8.4 Development Milestone Payments. Subject to the remainder of this Section 8.4, Sana shall pay to Beam the milestone payments set forth in the “Milestone Payment A” column of the table below (each, a “Development Milestone Event”) upon the achievement of such Development Milestone Event by a Licensed Product being Developed or Commercialized by or on behalf of Sana or any of its Affiliates or Sublicensees, provided, however, that that in the event that [***], Sana shall, in lieu of the amount set forth in the “Milestone Payment A” column in the table below, instead pay to Beam the applicable milestone payment set forth in the “Milestone Payment B” column of the table below.

Development Milestone Event	Milestone Payment A	Milestone Payment B
1. [***]	[***]	[***]
2. [***]	[***]	[***]

8. [***]	[***]	[***]

(a) Each development milestone payment in this Section 8.4 will be non-refundable, non-creditable, and (i) will be payable only once for each Licensed Product, regardless

26

ACTIVEUS 188080012v.21

of the number of times that such milestone event is achieved by such Licensed Product, and (ii) will not be payable (A) with respect to a subsequent achievement of the same Development Milestone Event by a Licensed Product that is a replacement for another Licensed Product, the development of which has been discontinued after achievement of such same Development Milestone Event, (B) with respect to a subsequent achievement of the same Development Milestone Event by any back-up Licensed Product that is a Related Product to a first Licensed Product that has already achieved such same Development Milestone Event, or (C) with respect to a subsequent achievement of the same Development Milestone Event by a Licensed Product that differs from a first Licensed Product that has achieved such same Milestone Event only by virtue of such subsequent Licensed Product’s being a different dosage strength or formulation of or using a different delivery system than such first Licensed Product.

(b) The milestones set forth in this Section 8.4 are intended to be successive. If a Licensed Product is not required to undergo the event associated with a particular Development Milestone Event for a given Licensed Product (a “Skipped Milestone”), such Skipped Milestone will be deemed to have been achieved upon the achievement by such Licensed Product of the next successive Development Milestone Event (“Achieved Milestone”). Payment for any Skipped Milestone that is owed in accordance with the provisions of Section 8.4 shall be due within [***] days after Sana learned of the achievement of the Achieved Milestone. For clarity, [***] in a jurisdiction shall not trigger payment of another [***] milestone not yet achieved (for example, [***] shall not trigger a payment obligation for [***], nor vice versa). Additionally, in the event that Sana [***] in the table above in this Section 8.4 [***], the applicable Development Milestone Event 7 or 8 shall be deemed achieved, and the applicable payment will then be due in accordance with this Section 8.4.

(c) Sana will notify Beam within [***] days after achievement (or deemed achievement) of each Development Milestone Event. Sana will pay to Beam the corresponding milestone payment set forth in the table above within [***] days after achievement of each Development Milestone Event.

ACTIVEUS 188080012v.21

(a) Each sales milestone payment in this Section 8.5 will be non-refundable, non-creditable and (i) will be payable only once for each Licensed Product, regardless of the number of times that such Commercial Milestone Event is achieved by such Licensed Product, and (ii) will not be payable (A) with respect to a subsequent achievement of the same Commercial Milestone Event by a Licensed Product that is a replacement for another Licensed Product, the commercialization of which has been discontinued after achievement of such same Milestone Event; (B) with respect to a subsequent achievement of the same Commercial Milestone Event by any back-up Licensed Product that is a Related Product to a first Licensed Product that has already achieved such same Commercial Milestone Event; and (C) with respect to a subsequent achievement of the same Commercial Milestone Event by a Licensed Product that differs from a first Licensed Product that has achieved such same Commercial Milestone Event only by virtue of such subsequent Licensed Product’s being a different dosage strength or formulation of or using a different delivery system than such first Licensed Product. For clarity, regardless of the number of Licensed Products that achieve any Commercial Milestone Event, in no event shall Sana pay Beam pursuant to this Section 8.5 more than $[***] with respect to each Licensed Product.

(b) The milestone payments in this Section 8.5 shall be additive, such that if more than one Commercial Milestone Event specified above is achieved in the same Calendar Year, then the milestone payments for all such milestone events so achieved shall be payable in the same Calendar Year in accordance with Section 8.5(c).

(c) As part of the Calendar Quarterly royalty report in Section 8.7(d), Sana shall notify Beam if the aggregate annual Net Sales of any Licensed Product first reached a value set forth above during the Calendar Quarter to which such report pertains. Sana shall pay to Beam the applicable sales milestone payments within [***] days after the conclusion of the Calendar Quarter in which the applicable Commercial Milestone Event is achieved.

8.6 [***] Agreement Milestones. Notwithstanding anything to the contrary in Section 8.4 or 8.5, if: (a) (i) any event occurs with respect to a Licensed Product or any Enabled Product (as such term is defined in the [***] Agreement) developed or commercialized by Sana (or its Affiliates or Sublicensees) triggers a milestone payment by Beam pursuant to the [***] Agreement, and (ii) no milestone payment is owed by Sana to Beam under this Agreement or the amount of the milestone payment owed under this Agreement is less than the amount of the milestone payment owed by Beam under the [***] Agreement (including as a result of Section 4.5 of the [***] Agreement with respect to activities of Sana, its Affiliates and its Sublicensees); then (b) Sana will provide written notice to Beam and pay the amount of such milestone (or gross up its payment to Beam such that the amount of the milestone paid by Sana is not less than that owed by Beam under the [***] Agreement) to Beam within [***] days after receipt of Beam’s invoice therefor.

8.7 Royalty Payments.

(a) Pass Through Royalty Payments. Sana shall pay Beam pass-through royalty payments equal to the royalty payments owed by Beam pursuant to the [***] Agreement

28

ACTIVEUS 188080012v.21

as a direct result of the Net Sales of each Licensed Product sold by Sana, its Affiliates or Sublicensees that is a Licensed Product or Enabled Product (as defined in the [***] Agreement) for the duration of the Royalty Term (as such term is defined in the [***] Agreement and as used herein, the “[***] Royalty Term”) in accordance with the terms set forth on Exhibit F.

(b) Royalty Rates. Subject to the remainder of this Section 8.7, in addition to the payments set forth in Section 8.7(a), Sana shall pay Beam [***] of all Net Sales of each Licensed Product sold by Sana, its Affiliates or Sublicensees during the Royalty Term.

(c) Royalty Term. Sana’s royalty payment obligations under Section 8.7(b) shall, on a Licensed Product-by- Licensed Product and country-by-country basis, commence on the Effective Date and expire upon the latest of: (i) the expiration of the last to expire Valid Claim within the Beam Patents that Covers such Licensed Product (or if the last Covering Valid Claim with respect to such Licensed Product in such country is a pending Valid Claim, the date such pending Valid Claim ceases to be a Valid Claim; provided, however, that subsequent issuance of such Valid Claim shall again extend the Royalty Term from the date of such issuance to the expiration date of such Valid Claim); (ii) the expiration of all applicable Regulatory Exclusivity, if any, for such Licensed Product in such country; and (iii) ten (10) years after the First Commercial Sale of such Licensed Product in such country (the “Royalty Term”). Upon expiration of a Royalty Term for a Licensed Product in a given country, no further royalty payments will be owed for such Licensed Product in such country pursuant to Section 8.7(b) and the licenses granted to Sana in Section 2.1(b) will automatically become fully paid-up, perpetual and irrevocable with respect to such Licensed Product in such country. Upon expiration of both (A) the Royalty Term for a Licensed Product in a given country and (B) expiration of the [***] Royalty Term for such Licensed Product in such country, the license granted to Sana in Section 2.1(b) will automatically become fully paid-up, perpetual, irrevocable, and royalty-free with respect to such Licensed Product in such country.

(d) Reports and Payment. Within [***] days after the end of each Calendar Quarter during the applicable Royalty Term, Sana shall provide Beam with a good faith written estimate of the following information for the applicable Calendar Quarter, on a Licensed Product-by-Licensed Product and country-by-country basis: (A) the amount of gross sales of the each Licensed Product, (B) the number of units of Licensed Products sold, leased or otherwise transferred for the applicable Calendar Quarter; (C) an itemized calculation of Net Sales showing deductions provided for in the definition of “Net Sales,” (D) a calculation of the royalty due on such sales, (E) the exchange rate for such country, and (F) whether any sales milestone event has been achieved during such Calendar Quarter (collectively, the “Royalty Information”). Within [***] days after the end of each Calendar Quarter during the applicable Royalty Term, Sana shall provide Beam updated, finalized Royalty Information and pay in Dollars all royalty payments due to Beam for such Calendar Quarter.

8.8 Payments for Third Party IP Rights. Except as expressly set forth in Section 8.7(a), Beam shall remain responsible for all obligations to and payments of royalty, milestone and other payments under Existing Third Party Licenses. To the extent that Beam obtains a license to any Third Party intellectual property rights other than those for which Beam is responsible in this

29

ACTIVEUS 188080012v.21

Section 8.8, and Sana elects to receive a sublicense under such Third Party intellectual property rights pursuant to Section 2.4(b) (thus causing the applicable license agreement to be a Third Party License), Sana shall pay to Beam the applicable portion of any additional payments due arising from Sana’s exercise of such Third Party License as provided in Section 2.4(b) in a timely manner, such that Beam may pay such amounts to the applicable Third Party on or before the applicable due date.

8.9 Currency; Exchange Rate. All payments to be made by Sana to Beam under this Agreement shall be computed and paid in Dollars by bank wire transfer in immediately available funds to the bank account set forth on Exhibit G, in accordance with the instructions therein. With respect to sales of a Licensed Product and other amounts received that are invoiced in a currency other than U.S. dollars, such amounts and amounts payable will be converted to U.S. dollars using the exchange rate mechanism generally applied by Sana or its Affiliates in preparing its financial statements for the applicable Calendar Quarter, provided that such mechanism is in compliance with GAAP.

8.10 Late Payments. If Beam does not receive payment of any undisputed sum due to it on or before the due date therefor, simple interest shall thereafter accrue on the sum due from the due date until the date of payment at a monthly rate of [***] or the maximum rate allowable by applicable Law, whichever is less.

8.11 Withholding Taxes.

(a) Taxes on Income. Each Party shall be solely responsible for the payment of all taxes imposed on its share of income arising directly or indirectly from the activities of the Parties under this Agreement.

(b) Tax Cooperation. The Parties agree to cooperate with one another and use reasonable efforts to avoid or reduce tax withholding or similar obligations in respect of the milestone payments, royalties and other payments made by Sana to Beam under this Agreement, it being understood and agreed that based on the payment obligations hereunder as of the Effective Date (U.S. party Sana to U.S. party Beam), that no withholding tax is due or applicable to any payment absent Beam’s failure to provide a properly executed IRS Form W-9. As such, the sum payable by Sana (in respect of which any deduction or withholding tax may be required to be made, if any) shall, in the case of any withholding tax or similar reduction, be increased to the extent necessary to ensure that Beam receives a sum equal to the sum which it would have received had no such withholding tax applied. To the extent, however, Beam assigns or restructures its rights under the Agreement, including any assignment, sublicense, change of place of incorporation (“Beam Withholding Tax Action”), such that a foreign Affiliate or non-U.S. domiciled Beam is entitled to payments hereunder, and as a result thereafter Sana is required to deduct and withhold any additional taxes on any payment to Beam or such Beam Affiliate than previously due, Sana shall pay the amounts of such taxes to the proper Governmental Authority in a timely manner and promptly transmit to Beam an official tax certificate or other evidence of the additional amount of taxes resulting from such Beam Withholding Tax Action with such payment sufficient to enable Beam or such Beam Affiliate to claim such payment of taxes. (By way of example, if the withholding tax rate for which Sana is grossing up its payments to Beam under this

30

ACTIVEUS 188080012v.21

Section 8.11(b) is 15%, and as a result of a Beam Withholding Tax Action the withholding tax rate increases to 20%, then Sana shall continue to gross up Beam for the 15%, but Beam shall cover the economic expense of the additional 5% withholding tax increase caused by the Beam Withholding Tax Action). Such Beam affiliate or Beam shall provide Sana any tax forms that may be reasonably necessary in order for Sana to not withhold tax or to withhold tax at a reduced rate under an applicable bilateral income tax treaty, to the extent legally able to do so. Beam shall use reasonable efforts to provide any such tax forms to Sana in advance of the due date. Each Party shall also provide the other Party with reasonable assistance to enable the recovery, as permitted by Law, of withholding taxes or similar obligations resulting from payments made under this Agreement, such recovery to be for the benefit of Beam.

(c) Taxes Resulting from Sana’s Action. If a withholding or deduction obligation arises as a result of any action by Sana, including any assignment, sublicense, change of place of incorporation, or failure to comply with applicable Laws or filing or record retention requirements (an “Sana Withholding Tax Action”), then the sum payable by Sana (in respect of which such deduction or withholding is required to be made) shall be increased to the extent necessary to ensure that Beam receives a sum equal to the sum which it would have received had no such Sana Withholding Tax Action occurred.

8.12 Records and Audit Rights. Sana shall, and shall cause its Affiliates and Sublicensees to, maintain complete and accurate records in sufficient detail to permit Beam to confirm the accuracy of the amount of research and other costs to be reimbursed, achievement of milestones, royalties and other amounts payable under this Agreement for the then current Calendar Year, and during the preceding [***] Calendar Years. Upon reasonable prior notice, which shall be no less than upon [***] days prior written notice, such records shall be open during regular business hours for a period of [***] years from the creation of individual records for examination by an independent certified public accountant selected by Beam and reasonably acceptable to Sana for the sole purpose of verifying for Beam the basis and accuracy of the financial reports furnished by Sana pursuant to this Agreement or of any payments made, or required to be made, by or to the audited party pursuant to this Agreement; provided however, that records for a particular period may only be audited [***]. Such audits may occur no more often than [***] each Calendar Year. Such auditor shall enter into a confidentiality agreement between the auditor and Beam and not disclose the audited party’s Confidential Information to Beam. Any undisputed amounts shown to be owed but unpaid, or overpaid and in need of refund, shall be paid or refunded (as the case may be) within [***] days after the accountant’s report, plus interest (as set forth in Section 8.10) from the original due date. Beam shall bear the full cost of such audit unless such audit reveals an underpayment by more than [***] of the amount due for the entire period being audited, in which case Sana shall reimburse Beam for the reasonable costs for such audit.

8.13 Payments. Notwithstanding the non-refundable or non-creditable nature of any payments hereunder, and except as provided under Section 14.6, nothing in this Agreement shall limit Sana’s or its Affiliate’s rights to assert or obtain damages for breach of this Agreement, including seeking recoupment from any such payments made.

Unless otherwise set forth herein, the Enforcing Party shall have the right to settle such claim; provided that neither Party shall have the right to settle any Relevant Enforcement Action in a manner that materially diminishes or has a material adverse effect on the rights or interest of the other Party, or in a manner that imposes any costs or liability on, or involves any admission by, the other Party, without the express written consent of such other Party. To the extent that a Party is joined to any Relevant Enforcement Action, the Enforcing Party shall provide the joined Party with copies of all pleadings and other documents filed with the court and shall consider reasonable input from the joined Party during the course of the proceedings.

(c) Recovery. Any recovery realized as a result of a Relevant Enforcement Action (whether by way of settlement or otherwise) shall be first allocated to reimburse the Parties for their costs and expenses in making such recovery (which amounts shall be allocated pro rata if insufficient to cover the totality of such expenses).

Article 11 TERM AND TERMINATION

11.1 Term. The term of this Agreement shall commence upon the Effective Date and continue in full force and effect, on a Licensed Product-by-Licensed Product and country-by-country basis, until such time as both the Royalty Term and the [***] Royalty Term with respect to such Licensed Product expires in such country (the “Term”). Upon expiration of the Term in its entirety, the license granted to Sana in Section 2.1(b) will, to the extent not already provided for under Section 8.7(c), automatically become fully paid-up, perpetual and irrevocable with respect to all Licensed Products in the Territory.

If either Party is seeking indemnification under Section 13.1 or Section 13.2 (the “Indemnified Party”), it shall inform the other Party (the “Indemnifying Party”) of the claim giving rise to the obligation to indemnify pursuant to such Section as soon as reasonably practicable after receiving notice of the claim provided, however, that no delay on the part of the Indemnified Party in notifying the Indemnifying Party will relieve the Indemnifying Party from any obligation hereunder unless (and then only to the extent that) the Indemnifying Party is prejudiced thereby.

ACTIVEUS 188080012v.21

(b) Control. The Indemnifying Party shall have the right, exercisable by notice to the Indemnified Party within [***] days after receipt of notice from the Indemnified Party of the commencement of or assertion of any Third Party Claim, to assume the direction and control of the defense, litigation, settlement, appeal or other disposition of any such claim for which it is obligated to indemnify the Indemnified Party (including the right to settle the claim solely for monetary consideration) with counsel selected by the Indemnifying Party and reasonably acceptable to the Indemnified Party. During such time as the Indemnifying Party is controlling the defense of such Third Party Claim, the Indemnified Party shall reasonably cooperate with the Indemnifying Party in such defense at the Indemnifying Party’s request and expense. If the Indemnifying Party does not notify the Indemnified Party of the Indemnifying Party’s intent to defend any Third Party Claim within [***] days after notice thereof, the Indemnified Party may (with notice to the Indemnifying Party) undertake the defense thereof with counsel of its choice and at the Indemnifying Party’s expense (including reasonable, out-of-pocket attorneys’ fees and costs and expenses of enforcement or defense). The Indemnifying Party or the Indemnified Party, as the case may be, shall have the right to participate (including the right to conduct discovery, interview and examine witnesses and participate in all settlement conferences), but not control, at its own expense and with counsel of its choice, in the defense of any claim that has been assumed by the other Party.

(c) Settlement. Neither Party shall have the obligation to indemnify the other Party in connection with any settlement made without the Indemnifying Party’s written consent, which consent shall not be unreasonably withheld or delayed.

(d) Upstream Indemnification. Any claim for indemnification that arises in connection with Section 13.3 shall be governed by Section 9.1.2 of the [***] Agreement.

13.5 Mitigation of Loss. Each Indemnified Party shall take and shall procure that its Affiliates take all such reasonable steps and action as are reasonably necessary or as the Indemnifying Party may reasonably require in order to mitigate any claims (or potential losses or damages) under this Article 13. Nothing in this Agreement shall or shall be deemed to relieve any Party of any common law or other duty to mitigate any losses incurred by it.

13.6 Insurance.

(a) Beginning at the time any Licensed Product is being commercially distributed or sold (other than for the purpose of obtaining Marketing Approvals) by Sana, or by an Affiliate, Sublicensee or agent of Sana, Sana shall, at its sole cost and expense, procure and maintain commercial general liability insurance in amounts not less than $[***] per incident and $[***] annual aggregate and naming the Indemnitees as additional insureds. During Clinical Studies (as defined in the [***] Agreement) of any such Licensed Product Sana shall, at its sole cost and expense, procure and maintain commercial general liability insurance in such equal or lesser amount as Beam, [***] or any other Institution (as defined in the [***] Agreement) shall require, naming the [***] Indemnitees as additional insureds. Such commercial general liability insurance shall provide: (i) product liability coverage and (ii) broad form contractual liability coverage for Sana’s indemnification obligations under this Agreement.

47

ACTIVEUS 188080012v.21

(b) If Sana elects to self-insure all or part of the limits described above in Section 13.6(a) (including deductibles or retentions that are in excess of $[***] annual aggregate) such self-insurance program must be acceptable to Beam, [***] and the other Institutions and Federal Insurance Company (([***]’s insurer) in their sole discretion. The minimum amounts of insurance coverage required shall not be construed to create a limit of Sana’s liability with respect to its indemnification obligations under this Agreement.

(c) Sana shall provide each Beam and Institution with written evidence of such insurance upon request of Beam or such Institution. Sana shall provide Beam and each Institution with written notice at least thirty (30) days prior to the cancellation, non-renewal or material change in such insurance. If Sana does not obtain replacement insurance providing comparable coverage within such thirty (30) day period, Beam shall have the right to terminate this Agreement effective at the end of such [***] day period without notice or any additional waiting periods.

(d) Sana shall maintain such commercial general liability insurance beyond the expiration or termination of this Agreement during: (a) the period that any Licensed Product is being commercially distributed or sold by Sana, or an Affiliate, Sublicensee or agent of Sana; and (b) a reasonable period after the period referred to in (a) above which in no event shall be less than [***] years.

13.7 Limitation of Liability. NEITHER PARTY SHALL BE LIABLE TO THE OTHER FOR ANY SPECIAL, CONSEQUENTIAL, INCIDENTAL, PUNITIVE, OR INDIRECT DAMAGES ARISING FROM OR RELATING TO ANY BREACH OF THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF THE POSSIBILITY OF SUCH DAMAGES. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 13.7 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE (A) INDEMNIFICATION RIGHTS OR OBLIGATIONS OF ANY PARTY UNDER SECTION 13.1, 13.2 OR 13.3, OR (B) DAMAGES AVAILABLE FOR A PARTY’S BREACH OF ITS CONFIDENTIALITY OBLIGATIONS IN Article 10 OR USE OF bEAM TECHNOLOGY IN A MANNER OTHER THAN AS EXPRESSLY PERMITTED UNDER SECTION 2.1; or (C) DAMAGES AVAILABLE FOR A PARTY’S GROSS NEGLIGENCE, INTENTIONAL MISCONDUCT OR FRAUD.

Article 14 GENERAL PROVISIONS

14.1 Force Majeure. Neither Party shall be held liable to the other Party nor be deemed to have defaulted under or breached this Agreement for failure or delay in performing any obligation under this Agreement to the extent such failure or delay is caused by or results from causes beyond the reasonable control of the affected Party, potentially including embargoes, war, acts of war (whether war be declared or not), acts of terrorism, epidemics, pandemics, insurrections, riots, civil commotions, strikes, lockouts or other labor disturbances, fire, floods, earthquakes or other acts of God, or acts, generally applicable action or inaction by any governmental authority (but excluding any government action or inaction that is specific to such Party, its Affiliates or sublicensees, such as revocation or non-renewal of such Party’s license to conduct business), or omissions or delays in acting by the other Party, or unavailability of materials

48

ACTIVEUS 188080012v.21

related to the manufacture of the Licensed Products or components thereof. The affected Party shall notify the other Party in writing of such force majeure circumstances as soon as reasonably practical, and shall promptly undertake and continue to use Commercially Reasonable Efforts to cure such force majeure circumstances or to perform its obligations in spite of the ongoing circumstances.

14.2 Non-Solicitation. During the Term, each Party agrees that neither it nor any of its Affiliates will recruit, solicit, or induce any employee of the other Party that such Party knew [***] to terminate his or her employment with such other Party and become employed by or consult for such Party, whether or not such employee is a full-time employee of such other Party, and whether or not such employment is pursuant to a written agreement or is at-will. For purposes of the foregoing, “recruit,” “solicit,” or “induce” will not be deemed to mean (a) circumstances where an employee of a Party (such employee, a “Soliciting Employee,” and such Party, the “Existing Employer”) (i) initiates contact with the other Party (the “Prospective Employer”) or any of its Affiliates with regard to possible employment; or (ii) responds to general solicitations of employment not specifically targeted at employees of the Existing Employer or any of its Affiliates, including responses to general advertisements or postings (each of (i) and (ii), an “Employee-Initiated Solicitation”), and (b) discussions, interviews, negotiations, offers, or acceptances of employment or similar activities that arise as a result of circumstances described in the foregoing clause (a).

14.3 Assignment. This Agreement may not be assigned or otherwise transferred, nor may any right or obligation hereunder be assigned or transferred, by either Party without the prior written consent of the other Party, and in the case of Sana, without the prior written consent of the [***]. Notwithstanding the foregoing, either Party may, without consent of the other Party (or the [***], in the case of assignment by Sana), assign or transfer this Agreement and its rights and obligations hereunder in whole or in part to an Affiliate of such Party, or in whole to its successor in interest in connection with the sale of all or substantially all of its stock or its assets to which this Agreement relates, or in connection with a merger, acquisition or similar transaction of the assigning Party, as long as such successor in interest agrees in writing to assume all of the assigning Party’s obligations under this Agreement. In addition, either Party may, with the consent of the other Party (which shall not be unreasonably withheld), assign or transfer its rights and obligations under this Agreement to a Third Party (so long as such Third Party is not a direct competitor of the other Party) where such assigning Party or its Affiliate is required, or makes a good faith determination based on advice of counsel, to divest its rights in connection with a Licensed Product in order to comply with Law or the order of any Governmental Authority as a result of a merger or acquisition or similar transaction of the assigning Party, as long as such Third Party agrees in writing to assume all of the assigning Party’s obligations under this Agreement. Any attempted assignment not in accordance with this Section 14.3 shall be null and void and of no legal effect. Any permitted assignee shall assume in writing all assigned obligations of its assignor under this Agreement. The terms and conditions of this Agreement shall be binding upon, and shall inure to the benefit of, the Parties and their respected successors and permitted assigns. In the event of any assignment by a Party of this Agreement, such Party shall remain primarily liable to the other Party for the performance of this Agreement.

14.4 Severability. If any one or more of the provisions contained in this Agreement is held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein shall not in any way be affected or impaired thereby, unless the absence of the invalidated provision(s) adversely affects the substantive rights of the Parties.
