          WHEREAS, each Guarantor is a direct or indirect Subsidiary of the Borrower;

          WHEREAS, it is a condition precedent to the making of Loans to the Borrower and the issuance of, and participation in, Letters of Credit for the account of the Borrower under the Credit Agreement, that each Guarantor shall have executed and delivered to the Administrative Agent this Guaranty; and

          WHEREAS, each Guarantor will obtain benefits from the incurrence of Loans by the Borrower and the issuance of, and participation in, Letters of Credit for the account of the Borrower under the Credit Agreement, the entering into of Secured Hedge Agreements and the entering into of agreements in connection with Cash Management Obligations and, accordingly, desires to execute this Guaranty in order to satisfy the condition described in the preceding paragraph and to induce the Lenders to make Loans to the Borrower and issue, and/or participate in, Letters of Credit for the account of the Borrower, the Hedge Banks to enter into Secured Hedge Agreements and the Cash Management Banks to enter into agreements in connection with Cash Management Obligations;

          NOW, THEREFORE, in consideration of the foregoing and other benefits accruing to each Guarantor, the receipt and sufficiency of which are hereby acknowledged, each

Guarantor hereby makes the following representations and warranties to the Administrative Agent for the benefit of the Secured Creditors and hereby covenants and agrees with each other Guarantor and the Administrative Agent for the benefit of the Secured Creditors as follows:

          1. Each Guarantor, jointly and severally, irrevocably, absolutely and unconditionally guarantees as a primary obligor and not merely as surety to the Secured Creditors, the prompt and complete payment and performance when due (whether at the stated maturity, by required prepayment, declaration, acceleration, demand or otherwise) of all Obligations. Each Guarantor understands, agrees and confirms that this Guaranty is a guarantee of payment and not of collection, and that the Secured Creditors may enforce this Guaranty up to the full amount of the Obligations against such Guarantor without proceeding against any other Guarantor, the Borrower, or against any security for the Obligations, or under any other guaranty covering all or a portion of the Obligations.

          2. Additionally, each Guarantor, jointly and severally, unconditionally, absolutely and irrevocably, guarantees the payment of any and all Obligations of the Borrower to the Secured Creditors whether or not due or payable by the Borrower upon the occurrence of any of the events specified in Section 10A.05 of the Credit Agreement, and unconditionally, absolutely and irrevocably, jointly and severally, promises to pay such Obligations to the Secured Creditors, or order, on demand, in lawful money of the United States.

          3. The liability of each Guarantor hereunder is primary, absolute, joint and several, and unconditional and is exclusive and independent of any security for or other guaranty of the Obligations of the Borrower whether executed by such Guarantor, any other Guarantor, any other guarantor or by any other party, and the liability of each Guarantor hereunder shall not be affected or impaired by any circumstance or occurrence whatsoever, including, without limitation: (a) any direction as to application of payment by the Borrower or by any other party, (b) any other continuing or other guaranty, undertaking or maximum liability of a Guarantor or of any other party as to the Obligations of the Borrower, (c) any payment on or in reduction of any such other guaranty or undertaking, (d) any dissolution, termination or increase, decrease or change in personnel by the Borrower, (e) the failure of the Guarantor to receive any benefit from or as a result of its execution, delivery and performance of this Guaranty, (f) any payment made to any Secured Creditor on the Obligations which any Secured Creditor repays the Borrower or any Guarantor pursuant to court order in any bankruptcy, reorganization, arrangement, moratorium or other debtor relief proceeding, and each Guarantor waives any right to the deferral or modification of its obligations hereunder by reason of any such proceeding, (g) any action or inaction by the Secured Creditors as contemplated in Section 6 hereof or (h) any invalidity, rescission, irregularity or unenforceability of all or any part of the Obligations or of any security therefor.

          4. The obligations of each Guarantor hereunder are independent of the obligations of any other Guarantor, any other guarantor or the Borrower, and a separate action or actions may be brought and prosecuted against each Guarantor whether or not action is brought against any other Guarantor, any other guarantor or the Borrower and whether or not any other Guarantor, any other guarantor or the Borrower be joined in any such action or actions. Each Guarantor waives (to the fullest extent permitted by applicable law) the benefits of any statute of limitations affecting its liability hereunder or the enforcement thereof. Any payment by the

Borrower or other circumstance which operates to toll any statute of limitations as to the Borrower shall, to the maximum extent permitted by law, operate to toll the statute of limitations as to each Guarantor.

          5. Each Guarantor hereby waives (to the fullest extent permitted by applicable law) notice of acceptance of this Guaranty and notice of any liability to which it may apply, and waives promptness, diligence, presentment, demand of payment, protest, notice of dishonor or nonpayment of any such liabilities, suit or taking of other action by the Administrative Agent or any other Secured Creditor against, and any other notice to, any party liable thereon (including such Guarantor, any other Guarantor, any other guarantor, or the Borrower) and the Guarantor further hereby waives any and all notice of the creation, renewal, extension or accrual of any of the Obligations and notice or proof of reliance by any Secured Creditor upon this Guaranty, and the Obligations shall conclusively be deemed to have been created, contracted or incurred, or renewed, extended, amended, modified, supplemented or waived, in reliance upon this Guaranty.

          6. Any Secured Creditor may at any time and from time to time without the consent of, or notice to, any Guarantor, without incurring responsibility to such Guarantor, without impairing or releasing the obligations or liabilities of such Guarantor hereunder, upon or without any terms or conditions and in whole or in part:

     (a) change the manner, place or terms of payment of, and/or change, increase or extend the time of payment of, renew, increase, accelerate or alter, any of the Obligations (including, without limitation, any increase or decrease in the rate of interest thereon), any security therefor, or any liability incurred directly or indirectly in respect thereof, and the guaranty herein made shall apply to the Obligations as so changed, extended, increased, renewed or altered;

     (b) take and hold security for the payment of the Obligations and sell, exchange, release, surrender, realize upon or otherwise deal with in any manner and in any order any property by whomsoever at any time pledged or mortgaged to secure, or howsoever securing, the Obligations or any liabilities (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and/or any offset there against;

     (c) exercise or refrain from exercising any rights against the Borrower, any other Credit Party, any Subsidiary thereof, any other guarantor of the Borrower or others or otherwise act or refrain from acting;

     (d) release or substitute any one or more endorsers, Guarantors, other guarantors, the Borrower, or other obligors;

     (e) settle or compromise any of the Obligations, any security therefor or any liability (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and may subordinate the payment of all or any part thereof to the payment of any liability (whether due or not) of the Borrower to creditors of the Borrower other than the Secured Creditors;

     (f) apply any sums by whomsoever paid or howsoever realized to any liability or liabilities of the Borrower to the Secured Creditors regardless of what liabilities of the Borrower remain unpaid;

     (g) consent to or waive any breach of, or any act, omission or default under, any Secured Hedge Agreements, any documentation relating to any Cash Management Obligations, the Credit Documents or any of the instruments or agreements referred to therein, or otherwise amend, modify or supplement any Secured Hedge Agreements, any documentation relating to any Cash Management Obligations, the Credit Documents or any of such other instruments or agreements; and/or

     (h) take any other action or omit to take any other action which would, under otherwise applicable principles of common law, give rise to a legal or equitable discharge of such Guarantor from its liabilities under this Guaranty.

          7. No invalidity, illegality, irregularity or unenforceability of all or any part of the Obligations, the Credit Documents or any other agreement or instrument relating to the Obligations or of any security or guarantee therefor shall affect, impair or be a defense to this Guaranty (other than the defense of payment in full in cash of the Obligations), and this Guaranty shall be primary, absolute and unconditional notwithstanding the occurrence of any event or the existence of any other circumstances which might constitute a legal or equitable discharge of a surety or guarantor except payment in full in cash of the Obligations.

          8. This Guaranty is a continuing one and all liabilities to which it applies or may apply under the terms hereof shall be conclusively presumed to have been created in reliance hereon. No failure or delay on the part of any Secured Creditor in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein expressly specified are cumulative and not exclusive of any rights or remedies which any Secured Creditor would otherwise have. No notice to or demand on any Guarantor in any case shall entitle such Guarantor to any other further notice or demand in similar or other circumstances or constitute a waiver of the rights of any Secured Creditor to any other or further action in any circumstances without notice or demand. It is not necessary for any Secured Creditor to inquire into the capacity or powers of the Borrower or any of its Subsidiaries or the officers, directors, partners or agents acting or purporting to act on its or their behalf, and any indebtedness made or created in reliance upon the professed exercise of such powers shall be guaranteed hereunder.

          9. (a) Each Guarantor waives any right (except as shall be required by applicable Law and cannot be waived) to require the Secured Creditors to: (i) proceed against the Borrower, any other Guarantor, any other guarantor of the Obligations or any other party; (ii) proceed against or exhaust any security held from the Borrower, any other Guarantor, any other guarantor of the Obligations or any other party; or (iii) pursue any other remedy in the Secured Creditors’ power whatsoever. Each Guarantor waives any defense (other than a defense of payment) based on or arising out of any defense of the Borrower, any other Guarantor, any other guarantor of the Obligations or any other party other than payment in full of the Obligations, including, without limitation, any defense based on or arising out of the disability of the Borrower,

any other Guarantor, any other guarantor of the Obligations or any other party, or the unenforceability of the Obligations or any part thereof from any cause, or the cessation from any cause of the liability of the Borrower other than payment in full of the Obligations. The Secured Creditors may, at their election, foreclose on any collateral serving as security held by the Administrative Agent, the Collateral Agent or the other Secured Creditors by one or more judicial or nonjudicial sales, whether or not every aspect of any such sale is commercially reasonable (to the extent such sale is permitted by applicable Law), or exercise any other right or remedy the Secured Creditors may have against the Borrower or any other party, or any security, without affecting or impairing in any way the liability of any Guarantor hereunder except to the extent the Obligations have been paid.

          (b) Each Guarantor waives (except as shall be required by applicable statute or law and cannot be waived) all presentments, demands for performance, protests and notices, including, without limitation, notices of nonperformance, notices of protest, notices of dishonor, notices of acceptance of this Guaranty, and notices of the existence, creation or incurring of new or additional Obligations. Each Guarantor assumes all responsibility for being and keeping itself informed of the Borrower’s, and each other Guarantor’s, financial condition and assets, and of all other circumstances bearing upon the risk of nonpayment of the Obligations and the nature, scope and extent of the risks which such Guarantor assumes and incurs hereunder, and agrees that the Secured Creditors shall have no duty to advise any Guarantor of information known to them regarding any of the aforementioned circumstances or risks.

          10. The Secured Creditors agree (by their acceptance of the benefits of this Guaranty) that this Guaranty may be enforced only by the action of the Administrative Agent or the Collateral Agent and that no other Secured Creditor shall have any right individually to seek to enforce or to enforce this Guaranty or to realize upon the security to be granted by the Security Documents. The Secured Creditors further agree that this Guaranty may not be enforced against any director, officer, employee, partner, member or stockholder of any Guarantor (except to the extent such partner, member or stockholder is also a Guarantor hereunder). It is understood and agreed that the agreement in this Section 10 is among and solely for the benefit of the Secured Creditors.

          11. Each Guarantor hereby represents and warrants that the representations and warranties set forth in Section 7 of the Credit Agreement as they relate to such Guarantor and in the other Credit Documents to which such Guarantor is a party, each of which is hereby incorporated herein by reference, are true and correct in all material respects as of the Closing Date (except where such representations and warranties expressly relate to an earlier date, in which case such representations and warranties were true and correct in all material respects as of such earlier date), and the Collateral Agent and each other Secured Party shall be entitled to rely on each of them as if they were fully set forth herein.

          12. Each Guarantor covenants and agrees that on and after the Effective Date and until the date upon which the all Commitments under the Credit Agreement have been terminated and all Loans thereunder have been repaid in full, all Letters of Credit issued under the Credit Agreement have been terminated or cash collateralized on terms acceptable to the Issuing Lender or other arrangements acceptable to the Issuing Lender have been made pursuant to which the Issuing Lender has agreed such Letters of Credit are no longer outstanding for

purposes of the Credit Agreement, and all Obligations then due and payable have been paid in full (other than (x) contingent obligations not yet due and payable and (y) Cash Management Obligations or Obligations under Secured Hedge Agreements), such Guarantor will comply, and will cause each of its Subsidiaries to comply, with all of the applicable provisions, covenants and agreements contained in Sections 8 and 9 of the Credit Agreement, and will take, or will refrain from taking, as the case may be, all actions that are necessary to be taken or not taken so that no violation of any provision, covenant or agreement contained in Section 10A of the Credit Agreement, and so that no Default or Event of Default, is caused by the actions of such Guarantor or any of its Subsidiaries.

          13. Each Guarantor hereby jointly and severally agrees to pay all reasonable out-of-pocket costs and expenses of the Collateral Agent, the Administrative Agent and each Secured Creditor in connection with the enforcement of this Guaranty and the protection of the Secured Creditors’ rights hereunder and any amendment, waiver or consent relating hereto (including, in each case, without limitation, the reasonable fees and disbursements of counsel (including in-house counsel) employed by the Collateral Agent, the Administrative Agent and each Secured Creditor).

          14. This Guaranty shall be binding upon each Guarantor and its successors and assigns and shall inure to the benefit of the Secured Creditors and their successors and assigns.

          15. Neither this Guaranty nor any provision hereof may be changed, waived, discharged or terminated except with the written consent of each Guarantor directly affected thereby (it being understood that the addition or release of any Guarantor hereunder shall not constitute a change, waiver, discharge or termination affecting any Guarantor other than the Guarantor so added or released) and with the written consent of the Collateral Agent and any consents required by the Credit Agreement.

          16. In addition to any rights now or hereafter granted under applicable law (including, without limitation, Section 151 of the New York Debtor and Creditor Law) and not by way of limitation of any such rights, upon the occurrence and during the continuance of an Event of Default, each Secured Creditor is hereby authorized, at any time or from time to time, without notice to any Guarantor or to any other Person, any such notice being expressly waived, to set off and to appropriate and apply any and all deposits (general or special) and any other indebtedness at any time held or owing by such Secured Creditor to or for the credit or the account of such Guarantor, against and on account of the obligations and liabilities of such Guarantor to such Secured Creditor under this Guaranty, irrespective of whether or not such Secured Creditor shall have made any demand hereunder and although said obligations, liabilities, deposits or claims, Or any of them, shall be contingent or unmatured. Each Secured Creditor acknowledges and agrees that the provisions set forth in this Section 16 are subject to the sharing provisions set forth in Section 14.06 of the Credit Agreement.

          17. Except as otherwise specified herein, all notices, requests, demands or other communications pursuant hereto shall be in writing and given as provided in Section 14.03 of the Credit Agreement. All communications and notices hereunder to any Guarantor shall be

given to it in care of the Borrower at the Borrower’s address as provided in Section 14.03 of the Credit Agreement.

          18. If any claim is ever made upon any Secured Creditor for repayment or recovery of any amount or amounts received in payment or on account of any of the Obligations and any of the aforesaid payees repays all or part of said amount by reason of (i) any judgment, decree or order of any court or administrative body having jurisdiction over such payee or any of its property or (ii) any settlement or compromise of any such claim effected in good faith by such payee with any such claimant (including the Borrower), then and in such event each Guarantor agrees that any such judgment, decree, order, settlement or compromise shall be binding upon such Guarantor, notwithstanding any revocation hereof or the cancellation of any Note, any Secured Hedge Agreement, any documentation relating to any Cash Management Obligations or any other instrument evidencing any liability of the Borrower, and such Guarantor shall be and remain liable to the aforesaid payees hereunder for the amount so repaid or recovered to the same extent as if such amount had never originally been received by any such payee.

          19. (a) THIS GUARANTY AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HERETO SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAW OF THE STATE OF NEW YORK. Any legal action or proceeding with respect to this Guaranty or any other Credit Document to which any Guarantor is a party may be brought in the courts of the State of New York or of the United States of America for the Southern District of New York, in each case located within the County of New York, and, by execution and delivery of this Guaranty, each Guarantor hereby irrevocably accepts for itself and in respect of its property, generally and unconditionally, the non-exclusive jurisdiction of the aforesaid courts. Each party hereto hereby further irrevocably waives any claim that any such courts lack jurisdiction over such party, and agrees not to plead or claim, in any legal action or proceeding with respect to this Guaranty or any other Credit Document to which such Guarantor is a party brought in any of the aforesaid courts, that any such court lacks jurisdiction over such party. Each party hereto further irrevocably consents to the service of process in any action or proceeding arising out of or relating to any Credit Documents in the manner provided for notices (other than telecopier) in section 14.03 of the Credit Agreement. Nothing herein shall affect the right of any of the parties hereto to serve process in any other manner permitted by law or to commence legal proceedings or otherwise proceed against each Guarantor in any other jurisdiction.

          (b) Each party hereto hereby irrevocably waives (to the fullest extent permitted by applicable law) any objection which it may now or hereafter have to the laying of venue of any of the aforesaid actions or proceedings arising out of or in connection with this Guaranty or any other Credit Document to which such Guarantor is a party brought in the courts referred to in clause (a) above and hereby further irrevocably waives and agrees not to plead or claim in any such court that such action or proceeding brought in any such court has been brought in an inconvenient forum.

          (c) EACH GUARANTOR AND EACH SECURED CREDITOR (BY ITS ACCEPTANCE OF THE BENEFITS OF THIS GUARANTY) HEREBY IRREVOCABLY WAIVES ALL RIGHTS TO A TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS GUARANTY, THE OTHER

CREDIT DOCUMENTS TO WHICH SUCH GUARANTOR IS A PARTY OR THE TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY.

          20. (a) In the event that all of the capital stock or other Equity Interests of one or more Guarantors is sold or otherwise disposed of or liquidated pursuant to a transaction permitted under the Credit Agreement or is otherwise released at the direction of the Required Lenders (or all the Lenders if required by Section 14.12 of the Credit Agreement), such Guarantor shall, upon consummation of such sale, transfer or other disposition (except to the extent that such sale, transfer or disposition is to a Credit Party), be released from this Guaranty automatically and without further action and this Guaranty shall, as to each such Guarantor or Guarantors, terminate, and have no further force or effect (it being understood and agreed that the sale of one or more Persons that own, directly or indirectly, all of the capital stock or other Equity Interests of any Guarantor shall be deemed to be a sale of such Guarantor for the purposes of this Section 20).

          (b) In addition, one or more Guarantors may be released from the provisions of this Guaranty in accordance with the express provisions of the last sentence of Section 9.02 of the Credit Agreement and/or Section 9.12(b) of the Credit Agreement, and after such release, this Guaranty shall, as to each such Guarantor or Guarantors, terminate and have no further force or effect.

          21. To the extent that any Guarantor shall be required hereunder to pay a portion of the Obligations which shall exceed the greater of (i) the amount of the economic benefit actually received by such Guarantor from the incurrence of the Loans and the issuance of Letters of Credit under the Credit Agreement and the provision of Secured Hedge Agreements and Cash Management Obligations and (ii) the amount which such Guarantor would otherwise have paid if such Guarantor had paid the aggregate amount of the Obligations (excluding the amount thereof repaid by the Borrower and the other Guarantors) in the same proportion as such Guarantor’s net worth at the date enforcement hereunder is sought bears to the aggregate net worth of all the Guarantors at the date enforcement hereunder is sought (the “Contribution Percentage”), then such Guarantor shall have a right of contribution against each other Guarantor who has made payments in respect of the Obligations in an aggregate amount less than such other Guarantor’s Contribution Percentage of the aggregate payments made to and including the date enforcement hereunder is sought by all Guarantors in respect of the Obligations; provided that no Guarantor may take any action to enforce such right until the date upon which the all Commitments under the Credit Agreement have been terminated and all Loans thereunder have been repaid in full, all Letters of Credit issued under the Credit Agreement have been terminated or cash collateralized on terms acceptable to the Issuing Lender or other arrangements acceptable to the Issuing Lender have been made pursuant to which the Issuing Lender has agreed such Letters of Credit are no longer outstanding for purposes of the Credit Agreement, and all Obligations then due and payable have been paid in full, it being expressly recognized and agreed by all parties hereto that any Guarantor’s right of contribution arising pursuant to this Section 21 against any other Guarantor shall be expressly junior and subordinate to such other Guarantor’s obligations and liabilities in respect of the Obligations and any other obligations owing under this Guaranty. All parties hereto recognize and agree that, except for any right of contribution arising pursuant to this Section 21, each Guarantor who makes any payment in respect of the Obligations shall have no right of contribution or subrogation against any other Guarantor in respect of such payment. Each of

the Guarantors recognizes and acknowledges that the rights to contribution arising hereunder shall constitute an asset in favor of the party entitled to such contribution. In this connection, each Guarantor has the right to waive its contribution right against any Guarantor to the extent that after giving effect to such waiver such Guarantor would remain solvent, in the determination of the Required Lenders.

          22. (A) EACH GUARANTOR HEREBY ACKNOWLEDGES AND AFFIRMS THAT IT UNDERSTANDS THAT TO THE EXTENT THE OBLIGATIONS ARE SECURED BY REAL PROPERTY LOCATED IN THE STATE OF CALIFORNIA, SUCH GUARANTOR SHALL BE LIABLE FOR THE FULL AMOUNT OF THE LIABILITY HEREUNDER NOTWITHSTANDING FORECLOSURE ON SUCH REAL PROPERTY BY TRUSTEE SALE OR ANY OTHER REASON IMPAIRING SUCH GUARANTOR’S, THE COLLATERAL AGENT’S OR ANY SECURED CREDITORS’ RIGHT TO PROCEED AGAINST THE BORROWER OR ANY OTHER GUARANTOR OF THE OBLIGATIONS.

          (B) EACH GUARANTOR HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ALL RIGHTS AND BENEFITS UNDER SECTIONS 580a, 580b, 580d AND 726 OF THE CALIFORNIA CODE OF CIVIL PROCEDURE. EACH GUARANTOR HEREBY FURTHER WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, WITHOUT LIMITING THE GENERALITY OF THE FOREGOING OR ANY OTHER PROVISION HEREOF, ALL RIGHTS AND BENEFITS WHICH MIGHT OTHERWISE BE AVAILABLE TO SUCH GUARANTOR UNDER SECTIONS 2809, 2810, 2815, 2819, 2821, 2839, 2845, 2848, 2849, 2850, 2899 AND 3433 OF THE CALIFORNIA CIVIL CODE.

          (C) EACH GUARANTOR WAIVES ITS RIGHTS OF SUBROGATION AND REIMBURSEMENT AND ANY OTHER RIGHTS AND DEFENSES AVAILABLE TO SUCH GUARANTOR BY REASON OF SECTIONS 2787 TO 2855, INCLUSIVE, OF THE CALIFORNIA CIVIL CODE, INCLUDING, WITHOUT LIMITATION, (1) ANY DEFENSES SUCH GUARANTOR MAY HAVE TO THIS GUARANTY BY REASON OF AN ELECTION OF REMEDIES BY THE COLLATERAL AGENT OR THE SECURED CREDITORS AND (2) ANY RIGHTS OR DEFENSES SUCH GUARANTOR MAY HAVE BY REASON OF PROTECTION AFFORDED TO THE BORROWER PURSUANT TO THE ANTIDEFICIENCY OR OTHER LAWS OF CALIFORNIA LIMITING OR DISCHARGING THE BORROWER’S INDEBTEDNESS, INCLUDING, WITHOUT LIMITATION, SECTION 580a, 580b, 580d OR 726 OF THE CALIFORNIA CODE OF CIVIL PROCEDURE. IN FURTHERANCE OF SUCH PROVISIONS, EACH GUARANTOR HEREBY WAIVES ALL RIGHTS AND DEFENSES ARISING OUT OF AN ELECTION OF REMEDIES BY THE COLLATERAL AGENT OR THE SECURED CREDITORS, EVEN THOUGH THAT ELECTION OR REMEDIES, SUCH AS A NONJUDICIAL FORECLOSURE DESTROYS SUCH GUARANTOR’S RIGHTS OF SUBROGATION AND REIMBURSEMENT AGAINST THE BORROWER BY THE OPERATION OF SECTION 580d OF THE CALIFORNIA CODE OF CIVIL PROCEDURE OR OTHERWISE.

          (D) EACH GUARANTOR WARRANTS AND AGREES THAT EACH OF THE WAIVERS SET FORTH ABOVE IS MADE WITH FULL KNOWLEDGE OF ITS SIGNIFICANCE AND CONSEQUENCES AND THAT IF ANY OF SUCH WAIVERS ARE DETERMINED TO BE CONTRARY TO ANY APPLICABLE LAW OR PUBLIC POLICY, SUCH WAIVERS SHALL BE EFFECTIVE ONLY TO THE MAXIMUM EXTENT PERMITTED BY LAW.

          23. This Guaranty may be executed in any number of counterparts and by the different parties hereto on separate counterparts, each of which when so executed and delivered shall be an original, but all of which shall together constitute one and the same instrument. A set of counterparts executed by all the parties hereto shall be lodged with the Borrower and the Administrative Agent.

          24. All payments made by any Guarantor hereunder will be made without set-off, counterclaim or other defense and on the same basis as payments are made by the Borrower under Sections 4.03 and 4.04 of the Credit Agreement.

          25. It is understood and agreed that any Subsidiary of the Borrower that, after the date hereof, desires to become a Guarantor hereunder or is required to execute a counterpart of this Guaranty after the date hereof pursuant to the Credit Agreement shall become a Guarantor hereunder by (x) executing and delivering a counterpart hereof to the Administrative Agent or (y) executing a Joinder Agreement substantially in the form of Exhibit M to the Credit Agreement and delivering same to the Administrative Agent, in each case in form and substance reasonably satisfactory to the Administrative Agent and (y) taking all actions as specified in this Guaranty as would have been taken by such Guarantor had it been an original party to this Guaranty, in each case with all documents and actions required to be taken above to the reasonable satisfaction of the Administrative Agent.

          26. Each Guarantor and each Secured Creditor (by its acceptance of the benefits of this Guaranty) hereby confirms that it is its intention that this Guaranty not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Code, the Uniform Fraudulent Conveyance Act of any similar applicable Federal or state law. To effectuate the foregoing intention, each Guarantor and each Secured Creditor (by its acceptance of the benefits of this Guaranty) hereby irrevocably agrees that the Obligations guaranteed by such Guarantor shall be limited to such amount as will, after giving effect to such maximum amount and all other (contingent or otherwise) liabilities of such Guarantor that are relevant under such laws and after giving effect to any rights to contribution pursuant to any agreement providing for an equitable contribution among such Guarantor and the other Guarantors, result in the Obligations of such Guarantor in respect of such maximum amount not constituting a fraudulent transfer or conveyance.
