Item 1.01               Entry into a Material Definitive Agreement

Item 2.03.              Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement

                On December 28, 2007, Willdan Group, Inc., (the “Company”), entered into a Credit Agreement (the “Credit Agreement”) and a related Revolving Line of Credit Note (the “Note”), Security Agreement: Equipment and Continuing Security Agreement: Rights to Payment and Inventory (collectively with the Credit Agreement and the Note, the “Agreements”) with Wells Fargo Bank, National Association (“Wells Fargo”). 

                Under the terms of the Credit Agreement, the Company can borrow up to $10.0 million from time to time up to and until January 1, 2010.  Loans made under the revolving line of credit will accrue interest at either (i) the floating rate of 0.50% below the Prime Rate in effect from time to time or (ii) the fixed rate of 1.25% above LIBOR, at the election of the Company.  The interest rate is subject to adjustment based on changes in the Company’s ratio of Total Funded Debt to EBITDA (as defined in the Credit Agreement).  Upon a default, the interest rate will be increased by a default rate margin of 4.00%.  Upon the occurrence of an event of default under the Credit Agreement, Wells Fargo has the option to make all indebtedness then owed by the Company under the Agreements immediately due and payable.  The revolving line of credit matures on January 31, 2010. 

                Borrowings under the Credit Agreement are secured by all accounts receivable and other rights to payment, general intangibles, inventory and equipment of the Company and its subsidiaries.  Each subsidiary of the Company (except Public Agency Resources) has signed an unconditional guaranty of the Company’s obligations under the Agreements.  The Credit Agreement also contains customary representations and affirmative covenants, including covenants to maintain a minimum tangible net worth, a minimum net income, a minimum asset coverage ratio and a maximum ratio of total funded debt to EBITDA (each ratio as specifically defined in the Credit Agreement).  The Credit Agreement also includes customary negative covenants, including a covenant that prohibits the incurrence of additional indebtedness by the Company or its subsidiaries other than purchase money indebtedness not to exceed $2.0 million and indebtedness existing on the date of the Credit Agreement, and a covenant that prohibits payment of dividends on the Company’s stock.  In addition, the Credit Agreement includes customary defaults for a credit facility.

                The foregoing summary description of the Agreements does not purport to be complete and is qualified in its entirety by reference to the Agreements attached hereto as Exhibits 10.1, 10.2, 10.3 and 10.4.

Item 1.02               Termination of a Material Definitive Agreement

                The Company terminated its Business Loan Agreement (Asset Based), Promissory Note and Commercial Security Agreement (the “Prior Agreement”) with Orange County Business Bank on December 31, 2007.  The Company terminated the Prior Agreement in connection with its entering into of the new revolving credit facility with Wells Fargo described above under Item 1.01 – Entry into a Material Definitive Agreement.  The Company paid no fees or penalties as a result of terminating the Prior Agreement with Orange County Business Bank.

                Under the Prior Agreement, the Company could borrow up to $8.0 million under a revolving line of credit.  The Company had the right to convert up to $2.0 million of the revolving line of credit to two term loans under specified circumstances involving the start up of a new division and/or business unit and the acquisition of other companies.  Loans made under the revolving line of credit accrued interest at the rate of 0.25% over the current Wall Street Journal Prime Rate.  Upon a default, the interest rate would have increased by a default rate margin of 6.00%.  Upon the occurrence of an event of default under the loan agreement, Orange County Business Bank had the option to make all indebtedness then owed by the Company under Prior Agreement immediately due and payable.

                Borrowings under the Primary Agreement were secured by substantially all of the Company’s and its subsidiaries’ tangible and intangible assets.  Each of the Company’s subsidiaries, except Public Agency Resources, had signed an unconditional guaranty of its obligations under the Prior Agreement.  The Prior Agreement also contained customary representations, affirmative and negative covenants and defaults for a credit facility, including covenants to maintain a minimum tangible net worth, a minimum ratio of current assets to current liabilities and a minimum ratio of debt service coverage.  The Prior Agreement also prohibited the payment of dividends on the Company’s common stock, other than dividends payable in the Company’s common stock, without the consent of Orange County Business Bank.

Borrower’s obligation to repay advances under the Line of Credit shall be evidenced by a promissory note dated as of December 28, 2007 (“Line of Credit Note”), all terms of which are incorporated herein by this reference.

(b)                        Letter of Credit Subfeature. As a subfeature under the Line of Credit, Bank agrees from time to time during the term thereof to issue or cause an affiliate to issue standby letters of credit for the account of Borrower (each, a “Letter of Credit” and collectively, “Letters of Credit”); provided however, that the aggregate undrawn amount of all outstanding Letters of Credit shall not at any time exceed Five Million Dollars ($5,000,000.00). The form and substance of each Letter of Credit shall be subject to approval by Bank, in its sole discretion. No Letter of Credit shall have an expiration date subsequent to the maturity date of the Line of Credit. The undrawn amount of all Letters of Credit shall be reserved under the Line of Credit and shall not be available for borrowings thereunder. Each Letter of Credit shall be subject to the additional terms and conditions of the Letter of Credit agreements, applications and any related documents required by Bank in connection with the issuance thereof. Each drawing paid under a Letter of Credit shall be deemed an advance under the Line of Credit and shall be repaid by Borrower in accordance with the terms and conditions of this Agreement applicable to such advances; provided however, that if advances under the Line of Credit are not available, for any reason, at the time any drawing is paid, then Borrower shall immediately pay to Bank the full amount drawn, together with interest thereon from the date such drawing is paid to the date such amount is fully repaid by Borrower, at the rate of interest applicable to advances under the Line of Credit. In such event Borrower agrees that Bank, in its sole discretion, may debit any account maintained by Borrower with Bank for the amount of any such drawing.

(c)                         Borrowing and Repayment. Borrower may from time to time during the term of the Line of Credit borrow, partially or wholly repay its outstanding borrowings, and reborrow, subject to all of the limitations, terms and conditions contained herein or in the Line of Credit Note; provided however, that the total outstanding borrowings under the Line of Credit shall not at any time exceed the maximum principal amount available thereunder, as set forth above.

Should there be insufficient funds in any such deposit account to pay all such sums when due, the full amount of such deficiency shall be immediately due and payable by Borrower.

SECTION 7.10.                     GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the laws of the State of California.

SECTION 7.11.                     ARBITRATION.

(a)                     Arbitration. The parties hereto agree, upon demand by any party, to submit to binding arbitration all claims, disputes and controversies between or among them (and their respective employees, officers, directors, attorneys, and other agents), whether in tort, contract or otherwise in any way arising out of or relating to (i) any credit subject hereto, or any of the Loan Documents, and their negotiation, execution, collateralization, administration, repayment, modification, extension, substitution, formation, inducement, enforcement, default or termination; or (ii) requests for additional credit.

(b)                    Governing Rules. Any arbitration proceeding will (i) proceed in a location in California selected by the American Arbitration Association (“AAA”); (ii) be governed by the Federal Arbitration Act (Title 9 of the United States Code), notwithstanding any conflicting choice of law provision in any of the documents between the parties; and (iii) be conducted by the AAA, or such other administrator as the parties shall mutually agree upon, in accordance with the AAA’s commercial dispute resolution procedures, unless the claim or counterclaim is at least $1,000,000.00 exclusive of claimed interest, arbitration fees and costs in which case the arbitration shall be conducted in accordance with the AAA’s optional procedures for large, complex commercial disputes (the commercial dispute resolution procedures or the optional procedures for large, complex commercial disputes to be referred to herein, as applicable, as the “Rules”). If there is any inconsistency between the terms hereof and the Rules, the terms and procedures set forth herein shall control. Any party who fails or refuses to submit to arbitration following a demand by any other party shall bear all costs and expenses incurred by such other party in compelling arbitration of any dispute. Nothing contained herein shall be deemed to be a waiver by any party that is a bank of the protections afforded to it under 12 U.S.C. §91 or any similar applicable state law.

(c)                     No Waiver of Provisional Remedies. Self-Help and Foreclosure. The arbitration requirement does not limit the right of any party to (i) foreclose against real or personal property collateral; (ii) exercise self-help remedies relating to collateral or proceeds of collateral such as setoff or repossession; or (iii) obtain provisional or ancillary remedies such as replevin, injunctive relief, attachment or the appointment of a receiver, before during or after the pendency of any arbitration proceeding. This exclusion does not constitute a waiver of the right or obligation of any party to submit any dispute to arbitration or reference hereunder, including those arising from the exercise of the actions detailed in sections (i), (ii) and (iii) of this paragraph.

14

(d)                    Arbitrator Qualifications and Powers. Any arbitration proceeding in which the amount in controversy is $5,000,000.00 or less will be decided by a single arbitrator selected according to the Rules, and who shall not render an award of greater than $5,000,000.00. Any dispute in which the amount in controversy exceeds $5,000,000.00 shall be decided by majority vote of a panel of three arbitrators; provided however, that all three arbitrators must actively participate in all hearings and deliberations. The arbitrator will be a neutral attorney licensed in the State of California or a neutral retired judge of the state or federal judiciary of California, in either case with a minimum of ten years experience in the substantive law applicable to the subject matter of the dispute to be arbitrated. The arbitrator will determine whether or not an issue is arbitratable and will give effect to the statutes of limitation in determining any claim. In any arbitration proceeding the arbitrator will decide (by documents only or with a hearing at the arbitrator’s discretion) any pre-hearing motions which are similar to motions to dismiss for failure to state a claim or motions for summary adjudication. The arbitrator shall resolve all disputes in accordance with the substantive law of California and may grant any remedy or relief that a court of such state could order or grant within the scope hereof and such ancillary relief as is necessary to make effective any award. The arbitrator shall also have the power to award recovery of all costs and fees, to impose sanctions and to take such other action as the arbitrator deems necessary to the same extent a judge could pursuant to the Federal Rules of Civil Procedure, the California Rules of Civil Procedure or other applicable law. Judgment upon the award rendered by the arbitrator may be entered in any court having jurisdiction. The institution and maintenance of an action for judicial relief or pursuit of a provisional or ancillary remedy shall not constitute a waiver of the right of any party, including the plaintiff, to submit the controversy or claim to arbitration if any other party contests such action for judicial relief.

(e)                       Discovery. In any arbitration proceeding, discovery will be permitted in accordance with the Rules. All discovery shall be expressly limited to matters directly relevant to the dispute being arbitrated and must be completed no later than 20 days before the hearing date. Any requests for an extension of the discovery periods, or any discovery disputes, will be subject to final determination by the arbitrator upon a showing that the request for discovery is essential for the party’s presentation and that no alternative means for obtaining information is available.

(f)                         Class Proceedings and Consolidations. No party hereto shall be entitled to join or consolidate disputes by or against others in any arbitration, except parties who have executed any Loan Document, or to include in any arbitration any dispute as a representative or member of a class, or to act in any arbitration in the interest of the general public or in a private attorney general capacity.

(g)                      Payment Of Arbitration Costs And Fees. The arbitrator shall award all costs and expenses of the arbitration proceeding.

(h)                      Real Property Collateral; Judicial Reference. Notwithstanding anything herein to the contrary, no dispute shall be submitted to arbitration if the dispute concerns indebtedness secured directly or indirectly, in whole or in part, by any real property unless (i) the holder of the mortgage, lien or security interest specifically elects in writing to proceed with the arbitration, or (ii) all parties to the arbitration waive any rights or benefits that might accrue to them by virtue of the single action rule statute of California, thereby agreeing that all indebtedness and obligations of the parties, and all mortgages, liens and security interests securing such indebtedness and obligations, shall remain fully valid and enforceable. If any such dispute is not submitted to arbitration, the dispute shall be referred to a referee in accordance with California Code of Civil Procedure Section 638 et seq., and this general reference agreement is intended to be specifically enforceable in accordance with said Section 638. A referee with the qualifications required herein for arbitrators shall be selected pursuant to the AAA’s selection procedures. Judgment upon the decision rendered by a referee shall be entered in the court in which such proceeding was commenced in accordance with California Code of Civil Procedure Sections 644 and 645.

15

(i)                          Miscellaneous. To the maximum extent practicable, the AAA, the arbitrators and the parties shall take all action required to conclude any arbitration proceeding within 180 days of the filing of the dispute with the AAA. No arbitrator or other party to an arbitration proceeding may disclose the existence, content or results thereof, except for disclosures of information by a party required in the ordinary course of its business or by applicable law or regulation. If more than one agreement for arbitration by or between the parties potentially applies to a dispute, the arbitration provision most directly related to the Loan Documents or the subject matter of the dispute shall control. This arbitration provision shall survive termination, amendment or expiration of any of the Loan Documents or any relationship between the parties.

(j)                          Small Claims Court. Notwithstanding anything herein to the contrary, each party retains the right to pursue in Small Claims Court any dispute within that court’s jurisdiction. Further, this arbitration provision shall apply only to disputes in which either party seeks to recover an amount of money (excluding attorneys’ fees and costs) that exceeds the jurisdictional limit of the Small Claims Court.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed as of the day and year first written above.

Exhibit 10.2

FOR VALUE RECEIVED, the undersigned Willdan Group, Inc. (“Borrower”) promises to pay to the order of WELLS FARGO BANK, NATIONAL ASSOCIATION (“Bank”) at its office at San Gabriel Valley RCBO, 1000 Lakes Drive, Suite #250, West Covina, CA 91790, or at such other place as the holder hereof may designate, in lawful money of the United States of America and in immediately available funds, the principal sum of $10,000,000.00, or so much thereof as may be advanced and be outstanding, with interest thereon, to be computed on each advance from the date of its disbursement as set forth herein.

1.                         DEFINITIONS:

As used herein, the following terms shall have the meanings set forth after each, and any other term defined in this Note shall have the meaning set forth at the place defined:

1.1                     “Business Day” means any day except a Saturday, Sunday or any other day on which commercial banks in California are authorized or required by law to close.

1.2                     “Fixed Rate Term” means a period commencing on a Business Day and continuing for 1, 2 or 3 months, as designated by Borrower, during which all or a portion of the outstanding principal balance of this Note bears interest determined in relation to LIBOR; provided however, that no Fixed Rate Term may be selected for a principal amount less than $100,000.00; and provided further, that no Fixed Rate Term shall extend beyond the scheduled maturity date hereof. If any Fixed Rate Term would end on a day which is not a Business Day, then such Fixed Rate Term shall be extended to the next succeeding Business Day.

1.3                     “LIBOR” means the rate per annum (rounded upward, if necessary, to the nearest whole 1/8 of 1%) determined by dividing Base LIBOR by a percentage equal to 100% less any LIBOR Reserve Percentage.

(a)                       “Base LIBOR” means the rate per annum for United States dollar deposits quoted by Bank as the Inter-Bank Market Offered Rate, with the understanding that such rate is quoted by Bank for the purpose of calculating effective rates of interest for loans making reference thereto, on the first day of a Fixed Rate Term for delivery of funds on said date for a period of time approximately equal to the number of days in such Fixed Rate Term and in an amount approximately equal to the principal amount to which such Fixed Rate Term applies. Borrower understands and agrees that Bank may base its quotation of the Inter-Bank Market Offered Rate upon such offers or other market indicators of the Inter-Bank Market as Bank in its discretion deems appropriate including, but not limited to, the rate offered for U.S. dollar deposits on the London Inter-Bank Market.

(b)                      “LIBOR Reserve Percentage” means the reserve percentage prescribed by the Board of Governors of the Federal Reserve System (or any successor) for “Eurocurrency Liabilities” (as defined in Regulation D of the Federal Reserve Board, as amended), adjusted by Bank for expected changes in such reserve percentage during the applicable Fixed Rate Term.

1.4                     “Prime Rate” means at any time the rate of interest most recently announced within Bank at its principal office as its Prime Rate, with the understanding that the Prime Rate is one of Bank’s base rates and serves as the basis upon which effective rates of interest are calculated for those loans making reference thereto, and is evidenced by the recording thereof after its announcement in such internal publication or publications as Bank may designate.

1

2.                         INTEREST:

2.1                     Interest. The outstanding principal balance of this Note shall bear interest (computed on the basis of a 360-day year, actual days elapsed) either (a) at a fluctuating rate per annum 0.50000% below the Prime Rate in effect from time to time, or (b) at a fixed rate per annum determined by Bank to be 1.25000% above LIBOR in effect on the first day of the applicable Fixed Rate Term. When interest is determined in relation to the Prime Rate, each change in the rate of interest hereunder shall become effective on the date each Prime Rate change is announced within Bank. With respect to each LIBOR selection option selected hereunder, Bank is hereby authorized to note the date, principal amount, interest rate and Fixed Rate Term applicable thereto and any payments made thereon on Bank’s books and records (either manually or by electronic entry) and/or on any schedule attached to this Note, which notations shall be prima facie evidence of the accuracy of the information noted.

2.2                     Selection of Interest Rate Options. At any time any portion of this Note bears interest determined in relation to LIBOR, it may be continued by Borrower at the end of the Fixed Rate Term applicable thereto so that all or a portion thereof bears interest determined in relation to the Prime Rate or to LIBOR for a new Fixed Rate Term designated by Borrower. At any time any portion of this Note bears interest determined in relation to the Prime Rate, Borrower may convert all or a portion thereof so that it bears interest determined in relation to LIBOR for a Fixed Rate Term designated by Borrower. At such time as Borrower requests an advance hereunder or wishes to select a LIBOR option for all or a portion of the outstanding principal balance hereof, and at the end of each Fixed Rate Term, Borrower shall give Bank notice specifying: (a) the interest rate option selected by Borrower: (b) the principal amount subject thereto: and (c) for each LIBOR selection, the length of the applicable Fixed Rate Term. Any such notice may be given by telephone (or such other electronic method as Bank may permit) so long as, with respect to each LIBOR selection, (i) if requested by Bank, Borrower provides to Bank written confirmation thereof not later than 3 Business Days after such notice is given, and (ii) such notice is given to Bank prior to 10:00 a.m. on the first day of the Fixed Rate Term, or at a later time during any Business Day if Bank, at it’s sole option but without obligation to do so, accepts Borrower’s notice and quotes a fixed rate to Borrower. If Borrower does not immediately accept a fixed rate when quoted by Bank, the quoted rate shall expire and any subsequent LIBOR request from Borrower shall be subject to a redetermination by Bank of the applicable fixed rate. If no specific designation of interest is made at the time any advance is requested hereunder or at the end of any Fixed Rate Term, Borrower shall be deemed to have made a Prime Rate interest selection for such advance or the principal amount to which such Fixed Rate Term applied.

2.3                      Taxes and Regulatory Costs. Borrower shall pay to Bank immediately upon demand, in addition to any other amounts due or to become due hereunder, any and all (a) withholdings, interest equalization taxes, stamp taxes or other taxes (except income and franchise taxes) imposed by any domestic or foreign governmental authority and related in any manner to LIBOR, and (b) future, supplemental, emergency or other changes in the LIBOR Reserve Percentage, assessment rates imposed by the Federal Deposit Insurance Corporation, or similar requirements or costs imposed by any domestic or foreign governmental authority or resulting from compliance by Bank with any request or directive (whether or not having the force of law) from any central bank or other governmental authority and related in any manner to LIBOR to the extent they are not included in the calculation of LIBOR. In determining which of the foregoing are attributable to any LIBOR option available to Borrower hereunder, any reasonable allocation made by Bank among its operations shall be conclusive and binding upon Borrower.

2.4                      Payment of Interest. Interest accrued on this Note shall be payable on the 1st day of each month, commencing January 1, 2008.

2.5                      Default Interest. From and after the maturity date of this Note, or such earlier date as all principal owing hereunder becomes due and payable by acceleration or otherwise, the outstanding principal balance of this Note shall bear interest until paid in full at an increased rate per annum (computed on the basis of a 360-day year, actual days elapsed) equal to 4% above the rate of interest from time to time applicable to this Note.

2

3.                         BORROWING AND REPAYMENT:

3.1                      Borrowing and Repayment. Borrower may from time to time during the term of this Note borrow, partially or wholly repay its outstanding borrowings, and reborrow, subject to all of the limitations, terms and conditions of this Note and of the Credit Agreement between Borrower and Bank defined below; provided however, that the total outstanding borrowings under this Note shall not at any time exceed the principal amount stated above. The unpaid principal balance of this obligation at any time shall be the total amounts advanced hereunder by the holder hereof less the amount of principal payments made hereon by or for Borrower, which balance may be endorsed hereon from time to time by the holder. The outstanding principal balance of this Note shall be due and payable in full on January 1, 2010.

3.2                      Advances. Advances hereunder, to the total amount of the principal sum available hereunder, may be made by the holder at the oral or written request of (a) Thomas D. Brisbin, Mallory McCamant, Kimberly D. Gant, Roy Gill and Kate Nguyen, any one acting alone, who are authorized to request advances and direct the disposition of any advances until written notice of the revocation of such authority is received by the holder at the office designated above, or (b) any person, with respect to advances deposited to the credit of any deposit account of Borrower, which advances, when so deposited, shall be conclusively presumed to have been made to or for the benefit of Borrower regardless of the fact that persons other than those authorized to request advances may have authority to draw against such account. The holder shall have no obligation to determine whether any person requesting an advance is or has been authorized by Borrower.

3.3                      Application of Payments. Each payment made on this Note shall be credited first, to any interest then due and second, to the outstanding principal balance hereof. All payments credited to principal shall be applied first, to the outstanding principal balance of this Note which bears interest determined in relation to the Prime Rate, if any, and second, to the outstanding principal balance of this Note which bears interest determined in relation to LIBOR, with such payments applied to the oldest Fixed Rate Term first.

4.                         PREPAYMENT:

4.1                      Prime Rate. Borrower may prepay principal on any portion of this Note which bears interest determined in relation to the Prime Rate at any time, in any amount and without penalty.

4.2                      LIBOR. Borrower may prepay principal on any portion of this Note which bears interest determined in relation to LIBOR at any time and in the minimum amount of $100,000.00; provided however, that if the outstanding principal balance of such portion of this Note is less than said amount, the minimum prepayment amount shall be the entire outstanding principal balance thereof. In consideration of Bank providing this prepayment option to Borrower, or if any such portion of this Note shall become due and payable at any time prior to the last day of the Fixed Rate Term applicable thereto by acceleration or otherwise, Borrower shall pay to Bank immediately upon demand a fee which is the sum of the discounted monthly differences for each month from the month of prepayment through the month in which such Fixed Rate Term matures, calculated as follows for each such month:

(a)                       Determine the amount of interest which would have accrued each month on the amount prepaid at the interest rate applicable to such amount had it remained outstanding until the last day of the Fixed Rate Term applicable thereto.

(b)                      Subtract from the amount determined in (a) above the amount of interest which would have accrued for the same month on the amount prepaid for the remaining term of such Fixed Rate Term at LIBOR in effect on the date of prepayment for new loans made for such term and in a principal amount equal to the amount prepaid.

(c)                       If the result obtained in (b) for any month is greater than zero, discount that difference by LIBOR used in (b) above.

3

Borrower acknowledges that prepayment of such amount may result in Bank incurring additional costs, expenses and/or liabilities, and that it is difficult to ascertain the full extent of such costs, expenses and/or liabilities. Borrower, therefore, agrees to pay the above-described prepayment fee and agrees that said amount represents a reasonable estimate of the prepayment costs, expenses and/or liabilities of Bank. If Borrower fails to pay any prepayment fee when due, the amount of such prepayment fee shall thereafter bear interest until paid at a rate per annum 2.000% above the Prime Rate in effect from time to time (computed on the basis of a 360-day year, actual days elapsed).

5.                         EVENTS OF DEFAULT:

This Note is made pursuant to and is subject to the terms and conditions of that certain Credit Agreement between Borrower and Bank dated as of December 28, 2007, as amended from time to time (the “Credit Agreement”).

Any such payments made by Bank shall be obligations of Debtor to Bank, due and payable immediately upon demand, together with interest at a rate determined in accordance with the provisions of this Agreement, and shall be secured by the Collateral and Proceeds, subject to all terms and conditions of this Agreement.

9.                               EVENTS OF DEFAULT. The occurrence of any of the following shall constitute an “Event of Default” under this Agreement: (a) any default in the payment or performance of any obligation, or any defined event of default, under (i) any contract or instrument evidencing any Indebtedness, or (ii) any other agreement between Debtor and Bank, including without limitation any loan agreement, relating to or executed in connection with any Indebtedness; (b) any representation or warranty made by Debtor herein shall prove to be incorrect, false or misleading in any material respect when made; (c) Debtor shall fail to observe or perform any obligation or agreement contained herein; (d) any impairment of the rights of Bank in any Collateral or Proceeds or any attachment or like levy on any property of Debtor; and (e) Bank, in good faith, believes any or all of the Collateral and/or Proceeds to be in danger of misuse, dissipation, commingling, loss, theft, damage or destruction, or otherwise in jeopardy or unsatisfactory in character or value.

10.                         REMEDIES. Upon the occurrence of any Event of Default, Bank shall have the right to declare immediately due and payable all or any Indebtedness secured hereby and to terminate any commitments to make loans or otherwise extend credit to Debtor. Bank shall have all other rights, powers, privileges and remedies granted to a secured party upon default under the California Uniform Commerical Code or otherwise provided by law, including without limitation, the right (a) to contact all persons obligated to Debtor on any Collateral or Proceeds and to instruct such persons to deliver all Collateral and/or Proceeds directly to Bank, and (b) to sell, lease, license or otherwise dispose of any or all Collateral. All rights, powers, privileges and remedies of Bank shall be cumulative. No delay, failure or discontinuance of Bank in exercising any right, power, privilege or remedy hereunder shall affect or operate as a waiver of such right, power, privilege or remedy; nor shall any single or partial exercise of any such right, power, privilege or remedy preclude, waive or otherwise affect any other or further exercise thereof or the exercise of any other right, power, privilege or remedy. Any waiver, permit, consent or approval of any kind by Bank of any default hereunder, or any such waiver of any provisions or conditions hereof, must be in writing and shall be effective only to the extent set forth in writing. It is agreed that public or private sales or other dispositions, for cash or on credit, to a wholesaler or retailer or investor, or user of property of the types subject to this Agreement, or public auctions, are all commercially reasonable since differences in the prices generally realized in the different kinds of dispositions are ordinarily offset by the differences in the costs and credit risks of such dispositions.

While an Event of Default exists: (a) Debtor will deliver to Bank from time to time, as requested by Bank, current lists of all Collateral and Proceeds; (b) Debtor will not dispose of any Collateral or Proceeds except on terms approved by Bank; (c) at Bank’s request, Debtor will assemble and deliver all Collateral and Proceeds, and books and records pertaining thereto, to Bank at a reasonably convenient place designated by Bank; and (d) Bank may, without notice to Debtor, enter onto Debtor’s premises and take possession of the Collateral. Debtor further agrees that Bank shall have no obligation to process or prepare any Collateral for sale or other disposition.

11.                         DISPOSITION OF COLLATERAL AND PROCEEDS; TRANSFER OF INDEBTEDNESS. In disposing of Collateral hereunder, Bank may disclaim all warranties of title, possession, quiet enjoyment and the like. Any proceeds of any disposition of any Collateral or Proceeds, or any part thereof, may be applied by Bank to the

3

payment of expenses incurred by Bank in connection with the foregoing, including reasonable attorneys’ fees, and the balance of such proceeds may be applied by Bank toward the payment of the Indebtedness in such order of application as Bank may from time to time elect. Upon the transfer of all or any part of the Indebtedness, Bank may transfer all or any part of the Collateral or Proceeds and shall be fully discharged thereafter from all liability and responsibility with respect to any of the foregoing so transferred, and the transferee shall be vested with all rights and powers of Bank hereunder with respect to any of the foregoing so transferred; but with respect to any Collateral or Proceeds not so transferred Bank shall retain all rights, powers, privileges and remedies herein given.

12.                         STATUTE OF LIMITATIONS. Until all Indebtedness shall have been paid in full and all commitments by Bank to extend credit to Debtor have been terminated, the power of sale or other disposition and all other rights, powers, privileges and remedies granted to Bank hereunder shall continue to exist and may be exercised by Bank at any time and from time to time irrespective of the fact that the Indebtedness or any part thereof may have become barred by any statute of limitations, or that the personal liability of Debtor may have ceased, unless such liability shall have ceased due to the payment in full of all Indebtedness secured hereunder.

13.                         MISCELLANEOUS. When there is more than one Debtor named herein: (a) the word “Debtor” shall mean all or any one or more of them as the context requires; (b) the obligations of each Debtor hereunder are joint and several; and (c) until all Indebtedness shall have been paid in full, no Debtor shall have any right of subrogation or contribution, and each Debtor hereby waives any benefit of or right to participate in any of the Collateral or Proceeds or any other security now or hereafter held by Bank. Debtor hereby waives any right to require Bank to (i) proceed against Debtor or any other person, (ii) marshal assets or proceed against or exhaust any security from Debtor or any other person, (iii) perform any obligation of Debtor with respect to any Collateral or Proceeds, and (d) make any presentment or demand, or give any notice of nonpayment or nonperformance, protest, notice of protest or notice of dishonor hereunder or in connection with any Collateral or Proceeds. Debtor further waives any right to direct the application of payments or security for any Indebtedness of Debtor or indebtedness of customers of Debtor.

14.                         NOTICES. All notices, requests and demands required under this Agreement must be in writing, addressed to Bank at the address specified in any other loan documents entered into between Debtor and Bank and to Debtor at the address of its chief executive office (or principal residence, if applicable) specified below or to such other address as any party may designate by written notice to each other party, and shall be deemed to have been given or made as follows: (a) if personally delivered, upon delivery; (b) if sent by mail, upon the earlier of the date of receipt or 3 days after deposit in the U.

All of the foregoing shall be paid by Owner with interest from the date of demand until paid in full at a rate per annum equal to the greater of ten percent (10%) or Bank’s Prime Rate in effect from time to time.

16.                         SUCCESSORS; ASSIGNS; AMENDMENT. This Agreement shall be binding upon and inure to the benefit of the heirs, executors, administrators, legal representatives, successors and assigns of the parties, and may be amended or modified only in writing signed by Bank and Debtor.

17.                         OBLIGATIONS OF MARRIED PERSONS.

Debtor appoints Bank its true attorney-in-fact to perform any of the following powers, which are coupled with an interest, are irrevocable until termination of this Agreement and may be exercised from time to time by Bank’s officers and employees, or any of them, whether or not Debtor is in default: (a) to perform any obligation of Debtor hereunder in Debtor’s name or otherwise; (b) to give notice to account debtors or others of Bank’s rights in the Collateral and Proceeds, to enforce or forebear from enforcing the same and make extension or modification agreements with respect thereto: (c) to release persons liable on Proceeds and to give receipts and acquittances and compromise disputes in connection therewith; (d) to release or substitute security; (e) to resort to security in any order; (f) to prepare, execute, file, record or deliver notes, assignments, schedules, designation statements, financing statements, continuation statements, termination statements, statements of assignment, applications for registration or like papers to perfect, preserve or release Bank’s interest in the Collateral and Proceeds; (g) to receive, open and read mail addressed to Debtor; (h) to take cash, instruments for the payment of money and other property to which Bank is entitled; (i) to verify facts concerning the Collateral and Proceeds by inquiry of obligors thereon, or otherwise, in its own name or a fictitious name; (j) to endorse, collect, deliver and receive payment under instruments for the payment of money constituting or relating to Proceeds; (k) to prepare, adjust, execute, deliver and receive payment under insurance claims, and to collect and receive payment of and endorse any instrument in payment of loss or returned premiums or any other insurance refund or return, and to apply such amounts received by Bank, at Bank’s sole option, toward repayment of the Indebtedness or replacement of the Collateral; (l) to exercise all rights, powers and remedies which Debtor would have, but for this Agreement, with respect to all Collateral and Proceeds subject hereto; (m) to enter onto Debtor’s premises in inspecting the Collateral; (n) to make withdrawals from and to close deposit accounts or other accounts with any financial institution, wherever located, into which Proceeds may have been deposited, and to apply funds so withdrawn to payment of the Indebtedness; (o) to preserve or release the interest evidenced by chattel paper to which Bank is entitled hereunder and to endorse and deliver any evidence of title incidental thereto; and (p) to do all acts and things and execute all documents in the name of Debtor or otherwise, deemed by Bank as necessary, proper and convenient in connection with the preservation, perfection or enforcement of its rights hereunder.

8.                          PAYMENT OF PREMIUMS, TAXES, CHARGES, LIENS AND ASSESSMENTS. Debtor agrees to pay, prior to delinquency, all insurance premiums, taxes, charges, liens and assessments against the Collateral and Proceeds, and upon the failure of Debtor to do so, Bank at its option may pay any of them and shall be the sole judge of the legality or validity thereof and the amount necessary to discharge the same. Any such payments made by Bank shall be obligations of Debtor to Bank, due and payable immediately upon demand, together with interest at a rate determined in accordance with the provisions of this Agreement, and shall be secured by the Collateral and Proceeds, subject to all terms and conditions of this Agreement.

9.                          EVENTS OF DEFAULT. The occurrence of any of the following shall constitute an “Event of Default” under this Agreement; (a) any default in the payment or performance of any obligation, or any defined event of default, under (i) any contract or instrument evidencing any Indebtedness, or (ii) any other agreement between Debtor and Bank, including without limitation any loan agreement, relating to or executed in connection with any Indebtedness; (b) any representation or warranty made by Debtor herein shall prove to be incorrect, false or misleading in any material respect when made; (c) Debtor shall fail to observe or perform any obligation or agreement contained herein; (d) any impairment of the rights of Bank in any Collateral or Proceeds or any attachment or like levy on any property of Debtor; and (e) Bank, in good faith, believes any or all of the Collateral and/or Proceeds to be in danger of misuse, dissipation, commingling, loss, theft, damage or destruction, or otherwise in jeopardy or unsatisfactory in character or value.

10.                    REMEDIES. Upon the occurrence of any Event of Default, Bank shall have the right to declare immediately due and payable all or any Indebtedness secured hereby and to terminate any commitments to make loans or otherwise extend credit to Debtor. Bank shall have all other rights, powers, privileges and remedies granted to a secured party upon default under the California Uniform Commerical Code or otherwise provided by law, including without limitation, the right (a) to contact all persons obligated to Debtor on any

3

Collateral or Proceeds and to instruct such persons to deliver all Collateral and/or Proceeds directly to Bank, and (b) to sell, lease, license or otherwise dispose of any or all Collateral. All rights, powers, privileges and remedies of Bank shall be cumulative. No delay, failure or discontinuance of Bank in exercising any right, power, privilege or remedy hereunder shall affect or operate as a waiver of such right, power, privilege or remedy; nor shall any single or partial exercise of any such right, power, privilege or remedy preclude, waive or otherwise affect any other or further exercise thereof or the exercise of any other right, power, privilege or remedy. Any waiver, permit, consent or approval of any kind by Bank of any default hereunder, or any such waiver of any provisions or conditions hereof, must be in writing and shall be effective only to the extent set forth in writing. It is agreed that public or private sales or other dispositions, for cash or on credit, to a wholesaler or retailer or investor, or user of property of the types subject to this Agreement, or public auctions, are all commercially reasonable since differences in the prices generally realized in the different kinds of dispositions are ordinarily offset by the differences in the costs and credit risks of such dispositions.

While an Event of Default exists: (a) Debtor will deliver to Bank from time to time, as requested by Bank, current lists of all Collateral and Proceeds; (b) Debtor will not dispose of any Collateral or Proceeds except on terms approved by Bank; (c) at Bank’s request, Debtor will assemble and deliver all Collateral and Proceeds, and books and records pertaining thereto, to Bank at a reasonably convenient place designated by Bank; and (d) Bank may, without notice to Debtor, enter onto Debtor’s premises and take possession of the Collateral. With respect to any sale by Bank of any Collateral subject to this Agreement, Debtor hereby expressly grants to Bank the right to sell such Collateral using any or all of Debtor’s trademarks, trade names, trade name rights and/or proprietary labels or marks. Debtor further agrees that Bank shall have no obligation to process or prepare any Collateral for sale or other disposition.

11.                    DISPOSITION OF COLLATERAL AND PROCEEDS; TRANSFER OF INDEBTEDNESS. In disposing of Collateral hereunder, Bank may disclaim all warranties of title, possession, quiet enjoyment and the like. Any proceeds of any disposition of any Collateral or Proceeds, or any part thereof, may be applied by Bank to the payment of expenses incurred by Bank in connection with the foregoing, including reasonable attorneys’ fees, and the balance of such proceeds may be applied by Bank toward the payment of the Indebtedness in such order of application as Bank may from time to time elect. Upon the transfer of all or any part of the Indebtedness, Bank may transfer all or any part of the Collateral or Proceeds and shall be fully discharged thereafter from all liability and responsibility with respect to any of the foregoing so transferred, and the transferee shall be vested with all rights and powers of Bank hereunder with respect to any of the foregoing so transferred; but with respect to any Collateral or Proceeds not so transferred Bank shall retain all rights, powers, privileges and remedies herein given.

12.                    STATUTE OF LIMITATIONS. Until all Indebtedness shall have been paid in full and all commitments by Bank to extend credit to Debtor have been terminated, the power of sale or other disposition and all other rights, powers, privileges and remedies granted to Bank hereunder shall continue to exist and may be exercised by Bank at any time and from time to time irrespective of the fact that the Indebtedness or any part thereof may have become barred by any statute of limitations, or that the personal liability of Debtor may have ceased, unless such liability shall have ceased due to the payment in full of all Indebtedness secured hereunder.

13.                    MISCELLANEOUS. When there is more than one Debtor named herein: (a) the word “Debtor” shall mean all or any one or more of them as the context requires; (b) the obligations of each Debtor hereunder are joint and several; and (c) until all Indebtedness shall have been paid in full, no Debtor shall have any right of subrogation or contribution, and each Debtor hereby waives any benefit of or right to participate in any of the Collateral or Proceeds or any other security now or hereafter held by Bank. Debtor hereby waives any right to require Bank to (i) proceed against Debtor or any other person, (ii) marshal assets or proceed against or exhaust any security from Debtor or any other person, (iii) perform any obligation of Debtor with respect to any Collateral or Proceeds, and (d) make any presentment or demand, or give any notice of nonpayment or nonperformance, protest, notice of protest or notice of dishonor hereunder or in connection with any Collateral or Proceeds. Debtor further waives any right to direct the application of payments or security for any Indebtedness of Debtor or indebtedness of customers of Debtor.

All of the foregoing shall be paid by Owner with interest from the date of demand until paid in full at a rate per annum equal to the greater of ten percent (10%) or Bank’s Prime Rate in effect from time to time.

16.                    SUCCESSORS; ASSIGNS; AMENDMENT. This Agreement shall be binding upon and inure to the benefit of the heirs, executors, administrators, legal representatives, successors and assigns of the parties, and may be amended or modified only in writing signed by Bank and Debtor.

17.                    OBLIGATIONS OF MARRIED PERSONS. Any married person who signs this Agreement as Debtor hereby expressly agrees that recourse may be had against his or her separate property for all his or her Indebtedness to Bank secured by the Collateral and Proceeds under this Agreement.

18.                    SEVERABILITY OF PROVISIONS. If any provision of this Agreement shall be held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or any remaining provisions of this Agreement.
