The Adjusted LIBOR Rate shall change with any change in the LIBOR Rate on the first day of each Interest Period and on the effective date of any change in the Reserve Adjustment. 1.2 Advances shall mean the disbursement of loan proceeds under the Note. 1.3 Available Amounts shall mean the lesser of $9,960,000.00 or 80% of the total project cost. 1.4 Bank shall mean the holder of the Note. 1.5 Borrower shall mean the maker of the Note. 1.6 Business Day shall mean any day other than a Saturday, Sunday, or other day on which commercial banks in Seattle, Washington, are authorized or required by law to close. 1.7 Commencement Date shall mean the first day of any Interest Period as requested by Borrower. 1.8 Floating Rate Loans shall mean those portions of principal of the Note accruing interest at the Floating Rate. 1.9 Floating Rate shall mean the Reference Rate plus 0% per annum. 1.10 Interest Period shall mean the period commencing on the date of any advance at or conversion to an Adjusted LIBOR Rate and ending on any date thereafter as selected by Borrower, subject to the restrictions of Section 2.3. If any Interest Period would end on a day which is not a Business Day, the Interest Period shall be extended to the next succeeding Business Day. 1.11 LIBOR Rate shall mean for any Interest Period the per annum rate, calculated on the basis of actual number of days elapsed over a year of 360 days, for U.S. Dollar deposits for a period equal to the Interest Period appearing on the display designated as "Page 3750" on the Telerate Service (or such other page on that service or such other service designated by the British Banker's Association for the display of that Association's Interest Settlement Rates for U.S. Dollar deposits) as of 11:00 a.m., London time, on the day which is two London Banking Days prior to the first day of the Interest Period. If there is no period equal to the Interest Period on the display, the LIBOR Rate shall be determined by straight-line interpolation to the nearest month (or week or day if expressed in weeks or days) corresponding to the Interest Period between the two nearest neighboring periods on the display. 1.12 LIBOR Rate Loans shall mean those portions of principal of the Note accruing interest at the Adjusted LIBOR Rate. 1.13 London Banking Day shall mean any day other than a Saturday, Sunday, or other day on which commercial banks in London, England, are authorized or required by law to close. 1.14 Note shall mean the promissory note to which this exhibit is attached. 1.15 Reference Rate shall mean the rate of interest publicly announced from time to time by Bank in San Francisco, California, as its "Reference Rate." The Reference Rate is set based on various factors, including Bank's costs and desired return, general economic conditions, and other factors, and is used as a reference point for pricing some loans. Bank may price loans to its customers at, above, or below the Reference Rate. Any change in the Reference Rate shall take effect at the opening of business on the day specified in the public announcement of a change in the Reference Rate. 1.16 Reserve Adjustment shall mean as of any day the remainder of one minus that percentage (expressed as a decimal) which is the highest of any such percentages established by the Board of Governors of the Federal Reserve System (or any successor) for required reserves (including any emergency, marginal, or supplemental reserve requirement) regardless of the aggregate amount of deposits with said member bank and without benefit of any possible credit, proration, exemptions, or offsets for time deposits established at offices of member banks located outside of the United States or for eurocurrency liabilities, if any. 1.17 Termination Date shall mean JUNE 30, 2000, or such earlier date upon which Bank makes demand for payment in full under the Note based on an Event of Default as defined in the Business Loan Agreement dated June 17, 1998. Page A-2 11 ARTICLE 2 INTEREST RATE OPTIONS 2.1 Interest Rates and Payment Date. The Note shall bear interest from the date of Advance on the unpaid principal balance outstanding from time to time at the Floating Rate or Adjusted LIBOR Rate as selected by Borrower and all accrued interest shall be payable in arrears as provided in the Note. 2.2 Procedure. Borrower may, on any London Banking Day two London Banking Days before a Commencement Date, request Bank to give an Adjusted LIBOR Rate quote for a specified loan amount and Interest Period. Bank will then quote to Borrower the available Adjusted LIBOR Rate. Borrower shall have two hours from the time of the quote to elect an Adjusted LIBOR Rate by giving Bank irrevocable notice of such election. 2.3 Restrictions. Each Interest Period shall be one month or two months or three months or any other term acceptable to Bank in its sole discretion. In no event shall an Interest Period extend beyond the Termination Date. The minimum amount of a LIBOR Rate Loan shall be $250,000. 2.4 Prepayments. If Borrower prepays all or any portion of a LIBOR Rate Loan prior to the end of an Interest Period, there shall be due at the time of any such prepayment the Prepayment Fee, determined in accordance with Form 51-6325 which is attached as Exhibit 1 to the Note. In all other cases no prepayment fee shall be payable. 2.5 Reversion to Floating. The Note shall bear interest at the Floating Rate unless an Adjusted LIBOR Rate is specifically selected. At the termination of any Interest Period each LIBOR Rate Loan shall revert to a Floating Rate Loan unless Borrower directs otherwise pursuant to Section 2.2. 2.6 Inability to Participate in Market. If Bank in good faith cannot participate in the Eurodollar market for legal or practical reasons, the Adjusted LIBOR Rate shall cease to be an interest rate option. Bank shall notify Borrower of and when it again becomes legal or practical to participate in the Eurodollar market, at which time the Adjusted LIBOR Rate shall resume being an interest rate option. 2.7 Basis of Quotes. Borrower acknowledges that Bank may or may not in any particular case actually match-fund a LIBOR Rate Loan. FDIC assessments, and Federal Reserve Board reserve requirements, if any are assessed, will be based on Bank's best estimates of its marginal cost for each of these items. Whether such estimates in fact represent the actual cost to Bank for any particular dollar or Eurodollar deposit or any LIBOR Rate Loan will depend upon how Bank actually chooses to fund the LIBOR Rate Loan. By electing an Adjusted LIBOR Rate, Borrower waives any right to object to Bank's means of calculating the Adjusted LIBOR Rate quote accepted by Borrower. ARTICLE 3 ADVANCES 3.1 Revolving Loan Facility. Bank shall until the earlier of demand or the Termination Date make Advances to Borrower from time to time, to the extent of the Available Amounts, with the aggregate principal amount at any one time outstanding not to exceed $9,960,000.00. Borrower may borrow, prepay, and reborrow the principal of the Note in whole or in part. 3.2 Procedure for Advances. Borrower may borrow on any Business Day. Borrower shall give Bank irrevocable notice (written or oral) specifying the amount to be borrowed and the requested borrowing date. Bank must receive such notice on or before 11:30 a.m., Seattle time, on the day borrowing is requested. All Advances shall be discretionary to the extent notification by Borrower is given subsequent to that time. Page A-1 12 Exhibit 1 -- PREPAYMENT FEES If the principal balance of this note is prepaid (only under this LIBOR loan) in whole or in part, whether by voluntary prepayment, operation of law, acceleration or otherwise, a prepayment fee, in addition to any interest earned, will be immediately payable to the holder of this note. The amount of the prepayment fee depends on the following: (1) The amount by which interest reference rates as defined below have changed between the time the loan is prepaid and either a) the time the loan was made for fixed rate loans, or b) the time the interest rate last changed (repriced) for variable rate loans. (2) A prepayment fee factor (see "Prepayment Fee Factor Schedule" on reverse). (3) The amount of principal prepaid. If the proceeds from a CD or time deposit pledged to secure the loan are used to prepay the loan resulting in payment of an early withdrawal penalty for the CD, a prepayment fee will not also be charged under the loan. DEFINITION OF REFERENCE RATE FOR VARIABLE RATE LOANS The "Reference Rate" used to represent interest rate levels for variable rate loans shall be the index rate used to determine the rate on this loan having maturities equivalent to the remaining period to interest rate change date (repricing) of this loan rounded upward to the nearest month. The "Initial Reference Rate" shall be the Reference Rate at the time of last repricing and a new Initial Reference Rate shall be assigned at each subsequent repricing. The "Final Reference Rate" shall be the Reference Rate at the time of prepayment. CALCULATION OF PREPAYMENT FEE If the Initial Reference Rate is less than or equal to the Final Reference Rate, there is no prepayment fee. If the Initial Reference Rate is greater than the Final Reference Rate, the prepayment fee shall be equal to the difference between the Initial and Final Reference Rates (expressed as a decimal), multiplied by the appropriate factor from the Prepayment Fee Factor Schedule, multiplied by the principal amount of the loan being prepaid. EXAMPLE OF PREPAYMENT FEE CALCULATION VARIABLE RATE LOAN: A non-amortizing 6-month LIBOR based loan with principal of $250,000 is fully prepaid with 3 months remaining until next interest rate change date (repricing). An Initial Reference Rate of 7.0% was assigned to the loan at last repricing. The Final Reference Rate (as determined by the 3-month LIBOR index) is 6.5%. Rates therefore have dropped 0.5% since last repricing and a prepayment fee applies. A prepayment fee factor of 0.31 is determined from Table 3 below and the prepayment fee is computed as follows: Prepayment Fee = (0.07 - 0.065) x (0.31) x ($250,000) = $387.50 TABLE III: NONAMORTIZING (INTEREST ONLY) LOANS Proportion of Remaining Principal Amount Being Prepaid Months Remaining To Maturity/Repricing(1) 0 3 6 9 12 24 36 48 60 84 120 240 360 0-100% 0 .31 .61 .91 1.21 2.3 3.4 4.4 5.3 6.9 8.9 13.0 14.8 (1) For the remaining period to maturity/repricing between any two maturities/repricings shown in the above schedules, interpolate between the corresponding factors to the closest month. The holder of this note is not required to actually reinvest the prepaid principal in any U.S. Government Treasury Obligations, or otherwise prove its actual loss, as a condition to receiving a prepayment fee as calculated above.
