The Company and its subsidiaries ("UNUM") are the leading providers of group long term disability insurance ("group LTD") in the United States and the United Kingdom. UNUM is also a major provider of employee benefits, individual disability insurance and special risk reinsurance. UNUM also markets long term care and retirement income products. UNUM is based in Portland, Maine and through its affiliates has offices in North America, the United Kingdom and the Pacific Rim. The Company's principal executive offices are located at 2211 Congress Street, Portland, Maine 04122 and its telephone number is (207) 770-2211. The operations of the following subsidiaries account for substantially all of UNUM's consolidated assets and revenues: UNUM Life Insurance Company of America ("UNUM America"), the leading provider of group disability insurance in the nation and a provider of employee benefits, long term care and retirement products; First UNUM Life Insurance Company (New York state only) ("First UNUM"); Commercial Life Insurance Company, a leader in special risk insurance and professional association insurance marketing; UNUM Limited, the leading group disability insurance provider in the United Kingdom; Duncanson & Holt, Inc., a leading accident and health reinsurance underwriting manager; Colonial Life & Accident Insurance Company ("Colonial"), a leader in payroll-deducted voluntary employee benefits offered to employees at their worksites; and UNUM Japan Accident Insurance Company Limited. BUSINESS SEGMENTS UNUM reports its operations principally in four business segments: Disability Insurance, Special Risk Insurance, Colonial Products and Retirement Products. Corporate includes transactions that are generally non-insurance related and interest expense on corporate borrowings. DISABILITY INSURANCE SEGMENT. The Disability Insurance segment, which in 1995 accounted for 60.0% of UNUM's revenues and 56.8% of its income before income taxes, includes disability products offered in North America, the United Kingdom and Japan including: group LTD, individual disability, group short term disability, association group disability, disability reinsurance and long term care insurance. Group LTD is the Disability Insurance segment's principal product. UNUM America and First UNUM target sales of group LTD to executive, administrative and management personnel, and other professionals. Since 1976, UNUM America and First UNUM combined have been the United States' leading provider of group LTD according to EMPLOYEE BENEFIT PLAN REVIEW, a recognized industry publication. UNUM Limited targets group LTD sales to management personnel, other professionals, and technical and skilled artisans. UNUM Limited was the leading provider for 1995 of group LTD insurance in the United Kingdom, as reported by Employers Re. International. SPECIAL RISK INSURANCE SEGMENT. The Special Risk Insurance segment in 1995 accounted for 18.2% of UNUM's revenues and 15.8% of its income before income taxes. The Special Risk Insurance segment includes group life, special risk accident insurance, non-disability reinsurance operations, reinsurance underwriting management operations and other special risk insurance products. COLONIAL PRODUCTS SEGMENT. The Colonial Products segment in 1995 accounted for 12.8% of UNUM's revenues and 23.0% of its income before income taxes. The Colonial Products segment includes Colonial and affiliates. Colonial, the principal subsidiary, markets a broad line of payroll-deducted, voluntary benefits to employees at their worksites, while focusing on accident and sickness, cancer and life products. RETIREMENT PRODUCTS SEGMENT. The Retirement Products segment accounted for 8.7% of UNUM's revenues and 11.9% of its income before income taxes in 1995. This segment markets and services tax- 3 sheltered annuities in UNUM America and First UNUM. This segment also includes guaranteed investment contracts, deposit administration accounts, 401(k) plans, individual life and group medical insurance, all of which are no longer actively marketed by UNUM. RECENT DEVELOPMENTS During the first quarter of 1996, UNUM America and First UNUM entered into an agreement for the sale of their respective group tax-sheltered annuity ("TSA") businesses to The Lincoln National Life Insurance Company ("Lincoln Life"), a part of Lincoln National Corporation, and to a new New York insurance subsidiary of Lincoln Life. The sale, which is subject to regulatory approvals, involves approximately 1,700 group contractholders and assets under management of approximately $3 billion. The agreement initially contemplates the reinsurance of these contracts under an indemnity reinsurance arrangement. These contracts will then be reinsured pursuant to an assumption reinsurance arrangement upon consent of the TSA contractholders and/or participants. The purchase price (ceding commission) at closing is expected to be approximately $70 million. It is anticipated that it will take several months to obtain the necessary approvals and otherwise close the sale. There is no guarantee that the sale will close. On February 7, 1996, UNUM announced plans to merge Commercial Life Insurance Company into UNUM America to accelerate growth of its special risk business, increase its commitment to the association group business and to improve operating and capital efficiencies. The merger is expected to become effective on December 31, 1996, subject to regulatory approvals. On December 29, 1993, UNUM filed suit in the United States District Court for the District of Maine, seeking a federal income tax refund. The suit is based on a claim for a deduction in certain prior tax years, for $652 million in cash and stock distributed to policyholders in connection with the 1986 conversion of Union Mutual Life Insurance Company to a stock company. UNUM has fully paid, and provided for in prior years' financial statements, the tax at issue in this litigation. On May 23, 1996, the District Court issued its decision that the distribution in question was not a deductible expenditure. UNUM believes its claims are meritorious, and expects to appeal the decision to the Court of Appeals for the First Circuit. The ultimate recovery, if any, cannot be determined at this time.

UNUM evaluates total expected return after consideration of associated expenses and losses, within criteria established for each product line. Product line investment strategies are developed to complement business risks by meeting the liquidity and solvency requirements of each product. UNUM purchases assets with maturities, expected cash flows and prepayment conditions that are consistent with these strategies. The 4 nature and quality of the types of investments comply with policies established by management, which are more stringent overall than the statutes and regulations imposed by the jurisdictions in which UNUM's insurance subsidiaries are licensed. UNUM's investments are reported in the consolidated financial statements at net realizable value or net of any applicable allowances for probable losses. During the second quarter of 1995, UNUM sold virtually all of the common stock portfolio of its United States subsidiaries, primarily due to consideration of statutory capital requirements associated with investment in common stocks and to increase future investment income. UNUM has reinvested the proceeds from the sale of the common stock portfolio primarily in investment grade fixed income assets. Dependent on capital considerations and market conditions, UNUM may invest in equity securities in the future. In November 1995, the FASB issued "A Guide to Implementation of Statement 115 on Accounting for Certain Investments in Debt and Equity Securities," which provided a one-time opportunity to reassess the appropriateness of the classifications of securities described in FAS 115, and to reclassify fixed maturities from the held to maturity category without calling into question the intent to hold other debt securities to maturity in the future. On December 31, 1995, UNUM reassessed its fixed maturity portfolio and, as allowed under the implementation guidance, reclassified fixed maturities with an amortized cost of $6,082.8 million and a related net unrealized gain of $393.0 million from the held to maturity category to available for sale. At December 31, 1995, the fixed maturity portfolio included $139.4 million of below investment grade bonds (below "Baa") recorded at fair value, which represented 1.5% of the fixed maturity portfolio, and had an associated amortized cost of $133.8 million. At December 31, 1994, the carrying value of below investment grade bonds included in the fixed maturity portfolio was $193.8 million, which represented 2.5% of the fixed maturity portfolio, and had an associated market value of $193.4 million. The percentage of mortgage loans delinquent 60 days or more on a contract delinquency basis was 0.2% and 1.8% at December 31, 1995, and 1994, respectively. 5 SELECTED CONSOLIDATED FINANCIAL DATA OF THE COMPANY YEAR ENDED DECEMBER 31, ------------------------------------------------------------- 1995 1994 1993 1992 1991 ---------- ---------- ---------- ---------- ---------- (DOLLARS IN MILLIONS, EXCEPT PER SHARE DATA) INCOME STATEMENT DATA Revenues Premiums.................................................. $ 3,018.2 $ 2,721.3 $ 2,474.1 $ 2,142.4 $ 1,938.9 Net investment income (a)................................. 1,031.4 815.8 839.8 850.7 811.6 Fees and other income..................................... 73.3 75.5 83.1 55.4 34.0 ---------- ---------- ---------- ---------- ---------- Total revenues.............................................. 4,122.9 3,612.6 3,397.0 3,048.5 2,784.5 Benefits and expenses Benefits to policyholders................................. 2,493.0 2,239.0 1,775.7 1,532.6 1,387.1 Interest credited......................................... 227.4 242.7 281.0 328.4 357.7 Operating expenses........................................ 728.2 713.0 675.6 590.9 554.8 Commissions............................................... 369.9 355.9 326.8 298.9 258.8 Increase in deferred policy acquisition costs.............

Fixed charges consist of interest expense and the estimated interest portion of rent expense. 6 SELECTED CONSOLIDATED SEGMENT INCOME STATEMENT DATA OF THE COMPANY YEAR ENDED DECEMBER 31, --------------------------------------------------- 1995 1994 1993 1992 1991 -------- -------- -------- -------- -------- (DOLLARS IN MILLIONS) Premiums and other income: Disability Insurance Segment.............................. $1,879.9 $1,716.2 $1,547.9 $1,339.8 $1,214.6 Special Risk Insurance Segment............................ 702.3 607.1 559.4 432.8 368.5 Colonial Products Segment................................. 475.1 441.3 407.4 371.9 325.4 Retirement Products Segment 34.1 31.4 42.5 52.5 64.4 Corporate................................................. 0.1 0.8 -- 0.8 -- -------- -------- -------- -------- -------- Total premiums and other income......................... 3,091.5 2,796.8 2,557.2 2,197.8 1,972.9 -------- -------- -------- -------- -------- Net investment income: (a) Disability Insurance Segment.............................. 592.9 400.3 369.8 370.5 333.8 Special Risk Insurance Segment............................ 48.4 40.7 34.8 32.2 26.5 Colonial Products Segment................................. 52.2 32.6 41.4 35.4 38.5 Retirement Products Segment............................... 323.7 338.0 387.6 408.7 411.3 Corporate................................................. 14.2 4.2 6.2 3.9 1.5 -------- -------- -------- -------- -------- Total net investment income............................. 1,031.4 815.8 839.8 850.7 811.6 -------- -------- -------- -------- -------- Total revenues.......................................... 4,122.9 3,612.6 3,397.0 3,048.5 2,784.5 -------- -------- -------- -------- -------- Benefits and expenses: Disability Insurance Segment.............................. 2,255.8 2,060.3 1,603.6 1,446.6 1,306.4 Special Risk Insurance Segment............................ 690.4 581.9 555.3 418.7 355.2 Colonial Products Segment................................. 439.6 411.2 378.4 346.8 306.4 Retirement Products Segment 312.3 327.4 375.8 427.5 484.4 Corporate................................................. 42.9 33.2 23.6 10.4 12.5 -------- -------- -------- -------- -------- Total benefits and expenses............................. 3,741.0 3,414.0 2,936.7 2,650.0 2,464.9 -------- -------- -------- -------- -------- Income (loss) before income taxes and cumulative effects of accounting changes: Disability Insurance Segment.............................. 217.0 56.2 314.1 263.7 242.0 Special Risk Insurance Segment............................ 60.3 65.9 38.9 46.3 39.8 Colonial Products Segment................................. 87.7 62.7 70.4 60.5 57.5 Retirement Products Segment............................... 45.5 42.0 54.3 33.7 (8.7) Corporate.................................................

(b) Effective January 1, 1993, the Company adopted Financial Accounting Standard No. 106, "Employers' Accounting for Postretirement Benefits Other than Pensions," which decreased net income by $32.1 million, or $0.40 per share, and Financial Accounting Standard No. 109, "Accounting for Income Taxes," which increased net income by $20.0 million, or $0.25 per share. 7 USE OF PROCEEDS Except as set forth in a Prospectus Supplement, the Company intends to use the net proceeds from the sale of the Securities for general corporate purposes, including working capital, capital expenditures, investment in subsidiaries, refinancing of debt, possible future business acquisitions and for the repurchase of its Common Stock. The Company does not have any present plans, and is not engaged in any negotiations, for the use of any such proceeds, or the issuance of Common Stock, in any future acquisition. Any proposal to use proceeds from any offering of Securities in connection with an acquisition will be disclosed in the Prospectus Supplement relating to such offering. DESCRIPTION OF DEBT SECURITIES The following description sets forth certain general terms and provisions of the Debt Securities to which any Prospectus Supplement may relate. The particular terms of the Debt Securities offered by any Prospectus Supplement and the extent, if any, to which such general provisions may not apply to the Debt Securities so offered will be described in the Prospectus Supplement relating to such Debt Securities. The Senior Debt Securities are to be issued under an Indenture, dated as of September 15, 1990 (the "Senior Indenture"), between UNUM Corporation (for purposes of this "Description of Debt Securities," exclusive of its subsidiaries, the "Company") and The Chase Manhattan Bank, N.A., as trustee. The Subordinated Debt Securities are to be issued under a separate Indenture dated as of May 1, 1995 (the "Subordinated Indenture") between the Company and Mellon Bank, N.A., as trustee. The Senior Indenture and the Subordinated Indenture are sometimes referred to collectively as the "Indentures." Copies of the Senior Indenture and the Subordinated Indenture are filed or incorporated by reference as exhibits to the Registration Statement of which this Prospectus is a part. The Chase Manhattan Bank, N.A. and Mellon Bank, N.A. are hereinafter referred to as the "Trustee." The following summaries of certain provisions of the Senior Debt Securities, the Subordinated Debt Securities and the Indentures do not purport to be complete and are subject to, and are qualified in their entirety by reference to, all the provisions of the Indentures applicable to a particular series of Debt Securities, including the definitions therein of certain terms. Wherever particular Sections, Articles or defined terms of the Indentures are referred to, such Sections, Articles or defined terms are incorporated herein by reference. Article and Section references used herein are references to the applicable Indenture. Except as otherwise indicated, the terms of the Senior Indenture and the Subordinated Indenture are identical. Capitalized terms not otherwise defined herein shall have the meaning given in the Indentures. GENERAL The Indentures do not limit the aggregate principal amount of Debt Securities which may be issued thereunder and each Indenture provides that Debt Securities may be issued thereunder from time to time in one or more series. The Debt Securities will be unsecured. Unless otherwise specified in the Prospectus Supplement, the Senior Debt Securities when issued will be unsubordinated obligations of the Company and will rank equally and ratably with all other unsecured and unsubordinated indebtedness of the Company. The Subordinated Debt Securities when issued will be subordinated in right of payment to the prior payment in full of all Senior Indebtedness (as defined below) of the Company, as described under "Subordination of Subordinated Debt Securities" and in the Prospectus Supplement applicable to an offering of Subordinated Debt Securities. Since the Company is a holding company, the right of the Company, and hence the right of creditors of the Company (including the Holders of Debt Securities), to participate in any distribution of the assets of any subsidiary upon its liquidation or reorganization or otherwise is necessarily subject to the prior claims of creditors of the subsidiary, except to the extent that claims of the Company itself as a creditor of the subsidiary may be recognized. Reference is made to the Prospectus Supplement relating to the particular Debt Securities offered thereby (the "Offered Debt Securities") which sets forth whether the Offered Debt Securities shall be 8 Senior Debt Securities or Subordinated Debt Securities, and further sets forth the following terms, where applicable, of the Offered Debt Securities: (1) the title of the Offered Debt Securities; (2) any limit on their aggregate principal amount; (3) whether they are to be issuable in temporary or permanent global form; (4) the price(s) (expressed as a percentage of the aggregate principal amount thereof) at which they will be issued; (5) the date(s) on which they will mature; (6) the rate(s) (which may be fixed, floating or adjustable) at which they will bear interest, if any, and the date from which such interest will accrue; (7) the dates on which such interest will be payable and the Regular Record Dates for such Interest Payment Dates; (8) any mandatory or optional sinking fund or analogous provisions; (9) any index or formula used to determine the amount of payments of principal of and premium, if any, and interest; (10) the date, if any, after which and the price(s) at which the Company may redeem them at its option; (11) the currency or currencies (including composite currencies) of payment of principal of and premium, if any, and interest thereon if other than U.S. dollars (the "Specified Currency"); (12) the terms and conditions, if any, pursuant to which the Subordinated Debt Securities are convertible into or exchangeable for Common Stock or other securities or property of the Company; (13) the Person to whom any interest on the Offered Debt Securities will be payable, if other than the Person in whose name such Offered Debt Securities are registered on any Regular Record Date; (14) the place or places where principal of (and premium, if any) and interest, if any, on Offered Debt Securities will be payable; (15) if other than denominations of $1,000 and any integral multiple thereof, the denominations in which the Offered Debt Securities will be issuable; (16) any event or events of default applicable with respect to the Offered Debt Securities in addition to those provided in the applicable Indenture; (17) any other covenant or warranty included for the benefit of the Offered Debt Securities in addition to (and not inconsistent with) those included in the applicable Indenture for the benefit of Debt Securities of all series, or any other covenant or warranty included for the benefit of the Offered Debt Securities in lieu of any covenant or warranty included in the Indentures for the benefit of Debt Securities of all series or any provision that any covenant or warranty included in the applicable Indenture for the benefit of Debt Securities of all series shall not be for the benefit of the Offered Debt Securities, or any combination of such covenants, warranties or provisions; and (18) any other terms. (Section 301) Debt Securities may also be issued under the Indentures upon the exercise of Warrants. See "Description of Warrants." The Indentures do not contain any provisions that afford Holders of the Debt Securities protection in the event of a highly leveraged or similar transaction involving the Company. Offered Debt Securities may be issued at a substantial discount to their principal amount (the "Original Issue Discount Securities"). Certain United States Federal income tax and other considerations applicable to Original Issue Discount Securities, and to Offered Debt Securities that are denominated in other than U.S. dollars, will be described in the applicable Prospectus Supplement. The Indentures provide the Company with the ability, in addition to the ability to issue Offered Debt Securities with terms different from those of Debt Securities previously issued, to "reopen" a previous issue of a series of Debt Securities and issue additional Offered Debt Securities of such series. (Section 301) DENOMINATIONS, REGISTRATION AND TRANSFER Unless otherwise provided in an applicable Prospectus Supplement with respect to a series of Offered Debt Securities, Offered Debt Securities denominated in U.S. dollars will be issued only in denominations of $1,000 or any integral multiple thereof without coupons. The Prospectus Supplement relating to a series of Offered Debt Securities denominated in a foreign or composite currency will specify the denominations thereof. (Section 302) Offered Debt Securities of any series will be exchangeable for other Offered Debt Securities of the same series containing identical terms and provisions and of a like aggregate principal amount and containing identical terms and provisions of different authorized denominations. (Section 305) Offered Debt Securities may be issuable under the Indentures in temporary or permanent global form. (Section 202) See "Global Securities." 9 Unless otherwise indicated in an applicable Prospectus Supplement, the principal office of the Trustee in The City of New York will be designated as the Company's Paying Agent for payments with respect to Debt Securities. Any other Paying Agents in the United States initially designated by the Company for the Offered Debt Securities will be named in the related Prospectus Supplement. The Company may at any time designate additional Paying Agents or rescind the designation of any Paying Agents or approve a change in the office through which any Paying Agent acts, except that the Company will be required to maintain a Paying Agent in each Place of Payment for such series. All monies paid by the Company to a Paying Agent for the payment of principal of and premium, if any, and interest, if any, on any Debt Security which remains 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 Offered Debt Security will thereafter look only to the Company for payment thereof. (Section 1003) GLOBAL SECURITIES If any Offered Debt Securities are issuable in temporary or permanent global form, the applicable Prospectus Supplement will describe the circumstances, if any, under which beneficial owners of interests in any such permanent global Debt Security may exchange such interests for definitive Offered Debt Securities of such series and of like tenor and principal amount in any authorized form and denomination. Principal of and any premium and interest on a permanent global Debt Security will be payable in the manner described in the applicable Prospectus Supplement. CERTAIN COVENANTS IN THE INDENTURES LIMITATIONS ON SALES OF RESTRICTED SUBSIDIARIES' CAPITAL STOCK. The Company will not sell, transfer or otherwise dispose of any shares of capital stock of a Restricted Subsidiary (other than directors' qualifying shares or sales to Restricted Subsidiaries), and it will not permit any Restricted Subsidiary to sell, transfer or otherwise dispose of any shares of capital stock of any other Restricted Subsidiary (other than for directors' qualifying shares or sales or other transfers to the Company or to a Restricted Subsidiary), unless the entire capital stock of such Restricted Subsidiary at the time owned by the Company and its Restricted Subsidiaries shall be disposed of at the same time for a consideration consisting of cash or other property, which, in the opinion of the Board of Directors of the Company, is at least equal to the fair value thereof. (Section 1006) For purposes of the Indentures, "Restricted Subsidiary" means each of UNUM Life Insurance Company of America, First UNUM Life Insurance Company, and Colonial Companies, Inc., as well as any successor to all or a principal part of the business of any such subsidiary, any subsidiary which owns or holds capital stock of any such subsidiary and any other subsidiary which the Company's Board of Directors designates as a Restricted Subsidiary. (Section 101) The Restricted Subsidiaries accounted for approximately 90% of the consolidated revenues of the Company during 1995 and approximately 91% of the consolidated assets of the Company at December 31, 1995. LIMITATIONS ON LIENS ON RESTRICTED SUBSIDIARIES' CAPITAL STOCK. The Company will not, and it will not permit any Restricted Subsidiary at any time directly or indirectly to, create, assume, incur, or permit to exist any indebtedness secured by a pledge, lien, or other encumbrance on the capital stock of any Restricted Subsidiary without making effective provision whereby the Debt Securities then outstanding (and, if the Company so elects, any other indebtedness ranking on a parity with the Debt Securities) shall be equally and ratably secured with such secured indebtedness so long as such other indebtedness shall be secured. (Section 1007) CONVERSION RIGHTS The terms on which Subordinated Debt Securities of any series are convertible into or exchangeable for Common Stock or other securities or property of the Company will be set forth in the Prospectus Supplement relating thereto. Such terms shall include provisions as to whether conversion or exchange is mandatory, at the option of the Holder or at the option of the Company, and may include provisions 10 pursuant to which the number of shares of Common Stock or other securities of the Company to be received by the Holders of Subordinated Debt Securities would be calculated according to the market price of Common Stock or other securities of the Company as of a time stated in the Prospectus Supplement. The conversion price of any Subordinated Debt Securities of any series that is convertible into Common Stock of the Company may be adjusted for any stock dividends, stock splits, reclassification, combinations or similar transactions, as set forth in the applicable Prospectus Supplement. (Article Fourteen). SUBORDINATION OF SUBORDINATED DEBT SECURITIES Unless otherwise indicated in the Prospectus Supplement, the following provisions will apply to the Subordinated Debt Securities. The Subordinated Debt Securities will, to the extent set forth in the Subordinated Indenture, be subordinate in right of payment to the prior payment in full of all Senior Indebtedness. Upon any payment or distribution of assets to creditors upon any liquidation, dissolution, winding up, reorganization, assignment for the benefit of creditors, marshalling of assets or any bankruptcy, insolvency, debt restructuring or similar proceedings in connection with any insolvency or bankruptcy proceeding of the Company, the Holders of Senior Indebtedness will first be entitled to receive payment in full of principal of (and premium, if any) and interest, if any, on such Senior Indebtedness before the Holders of the Subordinated Debt Securities will be entitled to receive or retain any payment in respect of the principal of (and premium, if any) or interest, if any, on the Subordinated Debt Securities. (Section 1302) By reason of such subordination, in the event of liquidation or insolvency, creditors of the Company may recover less, ratably, than Holders of Senior Indebtedness and may recover more, ratably, than the Holders of the Subordinated Debt Securities. In the event of the acceleration of the maturity of any Subordinated Debt Securities, the Holders of all Senior Indebtedness outstanding at the time of such acceleration will first be entitled to receive payment in full of all amounts due thereon before the Holders of the Subordinated Debt Securities will be entitled to receive any payment upon the principal of (or premium, if any) or interest, if any, on the Subordinated Debt Securities. (Section 1303) No payments on account of principal (or premium, if any) or interest, if any, in respect of the Subordinated Debt Securities may be made if there shall have occurred and be continuing a default in any payment with respect to Senior Indebtedness, or an event of default with respect to any Senior Indebtedness resulting in the acceleration of the maturity thereof, or if any judicial proceeding shall be pending with respect to any such default. (Section 1304) For purposes of the subordination provisions, the payment, issuance and delivery of cash, property or securities (other than stock and certain subordinated securities of the Company) upon conversion of a Subordinated Debt Security will be deemed to constitute payment on account of the principal of such Subordinated Debt Security. The Subordinated Indenture does not limit or prohibit the incurrence of additional Senior Indebtedness, which may include indebtedness that is senior to the Subordinated Debt Securities, but subordinate to other obligations of the Company. The Senior Debt Securities constitute Senior Indebtedness under the Subordinated Indenture. "Senior Indebtedness" is defined to include all amounts due on and obligations in connection with any of the following, whether outstanding at the date of execution of the Subordinated Indenture or thereafter incurred or created: (a) indebtedness, obligations and other liabilities (contingent or otherwise) of the Company for money borrowed, or evidenced by bonds, debentures, notes or similar instruments; 11 (b) reimbursement obligations and other liabilities (contingent or otherwise) of the Company with respect to letters of credit, bankers' acceptances issued for the account of the Company or with respect to interest rate protection agreements or currency exchange or purchase agreements; (c) obligations and liabilities (contingent or otherwise) in respect of leases by the Company as lessee which, in conformity with generally accepted accounting principles, are accounted for as capitalized lease obligations on the balance sheet of the Company; (d) all direct or indirect guarantees or similar agreements in respect of, and obligations or liabilities (contingent or otherwise) to purchase or otherwise acquire or otherwise to assure a creditor against loss of the Company in respect of, indebtedness, obligations or liabilities of another Person described in clauses (a) through (c); (e) any indebtedness described in clauses (a) through (d) secured by any mortgage, pledge, lien or other encumbrance existing on property which is owned or held by the Company, regardless of whether the indebtedness secured thereby shall have been assumed by the Company; and (f) any and all deferrals, renewals, extensions and refundings of, or amendments, modifications or supplements to, any indebtedness, obligation or liability of the kind described in clauses (a) through (e); unless in any case in the instrument creating or evidencing such indebtedness, obligation, liability, guaranty, assumption, deferral, renewal, extension or refunding, it is provided that such indebtedness, obligation, liability, guaranty, assumption, deferral, renewal, extension or refunding involved is not senior in right of payment to the Subordinated Debt Securities or that such indebtedness is PARI PASSU with or junior to the Subordinated Debt Securities. (Section 101) The Prospectus Supplement may further describe the provisions, if any, applicable to the subordination of the Subordinated Debt Securities of a particular series. CONSOLIDATION, MERGER AND SALE OF ASSETS The Company, without the consent of any Holders of Outstanding Debt Securities, may consolidate or merge with or into any Person, or transfer or lease its assets substantially as an entirety to any Person, or may acquire or lease the assets of any Person, provided that: (a) the successor formed by such consolidation or into which the Company is merged or which acquires or leases the assets of the Company substantially as an entirety is organized under the laws of any United States jurisdiction and assumes the Company's obligations on the Debt Securities and under the applicable Indenture; (b) after giving effect to the transaction, no Event of Default (and no event which, after notice or lapse of time or both, would become an Event of Default) shall have happened and be continuing; and (c) certain other conditions are met. (Article Eight) EVENTS OF DEFAULT Under the Indentures, the following will be Events of Default with respect to Debt Securities of a particular series: (a) the Company defaults in the payment of interest on any Debt Security of that series when due and payable and the Default continues for a period of 30 days; (b) the Company defaults in the payment of any principal of and premium, if any, on any Debt Security of that series when due and payable at maturity, upon redemption or otherwise, or in the deposit of any sinking fund payment when due by the terms of a Debt Security of that series; (c) the Company fails to comply with or perform any of its other agreements, covenants or warranties in the Debt Securities of that series or the Indenture in respect of Debt Securities of that series and the Default continues for 60 days after written notice as provided in the applicable Indenture; (d) there shall be a default by the Company or any Restricted Subsidiary under any (i) debt for money borrowed (including Debt Securities of any series other than that series), (ii) mortgage, indenture or other instrument under which there may be issued or may be secured or evidenced any indebtedness for money borrowed, (iii) guarantee of payment for money borrowed or (iv) debt evidenced by bonds, debentures, notes or other similar instruments (excluding trade accounts payable or accrued liabilities arising in the normal course of business which are not overdue by more 12 than 90 days or which are being contested in good faith) and such default shall result in such indebtedness becoming due prior to its stated maturity; PROVIDED, HOWEVER, a default shall exist under this clause (d) only if all such defaults relate to such indebtedness or such guarantees with an aggregate principal amount in excess of $5,000,000, the acceleration of which has not been rescinded or annulled within 10 days after written notice as provided in the applicable Indenture; (e) certain events of bankruptcy, insolvency or reorganization of the Company or any Restricted Subsidiary; and (f) any other Event of Default provided with respect to Debt Securities of that series. (Section 501) The applicable Trustee or the Holders of at least 25% in principal amount of the Outstanding Debt Securities of that series (each series acting as a separate class) may declare all unpaid principal of and accrued interest (or such lesser amount as may be provided for in the Debt Securities of that series) on all then Outstanding Debt Securities of that series to be due and payable immediately if an Event of Default (other than one in (e) above) with respect to Debt Securities of such series shall occur and be continuing at the time of declaration. If an Event of Default as specified in (e) above occurs, all unpaid principal and accrued interest (or such lesser amount as may be provided for in the Debt Securities of that series) shall IPSO FACTO become and be immediately due and payable without any other declaration or act on the part of the Trustee or any Holder. (Section 502) At any time after a declaration of acceleration has been made with respect to Debt Securities of any series, the Holders of a majority in principal amount of the Outstanding Debt Securities of that series may rescind any declaration of acceleration with respect to the Debt Securities of that series and its consequences, (a) if the rescission would not conflict with any judgment or decree; (b) if all existing Events of Defaults with respect to Debt Securities of that series have been cured or waived except non-payment of principal or interest on Debt Securities of that series that has become due solely because of the acceleration; and (c) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefore in such Debt Securities has been paid. (Section 502) Any Event of Default with respect to Debt Securities of any series may be waived by the Holders of a majority in principal amount of the Outstanding Debt Securities of that series, except in a case of failure to pay principal or premium, if any, or interest on, or deposit of any sinking fund payment with respect to, any Debt Security of that series for which payment or deposit had not been subsequently made or in respect of a covenant or provision which cannot be modified or amended without the consent of the Holder of each Outstanding Debt Security of such series affected. (Section 504) If any event which is, or after notice or lapse of time or both would become an Event of Default (a "Default") occurs with respect to Debt Securities of any series and it is known to the applicable Trustee, the Trustee shall mail to Holders of Debt Securities of that series a notice of Default within 90 days after it occurs unless such Default shall have been cured or waived, PROVIDED that except in the case of a Default in the payment of the principal of or premium, if any, or interest on, any Debt Security of any series or in the making of any sinking fund payment payable with respect to Debt Securities of any series, the Trustee may withhold the notice if and so long as the board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee in good faith determines that withholding the notice is in the interests of Holders of Debt Securities of that series and PROVIDED, FURTHER, that in the case of any Default of the character specified in clause (c) under "Events of Default" with respect to Debt Securities of any series, no notice to Holders shall be given until at least 30 days after the occurrence thereof. (Section 602) Reference is made to the Prospectus Supplement relating to any series of Debt Securities which are Original Issue Discount Securities for the particular provisions relating to the principal amount of such Original Issue Discount Securities due upon the occurrence of any Event of Default and the continuation thereof. The Holders of a majority in principal amount of the Outstanding Debt Securities of a series may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee with respect to Debt Securities of such series, 13 PROVIDED that the Trustee may refuse to follow any directions that conflict with any law or the Indenture, are unduly prejudicial to the rights of other Holders of that series, or would involve the Trustee in personal liability. (Section 505) In case an Event of Default shall occur and be continuing, the Trustee shall exercise such of its rights and powers under the applicable Indenture and use the same degree of care and skill in their exercise as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. (Section 601) Before proceeding to exercise any right or power under the applicable Indenture at the direction of such Holders, the Trustee will be entitled to receive from such Holders security or indemnity satisfactory to it against the costs, expenses and liabilities which might be incurred by it in complying with any such direction. (Section 603) MODIFICATION AND WAIVER With certain exceptions, modification or amendment of the Indentures or the rights of Holders of the Debt Securities of any series may be effected by the Company and the Trustee with the consent of the Holders of at least 66 2/3% in principal amount of the Outstanding Debt Securities of each series affected thereby, PROVIDED that no such modification or amendment may, without the written consent of the Holder of each Outstanding Debt Security affected thereby, (a) change the Stated Maturity of the principal of, or any installment of principal of, or interest on, any Debt Security; (b) reduce the principal amount of, or the interest on, any Debt Security or any premium payable upon the redemption thereof or reduce the amount of principal of an Original Issue Discount Security which could be declared due and payable upon an acceleration; (c) change the Place of Payment or coin or currency of any payment of principal, any premium or interest on any Debt Security; (d) impair the right to institute suit for the enforcement of any payment on or with respect to any Debt Security; (e) reduce the percentage in principal amount of the Outstanding Debt Securities of any series, the consent of whose Holders is required to approve any supplemental indenture, to waive compliance with certain provisions of the applicable Indenture or certain defaults thereunder and their consequences, or to reduce quorum or voting requirements applicable to meetings of Holders; (f) in the case of Subordinated Debt Securities, adversely change the right to convert or exchange, including decreasing the conversion rate or increasing the conversion price of such Subordinated Debt Securities; (g) in the case of the Subordinated Indenture, modify the subordination provisions in a manner adverse to the Holders of any Subordinated Debt Securities; or (h) modify the foregoing requirements in (a) through (g) above, requiring the consent of each Holder of each Outstanding Debt Security affected thereby, or the percentage of such Holders required to waive past defaults, or the percentage of such Holders that may rescind an acceleration, except to increase any such percentage, and except to provide that other provisions of the Indentures cannot be modified or waived without the consent of the Holder of each Outstanding Debt Security affected thereby. (Section 902) Except with respect to certain fundamental provisions, the Holders of at least a majority in principal amount of Outstanding Debt Securities of any series may, with respect to such series, waive past defaults under the Indentures and waive compliance by the Company with certain provisions of the Indentures. (Section 513) SATISFACTION AND DISCHARGE OF INDENTURES The Indentures generally provide that the Company may terminate certain of its obligations under the Debt Securities of any series and under the Indentures (with respect to such series) if (i) all the Debt Securities of such series previously authenticated and delivered (other than lost, destroyed or stolen Debt Securities that have been replaced or paid or for whose payment money has been deposited in trust) have been delivered to the Trustee for cancellation and the Company has paid all sums payable by it thereunder, (ii) such Debt Securities of such series have matured or will mature within one year or all of them are to be called for redemption within one year under arrangements satisfactory to the Trustee for giving the notice of redemption and the Company irrevocably deposits with the Trustee money or U.S. Government Obligations sufficient to pay principal of, premium, if any, and interest on the Outstanding Debt Securities of such series that are due or will become due upon redemption or maturity, as the case 14 may be, and to pay all other sums payable by it thereunder or (iii) upon compliance with certain conditions specified in the Indentures, 123 days after the Company makes the deposit with the Trustee of money or U.S. Government Obligations specified in clause (ii). In such case, Holders of the Debt Securities must look to the deposited money for payment. (Section 401) The Indentures further provide that if the Company has made the election provided by clause (iii) above, it may elect either (a) to defease and be discharged from any and all obligations with respect to the Debt Securities of such series, except for the obligations to register the transfer or exchange of such Debt Securities, to replace temporary or mutilated, destroyed, lost or stolen Debt Securities, to maintain an office or agency in respect of the Debt Securities, and to hold moneys for payment in trust ("legal defeasance") or (b) to be released from its obligations with respect to the Debt Securities of such series under the covenant default (except with respect to the covenant to pay principal and interest) and cross-acceleration provisions under "Events of Default" and from the restrictions described under certain covenants in the Indentures, including "Limitations on Sales of Restricted Subsidiaries' Capital Stock" and "Limitations on Liens on Restricted Subsidiaries' Capital Stock," and, in the case of Subordinated Debt Securities, the provisions described under "Subordination of Subordinated Debt Securities" ("covenant defeasance"). As a condition to legal defeasance or covenant defeasance, the Company must deliver to the Trustee an opinion of counsel (as specified in the Indentures) to the effect that the Holders of the Debt Securities of such series will not recognize income, gain or loss for United States Federal income tax purposes as a result of such legal defeasance or covenant defeasance and will be subject to United States Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance or covenant defeasance had not occurred. In the case of legal defeasance under clause (a) or covenant defeasance under clause (b) above, a ruling of the Internal Revenue Service may be delivered in lieu of such opinion. (Section 401) Under current United States Federal income tax law, legal defeasance would likely be treated as a taxable exchange of such Debt Securities for interests in the defeasance trust. As a consequence, a Holder would recognize gain or loss equal to the difference between the Holder's tax basis for such Debt Securities and the value of the Holder's interest in the defeasance trust, and thereafter would be required to include in income its share of the income, gain and loss of the defeasance trust. Under current Federal income tax law, covenant defeasance would likely not be treated as a taxable exchange of such Debt Securities. Purchasers of such Debt Securities should consult their tax advisors with respect to the more particular tax consequences to them of such legal defeasance and covenant defeasance, including the applicability and effect of United States Federal income and other tax law. The Company may exercise its legal defeasance option with respect to the Debt Securities of such series, notwithstanding its prior exercise of its covenant defeasance option. If the Company exercises its legal defeasance option, payment of such Debt Securities may not be accelerated because of an Event of Default. If the Company exercises its covenant defeasance option, payment of such Debt Securities may not be accelerated because of the covenant default (except with respect to the covenant to pay principal and interest) and cross-acceleration provisions or certain of the covenants, including those noted under clause (b) above. However, if such an acceleration were to occur because of other defaults, the realizable value at the acceleration date of the money and U.S. Government Obligations in the defeasance trust could be less than the principal and interest then due on such Debt Securities, because the required deposit in the defeasance trust is based upon scheduled cash flows rather than market value, which will vary depending upon interest rates and other factors. (Section 401) The term "U.S. Government Obligations" is defined to mean direct obligations of the United States for the payment of which its full faith and credit is pledged, or obligations of a person controlled or supervised by and acting as an agency or instrumentality of the United States and the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States which, in either case, are not callable or redeemable at the option of the issuer thereof, and shall also include a depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with 15 respect to any such U.S. Government Obligations or a specific payment of principal of or interest on any such U.S. Government Obligations held by such custodian for the account of the holder of such depositary receipt, PROVIDED that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government Obligations or the specific payment of principal of or interest on the U.S. Government Obligations evidenced by such depositary receipt. (Section 101) CONCERNING THE TRUSTEES The Company maintains banking relationships in the ordinary course of business with The Chase Manhattan Bank, N.A. and Mellon Bank, N.A. In addition, Mellon Bank, N.A. is a participant in the Company's $500 million revolving credit facility entered into as of December 13, 1994.

DESCRIPTION OF PREFERRED STOCK The following description sets forth certain general terms and provisions of the Preferred Stock to which any Prospectus Supplement may relate. Certain other terms of a particular series of Preferred Stock will be described in the Prospectus Supplement relating to that series. If so indicated in the Prospectus Supplement, the terms of any such series may differ from the terms set forth below. The description of certain provisions of the Preferred Stock set forth below and in any Prospectus Supplement does not purport to be complete and is subject to and qualified in its entirety by reference to the Company's Certificate of Incorporation and the certificate of designation relating to each such series of Preferred Stock, which will be filed with the Commission in connection with the offering of such series of Preferred Stock. GENERAL Under the Company's Certificate of Incorporation, the Board of Directors is authorized to fix and determine the terms, limitations and relative rights and preferences of any class of preferred stock, including, without limitation, any voting rights thereof, to divide and issue any of the classes of preferred stock in series, and to fix and determine the variations among series to the extent permitted by law. The Company has authorized 1,000,000 shares of Junior Participating Preferred Stock for issuance upon 16 exercise of certain preferred share purchase rights associated with each share of outstanding Common Stock as provided in the Rights Agreement. See "Description of Common Stock--Share Purchase Rights Plan,--Description of Junior Participating Preferred Stock." The Preferred Stock shall have the dividend, liquidation, redemption and voting rights set forth below unless otherwise provided in the Prospectus Supplement relating to a particular series of Preferred Stock. Reference is made to the Prospectus Supplement relating to a particular series of Preferred Stock offered thereby for specific terms including: (1) the designation and the number of shares offered; (2) the amount of liquidation preference per share; (3) the price at which such Preferred Stock will be issued; (4) the dividend rate (or method of calculation), the dates on which dividends will be payable, whether such dividends will be cumulative or noncumulative and, if cumulative, the dates from which dividends will commence to cumulate; (5) any redemption or sinking fund provisions; (6) any conversion or exchange rights; and (7) any additional voting, dividend, liquidation, redemption, sinking fund and other rights, preferences, privileges, limitations and restrictions. The Preferred Stock offered hereby will be issued in one or more series. The holders of Preferred Stock will have no preemptive rights. Any shares of Preferred Stock sold hereunder will be fully paid and nonassessable upon issuance against full payment of the purchase price therefor. Unless otherwise specified in the Prospectus Supplement relating to a particular series of Preferred Stock, each series of Preferred Stock will rank on a parity as to dividends and liquidation rights in all respects with each other series of Preferred Stock (other than the Junior Participating Preferred Stock). DIVIDEND RIGHTS Holders of the Preferred 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, cash dividends at such rates and on such dates as are set forth in the Prospectus Supplement relating to such series of Preferred Stock. Different series of the Preferred Stock may be entitled to dividends at different rates or based upon different methods of determination. Such rate may be fixed or variable or both. Each such dividend 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 or a duly authorized committee thereof. Dividends on any series of the Preferred Stock may be cumulative or noncumulative, as provided in the Prospectus Supplement relating thereto. RIGHTS UPON LIQUIDATION In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company, the holders of each series of Preferred Stock will be entitled to receive out of assets of the Company available for distribution to stockholders, before any distribution of assets is made to holders of Common Stock or any other class of stock ranking junior to such series of the Preferred Stock upon liquidation, liquidating distributions in the amount set forth in the Prospectus Supplement relating to such series of Preferred Stock plus an amount equal to accrued and unpaid dividends for the then current dividend period and, if such series of the Preferred Stock is cumulative, for all dividend periods prior thereto, all as set forth in the Prospectus Supplement with respect to such shares. REDEMPTION The terms, if any, on which shares of a series of Preferred Stock may be subject to optional or mandatory redemption, in whole or in part, will be set forth in the Prospectus Supplement relating to such series. CONVERSION The terms, if any, on which shares of any series of Preferred Stock are convertible into Common Stock will be set forth in the Prospectus Supplement relating thereto. Such terms may include provisions 17 for conversion, either mandatory, at the option of the holder, or at the option of the Company, in which case the number of shares of Common Stock to be received by the holders of Preferred Stock would be calculated as of a time and in the manner stated in the Prospectus Supplement. TRANSFER AGENT AND REGISTRAR The transfer agent, registrar and dividend disbursement agent for the Preferred Stock will be designated in the applicable Prospectus Supplement. The registrar for shares of Preferred Stock will send notices to shareholders of any meetings at which holders of the Preferred Stock have the right to elect directors of the Company or to vote on any other matter. VOTING RIGHTS The holders of Preferred Stock of a series offered hereby will not be entitled to vote except as indicated in the Prospectus Supplement relating to such series of Preferred Stock or as required by applicable law. DESCRIPTION OF COMMON STOCK GENERAL Subject to the rights of the holders of any shares of the Company's Preferred Stock which may at the time be outstanding, holders of Common Stock are entitled to such dividends as the Board of Directors may declare out of funds legally available therefor. The holders of Common Stock will possess exclusive voting rights in the Company, except to the extent the Board of Directors specifies voting power with respect to any Preferred Stock issued. Except as hereinafter described, holders of Common Stock are entitled to one vote for each share of Common Stock, but will not have any right to cumulate votes in the election of directors. In the event of liquidation, dissolution or winding up of the Company, the holders of Common Stock are entitled to receive, after payment of all of the Company's debts and liabilities and of all sums to which holders of any Preferred Stock may be entitled, the distribution of any remaining assets of the Company. Holders of the Common Stock will not be entitled to preemptive rights with respect to any shares which may be issued. Any shares of Common Stock sold hereunder will be fully paid and non-assessable upon issuance against full payment of the purchase price therefor. First Chicago Trust Company of New York is the transfer agent for the Common Stock. The Common Stock is listed on the New York Stock Exchange and the Pacific Stock Exchange under the symbol "UNM." CERTAIN PROVISIONS The provisions of the Company's Certificate of Incorporation and By-Laws which are summarized below may be deemed to have an anti-takeover effect and may delay, defer or prevent a tender offer or takeover attempt that a stockholder might consider in such stockholder's best interest, including those attempts that might result in a premium over the market price for the shares held by stockholders. CLASSIFIED BOARD. The Board of Directors is divided into three classes that are elected for staggered three-year terms. A director may be removed by the stockholders, but only for cause, and only by the affirmative vote of the holders, voting as a single class, of 80% or more of the total number of votes entitled to be cast by all holders of the voting stock which shall include all capital stock of the Company which by its terms may vote on all matters submitted to stockholders of the Company generally. ISSUANCE OF PREFERRED STOCK. Pursuant to the Certificate of Incorporation, the Board of Directors by resolution may establish one or more series of Preferred Stock having such number of shares, designation, relative voting rights, dividend rates, liquidation and other rights, preferences and limitations as may be fixed by the Board of Directors without any further stockholder approval. Such rights, preferences, privileges and limitations as may be established could have the effect of impeding or discouraging the acquisition of control of the Company. 18 BUSINESS COMBINATIONS. In addition, the Certificate of Incorporation and By-Laws of the Company contain supermajority voting provisions relating to the approval of business combinations with certain stockholders. Pursuant to the Company's Certificate of Incorporation, any Business Combination (as defined therein, which term includes a merger, sale of all or substantially all its assets, the adoption of a plan of liquidation and similar extraordinary corporate transactions) with (i) any person (other than the Company, its subsidiaries, certain employee benefit plans of the Company and the trustees of such plans) who is the beneficial owner of 10% or more of the UNUM Voting Stock (as defined below) or (ii) any person who is an Affiliate or Associate (as defined in Rule 12b-2 of the Exchange Act) of the Company and who was the beneficial owner of 10% or more of the UNUM Voting Stock at any time in the two years prior to the date in question (each such person, a "UNUM Interested Stockholder") must be approved by a supermajority vote, unless the Business Combination has been approved by the vote of a majority of the Continuing Directors (as defined below) of the Company's Board of Directors. "UNUM Voting Stock" means all capital stock of the Company which by its terms may vote on all matters submitted to stockholders of the Company generally. "Continuing Director" means any Board of Directors member who while serving as a Board of Directors member is not an Affiliate or Associate or representative of the UNUM Interested Stockholder and who was a Board of Directors member before the UNUM Interested Stockholder became such and includes certain successors to such Board of Directors members. The required supermajority vote consists of the affirmative vote of the holders of (i) 80% or more of the UNUM Voting Stock, voting together as a single class, and (ii) at least a majority of the shares of UNUM Voting Stock not held by the UNUM Interested Stockholder, voting together as a single class. AMENDMENTS TO THE CERTIFICATE OF INCORPORATION. Under the Certificate of Incorporation, the amendment of, repeal of or adoption of any provision inconsistent with certain provisions of the Certificate of Incorporation relating to (i) the election of the Board of Directors, its powers and related matters requires the affirmative vote of the holders of at least 80% of the outstanding UNUM Voting Stock, voting together as a single class, and (ii) Business Combinations with UNUM Interested Stockholders and the required votes for amendments of the Certificate of Incorporation requires the affirmative vote of the holders specified in clause (i) above and the affirmative vote of the holders of at least a majority of the outstanding UNUM Voting Stock which is not beneficially owned by any UNUM Interested Stockholder, voting together as a single class. The above supermajority voting requirements do not apply to any amendment, repeal or adoption recommended by the Board of Directors of the Company if a majority of the Board of Directors of the Company then in office consists of persons who would be eligible to serve as Continuing Directors. AMENDMENTS TO THE BY-LAWS. The Certificate of Incorporation provides that the By-Laws may be amended by the affirmative vote of a majority of directors present at a meeting of the Board of Directors at which a quorum is present or by the affirmative vote of the holders of at least 80% of all outstanding UNUM Voting Stock, voting together as a single class. STOCKHOLDER PROPOSAL PROCEDURES. The By-Laws require any stockholder who wants to present a proposal for action by the stockholders at an annual meeting to deliver a written notice to the Secretary of the Company. To be timely, a stockholder's notice must be delivered to, or mailed and received at, the principal executive offices of the Company, not less than 60 days nor more than 90 days prior to the date of the annual meeting, unless less than 75 days' notice or prior public disclosure of the date of such meeting has been given or made to the stockholders, in which case a stockholder's notice must be received no later than the close of business on the 15th day following the day on which such notice was mailed or such disclosure was made. SHARE PURCHASE RIGHTS PLAN On March 13, 1992, the Board of Directors of the Company adopted a stockholder rights plan and declared a dividend distribution of one right (a "Right") for each outstanding share of Common Stock to 19 stockholders of record at the close of business on March 23, 1992. Each Right entitles the registered holder to purchase from the Company a unit consisting of one one-hundredth of a share (a "Unit") of Junior Participating Preferred Stock, at a purchase price of $150 per Unit, subject to adjustment (the "Purchase Price"). The terms of the Junior Participating Preferred Stock are such that one Unit is essentially equivalent to one share of Common Stock. The description and terms of the Rights are set forth in a Rights Agreement, dated as of March 13, 1992 and amended as of June 19, 1996 (as amended, the "Rights Agreement"), between the Company and First Chicago Trust Company of New York, as rights agent (the "Rights Agent"). Initially, the Rights are attached to all outstanding Common Stock certificates, and no separate certificates evidencing Rights ("Rights Certificates") are distributed. The Rights will separate from the Common Stock and a "Distribution Date" will occur upon the earlier of (i) ten (10) days following a public announcement that a person or group of affiliated or associated persons (an "Acquiring Person") has acquired, or obtained the right to acquire, beneficial ownership of 10% or more of the outstanding shares of Common Stock, except for persons or a group of affiliated or associated persons who become the beneficial owner of 10% or more of the outstanding shares of Common Stock solely as a result of a reduction in the number of shares of Common Stock outstanding due to a repurchase of shares by the Company unless such person or group thereafter acquires additional shares representing 1% or more of the outstanding Common Stock (the "Stock Acquisition Date") or (ii) ten (10) business days (or such later date as may be determined by the Board of Directors) following the announcement of a tender offer or exchange offer that would result in a person or group beneficially owning 10% or more of such outstanding shares of Common Stock. However, if the Board of Directors of the Company determines that any person who would otherwise be an Acquiring Person has become such inadvertently, then such person will not become an Acquiring Person if certain conditions are satisfied, including divestiture by such person of beneficial ownership of the shares of Common Stock that would have otherwise caused such person to become an Acquiring Person. Until the Distribution Date, (i) the Rights will be evidenced by the Common Stock certificates and will be transferred with and only with such Common Stock certificates, (ii) new Common Stock certificates issued after March 23, 1992 contain a notation incorporating the Rights Agreement by reference, and (iii) the surrender for transfer of any certificates for Common Stock outstanding will also constitute the transfer of the Rights associated with the Common Stock represented by such certificates. The Rights are not exercisable until the Distribution Date and will expire at the close of business on March 13, 2002, unless earlier redeemed by the Company as described below (the "Expiration Date"). In the event that (i) a Person becomes an Acquiring Person (except pursuant to an offer for all outstanding shares of Common Stock which at least a majority of the members of the Board of Directors who are not officers of the Company and who are not representatives, nominees, affiliates or associates of an Acquiring Person determine to be fair to and otherwise in the best interests of the Company and its stockholders (a "Fair Offer")) or (ii) an Acquiring Person or any of its affiliates or associates shall merge into or otherwise combine with the Company in a transaction in which the Company is the surviving corporation and the Common Stock remains outstanding and unchanged, each holder of a Right will thereafter have the right to receive, upon exercise, Common Stock (or, in certain circumstances, cash, property or other securities of the Company or a reduction in the Purchase Price) having a value equal to two times the exercise price of the Right. Notwithstanding any of the foregoing, following the occurrence of any of the events set forth in this paragraph, all Rights that are, or (under certain circumstances specified in the Rights Agreement) were, beneficially owned by an Acquiring Person or an associate or affiliate of an Acquiring Person will be null and void. However, Rights are not exercisable following the occurrence of any of the events set forth in this paragraph until such time as the Rights are no longer redeemable by the Company as set forth below. In the event that, at any time following the Stock Acquisition Date, (i) the Company is acquired in a merger or other business combination transaction in which the Company is not the surviving corporation 20 (other than a merger described in the preceding paragraph or a merger which follows, and is at the same price as, a Fair Offer), or (ii) 50% or more of UNUM's assets or earning power is sold or transferred, each holder of a Right (except Rights which previously have become null and void as set forth above) shall thereafter have the right to receive, upon exercise, common stock of the acquiring company having a value equal to two times the exercise price of the Right. The events set forth in this paragraph and in the preceding paragraph are referred to as the "Triggering Events." At any time after there is an Acquiring Person and prior to the acquisition by such Acquiring Person of 50% or more of the outstanding Common Stock, the Board of Directors may exchange the Rights (other than Rights owned by the Acquiring Person which have become null and void), in whole or in part, at an exchange ratio of one share of Common Stock or one Unit of Junior Participating Preferred Stock (or a share or unit of another series of the Company's preferred stock having equivalent rights, preferences and privileges) per Right (subject to adjustment). At any time until ten (10) days following the Stock Acquisition Date, the Company may redeem the Rights in whole, but not in part, at a price of $.01 per Right (the "Redemption Price"), which is payable in cash, Common Stock or other consideration deemed appropriate by the Board of Directors. Immediately upon the action of the Board of Directors ordering redemption of the Rights, the Rights will terminate and the only right of the holders of Rights will be to receive the Redemption Price. The Purchase Price payable, and the number of shares of Junior Participating Preferred Stock or other securities or property issuable, upon exercise of the Rights are subject to adjustment from time to time to prevent dilution. Until a Right is exercised, the holder thereof, as such, will have no rights as a stockholder of the Company, including, without limitation, the right to vote or to receive dividends. Stockholders may, depending upon the circumstances, recognize taxable income in the event that the Rights become exercisable for Common Stock (or other consideration) or for common stock of the acquiring company as set forth above. The Rights have certain anti-takeover effects. The Rights will cause substantial dilution to a person or group that attempts to acquire the Company in a manner which causes the Rights to become exercisable unless the offer is conditioned on substantially all the Rights being acquired. This potential dilution may have the effect of delaying, deferring or discouraging attempts to acquire control of the Company which are not approved by the Company's Board of Directors. However, the Rights should not interfere with any merger or other business combination approved by the Company's Board of Directors. DESCRIPTION OF JUNIOR PARTICIPATING PREFERRED STOCK GENERAL. In connection with the Rights Agreement, 1,000,000 shares of Junior Participating Preferred Stock have been reserved and authorized for issuance by the Board of Directors of the Company. No shares of Junior Participating Preferred Stock are outstanding as of the date of this Prospectus. The following statements with respect to the Junior Participating Preferred Stock do not purport to be complete and are subject to the detailed provisions of the Certificate of Incorporation and the certificate of designation relating to the Junior Participating Preferred Stock (the "Certificate of Designation"), which are filed as exhibits to the Registration Statement of which this Prospectus is a part. RANKING. The Junior Participating Preferred Stock shall rank junior to all other series of the Company's Preferred Stock as to the payment of dividends and the distribution of assets, unless the terms of any such series shall provide otherwise. DIVIDENDS AND DISTRIBUTIONS. Subject to the prior and superior rights of the holders of any shares of any series of Preferred Stock ranking prior and superior to the shares of Junior Participating Preferred Stock with respect to dividends, the holders of shares of Junior Participating Preferred Stock shall be entitled to receive, when, as and if declared by the Board of Directors out of funds legally available for 21 that purpose, quarterly dividends payable in cash on the 19th day of February, May, August and November in each year (each such date being referred to herein as "Quarterly Dividend Payment Date") commencing on the first Quarterly Dividend Payment Date after the first issuance of a share or fraction of a share of Junior Participating Preferred Stock, in an amount per share (rounded to the nearest cent) equal to the greater of (a) $5.00 or (b) (subject to adjustment upon certain dilutive events) 100 times the aggregate per share amount of all cash dividends, and 100 times the aggregate per share amount (payable in kind) of all non-cash dividends or other distributions other than a dividend payable in shares of Common Stock or a subdivision of the outstanding shares of Common Stock (by reclassification or otherwise), declared on the Common Stock, since the immediately preceding Quarterly Dividend Payment Date, or, with respect to the first Quarterly Dividend Payment Date, since the first issuance of any share or fraction of a share of Junior Participating Preferred Stock. The Company shall declare a dividend or distribution on the Junior Participating Preferred Stock immediately after it declares a dividend or distribution on the Common Stock (other than a dividend payable in shares of Common Stock); provided that, in the event no dividend or distribution shall have been declared on the Common Stock during the period between any Quarterly Dividend Payment Date and the next subsequent Quarterly Dividend Payment Date, a dividend of $5.00 per share on the Junior Participating Preferred Stock shall nevertheless be payable on such subsequent Quarterly Dividend Payment Date. VOTING RIGHTS. The holders of shares of Junior Participating Preferred Stock shall have the following voting rights: (a) subject to adjustment upon certain dilutive events, each share of Junior Participating Preferred Stock shall entitle the holder thereof to 100 votes on all matters submitted to a vote of the stockholders of the Company; (b) except as otherwise provided by the Certificate of Designation or by law, the holders of shares of Junior Participating Preferred Stock and the holders of shares of Common Stock shall vote together as one class on all matters submitted to a vote of stockholders of the Company; and (c) if at any time dividends on any Junior Participating Preferred Stock shall be in arrears in an amount equal to six (6) quarterly dividends thereon, the occurrence of such contingency shall mark the beginning of a period (herein called a "default period") which shall extend until such time when all accrued and unpaid dividends for all previous quarterly dividend periods and for the current quarterly dividend period on all shares of Junior Participating Preferred Stock then outstanding shall have been declared and paid or set apart for payment. During each default period, all holders of Preferred Stock (including holders of the Junior Participating Preferred Stock) with dividends in arrears in an amount equal to six (6) quarterly dividends thereon, voting as a class, irrespective of series, shall have the right to elect two (2) Directors, until the expiration of a default period. LIQUIDATION, DISSOLUTION OR WINDING UP. Upon any liquidation (voluntary or otherwise), dissolution or winding up of the Company, no distribution shall be made to the holders of shares of stock ranking junior (either as to dividends or upon liquidation, dissolution or winding up) to the Junior Participating Preferred Stock unless, prior thereto, the holders of shares of Junior Participating Preferred Stock shall have received $250 per share, plus an amount equal to accrued and unpaid dividends and distributions thereon, whether or not declared, to the date of such payment (the "Series A Liquidation Preference"). Following the payment of the full amount of the Series A Liquidation Preference, no additional distributions shall be made to the holders of shares of Junior Participating Preferred Stock unless, prior thereto, the holders of shares of Common Stock shall have received an amount per share (the "Common Adjustment") equal to the quotient obtained by dividing (i) the Series A Liquidation Preference by (ii) 100 (as appropriately adjusted to reflect such events as stock splits, stock dividends and recapitalizations with respect to the Common Stock) (such number in clause (ii) immediately above being referred to as the "Adjustment Number"). Following the payment of the full amount of the Series A Liquidation Preference and the Common Adjustment in respect of all outstanding shares of Junior Participating Preferred Stock and Common Stock, respectively, holders of Junior Participating Preferred Stock and 22 holders of shares of Common Stock shall receive their ratable and proportionate share of the remaining assets to be distributed in the ratio of the Adjustment Number to one (1) with respect to such Preferred Stock and Common Stock, on a per share basis, respectively. In the event, however, that there are not sufficient assets available to permit payment in full of the Series A Liquidation Preference and the liquidation preferences of all other series of preferred stock, if any, which rank on a parity with the Junior Participating Preferred Stock, then such remaining assets shall be distributed ratably to the holders of such parity shares in proportion to their respective liquidation preferences. In the event, however, that there are not sufficient assets available to permit payment in full of the Common Adjustment, then such remaining assets shall be distributed ratably to the holders of Common Stock. CONSOLIDATION, MERGER, ETC. In case the Company shall enter into any consolidation, merger, combination or other transaction in which the shares of Common Stock are exchanged for or changed into other stock or securities, cash and/or any other property, then in any such case, the shares of Junior Participating Preferred Stock shall at the same time be similarly exchanged or changed in an amount per share (subject to adjustment upon certain dilutive events) equal to 100 times the aggregate amount of stock, securities, cash and/or any other property (payable in kind), as the case may be, into which or for which each share of Common Stock is changed or exchanged. REDEMPTION. The outstanding shares of Junior Participating Preferred Stock may be redeemed at the option of the Board of Directors in whole, but not in part, at any time, or from time to time, at a cash price per share equal to 105 percent of (i) the product of the Adjustment Number times the Average Market Value (as such term is hereinafter defined) of the Common Stock, plus (ii) all dividends which on the redemption date have accrued on the shares to be redeemed and have not been paid, or declared and a sum sufficient for the payment thereof set apart, without interest. The "Average Market Value" is the average of the closing sale prices of the Common Stock during the 30-day period immediately preceding the date before the redemption date on the Composite Tape for New York Stock Exchange Listed Stocks, or, if such stock is not quoted on the Composite Tape, on the New York Stock Exchange, or, if such stock is not listed on such Exchange, on the principal United States securities exchange registered under the Exchange Act, on which such stock is listed, or, if such stock is not listed on any such exchange, the average of the closing sale prices with respect to a share of Common Stock during such 30-day period, as quoted on the National Association of Securities Dealers, Inc. Automated Quotations System or any system then in use, or, if no such quotations are available, the fair market value of the Common Stock as determined by the Board of Directors in good faith. DESCRIPTION OF WARRANTS The Company may issue Warrants, including Warrants to purchase Debt Securities, Preferred Stock, Common Stock or other securities of the Company. Warrants may be issued independently or together with any such securities of the Company and may be attached to or separate from such securities of the Company. 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 shall be set forth in the Prospectus Supplement relating to Warrants being offered pursuant thereto. WARRANTS The applicable Prospectus Supplement will describe the terms of Warrants offered thereby, the Warrant Agreement relating to such Warrants and the warrant certificates representing such Warrants, including the following: (1) the title of such Warrants; (2) the securities of the Company for which such Warrants are exercisable; (3) the aggregate number of such Warrants; (4) the price or prices at which such Warrants will be issued; (5) the currency or currencies, including composite currencies or currency units, in which the price of such Warrants may be payable; (6) the procedures and conditions relating to 23 the exercise of such Warrants; (7) the designation and terms of any related securities of the Company with which such Warrants are issued, and the number of such Warrants issued with each such security; (8) the date, if any, on and after which such Warrants and the related securities of the Company will be separately transferable; (9) the date on which the right to exercise such Warrants shall commence, and the date on which such right shall expire; (10) the maximum or minimum number of such Warrants which may be exercised at any time; (11) a discussion of material United States Federal income tax considerations, if any; (12) any other terms of such Warrants and terms, procedures and limitations relating to the exercise of such Warrants; and (13) the terms of the securities of the Company purchasable upon exercise of such Warrants. Warrant certificates will be exchanged 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 exercisable for Debt Securities 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 (or premium, if any) or interest, if any, on the Debt Securities purchasable upon such exercise. Prior to the exercise of their Warrants for shares of Preferred Stock or Common Stock, holders of such Warrants will not have any rights of holders of the Preferred Stock or Common Stock purchasable upon such exercise and will not be entitled to dividend payments, if any, or voting rights of the Preferred Stock or Common Stock purchasable upon such exercise. EXERCISE OF WARRANTS Each Warrant will entitle the holder of Warrants to purchase for cash such principal amount or such number of securities of the Company at such exercise price as shall in each case be set forth in, or be determinable as set forth in, the Prospectus Supplement relating to the Warrants offered thereby. After the close of business on the expiration date, unexercised Warrants will become void. Warrants may be exercised as set forth in the Prospectus Supplement relating to the Warrants offered thereby. Upon receipt of payment and the warrant certificate properly completed and duly executed at the corporate trust office of the Warrant Agent or any other office indicated in the Prospectus Supplement, the Company will, as soon as practicable, forward the securities purchasable upon such exercise. If less than all of the Warrants represented by such warrant certificate are exercised, a new warrant certificate will be issued for the remaining Warrants.

An investment in Debt Securities denominated in other than U.S. dollars entails significant risks that are not associated with a similar investment in a security denominated in U.S. dollars. Such risks include, without limitation, the possibility of significant changes in rates of exchange between the U.S. dollar and the various foreign currencies or composite currencies, and the possibility of the imposition or modification of foreign exchange controls by either the U.S. or foreign governments. Such risks generally depend on economic and political events over which the Company has no control. In recent years, rates of exchange between the U.S. dollar and certain foreign currencies have been highly volatile, and such volatility may be expected to continue in the future. Fluctuations in any particular exchange rate that have occurred in the past are not necessarily indicative, however, of fluctuations in the rate that may occur during the term of any Debt Security. Depreciation of the Specified Currency other than U.S. dollars against the U.S. dollar would result in a decrease in the effective yield of such Debt Security below its coupon rate, and in certain circumstances could result in a loss to the investor on a U.S. dollar basis. Governments have imposed from time to time and may in the future impose exchange controls that could affect exchange rates as well as the availability of a specified foreign currency at a Debt Security's 24 maturity. Even if there are no actual exchange controls, it is possible that the Specified Currency for any particular Debt Security would not be available at such Debt Security's maturity. In that event, the Company will repay such Debt Security at maturity in U.S. dollars on the basis of the most recently available Exchange Rate. This Prospectus does not describe all the risks of an investment in Debt Securities denominated in other than U.S. dollars. Prospective investors should consult their own financial and legal advisors as to the risks entailed by an investment in Debt Securities denominated in other than U.S. dollars. Debt Securities denominated in other than U.S. dollars are not an appropriate investment for investors who are unsophisticated about foreign currency transactions. Currently, there are limited facilities in the United States for conversion of U.S. dollars into certain foreign currencies, and vice versa. Unless otherwise specified in the Prospectus Supplement, Debt Securities denominated in other than U.S. dollars or European currency units will not be sold in, or to residents of, the country issuing the Specified Currency in which particular Debt Securities are denominated. The information set forth in this Prospectus is directed to prospective purchasers who are United States residents, and the Company disclaims any responsibility to advise prospective purchasers who are residents of countries other than the United States as to any matters that may affect the purchase, holding, or receipt of payments of principal of and interest on the Debt Securities. Such persons should consult their own financial and legal advisors with regard to such matters. GOVERNING LAW AND JUDGMENTS. The Debt Securities will be governed by and construed in accordance with the laws of the State of New York. Under the Judiciary Law of the State of New York, a judgment in an action based upon an obligation denominated in a currency other than U.S. dollars will be rendered in the foreign currency of the underlying obligation and converted into U.S. dollars at the rate of exchange prevailing on the date of the entry of the judgment or decree. EXCHANGE RATE AND CONTROLS FOR SPECIFIED CURRENCIES For any Debt Security denominated in other than U.S. dollars, the Prospectus Supplement relating to such Debt Securities will contain information concerning exchange rates. The information concerning exchange rates will be furnished as a matter of information only and should not be regarded as indicative of the rate of or trends in future fluctuations in currency exchange rates. PLAN OF DISTRIBUTION The Company may sell Securities to or through underwriters, and also may sell Securities directly to other purchasers or through agents. The distribution of the Securities may be effected from time to time in one or more transactions at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to such prevailing market prices or at negotiated prices. In connection with the sale of Securities, underwriters may receive compensation from the Company or from purchasers of Securities, for whom they may act as agents, in the form of discounts, concessions, or commissions. Underwriters may sell 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 from the purchasers for whom they may act as agents. Underwriters, dealers, and agents that participate in the distribution of Securities may be deemed to be underwriters, and any discounts or commissions they receive from the Company, and any profit on the resale of Securities they realize may be deemed to be underwriting discounts and commissions, under the Securities Act. Any such underwriter or agent will be identified, and any such compensation received from the Company will be described, in the Prospectus Supplement. 25 Each series of Securities will be a new issue with no established trading market, other than the Common Stock which is listed on the New York Stock Exchange and the Pacific Stock Exchange. Any Common Stock sold pursuant to a Prospectus Supplement will be listed on such exchanges, subject to official notice of issuance. The Company may elect to list any series of Debt Securities, Preferred Stock or Warrants on an exchange, but is not obligated to do so. It is possible that one or more underwriters may make a market in a series of Securities, but will not be obligated to do so and may discontinue any market making at any time without notice. Therefore, no assurance can be given as to the liquidity of the trading market for the Securities. Under agreements the Company may enter into, underwriters, dealers, and agents who participate in the distribution of Securities maybe entitled to indemnification by the Company against certain liabilities, including liabilities under the Securities Act. Underwriters, dealers and agents may engage in transactions with, or perform services for, or be customers of, the Company in the ordinary course of business. If so indicated in the Prospectus Supplement, the Company will authorize underwriters or other persons acting as the Company's agents to solicit offers by certain institutions to purchase Securities from the Company pursuant to contracts providing for payment and delivery on a future date. Institutions with which such contracts may be made include commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and others, but in all cases such institutions must be approved by the Company. The obligations of any purchaser under any such contract will be subject to the condition that the purchase of the Securities shall not at the time of delivery be prohibited under the laws of the jurisdiction to which such purchaser is subject. The underwriters and such other agents will not have any responsibility in respect of the validity or performance of such contracts. VALIDITY OF THE SECURITIES The validity of the Securities will be passed upon for the Company by Skadden, Arps, Slate, Meagher & Flom, New York, New York. The validity of the Securities in connection with any offering thereof will be passed upon for the Company by Kevin J. Tierney, Senior Vice President, Secretary and General Counsel of the Company and by Skadden, Arps, Slate, Meagher & Flom, New York, New York with respect to certain matters of New York law, and for the underwriters or agents by Sullivan & Cromwell, New York, New York. Mr. Tierney owns less than one percent of the Company's Common Stock. EXPERTS The consolidated financial statements of the Company and its subsidiaries included in the Company's Annual Report on Form 10-K for the year ended December 31, 1995, have been incorporated herein by reference in reliance upon the report of Coopers & Lybrand L.L.P, independent certified public accountants, incorporated by reference herein, and upon the authority of said firm as experts in accounting and auditing. 26 PART II INFORMATION NOT REQUIRED IN PROSPECTUS ITEM 14. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION. The following table sets forth all expenses in connection with the issuance and distribution of the Securities being registered. All amounts except the SEC registration fee and the rating agency fees are estimates.

INDEMNIFICATION OF DIRECTORS AND OFFICERS. Article Thirteenth of the Company's Certificate of Incorporation provides for the elimination of personal monetary liabilities of directors of the Company for breaches of certain of their fiduciary duties to the full extent permitted by Section 102(b)(7) of the General Corporation Law of Delaware (the "GCL"). Section 102(b)(7) of the GCL enables a corporation in its certificate of incorporation to eliminate or limit the personal liability of members of its board of directors to the corporation or its stockholders for monetary damages for violations of a director's fiduciary duty of care. Such a provision has no effect on the availability of equitable remedies, such as an injunction or rescission, for breach of fiduciary duty. In addition, no such provision may eliminate or limit the liability of a director for breaching his duty of loyalty, failing to act in good faith, engaging in intentional misconduct or knowingly violating the law, paying an unlawful dividend or approving an illegal stock repurchase, or obtaining an improper personal benefit. Article VIII of the Company's By-Laws provides that directors and certain other personnel of the Company shall be indemnified against expenses and certain other liabilities arising out of legal actions brought or threatened against them for their conduct on behalf of the Company, subject to certain qualifications and provided that each such person acted in good faith and in a manner that such person reasonably believed was in the Company's best interest. The Company has entered into indemnification agreements with each director and certain officers of the Company and one of its subsidiaries providing that (a) the Company agrees to comply in all respects with each and every provision of Article VIII of the By-Laws in effect on the date of the agreement, (b) no amendment to Article VIII or the agreement will eliminate, reduce or affect any such directors' or officers' rights under Article VIII or the agreement with respect to indemnification, and (c) no legal action shall be brought and no cause of action shall be asserted by or on behalf of the Company against the indemnified party after the expiration of two years from the date of accrual of such cause of action. The Company maintains directors, and officers, liability insurance which insures against liabilities that directors or officers of the Company may incur in such capacities. II-1 ITEM 16.

ITEM 17. UNDERTAKINGS. The Company hereby undertakes: (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; II-2 (iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement; PROVIDED, HOWEVER, that paragraphs (1)(i) and (1)(ii) do not apply if the Registration Statement is on Form S-3 and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Company pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial BONA FIDE offering thereof. (3) To remove from registration by means of a post-effective amendment any of the Securities being registered which remain unsold at the termination of the offering. The Company hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Company's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities therein, and the offering of such securities at that time shall be deemed to be the initial BONA FIDE offering thereof. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Company pursuant to the provisions referred to an Item 15 of this Registration Statement, or otherwise, the Company has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Company of expenses incurred or paid by a director, officer or controlling person of the Company in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the Securities being registered, the Company will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue. II-3 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Portland and State of Maine, on the 12th day of July, 1996.
