As used herein, the following terms are defined in accordance with the UCC in effect in the State of Texas from time to time: “As-Extracted Collateral,” “Chattel Paper,” “Commercial Tort Claim,” “Commodity Account,” “Deposit Account,” “Document,” “Equipment,” “Fixtures,” “General Intangibles,” “Goods,” “Instrument,” “Investment Property,” “Letter-of-Credit Right” “Securities Account” and “Supporting Obligation.” 1.4. Certain Matters of Construction. The terms “herein,” “hereof,” “hereunder” and other words of similar import refer to this Agreement as a whole and not to any particular section, paragraph or subdivision. Any pronoun used shall be deemed to cover all genders. In the computation of periods of time from a specified date to a later specified date, “from” means

-40- “from and including,” and “to” and “until” each mean “to but excluding.” The terms “including” and “include” shall mean “including, without limitation” and, for purposes of each Loan Document, the parties agree that the rule of ejusdem generis shall not be applicable to limit any provision. Section titles appear as a matter of convenience only and shall not affect the interpretation of any Loan Document.

Borrowing Base calculations shall be consistent with historical methods of valuation and calculation, and otherwise satisfactory to Agent (and not necessarily calculated in accordance with GAAP). Borrowers shall have the burden of establishing any alleged negligence, misconduct or lack of good faith by Agent, Issuing Bank or any Lender under any Loan Documents. No provision of any Loan Documents shall be construed against any party by reason of such party having, or being deemed to have, drafted the provision. A reference to Borrowers’ “knowledge” or similar concept means actual knowledge of a Senior Officer, or knowledge that a Senior Officer would have obtained if he or she had engaged in good faith and diligent performance of his or her duties, including reasonably specific inquiries of employees or agents and a good faith attempt to ascertain the matter. SECTION 2. CREDIT FACILITIES 2.1. Revolver Commitment. 2.1.1. Revolver Loans. On the Closing Date, the “Revolver Loans” (as defined in the Initial Loan Agreement) held by the Lenders shall be deemed to be Revolver Loans under this Agreement. Each Lender hereby agrees, subject to its Revolver Commitment, on the terms set forth herein, to make Revolver Loans to Borrowers from time to time through the Commitment Termination Date. The Revolver Loans may be repaid and reborrowed as provided herein. In no event shall Lenders have any obligation to honor a request for a Revolver Loan if the unpaid balance of Revolver Loans outstanding at such time (including the requested Loan) would exceed the Borrowing Base. 2.1.2. Revolver Notes. The Revolver Loans made by each Lender and interest accruing thereon shall be evidenced by the records of Agent and such Lender. At the request of any Lender, Borrowers shall deliver to such Lender a promissory note evidencing its Revolver Loans. 2.1.3. Use of Proceeds. The proceeds of Revolver Loans shall be used by Borrowers solely (a) to pay fees and transaction expenses associated with the closing of this

-41- credit facility; (b) to pay Obligations in accordance with this Agreement; and (c) for lawful corporate purposes of Borrowers, including working capital. 2.1.4. Voluntary Reduction or Termination of Revolver Commitments. (a) The Revolver Commitments shall terminate on the Revolver Termination Date, unless sooner terminated in accordance with this Agreement. Upon at least 5 Business Days’ prior written notice to Agent, Borrowers may, at their option, terminate the Revolver Commitments and this credit facility. Any notice of termination given by Borrowers shall be irrevocable. On the termination date, Borrowers shall make Full Payment of all Obligations. (b) Borrowers may permanently reduce the Revolver Commitments, on a Pro Rata basis for each Lender, upon at least 5 Business Days’ prior written notice to Agent, which notice shall specify the amount of the reduction and shall be irrevocable once given. Each reduction (in the aggregate for all Lenders) shall be in a minimum amount of $5,000,000, or an increment of $1,000,000 in excess thereof. 2.1.5. Overadvances. If the aggregate Revolver Loans exceed the Borrowing Base (“Overadvance”) at any time, the excess amount shall be payable by Borrowers on demand by Agent, but all such Revolver Loans shall nevertheless constitute Obligations secured by the Collateral and entitled to all benefits of the Loan Documents. Agent may require Lenders to honor requests for Overadvance Loans and to forbear from requiring Borrowers to cure an Overadvance, either if (a) no other Event of Default is known to Agent, as long as (i) the Overadvance does not continue for more than 30 consecutive days and (ii) the Overadvance is not known by Agent to exceed $25,000,000, or (b) regardless of whether an Event of Default exists, Agent discovers an Overadvance not previously known by it to exist, as long as from the date of such discovery the Overadvance (i) is not increased by more than $2,500,000, and (ii) does not continue for more than 30 consecutive days. In no event shall Overadvance Loans be required that would cause the outstanding Revolver Loans and LC Obligations to exceed the aggregate Revolver Commitments. Any funding of an Overadvance Loan or sufferance of an Overadvance shall not constitute a waiver by Agent or Lenders of the Event of Default caused thereby. In no event shall any Borrower or other Obligor be deemed a beneficiary of this Section nor authorized to enforce any of its terms. 2.1.6. Protective Advances. Agent shall be authorized, in its discretion, at any time that any conditions in Section 6 are not satisfied to make Base Rate Revolver Loans (“Protective Advances”) (a) up to an aggregate amount of $25,000,000 outstanding at any time, if Agent deems such Loans necessary or desirable to preserve or protect Collateral, or to enhance the collectibility or repayment of Obligations, as long as such Loans do not cause the outstanding Revolver Loans and LC Obligations to exceed the aggregate Revolver Commitments; or (b) to pay any other amounts chargeable to Obligors under any Loan Documents, including interest, costs, fees and expenses. Each Lender shall participate in each Protective Advance on a Pro Rata basis. Required Lenders may at any time revoke Agent’s authority to make further Protective Advances under clause (a) by written notice to Agent. Absent such revocation, Agent’s determination that funding of a Protective Advance is appropriate shall be conclusive. 2.1.7. Increase in Revolver Commitments. Borrowers may request an increase in Revolver Commitments from time to time upon notice to Agent (a “Revolver Commitments Increase Event”), as long as (i) the requested increase is in a minimum amount of $10,000,000

-42- and is offered on the same terms as existing Revolver Commitments, except for a closing fee specified by Agent, (ii) increases under this Section 2.1.7 after the Closing Date do not exceed $100,000,000 in the aggregate and no more than three increases are made, (iii) no reduction in Revolver Commitments pursuant to Section 2.1.4 has occurred prior to the requested increase, and (iv) the requested increase does not cause (1) this Agreement to cease being an “ABL Agreement” pursuant to the Intercreditor Agreement (if then in effect) or enjoy similar rights and benefits under any intercreditor agreement (if any) relating to any Refinancing Debt refinancing or refunding the Senior Notes, or (2) the Revolver Commitments to cease being “Permitted Indebtedness” under the Senior Notes Agreement or under any comparable agreement relating to any Refinancing Debt refinancing or refunding the Senior Notes. Agent shall promptly notify the Lenders of the requested increase and, within ten (10) Business Days thereafter, each Lender shall notify Agent if and to what extent such Lender commits to increase its Revolver Commitment. Any Lender not responding within such period shall be deemed to have declined an increase. If Lenders fail to commit to the full requested increase, Eligible Assignees may issue additional Revolver Commitments and become Lenders hereunder. Agent may allocate, in consultation with Borrower Agent, the increased Revolver Commitments among committing Lenders and, if necessary, Eligible Assignees. Provided the conditions set forth in Section 6.2 are satisfied, total Revolver Commitments shall be increased by the requested amount (or such lesser amount committed by Lenders and Eligible Assignees) on a date agreed upon by Agent and Borrower Agent, but no later than 45 days following Borrowers’ increase request. Agent, Obligors, and new and existing Lenders shall execute and deliver such documents and agreements as Agent deems appropriate to evidence the increase in and allocations of Revolver Commitments. On the effective date of an increase, all outstanding Revolver Loans, LC Obligations and other exposures under the Revolver Commitments shall be reallocated among Lenders, and settled by Agent if necessary, in accordance with Lenders’ adjusted shares of such Revolver Commitments. In no event shall the provisions of this Section 2.1.7 or any other provision of this Agreement or any other Loan Document be deemed to create any obligation on the part of any Lender to agree to any increase in the Revolver Commitments and Borrowers agree that any such increase shall be at the sole option of each Lender. 2.2. Letter of Credit Facility. 2.2.1. Issuance of Letters of Credit. Borrowers acknowledge and agree that, as of the Closing Date, the “Letters of Credit” listed on Schedule 2.2.1 have been issued and are outstanding under the Initial Loan Agreement. On the Closing Date, such “Letters of Credit” automatically, and without any action on the part of any Person, shall be deemed to be Letters of Credit issued hereunder for all purposes. Issuing Bank shall issue Letters of Credit from time to time until 30 days prior to the Revolver Termination Date (or until the Commitment Termination Date, if earlier), on the terms set forth herein, including the following: (a) Each Borrower acknowledges that Issuing Bank’s issuance of any Letter of Credit is conditioned upon Issuing Bank’s receipt of a LC Application with respect to the requested Letter of Credit, as well as such other instruments and agreements as Issuing Bank may customarily require for issuance of a letter of credit of similar type and amount. Issuing Bank shall have no obligation to issue any Letter of Credit unless (i) Issuing Bank receives a LC Request and LC Application at least three Business Days prior to the requested date of issuance; (ii) each LC Condition is satisfied; and (iii) if a Defaulting Lender exists, such Lender or Borrowers have entered into arrangements satisfactory to Agent and Issuing Bank to eliminate any Fronting Exposure associated with such Lender. If, in sufficient time to act, Issuing Bank

-43- receives written notice from Required Lenders that a LC Condition has not been satisfied, Issuing Bank shall not issue the requested Letter of Credit. Prior to receipt of any such notice, Issuing Bank shall not be deemed to have knowledge of any failure of LC Conditions. (b) Letters of Credit may be requested by a Borrower to support obligations incurred in the Ordinary Course of Business, or as otherwise approved by Agent. The renewal or extension of any Letter of Credit shall be treated as the issuance of a new Letter of Credit, except that delivery of a new LC Application shall be required at the discretion of Issuing Bank. (c) Borrowers assume all risks of the acts, omissions or misuses of any Letter of Credit by the beneficiary. In connection with issuance of any Letter of Credit, none of Agent, Issuing Bank or any Lender shall be responsible for the existence, character, quality, quantity, condition, packing, value or delivery of any goods purported to be represented by any Documents; any differences or variation in the character, quality, quantity, condition, packing, value or delivery of any goods from that expressed in any Documents; the form, validity, sufficiency, accuracy, genuineness or legal effect of any Documents or of any endorsements thereon; the time, place, manner or order in which shipment of goods is made; partial or incomplete shipment of, or failure to ship, any goods referred to in a Letter of Credit or Documents; any deviation from instructions, delay, default or fraud by any shipper or other Person in connection with any goods, shipment or delivery; any breach of contract between a shipper or vendor and a Borrower; errors, omissions, interruptions or delays in transmission or delivery of any messages, by mail, cable, telegraph, telex, telecopy, e-mail, telephone or otherwise; errors in interpretation of technical terms; the misapplication by a beneficiary of any Letter of Credit or the proceeds thereof; or any consequences arising from causes beyond the control of Issuing Bank, Agent or any Lender, including any act or omission of a Governmental Authority. The rights and remedies of Issuing Bank under the Loan Documents shall be cumulative. Issuing Bank shall be fully subrogated to the rights and remedies of each beneficiary whose claims against Borrowers are discharged with proceeds of any Letter of Credit. (d) In connection with its administration of and enforcement of rights or remedies under any Letters of Credit or LC Documents, Issuing Bank shall be entitled to act, and shall be fully protected in acting, upon any certification, documentation or communication in whatever form believed by Issuing Bank, in good faith, to be genuine and correct and to have been signed, sent or made by a proper Person. Issuing Bank may consult with and employ legal counsel, accountants and other experts to advise it concerning its obligations, rights and remedies, and shall be entitled to act upon, and shall be fully protected in any action taken in good faith reliance upon, any advice given by such experts. Issuing Bank may employ agents and attorneys-in-fact in connection with any matter relating to Letters of Credit or LC Documents, and shall not be liable for the gross negligence or willful misconduct of agents and attorneys-in-fact selected with reasonable care. 2.2.2. Reimbursement; Participations. (a) If Issuing Bank honors any request for payment under a Letter of Credit, Borrowers shall pay to Issuing Bank, on the same day (“Reimbursement Date”), the amount paid by Issuing Bank under such Letter of Credit, together with interest at the interest rate for Base Rate Revolver Loans from the Reimbursement Date until payment by Borrowers.

-44- The obligation of Borrowers to reimburse Issuing Bank for any payment made under a Letter of Credit shall be absolute, unconditional, irrevocable, and joint and several, and shall be paid without regard to any lack of validity or enforceability of any Letter of Credit or the existence of any claim, setoff, defense or other right that Borrowers may have at any time against the beneficiary. Whether or not Borrower Agent submits a Notice of Borrowing, Borrowers shall be deemed to have requested a Borrowing of Base Rate Revolver Loans in an amount necessary to pay all amounts due Issuing Bank on any Reimbursement Date and each Lender agrees to fund its Pro Rata share of such Borrowing whether or not the Commitments have terminated, an Overadvance exists or is created thereby, or the conditions in Section 6 are satisfied. (b) Upon issuance of a Letter of Credit, each Lender shall be deemed to have irrevocably and unconditionally purchased from Issuing Bank, without recourse or warranty, an undivided Pro Rata interest and participation in all LC Obligations relating to the Letter of Credit. If Issuing Bank makes any payment under a Letter of Credit and Borrowers do not reimburse such payment on the Reimbursement Date, Agent shall promptly notify Lenders and each Lender shall promptly (within one Business Day) and unconditionally pay to Agent, for the benefit of Issuing Bank, the Lender’s Pro Rata share of such payment. Upon request by a Lender, Issuing Bank shall furnish copies of any Letters of Credit and LC Documents in its possession at such time. (c) The obligation of each Lender to make payments to Agent for the account of Issuing Bank in connection with Issuing Bank’s payment under a Letter of Credit shall be absolute, unconditional and irrevocable, not subject to any counterclaim, setoff, qualification or exception whatsoever, and shall be made in accordance with this Agreement under all circumstances, irrespective of any lack of validity or unenforceability of any Loan Documents; any draft, certificate or other document presented under a Letter of Credit having been determined to be forged, fraudulent, invalid or insufficient in any respect or any statement therein being untrue or inaccurate in any respect; or the existence of any setoff or defense that any Obligor may have with respect to any Obligations. Issuing Bank does not assume any responsibility for any failure or delay in performance or any breach by any Borrower or other Person of any obligations under any LC Documents. Issuing Bank does not make to Lenders any express or implied warranty, representation or guaranty with respect to the Collateral, LC Documents or any Obligor. Issuing Bank shall not be responsible to any Lender for any recitals, statements, information, representations or warranties contained in, or for the execution, validity, genuineness, effectiveness or enforceability of any LC Documents; the validity, genuineness, enforceability, collectibility, value or sufficiency of any Collateral or the perfection of any Lien therein; or the assets, liabilities, financial condition, results of operations, business, creditworthiness or legal status of any Obligor. (d) No Issuing Bank Indemnitee shall be liable to any Lender or other Person for any action taken or omitted to be taken in connection with any Letter of Credit or LC Document except as a result of its gross negligence or willful misconduct. Issuing Bank may refrain from taking any action with respect to a Letter of Credit until it receives written instructions from Required Lenders. 2.2.3. Cash Collateral. If any LC Obligations, whether or not then due or payable, shall for any reason be outstanding at any time (a) that an Event of Default exists, (b) that Availability is less than zero, (c) after the Commitment Termination Date, or (d) within 20 Business Days prior to the Revolver Termination Date, then Borrowers shall, at Issuing

-45- Bank’s or Agent’s request, Cash Collateralize the stated amount of all outstanding Letters of Credit and pay to Issuing Bank the amount of all other LC Obligations. Borrowers shall, on demand by Issuing Bank or Agent from time to time, Cash Collateralize the Fronting Exposure of any Defaulting Lender. If Borrowers fail to provide any Cash Collateral as required hereunder, Lenders may (and shall upon direction of Agent) advance, as Revolver Loans, the amount of the Cash Collateral required (whether or not the Commitments have terminated, an Overadvance exists or the conditions in Section 6 are satisfied). 2.2.4. Resignation of Issuing Bank. Issuing Bank may resign at any time upon notice to Agent and Borrowers. On and after the effective date of such resignation, Issuing Bank shall have no obligation to issue, amend, renew, extend or otherwise modify any Letter of Credit, but shall continue to have all rights and other obligations of an Issuing Bank hereunder relating to any Letter of Credit issued by it prior to such date. Agent shall promptly appoint a replacement Issuing Bank, which, as long as no Default or Event of Default exists, shall be reasonably acceptable to Borrowers. SECTION 3. INTEREST, FEES AND CHARGES 3.1. Interest. 3.1.1. Rates and Payment of Interest. (a) The Obligations shall bear interest (i) if a Base Rate Loan, at the Base Rate in effect from time to time, plus the Applicable Margin for such Base Rate Loan; (ii) if a LIBOR Loan, at LIBOR for the applicable Interest Period, plus the Applicable Margin for LIBOR Loans; and (iii) if any other Obligation (including, to the extent permitted by law, interest not paid when due), at the Base Rate in effect from time to time, plus the Applicable Margin for the related Base Rate Loans. (b) During an Insolvency Proceeding with respect to any Borrower, or during any other Event of Default if Agent or Required Lenders in their discretion so elect, Obligations shall bear interest at the Default Rate (whether before or after any judgment). Each Borrower acknowledges that the cost and expense to Agent and Lenders due to an Event of Default are difficult to ascertain and that the Default Rate is fair and reasonable compensation for this. (c) Interest shall accrue from the date a Loan is advanced or Obligation is incurred or payable, until paid in full by Borrowers. Interest accrued on the Loans shall be due and payable in arrears, (i) on the first day of each month; (ii) on any date of prepayment, with respect to the principal amount of Loans being prepaid; and (iii) on the Commitment Termination Date. Interest accrued on any other Obligations shall be due and payable as provided in the Loan Documents and, if no payment date is specified, shall be due and payable on demand. Notwithstanding the foregoing, interest accrued at the Default Rate shall be due and payable on demand. 3.1.2. Application of LIBOR to Outstanding Loans. (a) Borrowers may on any Business Day, subject to delivery of a Notice of Conversion/Continuation, elect to convert any portion of the Base Rate Loans to, or to continue any LIBOR Loan at the end of its Interest Period as, a LIBOR Loan. During any

-46- Default or Event of Default, Agent may (and shall at the direction of Required Lenders) declare that no Loan may be made, converted or continued as a LIBOR Loan. (b) Whenever Borrowers desire to convert or continue Loans as LIBOR Loans, Borrower Agent shall give Agent a Notice of Conversion/Continuation, no later than 11:00 a.m. at least three Business Days before the requested conversion or continuation date. Promptly after receiving any such notice, Agent shall notify each Lender thereof. Each Notice of Conversion/Continuation shall be irrevocable, and shall specify the amount of Loans to be converted or continued, the conversion or continuation date (which shall be a Business Day), and the duration of the Interest Period (which shall be deemed to be 30 days if not specified). If, upon the expiration of any Interest Period in respect of any LIBOR Loans, Borrowers shall have failed to deliver a Notice of Conversion/Continuation, they shall be deemed to have elected to convert such Loans into Base Rate Loans. 3.1.3. Interest Periods. In connection with the making, conversion or continuation of any LIBOR Loans, Borrowers shall select an interest period (“Interest Period”) to apply, which interest period shall be 30, 60, 90 or 180 days; provided, however, that: (a) the Interest Period shall begin on the date the Loan is made or continued as, or converted into, a LIBOR Loan, and shall expire on the numerically corresponding day in the calendar month at its end; (b) if any Interest Period begins on a day for which there is no corresponding day in the calendar month at its end or if such corresponding day falls after the last Business Day of such month, then the Interest Period shall expire on the last Business Day of such month; and if any Interest Period would otherwise expire on a day that is not a Business Day, the period shall expire on the next Business Day; and (c) no Interest Period shall extend beyond the Revolver Termination Date. 3.1.4. Interest Rate Not Ascertainable. If Agent shall determine that on any date for determining LIBOR, due to any circumstance affecting the London interbank market, adequate and fair means do not exist for ascertaining such rate on the basis provided herein, then Agent shall immediately notify Borrowers of such determination. Until Agent notifies Borrowers that such circumstance no longer exists, the obligation of Lenders to make LIBOR Loans shall be suspended, and no further Loans may be converted into or continued as LIBOR Loans. 3.2. Fees. 3.2.1. Unused Line Fee. Borrowers shall pay to Agent, for the Pro Rata benefit of Lenders, a fee equal to the Unused Line Fee Rate times the amount by which the Revolver Commitments, minus the Senior Notes Availability Reserve for the period when in place, exceed the average daily balance of Revolver Loans and stated amount of Letters of Credit during any month. Such fee shall be payable in arrears, on the first day of each month and on the Commitment Termination Date. 3.2.2. LC Facility Fees. Borrowers shall pay (a) to Agent, for the Pro Rata benefit of Lenders, a fee equal to the Applicable Margin in effect for LIBOR Loans times the

-47- average daily stated amount of Letters of Credit, which fee shall be payable monthly in arrears, on the first day of each month; (b) to Agent, for its own account, a fronting fee equal to 0.125% per annum on the stated amount of each Letter of Credit, which fee shall be payable monthly in arrears, on the first day of each month; and (c) to Issuing Bank, for its own account, all customary charges associated with the issuance, amending, negotiating, payment, processing, transfer and administration of Letters of Credit, which charges shall be paid as and when incurred. During an Event of Default, the fee payable under clause (a) shall be increased by 2% per annum. 3.2.3. Fee Letters. Borrowers shall pay all fees set forth in any fee letter executed in connection with this Agreement. 3.3. Computation of Interest, Fees, Yield Protection. All interest, as well as fees and other charges calculated on a per annum basis, shall be computed for the actual days elapsed, based on a year of 360 days. Each determination by Agent of any interest, fees or interest rate hereunder shall be final, conclusive and binding for all purposes, absent manifest error. All fees shall be fully earned when due and shall not be subject to rebate, refund or proration. All fees payable under Section 3.2 are compensation for services and are not, and shall not be deemed to be, interest or any other charge for the use, forbearance or detention of money. A certificate as to amounts payable by Borrowers under Section 3.4, 3.7, 3.9 or 5.9, submitted to Borrower Agent by Agent or the affected Lender, as applicable, shall be final, conclusive and binding for all purposes, absent manifest error, and Borrowers shall pay such amounts to the appropriate party within 10 days following receipt of the certificate. 3.4. Reimbursement Obligations. Borrowers shall reimburse Agent for all Extraordinary Expenses. Borrowers shall also reimburse Agent for all reasonable legal, accounting, appraisal, consulting, and other fees, costs and expenses incurred by it in connection with (a) negotiation and preparation of any Loan Documents, including any amendment or other modification thereof; (b) administration of and actions relating to any Collateral, Loan Documents and transactions contemplated thereby, including any actions taken to perfect or maintain priority of Agent’s Liens on any Collateral, to maintain any insurance required hereunder or to verify Collateral; and (c) subject to the limits of Section 10.1.1(b), each inspection, audit or appraisal with respect to any Obligor or Collateral, whether prepared by Agent’s personnel or a third party. Unless specifically provided for otherwise in this Agreement or any other Loan Document, amounts payable under clauses (a) and (b) of the preceding sentence shall be limited to out-of-pocket amounts paid by the Agent. All legal, accounting and consulting fees shall be charged to Borrowers by Agent’s professionals at their full hourly rates, after giving effect to any applicable reduced or alternative fee billing arrangements that Agent may have with such professionals with respect to this transaction. In addition to the Extraordinary Expenses of Agent, upon the occurrence and during the continuance of an Event Default, Borrowers shall reimburse Lenders for the reasonable and documented fees, charges and disbursements of one counsel (and if necessary, of one local counsel in each other relevant jurisdiction (which may include a local counsel acting in each of multiple jurisdictions)) for the Lenders, as a whole, in connection with the enforcement, collection or protection of their respective rights under the Loan Documents, including all such expenses incurred during any workout, restructuring or Insolvency Proceeding; provided, that, notwithstanding anything to the contrary herein, in the event that there is a conflict of interest amongst the Lenders on the one hand or the Agent and the Lenders on the other hand, the Lenders may engage and be reimbursed for one additional counsel, subject to the foregoing limitations. If, for any reason (including

-48- inaccurate reporting on financial statements or a Compliance Certificate), it is determined that a higher Applicable Margin should have applied to a period than was actually applied, then the proper margin shall be applied retroactively and Borrowers shall immediately pay to Agent, for the Pro Rata benefit of Lenders, an amount equal to the difference between the amount of interest and fees that would have accrued using the proper margin and the amount actually paid. All amounts payable by Borrowers under this Section shall be due five (5) Business Days after demand. 3.5. Illegality. If any Lender determines that any Applicable Law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for any Lender or its applicable Lending Office to make, maintain or fund LIBOR Loans, or to determine or charge interest rates based upon LIBOR, or any Governmental Authority has imposed material restrictions on the authority of such Lender to purchase or sell, or to take deposits of, Dollars in the London interbank market, then, on notice thereof by such Lender to Agent, any obligation of such Lender to make or continue LIBOR Loans or to convert Base Rate Loans to LIBOR Loans shall be suspended until such Lender notifies Agent that the circumstances giving rise to such determination no longer exist. Upon delivery of such notice, Borrowers shall prepay or, if applicable, convert all LIBOR Loans of such Lender to Base Rate Loans, either on the last day of the Interest Period therefor, if such Lender may lawfully continue to maintain such LIBOR Loans to such day, or immediately, if such Lender may not lawfully continue to maintain such LIBOR Loans. Upon any such prepayment or conversion, Borrowers shall also pay accrued interest on the amount so prepaid or converted. 3.6. Inability to Determine Rates. If Required Lenders notify Agent in connection with a request for a Borrowing of, or conversion to or continuation of, a LIBOR Loan that (a) Dollar deposits are not being offered to banks in the London interbank Eurodollar market for the applicable amount and Interest Period of such Loan, (b) adequate and reasonable means do not exist for determining LIBOR for the requested Interest Period, or (c) LIBOR for the requested Interest Period does not adequately and fairly reflect the cost to such Lenders of funding such Loan, then Agent will promptly so notify Borrower Agent and each Lender. Thereafter, the obligation of Lenders to make or maintain LIBOR Loans shall be suspended until Agent (upon instruction by Required Lenders) revokes such notice. Upon receipt of such notice, Borrower Agent may revoke any pending request for a Borrowing of, conversion to or continuation of a LIBOR Loan or, failing that, will be deemed to have submitted a request for a Base Rate Loan. 3.7. Increased Costs; Capital Adequacy. 3.7.1. Change in Law. If any Change in Law shall: (a) impose, modify or deem applicable any reserve, liquidity, special deposit, compulsory loan, insurance charge or similar requirement against assets of, deposits with or for the account of, or credit extended or participated in by, any Lender (except any reserve requirement reflected in LIBOR) or Issuing Bank; (b) subject any Lender or Issuing Bank to any Tax with respect to any Loan, Loan Document, Letter of Credit or participation in LC Obligations, or change the basis of taxation of payments to such Lender or Issuing Bank in respect thereof (except for Indemnified

-49- Taxes or Other Taxes covered by Section 5.9 and the imposition of, or any change in the rate of, any Excluded Tax payable by such Lender or Issuing Bank); or (c) impose on any Lender, Issuing Bank or interbank market any other condition, cost or expense affecting any Loan, Loan Document, Letter of Credit, participation in LC Obligations, or Commitment; and the result thereof shall be to increase the cost to such Lender of making or maintaining any Loan or Commitment, or to increase the cost to such Lender or Issuing Bank of participating in, issuing or maintaining any Letter of Credit, or to reduce the amount of any sum received or receivable by such Lender or Issuing Bank hereunder (whether of principal, interest or any other amount) then, upon request of such Lender or Issuing Bank, Borrowers will pay to such Lender or Issuing Bank, as applicable, such additional amount or amounts as will compensate such Lender or Issuing Bank, as applicable, for such additional costs incurred or reduction suffered. 3.7.2. Capital Adequacy. If any Lender or Issuing Bank determines that any Change in Law affecting such Lender or Issuing Bank or any Lending Office of such Lender or such Lender’s or Issuing Bank’s holding company, if any, regarding capital or liquidity requirements has or would have the effect of reducing the rate of return on such Lender’s, Issuing Bank’s or holding company’s capital as a consequence of this Agreement, or such Lender’s or Issuing Bank’s Commitments, Loans, Letters of Credit or participations in LC Obligations, to a level below that which such Lender, Issuing Bank or holding company could have achieved but for such Change in Law (taking into consideration such Lender’s, Issuing Bank’s and holding company’s policies with respect to capital adequacy and liquidity), then from time to time Borrowers will pay to such Lender or Issuing Bank, as the case may be, such additional amount or amounts as will compensate it or its holding company for any such reduction suffered. 3.7.3. Compensation. Failure or delay on the part of any Lender or Issuing Bank to demand compensation pursuant to this Section shall not constitute a waiver of its right to demand such compensation, but Borrowers shall not be required to compensate a Lender or Issuing Bank for any increased costs incurred or reductions suffered more than nine months prior to the date that the Lender or Issuing Bank notifies Borrower Agent of the Change in Law giving rise to such increased costs or reductions and of such Lender’s or Issuing Bank’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the nine-month period referred to above shall be extended to include the period of retroactive effect thereof). 3.8. Mitigation; Replacement of Lenders under Certain Circumstances. If any Lender gives a notice under Section 3.5 or requests compensation under Section 3.7, or if Borrowers are required to pay additional amounts with respect to a Lender under Section 5.9, then such Lender shall use reasonable efforts to designate a different Lending Office or to assign its rights and obligations hereunder to another of its offices, branches or Affiliates, if, in the judgment of such Lender, such designation or assignment (a) would eliminate the need for such notice or reduce amounts payable or to be withheld in the future, as applicable; and (b) would not subject the Lender to any unreimbursed cost or expense and would not otherwise be disadvantageous to it or unlawful. Borrowers shall pay all reasonable costs and expenses incurred by any Lender in connection with any such designation or assignment. Borrowers shall be permitted to replace any Lender that gives a notice under Section 3.5 or 3.6 or requests

-50- compensation under Section 3.7, or if Borrowers are required to pay additional amounts with respect to a Lender under Section 5.9, with a replacement lender; provided that (i) no Event of Default shall have occurred and be continuing at the time of such replacement, (ii) the replacement lender shall purchase, at par, all Loans and other amounts owing to such replaced Lender on or prior to the date of replacement, (iii) the replacement lender, if not an Eligible Assignee, shall be satisfactory to the Agent, (iv) the replaced Lender shall be obligated to make such replacement in accordance with the provisions of Section 13.3, (v) the Borrowers shall pay all additional amounts (if any) required pursuant to Section 3.5 or 3.7, as the case may be, in respect of any period prior to the date on which such replacement shall be consummated, and (vi) any such replacement shall not be deemed to be a waiver of any rights that the Borrowers, the Agent or any other Lender shall have against the replaced Lender. 3.9. Funding Losses. If for any reason (other than default by a Lender) (a) any Borrowing of, or conversion to or continuation of, a LIBOR Loan does not occur on the date specified therefor in a Notice of Borrowing or Notice of Conversion/Continuation (whether or not withdrawn), (b) any repayment or conversion of a LIBOR Loan occurs on a day other than the end of its Interest Period, (c) Borrowers fail to repay a LIBOR Loan when required hereunder, or (d) a Lender (other than a Defaulting Lender) is required to assign a LIBOR Loan prior to the end of its Interest Period pursuant to Section 3.8 or 13.4, then Borrowers shall pay to Agent its customary administrative charge and to each Lender all resulting losses and expenses, including loss of anticipated profits and any loss or expense arising from liquidation or redeployment of funds or from fees payable to terminate deposits of matching funds. Lenders shall not be required to purchase Dollar deposits in any interbank or offshore Dollar market to fund any LIBOR Loan, but this Section shall apply as if each Lender had purchased such deposits. 3.10. Maximum Interest. Regardless of any provision contained in any of the Loan Documents, in no contingency or event whatsoever shall the aggregate of all amounts that are contracted for, charged or received by Agent or any Lender pursuant to the terms of this Agreement or any of the other Loan Documents and that are deemed interest under Applicable Law exceed the highest rate permissible under any Applicable Law (the “Maximum Rate”). No agreements, conditions, provisions or stipulations contained in this Agreement or any of the other Loan Documents or the exercise by Agent of the right to accelerate the payment or the maturity of all or any portion of the Obligations, or the exercise of any option whatsoever contained in any of the Loan Documents, or the prepayment by any Obligor of any of the Obligations, or the occurrence of any contingency whatsoever, shall entitle Agent or Lenders to charge or receive in any event, interest or any charges, amounts, premiums or fees deemed interest by Applicable Law (such interest, charges, amounts, premiums and fees referred to herein collectively as “Interest”) in excess of the Maximum Rate and in no event shall any Obligor be obligated to pay Interest exceeding such Maximum Rate, and all agreements, conditions or stipulations, if any, which may in any event or contingency whatsoever operate to bind, obligate or compel any Obligor to pay Interest exceeding the Maximum Rate shall be without binding force or effect, at law or in equity, to the extent only of the excess of Interest over such Maximum Rate. If any Interest is charged or received with respect to the Obligations in excess of the Maximum Rate (“Excess”), each Obligor stipulates that any such charge or receipt shall be the result of an accident and bona fide error, and such Excess, to the extent received, shall be applied first to reduce the principal Obligations and the balance, if any, returned to the Obligors, it being the intent of the parties hereto not to enter into an usurious or otherwise illegal relationship. The right to accelerate the maturity of any of the Obligations does

-51- not include the right to accelerate any Interest that has not otherwise accrued on the date of such acceleration, and neither Agent nor any Lender intends to collect any unearned Interest in the event of any such acceleration. Each Obligor recognizes that, with fluctuations in the rates of interest set forth in this Agreement, and the Maximum Rate, such an unintentional result could inadvertently occur. All monies paid to Agent or any Lender hereunder or under any of the other Loan Documents, whether at maturity or by prepayment, shall be subject to any rebate of unearned Interest as and to the extent required by Applicable Law. By the execution of this Agreement, each Obligor covenants that (i) the credit or return of any Excess shall constitute the acceptance by each Obligor of such Excess, and (ii) each Obligor shall not seek or pursue any other remedy, legal or equitable, against Agent or any Lender, based in whole or in part upon contracting for, charging or receiving any Interest in excess of the Maximum Rate. For the purpose of determining whether or not any Excess has been contracted for, charged or received by Agent or any Lender, all Interest at any time contracted for, charged or received from any Obligor in connection with any of the Loan Documents shall, to the extent permitted by Applicable Law, be amortized, prorated, allocated and spread in equal parts throughout the full term of the Obligations. Obligors, Agent and Lenders shall, to the maximum extent permitted under Applicable Law, (i) characterize any non-principal payment as an expense, fee or premium rather than as Interest and (ii) exclude voluntary prepayments and the effects thereof. The provisions of this Section 3.10 shall be deemed to be incorporated into every Loan Document (whether or not any provision of this Section is referred to therein). All such Loan Documents and communications relating to any Interest owed by any Obligor and all figures set forth therein shall, for the sole purpose of computing the extent of Obligations, be automatically recomputed by the Obligors, and by any court considering the same, to give effect to the adjustments or credits required by this Section 3.10. SECTION 4. LOAN ADMINISTRATION 4.1. Manner of Borrowing and Funding Revolver Loans. 4.1.1. Notice of Borrowing. (a) Whenever Borrowers desire funding of a Borrowing of Revolver Loans, Borrower Agent shall give Agent a Notice of Borrowing. Such notice must be received by Agent no later than 2:00 p.m. (i) on the Business Day of the requested funding date, in the case of Base Rate Loans, and (ii) at least three Business Days prior to the requested funding date, in the case of LIBOR Loans. Notices received after 2:00 p.m. shall be deemed received on the next Business Day. Each Notice of Borrowing shall be irrevocable and shall specify (A) the amount of the Borrowing, (B) the requested funding date (which must be a Business Day), (C) whether the Borrowing is to be made as Base Rate Loans or LIBOR Loans, and (D) in the case of LIBOR Loans, the duration of the applicable Interest Period (which shall be deemed to be 30 days if not specified). (b) Unless payment is otherwise timely made by Borrowers, the becoming due of any Obligations (whether principal, interest, fees or other charges, including Extraordinary Expenses, LC Obligations, Cash Collateral and Secured Bank Product Obligations) shall be deemed to be a request for Base Rate Revolver Loans on the due date, in the amount of such Obligations. The proceeds of such Revolver Loans shall be disbursed as direct payment of the relevant Obligation. In addition, Agent may, at its option, charge such

-52- Obligations against any operating, investment or other account of a Borrower maintained with Agent or any of its Affiliates. (c) If Borrowers maintain any disbursement account with Agent or any Affiliate of Agent, then presentation for payment of any Payment Item when there are insufficient funds to cover it shall be deemed to be a request for a Base Rate Revolver Loan on the date of such presentation, in the amount of the Payment Item. The proceeds of such Revolver Loan may be disbursed directly to the disbursement account. 4.1.2. Fundings by Lenders. Each Lender shall timely honor its Revolver Commitment by funding its Pro Rata share of each Borrowing of Revolver Loans that is properly requested hereunder. Except for Borrowings to be made as Swingline Loans, Agent shall endeavor to notify Lenders of each Notice of Borrowing (or deemed request for a Borrowing) by 3:00 p.m. on the proposed funding date for Base Rate Loans or by 3:00 p.m. at least two Business Days before any proposed funding of LIBOR Loans. Each Lender shall fund to Agent such Lender’s Pro Rata share of the Borrowing to the account specified by Agent in immediately available funds not later than 4:00 p.m. on the requested funding date, unless Agent’s notice is received after the times provided above, in which case Lender shall fund its Pro Rata share by 11:00 a.m. on the next Business Day. Subject to its receipt of such amounts from Lenders, Agent shall disburse the proceeds of the Revolver Loans as directed by Borrower Agent. Unless Agent shall have received (in sufficient time to act) written notice from a Lender that it does not intend to fund its Pro Rata share of a Borrowing, Agent may assume that such Lender has deposited or promptly will deposit its share with Agent, and Agent may disburse a corresponding amount to Borrowers. If a Lender’s share of any Borrowing or of any settlement pursuant to Section 4.1.3(b) is not received by Agent, then Borrowers agree to repay to Agent on demand the amount of such share, together with interest thereon from the date disbursed until repaid, at the rate applicable to the Borrowing. 4.1.3. Swingline Loans; Settlement. (a) Agent may, but shall not be obligated to, advance Swingline Loans to Borrowers, up to an aggregate outstanding amount of $15,000,000, unless the funding is specifically required to be made by all Lenders hereunder. Each Swingline Loan shall constitute a Revolver Loan for all purposes, except that payments thereon shall be made to Agent for its own account. The obligation of Borrowers to repay Swingline Loans shall be evidenced by the records of Agent and need not be evidenced by any promissory note. (b) Settlement of Swingline Loans and other Revolver Loans among Lenders and Agent shall take place on a date determined from time to time by Agent (but at least weekly), in accordance with the Settlement Report delivered by Agent to Lenders. Between settlement dates, Agent may in its discretion apply payments on Revolver Loans to Swingline Loans, regardless of any designation by Borrower or any provision herein to the contrary. Each Lender’s obligation to make settlements with Agent is absolute and unconditional, without offset, counterclaim or other defense, and whether or not the Commitments have terminated, an Overadvance exists or the conditions in Section 6 are satisfied. If, due to an Insolvency Proceeding with respect to a Borrower or otherwise, any Swingline Loan may not be settled among Lenders hereunder, then each Lender shall be deemed to have purchased from Agent a Pro Rata participation in such Loan and shall transfer the amount of such participation to Agent, in immediately available funds, within one Business Day after Agent’s request therefor.

-53- 4.1.4. Notices. Borrowers may request, convert or continue Loans, select interest rates and transfer funds based on telephonic or e-mailed instructions to Agent. Borrowers shall confirm each such request by prompt delivery to Agent of a Notice of Borrowing or Notice of Conversion/Continuation, if applicable, but if it differs materially from the action taken by Agent or Lenders, the records of Agent and Lenders shall govern. Neither Agent nor any Lender shall have any liability for any loss suffered by a Borrower as a result of Agent or any Lender acting upon its understanding of telephonic or e-mailed instructions from a person believed in good faith by Agent or any Lender to be a person authorized to give such instructions on a Borrower’s behalf. 4.2. Defaulting Lender. 4.2.1. Reallocation of Pro Rata Share; Amendments. For purposes of determining Lenders’ obligations to fund or participate in Loans or Letters of Credit, Agent may exclude the Commitments and Loans of any Defaulting Lender(s) from the calculation of Pro Rata shares; provided, however, that in no event will any Lender be required to fund or participate in Loans or Letters of Credit if as a result of such funding or participation the aggregate amount of such Lender’s Revolving Loans and participations in LC Obligations would exceed its Commitment. A Defaulting Lender shall have no right to vote on any amendment, waiver or other modification of a Loan Document, except as provided in Section 15.1.1(c). 4.2.2. Payments; Fees. Agent may, in its discretion, receive and retain any amounts payable to a Defaulting Lender under the Loan Documents, and a Defaulting Lender shall be deemed to have assigned to Agent such amounts until all Obligations owing to Agent, non-Defaulting Lenders and other Secured Parties have been paid in full. Agent may apply such amounts to the Defaulting Lender’s defaulted obligations, use the funds to Cash Collateralize such Lender’s Fronting Exposure, or readvance the amounts to Borrowers hereunder. A Lender shall not be entitled to receive any fees accruing hereunder during the period in which it is a Defaulting Lender, and the unfunded portion of its Commitment shall be disregarded for purposes of calculating the unused line fee under Section 3.2.1. If any LC Obligations owing to a Defaulted Lender are reallocated to other Lenders, fees attributable to such LC Obligations under Section 3.2.2 shall be paid to such Lenders. Agent shall be paid all fees attributable to LC Obligations that are not reallocated. 4.2.3. Cure. Borrowers, Agent and Issuing Bank may agree in writing that a Lender is no longer a Defaulting Lender. At such time, Pro Rata shares shall be reallocated without exclusion of such Lender’s Commitments and Loans, and all outstanding Revolver Loans, LC Obligations and other exposures under the Revolver Commitments shall be reallocated among Lenders and settled by Agent (with appropriate payments by the reinstated Lender) in accordance with the readjusted Pro Rata shares. Unless expressly agreed by Borrowers, Agent and Issuing Bank, no reinstatement of a Defaulting Lender shall constitute a waiver or release of claims against such Lender. The failure of any Lender to fund a Loan, to make a payment in respect of LC Obligations or otherwise to perform its obligations hereunder shall not relieve any other Lender of its obligations, and no Lender shall be responsible for default by another Lender. 4.3. Number and Amount of LIBOR Loans; Determination of Rate. Each Borrowing of LIBOR Loans when made shall be in a minimum amount of $1,000,000, plus any increment of $500,000 in excess thereof. No more than ten (10) Borrowings of LIBOR Loans

-54- may be outstanding at any time, and all LIBOR Loans having the same length and beginning date of their Interest Periods shall be aggregated together and considered one Borrowing for this purpose. Upon determining LIBOR for any Interest Period requested by Borrowers, Agent shall promptly notify Borrowers thereof by telephone or electronically and, if requested by Borrowers, shall confirm any telephonic notice in writing. 4.4. Borrower Agent. Each Borrower hereby designates US Concrete (“Borrower Agent”) as its representative and agent for all purposes under the Loan Documents, including requests for Loans and Letters of Credit, designation of interest rates, delivery or receipt of communications, preparation and delivery of Borrowing Base and financial reports, receipt and payment of Obligations, requests for waivers, amendments or other accommodations, actions under the Loan Documents (including in respect of compliance with covenants), and all other dealings with Agent, Issuing Bank or any Lender. Borrower Agent hereby accepts such appointment. Agent and Lenders shall be entitled to rely upon, and shall be fully protected in relying upon, any notice or communication (including any notice of borrowing) delivered by Borrower Agent on behalf of any Borrower. Agent and Lenders may give any notice or communication with a Borrower hereunder to Borrower Agent on behalf of such Borrower. Each of Agent, Issuing Bank and Lenders shall have the right, in its discretion, to deal exclusively with Borrower Agent for any or all purposes under the Loan Documents. Each Borrower agrees that any notice, election, communication, representation, agreement or undertaking made on its behalf by Borrower Agent shall be binding upon and enforceable against it. 4.5. One Obligation. The Loans, LC Obligations and other Obligations constitute one general obligation of Borrowers and are secured by Agent’s Lien on all Collateral; provided, however, that Agent and each Lender shall be deemed to be a creditor of, and the holder of a separate claim against, each Borrower to the extent of any Obligations jointly or severally owed by such Borrower. 4.6. Effect of Termination. On the effective date of the termination of all Commitments, the outstanding Obligations shall be immediately due and payable, and any Lender may terminate its and its Affiliates’ Bank Products (including, only with the consent of Agent, any Cash Management Services). Until Full Payment of the outstanding Obligations, all undertakings of Borrowers contained in the Loan Documents shall continue, and Agent shall retain its Liens in the Collateral and all of its rights and remedies under the Loan Documents. Agent shall not be required to terminate its Liens unless it receives Cash Collateral or a written agreement, in each case satisfactory to it, protecting Agent and Lenders from the dishonor or return of any Payment Items previously applied to the Obligations. Sections 3.4, 3.7, 3.9, 5.5, 5.9, 5.10, 12, 14.2, this Section, and each indemnity or waiver given by an Obligor or Lender in any Loan Document, shall survive Full Payment of the Obligations. SECTION 5. PAYMENTS 5.1. General Payment Provisions. All payments of Obligations shall be made in Dollars, without offset, counterclaim or defense of any kind, free of (and without deduction for) any Taxes, and in immediately available funds, not later than 1:00 p.m. on the due date. Any payment after such time shall be deemed made on the next Business Day. Any payment of a LIBOR Loan prior to the end of its Interest Period shall be accompanied by all amounts due under Section 3.9. Borrowers agree that Agent shall have the continuing, exclusive right to

-55- apply and reapply payments and proceeds of Collateral against the outstanding Obligations, in such manner as Agent deems advisable, but whenever possible, any prepayment of Loans shall be applied first to Base Rate Loans and then to LIBOR Loans. 5.2. Repayment of Revolver Loans. Revolver Loans shall be due and payable in full on the Revolver Termination Date, unless payment is sooner required hereunder. Revolver Loans may be prepaid from time to time, without penalty or premium. Concurrently with (a) any Asset Disposition of ABL Priority Collateral or, after the occurrence of the Machinery Qualifying Date, Machinery (i) that occurs during a Trigger Period or the immediate effect of which disposition will be the commencement of a Trigger Period or (ii) which disposition is not permitted by the provisions of this Agreement or (b) any other Asset Disposition of (i) Trucks that have a fair market or book value (whichever is more) of at least $1,000,000 or (ii) Inventory that has a fair market or book value (whichever is more) of at least $1,000,000, or (iii) Accounts that have a fair market or book value (whichever is more) of at least $250,000 or (iv) after the occurrence of the Machinery Qualifying Date, Machinery that has a fair market or book value (whichever is more) of at least $1,000,000, Borrowers shall prepay Revolver Loans in an amount equal to the Net Proceeds of such Asset Disposition, provided that any such prepayment shall not waive any Default or Event of Default otherwise arising under this Agreement due to such Asset Disposition. Subject to Section 2.1.5, notwithstanding anything herein to the contrary, if an Overadvance exists, Borrowers shall, on the sooner of Agent’s demand or the first Business Day after any Borrower has knowledge thereof, repay the outstanding Revolver Loans in an amount sufficient to reduce the principal balance of Revolver Loans to the Borrowing Base. 5.3. Payment of Other Obligations. Obligations other than Loans and LC Obligations, shall be paid by Borrowers as provided in the Loan Documents or, if no payment date is specified, within five (5) Business Days of demand. 5.4. Marshaling; Payments Set Aside. None of Agent or Lenders shall be under any obligation to marshal any assets in favor of any Obligor or against any Obligations. If any payment by or on behalf of Borrowers is made to Agent, Issuing Bank or any Lender, or Agent, Issuing Bank or any Lender exercises a right of setoff, and such payment or the proceeds of such setoff or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required (including pursuant to any settlement entered into by Agent, Issuing Bank or such Lender in its discretion) to be repaid to a trustee, receiver or any other Person, then to the extent of such recovery, the Obligation originally intended to be satisfied, and all Liens, rights and remedies relating thereto, shall be revived and continued in full force and effect as if such payment had not been made or such setoff had not occurred. 5.5. Application and Allocation of Payments. 5.5.1. Application. Payments made by Borrowers hereunder shall be applied (a) first, as specifically required hereby; (b) second, to Obligations then due and owing; (c) third, to other Obligations specified by Borrowers; and (d) fourth, as determined by Agent in its Permitted Discretion. 5.5.2. Post-Default Allocation. Notwithstanding anything in any Loan Document to the contrary, during an Event of Default, monies to be applied to the Obligations, whether arising from payments by Obligors, realization on Collateral (subject to the Intercreditor Agreement), setoff or otherwise, shall be allocated as follows:

-56- (a) first, to all costs and expenses, including Extraordinary Expenses, owing to Agent; (b) second, to all amounts owing to Agent on Swingline Loans; (c) third, to all amounts owing to Issuing Bank; (d) fourth, to all Obligations constituting fees (other than Secured Bank Product Obligations); (e) fifth, to all Obligations constituting interest (other than Secured Bank Product Obligations); (f) sixth, to Cash Collateralization of LC Obligations; (g) seventh, to all Loans, and to Secured Bank Product Obligations arising under Hedging Agreements (including Cash Collateralization thereof) up to the amount of reserves existing therefor; (h) eighth, to all other Secured Bank Product Obligations; and (i) last, to all remaining Obligations. Amounts shall be applied to payment of each category of Obligations only after Full Payment of all preceding categories. If amounts are insufficient to satisfy a category, Obligations in the category shall be paid on a pro rata basis. Monies and proceeds obtained from an Obligor shall not be applied to its Excluded Swap Obligations, but appropriate adjustments shall be made with respect to amounts obtained from other Obligors to preserve the allocations in any applicable category. Amounts distributed with respect to any Secured Bank Product Obligation shall be calculated using the methodology reported to Agent for such Obligation (but no greater than the maximum amount reported to Agent). Agent shall have no obligation to calculate the amount of any Secured Bank Product Obligation and may request a reasonably detailed calculation thereof from the applicable Secured Bank Product Provider. If the provider fails to deliver the calculation within five days following request, Agent may assume the amount is zero. The allocations set forth in this Section are solely to determine the rights and priorities among Secured Parties, and may be changed by agreement among them without the consent of any Obligor. This Section is not for the benefit of or enforceable by any Obligor, and each Borrower irrevocably waives the right to direct the application of any payments or Collateral proceeds subject to this Section. 5.5.3. Erroneous Application. Agent shall not be liable for any application of amounts made by it in good faith and, if any such application is subsequently determined to have been made in error, the sole recourse of any Lender or other Person to which such amount should have been made shall be to recover the amount from the Person that actually received it (and, if such amount was received by any Lender, such Lender hereby agrees to return it). 5.6. Dominion Account. The ledger balance in the main Dominion Account as of the end of a Business Day shall be applied to the Obligations at the beginning of the next Business Day, during any FCCR Trigger Period. If, as a result of such application, a credit balance exists,

-57- the balance shall not accrue interest in favor of Borrowers and shall be made available to Borrowers as long as no Default or Event of Default exists. 5.7. Account Stated. The Agent shall maintain in accordance with its usual and customary practices account(s) evidencing the Debt of Borrowers hereunder. Any failure of Agent to record anything in a loan account, or any error in doing so, shall not limit or otherwise affect the obligation of Borrowers to pay any amount owing hereunder. Entries made in a loan account shall constitute presumptive evidence of the information contained therein. If any information contained in a loan account is provided to or inspected by any Person, the information shall be conclusive and binding on such Person for all purposes absent manifest error, except to the extent such Person notifies Agent in writing within 30 days after receipt or inspection that specific information is subject to dispute. 5.8. Taxes. 5.8.1. Payments Free of Taxes. All payments by Obligors of Obligations shall be free and clear of and without reduction for any Taxes. If Applicable Law requires any Obligor or Agent to withhold or deduct any Tax (including backup withholding or withholding Tax), the withholding or deduction shall be based on information provided pursuant to Section 5.9 and Agent shall pay the amount withheld or deducted to the relevant Governmental Authority. If the withholding or deduction is made on account of Indemnified Taxes or Other Taxes, the sum payable by Borrowers shall be increased so that Agent, Lender or Issuing Bank, as applicable, receives an amount equal to the sum it would have received if no such withholding or deduction (including deductions applicable to additional sums payable under this Section) had been made. Without limiting the foregoing, Borrowers shall timely pay all Other Taxes to the relevant Governmental Authorities. 5.8.2. Payment. Borrowers shall indemnify, hold harmless and reimburse (within 10 days after demand therefor) Agent, Lenders and Issuing Bank for any Indemnified Taxes or Other Taxes (including those attributable to amounts payable under this Section but excluding any amounts directly attributable to such indemnitee’s gross negligence or willful misconduct) withheld or deducted by any Obligor or Agent, or paid by Agent, any Lender or Issuing Bank, with respect to any Obligations, Letters of Credit or Loan Documents, whether or not such Taxes were properly asserted by the relevant Governmental Authority, and including all penalties, interest and reasonable expenses relating thereto, as well as any amount that a Lender or Issuing Bank fails to pay indefeasibly to Agent under Section 5.9. A certificate as to the amount of any such payment or liability delivered to Borrower Agent by Agent, or by a Lender or Issuing Bank (with a copy to Agent), shall be conclusive, absent manifest error. As soon as practicable after any payment of Taxes by a Borrower, Borrower Agent shall deliver to Agent a receipt from the Governmental Authority or other evidence of payment satisfactory to Agent. 5.9. Lender Tax Information. 5.9.1. Status of Lenders. Each Lender shall deliver documentation and information to Agent and Borrower Agent, at the times and in form required by Applicable Law or reasonably requested by Agent or Borrower Agent, sufficient to permit Agent or Borrowers to determine (a) whether or not payments made with respect to Obligations are subject to Taxes, (b) if applicable, the required rate of withholding or deduction, and (c) such Lender’s entitlement to any available exemption from, or reduction of, applicable Taxes for such payments or

-58- otherwise to establish such Lender’s status for withholding tax purposes in the applicable jurisdiction. 5.9.2. Documentation. If a Borrower is resident for tax purposes in the United States, any Lender that is a “United States person” within the meaning of section 7701(a)(30) of the Code shall deliver to Agent and Borrower Agent IRS Form W-9 or such other documentation or information prescribed by Applicable Law or reasonably requested by Agent or Borrower Agent to determine whether such Lender is subject to backup withholding or information reporting requirements. If any Foreign Lender is entitled to any exemption from or reduction of withholding tax for payments with respect to the Obligations, it shall deliver to Agent and Borrower Agent, on or prior to the date on which it becomes a Lender hereunder (and from time to time thereafter upon request by Agent or Borrower Agent, but only if such Foreign Lender is legally entitled to do so), (a) IRS Form W-8BEN claiming eligibility for benefits of an income tax treaty to which the United States is a party; (b) IRS Form W-8ECI; (c) IRS Form W-8IMY and all required supporting documentation; (d) in the case of a Foreign Lender claiming the benefits of the exemption for portfolio interest under section 881(c) of the Code, IRS Form W- 8BEN and a certificate showing such Foreign Lender is not (i) a “bank” within the meaning of section 881(c)(3)(A) of the Code, (ii) a “10 percent shareholder” of any Obligor within the meaning of section 881(c)(3)(B) of the Code, or (iii) a “controlled foreign corporation” described in section 881(c)(3)(C) of the Code; or (e) any other form prescribed by Applicable Law as a basis for claiming exemption from or a reduction in withholding tax, together with such supplementary documentation necessary to allow Agent and Borrowers to determine the withholding or deduction required to be made. 5.9.3. Lender Obligations. Each Lender and Issuing Bank shall promptly notify Borrowers and Agent of any change in circumstances that would change any claimed Tax exemption or reduction. Each Lender and Issuing Bank shall indemnify, hold harmless and reimburse (within 10 days after demand therefor) Borrowers and Agent for any Taxes, losses, claims, liabilities, penalties, interest and expenses (including reasonable attorneys’ fees) incurred by or asserted against a Borrower or Agent by any Governmental Authority due to such Lender’s or Issuing Bank’s failure to deliver, or inaccuracy or deficiency in, any documentation required to be delivered by it pursuant to this Section. Each Lender and Issuing Bank authorizes Agent to set off any amounts due to Agent under this Section against any amounts payable to such Lender or Issuing Bank under any Loan Document. 5.10. Nature and Extent of Each Borrower’s Liability. 5.10.1. Joint and Several Liability. Each Borrower agrees that it is jointly and severally liable for, and absolutely and unconditionally guarantees to Agent and Lenders the prompt payment and performance of, all Obligations and all agreements under the Loan Documents, except its Excluded Swap Obligations. Each Borrower agrees that its guaranty obligations hereunder constitute a continuing guaranty of payment and not of collection, that such obligations shall not be discharged until Full Payment of the Obligations, and that such obligations are absolute and unconditional, irrespective of (a) the genuineness, validity, regularity, enforceability, subordination or any future modification of, or change in, any Obligations or Loan Document, or any other document, instrument or agreement to which any Obligor is or may become a party or be bound; (b) the absence of any action to enforce this Agreement (including this Section) or any other Loan Document, or any waiver, consent or indulgence of any kind by Agent or any Lender with respect thereto; (c) the existence, value or

-59- condition of, or failure to perfect a Lien or to preserve rights against, any security or guaranty for the Obligations or any action, or the absence of any action, by Agent or any Lender in respect thereof (including the release of any security or guaranty); (d) the insolvency of any Obligor; (e) any election by Agent or any Lender in an Insolvency Proceeding for the application of Section 1111(b)(2) of the Bankruptcy Code; (f) any borrowing or grant of a Lien by any other Borrower, as debtor-in-possession under Section 364 of the Bankruptcy Code or otherwise; (g) the disallowance of any claims of Agent or any Lender against any Obligor for the repayment of any Obligations under Section 502 of the Bankruptcy Code or otherwise; or (h) any other action or circumstances that might otherwise constitute a legal or equitable discharge or defense of a surety or guarantor, except Full Payment of all Obligations. 5.10.2. Waivers. (a) Each Borrower expressly waives all rights that it may have now or in the future under any statute, at common law, in equity or otherwise, to compel Agent or Lenders to marshal assets or to proceed against any Obligor, other Person or security for the payment or performance of any Obligations before, or as a condition to, proceeding against such Borrower. Each Borrower waives all defenses available to a surety, guarantor or accommodation co-Obligor other than Full Payment of all Obligations and waives, to the maximum extent permitted by law, any right to revoke any guaranty of any Obligations as long as it is a Borrower. It is agreed among each Borrower, Agent and Lenders that the provisions of this Section 5.10 are of the essence of the transaction contemplated by the Loan Documents and that, but for such provisions, Agent and Lenders would decline to make Loans and issue Letters of Credit. Each Borrower acknowledges that its guaranty pursuant to this Section is necessary to the conduct and promotion of its business, and can be expected to benefit such business. (b) Agent may, in its discretion, pursue such rights and remedies as it deems appropriate, including realization upon Collateral by judicial foreclosure or nonjudicial sale or enforcement, without affecting any rights and remedies under this Section 5.10. If, in taking any action in connection with the exercise of any rights or remedies, Agent or any Lender shall forfeit any other rights or remedies, including the right to enter a deficiency judgment against any Borrower or other Person, whether because of any Applicable Laws pertaining to “election of remedies” or otherwise, each Borrower consents to such action and waives any claim based upon it, even if the action may result in loss of any rights of subrogation that any Borrower might otherwise have had. Any election of remedies that results in denial or impairment of the right of Agent or any Lender to seek a deficiency judgment against any Borrower shall not impair any other Borrower’s obligation to pay the full amount of the Obligations. Each Borrower waives all rights and defenses arising out of an election of remedies, such as nonjudicial foreclosure with respect to any security for the Obligations, even though that election of remedies destroys such Borrower’s rights of subrogation against any other Person. Agent or any Lender may bid all or a portion of the Obligations at any foreclosure, trustee or other sale, including any private sale, and the amount of such bid need not be paid by Agent but shall be credited against the Obligations. The amount of the successful bid at any such sale, whether Agent or any other Person is the successful bidder, shall be conclusively deemed to be the fair market value of the Collateral, and the difference between such bid amount and the remaining balance of the Obligations shall be conclusively deemed to be the amount of the Obligations guaranteed under this Section 5.10, notwithstanding that any present or future law or court decision may have the effect of reducing the amount of any deficiency claim to which Agent or any Lender might otherwise be entitled but for such bidding at any such sale.

-60- 5.10.3. Extent of Liability; Contribution. (a) Notwithstanding anything herein to the contrary, each Borrower’s liability under this Section 5.10 shall be limited to the greater of (i) all amounts for which such Borrower is primarily liable, as described below, and (ii) such Borrower’s Allocable Amount. (b) If any Borrower makes a payment under this Section 5.10 of any Obligations (other than amounts for which such Borrower is primarily liable) (a “Guarantor Payment”) that, taking into account all other Guarantor Payments previously or concurrently made by any other Borrower, exceeds the amount that such Borrower would otherwise have paid if each Borrower had paid the aggregate Obligations satisfied by such Guarantor Payments in the same proportion that such Borrower’s Allocable Amount bore to the total Allocable Amounts of all Borrowers, then such Borrower shall be entitled to receive contribution and indemnification payments from, and to be reimbursed by, each other Borrower for the amount of such excess, pro rata based upon their respective Allocable Amounts in effect immediately prior to such Guarantor Payment. The “Allocable Amount” for any Borrower shall be the maximum amount that could then be recovered from such Borrower under this Section 5.10 without rendering such payment voidable under Section 548 of the Bankruptcy Code or under any applicable state fraudulent transfer or conveyance act, or similar statute or common law. (c) Nothing contained in this Section 5.10 shall limit the liability of any Borrower to pay Loans made directly or indirectly to that Borrower (including Loans advanced to any other Borrower and then re-loaned or otherwise transferred to, or for the benefit of, such Borrower), LC Obligations relating to Letters of Credit issued to support such Borrower’s business, and all accrued interest, fees, expenses and other related Obligations with respect thereto, for which such Borrower shall be primarily liable for all purposes hereunder. Agent and Lenders shall have the right, at any time in their discretion, to condition Loans and Letters of Credit upon a separate calculation of borrowing availability for each Borrower and to restrict the disbursement and use of such Loans and Letters of Credit to such Borrower. (d) Each Obligor that is a Qualified ECP when its guaranty of or grant of Lien as security for a Swap Obligation becomes effective hereby jointly and severally, absolutely, unconditionally and irrevocably undertakes to provide funds or other support to each Specified Obligor with respect to such Swap Obligation as may be needed by such Specified Obligor from time to time to honor all of its obligations under the Loan Documents in respect of such Swap Obligation (but, in each case, only up to the maximum amount of such liability that can be hereby incurred without rendering such Qualified ECP's obligations and undertakings under this Section 5.10 voidable under any applicable fraudulent transfer or conveyance act). The obligations and undertakings of each Qualified ECP under this Section shall remain in full force and effect until Full Payment of all Obligations. Each Obligor intends this Section to constitute, and this Section shall be deemed to constitute, a guarantee of the obligations of, and a “keepwell, support or other agreement” for the benefit of, each Obligor for all purposes of the Commodity Exchange Act. 5.10.4. Joint Enterprise. Each Borrower has requested that Agent and Lenders make this credit facility available to Borrowers on a combined basis, in order to finance Borrowers’ business most efficiently and economically. Borrowers’ business is a mutual and collective enterprise, and the successful operation of each Borrower is dependent upon the successful performance of the integrated group. Borrowers believe that consolidation of their

-61- credit facility will enhance the borrowing power of each Borrower and ease administration of the facility, all to their mutual advantage. Borrowers acknowledge that Agent’s and Lenders’ willingness to extend credit and to administer the Collateral on a combined basis hereunder is done solely as an accommodation to Borrowers and at Borrowers’ request. 5.10.5. Subordination. Each Borrower hereby subordinates any claims, including any rights at law or in equity to payment, subrogation, reimbursement, exoneration, contribution, indemnification or set off, that it may have at any time against any other Obligor, howsoever arising, to the Full Payment of all Obligations. SECTION 6. CONDITIONS PRECEDENT 6.1. Conditions Precedent to Initial Loans. In addition to the conditions set forth in Section 6.2, Lenders shall not be required to fund any requested Loan, issue any Letter of Credit, or otherwise extend credit to Borrowers hereunder, until the date (“Closing Date”) that each of the following conditions has been satisfied: (a) Each Loan Document shall have been duly executed and delivered to Agent by each of the signatories thereto, and each Obligor shall be in compliance with all terms thereof.

(d) Agent shall have received certificates, in form and substance satisfactory to it, from a knowledgeable Senior Officer of each Borrower certifying that, after giving effect to the initial Loans and transactions hereunder, (i) such Borrower is Solvent; (ii) no Default or Event of Default exists; (iii) the representations and warranties set forth in Section 9 are true and correct; and (iv) such Borrower has complied with all agreements and conditions to be satisfied by it under the Loan Documents.

Agent may conclusively rely on this certificate until it is otherwise notified by the applicable Obligor in writing.

-62- (f) Agent shall have received a written opinion of Akin Gump Xxxxxxx Xxxxx & Xxxx LLP, as well as any local counsel to Borrowers or Agent reasonably requested by Agent, in form and substance satisfactory to Agent. (g) Agent shall have received copies of the charter documents of each Obligor, certified by the Secretary of State or other appropriate official of such Obligor’s jurisdiction of organization. Agent shall have received good standing certificates for each Obligor, issued by the Secretary of State or other appropriate official of such Obligor’s jurisdiction of organization and each jurisdiction where such Obligor’s conduct of business or ownership of Property necessitates qualification. (h) No material adverse change in the financial condition of any Obligor or in the quality, quantity or value of any Collateral shall have occurred since December 31, 2012. (i) No action, suit, investigation or proceeding pending or, to the knowledge of any Borrower, threatened in any court or before any arbitrator or governmental authority that could reasonably be expected to have a Material Adverse Effect shall have occurred. (j) Borrowers shall have paid all fees and expenses to be paid to Agent and Lenders on the Closing Date. For purposes of determining compliance with the conditions specified in this Section 6.1, each Lender that has delivered a signature page to this Agreement shall be deemed to have consented to, approved or accepted, or to be satisfied with, each document or other matter required thereunder to be consented to or approved by or acceptable to a Lender or Agent unless Agent shall have received notice from such Lender prior to the proposed Closing Date specifying its objection thereto. 6.2. Conditions Precedent to All Credit Extensions. Agent, Issuing Bank and Lenders shall not be required to fund any Loans, arrange for issuance of any Letters of Credit or grant any other accommodation to or for the benefit of Borrowers, unless the following conditions are satisfied: (a) Subject to Section 10.1.13, no Default or Event of Default shall exist at the time of, or result from, such funding, issuance or grant; (b) Subject to Section 10.1.13, the representations and warranties of the Obligors in the Loan Documents shall be true and correct in all material respects on the date of, and upon giving effect to, such funding, issuance or grant (except for representations and warranties that expressly relate to an earlier date); (c) All conditions precedent in any other Loan Document shall be satisfied; (d) No event shall have occurred or circumstance exist that has or could reasonably be expected to have a Material Adverse Effect; and

-63- (e) With respect to issuance of a Letter of Credit, the LC Conditions shall be satisfied. Each request (or deemed request) by Borrowers for funding of a Loan, issuance of a Letter of Credit or grant of an accommodation shall constitute a representation by Borrowers that the foregoing conditions are satisfied on the date of such request and on the date of such funding, issuance or grant. As an additional condition to any funding, issuance or grant, Agent shall have received such other information, documents, instruments and agreements as it deems appropriate in connection therewith. SECTION 7. COLLATERAL 7.1. Grant of Security Interest. To secure the prompt payment and performance of all Obligations, each Obligor hereby grants to Agent, for the benefit of Secured Parties, a continuing security interest in and Lien upon all Property of such Obligor, including all of the following Property, whether now owned or hereafter acquired, and wherever located: (a) all Accounts; (b) all Chattel Paper, including electronic chattel paper; (c) all Commercial Tort Claims, including those shown on Schedule 9.1.16; (d) all Commodities Accounts, Deposit Accounts and Securities Accounts, including all cash, checks and other evidences of payment, marketable securities, securities entitlements, financial assets and other funds or Property held in or on deposit in any of the foregoing, in each case, to the extent any of the proceeds of Collateral are deposited therein; (e) all Documents; (f) all General Intangibles, including Intellectual Property; (g) all Goods, including Inventory (including As-Extracted Collateral), Equipment (including all Trucks and Machinery), and Fixtures; (h) all Instruments; (i) all Investment Property; (j) all Letter-of-Credit Rights; (k) all Supporting Obligations; (l) all As-Extracted Collateral; (m) all monies, whether or not in the possession or under the control of Agent, a Lender, or a bailee or Affiliate of Agent or a Lender, including any Cash Collateral;

-64- (n) all accessions to, substitutions for, and all replacements, products, and cash and non-cash proceeds of the foregoing, including proceeds of and unearned premiums with respect to insurance policies, and claims against any Person for loss, damage or destruction of any Collateral; and (o) all books and records (including customer lists, files, correspondence, tapes, computer programs, print-outs and computer records) pertaining to the foregoing. Notwithstanding the foregoing or any other provision of this Agreement or any other Loan Document, “Collateral” shall not include any Excluded Property, in each case only for so long as such item of Property continues to constitute Excluded Property, and thereafter shall constitute Collateral. The security interests and Liens granted in the Collateral are given in renewal, confirmation, extension and modification, but not in extinguishment, of the security interests and Liens previously granted in the Collateral pursuant to the Initial Loan Agreement (as defined in the Initial Loan Agreement) and the Initial Loan Agreement; such prior security interests and Liens are not extinguished hereby; and the making, perfection and priority of such prior security interests and Liens shall continue in full force and effect. 7.2. Liens on Deposit Accounts, Securities Accounts and Commodity Accounts; Cash Collateral. 7.2.1. Deposit Accounts, Securities Accounts and Commodity Accounts. To further secure the prompt payment and performance of all Obligations, each Obligor hereby grants to Agent a continuing security interest in and Lien upon all amounts credited to any Deposit Account (including any sums in any blocked or lockbox accounts or in any accounts into which such sums are swept) and all amounts credited to, and all financial assets and other funds or Property held in, any Securities Account and/or Commodities Account of such Obligor. Each Obligor hereby authorizes and directs each bank or other depository, securities intermediary or commodities intermediary, as applicable, to deliver to Agent, upon request, all balances in any Deposit Account maintained by such Obligor (other than Excluded Deposit Accounts) and all Investment Property, funds, commodity contracts and other Property credited to or held in any Securities Account or Commodity Accounts, as applicable (other than Excluded Securities and Commodities Accounts), without inquiry into the authority or right of Agent to make such request. 7.2.2. Cash Collateral. Cash Collateral may be invested, at Agent’s discretion (and with the consent of Obligors, as long as no Event of Default exists), but Agent shall have no duty to do so, regardless of any agreement or course of dealing with any Obligor, and shall have no responsibility for any investment or loss. Each Obligor hereby grants to Agent, as security for the Obligations, a security interest in all Cash Collateral held from time to time and all proceeds thereof, whether held in a Cash Collateral Account or otherwise. Agent may apply Cash Collateral to the payment of Obligations as they become due, in such order as Agent may elect. Each Cash Collateral Account and all Cash Collateral shall be under the sole dominion and control of Agent, and no Obligor or other Person shall have any right to any Cash Collateral, until Full Payment of all Obligations.

-65- 7.3. Real Estate Collateral. 7.3.1. [Reserved]. 7.3.2. Collateral Assignment of Leases. To further secure the prompt payment and performance of all Obligations, each Obligor hereby transfers and assigns to Agent all of such Obligor’s right, title and interest in, to and under all now or hereafter existing leases of real Property to which such Obligor is a party, whether as lessor or lessee, and all extensions, renewals, modifications and proceeds thereof. 7.4. Other Collateral. 7.4.1. Commercial Tort Claims. Borrowers shall promptly notify Agent in writing if any Obligor has a Commercial Tort Claim (other than, as long as no Default or Event of Default exists, a Commercial Tort Claim for less than $500,000), shall promptly amend Schedule 9.1.16 to include such claim, and shall take such actions as Agent reasonably deems appropriate to subject such claim to a duly perfected, first priority (or second priority, to the extent such Property is Senior Notes Priority Collateral) Lien in favor of Agent. 7.4.2. Certain After-Acquired Collateral. Borrowers shall promptly notify Agent in writing if, after the Closing Date, any Obligor obtains any interest in any Collateral consisting of Commodity Accounts, Deposit Accounts, Securities Accounts, Chattel Paper, Documents, Instruments, Intellectual Property, Investment Property or Letter-of-Credit Rights, in each case with a nominal value in excess of $100,000 and, upon Agent’s request, shall promptly take such actions as Agent deems appropriate to effect Agent’s duly perfected, first priority (or second priority, to the extent such Property is Senior Notes Priority Collateral) Lien upon such Collateral, including obtaining any appropriate possession, control agreement or Lien Waiver. If any Collateral is in the possession of a third party, at Agent’s request, Borrowers shall obtain an acknowledgment that such third party holds the Collateral for the benefit of Agent. 7.5. No Assumption of Liability. The Lien on Collateral granted hereunder is given as security only and shall not subject Agent or any Lender to, or in any way modify, any obligation or liability of Obligors relating to any Collateral. In no event shall the grant of any Lien under any Loan Document secure an Excluded Swap Obligation of the granting Obligor. 7.6. Further Assurances. All Liens granted to Agent under the Loan Documents are for the benefit of Secured Parties. Promptly upon request, Borrowers shall deliver such instruments and agreements, and shall take such actions, as Agent deems appropriate under Applicable Law to evidence or perfect its Lien on any Collateral, or otherwise to give effect to the intent of this Agreement. Each Obligor authorizes Agent to file any financing statement that describes the Collateral as “all assets” or “all personal property” of such Obligor, or words to similar effect, and ratifies any action taken by Agent before the Closing Date to effect or perfect its Lien on any Collateral. 7.7. Additional Borrowers. Borrower Agent may designate any Subsidiary as a Borrower under this Agreement and the other Loan Documents upon satisfaction of each of the following conditions, provided that such Subsidiary owns Eligible Accounts, Eligible Inventory, Eligible Trucks or, after the occurrence of the Machinery Qualifying Date, Eligible Machinery:

-66- (a) Borrower Agent shall have delivered to the Agent a written notice requesting that such Subsidiary be designated as a new Borrower. (b) The Agent shall have received a duly executed supplement to this Agreement and any other applicable Loan Documents joining such Subsidiary as a Borrower hereunder (such supplement to be in form and substance reasonably satisfactory to the Agent) and such other documents or agreements as Agent may request in its Permitted Discretion. (c) Such Subsidiary shall deliver to the Agent such documents and certificates referred to in Section 6.1(e) as may be reasonably requested by the Agent (it being agreed by US Concrete that, if the designation of such Subsidiary as a Borrower obligates the Agent or any Lender to comply with “know your customer” or similar identification procedures in circumstances where the necessary information is not already available to it, US Concrete shall, promptly upon the request of the Agent or any Lender, supply such documentation and other evidence as is reasonably requested by the Agent or any Lender in order for the Agent or such Lender to carry out, and be satisfied it has complied with the results of, all necessary “know your customer” or other similar checks under all Applicable Law). (d) If not previously granted to the Agent under this Agreement, as so supplemented, and the Security Documents, such Subsidiary shall grant a security interest in all Collateral owned by such Subsidiary by delivering to the Agent a duly executed supplement to each applicable Security Document or such other documents as the Agent shall reasonably deem appropriate for such purpose. SECTION 8. COLLATERAL ADMINISTRATION 8.1. Borrowing Base Certificates. By the 20th day of each month (or on the succeeding Business Day, if the applicable day is not a Business Day), Borrowers shall deliver to Agent (and Agent shall promptly deliver same to Lenders) a Borrowing Base Certificate prepared as of the close of business of the previous month, and during any Trigger Period Borrowers shall also deliver to Agent (and Agent shall promptly deliver same to Lenders) a Borrowing Base Certificate on a weekly basis, and in no event later than the 5th day of each week, prepared as of the close of the last day of the preceding week; provided, however, that during any period when an Event of Default exists, Borrower shall deliver a Borrowing Base as frequently as shall be requested by Agent. All calculations of Availability in any Borrowing Base Certificate shall originally be made by Borrowers and certified by a Senior Officer, provided that Agent may from time to time review and, in its Permitted Discretion, after Required Reserve Notice (provided that in no event shall such a Required Reserve Notice be required prior to or in connection with denying a request for a Revolver Loan due to insufficient Availability resulting from an adjustment in the calculation of Availability as contemplated by this Section), adjust any such calculation (a) to reflect its reasonable estimate of declines in value of any Collateral, due to collections received in the Dominion Account or otherwise; (b) to adjust advance rates to reflect changes in dilution, quality, mix and other factors affecting Collateral; and (c) to the extent the calculation is not made in accordance with this Agreement or does not accurately reflect the Availability Reserve, but in each case without duplication of (i) factors taken into consideration in determining eligibility of the relevant Accounts, Inventory, Trucks and Machinery and (ii) factors taken into consideration in determining the Availability Reserve.

-67- 8.2. Administration of Accounts. 8.2.1. Records and Schedules of Accounts. Each Borrower shall keep accurate and complete records of its Accounts, including all payments and collections thereon, and shall submit to Agent sales, collection, reconciliation and other reports in form satisfactory to Agent in its Permitted Discretion, on such periodic basis as Agent may request in its Permitted Discretion. Each Borrower shall also provide to Agent, on or before the 20th day of each month, a detailed aged trial balance of all Accounts as of the end of the preceding month, specifying each Account’s Account Debtor name and amount, invoice date and due date, showing any and such other information as Agent may request from time to time in its Permitted Discretion. If Accounts in an aggregate face amount of $1,000,000 or more cease to be Eligible Accounts, Borrowers shall notify Agent of such occurrence promptly (and in any event within one Business Day) after any Borrower has knowledge thereof. 8.2.2. Taxes. If an Account of any Borrower includes a charge for any Taxes, Agent is authorized, in its Permitted Discretion and after Required Reserve Notice to the Borrower, to pay the amount thereof to the proper taxing authority for the account of such Borrower and to charge Borrowers therefor; provided, however, that neither Agent nor Lenders shall be liable for any Taxes that may be due from Borrowers or with respect to any Collateral. 8.2.3. Account Verification. Whether or not a Default or Event of Default exists, Agent shall have the right at any time, in the name of Agent, any designee of Agent or any Borrower, to verify the validity, amount or any other matter relating to any Accounts of Borrowers by mail, telephone or otherwise. Prior to conducting any such verification, Agent shall provide reasonable prior notice (as determined by Agent in its Permitted Discretion) thereof to Borrower Agent, unless a Default exists or Agent determines that not providing such notice is appropriate to protect the interests of the Lenders. Borrowers shall cooperate fully with Agent in an effort to facilitate and promptly conclude any such verification process. 8.2.4. Maintenance of Dominion Account. Borrowers shall maintain Dominion Accounts pursuant to lockbox or other arrangements acceptable to Agent in its Permitted Discretion. Borrowers shall obtain an agreement (in form and substance satisfactory to Agent in its Permitted Discretion) from each lockbox servicer and Dominion Account bank, establishing Agent’s control over and Lien in the lockbox or Dominion Account, which may be exercised by Agent during any FCCR Trigger Period, requiring immediate deposit of all remittances received in the lockbox to a Dominion Account, and waiving offset rights of such servicer or bank, except for customary administrative charges. If a Dominion Account is not maintained with Bank of America, Agent may, during any FCCR Trigger Period, require immediate transfer of all funds in such account to a Dominion Account maintained with Bank of America. Agent and Lenders assume no responsibility to Borrowers for any lockbox arrangement or Dominion Account, including any claim of accord and satisfaction or release with respect to any Payment Items accepted by any bank. 8.2.5. Proceeds of Collateral. Borrowers shall request in writing and otherwise take all necessary steps to ensure that all payments on Accounts or otherwise relating to Collateral are made directly to a Dominion Account (or a lockbox relating to a Dominion Account). If any Borrower or Subsidiary receives cash or Payment Items with respect to any Collateral, it shall hold same in trust for Agent and promptly (not later than the next Business Day) deposit same into a Dominion Account.

-68- 8.3. Administration of Inventory. 8.3.1. Records and Reports of Inventory. Each Borrower shall keep accurate and complete records of its Inventory, including costs and daily withdrawals and additions, and shall submit to Agent inventory and reconciliation reports in form satisfactory to Agent, on such periodic basis as Agent may request in its Permitted Discretion. Each Borrower shall conduct a physical inventory at least once per calendar year (and on a more frequent basis if requested by Agent when an Event of Default exists) and periodic cycle counts consistent with historical practices, and, upon the request of Agent in its Permitted Discretion, shall provide to Agent a report based on each such inventory and count promptly upon completion thereof, together with such supporting information as Agent may request in its Permitted Discretion. Agent may participate in and observe each physical count at its own expense (unless an Event of Default exists, then at the Borrowers’ sole expense). 8.3.2. Returns of Inventory. No Borrower shall return any Inventory to a supplier, vendor or other Person, whether for cash, credit or otherwise, unless (a) such return is in the Ordinary Course of Business; (b) no Default, Event of Default or Overadvance exists or would result therefrom; (c) Agent is promptly notified if the aggregate Value of all Inventory returned in any month exceeds $1,000,000; and (d) any payment received by a Borrower for a return is promptly remitted to Agent for application to the Obligations. 8.3.3. Acquisition, Sale and Maintenance. Other than Inventory for chemical admixtures utilized to manufacture ready-mix concrete (“Permitted Consignment Inventory”), no Borrower shall acquire or accept any Inventory on consignment or approval, and shall take all steps to assure that all Inventory is produced in accordance with Applicable Law, including the FLSA. All Permitted Consignment Inventory shall be kept in separate containers, segregated from all other Inventory of the Obligors. Permitted Consignment Inventory shall in no event constitute Eligible Inventory. No Borrower shall sell any Inventory on consignment or approval or any other basis under which the customer may return or require a Borrower to repurchase such Inventory. Borrowers shall use, store and maintain all Inventory with reasonable care and caution, in accordance with applicable standards of any insurance and in conformity with all Applicable Law in all material respects, and shall make current rent payments (within applicable grace periods provided for in leases) at all locations where any Collateral is located. 8.4. Administration of Equipment. 8.4.1. Records and Schedules of Equipment. Each Borrower shall keep accurate and complete records of its Equipment, including kind, quality, quantity, cost, acquisitions and dispositions thereof, and shall submit to Agent, on such periodic basis as Agent may request, in its Permitted Discretion, a current schedule thereof, in form satisfactory to Agent. Promptly upon request, Borrowers shall deliver to Agent evidence of their ownership or interests in any Trucks and Machinery not constituting Excluded Trucks or Excluded Machinery (or, (i) in the case of any Trucks or Machinery the certificates of title for which are in the possession of the applicable Governmental Authority for lien recordation purposes, copies thereof, or (ii) in the case of any Truck or Machinery, the ownership of which is evidenced by an electronic title (ELT) in the records of the applicable Governmental Authority (in lieu of a physical certificate of title), a copy of the notification with respect to such notation received from such Governmental Authority, or (iii) in the case of any newly acquired Truck or Machinery in respect of which an application for a certificate of title has been filed with the applicable

-69- Governmental Authority but such certificate of title has not yet been issued, a copy of such application and the receipt therefor issued by such Governmental Authority).

Agent hereby agrees that self-insurance policies in effect on the Closing Date meet the foregoing insurance requirements as to the type of insurance covered by such self-insurance. From time to time upon request, Borrowers shall deliver to Agent the originals or certified copies of its insurance policies and updated flood plain searches. Unless Agent shall agree otherwise, each policy shall include satisfactory endorsements (i) showing Agent as loss payee; (ii) requiring 30 days prior written notice to Agent in the event of cancellation of the policy for any reason whatsoever; and (iii) specifying that the interest of Agent shall not be impaired or invalidated by any act or neglect of any Borrower or the owner of the Property, nor by the occupation of the premises for purposes more hazardous than are permitted by the policy. If any Borrower fails to provide and pay for any insurance, Agent may, at its option, but shall not be required to, procure the insurance and charge Borrowers therefor. Each Borrower agrees to deliver to Agent, promptly as rendered, copies of all reports made to insurance companies.

Agent shall not be liable or responsible in any way for the safekeeping of any Collateral, for any loss or damage thereto (except for reasonable care in its custody while Collateral is in Agent’s actual possession), for any diminution in the value thereof, or for any act or default of any warehouseman, carrier, forwarding agency or other Person whatsoever, but the same shall be at Borrowers’ sole risk. 8.6.4.

-92- diligence, presentment, demand, protest or notice of any kind, all of which are hereby waived by Borrowers to the fullest extent permitted by law; (b) terminate, reduce or condition any Commitment, or make any adjustment to the Borrowing Base; provided, Agent may not require Issuing Bank or any Lender to fund a Loan or issue a Letter of Credit during the continuance of an Event of Default or otherwise take action pursuant to this clause (b) that would require a Lender’s consent under Section 15.1.1 unless such requisite consents have been obtained; (c) require Obligors to Cash Collateralize LC Obligations, Secured Bank Product Obligations and other Obligations that are contingent or not yet due and payable, and, if Obligors fail promptly to deposit such Cash Collateral, Agent may (and shall upon the direction of Required Lenders) advance the required Cash Collateral as Revolver Loans (whether or not an Overadvance exists or is created thereby, or the conditions in Section 6 are satisfied); and (d) exercise any other rights or remedies afforded under any agreement, by law, at equity or otherwise, including the rights and remedies of a secured party under the UCC.

Each Obligor agrees that 10 days’ notice of any proposed sale or other disposition of Collateral by Agent shall be reasonable, and that any sale conducted on the internet or to a licensor of Intellectual Property shall be commercially reasonable. Agent may conduct sales on any Obligor’s premises, without charge, and any sale may be adjourned from time to time in accordance with Applicable Law. Agent shall have the right to sell, lease or otherwise dispose of any Collateral for cash, credit or any combination thereof, and Agent may purchase any Collateral at public or, if permitted by law, private sale and, in lieu of actual payment of the purchase price, may credit bid and set off the amount of such price against the Obligations. 11.3. License. Agent is hereby granted an irrevocable, non-exclusive license or other right, exercisable at any time an Event of Default exists, to use, license or sub-license (without payment of royalty or other compensation to any Person) any or all Intellectual Property of Obligors, computer hardware and software, trade secrets, brochures, customer lists, promotional and advertising materials, labels, packaging materials and other Property, in advertising for sale, marketing, selling, collecting, completing manufacture of, or otherwise exercising any rights or remedies with respect to, any Collateral. Each Obligor’s rights and interests under Intellectual Property shall inure to Agent’s benefit. 11.4. Setoff. At any time during an Event of Default, Agent, Issuing Bank, Lenders, and any of their Affiliates are authorized, to the fullest extent permitted by Applicable Law, to set off and apply any and all deposits (general or special, time or demand, provisional or final, in whatever currency, but excluding deposits held by Obligors in a fiduciary capacity) at any time held and other obligations (in whatever currency) at any time owing by Agent, Issuing Bank,

-93- such Lender or such Affiliate to or for the credit or the account of an Obligor against any Obligations, irrespective of whether or not Agent, Issuing Bank, such Lender or such Affiliate shall have made any demand under this Agreement or any other Loan Document and although such Obligations may be contingent or unmatured or are owed to a branch or office of Agent, Issuing Bank, such Lender or such Affiliate different from the branch or office holding such deposit or obligated on such indebtedness. The rights of Agent, Issuing Bank, each Lender and each such Affiliate under this Section are in addition to other rights and remedies (including other rights of setoff) that such Person may have. 11.5. Remedies Cumulative; No Waiver. 11.5.1. Cumulative Rights. All agreements, warranties, guaranties, indemnities and other undertakings of Obligors under the Loan Documents are cumulative and not in derogation of each other. The rights and remedies of Agent and Lenders are cumulative, may be exercised at any time and from time to time, concurrently or in any order, and are not exclusive of any other rights or remedies available by agreement, by law, at equity or otherwise. All such rights and remedies shall continue in full force and effect until Full Payment of all Obligations. 11.5.2. Waivers. No waiver or course of dealing shall be established by (a) the failure or delay of Agent or any Lender to require strict performance by Obligors with any terms of the Loan Documents, or to exercise any rights or remedies with respect to Collateral or otherwise; (b) the making of any Loan or issuance of any Letter of Credit during a Default, Event of Default or other failure to satisfy any conditions precedent; or (c) acceptance by Agent or any Lender of any payment or performance by an Obligor under any Loan Documents in a manner other than that specified therein. It is expressly acknowledged by Obligors that any failure to satisfy a financial covenant on a measurement date shall not be cured or remedied by satisfaction of such covenant on a subsequent date. SECTION 12. AGENT 12.1. Appointment, Authority and Duties of Agent. 12.1.1. Appointment and Authority. Each Secured Party appoints and designates Bank of America as Agent under all Loan Documents. Agent may, and each Secured Party authorizes Agent to, enter into all Loan Documents to which Agent is intended to be a party and accept all Security Documents, for the benefit of Secured Parties. Any action taken by Agent in accordance with the provisions of the Loan Documents, and the exercise by Agent of any rights or remedies set forth therein, together with all other powers reasonably incidental thereto, shall be authorized by and binding upon all Secured Parties. Without limiting the generality of the foregoing, Agent shall have the sole and exclusive authority to (a) act as the disbursing and collecting agent for Lenders with respect to all payments and collections arising in connection with the Loan Documents; (b) execute and deliver as Agent each Loan Document, including any intercreditor or subordination agreement, and accept delivery of each Loan Document; (c) act as collateral agent for Secured Parties for purposes of perfecting and administering Liens under the Loan Documents, and for all other purposes stated therein; (d) manage, supervise or otherwise deal with Collateral; and (e) take any Enforcement Action or otherwise exercise any rights or remedies with respect to any Collateral or under any Loan Documents, Applicable Law or otherwise. The duties of Agent are ministerial and administrative in nature only, and Agent shall not have a fiduciary relationship with any Secured

-94- Party, Participant or other Person, by reason of any Loan Document or any transaction relating thereto. Agent alone shall be authorized to determine whether any Account or Inventory constitutes an Eligible Account or Eligible Inventory, whether any Trucks or Machinery constitutes Eligible Trucks or Eligible Machinery, whether to impose or release any reserve, or whether any conditions to funding or to issuance of a Letter of Credit have been satisfied, which determinations and judgments, if exercised in good faith, shall exonerate Agent from liability to any Secured Party or other Person for any error in judgment. 12.1.2. Duties. Agent shall not have any duties except those expressly set forth in the Loan Documents. The conferral upon Agent of any right shall not imply a duty to exercise such right, unless instructed to do so by Lenders in accordance with this Agreement. 12.1.3. Agent Professionals. Agent may perform its duties through agents and employees. Agent may consult with and employ Agent Professionals, and shall be entitled to act upon, and shall be fully protected in any action taken in good faith reliance upon, any advice given by an Agent Professional. Agent shall not be responsible for the negligence or misconduct of any agents, employees or Agent Professionals selected by it with reasonable care. 12.1.4. Instructions of Required Lenders. The rights and remedies conferred upon Agent under the Loan Documents may be exercised without the necessity of joinder of any other party, unless required by Applicable Law. Agent may request instructions from Required Lenders or other Secured Parties with respect to any act (including the failure to act) in connection with any Loan Documents or Collateral, and may seek assurances to its satisfaction from Secured Parties of their indemnification obligations against Claims that could be incurred by Agent. Agent may refrain from any act until it has received such instructions or assurances, and shall not incur liability to any Person by reason of so refraining. Instructions of Required Lenders shall be binding upon all Secured Parties, and no Secured Party shall have any right of action whatsoever against Agent as a result of Agent acting or refraining from acting pursuant to instructions of Required Lenders. Notwithstanding the foregoing, instructions by and consent of specific parties shall be required to the extent provided in Section 15.1.1. In no event shall Agent be required to take any action that, in its opinion, is contrary to Applicable Law or any Loan Documents or could subject any Agent Indemnitee to personal liability. 12.2. Agreements Regarding Collateral and Borrower Materials. 12.2.1. Lien Releases; Care of Collateral. Secured Parties authorize Agent to release any Lien with respect to any Collateral (a) upon Full Payment of the outstanding Obligations and termination of all Commitments; (b) that is the subject of a disposition or Lien that Borrowers certify in writing is a Permitted Asset Disposition or a Permitted Lien entitled to priority over Agent’s Liens (and Agent may rely conclusively on any such certificate without further inquiry); (c) that does not constitute a material part of the Collateral; or (d) subject to Section 15.1, with the consent of Required Lenders. Secured Parties authorize Agent to subordinate its Liens to any Purchase Money Lien or other Lien entitled to priority hereunder. Agent shall have no obligation to assure that any Collateral exists or is owned by an Obligor, or is cared for, protected or insured, nor to assure that Agent’s Liens have been properly created, perfected or enforced, or are entitled to any particular priority, nor to exercise any duty of care with respect to any Collateral.

-95- 12.2.2. Possession of Collateral. Agent and Secured Parties appoint each Lender as agent (for the benefit of Secured Parties) for the purpose of perfecting Liens in any Collateral held or controlled by such Lender, to the extent such Liens are perfected by possession or control. If any Lender obtains possession or control of any Collateral, it shall notify Agent thereof and, promptly upon Agent’s request, deliver such Collateral to Agent or otherwise deal with it in accordance with Agent’s instructions. 12.2.3. Reports. Agent shall promptly provide to Lenders, when complete, any field audit, examination or appraisal report prepared for Agent with respect to any Obligor or Collateral (“Report”). Reports and other Borrower Materials may be made available to Lenders by providing access to them on the Platform, but Agent shall not be responsible for system failures or access issues that may occur from time to time. Each Lender agrees (a) that Reports are not intended to be comprehensive audits or examinations, and that Agent or any other Person performing an audit or examination will inspect only specific information regarding the Obligations or Collateral and will rely significantly upon Borrowers’ books, records and representations; (b) that Agent makes no representation or warranty as to the accuracy or completeness of any Borrower Materials and shall not be liable for any information contained in or omitted from any Borrower Materials, including any Report; and (c) to keep all Borrower Materials confidential and strictly for such Lender’s internal use, not to distribute any Report or other Borrower Materials (or the contents thereof) to any Person (except to such Lender’s Participants, attorneys and accountants), and to use all Borrower Materials solely for administration of the Obligations. Each Lender shall indemnify and hold harmless Agent and any other Person preparing a Report from any action such Lender may take as a result of or any conclusion it may draw from any Borrower Materials, as well as from any Claims arising as a direct or indirect result of Agent furnishing same to such Lender, via the Platform or otherwise. 12.3. Reliance By Agent. Agent shall be entitled to rely, and shall be fully protected in relying, upon any certification, notice or other communication (including those by telephone, telex, telegram, telecopy or e-mail) believed by it to be genuine and correct and to have been signed, sent or made by the proper Person. Agent shall have a reasonable and practicable amount of time to act upon any instruction, notice or other communication under any Loan Document, and shall not be liable for any delay in acting. 12.4. Action Upon Default. Agent shall not be deemed to have knowledge of any Default or Event of Default, or of any failure to satisfy any conditions in Section 6, unless it has received written notice from a Borrower or Required Lenders specifying the occurrence and nature thereof. If any Lender acquires knowledge of a Default, Event of Default or failure of such conditions, it shall promptly notify Agent and the other Lenders thereof in writing. Each Secured Party agrees that, except as otherwise provided in any Loan Documents or with the written consent of Agent and Required Lenders, it will not take any Enforcement Action, accelerate Obligations (other than Secured Bank Product Obligations), or exercise any right that it might otherwise have under Applicable Law to credit bid at foreclosure sales, UCC sales or other dispositions of Collateral, or to assert any rights relating to any Collateral. 12.5. Ratable Sharing. If any Lender obtains any payment or reduction of any Obligation, whether through set-off or otherwise, in excess of its share of such Obligation, determined on a Pro Rata basis or in accordance with Section 5.5.2, as applicable, such Lender shall forthwith purchase from Agent, Issuing Bank and the other Lenders such participations in the affected Obligation as are necessary to share the excess payment or reduction on a Pro Rata

-96- basis or in accordance with Section 5.5.2, as applicable. If any of such payment or reduction is thereafter recovered from the purchasing Lender, the purchase shall be rescinded and the purchase price restored to the extent of such recovery, but without interest. Notwithstanding the foregoing, if a Defaulting Lender obtains a payment or reduction of any Obligation, it shall immediately turn over the amount thereof to Agent for application under Section 4.2.2 and it shall provide a written statement to Agent describing the Obligation affected by such payment or reduction. No Lender shall set off against any Dominion Account without Agent’s prior consent. 12.6. Indemnification. EACH LENDER SHALL INDEMNIFY AND HOLD HARMLESS AGENT INDEMNITEES AND ISSUING BANK INDEMNITEES, TO THE EXTENT NOT REIMBURSED BY OBLIGORS, ON A PRO RATA BASIS, AGAINST ALL CLAIMS THAT MAY BE INCURRED BY OR ASSERTED AGAINST ANY SUCH INDEMNITEE, PROVIDED THAT ANY CLAIM AGAINST AN AGENT INDEMNITEE RELATES TO OR ARISES FROM ITS ACTING AS OR FOR AGENT (IN THE CAPACITY OF AGENT). In no event shall any Lender have any obligation hereunder to indemnify or hold harmless an Agent Indemnitee with respect to a Claim that is determined in a final, non- appealable judgment by a court of competent jurisdiction to result from the gross negligence or willful misconduct of such Agent Indemnitee. In Agent’s Permitted Discretion, it may reserve for any Claims made against an Agent Indemnitee or Issuing Bank Indemnitee, and may satisfy any judgment, order or settlement relating thereto, from proceeds of Collateral prior to making any distribution of Collateral proceeds to Secured Parties. If Agent is sued by any receiver, trustee or other Person for any alleged preference or fraudulent transfer, then any monies paid by Agent in settlement or satisfaction of such proceeding, together with all interest, costs and expenses (including attorneys’ fees) incurred in the defense of same, shall be promptly reimbursed to Agent by each Lender to the extent of its Pro Rata share. 12.7. Limitation on Responsibilities of Agent. Agent shall not be liable to any Secured Party for any action taken or omitted to be taken under the Loan Documents, except for losses directly and solely caused by Agent’s gross negligence or willful misconduct. Agent does not assume any responsibility for any failure or delay in performance or any breach by any Obligor, Lender or other Secured Party of any obligations under the Loan Documents. Agent does not make any express or implied representation, warranty or guarantee to Secured Parties with respect to any Obligations, Collateral, Loan Documents or Obligor. No Agent Indemnitee shall be responsible to Secured Parties for any recitals, statements, information, representations or warranties contained in any Loan Documents or Borrower Materials; the execution, validity, genuineness, effectiveness or enforceability of any Loan Documents; the genuineness, enforceability, collectibility, value, sufficiency, location or existence of any Collateral, or the validity, extent, perfection or priority of any Lien therein; the validity, enforceability or collectibility of any Obligations; or the assets, liabilities, financial condition, results of operations, business, creditworthiness or legal status of any Obligor or Account Debtor. No Agent Indemnitee shall have any obligation to any Secured Party to ascertain or inquire into the existence of any Default or Event of Default, the observance by any Obligor of any terms of the Loan Documents, or the satisfaction of any conditions precedent contained in any Loan Documents. 12.8. Successor Agent and Co-Agents. 12.8.1. Resignation; Successor Agent. Subject to the appointment and acceptance of a successor Agent as provided below, Agent may resign at any time by giving at

-97- least 30 days written notice thereof to Lenders and Borrowers. Upon receipt of such notice, Required Lenders shall have the right to appoint a successor Agent which shall be (a) a Lender or an Affiliate of a Lender; or (b) a financial institution reasonably acceptable to Required Lenders and (provided no Default or Event of Default exists) Borrowers. If no successor agent is appointed prior to the effective date of Agent’s resignation, then Agent may appoint a successor agent that is a financial institution acceptable to it, which shall be a Lender unless no Lender accepts the role. Upon acceptance by a successor Agent of its appointment hereunder, such successor Agent shall thereupon succeed to and become vested with all the powers and duties of the retiring Agent without further act, and the retiring Agent shall be discharged from its duties and obligations hereunder but shall continue to have the benefits of the indemnification set forth in Sections 12.6 and 15.2. Notwithstanding any Agent’s resignation, the provisions of this Section 12 shall continue in effect for its benefit with respect to any actions taken or omitted to be taken by it while Agent. Any successor to Bank of America by merger or acquisition of stock or this loan shall continue to be Agent hereunder without further act on the part of any Secured Party or Obligor. 12.8.2. Co-Collateral Agent. If necessary or appropriate under Applicable Law, Agent may appoint a Person to serve as a co-collateral agent or separate collateral agent under any Loan Document. Each right and remedy intended to be available to Agent under the Loan Document shall also be vested in such agent. Secured Parties shall execute and deliver any instrument or agreement that Agent may request to effect such appointment. If the agent shall die, dissolve, become incapable of acting, resign or be removed, then all the rights and remedies of such agent, to the extent permitted by Applicable Law, shall vest in and be exercised by Agent until appointment of a new agent. 12.9. Due Diligence and Non-Reliance. Each Lender acknowledges and agrees that it has, independently and without reliance upon Agent or any other Lenders, and based upon such documents, information and analyses as it has deemed appropriate, made its own credit analysis of each Obligor and its own decision to enter into this Agreement and to fund Loans and participate in LC Obligations hereunder. Each Secured Party has made such inquiries as it feels necessary concerning the Loan Documents, Collateral and Obligors. Each Secured Party acknowledges and agrees that the other Secured Parties have made no representations or warranties concerning any Obligor, any Collateral or the legality, validity, sufficiency or enforceability of any Loan Documents or Obligations. Each Secured Party will, independently and without reliance upon any other Secured Party, and based upon such financial statements, documents and information as it deems appropriate at the time, continue to make and rely upon its own credit decisions in making Loans and participating in LC Obligations, and in taking or refraining from any action under any Loan Documents. Except for notices, reports and other information expressly requested by a Lender, Agent shall have no duty or responsibility to provide any Secured Party with any notices, reports or certificates furnished to Agent by any Obligor or any credit or other information concerning the affairs, financial condition, business or Properties of any Obligor (or any of its Affiliates) which may come into possession of Agent or its Affiliates. 12.10. Remittance of Payments and Collections. 12.10.1. Remittances Generally. All payments by any Lender to Agent shall be made by the time and on the day set forth in this Agreement, in immediately available funds. If no time for payment is specified or if payment is due on demand by Agent and request for

-98- payment is made by Agent by 11:00 a.m. on a Business Day, payment shall be made by Lender not later than 2:00 p.m. on such day, and if request is made after 11:00 a.m., then payment shall be made by 11:00 a.m. on the next Business Day. Payment by Agent to any Secured Party shall be made by wire transfer, in the type of funds received by Agent. Any such payment shall be subject to Agent’s right of offset for any amounts due from such payee under the Loan Documents. 12.10.2. Failure to Pay. If any Secured Party fails to pay any amount when due by it to Agent pursuant to the terms hereof, such amount shall bear interest, from the due date until paid in full, at the rate determined by Agent as customary for interbank compensation for two Business Days and thereafter at the Default Rate for Base Rate Revolver Loans. In no event shall Borrowers be entitled to receive credit for any interest paid by a Secured Party to Agent, nor shall any Defaulting Lender be entitled to interest on any amounts held by Agent pursuant to Section 4.2. 12.10.3. Recovery of Payments. If Agent pays an amount to a Secured Party in the expectation that a related payment will be received by Agent from an Obligor and such related payment is not received, then Agent may recover such amount from the Secured Party. If Agent determines that an amount received by it must be returned or paid to an Obligor or other Person pursuant to Applicable Law or otherwise, then, notwithstanding any other term of any Loan Document, Agent shall not be required to distribute such amount to any Secured Party. If any amounts received and applied by Agent to any Obligations are later required to be returned by Agent pursuant to Applicable Law, each Lender shall pay to Agent, on demand, such Lender’s Pro Rata share of the amounts required to be returned. 12.11. Individual Capacities. As a Lender, Bank of America shall have the same rights and remedies under the Loan Documents as any other Lender, and the terms “Lenders,” “Required Lenders” or any similar term shall include Bank of America in its capacity as a Lender. Agent, Lenders and their Affiliates may accept deposits from, lend money to, provide Bank Products to, act as financial or other advisor to, and generally engage in any kind of business with, Obligors and their Affiliates, as if they were not Agent or Lenders hereunder, without any duty to account therefor to any Secured Party. In their individual capacities, Agent, Lenders and their Affiliates may receive information regarding Obligors, their Affiliates and their Account Debtors (including information subject to confidentiality obligations), and shall have no obligation to provide such information to any Secured Party. 12.12. Titles. Each Lender, other than Bank of America, that is designated (on the cover page of this Agreement or otherwise) by Bank of America as an “Arranger,” “Bookrunner” or “Agent” of any type shall have no right, power or duty under any Loan Documents other than those applicable to all Lenders, and shall in no event have any fiduciary duty to any Secured Party. 12.13. Bank Product Providers. Each Secured Bank Product Provider, by delivery of a notice to Agent of a Bank Product, agrees to be bound by Section 5.5 and this Section 12. Each Secured Bank Product Provider shall indemnify and hold harmless Agent Indemnitees, to the extent not reimbursed by Obligors, against all Claims that may be incurred by or asserted against any Agent Indemnitee in connection with such provider’s Secured Bank Product Obligations.

-99- 12.14. No Third Party Beneficiaries. This Section 12 is an agreement solely among Secured Parties and Agent, and shall survive Full Payment of the Obligations. Other than Section 12.8.1(b), this Section 12 does not confer any rights or benefits upon Borrowers or any other Person. As between Borrowers and Agent, any action that Agent may take under any Loan Documents or with respect to any Obligations shall be conclusively presumed to have been authorized and directed by Secured Parties. SECTION 13. BENEFIT OF AGREEMENT; ASSIGNMENTS 13.1. Successors and Assigns. This Agreement shall be binding upon and inure to the benefit of Obligors, Agent, Lenders, Secured Parties, and their respective successors and assigns, except that (a) no Obligor shall have the right to assign its rights or delegate its obligations under any Loan Documents (except in connection with a transaction permitted under Section 10.2.8); and (b) any assignment by a Lender must be made in compliance with Section 13.3. Agent may treat the Person which made any Loan as the owner thereof for all purposes until such Person makes an assignment in accordance with Section 13.3. Any authorization or consent of a Lender shall be conclusive and binding on any subsequent transferee or assignee of such Lender. 13.2. Participations. 13.2.1. Permitted Participants; Effect. Subject to Section 13.3.3, any Lender may sell to a financial institution (“Participant”) a participating interest in the rights and obligations of such Lender under any Loan Documents. Despite any sale by a Lender of participating interests to a Participant, such Lender’s obligations under the Loan Documents shall remain unchanged, it shall remain solely responsible to the other parties hereto for performance of such obligations, it shall remain the holder of its Loans and Commitments for all purposes, all amounts payable by Borrowers shall be determined as if it had not sold such participating interests, and Borrowers and Agent shall continue to deal solely and directly with such Lender in connection with the Loan Documents. Each Lender shall be solely responsible for notifying its Participants of any matters under the Loan Documents, and Agent and the other Lenders shall not have any obligation or liability to any such Participant. A Participant that would be a Foreign Lender if it were a Lender shall not be entitled to the benefits of Section 5.9 unless Borrowers agree otherwise in writing. 13.2.2. Voting Rights. Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, waiver or other modification of a Loan Document other than that which forgives principal, interest or fees, reduces the stated interest rate or fees payable with respect to any Loan or Commitment in which such Participant has an interest, postpones the Commitment Termination Date or any date fixed for any regularly scheduled payment of principal, interest or fees on such Loan or Commitment, or releases any Borrower, Guarantor or substantially all Collateral. 13.2.3. Benefit of Set-Off. Obligors agree that each Participant shall have a right of set-off in respect of its participating interest to the same extent as if such interest were owing directly to a Lender, and each Lender shall also retain the right of set-off with respect to any participating interests sold by it. By exercising any right of set-off, a Participant agrees to share with Lenders all amounts received through its set-off, in accordance with Section 12.5 as if such Participant were a Lender.

-100- 13.3. Assignments. 13.3.1. Permitted Assignments. A Lender may assign to an Eligible Assignee any of its rights and obligations under the Loan Documents, as long as (a) each assignment is of a constant, and not a varying, percentage of the transferor Lender’s rights and obligations under the Loan Documents and, in the case of a partial assignment, is in a minimum principal amount of $5,000,000 (unless otherwise agreed by Agent in its discretion) and integral multiples of $1,000,000 in excess of that amount; (b) except in the case of an assignment in whole of a Lender’s rights and obligations, the aggregate amount of the Commitments retained by the transferor Lender is at least $5,000,000 (unless otherwise agreed by Agent in its discretion); and (c) the parties to each such assignment shall execute and deliver to Agent, for its acceptance and recording, an Assignment and Acceptance. Nothing herein shall limit the right of a Lender to pledge or assign any rights under the Loan Documents to secure obligations of such Lender, including a pledge or assignment to a Federal Reserve Bank; provided, however, that no such pledge or assignment shall release the Lender from its obligations hereunder nor substitute the pledge or assignee for such Lender as a party hereto. 13.3.2. Effect; Effective Date. Upon delivery to Agent of an assignment notice in the form of Exhibit B and a processing fee of $3,500 (unless otherwise agreed by Agent in its discretion), the assignment shall become effective as specified in the notice, if it complies with this Section 13.3. From such effective date, the Eligible Assignee shall for all purposes be a Lender under the Loan Documents, and shall have all rights and obligations of a Lender thereunder. Upon consummation of an assignment, the transferor Lender, Agent and Borrowers shall make appropriate arrangements for issuance of replacement and/or new notes, if applicable. The transferee Lender shall comply with Section 5.9 and deliver, upon request, an administrative questionnaire satisfactory to Agent. 13.3.3. Certain Assignees. No assignment or participation may be made to an Obligor, Affiliate of an Obligor, Defaulting Lender or natural person. Any assignment by a Defaulting Lender shall be effective only upon payment by the Eligible Assignee or Defaulting Lender to Agent of an aggregate amount sufficient, upon distribution (through direct payment, purchases of participations or other compensating actions as Agent deems appropriate), to satisfy all funding and payment liabilities then owing by the Defaulting Lender hereunder. If an assignment by a Defaulting Lender shall become effective under Applicable Law for any reason without compliance with the foregoing sentence, then the assignee shall be deemed a Defaulting Lender for all purposes until such compliance occurs. 13.3.4. Register. Agent, acting as a non-fiduciary agent of Borrowers (solely for tax purposes), shall maintain (a) a copy of each Assignment and Acceptance delivered to it, and (b) a register for recordation of the names, addresses and Commitments of, and the Loans, interest and LC Obligations owing to, each Lender. Entries in the register shall be conclusive, absent manifest error, and Borrowers, Agent and Lenders shall treat each lender recorded in such register as a Lender for all purposes under the Loan Documents, notwithstanding any notice to the contrary. The register shall be available for inspection by Borrowers or any Lender, from time to time upon reasonable notice. 13.4. Replacement of Certain Lenders. If a Lender (a) fails to give its consent to any amendment, waiver or action for which consent of all Lenders was required and Required Lenders consented, or (b) is a Defaulting Lender, then, in addition to any other rights and

-101- remedies that any Person may have, Agent or Borrower Agent may, by notice to such Lender within 120 days after such event, require such Lender to assign all of its rights and obligations under the Loan Documents to Eligible Assignee(s), pursuant to appropriate Assignment and Acceptance(s), within 20 days after the notice. Agent is irrevocably appointed as attorney-in- fact to execute any such Assignment and Acceptance if the Lender fails to execute it. Such Lender shall be entitled to receive, in cash, concurrently with such assignment, all amounts owed to it under the Loan Documents through the date of assignment. SECTION 14. GUARANTY 14.1. Guaranty of the Obligations. Subject to the provisions of Section 14.2, Guarantors jointly and severally hereby irrevocably and unconditionally guaranty to Agent and Lenders the due and punctual payment in full of all Obligations (other than Excluded Swap Obligations) when the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code) (collectively, the “Guaranteed Obligations”). 14.2. Contribution by Guarantors. All Guarantors desire to allocate among themselves (collectively, the “Contributing Guarantors”), in a fair and equitable manner, their obligations arising under this Guaranty. Accordingly, in the event any payment or distribution is made on any date by a Guarantor (a “Funding Guarantor”) under this Guaranty such that its Aggregate Payments exceeds its Fair Share as of such date, such Funding Guarantor shall be entitled to a contribution from each of the other Contributing Guarantors in an amount sufficient to cause each Contributing Guarantor’s Aggregate Payments to equal its Fair Share as of such date. “Fair Share” means, with respect to a Contributing Guarantor as of any date of determination, an amount equal to (a) the ratio of (i) the Fair Share Contribution Amount with respect to such Contributing Guarantor, to (ii) the aggregate of the Fair Share Contribution Amounts with respect to all Contributing Guarantors multiplied by, (b) the aggregate amount paid or distributed on or before such date by all Funding Guarantors under this Guaranty in respect of the obligations Guaranteed. “Fair Share Contribution Amount” means, with respect to a Contributing Guarantor as of any date of determination, the maximum aggregate amount of the obligations of such Contributing Guarantor under this Guaranty that would not render its obligations hereunder subject to avoidance as a fraudulent transfer or conveyance under Section 548 of Title 11 of the United States Code or any comparable applicable provisions of state law; provided, solely for purposes of calculating the “Fair Share Contribution Amount” with respect to any Contributing Guarantor for purposes of this Section 14.2, any assets or liabilities of such Contributing Guarantor arising by virtue of any rights to subrogation, reimbursement or indemnification or any rights to or obligations of contribution hereunder shall not be considered as assets or liabilities of such Contributing Guarantor. “Aggregate Payments” means, with respect to a Contributing Guarantor as of any date of determination, an amount equal to (1) the aggregate amount of all payments and distributions made on or before such date by such Contributing Guarantor in respect of this Guaranty (including, without limitation, in respect of this Section 14.2), minus (2) the aggregate amount of all payments received on or before such date by such Contributing Guarantor from the other Contributing Guarantors as contributions under this Section 14.2. The amounts payable as contributions hereunder shall be determined as of the date on which the related payment or distribution is made by the applicable Funding Guarantor. The allocation among Contributing Guarantors of their obligations as set forth in this Section 14.2 shall not be construed in any way to limit the liability of any

-102- Contributing Guarantor hereunder. Each Guarantor is a third-party beneficiary to the contribution agreement set forth in this Section 14.2. 14.3. Payment by Guarantors. Subject to Section 14.2, Guarantors hereby jointly and severally agree, in furtherance of the foregoing and not in limitation of any other right which Lender may have at law or in equity against any Guarantor by virtue hereof, that upon the failure of any Borrower to pay any of the Guaranteed Obligations when and as the same shall become due, whether at stated maturity, by required prepayment, declaration, acceleration, demand or otherwise (including amounts that would become due but for the operation of the automatic stay under Section 362(a) of the Bankruptcy Code), Guarantors will upon demand pay, or cause to be paid, in cash, to Agent, for the benefit of itself and the Lenders, an amount equal to the sum of the unpaid principal amount of all Guaranteed Obligations then due as aforesaid, accrued and unpaid interest on such Guaranteed Obligations (including interest which, but for any Borrower’s becoming the subject of a case under the Bankruptcy Code, would have accrued on such Guaranteed Obligations, whether or not a claim is allowed against such Borrower for such interest in the related bankruptcy case) and all other Guaranteed Obligations then owed to Agent and Lenders as aforesaid. 14.4. Liability of Guarantors Absolute. Each Guarantor agrees that its obligations hereunder are irrevocable, absolute, independent and unconditional and shall not be affected by any circumstance which constitutes a legal or equitable discharge of a guarantor or surety other than payment in full of the Guaranteed Obligations. In furtherance of the foregoing and without limiting the generality thereof, each Guarantor agrees as follows: 14.4.1. this Guaranty is a guaranty of payment when due and not of collectability. This Guaranty is a primary obligation of each Guarantor and not merely a contract of surety; 14.4.2. Agent may enforce this Guaranty upon the occurrence of an Event of Default notwithstanding the existence of any dispute between any Borrower and Agent or any Lender with respect to the existence of such Event of Default; 14.4.3. the obligations of each Guarantor hereunder are independent of the obligations of Borrowers and the obligations of any other guarantor (including any other Guarantor) of the obligations of Borrowers, and a separate action or actions may be brought and prosecuted against such Guarantor whether or not any action is brought against any Borrower or any of such other guarantors and whether or not any Borrower is joined in any such action or actions; 14.4.4. payment by any Guarantor of a portion, but not all, of the Guaranteed Obligations shall in no way limit, affect, modify or abridge any Guarantor’s liability for any portion of the Guaranteed Obligations which has not been paid. Without limiting the generality of the foregoing, if Agent or any Lender is awarded a judgment in any suit brought to enforce any Guarantor’s covenant to pay a portion of the Guaranteed Obligations, such judgment shall not be deemed to release such Guarantor from its covenant to pay the portion of the Guaranteed Obligations that is not the subject of such suit, and such judgment shall not, except to the extent satisfied by such Guarantor, limit, affect, modify or abridge any other Guarantor’s liability hereunder in respect of the Guaranteed Obligations;

-103- 14.4.5. Agent and/or Lenders, upon such terms as they deem appropriate, without notice or demand and without affecting the validity or enforceability hereof or giving rise to any reduction, limitation, impairment, discharge or termination of any Guarantor’s liability hereunder, from time to time may (i) renew, extend, accelerate, increase the rate of interest on, or otherwise change the time, place, manner or terms of payment of the Guaranteed Obligations; (ii) settle, compromise, release or discharge, or accept or refuse any offer of performance with respect to, or substitutions for, the Guaranteed Obligations or any agreement relating thereto and/or subordinate the payment of the same to the payment of any other obligations; (iii) request and accept other guaranties of the Guaranteed Obligations and take and hold security for the payment hereof or the Guaranteed Obligations; (iv) release, surrender, exchange, substitute, compromise, settle, rescind, waive, alter, subordinate or modify, with or without consideration, any security for payment of the Guaranteed Obligations, any other guaranties of the Guaranteed Obligations, or any other obligation of any Person (including any other Guarantor) with respect to the Guaranteed Obligations; (v) enforce and apply any security now or hereafter held by or for the benefit of Agent for the benefit of itself and the Lenders in respect hereof or the Guaranteed Obligations and direct the order or manner of sale thereof, or exercise any other right or remedy that Agent may have against any such security, in each case as Agent in its discretion may determine consistent herewith or any applicable security agreement, including foreclosure on any such security pursuant to one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially reasonable, and even though such action operates to impair or extinguish any right of reimbursement or subrogation or other right or remedy of any Guarantor against any Borrower or any security for the Guaranteed Obligations; and (vi) exercise any other rights available to it under the Loan Documents; and 14.4.6. this Guaranty and the obligations of Guarantors hereunder shall be valid and enforceable and shall not be subject to any reduction, limitation, impairment, discharge or termination for any reason (other than payment in full of the Guaranteed Obligations), including the occurrence of any of the following, whether or not any Guarantor shall have had notice or knowledge of any of them: (i) any failure or omission to assert or enforce or agreement or election not to assert or enforce, or the stay or enjoining, by order of court, by operation of law or otherwise, of the exercise or enforcement of, any claim or demand or any right, power or remedy (whether arising under the Loan Documents, at law, in equity or otherwise) with respect to the Guaranteed Obligations or any agreement relating thereto, or with respect to any other guaranty of or security for the payment of the Guaranteed Obligations; (ii) any rescission, waiver, amendment or modification of, or any consent to departure from, any of the terms or provisions (including provisions relating to events of default) hereof, any of the other Loan Documents or any agreement or instrument executed pursuant thereto, or of any other guaranty or security for the Guaranteed Obligations, in each case whether or not in accordance with the terms hereof or such Loan Document, or any agreement relating to such other guaranty or security; (iii) the Guaranteed Obligations, or any agreement relating thereto, at any time being found to be illegal, invalid or unenforceable in any respect; (iv) the application of payments received from any source (other than payments received pursuant to the other Loan Documents or from the proceeds of any security for the Guaranteed Obligations, except to the extent such security also serves as collateral for indebtedness other than the Guaranteed Obligations) to the payment of indebtedness other than the Guaranteed Obligations, even though Agent or Lenders might have elected to apply such payment to any part or all of the Guaranteed Obligations; (v) Agent’s or Lenders’ consent to the change, reorganization or termination of the corporate structure or existence of US Concrete or any of its Subsidiaries and to any corresponding restructuring of the Guaranteed Obligations; (vi) any failure to perfect or continue perfection of a security interest in

-104- any collateral which secures any of the Guaranteed Obligations; (vii) any defenses, set-offs or counterclaims which any Borrower may allege or assert against Agent or any Lender in respect of the Guaranteed Obligations, including failure of consideration, breach of warranty, payment, statute of frauds, statute of limitations, accord and satisfaction and usury; and (viii) any other act or thing or omission, or delay to do any other act or thing, which may or might in any manner or to any extent vary the risk of any Guarantor as an Obligor in respect of the Guaranteed Obligations. 14.5. Waivers by Guarantors. Each Guarantor hereby waives, for the benefit of Agent and each Lender: (a) any right to require Agent or any Lender, as a condition of payment or performance by such Guarantor, to (i) proceed against any Borrower, any other guarantor (including any other Guarantor) of the Guaranteed Obligations or any other Person, (ii) proceed against or exhaust any security held from any Borrower, any such other guarantor or any other Person, (iii) proceed against or have resort to any balance of any Deposit Account, Securities Account or Commodities Account or credit on the books of Agent or any Lender in favor of any Borrower or any other Person, or (iv) pursue any other remedy in the power of Agent or any Lender whatsoever; (b) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of any Borrower or any other Guarantor including any defense based on or arising out of the lack of validity or the unenforceability of the Guaranteed Obligations or any agreement or instrument relating thereto or by reason of the cessation of the liability of any Borrower or any other Guarantor from any cause other than payment in full of the Guaranteed Obligations; (c) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (d) any defense based upon Agent’s or any Lender’s errors or omissions in the administration of the Guaranteed Obligations, except behavior which amounts to bad faith; (e) (i) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms hereof and any legal or equitable discharge of such Guarantor’s obligations hereunder, (ii) the benefit of any statute of limitations affecting such Guarantor’s liability hereunder or the enforcement hereof, (iii) any rights to set-offs, recoupments and counterclaims, and (iv) promptness, diligence and any requirement that Agent or any Lender protect, secure, perfect or insure any security interest or lien or any property subject thereto; (f) notices, demands, presentments, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance hereof, notices of default hereunder or any agreement or instrument related thereto, notices of any renewal, extension or modification of the Guaranteed Obligations or any agreement related thereto, notices of any extension of credit to Borrowers and notices of any of the matters referred to in Section 14.4 and any right to consent to any thereof; and (g) any defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms hereof other than Full Payment of the Obligations. 14.6. Guarantors’ Rights of Subrogation, Contribution, etc. Until the Guaranteed Obligations shall have been indefeasibly paid in full and the Commitments shall have terminated and all Letters of Credit shall have expired or been cancelled, each Guarantor hereby waives any claim, right or remedy, direct or indirect, that such Guarantor now has or may hereafter have against any Borrower or any other Guarantor or any of its assets in connection with this Guaranty or the performance by such Guarantor of its obligations hereunder, in each case whether such claim, right or remedy arises in equity, under contract, by statute, under common law or otherwise and including without limitation (a) any right of subrogation, reimbursement or indemnification that such Guarantor now has or may hereafter have against any Borrower with

-105- respect to the Guaranteed Obligations, (b) any right to enforce, or to participate in, any claim, right or remedy that Agent or any Lender now has or may hereafter have against any Borrower, and (c) any benefit of, and any right to participate in, any collateral or security now or hereafter held by Agent or any Lender. In addition, until the Guaranteed Obligations shall have been indefeasibly paid in full and the Commitment shall have terminated and all Letters of Credit shall have expired or been cancelled, each Guarantor shall withhold exercise of any right of contribution such Guarantor may have against any other guarantor (including any other Guarantor) of the Guaranteed Obligations, including, without limitation, any such right of contribution as contemplated by Section 14.2. Each Guarantor further agrees that, to the extent the waiver or agreement to withhold the exercise of its rights of subrogation, reimbursement, indemnification and contribution as set forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, any rights of subrogation, reimbursement or indemnification such Guarantor may have against any Borrower or against any collateral or security, and any rights of contribution such Guarantor may have against any such other guarantor, shall be junior and subordinate to any rights Agent or any Lender may have against any Borrower, to all right, title and interest Lender may have in any such collateral or security, and to any right Agent or any Lender may have against such other guarantor. If any amount shall be paid to any Guarantor on account of any such subrogation, reimbursement, indemnification or contribution rights at any time when all Guaranteed Obligations shall not have been finally and indefeasibly paid in full, such amount shall be held in trust for Agent and Lenders and shall forthwith be paid over to Agent to be credited and applied against the Guaranteed Obligations, whether matured or unmatured, in accordance with the terms hereof. 14.7. Subordination of Other Obligations. Any indebtedness of any Borrower or any Guarantor now or hereafter held by any Guarantor (the “Obligee Guarantor”) is hereby subordinated in right of payment to the Guaranteed Obligations, and any such indebtedness collected or received by the Obligee Guarantor after an Event of Default has occurred and is continuing shall be held in trust for Agent and Lenders and shall forthwith be paid over to Agent to be credited and applied against the Guaranteed Obligations but without affecting, impairing or limiting in any manner the liability of the Obligee Guarantor under any other provision hereof. 14.8. Continuing Guaranty. This Guaranty is a continuing guaranty and shall remain in effect until all of the Guaranteed Obligations shall have been indefeasibly paid in full and the Commitment shall have terminated and all Letters of Credit shall have expired or been cancelled. Each Guarantor hereby irrevocably waives any right to revoke this Guaranty as to future transactions giving rise to any Guaranteed Obligations. 14.9. Authority of Guarantors or Borrowers. It is not necessary for Agent or any Lender to inquire into the capacity or powers of any Guarantor or any Borrower or the officers, directors or any agents acting or purporting to act on behalf of any of them. 14.10. Financial Condition of Borrowers. Any Loan may be made to Borrowers or continued from time to time, without notice to or authorization from any Guarantor regardless of the financial or other condition of Borrowers at the time of any such grant or continuation. Neither Agent nor any Lender shall have any obligation to disclose or discuss with any Guarantor its assessment, or any Guarantor’s assessment, of the financial condition of any Borrower. Each Guarantor has adequate means to obtain information from each Borrower on a continuing basis concerning the financial condition of such Borrower and its ability to perform its obligations under the Loan Documents, and each Guarantor assumes the responsibility for

-106- being and keeping informed of the financial condition of Borrowers and of all circumstances bearing upon the risk of nonpayment of the Guaranteed Obligations. Each Guarantor hereby waives and relinquishes any duty on the part of Agent or any Lender to disclose any matter, fact or thing relating to the business, operations or conditions of any Borrower now known or hereafter known by Agent or any Lender. 14.11. Bankruptcy, etc. So long as any Guaranteed Obligations remain outstanding, no Guarantor shall, without the prior written consent of Agent, commence or join with any other Person in commencing any bankruptcy, reorganization or insolvency case or proceeding of or against any Borrower or any other Guarantor. 14.11.1. The obligations of Guarantors hereunder shall not be reduced, limited, impaired, discharged, deferred, suspended or terminated by any case or proceeding, voluntary or involuntary, involving the bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement of any Borrower or any other Guarantor or by any defense which any Borrower or any other Guarantor may have by reason of the order, decree or decision of any court or administrative body resulting from any such proceeding. 14.11.2. Each Guarantor acknowledges and agrees that any interest on any portion of the Guaranteed Obligations which accrues after the commencement of any case or proceeding referred to in Section 14.11.1 above (or, if interest on any portion of the Guaranteed Obligations ceases to accrue by operation of law by reason of the commencement of such case or proceeding, such interest as would have accrued on such portion of the Guaranteed Obligations if such case or proceeding had not been commenced) shall be included in the Guaranteed Obligations because it is the intention of Guarantors and Agent and Lenders that the Guaranteed Obligations which are guaranteed by Guarantors pursuant hereto should be determined without regard to any rule of law or order which may relieve any Borrower of any portion of such Guaranteed Obligations. Guarantors will permit any trustee in bankruptcy, receiver, debtor in possession, assignee for the benefit of creditors or similar person to pay Agent and Lenders, or allow the claim of Agent and Lenders in respect of, any such interest accruing after the date on which such case or proceeding is commenced. 14.11.3. In the event that all or any portion of the Guaranteed Obligations are paid by any Borrower, the obligations of Guarantors hereunder shall continue and remain in full force and effect or be reinstated, as the case may be, in the event that all or any part of such payment(s) are rescinded or recovered directly or indirectly from Agent or any Lender as a preference, fraudulent transfer or otherwise, and any such payments which are so rescinded or recovered shall constitute Guaranteed Obligations for all purposes hereunder. SECTION 15. MISCELLANEOUS 15.1. Consents, Amendments and Waivers. 15.1.1. Amendment. No modification of any Loan Document, including any extension or amendment of a Loan Document or any waiver of a Default or Event of Default, shall be effective without the prior written agreement of Agent (with the consent of Required Lenders) and each Obligor party to such Loan Document; provided, however, that

-107- (a) without the prior written consent of Agent, no modification shall be effective with respect to any provision in a Loan Document that relates to any rights, duties or discretion of Agent; (b) without the prior written consent of Issuing Bank, no modification shall be effective with respect to any LC Obligations or any other provision in a Loan Document that relates to any rights, duties or discretion of Issuing Bank; (c) without the prior written consent of each affected Lender, including a Defaulting Lender, no modification shall be effective that would (i) increase the Commitment of such Lender; (ii) reduce the amount of, or waive or delay payment of, any principal, interest or fees payable to such Lender (except as provided in Section 4.2); (iii) extend the Revolver Termination Date applicable to such Lender’s Obligations; or (iv) amend this clause (c); (d) without the prior written consent of all Lenders (except any Defaulting Lender), no modification shall be effective that would (i) alter Section 5.5.2, 7.1 (except to add Collateral) or 15.1.1; (ii) amend the definition of Borrowing Base (or any defined term used in such definition), Pro Rata or Required Lenders; (iii) increase any advance rate or decrease the Availability Reserve; (iv) release all or substantially all Collateral; or (v) except in connection with a merger, disposition or similar transaction expressly permitted hereby, release any Obligor from liability for any Obligations; and (e) without the prior written consent of a Secured Bank Product Provider, no modification shall be effective that affects its relative payment priority under Section 5.5.2. 15.1.2. Limitations. The agreement of Obligors shall not be necessary to the effectiveness of any modification of a Loan Document that deals solely with the rights and duties of Lenders, Agent and/or Issuing Bank as among themselves. Only the consent of the parties to any agreement relating to fees or a Bank Product shall be required for modification of such agreement, and no Bank Product provider (in such capacity) shall have any right to consent to modification of any Loan Document other than its Bank Product agreement. Any waiver or consent granted by Agent or Lenders hereunder shall be effective only if in writing and only for the matter specified. Notwithstanding Section 15.1.1, any amendments that Agent deems appropriate in connection with an increase in Revolver Commitments pursuant to Section 2.1.7 shall not require the consent of any Lender (other than Lenders that are increasing their Revolver Commitments at such time). 15.1.3. Payment for Consents. No Obligor will, directly or indirectly, pay any remuneration or other thing of value, whether by way of additional interest, fee or otherwise, to any Lender (in its capacity as a Lender hereunder) as consideration for agreement by such Lender with any modification of any Loan Documents, unless such remuneration or value is concurrently paid, on the same terms, on a Pro Rata basis to all Lenders providing their consent. 15.2. Indemnity. EACH OBLIGOR SHALL INDEMNIFY AND HOLD HARMLESS THE INDEMNITEES AGAINST ANY CLAIMS THAT MAY BE INCURRED BY OR ASSERTED AGAINST ANY INDEMNITEE, INCLUDING CLAIMS ASSERTED BY ANY OBLIGOR OR OTHER PERSON OR ARISING FROM THE

-108- NEGLIGENCE OF AN INDEMNITEE; PROVIDED THAT, IN NO EVENT SHALL ANY PARTY TO A LOAN DOCUMENT HAVE ANY OBLIGATION THEREUNDER TO INDEMNIFY OR HOLD HARMLESS AN INDEMNITEE WITH RESPECT TO A CLAIM THAT IS DETERMINED IN A NON-APPEALABLE JUDGMENT BY A COURT OF COMPETENT JURISDICTION TO RESULT FROM THE GROSS NEGLIGENCE OR WILLFUL MISCONDUCT OF SUCH INDEMNITEE. 15.3. Notices and Communications. 15.3.1. Notice Address. Subject to Section 4.1.4, all notices and other communications by or to a party hereto shall be in writing and shall be given to any Obligor, at Borrower Agent’s address shown on the signature pages hereof, and to any other Person at its address shown on the signature pages hereof (or, in the case of a Person who becomes a Lender after the Closing Date, at the address shown on its Assignment and Acceptance), or at such other address as a party may hereafter specify by notice in accordance with this Section 15.3. Each communication shall be effective only (a) if given by facsimile transmission, when transmitted to the applicable facsimile number, if confirmation of receipt is received; (b) if given by mail, three Business Days after deposit in the U.S. mail, with first-class postage pre-paid, addressed to the applicable address; or (c) if given by personal delivery, when duly delivered to the notice address with receipt acknowledged. Notwithstanding the foregoing, no notice to Agent pursuant to Section 2.1.4, 3.1.2, 4.1.1 or 4.3 shall be effective until actually received by the individual to whose attention at Agent such notice is required to be sent. Any written communication that is not sent in conformity with the foregoing provisions shall nevertheless be effective on the date actually received by the noticed party. Any notice received by Borrower Agent shall be deemed received by all Obligors. 15.3.2. Electronic Communications; Voice Mail. Electronic mail and internet websites may be used only for routine communications, such as delivery of Borrower Materials, administrative matters, distribution of Loan Documents, and matters permitted under Section 4.1.4. Agent and Lenders make no assurances as to the privacy and security of electronic communications. Electronic and voice mail may not be used as effective notice under the Loan Documents. 15.3.3. Platform. Borrower Materials shall be delivered pursuant to procedures approved by Agent, including electronic delivery (if possible) upon request by Agent to an electronic system maintained by Agent (“Platform”). Borrowers shall notify Agent of each posting of Borrower Materials on the Platform and the materials shall be deemed received by Agent only upon its receipt of such notice. Borrower Materials and other information relating to this credit facility may be made available to Lenders on the Platform. The Platform is provided “as is” and “as available.” Agent does not warrant the accuracy or completeness of any information on the Platform nor the adequacy or functioning of the Platform, and expressly disclaims liability for any errors or omissions in the Borrower Materials or any issues involving the Platform. NO WARRANTY OF ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD PARTY RIGHTS, OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY AGENT WITH RESPECT TO BORROWER MATERIALS OR THE PLATFORM. Lenders acknowledge that Borrower Materials may include material non-public information of Obligors and should not be made available to any personnel who do not wish to receive such information or who may be

-109- engaged in investment or other market-related activities with respect to any Obligor’s securities. No Agent Indemnitee shall have any liability to Obligors, Lenders or any other Person for losses, claims, damages, liabilities or expenses of any kind (whether in tort, contract or otherwise) relating to use by any Person of the Platform or delivery of Borrower Materials and other information through the Platform. 15.3.4. Non-Conforming Communications. Agent and Lenders may rely upon any communications purportedly given by or on behalf of any Obligor even if they were not made in a manner specified herein, were incomplete or were not confirmed, or if the terms thereof, as understood by the recipient, varied from a later confirmation. Each Obligor shall indemnify and hold harmless each Indemnitee from any liabilities, losses, costs and expenses arising from any electronic or telephonic communication purportedly given by or on behalf of a Obligor. 15.4. Performance of Obligors’ Obligations. Agent may, in its Permitted Discretion at any time and from time to time, at Borrowers’ expense, pay any amount or do any act required of an Obligor under any Loan Documents or otherwise lawfully requested by Agent to (a) enforce any Loan Documents or collect any Obligations; (b) protect, insure, maintain or realize upon any Collateral; or (c) defend or maintain the validity or priority of Agent’s Liens in any Collateral, including any payment of a judgment, insurance premium, warehouse charge, finishing or processing charge, or landlord claim, or any discharge of a Lien. All payments, costs and expenses (including Extraordinary Expenses) of Agent under this Section shall be reimbursed to Agent by Borrowers, within five days after demand, with interest from the date incurred until paid in full, at the Default Rate applicable to Base Rate Revolver Loans. Any payment made or action taken by Agent under this Section shall be without prejudice to any right to assert an Event of Default or to exercise any other rights or remedies under the Loan Documents. 15.5. Credit Inquiries. Agent and Lenders may (but shall have no obligation) to respond to usual and customary credit inquiries from third parties concerning any Obligor or Subsidiary. 15.6. Severability. Wherever possible, each provision of the Loan Documents shall be interpreted in such manner as to be valid under Applicable Law. If any provision is found to be invalid under Applicable Law, it shall be ineffective only to the extent of such invalidity and the remaining provisions of the Loan Documents shall remain in full force and effect. 15.7. Cumulative Effect; Conflict of Terms. The provisions of the Loan Documents are cumulative. The parties acknowledge that the Loan Documents may use several limitations or measurements to regulate similar matters, and they agree that these are cumulative and that each must be performed as provided. Except as otherwise provided in another Loan Document (by specific reference to the applicable provision of this Agreement), if any provision contained herein is in direct conflict with any provision in another Loan Document, the provision herein shall govern and control. 15.8. Counterparts. Any Loan Document may be executed in counterparts, each of which shall constitute an original, but all of which when taken together shall constitute a single contract. This Agreement shall become effective when Agent has received counterparts bearing the signatures of all parties hereto. Delivery of a signature page of any Loan Document by

-110- telecopy or other electronic means shall be effective as delivery of a manually executed counterpart of such agreement. 15.9. Entire Agreement. Time is of the essence with respect to all Loan Documents and Obligations. The Loan Documents constitute the entire agreement, and supersede all prior understandings and agreements, among the parties relating to the subject matter thereof. 15.10. Relationship with Lenders. The obligations of each Lender hereunder are several, and no Lender shall be responsible for the obligations or Commitments of any other Lender. Amounts payable hereunder to each Lender shall be a separate and independent debt.

To the fullest extent permitted by Applicable Law, each Obligor hereby waives and releases any claims that it may have against Agent, Lenders, their Affiliates and any arranger with respect to any breach of agency or fiduciary duty in connection with any transaction contemplated by a Loan Document. 15.12. Confidentiality. Each of Agent, Lenders and Issuing Bank shall maintain the confidentiality of all Information (as defined below), except that Information may be disclosed (a) to its Affiliates, and to its and their partners, directors, officers, employees, agents, advisors and representatives (provided such Persons are informed of the confidential nature of the Information and instructed to keep it confidential); (b) to the extent requested by any governmental, regulatory or self-regulatory authority purporting to have jurisdiction over it or its Affiliates; (c) to the extent required by Applicable Law or by any subpoena or other legal process; (d) to any other party hereto; (e) in connection with any action or proceeding relating to any Loan Documents or Obligations; (f) subject to an agreement containing provisions substantially the same as this Section, to any Transferee or any actual or prospective party (or its advisors) to any Bank Product; (g) with the consent of Borrower Agent; or (h) to the extent such Information (i) becomes publicly available other than as a result of a breach of this Section or (ii) is available to Agent, any Lender, Issuing Bank or any of their Affiliates on a nonconfidential basis from a source other than Obligors that has not obtained such information in breach of this

Each of Agent, Lenders and Issuing Bank acknowledges that (i) Information may include material non-public information; (ii) it has developed compliance procedures regarding the use of material non-public information; and (iii) it will handle such material non-public information in accordance with Applicable Law. 15.13. Certifications Regarding Senior Notes and Intercreditor Agreement.

-113- 15.21. Intercreditor Agreement. Notwithstanding anything to the contrary contained in this Agreement and each other Loan Document, the Liens, security interests and rights granted pursuant to this Agreement or any other Loan Document shall be subject to the terms, provisions and conditions of (and the exercise of any right or remedy by the Agent hereunder or thereunder shall be subject to the terms and conditions of), the Intercreditor Agreement. In the event of any conflict between this Agreement and any other Loan Document or the Intercreditor Agreement, as the case may be, the Intercreditor Agreement shall control, and no right, power, or remedy granted to the Agent hereunder or under any other Loan Document shall be exercised by the Agent, and no direction shall be given by the Agent, in contravention of the Intercreditor Agreement. With respect to any requirements herein or in any other Loan Document for any Obligor to deliver originals of certificated Equity Interests, Instruments, or similar documents constituting Collateral which is Senior Notes Priority Collateral, such requirements shall be deemed satisfied to the extent the requirements to deliver the same to the Senior Notes Agent in accordance with the Intercreditor Agreement and the Senior Notes Documents are in effect and are satisfied by such Obligor. To the extent that any covenants, representations or warranties set forth in this Agreement or any other Loan Document are untrue or incorrect solely as a result of the delivery to, or grant of possession or control to, the Senior Notes Agent in accordance with this Section 15.21, such representation or warranty shall not be deemed to be untrue or incorrect for purposes of this Agreement or such other Loan Document. 15.22. Senior Notes Priority Collateral.

Amendment and Restatement. This Agreement amends and restates in its entirety the Initial Loan Agreement. This Agreement and the other Loan Documents govern the present relationship between the Obligors, Agent and Lenders. This Agreement, however, is in no way intended, nor shall it be construed, to affect, replace, impair or extinguish the creation, attachment, perfection or priority of the security interests in, and other Liens on, the Collateral, which security interests and other Liens each of the Obligors, by this Agreement, acknowledges, reaffirms and confirms to Agent and Lenders. In addition, except as otherwise provided herein, all monetary obligations and liabilities and indebtedness created or existing under, pursuant to, or as a result of, the Initial Loan Agreement, other than Excluded Swap Obligations (the “Initial Loan Agreement Obligations”) shall continue in existence within the definition of “Obligations” under this Agreement, which obligations, liabilities and indebtedness the Obligors, by this Agreement, acknowledge, reaffirm and confirm. The Obligors agree that any outstanding commitment or other obligation to make advances or otherwise extend credit or credit support to any Obligor pursuant to the Initial Loan Agreement is superseded by, and renewed and consolidated under, this Agreement. The Obligors represent and warrant that none of them have assigned or otherwise transferred any rights arising under the Initial Loan Agreement. To the extent not amended and restated as of the Closing Date, the Loan Documents executed in connection with the Initial Loan Agreement and in effect prior to the Closing Date (the “Existing Loan Documents”) shall continue in full force and effect, are hereby ratified, reaffirmed and confirmed in all respects, and shall, for the avoidance of doubt, constitute “Loan

-114- Documents” under this Agreement. The terms of the Loan Documents that correspond to the Existing Loan Documents that have been amended and restated as of the Closing Date shall govern for any period occurring on or after the Closing Date, and the terms of such Existing Loan Documents prior to their amendment and restatement shall govern for any period beginning before the Closing Date and ending on the day immediately preceding the Closing Date. In furtherance of the foregoing, (i) each reference in any Loan Document to the “Loan Agreement”, any other Loan Document that is being amended and restated as of the Closing Date, “thereunder”, “thereof” or words of like import, is hereby amended, mutatis mutandis, as applicable in the context, to be a reference to, and shall thereafter mean, this Agreement or such other amended and restated Loan Document, as applicable in the context (as each may be amended, modified or supplemented and in effect from time to time) and (ii) the definition of any term defined in any Loan Document by reference to the terms defined in the “Loan Agreement” or any other Loan Document that is being amended and restated as of the Closing Date is hereby amended to be defined by reference to the defined term in this Agreement or such other amended and restated Loan Document, as applicable (as each may be amended, modified or supplemented and in effect from time to time). It is acknowledged and agreed that this Agreement is an “ABL Agreement” for all purposes under the Intercreditor Agreement, and, as of the date hereof, is the only “ABL Agreement” in existence for purposes of the Intercreditor Agreement, and the Agent is the “ABL Representative” for all purposes under the Intercreditor Agreement. In order to induce Lenders to enter into this Agreement on the Closing Date, each Obligor hereby represents, warrants and covenants to Lenders that it has determined that each Obligor will benefit specifically and materially from the amendment and restatement of the Initial Loan Agreement pursuant to this Agreement on the Closing Date and that each Obligor requested and bargained for the structure and terms of and security for the Loans contemplated by this Agreement on the Closing Date. 15.24. Release. EACH OBLIGOR HEREBY ACKNOWLEDGES THAT AS OF THE DATE HEREOF IT HAS NO DEFENSE, COUNTERCLAIM, OFFSET, CROSS COMPLAINT, CLAIM OR DEMAND OF ANY KIND OR NATURE WHATSOEVER THAT CAN BE ASSERTED TO REDUCE OR ELIMINATE ALL OR ANY PART OF ITS LIABILITY TO REPAY THE “OBLIGATIONS” OR TO SEEK AFFIRMATIVE RELIEF OR DAMAGES OF ANY KIND OR NATURE FROM ANY LENDER. EACH OBLIGOR HEREBY VOLUNTARILY AND KNOWINGLY RELEASES AND FOREVER DISCHARGES AGENT AND EACH LENDER AND THEIR RESPECTIVE PREDECESSORS, AGENTS, EMPLOYEES, SUCCESSORS AND ASSIGNS, FROM ALL POSSIBLE CLAIMS, DEMANDS, ACTIONS, CAUSES OF ACTION, DAMAGES, COSTS, EXPENSES, AND LIABILITIES (INCLUDING ALL STRICT LIABILITIES) WHATSOEVER, KNOWN OR UNKNOWN, ANTICIPATED OR UNANTICIPATED, SUSPECTED OR UNSUSPECTED, FIXED, CONTINGENT, OR CONDITIONAL, AT LAW OR IN EQUITY, ORIGINATING IN WHOLE OR IN PART ON OR BEFORE THE DATE OF THIS AGREEMENT, WHICH ANY OBLIGOR MAY NOW OR HEREAFTER HAVE AGAINST AGENT OR ANY LENDER OR ANY OF THEIR RESPECTIVE PREDECESSORS, AGENTS, EMPLOYEES, SUCCESSORS AND ASSIGNS, IF ANY, AND IRRESPECTIVE OF WHETHER ANY SUCH CLAIMS ARISE OUT OF CONTRACT, TORT, VIOLATION OF LAW OR REGULATIONS, OR OTHERWISE, TO THE EXTENT ARISING FROM ANY “LOANS,” INCLUDING, WITHOUT LIMITATION, ANY CONTRACTING FOR, CHARGING, TAKING,

-115- RESERVING, COLLECTING OR RECEIVING INTEREST IN EXCESS OF THE HIGHEST LAWFUL RATE APPLICABLE, THE EXERCISE OF ANY RIGHTS AND REMEDIES UNDER THE INITIAL LOAN AGREEMENT OR ANY OTHER LOAN DOCUMENT, AND NEGOTIATION FOR AND EXECUTION OF THIS AGREEMENT. EACH OBLIGOR WAIVES THE BENEFITS OF ANY LAW, WHICH MAY PROVIDE IN SUBSTANCE: “A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN ITS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY IT MUST HAVE MATERIALLY AFFECTED ITS SETTLEMENT WITH THE DEBTOR.” EACH OBLIGOR UNDERSTANDS THAT THE FACTS WHICH IT BELIEVES TO BE TRUE AT THE TIME OF MAKING THE RELEASE PROVIDED FOR HEREIN MAY LATER TURN OUT TO BE DIFFERENT THAN IT NOW BELIEVES, AND THAT INFORMATION WHICH IS NOT NOW KNOWN OR SUSPECTED MAY LATER BE DISCOVERED. EACH OBLIGOR ACCEPTS THIS POSSIBILITY, AND EACH OF THEM ASSUMES THE RISK OF THE FACTS TURNING OUT TO BE DIFFERENT AND NEW INFORMATION BEING DISCOVERED; AND EACH OF THEM FURTHER AGREES THAT THE RELEASE PROVIDED FOR HEREIN SHALL IN ALL RESPECTS CONTINUE TO BE EFFECTIVE AND NOT SUBJECT TO TERMINATION OR RESCISSION BECAUSE OF ANY DIFFERENCE IN SUCH FACTS OR ANY NEW INFORMATION.
