entered into as of May 30, 1995 by and between Lincoln Insurance Group, Inc., a
Delaware corporation ("Seller") and Markel Corporation, a Virginia corporation
("Buyer").

dated as of April 5, 1995 (the "Stock Purchase Agreement") pursuant to which
Seller will sell to Buyer all of the issued and outstanding shares of common
stock of Lincoln Insurance Company, a Delaware domestic insurance corporation

                 In connection with the Stock Purchase Agreement, Seller has
agreed to indemnify and hold harmless Buyer with respect to the adequacy of
certain of the loss reserves and reserves for uncollectible reinsurance
maintained by the Company.  This Agreement is intended to provide Buyer,
subject to the Deductible and other limitations set forth herein, with
collateral security for adverse development in certain of the Company's loss
reserves and reserves for uncollectible reinsurance.  This Agreement is also
intended to provide, again subject to the Deductible and the other limitations
set forth herein, a mechanism for reimbursing Buyer as and when cash losses are
suffered with respect to such adverse development.

                 NOW, THEREFORE, in consideration of the foregoing recitals and
the mutual covenants contained herein and in the Stock Purchase Agreement, the
parties agree as follows:

perform an additional determination of the Final Settlement Amount within sixty
(60) days after the delivery of its notice concerning such disagreement.
Seller's Auditors shall deliver to Buyer and Buyer's Auditors within such sixty

Auditors shall each provide to the other access to its work papers related to
its calculation of the Final Settlement Amount.  If Seller's Auditors and
Buyer's Auditors cannot agree on a single determination of the Final Settlement
Amount within twenty (20) days after delivery to Buyer of the determination of
Seller's Auditors, then Seller's Auditors and Buyer's Auditors shall, within
ten (10) days thereafter, mutually select an independent third auditor whose
determination of the Final Settlement Amount, which shall be not more than the
determination by Buyer's Auditors nor less than the determination by Seller's
Auditors and shall be made within sixty (60) days after such auditor's
selection and shall be delivered to Buyer and Seller, shall be final and
binding.

                                  (c) The determination of the Final Settlement
Amount shall be deemed to be final upon the earliest to occur of (i) Buyer's

within forty-five (45) days after Seller's receipt thereof, (iii) Seller's
failure to deliver Seller's Auditors' determination to Buyer within sixty (60)
days after delivery to Buyer of the notice referred to in clause (ii) of this
Section 2.3(c), (iv) the receipt by Buyer and Seller of the written agreement
by Seller's Auditors and Buyer's Auditors on a single determination, and (v)
the receipt by Buyer and Seller of the determination made by the independent
auditor selected by Buyer's Auditors and Seller's Auditors.  If any objection
or dispute exists at any time with respect only to a portion of the Final
Settlement Amount, the portion of the Final Settlement Amount not objected to
or disputed shall be deemed to be final upon receipt of notice by Buyer from
Seller, or by Seller from Buyer, that such portion is not objected to or in
dispute.

                          2.4     FUNDING AND REFUNDING OF INDEMNITY.  (a)
Seller agrees to provide for establishment and maintenance of security for the

Trustee under the Trust Agreement funds and/or securities which satisfy the
relevant provisions thereof, or (ii) deliver to the Buyer, for the benefit of
the Buyer and the Company, one or more Letters of Credit, or (iii) make any
combination of deliveries satisfying clauses (i) and (ii), in any such case
having an aggregate value or principal amount, as the case may be, sufficient
to cause the aggregate value of the total assets held under the Trust
Agreement, plus the aggregate undrawn principal amount of the Letters of Credit
held by Buyer, to equal the Adjustment Amount; provided, that if the Adjustment
Amount is less than (x) the aggregate value of the assets held under the Trust
Agreement determined as of the relevant Determination Date plus (y) the
aggregate undrawn principal amount of the Letters of Credit delivered to Buyer
pursuant to this Section 2.4, Buyer shall return to Seller Letters of Credit,
or the Trustee shall deliver to Seller funds and/or securities, and/or any
combination of the foregoing, so that the aggregate value of the assets held
under the Trust Agreement and/or the aggregate undrawn principal amount of the
Letters of Credit held by Buyer is equal to the Adjustment Amount.

                                  (b) From and after the time that the amount
of Net Loss Payments less Current Recoverables on Paid Losses less Indemnity
Payments exceeds, in the aggregate for both Insurance Books, thirty million six
hundred thousand five hundred eighty-four Dollars ($30,600,584), Buyer shall be
entitled to draw upon the Letters of Credit and/or withdraw assets from the
Trust up to an aggregate amount equal to the lesser of (i) such excess, and
(ii) the Maximum Adjustment Amount as of the date of draw or withdrawal, as the
case may be.

                                  (c) Buyer shall deliver to Seller the
following: (i) simultaneously with delivery to a bank that has issued a Letter
of Credit, a copy of each sight draft and (ii) simultaneously with delivery to
the Trustee under the Trust Agreement, a copy of each withdrawal

   11
notice, in each case accompanied by a certificate of an officer of Buyer
stating that such amounts have been drawn or withdrawn, as the case may be,
pursuant to and in accordance with this Agreement.

                                  (d) If Seller believes that amounts drawn
under the Letters of Credit or assets withdrawn from the Trust pursuant to this
Section 2.4 are in excess of the amount to be drawn or withdrawn hereunder, the
resolution thereof shall be part of the determination of the Final Settlement
Amount pursuant to Section 2.3.

                                  (e) If at any time prior to the final
determination of the Final Settlement Amount, Buyer receives notification of
termination of the Trust Agreement and the aggregate undrawn principal amount
of the Letters of Credit is less than the Adjustment Amount, determined as of
the most recent Determination Date, Buyer shall be entitled to withdraw assets
from the Trust in the amount of such insufficiency and deposit such amounts in
a separate account in the name of Buyer or the Company in any bank meeting the
qualifications for serving as Trustee under the Trust Agreement, apart from its
general assets, in trust as security for and to provide funding of Seller's
indemnity obligations hereunder under the same terms and conditions as if such
assets had remained in the Trust.

                                  (f) If the Adjustment Amount (other than the
Final Settlement Amount) is less than zero, within five (5) Business Days after
determination of such Adjustment Amount, Buyer shall pay to Seller by wire
transfer an amount equal to the lesser of (i) the amount by which such
Adjustment Amount is less than zero or (ii) the aggregate of all Indemnity
Payments previously paid to or received by Buyer.

                          2.5     FUNDING OF INDEMNITY AND DISPOSITION OF
COLLATERAL UPON FINAL SETTLEMENT.  (a) If the Final Settlement Amount is
greater than zero, within five (5) Business Days after final determination of
the Final Settlement Amount, Seller shall pay to Buyer an amount equal





                                       11
   12
to the Final Settlement Amount.  Such amount shall be paid by Seller, in its
discretion, by wire transfer, through liquidation of assets held in the Trust,
or by requiring Buyer to draw against the Letters of Credit held by Buyer.
Upon receipt of the Final Settlement Amount all assets remaining in the Trust
and all remaining Letters of Credit held by Buyer shall be delivered to Seller,
and the Trust Agreement shall terminate.

                                  (b) If the Final Settlement Amount is less
than zero, within five (5) Business Days after final determination of the Final
Settlement Amount, Buyer shall pay to Seller by wire transfer an amount equal
to the lesser of (i) the amount by which the Final Settlement Amount is less
than zero or (ii) the aggregate of all Indemnity Payments previously paid to or
received by Buyer.

                          2.6     PAYMENT TERMS.  Payments due pursuant to the
terms of this Agreement shall be made by wire transfer in immediately available
funds within five (5) Business Days following the date that the payment amount
becomes final.  The party to receive payment shall provide the payor with
appropriate wire transfer information.  Any payments not paid within such five
(5) Business Day period shall bear interest at a per annum rate equal to two
percent (2%) in excess of the prime lending rate announced from time to time by
Chase Manhattan Bank, N.A.

                          2.7     REDUNDANCIES; NEGATIVE ADJUSTMENT AMOUNT.  A
redundancy in the Reserves for Losses and Loss Adjustment Expenses in one
Insurance Book shall be applied to offset deficiencies in the Reserves for
Losses and Loss Adjustment Expenses in the other Insurance Book, but in no
event shall a redundancy (or a negative Adjustment Amount or Final Settlement
Amount resulting from a redundancy) create any obligation on the part of Buyer
to make any payment to Seller, except for the purpose of repaying to Seller all
or part of the Indemnity Payments previously paid to Buyer to which it is later
determined Buyer was not entitled.

                          2.8     MAXIMUM INDEMNITY.  Seller shall not be
obligated to pay any amounts for indemnification under Article 9 of the Stock
Purchase Agreement, or fund or pay any amounts under this Agreement in excess
in the aggregate under both Agreements of an amount equal to the Purchase
Price.

                          2.9     PURCHASE PRICE ADJUSTMENT.  All payments made
by Seller pursuant to this Agreement shall be deemed to be adjustments of the
Purchase Price under the Stock Purchase Agreement.

                 3.       REPORTS; INSPECTION; PROCEDURES.

                          3.1     ANNUAL STATEMENTS, QUARTERLY STATEMENTS AND
INVESTIGATION.  Buyer shall deliver to Seller by March 15 in each of the years
1996-2004 (inclusive) a copy of the Annual Statement.  In addition, from and
after such time as Buyer shall be entitled to deliver Indemnification
Statements on a quarterly basis through the Final Settlement Date, within sixty
(60) days after the end of each fiscal quarter of the Company, Buyer shall
deliver to Seller a copy of the Quarterly Statement filed by the Company or its
successors with the applicable Department of Insurance for the relevant fiscal
quarter.  Buyer shall permit Seller (through its employees or representatives)
at all reasonable times during normal business hours to investigate any of the
Company's documents or records, including without limitation, to audit the
payments made by the Company for losses and loss adjustment expenses related to
the Insurance Books, that may, in the reasonable opinion of Seller, be relevant
to the determination of payment obligations pursuant to the terms of this
Agreement.

                          3.2     CONFIDENTIALITY AND CONFLICT.  Seller agrees
that it, and its employees and representatives, will hold in confidence and not
disclose to any third party any of the information provided by Buyer to Seller
pursuant to this Agreement.  Before Buyer shall be required to provide
information to, or permit investigation by, Seller or its employees or





                                       13
   14
representatives, Buyer shall be provided certification in form and substance
reasonably satisfactory to it that such representative does not have any
interest, including, without limitation, serving as counsel to insureds on
policies of insurance written by the Company or as counsel to reinsurers of
insurance policies in an Insurance Book, that is or could be in conflict with
the interests of the Company or Buyer.

                          3.3     LOSS SETTLEMENT PROCEDURES.  Buyer agrees
that, for the period from the Closing Date until the Final Settlement Date,
each of Buyer and the Company will, in relation to claims subject to indemnity
hereunder:

                                  3.3.1       Not settle claims except in the
         ordinary course of business and in accordance with current practices
         of other insurance subsidiaries of Buyer or otherwise in accordance
         with practices no less stringent than standard insurance industry
         practices;

                                  3.3.2       Use commercially reasonable
         efforts to obtain reimbursement of claims from reinsurers; and

                                  3.3.3       Permit Seller (through its
         employees or representatives) at all reasonable times during normal
         business hours to make such investigation of, or audit, any claims,
         actual or prospective (or any other matter which may in the reasonable
         opinion of Seller be relevant to the Adjustment Amount) and furnish
         Seller with copies of such documents as Seller may reasonably request,
         it being understood that Seller's right to investigate and audit the
         claims settlement procedure shall be no less in scope than rights
         afforded to the Company's reinsurers.

                 4.       EXTRAORDINARY LOSSES.  (a) Reserves for Losses and
Loss Adjustment Expenses in respect of an Insurance Book shall include a
provision with respect to specific claims or series of similar claims for all
losses, liabilities and expenses incurred by the Company in





                                       14
   15
connection with any action, suit or proceeding arising out of or relating to
the actual or alleged bad faith, fraud, error or omission by the Company in
connection with the handling of such claims under insurance policies in such
Insurance Book either (i) on or before the date hereof or (ii) if Seller has
consented to the manner in which the relevant claim or series of similar claims
is being handled, after the date hereof, and (b) Reserves for Uncollectible
Reinsurance in respect of the Pre-1984 Book shall include a provision with
respect to specific claims or series of similar claims for all losses,
liabilities and expenses (including, without limitation, expenses for
declaratory judgment actions) incurred by the Company in respect of either
Insurance Book in connection with any action, suit or proceeding arising out of
or relating to the actual or alleged error or omission by the Company in
connection with the handling prior to April 1, 1995 of such claims with
reinsurers.

                 5.       COMMUTATION OF UNCOLLECTIBLE REINSURANCE.  Buyer
shall be entitled to settle and commute any reinsurance recoverable; and any
losses, including, without limitation, expenses of collection, settlement or
commutation, resulting therefrom, shall be reflected in the Adjustment Amount
if Seller consents to such settlement or commutation, which consent shall not
be unreasonably withheld or delayed.

                 6.       ASSIGNMENT OF UNCOLLECTIBLE REINSURANCE.  Buyer shall
cause the Company to assign to Seller any reinsurance recoverable that would be
reflected in the Adjustment Amount promptly after such reinsurance recoverable
is written off or reserved against in its entirety by the Company; provided
that Seller shall use commercially reasonable efforts to avoid damage to the
relationship between the Company and the person owing such recoverable.

                 7.       SUPERFUND TAXATION.  If at any time on or prior to
the termination of this Agreement any Tax is assessed against the Company in
connection with the Comprehensive Environmental, Response, Compensation and
Liability Act, 42 U.S.C. Section 9601, et. seq., or any amendment thereto,
which results directly in a limitation of the Company's liability with respect
to





                                       15
   16
the Pre-1984 Book, the direct result of which is a reduction in the Reserves
for Losses and Loss Adjustment Expenses with respect to the Pre-1984 Book (the
"Superfund Reduction"), the parties agree that such Tax assessment, up to the
amount of the Superfund Reduction, will be taken into account in calculating
the Adjustment Amount, and Buyer will not have a claim for indemnification with
respect to such amount under the Stock Purchase Agreement; provided, that Buyer
shall be entitled to seek indemnification under the Stock Purchase Agreement
for the amount of any such Tax assessment in excess of the Superfund Reduction.

                 8.       CONSENT NOT TO BE UNREASONABLY WITHHELD.  Whenever
pursuant to this Agreement an action of one party is subject to the consent of
the other party that is not to be unreasonably withheld or delayed, the party
whose consent is required shall respond within a reasonable period of time,
based upon the facts and circumstances relating to the subject matter of the
action requiring consent, and shall, if it does not provide its consent, set
forth in writing and in reasonable detail the basis and reasons for denying
consent.  The party whose consent is required shall not be entitled to refuse
to respond to the request for consent or to respond that it is neither
consenting or denying consent.

                 9.       TERM AND GOVERNING LAW.  This Agreement shall become
effective concurrently with Closing under the Stock Purchase Agreement and
shall remain in full force and effect until the obligations of the parties
hereunder shall have been finally discharged in connection with settlement of
the Final Settlement Amount.  This Agreement shall be governed by, and
construed and enforced in accordance with, the laws of the State of Delaware.

                 10.      ASSIGNMENT.  In the event Buyer sells the Company to,
or merges the Company with, any subsidiary of Buyer, an insurance company rated
"A-" or better by A. M. Best Company or to such other entity as shall be
approved by Seller, which approval shall not be unreasonably withheld or
delayed, such entity to whom Buyer sells the Company, or with which





                                       16
   17
the Company merges, shall have all of the rights of Buyer under this Agreement;
provided, that any such assignment shall not increase Seller's liability
hereunder.  Except as provided in the immediately preceding sentence, neither
party may assign its rights or obligations under this Agreement without the
prior written consent of the other party.

                 11.      INCORPORATION BY REFERENCE.  The provisions of
Sections 11.2, 11.3, 11.4, 11.5, 11.6, 11.9, 11.10, 11.12, 11.13 and 11.14 of
the Stock Purchase Agreement are hereby incorporated by reference herein and

Agreement as of the day and year first above written.
