the aggregate amount of Disputed Items unsuccessfully claimed by such party

amount of the difference. If the amount of Closing Working Capital is less than
Estimated Working Capital, Seller shall promptly pay to (or as directed by)
Purchaser the amount of the difference. Any such payment pursuant to this clause
(v) shall be made within 10 days after (A) Purchaser and Seller agree upon the

referred to a Selected Accounting Firm pursuant to clause (iii), the delivery of
the report of such firm referred to in clause (iii).

         (vi) Any payments pursuant to this Section 2.2(d) shall be made by wire
transfer of immediately available funds to such account of Purchaser or Seller,

at a price equal to 100% of the face value thereof adjusted for any discount PRO
RATA to the Closing Date. Payment of such purchase price shall be made directly
to J.M. Huber Finance Corporation on the Closing Date, and such payment
obligation shall be separate and distinct from Purchaser's obligation to pay
Seller the Closing Cash Consideration. (The price paid for such receivables
shall not be taken into consideration for purposes of calculating Closing
Working Capital under Section 2.2(d)).

         (c) Purchaser and Seller shall use their best efforts to cancel, as of
the Closing, all guarantees, letters of credit or other similar arrangements
("GUARANTEES") entered into by Seller or its Affiliates (other than any of the
AVEX Group) relating to any of the AVEX Group, including the Guarantees listed

Plan (or, in the case of any unwritten Employee Benefit Plans, descriptions

benefits to Former Employees of the AVEX Group other than (i) as necessary to

Plan. To the extent that such AVEX Benefit Plan provides health or other welfare
benefits to Former Employees of the AVEX Group, such obligations are properly
accrued for under GAAP on an ongoing basis by members of the AVEX Group.

      (c) Except as set forth on SCHEDULE 3.13(C), each AVEX Benefit Plan has

which is intended to be qualified under Section 401(a) of the Code has been the
subject of a determination letter from the Internal Revenue Service to the
effect that such AVEX Benefit Plans are qualified and exempt from United States
Federal income taxes under Sections 401(a) and 501(a), respectively, of the

have been properly accrued to the extent required by GAAP, and (iii) none of
Seller nor any of the AVEX Group has incurred any accumulated funding deficiency
(as defined in Section 412 of the Code and Section 302 of ERISA). With respect
to any AVEX Benefit Plan subject to Title IV of ERISA, Seller and the AVEX Group

have a Material Adverse Effect. Except as set forth on SCHEDULE 3.13(D), no
termination or partial termination of any existing AVEX Benefit Plan has
occurred within the last three years, nor has a notice of intent to terminate
any existing AVEX Benefit Plan which is an Employee Pension Benefit Plan been
issued by a member of the AVEX Group. The PBGC has not instituted any
proceedings to terminate any AVEX Benefit Plan. SCHEDULE 3.13(D) sets forth the
unfunded accrued liabilities for each AVEX Benefit Plan that is a "defined
benefit plan," as defined in Section 3(35) of ERISA, which is contained in the
most recently issued valuation actuarial report for each such plan determined on
an ongoing basis and used in calculating the minimum funding requirements under
ERISA. There has been no "reportable event," as defined in Section 4043 of
ERISA, with respect to any AVEX Benefit Plan, for which notice has not been
waived.

      (e) Except as set forth on SCHEDULE 3.13(E), no AVEX Benefit Plan is
funded by a trust described in Section 501(c)(9) of the Code.

                                      -20-

      (f) To the extent that any of the foregoing representations in this
Section 3.13 relate to a AVEX Benefit Plan currently maintained or contributed
to for the benefit of AVEX Employees employed in foreign jurisdictions, such

that are in full force and effect and enforceable by AVEX, Kilbride Holdings or
the relevant Subsidiary of either, as the case may be, in accordance with their
respective terms, except where any lack of enforceability, individually or in
the aggregate would not have or result in a Material Adverse Effect. Seller has
previously provided or made available to Purchaser complete and correct copies

contemplated by this Agreement, each member of the AVEX Group will own or lease,
all tangible personal property required to conduct its business, in all material
respects, in the ordinary and usual course of business and as conducted on the
Closing Date. The machinery and equipment material to the business or operations
of each member of the AVEX Group are in normal operating condition, ordinary
wear and tear and obsolescence excepted, free from any known defects except such
minor defects as do not substantially interfere with the continued use thereof
in the conduct of normal operations. Each member of the AVEX Group has good
title to all its owned tangible personal property, free and clear of all Liens

aggregate, do not materially interfere with the use of such property.

      Section 3.22 ABSENCE OF CERTAIN COMMERCIAL PRACTICES. To the knowledge of
Seller, no member of the AVEX Group, or any of their respective directors or
officers, and none of the agents, affiliates, or employees, or other persons
acting on behalf of any member of the AVEX Group or any of their respective
directors, officers, agents, affiliates or employees, has (i) given, proposed to
give, or agreed to give any material gift or similar benefit to any governmental
employee or official for the purpose of directly or indirectly furthering the
business of any member of the AVEX Group, and which, if not continued in the
future, could reasonably be expected to have a Material Adverse Effect, or (ii)
used any Huber Group funds for contributions, payments, gifts to, or
entertainment of, government officials, or made any expenditures relating to
political activities in violation of any applicable laws, or established or
maintained any unlawful funds.

      Section 3.23 YEAR 2000 MATTERS. The AVEX Group has (i) initiated a review
and assessment of all areas within its business and operations that could be
adversely affected by the "YEAR 2000 PROBLEM" (that is, the risk that computer
applications used by the AVEX Group may be unable to recognize and perform
properly date sensitive functions involving certain dates prior to and at any
date after December 31, 1999), (ii) developed a plan and timeline for addressing
the Year 2000 Problem on a timely basis, and (iii) to

                                      -24-

date, initiated implementation of that plan. Based on the foregoing, and
provided the plan and timeline for addressing the Year 2000 Problem continue to
be implemented and developed on a timely basis by Purchaser after the Closing,
Seller believes that all computer applications that are material to the AVEX
Group's business and operations are reasonably expected on a timely basis to be
able to perform properly date-sensitive functions for all dates before and after
January 1, 2000 (that is, be "Year 2000 Compliant"), except to the extent that a
failure to do so could not reasonably be expected to have a Material Adverse
Effect. The foregoing statements constitute a YEAR 2000 READINESS DISCLOSURE.

      Section 3.24 INVENTORIES AND RECEIVABLES. The inventory of each member of
the AVEX Group as of December 31, 1998 and at May 31, 1999 is reflected in the

ordinary course of business, (ii) to the knowledge of Seller and subject to the
reserves provided for therein, the booked inventory of the AVEX Group consists
in all material respects of items of a quality salable or usable in the ordinary
course of business (except to the extent returnable to the vendors thereof for
the full purchase price), (iii) no member of the AVEX Group is bound by any
inventory purchase commitment, whether oral or written, formal or informal, that
is not cancelable by such member without penalty on written notice of 60 days or
less, or which was not ordered in connection with a valid purchase order, letter
of intent, instruction, forecast or manufacturing agreement from a customer, and
(iv) subject to normal reserves in accordance with past practice not exceeding
the amounts of such reserves in the AVEX Financial Statements, the accounts
receivable of the AVEX Group are, and as of the Closing Time will be, valid and
are subject to no counterclaim, set-off or other deduction or notice of refusal
to pay (other than those arising from standard procedures and contractual
provisions relating to the retest, repair and replacement of customer returns).

      Section 3.25 WARRANTY CLAIMS. Seller has made available to Purchaser
correct and complete copies of all product warranties issued or made by any
member of the AVEX Group in connection with the sale or lease of any product or
the rendition of any service. Seller has made available to Purchaser
descriptions of its standard procedures with regard to the retest, repair and
replacement of customer returns. All existing material warranty, product
liability and similar claims have been properly accrued for or reserved for in
accordance with GAAP in the AVEX Financial Statements and in the Interim
Financial Schedules.

      Section 3.26 RELATIONS WITH CUSTOMERS AND SUPPLIERS. Except as disclosed
in SCHEDULE 3.26, to the knowledge of Seller (i) neither the public announcement
nor consummation of the transactions contemplated hereby will cause any customer
or supplier to terminate its business relationship with any member of the AVEX
Group, and (ii) since December 31, 1998, none of the AVEX Group has received
written notice from

                                      -25-

any of its top 15 customers of a demand for renegotiation of the margin or
mark-up or price redetermination of any material business transaction which has
not been resolved.

      Section 3.27  BOOKS AND RECORDS.

      (a) The minute books and stock ledgers of each member of the AVEX Group
that have been made available, or will be made available prior to Closing, to
Purchaser or its representatives constitute all of the minute books and stock
ledgers of the members of the AVEX Group.

      (b) Each member of the AVEX Group makes and keeps financial books, records
and accounts which, in reasonable detail and in all material respects, are
complete and fairly reflect its transactions and dispositions of its assets and
securities and maintains a system of internal accounting controls sufficient to
provide assurances that (i) transactions involving any member of the AVEX Group
are executed in accordance with management's general or specific authorizations;
(ii) transactions are recorded as necessary (A) to permit the preparation of
financial statements for the AVEX Group in conformity with GAAP or any other
criteria applicable to such statements, and (B) to maintain accountability for
assets; (iii) access to the assets of the members of the AVEX Group is permitted
only in accordance with management's general or specific authorizations; and
(iv) the recorded accountability for assets is compared with existing assets at
reasonable intervals and appropriate action is taken with respect to any

that such laws and applicable regulations may prohibit resale or such Benchmark
Stock without registration under such laws unless an applicable examption from
registration is available.

expressly set forth in this Article III, Seller makes no representation or
warranty, express or implied, at law or in equity, in respect of Seller, any of
the AVEX Group or any of their respective assets, liabilities or operations,

franchise taxes, and be entitled to any tax benefits of any losses for federal,
state and local income and franchise tax purposes, for all taxable periods (or
portions thereof) ending on or before the Closing Date, resulting from the
Election.

            (ii) Purchaser shall be responsible for the initial preparation of
all forms and documents required in connection with the Election, and Purchaser
and Seller shall timely file all forms required to be filed to make the
Election. Seller shall timely execute and deliver to Purchaser such documents or
forms as are required by any tax laws to complete the Election.

            (iii) To the extent permitted by state and local laws, the
principles and procedures of this Section 5.4 shall also apply with respect to a
Section 338(h)(10) election or equivalent or comparable provision under state or
local law, including, without limitation, an election under Section 338(g) of
the Code or equivalent or comparable provision under state or local law. Seller
and Purchaser covenant and agree that to the extent that an election similar to
a Section 338(g) or 338(h)(10) election under the Code is optional under any
state or local law, they shall so elect so as to treat the transactions
contemplated herein as a sale of assets for state and local income and franchise
tax purposes.

      (B) TAX PERIODS ENDING ON OR BEFORE THE CLOSING DATE. Purchaser shall
prepare or cause to be prepared and file or cause to be filed all Tax returns
for AVEX, Kilbride Holdings and their Subsidiaries for all periods ending on or
prior to the Closing Date which are filed after the Closing Date other than
income Tax returns with respect to periods for which a consolidated, unitary or
combined income Tax return of Seller will include the operations of AVEX,
Kilbride Holdings and their Subsidiaries. Such Tax returns shall be prepared by
Purchaser in a manner consistent with practices followed in prior years with
respect to similar Tax returns except for changes required by changes in law or
fact. Purchaser shall provide draft copies to Seller at least 30 days prior to
the due date (as extended) for such returns and shall permit Seller to review
and comment on each such Tax return described in the preceding sentence prior to
filing and shall make such revisions to such returns as are reasonably requested
by Seller. Seller shall reimburse Purchaser for Taxes of AVEX, Kilbride Holdings
and their Subsidiaries with respect to such periods within fifteen (15) days
after payment by Purchaser or AVEX, Kilbride Holdings and their Subsidiaries of
such Taxes to the extent such Taxes are not reflected in the Closing Working
Capital.

      (C) TAX PERIODS BEGINNING BEFORE AND ENDING AFTER THE CLOSING DATE.
Purchaser shall prepare or cause to be prepared and file or cause to be filed
any Tax returns of AVEX, Kilbride Holdings and their Subsidiaries for Tax
periods which begin

                                      -31-

before the Closing Date and end after the Closing Date. Such Tax returns shall
be prepared by Purchaser in a manner consistent with practices followed in prior
years with respect to similar Tax returns except for changes required by changes
in law or fact. Purchaser shall provide draft copies to Seller at least 30 days
prior to the due date (as extended) for such returns and permit Seller to review
and comment on each such Tax return described in the preceding sentence prior to
filing and shall make such revisions to such returns as are reasonably requested
by Seller. Seller shall pay to Purchaser within fifteen (15) days after the date
on which approved Taxes are paid with respect to such periods an amount equal to
the portion of such Taxes which relates to the portion of such taxable period
ending on the Closing Date to the extent such Taxes are not reflected in the
Closing Working Capital.

           For purposes of this Section 5.4, in the case of any Taxes that are
imposed on a periodic basis and are payable for a taxable period that includes
(but does not end on) the Closing Date, the portion of such Tax which relates to
the portion of such taxable period ending on the Closing Date shall (x) in the
case of any Taxes other than Taxes based upon or related to income or receipts
(including value-added taxes and similar taxes such as the Goods and Services
Tax imposed by Singapore) be deemed to be the amount of such Tax for the entire
taxable period multiplied by a fraction the numerator of which is the number of
days in the taxable period ending on the Closing Date and the denominator of
which is the number of days in the entire taxable period, and (y) in the case of
any Tax based upon or related to income or receipts (including value-added taxes
and similar taxes such as the Goods and Services Tax imposed by Singapore) be
deemed equal to the amount which would be payable if the relevant taxable period
ended on the Closing Date. Any credits relating to a taxable period that begins
before and ends after the Closing Date shall be taken into account as though the
relevant taxable period ended on the Closing Date. All determinations necessary
to give effect to the foregoing allocations shall be made in a manner consistent
with prior practice of AVEX, Kilbride Holdings and their Subsidiaries.

        (d) REFUNDS AND TAX BENEFITS. Any Tax refunds that are received by
Purchaser or AVEX, Kilbride Holdings and their Subsidiaries and any amounts
credited against Tax to which Purchaser or AVEX, Kilbride Holdings and their
Subsidiaries become entitled, that relate to Tax periods or portions thereof
ending on or before the Closing Date shall be for the account of Seller, and
Purchaser shall pay over to Seller any such refund or the amount of any such
credit within fifteen (15) days after receipt or entitlement thereto. In
addition, to the extent that a claim for refund or a proceeding results in a
payment or credit against Tax by a taxing authority to the Purchaser or AVEX,
Kilbride Holdings and their Subsidiaries, of any amount reflected in the Closing
Working Capital, the Purchaser shall pay such amount to Seller within fifteen
(15) days after receipt or entitlement thereto.

        (e) ALLOCATION OF PURCHASE PRICE. (i) Seller and Purchaser agree (x) in
all circumstances to allocate, within three months following the Closing Date,
the portion of the Purchase Price attributable to the sale of the AVEX Stock
hereunder for U.S. federal income tax purposes pursuant to Treas. Reg. Sec.
1.338(h)(10)-l(f), which agreement as to allocation shall be in writing, and (y)
to follow said Purchase Price allocation for

                                      -32-

purposes of all U.S. federal and, where applicable, state and local income and
franchise tax returns, to the extent said values are relevant for such purposes.
For purposes of this Section 5.4(e), the value of the Benchmark Stock delivered
to Seller pursuant to Section 2.2(c) shall be calculated based upon the average
closing sale price thereof on the Closing Date, or, if the Closing Date is not a
Business Day, on the trading day immediately preceding the Closing Date. In the
event that the parties cannot agree on the proper allocation within the
three-month period described above, the parties will follow the dispute
resolution procedure established in Section 2.2(d) for working capital items by
selecting the Selected Accounting Firm, which will establish the allocation
within one month of the end of the three-month period.

           (ii) Unless they are required to be changed by the final and
non-appealable determination of a taxing authority, the agreements in this
Section 5.4 shall remain in effect for a period of one year past the statute of
limitations governing the duration of either party's rights or liabilities in
any particular instance.

      Section 5.5 COMMERCIAL EFFORTS; FURTHER ASSURANCES. (a) Subject to the
terms and conditions herein provided, each of the parties hereto shall use its
commercially reasonable efforts to take, or cause to be taken, all action, and
to do, or cause to be done, all things reasonably necessary, proper or advisable

transactions contemplated by this Agreement. Seller and Purchaser will use their
commercially reasonable efforts to obtain consents of all Governmental
Authorities and third parties necessary to the consummation of the transactions
contemplated by this Agreement.

      (b) In the event any claim, action, suit, investigation or other
proceeding by any Governmental Authority or other Entity is commenced which
questions the validity or legality of the transactions contemplated hereby or
seeks damages in connection therewith, the parties agree to cooperate and use
commercially reasonable efforts to defend against such claim, action, suit,
investigation or other proceeding and, if an injunction or other order is issued
in any such action, suit or other proceeding, to use commercially reasonable
efforts to have such injunction or other order lifted, and to cooperate
reasonably regarding any other impediment to the consummation of the
transactions contemplated hereby.

      (c) Both before and after the Closing, Seller and Purchaser shall
cooperate to assist each member of the AVEX Group in obtaining any
authorizations, consents and acknowledgments that are required under any
Government Commitment to enable each member of the AVEX Group, to be entitled to
continue to receive all payments to come due after the Closing under such
Government Commitment.

      Section 5.6 AMENDMENTS TO SCHEDULES; NOTICE OF NONCOMPLIANCE. (i) Each of
Seller and Purchaser agrees that it shall, as soon as reasonably practicable
after it learns of the existence of any facts or circumstances causing any of
the representations and warranties herein made or other information contained
herein, respectively, by Seller or Purchaser (including those representations
and warranties contained in Article III or Article IV), to have been incorrect
when made or to have thereafter become incorrect

                                      -33-

this Agreement was signed or the happening thereafter of any event or occurrence
or otherwise), deliver to the other one or more amended Schedules to this
Agreement for the purpose of correcting or updating such representations and
warranties or information; and (ii) each party shall give prompt written notice

complied with or satisfied by it under this Agreement, PROVIDED, that Seller or
Purchaser, as the case may be, shall have 30 days following the giving of a
notice pursuant to this clause (ii) in which to cure or remedy any such failure
to comply with or satisfy any such covenant, condition or agreement, except for
Purchaser's obligation to pay the Purchase Price as specified herein on the
Closing Date.

      Section 5.7 PUBLIC ANNOUNCEMENTS. The timing and content of all
announcements regarding any aspect of this Agreement to the financial community,
any Governmental Authority, employees or the general public shall be mutually
agreed upon in advance by Seller and Purchaser; PROVIDED, that each party hereto
may make any such announcement which it in good faith believes, based on advice
of counsel, is necessary or advisable in connection with any requirement of law
or regulation, it being understood and agreed that each party shall promptly

Group or, following the Closing, Purchaser, to reemploy any employee of the AVEX
Group who is not actively at work on the Closing due to leave of absence,
disability leave, military leave or layoff with recall rights (collectively,
"INACTIVE EMPLOYEES"). For purposes hereof, Active Employees who immediately
following the Closing continue their employment with the AVEX Group and Inactive
Employees, whether or not they become reemployed by the AVEX Group, shall be
referred to herein collectively as "CONTINUED EMPLOYEES." Subject to any
contractual or legal requirements, Purchaser or any member of the AVEX Group
shall have the right to dismiss or terminate any

                                      -34-

as a "FORMER EMPLOYEE."

        (b) SEVERANCE OBLIGATIONS. Seller and Purchaser agree that the
transactions contemplated hereby shall not constitute a severance of employment
of any Continued Employee prior to the consummation of the transactions
contemplated hereby. Pursuant to Section 6.2, Purchaser shall indemnify Seller
from any and all claims made by a Continued Employee or Former Employee for
severance or other separation benefits and from any and all claims based on the

which funds or receipts of any of the AVEX Group are swept into or otherwise
transferred into any bank or other deposit account maintained by or under the
control of Seller are converted to bank or other deposit accounts maintained by
or under the control of Purchaser. If after Closing the funds held in any
accounts of the AVEX Group are swept into accounts under the control of Seller,
Seller agrees to hold any such funds in trust for the AVEX Group and promptly to
return such funds to the AVEX Group, with interest thereon at the prime rate.

5.12(a) are reasonable and necessary for the protection of the Business from and
after the Closing Date, (ii) the breach of Section 5.12(a) by Seller or any of

respect of any Damages, the indemnified party shall promptly, and in any event
within 30 days after the receipt of notice of such claim or demand which may
give rise to a claim under this Article VI, if a claim in respect thereof is to
be made against the indemnifying party hereunder, cause written notice thereof
to be given to the indemnifying party; PROVIDED, HOWEVER, that failure to so
notify the indemnifying party shall not relieve the indemnifying party from any
obligations it may have to the indemnified party hereunder, except to the extent
that it is prejudiced by such failure. In the event any claim or demand for
indemnification is made under this Article VI, the indemnifying party shall be
entitled to meaningfully participate therein and, upon delivery by the
indemnifying party to the indemnified party of written notice, the indemnifying
party may assume and control the defense thereof with counsel of its choice, and
thereafter the indemnifying party shall not be liable to such indemnified party
hereunder for any fees of other counsel subsequently accrued by the indemnified
party in connection with the defense thereof. In the event that any claim or
demand is made under this Article VI, the indemnifying party and the indemnified
party shall cooperate fully with each other in connection with the defense,
negotiation or settlement of any such claim or demand. If the indemnifying party
assumes the defense of an action, (a) the indemnified party shall be entitled to
participate therein at its sole cost and expense and (b) no settlement or
compromise thereof may be effected by the indemnified party without the consent
of the indemnifying party. If the indemnifying party does not assume the defense
of an action, no compromise or settlement thereof may be effected at the expense
of the indemnifying party without the consent of the indemnifying party, which
consent shall not be unreasonably withheld or delayed.

prior to Closing:

        (a)  by written consent of Seller and Purchaser;

reflected therein would result in a material diminution of the value expected to
be derived by it as a result of the transactions contemplated by this Agreement
subject, to the final clause of this Section 8.1(f); PROVIDED, HOWEVER, that
neither Purchaser nor Seller shall have the right to terminate this Agreement

or Purchaser, as the case may be, shall have failed to provide, within five (5)
days of delivery of such notice, assurances against such material diminution in

is given within 5 days before the Closing Date, the Closing Date shall be
extended day for day.

no party shall have any liability to the other party, except as specifically
provided for elsewhere in this Agreement and except that nothing herein will
relieve any party from liability for any willful breach of any representation,
warranty, agreement or covenant contained herein prior to such termination.

instrument in writing signed on behalf of each of the parties hereto, and may

for performance of any of the obligations or other acts of the other parties
hereto may be extended) by the party which is, or the party the shareholders of
which are, entitled to the benefits thereof.

into this Agreement and are hereby made a part hereof as if set out in full in
this Agreement.

      Section 9.3 EXPENSES. Regardless of whether the transactions provided for

party hereto shall pay its own expenses incident to this Agreement and the
transactions contemplated hereby. No expenses of the transaction will be paid by

      Section 9.4 SPECIFIC PERFORMANCE. The parties agree that the AVEX Stock
and Kilbride Holdings Stock constitute unique property that cannot be readily
obtained on the open market. For this reason, Seller agrees that Purchaser would
be irreparably injured if this Agreement is not specifically enforced.
Therefore, Purchaser shall have the right to seek specific performance of this
Agreement, and Seller agrees to waive the defense in any such suit that
Purchaser has an adequate remedy at law and to interpose no opposition, legal or
otherwise, as to the propriety of specific performance as a remedy. Purchaser's
right to seek specific performance shall be in addition to, and not in lieu of,
any other rights or remedies that may be available to it in the event of
Seller's breach or default hereunder of its covenant and agreement to sell the
AVEX Stock and Kilbride Holdings Stock to Purchaser.

      Section 9.5 GOVERNING LAW; CONSENT TO JURISDICTION. This Agreement shall
be governed by, and construed in accordance with, the internal laws of the State
of New York without reference to the choice of law or conflicts of law
principles thereof. Any legal action or proceeding with respect to this
Agreement or any document related hereto may be brought in the courts of the
State of New York or the United States of America located in New York, and, by
execution and delivery of this Agreement, each of Purchaser and Seller hereby
accepts for itself and in respect of its property, generally and
unconditionally, the jurisdiction of the aforesaid courts. The parties hereto
hereby irrevocably waive any objection, including, without limitation any FORUM
NON CONVENIENS, which any of them may now or hereafter have to the bringing of
such action or proceeding in such respective jurisdictions.

      Section 9.6 ASSIGNMENT; SUCCESSORS AND ASSIGNS; NO THIRD PARTY RIGHTS.
Except as otherwise provided herein, this Agreement may not be assigned, and any
attempted assignment shall be null and void. Subject to the foregoing, this
Agreement shall be

                                      -45-

binding upon and inure to the benefit of the parties hereto and their respective
successors, permitted assigns and legal representatives. This Agreement shall be
for the sole benefit of the parties to this Agreement and their respective
successors, permitted assigns and legal representatives and is not intended, nor
shall be construed, to give any Entity, other than the parties hereto and their
respective successors, assigns and legal representatives, any legal or equitable
right, remedy or claim hereunder.

      Section 9.7 AMENDMENTS; WAIVER. No amendment or waiver of any provision of
this Agreement, nor consent to any departure by any party therefrom, shall in
any event be effective unless the same shall be in writing and signed by the
parties hereto. Any waiver or consent shall be effective only in the specific
instance and for the specific purpose for which given.

      Section 9.8 COUNTERPARTS. This Agreement may be executed in counterparts,
any one of which may be by facsimile followed by the originally executed
document forwarded immediately thereafter to the other parties hereto, each of
which shall be deemed an original agreement, but all of which together shall
constitute one and the same instrument.

      Section 9.9 TITLES AND HEADINGS. The titles, captions and table of
contents in this Agreement are for reference purposes only, and shall not in any
way define, limit, extend or describe the scope of this Agreement or otherwise
affect the meaning or interpretation of this Agreement.

      Section 9.10 ENTIRE AGREEMENT. This Agreement, including the Exhibits and
Schedules attached hereto, the Confidentiality Agreement, the Indemnification
Agreement and, upon the execution and delivery thereof, the Registration Rights
Agreement, constitute the entire agreement among the parties with respect to the
matters covered hereby and thereby and supersede all previous written, oral or
implied understandings among them with respect to such matters, except for
Section 3(c) of the Amendment Agreement and except to the extent that other
written agreements are expressly referred to herein.

      Section 9.11 SEVERABILITY. Any term or provision of this Agreement which
is invalid or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such invalidity or unenforceability without
rendering invalid or unenforceable the remaining terms and provisions of this
Agreement or affecting the validity or enforceability of any of the terms or
provisions of this Agreement in any other jurisdiction. If any provision of this
Agreement is so broad as to be unenforceable, such provision shall be
interpreted to be only so broad as is enforceable.

                                      -46-
