“(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

Underlying Issuer (including, as Issuing Lender’s agent) to Issue, a requested
Letter of Credit for the account of Parent or Borrowers, as applicable.

2

--------------------------------------------------------------------------------

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

3

--------------------------------------------------------------------------------

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;

4

--------------------------------------------------------------------------------

(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

5

--------------------------------------------------------------------------------

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

6

--------------------------------------------------------------------------------

“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.”

restating such Section in its entirety as follows:

Credit, this Agreement, or any term or provision therein or herein;
(ii)    payment against presentation of any draft, demand or claim for payment

or a transferee of such Person purporting to be a successor or transferee of the
beneficiary of such Letter of Credit;
(iii)    Issuing Lender, Underlying Issuer, or any of their respective branches
or Affiliates being the beneficiary of any Letter of Credit;

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),

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. The determination by Agent of any amount
due pursuant to this Section 3.01(m), as set forth in a certificate setting
forth the calculation thereof in reasonable detail, shall, in the absence of
manifest or demonstrable error, be final and conclusive and binding on all of
the parties hereto.”
(n)Section 3.01(n) of the Credit Agreement is hereby amended by amending and
restating such Section in its entirety as follows:
“(n)    Unless otherwise expressly agreed by Issuing Lender and Parent or
Borrowers, as applicable, when a Letter of Credit is Issued (including any such
agreement applicable to an Existing Letter of Credit), (i) the rules of the ISP
and the UCP shall apply to each standby Letter of Credit, and (ii) the rules of
the UCP shall apply to each commercial Letter of Credit.”
(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

10

--------------------------------------------------------------------------------

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. To induce the Lender Group to do so, and in consideration
thereof, each Borrower hereby jointly and severally agrees to indemnify each
member of the Lender Group and hold each member of the Lender Group harmless
against any and all liability, expense, loss or claim of damage or injury, made
against the Lender Group by any Borrower or by any third party whosoever,
arising from or incurred by reason of (i) the handling of the Loan Account and
Collateral of Borrowers as herein provided, or (ii) the Lender Group’s relying
on any instructions of Administrative Borrower, except that Borrowers will have
no liability to the relevant Agent Related Persons or Lender Related Persons
under this Section 11.23 with respect to any liability that has been finally
determined by a court of competent jurisdiction to have resulted solely from the
gross negligence or willful misconduct of such Agent Related Persons or Lender
Related Persons, as the case may be.”

Schedule in its entirety, and (ii) inserting the Schedule 11.02 attached hereto
in lieu thereof.

Exhibit in its entirety, and (ii) inserting the Exhibit A attached hereto in

or an Assistant Secretary (or other appropriate officer) of such New Borrower;
(c)    A certificate of the Secretary or Assistant Secretary (or other

in the Collateral of each New Borrower and in which the Agent requests that such
filing be made; and
(j)    An acknowledgment to the Intercreditor Agreement executed by each New
Borrower, in form and substance satisfactory to Agent.
The failure to comply with any of the covenants set forth in this Section 4

under the laws of the jurisdiction of its incorporation or formation, (ii) has
the power and authority and all governmental licenses, authorizations, consents
and approvals (A) to own its assets and carry on its business, and (B) to

in clauses (ii)(A), (iii) or (iv), to the extent that the failure to do so would
not reasonably be expected to have a Material Adverse Effect;

13

--------------------------------------------------------------------------------

(b)    The execution, delivery, and performance by it of this Amendment have
been duly authorized by all necessary corporate, limited liability company or
other applicable organizational action on the part of it, and do not and will
not (i) contravene the terms of any of its Organization Documents, (ii) conflict
with or result in any breach or contravention of, or the creation of any Lien

Obligation to which it is a party or any order, injunction, writ or decree of
any Governmental Authority to which it or its property is subject, or (iii)
violate any Requirement of Law.
(c)    This Amendment, when executed and delivered by it, constitutes the
legally valid and binding obligations of it, enforceable against it in
accordance with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, or similar laws affecting the enforcement of creditors’
rights generally or by equitable principles relating to enforceability.
(d)    The execution, delivery, and performance by it of this Amendment do not
and will not require any approval, consent, exemption, authorization, or other
action by, or notice to, or filing with, any Governmental Authority (except for
recordings or filings in connection with the Liens granted to the Agent under
the Collateral Documents and any filings that may be required under Securities
Laws in connection with the enforcement of such Liens).
(e)    No injunction, writ, temporary restraining order, or any order of any
nature purporting to enjoin or restrain the execution, delivery, and performance
of this Amendment has been issued and remains in force by any Governmental
Authority against any Borrower, any Guarantor, Agent, any other member of the
Lender Group, or any Bank Product Provider.
(f)    No Default or Event of Default has occurred and is continuing as of the
date of the effectiveness of this Amendment, and no condition exists which
constitutes a Default or an Event of Default.

qualified or modified by materiality in the text thereof) on and as of the date
hereof, as though made on and as of such date (except to the extent that such
representations and warranties relate solely to an earlier date, in which case
such representations and warranties shall continue to be true and correct in all
material respects (except that such materiality qualifier shall not be
applicable to any representations and warranties that already are qualified or
modified by materiality in the text thereof) as of such earlier date).
(h)    This Amendment has been entered into without force or duress, of the free
will of it, and its decision to enter into this Amendment is a fully informed
decision and it is aware of all legal and other ramifications of each such
decision.
(i)    It has read and understands this Amendment, has consulted with and been
represented by independent legal counsel of its own choosing in negotiations for
and the preparation of this Amendment, has read this Amendment in full and final
form, and has been advised by its counsel of its rights and obligations

expenses of any attorneys retained by Agent

14

--------------------------------------------------------------------------------

or any Lender) in connection with the preparation, negotiation, execution and
delivery of this Amendment and any documents and instruments relating hereto.
7.Release.
(a)    Effective on the date hereof, each Borrower and each Guarantor, for
itself and on behalf of its successors, assigns, and officers, directors,
employees, agents and attorneys, and any Person acting for or on behalf of, or
claiming through it, hereby waives, releases, remises and forever discharges
Agent and each Lender, each of their respective Affiliates, and each of their
respective successors in title, past, present and future officers, directors,
employees, limited partners, general partners, investors, attorneys, assigns,
subsidiaries, shareholders, trustees, agents and other professionals and all
other persons and entities to whom any member of the Lender Group would be
liable if such persons or entities were found to be liable to such Borrower or
such Guarantor (each a “Releasee” and collectively, the “Releasees”), from any
and all past, present and future claims, suits, liens, lawsuits, adverse
consequences, amounts paid in settlement, debts, deficiencies, diminution in
value, disbursements, demands, obligations, liabilities, causes of action,
damages, losses, costs and expenses of any kind or character, whether based in
equity, law, contract, tort, implied or express warranty, strict liability,
criminal or civil statute or common law (each a “Claim” and collectively, the
“Claims”), whether known or unknown, fixed or contingent, direct, indirect, or
derivative, asserted or unasserted, matured or unmatured, foreseen or
unforeseen, past or present, liquidated or unliquidated, suspected or
unsuspected, which such Borrower or such Guarantor ever had from the beginning
of the world to the date hereof and from the beginning of the world to the First
Amendment Effective Date, now has, or might hereafter have against any such
Releasee which relates, directly or indirectly to the Credit Agreement, any
other Loan Document, or to any acts or omissions of any such Releasee with
respect to the Credit Agreement or any other Loan Document, or to the
lender-borrower relationship evidenced by the Loan Documents, except for the
duties and obligations set forth in this Amendment. 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.

15

--------------------------------------------------------------------------------

(b)    Each Borrower and each Guarantor, for itself and on behalf of its
successors, assigns, and officers, directors, employees, agents and attorneys,
and any Person acting for or on behalf of, or claiming through it, hereby
absolutely, unconditionally and irrevocably, covenants and agrees with and in
favor of each Releasee above that it will not sue (at law, in equity, in any
regulatory proceeding or otherwise) any Releasee on the basis of any Claim
released, remised and discharged by such Person pursuant to the above 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.
8.CHOICE OF LAW AND VENUE; JURY TRIAL WAIVER; JUDICIAL REFERENCE PROVISION. THIS
AMENDMENT SHALL BE SUBJECT TO THE PROVISIONS REGARDING CHOICE OF LAW AND VENUE,
JURY TRIAL WAIVER AND JUDICIAL REFERENCE PROVISION SET FORTH IN SECTION 11.16 OF
THE CREDIT AGREEMENT, AND SUCH PROVISIONS ARE INCORPORATED HEREIN BY THIS
REFERENCE, MUTATIS MUTANDIS.
9.Amendments. This Amendment cannot be altered, amended, changed or modified in
any respect except in accordance with Section 11.01 of the Credit Agreement.
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.
(a)    The Credit Agreement, as amended hereby, and each of the other Loan
Documents shall be and remain in full force and effect in accordance with their
respective terms and hereby are ratified and confirmed in all respects. The
execution, delivery, and performance of this Amendment shall not operate, except
as expressly set forth herein, as a modification or waiver of any right, power,
or remedy of Agent or any Lender under the Credit Agreement or any other Loan
Document. 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

16

--------------------------------------------------------------------------------

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. This Amendment, and the terms and provisions hereof, the
Credit Agreement and the other Loan Documents constitute the entire
understanding and agreement between the parties hereto with respect to the
subject matter hereof and supersede any and all prior or contemporaneous
amendments or understandings with respect to the subject matter hereof, whether
express or implied, oral or written.
13.Integration. This Amendment, together with the other Loan Documents,
incorporates all negotiations of the parties hereto with respect to the subject
matter hereof and is the final expression and agreement of the parties hereto
with respect to the subject matter hereof.
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.

17

--------------------------------------------------------------------------------

16.Severability. In case any provision in this Amendment shall be invalid,
illegal or unenforceable, such provision shall be severable from the remainder
of this Amendment and the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby.

the relationship between the Agent, on the one hand, and the Specified Bank

obligations and liabilities of Parent, Borrowers, and the other Loan Parties to
