The charges included $59.4 for severance costs associated with permanent reductions of hourly-paid and salaried employees, mainly in the Company's U.S. aluminum operations. The remaining $10.8 of the charge was associated with closing several activities, including the manufacture of aluminum rod at the Company's Rockdale, Texas plant. For the year, Alcoa earned $79.3, or 88 cents per share, before charges of $74.5. The charges included $87.2 for severance costs, $11.9 related to new three-year labor agreements covering hourly employees at U.S. aluminum operations and $10.8 for restructuring costs. These charges were partially offset by credits of $26.3 due to a change in the Australian tax rate from 39% to 33% and $9.1 due to the change in the U.S. tax rate. The latter credit related to Alcoa's deferred tax assets in the U.S. Total aluminum product shipments of 2.6 million metric tons were 8% lower than those in 1992. Most of the decline came from a decrease in shipments of aluminum ingot, which fell 18% from cutbacks in capacity by the Company due to lower demand and the oversupply of ingot on world markets. Prices for most products continued to deteriorate during 1993, particularly for aluminum sheet for beverage cans and for primary ingot. The Company has aggressively pursued cost reductions, but the decline in costs has not kept pace with the decline in prices. Improved earnings from Alcoa of Australia and Alcoa Aluminio in Brazil compared with 1992 helped Alcoa remain profitable in 1993. Alcoa's share of earnings in 1993 from the respective companies was $160 and $29. S-2

OTHER On December 1, 1993, Alcoa was served with a subpoena from the Antitrust Division of the U.S. Department of Justice to produce documents to a Federal grand jury in Philadelphia. The Company believes the Government is investigating pricing practices in the market for used beverage cans. The Company and its subsidiary, Alcoa Recycling Company, Inc., are complying with the provisions of the subpoena. USE OF PROCEEDS AND CAPITAL EXPENDITURES The net proceeds from the sale of the Notes will be used to redeem $225 million aggregate principal amount of its deep discount 7% Debentures Due 2011 and for general corporate purposes. At December 31, 1993, total long and short term debt of the Company and its subsidiaries was $1,845.8 million. The Company's expenditures for properties, plants and equipment were $757 million in 1993. The Company anticipates that it will finance its 1994 expenditures and investments from internally generated funds together, if needed, with the proceeds of bank borrowings, the sale of debt and equity securities or all of them. The amount and timing of such additional financings cannot be determined at this time. RATIOS OF EARNINGS TO FIXED CHARGES The ratios of the Company's earnings to fixed charges for the years ended December 31, 1989 through 1993 are 8.24, 4.25, 2.28, 2.17 and 2.18. The ratios include all earnings, before extraordinary items and the cumulative effects of accounting changes, and fixed charges of the Company and its majority owned subsidiaries plus the Company's proportionate share of earnings of 50% owned entities. Earnings have been calculated by adding to net income the provision for taxes on income, amortization of capitalized interest, interest expense and an amount representative of the interest factor in rentals, and have been decreased by the undistributed earnings of entities less than 50% owned, preferred stock dividend requirements of majority owned subsidiaries and the minority interest share in the losses of majority owned subsidiaries without fixed charges of the Company. Fixed charges consist of total interest expense, amortization of debt expense, an amount representative of the interest factor in rentals, interest capitalized and preferred stock dividend requirements of majority owned subsidiaries. CERTAIN TERMS OF THE NOTES The following description of the terms of the Notes offered hereby supplements, and should be read in conjunction with, the statements under "Description of Debt Securities" in the Prospectus. GENERAL The Notes will be limited to $250,000,000 aggregate principal amount, will bear interest from February 8, 1994, at the rate of interest stated on the cover page hereof and will mature on February 1, 2001. Interest will be payable semi-annually on February 1 and August 1 to the persons in whose names the Notes are registered at the close of business on the January 15 or July 15, as the case may be, next preceding such interest payment date. The Notes are not subject to redemption by the Company prior to maturity or to the provisions of any optional or mandatory sinking fund. The Notes are not convertible or exchangeable into any other security of the Company. The Indenture sets forth the conditions under which the Company may enter into a merger or consolidation, or convey, transfer or lease all or substantially all of its assets or properties (see "Description of Debt Securities--Consolidation, Merger and Sale of Assets" in the Prospectus), but the covenants contained therein and the Notes will not afford Holders protection in the event of a sudden decline in credit rating that may result from a recapitalization, restructuring or other highly leveraged transaction. STATUS The Notes will rank pari passu with other unsubordinated indebtedness of the Company. S-3

BOOK-ENTRY SYSTEM The Notes will be issued in the form of one or more fully registered Global Notes (collectively, the "Global Note") which will be deposited with, or on behalf of, The Depository Trust Company, New York, New York, as Depositary, and registered in the name of the Depositary's nominee. So long as the Depositary, or its nominee, is the registered owner of the Global Note, the Depositary or such nominee, as the case may be, will be considered the sole owner or Holder of the Notes, represented by the Global Note, for the purposes of receiving payment on the Notes, receiving notices and for all other purposes under the Indenture and the Notes. Interests in the Global Note will be evidenced only by, and transfers thereof will be effected only through, records maintained by the Depositary and its participants. Except as provided in the Prospectus, owners of beneficial interests in the Global Note will not be entitled to have Notes registered in their names, will not receive or be entitled to receive physical delivery of Notes in definitive form and will not be considered the Holders thereof for any purpose under the Indenture. Accordingly, each person owning a beneficial interest in the Global Note must rely on the procedures of the Depositary and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a Holder under the Indenture. The Company understands that under existing industry practices, in the event that the Company requests any action of Holders or that an owner of a beneficial interest in the Global Note desires to give or take any action which a Holder is entitled to give or take under the Indenture, the Depositary would authorize the participants holding the relevant beneficial interests to give or take such action, and such participants would authorize beneficial owners owning through such participants to give or take such action or would otherwise act upon instructions of beneficial owners owning through them. For a further description of the depositary arrangement with respect to the Global Note, see "Description of Debt Securities--Book-Entry Securities" in the Prospectus. The Depositary has advised the Company that the Depositary is a limited- purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered under the Securities Exchange Act of 1934, as amended. The Depositary was created to hold the securities of its participants and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. The Depositary's participants include securities brokers and dealers (including the Underwriters), banks, trust companies, clearing corporations, and certain other organizations, some of whom (and/or their representatives) own the Depositary. Access to the Depositary's book-entry system is also available to others, such as banks, brokers, dealers and trust companies, that clear through or maintain a custodial relationship with a participant, either directly or indirectly. DEFEASANCE OF CERTAIN OBLIGATIONS The Company may omit to comply with the covenants described under "Description of Debt Securities--Certain Limitations" and the covenant described under "Description of Debt Securities-- Consolidation, Merger and Sale of Assets" in the Prospectus if the conditions set forth under "Description of Debt Securities--Defeasance and Covenant Defeasance" in the Prospectus are satisfied. UNDERWRITING The Underwriters named below have severally agreed to purchase from the Company the following respective principal amounts of the Notes: PRINCIPAL AMOUNT OF UNDERWRITER NOTES ----------- ------------ CS First Boston Corporation....................................... $ 83,400,000 Goldman, Sachs & Co............................................... 83,300,000 Lehman Brothers Inc............................................... 83,300,000 ------------ Total......................................................... $250,000,000 ============ S-4

The Underwriting Agreement provides that the obligations of the Underwriters are subject to certain conditions precedent, and that the Underwriters will be obligated to purchase all of the Notes if any are purchased. The Company has been advised by CS First Boston Corporation, as Representative of the Underwriters, that the Underwriters propose to offer the Notes to the public initially at the offering price set forth on the cover page of this Prospectus Supplement and, through the Representative, to certain dealers at such price less a concession of .375% of the principal amount of the Notes; that the Underwriters and such dealers may allow a discount of .25% of such principal amount on sales to other dealers; and, after the initial public offering, the public offering price and concession and discount to dealers may be changed by the Representative. The Company has agreed to indemnify the several Underwriters against certain civil liabilities, including liabilities under the Securities Act of 1933, as amended. VALIDITY OF THE NOTES The validity of the Notes will be passed upon for the Company by Denis A. Demblowski, Esq., Managing General Attorney and Assistant Secretary of the Company, and for the Underwriters by Sullivan & Cromwell, 125 Broad Street, New York, New York 10004, who will rely as to all matters of Pennsylvania law upon the opinion of Denis A.

The Debt Securities may be issued from time to time in one or more series. The particular terms of each series of Debt Securities offered by any Prospectus Supplement or Prospectus Supplements will be described in such Prospectus Supplement or Prospectus Supplements relating to such series.

(Section 301) Any such Prospectus Supplement will also describe any special provisions for the payment of additional amounts with respect to the Offered Debt Securities. Debt Securities may be issued at a substantial discount below their stated principal amount. Special United States federal income tax considerations applicable to Debt Securities issued at discount and to Debt Securities which are denominated in a currency other than United States dollars are described under "United States Taxation of Debt Securities--United States Holders". Debt Securities may also be issued under the Indenture upon the exercise of Warrants issued by the Company. See "Description of Warrants". United States federal income tax consequences applicable to any Offered Warrants will be set forth in the Prospectus Supplement relating thereto. FORM, EXCHANGE, REGISTRATION AND TRANSFER Securities of a series may be issuable in definitive form solely as Registered Securities, solely as Bearer Securities or as both Registered Securities and Bearer Securities. Unless otherwise indicated in an applicable Prospectus Supplement, definitive Bearer Securities will have interest coupons attached. (Section 201) The Indenture also will provide that Securities of a series may be issuable in temporary and permanent global form. (Section 201) See "Permanent Global Securities." In connection with its sale during the restricted period (as defined under "Limitations on Issues of Bearer Securities"), no Bearer Security (including a Security in permanent global form) shall be mailed or otherwise delivered to any location in the United States or its possessions. No Bearer Security other than a temporary global Bearer Security may be delivered, nor may interest be paid on any Bearer Security unless the Person entitled to receive such Bearer Security or such interest furnishes written certification, in the form required by the Indenture, to the effect that such person (i) is not a United States person (as defined below under "Limitations on Issuance of Bearer Securities"), (ii) is a foreign branch of a United States financial institution purchasing for its own account or for resale, or is a United States person who acquired the Debt Security through such a financial institution and who holds the Debt Security through such financial institution on the date of certification, provided in either case that such financial institution provides a certificate to the 4

Company or the distributor selling the Debt Security to it stating that it agrees to comply with the requirements of Section 165(j)(3)(A), (B) or (C) of the Internal Revenue Code of 1986, as amended (the "Code"), and the United States Treasury Regulations thereunder, or (iii) is a financial institution holding for purposes of resale during the restricted period (as defined in United States Treasury Regulations Section 1.163-5(c)(2)(i)(D)(7)). A financial institution described in clause (iii) of the preceding sentence (whether or not also described in clause (i) or (ii)) must certify that it has not acquired the Debt Security for purposes of resale directly or indirectly to a United States person or to a person within the United States or its possessions. In the case of a Bearer Security in permanent global form, such certification must be given in connection with notation of a beneficial owner's interest therein. (Section 303) See "Temporary Global Securities" and "Limitations on Issuance of Bearer Securities." Registered Securities of any series will be exchangeable for other Registered Securities of the same series and of a like aggregate principal amount and tenor of different authorized denominations. In addition, if Securities of any series are issuable as both Registered Securities and Bearer Securities, at the option of the Holder upon request confirmed in writing, and subject to the terms of the Indenture, Bearer Securities (with all unmatured coupons, except as provided below, and all matured coupons in default) of such series will be exchangeable into Registered Securities of the same series of any authorized denominations and of a like aggregate principal amount and tenor. Bearer Securities surrendered in exchange for Registered Securities between a Regular Record Date or a Special Record Date and the relevant date for payment of interest shall be surrendered without the coupon relating to such date for payment of interest and interest will not be payable in respect of the Registered Security issued in exchange for such Bearer Security, but will be payable only to the Holder of such coupon when due in accordance with the terms of the Indenture. Bearer Securities will not be issued in exchange for Registered Securities. (Section 305) Each Bearer Security other than a temporary global Bearer Security will bear a legend substantially to the following effect: "Any United States Person who holds this obligation will be subject to limitations under the United States income tax laws, including the limitations provided in Sections 165(j) and 1287(a) of the Internal Revenue Code." Securities may be presented for exchange as provided above, and Registered Securities may be presented for registration of transfer (with the form of transfer endorsed thereon duly executed, if so required by the Company or the Trustee or any transfer agent), at the office of the Security Registrar or at the office of any transfer agent designated by the Company for such purpose with respect to any series of Securities and referred to in an applicable Prospectus Supplement, without service charge and upon payment of any taxes and other governmental charges as described in the Indenture. Such transfer or exchange will be effected upon the Security Registrar or such transfer agent, as the case may be, being satisfied with the documents of title and identity of the person making the request. (Section 305) If a Prospectus Supplement refers to any transfer agents (in addition to the Security Registrar) initially designated by the Company with respect to any series of Securities, the Company may at any time rescind the designation of any such transfer agent or approve a change in the location through which any such transfer agent acts, except that, if Securities of a series are issuable solely as Registered Securities, the Company will be required to maintain a transfer agent in each Place of Payment for such series and, if Securities of a series are issuable as Bearer Securities, the Company will be required to maintain (in addition to the Security Registrar) a transfer agent in a Place of Payment for such series located outside the United States. The Company may at any time designate additional transfer agents with respect to any series of Securities. (Section 1002) In the event of any redemption in part, the Company shall not be required to (i) issue, register the transfer of or exchange Securities of any series during a period beginning at the opening of business 15 days before any selection of Securities of that series to be redeemed and ending at the close of business on (A) if Securities of the series are issuable only as Registered Securities, the day of mailing of the relevant notice of redemption and (B) if Securities of the series are issuable as Bearer Securities, the day of the first publication of the relevant notice of redemption or, if Securities of the series are also issuable as Registered Securities and there is no publication, the mailing of the relevant notice of redemption; (ii) register the transfer of or exchange any Registered Security, or portion thereof, called for redemption, except the unredeemed portion of any Registered Security being redeemed in part; or (iii) exchange any Bearer Security called for redemption, except to exchange such Bearer Security for a Registered Security of that series and like tenor which is immediately surrendered for redemption. (Section 305) 5

PAYMENT AND PAYING AGENTS Unless otherwise indicated in an applicable Prospectus Supplement, payment of principal of and any premium and interest on Bearer Securities will be payable, subject to any applicable laws and regulations, at the offices of such Paying Agents outside the United States as the Company may designate from time to time by check or by transfer, at the option of the Holder, to an account maintained by the payee with a bank located outside the United States. Unless otherwise indicated in an applicable Prospectus Supplement, payment of interest on Bearer Securities on any Interest Payment Date will be made only against surrender outside the United States, to the Paying Agent, of the coupon relating to such Interest Payment Date. (Section 1001) No payment with respect to any Bearer Security will be made at any office or agency of the Company in the United States or by check mailed to any address in the United States or by transfer to an account maintained with a bank located in the United States. Notwithstanding the foregoing, payments of principal of and any premium and interest on Bearer Securities denominated and payable in U.S. dollars will be made at the office of the Company's Paying Agent in the Borough of Manhattan, the City of New York, if (but only if) payment of the full amount thereof in U.S. dollars at all offices or agencies outside the United States is illegal or effectively precluded by exchange controls or other similar restrictions. (Section 1002) Unless otherwise indicated in an applicable Prospectus Supplement, payment of principal of and any premium and interest on Registered Securities will be made at the office of such Paying Agent or Paying Agents as the Company may designate from time to time, except that at the option of the Company, payment of any interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. Unless otherwise indicated in an applicable Prospectus Supplement, payment of any instalment of interest on Registered Securities will be made to the Person in whose name such Registered Security is registered at the close of business on the Regular Record Date for such interest. (Section 307) Unless otherwise indicated in an applicable Prospectus Supplement, the Corporate Trust Office of the Trustee in Pittsburgh, Pennsylvania will be designated as a Paying Agent for the Company for payments with respect to Debt Securities which are issuable solely as Registered Securities and the Company will maintain a Paying Agent outside of the United States for payments with respect to Debt Securities (subject to the limitations described above in the case of Bearer Securities) which are issuable solely as Bearer Securities or as both Registered Securities and Bearer Securities. Any Paying Agents outside the United States and any other Paying Agents in the United States initially designated by the Company for the Debt Securities will be named in an applicable Prospectus Supplement. The Company may at any time designate additional Paying Agents or rescind the designation of any Paying Agent or approve a change in the office through which any Paying Agent acts, except that, if Securities of a series are issuable solely as Registered Securities, the Company will be required to maintain a Paying Agent in each Place of Payment for such series and, if Securities of a series are issuable as Bearer Securities, the Company will be required to maintain (i) a Paying Agent in the Borough of Manhattan, the City of New York for payments with respect to any Registered Securities of the series (and for payments with respect to Bearer Securities of the series in the circumstances described above, but not otherwise), and (ii) a Paying Agent in a Place of Payment located outside the United States where Securities of such series and any coupons appertaining thereto may be presented and surrendered for payment; provided that if the Securities of such series are listed on The Stock Exchange of the United Kingdom and the Republic of Ireland or the Luxembourg Stock Exchange or any other stock exchange located outside the United States and such stock exchange shall so require, the Company will maintain a Paying Agent in London or Luxembourg or any other required city located outside the United States, as the case may be, for the Securities of such series. (Section 1002) All moneys paid by the Company to a Paying Agent for the payment of principal of and any premium or interest on any Security which remain unclaimed at the end of two years after such principal, premium or interest shall have become due and payable will be repaid to the Company and the Holder of such Security or any coupon will thereafter look only to the Company for payment thereof. (Section 1003) 6

BOOK-ENTRY SECURITIES The Securities of a series may be issued in the form of one or more Registered Securities that will be registered in the name of the Depositary or its nominee and bearing a legend as specified in the Indenture ("Book-Entry Security"). Unless otherwise indicated in the applicable Prospectus Supplement, a Book-Entry Security may not be registered for transfer or exchange to any Person other than the Depositary or its nominee unless (i) the Depositary notifies the Company that it is unwilling to continue as Depositary or ceases to be a clearing agency registered under the Exchange Act, (ii) the Company executes and delivers to the Trustee a Company Order that such Book-Entry Security shall be so exchangeable and the transfer thereof so registrable, or (iii) there shall have occurred and be continuing an Event of Default, or an event which after notice or lapse of time, or both, would be an Event of Default, with respect to the Securities evidenced by such Book-Entry Security. Upon the occurrence in respect of any Book-Entry Security of any series of any one or more of the conditions specified in clauses (i) , (ii) or (iii) of the preceding sentence or such other conditions as may be specified as contemplated by the Indenture for such series, such Book-Entry Security may be exchanged for Securities of such series registered in the names of, and the transfer of such Book-Entry Security may be registered to, such Persons (including Persons other than the Depositary with respect to such series and its nominees) as such Depositary shall direct. The specific terms of the depositary arrangement with respect to any portion of a series of Registered Book-Entry Securities to be represented by a Book- Entry Security will be described in the applicable Prospectus Supplement. The Company expects that the following provisions will apply to depositary arrangements. Unless otherwise specified in the applicable Prospectus Supplement, Securities which are to be represented by a Book-Entry Security to be deposited with or on behalf of a Depositary will be represented by a Book-Entry Security registered in the name of such Depositary or its nominee. Upon the issuance of such Book-Entry Security, and the deposit of such Book-Entry Security with or on behalf of the Depositary for such Book-Entry Security, the Depositary will credit, on its book-entry registration and transfer system, the respective principal amounts of the Securities represented by such Book-Entry Security to the accounts of institutions that have accounts with such Depositary or its nominee ("participants"). The accounts to be credited will be designated by the underwriters or agents of such Securities or by the Company if such Securities are offered and sold directly by the Company. Ownership of beneficial interests in such Book-Entry Security will be limited to participants or Persons that may hold interests through participants. Ownership of beneficial interests by participants in such Book-Entry Security will be shown on, and the transfer of that ownership interest will be effected only through, records maintained by the Depositary or its nominee for such Book-Entry Security. Ownership of beneficial interests in such Book-Entry Security by Persons that hold through participants will be shown on, and the transfer of that ownership interest within such participant will be effected only through, records maintained by such participant. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in certificated form. The foregoing limitations and such laws may impair the ability to transfer beneficial interests in such Book-Entry Securities. So long as the Depositary for a Book-Entry Security, or its nominee, is the registered owner of such Book-Entry Security, such Depositary or such nominee, as the case may be, will be considered the sole owner or Holder of the Securities represented by such Book-Entry Security for all purposes under the Indenture. Unless otherwise specified in the applicable Prospectus Supplement, owners of beneficial interests in such Book-Entry Security will not be entitled to have Securities of the series represented by such Book-Entry Security registered in their names, will not receive or be entitled to receive physical delivery of Securities of such series in certificated form and will not be considered the Holders thereof for any purposes under the Indenture. (Sections 204 and 305) Accordingly, each Person owning a beneficial interest in such Book-Entry Security must rely on the procedures of the Depositary and, if such Person is not a participant, on the procedures of the participant through which such Person owns its interest, to exercise any rights of a Holder under the Indenture. The Indenture provides that the Depositary may grant proxies and otherwise authorize participants to give or take any request, demand, authorization, direction, notice, consent, waiver or other action which a Holder is entitled to give or take under the Indenture. (Section 104) The Company understands that under existing industry practices, if the Company requests any action of Holders, or an 7

owner of a beneficial interest in such Book-Entry Security desires to give any notice or take any action a Holder is entitled to give or take under the Indenture, the Depositary would authorize the participants to give such notice or take such action, and participants would authorize beneficial owners owning through such participants to give such notice or take such action or would otherwise act upon the instructions of beneficial owners owning through them. TEMPORARY GLOBAL SECURITIES If so specified in an applicable Prospectus Supplement, all or any portion of the Securities of a series which are issuable as Bearer Securities will initially be represented by one or more temporary global Securities, without interest coupons, to be deposited with a common depositary in London for the Euro-clear System ("Euro-clear") and CEDEL S.A. ("CEDEL") for credit to the designated accounts. On and after the date determined as provided in any such temporary global Security and described in an applicable Prospectus Supplement, each such temporary global Security will be exchanged for an interest in a permanent global Bearer Security as specified in an applicable Prospectus Supplement, but, unless otherwise specified in an applicable Prospectus Supplement, only upon receipt of written certification from Euro-clear or CEDEL, as the case may be, in the form and to the effect required by the Indenture (a "Depositary Tax Certification") and upon receipt of written certification by Euro-clear or CEDEL from the person entitled to receive such Securities in the form and to the effect described under "Form, Exchange, Registration and Transfer." No definitive Bearer Security (including a Security in permanent global form that is either a Bearer Security or exchangeable for Bearer Securities) delivered in exchange for a portion of a temporary or permanent global Security shall be mailed or otherwise delivered to any location in the United States in connection with such exchange. (Section 304) Unless otherwise specified in an applicable Prospectus Supplement, interest in respect of any portion of a temporary global Security payable in respect of an Interest Payment Date occurring prior to the issuance of securities in permanent global form will be paid to each of Euro-clear and CEDEL with respect to the portion of the temporary global Security held for its account following the receipt by the Company or its agent of a Depositary Tax Certification. Each of Euro-clear and CEDEL will undertake in such circumstances to credit such interest received by it in respect of a temporary global Security to the respective accounts for which it holds such temporary global Security only upon receipt in each case of certification in the form and to the effect described under "Form, Exchange, Registration and Transfer" with respect to the portion of such temporary global Security on which such interest is to be so credited. Receipt of the certification described in the preceding sentence by Euro-clear or CEDEL, as the case may be, shall constitute irrevocable instructions to Euro-clear or CEDEL to exchange such portion of the temporary global Security with respect to which such certification was received for an interest in a permanent global security. PERMANENT GLOBAL SECURITIES If any Securities of a series are issuable in permanent global form, the applicable Prospectus Supplement will describe the circumstances, if any, under which beneficial owners of interests in any such permanent global Security may exchange such interests for Securities of such series and of like tenor and principal amount in any authorized form and denomination. No Bearer Security delivered in exchange for a portion of a permanent global Security shall be mailed or otherwise delivered to any location in the United States in connection with such exchange. (Section 305) A Person having a beneficial interest in a permanent global Security will, except with respect to payment of principal of and any premium and interest on such permanent global Security, be treated as a Holder of such principal amount of Outstanding Securities represented by such permanent global Security as shall be specified in a written statement of the Holder of such permanent global Security or, in the case of a permanent global Security in bearer form, of the operator of Euro- clear or CEDEL which is produced to the Trustee by such Person. (Section 203) Principal of and any premium and interest on a permanent global Security will be payable in the manner described in the applicable Prospectus Supplement. 8

(Section 1009) Sale and Leaseback Arrangements. The Company covenants that it will not, nor will it permit any Restricted Subsidiary to, enter into any arrangement with any person that provides for the leasing to the Company or any Restricted Subsidiary of Principal Property (other than any such transaction involving a lease for a term of not more than three years or any such transaction between the Company and a Restricted Subsidiary or between Restricted Subsidiaries) which has been or is to be sold or transferred by the Company or such Restricted Subsidiary to such person, unless either (a) the Company or such Restricted Subsidiary would be entitled to create, incur, assume or guarantee Debt secured by a mortgage on such Principal Property at least equal in amount to the Attributable Debt with respect to such arrangement, without equally and ratably securing the Debt Securities, pursuant to the limitation in the Indenture on liens, or (b) the Company shall apply an amount equal to the greater of the net proceeds of such sale or the Attributable Debt with respect to such arrangement to the retirement of Debt that matures more than twelve months after the creation of such Debt. (Section 1010) CERTAIN DEFINITIONS The term "Affiliate" of any specified Person shall mean any other Person directly or indirectly controlling or controlled by or under direct or indirect common control with such specified Person.

Common Stock, (d) distributions to all holders of Common Stock of shares of any class of capital stock, evidences of indebtedness of the Company or assets (including securities, but excluding those dividends and distributions referred to above, any rights, options and warrants, and any dividends or distributions paid exclusively in cash), (e) distributions consisting exclusively of cash to all holders of Common Stock in an aggregate amount that, together with (i) other all-cash distributions made within the preceding 12 months to all holders of Common Stock and (ii) any cash and the fair market value of other consideration paid in respect of any tender offer by the Company or any of its subsidiaries for the Company's Common Stock concluded within the preceding 12 months, exceeds 12.5% of the Company's then current market capitalization (being the product of the current market price per share (as defined) of the Common Stock times the number of shares of Common Stock then outstanding), (f) the successful completion of a tender offer made by the Company or any of its subsidiaries for the Company's Common Stock which involves an aggregate consideration that, together with (i) any cash and other consideration paid in respect of any tender offer by the Company or any of its subsidiaries for the Company's Common Stock expiring within the 12 months preceding the expiration of such tender offer and (ii) the aggregate amount of any all-cash distributions to all holders of the Company's Common Stock within the 12 months preceding the expiration of such tender offer, exceeds 12.5% of the Company's then current market capitalization (being the product of the then current market price per share (as defined) of the Common Stock times the number of shares of Common Stock then outstanding) at the expiration of such tender offer, and (g) certain reclassifications. No adjustment of the conversion price will be required unless an adjustment would require a cumulative increase or decrease of at least 1% of such price; provided, however, that any adjustment that would otherwise be required to be made shall be carried forward and taken into account in a subsequent adjustment. No adjustment of the conversion price will result in zero or in a negative number or will reduce the conversion price below the then par value of the Common Stock (in which case the conversion price would be reduced to such par value), unless the Common Stock has no par value at such time (in which case the conversion price would be reduced to $.01 per share). (Section 1504) If the Company distributes any rights, options or warrants (other than those referred to in clause (b) of the preceding paragraph) ("Rights") to all holders of Common Stock, in lieu of a conversion price reduction, each holder who converts after the record date for the distribution and prior to the expiration or redemption of the Rights will be entitled to receive, in addition to the shares of Common Stock issuable upon such conversion, the same number of Rights to which a holder of the number of shares of Common Stock into which the principal amount of the security so converted was convertible would have been entitled. In addition to the foregoing adjustments, the Company, at its option, will be permitted to make such reductions in the conversion price as it considers to be advisable (including such reductions in the conversion price as it considers advisable in order that any event treated for federal income tax purposes as a dividend of stock or stock rights will not be taxable to the holders of the Common Stock). In case of certain consolidations or mergers to which the Company is a party or the transfer of the property and the assets of the Company substantially as an entirety, each Outstanding Security would, without the consent of any Holder of the Securities, become convertible only into the kind and amount of securities, cash and other property receivable upon the consolidation, merger, sale or transfer by a holder of the number of shares of Common Stock into which such Security might have been converted immediately prior to such consolidation, merger, sale or transfer (assuming such holder of Common Stock failed to exercise any rights of election and received per share the kind and amount received per share by a plurality of non-electing shares). (Section 1512) Fractional shares of Common Stock will not be issued upon conversion, but, in lieu thereof, the Company will pay a cash adjustment based upon the market price of the Common Stock. (Section 1503) Securities surrendered for conversion during the period from the close of business on any Regular Record Date next preceding any Interest Payment Date to the opening of business on such Interest Payment Date (except the securities of any series called for redemption during such period) must be accompanied by payment of an amount equal to the interest thereon which the registered Holder is to receive. In the case of any Security which has been converted after any Regular Record Date but on or before the next Interest Payment Date (except Securities of any series whose Maturity is prior to such Interest Payment Date), interest whose Stated Maturity is on such Interest Payment Date will be payable on such Interest Payment Date notwithstanding 14

such conversion, and such interest shall be paid to the Holder of such Note on such Regular Record Date. Except as described above, no interest on converted Securities will be payable by the Company on any Interest Payment Date subsequent to the date of conversion. No other payment or adjustment for interest or dividends is to be made upon conversion. (Sections 1507 and 1502) DEFEASANCE AND COVENANT DEFEASANCE Unless otherwise indicated in the applicable Prospectus Supplement with respect to the Securities of a series, the Company, at its option, (i) will be discharged from any and all obligations in respect of the Securities of such series (except for certain obligations to issue temporary Securities pending preparation of definitive Securities, to register the transfer or exchange of Securities of such series, to replace stolen, lost or mutilated Securities of such series, and to maintain paying agents and hold moneys for payment in trust) or (ii) need not comply with the covenants that are set forth under "Certain Limitations" and "Consolidations, Mergers and Sale of Assets," and the occurrence of an event described under clause (d) of the "Events of Default" with respect to any defeased covenant and Clauses (e) and (g) of the "Events of Default" shall no longer be an Event of Default if, in each case, the Company irrevocably deposits with the Trustee, in trust, money and/or U.S. Government Obligations that through the scheduled payment of interest thereon and principal thereof in accordance with their terms will provide money in an amount sufficient to pay all the principal of (and premium, if any) and any interest on the Securities of such series on the dates such payments are due (which may include one or more redemption dates designated by the Company) in accordance with the terms of the Indenture and such Securities. Such a trust may only be established if, among other things, (a) no Event of Default or event which with the giving of notice or lapse of time, or both, would become an Event of Default under the Indenture shall have occurred and be continuing on the date of such deposit, or with regard to any Event of Default or any such event described under clause (f) of "Events of Default" shall have occurred and be continuing at any time during the period ending on the 91st day following such date of deposit, and (b) the Company shall have delivered an Opinion of Counsel based, in the event of a defeasance of the type described in clause (i) above, upon a ruling from the Internal Revenue Service or a change in applicable Federal income tax law from the date of the Indenture to the effect that the Holders of the Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such deposit or defeasance and will be subject to Federal income tax in the same manner as if such defeasance had not occurred. In the event the Company omits to comply with its remaining obligations under the Indenture after a defeasance of the Indenture with respect to the Securities of any series as described under clause (ii) above and the Securities of such series are declared due and payable because of the occurrence of any undefeased Event of Default, the amount of money and/or U.S. Government Obligations on deposit with the Trustee may be insufficient to pay amounts due on the Securities of such series at the time of the acceleration resulting from such Event of Default. However, the Company will remain liable in respect of such payments. (Article Thirteen) MEETINGS, MODIFICATION AND WAIVER Modifications and amendments of the Indenture may be made by the Company and the Trustee with the consent of the Holders of not less than 66 2/3% in aggregate principal amount of the Outstanding Securities of each series affected by such modification or amendment; provided, however, that no such modification or amendment may, without the consent of the Holder of each Outstanding Security affected thereby, (a) change the Stated Maturity of the principal of, or any instalment of principal of or interest on any Security, (b) reduce the principal amount of, or premium or interest on, any Security, (c) change any obligation of the Company to pay additional amounts, (d) reduce the amount of principal of an Original Issue Discount Security payable upon acceleration of the Maturity thereof, (e) change the coin or currency in which any Security or any premium or interest thereon is payable, (f) impair the right to institute suit for the enforcement of any payment on or with respect to any Security, (g) reduce the percentage in principal amount of Outstanding Securities of any series, the consent of whose Holders is required for modification or amendment of the Indenture or for waiver of compliance with certain provisions of the Indenture or for waiver of certain defaults, (h) reduce the requirements contained in the Indenture for quorum or voting, (i) change any obligation of the Company to maintain an office or agency in the places and for the purposes required by the Indenture, or (j) modify any of the above provisions. (Section 902) 15

The Holders of at least 66 2/3% of the outstanding Securities of a series may waive compliance by the Company with certain restrictive provisions of the Indenture. (Section 1012) The Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of each series may, on behalf of all Holders of Securities of that series and any coupons appertaining thereto, waive any past default under the Indenture with respect to Securities of that series, except a default (a) in the payment of principal of (or premium if any) or any interest on any Security of such series, and (b) in respect of a covenant or provision of the Indenture which cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. (Section 513) The Indenture will provide that in determining whether the Holders of the requisite principal amount of the Outstanding Securities have given any request, demand, authorization, direction, notice, consent or waiver thereunder or are present at a meeting of Holders of Securities for quorum purposes, (i) the principal amount of an Original Issue Discount Security that shall be deemed to be Outstanding shall be the amount of the principal thereof that would be due and payable as of the date of such determination upon acceleration of the Maturity thereof, (ii) the principal amount of a Security denominated in a foreign currency or currencies shall be the U.S. dollar equivalent, determined on the date of original issuance of such Security, of the principal amount of such Security (or, in the case of an Original Issue Discount Security, the U.S. dollar equivalent, determined on the date of original issuance of such Security, of the amount determined as provided in (i) above), and (iii) Securities owned by the Company or an Affiliate thereof shall not be deemed outstanding. (Section 101) The Indenture will contain provisions for convening meetings of the Holders of Securities of a series if Securities of that series are issuable as Bearer Securities. (Section 1401) A meeting may be called at any time by the Trustee, and also, upon request, by the Company or the Holders of at least 10% in principal amount of the Outstanding Securities of such series, in any such case upon notice given in accordance with "Notices" below. (Section 1402) To be entitled to vote at any meeting of Holders of Securities of any series, a Person shall be (1) a Holder of one or more Outstanding Securities of such series, or (2) a person appointed by an instrument in writing as proxy of a Holder or Holders, including proxies given to beneficial owners of Book-Entry Securities by the Depositary, or its nominee. (Section 1403) Except for any consent which must be given by the Holder of each Outstanding Security affected thereby, as described above, any resolution presented at a meeting or adjourned meeting at which a quorum is present may be adopted by the affirmative vote of the Holders of a majority in principal amount of the Outstanding Securities of that series; provided, however, that, except for any consent which must be given by the Holder of each Outstanding Security affected thereby, as described above, any resolution with respect to any consent or waiver which may be given by the Holders of not less than 66 2/3% in principal amount of the Outstanding Securities of a series may be adopted at a meeting or an adjourned meeting at which a quorum is present only by the affirmative vote of 66 2/3% in principal amount of the Outstanding Securities of that series; and provided, further, that, except for any consent which must be given by the Holder of each Outstanding Security affected thereby, as described above, any resolution with respect to any request, demand, authorization, direction, notice, consent, waiver or other action which may be made, given or taken by the Holders of a specified percentage, which is less than a majority, in principal amount of Outstanding Securities of a series may be adopted at a meeting or adjourned meeting duly reconvened at which a quorum is present by the affirmative vote of the Holders of such specified percentage in principal amount of the Outstanding Securities of that series. Any resolution passed or decision taken at any meeting of Holders of Securities of any series duly held in accordance with the Indenture will be binding on all Holders of Securities of that series and the related coupons. The quorum at any meeting called to adopt a resolution, and at any reconvened meeting, will be persons holding or representing a majority in principal amount of the Outstanding Securities of a series; provided, however, that if any action is to be taken at such meeting with respect to a consent or waiver which may be given by the Holders of not less than 66 2/3% in principal amount of the Outstanding Securities of a series, the persons holding or representing 66 2/3% in principal amount of the Outstanding Securities of such series will constitute a quorum. (Section 1404) 16

CONSOLIDATION, MERGER AND SALE OF ASSETS The Company, without the consent of the Holders of any of the Outstanding Securities under the Indenture, may consolidate or merge with or into, or transfer or lease its assets substantially as an entirety to, any Person which is a corporation, partnership or trust organized and validly existing under the laws of any domestic jurisdiction, or may permit any such Person to consolidate with or merge into the Company or convey, transfer or lease its properties and assets substantially as an entirety to the Company, provided that any successor Person assumes the Company's obligations on the Securities and under the Indenture, that after giving effect to the transaction no Event of Default, and no event which, after notice or lapse of time, would become an Event of Default, shall have occurred and be continuing, and that certain other conditions are met. (Section 801) NOTICES Except as otherwise provided in the Indenture, notices to Holders of Bearer Securities will be given by publication at least twice in a daily newspaper in the City of New York and in such other city or cities as may be specified in such Securities. Notices to Holders of Registered Securities will be given by mail to the addresses of such Holders as they appear in the Security Register. (Sections 101 and 106) TITLE Title to any Bearer Securities and any coupons appertaining thereto will pass by delivery. The Company, the Trustee and any agent of the Company or the Trustee may treat the bearer of any Bearer Security and the bearer of any coupon and the registered owner of any Registered Security as the absolute owner thereof (whether or not such Security or coupon shall be overdue and notwithstanding any notice to the contrary) for the purpose of making payment and for all other purposes. (Section 308) REPLACEMENT OF SECURITIES AND COUPONS Any mutilated Security or a Security with a mutilated coupon appertaining thereto will be replaced by the Company at the expense of the Holder upon surrender of such Security to the Security Registrar. Securities or coupons that become destroyed, stolen or lost will be replaced by the Company at the expense of the Holder upon delivery to the Trustee of the Security and coupons or evidence of the destruction, loss or theft thereof satisfactory to the Company and the Trustee; in the case of any coupon which becomes destroyed, stolen or lost, such coupon will be replaced by issuance of a new Security in exchange for the Security to which such coupon appertains. In the case of a destroyed, lost or stolen Security or coupon, an indemnity satisfactory to the Trustee and the Company may be required at the expense of the Holder of such Security or coupon before a replacement Security will be issued. (Section 306) GOVERNING LAW The Indenture, the Securities and the coupons will be governed by, and construed in accordance with, the laws of the Commonwealth of Pennsylvania. (Section 113) REGARDING THE TRUSTEE PNC Bank, National Association, Trustee under the Indenture, also is trustee under various indentures covering certain other securities of the Company. The Company and certain of its Subsidiaries maintain deposit accounts and conduct other banking transactions, including borrowings in the ordinary course of business, with PNC Bank, National Association. DESCRIPTION OF WARRANTS The Company may issue, together with any Debt Securities offered by any Prospectus Supplement or separately, Warrants for the purchase of other Debt Securities. The Warrants are to be issued under Warrant Agreements (each a "Warrant Agreement") to be entered into between the Company and a bank or trust company, as Warrant Agent (the "Warrant Agent"), all as set forth in the Prospectus Supplement relating to the particular issue of Offered Warrants. A copy of the form of Warrant Agreement, including the form of 17

Warrant Certificates representing the Warrants (the "Warrant Certificates"), reflecting the alternative provisions to be included in the Warrant Agreements that will be entered into with respect to particular offerings of Warrants, is filed as an exhibit to the Registration Statement. The following summaries of certain provisions of the Warrant Agreement and the Warrant Certificates do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all the provisions of the Warrant Agreement and the Warrant Certificates, respectively. GENERAL The Prospectus Supplement will describe the terms of the Offered Warrants, the Warrant Agreement relating to the Offered Warrants and the Warrant Certificates representing the Offered Warrants, including the following: (1) the designation, aggregate principal amount and terms of the Debt Securities purchasable upon exercise of the Offered Warrants; (2) the designation and terms of any related Debt Securities with which the Offered Warrants are issued and the number of Offered Warrants issued with each such Debt Security; (3) the date, if any, on and after which the Offered Warrants and the related Offered Debt Securities will be separately transferable; (4) the principal amount of Debt Securities purchasable upon exercise of one Offered Warrant and the price at which such principal amount of Debt Securities may be purchased upon such exercise; (5) the date on which the right to exercise the Offered Warrants shall commence and the date (the "Expiration Date") on which such right shall expire; and (6) whether the Warrants represented by the Warrant Certificates will be issued in registered or bearer form, and if registered, where they may be transferred and registered. If the Debt Securities purchasable upon exercise of the Offered Warrants are issuable in bearer form, such Offered Warrants shall not be offered nor constitute an offer to, and Bearer Debt Securities issuable upon exercise of such Offered Warrants shall not be issued to, United States persons other than to offices outside the United States of certain United States financial institutions. See "Limitations on Issuance of Bearer Securities". Warrant Certificates will be exchangeable for new Warrant Certificates of different denominations and Warrants may be exercised at the corporate trust office of the Warrant Agent or any other office indicated in the Prospectus Supplement. Prior to the exercise of their Warrants, holders of Warrants will not have any of the rights of Holders of the Debt Securities purchasable upon such exercise and will not be entitled to payments of principal of (and premium, if any) or interest, if any, on the Debt Securities purchasable upon such exercise. DESCRIPTION OF PREFERRED STOCK The Company's Articles of Incorporation, as amended (the "Articles"), authorize the issuance of two classes of preferred stock, Serial Preferred Stock ("Class A Stock") and Class B Serial Preferred Stock ("Class B Stock"). As of the date of this Prospectus, there were 557,649 shares of Class A Stock outstanding. No additional shares of Class A Stock may be issued. The Company initiated an ongoing program to purchase and retire shares of Class A Stock in 1989. The following description of Class B Stock sets forth certain general terms and provisions of the series of Class B Stock to which any Prospectus Supplement may relate. The specific terms of a particular series of Class B Stock will be described in the Prospectus Supplement relating to such series of the Offered Preferred Stock (Offered Preferred Stock, Offered Debt Securities and Offered Warrants are collectively called "Offered Securities"). If so indicated in the Prospectus Supplement relating thereto, the terms of any such series of Class B Stock may differ from the terms set forth below. The description of Class B Stock set forth below and the description of the terms of a particular series of Class B Stock set forth in the Prospectus Supplement relating thereto do not purport to be complete and are qualified in their entirety by reference to the Company's Articles and the Statement with Respect to Shares relating to such series of Class B Stock, which will be filed or incorporated by reference as an exhibit to the Registration Statement of which this Prospectus is a part. 18

GENERAL The Company is authorized to issue 10,000,000 shares of Class B Stock. As of the date of this Prospectus, no shares of this class have been issued. The Board of Directors has the authority to issue Class B Stock in one or more series and to fix the specific number of shares, title, voting powers, if any, (except as otherwise required by law), liquidation preference of each share, issue price, dividend rate or rates (or method of calculation), dividend periods, dividend payment dates, any redemption or sinking fund provisions, and conversion provisions and any other specific terms of any series without any further action by shareholders of the Company unless action is required by applicable laws or regulations or by the terms of other outstanding preferred stock. The Prospectus Supplement will set forth the following specific terms regarding the series of Class B Stock offered thereby: (i) the designation, number of shares and liquidation preference per share; (ii) the initial public offering price; (iii) the dividend rate or rates, or the method of determining the dividend rate or rates; (iv) the index, if any, upon which the amount of dividends, if any, is determined; (v) the dates on which dividends, if any, will accrue and be payable, that such dividends will be cumulative, and the designated record dates for determining the holders entitled to such dividends; (vi) any redemption or sinking fund provisions; (vii) any conversion or exchange provisions; (viii) provisions for issuance of global securities;(ix) the currency (which may be composite currency) in which payment of dividends, if any, shall be payable if other than United States dollars; (x) voting rights, if any, (except as otherwise required by law); and (xi) any additional terms, preferences or rights and qualifications, limitations or restrictions thereof. The shares of Class B Stock will, when issued, be fully paid and nonassessable and will have no preemptive rights. The transfer agent, registrar, dividend disbursing agent and redemption agent for the Class B Stock will be specified in the Prospectus Supplement relating thereto. DIVIDENDS The holders of the Class B Stock of each series will be entitled to receive, when, as and if declared by the Board of Directors of the Company, out of funds legally available therefor, cumulative cash or other dividends at such rate or rates and on such dates as will be set forth in the Prospectus Supplement relating to such series. Such rates may be fixed or variable or both. If variable, the formula used for determining the dividend rate for each dividend period will be set forth in the Prospectus Supplement. Dividends will be payable to the holders of record as they appear on the stock books of the Company on such record dates as will be fixed by the Board of Directors of the Company and specified in the Prospectus Supplement. No dividends may be declared in respect of any dividend period on any series of Class B stock, unless all accrued dividends and the current quarterly dividend on Class A Stock shall have been paid in full or contemporaneously are declared and set apart. In the event that full cumulative dividends on shares of a series of Class B Stock have not been declared and paid or set apart when due, dividends thereon shall be declared and paid pro rata to the holders of such series entitled thereto. In the event that full cumulative dividends on any class or series of the Company's preferred stock (including dividends for the current quarter yearly dividend period for shares of Class A Stock) have not been declared and paid or set apart when due, the Company may not declare or pay any dividends on, or make other distributions on or make payment on account of the purchase, redemption, or other retirement, of its Common Stock. When dividends are not paid in full upon any series of Class B Stock, all dividends declared or made upon shares of Class B Stock shall be declared pro rata so that the amount of dividends declared per share on Class B Stock shall in all cases bear to each other the same ratio that accrued dividends per share on shares of each series of the Class B Stock. No interest shall be payable in respect of any dividend payment which may be in arrears. REDEMPTION The shares of any series of Class B Stock may be redeemable at the option of the Company, on the date or dates and at the redemption price or prices set forth in the Prospectus Supplement relating to such series. 19

If fewer than all shares of Class B Stock are to be redeemed, the shares to be redeemed shall be selected by the Company pro rata or by lot, or by any other method determined by the Board of Directors to be equitable. Notice of redemption shall be given by mailing (or by some other means deemed sufficient by the Board of Directors prior to issuance of each series of Class B Stock) the same to each record holder of the shares to be redeemed, not less than 30 nor more than 60 days prior to the date fixed for redemption thereof, to the respective addresses of such holders as the same shall appear on the Company's stock books. Each such notice shall state: (i) the redemption date; (ii) the number of shares and series of the Class B Stock to be redeemed; (iii) the redemption price and the manner in which such redemption price is to be paid and delivered; (iv) the place or places where certificates for such shares of Class B Stock are to be surrendered for payment of the redemption price; and (v) that dividends on the shares to be redeemed will cease to accrue on such redemption date. If fewer than all shares of any series of the Class B Stock held by any holder are to be redeemed, the notice mailed, or otherwise communicated, to such holder shall also specify the number of shares to be redeemed from such holder. If notice of redemption has been given, from and after the redemption date for the shares of the series of the Class B Stock called for redemption (unless default shall be made by the Company in providing money for the payment of the redemption price of the shares so called for redemption), dividends on the shares of Class B Stock so called for redemption will cease to accrue, any right to convert the shares of Class B Stock will terminate, such shares will no longer be deemed to be outstanding, and all rights of the holders thereof as shareholders of the Company (except the right to receive the redemption price) will cease. Upon surrender in accordance with such notice of the certificates representing any shares so redeemed (properly endorsed or assigned for transfer, if the Board of Directors of the Company; will so require and the notice shall so state), the redemption price referred to above will be paid out of funds provided by the Company. If fewer than all of the shares represented by any such certificate are redeemed, a new certificate will be issued representing the unredeemed shares without cost to the holder thereof. LIQUIDATION PREFERENCE Upon any liquidation, dissolution or winding up of the Company, the holders of Class A Stock shall be entitled to receive out of the assets of the Company available for distribution to shareholders before any distribution of assets is made to or set apart for the holders of Class B Stock. The holders of shares of each series of Class B Stock shall be entitled to receive out of the assets of the Company available for distribution to shareholders before any distribution of assets is made to or set apart for the holders of Common Stock, with respect to the Class B Stock, plus all dividends which have accrued on such series of Class B Stock and have not been paid or declared and a sum sufficient for payment thereof set apart, an amount described in the Prospectus Supplement relating to such series of Class B Stock. If, in any case of any such liquidation, dissolution or winding up of the Company, the assets of the Company or the proceeds thereof shall be insufficient to pay in full the amounts payable with respect to shares of each series of Class B Stock, the holders of shares of such series of Class B Stock will share ratably in any such distribution of assets of the Company in proportion to the full respective preferential amounts to which they are entitled. After payment to the holders of shares of such series of Class B Stock of the full preferential amounts to which they are entitled, the holders of shares of such series of Class B Stock will not be entitled to any further participation in any distribution of assets by the Company, unless otherwise provided in the Prospectus Supplement. A consolidation or merger of the Company with one or more corporations shall not be deemed to be a liquidation, dissolution or winding up of the Company. CONVERSION AND EXCHANGE RIGHTS The terms, if any, on which shares of any series of Class B Stock are convertible into or exchangeable for Common Stock will be set forth in the Prospectus Supplement relating thereto. Such terms may include provisions for conversion or exchange, either mandatory, at the option of the holder, or at the option of the Company, in which the number of shares of Common Stock to be received by the holders of Class B Stock would be calculated according to the market price of Common Stock as of a time stated in the Prospectus Supplement. 20

VOTING RIGHTS Except as indicated below or in the Prospectus Supplement relating to a particular series of the Class B Stock, or except as expressly required by applicable law, the holders of Class B Stock will not be entitled to vote. Pennsylvania law requires that holders of outstanding shares of a particular class or series be entitled to vote as a class on an amendment to the Articles that would (i) authorize the Board of Directors to fix and determine the relative rights and preferences as between series of any preferred stock or special class of stock; (ii) change the preferences, limitations or other special rights of the shares of a class or series adverse to that class or series; (iii) authorize a new class or series of shares having a preference as to dividends or assets which is senior to shares of a particular class or series; or (iv) increase the number of authorized shares of any particular class or series having a preference as to dividends or assets which is senior in any respect to the shares of such class or series. The Board of Directors, pursuant to the Company's Articles, may limit or eliminate the voting rights applicable to any series of Class B Stock prior to the issuance of such series, except as otherwise required by law. Any one or more series of the Class B Stock may be issued with such additional voting rights, exercisable only during certain extended periods of dividend arrearages, as the Board of Directors may determine to be required to qualify the series for listing on a recognized stock exchange. Such rights may only be granted if there are no shares of Class A Stock outstanding. On matters on which holders of such series and holders of any other series of Class B Stock are entitled to vote as a single class, each full share of any series of the Class B Stock shall be entitled to one vote. Therefore, the voting power of such series will depend on the number of shares in such series, not the liquidation preference or initial offering price of the shares of such series of the Class B Stock. So long as any shares of Class B Stock remain outstanding, the Company shall not, without the consent of the holders of at least two-thirds of the shares of the affected series of Class B Stock outstanding at the time (voting separately as a class with all other affected series of Class B Stock ranking on a parity with the affected series of Class B Stock), (i) authorize, create or issue, or increase the authorized amount of, any class or series of stock ranking prior to the affected series of Class B Stock as to dividends or upon liquidation; or (ii) amend, alter or repeal the provisions of the Company's Articles, whether by merger, consolidation or otherwise, so as to materially and adversely affect any right, preference, privilege or voting power of the affected series of Class B Stock or the holders thereof; provided, however, that any increase in the amount of the authorized Common Stock or authorized Class B Stock or the creation and issuance of other series of common stock or preferred stock ranking on a parity with or junior to the affected series of Class B Stock as to dividends and upon liquidation shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting powers. LIMITATIONS ON ISSUANCE OF BEARER SECURITIES In compliance with United States federal tax laws and regulations, Bearer Securities (including Securities in permanent global form) may not be offered, sold, resold or delivered during the restricted period (as defined in United States Treasury Regulations Section 1.163-5(c)(2)(i)(D)(7)) within the United States or to United States persons (each as defined below) other than to an office of a United States financial institution located outside the United States (as defined in Section 1.165-12(c)(1)(v) of the United States Treasury Regulations) purchasing for its own account or for resale or for the account of certain customers, that provides a certificate stating that it agrees to comply with the requirements of Section 165(j)(3)(A), (B) or (C) of the Code and the United States Treasury Regulations thereunder, or to certain other persons described in Section 1.163-5(c)(2)(i)(D)(1)(iii)(B) of the United States Treasury Regulations. Moreover, any distributor (as defined in Section 1.163- 5(c)(2)(i)(D)(4) of the United States Treasury Regulations) participating in the offering or sale of Bearer Securities must covenant that it will not offer or sell during the restricted period any Bearer Securities within the United States or to United States persons (other than the persons described above), it will not deliver in connection with the sale of Bearer Securities during the restricted period any Bearer Securities within the United States and it has in effect procedures reasonably designed to ensure that its employees and agents who are directly engaged in selling the Bearer Securities are aware of the restrictions 21

on offers and sales described above. No Bearer Security (other than a temporary global Security) may be delivered, nor may interest be paid on any Bearer Security (including a temporary global Security) until receipt by the Company, or its agent, of (i) a Depositary Tax Certification (as defined under "Description of Debt Securities--Temporary Global Securities") in the case of temporary global Securities or (ii) a certification in the form described under "Description of the Debt Securities--Form, Exchange, Registration and Transfer" in all other cases. Bearer Securities will bear a legend substantially to the following effect: "Any United States person who holds this obligation will be subject to limitations under the United States income tax laws, including the limitations provided in Sections 165(j) and 1287(a) of the Internal Revenue Code". Purchasers of Bearer Securities may be affected by certain limitations under United States tax laws. See "United States Taxation--Backup Withholding and Information Reporting". As used herein, "United States person" means a citizen or resident of the United States, a corporation, partnership or other entity created or organized in or under the laws of the United States and an estate or trust the income of which is subject to United States federal income taxation regardless of its source, and "United States" means the United States of America (including the States and the District of Columbia), its territories, its possessions and other areas subject to its jurisdiction. UNITED STATES TAXATION DEBT SECURITIES The following summary of the principal United States federal income tax consequences of the ownership of the Debt Securities is based on the opinion of Sullivan & Cromwell, special United States tax counsel to the Company. It deals only with Debt Securities held as capital assets by initial purchasers, and not with special classes of holders, such as dealers in securities or currencies, life insurance companies, persons holding Debt Securities as a hedge or hedged against currency risks or as part of a straddle, or persons whose functional currency is not the U.S. dollar. The discussion of original issue discount is based in part on regulations proposed, but not yet effective, under the Internal Revenue Code of 1986, as amended (the "Code") (the "Proposed Regulations"). While the Proposed Regulations are proposed to be effective for debt instruments issued sixty or more days after final regulations are issued, the Proposed Regulations are currently the best indication of the views of the Internal Revenue Service (the "Service") with respect to the federal income tax treatment of debt instruments having original issue discount. Prospective purchasers of Debt Securities should consult their own tax advisors concerning the extent to which the Proposed Regulations may be relied upon before they become effective and the general consequences, in their particular circumstances, under the Code and the laws of any other taxing jurisdiction of the ownership of Debt Securities. UNITED STATES HOLDERS Payments of Interest Interest on a Debt Security, whether payable in U.S. dollars or a currency, composite currency or basket of currencies other than U.S. dollars (a "Specified Currency"), other than interest on a Discount Debt Security (as defined below under "Original Issue Discount--General) that is not, under the Code, "fixed periodic interest" or, under the Proposed Regulations, "qualified stated interest" (each as defined below under "Original Issue Discount-- General"), will be taxable to a beneficial owner who or which is (i) a citizen or resident of the United States, (ii) a domestic corporation or (iii) otherwise subject to United States federal income taxation on a net income basis in respect of the Debt Security (a "United States Holder") as ordinary income at the time it is received or accrued, depending on the holder's method of accounting for tax purposes. If an interest payment is denominated in or determined by reference to a Specified Currency, the amount of income recognized by a cash basis United States Holder will be the U.S. dollar value of the interest payment, based on the exchange rate in effect on the date of receipt, regardless of whether the payment is in fact converted into U.S. dollars. Accrual basis United States Holders may determine the amount of income recognized with respect to such interest payments in accordance with either of two methods. 22

Under the first method, the amount of income recognized will be based on the average exchange rate in effect during the interest accrual period (or, with respect to an accrual period that spans two taxable years, the partial period within the taxable year). Upon receipt of an interest payment (including a payment attributable to accrued but unpaid interest upon the sale or retirement of a Debt Security) denominated in or determined by reference to a Specified Currency, an accrual basis United States Holder will recognize ordinary income or loss measured by the difference between such average exchange rate and the exchange rate in effect on the date of receipt, regardless of whether the payment is in fact converted into U.S. dollars. Under the second method, an accrual basis United States Holder may elect to translate interest income into U.S. dollars at the exchange rate in effect on the last day of the accrual period or, in the case of an accrual period that spans two taxable years, at the exchange rate in effect on the last day of the partial period within the taxable year. Additionally, if a payment of interest is actually received within 5 business days of the last day of the accrual period or taxable year, an electing accrual basis United States Holder may instead translate such accrued interest into U.S. dollars at the exchange rate in effect on the day of actual receipt. Any such election will apply to all debt instruments held by the United States Holder at the beginning of the first taxable year to which the election applies or thereafter acquired by the United States Holder, and will be irrevocable without the consent of the Service. ORIGINAL ISSUE DISCOUNT General. A Debt Security will be treated as issued at an original issue discount (a "Discount Debt Security") if the excess of the Debt Security's "stated redemption price at maturity" over its issue price equals or exceeds 1/4 of 1 percent of such Debt Security's stated redemption price at maturity multiplied by the number of complete years to its maturity. Generally, the issue price of a Debt Security will be the initial offering price to the public at which a substantial amount of the Debt Securities are sold. Under the Code, the "stated redemption price at maturity" of a Debt Security is the total of all payments provided by the Debt Security other than payments of interest based on a fixed rate payable at fixed periodic intervals of one year or less during the entire term of the Debt Security ("fixed periodic interest"). Under the Proposed Regulations, the "stated redemption price at maturity" of a Debt Security is the total of all payments provided by the Debt Security that are not payments of "qualified stated interest". Under the Proposed Regulations, a "qualified stated interest" payment is generally any one of a series of stated interest payments on a Debt Security that are unconditionally payable at least annually at a single fixed rate applied to the outstanding principal amount of the Debt Security and, for this purpose, interest is considered payable at a fixed rate only if the rate appropriately takes into account the length of the interval between stated interest payments. The Proposed Regulations provide special rules for Variable Rate Debt Securities (see "Original Issue Discount-- Variable Rate Debt Securities"). If the excess, if any, of a Debt Security's stated redemption price at maturity over its issue price is not sufficient, under the rules described above, to cause the Debt Security to be a Discount Debt Security, then such excess, if any, constitutes "de minimis original issue discount". Under the Proposed Regulations, unless the election described below under "Election to Treat All Interest as Original Issue Discount" is made, a United States Holder of a Debt Security with de minimis original issue discount must include such de minimis original issue discount in income as stated principal payments on the Debt Security are made. The includible amount with respect to each such payment will equal the product of the total amount of the Debt Security's de minimis original issue discount and a fraction, the numerator of which is the amount of the principal payment made and the denominator of which is the stated principal amount of the Debt Security. The Code provides rules that require United States Holders of Discount Debt Securities having a maturity of more than one year from their date of issue to include original issue discount in income before the receipt of cash attributable to such income. The amount of original issue discount includible in income by a United States Holder of a Discount Debt Security is the sum of the daily portions of original issue discount with respect to the Discount Debt Security for each day during the taxable year or portion of the taxable year in which the United States Holder holds such Discount Debt Security ("accrued original issue discount"). The daily portion is determined by allocating to each day in any "accrual period" a pro rata portion of the original issue discount allocable to that accrual period. Under the Code, until final or temporary regulations become effective, an accrual period is any six-month period (or shorter period from the issue date 23

of such Debt Security) which ends on a day in the calendar year corresponding to the maturity date of the Debt Security or the date six months before such date. The Proposed Regulations would allow the accrual periods with respect to a Debt Security to be any set of periods (which may be of varying lengths) selected by the United States Holder as long as (i) no accrual period is longer than one year and (ii) each scheduled payment of interest or principal on the Debt Security occurs at the end of an accrual period. The amount of original issue discount allocable to an accrual period equals the excess of (a) the product of the Discount Debt Security's adjusted issue price at the beginning of the accrual period and such Debt Security's yield to maturity (determined on the basis of compounding at the close of each accrual period and properly adjusted for the length of the accrual period) over (b) the sum of the payments of fixed periodic interest, if any, made on the Debt Security during (under the Proposed Regulations, of qualified stated interest on the Debt Security allocable to) the accrual period. Under the Code, the "adjusted issue price" of a Discount Debt Security at the beginning of an accrual period is the issue price of the Debt Security with the adjustments prescribed by the Code for all periods before the first day of such accrual period (e.g., increased by the amount of original issue discount allocable to prior accrual periods and decreased by the amount of all payments in prior accrual periods which were not fixed periodic interest payments). The Proposed Regulations provide that the "adjusted issue price" of a Discount Debt Security at the beginning of any accrual period is (x) the sum of the issue price of such Debt Security, the accrued original issue discount for each prior accrual period, and the amount of any qualified stated interest on such Debt Security that has accrued prior to the beginning of the accrual period but is not payable until a later date, less (y) any prior payments on the Debt Security that were not qualified stated interest payments and clarify that, for purposes of determining the amount of original issue discount allocable to an accrual period, if an interval between payments of qualified stated interest on the Debt Security contains more than one accrual period, then the amount of qualified stated interest payable at the end of such interval shall be allocated pro rata (on the basis of their relative lengths) between the accrual periods contained in the interval. The Code provides no specific guidance on the method to be used in determining the amount of original issue discount allocable to a short initial accrual period. The Proposed Regulations contain certain special rules that generally allow any reasonable method to be used in determining the amount of original issue discount allocable to a short initial accrual period (if all other accrual periods are of equal length) and require that the amount of original issue discount allocable to the final accrual period equal the excess of the amount payable at the maturity of the Debt Security (other than any payment of qualified stated interest) over the Debt Security's adjusted issue price as of the beginning of such accrual period. Under the Code and the Proposed Regulations, United States Holders of Discount Debt Securities generally will have to include in income increasingly greater amounts of original issue discount over the life of the Debt Securities. Acquisition Premium. Under the Proposed Regulations, a United States Holder that purchases a Debt Security as part of its original issuance for an amount in excess of its adjusted issue price (any such excess being "acquisition premium") and that does not make the election described below under "Election to Treat All Interest as Original Issue Discount" is permitted to reduce the daily portions of original issue discount by a fraction, the numerator of which is the excess of the United States Holder's adjusted basis in the Debt Security immediately after its purchase over the adjusted issue price of the Debt Security, and the denominator of which is the excess of the sum of all amounts payable on the Debt Security after the purchase date, other than payments of qualified stated interest, over the Debt Security's adjusted issue price. Market Discount. Under the Code, a Debt Security, other than a Debt Security that matures one year or less from the date of its original issuance, will be treated as purchased at a market discount (a "Market Discount Debt Security") if (i) the amount for which a United States Holder purchased the Debt Security is less than the Debt Security's issue price (as determined above under "Original Issue Discount--General") and (ii) the Debt Security's stated redemption price at maturity or, in the case of a Discount Debt Security, the Debt Security's "revised issue price," exceeds the amount for which the United States Holder purchased the Debt Security by at least 1/4 of 1 percent of such Debt Security's stated redemption price at maturity or revised issue price, respectively, multiplied by the number of complete years to the Debt Security's maturity. If the excess, if any, referred to in the preceding sentence is not sufficient to cause the Debt Security to be a 24

Market Discount Debt Security, then such excess constitutes "de minimis market discount". For these purposes, the revised issue price of a Debt Security equals its issue price, increased by the amount of any original issue discount that has accrued on the Debt Security. Any gain recognized on the maturity or disposition of a Market Discount Debt Security will be treated as ordinary income to the extent that such gain does not exceed the accrued market discount on the Debt Security. Alternatively, a United States Holder of a Market Discount Debt Security may elect to include market discount in income currently over the life of the Debt Security. Such an election shall apply to all debt instruments with market discount acquired by the electing United States Holder on or after the first day of the first taxable year to which the election applies. This election may not be revoked without the consent of the Service. Market discount on a Market Discount Debt Security will accrue on a straight- line basis unless the United States Holder elects to accrue the market discount on a constant yield to maturity basis. Such an election shall apply only to the Debt Security with respect to which it is made and may not be revoked without the consent of the Service. A United States Holder of a Market Discount Debt Security that does not elect to include market discount in income currently generally will be required to defer deductions for interest on borrowings allocable to such Debt Security in an amount not exceeding the accrued market discount on such Debt Security until the maturity or disposition of such Debt Security. Pre-Issuance Accrued Interest. The Proposed Regulations provide that if (i) a portion of the initial purchase price of a Debt Security is attributable to pre-issuance accrued interest, (ii) the first stated interest payment on the Debt Security is to be made within one year of the Debt Security's issue date and (iii) such payment will equal or exceed the amount of pre-issuance accrued interest, then a United States Holder may elect to decrease the issue price of the Debt Security by the amount of pre-issuance accrued interest, in which case a portion of the first stated interest payment will be treated as a return of the excluded pre-issuance accrued interest and not as an amount payable on the Debt Security. Optional Redemption. Under the Proposed Regulations, if the Company has an option to redeem a Debt Security, or the Holder has an option to cause a Debt Security to be repurchased, prior to the Debt Security's stated maturity, such option will be presumed to be exercised if, by utilizing any date on which the Debt Security may be redeemed or repurchased as the maturity date and the amount payable on such date in accordance with the terms of the Debt Security (the "redemption price") as the principal amount payable at maturity, the yield on the Debt Security would be (i) in the case of an option of the Company, lower than its yield to stated maturity or (ii) in the case of an option of the Holder, higher than its yield to stated maturity. If such option is not in fact exercised when presumed to be exercised, the Debt Security will be treated solely for original issue discount purposes as if it were redeemed or repurchased, and a new Debt Security were issued, on the presumed exercise date for an amount equal to the Debt Security's adjusted issue price on that date. Election to Treat All Interest as Original Issue Discount. Under the Proposed Regulations, an accrual basis United States Holder may elect to include in gross income all interest that accrues on a Debt Security using the constant yield method described above under the heading "Original Issue Discount-- General," with the modifications described below. For purposes of this election, interest includes stated interest, original issue discount, de minimis original issue discount, market discount, de minimis market discount and unstated interest, as adjusted by any amortizable bond premium (described below under "Debt Securities Purchased at a Premium") or acquisition premium. In applying the constant yield method to a Debt Security with respect to which this election has been made, the issue price of the Debt Security will equal the electing United States Holder's adjusted basis in the Debt Security immediately after its acquisition, the issue date of the Debt Security will be the date of its acquisition by the electing United States Holder, and no payments on the Debt Security will be treated as payments of qualified stated interest. This election will generally apply only to the Debt Security with respect to which it is made and may not be revoked without the consent of the Service. If this election is made with respect to a Debt Security with amortizable bond premium, then the electing United States Holder will be deemed to have elected to apply amortizable bond premium against interest with respect to all debt instruments with amortizable bond premium (other than debt instruments the interest on which is excludible 25

from gross income) held by such electing United States Holder as of the beginning of the taxable year in which the Debt Security with respect to which the election is made is acquired or thereafter acquired. The deemed election with respect to amortizable bond premium may not be revoked without the consent of the Service. If the election to apply the constant yield method to all interest on a Debt Security is made with respect to a Market Discount Debt Security, then the electing United States Holder will be treated as having made the election discussed above under "Original Issue Discount--Market Discount" to include market discount in income currently over the life of all debt instruments held or thereafter acquired by such United States Holder. Variable Rate Debt Securities. Under the Proposed Regulations, a Variable Rate Debt Security is a Debt Security which provides for total non-contingent payments which equal or exceed its issue price and stated interest, compounded or paid at least annually, at (w) a single qualified floating rate, (x) a qualified floating rate followed by another qualified floating rate, (y) a fixed rate followed by a qualified floating rate, or(z) a single objective rate, where any such qualified floating or objective rate in effect during an accrual period will be set at a current value of such rate. A floating rate is a "qualified floating rate" if variations in such rate can reasonably be expected to measure contemporaneous fluctuations in the cost of newly borrowed funds. An objective rate is a rate (other than a qualified floating rate) the formula for which is fixed throughout the term of the Debt Security and which is based on the price of actively traded property (other than nonfunctional currency), an index of the price of such property, or one or more qualified floating rates. Under these rules, Commercial Paper Rate Debt Securities, Prime Rate Debt Securities, LIBOR Debt Securities, Treasury Rate Debt Securities, CD Rate Debt Securities, and Federal Funds Debt Securities, other than certain Debt Securities subject to interest rate caps or floors, should generally be treated as Variable Rate Debt Securities. Under the Proposed Regulations, stated interest on a Variable Rate Debt Security is qualified stated interest if such interest is unconditionally payable at least annually. Where a Variable Rate Debt Security provides for a fixed rate followed by a floating rate or a floating rate followed by another floating rate and the fair market value of the Debt Security would not be approximately equal to its current fair market value if the latter rate were in effect throughout the term of the Debt Security, then some portion of the interest on the Debt Security will be treated as either accelerated or deferred interest and such accelerated or deferred interest will not be treated as qualified stated interest. If the substitution described in the preceding sentence would decrease the fair market value of the Debt Security, then the interest for the initial interval (the interval in which the initial rate is in effect) that is attributable to the portion of the stated interest for such interval that is in excess of the hypothetical initial rate that would make the substitution have approximately no effect on the fair market value of the Debt Security will be accelerated interest. If the substitution would increase the fair market value of the Debt Security, then the interest for the later interval that is attributable to the portion of the stated interest for such interval that is in excess of the hypothetical latter rate that would make the substitution have approximately no effect on the fair market value of the Debt Security is deferred interest. Under the Proposed Regulations, the original issue discount for an accrual period on a Variable Rate Debt Security that arises from stated interest that is not unconditionally payable at least annually (other than accelerated or deferred interest) is the amount of stated interest that actually accrues under the terms of the Debt Security during the accrual period. The original issue discount on a Variable Rate Debt Security that arises from (i) an excess of the Debt Security's stated principal amount over its issue price, (ii) accelerated interest, or (iii) deferred interest must be allocated to an accrual period in accordance with a reasonable application of the constant yield method described above under "Original Issue Discount--General." The Code delegates to the Treasury Department the authority to prescribe special rules relating to the tax treatment, under the original issue discount provisions of the Code, of Debt Securities that satisfy the definition of Variable Rate Debt Securities. Because the Proposed Regulations are not yet effective, United States Holders should discuss with their tax advisors the treatment of such Debt Securities under the Code and, if applicable, the proposed regulations that describe the application of the original issue discount provisions of the Code to debt instruments with contingent payments. 26

Short-Term Debt Securities. Under the Code, special rules apply with respect to original issue discount on a Debt Security that matures one year or less from the date of its original issuance (a "short-term Debt Security"). In general, an individual or other cash basis United States Holder of a short-term Debt Security is not required to accrue original issue discount for United States federal income tax purposes unless it elects to do so. Accrual basis United States Holders and certain other United States Holders, including banks, regulated investment companies, dealers in securities and cash basis United States Holders who so elect, are required to accrue original issue discount on short-term Debt Securities on either a straight-line basis or under the constant yield method (based on daily compounding), at the election of the United States Holder. In the case of a United States Holder not required and not electing to include original issue discount in income currently, any gain realized on the sale or retirement of the short-term Debt Security will be ordinary income to the extent of the original issue discount accrued on a straight-line basis (unless an election is made to accrue the original issue discount under the constant yield method) through the date of sale or retirement. United States Holders who are not required and do not elect to accrue original issue discount on short-term Debt Securities will be required to defer deductions for interest on borrowings allocable to short-term Debt Securities in an amount not exceeding the deferred income until the deferred income is realized. For purposes of determining the amount of original issue discount subject to these rules, the Proposed Regulations provide that all interest payments on a short-term Debt Security, including qualified stated interest, are included in the short-term Debt Security's stated redemption price at maturity. Foreign Currency Discount Debt Securities. Original issue discount for any accrual period on a Discount Debt Security that is denominated in a Specified Currency will be determined in the Specified Currency and then translated into U.S. dollars in the same manner as stated interest accrued by an accrual basis United States Holder, as described under "United States Holders--Payments of Interest." Upon receipt of an amount attributable to original issue discount (whether in connection with a payment of interest or the sale or retirement of a Debt Security), a United States Holder may recognize ordinary income or loss. DEBT SECURITIES PURCHASED AT A PREMIUM Under the Code, a United States Holder that purchases a Debt Security for an amount in excess of its principal amount may elect to treat such excess as "amortizable bond premium", in which case the amount required to be included in the United States Holder's income each year with respect to interest on the Debt Security will be reduced by the amount of amortizable bond premium allocable (based on the Debt Security's yield to maturity) to such year. In the case of a Debt Security that is denominated in a Specified Currency, bond premium will be computed in units of Specified Currency, and amortizable bond premium will reduce interest income in units of the Specified Currency. At the time amortized bond premium offsets interest income, exchange gain or loss (taxable as ordinary income or loss, but generally not as interest income or expense) is realized measured by the difference between exchange rates at that time and at the time of the acquisition of the Debt Securities. Any election to amortize bond premium shall apply to all bonds (other than bonds the interest on which is excludible from gross income) held by the United States Holder at the beginning of the first taxable year to which the election applies or thereafter acquired by the United States Holder, and is irrevocable without the consent of the Service. See also "Original Issue Discount--Election to Treat All Interest as Original Issue Discount". PURCHASE, SALE AND RETIREMENT OF THE DEBT SECURITIES A United States Holder's tax basis in a Debt Security will generally be its U.S. dollar cost (which, in the case of a Debt Security purchased with a Specified Currency, will be the U.S. dollar value of the purchase price on the date of purchase), increased by the amount of any original issue discount or market discount included in the United States Holder's income with respect to the Debt Security and, under the Proposed Regulations, the amount, if any, of income attributable to de minimis original issue discount included in the United States Holder's income with respect to the Debt Security, and reduced by (i) under the Code, the amount of any payments other than payments of fixed periodic interest or, under the Proposed Regulations, the amount of any payments that are not qualified stated interest payments, and (ii) the amount of any amortizable bond premium applied to reduce interest on the Debt Security. A United States Holder will generally recognize gain or loss on the sale or retirement of a Debt Security equal to the difference between 27

the amount realized on the sale or retirement and the tax basis of the Debt Security. The amount realized on a sale or retirement for an amount in Specified Currency will be the U.S. dollar value of such amount on the date of sale or retirement. Except to the extent described above under "Original Issue Discount--Short-Term Debt Securities" or "Original Issue Discount--Market Discount", described in the next succeeding paragraph or attributable to accrued but unpaid interest, gain or loss recognized on the sale or retirement of a Debt Security will be capital gain or loss and will be long-term capital gain or loss if the Debt Security was held for more than one year. Gain or loss recognized by a United States Holder on the sale or retirement of a Debt Security that is attributable to changes in exchange rates will be treated as ordinary income or loss. However, exchange gain or loss is taken into account only to the extent of total gain or loss realized on the transaction. EXCHANGE OF AMOUNTS IN OTHER THAN U.S. DOLLARS Specified Currency received as interest on a Debt Security or on the sale or retirement of a Debt Security will have a tax basis equal to its U.S. dollar value at the time such interest is received or at the time of such sale or retirement. Specified Currency that is purchased will generally have a tax basis equal to the U.S. dollar value of the Specified Currency on the date of purchase. Any gain or loss recognized on a sale or other disposition of a Specified Currency (including its use to purchase Debt Securities or upon exchange for U.S. dollars) will be ordinary income or loss. INDEXED DEBT SECURITIES The applicable Prospectus Supplement will contain a discussion of any special United States federal income tax rules with respect to Debt Securities payments on which are determined by reference to any index. CONVERTIBLE DEBT SECURITIES The applicable Prospectus Supplement will contain a discussion of any special United States federal income tax consequences of holding Debt Securities that are convertible into or exchangeable for Common Stock. UNITED STATES ALIEN HOLDERS For purposes of this discussion, a "United States Alien Holder" is any holder who or which is (i) a nonresident alien individual, (ii) a foreign corporation, partnership or estate or trust, in either case not subject to United States federal income tax on a net income basis in respect of a Debt Security. Under present United States federal income and estate tax law and subject to the discussion of backup withholding below: (i) if the Debt Securities are offered, sold and delivered, and principal and interest thereon are paid in accordance with the terms of the Indenture and the applicable Underwriting Agreement, payments of principal, premium (if any) and interest (including original issue discount) by the Company or any of its paying agents to any holder of a Debt Security or coupon who or which is a United States Alien Holder will not be subject to United States federal withholding tax; provided, that in the case of interest or original issue discount, (a) the beneficial owner of the Debt Security does not actually or constructively own 10% or more of the total combined voting power of all classes of stock of the Company entitled to vote, (b) the beneficial owner of the Debt Security is not a controlled foreign corporation that is related to the Company through stock ownership, and (c) if the Debt Security is a Registered Security (as defined in the Indenture including such debt securities that were received in exchange for Bearer Securities), either (A) the beneficial owner of the Debt Security certifies to the Company or its agent, under penalties of perjury, that it is not a United States Holder and provides its name and address or (B) a securities clearing organization, bank or other financial institution that holds customers' securities in the ordinary course of its trade or business (a "financial institution") and holds the Debt Security certifies to the Company or its agent under penalties of perjury that such statement has been received from the beneficial owner by it or by a financial institution between it and the beneficial owner and furnishes the payor with a copy thereof; 28

(ii) a United States Alien Holder of a Debt Security will not be subject to United States federal withholding tax on any gain realized on the sale or exchange of a Debt Security; and (iii) a Debt Security or coupon held by an individual who at the time of death is not a citizen or resident of the United States will not be subject to United States federal estate tax as a result of such individual's death if the individual does not actually or constructively own 10% or more of the total combined voting power of all classes of stock of the Company entitled to vote and the income on the Debt Security would not have been effectively connected with a U.S. trade or business of the individual. BACKUP WITHHOLDING AND INFORMATION REPORTING United States Holders In general, information reporting requirements will apply to payments of principal, and any premium and interest made on a Debt Security and the proceeds of the sale of a Debt Security before maturity within the United States to, and to the accrual of original issue discount on a Discount Debt Security with respect to, non-corporate United States Holders, and "backup withholding" at a rate of 31% will apply to such payments and to payments of original issue discount if the United States Holder fails to provide an accurate taxpayer identification number or to report all interest and dividends required to be shown on its federal income tax returns. United States Alien Holders Information reporting and backup withholding will not apply to payments of principal, premium (if any) and interest (including original issue discount) made by the Company or a paying agent (i) outside the United States on Bearer Securities, or (ii) on any Debt Security if the certification described in clause (i)(c) under "United States Alien Holders" above is received, provided, in either case, that the payor does not have actual knowledge that the holder is a United States person. Payments of the proceeds from the sale by a United States Alien Holder of a Debt Security made to or through a foreign office of a broker will not be subject to information reporting or backup withholding, except that if the broker is a United States person, a controlled foreign corporation for United States tax purposes or a foreign person 50% or more of whose gross income is effectively connected with a United States trade or business for a specified three-year period, information reporting may apply to such payments. Payments of the proceeds from the sale of a Debt Security to or through the United States office of a broker is subject to information reporting and backup withholding unless the holder or beneficial owner certifies as to its non- United States status or otherwise establishes an exemption from information reporting and backup withholding. WARRANTS The applicable Prospectus Supplement will contain a discussion of the United States federal income tax consequences of holding Warrants. PREFERRED STOCK The applicable Prospectus Supplement will contain a discussion of the United States federal income tax consequences of holding Preferred Stock, including Preferred Stock that is convertible into or exchangeable for Common Stock. PLAN OF DISTRIBUTION The Company may sell Offered Securities to one or more underwriters for public offering and sale by them or may sell Securities to investors directly or through agents. Any such underwriter or agent involved in the offer and sale of the Offered Securities will be named in an applicable Prospectus Supplement. Underwriters may offer and sell the Offered Securities at a fixed price or prices, which may be changed, or from time to time at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. The Company also may, from time to time, authorize underwriters acting as the Company's agents to offer and sell the Offered Securities upon the terms and conditions as shall be set 29

forth in any Prospectus Supplement. In connection with the sale of Offered Securities, underwriters may be deemed to have received compensation from the Company in the form of underwriting discounts or commissions and may also receive commissions from purchasers of Offered Securities for whom they may act as agent. Underwriters may sell Offered Securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions (which may be changed from time to time) from the purchasers for whom they may act as agent. Any underwriting compensation paid by the Company to underwriters or agents in connection with the offering of Offered Securities, and any discounts, concessions or commissions allowed by underwriters to participating dealers, will be set forth in an applicable Prospectus Supplement. Underwriters, dealers and agents participating in the distribution of the Offered Securities may be deemed to be underwriters, and any discounts and commissions received by them and any profit realized by them on resale of the Offered Securities may be deemed to be underwriting discounts and commissions under the Act, as amended. Underwriters, dealers and agents may be entitled, under agreements with the Company, to indemnification against and contribution toward certain civil liabilities, including liabilities under the Act, and to reimbursement by the Company for certain expenses. If so indicated in an applicable Prospectus Supplement, the Company will authorize dealers acting as the Company's agents to solicit offers by certain institutions to purchase Offered Securities from the Company at the public offering price set forth in such Prospectus Supplement pursuant to Delayed Delivery Contracts ("Contracts") providing for payment and delivery on the date or dates stated in such Prospectus Supplement. Each Contract will be for an amount not less than, and the aggregate amount of Offered Securities sold pursuant to Contracts shall be not less nor more than, the respective amounts stated in such Prospectus Supplement. Institutions with whom Contracts, when authorized, may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but will in all cases be subject to the approval of the Company. Contracts will not be subject to any conditions except (i) the purchase by an institution of the Offered Securities covered by its Contracts shall not at the time of delivery be prohibited under the laws of any jurisdiction in the United States to which such institution is subject, and (ii) if the Offered Securities are being sold to underwriters, the Company shall have sold to such underwriters the total principal amount of the Offered Securities less the principal amount thereof covered by Contracts. Agents and underwriters will have no responsibility in respect of the delivery or performance of Contracts. Each underwriter, dealer and agent participating in the distribution of any Offered Securities which are issuable in bearer form will agree that it will not offer, sell or deliver, directly or indirectly, Offered Securities in bearer form in the United States or to United States persons (other than qualifying financial institutions) during the restricted period (as defined in United States Treasury Regulations Section 1.163-5(c)(2)(i)(D)(7)). See "Limitations on Issuance of Bearer Securities". The Securities may not be offered or sold directly or indirectly in Great Britain other than to persons whose ordinary business it is to buy or sell shares or debentures (except in circumstances which do not constitute an offer to the public within the meaning of the Companies Act 1985), and this Prospectus and any Prospectus Supplement or any other offering material relating to the Securities may not be distributed in or from Great Britain other than to persons whose business involves the acquisition and disposal, or the holding, of securities whether as principal or as agent. All Offered Securities will be a new issue of securities with no established trading market. Any underwriters to whom Offered Securities are sold by the Company for public offering and sale may make a market in such Offered Securities, but such underwriters will not be obligated to do so and may discontinue any market making at any time without notice. No assurance can be given as to the liquidity of the secondary market for any Offered Securities. Certain of the underwriters or agents and their associates may be customers of, engage in transactions with and perform services for the Company in the ordinary course of business. 30

VALIDITY OF OFFERED SECURITIES The validity of the Offered Securities will be passed upon for the Company by Denis A. Demblowski, Esq., Managing General Attorney of the Company, and for any underwriters or agents by Sullivan & Cromwell, New York, New York. Sullivan & Cromwell will rely, as to all matters governed by Pennsylvania law, on the opinion of Denis A. Demblowski, Esq. Mr. Demblowski is a participant in the stock option plan and various other employee benefit plans offered to employees of the Company. Sullivan & Cromwell also may act as special tax counsel to the Company in connection with the Offered Securities. INDEPENDENT PUBLIC ACCOUNTANTS The consolidated financial statements and related schedules in the Company's Annual Report on Form 10-K for the year ended December 31, 1992, incorporated by reference in this Prospectus, have been incorporated herein by reference in reliance upon the reports of Coopers & Lybrand given upon their authority as experts in auditing and accounting. With respect to the unaudited financial information for the periods ended March 31, June 30 and September 30, 1993 and 1992, incorporated by reference in this Prospectus, the independent accountants have reported that they have applied limited procedures in accordance with professional standards for a review of such information. However, their separate report included in the Company's quarterly reports on Form 10-Q for the quarters ended March 31, 1993, June 30, 1993 and September 30, 1993, and incorporated by reference herein, states that they did not audit and they do not express an opinion on that interim financial information. Accordingly, the degree of reliance on their report on such information should be restricted in light of the limited nature of the review procedures applied. The accountants are not subject to the liability provisions of Section 11 of the Act for their report on the unaudited interim financial information because that report is not a "report" or a "part" of the registration statement prepared or certified by the accountants within the meaning of Sections 7 and 11 of the Act. 31
