All references to “Dollars” or “$” are United States Dollars, unless otherwise noted.
2.LOANS AND TERMS OF PAYMENT
2.1Promise to Pay.  Borrower hereby unconditionally promises to pay each Lender, the outstanding principal amount of all Term Loans advanced to Borrower by such Lender and accrued and unpaid interest thereon and any other amounts due hereunder as and when due in accordance with this Agreement.
2.2Term Loans.
(a)Availability.  
(i)Subject to the terms and conditions of this Agreement, the Lenders agree, severally and not jointly, to make term loans to Borrower on the Effective Date in an aggregate amount of Twenty-Five Million Dollars ($25,000,000.00) according to each Lender’s Term A Loan Commitment as set forth on Schedule 1.1 hereto (such term loans are hereinafter referred to singly as a “Term A Loan”, and collectively as the “Term A Loans”).  After repayment, no Term A Loan may be re-borrowed.
(ii)Subject to the terms and conditions of this Agreement, the Lenders agree, severally and not jointly, during the Second Draw Period, to make term loans to Borrower (but in a single disbursement) in an aggregate amount up to Twenty-Five Million Dollars ($25,000,000.00) according to each Lender’s Term B Loan Commitment as set forth on Schedule 1.1 hereto (such term loans are hereinafter referred to singly as a “Term B Loan”, and collectively as the “Term B Loans”; each Term A Loan or Term B Loan is hereinafter referred to singly as a “Term Loan” and the Term A Loans and the Term B Loans are hereinafter referred to collectively as the “Term Loans”).  After repayment, no Term B Loan may be re-borrowed.
(b)Repayment.  Borrower shall make monthly payments in arrears of interest only commencing on the first (1st) Payment Date following the Funding Date of each Term Loan, and continuing on the Payment Date of each successive month thereafter through and including the Payment Date immediately preceding the Amortization Date.  Borrower agrees to pay, on the Funding Date of each Term Loan, any initial partial monthly interest payment otherwise due for the period between the Funding Date of such Term Loan and the first Payment Date thereof.  Commencing on the Amortization Date, and continuing on the Payment Date of each month thereafter, Borrower shall make consecutive equal monthly payments of principal, together with applicable interest, in arrears, to each Lender, as calculated by Collateral Agent (which calculations shall be deemed correct absent manifest error) based upon: (1) the amount of such Lender’s Term Loan, (2) the effective rate of interest, as determined in 

​

​
​​

Section 2.3(a), and (3) a repayment schedule equal to thirty (30) months.  All unpaid principal and accrued and unpaid interest with respect to each Term Loan is due and payable in full on the Maturity Date.  Each Term Loan may only be prepaid in accordance with Sections 2.2(c) and 2.2(d).
(c)Mandatory Prepayments.  If the Term Loans are accelerated following the occurrence  of an Event of Default (unless such Event of Default has been waived in writing by Collateral Agent and Lenders in their sole discretion), Borrower shall immediately pay to Lenders, payable to each Lender in accordance with its respective Pro Rata Share, an amount equal to the sum of: (i) all outstanding principal of the Term Loans plus accrued and unpaid interest thereon through the prepayment date, (ii) the Final Payment, (iii) the Prepayment Fee, if applicable, plus (iv) all other Obligations that are due and payable, including Lenders’ Expenses and interest at the Default Rate with respect to any past due amounts.  Notwithstanding (but without duplication with) the foregoing, on the Maturity Date, if the Final Payment had not previously been paid in full in connection with the prepayment of the Term Loans in full, Borrower shall pay to Collateral Agent, for payment to each Lender in accordance with its respective Pro Rata Share, the Final Payment in respect of the Term Loan(s).
(d)Permitted Prepayment of Term Loans.  Borrower shall have the option to prepay all, but not less than all, of the Term Loans advanced by the Lenders under this Agreement, provided Borrower (i) provides written notice to Collateral Agent of its election to prepay the Term Loans at least thirty (30) days prior to such prepayment, and (ii) pays to the Lenders on the date of such prepayment, payable to each Lender in accordance with its respective Pro Rata Share, an amount equal to the sum of (A) all outstanding principal of the Term Loans plus accrued and unpaid interest thereon through the prepayment date, (B) the Final Payment, (C) the Prepayment Fee, plus (D) all other Obligations that are due and payable, including Lenders’ Expenses and interest at the Default Rate with respect to any past due amounts.
2.3Payment of Interest on the Credit Extensions.
(a)Interest Rate.  Subject to Section 2.3(b), the principal amount outstanding under the Term Loans shall accrue interest at a floating per annum rate equal to the Basic Rate, determined by Collateral Agent on the Funding Date of the applicable Term Loan, which interest shall be payable monthly in arrears in accordance with Sections 2.2(b) and 2.3(e).  Interest shall accrue on each Term Loan commencing on, and including, the Funding Date of such Term Loan, and shall accrue on the principal amount outstanding under such Term Loan through and including the day on which such Term Loan is paid in full.
(b)Default Rate. Immediately upon the occurrence and during the continuance of an Event of Default, Obligations shall accrue interest at a floating per annum rate equal to the rate that is otherwise applicable thereto plus five percentage points (5.00%) (the “Default Rate”).  Payment or acceptance of the increased interest rate provided in this Section 2.3(b) is not a permitted alternative to timely payment and shall not constitute a waiver of any Event of Default or otherwise prejudice or limit any rights or remedies of Collateral Agent.
(c)360-Day Year.  Interest shall be computed on the basis of a three hundred sixty (360) day year, and the actual number of days elapsed. 
(d)Debit of Accounts.  Collateral Agent and each Lender may debit (or ACH) any deposit accounts (other than deposit accounts exclusively used for payroll, payroll taxes and other employee wage and benefit payments to or for the benefit of Borrower’s employees), maintained by Borrower or any of its Subsidiaries, including the Designated Deposit Account, for principal and interest payments or any other amounts Borrower owes the Lenders under the Loan Documents when due hereunder.  Any such debits (or ACH activity) shall not constitute a set-off.
(e)Payments.  Except as otherwise expressly provided herein, all payments by Borrower under the Loan Documents shall be made to the respective Lender to which such payments are owed, at such Lender’s office in immediately available funds on the date specified herein.  Unless otherwise provided, interest is payable monthly on the Payment Date of each month.  Payments of principal and/or interest received after 2:00 P.M. Eastern time are considered received at the opening of business on the next Business Day.  When a payment is due on a day that is not a Business Day, the payment is due the next Business Day and additional fees or interest, as applicable, shall continue to accrue until paid.  All payments to be made by Borrower hereunder or under any other Loan Document, including 

2

​
​​

payments of principal and interest, 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.
2.4Secured Promissory Notes.  The Term Loans shall be evidenced by a Secured Promissory Note or Notes in the form attached as Exhibit D hereto (each a “Secured Promissory Note”), and shall be repayable as set forth in this Agreement.  Borrower irrevocably authorizes each Lender to make or cause to be made, on or about the Funding Date of any Term Loan or at the time of receipt of any payment of principal on such Lender’s Secured Promissory Note, an appropriate notation on such Lender’s Secured Promissory Note Record reflecting the making of such Term Loan or (as the case may be) the receipt of such payment.  The outstanding amount of each Term Loan set forth on such Lender’s Secured Promissory Note Record shall be prima facie evidence of the principal amount thereof owing and unpaid to such Lender, but the failure to record, or any error in so recording, any such amount on such Lender’s Secured Promissory Note Record shall not limit or otherwise affect Borrower’s obligations under any Secured Promissory Note or any other Loan Document to make payments of principal of or interest on any Secured Promissory Note when due.  Upon receipt of an affidavit of an officer of a Lender as to the loss, theft, destruction, or mutilation of its Secured Promissory Note, Borrower shall issue, in lieu thereof, a replacement Secured Promissory Note in the same principal amount thereof and of like tenor.
2.5Fees.  Borrower shall pay to Collateral Agent:
(a)Facility Fee.  A fully earned, non-refundable facility fee of Two Hundred Fifty Thousand Dollars ($250,000.00) to be shared between the Lenders pursuant to their respective Commitment Percentages payable on the Effective Date;
(b)Final Payment.  The Final Payment, when due hereunder, to be shared between the Lenders in accordance with their respective Pro Rata Shares;
(c)Prepayment Fee.  The Prepayment Fee, if and when due hereunder, to be shared between the Lenders in accordance with their respective Pro Rata Shares; and
(d)Lenders’ Expenses.  All Lenders’ Expenses (including reasonable and documented out-of-pocket attorneys’ fees and expenses for documentation and negotiation of this Agreement) incurred through and after the Effective Date, when due.
(e)Good Faith Deposit.  Borrower has paid to Collateral Agent a deposit of One Hundred Thousand Dollars ($100,000.00) (“Good Faith Deposit”), to initiate Collateral Agent’s and Lenders’ due diligence review and documentation process.  The Good Faith Deposit will be used to pay Lenders’ Expenses due on the Effective Date; provided, however, Borrower shall be responsible for the entire amount of Lenders’ Expenses payable under Section 2.5(c) hereof.
2.6Withholding.  Payments received by the Lenders from Borrower hereunder will be made free and clear of and without deduction for any and all present or future taxes, levies, imposts, duties, deductions, withholdings, assessments, fees or other charges imposed by any governmental authority (including any interest, additions to tax or penalties applicable thereto).  Specifically, however, if at any time any Governmental Authority, applicable law, regulation or international agreement requires Borrower to make any withholding or deduction from any such payment or other sum payable hereunder to the Lenders, Borrower hereby covenants and agrees that the amount due from Borrower with respect to such payment or other sum payable hereunder will be increased to the extent necessary to ensure that, after the making of such required withholding or deduction, each Lender receives a net sum equal to the sum which it would have received had no withholding or deduction been required and Borrower shall pay the full amount withheld or deducted to the relevant Governmental Authority; provided, that Borrower shall not be required to make such increased payment to a Lender who is not a United States Person (as defined in Section 7701(a)(30) of the Internal Revenue Code of 1986, as amended) or who has not provided a duly executed original IRS Form W-9 certifying that such Lender is exempt from U.S. federal backup withholding tax.  Borrower will, upon request, furnish the Lenders with proof reasonably satisfactory to the Lenders indicating that Borrower has made such withholding payment; provided, however, that Borrower need not make any withholding payment if the amount or validity of such withholding payment is contested in good faith by appropriate and timely proceedings and as to which payment in full

​
​​

is bonded or reserved against by Borrower.  The agreements and obligations of Borrower contained in this Section 2.6 shall survive the termination of this Agreement.

Borrower expressly agrees that a Credit Extension made prior to the receipt by Collateral Agent or any Lender of any such item shall not constitute a waiver by Collateral Agent or any Lender of Borrower’s obligation to deliver such item, and any such Credit Extension in the absence of a required item shall be made in each Lender’s sole discretion.

Borrower represents, warrants, and covenants that the security interest granted herein is and shall at all times continue to be a first priority perfected security interest in the Collateral, subject only to Permitted Liens that are permitted by the terms of this Agreement to have priority to Collateral Agent’s Lien.  If Borrower shall acquire a commercial tort claim (as defined in the Code), Borrower, shall promptly notify Collateral Agent in a writing signed by Borrower, as the case may be, of the general details thereof (and further details as may be required by Collateral Agent) and grant to Collateral Agent, for the ratable benefit of the Lenders, in such writing a security interest therein and in the proceeds thereof, all upon the terms of this Agreement, with such writing to be in form and substance reasonably satisfactory to Collateral Agent.

5

​
​​

Borrower acknowledges that it previously has entered, and/or may in the future enter, into Bank Services Agreements with Bank.  Regardless of the terms of any Bank Services Agreement, Borrower agrees that any amounts Borrower owes Bank thereunder shall be deemed to be Obligations hereunder and that it is the intent of Borrower and Bank to have all such Obligations secured by the first priority perfected security interest in the Collateral granted herein (subject only to Permitted Liens that may have superior priority to Collateral Agent’s Lien in this Agreement).
If this Agreement is terminated, Collateral Agent’s Lien in the Collateral shall continue until the Obligations (other than inchoate indemnity obligations) are repaid in full in cash.  Upon payment in full in cash of the Obligations (other than inchoate indemnity obligations) and at such time as the Lenders’ obligation to make Credit Extensions has terminated, Collateral Agent shall, at the sole cost and expense of Borrower, release its Liens in the Collateral and all rights therein shall revert to Borrower.  In the event (x) all Obligations (other than inchoate indemnity obligations), except for Bank Services, are satisfied in full, and (y) this Agreement is terminated, Collateral Agent shall terminate the security interest granted herein upon Borrower providing cash collateral acceptable to Bank in its good faith business judgment for Bank Services, if any.  In the event such Bank Services consist of outstanding Letters of Credit, Borrower shall provide to Bank cash collateral in an amount equal to (x) if such Letters of Credit are denominated in Dollars, then one hundred five percent (105%); and (y) if such Letters of Credit are denominated in a Foreign Currency, then one hundred ten percent (110%), of the Dollar Equivalent of the face amount of all such Letters of Credit, in each case, plus all interest, fees, and costs due or to become due in connection therewith (as estimated by Bank in its good faith business judgment), to secure all of the Obligations relating to such Letters of Credit.
4.2Authorization to File Financing Statements.  Borrower hereby authorizes Collateral Agent to file financing statements or take any other action required to perfect Collateral Agent’s security interests in the Collateral, without notice to Borrower, with all appropriate jurisdictions to perfect or protect Collateral Agent’s interest or rights under the Loan Documents, including a notice that any disposition of the Collateral, except to the extent permitted by the terms of this Agreement, by Borrower, or any other Person, shall be deemed to violate the rights of Collateral Agent under the Code.
4.3Pledge of Collateral.  Borrower hereby pledges, assigns and grants to Collateral Agent, for the ratable benefit of the Lenders, a security interest in all the Shares, together with all proceeds and substitutions thereof, all cash, stock and other moneys and property paid thereon, all rights to subscribe for securities declared or granted in connection therewith, and all other cash and noncash proceeds of the foregoing, as security for the performance of the Obligations.  On the Effective Date, or, to the extent not certificated as of the Effective Date, within ten (10) days of the certification of any Shares, the certificate or certificates for the Shares will be delivered to Collateral Agent, accompanied by an instrument of assignment duly executed in blank by Borrower, and the Perfection Certificates delivered on the Effective Date describe the certificated Shares as of the Effective Date.  To the extent required by the terms and conditions governing the Shares, Borrower shall cause the books of each entity whose Shares are part of the Collateral and any transfer agent to reflect the pledge of the Shares.  Upon the occurrence and during the continuance of an Event of Default hereunder, Collateral Agent may effect the transfer of any securities included in the Collateral (including but not limited to the Shares) into the name of Collateral Agent and cause new (as applicable) certificates representing such securities to be issued in the name of Collateral Agent or its transferee.  Borrower will execute and deliver such documents, and take or cause to be taken such actions, as Collateral Agent may reasonably request to perfect or continue the perfection of Collateral Agent’s security interest in the Shares.  Unless an Event of Default shall have occurred and be continuing, Borrower shall be entitled to exercise any voting rights with respect to the Shares and to give consents, waivers and ratifications in respect thereof, provided that no vote shall be cast or consent, waiver or ratification given or action taken which would be inconsistent with any of the terms of this Agreement or which would constitute or create any violation of any of such terms.  All such rights to vote and give consents, waivers and ratifications shall terminate upon the occurrence and continuance of an Event of Default.

Borrower or any of its Subsidiaries or any Person acting for Borrower or any of its Subsidiaries makes any representation, warranty, or other statement now or later in this Agreement, any Loan Document or in any writing delivered to Collateral Agent and/or Lenders or to induce Collateral Agent and/or the Lenders to enter this Agreement or any Loan Document, and such representation, warranty, or other statement is incorrect in any material respect when made;

(i)settle or adjust disputes and claims directly with Account Debtors for amounts on terms and in any order that Collateral Agent considers advisable, notify any Person owing Borrower money of Collateral Agent’s security interest in such funds, and verify the amount of such account;
(ii)make any payments and do any acts it considers necessary or reasonable to protect the Collateral and/or its security interest in the Collateral.  Borrower shall assemble the Collateral if Collateral Agent requests and make it available in a location  as Collateral Agent reasonably designates.  Collateral Agent may  enter premises where the Collateral is located, take and maintain possession of any part of the Collateral, and pay, purchase, contest, or compromise any Lien which appears to be prior or superior to its security interest and pay all expenses incurred.  Borrower grants Collateral Agent a license to enter and occupy any of its premises, without charge, to exercise any of Collateral Agent’s rights or remedies;
(iii)ship, reclaim, recover, store, finish, maintain, repair, prepare for sale, and/or advertise for sale, the Collateral.  Collateral Agent is hereby granted a non-exclusive, royalty-free license or other right to use, without charge, Borrower’s and each of its Subsidiaries’ 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 Collateral Agent’s exercise of its rights under this Section 9.1, Borrower’s and each of its Subsidiaries’ rights under all licenses and all franchise agreements inure to Collateral Agent, for the benefit of the Lenders;

18

​
​​

Dollar Equivalent of the aggregate face amount of all Letters of Credit remaining undrawn (plus, in each case, all interest, fees, and costs due or to become due in connection therewith (as estimated by Bank in its good faith business judgment)), to secure all of the Obligations relating to such Letters of Credit, as collateral security for the repayment of any future drawings under such Letters of Credit, and Borrower shall forthwith deposit and pay such amounts, and (ii) pay in advance all letter of credit fees scheduled to be paid or payable over the remaining term of any Letters of Credit; and
(ix)terminate any FX Contracts.
Notwithstanding any provision of this Section 9.1 to the contrary, upon the occurrence of any Event of Default, Collateral Agent shall have the right to exercise any and all remedies referenced in this Section 9.1 without the written consent of Required Lenders following the occurrence of an Exigent Circumstance.  As used in the immediately preceding sentence, “Exigent Circumstance” means any event or circumstance that, in the reasonable judgment of Collateral Agent, imminently threatens the ability of Collateral Agent to realize upon all or any material portion of the Collateral, such as, without limitation, fraudulent removal, concealment, or abscondment thereof, destruction or material waste thereof, or failure of Borrower or any of its Subsidiaries after reasonable demand to maintain or reinstate adequate casualty insurance coverage, or which, in the judgment of Collateral Agent, could reasonably be expected to result in a material diminution in value of the Collateral.
9.2Power of Attorney.  Borrower hereby irrevocably appoints Collateral Agent as its lawful attorney-in-fact, exercisable upon the occurrence and during the continuance of an Event of Default, to: (a) endorse Borrower’s or any of its Subsidiaries’ name on any checks or other forms of payment or security; (b) sign Borrower’s or any of its Subsidiaries’ name on any invoice or bill of lading for any Account or drafts against Account Debtors; (c) settle and adjust disputes and claims about the Accounts directly with Account Debtors, for amounts and on terms Collateral Agent determines reasonable; (d) make, settle, and adjust all claims under Borrower’s insurance policies; (e) pay, contest or settle any Lien, charge, encumbrance, security interest, and adverse claim in or to the Collateral, or any judgment based thereon, or otherwise take any action to terminate or discharge the same; and (f) transfer the Collateral into the name of Collateral Agent or a third party as the Code or any applicable law permits.  Borrower hereby appoints Collateral Agent as its lawful attorney-in-fact to sign Borrower’s or any of its Subsidiaries’ name on any documents necessary to perfect or continue the perfection of Collateral Agent’s security interest in the Collateral regardless of whether an Event of Default has occurred until all Obligations (other than inchoate indemnity obligations and Obligations for Bank Services secured by cash collateral in accordance with the terms of Section 4.1 of this Agreement) have been satisfied in full and Collateral Agent and the Lenders are under no further obligation to make Credit Extensions hereunder.  Collateral Agent’s foregoing appointment as Borrower’s or any of its Subsidiaries’ attorney in fact, and all of Collateral Agent’s rights and powers, coupled with an interest, are irrevocable until all Obligations (other than inchoate indemnity obligations and Obligations for Bank Services secured by cash collateral in accordance with the terms of Section 4.1 of this Agreement) have been fully repaid and performed and Collateral Agent’s and the Lenders’ obligation to provide Credit Extensions terminates.
9.3Protective Payments.  If Borrower or any of its Subsidiaries fail to obtain the insurance called for by Section 6.5 or fails to pay any premium thereon or fails to pay any other amount which Borrower or any of its Subsidiaries is obligated to pay under this Agreement or any other Loan Document, Collateral Agent may obtain such insurance or make such payment, and all amounts so paid by Collateral Agent are Lenders’ Expenses and immediately due and payable, bearing interest at the Default Rate, and secured by the Collateral.  Collateral Agent will make reasonable efforts to provide Borrower with notice of Collateral Agent obtaining such insurance or making such payment at the time it is obtained or paid or within a reasonable time thereafter.  No such payments by Collateral Agent are deemed an agreement to make similar payments in the future or Collateral Agent’s waiver of any Event of Default.
9.4Application of Payments and Proceeds.  Notwithstanding anything to the contrary contained in this Agreement, upon the occurrence and during the continuance of an Event of Default, (a) Borrower irrevocably waives the right to direct the application of any and all payments at any time or times thereafter received by Collateral Agent from or on behalf of Borrower or any of its Subsidiaries of all or any part of the Obligations, and, as between Borrower on the one hand and Collateral Agent and Lenders on the other, Collateral Agent shall have the continuing and exclusive right to apply and to reapply any and all payments received against the Obligations in such manner as Collateral Agent may deem advisable notwithstanding any previous application by Collateral Agent, and (b) the 

19

​
​​

proceeds of any sale of, or other realization upon all or any part of the Collateral shall be applied: first, to the Lenders’ Expenses; second, to accrued and unpaid interest on the Obligations (including any interest which, but for the provisions of the United States Bankruptcy Code, would have accrued on such amounts); third, to the principal amount of the Obligations outstanding; and fourth, to any other indebtedness or obligations of Borrower owing to Collateral Agent or any Lender under the Loan Documents.  Any balance remaining shall be delivered to Borrower or to whoever may be lawfully entitled to receive such balance 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.  Any reference in this Agreement to an allocation between or sharing by the Lenders of any right, interest or obligation “ratably,” “proportionally” or in similar terms shall refer to Pro Rata Share unless expressly provided otherwise.  Collateral Agent, or if applicable, each Lender, shall promptly remit to the other Lenders such sums as may be necessary to ensure the ratable repayment of each Lender’s portion of any Term Loan and the ratable distribution of interest, fees and reimbursements paid or made by Borrower.  Notwithstanding the foregoing, a Lender receiving a scheduled payment shall not be responsible for determining whether the other Lenders also received their scheduled payment on such date; provided, however, if it is later determined that a Lender received more than its ratable share of scheduled payments made on any date or dates, then such Lender shall remit to Collateral Agent or other Lenders such sums as may be necessary to ensure the ratable payment of such scheduled payments, as instructed by Collateral Agent.  If any payment or distribution of any kind or character, whether in cash, properties or securities, shall be received by a Lender in excess of its ratable share, then the portion of such payment or distribution in excess of such Lender’s ratable share shall be received by such Lender in trust for and shall be promptly paid over to the other Lender for application to the payments of amounts due on the other Lenders’ claims.  To the extent any payment for the account of Borrower is required to be returned as a voidable transfer or otherwise, the Lenders shall contribute to one another as is necessary to ensure that such return of payment is on a pro rata basis.  If any Lender shall obtain possession of any Collateral, it shall hold such Collateral for itself and as agent and bailee for Collateral Agent and other Lenders for purposes of perfecting Collateral Agent’s security interest therein.
9.5Liability for Collateral.  So long as Collateral Agent and the Lenders comply with  reasonable banking practices regarding the safekeeping of the Collateral in the possession or under the control of Collateral Agent and the Lenders, Collateral Agent and the Lenders shall not be liable or responsible for: (a) the safekeeping of the Collateral; (b) any loss or damage to the Collateral; (c) any diminution in the value of the Collateral; or (d) any act or default of any carrier, warehouseman, bailee, or other Person.  Borrower bears all risk of loss, damage or destruction of the Collateral.
9.6No Waiver; Remedies Cumulative.  Failure by Collateral Agent or any Lender, at any time or times, to require strict performance by Borrower of any provision of this Agreement or any other Loan Document shall not waive, affect, or diminish any right of Collateral Agent or any Lender thereafter to demand strict performance and compliance herewith or therewith.  No waiver hereunder shall be effective unless signed by Collateral Agent and the Required Lenders and then is only effective for the specific instance and purpose for which it is given.  The rights and remedies of Collateral Agent and the Lenders under this Agreement and the other Loan Documents are cumulative.  Collateral Agent and the Lenders have all rights and remedies provided under the Code, any applicable law, by law, or in equity.  The exercise by Collateral Agent or any Lender of one right or remedy is not an election, and Collateral Agent’s or any Lender’s waiver of any Event of Default is not a continuing waiver.  Collateral Agent’s or any Lender’s delay in exercising any remedy is not a waiver, election, or acquiescence.
9.7Demand Waiver.  Borrower waives, to the fullest extent permitted by law, demand, notice of default or dishonor, notice of payment and nonpayment, notice of any default, nonpayment at maturity, release, compromise, settlement, extension, or renewal of accounts, documents, instruments, chattel paper, and guarantees held by Collateral Agent or any Lender on which Borrower or any Subsidiary is liable.

11.CHOICE OF LAW, VENUE AND JURY TRIAL WAIVER
New York law governs the Loan Documents without regard to principles of conflicts of law.  Borrower, Lenders and Collateral Agent each submit to the exclusive jurisdiction of the State and Federal courts in the City of New York, Borough of Manhattan.  NOTWITHSTANDING THE FOREGOING, COLLATERAL AGENT AND THE LENDERS SHALL HAVE THE RIGHT TO BRING ANY ACTION OR PROCEEDING AGAINST BORROWER OR ITS PROPERTY IN THE COURTS OF ANY OTHER JURISDICTION WHICH COLLATERAL AGENT AND THE LENDERS (IN ACCORDANCE WITH THE PROVISIONS OF SECTION 9.1) DEEM NECESSARY OR APPROPRIATE TO REALIZE ON THE COLLATERAL OR TO OTHERWISE ENFORCE COLLATERAL AGENT’S AND THE LENDERS’ RIGHTS AGAINST BORROWER OR ITS PROPERTY.  Borrower expressly submits and consents in advance to such jurisdiction in any action or suit commenced in any such court, and Borrower hereby waives any objection that it may have based upon lack of personal jurisdiction, improper venue, or forum non conveniens and hereby consents to the granting of such legal or equitable relief as is deemed appropriate by such court.  Borrower hereby waives personal service of the summons, complaints, and other process issued in such action or suit and agrees that service of such summons, complaints, and other process may be made by registered or certified mail addressed to Borrower at the address set forth in, or subsequently provided by Borrower in accordance with, Section 10 of this Agreement and that service so made shall be deemed completed upon the earlier to occur of

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, BORROWER, COLLATERAL AGENT, AND THE LENDERS EACH WAIVE THEIR RIGHT TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION ARISING OUT OF OR BASED UPON THIS AGREEMENT, THE LOAN DOCUMENTS OR ANY CONTEMPLATED TRANSACTION, INCLUDING CONTRACT, TORT, BREACH OF DUTY AND ALL OTHER CLAIMS.

12.GENERAL PROVISIONS
12.1Successors and Assigns.  This Agreement binds and is for the benefit of the successors and permitted assigns of each party.  Borrower may not transfer, pledge or assign this Agreement or any rights or obligations under it without Collateral Agent’s and each Lender’s prior written consent (which may be granted or withheld in Collateral Agent’s and each Lender’s discretion, subject to Section 12.6).  The Lenders have the right, without the consent of or notice to Borrower, to sell, transfer, assign, pledge, negotiate, or grant participation in (any such sale, transfer, assignment, negotiation, or grant of a participation, a “Lender Transfer”) all or any part of, or any interest in, the Lenders’ obligations, rights, and benefits under this Agreement and the other Loan Documents; provided, however, that any such Lender Transfer (other than a transfer, pledge, sale or assignment to an Eligible Assignee) of its obligations, rights, and benefits under this Agreement and the other Loan Documents shall require the prior written consent of the Required Lenders (such approved assignee, an “Approved Lender”).  Borrower and Collateral Agent shall be entitled to continue to deal solely and directly with such Lender in connection with the interests so assigned until Collateral Agent shall have received and accepted an effective assignment agreement in form satisfactory to Collateral Agent executed, delivered and fully completed by the applicable parties thereto, and shall have received such other information regarding such Eligible Assignee or Approved Lender as Collateral Agent reasonably shall require.  Notwithstanding anything to the contrary contained herein, so long as no Event of Default has occurred and is continuing, no Lender Transfer (other than a Lender Transfer in connection with (x) assignments by a Lender due to a forced divestiture at the request of any regulatory agency; or (y) upon the occurrence of a default, event of default or similar occurrence with respect to a Lender’s own financing or securitization transactions) shall be permitted, without Borrower’s consent, to any Person which is an Affiliate or Subsidiary of Borrower, a direct competitor of Borrower or a vulture hedge fund, each as  determined by Collateral Agent.
12.2Indemnification.  Borrower agrees to indemnify, defend and hold Collateral Agent and the Lenders and their respective directors, officers, employees, agents, attorneys, or any other Person affiliated with or representing Collateral Agent or the Lenders (each, an “Indemnified Person”) harmless against:  (a) all obligations, demands, claims, and liabilities (collectively, “Claims”) asserted by any other party in connection with; related to; following; or arising from, out of or under, the transactions contemplated by the Loan Documents; and (b) all losses or Lenders’ Expenses incurred, or paid by Indemnified Person in connection with; related to; following; or arising from, out of or under, the transactions contemplated by the Loan Documents between Collateral Agent, and/or the Lenders and Borrower (including reasonable and documented out-of-pocket attorneys’ fees and expenses), except for Claims and/or losses directly caused by such Indemnified Person’s gross negligence or willful misconduct.  Borrower hereby further indemnifies, defends and holds each Indemnified Person harmless from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses and disbursements of any kind or nature whatsoever (including the fees and disbursements of counsel for such Indemnified Person) in connection with any investigative, response, remedial, administrative or judicial matter or proceeding, whether or not such Indemnified Person shall be designated a party thereto and including any such proceeding initiated by or on behalf of Borrower, and the reasonable expenses of investigation by engineers, environmental consultants and similar technical personnel and any commission, fee or compensation claimed by any broker (other than any broker retained by Collateral Agent or Lenders) asserting any right to payment for the transactions contemplated hereby which may be imposed on, incurred by or asserted against such Indemnified Person as a result of or in connection with the transactions contemplated hereby and the use or intended use of the proceeds of the loan proceeds except for liabilities, obligations, losses, damages, penalties, actions, judgments, suits, claims, costs, expenses and disbursements directly caused by such Indemnified Person’s gross negligence or willful misconduct.

In the event of such objection, such correction shall not be made except by an amendment signed by Collateral Agent, the Lenders, and Borrower.
12.6Amendments in Writing; Integration.  (a) No amendment, modification, termination or waiver of any provision of this Agreement or any other Loan Document, no approval or consent thereunder, or any consent to any departure by Borrower or any of its Subsidiaries therefrom, shall in any event be effective unless the same shall be in writing and signed by Borrower, Collateral Agent and the Required Lenders provided that:
(i)no such amendment, waiver or other modification that would have the effect of increasing or reducing a Lender’s Term Loan Commitment or Commitment Percentage shall be effective as to such Lender without such Lender’s written consent;
(ii)no such amendment, waiver or modification that would affect the rights and duties of Collateral Agent shall be effective without Collateral Agent’s written consent or signature;

It is hereby understood and agreed that all Lenders shall be deemed directly affected by an amendment, waiver or other modification of the type described in the preceding clauses (C), (D), (E), (F), (G) and (H) of the preceding sentence;
(iv)the provisions of the foregoing clauses (i), (ii) and (iii) are subject to the provisions of any interlender or agency agreement among the Lenders and Collateral Agent pursuant to which any Lender may agree to give its consent in connection with any amendment, waiver or modification of the Loan Documents only in the event of the unanimous agreement of all Lenders.
(b)Other than as expressly provided for in Section 12.6(a)(i)-(iii), Collateral Agent may, if requested by the Required Lenders, from time to time designate covenants in this Agreement less restrictive by notification to a representative of Borrower.

​
​​

12.8Survival.  All covenants, representations and warranties made in this Agreement continue in full force and effect until this Agreement has terminated pursuant to its terms and all Obligations (other than inchoate indemnity obligations and any other obligations which, by their terms, are to survive the termination of this Agreement) have been satisfied.  Without limiting the foregoing, except as otherwise provided in Section 4.1, the grant of security interest by Borrower in Section 4.1 shall survive until the termination of all Bank Services Agreements.

EXHIBIT A

Description of Collateral
The Collateral consists of all of Borrower’s right, title and interest in and to the following personal property:
All goods, Accounts (including health-care receivables), Equipment, Inventory, contract rights or rights to payment of money, leases, license agreements, franchise agreements, General Intangibles (except as noted below), commercial tort claims, documents, instruments (including any promissory notes), chattel paper (whether tangible or electronic), cash, deposit accounts and other Collateral Accounts, all certificates of deposit, fixtures, letters of credit rights (whether or not the letter of credit is evidenced by a writing), securities, and all other investment property, supporting obligations, and financial assets, whether now owned or hereafter acquired, wherever located; and
All Borrower’s Books relating to the foregoing, and any and all claims, rights and interests in any of the above and all substitutions for, additions, attachments, accessories, accessions and improvements to and replacements, products, proceeds and insurance proceeds of any or all of the foregoing.
Notwithstanding the foregoing, the Collateral does not include (i) any Equipment or other property financed by a third party, provided that such third party’s Liens are Liens of the type described in subsection (c) of the definition of Permitted Liens if the granting of a Lien in such Equipment or other property financed is prohibited by or would constitute a default under any agreement or document governing such Equipment or property financed; provided that the aggregate value of all such Equipment or property financed does not exceed Five Hundred Thousand Dollars ($500,000.00); provided further that upon the termination, lapsing or expiration of any such prohibition, such Equipment or other property financed, as applicable, shall automatically be subject to the security interest granted in favor of Collateral Agent hereunder and become part of the “Collateral”; (ii) any lease, license or contract, in each case if the granting of a Lien in such lease, license or contract is prohibited by or would constitute a default under the agreement governing such lease, license or contract (but (A) only to the extent such prohibition is enforceable under applicable law and (B) other than to the extent that any such term would be rendered ineffective pursuant to Sections 9-406, 9-408 or 9-409 (or any other Section) of Article 9 of the Code); provided that upon the termination, lapsing or expiration of any such prohibition, such lease, license or contract, as applicable, shall automatically be subject to the security interest granted in favor of Collateral Agent hereunder and become part of the “Collateral”; and (iii) any Intellectual Property; provided, however, the Collateral shall include all Accounts and all proceeds of Intellectual Property.  If a judicial authority (including a U.S. Bankruptcy Court) would hold that a security interest in the underlying Intellectual Property is necessary to have a security interest in such Accounts and such property that are proceeds of Intellectual Property, then the Collateral shall automatically, and effective as of the Effective Date, include the Intellectual Property to the extent necessary to permit perfection of Collateral Agent’s security interest in such Accounts and such other property of Borrower that are proceeds of the Intellectual Property.
Pursuant to the terms of a certain negative pledge arrangement with Collateral Agent and the Lenders, Borrower has agreed not to encumber any of its Intellectual Property.

FOR VALUE RECEIVED, the undersigned, SCHOLAR ROCK HOLDING CORPORATION, a Delaware corporation (“Parent”) and SCHOLAR ROCK, INC., a Delaware corporation (together with Parent, individually and collectively, jointly and severally, “Borrower”) with an office located at 620 Memorial Drive, 2nd Floor, Cambridge, MA 02139 (“Borrower”) HEREBY PROMISES TO PAY to the order of [OXFORD FINANCE LLC][SILICON VALLEY BANK] (“Lender”) the principal amount of [___________] MILLION DOLLARS ($______________) or such lesser amount as shall equal the outstanding principal balance of the Term [A][B] Loan made to Borrower by Lender, plus interest on the aggregate unpaid principal amount of such Term [A][B] Loan, at the rates and in accordance with the terms of the Loan and Security Agreement dated October 16, 2020 by and among Borrower, Lender, Oxford Finance LLC, as Collateral Agent, and the other Lenders from time to time party thereto (as amended, restated, supplemented or otherwise modified from time to time, the “Loan Agreement”).  If not sooner paid, the entire principal amount and all accrued and unpaid interest hereunder shall be due and payable on the Maturity Date as set forth in the Loan Agreement.  Any capitalized term not otherwise defined herein shall have the meaning attributed to such term in the Loan Agreement.
Principal, interest and all other amounts due with respect to the Term [A][B] Loan, are payable in lawful money of the United States of America to Lender as set forth in the Loan Agreement and this Secured Promissory Note (this “Note”).  The principal amount of this Note and the interest rate applicable thereto, and all payments made with respect thereto, shall be recorded by Lender and, prior to any transfer hereof, endorsed on the grid attached hereto which is part of this Note.
The Loan Agreement, among other things, (a) provides for the making of a secured Term [A][B] Loan by Lender to Borrower, and (b) contains provisions for acceleration of the maturity hereof upon the happening of certain stated events.

This Note shall be governed by, and construed and interpreted in accordance with, the internal laws of the State of New York.
The ownership of an interest in this Note shall be registered on a record of ownership maintained by Lender or its agent.  Notwithstanding anything else in this Note to the contrary, the right to the principal of, and stated interest on, this Note may be transferred only if the transfer is registered on such record of ownership and the transferee is identified as the owner of an interest in the obligation.  Borrower shall be entitled to treat the registered holder of this Note (as recorded on such record of ownership) as the owner in fact thereof for all purposes and shall not be bound to recognize any equitable or other claim to or interest in this Note on the part of any other person or entity.

DEBTOR:SCHOLAR ROCK HOLDING CORPORATION and SCHOLAR ROCK, INC.
SECURED PARTY:OXFORD FINANCE LLC, as Collateral Agent
EXHIBIT A TO UCC FINANCING STATEMENT

Description of Collateral
The Collateral consists of all of Debtor’s right, title and interest in and to the following personal property:
All goods, Accounts (including health-care receivables), Equipment, Inventory, contract rights or rights to payment of money, leases, license agreements, franchise agreements, General Intangibles (except as noted below), commercial tort claims, documents, instruments (including any promissory notes), chattel paper (whether tangible or electronic), cash, deposit accounts and other Collateral Accounts, all certificates of deposit, fixtures, letters of credit rights (whether or not the letter of credit is evidenced by a writing), securities, and all other investment property, supporting obligations, and financial assets, whether now owned or hereafter acquired, wherever located; and
All Borrower’s Books relating to the foregoing, and any and all claims, rights and interests in any of the above and all substitutions for, additions, attachments, accessories, accessions and improvements to and replacements, products, proceeds and insurance proceeds of any or all of the foregoing.
Notwithstanding the foregoing, the Collateral does not include (i) any Equipment or other property financed by a third party, provided that such third party’s Liens are Liens of the type described in subsection (c) of the definition of Permitted Liens if the granting of a Lien in such Equipment or other property financed is prohibited by or would constitute a default under any agreement or document governing such Equipment or property financed; provided that the aggregate value of all such Equipment or property financed does not exceed Five Hundred Thousand Dollars ($500,000.00); provided further that upon the termination, lapsing or expiration of any such prohibition, such Equipment or other property financed, as applicable, shall automatically be subject to the security interest granted in favor of Collateral Agent hereunder and become part of the “Collateral”; (ii) any lease, license or contract, in each case if the granting of a Lien in such lease, license or contract is prohibited by or would constitute a default under the agreement governing such lease, license or contract (but (A) only to the extent such prohibition is enforceable under applicable law and (B) other than to the extent that any such term would be rendered ineffective pursuant to Sections 9-406, 9-408 or 9-409 (or any other Section) of Article 9 of the Code); provided that upon the termination, lapsing or expiration of any such prohibition, such lease, license or contract, as applicable, shall automatically be subject to the security interest granted in favor of Secured Party hereunder and become part of the “Collateral”; and (iii) any Intellectual Property; provided, however, the Collateral shall include all Accounts and all proceeds of Intellectual Property.  If a judicial authority (including a U.S. Bankruptcy Court) would hold that a security interest in the underlying Intellectual Property is necessary to have a security interest in such Accounts and such property that are proceeds of Intellectual Property, then the Collateral shall automatically, and effective as of the Effective Date, include the Intellectual Property to the extent necessary to permit perfection of Collateral Agent’s security interest in such Accounts and such other property of Debtor that are proceeds of the Intellectual Property.
Pursuant to the terms of a certain negative pledge arrangement with Collateral Agent and the Lenders, Debtor has agreed not to encumber any of its Intellectual Property.
Capitalized terms used but not defined herein have the meanings ascribed in the Uniform Commercial Code in effect in the State of New York as in effect from time to time (the “Code”) or, if not defined in the Code, then in the Loan and Security Agreement by and between Debtor, Secured Party and the other Lenders party thereto (as modified, amended and/or restated from time to time).

EMPLOYMENT AGREEMENT
This Employment Agreement (“Agreement”) is made as of the 23rd day of May, 2018, between Scholar Rock, Inc., a Delaware corporation (the “Company”), and Gregory Carven (the “Employee”) and is effective as of the closing of the Company’s first underwritten public offering of its equity securities pursuant to an effective registration statement under the Securities Act of 1933, as amended (the “Effective Date”).
WHEREAS, the Company and the Employee are parties to an offer letter, dated October 21, 2014 (the “Prior Agreement”); and
WHEREAS, the parties intend to replace the Prior Agreement with this Agreement, effective as of the Effective Date.
NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:
1.Employment.
(a)Term.  The term of this Agreement shall commence on the Effective Date and continue until terminated in accordance with the provisions hereof (the “Term”).  The Employee’s employment with the Company will continue to be “at will,” meaning that the Employee’s employment may be terminated by the Company or the Employee at any time and for any reason subject to the terms of this Agreement. 
(b)Position and Duties.  During the Term, the Employee shall serve as the Senior Vice President, Antibody Discovery, of the Company, and shall have such duties and authorities as may from time to time be prescribed by the Chief Executive Officer of the Company (the “CEO”), Chief Scientific Officer, or other executive designated by the CEO.  The Employee shall devote his full working time and efforts to the business and affairs of the Company.  Notwithstanding the foregoing, the Employee may serve on other boards of directors, with the approval of the CEO, or engage in religious, charitable or other community activities as long as such services and activities do not materially interfere with the Executive’s performance of his duties to the Company as provided in this Agreement.
2.Compensation and Related Matters.
(a)Base Salary.  During the Term, the Employee’s annual base salary shall be $329,000.  The Employee’s base salary shall be reviewed annually by the Compensation Committee of the Board (the “Compensation Committee”) or the CEO.  The base salary in effect at any given time is referred to herein as “Base Salary.”  The Base Salary shall be payable in a manner that is consistent with the Company’s usual payroll practices.

(b)Incentive Compensation.  During the Term, the Employee shall be eligible to receive cash incentive compensation as determined by the Board or the Compensation Committee from time to time.  The Employee’s initial target annual incentive compensation shall be thirty-five percent (35%) of his Base Salary (the “Target Annual Incentive Compensation”).  Except as otherwise provided herein, to earn incentive compensation, the Employee must be employed by the Company on the day such incentive compensation is paid.
(c)Expenses.  The Employee shall be entitled to receive prompt reimbursement for all reasonable expenses incurred by him during the Term in performing services hereunder, in accordance with the policies and procedures then in effect and established by the Company.
(d)Other Benefits.  During the Term, the Employee shall be eligible to participate in or receive benefits under the Company’s employee benefit plans in effect from time to time, subject to the terms of such plans.
(e)Vacations.  During the Term, the Employee shall be entitled to paid vacation in accordance with the Company’s policies and procedures.  The Employee shall also be entitled to all paid holidays given by the Company in accordance with the policies and procedures then in effect and established by the Company.
3.Termination.  During the Term, the Employee’s employment hereunder may be terminated without any breach of this Agreement under the following circumstances:
(a)Death.  The Employee’s employment hereunder shall terminate upon his death.
(b)Termination by Company for Cause.  The Company may terminate the Employee’s employment hereunder for Cause.  For purposes of this Agreement, “Cause” shall mean:  (i) conduct by the Employee constituting a material act of misconduct in connection with the performance of his duties, including, without limitation, misappropriation of funds or property of the Company or any of its subsidiaries or affiliates other than the occasional, customary and de minimis use of Company property for personal purposes; (ii) the commission by the Employee of any felony or a misdemeanor involving moral turpitude, deceit, dishonesty or fraud, or any conduct by the Employee that would reasonably be expected to result in material injury or reputational harm to the Company or any of its subsidiaries or affiliates if he were retained in his position; (iii) continued non-performance by the Employee of his duties hereunder (other than by reason of the Employee’s physical or mental illness, incapacity or disability) which has continued for more than 30 days following written notice of such non-performance from the CEO; (iv) a breach by the Employee of any of the provisions contained in Section 7 of this Agreement; (v) a material violation by the Employee of the Company’s written employment policies; or (vi) failure to cooperate with a bona fide internal investigation or an investigation by regulatory or law enforcement authorities, after being instructed by the Company to cooperate, or the willful destruction or failure to preserve documents or other materials known to be relevant to such investigation or the inducement of others to fail to cooperate or to produce documents or other materials in connection with such investigation.

​

​

(c)Termination Without Cause.  The Company may terminate the Employee’s employment hereunder at any time without Cause.  Any termination by the Company of the Employee’s employment under this Agreement which does not constitute a termination for Cause under Section 3(b) and does not result from the death of the Employee under Section 3(a) shall be deemed a termination without Cause.
(d)Termination by the Employee.  The Employee may terminate his employment hereunder at any time for any reason, including but not limited to Good Reason.  For purposes of this Agreement, “Good Reason” shall mean that the Employee has complied with the “Good Reason Process” (hereinafter defined) following the occurrence of any of the following events:  (i) a material diminution in the Employee’s responsibilities, authority or duties; (ii) a material diminution in the Employee’s Base Salary except for across-the-board salary reductions based on the Company’s financial performance similarly affecting all or substantially all senior management employees of the Company; (iii) a material change in the geographic location at which the Employee provides services to the Company, except for required travel for the Company’s business; or (iv) the material breach of this Agreement by the Company.  “Good Reason Process” shall mean that (i) the Employee reasonably determines in good faith that a “Good Reason” condition has occurred; (ii) the Employee notifies the Company in writing of the first occurrence of the Good Reason condition within 60 days of the first occurrence of such condition; (iii) the Employee cooperates in good faith with the Company’s efforts, for a period not less than 30 days following such notice (the “Cure Period”), to remedy the condition; (iv) notwithstanding such efforts, the Good Reason condition continues to exist; and (v) the Employee terminates his employment within 60 days after the end of the Cure Period.  If the Company cures the Good Reason condition during the Cure Period, Good Reason shall be deemed not to have occurred.
(e)Notice of Termination.  Except for termination as specified in Section 3(a), any termination of the Employee’s employment by the Company or any such termination by the Employee shall be communicated by written Notice of Termination to the other party hereto.  For purposes of this Agreement, a “Notice of Termination” shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon.
(f)Date of Termination.  “Date of Termination” shall mean:  (i) if the Employee’s employment is terminated by his death, the date of his death; (ii) if the Employee’s employment is terminated by the Company under Section 3(c), the date on which a Notice of Termination is given; (iii) if the Employee’s employment is terminated by the Employee under Section 3(d) without Good Reason, 30 days after the date on which a Notice of Termination is given, and (iv) if the Employee’s employment is terminated by the Employee under Section 3(d) with Good Reason, the date on which a Notice of Termination is given after the end of the Cure Period.  Notwithstanding the foregoing, in the event that the Employee gives a Notice of Termination to the Company, the Company may unilaterally accelerate the Date of Termination and such acceleration shall not result in a termination by the Company for purposes of this Agreement.

4.Compensation Upon Termination.
(a)Termination Generally.  If the Employee’s employment with the Company is terminated for any reason, the Company shall pay or provide to the Employee (or to his authorized representative or estate) (i) any Base Salary earned through the Date of Termination, unpaid expense reimbursements (subject to, and in accordance with, Section 2(c) of this Agreement) and unused vacation that accrued through the Date of Termination on or before the time required by law but in no event more than 30 days after the Employee’s Date of Termination; and (ii) any vested benefits the Employee may have under any employee benefit plan of the Company through the Date of Termination, which vested benefits shall be paid and/or provided in accordance with the terms of such employee benefit plans (collectively, the “Accrued Benefit”).
(b)Termination by the Company Without Cause or by the Employee with Good Reason.  During the Term, if the Employee’s employment is terminated by the Company without Cause as provided in Section 3(c), or the Employee terminates his employment for Good Reason as provided in Section 3(d), then the Company shall pay the Employee his Accrued Benefit.  In addition, subject to the Employee signing a separation agreement containing, among other provisions, a general release of claims in favor of the Company and related persons and entities, confidentiality, return of property and non-disparagement, in a form and manner satisfactory to the Company (the “Separation Agreement and Release”) and the Separation Agreement and Release becoming irrevocable and fully effective, all within 60 days after the Date of Termination (or such shorter time period provided in the Separation Agreement and Release):
(i)the Company shall pay the Employee an amount equal to 9 months of the Employee’s Base Salary (the “Severance Amount”).  Notwithstanding the foregoing, if the Employee breaches any of the provisions contained in Section 7 of this Agreement, all payments of the Severance Amount shall immediately cease; 
(ii)RESERVED
(iii)if the Employee was participating in the Company’s group health plan immediately prior to the Date of Termination and elects COBRA health continuation, then the Company shall pay to the Employee a monthly cash payment for 9 months or the Employee’s COBRA health continuation period, whichever ends earlier, in an amount equal to the monthly employer contribution that the Company would have made to provide health insurance to the Employee if the Employee had remained employed by the Company; and
(iv)the amounts payable under Section 4(b)(i) and (iii) shall be paid out in substantially equal installments in accordance with the Company’s payroll practice commencing within 60 days after the Date of Termination; provided, however, that if the 60-day period begins in one calendar year and ends in a second calendar year, the Severance Amount shall begin to be paid in the second calendar year by the last day of such 60-day period; provided, further, that the initial payment shall include a catch-up payment to cover amounts retroactive to the day immediately following the Date of

Termination.  Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2).
5.Change in Control Payment.  The provisions of this Section 5 set forth certain terms of an agreement reached between the Employee and the Company regarding the Employee’s rights and obligations upon the occurrence of a Change in Control of the Company.  These provisions are intended to assure and encourage in advance the Employee’s continued attention and dedication to his assigned duties and his objectivity during the pendency and after the occurrence of any such event.  These provisions shall apply in lieu of, and expressly supersede, the provisions of Section 4(b) regarding severance pay and benefits upon a termination of employment, if such termination of employment occurs within 18 months after the occurrence of the first event constituting a Change in Control.  These provisions shall terminate and be of no further force or effect beginning 18 months after the occurrence of a Change in Control.
(a)Change in Control.  During the Term, if within 18 months after a Change in Control, the Employee’s employment is terminated by the Company without Cause as provided in Section 3(c) or the Employee terminates his employment for Good Reason as provided in Section 3(d), then, subject to the signing of the Separation Agreement and Release by the Employee and the Separation Agreement and Release becoming irrevocable and fully effective, all within 60 days after the Date of Termination (or such shorter time period provided in the Separation Agreement and Release): 
(i)the Company shall pay the Employee a lump sum in cash in an amount equal to 1.0 times the sum of (A) the Employee’s current Base Salary (or the Employee’s Base Salary in effect immediately prior to the Change in Control, if higher) plus (B) the Employee’s Average Incentive Compensation (For purposes of this Agreement, “Average Incentive Compensation” shall mean the Target Annual Incentive Compensation the Employee would have been entitled to receive in the fiscal year of termination (or the Employee’s Target Annual Incentive Compensation in the fiscal year immediately prior to the Change in Control, if higher).  In no event shall “Average Incentive Compensation” include any sign-on bonus, retention bonus or any other special bonus.); 
(ii)notwithstanding anything to the contrary in any applicable option agreement or stock-based award agreement, all time-based stock options and other time-based stock-based awards held by the Employee shall immediately accelerate and become fully exercisable or nonforfeitable as of the Date of Termination; 
(iii)if the Employee was participating in the Company’s group health plan immediately prior to the Date of Termination and elects COBRA health continuation, then the Company shall pay to the Employee a monthly cash payment for 12 months or the Employee’s COBRA health continuation period, whichever ends earlier, in an amount equal to the monthly employer contribution that the Company would have made to provide health insurance to the Employee if the Employee had remained employed by the Company; and

​

(iv)The amounts payable under Section 5(a)(i) and (iii) shall be paid or commence to be paid within 60 days after the Date of Termination; provided, however, that if the 60-day period begins in one calendar year and ends in a second calendar year, such payment shall be paid or commence to be paid in the second calendar year by the last day of such 60-day period.
(b)Additional Limitation.
(i)Anything in this Agreement to the contrary notwithstanding, in the event that the amount of any compensation, payment or distribution by the Company to or for the benefit of the Employee, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, calculated in a manner consistent with Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”) and the applicable regulations thereunder (the “Aggregate Payments”), would be subject to the excise tax imposed by Section 4999 of the Code, then the Aggregate Payments shall be reduced (but not below zero) so that the sum of all of the Aggregate Payments shall be $1.00 less than the amount at which the Employee becomes subject to the excise tax imposed by Section 4999 of the Code; provided that such reduction shall only occur if it would result in the Employee receiving a higher After Tax Amount (as defined below) than the Employee would receive if the Aggregate Payments were not subject to such reduction.  In such event, the Aggregate Payments shall be reduced in the following order, in each case, in reverse chronological order beginning with the Aggregate Payments that are to be paid the furthest in time from consummation of the transaction that is subject to Section 280G of the Code: (1) cash payments not subject to Section 409A of the Code; (2) cash payments subject to Section 409A of the Code; (3) equity-based payments and acceleration; and (4) non-cash forms of benefits; provided that in the case of all the foregoing Aggregate Payments all amounts or payments that are not subject to calculation under Treas. Reg. §1.280G-1, Q&A-24(b) or (c) shall be reduced before any amounts that are subject to calculation under Treas. Reg. §1.280G-1, Q&A-24(b) or (c).
(ii)For purposes of this Section 5(b), the “After Tax Amount” means the amount of the Aggregate Payments less all federal, state, and local income, excise and employment taxes imposed on the Employee as a result of the Employee’s receipt of the Aggregate Payments.  For purposes of determining the After Tax Amount, the Employee shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation applicable to individuals for the calendar year in which the determination is to be made, and state and local income taxes at the highest marginal rates of individual taxation in each applicable state and locality, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes. 
(iii)The determination as to whether a reduction in the Aggregate Payments shall be made pursuant to Section 5(b)(i) shall be made by a nationally recognized accounting firm selected by the Company (the “Accounting Firm”), which shall provide detailed supporting calculations both to the Company and the Employee within 15 business days of the Date of Termination, if applicable, or at such earlier time

​

as is reasonably requested by the Company or the Employee.  Any determination by the Accounting Firm shall be binding upon the Company and the Employee.
(c)Definitions.  For purposes of this Section 5, the following terms shall have the following meanings:
“Change in Control” shall mean any of the following:
(i)any “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Act”) (other than the Company, any of its subsidiaries, or any trustee, fiduciary or other person or entity holding securities under any employee benefit plan or trust of the Company or any of its subsidiaries), together with all “affiliates” and “associates” (as such terms are defined in Rule 12b-2 under the Act) of such person, shall become the “beneficial owner” (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, of securities of the Company representing 50 percent or more of the combined voting power of the Company’s then outstanding securities having the right to vote in an election of the Board (“Voting Securities”) (in such case other than as a result of an acquisition of securities directly from the Company); or
(ii)the date a majority of the members of the Board is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board before the date of the appointment or election; or
(iii)the consummation of (A) any consolidation or merger of the Company where the stockholders of the Company, immediately prior to the consolidation or merger, would not, immediately after the consolidation or merger, beneficially own (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, shares representing in the aggregate more than 50 percent of the voting shares of the Company issuing cash or securities in the consolidation or merger (or of its ultimate parent corporation, if any), or (B) any sale or other transfer (in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or substantially all of the assets of the Company and its affiliates on a consolidated basis. 
Notwithstanding the foregoing, a “Change in Control” shall not be deemed to have occurred for purposes of the foregoing clause (i) solely as the result of an acquisition of securities by the Company which, by reducing the number of shares of Voting Securities outstanding, increases the proportionate number of Voting Securities beneficially owned by any person to 50 percent or more of the combined voting power of all of the then outstanding Voting Securities; provided, however, that if any person referred to in this sentence shall thereafter become the beneficial owner of any additional shares of Voting Securities (other than pursuant to a stock split, stock dividend, or similar transaction or as a result of an acquisition of securities directly from the Company) and immediately thereafter beneficially owns 50 percent or more of the combined voting power of all of the then outstanding Voting Securities, then a “Change in Control” shall be deemed to have occurred for purposes of the foregoing clause (i).

6.Section 409A.
(a)Anything in this Agreement to the contrary notwithstanding, if at the time of the Employee’s separation from service within the meaning of Section 409A of the Code, the Company determines that the Employee is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that the Employee becomes entitled to under this Agreement on account of the Employee’s separation from service would be considered deferred compensation otherwise subject to the 20 percent additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable and such benefit shall not be provided until the date that is the earlier of (A) six months and one day after the Employee’s separation from service, or (B) the Employee’s death.  If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include a catch-up payment covering amounts that would otherwise have been paid during the six-month period but for the application of this provision, and the balance of the installments shall be payable in accordance with their original schedule.  
(b)All in-kind benefits provided and expenses eligible for reimbursement under this Agreement shall be provided by the Company or incurred by the Employee during the time periods set forth in this Agreement.  All reimbursements shall be paid as soon as administratively practicable, but in no event shall any reimbursement be paid after the last day of the taxable year following the taxable year in which the expense was incurred.  The amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect the in-kind benefits to be provided or the expenses eligible for reimbursement in any other taxable year (except for any lifetime or other aggregate limitation applicable to medical expenses).  Such right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit.
(c)To the extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon the Employee’s termination of employment, then such payments or benefits shall be payable only upon the Employee’s “separation from service.”  The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A-1(h).
(d)The parties intend that this Agreement will be administered in accordance with Section 409A of the Code.  To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with Section 409A of the Code.  Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2).  The parties agree that this Agreement may be amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party.

(e)The Company makes no representation or warranty and shall have no liability to the Employee or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section.
7.Confidential Information, Noncompetition and Cooperation. The terms of the Employee Non-Competition, Non-Solicitation, Confidentiality and Assignment Agreement (the “Restrictive Covenant Agreement”), between the Company and the Employee, attached hereto as Exhibit A, shall continue to be in full force and effect and are incorporated by reference in this Agreement.  The Employee hereby reaffirms the terms of the Restrictive Covenant Agreement as material terms of this Agreement.
(a)Litigation and Regulatory Cooperation.  During and after the Employee’s employment, the Employee shall cooperate fully with the Company in the defense or prosecution of any claims or actions now in existence or which may be brought in the future against or on behalf of the Company which relate to events or occurrences that transpired while the Employee was employed by the Company.  The Employee’s full cooperation in connection with such claims or actions shall include, but not be limited to, being available to meet with counsel to prepare for discovery or trial and to act as a witness on behalf of the Company at mutually convenient times.  During and after the Employee’s employment, the Employee also shall cooperate fully with the Company in connection with any investigation or review of any federal, state or local regulatory authority as any such investigation or review relates to events or occurrences that transpired while the Employee was employed by the Company.  The Company shall reimburse the Employee for any reasonable out-of-pocket expenses incurred in connection with the Employee’s performance of obligations pursuant to this Section 7(a).
(b)Relief.  The Employee agrees that it would be difficult to measure any damages caused to the Company which might result from any breach by the Employee of the promises set forth in this Section 7, and that in any event money damages would be an inadequate remedy for any such breach.  Accordingly, subject to Section 8 of this Agreement, the Employee agrees that if the Employee breaches, or proposes to breach, any portion of this Agreement, the Company shall be entitled, in addition to all other remedies that it may have, to an injunction or other appropriate equitable relief to restrain any such breach without showing or proving any actual damage to the Company. In addition, in the event the Employee breaches this Section 7 during a period when he is receiving severance payments pursuant to Section 4 or Section 5 hereof, the Company shall have the right to suspend or terminate such severance payments.  Such suspension or termination shall not limit the Company’s other options with respect to relief for such breach and shall not relieve the Employee of his duties under this Agreement.
(c)Protected Disclosures and Other Protected Action.  Nothing contained in this Agreement limits the Employee’s ability to communicate with any federal, state or local governmental agency or commission, including to provide documents or other information, without notice to the Company.
8.Arbitration of Disputes.  Any controversy or claim arising out of or relating to this Agreement or the breach thereof or otherwise arising out of the Employee’s employment or the 

9
ACTIVE/107570467.1  
​

​

termination of that employment (including, without limitation, any claims of unlawful employment discrimination whether based on age or otherwise) shall, to the fullest extent permitted by law, be settled by arbitration in any forum and form agreed upon by the parties or, in the absence of such an agreement, under the auspices of the American Arbitration Association (“AAA”) in Boston, Massachusetts in accordance with the Employment Dispute Resolution Rules of the AAA, including, but not limited to, the rules and procedures applicable to the selection of arbitrators.  In the event that any person or entity other than the Employee or the Company may be a party with regard to any such controversy or claim, such controversy or claim shall be submitted to arbitration subject to such other person or entity’s agreement.  Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction thereof.  This Section 8 shall be specifically enforceable.  Notwithstanding the foregoing, this Section 8 shall not preclude either party from pursuing a court action for the sole purpose of obtaining a temporary restraining order or a preliminary injunction in circumstances in which such relief is appropriate; provided that any other relief shall be pursued through an arbitration proceeding pursuant to this Section 8.
9.Consent to Jurisdiction.  To the extent that any court action is permitted consistent with or to enforce Section 8 of this Agreement, the parties hereby consent to the jurisdiction of the Superior Court of the Commonwealth of Massachusetts and the United States District Court for the District of Massachusetts.  Accordingly, with respect to any such court action, the Employee (a) submits to the personal jurisdiction of such courts; (b) consents to service of process; and (c) waives any other requirement (whether imposed by statute, rule of court, or otherwise) with respect to personal jurisdiction or service of process.
10.Integration.  This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements between the parties concerning such subject matter, including the Prior Agreement.
11.Withholding.  All payments made by the Company to the Employee under this Agreement shall be net of any tax or other amounts required to be withheld by the Company under applicable law.
12.Successor to the Employee.  This Agreement shall inure to the benefit of and be enforceable by the Employee’s personal representatives, executors, administrators, heirs, distributees, devisees and legatees.  In the event of the Employee’s death after his termination of employment but prior to the completion by the Company of all payments due to him under this Agreement, the Company shall continue such payments to the Employee’s beneficiary designated in writing to the Company prior to his death (or to his estate, if the Employee fails to make such designation).
13.Enforceability.  If any portion or provision of this Agreement (including, without limitation, any portion or provision of any section of this Agreement) shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable, shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law.

10

​

​

14.Survival.  The provisions of this Agreement shall survive the termination of this Agreement and/or the termination of the Employee’s employment to the extent necessary to effectuate the terms contained herein.
15.Waiver.  No waiver of any provision hereof shall be effective unless made in writing and signed by the waiving party.  The failure of any party to require the performance of any term or obligation of this Agreement, or the waiver by any party of any breach of this Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach.
16.Notices.  Any notices, requests, demands and other communications provided for by this Agreement shall be sufficient if in writing and delivered in person or sent by a nationally recognized overnight courier service or by registered or certified mail, postage prepaid, return receipt requested, to the Employee at the last address the Employee has filed in writing with the Company or, in the case of the Company, at its main offices, attention of the Board.
17.Amendment.  This Agreement may be amended or modified only by a written instrument signed by the Employee and by a duly authorized representative of the Company.
18.Governing Law.  This is a Massachusetts contract and shall be construed under and be governed in all respects by the laws of the Commonwealth of Massachusetts without giving effect to the conflict of laws principles thereof.
19.Counterparts.  This Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall be taken to be an original; but such counterparts shall together constitute one and the same document.
20.Successor to Company.  The Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Company expressly to assume and agree to perform this Agreement to the same extent that the Company would be required to perform it if no succession had taken place.  Failure of the Company to obtain an assumption of this Agreement at or prior to the effectiveness of any succession shall be a material breach of this Agreement.
21.Gender Neutral.  Wherever used herein, a pronoun in the masculine gender shall be considered as including the feminine gender unless the context clearly indicates otherwise.

Re:First Amendment to Employment Agreement
Dear Dr. Carven:
This letter agreement (the “Amendment”) by and between yourself and Scholar Rock, Inc. (the “Company”) is intended to amend that certain Employment Agreement between you and the Company, dated May 23, 2018 (the “Agreement”).  This Amendment is effective as of February 1, 2021.  Capitalized terms used, but not defined herein shall have the meanings given to such terms in the Agreement.
1.Section 1(b) of the Agreement is hereby amended and restated in its entirety to read as follows:
“Position and Duties.  Commencing February 1, 2021, the Employee shall serve as the Chief Scientific Officer of the Company, and shall have such duties and authorities as may from time to time be prescribed by the Chief Executive Officer of the Company (the “CEO”) or other executive designated by the CEO.  The Employee shall devote his full working time and efforts to the business and affairs of the Company.  Notwithstanding the foregoing, the Employee may serve on other boards of directors, with the approval of the CEO, or engage in religious, charitable or other community activities as long as such services and activities do not materially interfere with the Employee’s performance of his duties to the Company as provided in this Agreement.”
​
2.Section 2(a) of the Agreement is hereby amended and restated in its entirety to read as follows:
“Base Salary. Commencing January 1, 2021, the Employee’s annual base salary shall be $412,000.  The Employee’s base salary shall be reviewed annually by the Compensation Committee of the Board (the “Compensation Committee”) or the CEO.  The base salary in effect at any given time is referred to herein as “Base Salary.” The Base Salary shall be payable in a manner that is consistent with the Company’s usual payroll practices.”
​
3.The term “Agreement” shall be understood to refer to the Agreement and Amendment together, as appropriate. 
Other than the changes noted above, all other provisions of the Agreement shall remain in full force and effect according to their respective terms, and nothing contained herein shall be deemed a waiver of any right or abrogation of any obligation otherwise existing under the Agreement.

​

​

All issues and questions concerning the construction, validity, enforcement and interpretation of this Amendment shall be governed by, and construed in accordance with, the laws of the Commonwealth of Massachusetts, without giving effect to any choice of law or conflict of law rules or provisions (whether of the Commonwealth of Massachusetts or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the Commonwealth of Massachusetts.  In the event of any dispute, this Amendment is intended by the parties to be construed as a whole, to be interpreted in accordance with its fair meaning, and not to be construed strictly for or against either you or the Company or the “drafter” of all or any portion of this Amendment.  This Amendment may be executed in separate counterparts, each of which is deemed to be an original and all of which taken together constitute one and the same agreement.
