                                       OF
                             MARKEL CAPITAL TRUST I

         THIS  DECLARATION OF TRUST is made as of December 30, 1996 (this "Trust
Agreement"),  by and between  Markel  Corporation,  a Virginia  corporation,  as
sponsor (the "Sponsor"),  and Chase Manhattan Bank Delaware,  a Delaware banking
corporation,  as trustee  (the  "Trustee").  The Sponsor and the Trustee  hereby
agree as follows:

         1. The trust created hereby shall be known as "Markel  Capital Trust I"
(the "Trust"),  in which name the Trustee or the Sponsor, to the extent provided
herein, may conduct the business of the Trust, make and execute  contracts,  and
sue and be sued.

         2. The Sponsor hereby assigns, transfers,  conveys and sets over to the
Trust the sum of ten dollars  ($10).  Such amount shall  constitute  the initial
trust estate.  It is the intention of the parties  hereto that the Trust created
hereby  constitute a business trust under Chapter 38 of Title 12 of the Delaware
Code,  12 Del. C. ss. 3801, et seq. (the  "Business  Trust Act"),  and that this
document constitute the governing instrument of the Trust. The Trustee is hereby
authorized  and  directed  to execute and file a  certificate  of trust with the
Delaware  Secretary of State in accordance  with the  provisions of the Business
Trust Act.

         3. The Sponsor and the Trustee  will enter into an amended and restated
Trust  Agreement or Declaration  satisfactory  to each such party to provide for
the  contemplated  operation of the Trust created hereby and the issuance of the
Capital  Securities (the "Capital  Securities")  and the Common  Securities (the
"Common  Securities")  referred to in the Offering  Memorandum  (as  hereinafter
defined). Prior to the execution and delivery of such amended and restated Trust
Agreement  or  Declaration,  the Trustee  shall not have any duty or  obligation
hereunder or with respect of the trust estate,  except as otherwise  required by
applicable  law or as may be  necessary to obtain  prior to such  execution  and
delivery any  licenses,  consents or  approvals  required by  applicable  law or
otherwise.  Notwithstanding  the  foregoing,  the  Trustee  may take all actions
deemed proper as are necessary to effect the transactions contemplated herein.

         4. The Sponsor,  as sponsor of the Trust, is hereby authorized,  in its
discretion,  (i) to prepare and  distribute  one or more  offering  memoranda in
preliminary  and final form,  including any  necessary or desirable  amendments,
relating  to the  offering  and sale of  Capital  Securities  of the  Trust in a
transaction  exempt from the registration  requirements of the Securities Act of
1933,  as amended  (the "1933  Act"),  and such other forms or filings as may be
required by the 1933 Act, the  Securities  Exchange Act of 1934, as amended,  or
the Trust  Indenture  Act of 1939,  as  amended,  in each case  relating  to the
Capital  Securities of the Trust (the "Offering  Memorandum");  (ii) to file and
execute  on behalf of the  Trust,  such  applications,  reports,  surety  bonds,
irrevocable consents,  appointments of attorney for service of process and other
papers and  documents  that shall be  necessary  or  desirable  to  register  or
establish the exemption from registration of the Capital Securities of the Trust
under the securities or "Blue Sky" laws of such jurisdictions as the Sponsor, on
behalf of the Trust, may deem necessary or desirable; (iii) to


                                      -1-




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

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

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

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

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

                                      -2-




         IN WITNESS WHEREOF,  the parties hereto have caused this Declaration of
Trust to be duly executed as of the day and year first above written.
