(d)Section 3.01(a) of the Credit Agreement is hereby amended by amending and restating such Section in its entirety as follows:

“(a)    Subject to the terms and conditions of this Agreement, upon the request of Parent or any Borrower made in accordance herewith, and prior to the Revolving Loan Maturity Date, Issuing Lender agrees to Issue, or to cause an Underlying Issuer (including, as Issuing Lender’s agent) to Issue, a requested Letter of Credit for the account of Parent or Borrowers, as applicable.

If Issuing Lender, at its option, elects to cause an Underlying Issuer to Issue a requested Letter of Credit, then Issuing Lender agrees that it will enter into arrangements relative to the reimbursement of such Underlying Issuer (which may include, among other means, by becoming an applicant with respect to such Letter of Credit or entering into undertakings or other arrangements that provide for reimbursement of such Underlying Issuer with respect to such drawings under Letter of Credit; each such obligation or undertaking, irrespective of whether in writing, a “Reimbursement Undertaking”) with respect to Letters of Credit Issued by such Underlying Issuer for the account of Parent or Borrowers, as applicable. By submitting a request to Issuing Lender for the Issuance of a Letter of Credit, Parent or Borrowers, as applicable, shall be deemed to have requested that (i) Issuing Lender Issue, or (ii) an Underlying Issuer Issue the requested Letter of Credit (and, in such case, to have requested Issuing Lender to Issue a Reimbursement Undertaking with respect to such requested Letter of Credit). Parent acknowledges and agrees that Parent is and shall be deemed to be an applicant (within the meaning of Section 5102(a)(2) of the UCC) with respect to each Underlying Letter of Credit which it requests. Borrowers acknowledge and agree that Borrowers are and shall be deemed to be applicants (within the meaning of Section 5102(a)(2) of the UCC) with respect to each Underlying Letter of Credit which they request. Each request for the Issuance of a Letter of Credit, or the amendment, renewal, or extension of any outstanding Letter of Credit, shall be irrevocable and shall be made in writing by a Responsible Officer of Administrative Borrower and delivered to Issuing Lender via telefacsimile or other electronic method of transmission reasonably acceptable to Issuing Lender and reasonably in advance of the requested date of Issuance, amendment, renewal, or extension. Each such request shall be in form and substance reasonably satisfactory to Issuing Lender and (i) shall specify (A) the amount of such Letter of Credit, (B) the date of Issuance, amendment, renewal, or extension of such Letter of Credit, (C) the proposed expiration date of such Letter of Credit, (D) the name and address of the beneficiary of the Letter of Credit, and (E) such other information (including, the conditions to drawing, and, in the case of an amendment, renewal, or extension, identification of the Letter of Credit to be so amended, renewed, or extended) as shall be necessary to prepare, amend, renew, or extend such Letter of Credit, and (ii) shall be accompanied by such Issuer Documents as Agent, Issuing Lender or Underlying Issuer may request or require, to the extent that such requests or requirements are consistent with the Issuer Documents that Issuing Lender or Underlying Issuer generally requests for Letters of Credit in similar circumstances. Issuing Lender’s or Underlying Issuer’s records of the content of any such request will be conclusive. Anything contained herein to the contrary notwithstanding, Issuing Lender may, but shall not be obligated to, Issue or cause the Issuance of a Letter of Credit or to Issue a Reimbursement Undertaking in respect of an Underlying Letter of Credit, in either case, that supports the obligations of Parent or its Subsidiaries (1) in respect of (A) a lease of real property, or (B) an employment contract, or (2) at any time that one or more of the Lenders is a Defaulting Lender.”

(e)Section 3.01(d) of the Credit Agreement is hereby amended by amending and restating such Section in its entirety as follows:

“(d)    Any Issuing Lender (other than WFCF or any of its Affiliates) shall notify Agent in writing no later than the Business Day immediately following the Business Day on which such Issuing Lender issued any Letter of Credit; provided, that (y) until Agent advises any such Issuing Lender that the provisions of Section 5.02 are not satisfied, or (z) unless the aggregate amount of the Letters of Credit issued in any such week exceeds such amount as shall be agreed by Agent and such Issuing Lender, such Issuing Lender shall be required to so notify Agent in writing only once each week of the Letters of Credit issued by such Issuing Lender during the immediately preceding week as well as the daily amounts outstanding for the prior week, such notice to be furnished on

such day of the week as Agent and such Issuing Lender may agree. Each Loan Party and the Lender Group hereby acknowledge and agree that all Existing Letters of Credit shall constitute Letters of Credit under this Agreement on and after the date of this Agreement with the same effect as if such Existing Letters of Credit were Issued by Issuing Lender or an Underlying Issuer at the request of Parent or Borrowers on the date of this Agreement. Each Letter of Credit shall be in form and substance reasonably acceptable to Issuing Lender, including the requirement that the amounts payable thereunder must be payable in Dollars. If Issuing Lender makes a payment under a Letter of Credit or an Underlying Issuer makes a payment under an Underlying Letter of Credit, Borrowers shall pay to Agent an amount equal to the applicable Letter of Credit Disbursement on the date such Letter of Credit Disbursement is made and, in the absence of such payment, the amount of the Letter of Credit Disbursement immediately and automatically shall be deemed to be a Revolving Loan hereunder (notwithstanding any failure to satisfy any condition precedent set forth in Section 5) and, initially, shall bear interest at the rate then applicable to Revolving Loans that are Base Rate Loans. Without duplication of the immediately preceding sentence, if Issuing Lender or an Underlying Issuer makes a payment under a Guarantor L/C, Borrowers shall pay to Agent an amount equal to the applicable Letter of Credit Disbursement on the date such Letter of Credit Disbursement is made and, in the absence of such payment, the amount of the Letter of Credit Disbursement immediately and automatically shall be deemed to be a Revolving Loan hereunder and, initially, shall bear interest at the rate then applicable to Revolving Loans that are Base Rate Loans (the obligations of Borrowers pursuant to this sentence are referred to herein as “Borrowers’ Guarantor L/C Obligations”). If a Letter of Credit Disbursement is deemed to be a Revolving Loan hereunder, Borrowers’ obligation to pay the amount of such Letter of Credit Disbursement to Issuing Lender shall be automatically converted into an obligation to pay the resulting Revolving Loan. Promptly following receipt by Agent of any payment from Borrowers pursuant to this paragraph, Agent shall distribute such payment to Issuing Lender or, to the extent that Revolving Lenders have made payments pursuant to Section 3.01(e) to reimburse Issuing Lender, then to such Revolving Lenders and Issuing Lender as their interests may appear.”

(f)Section 3.01(f) of the Credit Agreement is hereby amended by amending and restating such Section in its entirety as follows:

“(f)    Parent and each Borrower hereby agrees to indemnify, defend, and hold harmless each member of the Lender Group (including Issuing Lender and its branches, Affiliates, and correspondents), each Underlying Issuer (including its branches, Affiliates, and correspondents), and each such Person’s respective directors, officers, employees, attorneys and agents (each, including Issuing Lender and Underlying Issuer, a “Letter of Credit Related Person”) (to the fullest extent permitted by law) from and against any and all claims, demands, suits, actions, investigations, proceedings, liabilities, fines, costs, penalties, and damages, and all reasonable fees and disbursements of attorneys, experts, or consultants and all other costs and expenses actually incurred in connection therewith or in connection with the enforcement of this indemnification (as and when they are incurred and irrespective of whether suit is brought), which may be incurred by or awarded against any such Letter of Credit Related Person (other than Taxes, which shall be governed by Section 4.01) (the “Letter of Credit Indemnified Costs”), and which arise out of or in connection with, or as a result of:

(i)    any Letter of Credit or Reimbursement Undertaking or any pre-advice of its Issuance;

(ii)    any transfer, sale, delivery, surrender or endorsement of any Drawing Document at any time(s) held by any such Letter of Credit Related Person in connection with any Letter of Credit or Reimbursement Undertaking;

(iii)    any action or proceeding arising out of, or in connection with, any Letter of Credit or Reimbursement Undertaking (whether administrative, judicial or in connection with arbitration), including any action or proceeding to compel or restrain any presentation or payment under any Letter of Credit or Reimbursement Undertaking, or for the wrongful dishonor of, or honoring a presentation under, any Letter of Credit or Reimbursement Undertaking;

(iv)    any independent undertakings issued by the beneficiary of any Letter of Credit or Reimbursement Undertaking;

(v)    any unauthorized instruction or request made to Issuing Lender or Underlying Issuer in connection with any Letter of Credit or requested Letter of Credit, Reimbursement Undertaking or requested Reimbursement Undertaking, or error in computer or electronic transmission;

(vi)    an adviser, confirmer or other nominated person seeking to be reimbursed, indemnified or compensated;

(vii)    any third party seeking to enforce the rights of an applicant, beneficiary, nominated person, transferee, assignee of Letter of Credit or Reimbursement Undertaking proceeds or holder of an instrument or document;

(viii)    the fraud, forgery or illegal action of parties other than the Letter of Credit Related Person;

(ix)    Issuing Lender’s or Underlying Issuer’s performance of the obligations of a confirming institution or entity that wrongfully dishonors a confirmation; or

(x)    the acts or omissions, whether rightful or wrongful, of any present or future de jure or de facto governmental or regulatory authority or cause or event beyond the control of the Letter of Credit Related Person;

in each case, including that resulting from the Letter of Credit Related Person’s own negligence; provided, that such indemnity shall not be available to any Letter of Credit Related Person claiming indemnification under clauses (i) through (x) above to the extent that such Letter of Credit Indemnified Costs may be finally determined in a final, non-appealable judgment of a court of competent jurisdiction to have resulted directly from the gross negligence or willful misconduct of the Letter of Credit Related Person claiming indemnity. Parent and each Borrower agrees to be bound by the Underlying Issuer’s regulations and interpretations of any Letter of Credit or by Issuing Lender’s interpretations of any Reimbursement Undertaking even though this interpretation may be different from Parent’s or such Borrower’s own. Parent and Borrowers understand that the Reimbursement Undertakings may require Issuing Lender to indemnify the Underlying Issuer for certain costs or liabilities arising out of claims by Parent or Borrowers against such Underlying Issuer. Parent and each Borrower hereby agrees to indemnify, defend, and hold harmless Issuing Lender and each other Letter of Credit Related Person from and against any and all Letter of Credit Indemnified Costs as a result of Issuing Lender’s indemnification of an Underlying Issuer; provided, that such indemnity shall not be available to any Letter of Credit Related Person claiming

indemnification to the extent that such Letter of Credit Indemnified Costs may be finally determined in a final, non-appealable judgment of a court of competent jurisdiction to have resulted directly from the gross negligence or willful misconduct of the Letter of Credit Related Person claiming indemnity. Borrowers hereby agree to pay the Letter of Credit Related Person claiming indemnity on demand from time to time all amounts owing under this Section 3.01(f). If and to the extent that the obligations of Borrowers under this Section 3.01(f) are unenforceable for any reason, Borrowers agree to make the maximum contribution to the Letter of Credit Indemnified Costs permissible under applicable law. This indemnification provision shall survive termination of this Agreement, all Letters of Credit, and all Reimbursement Undertakings.”

(g)Section 3.01(g) of the Credit Agreement is hereby amended by amending and restating such Section in its entirety as follows:

“(g)    The liability of Issuing Lender, Underlying Issuer, or any other Letter of Credit Related Person under, in connection with or arising out of any Letter of Credit (or pre-advice), regardless of the form or legal grounds of the action or proceeding, shall be limited to direct damages suffered by Parent or Borrowers that are caused directly by Issuing Lender’s or Underlying Issuer’s gross negligence or willful misconduct in (i) honoring a presentation under a Letter of Credit that on its face does not at least substantially comply with the terms and conditions of such Letter of Credit, (ii) failing to honor a presentation under a Letter of Credit that strictly complies with the terms and conditions of such Letter of Credit, or (iii) retaining Drawing Documents presented under a Letter of Credit. Issuing Lender and Underlying Issuer shall be deemed to have acted with due diligence and reasonable care if Issuing Lender’s or Underlying Issuer’s conduct is in accordance with Standard Letter of Credit Practice or in accordance with this Agreement. Parent and Borrowers’ aggregate remedies against Issuing Lender, Underlying Issuer, and any Letter of Credit Related Person for wrongfully honoring a presentation under any Letter of Credit or wrongfully retaining honored Drawing Documents shall in no event exceed the aggregate amount paid by Borrowers to Issuing Lender in respect of the honored presentation in connection with such Letter of Credit under Section 3.01(d), plus interest at the rate then applicable to Base Rate Loans hereunder. Parent and Borrowers shall take commercially reasonable action to avoid and mitigate the amount of any damages claimed against Issuing Lender, Underlying Issuer, or any other Letter of Credit Related Person, including by enforcing its rights against the beneficiaries of the Letters of Credit. Any claim by Parent or Borrowers under or in connection with any Letter of Credit shall be reduced by an amount equal to the sum of (x) the amount (if any) saved by Borrowers as a result of the breach or alleged wrongful conduct complained of; and (y) the amount (if any) of the loss that would have been avoided had Parent or Borrowers, as applicable, taken all reasonable steps to mitigate any loss, and in case of a claim of wrongful dishonor, by specifically and timely authorizing Issuing Lender to effect a cure.”

(h)Section 3.01(h) of the Credit Agreement is hereby amended by amending and restating such Section in its entirety as follows:

“(h)    Parent and Borrowers, as applicable, are responsible for preparing or approving the final text of the Letter of Credit as issued by Issuing Lender or Underlying Issuer, irrespective of any assistance Issuing Lender or Underlying Issuer may provide such as drafting or recommending text or by Issuing Lender’s or Underlying Issuer’s use or refusal to use text submitted by Parent or Borrowers, as applicable. Parent is solely responsible for the suitability of the Letter of Credit for Parent’s purposes. Parent and Borrowers are solely responsible for the suitability of the Letter of Credit for Parent’s and Borrowers’ purposes. With respect to any Letter of Credit containing an

“automatic amendment” to extend the expiration date of such Letter of Credit, Issuing Lender or Underlying Issuer, as applicable, in its sole and absolute discretion, may give notice of nonrenewal of such Letter of Credit and, if Parent or Borrowers, as applicable, do not at any time want such Letter of Credit to be renewed, Administrative Borrower will so notify Agent and Issuing Lender at least 15 calendar days before Issuing Lender or Underlying Issuer, as applicable, is required to notify the beneficiary of such Letter of Credit or any advising bank of such nonrenewal pursuant to the terms of such Letter of Credit.”

(i)Section 3.01(i) of the Credit Agreement is hereby amended by amending and restating such Section in its entirety as follows:

(iii)    Issuing Lender, Underlying Issuer, or any of their respective branches or Affiliates being the beneficiary of any Letter of Credit;

(iv)    Issuing Lender, Underlying Issuer, or any correspondent honoring a drawing against a Drawing Document up to the amount available under any Letter of Credit even if such Drawing Document claims an amount in excess of the amount available under the Letter of Credit;

(v)    the existence of any claim, set-off, defense or other right that Parent, any of its Subsidiaries, or any other Person may have at any time against any beneficiary, any assignee of proceeds, Issuing Lender, Underlying Issuer, or any other Person;

(vi)    any other event, circumstance or conduct whatsoever, whether or not similar to any of the foregoing that might, but for this Section 3.01(i), constitute a legal or equitable defense to or discharge of, or provide a right of set-off against, any Parent’s, any Borrower’s or any of their respective Subsidiaries’ reimbursement and other payment obligations and liabilities, arising under, or in connection with, any Letter of Credit, whether against Issuing Lender, Underlying Issuer, the beneficiary or any other Person; or

(vii)    the fact that any Default or Event of Default shall have occurred and be continuing;

Issuer following reimbursement or payment of the obligations and liabilities, including reimbursement and other payment obligations, of Borrowers to Issuing Lender or Underlying Issuer arising under, or in connection with, this Section 3.01 or any Letter of Credit.”

(i)    honor of a presentation under any Letter of Credit that on its face substantially complies with the terms and conditions of such Letter of Credit, even if the Letter of Credit requires strict compliance by the beneficiary;

(ii)    honor of a presentation of any Drawing Document that appears on its face to have been signed, presented or issued (A) by any purported successor or transferee of any beneficiary or other Person required to sign, present or issue such Drawing Document, or (B) under a new name of the beneficiary;

(m)Section 3.01(m) of the Credit Agreement is hereby amended by amending and restating such Section in its entirety as follows:

“(m)    If by reason of (i) any Change in Law, or (ii) compliance by Issuing Lender, any other member of the Lender Group, or Underlying Issuer with any direction, request, or requirement (irrespective of whether having the force of law) of any Governmental Authority or monetary

(i)    any reserve, deposit, or similar requirement is or shall be imposed or modified in respect of any Letter of Credit or Reimbursement Undertaking Issued or caused to be Issued hereunder or hereby, or

(ii)    there shall be imposed on Issuing Lender, any other member of the Lender Group, or Underlying Issuer any other condition regarding any Letter of Credit or Reimbursement Undertaking,

and the result of the foregoing is to increase, directly or indirectly, the cost to Issuing Lender, any other member of the Lender Group, or an Underlying Issuer of Issuing, making, participating in, or maintaining any Reimbursement Undertaking or Letter of Credit or to reduce the amount receivable in respect thereof, then, and in any such case, Agent may, at any time within a reasonable period after the additional cost is incurred or the amount received is reduced, notify the Administrative Borrower, and Borrowers shall pay within 30 days after demand therefor, such amounts as Agent may specify to be necessary to compensate Issuing Lender, any other member of the Lender Group, or an Underlying Issuer for such additional cost or reduced receipt, together with interest on such amount from the date of such demand until payment in full thereof at the rate then applicable to Base Rate Loans hereunder; provided, that (A) Borrowers shall not be required to provide any compensation pursuant to this Section 3.01(m) for any such amounts incurred more than 180 days prior to the date on which the demand for payment of such amounts is first made to the Administrative Borrower, and (B) if an event or circumstance giving rise to such amounts is retroactive, then the 180-day period referred to above shall be extended to include the period of retroactive effect thereof.

(o)Section 11.23 of the Credit Agreement is hereby amended by amending and restating such Section in its entirety as follows:

“Section 11.23        Stock Building Supply, LLC as Agent for Borrowers. Each Borrower hereby irrevocably appoints Stock Building Supply, LLC as the borrowing agent and attorney-in-fact for all Borrowers (“Administrative Borrower”) which appointment shall remain in full force and effect unless and until the Agent shall have received prior written notice signed by each Borrower that such appointment has been revoked and that another Borrower has been appointed Administrative Borrower. Each Borrower hereby irrevocably appoints and authorizes Administrative Borrower (a) to provide the Agent with all notices with respect to Revolving Loans and Letters of Credit obtained for the benefit of any Borrower and all other notices and instructions under this Agreement and the other Loan Documents (and any notice or instruction provided by Administrative Borrower shall be deemed to be given by Borrowers hereunder and shall bind each

Borrower), (b) to receive notices and instructions from members of the Lender Group (and any notice or instruction provided by any member of the Lender Group to Administrative Borrower in accordance with the terms hereof shall be deemed to have been given to each Borrower), and (c) to take such action as Administrative Borrower deems appropriate on its behalf to obtain Revolving Loans and Letters of Credit and to exercise such other powers as are reasonably incidental thereto to carry out the purposes of this Agreement. It is understood that the handling of the Loan Account and Collateral in a combined fashion, as more fully set forth herein, is done solely as an accommodation to Borrowers in order to utilize the collective borrowing powers of Borrowers in the most efficient and economical manner and at their request, and that Lender Group shall not incur liability to any Borrower as a result hereof. Each Borrower expects to derive benefit, directly or indirectly, from the handling of the Loan Account and the Collateral in a combined fashion since the successful operation of each Borrower is dependent on the continued successful performance of the integrated group.

As to each and every Claim released hereunder, each Borrower and each Guarantor hereby represents that it has received the advice of legal counsel with regard to the releases contained herein, and having been so advised, specifically waives the benefit of the provisions of Section 1542 of the Civil Code of California which provides as follows:

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH THE CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS OR HER FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM OR HER MUST HAVE MATERIALLY AFFECTED HIS OR HER SETTLEMENT WITH THE DEBTOR.”

As to each and every Claim released hereunder, each Borrower and each Guarantor also waives the benefit of each other similar provision of applicable federal or state law (including without limitation the laws of the state of California), if any, pertaining to general releases after having been advised by its legal counsel with respect thereto.

Each Borrower and each Guarantor acknowledges that it may hereafter discover facts different from or in addition to those now known or believed to be true with respect to such Claims and agrees that this instrument shall be and remain effective in all respects notwithstanding any such differences or additional facts. Each Borrower and each Guarantor understands, acknowledges and agrees that the release set forth above may be pleaded as a full and complete defense and may be used as a basis for an injunction against any action, suit or other proceeding which may be instituted, prosecuted or attempted in breach of the provisions of such release.

Each Borrower and each Guarantor further agrees that it shall not dispute the validity or enforceability of the Credit Agreement or any of the other Loan Documents or any of its obligations thereunder, or the validity, priority, enforceability or the extent of Agent’s Lien on any item of Collateral under the Credit Agreement or the other Loan Documents. If any Borrower, any Guarantor, or any of their respective successors, assigns, or officers, directors, employees, agents or attorneys, or any Person acting for or on behalf of, or claiming through it violate the foregoing covenant, such Person, for itself and its successors, assigns and legal representatives, agrees to pay, in addition to such other damages as any Releasee may sustain as a result of such violation, all attorneys’ fees and costs incurred by such Releasee as a result of such violation.

10.Counterpart Execution. This Amendment may be executed in any number of counterparts and by different parties on separate counterparts, each of which, when executed and delivered, shall be deemed to be an original, and all of which, when taken together, shall constitute but one and the same Amendment. Delivery of an executed counterpart of this Amendment by telefacsimile or other electronic method of transmission shall be equally as effective as delivery of an original executed counterpart of this Amendment. Any party delivering an executed counterpart of this Amendment by telefacsimile or other electronic method of transmission also shall deliver an original executed counterpart of this Amendment, but the failure to deliver an original executed counterpart shall not affect the validity, enforceability, and binding effect of this Amendment.

11.Effect on Loan Documents.

Except for the amendments to the Credit Agreement expressly set forth herein, the Credit Agreement and the other Loan Documents shall remain unchanged and in full force and effect. The modifications set forth herein are limited to the specifics hereof (including facts or occurrences on which the same are based), shall not apply with respect to any facts or occurrences other than those on which the same are based, shall neither excuse any future non-compliance with the Loan Documents nor operate as a waiver of any Default or Event of Default, shall not operate as a consent to any waiver, consent or further amendment or other matter under the Loan Documents, and shall not be construed as an indication that any future waiver or amendment of covenants or any other provision of the Credit Agreement or any other Loan Document will be agreed to, it being understood that the granting

or denying of any waiver or amendment which may hereafter be requested by Borrowers remains in the sole and absolute discretion of Agent and Lenders. To the extent that any terms or provisions of this Amendment conflict with those of the Credit Agreement or the other Loan Documents, the terms and provisions of this Amendment shall control.

(b)    Upon and after the effectiveness of this Amendment, each reference in the Credit Agreement to “this Agreement”, “hereunder”, “herein”, “hereof” or words of like import referring to the Credit Agreement, and each reference in the other Loan Documents to “the Credit Agreement”, “thereunder”, “therein”, “thereof” or words of like import referring to the Credit Agreement, shall mean and be a reference to the Credit Agreement as modified and amended hereby.

(c)    To the extent that any of the terms and conditions in any of the Loan Documents shall contradict or be in conflict with any of the terms or conditions of the Credit Agreement, after giving effect to this Amendment, such terms and conditions are hereby deemed modified or amended accordingly to reflect the terms and conditions of the Credit Agreement as modified or amended hereby.

(d)    This Amendment is a Loan Document.

(e)    This Amendment shall be subject to the interpretive provisions of Section 1.02 of the Credit Agreement.

12.Entire Agreement.

14.Reaffirmation of Obligations. Each of Parent and each Borrower hereby (a) acknowledges and reaffirms its obligations owing to Agent, each other member of the Lender Group, and the Bank Product Providers under each Loan Document to which it is a party, and (b) agrees that each of the Loan Documents to which it is a party is and shall remain in full force and effect. Each of Parent and each Borrower hereby (i) further ratifies and reaffirms the validity and enforceability of all of the Liens and security interests heretofore granted, pursuant to and in connection with the Security Agreement or any other Loan Document to Agent, on behalf and for the benefit of each member of the Lender Group and each Bank Product Provider, as collateral security for the obligations under the Loan Documents in accordance with their respective terms, and (ii) acknowledges that all of such Liens and security interests, and all Collateral heretofore pledged as security for such obligations, continue to be and remain collateral for such obligations from and after the date hereof (including, without limitation, from after giving effect to this Amendment).

15.Ratification. Each of Parent and each Borrower hereby restates, ratifies and reaffirms each and every term and condition set forth in the Credit Agreement and the Loan Documents effective as of the date hereof and as modified hereby.

Specified Bank Products Provider and Agent each agree that the Agency Provisions which govern the relationship, and certain representations, acknowledgements, appointments, rights, restrictions, and agreements, between the Agent, on the one hand, and the Lenders or the Lender Group, on the other hand, shall, from and after the date of this agreement also apply to and govern, mutatis mutandis, the relationship between the Agent, on the one hand, and the Specified Bank Product Provider with respect to the Bank Products provided pursuant to the Specified Bank Product Agreement[s], on the other hand.

2.    Acknowledgement of Certain Provisions of Credit Agreement. The Specified Bank Products Provider hereby acknowledges that it has reviewed the provisions of Section 9.03, Article 10, Section 11.01, and Section 11.18 of the Credit Agreement, including, as applicable, the defined terms used therein, and agrees to be bound by the provisions thereof. Without limiting the generality of any of the foregoing referenced provisions, Specified Bank Product Provider understands and agrees that its rights and benefits under the Loan Documents consist solely of it being a beneficiary of the Liens and security interests granted to Agent and the right to share in proceeds of the Collateral to the extent set forth in the Credit Agreement.

3.    Reporting Requirements. Agent shall have no obligation to calculate the amount due and payable with respect to any Bank Products. On a monthly basis (not later than the 10th Business Day of each calendar month) or as more frequently as Agent shall request, the Specified Bank Products Provider agrees to provide Agent with a written report, in form and substance satisfactory to Agent, detailing Specified Bank Products Provider’s reasonable determination of the liabilities and obligations (and mark- to-market exposure (if any)) of Parent, Borrowers, and the other Loan Parties in respect of the Bank Products provided by Specified Bank Products Provider pursuant to the Specified Bank Products Agreement[s].

If Agent chooses to implement a reserve, Specified Bank Products Provider acknowledges and agrees that Agent shall be entitled to rely on the information in the reports described above to establish the Bank Product Reserve Amount.

5.    Bank Product Obligations. From and after the delivery to Agent of this agreement duly executed by Specified Bank Product Provider and the acknowledgement of this agreement by Agent and Stock Building Supply, LLC, a North Carolina limited liability company (“Administrative Borrower”), the obligations and liabilities of Parent, Borrowers, and the other Loan Parties to Specified Bank Product Provider in respect of Bank Products evidenced by the Specified Bank Product Agreement[s] shall constitute Bank Product Obligations (and which, in turn, shall constitute Obligations), and Specified Bank Product Provider shall constitute a Bank Product Provider until such time as Specified Bank Products Provider or its Affiliate is no longer a Lender. Specified Bank Products Provider acknowledges that other Bank Products (which may or may not be Specified Bank Products) may exist at any time.

6.    Notices. All notices and other communications provided for hereunder shall be given in the form and manner provided in Section 11.02 of the Credit Agreement, and, if to Agent, shall be mailed, sent, or delivered to Agent in accordance with Section 11.02 in the Credit Agreement, if to Borrowers, shall be mailed, sent, or delivered to Administrative Borrower in accordance with Section 11.02 in the Credit Agreement, and, if to Specified Bank Products Provider, shall be mailed, sent, or delivered to the address set forth below, or, in each case as to any party, at such other address as shall be designated by such party in a written notice to the other party.

Each of such counterparts shall be deemed to be an original, and all of such counterparts, taken together, shall constitute but one and the same agreement. Delivery of an executed counterpart of this agreement by telefacsimile or other means of electronic transmission shall be equally effective as delivery of a manually executed counterpart.

8.    Governing Law, Etc. THIS AGREEMENT SHALL BE SUBJECT TO THE PROVISIONS REGARDING CHOICE OF LAW AND VENUE, JURY TRIAL WAIVER, AND JUDICIAL REFERENCE SET FORTH IN SECTION 11.16 OF THE CREDIT AGREEMENT, AND SUCH PROVISIONS ARE INCORPORATED HEREIN BY THIS REFERENCE, MUTATIS MUTANDIS.
