Forbearance
Agreement and


First
Amendment to Credit Agreement
and Guaranty


 


This
Forbearance Agreement and First Amendment to Credit Agreement and Guaranty (herein, this “Agreement”) is entered
into as of August 27, 2019, 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 (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) of the Existing Credit Agreement, resulting in Events of Default
under Sections 11.01(d) and (e), respectively, of the Existing Credit Agreement (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 December 31,
2019 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. First
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 First Amendment. Schedule 1
to the Existing Credit Agreement is hereby amended and replaced in its entirety with Schedule 1 attached hereto.

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.

purposes of this Agreement and the other
Loan Documents.


 


Section

Term Loan becomes due and payable in full prior to the First Amendment Maturity Date in accordance with the terms hereof, in the

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 and the 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 or
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

owing 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

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

(c) Interest
Payment Dates. Accrued interest on the Closing Date Term Loan shall be payable in cash and in arrears on each Payment Date

Rate. Notwithstanding any other provision of this Agreement, in no event will any interest or rates referred to herein exceed
the maximum interest rate permitted by applicable law. If such maximum interest rate would be exceeded by the terms hereof, the
rates of interest payable hereunder will be reduced to the extent necessary so that such rates (together with any fees or other
amounts which are construed by a court of competent jurisdiction to be interest or in the nature of interest) equal the maximum
interest rate permitted by applicable law, and any overpayment of interest received by the Lenders before such rates are so construed
will be applied, forthwith after determination of such overpayment, to pay all then outstanding interest, and thereafter to pay
outstanding principal.


 


Section 3.03. Prepayments; Prepayment

Cash Proceeds received by the Borrower or any other Obligor as a result of such Casualty Event up to the principal amount
outstanding of the Term Loan, and (y) any accrued but unpaid interest on such principal amount of the Term Loan being
prepaid; provided that so long as no Default or Event of Default has occurred and is continuing at the time the
Borrower or any (b) Obligor shall have received such Net Cash Proceeds, if, within five (5) Business Days following the
occurrence of any such Casualty Event, a Responsible Officer of the Borrower may deliver to the Administrative Agent a notice
(each, a “Casualty Event Reinvestment Notice”) to the effect that the Borrower or applicable Obligor
intends to apply the Net Cash Proceeds from such Casualty Event to acquire, replace or rebuild the property subject to such
Casualty Event or to the cost of purchase or construction of other assets useful in the business of Parent or its
Subsidiaries, then such Net Cash Proceeds of such Casualty Event may be applied for such purpose in lieu of such mandatory
prepayment, provided further that, in the event that Net Cash Proceeds have not been so applied within one hundred
eighty (180) days following the occurrence of such Casualty Event, the Borrower shall make a mandatory prepayment of the Term

that such Persons may have.


 


(b) Exercise
of Rights Not Required. Nothing contained in Section 4.03(a) shall require the Administrative Agent, any Lender or any of their

Section 5. Yield Protection, Etc.


 


Section 5.01. Additional Costs.


 


(a) Change
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
interpretation or administration thereof by any court or other Governmental Authority charged with the interpretation or administration
thereof, or compliance by any Lender (or its lending office) with any request or directive (whether or not having the force of
law) of any such Governmental Authority, shall impose, modify or deem applicable any reserve (including any such requirement imposed
by the Board of Governors of the Federal Reserve System), special deposit, contribution, insurance assessment or similar requirement,
in each case that becomes effective after the date hereof, against assets of, deposits with or for the account of, or credit extended
by, a Lender (or its lending office) or shall impose on a Lender (or its lending office) any other condition affecting the Term
Loan or the Commitment, and the result of any of the foregoing is to increase the cost to such Lender of making or maintaining
the Term Loan, or to reduce the amount of any sum received or receivable by such Lender under this Agreement or any other Loan
Document, or subject any Lender to any Taxes on its Term Loan, Commitment or other obligations, or its deposits, reserves, other
liabilities or capital (if any) attributable thereto by an amount reasonably deemed by such Lender in good faith to be material
(other than (i) Indemnified Taxes, (ii) Taxes described in clauses (ii) through (iv) of the definition of “Excluded Taxes”
and (iii) Connection Income Taxes), then the Borrower shall pay to such Lender on demand such additional amount or amounts as
will compensate such Lender for such increased cost or reduction.


 






    -32-


     


    

 


(b) Change
in Capital Requirements. If a Lender shall have determined that, on or after the date hereof, the adoption of any applicable
Law regarding capital adequacy, or any change therein, or any change in the interpretation or administration thereof by any Governmental
Authority charged with the interpretation or administration thereof, or any request or directive regarding capital adequacy (whether
or not having the force of law) of any such Governmental Authority, in each case that becomes effective after the date hereof,
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.


 


(c) Notification
by Lender. Each Lender will promptly notify the Borrower of any event of which it has knowledge, occurring after the date hereof,
which will entitle such Lender to compensation pursuant to this Section 5.01. Before giving any such notice pursuant to this Section
5.01(c) such Lender shall designate a different lending office if such designation (x) will, in the reasonable judgment 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 5.01, setting
forth in reasonable detail the additional amount or amounts to be paid to it hereunder, shall be conclusive and binding on the
Borrower in the absence of manifest error.


 


(d) Notwithstanding
anything herein to the contrary, (x) the Dodd-Frank Wall Street Reform and Consumer Protection Act and all requests, rules, guidelines
or directives thereunder or issued in connection therewith and (y) all requests, rules, guidelines or directives promulgated by
the Bank for International Settlements, the Basel Committee on Banking Supervision (or any successor or similar authority) or the
United States or foreign regulatory authorities, in each case pursuant to Basel III, shall in each case be deemed to constitute
a change in Law for all purposes of this Section 5.01, regardless of the date enacted, adopted or issued.


 


Section 5.02.
Illegality. Notwithstanding any other provision of this Agreement, in the event that on or after the date hereof the
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 equal to the aggregate principal amount of the Term Loan outstanding on the date
of such prepayment plus any accrued but unpaid interest thereon.


 






    -33-


     


    

 


Section 5.03. Taxes. For purposes
of this Section 5.03, the term “applicable Law” includes FATCA.


 


(a) Payments
Free of Taxes. Any and all payments by or on account of any Obligation shall be made without deduction or withholding for any
Taxes, except as required by any applicable Law. If any applicable Law (as determined in the good faith discretion of an applicable
Withholding Agent) requires the deduction or withholding of any Tax from any such payment by a Withholding Agent, then the applicable
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
to this Section 5.03, the Borrower shall deliver to the Administrative Agent the original or a certified copy of a receipt issued
by such Governmental Authority evidencing such payment, a copy of the return reporting such payment or other evidence of such payment
reasonably satisfactory to the Administrative Agent.


 


(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).


 






    -34-


     


    

 


(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

(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

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;

substantially in the form of Exhibit D-2 or D-3, IRS Form W-9 (or successor form), and/or other certification documents from each
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.


 


(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


 






    -36-


     


    

 


(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.


 


(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.


 




    -37-


     


    

 


(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

Effect, and (iv) has full power, authority and legal right to enter into and perform its obligations under each of the Loan
Documents to which it is a party and, in the case of the Borrower, to borrow the Term Loan hereunder.

insolvency, reorganization, moratorium or similar laws of general applicability affecting the enforcement of creditors’ rights
and (ii) the application of general principles of equity (regardless of whether such enforceability is considered in a proceeding
in equity or at law).

Material Agreement or (y) any Contract creating or evidencing any Material Indebtedness or

(which material terms shall include, but not be limited to, pricing and duration of the agreement), and all such Material Agreements
are in full force and effect, and Obligors have no knowledge of any facts which could form a reasonable basis for any claims of
breach or default under such Material Agreements.


 


(ix) Other
than those permitted by Section 9.09, or as set forth on Schedule 7.05(b), (a) there are no outstanding options, licenses, agreements,

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

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.

restrictive covenant to or with a former employer where the basis of such violation relates to such employee’s employment
with Obligors.

of, or failing to enforce and defend, any of its Intellectual Property if, in the reasonable good faith judgment of such Obligor
or such Subsidiary, such Intellectual Property is no longer necessary and material to the conduct of its business.

Section 11.02. Remedies. Upon the
occurrence of any Event of Default (other than an Event of Default described in Section 11.01(i)), then, and in every such event,
and at any time thereafter during the continuance of such event, the Administrative Agent may, by notice to the Borrower, declare
the Term Loan then outstanding to be due and payable in whole (or in part, in which case any principal 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 11.03. Additional
Remedies. Upon the occurrence and during the continuance of any Event of Default, (a) if any Obligor or any of its
Subsidiaries shall be in default under a Material Agreement, the Lenders shall have the right (but not the obligation) to
cause the default or defaults under such Material Agreement to be remedied (including without limitation by paying any unpaid
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”.


 


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.


 






    -73-


     


    

 


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 and (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, in the case of each of clause (x) and (y) 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
and the 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 or 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 otherwise) of the principal of

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:


 




    -74-

be done or omitted;


 


(c) the
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
or any other guarantee of any of the Guaranteed Obligations or any security therefor shall be released or exchanged in whole or
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.


 


Section 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 any bankruptcy, insolvency
or similar Law.


 


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.


 






    -75-


     


    

 


Section 12.06. Instrument for the Payment
of Money. Parent and each Subsidiary Guarantor hereby acknowledges that the guarantee in this Section 12 constitutes an instrument
for the payment of money, and consents and agrees that the Administrative Agent and the Lenders, at their sole option, in the event
of a dispute by Parent or such Subsidiary Guarantor in the payment of any moneys due 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.


 


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.


 


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.


 




    -77-


     


    

 


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.

enforceability, effectiveness or genuineness of this Agreement, any other Loan Document or any other agreement, instrument or document

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.


 


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.


 






    -80-


     


    

 


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.


 


(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 14.01. 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

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).


 


(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).


 






    -84-


     


    

 


(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.


 






    -85-


     


    

 


(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.

of this Agreement by facsimile transmission or electronic transmission (in PDF format) shall be effective 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

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

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

of sovereignty or the like from suit, court jurisdiction, attachment prior to judgment, attachment in aid of execution of a judgment

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.

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

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.

Obligations (other than Warrant Obligations and contingent obligations as to which no claims have been asserted) have been
satisfied in full in cash, (B) that is sold or otherwise disposed of or to be sold or otherwise disposed of as part of or in
connection with an Asset Sale permitted pursuant to Section 9.09 or (C) subject to Sections 14.01 and 14.04, if approved,
authorized or ratified in writing by the Administrative Agent and (ii) to release any Subsidiary Guarantor from its

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
