However, Warrant holders must surrender their Warrants to the Warrant Agent, as discussed below, to collect the Redemption Price. Holders of Warrants are urged to consult with their own tax, business and other advisors concerning the tax, business and other consequences of the exercise, sale or redemption of their Warrants. MANNER OF EXERCISE OF WARRANTS Warrant holders may exercise the Warrants by properly completing and signing the subscription form on the Warrants including, if required, a signature guarantee from an eligible institution, and mailing or delivering the Warrants to the Warrant Agent, together with a payment of the aggregate exercise price of the Warrants in full (in U.S. dollars) by such holder, to: Computershare Trust Company, Inc. 12039 West Alameda Parkway, Suite Z-2 Lakewood, Colorado 80228 Telephone: (303) 986-5400 Facsimile: (303) 986-2444 or to: Computershare Trust Company, Inc. P.O. Box 1596 Denver, CO 80201-1596 A holder may exercise Warrants in whole or in part, but no Warrants may be exercised for fractional shares of Common Stock. The exercise price will be considered to have been paid only upon clearance of the wire transfer, certified or official bank check, bank draft or money order tendered therefor. All funds received by the Warrant Agent from the exercise of the Warrants will be deposited upon receipt. Pending issuance of certificates representing shares of Common Stock, funds received for the exercise of Warrants will be held in a segregated escrow account. 3 ONCE A HOLDER HAS EXERCISED A WARRANT, THE EXERCISE MAY NOT BE REVOKED. To be accepted, the properly completed Warrants and payment with respect to the exercise price of the Warrants must be received by the Warrant Agent before 5:00 p.m., Denver, Colorado time on August 14, 2000. The instruction accompanying the Warrants should be read carefully and followed in detail. WARRANTS SHOULD BE SENT WITH PAYMENT TO THE WARRANT AGENT. DO NOT SEND WARRANTS TO METRETEK. CERTIFICATES REPRESENTING THE SHARES OF COMMON STOCK SUBSCRIBED FOR WILL BE ISSUED AND DELIVERED AS SOON AS PRACTICABLE AFTER PAYMENT OF THE EXERCISE PRICE OF THE WARRANTS. HOLDERS OF WARRANTS, AS SUCH, WILL NOT HAVE ANY RIGHTS AS STOCKHOLDERS OF THE COMPANY UNTIL STOCK CERTIFICATES REPRESENTING THE SHARES OF COMMON STOCK SUBSCRIBED FOR ARE ISSUED TO THEM. The risk of method of delivery of all documents and payment is on the holders of the Warrants, not Metretek or the Warrant Agent. If the mail is used, it is recommended that payments be made by registered mail, properly insured, return receipt requested, and that a sufficient number of days be allowed to ensure delivery to the Warrant Agent before the expiration of the Warrants.
