ARTICLE III A. At the Effective Time: (1) each share of Company Common Stock issued and outstanding immediately prior to the Effective Time shall be automatically exchanged for one share of IPHC Common Stock, which shares shall thereupon be fully paid and non- assessable; (2) IPHC shall acquire and become the owner and holder of each issued and outstanding share of Company Common Stock so exchanged; (3) each share of IPHC Common Stock issued and outstanding immediately prior to the Effective Time shall be canceled and shall thereupon constitute an authorized and unissued share of IPHC Common Stock; (4) each share of Company Common Stock held under the Dividend Reinvestment and Stock Purchase Plan, the Employee Savings Plan and the 1994 Restricted Stock Plan (including fractional and uncertificated shares) immediately prior to the Effective Time shall be automatically exchanged for a like number of shares (including fractional and uncertificated shares) of IPHC Common Stock, which shares shall be held under the Dividend Reinvestment and Stock Purchase Plan, the Employee Savings Plan and the 1994 Restricted Stock Plan, as the case may be; and (5) the former owners of Company Common Stock shall be entitled only to receive shares of IPHC Common Stock as provided herein.

C. As of the Effective Time, IPHC shall succeed to the Dividend Reinvestment and Stock Purchase Plan as in effect immediately prior to the Effective Time, and the Dividend Reinvestment and Stock Purchase Plan shall be appropriately amended to provide for the issuance and delivery of IPHC Common Stock on and after the Effective Time. D. As of the Effective Time, the Employee Savings Plan and the 1994 Restricted Stock Plan shall be appropriately amended to provide for the issuance and delivery of IPHC Common Stock on and after the Effective Time. ARTICLE IV The filing of the Articles with the Secretary of State and the consummation of the Exchange are subject to the satisfaction of the following conditions precedent: (1) the approval by the shareholders of the Company, to the extent required by the Act, of this Agreement; (2) the approval for listing, upon official notice of issuance, by the New York Stock Exchange, of IPHC Common Stock to be issued and reserved for issuance pursuant to the Exchange; (3) the receipt of such orders, authorizations, approvals or waivers from the Idaho Public Utilities Commission and all other regulatory bodies, boards or agencies as are required in connection with the Exchange, which orders, authorizations, approvals or waivers remain in full force and effect and do not include, in the sole judgment of the Board of Directors of the Company, unacceptable conditions; and (4) the receipt by the Company of a tax opinion of LeBoeuf, Lamb, Greene & MacRae L.L.P. satisfactory to the Board of Directors of the Company to the effect that (a) common shareholders of the Company (i) will recognize no gain or loss in connection with the Exchange, (ii) will have the same basis in their IPHC Common Stock after the Exchange as they had in their Company Common Stock before the Exchange and (iii) will be entitled to include any period that they held Company Common Stock before the Exchange when determining any holding period with respect to IPHC Common Stock received in the Exchange and (b) IPHC will recognize no gain or loss upon its receipt of Company Common Stock in the Exchange. ARTICLE V Following the Effective Time, each holder of an outstanding certificate or certificates theretofore representing shares of Company Common Stock may, but shall not be required to, surrender the same to IPHC for cancellation and reissuance of a new certificate or certificates in such holder's name or for cancellation and transfer, and each holder or transferee will be entitled to receive a certificate or certificates representing the same number of shares of IPHC Common Stock as the shares of Company Common Stock previously represented by the certificate or certificates surrendered. Until so surrendered or presented for transfer, each outstanding certificate which, immediately prior to the Effective Time, represented Company Common Stock shall be deemed and treated for all corporate purposes to represent the ownership of the same number of shares of IPHC Common Stock as though such surrender or transfer and exchange had taken place. The holders of Company Common Stock at the Effective Time shall have no right to have their shares of Company Common Stock transferred on the stock transfer books of the Company, and such stock transfer books shall be deemed to be closed for this purpose at the Effective Time. ARTICLE VI This Agreement may be amended, modified or supplemented, or compliance with any provision or condition hereof may be waived, at any time, by the mutual consent of the Boards of Directors of the Company and of IPHC; provided, however, that no such amendment, modification, supplement or waiver shall be made or effected, if such amendment, modification, supplement or waiver would, in the judgment of the Board of Directors of the Company, materially and adversely affect the shareholders of the Company. Notwithstanding shareholder approval of this Agreement, this Agreement may be terminated and the Exchange and related transactions abandoned at any time prior to the time the Articles are filed with the Secretary of State, if the Board of Directors of the Company determines, in its sole discretion, that consummation of the Exchange would be inadvisable or not in the best interests of the Company or its shareholders. IN WITNESS WHEREOF, each of the Company and IPHC, pursuant to authorization and approval given by its Board of Directors, has caused this Agreement to be executed as of the date first above written.
