                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.    Financial Statement Presentation
      --------------------------------

      The  consolidated  financial  statements  have been prepared in accordance
      with generally accepted accounting  principles and include the accounts of
      the OrthoLogic Corp. and its subsidiaries (the "Company"). All significant
      intercompany accounts and transactions have been eliminated.

      The consolidated  balance sheet as of March 31, 1998, and the consolidated
      statements of  operations  and cash flows for the three months ended March
      31, 1998 and 1997 are  unaudited,  however,  in the opinion of management,
      include all adjustments  (consisting only of normal recurring adjustments)
      necessary for the fair presentation of the financial position,  results of
      operations  and cash  flows.  The  results of  operations  for the interim
      periods are not  necessarily  indicative of the results to be expected for
      the  complete  fiscal year.  The Balance  Sheet as of December 31, 1997 is
      derived from the Company's  audited financial  statements  included in the
      1997 annual  report.  It is suggested that these  financial  statements be
      read in  conjunction  with the  financial  statements  and  notes  thereto
      included in the Company's 1997 Annual Report.

2.    Acquisition
      -----------

      On March 3, 1997 and March 12, 1997, the Company  acquired  certain assets
      and assumed certain  liabilities of Toronto Medical Corp.  ("Toronto") and
      Danninger Medical Technology,  Inc. ("DMTI").  After paying certain of the
      assumed  liabilities,  the net cash outlay was approximately  $7.5 million
      for Toronto and $10.7 million for DMTI. Both  acquisitions  were accounted
      for as a purchase  which  resulted in goodwill of $4.5 million for Toronto
      and $9.5 million for DMTI. The goodwill is being amortized over 20 years.

      Had the  Toronto  and DMTI  acquisitions  occurred  on  January  1,  1997,
      combined  unaudited pro forma results for the three months ended March 31,
      1997 would have been $19.2 million net revenues,  ($764,000)  net earnings
      (loss),  and (0.3) net earnings  (loss) per common share.  The  operations
      were fully integrated in the Company's financial  statements for the first
      quarter of 1998.

3.    Co-promotion Agreement
      ----------------------

      The  Company  entered  into  an  exclusive,  co-promotion  agreement  (the
      "Agreement") with Sanofi Pharmaceuticals, Inc. ("Sanofi") on June 23, 1997
      for the purpose of marketing  Hyalgan,  a hyaluronic  acid sodium salt, to
      orthopaedic  surgeons in the United  States for the  treatment  of pain in
      patients  with  osteoarthritis  of  the  knee.  The  initial  term  of the
      agreement  ends on December 31, 2002.  Upon the  expiration of the initial
      term,  Sanofi may  terminate  the  agreement,  extend the agreement for an
      additional  one-year  period,  or enter into a revised  agreement with the
      Company. Upon termination of the Agreement, Sanofi
                                                                          Page 4
<PAGE>
      must pay the Company an equal to 50% of the gross compensation paid to the
      Company, pursuant to the Agreement, for the immediately preceding year.

      The Company is paid a  commission  which is based upon the number of units
      sold at the  wholesale  acquisition  costs less  amounts for  distribution
      costs,  discounts,  rebates  and  returns.  In  addition,  the  Company is
      obligated:  to use its best efforts to market and promote Hyalgan;  to pay
      Sanofi a royalty of 10% of the net selling price,  as defined;  and to pay
      the  manufacturer  of  Hyalgan a  product  transfer  price and a  pro-rata
      portion of a 10% royalty on combined annual net sales of Hyalgan by Sanofi
      and the  Company in excess of $30  million.  In  addition,  the Company is
      obligated to pay a total of $4.0 million during the first eighteen  months
      of the agreements.  During 1997 and the first quarter of 1998, the Company
      paid $2.0 million of this amount.  The Company has recorded the  remaining
      $2.0 million as a liability in its financial statements.

      The Company's sales force began to promote Hyalgan in the third quarter of
      1997.

4.    Licensing Agreement
      -------------------

      The  Company  announced  in January  1998 that it has  acquired a minority
      equity  interest in a biotech  firm,  Chrysalis  BioTechnology,  Inc.  for
      $750,000.  As part of the  transaction,  the  Company  has been  awarded a
      nine-month   world-wide   exclusive  option  to  license  the  orthopaedic
      applications of Chrysalin, a patented 23-amino acid peptide that has shown
      promise in  accelerating  the  healing  process.  Chrysalis  is  currently
      developing the technology to stimulate the skin-wound  healing process and
      has completed an extensive  pre-clinical  safety and efficiency profile of
      the product. In pre-clinical  animal studies,  Chrysalin was also shown to
      double the rate of fracture healing with a single injection into the fresh
      fracture gap. The Company's  agreement with Chrysalis contains  provisions
      for the  Company to  continue  and expand its option to license  Chrysalin
      contingent upon regulatory approvals,  successful pre-clinical trials, and
      certain trials and certain milestone payments to Chrysalis by the Company.
      The cost of performing the pre-clinical and clinical trials will be funded
      by the Company.  The Company will pursue  commercialization  of Chrysalin,
      initially  seeking  Food and Drug  Administration  approval  for the human
      clinical trials for the fracture-healing  indication. The Company projects
      that  Chrysalin  could  receive all the  necessary  FDA  approvals  and be
      introduced in the market during 2000. There can be no assurance,  however,
      that  the  clinical  trials  will  result  in  favorable  data or that FDA
      approvals, if sought, will be obtained.

5.    Litigation
      ----------

      During 1996  certain  lawsuits  were filed in the United  States  District
      Court for the District of Arizona against the Company and certain officers
      and  directors  alleging  violations  of Section  10(b) of the  Securities
      Exchange Act of 1934 and SEC Rule 10b-5 promulgated thereunder.

      Plaintiffs in these  actions  allege that  correspondence  received by the
      Company from the U.S. Food and Drug  Administration (the "FDA") pertaining
      principally to the promotion of
                                                                          Page 5
<PAGE>
      the  Company's   OrthoLogic  Bone  Growth   Stimulator  was  material  and
      undisclosed,  leading to an artificially inflated stock price.  Plaintiffs
      further alleged practices referenced in that correspondence  operated as a
      fraud  against  plaintiffs.  Plaintiffs  further  allege that once the FDA
      letter became known, a material  decline in the stock price of the Company
      occurred, causing damage to the plaintiffs.

      All plaintiffs seek class action status, unspecified compensatory damages,
      fees and  costs.  Plaintiffs  also seek  extraordinary,  equitable  and/or
      injunctive  relief as permitted by law. The actions were  consolidated for
      all  purposes  in the United  States  District  Court for the  District of
      Arizona and lead  plaintiffs and counsel were  appointed.  The Company and
      its officers and  directors  moved to dismiss the  consolidated  amendment
      complaint  for  failure  to  state  a  claim.   The  Court  dismissed  the
      consolidated amended complaint in its entirety against the Company and its
      officers and  directors but gave  plaintiffs  leave to amend all claims to
      cure all  deficiencies.  An amended complaint was filed in April, 1998 and
      the Company  plans to move again to dismiss the complaint on virtually the
      same grounds as it did before.

      In  addition,  the Company has been  served with a  substantially  similar
      action filed in Arizona  state court  alleging  state law causes of action
      grounded in the same set of facts.  This  action  remains  stayed  pending
      further developments in the Federal consolidated class action.

      In addition to the foregoing,  a shareholder derivative complaint alleging
      among  other  things,  breach of  fiduciary  duty in  connection  with the
      conduct  alleged in the  aforesaid  federal and state court class  actions
      have also been filed in Arizona state court.  That action  remains  stayed
      pending further developments in the Federal consolidated class action.

      In March  1998,  the former  owner of the CPM assets  acquired in the DMTI
      acquisition  filed a  lawsuit  in the Court of  Common  Pleas in  Franklin
      County,  Ohio against the Company.  The plaintiff alleges that the Company
      breached the acquisition  agreement by not satisfying certain  liabilities
      it assumed in the acquisition  and that the Company  breached an ancillary
      agreement   for  the  temporary   provision  of  services   following  the
      acquisition.  Plaintiff has also demanded from the Court of Common Pleas a
      declaration  that the  Company is not  entitled  to cash  escrowed  in the
      acquisition.  The Company had previously  requested  delivery to it of the
      escrowed cash and demanded indemnification for the plaintiff's breaches of
      representations  and warranties in the  acquisition  agreement.  The costs
      associated  with defending  these  allegations  and the potential  outcome
      cannot be  determined at this time and  accordingly,  no estimate for such
      costs have been included in these financial statements.

      Management  believes  that the  allegations  are  without  merit  and will
      vigorously defend them.

      At March 31,  1998,  the  Company  is  involved  in  various  other  legal
      proceedings that arose in the ordinary course of business. In management's
      opinion, the ultimate resolution of
                                                                          Page 6
<PAGE>
      these  other  legal  proceedings  will not have a  material  affect on the
      financial position, results of operations, or cash flow of the Company.

6.    New Accounting Pronouncements
      -----------------------------

      Effective  January 1, 1998,  the Company  adopted  Statement  of Financial
      Accounting  Standard  No. 130  "Reporting  Comprehensive  Income." For the
      quarter  ended  March 31,  1998,  net  income  approximated  comprehensive
      income.

7.    Debt
      ----

      Subsequent  to quarter end, the Company  signed an addendum to an accounts
      receivable  revolving line of credit agreement reducing the line of credit
      balance from $10 million to $7.5 million.

8.    Allowance For Doubtful Accounts
      -------------------------------

      The allowance for doubtful  accounts was increased by  approximately  $9.3
      million  during  the first  quarter  of 1998  over and  above  the  normal
      quarterly activity.  The increase was a result of a management decision to
      focus resources on collection of current sales and on  re-engineering  the
      overall process of billing and collections.  It is no longer considered to
      be as cost effective to expend significant  resources on the collection of
      the older receivables as had been done in the past.
                                                                          Page 7

OrthoLogic's  revenues increased 10% to $19.1 million from $17.3 million for the
same  period a year ago.  The  increase is  primarily  the result of revenue for
Hyalgan  which was launched in July 1997.  Revenue from the  Continuous  Passive
Motion  rentals  was  greater  than  expected  during  the  quarter,  offsetting
declining sales of fracture fixation devices.

Gross Profit

Gross profit  increased from $12.6 million in the first quarter of 1997 to $14.7
million in the first  quarter of 1998.  Gross profit as a percentage  of revenue
was 77% for the three  months  ended  March  31,  1998  compared  to 73% for the
comparable period during 1997.

Selling, General and Administrative Expenses

Selling,  general and  administrative  (SG&A)  expenses for the first quarter of
1998 were $23.8 million,  up $10.9 million from the  comparable  period in 1997.
The increase from 1997 is due in part to the variable costs  associated with the
increased revenue.  The first quarter of 1998 also included the costs associated
with the acquisition previously discussed.

The SG&A  expenses  include an increase  of $9.3  million in the  allowance  for
uncollectable accounts over the normal quarterly provision.  As part of a larger
project to re-engineer the sales,  billings and collection  process for enhanced
efficiencies,  the Company obtained independent  evaluation of its billing files
and collection  strategies in April of 1998. The information  obtained from this
study prompted  management to change its focus for future collection  efforts to
be  primarily on the more recent  sales.  The cost of  continuing  to manage the
older accounts  receivable balances to the extent that had been done in the past
is no longer  considered as cost  effective  for the Company.  This shift in the
emphasis  for the  collections  policy  prompted the Company to increase the bad
debt reserve for the outstanding  balances of the older  receivables.  Excluding
bad debt,  total  SG&A  expenses  decreased  to 66% of total  sales in the first
quarter of 1998, from 68% in 1997.
                                                                          Page 8

Research and Development

Research and  development  (R&D) expenses were $498,000 for the first quarter of
1998 compared to $576,000 for the comparable  1997 period.  The decrease was due
to the unveiling of a new, single coil version of the OL-1000, no longer in R&D.
The device extends the fracture healing benefits of the OL-1000 to the thigh and
the long bone of the upper arm, extending from the shoulder to the elbow, and is
suitable  for  the  treating  non-union  fractures  in  most  areas  for  larger
individuals.

Other Income and Expenses

There was a reversal of expenses  charged to restructuring in a prior period for
$399,000.  Other  income  declined to $97,000 in the first  quarter of 1998 from
$636,000  during the same period in 1997. This decrease is attributed to (1) the
Company has not  participated in any research grant projects in the current year
and (2) the  reduction  in the  amount  in cash and  investments  has  yielded a
reduction in the interest  income  earned in the quarter to $97,000 in 1998 from
$562,000 in 1997.

Liquidity and Capital Resources

On March 31, 1998, the Company had cash and investments of $4.9 million compared
to $12.3 million at December 31, 1997.  The decrease in cash and  investments is
primarily the result of a $1 million payment under a co-promotion  agreement,  a
$1.2 million increase in inventory, and a $1.6 million increase in fixed assets,
mostly for the Ortho Rehab  rental  fleet  business.  In  addition,  in January,
OrthoLogic  acquired a $750,000  equity  interest in a biotech  firm,  Chrysalis
BioTechnology, Inc., located in Galveston, Texas.

Subsequent  to quarter  end,  the  Company  signed an  addendum  to an  accounts
receivable  revolving  line of  credit  agreement  reducing  the line of  credit
balance from $10 million to $7.5 million and removing the  equipment  advance of
$2.5  million.  The  Company  anticipates  that its  cash on hand and the  funds
available  from this line of credit  will be  sufficient  to meet the  Company's
projected cash and working capital  requirements  for the next 12 months.  There
can be no  assurance,  however,  that  this will  prove to be the  case.  If the
Company were required to obtain additional financing in the future, there can be
assurance  that such sources of capital will be available on terms  favorable to
the Company, if at all.

<PAGE>
                         IV. OPTION GRANTS AND PAYMENTS

         Chrysalis  hereby  grants to  OrthoLogic a series of options to acquire
exclusive United States and worldwide  licenses,  as set forth below, to make or
have made,  use, sell and  sublicense  Licensed  Products  under the  Technology
Rights for Orthopaedic  Applications  of the type  described.  Each such license
shall run for the lives of all Patents and other patents owned by or licensed to
Chrysalis,  and related to any Licensed  Product,  which are appropriate for the
territory licensed. In exchange, OrthoLogic shall make the payments described in
this  Article IV. Such  payments  shall not be credited  against  royalties  due
pursuant to Article V. Promptly after  OrthoLogic  gives Chrysalis notice of its
determination to proceed and exercise its option to secure any license described
below,  the  parties  shall  complete  and  execute a Patent  License  Agreement
containing all provisions  contemplated by this Agreement and which otherwise is
in a form that is  commercially  reasonable for similar  licenses.  All payments
described herein shall be payable via wire transfer into an account specified by
Chrysalis.

         a. At or  before  September  30,  1998,  if  OrthoLogic  determines  to
proceed,  it shall pay an  additional  $750,000 to secure the  exclusive  United
States license for fracture applications.

         b. On or before December 31, 1998, if OrthoLogic determines to proceed,
it shall pay an  additional  $250,000  to  continue  its  option  to expand  its
exclusive  United  States  license for fracture  applications  into an exclusive
worldwide  license and to continue  its option to license all other  Orthopaedic
Applications.

         c. On or before June 30, 1999, if OrthoLogic  determines to proceed, it
shall pay an additional  $500,000 to secure the exclusive  United States license
for all Orthopaedic Applications (except for fracture applications,  which would
already have been licensed).

         d. On or before June 30, 1999, if OrthoLogic  determines to proceed, it
shall pay an additional $1,000,000 to secure the exclusive worldwide license for
all Orthopaedic Applications, including fracture applications. The parties agree
to negotiate in good faith with respect to reasonable  additional  payments that
will be based on commercialization of TP508 outside the United States.

         e. OrthoLogic  shall pursue the following  milestones on a best efforts
basis  and  make  the  following  additional  payments  to  Chrysalis  upon  the
occurrence  of the events or at the required  time noted in item (v), so long as
OrthoLogic,  one  of  its  Affiliates,  or  a  sublicensing  partner,  is  still
proceeding with the license or licenses contemplated by each such payment:

                  (i)      $500,000  upon  FDA  approval  of  the  IDE or IND to
                           initiate a fracture healing clinical trial.

                           trial for each new orthopaedic indication.

                  (v)      If an  FDA-approved  clinical  trial  for  the  first
                           additional  Orthopedic  application has not been made

         f.  If  OrthoLogic  fails  to  meet  the  milestones  or  does  not use
reasonable  efforts to  commercialize  Chrysalis  Products in the United States,
provided  that the  conditions  described in (h) below are met, (i) at any time,
Chrysalis  shall  have the  option to convert  the  United  States  license to a
non-exclusive  license, or (ii) at any time after June 30, 1999, Chrysalis shall
have the option to terminate the United States license completely.

         g. If OrthoLogic  exercises its right to secure the exclusive worldwide

Chrysalis  shall  give  OrthoLogic  75  days  written  notice  of  the  proposed
conversion or  termination,  provided that, in either case,  the  termination or
conversion  shall not  become  effective  if within  the 75 days  following  the
effective date of the notice,  OrthoLogic  provides written evidence that it has
commercialized  or is actively  attempting to  commercialize a Licensed  Product
within the US or internationally as appropriate. Evidence provided by OrthoLogic
that it has an ongoing and active research, development,  regulatory compliance,
manufacturing,  marketing or licensing  program as appropriate,  directed toward
production and sale of Licensed  Products  within the US or  internationally  as
appropriate shall be deemed satisfactory evidence of using best efforts.

         i. In the event that  either  the US or the  World-wide  license  for a
specific  application is forfeited by OrthoLogic,  Chrysalis will have access to
all data collected specifically related to that application.

                                  V. ROYALTIES

         5.1  Percentages.  After the parties  have  executed  the first  patent
license  contemplated by this Agreement,  OrthoLogic  shall pay to Chrysalis for
such license and all other the licenses to the  Technology  Rights  subsequently
granted hereunder,  royalties for sales of Licensed Products calculated pursuant
to the table which follows this  paragraph.  For purposes of these  calculations
                                       -4-
<PAGE>
all  sales  under all  licenses  granted  pursuant  to this  Agreement  shall be
cumulated and treated as a single amount.

                    Incremental Sales    Royalty Rate

                    First  $20 million        8.0%
                    Next   $30 million        6.0%
                    Next   $50 million        5.0%
                    Next  $100 million        4.0%
                    Over  $200 million        2.5%


         5.2  Minimums.  For each year after  Commercialization,  regardless  of
actual sales, OrthoLogic shall pay (for all licenses to all technology or patent
rights licensed from Chrysalis pursuant to this Agreement),  during the first 12
months  after  Commercialization  of at least  $250,000,  royalties  of at least
$500,000 during the second 12 months after  Commercialization,  and royalties of
at least $750,000  during the third 12 months after  Commercialization.  In that
regard,  OrthoLogic  shall  pay to  Chrysalis  a  sufficient  amount in its last
quarterly payment for each calendar year to reach the minimum annual royalty.



                            VI. PAYMENTS AND REPORTS

         6.1 Reports.  OrthoLogic  shall  provide to  Chrysalis,  on a quarterly
basis, a written report of all sales of Licensed Products for which a royalty is
due or payable under this Agreement.  Such report shall be due within 45 days at
the end of each calendar quarter, whether or not royalties are due, and shall be
accompanied by a remittance from OrthoLogic to Chrysalis of all earned royalties
specified by Sections 5.1 and 5.2.

         6.2 Records.  OrthoLogic  shall keep  suitable  books of records of all
manufacture,  use,  or sale of  Licensed  Products  for which a  royalty  is due
hereunder for at least three years, unless in dispute, in which event they shall
be kept until such dispute is settled, and shall make such records available for
inspection by  Chrysalis,  or its designee,  upon  reasonable  notice and during
normal hours of operation of OrthoLogic.

         6.3 Third Party Contest.  If a third party contests the validity of any
of the  Patent  Rights  granted  hereunder,  OrthoLogic  shall  continue  to pay
royalties with respect to that patent as if such contest were not underway until
the patent is adjudicated invalid or unenforceable by a court of last resort.

                         VII. TRANSFERS AND SUBLICENSES

         OrthoLogic  may  transfer any Licensed  Products to any  Affiliates  or
sublicensees  without  any  such  transfers  being  considered  as  sales of the
Licensed  Products.  OrthoLogic  may also  sublicense  any of the license rights
granted  hereunder  provided  that:  (1) each  Affiliate or sublicensee to which
OrthoLogic  sublicenses  agrees in writing to honor the terms of this
                                      -5-
<PAGE>
Agreement  and (2)  OrthoLogic  agrees to pay to  Chrysalis  milestone  payments
described in Article IV and the earned royalty due under Section 4.2 for all Net
Sales of Licensed  Products by any Affiliate or sublicensee  just as if such Net
Sales were made directly by OrthoLogic.


                      VIII. PURCHASES OF CHRYSALIS PRODUCTS

         8.1  Chrysalis  to  Manufacture.  Except as  provided  in  Article  IX,
Chrysalis  will  retain all  exclusive  rights to  manufacture  TP508 or related
peptides  to be used in  Licensed  Products,  and in  product  development,  for
Orthopaedic  Applications,  and  OrthoLogic  agrees to  purchase  such  peptides
exclusively from Chrysalis for all preclinical  studies,  clinical  trials,  and
final end-product sales.

         8.2 Materials Transfer Agreement.  Promptly after the execution of this
Agreement,  the parties will prepare and execute a materials transfer agreement,
with commercially  reasonable terms, whereby, until the expiration of all patent
license  agreements  contemplated  by this  Agreement,  Chrysalis  will agree to
provide TP508 or related  peptides for  preclinical  studies (GLP or equivalent,
lot verified) in 1 milligram  vials (not sterile) for $150 per milligram or in 5
milligram vials (not  sterilized) for $80 per milligram ($400 per vial).  During
the  term of any  patent  license  agreement  contemplated  by  this  Agreement,
Chrysalis will also supply TP508 or related peptides for end-product manufacture
and  commercial  use, as follows:  Small  quantity vials (up to 3 micrograms per
vial),  sterile,  delivered,  $15.00  each;  and 5-10  gram  bulk,  non-sterile,
delivered $3.00 per microgram.

         8.3 Payment. The purchase price for each Chrysalis Product purchased by
OrthoLogic  shall  be due and  payable  30 days  after  the date of  receipt  by
OrthoLogic

         8.4 Forecasts.  During the first 90 days of 1998, with respect to 1998,
and no later  than 30 days  prior to the start of the year with  respect to 1999
and later years, OrthoLogic and Chrysalis will agree to a reasonable forecast of
the number of Chrysalis Products, by type, that will be purchased from Chrysalis
by  OrthoLogic  during the  appropriate  calendar  year and during each  quarter
thereof.  OrthoLogic will be required to purchase at least 100% of the quarterly
amounts as forecasted.  However,  OrthoLogic may revise each quarterly  forecast
plus or minus 50% of the original  forecasted  amount,  provided that changes to
the  forecast  for a  quarter  must be made no later  than the  first day of the
preceding quarter.

         8.5  Shipment  and  Risk.   Chrysalis  will  ship  to  OrthoLogic,   at
Chrysalis's  expense,  the  Chrysalis  Products  that are  actually  ordered  as
specified in the  appropriate  binding  purchase  order.  Title and risk of loss
shall pass to OrthoLogic when the Chrysalis Product is delivered to OrthoLogic.

         8.6 Chrysalis'  Obligation.  To the extent that the amount of Chrysalis
Products  ordered by OrthoLogic with respect to any quarter does not exceed 125%
of the higher of (i) the  forecast  made  pursuant  to Section  8.4, or (ii) the
average amount ordered  during the prior three months,  Chrysalis  agrees to use
its best  efforts to  manufacture  and ship the  Chrysalis  Products  ordered by
OrthoLogic within 30 days after receipt of the appropriate purchase order.

                      IX. ORTHOLOGIC'S RIGHT TO MANUFACTURE

         9.1 OrthoLogic  Right.  OrthoLogic  shall have the right to manufacture
Chrysalis Products for exclusive use in areas granted to OrthoLogic by Chrysalis
if Chrysalis fails to deliver Chrysalis Products as specified in Section 9.2, or
upon the  occurrence of any of the events  described in Section 9.3. In any such
event, the contents of the escrow described in Section 9.4 shall be delivered to
OrthoLogic promptly.  If the contents of the escrow are delivered to OrthoLogic,
OrthoLogic  shall take reasonable  steps to protect the  confidentiality  of the
escrowed materials.

         9.2  Grace  Period.  Chrysalis  shall  have a  minimum  of four  months
following any applicable date for the delivery of Chrysalis Products in which to
deliver at least 90% of the Chrysalis Products due on such date, as contemplated
by Section 8.6.

         9.3 Other Events.  OrthoLogic  shall also have the right to manufacture
Chrysalis Products upon the occurrence of any of the following events:

         a. Chrysalis has ceased its on-going business operations,  or the sale,
licensing,  proper  maintenance  or other  reasonable  support of the Technology
Rights; or either cannot manufacture or elects to discontinue the manufacture of
Chrysalis Products.

         b.  Chrysalis has availed itself of, or been subjected by a third party
to, a proceeding in bankruptcy in which Chrysalis is the named debtor;  there is
an assignment by Chrysalis for the benefit of its creditors the appointment of a
receiver for  Chrysalis or any other  proceeding  involving  the  insolvency  of
Chrysalis or the protection of or from its creditors,  and the same has not been
discharged  or  terminated  without  any  prejudice  to  OrthoLogic's  rights or
interests  under  this  License  Agreement  within  60 days  (unless  reasonable
alternative provisions have been made to protect the rights of OrthoLogic).

         c. Any other  event or  circumstance  occurs  which  demonstrates  with
reasonable  certainty the inability or unwillingness of Chrysalis to fulfill its
obligations to OrthoLogic, including, without limitation, the maintenance of and
the correction of defects in the Chrysalis Products.

         9.4  Escrow.  Chrysalis  agrees  that it  will  enter  into  an  escrow
agreement  with a third party  acceptable to Chrysalis and  OrthoLogic  and will
deposit with the escrow agent all  formulae and  specifications  relating to the
Chrysalis  Products and their  production,  including  all relevant  commentary,
explanations and other documentation, as well as instructions sufficient for the
production of such products,  and will name OrthoLogic as the beneficiary of the
escrow  agreement.  The cost of the escrow agent's  services  pertaining to this
Agreement will be split equally between OrthoLogic and Chrysalis.

         9.5 Expiration of OrthoLogic Limited Manufacturing Right. Chrysalis can
regain  the  right  to  manufacture  products  for  OrthoLogic  (thereby  ending
OrthoLogic's  Limited  Right  to  Manufacture)  if it can  provide  satisfactory
written evidence that it can meet  OrthoLogic's  supply
                                      -7-
<PAGE>
needs  for a period  of at least one year.  Sufficient  evidence  shall  include
having a  sufficient  inventory of Chrysalis  Products  for  OrthoLogic  to meet
OrthoLogic's needs, or other written documentation that demonstrates  Chrysalis'
ability to provide  products to  OrthoLogic  in a timely  matter as described in
this Agreement.  OrthoLogic will still retain the right to regain  manufacturing
rights whenever Chrysalis fails to perform as described in Section 9.1.

                               X. PRODUCT CHANGES

         10.1  Improvements.  From time to time,  OrthoLogic  or  Chrysalis  may
identify possible improvements or change opportunities with respect to Chrysalis
Products for Orthopedic  Applications.  Chrysalis and  OrthoLogic  agree to work
together to determine  whether  appropriate  and  cost-effective  changes can be
engineered and cleared through applicable regulatory agencies.

         10.2 Pricing. After the occurrence of a situation of the type described
in paragraph 10.1, Chrysalis will work with OrthoLogic to design an orderly plan
for the introduction and pricing of such modifications,  with particular concern
for the prior pricing structure, the benefits to the treatment of patients using
or  potentially  using the Chrysalis  Products and the efficient and  profitable
operation of the businesses of Chrysalis and OrthoLogic.

Agreement  shall be binding  upon any party unless made in writing and signed by
all parties.

         16.11 Force  Majeure.  Neither  party shall be in default  hereunder by
reason of its delay in the  performance  of or  failure  to  perform  any of its
obligations  hereunder,  if such delay or failure is caused by strikes,  acts of
God  or  a  public  enemy,  riots,  fire,  interference  by  civil  or  military
authorities,  compliance with governmental  laws, rules,  regulations or orders,
delays in  transit  or  delivery,  inability  to secure  necessary  governmental

state or city or other  international  or domestic  governmental  body, (ii) the
indemnifying  party's  actions or omissions in  furtherance  of this  Agreement,
(iii) any breach of a representation  or warranty by or any breach or default in
the  performance of any obligation of the  indemnifying  party, or (v) any other

Agreement  or at any other  address  such  person or entity  has  designated  by
notice.

         16.14 Severability. If any term or other provision of this Agreement is
invalid,  illegal or incapable  of being  enforced by any rule or law, or public
policy, all other conditions and provisions of this Agreement shall nevertheless
remain in full force and effect so long as the  economic or legal  substance  of
the transactions  contemplated  hereby are not affected in any manner materially
adverse  to  either  party.  Upon  such  determination  that  any  term or other
provisions is invalid, illegal or incapable of being enforced, the parties shall
negotiate  in good faith to modify this  Agreement  so as to effect the original
intent of the parties as closely as possible in a 
                                      -14-

mutually  acceptable  manner in order that the  transactions  be  consummated as
originally contemplated to the fullest extent possible.

Agreement  that by their nature  survive and continue  after any  expiration  or
termination  of  this  Agreement,   shall  bind  the  parties  and  their  legal

         16.16  Waiver.  The  failure  of  either  party  to  insist  on  strict
performance of any term or condition  hereof or to exercise any option contained
herein, shall not be construed as a waiver of that party's right to enforce that
term of condition in the future or any other term or condition to this Agreement
in any other instance.

         16.17 Independent Entities. Chrysalis and OrthoLogic each have separate
and independent  rights and obligations under this Agreement.  Nothing contained

         A.       Modification(s) to Loan Agreement
                  ---------------------------------

                  1.       Section 2.3 (a)  entitled  "Interest  Rate" is hereby
                           amended in its entirety to read as follows:

                                    (a)  Interest  Rate.  (i)  Advances   accrue
                           interest on the  outstanding  principal  balance at a
                           per annum rate of .650 of a  percentage  point  above
                           the Prime Rate;  and (ii) Equipment  Advances  accrue
                           interest on the  outstanding  principal  balance at a
                           per annum rate of .450 of a  percentage  point  above
                           the Prime Rate. Upon Borrower achieving 2 consecutive
                           quarters of  profitability,  the interest rate on the
                           Committed  Revolving Line and the Committed Equipment
                           Line will reduce by .10% and will  further  reduce by
                           .10% upon Borrower  achieving 4 consecutive  quarters
                           of  profitability.  In addition,  upon improvement of
                           Borrower's  balance  sheet  sufficient  to  meet  the
                           Original Covenants (as amended herein),  the interest
                           rate for the Advances  under the Committed  Revolving
                           Line will  decrease to the original  interest rate of
                           .200 of a percentage point above the Prime Rate. Such
                           interest  rate change  shall be  effective  as of the
                           first day of the month  following  Bank's  receipt of
                           Borrower's financial  statements  indicating Borrower
                           has met the above-described  criteria. After an Event
                           of  Default,  Obligations  accrue  interest  at  5.00
                           percentage    points   above   the   rate   effective
                           immediately before the Event of Default. The interest
                           rate  increases  or  decreases  when the  Prime  Rate
                           changes.  Interest  is computed on a 360 day year for
                           the actual number of days elapsed.

                           Borrower  will  deliver  to  Bank  with  the  monthly
                           financial statements;  cash flow reports covering the
                           three  previous  months and the three future  months;
                           and a Compliance  Certificate signed by a Responsible
                           Officer in the form of Exhibit D.

                           (d) Bank has the right to audit  Borrower's  Accounts
                           at  Borrower's  expense,   but  the  audits  will  be
                           conducted on a  semi-annual  basis unless an Event of
                           Default has occurred and is continuing.

                  3.       Section 6.7 entitled "Financial  Covenants" is hereby
                           amended in its entirety to read as follows:

                           (iv)   Profitability.   Borrower   will  not   suffer

                           $5,000,000 in aggregate for the quarters ending March
                           31, 1998 and June 30, 1998  excluding  any  scheduled
