Item 4.  Purpose of Transaction

         As described more fully in Item 3 above, this statement relates to the
acquisition of 533,095 shares of Common Stock by Devma.

         On October 16, 1997, the Issuer and the Investors entered into a Stock
Exchange Agreement (the "Stock Exchange Agreement") pursuant to which each
Investor may, at any time and from time to time, exchange all or part of the
Class A or Class B common shares it holds in the capital stock of CTEK Laminates
Inc. ("CTEK") (a canadian corporation) for shares of Common Stock of the Issuer.
In addition, pursuant to the Stock Exchange Agreement, the Issuer may, only if
certain conditions are met, require all of the Investors (and not less than all
of them) to exchange all (and not less than all) of their Class A and Class B
common shares of CTEK for shares of Common Stock of the Issuer. Presently, each
Investor holds the following number and class of common shares in the capital
stock of CTEK:

         Investor                           Number of Class A common shares
         --------                           -------------------------------
         Devma                                        177,700
         Innovatech                                   177,700
         FSTQ                                         639,714
         Fonds Regional                                71,078


         In addition, pursuant to a Registration Rights Agreement between the
Issuer and the Investors dated October 16, 1997, each Investor has been granted
certain registration rights relating to the Common Stock held by it (including
any Common Stock received pursuant to its exchange rights provided in the Stock
Exchange Agreement). Such registration rights shall become effective on July 2,
1998 or such earlier date that any of the management lock-up agreements entered
into by certain shareholders of the Issuer expire. The shares of Common Stock
acquired by Devma have been acquired for the purpose of making an investment in
the Issuer and not with the present intention of acquiring control of the
Issuer's business.

         Devma intends from time to time to review its investment in the Issuer
on the basis of various factors, including the Issuer's business, financial
condition, results of operations and prospects, general economic and industry
conditions, the securities markets in general and those for the Issuer's
securities in particular, as well as other developments, and other investment
opportunities. Based upon such review, Devma will take such actions in the
future as Devma may deem appropriate in light of the circumstances existing from
time to time. If Devma believes that further investment in the Issuer is
attractive, whether because of the market price of the Issuer's securities or
otherwise, Devma may acquire shares of Common Stock or other securities of the
Issuer either pursuant to the Stock Exchange Agreement or pursuant to the
Investors' Agreement (which is more fully described hereinafter in Item 6), in
the open market or in privately-negotiated transactions. Similarly, depending on
market and other factors, Devma may determine to dispose of some or all of the
Common Stock currently owned by Devma or otherwise acquired by Devma either
pursuant to the Stock Exchange Agreement or pursuant to the Investors'
Agreement, in the open market or in privately negotiated transactions.

         Except as stated above, Devma and, to the best knowledge of Devma, all
persons listed on Schedule I have no present plans which relate to or would
result in:


<PAGE>

     (a)  The acquisition by any person of additional securities of the Issuer,
          or the disposition of securities of the Issuer;

     (b)  An extraordinary corporate transaction, such as a merger,
          reorganization or liquidation, involving the Issuer or any of its
          subsidiaries;

     (c)  A sale or transfer of a material amount of assets of the Issuer or any
          of its subsidiaries;

     (d)  Any change in the present board of directors or management of the
          Issuer, including any plans or proposals to change the number or term
          of directors or to fill any existing vacancies on the board;

     (e)  Any material change in the present capitalization or dividend policy
          of the Issuer;

     (f)  Any other material change in the Issuer's business or corporate
          structure;

     (g)  Changes in the Issuer's charter, by-laws or instruments corresponding
          thereto or other actions which may impede the acquisition of control
          of the Issuer by any person;

     (h)  Causing a class of securities of the Issuer to be delisted from a
          national securities exchange or to cease to be authorized to be quoted
          in an inter-dealer quotation system of a registered national
          securities association;

     (i)  A class of equity securities of the Issuer becoming eligible for
          termination of registration pursuant to Section 12(g)(4) of the
          Securities Exchange Act of 1934; or

     (j)  Any action similar to any of those enumerated above.

Item 5.  Interest in Securities of the Issuer

     (a)  Amount Beneficially Owned:

               Devma presently owns 533,095 shares of Common Stock and would
               acquire 177,700 additional shares of Common Stock upon exchange
               of all its common shares of CTEK if such exchange occurred as of
               the date hereof.

          Percent of Class:

               Based on 7,236,631 shares outstanding, being the number of shares
               of Common Stock represented by the Issuer to the Investors to be
               outstanding as of October 16, 1997 before the purchase of shares
               by the Investors (6,170,439) plus the Investors' shares of Common
               Stock issued on October 16, 1997 (1,066,192):

               Devma beneficially owns 9.6% of the outstanding Common Stock

         (b) Number of shares as to which Devma has:

               (i)  sole power to vote or direct the vote: 710,795 shares

               (ii) shared power to vote or direct the vote: 0 shares

              (iii) sole power to dispose or to direct the disposition of:
                    710,795 shares

               (iv) shared power to dispose or to direct the disposition of: 
                    0 shares
<PAGE>

         (c) Except as set forth in Item 3 herein, none of Devma, and to the
best knowledge of Devma, any person named in Schedule I has effected any
transaction in the Common Stock during the past 60 days.

         (d) Pursuant to an agreement between the Investors entered into on
October 17, 1997 (the "Investors' Agreement") more fully described hereinafter
in Item 6, notwithstanding the actual number of shares of Common Stock of the
Issuer and the actual number of common shares of CTEK owned by each Investor,
all dividends received by the Investors on their shares of Common Stock of the
Issuer and the common shares of CTEK shall be redistributed in the following
manner between the Investors: Devma shall receive 33.33% of such sums,

          (e) Not applicable

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to
        Securities of the Issuer.

         Pursuant to an agreement dated October 16, 1997 between the Issuer, the
Investors and Fred E. Klimpl and Jonas Medney, the Issuer agreed to use its best
efforts to nominate for election by its stockholders, cause the election of and
thereafter continue in office, one person designated by the Investors.
Furthermore, each of Fred E. Klimpl, a director of the Issuer and holder of
599,990 shares of the issued and outstanding shares of Common Stock and Jonas
Medney, a director of the Issuer and holder of 1,199,977 shares of the issued
and outstanding shares of Common Stock, has agreed, subject to certain
limitations and solely in his capacity as a shareholder of the Issuer, to vote
his shares of the capital stock of the Issuer in a manner so as to give effect
to the foregoing covenant of the Issuer. No agreement among the Investors has
been reached as to how to designate such director.

                  The Investors' Agreement states that, notwithstanding the
actual number of shares of Common Stock and common shares held by each Investor
in the capital of the Issuer and CTEK, respectively, when one Investor wishes to
exchange the common shares of CTEK for shares of Common Stock of the Issuer
pursuant to the Exchange Agreement discussed in Item 4, but one or more of the
other Investors does not wish to proceed with such exchange, a reallocation of
the shares of all Investors will be effected to reflect the following holdings:

Investor          Shares of Common Stock of Issuer       Class A shares of CTEK
- --------          --------------------------------       ----------------------
Devma                           355,398                             355,397
Innovatech                      355,398                             355,397
FSTQ                            319,858                             319,858
Fonds Regional                  35,539                               35,539

         The Investors have also agreed to redistribute their shareholding in
the Issuer and CTEK in the event of a forced liquidation or sale by an Investor
of shares of the Issuer or CTEK.

         For purposes of dividends, notwithstanding the actual number of shares
of Common Stock of the Issuer and the actual number of common shares of CTEK
owned by each Investor, all dividends received by the Investors on their shares
of Common Stock of the Issuer and the common shares of CTEK shall be
redistributed in the following manner between the Investors: Devma shall receive
33.33% of such sums, Innovatech shall receive 33.33% of such sums, FSTQ shall
receive 30% of such sums and Fonds Regional shall receive 3.33% of such sums.

<PAGE>
         However, the Investors' Agreement only governs shares of Common Stock
of the Issuer issued to the Investors on October 16, 1997 and common shares of
CTEK issued to the Investors on October 16, 1997 and does not govern any
additional shares acquired thereafter by any of the Investors.

          amount(s) from the aforesaid date until payment in full at a rate per
          annum equal to the Prime Rate, plus two (2) percentage points.
          Interest shall be calculated and payable monthly on the last day of
          each month during which any amount in respect of any Loss, and/or any

<PAGE>

                                      -34-

          payable in any month shall be calculated on the average amount of all
          amounts in respect of any Loss, and/or any Additional Indemnity if
          applicable, that remained unpaid at any time during such month. This
          amount shall be calculated by i) multiplying any amount in respect of
          each Loss that remained unpaid at any time during such month by the
          number of days that amount remained unpaid during such month and ii)
          dividing the aggregate of all such products by the number of days in
          such month. If such Claim is subsequently determined not to have been
          valid, the Indemnified Party shall reimburse the Indemnifying Party
          for the amount so paid together with interest at the Prime Rate per
          annum, plus two (2) percentage points, calculated and payable monthly
          as provided previously in this subsection, from the month such payment
          was made by the Indemnifying Party to the month in which the
          Indemnified Party repaid such amount.

     6.5. Additional Indemnity. If the Corporation is the Indemnifying Party, in
          addition to the reimbursement to the Indemnified Party of the amount
          of each Loss suffered or incurred by the Indemnified Party as provided
          in subsection 6.4 hereof, the Indemnifying Party shall pay, on demand,
          to the Indemnified Party the Additional Indemnity, the whole as
          provided in subsection 6.4 hereof. The Additional Indemnity shall be
          calculated in accordance with the following formula:

                                           (Infinity)      (n+1)
                                                        AI = (SIGMA) x y
                                                           n = 0

          where: AI = Additional Indemnity
                      x = Loss
                      y = Proportion

          Example: if Loss  = $200,000

AI = (200,000 X 15%) + (200,000 X 15% X 15%) + (200,000 X 15% X 15% X 15%) ...

AI = $30,000 + $4,500 + $675 + $101.25 + $15.19 + $2.28 + $0.34 + $0.05 + $0.008

The Additional Indemnity payable to the Indemnified Party is an amount of
$35,294.12

     6.6. Notification. Promptly upon obtaining knowledge thereof, the
          Indemnified Party shall notify the Indemnifying Party of each Claim
          which the Indemnified Party has determined has given or could give
          rise to indemnification under this Section 6, describing such Claim in
          reasonable detail. In circumstances where the Indemnifying Party is
          notified of such Claim but not promptly, the Indemnifying Party shall
          not be relieved from any duty to indemnify and save and hold harmless

<PAGE>

                                      -35-

          which otherwise might exist with respect to such Claim unless (and
          only to that extent) the omission to notify promptly materially
          prejudices the ability of the Indemnifying Party to exercise its right
          to defend provided in this Section 6.

     6.7. Defense of Third Party Claims. The Indemnifying Party shall have the
          right, after receipt of the Indemnified Party's notice under
          subsection 6.6 hereof with respect to a Third Party Claim and upon
          giving written notice to the Indemnified Party within ten (10)
          Business Days of such receipt, and subject to the rights of any
          insurer or other third party having potential liability therefor, to
          defend the Third Party Claim at its own cost and expense with counsel
          of its own selection, provided that:

          6.7.1.    the Indemnified Party shall at all times have the right to
                    fully participate in the defense at its own expense;

          6.7.2.    the Third Party Claim seeks only monetary damages and does
                    not seek any injunctive or other relief against the
                    Indemnified Party;

          6.7.3.    the Indemnifying Party unconditionally acknowledges in
                    writing its obligation to indemnify and save and hold the
                    Indemnified Party harmless with respect to the Third Party
                    Claim, if it is found that such obligation exists; and

          6.7.4.    legal counsel chosen by the Indemnifying Party is
                    satisfactory to the Indemnified Party, acting reasonably.

     6.8. Settlement of a Third Party Claim. The Indemnifying Party shall not be
          permitted to compromise and settle or to cause a compromise and
          settlement of any Third Party Claim, without the prior written consent
          of the Indemnified Party, unless:

          6.8.1.    the terms of the compromise and settlement require only the
                    payment of money and do not require the Indemnified Party to
                    admit any wrongdoing or take or refrain from taking any
                    action;

          6.8.2.    the Indemnifying Party delivers to the Indemnified Party a
                    letter of credit, surety bond or similar security in form
                    and substance satisfactory to the Indemnified Party, acting
                    reasonably, in the amount of such compromise and settlement
                    (including interest and costs, if any, payable pursuant
                    thereto) as security for the payment thereof;

          6.8.3.    the Indemnified Party receives, as part of the compromise
                    and settlement, a legally binding and enforceable
                    unconditional satisfaction and release, which is in form and
                    substance satisfactory to the Indemnified Party, acting
                    reasonably; and

<PAGE>

                                      -36-


          6.8.4.    the Third Party Claim and any claim or liability of the
                    Indemnified Party with respect to such Third Party Claim is
                    being fully satisfied because of the compromise and
                    settlement and the Indemnified Party is being released from
                    any and all obligations or liabilities it may have with
                    respect to the Third Party Claim.

     6.9. Waiver of Right to Defend Third Party Claims. If the Indemnifying
          Party fails:

          6.9.1.    within fifteen (15) Business Days from receipt of the notice
                    of a Third Party Claim to give notice of its intention to
                    defend the Third Party Claim in accordance with subsection
                    6.7 hereof, or

          6.9.2.    to comply at any time with any of subsections 6.7.1 through
                    6.7.4 (inclusively) hereof,

then the Indemnifying Party shall be deemed to have waived its right to defend
the Third Party Claim and the Indemnified Party shall have the right (but not
the obligation) to undertake the defense of the Third Party Claim and compromise
and settle the Third Party Claim on behalf, for the account and at the risk and
expense of the Indemnifying Party.

     6.10. Direct Claims. If the Indemnifying Party fails to respond in writing
          to any written notice of a Direct Claim given by the Indemnified Party
          pursuant to subsection 6.6 hereof, and fails to make an Indemnity
          Payment to the Indemnified Party within ten (10) Business Days
          thereof, the Indemnifying Party shall be deemed to have rejected such
          Direct Claim, in which event the Indemnified Party shall be free to
          pursue such rights, recourses and remedies as may be available to it.

     6.11. De Minimis, Deductible and Maximum Payment. Notwithstanding anything
          contained herein:

          6.11.1.   the Investors shall not be entitled to indemnification
                    arising under subsection 6.2.2 hereof unless the aggregate
                    of all amounts payable by the Corporation in connection with
                    its indemnification obligations thereunder exceeds ten
                    thousand dollars ($10,000);

          6.11.2.   the Corporation shall not be entitled to indemnification
                    arising under subsection 6.3.2 hereof unless the aggregate
                    of all amounts payable by the Investors in connection with
                    their indemnification obligations thereunder exceeds ten
                    thousand dollars ($10,000);

          6.11.3.   the amounts payable by the Indemnifying Parties to the
                    Indemnified Parties in connection with their indemnification
                    obligations pursuant to subsection 6.2.2 or 6.3.2, as the
                    case may be, are subject to a cumulative deductible of one
                    hundred thousand dollars ($100,000). For purposes of clarity
                    and


<PAGE>

                                      -37-

                    without limiting the foregoing, the Indemnified Parties
                    shall not be entitled to any payment unless the aggregate of
                    all the amounts which should have been paid by the
                    Indemnifying Parties to the Indemnified Parties in
                    connection with their indemnification obligations pursuant
                    to subsection 6.2.2 or 6.3.2, as the case may be, is greater
                    than one hundred thousand dollars ($100,000);

          6.11.4.   the aggregate amount payable by the Corporation to an
                    Investor in connection with the indemnification obligations
                    pursuant to subsection 6.2. shall be limited to the
                    aggregate of the following amounts (the "Maximum
                    Indemnification Amount") (i) the aggregate subscription
                    price paid by such Investor for all of its Common Shares
                    pursuant to this Agreement; (ii) the aggregate subscription
                    price paid by such Investor for all of its shares in the

                    by such Investor for all shares in the capital stock of
                    Compositech Canada purchased from the Corporation; (v) the
                    aggregate amount loaned to Compositech Canada by such
                    Investor; (vi) the aggregate amount paid by such Investor in
                    connection with any guarantees furnished by it on behalf of

                    incurred by such Investor in connection with the matters
                    described in items (i) through (vi) above. In the event of a
                    transfer by any Investor to (a) another Investor, (b) a
                    Permitted Transferee (as defined in the Compositech Canada
                    Shareholders Agreement) of such Investor, (c) a Governmental
                    Body of or controlled by the Government of Quebec or (d) a
                    limited partnership controlled by such Investor or by any
                    Governmental Body of or controlled by the Government of
                    Quebec or of which such Investor or any Governmental Body of
                    or controlled by the Government of Quebec holds the majority
                    of the limited partnership units, of any of the shares
                    contemplated in items (i) through (iv) above and/or any of
                    the indebtedness contemplated in items (v) and (vi) above,
                    the Maximum Indemnification Amount in connection with such
                    transferee shall be increased by the portion of the selling
                    Investor's Maximum Indemnification Amount corresponding to
                    the transferred shares and/or indebtedness and the Maximum
                    Indemnification Amount of such selling Investor shall be
                    reduced accordingly.

          hereafter acquire under Applicable Law, and any right, recourse or
          remedy of such Indemnified Party may be asserted completely against
          the Indemnifying Party, without regard to the rights, recourses or
          remedies the Indemnified Party may have against any other Person.

          the representations and warranties made by it in this Agreement apply
          in favour of the Investors as if made in the Subscription Agreement in

          notified of such Claim but not promptly, the Indemnifying Party shall

          which otherwise might exist with respect to such Claim unless (and

          right, after receipt of the Indemnified Party's notice under

          Business Days of such receipt, and subject to the rights of any
          insurer or other third party having potential liability therefor, to
          defend the 



<PAGE>
                                      -12-


          Third Party Claim at its own cost and expense with counsel of its own
          selection, provided that:

          6.6.1.    the Indemnified Party shall at all times have the right to
                    fully participate in the defense at its own expense;

          6.6.2.    the Third Party Claim seeks only monetary damages and does
                    not seek any injunctive or other relief against the
                    Indemnified Party;

          6.6.3.    the Indemnifying Party unconditionally acknowledges in
                    writing its obligation to indemnify and save and hold the
                    Indemnified Party harmless with respect to the Third Party
                    Claim, if it is found that such obligation exists;

          6.6.4.    legal counsel chosen by the Indemnifying Party is
                    satisfactory to the Indemnified Party, acting reasonably;
                    and

          6.6.5.    the Indemnifying Party delivers a letter of credit, surety
                    bond or similar security in form and substance satisfactory
                    to the Indemnified Party, acting reasonably, in an amount
                    which the Indemnified Party, acting reasonably, determines
                    is sufficient to cover such Third Party Claim as security
                    for the payment of amounts payable by the Indemnifying Party
                    to the Indemnified Party pursuant hereto, inclusive of
                    reasonably estimated interest and costs. Amounts payable by
                    the Indemnifying Party pursuant to a Third Party Claim shall
                    be paid in accordance with the terms of the settlement or
                    judgment, as applicable, but in any event prior to the
                    expiry of any delay for a judgment to become executory.

     6.7. Waiver of Right to Defend Third Party Claims. If the Indemnifying
          Party fails:

          6.7.1.    within fifteen (15) Business Days from receipt of the notice
                    of a Third Party Claim to give notice of its intention to
                    defend the Third Party Claim in accordance with subsection
                    6.6 hereof, or

          6.7.2.    to comply at any time with any of subsections 6.6.1 through
                    6.6.5 (inclusively) hereof,

then the Indemnifying Party shall be deemed to have waived its right to defend
the Third Party Claim and the Indemnified Party shall have the right (but not
the obligation) to undertake the defense of the Third Party Claim and compromise
and settle the Third Party Claim on behalf, for the account and at the risk and
expense of the Indemnifying Party.

     6.8. Direct Claims. If the Indemnifying Party fails to respond in writing
          to any written notice of a Direct Claim given by the Indemnified Party
          pursuant to subsection 6.5 hereof, and fails to make an Indemnity
          Payment to the Indemnified Party within ten 


<PAGE>
                                      -13-


          (10) Business Days thereof, the Indemnifying Party shall be deemed to
          have rejected such Direct Claim, in which event the Indemnified Party
          shall be free to pursue such rights, recourses and remedies as may be
          available to it.

     6.9. Right of Offset. Without in any way limiting the terms of this Section
          6, each party shall have the right to offset against all amounts
          payable from time to time by it to the other party, howsoever arising,

AUTHORIZATION AND EXCHANGE OF CANCO SHARES

          Authorization. Prior to the date hereof, the Company has authorized
               the exchange and issuance, in accordance with the terms hereof,
               of up to one million two hundred thousand (1,200,000) Common
               Shares.

          Voluntary Exchange of Canco Shares. Subject to the terms and
               conditions hereof, each Purchaser shall have the right to
               exchange, at any time and from time to time, all or part of its
               Canco Shares for Common Shares at the Exchange Rate (the
               "Exchange Right").

          Forced Exchange of Canco Shares. Subject to the terms and conditions
               hereof, the Company shall have the right to require all (and not
               less than all) of the Purchasers to exchange all (and not less
               than all) of their Canco Shares for Common Shares at the Exchange
               Rate (the "Forced Exchange"), it being understood that this right
               may only be exercised by the Company for all of the Canco Shares
               held by all the Purchasers.

          Exchange Rate. Subject to subsections 3.5 and 3.7, the Company shall
               issue to each Purchaser upon delivery by such Purchaser of (i)
               each Initial Canco Share, one (1) Common Share; (ii) each Project
               Canco Share, that number of Common Shares as is equal to the
               quotient obtained when dividing the Total Project Common Shares
               of such Purchaser by the Total Project Canco Shares of such
               Purchaser; (iii) each Distress Canco Share, that number of Common
               Shares as is equal to the quotient obtained when dividing the
               Total Distress Common Shares of such Purchaser by the Total
               Distress Canco Shares of such Purchaser; and (iv) each Subsequent
               Canco Share, that number of Common Shares as is equal to the
               quotient obtained when dividing the Total Subsequent Common
               Shares of such Purchaser by the Total Subsequent Canco Shares of
               such Purchaser. In the event that Project Canco Shares, Distress
               Canco Shares or Subsequent Canco Shares are issued on more than
               one occasion, the Exchange Rate will be determined separately at
               the time of each issuance and, as a consequence, the Exchange
               Rate may not be the same for all Project Canco Shares, all
               Distress Canco Shares or all Subsequent Canco Shares.

          Adjustment to the Number of Common Shares. The number of Common Shares
               to be issued upon the exchange referred to in subsection 3.2 or
               3.3 shall be adjusted to take into account changes to and
               dilutive events in respect of the Common Shares occurring during
               the period from the Adjustment Commencement Date until the date
               of such exchange. Such adjustment shall be made such that the
               Purchasers shall be issued such number of Common Shares (or any
               security or other property or rights such Common Shares may have
               become) as shall be equal to the number 


<PAGE>
                                      -9-


               of Common Shares (or such security or other property or rights
               which the Common Shares may have become) the Purchasers would
               have been issued in the aggregate if they had exercised the
               Exchange Right or if the Company had exercised the Forced
               Exchange upon the Adjustment Commencement Date and the Purchasers
               had owned such shares from the Adjustment Commencement Date until
               the date of the exchange. For greater clarity, but without
               limiting the generality of the foregoing, if the Company shall
               undertake a Share Reorganization, Capital Reorganization or
               Special Distribution (collectively, a "Recapitalization") prior
               to the issuance of the Common Shares to the Purchasers upon the
               exchange referred to in subsection 3.2 or 3.3, each Purchaser
               shall receive upon the exchange referred to in subsection 3.2 or
               3.3 such number of Common Shares or securities or other property
               or rights as such Purchaser would have received following such
               Recapitalization had such Purchaser been issued its Common Shares
               pursuant to any exchange prior to such Recapitalization and had
               subsequently participated fully in such Recapitalization. The
               adjustments provided for herein are cumulative and such
               adjustments shall be made successively whenever an event referred
               to in this subsection 3.5 occurs.

          Officer's Statement. Whenever the Exchange Rate is adjusted as
               provided in subsection 3.5, the Company shall forthwith send to
               each Purchaser a statement, signed by an officer of the Company,
               describing in reasonable detail the facts giving rise to such
               adjustment, as well as the new Exchange Rate. This statement
               shall be accompanied by a letter from the auditors of the Company
               confirming the new Exchange Rate. If a dispute arises with
               respect to any adjustment in the Exchange Rate, such dispute
               shall be settled by arbitration in the manner provided in
               subsection 8.4 hereof.

          Fractional Shares. No fractional Common Shares shall be issued upon
               the exchange of the Canco Shares pursuant to subsection 3.2 or
               3.3. In lieu of issuing any fractional Common Shares to any
               Purchaser upon such exchange, the Company shall pay to such
               Purchaser a cash adjustment in respect thereof in an amount equal
               to the product obtained when multiplying the Average Closing
               Price Per Common Share calculated on the date of the exchange by
               the fraction of the Common Share which would otherwise have been
               issued.

EXCHANGE RIGHT

          Voluntary Closing. Each closing of the exchange of the Canco Shares
               for Common Shares pursuant to subsection 3.2 (the "Voluntary
               Closing") shall be held at the offices of the Company in
               Hauppauge, New York, at 10:00 a.m., local time, fifteen (15)

          Delivery. At each Voluntary Closing, each Purchaser who has given a
               Notice of Exchange shall surrender the certificate or
               certificates for the Canco Shares contemplated therein duly
               endorsed. Thereupon, the Company shall issue and deliver at such
               office to such Purchaser a certificate or certificates for the
               number of Common Shares to which such Purchaser is entitled
               pursuant to subsection 3.4. Such exchange shall be deemed to have
               been made at the close of business on the date of receipt by the
               Company of the Notice of Exchange and the Purchaser entitled to
               receive Common Shares issuable upon such exchange shall be
               treated for all purposes as the record-holder of such Common
               Shares on the date of receipt by the Company of the Notice of
               Exchange.

          Conditions Precedent to Voluntary Closing. The obligation of each
               Purchaser to proceed with each Voluntary Closing is subject to

                    behalf of Canco and Canco shall have repaid to such
                    Purchaser all amounts loaned by such Purchaser to Canco,

                    such Purchaser; and

               if a demand registration in accordance with subsection 4.1 of

               effective must be in writing:

               the representations and warranties of the Company contained in

                    counsel to the Company acceptable to such Purchasers,
                    covering substantially the same matters as were covered in
                    the opinion furnished by such counsel to the Purchasers on
                    the date hereof;

               the Company shall have furnished to the Purchasers an officer's

               the Company shall have delivered to the Purchasers all consents
                    and approvals of all Persons required in order to consummate
                    the transactions contemplated by the Forced Exchange, each
                    Purchaser's Sale Notice and this Section 5. In addition, and
                    without limiting the generality of the foregoing, the
                    Entente Canada-Quebec Consents and the consent of any lender
                    of Canco shall have been delivered to the Purchasers; and

               if a demand registration in accordance with subsection 4.1 of
                    the Registration Rights Agreement is requested by such
                    Purchaser within five (5) Business Days following receipt of
                    the Forced Exchange Notice, the Company shall have filed all
                    appropriate registration statements or resale registration
                    statements required by the Registration Rights Agreement in
                    connection with the Common Shares to be issued upon the
                    Forced Exchange and same shall have been declared effective.

     Failure to Satisfy Conditions Precedent to Forced Closing. In the event
          that any of the conditions precedent set forth in subsections 5.5
          hereof shall not have been fulfilled and/or performed as of the
          Closing Date, each of the Purchasers may, at its option, either (i)
          advise the Company that it refuses to proceed with the exchange of its
          Canco Shares or (ii) proceed with the exchange of its Canco Shares, in
          either case, without prejudice to its rights, recourses and remedies.
          In the event, however, that one or more but less than all of the
          Purchasers exercises the option set forth in (i) above, then the
          Company shall have the right not to proceed with the Closing of the
          Forced Exchange of the Canco Shares held by the other Purchasers who
          wished to proceed therewith, in which case such other Purchasers shall
          be deemed to have exercised the option set forth in (i) above.

     Failure to Satisfy Certain Condition Precedent to Forced Closing.
          Notwithstanding the first sentence of subsection 5.6, in the event
          that the only condition precedent not to have been fulfilled and/or
          performed as of the Closing Date is the condition precedent set forth
          in paragraph 5.5.9, then each of the Purchasers may, at its option,
          either (i) proceed with the exchange of its Canco Shares, without
          prejudice to its rights, recourses and remedies; or (ii) postpone the
          Closing Date until this condition precedent is fulfilled and/or
          performed, provided that if same is not fulfilled and/or performed
          within 90 days of the original Closing Date, then each of the
          Purchasers shall be entitled to exercise either of the options set
          forth in the first sentence of subsection 5.6. In the event, however,
          that one or more but less than all of the Purchasers exercises the
          option set forth in (i) above, then the Company shall have the right
          not to proceed with the Closing of the Forced Exchange of the Canco
          Shares held by the other Purchasers who wish to proceed therewith, in
          which case such other Purchasers shall be deemed to have exercised the
          option set forth in (ii) above.

     Delivery. At the Forced Closing, the Purchasers shall surrender the
          certificates representing all of the Canco Shares, duly endorsed.
          Thereupon, the Company 


<PAGE>

          shall issue and deliver to the Purchasers certificates for the number
          of Common Shares to which the Purchasers are entitled pursuant to
          subsection 3.4. Such exchange shall be deemed to have been made at the
          close of business on the date of receipt by the Purchasers of the
          Forced Exchange Notice and the Purchasers shall be treated for all
          purposes as the record-holders of such Common Shares on the date of
          receipt by the Purchasers of the Forced Exchange Notice. In addition,
          in the event that any Purchaser has provided the Company with its
          Purchaser's Sale Notice, such Purchaser shall also surrender the
          certificates representing all of the Common Shares which it wishes to
          sell, duly endorsed, against payment of the purchase price therefor.

          follows:

          Investment. In each case, it is acquiring the right to acquire, and
               will acquire, Common Shares as provided in this Agreement, as

               investment for its own account (or for the account of any of the
               other Purchasers), and not with the view to, or for resale in

               have upon each Closing Date good and marketable title to the
               Canco Shares and the absolute right, power and capacity to
               transfer and deliver the Canco Shares to the Company pursuant to

     Acknowledgements. Each Purchaser hereby makes the following
          acknowledgements:

               Securities Act or under any applicable U.S. state securities
               laws, in reliance on specific exemptions from the registration
               provisions of the Securities Act and such laws, the availability
               of which depends upon, among other things, the bona fide nature
               of its investment intent and the accuracy of the other
               representations and acknowledgments set forth in this Section
               7.1.1.

               registered and/or qualified under the Securities Act and
               applicable U.S. state securities laws or, in the opinion of
               Purchaser's counsel reasonably satisfactory to the Company,
               exempt from such registration and/or qualification.

          Accredited Investor. It is an "accredited investor" within the meaning
               of Rule 501 under the Securities Act.

          Legends. It understands that the certificates representing Common
               Shares will bear a legend containing the restrictions referred to
               in paragraphs 7.1.1 and 7.1.2 above.

that (i) the Investors' Nominee shall have experience commensurate with serving
as a director of the Corporation, and (ii) the Investors' Nominee shall not at
the time of designation or at any time thereafter be, or have been, involved in
any legal proceedings which would be required to be disclosed pursuant to Item
401(f) of Regulation S-K (17 C.F.R. ss.229) in a filing with the United States
Securities and Exchange Commission. Subject to the terms of this Agreement, the
Corporation shall continue to include in the Board of Directors slate of
nominees for election as a director of the Corporation at its annual meeting of
stockholders, any special meeting of stockholders or by consent of stockholders

each of the Principal Shareholders, each of the Principal Shareholders hereby
covenants and agrees solely in his capacity as a shareholder of the Corporation
to vote his shares of the capital stock of the Corporation in a manner so as to
give effect to the foregoing paragraph. In the event, however, that an

reasonably, without regard to whether to proviso of the foregoing paragraph has
been satisfied, the Principal Shareholders shall advise the Investors of same in
writing within 48 hours of being provided with such information generally
required in regard to a director of a corporation pursuant to Item 401 of
Regulation S-K in respect to the proposed Investors' Nominee, whereupon the
Investors shall designate another person if they wish the Principal Shareholders
to vote in favor of the Investors' Nominee. The right provided to the Principal
Shareholders in the preceding sentence may be exercised only once with respect
to each meeting or consent pursuant to which the Corporation's stockholders are
being asked to vote for nominees to the Board of Directors of the Corporation;
thereafter, in the case of any such meeting or consent where such right has been
exercised, the Principal Shareholder shall not be entitled to refuse the next
proposed Investors' Nominee in accordance with the above sentence.

     As further conditions of the Corporation's and the Principal Shareholders'
obligations under this Agreement, (i) the Investors shall cooperate in and bear
the entire cost (including the reasonable legal expenses of the Corporation
and/or the Principal Shareholders) of providing in a timely manner all
information that is required to be disclosed in, and, to the extent required by
law, shall cause to have prepared and filed, a Statement on Schedule 13D under

severally agrees to indemnify and hold harmless, to the extent permitted by law,
each of the Principal Shareholders from and against any and all liabilities,
losses, damages, settlements, claims, costs or expenses, including, without
limitation, reasonable attorneys' fees (collectively, "Liabilities") under U.S.
Federal, state or local laws arising out of or due to (A) any untrue statement
or alleged untrue statement of a material fact by such Investor contained in the
Schedule 13D of (B) any omission or alleged omission by such Investor to state
in the Schedule 13D a material fact required to be stated therein or necessary
to make the statements therein, in light of the circumstances under which they
were made, not misleading. As consideration for the Principal Shareholders
entering into this agreement, the Corporation agrees to indemnify and hold
harmless, to the extent permitted by law, each Principal Shareholder from and
against all Liabilities under U.S. Federal, state or local laws arising out of
or due to the Principal Shareholder's compliance with the terms of this
Agreement. Such agreement by the Corporation to indemnify shall survive any
cancellation or termination, or the invalidity or unenforceability of, the
remaining terms hereof.

     This Agreement shall terminate on the date on which the Investors own less
than the number of shares of Common Stock of the Corporation in the aggregate as
is specified in Section 7.2 of the Subscription Agreement of even date herewith

adjusted in accordance with the terms of Section 7.2 of the Subscription
Agreement.

Corporation's directors or officers, acting individually or collectively, from
taking any action required for such directors or officers to discharge their
fiduciary duties to the Corporation and its shareholders. All notices and other
communications hereunder shall be given in writing and shall be given by
telecopier, or delivered by hand, to the other parties at their respective

the Government of Quebec; or (iii) a limited partnership controlled by an
Investor or by any governmental body of or controlled by the Government of

     2.   The terms and conditions of the Compositech Canada and Compositech US

          the Compositech Canada shareholders agreement and the exchange
          agreement. The present Agreement shall be read together with the

          ----------------------------------------------------------------------
          Innovatech                         $3,749,992.96562       533,095

          ======================================================================

     4.   The issue price per share for the shares of Compositech US and
          Compositech Canada was set at $7.03438. The shares of both Compositech
          US and of Compositech Canada, were issued at an identical issue price
          in order to facilitate the eventual exchange of shares on a share per
          share basis at the time such exchange is effected pursuant to the
          exchange agreement entered into between the Investors and Compositech
          US or the reallocation of shares of Compositech Canada or Compositech
          US among the Investors.

          The present Agreement exclusively contemplates the 710,792 shares held
          by Fonds and Fonds regional in the capital of Compositech Canada and
          the 533,095 shares held by Devma and the 533,095 shares held by
          Innovatech in the capital of Compositech US.

          For the purposes herein, Fonds and Fonds regional hereby represent to
          the other Investors that they are acting together through Fonds. Fonds
          regional represents that it has granted to Fonds a proxy for the
          purpose of all matters related to Compositech Canada and/or
          Compositech US and in particular all matters relating to the present
          Agreement.

     5.   Notwithstanding the allocation set forth in paragraph 3 and
          independent of the allocation of the capital and the number of shares
          held by each Investor in the capital of Compositech US and Compositech
          Canada, the objective of the Investors is to have, at a given time, an
          equal position with respect to shares in Compositech US and
          Compositech Canada, Fonds and Fonds regional to be considered
          together. Moreover, independent of the actual allocation, each
          Investor (Fonds regional with/and through Fonds) shall have identical
          rights from the date hereof regarding voting, dividends and other
          privileges attached to the shares of Compositech Canada and regarding
          dividends and other privileges attached to the shares of Compositech
          US.

     6.   Dividends

          Any dividend on the shares of the capital of Compositech Canada or
          Compositech US shall be redistributed in equal parts among the
          Investors. Where the Investors receive a direct payment of dividends,
          each undertakes to proceed with a reallocation of the 


<PAGE>
                                      -4-


          amounts received into equal parts among the Investors and as a result
          shall proceed to a redistribution of such amounts. The Investors
          undertake to distribute the shares among them immediately prior to the
          declaration or payment of a dividend, in order to avoid any
          unfavourable tax consequences against one or the other of the
          Investors.

     7.   Vote

          With respect to Compositech Canada, the Investors agree that the
          Compositech Canada shareholders agreement will at all times provide
          for a proportional representation of Investors on the board of
          directors of Compositech Canada. Given that the Investors are holders
          of an equal number of shares and given their intention to maintain
          such participation in equal numbers, each shall designate a
          representative to the board of directors provided that the Investors
          are entitled to designate three (3) representatives. This principle
          shall be modified where one or more of the Investors proceed to
          additional investments by way of share purchases, which alters their
          respective shareholdings. In such a case, the designation of the
          representatives, whether it is for three (3), four (4) or more
          representatives pursuant to the provisions in the Compositech Canada
          shareholders agreement, shall be made on a proportional basis based on
          the number of shares held by each of the Investors. Where the
          Investors have proceeded together to additional investments on a pro
          rata basis to their respective participation by way of share
          purchases, the designation of additional representatives (more than 3)
          shall be made by way of a common agreement among the Investors to have
          an equitable representation among the Investors and where appropriate,
          provide the opportunity to each Investor to designate an additional
          representative to the board of directors of Compositech Canada. For
          the purposes hereof, "held" means the shares deemed to be held by each
          Investor in equal parts plus the shares actually acquired thereafter
          and held by one or more of the Investors. In addition, where at any
          time the three (3) Investors have the right to designate less than
          three (3) representatives to the board of directors of Compositech
          Canada, the parties shall appoint their representatives by way of
          mutual agreement or in a proportional manner as provided for
          hereinabove. With respect to the board of directors and shareholders
          meetings of Compositech Canada, the Investors agree to vote as
          shareholders and to mandate their representative to vote as a director
          in accordance with the decision taken by the majority (51% of the
          voting shares held by the Investors). The Investors shall consult with
          each other before taking any decision.

          Notwithstanding the rules provided for hereinabove, the provisions of
          section 6 of the shareholders agreement with respect to Compositech
          Canada shall have priority and precedence over the provisions of the
          present paragraph.

     8.   Conversion or exchange at the discretion of the Investors

          The shares held by the Investors in the capital of Compositech Canada
          confer a right to exchange such shares for shares in the capital of
          Compositech US, the whole as provided 



<PAGE>
                                      -5-


          for in the exchange agreement. Within three (3) years following
          execution of the Compositech Canada shareholders agreement, where an
          Investor wishes to proceed to an exchange of shares that it holds in
          the capital of Compositech Canada for shares in the capital of
          Compositech US, it shall provide written notice to this effect to the
          two (2) other Investors and shall not so proceed until all the
          Investors have proceeded together to the exchange of their shares or
          have mutually agreed to some other mechanism. In such a case or at any
          time, commencing from the third (3rd) year following the execution of
          the Compositech Canada shareholders agreement, where an Investor
          wishes to proceed to an exchange of shares that it holds in the
          capital of Compositech Canada for shares in the capital of Compositech
          US, the provisions provided for hereinafter shall apply.

          Upon an Investor giving notice to the others of its intention to
          exchange shares and therefore to redistribute the shares in order that
          each Investor holds an equal number of shares in the capital of
          Compositech Canada and in the capital of Compositech US, the following
          provisions shall apply:

          8.1  where each Investor is prepared to proceed with an exchange for
               shares in Compositech US, each Investor shall exchange its shares
               in the capital of Compositech Canada for shares in the capital of
               Compositech US according to the provisions of the exchange
               agreement. Consequently, with respect to the shares contemplated
               by the initial subscription, the three Investors shall hold an
               equal number of shares in the capital of Compositech US without
               executing any transaction among them.

          8.2  where one or more Investors do not wish to proceed to the
               exchange, the Investors shall proceed to an allocation among them
               whereby Fonds shall sell 177,697 shares in the capital of
               Compositech Canada to Devma and 177,698 shares in the capital of
               Compositech Canada to Innovatech for a price of $7.03438 per
               share. Simultaneously, Fonds shall purchase 177,697 shares in the
               capital of Compositech US from Devma and 177,698 shares in the
               capital of Compositech US from Innovatech at a price of $7.03438
               per share.

     The parties agree that with respect to the redistribution of shares among
     them pursuant to any transaction contemplated herein, the value of the
     issued shares in the capital of Compositech Canada shall be $7.03438 per
     share and the value of each issued share in the capital of Compositech US
     and held by Devma and Innovatech shall be equal to $7.03438 per share,
     notwithstanding the fair market value of said shares at the date of such
     transaction.

     In addition, the right for an Investor to proceed to an exchange of its
     shares shall be subject to the right of first refusal agreed upon by each
     for the benefit of the other Investors and provided for in the Compositech
     Canada shareholders agreement.


<PAGE>
                                      -6-


     The parties also undertake to proceed to a redistribution and reallocation
     of shares held in the capital of Compositech Canada and Compositech US
     pursuant to any provision provided for in the Compositech Canada
     shareholders agreement with respect to the sale, alienation or disposition
     of shares and in particular, the provisions provided for in sections 15 and
     20 of the shareholders agreement.

9.   Exchange at the discretion of Compositech US

     Where Compositech US exercises its right provided for in the exchange
     agreement to require the exchange by the Investors of their shares in the
     capital of Compositech Canada for shares in the capital of Compositech US,
     the Investors shall proceed to the exchange of shares in the capital of
     Compositech Canada for shares in the capital of Compositech US, the whole,
     according to the provisions provided for in the exchange agreement which
     bind the Investors to Compositech US and to the rules provided for in
     paragraph 0 hereinabove.

10.  Miscellaneous provisions

     With respect to dividends or other dispositions of assets, if any, any
     adjustments, where required, shall be made one (1) time per year, on the
     anniversary date of the execution of the present Agreement, unless an
     adjustment becomes necessary during the year, and in particular, any
     adjustment necessary for the reallocation of shares among the Investors to
     give effect to the present Agreement.

11.  Purchase of additional shares

     The present Agreement governs exclusively the holding and reallocation of
     shares issued upon the closing of the Compositech Canada and Compositech US
     transaction (initial subscription). Any acquisition of additional shares by
     one or more of the Investors shall be governed by the Compositech Canada
     shareholders agreement, subject to the exercise of the voting right
     provided for in paragraph 0 herein.

12.  Taxation

     Where a transaction is completed among the Investors pursuant to the
     present Agreement and any taxes are payable (sale or disposition of shares)
     and where Devma and/or Innovatech would not otherwise be taxed had the
     Fonds held the number of shares it should have held in the capital stock of
     Compositech US, Fonds undertakes and agrees to assume the entire tax
     liability owed by Devma and/or Innovatech and to indemnify and pay any
     claim for taxes that may become exigible.


<PAGE>
                                      -7-


     Notwithstanding the provisions of the preceding paragraph, Devma and
     Innovatech represent that they are not liable for tax in Canada nor in the
     United States on capital gains nor on dividends received from a Canadian or
     American corporation except for certain deductions at source for dividends
     paid by an American corporation to Canadian Investors. No unfavourable
     consequence shall be suffered or incurred by Devma or Innovatech by way of
     holding shares in the capital of Compositech US as provided for in the
     present Agreement. Each of Devma and Innovatech shall use its best efforts
     to inform Fonds in the shortest delays of any change in its tax status, if
     any, and in order to proceed to the redistribution of shares prior to the
     coming into force of any such change.

     For the purposes of any transaction, Devma and Innovatech shall be deemed
     to have held their shares in the capital of Compositech Canada commencing
     from the date of execution of the Compositech Canada subscription agreement
     and, if applicable, any tax implication created by the fact that Fonds
     holds securities which shall be eventually assigned and transferred to
     Devma and Innovatech shall be assumed entirely by Fonds and adjustments
     shall be made with Innovatech and Devma where necessary.

     Each of Devma and Innovatech agrees and accepts to amend the mechanism of
     redistribution of shares held in the capital of Compositech Canada and
     Compositech US in the event that a mechanism for redistributing shares held
     in the capital of Compositech Canada and Compositech US becomes more tax
     advantageous for Fonds without creating any costs or additional tax
     liability for Devma and/or Innovatech.

13.  Arbitration

     Any dispute or litigation that may arise in connection with the present
     Agreement shall be finally settled according to the rules of conciliation
     and arbitration of the Quebec Centre for National and International
     Commercial Arbitration annexed hereto as Schedule 1, at the date hereof by
     one or more arbitrators appointed in conformity with such rules and without
     recourse to any court proceedings. Any arbitration procedure required
     pursuant to the present shall be held at Montreal, Province of Quebec.

14.  Final provisions

     14.1 Any notice, request or communication required or permitted pursuant to
          the present Agreement, shall be made in writing and transmitted either
          by bailiff, prepaid registered mail, receipt return requested, or
          shall be hand delivered to the parties herein at the addresses
          indicated at the beginning of the present Agreement or any other
          address that one or the other parties may indicate to the other
          parties in the manner provided for herein. Any such notice shall be
          deemed to have been received on the day of service in the case of
          service by bailiff, on the 5th day following the date of mailing if
          sent by mail and the day of its delivery, if delivered by hand.

          cannot be modified or amended except by instrument in writing signed
          by all the parties hereto.

     14.3 All copies of the present Agreement, upon signature by each of the
          parties, shall constitute an original. The parties elect the domicile

          present Agreement.

     14.4 The parties undertake, within the limits of their undertakings
          contained herein, to sign any document, to ensure the holding of all
