Date, the taxes  reflected on the Closing  Balance Sheet shall be based upon the
actual taxes for the  preceding  year for which actual tax amounts are available
and such taxes  shall be  reprobated  upon  request of either  party made within

Agreement,  and Buyer shall have no liability for such claims. Buyer agrees with
the Seller  that Buyer is solely  responsible  for any and all claims for injury

     Section l0. Non-CompetitiOn.  The Seller, in order to induce Buyer to enter
into this  Agreement,  expressly  covenants and agrees that for a period of five
years  from and  after the  Closing  Date,  neither  the  Seller  nor any of its
subsidiaries will directly or indirectly,  own, manage,  operate, join, control,
or participate in or be connected  with any business,  individual,  partnership,
firm or corporation,  which is at the time engaged,  wholly or partly, in any of
the businesses  engaged in by the Software  Division,  Computer  Training Center
Division, and Market Street Division on the Closing Date.

     The  Seller  may own an  aggregate  of not more  than five  percent  of the
outstanding stock of any class of any corporation  engaged in any such business,
if such stock is listed on a national securities exchange or regularly traded in
the  over-the-counter  market by a member  of a  national  securities  exchange,
without  violating the  provisions of this Section 10,  provided that the Seller
does not have the power to control or direct the  management  or affairs of such
corporation  and is not  otherwise  associated  with it.  The  Seller  expressly
covenants  and agrees  that the remedy at law for any breach of this  Section 10
will be inadequate  and that, in addition to any other  remedies Buyer may have,
Buyer shall be entitled to temporary and permanent injunctive relief without the
necessity  of  proving  actual  damage.  To the  extent  that  any  part of this
provision  may be  invalid,  illegal  or  unenforceable  for any  reason,  it is
intended  that such part  shall be  enforceable  to the  extent  that a court of
competent  jurisdiction  shall determine that such part if more limited in scope
would  have  been  enforceable  and such  part  shall be  deemed to have been so
written and the remaining parts shall as written be effective and enforceable in
all  events.  The Seller and Buyer  agree that the total  consideration  for the
covenant contained in this Section 10 is $50,000.

     Section 11. Post Closing Covenants of Buyer.

such Liabilities have been paid, satisfied or discharged by Buyer.

     11.2.  Availability  of  Records.  After  the  Closing,  Buyer  shall  make
available  to the  Seller as  reasonably  requested  by either the Seller or any
taxing authority all information,  records or documents  relating to the Assets,
the  personnel  records  referred  to in Section 5.4 or the  Software  Division,
Computer  Training Center  Division,  and Market Street Division for all periods
prior to Closing and shall preserve all such information,  records and documents
until the later of six years

                                       22



after the Closing or the expiration of all statutes of limitations or extensions
thereof applicable to the Seller. Buyer shall also make available to the Seller,
as reasonably  requested by the Seller,  personnel  responsible for preparing or
maintaining  information,  records and  documents,  both in connection  with tax
matters as well as litigation.  Prior to destroying  any records  related to the
Software Division, Computer Training Center Division, and Market Street Division
prior to the  Closing  Date,  Buyer  shall  notify  the  Seller of its intent to
destroy  such  records,  and Buyer  will  permit  the  Seller to retain any such
records. With respect to any claims which are the Seller's  responsibility under
Section 8.3, Buyer shall render all reasonable  assistance  which the Seller may
request in defending such claim and shall make available to the Seller technical
personnel most knowledgeable about the product in question.

     11.3.  Use of Trade or  Service  Marks.  Buyer  shall not use or permit its
distributors to use the name "ProtoSource." Any other corporate trade or service
marks owned or used by the Seller or any of its  subsidiaries may not be used by
the Buyer unless (i) such marks or names are  included in the Assets,  (ii) such
use is  permitted  in  writing  by the  Seller or (iii)  such marks or names are
located on the Assets,  in which case Buyer may use, and permit its distributors
to use,  such marks or names for a period of six months  following  the  Closing
Date.

     Section 12. Statement of Source and Use of Funds.

     12.1.Statement of Source and Use of Funds. On the Closing Date, Seller will
present  to  Buyer a  Statement  of  Source  and Use of  Funds  of the  Software
Division,  Computer  Training Center Division,  and Market Street Division as of
the Closing Date (the "Statement of Source and Use of Funds").  The Statement of
Source and Use of Funds shall be prepared by Seller with the assistance of Buyer
if  necessary,  from the Seller's  books and records of the  Software  Division,
Computer Training Center Division,  and Market Street Division. The Statement of
Source  and Use of Funds  shall be  prepared  on a basis  consistent  with those
practices applied in preparation of the Cash Flow Statement. All normal year-end
closing  adjustments,  including  accruals of expenses through the Closing Date,
will be made in the  Statement of Source and Use of Funds as if the Closing Date
were at fiscal year end.

     12.2. Resolution. In the event the Buyer in good faith disputes any amounts
in the  Statement of Source and Use of Funds,  determined as provided in Section
12.1 above, the party disputing such amount shall give written notice thereof to
the other party  within 30 days of the date Buyer had  proposed  adjustments  as
provided in Section 12.1. The parties shall then attempt to resolve such dispute
amicably  within 30 days after the date of such notice,  or within any extension
of such period agreed to in

                                       23



writing by the Seller and Buyer.  If the matter is not  resolved,  then as their
exclusive  method of resolving  the  dispute,  the Seller and Buyer shall select
within 14 days after said  30-day  period a  nationally  recognized  independent
public accounting firm other than the Seller's  independent public  accountants,
to  resolve  such  dispute  or, if the Seller and Buyer are unable to agree upon
such accounting  firm within said 14-day period,  then shall thereupon be deemed
selected by both parties such accounting firm as designated by the Seller, which
shall render their determination within 30 days of receiving the work papers and
preliminary  opinion other than the Seller's  independent public accountants and
any written  challenges  thereto by Buyer or the Seller. The fees and charges of
any such  accounting  firm so  selected  shall be born  equally by the Buyer and
Seller. Such accounting firm's decision as to the Statement of Source and Use of
Funds shall be final and binding on both parties.

     12.3.  Settlement  of  Accounts.  The net  change  in cash of the  Software
Division, Computer Training Center Division, and Market Street Division as shown
on the  Statement of Source and Use of Funds will be adjusted  against the Total
Cash  Investment  (attached  hereto as Exhibit B) The Seller shall pay Buyer the
adjusted amount.

     Section 13. Indemnification, Survival and Termination.

     13.1.  Indemnification  by the Seller.  The Seller  agrees to indemnify and
hold  harmless  the Buyer and its  affiliates  at all times,  and against and in
respect of all losses,  liabilities,  costs and expenses  (including  reasonable
attorneys'  fees)  which  arise  out  of or  are  based  on  any  breach  of the
representations,  warranties,  covenants  and  agreements of Seller set forth in
this Agreement, the operation of the business of the Software Division, Computer
Training Center  Division,  and Market Street Division prior to the Closing Date
or the noncompliance  with any applicable bulk sales or similar laws, insofar as
such losses,  liabilities,  costs and expenses (including  reasonable attorney's
fees) exceed in the aggregate $50,000.

     Buyer shall promptly  notify the Seller in writing of all matters which may
give rise to the right to indemnification  hereunder,  but the failure to notify
Seller shall not relieve  Buyer from any  liability it may have to Seller to the
extent Seller is not  prejudiced  as a result of such failure.  The Seller shall
have the  right,  with the  consent  of Buyer  which  shall not be  unreasonably
withheld, to settle all indemnifiable matters related to claims by third parties
which are  susceptible to being settled,  and to defend  (without the consent of
Buyer) through counsel of its own choosing, at its own expense, any action which
may be brought by a third party in connection therewith, provided, however, that
Buyer shall have the right to have its

                                       24



counsel  participate  fully in such  defense at its own  expense.  Buyer and the
Seller shall keep each other informed of all settlement  negotiatiOns with third
parties and of the progress of any litigation with third parties,  Buyer and the
Seller  shall  permit  each other  reasonable  access to books and  records  and
otherwise  cooperate  with all  reasonable  requests of each other in connection
with any matter or claim for indemnification by a third party.

     13.2.  Indemnification  by Buyer.  The Buyer agrees to  indemnify  and hold
harmless the Seller and its affiliates at all times,  and against and in respect
of all losses,  liabilities,costs  and expenses (including reasonable attorneys"
fees)  which  arise  out of or are based on any  breach of the  representations,
warranties, covenants and agreements of Buyer set forth in this Agreement or the
operation of the business of the Software  Division,  Computer  Training  Center
Division,  and Market  Street  Division  after the Closing  Date insofar as such
losses,  liabilities,  costs and expenses (including reasonable attorney's fees)
exceed in the aggregate $10,000.

     Seller shall promptly  notify the Buyer in writing of all matters which may
give rise to the right to indemnification  hereunder,  but the failure to notify
Buyer shall not relieve  Seller from any  liability  it may have to Buyer to the
extent Buyer is not prejudiced as a result of such failure. The Buyer shall have
the right, with the consent of Seller which shall not be unreasonably  withheld,
to settle all indemnifiable matters related to claims by third parties which are
susceptible  to being  settled,  and to defend  (without  the consent of Seller)
through counsel of its own choosing, at its own expense, any action which may be
brought by a third party in connection therewith, provided, however, that Seller
shall have the right to have its counsel  participate  fully in such  defense at
its own  expense.  Buyer and the Seller  shall keep each other  informed  of all
settlement negotiations with third parties and of the progress of any litigation
with third parties,  and Buyer and the Seller shall permit each other reasonable
access to books and records and otherwise cooperate with all reasonable requests
of each other in connection  with any matter or claim for  indemnification  by a
third party.

     13.3.  Survival.  The  representations  and  warranties  contained  in this
Agreement shall survive the Closing for a period of five years at which the time
they shall expire.  No claim may be made based upon an alleged  breach of any of
such  representations  or  warranties  whether  for  indemnification  in respect
thereof or otherwise, unless written notice of such claim, in reasonable detail,
is given to Buyer,  or to the Seller,  as the case may be, within said five year
period.

     13.4.  Termination.  This Agreement may be terminated any time prior to the
Closing Date:
