                            STOCK PURCHASE AGREEMENT

                  THIS AGREEMENT (this "AGREEMENT") is made and entered into as
of this 16th day of February, 2001, by and among Semitool, Inc., a Montana
corporation (hereinafter referred to as "PARENT"), SEMY Engineering, Inc., a
Delaware corporation and wholly-owned subsidiary of Parent (hereinafter referred
to as "COMPANY"), and Brooks Automation, Inc., a Delaware corporation
(hereinafter referred to as "BUYER"). (Parent, Company and Buyer are hereinafter
referred to individually as a "PARTY," and collectively as the "PARTIES").

                                    RECITALS

                  WHEREAS, Parent owns all of the outstanding shares of capital
stock of Company and is willing to sell the Company Shares to Buyer; and

                  WHEREAS, Buyer wishes to acquire all of the Company Shares for
$36,000,000 in cash and 73,243 shares of Buyer's common stock, $.01 par value
(the "BUYER SHARES");

                                    AGREEMENT

                  NOW, THEREFORE, in consideration of the mutual premises and
the covenants, conditions, representations and warranties herein contained, the
Parties hereto agree as follows:

                                   ARTICLE 1

                     SALE AND TRANSFER OF THE COMPANY SHARES

                  1.1. PURCHASE OF COMPANY SHARES.

                  Subject to the provisions of this Agreement, Parent agrees to
sell, and Buyer agrees to purchase, at the Closing, all the Company Shares for
an aggregate purchase price of the Buyer Shares plus $36,000,000 in cash,
subject to adjustment as provided in Section 1.2 hereof (collectively, the
"PURCHASE PRICE"), which Company Shares constitute, and will constitute at the
Closing, one hundred percent (100%) of the issued and outstanding capital stock
of the Company. The Purchase Price (as such amount may be adjusted as provided
in said Section 1.2), shall be paid by Buyer at the Closing as follows:

                    (1) $35,500,000 in cash to Parent at the Closing;

                    (2) the Buyer Shares; and

                    (3) the remaining portion of the Purchase Price (the
                    "HOLDBACK") shall be paid when, if and as provided in
                    accordance with the adjustment set forth in Section 1.2
                    hereof.

                  1.2. DETERMINATION OF CLOSING NET BOOK VALUE; ADJUSTMENT OF
THE PURCHASE PRICE.

                       (a) Not later than forty-five (45) days after the Closing
Date, Parent shall prepare, at Parent's cost, and deliver to the Buyer (i) a
balance sheet of Company as of the Closing Date which will include, among other
things, a detailed statement of the inter-company account obligations to be
settled post Closing (the "CLOSING BALANCE SHEET") and (ii) a statement (the
"CLOSING STATEMENT") indicating the difference between the aggregate book value
of all the assets appearing on the Closing Balance Sheet and the aggregate book
value of all liabilities appearing thereon (the "CLOSING NET BOOK VALUE"). The
Closing Balance Sheet shall be audited by PricewaterhouseCoopers, LLP ("PWC")
(Seattle/Boise offices). The Closing Balance Sheet shall be prepared in
accordance with GAAP and shall fairly present the assets, liabilities and
Closing Net Book Value of Company on the Closing Date. One hundred percent of
the inventory shall be counted on a mutually agreed upon date that is on or
within five (5) business days of the Closing Date at which all parties or their
representatives may be present to observe. Parent will adjust any asset or
liability in any category on the Closing Balance Sheet identified as a result of
such audit in excess of $15,000, whether or not such asset or liability might be
material as defined under GAAP. The value of patents being transferred from
Parent to the Company pursuant to the Patent Assignment and License Agreement in
the form of Exhibit E hereto will not be included at a value higher on the
Closing Balance Sheet than the amount for patents in the Base Balance Sheet. The
cash on the Closing Balance Sheet shall equal or exceed all liabilities on the
Closing Balance Sheet relating to customer prepayments and deferred revenues
that have been collected. Notwithstanding the foregoing, the same accounting
principles, practices, procedures and policies that were used in preparing the
Base Balance Sheet shall be used in preparing the Closing Balance Sheet and the
calculation of Closing Net Book Value, including, in particular, inventory
reserves, warranty accruals, accounts receivable reserves, Parent allocations,
and revenue recognition, even if they may differ from GAAP. The Closing Balance
Sheet will not reflect any income or gain, or associated Tax liability, with
respect to, the Section 338(h)(10) Election. The Closing Balance Sheet shall
also be accompanied by all necessary and appropriate supporting work papers and
materials. If these supporting work papers and materials are materially
deficient or incomplete, the Review Period referenced in Section 1.2(b) hereof
shall not commence until such materials are made complete to give Buyer's
accountants sufficient time to complete their audit of the Closing Balance
Sheet. To the extent that the Closing Net Book Value differs from the comparable
net book value as derived from the Base Balance Sheet (the "BASE NET BOOK
VALUE"), then the Purchase Price shall be adjusted up or down on a dollar for
dollar basis by the amount of such difference as hereinafter set forth. The Base
Net Book Value equals $6,436,167.

                       (b) Following receipt of the Closing Balance Sheet and
supporting work papers and materials, Buyer and Buyer's accountants (PWC, Boston
office) will be afforded a period of forty-five (45) calendar days (the "REVIEW
PERIOD") to audit, at Buyer's cost, the Closing Balance Sheet. During such
Review Period, Buyer and Buyer's accountants will be afforded reasonable access
to any of Parent's employees involved in the preparation of the Closing Balance
Sheet and the records, work papers, trial balances and similar materials
prepared by Parent, Company or their accountants in connection with the
preparation of the audit

and certification of the Closing Balance Sheet; provided, however, that Buyer
shall provide reasonable prior notice of any such investigation to Parent so as
not to unduly interfere with the operations of Parent. At or before the end of
the Review Period, Buyer will either (i) accept the Closing Balance Sheet and
the Closing Statement in their entirety, in which case the Closing Net Book
Value will be deemed to be as set forth on the Closing Statement, and the
Closing Balance Sheet and the Closing Statement shall become final, binding and
conclusive on the Parties, or (ii) deliver to Parent and Parent's accountants a
written notice in accordance with paragraph (d) of this Section 1.2 disputing
the Closing Balance Sheet or the Closing Statement.

                       (c) Within ten (10) days following the later of (x) the
date of the Closing Balance Sheet and the Closing Statement is accepted by Buyer
or (y) the final, binding and conclusive determination of any dispute with
respect to the Closing Balance Sheet or the Closing Statement as provided in
paragraph (d) of this Section 1.2:

                                    (1) if the Closing Net Book Value is less
                                    than the Base Net Book Value and such
                                    difference is less than or equal to
                                    $500,000, then Buyer shall pay to Parent
                                    cash in an amount equal to (i) the Holdback
                                    minus (ii) such difference;

                                    (2) if the Closing Net Book Value is less
                                    than the Base Net Book Value and such
                                    difference is greater than $500,000, then
                                    Parent shall pay to Buyer cash in an amount
                                    equal to (i) the Base Net Book Value minus
                                    (ii) the Closing Book Value minus (iii) the
                                    Holdback;

                                    (3) if the Closing Net Book Value is greater
                                    than the Base Net Book Value, then Buyer
                                    shall pay to Parent cash in an amount equal
                                    to the sum of (i) the Holdback plus (ii)
                                    such difference; and

                                    (4) if the Closing Net Book Value and the
                                    Base Net Book Value are equal, then Buyer
                                    shall pay to Parent cash in an amount equal
                                    to the Holdback.

                       (d) At the same time that payment is made under paragraph
(c), the appropriate party will pay to the other party the net amount owed by
Parent to Company or by Company to Parent with respect to inter-company
payments, including accrued taxes payable to Parent with respect to Tax
liability not previously paid directly to a taxing authority by the Company, but
not Tax liability arising from the Section 338(h)(10) election.

                       (e) In the event that any dispute shall arise as to the
manner of preparation or the accuracy of the Closing Balance Sheet or Closing
Statement prior to the expiration of the Review Period, Buyer shall provide
Parent with written notice of each disputed item. In the event of such a
dispute, Buyer and Parent shall attempt in good faith to reconcile their
differences as to such items within twenty (20) calendar days (the "RESOLUTION
PERIOD") of Parent's receipt of such notice, and any resolution by them as to
any disputed items shall be final, binding and conclusive on Parent and Buyer.
If Buyer and Parent are unable to reach a

resolution with such effect within the Resolution Period, Buyer and Parent shall
submit the dispute to the Phoenix, Arizona office of Deloitte & Touche (the
"INDEPENDENT CPA"). The determination of such dispute by the Independent CPA
shall be final, binding and conclusive on the Parties. The fees and expenses of
the Independent CPA shall be assessed by the Independent CPA fifty percent (50%)
against the Parent and fifty percent (50%) against Buyer, and shall be paid by
each of them in those proportions.

                  1.3. TAXES.

                  Parent shall be solely responsible for all Taxes required by
any Governmental Authority in any relevant jurisdiction which arise out of or
result from the sale of the Company Shares.

                  4.5. INVESTMENT INTENT.

required to be filed by Buyer with the SEC since October 1, 2000, other than any

and each of its subsidiaries as of the respective date thereof and for the

                  Parent, Company and Buyer covenant and agree with one another
as follows:


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

                                       26
   31

                  5.1. FINANCIAL STATEMENTS.

                  Parent shall have delivered to Buyer within ten (10) days of
the Closing the Financial Statements and the Interim Financial Statements and
any other financial information with respect to Company which would be required
in order for Buyer to prepare the pro forma financial information for the
periods since October 1, 1998.

                  5.2. NO IMPLIED REPRESENTATIONS OR WARRANTIES.

                  Buyer hereby acknowledges and agrees that Parent and Company
are not making any representation or warranty whatsoever, express or implied,
except those representations and warranties of Parent and Company explicitly set
forth in this Agreement or in the Disclosure Schedule or in any certificate
contemplated hereby and delivered by Company in connection herewith.

                  5.3. EMPLOYEE BENEFITS.

                  Company shall retain after the Closing the obligation and
responsibility to provide COBRA continuation coverage to any former employees of
Company who are receiving COBRA continuation coverage as of the Closing Date.

                  5.4. SECTION 338(h)(10) ELECTION.

                  At Buyer's election, Parent will join with Buyer in making an
election under section 338(h)(10) of the Internal Revenue Code of 1986, as
amended (and any corresponding elections under state, local, or foreign Tax law)
(collectively, the "SECTION 338(H)(10) ELECTION") with respect to the purchase
and sale of the Company Shares hereunder. Parent will pay any Tax attributable
to the making of the Section 338(h)(10) Election and will indemnify Buyer,
Company, and their affiliates against any penalty, interest or Tax resulting
from an Internal Revenue Service or State taxing authority disallowance, in
whole or in part, of a step-up in basis arising out of any failure of Parent to
file such forms as are provided by Buyer or pay such Tax. In the event Buyer
elects to have a Section 338(h)(10) Election made, Buyer shall prepare Internal
Revenue Service Form 8023 and any similar state, local, and foreign forms, and
shall furnish such forms to Parent. If any additions or changes are required to
these forms as a result of information that is first available after the Closing
Date, Buyer shall prepare amended or supplemental forms, which Buyer shall
furnish to Parent. Each of Parent and Buyer shall timely comply with all
applicable filing requirements with respect to all such forms, including the
attachment of Form 8023 (and any similar forms) to their respective applicable
Returns. Parent and Company each agree to prepare and file their Returns
consistently with Form 8023 as prepared by Buyer.

                  5.5. TAX MATTERS

                       (a) PREPARATION OF RETURNS. Parent shall file or cause to
be filed when due all Returns that are required to be filed by or with respect
to Company on or prior to the Closing Date. Buyer shall file or cause to be
filed when due all Returns that are required to be


- --------------------------------------------------------------------------------
EXECUTION COPY

                                       27
   32

filed by or with respect to Company for periods subsequent to the Closing Date.
With respect to any Taxable period ending on or prior to the Closing Date for
which a Return is required to be filed after the Closing Date, Parent shall
prepare all such pro-forma Returns of Company and shall provide to Buyer, at
least thirty (30) business days prior to the due date, including any extensions,
for the filing thereof, such pro-forma Returns for Company as they will be
included in Parent's consolidated Returns, together with such Tax information
material relevant to such Returns, including schedules and work papers.
Following receipt of any pro-forma Returns prepared by Parent, if Buyer disputes
any of the information contained in such pro-forma Returns, Buyer shall promptly
notify Parent. The Parties shall cooperate to resolve promptly any such dispute
and Parent shall be responsible for their respective professional fees and
expenses incurred in connection therewith. In the event that the Parties are not
able to promptly resolve any such dispute, the dispute shall be resolved by the
following procedures: Buyer and Parent shall settle such dispute by retaining
the Independent CPA to resolve such dispute. The determination of the
Independent CPA will be set forth in writing and shall be issued within
forty-five (45) days of the date the Independent CPA is retained except that if
the due date for filing the Return after all extensions of right shall expire
before such date, the determination shall be made not later than the second
business day before the filing date. Any decision by the Independent CPA shall
be final and binding upon the parties, absent fraud or manifest error, and
judgment may be entered thereon, upon the application of either party, by any
court having competent jurisdiction. Each Party shall bear the cost of preparing
and presenting its case; and the fees and expenses of the Independent CPA will
be shared equally by Buyer and Parent.

                       (b) ASSISTANCE AND COOPERATION. After the Closing Date,
each of Parent and Buyer shall:

                                    (1) assist (and cause their respective
                  affiliates and subsidiaries to assist) the other Party in
                  preparing Returns that such other Party is responsible for
                  preparing and filing;

                                    (2) cooperate fully in preparing for any
                  audits of, or disputes with Tax authorities regarding, any
                  Returns of Company;

                                    (3) make available to the other as
                  reasonably requested all information, records and documents
                  relating to Taxes of Company;

                                    (4) provide timely notice to the other in
                  writing of any pending or threatened Tax audits or assessments
                  of Company for Taxable periods for which the other may have a
                  liability under this Agreement; and

                                    (5) furnish the other with copies of all
                  correspondence received from any Tax authority in connection
                  with any Tax audit or information request with respect to any
                  such Taxable period.

                       (c) TRANSFER TAXES. Parent shall be liable for, and shall
timely pay, any and all gains, transfer, sales, use, recording, registration,
documentary, stamp, and other Taxes that may result from, or be incurred in
connection with, this Agreement. Parent shall, at


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

                                       28
   33

its own expense, properly complete, sign, and timely file any and all required
Returns with respect to such Taxes ("TRANSFER TAX RETURNS") and, if required by
applicable law, Buyer and Company will join in the execution of any such
Transfer Tax Returns.

LIABILITY FOR TAXES AND RELATED MATTERS. Parent shall close the Taxable period
of Company as of the close of business on the Closing Date, unless such action
is prohibited by law. In any case where applicable law prohibits Company from
closing its Taxable year on the Closing Date then, for purposes of this Section
5.5(d), the determination of the Taxes of Company for the portion of the year or
period ending on, and the portion of the year or period beginning after, the
Closing Date shall be determined on the basis of an interim closing of the books
as of the close of business on the Closing Date, except that exemptions,
allowances or deductions that are calculated on an annual basis, such as the
deduction for depreciation, shall be ratably apportioned on a time basis (with
proper adjustment for additions or reductions of assets).


                                   ARTICLE 6.

                                  REGISTRATION

                  6.1. REGISTRATION.

                  Buyer shall use its best efforts to file with the Securities
and Exchange Commission ("SEC"), within 15 days after the Closing Date but in no
event more than 30 calendar days after the Closing Date, a registration
statement on Form S-3 (the "REGISTRATION STATEMENT") (or any successor short
form registration involving a similar amount of disclosure; or if then
ineligible to use any such form, then any other available form of registration
statement) for a public offering of all the Buyer Shares to be made on a
continuous basis pursuant to Rule 415 of the Securities Act and will use its
commercially reasonable efforts to cause such registration statement to become
effective (subject to review of such Registration Statement by the SEC) and
remain continuously effective until the Buyer Shares are eligible for sale
pursuant to Rule 144 promulgated under the Securities Act. Buyer may, upon
written notice to Parent, suspend use of the Registration Statement for a
reasonable period if Buyer in its reasonable judgment believes it may possess
material nonpublic information the disclosure of which at that point in time in
its reasonable judgment would have a material adverse effect on Buyer and its
subsidiaries taken as a whole.

                  6.2. COOPERATION.

                  Parent covenants and agrees that it shall provide to Buyer on
a timely basis such consents, representations and information and execute such
documents as may reasonably be required by Buyer in connection with such
Registration Statement.

                  6.3. EXPENSES.

                  Buyer shall pay all expenses of registration of the Buyer
Shares pursuant to Section 6.1, except brokerage and underwriting commissions,
Parent's legal and other advisory expenses and such other expenses as may be
required by law to be paid by Parent.

                  6.4. BUYER INDEMNITY.

                  To the extent permitted by law, Buyer will indemnify and hold
harmless each of Parent, its officers and directors and each person, if any, who
controls Parent within the meaning of the Securities Act, against any costs or
expenses (including attorney's fees), judgments, fines, losses, claims, damages,
liabilities or amounts paid in settlement, joint or several, to which any of
them may become subject under the Securities Act or otherwise, insofar as such
costs or expenses (including attorney's fees), judgments, fines, losses, claims,
damages liabilities or amounts paid in settlement (or actions in respect
thereof) arise out of or are based upon any untrue or alleged untrue statement
of any material fact contained or expressly incorporated by reference in any
such Registration Statement, including any preliminary prospectus or final
prospectus contained therein or any amendment or supplement thereto, or arise
out of or are based upon the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse Parent and its officers and directors
and each such controlling person for any legal or other expenses reasonably
incurred by any of them in connection with investigating or defending any such
loss, claim, damage, liability or action; provided, however, that the indemnity
agreement contained in this Section 6.4 shall not apply to amounts paid in
settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of Buyer (which consent shall not be
unreasonably withheld) nor shall Buyer be liable in any such case for any such
loss, claim, damage, liability or action to the extent that it arises out of or
is based upon an untrue statement or alleged untrue statement or omission or
alleged omission made in connection with such Registration Statement,
preliminary prospectus, final prospectus or amendment or supplement thereto in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by Parent or any person controlling
Parent.

                  6.5. PARENT INDEMNITY.

                  To the extent permitted by law, Parent will indemnify and hold
harmless Buyer, its directors, its officers who have signed such Registration
Statement and each person, if any, who controls Buyer within the meaning of the
Securities Act against any losses, claims, damages or liabilities to which Buyer
or any such director, officer or controlling person may become subject, under
the Securities Act or otherwise, insofar as such losses, claims, damages or
liabilities (or actions in respect thereto) arise out of or are based upon any
untrue or alleged untrue statement of any material fact contained or expressly
incorporated by reference in such Registration Statement, including any
preliminary prospectus or final prospectus contained therein or any amendment or
supplement thereto, or arise out of or based upon the omission or alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent, that such untrue statement or alleged untrue
statement or omission or alleged omission was made in such Registration
Statement, preliminary prospectus, final prospectus or amendments or supplements
thereto, in reliance upon and in conformity with written information furnished
by Parent expressly for use in connection with such registration; and Parent
will reimburse any legal or other expenses reasonably incurred by Buyer or any
such director, officer and controlling person in connection with investigating
or defending any such loss, claim, damage, liability or action. It

is agreed that the indemnity agreement contained in this Section 6.5 shall not
apply to amounts paid in settlement of any such loss, claim, damage, liability
or action if such settlement is effected without the consent of the indemnifying
party (which consent shall not be unreasonably withheld).

                  6.6. CONTRIBUTION.

                  If the indemnification provided for in Sections 6.4 and 6.5
hereof is unavailable to a Person entitled to indemnification hereunder, then
each Person that would have been an indemnifying party hereunder will, in lieu
of indemnifying such indemnified party, contribute to the amount paid or payable
by such indemnified person for which indemnification is provided herein in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party and such indemnified party, respectively, in connection with the
statements or omissions which resulted in the costs or expenses (including
attorney's fees), judgments, fines, losses, claims, damages, liabilities or
amounts paid in settlement underlying such indemnification obligations. Relative
fault will be determined by reference to, among other things, whether the untrue
or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the
indemnifying party or such indemnified party and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. Buyer and Parent agree that it would not be just and
equitable if contribution pursuant to this Section 6.6 were determined by pro
rata allocation or by any other method of allocation that does not take account
of the equitable considerations referred to above in this Section 6.6. No Person
guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of
the Securities Act) will be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation.

                  6.7. NOTICE.

                  Promptly after receipt by a party indemnified under this
Article 6 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against any indemnifying party
under this Article 6, notify the indemnifying party in writing of the
commencement thereof and the indemnifying party shall have the right to
participate in, and, to the extent the indemnifying party desires, jointly with
any other indemnifying party similarly noticed, to assume the defense thereof
with counsel mutually satisfactory to the parties; provided, however that if the
defendants in any such action include both the indemnified party and the
indemnifying party and, under applicable standards of professional conduct, a
conflict on any significant issue between the positions of the indemnified party
and the indemnifying party exists, the indemnified party or parties shall have
the right to select one separate law firm, at the indemnifying party's or
parties' expense, to assume such legal defenses and to otherwise participate in
the defense of such action on behalf of such indemnified party or parties. The
failure to notify any indemnifying party promptly of the commencement of any
such action, shall not relieve such indemnifying party of any liability to the
indemnified party under this Article 6, except to the extent that such
indemnifying party is actually prejudiced thereby.

                       (a) Parent will have no liability with respect to the
matters described in Section 8.2(a) and (f) (insofar as a claim under clause (f)

included in clauses (a)-(c)) of $2,750,000.

                  8.6. PROCEDURE FOR INDEMNIFICATION - THIRD PARTY CLAIMS.

                       (a) Promptly after receipt by an Indemnified Person under
Sections 8.2 or 8.3 of notice of the commencement of any Proceeding against it,
such Indemnified Person will, if a claim is to be made against an Indemnified
Person under such Section, give notice to the indemnifying party of the
commencement of such claim, but the failure to notify the Indemnified Person
will not relieve the indemnifying party of any liability that it may have to any
Indemnified Person, except to the extent that the indemnifying party
demonstrates that the defense of such action is prejudiced by the Indemnified
Person's failure to give such notice.

                       (b) If any Proceeding referred to in Section 8.6(a) is
brought against an Indemnified Person and it gives notice to the indemnifying
party of the commencement of such Proceeding, the indemnifying party will be
entitled to participate in such Proceeding and, to the extent that it wishes
(unless (i) the indemnifying party is also a party to such Proceeding and the
Indemnified Person determines in good faith that joint representation would be
inappropriate, or (ii) the indemnifying party fails to provide reasonable
assurance to the Indemnified Person of its financial capacity to defend such
Proceeding and provide indemnification with respect to such Proceeding), to
assume the defense of such Proceeding with counsel satisfactory to the
Indemnified Person and, after notice from the indemnifying party to the
Indemnified Person of its election to assume the defense of such Proceeding, the
indemnifying party will not, as long as it diligently conducts such defense, be
liable to the Indemnified Person under this Section 8 for any fees of other
counsel or any other expenses with respect to the defense of such Proceeding, in
each case subsequently incurred by the Indemnified Person's in connection with
the defense of such Proceeding, other than reasonable costs of investigation. If
the indemnifying party assumes the defense of a Proceeding, (i) it will be
conclusively established for purposes of this Agreement


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

                                       34

that the claims made in that Proceeding are within the scope of and subject to
indemnification; (ii) no compromise or settlement of such claims may be effected
by the indemnifying party without the Indemnified Person's consent unless (A)
there is no finding or admission of any violation of Law or any violation of the
rights of any person and no effect on any other claims that may be made against
the Indemnified Person, and (B) the sole relief provided is monetary damages
that are paid in full by the indemnifying party; and (iii) the Indemnified
Person will have no liability with respect to any compromise or settlement of
such claims effected without its consent. If notice is given to an indemnifying
party of the commencement of any Proceeding and the indemnifying party does not,
within ten (10) days after the Indemnified Person's notice is given, give notice
to the Indemnified Person of its election to assume the defense of such
Proceeding, the indemnifying party will be bound by any determination made in
such Proceeding or any compromise or settlement effected by the Indemnified
Person.

                       (c) Notwithstanding the foregoing, if an Indemnified
Person determines in good faith that there is a reasonable probability that a
Proceeding may adversely affect it or its affiliates other than as a result of
monetary damages for which it would be entitled to indemnification under this
Agreement, the Indemnified Person may, by notice to the indemnifying party,
assume the exclusive right to defend, compromise or settle such Proceeding, but
the indemnifying party will not be bound by any determination of a Proceeding so
defended or any compromise or settlement effected without its consent (which may
not be unreasonably withheld).

                  8.7. PROCEDURE FOR INDEMNIFICATION - OTHER CLAIMS.

                  A claim for indemnification for any matter not involving a
third-party claim may be asserted by notice to the party from whom
indemnification is sought.

                  8.8. COSTS; DAMAGES; EXCLUSIVITY.

                       (a) If any legal action or other Proceeding is brought
for the enforcement or interpretation of any of the rights or provisions of this
Agreement, or because of an alleged dispute, breach, default or
misrepresentation in connection with any of the provisions of this Agreement,
the successful or prevailing party shall be entitled to recover reasonable
attorneys' fees and all other costs and expenses incurred in that action or
Proceeding, in addition to any other relief to which it may be entitled.

                       (b) In calculating the amount of Damages under Sections
8.2 and 8.3, such Damages shall be reduced by any tax benefits, insurance
proceeds or payments from any other parties that Buyer receives as a result of
the loss, liability, claim, damage or expense.

                       (c) The Parties acknowledge and agree that the sole
remedies of the Buyer Indemnified Persons against Parent and of the Parent
Indemnified Persons against Buyer for any matter arising out of the transaction
are set forth in this Article 8, and that except to the extent an Indemnified
Person has asserted a claim within the periods provided in Section 8.4, the
Indemnified Person shall have no remedy against the indemnifying party for
breach of any provision of this Agreement.

                  The rights and remedies of the Parties to this Agreement are
cumulative and not alternative. Neither the failure nor any delay by any Party
in exercising any right, power or privilege under this Agreement or the
documents referred to in this Agreement will operate as a waiver of such right,
power or privilege, and no single or partial exercise of such right, power or

privilege or the exercise of any other right, power or privilege. To the maximum
extent permitted by applicable law, (a) no claim or right arising out of this
Agreement or the documents referred to in this Agreement can be discharged by
one Party, in whole or in part, by a waiver or renunciation of the claim or
right unless in writing signed by the other Party; (b) no waiver that may be
given by a Party will be applicable except in the specific instance for which it
is given; and (c) no notice to or demand on one Party will be deemed to be a
waiver of any obligation of such Party or of the right of the Party giving such
notice or demand to take further action without notice or demand as provided in
this Agreement or the documents referred to in this Agreement.
