              (ii)   the Final Company Transaction Expenses are less than the
                     Company Transaction Expenses deducted from the Purchase
                     Price as contemplated by Section 2.2,

              the Purchaser shall pay such difference or differences to the

              (ii)   the Final Working Capital Payment is less than the Working
                     Capital Payment paid by the Purchaser at the Closing,

              the Purchaser may claim such difference or differences from the
              Escrow Fund and any such claim shall not be subject to the
              limitations of Section 10.6 or the procedures required by Section
              10.2.

       (d)    Subject to Section 2.7(e), any payment or claim contemplated in
              Sections 2.7(b) and 2.7(c) shall be made by the Purchaser within

              to the Vendors.

       (e)    If the Vendors have any objections to the calculations contained
              in the Statement of Adjustments, the Vendors' Agent may, within
              fifteen (15) Business Days following delivery of the Statement of
              Adjustments, provide to the Purchaser a notice of objection (the
              "Notice of Objection") containing a statement on the basis of each
              of the Vendors' objections and each amount in dispute. If the
              Purchaser disputes the objections contained in the Notice of
              Objection, the parties shall work expeditiously and in good faith
              in an attempt to resolve such dispute within a further twenty (20)

              the final amount of the payment or payments as contemplated in
              this Section 2.7 shall be determined within forty (40) Business
              Days by a nationally-recognized Canadian firm of chartered
              accountants as may be agreed to by the parties and such
              determination shall be conclusive, final and binding on the
              Vendors and the Purchaser. The Vendors and the Purchaser shall
              share equally in all fees and expenses charged by such accountants
              for resolving such matter. The party required to make payment to
              the other party as determined by the accountants shall pay such
              amount within five (5) Business Days of such determination.

              provided to the Purchaser.

       (f)    Except as set forth in Section 6.21 of the Disclosure Schedule,
              there are no outstanding options, licenses, or agreements of the
              Company or any of its Subsidiaries of any kind relating to the
              provision of the Proprietary Software, the Company Products or the
              Company's Intellectual Property other than licenses to use or
              distribute granted by or to the Company in the ordinary course of
              business consistent with past practice, nor is the Company bound
              by or a party to any options, licenses or agreements of any kind
              with respect to the Intellectual Property of any other person
              other than licenses for Licensed Software and other licenses for
              software or other Intellectual Property used by the Company in the
              ordinary course of business. Neither the Company nor any of its
              Subsidiaries have granted (other than licenses of source code
              relating to the Olectra, JClass or XRT products to customers in
              the ordinary course of business) (i) a development license in
              relation to its Proprietary Software or in relation to its
              Intellectual Property, or (ii) any right (including an escrow
              agreement) capable of being converted into a development license
              in relation to its Proprietary Software or in relation to its
              Intellectual Property, nor has any one of them otherwise
              disclosed, licensed, transferred or released the source code of
              any of its Proprietary Software to any person other than
              disclosures to those of its employees and contractors involved in
              the development, modification or support of the Proprietary
              Software.

       (g)    To the knowledge of the Company and the Vendors, no person has
              interfered with, infringed upon or misappropriated any rights of
              the Company or its Subsidiaries with respect to the Software or
              the Company's Intellectual Property or illegally exported the
              Software.

              (i)    no current or former employees, consultants, contractors or
                     agents of the Company or any of its Subsidiaries have
                     misappropriated any Intellectual Property of any other
                     person in the course of the performance of their duties as
                     employees, consultants, contractors or agents of the
                     Company or its Subsidiaries;

              (ii)   none of the employees of the Company or any of its
                     Subsidiaries is obligated under any fiduciary duty or any
                     contract (including licenses, covenants or commitments of
                     any nature) or other agreement, or subject to any judgment,
                     decree or order of any court or Governmental Authority,
                     that interferes with such employee carrying out his or her
                     duties to the Company and its Subsidiaries or that
                     conflicts with the Company Business as now conducted; and

              (iii)  neither the execution and delivery of this Agreement, nor
                     the consummation of the transactions contemplated
                     hereunder, nor the carrying on of the Company Business by
                     the employees of the Company and of its Subsidiaries, nor
                     the conduct of the Company Business as now conducted, will
                     conflict with or result in a breach of the terms,
                     conditions or provisions of, or constitute a default under,
                     or a violation of any fiduciary duty or any contract,
                     covenant or instrument under which any of such employees is
                     now obligated.

       (i)    It is not and will not be necessary to utilize any Intellectual
              Property owned by any of the current or former employees of the
              Company or any of its Subsidiaries prior to their employment by
              the Company or its Subsidiaries (which has not since such hiring
              been purchased by the Company or its Subsidiaries), and none of
              the Vendors has any right, title or interest, individually or
              jointly with the Company or any other party, in or to any of the
              Software or the Company's Intellectual Property.

       (j)    The Intellectual Property owned by or, to the knowledge of the
              Company and the Vendors, licensed to the Company is subsisting,
              valid and enforceable and has not been adjudged invalid or
              unenforceable in whole or in part. Neither the Company, nor any of
              its Subsidiaries has received any written legal opinion or
              notification from any regulatory authorities that any of their
              respective Intellectual Property is invalid, unregistrable or
              unenforceable. The Company has not abandoned any trademark,
              copyright or other applications relating to the Proprietary
              Software.

       (k)    The Company has obtained all approvals necessary for exporting the
              Company Products outside the United States or Canada and importing
              the Company Products into any country in which the Company
              Products are now sold or licensed for use, and all such export and
              import approvals in the United States and Canada and throughout
              the world are valid, current and in full force and effect.

       (l)    Section 6.21 of the Disclosure Schedule sets forth a true, correct
              and complete list of all Proprietary Software and of any
              restrictions on the Company's right to use, modify, incorporate,
              bundle or distribute any Proprietary Software. Neither the Company
              nor any of its Subsidiaries have violated or are violating any
              license, sublicense, or agreement with respect to any Software.

       (m)    Subject to any agreed restrictions in connection with Licensed
              Software as set forth in the license agreement for such Licensed
              Software, the Company is entitled to make, use, sell, transmit,
              display, copy or otherwise reproduce, develop, distribute, bundle,
              modify or otherwise create derivative works regarding, market,
              license, sublicense and assign the Proprietary Software and the
              Company's Intellectual Property, and otherwise exploit all the
              rights related thereto, in the ordinary course of Company
              Business. With respect to each license or agreement by which the
              Company has obtained the rights to exploit the Intellectual
              Property rights of any other person, including the rights to make,
              use, sell, transmit, display, copy or otherwise reproduce,
              develop, distribute, bundle, modify or otherwise create derivative
              works regarding, market, license, sublicense or assign
              Intellectual Property or by which the Company has granted to any
              third party the right to so exploit Intellectual Property:

              (i)    such license or agreement is a valid, binding and
                     enforceable agreement of the Company or a Subsidiary of the
                     Company, as the case may be, and represents the entire
                     agreement between the parties thereto with respect to the
                     subject matter thereof;

              (ii)   subject to Section 6.21 of the Disclosure Schedule, the
                     consummation of the transactions contemplated by this
                     Agreement will not constitute a breach or default under
                     such license or agreement, or otherwise give any party
                     thereto a right to terminate or amend such license or
                     agreement;

              (iii)  with respect to each such license or agreement, (A) the
                     Company has not received any written notice of termination
                     or cancellation under such license or agreement, and no
                     party thereto has any right of termination or cancellation
                     thereunder except in accordance with its terms, (B) the
                     Company has not received any written notice of a breach or
                     default under such license or agreement which breach or
                     default has not been cured or is not curable, and (C) the
                     Company has not granted to any other person any rights,
                     adverse or otherwise, under such license or agreement,
                     except as permitted therein; and

              (iv)   to the knowledge of the Company and the Vendors, no other
                     party to such license or agreement is in breach or default
                     thereof and no event has occurred that, with notice or
                     lapse of time would constitute such a breach or default or
                     permit termination, modification or acceleration under such
                     license or agreement.

       (n)    No person has revoked the right of the Company to display,
              reproduce, distribute, create derivative works regarding, market,
              license, sublicense or otherwise exploit the use of any
              Intellectual Property owned or controlled by such person.

       (o)    The Company Products function and perform in all material respects
              in accordance with the functional and performance characteristics
              attributed to the Company Products in the Company's marketing
              materials and in the related technical specifications for the time
              periods under their applicable warranties. Section 6.21 of the
              Disclosure Schedule contains a complete listing of all warranty
              claims that required repayment to any customers of the Company
              during the twenty-four (24) month period preceding the Closing
              Date. To the knowledge of the Company and the Vendors, the
              Software is free of all viruses, worms, Trojan horses and other
              known contaminants, and the Software has no problems known to the
              Vendors that following Closing would result in (i) gross revenue
              derived from the sale of Company Products for the 12-month period
              ending October 31, 2003 to decrease by more than 25% as compared
              to the 12-month period ending October 31, 2002, or (ii) the value
              of warranty claims on sold Company Products to exceed 10% of the
              value of the revenues derived from the sale of such Company
              Products over the 12-month period ending on the first anniversary
              of the Closing Date.

       (p)    All Proprietary Software and, to the knowledge of the Company and
              the Vendors, all Licensed Software which forms a part of the
              Company's or its Subsidiaries' current product offerings or in
              respect of which a warranty claim could be made, is Year 2000
              Compliant, and to the knowledge of the Company and the Vendors,
              all other software currently used by the Company in the ordinary
              course of its business is Year 2000 Compliant.

       (q)    Neither the Company nor any of its Subsidiaries have received
              notice of, nor, to the knowledge of the Company and the Vendors,
              is there any law, regulation, order, action or proceeding (other
              than export regulations of general application not specifically
              pertaining to software or encryption) that restricts, or that
              could reasonably be expected to restrict in any manner, the
              development, use, export, import, transfer or licensing of any of
              the Company Products or the Company's Intellectual Property or
              that could reasonably be expected to affect the validity, use,
              registration or enforceability of any of the Company's
              Intellectual Property.

       (r)    Section 6.21 of the Disclosure Schedule sets forth the current
              standard Warranty Obligations contained in the Company's standard
              licensing agreement and a true, correct and complete list of (a)
              all contracts containing other Warranty Obligations individually
              exceeding $100,000 in force and effect that have not been
              contained in the Company's standard form agreements and the
              duration of each such other Warranty Obligation, (b) each of the
              material Warranty Obligations which is, to the knowledge of the
              Company and the Vendors, the subject of any dispute or threatened
              dispute, and (c) any unsatisfied material claims under any
              Warranty Obligations. None of the employees or agents of the
              Company or any of its Subsidiaries are authorized to undertake
              obligations to any

              customer or other person in excess of such Warranty Obligations
              other than pursuant to the terms of contracts for professional
              services engagements for training, installation and implementation
              services provided by the Company and/or its Subsidiaries. The
              Financial Statements reflect adequate reserves for Warranty
              Obligations in accordance with GAAP.

       (s)    The computer system or other similar device used by the Electronic
              Documents System operates properly, or if not, the fact of its
              operating improperly does not affect the integrity of any
              electronic document in such a way as to materially adversely
              affect the Company Business and there are no other reasonable
              grounds to doubt the integrity of the Electronic Documents System.

       (t)    None of the Proprietary Software or, to the knowledge of the
              Vendors or the Company, Licensed Software is subject to any
              "copyleft" or other similar obligation or condition (including any
              obligation or condition under any "open source" license such as
              the GNU Public License, Lesser GNU Public License or Mozilla
              Public License) that (i) could require, or could condition the use
              or distribution of such Proprietary Software or Licensed Software
              on, the use, disclosure, licensing or distribution of any source
              code for any portion of such Proprietary Software or Licensed
              Software, or (ii) could require the use, disclosure, licensing or
              distribution of any Proprietary Software or, to the knowledge of
              the Company and the Vendors, Licensed Software at a reduced or
              discounted royalty rate or for free.

              outside of Canada, and no claim has ever been made by a taxing
              authority of any jurisdiction in which the Company does not file
              Tax returns that the Company is or may be subject to taxation by
              that jurisdiction.

              of operations, activities or transactions occurring prior to the
              Closing Date.

              in Sections 10.1(a) and 10.1(b), but not in limitation of the
              obligations of the Vendors under Section 10.7, cash in the amount
              of Five Million Two Hundred Thousand Dollars ($5,200,000) (the
              "Escrow Amount") shall be withheld in the aggregate from the
              Purchase Price by the Purchaser and from the Option Holders Base
              Payment by the Company, and deposited by the Purchaser and the
              Company in the Escrow Fund on the Closing Date. The Escrow Amount
              shall consist of (i) the Vendors' ratable share of the Escrow
              Amount, (ii) the Selling Option Holders' ratable share of the
              Escrow Amount, and (iii) the ratable share of the Escrow Amount in
              respect of the Remaining Shareholders and the Remaining Option
              Holders, subject to the provisions of Sections 3.10(d) and (e).
              The Purchaser shall also deposit in the Escrow Fund the amounts,
              if any, to be deposited therein in accordance with Sections
              2.4(a)(iii)(B) and 2.7(B).

       (d)    The Escrow Fund shall be governed by the terms set forth herein
              and in the Escrow Agreement and shall be held by the Escrow Agent
              for the benefit of the Purchaser, the Vendors, the Selling Option
              Holders and, subject to the provisions

<PAGE>

                                      -61-

              of Sections 3.10(d) and (e), the Remaining Shareholders and the
              Remaining Option Holders.

       (e)    The parties acknowledge and agree that (i) the Purchaser shall be
              entitled to obtain compensation for Damages from the Escrow Fund
              for any breach of any representation or warranty set forth in
              Article 6 and for any breach by the Company of any covenant,
              agreement or other obligation of the Company hereunder to be
              performed on or before Closing, in each case to the full extent of
              the Escrow Fund and without regard to the beneficial entitlement
              in the Escrow Fund of the Vendors, the Selling Option Holders and,
              subject to the provisions of Sections 3.10(d) and (e), the
              Remaining Shareholders and the Remaining Option Holders, or the
              amount of Escrow Monies contributed or accruing to the Escrow Fund
              by or for the benefit of any such person, and (ii) each of the
              Vendors, the Selling Option Holders and, subject to the provisions
              of Sections 3.10(d) and (e), the Remaining Shareholders and the
              Remaining Option Holders shall be fully liable for such Damages to
              the full extent of its share of the Escrow Fund. The Parties
              further acknowledge and agree that the Purchaser shall be entitled
              to obtain compensation for Damages from the Escrow Fund for any
              breach by any Vendor of any representation or warranty of such
              Vendor set forth in Article 7 and for any breach by any Vendor of
              any covenant, agreement or other obligation of such Vendor
              hereunder, in each case to the full extent of such Vendor's share
              of the Escrow Fund.

       (f)    The Purchaser shall, subject to the provisions of Sections 3.10(d)
              and (e), be entitled to the share of the Escrow Fund held in
              respect of the Remaining Shareholders and the Remaining Option
              Holders until the Purchaser shall, as contemplated in Section
              3.10(d) or (e), as the case may be, have given notice to the
              Escrow Agent that such Remaining Shareholders or Remaining Option
              Holders are entitled to their ratable share of the Escrow Fund
              (determined in accordance with the Allocation Schedule).

10.2   ATTEMPT TO RESOLVE CONFLICTS; ARBITRATION

       (a)    All claims by the Purchaser pursuant to Article 10.1 shall be made
              in writing to the Vendors' Agent. The Vendors' Agent shall have
              thirty (30) days from the receipt of any such claim to deliver to
              the Purchaser an objection in writing to the claim, failing which
              the claim shall be deemed to be accepted. The Purchaser shall have
              thirty (30) days from the receipt of an objection from the
              Vendors' Agent to deliver to the Vendors' Agent a written response
              to the objection, failing which the Purchaser's claim shall be
              deemed to be abandoned. On receipt of a response to the objection,
              the Vendors' Agent and the Purchaser shall attempt in good faith
              to resolve the dispute. If the Vendors' Agent and the Purchaser
              are able to resolve the dispute, a memorandum setting forth the
              terms of the resolution shall be prepared and signed by both
              parties and shall, if a claim is being made against the Escrow
              Fund, be furnished to the Escrow Agent. The Escrow Agent shall be
              entitled to rely on any such memorandum and shall distribute the
              Escrow Monies in accordance with the terms thereof.

<PAGE>

                                      -62-

       (b)    In the event that any claim by the Purchaser is not resolved
              within thirty (30) days following delivery of a response to an
              objection in accordance with subparagraph (a) hereof, the
              Purchaser may, by delivery of a notice in writing to the Vendors'
              Agent within fifteen (15) days of the end of the said thirty (30)
              day period, require that the dispute be put to arbitration. In the
              event that Damages which are the subject matter of the Purchaser's
              claim are at issue in pending litigation with a third party, then
              the arbitration shall not, unless the Vendors' Agent otherwise
              agrees, be commenced until such litigation is resolved. Within
              fifteen (15) days after receipt by the Vendors' Agent of a notice
              of requirement to arbitrate, the Purchaser and the Vendors' Agent
              shall select a single mutually acceptable arbitrator. If they are
              unable to agree on a single arbitrator within such fifteen (15)
              day period, either one of them may apply to a judge sitting in
              motions court in the Ontario Superior Court of Justice at Toronto
              for appointment of the arbitrator.

       (c)    Any arbitration hearing constituted pursuant to this Section 10.2
              shall be held in the City of Toronto in accordance with the
              Arbitration Act (Ontario). The decision of the arbitrators shall
              be binding and conclusive upon the parties. A true and correct
              copy of such decision shall be delivered by the parties to the
              Escrow Agent and shall be the Escrow Agent's sufficient authority
              to disburse Escrow Monies from the Escrow Fund in accordance with
              the Escrow Agreement and such decision.

       (d)    The parties hereto irrevocably attorn to the jurisdiction of the
              Courts of Ontario with respect to any issue arising pursuant to
              constitution or conduct of the arbitration contemplated by this
              Section 10.2 and agree that all proceedings with respect to
              constitution or conduct of the arbitration contemplated by this
              Section 10.2 or the enforcement of any arbitration award shall be
              brought before the Ontario Superior Court of Justice at Toronto,
              Ontario.

10.3   VENDORS' AGENT

       (a)    Kiessling is constituted and appointed as agent ("Vendors' Agent")
              for and on behalf of the Vendors to give and receive all notices
              and communications under or in connection with this Agreement and
              the Escrow Agreement, to make all determinations under this
              Agreement and the Escrow Agreement for and on behalf of the
              Vendors or any of them (including the waiver of any conditions
              precedent as provided in Section 5.6), to authorize delivery to
              the Purchaser of the Escrow Monies from the Escrow Fund in
              satisfaction of claims by the Purchaser, to settle any other
              claims for indemnification, to object to such withdrawal, to agree
              to, negotiate, enter into settlements and compromises of, and
              comply with orders and awards of arbitrators and/or courts with
              respect to such claims, and to take all actions necessary or
              appropriate in the judgment of the Vendors' Agent for the
              accomplishment of the foregoing. Such agency may be changed after
              the Closing Date by the Vendors holding a majority of the
              beneficial interest of the Escrow Fund from time to time upon not
              less than ten (10) days' prior notice to the Purchaser. In the
              event of the death or incapacity of Kiessling, Lycklama (or

<PAGE>

                                      -63-

              such other person as Lycklama shall notify Purchaser of in
              writing) shall immediately and without further action by the
              Vendors be constituted and appointed as the new Vendors' Agent,
              and shall thereupon execute a counterpart of the Escrow Agreement.
              No bond shall be required of the Vendors' Agent, and the Vendors'
              Agent shall receive no compensation for its services. Notices and
              communications to and from the Vendors' Agent shall constitute
              notice to and from, respectively, each of the Vendors and, prior
              to the Closing, the Company.

       (b)    The Vendors' Agent shall not be liable for any act done or omitted
              hereunder as Vendors' Agent while acting in good faith and in the
              exercise of reasonable judgment, and any act done or omitted
              pursuant to the advice of counsel shall be conclusive evidence of
              such good faith. The Vendors shall severally, in proportion to
              their ownership of the Company Shares immediately prior to the
              sale of such shares to the Purchaser, indemnify the Vendors' Agent
              and hold it harmless against any loss, liability or expense
              incurred without gross negligence or bad faith on the part of the
              Vendors' Agent and arising out of or in connection with the
              acceptance or administration of its duties hereunder.

10.4   ACTIONS OF THE VENDORS' AGENT

       Any decision, act, consent or instruction of the Vendors' Agent shall
constitute a decision of all of the Vendors and, prior to the Closing, the
Company, and shall be final, binding and conclusive upon each Vendor and, prior
to the Closing, the Company, and the Escrow Agent and the Purchaser may rely
upon any decision, act, consent or instruction of the Vendors' Agent as being
the decision, act, consent or instruction of each and every such Vendor and,
prior to the Closing, the Company. The Escrow Agent and the Purchaser shall be
relieved from any liability to any person for any acts done by the Purchaser in
accordance with such decision, act, consent or instruction of the Vendors'
Agent.

10.5   THIRD-PARTY CLAIMS AND DISSENT RIGHTS

       (a)    In the event that a third party asserts or threatens a claim which
              the Purchaser believes may result in a demand against the Escrow
              Fund, the Purchaser shall notify the Vendors' Agent of such claim,
              and the Vendors' Agent on behalf of the Vendors shall be entitled,
              at the Vendors' expense, to participate in any defense of such
              claim. Unless the Vendors' Agent elects to assume such defense
              (with counsel reasonably acceptable to the Purchaser, and provided
              that the Vendors have reasonable means to put on such a defense),
              the Purchaser shall have the right to settle any such claim (with
              its own counsel); provided that the Purchaser may not effect the
              settlement of any such claim without the consent of the Vendors'
              Agent, which consent shall not be unreasonably withheld. In the
              event that the Vendors' Agent has consented to any such
              settlement, the Vendors' Agent and the Vendors shall have no power
              or authority to object under any provision of this Article 10 or
              the Escrow Agreement to the amount of any claim by the Purchaser
              against the Escrow Fund for indemnity with respect to such
              settlement. The Purchaser and the Company shall use reasonable
              commercial efforts to mitigate the amount of any such claim.

<PAGE>

                                      -64-

       (b)    In the event that any holder or holders of Company Shares exercise
              their rights under section 185 of the Business Corporations Act
              (Ontario), (i) the Purchaser shall notify the Vendors' Agent of
              such exercise of rights, (ii) the Company shall allow the Vendors'
              Agent and its representatives to assist representatives of the
              Company in responding to such exercise of rights and the
              opportunity to review and comment on proposed submissions by the
              Company in connection with such exercise of rights, and (iii) the
              Company shall not make an offer to pay for such holders' Company
              Shares or otherwise agree with such holders' as to the fair value
              of such holders' Company Shares without the consent of the
              Vendors' Agent, not to be unreasonably withheld, unless such offer
              or agreement specifies an amount which would not trigger the
              Purchaser's rights under paragraph 8 of Schedule H

10.6   LIMITATIONS

       (a)    The Purchaser may not receive any funds pursuant to the indemnity
              provided for in Section 10.1 or from the Escrow Fund and shall not
              otherwise be entitled to any indemnification for Damages under
              this Article 10 (other than as provided in Section 10.1(b)) unless
              and until the aggregate of the Damages claimed is at least One
              Hundred Thousand Dollars ($100,000) (the "Threshold"), provided
              that if the aggregate amount of the Damages claimed is at least
              equal to the Threshold, the Purchaser shall be entitled to receive
              funds pursuant to the indemnity provided for in Section 10.1 or
              Escrow Monies equal to the full amount of any and all Damages,
              including the initial Damages up to the Threshold. Notwithstanding
              the foregoing, the parties acknowledge and agree that the
              Threshold shall not be applicable to, and the Vendors shall be
              fully liable for (i) any and all Company Transaction Expenses not
              applied to reduce the Purchase Price pursuant to Section 2.2(a),
              (ii) any and all amounts owing to the Purchaser pursuant to
              Section 2.7(c) claimed by the Purchaser pursuant to Section
              2.4(a)(iii)(B) and, (iii) any and all amounts necessary to satisfy
              the indemnifications set forth in Section 10.1(b).

       (b)    The parties understand and agree that the liability of the Vendors
              for the breach of any representation, warranty, covenant,
              agreement or other obligation under this Agreement, including the
              indemnity obligations of the Vendors under this Article 10 and
              arising under Section 10.1(a), shall terminate on the date that
              is:

              (i)    two (2) years following the Closing Date with respect to
                     claims based on a breach of any of the representations and
                     warranties set forth in Sections 6.1, 6.2, 6.21, 7.1 or
                     7.2;

              (ii)   four (4) years following the Closing Date or, if later with
                     respect to any item, the applicable statute of limitations
                     for such item, with respect to claims based on a breach of
                     any of the representations and warranties set forth in
                     Section 6.23; and

              (iii)  one (1) year following the Closing Date for all other
                     claims;

<PAGE>

                                      -65-

              except insofar as a claim for indemnification under this Article
              10 has been asserted and such claim has not been resolved on or
              prior to such date in accordance with the terms of this Agreement,
              the Escrow Agreement or otherwise, in which case the indemnity
              obligations of the Vendors relating to such dispute shall survive
              until the resolution of such dispute. Notwithstanding the
              foregoing or anything else contained in this Agreement, the
              parties acknowledge and agree that the time limitations set out
              above shall not be applicable to, and the Vendors shall be fully
              liable for, the indemnifications set forth in Section 10.1(b)
              regardless of when any Claims in respect thereof shall arise.

10.7   RECOURSE

       (a)    Notwithstanding anything contained herein, each Vendor shall
              remain severally liable to the extent of, but not greater than,
              its respective share of the Purchase Price for Damages arising
              from the breach of any representations, warranties, covenants,
              agreements or other obligations of the Company or such Vendor
              hereunder if the Escrow Fund is insufficient to satisfy such
              claims. If the Purchaser makes a claim for Damages hereunder, the
              claim shall be made against each Vendor based on an amount equal
              to its respective proportionate share of the Purchase Price
              multiplied by the amount of Damages being claimed and shall only
              seek Damages from any Vendor beyond its proportionate share of the
              Damages if the Purchaser is unable to recover Damages from any of
              the other Vendors within ninety (90) days after the date upon
              which the Purchaser becomes entitled to such Damages (subject, for
              greater certainty, to the maximum liability stated in the first
              sentence of this Section). Nothing herein shall limit the
              Purchaser's right to seek recourse against any person, including
              any Vendor, for claims based on fraud.

       (b)    Notwithstanding anything contained in this Agreement or any
              instrument or document relating hereto, each of the Vendors
              acknowledges and agrees that if the Closing occurs, none of the
              Vendors shall have any recourse of any kind whatsoever against the
              Company for any breach by the Company of any representation,
              warranty, covenant, agreement or other obligation of the Company
              hereunder, and each Vendor hereby waives any and all rights and
              remedies, including any right of set-off, that it may have against
              the Company for any such breach. In furtherance and not in
              limitation of the foregoing, it is the intent of the Parties that
              each of the Purchaser and the Company and its Subsidiaries shall
              have the full benefit of the rights granted to them under this
              Article 10 and that such rights shall not be affected by any claim
              of any Vendor relating to any breach by the Company of any of its
              representations, warranties, covenants, agreements or other
              obligations hereunder.

       (c)    Notwithstanding anything contained herein, with respect any claim
              for indemnification under Section 10.1 or otherwise:

              (i)    Kiessling and K Holdco and his and its Affiliates shall be
                     jointly and severally liable for any such claim relating to
                     step 1 set forth in the Tax

<PAGE>

                                      -66-

                     Reorganization Memo or pursuant to Article 7 (to the extent
                     that Article 7 relates to K Holdco or Kiessling) and, for
                     greater certainty, Lycklama and L Newco shall have no
                     liability with respect to any such claim except as provided
                     in Section 10.7 (e);

              (ii)   Lycklama and L Newco and his and its Affiliates shall be
                     jointly and severally liable for any such claim relating to
                     steps 2, 6 and, subject to the limitations referred to in
                     paragraph 2 of Schedule H, step 10 set forth in the Tax
                     Reorganization Memo or pursuant to Article 7 (to the extent
                     that Article 7 relates to L Newco or Lycklama) or relating
                     to any liabilities or other obligations of L Holdco
                     existing prior to the Closing and, for greater certainty,
                     Kiessling and K Holdco shall have no liability with respect
                     to any such claim except as provided in Section 10.7(e);
                     and

              (iii)  the Vendors and their Affiliates shall be jointly and
                     severally liable for any such claim relating to steps 3, 4,
                     5, 7, 8, 9, 11 and 12 set forth in the Tax Reorganization
                     Memo.

       (d)    Nothing herein shall limit the Purchaser's right to seek recourse
              against any or all of the Vendors for any amounts owing to the
              Purchaser pursuant to Section 2.7(c) or require the Purchaser to
              first make a claim against the Escrow Fund to recover such
              amounts.

       (e)    Subject to Section 10.2, the Purchaser shall be entitled to
              satisfy any claims under Section 10.7(c) by claiming against the
              Escrow Fund and such a claim may extend beyond the interest of any
              particular Vendor in the Escrow Fund and may extend to the entire
              Escrow Fund; provided that the Purchaser has first attempted to
              claim against such Vendor outside of the Escrow Fund and has not
              received satisfaction of such claim within thirty (30) days of the
              date of the claim.

       (f)    Except as provided in Section 10.7(e), any claims made by the
              Purchaser under this Article 10 shall first be made against the
              Escrow Fund, and to the extent such claims are not satisfied from
              the Escrow Fund, the Purchaser may pursue such claims against the
              Vendors directly.

                                   ARTICLE 11
                                   TERMINATION

11.1   TERMINATION

       This Agreement may be terminated at any time prior to the Closing Date:

              (i)    by mutual written agreement of the Vendors, the Company and
                     the Purchaser;

              (ii)   by the Purchaser (provided the Purchaser is not in material
                     breach of this Agreement), if there has been a breach by
                     any of the Vendors or the Company of any representation,
                     warranty, covenant, agreement or other

<PAGE>

                                      -67-

                     obligation set forth in this Agreement on the part of any
                     of the Vendors or the Company which breach, if not cured,
                     would cause the condition set forth in Section 5.5(c) not
                     to be satisfied and which breach by its nature cannot be
                     cured by such Vendor or the Company, as the case may be;

              (iii)  by the Vendors (provided none of the Vendors or the Company
                     is in material breach of this Agreement), if there has been
                     a breach by the Purchaser of any representation, warranty,
                     covenant, agreement or other obligation set forth in this
                     Agreement on the part of the Purchaser which breach, if not
                     cured, would cause the condition set forth in Section
                     5.6(a) not to be satisfied and which breach by its nature
                     cannot be cured by the Purchaser;

              (iv)   by the Purchaser, by giving notice to the Vendors' Agent,
                     if the Closing shall not have occurred on or before
                     November 27, 2002 by reason of the failure of any condition
                     precedent under Section 5.4 or 5.5 (unless the failure
                     results primarily from a breach by the Purchaser of any
                     representation, warranty, covenant, agreement or other
                     obligation of the Purchaser contained in this Agreement or
                     the Purchaser's failure to fulfill a condition precedent to
                     Closing);

              (v)    by the Vendors, by giving notice to the Purchaser, if the
                     Closing shall not have occurred on or before November 27,
                     2002 by reason of the failure of any condition precedent
                     under Section 5.4 or 5.6 (unless the failure results
                     primarily from a breach by any of the Vendors or the
                     Company of any representation, warranty, covenant,
                     agreement or other obligation of any of the Vendors or the
                     Company contained in this Agreement or failure of such
                     Vendor or the Company, as the case may be, to fulfill a
                     condition precedent to Closing); or

              (vi)   by the Vendors or the Purchaser:

                     (A)    if any permanent injunction or other order of a
                            court or other competent authority preventing the
                            consummation of the transactions contemplated in
                            this Agreement shall have become final and
                            non-appealable; or

                     (B)    if there shall be any final action taken, or any
                            statute, rule, regulation or order enacted,
                            promulgated or issued or deemed applicable to the
                            consummation of the transactions contemplated in
                            this Agreement by any Governmental Authority which
                            would make consummation of the transactions
                            contemplated in this Agreement illegal or which
                            would prohibit the Purchaser's ownership or
                            operation of all or a material portion of the
                            Company Business or the Principal Assets, or compel
                            the Purchaser to dispose of or hold separately all
                            or a material portion of the Company Business or the
                            Principal Assets.

              rights or any other rights of any kind in any client, customer,
              Affiliate, shareholder, officer, director, employee or partner of
              any party or any other person unless specifically provided
              otherwise herein, and, except as so provided, all provisions

       (b)    No failure by any party to exercise, and no delay by any party in
              exercising, any right, power or remedy hereunder shall impair any
              right, power or remedy which such party may have, nor shall such
              delay be construed to be a waiver of any such

<PAGE>

                                      -72-

              rights, powers or remedies or an acquiescence in any breach or
              default under this Agreement or in connection with the
              transactions contemplated hereby. No waiver of any breach or
              default hereunder of any party shall be deemed a waiver of any
              default or breach subsequently occurring hereunder. Any agreement
              on the part of a party to any such extension or waiver shall be
              valid only if set forth in an instrument in writing signed on
              behalf of such party, and a waiver shall affect only the matter,
              and the occurrence thereof, specifically identified in the writing
              granting such waiver and shall not extend to any other matter or
              occurrence.

12.11  NON-MERGER; SURVIVAL

       All representations, warranties, covenants, agreements and other
obligations contained in this Agreement or in any other agreement or document
delivered pursuant hereto shall survive the Closing and shall not merge in any
conveyance, transfer, assignment or other document or instrument issuing
pursuant hereto or in connection herewith. Without limiting the generality of
the foregoing, the liability of a party for any breach of any of its
representations, warranties, covenants, agreements or other obligations
hereunder prior to the completion of the purchase and sale contemplated hereby
shall not be extinguished or in any manner diminished by such completion.

12.12  SEVERABILITY

       If any provision of this Agreement, or the application thereof, will for
any reason and to any extent be invalid or unenforceable, the remainder of this
Agreement and application of such provision to other persons or circumstances
will be interpreted so as reasonably to effect the intent of the parties. The
parties further agree to replace such void or unenforceable provision of this
Agreement with a valid and enforceable provision that will achieve, to the
extent possible, the economic, business and other purposes of the void or
unenforceable provision.

12.13  OTHER REMEDIES

       Except as otherwise provided herein, any and all remedies herein
expressly conferred upon a party will be deemed cumulative with and not
exclusive of any other remedy conferred hereby or by law or equity on such
party, and the exercise of any one remedy will not preclude the exercise of any
other.

12.14  ENTIRE AGREEMENT

       Except for the Confidentiality Agreements, this Agreement expresses and
constitutes the entire agreement among the parties with respect to the purchase
and sale of the Company Shares and Company Options and the other transactions
contemplated in this Agreement, and supersedes any previous agreements or
understandings with respect to the purchase and sale of the Company Shares and
Company Options, including the Summary of Proposed Terms dated August 27, 2002
among Quest, the Company, and Gregory J. Kiessling, Edward A. Lycklama, 976206

                                      -73-

Agreement and shall remain in full force and effect until terminated in
accordance with their respective terms.

12.15  SPECIFIC PERFORMANCE

       THE PARTIES AGREE THAT IRREPARABLE DAMAGE WOULD OCCUR IN THE EVENT THAT
ANY OF THE PROVISIONS OF THIS AGREEMENT WERE NOT PERFORMED IN ACCORDANCE WITH
THEIR SPECIFIC TERMS OR WERE OTHERWISE BREACHED. THE PARTIES SHALL BE ENTITLED
TO AN INJUNCTION OR INJUNCTIONS TO PREVENT BREACHES OF THIS AGREEMENT AND TO
ENFORCE SPECIFICALLY THE TERMS AND PROVISIONS HEREOF IN COURT, IN ADDITION TO
ANY OTHER REMEDY TO WHICH THEY ARE ENTITLED AT LAW OR IN EQUITY.

12.16  GUARANTEE OF QUEST

       If, for any reason, the Purchaser shall fail to perform any of its
obligations under this Agreement, Quest shall forthwith perform or cause the
