($1,000,000), shall upon presentation of this Certificate for endorsement of any
partial payment, or upon complete surrender for cancellation in return for final
payment in full, be payable no later than December 31, 2000, by OF&C at its Home

             reserves, reinsurance, policyholder dividends, production and
             administrative expenses, taxes, loans and advances), but excluding

   2



         (2) An amount (of surplus) equal to the larger of (a) or (b)
hereinafter:

                  (a) The amount required by the laws of North Carolina at the
                  time of such repayment for the issuance of a Certificate of
                  Authority to transact the classes of insurance which it is
                  then transacting anywhere, or which it is authorized to
                  transact in North Carolina, or the amount required by the laws
                  of any other jurisdiction for the retention of its Certificate
                  of Authority in that jurisdiction, whichever is the largest
                  amount; or

                  (b) The amount required in order to maintain capital and
                  surplus at a level of $500,000 above the Company Action Level

                                       III

         The Principal Sum of this Certificate shall not be payable in whole or
in part, except upon approval of a majority of the Directors of OF&C made and
recorded at a regular or special meeting; provided, however, that the Directors
of OF&C shall be required to vote payment of such Principal Sum, either in whole
or in part, whenever the condition of OF&C is such that it meets the
requirements of Paragraph II; provided, further, that in no event shall the
principal sum be payable in whole or in part except upon approval in writing by
the Commissioner of Insurance.

                                       IV

         Interest at the rate of 5.0% per annum,, not compounded, shall be due
and payable quarterly by OF&C, at its Home Office, upon the unpaid balance of
the Principal Sum of this Certificate to the extent, and only to the extent,
that funds of OF&C exist on each such due date to (a) discharge all liabilities
within the meaning of Paragraph II (2) hereinabove plus that amount of surplus
required by the laws of any jurisdiction in which it is licensed to do business
to retain unimpaired its Certificate of Authority there and (b) such amounts
have been approved in writing by the Commissioner of Insurance. If no funds in
whole or in part exist on any such date, such interest for which no funds for
payment exist shall not become due or payable but shall accrue and shall become
due and payable when and to the extent such funds do come into existence
thereafter


   3



and such amounts have been approved in writing by the Commissioner of Insurance.
Any interest both due and payable by the terms of this paragraph shall create a
cause of action in the contributor and be a liability of OF&C.

                                        V

         The obligations evidenced by this Certificate shall not be a liability
or claim against OF&C or its funds or assets at any time except to the extent
that the Principal Sum hereof, in whole or in part, shall be due and payable in
accordance with the provisions of Paragraphs II and III hereof and except to the
extent that interest on this Certificate, in whole or in part, shall be due and
payable in accordance with the provisions of Paragraph IV hereof. The
Contributor shall have no right of offset for amounts due under this Certificate
of Contribution with regard to any reinsurance balances due or to become due or
against any other obligations owed OF&C by Contributor.

                                       VI

         Should OF&C at any time discontinue the insurance business, then, after
the payment or provisions for payment of all the obligations described in
subdivision (1) of Paragraph II hereof, following the determination of such
facts by the Commissioner of Insurance of the State of North Carolina, any
remaining funds or assets of OF&C shall first be applied to the payment of any
interest accrued hereon, then to the remaining unpaid balance of the Principal
Sum of this Certificate.

                                       VII

         Should, at any time during the term of this Certificate, OF&C and/or
its parent, McM Corporation, enter into a definitive agreement to sell or
otherwise participate in a transaction for the transfer of a significant portion
(20% or more) of the stock or assets of OF&C and/or McM Corporation to a party
other than the Contributor, then the maturity of this Certificate shall


   4



accelerate to the date of such definitive agreement, and the interest rate
specified in Paragraph IV shall be modified ab initio to Fifteen Percent (15.0%)
per annum.

                                      VIII

         It is understood and agreed that the Contributor has made the foregoing
contribution upon the terms and conditions herein set forth, after having been
furnished with a copy of the approval of the Commissioner of Insurance of the
State of North Carolina authorizing the issuance of this Certificate and having
read the same, and that this Certificate evidences the complete understanding
and agreement between the Contributor and OF&C.
