The Bonds of 5 3/4% Series due 2010 are subject to redemption in whole, but not in part, at any time, at the option of the Company upon payment of a redemption price equal to 100% of the principal amount thereof plus accrued interest to the redemption date, without premium, upon the occurrence of any of the following events: (a) damage or destruction to the Company's Chalk Point Generating Station in Maryland (the "Plant") or the pollution control project at the Plant (the "Facilities") to such extent that in the opinion of both the Company's board of directors (expressed in a resolution) and an architect or engineer ac- ceptable to NationsBank, N.A., (the "Pollution Control Bond Trustee"), as trustee under the Indenture of Trust, dated as of March 15, 1995 (the "Pol- lution Control Bond Indenture") between Prince George's County, Maryland (the "County") and the Pollution Control Bond Trustee, both opinions filed with the County and the Pollution Control Bond Trustee, (1) the Plant or the Facilities, as the case may be, cannot be reasonably repaired, rebuilt or restored within a period of six months to its condition immediately preced- ing such damage or destruction, or (2) the Company is thereby prevented from carrying on its normal operations at the Plant for a period of six months; or (b) loss of title to or use of a substantial part of the Plant or the Fa- cilities as a result of the exercise of the power of eminent domain which, in the opinion of both the Company's board of directors (expressed in a res- olution) and an architect or engineer acceptable to the Pollution Control Bond Trustee, both opinions filed with the County and the Pollution Control Bond Trustee, results or is likely to result in the Company thereby being prevented from carrying on its normal operations therein for a period of six months; or 12 (c) a change in the Constitution of the State of Maryland or the Constitu- tion of the United States of America or legislative or administrative action (whether local, state or Federal) or a final decree, judgment or order of any court or administrative body (whether local, state or Federal) which causes the Loan Agreement, dated as of March 15, 1995, between the Company and the County (the "Loan Agreement"), to become void or unenforceable or impossible of performance in accordance with the intent and purpose of the parties as expressed therein or unreasonable burdens or excessive liabili- ties to be imposed upon the County or the Company with respect to the Plant or the Facilities or the operation thereof, including but not limited to the imposition of Federal, state or other ad valorem property, income or other taxes other than ad valorem taxes presently levied upon privately owned property used for the same general purpose as the Facilities; or (d) changes in the economic availability of raw materials, operating sup- plies, energy sources or supplies, or facilities necessary for the operation of the Facilities for the purposes of pollution control "facilities" as de- fined in the Maryland Economic Development Revenue Bond Act, or necessary for the operation of the Plant, occur or such technological or other changes which the Company cannot reasonably overcome or control and which in the reasonable judgment of the Company's board of directors (expressed in a res- olution) render the Facilities or the Plant uneconomic or obsolete for such purposes; or (e) any court or administrative body shall enter a judgment, order or de- cree, or shall take administrative action, requiring the Company to cease all or any substantial part of its operation serviced by the Facilities to the extent the Company is or will be prevented from carrying on its normal operations at the Plant for a period of six months; provided, however, that to exercise such option to redeem the Company shall, file the required resolutions and opinions or a certificate, as the case may be, within nine months after the event permitting its exercise, giving notice to the County and the Pollution Control Bond Trustee, and shall specify a date not less than 45 nor more than 90 days thereafter for redemption. The Bonds of 5 3/4% Series due 2010 are subject to mandatory redemption at any time as a whole or, as hereinafter provided, in part at 100% of the prin- cipal amount thereof plus accrued interest to the redemption date, without premium, in the event that the Pollution Control Bond Trustee shall (a) de- liver a notification to the Trustee and the Company 13 that it has been finally determined by the Internal Revenue Service or a court of competent jurisdiction that, as a result of a failure by the Company to ob- serve any covenant or agreement in the Loan Agreement or contravening any rep- resentation contained in the Loan Agreement, the interest payable on the Pol- lution Control Bonds, 1995 Series issued pursuant to the Pollution Control Bond Indenture is includable for Federal income tax purposes in the gross in- come of any holder of a Pollution Control Bond, 1995 Series, other than a holder who is a "substantial user" of the Facilities or a "related person," as provided in Section 147(a) of the Internal Revenue Code of 1986, as amended, or any applicable predecessor statutory provisions and (b) in conjunction therewith, make a demand for such redemption. No such determination will be considered final for the purpose of any mandatory redemption pursuant to this paragraph unless the Company shall have been given written notice as provided in the Pollution Control Bond Indenture and, if it shall have so desired, been afforded the opportunity to contest the same, either directly or in the name of any holder of a Pollution Control Bond, 1995 Series, and until conclusion of any appellate review with respect thereto, if sought. Any such redemption shall be on any date within 120 days from the time of such final determina- tion. Upon the finality of such determination, the Bonds of 5 3/4% Series due 2010 shall be redeemed in whole unless, as a result of an opinion rendered by Bond Counsel (as defined in the Pollution Control Bond Indenture) pursuant to Section 2.05(b) of the Pollution Control Bond Indenture, the Pollution Control Bonds shall be redeemed only in part, in which event an equal principal amount of Bonds of 5 3/4% Series due 2010 shall also be redeemed. If such redemption shall occur in accordance with the terms hereof, then such failure by the Com- pany to observe such covenant, agreement or representation in the Loan Agree- ment shall not in and of itself constitute an Event of Default under the Pol- lution Control Bond Indenture, the Bonds of 5 3/4% Series due 2010, the Amended Indenture or the Supplemental Indenture of March 10, 1995. The Bonds of 5 3/4% Series due 2010 are also subject to mandatory redemption at any time, as a whole, at 100% of the principal amount thereof plus accrued interest to the redemption date, without premium in the event the Trustee shall receive a written demand (hereinafter called "Default Redemption De- mand") from the Pollution Control Bond 14 Trustee for redemption stating that the principal of all Pollution Control Bonds, 1995 Series then outstanding under the Pollution Control Bond Indenture has been declared to be immediately due and payable pursuant to the provisions of Section 9.01 thereof. The Trustee shall within 10 days of receiving the De- fault Redemption Demand mail a copy to the Company stamped or otherwise marked to show the date of receipt by the Trustee. The Company shall fix a redemption date and shall mail the Trustee notice of such selection at least 15 days prior to the date so selected. Such redemption date may be any day not more than 60 days after the receipt of the Default Redemption Demand by the Trust- ee. If the Trustee does not receive notice of such selection by the Company within 45 days after the Default Redemption Demand was received by the Trust- ee, then the redemption date shall be the 60th day after such receipt. The Trustee shall mail notice of the redemption date (hereinafter called the "De- fault Redemption Notice") to the Pollution Control Bond Trustee not more than 10 nor less than 5 days prior to the date fixed for redemption. The Trustee shall not mail any Default Redemption Notice (and no such redemption shall be made) if the Trustee receives a written cancellation of the Default Redemption Demand from the Pollution Control Bond Trustee prior to the mailing of the De- fault Redemption Notice. Notwithstanding any other provision contained in this Bond, or the Amended Indenture, the holder of this Bond by the acceptance of such Bond hereby waives any longer notice of redemption. In case an event of default, as defined in the Amended Indenture, shall oc- cur, the principal of all the Bonds at any such time outstanding under the Amended Indenture may be declared or may become due and payable, upon the con- ditions and in the manner and with the effect provided in the Amended Inden- ture. The Amended Indenture provides that such declaration may in certain events be waived by the holders of a majority in principal amount of the Bonds entitled to vote then outstanding. Subject to the restriction on transfer appearing hereon, this Bond is trans- ferable by the registered owner hereof, in person or by duly authorized attor- ney, on the books of the Company to be kept for that purpose at the agency of the Company in the City of Washington, D.C., upon 15 surrender and cancellation of this Bond and on presentation of a duly executed written instrument of transfer, and thereupon a new Bond or Bonds of the same series, of the same aggregate principal amount and in authorized denominations will be issued to the transferee in exchange therefor; and this Bond, with or without others of the same series, may in like manner be exchanged for one or more new Bonds of the same series of other authorized denominations but of the same aggregate principal amount; all subject to the terms and conditions set forth in the Amended Indenture. No recourse shall be had for the payment of the principal of, or the interest on, this Bond, or for any claim based hereon or otherwise in respect hereof or of the Amended Indenture or any indenture supplemental thereto, against any incorporator, or against any stockholder, director or officer, past, present or future, of the Company or of any predecessor or successor corporation, ei- ther directly or through the Company or any such predecessor or successor cor- poration, whether for amounts unpaid on stock subscriptions or by virtue of any constitution, statute or rule of law, or by the enforcement of any assess- ment or penalty or otherwise, all such liability, whether at common law, in equity, by any constitution, statute or otherwise, of incorporators, stock- holders, directors or officers being released by every owner hereof by the ac- ceptance of this Bond and as part of the consideration for the issue hereof, and being likewise released by the terms of the Amended Indenture. This Bond shall not be entitled to any benefit under the Amended Indenture or any indenture supplemental thereto, or become valid or obligatory for any pur- pose, until The Riggs National Bank of Washington, D.C., the Trustee under the Amended Indenture, or a successor trustee thereto under the Amended Indenture, shall have signed the form of certificate endorsed hereon. 16 In Witness Whereof, Potomac Electric Power Company has caused this Bond to be signed in its name by the signature (or a facsimile thereof) of its President or a Vice President, and its corporate seal (or a facsimile thereof) to be hereto affixed and attested by the facsimile signature of its Secretary or an Assistant Secretary.
