                            TRUST PURCHASE AGREEMENT

         THIS AGREEMENT, made and entered into this 16th day of July, 1998, is
by and among IAT REINSURANCE SYNDICATE LTD. ("Buyer"), a Bermuda corporation
with its principal office in Bermuda, and WILMINGTON TRUST COMPANY ("Trustee"),
a Delaware corporation with its principal office in Wilmington, Delaware, in its
capacity as Trustee of the McMillen Trust.

                              BACKGROUND STATEMENT

         The McMillen Trust (the "Trust") owns 3,087,500 shares of the issued
and outstanding common stock of McM Corporation ("McM"), a North Carolina
corporation headquartered in Raleigh, North Carolina. Buyer wishes to acquire
approximately 49% of the issued and outstanding shares of McM by buying
approximately 14% of such shares from the Trust and by buying approximately 35%
of such shares in a tender offer (the "Tender Offer") to all persons owning
shares other than the Trust. In consideration of the Trust's entering into this
Agreement and for not participating in the Tender Offer, the Buyer will deposit
with the Trust the sum of $8,864,390.00 (the "Fund"), to be held and invested
and reinvested by the Trust as provided in this Agreement.

                             STATEMENT OF AGREEMENT

         NOW, THEREFORE, in consideration of the foregoing, and the
representations, warranties, covenants and agreements contained herein, and
intending to be legally bound, the parties hereto agree as follows:

         1.       Sale and Purchase of Shares.

         (a)      Subject to the terms and conditions of this Agreement, the
Trustee shall sell, transfer, convey, assign and deliver to Buyer, and Buyer
shall purchase from the Trustee, 658,900 shares of McM (the "Purchased Shares").
At the Closing (as hereinafter defined), the Trust shall deliver to Buyer the
certificates representing the Purchased Shares, accompanied by stock powers duly
executed and such other documents of transfer as may be required to transfer
legal title to the Purchased Shares to Buyer.

         (b)      The purchase price for the Purchased Shares shall be $3.65 per
share or a total purchase price of $2,404,985.00 (the "Purchase Price"). The
Purchase Price shall be paid by Buyer to the Trustee at the Closing.

         (c)      The Closing of the purchase and sale of the Purchased Shares
(the "Closing") will take place at the offices of Ragsdale, Liggett & Foley,
Raleigh, North Carolina, within five business days after all of the conditions
precedent to closing have been satisfied or waived, or at such other place, time
and date as the parties may agree upon in writing (the "Closing Date").

         2.       Deposit of the Fund.

         (a)      Buyer agrees to transfer to the Trust the sum of $8,864,390.00
(the "Fund") on the Closing Date. The Fund shall be held by the Trust and
invested and reinvested by the Trustee in accordance with the instrument
creating the Trust as modified by orders of the Court of Chancery of the State
of Delaware. Any income earned on the Fund and any increases in the principal of
the Fund shall be and remain the sole property of the Trust. Buyer shall not be
responsible or liable for any decreases in the value of the Fund as a result of
investments by the Trustee.

         (b)      After the purchase and sale of the Purchased Shares, the Trust
will own 2,428,600 shares of McM (the "Retained Shares"). If Buyer makes an
offer at any time to purchase the Retained Shares, the parties agree that the
original principal amount of the Fund, or $8,864,390.00, regardless of any
increases or decreases in the value of the Fund or any income earned on the
Fund, shall constitute a credit against the purchase price for the Retained
Shares. Buyer by this Agreement is making no commitment to purchase or make an
offer to purchase the Retained Shares, and the Trust by this Agreement is making
no commitment to sell the Retained Shares. Nor are the parties agreeing to a
purchase price for the Retained Shares if and when an offer to sell or purchase
the Retained Shares shall occur.

         (c)      If the Trust at any time sells any of the Retained Shares to
any third party other than Buyer or Buyer's assignee, the Trust shall within
five (5) business days after such sale refund to Buyer an amount equal to $3.65
per share for each share of the Retained Shares sold to such third party.

         (d)      If McM at any time makes a filing for protection or
liquidation under any section of the United States Bankruptcy Code or similar
state law relating to insolvency or receivership, or if the insurance
commissioner of any state institutes receivership or liquidation proceedings
against McM, the Fund shall become the absolute property of the Trust subject to
no restrictions or obligations, and the Trust within five (5) business days of
any such filing or proceeding shall transfer to Buyer all of the Retained Shares
with no further consideration to be paid by Buyer to the Trust for such shares.
The Trust shall deliver to Buyer the certificates representing the Retained
Shares accompanied by stock powers duly executed and such other documents of
transfer as may be required to transfer legal title to the Retained Shares to
Buyer.

         3.       Representations and Warranties by the Trustee. The Trustee
hereby represents and warrants to Buyer as follows:

         (a)      The Trustee is a corporation duly incorporated, validly

         (d)      Neither the execution and delivery of, nor the performance of
its obligations under, this Agreement by the Trustee, nor the consummation of

or regulation of any court or governmental authority having jurisdiction over
the Trustee or any of the property of the Trust.

         (e)      The Trustee has not retained any broker or finder in
connection with the transactions contemplated herein so as to give rise to any
valid claim against Buyer for any fee, sales commissions, finders' fees,
financial advisory fee or other fees or expenses for which Buyer shall be
liable.

         4.       Representations and Warranties of Buyer. Buyer hereby
represents and warrants to the Trustee as follows:

         (a)      Buyer is a corporation duly incorporated, validly existing and
in good standing under the laws of Bermuda, and has full corporate power and
authority to carry on its business as now conducted.

         (b)      The execution, delivery and performance by Buyer of this
Agreement and the transactions contemplated hereby have been duly and validly

has the power, authority and capacity to enter into and perform its obligations

This Agreement has been duly and validly executed by Buyer and is the legal,
valid and binding obligation of Buyer, enforceable in accordance with its terms,
except as enforceability may be limited by equitable principles or by

         (c)      Neither the execution and delivery of, nor the performance of
its obligations under, this Agreement by Buyer, nor the consummation of the
transactions contemplated herein, will conflict with, violate or result in a
breach of any of the terms or provisions of, or constitute a default (with the

trust, lease,



                                       3

note, or other agreement or instrument to which Buyer is a party, conflict with
any provision of the charter documents of Buyer, or violate any law, order,
judgment, decree, rule or regulation of any court or governmental authority
having jurisdiction over Buyer or its property.

         (d)      The Purchased Shares acquired by Buyer pursuant to this
Agreement are being acquired for investment purposes only and not with a view to
any public distribution thereof, and Buyer will not offer to sell or otherwise
dispose of the shares so acquired by it in violation of any federal or state law
applicable to the sale, resale, or distribution of securities.

         (e)      Buyer has not retained any broker or finder in connection with
the transactions contemplated herein so as to give rise to any valid claim
against the Trustee or the Trust for any fee, sales commissions, finders' fees,
financial advisory fee or other fees or expenses for which the Trustee or the
Trust shall be liable.

         5.       Certain Covenants.

         (a)      The Trustee acknowledges that Buyer has already invested
$5,000,000 in capital for McM at a below market interest rate of 5% per annum
and plans to commit additional capital to McM in the future. The Trustee also
acknowledges that the management of Buyer has expertise in the management and
operation of insurance companies and that the devotion of time and expertise by
the management of Buyer to McM will cause Buyer to forego significant
opportunities in regard to other investments. Buyer intends to make available to
McM the services of Peter R. Kellogg, its president and chief executive officer,
in the management and direction of McM. Mr. Kellogg has vast experience and
background and a proven record of success in the management and operation of
insurance companies. Mr. Kellogg will devote significant time and effort to the
management of McM with no employment agreement and no compensation of any kind.
Nor will Buyer or Mr. Kellogg charge McM any management or advisory fees. Buyer
intends to negotiate an agreement with McM that will give Buyer rights to
purchase from McM for a nominal sum 60,000 shares of a new issue of preferred
stock of McM that will have a par value of $1000 per share, will not have a
vote, will not pay a dividend, will not be convertible into common stock of McM,
and will have such other rights, preferences and characteristics to which Buyer
and McM may agree, including but not limited to the right to a preference in any
liquidation or dissolution of McM equal to the par value of such preferred stock
before any amount is payable or distributable with respect to the common stock
of McM. The rights to purchase preferred stock of McM shall be exercisable only
if, at any time, Buyer's designees cease to control the board of directors of
McM or if the Trust sells to any third party other than Buyer or Buyer's
assignee any of the Retained Shares. The Trustee acknowledges that the issuance
of such rights to purchase preferred stock by McM to Buyer is appropriate in
order to properly compensate Buyer for its capital and management commitments to
McM. The Trustee covenants and agrees with Buyer that it will not oppose and
will support the issuance of the rights to purchase preferred stock of McM, and,
if required by law or requested by Buyer, the Trustee will vote all of the
Retained Shares in favor of the issuance of such rights.

         (b)      The Trustee covenants and agrees that it will not tender any
of the Retained Shares in the Tender Offer.



                                       4
   5

         (c)      Should Buyer subsequently wish to sell the Purchased Shares to
a third party on or before but not after December 31, 2003, Buyer shall first
obtain the written consent of the Trustee, such consent not to be unreasonably
withheld if the Trustee is reasonably satisfied as to the financial and
professional qualifications of such third party. The certificate(s) for the
Purchased Shares shall bear an appropriate legend with respect to this
requirement. Buyer will grant to the Trustee a right of first refusal to buy the
Purchased Shares and any other capital stock and rights to acquire capital stock
of McM on the same terms and at the same price offered to any third party by
Buyer. If Buyer receives an offer to purchase the Purchased Shares or any other
capital stock or rights to acquire capital stock of McM from a third party which
Buyer is willing to accept, Buyer shall give the Trustee written notice of such
offer describing the terms and the price of such offer. The Buyer shall be free
to transfer such Purchased Shares or other capital stock or rights to such third
party on the terms described in such notice unless Buyer receives written notice
from the Trustee, within 5 business days after the delivery of Buyer's notice
described above, indicating that Trustee is exercising its right of first
refusal. Buyer shall also be free to transfer such Purchased Shares, capital
stock or other rights to such third party on the terms described in Buyer's
notice to the Trustee, if within 15 days after the Trustee indicates to Buyer
its desire to exercise its right of first refusal, the transaction between the
Trustee and Buyer is not closed due to no fault of Buyer.

         (d)      If Buyer makes an offer in writing to the Trust to purchase
the Retained Shares at a price in cash that has been determined by a nationally
recognized investment banking firm reasonably acceptable to the Trustee to be
fair from a financial point of view to the Trust as majority shareholder of McM
but which in no event shall be less than $3.65 per share, and if the Trustee
declines to accept such offer within twenty business days after such offer is
made, the Trustee shall, within five business days after the expiration of the
period for acceptance of the offer, pay to Buyer an amount equal to the original
principal amount of the Fund. If the Trustee accepts such offer (subject to
approval of Court of Chancery of the State of Delaware having jurisdiction over
the Trust, if required) within such twenty day period and if the price offered
for the Retained Shares is greater than the original principal amount of the
Fund, Buyer shall pay to the Trustee within five business days after expiration
of the period for acceptance of the offer an amount equal to the difference
between the price offered for the Retained Shares and the original principal
amount of the Fund plus interest on the original principal amount of the Fund at
a rate of 6% per annum from the date the Trust received the Fund to and
including the date of payment by Buyer for the Retained Shares, and the Trustee
shall transfer the Retained Shares to Buyer free and clear of all claims, liens,
and encumbrances. If the Trustee accepts such offer within such twenty day
period and if the price offered for the Retained Shares is less than the
original principal amount of the Fund, Buyer shall have no obligation to pay any
additional amount to the Trust for the Retained Shares, the Trustee shall not be
obligated to refund any portion of the Fund to Buyer, and the Trustee shall
transfer the Retained Shares to Buyer free and clear of all claims, liens, and
encumbrances within five business days after expiration of the period for
acceptance of the offer.

         (e)      If the Buyer does not make an offer to purchase the Retained
Shares, the Trustee shall retain the Fund subject to the provisions of paragraph
2 of this Agreement.
