S-2 3 THE COMPANIES Aetna and its subsidiaries constitute the nation's largest health benefits company, based on membership, and one of the nation's largest insurance and financial services organizations centered around three core businesses: health care, retirement services and international. Aetna's health care business, formed by the combination of Aetna Health Plans and U.S. Healthcare, Inc. ("U.S. Healthcare") has a presence in all 50 states and provides health care benefits to over 20 million people in the United States through a full spectrum of managed care, indemnity and specialty health products. Aetna's combined health business accounted for approximately 68% of the total pro forma revenues of Aetna for the year ended December 31, 1995. The combined health business offers comprehensive managed health care services through health maintenance organizations. Point of service and preferred provider organization plans are also offered. These managed care products cover over 10 million members receiving benefits through an extensive network of physicians, hospitals and pharmacies. Customers include both small employers as well as large commercial accounts; Medicare managed care plans are also offered in many areas. The combined health business also offers specialty health products including behavioral health and dental plans, and other benefit coverages including prescription drug plans, vision plans, employee assistance programs and wellness programs. The combined health business also makes available home health care and other outpatient services, network-based workers' compensation case management and disability services, quality and outcome measurement and improvement programs and health data analysis systems. Group insurance products offered by the combined health business include life insurance, disability (including managed disability) coverage and long-term care plans. Aetna Retirement Services ("ARS") is among the nation's larger life insurers, based on total assets, and markets and services life insurance and financial services products directly and through employer-sponsored retirement plans. ARS products include individual and group annuity contracts, individual and group nonqualified annuity contracts, and universal life, variable universal life, interest-sensitive whole life and term insurance. Aetna International, through subsidiaries and joint venture operations, sells primarily life insurance and financial services products in non-U.S. markets, including Canada, Mexico, Taiwan, Chile, Malaysia, Hong Kong, New Zealand, Peru, Argentina and Indonesia. Aetna International serves over 8 million customers worldwide. RECENT DEVELOPMENTS MERGERS AND DIVESTITURES On July 19, 1996, the Company and U.S. Healthcare merged into separate wholly-owned subsidiaries of Aetna (the "Mergers"). In connection with the Mergers, the Company (formerly Aetna Life and Casualty Company) changed its name to Aetna Services, Inc. The Company's merger with U.S. Healthcare represents a major step in the Company's previously announced strategic decision to focus its resources on pursuing growth opportunities in its health care business and evaluate opportunities for growth and development of its financial services and international operations. Following a comprehensive review of the Company's long-term strategic objectives and alternatives, in the fall of 1995, the Company conducted a controlled auction of its property-casualty operations. On November 28, 1995, the Company entered into an agreement with the Travelers Insurance Group Inc. for the sale of such operations (the "Property-Casualty Sale"). The Property-Casualty Sale was completed on April 2, 1996 for approximately $4.1 billion in cash. On March 30, 1996, the Company entered into an agreement to merge with U.S. Healthcare. The Company's decision to pursue a merger transaction with U.S. Healthcare was based on analysis of the information obtained regarding U.S. Healthcare and other potential transaction candidates, including management's view that U.S. Healthcare was the preferred candidate for a transaction by the Company in the S-3 4 health care sector. The Company management believed that U.S. Healthcare best met, overall, the Company's candidate selection criteria, including leadership and management capability, managed care capability, scalable information technology systems and business infrastructure, and market presence in certain geographic areas. The Company management's view was also based on U.S. Healthcare's record of profitability relative to other transaction candidates, its direct marketing capability and its position in the commercial sector of the health care business, which was viewed as complementary to the Company's position. The transaction with U.S. Healthcare was valued at over $8 billion, and was financed by the issuance of Aetna Common Stock and Aetna 6.25% Class C Voting Preferred Stock, together with $5.3 billion of cash. The cash represented $3.9 billion of the net proceeds received from the Property-Casualty Sale and funds made available by the issuance of $1.4 billion of commercial paper of the Company, which as of the effective time of the Mergers was guaranteed by Aetna. GUARANTEES On August 2, 1996, Aetna unconditionally guaranteed the payment of all principal, premium, if any, and interest on the following outstanding securities: $100,000,000 8 5/8% Notes due 1998; $200,000,000 6 3/8% Notes due 2003; $200,000,000 6 3/4% Debentures due 2013; $63,500,000 7 3/4% Eurodollar Notes due 2016; $200,000,000 8% Debentures due 2017; $200,000,000 7 1/4% Debentures due 2023; and 11,000,000 Shares of 9 1/2% Cumulative Monthly Income Preferred Securities, Series A, of Aetna Capital L.L.C. and the related $348,000,000 9 1/2% Subordinated Debentures due 2024. As a result, payments on all of the Company's outstanding debt securities and the preferred securities of a subsidiary are guaranteed by Aetna. RATINGS In July 1996, Standard & Poor's Corporation, Moody's Investors Service, Inc. and Duff & Phelps Credit Rating Company affirmed the senior debt and commercial paper ratings of the Company and removed the Company's ratings from credit watch. Standard & Poor's Corporation announced on July 16, 1996 that it had lowered the claims paying rating of Aetna Life Insurance Company, a wholly-owned subsidiary of the Company, from A+ to A and had lowered the claims paying rating of Aetna Life Insurance and Annuity Company, a wholly-owned subsidiary of the Company, from AA to AA-. USE OF PROCEEDS The Company intends to use the net proceeds from the sale of the Notes and the Debentures, estimated to be approximately $992 million, to repay outstanding commercial paper borrowings with maturities of up to 270 days from the issue date and bearing interest at a blended rate of 5.48%. See "Recent Developments." S-4 5 CAPITALIZATION The following table sets forth the actual short-term debt and capitalization of the Company as of June 30, 1996 and the pro forma short-term debt and capitalization of Aetna as of June 30, 1996, and as adjusted to give effect to the issuance of the Notes and Debentures and the application of the estimated net proceeds thereof as set forth in "Use of Proceeds."

S-5 6 UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS The following unaudited pro forma condensed consolidated statements of income of Aetna for the six months ended June 30, 1996 and the twelve months ended December 31, 1995 present results for Aetna as if each of the following had occurred as of January 1, 1996 and January 1, 1995, respectively: (i) the consummation of the Property-Casualty Sale and (ii) the consummation of the Mergers (including associated borrowings and related transactions). The accompanying unaudited pro forma condensed consolidated balance sheet for Aetna as of June 30, 1996 gives effect to the Mergers (including associated borrowings and related transactions) as if they had occurred as of June 30, 1996. The Mergers were accomplished through the merger of the Company and U.S. Healthcare into separate wholly-owned subsidiaries of Aetna (the "Aetna Sub Merger" and the "U.S. Healthcare Sub Merger," respectively). The U.S. Healthcare Sub Merger was accounted for under the purchase method of accounting. Accordingly, the amount of the consideration paid in the U.S. Healthcare Sub Merger has been allocated to assets acquired and liabilities assumed based on their estimated fair values. The excess of such consideration over the estimated fair value of such assets and liabilities has been preliminarily allocated to certain identifiable intangible assets and goodwill. The purchase price allocation may be adjusted upon completion of the final valuations of U.S. Healthcare's assets and liabilities and the effect of any such adjustment could be significant. The Aetna Sub Merger was treated as a reorganization with no change in the recorded amount of the Company's assets and liabilities. The unaudited pro forma condensed consolidated financial statements do not give effect to any synergies which may be realized as a result of the Mergers and do not give effect to the issuance of the Notes or Debentures. Additionally, the unaudited pro forma condensed consolidated financial statements do not reflect interest income earned for the period April 2, 1996 through June 30, 1996 on that portion of the cash consideration paid at closing of the U.S. Healthcare Sub Merger from the proceeds of the Property-Casualty Sale. The unaudited pro forma condensed consolidated statement of income for the six months ended June 30, 1996 includes facilities and severance charges of $392.7 million related to the Property-Casualty Sale (including actions taken or expected to be taken to reduce the level of corporate expenses and other costs previously absorbed by the property-casualty operations) and actions taken or expected to be taken primarily to reduce information technology costs in the Company's health care operations, and are not related to the Mergers. The foregoing charges were taken in the second quarter of 1996. The unaudited pro forma condensed consolidated financial statements do not reflect any nonrecurring/unusual restructuring charges that may be incurred as a result of the integration of the Company's and U.S. Healthcare's combined health operations. Aetna anticipates reflecting a significant charge in the third quarter of 1996 related to restructuring actions expected to be taken as a result of the integration of U.S. Healthcare. The amount of such charge cannot be reasonably estimated at this time. The unaudited pro forma condensed consolidated financial statements are provided for informational purposes only and do not purport to represent what Aetna's financial position or results of operations actually would have been had the Property-Casualty Sale and the Mergers in fact occurred on the dates indicated, or to project Aetna's financial position or results of operations for any future date or period. The unaudited pro forma condensed financial statements are derived from the unaudited pro forma condensed financial statements, and the notes thereto, included in the Form 8-K of Aetna filed on July 26, 1996, which is incorporated herein by reference, and should be read in conjunction herewith. The unaudited pro forma condensed consolidated financial statements are based on the historical consolidated financial statements of the Company and U.S. Healthcare and should be read in conjunction with such historical financial statements, and the notes thereto, which are included in the annual reports on Form 10-K of the Company and Form 10-K/A of U.S. Healthcare for the year ended December 31, 1995 and the quarterly reports on Form 10-Q of the Company for the quarter ended June 30, 1996 and U.S. Healthcare for the quarter ended March 31, 1996, incorporated herein by reference. The financial data of U.S. Healthcare for the six-month period ended June 30, 1996 is derived from unaudited financial statements. The unaudited financial statements include all adjustments necessary for a fair presentation of the financial position and the results of operations for such period. Operating results for the six-month period ended June 30, 1996 are not necessarily indicative of the results that may be expected for the year ended December 31, 1996.

The Notes are unsecured obligations of the Company and rank equally with all other unsecured and unsubordinated indebtedness of the Company.

Principal of and interest on the Notes will be payable at the office or agency of the Company maintained for such purposes in the City of Hartford; provided, however, that at the option of the Company, payment of interest may be made by check mailed to the address of the person entitled thereto as such address shall appear in the security register. The 2001 Notes will mature on August 15, 2001 and the 2006 Notes will mature on August 15, 2006, and the Notes will not be redeemable by the Company prior to maturity. The Notes will not have the benefit of any sinking fund. The Senior Indenture permits the defeasance of the Notes upon the satisfaction of the conditions described under "Description of Debt Securities -- Defeasance and Covenant Defeasance" in the accompanying Prospectus. The Notes may be transferred or exchanged without any service charge at the corporate trust office of the Trustee in the City of Hartford, or at any other office or agency maintained by the Company for such purpose. DEBENTURES The 2026 Debentures will be limited to $ aggregate principal amount and the 2036 Debentures will be limited to $ aggregate principal amount. The 2026 Debentures and the 2036 Debentures will each constitute a series of Senior Debt Securities of the Company, and are to be issued under the Senior Indenture as defined in the Prospectus. The Debentures are unconditionally guaranteed as to payment of principal and interest by Aetna. The Debentures are unsecured obligations and rank equally with all other unsecured and unsubordinated indebtedness of the Company. The Guarantees are unsecured obligations and rank equally with all other unsecured and unsubordinated indebtedness of Aetna. Reference is made to the Prospectus for a detailed summary of additional provisions of the Debentures and the Guarantees and of the Senior Indenture under which the Debentures and the Guarantees are issued. Capitalized terms not otherwise defined herein shall have the meanings given to them in the Prospectus and the Senior Indenture. The 2026 Debentures will bear interest at the rate of % per annum and the 2036 Debentures will bear interest at the rate of % per annum, in each case from August , 1996, or from the most recent S-12 13 interest payment date to which interest has been paid or duly provided for, payable semiannually on February 15 and August 15, commencing February 15, 1997, to the persons in whose names the Debentures are registered at the close of business on the February 1 and August 1, as the case may be, preceding such February 15 and August 15. Principal of and interest on the Debentures will be payable at the office or agency of the Company maintained for such purposes in the City of Hartford; provided, however, that at the option of the Company, payment of interest may be made by check mailed to the address of the person entitled thereto as such address shall appear in the Security Register. The 2026 Debentures will mature on August 15, 2026 and the 2036 Debentures will mature on August 15, 2036 and the Debentures will not be redeemable by the Company prior to maturity. The Debentures will not have the benefit of any sinking fund. The Indenture permits the defeasance of the Debentures upon the satisfaction of the conditions described under "Description of Debt Securities -- Defeasance and Covenant Defeasance" in the Prospectus. The Debentures may be transferred or exchanged without any service charge at the corporate trust office of the Trustee in the City of Hartford, or at any other office or agency maintained by the Company for such purpose. OPTIONAL REPAYMENT The 2036 Debentures may be repaid on August 15, 2004, at the option of the registered holders of the 2036 Debentures, at 100% of their principal amount, together with accrued interest to August 15, 2004. In order for a holder to exercise this option, the Company must receive at its office or agency in Hartford, Connecticut, during the period beginning on June 15, 2004 and ending at 5:00 p.m. (Hartford, Connecticut time) on July 15, 2004 (or, if July 15, 2004 is not a Business Day, the next succeeding Business Day), the certificate representing the 2036 Debenture subject to repayment with the form "Option to Elect Repayment on August 15, 2004" on such certificate duly completed. Any such notice received by the Company during the period beginning on June 15, 2004 and ending at 5:00 p.m. (Hartford, Connecticut time) on July 15, 2004 shall be irrevocable. See "-- Book Entry, Delivery and Form." The repayment option may be exercised by the holder of a 2036 Debenture for less than the entire principal amount of the 2036 Debentures held by each such holder, so long as the principal amount that is to be repaid is equal to $1,000 or an integral multiple of $1,000. All questions as to the validity, form, eligibility (including time of receipt) and acceptance of any 2036 Debenture for repayment will be determined by the Company, whose determination will be final and binding. Failure by the Company to repay the 2036 Debentures when required as described in the preceding paragraph will result in an Event of Default under the Indenture. As long as the 2036 Debentures are represented by a Global Debenture (as defined below), the Depositary or the Depositary's nominee will be the registered holder of the 2036 Debentures and theretofore will be the only entity that can exercise a right to repayment. See "-- Book Entry, Delivery and Form." No similar right of repayment is available to holders of the 2001 Notes, the 2006 Notes or the 2026 Debentures. BOOK-ENTRY, DELIVERY AND FORM The Notes and the Debentures will each be issued in the form of one or more fully registered certificates registered in the name of Cede & Co., the nominee of The Depository Trust Company (the "Depository"). Except as provided below, owners of beneficial interests in the certificates for the Notes registered in the name of the Depository ("Global Notes") or in the certificates for the Debentures registered in the name of the Depository ("Global Debentures") will not be entitled to have either the Global Notes or the Global Debentures, as the case may be, registered in their names and will not receive or be entitled to receive physical delivery of either the Global Notes or the Global Debentures in definitive form. Unless and until definitive Notes or Debentures are issued to owners of beneficial interests in the Global Notes or the Global Debentures, such owners of beneficial interests will not be recognized as Holders of either the Notes or the Debentures, as the case may be, by the Trustee. Hence, until such time, owners of beneficial interests in either the Global S-13 14 Notes or the Global Debentures will only be able to exercise the rights of Holders indirectly through the Depository and its participating organizations. Except as set forth below, the certificates may not be transferred except as a whole by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of the Depository or by the Depository or any nominee to a successor of the Depository or a nominee of such successor. The Depository has advised the Company and Aetna that it is a limited-purpose trust Company organized under the laws of the State of New York, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the Uniform Commercial Code and a "clearing agency" registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended. The Depository was created to hold securities for its participants and to facilitate the clearance and settlement of securities transactions among its participants in such securities through electronic book-entry changes in accounts of the participants, thereby eliminating the need for physical movement of securities certificates. The Depository's participants include securities brokers and dealers (including the Underwriters), banks, trust companies, clearing corporations and certain other organizations, some of which (and/or their representatives) own the Depository. Access to the Depository's book-entry system is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly. Persons who are not participants may beneficially own securities held by the Depository only through participants. The Depository advises that pursuant to procedures established by it (i) upon the issuance of the Notes and the Debentures by the Company, the Depository will credit the accounts of participants designated by the Underwriters with the amount of the Global Notes and the Global Debentures purchased by the Underwriters, and (ii) ownership of beneficial interests in the certificates representing the Global Notes and the Global Debentures will be shown on, and the transfer of that ownership will be effected only through, records maintained by the Depository (with respect to participants' interests) and the participants and the indirect participants (with respect to beneficial owners' interests). The laws of some states require that certain persons take physical delivery in definitive form of securities which they own. Consequently, the ability to transfer beneficial interests in such certificates is limited to such extent. Neither the Company, Aetna, the Trustee, any Payment Agent, nor the Security Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the certificates representing the Global Notes or the Global Debentures or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. Principal and interest payments on the Global Notes and the Global Debentures registered in the name of the Depository's nominee will be made by the Trustee to the Depository's nominee as the registered owner of the certificates relating to the Global Notes and the Global Debentures. The Senior Indenture provides that the Company, Aetna and the Trustee will treat the persons in whose names either the Global Notes or the Global Debentures are registered (the Depository or its nominee) as the owners of the Global Notes or the Global Debentures, as the case may be, for the purpose of receiving payment of principal and interest on either the Global Notes or the Global Debentures and for all other purposes whatsoever. Therefore, neither the Company, Aetna, the Trustee nor any Paying Agent has any direct responsibility or liability for the payment of principal or interest on the Global Notes or the Global Debentures to owners of beneficial interests in the certificates relating to the Global Notes or the Global Debentures. The Depository has advised the Company, Aetna and the Trustee that its present practice is, upon receipt of any payment of principal or interest, to immediately credit the accounts of the participants with such payment in amounts proportionate to their respective holdings in principal amount of beneficial interests in the certificates relating to the Global Notes or the Global Debentures, as shown on the records of the Depository. Payments by participants and indirect participants to owners of beneficial interests in the certificates relating to the Global Notes and the Global Debentures will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in "street name", and will be the responsibility of the participants or indirect participants. S-14 15 If the Depository is at any time unwilling or unable to continue as depository and a successor depository is not appointed by the Company, the Company will issue Notes and Debentures in definitive form, having the guarantee of Aetna endorsed thereon, in exchange for the total amount of the certificates representing the Global Notes and the Global Debentures. In addition, the Company may at any time determine not to have Notes or Debentures represented by Global Notes or Global Debentures, as the case may be, and, in such event, the Company will issue Notes or Debentures in definitive form, having the guarantee of Aetna endorsed thereon, in exchange for the total amount of the certificates representing the Global Notes or the Global Debentures. In addition, if any event shall have happened and be continuing that constitutes an Event of Default with respect to the Notes or the Debentures, the owners of beneficial interests in certificates for the Global Notes or the Global Debentures will be entitled to receive Notes or Debentures, as the case may be, in certificated form in exchange for the Book-Entry certificate or certificates representing the Global Notes or the Global Debentures, as the case may be. In any such instance, an owner of a beneficial interest in such certificates will be entitled to physical delivery in definitive form of Notes or Debentures equal in amount to such beneficial interest and to have such Notes or Debentures registered in its name. S-15 16 UNDERWRITING Subject to the terms and conditions set forth in an underwriting agreement (the "Underwriting Agreement") among the Company, Aetna, and Merrill Lynch, Pierce Fenner & Smith Incorporated, CS First Boston Corporation, Donaldson Lufkin & Jenrette Securities Corporation, Goldman, Sachs & Co., Lehman Brothers Inc., J.P.

The Underwriters may allow, and such dealers may reallow, a discount not in excess of % of the principal amount of the 2001 Notes, % of the principal amount of the 2006 Notes, and % of the principal amount of the 2026 Debentures and % of the principal amount of the 2036 Debentures to other brokers and dealers. After the initial public offering, the offering price, concession and discount may be changed. The Notes and Debentures are new issues of securities with no established trading market. The Company and Aetna have been advised by the Underwriters that they intend to make a market in the Notes and Debentures but are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of the trading market for the Notes or Debentures. The Underwriters from time to time each provide investment banking services to the Company and Aetna. The Company and Aetna have agreed to indemnify the several Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended and other applicable securities laws, or to contribute to payments the Underwriters may be required to make in respect thereof.

AHP consists of Health, Specialty Health and Group Insurance businesses. The Health business provides a full spectrum of managed care and traditional indemnity plans, providing its members with a choice of health plans to meet their individual needs. AHP's managed care products vary with respect to the extent to which health care costs and utilization are managed and range from preferred provider organization plans to point-of-service and health maintenance organization plans. The Company also owns and manages physician practices for use by its members and other consumers. Specialty Health products include behavioral health, pharmacy and dental plans, which provide managed care or indemnity features. The Group Insurance business provides life insurance, disability (including managed disability) and long-term care plans. AHP products and services are marketed primarily to employers for the benefit of employees and their dependents. Plans may be insured, whereby the Company assumes all or a portion of health care cost and utilization risk, or self-funded, whereby employers assume all or a significant portion of such risks. AHP also provides administrative and claim services and, in many cases, partial insurance protection, for an appropriate fee or premium charge. ARS markets and services two principal types of products: financial services and life insurance. The financial services products include individual and group annuity contracts which offer a variety of funding and distribution options for personal and employer-sponsored retirement plans that qualify under Sections 401, 403, 408 and 457 of the Internal Revenue Code of 1986, as amended, and individual and group nonqualified annuity contracts. ARS's life insurance products include universal life, variable universal life, interest-sensitive whole life and term insurance. These products are offered primarily to individuals, small businesses, employer-sponsored groups and executives of Fortune 2000 companies. Aetna International, through subsidiaries and joint venture operations, sells primarily life insurance and financial services products in non-U.S. markets including Canada, Mexico, Taiwan, Chile, Malaysia, Hong Kong, New Zealand, Peru, Argentina and Indonesia. On April 2, 1996, the Company completed the previously announced sale of its property-casualty operations to an affiliate of The Travelers Insurance Group Inc. ("Travelers") for total consideration of approximately $4.1 billion. 3 20 In connection with the approval by shareholders of the Company of the proposed merger of the Company and U.S. Healthcare pursuant to which each of the Company and U.S. Healthcare will become wholly-owned subsidiaries of Aetna, the shareholders of the Company will also be asked to approve an amendment to the Company's Certificate of Incorporation to change its name to Aetna Services, Inc. See "Aetna Inc." below. The principal executive offices of the Company are located at 151 Farmington Avenue, Hartford, CT 06156. The Company's telephone number is (860) 273-0123. 4 21 AETNA INC. Aetna Inc., a Connecticut corporation, was formed by the Company and U.S. Healthcare in March 1996 in connection with the Agreement and Plan of Merger, dated as of March 30, 1996, as amended by Amendment No. 1 thereto dated as of May 30, 1996 (the "Merger Agreement"), among the Company, U.S. Healthcare, Aetna, Antelope Sub, Inc., a Connecticut corporation and a wholly-owned subsidiary of Aetna ("Aetna Sub"), and New Merger Corporation, a Pennsylvania corporation and a wholly-owned subsidiary of Aetna ("U.S. Healthcare Sub"). Pursuant to such Merger Agreement and subject to the conditions contained therein, including the approval of the Merger Agreement by the shareholders of the Company and U.S. Healthcare at shareholder meetings to be held on July 18, 1996, Aetna Sub will be merged with and into the Company (the "Aetna Sub Merger") and U.S. Healthcare Sub will be merged with and into U.S. Healthcare (the "U.S. Healthcare Sub Merger" and, together with the Aetna Sub Merger, the "Mergers"), with the result that the Company and U.S. Healthcare will become wholly-owned subsidiaries of Aetna. Accordingly, the businesses of Aetna through its wholly-owned subsidiaries, the Company and U.S. Healthcare, initially will be the businesses currently conducted by the Company and U.S. Healthcare and their respective subsidiaries. The U.S. Healthcare Sub Merger will be accounted for under the purchase method of accounting and the Aetna Sub Merger will be treated as a reorganization with no change in the recorded amount of the Company's assets and liabilities. If approved by the shareholders of the Company and U.S. Healthcare at such meetings and if the other conditions to the Mergers set forth in the Merger Agreement are satisfied, it is currently expected that the Mergers will be consummated in the third quarter of 1996. Aetna has not conducted any business activities to date, other than those incident to its formation, its execution of the Merger Agreement and related agreements and in connection with the Mergers. The principal executive offices of Aetna are located at 151 Farmington Avenue, Hartford, Connecticut 06156; its telephone number is (860) 273-0123. U.S. HEALTHCARE, INC. U.S. Healthcare is a Pennsylvania corporation, incorporated in 1982. U.S. Healthcare is one of the largest managed care companies in the United States. As of December 31, 1995, U.S. Healthcare's health maintenance organization ("HMO") service network included approximately 13,400 primary care physicians, 40,600 specialists, 441 hospitals and 7,000 pharmacies. U.S. Healthcare provides comprehensive managed health care services through HMOs it owns and operates in Pennsylvania, New Jersey, New York, Delaware, Connecticut, Massachusetts, New Hampshire, Maryland, Georgia, Virginia, Rhode Island, North Carolina, South Carolina, Ohio and the District of Columbia. The services of U.S. Healthcare's HMOs are marketed primarily to employer groups and are provided through networks of independent health care providers, including selected primary care physicians who coordinate each member's individual medical care. In addition to comprehensive primary physician care, specialist care and hospital services, U.S. Healthcare makes available home health care and other outpatient services as well as optional prescription drug, vision care and dental plans. U.S. Healthcare contracts with independent primary care physicians who are reimbursed under prospective payment arrangements. U.S. Healthcare's health plans consist of HMO plans and indemnity-type plans offered both on a fully-insured and an employer-funded basis. Under fully-insured health plans, U.S. Healthcare charges a premium and bears the risk for medical costs incurred. Under employer-funded health plans, U.S. Healthcare charges a fee for providing administrative services and the employer bears substantially all risk for medical costs incurred. Under fully-insured HMO plans, members receive comprehensive medical coverage in exchange for a fixed monthly premium. In addition, U.S. Healthcare also offers a number of supplemental benefit coverages to employers, either as supplements to HMO plans or as stand-alone products, including dental plans, prescription drug plans, vision plans, employee assistance programs and wellness programs. U.S. Healthcare offers network-based workers' compensation case management and network-based managed disability services, quality and outcome measurement and improvement programs and health care data analysis systems for providers and purchasers of health care. U.S. Healthcare provides assistance to multi-state employers by coordinating their relationships with other HMOs. 5 22 USE OF PROCEEDS Except as may otherwise be set forth in the applicable Prospectus Supplement, the net proceeds from the sale of the Debt Securities will be added to the Company's general funds and used for general corporate purposes, including the repayment of indebtedness. RATIO OF EARNINGS TO FIXED CHARGES OF THE COMPANY The following table sets forth the Company's historical ratio of earnings to fixed charges for the periods indicated. THREE MONTHS YEARS ENDED DECEMBER 31, ENDED ------------------------------------------ MARCH 31, 1996 1995 1994 1993 1992 1991 - -------------- ---- ---- ---- ---- ------ 6.04 4.97 4.74 (a) 1.90 .54(b) - --------------- (a) The Company reported a pretax loss from continuing operations in 1993 which was inadequate to cover fixed charges by $1.0 billion. (b) Earnings were inadequate to cover fixed charges by $92.0 million in 1991. For purposes of computing the ratio of earnings to fixed charges, "earnings" represent consolidated earnings from continuing operations before income taxes, cumulative effect adjustments and extraordinary items plus fixed charges and minority interests. "Fixed charges" consist of interest (and the portion of rental expense deemed representative of the interest factor). The Company's former property-casualty operations, sold to Travelers on April 2, 1996 and certain other operations are reflected as discontinued operations in its consolidated financial statements. 6 23 DESCRIPTION OF DEBT SECURITIES AND DEBT GUARANTEES The following description sets forth certain general terms and provisions of the Debt Securities and Debt Guarantees to which any Prospectus Supplement may relate. The particular terms of the Debt Securities and Debt Guarantees offered by any Prospectus Supplement and the extent, if any, to which such general provisions may not apply to the Debt Securities and Debt Guarantees so offered will be described in the Prospectus Supplement relating to such Debt Securities and Debt Guarantees. The Senior Debt Securities and the Senior Debt Guarantees are to be issued under an Indenture to be dated as of July 1, 1996 (the "Senior Indenture"), between the Company, Aetna and State Street Bank and Trust Company of Connecticut, National Association, as trustee. The Subordinated Debt Securities and the Subordinated Debt Guarantees are to be issued under a separate Indenture to be dated as of July 1, 1996 (the "Subordinated Indenture"), also between the Company, Aetna and State Street Bank and Trust Company of Connecticut, National Association, 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 have been filed as exhibits to the Registration Statement. State Street Bank and Trust Company of Connecticut, National Association is hereinafter referred to as the "Trustee." The following summaries of certain provisions of the Senior Debt Securities, the Subordinated Debt Securities, the Senior Debt Guarantees, the Subordinated Debt Guarantees 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 and the related Debt Guarantees, including the definitions therein of certain terms. Wherever particular Sections, Articles or defined terms of the Indentures are referred to, it is intended that such Sections, Articles or defined terms shall be incorporated herein by reference. Article and Section references used herein are references to the applicable Indenture. 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. Unless otherwise specified in the Prospectus Supplement, the Senior Debt Securities and the Senior Debt Guarantees when issued will be unsecured and unsubordinated obligations of the Company and Aetna, respectively, and will rank equally and ratably with all other unsecured and unsubordinated indebtedness of the Company and Aetna, respectively. The Subordinated Debt Securities and the Subordinated Debt Guarantees when issued will be unsecured and subordinated in right of payment to the prior payment in full of all Senior Debt (as defined) of the Company and Aetna, respectively, as described under "Subordination of Subordinated Debt Securities and Subordinated Debt Guarantees" and in the Prospectus Supplement applicable to an offering of Subordinated Debt Securities and the Subordinated Debt Guarantees. Reference is made to the Prospectus Supplement relating to the particular Debt Securities offered thereby (the "Offered Debt Securities") which shall set forth whether the Offered Debt Securities shall be Senior Debt Securities, guaranteed on a senior basis by Aetna pursuant to the Senior Debt Guarantees, or Subordinated Debt Securities, guaranteed on a subordinated basis by Aetna pursuant to the Subordinated Debt Guarantees, and shall further set forth the following terms of the Offered Debt Securities: (1) the title of the Offered Debt Securities;

(4) the date or dates on which the principal of the Offered Debt Securities will be payable; (5) the rate or rates per annum (which may be fixed, floating or adjustable) at which the Offered Debt Securities will bear interest, if any, or the formula pursuant to which such rate or rates shall be determined, the date or dates from which such interest will accrue and the dates on which such interest, if any, will be payable and the Regular Record Dates for such interest payment dates; (6) whether the Offered Debt Securities will be secured; (7) the place or places where principal of (and premium, if any) and interest, if any, on Offered Debt Securities will be payable; (8) if applicable, the price at which, the periods within which and the terms and conditions upon which the Offered Debt Securities may be redeemed at the option of the Company pursuant to a sinking fund or otherwise; (9) if 7 24 applicable, any obligation of the Company to redeem or purchase Offered Debt Securities pursuant to any sinking fund or analogous provisions or at the option of a Holder thereof, and the period or periods within which, the price or prices at which and the terms and conditions upon which the Offered Debt Securities will be redeemed or purchased, in whole or in part; (10) if other than denominations of $1,000 and any integral multiple thereof, the denominations in which the Offered Debt Securities will be issuable; (11) the currency or currencies, including composite currencies or currency units, in which payment of the principal of (or premium, if any) or interest, if any, on any of the Offered Debt Securities will be payable if other than the currency of the United States of America; (12) if the amount of payments of principal of (or premium, if any) or interest, if any, on the Offered Debt Securities may be determined with reference to one or more indices, the manner in which such amounts will be determined; (13) if the principal of (or premium, if any) or interest, if any, on any of the Offered Debt Securities of the series is to be payable, at the election of the Company or a Holder thereof, in one or more currencies, including composite currencies, or currency units other than that or those in which the Debt Securities are stated to be payable, the currency, currencies, including composite currencies, or currency units in which payment of the principal of (or premium, if any) or interest, if any, on Debt Securities of such series as to which such election is made will be payable, and the periods within which and the terms and conditions upon which such election is to be made; (14) the portion of the principal amount of the Offered Debt Securities, if other than the principal amount thereof, payable upon acceleration of maturity thereof; (15) whether all or any part of the Offered Debt Securities will be issued in the form of a Global Security or Securities and, if so, the depositary for, and other terms relating to, such Global Security or Securities; (16) any event or events of default applicable with respect to the Offered Debt Securities in addition to those provided in the Indentures; (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 Indentures 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 Indentures 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; (18) the guarantee of Aetna of the Debt Securities if other than as described herein; (19) any restriction or condition on the transferability of the Offered Debt Securities; (20) any authenticating or paying agents, registrars, conversion agents or any other agents with respect to the Offered Debt Securities;

(Section 301) Unless otherwise indicated in the Prospectus Supplement relating thereto, the Offered Debt Securities are to be issued as registered securities without coupons in denominations of $1,000 or any integral multiple of $1,000. (Section 302) No service charge will be made for any transfer or exchange of such Offered Debt Securities, but the Company or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. (Section 305) Debt Securities may be issued under the Indentures as Original Issue Discount Securities to be sold at a substantial discount below their stated principal amount. Federal income tax consequences and other considerations applicable thereto will be described in the Prospectus Supplement relating hereto. Since the Company is, and following the Mergers Aetna will be, a holding company, the rights of the Company and Aetna, respectively, and hence the right of creditors of the Company and Aetna (including the Holders of Debt Securities), to participate in any distribution of the assets of their respective subsidiaries (including in the case of Aetna following the Mergers, the Company and U.S. Healthcare), upon any such Subsidiary's 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 or Aetna, as a creditor of the subsidiary, may be recognized. The Indentures do not contain any provisions that limit the ability of the Company or Aetna to incur indebtedness or that afford Holders of the Debt Securities protection in the event of a highly leveraged or similar transaction involving the Company or Aetna. 8 25 EVENTS OF DEFAULT AND NOTICE THEREOF Unless otherwise specified in the Prospectus Supplement, the following events are defined in the Indentures as "Events of Default" with respect to Debt Securities of any series: (a) failure to pay principal (including any sinking fund payment) of, or premium (if any) on, any Debt Security of that series when due (in the case of the Subordinated Indenture, whether or not payment is prohibited by the subordination provisions); (b) failure to pay interest, if any, on any Debt Security of that series when due and such failure continues for a period of 30 days; (c) failure by the Company or Aetna to perform in any material respect any other covenant in the Indentures (other than a covenant included in the Indentures solely for the benefit of a series of Debt Securities other than that series) continued for a period of 90 days after written notice to the Company and Aetna; (d) due acceleration (which acceleration shall not have been rescinded within 30 days after written notice to the Company and Aetna) of any indebtedness for borrowed money in a principal amount in excess of $50,000,000 for which the Company, Aetna or a Principal Subsidiary (as defined) is liable, including Debt Securities of another series (other than acceleration of Non-Recourse Debt for borrowed money which does not exceed in the aggregate 4% of Aetna's total shareholders' equity, as set forth in the most recently published audited consolidated balance sheet of Aetna), or a default by the Company, Aetna or any Principal Subsidiary in the payment at final maturity of outstanding indebtedness for borrowed money in a principal amount in excess of $50,000,000 (other than default in payment at final maturity of Non-Recourse Debt which does not exceed in the aggregate 4% of Aetna's total shareholders' equity, as set forth in the most recently published audited consolidated balance sheet of Aetna) unless such acceleration or default at maturity shall be remedied or cured by the Company, Aetna or such Principal Subsidiary or rescinded, annulled or waived by the holders of such indebtedness, in which case such acceleration or default at maturity shall not constitute an Event of Default under this provision and any acceleration relating thereto shall be rescinded; and (e) certain events of insolvency, reorganization, receivership or liquidation of the Company or Aetna. (Section 501) No Event of Default with respect to Debt Securities of a particular series shall necessarily constitute an Event of Default with respect to Debt Securities of any other series. If an Event of Default with respect to Debt Securities of any series at the time Outstanding shall occur and be continuing, either the Trustee or the Holders of at least 25% in principal amount of the Outstanding Debt Securities of that series may declare the principal amount (or, if the Debt Securities of that series are Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series) of all Debt Securities of that series to be due and payable immediately; provided, however, that under certain circumstances the Holders of a majority in aggregate principal amount of Outstanding Debt Securities of that series may rescind or annul such declaration and its consequences. (Section 502) Reference is made to the Prospectus Supplement relating to any series of Offered Debt Securities which are Original Issue Discount Securities for the particular provisions relating to the principal amount of such Original Issue Discount Securities due on acceleration upon the occurrence of an Event of Default and the continuation thereof. The Indentures provide that the Trustee may withhold notice to the Holders of the Debt Securities of any default (except in payment of principal (or premium, if any) or interest, if any) if it considers it in the interest of the holders of the Debt Securities to do so. (Section 602) The Company and Aetna will be required to furnish to the Trustee annually a statement by certain officers of the Company and Aetna as to the compliance with all conditions and covenants of the Indentures. (Section 1004) The Holders of a majority in principal amount of the Outstanding Debt Securities of any series affected will have the right, subject to certain limitations, to 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 the Debt Securities of such series, and to waive certain defaults. (Sections 512 and 513) The Indentures provide that, in case an Event of Default shall occur and be continuing, the Trustee shall exercise such of its rights and powers under the Indentures, and use the same degree of care and skill in its 9 26 exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. (Section 601) Subject to such provisions, the Trustee will be under no obligation to exercise any of its rights or powers under the Indentures at the request of any of the Holders of Debt Securities unless they shall have offered to the Trustee security or indemnity in form and substance reasonably satisfactory to the Trustee against the costs, expenses and liabilities which might be incurred by it in compliance with such request. (Section 603) No Holder of a Debt Security of any series will have any right to institute any proceeding with respect to the Indentures or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to the Debt Securities of such series and unless also the Holders of at least 25% in aggregate principal amount of the Outstanding Debt Securities of the same series shall have made written request, and offered indemnity to the Trustee in form and substance reasonably satisfactory to the Trustee, to institute such proceeding as trustee, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of the Outstanding Debt Securities of the same series a direction inconsistent with such request and shall have failed to institute such proceeding within 60 days. (Section 507) However, such limitations do not apply to a suit instituted by a Holder of a Debt Security for enforcement of payment of the principal of (or premium, if any) or interest, if any, on such Debt Security on or after the respective due dates expressed in such Debt Security. (Section 508) MODIFICATION AND WAIVER Modifications and amendments of the Indentures may be made by the Company, Aetna and the Trustee, with the consent of the Holders of not less than a majority of aggregate principal amount of each series of the Outstanding Debt Securities issued under the Indentures which is affected by the modification or amendment; provided, however, that no such modification or amendment may, without the consent of each Holder of such Debt Security affected thereby: (1) change the Stated Maturity of the principal of (or premium, if any) or any installment of principal or interest, if any, on any such Debt Security; (2) reduce the principal amount of (or premium, if any) or the interest rate, if any, on any such Debt Security or the principal amount due upon acceleration of an Original Issue Discount Security; (3) change the place or currency of payment of principal of (or premium, if any) or the interest, if any, on any such Debt Security; (4) impair the right to institute suit for the enforcement of any such payment on or with respect to any such Debt Security; (5) reduce the percentage of Holders of Debt Securities necessary to modify or amend the Indentures; (6) modify or affect in any manner adverse to the interest of Holders of Debt Securities the obligation of Aetna under the Debt Guarantees in respect of the due and punctual payment of the principal of (and premium, if any) or interest on the Debt Securities, (7) in the case of the Subordinated Indenture, modify the subordination provisions in a manner adverse to the holders of the Subordinated Debt Securities; or (8) modify the foregoing requirements or reduce the percentage of Outstanding Debt Securities necessary to waive compliance with certain provisions of the Indentures or for waiver of certain defaults. (Section 902) The holders of at least a majority of the aggregate principal amount of the Outstanding Debt Securities of any series may, on behalf of all Holders of that series, waive compliance by the Company and Aetna with certain restrictive provisions of the Indentures and waive any past default under the Indentures, except a default in the payment of principal, premium or interest or in the performance of certain covenants. (Sections 907 and 513) DEFEASANCE AND COVENANT DEFEASANCE The Indentures provide that the Company and Aetna, at the Company's option, (A) will be defeased and discharged from any and all of their respective obligations with respect to such Debt Securities and the Debt Guarantees (including, in the case of Subordinated Debt Securities and Subordinated Debt Guarantees, the provisions described under "Subordination of Subordinated Debt Securities and Subordinated Debt Guarantees" herein and except for the obligations to exchange or register the transfer 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 monies for payments in trust) ("defeasance"), or (B) will be released from their respective obligations under the Indentures concerning the restrictions described under 10 27 "Limitations on Liens on Common Stock of Principal Subsidiaries" and "Consolidation, Merger and Sale of Assets" and any other covenants applicable to such Debt Securities and the Debt Guarantees (including, in the case of the Subordinated Debt Securities and the Subordinated Debt Guarantees, the provisions described under "Subordination of Subordinated Debt Securities and Subordinated Debt Guarantees" herein) which are subject to covenant defeasance ("covenant defeasance"), and the occurrence of an event described and notice thereof in clauses (c) and (d) under "Events of Default and Notice Thereof" (with respect to covenants subject to covenant defeasance) shall no longer be an Event of Default, in each case, upon the irrevocable deposit with the Trustee (or other qualifying trustee), in trust for such purpose, of money, and/or U.S. Government Obligations (as defined) (or Foreign Government Obligations (as defined) in the case of Debt Securities denominated in foreign currencies) which through the payment of principal and interest in accordance with their terms will provide money in an amount sufficient to pay the principal of (and premium, if any) and interest, if any, on such Debt Securities, and any mandatory sinking fund or analogous payments thereon, on the scheduled due dates therefor. Such a trust may only be established if, among other things, (i) the Company has delivered to the Trustee an opinion of counsel (as specified in the Indentures) to the effect that the Holders of such Debt Securities will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance or covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such defeasance or covenant defeasance had not occurred, (ii) no Event of Default or event which with the giving of notice or lapse of time, or both, would become an Event of Default under the Indenture shall have occurred and be continuing on the date of such deposit (or, with respect to any event specified in clause (e) under "Events of Default and Notice Thereof", at any time on or prior to the 90th day after the date of such deposit) and (iii) in the case of Subordinated Debt Securities, (x) no default in the payment of principal of (or premium, if any) or interest, if any, on any Senior Debt of the Company or Aetna beyond any applicable grace period shall have occurred and be continuing, or (y) no other default with respect to any Senior Debt of the Company or Aetna shall have occurred and be continuing and shall have resulted in the acceleration of such Senior Debt. (Article Twelve) The Company may exercise its defeasance option with respect to such Debt Securities and Debt Guarantees notwithstanding its prior exercise of its covenant defeasance option. If the Company exercises its 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 by reference to the covenants noted under clause (B) above. In the event the Company and Aetna omit to comply with their remaining obligations with respect to such Debt Securities and Debt Guarantees under the Indentures after the exercise by the Company of its covenant defeasance option and such Debt Securities are declared due and payable because of the occurrence of any Event of Default, the amount of money and U.S. Government Obligations (or Foreign Government Obligations in the case of Debt Securities denominated in foreign currencies) on deposit with the Trustee may be insufficient to pay amounts due on the Debt Securities of such series at the time of the acceleration resulting from such Event of Default. However, the Company and Aetna will remain liable in respect of such payments. (Article Twelve) LIMITATIONS ON LIENS ON COMMON STOCK OF PRINCIPAL SUBSIDIARIES As long as any of the Debt Securities remains outstanding, Aetna will not, and will not permit any Principal Subsidiary to, issue, assume, incur or guarantee any indebtedness for borrowed money secured by a mortgage, pledge, lien or other encumbrance, directly or indirectly, on any of the Common Stock of a Principal Subsidiary, which Common Stock is owned by Aetna, by the Company or by any Principal Subsidiary, unless the obligations of the Company under the Debt Securities and, if the Company or Aetna so elects, any other indebtedness of the Company or Aetna ranking on a parity with, or prior to, the Debt Securities or the Guarantor's obligations under the Debt Guarantees, as the case may be, shall be secured equally and ratably with, or prior to, such secured indebtedness for borrowed money so long as it is outstanding and is so secured. (Section 1005) "Principal Subsidiary" means only Aetna Life Insurance Company, Aetna Life Insurance and Annuity Company and U.S. Healthcare and any other Subsidiary of Aetna which shall hereafter succeed by merger or 11 28 otherwise to a major part of the business of one or more of the Principal Subsidiaries. The decision as to whether a Subsidiary shall have succeeded to a major part of the business of one or more of the Principal Subsidiaries shall be made in good faith by the Board of Directors of Aetna or a committee thereof by the adoption of a resolution so stating, and Aetna shall within 30 days of the date of the adoption of such resolution deliver to the Trustee a copy thereof, certified by the Corporate Secretary or an Assistant Corporate Secretary of Aetna. (Section 101) "Common Stock" means, with respect to any Principal Subsidiary, stock of any class, however designated, except stock which is non-participating beyond fixed dividend and liquidation preferences and the holders of which have either no voting rights or limited voting rights entitling them, only in the case of certain contingencies, to elect less than a majority of the directors (or persons performing similar functions) of such Principal Subsidiary, and shall include securities of any class, however designated, which are convertible into such Common Stock. (Section 101) CONSOLIDATION, MERGER AND SALE OF ASSETS; ASSUMPTION BY GUARANTOR OR SUBSIDIARY OF COMPANY OBLIGATIONS Neither the Company nor Aetna may consolidate with or merge into any other Person or sell its property and assets as, or substantially as, an entirety to any Person and neither the Company nor Aetna may permit any Person to merge into or consolidate with the Company or Aetna, as the case may be, unless (i) either the Company or Aetna, as the case may be, will be the resulting or surviving entity or any successor or purchaser is a corporation, partnership or trust organized under the laws of the United States of America, any State or the District of Columbia, and any such successor or purchaser expressly assumes the Company's or Aetna's obligations on the Debt Securities or the Debt Guarantees, as applicable, under a supplemental Indenture, (ii) immediately after giving effect to the transaction no Event of Default shall have occurred and be continuing, and (iii) certain other conditions are met. (Section 801) Aetna or any Subsidiary of Aetna may, where permitted by law, assume the obligations of the Company for the due and punctual payment of the principal of (premium, if any) and interest on and any other payments with respect to the Debt Securities of any series and the performance of every covenant of the Indenture and the Debt Securities on the part of Company to be performed or observed if (i) Aetna or such Subsidiary, as the case may be, shall expressly assume such obligations by a supplemental indenture, in form reasonably satisfactory to the Trustee, and, if such Subsidiary assumed such obligations, Aetna shall, by such supplemental indenture, confirm that its Debt Guarantees with respect to the Debt Securities of such series shall apply to such Subsidiary's obligations under the Debt Securities of such series and the Indenture; (ii) immediately after giving effect to such transaction, no Event of Default shall have occurred and be continuing; and (iii) certain other conditions are met. (Section 803). SUBORDINATION OF SUBORDINATED DEBT SECURITIES AND SUBORDINATED DEBT GUARANTEES Unless otherwise indicated in the Prospectus Supplement, the following provisions will apply to the Subordinated Debt Securities and Subordinated Debt Guarantees.

In the event of the acceleration of the maturity of any Subordinated Debt Securities, the holders of all Senior Debt of the Company and Aetna 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 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. (Subordinated Indenture Sections 1403 and 1603) 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 the payment of principal of (or premium, if any) or interest on Senior Debt of the Company or Aetna, or an event of default with respect to any Senior Debt of the Company or Aetna resulting in the acceleration of the maturity thereof, or if any judicial proceeding shall be pending with respect to any such default.

The accountants are not subject to the liability provisions of Section 11 of the Securities Act for any report on the unaudited interim financial information because that report is not a "report" or a "part" of the Registration Statement prepared or certified by the accountants within the meaning of Sections 7 and 11 of the Securities Act.
