         Markel  Capital Trust I, a statutory  business  trust created under the
laws of the State of Delaware (the "Trust"),  hereby offers,  upon the terms and
subject  to the  conditions  set  forth in this  Prospectus  (as the same may be
amended  or  supplemented  from  time  to  time,  the  "Prospectus")  and in the
accompanying  Letter of  Transmittal  (which  together  constitute the "Exchange
Offer"),  to exchange up to  $150,000,000  aggregate  Liquidation  Amount of its
8.71% Series B Capital Securities (the "New Capital Securities") which have been
registered under the Securities Act of 1933, as amended (the "Securities  Act"),
pursuant  to  a  Registration  Statement  (as  defined  herein)  of  which  this
Prospectus  constitutes a part, for a like Liquidation Amount of its outstanding
8.71%  Series A Capital  Securities  (the "Old  Capital  Securities"),  of which
$150,000,000  aggregate  Liquidation  Amount  is  outstanding.  Pursuant  to the
Exchange Offer, Markel Corporation,  a Virginia corporation (the "Company"),  is
also  offering to exchange (i) its  guarantee of payments of cash  distributions
and  payments  on  liquidation  of the Trust or  redemption  of the Old  Capital
Securities  (the "Old  Guarantee")  for a like  guarantee  in respect of the New
Capital  Securities  (the "New  Guarantee")  and (ii) all of its 8.71%  Series A
Junior Subordinated Deferrable Interest Debentures due January 1, 2046 (the "Old
Junior  Subordinated  Debentures") for a like aggregate  principal amount of its
8.71% Series B Junior Subordinated Deferrable Interest Debentures due January 1,
2046 (the "New Junior  Subordinated  Debentures"),  which New  Guarantee and New
Junior  Subordinated  Debentures also have been registered  under the Securities
Act.  The  Old  Capital  Securities,  the  Old  Guarantee  and  the  Old  Junior
Subordinated  Debentures  are  collectively  referred  to  herein  as  the  "Old
Securities" and the New Capital Securities, the New Guarantee and the New Junior
Subordinated  Debentures  are  collectively  referred  to  herein  as  the  "New
Securities."

         The terms of the New Securities are identical in all material  respects
to the respective  terms of the Old  Securities,  except that the New Securities
have been registered  under the Securities Act and therefore will not be subject
to certain  restrictions on transfer  applicable to the Old Securities,  the New
Capital  Securities  will not contain the $100,000  minimum  Liquidation  Amount
transfer  restriction,  the New  Capital  Securities  will not  provide  for any
increase  in  the  Distribution  rate  thereon,   the  New  Junior  Subordinated
Debentures  will not contain the  $100,000  minimum  principal  amount  transfer
restriction and (e) the New Junior Subordinated  Debentures will not provide for
any increase in the interest rate thereon.  See  "Description of New Securities"
and  "Description  of Old  Securities."  The New  Capital  Securities  are being
offered for exchange in order to satisfy certain  obligations of the Corporation
and the Trust under the  Registration  Rights  Agreement dated as of January 13,
1997 (the "Registration Rights Agreement") among the Corporation,  the Trust and
the Initial Purchasers (as defined herein). In the event that the Exchange Offer
is  consummated,  any Old Capital  Securities  which  remain  outstanding  after
consummation of the Exchange Offer and the New Capital  Securities issued in the
Exchange  Offer will vote together as a single class for purposes of determining
whether holders of the requisite  percentage in outstanding  Liquidation  Amount
thereof have taken certain  actions or exercised  certain rights under the Trust
Agreement.

                                              (CONTINUED ON THE FOLLOWING PAGE)

         This Prospectus and the Letter of Transmittal are first being mailed to
all holders of Old Capital Securities on , 1997.

SECURITIES IN THE EXCHANGE OFFER.

  THESE  SECURITIES  HAVE NOT  BEEN APPROVED OR DISAPPROVED BY THE SECURITIES
         AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR
            HAS THE SECURITIES AND EXCHANGE COMMISSION OR ANY STATE
             SECURITIES COMMISSION PASSED UPON THE ACCURACY OR AD-
                 EQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION
                     TO THE CONTRARY IS A CRIMINAL OFFENSE.

               The date of this Prospectus is _________ __, 1997.


<PAGE>


         The  New   Capital   Securities   and  the   Old   Capital   Securities
(collectively,  the "Capital Securities")  represent beneficial interests in the
assets of the  Trust.  The  Corporation  is the  owner of all of the  beneficial
interests   represented   by  common   securities  of  the  Trust  (the  "Common
Securities," and together with the Capital Securities,  the "Trust Securities").
The Chase  Manhattan  Bank is the Property  Trustee of the Trust.  The Trust was
formed for the sole purpose of issuing the Trust  Securities  and  investing the
proceeds thereof in the Junior Subordinated  Debentures (as defined herein). The
Junior  Subordinated  Debentures  will  mature on January  1, 2046 (the  "Stated
Maturity Date").  The Capital  Securities will have a preference over the Common
Securities under certain  circumstances  with respect to cash  distributions and
amounts payable on liquidation, redemption or otherwise. See "Description of New
Securities--Subordination of Common Securities."

         As used  herein,  (i)  "Indenture"  means  the  Indenture,  dated as of
January 13, 1997,  as amended and  supplemented  from time to time,  between the
Corporation and The Chase  Manhattan Bank, as Debenture  Trustee (the "Debenture
Trustee"),  and (ii) "Declaration" means the Amended and Restated Declaration of
Trust  relating  to the  Trust  among the  Corporation,  as  Sponsor,  The Chase
Manhattan Bank as Property Trustee (the "Property Trustee"), Chase Manhattan
Bank  Delaware,  as  Delaware  Trustee,   (the  "Delaware  Trustee"),   and  the
Administrative  Trustees named therein (collectively,  with the Property Trustee
and Delaware Trustee,  the "Issuer Trustees").  In addition,  as the context may
require,  unless otherwise  expressly stated, (i) the term "Capital  Securities"
includes the Old Capital  Securities  and the New Capital  Securities,  (ii) the
term  "Trust  Securities"   includes  the  Capital  Securities  and  the  Common
Securities,  (iii) the term "Junior  Subordinated  Debentures"  includes the Old
Junior Subordinated  Debentures and the New Junior  Subordinated  Debentures and
(iv) the term "Guarantee" includes the Old Guarantee and the New Guarantee.

         Holders  of the New  Capital  Securities  will be  entitled  to receive
cumulative cash  distributions,  accumulating  from January 13, 1997 and payable
semi-annually  in arrears on January 1 and July 1 of each year,  commencing July
1, 1997, at the annual rate of 8.71% of the Liquidation Amount of $1,000 per New
Capital Security ("Distributions"). So long as no Debenture Event of Default (as
defined herein) has occurred and is continuing,  the Company will have the right
to defer payments of interest on the Junior Subordinated  Debentures at any time
and from time to time for a period  not  exceeding  10  consecutive  semi-annual
periods with respect to each  deferral  period (each,  an  "Extension  Period"),
provided that no Extension  Period may extend beyond the Stated  Maturity  Date.
Upon the termination of any such Extension Period and the payment of all amounts
then due, the Company may elect to begin a new Extension Period,  subject to the
requirements set forth in the Indenture. If and for so long as interest payments
on the Junior  Subordinated  Debentures  are so deferred,  Distributions  on the
Trust  Securities  will also be deferred and the Company will not be  permitted,
subject  to  certain  exceptions  described  herein,  to declare or pay any cash
distributions with respect to the Company's capital stock (which includes common
and preferred  stock) or to make any payment with respect to debt  securities of
the  Company  that rank pari  passu  with or junior to the  Junior  Subordinated
Debentures.  During an  Extension  Period,  interest on the Junior  Subordinated
Debentures  will  continue to accrue (and the amount of  Distributions  to which
holders of the Trust Securities are entitled will continue to accumulate) at the
rate of  8.71%  per  annum,  compounded  semi-annually,  and  holders  of  Trust
Securities  will be required to accrue interest income for United States federal
income tax  purposes.  See  "Description  of Junior  Subordinated  Debentures --
Option  to Extend  Interest  Payment  Date"  and  "Certain  Federal  Income  Tax
Consequences -- Interest Income and Original Issue Discount."

         The  Company,   through  the  Guarantee,   the  Common  Guarantee,  the
Declaration,  the Junior  Subordinated  Debentures  and the  Indenture  (each as
defined herein), taken together, has guaranteed,  or will guarantee, as the case
may be, fully,  irrevocably and  unconditionally  all of the Trust's obligations
under the Trust Securities.  See "Relationship Among the New Capital Securities,
the  New  Junior  Subordinated  Debentures  and the New  Guarantee  -- Full  and
Unconditional  Guarantee." The Old Guarantee and the Common Guarantee  currently
guarantee,  and the New Guarantee will guarantee,  payments of Distributions and
payments on liquidation or redemption of the Trust Securities,  but in each case
only to the extent that the Trust holds funds on hand legally available therefor
and has failed to make such payments,  as described herein.  See "Description of
the  Guarantee."  If the Company fails to make a required  payment on the Junior
Subordinated  Debentures,  the Trust will not have sufficient  funds to make the
related  payments,  including  Distributions,   on  the  Trust  Securities.  The
Guarantee  and the Common  Guarantee  will not cover any such  payment  when the
Trust does not have sufficient funds on hand legally available therefor. In such
event, a holder of Capital Securities may institute a legal proceeding  directly
against  the  Company to enforce  its  rights in  respect of such  payment.  See
"Description  of New Junior  Subordinated  Debentures --  Enforcement of Certain
Rights by Holders of Capital  Securities."  The obligations of the Company under
the  Guarantee  and the Junior  Subordinated  Debentures  will be unsecured  and
subordinate and rank junior in right of payment to all Senior  Indebtedness  (as
defined   in   "Description   of   New   Junior   Subordinated   Debentures   --
Subordination"),  which  totaled  approximately  $120.3  million at December 31,
1996.

         The Trust Securities will be subject to mandatory  redemption in a Like
Amount (as defined herein), (i) in whole but not in part, on the Stated Maturity
Date upon repayment of the Junior Subordinated  Debentures at a redemption price
equal  to the  principal  amount  of,  plus  accrued  interest  on,  the  Junior
Subordinated Debentures (the "Maturity Redemption Price"), (ii) in whole but not
in part,  at any time,  contemporaneously  with the optional  prepayment  of the
Junior Subordinated Debentures upon the occurrence and continuation of a Special
Event (as defined  herein),  at a  redemption  price equal to the Special  Event
Prepayment Price (as defined herein) (the "Special Event Redemption Price"), and
(iii) in whole or in part, on or after January 1, 2007,  contemporaneously  with
the optional prepayment by the Company of the Junior Subordinated Debentures, at
a redemption  price equal to the Optional  Prepayment  Price (as defined herein)
(the "Optional  Redemption  Price").  Any of the Maturity  Redemption Price, the
Special Event Redemption Price and the Optional Redemption Price may be referred
to herein as the  "Redemption  Price." See  "Description  of New  Securities  --
Redemption."



<PAGE>


         The New Junior Subordinated  Debentures will be prepayable prior to the
Stated  Maturity  Date at the option of the Company  (i) on or after  January 1,
2007,  in whole or in part,  at a  prepayment  price (the  "Optional  Prepayment
Price")  equal to 104.355% of the principal  amount  thereof on January 1, 2007,
declining  ratably on each January 1 thereafter  to 100% on or after  January 1,
2017, plus accrued interest thereon to the date of prepayment,  or (ii) prior to
January 1, 2007, in whole but not in part, upon the occurrence and  continuation
of a Special Event, at a prepayment price (the "Special Event Prepayment Price")
equal to the greater of (a) 100% of the principal amount thereof or (b) the sum,
as determined by a Quotation Agent (as defined herein), of the present values of
the principal amount and premium payable with respect to an optional  redemption
of New  Junior  Subordinated  Debentures  on  January  1,  2007,  together  with
scheduled  payments of interest on the New Junior  Subordinated  Debentures from
the  prepayment  date  to and  including  January  1,  2007,  discounted  to the
prepayment  date on a semi-annual  basis  (assuming a 360-day year consisting of
twelve 30-day months) at the Adjusted Treasury Rate (as defined herein) plus, in
either case,  accrued interest thereon to the date of prepayment.  Either of the
Optional  Prepayment Price or the Special Event Prepayment Price may be referred
to herein as the "Prepayment Price." See "Description of New Junior Subordinated
Debentures  --  Optional  Prepayment"  and " --  Conditional  Right  to  Advance
Maturity and Special Event Prepayment."

         The Company will have the right at any time to terminate  the Trust and
cause a Like Amount of the Junior  Subordinated  Debentures to be distributed to
the holders of the Trust Securities in liquidation of the Trust,  subject to the
Company  having  received  an  opinion  of  counsel  to  the  effect  that  such
distribution  will not be a taxable event to holders of the Capital  Securities.
Unless the Junior Subordinated  Debentures are distributed to the holders of the
Trust  Securities,  in the event of a  liquidation  of the Trust  under  certain
circumstances  described herein,  after satisfaction of liabilities to creditors
of the  Trust  as  required  by  applicable  law,  the  holders  of the  Capital
Securities  generally will be entitled to receive a Liquidation Amount of $1,000
per Capital  Security plus accumulated and unpaid  Distributions  thereon to the
date of payment.  See "Description of New Securities -- Liquidation of the Trust
and Distribution of Junior Subordinated  Debentures" and "Certain Federal Income
Tax  Consequences  -- Receipt  of Junior  Subordinated  Debentures  or Cash Upon
Liquidation of the Trust."

         The Trust is making the Exchange Offer of the New Capital Securities in
reliance on the position of the staff of the Division of Corporation  Finance of
the  Securities  and  Exchange  Commission  (the  "Commission")  as set forth in
certain  interpretive  letters addressed to third parties in other transactions.
However,  neither  the  Company  nor the Trust has sought  its own  interpretive
letter  and  there  can be no  assurance  that  the  staff  of the  Division  of
Corporation  Finance of the Commission would make a similar  determination  with
respect to the Exchange  Offer as it has in such  interpretive  letters to third
parties.  Based  on  these  interpretations  by the  staff  of the  Division  of
Corporation  Finance  of the  Commission,  and  subject  to the two  immediately
following  sentences,  the  Company  and the  Trust  believe  that  New  Capital
Securities  issued  pursuant to this Exchange  Offer in exchange for Old Capital
Securities  may be offered for resale,  resold and  otherwise  transferred  by a
holder  thereof  (other than a holder who is a  broker-dealer)  without  further
compliance with the  registration  and prospectus  delivery  requirements of the
Securities  Act,  provided that such New Capital  Securities are acquired in the
ordinary  course  of  such  holder's  business  and  that  such  holder  is  not
participating,  and has no  arrangement  or  understanding  with any  person  to
participate,  in a distribution  (within the meaning of the  Securities  Act) of
such New Capital Securities.  However,  any holder of Old Capital Securities who
is an  "affiliate"  of the Company or the Trust or who intends to participate in
the Exchange Offer for the purpose of distributing  New Capital  Securities,  or
any broker-dealer who purchased Old Capital  Securities from the Trust to resell
pursuant  to Rule  144A  under the  Securities  Act  ("Rule  144A") or any other
available  exemption  under the Securities  Act, (a) will not be able to rely on
the  interpretations of the staff of the Division of Corporation  Finance of the
Commission set forth in the above-mentioned  interpretive  letters, (b) will not
be permitted or entitled to tender such Old Capital  Securities  in the Exchange
Offer  and (c)  must  comply  with  the  registration  and  prospectus  delivery
requirements of the Securities Act in connection with any sale or other transfer
of such Old Capital Securities unless such sale is made pursuant to an exemption
from such  requirements.  In addition,  as described below, if any broker-dealer
holds  Old  Capital  Securities  acquired  for its own  account  as a result  of
market-making  or other  trading  activities  and  exchanges  such  Old  Capital
Securities for New Capital  Securities,  then such  broker-dealer must deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resales of such New Capital Securities.

         Each  holder of Old  Capital  Securities  who  wishes to  exchange  Old
Capital  Securities  for New Capital  Securities  in the Exchange  Offer will be
required to represent  that (i) it is not an  "affiliate"  of the Company or the
Trust,  (ii) any New Capital  Securities to be received by it are being acquired
in the  ordinary  course  of its  business,  (iii)  it  has  no  arrangement  or
understanding  with any person to  participate  in a  distribution  (within  the
meaning of the Securities Act) of such New Capital Securities,  and (iv) if such
holder is not a  broker-dealer,  such  holder is not  engaged  in,  and does not
intend to engage in, a distribution  (within the meaning of the Securities  Act)
of such New  Capital  Securities.  In  addition,  the  Company and the Trust may
require such holder, as a condition to such holder's  eligibility to participate
in the  Exchange  Offer,  to furnish to the  Company  and the Trust (or an agent
thereof) in writing  information as to the number of "beneficial owners" (within
the meaning of Rule 13d-3 under the Securities Exchange Act of 1934, as amended)
on behalf of whom such holder  holds the Capital  Securities  to be exchanged in
the Exchange Offer. Each  broker-dealer that receives New Capital Securities for
its own account pursuant to the Exchange Offer must acknowledge that it acquired
the Old Capital  Securities  for its own account as the result of  market-making
activities  or other  trading  activities  and must agree that it will deliver a
prospectus meeting the requirements of the Securities Act in connection with any
resale of such New Capital Securities.  The Letter of Transmittal states that by
so  acknowledging  and by delivering a prospectus,  a broker-dealer  will not be
deemed to admit that it is an "underwriter" within the meaning of the Securities
Act.  Based on the position  taken by the staff of the  Division of  Corporation
Finance of the Commission in the  interpretive  letters  referred to above,  the
Company and the Trust  believe  that  broker-dealers  who  acquired  Old Capital
Securities for their own accounts,  as a result of  market-making  activities or
other trading  activities  ("Participating  Broker-Dealers"),  may fulfill their
prospectus  delivery  requirements  with  respect to the New Capital  Securities
received  upon exchange of such Old Capital  Securities  (other than Old Capital
Securities which represent an unsold allotment from the original sale of the Old
Capital Securities) with a prospectus meeting the requirements of the Securities
Act, which may be the prospectus prepared for an exchange offer so long as it
contains a description of the plan of distribution with respect to the resale of
such New Capital Securities.  Accordingly, this Prospectus, as it may be amended
or supplemented from time to time, may be used by a Participating Broker-Dealer
during the period referred to below in connection with resales of New Capital
Securities received in exchange for Old Capital Securities where such Old
Capital Securities were acquired by such Participating Broker-Dealer for its own
account as a result of market-making or other trading activities.  Subject to
certain provisions set forth in the Registration Rights Agreement, the Company
and the Trust have agreed that this Prospectus, as it may be amended or
supplemented from time to time, may be used by a Participating Broker- Dealer in

<PAGE>


connection with resales of such New Capital Securities for a period ending 90
days after the Expiration Date (as defined herein) (subject to extension under
certain limited circumstances described below) or, if earlier, when all such New
Capital Securities have been disposed of by such Participating Broker-Dealer.
See "Plan of Distribution."  However, a Participating Broker-Dealer who intends
to use this Prospectus in connection with the resale of New Capital Securities
received in exchange for Old Capital Securities pursuant to the Exchange Offer
must notify the Company or the Trust, or cause the Company or the Trust to be
notified, on or prior to the Expiration Date, that it is a Participating
Broker-Dealer.  Such notice may be given in the space provided for that purpose
in the Letter of Transmittal or may be delivered to the Exchange Agent at one of
the addresses set forth herein under "The Exchange Offer--Exchange Agent."  Any
Participating Broker-Dealer who is an "affiliate" of the Company or the Trust
may not rely on such interpretive letters and must comply with the registration
and prospectus delivery requirements of the Securities Act in connection with
any resale transaction.  See "The Exchange Offer--Resales of New Capital
Securities."

         In that regard,  each  Participating  Broker-Dealer  who surrenders Old
Capital Securities pursuant to the Exchange Offer will be deemed to have agreed,
by execution of the Letter of Transmittal, that, upon receipt of notice from the
Company or the Trust of the occurrence of any event or the discovery of any fact
which  makes any  statement  contained  or  incorporated  by  reference  in this
Prospectus  untrue in any material  respect or which causes this  Prospectus  to
omit to  state a  material  fact  necessary  in  order  to make  the  statements
contained or incorporated  by reference  herein,  in light of the  circumstances
under which they were made, not misleading or of the occurrence of certain other
events  specified  in the  Registration  Rights  Agreement,  such  Participating
Broker-Dealer  will  suspend  the  sale of New  Capital  Securities  (or the New
Guarantee or the New Junior Subordinated Debentures,  as applicable) pursuant to
this Prospectus until the Company or the Trust has amended or supplemented  this
Prospectus to correct such  misstatement or omission and has furnished copies of
the amended or supplemented  Prospectus to such  Participating  Broker-Dealer or
the  Company  or the  Trust has given  notice  that the sale of the New  Capital
Securities (or the New Guarantee or the New Junior Subordinated  Debentures,  as
applicable)  may be  resumed,  as the case may be. If the  Company  or the Trust
gives such notice to suspend the sale of the New Capital  Securities (or the New
Guarantee or the New Junior Subordinated  Debentures,  as applicable),  it shall
extend  the  90-  day  period  referred  to  above  during  which  Participating
Broker-Dealers are entitled to use this Prospectus in connection with the resale
of New  Capital  Securities  by the number of days  during  the period  from and
including  the date of the giving of such notice to and  including the date when
Participating  Broker-Dealers  shall  have  received  copies of the  amended  or
supplemented   Prospectus  necessary  to  permit  resales  of  the  New  Capital
Securities  or to and  including  the date on which the Company or the Trust has
given notice that the sale of New Capital  Securities  (or the New  Guarantee or
the New Junior  Subordinated  Debentures,  as applicable) may be resumed, as the
case may be.

         Prior to the Exchange  Offer,  there has been only a limited  secondary
market and no public  market for the Old  Capital  Securities.  The New  Capital
Securities  will be a new issue of  securities  for which there  currently is no
market.  Although the Initial Purchasers have informed the Company and the Trust
that they each currently intend to make a market in the New Capital  Securities,
they are not obligated to do so, and any such market making may be  discontinued
at any time  without  notice.  Accordingly,  there can be no assurance as to the
development  or  liquidity  of any market for the New  Capital  Securities.  The
Company  and the Trust  currently  do not intend to apply for listing of the New
Capital  Securities  on any  securities  exchange or for  quotation  through the
National Association of Securities Dealers Automated Quotation System.

         Any Old Capital  Securities  not  tendered and accepted in the Exchange
Offer will  remain  outstanding  and will be entitled to all the same rights and
will be  subject  to the same  limitations  applicable  thereto  under the Trust
Agreement  (except for those rights which  terminate  upon  consummation  of the
Exchange  Offer).  Following  consummation of the Exchange Offer, the holders of
Old  Capital  Securities  will  continue  to be subject  to all of the  existing
restrictions  upon  transfer  thereof and neither the Company nor the Trust will
have any further  obligation to such holders  (other than under certain  limited
circumstances)  to provide for registration  under the Securities Act of the Old
Capital  Securities held by them. To the extent that Old Capital  Securities are
tendered  and  accepted  in the  Exchange  Offer,  a  holder's  ability  to sell
untendered  Old  Capital  Securities  could be  adversely  affected.  See  "Risk
Factors--Consequences of a Failure to Exchange Old Capital Securities."

         THIS PROSPECTUS AND THE RELATED LETTER OF TRANSMITTAL CONTAIN IMPORTANT
INFORMATION. HOLDERS OF OLD CAPITAL SECURITIES ARE URGED TO READ THIS PROSPECTUS
AND THE RELATED  LETTER OF  TRANSMITTAL  CAREFULLY  BEFORE  DECIDING  WHETHER TO
TENDER THEIR OLD CAPITAL SECURITIES PURSUANT TO THE EXCHANGE OFFER.

         Old Capital Securities may be tendered for exchange on or prior to 5:00
p.m.,  New York City time,  on , 1997 (such time on such date being  hereinafter
called the  "Expiration  Date"),  unless the  Exchange  Offer is extended by the
Company or the Trust (in which case the term  "Expiration  Date"  shall mean the
latest date and time to which the Exchange  Offer is  extended).  Tenders of Old
Capital  Securities  may be withdrawn at any time on or prior to the  Expiration
Date. The Exchange Offer is not conditioned upon any minimum  Liquidation Amount
of Old Capital  Securities  being tendered for exchange.  However,  the Exchange
Offer is  subject to certain  events and  conditions  which may be waived by the
Company or the Trust and to the terms and provisions of the Registration  Rights
Agreement.  Old Capital Securities may be tendered in whole or in part having an
aggregate  Liquidation Amount of not less than $100,000 (100 Capital Securities)
or any integral multiple of $1,000  Liquidation Amount (one Capital Security) in
excess  thereof.  The  Company has agreed to pay all  expenses  of the  Exchange
Offer. See "The Exchange Offer--Fees and Expenses." Holders of the Old Capital
Securities whose Old Capital Securities are accepted for exchange will not
receive  Distributions on such Old Capital  Securities and will be deemed to
have waived the right to receive any Distributions on such Old Capital
Securities  accumulated  from and  after  January  13,  1997.  See "The Exchange
Offer--Distributions on New Capital Securities."

         Neither the Company nor the Trust will receive any cash proceeds from
the issuance of the New Capital Securities offered hereby.  No dealer-manager is
being used in connection with this Exchange Offer.  See "Use of Proceeds" and
"Plan of Distribution."

No separate  financial  statements of the Trust have been included  herein.  The

under the Exchange Act, (ii) the Trust has no independent  operations and exists
for the sole purpose of issuing  securities  representing  undivided  beneficial
interests  in the  assets of the Trust and  investing  the  proceeds  thereof in
Junior  Subordinated  Debentures issued by the Company,  and (iii) the Company's
obligations  described herein to provide certain  indemnities in respect of, and
be responsible for, certain costs, expenses,  debts and liabilities of the Trust
under the Indenture and any supplemental  indenture  thereto and pursuant to the
Declaration  of  the  Trust,  the  guarantee  issued  with  respect  to  Capital
Securities issued by the Trust, the Junior Subordinated  Debentures purchased by
Markel Capital Trust I and the related Indenture,  taken together,  constitute a
full and unconditional guarantee of payments due on the Capital Securities.  See
"Description  of New Junior  Subordinated  Debentures"  and  "Description of the
Guarantee."

The Trust is not currently subject to the information reporting  requirements of
the Exchange Act. The Trust will become  subject to such  requirements  upon the
effectiveness  of the  Registration  Statement,  although it intends to seek and
expects to receive exemptions therefrom.

                                    SUMMARY

The  following  summary  is  qualified  in its  entirety  by the  more  detailed
information  appearing  elsewhere  in or  incorporated  by  reference  into this
Prospectus.

                             Markel Capital Trust I

The Trust is a statutory business trust created under Delaware law by the filing
of a certificate  of trust with the Delaware  Secretary of State on December 30,
1996. The Trust is governed by an Amended and Restated Declaration of Trust (the
"Declaration") executed by the Company, as Sponsor, The Chase Manhattan Bank, as
Property Trustee, and The Chase Manhattan Bank Delaware, as Delaware Trustee and
the three individual Administrative Trustees named therein. The Trust's business
and affairs are  conducted by the Issuer  Trustees:  the Property  Trustee,  the
Delaware  Trustee,  and the three  individual  Administrative  Trustees  who are
employees or officers of or  affiliated  with the Company.  The Trust exists for
the  exclusive  purposes of (i) issuing and selling the Trust  Securities,  (ii)
using the proceeds  from the sale of the Trust  Securities to acquire the Junior
Subordinated  Debentures  issued by the Company and (iii) engaging in only those
other activities necessary, advisable or incidental thereto (such as registering
the  transfer of the Trust  Securities).  Accordingly,  the Junior  Subordinated
Debentures  will be the sole assets of the Trust,  and payments under the Junior
Subordinated Debentures will be the sole revenue of the Trust. All of the Common
Securities are owned by the Company.

                               Markel Corporation

Markel   Corporation  is  an  insurance  holding  company  which,   through  its
subsidiaries,  markets and underwrites specialty insurance products and programs
to a variety of niche markets.  The Company believes that its specialty  product
focus and niche market  strategy enable it to develop  particular  expertise and
specialized  knowledge of its markets. Such specialization allows the Company to
provide added value to its customers and to compete on a basis other than price.
The year ended December 31, 1995 marked the Company's fourth consecutive year of
underwriting  profitability and the ninth year of underwriting  profitability in
the last ten years. The Company  emphasizes quality service in all phases of its
operations and believes that this approach fosters strong relationships with its
producers and greater customer loyalty.

The Company's primary businesses are professional and products liability, excess
and surplus lines,  specialty programs,  specialty personal and commercial lines
and brokered  excess and surplus  lines.  The  Company's  distribution  channels
include  retail  and  wholesale  brokers,   general  agents,  direct  marketing,
including telemarketing and direct mail, and affinity groups. The Company offers
products  and  coverages  designed  to meet the  needs of  insureds  in niche or
emerging  markets or insureds with  specialized  exposures or risks that are not
adequately  served  by  the  standard  markets.   Significant  products  include
professional liability coverages for doctors, lawyers, architects, engineers and
other  professionals,  comprehensive  programs  for summer camps and other youth
recreation  organizations,  conference  centers,  child  care  centers,  private
schools,  martial arts  schools,  gymnastics  schools,  dance  studios and horse
farms,  and property and liability  coverages for restaurants  and bars,  vacant
properties  and  hard-to-  place  property  risks,  yachts,  jet skis and  other
watercraft, mobile homes and other non-standard dwellings, taxi fleets and other
commercial  vehicles.  Each risk is generally considered on an individual basis,
and coverages  typically include limit  restrictions,  deductibles,  exclusions,
surcharges and other features which respond to distinctive risk characteristics.

The Company had earned  premiums  of $285.1  million and $225.1  million for the
year ended  December 31, 1995 and for the nine months ended  September 30, 1996,
respectively.  As of  September  30,  1996,  the  Company  had  total  assets of
approximately $1.4 billion and shareholders' equity of $247.8 million.

Resales of New Capital Securities....  The  Company  and the Trust are making
                                       the  Exchange  Offer in  reliance  on the
                                       position of the staff of the Division of
                                       Corporation  Finance of the Commission as
                                       set forth in certain interpretive letters
                                       addressed to third parties in other
                                       transactions.  However,  neither  the
                                       Company  nor the Trust has sought its own
                                       interpretive letter and there can be no
                                       assurance that the staff of the Division
                                       of Corporation Finance of the Commission
                                       would make a similar determination with
                                       respect to the Exchange  Offer as it has
                                       in such  interpretive  letters to third
                                       parties.  Based  on  these
                                       interpretations  by the  staff  of the
                                       Division  of Corporation  Finance  of the
                                       Commission,  and  subject  to the two
                                       immediately following  sentences,  the
                                       Company  and the  Trust  believe  that
                                       New  Capital Securities  issued  pursuant
                                       to this Exchange  Offer in exchange for
                                       Old Capital Securities  may be offered
                                       for resale,  resold and  otherwise

                                       than a holder who is a  broker-dealer)
                                       without  further compliance with the
                                       registration  and prospectus  delivery
                                       requirements of the Securities  Act,
                                       provided that such New Capital
                                       Securities are acquired in the ordinary
                                       course  of  such  holder's  business  and
                                       that  such  holder  is  not
                                       participating,  and has no  arrangement
                                       or  understanding  with any  person  to

                                       such New Capital Securities.  However,
                                       any holder of Old Capital Securities who
                                       is an  "affiliate"  of the Company or the
                                       Trust or who intends to participate in
                                       the Exchange Offer for the purpose of
                                       distributing  the New Capital
                                       Securities, or any broker-dealer who
                                       purchased the Old Capital  Securities
                                       from the Trust to resell  pursuant  to
                                       Rule  144A  or any  other  available
                                       exemption  under  the Securities Act, (a)
                                       will not be able to rely on the
                                       interpretations of the staff of the
                                       Division  of  Corporation  Finance  of
                                       the  Commission  set forth in the

                                       below, if any broker-dealer holds Old
                                       Capital Securities acquired  for its own

                                       that it acquired the Old Capital
                                       Securities for its own account as the

                                       mandatory redemption in a Like Amount,
                                       (i) in whole but not in part, on the
                                       Stated Maturity Date upon repayment of
                                       the Junior Subordinated Debentures, (ii)
                                       in whole but not in part, at any time
                                       contemporaneously with the optional
                                       prepayment of the Junior Subordinated
                                       Debentures by the Company upon the
                                       occurrence and continuation of a Special
                                       Event and (iii) in whole or in part, on
                                       or after January 1, 2007

                                       prepayment by the Company of the Junior
                                       Subordinated Debentures, in each case at
                                       the applicable Redemption Price. See
                                       "Description of New Securities --

Absence of Market for the Capital
Securities...........................  The New Capital  Securities  will be a
                                       new issue of  securities  for which there
                                       currently  is no  market.  Although
                                       Donaldson,  Lufkin  &  Jenrette
                                       Securities Corporation  and Smith Barney,
                                       Inc. the initial  purchasers of the Old
                                       Capital Securities  (the "Initial
                                       Purchasers")  have informed the Trust and
                                       the Company that they each currently
                                       intend to make a market in the Capital
                                       Securities,  the Initial Purchasers are
                                       not obligated to do so, and any such
                                       market making may be discontinued at any
                                       time without notice. Accordingly,  there
                                       can be no assurance as to the development
                                       or liquidity of any market for the New
                                       Capital Securities. The Trust and the
                                       Company do not intend to apply for
                                       listing of the New Capital Securities on

                                  RISK FACTORS

PROSPECTIVE  INVESTORS  SHOULD  CONSIDER  CAREFULLY,  IN  ADDITION  TO THE OTHER
INFORMATION  CONTAINED IN THIS PROSPECTUS,  THE FOLLOWING  FACTORS IN CONNECTION
WITH THE EXCHANGE OFFER AND THE NEW CAPITAL SECURITIES OFFERED HEREBY.

Holding Company Structure; Restrictions on Dividends

As a holding company, the Company's ability to meet debt service obligations and
pay operating  expenses  depends on receipt of sufficient  funds from its direct
and indirect  subsidiaries.  The inability of the Company's  direct and indirect
subsidiaries  to pay  dividends to the Company in an amount  sufficient  to meet
debt  service  obligations  and pay  operating  expenses  would  have a material
adverse  effect on the  Company.  The  payment  of  dividends  by the  Company's
subsidiaries  without prior  regulatory  approval is subject to restrictions set
forth in the insurance laws and regulations of Virginia, Illinois, Delaware, New
Jersey,  California  and  Arizona,  the  states  of  domicile  of the  Company's
insurance  subsidiaries.  The Company  currently does not expect such regulatory
requirements to impair its ability to meet interest  payment  obligations and to
pay operating expenses in the future. However, the Company can give no assurance
that dividends will be declared or paid by its subsidiaries.  As of December 31,
1995, the Company's  direct and indirect  insurance  subsidiaries had sufficient
capital and  earnings  to pay up to $36.2  million of  dividends  to the Company
during 1996 without prior regulatory approval.

Ranking of Subordinate Obligations Under the Guarantee and Junior Subordinated
Debentures

The obligations of the Company under the Guarantee  issued by it for the benefit
of the holders of Capital Securities and the Junior Subordinated  Debentures are
unsecured and subordinate and rank junior in right of payment to all present and
future Senior  Indebtedness of the Company and rank pari passu with  obligations
to or rights of the Company's other general unsecured creditors. In addition, in
the case of a bankruptcy or  insolvency  proceeding  involving the Company,  the
Company's  obligations  under the Guarantee will rank  subordinate and junior in
right of  payment  to all  liabilities  (other  than  Other  Guarantees)  of the
Company,  but senior to any  obligation in respect of any class of capital stock
of the Company.  No payment may be made of the principal of, or premium, if any,
or  interest  on  the  Junior  Subordinated  Debentures,  or in  respect  of any
redemption,  retirement,  purchase  or other  acquisition  of any of the  Junior
Subordinated Debentures,  at any time when (i) there is a default in the payment
of the principal of, or premium,  if any, or interest on or otherwise in respect
of  any  Senior  Indebtedness,  whether  at  maturity  or at a  date  fixed  for
prepayment or by  declaration  or  otherwise,  or (ii) any event of default with
respect to any Senior  Indebtedness  has  occurred and is  continuing,  or would
occur as a result of such payment on the Junior  Subordinated  Debentures or any
redemption,  retirement,  purchase  or other  acquisition  of any of the  Junior
Subordinated Debentures,  permitting the holders of such Senior Indebtedness (or
a trustee on behalf of the holders thereof) to accelerate the maturity  thereof.
At December 31, 1996,  the  aggregate  principal  amount of  outstanding  Senior
Indebtedness  of the  Company  was  approximately  $120.3  million.  Because the
Company is a holding  company,  the right of the Company to  participate  in any
distribution  of  assets  of  any  direct  or  indirect   subsidiary  upon  such
subsidiary's liquidation or reorganization or otherwise (and thus the ability of
holders of the Capital  Securities to benefit indirectly from such distribution)
is subject to the prior claims of creditors  of that  subsidiary,  except to the
extent  that  the  Company  may  itself  be  recognized  as a  creditor  of that
subsidiary.  At September 30, 1996, the direct and indirect  subsidiaries of the
Company had total  liabilities  (excluding  liabilities  owed to the Company) of
approximately  $1.0  billion.  In  addition,   because  many  of  the  Company's
subsidiaries are insurance  companies  subject to regulatory  control by various
state insurance  departments,  the ability of such subsidiaries to pay dividends
to the Company without prior  regulatory  approval is limited by applicable laws
and  regulations.  Accordingly,  the  Junior  Subordinated  Debentures  will  be
effectively subordinated to all existing and future liabilities of the Company's
subsidiaries,  and holders of Junior Subordinated Debentures should look only to
the assets of the Company for  payments on the Junior  Subordinated  Debentures.
None of the Indenture,  the Guarantee,  the Common  Guarantee or the Declaration
places any  limitation  on the amount of secured or  unsecured  debt,  including
Senior Indebtedness,  or other obligations,  that may be incurred by the Company
or  any  of  its  subsidiaries,  either  in  the  event  of a  highly  leveraged
transaction  or  otherwise.  See  "Description  of the  Guarantee -- Status" and
"Description of the New Junior Subordinated Debentures -- Subordination."


<PAGE>


The ability of the Trust to pay amounts due on the Capital  Securities is solely
dependent  upon  the  Company's  making  payments  on  the  Junior  Subordinated
Debentures as and when required.

Option to Extend Interest Payment Period; Tax Considerations

So long as no Debenture Event of Default (as defined herein) shall have occurred
and be continuing,  the Company will have the right under the Indenture to defer
payments of interest on the Junior  Subordinated  Debentures at any time or from
time to time for a period not exceeding 10 consecutive  semi-annual periods with
respect to each Extension  Period,  provided that no Extension Period may extend
beyond  the  Stated   Maturity  Date.   Upon  any  such  deferral,   semi-annual
Distributions  on the Capital  Securities by the Trust will be deferred (and the
amount of Distributions to which holders of the Capital  Securities are entitled
will accumulate additional Distributions thereon at the rate of 8.71% per annum,
compounded  semi-annually,  but not exceeding the interest rate then accruing on
the Junior  Subordinated  Debentures)  from the  relevant  payment date for such
Distributions during any such Extension Period.

The  Company  may extend  any  existing  Extension  Period,  provided  that such
extension  does not  cause  such  Extension  Period  to  exceed  10  consecutive
semi-annual  periods  or to extend  beyond the Stated  Maturity  Date.  Upon the
termination of any Extension Period and the payment of all interest then accrued
and unpaid on the Junior Subordinated Debentures (together with interest thereon
at the annual rate of 8.71%, compounded  semi-annually,  to the extent permitted
by  applicable  law),  the  Company may elect to begin a new  Extension  Period,
subject to the above requirements. There is no limitation on the number of times
that the Company may elect to begin an Extension Period. See "Description of New
Securities  --  Distributions"  and  "Description  of  New  Junior  Subordinated
Debentures -- Option to Extend Interest Payment Date."

Should the  Company  exercise  its right to defer  payments  of  interest on the
Junior  Subordinated  Debentures,  each  holder of  Capital  Securities  will be
required to accrue income (as original issue discount ("OID")) in respect of the
deferred stated interest  allocable to its Capital  Securities for United States
federal  income tax  purposes,  which will be allocated but not  distributed  to
holders of Capital  Securities.  As a result,  during an Extension Period,  each
holder of Capital  Securities  will  recognize  income for United States federal
income tax  purposes  in advance of the receipt of cash and will not receive the
cash related to such income from the Trust if the holder disposes of the Capital
Securities prior to the record date for the payment of Distributions thereafter.
See "Certain  Federal Income Tax  Consequences  -- Interest  Income and Original
Issue Discount" and " -- Sales of Capital Securities."

Should the Company elect to exercise its right to defer  payments of interest on
the Junior Subordinated Debentures, the then current market price of the Capital
Securities  is likely to be affected  adversely.  A holder that  disposes of its
Capital Securities during an Extension Period, therefore,  might not receive the
same return on its  investment  as a holder that  continues  to hold its Capital
Securities.  In addition,  the mere  existence of the  Company's  right to defer
payments of interest on the Junior Subordinated  Debentures may cause the market
price of the Capital  Securities  to be more  volatile than the market prices of
other  securities  on which OID accrues  that are not  subject to such  deferral
rights.

Conditional Right to Advance Maturity and Special Event Redemption

If a Tax Event (as defined herein) occurs,  then the Company will have the right
(i) prior to the  termination of the Trust,  to advance the Stated Maturity Date
of the Junior Subordinated Debentures to the minimum extent required in order to
allow for the  payments  of  interest  in  respect  of the  Junior  Subordinated
Debentures to continue to be tax deductible, but in no event shall the resulting
maturity  of the  Junior  Subordinated  Debentures  be less  than 20 years  from
January 13, 1997, or (ii) to terminate the Trust (if not previously  terminated)
and advance the Stated  Maturity Date of the Junior  Subordinated  Debentures to
the minimum  extent  required in order to allow for the  payments of interest in
respect of the Junior  Subordinated  Debentures to continue to be tax deductible
for  United  States  federal  income  tax  purposes,  but in no event  shall the
resulting maturity of the Junior  Subordinated  Debentures be less than 40 years
from January 13, 1997. In either case, such maturity date shall be advanced only
if, in the opinion of counsel to the Company experienced in such matters,  after
advancing the maturity date, interest paid on the Junior Subordinated Debentures
will be  deductible  for United States  federal  income tax purposes (the action
referred  to in either  clause (i) or (ii) above  being  referred to herein as a
"Tax Event Maturity Advancement").

If a Tax Event  occurs and in the opinion of counsel to the Company  experienced
in such matters,  there would in all cases, after effecting a Tax Event Maturity
Advancement,  be more than an insubstantial risk that an Adverse Tax Consequence
(as defined herein) would continue to exist, or, if an Investment  Company Event
(as defined herein) occurs, then the Company will have the right, within 90 days
following the occurrence of such Tax Event or Investment  Company Event,  as the
case may be, to redeem the Junior  Subordinated  Debentures in whole (but not in
part) in the  manner set forth  under  "Description  of New Junior  Subordinated
Debentures  --  Conditional   Right  to  Advance   Maturity  and  Special  Event
Prepayment,"  and  therefore  to cause a  mandatory  redemption  of the  Capital
Securities prior to the Stated Maturity Date (the circumstances  under which the
Company  has the  right to so  redeem  the  Junior  Subordinated  Debentures  in
connection  with a Tax Event  being  referred  to herein as a  "Conditional  Tax
Redemption Event").  Each of a Conditional Tax Redemption Event or an Investment
Company Event are sometimes referred to herein as a "Special Event".

<PAGE>

Possible Distribution of Junior Subordinated Debentures

The  Company  will have the right at any time to dissolve  the Trust and,  after
satisfaction  of claims of creditors of the Trust as provided by applicable law,
to cause the Junior Subordinated  Debentures to be distributed to the holders of
the Trust  Securities.  Under current  United States  federal  income tax law, a
distribution of Junior Subordinated Debentures upon the dissolution of the Trust
would not be a taxable event to holders of the Capital Securities.  If, however,
the Trust is  characterized  for United States federal income tax purposes as an
association  taxable as a corporation  at the time of  dissolution of the Trust,
the distribution of the Junior Subordinated  Debentures may constitute a taxable
event to holders of  Capital  Securities.  Moreover,  upon the  occurrence  of a
Special  Event,  a  dissolution  of the Trust in which  holders  of the  Capital
Securities  receive cash would be a taxable event to such holders.  See "Certain
Federal Income Tax Consequences -- Receipt of Junior Subordinated  Debentures or
Cash Upon Liquidation of the Trust."

Possible Tax Law Changes Affecting the Capital Securities

On February 6, 1997, as part of the Clinton  Administration's Fiscal 1998 Budget
Proposal,   the  Treasury   Department   proposed   legislation  (the  "Proposed
Legislation") which would, among other things,  generally deny corporate issuers
a deduction for interest in respect of certain debt obligations, such as the New
Junior Subordinated Debentures,  issued on or after the date "of first committee
action," if such debt  obligations  had a maximum term in excess of 15 years and
are not shown as indebtedness on the issuer's  applicable  consolidated  balance
sheet.  In addition,  the Proposed  Legislation  would  generally deny corporate
issuers a deduction for interest in respect of certain debt obligations, such as
the New Junior  Subordinated  Debentures,  issued on or after the date "of first
committee action,", if such debt obligations have a weighted average maturity of
more than 40 years. The Proposed  Legislation has not yet been introduced by any
member of the 105th  Congress.  If other  Proposed  Legislation  is  enacted  by
Congress and if such  enactment  gave rise to a Tax Event,  the Company would be
permitted to cause a redemption  of the Trust  Securities  at the Special  Event
Redemption Price by electing to prepay the Junior Subordinated Debentures at the
Special  Event   Prepayment   Price.  See  "Description  of  New  Securities  --
Conditional  Right to  Advance  Maturity  and  Special  Event  Redemption,"  "--
Description  of New  Junior  Subordinated  Debentures  --  Conditional  Right to
Advance  Maturity and Special Event  Prepayment"  and Certain Federal Income Tax
Consequences -- Proposed Tax Legislation.

Possible Adverse Effect on Market Prices

There can be no  assurance  as to the market  prices for Capital  Securities  or
Junior Subordinated  Debentures distributed to the holders of Capital Securities
if a termination of the Trust were to occur. Accordingly, the Capital Securities
or the Junior  Subordinated  Debentures  may trade at a discount  from the price
that the  investor  paid to purchase  the  Capital  Securities  offered  hereby.
Because holders of Capital Securities may receive Junior Subordinated Debentures
in liquidation of the Trust and because  Distributions  are otherwise limited to
payments  on the  Junior  Subordinated  Debentures,  prospective  purchasers  of
Capital  Securities  are also making an  investment  decision with regard to the
Junior  Subordinated  Debentures and should carefully review all the information
regarding the Junior Subordinated  Debentures contained herein. See "Description
of New Junior Subordinated Debentures."

Rights Under the Guarantee

The  Chase  Manhattan  Bank  will act as  Guarantee  Trustee  and will  hold the
Guarantee  for the benefit of the holders of the Capital  Securities.  The Chase
Manhattan Bank will also act as Property Trustee and as Debenture  Trustee under
the Indenture.  Chase  Manhattan Bank Delaware will act as Delaware  Trustee
under the Declaration.  The Old Guarantee guarantees, and the New Guarantee will
guarantee,  as the case may be, to the  holders of the  Capital  Securities  the
following payments, to the extent not paid by the Trust: (i) any accumulated and
unpaid  Distributions  required  to be paid on the  Capital  Securities,  to the
extent that the Trust has funds on hand  legally  available  therefor;  (ii) the
applicable  Redemption Price with respect to any Capital  Securities  called for
redemption,  to the extent that the Trust has funds on hand at that time legally
available  therefor;  and (iii) upon a voluntary or involuntary  termination and
liquidation  of  the  Trust  (unless  the  Junior  Subordinated  Debentures  are
distributed  to  holders  of the  Capital  Securities),  the  lesser  of (a) the
aggregate of the Liquidation Amount and all accumulated and unpaid Distributions
to the date of  payment,  to the extent that the Trust has funds on hand at that
time  legally  available  therefor  and (b) the  amount  of  assets of the Trust
remaining available for distribution to holders of the Capital  Securities.  The
obligations  of the Company under the Guarantee are  subordinated  in the manner
set forth under " -- Ranking of Subordinate  Obligations Under the Guarantee and
Junior Subordinated Debentures." The holders of a majority in Liquidation Amount
of the  Capital  Securities  will have the right to direct the time,  method and
place of conducting  any  proceeding  for any remedy  available to the Guarantee
Trustee in respect of the Guarantee or to direct the exercise of any trust power
conferred upon the Guarantee  Trustee.  Any holder of the Capital Securities may
institute a legal proceeding  directly against the Company to enforce its rights
under the Guarantee  without first  instituting a legal  proceeding  against the
Trust,  the  Guarantee  Trustee or any other  person or entity.  If the  Company
defaults on its obligation to pay amounts payable under the Junior  Subordinated
Debentures,  the  Trust  will not  have  sufficient  funds  for the  payment  of
Distributions  or amounts  payable on  redemption  of the Capital  Securities or
otherwise,  and, in such event,  holders of the Capital  Securities  will not be
able to rely upon the Guarantee for payment of such  amounts.  Instead,  in the
event a  Debenture  Event of Default shall have  occurred and be  continuing and
such event is  attributable  to the failure of the Company to pay  principal  of
or premium,  if any, or interest on the Junior Subordinated  Debentures on the
payment date on which such payment is due and  payable,  then a holder of
Capital  Securities  may  institute  a legal proceeding  directly  against  the
Company  for  enforcement  of payment to such holder of the  principal  of or
premium,  if any,  or  interest  on such Junior Subordinated  Debentures  having
a  principal  amount  equal to the  Liquidation Amount  of  the  Capital
Securities  of  such  holder  (a  "Direct   Action"). Notwithstanding  any
payments  made to a holder of  Capital  Securities  by the Company in connection
with a Direct Action,  the Company shall remain  obligated to pay  the principal

<PAGE>

of and  premium,  if any,  and  interest  on the  Junior Subordinated
Debentures,  and the Company  shall be subrogated to the rights of the holder of
such  Capital  Securities  with respect to payments on the Capital Securities to
the extent of any payments  made by the Company to such holder in any Direct
Action.  Except as described  herein,  holders of Capital  Securities will not
be able to exercise  directly any other remedy available to the holders of the
Junior Subordinated  Debentures or to assert directly any other rights in
respect of the Junior  Subordinated  Debentures.  See "Description of New Junior
Subordinated  Debentures --  Enforcement of Certain Rights by Holders of Capital
Securities"  and " --  Debenture  Events of  Default"  and  "Description  of the
Guarantee." The Declaration will provide that each holder of Capital  Securities
by acceptance thereof agrees to the provisions of the Indenture.

Limited Voting Rights

Holders of Capital Securities will generally have limited voting rights relating
only  to  the  modification  of  the  terms  of  the  Capital  Securities,   the
dissolution,  termination or  liquidation of the Trust,  and the exercise of the
Trust's  rights as holder of the  Junior  Subordinated  Debentures.  Holders  of
Capital  Securities will not be entitled to vote to appoint,  remove or replace,
or to increase  or decrease  the number of, the Issuer  Trustees,  which  voting
rights are vested exclusively in the holder of the Common Securities,  except as
described under  "Description of New Securities -- Removal of Issuer  Trustees."
The Issuer  Trustees  and the  Company  may amend the  Declaration  without  the
consent  of  holders  of  Capital  Securities  to ensure  that the Trust will be
classified for United States federal income tax purposes as a grantor trust even
if such action adversely affects the interests of such holders. See "Description
of New Securities -- Voting Rights; Amendment of the Declaration."

Trading Price

The  Capital  Securities  may trade at a price that does not fully  reflect  the
value of accrued  but unpaid  interest  with  respect to the  underlying  Junior
Subordinated  Debentures.  A holder which uses the accrual  method of accounting
for  tax  purposes  (and a  cash  method  holder,  if  the  Junior  Subordinated
Debentures  are deemed to have been issued  with OID) and which  disposes of its
Capital  Securities  between record dates for payments of distributions  thereon
will  be  required  to  include  accrued  but  unpaid  interest  on  the  Junior
Subordinated  Debentures  through the date of  disposition in income as ordinary
income  (i.e.,  interest  or,  possibly,  OID),  and to add such  amount  to its
adjusted tax basis in its share of the underlying Junior Subordinated Debentures
deemed  disposed  of. To the extent the selling  price is less than the holder's
adjusted  tax basis  (which will  include all  accrued but unpaid  interest),  a
holder will  recognize a capital loss.  Subject to certain  limited  exceptions,
capital  losses  cannot be applied to offset  ordinary  income for United States
federal income tax purposes.  See "Certain  Federal Income Tax  Consequences  --
Interest  Income  and  Original  Issue  Discount"  and  " --  Sales  of  Capital
Securities."

Consequences of a Failure to Exchange Old Capital Securities

The Old Capital  Securities have not been registered under the Securities Act or
any state  securities  laws and therefore may not be offered,  sold or otherwise
transferred  except in  compliance  with the  registration  requirements  of the
Securities  Act and any other  applicable  securities  laws,  or  pursuant to an
exemption therefrom or in a transaction not subject thereto, and in each case in
compliance  with  certain  other  conditions  and   restrictions.   Old  Capital
Securities  which remain  outstanding  after  consummation of the Exchange Offer
will continue to bear a legend  reflecting  such  restrictions  on transfer.  In
addition,  upon  consummation  of the  Exchange  Offer,  holders of Old  Capital
Securities  which remain  outstanding will not be entitled to any rights to have
such Old  Capital  Securities  registered  under  the  Securities  Act or to any
similar  rights  under the  Registration  Rights  Agreement  (subject to certain
limited  exceptions).  The Company and the Trust do not intend to register under
the Securities Act any Old Capital  Securities  which remain  outstanding  after
consummation  of the  Exchange  Offer  (subject to such limited  exceptions,  if
applicable). To the extent that Old Capital Securities are tendered and accepted
in the  Exchange  Offer,  a holder's  ability  to sell  untendered  Old  Capital
Securities could be adversely affected.

The  New  Capital  Securities  and  any  Old  Capital  Securities  which  remain
outstanding  after  consummation  of the Exchange  Offer will vote together as a
single  class for  purposes  of  determining  whether  holders of the  requisite
percentage in outstanding  Liquidation Amount thereof have taken certain actions
or exercised  certain rights under the Trust Agreement.  See "Description of New
Securities--Voting Rights; Amendment of the Declaration."

The Old Capital Securities provide,  among other things, that, if a registration
statement  relating to the Exchange Offer has not been filed by June 7, 1997 and
declared  effective  by July 7,  1997,  the  Distribution  rate borne by the Old
Capital  Securities  commencing on July 8, 1997 will increase by 0.25% per annum
until the Exchange Offer is consummated.  Upon consummation of the Exchange
Offer, holders of Old Capital Securities will not be entitled to any increase in
the Distribution rate thereon or any further registration rights under the
Registration Rights Agreement, except under limited circumstances.  See
"Description of Old Securities."

Absence of Public Market

The Old  Capital  Securities  were  issued to,  and the  Company  believes  such
securities  are  currently  owned by, a relatively  small  number of  beneficial
owners. The Old Capital Securities have not been registered under the Securities
Act and will be  subject  to  restrictions  on  transferability  if they are not
exchanged for the New Capital  Securities.  Although the New Capital  Securities
may be resold or otherwise transferred by the holders (who are not affiliates of
the Company or the Trust) without compliance with the registration  requirements
under the Securities Act, they will constitute a new issue of securities with no
established  trading  market.  Old Capital  Securities may be transferred by the
holders  thereof  only in blocks  having a  Liquidation  Amount of not less than
$100,000 (100 Old Capital Securities). New Capital Securities may be transferred
by the holders thereof in blocks having a Liquidation  Amount of $1,000 (one New
Capital Security) or integral multiples thereof.  The Company and the Trust have
been advised by the Initial  Purchasers  that the Initial  Purchasers  presently
intend to make a market in the New  Capital  Securities.  However,  the  Initial
Purchasers  are not  obligated  to do so and  any  market-making  activity  with
respect to the New Capital  Securities may be  discontinued  at any time without
notice. In addition,  such market-making  activity will be subject to the limits
imposed by the Securities Act and the Exchange Act and may be limited during the
Exchange Offer. Accordingly,  no assurance can be given that an active public or
other  market will  develop for the New  Capital  Securities  or the Old Capital
Securities or as to the  liquidity of or the trading  market for the New Capital
Securities  or the Old Capital  Securities.  If an active public market does not
develop,  the market price and  liquidity of the New Capital  Securities  may be
adversely affected.

If a public  trading  market  develops  for the New Capital  Securities,  future
trading  prices  will depend on many  factors,  including,  among other  things,
prevailing  interest  rates,  the  Company's  results and the market for similar
securities.  Depending  on  prevailing  interest  rates,  the market for similar
securities and other factors,  including the financial condition of the Company,
the New Capital Securities may trade at a discount.

Notwithstanding  the registration of the New Capital  Securities in the Exchange
Offer, holders who are "affiliates" (as defined under Rule 405 of the Securities
Act) of the Company or the Trust may  publicly  offer for sale or resell the New
Capital  Securities only in compliance with the provisions of Rule 144 under the
Securities Act.

Each  broker-dealer  that receives New Capital Securities for its own account in
exchange  for Old Capital  Securities,  where such Old Capital  Securities  were
acquired by such broker-dealer as a result of market-making  activities or other
trading  activities,  must  acknowledge  that it will  deliver a  prospectus  in
connection  with  any  resale  of such  New  Capital  Securities.  See  "Plan of
Distribution."

Exchange Offer Procedures

Issuance of the New Capital  Securities  in exchange for Old Capital  Securities
pursuant to the Exchange  Offer will be made only after a timely  receipt by the
Trust of such Old Capital  Securities,  a properly  completed  and duly executed
Letter of Transmittal and all other required  documents.  Therefore,  holders of
the Old Capital  Securities  desiring to tender such Old Capital  Securities  in
exchange  for New Capital  Securities  should  allow  sufficient  time to ensure
timely  delivery.  Neither  the  Company nor the Trust is under any duty to give
notification  of defects or  irregularities  with  respect to the tenders of Old
Capital Securities for exchange.

                               MARKEL CORPORATION

Markel   Corporation  is  an  insurance  holding  company  which,   through  its
subsidiaries,  markets and underwrites specialty insurance products and programs
to a variety of niche markets.  The Company believes that its specialty  product
focus and niche market  strategy enable it to develop  particular  expertise and
specialized  knowledge of its markets. Such specialization allows the Company to
provide added value to its customers and to compete on a basis other than price.
The year ended December 31, 1995 marked the Company's fourth consecutive year of
underwriting  profitability and the ninth year of underwriting  profitability in
the last ten years. The Company  emphasizes quality service in all phases of its
operations and believes that this approach fosters strong relationships with its
producers and greater customer loyalty.

The Company's primary businesses are professional and products liability, excess
and surplus lines,  specialty programs,  specialty personal and commercial lines
and brokered  excess and surplus  lines.  The  Company's  distribution  channels
include  retail  and  wholesale  brokers,   general  agents,  direct  marketing,
including telemarketing and direct mail, and affinity groups. The Company offers
products  and  coverages  designed  to meet the  needs of  insureds  in niche or
emerging  markets or insureds with  specialized  exposures or risks that are not
adequately  served  by  the  standard  markets.   Significant  products  include
professional liability coverages for doctors, lawyers, architects, engineers and
other  professionals,  comprehensive  programs  for summer camps and other youth
recreation  organizations,  conference  centers,  child  care  centers,  private
schools,  martial arts  schools,  gymnastics  schools,  dance  studios and horse
farms,  and property and liability  coverages for restaurants  and bars,  vacant
properties  and  hard-to-  place  property  risks,  yachts,  jet skis and  other
watercraft, mobile homes and other non-standard dwellings, taxi fleets and other
commercial  vehicles.  Each risk is generally considered on an individual basis,
and coverages  typically include limit  restrictions,  deductibles,  exclusions,
surcharges and other features which respond to distinctive risk characteristics.

The Company had earned  premiums  of $285.1  million and $225.1  million for the
year ended  December 31, 1995 and for the nine months ended  September 30, 1996,
respectively.  As of  September  30,  1996,  the  Company  had  total  assets of
approximately $1.4 billion and shareholders' equity of $247.8 million.

                                USE OF PROCEEDS

Neither  the  Company  nor the Trust will  receive  any cash  proceeds  from the
issuance of the New Capital  Securities  offered hereby.  In  consideration  for
issuing the New Capital  Securities  in exchange for Old Capital  Securities  as
described in this Prospectus,  the Trust will receive Old Capital  Securities in
like Liquidation Amount. The Old Capital Securities  surrendered in exchange for
the New Capital Securities will be retired and canceled.

The proceeds to the Trust from the sale of the Old Capital  Securities  (without
giving effect to expenses payable by the Company) was  $150,000,000.  All of the
proceeds were used to purchase Junior Subordinated  Debentures from the Company.
The  Company  intends  to use the  net  proceeds  from  the  sale of the  Junior
Subordinated  Debentures  to  reduce  indebtedness  and  for  general  corporate
purposes, which may include, without limitation,  investments in and advances of
credit to the Company's  subsidiaries,  other  investments  and possible  future
acquisitions.

                       RATIO OF EARNINGS TO FIXED CHARGES

The  following  table sets forth the  historical  ratios of earnings to combined
fixed charges of the Company for the periods indicated:

Brokerage Programs.............................................  1.6    2.2     3.1    3.8   5.2        5.7
</TABLE>

For  purposes  of  computing  the ratios of  earnings  to fixed  charges for the
Company and its subsidiaries, earnings represent income before income taxes plus
fixed  charges.  Fixed  charges have been  calculated  by adding gross  interest
expense and that portion of rent expense deemed  representative  of the interest
factor  in such rent  expense.  The  Company's  consolidated  insurance  company
subsidiaries  are subject to certain  regulatory  restrictions on the payment of
dividends  or  advances to the  Company.  See "Risk  Factors -- Holding  Company
Structure; Restrictions on Dividends".

                                 CAPITALIZATION

The following table sets forth the consolidated capitalization of the Company at
September  30,  1996,  as  adjusted  to reflect  the  acquisition  of  Investors
Insurance  Holding Corp. and related bank borrowings on October 31, 1996, and as
further  adjusted to give effect to the issuance of the Old Capital  Securities.
The following data should be read in conjunction with the financial  information
included in the Company's Annual Report on Form 10-K for the year ended December
31, 1995, as amended,  and  Quarterly  Report on Form 10-Q for the quarter ended

Securities in the Exchange  Offer will have no effect on the  Capitalization  of
the Company.

The Trust is a statutory business trust created under Delaware law by the filing
of a certificate  of trust with the Delaware  Secretary of State on December 30,
1996.  The  Trust is  governed  by the  Declaration.  The Trust  exists  for the
exclusive  purposes  of (i) issuing  and  selling  the Trust  Securities,  which
represent  undivided  beneficial  interests  in the  assets of the  Trust,  (ii)
investing the gross proceeds of the Trust Securities in the Junior  Subordinated
Debentures  and  (iii)  engaging  in  only  those  other  activities  necessary,
advisable or incidental thereto. Accordingly, the Junior Subordinated Debentures
will be the sole assets of the Trust and payments under the Junior  Subordinated
Debentures will be the sole revenues of the Trust. All of the Common  Securities
are owned by the  Company.  The  Common  Securities  will rank pari  passu,  and
payments will be made thereon pro rata, with the Capital Securities, except that
upon the occurrence and during the  continuance of an Event of Default under the
Declaration  resulting  from a  Debenture  Event of  Default,  the rights of the
Company  as  holder  of  the  Common   Securities  to  payments  in  respect  of
Distributions  and payments upon  liquidation,  redemption or otherwise  will be
subordinated  and rank  junior  to the  rights  of the  holders  of the  Capital
Securities.  See  "Description  of New  Securities  --  Subordination  of Common
Securities." The Company has acquired Common Securities in a Liquidation  Amount
equal to 3% of the total capital of the Trust. The Trust has a term of 50 years,
but may terminate  earlier as provided in the Declaration.  The Trust's business
and affairs are conducted by trustees (the "Issuer  Trustees")  appointed by the
Company as the holder of the Common Securities.  The Issuer Trustees will be The
Chase Manhattan Bank as the Property Trustee (the "Property Trustee"), The Chase
Manhattan Bank Delaware as the Delaware  Trustee (the "Delaware  Trustee"),  and
three individual trustees (the "Administrative  Trustees").  The Chase Manhattan
Bank,  as  Property  Trustee,  will  act as sole  indenture  trustee  under  the
Declaration.  The Chase Manhattan Bank will also act as indenture  trustee under
the  Guarantee  and  the  Indenture.  See  "Description  of the  Guarantee"  and
"Description of New Junior  Subordinated  Debentures."  The holder of the Common
Securities  of the Trust or, if an Event of Default  under the  Declaration  has
occurred and is continuing,  the holders of a majority in Liquidation  Amount of
the Capital  Securities,  will be  entitled  to  appoint,  remove or replace the
Property  Trustee and/or the Delaware  Trustee.  In no event will the holders of
the Capital Securities have the right to vote to appoint,  remove or replace the
Administrative  Trustees;  such voting rights will be vested  exclusively in the
holder of the  Common  Securities.  The duties and  obligations  of each  Issuer
Trustee are  governed by the  Declaration.  The  Company  will pay,  directly or
indirectly, all fees, expenses, debts and obligations (other than, except to the
extent guaranteed by the Company, the Trust Securities) related to the Trust and
the  offering  and  exchange of the Capital  Securities,  including  all ongoing
costs,  expenses and liabilities of the Trust. The principal executive office of
the Trust is c/o Markel Corporation,  4551 Cox Road, Glen Allen,  Virginia 23060
((804)  747-0136).  The Chase  Manhattan  Bank serves as the  trustee  under the
indenture for the Company's  $100 million  aggregate  principal  amount of 7.25%
Notes due  November  1,  2003,  and  participates  as a lender in the  Company's
revolving credit facility. In addition, from time to time one or more affiliates
of The Chase Manhattan Bank may provide the Company with investment  banking and
related financial services.


                               THE EXCHANGE OFFER

Purpose of the Exchange Offer

In connection with the sale of the Old Capital  Securities,  the Company and the
Trust  entered  into  the   Registration   Rights  Agreement  with  the  Initial
Purchasers,  pursuant to which the  Company and the Trust  agreed to file and to
use their reasonable  efforts to cause to become effective with the Commission a
registration  statement  with  respect  to  the  exchange  of  the  Old  Capital
Securities for capital  securities with terms identical in all material respects
to the terms of the Old Capital  Securities.  A copy of the Registration  Rights
Agreement  has been filed as an Exhibit to the  Registration  Statement of which
this Prospectus is a part.

The Exchange Offer is being made to satisfy the  contractual  obligations of the
Company  and the Trust under the  Registration  Rights  Agreement.  The form and
terms of the New  Capital  Securities  are the same as the form and terms of the
Old  Capital  Securities  except  that  the New  Capital  Securities  have  been
registered  under the  Securities  Act and will not be subject  to the  $100,000
minimum  Liquidation Amount transfer  restriction and certain other restrictions
on transfer  applicable to the Old Capital  Securities  and will not provide for
any increase in the Distribution rate thereon.  In that regard,  the Old Capital
Securities  provide,  among other  things,  that,  if a  registration  statement
relating to the  Exchange  Offer has not been filed by June 7, 1997 and declared
effective  by July 7,  1997,  the  Distribution  rate  borne by the Old  Capital
Securities commencing on July 8, 1997 will increase by 0.25% per annum until the
Exchange Offer is consummated.  Upon consummation of the Exchange Offer, holders
of  Old  Capital  Securities  will  not  be  entitled  to  any  increase  in the
Distribution  rate  thereon  or  any  further   registration  rights  under  the
Registration  Rights Agreement,  except under limited  circumstances.  See "Risk
Factors--Consequences  of a Failure to  Exchange  Old  Capital  Securities"  and
"Description of Old Securities."

The Exchange  Offer is not being made to, nor will the Trust accept  tenders for
exchange from,  holders of Old Capital  Securities in any  jurisdiction in which
the Exchange Offer or the acceptance thereof would not be in compliance with the
securities or blue sky laws of such jurisdiction.

Unless the context  requires  otherwise,  the term  "holder" with respect to the
Exchange Offer means any person in whose name the Old Capital  Securities are
registered on the books of the Trust or any other  person  who has  obtained  a
properly  completed  bond  power  from  the registered holder, or any person
whose Old Capital Securities are held of record by The Depository  Trust Company
("DTC") who desires to deliver such Old Capital Securities by book-entry
transfer at DTC.

<PAGE>

Pursuant to the Exchange Offer, the Company will exchange as soon as practicable
after the date  hereof,  the Old  Guarantee  for the New  Guarantee  and the Old
Junior Subordinated  Debentures,  in an amount  corresponding to the Old Capital
Securities  accepted for exchange,  for a like aggregate principal amount of the
New  Junior   Subordinated   Debentures.   The  New  Guarantee  and  New  Junior
Subordinated Debentures have been registered under the Securities Act.

Terms of the Exchange Offer

The Trust hereby offers,  upon the terms and subject to the conditions set forth
in this Prospectus and in the accompanying Letter of Transmittal, to exchange up
to $150,000,000  aggregate  Liquidation  Amount of New Capital  Securities for a
like aggregate Liquidation Amount of Old Capital Securities properly tendered on
or prior to the Expiration  Date and not properly  withdrawn in accordance  with
the  procedures  described  below.  The Trust  will  issue,  promptly  after the
Expiration  Date, an aggregate  Liquidation  Amount of up to $150,000,000 of New
Capital  Securities in exchange for a like principal  amount of outstanding  Old
Capital Securities  tendered and accepted in connection with the Exchange Offer.
Holders  may  tender  their  Old  Capital  Securities  in  whole or in part in a
Liquidation  Amount of not less than  $100,000 (100 Capital  Securities)  or any
integral multiple of $1,000  Liquidation Amount (one Capital Security) in excess
thereof.

The Exchange Offer is not conditioned upon any minimum Liquidation Amount of Old
Capital  Securities  being  tendered.   As  of  the  date  of  this  Prospectus,
$150,000,000  aggregate  Liquidation  Amount of the Old  Capital  Securities  is
outstanding.

Holders of Old  Capital  Securities  do not have any  appraisal  or  dissenters'
rights in connection with the Exchange Offer.  Old Capital  Securities which are
not tendered or are tendered  but not accepted in  connection  with the Exchange
Offer  will  remain   outstanding  and  be  entitled  to  the  benefits  of  the
Declaration,  but will not be entitled to any further  registration rights under
the Registration Rights Agreement, except under limited circumstances. See "Risk
Factors--Consequences  of a Failure to  Exchange  Old  Capital  Securities"  and
"Description of Old Securities."

If any tendered Old Capital  Securities are not accepted for exchange because of
an invalid  tender,  the  occurrence of certain other events set forth herein or
otherwise,  certificates for any such unaccepted Old Capital  Securities will be
returned,  without  expense,  to the tendering holder thereof promptly after the
Expiration Date.

Holders who tender Old Capital  Securities in connection with the Exchange Offer
will not be required to pay  brokerage  commissions  or fees or,  subject to the
instructions  in the Letter of  Transmittal,  transfer taxes with respect to the
exchange of Old Capital  Securities in connection with the Exchange  Offer.  The
Company will pay all charges and expenses,  other than certain  applicable taxes
described  below,  in  connection  with the  Exchange  Offer.  See  "--Fees  and
Expenses."

NEITHER  THE  COMPANY,  THE BOARD OF  DIRECTORS  OF THE  COMPANY  NOR ANY ISSUER
TRUSTEE  OF THE  TRUST  MAKES  ANY  RECOMMENDATION  TO  HOLDERS  OF OLD  CAPITAL
SECURITIES AS TO WHETHER TO TENDER OR REFRAIN FROM  TENDERING ALL OR ANY PORTION
OF THEIR OLD CAPITAL SECURITIES PURSUANT TO THE EXCHANGE OFFER. IN ADDITION,  NO
ONE HAS BEEN AUTHORIZED TO MAKE ANY SUCH RECOMMENDATION.  HOLDERS OF OLD CAPITAL
SECURITIES  MUST MAKE  THEIR OWN  DECISION  WHETHER  TO TENDER  PURSUANT  TO THE
EXCHANGE  OFFER AND, IF SO, THE  AGGREGATE  AMOUNT OF OLD CAPITAL  SECURITIES TO
TENDER BASED ON SUCH HOLDERS OWN FINANCIAL POSITION AND REQUIREMENTS.

The term "Expiration Date" means 5:00 p.m., New York City time, on , 1997 unless
the  Exchange  Offer is  extended by the Company or the Trust (in which case the
term "Expiration Date" shall mean the latest date and time to which the Exchange
Offer is extended).

The Company and the Trust expressly reserve the right in their sole and absolute
discretion, subject to applicable law, at any time and from time to time, (i) to
delay  the  acceptance  of the Old  Capital  Securities  for  exchange,  (ii) to
terminate the Exchange  Offer  (whether or not any Old Capital  Securities  have
theretofore been accepted for exchange) if the Trust determines, in its sole and
absolute  discretion,  that any of the events or  conditions  referred  to under
"--Conditions  to the  Exchange  Offer" have  occurred or exist or have not been
satisfied,  (iii) to extend the Expiration Date of the Exchange Offer and retain
all Old Capital  Securities  tendered  pursuant to the Exchange Offer,  subject,
however,  to the right of holders of Old Capital  Securities  to withdraw  their
tendered Old Capital  Securities as described under  "--Withdrawal  Rights," and
(iv) to waive any condition or otherwise  amend the terms of the Exchange  Offer
in any respect.  If the Exchange Offer is amended in a manner  determined by the
Company and the Trust to constitute a material change, or if the Company and the
Trust waive a material  condition  of the  Exchange  Offer,  the Company and the
Trust will promptly disclose such amendment by means of a prospectus  supplement
that will be distributed to the holders of the Old Capital  Securities,  and the
Company and the Trust will extend the Exchange  Offer to the extent  required by
Rule 14e-1 under the Exchange Act.

Any such  delay in  acceptance,  extension,  termination  or  amendment  will be
followed promptly by oral or written notice thereof to the Exchange Agent and by
making a public announcement  thereof,  and such  announcement  in the case of
an extension  will be made no later than 9:00 a.m.,  New York  City  time,  on
the next  business  day  after  the  previously scheduled  Expiration Date.
Without limiting the manner in which the Company and the Trust may choose to
make any public  announcement  and subject to applicable law, the Company and
the Trust shall have no obligation to publish, advertise or otherwise
communicate  any such  public  announcement  other  than by issuing a release to
an appropriate news agency.

Acceptance for Exchange and Issuance of New Capital Securities

Upon the terms and subject to the  conditions of the Exchange  Offer,  the Trust
will exchange,  and will issue to the Exchange Agent, New Capital Securities for
Old Capital  Securities  validly  tendered and not withdrawn  promptly after the
Expiration Date.

In all cases,  delivery of New Capital  Securities  in exchange  for Old Capital
Securities  tendered and accepted  for exchange  pursuant to the Exchange  Offer
will be made only after timely  receipt by the Exchange Agent of (i) Old Capital
Securities or a book-entry  confirmation of a book-entry transfer of Old Capital
Securities  into  the  Exchange  Agent's  account  at DTC,  (ii) the  Letter  of
Transmittal (or facsimile thereof),  properly completed and duly executed,  with
any required signature guarantees, and (iii) any other documents required by the
Letter of Transmittal.

The term "book-entry  confirmation"  means a timely confirmation of a book-entry
transfer of Old Capital Securities into the Exchange Agent's account at DTC.

Subject to the terms and  conditions  of the Exchange  Offer,  the Trust will be
deemed to have  accepted  for  exchange,  and  thereby  exchanged,  Old  Capital
Securities  validly  tendered and not  withdrawn as, if and when the Trust gives
oral or written notice to the Exchange  Agent of the Trust's  acceptance of such
Old Capital Securities for exchange pursuant to the Exchange Offer. The Exchange
Agent will act as agent for the Trust for the  purpose of  receiving  tenders of
Old Capital  Securities,  Letters of Transmittal and related  documents,  and as
agent for tendering holders for the purpose of receiving Old Capital Securities,
Letters of  Transmittal  and  related  documents  and  transmitting  New Capital
Securities  to validly  tendering  holders.  Such exchange will be made promptly
after the Expiration Date. If for any reason whatsoever, acceptance for exchange
or the exchange of any Old Capital Securities  tendered pursuant to the Exchange
Offer is delayed (whether before or after the Trust's acceptance for exchange of
Old Capital  Securities) or the Trust extends the Exchange Offer or is unable to
accept for exchange or exchange Old Capital Securities  tendered pursuant to the
Exchange Offer,  then, without prejudice to the Trust's rights set forth herein,
the Exchange Agent may, nevertheless, on behalf of the Trust and subject to Rule
14e-1(c) under the Exchange Act, retain tendered Old Capital Securities and such
Old  Capital  Securities  may not be  withdrawn  except to the extent  tendering
holders are  entitled to  withdrawal  rights as  described  under  "--Withdrawal
Rights."

Pursuant to the Letter of Transmittal,  a holder of Old Capital  Securities will
warrant  and  agree in the  Letter  of  Transmittal  that it has full  power and
authority to tender, exchange, sell, assign and transfer Old Capital Securities,
that the Trust will  acquire  good,  marketable  and  unencumbered  title to the
tendered  Old  Capital  Securities,  free and clear of all liens,  restrictions,
charges and encumbrances,  and the Old Capital Securities  tendered for exchange
are not subject to any adverse  claims or proxies.  The holder also will warrant
and agree  that it will,  upon  request,  execute  and  deliver  any  additional
documents deemed by the Trust or the Exchange Agent to be necessary or desirable
to complete  the  exchange,  sale,  assignment,  and transfer of the Old Capital
Securities tendered pursuant to the Exchange Offer.

Procedures for Tendering Old Capital Securities

VALID TENDER.  Except as set forth below, in order for Old Capital Securities to
be validly  tendered  pursuant to the Exchange  Offer, a properly  completed and
duly executed  Letter of Transmittal (or facsimile  thereof),  with any required
signature  guarantees and any other required documents,  must be received by the
Exchange Agent at one of its addresses set forth under  "--Exchange  Agent," and
either (i)  tendered  Old Capital  Securities  must be received by the  Exchange
Agent,  or (ii) such Old Capital  Securities  must be  tendered  pursuant to the
procedures for book-entry transfer set forth below and a book-entry confirmation
must be  received  by the  Exchange  Agent,  in each  case  on or  prior  to the
Expiration  Date, or (iii) the  guaranteed  delivery  procedures set forth below
must be complied with.

If less than all of the Old Capital Securities are tendered,  a tendering holder
should  fill in the  amount of Old  Capital  Securities  being  tendered  in the
appropriate box on the Letter of  Transmittal.  The entire amount of Old Capital
Securities  delivered to the Exchange Agent will be deemed to have been tendered
unless otherwise indicated.

THE METHOD OF DELIVERY OF CERTIFICATES,  THE LETTER OF TRANSMITTAL AND ALL OTHER
REQUIRED  DOCUMENTS IS AT THE OPTION AND SOLE RISK OF THE TENDERING HOLDER,  AND
DELIVERY WILL BE DEEMED MADE ONLY WHEN ACTUALLY  RECEIVED BY THE EXCHANGE AGENT.
IF DELIVERY IS BY MAIL,  REGISTERED  MAIL,  RETURN RECEIPT  REQUESTED,  PROPERLY
INSURED,  OR AN  OVERNIGHT  DELIVERY  SERVICE  IS  RECOMMENDED.  IN  ALL  CASES,
SUFFICIENT TIME SHOULD BE ALLOWED TO ENSURE TIMELY DELIVERY.

BOOK-ENTRY  TRANSFER.  The Exchange Agent will establish an account with respect
to the Old Capital  Securities at DTC for purposes of the Exchange  Offer within
two business days after the date of this Prospectus.  Any financial  institution
that is a participant in DTC's  book-entry  transfer  facility system may make a
book-entry  delivery  of the Old Capital  Securities  by causing DTC to transfer
such  Old  Capital  Securities  into  the  Exchange  Agent's  account  at DTC in
accordance with DTC's procedures for transfers.  However,  although  delivery of
Old Capital  Securities  may be effected  through  book-entry  transfer into the
Exchange  Agent's  account  at DTC,  the  Letter of  Transmittal  (or  facsimile
thereof),  properly  completed and duly  executed,  with any required  signature
guarantees  and any other required  documents,  must in any case be delivered to
and  received by the Exchange  Agent at its address set forth under  "--Exchange
Agent" on or prior to the Expiration Date, or the guaranteed  delivery procedure
set forth below must be complied with.

<PAGE>

DELIVERY OF DOCUMENTS TO DTC IN ACCORDANCE WITH DTC'S PROCEDURES DOES NOT
CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

SIGNATURE  GUARANTEES.  Certificates for the Old Capital  Securities need not be
endorsed and signature  guarantees on the Letter of Transmittal  are unnecessary
unless (a) a certificate for the Old Capital  Securities is registered in a name
other than that of the person  surrendering  the  certificate or (b) such holder
completes the box entitled "Special Issuance  Instructions" or "Special Delivery
Instructions"  in the  Letter of  Transmittal.  In the case of (a) or (b) above,
such  certificates  for  Old  Capital   Securities  must  be  duly  endorsed  or
accompanied by a properly executed bond power, with the endorsement or signature
on the bond power and on the Letter of Transmittal guaranteed by a firm or other
entity  identified  in Rule  17Ad-15  under  the  Exchange  Act as an  "eligible
guarantor  institution,"  including (as such terms are defined  therein):  (i) a
bank; (ii) a broker, dealer, municipal securities broker or dealer or government
securities broker or dealer;  (iii) a credit union;  (iv) a national  securities
exchange, registered securities association or clearing agency; or (v) a savings
association  that is a  participant  in a Securities  Transfer  Association  (an
"Eligible   Institution"),   unless  surrendered  on  behalf  of  such  Eligible
Institution. See Instruction 1 to the Letter of Transmittal.

GUARANTEED  DELIVERY.  If a holder  desires  to tender  Old  Capital  Securities
pursuant  to the  Exchange  Offer  and the  certificates  for such  Old  Capital
Securities  are not  immediately  available or time will not permit all required
documents to reach the Exchange Agent on or prior to the Expiration Date, or the
procedure for book-entry  transfer  cannot be completed on a timely basis,  such
Old Capital  Securities may  nevertheless be tendered,  provided that all of the
following guaranteed delivery procedures are complied with:

(1) such tenders are made by or through an Eligible Institution;

(2) a  properly  completed  and  duly  executed  Notice  of  Guaranteed
Delivery, substantially in the form accompanying the Letter of Transmittal, is
received by the Exchange Agent, as provided below, on or prior to the Expiration
Date; and

(3) the certificates (or a book-entry confirmation)  representing all tendered
Old Capital  Securities,  in proper  form for  transfer,  together  with a
properly completed and duly executed Letter of Transmittal (or facsimile
thereof),  with any required signature guarantees and any other documents
required by the Letter of  Transmittal,  are received by the Exchange Agent
within three New York Stock Exchange  trading days after the date of execution
of such Notice of  Guaranteed Delivery.

The Notice of Guaranteed  Delivery may be delivered by hand, or  transmitted  by
facsimile  or mail to the  Exchange  Agent and must  include a  guarantee  by an
Eligible Institution in the form set forth in such notice.

Notwithstanding  any  other  provision  hereof,  the  delivery  of  New  Capital
Securities  in exchange  for Old Capital  Securities  tendered  and accepted for
exchange  pursuant  to the  Exchange  Offer will in all cases be made only after
timely  receipt  by the  Exchange  Agent  of  Old  Capital  Securities,  or of a
book-entry  confirmation  with  respect to such Old  Capital  Securities,  and a
properly  completed  and duly  executed  Letter  of  Transmittal  (or  facsimile
thereof),  together  with  any  required  signature  guarantees  and  any  other
documents  required by the Letter of Transmittal.  Accordingly,  the delivery of
New Capital  Securities  might not be made to all tendering  holders at the same
time, and will depend upon when Old Capital Securities, book-entry confirmations
with respect to Old Capital Securities and other required documents are received
by the Exchange Agent.

The Trust's acceptance for exchange of Old Capital Securities  tendered pursuant
to any of the procedures  described  above will  constitute a binding  agreement
between  the  tendering  holder and the Trust upon the terms and  subject to the
conditions of the Exchange Offer.

DETERMINATION OF VALIDITY. All questions as to the form of documents,  validity,
eligibility  (including  time of receipt)  and  acceptance  for  exchange of any
tendered Old Capital Securities will be determined by the Company and the Trust,
in their sole discretion,  whose determination shall be final and binding on all
parties. The Company and the Trust reserve the absolute right, in their sole and
absolute discretion,  to reject any and all tenders determined by them not to be
in proper form or the acceptance of which,  or exchange for, may, in the opinion
of counsel to the Company and the Trust, be unlawful.  The Company and the Trust
also reserve the absolute right,  subject to applicable law, to waive any of the
conditions  of the  Exchange  Offer  as set  forth  under  "--Conditions  to the
Exchange  Offer" or any condition or  irregularity  in any tender of Old Capital
Securities  of any  particular  holder  whether  or not  similar  conditions  or
irregularities are waived in the case of other holders.

The  interpretation  by the Company and the Trust of the terms and conditions of
the Exchange Offer  (including the Letter of  Transmittal  and the  instructions
thereto) will be final and binding.  No tender of Old Capital Securities will be
deemed to have been validly made until all  irregularities  with respect to such
tender have been cured or waived. Neither the Company, the Trust, any affiliates
or assigns of the Company or the Trust,  the Exchange Agent nor any other person
shall  be  under  any duty to give any  notification  of any  irregularities  in
tenders or incur any liability for failure to give any such notification.

If any Letter of Transmittal, endorsement, bond power, power of attorney, or any
other  document  required by the Letter of  Transmittal  is signed by a trustee,
executor, administrator, guardian, attorney-in-fact, officer of a corporation or
other  person  acting in a fiduciary  or  representative  capacity,  such person
should so indicate when signing, and unless waived by the Company and the Trust,
proper  evidence  satisfactory  to the  Company  and the  Trust,  in their  sole
discretion, of such person's authority to so act must be submitted.

<PAGE>

A beneficial  owner of Old Capital  Securities that are held by or registered in
the name of a broker, dealer, commercial bank, trust company or other nominee or
custodian is urged to contact  such entity  promptly if such  beneficial  holder
wishes to participate in the Exchange Offer.

Resales of New Capital Securities

The  Trust is  making  the  Exchange  Offer for the New  Capital  Securities  in
reliance on the position of the staff of the Division of Corporation  Finance of
the Commission as set forth in certain  interpretive  letters addressed to third
parties in other transactions. However, neither the Company nor the Trust sought
its own interpretive  letter and there can be no assurance that the staff of the
Division  of  Corporation  Finance  of  the  Commission  would  make  a  similar
determination  with respect to the Exchange Offer as it has in such interpretive
letters to third  parties.  Based on these  interpretations  by the staff of the
Division  of  Corporation  Finance  of the  Commission,  and  subject to the two
immediately  following  sentences,  the Company and the Trust  believe  that New
Capital  Securities  issued  pursuant to this Exchange Offer in exchange for Old
Capital Securities may be offered for resale,  resold and otherwise  transferred
by a holder thereof (other than a holder who is a broker-dealer) without further
compliance with the  registration  and prospectus  delivery  requirements of the
Securities  Act,  provided that such New Capital  Securities are acquired in the
ordinary  course  of  such  holder's  business  and  that  such  holder  is  not
participating,  and has no  arrangement  or  understanding  with any  person  to
participate,  in a distribution  (within the meaning of the  Securities  Act) of
such New Capital Securities.  However,  any holder of Old Capital Securities who
is an  "affiliate"  of the Company or the Trust or who intends to participate in
the Exchange Offer for the purpose of distributing  New Capital  Securities,  or
any broker-dealer who purchased Old Capital  Securities from the Trust to resell
pursuant to Rule 144A or any other available exemption under the Securities Act,
(a) will not be able to rely on the interpretations of the staff of the Division
of  Corporation  Finance  of the  Commission  set  forth in the  above-mentioned
interpretive  letters,  (b) will not be permitted or entitled to tender such Old
Capital  Securities  in  the  Exchange  Offer  and  (c)  must  comply  with  the
registration  and  prospectus  delivery  requirements  of the  Securities Act in
connection with any sale or other transfer of such Old Capital Securities unless
such sale is made pursuant to an exemption from such requirements.  In addition,
as described below, if any broker-dealer  holds Old Capital Securities  acquired
for its own account as a result of market-making or other trading activities and
exchanges  such Old Capital  Securities  for New Capital  Securities,  then such
broker-dealer  must  deliver  a  prospectus  meeting  the  requirements  of  the
Securities Act in connection with any resales of such New Capital Securities.

Each  holder of Old  Capital  Securities  who  wishes to  exchange  Old  Capital
Securities for New Capital  Securities in the Exchange Offer will be required to
represent that (i) it is not an  "affiliate"  of the Company or the Trust,  (ii)
any New  Capital  Securities  to be  received  by it are being  acquired  in the
ordinary  course of its business,  (iii) it has no arrangement or  understanding
with any person to  participate  in a  distribution  (within  the meaning of the
Securities Act) of such New Capital Securities, and (iv) if such holder is not a
broker-dealer,  such holder is not engaged in, and does not intend to engage in,
a distribution  (within the meaning of the  Securities  Act) of such New Capital
Securities. In addition, the Company and the Trust may require such holder, as a
condition to such holder's  eligibility to participate in the Exchange Offer, to
furnish  to  the  Company  and  the  Trust  (or an  agent  thereof)  in  writing
information as to the number of "beneficial  owners" (within the meaning of Rule
13d-3 under the  Exchange  Act) on behalf of whom such holder  holds the Capital
Securities  to be exchanged  in the  Exchange  Offer.  Each  broker-dealer  that
receives  New Capital  Securities  for its own account  pursuant to the Exchange
Offer must acknowledge  that it acquired the Old Capital  Securities for its own
account as the result of  market-making  activities or other trading  activities
and must agree that it will deliver a prospectus meeting the requirements of the
Securities Act in connection with any resale of such New Capital Securities. The
Letter of  Transmittal  states  that by so  acknowledging  and by  delivering  a
prospectus,  a  broker-dealer  will  not  be  deemed  to  admit  that  it  is an
"underwriter"  within the meaning of the  Securities  Act. Based on the position
taken by the staff of the Division of  Corporation  Finance of the Commission in
the  interpretive  letters  referred to above, the Company and the Trust believe
that Participating  Broker-Dealers who acquired Old Capital Securities for their
own accounts as a result of market-making activities or other trading activities
may fulfill  their  prospectus  delivery  requirements  with  respect to the New
Capital Securities  received upon exchange of such Old Capital Securities (other
than Old  Capital  Securities  which  represent  an  unsold  allotment  from the
original  sale of the Old  Capital  Securities)  with a  prospectus  meeting the
requirements of the Securities Act, which may be the prospectus  prepared for an
exchange offer so long as it contains a description of the plan of  distribution
with respect to the resale of such New Capital Securities. Accordingly, this
Prospectus,  as it may be amended or supplemented from time to time, may be used
by a  Participating  Broker-Dealer  during  the  period  referred  to  below  in
connection with resales of New Capital  Securities  received in exchange for Old
Capital  Securities  where such Old  Capital  Securities  were  acquired by such
Participating  Broker-Dealer for its own account as a result of market-making or
other  trading  activities.  Subject  to  certain  provisions  set  forth in the
Registration  Rights Agreement,  the Company and the Trust have agreed that this
Prospectus,  as it may be amended or supplemented from time to time, may be used
by a Participating  Broker-Dealer in connection with resales of such New Capital
Securities  for a period ending  90-days after the  Expiration  Date (subject to
extension under certain limited  circumstances  described below) or, if earlier,
when all such New Capital Securities have been disposed of by such Participating
Broker-Dealer.   See   "Plan  of   Distribution."   However,   a   Participating
Broker-Dealer  who intends to use this  Prospectus in connection with the resale
of New  Capital  Securities  received in  exchange  for Old  Capital  Securities
pursuant to the  Exchange  Offer must notify the Company or the Trust,  or cause
the Company or the Trust to be  notified,  on or prior to the  Expiration  Date,
that it is a Participating Broker-Dealer.  Such notice may be given in the space
provided  for that purpose in the Letter of  Transmittal  or may be delivered to
the Exchange  Agent at one of the addresses  set forth herein under  "--Exchange
Agent." Any Participating  Broker-Dealer who is an "affiliate" of the Company or
the Trust may not rely on such  interpretive  letters  and must  comply with the
registration  and  prospectus  delivery  requirements  of the  Securities Act in
connection with any resale transaction.

In that regard,  each  Participating  Broker-Dealer  who  surrenders Old Capital
Securities  pursuant to the  Exchange  Offer will be deemed to have  agreed,  by
execution of the Letter of  Transmittal,  that,  upon receipt of notice from the
Company or the Trust of the occurrence of any event or the discovery of any fact
which  makes any  statement  contained  or  incorporated  by  reference  in this
Prospectus  untrue in any material  respect or which causes this  Prospectus  to
omit to  state a  material  fact  necessary  in  order  to make  the  statements
contained or incorporated  by reference  herein,  in light of the  circumstances
under which they were made, not misleading or of the occurrence of certain other
events  specified  in the  Registration  Rights  Agreement,  such  Participating
Broker-Dealer  will  suspend  the  sale of New  Capital  Securities  (or the New
Guarantee or the New Junior Subordinated Debentures,  as applicable) pursuant to
this Prospectus until the Company or the Trust has amended or supplemented  this
Prospectus to correct such  misstatement or omission and has furnished copies of
the amended or supplemented  Prospectus to such  Participating  Broker-Dealer or
the  Company  or the  Trust has given  notice  that the sale of the New  Capital
Securities (or the New Guarantee or the New Junior Subordinated  Debentures,  as
applicable)  may be  resumed,  as the case may be. If the  Company  or the Trust
gives such notice to suspend the sale of the New Capital  Securities (or the New
Guarantee or the New Junior Subordinated  Debentures,  as applicable),  it shall
extend  the  90-day  period   referred  to  above  during  which   Participating
Broker-Dealers are entitled to use this Prospectus in connection with the resale
of New  Capital  Securities  by the number of days  during  the period  from and
including  the date of the giving of such notice to and  including the date when
Participating  Broker-Dealers  shall  have  received  copies of the  amended  or
supplemented   Prospectus  necessary  to  permit  resales  of  the  New  Capital
Securities  or to and  including  the date on which the Company or the Trust has
given notice that the sale of New Capital  Securities  (or the New  Guarantee or
the New Junior  Subordinated  Debentures,  as applicable) may be resumed, as the
case may be.

Withdrawal Rights

Except as otherwise  provided herein,  tenders of Old Capital  Securities may be
withdrawn at any time on or prior to the Expiration Date.

In order for a  withdrawal  to be  effective  a written,  telegraphic,  telex or
facsimile  transmission  of such notice of withdrawal must be timely received by
the Exchange Agent at one of its addresses set forth under "--Exchange Agent" on
or prior to the Expiration  Date. Any such notice of withdrawal must specify the
name of the person who tendered the Old Capital Securities to be withdrawn,  the
aggregate  principal amount of Old Capital  Securities to be withdrawn,  and (if
certificates for such Old Capital Securities have been tendered) the name of the
registered holder of the Old Capital  Securities as set forth on the Old Capital
Securities,  if different  from that of the person who tendered such Old Capital
Securities.   If  Old  Capital  Securities  have  been  delivered  or  otherwise
identified to the Exchange Agent, then prior to the physical release of such Old
Capital Securities, the tendering holder must submit the serial numbers shown on
the particular  Old Capital  Securities to be withdrawn and the signature on the
notice of withdrawal  must be guaranteed by an Eligible  Institution,  except in
the case of Old  Capital  Securities  tendered  for the  account of an  Eligible
Institution.  If Old  Capital  Securities  have been  tendered  pursuant  to the
procedures for book-entry  transfer set forth in "--Procedures for Tendering Old
Capital  Securities,"  the notice of withdrawal must specify the name and number
of  the  account  at DTC to be  credited  with  the  withdrawal  of Old  Capital
Securities,  in which case a notice of withdrawal will be effective if delivered
to the Exchange Agent by written, telegraphic,  telex or facsimile transmission.
Withdrawals  of tenders of Old  Capital  Securities  may not be  rescinded.  Old
Capital  Securities  properly  withdrawn will not be deemed validly tendered for
purposes of the Exchange Offer,  but may be retendered at any subsequent time on
or prior to the  Expiration  Date by following any of the  procedures  described
above under "--Procedures for Tendering Old Capital Securities."

All  questions  as to the  validity,  form and  eligibility  (including  time of
receipt) of such withdrawal notices will be determined by the Trust, in its sole
discretion,  whose  determination  shall be final and  binding  on all  parties.
Neither the Company,  the Trust, any affiliates or assigns of the Company or the
Trust,  the Exchange  Agent nor any other person shall be under any duty to give
any notification of any  irregularities in any notice of withdrawal or incur any
liability for failure to give any such notification.  Any Old Capital Securities
which have been tendered but which are withdrawn  will be returned to the holder
thereof promptly after withdrawal.

Distributions on New Capital Securities

Holders of Old Capital  Securities whose Old Capital Securities are accepted for
exchange will not receive  Distributions on such Old Capital Securities and will
be deemed to have  waived the right to  receive  any  Distributions  on such Old
Capital  Securities  accumulated  from and after January 13, 1997.  Accordingly,
holders  of New  Capital  Securities  as of the record  date for the  payment of
Distributions  on July  1,  1997  will  be  entitled  to  receive  Distributions
accumulated from and after January 13, 1997.

Conditions to the Exchange Offer

Notwithstanding  any other provisions of the Exchange Offer, or any extension of
the Exchange Offer, the Company and the Trust will not be required to accept for
exchange,  or to  exchange,  any Old  Capital  Securities  for  any New  Capital
Securities,  and, as described  below, may terminate the Exchange Offer (whether
or not any Old Capital  Securities have  theretofore been accepted for exchange)
or may  waive  any  conditions  to or amend the  Exchange  Offer,  if any of the
following conditions have occurred or exists or have not been satisfied:

<PAGE>

(a) there shall occur a change in the  current  interpretation  by the staff of
the Commission  which  permits the New  Capital  Securities  issued  pursuant to
the Exchange Offer in exchange for Old Capital  Securities to be offered for
resale, resold and otherwise  transferred by holders thereof (other than
broker-dealers and any such holder which is an  "affiliate"  of the Company or
the Trust within the meaning of Rule 405 under the Securities  Act) without
compliance  with the registration and prospectus  delivery  provisions of the
Securities Act provided that such New Capital  Securities  are acquired in the
ordinary  course of such holders' business and such holders have no arrangement
or understanding with any person to participate in the distribution of such New
Capital Securities; or

(b) any law,  statute,  rule or  regulation  shall have been  adopted or enacted
which, in the judgment of the Company or the Trust, would reasonably be expected
to impair its ability to proceed with the Exchange Offer; or

(c) a stop  order  shall  have  been  issued  by  the  Commission  or any  state
securities authority suspending the effectiveness of the Registration  Statement
or proceedings  shall have been initiated or, to the knowledge of the Company or
the Trust,  threatened for that purpose any  governmental  approval has not been
obtained, which approval the Company or the Trust shall, in its sole discretion,
deem  necessary  for the  consummation  of the  Exchange  Offer as  contemplated
hereby.

If the Company or the Trust determines in its sole and absolute  discretion that
any of the foregoing events or conditions has occurred or exists or has not been
satisfied,  it may,  subject to applicable  law,  terminate  the Exchange  Offer
(whether or not any Old Capital  Securities have  theretofore  been accepted for
exchange) or may waive any such  condition  or otherwise  amend the terms of the
Exchange  Offer in any  respect.  If such  waiver  or  amendment  constitutes  a
material  change to the Exchange  Offer,  the Company or the Trust will promptly
disclose such waiver or amendment by means of a prospectus  supplement that will
be distributed to the registered  holders of the Old Capital Securities and will
extend  the  Exchange  Offer to the  extent  required  by Rule  14e-1  under the
Exchange Act.

The Company has agreed to pay the Exchange  Agent  reasonable and customary fees
for its services and will reimburse it for its reasonable out-of-pocket expenses
in connection  therewith.  The Company will also pay brokerage  houses and other
custodians,  nominees and  fiduciaries  the  reasonable  out-of-pocket  expenses

to the beneficial owners of Old Capital Securities, and in handling or tendering
for their customers.

Holders  who  tender  their Old  Capital  Securities  for  exchange  will not be
obligated to pay any transfer taxes in connection  therewith.  If, however,  New
Capital  Securities  are to be delivered to, or are to be issued in the name of,
any  person  other  than the  registered  holder of the Old  Capital  Securities
tendered, or if a transfer tax is imposed for any reason other than the exchange
of Old Capital Securities in connection with the Exchange Offer, then the amount
of any such transfer taxes (whether imposed on the registered holder or any
other persons) will be payable by the tendering holder.  If satisfactory
evidence of payment of such taxes or exemption therefrom is not submitted with
the Letter of Transmittal, the amount of such transfer taxes will be billed
directly to such tendering holder.

Neither the  Company nor the Trust will make any payment to brokers,  dealers or
other nominees soliciting acceptances of the Exchange Offer.

                         DESCRIPTION OF NEW SECURITIES

Description of New Capital Securities

Pursuant to the terms of the  Declaration,  the Trust has issued the Old Capital
Securities and the Common Securities and will issue the New Capital  Securities.
The New Capital Securities will represent preferred  beneficial interests in the
Trust  and  the  holders  of the New  Capital  Securities  and  the Old  Capital
Securities  will be  entitled  to a  preference  over the Common  Securities  in
certain  circumstances  with  respect to  Distributions  and amounts  payable on
redemption  of  the  Trust   Securities  or  liquidation   of  the  Trust.   See
"--Subordination of Common Securities." The Declaration has been qualified under
the Trust Indenture Act of 1939, as amended (the "Trust  Indenture  Act").  This
summary of certain  provisions of the New Capital Securities and the Declaration
does not  purport to be  complete  and is subject  to, and is  qualified  in its
entirety by reference to, all the provisions of the  Declaration,  including the
definitions therein of certain terms.

The Capital Securities (including the Old Capital Securities and the New Capital
Securities) are limited to $150,000,000  aggregate Liquidation Amount at any one
time outstanding. The Capital Securities will rank PARI PASSU, and payments will
be made  thereon  PRO  RATA,  with the Old  Capital  Securities  and the  Common
Securities  except as described under  "--Subordination  of Common  Securities."
Legal title to the Junior  Subordinated  Debentures will be held by the Property
Trustee in trust for the benefit of the holders of the  Capital  Securities  and
Common Securities. The New Guarantee will be a guarantee on a subordinated basis
but will not guarantee payment of Distributions or amounts payable on redemption
of the New Capital Securities or on liquidation of the Trust when the Trust does
not have funds on hand legally available for such payments.  See "Description of
the Guarantee."

<PAGE>

Distributions

Distributions on the New Capital Securities will be cumulative,  will accumulate
from January 13, 1997 and will be payable  semi-annually in arrears on January 1
and July 1 of each year, commencing July 1, 1997, at the annual rate of 8.71% of
the  Liquidation  Amount to the  holders of the New  Capital  Securities  on the
relevant record dates.  The record dates will be the dates fifteen days prior to
the relevant  Distribution Date (as defined herein). The amount of Distributions
payable for any period will be computed on the basis of a 360-day year of twelve
30-day months. In the event that any date on which  Distributions are payable on
the New Capital Securities is not a Business Day (as defined herein), payment of
the  Distributions  payable on such date will be made on the next succeeding day
that is a Business Day (and without any interest or other  payment in respect to
any such delay),  in each case with the same force and effect as if made on such
date (each  date on which  Distributions  are  payable  in  accordance  with the
foregoing,  a  "Distribution  Date").  A "Business Day" shall mean any day other
than a Saturday or a Sunday, or a day on which banking institutions in New York,
New York are authorized or required by law or executive order to remain closed.

So long as no Debenture  Event of Default shall have occurred and be continuing,
the  Company  will have the  right  under  the  Indenture  to elect to defer the
payment of interest on the Junior  Subordinated  Debentures  at any time or from
time to time for a period not exceeding 10 consecutive  semi-annual periods with
respect to each Extension  Period,  provided that no Extension Period may extend
beyond  the  Stated   Maturity  Date.   Upon  any  such  election,   semi-annual
Distributions on the New Capital Securities will be deferred by the Trust during
such  Extension  Period.  Distributions  to  which  holders  of the New  Capital
Securities  are  entitled  during  any such  Extension  Period  will  accumulate
additional  Distributions  thereon  at the  rate per  annum  of  8.71%  thereof,
compounded  semi-annually from the relevant Distribution Date, but not exceeding
the interest rate then accruing on the Junior Subordinated Debentures.  The term
"Distributions," as used herein shall include any such additional Distributions.

During any such Extension Period,  the Company may extend such Extension Period,
provided that such extension  does not cause such Extension  Period to exceed 10
consecutive  semi-annual  periods or to extend beyond the Stated  Maturity Date.
Upon the termination of any such Extension Period and the payment of all amounts
then due,  and subject to the  foregoing  limitations,  the Company may elect to
begin a new Extension Period.  The Company must give the Property  Trustee,  the
Administrative  Trustees and the Debenture Trustee notice of its election of any
Extension  Period or any extension  thereof at least five Business Days prior to
the  earlier of (i) the date the  Distributions  on the New  Capital  Securities
would  have  been  payable  except  for the  election  to begin or  extend  such
Extension Period and (ii) the date the  Administrative  Trustees are required to
give  notice  to any  securities  exchange  or to  holders  of the  New  Capital
Securities of the record date or the date such Distributions are payable, but in
any event not less than five Business  Days prior to such record date.  There is
no  limitation  on the  number of times that the  Company  may elect to begin an
Extension  Period.  See  "Description of New Junior  Subordinated  Debentures --
Option  to Extend  Interest  Payment  Date"  and  "Certain  Federal  Income  Tax
Consequences -- Interest Income and Original Issue Discount."


<PAGE>

During any such  Extension  Period,  the  Company may not (i) declare or pay any
dividends  or  distributions  on,  or  redeem,  purchase,  acquire,  or  make  a
liquidation  payment with respect to, any of the Company's  capital stock (which
includes common and preferred stock) or (ii) make any payment of principal of or
premium,  if any,  or  interest  on or  repay,  repurchase  or  redeem  any debt
securities of the Company (including Other Debentures) that rank pari passu with
or junior in right of  payment to the Junior  Subordinated  Debentures  or (iii)
make any guarantee  payments with respect to any guarantee by the Company of the
debt securities of any subsidiary of the Company (including Other Guarantees) if
such guarantee ranks pari passu with or junior in right of payment to the Junior
Subordinated Debentures (other than (a) dividends or distributions in shares of,
or options,  warrants or rights to subscribe  for or purchase  shares of, common
stock of the Company,  (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  Guarantee,  (d) as a result  of a
reclassification of the Company's capital stock or the exchange or conversion of
one class, or series of the Company's  capital stock for another class or series
of the Company's  capital  stock,  (e) the purchase of  fractional  interests in
shares of the  Company's  capital stock  pursuant to the  conversion or exchange
provisions of such capital stock or the security  being  converted or exchanged,
and (f)  purchases or issuances  of common stock in  connection  with any of the
Company's stock option,  stock  purchase,  stock loan or other benefit plans for
its  directors,   officers  or  employees  or  any  of  the  Company's  dividend
reinvestment  plans,  in each case as now existing or hereafter  established  or
amended).

Although the Company may in the future  exercise its option to defer payments of
interest on the Junior Subordinated Debentures,  the Company has no such current
intention.

The revenue of the Trust  available for  distribution  to holders of the Capital
Securities will be limited to payments under the Junior Subordinated  Debentures
in which the Trust will invest the  proceeds  from the  issuance and sale of the
Trust Securities.  See "Description of New Junior  Subordinated  Debentures." If
the  Company  does  not  make  interest  payments  on  the  Junior  Subordinated
Debentures,   the  Property  Trustee  will  not  have  funds  available  to  pay
Distributions on the Capital Securities. The payment of Distributions (if and to
the extent the Trust has funds on hand legally available for the payment of such
Distributions) will be guaranteed by the Company on a limited basis as set forth
herein under "Description of the Guarantee."

Conditional Right to Advance Maturity and Special Event Redemption

If a Tax Event (as defined herein) occurs,  then the Company will have the right
(i) prior to the  termination of the Trust,  to advance the Stated Maturity Date
of the Junior Subordinated Debentures to the minimum extent required in order to
allow for payments of interest in respect of the Junior Subordinated  Debentures
to continue to be tax deductible,  but in no event shall the resulting  maturity
of the Junior  Subordinated  Debentures  be less than 20 years from  January 13,
1997, or (ii) to terminate the Trust (if not previously  terminated) and advance
the Stated  Maturity Date of the Junior  Subordinated  Debentures to the minimum
extent required in order to allow for the payments of interest in respect of the
Junior  Subordinated  Debentures  to  continue to be tax  deductible  for United
States federal income tax purposes, but in no event shall the resulting maturity
of the Junior  Subordinated  Debentures  be less than 40 years from  January 13,
1997.  In either  case,  such  maturity  date shall be advanced  only if, in the
opinion of counsel to the Company  experienced in such matters,  after advancing
the maturity date, interest paid on the Junior  Subordinated  Debentures will be
deductible  for federal  income tax purposes  (the action  referred to in either
clause  (i) or (ii) above  being  referred  to herein as a "Tax  Event  Maturity
Advancement").

If a Tax Event  occurs and in the opinion of counsel to the Company  experienced
in such matters,  there would in all cases, after effecting a Tax Event Maturity
Advancement,  be more than an insubstantial risk that an Adverse Tax Consequence
(as defined herein) would continue to exist, or, if an Investment  Company Event
(as defined herein) occurs, then the Company will have the right, within 90 days
following the occurrence of such Tax Event or Investment  Company Event,  as the
case may be, to redeem the Junior  Subordinated  Debentures in whole (but not in
part) in the  manner set forth  under  "Description  of New Junior  Subordinated
Debentures  --  Conditional   Right  to  Advance   Maturity  and  Special  Event
Prepayment,"  and  therefore  to cause a  mandatory  redemption  of the  Capital
Securities prior to the Stated Maturity Date (the circumstances  under which the
Company  has the  right to so  redeem  the  Junior  Subordinated  Debentures  in
connection with a Tax Event being referred to


<PAGE>

herein as a "Conditional Tax Redemption Event"). Each of a Conditional Tax
Redemption Event or an Investment Company Event are sometimes referred to herein
as a "Special Event."

Redemption

Upon the repayment on the Stated Maturity Date or prepayment prior to the Stated
Maturity  Date of the Junior  Subordinated  Debentures,  the proceeds  from such
repayment or  prepayment  shall be applied by the  Property  Trustee to redeem a
Like Amount (as defined  below) of the Trust  Securities,  upon not less than 30
nor more than 60 days' notice of a date of redemption (the "Redemption Date") at
the applicable  Redemption Price, which shall be equal to (i) in the case of the
repayment of the Junior Subordinated Debentures on the Stated Maturity Date, the
Maturity Redemption Price (equal to the principal of and accrued interest on the
Junior Subordinated Debentures),  (ii) in the case of the optional prepayment of
the Junior  Subordinated  Debentures  upon the occurrence and  continuation of a
Special  Event prior to January 1, 2007,  the  Special  Event  Redemption  Price
(equal  to  the  Special  Event  Prepayment  Price  in  respect  of  the  Junior
Subordinated Debentures) and (iii) in the case of the optional prepayment of the
Junior  Subordinated  Debentures  on or after  January  1,  2007,  the  Optional
Redemption  Price  (equal to the  Optional  Prepayment  Price in  respect of the
Junior  Subordinated  Debentures).  See "Description of New Junior  Subordinated
Debentures  --  Optional  Prepayment"  and " --  Conditional  Right  to  Advance
Maturity and Special Event Prepayment."

"Like Amount"  means (i) with respect to a redemption  of the Trust  Securities,
Trust  Securities  having a Liquidation  Amount equal to the principal amount of
Junior  Subordinated  Debentures to be paid in  accordance  with their terms and
(ii) with respect to a distribution of Junior  Subordinated  Debentures upon the
liquidation  of the Trust,  Junior  Subordinated  Debentures  having a principal
amount equal to the Liquidation  Amount of the Trust Securities of the holder to
whom such Junior Subordinated Debentures are distributed.

The Company will have the option to prepay the Junior  Subordinated  Debentures,
(i) in whole or in part, on or after January 1, 2007, at the applicable Optional
Prepayment  Price  and (ii) in  whole  but not in part,  at any  time,  upon the
occurrence  of a Special  Event prior to January 1, 2007,  at the Special  Event
Prepayment Price.

Liquidation of the Trust and Distribution of Junior Subordinated Debentures

The Company  will have the right at any time to dissolve the Trust and cause the
Junior  Subordinated  Debentures to be  distributed  to the holders of the Trust
Securities  in  liquidation  of the  Trust.  Such  right is  conditioned  on the
Administrative Trustees having received an opinion of counsel to the effect that
such distribution will not be a taxable event to holders of Capital Securities.

The Trust shall  automatically  dissolve and its affairs  shall be wound up upon
the  first to occur  of:  (i)  certain  events  of  bankruptcy,  dissolution  or
liquidation of the Company; (ii) the distribution of a Like Amount of the Junior
Subordinated Debentures to the holders of the Trust Securities,  if the Company,
as Sponsor,  has given written direction to the Property Trustee to dissolve the
Trust (which direction is optional and, except as described above, wholly within
the discretion of the Company, as Sponsor) and provided that the distribution is
conditioned  on the  receipt of an  opinion  of counsel to the effect  that such
distribution will not be a taxable event to holders of Capital Securities; (iii)
redemption of all of the Trust  Securities as described  under " --  Redemption"
above;  (iv) expiration of the term of the Trust;  and (v) the entry of an order
for the dissolution of the Trust by a court of competent jurisdiction.

If a  dissolution  occurs as described in clause (i),  (ii),  (iv) or (v) of the
preceding  paragraph,  the  Trust  shall  be  liquidated  by the  Administrative
Trustees  as  expeditiously  as  the  Administrative  Trustees  determine  to be
possible by distributing,  after satisfaction of liabilities to creditors of the
Trust as provided by  applicable  law, to the holders of the Trust  Securities a
Like Amount of the Junior Subordinated  Debentures,  unless such distribution is
determined by the Property  Trustee not to be  practicable,  in which event such
holders  will be  entitled  to receive  out of the  assets of the Trust  legally
available for  distribution  to holders,  after  satisfaction  of liabilities to
creditors  of the Trust as provided by  applicable  law, an amount  equal to the
aggregate of the Liquidation  Amount plus  accumulated and unpaid  Distributions
thereon  to  the  date  of  payment   (such   amount   being  the   "Liquidation
Distribution"). If the Liquidation Distribution can be paid only in part because
the Trust has insufficient  assets on hand legally  available to pay in full the
aggregate Liquidation Distribution, then the amounts payable directly by the


<PAGE>


Trust on the Capital Securities and the Common Securities shall be paid on a pro
rata  basis,  except that if a Debenture  Event of Default has  occurred  and is
continuing,  the  Capital  Securities  shall  have a  priority  over the  Common
Securities.   See  "  --  Subordination  of  Common  Securities."  If  an  early
dissolution  occurs as  described in clause (v) above,  the Junior  Subordinated
Debentures will be subject to optional prepayment,  in whole but not in part, on
or after January 1, 2007.

If the Company elects not to prepay the Junior Subordinated  Debentures prior to
maturity in accordance with their terms and either elects not to or is unable to
liquidate the Trust and distribute the Junior Subordinated Debentures to holders
of the Trust Securities,  the Trust Securities will remain outstanding until the
repayment of the Junior Subordinated Debentures on the Stated Maturity Date.

After the liquidation date is fixed for any distribution of Junior  Subordinated
Debentures to holders of the Trust Securities,  (i) the Trust Securities will no
longer be deemed to be  outstanding,  (ii) each  registered  global  certificate
representing  Trust  Securities  and held by DTC or its nominee  will  receive a
registered   global   certificate  or  certificates   representing   the  Junior
Subordinated  Debentures to be delivered  upon such  distribution  and (iii) any
certificates  representing  Trust Securities not held by DTC or its nominee will
be deemed to represent Junior Subordinated  Debentures having a principal amount
equal to the Liquidation  Amount of such Trust  Securities,  and bearing accrued
and  unpaid   interest  in  an  amount  equal  to  the  accumulated  and  unpaid
Distributions on such Trust Securities until such  certificates are presented to
the  Administrative  Trustees or their  agent for  cancellation,  whereupon  the
Company will issue to such holder,  and the Debenture Trustee will authenticate,
a certificate representing such Junior Subordinated Debentures.

There can be no assurance as to the market prices for the Capital  Securities or
the Junior  Subordinated  Debentures that may be distributed in exchange for the
Trust  Securities if a dissolution  and  liquidation of the Trust were to occur.
Accordingly, the Capital Securities that an investor may purchase, or the Junior
Subordinated  Debentures  that the  investor  may  receive  on  dissolution  and
liquidation of the Trust, may trade at a discount to the price that the investor
paid to purchase the Capital Securities.

Redemption Procedures

If applicable,  Trust Securities shall be redeemed at the applicable  Redemption
Price with the proceeds from the contemporaneous  repayment or prepayment of the
Junior Subordinated Debentures. Any redemption of Trust Securities shall be made
and the applicable Redemption Price shall be payable on the Redemption Date only
to the extent that the Trust has funds legally available for the payment of such
applicable Redemption Price. See also " -- Subordination of Common Securities."

If the Trust gives a notice of redemption in respect of the Capital  Securities,
then, by 12:00 noon, New York City time, on the  Redemption  Date, to the extent
funds are legally available,  with respect to the Capital Securities held by DTC
or its nominees,  the Property  Trustee will deposit  irrevocably with DTC funds
sufficient to pay the applicable Redemption Price. See " -- Form,  Denomination,
Book-Entry Procedures and Transfer." With respect to the Capital Securities held
in  certificated  form,  the Property  Trustee,  to the extent funds are legally
available,  will  irrevocably  deposit  with the  paying  agent for the  Capital
Securities funds sufficient to pay the applicable Redemption Price and will give
such paying agent  irrevocable  instructions and authority to pay the applicable
Redemption  Price to the holders  thereof upon  surrender of their  certificates
evidencing  the Capital  Securities.  See " -- Payment and Paying Agency" below.
Distributions payable on or prior to the Redemption Date shall be payable to the
holders of such Capital  Securities on the relevant record dates for the related
Distribution  Dates.  If notice of  redemption  shall  have been given and funds
deposited as  required,  then upon the date of such  deposit,  all rights of the
holders of the Capital Securities will cease, except the right of the holders of
the Capital  Securities to receive the applicable  Redemption Price, but without
interest on such Redemption  Price, and the Capital  Securities will cease to be
outstanding.  In the event that any Redemption Date of Capital Securities is not
a Business Day, then the applicable  Redemption  Price payable on such date will
be paid on the next  succeeding  day that is a  Business  Day (and  without  any
interest or other  payment in respect of any such delay),  except that,  if such
Business Day falls in the next calendar  year,  such payment will be made on the
immediately  preceding Business Day. In the event that payment of the applicable
Redemption  Price is  improperly  withheld or refused and not paid either by the
Trust  or  by  the  Company   pursuant  to  the  Guarantee  as  described  under
"Description of


<PAGE>


the Guarantee,"  Distributions on Capital  Securities called for redemption will
continue to accumulate at the then  applicable  rate,  from the Redemption  Date
originally established by the Trust to the date such applicable Redemption Price
is actually  paid, in which case the actual  payment date will be the Redemption
Date for purposes of calculating the applicable Redemption Price.

Subject to applicable law (including,  without limitation, United States federal
securities  law), the Company or its  subsidiaries may at any time and from time
to time purchase outstanding Capital Securities by tender, in the open market or
by private agreement.

Notice  of any  redemption  will be mailed at least 30 days but not more than 60
days prior to the  Redemption  Date to each  holder of Trust  Securities  at its
registered  address.  Unless the Company  defaults in payment of the  applicable
Prepayment Price on, or in the repayment of, the Junior Subordinated Debentures,
on and after the Redemption Date Distributions will cease to accrue on the Trust
Securities called for redemption.

Subordination of Common Securities

Payment of Distributions on, and the Redemption Price of, the Capital Securities
and the Common  Securities,  as applicable,  shall be made pro rata based on the
Liquidation Amount of the Capital  Securities and Common  Securities;  provided,
however,  that if on any Distribution  Date or Redemption Date a Debenture Event
of Default shall have occurred and be continuing, no payment of any Distribution
on, or  applicable  Redemption  Price of, any of the Common  Securities,  and no
other payment on account of the redemption,  liquidation or other acquisition of
the  Common  Securities,  shall be made  unless  payment  in full in cash of all
accumulated  and  unpaid   Distributions  on  all  of  the  outstanding  Capital
Securities for all Distribution  periods  terminating on or prior thereto or, in
the case of Capital  Securities called for redemption on a Redemption Date on or
prior thereto, the full amount of the Redemption Price therefor, shall have been
made or provided  for, and all funds  available to the  Property  Trustee  shall
first be applied  to the  payment  in full in cash of all  Distributions  on, or
Redemption Price of, the Capital Securities then due and payable.

In the case of any  Event of  Default,  the  Company  as  holder  of the  Common
Securities  will be deemed to have waived any right to act with  respect to such
Event of  Default  until the  effect of such  Event of  Default  shall have been
cured, waived or otherwise eliminated.  Until any such Event of Default has been
so cured, waived or otherwise eliminated,  the Property Trustee shall act solely
on behalf of the  holders  of the  Capital  Securities  and not on behalf of the
Company as holder of the Common Securities,  and only the holders of the Capital
Securities  will have the right to direct the  Property  Trustee to act on their
behalf.

Events of Default; Notice

The occurrence of a Debenture  Event of Default (see  "Description of New Junior
Subordinated  Debentures -- Debenture Events of Default")  constitutes an "Event
of Default" under the Declaration.

Within five Business Days after the occurrence of any Event of Default  actually
known to the Property  Trustee,  the Property  Trustee shall transmit  notice of
such  Event  of  Default  to  the  holders  of  the  Capital   Securities,   the
Administrative  Trustees  and the  Company,  as  Sponsor,  unless  such Event of
Default  shall have been cured or  waived.  The  Company,  as  Sponsor,  and the
Administrative  Trustees are required to file annually with the Property Trustee
a  certificate  as to  whether  or not  they  are in  compliance  with  all  the
conditions and covenants applicable to them under the Declaration.

If a Debenture  Event of Default has  occurred  and is  continuing,  the Capital
Securities shall have a preference over the Common Securities as described under
" -- Liquidation  of  the  Trust  and  Distribution  of  Junior   Subordinated
Debentures" and "-- Subordination of Common Securities" above.

Removal of Issuer Trustees

Unless a Debenture  Event of Default shall have occurred and be continuing,  any
Issuer  Trustee  may  be  removed  at  any  time  by the  holder  of the  Common
Securities. If a Debenture Event of Default has occurred and is continuing,  the
Property  Trustee  and the  Delaware  Trustee may be removed at such time by the
holders  of  a  majority  in  Liquidation  Amount  of  the  outstanding  Capital
Securities. In no event will the holders of the Capital


<PAGE>


Securities   have  the  right  to  vote  to  appoint,   remove  or  replace  the
Administrative  Trustees,  which  voting  rights are vested  exclusively  in the
Company as the holder of the Common Securities.  No resignation or removal of an
Issuer  Trustee and no  appointment  of a successor  trustee  shall be effective
until the acceptance of appointment by the successor  trustee in accordance with
the provisions of the Declaration.

Merger or Consolidation of Issuer Trustees

Any corporation  into which the Property  Trustee,  the Delaware  Trustee or any
Administrative  Trustee that is not a natural  person may be merged or converted
or with which it may be  consolidated,  or any  corporation  resulting  from any
merger,  conversion  or  consolidation  to which such Issuer  Trustee shall be a
party, or any corporation  succeeding to all or substantially  all the corporate
trust  business of such Issuer  Trustee,  shall be the  successor of such Issuer
Trustee  under the  Declaration,  provided such  corporation  shall be otherwise
qualified and eligible.

Mergers, Conversions, Consolidations, Amalgamations or Replacements of the Trust

The Trust may not merge or convert with or into, consolidate,  amalgamate, or be
replaced  by, or  convey,  transfer  or lease its  properties  and  assets as an
entirety or  substantially  as an entirety to any  corporation  or other Person,
except as  described  below.  The Trust may, at the request of the  Company,  as
Sponsor, with the consent of the Administrative Trustees but without the consent
of the  Property  Trustee,  the  Delaware  Trustee  or  holders  of the  Capital
Securities,  merge or  convert  with or  into,  consolidate,  amalgamate,  or be
replaced  by or  convey,  transfer  or lease  its  properties  and  assets as an
entirety or  substantially as an entirety to a trust organized as such under the
laws of any State; provided, that (i) such successor entity either (a) expressly
assumes  all of the  obligations  of  the  Trust  with  respect  to the  Capital
Securities or (b) substitutes for the Capital Securities other securities having
substantially  the  same  terms  as  the  Capital   Securities  (the  "Successor
Securities")  so long as the Successor  Securities  rank the same as the Capital
Securities  rank in priority  with respect to  distributions  and payments  upon
liquidation,  redemption and otherwise,  (ii) the Company  expressly  appoints a
trustee of such  successor  entity  possessing the same powers and duties as the
Property Trustee with respect to the Junior Subordinated  Debentures,  (iii) the
Successor Securities are listed, or any Successor Securities will be listed upon
notification  of  issuance,   on  any  national  securities  exchange  or  other
organization on which the Capital  Securities are then listed, if any, (iv) such
merger,  conversion,  consolidation,   amalgamation,   replacement,  conveyance,
transfer or lease does not cause the Capital Securities (including any Successor
Securities) to be downgraded by any  nationally  recognized  statistical  rating
organization,   (v)  such  merger,  conversion,   consolidation,   amalgamation,
replacement, conveyance, transfer or lease does not adversely affect the rights,
preferences and privileges of the holders of the Capital  Securities  (including
any Successor  Securities) in any material respect (other than with respect to a
dilution of such  holder's  interest  in the new  entity),  (vi) such  successor
entity has a purpose identical to that of the Trust, (vii) prior to such merger,
conversion,  consolidation,  amalgamation,  replacement, conveyance, transfer or
lease, the Company has received an opinion from independent counsel to the Trust
experienced  in such  matters to the effect  that (a) such  merger,  conversion,
consolidation, amalgamation, replacement, conveyance, transfer or lease does not
adversely  affect the rights,  preferences  and privileges of the holders of the
Capital Securities  (including any Successor Securities) in any material respect
(other  than with  respect to a dilution  of such  holder's  interest in the new
entity), and (b) following such merger, conversion, consolidation, amalgamation,
replacement, conveyance, transfer or lease, neither the Trust nor such successor
entity  will  be  required  to  register  as an  investment  company  under  the
Investment  Company Act of 1940, as amended (the "Investment  Company Act"), and
(viii) the Company or any permitted successor or assignee owns all of the common
securities of such  successor  entity and  guarantees  the  obligations  of such
successor entity under the Successor  Securities at least to the extent provided
by the Guarantee.  Notwithstanding  the foregoing,  the Trust shall not,  except
with  the  consent  of  holders  of  100% in  Liquidation  Amount  of the  Trust
Securities,  consolidate,  amalgamate,  merge or  convert  with or  into,  or be
replaced  by or  convey,  transfer  or lease  its  properties  and  assets as an
entirety or substantially as an entirety to any other entity or permit any other
entity to consolidate,  amalgamate, merge or convert with or into, or replace it
if  such   consolidation,   amalgamation,   merger,   conversion,   replacement,
conveyance,  transfer or lease would cause the Trust or the successor entity not
to be  classified  as a grantor  trust for  United  States  federal  income  tax
purposes.

Voting Rights; Amendment of the Declaration

Except as provided  below and under " -- Mergers,  Conversions,  Consolidations,
Amalgamations  or  Replacements  of the  Trust"  above and  "Description  of the
Guarantee -- Amendments and Assignment" and as otherwise required by law and the
Declaration, the holders of the Capital Securities will have no voting rights.

The  Declaration  may be amended from time to time by the Company and the Issuer
Trustees, without the consent of the holders of the Trust Securities (i) to cure
any ambiguity,  correct or supplement any provisions in the Declaration that may
be inconsistent with any other provision of the Declaration, or to add any other
provisions with respect to matters or questions  arising under the  Declaration,
which shall not be inconsistent with the other provisions of the Declaration, or
(ii) to modify,  eliminate or add to any  provisions of the  Declaration to such
extent as shall be  necessary  to ensure that the Trust will be  classified  for
United States  federal  income tax purposes as a grantor trust at all times that
any Trust  Securities  are  outstanding  or to ensure that the Trust will not be
required to register as an "investment  company"  under the  Investment  Company
Act;  provided,  however,  that in the case of clause (i), such action shall not
adversely  affect in any  material  respect the  interests of the holders of the
Trust  Securities,  and any amendments of the Declaration shall become effective
when  notice  thereof  is given to the  holders  of the  Trust  Securities.  The
Declaration  may be amended by the Issuer  Trustees and the Company (i) with the
consent of holders  representing a majority (based upon  Liquidation  Amount) of
the outstanding Trust  Securities,  and (ii) upon receipt by the Issuer Trustees
of an opinion of counsel to the effect that such  amendment  or the  exercise of
any power granted to the Issuer  Trustees in accordance with such amendment will
not affect the  Trust's  status as a grantor  trust for  United  States  federal
income tax  purposes or the  Trust's  exemption  from  status as an  "investment
company" under the  Investment  Company Act; (it being  understood  that the New
Capital Securities and any Old Capital Securities which remain outstanding after
consummation  of the  Exchange  Offer will vote  together as a single  class for
purposes  of  determining  whether  holders  of  the  requisite   percentage  in
outstanding  Liquidation  Amount thereof have taken certain actions or exercised
certain rights under the Declaration) provided that, without the consent of each
holder of Trust Securities, the Declaration may not be amended to (i) change the
amount or timing of any  Distribution  or other  payment on or in respect of the
Trust Securities or otherwise adversely affect the amount of any Distribution or
other  payment  required to be made in respect of the Trust  Securities  as of a
specified  date or (ii)  restrict the right of a holder of Trust  Securities  to
institute suit for the enforcement of any such payment on or after such date.

So long as any Junior Subordinated  Debentures are held by the Property Trustee,
the  Issuer  Trustees  shall  not (i)  direct  the  time,  method  and  place of
conducting any proceeding for any remedy available to the Debenture Trustee,  or
execute any trust or power conferred on the Property Trustee with respect to the
Junior  Subordinated  Debentures,  (ii) waive  certain past  defaults  under the
Indenture,  (iii)  exercise  any  right to  rescind  or annul a  declaration  of
acceleration  of the  maturity  of the  principal  of  the  Junior  Subordinated
Debentures or (iv) consent to any amendment,  modification or termination of the
Indenture or the Junior  Subordinated  Debentures,  where such consent  shall be
required,  without, in each case, obtaining the prior approval of the holders of
a  majority  in  Liquidation  Amount  of  all  outstanding  Capital  Securities;
provided,  however,  that where a consent under the Indenture  would require the
consent of each holder of Junior  Subordinated  Debentures  affected thereby, no
such consent shall be given by the Property  Trustee  without the prior approval
of each holder of the Capital  Securities.  The Issuer Trustees shall not revoke
any action  previously  authorized  or  approved by a vote of the holders of the
Capital  Securities  except by  subsequent  vote of such  holders.  The Property
Trustee shall notify each holder of Capital  Securities of any notice of default
with respect to the Junior Subordinated Debentures. In addition to obtaining the
foregoing approvals of such holders of the Capital  Securities,  prior to taking
any of the foregoing  actions,  the Issuer  Trustees  shall obtain an opinion of
counsel  experienced  in such  matters to the effect  that the Trust will not be
classified as an association  taxable as a corporation for United States federal
income tax purposes on account of such action.

Any required approval of holders of Capital Securities may be given at a meeting
of such holders  convened for such purpose or pursuant to written  consent.  The
Property  Trustee will cause a notice of any meeting at which holders of Capital
Securities  are entitled to vote,  or of any matter upon which action by written
consent of such holders is to be taken,  to be given to each holder of record of
Capital Securities in the manner set forth in the Declaration.


<PAGE>


No vote or consent of the holders of Capital Securities will be required for the
Trust to redeem  and  cancel  the  Capital  Securities  in  accordance  with the
Declaration.

Notwithstanding  that holders of the Capital  Securities are entitled to vote or
consent  under any of the  circumstances  described  above,  any of the  Capital
Securities  that are owned by the Company,  the Issuer Trustees or any affiliate
of the  Company or any  Issuer  Trustees  shall,  for  purposes  of such vote or
consent, be treated as if they were not outstanding.

Form, Denomination, Book-Entry Procedures and Transfer

The New Capital Securities  initially will be represented by one or more Capital
Securities  certificates in registered,  global form (collectively,  the "Global
Capital  Securities").  The Global  Capital  Securities  will be deposited  upon
issuance with the Property  Trustee as custodian for DTC, in New York, New York,
and registered in the name of DTC or its nominee,  in each case for credit to an
account of a direct or indirect participant in DTC as described below.

Except as set forth below, the Global Capital Securities may be transferred,  in
whole and not in part,  only to another  nominee of DTC or to a successor of DTC
or its nominee. Beneficial interests in the Global Capital Securities may not be
exchanged  for Capital  Securities  in  certificated  form except in the limited
circumstances   described  below.  See  " -- Exchange  of  Book-Entry  Capital
Securities for Certificated Capital Securities".

Other Capital Securities will be issued only in registered,  certificated (i.e.,
non-global)  form. Other Capital  Securities may not be exchanged for beneficial
interests in any Global Capital  Securities except in the limited  circumstances
described  below.  See  " --  Exchange  of  Book-Entry  Capital  Securities  for
Certificated Capital Securities".

Depositary Procedures

DTC has advised the Trust and the Company  that DTC is a  limited-purpose  trust
company  created  to  hold  securities  for  its   participating   organizations
(collectively,   the   "Participants")  and  to  facilitate  the  clearance  and
settlement of  transactions in those  securities  between  Participants  through
electronic book-entry changes in accounts of its Participants.  The Participants
include  securities  brokers and  dealers  (including  the Initial  Purchasers),
banks, trust companies,  clearing  corporations and certain other organizations.
Access  to DTC's  system  is also  available  to other  entities  such as banks,
brokers,  dealers and trust companies that clear through or maintain a custodial
relationship  with a Participant,  either directly or indirectly  (collectively,
the "Indirect Participants").  Persons who are not Participants may beneficially
own securities held by or on behalf of DTC only through the  Participants or the
Indirect Participants. The ownership interest and transfer of ownership interest
of each  actual  purchaser  of each  security  held by or on  behalf  of DTC are
recorded on the records of the Participants and Indirect Participants.

DTC has also  advised the Trust and the  Company  that,  pursuant to  procedures
established by it, (i) upon deposit of the Global Capital  Securities,  DTC will
credit the accounts of  Participants  designated by the Initial  Purchasers with
portions of the  Liquidation  Amount of the Global  Capital  Securities and (ii)
ownership of such interests in the Global Capital  Securities  will be shown on,
and the transfer of ownership  thereof will be effected  only  through,  records
maintained by DTC (with respect to the  Participants) or by the Participants and
the Indirect  Participants (with respect to other owners of beneficial interests
in the Global Capital Securities).

Except as described below, owners of beneficial  interests in the Global Capital
Securities will not have Capital  Securities  registered in their name, will not
receive physical  delivery of Capital  Securities in certificated  form and will
not be considered the registered owners or holders thereof under the Declaration
for any purpose.

Payments in respect of the Global Capital Security registered in the name of DTC
or its nominee will be payable by the Property Trustee to DTC in its capacity as
the registered holder under the Declaration. Under the terms of the Declaration,
the  Property  Trustee  will  treat  the  persons  in whose  names  the  Capital
Securities,  including  the Global  Capital  Securities,  are  registered as the
owners  thereof for the purpose of receiving  such  payments and for any and all
other purposes  whatsoever.  Consequently,  neither the Property Trustee nor any
agent  thereof  has or will have any  responsibility  or  liability  for (i) any
aspect of DTC's records or any Participant's or Indirect  Participant's  records
relating to or payments made on account of beneficial ownership interests in the
Global Capital Securities,  or for maintaining,  supervising or reviewing any of
DTC's records or any Participant's or Indirect Participant's records relating to
the beneficial  ownership interests in the Global Capital Securities or (ii) any
other  matter  relating  to  the  actions  and  practices  of  DTC or any of its
Participants or Indirect Participants. DTC has advised the Trust and the Company
that its current practice,  upon receipt of any payment in respect of securities
such as the  Capital  Securities,  is to credit  the  accounts  of the  relevant
Participants  with the payment on the payment date, in amounts  proportionate to
their respective  holdings in Liquidation Amount of beneficial  interests in the
relevant  security  as shown on the  records  of DTC  unless  DTC has  reason to
believe  it will not  receive  payment on such  payment  date.  Payments  by the
Participants and the Indirect  Participants to the beneficial  owners of Capital
Securities will be governed by standing instructions and customary practices and
will be the responsibility of the Participants or the Indirect  Participants and
will not be the  responsibility of DTC, the Property  Trustee,  the Trust or the
Company.  Neither  the Trust or the  Company nor the  Property  Trustee  will be
liable  for any  delay  by DTC or any of its  Participants  in  identifying  the
beneficial  owners of the Capital  Securities,  and the Trust or the Company and
the Property Trustee may  conclusively  rely on and will be protected in relying
on instructions from DTC or its nominee for all purposes.

<PAGE>

Beneficial  interests  in the  Global  Capital  Securities  will  trade in DTC's
Same-Day Funds  Settlement  System and secondary market trading activity in such
interests will therefore settle in immediately  available funds,  subject in all
cases to the rules and procedures of DTC and its participants.

DTC has advised the Trust and the Company that it will take any action permitted
to be taken by a holder of Capital  Securities  only at the  direction of one or
more  Participants  to whose  account with DTC  interests in the Global  Capital
Securities  are credited and only in respect of such portion of the  Liquidation
Amount of the Capital  Securities as to which such  Participant or  Participants
has or have given such direction. However, if there is an Event of Default under
the  Declaration,  DTC  reserves  the  right  to  exchange  the  Global  Capital
Securities  for  legended  Capital   Securities  in  certificated  form  and  to
distribute such Capital Securities to its Participants.

The  information in this section  concerning  DTC and its book-entry  system has
been  obtained  from  sources  that the  Trust  and the  Company  believe  to be
reliable,  but neither the Trust nor the Company  takes  responsibility  for the
accuracy thereof.

Exchange of Book-Entry Capital Securities for Certificated Capital Securities

A  Global  Capital  Security  is  exchangeable  for New  Capital  Securities  in
registered  certificated  form if (i)  DTC (x)  notifies  the  Trust  that it is
unwilling or unable to continue as Depositary  for the Global  Capital  Security
and the Trust thereupon fails to appoint a successor  Depositary  within 90 days
or (y) has ceased to be a clearing  agency  registered  under the Exchange  Act,
(ii) the  Company in its sole  discretion  elects to cause the  issuance  of the
Capital  Securities in certificated  form or (iii) there shall have occurred and
be  continuing  an Event of Default or any event which after  notice or lapse of
time or both would be an Event of Default  under the  Declaration.  In addition,
beneficial  interests  in  a  Global  Capital  Security  may  be  exchanged  for
certificated New Capital  Securities upon request but only upon at least 20 days
prior  written  notice given to the  Property  Trustee by or on behalf of DTC in
accordance with customary  procedures.  In all cases,  certificated  New Capital
Securities  delivered in exchange for any Global Capital  Security or beneficial
interests  therein will be registered  in the names,  and issued in any approved
denominations,  requested by or on behalf of the Depositary (in accordance  with
its  customary  procedures)  and will bear the legend  referred to in "Notice to
Investors",  unless the Property Trustee determines otherwise in compliance with
applicable law.


<PAGE>


Payment and Paying Agency

Payments in respect of the Capital  Securities held in global form shall be made
to the Depositary, which shall credit the relevant accounts at the Depositary on
the applicable  Distribution  Dates or in respect of the Capital Securities that
are not held by the  Depositary,  such payments shall be made by check mailed to
the address of the holder  entitled  thereto as such address shall appear on the
register.  The paying agent (the "Paying Agent") shall initially be the Property
Trustee and any co-paying agent chosen by the Property Trustee and acceptable to
the Administrative Trustees and the Company. The Paying Agent shall be permitted
to resign as Paying  Agent upon 30 days written  notice to the Property  Trustee
and the Company.  In the event that the Property  Trustee shall no longer be the
Paying Agent, the Administrative Trustees shall appoint a successor (which shall
be a bank or trust  company  acceptable to the  Administrative  Trustees and the
Company) to act as Paying Agent.

Registrar and Transfer Agent

The Property  Trustee will act as registrar  and transfer  agent for the Capital
Securities.

Registration of transfers of the New Capital Securities will be effected without
charge  by or on  behalf  of the  Trust  but  upon  payment  of any tax or other
governmental  charges  that may be imposed in  connection  with any  transfer or
exchange.  The Trust will not be required to register or cause to be  registered
the  transfer  of the New  Capital  Securities  after they have been  called for
redemption.

Information Concerning the Property Trustee

The Property  Trustee,  other than during the occurrence  and  continuance of an
Event of Default, undertakes to perform only such duties as are specifically set
forth in the  Declaration  and,  after such Event of Default,  must exercise the
same degree of care and skill as a prudent  person would  exercise or use in the
conduct of his or her own  affairs.  Subject  to this  provision,  the  Property
Trustee is under no obligation to exercise any of the powers vested in it by the
Declaration  at the  request  of any  holder  of Trust  Securities  unless it is
offered  reasonable  indemnity against the costs,  expenses and liabilities that
might be incurred  thereby.  The  Property  Trustee is not required to expend or
risk its own  funds or  otherwise  incur  personal  financial  liability  in the
performance  of its duties if repayment or adequate  indemnity is not reasonably
assured to the Property Trustee.  From time to time, the Property Trustee and/or
its  affiliates  extend  credit and may  provide  investment  banking  and other
financial services to the Company. See " Markel Capital Trust I."

Miscellaneous

The  Administrative  Trustees are authorized and directed to conduct the affairs
of and to  operate  the Trust in such a way that the Trust will not be deemed to
be an  "investment  company"  required  to be  registered  under the  Investment
Company Act of 1940,  as amended or classified  as an  association  taxable as a
corporation for United States federal income tax purposes and so that the Junior
Subordinated  Debentures  will be treated as  indebtedness  of the  Company  for
United States federal income tax purposes.  In this connection,  the Company and
the Administrative  Trustees are authorized to take any action, not inconsistent
with applicable  law, the certificate of trust of the Trust or the  Declaration,
that the Company and the  Administrative  Trustees determine in their discretion
to be necessary or desirable for such purposes,  as long as such action does not
materially   adversely  affect  the  interests  of  the  holders  of  the  Trust
Securities.

Holders of the Trust Securities have no preemptive or similar rights.

The Trust may not borrow money,  issue debt,  execute mortgages or pledge any of
its assets.

               DESCRIPTION OF NEW JUNIOR SUBORDINATED DEBENTURES

The  Old  Junior  Subordinated   Debentures  were  issued  and  the  New  Junior
Subordinated  Debentures will be issued under an Indenture, as supplemented from
time to time (as so supplemented, the "Indenture"),  between the Company and The
Chase Manhattan Bank, as trustee (the  "Debenture  Trustee").  The Indenture has
been qualified  under the Trust Indenture Act. This summary of certain terms and
provisions of the Junior  Subordinated  Debentures  and the  Indenture  does not
purport to be complete,  and where reference is made to particular provisions of
the Indenture, such provisions, including the definitions of certain terms, some
of which are not otherwise  defined  herein,  are qualified in their entirety by
reference to all of the  provisions of the Indenture and those terms made a part
of the Indenture by the Trust Indenture Act.

Concurrently with the issuance of the Capital Securities, the Trust invested the
proceeds thereof,  together with the  consideration  paid by the Company for the
Common Securities,  in Old Junior Subordinated Debentures issued by the Company.
Pursuant  to the  Exchange  Offer,  the  Company  will  exchange  the Old Junior
Subordinated  Debentures,   in  an  amount  corresponding  to  the  Old  Capital
Securities  accepted for exchange,  for a like aggregate principal amount of the
New Junior Subordinated Debentures as soon as practicable after the date hereof.
The New Junior Subordinated  Debentures will bear interest at the annual rate of
8.71% of the  principal  amount  thereof,  payable  semi-annually  in arrears on
January 1 and July 1 of each year (each, an "Interest Payment Date"), commencing
July 1, 1997,  to the  person  in whose  name  each  Junior  Subordinated
Debenture  is registered,  subject to certain exceptions, at the close of
business on the date fifteen days prior to the relevant  Interest  Payment Date.
It is  anticipated that,  until the  liquidation,  if any, of the Trust,  each

<PAGE>

Junior  Subordinated Debenture  will be held in the name of the  Property
Trustee  in trust  for the benefit of the holders of the Trust  Securities.  The
amount of interest payable for any period will be computed on the basis of a
360-day year of twelve  30-day months.  In the event that any date on which
interest  is payable on the Junior Subordinated  Debentures  is not a Business
Day,  then  payment of the interest payable on such date will be made on the
next  succeeding day that is a Business Day (and  without any  interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding  calendar year, such payment shall be made on the
immediately  preceding  Business Day, in each case with  the  same  force  and
effect  as if made on the  date  such  payment  was originally payable. Accrued
interest that is not paid on the applicable Interest Payment Date will bear
additional  interest on the amount thereof (to the extent permitted  by  law) at
the  rate  per  annum  of  8.71%  thereof,   compounded semi-annually.  The term
"interest",  as used herein,  shall include semi-annual interest  payments,
interest on semi-annual  interest  payments not paid on the applicable  Interest
Payment Date and Additional Sums (as defined  herein),  as applicable.

The Junior Subordinated Debentures will be issued in denominations of $1,000 and
integral multiples thereof.  The Junior  Subordinated  Debentures will mature on
January 1, 2046 (the "Stated Maturity Date"), except as described below.

The New Junior Subordinated  Debentures will rank pari passu with the Old Junior
Subordinated  Debentures  and all Other  Debentures  and will be  unsecured  and
subordinate  and rank junior in right of payment to the extent and in the manner
set forth in the Indenture to all Senior  Indebtedness.  See " -- Subordination"
below.  The Company is a holding company and almost all of the operating  assets
of the Company and its consolidated subsidiaries are owned by such subsidiaries.
The Company  relies  primarily on dividends from such  subsidiaries  to meet its
obligations.  The  Company is a legal  entity  separate  and  distinct  from its
subsidiaries.  The  principal  sources of the  Company's  income are  dividends,
interest and fees from its  subsidiaries.  As a holding  company,  the Company's
ability to meet debt service  obligations and pay operating  expenses depends on
receipt of  sufficient  funds from its direct  and  indirect  subsidiaries.  The
inability of the Company's direct and indirect  subsidiaries to pay dividends to
the Company in an amount  sufficient  to meet debt service  obligations  and pay
operating  expenses would have a material  adverse effect on the Company and the
Trust.  The payment of dividends by the  Company's  subsidiaries  without  prior
regulatory  approval is subject to restrictions  set forth in the insurance laws
and  regulations of Virginia,  Illinois,  Delaware,  New Jersey,  California and
Arizona,  the states of domicile of the Company's  insurance  subsidiaries.  The
Company  currently does not expect such  regulatory  requirements  to impair its
ability to meet interest  payment  obligations and to pay operating  expenses in
the future.  However,  the Company can give no assurance  that dividends will be
declared or paid by its  subsidiaries.  As of December 31, 1995,  the  Company's
direct and indirect  insurance  subsidiaries had sufficient capital and earnings
to pay up to $36.2 million of dividends to the Company during 1996 without prior
regulatory  approval.  In  addition,  payment of dividends to the Company by the
insurance  subsidiaries is subject to ongoing review by insurance regulators and
is  subject  to  various  statutory  limitations  and in  certain  circumstances
requires approval by insurance regulatory authorities.  Because the Company is a
holding company,  the right of the Company to participate in any distribution of
assets of any subsidiary upon such subsidiary's liquidation or reorganization or
otherwise, is subject to the prior claims of creditors of the subsidiary, except
to the  extent  the  Company  may itself be  recognized  as a  creditor  of that
subsidiary.  Accordingly, the Junior Subordinated Debentures will be effectively
subordinated   to  all  existing  and  future   liabilities   of  the  Company's
subsidiaries,  and holders of Junior Subordinated Debentures should look only to
the assets of the Company for payments on the Junior Subordinated Debentures. In
addition,  because many of the Company's  subsidiaries  are insurance  companies
subject to  regulatory  control  by various  state  insurance  departments,  the
ability of such  subsidiaries  to pay  dividends  to the Company  without  prior
regulatory approval is limited by applicable laws and regulations. The Indenture
does not limit the  incurrence or issuance of other secured or unsecured debt of
the Company,  including  Senior  Indebtedness,  or other  obligations.  See " --
Subordination" below.

Form, Registration and Transfer

If the Junior  Subordinated  Debentures  are  distributed  to the holders of the
Trust Securities,  the Junior Subordinated  Debentures may be represented by one
or more global certificates  registered in the name of Cede & Co. as the nominee
of DTC. The depositary  arrangements for such Junior Subordinated Debentures are
expected  to be  substantially  similar  to  those  in  effect  for the  Capital
Securities.   For  a  description  of  DTC  and  the  terms  of  the  depositary
arrangements  relating to payments,  transfers,  voting rights,  redemptions and
other notices and other  matters,  see  "Description  of New Securities -- Form,
Denomination, Book-Entry Procedures and Transfer."

Payment and Paying Agents

Payment  of  principal  of and  premium,  if any,  and any  interest  on  Junior
Subordinated  Debentures will be made at the office of the Debenture  Trustee in
The City of New York or at the office of such Paying  Agent or Paying  Agents as
the Company may  designate  from time to time,  except that at the option of the
Company  payment  of any  interest  may be made,  except  in the case of  Junior
Subordinated  Debentures  in global form,  (i) by check mailed to the address of
the Person  entitled  thereto as such  address  shall appear in the register for
Junior  Subordinated  Debentures or (ii) by transfer to an account maintained by
the Person entitled thereto as specified in such register,  provided that proper
transfer instructions have been received by the relevant Record Date. Payment of
any interest on any Junior Subordinated  Debenture will be made to the Person in
whose name such Junior  Subordinated  Debenture  is  registered  at the close of
business on the Record Date for such interest,  except in the case of defaulted
interest.  The Company may at any time designate additional Paying Agents or
rescind the designation of any Paying Agent;  however the Company will at all
times be required to maintain a Paying Agent in each Place of Payment for the
Junior Subordinated Debentures.

Any moneys  deposited  with the Debenture  Trustee or any Paying Agent,  or then
held by the Company in trust,  for the payment of the  principal of and premium,
if any, or interest on any Junior Subordinated Debenture and remaining unclaimed
for two years after such  principal and premium,  if any, or interest has become
due and payable shall,  at the request of the Company,  be repaid to the Company
and the holder of such Junior Subordinated Debenture shall thereafter look, as a
general unsecured creditor, only to the Company for payment thereof.

Option to Extend Interest Payment Date

So long as no Debenture  Event of Default has occurred  and is  continuing,  the
Company  will have the right under the  Indenture at any time during the term of
the Junior Subordinated  Debentures to defer the payment of interest at any time
or from time to time for a period  not  exceeding  10  consecutive,  semi-annual
periods with respect to each Extension Period, provided that no Extension Period
may extend beyond the Stated  Maturity Date. At the end of an Extension  Period,
the  Company  must pay all  interest  then  accrued  and unpaid  (together  with
interest then accrued at the annual rate of 8.71%, compounded semi-annually,  to
the extent permitted by applicable law).  During an Extension  Period,  interest
will  continue  to accrue and  holders of Junior  Subordinated  Debentures  (and
holders of the Trust Securities while Trust Securities are outstanding)  will be
required to accrue interest income for United States federal income tax purposes
prior to the receipt of cash  attributable to such income.  See "Certain Federal
Income Tax Consequences -- Interest Income and Original Issue Discount."

During any such  Extension  Period,  the  Company may not (i) declare or pay any
dividends  or  distributions  on,  or  redeem,  purchase,  acquire,  or  make  a
liquidation  payment with respect to, any of the Company's  capital stock (which
includes  common and  preferred  stock) or (ii) make any  payment of  principal,
interest  or  premium,  if any,  on or  repay,  repurchase  or  redeem  any debt
securities of the Company  (including any Other Debentures) that rank pari passu
with or junior in right of  payment  to the Junior  Subordinated  Debentures  or
(iii) make any  guarantee  payments with respect to any guarantee by the Company
of the debt  securities of any  subsidiary of the Company  (including  any Other
Guarantees)  if such  guarantee  ranks  pari  passu  with or  junior in right of
payment to the Junior  Subordinated  Debentures  (other  than (a)  dividends  or
distributions  in shares of or options,  warrants or rights to subscribe  for or
purchase  shares of,  common  stock of the  Company,  (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
Guarantee,  (d) as a result of a reclassification of the Company's capital stock
or the exchange or conversion  of one class or series of the  Company's  capital
stock for  another  class or  series of the  Company's  capital  stock,  (e) the
purchase  of  fractional  interests  in shares of the  Company's  capital  stock
pursuant to the  conversion or exchange  provisions of such capital stock or the
security being converted or exchanged,  and (f) purchases or issuances of common
stock under any of the Company's  stock option,  stock  purchase,  stock loan or
other  benefit  plans for its  directors,  officers or  employees  or any of the
Company's dividend reinvestment plans, in each case as now existing or hereafter
established or amended).

Prior to the termination of any such Extension  Period,  the Company may further
extend such Extension  Period,  provided that such extension does not cause such
Extension  Period to  exceed 10  consecutive  semi-annual  periods  or to extend
beyond the Stated  Maturity  Date.  Upon the  termination  of any such Extension
Period and the payment of all amounts then due on any Interest Payment Date, the
Company  may  elect  to  begin a new  Extension  Period,  subject  to the  above
requirements.  No interest shall be due and payable during an Extension  Period,
except at the end  thereof.  The Company  must give the  Property  Trustee,  the
Administrative  Trustees and the Debenture Trustee notice of its election of any
Extension Period (or an extension  thereof) at least five Business Days prior to
the earlier of (i) the date the Distributions on the Trust Securities would have
been payable except for the election to begin or extend such Extension Period or
(ii) the date the  Administrative  Trustees  are  required to give notice to any
securities  exchange or to holders of Capital  Securities  of the record date or
the date such  Distributions  are  payable,  but in any event not less than five
Business Days prior to such record date. The Debenture Trustee shall give notice
of the  Company's  election  to begin or  extend a new  Extension  Period to the
holders of the Capital Securities. There is no limitation on the number of times
that the Company may elect to begin an Extension Period.

to the percentage of the outstanding principal amount of the Junior Subordinated
Debentures  specified below, plus, in each case, accrued interest thereon to the
date of prepayment if redeemed during the 12-month period beginning January 1 of

Conditional Right to Advance Maturity and Special Event Prepayment

If a Tax Event (as defined herein) occurs,  then the Company will have the right
(i) prior to the  termination of the Trust,  to advance the Stated Maturity Date
of the Junior Subordinated Debentures to the minimum extent required in order to
allow for the  payments  of  interest  in  respect  of the  Junior  Subordinated
Debentures to continue to be tax deductible, but in no event shall the resulting
maturity  of the  Junior  Subordinated  Debentures  be less  than 20 years  from
January 13, 1997, or (ii) to terminate the Trust (if not previously  terminated)
and advance the Stated  Maturity Date of the Junior  Subordinated  Debentures to
the minimum  extent  required in order to allow for the  payments of interest in
respect of the Junior Subordinated  Debentures to continue to be tax deductible,
but  in no  event  shall  the  resulting  maturity  of the  Junior  Subordinated
Debentures  be less than 40 years from  January 13, 1997.  In either case,  such
maturity  date  shall be  advanced  only if, in the  opinion  of  counsel to the
Company experienced in such matters, after advancing the maturity date, interest
paid on the Junior Subordinated Debentures will be deductible for federal income
tax purposes  (the action  referred to in either  clause (i) or (ii) above being
referred to herein as a "Tax Event Maturity Advancement").

If a Special Event (as defined below) shall occur and be continuing prior to the
Initial  Optional  Prepayment  Date, the Company may, at its option,  prepay the
Junior Subordinated  Debentures in whole (but not in part) at any time within 90
days of the  occurrence  of such  Special  Event,  at a  prepayment  price  (the
"Special  Event  Prepayment  Price")  equal  to the  greater  of (i) 100% of the
principal  amount of such  Junior  Subordinated  Debentures  or (ii) the sum, as
determined by a Quotation  Agent, of the present values of the principal  amount
and  premium   payable  with  respect  to  an  optional   redemption  of  Junior
Subordinated  Debentures on January 1, 2007, together with scheduled payments of
interest on the Junior  Subordinated  Debentures from the prepayment date to and
including the Initial Optional Prepayment Date discounted to the prepayment date
on a  semi-annual  basis  (assuming a 360-day year  consisting  of twelve 30-day
months) at the Adjusted  Treasury  Rate,  plus, in each case,  accrued  interest
thereon to the date of prepayment.

"Special  Event" means a  Conditional  Tax  Redemption  Event (as defined  under
"Description of the New Securities -- Conditional  Right to Advance Maturity and
Special Event Redemption") or an Investment Company Event, as the case may be.

"Tax  Event"  means the  receipt  by the  Company  and the Trust of an  opinion,
requested by the Company,  of counsel  experienced in such matters to the effect
that,  as a result  of any  amendment  to, or change  (including  any  announced
prospective  change) in, the laws or any  regulations  thereunder  of the United
States or any political  subdivision or taxing authority thereof or therein,  or
as a result of any official administrative written decision or


<PAGE>


pronouncement  or  judicial  decision  interpreting  or  applying  such  laws or
regulations,  which  amendment or change is effective or such  pronouncement  or
decision  is  made  on or  after  January  13,  1997,  there  is  more  than  an
insubstantial  risk that (i) the Trust is, or will be within 90 days of the date
of such  opinion,  subject to United States  federal  income tax with respect to
income received or accrued on the Junior Subordinated Debentures,  (ii) interest
payable by the Company on the Junior  Subordinated  Debentures is not, or within
90 days of the date of such opinion will not be,  deductible by the Company,  in
whole or in part, for United States  federal  income tax purposes,  or (iii) the
Trust is, or will be within 90 days of the date of such opinion, subject to more
than a de minimis amount of other taxes,  duties or other  governmental  charges
(each of the  circumstances  referred to in clauses (i), (ii) and (iii) being an
"Adverse Tax Consequence").

"Investment  Company  Event"  means that the  Company  and the Trust  shall have
received  an  opinion,  requested  by the  Company,  of counsel  experienced  in
practice under the Investment  Company Act of 1940, as amended (the  "Investment
Company Act"),  to the effect that, as a result of the occurrence of a change in
law or  regulation  or a  change  in  interpretation  or  application  of law or
regulation by any legislative  body,  court,  governmental  agency or regulatory
authority  (a "Change in  Investment  Company  Act Law"),  there is more than an
insubstantial  risk  that the  Trust  is or will be  considered  an  "investment
company" which is required to be registered  under the  Investment  Company Act,
which  Change in  Investment  Company Act Law becomes  effective on or after the
Issue Date.

"Adjusted  Treasury Rate" means,  with respect to any prepayment  date, the rate
per  annum  equal  to  the  semi-annual  equivalent  yield  to  maturity  of the
Comparable Treasury Issue,  calculated using a price for the Comparable Treasury
Issue  (expressed  as a  percentage  of  its  principal  amount)  equal  to  the
Comparable  Treasury  Price for such  prepayment  date,  calculated on the third
Business Day preceding the prepayment  date, plus in each case (a) 1.25% if such
prepayment  date occurs on or prior to the first  anniversary of the issuance of
the Capital Securities offered hereby and (b) 0.50% in all other cases.

"Comparable  Treasury Issue" means the United States Treasury  security selected
by the Quotation Agent as having a maturity  comparable to the remaining term to
the Stated  Maturity Date of the Junior  Subordinated  Debentures  that would be
utilized,  at the time of selection and in accordance  with customary  financial
practice,  in pricing new issues of  corporate  debt  securities  of  comparable
maturity to the remaining term of the Junior Subordinated Debentures.

"Quotation Agent" means the Reference  Treasury Dealer appointed by the Company.
"Reference  Treasury Dealer" means: (i) Donaldson,  Lufkin & Jenrette Securities
Corporation and respective successors;  provided, however, that if the foregoing
shall cease to be a primary U.S.  Government  securities dealer in New York City
(a "Primary  Treasury  Dealer"),  the Company shall substitute  therefor another
Primary Treasury Dealer;  and (ii) any other Primary Treasury Dealer selected by
the Debenture Trustee after consultation with the Company.

"Comparable  Treasury Price" means, with respect to any prepayment date, (i) the
average of the bid and asked prices for the Comparable Treasury Issue (expressed
in each case as a percentage of its principal  amount) on the third Business Day
preceding such prepayment  date, as set forth in the daily  statistical  release
(or any successor release) published by the Federal Reserve Bank of New York and
designated  "Composite 3:30 p.m. Quotations for U.S.  Government  Securities" or
(ii) if such  release (or any  successor  release) is not  published or does not
contain  such prices on such  Business  Day,  (A) the  average of the  Reference
Treasury Dealer Quotations for such prepayment date, after excluding the highest
and lowest such Reference  Treasury Dealer  Quotations,  or (B) if the Debenture
Trustee obtains fewer than three such Reference Treasury Dealer Quotations,  the
average of all such Quotations.

"Reference  Treasury Dealer  Quotations"  means,  with respect to each Reference
Treasury  Dealer and any  prepayment  date,  the average,  as  determined by the
Debenture Trustee, of the bid and asked prices for the Comparable Treasury Issue
(expressed  in each case as a  percentage  of its  principal  amount)  quoted in
writing to the Debenture Trustee by such Reference Treasury Dealer at 5:00 p.m.,
New York City time, on the third Business Day preceding such prepayment date.

"Additional  Sums" means such  additional  amounts as may be  necessary in order
that the  amount  of  Distributions  then due and  payable  by the  Trust on the
outstanding Capital Securities and Common Securities shall not


<PAGE>


be reduced as a result of any  additional  taxes,  duties or other  governmental
charges to which the Trust has become subject as a result of a Tax Event.

Notice  of any  prepayment  will be mailed at least 30 days but not more than 60
days before the redemption date to each holder of Junior Subordinated Debentures
to be prepaid at its registered address.  Unless the Company defaults in payment
of the prepayment  price,  on and after the prepayment  date interest  ceases to
accrue on such Junior Subordinated Debentures called for prepayment.

If  the  Trust  is  required  to pay  any  additional  taxes,  duties  or  other
governmental  charges  as a  result  of a Tax  Event,  the  Company  will pay as
additional amounts on the Junior Subordinated Debentures the Additional Sums.

Certain Covenants of the Company

The  Company  will  also  covenant  that it will  not,  (i)  declare  or pay any
dividends  or  distributions  on,  or  redeem,  purchase,  acquire,  or  make  a
liquidation  payment with respect to, any of the Company's  capital stock (which
includes  common and  preferred  stock) or (ii) make any  payment of  principal,
interest  or  premium,  if any,  on or repay or  repurchase  or redeem  any debt
securities of the Company (including Other Debentures) that rank pari passu with
or junior in right of  payment to the Junior  Subordinated  Debentures  or (iii)
make any guarantee  payments with respect to any guarantee by the Company of the
debt  securities  of  any  subsidiary  of the  Company  (including  under  Other
Guarantees) if such guarantee  ranks pari passu or junior in right of payment to
the Junior Subordinated Debentures (other than (a) dividends or distributions in
shares of, or options,  warrants or rights to subscribe  for or purchase  shares
of, common stock of the Company, (b) any declaration of a dividend in connection
with the implementation of a stockholder's 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 Guarantee,  (d) as a result of a
reclassification of the Company's capital stock or the exchange or conversion of
one class or series of the  Company's  capital stock for another class or series
of the Company's  capital  stock,  (e) the purchase of  fractional  interests in
shares of the  Company's  capital stock  pursuant to the  conversion or exchange
provisions of such capital stock or the security  being  converted or exchanged,
and (f)  purchases or issuances  of common stock in  connection  with any of the
Company's stock option,  stock  purchase,  stock loan or other benefit plans for
its  directors,   officers  or  employees  or  any  of  the  Company's  dividend
reinvestment  plans,  in each case as now existing or hereafter  established  or
amended)  if at such time (1) there shall have  occurred  any event of which the
Company  has actual  knowledge  that (a) is, or with the giving of notice or the
lapse of time,  or both,  would  be, a  Debenture  Event of  Default  and (b) in
respect of which the Company shall not have taken  reasonable steps to cure, (2)
if such Junior Subordinated  Debentures are held by the Trust, the Company shall
be in default with respect to its payment of any obligations under the Guarantee
or (3) the  Company  shall have given  notice of its  election  of an  Extension
Period,  or any  extension  thereof,  as provided in the Indenture and shall not
have rescinded such notice, and such Extension Period, or any extension thereof,
shall have commenced.

For so long as such  Trust  Securities  remain  outstanding,  the  Company  will
covenant (i) to directly or  indirectly  maintain  100 percent  ownership of the
Common  Securities of such Markel Capital  Trust;  provided,  however,  that any
permitted  successor  of the  Company  under the  Indenture  may  succeed to the
Company's  ownership  of such  Common  Securities,  (ii)  to use its  reasonable
efforts to cause such Trust (a) to remain a statutory business trust,  except in
connection  with the  distribution  of  Junior  Subordinated  Debentures  to the
holders of Trust  Securities in liquidation of such Trust, the redemption of all
of the Trust  Securities of such Trust, or certain  mergers,  consolidations  or
amalgamations,  each as permitted by the  Declaration of such Trust,  and (b) to
continue not to be classified as an  association  taxable as a corporation  or a
partnership  for United States  federal income tax purposes and (iii) to use its
reasonable  efforts to cause each  holder of Trust  Securities  to be treated as
owning an undivided beneficial interest in the Junior Subordinated Debentures.

Debenture Events of Default

The Indenture  provides that any one or more of the following  described  events
with  respect to the Junior  Subordinated  Debentures  constitutes  a "Debenture
Event of Default"  (whatever the reason for such Debenture  Event of Default and
whether it shall be voluntary or  involuntary or be effected by operation of law
or pursuant to


<PAGE>


any judgment,  decree or order of any court or any order,  rule or regulation of
any administrative or governmental body):


        (i)  failure  for 30  days  to pay  any  interest  on  the  Junior
        Subordinated Debentures or any Other Debentures, when due (subject to
        the deferral of any due date in the case of an Extension Period); or


        (ii) failure to pay any principal or premium, if any, on the Junior
        Subordinated Debentures  or  any  Other  Debentures  when  due  whether
        at  maturity,   upon redemption, by declaration of acceleration of
        maturity or otherwise; or


        (iii)  failure  to observe or perform  in any  material  respect
        certain  other covenants  contained in the Indenture  for 90 days after
        written  notice to the Company from the  Debenture  Trustee or the
        holders of at least 25% in aggregate outstanding principal amount of
        Junior Subordinated Debentures; or


        (iv) certain events in bankruptcy, insolvency or reorganization of the
        Company.


The  holders of a majority  in  aggregate  outstanding  principal  amount of the
Junior  Subordinated  Debentures  have the right to direct the time,  method and
place of conducting  any  proceeding  for any remedy  available to the Debenture
Trustee.  The Debenture Trustee or the holders of not less than 25% in aggregate
outstanding  principal amount of the Junior Subordinated  Debentures may declare
the principal due and payable immediately upon a Debenture Event of Default. The
holders of a majority in aggregate  outstanding  principal  amount of the Junior
Subordinated  Debentures may annul such declaration and waive the default if the
default (other than the  nonpayment of the principal of the Junior  Subordinated
Debentures which has become due solely by such  acceleration) has been cured and
a sum sufficient to pay all matured  installments  of interest and principal due
otherwise than by acceleration has been deposited with the Debenture Trustee.

The  holders of a majority  in  aggregate  outstanding  principal  amount of the
Junior Subordinated Debentures affected thereby may, on behalf of the holders of
all the Junior Subordinated Debentures,  waive any past default except a default
in the payment of principal of or premium,  if any, on or interest  (unless such
default has been cured and a sum sufficient to pay all matured  installments  of
interest and premium,  if any, and principal due otherwise than by  acceleration
has been  deposited  with the  Debenture  Trustee)  or a default in respect of a
covenant or provision  which under the  Indenture  cannot be modified or amended
without  the  consent  of the  holder of each  outstanding  Junior  Subordinated
Debenture.

The  Indenture  requires  the annual  filing by the Company  with the  Debenture
Trustee  of a  certificate  as to the  absence  of  certain  defaults  under the
Indenture.

The  Indenture  provides that the  Debenture  Trustee may withhold  notice of an
Indenture  Event of Default from the holders of a series of Junior  Subordinated
Debentures  (except an Indenture Event of Default in payment of principal of, or
of interest or premium on, the Junior Subordinated  Debentures) if the Debenture
Trustee considers it in the interest of such holders to do so.

Enforcement of Certain Rights by Holders of Capital Securities

If a Debenture  Event of Default shall have occurred and be continuing and shall
be attributable to the failure of the Company to pay principal of or interest or
premium, if any, on the Junior Subordinated Debentures on the due date, a holder
of Capital  Securities may institute a Direct Action.  The Company may not amend
the Indenture to remove the foregoing right to bring a Direct Action without the
prior  written  consent  of  the  holders  of all  of  the  Capital  Securities.
Notwithstanding  any  payments  made to a holder of  Capital  Securities  by the
Company in connection with a Direct Action,  the Company shall remain  obligated
to pay  the  principal  of (or  premium,  if  any)  or  interest  on the  Junior
Subordinated  Debentures,  and the Company  shall be subrogated to the rights of
the holder of such  Capital  Securities  with respect to payments on the Capital
Securities  to the extent of any payments  made by the Company to such holder in
any Direct Action.

The holders of the Capital  Securities will not be able to exercise directly any
remedies,  other than those set forth in the preceding  paragraph,  available to
the holders of the Junior  Subordinated  Debentures unless there shall have been
an Event of Default under the Declaration. See "Description of New Securities --
Events of Default; Notice".

Consolidation, Merger, Sale of Assets and Other Transactions

The Indenture provides that the Company shall not consolidate with or merge into
any other Person or convey,  transfer or lease its  properties  and assets as an
entirety or  substantially  as an entirety  to any Person,  and no Person  shall
consolidate  with or merge into the  Company or  convey,  transfer  or lease its
properties  and assets as an  entirety  or  substantially  as an entirety to the
Company,  unless:  (i) in case the  Company  consolidates  with or  merges  into
another Person or conveys or transfers its  properties and assets  substantially
as an entirety to any Person,  the successor  Person is organized under the laws
of the  United  States  or any  State  or the  District  of  Columbia,  and such
successor  Person  expressly  assumes the  Company's  obligations  on the Junior
Subordinated  Debentures;  (ii)  immediately  after giving  effect  thereto,  no
Debenture Event of Default, and no event which, after notice or lapse of time or
both,  would  become a Debenture  Event of Default,  shall have  occurred and be
continuing;  and (iii) certain  other  conditions as prescribed in the Indenture
are met.

The general  provisions  of the  Indenture  do not afford  holders of the Junior
Subordinated  Debentures  protection in the event of a highly leveraged or other
transaction  involving  the Company  that may  adversely  affect  holders of the
Junior Subordinated Debentures.

Modification of the Indenture

From time to time the  Corporation  and the Debenture  Trustee may,  without the
consent  of the  holders  of Junior  Subordinated  Debentures,  amend,  waive or
supplement the Indenture for specified purposes,  including, among other things,
curing  ambiguities,  defects or inconsistencies  (provided that any such action
does not  materially  adversely  affect the  interest  of the  holders of Junior
Subordinated  Debentures) and qualifying,  or maintaining the  qualification of,
the Indenture under the Trust Indenture Act. The Indenture  contains  provisions
permitting  the  Company  and the  Debenture  Trustee,  with the  consent of the
holders  of  not  less  than a  majority  in  principal  amount  of  the  Junior
Subordinated  Debentures of all series affected by such modification at the time
outstanding, to modify the Indenture or any supplemental indenture or the rights
of the  holders of the Junior  Subordinated  Debentures;  provided  that no such
modification shall (i) extend the fixed maturity of any Security,  or reduce the
principal  amount  thereof  (including in the case of a discounted  Security the
amount payable  thereon in the event of  acceleration  or the amount provable in
bankruptcy) or any redemption premium thereon,  or reduce the rate or extend the
time of payment of interest  thereon,  or make the  principal of, or interest or
premium on, the Junior  Subordinated  Debentures payable in any coin or currency
other than that  provided in the Junior  Subordinated  Debentures,  or impair or
affect the right of any holder of Junior  Subordinated  Debentures  to institute
suit for the payment  thereof or the right of prepayment,  if any, at the option
of the holder,  without the consent of the holder of each  Security so affected,
or (ii) reduce the aforesaid  percentage of Junior  Subordinated  Debentures the
consent of the holders of which is required  for any such  modification  without
the consent of the holders of each Security affected.

Satisfaction and Discharge

The Indenture  generally provides that when all Junior  Subordinated  Debentures
not  previously  delivered to the Debenture  Trustee for  cancellation  (i) have
become due and payable or (ii) will  become due and  payable at maturity  within
one year, and the Company  deposits or causes to be deposited with the Debenture
Trustee funds, in trust, for the purpose and in an amount  sufficient to pay and
discharge the entire  indebtedness  on the Junior  Subordinated  Debentures  not
previously  delivered  to  the  Debenture  Trustee  for  cancellation,  for  the
principal  and  interest  to the date of the  deposit or to the Stated  Maturity
Date, as the case may be, then the Indenture  will cease to be of further effect
(except as to the  Company's  obligations  to pay all other sums due pursuant to
the Indenture and to provide the officers'  certificates and opinions of counsel
described  therein),  and the  Company  will be  deemed  to have  satisfied  and
discharged the Indenture.

Subordination

In the  Indenture,  the  Company  has  covenanted  and  agreed  that any  Junior
Subordinated  Debentures  issued  thereunder  will be subordinate  and junior in
right of payment  to all  Senior  Indebtedness  to the  extent  provided  in the
Indenture.  Upon any payment or  distribution  of assets to  creditors  upon any
liquidation, dissolution, winding up, reorganization, assignment for the benefit
of creditors, marshaling of assets or any bankruptcy, insolvency,


<PAGE>


debt  restructuring or similar  proceedings in connection with any insolvency or
bankruptcy  proceeding of the Company,  the holders of Senior  Indebtedness will
first  be  entitled  to  receive  payment  in full  in  respect  of such  Senior
Indebtedness  before  the  holders  of Junior  Subordinated  Debentures  will be
entitled to receive or retain any payment in respect thereof.

In the  event  of  the  acceleration  of the  maturity  of  Junior  Subordinated
Debentures,  the holders of all Senior  Indebtedness  outstanding at the time of
such  acceleration  will first be entitled to receive payment in full in respect
of such Senior Indebtedness before the holders of Junior Subordinated Debentures
will be  entitled  to  receive  or retain  any  payment in respect of the Junior
Subordinated Debentures.

No payments on account of principal or premium, if any, or interest,  if any, in
respect of the Junior  Subordinated  Debentures  may be made if there shall have
occurred  and be  continuing  a default in any  payment  with  respect to Senior
Indebtedness,  or an event of default  with  respect to any Senior  Indebtedness
resulting  in the  acceleration  of the  maturity  thereof,  or if any  judicial
proceeding shall be pending with respect to any such default.

"Senior  Indebtedness"  means, with respect to the Company and its Subsidiaries:
(a) all liabilities, obligations and indebtedness for borrowed money, whether or
not evidenced by bonds, debentures,  notes or other similar instruments, (b) all
obligations to pay the deferred  purchase  price of property or services  (other
than trade payables due and arising in the ordinary course of business), (c) all
Capital Lease Obligations, (d) all debt of any other Person secured by a Lien on
any  asset  of  the  Company  or any of its  Subsidiaries,  (e)  all  Contingent
Obligations, (f) all obligations,  contingent or otherwise, relating to the face
amount of letters of credit, whether or not drawn, and banker's acceptances, but
excluding any obligation  relating to an undrawn letter of credit if the undrawn
letter of credit is issued in  connection  with a liability  for which a reserve
has been  established by the Company or the applicable  Subsidiary in accordance
with  United  States  generally  accepted  accounting  principles,  and  (g) all
obligations  incurred pursuant to Hedging  Agreements which are due and payable;
provided,  that the term  Senior  Indebtedness  shall  not  include  the  Junior
Subordinated Debentures, the Guarantees or other Qualified Debt Obligations.

"Qualified Debt Obligations" means, without duplication,  (a) debt securities of
the Company,  provided  that the terms of any such debt  security (i) permit the
deferral of  principal  and  interest  payments for a period of up to five years
(but not beyond the  maturity  date),  as  elected by the  Company,  (ii) have a
maturity for payment of principal of not less than ten (10) years after the date
of issuance,  and (iii) include  provisions  making the debt security  expressly
subordinate to all other debt of the Company; (b) preferred securities issued by
a Subsidiary,  the sole purpose of which is to issue such  preferred  securities
and invest the  proceeds  thereof in debt  securities  of the type  described in
clause (a) above,  and which preferred  securities are payable solely out of the
proceeds of payments on account of such debt securities; and (c) the obligations
recorded on the  consolidated  balance sheet of the Company and its Subsidiaries
with respect to debt  securities  of the type  described in clause (a) above and
preferred securities of the type described in clause (b) above.

By reason of such subordination, in the event of an insolvency, creditors of the
Company  who are  holders of Senior  Indebtedness,  as well as  certain  general
creditors of the Company,  may recover  more,  ratably,  than the holders of the
Junior  Subordinated  Debentures.  Additionally,  the Company currently conducts
substantially  all of its operations  through  subsidiaries,  and the holders of
Junior  Subordinated  Debentures  will  be  structurally   subordinated  to  the
creditors  of the  Company's  subsidiaries.  See "Risk  Factors  --  Ranking  of
Subordinate   Obligations  Under  the  Guarantee  and  the  Junior  Subordinated
Debentures."

The  Indenture  places no  limitation  on the  amount of  additional  secured or
unsecured debt, including Senior Indebtedness, or other obligations, that may be
incurred  by the  Company.  The  Company  expects  from  time to  time to  incur
additional indebtedness and obligations, including Senior Indebtedness.

Governing Law

The Indenture  and the Junior  Subordinated  Debentures  will be governed by and
construed in accordance with the laws of the State of New York.

Information Concerning the Debenture Trustee

Following the Exchange Offer and the  qualification  of the Indenture  under the
Trust Indenture Act, the Debenture  Trustee shall have and be subject to all the
duties and responsibilities specified with respect to an indenture trustee under
the Trust Indenture Act.  Subject to such provisions,  the Debenture  Trustee is
under no  obligation to exercise any of the powers vested in it by the Indenture
at the request of any holder of Junior Subordinated  Debentures,  unless offered
reasonable indemnity by such holder against the costs,  expenses and liabilities
which might be incurred thereby. The Debenture Trustee is not required to expend
or risk its own funds or otherwise  incur  personal  financial  liability in the
performance  of its duties if the  Debenture  Trustee  reasonably  believes that
repayment or adequate indemnity is not reasonably assured to it.

From time to time, the Debenture Trustee and/or its affiliates extend credit and
may provide investment banking and other financial services to the Company. See
"Markel Capital Trust I."


                          DESCRIPTION OF THE GUARANTEE

The Old Guarantee was executed and  delivered by the Company  concurrently  with
the issuance by the Trust of the Old Capital  Securities  for the benefit of the
holders from time to time of the Old Capital Securities.  As soon as practicable
after the date hereof,  the Old  Guarantee  will be exchanged by the Company for
the New  Guarantee  for the benefit of the holders  from time to time of the New
Capital  Securities.  The Chase  Manhattan  Bank will act as  guarantee  trustee
("Guarantee Trustee") under the Guarantee.  The New Guarantee has been qualified
under the Trust  Indenture  Act.  This  summary  of  certain  provisions  of the
Guarantee  does not purport to be complete  and is subject to, and  qualified in
its entirety by reference to, all of the provisions of the Guarantee,  including
the  definitions  therein of certain  terms,  and the Trust  Indenture  Act. The
Guarantee  Trustee will hold the Guarantee for the benefit of the holders of the
Capital Securities.

General

The Company will  irrevocably  agree to pay in full on a subordinated  basis, to
the extent set forth herein,  the Guarantee  Payments (as defined  below) to the
holders  of the New  Capital  Securities,  as and when  due,  regardless  of any
defense,  right of  set-off  or  counterclaim  that the Trust may have or assert
other than the defense of payment.  The  following  payments with respect to the
Capital  Securities,  to the  extent  not paid by or on behalf of the Trust (the
"Guarantee Payments"), will be subject to the Guarantee: (i) any accumulated and
unpaid  Distributions  required  to be paid on New  Capital  Securities,  to the
extent the Trust has funds on hand at such time legally available therefor, (ii)
the  Redemption  Price with  respect to any New  Capital  Securities  called for
redemption,  to the extent that the Trust has funds on hand at such time legally
available  therefor,  or (iii) upon a voluntary or involuntary  termination  and
liquidation  of  the  Trust  (unless  the  Junior  Subordinated  Debentures  are
distributed  to  holders  of the  Capital  Securities),  the  lesser  of (a) the
Liquidation  Distribution  and (b) the  amount of assets of the Trust  remaining
available for distribution to holders of New Capital  Securities.  The Company's
obligation to make a Guarantee Payment may be satisfied by direct payment of the
required amounts by the Company to the holders of the New Capital  Securities or
by causing the Trust to pay such amounts to such holders.

The New Guarantee  will rank  subordinate  and junior in right of payment to all
Senior  Indebtedness  to the  extent  provided  therein  and,  in the  event  of
bankruptcy  or  insolvency   proceedings   involving  the  Company,   will  rank
subordinate and junior in right of payment to all liabilities  (other than Other
Guarantees)  of the  Company,  but senior to any  obligations  in respect of any
class of capital  stock of the  Company.  See " -- Status"  below.  Because  the
Company is a holding  company,  the right of the Company to  participate  in any
distribution of assets of any subsidiary upon such  subsidiary's  liquidation or
reorganization  or otherwise is subject to the prior claims of creditors of that
subsidiary,  except to the extent the  Company  may  itself be  recognized  as a
creditor of that subsidiary.  Accordingly,  the Company's  obligations under the
Guarantee  will  be  effectively   subordinated   to  all  existing  and  future
liabilities  of the Company's  direct and indirect  subsidiaries,  and claimants
should  look only to the assets of the  Company  for  payments  thereunder.  See
"Description  of  New  Junior  Subordinated  Debentures  --  General."  The  New
Guarantee  does not  limit  the  incurrence  or  issuance  of other  secured  or
unsecured debt of the Company, including Senior Indebtedness,  whether under the
Indenture,  any other indenture that the Company may enter into in the future or
otherwise.

The  Company  will,   through  the  Guarantee,   the  Declaration,   the  Junior
Subordinated Debentures and the Indenture,  taken together,  fully,  irrevocably
and unconditionally guarantee all of the Trust's obligations under the Capital
Securities. No single document standing alone or operating in conjunction with
fewer than all of the other documents constitutes such guarantee. It is only the
combined operation of these documents that has the effect of providing a full,
irrevocable and unconditional guarantee of the Trust's obligations under the
Capital Securities. See "Relationship Among the New Capital Securities, the New
Junior Subordinated Debentures and the New Guarantee."

Status

The New Guarantee  will  constitute  an unsecured  obligation of the Company and
will rank subordinate and junior in right of payment to all Senior  Indebtedness
in the same  manner as Junior  Subordinated  Debentures,  except in the event of
bankruptcy or insolvency  proceedings  involving the Company,  in which case the
New  Guarantee  will rank  subordinate  and  junior in right of  payment  to all
liabilities (other than Other Guarantees) of the Company.


<PAGE>


The New  Guarantee  will rank pari  passu with the Old  Guarantee  and all Other
Guarantees  issued by the Company.  The Guarantee will constitute a guarantee of
payment and not of collection  (i.e., the guaranteed party may institute a legal
proceeding  directly  against  the  Company  to  enforce  its  rights  under the
Guarantee without first instituting a legal proceeding  against any other person
or  entity).  The  Guarantee  will be held for the benefit of the holders of the
Capital  Securities.  The Guarantee will not be discharged  except by payment of
the  Guarantee  Payments  in full to the  extent  not paid by the  Trust or upon
distribution to the holders of the Capital Securities of the Junior Subordinated
Debentures.  The  Guarantee  does  not  place  a  limitation  on the  amount  of
additional Senior Indebtedness that may be incurred by the Company.  The Company
expects from time to time to incur additional  indebtedness  constituting Senior
Indebtedness.

Amendments and Assignment

Except with respect to any changes that do not materially  adversely  affect the
rights of  holders  of the  Capital  Securities  (in which  case no vote will be
required),  the Guarantee may not be amended  without the prior  approval of the
holders of a majority  of the  Liquidation  Amount of such  outstanding  Capital
Securities. The manner of obtaining any such approval will be as set forth under
"Description of New Securities -- Voting Rights;  Amendment of the Declaration."
All guarantees and agreements  contained in the Guarantee  Agreement  shall bind
the successors,  assigns, receivers, trustees and representatives of the Company
and shall inure to the benefit of the  holders of the  Capital  Securities  then
outstanding.

Events of Default

An event of default  under the  Guarantee  will  occur  upon the  failure of the
Company  to perform  any of its  payment or other  obligations  thereunder.  The
holders of a majority in Liquidation  Amount of the Capital Securities will have
the right to direct the time,  method and place of conducting any proceeding for
any remedy available to the Guarantee  Trustee in respect of the Guarantee or to
direct the exercise of any trust or power  conferred upon the Guarantee  Trustee
under the Guarantee.

Any holder of the Capital  Securities may institute a legal proceeding  directly
against the  Company to enforce its rights  under the  Guarantee  without  first
instituting a legal proceeding  against the Trust, the Guarantee  Trustee or any
other person or entity.

The Company, as guarantor,  will be required to file annually with the Guarantee
Trustee a certificate as to whether or not the Company is in compliance with all
the conditions and covenants applicable to it under the Guarantee.

Certain Covenants of the Company

In the New  Guarantee  the Company will  covenant  that,  so long as any Capital
Securities  remain  outstanding,  the  Company  shall not (i) declare or pay any
dividends  or  distributions  on,  or  redeem,  purchase,  acquire,  or  make  a
liquidation  payment with respect to, any of the Company's  capital stock (which
includes  common and  preferred  stock) or (ii) make any  payment of  principal,
interest  or  premium,  if any,  on, or repay or  repurchase  or redeem any debt
securities of the Company  (including any Other Debentures) that rank pari passu
with or junior in right of  payment  to the Junior  Subordinated  Debentures  or
(iii) make any  guarantee  payments with respect to any guarantee by the Company
of the  debt  securities  of any  subsidiary  of the  Company  (including  Other
Guarantees) if such guarantee  ranks pari passu or junior in right of payment to
the Junior Subordinated Debentures (other than (a) dividends or distributions in
shares of, or options,  warrants, rights to subscribe for or purchase shares of,
common stock of the Company,  (b) any  declaration  of a dividend in  connection
with the  implementation  of a  stockholder's  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 Guarantee,  (d) as a result
of a  reclassification  of the  Company's  capital  stock or the exchange or the
conversion  of one class or series of the  Company's  capital  stock for another
class or series of the Company's  capital stock,  (e) the purchase of fractional
interests in shares of the Company's capital stock pursuant to the conversion or
exchange  provisions  of such capital stock or the security  being  converted or
exchanged, and (f) purchases or issuances of common stock in connection with any
of the Company's stock option, stock purchase, stock loan or other benefit plans
for its  directors,  officers  or  employees  or any of the  Company's  dividend
reinvestment plans, in each case as now existing or hereafter established or


<PAGE>


amended),  if at such time (i) there shall have  occurred any event of which the
Company  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 under the Guarantee and (b)
in respect of which the Company shall not have taken  reasonable  steps to cure,
(ii) if such Junior  Subordinated  Debentures are held by the Property  Trustee,
the Company  shall be in default with respect to its payment of any  obligations
under the Guarantee or (iii) the Company shall have given notice of its election
of the exercise of its right to extend the interest  payment period  pursuant to
the Indenture and any such extension shall be continuing.

Termination

The  Guarantee  will  terminate  and be of no further force and effect upon full
payment of the applicable Redemption Price of the Capital Securities,  upon full
payment of the Liquidation  Amount payable upon liquidation of the Trust or upon
distribution  of Junior  Subordinated  Debentures  to the holders of the Capital
Securities.  The Guarantee  will continue to be effective or will be reinstated,
as the case may be, if at any time any  holder of the  Capital  Securities  must
restore payment of any sums paid under the Capital Securities or the Guarantee.

Information Concerning the Guarantee Trustee

The  Guarantee  Trustee,  other than during the  continuance  of a default  with
respect  to a  Guarantee,  will  undertake  to perform  only such  duties as are
specifically  set forth in such Guarantee and, after default,  must exercise the
same degree of care as a prudent individual would exercise in the conduct of his
or her own affairs.  Subject to such provisions,  the Guarantee Trustee is under
no obligation to exercise any of the powers vested in it by the Guarantee at the
request of any holder of Capital Securities, unless offered reasonable indemnity
against the costs, expenses and liabilities which might be incurred thereby. The
Guarantee  Trustee is not  required to expend or risk its own funds or otherwise
incur  personal  financial  liability  in the  performance  of its  duties if it
reasonably  believes  that  repayment or adequate  indemnity  is not  reasonably
assured to it.

From time to time the Guarantee Trustee and/or its affiliates extend credit and
may provide investment banking and other financial services to the Company. See
"Markel Capital Trust I."

Governing Law

The  Guarantee  will be governed  by, and  construed  in  accordance  with,  the
internal laws of the State of New York.

                         DESCRIPTION OF OLD SECURITIES

       The terms of the Old Securities  are identical in all materials  respects
to the New  Securities,  except that the Old Securities have not been registered
under the Securities  Act, are subject to certain  restrictions  on transfer and
are  entitled  to  certain  rights  under  the  applicable  Registration  Rights
Agreement (which rights will terminate upon  consummation of the Exchange Offer,
except under limited circumstances), the New Capital Securities will not contain
the $100,000 minimum  Liquidation Amount transfer  restriction and certain other
restrictions on transfer applicable to Old Capital  Securities,  the New Capital
Securities will not provide for any increase in the  Distribution  rate thereon,
the New Junior  Subordinated  Debentures  will not contain the $100,000  minimum
principal amount transfer restriction and the New Junior Subordinated Debentures
will  not  provide  for any  increase  in the  interest  rate  thereon.  The Old
Securities provide that, in the event that a registration  statement relating to
the  Exchange  Offer  has not  been  filed by June 7,  1997  and  been  declared
effective by July 7, 1997, or, in certain limited circumstances,  in the event a
shelf registration  statement (the "Shelf Registration  Statement") with respect
to the resale of the Old Capital Securities is not declared effective by July 7,
1997,  then interest will accrue (in addition to the stated interest rate on the
Old  Junior  Subordinated  Debentures)  at the  rate of 0.25%  per  annum on the
principal  amount of the Old Junior  Subordinated  Debentures and  Distributions
will  accrue (in  addition  to the stated  Distribution  rate on the Old Capital
Securities) at the rate of 0.25% per annum on the Liquidation  Amount of the Old
Capital Securities,  for the period from the occurrence of such event until such
time as such  required  Exchange  Offer is  consummated  or any  required  Shelf
Registration  Statement  is  effective.  The New  Securities  are not,  and upon
consummation  of the Exchange Offer the Old Securities  will not be, entitled to
any such  additional  interest  or  Distributions.  Accordingly,  holders of Old
Capital   Securities  should  review  the  information  set  forth  under  "Risk
Factors--Consequences  of a Failure to  Exchange  Old  Capital  Securities"  and
"Description of New Securities."

               RELATIONSHIP AMONG THE NEW CAPITAL SECURITIES, THE
            NEW JUNIOR SUBORDINATED DEBENTURES AND THE NEW GUARANTEE

Full and Unconditional Guarantee

Payments of  Distributions  and other amounts due on the New Capital  Securities
(to the extent the Trust has funds on hand legally  available for the payment of
such Distributions) will be irrevocably  guaranteed by the Company as and to the
extent set forth under  "Description  of the  Guarantee."  Taken  together,  the
Company's  obligations  under  the  New  Junior  Subordinated  Debentures,   the
Indenture, the Declaration and the New Guarantee will provide, in the aggregate,
a full,  irrevocable  and  unconditional  guarantee  of  payments of
Distributions  and other  amounts due on the New Capital  Securities.  No single
document  standing alone or operating in conjunction  with fewer than all of the
other documents constitutes such guarantee. It is only the combined operation of
these  documents  that has the  effect  of  providing  a full,  irrevocable  and
unconditional  guarantee  of the  Trust's  obligations  under  the  New  Capital
Securities.  If and to the extent


<PAGE>


that the Company  does not make the  required payments  on the New  Junior
Subordinated  Debentures,  the Trust will not have sufficient funds to make the
related payments,  including Distributions,  on the New Capital  Securities. The
Guarantee will not cover any such payment when the Trust does not have
sufficient funds on hand legally available therefor. In such event,  the remedy
of a holder of Capital  Securities  is to  institute a Direct Action.  The
obligations  of the  Company  under  the  New  Guarantee  will  be subordinate
and junior in right of payment to all Senior Indebtedness.

Sufficiency of Payments

As long as  payments  of interest  and other  payments  are made when due on the
Junior  Subordinated  Debentures,  such  payments  will be  sufficient  to cover
Distributions  and other payments due on the New Capital  Securities,  primarily
because:  (i) the  aggregate  principal  amount or  Prepayment  Price of the New
Junior  Subordinated  Debentures  will be  equal  to the sum of the  Liquidation
Amount or Redemption  Price,  as applicable,  of the New Capital  Securities and
Common  Securities;  (ii) the interest rate and interest and other payment dates
on the New Junior  Subordinated  Debentures will match the Distribution rate and
Distribution and other payment dates for the Trust Securities; (iii) the Company
shall pay for all and any costs,  expenses and  liabilities  of the Trust except
the  Trust's  obligations  to  holders  of Trust  Securities  under  such  Trust
Securities;  and  (iv)  the  Declaration  will  provide  that  the  Trust is not
authorized  to engage in any activity  that is not  consistent  with the limited
purposes thereof.

Enforcement of Rights of Holders of Capital Securities

A holder of any  Capital  Security  may  institute a legal  proceeding  directly
against the  Company to enforce its rights  under the  Guarantee  without  first
instituting a legal proceeding against the Guarantee  Trustee,  the Trust or any
other person or entity.

A default or event of default under any Senior Indebtedness would not constitute
a default or Event of Default under the  Declaration.  However,  in the event of
payment   defaults  under,  or  acceleration   of,  Senior   Indebtedness,   the
subordination  provisions of the Indenture  will provide that no payments may be
made  in  respect  of the  Junior  Subordinated  Debentures  until  such  Senior
Indebtedness  has been paid in full or any payment  default  thereunder has been
cured or  waived.  Failure  to make  required  payments  on Junior  Subordinated
Debentures would constitute an Event of Default under the Declaration.

Limited Purpose of the Trust

The Capital  Securities  will represent  preferred  beneficial  interests in the
Trust,  and the Trust  exists for the sole  purpose of issuing  and  selling the
Trust  Securities,  using the proceeds from the sale of the Trust  Securities to
acquire  the Junior  Subordinated  Debentures  and  engaging in only those other
activities  necessary,  advisable or incidental thereto. A principal  difference
between  the rights of a holder of a Capital  Security  and a holder of a Junior
Subordinated  Debenture is that a holder of a Junior Subordinated Debenture will
be entitled to receive from the Company the principal amount of and premium,  if
any,  and interest on Junior  Subordinated  Debentures  held,  while a holder of
Capital  Securities is entitled to receive  Distributions from the Trust (or, in
certain  circumstances,  from the  Company  under the  Guarantee)  if and to the
extent the Trust has funds on hand  legally  available  for the  payment of such
Distributions.

Rights Upon Termination

Unless the Junior  Subordinated  Debentures  are  distributed  to holders of the
Trust Securities,  upon any voluntary or involuntary termination and liquidation
of the Trust,  the holders of the Trust  Securities will be entitled to receive,
out of assets  held by the Trust,  the  Liquidation  Distribution  in cash.  See
"Description  of  Securities --  Liquidation  of the Trust and  Distribution  of
Junior Subordinated  Debentures." Upon any voluntary or involuntary  liquidation
or  bankruptcy  of the Company,  the Property  Trustee,  as holder of the Junior
Subordinated  Debentures,  would  be a  subordinated  creditor  of the  Company,
subordinated in right of payment to all Senior  Indebtedness as set forth in the
Indenture, but entitled to receive payment in full of principal (and premium, if
any) and interest,  before any  stockholders of the Company receive  payments or
distributions.  Since the Company will be the guarantor  under the Guarantee and
will agree to pay for all costs,  expenses and  liabilities  of the Trust (other
than the  Trust's  obligations  to the  holders  of its Trust  Securities),  the
positions of a holder of Capital Securities and a holder of Junior  Subordinated
Debentures relative to other creditors and to stockholders of the Company in the
event of  liquidation  or  bankruptcy of the Company are expected to be similar,
although,  in the event of bankruptcy or  insolvency  proceedings  involving the
Company, the Company's obligations under the Guarantee will rank subordinate and
junior in right of payment to all liabilities  (other than Other  Guarantees) of
the  Company  but senior to any  obligations  in respect of any class of capital
stock of the Company.

                    CERTAIN FEDERAL INCOME TAX CONSEQUENCES

General

In the  opinion  of  McGuire,  Woods,  Battle & Boothe,  L.L.P.,  counsel to the
Company and the Trust ("Tax Counsel"),  the following is a summary of certain of
the material  United States  federal  income tax  consequences  of the purchase,
ownership and  disposition  of Capital  Securities  held as capital  assets by a
holder that purchased the Old Capital  Securities upon initial issuance at their
original  offering  price. It does not deal with special classes of holders such
as  banks,  thrifts,   real  estate  investment  trusts,   regulated  investment
companies, insurance companies, dealers in securities or currencies,  tax-exempt
investors,  or persons that will hold the Capital  Securities as a position in a
"straddle,"  as  part  of a  "synthetic  security"  or  "hedge,"  as  part  of a
"conversion  transaction"  or other  integrated  investment,  or as other than a
capital  asset.  This  summary  also does not  address the tax  consequences  to
persons that have a functional  currency  other than the U.S.  dollar or the tax
consequences to  shareholders,  partners or beneficiaries of a holder of Capital
Securities.  Further,  it does not include any  description  of any  alternative
minimum tax  consequences or the tax laws of any state or local government or of
any foreign  government that may be applicable to the Capital  Securities.  This
summary is based on the Internal  Revenue Code of 1986, as amended (the "Code"),
Treasury regulations thereunder, the administrative and judicial interpretations
thereof, as of the date hereof, all of which are subject to change,  possibly on
a retroactive basis.

Exchange of Capital Securities

The exchange of Old Capital  Securities for New Capital Securities should not be
a taxable event to holders for United States  federal  income tax purposes.  The
exchange of Old Capital  Securities for New Capital  Securities  pursuant to the
Exchange  Offer should not be treated as an "exchange" for United States federal
income tax purposes because the New Capital  Securities should not be considered
to differ  materially  in kind or extent  from the Old  Capital  Securities  and
because the  exchange  will occur by  operation  of the terms of the Old Capital
Securities.  If, however, the exchange of the Old Capital Securities for the New
Capital  Securities were treated as an exchange for United States federal income
tax purposes,  such exchange should  constitute a  recapitalization  for federal
income tax purposes.  Accordingly,  the New Capital  Securities  should have the
same issue price as the Old  Capital  Securities,  and a holder  should have the
same adjusted tax basis and holding period in the New Capital  Securities as the
holder had in the Old Capital Securities immediately before the exchange.

Classification of the Junior Subordinated Debentures

In connection with the issuance of the Old Junior Subordinated  Debentures,  Tax
Counsel  has  rendered  its opinion  generally  to the effect  that,  under then
current law and assuming full  compliance  with the terms of the Indenture  (and
certain other documents),  and based on certain facts and assumptions  contained
in such opinion,  the Junior  Subordinated  Debentures  will be  classified  for
United States federal  income tax purposes as  indebtedness  of the Company.  An
opinion of Tax Counsel,  however, is not binding on the Internal Revenue Service
(the "IRS") or the  courts.  Prospective  investors  should note that no rulings
have been or are expected to be sought from the IRS with respect to any of these
issues  and no  assurance  can be given  that  the IRS  will  not take  contrary
positions.  Moreover,  no  assurance  can be  given  that  any  of the  opinions
expressed herein will not be challenged by the IRS or, if challenged,  that such
a challenge would not be successful.

Classification of the Trust

In connection with the issuance of the Old Capital  Securities,  Tax Counsel has
rendered its opinion  generally  to the effect that,  under then current law and
assuming full  compliance  with the terms of the  Declaration  and the Indenture
(and  certain  other  documents),  and based on  certain  facts and  assumptions
contained  in such  opinion,  the Trust will be  classified  for  United  States
federal income tax purposes as a grantor trust and not as an association taxable
as a  corporation.  Accordingly,  for United States federal income tax purposes,
each holder of Capital  Securities  generally will be considered the owner of an
undivided interest in the Junior Subordinated  Debentures,  and each holder will
be required to include in its gross income any  interest  (or OID accrued)  with
respect to its allocable share of those Junior Subordinated Debentures.

Interest Income and Original Issue Discount

Under recently issued Treasury  regulations  (the  "Regulations")  applicable to
debt instruments issued on or after August 13, 1996, a "remote" contingency that
stated interest will not be timely paid will be ignored in determining whether a
debt instrument is issued with OID. The Company  believes that the likelihood of
its  exercising  its option to defer  payments of  interest is "remote"  because
exercising that option would prevent the Company from declaring dividends on any
class of its equity  securities.  Accordingly,  the Company  intends to take the
position,  based on the  advice of Tax  Counsel,  that the  Junior  Subordinated
Debentures will not be considered to be issued with OID and, accordingly, stated
interest on the Junior  Subordinated  Debentures  generally will be taxable to a
holder as ordinary  income at the time it is paid or accrued in accordance  with
such holder's method of accounting.


<PAGE>


Under the  Regulations,  if the  Company  were to  exercise  its option to defer
payments of interest, the New Junior Subordinated  Debentures would at that time
be  treated  as issued  with OID,  and all  stated  interest  on the New  Junior
Subordinated  Debentures  would  thereafter be treated as OID as long as the New
Junior  Subordinated  Debentures  remain  outstanding.  In such event,  all of a
holder's  taxable  interest  income with respect to the New Junior  Subordinated
Debentures  would  thereafter  be  accounted  for on an economic  accrual  basis
regardless of such holder's method of tax accounting,  and actual  distributions
of stated  interest  would not be reported as taxable  income.  Consequently,  a
holder of New Capital  Securities  would be required to include in gross  income
OID even  though the  Company  would not make  actual  cash  payments  during an
Extension Period.  Moreover,  under the Regulations,  if the option to defer the
payment of interest was determined not to be "remote",  the Junior  Subordinated
Debentures  would be treated as having been originally  issued with OID. In such
event,  all of a holder's  taxable  interest  income with  respect to the Junior
Subordinated  Debentures  would be accounted  for on an economic  accrual  basis
regardless of such holder's method of tax accounting,  and actual  distributions
of stated interest would not be reported as taxable income.

The   Regulations   have  not  yet  been  addressed  in  any  rulings  or  other
interpretations  by the  IRS,  and it is  possible  that  the IRS  could  take a
position contrary to Tax Counsel's interpretation herein.

Because  income on the  Capital  Securities  will  constitute  interest  or OID,
corporate  holders  of  the  Capital  Securities  will  not  be  entitled  to  a
dividends-received  deduction with respect to any income recognized with respect
to the Capital Securities.

Receipt of Junior Subordinated Debentures or Cash Upon Liquidation of the Trust

The Company will have the right at any time to liquidate the Trust and cause the
New Junior Subordinated Debentures to be distributed to the holders of the Trust
Securities.  Under current law, such a  distribution,  for United States federal
income tax purposes,  would be treated as a nontaxable event to each holder, and
each holder would receive an aggregate tax basis in the New Junior  Subordinated
Debentures equal to such holder's aggregate tax basis in its Capital Securities.
A holder's holding period in the New Junior Subordinated  Debentures so received
in  liquidation  of the Trust would  include the period during which the Capital
Securities were held by such holder. If, however, the Trust is characterized for
United  States  federal  income  tax  purposes  as an  association  taxable as a
corporation at the time of its  dissolution,  the distribution of the New Junior
Subordinated  Debentures  may  constitute a taxable  event to holders of Capital
Securities and a holder's holding period in New Junior  Subordinated  Debentures
would begin on the date such Junior Subordinated Debentures were received.

Under  certain   circumstances   described  herein  (see   "Description  of  New
Securities"),  the Junior  Subordinated  Debentures may be redeemed for cash and
the proceeds of such  redemption  distributed  to holders in redemption of their
Capital  Securities.  Under  current law,  such a redemption  would,  for United
States  federal  income tax purposes,  constitute a taxable  disposition  of the
redeemed Capital Securities,  and a holder could recognize gain or loss as if it
sold  such  redeemed  Capital  Securities  for cash.  See " -- Sales of  Capital
Securities" below.

Sales of Capital Securities

A holder that sells Capital  Securities will recognize gain or loss equal to the
difference  between its  adjusted  tax basis in the Capital  Securities  and the
amount realized on the sale of such Capital  Securities (other than with respect
to accrued and unpaid interest which has not yet been included in income,  which
will be treated  as  ordinary  income).  A  holder's  adjusted  tax basis in the
Capital Securities generally will be its initial purchase price increased by OID
(if any)  previously  includable  in such  holder's  gross income to the date of
disposition  and  decreased  by  payments  (if  any)  received  on  the  Capital
Securities in respect of OID. Such gain or loss generally will be a capital gain
or loss and  generally  will be a long-term  capital gain or loss if the Capital
Securities have been held for more than one year.

The Capital Securities may trade at a price that does not accurately reflect the
value of accrued  but unpaid  interest  with  respect to the  underlying  Junior
Subordinated  Debentures. A holder who uses the accrual method of accounting for
tax purposes (and a cash method holder,  if the Junior  Subordinated  Debentures
are deemed to have been issued with OID) who disposes of such  holder's  Capital
Securities  between record dates for payments of  distributions  thereon will be
required  to include  accrued  but unpaid  interest  on the Junior  Subordinated
Debentures  through the date of disposition in income as ordinary  income (i.e.,
interest or,  possibly,  OID), and to add such amount to such holder's  adjusted
tax basis in such holder's pro rata share of the underlying Junior  Subordinated
Debentures  deemed disposed of. To the extent the selling price is less than the
holder's  adjusted  tax  basis  (which  will  include  all  accrued  but  unpaid
interest),  a holder will recognize a capital loss.  Subject to certain  limited
exceptions,  capital  losses  cannot be  applied to offset  ordinary  income for
United States federal income tax purposes.

Proposed Tax Legislation

On February 6, 1997, as part of the Clinton  Administration's Fiscal 1998 Budget
Proposal,   the  Treasury   Department   proposed   legislation  (the  "Proposed
Legislation") which would, among other things,  generally deny corporate issuers
a deduction for interest in respect of certain debt obligations, such as the New
Junior Subordinated Debentures,  issued on or after the date "of first committee
action," if such debt obligations have a maximum term in excess of 15 years and
are not  shown  as  indebtedness  on the  issuer's  applicable  consolidated
balance  sheet.  In addition,  the Proposed  Legislation  would  generally  deny
corporate   issuers  a  deduction  for  interest  in  respect  of  certain  debt
obligations,  such as the New Junior Subordinated Debentures, issued on or after
the date "of first committee  action," if such debt  obligations have a weighted
average  maturity of more than 40 years.  The Proposed  Legislation  has not yet
been introduced by the 105th Congress. If the Proposed Legislation is enacted by
Congress and if such  enactment  gave rise to a Tax Event,  the Company would be
permitted to cause a redemption  of the Trust  Securities  at the Special  Event
Redemption Price by electing to prepay the Junior Subordinated Debentures at the
Special Event  Prepayment  Price.  See  "Description of New Junior  Subordinated
Debentures -- Special Event Prepayment."

United States Alien Holders

For  purposes  of  this  discussion,  a  "United  States  Alien  Holder"  is any
corporation,  individual, partnership, estate or trust that is not a U.S. Holder
for United States federal income tax purposes.

A "U.S.  Holder" is a holder of Capital  Securities who or which is a citizen or
individual  resident (or is treated as a citizen or individual  resident) of the
United States for federal  income tax purposes,  a  corporation  or  partnership
created or organized (or treated as created or organized for federal  income tax
purposes) in or under the laws of the United States or any political subdivision
thereof,  or a trust or estate  the income of which is  includable  in its gross
income  for  federal   income  tax  purposes   without  regard  to  its  source.
Notwithstanding  the foregoing,  for taxable years  beginning after December 31,
1996 (or for the immediately  preceding  taxable year, if the trustee of a trust
so elects),  a trust is a U.S.  Holder for federal  income tax  purposes if, and
only if,  (i) a court  within  the  United  States is able to  exercise  primary
supervision  over the  administration  of the trust and (ii) one or more  United
States trustees have the authority to control all  substantial  decisions of the
trust.

Under present  United States  federal income tax laws: (i) payments by the Trust
or any of its paying agents to any holder of a Capital  Security who or which is
a United  States  Alien  Holder  will not be  subject to United  States  federal
withholding tax; provided that, (a) the beneficial owner of the Capital Security
does not actually or constructively own 10 percent or more of the total combined
voting  power of all classes of stock of the Company  entitled to vote,  (b) the
beneficial owner of the Capital Security is not a controlled foreign corporation
that is related to the Company through stock  ownership,  and (c) either (A) the
beneficial  owner of the Capital  Security  certifies to the Trust or its agent,
under  penalties of perjury,  that it is not a United States holder and provides
its name and address or (B) a securities  clearing  organization,  bank or other
financial institution that holds customers' securities in the ordinary course of
its trade or  business  (a  "Financial  Institution"),  and  holds  the  Capital
Security in such capacity,  certifies to the Trust or its agent, under penalties
of perjury,  that such statement has been received from the beneficial  owner by
it or by a  Financial  Institution  between  it and  the  beneficial  owner  and
furnishes the Trust or its agent with a copy  thereof;  and (ii) a United States
Alien Holder of a Capital  Security will not be subject to United States federal
withholding  tax on any gain  realized upon the sale or other  disposition  of a
Capital Security.

Information Reporting to Holders

Generally,  income on the New Capital  Securities will be reported to holders on
Form 1099, which forms should be mailed to holders of New Capital  Securities by
January 31 following each calendar year.

Backup Withholding

Payments made on, and proceeds from the sale of, the Capital  Securities  may be
subject to a "backup"  withholding  tax of 31 percent unless the holder complies
with certain identification  requirements.  Any withheld amounts will be allowed
as a credit against the holder's United States federal income tax,  provided the
required information is provided to the IRS.

THE UNITED STATES  FEDERAL INCOME TAX DISCUSSION SET FORTH ABOVE IS INCLUDED FOR
GENERAL  INFORMATION  ONLY AND MAY NOT BE APPLICABLE  DEPENDING  UPON A HOLDER'S
PARTICULAR SITUATION.  HOLDERS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO
THE TAX CONSEQUENCES TO THEM OF THE PURCHASE, OWNERSHIP DISPOSITION AND EXCHANGE
OF THE CAPITAL  SECURITIES,  INCLUDING THE TAX CONSEQUENCES UNDER STATE,  LOCAL,
FOREIGN AND OTHER TAX LAWS AND THE POSSIBLE  EFFECTS OF CHANGES IN UNITED STATES
FEDERAL OR OTHER TAX LAWS.

                              ERISA CONSIDERATIONS

The  Company,  which is the  obligor  with  respect to the  Junior  Subordinated
Debentures held by the Trust, and its affiliates and the Property Trustee may be
considered a "party in interest" (within the meaning of the Employee  Retirement
Income Security Act of 1974, as amended  ("ERISA")) or a  "disqualified  person"
(within the meaning of Section 4975 of the Code) with  respect to many  employee
benefit plans  ("Plans") that are subject to ERISA.  Any purchaser  proposing to
acquire  Capital  Securities  with  assets of any Plan should  consult  with its
counsel.  The purchase  and/or  holding of Capital  Securities by a Plan that is
subject to the fiduciary  responsibility  provisions of ERISA or the  prohibited
transaction  provisions  of  Section  4975  of the  Code  (including  individual
retirement arrangements  and other plans  described in Section  4975(e)(1) of
the Code) and with respect to which the Company,  the Property  Trustee or any
affiliate is a service provider (or otherwise is a party in interest or a
disqualified person)
may constitute or result in a prohibited transaction under ERISA or Section 4975
of the Code,  unless such Capital  Securities  are  acquired  pursuant to and in
accordance with an applicable  exemption,  such as Prohibited  Transaction Class
Exemption ("PTCE") 84-14 (an exemption for certain transactions determined by an
independent qualified professional asset manager),  PTCE 91-38 (an exemption for
certain transactions  involving bank collective investment funds), PTCE 90-1 (an
exemption for certain  transactions  involving insurance company pooled separate
accounts)  or PTCE  95-60  (an  exemption  for  transactions  involving  certain
insurance  company  general  accounts)  and PTCE 95-23 (an exemption for certain
transactions  determined by an in-house manager).  In addition, a Plan fiduciary
considering the purchase of Capital  Securities  should be aware that the assets
of the Trust may be considered  "plan assets" for ERISA purposes.  Therefore,  a
Plan fiduciary should consider whether the purchase of


<PAGE>



Capital  Securities could result in a delegation of fiduciary  authority to the
Property Trustee,  and, if so,  whether such a delegation  of  authority  is
permissible  under the Plan's governing  instrument or any investment management
agreement with the Plan. In making  such  determination,  a Plan  fiduciary
should  note that the  Property Trustee is a U.S. bank qualified to be an
investment manager (within the meaning of section  3(38) of ERISA) to which such
a delegation  of  authority  generally would be  permissible  under ERISA.
Further,  prior to an Event of Default with respect to the Junior  Subordinated
Debentures,  the Property Trustee will have only limited custodial and
ministerial authority with respect to Trust assets.

Under the U.S. Department of Labor regulations  defining "plan assets" for ERISA
purposes  (the  "Plan  Assets  Regulations"),  the  assets  of the  Trust may be
considered  plan  assets of Plans  owning  New  Capital  Securities  unless  the
aggregate  investment in New Capital  Securities by "benefit plan  investors" is
not deemed  "significant"  or the New Capital  Securities  qualify as  "publicly
offered  securities" as defined in such  Regulations.  For this purpose,  equity
participation by benefit plan investors will not be considered  "significant" on
any date only if,  immediately  after the most  recent  acquisition  of  Capital
Securities, the aggregate interest in the New Capital Securities held by benefit
plan investors will be less than 25% of the value of the New Capital Securities.
For purposes of the Plan Asset  Regulations,  the term "benefit  plan  investor"
includes Plans and arrangements  that are not subject to ERISA, as well as Plans
that are subject to ERISA,  and  entities  whose  assets  include plan assets by
reason of a Plan's  investment in that entity.  Although it is possible that the
equity  participation by benefit plan investors in New Capital Securities on any
date will not be "significant" for purposes of the Plan Assets Regulations, such
result cannot be assured.

The New Capital  Securities may qualify as "publicly  offered  securities" under
the Plan Assets  Regulations  if at the time of the Exchange Offer they are also
"widely  held" and  "freely  transferable."  Under the  Regulations,  a class of
securities is "widely held" only if it is a class of securities that is owned by
100 or more investors independent of the issuer and of one another.  Although it
is possible  that at the time of the Exchange  Offer the New Capital  Securities
will be "widely  held,"  such result  cannot be  assured.  Whether a security is
"freely  transferable"  for purposes of the Regulations is a factual question to
be determined on the basis of all relevant  facts and  circumstances.  If at the
time of the  Exchange  Offer the New  Capital  Securities  qualify as  "publicly
offered  securities,"  the assets of the Trust should not be "plan  assets" with
respect  to  Plans  acquiring  New  Capital  Securities.  If at the  time of the
Exchange  Offer the New Capital  Securities do not qualify as "publicly  offered
securities,"  the  "plan  asset"  considerations   discussed  in  the  preceding
paragraphs could be applicable in connection with the investment by Plans in the
New Capital Securities.


                              PLAN OF DISTRIBUTION

Each  broker-dealer  that receives New Capital Securities for its own account in
connection  with the  Exchange  Offer must  acknowledge  that it will  deliver a
prospectus in connection  with any resale of such New Capital  Securities.  This
Prospectus,  as it may be amended or supplemented from time to time, may be used
by  Participating  Broker-  Dealers  during  the  period  referred  to  below in
connection with resales of New Capital  Securities  received in exchange for Old
Capital  Securities  if  such  Old  Capital  Securities  were  acquired  by such
Participating Broker-Dealers for their own accounts as a result of market-making
activities  or other trading  activities.  The Company and the Trust have agreed
that this  Prospectus,  as it may be amended or supplemented  from time to time,
may be used by a Participating  Broker-Dealer in connection with resales of such
New Capital  Securities  for a period ending 90 days after the  Expiration  Date
(subject to extension under certain limited circumstances  described herein) or,
if earlier,  when all such New Capital  Securities have been disposed of by such
Participating Broker-Dealer.  However, a Participating Broker-Dealer who intends
to use this Prospectus in connection  with the resale of New Capital  Securities
received in exchange for Old Capital  Securities  pursuant to the Exchange Offer
must  notify the  Company or the Trust,  or cause the Company or the Trust to be
notified,  on or  prior  to the  Expiration  Date,  that  it is a  Participating
Broker-Dealer.  Such notice may be given in the space  provided for that purpose
in the Letter of Transmittal or may be delivered to the Exchange Agent at one of
the addresses set forth herein under "The Exchange  Offer--Exchange  Agent." See
"The Exchange Offer--Resales of New Capital Securities."

The Company or the Trust will not receive any cash proceeds from the issuance of
the New Capital Securities  offered hereby.  New Capital Securities  received by
broker-dealers  for their own accounts in connection with the Exchange Offer may
be sold from time to time in one or more  transactions  in the  over-the-counter
market, in negotiated transactions,  through the writing of options on the New
Capital Securities or a combination of such methods of resale,  at market prices
prevailing at the time of resale,  at prices related to such prevailing  market
prices or at negotiated prices.  Any such  resale may be made  directly to
purchasers  or to or through brokers or dealers who may receive  compensation in
the form of  commissions or concessions  from any such  broker-dealer  and/or
the purchasers of any such New Capital Securities.

Any broker-dealer  that resells New Capital  Securities that were received by it
for its own  account in  connection  with the  Exchange  Offer and any broker or
dealer that participates in a distribution of such New Capital Securities may be
deemed to be an "underwriter"  within the meaning of the Securities Act, and any
profit on any such  resale of New  Capital  Securities  and any  commissions  or
concessions  received  by any such  persons  may be  deemed  to be  underwriting
compensation  under the Securities Act. The Letter of Transmittal states that by
acknowledging   that  it  will  deliver  and  by  delivering  a  prospectus,   a
broker-dealer will not be deemed to admit that it is an "underwriter" within the
meaning of the Securities Act.

                              NOTICE TO INVESTORS

Because of the following  restriction,  purchasers  are advised to consult legal
counsel  prior to making  any  offer,  resale or pledge or  transfer  of Capital
Securities.  Each  holder  of the  New  Capital  Securities,  by its  acceptance
thereof, will be deemed to have acknowledged, represented to and agreed with the
Trust and the Company as follows:

It (a) is not itself, and is not acquiring Capital Securities with "plan assets"
of,  an  employee  benefit  or other  plan  subject  to Title I of the  Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), or Section 4975 of
the Internal  Revenue Code of 1986, as amended (the "Code") (each, a "Plan),  or
an entity whose underlying  assets include "plan assets" by reason of any Plan's
investment  in the  entity (a "Plan  Asset  Entity"),  or (b) is  acquiring  and
holding the Capital Securities in a transaction that is not otherwise prohibited
by either ERISA or the Code. The Capital Securities will bear legends reflecting
the above restrictions.

his  conduct was  unlawful.  Article 9 of the  Virginia  Stock  Corporation  Act
provides  limitations on damages  payable by officers and  directors,  except in
cases of willful  misconduct or knowing violation of criminal law or any federal
or state securities law.

ITEM 22. UNDERTAKINGS

Each of the  undersigned  Registrants  hereby  undertakes  that, for purposes of
determining  any liability  under the Securities  Act of 1933, as amended,  each
filing of a  Registrant's  annual  report  pursuant to Section  13(a) or Section
15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing
of an employee  benefit  plan's annual  report  pursuant to Section 15(d) of the
Securities  Exchange  Act of 1934) that is  incorporated  by  reference  in this
Registration  Statement  shall  be  deemed  to be a new  registration  statement
relating to the securities  offered herein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

Insofar as indemnification  for liabilities  arising under the Securities Act of
1933 may be permitted to  directors,  officers and  controlling  persons of each
undersigned Registrant pursuant to the provisions, or otherwise, each Registrant
has been advised that in the opinion of the Securities  and Exchange  Commission
such  indemnification  is against  public policy as expressed in the Act and is,
therefore,  unenforceable. In the event that a claim for indemnification against
such  liabilities  (other than the  payment by each  undersigned  Registrant  of
expenses incurred or paid by a director,  officer of controlling  person of each
Registrant  in the  successful  defense of any action,  suit or  proceeding)  is
asserted by such director,  officer or controlling person in connection with the
securities being registered,  each Registrant will, unless in the opinion of its
counsel the matter has been settled by the  controlling  precedent,  submit to a
court of appropriate  jurisdiction the question whether such  indemnification by
it is against  public policy as expressed in the Act and will be governed by the
final adjudication of such issue.

The  undersigned  Registrants  hereby  undertake  to  respond  to  requests  for
information  that is incorporated  by reference into the Prospectus  pursuant to
Item 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such
request, and to send the incorporated documents by first class mail or other
equally prompt means.  This includes information contained in documents filed
subsequent to the effective date of the registration statement through the date
of responding to the request.

The  undersigned   Registrants   hereby  undertake  to  supply  by  means  of  a
post-effective  amendment  all  information  concerning a  transaction,  and the
company  being  acquired  or involved  therein,  that was not the subject of and
included in the registration statement when it became effective.

                                  (i)       if any Capital Securities are held
         in book-entry form, the related Definitive Securities shall be
         presented to the Trustee (if an arrangement with the Depositary has
         been maintained) by the Property Trustee in exchange for one or more

         aggregate principal amount equal to the aggregate principal amount of
         all outstanding Securities, to be registered in the name of the
         Depositary, or a custodian therefor, or its nominee, and delivered by
         the Trustee to the Depositary for crediting to the accounts of its
         participants pursuant to the instructions of the Administrative
         Trustees; the Company upon any such presentation shall execute one or
         more Global Securities in such aggregate principal amount and deliver
         the same to the Trustee for authentication and delivery in accordance
         with this Indenture; and payments on the Securities issued as a Global
         Security will be made to the Depositary; and

                                 (ii)       if any Capital Securities are held
         in certificated form, the related Definitive Securities may be
         presented to the Trustee by the Property Trustee and any Capital
         Security certificate which represents Capital Securities other than
         Capital Securities in book-entry form ("Non Book-Entry Capital
         Securities") will be deemed to represent beneficial interests in
         Securities presented to the Trustee by the Property Trustee having an
         aggregate principal amount equal to the aggregate liquidation amount of



                                       19

<PAGE>


         the Non Book-Entry Capital Securities until such Capital Security
         certificates are presented to the Security Registrar for transfer or
         reissuance, at which time such Capital Security certificates will be
         cancelled and a Security, registered in the name of the holder of the
         Capital Security certificate, with an aggregate principal amount equal
         to the aggregate liquidation amount of the Capital Security certificate
         cancelled, will be executed by the Company and delivered to the Trustee
         for authentication and delivery in accordance with this Indenture. Upon
         the issuance of such Securities, Securities with an equivalent
         aggregate principal amount that were presented by the Property Trustee
         to the Trustee will be deemed to have been cancelled.

                  (b) The Global Securities shall represent the aggregate amount
of outstanding Securities from time to time endorsed thereon; provided, that the
aggregate amount of outstanding Securities represented thereby may from time to
time be reduced or increased, as appropriate, to reflect exchanges and
prepayments. Any endorsement of a Global Security to reflect the amount of any
increase or decrease in the amount of outstanding Securities represented thereby
shall be made by the Trustee, in accordance with instructions given by the
Company as required by this Section 2.05.

                  (c) The Global Securities may be transferred, in whole but not
in part, only to another nominee of the Depositary, or to a successor Depositary
selected or approved by the Company or to a nominee of such successor
Depositary.

                  (d) If at any time the Depositary notifies the Company that it
is unwilling or unable to continue as Depositary or the Depositary has ceased to
be a clearing agency registered under the Exchange Act, and a successor
Depositary is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such condition, as the case may be, the
Company will execute, and the Trustee, upon receipt of a Company Order, will
authenticate and make available for delivery the Definitive Securities, in
authorized denominations, and in an aggregate principal amount equal to the
principal amount of the


                                       20

<PAGE>



Global Security in exchange for such Global Security. If there is an Event of
Default, the Depositary shall have the right to exchange the Global Securities
for Definitive Securities. In addition, the Company may at any time determine
that the Securities shall no longer be represented by a Global Security. In the
event of such an Event of Default or such a determination, the Company shall
execute, and subject to Section 2.07, the Trustee, upon receipt of an Officers'
Certificate evidencing such determination by the Company, will authenticate and
make available for delivery the Definitive Securities, in authorized
denominations, and in an aggregate principal amount equal to the principal
amount of the Global Security in exchange for such Global Security. Upon the
exchange of the Global Security for such Definitive Securities, in authorized
denominations, the Global Security shall be cancelled by the Trustee. Such
Definitive Securities issued in exchange for the Global Security shall be
registered in such names and in such authorized denominations as the Depositary,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee. The Trustee shall deliver such Definitive Securities
to the Depositary for delivery to the Persons in whose names such Definitive
Securities are so registered.

                  SECTION 2.06.  Interest.

                  (a) Each Security will bear interest at the rate of 8.71% per
annum (the "Coupon Rate") from the most recent date to which interest has been
paid or, if no interest has been paid, from January 13, 1997, until the
principal thereof becomes due and payable, and on any overdue principal and (to
the extent that payment of such interest is enforceable under applicable law) on
any overdue installment of interest at the Coupon Rate, compounded
semi-annually, payable (subject to the provisions of Article XVI) semi-annually
in arrears on January 1 and July 1 of each year (each, an "Interest Payment
Date") commencing on July 1, 1997 to the Person in whose name such Security or
any predecessor Security is registered, at the close of business on the regular
record date for such interest installment, which shall be the date fifteen days
prior to the relevant Interest Payment Date.


                                       21

<PAGE>

                  (b) Interest will be computed on the basis of a 360-day year
consisting of twelve 30-day months and, for any period of less than a full
calendar month, the number of days elapsed in such month. In the event that any
Interest Payment Date falls on a day that is not a Business Day, then payment of
interest payable on such date will be made on the next succeeding day which is a
Business Day (and without any interest or other payment in respect of any such
delay), with the same force and effect as if made on such date.

                  (c) During such time as the Property Trustee is the holder of
any Securities, the Company shall pay any additional amounts on the Securities
as may be necessary in order that the amount of Distributions then due and
payable by Markel Capital Trust on the outstanding Trust Securities shall not be
reduced as a result of any additional taxes, duties and other governmental
charges to which Markel Capital Trust has become subject as a result of a Tax
Event ("Additional Sums").

                  SECTION 2.07.  Transfer and Exchange.

                  (a) Transfer Restrictions. The Series A Securities, and those
Series B Securities with respect to which any Person described in Section
2.04(b)(A), (B) or (C) is the beneficial owner, may not be transferred except in
compliance with any legend contained in Exhibit A unless otherwise determined by
the Company in accordance with applicable law. Until the Securities are
registered under the Securities Act, the Securities may be transferred only in
blocks having an aggregate principal amount of not less than $100,000. Any such
transfer of the Securities in a block having an aggregate principal amount of
less than $100,000 shall be deemed to be void and of no legal effect whatsoever.
Any such transferee shall be deemed not to be holder of such Securities for any
purpose, including but not limited to the receipt of payments on such
Securities, and such transferee shall be deemed to have no interest whatsoever
in such Securities. Upon any distribution of the Securities following a
Dissolution Event, the Company and the Trustee shall enter into a supplemental
indenture pursuant to Section 9.01 to provide for the transfer restrictions and
procedures with respect to the Securities substantially similar to those
contained in the Declaration to the extent applicable in the circumstances
existing at such time.

Definitive Securities and Global Securities issued upon any registration of
transfer or exchange of Definitive Securities or Global Securities shall be the
valid obligations of the Company, evidencing the same debt, and entitled to the
same benefits under this Indenture, as the Definitive Securities or Global
Securities surrendered upon such registration of transfer or exchange.

                  No service charge shall be made to a holder for any
registration of transfer or exchange, but the Company may require payment of a
sum sufficient to cover any transfer tax or similar governmental charge payable
in connection therewith.

                  The Company shall not be required to (i) issue, register the
transfer of or exchange Securities during a period beginning at the opening of
business 15 days before the day of mailing of a notice of prepayment or any
notice of selection of Securities for prepayment under Article XIV hereof and
ending at the close of business on the day of such mailing; or (ii) register the
transfer of or exchange any Security so selected for prepayment in whole or in
part, except the unprepaid portion of any Security being prepaid in part.

                  Prior to due presentment for the registration of a transfer of
any Security, the Trustee, any agent and the Company may deem and treat the
Person in whose name any Security is registered as the absolute owner of such
Security for the purpose of receiving payment of principal of and premium, if
any, and interest on such Securities, and neither the Trustee, any agent nor the
Company shall be affected by notice to the contrary.

                  (c)      Exchange of Series A Securities for Series B
Securities.  The Series A Securities may be exchanged for Series B Securities
pursuant to the terms of the Exchange Offer.  The Trustee shall make the
exchange as follows:

<PAGE>


                  The Company shall present the Trustee with an Officers'
Certificate certifying the following:

                  (A)      upon issuance of the Series B Securities, the
                           transactions contemplated by the Exchange Offer have
                           been consummated: and

                  (B)      the principal amount of Series A Securities properly
                           tendered in the Exchange Offer that are represented
                           by a Global Security and the principal amount of
                           Series A Securities properly tendered in the Exchange
                           Offer that are represented by Definitive Securities,
                           the name of each holder of such Definitive
                           Securities, the principal amount at maturity properly
                           tendered in the Exchange Offer by each such holder
                           and the name and address to which Definitive
                           Securities for Series B Securities shall be
                           registered and sent for each such holder.

                  The Trustee, upon receipt of (i) such Officers' Certificate,
(ii) an Opinion of Counsel (x) to the effect that the Series B Securities have
been registered under Section 5 of the Securities Act and the Indenture has been
qualified under the Trust Indenture Act of 1939 and (y) with respect to the
matters set forth in Section 3(p) of the Registration Rights Agreement and (iii)
a Company Order, shall authenticate (A) a Global Security for Series B
Securities in aggregate principal amount equal to the aggregate principal amount
of Series A Securities represented by a Global Security indicated in such
Officers' Certificate as having been properly tendered and (B) Definitive
Securities representing Series B Securities registered in the names of, and in
the principal amounts indicated in, such Officers' Certificate.

                  If the principal amount at maturity of the Global Security for
the Series B Securities is less than the principal amount at maturity of the
Global Security for the Series A Securities, the Trustee shall make an
endorsement on such Global Security for the Series A Securities indicating a
reduction in the principal amount at maturity represented thereby.

                  The Trustee shall deliver such Definitive Securities for
Series B Securities to the holders thereof as indicated in such Officers'
Certificate.

                  SECTION 2.08.  Replacement Securities.

                  If any mutilated Security is surrendered to the Trustee, or
the Company and the Trustee receive evidence to their satisfaction of the
destruction, loss or theft of any Security, the Company shall issue and the
Trustee shall authenticate a replacement Security if the Trustee's requirements
for replacements of Securities are met. An indemnity bond must be supplied by
the holder that is sufficient in the judgment of the Trustee and the Company to
protect the Company, the Trustee and any authenticating agent from any loss that
any of them may suffer if a Security is replaced.  The Company or the Trustee
may charge for its expenses in replacing a Security.

                  Every replacement Security is an obligation of the Company and
shall be entitled to all of the benefits of this Indenture equally and
proportionately with all other Securities duly issued hereunder.

                  SECTION 2.09.  Treasury Securities.

                  In determining whether the holders of the required principal
amount of Securities have concurred in any direction, waiver or consent,
Securities owned by the Company or any Affiliate of the Company shall be
considered as though not outstanding, except that for purposes of determining
whether the Trustee shall be protected in relying on any such direction, waiver
or consent, only Securities that a Responsible Officer of the Trustee actually
knows to be so owned shall be so considered.

                  SECTION 2.10.  Temporary Securities.

                  Pending the preparation of Definitive Securities, the Company
may execute, and upon Company Order the Trustee shall authenticate and make
available for delivery, temporary Securities that are printed, typewritten,
lithographed, mimeographed or otherwise reproduced, in any authorized
denomination, substantially of the tenor of the definitive Securities in lieu of
which they are issued and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Securities may
determine, as conclusively evidenced by their execution of such Securities.

                  If temporary Securities are issued, the Company shall cause
Definitive Securities to be prepared without unreasonable delay. The Definitive
Securities shall be printed, typewritten, lithographed or engraved, or provided
by any combination thereof, or in any other manner permitted by the rules and
regulations of any applicable securities exchange, all as determined by the
officers executing such Definitive Securities. After the preparation of
Definitive Securities, the temporary Securities shall be exchangeable for
Definitive Securities upon surrender of the temporary Securities at the office
or agency maintained by the Company for such purpose pursuant to Section 3.02
hereof, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities, the Company shall execute, and the Trustee shall
authenticate and make available for delivery, in exchange therefor the same
aggregate principal amount of Definitive Securities of authorized denominations.
Until so exchanged, the temporary Securities shall in all respects be entitled
to the same benefits under this Indenture as Definitive Securities.

                  SECTION 2.11.  Cancellation.

                  The Company at any time may deliver Securities to the Trustee
for cancellation. The Trustee and no one else shall cancel all Securities
surrendered for registration of transfer, exchange, payment, replacement or
cancellation and shall retain or destroy cancelled Securities in accordance with
its normal practices (subject to the record retention requirement of the
Exchange Act) unless the Company directs them to be returned to it. The Company
may not issue new Securities to replace Securities that have been redeemed or
paid or that have been delivered to the Trustee for cancellation. All cancelled
Securities not destroyed by the Trustee shall be delivered to the Company.

                  SECTION 2.12.  Defaulted Interest.

                  Any interest on any Security that is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the holder
on the relevant regular record date by virtue of having been such holder; and
such Defaulted Interest shall be paid by the Company, at its election, as
provided in clause (a) or clause (b) below:

                  (a) The Company may make payment of any Defaulted Interest on
         Securities to the Persons in whose names such Securities (or their
         respective Predecessor Securities) are registered at the close of
         business on a special record date for the payment of such Defaulted
         Interest, which shall be fixed in the following manner: the Company
         shall notify the Trustee in writing of the amount of Defaulted Interest
         proposed to be paid on each such Security and the date of the proposed
         payment, and at the same time the Company shall deposit with the
         Trustee an amount of money equal to the aggregate amount proposed to be
         paid in respect of such Defaulted Interest or shall make arrangements
         satisfactory to the Trustee for such deposit prior to the date of the
         proposed payment, such money when deposited to be held in trust for the
         benefit of the Persons entitled to such Defaulted Interest as in this
         clause provided. Thereupon the Trustee shall fix a special record date
         for the payment of such Defaulted Interest which shall not be more than
         15 nor less than 10 days prior to the date of the proposed payment and
         not less than 10 days after the receipt by the Trustee of the notice of
         the proposed payment. The Trustee shall promptly notify the Company of
         such special record date and, in the name and at the expense of the
         Company, shall cause notice of the proposed payment of such Defaulted
         Interest and the special record date therefor to be mailed, first class
         postage prepaid, to each Securityholder at his or her address as it
         appears in the Security Register, not less than 10 days prior to such
         special record date. Notice of the proposed payment of such Defaulted
         Interest and the special record date therefor having been mailed as
         aforesaid, such Defaulted Interest shall be paid to the Persons in
         whose names such Securities (or their respective Predecessor
         Securities) are registered on such special record date and shall be no
         longer payable pursuant to the following clause (b).

<PAGE>


                  (b) The Company may make payment of any Defaulted Interest on
any Securities in any other lawful manner not inconsistent with the requirements
of any securities exchange on which such Securities may be listed, and upon such
notice as may be required by such exchange, if, after notice given by the
Company to the Trustee of the proposed payment pursuant to this clause, such
manner of payment shall be deemed practicable by the Trustee.

                  SECTION 2.13.  CUSIP Numbers.

                  The Company in issuing the Securities may use "CUSIP" numbers
(if then generally in use), and, if so, the Trustee shall use "CUSIP" numbers in
notices of prepayment as a convenience to Securityholders; provided that any
such notice may state that no representation is made as to the correctness of
such numbers either as printed on the Securities or as contained in any notice
of a prepayment and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such prepayment shall not be affected
by any defect in or omission of such numbers. The Company will promptly notify
the Trustee of any change in the CUSIP numbers.

                                  ARTICLE III.

                       PARTICULAR COVENANTS OF THE COMPANY

                  SECTION 3.01.     Payment of Principal, Premium and Interest

                  The Company covenants and agrees for the benefit of the
holders of the Securities that it will duly and punctually pay or cause to be
paid the principal of and premium, if any, and interest on the Securities at the
place, at the respective times and in the manner provided herein. The Company
further covenants to pay any and all amounts including, without limitation,
Liquidated Damages, if any, on the dates and in the manner required under the
Registration Rights Agreement.

                  SECTION 3.02.  Offices for Notices and Payments, etc.

                  So long as any of the Securities remains outstanding, the
Company will maintain in the Borough of Manhattan, The City of New York, an
office or agency where the Securities may be presented for payment, an office or
agency where the Securities may be presented for registration of transfer and
for exchange as in this Indenture provided and an office or agency where notices
and demands to or upon the Company in respect of the Securities or of this
Indenture may be served. The Company will give to the Trustee written notice of
the location of any such office or agency and of any change of location thereof.
Until otherwise designated from time to time by the Company in a notice to the
Trustee, any such office or agency for all of the above purposes shall be the
office or agency of the Trustee in the Borough of Manhattan, The City of New
York. In case the Company shall fail to maintain any such office or agency in
the Borough of Manhattan, The City of New York, or shall fail to give such
notice of the location or of any change in the location thereof, presentations
and demands may be made and notices may be served at the principal corporate
trust office of the Trustee.

                  In addition to any such office or agency, the Company may from
time to time designate one or more offices or agencies outside the Borough of
Manhattan, The City of New York, where the Securities may be presented for
registration of transfer and for exchange in the manner provided in this
Indenture, and the Company may from time to time rescind such designation, as
the Company may deem desirable or expedient; provided, however, that no such
designation or rescission shall in any manner relieve the Company of its
obligation to maintain any such office or agency in the Borough of Manhattan,
The City of New York, for the purposes above mentioned. The Company will give to
the Trustee prompt written notice of any such designation or rescission thereof;
provided, further, that the Company shall at all times maintain a paying agent
in each such office or agency.

                           shall agree with the Trustee, subject to the
                           provision of this Section 3.04,

                           (1)      that it will hold all sums held by it as

                                    Securities (whether such sums have been paid

                                    on the Securities) in trust for the benefit

                           (2)      that it will give the Trustee notice of any
                                    failure by the Company (or by any other
                                    obligor on the Securities) to make any
                                    payment of the principal of and premium or
                                    interest on the Securities when the same
                                    shall be due and payable.

                           benefit of the holders of the Securities a sum
                           sufficient to pay such principal, premium or interest
                           so becoming due and will notify the Trustee of any
                           failure to take such action and of any failure by the

                                    If the Trustee shall elect not to afford
                           such applicants access to such information, the
                           Trustee shall, upon the written request of such
                           applicants, mail to each Securityholder whose name
                           and address appear in the information preserved at
                           the time by the Trustee in accordance with the
                           provisions of subsection (a) of this Section 4.02 a
                           copy of the form of proxy or other communication
                           which is specified in such request with reasonable
                           promptness after a tender to the Trustee of the
                           material to be mailed and of payment, or provision
                           for the payment, of the reasonable expenses of
                           mailing, unless within five days after such tender,
                           the Trustee shall mail to such applicants and file
                           with the Commission, together with a copy of the
                           material to be mailed, a written statement to the
                           effect that, in the opinion of the Trustee, such
                           mailing would be contrary to the best interests of
                           the holders of all Securities or would be in
                           violation of applicable law. Such written statement
                           shall specify the basis of such opinion. If the
                           Commission, after opportunity for a hearing upon the
                           objections specified in the written statement so
                           filed, shall enter an order refusing to sustain any
                           of such objections or if, after the entry of an order
                           sustaining one or more of such objections, the
                           Commission shall find, after notice and opportunity
                           for hearing, that all the objections so sustained
                           have been met and shall enter an order so declaring,
                           the Trustee shall mail copies of such material to all
                           such Securityholders with reasonable promptness after
                           the entry of such order and the renewal of such
                           tender; otherwise the Trustee shall be relieved of
                           any obligation or duty to such applicants respecting
                           their application.

                  (c)      Each and every holder of Securities, by receiving and
                           holding the same, agrees with the Company and the
                           Trustee that neither the Company nor the Trustee nor
                           any paying agent shall be held accountable by reason

                           consent to the entry of an order for relief in an
                           involuntary case under any such law, or shall
                           consent to the appointment of or taking possession
                           by a receiver, liquidator, assignee, trustee,
                           custodian, sequestrator (or other similar
                           official) of the Company or of any substantial
                           part of its property, or shall make any general
                           assignment for the benefit of creditors, or shall
                           fail generally to pay its debts as they become
                           due.

                  If an Event of Default with respect to Securities at the time
outstanding occurs and is continuing, then in every such
case the Trustee or the holders of not less than 25% in aggregate principal
amount of the Securities then outstanding may declare the principal amount of
all Securities to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by the holders of the outstanding
Securities), and upon any such declaration the same shall become immediately due
and payable.

                  The foregoing provisions, however, are subject to the
condition that if, at any time after the principal of the Securities shall have
been so declared due and payable, and before any judgment or decree for the
payment of the moneys due shall have been obtained or entered as hereinafter
provided, (i) the Company shall pay or shall deposit with the Trustee a sum
sufficient to pay (A) all matured installments of interest upon all the
Securities and the principal of and premium, if any, on any and all Securities
which shall have become due otherwise than by acceleration (with interest upon
such principal and premium, if any, and, to the extent that payment of such
interest is enforceable under applicable law, on overdue installments of
interest, at the same rate as the rate of interest specified in the Securities
to the date of such payment or deposit) and (B) such amount as shall be
sufficient to pay to the Trustee and each predecessor Trustee all amounts
payable pursuant to Section 6.06, and (ii) any and all Events of Default under
the Indenture shall have been cured, waived or otherwise remedied as provided
herein, then, in every such case, the holders of a majority in aggregate
principal amount of the Securities then outstanding, by written notice to the
Company and to the Trustee, may rescind and annul such declaration and its
consequences, but no such waiver or rescission and annulment shall extend to or
shall affect any subsequent default or shall impair any right consequent
thereon.

                  In case the Trustee shall have proceeded to enforce any right
under this Indenture and such proceedings shall have been discontinued or
abandoned because of such rescission or annulment or for any other reason or
shall have been determined adversely to the Trustee, then and in every such case
the Company, the Trustee and the holders of the Securities shall be restored
respectively to their several positions and rights hereunder, and all rights,
remedies and powers of the Company, the Trustee and the holders of the
Securities shall continue as though no such proceeding had been taken.

                  SECTION 5.02.     Payment of Securities on Default; Suit
                                    Therefor.

                  The Company covenants that (a) in case default shall be made
in the payment of any installment of interest upon any of the Securities as and
when the same shall become due and payable, and such default shall have
continued for a period of 30 days, or (b) in case default shall be made in the
payment of the principal of or premium, if any, on any of the Securities as and
when the same shall have become due and payable, whether at maturity of the
Securities or upon prepayment or by declaration of acceleration of maturity or
otherwise, then, upon demand of the Trustee, the Company will pay to the
Trustee, for the benefit of the holders of the Securities, the whole amount that
then shall have become due and payable on all such Securities for principal and
premium, if any, or interest, or both, as the case may be, with interest upon
the overdue principal and premium, if any, and (to the extent that payment of
such interest is enforceable under applicable law and, if the Securities are
held by Markel Capital Trust or a trustee of such trust, without duplication of
any other amounts paid by Markel Capital Trust or a trustee in respect thereof)
upon the overdue installments of interest at the rate borne by the Securities;
and, in addition thereto, such further amount as shall be sufficient to cover
the costs and expenses of collection, including a reasonable compensation to the
Trustee, its agents, attorneys and counsel, and any expenses or liabilities
incurred by the Trustee hereunder other than through its negligence or bad
faith.

                  In case the Company shall fail forthwith to pay such amounts
upon such demand, the Trustee, in its own name and as trustee of an express
trust, shall be entitled and empowered to institute any actions or proceedings
at law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceeding to judgment or final decree, and may
enforce any such judgment or final decree against the Company or any other
obligor on the Securities and collect in the manner provided by law out of the
property of the Company or any other obligor on the Securities wherever situated
the moneys adjudged or decreed to be payable.

                  In case there shall be pending proceedings for the bankruptcy
or for the reorganization of the Company or any other obligor on the Securities
under Title 11, United States Code, or any other applicable law, or in case a
receiver or trustee shall have been appointed for the property of the Company or
such other obligor, or in the case of any other similar judicial proceedings
relative to the Company or other obligor upon the Securities, or to the
creditors or property of the Company or such other obligor, the Trustee,
irrespective of whether the principal of the Securities shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand pursuant to the provisions of
this Section 5.02, shall be entitled and empowered, by intervention in such
proceedings or otherwise, to file and prove a claim or claims for the whole
amount of principal and interest owing and unpaid in respect of the Securities
and, in case of any judicial proceedings, to file such proofs of claim and other
papers or documents as may be necessary or advisable in order to have the claims
of the Trustee (including any claim for all amounts payable pursuant to Section
6.06 to the Trustee and each predecessor Trustee) and of the Securityholders
allowed in such judicial proceedings relative to the Company or any other
obligor on the Securities, or to the creditors or property of the Company or
such other obligor, unless prohibited by applicable law and

regulations, to vote on behalf of the holders of the Securities in any election
of a trustee or a standby trustee in arrangement, reorganization, liquidation or
other bankruptcy or insolvency proceedings or Person performing similar
functions in comparable proceedings, and to collect and receive any moneys or
other property payable or deliverable on any such claims, and to distribute the
same after the deduction of its charges and expenses; and any receiver, assignee
or trustee in bankruptcy or reorganization is hereby authorized by each of the
Securityholders to make such payments to the Trustee, and, in the event that the
Trustee shall consent to the making of such payments directly to the
Securityholders, to pay to the Trustee such amounts as shall be sufficient to
pay to the Trustee and each predecessor Trustee all amounts payable pursuant to
Section 6.06.

                  Nothing herein contained shall be construed to authorize the
Trustee to authorize or consent to or accept or adopt on behalf of any
Securityholder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or the rights of any holder thereof or to
authorize the Trustee to vote in respect of the claim of any Securityholder in
any such proceeding.

                  All rights of action and of asserting claims under this
Indenture, or under any of the Securities, may be enforced by the Trustee
without the possession of any of the Securities, or the production thereof in
any trial or other proceeding relative thereto, and any such suit or proceeding
instituted by the Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment shall be for the ratable benefit of
the holders of the Securities.

                  In any proceedings brought by the Trustee (and also any
proceedings involving the interpretation of any provision of this Indenture to
which the Trustee shall be a party) the Trustee shall be held to represent all
the holders of the Securities, and it shall not be necessary to make any holders
of the Securities parties to any such proceedings.

                  SECTION 5.03.     Application of Moneys Collected by Trustee.

                  Any moneys collected by the Trustee shall be applied in the
order following, at the date or dates fixed by the Trustee for the distribution
of such moneys, upon presentation of the Securities in respect of which moneys
have been collected, and stamping thereon the payment, if only partially paid,
and upon surrender thereof if fully paid:

                  First: To the payment of all amounts due the Trustee under
Section 6.06, including the costs and expenses of collection applicable to the
Securities and reasonable compensation to the Trustee, its agents, attorneys and
counsel, and of all other expenses and liabilities incurred, and all advances
made, by the Trustee except as a result of its negligence or bad faith;

                  Second: To the payment of all Senior Indebtedness of the
Company if and to the extent required by Article XV;

                  Third: In case the principal of the outstanding Securities in
respect of which moneys have been collected shall not have become due and be
unpaid, to the payment of the amounts then due and unpaid upon Securities for
principal of (and premium, if any) and interest on the Securities, in respect of
which or for the benefit of which money has been collected, ratably, without
preference of priority of any kind, according to the amounts due on such
Securities for principal (and premium, if any) and interest, respectively; and

                  Fourth: To the Company.

                  SECTION 5.04.  Proceedings by Securityholders.

                  Except as contemplated by this Section 5.04, no holder of any
Security shall have any right by virtue of or by availing of any provision of
this Indenture to institute any suit, action or proceeding in equity or at law
upon or under or with respect to this Indenture or for the appointment of a
receiver or trustee, or for any other remedy hereunder, unless such holder


                                       46

<PAGE>


previously shall have given to the Trustee written notice of an Event of Default
and of the continuance thereof with respect to the Securities specifying such
Event of Default, as hereinbefore provided, and unless also the holders of not
less than 25% in aggregate principal amount of the Securities then outstanding
shall have made written request upon the Trustee to institute such action, suit
or proceeding in its own name as Trustee hereunder and shall have offered to the
Trustee such reasonable indemnity as it may require against the costs, expenses
and liabilities to be incurred therein or thereby, and the Trustee for 60 days
after its receipt of such notice, request and offer of indemnity shall have
failed to institute any such action, suit or proceeding, it being understood and
intended, and being expressly covenanted by the taker and holder of every
Security with every other taker and holder and the Trustee, that no one or more
holders of Securities shall have any right in any manner whatever by virtue of
or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of any other holder of Securities, or to obtain or seek to
obtain priority over or preference to any other such holder, or to enforce any
right under this Indenture, except in the manner herein provided and for the
equal, ratable and common benefit of all holders of Securities.

                  Notwithstanding any other provisions in this Indenture,
however, the right of any holder of any Security to receive payment of the
principal of (premium, if any) and interest on such Security, on or after the
same shall have become due and payable, or to institute suit for the enforcement
of any such payment, shall not be impaired or affected without the consent of
such holder and by accepting a Security hereunder it is expressly understood,
intended and covenanted by the taker and holder of every Security with every
other such taker and holder and the Trustee, that no one or more holders of
Securities shall have any right in any manner whatsoever by virtue or by
availing of any provision of this Indenture to affect, disturb or prejudice the
rights of the holders of any other Securities, or to obtain or seek to obtain
priority over or preference to any other such holder, or to enforce any right
under this Indenture, except in the manner herein provided and for the equal,
ratable and common benefit of all holders of Securities. For the protection and
enforcement of the provisions of this Section, each and every Securityholder and
the Trustee shall be entitled to such relief as can be given either at law or in
equity.

                  The Company and the Trustee acknowledge that pursuant to the
Declaration, the holders of Capital Securities are entitled, in the
circumstances and subject to the limitations set forth therein, to commence a
Direct Action with respect to any Event of Default under this Indenture and the
Securities.

                  SECTION 5.05.  Proceedings by Trustee.

                  In case an Event of Default occurs with respect to Securities
and is continuing, the Trustee may in its discretion proceed to protect and
enforce the rights vested in it by this Indenture by such appropriate judicial
proceedings as the Trustee shall deem most effectual to protect and enforce any
of such rights, either by suit in equity or by action at law or by proceeding in
bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in this Indenture or in aid of the exercise of any power
granted in this Indenture, or to enforce any other legal or equitable right
vested in the Trustee by this Indenture or by law.

                  SECTION 5.06.  Remedies Cumulative and Continuing.

                  All powers and remedies given by this Article V to the Trustee
or to the Securityholders shall, to the extent permitted by law, be deemed
cumulative and not exclusive of any other powers and remedies available to the
Trustee or the holders of the Securities, by judicial proceedings or otherwise,
to enforce the performance or observance of the covenants and agreements
contained in this Indenture or otherwise established with respect to the
Securities, and no delay or omission of the Trustee or of any holder of any of
the Securities to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or an acquiescence
therein; and, subject to the provisions of Section 5.04, every power and remedy
given by this Article V or by law to the Trustee or to the Securityholders may
be exercised from time to time, and as often as shall be deemed expedient, by
the Trustee or by the Securityholders.

                  SECTION 5.07.     Direction of Proceedings and Waiver of
                                    Defaults by Majority of Securityholders.

                  The holders of a majority in aggregate principal amount of the
Securities at the time outstanding shall have the right to direct the time,
method, and place of conducting any proceeding for any remedy available to the
Trustee, or exercising any trust or power conferred on the Trustee; provided,
however, that (subject to the provisions of Section 6.01) the Trustee shall have
the right to decline to follow any such direction if the Trustee shall determine
that the action so directed would be unjustly prejudicial to the holders not
taking part in such direction or if the Trustee being advised by counsel
determines that the action or proceeding so directed may not lawfully be taken
or if the Trustee in good faith by its board of directors or trustees, executive
committee, or a trust committee of directors or trustees and/or Responsible
Officers shall determine that the action or proceedings so directed would
involve the Trustee in personal liability. Prior to any declaration accelerating
the maturity of the Securities, the holders of a majority in aggregate principal
amount of the Securities at the time outstanding may on behalf of the holders of
all of the Securities waive any past default or Event of Default and its
consequences except a default (a) in the payment of principal of or premium, if
any, or interest on any of the Securities or (b) in respect of covenants or
provisions hereof which cannot be modified or amended without the consent of the
holder of each Security affected; provided, however, that if the Securities are
held by the Property Trustee, such waiver or modification to such waiver shall
not be effective until the holders of a majority in aggregate liquidation amount
of Trust Securities shall have consented to such waiver or modification to such
waiver; provided further, that if the consent of the holder of each outstanding
Security is required, such waiver shall not be effective until each holder of
the Trust Securities shall have consented to such waiver. Upon any such waiver,
the default covered thereby shall be deemed to be cured for all purposes of this
Indenture and the Company, the Trustee and the holders of the Securities shall
be restored to their former positions and rights hereunder, respectively; but no
such waiver shall extend to any subsequent or other default or impair any right
consequent thereon. Whenever any default or Event of Default hereunder shall
have been waived as permitted by this Section 5.07, said default or Event of
Default shall for all purposes of the Securities and this Indenture be deemed to
have been cured and to be not continuing.

                  SECTION 5.08.  Notice of Defaults.

                  The Trustee shall, within 90 days after the occurrence of a
default with respect to the Securities known to the Trustee, mail to all
Securityholders, as the names and addresses of such holders appear upon the
Security register, notice of all defaults known to the Trustee, unless such
defaults shall have been cured before the giving of such notice (the term
"defaults" for the purpose of this Section 5.08 being hereby defined to be the
events specified in clauses (a), (b), (c), (d) and (e) of Section 5.01, not
including periods of grace, if any, provided for therein, and irrespective of
the giving of written notice specified in clause (c) of Section 5.01); and
provided that, except in the case of default in the payment of the principal of
or premium, if any, or interest on any of the Securities, the 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 Trustee in good faith determines that the withholding of such
notice is in the interests of the Securityholders; and provided further, that in
the case of any default of the character specified in Section 5.01(c) no such
notice to Securityholders shall be given until at least 60 days after the
occurrence thereof but shall be given within 90 days after such occurrence.


                  SECTION 5.09.  Undertaking to Pay Costs.

                  All parties to this Indenture agree, and each holder of any
Security by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for any
action taken or omitted by it as Trustee, the filing by any party litigant in


                                       50

<PAGE>


such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees and expenses, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section 5.09 shall not apply to any suit instituted
by the Trustee, to any suit instituted by any Securityholder, or group of
Securityholders, holding in the aggregate more than 10% in aggregate principal
amount of the Securities outstanding, or to any suit instituted by any
Securityholder for the enforcement of the payment of the principal of (or
premium, if any) or interest on any Security against the Company on or after the
same shall have become due and payable.

                                   ARTICLE VI. CONCERNING THE TRUSTEE

                  SECTION 6.01.  Duties and Responsibilities of Trustee.

                  With respect to the holders of the Securities issued
hereunder, the Trustee, prior to the occurrence of an Event of Default and after
the curing or waiving of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture. In case an Event of Default has occurred (which has not
been cured or waived) the Trustee shall exercise such of the rights and powers
vested in it by this Indenture, and use the same degree of care and skill in
their exercise, as a prudent man would exercise or use under the circumstances
in the conduct of his own affairs.

                  No provision of this Indenture shall be construed to relieve
the Trustee from liability for its own negligent action, its own negligent
failure to act or its own willful misconduct, except that

                  (a)      prior to the occurrence of an Event of Default and
                           after the curing or waiving of all Events of Default
                           which may have occurred

<PAGE>

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

                           (2)      in the absence of bad faith on the part of
                                    the Trustee, the 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 Trustee and conforming to
                                    the requirements of this Indenture; but, in
                                    the case of any such certificates or
                                    opinions that by any provision hereof are
                                    specifically required to be furnished to the
                                    Trustee, the Trustee shall be under a duty
                                    to examine the same to determine whether or
                                    not they conform to the requirements of this
                                    Indenture;

                  (b)      the Trustee shall not be liable for any error of
                           judgment made in good faith by a Responsible Officer
                           or Officers of the Trustee, unless it shall be proved
                           that the Trustee was negligent in ascertaining the
                           pertinent facts; and

                  (c)      the 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 Securityholders pursuant to Section 5.07,
                           relating to the time, method and place of
                           conducting any proceeding for any remedy available
                           to the Trustee, or exercising any trust or power
                           conferred upon the Trustee, under this Indenture.

<PAGE>


                  None of the provisions contained in this Indenture shall
require the 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 there is reasonable ground for believing that
the repayment of such funds or liability is not reasonably assured to it under
the terms of this Indenture and that adequate indemnity against such risk is not
reasonably assured to it.

                  SECTION 6.02.  Reliance on Documents, Opinions, etc.

                  Except as otherwise provided in Section 6.01:

                  (a)      the Trustee may rely and shall be protected in
                           acting or refraining from acting upon any
                           resolution, certificate, statement, instrument,
                           opinion, report, notice, request, consent, order,
                           bond, note, debenture or other paper or document
                           believed by it to be genuine and to have been
                           signed or presented by the proper party or
                           parties;

                  (b)      any request, direction, order or demand of the
                           Company mentioned herein may be sufficiently
                           evidenced by an Officers' Certificate (unless
                           other evidence in respect thereof be herein
                           specifically prescribed); and any Board Resolution
                           may be evidenced to the Trustee by a copy thereof
                           certified by the Secretary or an Assistant
                           Secretary  of the Company;

                  (c)      the Trustee may consult with counsel of its selection
                           and any advice or Opinion of Counsel shall be full
                           and complete authorization and protection in respect
                           of any action taken or suffered omitted by it
                           hereunder in good faith and in accordance with such
                           advice or Opinion of Counsel;

                  (d)      the Trustee shall be under no obligation to
                           exercise any of the rights or powers vested in it
                           by this Indenture at the request, order or
                           direction of any of the Securityholders, pursuant
                           to the provisions of this Indenture, unless such
                           Securityholders shall have offered to the Trustee
                           reasonable security or indemnity against the
                           costs, expenses and liabilities which may be
                           incurred therein or thereby;

                  (e)      the Trustee shall not be liable for any action
                           taken or omitted by it in good faith and believed
                           by it to be authorized or within the discretion or
                           rights or powers conferred upon it by this
                           Indenture; nothing contained herein shall,
                           however, relieve the Trustee of the obligation,
                           upon the occurrence of an Event of Default (that
                           has not been cured or waived), to exercise such of
                           the rights and powers vested in it by this
                           Indenture, and to use the same degree of care and
                           skill in their exercise, as a prudent man would
                           exercise or use under the circumstances in the
                           conduct of his own affairs;

                  (f)      the Trustee shall not be bound to make any
                           investigation into the facts or matters stated in
                           any resolution, certificate, statement,
                           instrument, opinion, report, notice, request,
                           consent, order, approval, bond, debenture, coupon
                           or other paper or document, unless requested in
                           writing to do so by the holders of a majority in
                           aggregate principal amount of the outstanding
                           Securities; provided, however, that if the payment
                           within a reasonable time to the Trustee of the
                           costs, expenses or liabilities likely to be
                           incurred by it in the making of such investigation
                           is, in the opinion of the Trustee, not reasonably
                           assured to the Trustee by the security afforded to
                           it by the terms of this Indenture, the Trustee may
                           require reasonable indemnity against such expense
                           or liability as a condition to so proceeding; and

                  (g)      the Trustee may execute any of the trusts or powers
                           hereunder or perform any duties hereunder either
                           directly or by or through agents (including any
                           Authenticating Agent) or attorneys, and the Trustee
                           shall not be responsible for any misconduct or
                           negligence on the part of any such agent or attorney
                           appointed by it with due care.

                  SECTION 6.03.  No Responsibility for Recitals, etc.

                  The recitals contained herein and in the Securities (except in
the certificate of authentication of the Trustee or the Authenticating Agent)
shall be taken as the statements of the Company and the Trustee and the
Authenticating Agent assume no responsibility for the correctness of the same.
The Trustee and the Authenticating Agent make no representations as to the
validity or sufficiency of this Indenture or of the Securities. The Trustee and
the Authenticating Agent shall not be accountable for the use or application by
the Company of any Securities or the proceeds of any Securities authenticated
and delivered by the Trustee or the Authenticating Agent in conformity with the
provisions of this Indenture.

                  SECTION 6.04. Trustee, Authenticating Agent, Paying Agents,
                                 Transfer Agents or Registrar May Own
                                 Securities.

                  The Trustee or any Authenticating Agent or any paying agent or
any transfer agent or any Security registrar, in its individual or any other
capacity, may become the owner or pledgee of Securities with the same rights it
would have if it were not Trustee, Authenticating Agent, paying agent, transfer
agent or Security registrar.

                  SECTION 6.05.  Moneys to be Held in Trust.

                  Subject to the provisions of Section 11.04, all moneys
received by the Trustee or any paying agent shall, until used or applied as
herein provided, be held in trust for the purpose for which they were received,
but need not be segregated from other funds except to the extent required by
law. The Trustee and any paying agent shall be under no liability for interest
on any money received by it hereunder except as otherwise agreed in writing with
the Company.

                  SECTION 6.06.  Compensation and Expenses of Trustee.

                  The Company, as borrower, covenants and agrees to pay to the
Trustee from time to time, and the Trustee shall be entitled to, such
compensation as shall be agreed to in writing between the Company and the
Trustee (which shall not be limited by any provision of law in regard to the
compensation of a trustee of an express trust), and the Company will pay or
reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in accordance with
any of the provisions of this Indenture (including the reasonable compensation
and the expenses and disbursements of its counsel and of all Persons not
regularly in its employ) except any such expense, disbursement or advance as may
arise from its negligence or bad faith. The Company also covenants to indemnify
each of the Trustee or any predecessor Trustee (and its officers, agents,
directors and employees) for, and to hold each of them harmless against, any and
all loss, damage, claim, liability or expense including taxes (other than taxes
based on the income of the Trustee) incurred without negligence or bad faith on
the part of the Trustee and arising out of or in connection with the acceptance
or administration of this trust, including the costs and expenses of defending
itself against any claim of liability in the premises. The obligations of the
Company under this Section 6.06 shall constitute additional indebtedness
hereunder. Such additional indebtedness shall be secured by a lien prior to that
of the Securities upon all property and funds held or collected by the Trustee
as such, except funds held in trust for the benefit of the holders of particular
Securities.

                  When the Trustee incurs expenses or renders services in
connection with an Event of Default specified in Section 5.01(d) or Section
5.01(e), the expenses (including the reasonable charges and expenses of its
counsel) and the compensation for the services are intended to constitute
expenses of administration under any applicable federal or state bankruptcy,
insolvency or other similar law.

                  The provisions of this Section shall survive the resignation
or removal of the Trustee and the defeasance or other termination of this
Indenture.

                  SECTION 6.07.  Officers' Certificate as Evidence.

                  Except as otherwise provided in Sections 6.01 and 6.02,
whenever in the administration of the provisions of this Indenture the Trustee
shall deem it necessary or desirable that a matter be proved or established
prior to taking or omitting any action hereunder, such matter (unless other
evidence in respect thereof is herein specifically prescribed) may, in the
absence of negligence or bad faith on the part of the Trustee, be deemed to be
conclusively proved and established by an Officers' Certificate delivered to the
Trustee, and such certificate, in the absence of negligence or bad faith on the
part of the Trustee, shall be full warrant to the Trustee for any action taken
or omitted by it under the provisions of this Indenture upon the faith thereof.

                  SECTION 6.08.  Conflicting Interest of Trustee.

                  If the Trustee has or shall acquire any "conflicting interest"
within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and
the Company shall in all respects comply with the provisions of Section 310(b)
of the Trust Indenture Act.

                  SECTION 6.09.  Eligibility of Trustee.

                  The Trustee hereunder shall at all times be a corporation
organized and doing business under the laws of the United States of America or
any state or territory thereof or of the District of Columbia or a corporation
or other Person permitted to act as trustee by the Commission authorized under
such laws to exercise corporate trust powers, having a combined capital and
surplus of at least 50 million U.S. dollars ($50,000,000) and subject to
supervision or examination by federal, state, territorial, or District of
Columbia authority. If such corporation publishes reports of condition at least
annually, pursuant to law or to the requirements of the aforesaid supervising or
examining authority, then for the purposes of this Section 6.09 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.

                  The Company may not, nor may any Person directly or indirectly
controlling, controlled by, or under common control with the Company, serve as
Trustee.

                  In case at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 6.09, the Trustee shall resign
immediately in the manner and with the effect specified in Section 6.10.

                  SECTION 6.10.     Resignation or Removal of Trustee.

                  (a)      The Trustee, or any trustee or trustees hereafter
                           appointed, may at any time resign by giving
                           written notice of such resignation to the Company
                           and by mailing notice thereof to the holders of
                           the Securities at their addresses as they shall
                           appear on the Security register.  Upon receiving
                           such notice of resignation, the Company shall
                           promptly appoint a successor trustee or trustees
                           by written instrument, in duplicate, one copy of
                           which instrument shall be delivered to the
                           resigning Trustee and one copy to the successor
                           trustee.  If no successor trustee shall have been
                           so appointed and have accepted appointment within
                           60 days after the mailing of such notice of
                           resignation to the affected Securityholders, the
                           resigning Trustee may petition any court of
                           competent jurisdiction for the appointment of a
                           successor trustee, or any Securityholder who has
                           been a bona fide holder of a Security for at least
                           six months may, subject to the provisions of
                           Section 5.09, on behalf of himself and all others
                           similarly situated, petition any such court for
                           the appointment of a successor trustee.  Such
                           court may thereupon, after such notice, if any, as
                           it may deem proper and prescribe, appoint a
                           successor trustee.

                  (b)      In case at any time any of the following shall
                           occur:

                           (1)      the Trustee shall fail to comply with the
                                    provisions of Section 6.08 after written
                                    request therefor by the Company or by any
                                    Securityholder who has been a bona fide
                                    holder of a Security or Securities for at
                                    least six months, or

                           (2)      the Trustee shall cease to be eligible in
                                    accordance with the provisions of Section
                                    6.09 and shall fail to resign after written
                                    request therefor by the Company or by any
                                    such Securityholder, or

                           (3)      the Trustee shall become incapable of
                                    acting, or shall be adjudged a bankrupt or
                                    insolvent, or a receiver of the Trustee or
                                    of its property shall be appointed, or any
                                    public officer shall take charge or control
                                    of the Trustee or of its property or affairs
                                    for the purpose of rehabilitation,
                                    conservation or liquidation,

                           then, in any such case, the Company may remove the
                           Trustee and appoint a successor trustee by written
                           instrument, in duplicate, one copy of which
                           instrument shall be delivered to the Trustee so
                           removed and one copy to the successor trustee, or,
                           subject to the provisions of Section 5.09, any
                           Securityholder who has been a bona fide holder of a
                           Security for at least six months may, on behalf of
                           himself and all others similarly situated, petition
                           any court of competent jurisdiction for the removal
                           of the Trustee and the appointment of a successor
                           trustee. Such court may thereupon, after such notice,
                           if any, as it may deem proper and prescribe, remove
                           the Trustee and appoint a successor trustee.

                  (c)      The holders of a majority in aggregate principal
                           amount of the Securities at the time outstanding
                           may at any time remove the Trustee and nominate a
                           successor trustee, which shall be deemed appointed
                           as successor trustee unless within 10 days after
                           such nomination the Company objects thereto or if
                           no successor trustee shall have been so appointed
                           and shall have accepted appointment within 30 days
                           after such removal, in which case the Trustee so
                           removed or any Securityholder, upon the terms and
                           conditions and otherwise as in subsection (a) of
                           this Section 6.10 provided, may petition any court
                           of competent jurisdiction for an appointment of a
                           successor trustee.

                  (d)      Any resignation or removal of the Trustee and
                           appointment of a successor trustee pursuant to any of
                           the provisions of this Section 6.10 shall become
                           effective upon acceptance of appointment by the
                           successor trustee as provided in Section 6.11.

                  SECTION 6.11.  Acceptance by Successor Trustee.

                  Any successor trustee appointed as provided in Section 6.10
shall execute, acknowledge and deliver to the Company and to its predecessor
trustee an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the retiring trustee shall become effective and such
successor trustee, without any further act, deed or conveyance, shall become
vested with all the rights, powers, duties and obligations of its predecessor
hereunder, with like effect as if originally named as trustee herein; but,
nevertheless, on the written request of the Company or of the successor trustee,
the trustee ceasing to act shall, upon payment of any amounts then due it
pursuant to the provisions of Section 6.06, execute and deliver an instrument
transferring to such successor trustee all the rights and powers of the trustee

                                       60

so ceasing to act and shall duly assign, transfer and deliver to such successor
trustee all property and money held by such retiring trustee thereunder. Upon
request of any such successor trustee, the Company shall execute any and all
instruments in writing for more fully and certainly vesting in and confirming to
such successor trustee all such rights and powers. Any trustee ceasing to act
shall, nevertheless, retain a lien upon all property or funds held or collected
by such trustee to secure any amounts then due it pursuant to the provisions of
Section 6.06.

                  No successor trustee shall accept appointment as provided in
this Section 6.11 unless at the time of such acceptance such successor trustee
shall be qualified under the provisions of Section 6.08 and eligible under the
provisions of Section 6.09.

                  Upon acceptance of appointment by a successor trustee as
provided in this Section 6.11, the Company shall mail notice of the succession
of such trustee hereunder to the holders of Securities at their addresses as
they shall appear on the Security register. If the Company fails to mail such
notice within 10 days after the acceptance of appointment by the successor
trustee, the successor trustee shall cause such notice to be mailed at the
expense of the Company.

                  SECTION 6.12.  Successor by Merger, etc.

                  Any corporation into which the Trustee may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Trustee shall be a
party, or any corporation succeeding to all or substantially all of the
corporate trust business of the Trustee, shall be the successor of the Trustee
hereunder without the execution or filing of any paper or any further act on the
part of any of the parties hereto.

                  In case at the time such successor to the Trustee shall
succeed to the trusts created by this Indenture any Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor trustee, and deliver such

                                       61

<PAGE>

Securities so authenticated; and in case at that time any of the Securities
shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor hereunder or in the name
of the successor trustee; and in all such cases such certificates shall have the
full force which the Securities or this Indenture elsewhere provides that the
certificate of the Trustee shall have; provided, however, that the right to
adopt the certificate of authentication of any predecessor Trustee or
authenticate Securities in the name of any predecessor Trustee shall apply only
to its successor or successors by merger, conversion or consolidation.

                  SECTION 6.13.     Limitation on Rights of Trustee as a
                                    Creditor.

                  The Trustee shall comply with Section 311(a) of the Trust
Indenture Act of 1939, excluding any creditor relationship described in Section
311(b) of the Trust Indenture Act of 1939. A Trustee who has resigned or been
removed shall be subject to Section 311(a) of the Trust Indenture Act of 1939 to
the extent included therein.

                  SECTION 6.14.  Authenticating Agents.

                  There may be one or more Authenticating Agents appointed by
the Trustee upon the request of the Company with power to act on its behalf and
subject to its direction in the authentication and delivery of Securities issued
upon exchange or registration of transfer thereof as fully to all intents and
purposes as though any such Authenticating Agent had been expressly authorized
to authenticate and deliver Securities; provided, that the Trustee shall have no
liability to the Company for any acts or omissions of the Authenticating Agent
with respect to the authentication and delivery of Securities. Any such
Authenticating Agent shall at all times be a corporation organized and doing
business under the laws of the United States or of any state or territory
thereof or of the District of Columbia authorized under such laws to act as
Authenticating Agent, having a combined capital and surplus of at least
$5,000,000 and being subject to supervision or examination by federal, state,

                                       62

<PAGE>

territorial or District of Columbia authority. If such corporation publishes
reports of condition at least annually pursuant to law or the requirements of
such authority, then for the purposes of this Section 6.14 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. If at
any time an Authenticating Agent shall cease to be eligible in accordance with
the provisions of this Section, it shall resign immediately in the manner and
with the effect herein specified in this Section.

                  Any corporation into which any Authenticating Agent may be
merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, consolidation or conversion to which any
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate trust business of any Authenticating Agent, shall be the successor of
such Authenticating Agent hereunder, if such successor corporation is otherwise
eligible under this Section 6.14 without the execution or filing of any paper or
any further act on the part of the parties hereto or such Authenticating Agent.

                  Any Authenticating Agent may at any time resign by giving
written notice of resignation to the Trustee and to the Company. The Trustee may
at any time terminate the agency of any Authenticating Agent by giving written
notice of termination to such Authenticating Agent and to the Company. Upon
receiving such a notice of resignation or upon such a termination, or in case at
any time any Authenticating Agent shall cease to be eligible under this Section
6.14, the Trustee may, and upon the request of the Company shall, promptly
appoint a successor Authenticating Agent eligible under this Section 6.14, shall
give written notice of such appointment to the Company and shall mail notice of
such appointment to all Securityholders as the names and addresses of such
holders appear on the Security Register. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all rights,
powers, duties and responsibilities of its predecessor hereunder, with like
effect as if originally named as Authenticating Agent herein.

                                       63

<PAGE>

                  The Company, as borrower, agrees to pay to any Authenticating
Agent from time to time reasonable compensation for its services. Any
Authenticating Agent shall have no responsibility or liability for any action
taken by it as such in accordance with the directions of the Trustee.

                                  ARTICLE VII.
                         CONCERNING THE SECURITYHOLDERS

                  SECTION 7.01.  Action by Securityholders.

                  Whenever in this Indenture it is provided that the holders of
a specified percentage in aggregate principal amount of the Securities may take
any action (including the making of any demand or request, the giving of any
notice, consent or waiver or the taking of any other action) the fact that at
the time of taking any such action the holders of such specified percentage have
joined therein may be evidenced (a) by any instrument or any number of
instruments of similar tenor executed by such Securityholders in person or by
agent or proxy appointed in writing, or (b) by the record of such holders of
Securities voting in favor thereof at any meeting of such Securityholders duly
called and held in accordance with the provisions of Article VIII, or (c) by a
combination of such instrument or instruments and any such record of such a
meeting of such Securityholders.

                  If the Company shall solicit from the Securityholders any
request, demand, authorization, direction, notice, consent, waiver or other
action, the Company may, at its option, as evidenced by an Officers'
Certificate, fix in advance a record date for the determination of
Securityholders entitled to give such request, demand, authorization, direction,
notice, consent, waiver or other action, but the Company shall have no
obligation to do so. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other action may be given
before or after the record date, but only the Securityholders of record at the
close of business on the record date shall be deemed to be Securityholders for
the purposes of determining whether Securityholders of the requisite proportion
of Outstanding Securities have authorized or agreed or consented to such

                                       64

<PAGE>


request, demand, authorization, direction, notice, consent, waiver or other
action, and for that purpose the Outstanding Securities shall be computed as of
the record date; provided, however, that no such authorization, agreement or
consent by such Securityholders on the record date shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture
not later than six months after the record date.


                  SECTION 7.02.  Proof of Execution by Securityholders.

                  Subject to the provisions of Sections 6.01, 6.02 and 8.05,
proof of the execution of any instrument by a Securityholder or his agent or
proxy shall be sufficient if made in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee or in such manner as shall be
satisfactory to the Trustee. The ownership of Securities shall be proved by the
Security Register or by a certificate of the Security registrar. The Trustee may
require such additional proof of any matter referred to in this Section as it
shall deem necessary.

                  The record of any Securityholders' meeting shall be proved in
the manner provided in Section 8.06.

                  SECTION 7.03.  Who Are Deemed Absolute Owners.

                  Prior to due presentment for registration of transfer of any
Security, the Company, the Trustee, any Authenticating Agent, any paying agent,
any transfer agent and any Security registrar may deem the Person in whose name
such Security shall be registered upon the Security Register to be, and may
treat him as, the absolute owner of such Security (whether or not such Security
shall be overdue) for the purpose of receiving payment of or on account of the
principal of and premium, if any, and interest on such Security and for all
other purposes; and neither the Company nor the Trustee nor any Authenticating
Agent nor any paying agent nor any transfer agent nor any Security registrar
shall be affected by any notice to the contrary. All such payments so made to
any holder for the time being or upon his order shall be valid, and, to the
extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for moneys payable upon any such Security.

                  SECTION 7.04.    Securities Owned by Company Deemed Not
                                   Outstanding.

                  In determining whether the holders of the requisite aggregate
principal amount of Securities have concurred in any direction, consent or
waiver under this Indenture, Securities which are owned by the Company or any
other obligor on the Securities or by any Person directly or indirectly
controlling or controlled by or under direct or indirect common control with the
Company, except for the Securities owned by or on behalf of Markel Capital
Trust, or any other obligor on the Securities shall be disregarded and deemed
not to be outstanding for the purpose of any such determination; provided that
for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, consent or waiver, only Securities which a
Responsible Officer of the Trustee actually knows are so owned shall be so
disregarded. Securities so owned which have been pledged in good faith may be
regarded as outstanding for the purposes of this Section 7.04 if the pledgee
shall establish to the satisfaction of the Trustee the pledgee's right to vote
such Securities and that the pledgee is not the Company or any such other
obligor or Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company or any such other obligor. In
the case of a dispute as to such right, any decision by the Trustee taken upon
the advice of counsel shall be full protection to the Trustee.

                  SECTION 7.05.    Revocation of Consents; Future Holders
                                   Bound.

                  At any time prior to (but not after) the evidencing to the
Trustee, as provided in Section 7.01, of the taking of any action by the holders
of the percentage in aggregate principal amount of the Security specified in
this Indenture in connection with such action, any holder of a Security (or any
Security issued in whole or in part in exchange or substitution therefor) the
serial number of which is shown by the evidence to be included in the Securities
the holders of which have consented to such action may, by filing written notice

                                       66

<PAGE>


with the Trustee at its principal office and upon proof of holding as provided
in Section 7.02, revoke such action so far as concerns such Security (or so far
as concerns the principal amount represented by any exchanged or substituted
Security). Except as aforesaid, any such action taken by the holder of any
Security shall be conclusive and binding upon such holder and upon all future
holders and owners of such Security, and of any Security issued in exchange or
substitution therefor, irrespective of whether or not any notation in regard
thereto is made upon such Security or any Security issued in exchange or
substitution therefor.

                                  ARTICLE VIII.
                            SECURITYHOLDERS' MEETINGS

                  SECTION 8.01.  Purpose of Meetings

from time to time pursuant to the provisions of this Article VIII for any of the
following purposes:

                  (a)      to give any notice to the Company or to the Trustee,
                           or to give any directions to the Trustee, or to
                           consent to the waiving of any Default hereunder and
                           its consequences, or to take any other action
                           authorized to be taken by Securityholders pursuant to
                           any of the provisions of Article V;

                  (b)      to remove the Trustee and nominate a successor
                           trustee pursuant to the provisions of Article VI;

                  (c)      to consent to the execution of an indenture or
                           indentures supplemental hereto pursuant to the
                           provisions of Section 9.02; or

                  (d)      to take any other action authorized to be taken by or
                           on behalf of the holders of any specified aggregate
                           principal amount of such Securities under any other
                           provision of this Indenture or under applicable law.

                  SECTION 8.02.  Call of Meetings by Trustee.

                  The Trustee may at any time call a meeting of Securityholders
to take any action specified in Section 8.01, to be held at such time and at
such place in the Borough of Manhattan, The City of New York, as the Trustee
shall determine. Notice of every meeting of the Securityholders, setting forth
the time and the place of such meeting and in general terms the action proposed
to be taken at such meeting, shall be mailed to holders of Securities at their
addresses as they shall appear on the Securities Register. Such notice shall be
mailed not less than 20 nor more than 180 days prior to the date fixed for the
meeting.

                  SECTION 8.03.    Call of Meetings by Company or
                                   Securityholders.

                  In case at any time the Company pursuant to a resolution of
the Board of Directors, or the holders of at least 10% in aggregate principal
amount of the Securities then outstanding, shall have requested the Trustee to
call a meeting of Securityholders, by written request setting forth in
reasonable detail the action proposed to be taken at the meeting, and the
Trustee shall not have mailed the notice of such meeting within 20 days after
receipt of such request, then the Company or such Securityholders may determine
the time and the place in the Borough of Manhattan, The City of New York, for
such meeting and may call such meeting to take any action authorized in Section
8.01, by mailing notice thereof as provided in Section 8.02.

only Persons who shall be entitled to be present or to speak at any meeting of
Securityholders shall be the Persons entitled to vote at such meeting and their

                  SECTION 8.05.  Regulations.

                  Notwithstanding any other provisions of this Indenture, the
Trustee may make such reasonable regulations as it may deem advisable for any
meeting of Securityholders, in regard to proof of the holding of Securities and
of the appointment of proxies, and in regard to the appointment and duties of
inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall think fit.

                  The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Securityholders as provided in Section 8.03, in which case the
Company or the Securityholders calling the meeting, as the case may be, shall in
like manner appoint a temporary chairman. A permanent chairman and a permanent
secretary of the meeting shall be elected by majority vote of the meeting.

                  Subject to the provisions of Section 8.04, at any meeting each
holder of Securities or proxy therefor shall be entitled to one vote for each
$1,000 principal amount of Securities held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not outstanding and ruled by the chairman of the meeting
to be not outstanding. The chairman of the meeting shall have no right to vote
other than by virtue of Securities held by him or instruments in writing as
aforesaid duly designating him as the person to vote on behalf of other
Securityholders. Any meeting of Securityholders duly called pursuant to the
provisions of Section 8.02 or 8.03 may be adjourned from time to time by a
majority of those present, whether or not constituting a quorum, and the meeting
may be held as so adjourned without further notice.

permanent chairman of the meeting shall appoint two inspectors of votes who
shall count all votes cast at the meeting for or against any resolution and who

thereto the ballots voted at the meeting. The holders of the Series A Securities
and the Series B Securities shall vote for all purposes as a single class.

                  Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

                           covenants, agreements and obligations of the Company
                           pursuant to Article X hereof;

                           provide for a particular period of grace after
                           default (which period may be shorter or longer than

                           provide for an immediate enforcement upon such
                           default or may limit the remedies available to the

                           registrable as to principal only) and to provide for
                           exchangeability of such Securities with the
                           Securities issued hereunder in fully registered form
                           and to make all appropriate changes for such purpose;

                  (d)      to cure any ambiguity or to correct or supplement
                           any provision contained herein or in any
                           supplemental indenture which may be defective or
                           inconsistent with any other provision contained

                  Any amendment to this Indenture authorized by the provisions
of this Section 9.01 may be executed by the Company and the Trustee without the
consent of the holders of any of the Securities at the time outstanding,
notwithstanding any of the provisions of Section 9.02.

                  SECTION 9.02.  With Consent of Securityholders.

                  With the consent (evidenced as provided in Section 7.01) of
the holders of a majority in aggregate principal amount of the Securities at the
time outstanding, the Company, when authorized by a Board Resolution, and the
Trustee may from time to time and at any time amend this Indenture for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Indenture or of modifying in any manner the rights of
the holders of the Securities; provided, however, that no such amendment shall
without the consent of the holders of each Security then outstanding and
affected hereby (i) extend the Maturity Date of any Security, or reduce the rate

impair or affect the right of any Securityholder to institute suit for payment
thereof, or (ii) reduce the aforesaid percentage of Securities the holders of
which are required to consent to any such amendment to this Indenture, provided,
however, that if the Securities are held by Markel Capital Trust, such amendment
shall not be effective until the holders of a majority in liquidation amount of
Trust Securities shall have consented to such amendment; provided, further, that
if the consent of the holder of each outstanding Security is required, such
amendment shall not be effective until each holder of the Trust Securities shall
have consented to such amendment.

                  Upon the request of the Company accompanied by a copy of a
resolution of the Board of Directors certified by its Secretary or Assistant
Secretary authorizing the execution of any supplemental indenture affecting such
amendment, and upon the filing with the Trustee of evidence of the consent of
Securityholders as aforesaid, the Trustee shall join with the Company in the
execution of such supplemental indenture unless such supplemental indenture
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise, in which case the Trustee may in its discretion, but shall not be
obligated to, enter into such supplemental indenture.

                  Promptly after the execution by the Company and the Trustee of
any supplemental indenture pursuant to the provisions of this Section, the
Trustee shall transmit by mail, first class postage prepaid, a notice, prepared
by the Company, setting forth in general terms the substance of such
supplemental indenture, to the Securityholders as their names and addresses
appear upon the Security Register. Any failure of the Trustee to mail such
notice, or any defect therein, shall not, however, in any way impair or affect
the validity of any such supplemental indenture.

                  It shall not be necessary for the consent of the
Securityholders under this Section 9.02 to approve the particular form of any
proposed supplemental indenture, but it shall be sufficient if such consent
shall approve the substance thereof.

                  SECTION 9.03.    Compliance with Trust Indenture Act;
                                   Effect of Supplemental Indentures.

this Indenture shall be and be deemed to be modified and amended in accordance
therewith and the respective rights, limitations of rights, obligations, duties
and immunities under this Indenture of the Trustee, the Company and the holders
of Securities shall thereafter be determined, exercised and enforced hereunder
subject in all respects to such modifications and amendments and all the terms

this Article IX may bear a notation in form approved by the Trustee as to any
matter provided for in such supplemental indenture. If the Company or the
Trustee shall so determine, new Securities so modified as to conform, in the
opinion of the Trustee and the Board of Directors, to any modification of this
Indenture contained in any such supplemental indenture may be prepared and
executed by the Company, authenticated by the Trustee or the Authenticating
Agent and delivered in exchange for the Securities then outstanding.

                  SECTION 13.08.  Trust Indenture Act to Control.

                  If and to the extent that any provision of this Indenture

which is required to be included in this Indenture by any of Sections 310 to

                  SECTION 13.12.  Assignment.

                  The Company will have the right at all times to assign any of
its respective rights or obligations under this Indenture to a direct or
indirect wholly owned Subsidiary of the Company, provided that, in the event of
any such assignment, the Company, as the case may be, will remain liable for all
such obligations. Subject to the foregoing, the Indenture is binding upon and
inures to the benefit of the parties thereto and their respective successors and
assigns. This Indenture may not otherwise be assigned by the parties hereto.

                  SECTION 13.13.  Acknowledgement of Rights.

                  The Company acknowledges that, with respect to any Securities
held by Markel Capital Trust or a trustee of such trust, if the Property Trustee
of such Trust fails to enforce its rights under this Indenture as the holder of
the Securities held as the assets of Markel Capital Trust any holder of Capital
Securities may institute legal proceedings directly against the Company to
enforce such Property Trustee's rights under this Indenture without first
instituting any legal proceedings against such Property Trustee or any other
Person. Notwithstanding the foregoing, if an Event of Default has occurred and
is continuing and such event is attributable to the failure of the Company to
pay principal of or premium, if any, or interest on the Securities when due, the
Company acknowledges that a holder of Capital Securities may directly institute
a proceeding for enforcement of payment to such holder of the principal of or
premium, if any, or interest on the Securities having a principal amount equal
to the aggregate liquidation amount of the Capital Securities of such holder on
or after the respective due date specified in the Securities.

                  SECTION 14.01.  Special Event Prepayment.

                  If a Special Event has occurred and is continuing, then the

                                       87

less than 45 days written notice to the Trustee and (ii) not less than 30 days
nor more than 60 days written notice to the Securityholders, to prepay the
Securities, in whole (but not in part), at any time within 90 days following the

Following a Special Event, the Company shall take such action as is necessary to
promptly determine the Special Event Prepayment Price, including without
limitation the appointment by the Company of a Quotation Agent. The Special

principal amount of the Securities to be prepaid), plus, in each case, accrued
and unpaid interest thereon (including Additional Sums and Compounded Interest,

                  If the Securities are only partially prepaid pursuant to this
Section 14.02, the Securities will be prepaid pro rata or by lot or by any other
method utilized by the Trustee; provided that if at the time of prepayment, the
Securities are registered as a Global Security, the Depositary shall determine
in accordance with its procedures the principal amount of Securities held for
the account of its participants to be prepaid. The Optional Prepayment Price
shall be paid prior to 12:00 noon, New York City time, on the date of such
prepayment or at such earlier time as the Company determines, provided that the
Company shall deposit with the Trustee an amount sufficient to pay the Optional
Prepayment Price by 10:00 a.m., New York City time, on the date such Optional
Prepayment Price is to be paid.

                  (b) Notwithstanding the first sentence of Section 14.02, upon
the entry of an order for dissolution of Markel Capital Trust by a court of
competent jurisdiction, the Securities thereafter will be subject to optional
prepayment, in whole only, but not in part, on or after the Initial Optional
Prepayment Date, at the optional prepayment prices set forth in Section 14.02
and otherwise in accordance with this Article XIV.

                  SECTION 14.03.  No Sinking Fund.

                  The Securities are not entitled to the benefit of any sinking
fund.

                  SECTION 14.04.    Notice of Prepayment; Selection of
                                    Securities.

                  In case the Company shall desire to exercise the right to
prepay all, or, as the case may be, any part of the Securities in accordance
with their terms, it shall fix a date for prepayment and shall mail a notice of
such prepayment at least 30 and not more than 60 days prior to the date fixed
for prepayment to the holders of Securities so to be prepaid as a whole or in
part at their last addresses as the same appear on the Security Register. Such
mailing shall be by first class mail. The notice if mailed in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not
the holder receives such notice. In any case, failure to give such notice by
mail or any defect in the notice to the holder of any Security designated for
prepayment as a whole or in part shall not affect the validity of the
proceedings for the prepayment of any other Security.



                                       89

<PAGE>




                  Each such notice of prepayment shall specify the CUSIP number
of the Securities to be prepaid, the date fixed for prepayment, the prepayment
price at which the Securities are to be prepaid (or the method by which such
prepayment price is to be calculated), the place or places of payment that
payment will be made upon presentation and surrender of the Securities, that
interest accrued to the date fixed for prepayment will be paid as specified in
said notice, and that on and after said date interest thereon or on the portions
thereof to be prepaid will cease to accrue. If less than all the Securities are
to be prepaid the notice of prepayment shall specify the numbers of the
Securities to be prepaid. In case any Security is to be prepaid in part only,
the notice of prepayment shall state the portion of the principal amount thereof
to be prepaid and shall state that on and after the date fixed for prepayment,
upon surrender of such Security, a new Security or Securities in principal
amount equal to the unprepaid portion thereof will be issued.

                  Prior to 10:00 a.m., New York City time, on the prepayment
date specified in the notice of prepayment given as provided in this Section,
the Company will deposit with the Trustee or with one or more paying agents an
amount of money sufficient to prepay on the prepayment date all the Securities
so called for prepayment at the appropriate Prepayment Price, together with
accrued interest to the date fixed for prepayment.

                  The Company will give the Trustee notice not less than 45 days
prior to the prepayment date as to the aggregate principal amount of Securities
to be prepaid and the Trustee shall select, in such manner as in its sole
discretion it shall deem appropriate and fair, the Securities or portions
thereof (in integral multiples of $1,000, except as otherwise set forth in the
applicable form of Security) to be prepaid.

                  SECTION 14.05.    Payment of Securities Called for
                                    Prepayment.

                  If notice of prepayment has been given as provided in Section
14.04, the Securities or portions of Securities with respect to which such
notice has been given shall become due and payable on the date and at the place
or places stated in such notice at the applicable Prepayment Price, together
with interest accrued to the date fixed for prepayment (subject to the rights of
holders of Securities on the close of business on a regular record date in
respect of an Interest Payment Date occurring on or prior to the prepayment
date), and on and after said date (unless the Company shall default in the
payment of such Securities at the Prepayment Price, together with interest
accrued to said date) interest on the Securities or portions of Securities so
called for prepayment shall cease to accrue. On presentation and surrender of
such Securities at a place of payment specified in said notice, the said
Securities or the specified portions thereof shall be paid and prepaid by the
Company at the applicable Prepayment Price, together with interest accrued
thereon to the date fixed for prepayment (subject to the rights of holders of
Securities on the close of business on a regular record date in respect of an
Interest Payment Date occurring on or prior to the prepayment date).

                  Upon presentation of any Security prepaid in part only, the
Company shall execute and the Trustee shall authenticate and make available for
delivery to the holder thereof, at the expense of the Company, a new Security or
Securities of authorized denominations, in principal amount equal to the
unprepaid portion of the Security so presented.

                  SECTION 14.06.  Conditional Right to Advance Maturity.

         If a Tax Event occurs, then the Company will have the right (i) prior
to the termination of Markel Capital Trust, to advance the Maturity Date of the
Securities to the minimum extent required, but not to a date earlier than twenty
years from the Issue Date, or (ii) to terminate Markel Capital Trust (if not
previously terminated) and advance the Maturity Date of the Securities to the
minimum extent required, but not to a date earlier than forty years from the

                                       91

<PAGE>


Issue Date, in each case such that, in the written opinion of counsel
experienced in such matters delivered to the Company, after advancing the
Maturity Date, interest paid on the Securities shall be deductible for federal
income tax purposes (the action referred to in either clause (i) of (ii) above
being referred to herein as a "Tax Event Maturity Advancement").

         If a Tax Event occurs and in the written opinion of counsel to the
Company experienced in such matters there would in all cases, after effecting a
Tax Event Maturity Advancement, be more than an insubstantial risk that an
Adverse Tax Consequence would continue to exist, a Special Event shall be deemed
to have occurred and the Securities shall then be subject to prepayment in
accordance with the provisions of Section 14.01. The circumstances under which
the Company has the right to prepay the Securities in connection with a Tax
Event is referred to herein as a "Conditional Tax Redemption Event".


                                   ARTICLE XV.

                           SUBORDINATION OF SECURITIES

                  SECTION 15.01.  Agreement to Subordinate.

                  The Company covenants and agrees, and each holder of
Securities issued hereunder likewise covenants and agrees, that the Securities
shall be issued subject to the provisions of this Article XV; and each holder of
a Security, whether upon original issue or upon transfer or assignment thereof,
accepts and agrees to be bound by such provisions.

                  The payment by the Company of the principal of and premium, if
any, and interest on all Securities issued hereunder shall, to the extent and in
the manner hereinafter set forth, be subordinated and junior in right of payment
to the prior payment in full of all amounts with respect to Senior Indebtedness,
whether outstanding at the date of this Indenture or thereafter incurred.

                  No provision of this Article XV shall prevent the occurrence
of any Default or Event of Default hereunder.

                  SECTION 15.02.  Default on Senior Indebtedness.

                  In the event and during the continuation of any default by the
Company in the payment of principal, premium, interest or any other payment due
on any Senior Indebtedness, or in the event that the maturity of any Senior
Indebtedness has been accelerated because of a default, then, in either case, no
payment shall be made by the Company with respect to the principal (including
prepayments) of or premium, if any, or interest on the Securities.

                  In the event of the acceleration of the maturity of the
Securities, then no payment shall be made by the Company with respect to the
principal (including prepayments) of or premium, if any, or interest on the
Securities until the holders of all Senior Indebtedness outstanding at the time
of such acceleration shall receive payment in full of all amounts due in respect
of such Senior Indebtedness (including any amounts due upon acceleration).

                  In the event that, notwithstanding the foregoing, any payment
shall be received by the Trustee when such payment is prohibited by the
preceding paragraph of this Section 15.02, such payment shall be held in trust
for the benefit of, and shall be paid over or delivered to, the holders of
Senior Indebtedness or their respective representatives, or to the trustee or
trustees under any indenture pursuant to which any of such Senior Indebtedness
may have been issued, as their respective interests may appear, but only to the
extent of the amounts due in respect of such Senior Indebtedness and only to the
extent that the holders of the Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing, within 90 days of
such payment, of the amounts then due and owing on such Senior Indebtedness and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of such Senior Indebtedness.

                  SECTION 15.03.  Liquidation; Dissolution; Bankruptcy.

                  Upon any payment by the Company or distribution of assets of
the Company of any kind or character, whether in cash, property or securities,
to creditors upon any dissolution or winding-up or liquidation or reorganization
of the Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, all amounts due upon all Senior Indebtedness
of the Company shall first be paid in full, or payment thereof provided for in
money in accordance with its terms, before any payment is made by the Company on
account of the principal (and premium, if any) or interest on the Securities;
and upon any such dissolution or winding-up or liquidation or reorganization,
any payment by the Company, or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, to which the
Securityholders or the Trustee would be entitled to receive from the Company,
except for the provisions of this Article XV, shall be paid by the Company or by
any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person
making such payment or distribution, or by the Securityholders or by the Trustee
under this Indenture if received by them or it, directly to the holders of
Senior Indebtedness of the Company (pro rata to such holders on the basis of the
respective amounts of Senior Indebtedness held by such holders, as calculated by
the Company) or their representative or representatives, or to the trustee or
trustees under any indenture pursuant to which any instruments evidencing such
Senior Indebtedness may have been issued, as their respective interests may
appear, to the extent necessary to pay such Senior Indebtedness in full, in
money or money's worth, after giving effect to any concurrent payment or
distribution to or for the holders of such Senior Indebtedness, before any
payment or distribution is made to the Securityholders or to the Trustee.

                  In the event that, notwithstanding the foregoing, any payment
or distribution of assets of the Company of any kind or character, whether in
cash, property or securities, prohibited by the foregoing, shall be received by
the Trustee before all Senior Indebtedness is paid in full, or provision is made
for such payment in money in accordance with its terms, such payment or
distribution shall be held in trust for the benefit of and shall be paid over or


                                       94

delivered to the holders of such Senior Indebtedness or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing such Senior Indebtedness may have been issued,
and their respective interests may appear, as calculated by the Company, for
application to the payment of all Senior Indebtedness remaining unpaid to the
extent necessary to pay all amounts due in respect of such Senior Indebtedness
in full in money in accordance with its terms, after giving effect to any
concurrent payment or distribution to or for the benefit of the holders of such
Senior Indebtedness.

                  For purposes of this Article XV, the words "cash, property or
securities" shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation
provided for by a plan of reorganization or readjustment, the payment of which
is subordinated at least to the extent provided in this Article XV with respect
to the Securities to the payment of Senior Indebtedness that may at the time be
outstanding, provided that (i) such Senior Indebtedness is assumed by the new
corporation, if any, resulting from any such reorganization or readjustment, and
(ii) the rights of the holders of such Senior Indebtedness are not, without the
consent of such holders, altered by such reorganization or readjustment. The
consolidation of the Company with, or the merger of the Company into, another
Person or the liquidation or dissolution of the Company following the sale,
conveyance, transfer or lease of its property as an entirety, or substantially
as an entirety, to another Person upon the terms and conditions provided for in
Article X of this Indenture shall not be deemed a dissolution, winding-up,
liquidation or reorganization for the purposes of this Section 15.03 if such
other Person shall, as a part of such consolidation, merger, sale, conveyance,
transfer or lease, comply with the conditions stated in Article X of this
Indenture. Nothing in Section 15.02 or in this Section 15.03 shall apply to
claims of, or payments to, the Trustee under or pursuant to Section 6.06 of this
Indenture.

                  SECTION 15.04.  Subrogation.

                  Subject to the payment in full of all amounts due in respect
of Senior Indebtedness, the rights of the Securityholders shall be subrogated to
the rights of the holders of such Senior Indebtedness to receive payments or
distributions of cash, property or securities of the Company, as the case may
be, applicable to such Senior Indebtedness until the principal of (and premium,
if any) and interest on the Securities shall be paid in full; and, for the
purposes of such subrogation, no payments or distributions to the holders of
such Senior Indebtedness of any cash, property or securities to which the
Securityholders or the Trustee would be entitled except for the provisions of
this Article XV, and no payment over pursuant to the provisions of this Article
XV to or for the benefit of the holders of such Senior Indebtedness by
Securityholders or the Trustee, shall, as between the Company, its creditors
other than holders of Senior Indebtedness of the Company, and the holders of the
Securities, be deemed to be a payment by the Company to or on account of such
Senior Indebtedness. It is understood that the provisions of this Article XV are
and are intended solely for the purposes of defining the relative rights of the
holders of the Securities, on the one hand, and the holders of such Senior
Indebtedness, on the other hand.

                  Nothing contained in this Article XV or elsewhere in this
Indenture or in the Securities is intended to or shall impair, as between the
Company, its creditors other than the holders of Senior Indebtedness of the
Company, and the holders of the Securities, the obligation of the Company, which
is absolute and unconditional, to pay to the holders of the Securities the
principal of (and premium, if any) and interest on the Securities as and when
the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of the holders of the Securities
and creditors of the Company, as the case may be, other than the holders of
Senior Indebtedness of the Company, as the case may be, nor shall anything
herein or therein prevent the Trustee or the holder of any Security from
exercising all remedies otherwise permitted by applicable law upon default under
this Indenture, subject to the rights, if any, under this Article XV of the
holders of such Senior Indebtedness in respect of cash, property or securities
of the Company, as the case may be, received upon the exercise of any such
remedy.

                  Upon any payment or distribution of assets of the Company
referred to in this Article XV, the Trustee, subject to the provisions of
Article VI of this Indenture, and the Securityholders shall be entitled to
conclusively rely upon any order or decree made by any court of competent
jurisdiction in which such dissolution, winding-up, liquidation or
reorganization proceedings are pending, or a certificate of the receiver,
trustee in bankruptcy, liquidation trustee, agent or other Person making such
payment or distribution, delivered to the Trustee or to the Securityholders, for
the purposes of ascertaining the Persons entitled to participate in such
distribution, the holders of Senior Indebtedness and other indebtedness of the
Company, as the case may be, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article XV.


                  SECTION 15.05.    Trustee to Effectuate Subordination.

                  Each Securityholder by such Securityholder's acceptance
thereof authorizes and directs the Trustee on such Securityholder's behalf to
take such action as may be necessary or appropriate to effectuate the
subordination provided in this Article XV and appoints the Trustee such
Securityholder's attorney-in-fact for any and all such purposes.

                  SECTION 15.06.  Notice by the Company.

                  The Company shall give prompt written notice to a Responsible
Officer of the Trustee of any fact known to the Company that would prohibit the
making of any payment of monies to or by the Trustee in respect of the
Securities pursuant to the provisions of this Article XV. Notwithstanding the
provisions of this Article XV or any other provision of this Indenture, the
Trustee shall not be charged with knowledge of the existence of any facts that
would prohibit the making of any payment of monies to or by the Trustee in
respect of the Securities pursuant to the provisions of this Article XV, unless


                                       97

<PAGE>


and until a Responsible Officer of the Trustee shall have received written
notice thereof from the Company or a holder or holders of Senior Indebtedness or
from any trustee therefor; and before the receipt of any such written notice,
the Trustee, subject to the provisions of Article VI of this Indenture, shall be
entitled in all respects to assume that no such facts exist; provided, however,
that if the Trustee shall not have received the notice provided for in this
Section 15.06 at least two Business Days prior to the date upon which by the
terms hereof any money may become payable for any purpose (including, without
limitation, the payment of the principal of (or premium, if any) or interest on
any Security), then, anything herein contained to the contrary notwithstanding,
the Trustee shall have full power and authority to receive such money and to
apply the same to the purposes for which they were received, and shall not be
affected by any notice to the contrary that may be received by it within two
Business Days prior to such date.

                  The Trustee, subject to the provisions of Article VI of this
Indenture, shall be entitled to conclusively rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness of the Company, as the case may be (or a trustee on behalf of such
holder), to establish that such notice has been given by a holder of such Senior
Indebtedness or a trustee on behalf of any such holder or holders. In the event
that the Trustee determines in good faith that further evidence is required with
respect to the right of any Person as a holder of such Senior Indebtedness to
participate in any payment or distribution pursuant to this Article XV, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of such Senior Indebtedness held by
such Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this Article XV, and, if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

                  Upon any payment or distribution of assets of the Company
referred to in this Article XV, the Trustee and the Securityholders shall be
entitled to rely upon any order or decree entered by any court of competent
jurisdiction in which such insolvency, bankruptcy, receivership, liquidation,
reorganization, dissolution, winding up or similar case or proceeding is
pending, or a certificate of the trustee in bankruptcy, liquidating trustee,
custodian, receiver, assignee for the benefit of creditors, agent or other
Person making such payment or distribution, delivered to the Trustee or to the
Securityholders, for the purpose of ascertaining the Persons entitled to
participate in such payment or distribution, the holders of Senior Indebtedness
and other indebtedness of the Company, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article XV.


                  SECTION 15.07.    Rights of the Trustee; Holders of Senior
                                    Indebtedness.

                  The Trustee in its individual capacity shall be entitled to
all the rights set forth in this Article XV in respect of any Senior
Indebtedness at any time held by it, to the same extent as any other holder of
Senior Indebtedness, and nothing in this Indenture shall deprive the Trustee of
any of its rights as such holder.

                  With respect to the holders of Senior Indebtedness of the
Company, the Trustee undertakes to perform or to observe only such of its
covenants and obligations as are specifically set forth in this Article XV, and
no implied covenants or obligations with respect to the holders of such Senior
Indebtedness shall be read into this Indenture against the Trustee. The Trustee
shall not be deemed to owe any fiduciary duty to the holders of such Senior
Indebtedness and, subject to the provisions of Article VI of this Indenture, the
Trustee shall not be liable to any holder of such Senior Indebtedness if it
shall pay over or deliver to Securityholders, the Company or any other Person
money or assets to which any holder of such Senior Indebtedness shall be
entitled by virtue of this Article XV or otherwise.

                  Nothing in this Article XV shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 6.06.

                  SECTION 15.08.  Subordination May Not Be Impaired.

                  No right of any present or future holder of any Senior
Indebtedness of the Company to enforce subordination as herein provided shall at
any time in any way be prejudiced or impaired by any act or failure to act on
the part of the Company or by any act or failure to act, in good faith, by any
such holder, or by any noncompliance by the Company with the terms, provisions
and covenants of this Indenture, regardless of any knowledge thereof that any
such holder may have or otherwise be charged with.

                  Without in any way limiting the generality of the foregoing
paragraph, the holders of Senior Indebtedness of the Company may, at any time
and from time to time, without the consent of or notice to the Trustee or the
Securityholders, without incurring responsibility to the Securityholders and
without impairing or releasing the subordination provided in this Article XV or
the obligations hereunder of the holders of the Securities to the holders of
such Senior Indebtedness, do any one or more of the following: (i) change the
manner, place or terms of payment or extend the time of payment of, or renew or
alter, such Senior Indebtedness, or otherwise amend or supplement in any manner
such Senior Indebtedness or any instrument evidencing the same or any agreement
under which such Senior Indebtedness is outstanding; (ii) sell, exchange,
release or otherwise deal with any property pledged, mortgaged or otherwise
securing such Senior Indebtedness; (iii) release any Person liable in any manner
for the collection of such Senior Indebtedness; and (iv) exercise or refrain
from exercising any rights against the Company and any other Person.


                                  ARTICLE XVI.
                      EXTENSION OF INTEREST PAYMENT PERIOD

                  SECTION 16.01.  Extension of Interest Payment Period.

                  (a) So long as no Event of Default has occurred and is
continuing, the Company shall have the right, at any time and from time to time
during the term of the Securities, to defer payments of interest by extending
the interest payment period of such Securities for a period not exceeding 10


                                      100

<PAGE>


consecutive semi-annual periods, including the first such semi-annual period
during such extension period (the "Extended Interest Payment Period"), during
which Extended Interest Payment Period no interest shall be due and payable;
provided that no Extended Interest Payment Period may extend beyond the Maturity
Date. To the extent permitted by applicable law, interest, the payment of which
has been deferred because of the extension of the interest payment period
pursuant to this Section 16.01, will bear interest thereon at the Coupon Rate
compounded semi-annually for each semi-annual period of the Extended Interest
Payment Period ("Compounded Interest"). At the end of the Extended Interest
Payment Period, the Company shall pay all interest accrued and unpaid on the
Securities, including any Additional Sums and Compounded Interest (together,
"Deferred Interest") that shall be payable to the holders of the Securities in
whose names the Securities are registered in the Security Register on the first
record date after the end of the Extended Interest Payment Period.

         (b) Before the termination of any Extended Interest Payment Period, the
Company may further defer payments of interest by further extending such period,
provided that such period, together with all such previous and further
extensions within such Extended Interest Payment Period, shall not exceed 10
consecutive semi-annual periods, including the first such semi-annual period
during such Extended Interest Payment Period, or extend beyond the Maturity Date
of the Securities. Upon the termination of any Extended Interest Payment Period
and the payment of all Deferred Interest then due, the Company may elect to
commence a new Extended Interest Payment Period, subject to the foregoing
requirements. No interest shall be due and payable during an Extended Interest
Payment Period, except at the end thereof, but the Company may prepay at any
time all or any portion of the interest accrued during an Extended Interest
Payment Period.

<PAGE>


                  SECTION 16.02.  Notice of Extension.

                  (a) If the Property Trustee is the only registered holder of
the Securities at the time the Company selects an Extended Interest Payment
Period, the Company shall give written notice to the Administrative Trustees,
the Property Trustee and the Trustee of its selection of such Extended Interest
Payment Period at least five Business Days before the earlier of (i) the next
succeeding date on which distributions on the Trust Securities issued by Markel
Capital Trust would have been payable except for such election, or (ii) the date
the Administrative Trustees are required to give notice of the record date, or
the date such Distributions are payable, to any national securities exchange or
to holders of the Capital Securities issued by Markel Capital Trust, but in any
event at least five Business Days before such record date.

                  (b) If the Property Trustee is not the only holder of the
Securities at the time the Company selects an Extended Interest Payment Period,
the Company shall give the holders of the Securities and the Trustee written
notice of its selection of such Extended Interest Payment Period at least 10
Business Days before the earlier of (i) the next succeeding Interest Payment
Date, or (ii) the date the Company is required to give notice of the record or
payment date of such interest payment to any national securities exchange.

                  (c) The semi-annual period in which any notice is given
pursuant to paragraphs (a) or (b) of this Section 16.02 shall be counted as one
of the 10 semi-annual periods permitted in the maximum Extended Interest Payment
Period permitted under Section 16.01. There is no limitation on the number of
times that the Company may elect to begin an Extended Interest Payment Period.

                  The Chase Manhattan Bank hereby accepts the trusts in this
Indenture declared and provided, upon the terms and conditions hereinabove set
forth.

                               MARKEL CORPORATION
        8.71% SERIES _ JUNIOR SUBORDINATED DEFERRABLE INTEREST DEBENTURE
                              DUE JANUARY 1, 2046

                  Markel Corporation, a Virginia corporation (the "Company",
which term includes any successor Person under the Indenture hereinafter
referred to), for value received, hereby promises to pay to __________, or
registered assigns, the principal sum of $__________ Dollars on January 1, 2046,
or on such earlier date as the Company shall determine pursuant to Section 14.06
of the Indenture (the "Maturity Date"), unless previously prepaid, and to pay
interest on the outstanding principal amount hereof from January 13, 1997, or
from the most recent interest payment date (each such date, an "Interest Payment
Date") to which interest has been paid or duly provided for, semi-annually
(subject to deferral as set forth herein) in arrears on January 1 and July 1 of
each year, commencing July 1, 1997, at the rate of 8.71% per annum until the
principal hereof shall have become due and payable, and on any overdue principal
and premium, if any, and (without duplication and to the extent that payment of
such interest is enforceable under applicable law) on any overdue installment of
interest at the same rate per annum compounded semi-annually. The amount of
interest payable on any Interest Payment Date shall be computed on the basis of
a 360-day year of twelve 30-day months and, for any period less than a full
calendar month, the number of days elapsed in such month. In the event that any
date on which the principal of (or premium, if any) or interest on this Security
is payable is not a Business Day, then payment payable on such date will be made
on the next succeeding day that is a Business Day (and without any interest or
other payment in respect of any such delay), with the same force and effect as
if made on such date.

                  The interest installment so payable, and punctually paid or
duly provided for, on any Interest Payment Date will, as provided in the
Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities, as defined in said Indenture) is registered at the close
of business on the regular record date for such interest installment, which
shall be the date fifteen days prior to the relevant Interest Payment Date. Any



                                      106

<PAGE>



such interest installment not punctually paid or duly provided for shall
forthwith cease to be payable to the holders on such regular record date and may
be paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on a special record date to
be fixed by the Trustee for the payment of such defaulted interest, notice
whereof shall be given to the holders of Securities not less than 10 days prior
to such special record date, or may be paid at any time in any other lawful
manner not inconsistent with the requirements of any securities exchange on
which the Securities may be listed, and upon such notice as may be required by
such exchange, all as more fully provided in the Indenture.

                  The principal of (and premium, if any) and interest on this
Security shall be payable at the office or agency of the Trustee in New York,
New York maintained for that purpose in any coin or currency of the United
States of America that at the time of payment is legal tender for payment of
public and private debts; provided, however, that, payment of interest may be
made at the option of the Company by (i) check mailed to the holder at such
address as shall appear in the Security Register or (ii) by transfer to an
account maintained by the Person entitled thereto, provided that proper written
transfer instructions have been received by the relevant record date; provided
that if this Security is in global form, the interest hereon shall be made in
immediately available funds. Notwithstanding the foregoing, so long as the
Holder of this Security is the Property Trustee, the payment of the principal of
(and premium, if any) and interest on this Security will be made at such place
and to such account as may be designated by the Property Trustee.

                  The indebtedness evidenced by this Security is, to the extent
provided in the Indenture, subordinate and junior in right of payment to the
prior payment in full of Senior Indebtedness, and this Security is issued

obligations, duties and immunities thereunder of the Trustee, the Company and

have the right to prepay this Security in whole (but not in part) at the Special
Event Prepayment Price. "Special Event Prepayment Price" shall mean an amount in

Optional Prepayment Price with respect to an optional prepayment of such
Securities on the Initial Optional Prepayment Date, together with scheduled
payments of interest on the Securities from the prepayment date to and including
the Initial Optional Prepayment Date discounted to the prepayment date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months)
at the Adjusted Treasury Rate, plus, in each case, any accrued and unpaid
interest thereon, including Compounded Interest and Additional Sums, if any, to
the date of such prepayment.

                  In addition, the Company shall have the right to prepay this
Security, in whole or in part, at any time on or after the Initial Optional
Prepayment Date (an "Optional Prepayment"), at the Optional Prepayment Prices
set forth below (expressed as percentages of the principal amount to be prepaid)
plus accrued and unpaid interest thereon (including Additional Sums and

                           2017 and thereafter ......... 100.000%

                  The Optional Prepayment Price or the Special Event Prepayment
Price, as the case requires, shall be paid prior to 12:00 noon, New York City
time, on the date of such prepayment, provided, that the Company shall deposit
with the Trustee an amount sufficient to pay the applicable Prepayment Price by
10:00 a.m., New York City time, on the date such Prepayment Price is to be paid.
Any prepayment pursuant to this paragraph will be made upon not less than 30
days nor more than 60 days notice. If the Securities are only partially prepaid
by the Company pursuant to an Optional Prepayment, the Securities will be
prepaid pro rata or by lot or by any other method utilized by the Trustee
provided that if at the time of prepayment, the Securities are registered as a
Global Security, the Depositary shall determine in accordance with its
procedures the principal amount of Securities held for the account of its
participants to be prepaid.

                  In the event of prepayment of this Security in part only, a
new Security or Securities for the unprepaid portion hereof will be issued in
the name of the holder hereof upon the cancellation hereof.

                  If a Tax Event occurs, then the Company will have the right
(i) prior to the termination of Markel Capital Trust, to advance the Maturity
Date of this Security to the minimum extent required, but not to a date earlier
than twenty years from January 13, 1997 (the "Issue Date"), or (ii) to terminate

                                      111

<PAGE>


Markel Capital Trust (if not previously terminated) and advance the Maturity
Date of this Security to the minimum extent required, but not to a date earlier
than forty years from the Issue Date, in each case such that, in the written
opinion of counsel experienced in such matters delivered to the Company, after
advancing the Maturity Date, interest paid on the Securities shall be deductible
for federal income tax purposes.

                  In case an Event of Default, as defined in the Indenture,
shall have occurred and be continuing, the principal of all of the Securities
may be declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Indenture.

                  The Indenture contains provisions permitting the Company and
the Trustee, with the consent of the holders of a majority in aggregate
principal amount of the Securities at the time outstanding, as defined in the
Indenture, to execute supplemental indentures for the purpose of adding any
provisions to or changing in any manner or eliminating any of the provisions of
the Indenture or of modifying in any manner the rights of the holders of the
Securities; provided, however, that no such supplemental indenture shall,
without the consent of each holder of Securities then outstanding and affected
thereby, (i) extend the Maturity Date of any Securities, or reduce the principal
amount thereof, or reduce any amount payable on prepayment thereof, or reduce
the rate or extend the time of payment of interest thereon (subject to Article
XVI of the Indenture), or make the principal of, or interest or premium on, the
Securities payable in any coin or currency other than U.S. dollars, or impair or
affect the right of any holder of Securities to institute suit for the payment
thereof, or (ii) reduce the aforesaid percentage of Securities, the holders of
which are required to consent to any such supplemental indenture. The Indenture
also contains provisions permitting the holders of a majority in aggregate
principal amount of the Securities at the time outstanding affected thereby, on
behalf of all of the holders of the Securities, to waive any past default in the
performance of any of the covenants contained in the Indenture, or established
pursuant to the Indenture, and its consequences, except a default in the payment


                                      112

<PAGE>

of the principal of or premium, if any, or interest on any of the Securities or
a default in respect of any covenant or provision under which the Indenture
cannot be modified or amended without the consent of each holder of Securities
then outstanding. Any such consent or waiver by the holder of this Security
(unless revoked as provided in the Indenture) shall be conclusive and binding
upon such holder and upon all future holders and owners of this Security and of
any Security issued in exchange heretofore or in place hereof (whether by
registration of transfer or otherwise), irrespective of whether or not any
notation of such consent or waiver is made upon this Security.

                  No reference herein to the Indenture and no provision of this
Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of and
premium, if any, and interest on this Security at the time and place and at the
rate and in the money herein prescribed.

                  The Company shall have the right, at any time and from time to
time during the term of the Securities, to defer payments of interest by
extending the interest payment period of such Securities for a period not
exceeding 10 consecutive semi-annual periods, including the first such
semi-annual period during such extension period, and not to extend beyond the
Maturity Date of the Securities (an "Extended Interest Payment Period"), at the
end of which period the Company shall pay all interest then accrued and unpaid
together with interest thereon at the rate specified for the Securities (to the
extent that payment of such interest is enforceable under applicable law).
Before the termination of any such Extended Interest Payment Period, the Company
may further defer payments of interest by further extending such Extended
Interest Payment Period, provided that such Extended Interest Payment Period,
together with all such previous and further extensions within such Extended
Interest Payment Period, shall not exceed 10 consecutive semi-annual periods,
including the first semi-annual period during such Extended Interest Payment
Period, or extend beyond the Maturity Date of the Securities. Upon the
termination of any such Extended Interest Payment Period and the payment of all
accrued and unpaid interest and any additional amounts then due, the Company may
commence a new Extended Interest Payment Period, subject to the foregoing
requirements.

<PAGE>


                  The Company has agreed that it will not (i) declare or pay any
dividends or distributions on, or redeem, purchase, acquire, or make a
liquidation payment with respect to, any of the Company's capital stock (which
includes common and preferred stock) or (ii) make any payment of principal,
interest or-premium, if any, on or repay or repurchase or redeem any debt
securities of the Company that rank pari passu with or junior in right of
payment to the Securities or make any guarantee payments with respect to any
guarantee by the Company of the debt securities or any Subsidiary of the Company
if such guarantee ranks pari passu or junior in right of payment to the
Securities (other than (a) dividends or distributions in shares of, or options,
warrants or rights to subscribe for or purchase shares of, Common Stock of the
Company, (b) any declaration of a dividend in connection with the implementation
of a stockholder's 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 Company's capital stock or the exchange or the
conversion of one class or series of the Company's capital stock for another
class or series of the Company's capital stock, (e) the purchase of fractional
interests in shares of the Company's capital stock pursuant to the exchange or
conversion of such capital stock or the security being exchanged or converted,
and (f) purchases or issuances of Common Stock in connection with any of the
Company's stock option, stock purchase, stock loan or other benefit plans for
its directors, officers or employees or any of the Company's dividend
reinvestment plans, in each case as now existing or hereinafter established or
amended) if at such time (i) there shall have occurred any event of which the
Company 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 Company shall not have taken reasonable steps to cure, (ii) if such
Securities are held by Markel Capital Trust, the Company shall be in default
with respect to its payment of any obligations under the Capital Securities
Guarantee or (iii) the Company shall have given notice of its election of the
exercise of its right to extend the interest payment period and any such
extension shall be continuing.

                  The Company will have the right at any time to liquidate
Markel Capital Trust and cause the Securities to be distributed to the holders
of the Trust Securities in liquidation of Markel Capital Trust.

                  The Securities are issuable only in registered form without
coupons in denominations of $1,000 and any integral multiple thereof. As
provided in the Indenture and subject to the transfer restrictions limitations
as may be contained herein and therein from time to time, the transfer of this
Security is registrable by the holder hereof on the Security Register of the
Company, upon surrender of this Security for registration of transfer at the
office or agency of the Trustee in the City and State of New York accompanied by
a written instrument or instruments of transfer in form satisfactory to the
Company or the Trustee duly executed by the holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of authorized
denominations and for the same aggregate principal amount and series will be
issued to the designated transferee or transferees. No service charge will be
made for any such registration of transfer, but the Company may require payment
of a sum sufficient to cover any tax or other governmental charge payable in
relation thereto.

                  Prior to due presentment for registration of transfer of this
Security, the Company, the Trustee, any paying agent and the registrar may deem
and treat the registered holder hereof as the absolute owner hereof (whether or
not this Security shall be overdue and notwithstanding any notice of ownership
or writing hereon made by anyone other than the Security Registrar) for the
purpose of receiving payment of or on account of the principal hereof and
premium, if any, and interest due hereon and for all other purposes, and neither
the Company nor the Trustee nor any paying agent nor any registrar shall be
affected by any notice to the contrary.

                  No recourse shall be had for the payment of the principal of
or premium, if any, or interest on this Security, or for any claim based hereon,
or otherwise in respect hereof, or based on or in respect of the Indenture,
against any incorporator, stockholder, officer or director, past, present or
future, as such, of the Company or of any predecessor or successor Person,
whether by virtue of any constitution, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability being,
by the acceptance hereof and as part of the consideration for the issuance
hereof, expressly waived and released.

                  All terms used in this Security that are defined in the
Indenture shall have the meanings assigned to them in the Indenture.

                  THE INDENTURE AND THE SECURITIES SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO
CONFLICT OF LAW PROVISIONS THEREOF.

                                       OF
                             MARKEL CAPITAL TRUST I

         THIS  DECLARATION OF TRUST is made as of December 30, 1996 (this "Trust

sponsor (the "Sponsor"),  and Chase Manhattan Bank Delaware,  a Delaware banking
corporation,  as trustee  (the  "Trustee").  The Sponsor and the Trustee  hereby

the  contemplated  operation of the Trust created hereby and the issuance of the

defined). Prior to the execution and delivery of such amended and restated Trust
Agreement  or  Declaration,  the Trustee  shall not have any duty or  obligation
hereunder or with respect of the trust estate,  except as otherwise  required by
applicable  law or as may be  necessary to obtain  prior to such  execution  and
delivery any  licenses,  consents or  approvals  required by  applicable  law or
otherwise.  Notwithstanding  the  foregoing,  the  Trustee  may take all actions
deemed proper as are necessary to effect the transactions contemplated herein.

         4. The Sponsor,  as sponsor of the Trust, is hereby authorized,  in its
discretion,  (i) to prepare and  distribute  one or more  offering  memoranda in
preliminary  and final form,  including any  necessary or desirable  amendments,
relating  to the  offering  and sale of  Capital  Securities  of the  Trust in a

1933,  as amended  (the "1933  Act"),  and such other forms or filings as may be
required by the 1933 Act, the  Securities  Exchange Act of 1934, as amended,  or
the Trust  Indenture  Act of 1939,  as  amended,  in each case  relating  to the

execute  on behalf of the  Trust,  such  applications,  reports,  surety  bonds,
irrevocable consents,  appointments of attorney for service of process and other
papers and  documents  that shall be  necessary  or  desirable  to  register  or
establish the exemption from registration of the Capital Securities of the Trust
under the securities or "Blue Sky" laws of such jurisdictions as the Sponsor, on
behalf of the Trust, may deem necessary or desirable; (iii) to


                                      -1-

execute  and  file an  application,  and  all  other  applications,  statements,
certificates,  agreements  and other  instruments  that  shall be  necessary  or
desirable to cause the Capital Securities to be listed on the Private Offerings,
Resales and Trading through Automated Linkages  ("PORTAL") Market,  with PORTAL,
and, if and at such time as determined  by the Sponsor,  with the New York Stock
Exchange or any other national stock exchange or the Nasdaq  National Market for
listing or quotation of the Capital Securities of the Trust; (iv) to execute and
deliver  letters or documents to, or  instruments  for filing with, a depository
relating to the Capital  Securities  of the Trust;  (v) to execute,  deliver and
perform on behalf of the Trust one or more underwriting or purchase  agreements,
registration rights agreements,  dealer manager  agreements,  escrow agreements,
subscription agreements and other similar or related agreements providing for or
relating to the sale of the Capital Securities of the Trust; and (vi) to execute
on behalf of the Trust any and all documents,  papers and  instruments as may be
desirable in connection with any of the foregoing.

         In the event that any filing  referred to in this Section 4 is required
by the rules and  regulations of the Commission,  PORTAL or state  securities or
Blue Sky laws to be executed on behalf of the Trust by a Trustee, the Trustee or
any trustee of the Trust appointed pursuant to Section 6 hereof, in its capacity
as trustee of the Trust,  is hereby  authorized and directed to join in any such
filing and to execute  on behalf of the Trust any and all of the  foregoing,  it
being  understood that any such trustee of the Trust, in its capacity as trustee
of the Trust,  shall not be  required  to join in any such  filing or execute on
behalf  of the  Trust  any  such  document  unless  required  by the  rules  and
regulations of the Commission, PORTAL or state securities or Blue Sky laws.

         5. This Trust Agreement may be executed in one or more counterparts.

         6. The  number  of  trustees  of the Trust  initially  shall be one and
thereafter  the number of trustees of the Trust shall be such number as shall be
fixed from time to time by a written  instrument signed by the Sponsor which may
increase  or  decrease  (but not below one) the number of trustees of the Trust;
provided,  however,  that to the extent  required by the Business Trust Act, one
trustee of the Trust shall  either be a natural  person who is a resident of the
State of Delaware or, if not a natural person, an entity which has its principal
place of  business  in the State of  Delaware.  Subject  to the  foregoing,  the
Sponsor is entitled to appoint or remove  without cause any trustee of the Trust
at any time.  Any trustee of the Trust may resign upon thirty days' prior notice
to the Sponsor.

         7.  This  Trust  Agreement  shall be  governed  by,  and  construed  in
accordance  with, the laws of the State of Delaware  (without regard to conflict
of laws principles).

         Default under the Declaration shall also not be waivable; or

been cured for every purpose of this Declaration, but no such waiver shall
extend to any subsequent or other Default or Event of Default with respect to
the Common Securities or impair any right consequent thereon.

Securities to acquire the Debentures, and (c) except as otherwise limited
herein, to engage in only those other activities necessary, advisable or

proceeds derived from investments, mortgage or pledge any of its assets, or
otherwise undertake (or permit to be undertaken) any activity that would cause
the Trust not to be classified for United States federal income tax purposes as
a grantor trust.

                         (a) invest any proceeds received by the Trust from
         holding the Debentures, but shall distribute all such proceeds to
         Holders of Securities pursuant to the terms of this Declaration and of
         the Securities;

                                       22

<PAGE>

                         (b) acquire any assets other than as expressly provided
         herein;

                         (c) possess Trust property for other than a Trust
         purpose;

                         (d) make any loans or incur any indebtedness other than

         beneficial ownership of, or beneficial interest in, the Trust other

         I, (A) direct the time, method and place of conducting any proceeding
         with respect to any remedy available to the Debenture Trustee, or
         exercising any trust or power conferred upon the Debenture Trustee with
         respect to the Debentures, (B) waive any past default that is waivable

         of the Indenture or the Debentures where such consent shall be required
         unless the Trust shall have received an opinion of a nationally
         recognized independent tax counsel experienced in such matters to the
         effect that such amendment, modification or termination will not cause
         more than an insubstantial risk that, for United States federal income
         tax purposes, the Trust will not be classified as a grantor trust.

SECTION 3.8       Powers and Duties of the Property Trustee.

                  (a) The legal title to the Debentures shall be owned by and
held of record in the name of the Property Trustee in trust for the benefit of
the Holders of the Securities. The right, title and interest of the Property
Trustee to the Debentures shall vest automatically in each Person who may
hereafter be appointed as Property Trustee in accordance with Section 5.7. Such

                                       23

<PAGE>


vesting and cessation of title shall be effective whether or not conveyancing
documents with regard to the Debentures have been executed and delivered.

                  (b) The Property Trustee shall not transfer its right, title
and interest in the Debentures to the Administrative Trustees or to the Delaware
Trustee (if the Property Trustee does not also act as Delaware Trustee).

                  (c) The Property Trustee shall:

                         (i) establish and maintain a segregated non-interest
         bearing trust account (the "Property Trustee Account") in the name of
         and under the exclusive control of the Property Trustee on behalf of
         the Holders of the Securities and, upon the receipt of payments of
         funds made in respect of the Debentures held by the Property Trustee,
         deposit such funds into the Property Trustee Account and make, or cause
         any Paying Agent to make, payments to the Holders of the Capital
         Securities and Holders of the Common Securities from the Property
         Trustee Account in accordance with Section 6.1. Funds in the Property
         Trustee Account shall be held uninvested until disbursed in accordance
         with this Declaration. The Property Trustee Account shall be an account
         that is maintained with a banking institution the rating on whose
         long-term unsecured indebtedness is at least equal to the rating
         assigned to the Capital Securities by a "nationally recognized
         statistical rating organization", as that term is defined for purposes
         of Rule 436(g)(2) under the Securities Act;

                        (ii) engage in such ministerial activities as shall be
         necessary or appropriate to effect the redemption of the Capital
         Securities and the Common Securities to the extent the Debentures are
         redeemed or mature; and

                       (iii) upon written notice of distribution issued by the
         Administrative Trustees in accordance with the terms of the Securities,
         engage in such ministerial activities as shall be necessary or
         appropriate to effect the distribution of the Debentures to Holders of
         Securities upon the occurrence of certain events.

                  (d) The Property Trustee shall take all actions and perform
such duties as may be specifically required of the Property Trustee pursuant to
the terms of this Declaration and the Securities.

                  (e) Subject to Section 3.9(a), the Property Trustee shall take
any Legal Action which arises out of or in connection with an Event of Default
of which a Responsible Officer of the Property Trustee has actual knowledge or
the Property Trustee's duties and obligations under this Declaration or the
Trust Indenture Act and if the Property Trustee shall have failed to take such
Legal Action, the Holders of the Capital Securities may take such Legal Action,
to the same extent as if such Holders of Capital Securities held an aggregate
principal amount of Debentures equal to the aggregate Liquidation Amount of such
Capital Securities, without first proceeding against the Property Trustee or the
Trust; provided, however, that if an Event of Default has occurred and is
continuing and such event is attributable to the failure of the Debenture Issuer
to pay the principal of or premium, if any, or interest on the Debentures on the
date such principal, premium, if any, or interest is otherwise payable (or in
the case of redemption, on the redemption date), then a Holder of Capital
Securities may directly institute a proceeding for enforcement of payment to
such Holder of the principal of or premium, if any, or interest on the
Debentures having a principal amount equal to the aggregate Liquidation Amount
of the Capital Securities of such Holder (a "Direct Action") on or after the
respective due date specified in the Debentures. In connection with such Direct
Action, the rights of the Holders of the Common Securities will be subrogated to
the rights of such Holder of Capital Securities to the extent of any payment
made by the Debenture Issuer to such Holder of Capital Securities in such Direct
Action. Except as provided in the preceding sentences, the Holders of Capital
Securities will not be able to exercise directly any other remedy available to
the holders of the Debentures.

                  (f) The Property Trustee shall continue to serve as a Trustee
until either:

                         (i) the Trust has been completely liquidated and the
         proceeds of the liquidation distributed to the Holders of Securities
         pursuant to the terms of the Securities; or


                                       25

<PAGE>


                        (ii) a Successor Property Trustee has been appointed and
         has accepted that appointment in accordance with Section 5.7(b).

                  (g) The Property Trustee shall have the legal power to
exercise all of the rights, powers and privileges of a holder of Debentures
under the Indenture and, if an Event of Default actually known to a Responsible
Officer of the Property Trustee occurs and is continuing, the Property Trustee
shall, for the benefit of Holders of the Securities, enforce its rights as
holder of the Debentures subject to the rights of the Holders pursuant to this
Declaration and the terms of the Securities.

                  (h) The Property Trustee shall be authorized to undertake any
actions set forth in ss.317(a) of the Trust Indenture Act.

                  (i) For such time as the Property Trustee is the Paying Agent,
the Property Trustee may authorize one or more Persons to act as additional
Paying Agents and to pay Distributions, redemption payments or liquidation
payments on behalf of the Trust with respect to all securities and any such
Paying Agent shall comply with ss.317(b) of the Trust Indenture Act. Any such
additional Paying Agent may be removed by the Property Trustee at any time the
Property Trustee remains as Paying Agent and a successor Paying Agent or
additional Paying Agents may be (but are not required to be) appointed at any
time by the Property Trustee.

                  (j) Subject to this Section 3.8, the Property Trustee shall
have none of the duties, liabilities, powers or the authority of the
Administrative Trustees set forth in Section 3.6.

                  The Property Trustee must exercise the powers set forth in
this Section 3.8 in a manner that is consistent with the purposes and functions
of the Trust set out in Section 3.3, and the Property Trustee shall not take any
action that is inconsistent with the purposes and functions of the Trust set out
in Section 3.3.

SECTION 3.9       Certain Duties and Responsibilities of the Property Trustee.

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

                  (b) No provision of this Declaration shall be construed to
relieve the Property Trustee from liability for its own negligent action, its
own negligent failure to act, or its own willful misconduct, except that:

                         (i) prior to the occurrence of an 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 Property
                  Trustee shall be determined solely by the express provisions
                  of this Declaration and in the Securities and the Property
                  Trustee shall not be liable except for the performance of such
                  duties and obligations as are specifically set forth in this
                  Declaration and in the Securities, and no implied covenants or
                  obligations shall be read into this Declaration against the
                  Property Trustee; and

                           (B) in the absence of bad faith on the part of the
                  Property Trustee, the Property 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 Property Trustee and conforming to the
                  requirements of this Declaration; provided, however, that in
                  the case of any such certificates or opinions that by any
                  provision hereof are specifically required to be furnished to
                  the Property Trustee, the Property Trustee shall be under a
                  duty to examine the same to determine whether or not they
                  conform to the requirements of this Declaration;


                                       27

<PAGE>



                        (ii) the Property Trustee shall not be liable for any
         error of judgment made in good faith by a Responsible Officer of the
         Property Trustee, unless it shall be proved that the Property Trustee
         was negligent in ascertaining the pertinent facts;

                       (iii) the Property 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 not less than a
         Majority in Liquidation Amount of the Securities relating to the time,
         method and place of conducting any proceeding for any remedy available
         to the Property Trustee, or exercising any trust or power conferred
         upon the Property Trustee under this Declaration;

                        (iv) no provision of this Declaration shall require the
         Property 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 it 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
         Declaration or indemnity reasonably satisfactory to the Property
         Trustee against such risk or liability is not reasonably assured to it;

                         (v) the Property Trustee's sole duty with respect to
         the custody, safe keeping and physical preservation of the Debentures
         and the Property Trustee Account shall be to deal with such property in
         a similar manner as the Property Trustee deals with similar property
         for its own account, subject to the protections and limitations on
         liability afforded to the Property Trustee under this Declaration and
         the Trust Indenture Act;

                        (vi) the Property Trustee shall have no duty or
         liability for or with respect to the value, genuineness, existence or
         sufficiency of the Debentures or the payment of any taxes or
         assessments levied thereon or in connection therewith;

         action hereunder, the Property Trustee (i) may request instructions
         from the Holders of the Securities which instructions may only be given

         within the discretion or rights or powers conferred upon it by this
         Declaration.

                  (b) No provision of this Declaration shall be deemed to impose

jurisdiction in which it shall be illegal, or in which the Property Trustee

majority of the Administrative Trustees and without the consent of the Holders
of the Securities, the Delaware Trustee or the Property Trustee, merge or
convert with or into, consolidate, amalgamate, or be replaced by, or convey,
transfer or lease its properties and assets as an entirety or substantially as
an entirety to, a trust organized as such under the laws of any State; provided
that:

                         (i) such successor entity (the "Successor Entity")
         either:

                           (A) expressly assumes all of the obligations of the
                  Trust under the Securities; or


                                       33

<PAGE>

                           (B) substitutes for the Securities other securities
                  having substantially the same terms as the Securities (the

                  Distributions and payments upon liquidation, redemption and
                  otherwise;

                        (ii) the Sponsor expressly appoints a trustee of the
         Successor Entity that possesses the same powers and duties as the
         Property Trustee as the holder of the Debentures;

         if any;

                        (iv) such merger, conversion, consolidation,
         amalgamation, replacement, conveyance, transfer or lease does not cause
         the Capital Securities (including any Successor Securities) to be

         organization;

                         (v) such merger, conversion, consolidation,
         amalgamation, replacement, conveyance, transfer or lease does not
         adversely affect the rights, preferences and privileges of the Holders
         of the Securities (including any Successor Securities) in any material
         respect (other than with respect to any dilution of such Holders'
         interests in the new entity);

                        (vi) such Successor Entity has a purpose identical to
         that of the Trust;

                       (vii) prior to such merger, conversion, consolidation,
         amalgamation, replacement, conveyance, transfer or lease, the Sponsor
         has received an opinion of an independent counsel to the Trust
         experienced in such matters to the effect that:

                           (A) such merger, conversion, consolidation,
                  amalgamation, replacement, conveyance, transfer or lease does

<PAGE>

                  not adversely affect the rights, preferences and privileges of
                  the Holders of the Securities (including any Successor
                  Securities) in any material respect (other than with respect
                  to any dilution of the Holders' interest in the new entity);

                           (B) following such merger, conversion, consolidation,
                  amalgamation, replacement, conveyance, transfer or lease,
                  neither the Trust nor the Successor Entity will be required to
                  register as an Investment Company under the Investment Company
                  Act; and

                           (C) following such merger, conversion, consolidation,
                  amalgamation, replacement, conveyance, transfer, or lease, the
                  Trust (or the Successor Entity) will continue to be classified
                  as a grantor trust for United States federal income tax
                  purposes; and

                      (viii) the Sponsor or any permitted successor or assignee
         owns all of the common securities of such Successor Entity and
         guarantees the obligations of such Successor Entity under the Successor
         Securities at least to the extent provided by the Capital Securities
         Guarantee and the Common Securities Guarantee.

                  (c) Notwithstanding Section 3.15(b), the Trust shall not,
except with the consent of all Holders of the Securities in liquidation amount
of the Securities, consolidate, amalgamate, merge or convert with or into, or be
replaced by, or convey, transfer or lease its properties and assets as an
entirety or substantially as an entirety to, any other Person or permit any
other Person to consolidate, amalgamate, merge or convert with or into, or
replace it if such consolidation, amalgamation, merger, conversion, replacement,
conveyance, transfer or lease would cause the Trust or the Successor Entity not
to be classified as a grantor trust for United States federal income tax
purposes.

                  At the Closing Time, the Sponsor will purchase all of the

                  The Sponsor acknowledges the rights of the Holders of Capital

or principal on the Debentures, to institute Direct Actions against the
Debenture Issuer for enforcement of its payment obligations on the Debentures.

                                   ARTICLE V

meets the applicable requirements. Notwithstanding the above, unless an Event of
Default shall have occurred and be continuing, at any time or times, for the
purpose of meeting the legal requirements of the Trust Indenture Act or of any
jurisdiction in which any part of the Trust's property may at the time be
located, the Holders of a Majority in Liquidation Amount of the Common
Securities acting as a class at a meeting of the Holders of the Common
Securities, and the Administrative Trustees shall have power to appoint one or
more Persons either to act as a co-trustee, jointly with the Property Trustee,

such property, in either case with such powers as may be provided in the
instrument of appointment, and to vest in such person or persons in such

Delaware; or

                  (b) if not a natural person, an entity which has its principal
place of business in the State of Delaware, and otherwise meets the requirements
of applicable law, provided that, if the Property Trustee has its principal

capacity as Property Trustee.

         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 5.3(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.

                  (b) If at any time the Property Trustee shall cease to be
eligible to so act under Section 5.3(a), the Property Trustee shall immediately

the obligor referred to in ss.310(b) of the Trust Indenture Act) shall in all
respects comply with the provisions of ss. 310(b) of the Trust Indenture Act.

                  (c) A Trustee appointed to office shall hold office until his
successor shall have been appointed or until his death, removal or resignation.
Any Trustee may resign from office (without need for prior or subsequent
accounting) by an instrument in writing signed by the Trustee and delivered to
the Sponsor and the Trust, which resignation shall take effect upon such
delivery or upon such later date as is specified therein; provided, however,
that:

                         (i) No such resignation of the Trustee that acts as the
         Property Trustee shall be effective:

                           (A) until a Successor Property Trustee has been
                  appointed and has accepted such appointment by instrument
                  executed by such Successor Property Trustee and delivered to
                  the Administrative Trustees, the Sponsor and the resigning
                  Property Trustee; or

                           (B) until the assets of the Trust have been
                  completely liquidated and the proceeds thereof distributed to
                  the Holders of the Securities; and

                        (ii) no such resignation of the Trustee that acts as the
         Delaware Trustee shall be effective until a Successor Delaware Trustee
         has been appointed and has accepted such appointment by instrument
         executed by such Successor Delaware Trustee and delivered to the
         Administrative Trustees, the Sponsor and the resigning Delaware
         Trustee.

                  (d) The Holders of the Common Securities shall use their best
efforts to promptly appoint a Successor Delaware Trustee or Successor Property
Trustee, as the case may be, if the Property Trustee or the Delaware Trustee
delivers an instrument of resignation in accordance with this Section 5.7.

                  (e) If no Successor Property Trustee or Successor Delaware
Trustee shall have been appointed and accepted appointment as provided in this
Section 5.7 within 60 days after delivery of an instrument of resignation or
removal, the Property Trustee or Delaware Trustee resigning or being removed, as
applicable, may petition any court of competent jurisdiction for appointment of
a Successor Property Trustee or Successor Delaware Trustee. Such court may
thereupon, after prescribing such notice, if any, as it may deem proper and
prescribe, appoint a Successor Property Trustee or Successor Delaware Trustee,
as the case may be.


                                       43

<PAGE>


                  (f) No Property Trustee or Delaware Trustee shall be liable
for the acts or omissions of any Successor Property Trustee or Successor
Delaware Trustee, as the case may be.

SECTION 5.8       Vacancies Among Trustees.

                  If a Trustee ceases to hold office for any reason and the
number of Trustees is not reduced pursuant to Section 5.1, or if the number of
Trustees is increased pursuant to Section 5.1, a vacancy shall occur. A
resolution certifying the existence of such vacancy by the Administrative
Trustees or, if there are more than two, a majority of the Administrative
Trustees, shall be conclusive evidence of the existence of such vacancy. The
vacancy shall be filled with a Trustee appointed in accordance with Section 5.7.

SECTION 5.9       Effect of Vacancies.

                  The death, resignation, retirement, removal, bankruptcy,
dissolution, liquidation, incompetence or incapacity to perform the duties of a
Trustee shall not operate to annul the Trust. Whenever a vacancy in the number
of Administrative Trustees shall occur, until such vacancy is filled by the
appointment of an Administrative Trustee in accordance with Section 5.7, the
Administrative Trustees in office, regardless of their number, shall have all
the powers granted to the Administrative Trustees and shall discharge all the
duties imposed upon the Administrative Trustees by this Declaration.

SECTION 5.10      Meetings.

                  If there is more than one Administrative Trustee, meetings of
the Administrative Trustees shall be held from time to time upon the call of any
Administrative Trustee. Regular meetings of the Administrative Trustees may be
held at a time and place fixed by resolution of the Administrative Trustees.
Notice of any in-person meetings of the Administrative Trustees shall be hand
delivered or otherwise delivered in writing (including by facsimile, with a hard
copy by overnight courier) not less than 24 hours before such meeting. Notice of
any telephonic meetings of the Administrative Trustees or any committee thereof
shall be hand delivered or otherwise delivered in writing (including by
facsimile, with a hard copy by overnight courier) not less than 24 hours before


                                       44

<PAGE>


a meeting. Notices shall contain a brief statement of the time, place and
anticipated purposes of the meeting. The presence (whether in person or by
telephone) of an Administrative Trustee at a meeting shall constitute a waiver
of notice of such meeting except where an Administrative Trustee attends a
meeting for the express purpose of objecting to the transaction of any activity
on the ground that the meeting has not been lawfully called or convened. Unless
provided otherwise in this Declaration, any action of the Administrative
Trustees may be taken at a meeting by vote of a majority of the Administrative
Trustees present (whether in person or by telephone) and eligible to vote with
respect to such matter, provided that a Quorum is present, or without a meeting
by the written consent of the Administrative Trustees. In the event there is
only one Administrative Trustee, any and all action of such Administrative
Trustee shall be evidenced by a written consent of such Administrative Trustee.

SECTION 5.11      Delegation of Power.

                  (a) Any Administrative Trustee may, by power of attorney
consistent with applicable law, delegate to any other natural person over the
age of 21 his or her power for the purpose of executing any documents
contemplated in Section 3.6, including any registration statement or amendment
thereto filed with the Commission, or making any other governmental filing; and

                  (b) The Administrative Trustees shall have power to delegate
from time to time to such of their number or to officers of the Trust the doing
of such things and the execution of such instruments either in the name of the
Trust or the names of the Administrative Trustees or otherwise as the
Administrative Trustees may deem expedient, to the extent such delegation is not
prohibited by applicable law or contrary to the provisions of the Trust, as set
forth herein.

Section 5.12      Merger, Conversion, Consolidation or Succession to Business.

                  Any corporation into which the Property Trustee or the
Delaware Trustee or any Administrative Trustee that is not a natural person, as
the case may be, may be merged or converted or with which it may be
consolidated, or any corporation resulting from any merger, conversion or
consolidation to which such Trustee shall be a party, or any corporation
succeeding to all or substantially all the corporate trust business of such
Trustee, shall be the successor of such Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto.

                                   ARTICLE VI
                                 DISTRIBUTIONS

SECTION 6.1       Distributions.

                  Each Holder shall receive Distributions in accordance with the
applicable terms of such Holder's Securities. If and to the extent that the
Debenture Issuer makes a payment of interest (including Compounded Interest (as
defined in the Indenture) and Additional Sums (as defined in the Indenture)),
premium and/or principal or any other payments on the Debentures held by the
Property Trustee or Liquidated Damages (as defined in the Registration Rights
Agreement) or any other payments pursuant to the Registration Rights Agreement
with respect to the Debentures held by the Property Trustee (the amount of any
such payment being a "Payment Amount"), the Property Trustee shall and is
directed, to the extent funds are available for that purpose, to make a
distribution (a "Distribution") of the Payment Amount to Holders in accordance
with the respective terms of the Securities held by them.

                                  ARTICLE VII
                             ISSUANCE OF SECURITIES

SECTION 7.1       General Provisions Regarding Securities.

                  (a) The Administrative Trustees shall on behalf of the Trust
issue one class of capital securities representing undivided beneficial
interests in the assets of the Trust having such terms as are set forth in Annex
I (the "Series A Capital Securities") and one class of common securities

                                       46

<PAGE>


representing undivided beneficial interests in the assets of the Trust having
such terms as are set forth in Annex I (the "Common Securities"). The
Administrative Trustees shall on behalf of the Trust issue one class of capital
securities representing undivided beneficial interests in the Trust having such
terms as set forth in Annex I (the "Series B Capital Securities") in exchange
for Series A Capital Securities accepted for exchange in the Exchange Offer,
which Series B Capital Securities shall not bear the legends required by Section
9.2(i) unless the Holder of such Series A Capital Securities is either (A) a
broker-dealer who purchased such Series A Capital Securities directly from the
Trust for resale pursuant to Rule 144A or any other available exemption under
the Securities Act, (B) a Person participating in the distribution of the Series
A Capital Securities or (C) a Person who is an affiliate (as defined in Rule
144A) of the Trust. The Trust shall issue no securities or other interests in
the assets of the Trust other than the Capital Securities and the Common
Securities.

                  (b) The consideration received by the Trust for the issuance
of the Securities shall constitute a contribution to the capital of the Trust
and shall not constitute a loan to the Trust.

                  (c) Upon issuance of the Securities as provided in this
Declaration, the Securities so issued shall be deemed to be validly issued,
fully paid and non-assessable.

                  (d) Every Person, by virtue of having become a Holder or a
Capital Security Beneficial Owner in accordance with the terms of this
Declaration, shall be deemed to have expressly assented and agreed to the terms
of, and shall be bound by, this Declaration.

SECTION 7.2       Execution and Authentication.

                           The Securities shall be signed on behalf of the Trust
by an Administrative Trustee. Such signature may be by manual or facsimile
signature. Typographical and other minor errors or defects in any reproduction
of any such signature shall not affect the validity of any Security. In case any
Administrative Trustee who shall have signed any of the Securities shall cease
to be such Administrative Trustee before the Securities so signed shall be

                                       47

<PAGE>


delivered by the Trust, such Securities nevertheless may be delivered as though
the Person who signed such Securities had not ceased to be such Administrative
Trustee; and any Securities may be signed on behalf of the Trust by such Persons
who, at the actual date of execution of such Security, shall be the
Administrative Trustees of the Trust, although at the date of the execution and
delivery of the Declaration any such Person was not such an Administrative
Trustee.

                  A Capital Security shall not be valid until authenticated by
the manual signature of an authorized officer of the Property Trustee. The
signature shall be conclusive evidence that the Capital Security has been
authenticated under this Declaration.

                  Upon a written order of the Trust signed by one Administrative
Trustee, the Property Trustee shall authenticate the Capital Securities for
original issue. The aggregate number of Capital Securities outstanding at any
time shall not exceed the number set forth in the Terms in Annex I hereto except
as provided in Section 7.6.

                  The Property Trustee may appoint an authenticating agent
acceptable to the Trust to authenticate Capital Securities. An authenticating
agent may authenticate Capital Securities whenever the Property Trustee may do
so. Each reference in this Declaration to authentication by the Property Trustee
includes authentication by such agent. An authenticating agent has the same
rights as the Property Trustee to deal with the Sponsor or an Affiliate.

SECTION 7.3       Form and Dating.

                  The Capital Securities and the Property Trustee's certificate
of authentication shall be substantially in the form of Exhibit A-1 and the
Common Securities shall be substantially in the form of Exhibit A-2, each of
which is hereby incorporated in and expressly made a part of this Declaration.
Certificates representing the Securities may be printed, lithographed or
engraved or may be produced in any other manner as is reasonably acceptable to
the Administrative Trustees, as evidenced by their execution thereof. The
Securities may have letters, CUSIP or other numbers, notations or other marks of

                                       48

<PAGE>


identification or designation and such legends or endorsements required by law,
stock exchange rule, agreements to which the Trust is subject, if any, or usage
(provided that any such notation, legend or endorsement is in a form acceptable
to the Administration Trustees, as evidenced by their execution thereof). The
Trust at the direction of the Sponsor shall furnish any such legend not
contained in Exhibit A-1 to the Property Trustee in writing. Each Capital
Security shall be dated the date of its authentication. The terms and provisions
of the Securities set forth in Annex I and the forms of Securities set forth in
Exhibits A-1 and A-2 are part of the terms of this Declaration and to the extent
applicable, the Property Trustee and the Sponsor, by their execution and
delivery of this Declaration, expressly agree to such terms and provisions and
to be bound thereby.

                  (a) Global Securities.  The Capital Securities offered and
sold to QIBs in reliance on Rule 144A or offered and sold outside the United
States to non-U.S. persons in offshore transactions in reliance on Regulation S,
as provided in the Purchase Agreement, shall be issued in the form of one or
more, permanent global Securities in definitive, fully registered form without
Distribution coupons with the appropriate global legends and the Restricted
Securities Legend set forth in Exhibit A-1 hereto (respectively, a "Rule 144A
Global Capital Security" or "Regulation S Global Capital Security"), which shall
be deposited on behalf of the purchasers of the Capital Securities represented
thereby with the Property Trustee or the Registrar, as custodian for the
Clearing Agency, and registered in the name of the Clearing Agency or a nominee
of the Clearing Agency, duly executed by the Trust and authenticated by the
Property Trustee as hereinafter provided. The number of Capital Securities
represented by the Rule 144A Global Capital Security and the Regulation S Global
Capital Security may from time to time be increased or decreased by adjustments
made on the records of the Property Trustee and the Clearing Agency or its
nominee as hereinafter provided.

                  (b) Book-Entry Provisions. This Section 7.3(b) shall apply
only to the Rule 144A Global Capital Securities, the Regulation S Global Capital
Securities and such other Capital Securities in global form as may be authorized
by the Trust to be deposited with or on behalf of the Clearing Agency.


                                       49

<PAGE>


                  The Administrative Trustees shall execute and the Property
Trustee shall, in accordance with this Section 7.3, authenticate and make
available for delivery initially one or more Rule 144A Global Capital Securities
and one or more Regulation S Global Capital Securities that (i) shall be
registered in the name of Cede & Co. or other nominee of such Clearing Agency
and (ii) shall be delivered by the Trustee to such Clearing Agency or pursuant
to such Clearing Agency's written instructions or held by the Property Trustee
or the Registrar as custodian for the Clearing Agency.

                  Members of, or participants in, the Clearing Agency
("Participants") shall have no rights under this Declaration with respect to any
Rule 144A Global Capital Security or any Regulation S Global Capital Security
held on their behalf by the Clearing Agency or by the Property Trustee or the
Registrar as the custodian of the Clearing Agency or under such Rule 144A Global
Capital Security or such Regulation S Global Capital Security, and the Clearing
Agency may be treated by the Trust, the Property Trustee and any agent of the
Trust or the Property Trustee as the absolute owner of such Rule 144A Global
Capital Security or such Regulation S Global Capital Security for all purposes
whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the
Trust, the Property Trustee or any agent of the Trust or the Property Trustee
from giving effect to any written certification, proxy or other authorization
furnished by the Clearing Agency or impair, as between the Clearing Agency and
its Participants, the operation of customary practices of such Clearing Agency
governing the exercise of the rights of a holder of a beneficial interest in any
Rule 144A Global Capital Security or any Regulation S Global Capital Security.

                  (c) Definitive Capital Securities. Except as provided in
Section 7.9, owners of beneficial interests in a Rule 144A Global Capital
Security or a Regulation S Global Capital Security will not be entitled to
receive physical delivery of certificated Capital Securities ("Definitive
Capital Securities"). Purchasers of Securities who are "accredited investors"
(as defined in Rule 501(a)(1), (2), (3) or (7) under the Securities Act) and did
not purchase Capital Securities in reliance on Regulation S will receive Capital

                                       50

<PAGE>

Securities in the form of individual certificates in definitive, fully
registered form without distribution coupons and with the Restricted Securities
Legend set forth in Exhibit A-1 hereto ("Restricted Definitive Capital
Securities"); provided, however, that upon registration of transfer of such
Restricted Definitive Capital Securities to a QIB, such Restricted Definitive
Capital Securities will, unless the Rule 144A Global Capital Security has
previously been exchanged, be exchanged for an interest in a Rule 144A Global
Capital Security pursuant to the provisions of Section 9.2. Restricted
Definitive Capital Securities will bear the Restricted Securities Legend set
forth on Exhibit A-1 unless removed in accordance with this Section 7.3 or
Section 9.2.

SECTION 7.4       Registrar, Paying Agent and Exchange Agent.

                  The Trust shall maintain in the Borough of Manhattan, The City
of New York, (i) an office or agency where Capital Securities may be presented
for registration of transfer ("Registrar"), (ii) an office or agency where
Capital Securities may be presented for payment ("Paying Agent") and (iii) an
office or agency where Securities may be presented for exchange ("Exchange
Agent"). The Registrar shall keep a register of the Capital Securities and of
their transfer. The Trust may appoint the Registrar, the Paying Agent and the
Exchange Agent and may appoint one or more co-registrars, one or more additional
paying agents and one or more additional exchange agents in such other locations
as it shall determine. The term "Registrar" includes any additional registrar,
"Paying Agent" includes any additional paying agent and the term "Exchange
Agent" includes any additional exchange agent. The Trust may change any Paying
Agent, Registrar, co-registrar or Exchange Agent without prior notice to any
Holder. The Paying Agent shall be permitted to resign as Paying Agent upon 30
days' written notice to the Property Trustee and the Sponsor. The Trust shall
notify the Property Trustee of the name and address of any Agent not a party to
this Declaration. If the Trust fails to appoint or maintain another entity as
Registrar, Paying Agent or Exchange Agent, the Property Trustee shall act as
such. The Trust or any of its Affiliates may act as Paying Agent, Registrar, or
Exchange Agent. The Property Trustee shall act as Paying Agent, Registrar and
Exchange Agent for the Common Securities.


                                       51

<PAGE>


                  The Trust initially appoints the Property Trustee as
Registrar, Paying Agent, and Exchange Agent for the Capital Securities.

SECTION 7.5       Paying Agent to Hold Money in Trust.

                  The Trust shall require each Paying Agent other than the
Property Trustee to agree in writing that the Paying Agent will hold in trust
for the benefit of Holders or the Property Trustee all money held by the Paying
Agent for the payment of Liquidation Amounts or Distributions on the Securities,
and will notify the Property Trustee if there are insufficient funds for such
purpose. While any such insufficiency continues, the Property Trustee may
require a Paying Agent to pay all money held by it to the Property Trustee. The
Trust at any time may require a Paying Agent to pay all money held by it to the
Property Trustee and to account for any money disbursed by it. Upon payment over
to the Property Trustee the Paying Agent (if other than the Trust or an
Affiliate of the Trust) shall have no further liability for the money. If the
Trust or the Sponsor or an Affiliate of the Trust or the Sponsor acts as Paying
Agent, it shall segregate and hold in a separate trust fund for the benefit of
the Holders all money held by it as Paying Agent.

SECTION 7.6       Replacement Securities.

                  If the Holder of a Security claims that the Security has been
lost, destroyed or wrongfully taken or if such Security is mutilated and is
surrendered to the Trust or in the case of the Capital Securities to the
Property Trustee, the Administrative Trustees shall execute and the Property
Trustee shall authenticate a replacement Security if the Property Trustee's and
the Administrative Trustees' requirements, as the case may be, are met. An
indemnity bond must be provided by the Holder which, in the judgment of the
Property Trustee, is sufficient to protect the Trustees, the Sponsor or any
authenticating agent from any loss which any of them may suffer if a Security is
replaced. The Trust may charge such Holder for its expenses in replacing a
Security.

                  Every replacement Security is an additional beneficial
interest in the Trust.

SECTION 7.7       Outstanding Capital Securities.

                  The Capital Securities outstanding at any time are all the
Capital Securities authenticated by the Property Trustee except for those
cancelled by it, those delivered to it for cancellation, and those described in
this Section as not outstanding.

                  If a Capital Security is replaced, paid or purchased pursuant
to Section 7.6 hereof, it ceases to be outstanding unless the Property Trustee
receives proof satisfactory to it that the replaced, paid or purchased Capital
Security is held by a bona fide purchaser.

                  If Capital Securities are considered paid in accordance with
the terms of this Declaration, they cease to be outstanding and Distributions on
them shall cease to accumulate.

                  Except as otherwise provided herein, a Capital Security does
not cease to be outstanding because one of the Trustees, the Sponsor or an
Affiliate of the Sponsor holds the Security.

SECTION 7.8       Capital Securities in Treasury.

                  In determining whether the Holders of the required amount of
Securities have concurred in any direction, waiver or consent, Capital
Securities owned by the Trust, the Sponsor or an Affiliate of the Sponsor, as
the case may be, shall be disregarded and deemed not to be outstanding, except
that for the purposes of determining whether the Property Trustee shall be fully
protected in relying on any such direction, waiver or consent, only Capital
Securities which a Responsible Officer of the Property Trustee actually knows
are so owned shall be so disregarded.

SECTION 7.9       Temporary Securities.

                  (a) Until Definitive Securities are ready for delivery, the
Trust may prepare and, in the case of the Capital Securities, the Property
Trustee shall authenticate temporary Securities. Temporary Securities shall be
substantially in the form of Definitive Securities but may have variations that
the Trust considers appropriate for temporary Securities. Without unreasonable

                                       53

<PAGE>


delay, the Trust shall prepare and, in the case of the Capital Securities, the
Property Trustee shall authenticate Definitive Securities in exchange for
temporary Securities.

                  (b) A Global Capital Security deposited with the Clearing
Agency or with the Property Trustee as custodian for the Clearing Agency
pursuant to Section 7.3 shall be transferred to the beneficial owners thereof in
the form of certificated Capital Securities only if such transfer complies with
Section 9.2 and (i) the Clearing Agency notifies the Company that it is
unwilling or unable to continue as Clearing Agency for such Global Capital
Security or if at any time such Clearing Agency ceases to be a "clearing agency"
registered under the Exchange Act and a clearing agency is not appointed by the
Sponsor within 90 days of such notice, (ii) a Default or an Event of Default has
occurred and is continuing or (iii) the Trust at its sole discretion elects to
cause the issuance of certificated Capital Securities.

                  (c) Any Global Capital Security that is transferable to the
beneficial owners thereof in the form of certificated Capital Securities
pursuant to this Section 7.9 shall be surrendered by the Clearing Agency to the
Property Trustee located in the Borough of Manhattan, The City of New York, to
be so transferred, in whole or from time to time in part, without charge, and
the Property Trustee shall authenticate and make available for delivery, upon
such transfer of each portion of such Global Capital Security, an equal
aggregate Liquidation Amount of Securities of authorized denominations in the
form of certificated Capital Securities. Any portion of a Global Capital
Security transferred pursuant to this Section shall be registered in such names
as the Clearing Agency shall direct. Any Capital Security in the form of
certificated Capital Securities delivered in exchange for an interest in the
Restricted Global Capital Security shall, except as otherwise provided by
Sections 7.3 and 9.1, bear the Restricted Securities Legend set forth in Exhibit
A-1 hereto.

                  (d) Subject to the provisions of Section 7.9(c), the Holder of
a Global Capital Security may grant proxies and otherwise authorize any Person,
including Participants and Persons that may hold interests through Participants,
to take any action which such Holder is entitled to take under this Declaration
or the Securities.

<PAGE>


                  (e) In the event of the occurrence of any of the events
specified in Section 7.9(b), the Trust will promptly make available to the
Property Trustee a reasonable supply of certificated Capital Securities in fully
registered form without Distribution coupons.

SECTION 7.10      Cancellation.

                  The Trust at any time may deliver Capital Securities to the
Property Trustee for cancellation. The Registrar, Paying Agent and Exchange
Agent shall forward to the Property Trustee any Capital Securities surrendered
to them for registration of transfer, redemption, exchange or payment. The
Property Trustee shall promptly cancel all Capital Securities surrendered for
registration of transfer, redemption, exchange, payment, replacement or
cancellation and shall dispose of canceled Capital Securities in accordance with
its customary procedures unless any Administrative Trustee otherwise directs the
Property Trustee in writing. The Trust may not issue new Capital Securities to
replace Capital Securities that it has paid or that have been delivered to the
Property Trustee for cancellation or that any Holder has exchanged.

SECTION 7.11      CUSIP Numbers.

                  The Trust in issuing the Capital Securities may use "CUSIP"
numbers (if then generally in use), and, if so, the Property Trustee shall use
"CUSIP" numbers in notices of redemption as a convenience to Holders of Capital
Securities; provided that any such notice may state that no representation is
made as to the correctness of such numbers either as printed on the Capital
Securities or as contained in any notice of a redemption and that reliance may
be placed only on the other identification numbers printed on the Capital
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Sponsor will promptly notify the Property Trustee
of any change in the CUSIP numbers.

                              TERMINATION OF TRUST

SECTION 8.1       Termination of Trust.

         (a)      The Trust shall automatically be terminated and dissolved and
its affairs wound up upon the earliest to occur of the following events:

                         (i) upon the bankruptcy of the Sponsor;

                        (ii) upon the filing of a certificate of dissolution or
         liquidation or its equivalent with respect to the Sponsor, or the
         revocation of the Sponsor's charter and the expiration of 90 days after
         the date of revocation without a reinstatement thereof;

                       (iii) following the distribution of a Like Amount of the
         Debentures to the Holders of the Securities, provided that, the
         Property Trustee has received written notice from the Sponsor directing
         the Property Trustee to terminate the Trust (which direction is
         optional, and except as otherwise expressly provided below, within the
         discretion of the Sponsor) and provided, further, that such direction
         and such distribution is conditioned on the Administrative Trustees'
         receipt of an opinion of an independent tax counsel experienced in such
         matters (a "No Recognition Opinion"), which opinion may rely on
         published rulings of the Internal Revenue Service, to the effect that
         the Holders of the Securities will not recognize any gain or loss for
         United States federal income tax purposes as a result of the
         dissolution of the Trust and the distribution of the Debentures;

                        (iv) upon the entry of a decree of judicial dissolution
         of the Trust by a court of competent jurisdiction;

                         (v) when all of the Securities shall have been called
         for redemption and the amounts necessary for redemption thereof shall
         have been paid to the Holders in accordance with the terms of the
         Securities; or


                                       56

<PAGE>


                        (vi) the expiration of the term of the Trust provided in
         Section 3.14.

                  (b) As soon as is practicable after the occurrence of an event
referred to in Section 8.1(a) and the completion of the winding up of the Trust
and after satisfaction of all liabilities of the Trust, the Administrative
Trustees shall file a certificate of cancellation with the Secretary of State of
the State of Delaware.

                  (c) The provisions of Section 3.9 and Article X shall survive
the termination of the Trust.

                                   ARTICLE IX
                              TRANSFER OF INTERESTS

SECTION 9.1       Transfer of Securities.

                  (a) Securities may only be transferred, in whole or in part,
in accordance with the terms and conditions set forth in this Declaration and in
the terms of the Securities. Any transfer or purported transfer of any Security
not made in accordance with this Declaration shall be null and void.

                  (b) Subject to this Article IX, Capital Securities may only be
transferred, in whole or in part, in accordance with the terms and conditions
set forth in this Declaration. Any transfer or purported transfer of any
Security not made in accordance with this Declaration shall be null and void.

                  (c) Subject to Section 3.15, the Sponsor and any Related Party
may only transfer the Common Securities to the Sponsor or a Related Party after
the delivery to the Property Trustee of an Officers' Certificate certifying that
the transferee is either the Sponsor or a Related Party.

                  (d) The Property Trustee shall provide for the registration of
Securities and of the transfer of Securities, which will be effected without
charge but only upon payment (with such indemnity as the Property Trustee may
require) in respect of any tax or other governmental charges that may be imposed
in relation to it. Upon surrender for registration of transfer of any
Securities, the Administrative Trustees shall execute and the


                                       57

<PAGE>



Property Trustee shall cause one or more new Securities to be issued in the name
of the designated transferee or transferees. Every Security surrendered for
registration of transfer shall be accompanied by a written instrument of
transfer in form satisfactory to the Property Trustee duly executed by the
Holder or such Holder's attorney duly authorized in writing. Each Security
surrendered for registration of transfer shall be delivered to the Property
Trustee and canceled in accordance with Section 7.10. A transferee of a Security
shall be entitled to the rights and subject to the obligations of a Holder
hereunder upon the receipt by such transferee of a Security. By acceptance of a
Security, each transferee shall be deemed to have agreed to be bound by this
Declaration.

SECTION 9.2       Transfer Procedures and Restrictions.

                  (a) General. Except as otherwise provided in Section 9.2(b),
if Capital Securities are issued upon the registration of transfer, exchange or
replacement of Capital Securities bearing the Restricted Securities Legend set
forth in Exhibit A-1 hereto, or if a request is made to remove such Restricted
Securities Legend on Capital Securities, the Capital Securities so issued shall
bear the Restricted Securities Legend, or the Restricted Securities Legend shall
not be removed, as the case may be, unless there is delivered to the Sponsor and
the Property Trustee such satisfactory evidence, which shall include an Opinion
of Counsel licensed to practice law in the State of New York, as may be
reasonably required by the Sponsor and the Property Trustee, that neither the
legend nor the restrictions on transfer set forth therein are required to ensure
that transfers thereof are made pursuant to an exception from the registration
requirements of the Securities Act or, with respect to Restricted Securities,
that such Securities are not "restricted" within the meaning of Rule 144. Upon
provision of such satisfactory evidence, the Property Trustee, at the written
direction of the Sponsor, shall authenticate and deliver Capital Securities that
do not bear the legend.

                  (b) Transfers After Effectiveness of a Registration Statement.
After the effectiveness of a Registration Statement with respect to any Capital
Securities, all requirements pertaining to legends on such Capital Securities
will cease to apply, and beneficial interests in a Capital Security in global

                                       58

<PAGE>


form without legends will be available to transferees of such Capital
Securities, upon exchange of the transferring Holder's Restricted Definitive
Capital Security or directions to transfer such Holder's beneficial interest in
the Rule 144A Global Capital Security or the Regulation S Global Capital
Security, as the case may be. No such transfer or exchange of a Restricted
Definitive Capital Security or of an interest in the Rule 144A Global Capital
Security or the Regulation S Global Capital Security shall be effective unless
the transferor delivers to the Property Trustee a certificate in a form
substantially similar to that attached hereto as the "Form of Assignment" in
Exhibit A-1. Except as otherwise provided in Section 9.2(m), after the
effectiveness of a Registration Statement, the Trust shall issue and the
Property Trustee, upon a written order of the Trust signed by one Administrative
Trustee, shall authenticate a Capital Security in global form without the
Restricted Securities Legend (the "Unrestricted Global Capital Security") to
deposit with the Clearing Agency to evidence transfers of beneficial interests
from the (i) Rule 144A Global Capital Security or the Regulation S Global
Capital Security and (ii) Restricted Definitive Capital Securities.

                  (c) Transfer and Exchange of Definitive Capital Securities.
When Definitive Capital Securities are presented to the Registrar or
co-Registrar:

                  (x) to register the transfer of such Definitive Capital
         Securities, or

                  (y) to exchange such Definitive Capital Securities which
         became mutilated, destroyed, defaced, stolen or lost, for an equal
         number of Definitive Capital Securities,

the Registrar or co-Registrar shall register the transfer or make the exchange
as requested if its reasonable requirements for such transaction are met;
provided, however, that the Definitive Capital Securities surrendered for
registration of transfer or exchange:

                         (i) shall be duly endorsed or accompanied by a written
         instrument of transfer in form reasonably satisfactory to the Trust and
         the Registrar or co-Registrar, duly executed by the Holder thereof or
         his attorney duly authorized in writing; and


                                       59

<PAGE>


                        (ii) in the case of Definitive Capital Securities that
         are Restricted Definitive Capital Securities:

                           (A) if such Restricted Capital Securities are being
                  delivered to the Registrar by a Holder for registration in the
                  name of such Holder, without transfer, a certification from
                  such Holder to that effect; or

                           (B) if such Restricted Capital Securities are being
                  transferred: (i) a certification from the transferor in a form
                  substantially similar to that attached hereto as the "Form of
                  Assignment" in Exhibit A-1, and (ii) if the Trust or the
                  Registrar so requests, evidence reasonably satisfactory to
                  them as to the compliance with the restrictions set forth in
                  the Restricted Securities Legend.

                  (d) Restrictions on Transfer of a Definitive Capital Security
for a Beneficial Interest in a Global Capital Security. A Definitive Capital
Security may not be exchanged for a beneficial interest in a Global Capital
Security except upon satisfaction of the requirements set forth below. Upon
receipt by the Property Trustee of a Definitive Capital Security, duly endorsed
or accompanied by appropriate instruments of transfer, in form satisfactory to
the Property Trustee, together with:

                         (i) if such Definitive Capital Security is a Restricted
         Capital Security, certification from the transferor in a form
         substantially similar to that attached hereto as the "Form of
         Assignment" in Exhibit A-1; provided, however, that such Definitive
         Capital Security may only be exchanged for an interest in a Regulation
         S Global Security where such Definitive Capital Security is being
         transferred pursuant to Regulation S or Rule 144 (if available); and

                        (ii) whether or not such Definitive Capital Security is
         a Restricted Capital Security, written instructions directing the
         Property Trustee to make, or to direct the Clearing Agency to make, an
         adjustment on its books and records with respect to the appropriate


                                       60

<PAGE>


         Global Capital Security to reflect an increase in the number of the
         Capital Securities represented by such Global Capital Security,

then the Property Trustee shall cancel such Definitive Capital Security and
cause, or direct the Clearing Agency to cause, the aggregate number of Capital
Securities represented by the appropriate Global Capital Security to be
increased accordingly. If no Global Capital Securities are then outstanding, the
Trust shall issue and the Property Trustee shall authenticate, upon written
order of any Administrative Trustee, an appropriate number of Capital Securities
in global form.

                  (e) Transfer and Exchange of Global Capital Securities.
Subject to Section 9.2(f), the transfer and exchange of Global Capital
Securities or beneficial interests therein shall be effected through the
Clearing Agency, in accordance with this Declaration (including applicable
restrictions on transfer set forth herein, if any) and the procedures of the
Clearing Agency therefor.

                  (f) Transfer of a Beneficial Interest in a Global Capital
Security for a Definitive Capital Security.

                         (i) Any Person having a beneficial interest in a Global
         Capital Security may upon request, but only upon 20 days prior notice
         to the Property Trustee, and if accompanied by the information
         specified below, exchange such beneficial interest for a Definitive
         Capital Security representing the same number of Capital Securities.
         Upon receipt by the Property Trustee from the Clearing Agency or its
         nominee on behalf of any Person having a beneficial interest in a
         Global Capital Security of written instructions or such other form of
         instructions as is customary for the Clearing Agency or the Person
         designated by the Clearing Agency as having such a beneficial interest
         in a Restricted Capital Security and a certification from the
         transferor (in a form substantially similar to that attached hereto as
         the "Form of Assignment" in Exhibit A-1), which may be submitted by
         facsimile, then the Property Trustee will cause the aggregate number of
         Capital Securities represented by Global Capital Securities to be


                                       61

<PAGE>


         reduced on its books and records and, following such reduction, the
         Trust will execute and the Property Trustee will authenticate and make
         available for delivery to the transferee a Definitive Capital Security;

                        (ii) Definitive Capital Securities issued in exchange
         for a beneficial interest in a Global Capital Security pursuant to this
         Section 9.2(f) shall be registered in such names and in such authorized
         denominations as the Clearing Agency, pursuant to instructions from its
         Participants or indirect participants or otherwise, shall instruct the
         Property Trustee in writing. The Property Trustee shall deliver such
         Capital Securities to the Persons in whose names such Capital
         Securities are so registered in accordance with such instructions of
         the Clearing Agency.

                  (g) Restrictions on Transfer and Exchange of Global Capital
Securities. Notwithstanding any other provisions of this Declaration (other than
the provisions set forth in subsection (h) of this Section 9.2), a Global
Capital Security may not be transferred as a whole except by the Clearing Agency
to a nominee of the Clearing Agency or another nominee of the Clearing Agency or
by the Clearing Agency or any such nominee to a successor Clearing Agency or a
nominee of such successor Clearing Agency.

                  Prior to the expiration of the restricted period, as
contemplated by Regulation S, beneficial interests in the Regulation S Global
Capital Security may be exchanged for beneficial interests in the Rule 144A
Global Capital Security only if such exchange occurs in connection with a
transfer of the Capital Securities pursuant to Rule 144A and the transferor
first delivers to the Property Trustee a written certificate (in a form
substantially similar to that attached hereto as the "Form of Assignment" in
Exhibit A-1) to the effect that the Capital Securities are being transferred to
a person who the transferor reasonably believes is a QIB, purchasing for its own
account or the account of a QIB in a transaction meeting the requirements of
Rule 144A and in accordance with all applicable securities laws of the states of
the United States and other jurisdictions.

                  Beneficial interests in the Rule 144A Global Capital Security
may be transferred to a person who takes delivery in the form of an interest in
the Regulation S Global Capital Security, whether before or after the expiration


                                       62

<PAGE>


of such restricted period, as contemplated by Regulation S, only if the
transferor first delivers to the Property Trustee a written certificate (in a
form substantially similar to that attached hereto as the "Form of Assignments"
in Exhibit A-1) to the effect that such transfer is being made in accordance
with Rule 903 or 904 of Regulation S or Rule 144 (if available) and that, if
such transfer occurs prior to the expiration of such restricted period, the
interest transferred will be held immediately thereafter through Euroclear or
CEDEL.

                  (h) Authentication of Definitive Capital Securities. If at any
time Global Capital Securities are outstanding:

                         (i) there occurs a Default or an Event of Default which
         is continuing, or

                        (ii) the Trust, in its sole discretion, notifies the
         Property Trustee in writing that it elects to cause the issuance of
         Definitive Capital Securities under this Declaration,

then the Trust will execute, and the Property Trustee, upon receipt of a written
order of the Trust signed by one Administrative Trustee requesting the
authentication and delivery of Definitive Capital Securities to the Persons
designated by the Trust, will authenticate and make available for delivery
Definitive Capital Securities, equal in number to the number of Capital
Securities represented by the Global Capital Securities, in exchange for such
Global Capital Securities.

                  (i) Legend.

                         (i) Except as permitted by the following paragraph
         (ii), each Capital Security certificate evidencing the Global Capital
         Securities and the Definitive Capital Securities (and all Capital
         Securities issued in exchange therefor or substitution thereof) shall
         bear a legend (the "Restricted Securities Legend") in substantially the
         following form:


                                       63

                 THE CAPITAL SECURITIES REPRESENTED HEREBY HAVE NOT BEEN
                 REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE
                 "SECURITIES ACT") OR ANY STATE SECURITIES LAWS OR ANY OTHER
                 APPLICABLE SECURITIES LAW. NEITHER THIS CAPITAL SECURITY NOR
                 ANY INTEREST OR PARTICIPATION HEREIN MAY BE REOFFERED, SOLD,
                 ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE
                 DISPOSED OF IN THE ABSENCE OF SUCH REGISTRATION OR UNLESS SUCH
                 TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, SUCH
                 REGISTRATION.

                 THE HOLDER OF THIS CAPITAL SECURITY BY ITS ACCEPTANCE HEREOF
                 AGREES TO OFFER, SELL OR OTHERWISE TRANSFER THIS CAPITAL
                 SECURITY, PRIOR TO THE DATE (THE "RESALE RESTRICTION
                 TERMINATION DATE") WHICH IS THREE YEARS AFTER THE LATER OF THE
                 ORIGINAL ISSUANCE DATE HEREOF AND THE LAST DATE ON WHICH THE
                 COMPANY OR ANY AFFILIATE OF THE COMPANY WAS THE OWNER OF THIS

                 STATEMENT WHICH HAS BEEN DECLARED EFFECTIVE UNDER THE

                 ACT ("RULE 144A"), TO A PERSON IT REASONABLY BELIEVES IS A

         Global Capital Security) pursuant to an effective registration
         statement under the Securities Act or pursuant to Rule 144 under the
         Securities Act after such registration statement ceases to be
         effective:

                           (A) in the case of any Restricted Capital Security
                  that is a Definitive Capital Security, the Registrar shall
                  permit the Holder thereof to exchange such Restricted Capital
                  Security for a Definitive Capital Security that does not bear

         of any tax or other governmental charge that may be imposed in relation
         to it.

                       (iii) The Registrar or co-registrar shall not be required

         Participant thereof, with respect to any ownership interest in the

         Security). The rights of beneficial owners in any Global Capital
         Security shall be exercised only through the Clearing Agency subject to
         the applicable rules and procedures of the Clearing Agency. The
         Property Trustee may conclusively rely and shall be fully protected in
         relying upon information furnished by the Clearing Agency or any agent
         thereof with respect to its Participants and any beneficial owners.

                        (ii) The Property Trustee and Registrar shall have no
         obligation or duty to monitor, determine or inquire as to compliance
         with any restrictions on transfer imposed under this Declaration or
         under applicable law with respect to any transfer of any interest in
         any Capital Security (including any transfers between or among Clearing
         Agency Participants or beneficial owners in any Global Capital
         Security) other than to require delivery of such certificates and other
         documentation or evidence as are expressly required by, and to do so if

outstanding Series A Capital Securities shall have been properly tendered and
not withdrawn, the Property Trustee shall make an endorsement on the Global
Capital Security for Series A Capital Securities indicating the reduction in the
number and aggregate liquidation amount represented thereby as a result of the
Exchange Offer.

                  The Trust shall deliver such Definitive Capital Securities for

other claim to or interest in such Security on the part of any Person, whether
or not the Trustees shall have actual or other notice thereof.

the Capital Security Beneficial Owners pursuant to Section 9.2:

or consents hereunder) as the Holder of the Capital Securities and the sole
holder of the Global Certificates and shall have no obligation to the Capital
Security Beneficial Owners;

                  (c) to the extent that the provisions of this Section 9.4

be exercised only through the Clearing Agency and shall be limited to those
established by law and agreements between such Capital Security Beneficial

SECTION 10.1      Liability.

                  (a) Except as expressly set forth in this Declaration, the
Securities Guarantees and the terms of the Securities, the Sponsor shall not be:

                         (i) personally liable for the return of any portion of
         the capital contributions (or any return thereon) of the Holders of the
         Securities which shall be made solely from assets of the Trust; and

                        (ii) be required to pay to the Trust or to any Holder of
         Securities any deficit upon dissolution of the Trust or otherwise.

                  (b) The Sponsor shall be liable for all of the fees, expenses,

to the extent not satisfied out of the Trust's assets.

                  (c) Pursuant to ss. 3803(a) of the Business Trust Act, the
Holders of the Capital Securities shall be entitled to the same limitation of

organized under the General Corporation Law of the State of Delaware.

                  (a) No Indemnified Person shall be liable, responsible or
accountable in damages or otherwise to the Trust 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 on behalf of the Trust and in a
manner such Indemnified Person reasonably believed to be within the scope of the
authority conferred on such Indemnified Person by this Declaration or by law,

<PAGE>


                  (b) An Indemnified Person shall be fully protected in relying
in good faith upon the records of the Trust and upon such information, opinions,
reports or statements presented to the Trust by any Person as to matters the
Indemnified Person reasonably believes are within such other Person's
professional or expert competence and who has been selected with reasonable care
by or on behalf of the Trust, including information, opinions, reports or
statements as to the value and amount of the assets, liabilities, profits,
losses, or any other facts pertinent to the existence and amount of assets from
which Distributions to Holders of Securities might properly be paid.

SECTION 10.3      Fiduciary Duty.

                  (a) To the extent that, at law or in equity, an Indemnified
Person has duties (including fiduciary duties) and liabilities relating thereto
to the Trust or to any other Covered Person, an Indemnified Person acting under
this Declaration shall not be liable to the Trust or to any other Covered Person
for its good faith reliance on the provisions of this Declaration. The
provisions of this Declaration, to the extent that they restrict the duties and
liabilities of an Indemnified Person otherwise existing at law or in equity
(other than the duties imposed on the Property Trustee under the Trust Indenture
Act), are agreed by the parties hereto to replace such other duties and
liabilities of such Indemnified Person.

                  (b) Unless otherwise expressly provided herein:

                         (i)  whenever a conflict of interest exists or arises
         between any Covered Persons; or

                        (ii) whenever this Declaration or any other agreement
         contemplated herein or therein provides that an Indemnified Person
         shall act in a manner that is, or provides terms that are, fair and
         reasonable to the Trust or any Holder of Securities,

each Covered Person or Indemnified Person shall resolve such conflict of
interest, take such action or provide such terms, considering in each case the
relative interest of each party (including its own interest) to such conflict,
agreement, transaction or situation and the benefits and burdens relating to


                                       73

<PAGE>


such interests, any customary or accepted industry practices, and any applicable
generally accepted accounting practices or principles. In the absence of bad
faith by the Indemnified Person, the resolution, action or term so made, taken
or provided by the Indemnified Person shall not constitute a breach of this
Declaration or any other agreement contemplated herein or of any duty or
obligation of the Indemnified Person at law or in equity or otherwise.

                  (c) Whenever in this Declaration an Indemnified Person is
permitted or required to make a decision:

                         (i) in its "discretion" or under a grant of similar
         authority, the Indemnified Person shall be entitled to consider such
         interests and factors as it desires, including its own interests, and
         shall have no duty or obligation to give any consideration to any
         interest of or factors affecting the Trust or any other Person; or

                        (ii) in its "good faith" or under another express
         standard, the Indemnified Person shall act under such express standard
         and shall not be subject to any other or different standard imposed by
         this Declaration or by applicable law.

SECTION 10.4      Indemnification.

                           (a) (i) The Sponsor shall indemnify, to the full
         extent permitted by law, any Company Indemnified Person who was or is a
         party or is threatened to be made a party to any threatened, pending or
         completed action, suit or proceeding, whether civil, criminal,
         administrative or investigative (other than an action by or in the
         right of the Trust) by reason of the fact that he is or was a Company
         Indemnified Person against expenses (including attorneys' fees and
         expenses), judgments, fines and amounts paid in settlement actually and
         reasonably incurred by him in connection with such action, suit or
         proceeding if he acted in good faith and in a manner he reasonably
         believed to be in or not opposed to the best interests of the Trust,
         and, with respect to any criminal action or proceeding, had no
         reasonable cause to believe his conduct was unlawful. The termination
         of any action, suit or proceeding by judgment, order, settlement,


                                       74

<PAGE>


         conviction, or upon a plea of nolo contendere or its equivalent, shall
         not, of itself, create a presumption that the Company Indemnified
         Person did not act in good faith and in a manner which he reasonably
         believed to be in or not opposed to the best interests of the Trust,
         and with respect to any criminal action or proceeding, had reasonable
         cause to believe that his conduct was unlawful.

                        (ii) The Sponsor shall indemnify, to the full extent
         permitted by law, any Company Indemnified Person who was or is a party
         or is threatened to be made a party to any threatened, pending or
         completed action or suit by or in the right of the Trust to procure a
         judgment in its favor by reason of the fact that he is or was a Company
         Indemnified Person against expenses (including attorneys' fees and
         expenses) actually and reasonably incurred by him in connection with
         the defense or settlement of such action or suit if he acted in good
         faith and in a manner he reasonably believed to be in or not opposed to
         the best interests of the Trust and except that no such indemnification
         shall be made in respect of any claim, issue or matter as to which such
         Company Indemnified Person shall have been adjudged to be liable to the
         Trust unless and only to the extent that the Court of Chancery of
         Delaware or the court in which such action or suit was brought shall
         determine upon application that, despite the adjudication of liability
         but in view of all the circumstances of the case, such Person is fairly
         and reasonably entitled to indemnity for such expenses which such Court
         of Chancery or such other court shall deem proper.

                       (iii) To the extent that a Company Indemnified Person
         shall be successful on the merits or otherwise (including dismissal of
         an action without prejudice or the settlement of an action without
         admission of liability) in defense of any action, suit or proceeding
         referred to in paragraphs (i) and (ii) of this Section 10.4(a), or in
         defense of any claim, issue or matter therein, he shall be indemnified,
         to the full extent permitted by law, against expenses (including
         attorneys' fees) actually and reasonably incurred by him in connection
         therewith.

                        (iv) Any indemnification under paragraphs (i) and (ii)
         of this Section 10.4(a) (unless ordered by a court) shall be made by
         the Sponsor only as authorized in the specific case upon a
         determination that indemnification of the Company Indemnified Person is
         proper in the circumstances because he has met the applicable standard
         of conduct set forth in paragraphs (i) and (ii). Such determination
         shall be made (1) by the Administrative Trustees by a majority vote of
         a quorum consisting of such Administrative Trustees who were not
         parties to such action, suit or proceeding, (2) if such a quorum is not
         obtainable, or, even if obtainable, if a quorum of disinterested
         Administrative Trustees so directs, by independent legal counsel in a
         written opinion, or (3) by the Common Security Holder of the Trust.

                         (v) Expenses (including attorneys' fees and expenses)
         incurred by a Company Indemnified Person in defending a civil,
         criminal, administrative or investigative action, suit or proceeding
         referred to in paragraphs (i) and (ii) of this Section 10.4(a) shall be
         paid by the Sponsor in advance of the final disposition of such action,
         suit or proceeding upon receipt of an undertaking by or on behalf of
         such Company Indemnified Person to repay such amount if it shall
         ultimately be determined that he is not entitled to be indemnified by
         the Sponsor as authorized in this Section 10.4(a). Notwithstanding the
         foregoing, no advance shall be made by the Sponsor if a determination
         is reasonably and promptly made (i) by the Administrative Trustees by a
         majority vote of a quorum of disinterested Administrative Trustees,
         (ii) if such a quorum is not obtainable, or, even if obtainable, if a
         quorum of disinterested Administrative Trustees so directs, by
         independent legal counsel in a written opinion or (iii) the Common
         Security Holder of the Trust, that, based upon the facts known to the
         Administrative Trustees, counsel or the Common Security Holder at the
         time such determination is made, such Company Indemnified Person acted
         in bad faith or in a manner that such Person did not believe to be in
         or not opposed to the best interests of the Trust, or, with respect to
         any criminal proceeding, that such Company Indemnified Person believed
         or had reasonable cause to believe his conduct was unlawful. In no
         event shall any advance be made in instances where the Administrative
         Trustees, independent legal counsel or Common Security Holder
         reasonably determine that such Person deliberately breached his duty to
         the Trust or its Common or Capital Security Holders.

                        (vi) The indemnification and advancement of expenses
         provided by, or granted pursuant to, the other paragraphs of this
         Section 10.4(a) shall not be deemed exclusive of any other rights to
         which those seeking indemnification and advancement of expenses may be
         entitled under any agreement, vote of stockholders or disinterested
         directors of the Sponsor or Capital Security Holders of the Trust or
         otherwise, both as to action in his official capacity and as to action
         in another capacity while holding such office. All rights to
         indemnification under this Section 10.4(a) shall be deemed to be
         provided by a contract between the Sponsor and each Company Indemnified
         Person who serves in such capacity at any time while this Section
         10.4(a) is in effect. Any repeal or modification of this Section
         10.4(a) shall not affect any rights or obligations then existing.

                       (vii) The Sponsor or the Trust may purchase and maintain
         insurance on behalf of any Person who is or was a Company Indemnified
         Person against any liability asserted against him and incurred by him
         in any such capacity, or arising out of his status as such, whether or
         not the Sponsor would have the power to indemnify him against such
         liability under the provisions of this Section 10.4(a).

                      (viii) For purposes of this Section 10.4(a), references to
         "the Trust" shall include, in addition to the resulting or surviving
         entity, any constituent entity (including any constituent of a
         constituent) absorbed in a consolidation or merger, so that any Person
         who is or was a director, trustee, officer or employee of such
         constituent entity, or is or was serving at the request of such
         constituent entity as a director, trustee, officer, employee or agent
         of another entity, shall stand in the same position under the
         provisions of this Section 10.4(a) with respect to the resulting or
         surviving entity as he would have with respect to such constituent
         entity if its separate existence had continued.

                        (ix) The indemnification and advancement of expenses
         provided by, or granted pursuant to, this Section 10.4(a) shall, unless
         otherwise provided when authorized or ratified, continue as to a Person
         who has ceased to be a Company Indemnified Person and shall inure to
         the benefit of the heirs, executors and administrators of such a
         Person.

                  (b) The Sponsor agrees to indemnify the (i) Property Trustee,
(ii) the Delaware Trustee, (iii) any Affiliate of the Property Trustee or the
Delaware Trustee, and (iv) any officers, directors, shareholders, members,
partners, employees, representatives, custodians, nominees or agents of the
Property Trustee or the Delaware Trustee (each of the Persons in (i) through
(iv) being referred to as a "Fiduciary Indemnified Person") for, and to hold
each Fiduciary Indemnified Person harmless against, any and all loss, liability,
damage, claim or expense including taxes (other than taxes based on the income
of such Fiduciary Indemnified Person) 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 10.4(b) shall survive the resignation or
removal of the Property Trustee or the Delaware Trustee and the satisfaction and
discharge of this Declaration.

                  (c) The Sponsor agrees to pay the Property Trustee and the
Delaware Trustee, from time to time, such compensation for all services rendered
by the Property Trustee and the Delaware Trustee hereunder as may be mutually
agreed upon in writing by the Sponsor and the Property Trustee or the Delaware
Trustee, as the case may be, and, except as otherwise expressly provided herein,
to reimburse the Property Trustee and the Delaware Trustee upon its or their
request for all reasonable expenses, disbursements and advances incurred or made
by the Property Trustee or the Delaware Trustee, as the case may be, in
accordance with the provisions of this Declaration, except any such expense,
disbursement or advance as may be attributable to its or their negligence or bad
faith.

SECTION 10.5      Outside Businesses.

                  Any Covered Person, the Sponsor, the Delaware Trustee and the
Property Trustee may engage in or possess an interest in other business ventures
of any nature or description, independently or with others, similar or
dissimilar to the business of the Trust, and the Trust and the Holders of
Securities shall have no rights by virtue of this Declaration in and to such
independent ventures or the income or profits derived therefrom, and the pursuit
of any such venture, even if competitive with the business of the Trust, shall
not be deemed wrongful or improper. No Covered Person, the Sponsor, the Delaware
Trustee, or the Property Trustee shall be obligated to present any particular
investment or other opportunity to the Trust even if such opportunity is of a
character that, if presented to the Trust, could be taken by the Trust, and any
Covered Person, the Sponsor, the Delaware Trustee and the Property Trustee shall
have the right to take for its own account (individually or as a partner or
fiduciary) or to recommend to others any such particular investment or other
opportunity. Any Covered Person, the Delaware Trustee and the Property Trustee
may engage or be interested in any financial or other transaction with the
Sponsor or any Affiliate of the Sponsor, or may act as depositary for, trustee
or agent for, or act on any committee or body of holders of, securities or other
obligations of the Sponsor or its Affiliates.

                                   ARTICLE XI

                  The fiscal year ("Fiscal Year") of the Trust shall be the
calendar year, or such other year as is required by the Code.

SECTION 11.2      Certain Accounting Matters.

                  (a) At all times during the existence of the Trust, the
Administrative Trustees shall keep, or cause to be kept, full books of account,
records and supporting documents, which shall reflect in reasonable detail, each
transaction of the Trust. The books of account shall be maintained on the
accrual method of accounting, in accordance with generally accepted accounting
principles, consistently applied. The Trust shall use the accrual method of
accounting for United States federal income tax purposes. The books of account

                                       79

<PAGE>


and the records of the Trust shall be examined by and reported upon as of the
end of each Fiscal Year of the Trust by a firm of independent certified public
accountants selected by the Administrative Trustees.

                  (b) The Administrative Trustees shall cause to be prepared and
delivered to each of the Holders of Securities, within 90 days after the end of
each Fiscal Year of the Trust, annual financial statements of the Trust,
including a balance sheet of the Trust as of the end of such Fiscal Year, and
the related statements of income or loss.

                  (c) The Administrative Trustees shall cause to be duly
prepared and delivered to each of the Holders of Securities, any annual United
States federal income tax information statement, required by the Code,
containing such information with regard to the Securities held by each Holder as
is required by the Code and the Treasury Regulations. Notwithstanding any right
under the Code to deliver any such statement at a later date, the Administrative
Trustees shall endeavor to deliver all such information statements within 30
days after the end of each Fiscal Year of the Trust.

                  (d) The Administrative Trustees shall cause to be duly
prepared and filed with the appropriate taxing authority, an annual United
States federal income tax return, on a Form 1041 or such other form required by
United States federal income tax law, and any other annual income tax returns
required to be filed by the Administrative Trustees on behalf of the Trust with
any state or local taxing authority.

SECTION 11.3      Banking.

                  The Trust shall maintain one or more bank accounts in the name
and for the sole benefit of the Trust; provided, however, that all payments of
funds in respect of the Debentures held by the Property Trustee shall be made
directly to the Property Trustee Account and no other funds of the Trust shall
be deposited in the Property Trustee Account. The sole signatories for such
accounts shall be designated by the Administrative Trustees; provided, however,
that the Property Trustee shall designate the signatories for the Property
Trustee Account.

SECTION 11.4      Withholding.

                  The Trust and the Administrative Trustees shall comply with
all withholding requirements under United States federal, state and local law.
The Trust shall request, and the Holders shall provide to the Trust, such forms
or certificates as are necessary to establish an exemption from withholding with
respect to each Holder, and any representations and forms as shall reasonably be
requested by the Trust to assist it in determining the extent of, and in
fulfilling, its withholding obligations. The Administrative Trustees shall file
required forms with applicable jurisdictions and, unless an exemption from
withholding is properly established by a Holder, shall remit amounts withheld
with respect to the Holder to applicable jurisdictions. To the extent that the
Trust is required to withhold and pay over any amounts to any authority with
respect to Distributions or allocations to any Holder, the amount withheld shall
be deemed to be a Distribution in the amount of the withholding to the Holder.
In the event of any claimed over withholding, Holders shall be limited to an
action against the applicable jurisdiction. If the amount required to be
withheld was not withheld from actual Distributions made, the Trust may reduce
subsequent Distributions by the amount of such withholding.

                             AMENDMENTS AND MEETINGS

SECTION 12.1      Amendments.

                  (a) Except as otherwise provided in this Declaration or by any
applicable terms of the Securities, this Declaration may only be amended by a

         Trustees);

                        (ii) if the amendment affects the rights, powers,
         duties, obligations or immunities of the Property Trustee, the Property
         Trustee; and

                       (iii) if the amendment affects the rights, powers,
         duties, obligations or immunities of the Delaware Trustee, the Delaware
         Trustee.

                  (b) No amendment shall be made, and any such purported
amendment shall be void and ineffective:

                         (i) unless, in the case of any proposed amendment, the
         Property Trustee shall have first received an Officers' Certificate
         from each of the Trust and the Sponsor that such amendment is permitted
         by, and conforms to, the terms of this Declaration (including the terms
         of the Securities);

                        (ii) unless, in the case of any proposed amendment which
         affects the rights, powers, duties, obligations or immunities of the

                  and the Sponsor that such amendment is permitted by, and
                  conforms to, the terms of this Declaration (including the
                  terms of the Securities); and

                           (B) an opinion of counsel (who may be counsel to the
                  Sponsor or the Trust) that (x) such amendment is permitted by,
                  and conforms to, the terms of this Declaration (including the
                  terms of the Securities) and (y) all conditions precedent to
                  the execution and delivery of such amendment have been
                  satisfied,

         provided, however, that the Property Trustee shall not be required to
sign any such amendment, and

                       (iii) to the extent the result of such amendment would be
         to:

                           (A) cause the Trust to fail to continue to be
                  classified for purposes of United States federal income
                  taxation as a grantor trust;


                                       82

<PAGE>


                           (B) reduce or otherwise adversely affect the powers
                  of the Property Trustee in contravention of the Trust
                  Indenture Act; or

                           (C) cause the Trust to be deemed to be an Investment
                  Company required to be registered under the Investment Company
                  Act;

                  (c) At such time after the Trust has issued any Securities
that remain outstanding, any amendment that would adversely affect the rights,
privileges or preferences of any Holder of Securities may be effected only with
such additional requirements as may be set forth in the terms of such
Securities;

                  (d) Section 10.1(c) and this Section 12.1 shall not be amended
without the consent of all of the Holders of the Securities;

                  (e) Article IV shall not be amended without the consent of the
Holders of a Majority in Liquidation Amount of the Common Securities;

                  (f) The rights of the Holders of the Common Securities under
Article V to increase or decrease the number of, and appoint and remove Trustees
shall not be amended without the consent of the Holders of a Majority in

                  (g) Notwithstanding Section 12.1(c), this Declaration may be
amended without the consent of the Holders of the Securities to:

                         (i) cure any ambiguity, correct or supplement any
         provision in this Declaration that may be inconsistent with any other
         provision of this Declaration or to make any other provisions with

         shall not be inconsistent with the other provisions of the Declaration;
         and

                        (ii) to modify, eliminate or add to any provisions of
         the Declaration to such extent as shall be necessary to ensure that the
         Trust will be classified for United States federal income tax purposes
         as a grantor trust at all times that any Securities are outstanding or
         to ensure that the Trust will not be required to register as an
         Investment Company under the Investment Company Act;

                                       83

<PAGE>


provided, however, that in the case of clause (i), such action shall not
adversely affect in any material respect the interests of the Holders of the
Securities, and any amendments of this Declaration shall become effective when
notice thereof is given to the Holders of the Securities.

SECTION 12.2      Meetings of the Holders of Securities; Action by Written
                  Consent.

                  (a) Meetings of the Holders of any class of Securities may be
called at any time by the Administrative Trustees (or as provided in the terms
of the Securities) to consider and act on any matter on which Holders of such
class of Securities are entitled to act under the terms of this Declaration, the
terms of the Securities or the rules of any stock exchange on which the Capital
Securities are listed or admitted for trading. The Administrative Trustees shall
call a meeting of the Holders of such class if directed to do so by the Holders
of at least 10% in Liquidation Amount of such class of Securities. Such
direction shall be given by delivering to the Administrative Trustees one or
more notices in a writing stating that the signing Holders of Securities wish to
call a meeting and indicating the general or specific purpose for which the
meeting is to be called. Any Holders of Securities calling a meeting shall
specify in writing the Security Certificates held by the Holders of Securities
exercising the right to call a meeting and only those Securities specified shall
be counted for purposes of determining whether the required percentage set forth
in the second sentence of this paragraph has been met.

                  (b) Except to the extent otherwise provided in the terms of
the Securities, the following provisions shall apply to meetings of Holders of
Securities:

                         (i) notice of any such meeting shall be given to all
         the Holders of Securities having a right to vote thereat at least seven
         days and not more than 60 days before the date of such meeting.
         Whenever a vote, consent or approval of the Holders of Securities is
         permitted or required under this Declaration or the rules of any stock


                                       84

<PAGE>


         exchange on which the Capital Securities are listed or admitted for
         trading, such vote, consent or approval may be given at a meeting of
         the Holders of Securities. Any action that may be taken at a meeting of
         the Holders of Securities may be taken without a meeting if a consent
         in writing setting forth the action so taken is signed by the Holders
         of Securities owning not less than the minimum amount of Securities in
         Liquidation Amount that would be necessary to authorize or take such
         action at a meeting at which all Holders of Securities having a right
         to vote thereon were present and voting. Prompt notice of the taking of
         action without a meeting shall be given to the Holders of Securities
         entitled to vote who have not consented in writing. The Administrative
         Trustees may specify that any written ballot submitted to the Security
         Holder for the purpose of taking any action without a meeting shall be
         returned to the Trust within the time specified by the Administrative
         Trustees;

                        (ii) each Holder of a Security may authorize any Person
         to act for it by proxy on all matters in which a Holder of Securities
         is entitled to participate, including waiving notice of any meeting, or
         voting or participating at a meeting. No proxy shall be valid after the
         expiration of 11 months from the date thereof unless otherwise provided
         in the proxy. Every proxy shall be revocable at the pleasure of the
         Holder of Securities executing it. Except as otherwise provided herein,
         all matters relating to the giving, voting or validity of proxies shall
         be governed by the General Corporation Law of the State of Delaware
         relating to proxies, and judicial interpretations thereunder, as if the
         Trust were a Delaware corporation and the Holders of the Securities
         were stockholders of a Delaware corporation;

                       (iii)  each meeting of the Holders of the Securities
         shall be conducted by the Administrative Trustees or by such other
         Person that the Administrative Trustees may designate; and

                        (iv) unless the Business Trust Act, this Declaration,
         the terms of the Securities, the Trust Indenture Act or the listing
         rules of any stock exchange on which the Capital Securities are then


                                       85

<PAGE>


         listed or trading, otherwise provides, the Administrative Trustees, in
         their sole discretion, shall establish all other provisions relating to
         meetings of Holders of Securities, including notice of the time, place
         or purpose of any meeting at which any matter is to be voted on by any
         Holders of Securities, waiver of any such notice, action by consent
         without a meeting, the establishment of a record date, quorum
         requirements, voting in person or by proxy or any other matter with
         respect to the exercise of any such right to vote.

                       REPRESENTATIONS OF PROPERTY TRUSTEE

SECTION 13.1      Representations and Warranties of Property Trustee.

                               REGISTRATION RIGHTS

SECTION 14.1      Registration Rights Agreement; Liquidated Damages.

                  The Holders of the Capital Securities, the Debentures and the
Capital Securities Guarantee (collectively, the "Registrable Securities") are
entitled to the benefits of a Registration Rights Agreement. Pursuant to the
Registration Rights Agreement, the Sponsor and the Trust have agreed for the
benefit of the Holders of Registrable Securities that (i) they will, at the
Sponsor's cost, within 150 days after January 8, 1997 (the "Issue Date"), use
their reasonable best efforts to file a registration statement (the "Exchange
Registration Statement") relating an Exchange Offer pursuant to which each
issuer of such respective Registrable Securities would issue amounts of such
Registrable Securities as are accepted in the Exchange Offer which shall be
identical in all respects to those exchanged, except they will have been
registered under the Securities Act and will no longer be subject to transfer
restrictions under the Securities Act or the $100,000 minimum aggregate
principal or Liquidation Amount transfer restriction and, if required pursuant
to the terms of the Registration Rights Agreement, file a shelf registration
statement (the "Shelf Registration Statement") with the Commission with respect
to resales of the Registrable Securities, (ii) they will use their reasonable
best efforts to cause such Exchange Registration Statement and/or Shelf
Registration Statement, as the case requires, to be declared effective by the
Commission within 180 days after the Issue Date and (iii) they will use their
reasonable best efforts to maintain the Shelf Registration Statement, if any,
continuously effective under the Securities Act until the third anniversary of
the effectiveness of the Shelf Registration Statement or such earlier date as is
provided in the Registration Rights Agreement (the "Effectiveness Period"). All


                                       88

<PAGE>


references herein to such Registrable Securities shall be deemed to include, as
the context may require, the Registrable Securities into which such Securities
have been exchanged pursuant to the Exchange Offer ("Exchange Securities") and
all reference to numbers or amounts of such Securities shall be deemed to
include, as the context may require, such Exchanged Securities. Capitalized
terms used in this Article XIV but not otherwise defined herein shall have the
meanings ascribed to such terms in the Registration Rights Agreement.

                  If (i) (A) neither the Exchange Offer Registration Statement
         nor a Shelf Registration Statement is filed with the Commission on or
         prior to the 150th day after the Issue Date or (B) notwithstanding that
         the Debenture Issuer and the Trust have consummated or will consummate
         an Exchange Offer, the Debenture Issuer and the Trust are required to
         file a Shelf Registration Statement and such Shelf Registration
         Statement is not filed on or prior to date required by the Registration
         Rights Agreement, then commencing on the day after the applicable
         required filing date, additional Distributions shall accumulate on the
         Liquidation Amount of the Capital Securities at a rate of 0.25% per
         annum; or

                        (ii) (A) neither the Exchange Offer Registration
         Statement nor a Shelf Registration Statement is declared effective by
         the Commission on or prior to the 30th day after the applicable
         required filing date or (B) notwithstanding that the Debenture Issuer
         and the Trust have consummated or will consummate an Exchange Offer,
         the Debenture Issuer and the Trust are required to file a Shelf
         Registration Statement and such Shelf Registration Statement is not
         declared effective by the Commission on or prior to the 30th day after
         the date such Shelf Registration Statement was required to be filed,
         then, commencing on the 31st day after the applicable required filing
         date, additional Distributions shall accumulate on the Liquidation
         Amount of the Capital Securities at a rate of 0.25% per annum; or

                       (iii) (A) the Trust has not exchanged Series B Capital
         Securities for all Capital Securities or the Debenture Issuer or the
         Guarantor has not exchanged the Series B Guarantees or the Series B

         Debentures for all Series A Capital Securities Guarantees or Series A
         Debentures validly tendered, in accordance with the terms of the
         Exchange Offer on or prior to the 30th day after the date on which the
         Exchange Offer Registration Statement was declared effective or (B) if
         applicable, the Shelf Registration Statement has been declared
         effective and such Shelf Registration Statement ceases to be effective
         at any time prior to the expiration of the Rule 144(k) Period (other
         than after such time as all Capital Securities have been disposed of
         thereunder or otherwise cease to be Registrable Securities), additional
         Distributions shall accumulate on the Liquidation Amount of the Capital
         Securities at a rate of 0.25% per annum commencing on (x) the 31st day
         after such effective date, in the case of (A) above, or (y) the day
         such Shelf Registration Statement ceases to be effective in the case of
         (B) above;

provided, however, that the additional Distributions rate on the liquidation
amount of the Capital Securities may not exceed in the aggregate 0.25% per
annum; provided, further, however, that (1) upon the filing of the Exchange
Offer Registration Statement or a Shelf Registration Statement (in the case of
clause (i) above), (2) upon the effectiveness of the Exchange Offer Registration
Statement or a Shelf Registration Statement (in the case of clause (ii) above),
or (3) upon the exchange of Exchange Capital Securities, Exchange Guarantees and
Exchange Subordinated Debentures for all Capital Securities, Guarantees and
Subordinated Debentures tendered (in the case of clause (iii)(A) above), or upon
the effectiveness of the Shelf Registration Statement which had ceased to remain
effective (in the case of clause (iii)(B) above), additional Distributions on
the Liquidation Amount of the Capital Securities as a result of such clause (or
the relevant subclause thereof), as the case may be, shall cease to accumulate.

                  Any amounts of additional Distributions due pursuant to
clauses (i), (ii) or (iii) above will be payable in cash on January 1 and July 1
of each year to the Holders of record at the close of business on the fifteenth
day prior to the relevant Distribution date.

                                    ANNEX I

                                    TERMS OF
                   8.71% SERIES A/SERIES B CAPITAL SECURITIES
                             8.71% COMMON SECURITIES

                  Pursuant to Section 7.1 of the Amended and Restated
Declaration of Trust, dated as of January 13, 1997 (as amended from time to
time, the "Declaration"), the designation, rights, privileges, restrictions,
preferences and other terms and provisions of the Capital Securities and the
Common Securities (collectively, the "Securities") are set out below (each
capitalized term used but not defined herein has the meaning set forth in the
Declaration or, if not defined in such Declaration, as defined in the Offering
Memorandum referred to below in Section 2(c) of this Annex I):

                  1. Designation and Number.

                  (a) Capital Securities. 150,000 Series A Capital Securities of
the Trust and 150,000 Series B Capital Securities of the Trust, each series with
an aggregate liquidation amount with respect to the assets of the Trust of One
Hundred Fifty Million dollars ($150,000,000) and each with a liquidation amount
with respect to the assets of the Trust of $1,000 per security, are hereby
designated for the purposes of identification only as "8.71% Series A Capital
Securities" and "8.71% Series B Capital Securities", respectively (collectively,
the "Capital Securities"). The certificates evidencing the Capital Securities
shall be substantially in the form of Exhibit A-1 to the Declaration, with such
changes and additions thereto or deletions therefrom as may be required by
ordinary usage, custom or practice or to conform to the rules of any stock
exchange or quotation system on which the Capital Securities are listed or
quoted.

                  (b) Common Securities. 4,640 Common Securities of the Trust
with an aggregate liquidation amount with respect to the assets of the Trust of
Four Million Six Hundred Forty Thousand dollars ($4,640,000) and a liquidation
amount with respect to the assets of the Trust of $1,000 per security, are
hereby designated for the purposes of identification only as "8.71% Common
Securities" (the "Common Securities"). The certificates



                                       I-1

<PAGE>




evidencing the Common Securities shall be substantially in the form of Exhibit
A-2 to the Declaration, with such changes and additions thereto or deletions
therefrom as may be required by ordinary usage, custom or practice.

                  2.       Distributions.

                  (a) Distributions payable on each Security will be fixed at a
rate per annum of 8.71% (the "Coupon Rate") of the liquidation amount of $1,000
per Security (the "Liquidation Amount"), such rate being the rate of interest
payable on the Debentures to be held by the Property Trustee. Distributions in
arrears for more than one semi-annual period will bear additional distributions
thereon compounded semi-annually at the Coupon Rate (to the extent permitted by
applicable law). Pursuant to the Registration Rights Agreement, in certain
limited circumstances the Debenture Issuer will be required to pay Liquidated
Damages (as defined in the Registration Rights Agreement) with respect to the
Debentures. The term "Distributions", as used herein, includes distributions of
any such interest and Liquidated Damages payable unless otherwise stated. A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Property Trustee and to the extent the Property
Trustee has funds on hand legally available therefor.

                  (b) Distributions on the Securities will be cumulative, will
accumulate from the most recent date to which Distributions have been paid or,
if no Distributions have been paid, from January 13, 1997, and will be payable
semi-annually in arrears on January 1 and July 1 of each year, commencing on
July 1, 1997, except as otherwise described below. The amount of Distributions
payable for any period will be computed on the basis of a 360-day year
consisting of twelve 30-day months and for any period less than a full calendar
month on the basis of the actual number of days elapsed in such month. If any
date on which Distributions are payable on the Securities is not a Business Day,
then payment of the Distribution payable on such date shall be made on the next
succeeding day that is a Business Day (and without any interest or other payment
in respect of any such delay), with the same force and effect as if made on such
date (each date on which Distributions are payable in accordance with the
foregoing, a "Distribution Date"). As long as no Event of Default has occurred
and is continuing under the Indenture,

                                       I-2

<PAGE>






the Debenture Issuer has the right under the Indenture to defer payments of
interest by extending the interest payment period at any time and from time to
time on the Debentures for a period not exceeding 10 consecutive semi-annual
periods, including the first such semi-annual period during such period (each an
"Extension Period"), provided that no Extension Period shall extend beyond the
Maturity Date of the Debentures. Upon any such election, distributions will be
deferred during such Extension Period. Notwithstanding such deferral,
Distributions to which Holders of Securities are entitled shall continue to
accumulate with additional Distributions thereon (to the extent permitted by
applicable law but not at a rate greater than the rate at which interest is then
accruing on the Debentures) at the Coupon Rate compounded semi-annually from the
relevant Distribution Date, during any such Extension Period. Prior to the
expiration of any such Extension Period, the Debenture Issuer may further defer
payments of interest by further extending such Extension Period; provided that
such Extension Period, together with all such previous and further extensions
within such Extension Period, may not exceed 10 consecutive semi-annual periods,
including the first semi-annual period during such Extension Period, or extend
beyond the Maturity Date of the Debentures. Upon the expiration of any Extension
Period and the payment of all amounts then due, the Debenture Issuer may
commence a new Extension Period, subject to the above requirements.

                  (c) Distributions on the Securities will be payable to the
Holders thereof as they appear on the books and records of the Trust at the
close of business on the date fifteen days prior to the relevant Distribution
Date, which Distribution Dates correspond to the interest payment dates on the
Debentures. Subject to any applicable laws and regulations and the provisions of
the Declaration, each such payment in respect of the Capital Securities will be
made as follows: (i) if the Capital Securities are held in global form by a
Clearing Agency (or its nominee), in accordance with the procedures of the
Clearing Agency; and (ii) if the Capital Securities are held in definitive form
by check mailed to the address of the Holder thereof as reflected in the records
of the Registrar unless otherwise agreed by the Trust. The relevant record dates
for the Common Securities shall be the same as the record dates for the Capital
Securities. Distributions payable on any Securities that are not punctually paid
on any Distribution Date, as a result of the Debenture



                                       I-3

<PAGE>


Issuer having failed to make a payment under the Debentures, will cease to be
payable to the Holder on the relevant record date, and such defaulted
Distribution will instead be payable to the Person in whose name such Securities
are registered on the special record date or other specified date determined in
accordance with the Indenture.

                  (d) In the event that there is any money or other property
held by or for the Trust that is not accounted for hereunder, such property
shall be distributed Pro Rata (as defined herein) pursuant to Section 8 among
the Holders of the Securities.

                  3.  Liquidation Distribution Upon Dissolution.

                  In the event of any termination of the Trust or the Sponsor
otherwise gives notice of its election to liquidate the Trust pursuant to
Section 8.1(a)(iii) of the Declaration, the Trust shall be liquidated by the
Administrative Trustees as expeditiously as the Administrative Trustees
determine to be possible by distributing, after satisfaction of liabilities to
creditors of the Trust as provided by applicable law, to the Holders of the
Securities a Like Amount (as defined below) of the Debentures, unless such
distribution is determined by the Property Trustee not to be practicable, in
which event such Holders will be entitled to receive out of the assets of the
Trust legally available for distribution to Holders, after
satisfaction of liabilities to creditors of the Trust as provided by applicable
law, an amount equal to the aggregate of the Liquidation Amount of $1,000 per
Security plus accumulated and unpaid Distributions thereon to the date of
payment (such amount being the "Liquidation Distribution").

                  "Like Amount" means (i) with respect to a redemption of the
Securities, Securities having a Liquidation Amount equal to the principal amount
of Debentures to be paid in accordance with their terms and (ii) with respect to
a distribution of Debentures upon the liquidation of the Trust, Debentures
having a principal amount equal to the Liquidation Amount of the Securities of
the Holder to whom such Debentures are distributed.

                  If, upon any such liquidation, the Liquidation Distribution
can be paid only in part because the Trust has

                                       I-4

<PAGE>


insufficient assets on hand legally available to pay in full the aggregate
Liquidation Distribution, then the amounts payable directly by the Trust on the
Securities shall be paid on a Pro Rata basis as set forth in Section 8.

                  4. Redemption and Distribution.

                  (a) Upon the repayment of the Debentures on the Maturity Date
(as defined in the Indenture, which includes any advancement of the Maturity
Date pursuant to Section 14.06 of the Indenture) thereof or prepayment thereof
(in whole or in part) prior thereto in accordance with the terms thereof, the
proceeds from such repayment or prepayment shall be simultaneously applied by
the Property Trustee (subject to the Property Trustee having received notice no
later than 45 days prior to such repayment or prepayment) to redeem a Like
Amount of the Securities at a redemption price equal to (i) in the case of the
repayment of the Debentures on the Maturity Date, the Maturity Redemption Price
(as defined below), (ii) in the case of the optional prepayment of the
Debentures upon the occurrence and continuation of a Special Event, the Special
Event Redemption Price (as defined below) and (iii) in the case of the optional
prepayment of the Debentures other than as a result of the occurrence and
continuance of a Special Event, the Optional Redemption Price (as defined
below). The Maturity Redemption Price, the Special Event Redemption Price and
the Optional Redemption Price are referred to collectively as the "Redemption
Price." Holders will be given not less than 30 nor more than 60 days notice of
such redemption.

                  (b) (i) The "Maturity Redemption Price", with respect to a
redemption of Securities, shall mean an amount equal to the principal of and
accrued interest on the Debentures as of the Maturity Date thereof.

                      (ii) The Debenture Issuer shall have the right (subject to
the conditions in the Indenture) to elect to prepay the Debentures to whole or
in part at any time on or after January 1, 2007 (the "Initial Optional
Redemption Date"), upon not less than 30 days and not more than 60 days notice,
at the Optional Prepayment Price (as defined in the Indenture) and, simultaneous
with such prepayment, to cause a Like Amount of the Securities to be redeemed at
the Optional Redemption Price on a Pro Rata basis. "Optional Redemption Price"
shall mean a price



                                       I-5

<PAGE>




equal to the percentage of the Liquidation Amount of Securities to be redeemed
plus accumulated and unpaid Distributions thereon, if any, to the date of such
redemption if redeemed during the 12 month period beginning January 1 of the
years indicated below:


                Year                   Percentage

                2007                    104.355%

                2008                    103.920%

                2009                    103.484%

                2010                    103.049%

                2011                    102.613%

                2012                    102.178%

                2013                    101.742%

                2014                    101.307%

                2015                    100.871%

                2016                    100.436%

                2017 and thereafter     100.000%


                  (c) If at any time a Tax Event or an Investment Company Event
(each as defined below, and each a "Special Event") occurs, the Debenture Issuer
shall have the right (subject to the conditions set forth in the Indenture) at
any time prior to the Initial Optional Redemption Date, upon not less than 30
nor more than 60 days notice, to prepay the Debentures in whole, but not in
part, within the 90 days following the occurrence of such Special Event (the "90
Day Period"), and, simultaneous with such redemption, to cause a Like Amount of
the Securities to be redeemed by the Trust at the Special Event Redemption Price
on a Pro Rata basis.

                  "Tax Event" shall mean the receipt by the Sponsor and the
Trust of an Opinion of Counsel, requested by the Sponsor, (a "Tax Event
Opinion") experienced in such matters to the effect that, as a result of any
amendment to, or change (including any announced prospective change) in, the
laws or any regulations thereunder of the United States or any political
subdivision or taxing authority thereof or therein, or as a result of any



                                       I-6

<PAGE>




official administrative written decision or pronouncement or judicial decision
interpreting or applying such laws or regulations, which amendment or change is
effective or which pronouncement or decision is made on or after January 13,
1997, there is more than an insubstantial risk that (i) the Trust is, or will be
within 90 days of the date of such opinion, subject to United States federal
income tax with respect to income received or accrued on the Debentures, (ii)
interest payable by the Debenture Issuer on the Debentures is not, or within 90
days of the date of such opinion, will not be, deductible by the Debenture
Issuer, in whole or in part, for United States federal income tax purposes, or
(iii) the Trust is, or will be within 90 days of the date of such opinion,
subject to more than a de minimis amount of other taxes, duties or other
governmental charges.

                  "Investment Company Event" means the Sponsor and the Trust
shall have received an opinion, requested by the Sponsor of counsel experienced
in practice under the Investment Company Act of 1940, as amended (the "1940
Act"), to the effect that, as a result of the occurrence of a change in law or
regulation or a change in interpretation or application of law or regulation by
any legislative body, court, governmental agency or regulatory authority (a
"Change in 1940 Act Law"), there is more than an insubstantial risk that the
Trust is or will be considered an "investment company" which is required to be
registered under the 1940 Act, which Change in 1940 Act Law becomes effective on
or after January 13, 1997.

                  "Special Event Redemption Price" shall mean an amount in cash
equal to the greater of (i) 100% of the Liquidation Amount of the Securities and
(ii) the sum, as determined by a Quotation Agent (as defined in the Indenture),
of the present values of the principal amount and premium payable as part of the
Optional Redemption Price on the Initial Optional Redemption Date together with
the scheduled payments of interest thereon from the prepayment date to and
including the Initial Optional Redemption Date, discounted to the redemption
date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day
months) at the Adjusted Treasury Rate (as defined in the Indenture), plus, in
each case, accumulated and unpaid Distributions thereon, if any, to the date of
such redemption.



                                       I-7

<PAGE>



                  (d) On and from the date fixed by the Administrative Trustees
for any distribution of Debentures and liquidation of the Trust: (i) the
Securities will no longer be deemed to be outstanding, (ii) the Clearing Agency
or its nominee (or any successor Clearing Agency or its nominee), as the Holder
of the Capital Securities, will receive a registered global certificate or
certificates representing the Debentures to be delivered upon such distribution
and (iii) any certificates representing Securities not held by the Clearing
Agency or its nominee (or any successor Clearing Agency or its nominee) will be
deemed to represent beneficial interests in a Like Amount of Debentures until
such certificates are presented to the Administrative Trustees or their agent
for cancellation, whereupon the Debenture Issuer will issue to such holder, and
the Debenture Trustee will authenticate, a certificate representing such
Debentures.

                  (e) The Trust may not redeem fewer than all the outstanding
Securities unless all accumulated and unpaid Distributions have been paid on all
Securities for all semi-annual Distribution periods that expire on or before the
date of redemption.

                  (f)  The procedure with respect to redemptions or
distributions of Debentures shall be as follows:

                  (i) Notice of any redemption of, or notice of distribution of
        Debentures in exchange for, the Securities (a "Redemption/Distribution
        Notice") will be given by the Trust by mail to each Holder of Securities
        to be redeemed or exchanged not fewer than 30 nor more than 60 days
        before the date fixed for redemption or exchange thereof which, in the
        case of a redemption, will be the date fixed for repayment or prepayment
        of the Debentures. For purposes of the calculation of the date of
        redemption or exchange and the dates on which notices are given pursuant
        to this Section 4(f)(i), a Redemption/Distribution Notice shall be
        deemed to be given on the day such notice is first mailed by first-class
        mail, postage prepaid, to Holders of Securities. Each
        Redemption/Distribution Notice shall be addressed to the Holders of
        Securities at the address of each such Holder appearing in the books and
        records of the Trust. No defect in the Redemption/Distribution Notice or
        in the mailing of



                                       I-8

<PAGE>




        either thereof with respect to any Holder shall affect the validity of
        the redemption or exchange proceedings with respect to any other Holder.

            (ii) In the event that fewer than all the outstanding Securities are
        to be redeemed, the Securities to be redeemed shall be redeemed Pro Rata
        from each Holder of Capital Securities, it being understood that, in
        respect of Capital Securities registered in the name of and held of
        record by the Clearing Agency or its nominee (or any successor Clearing
        Agency or its nominee) or any nominee, the distribution of the proceeds
        of such redemption will be made to the Clearing Agency and disbursed by
        such Clearing Agency in accordance with the procedures applied by such
        agency or nominee.

           (iii) If Securities are to be redeemed and the Trust gives a
        Redemption/Distribution Notice, (which notice will be irrevocable), then
        (A) with respect to Capital Securities registered in the name of or held
        of record by a Clearing Agency or its nominee, by 12:00 noon, New York
        City time, on the redemption date, provided that the Debenture Issuer
        has paid the Property Trustee a sufficient amount of cash in connection
        with the related maturity or prepayment of the Debentures by 10:00 a.m.,
        New York City time, on the Maturity Date or the date of prepayment, as
        the case may be, the Property Trustee will deposit irrevocably with the
        Clearing Agency or its nominee (or successor Clearing Agency or its
        nominee) funds sufficient to pay the applicable Redemption Price with
        respect to such Capital Securities and will give the Clearing Agency
        irrevocable instructions and authority to pay the Redemption Price to
        the relevant Clearing Agency Participants, and (B) with respect to
        Capital Securities issued in certificated form and Common Securities,
        provided that the Debenture Issuer has paid the Property Trustee a
        sufficient amount of cash in connection with the related maturity or
        prepayment of the Debentures, the Property Trustee will pay the relevant
        Redemption Price to the Holders of such Securities by check mailed to
        the address of the relevant Holder appearing on the books and records of
        the Trust on the redemption date. If a Redemption/Distribution Notice
        shall have been given and funds deposited as required, if applicable,
        then immediately



                                       I-9

<PAGE>



        prior to the close of business on the date of such deposit, or on the
        redemption date, as applicable, Distributions will cease to accumulate
        on the Securities so called for redemption and all rights of Holders of
        such Securities so called for redemption will cease, except the right of
        the Holders of such Securities to receive the Redemption Price, but
        without interest on such Redemption Price, and such Securities shall
        cease to be outstanding.

            (iv) Payment of accumulated and unpaid Distributions on the
        Redemption Date of the Securities will be subject to the rights of
        Holders of Securities on the close of business on a regular record date
        in respect of a Distribution Date occurring on or prior to such
        Redemption Date.

            (v) Neither the Administrative Trustees nor the Trust shall be
        required to register or cause to be registered the transfer of (i) any
        Securities beginning on the opening of business 15 days before the day
        of mailing of a notice of redemption or any notice of selection of
        Securities for redemption or (ii) any Securities selected for redemption
        (except the unredeemed portion of any Security being redeemed). If any
        date fixed for redemption of Securities is not a Business Day, then
        payment of the Redemption Price payable on such date will be made on the
        next succeeding day that is a Business Day (and without any interest or
        other payment in respect of any such delay), with the same force and
        effect as if made on such date fixed for redemption. If payment of the
        Redemption Price in respect of any Securities is improperly withheld or
        refused and not paid either by the Property Trustee or the Paying Agent
        or by the Sponsor as guarantor pursuant to the relevant Securities
        Guarantee, Distributions on such Securities will continue to accumulate
        from the original redemption date to the actual date of payment, in
        which case the actual payment date will be considered the date fixed for
        redemption for purposes of calculating the Redemption Price.

           (vi) Redemption/Distribution Notices shall be sent by the Property
        Trustee on behalf of the Trust to (A) in respect of the Capital
        Securities, the Clearing Agency or its nominee (or any successor
        Clearing Agency or its nominee) if the Global Certificates have been
        issued or, if



                                      I-10

<PAGE>

        Definitive Capital Security Certificates have been issued,
        to the Holder thereof, and (B) in respect of the Common Securities to
        the Holder thereof.

          (vii) Subject to the foregoing and applicable law (including, without
        limitation, United States federal securities laws and banking laws),
        provided the acquiror is not the Holder of the Common Securities or the
        obligor under the Indenture, the Sponsor or any of its Affiliates may at
        any time and from time to time purchase outstanding Capital Securities
        by tender, in the open market or by private agreement.

                  5.       Voting Rights - Capital Securities.

                  (a) Except as provided under Sections 5(b) and 7 and as
otherwise required by law and the Declaration, the Holders of the Capital
Securities will have no voting rights.

                  (b) So long as any Debentures are held by the Property
Trustee, the Trustees shall not (i) direct the time, method and place of
conducting any proceeding for any remedy available to the Debenture Trustee, or
executing any trust or power conferred on such Debenture Trustee with respect to
the Debentures, (ii) waive any past default that is waivable under Section 5.07
of the Indenture, (iii) exercise any right to rescind or annul a declaration of
acceleration of the maturity of the principal of the Debentures or (iv) consent
to any amendment, modification or termination of the Indenture or the
Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of a Majority in Liquidation Amount
of all outstanding Capital Securities; provided, however, that where a consent
under the Indenture would require the consent of each holder of Debentures
affected thereby, no such consent shall be given by the Property Trustee without
the prior approval of each Holder of the Capital Securities. The Trustees shall
not revoke any action previously authorized or approved by a vote of
the Holders of the Capital Securities except by subsequent vote of such Holders.
The Property Trustee shall notify each Holder of Capital Securities of any
notice of default with respect to the Debentures. In addition to obtaining the
foregoing approvals of such Holders of the Capital Securities, prior to taking
any of the foregoing actions, the Trustees



                                      I-11

<PAGE>



shall obtain an opinion of counsel experienced in such matters to the effect
that the Trust will not be classified as an association taxable as a corporation
for United States federal income tax purposes on account of such action.

                  If an Event of Default under the Declaration has occurred and
is continuing and such event is attributable to the failure of the Debenture
Issuer to pay principal of or premium, if any, or interest on the Debentures on
any due date (including any Interest Payment Date or prepayment date or Maturity
Date), then a Holder of Capital Securities may directly institute a proceeding
for enforcement of payment to such Holder of the principal of or premium, if
any, or interest on a Like Amount of Debentures (a "Direct Action") on or after
the respective due date specified in the Debentures. In connection with such
Direct Action, the rights of the Common Securities Holder will be subrogated to
the rights of such Holder of Capital Securities to the extent of any payment
made by the Debenture Issuer to such Holder of Capital Securities in such Direct
Action. Except as provided in the second preceding sentence, the Holders of
Capital Securities will not be able to exercise directly any other remedy
available to the holders of the Debentures.

                  Any approval or direction of Holders of Capital Securities may
be given at a separate meeting of Holders of Capital Securities convened for
such purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent. The Property Trustee will cause a notice of any
meeting at which Holders of Capital Securities are entitled to vote, or of any
matter upon which action by written consent of such Holders is to be taken, to
be mailed to each Holder of record of Capital Securities. Each such notice will
include a statement setting forth (i) the date of such meeting or the date by
which such action is to be taken, (ii) a description of any resolution proposed
for adoption at such meeting on which such Holders are entitled to vote or of
such matter upon which written consent is sought and (iii) instructions for the
delivery of proxies or consent.

                  No vote or consent of the Holders of the Capital Securities
will be required for the Trust to redeem and cancel Capital Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.



                                      I-12

<PAGE>




                  Notwithstanding that Holders of Capital Securities are
entitled to vote or consent under any of the circumstances described above, any
of the Capital Securities that are owned by the Sponsor or any Affiliate of the
Sponsor shall not be entitled to vote or consent and shall, for purposes of such
vote or consent, be treated as if they were not outstanding.

                  6. Voting Rights - Common Securities.

                  (a) Except as provided under Sections 6(b), 6(c), and 7 as
otherwise required by law and the Declaration, the Holders of the Common
Securities will have no voting rights.

                  (b) Unless a Debenture Event of Default shall have occurred
and be continuing, any Trustee may be removed at any time by the Holder of the
Common Securities. If a Debenture Event of Default has occurred and is
continuing, the Property Trustee and the Delaware Trustee may be removed at such
time by the holders of a Majority in Liquidation Amount of the outstanding
Capital Securities. In no event will the Holders of the Capital Securities have
the right to vote to appoint, remove or replace the Administrative Trustees,
which voting rights are vested exclusively in the Sponsor as the holder of the
Common Securities. No resignation or removal of a Trustee and no appointment of
a successor trustee shall be effective until the acceptance of appointment by
the successor trustee in accordance with the provisions of the Declaration.

                  (c) So long as any Debentures are held by the Property
Trustee, the Trustees shall not (i) direct the time, method and place of
conducting any proceeding for any remedy available to the Debenture Trustee, or
executing any trust or power conferred on such Debenture Trustee with respect to
the Debentures, (ii) waive any past default that is waivable under Section 5.07
of the Indenture, (iii) exercise any right to rescind or annul a declaration of
acceleration of the maturity of the principal of the Debentures or (iv) consent
to any amendment, modification or termination of the Indenture or the
Debentures, where such consent shall be required, without, in each case,
obtaining the prior approval of the Holders of a Majority in Liquidation Amount
of all outstanding Common Securities; provided, however, that where a consent
under the Indenture would require the consent of each holder of Debentures
affected thereby, no such consent shall






                                      I-13

<PAGE>


be given by the Property Trustee without the prior approval of each Holder of
the Common Securities. The Trustees shall not revoke any action previously
authorized or approved by a vote of the Holders of the Common Securities except
by subsequent vote of such Holders. The Property Trustee shall notify each
Holder of Common Securities of any notice of default with respect to the
Debentures. In addition to obtaining the foregoing approvals of such Holders of
the Common Securities, prior to taking any of the foregoing actions, the
Trustees shall obtain an Opinion of Counsel experienced in such matters to the
effect that the Trust will not be classified as an association taxable as a
corporation for United States federal income tax purposes on account of such
action.

                  If an Event of Default under the Declaration has occurred and
is continuing and such event is attributable to the failure of the Debenture
Issuer to pay principal of or premium, if any, or interest on the Debentures on
the due date (including any Interest Payment Date or prepayment date or Maturity
Date) (or in the case of redemption, on the redemption date), then a Holder of
Common Securities may institute a Direct Action for enforcement of payment to
such Holder of the principal of or premium, if any, or interest on a Like Amount
of Debentures on or after the respective due date specified in the Debentures.
In connection with Direct Action, the rights of the Holders of Capital
Securities will be subrogated to the rights of such Holder of Common Securities
to the extent of any payment made by the Debenture Issuer to such Holder of
Common Securities in such Direct Action. Except as provided in the second
preceding sentence, the Holders of Common Securities will not be able to
exercise directly any other remedy available to the holders of the Debentures.

                  Any approval or direction of Holders of Common Securities may
be given at a separate meeting of Holders of Common Securities convened for such
purpose, at a meeting of all of the Holders of Securities in the Trust or
pursuant to written consent. The Administrative Trustees will cause a notice of
any meeting at which Holders of Common Securities are entitled to vote, or of
any matter upon which action by written consent of such Holders is to be taken,
to be mailed to each Holder of record of Common Securities. Each such notice
will include a statement setting forth (i) the date of such meeting or the date


                                      I-14

<PAGE>


by which such action is to be taken, (ii) a description of any resolution
proposed for adoption at such meeting on which such Holders are entitled to vote
or of such matter upon which written consent is sought and (iii) instructions
for the delivery of proxies or consents.

                  No vote or consent of the Holders of the Common Securities
will be required for the Trust to redeem and cancel Common Securities or to
distribute the Debentures in accordance with the Declaration and the terms of
the Securities.

                  7. Amendments to Declaration and Indenture.

                  In addition to the requirements set out in Section 12.1 of the
Declaration, the Declaration may be amended from time to time by the Sponsor and
the Trustees, without the consent of the Holders of the Securities (i) to cure
any ambiguity, correct or supplement any provisions in the Declaration that may
be inconsistent with any other provisions, or to make any other provisions with
respect to matters or questions arising under the Declaration which shall not be
inconsistent with the other provisions of the Declaration, or (ii) to modify,
eliminate or add to any provisions of the Declaration to such extent as shall be
necessary to ensure that the Trust will be classified for United States federal
income tax purposes as a grantor trust at all times that any Securities are
outstanding or to ensure that the Trust will not be required to register as an
"investment company" under the Investment Company Act; provided, however, that
in the case of clause (i), such action shall not adversely affect in any
material respect the interests of any Holder of Securities. Any amendments of
the Declaration pursuant to the foregoing shall become effective when notice
thereof is given to the holders of the Securities. The Declaration also may be
amended by the Trustees and the Sponsor with (i) the consent of Holders
representing a Majority in Liquidation Amount of all outstanding Securities, and
(ii) receipt by the Trustees of an Opinion of Counsel to the effect that such
amendment or the exercise of any power granted to the Trustees in accordance
with such amendment will not affect the Trust's status as a grantor trust for
United States federal income tax purposes or the Trust's exemption from status
as an investment company under the Investment Company Act, provided that,
without the consent of each Holder of Trust Securities, the Declaration may not




                                      I-15

<PAGE>





be amended to (i) change the amount or timing of any Distribution on the Trust
Securities or otherwise adversely affect the amount of any Distribution required
to be made in respect of the Trust Securities as of a specified date or (ii)
restrict the right of a holder of Trust Securities to institute suit for the
enforcement of any such payment on or after such date.

                  8. Pro Rata.

                  A reference in these terms of the Securities to any payment,
distribution or treatment as being "Pro Rata" shall mean pro rata to each Holder
of Securities according to the aggregate Liquidation Amount of the Securities
held by the relevant Holder in relation to the aggregate Liquidation Amount of
all Securities outstanding unless, in relation to a payment, an Event of Default
under the Declaration has occurred and is continuing, in which case any funds
available to make such payment shall be paid first to each Holder of the Capital
Securities pro rata according to the aggregate Liquidation Amount of Capital
Securities held by the relevant Holder relative to the aggregate Liquidation
Amount of all Capital Securities outstanding, and only after satisfaction of all
amounts owed to the Holders of the Capital Securities, to each Holder of Common
Securities pro rata according to the aggregate liquidation amount of Common
Securities held by the relevant Holder relative to the aggregate Liquidation
Amount of all Common Securities outstanding.

                  9. Ranking.


                  The Capital Securities rank pari passu with the Common
Securities and payment thereon shall be made Pro Rata with the Common
Securities, except that, if an Event of Default under the Declaration occurs and
is continuing, no payments in respect of Distributions on, or payments upon
liquidation, redemption or otherwise with respect to, the Common Securities
shall be made until the Holders of the Capital Securities shall be paid in full
the Distributions, Redemption Price, Liquidation Distribution and other payments
to which they are entitled at such time.

                  10. Acceptance of Securities Guarantee and Indenture.

                  Each Holder of Capital Securities and Common Securities, by
the acceptance thereof, agrees to the provisions


                                      I-16

<PAGE>


of the Capital Securities Guarantee and the Common Securities Guarantee,
respectively, including the subordination provisions therein and to the
provisions of the Indenture.

                  11. No Preemptive Rights.

                  The Holders of the Securities shall have no preemptive rights
to subscribe for any additional securities.

                  12. Miscellaneous.

                  These terms constitute a part of the Declaration.

                  The Sponsor will provide a copy of the Declaration, the
Capital Securities Guarantee or the Common Securities Guarantee (as may be
appropriate) and the Indenture (including any supplemental indenture) to a
Holder without charge on written request to the Sponsor at its principal place
of business.

                          [FORM OF REVERSE OF SECURITY]

                           Distributions payable on each Capital Security
will be fixed at a rate per annum of 8.71% (the "Coupon Rate") of the
Liquidation Amount of $1,000 per Capital Security, such rate being the rate of
interest payable on the Debentures to be held by the Property Trustee.
Distributions in arrears for more than one semi-annual period will bear interest
thereon compounded semi-annually at the Coupon Rate (to the extent permitted by
applicable law). Pursuant to the Registration Rights Agreement, in certain
limited circumstances the Debenture Issuer will be required to pay Liquidated
Damages (as defined in the Registration Rights Agreement) with respect to the
Debentures. The term "Distributions", as used herein, includes such cash
distributions and any such interest and such Liquidated Damages payable unless
otherwise stated. A Distribution is payable only to the extent that payments are
made in respect of the Debentures held by the Property Trustee and to the extent
the Property Trustee has funds on hand legally available therefor.

                  Distributions on the Capital Securities will be cumulative,
will accumulate from the most recent date to which Distributions have been paid
or, if any Distributions have been paid, from January 13, 1997 and will be
payable semi-annually in arrears, on January 1 and July 1 of each year,
commencing on July 1, 1997, except as otherwise described below and in the
Declaration. Distributions will be computed on the basis of a 360-day year
consisting of twelve 30-day months and, for any period less than a full calendar
month, the number of days elapsed in such month. As long as no Event of Default
has occurred and is continuing under the Indenture, the Debenture Issuer has the
right under the Indenture to defer payments of interest by extending the
interest payment period at any time and from time to time on the Debentures for
a period not exceeding 10 consecutive calendar semi-annual periods, including
the first such semi-annual period during such extension period (each an
"Extension Period"), provided that no Extension Period shall extend beyond the
Maturity Date of the Debentures. As a consequence of such deferral,
Distributions will also be deferred. Despite such deferral, semi-annual
Distributions will continue to accumulate with interest thereon (to the extent
permitted by applicable law, but not at a rate exceeding the rate of interest
then accruing on the Debentures) at the Coupon Rate





                                      A1-7

<PAGE>






compounded semi-annually during any such Extension Period. Prior to the
termination of any such Extension Period, the Debenture Issuer may further defer
payments of interest by further extending such Extension Period; provided that
such Extension Period, together with all such previous and further extensions
within such Extension Period, may not exceed 10 consecutive semi-annual periods,
including the first semi-annual period during such Extension Period, or extend
beyond the Maturity Date of the Debentures. Payments of Distributions that have
accumulated but not been paid during any Extension Period will be payable to
Holders as they appear on the books and records of the Trust on the records of
the Trust on the record date for the first scheduled Distribution payment date
following the expiration of such first record date after the end of the
Extension Period. Upon the expiration of any Extension Period and the payment of
all amounts then due, the Debenture Issuer may commence a new Extension Period,
subject to the above requirements.

                  Subject to certain conditions set forth in the Declaration and
the Indenture, the Property Trustee shall, at the direction of the Sponsor, at
any time liquidate the Trust and cause the Debentures to be distributed to the
holders of the Securities in liquidation of the Trust or, simultaneous with any
redemption of the Debentures, cause a Like Amount of the Securities to be
redeemed by the Trust.

                  The Capital Securities shall be redeemable as provided in the
Declaration upon the maturity or prepayment of the Debentures. The maturity date
of the Debentures is January 1, 2046, which date is subject to advancement as
described in the next sentence. If a Tax Event occurs, then the Sponsor will
have the right (i) prior to the termination of the Trust, to advance the
Maturity Date of the Debentures to the minimum extent required, but not to a
date earlier than twenty years from January 13, 1997 (the "Issue Date"), or (ii)
to terminate the Trust (if not previously terminated) and advance the Maturity
Date of the Debentures to the minimum extent required, but not to a date earlier
than forty years from the Issue Date, in each case such that, in the written
opinion of counsel experienced in such matters delivered to the Sponsor, after
advancing the Maturity Date, interest paid on the Debentures shall be deductible
for United States federal income tax purposes.

                          [FORM OF REVERSE OF SECURITY]

                  Distributions payable on each Common Security will be fixed at
a rate per annum of 8.71% (the "Coupon Rate") of the liquidation amount of
$1,000 per Common Security, such rate being the rate of interest payable on the
Debentures to be held by the Property Trustee. Distributions in arrears for more
than one semi-annual period will bear interest thereon compounded semiannually
at the Coupon Rate (to the extent permitted by applicable law). Pursuant to the
Registration Rights Agreement, in certain limited circumstances the Debenture
Issuer will be required to pay Liquidated Damages (as defined in the
Registration Rights Agreement) with respect to the Debentures. The term
"Distributions", as used herein, includes such cash distributions and any such
interest and such Liquidated Damages payable unless otherwise stated. A
Distribution is payable only to the extent that payments are made in respect of
the Debentures held by the Property Trustee and to the extent the Property
Trustee has funds available therefor.

                  Distributions on the Common Securities will be cumulative,
will accrue from the most recent date to which Distributions have been paid or,
if no Distributions have been paid, from January 13, 1997 and will be payable
semi-annually in arrears, on January 1 and July 1 of each year, commencing on
July 1, 1997, except as otherwise described below and in the Declaration.
Distributions will be computed on the basis of a 360-day year consisting of
twelve 30 day months and, for any period less than a full calendar month, the
number of days elapsed in such month. As long as no Event of Default has
occurred and is continuing under the Indenture, the Debenture Issuer has the
right under the Indenture to defer payments of interest by extending the
interest payment period at any time and from time to time on the Debentures for
a period not exceeding 10 consecutive calendar semi-annual periods, including
the first such semi-annual period during such extension period (each an
"Extension Period"), provided that no Extension Period shall extend beyond the
Maturity Date of the Debentures. As a consequence of such deferral,
Distributions will also be deferred. Despite such deferral, Distributions will
continue to accumulate with interest thereon (to the extent permitted by
applicable law, but not at a rate exceeding the rate of interest then accruing
on the Debentures) at the Coupon Rate compounded



                                      A2-5

<PAGE>


semi-annually during any such Extension Period. Prior to the termination of any
such Extension Period, the Debenture Issuer may further defer payments of
interest by further extending such Extension Period; provided that such
Extension Period, together with all such previous and further extensions within
such Extension Period, may not exceed 10 consecutive semi-annual periods,
including the first semi-annual period during such Extension Period, or extend
beyond the Maturity Date of the Debentures. Payments of Distributions that have
accumulated will be payable to Holders as they appear on the books and records
of the Trust on the record date for the first Distribution Date following the
expiration of such Extension Period. Upon the expiration of any Extension Period
and the payment of all amounts then due, the Debenture Issuer may commence a new
Extension Period, subject to the above requirements.

                  Subject to certain conditions set forth in the Declaration and
the Indenture, the Property Trustee shall, at the direction of the Sponsor, at
any time liquidate the Trust and cause the Debentures to be distributed to the
holders to the Securities in liquidation of the Trust or, simultaneous with any
redemption of the Debentures, cause a Like Amount of the Securities to be
redeemed by the Trust.

                  The Common Securities shall be redeemable as provided in the
Declaration.

         no  obligation  to exercise any of the rights or powers vested in it by

         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

         resolution,   certificate,   statement,  instrument,  opinion,  report,
         notice,  request,  direction,  consent,  order, bond, debenture,  note,
         other  evidence of  indebtedness  or other paper or  document,  but the

         further inquiry or  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

         Trustee or its agents  hereunder shall bind the Holders of the Series B
         Capital  Securities,  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  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  in  conclusively  relying  on or  acting in
         accordance with such instructions.

                  (xi) The Capital  Securities  Guarantee  Trustee  shall not be
         liable for any action taken,  suffered, or omitted to be taken by it in
         good faith,  without  negligence,  and reasonably  believed by it to be
         authorized 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.

of amounts  theretofore paid by the Issuer),  as and when due, 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

                  (g) the consummation of the Exchange Offer; or

                  (h) any other  circumstance  whatsoever  that might  otherwise

Trustee under this Series B Capital Securities Guarantee.

                                       8

<PAGE>

Business Day of the Exchange Period, by sending to the institution specified in

exchange, and a statement that such Holder is withdrawing his election to have
such Securities exchanged;

         (v) notify each Holder that any Security not tendered by such Holder in
the Exchange Offer will remain outstanding and continue to accrue interest or

under this Agreement (except in the case of the Initial Purchasers and

         (vi) otherwise comply in all respects with all applicable laws relating
to the Exchange Offer.

                  If any Initial Purchaser determines upon advice of its outside
counsel that it is not eligible to participate in the Exchange Offer with
respect to the exchange of Securities constituting any portion of an unsold
allotment in the initial distribution, as soon as practicable upon receipt by
the Company and the Trust of a written request from such Initial Purchaser, the
Company and the Trust, as applicable, shall issue and deliver to such Initial
Purchaser in exchange (the "Private Exchange") for the Securities held by such
Initial Purchaser, a like liquidation amount of Capital Securities of the Trust,

the Indenture, the Declaration or the Guarantee (which provides that the
Exchange Securities will not be subject to the transfer restrictions set forth
in the Indenture or the Declaration, as applicable, and that the Exchange
Securities, the Private Exchange Securities and the Securities will vote and
consent together on all matters as one class and that neither the Exchange
Securities, the Private Exchange Securities nor the Securities will have the
right to vote or consent as a separate class on any matter). The Private

                                       9
<PAGE>


Exchange Securities shall be of the same series as the Exchange Securities and
the Company and the Trust will seek to cause the CUSIP Service Bureau to issue
the same CUSIP Numbers for the Private Exchange Securities as for the Exchange
Securities issued pursuant to the Exchange Offer.

                  As soon as practicable after the close of the Exchange Offer
and, if applicable, the Private Exchange, the Company and the Trust, as the case
requires, shall:

         (i)      accept for exchange all Securities or portions thereof
tendered and not validly withdrawn pursuant to the Exchange Offer
or the Private Exchange;

         (ii)     deliver, or cause to be delivered, to the applicable
Trustee for cancellation all Securities or portions thereof so
accepted for exchange by the Company; and

         (iii)    issue, and cause the applicable Trustee under the Indenture,
the Declaration or the Guarantee, as applicable, to promptly authenticate and
deliver to each Holder, new Exchange Securities or Private Exchange Securities,
as applicable, equal in principal amount to the principal amount of the
Subordinated Debentures or equal in liquidation amount to the liquidation amount
to the Capital Securities (together with the guarantee thereof) as are
surrendered by such Holder.

                  Distributions on each Exchange Capital Security and interest
on each Exchange Debenture and Private Exchange Security issued pursuant to the
Registered Exchange Offer and in the Private Exchange will accrue from the last
date on which a Distribution or interest was paid on the Capital Security or the
Subordinated Debenture surrendered in exchange therefore or, if no Distribution
or interest has been paid on such Capital Security or Subordinated Debenture,
from the Issue Date. To the extent not prohibited by any law or applicable
interpretation of the staff of the SEC, the Company and the Trust shall use
their best efforts to complete the Exchange Offer as provided above, and shall
comply with the applicable requirements of the Securities Act, the Exchange Act
and other applicable laws in connection with the Exchange Offer. The Exchange
Offer shall not

                                       10

<PAGE>

be subject to any conditions, other than that the Exchange Offer does not
violate applicable law or any applicable interpretation of the staff of the SEC.
Each Holder of Registrable Securities who wishes to exchange such Registrable
Securities for Exchange Securities in the Exchange Offer will be required to
make certain customary representations in connection therewith, including, in
the case of any Holder of Capital Securities, representations that (i) it is not
an affiliate of the Trust or the Company, (ii) the Exchange Securities to be
received by it were acquired in the ordinary course of its business and (iii) at
the time of the Exchange Offer, it has no arrangement with any person to
participate in the distribution (within the meaning of the Securities Act) of
the Exchange Capital Securities. The Company and the Trust shall inform the
Initial Purchasers, after consultation with the Trustee, of the names and
addresses of the Holders to whom the Exchange Offer is made, and the Initial
Purchasers shall have the right to contact such Holders and otherwise facilitate
the tender of Registrable Securities in the Exchange Offer.

                  Upon consummation of the Exchange Offer in accordance with
this Section 2(a), the provisions of this Agreement shall continue to apply,
mutatis mutandis, solely with respect to Registrable Securities that are Private
Exchange Securities and Exchange Securities held by Participating
Broker-Dealers, and the Company and the Trust shall have no further obligation
to register the Registrable Securities (other than Private Exchange Securities)
pursuant to Section 2(b) of this Agreement.

                  (b) Shelf Registration. In the event that (i) the Company, the
Trust or the Majority Holders reasonably determine, after conferring with
counsel (which may be in-house counsel), that the Exchange Offer Registration
provided in Section 2(a) above is not available because of any change in law or
in currently prevailing interpretations of the staff of the SEC, (ii) the
Exchange Offer Registration Statement is not declared effective within 180 days
of January 8, 1997 or (iii) upon the request of any Initial Purchaser with
respect to any Registrable Securities held by it, if such Initial Purchaser is
not permitted, in the reasonable opinion of Brown & Wood LLP, pursuant to
applicable law or applicable interpretations of the

                                       11

<PAGE>

staff of the SEC, to participate in the Exchange Offer and thereby receive
securities that are freely tradeable without restriction under the Securities
Act and applicable blue sky or state securities laws (any of the events
specified in (i)-(iii) being a "Shelf Registration Event" and the date of
occurrence thereof, the "Shelf Registration Event Date"), the Company and the
Trust shall, at their cost, use their reasonable best efforts to cause to be
filed as promptly as practicable after such Shelf Registration Event Date, as
the case may be, and, in any event, within 45 days after such Shelf Registration
Event Date (which shall be no earlier than 75 days after the Closing Time), a
Shelf Registration Statement providing for the sale by the Holders of all of the
Registrable Securities, and shall use their reasonable best efforts to have such
Shelf Registration Statement declared effective by the SEC as soon as
practicable. No Holder of Registrable Securities shall be entitled to include
any of its Registrable Securities in any Shelf Registration pursuant to this
Agreement unless and until such Holder agrees in writing to be bound by all of
the provisions of this Agreement applicable to such Holder and furnishes to the
Company and the Trust in writing, within 15 days after receipt of a request
therefor, such information as the Company and the Trust may, after conferring
with counsel with regard to information relating to Holders that would be
required by the SEC to be included in such Shelf Registration Statement or
Prospectus included therein, reasonably request for inclusion in any Shelf
Registration Statement or Prospectus included therein. Each Holder as to which
any Shelf Registration is being effected agrees to furnish to the Company and
the Trust all information with respect to such Holder necessary to make the
information previously furnished to the Company by such Holder not materially
misleading.

                  The Company and the Trust agree to use their reasonable best
efforts to keep the Shelf Registration Statement continuously effective for the
Rule 144(k) Period (subject to extension pursuant to the last paragraph of
Section 3 hereof) or for such shorter period which will terminate when all of
the Registrable Securities covered by the Shelf Registration Statement have been
sold pursuant to the Shelf Registration Statement or cease to be outstanding
(the "Effectiveness Period"). The Company and the Trust shall not permit any

                                       12

<PAGE>


securities other than Registrable Securities to be included in the Shelf
Registration. The Company and the Trust will, in the event a Shelf Registration
Statement is declared effective, provide to each Holder a reasonable number of
copies of the Prospectus which is a part of the Shelf Registration Statement,
notify each such Holder when the Shelf Registration has become effective and use
its best efforts to take certain other actions as are required to permit certain
unrestricted resales of the Registrable Securities. The Company and the Trust
further agree, if necessary, to supplement or amend the Shelf Registration
Statement, if required by the rules, regulations or instructions applicable to
the registration form used by the Company for such Shelf Registration Statement
or by the Securities Act or by any other rules and regulations thereunder for
shelf registrations, and the Company and the Trust agree to furnish to the
Holders of Registrable Securities copies of any such supplement or amendment
promptly after its being used or filed with the SEC.

                  (c) Expenses. The Company shall pay all Registration Expenses
in connection with the registration pursuant to Section 2(a) or 2(b) hereof and
will reimburse the Initial Purchasers for the reasonable fees and disbursements
of Brown & Wood LLP, counsel for the Initial Purchasers, incurred in connection
with the Exchange Offer and, if applicable, the Private Exchange Offer, and
either Brown & Wood LLP or any one other counsel designated in writing by the
Majority Holders to act as counsel for the Holders of the Registrable Securities
in connection with a Shelf Registration Statement, which other counsel shall be
reasonably satisfactory to the Company. Except as provided herein, each Holder
shall pay all expenses of its counsel, underwriting discounts and commissions
and transfer taxes if any, relating to the sale or disposition of such Holder's
Registrable Securities pursuant to the Shelf Registration Statement.

                  (d) Effective Registration Statement. An Exchange Offer
Registration Statement pursuant to Section 2(a) hereof or a Shelf Registration
Statement pursuant to Section 2(b) hereof will not be deemed to have become
effective unless it has been declared effective by the SEC; provided, however,
that if, after it has been declared effective, the offering of Registrable
Securities pursuant to a Shelf Registration Statement is

                                       13

<PAGE>

interfered with by any stop order, injunction or other order or requirement of
the SEC or any other governmental agency or court, such Registration Statement
will be deemed not to have been effective during the period of such
interference, until the offering of Registrable Securities pursuant to such
Registration Statement may legally resume. The Company and the Trust will be
deemed not to have used their best efforts to cause the Exchange Offer
Registration Statement or the Shelf Registration Statement, as the case may be,
to become, or to remain, effective during the requisite period if either of them
voluntarily take any action that would result in any such Registration Statement
not being declared effective or in the Holders of Registrable Securities covered
thereby not being able to exchange or offer and sell such Registrable Securities
during that period unless such action is required by applicable law.

                  (e)  Liquidated Damages.  In the event that (i) (A)
neither the Exchange Offer Registration Statement nor a Shelf Registration
Statement is filed with the SEC on or prior to the 150th day after January 8,
1997 or (B) notwithstanding that the Company and the Trust have consummated or
will consummate an Exchange Offer, the Company and the Trust are required to
file a Shelf Registration Statement and such Shelf Registration Statement is not
filed on or prior to the date required by Section 2(b) hereof, then commencing
on the day after the applicable required filing date, additional interest shall
accrue on the principal amount of the Subordinated Debentures, and additional
Distributions shall accumulate on the liquidation amount of the Capital
Securities, each at a rate of 0.25% per annum; or

         (ii) (A) neither the Exchange Offer Registration Statement nor a Shelf
Registration Statement is declared effective by the SEC on or prior to the 30th
day after the applicable required filing date or (B) notwithstanding that the
Company and the Trust have consummated an Exchange Offer, the Company and the
Trust are required to file a Shelf Registration Statement and such Shelf
Registration Statement is not declared effective by the SEC on or prior to the
30th day after the date such Shelf Registration Statement was required to be
filed, then, commencing on the 31st day after the applicable required filing
date, additional

                                       14

<PAGE>

interest shall accrue on the principal amount of the Subordinated Debentures and
additional Distributions shall accumulate on the liquidation amount of the
Capital Securities, each at a rate of 0.25% per annum; or

         (iii) (A) the Trust has not exchanged Exchange Capital Securities for
all Capital Securities or the Company has not exchanged Exchange Guarantees or
Exchange Subordinated Debentures for all Guarantees or Subordinated Debentures
validly tendered, in accordance with the terms of the Exchange Offer on or prior
to the 30th day after the date on which the Exchange Offer Registration
Statement was declared effective or (B) if applicable, the Shelf Registration
Statement has been declared effective and such Shelf Registration Statement
ceases to be effective at any time prior to the expiration of the Rule 144(k)
Period (other than after such time as all Capital Securities have been disposed
of thereunder or otherwise cease to be Registrable Securities), then additional
interest shall accrue on the principal amount of Subordinated Debentures, and
additional Distributions shall accumulate on the liquidation amount of the
Capital Securities, each at a rate of 0.25% per annum commencing on (x) the 31st
day after such effective date, in the case of (A) above, or (y) the day such
Shelf Registration Statement ceases to be effective in the case of (B) above;

provided, however, that neither the additional interest rate on the Subordinated
Debentures, nor the additional distribution rate on the liquidation amount of
the Capital Securities, may exceed in the aggregate 0.25% per annum; provided,
further, however, that (1) upon the filing of the Exchange Offer Registration
Statement or a Shelf Registration Statement (in the case of clause (i) above),
(2) upon the effectiveness of the Exchange Offer Registration Statement or a
Shelf Registration Statement (in the case of clause (ii) above), or (3) upon the
exchange of Exchange Capital Securities, Exchange Guarantees and Exchange
Subordinated Debentures for all Capital Securities, Guarantees and Subordinated
Debentures tendered (in the case of clause (iii)(A) above), or upon the
effectiveness of the Shelf Registration Statement which had ceased to remain
effective (in the case of clause (iii)(B) above), additional interest on the
Subordinated Debentures, and additional distributions on the

                                       15

<PAGE>


liquidation amount of the Capital Securities as a result of such clause (or the
relevant subclause thereof), as the case may be, shall cease to accrue or
accumulate, as the case may be.

         Any amounts of additional interest and additional Distributions due
pursuant to Section 2(e)(i), (ii) or (iii) above (the "Liquidated Damages") will
be payable in cash on January 1 and July 1 of each year to the holders of record
on the relevant record dates for the payment of interest and Distributions
pursuant to the Indenture and the Declaration respectively.

                  (f) Specific Enforcement. Without limiting the remedies
available to the Holders, the Company and the Trust acknowledge that any failure
by the Company or the Trust to comply with its obligations under Section 2(a)
and Section 2(b) hereof may result in material irreparable injury to the Holders
for which there is no adequate remedy at law, that it would not be possible to
measure damages for such injuries precisely and that, in the event of any such
failure, any Holder may obtain such relief as may be required to specifically
enforce the Company's and the Trust's obligations under Section 2(a) and Section
2(b) hereof.

                  3.  Registration Procedures.  In connection with the
obligations of the Company and the Trust with respect to the Registration
Statements pursuant to Sections 2(a) and 2(b) hereof, the Company and the Trust
shall use their reasonable best efforts to:

                  (a) prepare and file with the SEC a Registration Statement or
         Registration Statements as prescribed by Sections 2(a) and 2(b) hereof
         within the relevant time period specified in Section 2 hereof on the
         appropriate form under the Securities Act, which form (i) shall be
         selected by the Company and the Trust, (ii) shall, in the case of a
         Shelf Registration, be available for the sale of the
         Registrable Securities by the selling Holders thereof and (iii) shall
         comply as to form in all material respects with the requirements of the
         applicable form and include all financial statements required by the
         SEC to be filed

                                       16

<PAGE>

         therewith; and use its best efforts to cause such Registration
         Statement to become effective and remain effective in accordance with
         Section 2 hereof; provided, however, that if (1) such filing is
         pursuant to Section 2(b), or (2) a Prospectus contained in an Exchange
         Offer Registration Statement filed pursuant to Section 2(a) is required
         to be delivered under the Securities Act by any Participating
         Broker-Dealer who seeks to sell Exchange Securities, before filing any
         Registration Statement or Prospectus or any amendments or supplements
         thereto, the Company and the Trust shall furnish to and afford the
         Holders of the Registrable Securities and each such Participating
         Broker-Dealer, as the case may be, covered by such Registration
         Statement, their counsel and the managing underwriters, if any, a
         reasonable opportunity to review copies of all such documents
         (including copies of any documents to be incorporated by reference
         therein and all exhibits thereto) proposed to be filed. The Company and
         the Trust shall not file any Registration Statement or Prospectus or
         any amendments or supplements thereto in respect of which the Holders
         must be afforded an opportunity to review prior to the filing of such
         document if the Majority Holders or such Participating Broker-Dealer,
         as the case may be, their counsel or the managing underwriters, if any,
         shall reasonably object;

                  (b) prepare and file with the SEC such amendments and
         post-effective amendments to each Registration Statement as may be
         necessary to keep such Registration Statement effective for the
         Effectiveness Period or the Applicable Period, as the case may be; and
         cause each Prospectus to be supplemented, if so determined by the
         Company or the Trust or requested by the SEC, by any required
         prospectus supplement and as so supplemented to be filed pursuant to
         Rule 424 (or any similar provision then in force) under the Securities
         Act, and comply with the provisions of the Securities Act, the Exchange
         Act and the rules and regulations promulgated thereunder applicable to
         it with respect to the disposition of all securities covered by each
         Registration Statement during the Effectiveness Period or the
         Applicable Period, as the case may be, in accordance


                                       17

<PAGE>


         with the intended method or methods of distribution by the selling
         Holders thereof described in this Agreement (including sales by any
         Participating Broker-Dealer);

                  (c) in the case of a Shelf Registration, (i) notify each
         Holder of Registrable Securities included in the Shelf Registration
         Statement, at least three Business Days prior to filing, that a Shelf
         Registration Statement with respect to the Registrable Securities is
         being filed and advising such Holder that the distribution of
         Registrable Securities will be made in accordance with the method
         selected by the Majority Holders; and (ii) furnish to each Holder of
         Registrable Securities included in the Shelf Registration Statement and
         to each underwriter of an underwritten offering of Registrable
         Securities, if any, without charge, as many copies of each Prospectus,
         including each preliminary Prospectus, and any amendment or supplement
         thereto and such other documents as such Holder or underwriter may
         reasonably request, in order to facilitate the public sale or other
         disposition of the Registrable Securities; and (iii) consent to the use
         of the Prospectus or any amendment or supplement thereto by each of the
         selling Holders of Registrable Securities included in the Shelf
         Registration Statement in connection with the offering and sale of the
         Registrable Securities covered by the Prospectus or any amendment or
         supplement thereto;

                  (d) in the case of a Shelf Registration, use their reasonable
         best efforts to register or qualify the Registrable Securities under
         all applicable state securities or "blue sky" laws of such
         jurisdictions by the time the applicable Registration Statement is
         declared effective by the SEC as any Holder of Registrable Securities
         covered by a Registration Statement and each underwriter of an
         underwritten offering of Registrable Securities shall reasonably
         request in writing in advance of such date of effectiveness, and do any
         and all other acts and things which may be reasonably necessary or
         advisable to enable such Holder and underwriter to consummate the
         disposition in each such jurisdiction of such Registrable Securities
         owned by such Holder; provided, however, that the Company and the

                                       18

<PAGE>

         Trust shall not be required to (i) qualify as a foreign corporation or
         as a dealer in securities in any jurisdiction where it would not
         otherwise be required to qualify but for this Section 3(d); (ii) file
         any general consent to service of process in any jurisdiction where it
         would not otherwise be subject to such service of process or (iii)
         subject itself to taxation in any such jurisdiction if it is not then
         so subject;

                  (e) in the case of (1) a Shelf Registration or (2)
         Participating Broker-Dealers from whom the Company or the Trust has
         received prior written notice that they will be utilizing the
         Prospectus contained in the Exchange Offer Registration Statement as
         provided in Section 3(t) hereof, are seeking to sell Exchange
         Securities and are required to deliver Prospectuses, notify each Holder
         of Registrable Securities, or such Participating Broker-Dealers, as the
         case may be, their counsel and the managing underwriters, if any,
         promptly and promptly confirm such notice in writing (i) when a
         Registration Statement has become effective and when any post-effective
         amendments and supplements thereto become effective, (ii) of any
         request by the SEC or any state securities authority for amendments and
         supplements to a Registration Statement or Prospectus or for additional
         information after the Registration Statement has become effective,
         (iii) of the issuance by the SEC or any state securities authority of
         any stop order suspending the effectiveness of a Registration Statement
         or the qualification of the Registrable Securities or the Exchange
         Securities to be offered or sold by any Participating Broker-Dealer in
         any jurisdiction described in paragraph 3(d) hereof or the initiation
         of any proceedings for that purpose, (iv) in the case of a Shelf
         Registration, if, between the effective date of a Registration
         Statement and the closing of any sale of Registrable Securities covered
         thereby, the representations and warranties of the Company and the
         Trust contained in any purchase agreement, securities sales agreement
         or other similar agreement, if any cease to be true and correct in all
         material respects, and (v) of the happening of any event or the failure
         of any event to occur or the discovery of any facts or otherwise,

                                       19
<PAGE>

         during the Effectiveness Period which makes any statement made in such
         Registration Statement or the related Prospectus untrue in any material
         respect or which causes such Registration Statement or Prospectus to
         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, and (vi) the Company and the Trust's reasonable
         determination that a post-effective amendment to the Registration
         Statement would be appropriate;

                  (f)  make every reasonable effort to obtain the
         withdrawal of any order suspending the effectiveness of a
         Registration Statement at the earliest possible moment;

                  (g) in the case of a Shelf Registration, furnish to each
         Holder of Registrable Securities included within the coverage of such
         Shelf Registration Statement, without charge, at least one conformed
         copy of each Registration Statement relating to such Shelf Registration
         and any post-effective amendment thereto (without documents
         incorporated therein by reference or exhibits thereto, unless
         requested);

                  (h) in the case of a Shelf Registration, cooperate with the
         selling Holders of Registrable Securities to facilitate the timely
         preparation and delivery of certificates representing Registrable
         Securities to be sold and not bearing any restrictive legends and in
         such denominations (consistent with the provisions of the Indenture and
         the Declaration) and registered in such names as the selling Holders or
         the underwriters may reasonably request at least two Business Days
         prior to the closing of any sale of Registrable Securities pursuant to
         such Shelf Registration Statement;

                  (i) in the case of a Shelf Registration or an Exchange Offer
         Registration, upon the occurrence of any circumstance contemplated by
         Section 3(e)(ii), 3(e)(iii), 3(e)(v) or 3(e)(vi) hereof, use its best
         efforts to prepare a supplement or post-effective amendment to a
         Registration Statement or the related Prospectus or any document

                                       20
<PAGE>

         incorporated therein by reference or file any other required document
         so that, as thereafter delivered to the purchasers of the Registrable
         Securities, such Prospectus 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; and to notify each Holder to suspend use of
         the Prospectus as promptly as practicable after the occurrence of such
         an event, and each Holder hereby agrees to suspend use of the
         Prospectus until the Company has amended or supplemented the Prospectus
         to correct such misstatement or omission;

                  (j) in the case of a Shelf Registration, a reasonable time
         prior to the filing of any document which is to be incorporated by
         reference into a Registration Statement or a Prospectus after the
         initial filing of a Registration Statement, provide a reasonable number
         of copies of such document to the Holders; and make such of the
         representatives of the Company and the Trust as shall be reasonably
         requested by the Holders of Registrable Securities or the Initial
         Purchasers on behalf of such Holders available for discussion of such
         document;

                  (k) obtain a CUSIP number for all Exchange Capital Securities
         and the Capital Securities (and if the Trust has made a distribution of
         the Subordinated Debentures to the Holders of the Capital Securities,
         the Subordinated Debentures or the Exchange Subordinated Debentures) as
         the case may be, not later than the effective date of a Registration
         Statement, and provide the Trustee with printed certificates for the
         Exchange Securities or the Registrable Securities, as the case may be,
         in a form eligible for deposit with the Depositary;

                  (l) cause the Indenture, the Declaration, the Guarantee and
         the Exchange Guarantee to be qualified under the Trust Indenture Act of
         1939 (the "TIA") in connection with the registration of the Exchange
         Securities or Registrable Securities, as the case may be, and effect
         such changes to such documents as may be required for them to be

                                       21

<PAGE>

         so qualified in accordance with the terms of the TIA and execute, and
         use its best efforts to cause the relevant trustee to execute, all

         Registration Statement and the managing underwriters or agents) with
         respect to all parties to be indemnified pursuant to said Section
         (including, without limitation, such underwriters and selling Holders).
         The above shall be done at each closing under such underwriting

         2(b) or (2) a Prospectus contained in an Exchange Offer Registration
         Statement filed pursuant to Section 2(a) is required to be delivered
         under the Securities Act by any Participating Broker-Dealer who seeks

         (collectively, the "Records") as shall be reasonably necessary to
         enable them to exercise any applicable due diligence responsibilities,
         and cause the officers, directors and employees of the Trust, the
         Company and its subsidiaries to supply all relevant information in each
         case reasonably requested by any such Inspector in connection with such
         Registration Statement provided, however, that the foregoing inspection
         and information gathering shall be coordinated on behalf of the
         Purchasers by DLJ and on behalf of the other parties, by one counsel
         designated by DLJ and on behalf of such other parties as described in
         Section 2(c) hereof. Records which the Company and the Trust determine,
         in good faith, to be confidential and any records which it notifies the
         Inspectors are confidential shall not be disclosed by the Inspectors
         unless (i) the disclosure of such Records is necessary to avoid or
         correct a material misstatement or omission in such Registration
         Statement, (ii) the release of such Records is ordered pursuant to a
         subpoena or other order from a court of competent jurisdiction or is

         the end of any 12-month period (or 90 days after the end of any
         12-month period if such period is a fiscal year) (i) commencing at the
         end of any fiscal quarter in which Registrable Securities are sold to

         the first day of the first fiscal quarter of the Company after the
         effective date of a Registration Statement, which statements shall
         cover said 12-month periods;

         Exchange, if requested by a Trustee, obtain an opinion of counsel to
         the Company addressed to the Trustee for the benefit of all Holders of

         Private Exchange, as the case may be, and which includes an opinion
         that (i) the Company and the Trust, as the case requires, has duly
         authorized, executed and delivered the Exchange Securities and Private
         Exchange Securities, and (ii) each of the Exchange Securities or the
         Private Exchange Securities, as the case may be, constitute a legal,
         valid and binding obligation of the Company or the Trust, as the case
         requires, enforceable against the Company or the Trust, as the case
         requires, in accordance with its respective terms (in each case, with
         customary exceptions);

                  (q) if an Exchange Offer or a Private Exchange is to be
         consummated, upon delivery of the Registrable Securities by Holders to
         the Company or the Trust, as applicable (or to such other Person as
         directed by the Company or the Trust, respectively), in exchange for
         the Exchange Securities or the Private Exchange Securities, as the case
         may be, the Company or the Trust, as applicable, shall mark, or cause
         to be marked, on such Registrable Securities delivered by such Holders
         that such Registrable Securities are being cancelled in exchange for
         the Exchange Securities or the Private Exchange Securities, as the case

         shall such Registrable Securities be marked as paid or otherwise
         satisfied;

                  (r) cooperate with each seller of Registrable Securities
         covered by any Registration Statement and each underwriter, if any,
         participating in the disposition of such Registrable Securities and
         their respective counsel in connection with any filings required to be
         made with the NASD;

                  (s) use its best efforts to take all other steps necessary to
         effect the registration of the Registrable Securities covered by a
         Registration Statement contemplated hereby;

                  (t) (A) in the case of the Exchange Offer Registration
         Statement (i) include in the Exchange Offer Registration Statement a
         section entitled "Plan of Distribution, which section shall be
         reasonably acceptable to the Initial Purchasers or another
         representative of the Participating Broker-Dealers, and which shall
         contain a summary statement of the positions taken or policies made by
         the staff of the SEC with respect to the potential "underwriter" status
         of any broker-dealer (a "Participating Broker-Dealer") that holds
         Registrable Securities acquired for its own account as a result of
         market-making activities or other trading activities and that will be
         the beneficial owner (as defined in Rule 13d-3 under the Exchange Act)
         of Exchange Securities to be received by such broker-dealer in the
         Exchange Offer, whether such positions or policies have been publicly
         disseminated by the staff of the SEC or such positions or policies, in
         the reasonable judgment of the Initial Purchasers or such other
         representative, represent the prevailing views of the staff of the SEC,
         including a statement that any such broker-dealer who receives Exchange
         Securities for Registrable Securities pursuant to the Exchange Offer
         may be deemed a statutory underwriter and must deliver a prospectus
         meeting the requirements of the Securities Act in connection with any
         resale of such Exchange Securities, (ii) furnish to each Participating
         Broker-Dealer who has delivered to the Company the notice

                                       26

<PAGE>

         referred to in Section 3(e), without charge, as many copies of each
         Prospectus included in the Exchange Offer Registration Statement,
         including any preliminary prospectus, and any amendment or supplement
         thereto, as such Participating Broker-Dealer may reasonably request
         (each of the Company and the Trust hereby consents to the use of the
         Prospectus forming part of the Exchange Offer Registration Statement or
         any amendment or supplement thereto by any Person subject to the
         prospectus delivery requirements of the Securities Act, including all
         Participating Broker-Dealers, in connection with the sale or transfer
         of the Exchange Securities covered by the Prospectus or any amendment
         or supplement thereto), (iii) use its best efforts to keep the Exchange
         Offer Registration Statement effective and to amend and supplement the
         Prospectus contained therein in order to permit such Prospectus to be
         lawfully delivered by all Persons subject to the prospectus delivery
         requirements of the Securities Act for such period of time as such
         Persons must comply with such requirements under the Securities Act and
         applicable rules and regulations in order to resell the Exchange
         Securities; provided, however, that such period shall not be required
         to exceed 90 days (or such longer period if extended pursuant to the
         last sentence of Section 3 hereof) (the "Applicable Period"), and (iv)
         include in the transmittal letter or similar documentation to be
         executed by an exchange offeree in order to participate in the Exchange
         Offer (x) the following provision:

                  "If the exchange offeree is a broker-dealer holding
                  Registrable Securities acquired for its own account as a
                  result of market-making activities or other trading
                  activities, it will deliver a prospectus meeting the
                  requirements of the Securities Act in connection with any
                  resale of Exchange Securities received in respect of such
                  Registrable Securities pursuant to the Exchange Offer";

                                       27

<PAGE>

         and (y) a statement to the effect that by a broker-dealer making the
         acknowledgment described in clause (x) and by delivering a Prospectus
         in connection with the exchange of Registrable Securities, the
         broker-dealer will not be deemed to admit that it is an underwriter
         within the meaning of the Securities Act; and

                  (B) in the case of any Exchange Offer Registration Statement,
         the Company and the Trust agree to deliver to the Initial Purchasers or
         to another representative of the Participating Broker-Dealers, if
         requested by any such Initial Purchasers or such other representative
         of the Participating Broker-Dealers, on behalf of the Participating
         Broker-Dealers upon consummation of the Exchange Offer (i) an opinion
         of counsel in form and substance reasonably satisfactory to the Initial
         Purchasers or such other representative of the Participating
         Broker-Dealers, covering the matters customarily covered in opinions
         requested in connection with Exchange Offer Registration Statements and
         such other matters as may be reasonably requested (it being agreed that
         the matters to be covered by such opinion may be subject to customary
         qualifications and exceptions), (ii) an officers' certificate
         containing certifications substantially similar to those set forth in
         Section 5(d) of the Purchase Agreement and such additional
         certifications as are customarily delivered in a public offering of
         debt securities and (iii) as well as upon the effectiveness of the
         Exchange Offer Registration Statement, a comfort letter, in each case,
         in customary form if permitted by Statement on Auditing Standards No.
         72.

                  The Company or the Trust may require each seller of
Registrable Securities as to which any registration is being effected to furnish
to the Company or the Trust, as applicable, such information regarding such
seller as may be required by the staff of the SEC to be included in a
Registration Statement. The Company or the Trust may exclude from such
registration the Registrable Securities of any seller who unreasonably fails to
furnish such information within a reasonable time after receiving such request.
The Company shall have no obligation to register

                                       28

<PAGE>

under the Securities Act the Registrable Securities of a seller who so fails to
furnish such information.

                  In the case of (1) a Shelf Registration Statement or (2)
Participating Broker-Dealers who have notified the Company and the Trust that
they will be utilizing the Prospectus contained in the Exchange Offer
Registration Statement as provided in Section 3(t) hereof, are seeking to sell
Exchange Securities and are required to deliver Prospectuses each Holder agrees
that, upon receipt of any notice from the Company or the Trust of the happening
of any event of the kind described in Section 3(e)(ii), 3(e)(iii), 3(e)(v) or
3(e)(vi) hereof, such Holder will forthwith discontinue disposition of
Registrable Securities pursuant to a Registration Statement until such Holder's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 3(i) hereof or until it is advised in writing (the "Advice") by the
Company and the Trust that the use of the applicable Prospectus may be resumed,
and, if so directed by the Company and the Trust, such Holder will deliver to
the Company or the Trust (at the Company's or the Trust's expense, as the case
requires) all copies in such Holder's possession, other than permanent file
copies then in such Holder's possession, of the Prospectus covering such
Registrable Securities or Exchange Securities, as the case may be, current at
the time of receipt of such notice. If the Company or the Trust shall give any
such notice to suspend the disposition of Registrable Securities or Exchange
Securities, as the case may be, pursuant to a Registration Statement, the
Company and the Trust shall use their best efforts to file and have declared
effective (if an amendment) as soon as practicable an amendment or supplement to
the Registration Statement and shall extend the period during which such
Registration Statement shall be maintained effective pursuant to this Agreement
by the number of days in the period from and including the date of the giving of
such notice to and including the date when the Company and the Trust shall have
made available to the Holders (x) copies of the supplemented or amended
Prospectus necessary to resume such dispositions or (y) the Advice.

                  4. Indemnification and Contribution. In connection with any
Registration Statement, the Company and the Trust shall,

                                       29

<PAGE>

jointly and severally, indemnify and hold harmless each Initial Purchaser, each
Holder, each underwriter who participates in an offering of the Registrable
Securities, each Participating Broker-Dealer, each Person, if any, who controls
any of such parties within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act and each of their respective directors, officers,
employees and agents, as follows:

                  (i) from and against any and all loss, liability, claim,
         damage and expense whatsoever, joint or several, as incurred, arising
         out of any untrue statement or alleged untrue statement of a material
         fact contained in any Registration Statement (or any amendment
         thereto), covering Registrable Securities or Exchange Securities,
         including all documents incorporated therein by reference, or the
         omission or alleged omission therefrom of a material fact required to
         be stated therein or necessary to make the statements therein not
         misleading or arising out of any untrue statement or alleged untrue
         statement of a material fact contained in any Prospectus (or any
         amendment or supplement thereto) or the omission or alleged omission
         therefrom of a material fact necessary in order to make the statements
         therein, in the light of the circumstances under which they were made,
         not misleading;

                  (ii) from and against any and all loss, liability, claim,
         damage and expense whatsoever, joint or several, as incurred, to the
         extent of the aggregate amount paid in settlement of any litigation, or
         any investigation or proceeding by any court or governmental agency or
         body, commenced or threatened, or of any claim whatsoever based upon
         any such untrue statement or omission, or any such alleged untrue
         statement or omission, if such settlement is effected with the prior
         written consent of the Company; and

                  (iii) from and against any and all expenses whatsoever, as
         incurred (including reasonable fees and disbursements of counsel chosen
         by such Holder, such Participating Broker-Dealer, or any underwriter
         (except to the extent otherwise expressly provided in Section 4(c)
         hereof)), reasonably incurred in investigating, preparing or defending

                                       30

<PAGE>

         against any litigation, or any investigation or proceeding by any court
         or governmental agency or body, commenced or threatened, or any claim
         whatsoever based upon any such untrue statement or omission, or any
         such alleged untrue statement or omission, to the extent that any such
         expense is not paid under subparagraph (i) or (ii) of this Section
         4(a);

provided, however, that (i) this indemnity does not apply to any loss,
liability, claim, damage or expense to the extent arising out of an untrue
statement or omission or alleged untrue statement or omission made in reliance
upon and in conformity with written information furnished in writing to the
Company or the Trust by such Holder, such Participating Broker-Dealer or any
underwriter with respect to such Holder, Participating Broker-Dealer or any
underwriter, as the case may be, expressly for use in the Registration Statement
(or any amendment thereto) or any Prospectus (or any amendment or supplement
thereto) and (ii) the Company and the Trust shall not be liable to any such
Holder, Participating Broker-Dealer, any underwriter or controlling person, with
respect to any untrue statement or alleged untrue statement or omission or
alleged omission in any preliminary Prospectus to the extent that any such loss,
liability, claim, damage or expense of any Holder, Participating Broker-Dealer,
any underwriter or controlling person results from the fact that such Holder,
any underwriter or Participating Broker-Dealer sold Securities to a person to
whom there was not sent or given, at or prior to the written confirmation of
such sale, a copy of the final Prospectus as then amended or supplemented if the
Company had previously furnished copies thereof to such Holder, underwriter or
Participating Broker-Dealer and the loss, liability, claim, damage or expense of
such Holder, underwriter, Participating Broker-Dealer or controlling person
results from an untrue statement or omission of a material fact contained in the
preliminary Prospectus which was corrected in the final Prospectus. Any amounts
advanced by the Company or the Trust to an indemnified party pursuant to this
Section 4 as a result of such losses shall be returned to the Company or the
Trust if it shall be finally determined by such a court in a judgment not
subject to appeal or final review that

                                       31

<PAGE>

such indemnified party was not entitled to indemnification by the Company or the
Trust.

                  (b) Each Holder agrees, severally and not jointly, to
indemnify and hold harmless the Company, the Trust, any underwriter and the
other selling Holders and each of their respective directors, officers
(including each officer of the Company and the Trust who signed the Registration
Statement), employees and agents and each Person, if any, who controls the
Company, the Trust, any underwriter or any other selling Holder within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act,
from and against any and all loss, liability, claim, damage and expense
whatsoever described in the indemnity contained in Section 4(a) hereof, as
incurred, but only with respect to untrue statements or omissions, or alleged
untrue statements or omissions, made in the Registration Statement (or any
amendment thereto) or any Prospectus (or any amendment or supplement thereto) in
reliance upon and in conformity with written information furnished to the
Company or the Trust by such selling Holder with respect to such Holder
expressly for use in the Registration Statement (or any amendment thereto), or
any such Prospectus (or any amendment or supplement thereto); provided, however,
that, in the case of Shelf Registration Statement, no such Holder shall be
liable for any claims hereunder in excess of the amount of net proceeds received
by such Holder from the sale of Registrable Securities pursuant to such Shelf
Registration Statement.

                  (c) Each indemnified party shall give prompt notice to each
indemnifying party of any action commenced against it in respect of which
indemnity may be sought hereunder, enclosing a copy of all papers properly
served on such indemnified party, but failure to so notify an indemnifying party
shall not relieve such indemnifying party from any liability which it may have
under this Section 4, except to the extent that it is materially prejudiced by
such failure. An indemnifying party may participate at its own expense in the
defense of such action. If an indemnifying party so elects within a reasonable
time after receipt of such notice, an indemnifying party, severally or jointly
with any other indemnifying parties receiving such notice, may assume the
defense of such action with counsel chosen

                                       32

<PAGE>

by it and reasonably acceptable to the indemnified parties defendant in such
action, provided, however, that if (i) representation of such indemnified party
by the same counsel would present a conflict of interest or (ii) the actual or
potential defendants in, or targets of, any such action include both the
indemnified party and the indemnifying party and any such indemnified party
reasonably determines that there may be legal defenses available to such
indemnified party which are different from or in addition to those available to
such indemnifying party, then in the case of clauses (i) and (ii) of this
Section 4(c) such indemnifying party and counsel for each indemnifying party or
parties shall not be entitled to assume such defense. If an indemnifying party
is not entitled to assume the defense of such action as a result of the proviso
to the preceding sentence, counsel for such indemnifying party and counsel for
each indemnified party or parties shall be entitled to conduct the defense of
such indemnified party or parties. If an indemnifying party assumes the defense
of such action, in accordance with and as permitted by the provisions of this
paragraph, such indemnifying parties shall not be liable for any fees and
expenses of counsel for the indemnified parties incurred thereafter in
connection with such action. In no event shall the indemnifying parties be
liable for the fees and expenses of more than one counsel (in addition to local
counsel), separate from its own counsel, for-all indemnified parties in
connection with any one action or separate but similar or related actions in the
same jurisdiction arising out of the same general allegations or circumstances.
No indemnifying party shall, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any litigation, or any investigation or proceeding by
any governmental agency or body, commenced or threatened, or any claim
whatsoever in respect of which indemnification or contribution could be sought
under this Section 4 (whether or not the indemnified parties are actual or
potential parties thereto), unless such settlement, compromise or consent (i)
includes an unconditional written release in form and substance satisfactory to
the indemnified parties of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not include
a statement as to

                                       33
<PAGE>

or an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party.

                  (d) Notwithstanding the last sentence of Section 4(c), if at
any time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for reasonable fees and expenses of counsel
pursuant to Section 4(a)(iii) above, such indemnifying party agrees that it
shall be liable for any settlement effected without its written consent if (i)
such settlement is entered into more than 45 days after receipt by such
indemnifying party of the aforesaid request, (ii) such indemnifying party shall
have received notice of the terms of such settlement at least 30 days prior to
such settlement being entered into and (iii) such indemnifying party shall not
have reimbursed such indemnified party in accordance with such request prior to
the date of such settlement; provided that an indemnifying party shall not be
liable for any such settlement effected without its consent if such indemnifying
party (1) reimburses such indemnified party in accordance with such request to
the extent it considers reasonable and (2) provides written notice to the
indemnified party substantiating the unpaid balance as unreasonable, in each
case prior to the date of such settlement.

                  (e) In order to provide for just and equitable contribution in
circumstances under which any of the indemnity provisions set forth in this
Section 4 is for any reason held to be unavailable to the indemnified parties
although applicable in accordance with its terms, the Company, the Trust, and
the Holders shall contribute to the aggregate losses, liabilities, claims,
damages and expenses of the nature contemplated by such indemnity agreement
incurred by the Company, the Trust, and the Holders, as incurred; provided that
no Person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the 1933 Act) shall be entitled to contribution from any Person that
was not guilty of such fraudulent misrepresentation. As between the Company, the
Trust, and the Holders, such parties shall contribute to such aggregate losses,
liabilities, claims, damages and expenses of the nature contemplated by such
indemnity agreement in such proportion as shall be appropriate to reflect the
relative fault of the Company and Trust, on the one hand, and

                                       34

<PAGE>

the Holders, on the other hand, with respect to the statements or omissions
which resulted in such loss, liability, claim, damage or expense, or action in
respect thereof, as well as any other relevant equitable considerations. The
relative fault of the Company and the Trust, on the one hand, and of the
Holders, 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 or the Trust, on the one hand, or by or on behalf of the
Holders, on the other, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company, the Trust and the Holders of the Registrable Securities agree that
it would not be just and equitable if contribution pursuant to this Section 4
were to be determined by pro rata allocation or by any other method of
allocation that does not take into account the relevant equitable
considerations. For purposes of this Section 4, each affiliate of a Holder, and
each director, officer, employee, agent and Person, if any, who controls a
Holder or such affiliate within the meaning of Section 15 of the Securities Act
or Section 20 of the Exchange Act shall have the same rights to contribution as
such Holder, and each director of each of the Company or the Trust, each officer
of each of the Company or the Trust who signed the Registration Statement, and
each Person, if any, who controls each of the Company and the Trust within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act
shall have the same rights to contribution as each of the Company or the Trust.

                  5.   Participation in Underwritten Registrations.  No
Holder may participate in any underwritten registration hereunder unless such
Holder (a) agrees to sell such Holder's Registrable Securities on the basis
provided in any underwriting arrangements approved by the Persons entitled
hereunder to approve such arrangements and (b) completes and executes all
reasonable questionnaires, powers of attorney, indemnities, underwriting
agreements, lock-up letters and other documents reasonably required under the
terms of such underwriting arrangements.

                                       35

<PAGE>


                  6. Selection of Underwriters. The Holders of Registrable
Securities covered by the Shelf Registration Statement who desire to do so may
sell the securities covered by such Shelf Registration in an underwritten
offering. In any such underwritten offering, the underwriter or underwriters and
manager or managers that will administer the offering will be selected by the
Holders of a majority in aggregate principal amount of the Registrable
Securities included in such offering; provided, however, that such underwriters
and managers must be reasonably satisfactory to the Company and the Trust.

                  7. Miscellaneous.

                  (a) Rule 144 and Rule 144A. For so long as the Company or the
Trust is subject to the reporting requirements of Section 13 or 15 of the
Exchange Act and any Registrable Securities remain outstanding, the Company and
the Trust, as the case may be, will their its best efforts to file the reports
required to be filed by it under the Securities Act and Section 13(a) or 15(d)
of the Exchange Act and the rules and regulations adopted by the SEC thereunder,
that if it ceases to be so required to file such reports, it will, upon the
request of any Holder of Registrable Securities (a) make publicly available such
information as is necessary to permit sales of their securities pursuant to Rule
144 under the Securities Act, (b) deliver such information to a prospective
purchaser as is necessary to permit sales of their securities pursuant to Rule
144A under the Securities Act and it will take such further action as any Holder
of Registrable Securities may reasonably request, and (c) take such further
action that is reasonable in the circumstances, in each case, to the extent
required from time to time to enable such Holder to sell its Registrable
Securities without registration under the Securities Act within the limitation
of the exemptions provided by (i) Rule 144 under the Securities Act, as such
rule may be amended from time to time, (ii) Rule 144A under the Securities Act,
as such rule may be amended from time to time, or (iii) any similar rules or
regulations hereafter adopted by the SEC. Upon the request of any Holder of
Registrable Securities, the Company and the Trusts will deliver to such Holder a
written statement as to whether it has complied with such requirements.

                                       36

<PAGE>

                  (b) No Inconsistent Agreements. The Company or the Trust has
not entered into nor will the Company or the Trust on or after the date of this
Agreement enter into any agreement which is inconsistent with the rights granted
to the Holders of Registrable Securities in this Agreement or otherwise
conflicts with the provisions hereof. The rights granted to the Holders
hereunder do not in any way conflict with and are not inconsistent with the
rights granted to the holders of the Company's or the Trust's other issued and
outstanding securities under any such agreements.

                  (c) Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, modified or
supplemented, and waivers or consents to departures from the provisions hereof
may not be given unless the Company and the Trust has obtained the written
consent of Holders of at least a majority in aggregate principal amount of the
outstanding Registrable Securities affected by such amendment, modification,
supplement, waiver or departure; provided no amendment, modification or
supplement or waiver or consent to the departure with respect to the provisions
of Section 4 hereof shall be effective as against any Holder of Registrable
Securities unless consented to in writing by such Holder of Registrable
Securities. Notwithstanding the foregoing sentence, (i) this Agreement may be
amended, without the consent of any Holder of Registrable Securities, by written
agreement signed by the Company, the Trust and DLJ, to cure any ambiguity,
correct or supplement any provision of this Agreement that may be inconsistent
with any other provision of this Agreement or to make any other provisions with
respect to matters or questions arising under this Agreement which shall not be
inconsistent with other provisions of this Agreement, (ii) this Agreement may be
amended, modified or supplemented, and waivers and consents to departures from
the provisions hereof may be given, by written agreement signed by the Company,
the Trust and DLJ to the extent that any such amendment, modification,
supplement, waiver or consent is, in their reasonable judgment, necessary or
appropriate to comply with applicable law (including any interpretation of the
Staff of the SEC) or any change therein and (iii) to the extent any provision of
this Agreement relates to the Initial Purchasers, such provision may be amended,
modified

                                       37

<PAGE>

or supplemented, and waivers or consents to departures from such provisions may
be given, by written agreement signed by DLJ, the Company and the Trust.

                  (d) Notices. All notices and other communications provided for
or permitted hereunder shall be made in writing by hand-delivery, registered
first-class mail, telex, telecopier, or any courier guaranteeing overnight
delivery (i) if to a Holder, at the most current address given by such Holder to
the Company or the Trust by means of a notice given in accordance with the
provisions of this Section 7(d), which address initially is, with respect to the
Initial Purchasers, the address set forth in the Purchase Agreement; and (ii) if
to the Company or the Trust, initially at the Company's address set forth in the
Purchase Agreement and thereafter at such other address, notice of which is
given in accordance with the provisions of this Section 7(d).

                  All such notices and communications shall be deemed to have
been duly given: at the time delivered by hand, if personally delivered; five
Business Days after being deposited in the mail, postage prepaid, if mailed;
when answered back, if telexed; when receipt is acknowledged, if telecopied; and
on the next Business Day, if timely delivered to an air courier guaranteeing
overnight delivery.

                  Copies of all such notices, demands, or other communications
shall be concurrently delivered by the Person giving the same to the Trustee, at
the address specified in the Indenture.

                  (e) Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors, assigns and transferees of the
Initial Purchasers, including, without limitation and without the need for an
express assignment, subsequent Holders; provided, however, that nothing herein
shall be deemed to permit any assignment, transfer or other disposition of
Registrable Securities in violation of the terms of the Purchase Agreement or
the Indenture. If any transferee of any Holder shall acquire Registrable
Securities, in

                                       38

<PAGE>


any manner, whether by operation of law or otherwise, such Registrable
Securities shall be held subject to all of the terms of this Agreement, and by
taking and holding such Registrable Securities, such Person shall be
conclusively deemed to have agreed to be bound by and to perform all of the
terms and provisions of this Agreement and such Person shall be entitled to
receive the benefits hereof.

                  (f) Third Party Beneficiary. Each of the Initial Purchasers
shall be a third party beneficiary of the agreements made hereunder between the
Company and the Trust, on the one hand, and the Holders, on the other hand, and
shall have the right to enforce such agreements directly to the extent it deems
such enforcement necessary or advisable to protect its rights or the rights of
Holders hereunder.

                  (g) Counterparts. This Agreement may be executed in any number
of counterparts and by the parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement.

                  (h) Headings.  The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

                  (i) GOVERNING LAW. THIS AGREEMENT SHALL BE DEEMED TO HAVE BEEN
MADE IN THE STATE OF NEW YORK. THE VALIDITY AND INTERPRETATION OF THIS
AGREEMENT, AND THE TERMS AND CONDITIONS SET FORTH HEREIN, SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT
GIVING EFFECT TO ANY PROVISIONS RELATING TO CONFLICTS OF LAWS. EACH OF THE
PARTIES HERETO AGREES TO SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE
OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS
AGREEMENT.

                  (j) Severability. In the event that any one or more of the
provisions contained herein, or the application thereof in any circumstance, is
held invalid, illegal or unenforceable, the validity, legality and
enforceability of any such provision in every other respect and of the remaining
provisions contained herein shall not be affected or impaired thereby.

                  (k) Securities Held by the Company, the Trust or its
Affiliates. Whenever the consent or approval of Holders of a specified
percentage of Registrable Securities is required hereunder, Registrable
Securities held by the Company, the Trust or its affiliates (as such term is
defined in Rule 405 under the Securities Act) shall not be counted in
determining whether such consent or approval was given by the Holders of such
required percentage.
