or liability  whatsoever of the Seller or relating to any of the Acquired Assets
(all such  obligations  and  liabilities  being,  collectively,  the  "Unassumed
Liabilities").

               (b) The term "Unassumed  Liabilities" includes, and the Purchaser

               1.3.  Purchase  Price.  (a) The  purchase  price  (the  "Purchase
Price") for the Acquired  Assets and the  agreement not to compete of the Seller
set forth in  Section  3.4 shall be cash in the amount of  $2,910,000,  of which
$2,900,000 is payable as  consideration  for the Acquired  Assets and $10,000 is
payable to the Seller as  consideration  for its agreement  not to compete.  The
Shareholders  shall be  compensated  for their  agreement  not to compete as set
forth in Section 3.4.  The  Purchaser  shall pay the Purchase  Price at Closing.
Such  payment  shall be made by  certified  or bank check or checks,  or, at the
option of the Seller, by wire transfer to an account of the Seller designated to
the  Purchaser.  The Seller  shall  provide  the  Purchaser  with  notice of the
exercise of such option and the  designation of such account,  such notice to be
delivered not less than three business days before the Closing.

               (b) The Seller and the Purchaser agree that the allocation  among
the  Acquired  Assets of the  Purchase  Price  will be as set forth on  Schedule
1.3(b),  which is in  accordance  with the  guidelines  of the Internal  Revenue
Service (the "IRS").  The Seller and the Purchaser agree that such allocation is
fair and  equitable.  The parties agree to be bound by such  allocation  for all
purposes,  including for purposes of all Federal,  state,  local and foreign tax
returns filed by them subsequent to the Closing Date, the  determination  by the
Seller  of  taxable  gain or loss on the  sale of the  Acquired  Assets  and the
determination by the Purchaser of its tax basis in the Acquired Assets.

               1.4. Closing. The closing (the "Closing") for the consummation of
the transactions  contemplated by this Agreement shall take place at the offices
of Howard, Darby & Levin, 1330 Avenue of the Americas, New York, New York 10019,
or such other place as the Seller and the Purchaser  shall agree,  at 10:00 a.m.
(Eastern  time  zone)  on the  later of May 8,  1996  and the date on which  all
conditions set forth in Article IV shall have been satisfied or waived,  or such
other date and time agreed to by the Seller and the Purchaser  (such date of the
Closing being hereinafter called the "Closing Date").

               1.5. Instruments of Conveyance and Transfer.  At the Closing, the
Seller  shall  deliver  to the  Purchaser  such  bills  of  sale,  endorsements,
assignments and other  instruments of transfer,  conveyance and assignment (in a
form  satisfactory to the Seller and the Purchaser) as shall be necessary in the
reasonable judgment of the Purchaser to transfer, convey and assign the Acquired
Assets to the Purchaser.

               1.6.  Post-Closing  Assurances.  The Seller and the  Shareholders
shall pay to the  Purchaser any amounts which shall be received by the Seller or
any Shareholder  after the Closing Date which constitute  Acquired  Assets.  The
Seller and the  Shareholders  shall, at any time and from time to time after the
Closing  Date,  upon the  reasonable  request  of the  Purchaser,  do,  execute,
acknowledge,  deliver  and file,  or cause to be done,  executed,  acknowledged,
delivered  or filed,  all such  further  acts,  deeds,  transfers,  conveyances,
assignments  or  assurances  as  may  be  reasonably  required  for  the  better
transferring,  conveying,  assigning and assuring to the  Purchaser,  or for the
aiding and  assisting in the reducing to  possession by the Purchaser of, any of
the  Acquired  Assets.  In  connection  with the  foregoing,  from and after the
Closing  Date,  the  Purchaser  shall have the right and  authority  to endorse,
without  recourse,  the name of the  Seller on any check or  similar  negotiable
instrument received by the Purchaser  constituting  Acquired Assets transferred,
conveyed and assigned to the Purchaser hereunder.


                                       -3-





               1.7. Assignment of Contracts, Rights. Notwithstanding anything to
the contrary contained in this Agreement, this Agreement shall not constitute an
agreement  or attempt to  transfer,  sublease or assign any  contract,  license,
lease,  sales order,  purchase order or other agreement or any claim or right of
any benefit  arising  thereunder  or  resulting  therefrom  or any  governmental
permit,  license,  approval,  registration  or  certificate  of  occupancy if an
attempted transfer,  sublease or assignment thereof,  without the consent of any
other party thereto,  would  constitute a breach thereof or in any way adversely
affect the Purchaser's rights to receive the benefits thereunder.

applied on a basis  consistent  with prior  periods and are true,  accurate  and
complete.  The  balance  sheets of the Seller as at the dates set forth  present

Agreement,  all financial statements referred to in this paragraph shall include

               (ii) There were no liabilities or obligations  (whether absolute,
accrued,  contingent or otherwise,  and whether due or to become due) in respect
of the Business or the Acquired  Assets which were required to be, in accordance
with  GAAP,  and were not shown or  provided  for on the  balance  sheets of the
Seller  to  which  such  liabilities  or  obligations   related.   All  reserves
established  by the Seller for the Business are reflected on the balance  sheets
of the  Seller and are  adequate  and there are no loss  contingencies  that are
required to be accrued by Statement of  Financial  Accounting

               (f) Absence of Changes.  Except as set forth in Schedule  2.1(f),

consistent with past practice.

               (g) Assets,  Property and Related Matters; Real Property. (i) The
Seller has good title to, or a valid leasehold  interest in, as applicable,  all
of the Acquired Assets, free and clear of all mortgages, liens, pledges, charges
or  encumbrances  of  any  kind.  The  Acquired  Assets  constitute  all  of the
properties, interests, assets and rights held for use or used in connection with
the  Business  and  constitute  all those  necessary  to continue to operate the
Business consistent with current and historical practice.

               (ii) The Seller does not own any real property in connection with
the Business.  The real property leased in connection with the Business consists
only of the leased property  located at 314 South K Street,  Tacoma,  Washington
(the "Tacoma  Property")  and the real  property  located at 5201 S.W.  Westgate

Property and all personal  property  leases.  With respect to property leased by
the  Seller in  connection  with the  Business,  (I) the Seller is the owner and
holder of all the  leasehold  interests  and estates  purported to be granted by
such  leases,  (II) to the  knowledge  of the Seller and the  Shareholders,  all
leases  to  which  the  Seller  is a party  are in full  force  and  effect  and
constitute valid and binding  obligations of the Seller and, to the knowledge of
the Seller and the  Shareholders,  of the other parties thereto,  enforceable in
accordance  with  their  terms and (III) the Seller  has made  available  to the
Purchaser  true and  complete  copies  of all  leases  referred  to in  Schedule
2.1(g)(ii). To the knowledge of the Seller and the Shareholders, there exists no
default,  or any event which upon notice or the passage of time, or both,  would
give rise to any  default,  in the  performance  by the  Seller or by any lessor
under any lease.  The Seller has not, and to the knowledge of the Seller and the
Shareholders,  no other person has,  granted any oral or written right to anyone
other  than the  Seller  to  lease,  sublease  or  otherwise  occupy  any of the
properties  described in Schedule  2.1(g)(ii)  through the end of the applicable
lease periods.

               (iii) To the  knowledge of the Seller and the  Shareholders,  the
Seller's use of the Tacoma  Property and the Portland  Property does not violate
any restrictive  covenants and conforms to applicable  Federal,  state and local
laws and regulations. No condemnation proceeding is pending or, to the knowledge
of the Seller or any Shareholder,  threatened which would preclude or impair the
use of the Tacoma  Property or the Portland  Property by the Seller for the uses
for which they are intended.

                                      -6-



Property")  owned,  licensed or used in the  Business.  To the  knowledge of the
Seller and the Shareholders, no Intellectual Property infringes any rights owned
or held by any other  person.  There is no pending or, to the  knowledge  of the
Seller and the Shareholders,  threatened claim or litigation  against the Seller
contesting its right to use any Intellectual  Property.  To the knowledge of the
Seller and the Shareholders, no person is infringing the rights of the Seller in
any Intellectual  Property. To the knowledge of the Seller and the Shareholders,
no product or service sold by the Seller violates or infringes any  intellectual
property  right  owned or held by any  other  person.  To the  knowledge  of the
Seller, in the case of commercially  available  "shrink-wrap"  software programs
(such as Lotus  1-2-3),  neither the Seller nor any of its employees has made or
is using any unauthorized  copies of any such software  programs at any location
of the Business.

knowledge of the Seller and the Shareholders, the Seller is not in default under

after the date of the  Closing,  for any  reason  whatsoever,  (i)  directly  or

                                      -13-



such  breach.  Nothing  contained  in this  paragraph  (c) or  elsewhere in this
Agreement  shall be  construed  as  prohibiting  the  non-breaching  party  from
pursuing  any  other  remedies  available  at law or equity  for such  breach or
threatened  breach  of  this  Agreement  nor  limiting  the  amount  of  damages
recoverable  in the event of a breach or  threatened  breach by any party of the

               6.7.  Benefits of Agreement.  All of the terms and  provisions of
this  Agreement  shall be binding  upon and inure to the  benefit of the parties
hereto and their  respective  successors and assigns.  This Agreement is for the

provision of this Agreement shall be adjudicated to be invalid or unenforceable,
such  provision  shall be deemed  amended to delete  therefrom  the portion thus
adjudicated  to be invalid or  unenforceable,  such  deletion to apply only with
respect to the operation of such  provision in the  particular  jurisdiction  in
which such adjudication is made.

               6.11.  Attorney Fees and Costs;  Remedies for  Misrepresentation.

other equitable relief, the prevailing party in such Action shall be entitled to
recover  reasonable  attorney  fees  and  costs  incurred  in  such  action,  as
determined by the trial court. In the event of any appeals from the Action,  the
prevailing party shall be entitled to recover their reasonable attorney fees and
costs  incurred in such  appeals,  as determined  by the  appropriate  appellate
courts.  The term "costs"  shall  include,  in addition to  statutory  costs and
disbursements,  all  costs  associated  with the  initial  investigation  of and
determination  whether to  commence  an Action,  and all costs  associated  with
discovery  depositions,  witness fees (expert and otherwise),  and out-of-pocket
costs  incurred by the  prevailing  party on the  prosecution  or defense of the
Action.  For the purpose of this section,  the term "Action"  shall be deemed to
include  any   proceeding   commenced   in  any  court  of  general  or  limited
jurisdiction, including any proceeding commenced in the bankruptcy courts of the
United States.



                                      -21-

Action arising out of any misrepresentation (other than one due to actual fraud)
or breach of warranty,  in violation of Sections 2.1 or 2.2 herein, shall be the
recovery of the direct economic  damages to such party,  if any,  arising out of
such misrepresentation or breach. None of the parties hereto shall be liable for
any indirect or consequential damages as a result of such a misrepresentation or
breach of warranty.
