Exhibit 5(a) April 7, 1998 HoldCo, Inc. 83 Edison Drive Augusta, Maine 04336 Ladies and Gentlemen: I have acted as counsel to HoldCo, Inc., a Maine corporation (the "Company"), in connection with the proposed formation of a holding company structure for Central Maine Power Company, a Maine corporation ("Central Maine"), through the merger (the "Merger") of a wholly-owned subsidiary of the Company ("MergeCo") and Central Maine, pursuant to an Agreement and Plan of Merger (the "Merger Agreement"). This opinion is being rendered in connection with the filing by the Company of a Registration Statement on Form S-4 (the "Registration Statement") relating to the registration under the Securities Act of 1933, as amended (the "Act"), of 35,000,000 shares of Common Stock, $5.00 par value, of the Company (the "Company Common Stock") to be issued in the Merger. For purposes of this opinion, I have examined originals or copies, certified or otherwise identified to my satisfaction, of (i) the Merger Agreement; (ii) the Registration Statement; (iii) the Articles of Incorporation of the Company, as in effect on the date hereof and as to be amended immediately prior to consummation of the Merger; (iv) the By-Laws of the Company to be in effect immediately prior to consummation of the Merger; (v) resolutions adopted by the Board of Directors of the Company relating to the Merger and the issuance and delivery of the Company Common Stock in connection therewith; and (vi) such other documents, certificates and other records as I have deemed necessary or appropriate. Based upon the foregoing, and subject to the qualifications hereinafter expressed, I am of the opinion that: (1) The Company is validly existing as a corporation under the laws of the State of Maine; and (2) The Company Common Stock will be validly issued, fully paid and non- assessable when (i) the Registration Statement shall have become effective under the Act; (ii) the Company's Board of Directors shall have taken appropriate action to authorize the issuance of the Company Common Stock; (iii) Central Maine shareholders shall have approved the Merger; (iv) Central Maine shall have received all necessary regulatory approvals required to consummate the Merger; and (v) the Merger shall have been consummated in accordance with the terms of the Merger Agreement and the laws of the State of Maine. I am a member of the Maine Bar and do not hold myself out as an expert on the laws of any other State. Except as set forth in paragraph 2(iv) above, my opinions expressed above are limited to the laws of the State of Maine and the Federal laws of the United States. I hereby consent to the filing of this opinion as Exhibit 5(a) to the Registration Statement and to the references made to me under the caption "PROPOSAL NO. 2: APPROVAL OF AGREEMENT AND PLAN OF MERGER -- Legal Opinion" in said Registration Statement and the Proxy Statement and Prospectus constituting a part thereof, and any amendments thereof. I hereby consent to reliance on this opinion with respect to Maine law by LeBoeuf, Lamb, Greene & MacRae, L.L.P. Very truly yours, /s/ Anne M. Pare Anne M. Pare
