Gentlemen:

         This letter shall set forth our agreement with respect to services to
be provided by Keating Investments, LLC ("Keating") to Imsco Technologies, Inc.
("Imsco"), in connection with the proposed equity financing of $1,500,000 by
Trilium Holdings Ltd. ("Trilium"), which such entity was first introduced to
Imsco by Keating ("Transaction"). We hereby agree as follows:

         1. SERVICES. Imsco agrees to pay Keating the fees set forth in
Paragraph 2 with respect to the Transaction upon confirmation of receipt of
funds from Trilium.

         2. COMPENSATION. As compensation for the assistance described above,
Imsco agrees to pay Keating, upon the closing of the Transaction, an amount
equal to ten percent (10.0%) of the investment made by Trilium.

         3. TERM. This retention of Keating by Imsco hereunder shall commence on
the date hereof and shall continue until terminated by either party immediately
upon written notice to the other or, if earlier, the termination or abandonment
of the Transaction.

         4. INDEPENDENT CONTRACTOR. Keating shall at all times act as and be an
independent contractor, and in no event shall either Keating or any of its
employees, agents or representatives be deemed to be an employee, agent or
representative of Imsco. Keating shall have no authority to bind Imsco to any
obligation, express or implied. Imsco acknowledges that a principal of Keating,
Timothy J. Keating, is the sole director and officer of Imsco, but that Imsco
has determined that the compensation arrangement described herein is fair to
Imsco and similar to terms that would apply in an arm's-length transaction under
the circumstances.

         5. MISCELLANEOUS. This agreement constitutes the entire agreement of
the parties pertaining to the subject matter hereof, and the parties have made
no agreements, representations or warranties relating to the subject matter of
this agreement that are not set forth herein or therein. This agreement may not
be modified, amended or waived in any matter except by an instrument in writing
signed by each of the parties hereto. The waiver by either party of compliance
with any provision of this agreement by the other party shall not operate or be
construed as a waiver of any other provision of this agreement, or of any other

breach by such party of a provision of this agreement. Neither party may assign
its rights or obligations hereunder. This agreement shall be governed by and
construed in accordance with the laws of the State of Delaware, without regard
to the conflicts of laws principles thereof. Neither party shall take any action
with the intention or result that such action directly or indirectly circumvents
the intentions or provisions hereof.

         If the foregoing represents our agreement, please sign both copies of
this agreement where indicated below and return them to me.

                               Sincerely,

                               IMSCO TECHNOLOGIES, INC.

its expense, within 75 days of the Closing, use its commercially reasonable
efforts to file a registration statement on the appropriate form (the
"Registration Statement") with the SEC (the "SEC Filing") seeking to permit the

                           (a) Keep such registration effective for a period of
         twelve (12) months provided, however, that (i) such twelve (12) month
         period shall be extended for a period of time equal to the period
         Investor refrains from selling any shares of Common Stock included in
         such registration at the request of an underwriter of securities of the
         Company or at the request of the Company or an Exchange, and (ii) in
         the case of any registration of securities on Form S-3 or comparable
         successor form which are intended to be offered on a continuous or

<PAGE>

         in the Registration Statement. Investor agrees that it will refrain
         from selling any shares included in such Registration Statement at the
         request of the Company due to the Company's failure to have a current
         prospectus included as a part thereof, provided the Company shall use

         become current;

         prospectus and each amendment or supplement thereto in both electronic
         and print format, and (ii) such number of copies of a prospectus,
         including a preliminary prospectus, and all amendments and supplements
         thereto, and such other documents as Investor may reasonably request in
         order to facilitate the disposition of the shares of Common Stock owned
         by Investor;

                           (d) Notify Investor at any time when a prospectus
         relating thereto is required to be delivered under the Securities Act,
         of the happening of any event as a result of which the prospectus
         included in such Registration Statement, as then in effect, includes an
         untrue statement of a material fact or omits to state a material fact
         required to be stated therein or necessary to make the statements
         therein not misleading or incomplete in light of the circumstances then
         existing, and at the request of Investor, prepare and furnish to it a
         reasonable number of copies of a supplement to or an amendment of such
         prospectus as may be necessary so that, as thereafter delivered to
         Investor, such prospectus shall not include an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein not misleading or
         incomplete in light of the circumstances then existing;

                           (e) Use its reasonable best efforts to prevent the
         issuance of any stop order or other suspension of effectiveness of a
         Registration Statement, and, if such an order is issued, to obtain the
         withdrawal of such order at the earliest possible moment and to notify
         Investor (or, in the event of an underwritten offering, the managing
         underwriters) of the issuance of such order and the resolution thereof;

         applicable rules and regulations of the SEC, and make available to
         Investor, as soon as reasonably practicable, an earnings statement
         covering the period of at least twelve (12) months, but not more than
         eighteen (18) months, beginning with the first month after the
         effective date of the Registration Statement, which earnings statement
         shall satisfy the provisions of Section 11(a) of the Securities Act;
         and

                           (j) Hold in confidence and not make any disclosure of

         expense, undertake appropriate action to prevent disclosure of, or to
         obtain a protective order for, such information.

                           (a) To the extent that Investor includes any shares

                           (a) The Investor has sufficient liquid assets to
         sustain a loss of the Investor's entire investment.

                           (b) The Investor has such knowledge and experience in
         financial, investment and business matters that it is capable of
         evaluating the merits and risks of the prospective investment in the
         securities of the Company. The Investor has consulted with such
         independent legal counsel or other advisers as it has deemed
         appropriate to assist the Investor in evaluating its proposed
         investment in the Company.

                           (c) The Investor represents that it (i) has adequate
         means of providing for its current financial needs, and has no need for
         liquidity of investment in the Company; and (ii) can afford (a) to hold
         unregistered securities for the period of time required and (b) to
         sustain a complete loss of the entire amount of the Investment.

                           (d) The Investor acknowledges that the offering of
         Units has not been registered under the Securities Act in reliance on
         an exemption for transactions by an issuer not involving a public
         offering, and further understands that the Investor is purchasing the
         Units without being furnished any prospectus setting forth all of the
         information that would be required to be furnished under the Securities
         Act.

                           (e) The Units and components thereof being purchased
         are being acquired solely for the account of the Investor for
         investment purposes and not with a view to, or for resale in connection
         with, any distribution in any jurisdiction where such sale or
         distribution would be precluded, provided that Investor may offer
         participations in the Units to its principals who purchase
         contemporaneous with Investor.

                           (f) The Investor has been afforded the opportunity to
         ask questions of, and receive answers from, the officers and/or
         directors of the Company concerning the terms and conditions of this
         transaction and to obtain any additional information, to the extent
         that the Company possesses such information or can acquire it without
         unreasonable effort or expense, necessary to verify the accuracy of the
         information furnished; and has availed himself of such opportunity to
         the extent he considers appropriate in order to permit him to evaluate
         the merits and risks of an investment in the Company. It is understood
         that all documents, records and books pertaining to this investment
         have been made available for inspection, and that the books and records
         of the Company will be available upon reasonable notice for inspection
         by investors during reasonable business hours at its principal place of
         business.

                                       15
<PAGE>

the name of the Holder, shall be delivered to the Holder hereof as soon as
practicable after the rights represented by this Warrant shall have been so
exercised.

         (c) At any time prior to the Termination Date, the Holder may, at its
option, exchange this Warrant, in whole or in part (a "Warrant Exchange"), into
the number of Warrant Shares determined in accordance with this Section, by
surrendering this Warrant at the principal office of the Corporation,
accompanied by a notice stating such Holder's intent to effect such exchange,
the number of Warrant Shares to be exchanged and the date on which the Holder
requests that such Warrant Exchange occur (the "Notice of Exchange"). The
Warrant Exchange shall take place on the date specified in the Notice of
Exchange or, if later, within ten (10) days of the date the Notice of Exchange
is received by the Corporation (the "Exchange Date"). Certificates for the
shares issuable upon such Warrant Exchange and, if applicable, a new warrant of
like tenor evidencing the balance of the shares remaining subject to this
Warrant, shall be issued as of the Exchange Date and delivered to the Holder
within five (5) business days following the Exchange Date. In connection with
any Warrant Exchange, this Warrant shall represent the right to subscribe for
and acquire the number of Warrant Shares (rounded to the next highest integer)
equal to (1) the number of Warrant Shares specified by the Holder in its Notice
of Exchange (the "Total Number") less (2) the number of Warrant Shares equal to
the quotient obtained by dividing (a) the product of the Total Number and the
existing Warrant Price by (b) the Market Price of a share of Common Stock, as
defined in the next sentence. As used herein, the phrase "Market Price" at any
date shall be deemed to be the last reported sale price, or, in case no such
reported sale takes place on such day, the average of the last reported sale
prices for the last three trading days, in either case as reported by the
principal securities exchange on which the Common Stock is listed or admitted to
trading or as reported by NASDAQ, or if the Common Stock is not listed or
admitted to trading on any national securities exchange or quoted on NASDAQ, the
closing bid price on the NASDAQ Electronic Bulletin Board or as otherwise
furnished by the National Association of Securities Dealers, Inc. (the "NASD")
or similar organization if the NASD is no longer reporting such information, or,
if no such bid information is reported, as determined in good faith by
resolution of the Board of Directors of the Company.

         2. RESERVATION OF WARRANT SHARES. The Corporation agrees that, prior to
the expiration of this Warrant, it will at all times have authorized and in
reserve, and will keep available, solely for issuance or delivery upon the
exercise of this Warrant, such number of Warrant Shares issuable by the
Corporation upon the exercise of this Warrant.

         3. NO STOCKHOLDER RIGHTS. This Warrant shall not entitle the holder
hereof to any voting rights or other rights as a shareholder of the Corporation.

                                       16

         4. SPLIT OR COMBINATION OF COMMON STOCK AND STOCK DIVIDEND. In case the
Corporation shall at any time subdivide, redivide, recapitalize, split or change
its outstanding shares of Common Stock into a greater number of shares or
declare a dividend upon its Common Stock payable solely in shares of Common
Stock, the Warrant Price shall be proportionately reduced and the number of
Warrant Shares proportionately increased. Conversely, in case the outstanding
shares of Common Stock of the Corporation shall be combined into a smaller
number of shares, the Warrant Price shall be proportionately increased and the
number of Warrant Shares proportionately reduced. Notwithstanding the foregoing,
in no event will the Warrant Price be reduced below the par value of the Common
Stock.

         5. MERGER OR REORGANIZATION, ETC. If at any time prior to the exercise
of this Warrant, there shall be (i) a reorganization (other than a combination,
reclassification, exchange or subdivision of stock otherwise provided for
herein), (ii) a merger or consolidation of the Corporation with or into another
corporation in which the Corporation is not the surviving entity, or a reverse
triangular merger in which the Corporation is the surviving entity but the
shares of the Corporation's capital stock outstanding immediately prior to the
merger are converted by virtue of the merger into the property, whether in the
form of securities, cash, or otherwise, or (iii) a sale or transfer of the
Corporation's properties and assets as, or substantially as, an entirety to any
other person, then, as a part of such reorganization, merger, consolidation,
sale or transfer, lawful provision shall be made so that the Holder shall
thereafter be entitled to receive upon exercise of this Warrant, the number of
shares of stock or other securities or property of the successor corporation
resulting from such reorganization, merger, consolidation, sale or transfer that
Holder would have been entitled to receive in such reorganization,
consolidation, merger, sale or transfer if this Warrant had been exercised
immediately before such reorganization, merger, consolidation, sale or transfer.

         6. LEGEND AND STOP TRANSFER ORDERS. Unless the Warrant Shares have been
registered under the Securities Act, upon exercise of any part of the Warrant,
the Corporation shall instruct its transfer agent to enter stop transfer orders
with respect to such Warrant Shares, and all certificates or instruments
representing the Warrant Shares shall bear on the face thereof substantially the
following legend, insofar as is consistent with Delaware law:

                  THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE SOLD OR
                  TRANSFERRED WITHOUT AN EFFECTIVE AND CURRENT REGISTRATION
                  STATEMENT OR POST-EFFECTIVE AMENDMENT THERETO FOR SUCH SHARES
                  UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR AN OPINION OF
                  COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER THAT
                  REGISTRATION IS NOT REQUIRED UNDER THAT ACT.

         7. MISCELLANEOUS. This Warrant shall be governed by and construed in
accordance with the laws of the State of Delaware. All the covenants and
provisions of this Warrant by or for the benefit of the Corporation shall bind
and inure to the benefit of its successors and assigns hereunder. Nothing in
this Warrant shall be construed to give to any person or corporation other than
the Corporation and the holder of this Warrant any legal or equitable right,
remedy or claim under this Warrant. This Warrant shall be for the sole and
exclusive benefit of the Corporation and the holder of this Warrant. The section
headings herein are for convenience only and are not part of this Warrant and

                                       17
<PAGE>

shall not affect the interpretation hereof. Upon receipt of evidence
satisfactory to the Corporation of the loss, theft, destruction or mutilation of
this Warrant, and of indemnity reasonably satisfactory to the Corporation, if
lost, stolen or destroyed, and upon surrender and cancellation of this Warrant,
if mutilated, the Corporation shall execute and deliver to the Holder a new
Warrant of like date, tenor and denomination.

         IN WITNESS WHEREOF, the Corporation has caused this Warrant to be
executed by its duly authorized officers under its seal, as of this 10th day of
July, 2001.
