 4. Non-Disclosure and Confidentiality Obligations. 
 a. Provided that the Company has not breached its obligations to make the payments and benefits to Tarnoff described in Section 1 above, Tarnoff shall not, without the prior written consent of the Company in its
sole discretion, for any reason or for any purpose, either directly or indirectly, divulge to any third-party or use for his own direct or indirect benefit, any Company Information (as defined below) revealed to or obtained by Tarnoff at any time
during the course of his employment with the Company (whether developed by Tarnoff or any other person or entity on behalf of the Company). “Company Information” generally means all of the Company’s confidential, proprietary, business
and technical information, trade secrets or other information or materials that have not been made available to the general public by the Company, and shall include, but shall not be limited to: the Company’s relationship, conversations,
correspondence and course of dealing with state, federal and local governmental and regulatory authorities, including but not limited to the United States Food and Drug Administration; all information relating to the Company’s existing or
proposed discovery, pre-clinical, clinical research and development and business development efforts; business or products; intangible personal property, the Company’s relationship with, the terms of contracts and agreements with, the needs and

using for his own benefit or for any other purpose any Company Information that is readily available to the general public so long as such information did not become available to the general public as a direct or indirect result of a breach of this
Section 4 by Tarnoff. Failure by the Company to mark any of the Company Information as confidential or proprietary shall not affect its status as Company Information under the terms of this Agreement. Tarnoff shall provide to the Company
written notice of any written or oral request, including but not limited to, telephone inquiries, written requests or subpoenas, by any person, entity, governmental agency or regulatory authority seeking Company Information within three
(3) business days of receiving such request. It is understood that Tarnoff will comply with all subpoenas which are served on him unless directed otherwise by a court of competent jurisdiction. Notwithstanding the foregoing, this
Section 4.a. is not intended to prevent Tarnoff from providing consulting services to any third party, or from engaging or otherwise entering into a business relationship with any of the Company’s collaborators, clinical investigators,
contract research organizations, suppliers or contactors, provided that Tarnoff does not use or disclose any Company Information in connection with the performance of such Services. 
  

 4 

 b. Tarnoff shall refrain from initiating any contact with any person, entity or government agency with
respect to any investigation or inquiry into any aspect of the Company’s business operations or employment practices, except as provided by or required by law and subject to the second and third to last sentences of Section 4.a. above.

 c. Neither party shall disclose or publicize the terms of this Agreement, directly or indirectly, to any person or entity; provided that
Tarnoff and the Company may disclose that the parties have resolved any differences between them pursuant to the terms of a confidential settlement agreement; and provided further that the Company and Tarnoff may disclose the terms, and/or fact of
this Agreement to their respective accountants, attorneys, actual and potential investors and creditors, provided that each of the foregoing agrees to keep the terms of this Agreement confidential (each, a “Permitted Recipient”), and to
others as required by law, rule or regulation. Tarnoff acknowledges that the Company will disclose this Agreement or certain information relating to this Agreement in its filings with the Securities and Exchange Commission. Any breach of this
Section 4.c. by a Permitted Recipient shall be deemed a breach of this Agreement by the party hereto that disclosed the terms of this Agreement to such Permitted Recipient.

possession or subject to him direct or indirect control. “Company Property” shall include, but shall not be limited to: all notes, memoranda, reports (including all drafts thereof), correspondence, telephone contact reports and other

 7. No Admissions. Neither the execution of this Agreement by the Company or Tarnoff, nor the terms

	4.	Confidential Information. 

 (a) “Confidential
Information” means any information, materials or methods in whatever form or embodiment that has not been made available by ViroPharma to the general public and any information, materials or methods materially developed therefrom, except that
Confidential Information shall not include any information, material or method that: 
  

	 	(i)	at the time of disclosure is in, or after disclosure becomes part of the public domain, through no improper act on the part of Consultant or any of its employees;

  

 9 

	 	(ii)	was in Consultant’s possession at the time of disclosure, as shown by written evidence, and was not acquired, directly or indirectly, from ViroPharma; 

 

	 	(iii)	Consultant receives from a third party, provided that such Confidential Information was not obtained by such third party, directly or indirectly, from ViroPharma; or

  

	 	(iv)	is independently developed by Consultant without reference to Confidential Information. 

 Specific information disclosed as part of the Confidential Information shall not be deemed to be in the public domain or in the prior possession of Consultant merely because it is embraced by more general information
in the public domain or in the prior possession of the Consultant. Failure to mark any of the Confidential Information as confidential or proprietary shall not affect its status as Confidential Information under the terms of this Agreement.

 (b) Consultant shall keep all Confidential Information confidential, and Consultant shall not disclose, disseminate, publish, reproduce or
use Confidential Information except to perform the Services. Consultant shall, at a minimum, take those precautions with respect to the Confidential Information that Consultant uses to protect Consultant’s own confidential information. If
Consultant is required by judicial or administrative process to disclose Confidential Information, Consultant shall promptly notify ViroPharma to allow ViroPharma a reasonable time to oppose such process. Any breach of this Section 4 by an

 5. Property. Consultant may remove materials containing Confidential Information from ViroPharma’s premises only for as long as necessary to perform the
Services and Consultant shall return all such materials and all copies thereof promptly, but in any event no later than the date of termination or expiration of this Agreement. 
 6. Intellectual Property. ViroPharma shall be the sole and exclusive owner of any and all writings, documents, works made for hire, inventions, discoveries, know-how, processes, chemical entities, compounds,
plans, memoranda, tests, research, designs, specifications, models and data that Consultant makes, conceives, discovers or develops, either solely or jointly with 

  

 10 

 
any other person in performance of the Services (collectively, “Work Product”). Consultant shall promptly disclose to ViroPharma all information
relating to Work Product. Consultant acknowledges that all of the Work Product that is copyrightable shall be considered a work made for hire under United States Copyright Law. To the extent that any copyrightable Work Product may not be considered
a work made for hire under Copyright Law or to the extent that, notwithstanding the foregoing provisions, Consultant may retain an interest in any Work Product that is not copyrightable, Consultant hereby irrevocably assigns and transfers to
ViroPharma, and to the extent that an executory assignment is not enforceable, Consultant hereby agrees to assign and transfer to ViroPharma, in writing, from time to time, upon request, any and all right, title, or interest that Consultant has or
may obtain in any Work Product without the necessity of further consideration. ViroPharma shall be entitled to obtain and hold in its own name all copyrights, patents, trade secrets and trademarks with respect thereto. At ViroPharma’s request
and expense, Consultant shall assist ViroPharma in acquiring and maintaining its right in and title to, any Work Product. Such assistance may include, but will not be limited to, signing applications and other documents, cooperating in legal
proceedings, and taking any other steps considered necessary or desirable by ViroPharma. 
 7. Restrictive Covenants. During the term of this
Agreement and for two (2) years thereafter, Consultant shall not: 
 (a) interfere with any formal or informal business or other
relationship between ViroPharma and any third party; 
 (b) contact any of the ViroPharma’s then current personnel, whether employees or
independent contractors to offer such personnel employment, except that this prohibition shall not prevent any of such personnel (whether employees or independent contractors) from initiating contact with Consultant for the purpose of obtaining
employment. 
 8. Representations. Consultant represents that Consultant is not subject to any other agreement that Consultant will violate by signing
this Agreement. 
 9. Debarment. Consultant represents that Consultant has not been debarred under the provisions of the Generic Drug Enforcement Act
of 1992, including without limitation, 21 U.S.C. Section 335a. If, at any time during the term of this Agreement, Consultant (a) becomes debarred, or (b) receives notice of action or threat of action with respect to its debarment,
Consultant shall notify ViroPharma immediately. If Consultant becomes debarred, this Agreement shall terminate automatically without any further action or notice by ViroPharma. If Consultant receives notice as set forth in clause (b) above,
ViroPharma shall have the right to terminate this Agreement immediately. 
  

 11 

 10. Miscellaneous. 
 (a) Consultant is an independent contractor. Nothing contained in this Agreement shall create or imply the creation of a partnership or employment relationship between ViroPharma and Consultant. Neither party shall
have any authority to bind the other. ViroPharma shall not deduct or withhold from any monies payable to Consultant hereunder any amount for any tax or employee benefit. 
 (b) This Agreement shall be construed and enforced in accordance with the laws of the Commonwealth of Pennsylvania, without regard to the conflict of law principles of Pennsylvania or any other jurisdiction. Any legal
proceeding relating to this Agreement shall, at ViroPharma’s option, be instituted exclusively in the United States District Court for the Eastern District of Pennsylvania or in any court of general jurisdiction in Chester County, Pennsylvania,
and Consultant hereby consents to the personal and exclusive jurisdiction of such court and hereby waives any objection that Consultant may have to the laying of venue of any such proceeding and any claim or defense of inconvenient forum.

 (c) If any provision of this Agreement is determined to be void, invalid, unenforceable or illegal for any reason, the validity and
enforceability of all of the remaining provisions hereof shall not be affected thereby. 
 (d) The parties acknowledge that it is impossible
to measure fully, in money, the injury that will be caused in the event of a breach or threatened breach of Sections 4, 5 or 6 of this Agreement, and Consultant waives and shall not assert the claim or defense that ViroPharma has an adequate remedy
at law. ViroPharma’s receipt of injunctive relief to enforce the provisions of this Agreement shall not prevent ViroPharma from seeking or obtaining any other remedy it may have at law or in equity, and the prevailing party in any such
litigation shall be entitled to recover all reasonable expenses of litigation, including reasonable attorney fees. 
 (e) This Agreement
contains the entire agreement and understanding of the parties relating to the subject matter hereof and merges and supersedes all prior discussions, agreements and understandings of every nature between them relating to the subject matter hereof.
This Agreement may not be amended except by written agreement signed by both of the parties hereto. The waiver of the breach of any term or provision of this Agreement shall not be a waiver of any other or subsequent breach of this Agreement. This
Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and when taken together shall constitute the same Agreement. The obligations of Consultant as set forth herein, other than
Consultant’s obligations to perform the Services, shall survive the termination of Consultant’s engagement. ViroPharma may assign this Agreement to, and this Agreement shall bind and inure to the benefit of, any assignee of ViroPharma.
This Agreement shall not be assignable by Consultant without the written consent of ViroPharma.

Agreement”) to induce an LC Issuer to issue or increase the amount of, or extend the expiry date of, one or more Letters of Credit and (ii) a Lender, identified by Agent, as an LC Issuer, of one or more Lender Letters of Credit, so
long as, in each case: 
 (i) Agent shall have received a Notice of LC Credit Event at least five (5) Business Days before the relevant
date of issuance, increase or extension; and

 Credit and Security Agreement Page 17 

 (ii) after giving effect to such issuance, increase or extension, (A) the aggregate Letter of Credit
Liabilities under all Letters of Credit do not exceed $25,000, and (B) the Revolving Loan Outstandings do not exceed the Revolving Loan Limit. 
 Nothing in this Agreement shall be construed to obligate any Lender to issue, increase the amount of or extend the expiry date of any letter of credit, which act or acts, if any, shall be subject to agreements to be entered into from time
to time between Borrowers and such Lender. Each Lender that is an LC Issuer hereby agrees to give Agent prompt written notice of each issuance of a Lender Letter of Credit by such Lender and each payment made by such Lender in respect of Lender
Letters of Credit issued by such Lender. 
 (b) Letter of Credit Fee. Borrowers shall pay to Agent, for the benefit of the Revolving
Lenders in accordance with their respective Pro Rata Shares, a letter of credit fee with respect to the Letter of Credit Liabilities for each Letter of Credit, computed for each day from the date of issuance of such Letter of Credit to the date that
is the last day a drawing is available under such Letter of Credit, at a rate per annum equal to the Base Rate Margin then applicable to Revolving Loans. Such fee shall be payable in arrears on the last day of each calendar month prior to the
Termination Date and on such date. In addition, Borrowers agree to pay promptly to the LC Issuer any fronting or other fees that it may charge in connection with any Letter of Credit. 
 (c) Reimbursement Obligations of Borrowers. If either (i) Agent shall make a payment to an LC Issuer pursuant to a Support Agreement, or
(ii) any Lender shall honor any draw request under, and make payment in respect of, a Lender Letter of Credit, (A) the applicable Borrower shall reimburse Agent or such Lender, as applicable, for the amount of such payment by the end of
the day on which Agent or such Lender shall make such payment and (B) Borrowers shall be deemed to have immediately requested that Revolving Lenders make a Revolving Loan, in a principal amount equal to the amount of such payment (but solely to
the extent such Borrower shall have failed to directly reimburse Agent or, with respect to Lender Letters of Credit, the applicable LC Issuer, for the amount of such payment). Agent shall promptly notify Revolving Lenders of any such deemed request
and each Revolving Lender (other than any such Revolving Lender that was a Non-Funding Lender at the time the applicable Supported Letter of Credit or Lender Letter of Credit was issued) hereby agrees to make available to Agent not later than noon
(Chicago time) on the Business Day following such notification from Agent such Revolving Lender’s Pro Rata Share of such Revolving Loan. Each Revolving Lender (other than any applicable Non-Funding Lender specified above) hereby absolutely and
unconditionally agrees to fund such Revolving Lender’s Pro Rata Share of the Loan described in the immediately preceding sentence, unaffected by any circumstance whatsoever, including, without limitation, (x) the occurrence and continuance
of a Default or Event of Default, (y) the fact that, whether before or after giving effect to the making of any such Revolving Loan, the Revolving Loan Outstandings exceed or will exceed the Revolving Loan Limit, and/or (z) the
non-satisfaction of any conditions set forth in Section 7.2. Agent hereby agrees to apply the gross proceeds of each Revolving Loan deemed made pursuant to this Section 2.4(c) in satisfaction of Borrowers’ reimbursement obligations
arising pursuant to this Section 2.4(c). Borrowers shall pay interest, on demand, on all amounts so paid by Agent pursuant to any Support Agreement or to any applicable Lender in honoring a draw request under any Lender Letter of Credit for
each day from the date of such payment until Borrowers reimburse Agent or the applicable Lender therefore (whether pursuant to clause (A) or (B) of the first sentence of this subsection (c)) at a rate per annum equal to the sum of two
percent (2%) plus the interest rate applicable to Revolving Loans for such day. 
 (d) Reimbursement and Other Payments by
Borrowers. The obligations of each Borrower to reimburse Agent and/or the applicable LC Issuer pursuant to Section 2.4(c) shall be absolute, unconditional and irrevocable, and shall be performed strictly in accordance with the terms of this
Agreement, under all circumstances whatsoever, including the following: 
 (i) any lack of validity or enforceability of, or any amendment or
waiver of or any consent to departure from, any Letter of Credit or any related document;

 Credit and Security Agreement Page 18 

 (ii) the existence of any claim, set-off, defense or other right which any Borrower may have at any time
against the beneficiary of any Letter of Credit, the LC Issuer (including any claim for improper payment), Agent, any Lender or any other Person, whether in connection with any Financing Document or any unrelated transaction, provided,
however, that nothing herein shall prevent the assertion of any such claim by separate suit or compulsory counterclaim; 
 (iii) any
statement or any other document presented under any Letter of Credit proving to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect whatsoever; 
 (iv) any affiliation between the LC Issuer and Agent; or 
 (v) to the extent permitted under applicable law, any other circumstance or happening whatsoever, whether or not similar to any of the foregoing. 
 (e) Deposit Obligations of Borrowers. In the event any Letters of Credit are outstanding at the time that Borrowers prepay or are required to
repay the Obligations or the Revolving Loan Commitment is terminated, Borrowers shall (i) deposit with Agent for the benefit of all Revolving Lenders cash in an amount equal to one hundred and ten percent (110%) of the aggregate
outstanding Letter of Credit Liabilities to be available to Agent, for its benefit and the benefit of issuers of Letters of Credit, to reimburse payments of drafts drawn under such Letters of Credit and pay any fees and expenses related thereto, and
(ii) prepay the fee payable under Section 2.4(b) with respect to such Letters of Credit for the full remaining terms of such Letters of Credit assuming that the full amount of such Letters of Credit as of the date of such repayment or
termination remain outstanding until the end of such remaining terms. Upon termination of any such Letter of Credit and provided no Event of Default has occurred and is continuing, the unearned portion of such prepaid fee attributable to such Letter
of Credit shall be refunded to Borrowers, together with the deposit described in the preceding clause (i) to the extent not previously applied by Agent in the manner described herein. 
 Section 2.5 General Provisions Regarding Payment; Loan Account. 
 (a) All payments to be made by each Borrower under any Financing Document, including payments of principal and interest made hereunder and pursuant to any other Financing Document, and all fees, expenses, indemnities
and reimbursements, shall be made without set-off, recoupment or counterclaim, in lawful money of the United States and in immediately available funds. If any payment hereunder becomes due and payable on a day other than a Business Day, such payment
shall be extended to the next succeeding Business Day and, with respect to payments of principal, interest thereon shall be payable at the then applicable rate during such extension (it being understood and agreed that, solely for purposes of
calculating financial covenants and computations contained herein and determining compliance therewith, if payment is made, in full, on any such extended due date, such payment shall be deemed to have been paid on the original due date without
giving effect to any extension thereto). Any payments received in the Payment Account before noon (Chicago time) on any date shall be deemed received by Agent on such date, and any payments received in the Payment Account after noon (Chicago time)
on any date shall be deemed received by Agent on the next succeeding Business Day. 
 (b) Agent shall maintain a loan account (the “Loan
Account”) on its books to record Loans and other extensions of credit made by the Lenders hereunder or under any other Financing Document, and all payments thereon made by each Borrower. All entries in the Loan Account shall be made in
accordance with Agent’s customary accounting practices as in effect from time to time. The balance in the Loan Account, as recorded in Agent’s books and records at any time shall be conclusive and binding evidence of the amounts due and
owing to Agent by each Borrower absent clear and convincing evidence to the contrary; provided, however, that any failure to so record or any error in so recording shall not limit or otherwise affect any Borrower’s duty to pay all
amounts owing hereunder or under any other Financing Document. Agent shall endeavor to provide Borrowers with a monthly statement regarding the Loan Account (but neither Agent nor any Lender shall have any liability if Agent shall fail to provide
any such statement). Unless any Borrower notifies Agent of any objection to any such statement (specifically describing the basis for such objection) within thirty (30) days after the date of receipt thereof, it shall be deemed final, binding
and conclusive upon Borrowers in all respects as to all matters reflected therein.

 Section 2.6 Maximum Interest. In no event shall the interest charged with respect to the
Notes (if any) or any other obligations of any Borrower under any Financing Document exceed the maximum amount permitted under the laws of the State of Illinois or of any other applicable jurisdiction. Notwithstanding anything to the contrary herein
or elsewhere, if at any time the rate of interest payable hereunder or under any Note or other Financing Document (the “Stated Rate”) would exceed the highest rate of interest permitted under any applicable law to be charged (the
“Maximum Lawful Rate”), then for so long as the Maximum Lawful Rate would be so exceeded, the rate of interest payable shall be equal to the Maximum Lawful Rate; provided, however, that if at any time thereafter the Stated
Rate is less than the Maximum Lawful Rate, each Borrower shall, to the extent permitted by law, continue to pay interest at the Maximum Lawful Rate until such time as the total interest received is equal to the total interest which would have been
received had the Stated Rate been (but for the operation of this provision) the interest rate payable. Thereafter, the interest rate payable shall be the Stated Rate unless and until the Stated Rate again would exceed the Maximum Lawful Rate, in
which event this provision shall again apply. In no event shall the total interest received by any Lender exceed the amount which it could lawfully have received had the interest been calculated for the full term hereof at the Maximum Lawful Rate.
If, notwithstanding the prior sentence, any Lender has received interest hereunder in excess of the Maximum Lawful Rate, such excess amount shall be applied to the reduction of the principal balance of the Loans or to other amounts (other than
interest) payable hereunder, and if no such principal or other amounts are then outstanding, such excess or part thereof remaining shall be paid to Borrowers. In computing interest payable with reference to the Maximum Lawful Rate applicable to any
Lender, such interest shall be calculated at a daily rate equal to the Maximum Lawful Rate divided by the number of days in the year in which such calculation is made. 
 Section 2.7 Capital Adequacy. If any Lender shall determine in its commercially reasonable judgment that the adoption or taking effect of, or
any change in, any applicable Law regarding capital adequacy, in each instance, after the Closing Date, or any change after the Closing Date in the interpretation, administration or application thereof by any Governmental Authority, central bank or
comparable agency charged with the interpretation, administration or application thereof, or the compliance by any Lender or any Person controlling such Lender with any request, guideline or directive regarding capital adequacy (whether or not
having the force of law) of any such Governmental Authority, central bank or comparable agency adopted or otherwise taking effect after the Closing Date, has or would have the effect of reducing the rate of return on such Lender’s or such
controlling Person’s capital as a consequence of such Lender’s obligations hereunder or under any Support Agreement or Lender Letter of Credit to a level below that which such Lender or such controlling Person could have achieved but for
such adoption, taking effect, change, interpretation, administration, application or compliance (taking into consideration such Lender’s or such controlling Person’s policies with respect to capital adequacy) then from time to time, upon
written demand by such Lender (which demand shall be accompanied by a statement setting forth the basis for such demand and a calculation of the amount thereof in reasonable detail, a copy of which shall be furnished to Agent), Borrowers shall
promptly pay to such Lender such additional amount as will compensate such Lender or such controlling Person for such reduction, so long as such amounts have accrued on or after the day which is two hundred seventy (270) days prior to the date
on which such Lender first made demand therefor. 
 Section 2.8 Joint and Several Liability. Borrowers are defined collectively
to include all Persons constituting the Borrowers; provided, however, that any references herein to “any Borrower”, “each Borrower” or similar references, shall be construed as a reference to each individual Person named as one
of the Borrowers herein. Each Person so named shall be jointly and severally liable for all of the obligations of Borrowers under this Agreement. Each Borrower, individually, expressly understands, agrees and acknowledges, that the Credit Facilities
would not be made available on the terms herein in the absence of the collective credit of all of the Persons constituting the Borrowers, the joint and several liability of all such Persons, and the cross-collateralization of the collateral of all
such Persons. Accordingly, each Borrower, individually acknowledges that the benefit to each of the Persons comprising the Borrower as a whole constitutes reasonably equivalent value, regardless of the amount of the Credit Facilities actually
borrowed by, advanced to, or the amount of collateral provided by, any individual Borrower. In addition, each entity comprising Borrowers hereby acknowledges and agrees that all of the representations, warranties, covenants, obligations, conditions,
agreements and other terms contained in this Agreement shall be applicable to and shall be binding upon and measured and enforceable individually against each

 Credit and Security Agreement Page 20 

 Person comprising Borrowers as well as all such Persons when taken together. By way of illustration, but without limiting
the generality of the foregoing, the terms of Section 9.1 of this Agreement are to be applied to each individual Person comprising the Borrowers (as well as to all such Persons taken as a whole), such that the occurrence of any of the events
described in Section 9.1 of this Agreement as to any Person comprising the Borrowers shall constitute an Event of Default even if such event has not occurred as to any other Persons comprising the Borrowers or as to all such Persons taken as a
whole. 
 Section 2.9 Collections and Lockbox Account. 
 (a) Borrowers shall maintain a lockbox (the “Lockbox”) with a United States depository institution designated from time to time by Agent
(the “Lockbox Bank”), subject to the provisions of this Agreement, and shall execute with the Lockbox Bank a Deposit Account Control Agreement and such other agreements related to such Lockbox as Agent may require. Borrowers shall
ensure that all collections of Accounts (other than Accounts for which the Account Debtor is a Governmental Account Debtor) are paid directly from Account Debtors into the Lockbox for deposit into the Lockbox Account and/or directly into the Lockbox
Account; provided, however, unless Agent shall otherwise direct by written notice to Borrowers, Borrowers shall be permitted to cause Account Debtors who are individuals to pay Accounts directly to Borrowers, which Borrowers shall then
administer and apply in the manner required below. 
 (b) All funds deposited into a Lockbox Account shall be transferred into the Payment
Account by the close of each Business Day. 
 (c) Notwithstanding anything in any lockbox agreement or Deposit Account Control Agreement to
the contrary, Borrowers agree that they shall be liable for any fees and charges in effect from time to time and charged by the Lockbox Bank in connection with the Lockbox and the Lockbox Account, and that Agent shall have no liability therefor.
Borrowers hereby indemnify and agree to hold Agent harmless from any and all liabilities, claims, losses and demands whatsoever, including reasonable attorneys’ fees and expenses, arising from or relating to actions of Agent or the Lockbox Bank
pursuant to this Section or any lockbox agreement or Deposit Account Control Agreement, but excluding those arising from Agent’s gross negligence or willful misconduct. 
 (d) Agent shall apply, on a daily basis, all funds transferred into the Payment Account pursuant to this Section to reduce the outstanding Revolving
Loans in such order of application as Agent shall elect. If as the result of collections of Accounts pursuant to the terms and conditions of this Section a credit balance exists with respect to the Payment Account, such credit balance shall not
accrue interest in favor of Borrowers, but shall be available to Borrowers upon request of Borrowers at any time or times for so long as no Default exists. 
 (e) To the extent that any collections of Accounts or proceeds of other Collateral are not sent directly to the Lockbox but are received by any Borrower, such collections shall be held in trust for the benefit of
Agent pursuant to an express trust created hereby and immediately remitted, in the form received, to applicable Lockbox and Lockbox Account. No such funds received by any Borrower shall be commingled with other funds of the Borrowers. 
 (f) Borrowers acknowledge and agree that compliance with the terms of this Section is essential, and that Agent and Lenders will suffer immediate
and irreparable injury and have no adequate remedy at law, if any Borrower, through acts or omissions, causes or permits Account Debtors to send payments other than to the Lockbox, or if any Borrower fails to immediately deposit collections of
Accounts or proceeds of other Collateral in the Lockbox Account as herein required. Accordingly, in addition to all other rights and remedies of Agent and Lenders hereunder, Agent shall have the right to seek specific performance of the
Borrowers’ obligations under this Section, and any other equitable relief as Agent may deem necessary or appropriate, and Borrowers waive any requirement for the posting of a bond in connection with such equitable relief. 
 (g) Borrowers shall not, and Borrowers shall not suffer or permit any Credit Party to, (i) withdraw any amounts from any Lockbox Account,
(ii) change the procedures or sweep instructions under the agreements governing any Lockbox Accounts, or (iii) send to or deposit in any Lockbox Account any funds other than payments

 Credit and Security Agreement Page 21 

 made with respect to and proceeds of Accounts or other Collateral. Borrowers shall, and shall cause each Credit Party to,
cooperate with Agent in the identification and reconciliation on a daily basis of all amounts received in or required to be deposited into the Lockbox Accounts. If more than five percent (5%) of the collections of Accounts received by Borrowers
during any given fifteen (15) day period is not identified or reconciled to the reasonable satisfaction of Agent within ten (10) Business Days of receipt, Agent shall not be obligated to make further advances under this Agreement until
such amount is identified or is reconciled to the reasonable satisfaction of Agent, as the case may be. In addition, if any such amount cannot be identified or reconciled to the satisfaction of Agent, Agent may utilize its own staff or, if it deems
necessary, engage an outside auditor, in either case at Borrowers’ expense (which in the case of Agent’s own staff shall be in accordance with Agent’s then prevailing customary charges (plus expenses)), to make such examination
and report as may be necessary to identify and reconcile such amount. 
 (h) If any Borrower breaches its obligation to direct payments of
the proceeds of the Collateral to the Lockbox Account, Agent, as the irrevocably made, constituted and appointed true and lawful attorney for Borrowers, may, by the signature or other act of any of Agent’s officers (without requiring any of
them to do so), direct any Account Debtor to pay proceeds of the Collateral to Borrowers by directing payment to the Lockbox Account. 
 ARTICLE 3 - REPRESENTATIONS AND WARRANTIES 
 To induce Agent and Lenders to enter into this Agreement and to make the Loans
and other credit accommodations contemplated hereby, each Borrower hereby represents and warrants to Agent and each Lender that: 
 Section 3.1 Existence and Power. Each Credit Party is an entity as specified on Schedule 3.1, is duly organized, validly existing and in good standing under the laws of the jurisdiction specified on
Schedule 3.1, has the same legal name as it appears in such Credit Party’s Organizational Documents and an organizational identification number (if any), in each case as specified on Schedule 3.1, and has all powers and
all Permits necessary or desirable in the operation of its business as presently conducted or as proposed to be conducted, except where the failure to have such Permits could not reasonably be expected to have a Material Adverse Effect. Each Credit
Party is qualified to do business as a foreign entity in each jurisdiction in which it is required to be so qualified, which jurisdictions as of the Closing Date are specified on Schedule 3.1, except where the failure to be so qualified
could not reasonably be expected to have a Material Adverse Effect. Except as set forth on Schedule 3.1, no Credit Party (a) has had, over the five (5) year period preceding the Closing Date, any name other than its current
name, or (b) was incorporated or organized under the laws of any jurisdiction other than its current jurisdiction of incorporation or organization. 
 Section 3.2 Organization and Governmental Authorization; No Contravention. The execution, delivery and performance by each Credit Party of the Operative Documents to which it is a party are within its
powers, have been duly authorized by all necessary action pursuant to its Organizational Documents, require no further action by or in respect of, or filing with, any Governmental Authority and do not violate, conflict with or cause a breach or a
default under (a) any Law applicable to any Credit Party or any of the Organizational Documents of any Credit Party, or (b) any agreement or instrument binding upon it, except for such violations, conflicts, breaches or defaults as could
not, with respect to this clause (b), reasonably be expected to have a Material Adverse Effect. 
 Section 3.3 Binding Effect.
Each of the Operative Documents to which any Credit Party is a party constitutes a valid and binding agreement or instrument of such Credit Party, enforceable against such Credit Party in accordance with its respective terms, except as the
enforceability thereof may be limited by bankruptcy, insolvency or other similar laws relating to the enforcement of creditors’ rights generally and by general equitable principles. 
 Section 3.4 Reserved. 
 Section 3.5 Financial Information. All consolidated financial statements for Borrower and any of its

 Credit and Security Agreement Page 22 

 Subsidiaries delivered to Agent fairly present in all material respects Borrower’s consolidated financial condition
and Borrower’s consolidated results of operations. There has not been any material deterioration in Borrower’s consolidated financial condition since the date of the most recent financial statements submitted to Agent. 
 Section 3.6 Litigation. Except as set forth on Schedule 3.6 as of the Closing Date, and except as hereafter disclosed to Agent in
writing, there is no Litigation pending against, or to such Borrower’s knowledge threatened against or affecting, any Credit Party or, to such Borrower’s knowledge, any party to any Operative Document other than a Credit Party. There is no
Litigation pending in which an adverse decision could reasonably be expected to have a Material Adverse Effect or which in any manner draws into question the validity of any of the Operative Documents. 
 Section 3.7 Ownership of Property. Each Borrower and each of its Subsidiaries is the lawful owner of, has good and marketable title to and is
in lawful possession of, or has valid leasehold interests in, all properties and other assets (real or personal, tangible, intangible or mixed) purported or reported to be owned or leased (as the case may be) by such Person. 
 Section 3.8 No Default. No Event of Default, or to such Borrower’s knowledge, Default, has occurred and is continuing. No Credit Party
is in breach or default under or with respect to any contract, agreement, lease or other instrument to which it is a party or by which its property is bound or affected, which breach or default could reasonably be expected to have a Material Adverse
Effect. 
 Section 3.9 Labor Matters. As of the Closing Date, there are no strikes or other labor disputes pending or, to such
Borrower’s knowledge, threatened against any Credit Party. Hours worked and payments made to the employees of the Credit Parties have not been in violation of the Fair Labor Standards Act or any other applicable Law dealing with such matters.
All payments due from the Credit Parties, or for which any claim may be made against any of them, on account of wages and employee and retiree health and welfare insurance and other benefits have been paid or accrued as a liability on their books,
as the case may be. The consummation of the transactions contemplated by the Financing Documents and the other Operative Documents will not give rise to a right of termination or right of renegotiation on the part of any union under any collective
bargaining agreement to which it is a party or by which it is bound. 
 Section 3.10 Regulated Entities. No Credit Party is an
“investment company” or a company “controlled” by an “investment company” or a “subsidiary” of an “investment company,” all within the meaning of the Investment Company Act of 1940. No Credit Party
is a “holding company”, or a “subsidiary company” of a “holding company”, or an “affiliate” of a “holding company” or of a “subsidiary company” of a “holding company”, within the
meaning of the Public Utility Holding Company Act of 1935. 
 Section 3.11 Margin Regulations. None of the proceeds from the
Loans have been or will be used, directly or indirectly, for the purpose of purchasing or carrying any “Margin Stock” (as defined in Regulation U of the Federal Reserve Board), for the purpose of reducing or retiring any indebtedness which
was originally incurred to purchase or carry any “Margin Stock” or for any other purpose which might cause any of the Loans to be considered a “purpose credit” within the meaning of Regulation T, U or X of the Federal Reserve
Board. 
 Section 3.12 Compliance With Laws; Anti-Terrorism Laws. 
 (a) Each Credit Party is in compliance with the requirements of all applicable Laws, except for such Laws the noncompliance with which could not
reasonably be expected to have a Material Adverse Effect. 
 (b) None of the Credit Parties, their Affiliates or any of their respective
agents acting or benefiting in any capacity in connection with the transactions contemplated by this Agreement is (i) in violation of any Anti-Terrorism Law, (ii) engages in or conspires to engage in any transaction that evades or avoids,
or has the purpose of evading or avoiding, or attempts to violate, any of the prohibitions set forth in any Anti-Terrorism Law, or (iii) is a Blocked Person. No Credit Party nor, to the knowledge of any Credit Party, any of its Affiliates or
agents acting or benefiting in any capacity in connection with the transactions contemplated by this Agreement,

the benefit of any Blocked Person, or (y) deals in, or otherwise engages in any transaction relating to, any property or interest in property blocked pursuant to Executive Order No. 13224, any similar executive order or other
Anti-Terrorism Law. 
 Section 3.13 Taxes. All Federal, state and local tax returns, reports and statements required to be filed
by or on behalf of each Credit Party have been filed with the appropriate Governmental Authorities in all jurisdictions in which such returns, reports and statements are required to be filed and, except to the extent subject to a Permitted Contest,
all Taxes (including real property Taxes) and other charges shown to be due and payable in respect thereof have been timely paid prior to the date on which any fine, penalty, interest, late charge or loss may be added thereto for nonpayment thereof.
Except to the extent subject to a Permitted Contest, all state and local sales and use Taxes required to be paid by each Credit Party have been paid. All Federal and state returns have been filed by each Credit Party for all periods for which
returns were due with respect to employee income tax withholding, social security and unemployment taxes, and, except to the extent subject to a Permitted Contest, the amounts shown thereon to be due and payable have been paid in full or adequate
provisions therefor have been made. 
 Section 3.14 Pensions. Borrower has paid all amounts necessary to fund all present
pension, profit sharing and deferred compensation plans in accordance with their terms, and Borrower has not withdrawn from participation in, and has not permitted partial or complete termination of, or permitted the occurrence of any other event
with respect to, any such plan which could reasonably be expected to have a Material Adverse Effect, including any liability to the Pension Benefit Guaranty Corporation or its successors or any other governmental agency. 
 Section 3.15 Material Contracts. Except for the Operative Documents and the other agreements set forth on Schedule 3.15
(collectively with the Operative Documents, the “Material Contracts”), as of the Closing Date there are no (a) employment agreements covering the management of any Credit Party, (b) collective bargaining agreements or
other similar labor agreements covering any employees of any Credit Party, (c) agreements for managerial, consulting or similar services to which any Credit Party is a party or by which it is bound, (d) agreements regarding any Credit

Party is a party, in each case with respect to the preceding clauses (a), (c), (d), (e) and (f) requiring payment by a Credit Party of more than $250,000 in any year, (g) partnership agreements to which any Credit Party is a
general partner or joint venture agreements to which any Credit Party is a party, (h) third party billing arrangements to which any Credit Party is a party, or (i) any other agreements or instruments to which any Credit Party is a party,
and the breach, nonperformance or cancellation of which, or the failure of which to renew, could reasonably be expected to have a Material Adverse Effect. The consummation of the transactions contemplated by the Financing Documents and the other
Operative Documents will not give rise to a right of termination in favor of any party to any Material Contract (other than any Credit Party), except for such Material Contracts the termination of which would not reasonably be expected to have a
Material Adverse Effect.. 
 Section 3.16 Compliance with Environmental Requirements; No Hazardous Materials. 
 Except in each case as set forth on Schedule 3.16: 
 (a) no notice, notification, demand, request for information, citation, summons, complaint or order has been issued, no complaint has been filed, no penalty has been assessed and no investigation or review is pending,

 (b) no property now owned or leased by any Credit Party and, to the knowledge of such Borrower, no such
property previously owned or leased by any Credit Party, to which any Credit Party has, directly or indirectly, transported or arranged for the transportation of any Hazardous Materials, is listed or, to such Borrower’s knowledge, proposed for
listing, on the National Priorities List promulgated pursuant to CERCLA, or CERCLIS (as defined in CERCLA) or any similar state list or is the subject of Federal, state or local enforcement actions or, to the knowledge of such Borrower, other
investigations which may lead to claims against any Credit Party for clean-up costs, remedial work, damage to natural resources or personal injury claims, including, without limitation, claims under CERCLA; 
 For purposes of this Section 3.16, each Credit Party shall be deemed to include any business or business entity (including a corporation) that is, in whole or in
part, a predecessor of such Credit Party. 
 Section 3.17 Intellectual Property. Each Credit Party owns, is licensed to use or
otherwise has the right to use, all Intellectual Property that is material to the condition (financial or other), business or operations of such Credit Party. All such Intellectual Property existing as of the Closing Date and registered with any
United States or foreign Governmental Authority is set forth on Schedule 3.17. All Intellectual Property of each Credit Party is fully protected and/or duly and properly registered, filed or issued in the appropriate office and
jurisdictions for such registrations, filings or issuances, except where the failure to do so would not reasonably be expected to have a Material Adverse Effect. Except as set forth on Schedule 3.17, Borrowers are not a party, nor are
bound by, any material license or other agreement with respect to which any Borrower is the licensee that prohibits or otherwise restricts such Borrower from granting a security interest in such Borrower’s interest in such license or agreement
or other property. To such Borrower’s knowledge, each Credit Party conducts its business without infringement or claim of infringement of any Intellectual Property rights of others and there is no infringement or claim of infringement by others
of any Intellectual Property rights of any Credit Party, which infringement or claim of infringement could reasonably be expected to have a Material Adverse Effect. 
 Section 3.18 Solvency. Each Borrower and each additional Credit Party is Solvent. 
 Section 3.19 Full Disclosure. None of the written information (financial or otherwise) furnished by or on behalf of any Credit Party to Agent or any Lender in connection with the consummation of the transactions contemplated by
the Operative Documents, contains any untrue statement of a material fact or omits to state a material fact necessary to make the statements contained herein or therein not misleading in light of the circumstances under which such statements were
made. All financial projections delivered to Agent and the Lenders by Borrowers (or their agents) have been prepared on the basis of the assumptions stated therein. Such projections represent each Borrower’s best estimate of such
Borrower’s future financial performance and such assumptions are believed by such Borrower to be fair and reasonable in light of current business conditions; provided, however, that Borrowers can give no assurance that such projections
will be attained. 
 Section 3.20 Subsidiaries. Borrowers do not own any stock, partnership interests, limited liability company
interests or other equity securities except for Permitted Investments. 
 Section 3.21 Representations and Warranties Incorporated
from Operative Documents. As of the Closing Date, each of the representations and warranties made in the Operative Documents by each of the parties thereto is true and correct in all material respects, and such representations and warranties are
hereby incorporated herein by reference with the same effect as though set forth in their entirety herein, as qualified therein, except to the extent that such representation or warranty relates to a specific date, in which case such representation
and warranty shall be true as of such earlier date.

 (b) Upon completion of any Permitted Contest, Borrowers shall, and will cause each Subsidiary to, immediately pay the amount due, if any, and deliver to
Agent proof of the completion of the contest and payment of the amount due, if any, following which Agent shall return the security, if any, deposited with Agent pursuant to the definition of Permitted Contest.

with the coverages and rights in favor of Agent and Lenders as described in Schedule 4.4, and (ii) such other insurance coverage in such amounts and with respect to such risks as Agent may reasonably from time to time request. In the
event any Borrower fails to provide Agent with evidence of the insurance coverage required by this Agreement, Agent may purchase insurance at Borrowers’ expense to protect Agent’s interests in the Collateral. 
 Section 4.5 Compliance with Laws. Each Borrower will comply, and cause each Subsidiary to comply, with the requirements of all applicable
Laws, except to the extent that failure to so comply could not reasonably be expected to (a) have a Material Adverse Effect, or (b) result in any Lien upon either (i) a material portion of the assets of any such Person in favor of any

cause each Subsidiary to permit, at the sole cost of the applicable Borrower or any applicable Subsidiary, representatives of Agent and of any Lender (at Borrower’s expense for audits up to four times per year and at Borrower’s expense at
any time that an Event of Default has occurred and is continuing) (but at such Lender’s expense unless such visit or inspection is made concurrently with Agent) to visit and inspect any of their respective properties, to examine and make
abstracts or copies from any of their respective books and records, to conduct a collateral audit and analysis of their respective operations and the Collateral, to verify the amount and age of the Accounts, the identity and credit of the respective
Account Debtors, to review the billing practices of Borrower and to discuss their respective affairs, finances and accounts with their respective officers, employees and independent public accountants as often as may reasonably be desired. In the
absence of an Event of Default, Agent or any Lender exercising any rights pursuant to this Section 4.6 shall give the applicable Borrower or any applicable Subsidiary commercially reasonable prior notice of such exercise. No notice shall be
required during the existence and continuance of any Event of Default.

including, without limitation, verification of Borrowers’ compliance with applicable Laws. Borrowers shall cooperate fully with Agent in an effort to facilitate and promptly conclude such verification process. Such verification may include
contacts between Agent and applicable federal, state and local regulatory authorities having jurisdiction over the Borrowers’ affairs, all of which contacts Borrowers hereby irrevocably authorize.

part of the Collateral, which financing statements may list Agent as the “secured party” and such Borrower as the “debtor” and which describe and indicate the collateral covered thereby as all or any part of the Collateral under
the Financing Documents (including an indication of the collateral covered by any such financing statement as “all assets” of such Borrower now owned or hereafter acquired), in such jurisdictions as Agent from time to time determines are
appropriate, and to file without the signature of such Borrower any continuations of or amendments to any such financing statements, in any such case in order for Agent to perfect, preserve or protect the Liens, rights and remedies of Agent with

any such applicable Law.

Default under this Agreement or the other Financing Documents, Agent, in addition to all other rights, options, and remedies granted to Agent under this Agreement or at law or in equity, may exercise, either directly or through one or more assignees
or designees, all rights and remedies granted to it under all Financing Documents and under the UCC in effect in the applicable jurisdiction(s) and under any other applicable law; including, without limitation: 
 (i) The right to take possession of, send notices regarding, and collect directly the Collateral, with or without judicial process; 
 (ii) The right to (by its own means or with judicial assistance) enter any of Borrowers’ premises and take possession of the Collateral, or
render it unusable, or to render it usable or saleable, or dispose of the Collateral on such premises in compliance with subsection (iii) below and to take possession of Borrowers’ original books and records, to obtain access to
Borrowers’ data processing equipment, computer hardware and software relating to the Collateral and to use all of the foregoing and the information contained therein in any manner Agent deems appropriate, without any liability for rent,
storage, utilities, or other sums, and Borrowers shall not resist or interfere with such action (if Borrowers’ books and records are prepared or maintained by an accounting service, contractor or other third party agent, Borrowers hereby
irrevocably authorize such service, contractor or other agent, upon notice by Agent to such Person that an Event of Default has occurred and is continuing, to deliver to Agent or its designees such books and records, and to follow Agent’s
instructions with respect to further services to be rendered);

address for delivery of Borrowers’ mail to an address designated by Agent and to receive, open and dispose of all mail addressed to any Borrower.

 (b) Each Borrower agrees that a notice received by
it at least ten (10) days before the time of any intended public sale, or the time after which any private sale or other disposition of the Collateral is to be made, shall be deemed to be reasonable notice of such sale or other disposition. If
permitted by applicable law, any perishable Collateral which threatens to speedily decline in value or which is sold on a recognized market may be sold immediately by Agent without prior notice to Borrowers. At any sale or disposition of Collateral,
Agent may (to the extent permitted by applicable law) purchase all or any part of the Collateral, free from any right of redemption by Borrowers, which right is hereby waived and released. Each Borrower covenants and agrees not to interfere with or
impose any obstacle to Agent’s exercise of its rights and remedies with respect to the Collateral. Agent shall have no obligation to clean-up or otherwise prepare the Collateral for sale. Agent may comply with any applicable state or federal
law requirements in connection with a disposition of the Collateral and compliance will not be considered to adversely affect the commercial reasonableness of any sale of the Collateral. Agent may sell the Collateral without giving any warranties as
to the Collateral. Agent may specifically disclaim any warranties of title or the like. This procedure will not be considered to adversely affect the commercial reasonableness of any sale of the Collateral. If Agent sells any of the Collateral upon
credit, Borrowers will be credited only with payments actually made by the purchaser, received by Agent and applied to the indebtedness of the purchaser. In the event the purchaser fails to pay for the Collateral, Agent may resell the Collateral and
Borrowers shall be credited with the proceeds of the sale. Borrowers shall remain liable for any deficiency if the proceeds of any sale or disposition of the Collateral are insufficient to pay all Obligations. 
 (c) Without restricting the generality of the foregoing and for the purposes aforesaid, each Borrower hereby appoints and constitutes Agent its lawful
attorney-in-fact with full power of substitution in the Collateral to use unadvanced funds remaining under this Agreement or which may be reserved, escrowed or set aside for any purposes hereunder at any time, or to advance funds in excess of the
face amount of the Notes, to pay, settle or compromise all existing bills and claims, which may be liens or security interests, or to avoid such bills and claims becoming liens against the Collateral; to execute all applications and certificates in
the name of such Borrower and to prosecute and defend all actions or proceedings in connection with the Collateral; and to do any and every act which such Borrower might do in its own behalf; it being understood and agreed that this power of
attorney shall be a power coupled with an interest and cannot be revoked. 
 (d) Agent and each Lender is hereby granted a non-exclusive,
royalty-free license or other right to use, without charge, Borrowers’ labels, patents, copyrights, mask works, rights of use of any name, trade secrets, trade names, trademarks, service marks, and advertising matter, or any similar property as
it pertains to the Collateral, in completing production of, advertising for sale, and selling any Collateral and, in connection with Agent’s exercise of its rights under this Article, Borrowers’ rights under all licenses and all franchise
agreements inure to Agent’s and each Lender’s benefit.

 Section 9.2 Acceleration and Suspension or Termination of
Revolving Loan Commitment. Upon the occurrence and during the continuance of an Event of Default, Agent may, and shall if requested by Required Lenders, (a) by notice to Borrowers suspend or terminate the Revolving Loan Commitment and the
obligations of Agent and the Lenders with respect thereto, in whole or in part (and, if in part, such reduction shall be pro rata among the Lenders having a Revolving Loan Commitment Percentage), and/or (b) by notice to Borrowers declare the
Obligations to be, and the Obligations shall thereupon become, immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived by each Borrower and Borrowers will pay the same;
provided, however, that in the case of any of the Events of Default specified in Section 9.1(f) or 9.1(g) above, without any notice to any Borrower or any other act by Agent or the Lenders, the Revolving Loan Commitment and the
obligations of Agent and the Lenders with respect thereto shall thereupon terminate and all of the Obligations shall become immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby waived
by each Borrower and Borrowers will pay the same.

from time to time, with reasonably prompt subsequent notice to such Borrower (any prior or contemporaneous notice being hereby expressly waived) to set off and to appropriate and to apply any and all (a) balances held by such Lender or any of
such Lender’s Affiliates at any of its offices for the account of such Borrower or any of its Subsidiaries (regardless of whether such balances are then due to such Borrower or its Subsidiaries), and (b) other property at any time held or
owing by such Lender to or for the credit or for the account of such Borrower or any of its Subsidiaries, against and on account of any of the Obligations; except that no Lender shall exercise any such right without the prior written consent of
Agent. Any Lender exercising a right to set off shall purchase for cash (and the other Lenders shall sell) interests in each of such other Lender’s Pro Rata Share of the Obligations as would be necessary to cause all Lenders to share the amount
so set off with each other Lender in accordance with their respective Pro Rata Share of the Obligations. Each Borrower agrees, to the fullest extent permitted by law, that any Lender and any of such Lender’s Affiliates may exercise its right to
set off with respect to the Obligations as provided in this Section 9.5.

exclusive right to apply and to reapply any and all payments received against the Obligations in such manner as Agent may deem advisable notwithstanding any previous application by Agent, and (b) the proceeds of any sale of, or other
realization upon, all or any part of the Collateral shall be applied: first, to all fees, costs, indemnities, liabilities, obligations and expenses incurred by or owing to Agent with respect to this Agreement, the other Financing Documents or
the Collateral; second, to all fees, costs, indemnities, liabilities, obligations and expenses incurred by

 or owing to any Lender with respect to this Agreement, the other Financing Documents or the Collateral; third, to
accrued and unpaid interest on the Obligations (including any interest which, but for the provisions of the Bankruptcy Code, would have accrued on such amounts); fourth, to the principal amount of the Obligations outstanding; and fifth
to any other indebtedness or obligations of Borrowers owing to Agent or any Lender under the Financing Documents. Any balance remaining shall be delivered to Borrowers or to whoever may be lawfully entitled to receive such balance (including any
holder of the indebtedness evidenced by the Affiliated Financing Documents) or as a court of competent jurisdiction may direct. In carrying out the foregoing, (x) amounts received shall be applied in the numerical order provided until exhausted
prior to the application to the next succeeding category, and (y) each of the Persons entitled to receive a payment in any particular category shall receive an amount equal to its pro rata share of amounts available to be applied pursuant
thereto for such category. 
 Section 9.7 Waivers. 
 (a) Except as otherwise provided for in this Agreement and to the fullest extent permitted by applicable law, each Borrower waives: (i) presentment, demand and protest, and notice of presentment, dishonor, intent
to accelerate, acceleration, protest, default, nonpayment, maturity, release, compromise, settlement, extension or renewal of any or all Financing Documents, the Notes or any other notes, commercial paper, accounts, contracts, documents,
Instruments, Chattel Paper and Guarantees at any time held by Lenders on which any Borrower may in any way be liable, and hereby ratifies and confirms whatever Lenders may do in this regard; (ii) all rights to notice and a hearing prior to
Agent’s or any Lender’s taking possession or control of, or to Agent’s or any Lender’s replevy, attachment or levy upon, any Collateral or any bond or security which might be required by any court prior to allowing Agent or any
Lender to exercise any of its remedies; and (iii) the benefit of all valuation, appraisal and exemption Laws. Each Borrower acknowledges that it has been advised by counsel of its choices and decisions with respect to this Agreement, the other
Financing Documents and the transactions evidenced hereby and thereby. 
 (b) Each Borrower for itself and its successors and assigns,
(i) agrees that its liability shall not be in any manner affected by any indulgence, extension of time, renewal, waiver, or modification granted or consented to by Lender; (ii) consents to any indulgences and all extensions of time,
renewals, waivers, or modifications that may be granted by Agent or any Lender with respect to the payment or other provisions of the Financing Documents, and to any substitution, exchange or release of the Collateral, or any part thereof, with or
without substitution, and agrees to the addition or release of any Borrower, endorsers, guarantors, or sureties, or whether primarily or secondarily liable, without notice to any other Borrower and without affecting its liability hereunder;
(iii) agrees that its liability shall be unconditional and without regard to the liability of any other Borrower, Agent or any Lender for any tax on the indebtedness; and (iv) to the fullest extent permitted by law, expressly waives the
benefit of any statute or rule of law or equity now provided, or which may hereafter be provided, which would produce a result contrary to or in conflict with the foregoing. 
 (c) To the extent that Agent or any Lender may have acquiesced in any noncompliance with any requirements or conditions precedent to the closing of the
Loans or to any subsequent disbursement of Loan proceeds, such acquiescence shall not be deemed to constitute a waiver by Agent or any Lender of such requirements with respect to any future disbursements of Loan proceeds and Agent may at any time
after such acquiescence require Borrowers to comply with all such requirements. Any forbearance by Agent or Lender in exercising any right or remedy under any of the Financing Documents, or otherwise afforded by applicable law, including any failure
to accelerate the maturity date of the Loans, shall not be a waiver of or preclude the exercise of any right or remedy nor shall it serve as a novation of the Notes or as a reinstatement of the Loans or a waiver of such right of acceleration or the
right to insist upon strict compliance of the terms of the Financing Documents. Agent’s or any Lender’s acceptance of payment of any sum secured by any of the Financing Documents after the due date of such payment shall not be a waiver of
Agent’s and such Lender’s right to either require prompt payment when due of all other sums so secured or to declare a default for failure to make prompt payment. The procurement of insurance or the payment of taxes or other liens or
charges by Agent as the result of an Event of Default shall not be a waiver of Agent’s right to accelerate the maturity of the Loans, nor shall Agent’s receipt of any condemnation awards, insurance proceeds, or damages under this Agreement
operate to cure or waive any Credit Party’s default in payment of sums secured by any of the Financing Documents.

 Credit and Security Agreement Page 39 

 (d) Without limiting the generality of anything contained in this Agreement or the other Financing
Documents, each Borrower agrees that if an Event of Default is continuing (i) Agent and Lenders are not subject to any “one action” or “election of remedies” law or rule, and (ii) all Liens and other rights, remedies or
privileges provided to Agent or Lenders shall remain in full force and effect until Agent or Lenders have exhausted all remedies against the Collateral and any other properties owned by Borrowers and the Financing Documents and other security
instruments or agreements securing the Loans have been foreclosed, sold and/or otherwise realized upon in satisfaction of Borrowers’ obligations under the Financing Documents. 
 (e) Nothing contained herein or in any other Financing Document shall be construed as requiring Agent or any Lender to resort to any part of the
Collateral for the satisfaction of any of Borrowers’ obligations under the Financing Documents in preference or priority to any other Collateral, and Agent may seek satisfaction out of all of the Collateral or any part thereof, in its absolute
discretion in respect of Borrowers’ obligations under the Financing Documents. In addition, Agent shall have the right from time to time to partially foreclose upon any Collateral in any manner and for any amounts secured by the Financing
Documents then due and payable as determined by Agent in its sole discretion, including, without limitation, the following circumstances: (i) in the event any Borrower defaults beyond any applicable grace period in the payment of one or more
scheduled payments of principal and/or interest, Agent may foreclose upon all or any part of the Collateral to recover such delinquent payments, or (ii) in the event Agent elects to accelerate less than the entire outstanding principal balance
of the Loans, Agent may foreclose all or any part of the Collateral to recover so much of the principal balance of the Loans as Lender may accelerate and such other sums secured by one or more of the Financing Documents as Agent may elect.
Notwithstanding one or more partial foreclosures, any unforeclosed Collateral shall remain subject to the Financing Documents to secure payment of sums secured by the Financing Documents and not previously recovered. 
 (f) To the fullest extent permitted by law, each Borrower, for itself and its successors and assigns, waives in the event of foreclosure of any or all of
the Collateral any equitable right otherwise available to any Credit Party which would require the separate sale of the any of the Collateral or require Agent or Lenders to exhaust their remedies against any part of the Collateral before proceeding
against any other part of the Collateral; and further in the event of such foreclosure each Borrower does hereby expressly consent to and authorize, at the option of Lender, the foreclosure and sale either separately or together of each part of the
Collateral. 
 Section 9.8 Injunctive Relief. The parties acknowledge and agree that, in the event of a breach or threatened
breach of any Credit Party’s obligations under any Financing Documents, Agent and Lenders may have no adequate remedy in money damages and, accordingly, shall be entitled to an injunction (including without limitation, a temporary restraining
order, preliminary injunction, writ of attachment, or order compelling an audit) against such breach or threatened breach, including, without limitation, maintaining the cash management and collection procedure described herein. However, no
specification in this Agreement of a specific legal or equitable remedy shall be construed as a waiver or prohibition against any other legal or equitable remedies in the event of a breach or threatened breach of any provision of this Agreement.
Each Credit Party waives, to the fullest extent permitted by law, the requirement of the posting of any bond in connection with such injunctive relief. By joining in the Financing Documents as a Credit Party, each Credit Party specifically joins in
this Section as if this Section were a part of each Financing Documents executed by the Credit Party. 
 Section 9.9
Marshalling. Agent and Lenders shall have no obligation to marshal any assets in favor of any Credit Party, or against or in payment of any of the other Obligations or any other obligation owed to Agent or Lenders by any Credit Party.

 ARTICLE 10 - AGENT 
 Section 10.1 Appointment and Authorization. Each Lender hereby irrevocably appoints and authorizes Agent to enter into each of the Financing Documents to which it is a party (other than this Agreement) on its behalf and to take
such actions as Agent on its behalf and to exercise such powers under the Financing Documents as are delegated to Agent by the terms thereof, together with all such powers as are reasonably incidental thereto. Subject to the terms of the other
Financing Documents, Agent is authorized and empowered to amend,

RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 

 Credit and Security Agreement Page 40 

 modify, or waive any provisions of this Agreement or the other Financing Documents on behalf of Lenders. The provisions
of this Article 10 are solely for the benefit of Agent and Lenders and neither any Borrower nor any other Credit Party shall have any rights as a third party beneficiary of any of the provisions hereof. In performing its functions and duties
under this Agreement, Agent shall act solely as agent of Lenders and does not assume and shall not be deemed to have assumed any obligation toward or relationship of agency or trust with or for any Borrower or any other Credit Party. Agent may
perform any of its duties hereunder, or under the Financing Documents, by or through its agents or employees. 
 Section 10.2 Right
to Perform, Preserve and Protect. If any Credit Party fails to perform any obligation hereunder or under any other Financing Document, Agent itself may, but shall not be obligated to, cause such obligation to be performed at Borrowers’
expense. Agent is further authorized by Borrowers and the Lenders to make expenditures from time to time which Agent, in its reasonable business judgment, deems necessary or desirable to (a) preserve or protect the business conducted by
Borrowers, the Collateral, or any portion thereof and/or (b) enhance the likelihood of, or maximize the amount of, repayment of the Loans and other Obligations. Each Borrower hereby agrees to reimburse Agent on demand for any and all costs,
liabilities and obligations incurred by Agent pursuant to this Section 10.2, together with interest thereon at the applicable default rate hereunder. 
 ARTICLE 11 - MISCELLANEOUS 
 Section 11.1 Survival. All agreements, representations and
warranties made herein and in every other Financing Document shall survive the execution and delivery of this Agreement and the other Financing Documents and the other Operative Documents. The provisions of Sections 2.7 and Articles 10 and 11
shall survive the payment of the Obligations (both with respect to any Lender and all Lenders collectively) and any termination of this Agreement. 
 Section 11.2 No Waivers. No failure or delay by Agent or any Lender in exercising any right, power or privilege under any Financing Document shall operate as a waiver thereof nor shall any single or partial exercise thereof
preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein and therein provided shall be cumulative and not exclusive of any rights or remedies provided by law. Any reference
in any Financing Document to the “continuing” nature of any Event of Default shall not be construed as establishing or otherwise indicating that any Borrower or any other Credit Party has the independent right to cure any such Event of
Default, but is rather presented merely for convenience should such Event of Default be waived in accordance with the terms of the applicable Financing Documents. 
 Section 11.3 Notices. 
 (a) All notices, requests and other communications to any party hereunder
shall be in writing (including prepaid overnight courier, facsimile transmission or similar writing) and shall be given to such party at its address, facsimile number or e-mail address set forth on the signature pages hereof (or, in the case of any
such Lender who becomes a Lender after the date hereof, in an Assignment Agreement or in a notice delivered to Borrowers and Agent by the assignee Lender forthwith upon such assignment) or at such other address, facsimile number or e-mail address as
such party may hereafter specify for the purpose by notice to Agent and Borrowers; provided, however, that notices, requests or other communications shall be permitted by electronic means only in accordance with the provisions of
Section 11.3(b) and (c). Each such notice, request or other communication shall be effective (i) if given by facsimile, when such notice is transmitted to the facsimile number specified by this Section and the sender receives a
confirmation of transmission from the sending facsimile machine, or (ii) if given by mail, prepaid overnight courier or any other means, when received or when receipt is refused at the applicable address specified by this Section 11.3(a).

 (b) Notices and other communications to the parties hereto may be delivered or furnished by electronic communication (including e-mail and
Internet or intranet websites) pursuant to procedures approved from time to time by Agent, provided, however, that the foregoing shall not apply to notices sent directly to any Lender if such Lender has notified the Agent that it is
incapable of receiving notices by electronic communication. The Agent

RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 

 Credit and Security Agreement Page 41 

 or Borrowers may, in their discretion, agree to accept notices and other communications to them hereunder by electronic
communications pursuant to procedures approved by it, provided, however, that approval of such procedures may be limited to particular notices or communications. 
 (c) Unless the Agent otherwise prescribes, (i) notices and other communications sent to an e-mail address shall be deemed received upon the
sender’s receipt of an acknowledgment from the intended recipient (such as by the “return receipt requested” function, as available, return e-mail or other written acknowledgment), and (ii) notices or communications posted to an
Internet or intranet website shall be deemed received upon the deemed receipt by the intended recipient at its e-mail address as described in the foregoing clause (i) of notification that such notice or communication is available and
identifying the website address therefor, provided, however, that if any such notice or other communication is not sent or posted during normal business hours, such notice or communication shall be deemed to have been sent at the
opening of business on the next Business Day. 
 Section 11.4 Severability. In case any provision of or obligation under this
Agreement or any other Financing Document shall be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other
jurisdiction, shall not in any way be affected or impaired thereby. 
 Section 11.5 Amendments and Waivers. No provision of this
Agreement or any other Financing Document may be amended, waived or otherwise modified unless such amendment, waiver or other modification is in writing and is signed or otherwise approved by Borrowers, the Agent and the Lenders. 
 Section 11.6 Assignments; Participations. 
 (a) Assignments by Lenders. 
 (i) Each Lender may at any time assign or grant participations in all or any
portion of such Lender’s Loans and interest in the Revolving Loan Commitment, together with all related obligations of such Lender hereunder. Each Lender may at any time pledge or assign a security interest in all or any portion of its rights
under this Agreement to secure obligations of such Lender, including any pledge or assignment to secure obligations to a Federal Reserve Bank; provided, however, that no such pledge or assignment shall release such Lender from any of
its obligations hereunder or substitute any such pledgee or assignee for such Lender as a party hereto. 
 (ii) Agent, acting solely for this
purpose as an agent of Borrowers, shall maintain at its offices located in Chicago, Illinois a copy of each Assignment Agreement delivered to it and a register for the recordation of the names and addresses of each Lender, and the commitments of,
and principal amount of the Loans owing to, such Lender pursuant to the terms hereof. The entries in such register shall be conclusive, and Borrowers, Agent and Lenders may treat each Person whose name is recorded therein pursuant to the terms
hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. Such register shall be available for inspection by any Borrower and any Lender, at any reasonable time upon reasonable prior notice to Agent.

 (b) Credit Party Assignments. No Credit Party may assign, delegate or otherwise transfer any of its rights or other obligations hereunder
or under any other Financing Document without the prior written consent of Agent and each Lender. 
 Section 11.7 Headings.
Headings and captions used in the Financing Documents (including the Exhibits, Schedules and Annexes hereto and thereto) are included for convenience of reference only and shall not be given any substantive effect. 
 Section 11.8 Confidentiality. Agent and each Lender shall hold all non-public information regarding the Credit Parties and their respective
businesses identified as such by Borrowers and obtained by Agent or any

 Lender pursuant to the requirements hereof in accordance with such Person’s customary procedures for handling
information of such nature, except that disclosure of such information may be made (a) to their respective agents, employees, Subsidiaries, Affiliates, attorneys, auditors, professional consultants, rating agencies, insurance industry
associations and portfolio management services, (b) to prospective transferees or purchasers of any interest in the Loans, and to prospective contractual counterparties (or the professional advisors thereto) in swap contracts or other
derivative obligations permitted hereby, provided, however, that any such Persons shall have agreed to be bound by the provisions of this Section 11.8, (c) as required by Law, subpoena, judicial order or similar order and in
connection with any litigation, (d) as may be required in connection with the examination, audit or similar investigation of such Person, and (e) to a Person that is a trustee, investment advisor, collateral manager, servicer, noteholder
or secured party in a Securitization (as hereinafter defined) in connection with the administration, servicing and reporting on the assets serving as collateral for such Securitization. For the purposes of this Section,
“Securitization” shall mean a public or private offering by a Lender or any of its Affiliates or their respective successors and assigns, of securities which represent an interest in, or which are collateralized, in whole or in
party, by the Loans. Confidential information shall include only such information identified as such at the time provided to Agent and shall not include information that either: (i) is in the public domain, or becomes part of the public domain
after disclosure to such Person through no fault of such Person, or (ii) is disclosed to such Person by a Person other than a Credit Party, provided, however, Agent does not have actual knowledge that such Person is prohibited
from disclosing such information. The obligations of Agent and Lenders under this Section 11.8 shall supersede and replace the obligations of Agent and Lenders under any confidentiality agreement in respect of this financing executed and
delivered by Agent or any Lender prior to the date hereof. 
 Section 11.9 Waiver of Consequential and Other Damages. To the
fullest extent permitted by applicable law, no Borrower shall assert, and each Borrower hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or
actual damages) arising out of, in connection with, or as a result of this Agreement, any other Financing Document or any agreement or instrument contemplated hereby or thereby, the transactions contemplated hereby or thereby, any Loan or Letter of
Credit or the use of the proceeds thereof. No Indemnitee shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other
information transmission systems in connection with this Agreement or the other Financing Documents or the transactions contemplated hereby or thereby. 
 Section 11.10 GOVERNING LAW; SUBMISSION TO JURISDICTION. THIS AGREEMENT, EACH NOTE AND EACH OTHER FINANCING DOCUMENT, AND ALL MATTERS RELATING HERETO OR THERETO OR ARISING THEREFROM (WHETHER SOUNDING IN
CONTRACT LAW, TORT LAW OR OTHERWISE), SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF ILLINOIS, WITHOUT REGARD TO CONFLICTS OF LAWS PRINCIPLES. EACH BORROWER HEREBY CONSENTS TO THE JURISDICTION
OF ANY STATE OR FEDERAL COURT LOCATED WITHIN CHICAGO, STATE OF ILLINOIS AND IRREVOCABLY AGREES THAT, SUBJECT TO AGENT’S ELECTION, ALL ACTIONS OR PROCEEDINGS ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE OTHER FINANCING DOCUMENTS SHALL BE
LITIGATED IN SUCH COURTS. EACH BORROWER EXPRESSLY SUBMITS AND CONSENTS TO THE JURISDICTION OF THE AFORESAID COURTS AND WAIVES ANY DEFENSE OF FORUM NON CONVENIENS. EACH BORROWER HEREBY WAIVES PERSONAL SERVICE OF ANY AND ALL PROCESS AND AGREES THAT
ALL SUCH SERVICE OF PROCESS MAY BE MADE UPON SUCH BORROWER BY CERTIFIED OR REGISTERED MAIL, RETURN RECEIPT REQUESTED, ADDRESSED TO SUCH BORROWER AT THE ADDRESS SET FORTH IN THIS AGREEMENT AND SERVICE SO MADE SHALL BE COMPLETE TEN (10) DAYS
AFTER THE SAME HAS BEEN POSTED. 
 Section 11.11 WAIVER OF JURY TRIAL. EACH BORROWER, AGENT AND THE LENDERS HEREBY IRREVOCABLY
WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THE FINANCING DOCUMENTS OR THE TRANSACTIONS CONTEMPLATED THEREBY AND AGREES THAT ANY SUCH ACTION OR PROCEEDING SHALL BE TRIED BEFORE A COURT
AND NOT BEFORE A JURY. EACH BORROWER, AGENT AND EACH LENDER ACKNOWLEDGES THAT THIS WAIVER IS A MATERIAL INDUCEMENT TO ENTER INTO A BUSINESS RELATIONSHIP, THAT EACH HAS RELIED ON THE WAIVER IN

 Credit and Security Agreement Page 43 

 ENTERING INTO THIS AGREEMENT AND THE OTHER FINANCING DOCUMENTS, AND THAT EACH WILL CONTINUE TO RELY ON THIS WAIVER IN
THEIR RELATED FUTURE DEALINGS. EACH BORROWER, AGENT AND EACH LENDER WARRANTS AND REPRESENTS THAT IT HAS HAD THE OPPORTUNITY OF REVIEWING THIS JURY WAIVER WITH LEGAL COUNSEL, AND THAT IT KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS.

 Section 11.12 Publication; Advertisement. 
 (a) Publication. No Credit Party will directly or indirectly publish, disclose or otherwise use in any public disclosure, advertising material, promotional material, press release or interview, any reference to
the name, logo or any trademark of Merrill Lynch or any of its Affiliates or any reference to this Agreement or the financing evidenced hereby, in any case except (i) as required by Law, subpoena or judicial or similar order, in which case the
applicable Credit Party shall give Agent prior written notice of such publication or other disclosure, or (ii) with Merrill Lynch’s prior written consent. 
 (b) Advertisement. Each Lender and each Credit Party hereby authorizes Merrill Lynch to publish the name of such Lender and Credit Party, the existence of the financing arrangements referenced under this
Agreement, the primary purpose and/or structure of those arrangements, the amount of credit extended under each facility, the title and role of each party to this Agreement, and the total amount of the financing evidenced hereby in any
“tombstone”, comparable advertisement or press release which Merrill Lynch elects to submit for publication. In addition, each Lender and each Credit Party agrees that Merrill Lynch may provide lending industry trade organizations with
information necessary and customary for inclusion in league table measurements after the Closing Date. With respect to any of the foregoing, Merrill Lynch shall provide Borrowers with an opportunity to review and confer with Merrill Lynch regarding
the contents of any such tombstone, advertisement or information, as applicable, prior to its submission for publication and, following such review period, Merrill Lynch may, from time to time, publish such information in any media form desired by
Merrill Lynch, until such time that Borrowers shall have requested Merrill Lynch cease any such further publication. 
 Section 11.13
Counterparts; Integration. This Agreement and the other Financing Documents may be signed in any number of counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same
instrument. Signatures by facsimile shall bind the parties hereto. This Agreement and the other Financing Documents constitute the entire agreement and understanding among the parties hereto and supersede any and all prior agreements and
understandings, oral or written, relating to the subject matter hereof. 
 Section 11.14 No Strict Construction. The parties
hereto have participated jointly in the negotiation and drafting of this Agreement. In the event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto and no
presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provisions of this Agreement. 
 Section 11.15 Time. Time is of the essence in each Borrower’s and each other Credit Party’s performance under this Agreement and all other Financing Documents. 
 Section 11.16 Lender Approvals. Unless expressly provided herein to the contrary, any approval, consent, waiver or satisfaction of Agent or
Lenders with respect to any matter that is the subject of this Agreement, the other Financing Documents may be granted or withheld by Agent and Lenders in their sole and absolute discretion and credit judgment. 
 Section 11.17 Cross-Collateralization; Cross-Default. Lender and Borrower are parties to those certain Pfizer Debt Documents (as the same may
from time to time be further amended, modified, supplemented or restated). Both this Agreement and the Pfizer Debt Documents shall continue in full force and effect, and all rights and remedies under this Agreement and the Pfizer Debt Documents are
cumulative. The term “Obligations” as used in this Agreement and the Pfizer Debt Documents shall include without limitation the obligation to pay when due all Loans made pursuant to this Agreement and all interest and finance
charges thereon and the obligation to pay 
  

	[*]  =	CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED AND FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION PURSUANT TO
RULE 24B-2 OF THE SECURITIES EXCHANGE ACT OF 1934, AS AMENDED. 

 Credit and Security Agreement Page 44 

 when due all advances under the Loans (as defined in the Pfizer Debt Documents) (the “Pfizer Loans”)
made pursuant to the Pfizer Debt Documents and all interest and finance charges thereon. Without limiting the generality of the foregoing, all “Collateral” as defined in this Agreement shall secure all Pfizer Loans and all interest and
finance charges thereon and all Loans and all interest and finance charges thereon, and all other Obligations. Any Event of Default under this Agreement shall also constitute an Event of Default under the Pfizer Debt Documents, and any Event of
Default under the Pfizer Debt Documents shall also constitute an Event of Default under this Agreement. In the event the Lender assigns its rights under the Pfizer Debt Documents and/or under any note evidencing Pfizer Loans, to any third party,
whether before or after the occurrence of any Event of Default, the Lender shall have the right (but not any obligation), in its sole discretion, to allocate and apportion Collateral to the Agreement and/or note assigned and to specify the
priorities of the respective security interests in such Collateral between itself and the assignee, all without notice to or consent of the Borrower. 
 Section 11.18 Expenses; Taxes; Indemnity 
 (a) Borrowers agree to pay all reasonable legal, audit
and appraisal fees and all other reasonable out-of-pocket charges and expenses incurred by Agent and Lenders in connection with the negotiation, preparation, legal review and execution of each of the Financing Documents, including but not limited to
UCC and judgment lien searches and UCC filings and fees for post-closing UCC and judgment lien searches. In addition, Borrowers shall pay all such fees and expenses associated with any amendments, modifications and terminations to the Financing
Documents following closing. If Agent uses in-house counsel for any of these purposes, Borrowers further agree that the Obligations include reasonable charges for such work commensurate with the fees that would otherwise be charged by outside legal
counsel selected by Agent for the work performed. 
 (b) Borrowers agree to pay all out-of-pocket charges and expenses incurred by Agent
(including the fees and expenses of Lender’s counsel, advisers and consultants) in connection with the administration, enforcement, protection or preservation of any right or claim of Agent, the termination of this Agreement, the termination of
any Liens of Agent on the Collateral, or the collection of any amounts due under the Financing Documents. If Agent uses in-house counsel for any of these purposes (i.e., for any task in connection with the enforcement, protection or preservation of
any right or claim of Agent and Lenders and the collection of any amounts due under the Financing Documents), Borrowers further agree that the Obligations include reasonable charges for such work commensurate with the fees that would otherwise be
charged by outside legal counsel selected by Agent for the work performed. 
 (c) Borrowers shall pay all taxes (other than taxes based upon
or measured by Agent’s or a Lender’s income or revenues or any personal property tax), if any, in connection with the issuance of the execution of this Agreement, the issuance of the Notes and the recording of any Financing Documents. The
obligations of Borrower under this clause (c) shall survive the payment of Borrowers’ indebtedness under this Agreement and the termination of this Agreement. 
 (d) Borrowers hereby indemnify and agree to defend (with counsel acceptable to Agent) and hold harmless Agent and Lenders, their partners, officers, agents and employees (collectively in the singular,
“Indemnitee”) from and against any liability, loss, cost, expense (including reasonable attorneys’ fees and expenses for both in-house and outside counsel), claim, damage, suit, action or proceeding ever suffered or incurred by
any Indemnitee or in which an Indemnitee may ever be or become involved (whether as a party, witness or otherwise) (a) arising from any Credit Party’s failure to observe, perform or discharge any of its covenants, obligations, agreements
or duties under the Financing Documents, (b) arising from the breach of any of the representations or warranties contained in any Financing Document, (c) by reason of this Agreement, the other Financing Documents or the transactions
contemplated hereby or thereby, or (d) relating to claims of any Person with respect to the Collateral. Notwithstanding any contrary provision in this Agreement, the obligation of Borrower under this Section 11.17 shall survive the payment
in full of the Obligations and the termination of this Agreement. NO INDEMNITEE PERSON SHALL BE RESPONSIBLE OR LIABLE TO THE BORROWERS OR TO ANY OTHER PARTY TO ANY FINANCING DOCUMENT, ANY SUCCESSOR, ASSIGNEE OR THIRD PARTY BENEFICIARY OR ANY OTHER
PERSON ASSERTING CLAIMS DERIVATIVELY THROUGH SUCH PARTY, FOR INDIRECT, PUNITIVE, EXEMPLARY OR CONSEQUENTIAL DAMAGES WHICH MAY BE ALLEGED AS A RESULT OF CREDIT HAVING BEEN EXTENDED, SUSPENDED OR TERMINATED UNDER THIS AGREEMENT OR ANY OTHER FINANCING
DOCUMENT OR AS A RESULT OF ANY OTHER TRANSACTION CONTEMPLATED HEREUNDER OR THEREUNDER.
