         Re:   IMSI Shareholders v. Wynn Westmoreland, et al.
               Civil No. 990908831 (Hon. Peuler)

Dear Peter:

         This binding letter agreement embodies the parties' understanding of
the core terms of a settlement intended to resolve certain claims in the current
litigation. These core terms are subject to a more detailed memorialization in a
formal Settlement Agreement which I intend to draft and present to you for your
review once this letter agreement has been signed by the parties. In addition,
as you know, this settlement is subject to Court approval. This letter agreement
shall be null and void if the Settlement Agreement is not approved by the Court
despite the parties' best efforts to obtain such approval.

         1. IMSI will ratify and issue to Eagle or, at Eagle's election, to
Great Wall New Buildings Systems, Inc. ("GWNBS"), Construction Technologies of
India, Inc. ("CT India"), and/or Construction Technologies of Mexico, Inc. ("CT
Mexico") the licenses for China, India, and Mexico, subject to the additional
terms set forth below. Prior to issuance of a license to GWNBS, CT India or CT
Mexico, any such entity must execute a license agreement containing, among other
things, an obligation to pay royalties in the amount and on the schedule set
forth in paragraph 4 below. Eagle represents and warrants that no remaining
Defendant (a) is an officer or director of GWNBS, CT India or CT Mexico, or (b)
directly or indirectly owns a controlling interest in GWNBS, CT India or CT
Mexico. Eagle further represents and warrants that it will not sell any
ownership interests in GWNBS, CT India or CT Mexico to such individuals and
entities until the conclusion of the current litigation as defined in paragraph
5 below. As set forth in the releases described in paragraph 14 below,
plaintiffs expressly waive any claim they may have to the ownership interest

- ----------------------------

Eagle now holds in GWNBS, CT India and CT Mexico and will not seek to recover
such ownership from Eagle for claims covered by that release. Eagle will pay
$25,000.00 for each of these three licenses into an escrow fund designated by
plaintiffs. This payment will be made by Eagle within three business days from
the date that the Settlement Agreement is executed by the parties. Plaintiffs
agree that they will not access the funds paid into the escrow fund under this
letter agreement and the Settlement Agreement until the Settlement Agreement is
approved by the Court, and that all funds withdrawn from the escrow fund will be
used by plaintiffs for IMSI-related expenses only. If the Settlement Agreement
is not approved by the Court despite the parties' best efforts, all funds in
escrow paid by Eagle shall be returned to Eagle. The parties agree to enter into
a mutually acceptable license agreement for each of these three licenses
containing language consistent with this letter agreement and the Settlement
Agreement, as well as other terms agreed upon by the parties.

         2. IMSI will ratify the existing license for Romania held by Advantage
Technologies. Eagle agrees to pay royalties on this license as set forth below.
The parties agree to enter into a mutually acceptable license agreement for this
license which contains language consistent with this letter agreement and the
Settlement Agreement, as well as other terms agreed upon by the parties.

         3. IMSI and Eagle will enter into a mutually acceptable license
agreement for a new license territory which contains language consistent with
this letter agreement and the Settlement Agreement, as well as other terms
agreed upon by the parties. This license is referred to herein as the
"Southeastern Europe" license. The geographic scope of this license will be the
countries of Turkey, Croatia, Bosnia, and Kosovo. The license fee for this
license will be $50,000.00. Eagle agrees to pay this amount into the escrow fund
described in paragraph 1 above within three business days from the date that the
Settlement Agreement is executed by the parties. Eagle agrees to obtain within
ten days of the execution of this letter agreement Mr. Wayne Johnson's release
of claims to the allegedly pre-existing "Balkans" license on behalf of Mr.
Johnson and any entity which he owns or controls or which claims ownership of
the pre-existing "Balkans" license, and to indemnify and defend IMSI against any
claims brought by Wayne Johnson or any entity owned or controlled by him against
IMSI relating to the pre-existing "Balkans" license.

         4. Eagle will pay to IMSI royalties of 4.5% of gross revenues generated
in any of its license territories. The license territories are as identified
herein. Gross revenues will be broadly defined as all revenues generated by
Eagle on the sale of any IMSI-related products, which shall by defined as any
product which incorporates the patents or other intellectual property of IMSI,
including but not limited to the IMSI Block system, the associated patents, the
associated trademarks, the surface coating system (also known as Q-Bond, the
ownership of which is at issue in the current litigation), and the inserts. As
to be set forth more specifically in the respective license agreement for each
of the five licenses described herein, Eagle agrees that it will not seek to
circumvent its royalty obligations by selling or otherwise transferring
IMSI-related products at less than fair market value. To the extent not paid in
the 4.5% royalty described herein, Eagle will pay minimum royalties as follows:

         Balkans:          April 2000 through September 2000, $2,000.00 per

                           per month; and $7,500 per month from and including
                           October 2001 onward.

         Mexico:           July 2000 through December 2000, $2,000.00 per month;
                           January 2001 through June 2001, $2,500.00 per month;
                           July 2001 through December 2001, $5,000.00 per month;
                           and $7,500 per month from and including January 2002
                           onward.

These royalties will be paid into the escrow fund described in paragraph one
above. In the event that Eagle fails to pay the minimum royalty for any license
by the last day of the month in which it is due, IMSI agrees to provide written
notice of such default, and Eagle shall have thirty days after written notice to
cure the default. In the event that Eagle fails to cure its default, Eagle
agrees that it will forfeit that license and will be subject to collection
proceedings by IMSI. Eagle agrees to pay IMSI its reasonable attorneys' fees and
costs incurred in such collection proceedings and to pay interest on past-due
royalties in the amount of 10% per annum.

         5. Eagle agrees that, from the date of its signature on this letter
agreement, it will not engage in IMSI-related business, including sales,
marketing and all other aspects of IMSI-related business, directly or indirectly
through joint venture partners or existing IMSI licensees, in any location other
than the countries of China, India, Mexico, Romania, Turkey, Kosovo, Croatia,
and Bosnia, until the earliest of the following: (1) the conclusion of this
litigation (signified by entry of a final, non-appealable Order in the case
number set forth above); (2) January 1, 2002; or (3) written approval in advance
by IMSI's Board. Eagle further agrees that it will not engage in IMSI-related
business in any of the eight countries designated in this paragraph if the IMSI
license which covers each such country is not in good standing. Good standing
shall mean that the minimum royalties for the relevant license are current, and
all other obligations of the licensee under the license agreement are being
satisfactorily performed by the licensee. In the event that Eagle engages in
IMSI-related business in violation of this paragraph, Eagle agrees that IMSI is
entitled to injunctive relief and to its reasonable attorneys' fees and costs in
pursuing such injunctive relief.

         6. Eagle agrees that, until the conclusion of the current litigation
(as defined above), Eagle and its officers, directors, and agents will not
knowingly sell any IMSI shares or Eagle shares to Wynn Westmoreland, Richard
Anderson, or Michael Smith, to any entity which Wynn Westmoreland, Richard
Anderson, or Michael Smith owns or controls, directly, indirectly, or
beneficially, or to any relatives of Wynn Westmoreland, Michael Smith, or
Richard Anderson. The parties acknowledge that Eagle cannot stop these
individuals and entities from acquiring stock in the open market or through a
public offering. Eagle agrees, however, that, in addition to its other
obligations set forth in this paragraph, Eagle and its officers, directors, and
agents will not offer stock in any Eagle public offering to Wynn Westmoreland,
Richard Anderson, or Michael Smith, to any entity which Wynn Westmoreland,
Richard Anderson, or Michael Smith owns or controls, directly, indirectly, or
beneficially, or to any relatives of Wynn Westmoreland, Michael Smith, or
Richard Anderson on terms that are more favorable than any other member of the
public seeking to buy such shares through a public offering.

         7. The "lock-up" agreement which is attached hereto as Exhibit A is
incorporated as part of this letter agreement. Eagle agrees that it will not
alter or permit to be altered the terms of the lock-up agreement without the
prior written consent of Dr. Strobel and Mr. Hermanson. To the extent that
persons or entities related to or controlled by the remaining defendants
received Eagle shares or (b) interests in IMSI joint ventures or other
enterprises (including but not limited to GWNBS, CT India, and CT Mexico), and
that such persons have not signed the lock-up agreement, Eagle agrees not to
oppose any effort by plaintiffs to obtain a court order to lock up such shares.
The parties agree that unrestricted Eagle shares received through an exchange of
IMSI shares or shares in an IMSI-related joint venture or other enterprise for
which cash was paid at fair market value are not subject to the lock-up
requirement. In the event that plaintiffs provide verifiable evidence that fair
market value was not paid for any such shares, Eagle agrees not to oppose an
effort by plaintiffs to obtain a court order to lock up the equivalent Eagle
shares and, if IMSI shares are involved, Eagle agrees that such IMSI shares will
be returned to IMSI by Eagle. Eagle agrees to provide to plaintiffs all
information in its possession which may be relevant to the terms of this
paragraph.

         8. Eagle hereby assigns to IMSI whatever rights Eagle gained to the
IMSI Block System through its assignment agreement with Stan and Weldon Johnson.
Eagle further agrees and stipulates that it has no ownership interests in the
IMSI Block System or IMSI's other intellectual property and assets other than
whatever rights Eagle has as an IMSI licensee and shareholder.

         9. Eagle agrees not to seek reimbursement of funds it paid on behalf of
IMSI, including but not limited to funds paid to Stan and Weldon Johnson by
Eagle. Eagle will provide to plaintiffs within a reasonable time all documents
and other information sought by plaintiffs relating to funds paid by Eagle on
behalf of IMSI.

- ----------------------------


         10. Eagle (including its officers directors and authorized agents) will
not solicit, purchase or otherwise acquire any additional IMSI shares or right
to such shares until conclusion of the current litigation (as defined above).
Eagle represents that it will not authorize Michael Smith, Wynn Westmoreland, or
Richard Anderson (or entities controlled by or owned in whole or in part by any
of them) to solicit, purchase or otherwise acquire additional IMSI shares or
rights to such shares for, on behalf of, or for the benefit of Eagle or to take
any other actions on behalf of Eagle which would violate this letter agreement
or the Settlement Agreement. Based on that representation, plaintiffs
acknowledge that Wynn Westmoreland, Michael Smith, and Richard Anderson are not
future agents of Eagle for those purposes. Eagle is not admitting by this letter
agreement that any of these individuals have been or are agents of Eagle, and
subject to the release of Eagle described in paragraph 14 below plaintiffs are
not precluded from raising allegations in the current litigation that the
remaining defendants conspired with or otherwise involved Eagle for improper
purposes to the detriment of plaintiffs. Except for any IMSI shares Eagle may
have obtained from Joy and/or Cheryl Ray, Eagle further agrees that it will not
sell or transfer any of its currently held IMSI shares without the prior written
approval of Dr. Rudolf Strobel and Craig Hermanson until the conclusion of the
current litigation (as defined above). With respect to the shares Eagle may have
obtained from Joy and/or Cheryl Ray, plaintiffs will not preclude Eagle from
seeking to exchange any such shares for the Eagle shares Eagle may have
transferred to Joy and/or Cheryl Ray as part of any such share exchange. In the
event of such a transfer of IMSI shares from Eagle to Joy and/or Cheryl Ray,
Eagle shall provide to counsel for plaintiffs copies of all documents relating
to the exchange.

         11. If plaintiffs obtain a judgment against Smith, Westmoreland, and/or
Anderson concerning their conduct as officers or directors of IMSI, Eagle, at
the request of plaintiffs, will vote any IMSI shares it owns or controls to
remove such individual(s) as officers and directors.

         12. In the event that plaintiffs or IMSI obtain a judgment which holds
that any of the IMSI shares now held by Eagle were improperly issued or
retained, Eagle agrees to return those specified shares to IMSI without
compensation from IMSI. The parties agree that Eagle does not waive its right to
seek compensation from the person or persons who exchanged such IMSI shares for
Eagle shares. In the event there is a settlement by which one or more of the
defendants agree that any IMSI shares were improperly issued or retained by any
or all of them (or by entities owned or controlled by any or all of them), Eagle
will return those shares to IMSI upon the tender to Eagle of the corresponding
Eagle shares. With respect to ownership interests in GWNBS, CT India and CT
Mexico which Eagle obtained from the remaining defendants, plaintiffs will not
seek to recover such interests from Eagle for any claim subject to the release
described in paragraph 14 below. Plaintiffs are not precluded from seeking any
corresponding Eagle shares in satisfaction of a judgment against, or settlement
with, any of the remaining defendants.

- ----------------------------

         13. Eagle agrees that, until the conclusion of the litigation (as
defined above), Eagle will not vote any IMSI shares which it owns or controls
toward retaining or removing any existing member of IMSI's Board or toward
appointing any new IMSI Board member without the prior written approval of Craig
Hermanson and Dr. Rudolf Strobel. Eagle further agrees that during the pendency
of the current litigation, it will not vote any IMSI shares which it owns or
controls to terminate the current litigation or any aspect of it without the
prior written approval of Dr. Strobel and Mr. Hermanson. Plaintiffs agree that
they will not initiate a shareholding meeting for purposes of retaining,
removing or electing members to IMSI's Board without Eagle's consent for six
months from the date of this letter agreement. However, plaintiffs are not
precluded from removing at any time any IMSI Board member without Eagle's
consent through an order of a court of competent jurisdiction or through a
settlement or other agreement with any such IMSI Board member.

         14. The parties agree to execute mutual releases. Eagle will be
dismissed from the current litigation with prejudice. Eagle will drop its
counterclaims with prejudice. Plaintiffs and Eagle will each bear their own
respective attorneys' fees and costs.

         15. Despite being dismissed from the litigation, Eagle will produce any
otherwise discoverable documents without a subpoena, provided plaintiffs pay any
copying costs. Eagle also will produce witnesses under its control without a
subpoena, provided that plaintiffs pay any travel expenses or other out of
pocket costs, such expenses and costs to be reasonable and approved by
plaintiffs' counsel prior to being incurred. Eagle agrees to provide plaintiffs
with all documents, information, and witnesses relating to exchanges of IMSI
stock for Eagle stock, all transactions relating to any IMSI-related joint
venture, and all transactions with any other defendant in this matter. Eagle
also agrees that it will produce information and documents relating to all
communications with present or former IMSI shareholders. Eagle also will provide
plaintiffs with information and documents relating to all past, present, or
future funds that Eagle has paid, is paying, or is obligated to pay to Wynn
Westmoreland or any entity owned or controlled (in whole or in part) by
Westmoreland or any member of Westmoreland's family. Eagle will not seek
reimbursement for lost time or any associated legal fees in performing these
tasks, but plaintiffs agree to pay any reasonable out of pocket costs incurred
by Eagle in complying with plaintiffs' requests for documents or witnesses, such
costs to be approved by plaintiffs' counsel prior to being incurred by Eagle.

         16. Eagle agrees that in the event that a Court or the IMSI Board
determines that an IMSI license was issued or retained without adequate
consideration or without proper IMSI Board approval (excepting those licenses
which are included in this settlement), and that the license is therefore not in
good standing, then to the extent Eagle retains an equity interest in IMSI at
that time, Eagle will support the cancellation of each such license and
recoupment of outstanding royalty payments. Eagle also agrees that to the extent
it retains an equity interest in IMSI at that time, Eagle will support the
revocation of each license for which the licensee fails or has failed to pay
minimum royalties pursuant to that licensee's license agreement or which is
otherwise not in good standing.

- ----------------------------

         17. Eagle and the plaintiffs agree that they will take all steps
necessary for the settlement to be approved, including approval by the Court, by
IMSI's Board, and by IMSI's shareholders (if deemed necessary by the Court).

         18. The parties agree that in the event of a breach of this letter
agreement, the non- breaching party will be entitled to its reasonable
attorneys' fees and costs arising out of or in connection with such breach,
whether incurred with or without litigation, on appeal, or otherwise.

                                                     Sincerely,



                                                     Jonathan O. Hafen
