Section 7.2                                   Further Actions.  Each Debtor will, at its own expense, make, execute, endorse, acknowledge, file and/or deliver to the Purchaser from time to time such lists, descriptions and designations of its Collateral, warehouse receipts, receipts in the nature of warehouse receipts, bills of lading, documents of title, vouchers, invoices, schedules, confirmatory assignments, conveyances, transfer endorsements, powers of attorney, certificates, reports and other assurances or instruments and take such further steps relating to the Collateral and other property or rights covered by the security interest hereby granted, which the Purchaser deem reasonably appropriate or advisable to perfect, preserve or protect its security interest in the Collateral.

Section 7.3                                   Financing Statements; Etc.  Each Debtor agrees to execute and deliver to the Purchaser such further agreements, assignments, instruments, and documents, and to do all such other things, as the Purchaser may reasonably deem necessary or appropriate to assure the Purchaser its lien and Security Interest hereunder, including, without limitation, (i) such financing statements or other instruments and documents as the Purchaser may from time to time reasonably require to comply with the Uniform Commercial Code and any other applicable law, (ii) such agreements with respect to patents, trademarks, copyrights, and similar intellectual property rights as the Purchaser may from time to time reasonably require to comply with the filing requirements of the United States Patent and Trademark Office and the United States Copyright Office, and (iii) such control agreements with respect to Deposit Accounts, Investment Property, Letter of Credit Rights, and electronic Chattel Paper, and to cause the relevant depository institutions, financial intermediaries, and issuers to execute and deliver such control agreements, as the Purchaser may from time to time reasonably require.  Each Debtor hereby agrees that a carbon, photographic or other reproduction of this Agreement or any such financing statement is sufficient for filing as a financing statement by the Purchaser without notice thereof to such Debtor wherever the Purchaser in its sole discretion desires to file the same.  Each Debtor hereby authorizes the Purchaser to file any and all financing statements covering the Collateral or any part thereof as the Purchaser may require, including financing statements describing the Collateral as “all assets” or “all personal property” or words of like meaning.  In the event for any reason the law of any jurisdiction other than California becomes or is applicable to the Collateral or any part thereof, or to any of the Obligations, each Debtor agrees to execute and deliver all such agreements, assignments, instruments, and documents and to do all such other things as the Purchaser reasonably deems necessary or appropriate to preserve, protect, and enforce the security interest of the Purchaser under the law of such other jurisdiction.

GUARANTEE

Section 8.1                                   The Guarantee.  To induce the Purchaser to enter into the Purchase Agreement and in consideration of benefits expected to accrue to the Company by reason of the Purchase Agreement and for other good and valuable consideration, receipt of which is hereby

12

acknowledged, the Subsidiary hereby unconditionally and irrevocably guarantees jointly and severally to the Purchaser, the due and punctual payment of all present and future Obligations, in each case as and when the same shall become due and payable, whether at stated maturity, by acceleration, or otherwise, according to the terms hereof and thereof (including interest which, but for the filing of a petition in bankruptcy, would otherwise accrue on any such indebtedness, obligation, or liability).  In case of failure by the Company or other obligor punctually to pay any Obligations guaranteed hereby, the Subsidiary hereby unconditionally agrees to make such payment or to cause such payment to be made punctually as and when the same shall become due and payable, whether at stated maturity, by acceleration, or otherwise, and as if such payment were made by the Company or such obligor.

Section 8.2.                                Guarantee Unconditional.  The obligations of the Subsidiary under this Article 8 shall be unconditional and absolute and, without limiting the generality of the foregoing, shall not be released, discharged, or otherwise affected by:

(a)                                  any extension, renewal, settlement, compromise, waiver, or release in respect of any obligation of the Company or other obligor or of any other guarantor under this Agreement or the Purchase Agreement or by operation of law or otherwise;

(b)                                 any modification or amendment of or supplement to this Agreement or the Purchase Agreement;

(c)                                  any change in the corporate existence, structure, or ownership of, or any insolvency, bankruptcy, reorganization, or other similar proceeding affecting, the Company or other obligor, any other guarantor, or any of their respective assets, or any resulting release or discharge of any obligation of the Company or other obligor or of any other guarantor contained in this Agreement or the Purchase Agreement;

(d)                                 the existence of any claim, set-off, or other rights which the Company or other obligor or any other guarantor may have at any time against the Purchaser or any other person or entity, whether or not arising in connection herewith;

(e)                                  any failure to assert, or any assertion of, any claim or demand or any exercise of, or failure to exercise, any rights or remedies against the Company or other obligor, any other guarantor, or any other person or entity or property;

(f)                                    any application of any sums by whomsoever paid or howsoever realized to any obligation of the Company or other obligor, regardless of what obligations of the Company or other obligor remain unpaid;

(g)                                 any invalidity or unenforceability relating to or against the Company or other obligor or any other guarantor for any reason of this Agreement or of the Purchase Agreement or any provision of applicable law or regulation purporting to prohibit the payment by the Company or other obligor or any other guarantor of the principal of or interest on the Junior Note or Obligations or any other amount payable under the Purchase Agreement; or

13

(h)                                 any other act or omission to act or delay of any kind by the Purchaser, or any other person or entity or any other circumstance whatsoever that might, but for the provisions of this paragraph, constitute a legal or equitable discharge of the obligations of the Subsidiary under this Article 8.

Section 8.3.                                Discharge Only upon Payment in Full; Reinstatement in Certain Circumstances.  The Subsidiary’s obligations under this Article 8 shall remain in full force and effect until the Purchase Agreement is terminated and the principal of and interest on the Junior Note and all other amounts payable by the Company under the Purchase Agreement and this Agreement shall have been paid in full.  If at any time any payment of the principal of or interest on the Junior Note or any Obligation or any other amount payable by the Company or other obligor or the Subsidiary under the Purchase Agreement or this Agreement is rescinded or must be otherwise restored or returned upon the insolvency, bankruptcy, or reorganization of the Company or other obligor or of any guarantor, or otherwise, the Subsidiary’s obligations under this Article 8 with respect to such payment shall be reinstated at such time as though such payment had become due but had not been made at such time.

Section 8.4                                   Subrogation.  The Subsidiary agrees it will not exercise any rights which it may acquire by way of subrogation by any payment made hereunder, or otherwise, until all the Obligations shall have been paid in full subsequent to the termination of all the Purchase Agreement.  If any amount shall be paid to the Subsidiary on account of such subrogation rights at any time prior to the later of (x) the payment in full of the Obligations and all other amounts payable by the Company hereunder and the Purchase Agreement and (y) the termination of the Purchase Agreement, such amount shall be held in trust for the benefit of the Purchaser and shall forthwith be paid to the Purchaser or be credited and applied upon the Obligations.

Section 8.5                                   Waivers.  The Subsidiary irrevocably waives acceptance hereof, presentment, demand, protest, and any notice not provided for herein, together with the rights, protections and defenses accorded by Sections 2787 through 2855 of the California Civil Code which provide protections for and limitations on the obligations of a guarantor such as, but not limited to, limitations that provide (i) in certain circumstances, that a notice be given to the guarantor of any default by the debtor or obligor which may result in liability to the guarantor, (ii) that the obligations of a guarantor cannot be greater in amount or more burdensome than that of the obligor; (iii) that the guarantor will have the same defenses to liability as the obligor, other than defenses arising from the personal disability of the obligor; (iv) that a guarantor will be exonerated from liability, by any act of the creditor taken without the guarantor’s consent, which alters the original obligations of the obligor or impairs or suspends any remedies or rights of the creditor against the obligor or security for the guaranteed obligation; (v) that the creditor’s acceptance of anything in partial satisfaction of the guaranteed obligation also reduces the obligation of the guarantor to the same extent; and (vi) that a guarantor may require the creditor to proceed against the obligor or security held by the creditor or to pursue other remedies within the power of the creditor which cannot be pursued by the guarantor before proceeding against the guarantor, as well as any requirement that at any time any action be taken by the Purchaser, or any other person or entity against the Company or other obligor, another guarantor, or any other person or entity.

14

Section 8.6                                   Limit on Recovery.  Notwithstanding any other provision hereof, the right of recovery against the Subsidiary under this Article 8 shall not exceed $1.00 less than the lowest amount which would render such Subsidiary’s obligations under this Article 8 void or voidable under applicable law, including, without limitation, fraudulent conveyance law.

Section 8.7                                   Stay of Acceleration.  If acceleration of the time for payment of any amount payable by the Company or other obligor under this Agreement or the Purchase Agreement, is stayed upon the insolvency, bankruptcy or reorganization of the Company or such obligor, all such amounts otherwise subject to acceleration under the terms of this Agreement or the Purchase Agreement, shall nonetheless be payable by the Subsidiary hereunder forthwith on demand by the Purchaser.

Section 8.8                                   Benefit to Subsidiary.  The Company and the Subsidiary are engaged in related businesses and integrated to such an extent that the financial strength and flexibility of the Company has a direct impact on the success of the Subsidiary.  The Subsidiary will derive substantial direct and indirect benefit from the extensions of credit hereunder.

Section 8.9                                   Subsidiary Covenants.  The Subsidiary shall take such action as the Company is required by the Purchase Agreement or this Agreement to cause the Subsidiary to take, and shall refrain from taking such action as the Company is required by the Purchase Agreement or this Agreement to prohibit the Subsidiary from taking.

ARTICLE 9

REMEDIES UPON OCCURRENCE OF EVENT OF DEFAULT

Section 9.1                                   Remedies; Obtaining the Collateral Upon Default.  Each Debtor agrees that, if an Event of Default shall have occurred and be continuing, then and in every such case, the Purchaser, in addition to any rights now or hereafter existing under applicable law, shall have all rights as a secured creditor under the UCC in all relevant jurisdictions subject to the subordination thereof pursuant to Section 11.10 hereof, and may:

(a)                                  personally, or by agents or attorneys, immediately take possession of the Collateral or any part thereof, from the Debtors or any other Person who then has possession of any part thereof with or without notice or process of law, and for that purpose may enter upon such Debtor’s premises where any of the Collateral is located and remove the same and use in connection with such removal any and all services, supplies, aids and other facilities of such Debtor;

(b)                                 instruct the obligor or obligors on any agreement, instrument or other obligation (including, without limitation, the Accounts) constituting the Collateral to make any payment required by the terms of such agreement, instrument or other obligation directly to the Purchaser;

(c)                                  withdraw all monies, securities and instruments in the Cash Collateral Account and/or in any other cash collateral account for application to the Obligations in accordance with Section 9.4 hereof;

15

(d)                                 sell, assign or otherwise liquidate any or all of the Collateral or any part thereof in accordance with Section 9.2 hereof, or direct such Debtor to sell, assign or otherwise liquidate any or all of the Collateral or any part thereof, and, in each case, take possession of the proceeds of any such sale or liquidation;

(e)                                  take possession of the Collateral or any part thereof, by directing the Debtors in writing to deliver the same to the Purchaser at any place or places reasonably designated by the Purchaser, in which event such Debtor shall at its own expense:

(i)                                     forthwith cause the same to be moved to the place or places so designated by the Purchaser and there delivered to the Purchaser;

(ii)                                  store and keep any Collateral so delivered to the Purchaser at such place or places pending further action by the Purchaser as provided in Section 9.2 hereof; and

(iii)                               while the Collateral shall be so stored and kept, provide such guards and maintenance services as shall be necessary to protect the same and to preserve and maintain them in good condition; and

(f)                                    license or sublicense, whether on an exclusive or nonexclusive basis, any Marks, Patents or Copyrights included in the Collateral for such term and on such conditions and in such manner as the Purchaser shall in its commercially reasonable judgment determine;

it being understood that each Debtor’s obligation so to deliver the Collateral is of the essence of this Agreement and that, accordingly, upon application to a court of equity having jurisdiction, the Purchaser shall be entitled to a decree requiring specific performance by each Debtor of said obligation.

Section 9.2                                   Remedies: Disposition of the Collateral.  Any Collateral repossessed by the Purchaser under or pursuant to Section 9.1 hereof and any other Collateral whether or not so repossessed by the Purchaser, may be sold, assigned, leased or otherwise disposed of under one or more contracts or as an entirety, and without the necessity of gathering at the place of sale the property to be sold, and in general in such manner, at such time or times, at such place or places and on such terms as the Purchaser may, in compliance with any mandatory requirements of applicable law, determine to be commercially reasonable.  Any of the Collateral may be sold, leased or otherwise disposed of, in the condition in which the same existed when taken by the Purchaser or after any overhaul or repair at the expense of each Debtor which the Purchaser shall determine to be commercially reasonable.  Any such disposition which shall be a private sale or other private proceedings permitted by such requirements shall be made upon not less than 10 days’ written notice to each Debtor specifying the time at which such disposition is to be made and the intended sale price or other consideration therefor, and shall be subject, for the 10 days after the giving of such notice, to the right of each Debtor or any nominee of each Debtor to acquire the Collateral involved at a price or for such other consideration at least equal to the intended sale price or other consideration so specified, but in no event in an amount greater than

16

the Obligations then outstanding and provision for any contingent Obligations reasonably acceptable to the Purchaser.  Any such disposition which shall be a public sale permitted by such requirements shall be made upon not less than 10 days’ written notice to each Debtor specifying the time and place of such sale and, in the absence of applicable requirements of law, shall be by public auction (which may, at the Purchaser’s option, be subject to reserve), after publication of notice of such auction not less than 10 days prior thereto in two newspapers in general circulation in Orange County, California.  To the extent permitted by any such requirement of law, the Purchaser may bid for and become the purchaser of the Collateral or any item thereof, offered for sale in accordance with this Section without accountability to the Debtors.  If, under mandatory requirements of applicable law, the Purchaser shall be required to make disposition of the Collateral within a period of time which does not permit the giving of notice to the Debtors as hereinabove specified, the Purchaser need give the Debtors only such notice of disposition as shall be reasonably practicable in view of such mandatory requirements of applicable law.

Section 9.3                                   Waiver of Claims.  Except as otherwise provided in this Agreement or prohibited by applicable law, (a) THE DEBTORS HEREBY WAIVE, TO THE EXTENT PERMITTED BY APPLICABLE LAW, NOTICE AND JUDICIAL HEARING IN CONNECTION WITH THE PURCHASER’S TAKING POSSESSION OR THE PURCHASER’S DISPOSITION OF ANY OF THE COLLATERAL, INCLUDING, WITHOUT LIMITATION, ANY AND ALL PRIOR NOTICE AND HEARING FOR ANY PREJUDGMENT REMEDY OR REMEDIES AND ANY SUCH RIGHT WHICH SUCH DEBTOR WOULD OTHERWISE HAVE UNDER THE CONSTITUTION OR ANY STATUTE OF THE UNITED STATES OR OF ANY STATE, (b) the Debtors hereby further waive, to the extent permitted by law:

(i)                                     all damages occasioned by such taking of possession except any damages which are determined by a final, non-appealable court order to have been caused by the Purchaser’s gross negligence or willful misconduct; and

(ii)                                  all other requirements as to the time, place and terms of sale or other requirements with respect to the enforcement of the Purchaser’s rights hereunder; and

(iii)                               all rights of redemption, appraisement, valuation, stay, extension or moratorium now or hereafter in force under any applicable law in order to prevent or delay the enforcement of this Agreement or the absolute sale of the Collateral or any portion thereof, and each Debtor, for itself and all who may claim under it, insofar as it or they now or hereafter lawfully may, hereby waives the benefit of all such laws.

Any sale of, or the grant of options to purchase, or any other realization upon, any Collateral shall operate to divest all right, title, interest, claim and demand, either at law or in equity, of the Debtors therein and thereto, and shall be a perpetual bar both at law and in equity against the Debtors and against any and all persons or entities claiming or attempting to claim the Collateral so sold, optioned or realized upon, or any part thereof, from, through and under the Debtors.

17

Section 9.4                                   Application of Proceeds.

(a)                                  All monies collected by the Purchaser upon any sale or other disposition of the Collateral, together with all other moneys received by the Purchaser hereunder, shall be applied to the payment of the Obligations.

(b)                                 It is understood and agreed that each Debtor shall remain liable to the extent of any deficiency between the amount of the proceeds of the Collateral hereunder and the aggregate amount of the Obligations.

Section 9.5                                   Remedies Cumulative.  Each and every right, power and remedy hereby specifically given to the Purchaser shall be in addition to every other right, power and remedy specifically given under this Agreement, the Purchase Agreement or now or hereafter existing at law, in equity or by statute and each and every right, power and remedy whether specifically herein given or otherwise existing may be exercised from time to time or simultaneously and as often and in such order as may be deemed expedient by the Purchaser.  All such rights, powers and remedies shall be cumulative and the exercise or the beginning of the exercise of one shall not be deemed a waiver of the right to exercise any other or others.  No delay or omission of the Purchaser in the exercise of any such right, power or remedy and no renewal or extension of any of the Obligations shall impair any such right, power or remedy or shall be construed to be a waiver of any Default or Event of Default or an acquiescence therein.  No notice to or demand on the Debtors in any case shall entitle it to any other or further notice or demand in similar or other circumstances or constitute a waiver of any of the rights of the Purchaser to any other or further action in any circumstances without notice or demand.  In the event that the Purchaser shall bring any suit to enforce any of its rights hereunder and shall be entitled to judgment, then in such suit the Purchaser may recover reasonable expenses, including reasonable attorneys’ fees, and the amounts thereof shall be included in such judgment.

Section 9.6                                   Discontinuance of Proceedings.  In case the Purchaser shall have instituted any proceeding to enforce any right, power or remedy under this Agreement by foreclosure, sale, entry or otherwise, and such proceeding shall have been discontinued or abandoned for any reason or shall have been determined adversely to the Purchaser, then and in every such case the Debtors, the Purchaser and each holder of any of the Obligations shall be restored to their former positions and rights hereunder with respect to the Collateral subject to the Security Interest created under this Agreement, and all rights, remedies and powers of the Purchaser shall continue as if no such proceeding had been instituted.

Section 9.7                                   Attorney-in-Fact.  Without limiting any rights or powers granted by this Agreement to the Purchaser while no Event of Default has occurred and is continuing, upon the occurrence and during the continuance of any Event of Default the Purchaser is hereby appointed the attorney-in-fact of the Debtors for the purpose of carrying out the provisions of this Agreement and taking any action and executing any instruments which may be reasonably required to accomplish the purposes hereof, which appointment as attorney-in-fact is irrevocable and coupled with an interest.  Without limiting the generality of the foregoing, the Purchaser shall have the right and power to receive, endorse and collect all checks made payable to the

18

order of the Debtors representing any dividend, payment or other distribution in respect of the Collateral or any part thereof and to give full discharge for the same.
