Dear Ms. Peterson:

               Re:  SuperCorp Inc. and Engineering and Materials Technology
                    Corporation merger-spinoff

         I earlier advised you of a proposed merger-spinoff transaction pursuant
to an agreement that SuperCorp has entered into with Engineering & Materials
Technology Corporation, an Oklahoma corporation that provides an array of
engineering and consulting services related to equipment failure analysis,
accident investigation, and quality-control assurance testing and monitoring.

         We shall soon be filing the necessary registration statements with the
Securities and Exchange Commission.

         There is a requirement that I must address at this time. It concerns
the possibility - which is not the probability - that the interest owners of
Engineering and Materials Technology Corporation should vote to disapprove the
                                                                ----------
merger-spinoff proposal.

         I enclose several pages of the present draft of the registration
statements being prepared for filing with the Securities and Exchange
Commission. You will see a section entitled "Consequences Should the Merger Not
Occur." Described in this section is a rather complex arrangement which is
required by Rule 419 of the Securities and Exchange Commission. Such rule
relates to companies known as "blank check companies." While the company created
by SuperCorp (referred to in the enclosed draft as "the Company") is not a
classic "blank check company" as envisioned by the Securities and Exchange
Commission, I do believe that the

Company, prior to the merger, falls under the requirements of Rule 419.
Accordingly, it will be necessary to comply with such rule, and the rule
requires that if the Company does not acquire a business or assets that would
constitute a business within eighteen months after the registration statement
becomes effective, the shares of stock of the Company are not to be let loose
into the public market. I believe that a satisfactory way of complying with the
rule is to have the holders of the majority of the Company's common stock agree
at this time that they will vote to dissolve the Company (remember: the Company
is not SuperCorp but a company created by SuperCorp) if no merger or business
acquisition occurs within eighteen months after the effective date of the
registration statement.

         I believe that the enclosed materials explain this matter. A letter
identical to this letter is being sent to persons whose shareholdings of
SuperCorp aggregate more than 50 percent of its outstanding shares and who will
receive more than 50 percent of the shares of the Company whose shares are being
spun off.

         I ask that you and each of such persons execute where indicated below a
copy of this letter and return it to me, indicating thereby that, should the
proposed merger between Engineering and Materials Technology Corporation and
EMTC International, Inc. not be effected, and should EMTC International, Inc.
not acquire a business or assets that would constitute a business within
eighteen months after the effective date of the registration statement to be
filed with the Securities and Exchange Commission, you will vote to cause a
dissolution of EMTC International, Inc. or comply with any similar alternative
requirement that might be proposed by the Securities and Exchange Commission to
effect compliance with its Rule 419.

         I appreciate your cooperation. Should you not agree to the matters set
forth herein, it is likely that the transaction with Engineering and Materials
Technology Corporation will have to be abandoned.

                                   Sincerely,

                                   /s/ Thomas J. Kenan

                                   Thomas J. Kenan

Enclosures

         The undersigned agrees to the matters set forth in the above letter.
