the gross negligence or willful misconduct of Takeda or its Affiliates in the performance of the Transition Services;

(e) the failure of NPS to withhold any taxes with respect to the issuance of the Shares or payment of the Milestone Payment in immediately available funds to Takeda hereunder.

11.2 Indemnification by NPS. NPS shall indemnify and defend Takeda and its Affiliates and their respective officers, directors, employees, agents, successors and assigns (the “Takeda Indemnitees”) against, and shall hold them harmless from, any and all Losses incurred by any Takeda Indemnitee, in each case resulting from, arising out of, or otherwise with respect to:

(a) any breach of any representation, warranty, covenant or agreement of NPS contained in this Agreement;

(b) any Assumed Liability;

(c) the ownership, operation or use of the Assets or the Products (including the development, commercialization and other exploitation thereof) on or after the Effective Date; and

(d) the performance by Takeda or its Affiliates of the Transition Services, except to the extent such Loss results from the gross negligence or willful misconduct of Takeda or its Affiliates.

11.3 Claim Procedures.

(a) Indemnification Claim Procedure. Except as provided in Section 11.3(b) with respect to Third Party claims, upon receipt by a Party obligated to provide indemnification under Section 11.1 or Section 11.2 of this Agreement, as applicable (each such Party, an “Indemnifying Party”), of a certificate (an “Indemnification Certificate”) signed by an NPS Indemnitee or a Takeda Indemnitee requesting indemnification as provided herein (the “Indemnified Party”): (i) stating that the Indemnified Party has paid or properly accrued or reasonably anticipates that it will have to pay or accrue Losses that are subject to indemnification by the Indemnifying Party pursuant to Section 11.1 or Section 11.2, as applicable, and (ii) specifying in reasonable detail the individual items and amounts of such Losses, the date each such item was paid or properly accrued, or the basis for such anticipated liability, and the nature of the misrepresentations, breach of warranty, covenant or agreement to which such item is related, the Indemnifying Party shall distribute to the Indemnified Party funds in an amount equal to such Losses within forty-five (45) days after delivery of the Indemnification Certificate; provided that no such payment or delivery shall be made if the Indemnifying Party shall object in a written statement to the claim made in the Indemnification Certificate and such statement shall have been delivered to the Indemnifying Party prior to the expiration of such forty-five- (45-) day period. An Indemnifying Party’s failure to object within such forty-five (45) day period to any claim set forth in an Indemnification Certificate shall be deemed to be the Indemnifying Party’s acceptance of, and waiver of any objections to, such claim. In case an Indemnifying Party shall so object in writing to any claim or claims made in any Indemnification

Certificate, the Indemnifying Party and the Indemnified Party shall attempt in good faith for a period of twenty (20) days following receipt of such objection notice to agree upon the rights of the respective parties with respect to each of such claims. If no such agreement can be reached after such twenty (20) day period of good faith negotiation, either the Indemnifying Party or the Indemnified Party may initiate litigation for purposes of having the matter settled in accordance with the terms of this Agreement.

(b) Third Party Claim Procedure. In the event an Indemnified Party becomes aware of a Third Party claim (including any action or proceeding commenced or threatened to be commenced by any Third Party) that such Indemnified Party reasonably believes may result in an indemnification pursuant to Section 11.1 or Section 11.2, as applicable, such Indemnified Party shall promptly (and in any event within three business days after becoming aware of such claim) notify the Indemnifying Party in writing of such claim (such notice, the “Claim Notice”). The Claim Notice shall be accompanied by reasonable supporting documentation submitted by the Third Party making such claim and shall describe in reasonable detail (to the extent known by the Indemnified Party) the facts constituting the basis for such claim and the amount of the claimed damages; provided that no delay or failure on the part of the Indemnified Party in delivering a Claim Notice shall relieve the Indemnifying Party from any liability hereunder except to the extent of any damage or liability caused by or arising out of such delay or failure. Within twenty (20) days after receipt of any Claim Notice, the Indemnifying Party may, upon written notice thereof to the Indemnified Party, assume control of the defense of the claim referred to therein at the Indemnifying Party’s sole cost and expense with counsel reasonably satisfactory to the Indemnified Party. If the Indemnifying Party does not so assume control of the defense of such claim, the Indemnified Party shall control the defense of such claim. The Party not controlling the defense of such claim (the “Non-controlling Party”) may participate therein at its own expense; provided that if the Indemnifying Party assumes control of the defense of such claim and the Indemnifying Party and the Indemnified Party have materially conflicting interests or different defenses available with respect to such claim that cause the Indemnified Party to hire its own separate counsel with respect to such suit proceeding, the reasonable fees and expenses of a single counsel to the Indemnified Party shall be considered “Losses” for purposes of this Agreement. The Party controlling the defense of such claim (the “Controlling Party”) shall keep the Non-controlling Party advised of the status of such claim 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 claim (including copies of any summons, complaint or other pleading that 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 claim. Neither the Indemnified Party nor the Indemnifying Party shall agree to any settlement of, or the entry of any judgment arising from, any such claim without the prior written consent of the other Party, which consent shall not be unreasonably withheld, conditioned or delayed; provided that the consent of the Indemnified Party shall not be required with respect to any such settlement or judgment if the Indemnifying Party agrees in writing to pay or cause to be paid any amounts payable pursuant to such settlement or judgment and such settlement or

judgment includes no admission of liability by or other obligation on the part of the Indemnified Party and includes a complete release of the Indemnified Party from further liability.

11.4 No Right of Offset. NPS shall have no right to offset against amounts otherwise owed by NPS to Takeda pursuant to Section 7.2 any amounts due to NPS or any NPS Indemnitees pursuant to Section 11.1.

11.5 Exclusive Remedy. Absent common law fraud or willful misconduct, (a) claims for indemnification pursuant to this Article 11, and (b) claims for specific performance pursuant to Section 14.13, shall, collectively, be the sole and exclusive remedies for claims and damages available to the Parties and their respective Affiliates arising out of or relating to this Agreement and the transactions contemplated hereby, including any breach by any Party of any representation, warranty or covenant contained in this Agreement.

11.6 Limitation of Liability. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, NEITHER NPS NOR TAKEDA SHALL BE LIABLE TO THE OTHER, OR THEIR AFFILIATES, FOR ANY CLAIMS, DEMANDS OR SUITS FOR CONSEQUENTIAL, INCIDENTAL, SPECIAL, EXEMPLARY, PUNITIVE, INDIRECT OR MULTIPLE DAMAGES, INCLUDING LOSS OF PROFITS, REVENUE OR INCOME, DIMINUTION IN VALUE OR LOSS OF BUSINESS OPPORTUNITY, WHETHER OR NOT FORESEEABLE CONNECTED WITH OR RESULTING FROM ANY BREACH OR ANY ACTIONS UNDERTAKEN IN CONNECTION WITH, OR RELATED HERETO, INCLUDING ANY SUCH DAMAGES WHICH ARE BASED UPON BREACH OF CONTRACT, TORT (INCLUDING NEGLIGENCE AND MISREPRESENTATION), BREACH OF WARRANTY, STRICT LIABILITY, STATUTE, OPERATION OF LAW OR ANY OTHER THEORY OF RECOVERY. THE LIMITATIONS OF LIABILITY SET FORTH IN THIS SECTION 11.6 SHALL NOT APPLY TO ANY SUCH DAMAGES THAT ARE REQUIRED TO BE PAID TO A THIRD PARTY AS PART OF A CLAIM FOR WHICH A PARTY PROVIDES INDEMNIFICATION UNDER THIS ARTICLE 11.

12. MUTUAL RELEASE

13.2 Termination.

(a) If either Party (the “Non-Breaching Party”) believes that the other Party (the “Breaching Party”) has materially breached one or more of its material obligations under this Agreement, then the Non-Breaching Party may deliver notice of such material breach to the Breaching Party (a “Default Notice”). The Parties agree that termination pursuant to this Section 13.2(a) is a remedy to be invoked only if the breach cannot be adequately remedied through a combination of specific performance and the payment of money damages. If the Breaching Party does not dispute that it has committed a material breach of one or more of its material obligations under this Agreement, then if the Breaching Party fails to cure such breach, or fails to take steps as would be considered reasonable to effectively cure such breach, within ninety (90) days after receipt of the Default Notice, the Non-Breaching Party may terminate this Agreement upon written notice to the Breaching Party. If the Breaching Party disputes that it has materially breached one of its material obligations under this Agreement, the dispute shall be resolved in accordance with Section 14.6. If the Breaching Party is determined to be in material breach of one or more of its material obligations under this Agreement (an “Adverse Ruling”), then if the Breaching Party fails to complete the actions specified by the Adverse Ruling to cure such material breach within ninety (90) days after such ruling, or if such compliance cannot be fully achieved within such ninety- (90-) day period and the Breaching Party has failed to commence compliance or has failed to use diligent efforts to achieve full compliance as soon thereafter as is reasonably possible, then the Non-Breaching Party may terminate this Agreement upon written notice to the Breaching Party.

(b) Either Party may terminate this Agreement immediately upon notice to the other Party if the other Party shall (i) file in any court or agency pursuant to any statute or regulation of any state, country or jurisdiction a petition in bankruptcy or insolvency or for reorganization or for arrangement or for the appointment of a receiver or trustee of that Party or its assets; (ii) propose a written agreement of composition or extension of all of its debts; (iii) be served with an involuntary petition against it, filed in any insolvency proceeding, and such petition shall not be dismissed within sixty (60) days after the filing thereof; (iv) propose or be a party to any dissolution or liquidation; (v) make an assignment for the benefit of its creditors; or (vi) admit in writing its inability generally to pay its debts as they become due in the general course;

13.3 Effects of Termination.

(a) The termination of this Agreement for any reason shall not release either Party from any liability or obligation that, at the time of such termination, has already accrued to such Party or that is attributable to a period prior to such termination, nor will any termination of this Agreement preclude either Party from pursuing all rights and remedies it may have under this Agreement, at law or in equity, with respect to breach of this Agreement.

(b) Upon expiration or termination of this Agreement, each Party shall promptly return to the other Party, or delete or destroy, all relevant records and materials in such Party’s possession or control containing Confidential Information of the other Party; provided that such Party may keep one copy of such materials for archival purposes only subject to a continuing confidentiality obligations.

(c) Upon the expiration or earlier termination of this Agreement, the following Articles and Sections shall survive: Sections 3.2, 3.6, 3.7, 3.8, 3.9, 8.3, 10.5, and 13.3, and Articles 5, 9, 11, 12 and 14.

This Agreement may not be modified, amended, altered or supplemented except upon the execution and delivery of a written agreement executed by both Parties hereto.

14.4 Force Majeure. Neither Party shall be liable for damages or be deemed to have defaulted under or breached this Agreement, nor shall this Agreement be terminable or cancelable, by reason of any delay or failure in such Party’s performance hereunder if such failure or delay is caused by acts of God, war or insurrection, civil commotion, earthquake, fire, flood, storm or epidemic or other cause out of such Party’s reasonable control (“Force Majeure”).

14.9 Severability. If any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, the Parties shall substitute by mutual consent a valid provision for such illegal, unenforceable or void provision, which valid provision in its economic effect is sufficiently similar to the illegal, unenforceable or void provision that it can be reasonably assumed that the Parties would have entered into this Agreement with such valid provision. If such valid provision cannot be agreed on, then this Agreement shall continue in full force and effect without such illegal, unenforceable or void provision, so long as this Agreement, taking into account such provision, continues to provide the Parties with materially the same benefits as set forth in this Agreement containing such provision on the Effective Date.

14.10 Waiver. No waiver, modification or amendment of any provision of this Agreement shall be valid or effective unless made in writing and signed by a duly authorized officer of each Party.
