holder is not entitled to the relief provided by Section 1705.41 of the Ohio Act, such Membership Interests shall be treated as
if they had been converted as of the Effective Time into the right to receive the Portion of the Merger Consideration, if any,
to which such holder is entitled pursuant to Section 2.07(a), without interest thereon. The Company shall provide Parent
prompt written notice of any demands received by the Company for dissenters rights, any withdrawal of any such demand and any other

and retired and shall cease to exist, and, subject to Section 2.08, each holder of Membership Interests shall cease to have
any rights as a Member of the Company.



(b)          Parent
shall be appointed as of the Effective Time (the “Exchange Agent”) to act as the exchange agent in the Merger.

each Member shall deliver to the Exchange Agent a duly completed and validly executed letter of transmittal substantially in the
form of Exhibit B hereto (the “Letter of Transmittal”), together with written instructions regarding
(i) the Person in whose name the Portion of the Closing Merger Consideration issuable to such holder shall be registered, and (ii)
the Person to whom the certificate(s) representing such Parent Common Stock shall be delivered at Closing (collectively, subclauses
(i) and (ii), the “Instructions”). Until such Letter of Transmittal is delivered, the Membership Interests shall
be deemed from and after the Effective Time, for all purposes, to evidence the right to receive the Portion of the Merger Consideration
as provided in Section 2.07(a).



(d)          The
Exchange Agent shall as soon as practicable following the Effective Time, subject to the Exchange Agent’s receipt of such
Member’s delivery of a Letter of Transmittal and Instructions, issue and deliver to such Member the certificate(s) representing
such Member’s Portion of the Closing Merger Consideration in accordance with such Instructions.



(e)          If
any portion of the Closing Merger Consideration is to be paid to a Person other than the Person in whose name the Membership Interest
is registered, it shall be a condition to such payment that (i) the Exchange Agent be provided with reasonable evidence of the
transfer of such Membership Interest to such Person, and (ii) the Person requesting such payment shall pay to the Exchange Agent

Interest or establish to the reasonable satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

Further Ownership Rights in Company Membership Interests. All Merger Consideration paid or payable upon the delivery of a Letter
of Transmittal in accordance with the terms hereof shall be deemed to have been paid or payable in full satisfaction of all rights
pertaining to the Membership Interests, and from and after the Effective Time, there shall be no further registration of transfers
of Membership Interests on the transfer books of the Surviving Entity. If, after the Effective Time, Letters of Transmittal with
regard to Membership Interests which have not been surrendered in accordance with Section 2.09 are presented to the Surviving
Entity, the Membership Interests so surrendered shall be cancelled and exchanged for the Merger Consideration provided for, and
in accordance with the procedures set forth, in this ARTICLE II and elsewhere in this Agreement.



16







Section 2.11.   Adjustments.
Without limiting the other provisions of this Agreement, if at any time during the period between the date of this Agreement and
the Effective Time, any change in the outstanding shares of capital stock of Parent shall occur, including by reason of any reclassification,
recapitalization, stock split (including reverse stock split) or combination, exchange or readjustment of shares, or any stock
dividend or distribution paid in stock, the Merger Consideration and any other amounts payable pursuant to this Agreement shall
be appropriately adjusted to reflect such change. For the avoidance of doubt, issuances of Parent Common Stock will have no effect
or adjustment to the Merger Consideration set forth in this Section 2.11.



Section 2.12.   Withholding

the consideration otherwise payable to any Person pursuant to this ARTICLE II such amounts as may be required to be deducted
and withheld with respect to the making of such payment under any provision of Tax Law. To the extent that amounts are so deducted
and withheld by the Exchange Agent, Parent, Merger Sub or the Surviving Entity, as the case may be, such amounts shall be treated
for all purposes of this Agreement as having been paid to the Person in respect of which the Exchange Agent, Parent, Merger Sub
or the Surviving Entity, as the case may be, made such deduction and withholding.



Section 2.13.   Intentionally
Omitted.



Section 2.14.   Holdback
Amount. At the Closing, Parent shall retain the Holdback Amount solely to satisfy any reduction in the Merger Consideration
to which Parent is entitled pursuant to the provisions of ArticleVIII,
or any other provision of this Agreement. Subject to such provisions, Parent shall pay the Holdback Amount as follows:



(a)          Payments.
Within ten (10) Business Days following the Holdback Amount Payment Date, Parent shall pay, deliver, or cause to be paid or delivered,
to the Members the remaining Holdback Amount, if any, minus any portion thereof which Parent is directed or entitled to
retain pursuant to ArticleVIII, or any other provision of this Agreement
for amounts owed to Parent, by (i) paying to each Member its Portion of the remaining cash portion of the Holdback Amount, if any,
and (ii) issuing to each Member a certificate evidencing such Member’s Portion of the remaining Parent Common Stock portion
of the Holdback Amount, if any, in each case as set forth in Consideration Spreadsheet.



(b)          Letter
of Transmittal. Only Members who have properly delivered a duly completed and validly executed Letter of Transmittal as set
forth in Section 2.09(c) shall be entitled to receive any payment of the Holdback Amount, if any, payable pursuant to this
Agreement.



17







Section 2.15.  Milestones.
Subject to the terms and conditions of this Agreement, Parent shall pay to the Members the Milestone Payments (if any) as follows:



(a)          Milestone
Payments. If Parent determines pursuant to Section 2.15(b) that a Milestone has been Satisfied on or prior to the Milestone
Deadline Date applicable to such Milestone, Parent shall pay or cause to be paid to the Members the applicable Milestone Payments
within ten (10) Business Days of the applicable Satisfaction Date with respect to such Milestone as set forth on Annex A,
by delivering to each Member its Adjusted Pro Rata Interest of such Milestone Payment.



(b)          Satisfaction
of Milestones. Parent, using its reasonable and good faith discretion, shall determine whether or not each Milestone has been
fully satisfied (“Satisfied” or “Satisfaction”) and the date upon which such Satisfaction
occurs (with respect to each Milestone, the “Satisfaction Date”). Parent shall consult in good faith with Member
Representative when determining whether or not each Milestone has been Satisfied. This Section 2.15 shall not impose or
imply any restriction or limitation on Parent’s right to conduct its business in its sole and absolute discretion. The Parent,
itself or through one or more of its Affiliates, will use Commercially Reasonable Efforts to achieve each of the Milestones. For
purposes of this Section 2.15(b), “Commercially Reasonable Efforts” means with respect to the efforts
to be expended by Parent and its Affiliates with respect to the Milestones, reasonable, diligent, good faith efforts to accomplish
any such Milestones as is commonly used in the biotechnology industry generally to accomplish a similar objective under similar
circumstances by companies of similar size with similar resources as Parent, and such efforts will be substantially equivalent
to those efforts and resources commonly used in the biotechnology industry generally by a biotechnology company for a product owned
by it or to which it has rights, that is at a similar stage in its development and is of similar market potential as MPS-IIIA or
MPS-IIIB taking into account efficacy, safety, approved labeling, the competitiveness of alternative products in the marketplace,
the patent and other proprietary position of the product, the likelihood of regulatory approval, the profitability and commercial
potential of the product, but without regard to any Milestone Payment due to be paid to the Members hereunder.



(c)          Milestone
Satisfaction Dispute Resolution. In the event that Parent determines that a Milestone has not been Satisfied on or before the
applicable Milestone Deadline Date, Parent shall deliver to Member Representative written notice of such failure to achieve the
applicable Milestones setting forth in reasonable detail the basis for such determination (the “Milestone Failure Notice”)
no later than ten (10) Business Days following the applicable Milestone Deadline Date. If Member Representative disagrees with
Parent’s determination as set forth in the Milestone Failure Notice, Member Representative shall notify Parent in writing
in detail of its disagreement and the basis therefor within ten (10) Business Days after receipt of such determination (the “Member
Representative Objection”). If Member Representative Objection is not received by Parent within such ten (10) Business
Day period, Parent’s determination shall be deemed final and binding for all purposes of this Agreement. If Parent does receive
the Member Representative Objection within such ten (10) Business Day period, Parent and Member Representative shall attempt in
good faith to resolve any disagreement for a period of thirty (30) days after Parent’s receipt of the Member Representative
Objection. If Parent and Member Representative resolve their disagreement they shall set forth the agreement in a written document
executed by Parent and Member Representative and such written document shall be deemed final and binding for all purposes of this
Agreement. If Parent and Member Representative are unable to resolve their disagreement within such thirty (30) day period, the
parties shall submit such dispute to binding arbitration in Washington, D.C. before a single arbitrator, who shall have significant
experience in biopharmaceutical clinical development disputes. The arbitration shall be administered by JAMS pursuant to its Comprehensive
Arbitration Rules and Procedures. Judgment on the award may be entered in any court having jurisdiction. The costs of arbitration,
including the fees of the arbitrator, shall be born equally one-half by Parent and one-half by the Members. Notwithstanding the
foregoing, the arbitrator may, in the award, allocate all or a portion of the costs of the arbitration, including the fees of the
arbitrator and the reasonable attorneys’ fees of the other party.



18







(d)          Form
of Milestone Payment. Parent may pay each Milestone Payment in cash, shares of Parent Common Stock or a combination thereof,
in its sole discretion, subject in all cases to Stockholder Approval (for the avoidance of doubt, such Stockholder Approval shall
not include the shares of Parent Common Stock held by the Members) to approve such issuance in Parent Common Stock. Shares of Parent
Common Stock included in a Milestone Payment shall be valued at the Parent Share Value.



(e)          Tax
Treatment of Contingent Payment. Any Milestone Payment shall be treated as including two components, respectively, a principal
component and an interest component, the amounts of which shall be determined as provided in Reg. Section 1.483-4(b) example (2)
using the 3-month test rate of interest provided for in Reg. Section 1.1274-4(a)(1)(ii) employing the semi-annual compounding period.
As to each such Milestone Payment paid in Parent Common Stock, shares representing the principal component and any shares representing
the interest component shall be represented by separate share certificates.



(f)          Recordkeeping.
From the Closing Date until the earlier of (A) such time as all Milestone Payments have been paid by Parent, or Parent has caused
them to be paid, pursuant to this Section 2.15 or (B) ninety (90) days after the expiration of the latest Milestone Deadline
Date (the “Milestone Period”), Parent shall, and shall cause its applicable Affiliates to, maintain reasonable
documentation, consistent with Parent’s customary practices and in compliance with applicable Laws, regarding its activities
relating to seeking and obtaining the Milestones (the “Milestone Records”). Further, notwithstanding anything
else to the contrary in this Section 2.15(f), Parent shall maintain the Milestone Records during any pending audit performed
by Member Representative regarding the Milestone Payments.



(g)          Audit
Rights. If Member Representative desires to pursue audit compliance with this Section 2.15, Member Representative shall
give written notice to Parent of its desire to conduct such audit (the “Audit Notice”). Within ten (10) Business
Days after Parent’s receipt of the Audit Notice, Parent shall afford Member Representative and an independent accounting
firm engaged by Member Representative (the “Representative’s Accountant”) reasonable access, during normal
business hours, to such information in the possession of Parent and its Affiliates as may reasonably be requested by Member Representative
and the Representative’s Accountant for the purposes of determining compliance with this Section 2.15. Member Representative
may deliver an Audit Notice no more often than one (1) time per year.



19







(h)          Reporting.
Until the expiration of the Milestone Period, Parent shall provide Member Representative, on a semi-annual basis, on or about February
1st and August 1st of each year within such period, a written summary in reasonable detail regarding the status of its efforts
to achieve the Milestones and Parent’s progress with respect thereto, including Parent’s then-current plans for progressing
toward the achievement thereof (each such report, an “Update Report”). Within twenty (20) Business Days after
delivery of an Update Report, if Member Representative requests in writing a meeting with representatives of Parent to discuss
such report, Parent shall make available for such a meeting to be held in Parent’s offices one or more representatives (as
determined by Parent); provided, however, that, for the avoidance of doubt, at any such meeting, other representatives (including
counsel and advisors) of Parent and Member Representative may be present. Member Representative may not request more than two (2)
meetings with the Buyer in any twelve (12) month period. In the absence of a timely written request by Member Representative for
such a meeting, Parent shall not have any further obligations to hold any meeting. All information contained in any Update Report,
or conveyed to Member Representative in any meeting or other communication regarding an Update Report, shall be subject to the
confidentiality obligations set forth herein. Each of the Parent and Member Representative shall be solely responsible for bearing
its own costs associated with exercising its rights or performing its obligation under this Section 2.15(h).



(i)          Adjusted
Pro Rata Interest. At least three (3) Business Days before Parent’s payment of any Milestone, Member Representative will
provide Parent with an updated calculation of each Member’s Adjusted Pro Rata Interest (the “Updated Adjusted Pro
Rata Interest”) that will replace the previous percentage of such Member’s Adjusted Pro Rata Interest (the “Replaced
Adjusted Pro Rata Interest”). After Member Representative delivers the Updated Adjusted Pro Rata Interest to Parent,
all references in this Agreement to a Member’s Adjusted Pro Rata Interest shall be equal to the Updated Adjusted Pro Rata
Interest and Parent will not use the Replaced Adjusted Pro Rata Interest for any future calculations. Member Representative’s
delivery of each Member’s Updated Adjusted Pro Rata Interest to Parent will have no effect on previous calculations under
this Agreement made using the Replaced Adjusted Pro Rata Interest.



(j)          Pro
Rata Interest. At least three (3) Business Days before Parent’s payment of any Milestone, Member Representative will
provide Parent with an updated calculation of each Member’s Pro Rata Interest (the “Updated Pro Rata Interest”)
that will replace the previous percentage of such Member’s Pro Rata Interest (the “Replaced Pro Rata Interest”)
effective as of the date Parent paid the most recent Milestone Payment to the Members. After Member Representative delivers the
Updated Pro Rata Interest to Parent, all references in this Agreement to a Member’s Pro Rata Interest shall be equal to the
Updated Pro Rata Interest. Member Representative’s delivery of each Member’s Updated Pro Rata Interest to Parent will
have no effect on previous calculations under this Agreement made using the Replaced Pro Rata Interest.



(k)          Adjustments
for Tax Purposes. Any payments made pursuant to this Section 2.15 that are not characterized as interest in accordance
with Section 2.15(e) shall, unless otherwise required by Law, be treated by the parties for Tax purposes as an adjustment
to the consideration paid for the Membership Interests.



20







Section 2.16.   Consideration
Spreadsheet.



(a)          At
least three (3) Business Days before the Closing (the “Consideration Determination Date”), the Company shall
prepare and deliver to Parent a spreadsheet (the “Consideration Spreadsheet”), certified by the President &
Chief Executive Officer of the Company, which shall set forth, as of the Closing Date and immediately prior to the Effective Time

(iii)        the
Pro Rata Interest of the Members (effective as of the Effective Time); and



(iv)         the
Adjusted Pro Rata Interest of the Members (effective as of the Effective Time).



(b)          Each
Member consents and agrees that, for the purposes of determining the Member’s Portion of the Merger Consideration, the value
of the shares of Parent Common Stock shall be the Parent Share Value. The Members further agree that any Preferred Return (as defined
in the Operating Agreement) will cease to accrue as of the Consideration Determination Date.



(c)          The
parties agree that Parent and Merger Sub shall be entitled to rely on the Consideration Spreadsheet in making payments under this
ARTICLE II and Parent and Merger Sub shall not be responsible for the calculations or the determinations regarding such
calculations in such Consideration Spreadsheet.

in good standing under the Laws of the jurisdiction of its incorporation. Each of Parent and Merger Sub has full corporate power
and authority to enter into and perform its obligations under this Agreement and the Ancillary Documents to which it is a party
and to consummate the transactions contemplated hereby and thereby. The execution, delivery and performance by Parent and Merger
Sub of this Agreement and any Ancillary Document to which they are a party and the consummation by Parent and Merger Sub of the
transactions contemplated hereby and thereby have been duly authorized by all requisite corporate action on the part of Parent
and Merger Sub and no other corporate proceedings on the part of Parent and Merger Sub are necessary to authorize the execution,
delivery and performance of this Agreement or to consummate the Merger and the other transactions contemplated hereby and thereby.
This Agreement has been duly executed and delivered by Parent and Merger Sub, and (assuming due authorization, execution and delivery
by each other party hereto) this Agreement constitutes a legal, valid and binding obligation of Parent and Merger Sub enforceable
against Parent and Merger Sub in accordance with its terms, subject to the effect of any applicable bankruptcy, reorganization,
insolvency, moratorium, fraudulent conveyance or similar laws relating to or affecting creditors’ rights generally and subject,
as to enforceability, to the effect of general principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law). When each Ancillary Document to which Parent or Merger Sub is or will be a party has been duly
executed and delivered by Parent or Merger Sub (assuming due authorization, execution and delivery by each other party thereto),
such Ancillary Document will constitute a legal and binding obligation of Parent or Merger Sub enforceable against it in accordance
with its terms.



Section 4.02.   No
Conflicts; Consents. The execution, delivery and performance by Parent and Merger Sub of this Agreement and the Ancillary Documents
to which they are a party, and the consummation of the transactions contemplated hereby and thereby, do not and will not: (a) conflict
with or result in a violation or breach of, or default under, any provision of the certificate of incorporation, by-laws or other
organizational documents of Parent or Merger Sub; (b) conflict with or result in a material violation or breach of any provision
of any Law or Governmental Order applicable to Parent or Merger Sub; or (c) require the consent, notice or other action by any
Person under any Contract to which Parent or Merger Sub is a party. No consent, approval, Permit, Governmental Order, declaration
or filing with, or notice to, any Governmental Authority is required by or with respect to Parent or Merger Sub in connection with
the execution, delivery and performance of this Agreement and the Ancillary Documents and the consummation of the transactions
contemplated hereby and thereby, except for the filing of the Delaware Certificate of Merger with the Secretary of State of Delaware.



Section 4.03.   No

business activities or conducted any operations other than in connection with the transactions contemplated hereby.

has filed or furnished (as applicable) in a timely manner with the Securities and Exchange Commission (the “SEC”)
all forms, reports, schedules, statements, filings, prospectuses and registration, proxy and other documents and statements required
by it to be filed or furnished as applicable since and including January 1, 2015 under the Exchange Act (all such forms, reports,
schedules, statements, filings, prospectuses and registration, proxy and other documents and statements filed by Parent with the
SEC under the Exchange Act since January 1, 2015, together with all amendments thereto and including all exhibits and schedules
thereto and documents incorporated by reference therein, collectively, the “Parent SEC Documents”). As of their
respective effective dates (in the case of Parent SEC Documents that are registration statements filed pursuant to the requirements
of the Securities Act) and as of the respective dates of the last amendment filed with the SEC (in the case of all other Parent
SEC Documents), the Parent SEC Documents complied in all material respects with the requirements of the Exchange Act and the rules
and regulations of the SEC promulgated thereunder, each as in effect on the applicable date referred to above, applicable to such
Parent SEC Documents, and none of the Parent SEC Documents as of such respective dates contained any untrue statement of a material
fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in
light of the circumstances under which they were made, not misleading.



47







(b)          The
consolidated financial statements (including all related notes and schedules) of Parent and its Subsidiaries included in the Parent
SEC Documents present fairly in all material respects the consolidated financial position of Parent and its Subsidiaries, as at
the respective dates thereof, and the consolidated results of their operations and their cash flows for the respective periods
then ended (subject, in the case of the unaudited statements, to normal year-end or period-end adjustments and to any other adjustments
described therein, including the notes thereto) and were prepared in conformity with GAAP (except, in the case of the unaudited
statements, as permitted by the SEC) applied on a consistent basis during the periods involved (except as may be expressly indicated
therein or in the notes thereto). No Subsidiary of Parent is subject to periodic reporting requirements of the Exchange Act.



(c)          The
records, systems, controls, data and information of Parent are recorded, stored, maintained and operated under means (including
any electronic, mechanical or photographic process, whether computerized or not) that are under the exclusive ownership and direct
control of Parent or their accountants (including all means of access thereto and therefrom). Parent has implemented and maintains
a system of internal accounting controls sufficient to provide reasonable assurances regarding the reliability of financial reporting
and the preparation of financial statements in accordance with GAAP.



Section 4.05.   Ownership
of Assets. Parent has good and marketable title to, or, in the case of property held under a lease or other Contract, a sole
and exclusive, enforceable leasehold interest in, or adequate rights to use, all of its properties, rights and assets, whether
real or personal and whether tangible or intangible.



Section 4.06.   Brokers.

Section 4.07.   Parent

policy of the Parent (collectively, the “Parent Insurance Policies”), including policy number, type, coverage,
underwriter, and true and complete copies of such Parent Insurance Policies have been made available to the Company. Such Parent
Insurance Policies are in full force and effect and shall remain in full force and effect following the consummation of the transactions
contemplated by this Agreement. Parent has not received any written notice of cancellation of, premium increase with respect to,
or alteration of coverage under, any of such Parent Insurance Policies. All premiums due on such Parent Insurance Policies have
either been paid or, if due and payable prior to Closing, will be paid prior to Closing in accordance with the payment terms of
each Parent Insurance Policy. The Parent Insurance Policies do not provide for any retrospective premium adjustment or other experience-based
liability on the part of Parent. All such Parent Insurance Policies (a) are valid and binding in accordance with their terms; (b)
are provided by carriers who are financially solvent; and (c) have not been subject to any lapse in coverage. There are no claims
related to the business of Parent pending under any such Parent Insurance Policies as to which coverage has been questioned, denied
or disputed or in respect of which there is an outstanding reservation of rights. Parent is not in default under, and has not otherwise
failed to comply with, in any material respect, any provision contained in any such Parent Insurance Policy. The Parent Insurance
Policies are of the type and in the amounts customarily carried by Persons conducting a business similar to Parent and are sufficient
for compliance with all applicable Laws and Contracts to which Parent is a party or by which it is bound.



Section 4.08.   Legal
Proceedings. Except as set forth in the Parent SEC Documents, there are no Actions pending or, to Parent’s Knowledge,
threatened (a) against or by Parent or Merger Sub affecting any of their properties or assets; or (b) against or by Parent or Merger
Sub that challenges or seeks to prevent, enjoin or otherwise delay the transactions contemplated by this Agreement. To the Knowledge
of Parent and Merger Sub, no event has occurred or circumstances exist that may give rise to, or serve as a basis for, any such
Action.



Section 4.09.   Capitalization.



(a)          As
of the date of this Agreement, the authorized capital stock of Parent consists of 200,000,000 shares of Parent Common Stock, of
which 22,232,135 shares of Parent Common Stock, are issued and outstanding, all of which are validly issued, fully paid and nonassessable.



(b)          Parent
owns all of the issued and outstanding shares of capital stock (or other equity securities) in Merger Sub. Except as described
in the Parent SEC Documents, there are no outstanding securities convertible into, exchangeable for or carrying the right to acquire
equity securities of Parent or Merger Sub, or subscriptions, warrants, options, rights (including preemptive rights), stock appreciation
rights, phantom stock interests, or other arrangements or commitments obligating either Parent or Merger Sub to issue or dispose
of any of its respective equity securities or any ownership interest therein. There are no existing agreements, subscriptions,
options, warrants, calls, commitments, trusts (voting or otherwise), or rights of any kind whatsoever between Parent or a Merger
Sub on the one hand and any Person on the other hand with respect to the capital stock of any Subsidiary of Parent or Merger Sub.
Other than as listed in Section 4.09(b) of the Parent Disclosure Schedules, neither Parent nor Merger Sub owns, directly
or indirectly, any stock of or any other equity interest in any other Person.



(c)          The
shares of Parent Common Stock to be issued pursuant to this Agreement will, upon issuance, be (i) duly authorized, validly issued,
fully paid and non-assessable, and (ii) voting stock.

are no outstanding contractual obligations of Parent or any of its Subsidiaries to repurchase, redeem or otherwise acquire any
capital stock of or other equity interests in Parent and/or any of its Subsidiaries.

forecasts and other forward-looking information, as well as certain business plan information, regarding the Company and its business

Merger Sub and Parent are familiar; and (b) Merger Sub and Parent hereby waive any claim against the Company or its Representatives
with respect to any information described in this Section 4.10 unless any such information is expressly addressed or included
in a representation or warranty contained in ARTICLE III of this Agreement, and have relied solely on the results of their
own independent investigation and on the representations, warranties, agreements and covenants made by the Company and contained
in this Agreement. Accordingly, Merger Sub and Parent hereby acknowledge and agree that neither the Company nor its Representatives,
has made or is making any express or implied representation or warranty with respect to such estimates, projections, forecasts,
forward-looking statements or business plans (including the reasonableness of the assumptions underlying such estimates, projections,
forecasts, forward-looking statements or business plans) unless any such information is expressly addressed or included in a representation
or warranty contained in ARTICLE IIIof this Agreement.



Section 4.11.   No
Other Representations or Warranties. EXCEPT FOR THE REPRESENTATIONS AND WARRANTIES CONTAINED IN THIS AGREEMENT AND ANY ANCILLARY
DOCUMENT, NEITHER PARENT NOR MERGER SUB MAKES ANY OTHER EXPRESS OR IMPLIED REPRESENTATION OR WARRANTY, INCLUDING WITH RESPECT TO

5.08 applies without the consent of such affected D&O Indemnified Party (it being expressly agreed that the D&O Indemnified
Parties to whom this Section 5.08 applies shall be third-party beneficiaries of this Section 5.08, each of whom may enforce

of MPS-IIIA preclinical studies, manufacturing of clinical vector, regulatory filings, conducting MPS-IIIA or MPS-IIIB clinical

Section 5.12.  Rule
144 Obligations. With a view to making available to the Members the benefits of Rule 144 promulgated under the Securities Act
or any other similar rule or regulation of the SEC that may at any time permit the Members to sell securities of Parent Common
Stock issued pursuant to this Agreement to the public without registration (“Rule 144”), for a period of one
year after the Closing, at all times during which there are shares of Parent Common Stock issued pursuant to this Agreement outstanding
that have not been previously (i) sold to or through a broker or dealer or underwriter in a public distribution or (ii) sold in
a transaction exempt from the registration and prospectus delivery requirements of the Securities Act under Section 4(a)(1) thereof,
in the case of either clause (i) or clause (ii) in such a manner that, upon the consummation of such sale, all transfer restrictions
and restrictive legends with respect to such shares are removed upon the consummation of such sale, Parent agrees to use commercially
reasonable efforts to:



(a)          make
and keep public information available, as those terms are understood and defined in Rule 144;



(b)          file

subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule
144; and



(c)          furnish
to each Member so long as such Member continues to owns Parent Common Stock issued pursuant to this Agreement, promptly upon request,
(i) a written statement by Parent, if true, that it has complied with the reporting requirements of Rule 144 and the Exchange Act,

without registration.



55







Section 5.13.   Listing
Compliance. Parent is in compliance with the requirements of the Exchange for continued listing of the Parent Common Stock
thereon. For a period of one year after the Closing, Parent will not take any action designed to, or likely to have the effect
of, terminating the registration of the Parent Common Stock under the Exchange Act or the listing of the Parent Common Stock on
the Exchange and will take all appropriate actions to ensure that the Parent Common Stock remains listed on the Exchange. Notwithstanding
the foregoing, Parent shall take any actions the board of directors of Parent determines to be in its best interests, including,
but not limited to, matters with respect to its registration under the Exchange Act or the listing on the Exchange.



Section 5.14.    Stockholder
Approval. Parent will provide each stockholder entitled to vote at a special meeting of stockholders of Parent (the “Stockholders

to extension for any SEC review) (the “Stockholder Meeting Deadline”), a proxy statement meeting the requirements
of Section 14 of the Exchange Act, and the related rules and regulations promulgated thereunder (the “Proxy Statement”)
soliciting each such stockholder’s affirmative vote at the Stockholder Meeting for approval of resolutions approving Parent’s
ability to issue any of the Milestone Payments, or portions thereof, in shares of Parent Common Stock in accordance with applicable
law, the rules and regulations of the Exchange, Parent’s certificate of incorporation and by-laws and the DGCL (“Stockholder
Approval”), and Parent will use its commercially reasonable efforts to solicit the Stockholder Approval of such resolutions
and to cause the board of directors of Parent to recommend to the stockholders that they approve such resolutions. For the avoidance
of doubt, none of the Members receiving Parent Common Stock as Closing Merger Consideration will be entitled to vote at any such
Stockholders Meeting. Parent will keep Member Representative apprised of the status of matters relating to the Proxy Statement
and the Stockholders Meeting, including promptly furnishing Member Representative and its counsel with copies of notices or other
communications related to the Proxy Statement, the Stockholders Meeting or the transactions contemplated hereby received by Parent
from the SEC or the Exchange. If, despite Parent’s commercially reasonable efforts, Stockholder Approval is not obtained
on or prior to the Stockholder Meeting Deadline, the Company shall not thereafter have any obligation to continue to try to obtain
such approval.

Section 6.01.    Tax
Covenants.



(a)          Without
the prior written consent of Parent, prior to the Closing, the Company, its Representatives and the Members shall not make or change
any election in respect of Taxes (other than the Tax Election), adopt or request permission of any Tax authority to change any
accounting method in respect of Taxes, enter into any closing agreement in respect of Taxes, settle any claim or assessment in
respect of Taxes, surrender or allow to expire any right to claim a refund of Taxes, file any amended Tax Return, consent to any
extension or waiver of the limitation period applicable to any claim or assessment in respect of Taxes, or make any application
for, negotiate or conclude a Tax ruling or arrangement with a Tax authority, whether or not in connection with the Merger, in each
case, except as explicitly contemplated in this Agreement. The Company shall timely file all of its Tax Returns as they become
due (taking all timely filed proper extension requests into account), all such Tax Returns to be true, correct and complete, and
the Company shall timely pay and discharge as they become due and payable all Taxes (other than Taxes contested in good faith by
the Company in appropriate proceedings), assessments and other governmental charges or levies imposed upon it or its income or
any of its property as well as all claims of any kind (including claims for labor, materials and supplies) that, if unpaid, may
by law become a lien or charge upon its properties.



(b)          All
transfer, documentary, sales, use, stamp, registration, value added and other such Taxes and fees (including any penalties and
interest) incurred in connection with this Agreement and the Ancillary Documents (including any real property transfer Tax and

Section 6.03.    Tax
Indemnification. Except to the extent treated as a Current Liability in the calculation of Closing Working Capital, the Members
shall, severally and not jointly (in accordance with their Pro Rata Interest), indemnify the Company, Parent, and each Parent Indemnitee
and hold them harmless from and against (a) any Loss attributable to any breach of or inaccuracy in any representation or warranty
made in Section 3.18; (b) any Loss attributable to any breach or violation of, or failure to fully perform, any covenant,
agreement, undertaking or obligation in this ARTICLE VI; (c) all Pre-Closing Taxes and any Taxes of the Company or relating
to the business of the Company for all Pre-Closing Tax Periods; (d) all Taxes of any member of an affiliated, consolidated, combined
or unitary group of which the Company (including, without limitation, any predecessor of the Company) is or was a member on or
prior to the Closing Date by reason of a liability under Treasury Regulation Section 1.1502-6 or any comparable provisions of foreign,
state or local Law; and (e) any and all Taxes of any person imposed on the Company arising under the principles of transferee or
successor liability or by contract, relating to an event or transaction (including, without limitation, the Tax Election) occurring
before the Closing. In each of the above cases, together with any out-of-pocket fees and expenses (including attorneys’ and
accountants’ fees) incurred in connection therewith, the Members shall, severally and not jointly (in accordance with their
Pro Rata Interest), reimburse Parent for any Taxes of the Company that are the responsibility of the Members pursuant to this Section
6.03 within ten (10) Business Days after payment of such Taxes by Parent or the Company.



Section 6.04.   Tax
Returns.



(a)          The
Company shall prepare and timely file, or cause to be prepared and timely filed, all Tax Returns required to be filed by it that
are due on or before the Closing Date (taking into account any extensions), and shall timely pay all Taxes that are due and payable
on or before the Closing Date (taking into account any extensions). Notwithstanding anything herein to the contrary, Member Representative
shall prepare and timely file, or cause to be prepared and timely filed, any federal U.S. Return of Partnership Income, Forms 1065
and applicable schedules thereto, on behalf of the Company, with respect to any period prior to the effective date of the Tax Election,
regardless of whether such partnership return is due on or before the Closing Date (taking into account any extensions); provided,
that no such Tax Return shall be filed without Parent’s consent (which may be given or withheld in Parent’s absolute
discretion) to the extent the Tax Return would be inconsistent in any respect with the representations and warranties in Section
3.18 if those representations and warranties were made as of the filing date of that Tax Return (or would cause those representations
and warranties to become incorrect or untrue in any respect), or with applicable past practice (unless otherwise required by Law
or change in relevant facts). Any such Tax Return shall be prepared in a manner consistent with any applicable past practice (unless
otherwise required by Law or by change in relevant facts).



(b)          Parent
shall prepare and timely file, or cause to be prepared and timely filed, all Tax Returns with respect to a Pre-Closing Tax Period
not filed by the Company under Section 6.04(a) and for any Straddle Period. Any such Tax Return shall be prepared in a manner
consistent with any applicable past practice (unless otherwise required by Law or a change in relevant facts) and, if it is an
income Tax Return, shall be submitted by Parent to Member Representative (together with schedules, statements and, to the extent
requested by Member Representative, supporting documentation) at least 45 days prior to the due date (including extensions) of
such Tax Return. If Member Representative objects to any item on any such Tax Return that relates to a Pre-Closing Tax Period,
it shall, within ten days after delivery of such Tax Return, notify Parent in writing that it so objects, specifying with particularity
any such item and stating the specific factual or legal basis for any such objection. If a notice of objection shall be duly delivered,
Parent and Member Representative shall negotiate in good faith and use their reasonable best efforts to resolve such items. If
Parent and Member Representative are unable to reach such agreement within ten days after receipt by Parent of such notice, the
disputed items shall be resolved by the Independent Accountant and any determination by the Independent Accountant shall be final.
The Independent Accountant shall resolve any disputed items within 20 days of having the item referred to it pursuant to such procedures
as it may require. If the Independent Accountant is unable to resolve any disputed items before the due date for such Tax Return,
the Tax Return shall be filed as prepared by Parent and then amended to reflect the Independent Accountant’s resolution.
The costs, fees and expenses of the Independent Accountant shall be borne one half by Parent and one half by Member Representative
on behalf of the Members. The preparation and filing of any Tax Return of the Company that does not relate to a Pre-Closing Tax
Period or Straddle Period shall be exclusively within the control of Parent.



58







Section 6.05.   Straddle
Period. In the case of Taxes that are payable with respect to a taxable period that begins before and ends after the Closing
Date (each such period, a “Straddle Period”), the portion of any such Taxes that are treated as Pre-Closing
Taxes for purposes of this Agreement shall be:



(a)          in
the case of Taxes (i) based upon, or related to, income, receipts, profits, wages, other transactions, capital or net worth, (ii)
imposed in connection with the sale, transfer or assignment of property, or (iii) required to be withheld, deemed equal to the
amount which would be payable if the taxable year ended with the close of business on the Closing Date; and



(b)          in
the case of other Taxes, deemed to be the amount of such Taxes for the entire period multiplied by a fraction the numerator of
which is the number of days in the period ending on and including the Closing Date and the denominator of which is the number of
days in the entire period.



Section 6.06.  Contests.
Parent agrees to give written notice to Member Representative of the receipt of any written notice by the Company, Parent or any
of Parent’s Affiliates which involves the assertion of any claim, or the commencement of any Action, in respect of which
an indemnity may be sought by Parent pursuant to this ARTICLE VI (a “Tax Claim”); provided, that
failure to comply with this provision shall not affect Parent’s right to indemnification hereunder. Parent shall control
the contest or resolution of any Tax Claim; provided, however, that Parent shall obtain the prior written consent of Member
Representative (which consent shall not be unreasonably withheld or delayed) before entering into any settlement of a claim or
ceasing to defend such claim; and, provided further, that Member Representative shall be entitled to participate in the
defense of such claim and to employ counsel of its choice for such purpose, the fees and expenses of which separate counsel shall
be borne solely by Member Representative.



Section 6.07.   Cooperation
and Exchange of Information. Member Representative, the Company and Parent shall provide each other with such cooperation and
information as either of them reasonably may request of the others in filing any Tax Return pursuant to this ARTICLE VI
or in connection with any audit or other proceeding in respect of Taxes of the Company. Such cooperation and information shall
include providing copies of relevant Tax Returns or portions thereof, together with accompanying schedules, related work papers
and documents relating to rulings or other determinations by Tax authorities.



59







Section 6.08.   Tax
Treatment of Indemnification Payments. Any indemnification payments pursuant to this ARTICLE VI shall be treated by
the parties for Tax purposes as an adjustment to the consideration paid for the Shares, unless otherwise required by Law.



Section 6.09.    FIRPTA
Statement. The Company shall have delivered to Parent properly executed statements from the Company that meets the requirements
of Treasury Regulation Sections 1.1445-2(c)(3) and 1.897-2(h)(1), dated as of the Closing Date and in the form and substance reasonably
satisfactory to Parent, along with written authorization for Parent to deliver such notice form to the Internal Revenue Service
on behalf of the Company upon Closing (the “FIRPTA Statement”).



Section 6.10.    Survival.
Notwithstanding anything in this Agreement to the contrary, the provisions of Section 3.18 and this ARTICLE VI shall
terminate after the full period of all applicable statutes of limitations (giving effect to any waiver, mitigation or extension
thereof) plus 60 days.



Section 6.11.   Overlap.
To the extent that any obligation or responsibility pursuant to ARTICLE VIII may overlap with an obligation or responsibility
pursuant to this ARTICLE VI, the provisions of this ARTICLE VI shall govern and the corresponding provision in ArticleVIII shall not apply.

Limitations.

Effect or similar qualification contained in or otherwise applicable to a representation or warranty.



(b)          The
Members shall have no liability for indemnification pursuant to Section 8.02(a) with respect to Losses for which indemnification
is provided unless the aggregate of all Losses exceeds One Hundred Fifty Thousand Dollars ($150,000) (the “Basket”),
in which case the Members shall be liable for all such Losses from the first dollar. The aggregate liability of the Members under

(d)          Notwithstanding
the foregoing, the limitations set forth in Section 8.04(b) and Section 8.04(c) shall not apply to Losses based upon,
arising out of, with respect to or by reason of any for and any claims arising from fraud, criminal activity or willful misconduct,

Losses (net of any costs to recover such insurance payments and any increased premiums resulting therefrom). Each Indemnified Party
shall act in good faith and a commercially reasonable manner to mitigate any Losses they may pay, incur, suffer or sustain for
which indemnification is available hereunder to the extent required by applicable Law. Notwithstanding the foregoing or anything

recovery under any insurance policy with respect to any Losses.



Section 8.05.   Indemnification
Procedures. The party making a claim under this ARTICLE VIII is referred to as the “Indemnified Party”,
and the party against whom such claims are asserted under this ARTICLE VIII is referred to as the “Indemnifying

Party, any references to Indemnifying Party (except provisions relating to an obligation to make payments) shall be deemed to refer
to Member Representative, and (ii) if Parent comprises the Indemnifying Party, any references to the Indemnified Party shall be

Person who is not a party to this Agreement or an Affiliate of a party to this Agreement or a Representative of the foregoing (a
“Third Party Claim”) against such Indemnified Party with respect to which the Indemnifying Party is obligated
to provide indemnification under this ArticleVIII, the Indemnified
Party shall give the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than 30 calendar days
after receipt of such notice of such Third Party Claim. The failure to give such prompt written notice shall not, however, relieve
the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying Party forfeits rights
or defenses by reason of such failure. Such notice by the Indemnified Party shall describe the Third Party Claim in reasonable
detail, shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably practicable,
of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party shall have the right to participate
in, or by giving written notice to the Indemnified Party, to assume the defense of any Third Party Claim at the Indemnifying Party’s
expense and by the Indemnifying Party's own counsel, and the Indemnified Party shall cooperate in good faith in such defense; provided,
that if the Indemnifying Party is a Member, such Indemnifying Party shall not have the right to defend or direct the defense
of any such Third Party Claim that (x) is asserted directly by or on behalf of a Person that is a supplier or customer of the Company,
or (y) seeks an injunction or other equitable relief against the Indemnified Parties. In the event that the Indemnifying Party
assumes the defense of any Third Party Claim, subject to Section 8.05(b), it shall have the right to take such action as
it deems necessary to avoid, dispute, defend, appeal or make counterclaims pertaining to any such Third Party Claim in the name
and on behalf of the Indemnified Party. The Indemnified Party shall have the right to participate in the defense of any Third Party
Claim with counsel selected by it subject to the Indemnifying Party's right to control the defense thereof. The fees and disbursements
of such counsel shall be at the expense of the Indemnified Party, provided, that if in the reasonable opinion of counsel
to the Indemnified Party, (A) there are legal defenses available to an Indemnified Party that are different from or additional
to those available to the Indemnifying Party; or (B) there exists a conflict of interest between the Indemnifying Party and the
Indemnified Party that cannot be waived, the Indemnifying Party shall be liable for the reasonable fees and expenses of counsel
to the Indemnified Party in each jurisdiction for which the Indemnified Party determines counsel is required. If the Indemnifying
Party elects not to compromise or defend such Third Party Claim, fails to promptly notify the Indemnified Party in writing of its
election to defend as provided in this Agreement, or fails to diligently prosecute the defense of such Third Party Claim, the Indemnified
Party may, subject to Section 8.05(b), pay, compromise, defend such Third Party Claim and seek indemnification for any and
all Losses based upon, arising from or relating to such Third Party Claim. Member Representative and Parent shall cooperate with
each other in all reasonable respects in connection with the defense of any Third Party Claim, including making available records
relating to such Third Party Claim and furnishing, without expense (other than reimbursement of actual out-of-pocket expenses)
to the defending party, management employees of the non-defending party as may be reasonably necessary for the preparation of the
defense of such Third Party Claim.



67







(b)          Settlement
of Third Party Claims. Notwithstanding any other provision of this Agreement, the Indemnifying Party shall not enter into settlement
of any Third Party Claim without the prior written consent of the Indemnified Party, except as provided in this Section 8.05(b).
If a firm offer is made to settle a Third Party Claim without leading to liability or the creation of a financial or other obligation
on the part of the Indemnified Party and provides, in customary form, for the unconditional release of each Indemnified Party from
all liabilities and obligations in connection with such Third Party Claim and the Indemnifying Party desires to accept and agree
to such offer, the Indemnifying Party shall give written notice to that effect to the Indemnified Party. If the Indemnified Party
fails to consent to such firm offer within ten days after its receipt of such notice, the Indemnified Party may continue to contest
or defend such Third Party Claim and in such event, the maximum liability of the Indemnifying Party as to such Third Party Claim
shall not exceed the amount of such settlement offer. If the Indemnified Party fails to consent to such firm offer and also fails
to assume defense of such Third Party Claim, the Indemnifying Party may settle the Third Party Claim upon the terms set forth in
such firm offer to settle such Third Party Claim. If the Indemnified Party has assumed the defense pursuant to Section 8.05(a),
it shall not agree to any settlement without the written consent of the Indemnifying Party (which consent shall not be unreasonably
withheld or delayed).



(c)          Tax
Claims. Notwithstanding any other provision of this Agreement, the control of any claim, assertion, event or proceeding in
respect of Taxes of the Company (including, but not limited to, any such claim in respect of a breach of the representations and
warranties in Section 3.18 hereof or any breach or violation of or failure to fully perform any covenant, agreement, undertaking
or obligation in ARTICLE VI) shall be governed exclusively by ARTICLE VI hereof.



Section 8.06.    Payments;
Holdback.



(a)          Once
a Loss is agreed to by the Indemnifying Party or finally adjudicated to be payable pursuant to this ARTICLE VIII, the Indemnifying
Party shall satisfy its obligations within fifteen (15) Business Days of such final, non-appealable adjudication by wire transfer
of immediately available funds. The parties hereto agree that should an Indemnifying Party not make full payment of any such obligations
within such 15 Business Day period, any amount payable shall accrue interest from and including the date of agreement of the Indemnifying
Party or final, non-appealable adjudication to the date such payment has been made at a rate per annum equal to the prime lending
rate prevailing during such period as published in The Wall Street Journal. Any interest payable hereunder shall be calculated
on a daily basis from the date such amounts were required to be paid until (but excluding) the date of actual payment, and on the
basis of a 360-day year.



(b)          Member
Representative shall have the option to satisfy any Losses payable to a Parent Indemnitee pursuant to ArticleVIII (i) by the payment of such Losses to Parent by wire transfer of immediately available funds or (ii) the directing the
Parent to deduct such number of shares of Parent Company Stock from the Holdback Amount as determined by dividing (A) the amount
of such Losses by (B) the Parent Share Value. Notwithstanding anything to the contrary in this Agreement, the aggregate liability
of each Member under this Agreement shall not exceed such Member’s Pro Rata Interest multiplied by the sum of the
Closing Merger Consideration plus the portion of the Holdback Amount actually received by the Members plus any satisfied
Milestones actually received by the Members.



Section 8.07.    Tax
Treatment of Indemnification Payments. All indemnification payments made under this Agreement shall be treated by the parties
for tax purposes as an adjustment to the consideration for the Membership Interests, unless otherwise required by Law.



68







Section 8.08.   Effect
of Investigation. The representations, warranties and covenants of the Indemnifying Party, and the Indemnified Party’s
right to indemnification with respect thereto, shall not be affected or deemed waived by reason of any investigation made by or
on behalf of the Indemnified Party (including by any of its Representatives) or by reason of the fact that the Indemnified Party
or any of its Representatives knew or should have known that any such representation or warranty is, was or might be inaccurate
or by reason of the Indemnified Party’s waiver of any condition set forth in Section 7.02 or Section 7.03,
as the case may be.



Section 8.09.   Exclusive
Remedies. Subject to Section 10.12, the parties acknowledge and agree that their sole and exclusive remedy with respect
to any and all claims (other than claims arising from fraud, criminal activity or willful misconduct on the part of a party hereto
in connection with the transactions contemplated by this Agreement) for any breach of any representation, warranty, covenant, agreement
or obligation set forth herein or otherwise relating to the subject matter of this Agreement, shall be pursuant to the indemnification
provisions set forth in ARTICLE VI and this ARTICLE VIII. In furtherance of the foregoing, each party hereby waives,
to the fullest extent permitted under Law, any and all rights, claims and causes of action for any breach of any representation,
warranty, covenant, agreement or obligation set forth herein or otherwise relating to the subject matter of this Agreement it may
have against the other parties hereto and their Affiliates and each of their respective Representatives arising under or based
upon any Law, except pursuant to the indemnification provisions set forth in ARTICLE VI and this ARTICLE VIII. Nothing
in this Section 8.09 shall (i) limit any Person’s right to seek and obtain any equitable relief to which any Person
shall be entitled or to seek any remedy on account of any party’s fraudulent, criminal or intentional misconduct (ii) or
operate as a waiver of any right that a Person may have as a shareholder of Parent from and after the Closing.



ARTICLE
IXTERMINATION



Section 9.01.   Termination.
This Agreement may be terminated at any time prior to the Closing:



(a)          by
the mutual written consent of the Company and Parent;



(b)          by
Parent by written notice to the Company if:



(i)          neither
Parent nor Merger Sub is then in material breach of any provision of this Agreement and there has been a breach, inaccuracy in
or failure to perform any representation, warranty, covenant or agreement made by the Company pursuant to this Agreement that would
give rise to the failure of any of the conditions specified in ARTICLE VII and such breach, inaccuracy or failure has not
been cured by the Company within ten days of the Company's receipt of written notice of such breach from Parent; or



(ii)         any
of the conditions set forth in Section 7.01 or Section 7.02 shall not have been, or if it becomes apparent that any
of such conditions will not be, fulfilled by July 31, 2015, subject to extension at the Parent’s election, unless such failure
shall be due to the failure of Parent to perform or comply with any of the covenants, agreements or conditions hereof to be performed
or complied with by it prior to the Closing;



69







(c)          by
the Company by written notice to Parent if:



(i)          the
Company is not then in material breach of any provision of this Agreement and there has been a breach, inaccuracy in or failure
to perform any representation, warranty, covenant or agreement made by Parent or Merger Sub pursuant to this Agreement that would
give rise to the failure of any of the conditions specified in ARTICLE VII and such breach, inaccuracy or failure has not
been cured by Parent or Merger Sub within ten days of Parent’s or Merger Sub’s receipt of written notice of such breach
from the Company; or



(ii)         any
of the conditions set forth in Section 7.01 or Section 7.03 shall not have been, or if it becomes apparent that any
of such conditions will not be, fulfilled by July 31, 2015, subject to extension at the Company’s election, unless such failure
shall be due to the failure of the Company to perform or comply with any of the covenants, agreements or conditions hereof to be
performed or complied with by it prior to the Closing; or



(d)          by
Parent or the Company if there shall be any Law that makes consummation of the transactions contemplated by this Agreement illegal
or otherwise prohibited or any Governmental Authority shall have issued a Governmental Order restraining or enjoining the transactions
contemplated by this Agreement, and such Governmental Order shall have become final and non-appealable.



Section 9.02.   Effect
of Termination. In the event of the termination of this Agreement in accordance with this Article, this Agreement shall forthwith
become void and there shall be no liability on the part of any party hereto except:



(a)          as
set forth in this ARTICLE IX, Section 5.02(b) and ARTICLE X hereof; and



(b)          that
nothing herein shall relieve any party hereto from liability for any willful breach of any provision hereof.



ARTICLE
XMISCELLANEOUS



Section 10.01.   Member
Representative.



(a)          By
approving this Agreement and the transactions contemplated hereby or by executing and delivering a Letter of Transmittal, each
Member shall have irrevocably authorized and appointed Member Representative as such Person’s representative and attorney-in-fact
to act on behalf of such Person with respect to this Agreement and to take any and all actions and make any decisions required
or permitted to be taken by Member Representative pursuant to this Agreement, including the exercise of the power to:



(i)          give
and receive notices and communications;



(ii)         agree
to, negotiate, enter into settlements and compromises of, and comply with orders or otherwise handle any other matters described
in Section 2.15;



70







(iii)        agree
to, negotiate, enter into settlements and compromises of, and comply with orders of courts with respect to claims for indemnification
made by Parent pursuant to ARTICLE VI and ARTICLE VIII;



(iv)         litigate,
arbitrate, resolve, settle or compromise any claim for indemnification pursuant to ARTICLE VI and ARTICLE VIII;



(v)          execute
and deliver all documents necessary or desirable to carry out the intent of this Agreement and any Ancillary Document;



(vi)         make
all elections or decisions contemplated by this Agreement and any Ancillary Document;



(vii)        engage,
employ or appoint any agents or representatives (including attorneys, accountants and consultants) to assist Member Representative
in complying with its duties and obligations; and



(viii)      take
all actions necessary or appropriate in the good faith judgment of Member Representative for the accomplishment of the foregoing.



Parent shall be entitled
to deal exclusively with Member Representative on all matters relating to this Agreement (including ARTICLE VIII) and shall
be entitled to rely conclusively (without further evidence of any kind whatsoever) on any document executed or purported to be
executed on behalf of any Member by Member Representative, and on any other action taken or purported to be taken on behalf of
any Member by Member Representative, as being fully binding upon such Person. Notices or communications to or from Member Representative
shall constitute notice to or from each of the Members. Any decision or action by Member Representative hereunder, including any
agreement between Member Representative and Parent relating to the defense, payment or settlement of any claims for indemnification
hereunder, shall constitute a decision or action of all Members and shall be final, binding and conclusive upon each such Person.
No Member shall have the right to object to, dissent from, protest or otherwise contest the same. The provisions of this Section,
including the power of attorney granted hereby, are independent and severable, are irrevocable and coupled with an interest and
shall not be terminated by any act of any one or Members, or by operation of Law, whether by death or other event.



(b)          Member
Representative may resign at any time, and may be removed for any reason or no reason by the vote or written consent of a majority
in interest of the Members according to each Member’s Pro Rata Interest (the “Majority Holders”); provided,
however, in no event shall Member Representative resign or be removed without the Majority Holders having first appointed a
new Member Representative who shall assume such duties immediately upon the resignation or removal of Member Representative. In
the event of the death, incapacity, resignation or removal of Member Representative, a new Member Representative shall be appointed
by the vote or written consent of the Majority Holders. Notice of such vote or a copy of the written consent appointing such new
Member Representative shall be sent to Parent, such appointment to be effective upon the later of the date indicated in such consent
or the date such notice is received by Parent; provided, that until such notice is received, Parent, Merger Sub and the Surviving
Entity shall be entitled to rely on the decisions and actions of the prior Member Representative as described in Section 10.01(a)
above.



71







(c)          Member
Representative shall not be liable to the Members for actions taken pursuant to this Agreement, except to the extent such actions
shall have been determined by a court of competent jurisdiction to have constituted gross negligence or involved fraud, intentional
misconduct or bad faith (it being understood that any act done or omitted pursuant to the advice of counsel, accountants and other
professionals and experts retained by Member Representative shall be conclusive evidence of good faith). The Members shall severally
and not jointly (in accordance with their Pro Rata Interest), indemnify and hold harmless Member Representative from and against,
compensate it for, reimburse it for and pay any and all losses, liabilities, claims, actions, damages and expenses, including reasonable
attorneys’ fees and disbursements, arising out of and in connection with its activities as Member Representative under this
Agreement (the “Representative Losses”), in each case as such Representative Loss is suffered or incurred; provided,
that in the event it is finally adjudicated that a Representative Loss or any portion thereof was primarily caused by the gross
negligence, fraud, intentional misconduct or bad faith of Member Representative, Member Representative shall reimburse the Members
the amount of such indemnified Representative Loss attributable to such gross negligence, fraud, intentional misconduct or bad
faith. Parent will, or will cause the Surviving Entity to, promptly reimburse Member Representative for any reasonable out-of-pocket
administrative expenses up to a maximum of one hundred thousand dollars ($100,000) (the “Representative Fund”)
reasonably incurred by Member Representative in the course of performing such Member Representative duties necessary to effect
the transactions contemplated by this Agreement, against appropriate receipts or other supporting documentation, as may be requested
by Parent or the Surviving Entity. All requests for reimbursement from the Representative Fund by Member Representative must be
received, together with the appropriate receipts and supporting documentation, by Parent no later than the earlier of (i) the Third
Milestone Date and (ii) the Satisfaction Date of the Third Milestone.



Section 10.02.   Expenses.
Except as otherwise expressly provided herein, all costs and expenses, including, without limitation, fees and disbursements of
counsel, financial advisors and accountants, incurred in connection with this Agreement and the transactions contemplated hereby
shall be paid by the party incurring such costs and expenses, whether or not the Closing shall have occurred.



Section 10.03.   Notices.
All notices, requests, consents, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed
to have been given (a) when delivered by hand (with written confirmation of receipt); (b) when received by the addressee if sent
by a nationally recognized overnight courier (receipt requested); (c) on the date sent by facsimile or e-mail of a PDF document
(with confirmation of transmission) if sent during normal business hours of the recipient, and on the next Business Day if sent
after normal business hours of the recipient or (d) on the third day after the date mailed, by certified or registered mail, return
receipt requested, postage prepaid. Such communications must be sent to the respective parties at the following addresses (or at
such other address for a party as shall be specified in a notice given in accordance with this Section 10.03):

part of, this Agreement to the same extent as if they were set forth verbatim herein.



73







Section 10.05.  Headings.
The headings in this Agreement are for reference only and shall not affect the interpretation of this Agreement.



Section 10.06.   Severability.
If any term or provision of this Agreement is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality
or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such term
or provision in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or unenforceable,
the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as
closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally
contemplated to the greatest extent possible.



Section 10.07.   Entire
Agreement. This Agreement and the Ancillary Documents constitute the sole and entire agreement of the parties to this Agreement
with respect to the subject matter contained herein and therein, and supersede all prior and contemporaneous understandings and
agreements, both written and oral, with respect to such subject matter. In the event of any inconsistency between the statements
in the body of this Agreement and those in the Ancillary Documents, the Exhibits and Disclosure Schedules (other than an exception
expressly set forth as such in the Disclosure Schedules), the statements in the body of this Agreement will control.



Section 10.08.   Successors
and Assigns. This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective
successors and permitted assigns. Neither party may assign its rights or obligations hereunder without the prior written consent
of the other party, which consent shall not be unreasonably withheld or delayed. No assignment shall relieve the assigning party

Third-Party Beneficiaries. Except as provided in Section 5.08, Section 6.03 and ARTICLE VIII, this Agreement
is for the sole benefit of the parties hereto and their respective successors and permitted assigns and nothing herein, express
or implied, is intended to or shall confer upon any other Person or entity any legal or equitable right, benefit or remedy of any
nature whatsoever under or by reason of this Agreement.



Section 10.10.  Amendment
and Modification; Waiver. This Agreement may only be amended, modified or supplemented by an agreement in writing signed by
Parent, Merger Sub and the Company at any time prior to the Effective Time; provided, however, that after the Requisite
Member Approval is obtained, there shall be no amendment or waiver that, pursuant to applicable Law, requires further approval
of the Members, without the receipt of such further approvals. Any failure of Parent or Merger Sub, on the one hand, or the Company,
on the other hand, to comply with any obligation, covenant, agreement or condition herein may be waived by the Company (with respect
to any failure by Parent or Merger Sub) or by Parent or Merger Sub (with respect to any failure by the Company), respectively,
only by a written instrument signed by the party granting such waiver, but such waiver or failure to insist upon strict compliance
with such obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with respect to, any subsequent
or other failure.



74

Law; Submission to Jurisdiction; Waiver of Jury Trial.



(a)          This
Agreement shall be governed by and construed in accordance with the internal laws of the State of Delaware without giving effect
to any choice or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction).



(b)          ANY
LEGAL SUIT, ACTION OR PROCEEDING ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE ANCILLARY DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED
HEREBY OR THEREBY MAY BE INSTITUTED IN THE FEDERAL COURTS OF THE UNITED STATES OF AMERICA OR THE COURTS OF THE STATE OF NEW YORK
IN EACH CASE LOCATED IN THE CITY OF NEW YORK AND COUNTY OF NEW YORK, AND EACH PARTY IRREVOCABLY SUBMITS TO THE EXCLUSIVE JURISDICTION
OF SUCH COURTS IN ANY SUCH SUIT, ACTION OR PROCEEDING. SERVICE OF PROCESS, SUMMONS, NOTICE OR OTHER DOCUMENT BY MAIL TO SUCH PARTY’S
