Forbearance
Agreement and


Third
Amendment to Credit Agreement
and Guaranty


 


This Forbearance Agreement
and Third Amendment to Credit Agreement and Guaranty (herein, this “Agreement”) is entered into as of February
12, 2020, by and among Icagen-T, Inc., a Delaware corporation (the “Borrower”), Icagen, Inc., a Delaware corporation
(“Parent”), the Subsidiary Guarantors party thereto (together with the Parent, the “Guarantors”,
and the Guarantors together with the Borrower, collectively, the “Loan Parties”), each financial institution
from time to time party hereto as lender (each, a “Lender” and collectively, the “Lenders”),
and Perceptive Credit Holdings II, LP, as administrative agent for the Lenders (in such capacity, and together with its successors
and assigns, the “Agent”).


 


R
e c i t a l s:


 


A. The Lenders
have extended credit to the Borrower on the terms and conditions set forth in that certain Credit Agreement and Guaranty, dated
as of August 31, 2018 (as amended by that certain Forbearance Agreement and First Amendment to Credit Agreement and Guaranty dated
as of August 27, 2019, and that certain Forbearance Agreement and Second Amendment to Credit Agreement and Guaranty dated as of
January 13, 2020, the “Existing Credit Agreement”; the Existing Credit Agreement as amended by this Agreement,
the “Credit Agreement”).


 


B. The Loan Parties
are not in compliance with the financial covenant set forth in Section 10.01 of the Existing Credit Agreement and the affirmative
covenants set forth in Sections 8.01(a) and (d) and Section 8.24 of the Existing Credit Agreement, resulting in Events of Default
under Sections 11.01(d) and (e), respectively, of the Existing Credit Agreement (collectively with all other Events of Default
existing and continuing on the date hereof the “Existing Defaults”).


 


C. The Lenders
are not willing to waive the Existing Defaults, but during and only during the period (the “Standstill Period”)
beginning on the date of this Agreement and ending on the date of the Standstill Termination (as defined below), the Lenders are
willing to temporarily forbear from exercising certain rights and remedies available solely by reason of the Existing Defaults
on the terms and conditions set forth in this Agreement and the Credit Agreement.


 


D. The parties
hereto agree to amend the Existing Credit Agreement pursuant to the terms of this Agreement.


 


Now,
Therefore, for good and valuable consideration,
the receipt and sufficiency of which is hereby acknowledged, the parties hereto agree as follows:


 


1. Incorporation
of Recitals; Defined Terms. The parties hereto acknowledge that the Recitals set forth above are true and correct in all material
respects. The defined terms in the Recitals set forth above are hereby incorporated into this Agreement by reference. All other
capitalized terms used herein without definition shall have the same meanings herein as such terms have in the Credit Agreement.


 




     


     


    


 


2. Acknowledgment
of Defaults. The Existing Defaults constitute Events of Default under the Credit Agreement. The Loan Parties acknowledge that,
because of the Existing Defaults, the Agent and the Lenders are permitted and entitled (i) under Section 11.02 of the Credit Agreement
and under the other Loan Documents to accelerate the Obligations, to enforce Liens granted under the Security Documents, and to
exercise any other rights or remedies that may be available under the Loan Documents or under applicable law and (ii) to charge
the Default Rate under Section 3.02(b) of the Credit Agreement. The Loan Parties represent to the Agent and the Lenders that there
are no Defaults or Events of Default other than the Existing Defaults.


 


3. Forbearance.
Unless and until a Standstill Termination occurs, the Agent and the Lenders party hereto will not accelerate the Obligations or
enforce any of the Liens granted under the Security Documents or exercise any other rights or remedies available solely by reason
of the Existing Defaults.


 


4. Principal
Payments. The Borrower shall pay all principal on the Closing Date Term Loan when due, including, without limitation, the
Borrower shall continue to make all scheduled payments of principal on the Term Loans as and when due under the Credit Agreement.


 


5. Interest
and Fee Payments. The Borrower shall pay all interest, fees, and other Obligations as and when due under the Credit Agreement.


 


6. Standstill
Termination. As used in this Agreement, “Standstill Termination” shall mean the earlier of October 15,
2020 or the occurrence of any one or more of the following events: (a) any Default or Event of Default under the Credit Agreement,
in each case other than the Existing Defaults; (b) any failure by any Loan Party for any reason to comply with any term, condition,
or provision contained in this Agreement; (c) any representation made by any Loan Party in this Agreement or pursuant to it proves
to be incorrect or misleading in any material respect when made (other than to the extent such representation is incorrect as
a result of the Existing Defaults); or (d) any Material Adverse Effect shall occur as determined in good faith by the Agent. The
occurrence of any Standstill Termination shall be deemed an Event of Default under the Credit Agreement. Upon the occurrence of
a Standstill Termination, the Standstill Period shall automatically terminate and the Agent and the Lenders shall then be permitted
and entitled under Section 11.02 of the Credit Agreement and the other Loan Documents, among other things, to accelerate the Obligations
and to exercise any other rights and remedies that may be available under the Loan Documents or applicable law.


 


7. Third Amendment
to Existing Credit Agreement. Upon satisfaction of the conditions set forth in Section 13 hereof, the Loan Parties, the Agent
and the Lenders hereby agree that the Existing Credit Agreement is hereby amended by incorporating the changes shown on the marked
copy of the Existing Credit Agreement attached hereto as Annex A. Deletions of text in the Existing Credit Agreement as amended
hereby are indicated by struck-through red text, and insertions of text as amended hereby are indicated by underlined blue text.
Attached hereto as Annex B is a clean copy of the Credit Agreement conformed through the Third Amendment.

8. No Waiver
and Reservation of Rights. The Loan Parties acknowledge that the Lenders are not waiving the Existing Defaults but, are simply
agreeing to forbear from exercising their rights with respect to the Existing Defaults to the extent expressly set forth in this
Agreement. Without limiting the generality of the foregoing, the Loan Parties acknowledge and agree that immediately upon expiration
of the Standstill Period, the Agent and the Lenders have all of their rights and remedies with respect to the Existing Defaults
to the same extent, and with the same force and effect, as if the forbearance had not occurred. The Loan Parties will not assert
and hereby forever waive any right to assert that the Agent or the Lenders are obligated in any way to continue beyond the Standstill
Period to forbear from enforcing their rights or remedies or that the Agent and the Lenders are not entitled to act on the Existing
Defaults after the occurrence of a Standstill Termination as if such default had just occurred and the Standstill Period had never
existed. The Loan Parties acknowledge that the Agent and the Lenders have made no representations as to what actions, if any,
the Agent or the Lenders will take after the Standstill Period or upon the occurrence of any Standstill Termination, a Default
or Event of Default, and the Agent and the Lenders must and do hereby specifically reserve any and all rights, remedies, and claims
they have (after giving effect hereto) with respect to the Existing Defaults and each other Default or Event of Default that may
occur.


 


9. Acknowledgement
of Liens and Affirmation of Guarantee. The Loan Parties hereby acknowledge and agree that the Obligations owing to the Agent
and the Lenders arising out of or in any manner relating to the Loan Documents shall continue to be secured by the Liens granted
as security therefor in the Loan Documents, to the extent provided for in the Loan Documents heretofore executed and delivered
by the such Loan Parties; and nothing herein contained shall in any manner affect or impair the priority of the Liens created
and provided for thereby as to the indebtedness, obligations, and liabilities which would be secured thereby prior to giving effect
to this Agreement. The Parent and Subsidiary Guarantors hereby reaffirm the Guaranteed Obligations owing to the Agent and the
Lenders to the extent provided for in the Credit Agreement, and hereby acknowledge and agree that nothing herein contained shall
in any manner affect or impair the Guaranteed Obligations.


 


10. Release.




  


(a) For
value received, including without limitation, the
agreements of the Lenders in this Agreement,
each Loan Party,
on behalf of itself and its successors and assigns, and
its current and former shareholders, members, parents,
subsidiaries, divisions, affiliates,
directors, officers, employees,
agents, attorneys, advisors,
consultants, and other representatives (collectively,
the “Releasing Parties”),
hereby absolutely, unconditionally,
and irrevocably releases and forever discharges the Agent
and the Lenders, and their current
and former shareholders, members, parents,
subsidiaries, divisions, affiliates,
directors, officers, employees,
agents, attorneys, advisors,
consultants, and other representatives (collectively,
the “Released Parties”)
of and from any and all claims (including,
without limitation, all counterclaims,
crossclaims, defenses, rights
of set-off and recoupment), actions,
causes of action, acts and omissions,
controversies, demands, suits,
and other liabilities (collectively,
the “Claims”) of
every kind or nature whatsoever, both in law and in equity, known


    






    -3-


     


    

 


or unknown, which any Releasing Party
has or ever had against the Released Parties
prior to, through, and including this
date, including, without limitation,
Claims arising out of the existing financing arrangements between the Borrower
and the Lenders and any Claim of breach
of the duty of good faith and fair dealing based on, among other things,
the Released Parties’
exercise of discretion under the Loan Documents.
The Loan Parties
hereby represent and warrant that, on behalf of themselves and their successors,
assigns and legal representatives, they have
not sold, conveyed, assigned,
pledged, hypothecated, or
otherwise encumbered all or any part of the Claims released in this Section.
The Loan Parties
hereby acknowledge and agree that, on behalf of themselves and their successors,
assigns and legal representatives, the Released
Parties have at all times acted in good faith with regard to the consummation and
administration of the Loan Documents.
Each Loan Party
acknowledges and agrees that, as of the date hereof, it
does not have any Claim against the Released
Parties, each of which such Loan
Party, on behalf of itself and its
successors, assigns and legal representatives, hereby
expressly waives. Each Loan Party
hereby confirms that the foregoing waiver and release is an informed waiver and release and is being freely given.


 


(B) Each
Loan Party further agrees,
on behalf of itself and its successors, assigns,
and legal representatives, not to commence,
institute, or prosecute any lawsuit,
action or other proceeding, whether judicial,
administrative or otherwise, to collect or
enforce any Claim released herein. If
any Loan Party or any of its successors,
assigns, or legal representatives violates
the foregoing covenant, the Loan Parties
hereby agree, on behalf of themselves and their successors and assigns, to
jointly and severally pay, in addition to any damages as any Released
Party may sustain as a result of such violation, all
attorneys’ fees and costs incurred by any Released
party as a result of such violation.






  


11. Entire
Agreement; Loan Documents Remain Effective; No Novation; and Modifications. This Agreement and the Loan Documents are intended
by the Agent and the Lenders as a final expression of their agreement and are intended as a complete and exclusive statement of
the terms and conditions of that agreement. This Agreement supersedes all prior agreements, whether written or oral, between the
parties with respect to its subject matter and constitutes a complete and exclusive statement of the terms of the agreement between
the parties with respect to its subject matter. Except as expressly set forth in this Agreement, the Loan Documents and all of
the obligations of the Loan Parties thereunder, the rights and benefits of the Agent and the Lenders thereunder, and the Liens
created thereby remain in full force and effect. This Agreement is not a novation nor is it to be construed as a release, waiver
or modification of any of the terms, conditions, representations, warranties, covenants, rights or remedies set forth in the Loan
Documents, except as specifically set forth herein. Without limiting the foregoing, the Loan Parties agree to comply with all
of the terms, conditions, and provisions of the Loan Documents except to the extent such compliance is irreconcilably inconsistent
with the express provisions of this Agreement. This Agreement may not be amended, supplemented, or otherwise modified except by
a written agreement entered into in


   






    -4-


     


    

 


accordance with Section 14.04 of the Credit Agreement. This
Agreement represents the final agreement between the parties and may not be contradicted
by evidence of prior, contemporaneous or subsequent oral agreements of the parties.
There are no unwritten oral agreements between the parties.


 


12. Fees and
Expenses. The Borrower shall also pay all fees and expenses (including attorneys’ fees and expenses) incurred by the
Agent and its counsel outstanding as of the date hereof.


 


13. Conditions
Precedent. The effectiveness of this Agreement is subject to the satisfaction of the following conditions precedent:


 


13.1. The Agent
and the Lenders shall have received executed counterparts of this Agreement duly executed and delivered by each Loan Party.


 


13.2. The Agent,
the Lenders and the Obligors shall have entered into a forbearance agreement and amendment to the Parent Credit Agreement and
the Agent and the Lenders shall have received an executed copy thereof, duly executed and delivered by each Loan Party.


 


14. Miscellaneous.
By its acceptance hereof, each Loan Party hereby represents that it has the necessary power and authority to execute, deliver,
and perform the undertakings contained herein, and that this Agreement constitutes the valid and binding obligation of such Loan
Party enforceable against it in accordance with its terms. Any provision of this Agreement held invalid, illegal, or unenforceable
in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity, illegality, or unenforceability
without affecting the validity, legality, and enforceability of the remaining provision hereof; and the invalidity of a particular
provision in a particular jurisdiction shall not invalidate such provision in any other jurisdiction. The parties hereto hereby
acknowledge and agree that this Agreement shall constitute a Loan Document for all purposes of the Credit Agreement and the other
Loan Documents. Unless otherwise expressly stated herein, the provisions of this Agreement shall survive the termination of the
Standstill Period. This Agreement may be executed in counterparts and by different parties on separate counterpart signature pages,
each of which constitutes an original and all of which taken together constitute one and the same instrument. Delivery of a counterpart
hereof by facsimile transmission or by e-mail transmission of an Adobe portable document format file (also known as a “PDF”
file) shall be effective as delivery of a manually executed counterpart hereof. The provisions contained in Sections 14.09 (Governing
Law), 14.10 (Jurisdiction; Service of Process and Venue) and 14.11 (Waiver of Jury Trial) of the Credit Agreement are incorporated
herein by reference, mutatis mutandis.

in Law Generally. If, on or after the date hereof, the adoption of any Law, or any change in any Law, or any change in the

has or would have the effect of reducing the rate of return on capital of a Lender (or its parent) as a consequence of a Lender’s
obligations hereunder or the Term Loan to a level below that which a Lender (or its parent) could have achieved but for such adoption,
change, request or directive by an amount reasonably deemed by it to be material, then the Borrower shall pay to such Lender on
demand such additional amount or amounts as will compensate such Lender (or its parent) for such reduction.

of such Lender, avoid the need for, or reduce the amount of, such compensation and (y) will not, in the reasonable judgment of
such Lender, be materially disadvantageous to such Lender. A certificate of such Lender claiming compensation under this Section

adoption of or any change in any applicable Law or in the interpretation or application thereof by any competent Governmental Authority
shall make it unlawful for a Lender or its lending office to make or maintain the Term Loan by such Lender (and, in the opinion
of such Lender, the designation of a different lending office would either not avoid such unlawfulness or would be disadvantageous
to such Lender), then such Lender shall promptly notify the Borrower thereof, following which (i) such Lender’s Commitment
shall be suspended until such time as such Lender may again make and maintain the Term Loan hereunder and (ii) if such Law shall
so mandate, the Term Loan shall be prepaid by the Borrower on or before such date as shall be mandated by such Law in an amount

Withholding Agent shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld
to the relevant Governmental Authority in accordance with applicable Law and, if such Tax is an Indemnified Tax, then the sum payable
by such Obligor shall be increased as necessary so that after such deduction or withholding has been made (including such deductions
and withholdings applicable to additional sums payable under this Section 5.03) the applicable Recipient receives an amount equal
to the sum it would have received had no such deduction or withholding been made.


 


(b) Payment
of Other Taxes by the Borrower. The Borrower shall timely pay to the relevant Governmental Authority in accordance with applicable
Law, or at the option of the Administrative Agent, timely reimburse it for the payment of, Other Taxes.


 


(c) Evidence
of Payments. As soon as reasonably practicable after any payment of Taxes by the Borrower to a Governmental Authority pursuant

(d) Indemnification
by the Borrower. The Borrower shall reimburse and indemnify each Recipient, within ten (10) days after demand therefor, for
the full amount of any Indemnified Taxes (including Indemnified Taxes imposed or asserted on or attributable to amounts payable
under this Section 5.03) payable or paid by such Recipient or required to be withheld or deducted from a payment to such Recipient
and any reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or
legally imposed or asserted by the relevant Governmental Authority. A certificate as to the amount of such payment or liability
delivered to the Borrower by a Lender (with a copy to the Administrative Agent), or by the Administrative Agent on its own behalf
or on behalf of a Lender, shall be conclusive absent manifest error.


 


(e) Indemnification
by the Lender. Each Lender shall severally indemnify the Administrative Agent, within 10 days after demand therefor, for (i)
any Indemnified Taxes attributable to such Lender (but only to the extent that the Borrower has not already indemnified the Administrative
Agent for such Indemnified Taxes and without limiting the obligation of the Borrower to do so), and (ii) any Taxes attributable
to such Lender, in each case, that are payable or paid by the Administrative Agent in connection with any Loan Document, and any
reasonable expenses arising therefrom or with respect thereto, whether or not such Taxes were correctly or legally imposed or asserted
by the relevant Governmental Authority. A certificate as to the amount of such payment or liability delivered to any Lender by
the Administrative Agent shall be conclusive absent manifest error. Each Lender hereby authorizes the Administrative Agent to set
off and apply any and all amounts at any time owing to such Lender under any Loan Document or otherwise payable by the Administrative
Agent to such Lender from any other source against any amount due to the Administrative Agent under this paragraph (e).


 


(f) Status
of Lenders. (i) Any Lender that is entitled to an exemption from or reduction of withholding Tax with respect to payments made
under any Loan Document shall deliver to the Borrower and the Administrative Agent, at the time or times prescribed by applicable
Law or reasonably requested by the Borrower or the Administrative Agent, such properly completed and executed documentation reasonably
requested by the Borrower or the Administrative Agent as will permit such payments to be made without withholding or at a reduced
rate of withholding. In addition, any Lender shall deliver such other documentation prescribed by Law or reasonably requested by
the Borrower or the Administrative Agent as will enable the Borrower or the Administrative Agent to determine whether or not such
Lender is subject to backup withholding or information reporting requirements. Notwithstanding anything to the contrary in the
preceding two sentences, the completion, execution and submission of such documentation (other than such documentation set forth
in Section 5.03(f)(ii)(A), (ii)(B), and (ii)(D)) shall not be required if in such Lender’s reasonable judgment such completion,
execution or submission would subject such Lender to any material unreimbursed cost or expense or would materially prejudice the
legal or commercial position of such Lender.

 (ii) Without limiting the generality of the foregoing:




 


(A) any
Lender (or, if the Lender is a disregarded entity for U.S. federal income tax purposes, the Person treated as the owner of the
assets of such Lender for U.S. federal income Tax purposes) that is a U.S. Person shall deliver to the Borrower and the Administrative
Agent on or prior to the date on which such Lender becomes a Lender under this Agreement (and from time to time thereafter upon
the reasonable request of the Borrower or the Administrative Agent), executed copies of IRS Form W-9 (or successor form) certifying
that such Lender is exempt from U.S. federal backup withholding Tax;


 


(B) any
Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such
number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender
under this Agreement (and from time to time thereafter upon the reasonable request of the Borrower and the Administrative Agent),
whichever of the following is applicable:


 


(1) in
the case of a Foreign Lender claiming the benefits of an income tax treaty to which the United States is a party (x) with respect
to payments of interest under any Loan Document, executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E as applicable (or successor
forms) establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the “interest” article
of such tax treaty and (y) with respect to any other applicable payments under any Loan Document, IRS Form W-8BEN or IRS Form W-8BEN-E
as applicable (or successor forms) establishing an exemption from, or reduction of, U.S. federal withholding Tax pursuant to the
“business profits” or “other income” article of such tax treaty;


 


 (2) executed copies of IRS Form W-8ECI (or successor form);




 


(3) in
the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under Section 881(c) of the Code, (x)

the meaning of Section 881(c)(3)(A) of the Code, a “10 percent shareholder” of the applicable the Borrower within
the meaning of Section 881(c)(3)(B) of the Code, or a “controlled foreign corporation” described in Section 881(c)(3)(C)
of the Code (a “U.S. Tax Compliance Certificate”) and (y) executed copies of IRS Form W-8BEN or IRS Form W-8BEN-E
as applicable (or successor forms); or


 


(4) to
the extent a Foreign Lender is not the beneficial owner, executed copies of IRS Form W-8IMY (or successor form), accompanied by
IRS Form W-8ECI (or successor form), IRS Form W-8BEN (or successor form), IRS Form W-8BEN-E, a U.S. Tax Compliance Certificate,

beneficial owner, as applicable; provided that if the Foreign Lender is a partnership and one (1) or more direct or indirect
partners of such Foreign Lender are claiming the portfolio interest exemption, such Foreign Lender may provide a U.S. Tax Compliance
Certificate substantially in the form of Exhibit D-4 on behalf of each such direct and indirect partner.


 






    -37-


     


    

 


(C) any
Foreign Lender shall, to the extent it is legally entitled to do so, deliver to the Borrower and the Administrative Agent (in such
number of copies as shall be requested by the recipient) on or prior to the date on which such Foreign Lender becomes a Lender
under this Agreement (and from time to time thereafter at the time or times prescribed by applicable Law or upon the reasonable
request of the Borrower or the Administrative Agent), executed copies of any other form prescribed by applicable Law as a basis
for claiming exemption from or a reduction in U.S. federal withholding Tax, duly completed, together with such supplementary documentation
as may be prescribed by applicable Law to permit the Borrower or the Administrative Agent to determine the withholding or deduction
required to be made; and


 


(D) if
a payment made to a Lender under any Loan Document would be subject to U.S. federal withholding Tax imposed by FATCA if such Lender
were to fail to comply with the applicable reporting requirements of FATCA (including those contained in Section 1471(b) or 1472(b)
of the Code, as applicable), such Lender shall deliver to the Borrower and the Administrative Agent at the time or times prescribed
by Law and at such time or times as reasonably requested by the Borrower or the Administrative Agent such documentation prescribed
by applicable Law (including as prescribed by Section 1471(b)(3)(C)(i) of the Code) and such additional documentation reasonably
requested by the Borrower or the Administrative Agent as may be necessary for the Borrower and the Administrative Agent to comply
with their obligations under FATCA and to determine that such Lender has complied with such Lender’s obligations under FATCA
or to determine the amount to deduct and withhold from such payment. Solely for purposes of this clause (D), “FATCA”
shall include any amendments made to FATCA after the date of this Agreement.


 


Each Lender agrees that
if any form or certification it previously delivered expires or becomes obsolete or inaccurate in any respect, it shall update
such form or certification or promptly notify the Borrower and the Administrative Agent in writing of its legal inability to do
so.


 


(g) Treatment
of Certain Tax Benefits. If any party to this Agreement determines, in its sole discretion exercised in good faith, that it
has received a refund of any Taxes as to which it has been indemnified pursuant to this Section 5.03 (including by the payment
of additional amounts pursuant to this Section 5.03), it shall pay to the indemnifying party an amount equal to such refund (but
only to the extent of indemnity payments made under this Section 5.03 with respect to the Taxes giving rise to such refund), net
of all out-of-pocket expenses (including Taxes) of such indemnified party and without interest (other than any interest paid by
the relevant Governmental Authority with respect to such refund). Such indemnifying party, upon the request of such indemnified
party, shall repay to such indemnified party the amount paid over pursuant to this paragraph (plus any penalties, interest or
other charges imposed by the relevant Governmental Authority) in the event that such indemnified party is required to repay such
refund to such Governmental Authority. Notwithstanding anything to the contrary in this Section 5.03(g), in no event will the
indemnified party be required to pay any amount to an indemnifying party pursuant to this Section 5.03(g) the payment of which
would place the indemnified party in a less favorable net after-Tax position than the indemnified party would have been in if
the Tax subject to indemnification and giving rise to such refund had not been deducted, withheld or otherwise imposed and the
indemnification payments or additional amounts with respect to such Tax had never been paid. This Section 5.03(g) shall not be
construed to require any indemnified party to make available its Tax returns (or any other information relating to its Taxes that
it deems confidential) to the indemnifying party or any other Person.


 






    -38-


     


    

 


(h) Designation
of a Different Lending Office. If the Borrower is required to pay any Indemnified Taxes or additional amounts to any Lender
or to any Governmental Authority for the account of any Lender pursuant to Section 5.01 or this Section 5.03, then such Lender
shall (at the request of the Borrower) use commercially reasonable efforts to designate a different lending office for funding
or booking its Term Loan hereunder or to assign and delegate its rights and obligations hereunder to another of its offices, branches
or Affiliates if, in the sole reasonable judgment of such Lender, such designation or assignment and delegation would (i) eliminate
or reduce amounts payable pursuant to Section 5.01 or this Section 5.03, as the case may be, in the future, (ii) not subject such
Lender to any unreimbursed cost or expense and (iii) not otherwise be disadvantageous to such Lender. The Borrower hereby agrees
to pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment and delegation.


 


(i) Survival.
Each party’s obligations under this Section 5 shall survive the resignation or replacement of the Administrative Agent or
any assignment of rights by, or the replacement of, a Lender, the termination of the Commitments and the repayment, satisfaction
or discharge of all Obligations under any Loan Document.


 


Section
5.04. Delay in Requests. Failure or delay on the part of any Lender to demand compensation pursuant to this Section 5 shall
not constitute a waiver of such Lender’s right to demand such compensation; provided that the Borrower shall not be
required to compensate a Lender pursuant to this Section for any increased costs incurred or reductions suffered more than six-months
prior to the date that such Lender notifies the Borrower of the change in Law giving rise to such increased costs or reductions,
and of such Lender’s intention to claim compensation therefor (except that, if the change in Law giving rise to such increased
costs or reductions is retroactive, then the sixth-month period referred to above shall be extended to include the period of retroactive
effect thereof).

(ii) has all requisite corporate or other organizational power, and has all Governmental Approvals necessary to own its assets

default under (x) any Material Agreement or (y) any Contract creating or evidencing any Material Indebtedness or

the Obligors has violated, infringed, diluted or misappropriated or, by conducting its business as currently conducted or as proposed
to be conducted does or would violate, infringe, dilute or misappropriate any Intellectual Property of another, and to Obligors’
knowledge, there is no basis for such an allegation.

Material Intellectual Property invalid that has not been disclosed to the United States Patent and Trademark Office.


 


(xi) All
maintenance fees, annuities, and the like due or payable on the Patents have been timely paid or the failure to so pay was the

unenforceable and, to Obligors’ knowledge, neither they nor any current or prior owner of such Patents or their respective
agents or representatives, have engaged in any conduct, or omitted to perform any necessary act, the result of which would invalidate
or render unpatentable or unenforceable any such Patent.


 


(xiv) To
Obligors’ knowledge, other than as set forth in Schedule 7.05(b), Obligors are not obligated to make any payment by way of
royalties, fees or otherwise to any owner or licensee of, or other claimant to, any Obligor Intellectual Property, with respect
to the use thereof or in connection with the conduct of its business or otherwise.

Obligors’ knowledge, no employee of Obligors is or has been in violation of any term of any employment contract, patent disclosure
agreement, invention assignment agreement, non-competition agreement, non-solicitation agreement, nondisclosure agreement or any
restrictive covenant to or with a former employer where the basis of such violation relates to such employee’s employment
with Obligors.


 


(xvi) Each

not so declared to be due and payable may thereafter be declared to be due and payable), and thereupon the principal of the Term
Loan so declared to be due and payable, together with accrued interest thereon and all fees and other Obligations, shall become
due and payable immediately (in the case of the Term Loan, at the Prepayment Price therefor), without presentment, demand, protest
or other notice of any kind, all of which are hereby waived by each Obligor; and in case of an Event of Default described in Section
11.01(i), the principal of the Term Loan then outstanding, together with accrued interest thereon and all fees and other Obligations,
shall automatically become due and payable immediately (in the case of the Term Loan, at the Prepayment Price therefor), without
presentment, demand, protest or other notice of any kind, all of which are hereby waived by each Obligor.


 


Section

amount thereunder) and otherwise exercise any and all rights of such Obligor or Subsidiary, as the case may be, thereunder, as
may be necessary to prevent or cure any default and (b) without limiting the foregoing, upon any such default, each Obligor shall
promptly execute, acknowledge and deliver to the Lenders such instruments as may reasonably be required of such Obligor to permit
the Lenders to cure any default under the applicable Material Agreement or permit the Lenders to take such other action required
to enable the Lenders to cure or remedy the matter in default and preserve the interests of the Lenders. Any amounts paid by the
Lenders pursuant to and in accordance with this Section 11.03 shall be payable on demand by the Obligors, shall accrue interest
at the Default Rate if not paid on demand and shall constitute “Obligations”.


 






    -76-


     


    

 


In furtherance of and in no
way limiting the foregoing, each of the authorized representatives of the Administrative Agent is hereby irrevocably made, constituted
and appointed the true and lawful attorney for Borrower and the other Obligors (without requiring any of them to act as such)
with full power of substitution after the occurrence and during the continuance of an Event of Default to advance funds in excess
of the Commitments to pay all amounts necessary under the Sanofi Documents in order to release Sanofi’s lien on the Mortgaged
Premises and to terminate the S/I Deed of Trust and the S/I Warranty and Reverter Deed; it being understood and agreed that this
power of attorney in this Section 11.03 shall be a power coupled with an interest and cannot be revoked. All amounts advanced
by the Administrative Agent or any Lender on behalf of the Administrative Agent pursuant to this Section 11.03 shall automatically
and without further action be added to the outstanding principal amount of the Term Loan and shall be a “Term Loan”
for purposes of this Agreement and the other Loan Documents.


 


Section 11.04. Prepayment
Premium and Prepayment Price. For the avoidance of doubt, (x) the applicable Prepayment Premium (as a component of the
Prepayment Price) shall be due and payable at any time the Closing Date Term Loan becomes due and payable in full prior to the
Maturity Date in accordance with the terms hereof, (y) the Exit Fee shall be due and payable at any time the First Amendment Term
Loan becomes due and payable in full prior to the First Amendment Maturity Date in accordance with the terms hereof, and (z) the
Second Amendment Exit Fee shall be due and payable at any time the First Amendment Term Loan becomes due and payable in full prior
to the Second Amendment Maturity Date in accordance with the terms hereof, in the case of each of clause (x), (y) and (z) above,
whether due to acceleration pursuant to the terms of this Agreement (in which case it shall be due immediately, upon the giving
of notice to the Borrower or automatically by operation of law or otherwise in accordance with Section 11.02) (including, without
limitation, on account of any bankruptcy filing). In view of the impracticability and extreme difficulty of ascertaining the actual
amount of damages to the Lenders or profits lost by the Lenders as a result of such acceleration, and by mutual agreement of the
parties as to a reasonable estimation and calculation of the lost profits or damages of the Lenders, the Prepayment Premium, the
Exit Fee and the Second Amendment Exit Fee, as applicable, shall be due and payable upon such date. Each Obligor hereby waives
any defense to payment, whether such defense may be based in public policy, ambiguity, or otherwise. The Obligors and the Lenders
acknowledge and agree that any Prepayment Premium, Exit Fee or Second Amendment Exit Fee due and payable in accordance with this
Agreement shall not constitute unmatured interest, whether under Section 5.02(b)(3) of the Bankruptcy Code or otherwise. Each
Obligor further acknowledges and agrees, and waives any argument to the contrary, that payment of such amount does not constitute
a penalty or an otherwise unenforceable or invalid obligation.


 


Section
12. Guarantee.


 


Section 12.01. The
Guarantee. Parent and the Subsidiary Guarantors hereby jointly and severally guarantee to the Administrative Agent and the
Lenders, and their successors and assigns, the prompt payment in full when due (whether at stated maturity, by acceleration or

to the Administrative Agent and the Lenders by the Borrower and each other Obligor under this Agreement or under any other Loan
Document, in each case strictly in accordance with the terms hereof and thereof (such obligations being herein collectively called
the “Guaranteed Obligations”). Parent and the Subsidiary Guarantors hereby further jointly and severally agree
that if the Borrower or any other Obligor shall fail to pay in full when due (whether at stated maturity, by acceleration or otherwise)
any of the Guaranteed Obligations, Parent and the Subsidiary Guarantors will promptly pay the same, without any demand or notice
whatsoever, and that in the case of any extension of time of payment or renewal of any of the Guaranteed Obligations, the same
will be promptly paid in full when due (whether at extended maturity, by acceleration or otherwise) in accordance with the terms
of such extension or renewal.

Section
12.02. Obligations Unconditional. The obligations of Parent and the Subsidiary Guarantors under Section 12.01 are absolute
and unconditional, joint and several, irrespective of the value, genuineness, validity, regularity or enforceability of the obligations
of the Borrower under this Agreement or any other agreement or instrument referred to herein, or any substitution, release or exchange
of any other guarantee of or security for any of the Guaranteed Obligations, and, to the fullest extent permitted by Law, irrespective
of any other circumstance whatsoever that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Section 12.02 that the obligations of Parent and the Subsidiary Guarantors hereunder shall be absolute
and unconditional, joint and several, under any and all circumstances. Without limiting the generality of the foregoing, it is
agreed that the occurrence of any one or more of the following shall not alter or impair the liability of Parent or the Subsidiary
Guarantors hereunder, which shall remain absolute and unconditional as described above:

any time or from time to time, without notice to Parent or the Subsidiary Guarantors, the time for any performance of or compliance
with any of the Guaranteed Obligations shall be extended, or such performance or compliance shall be waived;


 


(b) any
of the acts mentioned in any of the provisions of this Agreement or any other agreement or instrument referred to herein shall
be done or omitted;

maturity of any of the Guaranteed Obligations shall be accelerated, or any of the Guaranteed Obligations shall be modified, supplemented
or amended in any respect, or any right under this Agreement or any other agreement or instrument referred to herein shall be waived

in part or otherwise dealt with; or


 


(d) any
lien or security interest granted to, or in favor of, the Secured Parties as security for any of the Guaranteed Obligations shall
fail to be perfected.


 


Parent
and the Subsidiary Guarantors hereby expressly waive diligence, presentment, demand of payment, protest and all notices whatsoever,
and any requirement that the Administrative Agent or any Lender exhaust any right, power or remedy or proceed against the Borrower
under this Agreement or any other agreement or instrument referred to herein, or against any other Person under any other guarantee
of, or security for, any of the Guaranteed Obligations.

12.03. Reinstatement. The obligations of Parent and the Subsidiary Guarantors under this Section 12 shall be automatically
reinstated if and to the extent that for any reason any payment by or on behalf of the Borrower in respect of the Guaranteed Obligations
is rescinded or must be otherwise restored by any holder of any of the Guaranteed Obligations, whether as a result of any proceedings
in bankruptcy or reorganization or otherwise, and Parent and the Subsidiary Guarantors jointly and severally agree that they will
indemnify the Administrative Agent and the Lenders on demand for all reasonable costs and expenses (including fees of counsel)
incurred by such Persons in connection with such rescission or restoration, including any such costs and expenses incurred in
defending against any claim alleging that such payment constituted a preference, fraudulent transfer or similar payment under

Section
12.04. Subrogation. Parent and the Subsidiary Guarantors hereby jointly and severally agree that, until the payment and satisfaction
in full of all Guaranteed Obligations and the expiration and termination of the Commitments, they shall not exercise any right
or remedy arising by reason of any performance by them of their guarantee in Section 12.01, whether by subrogation or otherwise,
against the Borrower or any other guarantor of any of the Guaranteed Obligations or any security for any of the Guaranteed Obligations.


 


Section
12.05. Remedies. Parent and the Subsidiary Guarantors jointly and severally agree that, as between Parent and the Subsidiary
Guarantors, on one hand, and the Administrative Agent and the Lenders, on the other hand, the obligations of the Borrower under
this Agreement and under the other Loan Documents may be declared to be forthwith due and payable as provided in Section 11 (and
shall be deemed to have become automatically due and payable in the circumstances provided in Section 11) for purposes of Section
12.01 notwithstanding any stay, injunction or other prohibition preventing such declaration (or such obligations from becoming
automatically due and payable) as against the Borrower and that, in the event of such declaration (or such obligations being deemed
to have become automatically due and payable), such obligations (whether or not due and payable by the Borrower) shall forthwith
become due and payable by Parent and the Subsidiary Guarantors for purposes of Section 12.01.


 


Section
12.06. Instrument for the Payment of Money. Parent and each Subsidiary Guarantor hereby acknowledges that the guarantee in

hereunder, shall have the right to proceed by motion for summary judgment in lieu of complaint pursuant to N.Y. Civ. Prac. L&R
§ 3213.


 


Section
12.07. Continuing Guarantee. The guarantee in this Section 12 is a continuing guarantee, and shall apply to all Guaranteed
Obligations whenever arising.


 


Section
12.08. Rights of Contribution. Parent and the Subsidiary Guarantors hereby agree, as between themselves, that if Parent or
any Subsidiary Guarantor shall become an Excess Funding Guarantor (as defined below) by reason of the payment by Parent or such
Subsidiary Guarantor of any Guaranteed Obligations, Parent and/or each other Subsidiary Guarantor shall, on demand of such Excess
Funding Guarantor (but subject to the next sentence), pay to such Excess Funding Guarantor an amount equal to Parent’s or
such Subsidiary Guarantor’s Fair Share (as defined below and determined, for this purpose, without reference to the properties,
debts and liabilities of such Excess Funding Guarantor) of the Excess Payment (as defined below) in respect of such Guaranteed
Obligations. The payment obligation of Parent or a Subsidiary Guarantor to any Excess Funding Guarantor under this Section 12.08
shall be subordinate and subject in right of payment to the prior payment in full of the obligations of Parent or such Subsidiary
Guarantor under the other provisions of this Section 12 and such Excess Funding Guarantor shall not exercise any right or remedy
with respect to such excess until payment and satisfaction in full of all of such obligations.


 






    -79-


     


    

 


For purposes
of this Section 12.08, (i) “Excess Funding Guarantor” means, in respect of any Guaranteed Obligations, Parent
or a Subsidiary Guarantor that has paid an amount in excess of its Fair Share of such Guaranteed Obligations, (ii) “Excess
Payment” means, in respect of any Guaranteed Obligations, the amount paid by an Excess Funding Guarantor in excess of
its Fair Share of such Guaranteed Obligations and (iii) “Fair Share” means, for Parent or any Subsidiary Guarantor,
the ratio (expressed as a percentage) of (x) the amount by which the aggregate present fair saleable value of all properties of
Parent or such Subsidiary Guarantor (excluding any shares of stock of any other Subsidiary Guarantor) exceeds the amount of all
the debts and liabilities of Parent or such Subsidiary Guarantor (including contingent, subordinated, unmatured and unliquidated
liabilities, but excluding the obligations of Parent or such Subsidiary Guarantor hereunder and any obligations of any other Subsidiary
Guarantor that have been guaranteed by Parent or such Subsidiary Guarantor) to (y) the amount by which the aggregate fair saleable
value of all properties of all of Parent and the Subsidiary Guarantors exceeds the amount of all the debts and liabilities (including
contingent, subordinated, unmatured and unliquidated liabilities, but excluding the obligations of the Borrower, Parent and the
Subsidiary Guarantors hereunder and under the other Loan Documents) of all of Parent and the Subsidiary Guarantors, determined
(A) with respect to Parent or any Subsidiary Guarantor that is a party hereto on the Closing Date, as of the Closing Date,
and (B) with respect to any other Subsidiary Guarantor, as of the date such Subsidiary Guarantor becomes a Subsidiary Guarantor
hereunder.


 


Section
12.09. General Limitation on Guarantee Obligations. In any action or proceeding involving any provincial, territorial or state
corporate law, or any state or federal bankruptcy, insolvency, reorganization or other law affecting the rights of creditors generally,
if the obligations of Parent or any Subsidiary Guarantor under Section 12.01 would otherwise, taking into account the provisions
of Section 12.08, be held or determined to be void, invalid or unenforceable, or subordinated to the claims of any other creditors,
on account of the amount of its liability under Section 12.01, then, notwithstanding any other provision hereof to the contrary,
the amount of such liability shall, without any further action by Parent or such Subsidiary Guarantor, the Administrative Agent,
any Lender or any other Person, be automatically limited and reduced to the highest amount that is valid and enforceable and not
subordinated to the claims of other creditors as determined in such action or proceeding.


 


Section
13. Administrative Agent.


 


Section
13.01. Appointment. Each of the Lenders hereby irrevocably appoints Perceptive Credit Holdings II, LP, a Delaware limited
partnership, to act on its behalf as the Administrative Agent hereunder and under the other Loan Documents and authorizes the
Administrative Agent to take such actions on its behalf and to exercise such powers as are delegated to the Administrative Agent
by the terms hereof or thereof, together with such actions and powers as are reasonably incidental thereto. The provisions of
this Section 13 are solely for the benefit of the Administrative Agent and the Lenders, and neither the Borrower nor any other
Obligor will have rights as a third-party beneficiary of any of such provisions. It is understood and agreed that the use of the
term “agent” herein or in any other Loan Documents (or any other similar term) with reference to the Administrative
Agent is not intended to connote any fiduciary or other implied (or express) obligations arising under agency doctrine of any
applicable Law. Instead, such term is used as a matter of market custom, and is intended to create or reflect only an administrative
relationship between contracting parties.


 






    -80-


     


    

 


Section
13.02. Rights as a Lender. The Person serving as the Administrative Agent hereunder will have the same rights and powers in
its capacity as a Lender as any other Lender and may exercise the same as though it were not the Administrative Agent, and the
term “Lender” or “Lenders” will, unless otherwise expressly indicated or unless the context otherwise requires,
include the Person serving as the Administrative Agent hereunder in its individual capacity to the extent such Person is a Lender.
Such Person and its Affiliates may accept deposits from, lend money to, own securities of, act as the financial advisor or in any
other advisory capacity for, and generally engage in any kind of business with, the Borrower, the other Obligors or any other Subsidiaries
or Affiliates of the Obligors as if such Person were not the Administrative Agent hereunder and without any duty to account therefor
to the Lenders.


 


Section
13.03. Exculpatory Provisions. (a) The Administrative Agent will not have any duties or obligations except those expressly
set forth herein and in the other Loan Documents, and its duties hereunder are administrative in nature. Without limiting the generality
of the foregoing, the Administrative Agent:


 


(i) will
not be subject to any fiduciary or other implied duties, regardless of whether a Default has occurred and is continuing;


 


(ii) will
not have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers
expressly contemplated hereby or by the other Loan Documents that the Administrative Agent is required to exercise as directed
in writing by the Majority Lenders (or such other number or percentage of the Lenders as will be expressly provided for herein
or in the other Loan Documents); provided that the Administrative Agent will not be required to take any action that, in
its opinion or the opinion of its counsel, may expose the Administrative Agent to liability or that is contrary to any Loan Document
or applicable Law, including any action that may be in violation of the automatic stay under any Insolvency Proceeding; and


 


(iii) will
not, except as expressly set forth herein and in the other Loan Documents, have any duty to disclose, and will not be liable for
the failure to disclose, any information relating to the Obligors or any of its Subsidiaries or Affiliates that is communicated
to or obtained by the Person serving as the Administrative Agent or any of its Affiliates in any capacity.


 


(b) The
Administrative Agent will not be liable for any action taken or not taken by it (i) with the consent or at the request
of the Majority Lenders (or such other number or percentage of the Lenders as will be necessary, or as the Administrative
Agent believes in good faith will be necessary, under the circumstances), or (ii) in the absence of its own gross negligence
or willful misconduct as determined by a court of competent jurisdiction by final and nonappealable judgment. The
Administrative Agent will be deemed not to have knowledge of any Default unless and until notice describing such Default is
given to the Administrative Agent in writing by the Borrower or a Lender.


 






    -81-


     


    

 


(c) The
Administrative Agent will not be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation
made in or in connection with this Agreement or any other Loan Document, (ii) the contents of any certificate, report or other
document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of
the covenants, agreements or other terms or conditions set forth herein or therein or the occurrence of any Default, (iv) the validity,
enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document
or (v) the satisfaction of any condition set forth in Section 6 or elsewhere herein, other than to confirm receipt of items expressly
required to be delivered to the Administrative Agent.


 


Section
13.04. Reliance by Administrative Agent. The Administrative Agent will be entitled to rely upon, and will not incur any liability
for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing (including any electronic
message, Internet or intranet website posting or other distribution) believed by it to be genuine and to have been signed, sent
or otherwise authenticated by the proper Person. The Administrative Agent also may rely upon any statement made to it orally or
by telephone and believed by it to have been made by the proper Person, and will not incur any liability for relying thereon. In
determining compliance with any condition hereunder to the making of the Term Loan that by its terms must be fulfilled to the satisfaction
of a Lender, the Administrative Agent may presume that such condition is satisfactory to such Lender unless the Administrative
Agent has received notice to the contrary from such Lender prior to the making of such Term Loan. The Administrative Agent may
consult with legal counsel (who may be counsel for the Borrower), independent accountants and other experts selected by it, and
will not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.


 


Section
13.05. Delegation of Duties. The Administrative Agent may perform any and all of its duties and exercise its rights and powers
hereunder or under any other Loan Document by or through any one or more sub-agents appointed by the Administrative Agent. The
Administrative Agent and any such sub-agent may perform any and all of its duties and exercise its rights and powers by or through
their respective Affiliates. The exculpatory provisions of this Section will apply to any such sub-agent and to the Affiliates
of the Administrative Agent and any such sub-agent, and will apply to their respective activities in connection with the syndication
of the facility as well as activities as Administrative Agent. The Administrative Agent will not be responsible for the negligence
or misconduct of any sub-agents except to the extent that a court of competent jurisdiction determines in a final and nonappealable
judgment that the Administrative Agent acted with gross negligence or willful misconduct in the selection of such sub-agents.


 






    -82-


     


    

 


Section
13.06. Resignation of Agent. (a) The Administrative Agent may at any time give notice of its resignation to the Lenders and
the Borrower, which notice shall set forth the effective date of such resignation (the “Resignation Effective Date”),
such date not to be earlier than the thirtieth (30th) day following the date of such notice. The Majority Lenders and the Borrower
shall mutually agree upon a successor to the Administrative Agent. If the Majority Lenders and the Borrower are unable to so mutually
agree and no successor shall have been appointed within twenty-five (25) days after the retiring Administrative Agent gives notice
of its resignation, then the retiring Administrative Agent may (but will not be obligated to), on behalf of the Lenders, appoint
a successor Administrative Agent it shall designate (in its reasonable discretion after consultation with the Borrower and the
Majority Lenders). Whether or not a successor has been appointed, such resignation will become effective in accordance with such
notice on the Resignation Effective Date.


 


(b) With
effect from the Resignation Effective Date (i) the retiring Administrative Agent will be discharged from its duties and obligations
hereunder and under the other Loan Documents (except that in the case of any Collateral held by the Administrative Agent on behalf
of the Lenders under any of the Loan Documents, the retiring Administrative Agent will continue to hold such Collateral until such
time as a successor Administrative Agent is appointed) and (ii) except for any indemnity payments owed to the retiring Administrative
Agent, all payments, communications and determinations provided to be made by, to or through the Administrative Agent will instead
be made by or to each Lender directly, until such time, if any, as the Majority Lenders appoint a successor Administrative Agent
as provided for above. Upon the acceptance of a successor’s appointment as Administrative Agent hereunder, such successor
will succeed to and become vested with all of the rights, powers, privileges and duties of the retiring Administrative Agent (other
than any rights to indemnity payments owed to the retiring Administrative Agent), and the retiring Administrative Agent will be
discharged from all of its duties and obligations hereunder or under the other Loan Documents. The fees payable by the Borrower
to a successor Administrative Agent will be the same as those payable to its predecessor unless otherwise agreed between the Borrower
and such successor. After the retiring Administrative Agent’s resignation hereunder and under the other Loan Documents, the
provisions of this Section 13 and Sections 14.03 and 14.04 will continue in effect for the benefit of such retiring Administrative
Agent, its sub-agents and their respective Affiliates in respect of any actions taken or omitted to be taken by any of them while
the retiring Administrative Agent was acting as Administrative Agent.


 


Section
13.07. Non-Reliance on Administrative Agent and Other Lenders. Each Lender acknowledges that it has, independently and without
reliance upon the Administrative Agent or any other Lender or any of their Affiliates and based on such documents and information
as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges
that it will, independently and without reliance upon the Administrative Agent or any other Lender or any of their Affiliates and
based on such documents and information as it will from time to time deem appropriate, continue to make its own decisions in taking
or not taking action under or based upon this Agreement, any other Loan Document or any related agreement or any document furnished
hereunder or thereunder.

Section
13.08. Administrative Agent May File Proofs of Claim. In case of the pendency of any Insolvency Proceeding or any other judicial
proceeding relative to the Borrower, the Administrative Agent (irrespective of whether the principal of the Term Loan will then
be due and payable as herein expressed or by declaration or otherwise and irrespective of whether the Administrative Agent has
made any demand on the Borrower) will be entitled and empowered (but not obligated), by intervention in such proceeding or otherwise:


 


(a) to
file and prove a claim for the whole amount of the principal and interest owing and unpaid in respect of the Term Loan and all
other Obligations that are owing and unpaid hereunder or under any other Loan Document and to file such other documents as may
be necessary or advisable in order to have the claims of the Lenders and the Administrative Agent (including any claim for the
reasonable compensation, expenses, disbursements and advances of the Lenders and the Administrative Agent and their respective
agents and counsel and all other amounts due the Lenders and the Administrative Agent under this Agreement or any other Loan Document)
allowed in such judicial proceeding; and


 


(b) to
collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same.


 


Any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby
authorized by each Lender to make any payments of the type described above in this Section 13.08 to the Administrative Agent and,
in the event that the Administrative Agent consents to the making of such payments directly to the Lenders, to pay to the Administrative
Agent any amount due for the reasonable compensation, expenses, disbursements and advances of the Administrative Agent and its
agents and counsel, and any other amounts due the Administrative Agent under this Agreement or any other Loan Document.


 


Section 13.09. Collateral and Guaranty Matters;
Appointment of Collateral Agent. (a) Without limiting the provisions of Section 13.08, the Lenders irrevocably agree as follows:




 


(i) the
Administrative Agent is authorized, at its option and in its discretion, to release any Lien on any property granted to or held
by the Administrative Agent under any Loan Document (A) on the date when all Obligations have been satisfied in full in cash (other
than Warrant Obligations and contingent obligations as to which no claims have been asserted), (B) that is sold or otherwise disposed
of or to be sold or otherwise disposed of as part of or in connection with any sale or other disposition permitted under the Loan
Documents, or (C) subject to Sections 14.01 and 14.04, if approved, authorized or ratified in writing by the Majority Lenders;
and


 


(ii) the
Administrative Agent is authorized, at its option and discretion, to release any Subsidiary Guarantor from its obligations hereunder
if such Person ceases to be a Subsidiary as a result of a transaction permitted under the Loan Documents.


 


Upon
request by the Administrative Agent at any time, each Lender will confirm in writing the Administrative Agent’s authority
to release or subordinate its interest in particular types or items of Collateral, or to release any Subsidiary Guarantor from
its obligations under its guaranty pursuant to this Section 13.09.


 




    -84-


     


    

 


(b) The
Administrative Agent will not be responsible for or have a duty to ascertain or inquire into any representation or warranty regarding
the existence, value or collectability of the Collateral, the existence, priority or perfection of the Administrative Agent’s
Lien thereon, or any certificate prepared by any Obligor in connection therewith, nor will the Administrative Agent be responsible
or liable to the Lenders for any failure to monitor or maintain any portion of the Collateral.


 


(c) Each
Lender hereby appoints the Administrative Agent as its collateral agent under each of the Security Documents and agrees that, in
so acting, the Administrative Agent will have all of the rights, protections, exculpations, indemnities and other benefits provided
to the Administrative Agent under this Agreement, and hereby authorizes and directs the Administrative Agent, on behalf of such
Lender and all Lenders, without the necessity of any notice to or further consent from any of the Lenders, from time to time to
(i) take any action with respect to any Collateral or any Security Document which may be necessary to perfect and maintain perfected
the Liens on the Collateral granted pursuant to any such Security Document or protect and preserve the Administrative Agent’s
ability to enforce the Liens or realize upon the Collateral, (ii) act as collateral agent for each Secured Party for purposes of
acquiring, holding, enforcing and perfecting all Liens created by the Loan Documents and all other purposes stated therein, (iii)
enter into intercreditor or subordination agreements, as the case may be, in connection with Indebtedness permitted pursuant to
Section 9.01(n), (iv) enter into non-disturbance or similar agreements in connection with licensing agreements and arrangements
permitted by this Agreement and the other Loan Documents and (v) otherwise to take or refrain from taking any and all action that
the Administrative Agent shall deem necessary or advisable in fulfilling its role as collateral agent under any of the Security
Documents.


 


Section 14. Miscellaneous.


 


Section
14.01. No Waiver. No failure on the part of the Administrative Agent or the Lenders to exercise and no delay in exercising,
and no course of dealing with respect to, any right, power or privilege under any Loan Document shall operate as a waiver thereof,
nor shall any single or partial exercise of any right, power or privilege under any Loan Document preclude any other or further
exercise thereof or the exercise of any other right, power or privilege. The remedies provided herein are cumulative and not exclusive
of any remedies provided by law.


 


Section
14.02. Notices. All notices, requests, instructions, directions and other communications provided for herein (including any

Etc.


 


(a) Closing
Expenses. The Borrower agrees to pay or reimburse the Administrative Agent and the Lenders for all of their reasonable and

 (b) the consent of all of the Lenders shall be required to:

Section 14.05. Successors and Assigns.


 


(a) General.
This Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors
and assigns permitted hereby; provided that the neither the Borrower nor any other Obligor may assign or transfer its rights
or obligations hereunder without the prior written consent of the Administrative Agent. No Lender may assign or otherwise transfer
any of its rights or obligations hereunder or under any of the other Loan Documents except (i) to an assignee in accordance with
the provisions of Section 14.05(b), or (ii) by way of participation in accordance with the provisions of Section 14.05(e)
(and any other attempted assignment or transfer by any party hereto shall be null and void). Nothing in this Agreement, expressed
or implied, shall be construed to confer upon any Person (other than the parties hereto, their respective successors and assigns
permitted hereby, Participants to the extent provided in Section 14.05(e) and, to the extent expressly contemplated hereby, the
Indemnified Parties) any legal or equitable right, remedy or claim under or by reason of this Agreement.


 


(b) Assignments
by Lender. Any of the Lenders may at any time assign to one or more Eligible Transferees (or, if an Event of Default has occurred
and is continuing, to any Person) all or a portion of its rights and obligations under this Agreement (including all or a portion
of the Commitment and the Term Loan at the time owing to it) and the other Loan Documents; provided that no such assignment
shall be made to the Borrower, any Affiliate of the Borrower or any employees or directors of any Obligor at any time. Subject
to the recording thereof by the Administrative Agent pursuant to Section 14.05(d), from and after the effective date specified
in each Assignment and Assumption, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest
assigned by such Assignment and Assumption, have the rights and obligations of such Lender under this Agreement and the other
Loan Documents, and correspondingly the assigning Lender shall, to the extent of the interest assigned by such Assignment and
Assumption, be released from its obligations under this Agreement (and, in the case of an Assignment and Assumption covering all
of the Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) and the other
Loan Documents but shall continue to be entitled to the benefits of Section 5 and Section 14.03. Any assignment or transfer by
a Lender of rights or obligations under this Agreement that does not comply with this Section 14.05(b) shall be treated for purposes
of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 14.05(e).


 






    -87-


     


    

 


(c) Amendments
to Loan Documents. Each of the Lenders and the Obligors agrees to enter into such amendments to the Loan Documents, and such
additional Security Documents and other instruments and agreements, in each case in form and substance reasonably acceptable to
the Lenders and the Obligors, as shall reasonably be necessary to implement and give effect to any assignment made under this Section
14.05.


 


(d) Register.
The Administrative Agent shall maintain a copy of each Assignment and Assumption delivered to it pursuant to clause (b) above
and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts (and
stated interest) of the Term Loan owing to, each Lender pursuant to the terms hereof from time to time (the “Register”).
The entries in the Register shall be conclusive absent manifest error, and the Borrower, the Administrative Agent and the Lenders
shall treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes
of this Agreement. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from
time to time upon reasonable prior notice. The Obligations under the Loan Documents (other than the Warrant Obligations) are intended
to be maintained in, and this Section shall be construed so that the Commitments and Term Loan are at all times maintained in,
“registered form” within the meaning of Section 163(f), 871(h)(2) and 881(c)(2) of the Code and any related regulations
(and any other relevant or successor provisions of the Code or such regulations).


 


(e) Participations.
Any of the Lenders may at any time, without the consent of, or notice to, the Borrower, sell participations to any Person
which would constitute an Eligible Transferee (other than a natural person or a holding company, investment vehicle or trust for,
or owned and operated for the primary benefit of, a natural person or Parent or any of Parent’s Affiliates or Subsidiaries)
(each, a “Participant”) in all or a portion of such Lender’s rights and/or obligations under this Agreement
(including all or a portion of the Commitment and/or the Term Loan owing to it); provided that (i) such Lender’s
obligations under this Agreement shall remain unchanged, (ii) such Lender shall remain solely responsible to the other parties
hereto for the performance of such obligations and (iii) the Borrower shall continue to deal solely and directly with such Lender
in connection therewith. Any agreement or instrument pursuant to which a Lender sells such a participation shall provide that
such Lender shall retain the sole right to enforce this Agreement and to approve any amendment, modification or waiver of any
provision of this Agreement; provided that such agreement or instrument may provide that such Lender will not, without
the consent of the Participant, agree to any amendment, modification or waiver that would (i) increase or extend the term of such
Lender’s Commitment, (ii) extend the date fixed for the payment of principal of or interest on the Term Loan or any portion
of any fee hereunder payable to the Participant, (iii) reduce the amount of any such payment of principal, or (iv) reduce the
rate at which interest is payable thereon to a level below the rate at which the Participant is entitled to receive such interest
(other than with respect to default interest). The Borrower agrees that each Participant shall be entitled to the benefits of
Section 5 (subject to the requirements and limitations therein, including the requirements of Section 5.03(f) (it being understood
that the documentation required under Section 5.03(f) shall be delivered to the participating Lender)) to the same extent as if
such Participant had acquired its interest by assignment pursuant to Section 14.05(b); provided that such Participant shall
not be entitled to receive any greater payment under Section 5 with respect to any participation, than its participating Lender
would have been entitled to receive. To the extent permitted by Law, each Participant also shall be entitled to the benefits of
Section 4.03(a) as though it were a Lender. Each Lender that sells a participation shall, acting solely for this purpose as a
non-fiduciary agent of the Borrower, maintain a register on which it enters the name and address of each Participant and the principal
amounts (and stated interest) of each Participant’s interest in the Term Loan or other obligations under the Loan Documents
(the “Participant Register”); provided that no Lender shall have any obligation to disclose all or any
portion of the Participant Register (including the identity of any Participant or any information relating to a Participant’s
interest in any commitments, loans, letters of credit or its other obligations under any Loan Document) to any Person except to
the extent that such disclosure is necessary to establish that such commitment, loan, letter of credit or other obligation is
in registered form under Section 5f.103-1(c) of the United States Treasury Regulations. The entries in the Participant Register
shall be conclusive absent manifest error, and the parties hereto shall treat each Person whose name is recorded in the Participant
Register as the owner of such participation for all purposes of this Agreement notwithstanding any notice to the contrary.

(f) Security
Interest. Notwithstanding anything to the contrary contained in this Section 14.05, a Lender may collaterally assign any of
its rights or obligations hereunder or under any of the other Loan Documents by way of pledge or collateral assignment of all or
a portion of such Lender’s rights under the Loan Documents to a Federal Reserve Bank provided that no such pledge or assignment
shall release such Lender from its obligations hereunder.


 


Section 14.06. Survival.
The obligations of the Borrower under Sections 5.01, 5.02, 5.03, 14.03 and the obligations of Parent and the Subsidiary Guarantors
under Section 12 (solely to the extent guaranteeing any of the obligations under the foregoing Sections) shall survive the repayment
of the Obligations and the termination of the Commitment and, in the case of the Lenders’ assignment of any interest in
the Commitment or the Term Loan hereunder, shall survive, in the case of any event or circumstance that occurred prior to the
effective date of such assignment, the making of such assignment, notwithstanding that the Lenders may cease to be “Lenders”
hereunder. In addition, each representation and warranty made herein or pursuant hereto shall survive the making of such representation
and warranty.

as delivery of a manually executed counterpart hereof.


 


Section
14.09. Governing Law. This Agreement and the rights and obligations of the parties hereunder shall be governed by, and construed
in accordance with, the law of the State of New York, without regard to principles of conflicts of laws that would result in the
application of the laws of any other jurisdiction; provided that Section 5-1401 of the New York General Obligations Law
shall apply.


 


Section 14.10. Jurisdiction, Service of Process
and Venue.


 


(a) Submission
to Jurisdiction. Each Obligor agrees that any suit, action or proceeding with respect to this Agreement or any other Loan Document
to which it is a party or any judgment entered by any court in respect thereof may be brought initially in the federal or state
courts in New York, New York or in the courts of its own corporate domicile and irrevocably submits to the exclusive jurisdiction
of each such court for the purpose of any such suit, action, proceeding or judgment. This Section 14.10(a) is for the benefit of
the Administrative Agent and the Lenders only and, as a result, neither the Administrative Agent nor any Lender shall be prevented
from taking proceedings in any other courts located in the United States with jurisdiction, or to the extent assets of an Obligor
are or may be located in a foreign jurisdiction, in such foreign jurisdiction. To the extent allowed by any Law, the Administrative
Agent and the Lenders may take concurrent proceedings in any number of jurisdictions located in the United States and any foreign
jurisdictions where the assets of any Obligor are or may be located.


 


(b) Alternative
Process. Nothing herein shall in any way be deemed to limit the ability of the Lenders to serve any process or summons in any
manner permitted by Law.


 


(c) Waiver
of Venue, Etc. Each Obligor irrevocably waives to the fullest extent permitted by law any objection that it may now or hereafter
have to the laying of the venue of any suit, action or proceeding arising out of or relating to this Agreement or any other Loan
Document and hereby further irrevocably waives to the fullest extent permitted by law any claim that any such suit, action or proceeding
brought in any such court has been brought in an inconvenient forum. A final judgment (in respect of which time for all appeals
has elapsed) in any such suit, action or proceeding shall be conclusive and may be enforced in any court to the jurisdiction of
which such Obligor is or may be subject, by suit upon judgment.


 


Section
14.11. Waiver of Jury Trial. Each Obligor,
the Administrative Agent
and each Lender hereby irrevocably waives, to the fullest
extent permitted by applicable law, any and all right to trial by jury in any suit,
action or proceeding arising out of or relating to this Agreement,
the other Loan Documents
or the transactions contemplated hereby or thereby.

Section
14.12. Waiver of Immunity. To the extent that any Obligor may be or become entitled to claim for itself or its property or
revenues any immunity on the ground of sovereignty or the like from suit, court jurisdiction, attachment prior to judgment, attachment
in aid of execution of a judgment or execution of a judgment, and to the extent that in any such jurisdiction there may be attributed
such an immunity (whether or not claimed), such Obligor hereby irrevocably agrees not to so claim and hereby irrevocably waives
such immunity with respect to its obligations under this Agreement and the other Loan Documents.


 


Section
14.13. Entire Agreement. This Agreement and the other Loan Documents constitute the entire agreement among the parties with
respect to the subject matter hereof and thereof and supersede any and all previous agreements and understandings, oral or written,
relating to the subject matter hereof, including any confidentiality (or similar) agreements. Each
Obligor acknowledges, represents and warrants that in
deciding to enter into this agreement and the other Loan
Documents or in taking or not taking any action hereunder or thereunder, it
has not relied, and will not rely, on any statement,
representation, warranty, covenant,
agreement or understanding, whether written or oral,
of or with the Lenders other than those expressly set forth
in this Agreement and the other Loan Documents.


 


Section
14.14. Severability. If any provision hereof is found by a court to be invalid or unenforceable, to the fullest extent permitted
by any applicable Law the parties agree that such invalidity or unenforceability shall not impair the validity or enforceability
of any other provision hereof.


 


Section
14.15. No Fiduciary Relationship. The Borrower acknowledges that the Administrative Agent and the Lenders have no fiduciary
relationship with, or fiduciary duty to, the Borrower arising out of or in connection with this Agreement or the other Loan Documents,
and the relationship between the Lenders and the Borrower is solely that of creditor and debtor. This Agreement and the other Loan
Documents do not create a joint venture among the parties.


 


Section
14.16. Confidentiality. Each Lender agrees to keep confidential all non-public information provided to it by any Obligor pursuant
to this Agreement; provided that nothing herein shall prevent any Lender from disclosing any such information (i) to any
other Lender or, subject to a written agreement to comply with the provisions of this Section 14.16, any Affiliate of a another
Lender or any prospective assignee or participant of the Term Loan permitted by and pursuant to Section 14.05(b) or (d) that,
in each case, is also subject to confidentiality provisions at least as stringent as the provisions of this Section 14.16, (ii)
subject to an agreement to comply with the provisions of this Section, to any actual or prospective direct or indirect counterparty
to any Hedging Agreement (or any professional advisor to such counterparty), (iii) to its Affiliates employees, officers, directors,
agents, attorneys, accountants, trustees and other professional advisors (collectively, its “Related Parties”);
provided that the applicable Lender shall remain liable hereunder for any breach of this Section 14.16 by any of its Related
Parties, (iv) upon the request or demand of any Governmental Authority or any Regulatory Authority having jurisdiction over such
Person or its Related Parties (including any self-regulatory authority, such as the National Association of Insurance Commissioners),
(v) in response to any order of any court or other Governmental Authority or as may otherwise be required pursuant to any applicable
Law, (vi) if required to do so in connection with any litigation or similar proceeding, (vii) that has been publicly disclosed
(other than as a result of a disclosure in violation of this Section 14.16), (viii) on a confidential basis to the National Association

with the exercise of any remedy permitted hereunder or under any other Loan Document, (x) on a confidential basis to (A) any rating
agency in connection with rating Parent or its Subsidiaries or the Term Loan or (B) the CUSIP Service Bureau or any similar agency
in connection with the issuance and monitoring of CUSIP numbers of other market identifiers with respect to the Term Loan or (xi)
to any other party that is, and is permitted pursuant to the terms hereof to be, a party hereto; provided further that,
unless specifically prohibited by applicable law or court order, each Lender shall notify the Borrower of any request by any Governmental
Authority or Regulatory Authority or representative thereof (other than any such request in connection with any examination of
the financial condition or other routine examination of such Lender by such Governmental Authority or Regulatory Authority) for
disclosure of any such non-public information prior to disclosure of such information to enable the Borrower to seek a protection
order or otherwise prevent or restrict such disclosure.

Section
14.17. Right of Setoff. If an Event of Default shall have occurred and be continuing, each Lender and each of its Affiliates
is hereby authorized at any time and from time to time, to the fullest extent permitted by applicable Law, to set off and apply
any and all deposits (general or special, time or demand, provisional or final, in whatever currency) at any time held and other
obligations (in whatever currency) at any time owing by such Lender or any such Affiliate to or for the credit or the account of
the Borrower or any other Obligor against any and all of the Obligations now or hereafter existing under this Agreement or any
other Loan Document to such Lender or its Affiliates, irrespective of whether or not such Lender or Affiliate shall have made any
demand under this Agreement or any other Loan Document and although such Obligations of the Borrower or such Obligor may be contingent
or unmatured or are owed to an Affiliate of such Lender. The rights of each Lender and its Affiliates under this Section are in
addition to other rights and remedies (including other rights of setoff) that such Lender and Affiliates may have. Each Lender
agrees to notify the Borrower promptly after any such setoff and application; provided that the failure to give such notice
shall not affect the validity of such setoff and application.


 


Section
14.18. Judgment Currency. (a) If, for the purposes of obtaining judgment in any court, it is necessary to convert a sum due
hereunder in Dollars into another currency, the parties hereto agree, to the fullest extent permitted by Law, that the rate of
exchange used shall be that at which, in accordance with normal banking procedures, the Administrative Agent could purchase Dollars
with such other currency at the buying spot rate of exchange in the New York foreign exchange market on the Business Day immediately
preceding that on which any such judgment, or any relevant part thereof, is given.


 


(b) The
obligations of the Obligors in respect of any sum due to the Administrative Agent hereunder and under the other Loan Documents
shall, notwithstanding any judgment in a currency other than Dollars, be discharged only to the extent that on the Business Day
following receipt by the Administrative Agent of any sum adjudged to be so due in such other currency the Administrative Agent
may, in accordance with normal banking procedures, purchase Dollars with such other currency. If the amount of Dollars so purchased
is less than the sum originally due to the Administrative Agent in Dollars, the Borrower agrees, to the fullest extent that it
may effectively do so, as a separate obligation and notwithstanding any such judgment, to indemnify the Administrative Agent against
such loss. If the amount of Dollars so purchased exceeds the sum originally due to the Administrative Agent in Dollars, the Administrative
Agent shall remit such excess to the Borrower.

Section
14.19. USA PATRIOT Act. The Administrative Agent and the Lenders hereby notify the Obligors that pursuant to the requirements
of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), they are
required to obtain, verify and record information that identifies the Obligors, which information includes the name and address
of each Obligor and other information that will allow such Person to identify such Obligor in accordance with the Act.

disposed of or to be sold or otherwise disposed of as part of or in connection with an Asset Sale permitted pursuant to

Agent and (ii) to release any Subsidiary Guarantor from its obligations as a guarantor hereunder if such Person ceases to be

or similar agreements in connection with licensing agreements permitted by this Agreement or any other Loan Document, in each case
in form and substance reasonably satisfactory to the Administrative Agent and the counterparty or counterparties to the licensing
agreements.


 


Section
14.21. Acknowledgement and Consent to Bail-In of EEA Financial Institutions. Notwithstanding anything to the contrary in any
Loan Document or in any other agreement, arrangement or understanding among any such parties, each party hereto acknowledges that
any liability of any EEA Financial Institution arising under any Loan Document, to the extent such liability is unsecured, may
be subject to the write-down and conversion powers of an EEA Resolution Authority and agrees and consents to, and acknowledges
and agrees to be bound by:


 


(a) the
application of any Write-Down and Conversion Powers by an EEA Resolution Authority to any such liabilities arising hereunder which

effects of any Bail-In Action on any such liability, including, if applicable:

conversion of all, or a portion of, such liability into shares or other instruments of ownership in such EEA Financial Institution,
its parent undertaking, or a bridge institution that may be issued to it or otherwise conferred on it, and that such shares or
other instruments of ownership will be accepted by it in lieu of any rights with respect to any such liability under this Agreement
or any other Loan Document; or


 


(iii) the
variation of the terms of such liability in connection with the exercise of the write-down and conversion powers of any EEA Resolution
