RECITALS A. Issuer and Grantee have entered into an Agreement and Plan of Merger, dated as of the date hereof (the "Merger Agreement"; defined terms used but not defined herein have the meanings set forth in the Merger Agreement), providing for, among other things, the merger of Grantee with and into Issuer with Issuer as the surviving corporation in the Merger; B. As a condition and inducement to Grantee's willingness to enter into the Merger Agreement, the Stockholders Agreement and the UNUM Stock Option Agreement, Grantee has requested that Issuer agree, and Issuer has agreed, to grant Grantee the Option (as defined below); and C. As a condition and inducement to Issuer's willingness to enter into the Merger Agreement and this Agreement, Issuer has requested that Grantee agree, and Grantee has agreed, to grant Issuer an option to purchase shares of Grantee's common stock on substantially the same terms as the Option; NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth herein, Issuer and Grantee agree as follows: 1. Grant of Option. Subject to the terms and conditions set forth herein, Issuer hereby grants to Grantee an irrevocable option (the "Option", which term shall, as applicable, be deemed to refer to an option with respect to Issuer Preferred Stock (as defined in Section 2(b)) to purchase up to 26,945,874 (as adjusted as set forth herein) shares (the "Option Shares", which term shall, as applicable, be deemed to refer to Issuer Preferred Option Shares (as defined in Section 2(b)), of Common Stock, par value $1.00 per share ("Issuer Common Stock"), of Issuer at a purchase price of $35.131 (as adjusted as set forth herein) per Option Share (the "Purchase Price"). 2 2. Exercise of Option. (a) Grantee may exercise the Option, with respect to any or all of the Option Shares at any time, subject to the provisions of Section 2(c), after the occurrence of any event as a result of which the Grantee is entitled to receive the Termination Fee pursuant to Section 5.09(b) of the Merger Agreement (a "Purchase Event"); provided, however, that (i) except as provided in the last sentence of this Section 2(a), the Option will terminate and be of no further force and effect upon the earliest to occur of (A) the Effective Time, (B) 18 months after the first occurrence of a Purchase Event, and (C) termination of the Merger Agreement in accordance with its terms prior to the occurrence of a Purchase Event, unless, in the case of this clause (C), the Grantee has the right to receive a Termination Fee following such termination upon the occurrence of certain events, in which case the Option will not terminate until the later of (x) six months following the time such Termination Fee becomes payable and (y) the expiration of the period in which the Grantee has such right to receive a Termination Fee, and (ii) any purchase of Option Shares upon exercise of the Option will be subject to compliance with the HSR Act and the obtaining or making of any consents, approvals, orders, notifications, filings, expiration of applicable waiting periods or authorizations, the failure of which to have obtained or made would have the effect of making the issuance of Option Shares to Grantee illegal (the "Regulatory Approvals"). Notwithstanding the termination of the Option, Grantee will be entitled to purchase the Option Shares if it has exercised the Option in accordance with the terms hereof prior to the termination of the Option and the termination of the Option will not affect any rights hereunder which by their terms do not terminate or expire prior to or as of such termination. (b) In the event that Grantee is entitled to and wishes to exercise the Option, it will send to Issuer a written notice (an "Exercise Notice"; the date of which being herein referred to as the "Notice Date") to that effect which Exercise Notice also specifies the number of Option Shares, if any, Grantee wishes to purchase pursuant to this Section 2(b), the number of Option Shares, if any, with respect to which Grantee wishes to exercise its Cash-Out Right (as defined herein) pursuant to Section 6(c), the denominations of the certificate or certificates evidencing the Option Shares which Grantee wishes to purchase pursuant to this Section 2(b) and a date (an "Option Closing Date"), subject to the following sentence, not earlier than three business days nor later than 20 business days from the Notice Date for the closing of such purchase (an "Option Closing"); provided, however, that in the event a sufficient 3 number of shares of Issuer Common Stock are not authorized to permit the issuance by the Issuer of the number of Option Shares subject to such Exercise Notice, the Issuer shall use its best efforts to cause such number of shares of Issuer Common Stock to become authorized for issuance prior to the Option Closing Date, or, in lieu thereof, a number of shares of preferred stock, par value $1.00 per share, authorized and designated by the Issuer in accordance with the DGCL ("Issuer Preferred Stock"), which shares (or units thereof) of preferred stock shall be equal (in number and voting power) to the number of Option Shares issuable pursuant to such Exercise Notice and otherwise have terms that make such preferred stock substantially similar to Issuer Common Stock (the "Issuer Preferred Option Shares"). Any Option Closing will be at an agreed location and time in New York, New York on the applicable Option Closing Date or at such later date as may be necessary so as to comply with the first sentence of Section 2(a). (c) Notwithstanding anything to the contrary contained herein, any exercise of the Option and purchase of Option Shares shall be subject to compliance with applicable laws and regulations, which may prohibit the purchase of all the Option Shares specified in the Exercise Notice without first obtaining or making certain Regulatory Approvals. In such event, if the Option is otherwise exercisable and Grantee wishes to exercise the Option, the Option may be exercised in accordance with Section 2(b) and Grantee shall acquire the maximum number of Option Shares specified in the Exercise Notice that Grantee is then permitted to acquire under the applicable laws and regulations, and if Grantee thereafter obtains the Regulatory Approvals to acquire the remaining balance of the Option Shares specified in the Exercise Notice, then Grantee shall be entitled to acquire such remaining balance. Issuer agrees to use its reasonable efforts to assist Grantee in seeking the Regulatory Approvals. In the event (i) Grantee receives official notice that a Regulatory Approval required for the purchase of any Option Shares will not be issued or granted or (ii) such Regulatory Approval has not been issued or granted within six months of the date of the Exercise Notice, Grantee shall have the right to exercise its Cash-Out Right pursuant to Section 6(c) with respect to the Option Shares for which such Regulatory Approval will not be issued or granted or has not been issued or granted. 3. Payment and Delivery of Certificates. (a) At any Option Closing, Grantee will pay to Issuer in immediately available funds by wire transfer to a bank account 4 designated in writing by Issuer an amount equal to the Purchase Price multiplied by the number of Option Shares to be purchased at such Option Closing. (b) At any Option Closing, simultaneously with the delivery of immediately available funds as provided in Section 3(a), Issuer will deliver to Grantee a certificate or certificates representing the Option Shares to be purchased at such Option Closing, which Option Shares will be free and clear of all liens, claims, charges and encumbrances of any kind whatsoever. (c) Certificates for the Option Shares delivered at an Option Closing will have typed or printed thereon a restrictive legend which will read substantially as follows: "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR SOLD ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE. SUCH SECURITIES ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE STOCK OPTION AGREEMENT, DATED AS OF NOVEMBER 22, 1998, A COPY OF WHICH MAY BE OBTAINED FROM THE SECRETARY OF PROVIDENT COMPANIES, INC. AT ITS PRINCIPAL EXECUTIVE OFFICES." It is understood and agreed that (i) the reference to restrictions arising under the Securities Act in the above legend will be removed by delivery of substitute certificate(s) without such reference if such Option Shares have been registered pursuant to the Securities Act, such Option Shares have been sold in reliance on and in accordance with Rule 144 under the Securities Act or Grantee has delivered to Issuer a copy of a letter from the staff of the SEC, or an opinion of counsel in form and substance reasonably satisfactory to Issuer and its counsel, to the effect that such legend is not required for purposes of the Securities Act and (ii) the reference to restrictions pursuant to this Agreement in the above legend will be removed by delivery of substitute certificate(s) without such reference if the Option Shares evidenced by certificate(s) containing such reference have been sold or transferred in compliance with the provisions of this Agreement under circumstances that do not require the retention of such reference. 5 4. Representations and Warranties of Issuer. Issuer hereby represents and warrants to Grantee as follows: Authorized Stock. Issuer has taken all necessary corporate and other action to authorize and reserve and, subject to the expiration or termination of any required waiting period under the HSR Act, to permit it to issue, and, at all times from the date hereof until the obligation to deliver Option Shares upon the exercise of the Option terminates, shall have reserved for issuance, upon exercise of the Option, shares of Issuer Common Stock or, to the extent of any deficiency in the amount of authorized Issuer Common Stock, Issuer Preferred Option Shares necessary for Grantee to exercise the Option, and Issuer will take all necessary corporate action to authorize and reserve for issuance all additional shares of Issuer Common Stock and/or Issuer Preferred Option Shares or other securities which may be issued pursuant to Section 6 upon exercise of the Option. The shares of Issuer Common Stock and/or Issuer Preferred Option Shares to be issued upon due exercise of the Option, including all additional shares of Issuer Common Stock and/or Issuer Preferred Option Shares or other securities which may be issuable upon exercise of the Option or any other securities which may be issued pursuant to Section 6, upon issuance pursuant hereto, will be duly and validly issued, fully paid and nonassessable, and will be delivered free and clear of all liens, claims, charges and encumbrances of any kind or nature whatsoever, including without limitation any preemptive rights of any stockholder of Issuer. 5. Representations and Warranties of Grantee. Grantee hereby represents and warrants to Issuer that: Purchase Not for Distribution. Any Option Shares or other securities acquired by Grantee upon exercise of the Option will not be transferred or otherwise disposed of except in a transaction registered, or exempt from registration, under the Securities Act. 6. Adjustment upon Changes in Capitalization, Etc. (a) In the event of any change in the Issuer Common Stock by reason of a stock dividend, split-up, reverse stock split, merger, recapitalization, combination, exchange of shares, or similar transaction, the type and number of shares or securities subject to the Option, and the Purchase Price thereof, will be adjusted appropriately, and proper provision will be made in the agreements governing such transaction, so that Grantee will receive upon exercise of 6 the Option the number and class of shares or other securities or property that Grantee would have received in respect of Issuer Common Stock if the Option had been exercised immediately prior to such event or the record date therefor, as applicable. Subject to Section 1, and without limiting the parties' relative rights and obligations under the Merger Agreement, if any additional shares of Issuer Common Stock are issued after the date of this Agreement (other than pursuant to an event described in the first sentence of this Section 6(a)), the number of shares of Issuer Common Stock subject to the Option will be adjusted so that, after such issuance, it equates 19.9% of the number of shares of Issuer Common Stock then issued and outstanding, without giving effect to any shares subject to or issued pursuant to the Option. (b) Without limiting the parties' relative rights and obligations under the Merger Agreement, in the event that Issuer enters into an agreement (i) to consolidate with or merge into any person, other than Grantee or one of its subsidiaries, and Issuer will not be the continuing or surviving corporation in such consolidation or merger, (ii) to permit any person, other than Grantee or one of its subsidiaries, to merge into Issuer and Issuer will be the continuing or surviving corporation, but in connection with such merger, the shares of Issuer Common Stock outstanding immediately prior to the consummation of such merger will be changed into or exchanged for stock or other securities of Issuer or any other person or cash or any other property, or the shares of Issuer Common Stock outstanding immediately prior to the consummation of such merger will, after such merger, represent less than 50% of the outstanding voting securities of the merged company, or (iii) to sell or otherwise transfer all or substantially all of its assets to any person, other than Grantee or one of its subsidiaries, then, and in each such case, the agreement governing such transaction will make proper provision so that the Option will, upon the consummation of any such transaction and upon the terms and conditions set forth herein, be converted into, or exchanged for, an option with identical terms appropriately adjusted to acquire the number and class of shares or other securities or property that Grantee would have received in respect of Issuer Common Stock if the Option had been exercised immediately prior to such consolidation, merger, sale, or transfer, or the record date therefor, as applicable and make any other necessary adjustments. (c) Notwithstanding that the Issuer may at any such time not have sufficient authorized shares of Issuer Common Stock or may not have authorized and designated the 7 Issuer Preferred Option Shares in accordance with the DGCL, in each case issuable pursuant to exercise of the Option, if, at any time during the period commencing on a Purchase Event and ending on the termination of the Option in accordance with Section 2, Grantee sends to Issuer an Exercise Notice indicating Grantee's election to exercise its right (the "Cash-Out Right") pursuant to this Section 6(c), then Issuer shall pay to Grantee, on the Option Closing Date, in exchange for the cancellation of the Option with respect to such number of Option Shares as Grantee specifies in the Exercise Notice, an amount in cash equal to such number of Option Shares multiplied by the difference between (i) the average closing price, for the 10 NYSE trading days commencing on the 12th NYSE trading day immediately preceding the Notice Date, per share of Issuer Common Stock as reported on the NYSE Composite Transaction Tape (or, if not listed on the NYSE, as reported on any other national securities exchange or national securities quotation system on which the Issuer Common Stock is listed or quoted, as reported in The Wall Street Journal (Northeast edition), or, if not reported thereby, any other authoritative source) (the "Closing Price") and (ii) the Purchase Price. Notwithstanding the termination of the Option, Grantee will be entitled to exercise its rights under this Section 6(c) if it has exercised such rights in accordance with the terms hereof prior to the termination of the Option. 7. Registration Rights. Issuer will, if requested by Grantee at any time and from time to time within three years of the exercise of the Option, as expeditiously as possible prepare and file up to three registration statements under the Securities Act if such registration is necessary in order to permit the sale or other disposition of any or all shares of securities that have been acquired by or are issuable to Grantee upon exercise of the Option in accordance with the intended method of sale or other disposition stated by Grantee, including a "shelf" registration statement under Rule 415 under the Securities Act or any successor provision, and Issuer will use its best efforts to qualify such shares or other securities under any applicable state securities laws. Grantee agrees to use reasonable efforts to cause, and to cause any underwriters of any sale or other disposition to cause, any sale or other disposition pursuant to such registration statement to be effected on a widely distributed basis so that upon consummation thereof no purchaser or transferee will own beneficially more than 4.9% of the then-outstanding voting power of Issuer. Issuer will use reasonable efforts to cause each such registration statement to become effective, to obtain all consents or waivers of 8 other parties which are required therefor, and to keep such registration statement effective for such period not in excess of 180 calendar days from the day such registration statement first becomes effective as may be reasonably necessary to effect such sale or other disposition. The obligations of Issuer hereunder to file a registration statement and to maintain its effectiveness may be suspended for up to 60 calendar days in the aggregate if the Board of Directors of Issuer shall have determined that the filing of such registration statement or the maintenance of its effectiveness would require premature disclosure of material nonpublic information that would materially and adversely affect Issuer or otherwise interfere with or adversely affect any pending or proposed offering of securities of Issuer or any other material transaction involving Issuer. Any registration statement prepared and filed under this Section 7, and any sale covered thereby, will be at Issuer's expense except for underwriting discounts or commissions, brokers' fees and the fees and disbursements of Grantee's counsel related thereto. Grantee will provide all information reasonably requested by Issuer for inclusion in any registration statement to be filed hereunder. If, during the time periods referred to in the first sentence of this Section 7, Issuer effects a registration under the Securities Act of Issuer Common Stock for its own account or for any other stockholders of Issuer (other than on Form S-4 or Form S-8, or any successor form), it will allow Grantee the right to participate in such registration, and such participation will not affect the obligation of Issuer to effect demand registration statements for Grantee under this Section 7; provided that, if the managing underwriters of such offering advise Issuer in writing that in their opinion the number of shares of Issuer Common Stock requested to be included in such registration exceeds the number which can be sold in such offering, Issuer will include the shares requested to be included therein by Grantee pro rata with the shares intended to be included therein by Issuer. In connection with any registration pursuant to this Section 7, Issuer and Grantee will provide each other and any underwriter of the offering with customary representations, warranties, covenants, indemnification, and contribution in connection with such registration. 8. Limitation on Profit. (a) Notwithstanding any other provision of this Agreement, in no event shall the Grantee's Total Profit (as defined below) plus any Termination Fee paid to Grantee pursuant to Section 5.09(b) of the Merger Agreement exceed in the aggregate $250 million and, if the total amount that otherwise would be received by Grantee would exceed such amount, the Grantee, at its sole election, shall either (i) reduce the number of shares of 9 Issuer Common Stock or Issuer Preferred Stock, as the case may be, subject to the Option, (ii) deliver to the Issuer for cancellation Option Shares previously purchased by Grantee against the refund of the Purchase Price therefore, (iii) pay cash to the Issuer or (iv) any combination thereof, so that Grantee's actually realized Total Profit, when aggregated with such Termination Fee so paid to Grantee, shall not exceed $250 million after taking into account the foregoing actions. (b) Notwithstanding any other provision of this Agreement, the Option may not be exercised for a number of Option Shares as would, as of the date of exercise, result in a Notional Total Profit (as defined below) which, together with any Termination Fee theretofore paid to Grantee, would exceed $250 million; provided, that nothing in this sentence shall restrict any exercise of the Option permitted hereby on any subsequent date. (c) As used herein, the term "Total Profit" shall mean the aggregate amount (before taxes) of the following: (i) the amount received by Grantee pursuant to Issuer's repurchase of the Option (or any portion thereof) pursuant to Section 6(c), (ii)(x) the net cash amounts or the fair market value of any property received by Grantee pursuant to the sale of Option Shares (or any other securities into which such Option Shares are converted or exchanged) to any unaffiliated party, but in no case less than the fair market value of such Option Shares, less (y) the Grantee's purchase price of such Option Shares, and (iii) the net cash amounts received by Grantee on the transfer (in accordance with Section 12(g) hereof) of the Option (or any portion thereof) to any unaffiliated party. (d) As used herein, the term "Notional Total Profit" with respect to any number of Option Shares as to which Grantee may propose to exercise the Option shall be the Total Profit determined as of the date of such proposal assuming for such purpose that the Option were exercised on such date for such number of Option Shares and assuming that such Option Shares (including any units of Issuer Preferred Stock intended to equate to Issuer Common Stock), together with all other Option Shares (including any units of Issuer Preferred Stock intended to equate to Issuer Common Stock) held by Grantee and its affiliates as of such date, were sold for cash at the closing market price on the NYSE for the Issuer Common Stock as of the close of business on the preceding trading day (less customary brokerage commissions.) 10 9. Transfers. The Option Shares may not be sold, assigned, transferred, or otherwise disposed of except (i) in an underwritten public offering as provided in Section 7 or (ii) to any purchaser or transferee who would not, to the knowledge of the Grantee after reasonable inquiry, immediately following such sale, assignment, transfer or disposal beneficially own more than 4.9% of the then-outstanding voting power of the Issuer; provided, however, that Grantee shall be permitted to sell any Option Shares if such sale is made pursuant to a tender or exchange offer that has been approved or recommended by a majority of the members of the Board of Directors of Issuer (which majority shall include a majority of directors who were directors as of the date hereof). 10. Listing. If Issuer Common Stock or any other securities to be acquired upon exercise of the Option are then listed on the NYSE (or any other national securities exchange or national securities quotation system), Issuer, upon the request of Grantee, will promptly file an application to list the shares of Issuer Common Stock or other securities to be acquired upon exercise of the Option on the NYSE (and any such other national securities exchange or national securities quotation system) and will use reasonable efforts to obtain approval of such listing as promptly as practicable. 11. Loss or Mutilation. Upon receipt by Issuer of evidence reasonably satisfactory to it of the loss, theft, destruction or mutilation of this Agreement, and (in the case of loss, theft or destruction) of reasonably satisfactory indemnification, and upon surrender and cancellation of this Agreement, if mutilated, Issuer will execute and deliver a new Agreement of like tenor and date. Any such new Agreement executed and delivered will constitute an additional contractual obligation on the part of Issuer, whether or not the Agreement so lost, stolen, destroyed, or mutilated shall at any time be enforceable by anyone. 12. Miscellaneous. (a) Expenses. Except as otherwise provided in the Merger Agreement, each of the parties hereto will bear and pay all costs and expenses incurred by it or on its behalf in connection with the transactions contemplated hereunder, including fees and expenses of its own financial consultants, investment bankers, accountants, and counsel.

Any agreement on the part of a party to waive any provision of this Agreement, or to extend the time for performance, will be valid only if set forth in an instrument in writing signed on behalf of such party. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise will not constitute a waiver of such rights.

This Agreement, the UNUM Stock Option Agreement, the Merger Agreement (including the documents and instruments attached thereto as exhibits or schedules or delivered in connection therewith), the Stockholders Agreement, the Confidentiality Agreement and the Letter Agreement (i) constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, between the parties with respect to the subject matter of this Agreement, and (ii) except as provided in Section 8.06 of the Merger Agreement, are not intended to confer upon any person other than the parties any rights or remedies.
