                                TENDER AGREEMENT

         THIS TENDER 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 the
persons listed on SCHEDULE A hereto (each, individually a "Shareholder" and,
collectively, the "Shareholders").

                              BACKGROUND STATEMENT

         Buyer desires to acquire approximately 49% of the issued and
outstanding shares ("Shares") of common stock, par value $1.00 per share (the
"Common Stock"), of McM Corporation ("McM"), a North Carolina corporation
headquartered in Raleigh, North Carolina, through the acquisition of
approximately 14% of such Shares from the McMillen Trust (the "Trust") and a
tender offer (the "Offer") to purchase up to 35% of such Shares for $3.65 per
share net to the sellers thereof in cash (such amount or any greater per share
amount paid in the Offer, the "Per Share Amount").

         Buyer and McM have entered into an Offer and Rights Agreement, dated as
of the date hereof (the "Offer and Rights Agreement"), which provides, among
other things, upon the terms and subject to the conditions thereof, for the
Offer. The Offer and Rights Agreement provides that holders of options
("Options") to purchase Shares ("Option Shares") may elect, in their sole
discretion, to cancel their Options in return for a cash payment from Buyer
equal to the Per Share Amount for each Option Share less the exercise price for
each Option Share.

         The Shareholders are each directors of McM. As of the date hereof, the
Shareholders own (beneficially or of record) the number of Shares and Options
set forth opposite such Shareholder's name on SCHEDULE A attached hereto.

         As a condition to the willingness of Buyer to enter into the Offer and
Rights Agreement, Buyer has required that the Shareholders agree, and in order
to induce Buyer to enter into the Offer and Rights Agreement, the Shareholders
have agreed, (i) to tender and not withdraw, or to cause to be tendered and not
withdrawn, pursuant to the Offer, all of the Shares listed on Schedule A hereto
and all other Shares now owned (beneficially or of record) by such Shareholders
or which may hereafter be acquired by such Shareholders (the "Tendered Shares")
and (ii) in connection with the Offer, to elect to cancel their Options in
consideration of the cash-out payment from Buyer described above.

                             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.       Tender of Shares. Subject to the terms and conditions of this
Agreement, each Shareholder agrees to validly tender and not withdraw, or to
cause to be tendered and not withdrawn, pursuant to the Offer, all of Tendered
Shares; provided, that no such tender shall be required if such Shareholder
would as a result of such tender incur liability under Section 16(b) of the
Securities Exchange Act of 1934, as amended ("Section 16(b)"). Notwithstanding
the foregoing, in the event any Shareholder fails to tender any Tendered Shares
due to Section 16(b) liability, as soon as such liability lapses with respect to
any Tendered Shares, such Shareholder agrees to tender in the Offer, or if Buyer
has accepted for payment Shares pursuant to the Offer, to sell to Buyer for the
Per Share Amount, such Tendered Shares.

         2.       Cash-Out and Cancellation of Options. Subject to the terms and
conditions of this Agreement, each Shareholder holding Options listed on
SCHEDULE A hereto ("Cash-Out Options") agrees, in accordance with the procedures
set forth in the Offer, to instruct McM to cancel all of his or her Cash-Out
Options in consideration of a cash payment by Buyer for each such Cash-Out
Option in an amount, subject to applicable withholding of taxes, equal to (x)
the product of (i) the aggregate number of Option Shares subject to such
Cash-Out Option times (ii) the Per Share Amount, minus (y) the aggregate
exercise price for all Option Shares subject to such Cash-Out Option. In
consideration of Buyer's Offer and entry into this Agreement, each Shareholder
agrees that each Cash-Out Option with a per share exercise price in excess of
the Per Share Amount ("Under Water Options"), upon Buyer's acceptance for
payment and payment for Shares validly tendered and not withdrawn pursuant to
the Offer, shall be cancelled by McM without payment by Buyer of any additional
consideration therefor.

         3.       Representations and Warranties by the Shareholders. Each
Shareholder hereby severally represents and warrants to Buyer as follows:

         (a)      At the time the Tendered Shares are tendered in the Offer,
each Shareholder, either individually or together with his spouse, will have
good and valid title to the Tendered Shares, free and clear of all restrictions,
claims, liens, charges and encumbrances.

         (b)      Each Shareholder has good and valid title to the Cash-Out
Options (including, without limitation, the Under Water Options), free and clear
of all restrictions, claims, liens, charges and encumbrances other than those
set forth in the 1986 Employee Incentive Stock Option Plan and the 1996 Employee
Incentive Stock Option Plan (together, the "Plans").

         (c)      Each Shareholder has the power, authority, and capacity to
enter into and perform its obligations under this Agreement, and to consummate
the transactions contemplated herein. This Agreement has been duly and validly
executed by each Shareholder and is the legal, valid and binding obligation of
each Shareholder, enforceable in accordance with its terms, except as
enforceability may be limited by equitable principles or by bankruptcy,
fraudulent conveyance or insolvency laws affecting the enforcement of creditors'
rights generally.

rule or regulation of any court or governmental authority having jurisdiction
over each Shareholder or any of the Tendered Shares or Cash-Out Options.

court or governmental authority having jurisdiction over Buyer or its property.

         (d)      The Tendered 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

transfer, tender, exercise, assign, hypothecate or otherwise dispose of, or
create or permit to exist any security interest, lien, claim, pledge, option,
right of first refusal, agreement, limitation on such Shareholder's voting
rights, charge or other encumbrance of any nature whatsoever with respect to
such Tendered Shares or such Cash-Out Options, or agree to do any of the
foregoing, at any time prior to the earlier of (x) the purchase by Buyer of the

such determination that any term or other provision is invalid, illegal or
incapable of being enforced, the parties hereto shall negotiate in good faith to
modify this Agreement so as to effect the original intent of the parties as
closely as possible in a mutually acceptable manner in order that the terms of
this Agreement remain as originally contemplated to the fullest extent possible.

         (h)      Except as otherwise required by applicable law, each party
