         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.

         SEE "RISK FACTORS"  COMMENCING ON PAGE ___ FOR CERTAIN INFORMATION THAT
SHOULD BE  CONSIDERED  BY HOLDERS  IN  DECIDING  WHETHER  TO TENDER OLD  CAPITAL
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.





         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."






         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




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.

                                       Letters of Transmittal  and  certificates
                                       representing  Old Capital  Securities

                                       sent to the Exchange Agent.




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
                                       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  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
                                       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

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

                                       The Letter of  Transmittal  states that,

                                       a prospectus,  a  broker-dealer  will not

                                       "underwriter"  within the meaning of the
                                       Securities  Act. Based on the position

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

Ratings..............................  The New Capital Securities are expected
                                       to be rated "BBB-" by Standard & Poor's
                                       Ratings Service and by Duff & Phelps
                                       Credit Rating Co., and "baa3" by Moody's
                                       Investors Service, Inc.



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
                                       any securities  exchange or for quotation

                                  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."





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".



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



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:





                                                                                                   Nine Months

Ratio of Earnings to Fixed Charges.............................  2.3    6.3     5.2    4.3   6.5        6.2

Gains from Sales of Investments and Gains from Sales of
Brokerage Programs.............................................  1.6    2.2     3.1    3.8   5.2        5.7


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
September  30,  1996,   which  are   incorporated   herein  by  reference.   See

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

                             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 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

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.



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.



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.



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:



(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.

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."



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."




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




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





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





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





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.





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.



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.





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



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.





Optional Prepayment

The Junior Subordinated  Debentures will be prepayable,  in whole or in part, at
the option of the  Company on or after  January 1, 2007 (the  "Initial  Optional
Prepayment Date"), at a prepayment price (the "Optional Prepayment Price") equal
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
the years indicated below:

Year                                                      Percentage

2007..................................................       104.355%
2008..................................................       103.920%

2015..................................................       100.871%
2016..................................................       100.436%
2017 and thereafter...................................       100.000%


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





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





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





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,





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.





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





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





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.





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






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.

                             CERTAIN LEGAL MATTERS

The validity of the New Junior Subordinated Debentures and the New Guarantee and
certain legal matters  relating  thereto will be passed upon by McGuire,  Woods,

threatened  with or made a party to any action,  suit or proceeding by reason of
the fact that he or she is, or was, a  director,  officer,  employee or agent of
such corporation.  Indemnification is also authorized with respect to a criminal
action or proceeding  where the person had no  reasonable  cause to believe that
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.

Article VII of the  Company's  Amended and  Restated  Articles of  Incorporation

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.
