Forthwith upon the execution and delivery of this Supplement, or from time to time thereafter, Series C Notes up to a maximum aggregate principal amount of $14,300,000 may be executed by the Company and delivered to the Trustee for authentication, and shall thereupon be authenticated and delivered by the Trustee upon Company order and compliance with Articles 9 and 14 of the Indenture, without any further action by the Company. The Series C Notes issued hereunder will rank pari passu with the Initial Notes and any Notes issued by the Company in the future. The Series C Notes Stated Maturity shall be September 15, 1999 and they shall bear interest at the rate of 10% per annum from their Date of Issue or from the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be, payable semiannually on September 15 and March 15, commencing March 15, 1997, until the principal thereof is paid or duly provided for. The Holder of any Series C Note at the close of business on any record date (as hereinafter defined) with respect to any Interest Payment Date shall be entitled to receive the interest payable thereon on such Interest Payment Date notwithstanding the cancellation of such Note upon any transfer or exchange thereof subsequent to such record date and prior to such Interest Payment Date. With respect to the payment of interest in default, interest shall be paid to the Person in whose name the Series C Note is registered, on a special record date, established at the -2- 5 election of the Company and which shall be not less than five Business Days preceding the date of payment of such defaulted interest, established for such purpose by notice given by, or on behalf of, the Company to the Holders not less than ten Business Days preceding the date so established. The term "record date" as used herein with respect to any Interest Payment Date (other than any date on which defaulted interest is paid) shall mean the September 1 or March 1 (or if that day is not a Business Day, the next preceding Business Day) next preceding such Interest Payment Date. The principal (and premium, if any) of and interest on the Series C Notes shall be payable at the office or agency of the Company in Phoenix, Arizona; provided, however, that interest may be payable at the option of the Company by check mailed to the address of the person entitled thereto as such address shall appear on the Note Register.

The Series C Notes shall be senior in right of payment to all Subordinated Indebtedness of the Company. Each individual holder of Series C Notes will be entitled, at such holder's option, at any time following the issuance of the Series C Notes through the close of business on the final maturity date of the Series C Notes, subject to prior redemption, to fix a conversion price equal to 103% of the average closing price of the Common Stock as quoted on the New York Stock Exchange ("NYSE") for the ten (10) consecutive trading days preceding the date on which the conversion price is fixed by notice to the Company from the Noteholder (the "Conversion Price"). Notice fixing the Conversion Price must be given to the Company in writing, by fax and/or registered letter. Subsequent to fixing the Conversion Price as outlined above, each individual holder of Series C Notes will be entitled, at such holder's option, at any time through the close of business on the final maturity date of the Series C Notes, subject to prior redemption, to convert the Series C Notes in whole, and all accrued interest payable thereon, into Common Stock of the Company, at the Conversion Price. Notice of the conversion must be given in writing to the Company and the holder's Series C Note must be tendered to the Company with the information completed as provided on the form attached to the Series C Note. No fractional shares will be issued. In lieu thereof, the Company will pay cash for fractional share amounts equal to the fair market value of the Common Stock as quoted as the closing price on the NYSE on the date of conversion. If any Notes not called for redemption are converted after a record date for the payment of interest and prior to the next succeeding interest payment date, such Notes must be accompanied by funds equal to the interest payable on such succeeding interest payment date on the principal amount so converted. No such payment will be required if the Company exercises its right to such Notes on a redemption date that is an interest payment date. In the case of Notes called for redemption, conversion rights will expire at the close of business on the business day preceding the day fixed for redemption unless the Company defaults in payment of the redemption price. The Conversion Price is subject to adjustment upon the occurrence of certain events, including: (i) the issuance of Common Stock as a dividend or distribution on Common Stock of the Company; (ii) the issuance of Common Stock pursuant to a stock split; (iii) the issuance to all holders of Common Stock of -3- 6 rights or warrants to purchase Common Stock; and (iv) other subdivisions and combinations of the Common Stock, or other changes affecting the outstanding Common Stock of the Company as a class without the Company's receipt of consideration. If not earlier converted, the Notes are redeemable at the option of the Company in whole or in part on a pro rata basis, at par value plus accrued interest payable through the redemption date, upon thirty (30) days' written notice to the Noteholders in accordance with the following: (i) from September 12, 1996 until June 15, 1997, the Notes may be redeemed by the Company after the closing price of the Company's Common Stock as quoted on the NYSE has equaled or exceeded $25.00 for any ten (10) consecutive trading days, and (ii) after June 15, 1997, the Notes may be redeemed by the Company at any time at par value plus all accrued interest payable through the date of redemption. The Noteholders will have the right to convert their Notes at any time until the close of business on the date fixed for redemption. The redemption price will be paid within forty-eight (48) hours of the redemption date. If less than all of the Notes are to be redeemed in the case of any redemption by the Company, the Trustee shall select the Notes or the portion thereof to be redeemed, by lot or by any other method the Trustee shall deem fair and reasonable. 2.5 Denominations.
