Item 2. Acquisition or Disposition of Assets.

         On  March  3,  1997,   OrthoLogic   Corp.,   a   Delaware   corporation
("OrthoLogic"),  through Toronto Medical Orthopaedics Ltd., a Canada corporation
and its  wholly-owned  subsidiary,  consummated its acquisition of substantially
all of the assets and business and assumed  substantially all of the liabilities
of Toronto  Medical Corp.,  an Ontario  corporation  ("Toronto"),  pursuant to a
Purchase and Sale Agreement (the "Agreement")  dated as of December 30, 1996, as
amended,  which is filed as an exhibit to this report.  As  contemplated  by the
Agreement,  OrthoLogic contemporaneously acquired the assets and assumed certain
liabilities  of  Toronto's  United  States  subsidiaries.   OrthoLogic  paid  an
aggregate  purchase  price of  approximately  $4,000,000  in cash  plus  assumed
liabilities from existing corporate resources.

         The  acquisition  transaction  was  negotiated at arm's length  between
OrthoLogic  and  Toronto.  Prior  to the  acquisition,  none  of the  directors,
officers or associates of Toronto,  or their affiliates,  were or are affiliated
with  OrthoLogic,   its  affiliates,   its  directors  and  officers  and  their
associates.  OrthoLogic  is  accounting  for the  acquisition  of  Toronto  as a
purchase.  OrthoLogic  is in the process of  evaluating  the current  status and
future integration of the operations,  personnel and facilities of Toronto,  and
is planning on closing certain  facilities and terminating or relocating certain
employees.  The  costs  related  to these  activities  have not been  estimated.
Accordingly, OrthoLogic cannot determine or allocate the total purchase price at
this time.

         Toronto's  principal  business  is  the  manufacturing,  marketing  and
distribution  of  orthopaedic  rehabilitation  products,   including  continuous
passive motion ("CPM") devices.

Item 7. Financial Statements and Exhibits.

         (a)      Financial Statements of Businesses Acquired.
         (b)      Pro forma Financial Information.

         At the time of filing this report on Form 8-K, it is  impracticable  to
provide the financial statements and pro forma financial information required by
Item 7 of Form 8-K. The required  financial  statements and pro forma  financial
information  will be filed  as soon as  practicable,  but no later  than 60 days
after this report on Form 8-K must be filed.

         (c)      Exhibits.  See the Exhibit Index, which is incorporated herein
by reference, immediately following the Signature page to this Report.

at the Closing, in accordance with the Plan of Reorganization, in payment of the
purchase of the US Purchased Assets and the Purchased Assets, via bank cashier's
check or wire transfer. At the Closing, Seller shall refund to Buyer the Deposit
(without interest) and pay to Buyer any Accrued
                                        9
<PAGE>
Employee  Benefits  payable as  contemplated  in Section  2.8(a) hereof via bank
cashier's check or wire transfer.

         2.3 Adjustment to Purchase Price.

                  (a)  Delivery of December  Statements.  No later than ten (10)
business days prior to the Closing  Date,  the Seller shall deliver to the Buyer
unaudited  consolidated  financial statements of the Business as at December 31,
1996 (the "December 1996 Statements").

                  (b)  Signing  Adjustment.   If  the  aggregate  value  of  the
Purchased  Assets and the US Purchased  Assets less the  aggregate  value of the
Assumed  Liabilities  and the US  Assumed  Liabilities  (the "Net  Book  Value")
calculated on the basis of the December  1996  Statements  (the  "Signing  NBV")
differs  from the Net Book  Value  calculated  on the basis of the  August  1996
Financial  Statements  (the  "Original  NBV") the Purchase  Price payable by the
Buyer as at the Closing Date will be adjusted in the following manner:

                           (i) if the  Original  NBV is greater than the Signing
         NBV,  the  Purchase  Price will be  decreased by an amount equal to the
         amount by which the Original NBV exceeds the Signing NBV; and

                           (ii) if the  Original  NBV is less  than the  Signing
         NBV,  the  Purchase  Price will be  increased by an amount equal to the
         amount by which the Original NBV is less than the Signing NBV.

                  (c) Closing  Adjustment.  If the Net Book Value as at December
31, 1996 set forth in the  Business  Plan (the "Base NBV")  differs from the Net
Book Value as at the Closing Date projected in the Business Plan (the "Projected
NBV"),  the  Purchase  Price  payable by the Buyer on the  Closing  Date will be
adjusted in the following manner:

                           (i) if the  Projected  NBV is  greater  than the Base
         NBV,  the  Purchase  Price will be  increased by an amount equal to the
         amount by which the Projected NBV exceeds the Base NBV; and

                           (ii) if the  Projected NBV is less than the Base NBV,
         the  Purchase  Price will be decreased by an amount equal to the amount
         by which the Projected NBV is less than the Base NBV.

                  For purposes of calculating  the Projected NBV, if the Closing
Date  does not  occur on the last  business  day of a month,  the net  operating
profit or loss for the Business  projected  in the Business  Plan for such month
will be prorated  based upon the number of business  days which have occurred in
such month to the Closing Date.

                  (d) Bankruptcy  Adjustment.  If the implementation of the Plan
of  Reorganization,  as amended,  causes a decrease or increase in the aggregate
value of the US
                                       10
<PAGE>
Purchased Assets or US Assumed Liabilities,  the Purchase Price will be adjusted
in the following manner:

                           (i)  if  the  aggregate   value  of  the  US  Assumed
         Liabilities  is  decreased or the  aggregate  value of the US Purchased
         Assets is increased in connection with the  implementation  of the Plan
         of  Reorganization,  the Purchase  Price will be increased by an amount
         equal to the amount of such decrease or increase; and

                           (ii)  if  the  aggregate  value  of  the  US  Assumed
         Liabilities  is  increased or the  aggregate  value of the US Purchased
         Assets is decreased in connection with the  implementation  of the Plan
         of  Reorganization,  the Purchase  Price will be decreased by an amount
         equal to the amount of such increase or decrease.

         Not later than five (5) business days prior to the Closing Date, Seller
shall provide Buyer with  financial  statements  setting forth all increases and
decreases  in the  aggregate  value of the US  Purchased  Assets  or US  Assumed
Liabilities in connection with the implementation of the Plan of Reorganization.

                  (e) Extraordinary Item Adjustment.

                           (i) If the December  1996  Statements or the Business
         Plan  either   excluded  or   inaccurately   made   provision  for  any
         extraordinary,    non-operational   or   non-business   related   items
         (collectively  the  "Extraordinary  Items") set out on Schedule  2.3(e)
         attached  hereto,  adjustments will be made between Buyer and Seller to
         the  Purchase  Price based upon the actual  results  realized by either
         Buyer,  TMI  or  USORTHO  in  respect  of  such  Extraordinary   Items.
         Adjustments for Extraordinary Items will be made on Closing, in respect
         of  those  Extraordinary  Items  for  which  actual  results  are  then
         available,  and  subsequent to the Closing on a monthly basis within 10
         business days from the end of each month based upon the actual  results
         of Extraordinary  Items realized during such month. Not later than five
         business days prior to the Closing Date, or five business days from the
         end of each month after the Closing  Date,  Seller shall  provide Buyer
         with  a  statement  (an   "Adjustment   Statement")   setting  out  the
         adjustments  to the Purchase  Price which are to be made between  Buyer
         and Seller in  respect  of  Extraordinary  Items.  Notwithstanding  the
         foregoing,  any Agent Litigation  recovery shall be applied as follows:
         (i) first, to Buyer, on account of any Purchased Assets or US Purchased
         Assets to the extent they are included in the December 1996 Statements;
         (ii) second,  to reimburse  Buyer or Seller for  reasonable  attorneys'
         fees incurred in connection  with such recovery;  and (iii) third,  the
         remainder divided equally between Buyer and Seller.

                           (ii)  Seller  shall,  prior  to the  Closing,  obtain
         insurance  coverage for Product  Liability  Matters  arising  after the
         Closing  Date,  fifty  percent  of  the  cost  of  which  will  be  the
         responsibility  of Buyer and fifty percent of the cost of which will be
         the
                                       11
<PAGE>
         responsibility  of Seller.  The Purchase  Price will be increased in an
         amount equal to the Buyer's portion of the cost of such insurance.

                  (f) Closing  Value.  Not later than thirty (30)  business days
after the  Closing  Date,  the  Seller  shall  deliver  to the  Buyer  unaudited
consolidated  financial  statements of the Business for the period from the date
of signing of this Agreement to the Closing Date (the "Closing Statements").  If
the Net Book Value for the Closing Date  calculated  on the basis of the Closing
Statements  differs from the  Projected  NBV the Purchase  Price  payable by the
Buyer on the Closing Date will not be adjusted.

                  (g) Aggregation of Adjustments. At the Closing the adjustments
to the Purchase Price calculated  pursuant to subsections (b), (c), (d), and (e)
of this Section 2.3 shall be  aggregated as of the Closing Date. If the positive
adjustments  to the Purchase  Price differ from the negative  adjustments to the
Purchase  Price by an  amount  equal to or  greater  than  $100,000.00  US,  the
following payments shall be made by the following parties no later than ten (10)
business days following the Closing Date:

                           (i) If the positive adjustments to the Purchase Price
         exceed the negative  adjustments to the Purchase Price, Buyer shall pay
         the positive  difference,  to the extent it exceeds  $100,000.00 US, to
         Seller via bank cashier's check or wire transfer.

                           (ii)  If the  negative  adjustments  to the  Purchase
         Price exceed the positive adjustments to the Purchase Price, Seller or,
         at Seller's  option,  TMI,  shall pay the negative  difference,  to the
         extent it exceeds  $100,000.00 US, to Buyer via bank cashier's check or
         wire transfer.

                  (h) Adjustment Threshold.  The $100,000.00 threshold described
in Section 2.3(g) above shall continue to be aggregated to include,  in addition
to  adjustments  made  pursuant to  subsections  (b),  (c),  (d) and (e) of this
Section 2.3 as at the Closing Date,  adjustments  made subsequent to the Closing
Date  pursuant to  subsection  (e) of this Section  2.3, and Damages  calculated
pursuant  to Article  VIII  hereto.  Any excess  payments  made by either  party
because of the  ongoing  adjustment  of the  threshold  shall be refunded to the
other party.

                  (i) Preparation of Statements.  Notwithstanding the foregoing,
the Buyer may, at its own expense,  have its  employees  or auditors  review the
working  papers  or  other  background  materials  used  to  prepare  any of the
statements  described  in this Section 2.3, and the Seller shall ensure that the
Buyer and its employees  and agents have full access to such working  papers and
other background  materials.  Any disagreement as to the statements described in
this  Section  2.3 which  cannot be settled by the  parties  shall be settled by
arbitration in accordance with Section 8.19. Seller and its employees and agents
will have access to and use of, at no cost, the Retained  Employees  (including,
without limitation,  Christopher Pigott) and the computer systems and Records of
the  Business  after  the  Closing  Date in order  to  complete  the  statements
described in this Section 2.3, the  calculation  and  adjustment of the Purchase
Price and year-end financial statements in all respects.

         2.4  Allocation  of Purchase  Price.  The  Purchased  Assets and the US
Purchased  Assets  will  be  allocated  as set  forth  in  Section  6.5 of  this
Agreement.

         2.5 Referrals and Deliveries. After the Closing, Seller shall promptly:

                  (a) Deliver to Buyer,  in the form  received with the addition
of any required  endorsements  by Seller,  any cash,  checks,  or other payments
received after the Closing Date by Seller relating to the Accounts as well as to
the conduct of the Business after the Closing;

                  (b) Refer to Buyer any and all  inquiries  or purchase  orders
from customers or suppliers of Seller or other persons relating to the Business;
and

                  (c) Cooperate  with Buyer in setting up a "lock box" procedure
for collection of Accounts, if Buyer so elects.

         2.6 Risk of Loss.  Risk of loss with  respect to the  Purchased  Assets
shall  remain  with  Seller  until the  Closing and shall pass to Buyer upon the
Closing.

         2.7 Noncompetition; Confidentiality.

                  (a) Subject to the Closing,  and as an  inducement to Buyer to
execute this Agreement and complete the transactions contemplated hereby, and in
order to preserve  the goodwill  associated  with the  Business  being  acquired
pursuant to this Agreement, Seller hereby covenants and agrees that for a period
of five (5) years from and after the  Closing  Date,  it will not,  directly  or
indirectly, within the Territory described below:

                           (i) engage  in, continue in or carry on  any business
which  competes  with the Business or the Buyer's  Business or is  substantially
similar thereto,  including owning or controlling any financial  interest in any
corporation,  partnership,  firm or other form of business organization which is
so engaged;

                           (ii) consult  with,  advise  or  assist  in  any way,
whether or not for consideration,  any corporation,  partnership,  firm or other
business  organization  which is now or  becomes  a  competitor  of Buyer in any
aspect with respect to the Business or the Buyer's Business  including,  but not
limited,to,  advertising  or  otherwise  endorsing  the  products  of  any  such
competitor; soliciting customers or otherwise serving as an intermediary for any
such  competitor;  loaning  money  or  rendering  any  other  form of  financial
assistance to or engaging in any similar form of business  transaction  with any
such  competitor  provided,  however,  that  Seller  shall not be  prevented  or
restricted from either leasing or selling the Premises to any such competitor of
Buyer after Buyer has ceased occupying the premises pursuant to the Lease;

                           (iii) hire, offer  to hire, or solicit for employment
any employee of Buyer, without the prior consent of Buyer, until such person has
been separated from employment by Buyer for at least one year; or
                                       13
<PAGE>

                           (iv) engage in any practice the  purpose  of which is
to  evade  the  provisions  of  this  covenant  not  to  compete  or  to  commit
intentionally  any  act  which  adversely  affects  the  Business,  the  Buyer's
Business, the Purchased Assets, or the Assumed Liabilities;  provided,  however,
the foregoing  prohibition does not extend to passive  ownership of less than 1%
of the  outstanding  stock of any entity whose stock is traded on an established
stock exchange or quoted on NASDAQ. For purposes hereof,  "Territory" is defined
as any  county  or  similar  geographic  subdivision  in which  Seller  or Buyer
conducted its business as of the date of this Agreement. The parties intend that
this noncompete covenant shall be construed as separate covenants,  one for each
county and subdivision to which the covenant applies.  The parties agree further
that Buyer may sell, assign or otherwise  transfer this covenant not to compete,
in whole or in part, to any person,  corporation,  firm or entity that purchases
all or part of the Buyer's  business or the  Business  or the  Purchased  Assets
being  acquired  by  Buyer  hereunder.   In  the  event  a  court  of  competent
jurisdiction  determines that the provisions of this covenant not to compete are
excessively broad as to duration,  geographic scope or activity, it is expressly
agreed  that  this  covenant  not to  compete  shall  be  construed  so that the
remaining  provisions shall not be affected,  but shall remain in full force and
effect,  and any such over broad  provisions  shall be deemed,  without  further
action on the part of any person,  to be modified,  amended and/or limited,  but
only to the extent  necessary to render the same valid and  enforceable  in such
jurisdiction.

                  (b) Seller  acknowledges  that: (i) the Business  connections,
customers, customer lists, marketing, production, sales techniques,  procedures,
operations, and other Intangible Assets and aspects of the Business which are to
be acquired by Buyer hereunder have been established and maintained by Seller at
great  expense,  have  been  protected  as  confidential  information  and trade
secrets, and are of great value to Buyer; and (ii) Buyer would suffer great loss
and injury if Seller would disclose this information or use it in any way to the
detriment of Buyer. Therefore,  Seller shall not, directly or indirectly, use or
disclose, or cause or allow to be used or disclosed,  to Buyer's detriment,  any
secret, confidential, or proprietary information relating to the Business.

                  (c) After the date  hereof,  Seller  shall use its  reasonable
best efforts,  on behalf of Buyer, to continue amicable  business  relationships
with  Business  customers  and  suppliers.  Seller shall not make or publish any
disparaging remarks about Buyer, the Buyer's business or the Business as long as
Buyer continues the Buyer's business and/or the Business,  and shall not induce,
encourage,  or cause any customer or supplier to terminate  doing  business with
Buyer.

         2.8 Employee Matters.

                  (a) Buyer  shall,  on or before  the  Closing  Date,  offer to
employ Kevin Lunau,  Christopher Pigott and at least seventy-five  percent (75%)
of the remaining employees of Seller, excluding any employees of TMI or USORTHO,
and excluding John Saringer and Jean-Pierre Scheidegger, employed on the Closing
Date (the "Retained  Employees") on terms and conditions of employment including
without limitation,  salary, benefits, position and responsibilities,  which are
no less favorable  than those paid to and/or enjoyed by such Retained  Employees
on the
                                       14
<PAGE>
Closing Date.  Without limiting the generality of the foregoing,  the Buyer will
not offer  employment to either John Saringer or  Jean-Pierre  Scheidegger.  The
Buyer shall provide,  within fifteen (15) days after the date of signing of this
Agreement,  to the Seller a list  identifying  the Retained  Employees,  failing
which the  Retained  Employees  shall  consist  of all  employees  of the Seller
employed on the Closing Date.  Buyer shall recognize the period of employment of
the  Retained  Employees  who  accept  the  Buyer's  offer  of  employment  (the
"Accepting Employees") with Seller up to the Closing Date for all purposes as if
such service had  occurred  with Buyer.  Buyer agrees to assume all  liabilities
associated with the Retained Employees including, without limitation, payment of
any Accrued Employee Benefits (as hereinafter defined) and all costs incurred in
connection with the termination or lay-off of any such employee, and Buyer shall
indemnify  and save  harmless  Seller in  respect of such  assumed  liabilities.
Seller and Buyer  shall  cooperate  to provide an orderly  transfer  for accrued
employee vacation and sick leave benefits (the "Accrued Employee Benefits") from
Seller to Buyer in order to preserve  the  benefits  available  to the  Retained
Employees.  Seller shall prepare a comprehensive  list of such Accrued  Employee
Benefits by  employee  as of the date ten (10) days prior to the  Closing  Date,
shall value such Accrued  Employee  Benefits at the rates of pay in effect as of
such date,  and shall pay Buyer at the  Closing  cash equal to the value of such
Accrued Employee Benefits, for that portion of the Accrued Employee Benefits not
already provided for in the December 1996 Statements or the Business Plan.

                  (b) With respect to  employees of Seller,  TMI and USORTHO who
are not offered continuing  employment with Buyer,  Seller shall provide written
notices to such employees and, Seller, TMI or USORTHO, as the case may be, shall
be  responsible  for all  payments  to said  employees  for wages,  commissions,
bonuses,  vacations,  severance and other similar forms of compensation owing to
or accrued by such employees.

                  (c) Subject to subsections (a) and (b) above,  Buyer shall not
be obligated to Seller or any other party for any  labor-related  obligations or
liabilities  arising out of any person's employment with Seller, TMI and USORTHO
and Seller agrees to satisfy said obligations and/or liabilities.

         2.9 Access to Records.

                  (a) Seller shall permit Buyer, and its attorneys, accountants,
agents and designees,  such access to, and right to copy, all books,  papers and
records of Seller which are not a part of the Purchased  Assets,  from and after
the  Closing  Date hereof as Buyer may deem  necessary  or  desirable.  Any such
examination  shall be at the expense of Buyer,  shall be performed during normal
business  hours at the place where such  records  are  regularly  maintained  by
Seller and shall not unreasonably  interfere with the normal business activities
of Seller. Seller shall notify Buyer at any time within the five (5) year period
after the Closing Date if it intends to destroy any or all of the books, papers,
and records described above, and Buyer shall have the right to review and remove
any of such books, papers and records at Buyer's expense.
                                       15
<PAGE>
                  (b) Buyer shall  preserve any Records in its  possession for a
period of five (5) years from the Closing  Date,  or for such  longer  period as
required by any  applicable  Laws, and shall keep Seller advised at all times of
the location of such  Records.  Buyer shall permit  Seller,  and its  attorneys,
accountants,  agents and  designees,  such  access  to,  and right to copy,  all
Records from and after the Closing  Date hereof as Seller may deem  necessary or
desirable.  Any such  examination  shall be at the  expense of Seller,  shall be
performed  during  normal  business  hours at the place  where the  Records  are
regularly  maintained  by Buyer and shall not  unreasonably  interfere  with the
normal  business  activities  of Buyer.  Buyer shall  notify  Seller at any time
within the five (5) year period  after the Closing Date if it intends to destroy
any or all of the Records,  and Seller shall have the right to review and remove
any of such Records at Seller's expense.

         2.10 Noncompete Agreements. At Closing, Seller shall cause each of John
Saringer, Jean-Pierre Scheidegger and Kevin Lunau to enter into their respective
Noncompete Agreement.

         2.11  Investment  Canada.  Within thirty (30) days of the Closing Date,
Buyer shall make all required filings under the Investment Canada Act. Buyer has
otherwise complied with the requirements of the Investment Canada Act.

         2.12  GST.  On or prior  to the  Closing  Date,  Buyer  shall  become a
registrant for the purposes of the Excise Tax Act (Canada).

acceptable  to Buyer.  Buyer  shall  have the right to  participate,  at its own
expense,  with  respect  to any such  third  party  claim,  demand,  action,  or
proceeding.  In connection with any such third party claim,  demand,  action, or
proceeding,  Buyer and Seller shall  cooperate  with each other and provide each
other with access to relevant  books and  records in their  possession.  No such
third party claim,  demand,  action,  or proceeding shall be settled without the
prior  written  consent of Buyer and Seller.  If a firm written offer is made to
settle any such third party  claim,  demand,  action,  or  proceeding  and Buyer
refuses to consent to such  settlement,  then: (i) Seller shall be excused from,
and Buyer shall be solely  responsible  for,  all further  defense of such third
party claim,  demand,  action, or proceeding;  and (ii) the maximum liability of
Seller relating to such third party claim,  demand,  action, or proceeding shall
be the amount of the proposed settlement if the amount thereafter recovered from
Buyer on such third
                                       35
<PAGE>
party claim,  demand,  action,  or  proceeding is greater than the amount of the
proposed settlement.  With respect to any direct claim, following the receipt of
notice from Buyer of such claim  Seller shall have thirty (30) days to make such
investigation  of the claim as is  considered  necessary or  desirable.  For the
purpose  of such  investigation,  Buyer  shall  make  available  to  Seller  the
information  relied upon by Buyer to substantiate  the claim,  together with all
such other information as Seller may reasonably request. If the parties agree at
or prior to the  expiration  of such  thirty  (30) day period  (or any  mutually
agreed upon extension thereof) to the validity and amount of such claim,  Seller
shall  immediately  pay to Buyer the fully  agreed upon amount of the claim.  If
Buyer and Seller fail to agree on the  validity  and amount of such  claim,  the
matter  shall be  settled  by  arbitration  in  accordance  with  Section  8.19.
Notwithstanding the foregoing, Seller shall not be required to indemnify or save
harmless Buyer in respect of any breach of inaccuracy of any  representation  or
warranty  unless Buyer shall have provided  notice to Seller in accordance  with
this  Section  8.1(b) at or prior to the  expiration  of the period set forth in
Section 8.6.

                  (c) With respect to the  Premises,  Seller  agrees to grant to
Buyer on the Closing Date a mortgage (the  "Buyer's  Mortgage") on the Premises,
for a principal amount which does not exceed 50% of the fair market value of the
Premises at the time the Buyer's  Mortgage  is granted,  to satisfy,  subject to
Section  2.3(h),  any Damages Buyer may suffer in connection  with the indemnity
set out in Section 8.1(a), provided however that Buyer agrees:

                           (i)  to postpone and subordinate the Buyer's Mortgage
from time to time as Seller  shall  request  to one or more  mortgages,  and any
replacements  thereof,  the principal amount of which, in the aggregate,  do not
exceed  50% of the  fair  market  value  of the  Premises  at the  time any such
mortgage is granted; and

                           (ii) that Buyer's  Mortgage  shall be  discharged on,
and shall expire and be of no further force or effect subsequent to, a date (the
"Discharge Date"), which is the earlier of:

                                    (1) two  (2)  years  after the Closing Date;
and

                                    (2) the  date on  which the Premises is sold
by Seller;  provided that Seller  provides to Buyer, in form acceptable to Buyer
acting  reasonably,  security in the form of cash proceeds equal in value to the
principal  amount of the  Buyer's  Mortgage,  such  replacement  security  to be
discharged on, and shall expire and be of no further force and effect subsequent
to, the date set out in (1) above. On the Closing Date,  Buyer shall execute and
deliver a discharge of the Buyer's Mortgage,  in registerable  form, to Seller's
counsel,  which discharge the Seller's counsel is hereby irrevocably  authorized
and directed by Buyer to register against title to the Premises on the Discharge
Date.

                  (d) If the  procedures  set forth in Sections  8.1(b) and 8.19
have been fully completed and satisfied,  and Seller does not immediately pay to
Buyer any amount that, subject to Section 2.3(h), has become payable pursuant to
Section 8.1(a), Buyer shall have the option
                                       36
<PAGE>
recouping  all or any part of such claim by offsetting  such amount  against the
Lease in such order as  payments  in respect  thereof  are due to be made.  Such
right of offset shall not,  however,  apply after the  expiration of the initial
two (2) year term of the Lease.

         8.2 Buyer's Indemnity.

                  (a) Buyer shall  indemnify  and hold Seller  harmless from and
against, and shall defend promptly Seller from and reimburse Seller for, any and
all Damages which Seller may at any time suffer or incur,  or become subject to,
as a result of or in connection with:

                           (i) any  breach or  inaccuracy of any representations
         and warranties made by Buyer in or pursuant to this Agreement;

                           (ii) any  failure  by Buyer  to carry  out,  perform,
         satisfy and discharge any of its covenants,  agreements,  undertakings,
         liabilities,  or  obligations  under this Agreement or under any of the
         documents and materials delivered by Buyer pursuant to this Agreement;

                           (iii)  any  product   liability  matters  or  product
         warranty claims for products manufactured, distributed, sold or shipped
         by Buyer after the Closing;

                            (iv) the ownership, and/or operation of the Business
         and the Purchased Assets after the Closing; and

                            (v) the Assumed Liabilities; and

                            (vi) any suit,  action, or other proceeding  brought
         by any  governmental  authority  or  person  arising  out of any of the
         matters referred to in Section 8.2 of this Agreement.

                           (vii) the  Buyer's failure to fulfill its obligations
         under Sections 2.8(a) and 8.14.

                  (b) Seller shall promptly  notify Buyer of any claim,  demand,
action,  or  proceeding  for which  indemnification  will be sought  under  this
Section 8.2 of this Agreement and, if such claim, demand,  action, or proceeding
is a third party claim, demand, action, or proceeding, Buyer will have the right
at its expense to assume the defense thereof using counsel reasonably acceptable
to Seller. Seller shall have the right to participate,  at its own expense, with
respect to any such  third  party  claim,  demand,  action,  or  proceeding.  In
connection with any such third party claim, demand, action, or proceeding, Buyer
and Seller shall cooperate with each other and provide each other with access to
relevant  books and  records in their  possession.  No such third  party  claim,
demand, action, or proceeding shall be settled without the prior written consent
of Seller and Buyer.  If a firm  written  offer is made to settle any such third
party claim, demand,  action, or proceeding and Seller refuse to consent to such
settlement, then: (i)
                                       37
<PAGE>
Buyer shall be excused  from,  and Seller shall be solely  responsible  for, all
further defense of such third party claim,  demand,  action, or proceeding;  and
(ii) the maximum liability of Buyer relating to such third party claim,  demand,
action,  or  proceeding  shall be the amount of the proposed  settlement  if the
amount  thereafter  recovered  from  Seller on such third party  claim,  demand,
action,  or  proceeding  is greater than the amount of the proposed  settlement.
Notwithstanding the foregoing, Seller shall not be required to indemnify or save
harmless Seller in respect of any breach or inaccuracy of any  representation or
warranty  unless Seller shall have provided  notice to Seller in accordance with
this  Section  8.2(b) at or prior to the  expiration  of the period set forth in
Section 8.6.

         8.3 Termination.  Time is of the essence. Unless otherwise agreed to in
writing,  this Agreement may be terminated and the transactions  contemplated by
this  Agreement may be abandoned at any time as follows:  (a) by mutual  written
agreement of Seller and Buyer;  (b) by Buyer  (provided that it is not otherwise
in breach  hereof)  if any of the  conditions  set forth in  Article  VI of this
Agreement  shall not have been fulfilled on or prior to the Closing Date; (c) by
Seller  (provided  that it is not  otherwise  in  breach  hereof)  if any of the
conditions  set  forth in  Article  VII of this  Agreement  shall  not have been
fulfilled on or prior to the Closing Date.

         8.4 Rights on  Termination;  Waiver.  If this  Agreement is  terminated
pursuant to Section 8.3 hereof, all further  obligations of the parties under or

party to the other,  except for  violation  of Section  5.9  (cooperation),  and
except that Buyer's obligations contained in Section 5.1(b) (confidentiality) of
this Agreement shall survive any such termination.  If any of the conditions set
forth  in  Article  VI of this  Agreement  have not been  satisfied,  Buyer  may
nevertheless  elect  to  proceed  with  the  consummation  of  the  transactions
contemplated  by this  Agreement  and,  if any of the  conditions  set  forth in
Article VII of this Agreement have not been satisfied,  Seller may  nevertheless
elect to proceed with the consummation of the transactions  contemplated by this
Agreement.

         8.5 Further Assurances.  From time to time after the Closing Date, upon
the request of Buyer, and without further cost or expense to Buyer, Seller shall
execute  and  deliver,  and cause to be executed  and  delivered,  such  further
instruments of conveyance, assignment, and transfer and take such further action
as Buyer may  reasonably  request in order  more  effectively  to sell,  assign,
convey, transfer, reduce to possession, and record title to any of the Purchased
Assets.  Seller  agree to  cooperate  with Buyer in all  reasonable  respects to
assure to Buyer the continued title to and possession of the Purchased Assets in
the condition and manner contemplated by this Agreement.

         8.6 Survival of Representations and Warranties. All representations and
warranties of Buyer and Seller  contained in this  Agreement or made pursuant to
this  Agreement  shall  survive the  Closing  Date and the  consummation  of the
transactions  contemplated  by this  Agreement  for a  period  of two (2)  years
following  the  Closing  Date,  at  which  time  all  such  representations  and
warranties shall expire and terminate.

hereunder,  the parties  agree to use the  following  procedure  prior to either
party pursuing other available remedies:

                  (a) A meeting  shall be held  promptly  between  the  parties,
attended by individuals with decision-making authority regarding the dispute, to
attempt in good faith to negotiate a resolution of the dispute.

                  (b) If,  within  thirty  (30) days  after  such  meeting,  the
parties have not succeeded in negotiating a resolution of the dispute, they will
jointly appoint a mutually  acceptable neutral person not affiliated with either
of the  parties  (the  "neutral"),  seeking  assistance  in such regard from the
Center  for  Public  Resources  if they  have  been  unable  to agree  upon such
appointment  within 40 days from the  initial  meeting.  The fees of the neutral
shall be shared equally by the parties.

                  (c) In consultation with the neutral,  the parties will select
or devise an alternative dispute resolution procedure ("ADR") by which they will
attempt to  resolve  the  dispute,  and a time and place for the ADR to be held,
with the neutral making the decision as to the procedure,  and/or place and time
(but  unless  circumstances  require  otherwise,  not later than sixty (60) days
after  selection of the neutral) if the parties have been unable to agree on any
of such matters  within  twenty (20) days after  initial  consultation  with the
neutral.

                  (d) The parties agree to  participate in good faith in the ADR
to  its  conclusion  as  designated  by the  neutral.  If the  parties  are  not
successful in resolving the dispute  through the ADR, then the parties may agree
to submit the matter to binding arbitration or a private adjudicated  resolution
through the appropriate court.

                  (e) In the event  legal  proceedings  through  the  courts are
commenced to enforce the parties'  respective rights and obligations herein, the
prevailing  party shall be entitled to  reimbursement  for its related costs and
expenses,  including  reasonable legal fees, incurred with respect to said legal
proceedings.
