     being equal to the average of the closing  sales  prices of Buyer's  Common

     shall be distributed  among the  Shareholders  in accordance with a written
     notice  (the   "Distribution   Notice")  from  Seller   setting  forth  the
     apportionment of the Shares among the Shareholders; and

          (ii)  deliver to  Fulbright & Jaworski  L.L.P.,  as escrow  agent (the
     "Escrow Agent"),  Thirty Six Thousand Three Hundred Fifty Seven (36,357) of
     the Shares (the "Escrowed  Shares"),  to be held in escrow  pursuant to the
     terms of an Escrow Agreement ("Escrow Agreement") substantially in the form
     of  Exhibit  D  as  security  for  the  Seller   Parties'   indemnification
     obligations under this Agreement.

     (c) Registration of the Shares.


                                       4



          (i) Buyer shall:

               (A) as soon as practicable after the Closing, taking into account
          Buyer's  other  registration  undertakings,  prepare and file with the
          Securities  and  Exchange   Commission   (the  "SEC")  a  registration
          statement on Form S-3 (the "Registration  Statement")  relating to the
          resale of the Shares by the Shareholders;

               (B) use its reasonable  efforts,  subject to receipt of necessary
          information  from the  Shareholders,  to cause the SEC to declare  the
          Registration  Statement effective as promptly as practicable after the
          Registration Statement is filed by Buyer;

               (C) promptly prepare and file with the SEC (and provide notice to
          the  Shareholders  of any such filing) such amendments and supplements
          to the  Registration  Statement and the prospectus  used in connection
          therewith  as may be  necessary  to keep  the  Registration  Statement
          effective  until the earlier of (I) the date all of the Shares covered
          by the Registration  Statement have been sold by the Shareholders,  or
          (II) the date that is the second  anniversary of the effective date of
          the Registration Statement;

               (D)  furnish  to  each  Shareholder  such  number  of  copies  of
          prospectuses as such  Shareholder  may reasonably  request in order to
          facilitate the public sale or other  disposition  by such  Shareholder
          pursuant  to the  Registration  Statement  of all or any of the Shares
          owned by such Shareholder;

               (E) notify  each  holder of Shares  covered by such  Registration
          Statement at any time when a prospectus  relating  thereto is required
          to be  delivered  under the  Securities  Act of 1933,  as amended (the
          "Securities  Act"), of the happening of any event as a result of which
          the prospectus  included in such  Registration  Statement,  as then in
          effect,  includes an untrue  statement of a material  fact or omits to
          state a material  fact  required to be stated  therein or necessary to
          make  the  statements  therein  not  misleading  in the  light  of the
          circumstances then existing. Buyer will use reasonable best efforts to
          amend or supplement  such prospectus in order to cause such prospectus
          not to include  any  untrue  statement  of a material  fact or omit to
          state a material  fact  required to be stated  therein or necessary to
          make  the  statements  therein  not  misleading  in the  light  of the
          circumstances then existing;  provided,  however,  that Buyer, in good
          faith,  may delay the filing of any such amendment or supplement for a
          reasonable  period  of time in order to  permit  Buyer  (A) to  effect
          disclosure or disposition or consummation of any transaction requiring
          confidential  treatment  which is being actively  pursued at such time
          and which would require  disclosure in the  Registration  Statement or
          (B) to  negotiate,  effect or  complete  any  transaction  which Buyer
          reasonably believes might be jeopardized,  delayed or made more costly
          to Buyer by disclosure in the Registration Statement; and

               (F) bear all  expenses  in  connection  with  the  procedures  in
          paragraphs  (A)  through  (E)  of  this  Section   1.5(c)(i)  and  the
          registration  of the Shares  pursuant to the  Registration  Statement,
          other than fees and expenses, if any, of counsel


                                       5



          and other  advisers to the  Shareholders  or  underwriting  discounts,
          brokerage fees and commissions incurred by the Shareholders, if any.

          (ii) (A) Notwithstanding the generality of the foregoing clauses, each
     Shareholder  agrees that upon notice from Buyer at any time or from time to
     time during the time the  prospectus  relating to the Shares covered by the
     Registration  Statement  and  proposed  to be sold by such  Shareholder  is
     required to be delivered  under the  Securities Act of the happening of any
     event as a result of which, in Buyer's opinion,  the prospectus included in
     the Registration Statement, as then in effect, includes an untrue statement
     of a material  fact or omits to state a material fact required to be stated
     therein or necessary to make the statements therein not misleading in light
     of  the  circumstances  then  existing,  such  Shareholder  will  forthwith
     discontinue such  Shareholder's  disposition of such Shares pursuant to the
     Registration  Statement until the time of such  Shareholder's  receipt of a
     supplement  to or an  amendment of such  prospectus  as may be necessary so
     that,  as  thereafter  delivered  to the  purchaser  of such  Shares,  such
     prospectus shall not include,  in Buyer's opinion, an untrue statement of a
     material  fact or omit to  state a  material  fact  required  to be  stated
     therein or necessary to make the statements therein not misleading in light
     of the circumstances then existing.

               (B)  Each  Shareholder   shall  furnish  Buyer  such  information
          regarding such  Shareholder and the distribution of the Shares covered
          by  the  Registration  Statement  as  Buyer  may  from  time  to  time
          reasonably request in writing.

               (C) Each  Shareholder  agrees to give at least  two (2)  Business
          Days' prior written notice to Buyer of any proposed sale of the Shares
          covered by the  Registration  Statement  pursuant to the  Registration
          Statement  and not to make such sale (I) unless such two (2)  Business
          Days elapse  without  response from Buyer,  or (II) in the event Buyer
          sends such Shareholder written notice stating that an amendment to the
          Registration  Statement or supplement to the prospectus  must be filed
          in accordance with the second sentence of Section 1.5(c)(i)(E),  until
          Buyer notifies the Shareholders  that the  Registration  Statement has
          been amended or the  prospectus  supplemented  as required;  provided,
          however,  that  Buyer  agrees to file  such  amendment  or  supplement
          promptly upon the  resolution of the  disclosure  issue  necessitating
          such delay,  or, in any event,  not more than 30 days after receipt of
          Buyer's written notice.

          (iii) Buyer will use its commercially  reasonable efforts to cause the
     Shares covered by and to be sold pursuant to the Registration  Statement to
     be listed on any securities  exchanges or markets on which shares of Common
     Stock are then listed.

          (iv) (A) In the event of a registration of any of the Shares under the
     Securities Act pursuant to this Section  1.5(c),  Buyer will, to the extent
     permitted by applicable law,  indemnify and hold harmless each  Shareholder
     against all losses,  claims,  damages or liabilities,  joint or several, to
     which such  Shareholder  may become subject under the  Securities  Act, the
     Securities  Exchange Act of 1934,  as amended (the  "Exchange  Act") or any
     other  federal or state  statutory law or  regulation,  or at common law or
     otherwise (including in settlement of any litigation, if such settlement is
     effected  with the  written  consent  of Buyer),  insofar  as such  losses,
     claims, damages or liabilities


                                       6



     (or actions in respect  thereof)  arise out of or are based upon any untrue
     statement or alleged untrue statement of any material fact contained in the
     Registration Statement, including the prospectus,  financial statements and
     schedules,  and all other documents filed as a part thereof,  as amended at
     the time of  effectiveness  of the  Registration  Statement,  including any
     information  deemed to be a part  thereof  as of the time of  effectiveness
     pursuant to paragraph (b) of SEC Rule 430A, or pursuant to SEC Rule 434, or
     the  prospectus,  in the form first filed with the SEC pursuant to SEC Rule
     424(b),  or  filed  as part of the  Registration  Statement  at the time of
     effectiveness  if no Rule 424(b)  filing is required,  or any  amendment or
     supplement  thereto,  or arise out of or are  based  upon the  omission  or
     alleged  omission to state  therein a material  fact  required to be stated
     therein or necessary to make the  statements  therein not  misleading,  and
     will  reimburse  each  such  Shareholder  for any  legal or other  expenses
     reasonably  incurred by such Shareholder in connection with  investigating,
     defending,  settling,  compromising or paying any such loss, claim, damage,
     liability or action;  provided,  however,  that Buyer will not be liable in
     any such case if and to the  extent  that any such loss,  claim,  damage or
     liability  arises  out of or is based upon an untrue  statement  or alleged
     untrue statement or omission or alleged omission so made in conformity with
     information  furnished in writing by such Shareholder  specifically for use
     in such Registration  Statement.  For purposes of this Section  1.5(c)(iv),
     the term  "Registration  Statement"  shall  include  any final  prospectus,
     exhibit,  supplement  or  amendment  included  in or  relating  to, and any
     document incorporated by reference in, the Registration  Statement referred
     to in Section 1.5(c)(i).

          (B) Each Shareholder,  severally and not jointly,  will, to the extent
     permitted by  applicable  law,  indemnify  and hold  harmless  Buyer,  each
     person,  if any,  who controls  Buyer within the meaning of the  Securities
     Act,  each officer of Buyer who signs the  Registration  Statement and each
     director  of Buyer,  against all losses,  claims,  damages or  liabilities,
     joint or  several,  to which Buyer or such  officer or director  may become
     subject under the Securities  Act, the Exchange Act or any other federal or
     state statutory law or regulation, or at common law or otherwise (including
     in settlement of any  litigation,  if such  settlement is effected with the
     written  consent  of the  Shareholders),  insofar as such  losses,  claims,
     damages or liabilities (or actions in respect  thereof) arise out of or are
     based upon any untrue statement or alleged untrue statement of any material
     fact contained in the Registration Statement or any amendment or supplement
     thereof, or arise out of or are based upon the omission or alleged omission
     to state therein a material fact required to be stated therein or necessary
     to make the statements therein not misleading, and will reimburse Buyer and
     each such officer,  director,  underwriter and  controlling  person for any
     legal or other  expenses  reasonably  incurred by them in  connection  with
     investigating  or  defending  any such loss,  claim,  damage,  liability or
     action;  provided,  however, that such Shareholder will be liable hereunder
     in any such  case if and only to the  extent  that  any such  loss,  claim,
     damage or liability  arises out of or is based upon an untrue  statement or
     alleged untrue statement of a material fact or omission or alleged omission
     of a material fact made in reliance upon and in conformity with information
     pertaining  to such  Shareholder  furnished  in  writing  to  Buyer by such
     Shareholder  specifically  for  use  in  the  Registration  Statement;  and
     provided further, however, that the liability of each Shareholder hereunder
     shall not in


                                       7



     any event exceed the proceeds  received from the sale of his Shares covered
     by such Registration Statement.

          (C) Promptly after receipt by an indemnified  party under this Section
     1.5(c)(iv)  of notice of the threat or  commencement  of any  action,  such
     indemnified party will, if a claim in respect thereof is to be made against
     an indemnifying  party under this Section  1.5(c)(iv),  promptly notify the
     indemnifying  party in writing  thereof;  but the omission to so notify the
     indemnifying party will not relieve it from any liability which it may have
     to any  indemnified  party for  contribution  or  otherwise  than under the
     indemnity  agreement  contained in this Section 1.5(c)(iv) to the extent it
     is not  prejudiced as a result of such failure.  In case any such action is
     brought against any indemnified  party and such indemnified  party seeks or
     intends to seek  indemnity from an  indemnifying  party,  the  indemnifying
     party will be  entitled to  participate  in, and, to the extent that it may
     wish, jointly with all other indemnifying  parties similarly  notified,  to
     assume the defense  thereof with counsel  reasonably  satisfactory  to such
     indemnified party; provided,  however, if the defendants in any such action
     include  both the  indemnified  party  and the  indemnifying  party and the
     indemnified  party  shall  have  reasonably  concluded  that there may be a
     conflict  between  the  positions  of  the   indemnifying   party  and  the
     indemnified  party in  conducting  the  defense of any such  action or that
     there  may be legal  defenses  available  to it  and/or  other  indemnified
     parties  which are different  from or additional to those  available to the
     indemnifying  party, the indemnified  party or parties shall have the right
     to select  separate  counsel to assume such legal defenses and to otherwise
     participate  in the  defense of such  action on behalf of such  indemnified
     party or parties.  Upon  receipt of notice from the  indemnifying  party to
     such  indemnified  party of its  election  so to assume the defense of such
     action and approval by the indemnified  party of counsel,  the indemnifying
     party  will not be liable to such  indemnified  party  under  this  Section
     1.5(c)(iv)  for any legal or other expenses  subsequently  incurred by such
     indemnified  party in connection  with the defense  thereof  unless (1) the
     indemnified  party shall have employed such counsel in connection  with the
     assumption  of  legal  defenses  in  accordance  with  the  proviso  to the
     preceding  sentence (it being  understood,  however,  that the indemnifying
     party  shall  not be liable  for the  expenses  of more  than one  separate
     counsel,  approved by such indemnifying party in the case of paragraph (A),
     representing all of the indemnified parties who are parties to such action)
     or (2) the  indemnified  party shall not have employed  counsel  reasonably
     satisfactory to the indemnifying  party to represent the indemnified  party
     within a reasonable time after notice of commencement of action, in each of
     which cases the  reasonable  fees and  expenses of counsel  shall be at the
     expense of the indemnifying party.

          (D) In order to provide for just and equitable  contribution  to joint
     liability  under the  Securities  Act in any case in which  either  (1) any
     indemnified  party exercising rights under this Agreement makes a claim for
     indemnification  pursuant to this Section  1.5(c)(iv)  but it is judicially
     determined  (by the  entry  of a final  judgment  or  decree  by a court of
     competent  jurisdiction  and the expiration of time to appeal or the denial
     of the last right of appeal) that such  indemnification may not be enforced
     in such case notwithstanding the fact that this Section 1.5(c) provides for
     indemnification in such case, (2) contribution under the Securities Act may
     be required on the part of any such


                                       8



     indemnified  party in circumstances for which  indemnification  is provided
     under this Section 1.5(c), or (3) the indemnification  provided for by this
     Section 1.5(c) is insufficient to hold harmless an indemnified party, other
     than by reason of the exceptions  provided therein,  then, and in each such
     case, Buyer and the Shareholders  will contribute to the aggregate  losses,
     claims,  damages  or  liabilities  to  which  they  may be  subject  (after
     contribution  from  others) (x) in such  proportion  as is  appropriate  to
     reflect the relative  fault of the  indemnifying  party on the one hand and
     the  indemnified  party on the other or (y) if the  allocation  provided by
     clause (x) above is not permitted by  applicable  law, or provides a lesser
     sum to the indemnified  party than the amount  hereinafter  calculated,  in
     such  proportion as is  appropriate  to reflect not only the relative fault
     referred to in clause (x) above but also the relative  benefits received by
     the indemnifying  party and the indemnified  party from the registration of
     the  securities as well as the  statements or omissions  which  resulted in
     such  losses,  claims,  damages  or  liabilities  and  any  other  relevant
     equitable considerations. No Shareholder will be required to contribute any
     amount in  excess  of the  proceeds  received  from the sale of its  Shares
     covered by such  Registration  Statement  and no person or entity guilty of
     fraudulent  misrepresentation  (within the meaning of Section  11(f) of the
     Securities Act) will be entitled to contribution  from any person or entity
     who was not guilty of such fraudulent misrepresentation.

          (v) The  obligations  of the Buyer  and the  Shareholders  under  this
     Section  1.5(c)(iv)  shall  survive  completion  of any  offering of Shares
     pursuant  to a  Registration  Statement  and  the  termination  of  Buyer's
     obligations under Section 1.5(c)(i).  No indemnifying party, in the defense
     of any such claim or  litigation,  shall,  except  with the consent of each
     indemnified  party,  consent  to entry of any  judgment  or enter  into any
     settlement  which does not  include as an  unconditional  term  thereof the
     giving by the claimant or plaintiff to such indemnified  party of a release
     from all liability in respect to such claim or litigation.

     (d) Allocation.  Within 30 days following the Closing Date, Buyer,  subject
to the approval of Seller,  shall prepare and finalize a schedule  setting forth
an allocation of the consideration  described in Section 1.5(a) among the Assets
(the  "Allocation  Schedule").  Each  party  agrees to report  the  transactions
contemplated   hereby  for  federal  income  tax  and  all  other  tax  purposes
(including,  without limitation,  for purposes of Section 1060 of the Code) in a
manner  consistent  with the  Allocation  Schedule,  and in accordance  with all
applicable rules and regulations,  and to take no position inconsistent with the
allocation set forth therein in any  administrative  or judicial  examination or
other  proceeding.  Each of Buyer and Seller shall  timely file the  appropriate
forms in accordance  with the  requirements of Section 1060 of the Code and this
Section.

     1.6 Excluded Assets. Anything to the contrary  notwithstanding,  the Assets
shall not  include  any of the  following  rights,  properties  or  assets  (the
"Excluded Assets"):

     (a) This  Agreement,  and any of the  other  documents  to be  executed  in
connection herewith (collectively,  the "Other Transaction  Documents"),  or any
right,  title or  interest  of Seller or any of the  Shareholders  hereunder  or
thereunder;

     (b) The Shares;


                                       9



     (c) Any rights of Seller or any of the  Shareholders  to tax refunds or any
accrued prepaid taxes;

     (d) Any and all rights of Seller with respect to the account receivable, in
the amount of $53,893, from Lawrence F. Miller;

     (e) Any and all  rights of Seller  with  respect to any  claims,  causes of
action,  choses in action,  rights of recovery and rights of set-off of any kind
with respect to SourceOne Financial LLC;

     (f) Any records relating to the internal governance of Seller; or

     (g) Any  insurance  policies  of Seller or any right,  title or interest of
Seller or any of the Shareholders  thereunder,  including any prepaid  insurance
premiums to the extent allocable to periods following the Closing Date.

     2. Representations and Warranties of Seller and the Shareholders

     Seller and the Shareholders  hereby,  jointly and severally,  represent and
warrant to Buyer as follows:

     2.1   Organization   and  Standing.   Seller  (a)  is  a  corporation  duly
incorporated,  validly existing and in good standing under the laws of the State
of Washington, (b) has full right, power and authority to enter into and perform
and do all things  contemplated  under this Agreement and the Other  Transaction
Documents to which it is a party  necessary to give effect to the  provisions of
this Agreement and such Other Transaction Documents, to own and lease the Assets
and to carry on and operate the Business as now being  conducted and proposed to
be conducted by it under existing agreements,  (c) is duly qualified or licensed
to do  business  and is in good  standing  as a  foreign  corporation  in  every
jurisdiction  in which the  character  of the  Assets or nature of the  Business
requires such  qualification,  and (d) does not own any of the Assets,  and does
not  conduct  any  of the  Business,  through  any  other  corporation,  limited
liability company, partnership or other entity.

     2.2  Authorization  and Binding  Obligations.  The execution,  delivery and
performance by Seller of this Agreement and the Other  Transaction  Documents to
which Seller is a party have been duly and validly  authorized  by all necessary
corporate action,  including approval of the entire transaction by the requisite
vote  of  Seller's  shareholders.  This  Agreement  and  the  Other  Transaction
Documents  to which Seller is a party have been duly  executed and  delivered by
Seller and  constitute  valid and binding  agreements of Seller,  enforceable in
accordance with their respective terms,  except as their  enforceability  may be
limited by  bankruptcy,  insolvency,  moratorium  or other laws  relating  to or
affecting creditors' rights generally and the exercise of judicial discretion in
accordance with general  equitable  principles.  The  Shareholders  are the sole
owners of the issued and outstanding capital stock of Seller.

     2.3 No  Contravention.  The  execution,  delivery and  performance  of this
Agreement and the Other  Transaction  Documents to which Seller is a party,  the
consummation  of the  transactions  contemplated  hereby  and  thereby  and  the
compliance with the provisions


                                       10



hereof and thereof by Seller do not (a) violate any provision of the certificate
of  incorporation or bylaws of Seller,  (b) conflict with,  result in the breach
of, or  constitute a default  under,  or result in the creation of any Lien upon
any of the Assets, or require any authorization, consent, approval, exemption or
other action by or notice to any third  party,  court or other  governmental  or
administrative  body,  under the provisions of any agreement or other instrument
to which  Seller is a party or by which any of the Assets are bound or  affected
or (c) violate any laws, regulations, orders or judgments applicable to Seller.

     2.4  Compliance  with  Laws.  Seller  has  complied  with,  and  is  now in
compliance with, all laws, rules, regulations,  orders, judgments and decrees of
any governmental, regulatory or administrative body, agency or authority, or any
court or judicial  authority (each, an "Authority")  applicable to the Business.
Seller possesses each franchise, license, permit, authorization,  certification,
consent, variance,  permission,  order or approval of or from any Authority, and
has  filed  all  filings,   notices  or  recordings   with  any  such  Authority
(collectively,  "Licenses")  material to, or  necessary  for the conduct of, the
Business and is now and, has at all times in the past,  been in compliance  with
each of such  Licenses.  Each such  License is  identified  on Schedule  2.4. No
proceeding  or other  action is pending or, to the best  knowledge of Seller and
the Shareholders threatened,  to revoke, amend, or limit any License, and Seller
and the Shareholders have no basis to believe that any such proceeding or action
would result from the  consummation  of the  transactions  contemplated  by this
Agreement or by the Other Transaction Documents,  or that any such License would
not be renewed in the ordinary course.

     2.5  Environmental  and  Safety  Laws.  Seller is not in  violation  of any
applicable law relating to the  environment or  occupational  health and safety,
and, to the knowledge of Seller and the Shareholders,  no material  expenditures
are or will be required by Seller in order to comply with any such existing law.

     2.6 Tax Matters.  Seller has, within the times and in the manner prescribed
by law, filed all required tax returns, including sales and use tax returns, has
paid or provided  for all taxes,  including  sales and use taxes owed by Seller,
with respect to the  Business  (whether or not shown on any tax return to be due
and owing by it), has paid or provided for all deficiencies or other assessments
of taxes,  interest  or  penalties  owed by it,  and all such tax  returns  were
correct and complete in all material  respects when filed.  No taxing  Authority
has asserted,  or will successfully  assert, any claim for the assessment of any
additional  taxes of any nature with respect to any periods  covered by any such
tax returns, and all taxes or other charges required to be withheld or collected
by Seller with respect to the Business have been duly withheld or collected and,
to the  extent  required,  have  been paid to the  proper  taxing  Authority  or
properly segregated or deposited as required by law.

     2.7 Employee Benefit Plans; ERISA; Employees.

     (a) As used in this Agreement,  the term "ERISA Affiliate" means any person
or entity (whether or not  incorporated)  which,  by reason of its  relationship
with  Seller or a  subsidiary  is  required  to be  aggregated  with Seller or a
subsidiary  under  Sections  414(b),  414(c),  414(m) or 414(o) of the Code,  or
which,  together with Seller or a subsidiary  is a member of a controlled  group
within the meaning of Section 4001(a) of ERISA.


                                       11



     (b)  Schedule  2.7(b)  lists  each  "employee  benefit  plan" as defined in
Section  3(3) of  ERISA,  whether  or not  subject  to  ERISA,  and  each  other
employment, severance, consulting, confidentiality,  deferred, incentive, fringe
benefit,  change in control,  retention,  stock  option or other equity based or
other compensatory or benefit plan, policy, agreement or arrangement that (i) is
maintained,  administered,  contributed  to or required to be  contributed to by
Seller,  or its ERISA  Affiliates or to which Seller or any ERISA Affiliate is a
party,  and (ii) covers any current or former  employee  or other  personnel  of
Seller or any of its ERISA  Affiliates who provides or has provided  services to
or in connection with the Business (the "Business  Employees").  Each such plan,
policy,  agreement or arrangement is herein referred to as an "Employee  Benefit
Plan." Copies of the Employee Benefit Plans, including,  but not limited to, any
trust  instruments,  insurance  contracts and all  amendments  thereto have been
furnished to Buyer.  Neither  Seller nor any of its ERISA  Affiliates is or ever
was obligated to contribute to or a participating employer under a multiemployer
plan within the meaning of Section  3(37) of ERISA or an employee  pension  plan
covered by Title IV of ERISA, Section 302 of ERISA or Section 412 of the Code.

     (c) With respect to any funded employee  pension plan within the meaning of
Section 3(2) of ERISA,  there has been no accumulated  funding deficiency within
the meaning of Section  302(a)(2) of ERISA or Section 412 of the Code, which has
resulted or could result in the imposition of a Lien upon any of the Assets, and
no event has occurred and no circumstance exists under which Seller has incurred
or may incur, a liability  (directly or indirectly),  under Title IV of ERISA or
Section 4980B of the Code which could become a liability of Buyer or which could
result in the imposition of a Lien upon any of the Assets.

     (d) Schedule  2.7(d)  contains a true and complete  list of all  employees,
independent  contractors,  officers or  directors  of Seller who are employed or
performing  services  in the  Business  on the date  hereof  (collectively,  the
"Closing Date  Employees"),  the title and rate of  compensation of each Closing
Date  Employee,  and the amount of any accrued  bonuses,  vacation,  sick leave,
maternity  leave  and  other  leave  for such  personnel  as of the date of this
Agreement.  Except as set forth on Schedule 2.7(d), Seller has paid, on or prior
to the Closing Date,  or will pay,  promptly  following  the Closing  Date,  all
accrued  salary and  bonuses,  and  accrued  amounts for  vacation,  sick leave,
maternity leave and other leave due and payable on or prior to the Closing Date.
Seller has, on or prior to the Closing Date, notified each Closing Date Employee
that his or her  employment  by Seller  shall be  terminated  as of the Closing.
Except as set forth in Schedule 2.7(d), Seller is not in default with respect to
any  withholding or other  employment  taxes or payments with respect to accrued
vacation or severance  pay on behalf of any employee or  independent  contractor
for which it is obligated on the date  hereof,  and has made all such  necessary
payments  or  adjustments  arising  through  the  Closing  Date.  Seller has not
instituted   any  "freeze"  of,  or  delayed  or  deferred  the  grant  of,  any
cost-of-living  or  other  salary  adjustment  for any  Closing  Date  Employee.
Schedule 2.7(d) lists the name,  title and rate of compensation of each employee
of Seller whose  employment was  terminated  within 90 days prior to the date of
this  Agreement.  Seller  has  not  engaged  in any  unfair  labor  practice  or
discriminated on the basis of race, color, religion,  sex, national origin, age,
disability or handicap in its employment conditions or practices. No employee or
independent contractor has filed or, to the


                                       12



best knowledge of Seller and the Shareholders,  threatened any claims, and there
is no  reasonable  basis for a claim  against  Seller  relating to employment or
similar matters (including, without limitation,  compensation and benefits) with
Seller.  There are not in existence or, to the best  knowledge of Seller and the
Shareholders,  threatened any work stoppages respecting employees or independent
contractors of Seller or unfair labor practice complaints against Seller. Seller
is not a  party  to  any  collective  bargaining  agreement,  no  representation
question  exists  respecting  the  Closing  Date  Employees  and  no  collective
bargaining  agreement  is  currently  being  negotiated  by Seller  covering its
employees,  nor is any grievance  procedure or  arbitration  proceeding  pending
under  any  collective  bargaining  agreement  and no  claim  therefor  has been
asserted.  Seller has not received notice from any union or any employee setting
forth demands for representation,  elections or for present or future changes in
wages, terms of employment or working  conditions.  There have been no audits of
the equal employment opportunity practices of Seller, nor does any basis for any
such audit exist. Seller does not have any severance agreement, policy, practice
or other  arrangement  with respect to severance  with any Closing Date Employee
other than the Employee Benefit Plans.

     2.8 Litigation. Except for Kurt T. Johnson v. Advanced Acoustical Concepts,
Inc.,  et. al.,  Case No. 2001 CV 0833,  filed in the  Montgomery  County Common
Pleas  Court,  there is no pending or, to the best  knowledge  of Seller and the
Shareholders,  threatened,  adverse claim, dispute,  governmental investigation,
suit,  action,  arbitration,  legal,  administrative  or other proceeding of any
nature,  domestic or  foreign,  criminal  or civil,  at law or in equity,  by or
against or otherwise affecting the Business or the Assets.

     2.9 Agreements.

     (a) Schedule  2.9(a) sets forth a true and complete list of all  agreements
that  involve  payments  to or by Seller in  excess  of $5,000  individually  or
$15,000 in the aggregate,  including, without limitation, all sales orders taken
by Seller, commitments, including guarantees of any indebtedness, or instruments
binding  Seller as of the  Closing  Date with  respect  to the  Business  or the
Assets,  and all  powers  of  attorney.  True and  complete  copies of each such
agreement, commitment or instrument have been delivered to Buyer.

     (b) To the  best  knowledge  of  Seller  and the  Shareholders,  each  such
agreement is the valid and binding  obligation of the other  contracting  party,
enforceable  in all material  respects in accordance  with its terms against the
other  contracting  party,  except  as such  enforceability  may be  limited  by
applicable bankruptcy, insolvency,  reorganization,  arrangement,  moratorium or
other similar laws and by general  principles of equity,  has not been cancelled
in whole or in part and is in full force and effect.

     (c) Seller has  fulfilled  all material  obligations  required to have been
performed  by it prior to the date hereof with  respect to each such  agreement,
and neither Seller nor any  Shareholder has any reason to believe that the other
contracting party will not be able to fulfill all of its or his obligations when
due in respect thereof.

     (d) To the  best  knowledge  of  Seller  and  the  Shareholders,  no  other
contracting party to any such agreement is now in breach thereof,  and there are
not now,  nor have there been in the twelve (12) month  period prior to the date
hereof, any material disputes between Seller and any other contracting party.

     (e) Each such agreement shall be validly assigned to Buyer at Closing.


                                       13



     (f) Seller is not a party to, or bound by, any agreement or commitment that
restricts the conduct of the Business anywhere in the world.

     (g) Schedule  2.9(g) sets forth a true and complete  list of each  proposed
agreement,  commitment,   arrangement,  or  other  understanding  under  current
discussion between Seller and any third party that would, or reasonably could be
expected  to, be required to be  disclosed  pursuant  to any  provision  of this
Agreement,  if same had been executed  prior to and remained in effect as of the
date  hereof.  True and  complete  copies of the most recent  draft of each such
agreement  and  all  other  documents  evidencing  the  current  state  of  such
discussions have been delivered to Buyer.

     2.10 Suppliers and Customers.

     (a) Schedule  2.10(a) lists all of the  suppliers  and customers  with whom
Seller has done business  within six (6) months prior to the Closing  Date,  and
lists each  outstanding  purchase  order (or  correspondence  with  respect to a
proposed purchase order) by Seller with respect to the Business,  identifying in
each case the  vendor,  supplier,  contractor  or  inventor  and the items being
purchased and stating the quantity and price thereof.

     (b) Except for  delinquencies  in payment of the  suppliers  identified  on
Schedule  2.10(b),  the  relationships  of  Seller  with the  persons  listed in
Schedule 2.10(a) are good commercial working  relationships,  and no such person
has canceled or otherwise terminated,  or threatened to cancel or terminate, its
relationship with Seller, or decreased or limited  materially,  or threatened to
decrease or limit materially,  its business done with Seller, and neither Seller
nor any  Shareholder  has any reason to believe  that any such person  would not
continue  its  business   relationship  with  Buyer  following  the  Closing  on
substantially  the same terms as such person has  heretofore  done business with
Seller.

     2.11 Tangible  Property.  Except as set forth on Schedule 2.11,  Seller has
good and marketable title to each item of tangible  personal property that is an
Asset, free and clear of all liens and other encumbrances,  and, with immaterial
exceptions,  each such item of tangible  personal  property is in good operating
condition  and  repair,  ordinary  wear and tear  excepted,  and  useable in the
ordinary course of business. Schedule 2.11 contains a complete and accurate list
setting forth a description of each item of tangible  property that is an Asset,
and describes  the nature of Seller's  interest in any property  listed  thereon
that is not owned entirely by Seller free and clear of any Lien.

     2.12 Intellectual Property.

     (a) Seller owns, Buyer shall receive at Closing, and Seller's  intellectual
property  includes,  all assets described in Section 1.2(i) used in or necessary
for the  operation of the  Business.  Seller has no  registered  trademarks  and
service marks, reserved trade names,  registered copyrights,  issued patents, or
applications for any of the foregoing, used in or necessary for the operation of
the Business.

     (b) Schedule  2.12(b) sets forth the form and placement of the  proprietary
legends and  copyright  notices  displayed  in or on any of the  Assets,  or any
software programs


                                       14



included in the Assets.  In no instance  has the  eligibility  of such  software
programs for  protection  under  applicable  copyright law been forfeited to the
public domain.

     (c)  Seller has  promulgated  and used best  efforts  to protect  the trade
secrets of the Business.  There has been no material unauthorized  disclosure of
any trade  secrets of the Business by any person or entity.  The source code and
system  documentation  relating to any software  programs included in the Assets
have at all times been  maintained  in  confidence  and have been  disclosed  by
Seller only on a confidential basis and only to employees, consultants, vendors,
suppliers and customers having "a need to know" the contents thereof.

     (d)  All  personnel,   including  employees,   agents,   consultants,   and
contractors,  who have  contributed  to or  participated  in the  conception and
development of Seller's proprietary software programs,  technical documentation,
or  intellectual  property  with respect to the  Business,  either (i) have been
party to a  "work-for-hire"  arrangement or agreement with Seller, in accordance
with  applicable  federal  and state  law,  that by its terms  accords to Seller
ownership of all tangible and intangible  property thereby arising, or (ii) have
executed  appropriate  instruments  of assignment in favor of Seller as assignee
that by their terms convey to Seller  ownership  of all tangible and  intangible
property thereby arising.

     (e) No  intellectual  property  right or other claims have been asserted by
any  person or entity to the use of any Asset,  and Seller and the  Shareholders
are not aware of any valid basis for any such claim.  To the best  knowledge  of
Seller and the Shareholders, the use of any Asset by Seller does not infringe on
the intellectual property rights or other rights of any person or entity.

     (f) As of the Closing Date, all  intellectual  property  purchased by Buyer
pursuant  to this  Agreement  is and shall be useable in the same form as on the
Closing Date,  under the same  circumstances  as on the Closing Date, and in the
ordinary  course of the Business as such  business  actually  has been  operated
prior to the Closing Date.

     (g)  Seller (i) has good and  marketable  title to each  intangible  Asset,
including,  but not limited to, each item of  intellectual  property used in and
material to, or necessary for the operation of, the Business,  free and clear of
any  Lien,  and (ii) is the sole and  rightful  owner of all  right,  title  and
interest in and to each  intangible  Asset,  and has the  unrestricted  right to
market, license and otherwise exploit each intangible Asset.

     2.13 Third Party Components, Rights, etc.

     (a) Seller has validly and  effectively  obtained  the right and license to
use the  third-party  programs  included in the Assets and, with respect to such
third-party  programs,  such other rights and licenses as provided for under the
agreements relating thereto,  and Seller has the right to assign and transfer to
Buyer the foregoing rights and licenses.

     (b)  Except  as set  forth  on  Schedule  2.11,  Seller  has  not  granted,
transferred,  or assigned any right, title or interest in or to any Asset to any
person  or  entity.  There are no  contracts,  agreements,  licenses,  and other
commitments   and   arrangements  in  effect  with  respect  to  the  marketing,
distribution,  licensing,  or promotion of any material Asset by any independent
salesperson,   distributor,   sublicensor,   or   other   remarketer   or  sales
organization.


                                       15



     2.14 Insurance. Seller currently maintains the insurance policies set forth
on Schedule 2.14, which policies are in full force and effect and are sufficient
in amount (subject to reasonable  deductibles) to allow Seller to replace any of
its properties that might be damaged or destroyed.

     2.15 Seller's Financial Condition; Certain Transactions.

     (a) Except as set forth on Schedule 2.15(a), as of the date hereof,  Seller
has no direct or indirect indebtedness,  liabilities,  claims, losses,  damages,
deficiencies,  obligations  or  responsibilities,  liquidated  or  unliquidated,
accrued, absolute, contingent, or otherwise.

     (b) Since March 31, 2001 (the "Balance Sheet Date"), Seller has not:

     2.16  Seller  Financial  Statements.  Seller  has  delivered  to Buyer  (i)
Seller's  unaudited balance sheets as of December 31, 2000 and 1999, and related
statements of income,  cash flow and  shareholders'  equity for the fiscal years
then ended (the "Year-End Financials") and (ii) Seller's balance sheet as of the
Balance Sheet Date and as of July 15, 2001 (each, a "Balance Sheet") and related
unaudited  statements  of  income,  cash flow and  shareholders'  equity for the
periods ended on the respective dates of the Balance Sheets  (collectively,  the
"Interim  Financials").  The Year-End  Financials and the Interim Financials are
correct in all material  respects and have been prepared in material  compliance
with GAAP. The Year-End  Financials and Interim Financials present fairly in all
material respects the financial  condition,  operating results and cash flows of
Seller as of the dates and during the periods indicated therein, subject, in the
case of the Interim Financials,  to normal year-end adjustments,  which will not
be material in amount or  significance.  A true,  correct and  complete  copy of
Seller's balance sheet as of July 15, 2001 is attached hereto as Exhibit E.

     2.17 No  Undisclosed  Liabilities.  Except as set forth on the Schedules to
this  Agreement,  Seller has no liability,  indebtedness,  obligation,  expense,
claim,  deficiency,  guaranty  or  endorsement  of any  type,  whether  accrued,
absolute, contingent, matured, unmatured or other (whether or not required to be
reflected in financial statements in accordance with GAAP) (each a "Section 2.17
Liability")  that has neither (i) been  reflected in or reserved  against in the
Balance  Sheets,  nor (ii) arisen  since the  respective  dates of each  Balance
Sheet,  in the ordinary course of business  consistent  with Seller's  practices
prior to that date, in an amount that,  when  aggregated  with all other Section
2.17 Liabilities, exceeds Ten Thousand Dollars ($10,000).

     2.18 Loans,  Notes, Cash Accounts  Receivable and Accounts Payable.  Seller
has  provided  Buyer with an accurate and  complete  breakdown  and aging of all
accounts receivable,  notes receivable and other receivables of Seller as of the
Balance Sheet Date and as of July 15, 2001. All receivables (a) have arisen only
from bona fide  transactions in the ordinary course of business  consistent with
past  practice,  (b) represent  valid  obligations,  and (c) are current and are
expected to be  collectible in the aggregate  face amounts  thereof  without any
counterclaim or set-off when due,  except to the extent of the normal  allowance
for doubtful accounts with respect to accounts receivable that are computed in a
manner consistent with


                                       17



GAAP and as  reflected  in such  balance  sheet or with  respect to  receivables
arising  subsequent  to the Balance  Sheet Date,  as  reflected in the books and
records of Seller, and (d) are owned by Seller free of all Liens. No discount or
allowance from any account  receivable of Seller as of the Closing Date has been
made or agreed to (other than customary payment discounts in the ordinary course
of business  consistent  with past  practice),  and no such  account  receivable
represents  billings prior to actual shipment of goods or provision of services.
Accounts  payable  of  Seller  reflected  on the  Balance  Sheets  arose and all
accounts  payable of Seller  arising after the dates  thereof have arisen,  from
bona fide transactions. For the purposes of this Agreement, any person or entity
shall be deemed to own  subject  to a Lien any  property  or asset  which it has
acquired  or holds  subject  to the  interest  of a vendor or  lessor  under any
conditional  sale agreement,  capital lease or other title  retention  agreement
relating to such property or asset.

     2.19  Interested  Party  Transactions.  Neither  the  Shareholders  nor any
manager of Seller (nor, to the actual knowledge of Seller and the  Shareholders,
any  ancestor,  sibling,  descendant  or spouse of any of such  persons,  or any
trust, partnership or corporation in which any of such persons has or has had an
interest), has or has had, directly or indirectly, (i) an interest in any entity
that furnished or sold, or furnishes or sells, services,  products or technology
that Seller  furnishes  or sells,  or  proposes to furnish or sell,  or (ii) any
interest in any entity that purchases from or sells or furnishes to Seller,  any
goods or services,  or (iii) a beneficial  interest in any agreements of Seller;
provided,  however,  that  ownership  of no more  than one  percent  (1%) of the
outstanding voting stock of a publicly traded corporation shall not be deemed to
be an "interest in any entity" for purposes of this Section 2.19.

     2.20  Assets.  Except for the  Excluded  Assets,  the Assets are all of the
assets, properties,  goodwill, and rights of every nature, kind and description,
whether tangible or intangible,  real, personal or mixed, wherever located, used
in and material to, or necessary for the operation of, the Business.

     2.21  Brokers  or  Finders.  Seller has not  incurred,  and will not incur,
directly or indirectly,  any liability for brokerage or finders' fees or agents'
commissions or any similar charges in connection with this Agreement,  the Other
Transaction Documents or any transaction  contemplated hereby or thereby. Seller
and the  Shareholders,  jointly and  severally,  shall  indemnify and hold Buyer
harmless with respect to any claim by any broker,  agent,  or finder claiming to
have  acted on  behalf of Seller or the  Shareholders,  respecting  the  subject
matter hereof.

     2.22 No Misleading Statements.  No information furnished by or on behalf of
Seller to Buyer  contains any untrue  statement  of a material  fact or omits to
state a material  fact  necessary  to make such  statement,  in the light of the
circumstances under which it was made, not misleading.  All written information,
in whatever  form,  furnished  by Seller to Buyer was true and correct as of the
date so furnished and, except as the accuracy thereof is affected by the passage
of time,  remains  true and  correct  in all  material  respects  as of the date
hereof.

     6.3 Indemnification Procedure.

     (a) A party that may be entitled to indemnification pursuant to Section 6.1
or 6.2 (the  "Indemnitee")  shall  promptly  give  written  notice (a "Notice of
Claim")  to the party  liable for such  indemnification  (the  "Indemnitor").  A
Notice of Claim shall set forth (a) a description,  in reasonable detail, of the
facts and  circumstances  with  respect to the  subject  matter of such claim or
potential claim for indemnification, and (b) the anticipated total amount of the
indemnification claim (including any costs or expenses which have been or may be
reasonably incurred in connection therewith). Upon receipt of a Notice of Claim,
the  Indemnitor  may  elect  to  cure  the  circumstances  giving  rise  to  the
indemnification  claim (the "Event of Loss")  within  thirty (30) days after the
date of receipt of the Notice of Claim.  If such cure cannot be effected  within
such 30-day period,  payment of the amount of actual damage, loss, cost, expense
or liability (including  reasonable  attorneys' fees) (collectively,  "Damages")
due to the  Indemnitee  as set  forth in the  Notice  of Claim  shall be made by
Indemnitor no later than the  thirtieth  (30th) day after the date of the Notice
of Claim (or such later date as the Indemnitor  receives written notice that the
Indemnitee has suffered Damages). The Indemnitee's failure to give prompt notice
or to  provide  copies  of  documents  or to  furnish  relevant  data  shall not
constitute  a  defense  (in  whole or in part)  to any  claim by the  Indemnitee
against the Indemnitor for  indemnification,  except and only to the extent that
such failure shall have caused or increased such liability or adversely affected
the ability of the Indemnitor to defend against or reduce its liability.

     (b) If the  Indemnitor  shall  reject  any  Damages as to which a Notice of
Claim is sent by the  Indemnitee,  the  Indemnitor  shall give written notice of
such  rejection  to the  Indemnitee  within  thirty  (30) days after the date of
receipt of the Notice of Claim.

     (c) If any Notice of Claim  relates to any claim made against an Indemnitee
by a third person, the Notice of Claim shall state the nature,  basis and amount
of such claim. The Indemnitor shall have the right, at its election,  by written
notice to the  Indemnitee,  to assume the  defense of the claim as to which such
notice  has  been  given.  Except  as  provided  in the  next  sentence,  if the
Indemnitor so elects to assume such  defense,  it shall  diligently  and in good
faith defend such claim and shall keep the Indemnitee reasonably informed of the
status of such  defense,  and the  Indemnitee  shall  cooperate  fully  with the
Indemnitor  in the  defense  of such  claim,  provided  that in the  case of any
settlement  providing  for  remedies  other  than  monetary  damages  for  which
indemnification is provided,  the Indemnitee shall have the right to approve the
settlement, which approval shall not be unreasonably withheld or delayed. If the
Indemnitor  does not so elect to defend any claim as  aforesaid or shall fail to
defend any claim  diligently  and in good faith (after  having so elected),  the
Indemnitee may assume the defense of such claim and take such other action as it
may elect to defend or settle such claim as it may  determine in its  reasonable
discretion,  provided  that the  Indemnitor  shall have the right to approve any
settlement, which approval will not be unreasonably withheld or delayed.

     6.4 Limitations on Indemnification.


                                       26



     (a) Basket Amount.

          (i) The  indemnification  provided  for in Section 6.1 shall not apply
     until Buyer's claims for Damages exceed $25,000 in the aggregate, whereupon
     claim may be made for all amounts in excess of $25,000.

          (ii) The  indemnification  provided for in Section 6.2 shall not apply
     until Seller's and the Shareholders'  collective claims for indemnification
     exceed  $25,000  in the  aggregate,  whereupon  claim  may be made  for all
     amounts in excess of $25,000.

     (b) Indemnification Cap.  Notwithstanding  anything to the contrary in this
Agreement,  in no event shall the aggregate  amount of  collective  liability of
Seller and the  Shareholders  under  Section 6.1 or the liability of Buyer under
Section 6.2 (including all respective  costs,  expenses and attorneys' fees paid
or incurred by Seller, the Shareholders or Buyer in connection therewith) exceed
the Purchase Price.

     6.5  Payment of  Indemnification  Claims.  In the event that  Seller or the
Shareholders  are entitled to  indemnification  pursuant to Section  6.2,  Buyer
shall make  payment  of such  indemnification  claim in cash.  In the event that
Buyer is entitled to  indemnification  pursuant to Section  6.1,  the payment of
such  indemnification by Seller or the Shareholders shall be in cash;  provided,
however,  that  Buyer  may  elect to  satisfy  any  part of the  indemnification
obligation owed by any Shareholder  by, jointly with that  Shareholder,  causing
the  Escrow  Agent to return to Buyer an  integral  number  of  Escrowed  Shares
allocable  to such  Shareholder  Indemnitor  equal in value to the amount of the
indemnification obligation that Buyer has elected to satisfy in such manner. The
value of each such  Escrowed  Share shall be equal to the average of the closing
sale prices of the Common  Stock on the Nasdaq  National  Market  during the ten
(10)  trading  days  immediately  preceding  the date upon  which  Buyer and the
Indemnitor Shareholder request that the Escrow Agent return such Escrowed Shares
to Buyer.

reasonably necessary to effect, consummate, confirm or evidence the transactions
contemplated by this Agreement and the Other Transaction  Documents,  including,
without limitation (i) inventorying and listing of the Assets,  (ii) using their
best  efforts to obtain any third party  consents not obtained as of the Closing
Date, (iii) filing of tax returns, including,  without limitation, the filing of
sales and use tax  returns  and  notices  as any  party  hereto  may  reasonably
require,  (iv)  conducting,  at the expense of Buyer,  a financial  audit of the
Business in connection with the  integration of the financial  statements of the
Business into the financial  statements of the Buyer;  and (iv)  cooperating  to
facilitate the transition of Business customers and suppliers to Buyer.

     7.2  Delivery  of  Assets.  Seller  agrees  that it will  transfer  or make

accounting,  tax,  legal and other  records of the Business that shall come into
Buyer's  possession as a result of the  transactions  contemplated  hereby for a
period of not less than five (5) years from the Closing Date and give reasonable
access to Seller and the Shareholders, and Seller's officers, auditors, counsel,
and other  representatives for the purpose of preparing or defending tax returns
or for other reasonable business purposes.

shall,  upon the written request of Buyer,  immediately  destroy or erase all of
Seller's copies of computer software and Business records included in the Assets
and, upon Buyer's request,  promptly confirm  destruction of same by signing and
returning to Buyer an "affidavit of destruction"  acceptable to Buyer; provided,
however,  that  Seller  shall be  entitled  to  retain a copy of those  specific
records,  and only those specific records,  that contain information that (i) is
not related to the Business,  (ii) is neither  confidential  nor  privileged and
(iii) Seller has a reasonable need to retain.

     7.5 Non-Solicitation; Non-Competition.

     (a) For a period of two (2) years from the Closing Date,  Seller shall not,
without Buyer's prior written consent,  directly or indirectly,  (i) solicit the
employment of any officer,  senior manager or other key employee of Buyer or any
subsidiary  of Buyer or (ii)  hire any  officer,  senior  manager  or other  key
employee whose employment Buyer or any subsidiary of Buyer has terminated within
90 days of such  solicitation  or hire;  provided,  however,  that this  Section
7.5(a) shall not prevent  advertisements,  solicitations,  position  listings or
notices of employment  opportunities that are published or made available to the
public or hiring of personnel responding thereto.

     (b) For a period of three (3) years from the Closing  Date,  Seller and the

Seller on the Closing Date.

     7.6 Employee Matters.

responsibility  for  contributions  to, or any liability  under or in connection

liable for  continuation  coverage  (including  any  penalties,  excise taxes or
interest resulting from the failure to provide  continuation  coverage) required
by Section 4980B of the Code with respect to (i) qualifying  events  incurred by
any Business Employee who does not become an employee of Buyer on or immediately
following the Closing (or covered dependents or qualified  beneficiaries of such
employee),  and (ii) any qualifying  events which occur on or before the Closing
Date  incurred by any  Business  Employee who becomes an employee of Buyer on or
immediately  following  the Closing  Date (or covered  dependents  or  qualified
beneficiaries  of such  employee).  Buyer  will in no  event be  deemed  to be a
successor   employer  (within  the  meaning  of  Treasury   Regulation   Section
54.4980B-2) of Seller


                                       28



for purposes of applying the  provisions of Section 4980B of the Code  following
the Closing with respect to any current or former employee of Seller.

     (b) Buyer shall, as of the Closing Date,  offer employment to those Closing
Date  Employees  listed on Schedule  7.6(b).  Any such Closing Date Employee who
accepts  Buyer's offer of employment  and who,  within seven days of the Closing
Date,  commences  employment with Buyer by reporting for work and being actively
employed  by  Buyer  for at  least  one  day  is  hereinafter  referred  to as a
"Transferred  Employee."  Buyer  shall  provide  or  cause  to  be  provided  to
Transferred   Employees   compensation  and  benefits  that  are   substantially
comparable, in the aggregate, to the compensation and benefits (exclusive of any
such compensation and benefits  consisting of or based on any equity securities)
provided to them by Seller under the Employee Benefit Plans immediately prior to
the Closing.  Subject to the satisfaction of applicable enrollment requirements,
each Transferred Employee (and his or her eligible spouse or dependents) who, as
of the Closing Date,  participates in Employee Benefit Plans of Seller shall, as
soon  as  administratively   feasible  following  such  Transferred   Employee's
commencement  of  employment  with  Buyer,  become  eligible to  participate  in
employee benefit plans maintained by Buyer for its employees.

     (c) With  respect to any  Transferred  Employee  (including  any  dependent
thereof) who is hospitalized or is on short-term  disability  under any Employee
Benefit Plan on or prior to the Closing Date and who remains  hospitalized or on
short-term  disability  after such date,  Seller shall be responsible for claims
and expenses  incurred both before and after the Closing Date in connection with
such  individual,  to the extent that such claims and expenses are covered by an
Employee Benefit Plan of Seller, until such time (if any) that, in the case of a
Transferred Employee, such individual commences full-time employment with Buyer,
and, in the case of a dependent  of a  Transferred  Employee,  such  dependent's
hospitalization has terminated.

     (d) Seller shall be responsible for, and Buyer does not and will not assume
any liability (direct or indirect, contingent or otherwise) that may arise under
or in  connection  with any state or local law similar to the Worker  Adjustment
and Retraining  Notification Act, 29 U.S.  Stat.ss.2010 et. seq., as a result of
