DONALDSON, LUFKIN & JENRETTE
  SECURITIES CORPORATION
CONNING & COMPANY
  As representatives of the
         several underwriters
         named in Schedule I hereto
         c/o Donaldson, Lufkin & Jenrette
                   Securities Corporation
             277 Park Avenue
             New York, New York 10172

Dear Sirs:

                  Aetna Life and Casualty Company ("Aetna"), a Connecticut
insurance corporation and a stockholder of Executive Risk Inc., a Delaware
corporation (the "Company") proposes to sell an aggregate of 2,000,000 shares of
common stock, par value $.01 per share (the "Common Stock"), of the Company (the
"Firm Shares"), to the several underwriters named in Schedule I hereto (the
"Underwriters"). The Company proposes to issue and sell to the several
Underwriters not more than 300,000 additional shares of Common Stock of the
Company (the "Additional Shares"), if requested by the Underwriters as provided
in Section 2 hereof. The Firm Shares and the Additional Shares are herein
collectively called the "Shares". The Company and Aetna are sometimes
hereinafter collectively referred to as the "Sellers."





   2



         Donaldson, Lufkin & Jenrette Securities Corporation ("DLJ") and Conning
& Company shall act as representatives (the "Representatives") of the several
Underwriters.

         1. Registration Statement and Prospectus. The Company has prepared and
filed with the Securities and Exchange Commission (the "Commission"), in
accordance with the provisions of the Securities Act of 1933, as amended, and
the rules and regulations of the Commission thereunder (collectively, the
"Act"), a registration statement on Form S-3 (Registration No. 333-3956)
including a prospectus relating to the Shares, which registration statement may
be amended. The registration statement, as amended at the time when it becomes
effective, including any amendment to the registration statement filed pursuant
to Rule 462(b) under the Act increasing the size of the offering registered
under the Act and information (if any) deemed to be part of the registration
statement at the time of effectiveness pursuant to Rule 430A (or Rule 434) under
the Act (and including, in each case, all documents incorporated by reference),
is hereinafter referred to as the "Registration Statement;" and the prospectus
in the form first used to confirm sales of Shares is hereinafter referred as the
"Prospectus."

         2. Agreements to Sell and Purchase. Upon the basis of the
representations and warranties contained in this Agreement, and subject to its
terms and conditions, Aetna hereby agrees to sell to the Underwriters the Firm
Shares, at a price per share of $______ per share (the "Purchase Price"), and
each Underwriter hereby agrees, severally and not jointly, to purchase from
Aetna, at the Purchase Price, the number of Firm Shares (subject to such
adjustments to eliminate fractional shares as the Representatives may determine)
set forth opposite the name of such Underwriter in Schedule I.

         On the basis of the representations and warranties contained in this
Agreement, and subject to its terms and conditions, the Company hereby agrees to
issue and sell to the Underwriters, and the Underwriters shall have the right to
purchase, severally and not jointly, from the Company, up to an aggregate of
300,000 Additional Shares at the Purchase Price. Additional Shares may be
purchased solely for the purpose of covering over-allotments made in connection
with the offering of the Firm Shares. The Underwriters may exercise their right
to purchase Additional Shares in whole or in part from time to time by giving
written notice thereof to the Company within 30 days after the date of this
Agreement. The Representatives shall give any such notice on behalf of the
Underwriters and such notice shall specify the aggregate number of Additional
Shares to be purchased pursuant to such exercise and the date for payment and
delivery thereof. The date specified in any such notice shall be



                                       -2-





   3



a business day (i) no earlier than the Closing Date (as hereinafter defined),
(ii) no later than ten business days after such notice has been given and (iii)
no earlier than two business days after such notice has been given. If any
Additional Shares are to be purchased, each Underwriter, severally and not
jointly, agrees to purchase from the Company the number of Additional Shares
(subject to such adjustments to eliminate fractional shares as the
Representatives may determine) that bears the same proportion to the total
number of Additional Shares to be purchased from the Company as the number of
Firm Shares set forth opposite the name of such Underwriter in Schedule I bears
to the total number of Firm Shares purchased by such Underwriter from Aetna.

         Aetna hereby agrees, and the Company shall, concurrently with the
execution of this Agreement, deliver an agreement executed by each of the
directors and executive officers of the Company pursuant to which each such
person agrees, not to directly or indirectly offer, sell, contract to sell,
grant any option to purchase, or otherwise dispose of any capital stock of the
Company or any securities convertible into or exercisable or exchangeable for
such capital stock or in any other manner transfer all or a portion of the
economic consequences associated with the ownership of any such capital stock,
except to the Underwriters pursuant to this Agreement, for a period of 180 days
after the date of the Prospectus, without the prior written consent of the
Representatives (the "Lock-up"), and except any transfers of such capital stock
pursuant to bona fide gifts whereby the transferee agrees in writing to be bound
by the Lock-up.

         3. Terms of Public Offering. The Sellers are advised by you that the
Underwriters propose (i) to make a public offering of their respective portions
of the Shares as soon after the effective date of the Registration Statement as
in your judgment is advisable and (ii) initially to offer the Shares upon the
terms set forth in the Prospectus.

         4. Delivery and Payment. Delivery to the Underwriters of and payment
for the Firm Shares shall be made at 10:00 A.M., New York City time, on the
third or fourth business day, unless otherwise permitted by the Commission
pursuant to Rule 15c6-1 of the Securities Exchange Act of 1934, as amended (the
"Exchange Act") (the "Closing Date") following the date of the public offering,
at the offices of LeBoeuf, Lamb Greene & MacRae, L.L.P., 125 West 55th Street,
New York, New York 10019 against payment therefor by wire transfer or by
certified or official bank check or checks in Federal (same day) funds drawn to
the order of Aetna. The Closing Date and the location of



                                       -3-





   4



delivery of and the form of payment for the Firm Shares may be
varied by agreement between you and the Sellers.

         Delivery to the Underwriters of and payment for any Additional Shares
to be purchased by the Underwriters shall be made at 10:00 A.M., New York City
time, at such place in New York, New York as the Representatives shall designate
on the date specified in the applicable exercise notice given by the
Representatives pursuant to Section 2 (the "Option Closing Date"), against
payment of the purchase price therefor by wire transfer or by certified or
official bank check or checks in Federal (same day) funds drawn to the order of
the Company. Any such Option Closing Date and the location of delivery of and
the form of payment for such Additional Shares may be varied by agreement
between the Representatives and the Company.

         Aetna has prior to the date hereof surrendered its certificates
representing the Firm Shares, along with fully executed stock powers, to the
Company. Certificates for the Shares shall be registered in such names and
issued in such denominations as you shall request in writing not later than two
full business days prior to the Closing Date or the Option Closing Date, as the
case may be. Such certificates shall be made available to you for inspection not
later than 9:30 A.M., New York City time, on the business day next preceding the
Closing Date or the Option Closing Date, as the case may be. Certificates in
definitive form evidencing the Shares shall be delivered to you on the Closing
Date or the Option Closing Date, as the case may be, with any transfer taxes
thereon duly paid by the respective Sellers, for the respective accounts of the
several Underwriters, against payment of the Purchase Price therefor by wire
transfer or certified or official bank checks payable in Federal (same day)
funds to the order of the applicable Sellers.

         5. Agreements of the Company. The Company agrees with you as follows:

         (a) As soon as practicable after the execution and delivery of this
    Agreement, the Company will file (i) if the Registration Statement is not
    yet effective, an amendment to the Registration Statement or (ii) if the
    Registration Statement is already effective, a post-effective amendment to
    the Registration Statement, if necessary, pursuant to Rule 430A under the
    Act. The Company will use its best efforts to cause the Registration
    Statement or such post-effective amendment to become effective at the
    earliest possible time. The Company will comply fully and in a timely manner
    with the applicable provisions of Rules 424 and 430A under the Act.



                                       -4-





   5



         (b) The Company will advise you promptly and, if requested by you, will
    confirm such advice in writing, (i) when the Registration Statement has
    become effective (if such Registration Statement has not become effective
    prior to the execution of this Agreement), if and when any Prospectus is
    filed with the Commission pursuant to Rule 424 under the Act and when any
    post-effective amendment to the Registration Statement becomes effective,
    (ii) of any request by the Commission for amendments to the Registration
    Statement or amendments or supplements to the Prospectus or for additional
    information, (iii) if and when it becomes aware of the issuance by the
    Commission of any stop order suspending the effectiveness of the
    Registration Statement or the issuance by any state securities commission or
    other regulatory authority of any order suspending the qualification or
    exemption from qualification of the Shares for offering or sale in any
    jurisdiction, or the initiation of any proceeding for such purposes, and
    (iv) during the period referred to in paragraph (f) below, if and when it
    becomes aware of any material change in the business, prospects, operations,
    properties, net worth, results of operations or financial condition of the
    Company and its subsidiaries (including, for the purposes of this Agreement,
    any Subsidiary (as hereinafter defined)), taken as a whole, or of the
    happening of any event which makes any statement of a material fact made in
    the Registration Statement or the Prospectus untrue or which requires the
    making of any additions to or changes in the Registration Statement or the
    Prospectus in order to make the statements therein not misleading in any
    material respect. If at any time the Commission shall issue any stop order
    of which the Company becomes aware suspending the effectiveness of the
    Registration Statement or any state securities commission or other
    regulatory authority shall issue an order suspending the qualification or
    exemption from qualification of the Shares, the Company will make every
    reasonable effort to obtain the withdrawal or lifting of such order at the
    earliest possible time.

         (c) The Company will furnish to you, without charge, five signed copies
    of the Registration Statement as first filed with the Commission and of each
    amendment to it, including all exhibits filed therewith or incorporated by
    reference therein, and will furnish to you and each Underwriter designated
    by you such number of conformed copies of the Registration Statement as so
    filed and of each amendment to it, without exhibits, as you may reasonably
    request.



                                       -5-





   6



         (d) The Company will not (i) file any amendment or supplement to the
    Registration Statement, whether before or after the time when the
    Registration Statement becomes effective, or make any amendment or
    supplement to the Prospectus of which you shall not previously have been
    advised or to which you shall reasonably and timely object or (ii) during
    such period as, in the judgment of counsel for the Underwriters, a
    Prospectus is required to be delivered in connection with sales by any
    Underwriter or dealer, file any information, documents or reports pursuant
    to the Securities Exchange Act of 1934, as amended (the "Exchange Act"),
    without delivering a copy of such information, documents or reports to you,
    as the Representatives, prior to, concurrently with or immediately after
    such filing. The Company will prepare and file with the Commission, promptly
    upon your reasonable request, any amendment to the Registration Statement or
    any amendment or supplement to the Prospectus that may be necessary or
    advisable in connection with the distribution of the Shares as determined by
    the Company and the Representatives. The Company will use its best efforts
    to cause any such amendment or supplement to become effective as promptly as
    possible. In the event that the Company and you, as the Representatives,
    agree that the Prospectus should be amended or supplemented, the Company, if
    requested by you, will promptly issue a press release announcing or
    disclosing the matters to be covered by the proposed amendment or
    supplement.

         (e) Prior to the execution and delivery of this Agreement, the Company
    has delivered to you, without charge, in such quantities as you have
    reasonably requested, copies of each form of preliminary prospectus. The
    Company consents to the use, in accordance with the provisions of the Act
    and with the securities, insurance securities or Blue Sky laws of the
    jurisdictions in which the Shares are offered by the several Underwriters
    and by all dealers to whom the Shares may be sold, prior to the date of the
    Prospectus, of each preliminary prospectus.

         (f) Promptly after the Registration Statement becomes effective, and
    from time to time thereafter during such period as in the judgment of
    counsel for the Underwriters a prospectus is required by law to be delivered
    in connection with sales by an Underwriter or a dealer, the Company will
    furnish without charge to each Underwriter and such dealers as you shall
    specify as many copies of the Prospectus (and of each amendment or
    supplement thereto) as such Underwriter or dealer may reasonably request.
    The Company consents to the use of the Prospectus and any amendment or
    supplement



                                       -6-





   7



    thereto by the Underwriters and by all dealers to whom the Shares may be
    sold, both at the time of the offering or sale of the Shares and for such
    period of time thereafter as the Prospectus is required by law to be
    delivered in connection therewith.

         (g) If during the period specified in paragraph (f) any event shall
    occur as a result of which, in the judgment of counsel for the Underwriters,
    it becomes necessary to amend or supplement the Prospectus in order to make
    the statements therein, in the light of the circumstances when the
    Prospectus is delivered to a purchaser, not misleading, or if it is
    necessary to amend or supplement the Prospectus to comply with any law, the
    Company will forthwith prepare and file with the Commission an appropriate
    amendment or supplement to the Prospectus so that the statements in the
    Prospectus, as so amended or supplemented, will not in the light of the
    circumstances when it is so delivered, be misleading, or so that the
    Prospectus will comply with law, and to furnish without charge to each
    Underwriter and to such dealers as you shall specify, such number of copies
    thereof as such Underwriter or dealers may reasonably request.

         (h) Prior to any public offering of the Shares, the Company will
    cooperate with you and with counsel for the Underwriters in connection with
    the registration or qualification of the Shares for offer and sale by the
    several Underwriters and by dealers under the securities, Blue Sky or
    insurance laws governing the offer and sale of securities of such
    jurisdictions as you may request, to continue such qualification in effect
    so long as required for distribution of the Shares and to file such consents
    to service of process or other documents as may be necessary in order to
    effect such registration or qualification.

         (i) The Company will make generally available to its stockholders as
    soon as reasonably practicable, but not later than 60 days after the close
    of the period covered thereby, an earnings statement covering a period of at
    least twelve months beginning not later than the first day of the Company's
    fiscal quarter next following the effective date of the Registration
    Statement which shall satisfy the provisions of Section 11(a) of the Act and
    Rule 158 promulgated thereunder.

         (j) During the period of five years after the date of this Agreement,
    the Company will (i) mail as soon as reasonably practicable after the end of
    each fiscal year to the record holders of the Common Stock a financial
    report of



                                       -7-





   8



    the Company and the Subsidiaries on a consolidated basis, all such financial
    reports to include a consolidated balance sheet, a consolidated statement of
    operations, a consolidated statement of cash flows and a consolidated
    statement of shareholders' equity as of the end of and for such fiscal year,
    together with comparable information as of the end of and for the preceding
    year, certified by independent certified public accountants, and (ii) mail
    and make generally available as soon as practicable after the end of each
    quarterly period (except for the last quarterly period of each fiscal year)
    to such holders, an unaudited consolidated balance sheet, an unaudited
    consolidated statement of operations and an unaudited consolidated statement
    of cash flows as of the end of and for such period, and for the period from
    the beginning of such year to the close of such quarterly period, together
    with comparable information for the corresponding periods of the preceding
    year.

         (k) During the five years after the date of this Agreement, the Company
    will furnish without charge to you, and, upon request, to each of the other
    Underwriters, as soon as available, a copy of each report or other publicly
    available information of the Company mailed to the holders of Common Stock
    or filed with the Commission and such other non-confidential information
    concerning the Company and the Subsidiaries as you may reasonably request.

         (l) Aetna and the Company will pay pro rata, in proportion to the
    number of shares of Common Stock sold by each of them, all costs, expenses,
    fees and taxes incident to (i) the preparation, printing, filing and
    distribution under the Act of the Registration Statement (including
    financial statements and exhibits), each preliminary prospectus and all
    amendments and supplements to any of them, (ii) the preparation, printing,
    filing and delivery of the Prospectus and all amendments or supplements
    thereto, (iii) the printing and delivery of this Agreement, the Preliminary
    and Supplemental Blue Sky Memoranda and all other agreements printed and

    case any reasonable disbursements of counsel for the Underwriters relating
    to such printing and delivery), (iv) the registration with the Commission,
    and the issuance and delivery by the Company, and the delivery by Aetna, of
    the Shares, (v) the registration or qualification of the Shares for offer
    and sale under the securities, Blue Sky or insurance laws governing the
    offer and sale of securities of the several states (including in each case
    the reasonable fees and disbursements of counsel for the Underwriters


                                       -8-





   9



    relating to such registration or qualification and memoranda relating
    thereto), (vi) furnishing such copies of the Registration Statement, the
    Prospectus and any preliminary prospectus, and all amendments and
    supplements thereto, as may be requested for use in connection with the
    offering or sale of the Shares by the several Underwriters or by dealers to
    whom the Shares may be sold, (vii) filings and clearance with the National
    Association of Securities Dealers, Inc. (the "NASD") in connection with the

    the Company's transfer agent and registrar, the cost of its personnel and
    other internal costs, the cost of printing and engraving the certificates
    representing the Shares and all expenses and taxes incident to the sale and
    delivery of the Shares to be sold to the Underwriters other than any
    transfer taxes on resales by the Underwriters); but excluding except as
    expressly provided in clauses (iii) and (v) above, the fees and expenses of
    counsel to the Underwriters.

         (m) From the date hereof and for a period of 180 days after the date of
    the Prospectus, the Company will not directly or indirectly offer, sell,
    contract to sell, grant any option for the sale of, otherwise dispose of,
    file with the Commission a registration statement under the Act to register,
    or announce the sale or offering of, any additional shares of its capital
    stock or any security convertible into or exchangeable or exercisable for
    its capital stock without your prior written consent; provided, however,
    that the foregoing shall not apply to (i) the grant of options to purchase
    shares of Common Stock to employees, officers or directors of the Company
    pursuant to any stock option plan of the Company existing on the date hereof
    (the "Stock Option Plans"), (ii) the issuance of shares of Common Stock

    date of the Registration



                                       -9-





   10



         Statement; provided that any acquisition of an ownership interest in
         the Company resulting in the removal of the Common Stock from the NYSE
         shall not constitute a breach of the agreement contained in this
         Section 5(n).

                  (o) The Company will apply the net proceeds from the sale of
         the Additional Shares in accordance with the description set forth in

                  (p) The Company will use its best efforts to satisfy all
         conditions precedent to the delivery of the Shares.

                  6. Representations and Warranties of the Company. The Company
represents and warrants to each Underwriter that:

                  (a) The Registration Statement has become effective; no stop
         order suspending the effectiveness of the Registration Statement is in
         effect, and no proceedings for such purpose are pending before or
         threatened by the Commission.

                  (b) (i) The Registration Statement, when it became
         effective, did not contain and, as amended or supplemented, if

         necessary to make the statements therein not misleading; (ii) the
         Registration Statement and the Prospectus comply and, as amended or
         supplemented, if applicable, will comply in all material respects with
         the Act; and (iii) the Prospectus does not contain and, as amended or
         supplemented, if applicable, will not contain any untrue statement of a
         material fact or omit to state a material fact necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading, except that the representations and

         or omissions in the Registration Statement or the Prospectus based upon
         information relating to (i) any Underwriter furnished to the Company in
         writing by such Underwriter through you expressly for use therein or
         (ii) Aetna under the caption "Selling Stockholder" furnished to the

         Registration Statement or the Prospectus pursuant to Item 12 of Form
         S-3 under the Act, at the time they were filed or last amended or
         hereafter are filed or amended, as the case may be, with the

         material respects with the requirements of the Exchange Act and, when
         read together and with the other information in the Prospectus, at the
         time the Registration Statement became or becomes effective and at the
         Closing Date and the Option Closing Date, as the case may be, did not
         and will not contain an untrue statement of a material fact or omit to
         state a material fact required to be stated therein or necessary to
         make the statements therein, in the light of the circumstances under
         which they were or are made, not misleading; and any documents deemed
         to be incorporated by reference in the Registration Statement or the
         Prospectus, if and when they were or are filed with the Commission,
         complied with or will comply in all material respects with the
         requirements of the Exchange Act and did not and will not contain an
         untrue statement of a material fact or omit to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading; provided, however, that the representations and
         warranties in this paragraph shall not apply to statements in or
         omissions from the Registration Statement or the Prospectus (or any
         supplement or amendment to them) made based upon and conforming with
         information relating to any Underwriter furnished to the Company in
         writing by or on behalf of any Underwriter through the Representatives
         expressly for use therein.

                  (d) Each preliminary prospectus filed as part of the
         Registration Statement as originally filed or as part of any amendment

         business (the "Insurance Licenses")) which are necessary to own, lease
         and operate its respective properties and to the conduct of its
         businesses as described in the Prospectus, except to the extent the
         failure to hold any such permits or Insurance Licenses (either
         singularly or in the aggregate) would not have a material adverse
         effect on the business, prospects, operations, properties, net worth,

         event that may reasonably be expected to lead to the revocation,
         termination, suspension or any other material impairment of the rights

         Insurance Licenses); and except as disclosed in the Prospectus, the
         Company is not aware of any order or decree of an insurance regulatory

                  (i) The partnership agreement of ERMA has been duly executed
         and delivered by each of the parties thereto and is a valid and binding
         agreement enforceable in accordance with its terms except as (i) rights
         to indemnity and contribution hereunder may be limited by applicable
         law or principles of public policy, (ii) the enforceability thereof may

         injunctive and other forms of equitable relief may be subject to

         (including the Shares to be sold by Aetna) have been duly authorized,
         validly issued, and are fully paid and non-assessable; the Additional
         Shares to be issued and sold by the Company hereunder, if any, have
         been duly authorized and, when issued and delivered to the Underwriters
         against payment therefor as provided by this Agreement, will be validly
         issued, fully paid and non-assessable; no holder of the Shares will be
         subject to personal liability by reason of being such a holder; and
         such Shares are not subject to any preemptive rights.

                  (k) The authorized and outstanding capital stock of the
         Company, including the Common Stock, conforms in all material respects
         to the description thereof incorporated by reference in the Prospectus.

                  (l) Except as described in the Prospectus and except to the

         effect on the business, prospects, operations, properties, net worth,
         results of operations or financial condition of the Company and the
         Subsidiaries, taken as a whole, neither the Company nor any of the
         Subsidiaries is (i) in violation of its respective charter or by-laws,

         decree of any court, governmental agency or body (including, without
         limitation, any insurance regulatory agency or body) or arbitrator
         having jurisdiction over the



                                      -14-

         any of the Subsidiaries is a party or by which it or any of the
         Subsidiaries or their respective property is bound.

                  (m) No consent, approval, waiver, license, authorization,
         order, filing, registration, qualification or other action of or with
         any court, regulatory body, arbitrator, administrative agency or other
         governmental agency or body (including, without limitation, any
         insurance regulatory agency or body) is required for the issuance and
         sale of the Additional Shares, if any, being sold by the Company or the
         execution, delivery and performance of this Agreement, compliance by
         the Company with all the provisions hereof or the consummation of the
         other transactions contemplated hereby or by the Registration Statement

         contained in the Prospectus, except such as have been obtained and made
         under the Act and the Exchange Act, all of which have been or will be
         obtained in accordance with this Agreement and as may be required under
         the insurance securities laws or securities or Blue Sky laws of various
         jurisdictions, and except to the extent that the failure to obtain such

         operations, properties, net worth, results of operations or financial

         of this Agreement, compliance by the Company with all the provisions
         hereof and the consummation of the transactions herein contemplated,
         will not result in the creation or imposition of any lien, charge or
         encumbrance upon any property or assets of the Company or any of the
         Subsidiaries pursuant to the terms of any agreement or instrument to
         which any of them is a party or by which any of them may be bound or to
         which any of the property or assets of any of them is subject, and will
         not conflict with or result in a breach or violation of any of the

         prospects, operations, properties, net worth, results of operations or
         financial condition of the Company and the Subsidiaries, taken as a
         whole.

         Public Utility Holding Company Act of 1935, as amended (the "1935
         Act").

                  (p) There are no contracts, agreements or understandings
         between the Company and any person granting such person the right to
         require the Company to file a registration statement under the Act with

         securities or obligations of the Company convertible into or

         shares, any such convertible or exchangeable securities or obligations,
         or any such warrants, rights or obligations.

                  (t) To the Company's knowledge, neither A.M. Best Company,
         Inc. nor Standard & Poor's Corporation has pending, or has overtly

                  (w) Except as otherwise set forth in the Prospectus (or in the
         documents incorporated therein by reference), there are no material
         pending legal or governmental actions, suits or proceedings to which
         the Company or any of the Subsidiaries is a party or of which any of
         their respective property is the subject, and, to the best of the
         Company's knowledge, no such actions, suits or proceedings are
         threatened or contemplated. No contract or document of a character
         required to be described in the Registration Statement or the
         Prospectus or to be filed as an exhibit to the Registration Statement
         is not so described or filed as required. The descriptions of the terms
         of any such contracts or documents contained in the Registration
         Statement or the Prospectus are correct in all material respects.

                  (x) Neither the Company nor any of the Subsidiaries has

         relating to the protection of human health and safety, the environment

         ("Environmental Laws"), or any federal or state law relating to
         discrimination in the hiring, promotion or pay of employees, or any
         applicable federal or state wages and hours laws, or any provisions of
         the United States Employee Retirement Income Security Act of 1974 and
         the regulations and published interpretations thereunder ("ERISA"),
         which in each case might result in any material adverse change in the
         business, prospects, financial condition or results of operations of
         the Company and the Subsidiaries, taken as a whole.

                  (y) Except as otherwise set forth in the Prospectus (or in
         the documents incorporated therein by reference) or such as are not
         material to the business, prospects, operations, properties, net worth,
         results of operations or financial condition of the Company and the
         Subsidiaries, taken as a whole, the Company and each of the
         Subsidiaries has good and marketable title, free and clear of all
         liens, claims, security interests, encumbrances and restrictions except
         liens for taxes not yet due and payable, to all property and assets
         described in the Registration Statement as being owned by it. All
         material leases to which the Company or any of the Subsidiaries is a
         party are binding on and enforceable against the Company or any such
         Subsidiary, as the case may be, in all material respects and no default
         on the part of the Company or any such Subsidiary, as the case



                                      -18-





   19



         may be, or, to the Company's knowledge, the other party thereto, has
         occurred or is continuing thereunder, which might result in any
         material adverse change in the business, prospects, financial condition
         or results of operations of the Company and the Subsidiaries taken as a
         whole, and the Company and the Subsidiaries enjoy peaceful and
         undisturbed possession under all such leases to which any of them is a
         party as lessee with such exceptions as do not materially interfere
         with the use made by the Company or such Subsidiary.

                  (z) Ernst & Young has informed the Company that they are
         independent public accountants with respect to the Company, as required
         by the Act.

                  (aa) The financial statements, together with related schedules
         and notes, forming part of the Registration Statement and the
         Prospectus (and any amendment or supplement thereto) or incorporated
         therein by reference, present fairly the consolidated financial
         position, results of operations, cash flows and changes in financial
         position of the Company and the Subsidiaries on the basis stated in the
         Registration Statement at the respective dates or for the respective
         periods to which they apply; such statements and related schedules and
         notes have been prepared in accordance with generally accepted
         accounting principles consistently applied throughout the periods
         involved, except as disclosed therein and except that quarterly
         financial statements contained in the Registration Statement are
         subject to year-end adjustments; and the other financial and
         statistical information and data set forth in the Registration
         Statement and the Prospectus (and any amendment or supplement thereto)
         is, in all material respects, accurately presented and prepared on a
         basis consistent with such financial statements and the books and
         records of the Company. The pro forma financial statements of the

         on the date hereof, except to the extent any such representation or

         the ability of Aetna to perform its obligations under this Agreement,
         or that are not otherwise material in the context of the sale of the
         Firm Shares,

                                      -25-





   26



                  (e) Aetna is not (a) an "investment company" or a company
         "controlled" by an "investment company" within the meaning of the

         Aetna's knowledge, no such actions, suits or proceedings are threatened
         or contemplated. No contract or document pertaining to Aetna of a

         corporate power and authority to enter into this Agreement and to sell,
         assign, transfer and deliver such Firm Shares to you hereunder, and the
         execution and delivery of this Agreement, and the performance by it of
         its obligations hereunder (including without limitation the sale of the
         Firm Shares to be sold thereby), have been duly authorized by all
         necessary corporate action on the part of Aetna; and upon the delivery
         of and payment for the Firm Shares hereunder, the several Underwriters
         will acquire valid and unencumbered title to the Firm Shares purchased
         by them from Aetna, free and clear of any and all restrictions on
         transfer, liens, charges, encumbrances, security interests and claims
         whatsoever, assuming such Underwriters acquire such shares without
         notice of any adverse claims; and Aetna has not entered into any
         agreement with any third party or taken any other action the effect of
         which would be to subject the Firm Shares to any restrictions on
         transfer, lien, charge, encumbrance, security interest or any other
         claim whatsoever which has not been legally and validly waived.

         hereto, does not, and will not on the Closing Date, contain
         any untrue statement of material fact or omit to state any material
         fact required to be stated therein or necessary to make the statements
         therein, in light of the circumstances under which they were made, not
         misleading.

                  (i) Aetna has not taken and will not take, directly or
         indirectly, any action designed to, or which might reasonably be
         expected to, cause or result in the stabilization or manipulation of
         the price of any security of the Company to facilitate the sale or
         resale of the Shares pursuant to the distribution contemplated by this
         Agreement, and other than as permitted by the Act, Aetna has not
         distributed and will not distribute, prior to the later to occur of (i)
         the Closing Date or the Option Closing Date and (ii) completion of the
         distribution of the Shares, any prospectus or other offering material
         in connection with the offering and sale of the Shares.

                  (j) At any time during the period described in paragraph 5(f)
         hereof, if there is any change in the information referred to in
         paragraph 7(h) above, Aetna shall immediately notify you of such
         change.

                  8. Indemnification and Contribution. (a) The Company will
indemnify and hold harmless each Underwriter and each person, if any, who
controls any Underwriter within the meaning of Section 15 of the Act or Section
20 of the Exchange Act, from and against any and all losses, claims, damages,
judgments, or liabilities, joint or several, to which such Underwriter may
become subject, under the Act or otherwise, only insofar as such losses, claims,
damages, judgments or liabilities (or actions in respect thereof) arise out of
or are based upon any untrue statement or alleged untrue statement of any
material fact contained in the Registration Statement, the Prospectus or any
amendment or supplement thereto, or any preliminary prospectus, or arise out of
or are based upon any omission or alleged omission to state therein a material
fact required to be stated therein or necessary to make the statements therein
not misleading, and will reimburse each Underwriter for any legal or other
expenses reasonably incurred by such Underwriter in connection with
investigating or defending any such loss, claim, damage, judgment, liability or
action as such expenses are incurred; provided, however, that the Company will
not be liable in any such case to the extent that any such loss, claim, damage,
judgment or liability arises out of or is based upon an untrue statement or
alleged untrue statement in or omission or alleged omission from any of such
documents in reliance upon and in


                                      -27-

conformity with written information furnished to the Company by any Underwriter
relating to the Underwriter through you, or by Aetna under the caption "Selling
Stockholder," in either case expressly for use therein; provided, however, that
the foregoing indemnity with respect to any preliminary prospectus shall not
inure to the benefit of any Underwriter from whom the person asserting any such
losses, claims, damages or liabilities purchased Shares, or any person
controlling such Underwriter, if a copy of the Prospectus (as then amended or
supplemented if the Company shall have furnished any amendments or supplements
thereto), other than the documents incorporated by reference therein, was timely
made available by the Company to such Underwriter and was not delivered by or on
behalf of such Underwriter to such person, if required by the Act so to have
been delivered, at or prior to the written confirmation of the sale of the
Shares to such person, and if the Prospectus (as so amended or supplemented)
would have cured the defect contained in such preliminary prospectus giving rise
to such losses, claims, damages or liabilities.

                  (b) Aetna will indemnify and hold harmless each Underwriter
and each person, if any, who controls any Underwriter within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act from and against any and
all losses, claims, damages, judgments or liabilities, joint or several, to
which such Underwriter may become subject, under the Act or otherwise, only
insofar as such losses, claims, damages, judgments or liabilities (or actions in
respect thereof) arise out of or are based upon any untrue statement or alleged
untrue statement of any material fact contained in the Registration Statement,
the Prospectus or any amendment or supplement thereto, or any preliminary
prospectus, or arise out of or are based upon any omission or alleged omission
to state therein a material fact required to be stated therein or necessary to
make the statements therein not misleading, in each case to the extent, but only
to the extent that such untrue statement or alleged untrue statement or omission
or alleged omission was contained in those specific sections of the prospectus
describing Aetna and/or AC&S and/or the business relationships of Aetna and/or
AC&S with the Company and its Subsidiaries as identified in Exhibit A hereto,
and will reimburse each Underwriter for any legal or other expenses reasonably
incurred by such Underwriter in connection with investigating or defending any
such loss, claim, damage, judgment, liability or action as such expenses are
incurred; provided, however, that the foregoing indemnity with respect to any
preliminary prospectus shall not inure to the benefit of any Underwriter from
whom the person asserting any such losses, claims, damages or liabilities
purchased Shares, or any person controlling such Underwriter, if a copy of the
Prospectus (as then amended or supplemented if Aetna shall have furnished any



                                      -28-





   29



amendments or supplements thereto), other than the documents incorporated by
reference therein, was timely made available by Aetna to such Underwriter and
was not delivered by or on behalf of such Underwriter to such person, if
required by the Act so to have been delivered, at or prior to the written
confirmation of the sale of the Shares to such person, and if the Prospectus (as
so amended or supplemented) would have cured the defect contained in such
preliminary prospectus giving rise to such losses, claims, damages or
liabilities. Notwithstanding any other provision of this Agreement, the
aggregate liability of Aetna for indemnification or contribution under this
Agreement shall not exceed an amount equal to the proceeds of the sale of the
Shares being sold by Aetna after deduction of underwriting discounts and
commissions and all costs and expenses required to be paid by it under this
Agreement.

                  (c) Each Underwriter, severally and not jointly, will
indemnify and hold harmless the Company, each officer of the Company who signs
the Registration Statement, each director of the Company, Aetna and each person,
if any, who controls the Company or Aetna within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act from and against any and all losses,
claims, damages, judgments or liabilities to which the Company, such officers
and directors or Aetna may become subject, under the Act or otherwise, insofar
as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon any untrue statement or alleged untrue statement
of any material fact contained or incorporated by reference in the Registration
Statement, the Prospectus or any amendment or supplement thereto, or any
preliminary prospectus, or arise out of or are based upon any omission or
alleged omission to state therein a material fact required to be stated therein
or incorporated by reference therein or necessary to make the statements 
therein or incorporated by reference therein not misleading, in each case to 
the extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in reliance upon and in
conformity with written information furnished to the Company by such
Underwriter, or by such Underwriter through you, expressly for use in the
preparation thereof, and will reimburse the Company, such officers and
directors, Aetna or any such control person for any legal or other expenses
reasonably incurred by the Company, such officers and directors, Aetna or any
such control person in connection with investigating or defending any such loss,
claim, damage, judgment, liability or action as such expenses are incurred.

                  (d) Promptly after receipt by an indemnified party under this
Section of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to



                                      -29-





   30



be made against an indemnifying party under subsection (a), (b) or (c) above,
notify the indemnifying party of the commencement thereof and the indemnifying
party shall assume the defense thereof, including the employment of counsel
reasonably satisfactory to such indemnified party and payment of all fees and
expenses; but the omission so to notify the indemnifying party will not relieve
it from any liability which it may have to any indemnified party otherwise than
under subsection (a), (b) or (c) above. An indemnified party shall have the
right to employ separate counsel in any such action or proceeding and to
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of such indemnified party unless (i) the employment of
such counsel has been specifically authorized in writing by the indemnifying
parties, (ii) the indemnifying parties have failed promptly to assume the
defense and employ counsel reasonably satisfactory to the indemnified party
(which payment of fees and expenses of separate counsel by the indemnifying
parties shall cease upon such assumption of defense by the indemnifying parties)
or (iii) the named parties to any such action or proceeding (including any
impleaded parties) include both the indemnified party and the indemnifying
parties and representation of both parties by the same counsel would be
inappropriate due to actual or potential differences between them (in which case
the indemnifying parties shall not have the right to assume the defense of such
action on behalf of such indemnified party), it being understood, however, that
the Company and Aetna shall not, in connection with any one such action or
separate but substantially similar or related actions in the same jurisdiction
arising out of the same general allegations or circumstances, be liable for the
fees and expenses of more than one separate firm of attorneys (in addition to
any local counsel) for all such Underwriters and controlling persons, which firm
shall be designated in writing by Donaldson, Lufkin & Jenrette Securities
Corporation and that all such fees and expenses shall be reimbursed as they are
incurred). The indemnifying party shall not be liable for any settlement of any
such action affected without the written consent of the indemnifying parties,
but if settled with a written consent of the indemnifying parties, or if there
is a final judgment with respect thereto or with respect to the indemnifying
parties' liability therefore, the indemnifying parties agree to indemnify and
hold harmless each indemnified party from and against any loss or liability by
reason of such settlement or judgment (if and to the extent required hereby).
The indemnifying party shall not, without the prior written consent of each
indemnified party affected thereby, effect any settlement of any pending or
threatened proceeding in which such indemnified party could have sought
indemnity hereunder, unless such settlement includes an unconditional release of
such indemnified party from all liability for which there is an indemnification
obligation hereunder.

   31




                  (e) If the indemnification provided for in this Section 8 is
unavailable or insufficient to hold harmless an indemnified party, then each
indemnifying party shall contribute to the amount paid or payable by such
indemnified party as a result of the losses, claims, damages, judgments or
liabilities referred to in subsection (a), (b), (c) or (d) above (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Sellers on the one hand and the Underwriters on the other hand from the offering
of the Shares or (ii) if the allocation provided by clause (i) above is not
permitted by applicable law, in such proportion as is appropriate to reflect not
only the relative benefits referred to in clause (i) above but also the relative
fault of the Sellers on the one hand and the Underwriters on the other hand in
connection with the statements or omissions which resulted in such losses,
claims, damages, judgments or liabilities as well as any other relevant
equitable considerations. The relative benefits received by the Sellers on the
one hand and the Underwriters on the other hand shall be deemed to be in the
same proportion as the total net proceeds from the offering (before deducting
expenses) received by the Sellers and the total underwriting discounts and
commissions received by the Underwriters, bear to the total price to the public
of the Shares, in each case as set forth in the table on the cover page of the
Prospectus. The relative fault of the Sellers on the one hand and the
Underwriters on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company, Aetna or the Underwriters and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such untrue statement or omission. The Sellers and the Underwriters agree that
it would not be just and equitable if contribution pursuant to this Section 8(e)
were determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation which does not
take account of the equitable considerations referred to in the immediately
preceding paragraph. The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, judgments or liabilities referred to in
the first sentence of this subsection (e) shall be deemed to include, subject to
the limitations set forth above, any legal or other expenses reasonably incurred
by such indemnified party in connection with investigating or defending any
action or claim which is the subject of this subsection (e). Notwithstanding the
provisions of this subsection (e), no Underwriter shall be required to
contribute any amount in excess of the amount by which the total price at which
the Shares underwritten by it and distributed to the public were offered to the
public exceeds the amount of any damages which such Underwriter has otherwise
been required to pay


                                      -31-





   32



by reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(e) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation. The Underwriters'
obligations in this subsection (e) to contribute are several in proportion to
the respective number of shares purchased by each of the Underwriters hereunder
and not joint.

                  (f) The obligations of the Company and Aetna under this
Section shall be in addition to any liability which the Company and Aetna
otherwise may have and shall extend, upon the same terms and conditions, to each
person, if any, who controls any Underwriter within the meaning of the Act; and
the obligations of the Underwriters under this Section shall be in addition to
any liability which the respective Underwriters may otherwise have and shall
extend, upon the same terms and conditions, to each director of the Company, to
each person who has consented to become a director of the Company, to each
officer of the Company who has signed the Registration Statement and to each
person, if any, who controls the Company or Aetna within the meaning of the Act.

                  9. Conditions of Underwriters' Obligations. The several
obligations of (i) the Underwriters to purchase the Firm Shares and (ii) the
Underwriters pursuant to their option to purchase the Additional Shares under
this Agreement are subject to the satisfaction of each of the following
conditions:

                  (a) All the representations and warranties of the Company
         contained in this Agreement shall be true and correct on the Closing
         Date (with respect to the Firm Shares) and the Option Closing Date
         (with respect to the Additional Shares) with the same force and effect
         as if made on and as of the Closing Date or Option Closing Date, as the
         case may be. The Company shall have performed or complied with all
         agreements and satisfied all conditions on its part to be performed or
         complied with by the Company at or prior to the Closing Date or the
         Option Closing Date, as the case may be.

                  (b) (i) The Registration Statement shall have become effective
         not later than 5:00 P.M. (and in the case of a Registration Statement
         filed under Rule 462(b) of the Act, not later than 10:00 P.M.), New
         York City time, on the date of this Agreement or at such later date and
         time as you may approve in writing, (ii) all filings, if any, required
         by Rules 424 and 430A under the Act shall have been timely made, (iii)
         at the Closing Date and the Option Closing Date no stop order
         suspending the effectiveness of the



                                      -32-





   33



         Registration Statement or any post-effective amendment to the
         Registration Statement shall have been issued and no proceedings for
         that purpose shall have been commenced or shall be pending before or
         contemplated by the Commission and (iv) any request of the Commission
         for additional information (to be included in the Registration
         Statement or the Prospectus or otherwise) shall have been complied with
         to your reasonable satisfaction. No stop order suspending the sale of
         the Shares in any jurisdiction shall have been issued and no
         proceedings for that purpose shall have been commenced or shall be
         pending or contemplated.

                  (c) (i) Since the date of the latest balance sheet included in
         the Registration Statement and the Prospectus, there shall not have
         been any material adverse change in, or affecting the affairs,
         business, prospects, operations, properties, net worth, results of
         operations or financial condition, whether or not arising in the
         ordinary course of business, of the Company or any of the Subsidiaries,
         (ii) since the date of the latest balance sheet included in the
         Registration Statement and the Prospectus, (iii) since the date of the
         latest balance sheet included in the Registration Statement and
         Prospectus, and except as disclosed therein, none of the Company or any
         of the Subsidiaries shall have incurred any liabilities or obligations,
         direct or contingent (whether or not in the ordinary course of
         business), or entered into any transactions, not in the ordinary course
         of business, that are material, individually or in the aggregate, to
         the business of the Company and the Subsidiaries taken as a whole and
         (iv) on the Closing Date and the Option Closing Date, you shall have
         received a certificate dated the Closing Date or the Option Closing
         Date, as the case may be, signed by two of: LeRoy A. Vander Putten,
         Robert H. Kullas and Robert V. Deutsch, solely in their respective
         capacities as the Chairman and Chief Executive Officer, Vice Chairman
         and Chief Operating Officer and Executive Vice President and Chief
         Financial Officer of the Company, confirming the matters set forth in
         paragraphs (a), (b), and (c) of this Section 9.

                  (d) All the representations and warranties of Aetna contained
         in this Agreement shall be true and correct on the Closing Date with
         the same force and effect as if made on and as of the Closing Date.
         Aetna shall have performed or complied with all agreements and
         satisfied all conditions on its part to be performed or complied with
         by it at or prior to the Closing Date and you shall have received a
         certificate to such effect, dated the Closing Date, from


                                      -33-





   34



         Aetna with respect to the matters set forth in this paragraph.

                  (e) You shall have received an opinion (reasonably
         satisfactory to you and counsel for the Underwriters), dated the
         Closing Date or the Option Closing Date, as the case may be, of Dewey
         Ballantine, counsel for the Company, to the effect that:

                           (i) The Company and each of ERI, ERII and Talcott
                  (collectively, the "Delaware Subsidiaries") is a corporation
                  duly organized, validly existing and in good standing under
                  the laws of the jurisdiction in which it was organized and has
                  all requisite power and authority to conduct its business as
                  it is currently being conducted and to own, lease and operate
                  its properties. The Company and each of the Delaware
                  Subsidiaries (other than ERMA) is duly qualified as a foreign
                  corporation authorized to transact business in and is in good
                  standing in each jurisdiction in which the nature of its
                  business or its ownership or leasing of property requires such
                  qualification, except where the failure to be so qualified
                  would not have a material adverse effect on the business,
                  prospects, operations, properties, net worth, results of
                  operations or financial condition of the Company and the
                  Subsidiaries considered as a whole. The partnership agreement
                  of ERMA has been duly executed and delivered by the Company
                  and ERI. To the best of such counsel's knowledge, the only
                  partners of ERMA are the Company and ERI.

                           (ii) All of the outstanding shares of capital stock
                  of, or other ownership interests in, each Delaware Subsidiary
                  of the Company have been, as applicable, duly authorized and
                  validly issued and, in the case of shares of capital stock,
                  are fully paid and non-assessable, and all such shares and
                  other ownership interests owned of record by the Company or by
                  a Delaware Subsidiary are owned free and clear of any
                  perfected security interest and, to the best of such counsel's
                  knowledge, any lien, claim, encumbrance or adverse interest of
                  any nature, except (A) with respect to the stock of ERI, for
                  the lien of The Chase Manhattan Bank (National Association),
                  as Agent (the "Agent"), pursuant to the Stock Pledge Agreement
                  dated as of March 26, 1996 between the Company and the Agent
                  entered into in connection with that certain Term Loan
                  Agreement dated as of March 26, 1996 among the Company, the
                  Banks signatory thereto and the Agent, and (B) with



                                      -34-





   35



                  respect to the stock of ERII, for the lien of The Chase
                  Manhattan Bank (National Association), as Agent (the "Agent"),
                  pursuant to the Stock Pledge Agreement dated as of March 26,
                  1996 between ERI and the Agent entered into in connection with
                  that certain Term Loan Agreement dated as of March 26, 1996
                  among the Company, the Banks signatory thereto and the Agent.

                           (iii) Other than as described in the Prospectus, to
                  the best of such counsel's knowledge, there are no outstanding
                  warrants, rights or options to acquire, or instruments
                  convertible into or exchangeable for, or any obligation of the
                  Company to issue any shares of capital stock or other equity
                  interests in the Company or any of the Subsidiaries.

                           (iv) All the outstanding shares of capital stock of
                  the Company (including the Shares to be sold by Aetna) have
                  been duly authorized, validly issued, and are fully paid and
                  non-assessable; and the Additional Shares to be issued and
                  sold by the Company hereunder have been duly authorized and,
                  when issued and delivered to the Underwriters against payment
                  therefor as provided by this Agreement, will be validly
                  issued, fully paid and non-assessable; no holder of the Shares
                  will be subject to personal liability by reason of being such
                  a holder; and such Shares are not subject to any preemptive
                  rights of any stockholder of the Company under Delaware
                  General Corporation Law except as described in the Prospectus.

                           (v) To the best of such counsel's knowledge, there
                  are no contracts or agreements between the Company and any
                  person granting such person the right to require the Company
                  to file a registration statement under the Act with respect to
                  any securities of the Company owned or to be owned by such
                  person or to require the Company to include such securities in
                  the securities registered pursuant to the Registration
                  Statement or in any securities being registered pursuant to
                  any other registration statement filed by the Company under
                  the Act, except as provided in the Securityholders Agreement.

                           (vi) No consent, approval, waiver, license,
                  authorization, order, filing, registration, qualification or
                  other action of or with any court, regulatory body,
                  arbitrator, administrative agency or other governmental agency
                  or body (including, without limitation, any insurance
                  regulatory agency or body) is



                                      -35-





   36



                  required for the issuance and sale of the Additional Shares or
                  the execution, delivery and performance of this Agreement by
                  the Company, compliance by the Company with all the provisions
                  hereof or the consummation of the other transactions
                  contemplated hereby or by the Registration Statement, except
                  such as have been obtained and made under the Act and the
                  Exchange Act, all of which have been or will be obtained in
                  accordance with this Agreement, and as may be required under
                  the insurance securities laws or securities or Blue Sky laws
                  of various jurisdictions.

                           (vii) To the best of such counsel's knowledge, the
                  issuance and sale of the Shares to be sold by the Company
                  under this Agreement and the execution, delivery and
                  performance of this Agreement by the Company, compliance by
                  the Company with all the provisions hereof and the
                  consummation by the Company of the transactions herein
                  contemplated, will not result in the creation or imposition of
                  any lien, charge or encumbrance upon any property or assets of
                  the Company or any of the Subsidiaries pursuant to the terms
                  of any agreement or instrument to which any of the Company and
                  its Subsidiaries is a party or by which any of them may be
                  bound or to which any of the property or assets of any of them
                  is subject except, in all instances to the extent that any
                  such creation or imposition would not have a material adverse
                  effect on the business, prospects, operations, properties, net
                  worth, results of operations or financial condition of the
                  Company and its Subsidiaries, taken as a whole, and will not
                  conflict with or result in a breach or violation of any of the
                  terms and provisions of, or constitute a default (with notice
                  or the passage of time) under, (i) any statute, rule,
                  regulation or order, of any governmental agency or body
                  (including, without limitation, any insurance regulatory
                  agency or body) or any court or arbitrator, which is
                  applicable to the Company or any Subsidiary or any of their

                  or any such Subsidiary except, in the case of clauses (i) and

                  worth, results of operations or financial condition of
                  the Company and the Subsidiaries, taken as a whole.

                           (viii) Such counsel has been informed by the staff of
                  the Commission that the Registration Statement and all
                  post-effective amendments, if any, have become effective under
                  the Act, the Prospectus either was filed with the Commission
                  pursuant to the subparagraph of Rule 424(b) specified in such
                  opinion on the date specified therein or was included in the
                  Registration Statement (as the case may be), and to such
                  counsel's knowledge no stop order suspending the effectiveness
                  of the Registration Statement or any part thereof has been
                  issued and to such counsel's knowledge no proceedings for that
                  purpose have been instituted or are pending or are
                  contemplated under the Act.

                           (ix) Each document filed pursuant to the 1934 Act and
                  incorporated by reference in the Prospectus, at the time it
                  was filed or last amended (other than financial statements or
                  other financial information or statistical data included
                  therein, as to which no opinion need be rendered), complied as
                  to form in all material respects to the requirements of the
                  Exchange Act and the regulations adopted in connection
                  therewith.

                           (x) To the best of such counsel's knowledge, except
                  as otherwise set forth in the Prospectus, there are no pending
                  legal or governmental actions, suits or proceedings to which
                  the Company or any of the Subsidiaries is a party or of which
                  any of their respective property is the subject and which are
                  required to be described or incorporated by reference in the
                  Registration Statement or the Prospectus, and, to the best of
                  such counsel's knowledge, no such actions, suits or
                  proceedings are threatened or contemplated, and no contract or
                  document of a character required to be described or
                  incorporated by reference in the Registration Statement or the

                  Statement is not so described or filed or incorporated by
                  reference as required, and the descriptions of the terms of
                  any such contracts or documents contained or incorporated by
                  reference in the Registration Statement or the Prospectus are
                  correct in all material respects.

                           (xi) This Agreement has been duly authorized,
                  executed and delivered by the Company and is a valid

                  of specific performance and injunctive and other forms of
                  equitable relief may be subject to equitable defenses and to
                  the discretion of the court before which any proceeding
                  therefor may be brought.

                           (xii) The authorized capital stock of the Company,
                  including the Common Stock, conforms in all material respects
                  to the description thereof contained or incorporated by

                           (xiii) The statements under the captions "Risk

                  proceedings or refer to statements of regulation, law or legal
                  conclusions, are accurate in all material respects.

                           (xiv) Neither the Company nor any of the Subsidiaries
                  is (A) in violation of its respective charter or by-laws, or
                  other organizational documents, or, to the best of such
                  counsel's knowledge, except as described in the Prospectus and
                  except to the extent that any of the following would not have
                  a material adverse effect on the business, prospects,
                  operations, properties, net worth, results of operations or

                  Company or any of the Subsidiaries, or (C) in default in the

                  of indebtedness or in any other agreement,

                  indenture, lease or instrument that is an exhibit to
                  the Registration Statement.

                           (xv) To the best of such counsel's knowledge after
                  due inquiry, all material leases to which the Company or any
                  of the Subsidiaries is a party are valid and binding on the
                  Company or such Subsidiary, as the case may be, and no default
                  has occurred or is continuing thereunder, which might result
                  in any material adverse change in the business, prospects,
                  financial condition or results of operation of the Company and
                  the Subsidiaries taken as a whole.

                           (xvi) To such counsel's knowledge, each of the
                  Company and its Subsidiaries holds such licenses,
                  certificates, permits, franchises and authorizations from
                  insurance departments and other governmental or regulatory
                  authorities ("permits") (including, without limitation,
                  Insurance Licenses) which are necessary to own, lease and
                  operate its properties and to conduct its business as
                  described in the Prospectus, except to the extent the failure
                  to hold any such permits or Insurance Licenses (either
                  singularly or in the aggregate) would not have a material
                  adverse effect on the business, prospects, operations,
                  properties, net worth, results of operations or financial
                  condition of the Company and the Subsidiaries taken as a
                  whole; to the best of such counsel's knowledge, all such
                  permits and the Insurance Licenses are in full force and
                  effect. Except as disclosed in the Prospectus, to the best of
                  such counsel's knowledge, there has been, and there is no,
                  pending or threatened action, suit, proceeding, investigation
                  or event that may reasonably be expected to lead to the
                  revocation, termination, suspension or any other material
                  impairment of the rights of the holder of any such permit
                  (including, without limitation, the Insurance Licenses); to
                  the best of such counsel's knowledge, such permits and
                  Insurance Licenses do not materially restrict the conduct of
                  business of the Company or any of the Subsidiaries except as
                  described in the Prospectus and except for any restrictions
                  customarily found in insurance licenses generally; and except
                  as disclosed or incorporated by reference in the Prospectus,
                  to the best of such counsel's knowledge, no insurance
                  regulatory agency or body has issued any order or decree
                  impairing, restricting or prohibiting the payment of dividends
                  by any of the Subsidiaries of the Company to its parent.

                           (xvii) The Company is not (a) an "investment company"
                  or a company "controlled" by an "investment company" within
                  the meaning of the Investment Company Act or (b) a "holding
                  company" or a "subsidiary company" of a "holding company" or
                  an "affiliate" of a "holding company" or of a "subsidiary
                  company" of a "holding company" within the meaning of the 1935
                  Act.

                           (xviii) (i) The Registration Statement and any
                  post-effective amendment thereto, at the time such
                  Registration Statement or such post-effective amendment became
                  or becomes effective, complies or will comply in all material
                  respects with the provisions of the Act; and (ii) the
                  Prospectus, and any supplement or amendment thereto, on the
                  date of filing thereof with the Commission and on the Closing
                  Date and the Option Closing Date, complies and will comply in
                  all material respects with the provisions of the Act; provided
                  that such counsel need express no view on the financial
                  statements and the notes thereto and the schedules and other
                  financial, statistical and accounting data included therein.

                           (xix) The Company has corporate power and authority
                  to enter into this Agreement and to issue, sell and deliver
                  the Additional Shares to be sold by it to the Underwriters as
                  provided herein. The performance by the Company of its
                  obligations hereunder (including without limitation the
                  issuance and sale of the Additional Shares), has been duly
                  authorized by all necessary corporate action on the part of
                  the Company.

                           (xx) The form of certificate for the Shares conforms
                  in all material respects to the requirements of the Delaware
                  General Corporation Law and the NYSE.

                           (xxi) To the best of such counsel's knowledge, after
                  due inquiry, no relationship, direct or indirect, or
                  agreement, (including, without limitation, any voting
                  agreement), exists between or among the Company or any of the
                  Subsidiaries and any other party or any of their respective
                  affiliates, which is required by the Act to be described or
                  incorporated by reference in the Registration Statement or the
                  Prospectus or to be filed as an exhibit to the Registration
                  Statement which is not described or incorporated by reference
                  or filed as required.

                           (xxii) The Stock Purchase Agreement has been duly
                  executed and delivered by the Company. The Stock



                                      -40-





   41



                  Repurchase and all other transactions contemplated by the
                  Stock Purchase Agreement that are required to have been
                  consummated prior to the date hereof have been duly
                  consummated as described in the Prospectus in compliance in
                  all material respects with applicable law, including without
                  limitation applicable federal and state securities laws,
                  except to the extent that the failure to comply would not have
                  a material adverse effect on the business, prospects,
                  operations, properties, net worth, results of operations or
                  financial condition of the Company and the Subsidiaries, taken
                  as a whole.

                           (xxiii) To the best of such counsel's knowledge,
                  after due inquiry, there are no pending or threatened claims,
                  actions, suits or proceedings arising out of or in connection
                  with the consummation of the transactions contemplated by the
                  Stock Purchase Agreement.

                  Such counsel shall also state that although such counsel has
not undertaken to determine independently, and therefore does not assume any
responsibility explicitly or implicitly for, the accuracy, completeness or
fairness of the statements contained in the Registration Statement and in the
Prospectus, such counsel has participated in the preparation of the Registration
Statement and the Prospectus, including review and discussion of the contents
thereof, and that based upon and subject to the foregoing, nothing came to such
counsel's attention that caused them to believe that the Registration Statement,
at the time it became effective, contained an untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, or that the Prospectus,
as of its date and as of the date of such opinion, contained or contains an
untrue statement of a material fact or omitted or omits to state a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading (except in
each case as to the financial statements and the notes thereto and the schedules
and other financial and statistical data included therein, as to which such
counsel need express no belief).

                  As to factual matters, such counsel may rely on certificates
obtained from officers of the Company and the Subsidiaries and from public
officials and on such other authority as such counsel deems reasonable. In
rendering such opinion counsel may rely upon an opinion or opinions, each dated
the Closing Date, of other counsel retained by them or the Company as to laws of
any jurisdiction other than the United States or the States of New York and
Delaware, provided that



                                      -41-

(1) each such local counsel is reasonably acceptable to the Representatives and
their counsel, (2) such reliance is expressly authorized by each opinion so
relied upon and a copy of each such opinion is delivered to the Representatives
and is in form and substance reasonably satisfactory to the Representatives and
their counsel.

                  (f) You shall have received opinions (reasonably satisfactory
         to you and to counsel for the Underwriters), dated the Closing Date, of
         counsel to Aetna, which counsel are reasonably satisfactory to you and
         to counsel for the Underwriters, to the effect that:

                  approval required by law (other than any approval imposed by
                  the applicable state securities and Blue Sky laws) to enter
                  into this Agreement and to sell, assign, transfer and deliver
                  the Shares to be sold by Aetna in the manner provided herein
                  and therein, and this Agreement has been duly authorized,
                  executed and delivered by Aetna and is a valid and binding
                  agreement of Aetna enforceable in accordance with its terms
                  except as (i) rights to indemnity and contribution hereunder
                  may be limited by applicable law or principles of public
                  policy, (ii) the enforceability hereof may be limited by
                  bankruptcy, insolvency, reorganization, moratorium or other
                  similar laws now or hereafter in effect relating to creditors'
                  rights generally and (iii) the remedy of specific performance
                  and injunctive and other forms of equitable relief may be
                  subject to equitable defenses and to the discretion of the
                  court before which any proceeding therefor may be brought.

                           (ii) To such counsel's knowledge, no consent,
                  approval, waiver, license, authorization, order, filing,
                  registration, qualification or other action of or with any
                  court, regulatory body, administrative agency or other

                  consummation by Aetna of the other transactions contemplated
                  hereby or by the Registration Statement, except such as have
                  been obtained and made under the Act and the Exchange Act, all
                  of which have been or


                                      -42-

                  will be obtained in accordance with this Agreement, and as may
                  be required under the insurance securities laws or securities
                  or Blue Sky laws of various jurisdictions.

                           (iii) The execution, delivery and performance by
                  Aetna of this Agreement, compliance by Aetna with all the
                  provisions hereof and the consummation of the transactions
                  herein contemplated will not conflict with or result in a
                  breach or violation of any of the terms and provisions of (A)
                  the organizational documents of Aetna, or, to such counsel's
                  knowledge, (B) any obligation, agreement or condition
                  contained in any bond, debenture, note or any other evidence
                  of indebtedness or in any other agreement, indenture, lease or
                  instrument or (C) any law, regulation or rule or any judgment,
                  injunction, order or decree of any court, governmental agency
                  or body (including, without limitation, any insurance
                  regulatory agency or body) or arbitrator having jurisdiction
                  over Aetna that, in the case of either (B) or (C), is material
                  to the business of Aetna.

                           (iv) The Amended and Restated Stock Purchase
                  Agreement has been duly authorized, executed and delivered by
                  Aetna and is a valid and binding agreement of Aetna
                  enforceable in accordance with its terms except as (i) rights
                  to indemnity and contribution hereunder may be limited by
                  applicable law or principles of public policy, (ii) the
                  enforceability hereof may be limited by bankruptcy,
                  insolvency, reorganization, moratorium or other similar laws
                  now or hereafter in effect relating to creditors' rights
                  generally and (iii) the remedy of specific performance and
                  injunctive and other forms of equitable relief may be subject
                  to equitable defenses and to the discretion of the court
                  before which any proceeding therefor may be brought.

                           (v) Upon due delivery and payment for the Shares to
                  be sold by the Selling Stockholder as provided for in this
                  Underwriting Agreement, the Underwriters will have good and
                  valid title to the Shares so transferred, free and clear of
                  any liens, encumbrances, equities or claims (assuming that the
                  Underwriters are without notice of any adverse claim, as
                  defined in the Uniform Commercial Code as adopted in the State
                  of New York). Aetna has good and clear title to the
                  certificates for the Firm Shares to be sold by it and upon
                  delivery thereof, pursuant hereto and



                                      -43-





   44



                  payment therefor, good and clear title will pass to the
                  Underwriters, severally, free of all restrictions on transfer,
                  liens, encumbrances, security interests and claims whatsoever.

                           (vi) Aetna is not (a) an "investment company" or a
                  company "controlled" by an "investment company" within the
                  meaning of the Investment Company Act or (b) a "holding
                  company" or a "subsidiary company" of a "holding company" or
                  an "affiliate" of a "holding company" or of a "subsidiary
                  company" of a "holding company" within the meaning of the 1935
                  Act.

                  As to factual matters, such counsel may rely on certificates
obtained from officers of the Company or Aetna and from public officials and
such other authority as such counsel deems reasonable.

                  (g) You shall have received an opinion (reasonably
         satisfactory to you and counsel for the Underwriters), dated the
         Closing Date or the Option Closing Date, as the case may be, of
         Timothy Curry, counsel to the Company, to the effect that:

                           (i) ERSIC is a corporation duly organized, validly
                  existing and in good standing under the laws of the
                  jurisdiction in which it was organized and has all requisite
                  power and authority to conduct its business as it is currently
                  being conducted and to own, lease and operate its properties.
                  ERMA is a partnership duly organized, validly existing and in
                  good standing under the laws of the jurisdiction in which it
                  was organized and has all requisite power and authority to
                  conduct its business as it is currently being conducted and to
                  own, lease and operate its properties. ERSIC is duly qualified
                  as a foreign corporation authorized to transact business in
                  and is in good standing in each jurisdiction in which the
                  nature of its business or its ownership or leasing of property
                  requires such qualification, except where the failure to be so
                  qualified would not have a material adverse effect on the
                  business, prospects, operations, properties, net worth,
                  results of operations or financial condition of the Company
                  and the Subsidiaries considered as a whole.

                           (ii) All of the outstanding shares of capital stock
                  of, or other ownership interests in, each of ERSIC and ERMA
                  have been duly authorized and validly issued and, in the case
                  of shares of capital stock, are fully paid and non-assessable,
                  and all such shares and



                                      -44-





   45



                  other ownership interests owned of record by the Company or by
                  a Subsidiary of the Company are owned free and clear of any
                  perfected security interest and any lien, claim, encumbrance
                  or adverse interest of any nature.

                           (iii) Except as otherwise set forth in the
                  Prospectus, there are no pending legal or governmental
                  actions, suits or proceedings to which ERSIC or ERMA is a
                  party or of which any of their respective property is the
                  subject and which are required to be described in the
                  Registration Statement or the Prospectus, and, to the best of
                  such counsel's knowledge after due inquiry, no such actions,
                  suits or proceedings are threatened or contemplated, and no
                  contract or document of a character required to be described
                  in the Registration Statement or the Prospectus or to be filed
                  as an exhibit to the Registration Statement is not so
                  described or filed as required, and the descriptions of the
                  terms of any such contracts or documents contained in the
                  Registration Statement or the Prospectus are correct in all
                  material respects.

                           (iv) Neither ERSIC nor ERMA is (A) in violation of
                  its respective charter or by-laws, or other organizational
                  documents, or (B) in violation of any judgment, injunction,
                  order or decree of any court, governmental agency or body
                  (including, without limitation, any insurance regulatory
                  agency or body) or arbitrator having jurisdiction over ERSIC
                  or ERMA, or (C) in default in the performance of any
                  obligation, agreement or condition contained in any bond,
                  debenture, note or any other evidence of indebtedness or in
                  any other agreement, indenture, lease or instrument that, in
                  the case of either (B) or (C), is material to the business of
                  and the Other Subsidiaries.

                           (v) All material leases to which any of ERSIC or ERMA
                  is a party are valid and binding on each such subsidiary, as
                  the case may be, and no default has occurred or is continuing
                  thereunder, which might result in any material adverse change
                  in the business, prospects, financial condition or results of
                  operation of the Company and the Subsidiaries taken as a
                  whole.

                           (vi) Each of ERSIC and ERMA holds such licenses,
                  certificates, permits, franchises and authorizations from
                  insurance departments and other governmental or regulatory
                  authorities ("permits") (including, without limitation,
                  Insurance Licenses)



                                      -45-





   46



                  which are necessary to own, lease and operate its properties
                  and to conduct its business as described in the Prospectus,
                  except to the extent the failure to hold any such permits or
                  Insurance Licenses (either singularly or in the aggregate)
                  would not have a material adverse effect on the business,
                  prospects, operations, properties, net worth, results of
                  operations or financial condition of the Company and the
                  Subsidiaries taken as a whole; all such permits and the
                  Insurance Licenses are in full force and effect. Except as
                  disclosed in the Prospectus there has been, and there is no,
                  pending or threatened action, suit, proceeding, investigation
                  or event that could reasonably be expected to lead to the
                  revocation, termination, suspension or any other material
                  impairment of the rights of the holder of any such permit
                  (including, without limitation, the Insurance Licenses); such
                  permits and Insurance Licenses do not materially restrict the
                  conduct of business of the Other Subsidiaries except as
                  described in the Prospectus and except for any restrictions
                  customarily found in insurance licenses generally; and except
                  as disclosed in the Prospectus no insurance regulatory agency
                  or body has issued any order or decree impairing, restricting
                  or prohibiting the payment of dividends by any of the
                  Subsidiaries of the Company to its parent.

                           (vii) No relationship, direct or indirect, or
                  agreement, (including, without limitation, any voting
                  agreement), exists between or among any of ERSIC or ERMA and
                  any other party or any of their respective affiliates, which
                  is required by the Act to be described in the Registration
                  Statement or the Prospectus or to be filed as an exhibit to
                  the Registration Statement which is not described or filed as
                  required.

                  (h) You shall have received on the Closing Date and the Option
         Closing Date, as the case may be, an opinion, dated as of such date, of
         LeBoeuf, Lamb, Greene & MacRae, L.L.P., a partnership including
         professional corporations, as counsel for the Underwriters, with
         respect to the incorporation of the Company, the validity of the
         Shares, the Registration Statement, the Prospectus and other related
         matters as you may require, and the Company and Aetna shall have
         furnished to such counsel such documents as they reasonably request for
         the purpose of enabling them to pass upon such matters.



                                      -46-





   47



                  The opinions of Dewey Ballantine, counsel to the Company, of
Timothy Curry, counsel to ERI and ERSIC, of the counsel to Aetna and of LeBoeuf,
Lamb, Greene & MacRae, L.L.P., counsel to the Underwriters, described in

                  (i) No action shall have been taken and no statute, rule,
         regulation or order shall have been enacted, adopted or issued by any
         governmental agency as of such Closing Date or Option Closing Date, as
         the case may be, that would prevent the issuance of the Shares. No
         injunction, restraining order or order of any nature by a federal or
         state court of competent jurisdiction shall have been issued as of such
         Closing Date or Option Closing Date, as the case may be, that would
         prevent the issuance of the Shares.

                  (j) You shall have received a letter, dated the date of this
         Agreement, of Ernst & Young confirming that they are independent public
         accountants with respect to the Company within the meaning of the Act
         and the applicable published rules and regulations promulgated
         thereunder and stating in effect the information contained in Annex I.

                  (k) You shall have received a letter on and as of the Closing
         Date and the Option Closing Date from Ernst & Young substantially in
         the form and substance of, or confirming the statements contained in,
         the letter delivered to you by Ernst & Young on the date of this
         Agreement.

                  (l) The several obligations of the Underwriters to purchase
         Additional Shares hereunder are subject to the delivery to the
         Representatives on the Option Closing Date of such documents as you may
         reasonably request with respect to the good standing of the Company,
         the due authorization and issuance of the Additional Shares and other
         matters related to the issuance of the Additional Shares.

                  (m) All of the transactions contemplated by this Agreement and
         by the Registration Statement shall have been consummated at or prior
         to the time that the Shares are delivered and paid for pursuant to
         Section 4 of this Agreement.

                  (n) The Shares shall have been listed or approved for listing
         upon official notice of issuance on the New York Stock Exchange.



                                      -47-





   48



                  (o) The Company and Aetna shall have furnished or caused to be
         furnished to you such further certificates and documents as you shall
         have reasonably requested.

                  All such opinions, certificates, letters and other documents
will be in compliance with the provisions hereof only if they are reasonably
satisfactory in form and substance to you and your counsel.

                  Any certificate or document signed by any officer of the
Company or Aetna, as the case may be, and delivered to you, as the
Representatives, or to counsel for the Underwriters, shall be deemed a
representation and warranty by the Company or Aetna to each Underwriter as to
the statements made therein.

                  10. Effective Date of Agreement and Termination.

                  (a) This Agreement shall become effective upon the later of
         (i) execution of this Agreement and (ii) when notification of the
         effectiveness of the Registration Statement has been released by the
         Commission.

                  (b) This Agreement may be terminated at any time prior to the
         Closing Date or the Option Closing Date, as the case may be, by you by
         written notice to the Sellers if any of the following has occurred: (i)
         since the respective dates as of which information is given in the
         Registration Statement and the Prospectus, any material adverse change
         or development involving a prospective material adverse change in or
         affecting particularly the business, prospects, operations, properties,
         net worth, results of operations or financial condition of the Company
         or any Subsidiary other than Talcott Services Corporation, Executive
         Risk N.V. or Executive Risk Limited, whether or not arising in the
         ordinary course of business, which would, in your judgment, make it
         impracticable to market the Shares on the terms and in the manner
         contemplated in the Prospectus, (ii) any outbreak or escalation of
         hostilities or other national or international calamity or crisis or
         change in economic conditions or in the financial markets of the United
         States or elsewhere that, in your judgment, is material and adverse and
         would, in your judgment, make it impracticable to market the Shares on
         the terms and in the manner contemplated in the Prospectus, (iii) the
         suspension or material limitation of trading in securities on the NYSE,
         the American Stock Exchange or the NASDAQ National Market System or
         limitation on prices for securities on any such exchange or National
         Market System, (iv) the enactment, publication, decree or other
         promulgation of any federal or state statute, regulation, rule or order
         of any court or other governmental



                                      -48-





   49



         authority which in your opinion materially and adversely affects, or
         will materially and adversely affect, the business or operations of the
         Company or any Subsidiary other than Talcott Services Corporation,
         Executive Risk N.V. or Executive Risk Limited, (v) the declaration of a
         banking moratorium by either federal or New York State authorities or
         (vi) the taking of any action by any federal, state or local government
         or agency in respect of its monetary or fiscal affairs which in your
         opinion has a material adverse effect on the financial markets in the
         United States.

                  (c) If on the Closing Date or on the Option Closing Date, as
         the case may be, any one or more of the Underwriters shall fail or
         refuse to purchase the Firm Shares or Additional Shares, as the case
         may be, which it or they have agreed to purchase hereunder on such date
         and the aggregate number of Firm Shares or Additional Shares, as the
         case may be, which such defaulting Underwriter or Underwriters, as the
         case may be, agreed but failed or refused to purchase is not more than
         one-tenth of the total number of Shares to be purchased on such date by
         all Underwriters, each non-defaulting Underwriter shall be obligated
         severally, in the proportion which the number of Firm Shares set forth
         opposite its name in Schedule I bears to the total number of Firm
         Shares which all the non-defaulting Underwriters, as the case may be,
         have agreed to purchase, or in such other proportion as you may
         specify, to purchase the Firm Shares or Additional Shares, as the case
         may be, which such defaulting Underwriter or Underwriters, as the case
         may be, agreed but failed or refused to purchase on such date; provided
         that in no event shall the number of Firm Shares or Additional Shares,
         as the case may be, which any Underwriter has agreed to purchase
         pursuant to Section 2 hereof be increased pursuant to this Section 10
         by an amount in excess of one-ninth of such number of Firm Shares or
         Additional Shares, as the case may be, without the written consent of
         such Underwriter. If on the Closing Date or on an Option Closing Date,
         as the case may be, any Underwriter or Underwriters shall fail or
         refuse to purchase Firm Shares, or Additional Shares, as the case may
         be, and the aggregate number of Firm Shares or Additional Shares, as
         the case may be, with respect to which such default occurs is more than
         one-tenth of the aggregate number of Shares to be purchased on such
         date by all Underwriters and arrangements satisfactory to you and the
         applicable Sellers for purchase of such Shares are not made within 48
         hours after such default, this Agreement will terminate without
         liability on the part of any non-defaulting Underwriter and the
         applicable Sellers. In any such case which does not result in
         termination of this Agreement, either you or the Sellers



                                      -49-





   50



         shall have the right to postpone the Closing Date or the applicable
         Option Closing Date, as the case may be, but in no event for longer
         than seven days, in order that the required changes, if any, in the
         Registration Statement and the Prospectus or any other documents or
         arrangements may be effected. Any action taken under this paragraph
         shall not relieve any defaulting Underwriter from liability in respect
         of any default of any such Underwriter under this Agreement.

                  11. Agreements of Aetna. Aetna agrees with you and the Company
as follows:

                  (a) Aetna will deliver to you on or prior to the Closing Date
         a properly completed and executed United States Treasury Department
         Form W-9 (or other applicable form or statement specified by Treasury
         Department regulations in lieu thereof);

                  (b) Aetna will pay or cause to be paid all transfer taxes with
