Plan  shall  have any right  thereunder  to  acquire  any  capital  stock of any
Acquired Company, the Buyer or any of its Affiliates or any other rights thereto
or interest therein.  At or prior to the Closing,  the Company shall furnish the
Buyer with  evidence of all of the  foregoing in form and  substance  reasonably
satisfactory to the Buyer.

                  (b)      Effective prior to the Closing,  the Company and each

and acknowledgements to effectuate the foregoing,  and (iii) take or cause to be
taken all such  actions as are  required to cause and ensure that from and after
the Closing,  no Warrantholder  (or former  Warrantholder)  shall have any right
thereunder  to acquire any capital stock of any Acquired  Company,  the Buyer or
any of its  Affiliates or any other rights  thereto or interest  therein.  At or
prior to the Closing,  the Company  shall furnish the Buyer with evidence of all
of the foregoing in form and substance reasonably satisfactory to the Buyer.

         1.7      ESCROW CASH. On the Closing  Date,  the Buyer shall deliver to
the  Escrow  Agent  (i)  the  Escrow  Cash  for  the  purpose  of  securing  the
indemnification  obligations of the Selling Securityholders set forth in ARTICLE

of paying the Representative Expenses as set forth in Section 1.8(e). The Escrow
Cash and the  Representative  Escrow Amount shall be held in  segregated  escrow
accounts to be maintained  separately as trust funds and shall not be subject to
any lien,  attachment,  trustee  process  or any other  judicial  process of any
creditor of any Party,  and shall be held and disbursed  solely for the purposes

deliver  the  Escrow  Agreement  and to  perform  their  obligations  thereunder
(including authorizing deliveries to the Buyer of Escrow Cash in satisfaction of
any claims for which the Selling  Securityholders  may be required to  indemnify
the Buyer  pursuant  to ARTICLE  VII hereof and  authorizing  deliveries  of the
Representative  Escrow Amount,  in each case in accordance with the terms of the
Escrow  Agreement),  and  (iv) to  take  any and  all  additional  action  as is
contemplated to be taken by or on behalf of the Selling  Securityholders  by the
terms of this  Agreement,  in each case  without  having  to seek or obtain  the
consent of any Person under any  circumstance.  The Buyer and the Company hereby
waive any conflict of interest that may arise in the appointment of Dr. Chappuis
as  a   Securityholders'   Representative   and  in  the   performance   of  his
responsibilities  in such  capacity  under the terms of this  Agreement  and the
Escrow Agreement.

                  (b)      In the  event  that Dr.  Chappuis  or Mr.  Feuerstein
dies, becomes unable to perform his  responsibilities  hereunder or resigns from
such position, the other  Securityholders'  Representative shall act as the sole
Securityholders' Representative.  In the event that both of Dr. Chappuis and Mr.
Feuerstein  die,  become unable to perform their  responsibilities  hereunder or
resign as Securityholders'  Representatives,  such person or persons selected by
the  Selling  Securityholders  who held a majority  of the  outstanding  Company
Securities  immediately prior to the Closing shall serve as the Securityholders'
Representative(s)   and   shall   be   deemed   to   be   the   Securityholders'
Representative(s) for all purposes of this Agreement.

                  (c)      All  decisions  and  actions by the  Securityholders'
Representatives,   including   any   agreement   between  the   Securityholders'
Representatives  and the Buyer  relating  to the  defense or  settlement  of any
claims for which the Selling  Securityholders  may be required to indemnify  the
Buyer  pursuant to ARTICLE VII hereof,  shall be binding upon all of the Selling
Securityholders  without the Securityholders'  Representatives having to notify,
seek or obtain the consent of any Selling Securityholder under any circumstance,
and no Selling Securityholder shall have the right to object,  dissent,  protest
or otherwise contest the same.

                  (d)      By their  execution  of this  Agreement,  the Selling
Securityholders agree that:

                  (i)      the Buyer shall be able to rely  conclusively  on the
         instructions and decisions of the  Securityholders'  Representatives as
         to  the   determination   of  the   settlement   of  any   claims   for
         indemnification  by any Buyer Indemnified Party pursuant to ARTICLE VII
         hereof, the payment of any Representative  Expenses pursuant to Section
         1.8(e) hereof or any other actions required or permitted to be taken by
         the Securityholders'  Representatives hereunder, and no Party hereunder
         shall   have  any   cause  of   action   against   the   Buyer  or  the
         Securityholders' Representatives for any action taken

                                       5


         by the Buyer in reliance  upon the  instructions  or  decisions  of the
         Securityholders' Representatives;

                  (ii)     all  actions,   decisions  and  instructions  of  the
         Securityholders'  Representatives  shall be conclusive and binding upon
         all of the Selling  Securityholders,  and each  Selling  Securityholder
         hereby  waives  any  and  all  claims   against  the   Securityholders'
         Representatives  and  agrees  that he,  she or it will have no claim or
         cause of action and will not make any claim or take any action  against
         the  Securityholders'  Representatives  for any action taken,  decision
         made or instruction given by the Securityholders' Representatives under
         this Agreement (or any omission thereof under this  Agreement),  except
         for fraud,  willful  misconduct or intentional breach of this Agreement
         by the Securityholders' Representatives;

                  (iii)    the Selling Securityholders shall severally indemnify
         the Securityholders' Representatives and hold them harmless against any
         Damages  incurred  without  fraud,  willful  misconduct or  intentional
         breach  of  this   Agreement  on  the  part  of  the   Securityholders'
         Representatives and arising out of or in connection with the acceptance
         or administration of their duties  hereunder,  including  out-of-pocket
         costs and  expenses  and legal fees and other  legal  costs  reasonably
         incurred by the Securityholders' Representatives;

                  (iv)     the  provisions  of this Section 1.8 are  independent
         and severable,  are  irrevocable and coupled with an interest and shall
         be enforceable  notwithstanding any rights or remedies that any Selling
         Securityholder   may  have  in   connection   with   the   transactions
         contemplated by this Agreement;

                  (v)      remedies  available  at law  for  any  breach  of the
         provisions of this Section 1.8 are  inadequate;  therefore,  the Buyer,
         the Securityholders'  Representatives and the Company shall be entitled
         to temporary and permanent  injunctive  relief without the necessity of
         proving  damages  if any such  Party  brings an action to  enforce  the
         provisions of this Section 1.8; and

                  (vi)     the  provisions  of this Section 1.8 shall be binding
         upon the executors, heirs, legal representatives and successors of each
         Selling  Securityholder,  and any  references  in this  Agreement  to a
         Selling Securityholder or to the Selling Securityholders shall mean and
         include  the   successors  to  the  Selling   Securityholders'   rights
         hereunder,  whether pursuant to testamentary  disposition,  the laws of
         descent and distribution or otherwise.

                  (e)      Each  of  the  Securityholders'  Representatives  may
incur  out-of-pocket  expenses  (including  attorney's  fees and court costs) on
behalf of the Selling  Securityholders  in his  capacity  as a  Securityholders'
Representative (collectively, the "REPRESENTATIVE EXPENSES"). The Representative
Expenses  will  be  paid  solely  out of the  Representative  Escrow  Amount  in
accordance  with  the  Escrow  Agreement.  Upon  the  expiration  of the  Escrow
Agreement  in   accordance   with  its  terms,   any  funds   remaining  in  the
Representative Escrow Amount that shall not have been used to pay Representative
Expenses shall be distributed to the Selling Securityholders  according to their
Pro Rata Share.

                                       6


         1.9      CURRENCY.  All  references  herein to  "Dollars"  and  amounts
preceded by a "$" shall be construed as references to United States dollars.

         1.10     WITHHOLDING.  The  Buyer  shall  be  entitled  to  deduct  and
withhold from the consideration  otherwise payable pursuant to this Agreement to
any Selling  Securityholder  such amounts as the Buyer is required to deduct and
withhold under the Code, or any  provisions of foreign,  state or local Tax Law,
with  respect to the making of such  payment.  To the extent that amounts are so
withheld by the Buyer,  such withheld  amounts shall be treated for all purposes
of this Agreement as having been paid to the Selling Securityholder,  in respect
of whom such deduction and withholding was made by the Buyer.

respect  to  this  Section  3.4(c)(ii),   (A)  any  conflict,  breach,  default,

reflected,  or for which reserves were  established,  on the Most Recent Balance

Liabilities  of any nature that would be required to be  reflected  on a balance
sheet for the Acquired  Companies  prepared in accordance with GAAP or which has
had, or could reasonably be expected to have, a Company Material Adverse Effect.
Other than as set forth in Section 3.5 of the Disclosure  Schedule,  none of the

         3.6      TAX MATTERS.

                  (a)      FILING OF TAX  RETURNS.  Each  Acquired  Company  has
timely filed with the appropriate Governmental Entities all material Tax Returns
required to be filed under any

                                       12


applicable  Laws. All such Tax Returns are complete and accurate in all material
respects.  The Acquired  Companies  are not  currently  the  beneficiary  of any
extension of time within which to file any Tax Return. No written claim has ever
been made by any  Governmental  Entity  in a  jurisdiction  where  any  Acquired
Company  does not file Tax  Returns  that it is or may be subject to taxation by
that jurisdiction.

                  (b)      PAYMENT  OF  TAXES.  All  Taxes  due and owing by the
Acquired Companies and any of their  predecessors or Affiliates  (whether or not
shown on any Tax Returns) have been paid on a timely basis.  All withholding Tax
requirements  imposed on the  Acquired  Companies  for the  period  ending on or
before the Closing Date have been  satisfied in full in all respects or recorded
as a Liability on the Most Recent Financial Statements.  The unpaid Taxes of the
Acquired Companies did not, (i) as of the date of the Most Recent Balance Sheet,
exceed the accruals  and reserve for Tax  Liability  (excluding  any reserve for
deferred Taxes  established to reflect timing  differences  between book and Tax
income) set forth on the face of the Most Recent  Balance  Sheet,  and (ii) will
not exceed that reserve as adjusted for operations and transactions  through the
Closing  Date in  accordance  with past  custom and  practice  of such  Acquired
Companies in filing their Tax Returns.  No liens for Taxes exist with respect to
any assets or properties of any of the Acquired Companies,  except for statutory
liens  for  Taxes  not yet due and  liens  for  Taxes  an  Acquired  Company  is
contesting in good faith through appropriate  proceedings and for which adequate
reserves have been established.

                  (c)      AUDITS, INVESTIGATIONS OR CLAIMS. No deficiencies for
Taxes of the  Acquired  Companies  have been  claimed or proposed or assessed in
writing by any Governmental Entity. There are no pending or, to the knowledge of
the Company or the Selling  Securityholders,  threatened audits,  assessments or
other  actions  for or  relating  to any  Liability  in  respect of Taxes of the
Acquired  Companies  (or their  predecessors  or  Affiliates),  and there are no
matters under  discussion  with any  governmental  authorities,  or known to the
Selling  Securityholders or the Acquired  Companies,  with respect to Taxes that
are likely to result in an  additional  Liability  for Taxes with respect to the
Acquired  Companies  (or their  predecessors  or  Affiliates).  The  Company has
delivered or made  available to Buyer  complete and accurate  copies of foreign,
federal,  state and local Tax  Returns  of the  Acquired  Companies  (and  their
respective  predecessors  and Affiliates) for the years ended December 31, 2003,
2004 and 2005,  and  complete  and  accurate  copies of all audited  examination
reports and  statements  of  deficiencies  assessed  against or agreed to by any
Acquired Company (or its respective  predecessors)  since December 31, 2001. The
U.S.  federal  and state and the  foreign  income Tax  Returns  of the  Acquired
Companies have been audited by the IRS or the prescribed  Governmental Entity in
the relevant  jurisdiction  or are closed by the statute of limitations  for all
taxable  years  through  the  taxable  years  specified  for such Tax Returns in
Section 3.6(c) of the Disclosure Schedule.  The Acquired Companies have not (nor
has any  predecessor or Affiliate)  waived any statute of limitations in respect
of Taxes or agreed to any extension of time with respect to a Tax  assessment or
deficiency,  nor has any request been made in writing for any such  extension or
waiver.  No power  of  attorney  (other  than  powers  of  attorney  authorizing
employees  of the Company to act on behalf of the  Company)  with respect to any
Taxes has been  executed or filed with any Tax  authority or other  Governmental
Entity.

                  (d)      TAX ELECTIONS. All material elections with respect to
Taxes  affecting  any  Acquired  Company are set forth on Section  3.6(d) of the
Disclosure Schedule. No Acquired

                                       13

Section  481(a)  of the Code by  reason  of a change  in  accounting  method  or
otherwise; (ii) has elected at any time to be treated as an S corporation within
the meaning of Sections  1361 or 1362 of the Code;  or (iii) has made any of the

under any comparable state or local Tax provision.

                  (e)      DEFERRED TAX LIABILITIES.  Except as reflected in the
Most  Recent  Financial  Statements  (including  the  schedules  thereto) of the
Acquired Companies,  none of the Acquired Companies shall be required to include
in a taxable  period ending after the Closing  taxable  income  attributable  to
income that accrued (for purposes of their Most Recent Financial  Statements) in
a prior  taxable  period but was not  recognized  for Tax  purposes in any prior
taxable  period  as a  result  of the  installment  method  of  accounting,  the
completed  contract  method of  accounting,  the  long-term  contract  method of
accounting,  the  cash  method  of  accounting  or  Section  481 of the  Code or
comparable provisions of state or local Tax Law, domestic or foreign.

                  (f)      TAX SHARING AND PRE-FILING  AGREEMENTS.  There are no
Tax-sharing, indemnity, allocation, pre-filing, or advance pricing agreements or
similar  arrangements  with respect to or involving any Acquired  Company,  and,
after  the  Closing  Date,  no  Acquired  Company  shall  be  bound  by any such
agreements or similar  arrangements or have any Liability thereunder for amounts
due in respect of periods prior to the Closing Date.

                  (g)      OTHER ENTITY LIABILITY.  No Acquired Company has ever
been a member of an affiliated  group filing a  consolidated  federal income Tax
Return  (other  than a group  the  common  parent of which is the  Company).  No
Acquired Company has any Liability for the Taxes of any Person (other than other
members of the  affiliated  group of which the  Company is the parent) (i) under
Treasury  Regulation Section 1.1502-6 (or any similar provision of state, local,
or foreign law), (ii) as a transferee or successor,  (iii) by contract,  or (iv)
otherwise.

                  (h)      USRPHC.  No  Acquired  Company has ever been a United
State real property holding  corporation within the meaning of Section 897(c)(2)
of the Code during the applicable  period specified in section  897(c)(1)(A)(ii)
of the Code.

                  (i)      PARTNERSHIPS  AND SINGLE  MEMBER LLCS.  Except as set
forth in Section 3.6(i) of the Disclosure Schedule, no Acquired Company (i) is a
partner for Tax purposes  with  respect to any joint  venture,  partnership,  or
other  arrangement  or  contract  which  is  treated  as a  partnership  for Tax
purposes,  or (ii)  owns a single  member  limited  liability  company  which is
treated as a disregarded entity.

                  (j)      DISALLOWANCE  OF  INTEREST  DEDUCTIONS.  None  of the
outstanding indebtedness of the Acquired Companies constitutes indebtedness with
respect to which any interest deductions may be disallowed under Sections 163(i)
or 163(l) or 279 of the Code or under any other provision of applicable Law.

                  (k)      TAX SHELTERS. The Acquired Companies have not entered
into  any  transaction  identified  as a  "reportable  transaction"  or  "listed
transaction"  for  purposes of Code  Section  6707A(c)  or Treasury  Regulations
Sections 1.6011-4(b)(2) or 301.6111-2(b)(2). No

                                       14


Acquired Company has entered into any transaction that, if the treatment claimed
by it were to be  disallowed,  the  transaction  would  result in a  substantial
understatement of federal income Tax within the meaning of Code Section 6662.

                  (l)      SPIN-OFFS.    The   Acquired   Companies   have   not
distributed  the  stock  of any  corporation  in a  transaction  satisfying  the
requirements  of Section 355 of the Code since  December 31, 2004, and the stock
of the Acquired  Companies has not been distributed in a transaction  satisfying

                  (m)      INVERSION   TRANSACTIONS.   None   of  the   Acquired
Companies is an expatriated  entity (as defined in Section  7874(a)(2)(A) of the

7874(a)(2)(B) of the Code).

                  (n)      INVESTMENTS IN UNITED STATES PROPERTY.  Except as set
forth  in  Section  3.6(n)  of the  Disclosure  Schedule,  none of the  Acquired

                  (a)      Each Acquired  Company has good and marketable  title
to all of the material assets (tangible or intangible)  purported to be owned by
such Acquired Company,  free and clear of all Security Interests.  Each Acquired
Company owns or leases all  tangible  assets  sufficient  for the conduct of its
business as presently conducted. Such tangible assets, taken as a whole, are all
of the tangible assets necessary for the conduct of the business of the Acquired
Companies as presently conducted, have been maintained in accordance with normal
industry practice,  are in functional operating condition and repair (subject to
normal  wear and tear) and are  suitable  for the  purposes  for which  they are

                  (b)      Section 3.7(b) of the Disclosure  Schedule sets forth
a list of all equipment,  motor vehicles and assets  (including IT Assets) which
have a book value as reflected on the Most Recent  Balance Sheet of over $10,000
and which are leased by the Company.  Each item of equipment,  motor vehicle and
other  asset that any  Acquired  Company has  possession  of pursuant to a lease
agreement or other  contractual  arrangement is in such condition  that, if such
item of  equipment,  motor vehicle or other asset were returned to its lessor or
owner on the Closing Date in accordance  with the applicable  lease or contract,

condition of such item of equipment, motor vehicle or other asset.

                  (a)      such  Lease is in full  force  and  effect,  and such
Lease affords the applicable  Acquired Company a valid leasehold interest to the
real property that is the subject of the Lease;

                  (b)      the  transactions  contemplated  by this Agreement do
not require  the consent of any other party to such Lease,  will not result in a
breach of or constitute  (with or without due notice or lapse of time or both) a
default under such Lease, and will not otherwise cause such Lease to cease to be

the terms thereof as in effect immediately prior to the Closing;

                  (c)      no  Acquired  Company  has  collaterally  assigned or
granted any Security Interest in such Lease; and

                  (d)      no  Acquired  Company  nor, to the  knowledge  of the
Company  or the  Selling  Securityholders,  any  other  party,  is in  breach or
violation of, or default under,  any such Lease,  and no event has occurred,  is
pending (including the transactions contemplated hereby) or, to the knowledge of
the Company or the Selling  Securityholders,  is  threatened,  which,  after the
giving  of  notice,  with  lapse  of  time,  or  otherwise,   would  permit  the
termination,  modification  or  acceleration  of rent  under such Lease or would
constitute a material breach or default by the applicable  Acquired  Company or,
to the knowledge of the Company or the Selling Securityholders,  any other party
under such Lease.

         3.10     INTELLECTUAL PROPERTY.

                  (a)      Section 3.10(a) of the Disclosure Schedule contains a

Companies,  together with the rights granted to the Acquired  Companies pursuant
to the agreements listed in Section 3.10(f) of the Disclosure Schedule and under
any  "shrink-wrap" or "click-wrap"  license  agreements,  are sufficient for the
continued   conduct  of  the  business  of  the  Acquired   Companies  in  every
jurisdiction where it is conducted after the Closing in the same

                                       16


manner as such  business  was  conducted  prior to the  Closing in all  material
respects,  and neither the execution of this Agreement nor the  consummation  of
any transaction  contemplated hereby will materially adversely affect any of the
rights of the  Acquired  Companies  with  respect  to the  Company  Intellectual
Property or third-party Intellectual Property licensed to the Acquired Companies
pursuant to the above-referenced  agreements. Each of the Acquired Companies has
taken all  necessary  or  desirable  action to maintain and protect each item of
Company  Intellectual  Property  that it owns  or uses in its  business  and has

Intellectual  Property or to maintain its effectiveness have been filed with the
relevant patent, copyright,  trademark or other authorities in the United States
or foreign  jurisdictions,  as the case may be, so that no item  required  to be
listed in Section 3.10(a) of the Disclosure Schedule has lapsed, expired or been
abandoned or canceled other than in the Ordinary Course of Business.

                  (b)      There exist no actions, charges, complaints,  claims,
demands or proceedings asserted by the Company,  the Selling  Securityholders or
any other Acquired  Company  alleging that any Person is or has interfered with,
infringed upon,  misappropriated,  violated or otherwise come into conflict with
any Company Intellectual  Property or IT Asset of any Acquired Company,  and, to
the knowledge of the Company or the Selling  Securityholders,  there is no basis
for any such action, charge, complaint, claim, demand or proceeding.

                  (c)      No  Acquired  Company  nor the  Company  Intellectual
Property has in the past or is now interfering with, infringing upon, violating,
constituting a  misappropriation  of, or otherwise coming into conflict with any

Company must license or refrain from using any  Intellectual  Property rights of
any third party).  Section 3.10(c) of the Disclosure Schedule lists each written
complaint,  claim or notice, or written threat thereof, received by any Acquired
Company alleging any such infringement, violation or misappropriation since July
29, 2004.  The Company has made  available to the Buyer a summary of all written
documentation in the Company's  possession  relating to claims or disputes known
to  the  Company  or  the  Selling   Securityholders   concerning   any  Company
Intellectual Property owned by any Acquired Company.

                  (d)      Section 3.10(d) of the Disclosure Schedule identifies
each  license  or other  agreement  currently  in effect  pursuant  to which any
Acquired  Company has licensed,  distributed or otherwise  granted any rights to
any third party with respect to, any Company Intellectual  Property. No Acquired
Company and, to the knowledge of the Company or the Selling Securityholders,  no
other  party to any such  license  or other  agreement  is in breach or  default
thereof  (including with respect to any exclusivity  provisions  thereof) and no
event has occurred that with or without notice or lapse of time would constitute
a  breach  or  default  thereof  (including  with  respect  to  any  exclusivity
provisions  thereof)  or  permit   termination,   modification  or  acceleration
thereunder, and all products sold pursuant to any such distribution,  license or
other  agreement to which any  Acquired  Company is a party are sold and used in
the territories where contractual rights are granted pursuant to such agreements
strictly in accordance  with the terms of such agreements and in accordance with
applicable Law.

                                       17


                  (e)      Section 3.10(e) of the Disclosure Schedule identifies

Acquired  Company  uses it,  if any  (excluding  non-customized,  off the  shelf
software  programs licensed by any Acquired Company pursuant to "SHRINK WRAP" or
"CLICK-THROUGH"  licenses).  No Acquired  Company  and, to the  knowledge of the
Company or the Selling  Securityholders,  no other party to any such  license or
other agreement is in breach or default  thereof  (including with respect to any
exclusivity  provisions  thereof) and no event has occurred that with or without
notice or lapse of time would constitute a breach or default thereof  (including
with  respect to any  exclusivity  provisions  thereof)  or permit  termination,
modification  or  acceleration  thereunder.  No  Acquired  Company  has made any
payments to any third Person in connection  with the procurement or grant to any
Acquired Company of any distribution rights.

                  (f)      Section 3.10(f) of the Disclosure Schedule identifies
each sponsoring,  research and development or other agreement entered into since
July 29, 2004  (whether  expired or currently  in effect)  pursuant to which any
Acquired  Company has  sponsored or otherwise  collaborated  in the research and
development of Intellectual  Property. No Acquired Company and, to the knowledge
of the  Company  or the  Selling  Securityholders,  no  other  party to any such
agreement  currently  in force is in breach or default  thereof and no event has
occurred that with or without notice or lapse of time would  constitute a breach
or  default  thereof  or  permit   termination,   modification  or  acceleration
thereunder.

                  (g)      The  Acquired  Companies  have  exercised a degree of
care that is consistent with the standards of the industry in which the Acquired
Companies  operate  (but in no event less than a  reasonable  degree of care) in
order to protect the  secrecy  and  maintain  the  confidentiality  of all trade
secrets of the Acquired Companies,  including the adoption of a policy requiring
that all employees and independent  contractors who are involved in the creation
of Intellectual  Property for the Acquired  Companies enter into  non-disclosure
and invention  assignment  agreements in the Acquired Companies' standard forms.
Each  such  employee  and  independent  contractor,  if any,  has  executed  and
delivered to the Company or another  Acquired  Company such an agreement and, to
the  knowledge  of the  Company  or the  Selling  Securityholders,  none of such
employees or independent  contractors,  if any, is in violation thereof.  To the
knowledge  of the Company or the Selling  Securityholders,  no trade  secret has
been  disclosed  or  authorized  to be  disclosed  to any third party other than
pursuant to a  non-disclosure  agreement that  adequately  protects the Acquired
Companies' proprietary interests in and to such trade secrets.

                  (h)      All right,  title, and interest in and to the Company

jointly with others,  and regardless of whether conceived on or off the premises
of an Acquired  Company or during business hours) is a work made for hire and is
owned by one of the  Acquired  Companies,  free and clear of any and all  liens,
licenses or other restrictions.

                  (i)      Section 3.10(i) of the Disclosure Schedule contains a
true,  accurate  and  complete  list of material IT Assets owned by, or used and
necessary  to conduct  the  business  of,  any  Acquired  Company  as  presently
conducted.

                  (c)      Except as set forth on Section 3.11 of the Disclosure

change in the business  relationship  with any Major Customer or Major Supplier,
and (ii) there has been no material dispute between any Acquired Company and any
Major Customer or Major Supplier.  No Acquired  Company has received any written
notice or, to the knowledge of the Company or the Selling  Securityholders,  any
oral notice,  that (x) any Major  Customer  intends to reduce its purchases from
any Acquired Company in any material respect or otherwise  intends to materially
adversely change its business relationship with any Acquired Company or (y) that
any Major  Supplier  intends  to  reduce  its sale of goods or  services  to any
Acquired  Company in any  material  respect or otherwise  intends to  materially
adversely change its business relationship with any Acquired Company.

                  (d)      The Company has made available to the Buyer a copy of
each written  agreement listed or required to be listed in Sections 3.10 or 3.11
of the Disclosure  Schedule (the "SCHEDULED  AGREEMENTS").  Neither any Acquired
Company nor, to the knowledge of the Company or the Selling Securityholders, any
other party,  is in material breach or default under,  any Scheduled  Agreement,
and no event has occurred,  is pending (including the transactions  contemplated
hereby) or, to the knowledge of the Company or the Selling  Securityholders,  is
threatened,  which  (with or without  due notice or lapse of time or both) would
constitute  a  material  breach or default by any  Acquired  Company  or, to the
knowledge of the Company or the Selling Securityholders, any other party under a
Scheduled Agreement.

         3.12     ACCOUNTS  RECEIVABLE.  All trade accounts receivable and other
receivables of any Acquired  Company  reflected on the Most Recent Balance Sheet
are valid  receivables and are not subject to material setoffs or counterclaims,
except as  reflected  in reserves on the Most Recent  Balance  Sheet.  All trade
accounts  receivable  and other  receivables  of any Acquired  Company that have
arisen since the Most Recent  Balance Sheet Date are valid  receivables  and are
not  subject  to  setoffs or  counterclaims,  are  current  and  collectible  in
accordance  with their  terms  within 90 days of Closing  (with  respect to U.S.
customers of any Acquired  Company) and within 180 days of Closing (with respect
to non-U.S.  customers of any Acquired Company),  in each case at their recorded

         3.14     INSURANCE.  Section 3.14 of the Disclosure Schedule lists each
insurance  policy  (including  medical  malpractice,   fire,  theft,   casualty,
comprehensive general liability,  workers' compensation,  business interruption,
environmental,  product liability and automobile insurance policies and bond and
surety  arrangements) to which any Acquired Company is a party, all of which are
in full force and effect.  There is no  material  claim  pending  under any such
policy as to which  coverage  has been  questioned,  denied or  disputed  by the
underwriter of such policy. All premiums due and payable under all such policies
have been paid or reflected in the  Financial  Statements  (unless such premiums
became due after the date of the Financial  Statements),  no Acquired Company is
liable for  retroactive  premiums,  and each  Acquired  Company is  otherwise in
compliance in all material respects with the terms of such policies. No Acquired
Company, nor to the knowledge of the Company or the Selling Securityholders, any
other  party to such  policy is in  material  breach or default and no event has
occurred that,  with the notice or the lapse of time,  would  constitute  such a
material breach or default, or permit termination, modification, or acceleration
under  the  policy  and,  to  the  knowledge  of  the  Company  or  the  Selling
Securityholders,  no party has repudiated  any provision of any such policy.  To
the  knowledge  of  the  Company  or the  Selling  Securityholders  there  is no
threatened termination of, or premium increase with respect to, any such policy.
Each such  policy  will  continue  to be in full  force and  effect  immediately
following  the  Closing  in  accordance  with the  terms  thereof  as in  effect
immediately prior to the Closing.

         3.15     LITIGATION. Section 3.15 of the Disclosure Schedule sets forth
all claims, suits, actions and proceedings pending by or before any Governmental
Entity or  arbitrator  to which any Acquired  Company is a party.  Except as set
forth in Section 3.15 of the Disclosure  Schedule,  there are no claims,  suits,
actions or proceedings  pending,  relating to, affecting or, to the knowledge of
the  Company or the Selling  Securityholders,  threatened  against any  Acquired
Company,  by or before any Governmental Entity or any arbitrator or by any third
party nor, to the  knowledge of the Company or the Selling  Securityholders,  is
there any reasonable basis therefor. There are no injunctions, judgments, orders
or decrees of any Governmental  Entity or arbitrator  outstanding,  relating to,
affecting  or, to the  knowledge of the Company or the Selling  Securityholders,
threatened against any Acquired Company.  Except as set forth in Section 3.15 of
the Disclosure  Schedule,  since July 29, 2004, there has been no investigation,
inquiry, review, notice of violation or complaint made, issued, filed or, to the
knowledge  of the  Company or the  Selling  Securityholders,  threatened,  by or
before any  Governmental  Entity or any  arbitrator  or by any third  party with
respect to or involving any Acquired Company.

         3.16     EMPLOYEES.

list of all current employees of the Acquired Companies whose annual base salary
exceeds  $25,000  per year,  along  with the  position  and the  annual  rate of
compensation  of each such  person.  No  Acquired  Company  employee at the Vice
President  level or higher  has  provided  notice of such  employee's  intent to
terminate  employment  with such  Acquired  Company and, to the knowledge of the
Company or the Selling  Securityholders,  no such  employee  presently  plans to
terminate employment with such Acquired Company.

                  (b)      No Acquired  Company is now or has been a party to or
bound by any  collective  bargaining or similar  agreement,  nor during the past
five years has any Acquired

                                       21


Company  experienced  any  strikes,   slowdowns,  work  stoppages,   grievances,
lockouts,  claims of  unfair  labor  practices  or other  collective  bargaining
disputes and, to the knowledge of the Company or the Selling Securityholders, no
such strikes, slowdowns, work stoppages,  grievances, lockouts, claims of unfair
labor practices or other collective  bargaining  disputes are threatened.  There
are no labor unions or other organizations,  either currently or within the past
five years,  representing,  purporting  to represent or, to the knowledge of the
Company or the Selling Securityholders, attempting to represent any employees of
any Acquired Company.

                  (c)      To the  knowledge  of  the  Company  or  the  Selling
Securityholders,  no Acquired  Company has violated any law, order,  judgment or
arbitration award of any court, arbitrator or government authority regarding the
terms and conditions of employment of employees, former employees or prospective
employees or other labor related matters,  including any laws, orders, judgments
or awards  relating  to wrongful  discharge,  discrimination,  personal  rights,
leaves of absence, wages, hours, collective bargaining,  fair labor standards or
occupational health and safety.

                  (d)      Each Acquired Company has properly  classified all of
its service  providers as either  employees  or  independent  contractors.  Each
Acquired Company has withheld and paid to the appropriate governmental authority
all amounts required to be withheld from  compensation paid to its employees and
is not liable for any arrears of Taxes,  penalties  or other sums for failure to
withhold and pay applicable Taxes. Each Acquired Company has paid in full to its
employees  or  adequately  accrued  for in  accordance  with GAAP or  applicable
foreign Laws,  all wages,  salaries,  commissions,  bonuses,  benefits and other
compensation due to or on behalf of such employees. There is no claim in dispute
against  any  Acquired  Company  with  respect to  payment  of wages,  salary or
overtime pay that has been asserted or is now pending or threatened with respect
to any current or former service providers of such Acquired Company.

                  (e)      In the  three  years  prior  to the date  hereof,  no
Acquired Company has effectuated (i) a "PLANT CLOSING" (as defined in the Worker
Adjustment  and  Retraining  Notification  Act (the "WARN  ACT") or any  similar

facilities  or operating  units within any site of employment or facility of any
Acquired  Company,  or (ii) a "MASS  LAYOFF" (as defined in the WARN Act, or any
similar  state,  local or  foreign  law)  affecting  any site of  employment  or
facility of any Acquired Company. No Acquired Company has material  Liabilities,
whether contingent or absolute,  relating to workers' compensation benefits that
are not fully insured against by a bona fide  third-party  insurance  carrier to
the extent  required by  applicable  Law.  With  respect to each state  workers'
compensation arrangement that is funded wholly or partially through an insurance
policy or public or private  fund,  all  premiums  required to have been paid to
date under such insurance policy or fund have been paid.

                  (f)      Section 3.16(f) of the Disclosure Schedule sets forth
any and all  indebtedness  in excess of  $10,000  owed by any  current or former
employee,  consultant  or  director  of any  Acquired  Company  to any  Acquired

including the U.S. Department of Labor, the IRS and the Pension Benefit Guaranty
Corporation,  within the three years preceding the date hereof and relating to a

with  applicable  Laws,  none of the  Acquired  Companies  has  made any plan or
commitment  to  create  any new or  additional  Company  Plan or to  modify  any
existing  Company  Plan  that  would  result  in  a  material  increase  in  the
compensation or benefits provided to any current or former employee,  consultant
or director  of any  Acquired  Company or the  spouses,  beneficiaries  or other
dependents thereof.

                  (b)      Each of the Acquired  Companies  has, in all material
respects,  (i)  timely  made  or,  to the  extent  not yet due,  accrued  on its
consolidated  financial statements,  all required  contributions  (including all
employer contributions and employee salary reduction contributions) thereto, and
(ii)  timely paid all  premiums  and  expenses to or in respect of such  Company
Plan. Each of the Acquired  Companies and each Company Plan are in compliance in

Except as set forth on Section  3.17(b) of the Disclosure  Schedule,  no Company
Plan or  related  trust  holds  assets  that  include  securities  issued by any
Acquired Company.

                  (c)      With respect to each Company Plan, (i) no breaches of
fiduciary  duty or  other  failures  to act or  comply  in  connection  with the
administration  or investment of the assets of a Company Plan in connection with
which any Acquired  Company or a fiduciary could reasonably be expected to incur
a  material  Liability  have  occurred;   and  (ii)  no  non-exempt   prohibited
transaction  within the meaning of Section  406 of ERISA or Section  4975 of the
Code that could  reasonably  be expected to result in material  Liability to any
Acquired  Company has  occurred;  and (iii) no lien has been  imposed  under the
Code, ERISA or any comparable foreign law.

                  (d)      There are no Legal Proceedings  (including any audits
or investigation  by the IRS, the U.S.  Department of Labor, the Pension Benefit
Guaranty  Corporation  or any  other  federal,  state  or  foreign  Governmental
Authority),  except claims for benefits  payable in the normal  operation of the
Company  Plans,  pending  or, to the  knowledge  of the  Company or the  Selling
Securityholders, threatened, against, by, on behalf of, relating to or involving
any Company Plan.

                                       23


                  (e)      Each  Company  Plan that is intended to be  qualified
under  Section  401(a) of the Code has  received a  favorable  determination  or
opinion  letter  from  the  IRS  on  which  each  Acquiring  Company  that  is a
participating  employer  in such  Company  Plan is  entitled  to rely and (i) no
prototype  plan  has been  modified  or  amended  such  that  the plan  would be
considered an individually  designed plan, (ii) no such determination or opinion
letter has been revoked and revocation has not been threatened, and (iii) no act
or omission has occurred that would  reasonably be expected to adversely  affect
the  qualification  of such Company Plan.  Each Company Plan that is intended to
qualify  under any law of any foreign  jurisdiction  has  received  any required
approval of a governmental  authority of a foreign  jurisdiction  which approval
has not been  revoked  and,  to the  knowledge  of the  Company  or the  Selling
Securityholders,  no event or circumstance exists that has adversely affected or
is likely to adversely affect such qualification or approval.

                  (f)      No Company  Plan is, and no Acquired  Company nor any
ERISA  Affiliate  maintains,  contributes to, or, in the six years preceding the
date of this  Agreement,  has  maintained or been  obligated to contribute to an
Employee  Benefit Plan subject to Section 412 of the Code,  Title IV of ERISA or
comparable   funding   obligations   imposed  under  the  laws  of  any  foreign
jurisdiction.

                  (g)      At no time in the six  years  preceding  the  date of
this Agreement has any Acquired Company or any ERISA Affiliate been obligated to
contribute  to any  "MULTIEMPLOYER  PLAN" (as defined in Section  4001(a)(3)  of
ERISA) or "MULTIPLE EMPLOYER PLAN" (as defined in Section 413(c) of the Code).

                  (h)      No Acquired Company has obligations under any Company
Plan or otherwise to provide benefits after termination of employment or service
to any current or former  employees,  consultants  or  directors of any Acquired
Company (or to any spouse,  dependent or beneficiary  of any of the  foregoing),
including obligations to provide health, accident,  disability or life insurance
coverage, but excluding continuation of health coverage required to be continued
under Section 4980B of the Code or other applicable law and insurance conversion
privileges  provided  under state law.  There has been no  communication  to any
current  or former  employee,  consultant  or  director  or any  retiree  of any
Acquired  Company,  or the spouses,  dependents or  beneficiaries  of any of the
foregoing,  that would  reasonably  be expected to promise or guarantee any such
health, accident, disability or life insurance coverage.

                  (i)      Neither the execution and delivery of this Agreement,
nor the consummation of the transactions contemplated hereby, either alone or in
combination  with another  event  (whether  contingent  or  otherwise)  will (i)
entitle any current or former  employee,  consultant or director of any Acquired
Company or any group of such employees,  consultants or directors to any payment
or benefit; (ii) increase the amount of compensation or benefits due to any such
employee,  consultant or director;  or (iii) accelerate the vesting,  funding or
time of payment of any compensation, equity award or other benefit.

                  (j)      Each  Company  Plan that is a  nonqualified  deferred
compensation   plan  subject  to  Code  Section  409A  has  been   operated  and

beginning January 1, 2005 through the date hereof.

                                       24


                  (k)      With   respect  to  each   Company   Plan   providing
compensation  or benefits to any  employee  or former  employee of any  Acquired
Company (or any dependent or  beneficiary  thereof) which is subject to the laws
of any jurisdiction outside of the United States (the "FOREIGN PLANS"): (i) such
Foreign Plan has been maintained in all material respects in accordance with all
applicable requirements and all applicable laws, (ii) if intended to qualify for
special  Tax  treatment,  such  Foreign  Plan  meets all  requirements  for such
treatment, (iii) if intended or required to be funded and/or book-reserved, such
Foreign Plan has been funded and/or book reserved,  as  appropriate,  based upon
reasonable  actuarial  assumptions,  and (iv) no  material  Liability  exists or
reasonably could be imposed upon the assets of any Acquired Company by reason of
such Foreign Plan.

                  (l)      Each  Acquired   Company  is  in  compliance  in  all
material  respects  with (i) the  requirements  of the  applicable  health  care
continuation and notice provisions of Section 4980B of the Code, as amended, and
the  regulations  (including  proposed  regulations)  thereunder and any similar
state  law,  and  (ii)  the  applicable  requirements  of the  Health  Insurance
Portability  and  Accountability  Act of 1996, as amended,  and the  regulations
(including the proposed regulations) thereunder.

                  (m)      Neither the execution and delivery of this Agreement,
nor the consummation of the transactions contemplated hereby, either alone or in
combination with another event (whether  contingent or otherwise) will result in
any "parachute  payment" under Code Section 280G (whether or not such payment is
considered to be reasonable compensation for services rendered).

Effect   that   causes  or   constitutes   a  breach  of  any  of  the   Selling

of  this  Agreement  that  would  cause  or  constitute  a  breach  of any  such
representation  or warranty had such  representation or warranty been made as of
the time of occurrence or discovery of such Effect.  During the same period, the

unlikely.  No disclosure by any Party pursuant to this Section 5.6(a),  however,
shall prevent or cure any misrepresentation or any breach of any representation,
warranty or covenant of the Company and the Selling Securityholders contained in
this Agreement or adversely  affect any of Buyer's rights or remedies under this
Agreement with respect thereto,  including,  without  limitation,  any rights to
indemnification pursuant to ARTICLE VII hereof; PROVIDED,  HOWEVER, that if such
disclosure is made by the Company and/or the Securityholders' Representatives by
a written supplement or amendment to the Disclosure  Schedule on or prior to the
second Business Day prior to the Closing Date,  referencing  this Section 5.6(a)
and the other relevant  Section(s) of this Agreement and the Disclosure Schedule
to which such  disclosure  relates,  and setting forth in reasonable  detail the
Effects that cause or constitute  such breaches or  misrepresentations,  and the
Buyer shall not have terminated this Agreement pursuant to Section 8.1(g) within
two Business Days after Buyer's  receipt of such  supplement or amendment to the
Disclosure Schedule, no Buyer

                                       34


Indemnified Party shall have any rights to  indemnification  pursuant to ARTICLE
VII in respect of such  specified  misrepresentations  or breaches  set forth in
such amendment or supplement to the Disclosure Schedule.

                  (b)      Between  the date of this  Agreement  and the Closing
Date,  the Buyer will  promptly (and in no event later than 24 hours) notify the
Company and the Securityholders'  Representatives in writing if it becomes aware
of any  Effect  that  causes  or  constitutes  a  breach  of any of the  Buyer's
representations  and  warranties  as of the  date  of this  Agreement,  or if it
becomes aware of any Effect after the date of this Agreement that would cause or
constitute   a  breach  of  any  such   representation   or  warranty  had  such
representation  or warranty  been made as of the time of occurrence or discovery
of such Effect. During the same period, the Buyer will promptly (and in no event
later than 24 hours) notify the Company and the Securityholders' Representatives
in writing if it becomes  aware of any breach of any covenant of the Buyer or of
any Effect  that may make the  satisfaction  of the  conditions  in Section  6.2
impossible  or unlikely.  No  disclosure  by the Buyer  pursuant to this Section
5.6(b),  however,  shall prevent or cure any  misrepresentation or any breach of
any  representation,  warranty  or  covenant  of the  Buyer  contained  in  this
Agreement  or  adversely  affect any of the Selling  Securityholders'  rights or
remedies  under  this  Agreement  with  respect  thereto,   including,   without
limitation,  any  rights to  indemnification  pursuant  to ARTICLE  VII  hereof;
PROVIDED,  HOWEVER,  that if such  disclosure  is made by the  Buyer by  written
notice to the Company and the  Securityholders'  Representatives  on or prior to
the second  Business  Day prior to the Closing  Date,  referencing  this Section
5.6(b)  and the  other  relevant  Section(s)  of this  Agreement  to which  such
disclosure  relates,  and setting  forth in  reasonable  detail the Effects that
cause or constitute such breaches or misrepresentations, and the Company and the
Selling Securityholders holding a majority of the outstanding Company Securities
shall not have terminated  this Agreement  pursuant to Section 8.1(h) within two
Business  Days  after  their  receipt  of  such  written   notice,   no  Selling
Securityholder shall have any rights to indemnification  pursuant to ARTICLE VII
in respect of such  specified  misrepresentations  or breaches set forth in such
written notice.

         5.7      DIRECTOR AND OFFICER INDEMNIFICATION.

                  (a)      Section  5.7 of the  Disclosure  Schedule  lists each
indemnification agreement or arrangement currently in place to which the Company
and one or more  current or former  officers  or  directors  of the Company is a
party.  From and after the Closing Date, the Buyer shall  indemnify,  defend and
hold  harmless,  to the fullest  extent  permitted  under  applicable  law,  the
individuals  who on or prior to the Closing  Date were  directors or officers of
any Acquired Company (collectively,  the "INDEMNITEES") with respect to all acts
or omissions by them in their  capacities as such or taken at the request of any
Acquired  Company at any time prior to the Closing  Date.  The Buyer agrees that
all  rights  of  the  Indemnitees  to   indemnification   and  exculpation  from
Liabilities  for acts or omissions  occurring at or prior to the Closing Date as
provided in the certificate of  incorporation or by-laws of any Acquired Company
as now in effect,  and any  indemnification  agreements or  arrangements  of any
Acquired Company shall survive the Closing Date and shall continue in full force
and effect in accordance with their terms. Such rights shall not be amended,  or
otherwise  modified in any manner that would adversely  affect the rights of the
Indemnitees, unless such modification is required by Law. In addition, the Buyer
shall pay any expenses of any Indemnitee  under this Section 5.7, as incurred to
the fullest extent permitted under applicable Law, PROVIDED, THAT, the person to
whom

                                       35


expenses  are advanced  provides an  undertaking  to repay such  advances to the
extent required by applicable Law.

                  (b)      For the six-year period commencing  immediately after
the Closing  Date,  the Buyer shall  maintain  in effect the  Company's  current
directors'  and  officers'   liability  insurance  covering  acts  or  omissions
occurring  prior to the  Closing  Date with  respect  to those  persons  who are
currently covered by the Company's  directors' and officers' liability insurance
policy on terms with respect to such  coverage  and amount no less  favorable to
the Company's  directors and officers  currently  covered by such insurance than
those of such policy in effect on the date hereof; PROVIDED, THAT, the Buyer may
substitute  therefor  policies  of a  reputable  insurance  company the terms of
which,  including  coverage and amount,  are no less favorable to such directors
and officers than the insurance  coverage  otherwise required under this Section
5.7(b).

                  (c)      The  provisions of this Section 5.7: (i) are intended
to be for the benefit of, and shall be enforceable by, each  Indemnitee,  his or
her heirs and his or her  representatives;  and (ii) are in addition to, and not
in substitution  for, any other rights to  indemnification  or contribution that
any such person may have by contract or otherwise.

                  (d)      The  obligations  of the Buyer under this Section 5.7
shall not be terminated or modified in such a manner as to adversely  affect any
Indemnitee to whom this Section 5.7 applies  without the consent of the affected
Indemnitee (it being expressly  agreed that the Indemnitees to whom this Section
5.7 applies shall be third-party beneficiaries of this Section 5.7).

                  (e)      Notwithstanding  anything  in this  Agreement  to the
contrary,  Buyer shall not be required to indemnify any  Indemnitee  pursuant to
this  Section  5.7,  and no  Selling  Securityholder  shall be  entitled  to any
indemnification  pursuant  to  this  Section  5.7 in his or her  capacity  as an
Indemnitee,  with respect to any matter for which a Buyer  Indemnified  Party is
entitled to indemnification pursuant to ARTICLE VII hereof.

         5.8      EMPLOYMENT MATTERS.

                  (a)      EMPLOYEE BENEFITS.  Prior to Closing, each individual
who is an  employee of any  Acquired  Company  immediately  prior to the Closing
shall be offered the  opportunity  to  continue as an employee of such  Acquired
Company immediately after the Closing (each, a "CONTINUING EMPLOYEE"). Effective
as of the  Closing  Date and until the first  anniversary  thereof,  subject  to
Section  5.8(b)  below,  the  Buyer  shall  cause  the  Company  (or  one of its
Affiliates after the Closing) to provide to each Continuing  Employee health and
welfare  benefits that are, in the  aggregate,  substantially  comparable to the
health and welfare benefits provided to such Continuing  Employee as of the date
of this Agreement. For the avoidance of doubt, for purposes of this Section 5.8,
"health and welfare" benefits shall not include any cash or equity compensation,
or any  vacation or other Paid Time Off  accrual.  For  purposes of  determining
eligibility to participate and vesting where length of service is relevant under
any  benefit  plan or  arrangement  in which  any  Continuing  Employee  becomes
eligible to participate,  Continuing  Employees shall receive service credit for
service with any Acquired  Company  prior to the Closing Date to the same extent
such service credit was granted under comparable Company

                                       36


Plans. Buyer shall, to the maximum extent permitted under any applicable benefit
plans  or  arrangements  in  which  Continuing   Employees  become  eligible  to
participate,   (i)  cause  to  be  waived  all  limitations  as  to  preexisting
conditions,  exclusions and waiting  periods with respect to  participation  and
coverage requirements  applicable to the Continuing Employees;  and (ii) provide
each Continuing Employee with credit for any co-payments and deductibles paid in
the plan  year  including  the date on which  the  Continuing  Employee  becomes
eligible to participate in the applicable plans or arrangements of the Buyer, in
satisfaction of any applicable deductible or out-of-pocket requirements.

                  (b)      NO   THIRD-PARTY   RIGHTS;   NO  RIGHT  TO  CONTINUED
EMPLOYMENT.  No  provision  of this  Section  5.8 shall  create any  third-party
beneficiary  or other  rights in any  Continuing  Employee  or  former  employee
(including  any  beneficiary  or dependent  thereof) in respect of (i) continued
employment (or resumed  employment)  with Buyer,  any Acquired Company or any of
their  Affiliates,  or (ii) any  benefits  that  may be  provided,  directly  or
indirectly, under any Company Plans or any similar plan or arrangement which may
be  established  or  maintained by Buyer,  any Acquired  Company or any of their
respective  Affiliates.  No provision of this Section 5.8 shall obligate  Buyer,
any Acquired Company or any of their Affiliates to adopt or maintain any benefit
plan at any time.

         5.9      TAX MATTERS.

                  (a)      TAX RETURNS FOR PRE-CLOSING TAX PERIODS.  The Company
shall  prepare  or cause to be  prepared  in a manner  consistent  with the past
practices of the Acquired  Companies and timely file or cause to be timely filed
all Tax Returns for the Acquired  Companies required to be filed by the Acquired
Companies prior to the Closing (after taking into account any extensions) (each,
a "PRE-CLOSING TAX RETURN").  All such Pre-Closing Tax Returns shall be complete
and accurate in all material respects. The Company shall pay or cause to be paid
on a timely basis all Taxes due and payable in respect of such  Pre-Closing  Tax
Returns that are so filed. Each of the Acquired Companies shall accrue a reserve
in its books and records and Most Recent Financial Statements in accordance with
past  practices  for  Taxes  payable  by such  Acquired  Company  for  which  no
Pre-Closing  Tax Return is due prior to the Closing.  The Buyer shall prepare or
cause to be  prepared  in a manner  consistent  with the past  practices  of the
Acquired  Companies  and timely file or cause to be timely filed all Tax Returns
for the Acquired Companies for all Pre-Closing Tax Periods (but not for Straddle
Periods or any portion  thereof which are dealt with in Section 5.9(b)) that are
not  required to be and have not been filed prior to the Closing  Date (each,  a
"POST-CLOSING  TAX  RETURN");  PROVIDED,  HOWEVER,  that  subject to the Dispute
Notice  process  set forth in  Section  5.9(i)  below,  the  Buyer  shall not be
required to take a position or other method of  reporting  in such  Post-Closing
Tax Return if the Arbiter makes a determination  that such position or method of
reporting is not reasonably  likely to be sustained upon audit.  The Buyer shall
provide to the Securityholders'  Representatives drafts of all such Post-Closing
Tax  Returns  for review and  comment at least 30 days prior to the due date for
the filing of each such Post-Closing Tax Return,  including extensions,  or such
shorter  period  as is  necessary  to  allow  for  the  timely  filing  of  such
Post-Closing  Tax  Return.  Not later than 15 days after the Buyer has  provided
such Post-Closing Tax Return, the Securityholders'  Representatives shall notify
the Buyer of the existence of any objection, specifying in reasonable detail the
nature and basis of such objection,  the  Securityholders'  Representatives  may
have to any item set forth on such draft  Post-Closing  Tax  Return (a  "DISPUTE
NOTICE"). The Buyer and the Securityholders'

                                       37


Representatives  agree to consult and resolve in good faith any such  objection.
If any such  dispute  has not been  resolved by the due date for filing any such
Post-Closing Tax Return, the Buyer shall file such Tax Return on its due date in
such manner as it deems  appropriate,  and the Parties  shall submit any dispute
relating  to such Tax  Return,  including  whether an amended  return  should be
filed,  to the Arbiter in accordance  with the  procedures  set forth in Section
5.9(i).  Within 15 days after the date on which  Taxes are paid with  respect to
any  Post-Closing  Tax  Return (or if a dispute  relating  to the amount of such
Taxes has been  submitted  to the  Arbiter,  within 15 days after the  Arbiter's
determination is rendered),  the Buyer and the Securityholders'  Representatives
shall execute and the Buyer shall deliver written notice  instructing the Escrow
Agent to  distribute  to the Buyer from the Escrow Cash the  amount,  if any, by
which such Taxes of the Acquired  Companies in respect of such  Post-Closing Tax
Return (or if a dispute  relating to the amount of such Taxes was  submitted  to
the  Arbiter,  the amount of Taxes  determined  by the Arbiter to be the correct
amount of Taxes  owed)  exceed the reserve for Tax  Liability  (rather  than any
reserve for deferred Taxes  established to reflect  timing  differences  between
book and Tax  income)  shown on the face of the balance  sheet in the  Company's
Most Recent  Financial  Statements as adjusted for operations  and  transactions
through the Closing  Date in  accordance  with past custom and  practice of such
Acquired Companies in filing their Tax Returns.

                  (b)      APPORTIONMENT  OF TAXES  FOR  STRADDLE  PERIODS.  All
Taxes with  respect to or of the  Acquired  Companies  that relate to a Straddle
Period shall be apportioned to the Pre-Closing Tax Period as follows: (i) in the
case of Taxes that are  either  (A) based  upon or related to income,  receipts,
capital  or net  worth,  or (B)  imposed  in  connection  with any sale or other
transfer or assignment of property  (real or personal,  tangible or  intangible)
(other than Taxes on conveyances pursuant to this Agreement that are governed by
Section 5.9(f)),  such Taxes  apportioned to the Pre-Closing Tax Period shall be
deemed equal to the amount which would be payable if the Tax year ended with the
Closing Date;  and (ii) in the case of Taxes  imposed on a periodic  basis other
than those  described  in clause (i),  including  property  Taxes and similar ad
valorem  obligations,  such Taxes shall be deemed to be the amount of such Taxes
for the entire Straddle  Period (or, in the case of such Taxes  determined on an
arrears basis, the amount of such Taxes for the immediately  preceding  period),
multiplied  by a fraction the  numerator of which is the number of calendar days
in the period  ending on the Closing  Date and the  denominator  of which is the
number of  calendar  days in the  entire  period.  All  transactions  not in the
Ordinary  Course of Business  occurring  on the  Closing  Date after the Closing
shall be apportioned to a Post-Closing Tax Period.

                  (c)      TAX RETURNS  FOR  STRADDLE  PERIODS.  The Buyer shall
prepare or cause to be prepared in a manner  consistent  with the past practices
of the  Acquired  Companies  and timely file or cause to be timely filed all Tax
Returns for the Acquired  Companies for all Straddle  Periods (each, a "STRADDLE
PERIOD TAX  RETURN");  PROVIDED,  HOWEVER,  that  subject to the Dispute  Notice
process  provided in Section  5.9(i)  below,  the Buyer shall not be required to
take a position or other method of reporting in such Straddle  Period Tax Return
if the Arbiter makes a  determination  that such position or method of reporting
is not reasonably likely to be sustained upon audit.  Buyer shall provide to the
Securityholders'  Representatives drafts of all such Straddle Period Tax Returns
for review and  comment at least 30 days prior to the due date for the filing of
each such  Straddle  Period Tax Return,  including  extensions,  or such shorter
period as is necessary to allow for the timely  filing of such  Straddle  Period
Tax Return. Not later than 15 days after Buyer has provided such Straddle Period
Tax Return, the Securityholders'

                                       38


Representatives  shall  provide  to Buyer  any  Dispute  Notice.  Buyer  and the
Securityholders'  Representatives agree to consult and resolve in good faith any
such  objection.  If any such dispute has not been  resolved by the due date for
filing any such Straddle Period Tax Return, the Buyer shall file such Tax Return
on its due date in such manner as it deems  appropriate,  and the Parties  shall
submit any dispute  relating to such Tax  Return,  including  whether an amended
return should be filed,  to the Arbiter in accordance  with the  procedures  set
forth in Section  5.9(i).  Within 15 days after the date on which Taxes are paid
with respect to any Straddle Period Tax Return (or if a dispute  relating to the
amount of such Taxes has been submitted to the Arbiter, within 15 days after the
Arbiter's  determination  is  rendered),  the  Buyer  and  the  Securityholders'
Representatives  shall  execute  and the  Buyer  shall  deliver  written  notice
instructing the Escrow Agent to distribute to the Buyer from the Escrow Cash the
amount,  if any,  by  which  such  Taxes  of the  Acquired  Companies  that  are
attributable  to the Straddle Period pursuant to Section 5.9(b) (or if a dispute
relating to the amount of such Taxes was submitted to the Arbiter, the amount of
Taxes  determined by the Arbiter to be the correct  amount of Taxes owed),  when
added  to  any  Taxes  of the  Acquired  Companies  payable  in  respect  of any
Post-Closing  Tax Return pursuant to Section 5.9(a),  exceed the reserve for Tax
Liability  (rather than any reserve for deferred  Taxes  established  to reflect
timing differences between book and Tax income) shown on the face of the balance
sheet  in the  Company's  Most  Recent  Financial  Statements  as  adjusted  for
operations  and  transactions  through the Closing Date in accordance  with past
custom and practice of such Acquired Companies in filing their Tax Returns.

                  (d)      COOPERATION  ON  TAX  MATTERS.  Buyer,  the  Acquired
Companies, the Securityholders'  Representatives and the Selling Securityholders
shall cooperate  fully, as and to the extent  reasonably  requested by the other
party, in connection  with the filing of Tax Returns  pursuant to this Agreement
and any Tax Proceeding.  Such cooperation  shall include the retention and (upon
the other party's  request) the provision of records and  information  which are
reasonably  relevant  to any such Tax  Proceeding,  the  provision  of powers of
attorney  and  making  employees  available  on a mutually  convenient  basis to
provide  additional   information  and  explanation  of  any  material  provided
hereunder. Buyer, the Acquired Companies, the Securityholders'  Representatives,
and the Selling  Securityholders' agree (i) to retain all books and records with
respect to Tax  matters  pertinent  to the  Acquired  Companies  relating to any
Taxable  period  beginning  before the Closing Date until the  expiration of the
statute of limitations (and, to the extent notified,  any extensions thereof) of
the  respective  Taxable  periods,  plus 60 days,  and to  abide  by all  record
retention agreements entered into with any Taxing authority,  (ii) to deliver or
make  available  to Buyer on the  Closing  Date,  copies  of all such  books and
records,  and  (iii) if the other  party so  requests  in  writing,  Buyer,  the
Acquired  Companies,  the  Securityholders'  Representatives,  and  the  Selling
Securityholders, as the case may be, shall, before destroying or discarding such
books and  records,  allow the other  party to take  possession  of them at such
other party's expense.  Buyer and the Securityholders'  Representatives  further
agree, upon request, to use their commercially reasonable best efforts to obtain
any  certificate  or other  document from any  Governmental  Entity or any other
Person as may be necessary to mitigate,  reduce or eliminate  any Tax that could
be imposed (including with respect to the transactions contemplated hereby).

                  (e)      CONTEST  PROVISIONS.  If,  subsequent to the Closing,
Buyer or any Acquired  Company  receives notice of a Tax Proceeding with respect
to  any  Tax  Return  for  a  Pre-Closing  Tax  Period  for  which  the  Selling
Securityholders are or may be required to indemnify the Buyer

                                       39


or any Acquired  Company  pursuant to this Agreement,  then within 20 days after
receipt of such notice,  the Buyer shall notify in writing the  Securityholders'
Representatives of such notice;  provided,  that the failure of the Buyer or any
Acquired  Company to so notify  the  Securityholders'  Representative  shall not
relieve the Selling Securityholders of any indemnification  obligation hereunder
except to the extent that the defense of such Tax  Proceeding  is  prejudiced by
the failure to give such notice. The Securityholders' Representatives shall have
the  right to  control  the  conduct  and  resolution  of such  Tax  Proceeding,
PROVIDED, HOWEVER, that if any of the issues raised in such Tax Proceeding could
have an impact on Taxes of any Acquired  Company for a Post-Closing  Tax Period,
then (i) the Buyer shall have the opportunity to control jointly the conduct and
resolution of only the portion of such Tax Proceeding which could have an impact
on Taxes of any  Acquired  Company in any  Post-Closing  Tax Period and (ii) the
Securityholders'  Representatives  shall not  enter  into any  settlement  of or
otherwise  compromise any such Tax Proceeding  without the prior written consent
of the Buyer; and PROVIDED, FURTHER, that if the Selling Securityholders are not
reasonably  expected to fully indemnify Buyer pursuant to this Agreement for any
losses   arising   from   such  Tax   Proceeding,   then  the   Securityholders'
Representatives  shall  afford  Buyer the  opportunity  to control  jointly  the
conduct  and  resolution  of  such  Tax  Proceeding.   If  the  Securityholders'
Representatives  shall have the right to control the conduct and  resolution  of
such  Tax  Proceeding  but  elect in  writing  not to do so  within  ten days of
receiving  notice of such Tax  Proceeding,  then  Buyer  shall have the right to
control the conduct and resolution of such Tax Proceeding, PROVIDED, THAT, Buyer
shall keep the Securityholders'  Representatives informed of all developments on
a timely basis and Buyer shall not resolve such Tax  Proceeding in a manner that
could  reasonably  be  expected  to have an adverse  impact on the  indemnifying
parties'    indemnification    obligations    under   this   Agreement   without
Securityholders'   Representatives   written   consent,   which   shall  not  be
unreasonably  withheld,  conditioned  or delayed.  Each party shall bear its own
costs for participating in such Tax Proceeding.

                  (f)      CERTAIN TAXES. All transfer, documentary, sales, use,
stamp,  registration and other  substantially  similar Taxes and fees (including
any penalties and interest)  incurred in connection  with this Agreement and the
purchase by the Buyer of the Company Securities (collectively, "TRANSFER TAXES")
shall be paid by the Buyer when due,  and the Buyer and Selling  Securityholders
shall  jointly  prepare  and timely  file all  necessary  Tax  Returns and other
documentation  with respect to all such Transfer Taxes. Any expenses incurred in
making such filings shall be paid by the Buyer.

                  (g)      POWERS OF  ATTORNEY  AND OTHER  TAX  AGREEMENTS.  All
powers of attorney,  Tax sharing agreements or similar arrangements with respect
to or involving any Acquired  Company  shall be terminated  prior to the Closing
Date and,  after the Closing  Date,  such  Acquired  Company  shall not be bound
thereby or have any Liability  thereunder  for amounts due in respect of periods
ending on or before the Closing Date.

                  (h)      TAXES INDEMNIFIED.  The Selling Securityholders shall
be  responsible  for,  and shall  (without  any right of  contribution  from any
Acquired Company or any right of indemnification  against any Acquired Company),
indemnify,  defend and hold harmless the Buyer  Indemnified  Parties (as defined
herein) from and against any and all Taxes imposed by any Governmental Entity on
the Acquired  Companies with respect to any Pre-Closing  Tax Period  (including,
without  limitation,  the Taxes  contemplated in Sections 5.9(a) and (b)) to the

                                       40


extent that such Taxes are in excess of the provision for Taxes in the Company's
Most Recent  Financial  Statement as adjusted for  operations  and  transactions
through the Closing  Date in  accordance  with past custom and  practice of such
Acquired  Companies in filing their Tax Returns.  The Buyer shall be responsible
for, and shall indemnify and hold harmless the Selling Securityholders from, all
Taxes imposed by any Governmental  Entity on the Acquired Companies with respect
to any Post-Closing Tax Period. Any claim for  indemnification  pursuant to this
Section  5.9(h) shall be governed by the  provisions  of ARTICLE VII;  PROVIDED,
HOWEVER,  that the procedures for dealing with claims from Governmental Entities
relating  to Taxes  shall be governed  by Section  5.9(a)  rather  than  Section
7.3(a).

                  (i)      TAX RETURN  DISPUTE  RESOLUTION.  If a dispute arises
under Sections 5.9(a) or 5.9(c)  relating to the filing of any Tax Returns,  the
Securityholders' Representatives and the Buyer shall promptly consult each other
in an effort to resolve such dispute.  If any such point of disagreement  cannot
be  resolved  within  15  days  of the  date  of  consultation,  all  points  of
disagreement    concerning    such   Tax   Returns   shall   be   submitted   to
PricewaterhouseCoopers   LLP,  or  other   nationally   recognized   independent
accounting firm selected by the Buyer and the  Securityholders'  Representatives
(the "ARBITER").  The Buyer and the Securityholders'  Representatives each agree
to execute,  if requested by the Arbiter,  a reasonable  engagement  letter. All
fees  and  expenses  of the  Arbiter  shall  be  borne  equally  by the  Selling
Securityholders,  in accordance  with their Pro Rata Share,  and the Buyer.  The
Arbiter  shall  act  as  an  arbitrator  to  determine,   based  solely  on  the
presentations by the Securityholders'  Representatives and the Buyer, and not by
independent  review,  only those  issues  remaining  in dispute.  The  Arbiter's
determination shall be made within 30 days of its engagement, shall be set forth
in a written statement delivered to the Securityholders' Representatives and the
Buyer and shall be final and binding on the parties hereto.

         5.10     FIRPTA. Prior to the Closing, (i) the Company shall deliver to
the Buyer and to the IRS  notices  that the  Common  Shares  are not "U.S.  real
property  interests" in accordance with Treasury  Regulations under Sections 897
and 1445 of the Code, or (ii) each of the Selling  Securityholders shall deliver
to the Buyer certifications that they are not foreign persons in accordance with
the  Treasury  Regulations  under  Section  1445 of the Code,  in  either  case,
together with  authorization for Buyer to deliver such notices or certifications
to the IRS upon the Closing.

         5.11     WITHHOLDING  FORMS.  At or prior to the Closing,  each Selling
Securityholder  shall  deliver  to the Buyer a properly  completed  IRS Form W-9
establishing an exemption from backup withholding.

         5.12     FINANCIAL  STATEMENTS.  The Company  and the  Securityholders'
Representatives  each  agree to  cooperate  with the  Buyer in good  faith  with
respect to any filings  required by the Buyer or any of its Affiliates  with the
U.S.  Securities  and  Exchange  Commission  ("SEC")  and revise or prepare  any
financial  statements,  including the Financial  Statements  and a balance sheet
dated as of the  Closing  Date,  required to be included in any such filing in a
form  appropriate  for such filing,  and use its  commercially  reasonable  best
efforts to obtain any  consents  of  independent  accounting  firms  required in
connection therewith, at the Buyer's sole expense.

                                       41

indirectly, print, publish, divulge or communicate to any Person or use for his,
her or its own account any trade or business secret,  process,  method or means,
or any other  Confidential  Information  concerning any Acquired  Company.  Such
Party further agrees and acknowledges that all of such Confidential Information,
in any form, and copies and extracts thereof,  are and shall remain the sole and
exclusive  property of the Acquired Companies and upon termination of his or her
employment  with any  Acquired  Company,  the  Buyer or any of their  respective
Affiliates,  such Party shall return to the Acquired Companies the originals and

process to disclose any of the Confidential

                                       43


Information,  such Party will provide the Acquired  Companies with prompt notice
so that the Acquired  Companies may seek a protective order or other appropriate
remedy and/or waive compliance with this Section 5.17(c). In the event that such
protective order or other remedy is not obtained or that the Acquired  Companies
waive compliance with the provisions of Section 5.17(c), such Party will furnish
only that portion of the Confidential Information which is legally required.

         (d)      GENERAL.  Each of Georges Chappuis,  Ph.D.,  Silvia Dettwiler,
Tamara Sales,  Brian Conkle and Jurg Tschopp,  and their respective  Affiliates,
further  acknowledge and agree that: (i) the covenants contained in this Section
5.17 are essential elements of this Agreement and that but for the agreements of
such Party to comply with such covenants,  the Buyer would not have entered into
this Agreement; (ii) the covenants contained in this Section 5.17 are reasonable
and necessary in terms of time, area and geographic scope, and line of business;
(iii) the covenants  contained in this Section 5.17 are reasonable and necessary
in terms of time, area and geographic scope, and line of business to protect the
Acquired Companies' legitimate business interests, which include their interests
in protecting the Acquired Companies' (A) valuable Confidential Information, (B)
substantial relationships with customers,  suppliers,  licensors,  licensees and
other Persons  having  business  dealings with the Acquired  Companies,  and (C)

Affiliates, expressly authorize the enforcement of the covenants provided for in
this Section 5.17 by (A) the Buyer, the Acquired  Companies and their respective
Affiliates,  (B) the Buyers' and the Acquired Companies'  permitted assigns, and
(C) any  successor to any business of any Acquired  Company.  To the extent that
the  covenants  provided for in this Section 5.17 may later be deemed by a court
of  competent  jurisdiction  to be overly  broad with respect to its duration or
with respect to any particular  activity or geographic  area such that it is not
enforceable, the court of competent jurisdiction making such determination shall
have the power to reduce the duration or scope of such provision,  and to add or
delete  specific  words or  phrases  to or from such  provision,  to the  extent
necessary to render such provision enforceable.  Such provision, as so modified,
shall then be enforced by the Parties hereto.

Securityholder  shall  (without  any  right of  contribution  from any  Acquired
Company or any right of indemnification  against any Acquired Company),  jointly
and  severally  (except as expressly set forth in  subparagraphs  (a) and (b) of
this  Section  7.1)  indemnify,  defend  and hold  harmless  the  Buyer  and its
Affiliates and each of their respective directors,  officers,  employees, agents
and  representatives  (collectively,  the "BUYER INDEMNIFIED  PARTIES") from and
against any and all Damages incurred or suffered by such Buyer Indemnified Party
resulting from or arising out of (directly or indirectly) or in connection with:

                  (a)      any breach of or any inaccuracy in any representation
or  warranty of the Company or the  Selling  Securityholders  contained  in this

         representation  or warranty of the Buyer  contained in this  Agreement,
         the  Buyer  Certificate  or any  other  certificate  or other  document
         delivered by the Buyer pursuant to this  Agreement,  or in any Schedule
         or Exhibit hereto or thereto;

                           (ii)     any  breach  or   failure  to  perform   any

Damages.

         7.3      INDEMNIFICATION CLAIMS.

                  (a)      All  claims  for  indemnification   made  under  this
Agreement  resulting  from,  related to or arising  out of a  third-party  claim
against an  Indemnified  Party  (other  than a claim for Taxes,  which  shall be
governed  by Section  5.9(e))  shall be made in  accordance  with the  following
procedures. An Indemnified Party shall promptly deliver an Expected Claim Notice
to the Indemnifying Party of the commencement of any action,  suit or proceeding
relating to a third-party claim for which  indemnification  may be sought or, if
earlier,  upon the  assertion  of any such  claim by a third  party,  and if the
Indemnified Party is a Buyer  Indemnified  Party, the Buyer shall deliver a copy
of the Expected  Claim Notice to the Escrow Agent.  No  reasonable  delay on the
part of the Indemnified Party in notifying any Indemnifying  Party shall relieve
the Indemnifying Party from any obligation  hereunder unless (and then solely to
the extent) the  Indemnifying  Party is thereby  prejudiced.  Within 20 calendar
days after  delivery of such  notification,  the  Indemnifying  Party may,  upon
written notice thereof to the Indemnified  Party,  assume control of the defense

full  responsibility  for the  matter,  (b) the  Indemnifying  Party  reasonably
demonstrates  it has the  financial  resources  necessary to defend  against the
matter and  fulfill its  indemnification  obligations  and (c) the  Indemnifying
Party conducts the defense with reasonable diligence.  If the Indemnifying Party
does not assume  control of such defense,  the  Indemnified  Party shall control
such defense.  The Party not controlling such defense may participate therein at
its own expense;  PROVIDED,  THAT, if the Indemnifying  Party assumes control of
such defense and the Indemnified  Party  reasonably  concludes,  based on advice
from  counsel,  that the  Indemnifying  Party  and the  Indemnified  Party  have
conflicting  interests with respect to such action,  suit,  proceeding or claim,
the reasonable fees and expenses of counsel to the  Indemnified  Party solely in
connection  therewith  shall  be  considered  "Damages"  for  purposes  of  this

responsible  for  the  fees  and  expenses  of more  than  one  counsel  for all
Indemnified  Parties.  The Party  controlling  such defense shall keep the other

defense thereof and shall consider  recommendations made by the other Party with
respect thereto. The Indemnified Party shall not agree to any settlement of such
action, suit,  proceeding or claim, or admit any Liability with respect thereto,
without the prior written consent of the Indemnifying Party, which consent shall
not be unreasonably  withheld,  conditioned or delayed.  The Indemnifying  Party
shall not agree to any settlement of such action, suit, proceeding or claim that
does not include a complete release of the Indemnified  Party from all Liability
with respect  thereto or that imposes any  Liability  on the  Indemnified  Party
without the prior written consent of the Indemnified  Party, which consent shall
not be unreasonably withheld, conditioned or delayed.

Response,  in which the  Indemnifying  Party  shall  either:  (i) agree that the
Indemnified  Party is entitled  to receive  all of the Claimed  Amount (in which
case the Response shall be accompanied by a payment by the Indemnifying Party to
the  Indemnified  Party of the Claimed  Amount,  by check or by wire transfer of

                                       49

depleted or  released  pursuant  to the terms of this  Agreement  and the Escrow
Agreement,  the Buyer shall deliver to the Escrow Agent,  within three  Business
Days following the delivery of the Response,  a written  notice  executed by the
Indemnifying  Party and the Buyer  instructing the Escrow Agent to distribute to
Buyer such amount of Escrow Cash as is equal to the Claimed Amount),  (ii) agree
that the  Indemnified  Party is entitled to receive the Agreed  Amount (in which
case the Response shall be accompanied by a payment by the Indemnifying Party to
the  Indemnified  Party of the Agreed  Amount,  by check or by wire  transfer of
immediately available funds; PROVIDED, THAT, if the Indemnified Party is a Buyer

Agreement,  the Buyer shall deliver to the Escrow Agent,  within three  Business
Days following the delivery of the Response,  a written  notice  executed by the

30-calendar day period referred to in Section 7.3(d) below to the books, records
and other  information  in the  possession or control of the  Indemnified  Party

contrary,  all  distributions  to the Buyer  out of the  Escrow  Cash  shall not
include any interest or income accrued or earned with respect to the Escrow Cash

delivery of a Response that reflects a Dispute,  the Indemnifying  Party and the
Indemnified Party shall use commercially  reasonable best efforts to resolve the
Dispute.  If the Dispute is not resolved within such 30-calendar day period, the

Notice that is the subject of a Dispute.

                  (e)      Notwithstanding  the other provisions of this Section
7.3,  if a third  party  asserts  (other  than by  means of a  lawsuit)  that an
Indemnified Party is liable to such third party for a monetary  obligation which
may  constitute  or result in Damages  for which such  Indemnified  Party may be
entitled to  indemnification  pursuant to this ARTICLE VII, and such Indemnified
Party

                                       50


reasonably  determines  that it has a valid  business  reason  to  fulfill  such
obligation  and that such  Indemnified  Party or such  third  party is likely to
suffer  irreparable harm if the Indemnified Party follows the procedures in this
Section 7.3, then (i) such  Indemnified  Party shall be entitled to satisfy such
obligation,  without prior consent from the Indemnifying Party (PROVIDED,  THAT,
such Indemnified Party shall provide such notice to the Indemnifying Party as is
possible under the circumstances),  (ii) such Indemnified Party may subsequently
make a claim for  indemnification  in  accordance  with the  provisions  of this
ARTICLE VII, and (iii) such Indemnified Party shall be reimbursed, in accordance
with the  provisions  of this  ARTICLE VII, for any such Damages for which it is
entitled to  indemnification  pursuant to this ARTICLE VII (subject to the right
of the  Indemnifying  Party to dispute the  Indemnified  Party's  entitlement to
indemnification,  or the amount  for which it is  entitled  to  indemnification,
under the terms of this ARTICLE VII,  including the  application of Sections 7.4
or 7.5).

                  (f)      If a  Buyer  Indemnified  Party  makes  a  claim  for
indemnification  based on an alleged breach of any covenant in Section 5.17, the
Buyer  shall  promptly  notify  the  affected  Selling  Securityholder  and  the
Securityholders'   Representatives   of  such  claim,  and  the  Buyer  and  the
Securityholders'  Representatives  shall permit the affected  individual Selling
Securityholder to take over any defense and/or  settlement of such claim,  which
will be at the affected  Selling  Securityholder's  sole  expense.  Each Selling
Securityholder  agrees that the Securityholders'  Representatives  shall have no
obligation to defend any such claims and will not use any of the  Representative
Escrow Amount with respect to such claims.

                  (g)      For  purposes of this Section 7.3, (i) if the Selling
Securityholders   comprise  the  Indemnifying   Party,  any  references  to  the
Indemnifying  Party  (except  provisions  relating to an  obligation to make any
payments) shall be deemed to refer to the Securityholders' Representatives,  and
(ii)  if  the  Selling  Securityholders  comprise  the  Indemnified  Party,  any
references to the Indemnified Party (except provisions relating to an obligation
to make or a right to  receive  any  payments)  shall be  deemed to refer to the
Securityholders'  Representatives.  The Securityholders'  Representatives  shall
have full power and  authority on behalf of each of the Selling  Securityholders
to take any and all  actions on behalf of,  execute any and all  instruments  on
behalf  of,  and   execute  or  waive  any  and  all  rights  of,  the   Selling
Securityholders under this ARTICLE VII and the Escrow Agreement.

         7.4      SURVIVAL.

                  (a)      The  representations  and  warranties  set  forth  in
Sections  2.1(a),  2.1(b),  2.1(c)  and  2.1(e)  of  this  Agreement,   and  the
indemnification   obligations  relating  thereto,   shall  survive  the  Closing
indefinitely.  The  representations  and  warranties set forth in Section 3.6 of
this Agreement,  and the  indemnification  obligations  relating thereto,  shall
survive  the  Closing  through  the  expiration  of the  applicable  statute  of
limitations period. All other  representations and warranties of the Parties set
forth in this Agreement,  and the indemnification  obligations relating thereto,
shall  survive the Closing  and expire one year after the  Closing  Date.  If an
Indemnified  Party delivers to an  Indemnifying  Party,  before  expiration of a
representation  or  warranty,  either a Claim Notice based upon a breach of such
representation  or warranty,  or an Expected Claim Notice based upon a breach of
such representation or warranty, then the applicable  representation or warranty
shall  survive  until,  but only for purposes of, the  resolution  of the matter
covered by such notice. If the legal proceeding or written claim with respect to

                                       51


which an  Expected  Claim  Notice has been given is  definitively  withdrawn  or
resolved in favor of the Indemnified Party, the Indemnified Party shall promptly
so notify the Indemnifying  Party; and if the Indemnified  Party has delivered a
copy of the  Expected  Claim Notice to the Escrow Agent and Escrow Cash has been
retained in escrow after the termination  date set forth in the Escrow Agreement
with respect to such  Expected  Claim  Notice,  the  Indemnifying  Party and the
Indemnified  Party shall  promptly  deliver to the Escrow Agent a written notice
executed  by both  Parties  instructing  the  Escrow  Agent to  distribute  such
retained Escrow Cash to the Selling Securityholders in accordance with the terms
of the Escrow Agreement.

                  (b)      The covenants  contained in this  Agreement  which by
their terms apply or are to be  performed in whole or in part after the Closing,
and  the   indemnification   obligations   relating   thereto   (including   the
indemnification  obligations  of the  Parties  relating  to Taxes  contained  in
Section 5.9),  shall survive the Closing for the relevant statute of limitations
period, unless a different period is expressly contemplated herein.

         7.5      INDEMNIFICATION LIMITATIONS.

                  (a)      Notwithstanding  anything to the  contrary  contained
herein:

                           (i)      no  individual  claim (or  series of related

         inaccuracy in any  representation  or warranty set forth in Section 3.6
         or under Sections  7.1(d)  (regardless of whether or not the underlying
         liability is disclosed on Section  3.6(a) of the  Disclosure  Schedule)

         any  representation  or warranty set forth in Section 3.6), (b), (c) or
         (e) or  7.2(a)  shall be  assertable  unless it is (or they are) for an
         amount in excess of $100,000,  in the aggregate (the "GENERAL THRESHOLD
         AMOUNT" and,  together with the Tax Threshold  Amount,  the  "THRESHOLD
         AMOUNTS"); PROVIDED, HOWEVER, that once the applicable Threshold Amount
         is exceeded with respect to the relevant class of claims (i.e. $200,000
         for the Tax  Threshold  Amount and $100,000  for the General  Threshold
         Amount),  each claim of such class (or series of related  claims) shall
         be assertable for all such amounts (including the applicable  Threshold
         Amount), and the Parties shall be liable with respect to claims of such
         class  for  all  of  the  aggregate  Damages  related  to  such  claims
         (including the applicable Threshold  Amount)(subject to the limitations
         contained  in  subsections  (ii) and (iii) of this  Section  7.5(a) and
         Section 7.5(b) below);  PROVIDED,  FURTHER that any claim  described in
         clause (i)(x) above shall be applied  solely  towards the Tax Threshold
         Amount and not the General  Threshold Amount and any claim described in
         clause  (i)(y)  above  shall be  applied  solely  towards  the  General
         Threshold  Amount  and not  the Tax  Threshold  Amount;  and  PROVIDED,
         FURTHER  that the  limitations  in this  clause (i) do not apply to any
         claim relating to any breach of or any inaccuracy in any representation
         or warranty set forth in Sections 2.1(a),  2.1(b),  2.1(c) or 2.1(e) or
         any breach of any covenant or agreement set forth in Section 5.17,  and
         do not apply to any claim relating to Section 7.2(b);

                           (ii)     the  aggregate   Liability  of  the  Selling
         Securityholders  under this  ARTICLE  VII,  shall not exceed the Escrow
         Cash;  PROVIDED,  HOWEVER,  the limitation in this

                                       52


         clause  (ii) does not apply to any claim  relating  to any breach of or
         any inaccuracy in any  representation or warranty set forth in Sections
         2.1(a),  2.1(b),  2.1(c)  or 2.1(e) or any  breach of any  covenant  or
         agreement set forth in Section 5.17; and

                           (iii)    the  aggregate  Liability of the Buyer under
         this ARTICLE VII,  shall not exceed  $1,280,000;  PROVIDED,  THAT,  the
         limitation in this clause (iii) does not apply to any claim relating to
         Section 7.2(b).

                  (b)      Except  for any  breach of or any  inaccuracy  in any
representation  or  warranty  set forth in ARTICLE II or  Section  3.6,  for any
breach of any covenant or agreement  set forth in Section 5.17, or for any Taxes
for which the Buyer is  entitled to receive  payment  from the Escrow Cash or is
otherwise entitled to indemnification  pursuant to Section 5.9, any recovery for
indemnification  by any Buyer  Indemnified  Party  pursuant to this  ARTICLE VII
shall be made  solely  against  the Escrow  Cash  pursuant  to the terms of this
Agreement  and the  Escrow  Agreement.  With  respect  to any  breach  of or any
inaccuracy in any representation or warranty set forth in Section 3.6 or for any
Taxes for which the Buyer is entitled to receive payment from the Escrow Cash or
is otherwise entitled to  indemnification  pursuant to Section 5.9, any recovery
for  indemnification by any Buyer Indemnified Party pursuant to this ARTICLE VII
shall first be made  against the Escrow Cash and,  once the Escrow Cash has been
fully  released  under  the terms of the  Escrow  Agreement  at the  termination
thereof, the Buyer Indemnified Parties may recover for indemnification  pursuant
to this ARTICLE VII directly against the Selling Securityholders, subject to the
limitation set forth in subsection  (i) of Section  7.5(a);  PROVIDED,  HOWEVER,
that the aggregate Liability of the Selling  Securityholders  under this ARTICLE
VII with  respect  thereto from and after the date of such release of the Escrow
Cash shall not exceed the aggregate  amount of Escrow Cash (if any)  distributed
to the Selling Securityholders at the termination of the Escrow Agreement.  With
respect to any breach of or any inaccuracy in any  representation or warranty by
a Selling  Securityholder  set forth in Sections 2.1(d) or 2.1(f),  any recovery
for  indemnification by any Buyer Indemnified Party pursuant to this ARTICLE VII
shall first be made against such Selling  Securityholder's Pro Rata Share of the
Escrow Cash and, once such Selling Securityholder's Pro Rata Share of the Escrow
Cash has been fully  depleted,  the Buyer  Indemnified  Parties  may recover for
indemnification  pursuant to this  ARTICLE VII  directly  against  such  Selling
Securityholder, subject to the limitations set forth in subsections (i) and (ii)
of Section  7.5(a);  PROVIDED,  HOWEVER,  that the  aggregate  Liability of such
Selling  Securityholder  under this ARTICLE VII with respect  thereto  shall not
exceed the lesser of (i) his,  her or its Pro Rata Share of the  Purchase  Price
and (ii) the Escrow Cash. With respect to any breach of or any inaccuracy in any
representation  or  warranty by a Selling  Securityholder  set forth in Sections
2.1(a), 2.1(b), 2.1(c) or 2.1(e), or any breach of any covenant or agreement set
forth in Section 5.17 by a Selling  Securityholder  named in Section  5.17,  any
recovery for  indemnification  by any Buyer  Indemnified  Party pursuant to this
ARTICLE VII shall first be made against such Selling  Securityholder's  Pro Rata
Share of the Escrow Cash and, once such Selling  Securityholder's Pro Rata Share
of the Escrow Cash has been fully  depleted or has been released under the terms
of the  Escrow  Agreement  at the  termination  thereof,  the Buyer  Indemnified
Parties may recover for  indemnification  pursuant to this  ARTICLE VII directly
against such  Selling  Securityholder;  PROVIDED,  HOWEVER,  that the  aggregate
Liability  of such  Selling  Securityholder  under this ARTICLE VII with respect
thereto shall not exceed his, her or its Pro Rata Share of the Purchase Price.

                                       53


                  (c)      Except  with  respect  to  claims  based  on fraud or
willful breach or for injunctive relief or other equitable  remedies,  after the
Closing,  the rights of the Indemnified  Parties under this ARTICLE VII shall be
the sole and exclusive remedies of the Indemnified  Parties and their respective
Affiliates  with  respect to any and all claims  covered by this ARTICLE VII and
any and all claims otherwise  relating to the transactions  that are the subject
of this Agreement.

                  (d)      If the  Closing  occurs,  no  Selling  Securityholder
shall have any right of contribution against the Acquired Companies with respect
to any  breach  by the  Company  of  any  of  its  representations,  warranties,
covenants  or  agreements,  and  in  furtherance  of  the  foregoing,  upon  the
occurrence of the Closing, each Selling  Securityholder hereby fully and finally
releases  the Acquired  Companies  from any claim of any kind or nature for, and
waives  any and  all  rights  of  every  kind  or  character  with  respect  to,
indemnification  or contribution by the Acquired  Companies with respect to such
representations, warranties, covenants or agreements.

                  (e)      Notwithstanding anything to the contrary elsewhere in
this Agreement,  no Party shall, in any event, be liable to any other person for
any multiple, consequential,  incidental, indirect, special or punitive damages,
including loss of future revenue, income or profits, diminution of value or loss
of business  reputation or opportunity  relating to the breach or alleged breach
hereof.

                  (f)      Notwithstanding  any other  provision of this ARTICLE
VII,  the amount of  Damages  recoverable  by an  Indemnified  Party  under this
ARTICLE VII with respect to an indemnity claim shall be reduced by the amount of
(i) any payment  received by such Indemnified  Party (or an Affiliate  thereof),
with  respect to the  Damages to which such  indemnity  claim  relates,  from an
insurance  carrier  (including  with respect to insurance  against  professional
Liability) and (ii) the present value of any current or reasonably  expected Tax
deduction,  Tax  credit or other Tax  benefit  to such  Indemnified  Party  with
respect to the receipt of such  indemnity  payment or as a result of the Damages
(the "TAX  BENEFIT").  Damages  shall also  exclude any  Liability  based upon a
claim, assessment or deficiency for foreign,  federal, state and/or local income
or franchise  Taxes which arise from  adjustments  which have the effect only of
shifting income, credits and/or deductions from one fiscal period to another. An
Indemnified Party shall use commercially  reasonable best efforts to pursue, and
to cause its  Affiliates  to  pursue,  all  insurance  claims to which it may be
entitled  in  connection  with any  Damages it  incurs,  and the  Parties  shall
cooperate  with each other in  pursuing  insurance  claims  with  respect to any
Damages  or any  indemnification  obligations  with  respect to  Damages.  If an
Indemnified  Party (or an Affiliate)  receives any insurance payment or incurs a
Tax  Benefit in  connection  with any claim for Damages for which it has already
received an indemnification payment from the Indemnifying Party, it shall pay to
the Indemnifying  Party,  within 30 days of receiving such insurance  payment or
incurring  such Tax  Benefit,  an amount  equal to the  excess of (A) the amount
previously received by the Indemnified Party under this ARTICLE VII with respect
to such claim plus the amount of the  insurance  payments  received  and any Tax
Benefit  incurred,  over (B) the  amount of Damages  with  respect to such claim
which the  Indemnified  Party has become  entitled to receive under this ARTICLE
VII.

                  (g)      Notwithstanding  any other  provision of this ARTICLE
VII, the Parties agree that if the effect of any  misrepresentation or breach of
any  representation  and warranty or covenant  contained in this Agreement,  the
Company Certificate, the Disclosure Schedule or any

                                       54


other  certificate  or other document  delivered by any Acquired  Company or the
Securityholders'  Representatives  pursuant to this  Agreement,  or in any other
Schedule  or  Exhibit  hereto or  thereto,  is that (i) the  amount of the trade
accounts  receivable  and other  receivables  or the  inventory  (including  raw
materials, work in process and finished goods) of the Acquired Companies (net of
reserves,  including  excess  inventory and obsolete items reflected on the Most
Recent Balance  Sheet) have been  overstated (it being hereby agreed that if the
misrepresentation  or breach relates  specifically  to the period of time within
which any trade accounts  receivable or other  receivables are  collectible,  if
such trade  accounts  receivable or other  receivables  are in fact collected in
full by any Acquired Company  subsequent to such represented  period of time but
prior to April 30, 2008, such misrepresentation or breach shall not be deemed to
have overstated the trade accounts receivables or other receivables reflected on
the Most Recent Balance Sheet for purposes of this Section 7.5(g)),  or (ii) the
amount of the Liabilities of the Acquired Companies (or the reserves established
therefor)   have  been   understated,   the  Buyer's   Damages  caused  by  such
overstatement or understatement, as applicable, shall in no event exceed the net
amount by which such overstated trade accounts receivable and other receivables,
such overstated  inventory and/or such understated  Liabilities  reduces, in the
aggregate, the Consolidated Net Working Capital; PROVIDED, HOWEVER, that nothing
contained in this Section 7.5(g) shall be deemed to limit (A) the calculation of
the Buyer's  Damages with respect to any  misrepresentation  or breach of any of
the  representations  and  warranties  contained  in  Section  3.6 or any of the
covenants  contained in Section 5.9 of this Agreement or (B) the indemnification
obligations  of the Selling  Securityholders  relating to such  representations,
warranties  and  covenants  or with  respect to any Taxes for which the Buyer is
entitled to receive  payment  from the Escrow Cash or is  otherwise  entitled to
indemnification  pursuant to Section 5.9.  For purposes of this Section  7.5(g),
all calculations shall be made in accordance with GAAP.

         7.6      TREATMENT  OF  INDEMNITY  PAYMENTS.  Any  payments  made to an
Indemnified Party pursuant to this ARTICLE VII shall be treated as an adjustment
to the Purchase Price for Tax purposes.

         7.7      SUBROGATION  OF  RIGHTS.  In the event any  payment is made in
respect of Damages pursuant to this ARTICLE VII, the Indemnifying Party who made
such payment  shall be  subrogated  to the extent of such payment to any related
rights of recovery of the  Indemnified  Party receiving such payment against any
third party other than any Buyer Indemnified  Party, the Company or any of their
respective Affiliates.

                                  ARTICLE VIII.

                                   TERMINATION

         8.1      TERMINATION  OF  AGREEMENT.  The  Parties may  terminate  this
Agreement, prior to the Closing, as provided below:

                  (a)      the Parties may  terminate  this  Agreement by mutual
written consent signed by the Buyer, the Company and the Selling Securityholders
holding a majority of the outstanding Company Securities;

                                       55
