(d)Revolving Note.  The Revolving Loans made by the Bank pursuant hereto shall be evidenced by a promissory note of the Borrower, substantially in the form of Exhibit A, with any appropriate insertions (as amended from time to time, the “Revolving Note”), payable to the order of the Bank and representing the obligation of the Borrower to pay the aggregate unpaid principal amount of all Revolving Loans made by the Bank, with interest thereon as prescribed in Section 2.04. The Bank is hereby authorized to record in its books and records and on any schedule annexed to the Revolving Note, the date and amount of each Revolving Loan made by the Bank, the date and amount of each payment of principal thereof, and the applicable interest rate, and any such recordation shall constitute prima facie evidence of the accuracy of the information so recorded; provided that failure by the Bank to effect such recordation shall not affect the Borrower’s obligations hereunder.  Prior to the transfer of the Revolving Note, the Bank shall record such information on any schedule annexed to and forming a part of the Revolving Note.

With respect to each LIBOR option selected hereunder, Bank is hereby authorized to note the date, principal amount, interest rate and applicable LIBOR Rate Term 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.

1

4.“Dollars” means United States of America dollars.

5.“LIBOR Rate Portion” means a portion of the principal amount outstanding under this Note which is bearing interest at a rate related to LIBOR. No LIBOR Rate Portion shall be less than Two Hundred Fifty Thousand Dollars ($250,000).

6.“LIBOR Rate Term” means a period commencing on a Business Day and continuing for one (1) month, two (2) months, three (3) months, six (6) months or twelve (12) 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 Bank’s LIBOR; provided however, that no LIBOR Rate Term shall extend beyond the scheduled maturity date hereof. The last day of the interest period will be determined by Bank using the Designated LIBOR Market. If any LIBOR Rate Term would end on a day which is not a Business Day, then such LIBOR Rate Term shall be extended to the next succeeding Business Day.

7.“LIBOR Rate” means the interest rate determined by the following formula, rounded upward, if necessary, to the nearest 1/100 of one percent. (All amounts in the calculation will be determined by Bank as of the first day of the interest period.)

LIBOR Rate =	LIBOR Base Rate
	(1.00 - Reserve Percentage)

(a)“LIBOR Base Rate” means, with respect to any Revolving Loan to be made by Bank which is to bear interest in relation to the LIBOR Rate, the interest rate per annum (rounded upward, if necessary, to the nearest 1/100^th of 1%) at which deposits in Dollars are offered by Bank through its Los Angeles office to prime banks in the Designated LIBOR Market on the first day of the applicable LIBOR Rate Term in an aggregate amount approximately equal to the amount of the Revolving Loan to be made by Bank and for a period of time comparable to the number of days in the applicable LIBOR Rate Term.  The determination of the LIBOR Base Rate by Bank shall be conclusive in the absence of manifest error.

(b)“Reserve Percentage” means, with respect to any Revolving Loan to be made by Bank which is to bear interest in relation to the LIBOR Rate, the maximum reserve percentage (expressed as a decimal, rounded upward, if necessary, to the nearest 1/100 of one percent) in effect on the date the LIBOR Base Rate for the Revolving Loan is determined (whether or not such reserve percentage is applicable to Bank) under regulations issued from time to time by the Federal Reserve Board for determining the maximum reserve requirement (including any emergency, supplemental or other marginal reserve requirement) with respect to eurocurrency funding (currently referred to as “eurocurrency liabilities”) having a term comparable to the LIBOR Rate Term for such Revolving Loan.  The determination by Bank of any applicable Reserve Percentage shall be conclusive in the absence of manifest error.

8.“Reference Rate” means the variable per annum rate of interest most recently announced by Bank at its corporate headquarters as the “Union Bank of California, N.A. Reference Rate,” with the understanding that the “Union Bank of California, N.A. Reference Rate” is one of Bank’s index rates and merely serves as a basis upon which effective rates of

2

interest are calculated for loans making reference thereto and may not be the lowest or best rate at which Bank calculates interest or extends credit.  Any change in the Reference Rate announced by Bank shall take effect at the opening of business on the day specified in the announcement of such change.

B.INTEREST:

1.Payment of Interest. Interest accrued on this Note shall be payable on the fifteenth (15^th) day of each month for the prior month or portion thereof, commencing July 15, 2004.

2.Selection of Interest Rate Options. At any time any portion of this Note bears interest determined in relation to the LIBOR Rate, it may be continued by Borrower at the end of the LIBOR Rate Term applicable thereto so that all or a portion thereof bears interest determined in relation to the Reference Rate or in relation to the LIBOR Rate for a new LIBOR Rate Term designated by Borrower. At any time any portion of this Note bears interest determined in relation to the Reference Rate, Borrower may convert all or a portion thereof so that it bears interest determined in relation to the LIBOR Rate for a LIBOR Rate Term designated by Borrower. At the time each advance is requested hereunder or Borrower wishes to select the LIBOR option for all or a portion of the outstanding principal balance hereof, and at the end of each LIBOR Rate Term, Borrower shall give Bank notice specifying (a) the interest rate option selected by Borrower, (b) the principal amount subject thereto, and (c) if the LIBOR option is selected, the length of the applicable LIBOR Rate Term. Any such notice may be given by telephone so long as, with respect to each LIBOR selection, such notice is given to Bank prior to 10:00 a.m., California time, on the third Business Day prior to the commencement of the LIBOR Rate Term and, with respect to each Reference Rate selection, such notice is given to Bank prior to 11:00 a.m., California time, on the day of the requested advance. For each LIBOR option requested hereunder, Bank will quote the applicable LIBOR Rate to Borrower at approximately 10:00 a.m., California time, on the second Business Day prior to the LIBOR Rate Term. If Borrower does not immediately accept the rate quoted by Bank, any subsequent acceptance by Borrower shall be subject to a re-determination by Bank of the applicable LIBOR Rate; provided however, that if Borrower fails to accept any such rate by 11:00 a.m., California time, on the Business Day such quotation is given, then the quoted rate shall expire and Bank shall have no obligation to permit a LIBOR option to be selected on such day. If no specific designation of interest is made at the time any advance is requested hereunder or at the end of any LIBOR Rate Term, Borrower shall be deemed to have made a Reference Rate interest selection for such advance or the principal amount to which such LIBOR Rate Term applied.

3.Additional LIBOR Provisions.

(a)If Bank at any time shall determine that for any reason adequate and reasonable means do not exist for ascertaining the LIBOR Rate, then Bank shall promptly give notice thereof to Borrower. If such notice is given and until such notice has been withdrawn by Bank, than (i) no new LIBOR option may be selected by Borrower, and (ii) any portion of the outstanding principal balance hereof which bears interest determined in relation to the LIBOR Rate, subsequent to the end of the LIBOR Rate Term applicable thereto, shall bear interest determined in relation to the Reference Rate.

3

(b)If any law, treaty, rule, regulation or determination of a court or governmental authority or any change therein or in the interpretation or application thereof (each, a “Change in Law”) shall make it unlawful for Bank (i) to make LIBOR options available hereunder, or (ii) to maintain interest rates based on the LIBOR Rate, then in the former event, any obligation of Bank to make available such unlawful LIBOR options shall immediately be cancelled, and in the latter event, any such unlawful LIBOR-based interest rates then outstanding shall be converted, at Bank’s option, so that interest on the portion of the outstanding principal balance subject thereto is determined in relation to the Reference Rate; provided however, that if any such Change in Law shall permit any LIBOR-based interest rates to remain in effect until the expiration of the LIBOR Rate Term applicable thereto, then such permitted LIBOR-based interest rates shall continue in effect until the expiration of such LIBOR Rate Term. Upon the occurrence of any of the foregoing events, Borrower shall pay to Bank immediately upon demand such amounts as may be necessary to compensate Bank for any fines, fees, charges, penalties or other costs incurred or payable by Bank as a result thereof and which are attributable to any LIBOR options made available to Borrower hereunder, and any reasonable allocation made by Bank among its operations shall be conclusive and binding upon Borrower.

(c)If any Change in Law or compliance by Bank with any request or directive (whether or not having the force of law) from any central bank or other governmental authority shall:

(i)subject Bank to any tax, duty or other charge with respect to any LIBOR options, or change the basis of taxation of payments to Bank of principal, interest, fees or any other amount payable hereunder (except for changes in the rate of tax on the overall net income of Bank); or

(ii)impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by, deposits or other liabilities in or for the account of advances or loans by, or any other acquisition of funds by any office of Bank; or

(iii)impose on Bank any other condition; and the result of any of the foregoing is to increase the cost to Bank of making, renewing or maintaining any LIBOR options hereunder and/or to reduce any amount receivable by Bank in connection therewith, then in any such case, Borrower shall pay to Bank immediately upon demand such amounts as may be necessary to compensate Bank for any additional costs incurred by Bank and/or reductions in amounts received by Bank which are attributable to such LIBOR options. In determining which costs incurred by Bank and/or reductions in amounts received by Bank are attributable to any LIBOR options made available to Borrower hereunder, any reasonable allocation made by Bank among its operations shall be conclusive and binding upon Borrower.

(d)Bank will have no obligation to accept an election of Borrower for the LIBOR option if any of the following described events has occurred and is continuing:

4

(i)Dollar deposits in the principal amount, and for periods equal to the LIBOR Rate Term, of any Revolving Loan which bears interest in relation to the LIBOR Rate are not available in the Designated LIBOR Market; or

(ii)  an Event of Default has occurred and is continuing; or

(iii) the LIBOR Rate does not accurately reflect the cost of any Revolving Loan which bears interest in relation to the LIBOR Rate.

4.Default Interest. During the continuance of an Event of Default, 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 and actual days elapsed, which results in more interest than if a 365-day year were used) equal to two percent (2.00%) above the rate of interest from time to time applicable to this Note (the “Default Rate”).

C.BORROWING AND REPAYMENT:

1.Loan and Repayment. Borrower may from time to time during the term of this Note borrow, partially or wholly repay its outstanding borrowings, and re-borrow, subject to all of the limitations, terms and conditions of this Note and of any document executed in connection with or governing this Note, including the Credit Agreement; 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 the “Maturity Date” (as defined in the Credit Agreement).

2.Advances. Advances hereunder, to the total amount of the principal sum stated above, may be made by the holder at the oral or written request of (a) Borrower’s Chief Financial Officer, Vice President-Finance, Vice President-Treasurer, or Controller, 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 account of Borrower with the holder, 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.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. Unless instructed otherwise by Borrower, 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 Reference Rate, if any, and second, to the outstanding principal balance of this Note which bears interest determined in relation to the LIBOR Rate, with such payments applied to the oldest LIBOR Rate Term first.

5

4.Prepayment.

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

(b)LIBOR. Each prepayment of a LIBOR Rate Portion shall be not less than $250,000 and shall be in an integral multiple of $100,000, and Bank shall have received notice of each such prepayment on the date that is five (5) Business Days before the date of such prepayment (which notice shall identify the date and amount of the prepayment).  Each prepayment of a LIBOR Rate Portion, whether voluntary, by reason of acceleration or otherwise, will be accompanied by the amount of accrued interest on the amount prepaid, and a prepayment fee as described below. A “prepayment” is a payment on a date earlier than the last day of the applicable LIBOR Rate Term. The prepayment fee shall be equal to the amount (if any) by which:

(i)the additional interest which would have been payable during the applicable LIBOR Rate Term on the amount prepaid had it not been prepaid, exceeds

(ii)the interest which would have been recoverable by Bank by placing the amount prepaid on deposit in the domestic certificate of deposit market, the eurodollar deposit market, or other appropriate money market selected by Bank for a period starting on the date on which it was prepaid and ending on the last day of the applicable LIBOR Rate Term.

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 two percent (2.00%)above the Reference Rate in effect from time to time (computed on the basis of a 360-day year, actual days elapsed).

D.EVENTS OF DEFAULT:

This Note is made pursuant to and is subject to the terms and conditions of the Credit Agreement.  Any default in the payment or performance of any obligation under this Note, or any defined event of default under the Credit Agreement, shall constitute an “Event of Default” under this Note.

E.MISCELLANEOUS:

1.Remedies.  Upon the occurrence and during the continuation of any Event of Default, the holder of this Note, at the holder’s option, without notice upon the occurrence and during the continuation of an Event of Default pursuant to Section 7.01(g) of the Credit Agreement, and with notice upon the occurrence of any other Event of Default, may declare all

6

sums of principal and interest outstanding hereunder to be immediately due and payable without presentment, demand, protest or notice of dishonor, all of which are expressly waived by Borrower, and the obligation, if any, of the holder to extend any further credit hereunder shall immediately cease and terminate. Borrower shall pay to the holder immediately upon demand the full amount of all payments, advances, charges, costs and expenses, including reasonable attorneys’ fees (to include outside counsel fees and all allocated costs of the holder’s in-house counsel), incurred by the holder in connection with the enforcement of the holder’s rights and/or the collection of any amounts which become due to the holder under this Note, and the prosecution or defense of any action in any way related to this Note, including without limitation, any action for declaratory relief, and including any of the foregoing incurred in connection with any bankruptcy proceeding relating to Borrower.

2.Obligations Joint and Several. Should more than one person or entity sign this Note as a Borrower, the obligations of each such Borrower shall be joint and several.

3.Replacement of Prior Revolving Note.  This Note amends, restates, replaces and supercedes (but does not create a novation of the indebtedness evidenced by) the Revolving Note, dated June 6, 2003, in the principal amount of $15,000,000, executed by Borrower to the order of Bank in connection with the Old Credit Agreement.

4.Governing Law. This Note shall be governed by and construed in accordance with the laws of the State of California, except to the extent Bank has greater rights or remedies under Federal law, whether as a national bank or otherwise, in which case such choice of California law shall not be deemed to deprive Bank of any such rights and remedies as may be available under Federal law.

B.INTEREST:

1.Payment of Interest. Interest accrued on this Note shall be payable on the fifteenth (15^th) day of each month for the prior month or portion thereof, commencing on the first such date to occur after the funding of the Term Loan evidenced by this Note.

2.Selection of Interest Rate Options. At any time any portion of this Note bears interest determined in relation to the LIBOR Rate, it may be continued by Borrower at the end of the LIBOR Rate Term applicable thereto so that all or a portion thereof bears interest determined in relation to the Reference Rate or in relation to the LIBOR Rate for a new LIBOR Rate Term designated by Borrower. At any time any portion of this Note bears interest determined in relation to the Reference Rate, Borrower may convert all or a portion thereof so that it bears interest determined in relation to the LIBOR Rate for a LIBOR Rate Term designated by Borrower.

In determining which costs incurred by Bank and/or reductions in amounts received by Bank are attributable to any LIBOR options made available to Borrower hereunder, any reasonable allocation made by Bank among its operations shall be conclusive and binding upon Borrower.

(d)Bank will have no obligation to accept an election of Borrower for the LIBOR option if any of the following described events has occurred and is continuing:

4

(i)Dollar deposits in the principal amount, and for periods equal to the LIBOR Rate Term, of any portion of the Term Loan which bears interest in relation to the LIBOR Rate are not available in the Designated LIBOR Market; or

(ii)an Event of Default has occurred and is continuing; or

(iii)the LIBOR Rate does not accurately reflect the cost of any portion of the Term Loan which bears interest in relation to the LIBOR Rate.

4.Default Interest. During the continuance of an Event of Default, 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 and actual days elapsed, which results in more interest than if a 365-day year were used) equal to two percent (2.00%) above the rate of interest from time to time applicable to this Note (the “Default Rate”).

C.BORROWING AND REPAYMENT:

1.Loan and Repayment. On or before September 30, 2005, Borrower will make a payment that will reduce the outstanding principal balance of this Note to no more than $10,000,000; provided that if the outstanding balance of this Note on September 30, 2005 is equal to or less than $10,000,000, then no payment will be required.  The outstanding principal balance of this Note shall be due and payable in full on the earlier of (a) September 30, 2006 and (b) upon the termination of the Revolving Commitment, for any reason.

2.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. Unless instructed otherwise by Borrower, 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 Reference Rate, if any, and second, to the outstanding principal balance of this Note which bears interest determined in relation to the LIBOR Rate, with such payments applied to the oldest LIBOR Rate Term first.

3.Prepayment.

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

(b)LIBOR. Each prepayment of a LIBOR Rate Portion shall be not less than $250,000 and shall be in an integral multiple of $100,000, and Bank shall have received notice of each such prepayment on the date that is five (5) Business Days before the date of such prepayment (which notice shall identify the date and amount of the prepayment).  Each prepayment of a LIBOR Rate Portion, whether voluntary, by reason of acceleration or otherwise, will be accompanied by the amount of accrued interest on the amount prepaid, and a prepayment fee as described below. A “prepayment” is a payment on a date earlier than the last day of the

5

applicable LIBOR Rate Term. The prepayment fee shall be equal to the amount (if any) by which:

(i)the additional interest which would have been payable during the applicable LIBOR Rate Term on the amount prepaid had it not been prepaid, exceeds

(ii)the interest which would have been recoverable by Bank by placing the amount prepaid on deposit in the domestic certificate of deposit market, the eurodollar deposit market, or other appropriate money market selected by Bank for a period starting on the date on which it was prepaid and ending on the last day of the applicable LIBOR Rate Term.

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 two percent (2.00%)above the Reference Rate in effect from time to time (computed on the basis of a 360-day year, actual days elapsed).

D.EVENTS OF DEFAULT:

This Note is made pursuant to and is subject to the terms and conditions of the Credit Agreement.  Any default in the payment or performance of any obligation under this Note, or any defined event of default under the Credit Agreement, shall constitute an “Event of Default” under this Note.

E.MISCELLANEOUS:

1.Remedies.  Upon the occurrence and during the continuation of any Event of Default, the holder of this Note, at the holder’s option, without notice upon the occurrence and during the continuation of an Event of Default pursuant to Section 7.01(g) of the Credit Agreement, and with notice upon the occurrence of any other Event of Default, may declare all sums of principal and interest outstanding hereunder to be immediately due and payable without presentment, demand, protest or notice of dishonor, all of which are expressly waived by Borrower, and the obligation, if any, of the holder to extend any further credit hereunder shall immediately cease and terminate. Borrower shall pay to the holder immediately upon demand the full amount of all payments, advances, charges, costs and expenses, including reasonable attorneys’ fees (to include outside counsel fees and all allocated costs of the holder’s in-house counsel), incurred by the holder in connection with the enforcement of the holder’s rights and/or the collection of any amounts which become due to the holder under this Note, and the prosecution or defense of any action in any way related to this Note, including without limitation, any action for declaratory relief, and including any of the foregoing incurred in connection with any bankruptcy proceeding relating to Borrower.

2.Obligations Joint and Several. Should more than one person or entity sign this Note as a Borrower, the obligations of each such Borrower shall be joint and several.

3.Governing Law. This Note shall be governed by and construed in accordance with the laws of the State of California, except to the extent Bank has greater rights or remedies under Federal law, whether as a national bank or otherwise, in which case such choice of California law shall not be deemed to deprive Bank of any such rights and remedies as may be available under Federal law.
