To: Continental Stock Transfer & Trust Company 2 Broadway New York, New York 10004 Ladies and Gentlemen: The undersigned hereby surrenders the Certificates listed in Box A above (or guarantees delivery of such Certificates or the Shares covered hereby in accordance with a Guarantee of Delivery), and makes the Election set forth in Box C below, or, if an Election is not duly made, elects to have the undersigned's Shares treated as Undesignated Shares. The undersigned understands that the purposes of the election procedures described herein are to permit holders of Shares to express their preferences for the type of consideration they wish to receive in the Merger, and further understands that no less than 60% and no more than 80% of the issued and outstanding Shares of CU Stock may be exchanged for shares of PCFC Stock in the Merger. In addition, the Election by each holder of CU Stock, including this Election by the undersigned, will be subject to the results of the election and proration procedures set forth in the Merger Agreement and summarized in the Proxy Statement/Prospectus under the caption "THE MERGER--Consideration Payable Upon Consummation of the Merger". Accordingly, there can be no assurance that the undersigned holder will receive the proportion of PCFC Stock and/or cash indicated by such holder's Election. Receipt of the Proxy Statement/Prospectus, including the Merger Agreement attached as Appendix A thereto, is hereby acknowledged. In connection with the Merger, subject to the election and proration procedures set forth in the Merger Agreement, each holder of CU Stock is entitled, with respect to the Merger Consideration to be received for such holder's Shares of CU Stock, to (i) elect to receive for every such Share a fraction of a share of PCFC Stock equal to the Exchange Ratio (as defined below) (a "Stock Election"), (ii) elect to receive for every such Share cash in the amount of $15.34, or (iii) elect to receive a combination of shares of PCFC Stock (at the rate of the Exchange Ratio for a whole share of CU Stock) for a specified number of such holder's Shares and cash (at the rate of $15.34 for a whole share of CU Stock) for a specified number of such holder's Shares (a "Combination Election"). If a holder does not make an Election, his or her Shares will be deemed "Undesignated Shares" (as defined in the Merger Agreement). The "Exchange Ratio" is the quotient obtained by dividing (A) $15.34 by (B) the average of the daily closing prices of a share of PCFC Stock on the New York Stock Exchange as reported in The Wall Street Journal for the twenty consecutive trading days ending on the third trading day immediately prior to the Closing Date (as defined in the Merger Agreement) (the "Average Price of PCFC Stock"), provided however, that (i) if the Average Price of PCFC Stock is more than $51.03125, the Exchange Ratio will be fixed at .3006; and (ii) if the Average Price of PCFC Stock is less than $37.71875, the Exchange Ratio will be fixed at .4067. If (as currently anticipated) the Closing Date is July 3, 1997, the Exchange Ratio will not be determinable prior to the date of the Election Deadline. Notwithstanding the foregoing, the holder of Shares exchanged pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of PCFC Stock will receive cash (without interest) in an amount equal to such fractional part of a share of PCFC Stock multiplied by the Average Price of PCFC Stock. Neither the PCFC Board of Directors nor the CU Board of Directors makes any recommendation as to the type of consideration shareholders should elect to receive. Each shareholder must make his or her own decision with respect to such Election. By completing Box C below, each CU shareholder may choose to make a Cash Election, a Stock Election, a Combination Election, or no election with respect to the Shares held by such holder. BOX C
ELECTION (Check only one box) The undersigned, subject to the terms and conditions set forth in this Letter of Transmittal, including the Merger Agreement incorporated herein by reference, makes the following Election with respect to the undersigned's Shares covered hereby: / / A Cash Election with respect to ALL of such Shares. / / A Stock Election with respect to ALL of such Shares. / / A Combination Election, in which the following numbers of such Shares will be converted into cash and PCFC Stock, respectively: COMBINATION ELECTION (FILL IN NUMBERS OF SHARES TO BE SO CONVERTED) CASH STOCK TOTAL (NO.

Signature ------------------------------------ Date --------------, 1997 INSTRUCTIONS TO LETTER OF TRANSMITTAL A. LETTER OF TRANSMITTAL 1. DELIVERY OF LETTER OF TRANSMITTAL AND CERTIFICATES. This Letter of Transmittal is to be used if Certificates are forwarded herewith or if delivery of the CU Stock covered hereby is guaranteed in accordance with the terms hereof. Certificates evidencing all CU Stock covered hereby (or a Guarantee of Delivery as provided herein), together with a properly completed and duly executed Letter of Transmittal (or manually signed facsimile thereof), with any required signature guarantees, and any other documents required by this Letter of Transmittal, must be received by the Exchange Agent at its address set forth in the Letter of Transmittal prior to the Election Deadline. THE SHARES OF CU SHAREHOLDERS WHOSE LETTERS OF TRANSMITTAL AND ALL REQUIRED DOCUMENTS ARE NOT RECEIVED PRIOR TO THE ELECTION DEADLINE WILL BE TREATED AS UNDESIGNATED SHARES (AS DEFINED IN THE MERGER AGREEMENT). These instructions need not be returned. 2. GUARANTEE OF DELIVERY. In lieu of forwarding Certificates, shareholders may deliver their Certificates pursuant to the guaranteed delivery procedure contained herein. The Exchange Agent is also authorized to accept, on such conditions as the Exchange Agent determines, book-entry transfers of Shares covered by a Guarantee of Delivery, without tender of Certificates therefor. Pursuant to the guaranteed delivery procedure: (i) a properly completed and duly executed Letter of Transmittal with any required signature guarantees and with Box B entitled "Guarantee of Delivery" properly completed and duly executed, and any other documents required by this Letter of Transmittal, must be received by the Exchange Agent prior to the Election Deadline; and (ii) the Certificates in proper form for transfer (or a confirmation of book-entry transfer of the Shares to the Exchange Agent's account), must be received by the Exchange Agent no later than 5:00 p.m. Eastern Daylight Time on the third New York Stock Exchange trading day after the date of execution of the Guarantee of Delivery. If the guarantor fails to deliver on a timely basis the Certificates (or the Shares pursuant to a book-entry transfer) in accordance with applicable guaranteed delivery procedures, any purported Election with respect to Certificates or Shares subject to such guarantee will be void. 3. SHARES HELD BY NOMINEES, TRUSTEES OR OTHER REPRESENTATIVES. Any record holder of CU Stock who holds such CU Stock as a nominee, trustee or in another representative or fiduciary capacity (a "nominee") may submit one or more Letters of Transmittal covering the aggregate number of shares of CU Stock held by such nominee for the beneficial owners for whom the nominee is making an Election; provided, that each submission of a Letter of Transmittal by a nominee shall be deemed to constitute a certification by such nominee that such Letter of Transmittal covers all of the CU Stock held by such nominee for a particular beneficial owner. If Certificates are forwarded to the Exchange Agent in multiple deliveries, a properly completed and duly executed Letter of Transmittal must accompany each such delivery. Any nominee who submits a Letter of Transmittal may be required to provide the Exchange Agent with such documents and/or certifications (in addition to any evidence of authority required by Instruction A5) as may be requested in order to satisfy the Exchange Agent that such nominee holds for a particular beneficial owner the CU Stock covered thereby. If any Shares of CU Stock held by a nominee are not covered by an effective Election, they will be deemed to be Undesignated Shares. 4. METHOD OF DELIVERY. THE METHOD OF DELIVERY OF THIS LETTER OF TRANSMITTAL, CERTIFICATES, AND ALL OTHER REQUIRED DOCUMENTS IS AT THE OPTION AND RISK OF THE SENDER, AND THE DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY RECEIVED BY THE EXCHANGE AGENT. The risk of loss of such Certificate(s) shall pass only after the Exchange Agent has actually received the Certificate(s). If delivery is by mail, registered mail with return receipt requested, properly insured, is recommended. In all cases, sufficient time should be allowed to ensure timely delivery by the Election Deadline. 5. SIGNATURES ON LETTER OF TRANSMITTAL; STOCK POWERS AND CERTIFICATE ENDORSEMENTS. If this Letter of Transmittal is signed by the registered holder(s) of the Shares covered hereby, the signature(s) must correspond with the name(s) on the face of the Certificates evidencing such Shares without alteration, enlargement, or any other change whatsoever. If any of the Shares covered hereby are owned of record by two or more persons, all such persons must sign this Letter of Transmittal. If any Certificates delivered herewith are registered in the names of different holders, it will be necessary to complete, sign, and submit as many separate Letters of Transmittal as there are different registrations of such Certificates. If this Letter of Transmittal is signed by the registered holder(s) of the Shares covered hereby, no endorsements of Certificates or separate stock powers are required, unless checks or certificates evidencing shares of PCFC Stock are to be payable to the order of, or registered in the name of, a person other than the registered holder(s) of such Shares, in which case Box D must be completed and the Certificate(s) evidencing the Shares must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name(s) of the registered holder(s) appear(s) on such Certificate(s). Signatures on such Certificate(s) and stock powers must be guaranteed by an Eligible Institution (as defined in Instruction A6). If this Letter of Transmittal is signed by a person other than the registered holder(s) of the Shares covered hereby, the Certificate(s) evidencing such Shares must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name(s) of the registered holder(s) appear(s) on such Certificate(s). Signatures on such Certificate(s) and stock powers must be guaranteed by an Eligible Institution. IF THIS LETTER OF TRANSMITTAL OR ANY CERTIFICATE OR STOCK POWER IS SIGNED BY A TRUSTEE, EXECUTOR, ADMINISTRATOR, GUARDIAN, ATTORNEY-IN-FACT, OFFICER OF A CORPORATION, OR OTHER PERSON ACTING IN A FIDUCIARY OR REPRESENTATIVE CAPACITY, SUCH PERSON SHOULD SO INDICATE WHEN SIGNING, AND PROPER EVIDENCE SATISFACTORY TO THE EXCHANGE AGENT OF SUCH PERSON'S AUTHORITY TO SO ACT MUST BE SUBMITTED. 6. GUARANTEE OF SIGNATURES. Except as otherwise provided below, all signatures on this Letter of Transmittal must be guaranteed by a bank, broker, dealer, credit union, savings association, or other entity that is a member in good standing of the Securities Transfer Association's Medallion Program (each, an "Eligible Institution"). No signature guarantee is required on this Letter of Transmittal if this Letter of Transmittal is signed by the registered holder(s) of Certificates covered hereby, unless such holder(s) has completed either the box entitled "Special Delivery Instructions" or the box entitled "Special Payment Instructions." In addition, if a Certificate is registered in the name of a person other than the signer of this Letter of Transmittal, or if checks or certificates are to be payable to the order of or registered in the name of a person other than the registered holder(s), then the Certificate must be endorsed or accompanied by appropriate stock powers, in either case signed exactly as the name(s) of the registered holder(s) appear(s) on the Certificate, with the signature(s) on such Certificate or stock powers guaranteed by an Eligible Institution. 7. DETERMINATION OF PROPER ELECTION. The Exchange Agent will have the reasonable discretion to determine whether Letters of Transmittal have been properly or timely completed, signed, and submitted, modified or revoked, and to disregard immaterial defects in Letters of Transmittal. In all such matters, the decision of the Exchange Agent, and any decision of PCFC and CU required by the Exchange Agent and made in good faith, shall be conclusive and binding. The Exchange Agent will not be under any obligation to notify any person of any defect in a Letter of Transmittal or other documents submitted to the Exchange Agent. The Exchange Agent shall make all proration computations contemplated by the Merger Agreement (other than computation of the Exchange Ratio, which shall be made by PCFC) and all such computations shall be conclusive and binding on the holders of CU Stock. No alternative, conditional, or contingent Elections will be accepted. If the Exchange Agent shall reasonably determine that any purported Stock Election, Cash Election or Combination Election was not properly made, such purported Stock Election, Cash Election or Combination Election will be of no force and effect and the shareholder making such purported Stock Election, Cash Election or Combination Election shall, for purposes hereof and the Merger Agreement, be deemed not to have made an Election and the Shares covered thereby shall be deemed to be Undesignated Shares. 8. INADEQUATE SPACE. If the space provided in Box A under "Description of Shares" is inadequate, the Certificate numbers, the number of Shares evidenced by such Certificates, and the number of Shares with respect to which Elections are made should be listed on a separate schedule and attached to the Letter of Transmittal. 9. TERMINATION OF MERGER AGREEMENT. All Elections will be revoked automatically if the Exchange Agent is notified in writing by PCFC or CU that the Merger Agreement has been terminated, and Certificates will be promptly returned to the persons who have submitted them by registered mail (with attendant delay). 10. DISSENTERS' RIGHTS. Holders of CU Stock who wish to exercise dissenters' rights should not complete this Letter of Transmittal. PCFC will regard any record holder of CU Stock who has delivered a written demand for dissenters' rights and who subsequently delivers a Letter of Transmittal to the Exchange Agent as having withdrawn such demand for dissenters' rights. PCFC will regard any holder who has delivered a Letter of Transmittal and who simultaneously or subsequently makes a written demand for dissenters' rights as having revoked his or her Election. For information concerning dissenters' rights, see the information set forth in Appendix C of the Proxy Statement/ Prospectus and the summary set forth therein under the caption "DISSENTERS' RIGHTS." B. ELECTION PROCEDURES 1. ELECTIONS. By completing Box C entitled "Election" and this Letter of Transmittal, and making the deliveries required hereby, each in accordance with these instructions, a CU shareholder will be permitted to make a Stock Election, Cash Election or Combination Election with respect to the Shares held by such holder. All Elections are subject to the election and proration procedures set forth in Section 2.3 of the Merger Agreement. In connection with making any Election, a CU shareholder should also carefully read, among other items, the information contained in the Proxy Statement/Prospectus under "THE MERGER--Certain Federal Income Tax Considerations." Each CU shareholder should consult his or her own tax advisor as to the specific tax consequences of an Election and the Merger to such shareholder. 2. TREATMENT OF NON-ELECTING SHARES. Any Shares (other than Dissenting Shares) with respect to which the Exchange Agent does not receive an effective, properly completed Letter of Transmittal prior to the Election Deadline will be deemed to be Undesignated Shares. This Letter of Transmittal will be deemed properly completed only if: (i) an Election is indicated for each Share covered by this Letter of Transmittal, (ii) accompanied by one or more Certificates with respect to such Shares (or (a) such documents concerning lost certificates as are required pursuant to Instruction C4, or (b) a properly executed Guarantee of Delivery with respect to such Shares), and (iii) accompanied by any other documents required by the Exchange Agent or PCFC. 3. ELECTION DEADLINE. In order for an Election to be effective, the Exchange Agent must receive a properly completed Letter of Transmittal, accompanied by all required documents, no later than 5:00 p.m., Eastern Daylight Time, on June 30, 1997, unless extended to a later date by the mutual agreement of CU and PCFC (the "Election Deadline"). 4. CHANGES TO ELECTIONS. Any holder of CU Stock who has made an Election may, at any time prior to the Election Deadline, change his or her Election by submitting to the Exchange Agent a properly completed and signed revised Letter of Transmittal with all required additional documents, provided that the Exchange Agent receives such revised Letter of Transmittal and other necessary documents prior to the Election Deadline. Any holder of CU Stock may at any time prior to the Election Deadline revoke his or her Election and withdraw his or her Certificates deposited with the Exchange Agent by written notice to the Exchange Agent received prior to the Election Deadline. If an Election is revoked prior to the Election Deadline, the related CU Stock will automatically become Undesignated Shares unless and until a new Election is properly made with respect to such CU Stock on or before the Election Deadline. In such event, upon request of the holder who submitted the revoked Election, Certificates representing the related CU Stock will be returned without charge to such holder. 5. NO FRACTIONAL SHARES. No certificates representing fractional shares of PCFC Stock will be issued in the Merger. In lieu of any fractional share of PCFC Stock, holders of Shares that are converted into the right to receive PCFC Stock will receive cash (without interest) in an amount equal to such fractional share of PCFC Stock multiplied by the Average Price of PCFC Stock. 6. UNDESIGNATED SHARES. Holders of CU Stock who do not submit a Letter of Transmittal prior to the Election Deadline must nevertheless submit a properly completed Letter of Transmittal (other than the section pertaining to the Election) and Certificates representing their CU Stock to the Exchange Agent in order to receive the Merger Consideration payable in respect of such Shares. No dividend or other distribution declared or made with respect to PCFC Stock with a record date on or after the Effective Time (as defined in the Merger Agreement) will be paid to the holder of any unsurrendered Certificate for CU Stock until the holder duly surrenders such Certificate. 7. NO LIABILITY. Neither PCFC, CU nor the Exchange Agent will be liable to any holder of Shares of CU Stock for any shares of PCFC Stock (or dividends or distributions with respect thereto) or cash delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. CONTINUED ON REVERSE SIDE C. RECEIPT OF MERGER CONSIDERATION, SPECIAL INSTRUCTIONS, ADDITIONAL COPIES, LOST CERTIFICATES AND TAXES 1. RECEIPT OF MERGER CONSIDERATION. As soon as practicable after the Effective Time and after proration procedures are completed, holders who have surrendered their Certificates to the Exchange Agent for cancellation, together with this Letter of Transmittal duly executed and completed in accordance with these instructions and such other documents as are required pursuant to such instructions, shall be entitled to receive in exchange therefor: (i) a check in the amount equal to the cash, if any, which such holder has the right to receive (including any cash in lieu of any fractional shares and any dividends or other distributions to which such holder is entitled) and (ii) a certificate or certificates representing that number of whole shares of PCFC Stock, if any, which such holder has the right to receive.

STOCK TRANSFER TAXES. If any check or certificate is to be issued in a name other than that in which the Certificates surrendered in exchange therefor are registered, it shall be a condition of such exchange that the person requesting such exchange shall pay the amount of any stock transfer taxes (whether imposed on the registered holder or such person), payable on account of the transfer to such person, to the Exchange Agent or satisfactory evidence of the payment of such taxes, or exemption therefrom, shall be submitted to the Exchange Agent before any such check or certificate is issued. 6. WITHHOLDING. Following the Merger, PCFC or the Exchange Agent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to the Merger Agreement to any holder of Shares such amounts as it is required to deduct and withhold with respect to the making of such payment, under the Internal Revenue Code of 1986, as amended, or any provision of state, local, or foreign tax law. To the extent that amounts are so withheld by PCFC or the Exchange Agent, such withheld amounts shall be treated for all purposes of the Merger Agreement as having been paid to the holder of the Shares in respect of which such deduction and withholding was made by PCFC or the Exchange Agent. 7. SUBSTITUTE FORM W-9. Under the federal income tax law, a shareholder who delivers CU Stock is required by law to provide the Exchange Agent (as payor) with such shareholder's correct Taxpayer Identification Number ("TIN") on the enclosed Substitute Form W-9. If such shareholder is an individual, the TIN is such shareholder's social security number. If the Exchange Agent is not provided with the correct TIN, the shareholder may be subject to a $50 penalty imposed by the Internal Revenue Service (the "IRS"). In addition, any cash payments that are made to such shareholder with respect to CU Stock converted in the Merger may be subject to backup withholding of 31%. Certain shareholders (including, among others, all corporations and certain foreign individuals) are not subject to these backup withholding and reporting requirements. In order for a foreign individual to qualify as an exempt recipient, such individual must submit a statement, signed under penalties of perjury, attesting to such individual's exempt status. Forms of such statements can be obtained from the Exchange Agent. If backup withholding applies with respect to a shareholder, the Exchange Agent is required to withhold 31% of any cash payments made to such shareholder. Backup withholding is not an additional tax. Rather, the tax liability of persons subject to backup withholding will be reduced by the amount of tax withheld. If withholding results in an overpayment of taxes, a refund may be obtained from the IRS. To prevent backup withholding on any cash payments that are made to a shareholder with respect to CU Stock covered hereby, the shareholder is required to notify the Exchange Agent of such shareholder's correct TIN by completing the Substitute Form W-9 certifying (i) that the TIN provided on Substitute Form W-9 is correct (or that such shareholder is awaiting a TIN) and (ii) that (a) such shareholder has not been notified by the IRS that such shareholder is subject to backup withholding as a result of a failure to report all interest or dividends or (b) the IRS has notified such shareholder that such shareholder is no longer subject to backup withholding. The shareholder is required to give the Exchange Agent the social security number or employer identification number of the record holder of the Shares tendered hereby. If such Shares are in more than one name or are not in the name of the actual owner, consult the enclosed Guidelines for Certification of Taxpayer Identification Number on Substitute Form W-9 for additional guidance concerning which number to report. If the shareholder has not been issued a TIN and has applied for a number or intends to apply for a number in the near future, such shareholder should write "Applied For" in the space provided for the TIN in Part 1, and sign and date the Substitute Form W-9. If "Applied For" is written in Part 1, and the Exchange Agent is not provided with a TIN within 60 days, the Exchange Agent will withhold 31% of all cash payments to such shareholder until a TIN is provided to the Exchange Agent. Each CU shareholder should consult his or her own accountant or tax advisor for further guidance in completing the Substitute Form W-9. ------------------------ GUIDELINES FOR CERTIFICATION OF TAXPAYER IDENTIFICATION NUMBER ON SUBSTITUTE FORM W-9 GUIDELINES FOR DETERMINING THE PROPER IDENTIFICATION NUMBER TO GIVE THE PAYOR.--Social Security numbers have nine digits separated by two hyphens: I.E., 000-00-0000.

The IRS uses the numbers for identification purposes and to help verify the accuracy of your tax return. Payors must be given the numbers whether or not recipients are required to file tax returns. Payors must generally withhold 31% of taxable interest, dividends, and certain other payments to a payee who does not furnish a taxpayer identification number. PENALTIES (1) PENALTY FOR FAILURE TO FURNISH TAXPAYER IDENTIFICATION NUMBER. If you fail to furnish your taxpayer identification number, you are subject to a penalty of $50 for each such failure unless your failure is due to reasonable cause and not to willful neglect. (2) CIVIL PENALTY FOR FALSE INFORMATION WITH RESPECT TO WITHHOLDING. If you make a false statement with no reasonable basis that results in no backup withholding, you are subject to a penalty of $500. (3) CRIMINAL PENALTY FOR FALSIFYING INFORMATION.
