                  a)  The Purchase Price shall be adjusted downward at Closing

                      6.03(a) for which the Seller or the Purchaser does not

                      contract to be assigned as a result of the transactions
                      contemplated by this Agreement. "REVENUE MULTIPLE" shall

                      divided by the 1999 revenue of the Business set forth in
                      the audited financial statements, rounded to the nearest

          the Seller shall prepare and file or otherwise furnish in proper form

          respect to such corporations (except to the extent counsel for the
          Seller renders a legal opinion there is no reasonable basis in Law
          therefor or that a Tax Return cannot be so prepared and filed without
          being subject to penalties). With respect to any Tax Return required
          to be filed by the Purchaser or the Seller with respect to the
          Companies, the Subsidiaries and the Business and as to which an amount
          of Tax is allocable to the other party under Section 12.01 (b), the

          thereof) for the filing of such Tax Return, and such other party and
          its authorized representatives shall have the right to review and
          comment on such Tax Return and statement prior the filing of such Tax

          Seller, the Companies, the Subsidiaries and the Business for any
          taxable period ending on or before the Closing Date to the extent such
          Taxes exceed the amount, if any, accrued for such Taxes as current
          taxes payable on the Closing Balance Sheet, and the Purchaser shall so
          pay or cause to be paid Taxes for the Business for any taxable period
          after the Closing Date (subject to its right of indemnification from
          the Seller by the date set forth in Section 12.05 for Taxes
          attributable to the portion of any Tax period that includes the
          Closing Date pursuant to Sections 12.01 (a) and (b).

SECTION 12.03     REFUNDS

Any Tax refund (including any interest with respect thereto) relating to the
Seller, any Company, any Subsidiary or the Business for any taxable period prior
to the Closing Date (except for any refund included on the Reference Balance
Sheet, which shall be the property of the Purchaser, and if paid to the Seller,
shall be paid over promptly to the Purchaser) shall be the property of the

                                      -40-
<PAGE>
Seller, and if received by the Purchaser shall be payable promptly to the
Seller. Notwithstanding the foregoing sentence: (a) any Tax refund (or
equivalent benefit to the Seller through a reduction in Tax liability) for a
period before the Closing Date arising out of the carryback of a loss or credit
incurred by the Business in a taxable year ending after the Closing Date shall
be the property of the Purchaser and, if received by the Seller, shall be
payable promptly to the Purchaser; and (b) if, and to the extent that as of such
time, if any, as the Purchaser shall receive a refund that would be the property
of the Seller and payable to the Seller under the foregoing sentence, Taxes have
been asserted in writing that would be required to be indemnified by the Seller
hereunder, all or part of such refund up to an amount equal to 120% of such
asserted Taxes, shall be paid to the Seller.

SECTION 12.04     CONTESTS

     (a)  After the Closing, the Purchaser shall promptly notify the Seller in
          writing of any written notice of a proposed assessment or claim in an
          audit or administrative or judicial proceeding of the Purchaser which,
          if determined adversely to the taxpayer, would be grounds for
          indemnification under this Article XII; provided, however, that a
          failure to give such notice will not affect the Purchaser's right to
          indemnification under this Agreement except to the extent, if any,
          that, but for such failure, the Seller could have avoided all or a
          portion of the Tax liability in question.

     (b)  In the case of an audit or administrative or judicial proceeding that
          relates to periods ending on or before the Closing Date, provided that
          the Seller acknowledges in writing its responsibility under this
          Agreement to hold the Purchaser harmless against the full amount of
          any adjustment which may be made as a result of such audit or
          proceeding that relates to periods ending on or before the Closing
          Date (or, in the case of any taxable year that includes the Closing
          Date, against an adjustment allocable under Section 12.01 (b) to the
          portion of such year ending on or before the Closing Date), the Seller
          shall have the right at its expense to participate in and control the
          conduct of such audit or proceeding but only to the extent that such
          audit or proceeding relates solely to a potential adjustment for which
          the Seller has acknowledged its liability; the Purchaser also may
          participate in any such audit or proceeding and, if the Seller does
          not assume the defense of any such audit or proceeding, the Purchaser
          may defend the same in such manner as it may deem appropriate,
          including, but not limited to, settling such audit or proceeding after
          giving five days' prior written notice to the Seller setting forth the
          terms and conditions of settlement. In the event that issues relating
          to a potential adjustment for which the Seller has acknowledged its
          liability are required to be dealt with in the same proceeding as
          separate issues relating to a potential adjustment for which the
          Purchaser would be liable, the Purchaser shall have the right, at its
          expense, to control the audit or proceeding with respect to the latter
          issues.

                                      -41-
<PAGE>
     (c)  With respect to issues relating to a potential adjustment for which
          both the Seller (as evidenced by its acknowledgment under this Section
          12.04) and the Purchaser could be liable, (i) each party may
          participate in the audit or proceeding, and (ii) the audit or
          proceeding shall be controlled by that party which would bear the
          burden of the greater portion of the sum of the adjustment and any
          corresponding adjustments that may reasonably be anticipated for
          future Tax periods. The principle set forth in the preceding sentence
          shall govern also for purposes of deciding any issue that must be
          decided jointly (in particular, choice of judicial forum) in
          situations in which separate issues are otherwise controlled under
          this Article XII by the Purchaser and the Seller.

     (d)  Neither the Purchaser nor the Seller shall enter into any compromise
          or agree to settle any claim pursuant to any Tax audit or proceeding
          which would adversely affect the other party for such year or a
          subsequent year without the written consent of the other party, which
          consent may not be unreasonably withheld. The Purchaser and the Seller
          agree to cooperate in the defense against or compromise of any claim
          in any audit or proceeding.

Section 12.05     TIME OF PAYMENT.

Payment by the Seller of any amounts due under this Article XII in respect of
Taxes shall be made (a) at least three Business Days before the due date of the
applicable estimated or final Tax Return required to be filed by the Purchaser
on which is required to be reported income for a period ending after the Closing
Date for which the Seller is responsible under Sections 12.01 (a) and (b)
without regard to whether the Tax Return shows overall net income or loss for
such period, and (b) within three Business Days following an agreement between
the Seller and the Purchaser that an indemnity amount is payable, an assessment
of a Tax by a taxing authority. If liability under this Article XII is in
respect of costs or expenses other than Taxes, payment by the Seller of any
amounts due under this Article XII shall be made within five Business Days after
the date when the Seller has been notified by the Purchaser that the Seller has
a liability for a determinable amount under this Article XII and is provided
with calculations or other materials supporting such liability.

SECTION 12.06     COOPERATION AND EXCHANGE OF INFORMATION

Upon the terms set forth in Section 11.02, the Seller and the Purchaser shall
cooperate and provide each other with information as either of them reasonably
may request of the other in filing any Tax Return, amended Tax Return or claim
for refund, determining a liability for Taxes or a right to a refund of Taxes,
participating in or conducting any audit or other proceeding in respect of Taxes
or making representations to or furnishing information to parties subsequently
desiring to purchase all or a part of the Business from the Purchaser. Such
cooperation and information shall include providing copies of relevant Tax
Returns or portions thereof, together with accompanying schedules, related work
papers and documents relating to rulings or other determinations by Tax
authorities. The Seller shall make its employees available on a basis

                                      -42-

Business for each taxable period first ending after the Closing Date and for all
prior taxable periods until the later of (a) the expiration of the statute of
limitations of the taxable periods to which such Tax Returns and other documents
relate, without regard to extensions except to the extent notified by the other
party in writing of such extensions for the respective Tax periods, or (b) six
years following the due date (without extension) for such Tax Returns. Any
information obtained under this Section 12.06 shall be kept confidential in
accordance with the Letter Agreement except as may be otherwise necessary in
connection with the filing of Tax Returns or claims for refund or in conducting
an audit or other proceeding.

SECTION 12.07     CONVEYANCE TAXES

real property transfer or gains, sales, use, transfer, value added, stock
transfer, and stamp taxes, any transfer, recording, registration, and similar

transactions contemplated by this Agreement. The Seller, after the review and
consent by the Purchaser, shall file such applications and documents as shall
permit any such Tax to be assessed and paid on or prior to the Closing Date in
accordance with any available pre-sale filing procedure. The Purchaser shall
execute and deliver all instruments and certificates necessary to enable the
Seller to comply with the foregoing. The Purchaser shall complete and execute a
resale or other exemption certificate with respect to the inventory items sold
hereunder, and shall provide the Seller with an executed copy thereof.

         (a)  The Seller and the Purchaser shall treat all payments made by
              either to or for the benefit of the other (including any payments

              XII, under other indemnity provisions of this Agreement and for
              any misrepresentations or breach of warranties or covenants as
              adjustments to the Purchase Price or as capital contributions for
              Tax purposes and that such treatment shall govern for purposes
              hereof except to the extent that the laws of a particular
              jurisdiction provide otherwise, in which case such payments shall
              be made in an amount sufficient to indemnify the relevant party on
              an after-Tax basis.

              and warranties contained in Section 8.09, shall terminate at the
              close of business on the 120th day following the expiration of the
              applicable statute of limitations with respect to the Tax
              liabilities in question (giving effect to any waiver, mitigation
              or extension thereof).

         (c)  From and after the date of this Agreement, the Seller shall not
              without the prior written consent of the Purchaser (which may, in
              its sole and absolute discretion, withhold such consent) make, or
              cause or permit to be made, any Tax election that would affect the
              Business.

         (d)  For purposes of this Article XII, "the Purchaser" and "the
              Seller," respectively, shall include each member of the affiliated

         (e)  The Purchaser shall be entitled to recover professional fees and

hereby is subject to the satisfaction, on or before the Closing Date, of the
following conditions, any of which may be waived by the Purchaser in writing:

         (a)  Representations and Warranties. Each of the representations and

              true and correct in all material respects, in each case, as of the
              Closing Date with the same force and effect as though the same had
              been made on and as of the Closing Date, except for those given as
              of a particular date, which shall be true and correct in all
              material respects as of such date, and except for changes therein
              permitted or contemplated hereby.

         (b)  Covenants. The Seller and the Companies shall have performed and
              complied in all material respects with each of the covenants and
              provisions in this Agreement required herein to be performed or
              complied with by them between the date hereof and the Closing
              Date.

         (c)  Merger and Acquisition and Anti Trust Acts. The waiting period

              materially and adversely alter the transactions contemplated
              hereby which the Purchaser believes, in its reasonable discretion,
              is likely to render it impossible or unlawful to consummate the
              transactions contemplated by this Agreement or which could have a
              Material Adverse Effect or otherwise render inadvisable, in the
              Purchaser's reasonable discretion, the consummation of the
              transactions contemplated by this Agreement.

         (g)  Audited Balances. The Purchaser or its parent company shall have

              circumstance shall have occurred with respect to any Company, any
              Subsidiary which would constitute a Material Adverse Effect, and
              not any Company, nor Subsidiary shall have suffered any material
              loss or damages to any of its properties or assets whether or not
              covered by insurance, which change, loss or damage materially

              conduct its business.

         (i)  Intercompany Transfers. The Seller and the Companies shall have
              provided the Purchaser with true, complete and correct copies of
              all agreements, documents and instruments relating to the transfer
              of the Assets and Assumed Liabilities (but none of the Excluded
              Liabilities) of the Business to the Company, all of which shall be
              in form and substance satisfactory to the Purchaser.

         (j)  Works Council. The Purchaser has received approval of the Works
              Council, if any.

              material respects with each of the covenants and provisions in

                                   ARTICLE XIV

SECTION 14.02     PROTECTION OF THE BUSINESS

         (a)  In partial consideration of the payment of the Purchase Price, as
              set forth in Section 6.01, the Seller and the Purchaser agree
              that, for a period of five (5) years after the Closing (the
              "RESTRICTED PERIOD"), the Seller shall not engage, directly or
              indirectly, in any capacity, in any business anywhere in the world
              that offers secure computer-based testing services to any entity,
              person, company or organization (other than the Company or its
              Affiliates) or, without the prior written consent of the
              Purchaser, directly or indirectly, own an interest in, manage,
              operate, join, control, lend money or render financial or other
              assistance to or participate in or be connected with, as a
              partner, shareholder, consultant or otherwise, any Person that
              competes with the Purchaser, any Company, any Subsidiary or the
              Business in offering secure computer-based testing services;
              provided, however, that, for the purposes of this Section 14.02
              ownership of securities representing less than five (5) percent of
              the outstanding voting power of any competitor shall not be deemed
              to be in violation of this Section 14.02 so long as the Person
              owning such securities has no other connection or relationship
              with such competitor. Nothing in this Section 14.02 will prevent
              the Seller or its Affiliates (i) from providing, directly or
              indirectly, computer-based tests to persons who are provided
              educational services by the Seller or any of its Affiliates so
              long as such tests are ancillary to such educational services or
              to test its current or prospective employees or (ii) from
              conducting or engaging in, directly or indirectly, any business
              other than computer-based testing regardless of whether such
              business is also conducted or engaged in by the Purchaser, Thomson
              or their respective Affiliates. For purposes of this Section
              14.02(a), "secure" means any computer-based test requiring
              proctoring, with proctoring meaning having individuals physically
              present to monitor test taking, remote proctoring to monitor test
              taking or any other type of monitoring designed to ensure that the
              test takers follow guidelines set for the test being taken.

         (b)  Seller shall not, and will not permit any of its Affiliates to,
              directly or indirectly, solicit the employment of, attempt to
              employ, or employ any employee of the Business during the period
              commencing on the Closing Date and ending eighteen months
              thereafter; provided, however, that the forgoing shall not
              prohibit Seller from hiring any former employee of the Business
              (i) on any unsolicited basis or (ii) as the direct result of a
              general solicitation to the public or general advertising;
              provided further, that if at any time during the twelve months
              following the Closing the Seller proposes to hire a former
              non-clerical employee of the Business whose employment by the
              Business terminated voluntarily less than 90 days prior to such
              date, prior to hiring such individual the Seller will notify the
              Purchaser and give the Purchaser a reasonable opportunity to
              attempt to rehire such employee. In addition, the Seller and its
              Affiliates will not during such eighteen month period, engage or
              employ any person acting as a consultant to the Business on the
              Closing Date in a manner that

                                      -47-
<PAGE>
              would interfere with such consultant's ability to continue to
              perform services to the Business as required by the Business.

         (c)  The Restricted Period shall be extended by the length of any
              period during which the Seller is in breach of the terms of this
              Section 14.02.

         (d)  The Seller acknowledges that the covenants of the Seller set forth
              in paragraphs (a) through (c) of this Section 14.02 are an
              essential element of this Agreement and that, but for the
              agreement of the Seller to comply with these covenants, the
              Purchaser would not have entered into this Agreement. The Seller
              acknowledges that this Section 14.02 constitutes an independent
              covenant and shall not be affected by performance or
              nonperformance of any other provision of this Agreement by the
              Purchaser. The Seller has independently consulted with its counsel
              and after such consultation agrees that the covenants set forth in
              this Section 14.02 are reasonable and proper.

         (e)  The Seller agrees to contract with the Companies for any
              proctored, secure computer-based testing Seller may require in the
              future, provided that: (i) the Purchaser gives Seller most favored
              nation pricing for the type of testing to be delivered by the
              Company, and (ii) the Companies are then able to meet the
              specifications for such delivery of the tests.

SECTION 14.03     NON-COMPETITION BY PURCHASER AND GUARANTOR.

During the Restricted Period, the Purchaser and Thomson and their Affiliates
shall not provide in any STC any educational services that compete with any of
the educational services generally provided in Sylvan Learning Centers by the
Seller, its Affiliates, franchisees or other operators of Sylvan Learning
Centers; it being understood that this Section 14.03 is not intended to restrict
the Purchaser or Thomson and their Affiliates from conducting any business
activities in any locations other than STCs.

SECTION 14.04     USE OF INTELLECTUAL PROPERTY

         (a)  Except as set forth in Section 14.04 of the Disclosure Schedule,
              from and after the Closing, the Seller shall not use any of the
              owned Intellectual Property.

         (b)  As soon as possible after the Closing the Seller shall remove the
              name Prometric, and cause any of its Companies and Subsidiaries
              that use such name in their corporate names to amend its Charter
              Documents accordingly, to one not using any trademark, service
              mark, trade dress, logo, trade name or corporate name contained in
              the Intellectual Property or any trademark, servicemark, trade
              dress, logo, trade name, or corporate name similar or related
              thereto. As promptly as practicable following the Closing, the
              Seller shall remove or obliterate any Intellectual Property from

                                      -48-
<PAGE>
              letterheads and other materials remaining in its possession or
              under its control, and the Seller shall not use or put into use
              after the Closing any materials that bear any trademark, service
              mark, trade dress, logo, trade name or corporate name contained in
              the Intellectual Property.

         (c)  For a period of twelve months after the Closing, the Purchaser
              shall have the right to use the Sylvan name in combination with
              the name Prometric or as otherwise used by the Business prior to
              the Closing. The Purchaser understands and agrees that it is not
              acquiring any interest in the name "Sylvan" or any goodwill
              associated therewith. The Purchaser shall in no way represent that
              it is affiliated with SLS in the use of the Sylvan name as
              provided in this Section 14.04. SLS hereby grants the Purchaser a
              non-exclusive, royalty-free license to use the Sylvan name for the
              twelve months' period herein provided.


                                   ARTICLE XV
                   SURVIVAL OF REPRESENTATIONS AND WARRANTIES;

(d) the covenants and agreements made in this Agreement that are to be performed
in whole or in part subsequent to the Closing Date and that do not, by their
terms, expire on a date certain, and Articles XV, XVI and XVII of this Agreement

claim has been given prior to the expiration of the applicable representations
and warranties by the Purchaser to the Seller, then the relevant representations
and warranties shall survive as to such claim until the claim has been finally
resolved.

SECTION 15.02     INDEMNIFICATION.

         (a)  By Seller and SLS, Inc. The Seller and SLS, Inc. shall jointly and
              severally indemnify and hold the Purchaser, the Companies, the
              Subsidiaries and their Affiliates and Representatives harmless
              from and against any and all losses, claims, demands, liabilities,
              obligations, damages, deficiencies, assessments, judgments,

                                      -49-
<PAGE>
              payments, penalties, costs and expenses (including, without
              limitation, reasonable attorneys' fees, any amounts paid in
              investigation, defense or settlement of any of the foregoing and
              interest) ("DAMAGES") incurred in connection with, arising out of,
              resulting from or incident to, (i) any breach of the
              representations and warranties of the Seller or the Subsidiaries
              set forth in Articles VIII and XI or on the schedules or
              certificates delivered in connection herewith, or (ii) any breach
              of any covenant or agreement made by the Seller, the Companies or
              the Subsidiaries in this Agreement.

         (b)  By Purchaser. The Purchaser agrees to indemnify and hold the
              Seller and its Affiliates and Representatives harmless from and
              against any and all Damages incurred in connection with, arising
              out of, resulting from or incident to, (i) any breach of the
              representations and warranties of the Purchaser set forth in
              Article VII or on the schedules or certificates delivered in
              connection herewith, (ii) any breach of any covenant or agreement
              made by the Purchaser in this Agreement, or (iii) operation of the
              business of the Subsidiaries after the Closing Date.

         (c)  Damages. The term "DAMAGES" as used in this Section 15.02 is not
              limited to matters asserted by third parties against any
              indemnified party, but includes Damages incurred or sustained by
              any indemnified party in the absence of third party claims.

         (d)  Limitations on Indemnification. The persons or entities
              indemnified pursuant to Section 15.02(a) and Section 10.02(a) of
              the Stock Purchase Agreement shall not assert any claim other than
              a Third Person claim for indemnification hereunder or under
              Section 10.02(d) of the Stock Purchase Agreement unless and until,
              and solely to the extent that, the aggregate of all such claims
              shall exceed U.S.$ 2,000,000 (the "DEDUCTIBLE"), in which event
              such indemnification shall be effective with respect to all
              Damages, in excess of the Deductible; provided, however, that this
              limitation shall not apply to (i) claims of or relating to fraud
              or willful misrepresentation or willful misconduct by any party or
              (ii) any breach of the representations contained in Sections 8.01,
              9.01 and 9.02 hereof or Sections 3.01, 4.01 and 4.02 of the Stock
              Purchase Agreement. In addition to the other limitations of this
              Section 15.02 (d), the amount of any indemnification under this
              Agreement and the Stock Purchase Agreement will be reduced by any
              insurance proceeds paid to the indemnifying party as a result of
              its Damages. The indemnifying party will be obligated to submit to
              its insurance carrier all coverable claims and pursue such claims
              against its insurance carrier in good faith. In addition to the
              other limitations described in this Section 15.02(d), it is
              expressly understood that the obligations of the Seller to pay any
              amounts for indemnification under Section 15.02(a) and Section
              10.2 of the Stock Purchase Agreement shall not exceed the
              "INDEMNIFICATION LIMIT" (as defined herein); provided, however,
              that this limitation shall not apply to (i) claims of or relating
              to fraud or willful misrepresentation or willful misconduct by any
              party, and (ii) any breach of the representations contained in
              Sections 8.01, 9.01 and 9.02 hereof and Sections 3.01, 4.01 and
              4.02 of the Stock Purchase Agreement. For purposes of

              this Section 15.02 (d), the "INDEMNIFICATION LIMIT" shall be 50%
              of the Purchase Price hereunder plus 50% of the Purchase Price
              under the Stock Purchase Agreement. No person shall be entitled to
              indemnification under this Section 15.02 if and to the extent that
              such person's claim for indemnification is directly or indirectly
              related to a breach by such person of any representation,
              warranty, covenant or other agreement set forth in this Agreement.

         (e)  Defense of Claims; Third Person Claims.
             ---------------------------------------
              (i)  If a claim for Damages (a "CLAIM") is to be made by a party
                   entitled to indemnification hereunder against the
                   indemnifying party, the party claiming such indemnification
                   shall give written notice (a "CLAIM NOTICE") to the
                   indemnifying party as soon as practicable after the party
                   entitled to indemnification becomes aware of any fact,
                   condition or event which may give rise to Damages for which
                   indemnification may be sought under this Section 15.02. Such
                   Claim Notice shall specify the nature and amount of the Claim
                   asserted, if actually known to the party entitled to
                   indemnification hereunder. If any lawsuit or enforcement
                   action is filed against any party entitled to the benefit of
                   indemnity hereunder, written notice thereof shall be given to
                   the indemnifying party as promptly as practicable (and in any
                   event within 15 days after the service of the citation or
                   summons). Subject to the limitations of this Section 15.02,
                   the failure of any indemnified party to give timely notice
                   hereunder shall not affect rights to indemnification
                   hereunder, except to the extent that the indemnifying party
                   demonstrates actual damage caused by such failure. After such
                   notice, if the indemnifying party shall acknowledge in
                   writing to the indemnified party that the indemnifying party
                   shall be obligated under the terms of its indemnity hereunder
                   in connection with such lawsuit or action, then the
                   indemnifying party shall be entitled, if it so elects at its
                   own cost and expense, (A) to take control of the defense and
                   investigation of such lawsuit or action, (B) to employ and
                   engage attorneys of its own choice, who shall be reasonably
                   satisfactory to the indemnified party, to handle and defend
                   the same unless the named parties to such action or
                   proceeding include both the indemnifying party and the
                   indemnified party and the indemnified party has been advised
                   in writing by counsel that there may be one or more legal
                   defenses available to such indemnified party that are
                   different from or additional to those available to the
                   indemnifying party, in which event the indemnified party
                   shall be entitled, at the indemnifying party's cost and
                   expense, to separate counsel of its own choosing, and (C) to
                   compromise or settle such claim, which compromise or
                   settlement shall be made only with the written consent of the
                   indemnified party, such consent not to be unreasonably
                   withheld or delayed; provided, however, that any such
                   compromise or settlement shall give each Indemnified Party a
                   full, complete and unconditional release of any and all
                   liability by all relevant parties relating thereto. If the
                   indemnifying party fails to assume the defense of such claim
                   within thirty (30) calendar days after receipt of the Claim
                   Notice, the indemnified party against which such claim has
                   been asserted will (upon

                                      -51-
<PAGE>
                   delivering notice to such effect to the indemnifying party)
                   have the right to undertake, at the indemnifying party's cost
                   and expense, the defense, compromise or settlement of such
                   claim on behalf of and for the account and risk of the
                   indemnifying party; provided, however, that such Claim shall
                   not be compromised or settled without the written consent of
                   the indemnifying party, which consent shall not be
                   unreasonably withheld or delayed. In the event the
                   indemnified party assumes the defense of the claim, the
                   indemnified party will keep the indemnifying party reasonably
                   informed of the progress of any such defense, compromise or
                   settlement. The indemnifying party shall be liable for any
                   settlement of any action effected pursuant to and in
                   accordance with and subject to the limitations of this
                   Section 15.02 and for any final judgment (subject to any
                   right of appeal).

              (ii) In the event that any action, suit, proceeding or
                   investigation relating hereto or to the transactions
                   contemplated by this Agreement is commenced, the parties
                   hereto agree to reasonably cooperate to defend against and
                   respond thereto and make available to each other such
                   personnel, witnesses, books, records, documents or other
                   information within its control that are reasonably necessary
                   or appropriate for such defense.

              (iii)Promptly after any party hereto (the "INDEMNIFIED PARTY") has
                   received notice of or has Knowledge of any claim by a person
                   not a party to this Agreement ("THIRD PERSON"), of the
                   commencement of any action or proceeding by a Third Person,
                   the Indemnified Party shall, as a condition precedent to a
                   claim with respect thereto being made against any party
                   obligated to provide indemnification pursuant to this Section
                   15.02 (the "INDEMNIFYING PARTY"), give the Indemnifying Party
                   written notice of such claim or the commencement of such
                   action or proceeding as soon as practicable. Such notice
                   shall state the nature and the basis of such claim and a
                   reasonable estimate of the amount thereof. Subject to the
                   limitations of this Section 15.02, the failure of any
                   Indemnified Party to give timely notice hereunder shall not
                   affect rights to indemnification hereunder, except to the
                   extent that the Indemnifying Party demonstrates actual damage
                   caused by such failure. The Indemnifying Party shall have the
                   right to defend and settle, at its own expense and by its own
                   counsel who shall be reasonably satisfactory to the
                   Indemnified Party, any such matter so long as the
                   Indemnifying Party pursues the same in good faith and
                   diligently, provided that the Indemnifying Party shall not
                   settle any proceeding without the written consent of the
                   Indemnified Party, such consent not to be unreasonably
                   withheld or delayed; and provided, further, that any such
                   compromise or settlement shall give each Indemnified Party a
                   full, complete and unconditional release of any and all
                   liability by all relevant parties relating thereto. If the
                   Indemnifying Party undertakes to defend or settle, it shall
                   promptly notify the Indemnified Party of its intention to do
                   so, and the Indemnified Party shall reasonably cooperate, at
                   the

                                      -52-
<PAGE>
                   Indemnifying Party's expense, with the Indemnifying Party and
                   its counsel in the defense thereof and in any settlement
                   thereof. If the Indemnifying Party desires to accept a final
                   and complete settlement of any such Third Person claim that
                   gives each Indemnified Party a full, complete and
                   unconditional release of any and all liability by all
                   relevant parties relating thereto and the Indemnified Party
                   refuses to consent to such settlement, then the Indemnifying
                   Party's liability under this Section with respect to such
                   Third Person claim shall be limited to the amount so offered
                   in settlement to said Third Person plus all indemnifiable
                   costs and expenses incurred to date, the Indemnifying Party
                   shall be relieved of its duty to defend and shall tender the
                   Third Person claim back to the Indemnified Party, who shall
                   thereafter, at its own expense, be responsible for the
                   defense and negotiation of such Third Person claim. If the
                   Indemnifying Party does not undertake to defend such matter
                   to which the Indemnified Party is entitled to indemnification
                   hereunder, or fails diligently to pursue such defense, the
                   Indemnified Party may undertake such defense through counsel
                   of its choice, at the cost and expense of the Indemnifying
                   Party, and the Indemnified Party may settle such matter, and
                   the Indemnifying Party shall reimburse the Indemnified Party
                   for the amount paid in such settlement and any other
                   liabilities or expenses incurred by the Indemnified Party in
                   connection therewith, provided, however, that under no
                   circumstances shall the Indemnified Party settle any Third
                   Person claim without the written consent of the Indemnifying
                   Party, which consent shall not be unreasonably withheld or
                   delayed.

         (f)  Special Indemnification Regarding Excluded Liabilities. The Seller
              shall indemnify and hold harmless the Purchaser, the Company and
              their Affiliates and Representatives from and against any and all
              Excluded Liabilities. Notwithstanding any other provision
              contained herein, any amount paid by the Seller pursuant to this
              Section 15.02 (f) shall not be subject to the Deductible or
              includible in the Indemnification Limit.

         (g)  Exclusive Remedy. Except as provided in paragraph (i) below, the
              rights of indemnification provided to the Purchaser and the Seller
              in this Section 15.02 are intended to be the sole remedies of such
              parties for any claim by either the Purchaser against the Seller
              or by the Seller against the Purchaser, and the parties intend, to
              the maximum possible extent, to preclude any other claims, on
              whatever cause of action predicated.

         (h)  Tax Indemnification. Anything in this Article XV to the contrary
              notwithstanding, the rights and obligations of the parties with
              respect to indemnification for any and all Tax matters shall be
              governed by Article XII.

                      FEES AND EXPENSES; INJUNCTIVE RELIEF


SECTION 16.01     FEES AND EXPENSES.

Except as set forth in Section 15.02, all fees, including Broker Fees and
expenses incurred in connection with this Agreement and the transactions
contemplated hereby shall be paid by the party incurring such expenses, whether
or not such transactions are consummated.

SECTION 16.02     INJUNCTIVE RELIEF.

Each party hereto acknowledges that the other parties will be irreparably harmed
and that there will be no adequate remedy at law for any violation by any of
them of any of the covenants or agreements contained in this Agreement,
including, without limitation, the noncompetition agreement contained in Section
14.02 and the indemnities contained in Article XV. It is, accordingly, agreed
that, in addition to any other remedies which may be available upon the breach
of, or to prevent a breach of, any such covenants or agreements, each party
hereto shall have the right to obtain injunctive relief to restrain a breach or
threatened breach of, or otherwise to obtain specific performance of, the other
parties', covenants and agreements contained in this Agreement, in any case
without the necessity of posting a bond or other security.

Notwithstanding anything contained in this Agreement to the contrary, this
Agreement may be terminated:

         (a)  At any time on or prior to the Closing Date, by the mutual consent
              in writing of the Seller and the Purchaser.

         (b)  By either the Seller or the Purchaser, if the Closing shall not
              have occurred prior to June 30, 2000 unless (i) the parties have
              not then received any approvals under Hart-Scott-Rodino (as
              defined in the Stock Purchase Agreement) or any local merger and
              acquisition act or (ii) there is then pending any Action described
              in Section 13.01(f), in either which case the applicable date
              under this Section 17.01 (b) shall be extended to September 30,
              2000; provided, however, that the right to terminate this
              Agreement under this Section 17.01(b) shall not be available to
              any party whose failure to fulfill any obligation under this
              Agreement shall have been the cause of, or shall have resulted in,
              the failure of the Closing to occur prior to such date.

                                      -54-
<PAGE>
         (c)  The Purchaser may terminate this Agreement by giving written
              notice to the Seller at any time prior to the Closing Date if (i)

              contained in this Agreement, (ii) such breach, individually or in
              the aggregate, has had, or is reasonably likely to have a Material
              Adverse Effect on the Company or the Division or is reasonably
              likely to prevent or to materially burden or materially impair the
              ability of the Purchaser to consummate the transactions
              contemplated by this Agreement, or if there has been any failure
              on the part of the Seller Company to comply in all material
              respects with its obligations hereunder, and (iii) the Purchaser
              has notified the Seller of the breach, and the breach has
              continued without cure for a period of 30 days after the notice of
              breach.

         (d)  The Seller may terminate this Agreement by giving written notice
              to the Purchaser at any time prior to the Closing Date if (i) the
              Purchaser has breached any representation, warranty or covenant
              contained in this Agreement, (ii) such breach, individually or in
              the aggregate, has had, or is reasonably likely to have, a
              Material Adverse Effect on the Purchaser or is reasonably likely
              to prevent or to materially burden or materially impair the
              ability of the Purchaser to consummate the transactions
              contemplated by this Agreement, or if there has been any failure
              on the part of the Purchaser to comply in all material respects
              with their obligations hereunder, and (iii) the Seller has
              notified the Purchaser of the breach, and the breach has continued
              without cure for a period of 30 days after the notice of breach.


SECTION 17.02     CONSEQUENCES OF TERMINATION

In the event that this Agreement shall be terminated in accordance with this
Article XVII (a) each party shall redeliver all documents, work papers and other
material, and copies thereof, of any other party relating to the transactions

that would be considered "CONFIDENTIAL INFORMATION" under the Letter Agreement
concerning confidentiality by and between the Purchaser and the Seller dated

provided therein, and can be amended, supplemented or changed, and any provision
hereof can be waived, only by written instrument making specific reference to
this Agreement signed by the party against whom enforcement of any such
amendment, supplement, modification or waiver is sought. No waiver of any of the
provisions of this Agreement shall be deemed or shall constitute a waiver of any
other provision hereof (whether or not similar), nor shall such waiver
constitute a continuing waiver unless otherwise expressly provided.

that this Agreement and all rights and obligations hereunder may not be assigned

SECTION 18.06     SEVERABILITY.

In case any provision of this Agreement shall be invalid, illegal or
unenforceable, it shall, to the extent possible, be modified in such manner as
to be valid, legal and enforceable but so as to most nearly retain the intent of
the parties, and if such modification is not possible, such provision shall be
severed from this Agreement, and in either case the validity, legality and
enforceability of the remaining provisions of this Agreement shall not in any
way be affected or impaired thereby.

SECTION 18.07     CONSTRUCTION.

The parties have participated jointly in the negotiation and drafting of this
Agreement. In the event an ambiguity or question of intent or interpretation

and no presumption or burden of proof shall arise favoring or disfavoring any
party by virtue of authorship of any provision of this Agreement.

SECTION 18.08     GOVERNING LAW AND JURISDICTION

This Agreement shall be governed by and construed in accordance with the laws of
the Netherlands. Each of the parties hereto irrevocably consents to the service
of any process, pleading, notices or other papers by the mailing of copies
thereof by registered, certified or first class mail, postage prepaid, to such
party at such party's address set forth herein, or by any other method provided
or permitted under the laws of the Netherlands. Each party irrevocably and
unconditionally agrees and consents that any suit, action or other legal
proceeding arising out of or related to this Agreement shall be brought and
heard in the competent court in the Netherlands, and each party irrevocably
consents to personal jurisdiction in such court. To the extent that the
Purchaser has or hereafter may acquire any immunity from jurisdiction of any
court or from any legal process (whether through service or notice, attachment
prior to judgment, attachment in aid of execution, execution or otherwise) with
respect to itself or its property, the Purchaser hereby irrevocably waives such
immunity in respect of their obligations pursuant to this Agreement.
