            This GUARANTEE AGREEMENT (the "Series B Capital Securities
Guarantee"), dated as of             , 1997, is executed and delivered by
Executive Risk Inc., a Delaware insurance holding corporation (the "Guarantor"),
and The Chase Manhattan Bank, a New York banking corporation, as indenture
trustee (the "Capital Securities Guarantee Trustee"), for the benefit of the
Holders (as defined herein) from time to time of the Series B Capital Securities
(as defined herein) of Executive Risk Capital Trust, a Delaware statutory
business trust (the "Issuer").

            WHEREAS, pursuant to an Amended and Restated Declaration of Trust
(the "Declaration", which expression includes Annex I and Exhibits A-1, A-2, B
and C thereto), dated as of February 5, 1997, among the trustees of the Issuer,
the Guarantor, as sponsor, and the holders from time to time of undivided
beneficial interests in the assets of the Issuer, the Issuer issued on February
5, 1997 125,000 capital securities, having an aggregate liquidation amount of
$1,000 such capital securities being designated the 8.675% Series A Capital
Securities (the "Series A Capital Securities") and, in connection with an
Exchange Offer (as defined in the Declaration) is executing and delivering on
the date hereof this Series B Capital Securities Guarantee (as defined in the
Declaration) for the benefit of holders of the Series B Capital Securities (as
defined in the Declaration).

            WHEREAS, as incentive for the Holders to exchange their Series A
Capital Securities for an equal aggregate liquidation amount of the Series B
Capital Securities, the Guarantor desires irrevocably and unconditionally to
agree, to the extent set forth in this Series B Capital Securities Guarantee, to
pay to the Holders the Guarantee Payments (as defined below). The Guarantor
agrees to make certain other payments on the terms and conditions set forth
herein.

            WHEREAS, the Guarantor executed and delivered on February 5, 1997 a
guarantee agreement (the "Common Securities Guarantee"), with substantially
identical terms to this Series B Capital Securities Guarantee, for the benefit
of the holders of the Common Securities (as defined herein), except that if an
Event of Default (as defined in the Declaration) has occurred and is continuing,
the rights of holders of the Common Securities to receive Guarantee Payments
under the Common Securities Guarantee are subordinated, to the extent and in the
manner set forth in the Common Securities Guarantee, to the rights of holders of
Series A Capital Securities and the Series B Capital Securities to receive
Guarantee Payments under the Series A Capital Securities Guarantee and this
Series B Capital Securities Guarantee, as the case may be.
   5
            NOW, THEREFORE, in consideration of the exchange by each Holder of
its Series A Capital Securities for Series B Capital Securities, which exchange
the Guarantor hereby acknowledges shall benefit the Guarantor, the Guarantor
executes and delivers this Series B Capital Securities Guarantee for the benefit
of the Holders.

Guarantee Trustee, unless such defaults have been cured before the giving of

Guarantee Payment, the Capital Securities Guarantee Trustee shall be protected
in withholding such notice if and so long as the board of directors, the
executive committee, or a trust committee of directors and/or Responsible
Officers of the Capital Securities Guarantee Trustee in good faith determines
that the withholding of such notice is in the interests of the Holders.

            (b) The Capital Securities Guarantee Trustee shall not be deemed to

SECTION 2.8 Conflicting Interests

            The Declaration shall be deemed to be specifically described in this

   12
                                   ARTICLE III
                          POWERS, DUTIES AND RIGHTS OF
                      CAPITAL SECURITIES GUARANTEE TRUSTEE

SECTION 3.1 Powers and Duties of the Capital Securities Guarantee Trustee

            (a) This Series B Capital Securities Guarantee shall be held by the
Capital Securities Guarantee Trustee for the benefit of the Holders, and the
Capital Securities Guarantee Trustee shall not transfer this Series B Capital
Securities Guarantee to any Person except a Holder of Series B Capital
Securities exercising his or her rights pursuant to Section 5.4(b) or to a
Successor Capital Securities Guarantee Trustee on acceptance by such Successor
Capital Securities Guarantee Trustee of its appointment to act as Successor
Capital Securities Guarantee Trustee. The right, title and interest of the
Capital Securities Guarantee Trustee shall automatically vest in any Successor
Capital Securities Guarantee Trustee, and such vesting and succession of title
shall be effective whether or not conveyancing documents have been executed and
delivered pursuant to the appointment of such Successor Capital Securities
Guarantee Trustee.

            (b) If an Event of Default actually known to a Responsible Officer
of the Capital Securities Guarantee Trustee has occurred and is continuing, the
Capital Securities Guarantee Trustee shall enforce this Series B Capital
Securities Guarantee for the benefit of the Holders.

            (c) The Capital Securities Guarantee Trustee, before the occurrence
of any Event of Default and after the curing of all Events of Default that may
have occurred, shall undertake to perform only such duties as are specifically
set forth in this Series B Capital Securities Guarantee, and no implied
covenants shall be read into this Series B Capital Securities Guarantee against
the Capital Securities Guarantee Trustee. In case an Event of Default has
occurred (that has not been cured or waived pursuant to Section 2.6) and is
actually known to a Responsible Officer of the Capital Securities Guarantee
Trustee, the Capital Securities Guarantee Trustee shall exercise such of the
rights and powers vested in it by this Series B Capital Securities Guarantee,
and use the same degree of care and skill in its exercise thereof, as a prudent
person would exercise or use under the circumstances in the conduct of his or
her own affairs.

            (d) No provision of this Series B Capital Securities Guarantee shall
be construed to relieve the Capital Securities Guarantee Trustee from liability
for its own negligent action, its own negligent failure to act, or its own
willful misconduct, except that:
   13
            (i) prior to the occurrence of any Event of Default and after the
      curing or waiving of all such Events of Default that may have occurred:

                  (A) the duties and obligations of the Capital Securities
            Guarantee Trustee shall be determined solely by the express
            provisions of this Series B Capital Securities Guarantee, and the
            Capital Securities Guarantee Trustee shall not be liable except for
            the performance of such duties and obligations as are specifically
            set forth in this Series B Capital Securities Guarantee, and no
            implied covenants or obligations shall be read into this Series B
            Capital Securities Guarantee against the Capital Securities
            Guarantee Trustee; and

                  (B) in the absence of bad faith on the part of the Capital
            Securities Guarantee Trustee, the Capital Securities Guarantee
            Trustee may conclusively rely, as to the truth of the statements and
            the correctness of the opinions expressed therein, upon any
            certificates or opinions furnished to the Capital Securities
            Guarantee Trustee and conforming to the requirements of this Series
            B Capital Securities Guarantee; but in the case of any such
            certificates or opinions that by any provision hereof are
            specifically required to be furnished to the Capital Securities
            Guarantee Trustee, the Capital Securities Guarantee Trustee shall be
            under a duty to examine the same to determine whether or not they

            Guarantee;

            (ii) the Capital Securities Guarantee Trustee shall not be liable

      pertinent facts upon which such judgment was made;

            (iii) the Capital Securities Guarantee Trustee shall not be liable
      with respect to any action taken or omitted to be taken by it in good
      faith in accordance with the direction of the Holders of a Majority in
      liquidation amount of the Series B Capital Securities relating to the
      time, method and place of conducting any proceeding for any remedy
      available to the Capital Securities Guarantee Trustee, or exercising any
      trust or power conferred upon the Capital Securities Guarantee Trustee
      under this Series B Capital Securities Guarantee; and
   14
            (iv) no provision of this Series B Capital Securities Guarantee
      shall require the Capital Securities Guarantee Trustee to expend or risk
      its own funds or otherwise incur personal financial liability in the
      performance of any of its duties or in the exercise of any of its rights
      or powers, if the Capital Securities Guarantee Trustee shall have
      reasonable grounds for believing that the repayment of such funds or
      liability is not reasonably assured to it under the terms of this Series B
      Capital Securities Guarantee or indemnity, reasonably satisfactory to the
      Capital Securities Guarantee Trustee, against such risk or liability is
      not reasonably assured to it.

SECTION 3.2 Certain Rights of Capital Securities Guarantee Trustee

            (a)   Subject to the provisions of Section 3.1:

            (i) The Capital Securities Guarantee Trustee may conclusively rely,
      and shall be fully protected in acting or refraining from acting, upon any
      resolution, certificate, statement, instrument, opinion, report, notice,
      request, direction, consent, order, bond, debenture, note, other evidence
      of indebtedness or other paper or document believed by it to be genuine
      and to have been signed, sent or presented by the proper party or parties.

            (ii) Any direction or act of the Guarantor contemplated by this

      Officers' Certificate.

            (iii) Whenever, in the administration of this Series B Capital
      Securities Guarantee, the Capital Securities Guarantee Trustee shall deem
      it desirable that a matter be proved or established before taking,
      suffering or omitting any action hereunder, the Capital Securities
      Guarantee Trustee (unless other evidence is herein specifically
      prescribed) may, in the absence of bad faith on its part, request and
      conclusively rely upon an Officers' Certificate which, upon receipt of
      such request, shall be promptly delivered by the Guarantor.

            (iv) The Capital Securities Guarantee Trustee shall have no duty to
      see to any recording, filing or registration of any instrument (or any
      rerecording, refiling or registration thereof).

            (v) The Capital Securities Guarantee Trustee may consult with
      counsel of its selection, and the advice or opinion of such counsel with
      respect to legal
   15
      matters shall be full and complete authorization and protection in respect
      of any action taken, suffered or omitted by it hereunder in good faith and
      in accordance with such advice or opinion. Such counsel may be counsel to
      the Guarantor or any of its Affiliates and may include any of its
      employees. The Capital Securities Guarantee Trustee shall have the right
      at any time to seek instructions concerning the administration of this
      Series B Capital Securities Guarantee from any court of competent
      jurisdiction.

            (vi) The Capital Securities Guarantee Trustee shall be under no
      obligation to exercise any of the rights or powers vested in it by this
      Series B Capital Securities Guarantee at the request or direction of any
      Holder, unless such Holder shall have provided to the Capital Securities
      Guarantee Trustee such security and indemnity, reasonably satisfactory to
      the Capital Securities Guarantee Trustee, against the costs, expenses
      (including attorneys' fees and expenses and the expenses of the Capital
      Securities Guarantee Trustee's agents, nominees or custodians) and
      liabilities that might be incurred by it in complying with such request or
      direction, including such reasonable advances as may be requested by the
      Capital Securities Guarantee Trustee; provided that, nothing contained in
      this Section 3.2(a)(vi) shall be taken to relieve the Capital Securities
      Guarantee Trustee, upon the occurrence of an Event of Default, of its
      obligation to exercise the rights and powers vested in it by this Series B
      Capital Securities Guarantee.

            (vii) The Capital Securities Guarantee Trustee shall not be bound to
      make any investigation into the facts or matters stated in any resolution,

      investigation into such facts or matters as it may see fit.

            (viii) The Capital Securities Guarantee Trustee may execute any of
      the trusts or powers hereunder or perform any duties hereunder either
      directly or by or through agents, nominees, custodians or attorneys, and
      the Capital Securities Guarantee Trustee shall not be responsible for any
      misconduct or negligence on the part of any agent or attorney appointed
      with due care by it hereunder.

            (ix) Any action taken by the Capital Securities Guarantee Trustee or
      its agents hereunder shall bind
   16
      the Holders, and the signature of the Capital Securities Guarantee Trustee
      or its agents alone shall be sufficient and effective to perform any such
      action. No third party shall be required to inquire as to the authority of
      the Capital Securities Guarantee Trustee to so act or as to its compliance
      with any of the terms and provisions of this Series B Capital Securities
      Guarantee, both of which shall be conclusively evidenced by the Capital
      Securities Guarantee Trustee's or its agent's taking such action.

            (x) Whenever in the administration of this Series B Capital
      Securities Guarantee the Capital Securities Guarantee Trustee shall deem
      it desirable to receive instructions with respect to enforcing any remedy
      or right or taking any other action hereunder, the Capital Securities
      Guarantee Trustee (i) may request instructions from the Holders of a
      Majority in liquidation amount of the Series B Capital Securities, (ii)
      may refrain from enforcing such remedy or right or taking such other
      action until such instructions are received, and (iii) shall be protected

      or within the discretion or rights or powers conferred upon it by this
      Series B Capital Securities Guarantee.

            (b) No provision of this Series B Capital Securities Guarantee shall
be deemed to impose any duty or obligation on the Capital Securities Guarantee
Trustee to perform any act or acts or exercise any right, power, duty or
obligation conferred or imposed on it in any jurisdiction in which it shall be
illegal, or in which the Capital Securities Guarantee Trustee shall be
unqualified or incompetent in accordance with applicable law, to perform any
such act or acts or to exercise any such right, power, duty or obligation. No
permissive power or authority available to the Capital Securities Guarantee
Trustee shall be construed to be a duty.

      authority. If such corporation publishes reports of condition at least
      annually, pursuant to law or to the requirements of the supervising or
      examining authority referred to above, then, for the purposes of this
      Section 4.1(a)(ii), the combined capital and surplus of such corporation
      shall be deemed to be its combined capital and surplus as set forth in its
      most recent report of condition so published.

except during an Event of Default.
   18

Trustee has been appointed and has accepted such appointment by written
instrument executed by such Successor Capital Securities Guarantee Trustee and
delivered to the Guarantor.

            (c) The Capital Securities Guarantee Trustee shall hold office until
a Successor Capital Securities Guarantee Trustee shall have been appointed or
until its removal or resignation. The Capital Securities Guarantee Trustee may
resign from office (without need for prior or subsequent accounting) by an
instrument in writing executed by the Capital Securities Guarantee Trustee and
delivered to the Guarantor, which resignation shall not take effect until a
Successor Capital Securities Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Capital Securities Guarantee Trustee and delivered to the Guarantor and the
resigning Capital Securities Guarantee Trustee.

            (d) If no Successor Capital Securities Guarantee Trustee shall have

Trustee.

acts or omissions to act of any Successor Capital Securities Guarantee Trustee.

on a subordinated basis to the extent set forth in this Series B Capital
Securities Guarantee to the Holders the Guarantee Payments (without duplication
of amounts theretofore paid by the Issuer), as and when due,
   19
regardless of any defense, right of set-off or counterclaim that the Issuer may
have or assert. The Guarantor's obligation to make a Guarantee Payment may be
satisfied by direct payment of the required amounts by the Guarantor to the
Holders or by causing the Issuer to pay such amounts to the Holders.

SECTION 5.2 Waiver of Notice and Demand

            The Guarantor hereby waives notice of acceptance of this Series B
Capital Securities Guarantee and of any liability to which it applies or may
apply, presentment, demand for payment, any right to require a proceeding first
against the Issuer or any other Person before proceeding against the Guarantor,
protest, notice of nonpayment, notice of dishonor, notice of redemption and all
other notices and demands.

SECTION 5.3 Obligations Not Affected

            The obligations, covenants, agreements and duties of the Guarantor
under this Series B Capital Securities Guarantee shall in no way be affected or
impaired by reason of the happening from time to time of any of the following:

            (a) the release or waiver, by operation of law or otherwise, of the
performance or observance by the Issuer of any express or implied agreement,
covenant, term or condition relating to the Series B Capital Securities to be
performed or observed by the Issuer;

            (b) the extension of time for the payment by the Issuer of all or
any portion of the Distributions, Redemption Price, Liquidation Distribution or
any other sums payable under the terms of the Series B Capital Securities or the
extension of time for the performance of any other obligation under, arising out
of, or in connection with, the Series B Capital Securities (other than an
extension of time for payment of Distributions, Redemption Price, Liquidation
Distribution or other sum payable that results from the extension of any
interest payment period on the Debentures permitted by the Indenture);

            (c) any failure, omission, delay or lack of diligence on the part of
the Holders to enforce, assert or exercise any right, privilege, power or remedy
conferred on the Holders pursuant to the terms of the Series B Capital
Securities, or any action on the part of the Issuer granting indulgence or
extension of any kind;

            (d) the voluntary or involuntary liquidation, dissolution, sale of
any collateral, receivership, insolvency, bankruptcy, assignment for the benefit
of creditors, reorganization, arrangement, composition or
   20
readjustment of debt of, or other similar proceedings affecting, the Issuer or
any of the assets of the Issuer;

            (e) any invalidity of, or defect or deficiency in, the Series B
Capital Securities;

            (f) the settlement or compromise of any obligation guaranteed hereby
or hereby incurred; or

            (g) any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a guarantor, it being
the intent of this Section 5.3 that the obligations of the Guarantor with
respect to the Guarantee Payments shall be absolute and unconditional under any
and all circumstances.

            There shall be no obligation of the Holders to give notice to, or
obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

SECTION 5.4 Rights of Holders

            (a) The Holders of a Majority in liquidation amount of the Series B
Capital Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Capital Securities
Guarantee Trustee in respect of this Series B Capital Securities Guarantee or
exercising any trust or power conferred upon the Capital Securities Guarantee
Trustee under this Series B Capital Securities Guarantee.

            (b) If the Capital Securities Guarantee Trustee fails to enforce
such Series B Capital Securities Guarantee, any Holder of Series B Capital
Securities may institute a legal proceeding directly against the Guarantor to
enforce the Capital Securities Guarantee Trustee's rights under this Series B
Capital Securities Guarantee, without first instituting a legal proceeding
against the Issuer, the Capital Securities Guarantee Trustee or any other person
or entity. The Guarantor waives any right or remedy to require that any action
be brought first against the Issuer or any other person or entity before
proceeding directly against the Guarantor.

            This Series B Capital Securities Guarantee creates a guarantee of
payment and not of collection.

SECTION 5.6  Subrogation

            The Guarantor shall be subrogated to all (if any) rights of the
Holders against the Issuer in respect of any amounts paid to such Holders by the
Guarantor under this
   21
Series B Capital Securities Guarantee; provided, however, that the Guarantor
shall not (except to the extent required by mandatory provisions of law) be
entitled to enforce or exercise any right that it may acquire by way of
subrogation or any indemnity, reimbursement or other agreement, in all cases as
a result of payment under this Series B Capital Securities Guarantee, if, at the
time of any such payment, any amounts are due and unpaid under this Series B
Capital Securities Guarantee. If any amount shall be paid to the Guarantor in
violation of the preceding sentence, the Guarantor agrees to hold such amount in
trust for the Holders and to pay over such amount to the Holders.

SECTION 5.7 Independent Obligations

            The Guarantor acknowledges that its obligations hereunder are
independent of the obligations of the Issuer with respect to the Series B
Capital Securities, and that the Guarantor shall be liable as principal and as
debtor hereunder to make Guarantee Payments pursuant to the terms of this Series
B Capital Securities Guarantee notwithstanding the occurrence of any event
referred to in subsections (a) through (h), inclusive, of Section 5.3 hereof.

SECTION 5.8 Possibility of Advancement of Maturity Date of Debentures

            The parties hereto acknowledge that the Maturity Date (as defined in
the Indenture) of the Debentures may be advanced pursuant to the provisions of
Section 14.06 of the Indenture.

Guarantor's capital stock (which includes common and preferred stock) or (ii)
make any payment of principal, interest or premium, if any, with respect to, or
repay or repurchase or redeem any debt securities of the Guarantor (including
any Other Debentures) that rank pari passu with or junior in right of payment to
the Debentures or (iii) make any guarantee payments with respect to any
guarantee by the Guarantor of the debt securities of any subsidiary of the
Guarantor (including Other Guarantees) if such guarantee ranks pari passu with
or junior in right of payment to the Debentures (other than (a) dividends or
distributions in
   22
shares of, or options, warrants or rights to subscribe for or purchase shares
of, common stock of the Guarantor, (b) any declaration of a dividend in
connection with the implementation of a stockholders' rights plan, or the
issuance of stock under any such plan in the future, or the redemption or
repurchase of any such rights pursuant thereto, (c) payments under the Capital
Securities Guarantee, (d) as a result of a reclassification of the Guarantor's
capital stock or the exchange or the conversion of one class or series of the
Guarantor's capital stock for another class or series of the Guarantor's capital
stock, (e) the purchase of fractional interests in shares of the Guarantor's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged, (f) the issuance of Common
Stock upon exercise of the Aetna Option and (g) purchases or issuances of common
stock in connection with any of the Guarantor's stock option, stock purchase,
stock loan or other benefit plans for its directors, officers or employees or
any of the Guarantor's dividend reinvestment plans, in each case as now existing
or hereafter established or amended), if at such time (i) there shall have
occurred any event of which the Guarantor has actual knowledge that (a) is, or
with the giving of notice or the lapse of time, or both, would be an Event of
Default and (b) in respect of which the Guarantor shall not have taken
reasonable steps to cure, (ii) if such Debentures are held by the Property
Trustee, the Guarantor shall be in default with respect to its payment of any
obligations under this Series B Capital Securities Guarantee or (iii) the
Guarantor shall have given notice of its election of the exercise of its right
to extend the interest payment period pursuant to Section 16.01 of the Indenture
and any such extension shall be continuing.

SECTION 6.2 Ranking

            This Series B Capital Securities Guarantee will constitute an
unsecured obligation of the Guarantor and will rank (i) subordinate and junior
in right of payment to Senior Indebtedness (as defined in the Indenture), to the
same extent and in the same manner that the Debentures are subordinated to
Senior Indebtedness pursuant to the Indenture (except as indicated below), it
being understood that the terms of Article XV of the Indenture shall apply to
the obligations of the Guarantor under this Series B Capital Securities
Guarantee as if (x) such Article XV were set forth herein in full and (y) such
obligations were substituted for the term "Securities" appearing in such Article
XV, except that with respect to Section 15.03 of the Indenture only, insofar as
such section relates to bankruptcy or insolvency proceedings only, the term
"Senior Indebtedness" shall mean all liabilities of the Guarantor, whether or
not for money borrowed (other than obligations in respect of Other Guarantees),
(ii) pari passu with any Other
   23
Guarantee (as defined herein) and any Other Common Securities Guarantee and
(iii) senior to any obligations in respect of any class of the Guarantor's
capital stock.

no further force and effect (i) upon full payment of the Redemption Price (as
defined in the Declaration) of all Series B Capital Securities, or (ii) upon
liquidation of the Issuer, the full payment of the amounts payable in accordance
with the Declaration or the distribution of the Debentures to the Holders of all
the Series B Capital Securities. Notwithstanding the foregoing, this Series B
Capital Securities Guarantee will continue to be effective or will be
reinstated, as the case may be, if at any time any Holder of Series B Capital
Securities must restore payment of any sums paid under the Series B Capital
Securities or under this Series B Capital Securities Guarantee.

                                  ARTICLE VIII
                                 INDEMNIFICATION

SECTION 8.1 Exculpation

            (a) No Indemnified Person shall be liable, responsible or
accountable in damages or otherwise to the Guarantor or any Covered Person for
any loss, damage or claim incurred by reason of any act or omission performed or
omitted by such Indemnified Person in good faith in accordance with this Series
B Capital Securities Guarantee and in a manner that such Indemnified Person
reasonably believed to be within the scope of the authority conferred on such
Indemnified Person by this Series B Capital Securities Guarantee or by law,

claim incurred by reason of such Indemnified Person's negligence or willful

good faith upon the records of the Guarantor and upon such information,
opinions, reports or statements presented to the Guarantor by any Person as to
matters the Indemnified Person reasonably believes are within such other

reasonable care by or on behalf of the Guarantor, including information,

pertinent to the existence and amount of assets from which Distributions to
Holders might properly be paid.

SECTION 8.2 Indemnification

            The Guarantor agrees to indemnify each Indemnified Person for, and
to hold each Indemnified Person harmless against, any and all loss, liability,
damage, claim or expense incurred without negligence or bad faith on its part,
arising out of or in connection with the acceptance or administration of the
trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against, or
investigating, any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder. The obligation to
indemnify as set forth in this Section 8.2 shall survive the termination of this
Series B Capital Securities Guarantee or the earlier resignation or removal of
the Capital Securities Guarantee Trustee.

the prior approval of the Holders of a Majority in liquidation amount of the
Securities (including the stated amount that would be paid on redemption,
