The proceeds of the initial advance under the Revolving Line of Credit shall be used to refinance all outstanding indebtedness owing under the Existing Agreement (with any such advances having the same characteristics, including, without limitation, Type and remaining Interest Period, if applicable, as the indebtedness refinanced thereby) and the proceeds of all other advances under the Revolving Line of Credit shall be used for working capital and general corporate purposes. Borrower’s obligation to repay advances under the Revolving Line of Credit shall be evidenced by a promissory note dated April 22, 2010 (the “Second Amended and Restated Revolving Line of Credit Note”), in the form attached hereto as Exhibit A, all terms of which are incorporated herein by this reference.

(b) Borrowing and Repayment. Borrower may from time to time during the Availability Period, partially or wholly repay its outstanding borrowings under the Revolving Line of Credit, and reborrow, subject to all of the limitations, terms and conditions contained herein; provided that, the total outstanding borrowings under the Revolving Line of Credit shall not at any time exceed the maximum principal amount available thereunder, as set forth above. On the Revolving Credit Maturity Date, Borrower shall repay to Bank in full the aggregate outstanding principal balance of all Revolving Credit Loans, together with all accrued and unpaid interest due thereon.

Each such notice must be received by Bank not later than 11:00 a.m. on the requested date of any Revolving Credit Borrowing, conversion or continuation. Notwithstanding anything to the contrary contained herein, any telephonic notice or other electronic communication by Borrower pursuant to this Section 2.2(a) may be given by an individual who has been authorized in writing to do so by an appropriate Responsible Officer of Borrower. Each such telephonic notice or other electronic communication must be confirmed promptly by delivery to Bank of a written Loan Notice, appropriately completed and signed by an appropriate Responsible Officer of Borrower.

If Borrower fails to specify a Type of Loan in a Loan Notice or if Borrower fails to give a timely notice requesting a conversion or continuation, then the applicable Loan(s) shall be made as, or converted to, Base Rate Loans. Any such automatic conversion to Base Rate Loans shall be effective as of the last day of the Interest Period then in effect with respect to the applicable LIBOR Loans. If Borrower requests a Revolving Credit Borrowing of, conversion to, or continuation of LIBOR Loans in any such Loan Notice, but fails to specify an Interest Period, it will be deemed to have specified an Interest Period of one month.

(d) Except as otherwise provided herein, a LIBOR Loan may be continued or converted only on the last day of an Interest Period for such LIBOR Loan. During the existence of an Event of Default: (i) no Loans may be requested as, converted to or continued as LIBOR Loans without the consent of Bank; and (ii) Bank may demand that any or all of the then outstanding Revolving Credit Loans that are LIBOR Loans be converted immediately to Base Rate Loans, whereupon Borrower shall pay any amounts due under Section 3.4 in accordance with the terms thereof due to any such conversion.

(b) (i) If any amount of principal of any Loan is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable laws.

(ii) If any amount (other than principal of any Loan) payable by Borrower under any Loan Document is not paid when due (without regard to any applicable grace periods), whether at stated maturity, by acceleration or otherwise, then such amount shall thereafter bear interest at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable laws.

(iii) While any Event of Default exists, Borrower shall pay interest on the principal amount of all outstanding Obligations hereunder at a fluctuating interest rate per annum at all times equal to the Default Rate to the fullest extent permitted by applicable laws.

(iv) Accrued and unpaid interest on past due amounts (including interest on past due interest) shall be due and payable upon demand.

(c) Interest on each Loan shall be due and payable in arrears on each Interest Payment Date applicable thereto and at such other times as may be specified herein. Interest hereunder shall be due and payable in accordance with the terms hereof before and after judgment, and before and after the commencement of any proceeding under any Bankruptcy Law.

(d) Any increase or decrease in any Applicable Rate resulting from a change in the Leverage Ratio shall become effective as of the first day of the month immediately following the month in which Borrower is required to deliver a Compliance Certificate in accordance with Section 6.3(d) for a given period (each such date, a “calculation date”); provided that the Applicable Rate in effect from the Closing Date to the first day of the month immediately following receipt by Bank of a timely delivered Compliance Certificate with respect to the fiscal quarter ending March 31, 2010 shall be determined based upon Tier 3 (as indicated in the definition of “Applicable Rate”); provided further that, if any Compliance Certificate required to be delivered in accordance with Section 6.3(d) for any given period is not delivered to Bank on or before the related calculation date, then Tier 1 (as indicated in the definition of “Applicable Rate”) shall apply, effective on the related calculation date until two Business Days after such Compliance Certificate is actually received by Bank.

- 19 -

Notwithstanding the foregoing and for the avoidance of doubt, if for any period and for any reason, the actual Leverage Ratio is higher than that reported in the Compliance Certificate, Borrower shall immediately, without the requirement of notice or demand from any Person, pay to Bank an amount equal to the excess of: (A) the amount of interest or fees that would have accrued had the Applicable Rates for the relevant period been based upon the actual Leverage Ratio for the prior period rather than the Leverage Ratio reported in the Compliance Certificate delivered for such prior period; over (B) the amount of interest or fees that was actually paid by Borrower based upon the Leverage Ratio reported in the Compliance Certificate delivered for such period.

SECTION 2.5. FEES.

(a) Unused Commitment Fee. Borrower shall pay to Bank unused commitment fees (each, an “Unused Commitment Fee”) equal to the Applicable Rate multiplied by the average daily unused amount of the Revolving Line of Credit.

All payments received by Bank after 4:00 p.m. shall be deemed received on the next succeeding Business Day and any applicable interest or fee shall continue to accrue. If any payment to be made by Borrower shall come due on a day other than a Business Day, payment shall be made on the next following Business Day, and such extension of time shall be reflected in computing interest or fees, as the case may be.

- 20 -

(b) Collection of Payments. Borrower authorizes Bank to collect all principal, interest and fees due under each credit created by the Loan Documents by charging Borrower’s deposit account number 4121261853 with Bank, or any other deposit account maintained by Borrower with Bank, for the full amount thereof. 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.

ARTICLE III

TAXES, YIELD PROTECTION

AND ILLEGALITY

SECTION 3.1. ILLEGALITY.

If Bank, in its reasonable judgment, determines that any law has made it unlawful, or that any Governmental Authority has asserted that it is unlawful, for Bank to make, maintain or fund LIBOR Loans, or to determine or charge interest rates based upon LIBOR, or any Governmental Authority has imposed material restrictions on the authority of Bank to purchase or sell, or to take deposits of, Dollars in the London interbank offered market, then, on notice thereof by Bank to Borrower, any obligation of Bank to make or continue LIBOR Loans or to convert Revolving Credit Loans that are Base Rate Loans to LIBOR Loans shall be suspended until Bank notifies Borrower that the circumstances giving rise to such determination no longer exist, which notification Bank shall give to Borrower promptly after Bank, it its reasonable judgment, makes such determination. Upon receipt of such first notice, Borrower shall, upon demand from Bank, prepay or, if applicable, convert all LIBOR Loans to Base Rate Loans, either on the last day of the Interest Period therefor, if Bank may lawfully continue to maintain such LIBOR Loans to such day, or immediately, if Bank may not lawfully continue to maintain such LIBOR Loans. Upon any such prepayment or conversion, Borrower shall also pay accrued interest on the amount so prepaid or converted and all amounts due under Section 3.4 in accordance with the terms thereof due to such prepayment or conversion.

SECTION 3.2. INABILITY TO DETERMINE RATES.

If Bank determines in connection with any request for a LIBOR Loan or a conversion to or continuation thereof that (a) Dollar deposits are not being offered to banks in the London interbank offered market for the applicable amount and Interest Period of such LIBOR Loan, (b) adequate and reasonable means do not exist for determining LIBOR for any requested Interest Period with respect to a proposed LIBOR Loan, or (c) LIBOR for any requested Interest Period with respect to a proposed LIBOR Loan does not adequately and fairly reflect the cost to Bank of funding such Loan, then Bank will promptly so notify Borrower. Thereafter, the obligation of Bank to make or maintain LIBOR Loans shall be suspended until Bank revokes such notice. Upon receipt of such notice, Borrower may revoke any pending request for a Revolving Credit Borrowing of, conversion to or continuation of LIBOR Loans or, failing that, will be deemed to have converted such request into a request for a Revolving Credit Borrowing consisting of Base Rate Loans in the amount specified therein.

- 22 -

SECTION 3.3. INCREASED COSTS.

(a) Increased Costs Generally. If any Change in Law shall:

(ii) subject Bank to any tax of any kind whatsoever with respect to this Agreement or any LIBOR Loan made by it, or change the basis of taxation of payments to Bank in respect thereof (except for taxes covered by paragraph (c) below); or

(iii) impose on Bank or the London interbank market any other condition, cost or expense affecting this Agreement or LIBOR Loans made by Bank;

and the result of any of the foregoing shall be to increase the cost to Bank of making or maintaining any LIBOR Loan (or of maintaining its obligation to make any such Loan), or to reduce the amount of any sum received or receivable by Bank hereunder (whether of principal, interest or any other amount), then, upon request of Bank, Borrower will pay to Bank such additional amount or amounts as will compensate Bank for such additional costs incurred or reduction suffered.

(b) Capital Requirements. If Bank determines that any Change in Law affecting Bank or Bank’s holding company, if any, regarding capital requirements has or would have the effect of reducing the rate of return on Bank’s capital or on the capital of Bank’s holding company, if any, as a consequence of this Agreement or the Loans made by Bank, to a level below that which Bank or Bank’s holding company could have achieved but for such Change in Law (taking into consideration Bank’s policies and the policies of Bank’s holding company with respect to capital adequacy), then from time to time Borrower will pay to Bank such additional amount or amounts as will compensate Bank or Bank’s holding company for any such reduction suffered.

(c) Taxes. Borrower shall pay to Bank immediately upon demand, in addition to any other amounts due or to become due hereunder, any and all 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. 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.

(d) Certificates for Reimbursement. A certificate of Bank setting forth the amount or amounts necessary to compensate Bank or its holding company, as the case may be, as specified in subsection (a), (b) or (c) of this Section, as well as a reasonably detailed description of the computation of such amount and the basis for determining such amount or amounts, and delivered to Borrower shall be conclusive absent manifest error. Borrower shall pay Bank the amount shown as due on any such certificate within ten days after receipt thereof.

- 23 -

(e) Delay in Requests. Failure or delay on the part of Bank to demand compensation pursuant to the foregoing provisions of this Section shall not constitute a waiver of Bank’s right to demand such compensation, provided that Borrower shall not be required to compensate Bank pursuant to the foregoing provisions of this Section for any increased costs incurred or reductions suffered more than six months prior to the date that Bank notifies Borrower of the Change in Law giving rise to such increased costs or reductions and of Bank’s intention to claim compensation therefor (except that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the six-month period referred to in this subsection shall be extended to include the period of retroactive effect thereof).

SECTION 3.4. COMPENSATION FOR LOSSES.

Upon demand of Bank from time to time, Borrower shall promptly compensate Bank for and hold Bank harmless from any loss, cost or expense incurred by it as a result of:

(c) To the fullest extent permitted by applicable law, Borrower shall not assert, and hereby waives, any claim against any Indemnitee, on any theory of liability, for special, indirect, consequential or punitive damages (as opposed to direct or actual damages) arising out of, in connection with, or as a result of, this Agreement, any other Loan Document or any document contemplated hereby, the transactions contemplated hereby or thereby, any Loan or the use of the proceeds thereof. No Indemnitee referred to in Section 9.3(b) shall be liable for any damages arising from the use by unintended recipients of any information or other materials distributed by it through telecommunications, electronic or other information transmission systems in connection with this Agreement or the other Loan Documents or the transactions contemplated hereby or thereby.

(d) The agreements in this Section 9.3 shall survive the termination of Bank’s commitment to make Loans and the repayment, satisfaction or discharge of all other Obligations.

SECTION 9.4. SUCCESSORS, ASSIGNMENT. This Agreement shall be binding upon and inure to the benefit of the heirs, executors, administrators, legal representatives, successors and assigns of the parties; provided that Borrower may not assign or transfer its interest hereunder without Bank’s prior written consent.

- 37 -

SECTION 9.5. CONFIDENTIALITY. The Confidential Information will be used by Bank solely for the purpose of evaluating Borrower’s credit request and/or Bank’s ongoing credit accommodations to Borrower. Bank will keep all the Confidential Information confidential, and will not disclose any of the Confidential Information to any person or entity, except disclosures: (a) to federal and state bank examiners, and other regulatory officials having jurisdictions over Bank; (b) to Bank’s legal counsel and auditors; (c) to other professional advisors to Bank; (d) to Bank’s representatives (which shall include, without limitation, all other banks and companies affiliated with Wells Fargo & Company) who need to know the Confidential Information for the purpose of evaluating Borrower’s credit request and/or Bank’s ongoing credit accommodations to Borrower, it being expressly understood and agreed that such representatives shall be informed of the confidential nature of the Confidential Information, and shall be required by Bank to treat the Confidential Information as confidential in accordance with the terms and conditions hereof; (e) as otherwise required by law or legal process; or (f) as otherwise authorized by Borrower in writing. In the event that Bank or any of its representatives becomes legally compelled to disclose any of the Confidential Information pursuant to clause (e) of the preceding sentence, then Bank, except as otherwise required by law, will provide notice thereof to Borrower so that Borrower, at its sole option (but without obligation to do so), may attempt to seek a protective order or other appropriate remedy and/or waive compliance with the provisions of this Agreement. The confidentiality requirement set forth herein shall not extend to any portion of the Confidential Information that: (x) is or becomes generally available to the public other than as a result of a disclosure by Bank or its representatives; (y) is or becomes available to Bank on a non-confidential basis by Borrower or any officer, employee, agent or representative of Borrower prior to its disclosure by Bank; or (z) is or becomes available to Bank on a non-confidential basis from a source other than Borrower.

SECTION 9.6. ENTIRE AGREEMENT; AMENDMENT. This Agreement and the other Loan Documents constitute the entire agreement between Borrower and Bank with respect to each credit created by the Loan Documents and supersede all prior negotiations, communications, discussions and correspondence concerning the subject matter hereof. This Agreement may be amended or modified only in writing signed by each party hereto.

SECTION 9.7. NO THIRD PARTY BENEFICIARIES. This Agreement is made and entered into for the sole protection and benefit of the parties hereto and their respective permitted successors and assigns, and no other person or entity shall be a third party beneficiary of, or have any direct or indirect cause of action or claim in connection with, this Agreement or any other of the Loan Documents to which it is not a party.

SECTION 9.8. TIME. Time is of the essence of each and every provision of this Agreement and each other of the Loan Documents.

- 38 -

SECTION 9.9. SEVERABILITY OF PROVISIONS. If any provision of this Agreement shall 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.

SECTION 9.10. COUNTERPARTS. This Agreement may be executed in any number of counterparts, each of which when executed and delivered shall be deemed to be an original, and all of which when taken together shall constitute one and the same Agreement.

SECTION 9.11. GOVERNING LAW. This Agreement shall be governed by and construed in accordance with the laws of the State of California.

SECTION 9.12. 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.

- 39 -

(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 United States 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.

- 40 -

(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.

(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.

SECTION 9.13. NO NOVATION. This Agreement amends and restates the Existing Agreement in its entirety, effective as of the Closing Date, and is not intended to constitute a novation of the obligations thereunder. Nothing contained herein shall terminate any security interests, liens, guaranties or subordinations in favor of Bank and all such security interests, guaranties and subordinations shall continue in full force and effect.

SECTION 9.14. TERMINATION OF AGREEMENT. This Agreement shall terminate (other than with respect to contingent indemnification obligations under Section 9.3) when all monetary Obligations (including, without limitation, the repayment of all Loans) have been satisfied in full and Bank has no further commitment to make credit extensions or accommodations under this Agreement.
