AGREEMENT


 


		1.	Company
                                         Stockholder Written Consent and Related Matters.



 


(a)           As
promptly as reasonably practicable (and in any event within two (2) Business Days) following the time at which the Registration
Statement / Proxy Statement is declared effective under the Securities Act, the Stockholders shall duly execute and deliver to
the Company and Longview the Company Stockholder Written Consent under which they shall irrevocably and unconditionally consent
to the matters, actions and proposals contemplated by Section 5.13(b) (Transaction Support Agreements; Company
Stockholder Approval; PIPE Investor Subscription Agreements) of the Business Combination Agreement. Without limiting the generality
of the first sentence of this Section 1(a), prior to the Closing, the Stockholders shall vote (or cause to be voted)
the Subject Company Shares against and withhold consent with respect to (A) any Company Acquisition Proposal or (B) any
other matter, action or proposal that would reasonably be expected to result in (x) a breach of any of the Company’s
covenants, agreements or obligations under the Business Combination Agreement or (y) any of the conditions to the Closing
set forth in Sections 6.1 or 6.2 of the Business Combination Agreement not being satisfied.


 


(b)           Without
limiting any other rights or remedies of Longview, each Stockholder hereby irrevocably appoints Longview or any individual designated
by Longview as such Stockholder’s agent, attorney-in-fact and proxy (with full power of substitution and resubstituting),
for and in the name, place and stead of such Stockholder, to attend on behalf of such Stockholder any meeting of the Company Stockholders
with respect to the matters described in Section 1(a), to include such Stockholder’s Subject Company Shares
in any computation for purposes of establishing a quorum at any such meeting of the Company Stockholders, to vote (or cause to
be voted) such Stockholder’s Subject Company Shares or consent (or withhold consent) with respect to any of the matters
described in Section 1(a) in connection with any meeting of the Company Stockholders or any action by written
consent by the Company Stockholders (including the Company Stockholder Written Consent), in each case, in the event that such
Stockholder fails to perform or otherwise comply with the covenants, agreements or obligations set forth in Section 1(a).


 


(c)           The
proxy granted by each Stockholder pursuant to Section 1(b) is coupled with an interest sufficient at law to support
an irrevocable proxy and is granted in consideration for Longview entering into the Business Combination Agreement and agreeing
to consummate the transactions contemplated thereby. The proxy granted by each Stockholder pursuant to Section 1(b) is
also a durable proxy and shall survive the bankruptcy, dissolution, death, incapacity or other inability to act by such Stockholder
and shall revoke any and all prior proxies granted by such Stockholder with respect to its Subject Company Shares. The vote or
consent of the proxyholder in accordance with Section 1(b) and with respect to the matters in Section 1(a) shall
control in the event of any conflict between such vote or consent by the proxyholder of the Subject Company Shares and a vote
or consent by a Stockholder of the Subject Company Shares (or any other Person with the power to vote the Subject Company Shares)
with respect to the matters in Section 1(a). The proxyholder may not exercise the proxy granted pursuant to Section 1(b) on
any matter except those provided in Section 1(a). For the avoidance of doubt, the Stockholder may vote the Subject
Company Shares on all other matters, subject to, for the avoidance of doubt, the other applicable covenants, agreements and obligations
set forth in this Agreement.

		2.	Other
                                         Covenants and Agreements.



 


(a)           Each
Stockholder shall be bound by and subject to Sections 5.3(a) (Confidentiality) and Section 5.4(a) (Public
Announcements) of the Business Combination Agreement to the same extent as such provisions apply to the parties to the Business
Combination Agreement, as if such Stockholder is directly party thereto, and each Stockholder and Dr. Rothberg shall be bound
by and subject to the first sentence of Section 5.6(a) (Exclusive Dealing) and Section 8.18
(Trust Account Waiver) of the Business Combination Agreement to the same extent as such provisions apply to the Company, as if
such Stockholder is directly party thereto. Dr. Rothberg shall, in his capacity has Chairman of the Board of Directors of
the Company, cause to be done such further acts and things as may be reasonably necessary or advisable to cause the Company to
fulfill its obligations under the Business Combination Agreement and consummate the transactions contemplated thereby.


 


(b)           Each
Stockholder and Dr. Rothberg acknowledges and agrees that Longview and the other Longview Parties are entering into the Business
Combination Agreement in reliance upon such Stockholder entering into this Agreement and agreeing to be bound by, and perform,
or otherwise comply with, as applicable, the agreements, covenants and obligations contained in this Agreement and but for such
Stockholder and Dr. Rothberg entering into this Agreement and agreeing to be bound by, and perform, or otherwise comply with,
as applicable, the agreements, covenants and obligations contained in this Agreement, Longview and the other Longview Parties
would not have entered into or agreed to consummate the transactions contemplated by the Business Combination Agreement.


 


3.            Stockholder
Representations and Warranties. Each of the Stockholders and Dr. Rothberg represents and warrants to Longview, on behalf
of him or itself, as follows:


 


(a)           Each
Stockholder is a limited liability company, trust or other applicable entity duly organized or formed, as applicable, validly
existing and in good standing (or the equivalent thereof, if applicable, in each case, with respect to the jurisdictions that
recognize the concept of good standing or any equivalent thereof) under the Laws of its jurisdiction of formation or organization
(as applicable).


 


(b)           Each
Stockholder has the requisite limited liability company, trust or other similar power and authority to execute and deliver this
Agreement, to perform its covenants, agreements and obligations hereunder (including, for the avoidance of doubt, those covenants,
agreements and obligations hereunder that relate to the provisions of the Business Combination Agreement), and to consummate the
transactions contemplated hereby. The execution and delivery of this Agreement has been duly authorized by all necessary limited
liability company, trust (or other similar) action on the part of each Stockholder. This Agreement has been duly and validly executed
and delivered by the Stockholders and Dr. Rothberg and constitutes a valid, legal and binding agreement of each Stockholder
and Dr. Rothberg (assuming that this Agreement is duly authorized, executed and delivered by Longview), enforceable against
each Stockholder and Dr. Rothberg in accordance with its terms (subject to applicable bankruptcy, insolvency, reorganization,
moratorium or other Laws affecting generally the enforcement of creditors’ rights and subject to general principles of equity).


 


(c)           No
consent, approval or authorization of, or designation, declaration or filing with, any Governmental Entity is required on the
part of any Stockholder or Dr. Rothberg with respect to such Stockholder’s or Dr. Rothberg’s execution,
delivery or performance of its covenants, agreements or obligations under this Agreement (including, for the avoidance of doubt,
those covenants, agreements and obligations under this Agreement that relate to the provisions of the Business Combination Agreement)
or the consummation of the transactions contemplated hereby, except for any consents, approvals, authorizations, designations,
declarations, waivers or filings, the absence of which would not adversely affect the ability of the Stockholders or Dr. Rothberg
to perform, or otherwise comply with, any of its covenants, agreements or obligations hereunder in any material respect.


 






    3 


     


    

 


(d)           None
of the execution or delivery of this Agreement by the Stockholders and Dr. Rothberg, the performance by the Stockholders
and Dr. Rothberg of any of its covenants, agreements or obligations under this Agreement (including, for the avoidance of
doubt, those covenants, agreements and obligations under this Agreement that relate to the provisions of the Business Combination
Agreement) or the consummation of the transactions contemplated hereby will, directly or indirectly (with or without due notice
or lapse of time or both) (i) result in any breach of any provision of any Stockholder’s Governing Documents, (ii) result
in a violation or breach of, or constitute a default or give rise to any right of termination, Consent, cancellation, amendment,
modification, suspension, revocation or acceleration under, any of the terms, conditions or provisions of any Contract to which
any Stockholder or Dr. Rothberg is a party, (iii) violate, or constitute a breach under, any Order or applicable Law
to which Dr. Rothberg, any Stockholder or any of their respective properties or assets are bound or (iv) result in the
creation of any Lien upon the Subject Company Shares, except, in the case of any of clauses (ii) and (iii) above,
as would not adversely affect the ability of the Stockholders or Dr. Rothberg to perform, or otherwise comply with, any of
its covenants, agreements or obligations hereunder in any material respect.


 


(e)           Each
Stockholder is the record and beneficial owner of its Subject Company Shares, free and clear of all Liens (other than transfer
restrictions under applicable Securities Law or under the Company Stockholders Agreements). Except for the Equity Securities of
the Company set forth on Schedule A hereto with respect to each Stockholder, together with any other Equity Securities
of the Company that such Stockholder acquires record or beneficial ownership after the date hereof that is either permitted pursuant
to, or acquired in accordance with, Section 5.1(b)(iv) of the Business Combination Agreement, such Stockholder
does not own, beneficially or of record, any Equity Securities of any Group Company. Except as otherwise expressly contemplated
by the Company Stockholders Agreements and any agreement existing on the date hereof and made available to Longview or that is
entered into in accordance with the Business Combination Agreement, no Stockholder has the right to acquire any Equity Securities
of any Group Company. Each Stockholder has the sole right to vote (and provide consent in respect of, as applicable) the Subject
Company Shares and, except for this Agreement, the Business Combination Agreement, the Company Stockholders Agreements and any
Contract with respect to a Permitted Transfer, no Stockholder is party to or bound by (i) any option, warrant, purchase right,
or other Contract that would (either alone or in connection with one or more events, developments or events (including the satisfaction
or waiver of any conditions precedent)) require such Stockholder to Transfer any of its Subject Company Shares or (ii) any
voting trust, proxy or other Contract with respect to the voting or Transfer of any of its Subject Company Shares.

(f)           There
is no Proceeding pending or, to Dr. Rothberg’s or each Stockholder’s knowledge, threatened against Dr. Rothberg
or such Stockholder that, if adversely decided or resolved, would reasonably be expected to adversely affect the ability of such
Stockholder to perform, or otherwise comply with, any of its covenants, agreements or obligations under this Agreement in any
material respect.


 


(g)            Dr. Rothberg
and each Stockholder, on its own behalf and on behalf of its Representatives, acknowledges, represents, warrants and agrees that
(i) it has conducted its own independent review and analysis of, and, based thereon, has formed an independent judgment concerning,
the business, assets, condition, operations and prospects of, the Longview Parties and (ii) it has been furnished with or
given access to such documents and information about the Longview Parties and their respective businesses and operations as it
and its Representatives have deemed necessary to enable it to make an informed decision with respect to the execution, delivery
and performance of this Agreement, the other Ancillary Documents to which it is or will be a party and the transactions contemplated
hereby and thereby.


 


(h)            In
entering into this Agreement and the other Ancillary Documents to which it is or will be a party, each Stockholder has relied
solely on its own investigation and analysis and the representations and warranties expressly set forth in the Ancillary Documents
to which it is or will be a party and no other representations or warranties of any Longview Party (including, for the avoidance
of doubt, none of the representations or warranties of any Longview Party set forth in the Business Combination Agreement or any
other Ancillary Document), any Longview Non-Party Affiliate or any other Person, either express or implied, and such Stockholder,
on its own behalf and on behalf of its Representatives, acknowledges, represents, warrants and agrees that, except for the representations
and warranties expressly set forth in the Ancillary Documents to which it is or will be a party, none of the Longview Parties,
any Longview Non-Party Affiliate or any other Person makes or has made any representation or warranty, either express or implied,
in connection with or related to this Agreement, the Ancillary Documents to which it is or will be a party or the transactions
contemplated hereby or thereby.


 


4.            Transfer

into (i) any option, warrant, purchase right, or other Contract that would (either alone or in connection with one or more
events, developments or events (including the satisfaction or waiver of any conditions precedent)) require such Stockholder to
Transfer its Subject Company Shares or (ii) any voting trust, proxy or other Contract with respect to the voting or Transfer
of its Subject Company Shares, or (c) take any actions in furtherance of any of the matters described in the foregoing clauses
(a) or (b). For purposes of this Agreement, “Transfer” means any, direct or indirect, sale,

5.            Termination.
This Agreement shall automatically terminate, without any notice or other action by any Party, and be void ab initio upon
the earlier of (a) the Effective Time; and (b) the termination of the Business Combination Agreement in accordance with
its terms. Upon termination of this Agreement as provided in the immediately preceding sentence, none of the Parties shall have
any further obligations or Liabilities under, or with respect to, this Agreement. Notwithstanding the foregoing or anything to
the contrary in this Agreement, (i) the termination of this Agreement pursuant to Section 5(b) shall not
affect any Liability on the part of any Party for a Willful Breach of any covenant or agreement set forth in this Agreement prior
to such termination or Fraud, (ii) Section 2(a)(i) (solely to the extent that it relates to Section 5.3(a) (Confidentiality)
of the Business Combination Agreement) and the representations and warranties set forth in Sections 3(g) and (h) shall
each survive any termination of this Agreement, (iii) Section 2(a)(i) (solely to the extent that it relates
to Section 5.4(a) (Public Announcements) of the Business Combination Agreement) shall survive the termination of this
Agreement pursuant to Section 5(a) and (iv) Section 2(a)(ii) (solely to the extent that
it relates to Section 8.18 (Trust Account Waiver) of the Business Combination Agreement) shall survive the termination of
this Agreement pursuant to Section 5(b). For purposes of this Section 5, (x) “Willful Breach”
means a material breach that is a consequence of an act undertaken or a failure to act by the breaching Party with the knowledge
that the taking of such act or such failure to act would, or would reasonably be expected to, constitute or result in a breach
of this Agreement and (y) “Fraud” means an act or omission committed by a Party, and requires: (A) a
false or incorrect representation or warranty expressly set forth in this Agreement, (B) with actual knowledge (as opposed
to constructive, imputed or implied knowledge) by the Party making such representation or warranty that such representation or
warranty expressly set forth in this Agreement is false or incorrect, (C) an intention to deceive another Party, to induce
him, her or it to enter into this Agreement, (D) another Party, in justifiable or reasonable reliance upon such false or
incorrect representation or warranty expressly set forth in this Agreement, causing such Party to enter into this Agreement, and
(E) another Party to suffer damage by reason of such reliance. For the avoidance of doubt, “Fraud” does not include
any claim for equitable fraud, promissory fraud, unfair dealings fraud or any torts (including a claim for fraud or alleged fraud)
based on negligence or recklessness.


 


6.            Fiduciary
Duties. Notwithstanding anything in this Agreement to the contrary, (a) no Stockholder makes any agreement or understanding
herein in any capacity other than in such Stockholder’s capacity as a record holder and beneficial owner of its Subject
Company Shares and not in any other capacity and (b) nothing herein will be construed to limit or affect any action or inaction
by any representative or Affiliate of such Stockholder serving as a member of the board of directors of any Group Company or as
an officer, employee or fiduciary of any Group Company, in each case, acting in such person’s capacity as a director, officer,
employee or fiduciary of such Group Company.


 


7.            No
Recourse. Except for claims pursuant to the Business Combination Agreement or any other Ancillary Document by any party(ies)
thereto against any other party(ies) thereto, each Party agrees that (a) this Agreement may only be enforced against, and
any action for breach of this Agreement may only be made against, the Parties, and no claims of any nature whatsoever (whether
in tort, contract or otherwise) arising under or relating to this Agreement, the negotiation hereof or its subject matter, or
the transactions contemplated hereby shall be asserted against the Company or any Company Non-Party Affiliate (other than any
Stockholder named as a party hereto, on the terms and subject to the conditions set forth herein) or any Longview Non-Party Affiliate,
and (b) none of the Company, any Company Non-Party Affiliates (other than any Stockholder named as a party hereto, on the
terms and subject to the conditions set forth herein) or any Longview Non-Party Affiliate shall have any Liability arising out
of or relating to this Agreement, the negotiation hereof or its subject matter, or the transactions contemplated hereby, including
with respect to any claim (whether in tort, contract or otherwise) for breach of this Agreement or in respect of any written or
oral representations made or alleged to be made in connection herewith, as expressly provided herein, or for any actual or alleged

relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement, in each case,
without posting a bond or undertaking and without proof of damages and this being in addition to any other remedy to which they
are entitled at law or in equity. Each Party agrees that it will not oppose the granting of an injunction, specific performance
and other equitable relief when expressly available pursuant to the terms of this Agreement on the basis that the other parties
have an adequate remedy at law or an award of specific performance is not an appropriate remedy for any reason at law or equity.


 


13.          No
Third Party Beneficiaries. This Agreement shall be for the sole benefit of the Parties and their respective successors and
permitted assigns and is not intended, nor shall be construed, to give any Person, other than the Parties and their respective
