Within the limits of the Line Limit and subject to the other terms and conditions hereof, Borrower may borrow, repay, prepay and reborrow from time to time. 2.1.2 Bank shall have no obligation to make any Advance after the expiration date of the Line unless the term of the Line is extended by Bank, in writing, at its sole option; however, any Advance actually made by Bank to Borrower after such date or in excess of the Line Limit or any extension or renewal of the Line shall be entitled to all of the benefits of this Agreement, including but not limited to the Events of Default and related remedies set forth herein. 2.1.3 Any request for an Advance or extension of credit under the Line shall be deemed a representation and warranty by Borrower that all of the conditions precedent of Section 4 are satisfied as of the date of the request. 2.2 PURPOSE. Proceeds of Advances pursuant to the Line are to be used solely for Borrower's general operating purposes. 2.3 INTEREST. 2.3.1 OPTIONS. Borrower may choose one of the following interest rate options for any Advance under the Line, as described and defined more fully in this paragraph 2.3. (a) PRIME RATE OPTION. One or more Advances may bear interest at a per annum rate equal to Bank's Prime Rate, with adjustments to the interest rate made concurrently with and on the same day as each change in the Prime Rate. Interest is calculated on the basis of a year of 360 days and the actual number of days elapsed. -2- (b) ADJUSTED LIBOR OPTION. One or more Advances may bear interest at a per annum rate equal to 150 basis points in excess of the Adjusted LIBOR Rate for the Interest Period selected by Borrower (1, 2, 3 or 6 months) for such Advance, subject to availability of the LIBOR market to Bank. Advances under this option shall be in a minimum principal amount of $250,000 and greater amounts in increments of $100,000 and cannot be prepaid. Interest is calculated on the basis of a year of 360 days and the actual number of days elapsed. 2.3.2 INTEREST RATE CALCULATION METHODS; DEFINITIONS. Interest under the various interest rate options, set forth above, will be calculated as follows: (a) The "ADJUSTED LIBOR RATE" applicable to any Interest Period means a rate per annum determined pursuant to the following formula: [LIBOR]* ------------ ALR = [1.00 - ERP] ALR = Adjusted LIBOR Rate LIBOR = London Interbank Offered Reference Rate ERP = Euro-Dollar Reserve Percentage - ------------------ * The amount in brackets being rounded upwards, if necessary, to the next higher 1/16 of 1%. (i) The "LONDON INTERBANK OFFERED REFERENCE RATE" or "LIBOR" applicable to any Interest Period means the per annum rate of interest determined by Bank to be the rate at which deposits in dollars are offered in the London Interbank market as quoted by Telerate, Inc. or some similar rate quotation service to which Bank or one of its affiliates subscribes between 6:30 and 7:30 a.m., Seattle time, two (2) Euro-Dollar Business Days before the first day of such Interest Period for a period of time comparable to such Interest Period. (ii) "EURO-DOLLAR RESERVE PERCENTAGE" means, for any day, that percentage (expressed as a decimal) which is in effect on such day, as prescribed by the Board of Governors of the Federal Reserve System (or any successor) for determining the maximum reserve requirement for a member bank of the Federal Reserve System in San Francisco in respect of "Eurocurrency liabilities" (or in respect of any other category of liabilities which includes deposits by reference to which the interest rate on Euro-Dollar Advances is determined or any category of extensions of credit or other assets which includes loans by a non-United States office of any Bank to United States residents). The Adjusted LIBOR Rate may be adjusted on and as of the effective date of any change in the Euro-Dollar Reserve Percentage. -3- (iii) In the event that the use of the procedure described above for determination of the Adjusted LIBOR Rate is precluded for any reason, including but not limited to format changes or cessation of publication by Telerate, Inc. or other permitted rate quotation service of such rate for more than one (1) Euro-Dollar Business Day, Bank will use as the Adjusted LIBOR Rate the rate determined by Bank to be the arithmetic average (rounded upward, if necessary, to the next higher 1/16 of 1%) of the rates quoted by two or more New York dealers in Euro-Dollar funds of recognized standing determined by Bank to most closely approximate the Telerate quote specified for determination of such rate as set forth above for deposits having a maturity comparable to the applicable Interest Period and in an amount approximately equal to the Advance to be made by Bank. (b) "INTEREST PERIOD" means, with respect to each Advance requested by Borrower bearing interest based on the Adjusted LIBOR Rate, the period commencing on the date of such Advance and ending one (1), two (2) or three (3) or six (6) months thereafter, as Borrower may elect at the time the Advance is requested, during which period the Advance shall bear interest at the Adjusted LIBOR Rate applicable to the period for the Advance as chosen by Borrower. The first day of any such Interest Period shall be either (i) the date funds are initially advanced, or (ii) for an Advance already outstanding the last day of the next preceding Interest Period applicable to such Advance or, if applicable, the last day at which interest accrued at the Prime Rate; and the last day shall be the earlier of the following: (A) the maturity date of the Master Promissory Note evidencing the Line, or (B) the date which is one (1), two (2), three (3) or six (6) months thereafter, as Borrower may elect in the applicable Advance request or interest rate election; provided that if such date is not a Euro-Dollar Business Day, the Interest Period shall be extended to the next succeeding Euro-Dollar Business Day unless such Euro-Dollar Business Day falls in another calendar month, in which case such Interest Period shall end on the next preceding Euro-Dollar Business Day; and provided further, that if the Interest Period begins on the last Euro-Dollar Business Day of a calendar month (or on a day for which there is no numerically corresponding day in the calendar month at the end of such Interest Period) the Interest Period shall end on the day which is the last Euro-Dollar Business Day of the applicable calendar month. 2.3.3 ADVANCE REQUESTS; RATE ELECTIONS. In addition to the terms and conditions of the Master Promissory Note, the following terms and conditions will apply to any Advances unless modified in writing by the parties hereto: (a) Advances hereunder and elections of or changes to interest rates and selections of Interest Periods may be telephonically or otherwise requested by a representative of Borrower so designated by Borrower; provided, however, that Borrower agrees to provide to Bank, at Bank's option and request, not more than five (5) Business -4- Days after any verbal notice, a written verification of such Advance request, rate election and/or Interest Period. Failure of Borrower to provide such written verification shall not invalidate Bank's authority to rely on verbal notice or instruction, but shall entitle Bank, in its sole discretion, to refuse to allow additional Advances hereunder. Bank may rely on any oral or written request, specification or direction from any person authorized by Borrower to request an Advance pursuant to this paragraph, which Bank believes to be genuine and shall be fully protected in doing so without any requirement to make further inquiry. (b) Each Advance request, whether written or verbal, shall specify the date of Advance, the amount, the rate calculation method (Prime Rate or Adjusted LIBOR Rate) and, if applicable, the applicable Interest Period. (c) Each rate calculation method election applicable to existing Advances, whether written or verbal, shall specify the date of Advance, the amount, the rate calculation method (Prime Rate or Adjusted LIBOR Rate), the specific outstanding Advance(s) to which the election applies and, if applicable, the last day of the Interest Period of the Advance(s) being replaced with the new Advance. In the event that Borrower fails to make a rate calculation method election on or before the end of an Interest Period for any Advance(s), to take effect immediately following such Interest Period, such Advance(s) shall, after the expiration of the current Interest Period, bear interest based on the Prime Rate until repaid or until a new election is received by Bank. (d) Borrower may at any time convert some or all of the portion of the principal outstanding under Line accruing interest at the Prime Rate to one or more Advance(s) bearing interest based on the Adjusted LIBOR Rate (if available) so long as such Advances otherwise meet the requirements of Advances of that type. (e) Unless otherwise agreed by Bank, Advance requests received by 4:00 p.m. Seattle time, of a Business Day and bearing interest at Prime Rate will be funded on the same Business Day, and Advance requests received by 10:00 a.m. of a Euro-Dollar Business Day and bearing interest based on the Adjusted LIBOR Rate will be funded on the second Euro-Dollar Business Day following the request. (f) Borrower agrees that each Advance bearing interest based on the Adjusted LIBOR Rate shall be in a principal amount of not less than two hundred fifty thousand dollars ($250,000) and greater amounts in increments of one hundred thousand dollars ($100,000). (g) Borrower agrees to indemnify and hold Bank harmless from any costs, expenses or losses of any kind incurred solely because Borrower requested an Advance which Advance request Borrower later cancels. (h) No delay, omission or course of dealing will be deemed a waiver or modification hereof unless agreed to in writing, and shall be effective only to the extent specifically set forth in writing. -5- 2.4 INCREASED COSTS; ILLEGALITY. 2.4.1 If after the date hereof, the adoption or effect of any applicable law, rule or regulation, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Bank with any applicable law, rule or regulation or any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (a) shall subject Bank to any tax, duty, fee or other charge with respect to its Advances bearing interest base don the ADjusted LIBOR Rate, its notes or its obligations to make such fixed rate loans, or shall change the basis of taxation of payments to Bank of the principal of or interest on its fixed rate loans or any other amounts due under this agreement or the Master Promissory Note (except for changes in the rate of tax on the overall net income of Bank imposed by the jurisdiction in which Advances Bank's principal executive office or office through which such Advances are made is located); or (b) shall impose, modify or deem applicable any reserve, special deposit or similar requirement (including, without limitation, any such requirement imposed by the Board of Governors of the Federal Reserve System, but excluding any such requirement included in an applicable Reserve Percentage) or shall impose on Bank or on the United States marker for LIBOR sources any other condition affecting such fixed rate loans, its notes or its obligation to make fixed rate loans; and the result of any of the foregoing is to increase the cost to Bank of making or maintaining any fixed rate loan hereunder, or to reduce the amount of any sum received or receivable by bank under the Master Promissory Note with respect thereto, by an amount deemed by bank to be material, then within fifteen (15) days after demand by bank to Borrower, Borrower shall pay to Bank such additional amount or amounts as will compensate Bank for such increased costs or reduction. 2.4.2 If after the date hereof, Bank shall have determined that the adoption or effect of any applicable law, rule or regulation regarding capital adequacy or reserve requirements, or any change therein, or any change in the interpretation or administration thereof by any governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by Bank with any applicable law, rule or regulation or any request or directive regarding capital adequacy or reserve requirements (whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on Bank's capital as a consequence of its obligations hereunder to a level below that which Bank could have achieved but for such effect, adoption, change or compliance (taking into consideration Bank's policies with respect to capital adequacy) by an amount deemed by Bank to be material, then from time to time, within fifteen (15) days after demand by Bank, Borrower shall pay to Bank such additional amount or amounts as will compensate Bank for such reduction. -6- 2.4.3 Bank will promptly notify Borrower of any event of which it has knowledge, occurring after the date hereof, which will entitle Bank to compensation pursuant to this paragraph 2.4 and setting forth the additional amount or amounts to be paid to it hereunder, which shall be conclusive in the absence of manifest error. In determining such amount, Bank may use any reasonable averaging and attribution methods. If Bank demands compensation under paragraph 2.4.1, Borrower may at any time, upon at least five (5) Business Days' prior notice to Bank, repay to Bank the full amount of the then-outstanding fixed rate loans together with accrued interest thereon to the date of prepayment. Concurrently with repaying such fixed rate loans, Borrower may borrow from Bank an Advance bearing interest based on the Prime Rate or other interest rate options available under this Agreement and not affected by such changes in an amount equal to the aggregate principal amount of such fixed rate loans, so long as such Advance otherwise meet the requirements of Advances of that type. 2.4.4 Notwithstanding any other provision of this Agreement, if (a) the introduction of or any change in or application, interpretation or administration of any law, rule or regulation shall make it unlawful or impossible, or any central bank or other governmental authority shall assert that it is unlawful, for Bank to perform its obligations hereunder to make advances funded through LIBOR sources or to continue to fund or maintain such advances hereunder, or (b) if Bank determines that the information required to compare the effective interest rate is not available through Tolerate, Inc. or some similar service because deposits in U.S. Dollars (in the applicable amounts) are not being offered to or by (as the case may be) a sufficient number of banks in the relevant market for such Interest Period, or (c) if U.S. Dollars are not being offered to Bank in the London market, or (d) if the Adjusted LIBOR Rate as determined by Bank will not adequately and fairly reflect the cost to Bank of maintaining or funding its fixed rate loans for such Interest Period, then Bank may, be notice to Borrower, suspend the right of Borrower to elect such rate and, effective at the end of the then current Interest Period (or sooner, if necessary in the reasonable opinion of Bank to comply with such law or regulation), convert all such Advances so that each bears interest based on the Prime Rate. After Bank gives such notice to Borrower, Borrower may, upon two Business Days' notice, prepay all of the Advances made by Bank at any time. Any notice by Bank under this paragraph may be written, telex, telegraphic, telephonic or facsimile means; any telephone notice shall be confirmed immediately in writing, but failure to provide such written verification shall not invalidate such telephonic notice. 2.5 REPAYMENT OF ADVANCES. 2.5.1 Borrower shall pay to Bank on demand, or if no demand is made on September 30, 1996 the aggregate outstanding principal balance of all Advances under the Line, together with all unpaid accrued interest and unpaid fees and changes.

Bank may, from time to time, at its sole option and for such periods as it may determine, extend the expiration date of the Line or any outstanding balance thereon, and such sums shall be subject to this Agreement; provided that if Bank unilaterally extends the expiration date of the Line, -7- Borrower will only be liable for loans fees after the current expiration date of the Line which have been agreed to by the parties hereto. 2.5.2 If at any time the outstanding amount of the Advances made and other credit extended by Bank to Borrower under the Line exceeds the Line Limit, Borrower shall immediately pay Bank such amount as may be necessary to reduce the outstanding Advances to an amount which is not greater than the Line Limit. 2.5.3 Prepayment of the principal amount of any Advance accruing interest based on the Adjusted LIBOR Rate before the end of the applicable Interest Period will not be allowed. 2.5.4 If any payment date hereunder or under any notes or other agreement for payment of money or any date on which performance is required hereunder or under any such agreement occurs on a day other than a Business Day, such payment shall be made or performance occur on the next succeeding Business Day; provided, that interest shall continue to accrue on any outstanding Advances until paid. 2.5.5 All payments and deposits made by Borrower to Bank shall be applied at the discretion of Bank. Borrower authorizes Bank to deduct from any of Borrower's deposit accounts with Bank such amounts as may from time to time be necessary to effect the payment required hereunder. 2.6 MASTER PROMISSORY NOTE. To evidence Borrower's indebtedness under the line, Borrower shall execute and deliver to Bank a master promissory note in substantially the form of Exhibit A attached hereto. 2.7 NOTATIONS.

BINDING ARBITRATION. Upon the demand of any party ("Party/Parties"), to a Document (as defined below), whether made before the institution of any judicial proceeding or not more than 60 days after service of a complaint, third party complaint, cross-claim or counterclaim or any answer thereto or any amendment to any of the above, any Dispute (as defined below) shall be resolved by binding arbitration in accordance with the terms of this Arbitration Program. A "Dispute" shall include any action, dispute, claim or controversy of any kind, whether founded in contract, tort, statutory or common law, equity, or otherwise, now existing or hereafter arising between any of the Parties arising out of, pertaining to or in connection with any agreement, document or instrument to which this Arbitration Program is attached or in which it appears or is referenced or any related agreements, documents, or instruments ("Documents"). Any Party who fails to submit to binding arbitration following a lawful demand by another Party shall bear all costs and expenses, including reasonable attorneys' fees, (including those incurred in any trial, bankruptcy proceeding or on appeal) incurred by the other Party in obtaining a stay of any pending judicial proceeding and compelling arbitration of any Dispute. The parties agree that any agreement, document or instrument which includes, attaches to or incorporates this Arbitration Program represents a transaction involving commerce as the at term is used in the Federal Arbitration Act, ("FAA") Title 9 United States Code. THE PARTIES UNDERSTAND THAT BY THIS AGREEMENT THEY HAVE DECIDED THAT THEIR DISPUTES SHALL BE RESOLVED BY BINDING ARBITRATION RATHER THAN IN COURT, AND ONCE DECIDED BY ARBITRATION NO DISPUTE CAN LATER BE BROUGHT, FILED OR PURSUED IN COURT. 2. GOVERNING RULES. Arbitrations conducted pursuant to this Arbitration Program shall be administered by the American Arbitration Association ("AAA"), or other mutually agreeable administrator ("Administrator") in accordance with the terms of this Arbitration Program and the Commercial Arbitration Rules of the AAA. Proceedings hereunder shall be governed by the provisions of the FAA. The arbitrator(s) shall resolve all Disputes in accordance with the applicable substantive law designated in the Documents. Judgment upon any award rendered hereunder may be entered in any court having jurisdiction; provided, however that nothing herein shall be construed to be a waiver by any party that is a bank of the protections afforded pursuant to 12 U.S.C. 91 or any similar applicable state law. 3. PRESERVATION OF REMEDIES. No provision of, nor the exercise of any rights under, this arbitration clause shall limit the right of any Party to: (1) foreclose against any real or personal property collateral or other security, or obtain a personal or deficiency award; (2) exercise self-help remedies (including repossession and setoff rights); or (3) obtain provisional or ancillary remedies such as injunctive relief, sequestration, attachment, replevin, garnishment, or the appointment of a receiver from a court having jurisdiction. Such rights can be exercised at any time except to the extent such action is contrary to a final award or decision in any arbitration proceeding. The institution and maintenance of an action as described above shall not constitute a waiver of the right of any Party to submit the Dispute to arbitration, nor render inapplicable the compulsory arbitration provisions hereof. Any claim or Dispute related to exercise of any self-help, auxiliary or other rights under this paragraph shall be a Dispute hereunder. 4. ARBITRATOR POWERS AND QUALIFICATIONS; AWARDS. The Parties agree to select a neutral "qualified" arbitrator or a panel of three "qualified" arbitrators to resolve any Dispute hereunder. "Qualified" means a practicing attorney, with not less than 10 years practice in commercial law, licensed to practice in the state of the applicable substantive law designated in the Documents. A Dispute in which the claims or amounts in controversy do not exceed $1,000,000.00, shall be decided by a single arbitrator. A single arbitrator shall have authority to render an award up to but not to exceed $1,000,000.00 including all damages of any kind whatsoever, costs, fees, attorneys' fees and expenses. Submission to a single arbitrator shall be a waiver of all Parties' claims to recover more than $1,000,000.00. A Dispute involving claims or amounts in controversy exceeding $1,000,000.00 shall be decided by a majority vote of a panel of three qualified arbitrators. The arbitrator(s) shall not have the power to award punitive or exemplary damages except where such damages are specifically provided for by statute upon which the award is based. The arbitrator(s) shall be empowered to, at the written request of any Party in any Dispute, 1) to consolidate in a single proceeding any multiple party claims that are substantially identical or based upon the same underlying transaction; 2) to consolidate any claims and Disputes between other Parties which arise out of or relate to the subject matter hereof, including all claims by or against borrowers, guarantors, sureties and or owners of collateral; and 3) to administer multiple arbitration claims as class actions in accordance with Rule 23 of the Federal Rules of Civil Procedure. In any consolidated proceeding the first arbitrator(s) selected in any proceeding shall conduct the consolidated proceeding unless disqualified due to conflict of interest. The arbitrator(s) shall be empowered to resolve any dispute regarding the terms of this arbitration clause, including questions about the arbitrability of any Dispute, but shall have no power to change or alter the terms of this Arbitration Program. The prevailing Party in any Dispute shall be entitled to recover its reasonable attorneys' fees in any arbitration, and the arbitrator(s) shall have the power to award such fees. The award of the arbitrator(s) shall be in writing and shall set forth the factual and legal basis for the award. 5. MISCELLANEOUS. All statutes of limitation applicable to any Dispute shall apply to any proceeding in accordance with this arbitration clause. The Parties agree, to the maximum extent practicable, to take any action necessary to conclude an arbitration hereunder within 180 days of the filing of a Dispute with the Administrator. The arbitrator(s) shall be empowered to impose sanctions for any Party's failure to proceed within the times established herein. Arbitrations shall be conducted in the state of the applicable substantive law designated in the Documents. The provisions of this Arbitration Program shall survive any termination, amendment, or expiration hereof or of the Documents unless the Parties otherwise expressly agree in writing. Each Party agrees to keep all Disputes and arbitration proceedings strictly confidential, except for disclosures of information required in the ordinary course of business of the Parties or as required by applicable law or regulation. If any provision of this Arbitration Program is declared invalid by any court, the remaining provisions shall not be affected thereby and shall remain fully enforceable.
