“2.1.3    Letter of Credit Sublimit Commitment.

(a)    Commitment. As part of the Revolving Line, subject to the terms and conditions hereof, the Issuing Lender agrees to issue letters of credit (“Letters of Credit”) for the account of the Borrower on any Business Day during the Letter of Credit Availability Period in such form as may reasonably be approved from time to time by the Issuing Lender; provided that the Issuing Lender shall have no obligation to issue (and shall not issue) any Letter of Credit if, after giving effect to such issuance, the L/C Exposure would exceed either the Dollar Equivalent of the Total L/C Commitments or the Availability Amount at such time. Each Letter of Credit shall (i) be denominated in Dollars or a Foreign Currency, and (ii) expire no later than the earlier of (x) the first anniversary of its date of issuance and (y) the Letter of Credit Maturity Date, provided that any Letter of Credit with a one-year term may provide for the renewal thereof for additional one-year periods (which shall in no event extend beyond the date referred to in clause (y) above).

(b)    Limitations on Issuance. The Issuing Lender shall not at any time be obligated to issue (and shall not issue) any Letter of Credit if: (i) such issuance would conflict with, or cause the Issuing Lender or any L/C Lender to exceed any limits imposed by, any applicable Requirement of Law; (ii) any order, judgment or decree of any Governmental Authority or arbitrator shall by its terms purport to enjoin or restrain the Issuing Lender from issuing, amending or reinstating such Letter of Credit, or any law, rule or regulation applicable to the Issuing Lender or any request, guideline or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over the Issuing Lender shall prohibit, or request that the Issuing Lender refrain from, the issuance, amendment, renewal or reinstatement of letters of credit generally or such Letter of Credit in particular or shall impose upon the Issuing Lender with respect to such Letter of Credit any restriction, reserve or capital requirement (for which the Issuing Lender is not otherwise compensated) not in effect on the Second Amendment Effective Date, or shall impose upon the Issuing Lender any loss, cost or expense which was not applicable on the Second Amendment Effective Date, which the Issuing Lender in good faith deems material to it and not subject to reimbursement by the Borrower in accordance with this Section 2.1.3; (iii) the Issuing Lender has received written notice from any Lender, the Administrative Agent or the Borrower, at least one (1) Business Day prior to the requested date of issuance, amendment, renewal or reinstatement of such Letter of Credit, that one

(c)    Procedures for Issuance of Letters of Credit. The Borrower may from time to time request that the Issuing Lender issue a Letter of Credit for the account of the Borrower by delivering to the Issuing Lender at its address for notices specified herein an Application therefor, completed to the satisfaction of the Issuing Lender, and such other certificates, documents and other papers and information as the Issuing Lender may request. Upon receipt of any Application, the Issuing Lender will process such Application and the certificates, documents and other papers and information delivered to it in connection therewith in accordance with its customary procedures and shall promptly issue the Letter of Credit requested thereby (but in no event shall the Issuing Lender be required to issue any Letter of Credit earlier than three (3) Business Days after its receipt of the Application therefor and all such other certificates, documents and other papers and information relating thereto) by issuing the original of such Letter of Credit to the beneficiary thereof or as otherwise may be agreed to by the Issuing Lender and the Borrower. The Issuing Lender shall furnish a copy of such Letter of Credit to the Borrower promptly following the issuance thereof. The Issuing Lender shall promptly furnish to the Administrative Agent, which shall in turn promptly furnish to the Lenders, notice of the issuance of each Letter of Credit (including the amount thereof).

(d)    Fees and Other Charges.

(i)    The Borrower agrees to pay, with respect to each outstanding Letter of Credit issued for the account of (or at the request of) the Borrower, (X) a fronting fee of 0.125% per annum on the daily amount available to be drawn under each such Letter of Credit to the Issuing Lender for its own account (a “Letter of Credit Fronting Fee”), and (Y) a letter of credit fee of 2.00% per annum multiplied by the daily

3

amount available to be drawn under each such Letter of Credit on the drawable amount of such Letter of Credit to the Administrative Agent for the ratable account of the L/C Lenders (determined in accordance with their respective L/C Percentages) (a “Letter of Credit Fee”), in each case payable quarterly in arrears on the last Business Day of March, June, September and December of each year and on the Letter of Credit Maturity Date (each, an “L/C Fee Payment Date”) after the issuance date of such Letter of Credit, and (Z) the Issuing Lender’s standard and reasonable fees with respect to the issuance, amendment, renewal or extension of any Letter of Credit issued for the account of (or at the request of) the Borrower or processing of drawings thereunder (the fees in this clause (Z), collectively, the “Issuing Lender Fees”). All Letter of Credit Fronting Fees and Letter of Credit Fees shall be computed on the basis of the actual number of days elapsed in a year of 360 days.

(ii)    In addition to the foregoing fees, the Borrower shall pay or reimburse the Issuing Lender for such normal and customary costs and expenses as are incurred or charged by the Issuing Lender in issuing, negotiating, effecting payment under, amending or otherwise administering any Letter of Credit.

(iii)    The Borrower shall furnish to the Issuing Lender and the Administrative Agent such other documents and information pertaining to any requested Letter of Credit issuance, amendment or renewal, including any L/C-Related Documents, as the Issuing Lender or the Administrative Agent may reasonably require. This Agreement shall control in the event of any conflict with any L/C-Related Document (other than any Letter of Credit).

(iv)    Any letter of credit fees otherwise payable for the account of a Defaulting Lender with respect to any Letter of Credit as to which such Defaulting Lender has not provided Cash Collateral satisfactory to the Issuing Lender pursuant to Section 2.1.3(l) shall be payable, to the maximum extent permitted by applicable law, to the other L/C Lenders in accordance with the upward adjustments in their respective L/C Percentages allocable to such Letter of Credit, with the balance of such fee, if any, payable to the Issuing Lender for its own account.

(v)    All fees payable under this Section 2.1.3(d) shall be fully earned on the date paid and nonrefundable.

(vi)    To guard against fluctuations in currency exchange rates, upon the issuance of any Letter of Credit payable in a Foreign Currency, Issuing Lender shall create a reserve (the “Letter of Credit Reserve”) under the Revolving Line in an amount equal to a percentage (which percentage shall be determined by Issuing Lender in its reasonable discretion) of the face amount of such Letter of Credit. The amount of the Letter of Credit Reserve may be adjusted by Issuing Lender from time to time to account for fluctuations in the exchange rate. The availability of funds under the Revolving Line shall be reduced by the amount of such Letter of Credit Reserve for as long as such Letter of Credit remains outstanding.

4

(e)    L/C Participations.    The Issuing Lender irrevocably agrees to grant and hereby grants to each L/C Lender, and, to induce the Issuing Lender to issue Letters of Credit, each L/C Lender irrevocably agrees to accept and purchase and hereby accepts and purchases from the Issuing Lender, on the terms and conditions set forth below, for such L/C Lender’s own account and risk an undivided interest equal to such L/C Lender’s L/C Percentage in the Issuing Lender’s obligations and rights under and in respect of each Letter of Credit and the amount of each draft paid by the Issuing Lender thereunder. Each L/C Lender agrees with the Issuing Lender that, if a draft is paid under any Letter of Credit for which the Issuing Lender is not reimbursed in full by the Borrower pursuant to Section 2.1.3(g), such L/C Lender shall pay to the Issuing Lender upon demand at the Issuing Lender’s address for notices specified herein an amount equal to such L/C Lender’s L/C Percentage of the amount of such draft (or the Dollar Equivalent thereof with respect to any Letters of Credit payable in a Foreign Currency), or any part thereof, that is not so reimbursed. Each L/C Lender’s obligation to pay such amount shall be absolute and unconditional and shall not be affected by any circumstance, including (i) any setoff, counterclaim, recoupment, defense or other right that such L/C Lender may have against the Issuing Lender, the Borrower or any other Person for any reason whatsoever, (ii) the occurrence of an Event of Default or the failure to satisfy any of the other conditions specified in Section 3.2, (iii) any adverse change in the condition (financial or otherwise) of the Borrower, (iv) any breach of this Agreement or any other Loan Document by the Borrower or any other L/C Lender, or (v) any other circumstance, happening or event whatsoever, whether or not similar to any of the foregoing.

(f)    Existing Letters of Credit. The Existing Letters of Credit shall in no case be deemed to be a Letter of Credit outstanding under this Agreement and shall not be entitled to the benefits of this Agreement or any other Loan Document.

(g)    Reimbursement.

(i)    If the Issuing Lender shall make any L/C Disbursement in respect of a Letter of Credit, the Issuing Lender shall notify the Borrower and the Administrative Agent thereof and the Borrower shall pay or cause to be paid to the Issuing Lender an amount equal to the entire amount of such L/C Disbursement not later than the immediately following Business Day. Each such payment shall be made to the Issuing Lender at its address for notices referred to herein, in Dollars and in immediately available funds.

(ii)    If the Issuing Lender shall not have received from the Borrower the payment that it is required to make pursuant to (g)(i) above, with respect to a Letter of Credit within the time specified in such clause, the Issuing Lender will promptly notify the Administrative Agent of the L/C

5

Disbursement and the Administrative Agent will promptly notify each L/C Lender of such L/C Disbursement and its L/C Percentage thereof, and each L/C Lender shall pay to the Issuing Lender upon demand at the Issuing Lender’s address for notices specified herein an amount equal to such L/C Lender’s L/C Percentage of such L/C Disbursement, or the Dollar Equivalent thereof with respect to any Letters of Credit payable in a Foreign Currency (and the Administrative Agent may apply Cash Collateral provided for this purpose); upon such payment pursuant to this paragraph to reimburse the Issuing Lender for any L/C Disbursement, the Borrower shall be required to reimburse the L/C Lenders for such payments (including interest accrued thereon from the date of such payment until the date of such reimbursement at the rate applicable to Overadvances) on demand; provided that if at the time of and after giving effect to such payment by the L/C Lenders, the conditions to borrowings set forth in Section 3.2 are satisfied, the Borrower may, by written notice to the Administrative Agent certifying that such conditions are satisfied and that all interest owing under this paragraph has been paid, request that such payments by the L/C Lenders be converted into an Advance under the Revolving Line (a “Revolving Loan Conversion”), in which case, if such conditions are in fact satisfied, the L/C Lenders shall be deemed to have extended, and the Borrower shall be deemed to have accepted, an Advance in the aggregate principal amount of such payment without further action on the part of any party, and the Total L/C Commitments shall be permanently reduced by such amount; any amount so paid pursuant to this paragraph shall, on and after the payment date thereof, be deemed to be Advances for all purposes hereunder; provided that the Issuing Lender, at its option, may effectuate a Revolving Loan Conversion regardless of whether the conditions to borrowings set forth in Section 3.2 are satisfied.

(iii)    Promptly following receipt by the Administrative Agent (or the Issuing Lender, as the case may be) of a payment from the Borrower with respect to an L/C Disbursement, the Administrative Agent (or the Issuing Lender) shall, to the extent that the L/C Lenders have made payments pursuant to this paragraph to reimburse the Issuing Lender, repay such L/C Lenders on a pro rata basis.

(h)    Obligations Absolute. The Borrower’s obligations under this Section 2.1.3 shall be absolute and unconditional under any and all circumstances and irrespective of any setoff, counterclaim or defense to payment that the Borrower may have or have had against the Issuing Lender or any L/C Lender, any beneficiary of a Letter of Credit or any other Person. The Borrower also agrees with the Issuing Lender that the Issuing Lender or any L/C Lender shall not be responsible for, and the Borrower’s obligations hereunder shall not be affected by, among other things, the validity or genuineness of documents or of any endorsements thereon, even though such documents shall in fact prove to be

6

invalid, fraudulent or forged, or any dispute between or among the Borrower and any beneficiary of any Letter of Credit or any other party to which such Letter of Credit may be transferred or any claims whatsoever of the Borrower against any beneficiary of such Letter of Credit or any such transferee. The Issuing Lender and any L/C Lender shall not be liable for any error, omission, interruption or delay in transmission, dispatch or delivery of any message or advice, however transmitted, in connection with any Letter of Credit, except for errors or omissions found by a final and nonappealable decision of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Issuing Lender or any L/C Lender. The Borrower agrees that any action taken or omitted by the Issuing Lender or any L/C Lender under or in connection with any Letter of Credit or the related drafts or documents, if done in the absence of gross negligence or willful misconduct, shall be binding on the Borrower and shall not result in any liability of the Issuing Lender or any L/C Lender to the Borrower. In addition to amounts payable as elsewhere provided in the Agreement, the Borrower hereby agrees to pay and to protect, indemnify, and save Issuing Lender and any L/C Lender harmless from and against any and all claims, demands, liabilities, damages, losses, costs, charges and expenses (including reasonable attorneys’ fees and allocated costs of internal counsel) that the Issuing Lender or any L/C Lender may incur or be subject to as a consequence, direct or indirect, of (i) the issuance of any Letter of Credit, or (ii) the failure of Issuing Lender or of any L/C Lender to honor a demand for payment under any Letter of Credit thereof as a result of any act or omission, whether rightful or wrongful, of any present or future de jure or de facto government or Governmental Authority, in each case other than to the extent solely as a result of the gross negligence or willful misconduct of Issuing Lender or such L/C Lender (as finally determined by a court of competent jurisdiction).

(i)    Letter of Credit Payments. If any draft shall be presented for payment under any Letter of Credit, the Issuing Lender shall promptly notify the Borrower and the Administrative Agent of the date and amount thereof. The responsibility of the Issuing Lender to the Borrower in connection with any draft presented for payment under any Letter of Credit shall, in addition to any payment obligation expressly provided for in such Letter of Credit, be limited to determining that the documents (including each draft) delivered under such Letter of Credit in connection with such presentment are substantially in conformity with such Letter of Credit.

(j)    Applications. To the extent that any provision of any Application related to any Letter of Credit is inconsistent with the provisions of this Section 2.1.3, the provisions of this Section 2.1.3 shall apply.

(k)    Interim Interest. If the Issuing Lender shall make any L/C Disbursement in respect of a Letter of Credit, then, unless either the Borrower shall have reimbursed such L/C Disbursement in full within the time period specified in Section 2.1.3(g) or the L/C Lenders shall have reimbursed such L/C Disbursement

7

in full on such date as provided in Section 2.1.3(g), in each case the unpaid amount thereof shall bear interest for the account of the Issuing Lender, for each day from and including the date of such L/C Disbursement to but excluding the date of payment by the Borrower, at the rate per annum that would apply to an Overadvance.

(l)    Cash Collateral.

(i)    Certain Credit Support Events. Upon the request of the Administrative Agent or the Issuing Lender (X) if the Issuing Lender has honored any full or partial drawing request under any Letter of Credit and such drawing has resulted in an L/C Advance by all the L/C Lenders that is not reimbursed by the Borrower or converted into an Advance under the Revolving Line pursuant to Section 2.1.3(g)(ii), or (Y) if, as of the Letter of Credit Maturity Date, any L/C Exposure for any reason remains outstanding, the Borrower shall, in each case, immediately Cash Collateralize the then effective L/C Exposure in an amount equal to 105% of such L/C Exposure.

At any time that there shall exist a Defaulting Lender, within one (1) Business Day following the request of the Administrative Agent or the Issuing Lender (with a copy to the Administrative Agent), the Borrower shall deliver to the Administrative Agent Cash Collateral in an amount sufficient to cover 105% of the Fronting Exposure relating to the Letters of Credit (after giving effect to any Cash Collateral provided by such Defaulting Lender).

(ii)    Grant of Security Interest. All Cash Collateral (other than credit support not constituting funds subject to deposit) shall be maintained in blocked, non-interest bearing deposit accounts with the Administrative Agent. The Borrower, and to the extent provided by any Lender or Defaulting Lender, such Lender or Defaulting Lender, hereby grants to (and subjects to the control of) the Administrative Agent, for the benefit of the Administrative Agent, the Issuing Lender and the L/C Lenders, and agrees to maintain, a first priority security interest and Lien in all such Cash Collateral and in all proceeds thereof, as security for the Obligations to which such Cash Collateral may be applied pursuant to Section 2.1.3(l)(iii) below. If at any time the Administrative Agent determines that Cash Collateral is subject to any right or claim of any Person other than the Administrative Agent or any Issuing Lender as herein provided, or that the total amount of such Cash Collateral is less than 105% of the applicable L/C Exposure, Fronting Exposure and other Obligations secured thereby, the Borrower or the relevant Lender or Defaulting Lender, as applicable, will, promptly upon demand by the Administrative Agent, pay or provide to the Administrative Agent additional Cash Collateral in an amount sufficient to eliminate such deficiency (after giving effect to any Cash Collateral provided by such Defaulting Lender).

8

(iii)    Application. Notwithstanding anything to the contrary contained in this Agreement, Cash Collateral provided under this section or otherwise in respect of Letters of Credit shall be held and applied to the satisfaction of the specific L/C Exposure, obligations to fund participations therein (including, as to Cash Collateral provided by a Defaulting Lender, any interest accrued on such obligation) and other obligations for which the Cash Collateral was so provided, prior to any other application of such property as may otherwise be provided for herein.

(iv)    Termination of Requirement. Cash Collateral (or the appropriate portion thereof) provided to reduce Fronting Exposure in respect of Letters of Credit or other Obligations shall no longer be required to be held as Cash Collateral pursuant to this Section 2.1.3(l) following (X) the elimination of the applicable Fronting Exposure and other Obligations giving rise thereto (including by the termination of the Defaulting Lender status of the applicable Lender), or (Y) a determination by the Administrative Agent and the Issuing Lender that there exists excess Cash Collateral; provided, however, (I) that Cash Collateral furnished by or on behalf of a Borrower shall not be released during the continuance of an Event of Default, and (II) that the Person providing such Cash Collateral and the Issuing Lender may agree that such Cash Collateral shall not be released but instead shall be held to support future anticipated Fronting Exposure or other obligations; and provided further, that to the extent that such Cash Collateral was provided by the Borrower, such Cash Collateral shall remain subject to any security interest and Lien granted pursuant to the Loan Documents.

(m)    Additional Issuing Lenders. The Borrower may, at any time and from time to time with the consent of the Administrative Agent (which consent shall not be unreasonably withheld) and such Lender, designate one or more additional Lenders to act as an issuing bank under the terms of this Agreement. Any Lender designated as an issuing bank pursuant to this paragraph shall be deemed to be an “Issuing Lender” (in addition to being a Lender) in respect of Letters of Credit issued or to be issued by such Lender, and, with respect to such Letters of Credit, such term shall thereafter apply to the other Issuing Lender and such Lender.

(n)    Resignation of the Issuing Lender. The Issuing Lender may resign at any time by giving at least 30 days’ prior written notice to the Administrative Agent, the Lenders and the Borrower. Subject to the next succeeding paragraph, upon the acceptance of any appointment as the Issuing Lender hereunder by a Lender that shall agree to serve as successor Issuing Lender, such successor shall succeed to and become vested with all the interests, rights and obligations of the retiring Issuing Lender and the retiring Issuing Lender shall be discharged from its obligations to issue additional Letters of Credit hereunder without affecting its rights and obligations with respect to Letters of Credit previously issued by it. At the time such resignation shall become effective, the Borrower shall pay all

9

accrued and unpaid fees pursuant to Section 2.1.3(c). The acceptance of any appointment as the Issuing Lender hereunder by a successor Lender shall be evidenced by an agreement entered into by such successor, in a form satisfactory to the Borrower and the Administrative Agent, and, from and after the effective date of such agreement, (i) such successor Lender shall have all the rights and obligations of the previous Issuing Lender under this Agreement and the other Loan Documents and (ii) references herein and in the other Loan Documents to the term “Issuing Lender” shall be deemed to refer to such successor or to any previous Issuing Lender, or to such successor and all previous Issuing Lenders, as the context shall require. After the resignation of the Issuing Lender hereunder, the retiring Issuing Lender shall remain a party hereto and shall continue to have all the rights and obligations of an Issuing Lender under this Agreement and the other Loan Documents with respect to Letters of Credit issued by it prior to such resignation, but shall not be required to issue additional Letters of Credit or to extend, renew or increase any existing Letter of Credit.

(o)    Applicability of UCP and ISP. Unless otherwise expressly agreed by the Issuing Lender and the Borrower when a Letter of Credit is issued and subject to applicable laws, the Letters of Credit shall be governed by and subject to (i) with respect to standby Letters of Credit, the rules of the ISP, and (b) with respect to commercial Letters of Credit, the rules of the Uniform Customs and Practice for Documentary Credits, as published in its most recent version by the International Chamber of Commerce on the date any commercial Letter of Credit is issued.”

2.2    Section 2.1.4 (Term Loan 2017). The Loan Agreement shall be amended by inserting the following new Section 2.1.4 immediately following Section 2.1.3 thereof:

“2.1.4 Term Loan 2017.

(a)    Availability. Subject to the terms and conditions of this Agreement, the Lenders, severally and not jointly, shall make one (1) term loan (the “Term Loan 2017”) to Borrower on the Second Amendment Effective Date in an aggregate principal amount of Thirty Million Dollars ($30,000,000.00); provided that a portion of the proceeds of the Term Loan 2017 shall be used to repay in full Borrower’s outstanding Existing Term Loan Obligations. Borrower hereby authorizes Agent to apply such portion of the proceeds to the Existing Term Loan Obligations as part of the funding process without actually depositing such funds in an account of Borrower.

(b)    Interest. Commencing on the first (1^st) Payment Date of the month following the month in which the Funding Date of the Term Loan 2017 occurs, and continuing on each Payment Date thereafter, Borrower shall make monthly payments of interest on the outstanding principal amount of the Term Loan 2017 at the rate set forth in Section 2.3(a).

10

(c)    Repayment. Commencing on December 1, 2018 and continuing on each Payment Date thereafter, Borrower shall repay the Term Loan 2017 in (i) twenty-four (24) equal monthly installments of principal, based on a forty-eight (48) month amortization schedule; plus (ii) monthly payments of accrued interest at the rate set forth in Section 2.3(a). All outstanding principal and accrued and unpaid interest with respect to the Term Loan 2017, and all other outstanding Obligations with respect to the Term Loan 2017, are due and payable in full on the Term Loan 2017 Maturity Date. Once repaid, no portion of the Term Loan 2017 may be reborrowed.

(d)    Voluntary Prepayment. Borrower shall have the option to prepay all or any portion of the Term Loan 2017, provided Borrower (i) provides written notice to Agent of its election to prepay the Term Loan 2017 at least three (3) days prior to such prepayment and (ii) pays, on the date of such prepayment, (a) the principal amount of the Term Loan 2017 to be repaid and accrued but unpaid interest, plus (b) the applicable Term Loan 2017 Prepayment Premium, plus (c) all other sums, including Lender Expenses, if any, that shall have become due and payable. Voluntary prepayments hereunder shall be in a minimum principal amount of Five Million Dollars ($5,000,000.00) and increments of One Million Dollars ($1,000,000.00) in excess thereof (or if less, the then-remaining outstanding principal balance of the Term Loan 2017). Notwithstanding the foregoing, Borrower may rescind any notice of prepayment by notice to the Agent on or before the date of prepayment if such prepayment would have resulted from a refinancing or occurrence of another event, which refinancing or event shall not be consummated or shall otherwise be delayed.

(d)    Mandatory Prepayment upon an Acceleration. If the Term Loan 2017 is accelerated following the occurrence of an Event of Default (including, without limitation, an Event of Default pursuant to Section 8.5 hereof), Borrower shall immediately pay to Agent, for the ratable benefit of the Term Loan 2017 Lenders, an amount equal to the sum of (i) all outstanding principal of the Term Loan 2017 and accrued but unpaid interest thereon, plus (ii) the applicable Term Loan 2017 Prepayment Premium on the full outstanding principal balance of the Term Loan 2017, plus (iii) all other sums, including Lender Expenses, if any, that shall have become due and payable.”

Without limiting Borrower’s obligation to repay Agent and the Lenders any Overadvance, Borrower agrees to pay Agent, for the ratable benefit of the Lenders, interest on the outstanding amount of any Overadvance, on demand, at the Default Rate.”
