                                ORTHOLOGIC CORP.


                         Pursuant to Section 151 of the
                        Delaware General Corporation Law


         OrthoLogic  Corp., a corporation  organized and existing under the laws
of the  State  of  Delaware  (the  "Corporation"),  hereby  certifies  that  the
following  resolutions  were  duly  adopted  by the  Board of  Directors  of the
Corporation  pursuant  to the  authority  of the Board of  Directors  granted by
Section 151 of the Delaware General Corporation Law.

         RESOLVED,  that  pursuant  to the  authority  granted  to the  Board of
Directors in accordance with the provisions of the Corporation's  Certificate of
Incorporation,  as amended, the Board of Directors hereby authorizes a series of
the Corporation's  previously  authorized Preferred Stock, par value $0.0005 per
share (the "Preferred  Stock"),  to be issued pursuant to a Securities  Purchase
Agreement  between  the  Corporation  and  the  Purchasers  named  therein  (the
"Securities Purchase  Agreement"),  and hereby states the designation and number
of  shares,  and  fixes  the  relative  rights,   preferences,   privileges  and
restrictions thereof as follows:

1. DESIGNATION AND AMOUNT.

         The  designation  of this  series,  which  consists of twenty  thousand
(20,000)  shares (the  "Preferred  Shares") of Preferred  Stock, is the Series B
Convertible Preferred Stock (the "Series B Preferred Stock") and the face amount
shall be One Thousand Dollars ($1,000) per share (subject to ratable  adjustment
in the event of any stock split or combination  of the Series B Preferred  Stock
and to equitable  adjustment in the event of a reclassification  of the Series B
Preferred Stock or other similar event)(the "Stated Value"). The date on which a
Preferred Share is issued and sold pursuant to the Securities Purchase Agreement
is  referred  to herein as the  "Issue  Date" and,  in the event that  Preferred
Shares are issued in more than one tranche  pursuant to the Securities  Purchase
Agreement,  the Issue Date relating to the Preferred  Shares issued in the first
such tranche is referred to herein as the "Initial Issue Date".

2. DIVIDENDS. The Series B Preferred Stock will not bear dividends.

3. PRIORITY.

         (a) Payment upon Dissolution.

                  (i) Upon the  occurrence  of (x) any  insolvency or bankruptcy
proceedings, or any receivership,  liquidation,  reorganization or other similar
proceedings  in connection  therewith,  commenced by the  Corporation  or by its
creditors, as such, or relating to its assets or
<PAGE>
(y) the  dissolution  or other  winding up of the  Corporation  whether total or
partial,   whether  voluntary  or  involuntary  and  whether  or  not  involving
insolvency or bankruptcy  proceedings,  or (z) any assignment for the benefit of
creditors or any marshalling of the material  assets or material  liabilities of
the Corporation (each, a "Liquidation  Event"), no distribution shall be made to
the  holders of any  shares of Junior  Securities  (as  defined  below)  unless,
following  the  payment of  preferential  amounts on all Senior  Securities  (as
defined  below),   each  Holder  of  Preferred  Shares  (each,  a  "Holder"  and
collectively,  the "Holders") shall have received the Liquidation Preference (as
defined below) with respect to each Preferred Share then held by such Holder. In
the event that upon the  occurrence  of a Liquidation  Event,  and following the
payment of preferential amounts on all Senior Securities (as defined below), the
assets  available for  distribution to the Holders and the holders of Pari Passu
Securities are  insufficient to pay the  Liquidation  Preference with respect to
all of the outstanding  Preferred Shares and the preferential amounts payable to
such holders,  the entire assets of the Corporation shall be distributed ratably
among the Preferred Shares and the shares of Pari Passu Securities in proportion
to the ratio that the  preferential  amount  payable  on each such share  (which
shall be the Liquidation  Preference in the case of a Preferred  Share) bears to
the aggregate preferential amount payable on all such shares.

                  (ii) The "Liquidation  Preference" with respect to a Preferred
Share shall mean an amount  equal to the Stated Value of such  Preferred  Share.
"Junior  Securities"  shall mean the Common Stock and all other capital stock or
securities of the Corporation  that are not Pari Passu Securities or do not have
a  preference  over the Series B  Preferred  Stock in respect of  redemption  or
distribution upon liquidation. "Pari Passu Securities" shall mean any securities
ranking pari passu with the Series B Preferred Stock in respect of redemption or
distribution upon liquidation.  "Senior Securities" shall mean any securities of
the  Corporation  which by  their  terms  have a  preference  over the  Series B
Preferred Stock in respect of redemption or distribution upon liquidation.

4. CONVERSION.

         (a) Right to Convert.  Each  Holder  shall have the right to convert on
the three  hundredth  (300th) day following the Initial Issue Date (the "Initial
Conversion  Date") or at any time  thereafter,  all or any part of the Preferred
Shares held by such  Holder  into such  number of fully paid and  non-assessable
shares  ("Conversion  Shares") of the Company's  common stock, par value $0.0005
per share (the "Common  Stock"),  as is determined in accordance  with the terms
hereof (a "Conversion"); provided, however, that in the event that, prior to the
three  hundredth  (300th) day following  the Initial Issue Date,  either (i) the
Corporation enters into an agreement relating to a Change of Control Transaction
(as defined below)  immediately  upon which event the  Corporation  shall make a
public  announcement  of such  transaction,  (ii) a Material  Adverse  Event (as
defined below) occurs or (iii) a Mandatory  Redemption  Event (as defined below)
occurs  (each of (i),  (ii) and  (iii)  being  referred  to  herein as an "Early
Conversion  Event"),  the Initial  Conversion  Date for purposes hereof shall be
deemed to be the  first  date on which an Early  Conversion  Event  occurs.  For
purposes of this paragraph  4(a),  the term "Material  Adverse Event" shall have
the meaning set forth in the Securities Purchase Agreement.  In the event that a
Material Adverse Event occurs,  the Company must immediately  notify each Holder
of such occurrence and at the same time make a public announcement thereof.

         (b) Conversion  Notice.  In order to convert Preferred Shares, a Holder
shall send by facsimile  transmission,  at any time prior to 11:59 p.m., eastern
time,  on the date on which such Holder  wishes to effect such  Conversion  (the
"Conversion  Date"),  (i) a notice of conversion  (a  "Conversion  Notice"),  in
substantially the form of Exhibit A hereto, to the Corporation and to
                                      -2-
<PAGE>
the  Corporation's  transfer agent for the Common Stock (the  "Transfer  Agent")
stating  the  number  of  Preferred  Shares  to  be  converted,  the  applicable
Conversion Price (as defined below) and a calculation of the number of shares of
Common Stock issuable upon such Conversion and (ii) a copy of the certificate or
certificates representing the Preferred Shares being converted. The Holder shall
thereafter send the original of the Conversion Notice and of such certificate or
certificates  to  the  Transfer  Agent.  The  Corporation   shall  issue  a  new
certificate  for  Preferred  Shares  in the  event  that  less  than  all of the
Preferred  Shares  represented by a certificate  delivered to the Corporation in
connection with a Conversion are converted. Except as otherwise provided herein,
upon delivery of a Conversion  Notice by a Holder in  accordance  with the terms
hereof,  such Holder shall, as of the applicable  Conversion Date, be deemed for
all purposes to be the record owner of the Common Stock to which such Conversion
Notice relates. In the case of a dispute between the Corporation and a Holder as
to the  calculation of the Conversion  Price or the number of Conversion  Shares
issuable upon a Conversion,  the Corporation shall promptly issue to such Holder
the number of  Conversion  Shares  that are not  disputed  and shall  submit the
disputed calculations to its independent  accountant within one (1) Business Day
of receipt of such Holder's  Conversion Notice. The Corporation shall cause such
accountant to calculate the  Conversion  Price as provided  herein and to notify
the  Corporation and such Holder of the results in writing no later than two (2)
Business Days following the day on which it received the disputed  calculations.
Such accountant's  calculation shall be deemed conclusive absent manifest error.
The fees of any such accountant  shall be borne by the party whose  calculations
were most at variance with those of such accountant.

         (c)  Number of  Conversion  Shares;  Conversion  Price.  The  number of
Conversion  Shares to be delivered by the  Corporation  pursuant to a Conversion
shall be  determined  by dividing the  aggregate  Stated Value of the  Preferred
Shares to be converted by the Conversion  Price (as defined herein) in effect on
the applicable  Conversion Date.  Subject to adjustment as provided in Section 6
below,  "Conversion  Price" with respect to a Preferred Share shall mean (A) for
any Conversion occurring during the period of three hundred (300) days following
the Issue  Date  relating  to such  Preferred  Share  (the  "Initial  Conversion
Period"),  the  average of the ten (10)  lowest  Closing  Bid Prices (as defined
below) for the Common Stock  occurring  during the period of thirty (30) Trading
Days (as defined below)  immediately prior to (but not including) the applicable
Conversion  Date (the  "Floating  Conversion  Price") and (B) for any Conversion
occurring  after the  Initial  Conversion  Period,  the  lesser of the  Floating
Conversion Price and the Fixed Conversion  Price. The "Fixed  Conversion  Price"
with  respect to a Preferred  Share  shall mean one  hundred  and three  percent
(103%) of the average  Closing Bid Price for the Common  Stock during the period
of ten (10)  Trading Days  immediately  prior to (but not  including)  the three
hundredth (300th) day following the Issue Date relating to such Preferred Share;
provided, however, that if the Corporation is not eligible to register shares of
Common Stock on a registration  statement on Form S-3 on or before  September 1,
1998 (the  "Registration  Event"),  the Fixed Conversion Price with respect to a
Preferred  Share shall mean, (x) during the period  beginning on the one hundred
and  eightieth  (180th) day  following the Initial Issue Date and ending on such
three hundredth day, one hundred and three percent (103%) of the average Closing
Bid Price for the  Common  Stock  during  the  period of ten (10)  Trading  Days
immediately prior to (but not including) such one hundred and eightieth day, and
(y) from and  after  such  three  hundredth  day,  the  lesser  of (I) the Fixed
Conversion Price as determined pursuant to the immediately  preceding clause (x)
and (II) the Fixed  Conversion  Price that would  otherwise be in effect had the
Registration Event not occurred.

         (d)  Certain  Definitions.  "Trading  Day"  means  any day on which the
Common Stock is traded on the principal  securities  exchange or market on which
the Common Stock is then traded.  "Closing Bid Price" means, with respect to the
Common  Stock,  the closing bid price for the Common Stock  occurring on a given
Trading Day on the principal securities exchange or
                                      -3-
<PAGE>
trading  market where such security is listed or traded as reported by Bloomberg
Financial Markets or, if Bloomberg  Financial Markets is not then reporting such
prices, by a comparable reporting service of national reputation selected by the
Corporation  and  reasonably  acceptable  to holders  of a majority  of the then
outstanding  Preferred  Shares  (collectively,  "Bloomberg") or if the foregoing
does  not  apply,   the  last  reported  bid  price  of  such  security  in  the
over-the-counter  market on the  electronic  bulletin board for such security as
reported  by  Bloomberg,  or, if no bid price is reported  for such  security by
Bloomberg,  the average of the bid prices of all market makers for such security
as reported in the "pink sheets" by the National  Quotation Bureau,  Inc. If the
Closing Bid Price cannot be calculated for such security on any of the foregoing
bases,  the Closing Bid Price of such security shall be the fair market value as
reasonably  determined  by an  investment  banking firm  selected by the Holders
(which may be a Holder) of a majority of the then  outstanding  Preferred Shares
and reasonably  acceptable to the Corporation,  with the costs of such appraisal
to be borne by the  Corporation.  "Business  Day" means any day on which the New
York Stock  Exchange and  commercial  banks  located in the City of New York are
open for business.

         (e)  Delivery  of Common  Stock  Upon  Conversion.  Upon  receipt  of a
Conversion   Notice  from  a  Holder  pursuant  to  paragraph  4(b)  above,  the
Corporation  shall,  no later  than the close of  business  on the  third  (3rd)
Business Day following the Conversion Date set forth in such  Conversion  Notice
(the "Delivery Date"), issue and deliver or cause to be delivered to such Holder
the number of Conversion  Shares as shall be determined as provided herein.  The
Corporation  shall effect delivery of Conversion  Shares to a Holder by, as long
as the Transfer Agent  participates in the Depository Trust Company ("DTC") Fast
Automated  Securities  Transfer program ("FAST"),  crediting the account of such
Holder or its nominee at DTC through its  Deposit  Withdrawal  Agent  Commission
system with the number of Conversion  Shares required to be delivered,  no later
than the close of business on such  Delivery  Date.  In the event that  Transfer
Agent is not a  participant  in FAST or if a Holder so specifies in a Conversion
Notice or  otherwise  in  writing,  the  Corporation  shall  effect  delivery of
Conversion   Shares  by  delivering  to  the  Holder  or  its  nominee  physical
certificates  representing  such Conversion  Shares,  no later than the close of
business on such  Delivery  Date.  If any  Conversion  would create a fractional
Conversion Share, such fractional  Conversion Share shall be disregarded and the
number of Conversion  Shares  issuable upon such  Conversion,  in the aggregate,
shall  be the  next  higher  number  of  Conversion  Shares.  Conversion  Shares
delivered to the Holder shall not contain any restrictive  legend as long as (A)
the sale or  transfer  of such  Conversion  Shares is  covered  by an  effective
Registration  Statement,  (B) such Conversion  Shares have been sold pursuant to
Rule 144 ("Rule 144") under the Securities  Act, or (C) such  Conversion  Shares
are eligible for resale under Rule 144(k) or any successor rule or provision.

         (f) Failure to Deliver Conversion Shares.

                  (i) In the event that the Corporation  fails for any reason to
deliver to a Holder  certificates  representing the number of Conversion  Shares
specified in the  applicable  Conversion  Notice on or before the Delivery  Date
therefor (a  "Conversion  Default"),  and such failure  continues  for seven (7)
Business Days  following the Delivery Date,  the  Corporation  shall pay to such
Holder  payments  ("Conversion  Default  Payments") in the amount of (i) (N/365)
multiplied  by  (ii)  the  aggregate  Stated  Value  of the  Preferred  Share(s)
represented by the Conversion Shares which remain the subject of such Conversion
Default  multiplied  by (iii) the  lower of  twenty-four  percent  (24%) and the
maximum rate permitted by applicable law (the "Default  Interest  Rate"),  where
"N" equals the number of days  elapsed  between the original  Delivery  Date for
such  Conversion   Shares  and  the  date  on  which  all  of  the  certificates
representing  such  Conversion  Shares are issued and  delivered to such Holder.
Amounts  payable  under  this  subparagraph  (f) shall be paid to the  Holder in
immediately available funds on or before the fifth
                                      -4-
<PAGE>
(5th)  Business Day of the calendar  month  immediately  following  the calendar
month in which such amounts have accrued.

                  (ii) In the event that a Holder has not received  certificates
representing the Conversion  Shares by the tenth (10th) Business Day following a
Conversion Default, such Holder may, upon written notice (a "Withdrawal Notice")
delivered  to the  Corporation  on  such  Business  Day or on any  Business  Day
thereafter (unless, prior to the delivery of such notice, such Conversion Shares
are delivered to such Holder),  withdraw its  Conversion  Notice with respect to
such Conversion Shares and regain its rights as a Holder of the Preferred Shares
that are the subject of such Conversion  Default.  In such event, the Conversion
Price  that  would  otherwise  be in  effect  when  such  Preferred  Shares  are
thereafter converted in accordance with the terms hereof shall be reduced by one
percent (1%) for each day occurring during the period immediately following such
10th  Business Day until the day on which the such Holder  delivers a Withdrawal
Notice to the Corporation;  provided,  however,  that the maximum  percentage by
which such  Conversion  Price may be reduced  hereunder  shall be fifty  percent
(50%). (For example,  if such Conversion  Default were to continue for five days
following such 10th Business Day, such Conversion  Price would be reduced by 5%;
if for ten days, by 10%; and for fifty days or more,  50%, so that the number of
Conversion Shares  deliverable upon conversion of such Preferred Shares would be
increased  proportionately).  Upon delivery by a Holder of a Withdrawal  Notice,
such Holder shall retain all of such  Holder's  rights and remedies with respect
to the  Corporation's  failure  to deliver  such  Conversion  Shares  (including
without  limitation  the  right  to  receive  the  cash  payments  specified  in
subparagraph 4(f)(i) above).

                  (iii) In addition to any other remedies provided herein,  each
Holder  shall  have the right to pursue  actual  damages  for the  Corporation's
failure to issue and deliver  Conversion Shares on the applicable  Delivery Date
(including,  without  limitation,  damages relating to any purchase of shares of
Common Stock by such Holder to make delivery on a sale effected in  anticipation
of receiving Conversion Shares upon Conversion,  such damages to be in an amount
equal to (A) the  aggregate  amount paid by such Holder for the shares of Common
Stock so purchased minus (B) the aggregate  Conversion Price for such Conversion
Shares),  and such Holder shall have the right to pursue all remedies  available
to it at law or in equity (including,  without limitation,  a decree of specific
performance and/or injunctive relief).

         (g)  Conversion  at  Maturity.  On the date  which  is four  (4)  years
following the Issue Date relating to a Preferred Share ("Maturity  Date"),  such
Preferred  Share shall be  automatically  converted into the number of shares of
Common Stock equal to the Stated Value of such  Preferred  Shares divided by the
Conversion Price then in effect (a "Conversion at Maturity"); provided, however,
that  if,  on a  Maturity  Date,  (i) the  number  of  shares  of  Common  Stock
authorized,  unissued  and  unreserved  for all other  purposes,  or held in the
Corporation's treasury, is not sufficient to effect the issuance and delivery of
the number of Conversion Shares into which all outstanding  Preferred Shares are
then  convertible,  (ii) the Common Stock is not  actively  traded on the Nasdaq
National Market,  or (iii) a Mandatory  Redemption Event (as defined herein) has
occurred  and is  continuing,  each Holder  shall have the option,  upon written
notice to the Corporation, to regain its rights as a holder of Preferred Shares,
including  without  limitation,  the right to convert such  Preferred  Shares in
accordance  with the terms of  paragraphs  4(a)  through  4(f) hereof and,  upon
delivery  of such  notice,  such  Preferred  Shares  shall not be  subject  to a
Conversion at Maturity  hereunder  until the thirtieth  (30th) day following the
later of (a) the date on which  the  event  specified  (i),  (ii) or (iii) is no
longer  continuing  and (b) the date on which the  Corporation  delivers to each
Holder  written  notice to such effect,  and in such event,  such  thirtieth day
shall be deemed to be the  Maturity  Date for  purposes of this  Certificate  of
Designation. If a Conversion at Maturity occurs, the Corporation and each Holder
shall follow the procedures for Conversion set forth in this Section 4, with the
Maturity Date deemed 
                                      -5-
<PAGE>
to be the Conversion Date,  except that the Holder shall not be required to send
a Conversion Notice as contemplated by paragraph 4(b).

5. CONVERSION LIMITATIONS.

         In no event shall a Holder be permitted to convert any Preferred Shares
in excess of the number of such shares, upon the Conversion of which:

         (a) the  number of  Conversion  Shares to be  issued  pursuant  to such
Conversion,  when added to the number of shares of Common Stock issued  pursuant
to all  prior  Conversions  of  Preferred  Shares,  would  exceed  five  million
(5,000,000)  shares of Common Stock (subject to equitable  adjustments from time
to time for the events  described  in  paragraph  6 below)  (the "Cap  Amount"),
except that such  limitation  shall not apply in the event that the  Corporation
obtains the approval of a majority of its  stockholders  for issuances of Common
Stock in excess of such amount. Until such approval is obtained, no purchaser of
Preferred  Shares  pursuant  to  the  Securities  Purchase  Agreement  (each,  a
"Purchaser" and together the "Purchasers")  shall be issued,  upon Conversion of
the Preferred Shares, Conversion Shares in an amount greater than the product of
(A) the Cap Amount times (B) a fraction, the numerator of which is the number of
Preferred  Shares issued to such Purchaser  pursuant to the Securities  Purchase
Agreement and the  denominator  of which is the  aggregate  amount of all of the
Preferred  Shares issued to the Purchasers  pursuant to the Securities  Purchase
Agreement (the "Allocation  Amount"). In the event that any Purchaser shall sell
or otherwise  transfer any of such Purchaser's  Preferred Shares, the transferee
shall  be  allocated  a pro  rata  portion  of  the  remaining  unissued  shares
constituting  such Purchaser's  Allocation  Amount. In the event that any Holder
shall convert all of such Holder's  Preferred Shares into a number of Conversion
Shares which, in the aggregate,  is less than such Holder's  Allocation  Amount,
then the difference  between such Holder's  Allocation  Amount and the number of
Conversion  Shares  actually  issued to such Holder  shall be  allocated  to the
respective  Allocation Amounts of the remaining Holders of Preferred Shares on a
pro rata basis in proportion to the number of Preferred Shares then held by each
such Holder.  In the event that any Holder's  Allocation  Amount  represents one
hundred and fifty percent (150%) or less of (A) the number of Conversion  Shares
into which the Preferred  Shares then held by such Holder are convertible at the
Conversion  Price  then in effect  (without  regard to any  restriction  on such
conversion  that may exist  pursuant to the terms  hereof or of any  Transaction
Document)  plus (B) the number of  Conversion  Shares into which such Holder has
previously  converted  Preferred  Shares,  such  Holder  shall have the right to
require the  Corporation,  upon written  notice  delivered by such Holder to the
Corporation, to, within five (5) days following the date on which such notice is
delivered to the Corporation, either (i) redeem all of the Preferred Shares then
held by such Holder by delivering to such Holder immediately  available funds in
an amount equal to the  Conversion  Cap  Redemption  Price (as defined below) or
(ii) give written notice to each Holder that the Corporation  will, within sixty
(60) days of such  Conversion  Date,  obtain the  approval of the  Corporation's
stockholders for the issuance of Conversion  Shares in excess of the Cap Amount.
In the event that the  Corporation  does not obtain  such  stockholder  approval
prior to such sixtieth day, each Holder shall have the right,  exercisable  from
time to time, upon written notice to the Corporation, to require the Corporation
to redeem all or any part of such Holder's Preferred Shares within five (5) days
following  the receipt by the  Corporation  of such notice by delivering to such
Holder  immediately  available  funds in an amount equal to the  Conversion  Cap
Redemption  Price. Any amounts  representing the Conversion Cap Redemption Price
which are not paid when due shall bear  interest  at an annual rate equal to the
Default  Interest  Rate. For purposes  hereof,  the  "Conversion  Cap Redemption
Price" with respect to a Preferred  Share shall be equal to (a) during the first
three  hundred and sixty (360) days  following  the Issue Date  relating to such
Preferred  Share,  108.5% of the Stated  Value of such  Preferred  Share and (b)
following the last day of such three hundred and sixtieth
                                      -6-
<PAGE>
day  period,  a price that is  calculated  so that the Holder of such  Preferred
Share will receive an  annualized  return on the Stated Value of such  Preferred
Share of 8.5%; and

         (b) (x) the number of shares of Common Stock beneficially owned by such
Holder (other than shares of Common Stock issuable upon  conversion of Preferred
Shares or which would  otherwise be deemed  beneficially  owned except for being
subject to a limitation on conversion  or exercise  analogous to the  limitation
contained  in this  subparagraph  (b))  plus (y) the  number of shares of Common
Stock issuable upon the Conversion of such Preferred  Shares,  would be equal to
or exceed  (z) 4.99% of the  number of shares of Common  Stock  then  issued and
outstanding.  As used  herein,  beneficial  ownership  shall  be  determined  in
accordance  with  Section  13(d) of the  Securities  Exchange  Act of  1934,  as
amended,  and the rules thereunder.  To the extent that the limitation contained
in this paragraph 5(b) applies,  the  determination of whether  Preferred Shares
are convertible (in relation to other securities owned by a Holder) and of which
Preferred Shares are convertible shall be in the sole discretion of such Holder,
and the submission of Preferred Shares for Conversion shall be deemed to be such
Holder's  determination  that such Preferred Shares are convertible  pursuant to
the terms hereof,  and the  Corporation  shall have no obligation  whatsoever to
verify or confirm the  accuracy of such  determination.  This  paragraph  may be
amended (i) in order to clarify an ambiguity or otherwise to give effect to such
limitation,  by the Holders of  two-thirds  (2/3) of the  Preferred  Shares then
outstanding  and (ii) for any other  reason,  with the  further  consent  of the
holders of a majority of the shares of Common  Stock then  outstanding.  Nothing
contained  herein  shall be deemed to restrict  the right of a Holder to convert
Preferred  Shares at such time as the  Conversion  thereof  will not violate the
provisions  of  this  subparagraph  5(b).  The  restriction  contained  in  this
subparagraph 5(b) shall not apply in the event of a Conversion at Maturity or to
a Holder  delivering  a Mandatory  Redemption  Notice (as defined  below) on the
seventy  fifth  (75th) day  following  the date on which such Holder  delivers a
notice  to the  Corporation  that such  restriction  shall  not  apply,  and may
otherwise  be  irrevocably  amended by any Holder with respect to itself so that
such limit shall be 9.99% instead of 4.99%  following at least seventy five (75)
days' prior written notice by such Holder to the Corporation.

6. ADJUSTMENTS TO CONVERSION PRICE.

         (a)  Adjustment  to Fixed  Conversion  Price Due to Stock Split,  Stock
Dividend,  Etc. If, prior to the Conversion of all of the Preferred Shares,  (A)
the number of outstanding  shares of Common Stock is increased by a stock split,
a stock  dividend on the Common Stock, a  reclassification  of the Common Stock,
the distribution to holders of Common Stock of rights or warrants entitling them
to subscribe for or purchase  Common Stock at less than the then current  market
price thereof (based upon the  subscription  or exercise price of such rights or
warrants at the time of the issuance  thereof) or other similar event, the Fixed
Conversion  Price  shall  be  proportionately  reduced,  or (B)  the  number  of
outstanding  shares of Common  Stock is  decreased  by a  reverse  stock  split,
combination  or  reclassification  of shares or other similar  event,  the Fixed
Conversion  Price  shall  be  proportionately  increased.  In  such  event,  the
Corporation  shall  notify the  Transfer  Agent of such  change on or before the
effective  date  thereof.  For  purposes  hereof,  the market price per share of
Common  Stock on any date shall be the average  Closing Bid Price for the Common
Stock on the five (5) consecutive  Trading Days occurring  immediately  prior to
but not  including  the earlier of such date and the Trading Day before the "ex"
date,  if any,  with  respect to the  issuance or  distribution  requiring  such
computation.  The term "'ex'  date",  when used with  respect to any issuance or
distribution,  means the first  Trading  Day on which the  Common  Stock  trades
regular way in the market from which such  average  Closing Bid Price is then to
be determined without the right to receive such issuance or distribution.
                                      -7-
<PAGE>
         (b) Adjustment to Conversion Price During Reference  Period.  If, prior
to the  Conversion of all of the  Preferred  Shares,  the number of  outstanding
shares of Common Stock is  increased  or  decreased  by a stock  split,  a stock
dividend on the Common Stock, a combination,  a  reclassification  of the Common
Stock or other  similar  event,  and such event takes place during the reference
period for the determination of the Conversion Price for any Conversion thereof,
the Conversion Price shall be calculated giving  appropriate effect to the stock
split, stock dividend, combination,  reclassification or other similar event for
all Trading Days occurring during such reference period.

         (c)  Adjustment  Due to Merger,  Consolidation,  Etc.  If, prior to the
Conversion  of  all  of  the  Preferred  Shares,  there  shall  be  any  merger,
consolidation,   business   combination,   tender  offer,  exchange  of  shares,
recapitalization, reorganization, redemption or other similar event, as a result
of which shares of Common Stock shall be changed into or exchanged  for the same
or a different number of shares of the same or another class or classes of stock
or securities of the Corporation or another entity (an "Exchange  Transaction"),
then such Holder shall (A) upon the closing of such Exchange  Transaction,  have
the right to receive,  with  respect to any shares of Common  Stock then held by
such  Holder,  or which such Holder is then  entitled  to receive  pursuant to a
Conversion  Notice previously  delivered by such Holder,  (and without regard to
whether such shares contain a restrictive  legend or are  freely-tradeable)  the
same amount and type of  consideration  (including  without  limitation,  stock,
securities  and/or other  assets) and on the same terms as a holder of shares of
Common Stock would be entitled to receive in connection with the consummation of
such  Exchange  Transaction  (the  "Exchange  Consideration"),  and (B) upon the
Conversion of Preferred  Shares occurring on a Conversion Date subsequent to the
closing of such  Exchange  Transaction,  have the right to receive the  Exchange
Consideration  which  such  Holder  would  have  been  entitled  to  receive  in
connection  with  such  Exchange  Transaction  had such  shares  been  converted
immediately prior to such Exchange Transaction at the Conversion Price in effect
on such Conversion  Date, and in any such case  appropriate  provisions shall be
made with respect to the rights and interests of such Holder to the end that the
provisions hereof (including, without limitation,  provisions for the adjustment
of the Conversion  Price and of the number of shares issuable upon a Conversion)
shall  thereafter be applicable as nearly as may be  practicable  in relation to
any  securities  thereafter  deliverable  upon the  Conversion of such Preferred
Shares. The Corporation shall not effect any Exchange  Transaction unless (i) it
first gives to each Holder twenty (20) days prior written  notice of the closing
of such  Exchange  Transaction  (an  "Exchange  Notice"),  and  makes  a  public
announcement  of such event at the same time that it gives such  notice and (ii)
the resulting successor or acquiring entity (if not the Corporation)  assumes by
written instrument the obligations of the Corporation  hereunder,  including the
terms of this subparagraph 6(c), and under the Securities Purchase Agreement and
related the  Registration  Rights Agreement by and among the Corporation and the
Purchasers named therein (the "Registration Rights Agreement").

         (d)  Distribution  of  Assets.   If  the  Corporation  or  any  of  its
subsidiaries  shall  declare  or make any  distribution  of cash,  evidences  of
indebtedness  or other  securities  or  assets  (other  than cash  dividends  or
distributions  payable out of earned surplus for the current or the  immediately
preceding  year),  or any  rights to  acquire  any of the  foregoing  (including
without  limitation  any rights  distributed  pursuant  to the  Rights  Plan (as
defined in the Securities Purchase  Agreement)),  to holders of Common Stock (or
to a holder of the common stock of any such subsidiary),  including any dividend
or  distribution  in shares of capital stock of a subsidiary of the  Corporation
(collectively,  a "Distribution"),  each Holder shall have the right to receive,
on the date such Distribution is made (the  "Distribution  Date"), the amount of
the Distribution allocated to each share of Common Stock (or common stock of any
such  subsidiary)  times the  number of shares  of Common  Stock  issuable  upon
conversion of the Preferred Shares held by such Holder on the Distribution Date,
assuming for such purpose that such Preferred Shares are
                                      -8-
<PAGE>
convertible (regardless of whether any restriction on the ability of such Holder
to  convert  such  Preferred  Shares  then  applies)  at  the  Conversion  Price
applicable on the Distribution Date.

         (e) Adjustment Due to Major Announcement.  If the Corporation (i) makes
a public  announcement  that it  intends  to  enter  into a  Change  of  Control
Transaction  (as defined below) or (ii) any person,  group or entity  (including
the  Corporation)  publicly  announces a tender offer,  exchange  offer or other
transaction to purchase 50% or more of the Common Stock (such announcement being
referred  to  herein  as a  "Major  Announcement"  and the date on which a Major
Announcement is made, the "Announcement Date"), then, in the event that a Holder
seeks to convert  Preferred  Shares on or following the  Announcement  Date, the
Conversion  Price shall,  effective  upon the  Announcement  Date and continuing
through  the fifth  (5th)  Business  Day  following  the earlier to occur of the
consummation  of the proposed  transaction  or tender offer,  exchange  offer or
other  transaction and the Abandonment Date (as defined below),  be equal to the
lower of (x) the average  Closing Bid Price for the Common Stock on the five (5)
Trading Days immediately preceding (but not including) the Announcement Date and
(y) the  Conversion  Price that would  otherwise be in effect on the  Conversion
Date for such  Preferred  Shares.  "Abandonment  Date" means with respect to any
proposed  transaction or tender offer,  exchange offer or other  transaction for
which a public  announcement  as  contemplated  by this  paragraph 6(e) has been
made, the date upon which the  Corporation  (in the case of clause (i) above) or
the  person,  group  or  entity  (in the case of  clause  (ii)  above)  publicly
announces the  termination or abandonment of the proposed  transaction or tender
offer, exchange offer or another transaction which caused this paragraph 6(e) to
become operative.

         (f) Adjustment Pursuant to Other Agreements. In addition to and without
limiting in any way the  adjustments  provided in this Section 6, the Conversion
Price shall be adjusted as may be required by the provisions of the Registration
Rights Agreement and/or by the provisions of the Securities Purchase Agreement.

         (g) No Fractional  Shares.  If any adjustment  under this Section would
create a  fractional  share of Common  Stock or a right to acquire a  fractional
share of Common Stock, such fractional share shall be disregarded and the number
of shares of Common  Stock  issuable  upon  Conversion  shall be the next higher
number of shares or, at the option of the Corporation,  shall be paid in cash in
an amount calculated by multiplying the amount of the fractional share times the
Closing Bid Price used to calculate the Conversion Price for such Conversion.

7. MANDATORY REDEMPTION BY HOLDER.

         (a)  Mandatory  Redemption.  In the event that a  Mandatory  Redemption
Event (as defined below) occurs, each Holder shall have the right to require the
Corporation  to redeem all or any portion of the  Preferred  Shares held by such
Holder (a "Mandatory  Redemption") at the Mandatory Redemption Price (as defined
herein) in same day funds.  In order to exercise its right to effect a Mandatory
Redemption,  a Holder must  deliver a written  notice (a  "Mandatory  Redemption
Notice") to the  Corporation at any time on or before the Business Day following
the day on which such event is no longer continuing; provided, however, that, in
the case of subparagraph (b)(v) below, the following procedure shall be followed
in lieu  thereof:  (a) no sooner than  fifteen (15) days nor later than ten (10)
days prior to the  Corporation's  good faith estimate of the  consummation  of a
Change of Control  Transaction (as defined  below),  but not prior to the public
announcement  of such  Change of  Control  Transaction,  the  Corporation  shall
deliver a written notice (a "Notice of Change of Control  Transaction")  to each
Holder,  and (b) within five (5) days of delivery by the Corporation of a Notice
of Change of Control  Transaction,  each Holder who wishes to exercise its right
to effect a Mandatory  Redemption hereunder shall deliver a Mandatory Redemption
Notice to the  Corporation.  The Mandatory  Redemption  Notice shall specify the
effective date of such Mandatory Redemption (the
                                      -9-
<PAGE>
"Mandatory  Redemption  Date") and the number of such shares to be redeemed.  In
the event that a Change of Control  Transaction  occurs and the Corporation does
not  deliver  to a Holder a Notice of Change of Control  Transaction  within the
time periods  described above, such Holder may exercise its right to a Mandatory
Redemption  hereunder  by  delivering  a  Mandatory  Redemption  Notice  to  the
Corporation  (or to the surviving or successor  entity) at any time on or before
the twentieth (20th) Business Day following such Change of Control Transaction.

         (b) Mandatory  Redemption  Event. Each of the following events shall be
deemed a "Mandatory Redemption Event":

                  (i) the Corporation  fails for any reason  (including  without
limitation  as a result of not  having a  sufficient  number of shares of Common
Stock  authorized  and reserved for issuance,  or as a result of the  limitation
contained  in Section  5(a)  hereof) to issue shares of Common Stock to a Holder
and  deliver  certificates  representing  such shares to such Holder as and when
required by the provisions hereof upon Conversion of any Preferred  Shares,  and
such failure continues for twenty (20) Business Days;

                  (ii) the  Corporation  breaches,  in a material  respect,  any
covenant or other material term or condition of this Certificate, the Securities
Purchase Agreement,  the Registration Rights Agreement,  or any other agreement,
document,  certificate  or other  instrument  delivered in  connection  with the
transactions  contemplated  thereby,  and such breach  continues for a period of
fifteen (15) Business Days after written notice thereof to the Corporation  from
a Holder;

                  (iii) the Registration  Statement is not declared effective by
the one hundred and eightieth (180th) day following the Initial Issue Date or if
the Registration  Statement has been declared  effective by such date and, while
the  effectiveness  of the  Registration  Statement is required to be maintained
pursuant to the terms of the Registration Rights Agreement, the effectiveness of
the Registration  Statement lapses for any reason (including without limitation,
the  issuance of a stop order) or is  unavailable  to the Holder for the sale of
Conversion  Shares  in  accordance  with the  terms of the  Registration  Rights
Agreement,  and such lapse or unavailability  continues for a period of five (5)
Business Days,  provided that the cause of such lapse or  unavailability  is not
due to factors solely within the control of the Holder;

                  (iv) the  Corporation  fails to obtain either (A) the approval
of  stockholders  described in paragraph 5(a) above on or before the time frames
set forth in  paragraph  5(a) to obtain  such  approval  or (B) the  approval of
stockholders  described in paragraph  4.15 or paragraph  4.16 of the  Securities
Purchase  Agreement  on or before on or before the time frames set forth in such
paragraph 4.15 or 4.16;

                  (v)  the  Corporation   undertakes  any  voluntary  action  to
terminate  the  quotation or listing of the Common Stock on the Nasdaq  National
Market or on any national securities exchange; and

                  (vi) there occurs the sale,  conveyance or  disposition of all
or substantially all of the assets of the Corporation or any of its subsidiaries
(including  without  limitation the sale or other conveyance of any common stock
or other equity  securities of any of the  Corporation's  subsidiaries),  or the
effectuation of a transaction or series of related  transactions,  in which more
than  50% of the  voting  power  of  the  Corporation  is  disposed  of,  or the
consolidation, merger or other business combination of the Corporation or any of
its subsidiaries with or into any other entity,  immediately following which the
prior  stockholders of the Corporation fail to own,  directly or indirectly,  at
least  fifty  percent  (50%) of the  surviving  entity  (a  "Change  of  Control
Transaction"),  provided,  however, that a tender offer or any other transaction
with respect to
                                      -10-
<PAGE>
which the Corporation's  Board of Directors is unable to exercise  discretion as
to the  effectuation  thereof  shall  not be deemed to  constitute  a  Mandatory
Redemption Event by operation of this subparagraph (vi).

         (c) Mandatory Redemption Price. The "Mandatory  Redemption Price" shall
be equal to the greater of (i)  Liquidation  Preference of the Preferred  Shares
being redeemed  multiplied by one hundred and seventeen  percent (117%) and (ii)
an amount  determined by dividing the Stated Value of the Preferred Shares being
redeemed by the Conversion Price in effect on the Mandatory  Redemption Date and
multiplying  the  resulting  quotient by the  average  Closing Bid Price for the
Common  Stock  on the five  (5)  Trading  Days  immediately  preceding  (but not
including) the Mandatory Redemption Date.

         (d) Payment of Mandatory Redemption Price.

                  (i) The Corporation  shall pay the Mandatory  Redemption Price
to the Holder  exercising  its right to  redemption on the later to occur of (i)
the fifth (5th)  Business Day following the Mandatory  Redemption  Date and (ii)
the date on which the  Preferred  Shares  being  redeemed  are  delivered by the
Purchaser to the Corporation for cancellation.

                  (ii) If  Corporation  fails  to pay the  Mandatory  Redemption
Price to the Holder within five (5) Business  Days of the  Mandatory  Redemption
Date,  the Holder  shall be  entitled to  interest  thereon,  from and after the
Mandatory  Redemption Date until the Mandatory Redemption Price has been paid in
full, at an annual rate equal to the Default Interest Rate.

                  (iii) If the Corporation fails to pay the Mandatory Redemption
Price within ten (10) Business Days of the Mandatory  Redemption  Date, then the
Holder shall have the right at any time, so long as the  Corporation  remains in
default, to require the Corporation,  upon written notice, to immediately issue,
in lieu of the Mandatory  Redemption Price, the number of shares of Common Stock
of the  Corporation  equal to the  Mandatory  Redemption  Price  divided  by the
Conversion Price in effect on such Conversion Date as is specified by the Holder
in  writing  to the  Corporation,  such  Conversion  Price to be  reduced by one
percent (1%) for each day beyond such 10th  Business Day in which the failure to
pay the  Mandatory  Redemption  Price  continues;  provided,  however,  that the
maximum percentage by which such Conversion Price may be reduced hereunder shall
be fifty percent (50%).

         (e) Modification of Mandatory Redemption Provisions.  The terms of this
Section 7 shall apply to the Series B Preferred  Stock until such time,  if any,
as such  terms  have  been  superseded,  in whole or in part,  by the terms of a
Determination  Certificate (as defined  below).  A  "Determination  Certificate"
shall be a written instrument containing redemption provisions applicable to the
Series B  Preferred  Stock (or  affirming  the  absence of any such  provisions)
proposed by the Holders of a majority of the shares of Series B Preferred  Stock
at the time  outstanding  and duly adopted by the Board of  Directors,  provided
that the approval of the Board of  Directors  shall be deemed to be given if the
adopting  Holders furnish the Corporation  with a certificate to the effect that
the Determination Certificate reflects a determination made in consultation with
the Corporation's auditors or another firm of accountants of recognized national
standing  that the changes  contemplated  thereby are  necessary  to qualify the
Series B  Preferred  Stock as  stockholders'  equity  under  generally  accepted
accounting principles. The Corporation shall promptly give written notice of the
adoption  of any  Determination  Certificate  to all  holders  of its  Series  B
Preferred Stock,  shall refer to the existence of any Determination  Certificate
in its annual  financial  statements  and shall supply to any  stockholder  upon
request the full text thereof.  One or more  Determination  Certificates  may be
adopted pursuant to this paragraph. The contents of a Determination  Certificate
shall be deemed to be  "facts"  for  purposes  of  Section  151 of the  Delaware
General Corporation Law.

8. MISCELLANEOUS.

         (a) Transfer of Preferred  Shares. A Holder may sell or transfer all or
any portion of the Preferred Shares to any person or entity as long as such sale
or transfer  is the subject of an  effective  registration  statement  under the
Securities Act or is exempt from  registration  thereunder and otherwise is made
in accordance  with the terms of the  Securities  Purchase  Agreement.  From and
after the date of such sale or transfer,  the transferee thereof shall be deemed
to be a Holder. Upon any such sale or transfer,  the Corporation shall, promptly
following  the  return  of the  certificate  or  certificates  representing  the
Preferred  Shares  that are the  subject  of such  sale or  transfer,  issue and
deliver to such transferee a new certificate in the name of such transferee.

         (b) Notices. Except as otherwise provided herein, any notice, demand or
request required or permitted to be given pursuant to the terms hereof, the form
or  delivery  of which  notice,  demand or  request is not  otherwise  specified
herein,  shall be in  writing  and  shall be  deemed  given  (i) when  delivered

and if to any Holder,  to such address for such Holder as shall be designated by
such Holder in writing to the Corporation.

         (c) Lost or Stolen  Certificate.  Upon  receipt by the  Corporation  of
evidence  of  the  loss,  theft,  destruction  or  mutilation  of a  certificate
representing  Preferred Shares,  and (in the case of loss, theft or destruction)
of indemnity reasonably satisfactory to the Corporation,  and upon surrender and
cancellation of such certificate if mutilated, the Corporation shall execute and
deliver  to the  Holder  a new  certificate  identical  in all  respects  to the
original certificate.

         (d) No  Voting  Rights.  Except  as  provided  by  applicable  law  and
paragraph 8(g) below,  the Holders of the Preferred  Shares shall have no voting
rights with respect to the
                                      -12-
<PAGE>
business,   management  or  affairs  of  the  Corporation;   provided  that  the
Corporation shall provide each Holder with prior notification of each meeting of
stockholders  (and copies of proxy statements and other information sent to such
stockholders).

         (e)  Remedies,   Characterization,   Other  Obligations,  Breaches  and
Injunctive  Relief.  The remedies  provided to a Holder in this  Certificate  of
Designation shall be cumulative and in addition to all other remedies  available
to such Holder under this  Certificate of  Designation or under any  Transaction
Document (as defined in the Securities Purchase Agreement),  at law or in equity
(including  without  limitation  a decree of specific  performance  and/or other
injunctive  relief),  no  remedy  contained  herein  shall be deemed a waiver of
compliance with the provisions  giving rise to such remedy and nothing contained
herein shall limit such Holder's  right to pursue actual damages for any failure
by the Corporation to comply with the terms of this  Certificate of Designation.
The Corporation agrees with each Holder that there shall be no  characterization
concerning this instrument other than as specifically  provided herein.  Amounts
set forth or provided for herein with respect to  payments,  conversion  and the
like (and the  computation  thereof)  shall be the amounts to be received by the
Holder hereof and shall not, except as expressly  provided herein, be subject to
any other  obligation  of the  Corporation  (or the  performance  thereof).  The
Corporation  acknowledges that a breach by it of its obligations  hereunder will
cause  irreparable  harm to the  Holders and that the remedy at law for any such
breach  may be  inadequate.  The  Corporation  agrees,  in the event of any such
breach or threatened breach,  each Holder shall be entitled,  in addition to all
other available remedies, to an injunction  restraining any breach,  without the
necessity of showing  economic loss and without any bond or other security being
required.

         (f) Failure or Delay not  Waiver.  No failure or delay on the part of a
Holder in the exercise of any power, right or privilege  hereunder shall operate
as a waiver thereof, nor shall any single or partial exercise of any such power,
right or privilege  preclude other or further  exercise  thereof or of any other
right, power or privilege.

         (g) Protective Provisions.

                  So long as shares of Series B Preferred Stock are outstanding,
the Corporation  shall not,  without first obtaining the approval of the Holders
of at  least  two-thirds  (2/3)  of the  then  outstanding  shares  of  Series B
Preferred Stock:

                           (i)  alter  or  change  the  rights,  preferences  or
privileges  of the Series B Preferred  Stock or any other  capital  stock of the
Corporation so as to affect adversely the Series B Preferred Stock;

                           (ii) create any new class or series of capital  stock
having a preference over or ranking pari passu with the Series B Preferred Stock
as to redemption or distribution of assets upon a Liquidation Event or any other
liquidation, dissolution or winding up of the Corporation;

                           (iii)  increase  the  authorized  number of shares of
Preferred Stock;

                           (iv) re-issue any shares of Series B Preferred  Stock
which have been converted or redeemed in accordance with the terms hereof;

                           (v)  issue  any  Pari  Passu   Securities  or  Senior
Securities (other than (x) shares of Series B Preferred Stock issued pursuant to
the Securities Purchase Agreement, (y) debt securities which are not convertible
into or  exchangeable  for  Common  Stock or any  other  equity  or  convertible
security of the Corporation, or (z) the issuance of Series A Preferred Stock
                                      -13-
<PAGE>
of the  Company  pursuant  to the  Rights  Plan (as  defined  in the  Securities
Purchase Agreement) in effect as of the date hereof); or

                           (vi) redeem,  or declare,  pay or make any  provision
for any dividend or distribution  with respect to, the Common Stock or any other
capital stock of the Corporation  ranking junior to the Series B Preferred Stock
as to the distribution of assets upon liquidation,  dissolution or winding up of
the Corporation  (other than a dividend to be paid from and after the end of the
two (2) year period  following  the later to occur of the Tranche A Closing Date
and the  Tranche B Closing  Date  (each as defined  in the  Securities  Purchase
Agreement)  to  holders  of  Common  Stock  out  of  retained  earnings  of  the
Corporation that have accrued during the prior fiscal year.

         In the event  that  Holders  of at least  two-thirds  (2/3) of the then
outstanding shares of Series B Preferred Stock agree to allow the Corporation to
alter or change the rights,  preferences or privileges of the shares of Series B
Preferred Stock, pursuant to the terms hereof, then the Corporation will deliver
notice of such  approved  change to the holders of the Series B Preferred  Stock
that did not agree to such alteration or change (the  "Dissenting  Holders") and
the  Dissenting  Holders  shall have the right for a period of thirty  (30) days
following such delivery to convert their Preferred  Shares pursuant to the terms
hereof as they existed  prior to such  alteration  or change,  or to continue to
hold such  Preferred  Shares.  No such change  shall be  effective to the extent
that,  by its terms,  it applies  to less than all of the  Holders of  Preferred
Shares then outstanding.

                        WARRANT TO PURCHASE COMMON STOCK

                                       of

                                ORTHOLOGIC CORP.


     THIS  CERTIFIES  that  ________________________  or any  subsequent  holder
hereof  (the  "Holder"),  has the right to purchase  from  OrthoLogic  Corp.,  a
Delaware  corporation  (the  "Company"),   up  to  ___________  fully  paid  and
nonassessable  shares of the Company's Common Stock, par value $0.0005 per share
(the "Common Stock"), subject to adjustment as provided herein, at a price equal
to the Exercise Price (as defined  below),  at any time beginning on the date on
which this Warrant is issued (the "Issue Date") and ending at 5:00 p.m., eastern
time, on July 13, 2003 (the "Expiration  Date"). This Warrant is issued, and all
rights  hereunder  shall be, subject to all of the  conditions,  limitations and
provisions set forth herein and in the Securities Purchase Agreement.
<PAGE>
         1. Exercise.

         (a) Right to Exercise;  Exercise Price. The Holder shall have the right
to exercise  this Warrant at any time and from time to time up to and  including
the Expiration  Date as to all or any part of the shares of Common Stock covered
hereby (the "Warrant  Shares").  The "Exercise  Price"  payable by the Holder in
connection  with the exercise of this Warrant  shall be $5.50.

         (b) Exercise  Notice.  In order to exercise  this  Warrant,  the Holder
shall send by facsimile  transmission,  at any time prior to 11:59 p.m., eastern
time,  on the date on which  the  Holder  wishes to effect  such  exercise  (the
"Exercise  Date"),  to the Company and to its designated  transfer agent for the
Common Stock (the "Transfer Agent") a copy of the notice of exercise in the form
attached  hereto as  Exhibit A (the  "Exercise  Notice")  stating  the number of
Warrant Shares as to which such exercise  applies and the calculation  therefor.
The Holder shall thereafter deliver to the Company the original Exercise Notice,
the original  Warrant and the Exercise Price. In the case of a dispute as to the
calculation  of the  Exercise  Price or the  number of Warrant  Shares  issuable
hereunder,  the Company shall promptly issue to the Holder the number of Warrant
Shares that are not disputed and shall submit the disputed  calculations  to the
Company's  independent  accountant  within one (1)  business day  following  the
Exercise Date. The Company shall cause such accountant to calculate the Exercise
Price and/or the number of Warrant Shares  issuable  hereunder and to notify the
Company and the Holder of the results in writing no later than two (2)  business
days  following  the day on which it received  the disputed  calculations.  Such
accountant's  calculation  shall be deemed conclusive absent manifest error. The
fees of any such accountant shall be borne by the party whose  calculations were
most at variance with those of such accountant.

         (c)  Cancellation  of Warrant.  This Warrant shall be canceled upon its
exercise  and the Holder  shall be entitled to receive,  as soon as  practicable
after the Exercise Date, a new Warrant or Warrants  (containing  terms identical
to this Warrant) representing any unexercised portion of this Warrant.

         2. Delivery of Warrant Shares Upon Exercise. Upon receipt of a Exercise
Notice  pursuant to paragraph 1 above,  the Company shall,  (A) in the case of a
Cashless Exercise (as defined below), no later than the close of business on the
third (3rd)  business day following the Exercise Date set forth in such Exercise
Notice,  (B) in the case of a Cash Exercise (as defined below) no later than the
close of business on the  earlier to occur of (i) the third (3rd)  business  day
following  the  Exercise  Date set forth in such  Exercise  Notice and (ii) such
later date on which the  Company  shall have  received  payment of the  Exercise
Price, and (C) with respect to Warrant Shares which are disputed as described in
paragraph  1(b) above,  and required to be delivered by the Company  pursuant to
the accountant's  calculations  described therein,  the third (3rd) business day
following  the date on which  the  Company  has  received  the  notice  from its
accountants  described in such paragraph 1(b) (the "Delivery  Date"),  issue and
                                      -2-
<PAGE>
deliver or caused to be delivered to the Holder the number of Warrant  Shares as
shall be determined as provided  herein.  Warrant Shares delivered to the Holder
shall not contain  any  restrictive  legend as long as the sale of such  Warrant
Shares is covered by an  effective  Registration  Statement  (as  defined in the
Registration  Rights Agreement) or may be made pursuant to Rule 144(k) under the
Securities Act of 1933, as amended, or any successor rule or provision.

         3. Failure to Deliver Warrant Shares.

                  (a) Exercise Default.  In the event that the Company fails for
any reason (other than by operation of paragraph 4 below) to deliver to a Holder
certificates  representing  the  number  of  Warrant  Shares  specified  in  the
applicable Exercise Notice on or before the seventh (7th) business day following
the Delivery  Date therefor (an  "Exercise  Default"),  the Company shall pay to
such Holder payments  ("Exercise Default Payments") in the amount of (i) (N/365)
multiplied by (ii) the aggregate Exercise Price for the Warrant Shares which are
the  subject  of  such  Exercise  Default  multiplied  by  (iii)  the  lower  of
twenty-four  percent  (24%) and the maximum rate  permitted by  applicable  law,
where "N" equals the number of days elapsed  between the original  Delivery Date
for such  Warrant  Shares and the date on which all of such  Warrant  Shares are
issued and delivered to such Holder.  Amounts  payable  under this  subparagraph
3(a) shall be paid to the Holder in immediately available funds on or before the
fifth  (5th)  business  day of the  calendar  month  immediately  following  the
calendar month in which such amount has accrued.

                  (b)  Reduction of Exercise  Price.  In the event that a Holder
has not  received  certificates  representing  the  Warrant  Shares by the tenth
(10th) Business Day following an Exercise Default, such Holder may, upon written
notice to the  Company,  regain on such  business  day the rights of a Holder of
this Warrant,  or part thereof,  with respect to the Warrant Shares that are the
subject of such Exercise Default, and the Exercise Price for such Warrant Shares
shall be reduced by one percent (1%) for each day beyond such 10th  business day
in which the Exercise Default continues. In such event, such Holder shall retain
all of such Holder's  rights and remedies with respect to the Company's  failure
to deliver  such  Warrant  Shares  (including  without  limitation  the right to
receive the cash payments specified in subparagraph 3(a) above).

                  (c) Buy-in.  Nothing  herein  shall limit a Holder's  right to
pursue  actual  damages for the Company's  failure to issue and deliver  Warrant
Shares  in  connection  with  an  exercise  on  the  applicable   Delivery  Date
(including,  without  limitation,  damages relating to any purchase of shares of
Common Stock by such Holder to make delivery on a sale effected in  anticipation
of receiving Warrant Shares upon exercise, such damages to be in an amount equal
to (A) the  aggregate  amount paid by such Holder for the shares of Common Stock
so purchased minus (B) the aggregate amount of net proceeds, if any, received by
such Holder from the sale of the Warrant  Shares issued by the Company  pursuant
to such  exercise),  and such Holder shall have the right to pursue all remedies
available to it at law or in equity (including,  without limitation, a decree of
specific performance and/or injunctive relief).

                  (d) Holder of Record. Each Holder shall, for all purposes,  be
deemed to have
                                      -3-
<PAGE>
become  the  holder of record of  Warrant  Shares on the  Exercise  Date of this
Warrant, irrespective of the date of delivery of such Warrant Shares. Nothing in
this Warrant shall be construed as conferring  upon the Holder hereof any rights
as a stockholder of the Company.

         4. Exercise Limitations.

         In no event shall a Holder be permitted to exercise  this  Warrant,  or
part  thereof,  with  respect to Warrant  Shares in excess of the number of such
shares,  upon the  issuance of which,  (x) the number of shares of Common  Stock
beneficially  owned by such  Holder and its  affiliates  (other  than  shares of
Common  Stock  issuable  upon  exercise  of  the  Warrants  or the  exercise  or
conversion of securities  which contain a limitation  similar to the  limitation
contained  herein) plus (y) the number of shares of Common Stock  issuable  upon
such exercise,  would be equal to or exceed (z) 4.99% of the number of shares of
Common Stock then issued and outstanding.  As used herein,  beneficial ownership
shall be determined in accordance with Section 13(d) of the Securities  Exchange
Act of 1934,  as  amended,  and the rules  thereunder.  To the  extent  that the
limitation  contained in this paragraph 4 applies,  the determination of whether
this Warrant is exercisable (in relation to other  securities owned by a Holder)
shall  be in the  sole  discretion  of such  Holder,  and the  submission  of an
Exercise  Notice  shall be deemed to be such  Holder's  determination  that this
Warrant is exercisable  pursuant to the terms hereof, and the Company shall have
no   obligation   whatsoever   to  verify  or  confirm  the   accuracy  of  such
determination. Nothing contained herein shall be deemed to restrict the right of
a Holder  to  exercise  this  Warrant,  or part  thereof,  at such  time as such
exercise will not violate the provisions of this Section 4.

         5. Payment of the Exercise Price. The Holder may pay the Exercise Price
in either of the  following  forms or, at the election of Holder,  a combination
thereof:

         (a) Cash Exercise: by delivery of immediately available funds.
                                      -4-
<PAGE>
         (b)  Cashless  Exercise:  by  surrender  of this Warrant to the Company
together  with a notice of cashless  exercise,  in which event the Company shall
issue to the Holder the number of Warrant Shares determined as follows:

                  X = Y x (A-B)/A

where:            X = the number of Warrant Shares to be issued to the Holder.

                  Y = the number of Warrant  Shares  with  respect to which this
                  Warrant is being exercised.

                  A = the average of the Closing Bid Prices of the Common  Stock
                  for the five (5) Trading  Days  immediately  prior to (but not
                  including) the Exercise Date.

                  B = the Exercise Price.

For purposes of Rule 144 under the  Securities  Act of 1933,  as amended,  it is
intended,  understood  and  acknowledged  that the  Warrant  Shares  issued in a
cashless  exercise  transaction  shall be deemed to have  been  acquired  by the
Holder,  and the holding  period for the Warrant  Shares shall be deemed to have
been  commenced,  on the  Closing  Date (as defined in the  Securities  Purchase
Agreement).

         6. Anti-Dilution Adjustments.

         (a) Stock Dividend. If the Company shall at any time declare a dividend
payable in shares of Common Stock, then the Holder hereof, upon exercise of this
Warrant after the record date for the  determination  of Holders of Common Stock
entitled to receive such dividend,  shall be entitled to receive, in addition to
the number of shares of Common Stock as to which this Warrant is exercised, such
additional  shares of Common Stock as such Holder  would have  received had this
Warrant been  exercised  immediately  prior to such record date and the Exercise
Price will be proportionately adjusted.

         (b) Recapitalization or  Reclassification.  If the Company shall at any
time effect a recapitalization, reclassification or other similar transaction of
such  character  that the shares of Common Stock shall be changed into or become
exchangeable  for a larger or smaller number of shares,  then upon the effective
date thereof, the number of shares of Common Stock which the Holder hereof shall
be entitled to purchase  upon  exercise of this  Warrant  shall be  increased or
decreased,  as the case may be, in direct proportion to the increase or decrease
in the  number of shares  of  Common  Stock by reason of such  recapitalization,
reclassification or similar transaction, and the Exercise Price shall be, in the
case of an increase in the number of shares,  proportionally  decreased  and, in
the case of  decrease  in the number of shares,  proportionally  increased.  The
Company  shall  give the  Warrant  Holder  the same  notice  at the same time it
provides such notice to holders of Common Stock of any transaction  described in
this Section 6(b).
                                      -5-
<PAGE>
         (c)  Distributions.  If the  Company  shall at any time  distribute  to
holders of Common Stock cash,  evidences of indebtedness or other  securities or
assets (other than cash dividends or distributions payable out of earned surplus
or net profits for the current or a preceding  year) then, in any such case, the
Holder of this  Warrant  shall be  entitled to  receive,  upon  exercise of this
Warrant, with respect to each share of Common Stock issuable upon such exercise,
the amount of cash or evidences of  indebtedness  or other  securities or assets
which such Holder would have been  entitled to receive with respect to each such
share of  Common  Stock as a result  of the  happening  of such  event  had this
Warrant been exercised immediately prior to the record date or other date fixing
shareholders to be affected by such event.

         (d)  Notice  of  Consolidation  or  Merger.  In the  event of a merger,
consolidation,   business   combination,   tender  offer,  exchange  of  shares,
recapitalization, reorganization, redemption or other similar event, as a result
of which shares of Common Stock of the Company shall be changed into the same or
a different number of shares of the same or another class or classes of stock or
securities  or other assets of the Company or another  entity or there is a sale
of all or substantially  all the Company's assets (a "Corporate  Change"),  then
this Warrant  shall be  exercisable  into such class and type of  securities  or
other assets as the Holder would have  received  had the Holder  exercised  this
Warrant  immediately prior to such Corporate  Change;  provided,  however,  that
Company may not affect any Corporate Change unless (i) it first shall have given
thirty (30) business  days' notice to the Holder hereof of any Corporate  Change
and  makes a public  announcement  of such  event at the same time that it gives
such notice and (ii) it requires the resulting successor or acquiring entity (if
not the  Corporation)  to assume by written  instrument  the  obligations of the
Corporation  hereunder  and  under the  Securities  Purchase  Agreement  and the
Registration Rights Agreement.

         (e)  Exercise  Price as  Adjusted.  As used in this  Warrant,  the term
"Exercise  Price" shall mean the purchase price per share specified in paragraph
1 of this Warrant,  until the  occurrence of an event stated in subsection  (a),
(b) or (c) of this paragraph 6, and thereafter shall mean said price as adjusted
from time to time in accordance with the provisions of each such subsection.  No
such  adjustment  under this  paragraph 6 shall be made  unless such  adjustment
would  change  the  Exercise  Price  at the  time by two  percent  (2%) or more;
provided,  however,  that all adjustments not so made shall be deferred and made
when the aggregate  thereof would change the Exercise  Price at the time by $.01
or more. No adjustment  made pursuant to any provision of this paragraph 6 shall
have the effect of increasing the total  consideration  payable upon exercise of
this  Warrant in respect of all the Common Stock as to which this Warrant may be
exercised.

         (f) Adjustments:  Additional Shares, Securities or Assets. In the event
that at any time, as a result of an adjustment  made pursuant to this Section 6,
the Holder of this Warrant shall, upon exercise of this Warrant, become entitled
to receive  shares  and/or other  securities or assets (other than Common Stock)
then,  wherever  appropriate,  all  references  herein to shares of Common Stock
shall be deemed to refer to and include such shares  and/or other  securities or
assets;  and  thereafter  the number of such shares  and/or other  securities or
assets  shall be  subject to  adjustment  from time to time in a manner and upon
terms as nearly equivalent as practicable to the provisions of this paragraph 6.
                                      -6-
<PAGE>
         7. Fractional  Interests.  No fractional  shares or scrip  representing
fractional  shares shall be issuable upon the exercise of this  Warrant,  but on
exercise of this Warrant,  the Holder hereof may purchase only a whole number of
shares of Common Stock. If, on exercise of this Warrant, the Holder hereof would
be  entitled  to a  fractional  share of  Common  Stock or a right to  acquire a
fractional share of Common Stock, such fractional share shall be disregarded and
the number of shares of Common Stock  issuable upon exercise shall be rounded up
or down to the nearest whole number of shares of Common Stock.

         8. Transfer of this  Warrant.  The Holder may sell,  transfer,  assign,
pledge or otherwise dispose of this Warrant, in whole or in part, as long as (A)
such sale or other  disposition  is made  pursuant to  pursuant to an  effective
registration  statement or an exemption to the registration  requirements of the
Securities Act of 1933, as amended,  and applicable state laws and (B) such sale
or other disposition is made to an accredited  investor (as such term is defined
in  Regulation  D under  the  Securities  Act).  Upon  such  transfer  or  other
disposition, the Holder shall deliver a written notice to Company, substantially
in the form of the Transfer  Notice  attached hereto as Exhibit B (the "Transfer
Notice"),  indicating  the  person  or  persons  to whom this  Warrant  shall be
transferred and, if less than all of this Warrant is transferred or this Warrant

                          REGISTRATION RIGHTS AGREEMENT

         REGISTRATION RIGHTS AGREEMENT (this  "Agreement"), dated as of July 13,
1998, by and among OrthoLogic Corp., a Delaware corporation (the "Company"), and
each of the entities  whose names appear on the  signature  pages  hereof.  Such
entities are each referred to herein as a "Purchaser" and, collectively,  as the
"Purchasers".

         The Company has agreed,  on the terms and subject to the conditions set
forth  in  the  Securities   Purchase  Agreement  of  even  date  herewith  (the
"Securities  Purchase  Agreement"),  to issue and sell to each Purchaser  shares
(the "Preferred Shares") of the Company's Series B Convertible  Preferred Stock,
par value $0.0005 per share (the  "Preferred  Stock"),  and a Warrant  (each,  a
"Warrant" and, when taken together with all of the warrants  issued  pursuant to
the Securities Purchase Agreement,  the "Warrants") entitling the holder thereof
to purchase  shares (the "Warrant  Shares") of the Company's  Common Stock,  par
value  $0.0005  per  share  (the  "Common  Stock").  The  Preferred  Shares  are
convertible   pursuant  to  the  Company's   Certificate  of  Designation   (the
"Certificate  of  Designation")  into  shares (the  "Conversion  Shares") of the
Common Stock.  In order to induce the  Purchasers  to enter into the  Securities
Purchase  Agreement,  the  Company  has agreed to provide  certain  registration
rights under the Securities Act of 1933, as amended (the "Securities  Act"), and
under applicable state  securities laws.  Capitalized  terms used herein and not
otherwise defined shall have the respective meanings set forth in the Securities
Purchase Agreement.

         In  consideration  of  each  Purchaser  entering  into  the  Securities
Purchase Agreement,  and other good and valuable consideration,  the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows:

         1. DEFINITIONS.
            -----------

         For  purposes of this  Agreement,  the  following  terms shall have the
meanings specified:

                  (a) "Filing Deadline" shall mean September 3, 1998;

                  (b) "Tranche A Closing Date" shall have the meaning  specified
                  in the Securities Purchase Agreement;

                  (c)  "Registration  Deadline" means the seventieth  (70th) day
                  following the Filing Deadline;

                  (d)  "Holder"  means any person  owning or having the right to
                  acquire, through conversion of Preferred Shares or exercise of
                  the Warrant, Registrable Securities,  including initially each
                  Purchaser and thereafter any permitted assignee thereof;

                  (e) "Register",  "registered"  and  "registration"  refer to a
                  registration  effected by preparing and filing a  registration
                  statement or statements in compliance  with the Securities Act
                  and pursuant to Rule 415 under the Securities Act ("Rule 415")
                  or any
<PAGE>
                  successor  rule  providing for the offering of securities on a
                  continuous or delayed basis  ("Registration  Statement"),  and
                  the   declaration   or  ordering  of   effectiveness   of  the
                  Registration   Statement  by  the   Securities   and  Exchange
                  Commission (the "Commission"); and

                  (f) "Registrable  Securities"  means the Conversion Shares and
                  the  Warrant  Shares  and any other  shares  of  Common  Stock
                  issuable  pursuant to the terms of the Preferred  Stock or the
                  Warrants, whether as a dividend, payment of a redemption price
                  or  otherwise,  and any  shares  of  capital  stock  issued or
                  issuable  from  time  to  time  (with  any   adjustments)   in
                  replacement of, in exchange for or otherwise in respect of the
                  Conversion  Shares or the Warrant  Shares,  including  without
                  limitation any  securities  received by a Holder in connection
                  with an Exchange Transaction (as defined in the Certificate of
                  Designation).

         2. MANDATORY REGISTRATION.
            ----------------------

                  (a) On or  before  the  Filing  Deadline,  the  Company  shall
prepare and file with the Commission a  Registration  Statement on Form S-3 as a
"shelf"  registration  statement  under Rule 415 covering the resale of at least
200% of the  number  of  shares  of  Registrable  Securities  then  issuable  on
conversion of the Preferred Shares and exercise of the Warrants then outstanding
(such number to be determined  using the  Conversion  Price or exercise price in
effect on the date of such filing and without  regard to any  restriction on the
ability of a Holder to convert  Preferred  Shares or exercise the Warrants as of
such date). The  Registration  Statement shall state, to the extent permitted by
Rule 416 under the Securities Act, that it also covers such indeterminate number
of shares of Common  Stock as may be  required to effect (i)  conversion  of the
Preferred  Shares  to  prevent  dilution  resulting  from  stock  splits,  stock
dividends or similar events,  or by reason of changes in the Conversion Price in
accordance with the terms of the Certificate of Designation and (ii) exercise of
the Warrants in full to prevent  dilution  resulting  from stock  splits,  stock
dividends or similar events. The number of shares initially registered under the
Registration Statement shall be allocated pro rata among the Purchasers based on
the  number of  Preferred  Shares  issued  to each  Purchaser  at the  Tranche A
Closing. Each increase in the number of shares registered under the Registration
Statement  shall be allocated  pro rata among the Holders based on the number of
Preferred Shares held by such Holder at the time of such increase.  In the event
that a Holder shall sell or otherwise  transfer any of such  Holder's  Preferred
Shares,  each  transferee  shall  be  allocated  a  pro  rata  portion  of  such
transferor's  allocation of  registered  shares.  Any portion of such  allocated
amount which  remains  allocated to any person or entity which does not hold any
Preferred  Shares shall be allocated to the remaining  Holders pro rata based on
the number of Preferred Shares then held by such Holders.

                  (b) The  Company  shall  use its best  efforts  to  cause  the
Registration  Statement to become effective as soon as practicable following the
filing thereof, but in no event later than the Registration  Deadline, and shall
submit to the  Commission,  within one (1) business day after the Company learns
that no review of the  Registration  Statement  will be made by the staff of the
Commission or that the staff of the  Commission  has no further  comments on the
Registration  Statement,  as the case may be, a request for  acceleration of the
effectiveness of the Registration
                                      -2-
<PAGE>
Statement  to a time and date not later than  forty-eight  (48) hours  after the
submission of such request,  and maintain the  effectiveness of the Registration
Statement  until  the  earlier  to occur  of (i) the  date on  which  all of the
Registrable Securities have been sold pursuant to the Registration Statement and
(ii) the date on  which  all of the  remaining  Registrable  Securities  (in the
reasonable  opinion of counsel to the Purchaser) may be immediately  sold to the
public under Rule 144(k) or any successor provision (the "Registration Period").

                  (c) If (A)  the  Registration  Statement  is not  filed  on or
before the Filing Deadline or declared  effective by the Commission on or before
the  Registration  Deadline  or (B) after the  Registration  Statement  has been
declared effective by the Commission,  sales of Registrable Securities cannot be
made by a Holder under the Registration  Statement for any reason not within the
exclusive control of such Holder (other than such Registrable  Securities as are
then freely saleable pursuant to Rule 144(k) under the Securities Act), (each, a
"Registration  Event"),  the Company shall pay to each Holder an amount equal to
the lesser of (x) one and one half percent  (1.5%) per month and (y) the highest
rate permitted by applicable  law, times the aggregate  Stated Value (as defined
in the Certificate of Designation) of the Preferred  Shares held by such Holder,
accruing  daily and  compounded  monthly,  from the date on which a Registration
Event first occurs until the date on which the  Registration  Event is no longer
continuing.  The amounts  paid or payable by the Company  hereunder  shall be in
addition  to any  other  remedies  available  to a Holder at law or in equity or
pursuant  to the  terms of any  other  Transaction  Document.  Payments  of cash
pursuant  hereto shall be made within five (5) days after the end of each period
that gives rise to such  obligation,  provided  that, if any such period extends
for  more  than  thirty  (30)  days,  payments  shall be made at the end of each
thirty-day period.

                  (d) In the event that (A) the  Registration  Statement  is not
declared   effective  by  the  twentieth   (20th)  Business  Day  following  the
Registration  Deadline,  (B) after the Registration  Statement has been declared
effective by the Commission, sales of Registrable Securities cannot be made by a
Holder under the Registration  Statement for any reason not within the exclusive
control of such  Holder  (other  than such  Registrable  Securities  as are then
freely  saleable  pursuant to Rule 144(k) under the Securities  Act), or (C) the
Common Stock is not included for  quotation on the Nasdaq Stock Market or listed
on the New York Stock  Exchange  or the  American  Stock  Exchange,  (each event
described  in  clause  (A),  (B)  or  (C)  being  hereinafter  referred  to as a
"Repricing  Event"), in addition to the amounts which may be payable pursuant to
paragraph 2(c) above,  the Fixed Conversion Price (as defined in the Certificate
of  Designation)  for any conversion of Preferred  Shares  occurring  during the
twenty two (22) Trading  Days  following  the Cure Date (as defined  below) with
respect  to such  event  shall be  deemed  to be equal to the  lesser of (i) the
lowest Conversion Price (as defined in the Certificate of Designation) in effect
during the period  between  the date on which a Repricing  Event  occurs and the
date on which such Repricing Event is no longer continuing (the "Cure Date") and
(ii) the  Fixed  Conversion  Price  that  would  otherwise  be in  effect on the
relevant Conversion Date (as defined in the Certificate of Designation).

         3. PIGGYBACK REGISTRATION.
            ----------------------

                  If at any time  prior to the  expiration  of the  Registration
Period,  (i) the Company  proposes to register  shares of Common Stock under the
Securities Act in connection with the public
                                      -3-
<PAGE>
offering of such shares for cash (other than a registration  relating  solely to
the sale of securities to participants in a Company stock plan or employee stock
award or a registration on Form S-4 under the Securities Act or any successor or
similar form  registering  stock  issuable upon a  reclassification,  a business
combination  involving  an  exchange  of  securities  or an  exchange  offer for
securities of the issuer or another entity) (a "Proposed Registration") and (ii)
a registration  statement covering the sale of all of the Registrable Securities
is not then  effective  and  available  for sales  thereof by the  Holders,  the
Company  shall,  at such time,  promptly give each Holder written notice of such
Proposed Registration.  Each Holder shall have thirty (30) days from its receipt
of such notice to deliver to the Company a written request specifying the amount
of  Registrable  Securities  that such Holder  intends to sell and such Holder's
intended method of distribution. Upon receipt of such request, the Company shall
use its best efforts to cause all Registrable  Securities  which the Company has
been  requested to register to be  registered  under the  Securities  Act to the
extent  necessary to permit their sale or other  disposition in accordance  with
the intended  methods of  distribution  specified in the request of such Holder;
provided, however, that the Company shall have the right to postpone or withdraw
any registration effected pursuant to this paragraph 3 without obligation to the
Holder. If, in connection with any underwritten  public offering for the account
of the Company, the managing underwriter(s) thereof shall impose a limitation on
the number of shares of Common  Stock which may be included in the  Registration
Statement because, in such underwriter(s)' judgment,  marketing or other factors
dictate such limitation is necessary to facilitate  public  distributions,  then
the Company shall be obligated to include in such  Registration  Statement  only
such limited  portion of the  Registrable  Securities with respect to which each
Holder has requested inclusion  hereunder as such  underwriter(s)  shall permit.
Any exclusion of Registrable Securities shall be made pro rata among the Holders
seeking to include  Registrable  Securities in the  Registration  Statement,  in
proportion to the number of Registrable Securities sought to be included by such
Holders;  provided,  however, that the Company shall not exclude any Registrable
Securities unless the Company has first excluded all outstanding securities, the
holders  of which are not  entitled  to  inclusion  of such  securities  in such
Registration  Statement  or are not  entitled  to pro  rata  inclusion  with the
Registrable  Securities;  and provided,  further,  however,  that,  after giving
effect to the  immediately  preceding  proviso,  any  exclusion  of  Registrable
Securities  shall be made pro rata with holders of other  securities  having the
right to include such securities in the Registration Statement before any Holder
includes any or all of its Registrable  Securities in any registration statement
relating to an  underwritten  public offering with respect to which, in the good
faith opinion of the managing underwriter,  the inclusion in the offering of all
shares  requested to be registered by all persons  holding  registration  rights
would  materially  jeopardize the  successful  marketing of the securities to be
sold.

         4. OBLIGATIONS OF THE COMPANY.
            --------------------------

         In addition to performing its  obligations  hereunder,  including those
pursuant to paragraphs 2(a) and 2(b) above, the Company shall:

                  (a) prepare and file with the Commission  such  amendments and
supplements to the Registration  Statement and the prospectus used in connection
with  the  Registration  Statement  as may  be  necessary  to  comply  with  the
provisions  of  the  Securities  Act or to  maintain  the  effectiveness  of the
Registration  Statement during the Registration  Period, or as may be reasonably
requested by a Holder
                                      -4-
<PAGE>
in order to  incorporate  information  concerning  such Holder or such  Holder's
intended method of distribution;

                  (b) in the event that the number of shares available under the
Registration Statement filed by the Company hereunder is insufficient during any
period  of  three  consecutive  trading  days to cover  175% of the  Registrable
Securities  then  issued or issuable  (such  number to be  determined  using the
Conversion Price or exercise price in effect on such dates and without regard to
any  restriction  on the  ability  of a Holder to  convert  Preferred  Shares or
exercise the Warrants as of such dates),  the Company shall  promptly  amend the
Registration  Statement, or file a new Registration Statement, or both, so as to
cover 200% of such Registrable Securities,  in any event as soon as practicable,
but not later than the tenth  business day  following the last day of such three
day period. Any Registration  Statement filed pursuant to this paragraph 4 shall
state that, to the extent  permitted by Rule 416 under the Securities  Act, such
Registration  Statement  also covers  such  indeterminate  number of  additional
shares of Common Stock as may become  issuable upon  conversion of the Preferred
Shares or exercise of the Warrants in full.  Unless and until such  amendment or
new Registration Statement becomes effective,  each Holder shall have the rights
described in Section 2 above;

                  (c) secure the  designation  and quotation of the  Registrable
Securities  on the Nasdaq  Stock  Market or the listing  thereof on the New York
Stock Exchange or the American Stock Exchange;

                  (d)  furnish  to each  Holder  such  number  of  copies of the
prospectus  included in such  Registration  Statement,  including a  preliminary
prospectus,  in conformity with the requirements of the Securities Act, and such
other documents as such Holder may reasonably request in order to facilitate the
disposition of such Holder's Registrable Securities;

                  (e) use all  commercially  reasonable  efforts to  register or
qualify the  Registrable  Securities  under the securities or "blue sky" laws of
such  jurisdictions  within the United States as shall be  reasonably  requested
from time to time by a Holder, and do any and all other acts or things which may
be necessary or advisable to enable such Holder to consummate the public sale or
other disposition of the Registrable Securities in such jurisdictions;  provided
that the Company shall not be required in connection therewith or as a condition
thereto  to qualify to do  business  or to file a general  consent to service of
process in any such jurisdiction;

                  (f) in the event of an  underwritten  public  offering  of the
Registrable  Securities,  enter  into  and  perform  its  obligations  under  an
underwriting agreement, in usual and customary form reasonably acceptable to the
Company, with the managing underwriter of such offering;

                  (g) notify each Holder  immediately upon the occurrence of any
event  as a  result  of  which  the  prospectus  included  in such  Registration
Statement,  as then in effect,  contains an untrue statement of material fact or
omits to state a material  fact  required to be stated  therein or  necessary to
make the statements  therein not misleading in light of the  circumstances  then
existing,  and as promptly  as  practicable,  prepare,  file and furnish to each
Holder a  reasonable  number of copies of a  supplement  or an amendment to such
prospectus  as may be  necessary  so that such  prospectus  does not  contain an
untrue  statement of material  fact or omit to state a material fact required to
be stated therein or 
                                      -5-
<PAGE>
necessary  to make  the  statements  therein  not  misleading  in  light  of the
circumstances then existing;

                  (h) use all  commercially  reasonable  efforts to prevent  the
issuance of any stop order or other order  suspending the  effectiveness of such
Registration Statement and, if such an order is issued, to obtain the withdrawal
thereof at the earliest  possible time and to notify each Holder of the issuance
of such order and the resolution thereof;

                  (i) furnish to each Holder, on the date that such Registration
Statement becomes effective,  (x) a letter,  dated such date, of outside counsel
representing the Company (and reasonably acceptable to such Holder) addressed to
such Holder,  confirming the effectiveness of the Registration Statement and, to
the  knowledge of such  counsel,  the absence of any stop order,  and (y) in the
case of an  underwriting,  (A) an  opinion,  dated  such date,  of such  outside
counsel,  in form and substance as is customarily  given to  underwriters  in an
underwritten  public  offering,  and (B) a letter,  dated  such  date,  from the
Company's independent certified public accountants,  in form and substance as is
customarily given by independent certified public accountants to underwriters in
an  underwritten  public  offering,  addressed to the  underwriters  and to each
Holder;

                  (j)   provide   each  Holder  and  its   representatives   the
opportunity to conduct a reasonable inquiry of the Company's financial and other
records during normal business hours and make available its officers,  directors
and  employees  for  questions  regarding  information  which  such  Holder  may
reasonably request in order to fulfill any due diligence obligation on its part;
and

                  (k) permit counsel for each Holder (at such Holder's  expense)
to review such Registration Statement and all amendments and supplements thereto
a reasonable period of time prior to the filing thereof with the Commission.

         5. OBLIGATIONS OF EACH HOLDER.
            --------------------------

         In  connection  with the  registration  of the  Registrable  Securities
pursuant to the Registration Statement, each Holder shall:

                  (a) furnish to the Company such  information  regarding itself
and the intended method of disposition of Registrable  Securities as the Company
shall reasonably request in order to effect the registration thereof;

                  (b)  upon  receipt  of any  notice  from  the  Company  of the
happening  of any  event  of the  kind  described  in  paragraphs  4(g) or 4(h),
immediately  discontinue  disposition of Registrable  Securities pursuant to the
Registration  Statement  until  the  filing of an  amendment  or  supplement  as
described  in  paragraph  4(g) or  withdrawal  of the stop order  referred to in
paragraph 4(h);

                  (c)  in  the  event  of  an   underwritten   offering  of  the
Registrable Securities in which such Holder participates, enter into a customary
and reasonable  underwriting  agreement and execute such other  documents as the
managing underwriter for such offering may reasonably request;
                                      -6-
<PAGE>
                  (d) to the  extent  required  by  applicable  law,  deliver  a
prospectus to each purchaser of Registrable Securities; and

                  (e) notify the Company when it has sold all of the Registrable
Securities theretofore held by it.

         6. INDEMNIFICATION.
            ---------------

         In  the  event  that  any  Registrable  Securities  are  included  in a
Registration Statement under this Agreement:

                  (a)  To  the  extent  permitted  by  law,  the  Company  shall
indemnify  and hold harmless each Holder,  the officers,  directors,  employees,
agents and representatives of such Holder, and each person, if any, who controls
such Holder within the meaning of the Securities Act or the Securities  Exchange
Act of 1934, as amended (the "1934 Act"), against any losses,  claims,  damages,
liabilities  or reasonable  out-of-pocket  expenses  (whether  joint or several)
(collectively,   including  legal  or  other  expenses  reasonably  incurred  in
connection with investigating or defending same, "Losses"),  insofar as any such
Losses arise out of or are based upon (i) any untrue statement or alleged untrue
statement of a material fact contained in such Registration Statement, including
any  preliminary  prospectus  or  final  prospectus  contained  therein  or  any
amendments or supplements  thereto,  or (ii) the omission or alleged omission to
state  therein a material fact  required to be stated  therein,  or necessary to
make the statements therein, in light of the circumstances under which they were
made, not  misleading.  The Company will  reimburse  such Holder,  and each such
officer, director, employee, agent, representative or controlling person for any
legal or other  expenses as reasonably  incurred by any such entity or person in
connection with investigating or defending any Loss; provided, however, that the
foregoing indemnity shall not apply to amounts paid in settlement of any Loss if
such  settlement is effected  without the consent of the Company  (which consent
shall not be  unreasonably  withheld),  nor shall the  Company be  obligated  to
indemnify  any person for any Loss to the extent that such Loss arises out of or
is based upon and in  conformity  with  written  information  furnished  by such
person expressly for use in such Registration Statement; and provided,  further,
that the Company  shall not be required  to  indemnify  any person to the extent
that any Loss results from such person selling  Registrable  Securities (i) to a
person  to whom  there  was not  sent  or  given,  at or  prior  to the  written
confirmation  of the  sale of such  shares,  a copy of the  prospectus,  as most
recently  amended or  supplemented,  if the Company has previously  furnished or
made available copies thereof or (ii) during any period following written notice
by the Company to such Holder of an event described in paragraph 4(g) or 4(h).

                  (b) To the  extent  permitted  by  law,  each  Holder,  acting
severally and not jointly,  shall  indemnify and hold harmless the Company,  the
officers,  directors,  employees, agents and representatives of the Company, and
each  person,  if any,  who  controls  the  Company  within  the  meaning of the
Securities  Act or the 1934 Act,  against  any Losses to the extent (and only to
the  extent)  that  any  such  Losses  arise  out of or are  based  upon  and in
conformity with written  information  furnished by such Holder expressly for use
in such  Registration  Statement;  and such Holder will  reimburse  any legal or
other  expenses as  reasonably  incurred  by the  Company and any such  officer,
director, employee, agent, representative,  or controlling person, in connection
with investigating or 
                                      -7-
<PAGE>
defending any such Loss; provided,  however,  that the foregoing indemnity shall
not apply to amounts paid in settlement  of any such Loss if such  settlement is
effected  without  the  consent  of such  Holder,  which  consent  shall  not be
unreasonably  withheld;  provided,  that, in no event shall any indemnity  under
this  subparagraph 6(b) exceed the net purchase price of securities sold by such
Holder under the Registration Statement.

                  (c) Promptly after receipt by an indemnified  party under this
paragraph  6 of  notice  of  the  commencement  of  any  action  (including  any
governmental action), such indemnified party will, if a claim in respect thereof
is to be made  against any  indemnifying  party under this Section 6, deliver to
the  indemnifying  party a written  notice of the  commencement  thereof and the
indemnifying  party  shall  have the right to  participate  in and to assume the
defense thereof with counsel  mutually  satisfactory  to the parties;  provided,
however,  that an  indemnified  party  shall  have the right to  retain  its own
counsel,  with the reasonably  incurred fees and expenses of one such counsel to
be paid by the indemnifying  party, if  representation of such indemnified party
by the counsel retained by the indemnifying  party would be inappropriate  under
applicable  standards  of  professional  conduct  due  to  actual  or  potential
conflicting  interests  between  such  indemnified  party  and any  other  party
represented by such counsel in such  proceeding.  The failure to deliver written
notice to the indemnifying party within a reasonable time of the commencement of
any such action, to the extent prejudicial to its ability to defend such action,
shall relieve such indemnifying  party of any liability to the indemnified party
under this  paragraph  6 with  respect to such  action,  but the  omission so to
deliver  written  notice to the  indemnifying  party will not  relieve it of any
liability that it may have to any  indemnified  party  otherwise than under this
paragraph 6 or with respect to any other action.

                  (d) In the event that the indemnity  provided in paragraph (a)
or (b) of this Section 6 is  unavailable  or  insufficient  to hold  harmless an
indemnified party for any reason,  the Company and each Holder agree,  severally
and not jointly,  to contribute to the aggregate  Losses to which the Company or
such Holder may be subject in such  proportion as is  appropriate to reflect the
relative fault of the Company and such Holder in connection  with the statements
or omissions which resulted in such Losses;  provided,  however, that in no case
shall such Holder be  responsible  for any amount in excess of the net  purchase
price of securities sold by it under the Registration Statement.  Relative fault
shall be  determined  by  reference to whether any alleged  untrue  statement or
omission relates to information  provided by the Company or by such Holder.  The
Company  and each  Holder  agree  that it would  not be just  and  equitable  if
contribution  were  determined  by pro rata  allocation  or any other  method of
allocation which does not take account of the equitable  considerations referred
to above. Notwithstanding the provisions of this paragraph (d), no person guilty
of  fraudulent  misrepresentation  (within the  meaning of Section  11(f) of the
Securities  Act) shall be  entitled to  contribution  from any person who is not
guilty of such  fraudulent  misrepresentation.  For  purposes of this Section 6,
each person who  controls a Holder  within the meaning of either the  Securities
Act or  the  Exchange  Act  and  each  officer,  director,  employee,  agent  or
representative of such Holder shall have the same rights to contribution as such
Holder,  and each person who controls  the Company  within the meaning of either
the  Securities  Act or the Exchange Act and each officer,  director,  employee,
agent  or   representative  of  the  Company  shall  have  the  same  rights  to
contribution  as the Company,  subject in each case to the applicable  terms and
conditions of this subparagraph (d).
                                      -8-
<PAGE>
                  (e) The  obligations of the Company and each Holder under this
paragraph 6 shall survive the conversion or redemption, if any, of the Preferred
Shares,  the  exercise  of  the  Warrant,  the  completion  of any  offering  of
Registrable   Securities  pursuant  to  a  Registration   Statement  under  this
Agreement, or otherwise.

         7. REPORTS.
            -------

                  With a view to making available to each Holder the benefits of
Rule 144 under the  Securities  Act ("Rule  144") and any other  similar rule or
regulation  of the  Commission  that may at any time  permit such Holder to sell
securities of the Company to the public without registration, the Company agrees
to:

                  (a) make and keep public information available, as those terms
are understood and defined in Rule 144;

                  (b) file with the  Commission  in a timely  manner all reports
and other  documents  required of the Company under the  Securities  Act and the
1934 Act; and

                  (c)  furnish to such  Holder,  so long as such Holder owns any
Registrable  Securities,  forthwith upon request (i) a written  statement by the
Company,  if true, that it has complied with the reporting  requirements of Rule
144, the  Securities Act and the 1934 Act, (ii) a copy of the most recent annual
or quarterly report of the Company and such other reports and documents so filed
by the Company,  and (iii) such other information as may be reasonably requested
in  availing  such  Holder of any rule or  regulation  of the  Commission  which
permits the selling of any such securities without registration.

         8. MISCELLANEOUS.
            -------------

                  (a)  Expenses  of  Registration.   All  expenses,  other  than
underwriting  discounts and commissions and fees and expenses of counsel to each
Holder, incurred in connection with the registrations, filings or qualifications
described herein,  including (without  limitation) all registration,  filing and
qualification fees, printers' and accounting fees, the fees and disbursements of
counsel for the Company,  and the fees and disbursements  incurred in connection
with the opinion and letter  described in paragraph 4(i) hereof,  shall be borne
by the Company.

                  (b) Amendment;  Waiver. Any provision of this Agreement may be
amended  only  pursuant  to a written  instrument  executed  by the  Company and
Holders of at least two thirds (2/3) of the outstanding  Registrable  Securities
or, if no Registrable  Securities are outstanding,  of at least two thirds (2/3)
of the  outstanding  Preferred  Shares.  Any  waiver of the  provisions  of this
Agreement  may be made only  pursuant  to a written  instrument  executed by the
party against whom  enforcement is sought.  Any amendment or waiver  effected in
accordance  with this paragraph  shall be binding upon each Holder,  each future
Holder,  and the  Company.  The  failure of any party to  exercise  any right or
remedy  under  this  Agreement  or  otherwise,  or the  delay  by any  party  in
exercising such right or remedy, shall not operate as a waiver thereof.

                          SECURITIES PURCHASE AGREEMENT


         SECURITIES PURCHASE AGREEMENT (this  "Agreement"), dated as of July 13,
1998, by and between  OrthoLogic Corp., a Delaware  corporation (the "Company"),
and each of the entities whose names appear on the signature pages hereof.  Such
entities are each referred to herein as a "Purchaser" and, collectively,  as the
"Purchasers".

         The Company wishes to sell to each Purchaser, and each Purchaser wishes
to  purchase,  on the  terms and  subject  to the  conditions  set forth in this
Agreement, shares (the "Preferred Shares") of the Company's Series B Convertible
Preferred Stock, par value $0.0005 per share (the "Preferred Stock") and related
Warrants  in the  form  attached  hereto  as  Exhibit  A (the  "Warrants").  The
Preferred  Shares are  convertible  pursuant  to the terms of a  Certificate  of
Designation  relating  to the  Preferred  Stock,  the form of which is  attached
hereto  as  Exhibit  B (the  "Certificate  of  Designation")  into  shares  (the
"Conversion  Shares") of the Company's common stock, par value $0.0005 per share
(the "Common  Stock").  The Warrants are exercisable into shares of Common Stock
(the "Warrant Shares") in accordance with their terms. The Preferred Shares, the
Conversion Shares, the Warrants and the Warrant Shares are collectively referred
to herein as the "Securities".

         The Company  has agreed to effect the  registration  of the  Conversion
Shares and the Warrant  Shares under the Securities Act of 1933, as amended (the
"Securities  Act"),  pursuant to a  Registration  Rights  Agreement of even date
herewith by and among the Company and the Purchasers (the  "Registration  Rights
Agreement"). The sale of the Preferred Shares and the Warrants by the Company to
the Purchasers  will be effected in reliance upon the exemption from  securities
registration  afforded by the  provisions of Regulation D  ("Regulation  D"), as
promulgated by the Securities and Exchange  Commission (the "Commission")  under
the Securities Act.

         The Company and each Purchaser hereby agree as follows:

1. PURCHASE AND SALE OF PREFERRED SHARES.
   -------------------------------------

         1.1  Agreement to Purchase and Sell.  Upon the terms and subject to the
satisfaction or waiver of the conditions set forth herein, the Company agrees to
sell and each  Purchaser  severally  agrees to purchase  the number of Preferred
Shares, together with Warrants to purchase the number of shares of Common Stock,
set  forth  below  such  Purchaser's  name on the  signature  pages  hereof at a
purchase  price for such  Preferred  Shares and  Warrants  equal to one thousand
dollars  ($1,000)  times  the  number  of  Preferred  Shares  purchased  by such
Purchaser  (the "Purchase  Price").  The Warrants will entitle each Purchaser to
purchase forty (40) shares of Common Stock for each Preferred Share purchased by
such Purchaser.  The Preferred Shares and Warrants will be sold,  subject to the
conditions set forth herein, in two (2) tranches (each a "Tranche" and together,
the "Tranches").
<PAGE>
         1.2 Closing of Tranche A. The closing of the initial Tranche  hereunder
("Tranche A"), at which closing the Purchasers  will purchase  Preferred  Shares
and  Warrants  for an  aggregate  Purchase  Price  of  fifteen  million  dollars
($15,000,000),  will occur upon the  satisfaction  (or  waiver) of the Tranche A
Closing  Conditions  (as defined  below) (the "Tranche A Closing").  The date on
which the Tranche A Closing occurs is hereinafter  referred to as the "Tranche A
Closing Date". Subject to the satisfaction or waiver of the conditions set forth
herein,  the Tranche A Closing will be deemed to occur when this  Agreement  and
the other  Transaction  Documents  (as  defined  below) have been  executed  and
delivered by the Company and each Purchaser  (which  delivery may be effected by
facsimile transmission), and full payment of the Purchase Price has been made by
each Purchaser by wire transfer of immediately  available funds against physical
delivery by the Company of duly executed certificates representing the Preferred
Shares and the Warrants purchased by such Purchaser at the Tranche A Closing.

         1.3 Closing of Tranche B. If,  during the period of three hundred (300)
days following the Tranche A Closing Date (the "Initial Tranche B Period"),  the
Closing Bid Price (as defined in the Certificate of Designation)  for the Common
Stock is at or above eight  dollars  ($8.00) per share for ten (10)  consecutive
Trading Days (as defined in the  Certificate of  Designation),  the Company must
sell to each  Purchaser  its  proportionate  share of the  tranche of  Preferred
Shares and  Warrants  ("Tranche  B") to be issued at the  Tranche B Closing  (as
defined below) for an aggregate  Purchase Price to all of the Purchasers of five
million dollars  ($5,000,000) at a subsequent closing (the "Tranche B Closing"),
such  proportionate  share to be  calculated  based on the  number of  Preferred
Shares  purchased  by such  Purchaser  at the Tranche A Closing  relative to the
aggregate  number of Preferred  Shares purchased by all of the Purchasers at the
Tranche A Closing.  In such event, the Tranche B Closing will occur,  subject to
the  satisfaction  (or waiver) of the Tranche B Closing  Conditions  (as defined
below), on the fifth (5th) business day (or other date mutually agreeable by the
Company and the holders of a majority of the Preferred Shares then  outstanding)
following  the tenth such Trading Day. If, at any time  following the end of the
Initial Tranche B Period,  but prior to the second  anniversary of the Tranche A
Closing  Date (the  "Tranche B Option  Period"),  the  Tranche B Closing has not
occurred,  and  the  Closing  Bid  Price  (as  defined  in  the  Certificate  of
Designation) for the Common Stock is at or above eight dollars ($8.00) per share
for ten  (10)  consecutive  Trading  Days  (as  defined  in the  Certificate  of
Designation)(a  "Tranche B Option  Event"),  then the Company may, at its option
and subject to the satisfaction (or waiver) of the Tranche B Closing  Conditions
(the  "Tranche B Option"),  sell to each  Purchaser,  and such  Purchaser  shall
purchase,  its  proportionate  share of the Preferred  Shares and Warrants to be
issued at the Tranche B Closing for an  aggregate  Purchase  Price to all of the
Purchasers of up to five million dollars ($5,000,000),  such proportionate share
to be  calculated  based on the number of  Preferred  Shares  purchased  by such
Purchaser at the Tranche A Closing relative to the aggregate number of Preferred
Shares  purchased by all of the  Purchasers at the Tranche A Closing;  provided,
however,  that in order for the  Company to exercise  the Tranche B Option,  the
Company must deliver a written  notice  thereof to each Purchaser on a date that
is (i) not more than  thirty  (30) days  following  the  first  occurrence  of a
Tranche B Option Event during the Tranche B Option Period and (ii) at least five
(5) days prior to the date on which the  Tranche B Closing  is to occur,  and in
such notice specify the number of Preferred Shares and Warrants that the Company
proposes  to issue and the date on which the  Tranche B Closing is to occur,  it
being  understood  (A) that the Company may  exercise  the Tranche B Option only
with  
                                      -2-
<PAGE>
respect to the first occurrence of a Tranche B Option Event during the Tranche B
Option  Period,  and (B) that in no event may the Tranche B Closing  occur after
the second  anniversary  of the  Tranche A Closing  Date.  The date on which the
Tranche B Closing  occurs is  hereinafter  referred to as the "Tranche B Closing
Date".  The Tranche B Closing  will be deemed to occur when full  payment of the
Purchase  Price for the  Preferred  Shares and Warrants to be issued and sold at
such  Closing has been made by each  Purchaser by wire  transfer of  immediately
available  funds  against  physical  delivery  by the  Company of duly  executed
certificates  representing the Preferred  Shares and Warrants  purchased by such
Purchaser  at the Tranche B Closing.  The closing of Tranche A or B hereunder is
sometimes  referred  to  as  a  "Closing"  and,  when  taken  together,  as  the
"Closings".

         1.4 Certain  Definitions.  When used herein,  (A) "business  day" shall
mean any day on which the New York Stock  Exchange and  commercial  banks in the
city of New York are open for business, (B) an "affiliate" of a party shall mean
any person or entity  controlling,  controlled  by or under common  control with
that party and (C) "control" shall mean, with respect to an entity,  the ability
to direct the business, operations or management of such entity, whether through
an equity interest therein or otherwise.  The term "Material  Adverse Event", as
such term is used in paragraph  4(a) of the  Certificate of  Designation,  shall
have the meaning set forth on Schedule 1.4 hereof.

2. REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS.
   ------------------------------------------------

         Each  Purchaser   hereby  makes  the  following   representations   and
warranties  to the Company and agrees with the Company  that,  as of the date of
this Agreement and as of the date of each Closing:

         2.1 Authorization;  Enforceability.  Such Purchaser is duly and validly
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
jurisdiction of its  incorporation or organization with full power and authority
to purchase  the  Preferred  Shares and Warrants and to execute and deliver this
Agreement. This Agreement constitutes such Purchaser's valid and legally binding
obligation, enforceable in accordance with its terms, except as such enforcement
may be limited by (i) applicable bankruptcy, insolvency, reorganization or other
laws  of  general  application  relating  to or  affecting  the  enforcement  of
creditors' rights generally and (ii) general principles of equity.

         2.2 Accredited  Investor.  Such Purchaser is an accredited  investor as
that term is defined in Rule 501 of Regulation D, and is acquiring the Preferred
Shares and  Warrants  solely for its own account as a  principal  and not with a
present view to the public  resale or  distribution  of all or any part thereof,
except pursuant to sales that are exempt from the  registration  requirements of
the Securities Act and/or sales registered  under the Securities Act;  provided,
however that in making such  representation,  such  Purchaser  does not agree to
hold the  Securities  for any minimum or specific term and reserves the right to
sell,  transfer or otherwise dispose of the Securities at any time in accordance
with the provisions of this Agreement and with Federal and state securities laws
applicable to such sale, transfer or disposition.

         2.3   Information.   The  Company  has  provided  such  Purchaser  with
information  regarding the business,  operations and financial  condition of the
Company,  and has granted to such Purchaser the  opportunity to ask questions of
and receive answers from representatives of the Company, its officers,
                                      -3-
<PAGE>
directors, employees and agents concerning the Company and materials relating to
the terms and  conditions of the purchase and sale of the  Preferred  Shares and
Warrants  hereunder.  Neither  such  information  nor  any  other  investigation
conducted by such Purchaser or any of its representatives shall modify, amend or
otherwise affect such Purchaser's right to rely on the Company's representations
and warranties contained in this Agreement.

         2.4  Limitations  on  Disposition.  Such Purchaser  acknowledges  that,
except as provided in the Registration Rights Agreement, the Securities have not
been  and are not  being  registered  under  the  Securities  Act and may not be
transferred  or resold without  registration  under the Securities Act or unless
pursuant to an exemption therefrom.

         2.5  Legend.   Such  Purchaser   understands   that  the   certificates
representing  the  Securities  may bear at  issuance  a  restrictive  legend  in
substantially the following form:

                  "The securities  represented by this certificate have not been
                  registered  under the  Securities Act of 1933, as amended (the
                  "Securities  Act"), or the securities  laws of any state,  and
                  may not be offered  or sold  unless a  registration  statement
                  under the Securities Act and applicable  state securities laws
                  shall  have  become  effective  with  regard  thereto,  or  an
                  exemption  from  registration  under  the  Securities  Act and
                  applicable  state  securities  laws is available in connection
                  with such offer or sale. Such securities are issued subject to
                  the provisions of (i) the Certificate of Designation  relating
                  to the  Series B  Convertible  Preferred  Stock of  OrthoLogic
                  Corp. (the "Company"),  (ii) a Securities  Purchase Agreement,
                  dated as of July 9,  1998,  by and among the  Company  and the
                  Purchasers  named  therein,  and (iii) a  Registration  Rights
                  Agreement,  dated as of July 9, 1998, by and among the Company
                  and such Purchasers."

                  Notwithstanding  the foregoing,  it is agreed that, as long as
(A) the resale or transfer (including without limitation a pledge) of any of the
Securities is registered pursuant to an effective  registration  statement,  (B)
such  Securities have been sold pursuant to Rule 144 under the Securities Act or
any successor  provision  ("Rule 144") or (C) such  Securities  are eligible for
resale under Rule 144(k) or any successor  provision,  such Securities  shall be
issued  without any legend or other  restrictive  language  and, with respect to
Securities  upon which such  legend is  stamped,  the  Company  shall  issue new
certificates without such legend to the holder upon request.

3.  REPRESENTATIONS  AND  WARRANTIES OF THE COMPANY. 
    -----------------------------------------------

         The Company hereby makes the following  representations  and warranties
to each  Purchaser and agrees with each  Purchaser  that, as of the date of this
Agreement and as of the date of each Closing: 
                                      -4-
<PAGE>
         3.1 Organization, Good Standing and Qualification.  Each of the Company
and its  subsidiaries is duly organized,  validly  existing and in good standing
under the laws of the jurisdiction of its  incorporation or organization and has
all  requisite  power and  authority to carry on its business as now  conducted.
Each of the Company and its subsidiaries is duly qualified to transact  business
and is in good standing in each  jurisdiction in which the failure so to qualify
would have a material adverse effect on the consolidated  business,  operations,
properties,  financial  condition,  prospects  or results of  operations  of the
Company and its  subsidiaries  taken as a whole or on the ability of the Company
to perform its obligations under the Transaction Documents or the Certificate of
Designation (a "Material Adverse Effect").  The term  "subsidiaries"  shall mean
entities in which the Company has an equity interest of 50% or greater.

         3.2 Authorization;  Consents.  The Company has the requisite  corporate
power and  authority  to enter into and perform its  obligations  under (i) this
Agreement,  (ii) the Registration Rights Agreement,  (iii) the Warrants and (iv)
all other agreements,  documents, certificates or other instruments executed and
delivered  by or on  behalf  of the  Company  at any  Closing  (the  instruments
described in (i), (ii), (iii) and (iv) being collectively  referred to herein as
the "Transaction  Documents"),  to execute and perform its obligations under the
Certificate  of  Designation,  to issue and sell the  Preferred  Shares  and the
Warrants to the  Purchasers  in accordance  with the terms hereof,  to issue the
Conversion Shares upon conversion of the Preferred Shares in accordance with the
Certificate of Designation  and to issue the Warrant Shares upon exercise of the
Warrants.  All  corporate  action on the part of the  Company  by its  officers,
directors and stockholders  necessary for (A) the  authorization,  execution and
delivery of, and the  performance by the Company of its obligations  under,  the
Transaction Documents,  and (B) the authorization,  execution and filing of, and
the  performance by the Company of its  obligations  under,  the  Certificate of
Designation  has been  taken,  and no further  consent or  authorization  of the
Company,  its Board of Directors,  its stockholders,  any governmental agency or
organization  (other than such approval as may be required  under the Securities
Act and applicable state  securities laws in respect of the Registration  Rights
Agreement),  or any other person or entity is required  (pursuant to any rule of
the National Association of Securities Dealers, Inc. or otherwise).

         3.3  Enforcement.  The  Transaction  Documents and the  Certificate  of
Designation  constitute  valid and legally  binding  obligations of the Company,
enforceable  in  accordance  with  their  respective   terms,   except  as  such
enforcement   may  be  limited  by  (i)   applicable   bankruptcy,   insolvency,
reorganization or other laws of general application relating to or affecting the
enforcement  of  creditors'  rights  generally  and (ii) general  principles  of
equity.

         3.4  Disclosure  Documents;  Agreements;  Financial  Statements;  Other
Information. The Company has filed with the Commission: (i) the Company's Annual
Report on Form 10-K for the year  ended  December  31,  1997,  (ii) a  Quarterly
Report on Form 10-Q for the  quarter  ended  March 31,  1998,  (iii) all Current
Reports on Form 8-K required to be filed with the Commission  since December 31,
1997 and (iv) the  Company's  definitive  Proxy  Statement  for its 1998  Annual
Meeting of Stockholders (collectively,  the "Disclosure Documents"). The Company
is not  aware of any  event  occurring  on or prior to the date of such  Closing
(other than the transactions  effected hereby) that would require the filing of,
or with  respect to which the  Company  intends  to file,  a Form 8-K after such
Closing. Each Disclosure Document, as of the date of the filing thereof with the
Commission, conformed in all
                                      -5-
<PAGE>
material  respects to the  requirements  of the Exchange  Act, and the rules and
regulations  thereunder  and,  as of the date of such  filing,  such  Disclosure
Document did not contain an untrue statement of material fact or omit to state a
material fact required to be stated  therein or necessary to make the statements
therein,  in  light  of the  circumstances  under  which  they  were  made,  not
misleading.  All  material  agreements  required  to be filed as exhibits to the
Disclosure Documents have been filed as required. Neither the Company nor any of
its  subsidiaries  is in  breach of any  agreement  to which it is a party or by
which it is bound  where  such  breach is  reasonably  likely to have a Material
Adverse Effect.  Except as set forth in the Disclosure Documents or any schedule
or exhibit  attached  hereto,  the Company  has no  liabilities,  contingent  or
otherwise,  other than  liabilities  incurred in the ordinary course of business
which, under generally accepted  accounting  principles,  are not required to be
reflected  in  such  financial  statements  and  which,  individually  or in the
aggregate,  are not material to the consolidated business or financial condition
of the Company and its  subsidiaries  taken as a whole.  As of their  respective
dates,  the  financial  statements  of the Company  included  in the  Disclosure
Documents  complied  as  to  form  in  all  material  respects  with  applicable
accounting   requirements  and  the  published  rules  and  regulations  of  the
Commission with respect thereto. Such financial statements have been prepared in
accordance with generally accepted accounting principles consistently applied at
the times and  during  the  periods  involved  (except  (i) as may be  otherwise
indicated in such financial statements or the notes thereto, or (ii) in the case
of unaudited interim statements, to the extent they may exclude footnotes or may
be condensed or summary  statements) and fairly present in all material respects
the financial position of the Company as of the dates thereof and the results of
its operations and cash flows for the periods then ended  (subject,  in the case
of  unaudited  statements,   to  normal  year-end   adjustments).   The  written
information  described  in  paragraph  2.3  above  does not  contain  an  untrue
statement of material fact or omit to state a material fact required in order to
make such information not misleading,  and, except as specifically  disclosed to
such Purchaser, does not include any material, non-public information.

         3.5  Capitalization.  The  capitalization of the Company as of the date
hereof,  including its authorized capital stock, the number of shares issued and
outstanding, the number of shares issuable and reserved for issuance pursuant to
the Company's stock option plans, the number of shares issuable and reserved for
issuance  pursuant to securities  (other than the Preferred  Stock)  exercisable
for, or convertible  into or exchangeable for any shares of Common Stock and the
number of shares  initially to be reserved for issuance  upon  conversion of the
Preferred  Shares and  exercise of the  Warrants  is set forth on  Schedule  3.5
hereto.  All of such  outstanding  shares of capital  stock  have been,  or upon
issuance will be, validly issued,  fully paid and  non-assessable.  No shares of
the capital stock of the Company are subject to  preemptive  rights or any other
similar rights of the  stockholders  of the Company or any liens or encumbrances
created by or through the Company.  Except as  disclosed on Schedule  3.5, or as
contemplated herein, as of the date of this Agreement and as of the date of such
Closing, there are no outstanding options,  warrants, scrip, rights to subscribe
to, calls or commitments of any character  whatsoever relating to, or securities
or rights  convertible  into or exercisable or  exchangeable  for, any shares of
capital  stock of the Company or any of its  subsidiaries,  or  arrangements  by
which the  Company or any of its  subsidiaries  is or may become  bound to issue
additional  shares of capital  stock of the Company or any of its  subsidiaries.
The Purchasers  acknowledge and agree that the  representation and warranty made
in this  paragraph 3.5 does not prohibit the Company from, at any meeting of its
stockholders  from time to time,  amending  an  existing  stock  option  plan or
adopting a 
                                      -6-
<PAGE>
new stock option plan to provide for the grant of options for as much as fifteen
percent  (15%),  in the  aggregate  at any  point in  time,  of the  issued  and
outstanding  shares of Common  Stock,  measured  as of the  record  date for the
meeting at which stockholder  approval for such amended or new stock option plan
is sought.

         3.6 Valid Issuance.  The Preferred Shares are duly authorized and, when
issued, sold and delivered in accordance with the terms hereof, (i) will be duly
and validly issued,  fully paid and nonassessable,  free and clear of any taxes,
liens,  claims,  preemptive  or  similar  rights or  encumbrances  imposed by or
through  the  Company,  (ii)  based  in part  upon the  representations  of each
Purchaser in this  Agreement,  will be issued,  sold and delivered in compliance
with all applicable Federal and state securities laws and (iii) will be entitled
to all of the rights, preferences and privileges set forth in the Certificate of
Designation.  The  Warrants  are duly  authorized  and,  when  issued,  sold and
delivered  in  accordance  with the terms  hereof,  (i) will be duly and validly
issued,  fully  paid and  nonassessable,  free and  clear of any  taxes,  liens,
claims,  preemptive or similar rights or encumbrances  imposed by or through the
Company and (ii) based in part upon the  representations  of each  Purchaser  in
this  Agreement,  will be issued,  sold and  delivered  in  compliance  with all
applicable  Federal and state  securities  laws. The Conversion  Shares are duly
authorized  and reserved for issuance  and,  when issued upon  conversion of the
Preferred Shares in accordance with the terms of the Certificate of Designation,
will be duly and validly issued, fully paid and nonassessable, free and clear of
any taxes, liens,  claims,  preemptive or similar rights or encumbrances imposed
by or through the Company.  The Warrant Shares are duly authorized and, upon the
issuance  thereof in accordance with the terms of the Warrant,  will be duly and
validly  issued,  fully  paid and  nonassessable,  free and clear of any  taxes,
liens,  claims,  preemptive  or  similar  rights or  encumbrances  imposed by or
through the Company.

         3.7 No Conflict with Other Instruments.  Neither the Company nor any of
its subsidiaries is in violation of any provisions of its charter, Bylaws or any
other governing  document or in default (and no event has occurred  which,  with
notice or lapse of time or both, would constitute a default) under any provision
of any instrument or contract to which it is a party or by which it is bound, or
of any provision of any Federal or state judgment, writ, decree, order, statute,
rule or governmental  regulation  applicable to the Company,  which would have a
Material  Adverse  Effect.  The (i) execution,  delivery and performance of this
Agreement and the other Transaction Documents,  (ii) execution and filing of the
Certificate  of  Designation,   and  (iii)   consummation  of  the  transactions
contemplated hereby and thereby (including without  limitation,  the issuance of
the  Preferred  Shares and the  Warrants  and the  reservation  for issuance and
issuance of the Conversion Shares and the Warrant Shares) will not (A) result in
any such  violation or be in conflict  with or  constitute,  with or without the
passage of time and giving of notice, either a default under any such provision,
instrument  or contract or an event which  results in the  creation of any lien,
charge  or  encumbrance  upon  any  assets  of  the  Company  or of  any  of its
subsidiaries  or the  triggering of any  preemptive or  anti-dilution  rights or
rights of first  refusal or first offer on the part of holders of the  Company's
securities or (B) cause any  Purchaser,  or any affiliate of such  Purchaser (in
either such case, alone or together with any other  Purchaser),  to be deemed to
be an Acquiring Person,  as such term is defined in the Rights Agreement,  dated
as of March 4, 1997,  between the Company and the Bank of New York (the  "Rights
Plan") or trigger any rights under the Rights Plan.  Each  Conversion  Share and
Warrant  Share  shall be  entitled  to all of the rights  afforded  to shares of
Common Stock under the Rights Plan.
                                      -7-

                  3.8.1 The  Company's  financial  condition is, in all material
respects,  as described in the Disclosure  Documents,  except for changes in the
ordinary course of business and normal year-end adjustments that are not, in the
aggregate,   materially  adverse  to  the  consolidated  business  or  financial
condition  of the  Company  and its  subsidiaries  taken as a whole.  Except  as
otherwise  described  in the  Disclosure  Documents,  there has been no material
adverse  change to the Company's  business,  operations,  properties,  financial
condition,  prospects or results of  operations  since the date of the Company's
most recent audited financial statements contained in the Disclosure Documents.

                  3.8.2 The  Company  has filed all tax  returns  required to be
filed  by it and  paid all  taxes  which  are due,  except  for  taxes  which it
reasonably disputes or which could not reasonably be expected to have a Material
Adverse Effect.

                  3.8.3  Except  as set forth on  Schedule  3.8.3,  neither  the
Company  nor any of its  subsidiaries  is the  subject of any pending or, to the
Company's  knowledge,  threatened  inquiry,  investigation or  administrative or
legal proceeding by the Internal Revenue Service,  the taxing authorities of any
state or local jurisdiction,  the Commission or any state securities  commission
or other governmental or regulatory entity.

                  3.8.4  Except as  described  on  Schedule  3.8.4,  there is no
material claim,  litigation or  administrative  proceeding  pending,  or, to the
Company's knowledge,  threatened or contemplated,  against the Company or any of
its subsidiaries, or against any officer, director or employee of the Company or
any such  subsidiary in  connection  with such  person's  employment  therewith.
Neither the Company nor any of its  subsidiaries is a party to or subject to the
provisions of, any order, writ,  injunction,  judgment or decree of any court or
government agency or instrumentality  which could reasonably be expected to have
a Material Adverse Effect.

         3.9  Reporting  Company;  Form  S-3.  The  Company  is  subject  to the
reporting requirements of the Exchange Act, has a class of securities registered
under  Section  12 of the  Exchange  Act,  and has  filed all  reports  required
thereby.  The Company will be, as of  September 1, 1998,  eligible to register a
primary  issuance of shares of its Common Stock on a  registration  statement on
Form S-3 under the Securities Act.

         3.10  Acknowledgement  of Dilution.  The Company  acknowledges that the
issuance of the  Conversion  Shares upon  conversion of the Preferred  Shares in
accordance  with the terms of the Certificate of Designation and the issuance of
the Warrant  Shares upon  exercise of the Warrants may result in dilution of the
outstanding  shares of Common Stock,  which  dilution may be  substantial  under
certain market conditions.  The Company further acknowledges that its obligation
to issue Conversion  Shares upon conversion of the Preferred Shares and to issue
Warrant  Shares upon  exercise of the  Warrants is  unconditional  and  absolute
regardless of the effect of any such dilution.

         3.11 Intellectual  Property. The Company and its subsidiaries each owns
or possesses  
                                      -8-
<PAGE>
adequate  trademarks,  trade  names and other  rights to  inventions,  know-how,
patents,  copyrights,  confidential  information and other intellectual property
rights  necessary to conduct the business now operated by it (the  "Intellectual
Property  Rights"),  and is not aware of any  infringement by a third party with
respect to such rights or of any  infringement  by it or conflict  with asserted
rights of others that, in any such case, if determined  adversely to the Company
or  any of its  subsidiaries,  would  individually  or in the  aggregate  have a
Material  Adverse  Effect.  The  Intellectual  Property  Rights  are  valid  and
enforceable  and  no  registration  relating  thereto  has  lapsed,  expired  or
terminated or is the subject of any claim or proceeding that could result in any
such lapse, expiration or termination. The Company and its subsidiaries each has
complied in all material respects with its obligations pursuant to any agreement
relating to the  Intellectual  Property  Rights that are the subject of licenses
granted by third parties.

         3.12 Registration Rights; Rights of Participation.  Except as described
on Schedule  3.12 hereto,  (A) the Company has not granted or agreed to grant to
any person or entity any rights (including "piggy-back"  registration rights) to
have any securities of the Company  registered  with the Commission or any other
governmental authority which has not been satisfied and (B) no person or entity,
including,  but not limited to, current or former  stockholders  of the Company,
underwriters,  brokers,  agents or other third  parties,  has any right of first
refusal,  preemptive  right,  right of  participation,  or any similar  right to
participate  in the  transactions  contemplated  by this  Agreement,  the  other
Transaction  Documents  or the  Certificate  of  Designation  which has not been
waived.

         3.13 Trading on Nasdaq. The Common Stock is authorized for quotation on
the Nasdaq  National  Market,  and trading in the Common Stock on Nasdaq has not
been suspended. The Company is in full compliance with the continued designation
criteria of the Nasdaq National Market, and does not reasonably  anticipate that
the Common Stock will lose its designation as a Nasdaq National Market Security,
whether by reason of the transactions  contemplated by this Agreement, the other
Transaction Documents or the Certificate of Designation, and is not aware of any
inquiry by or received any notice from the National  Association  of  Securities
Dealers,  Inc. ("NASD")  regarding any failure or alleged failure by the Company
to comply with such criteria.

         3.14  Solicitation.  Neither the Company nor any of its subsidiaries or
affiliates, nor any person acting on its or their behalf, (i) has engaged in any
form of general  solicitation  or general  advertising  (within  the  meaning of
Regulation  D) in connection  with the offer or sale of the Preferred  Shares or
(ii) has,  directly or  indirectly,  made any offers or sales of any security or
solicited any offers to buy any  security,  under any  circumstances  that would
require registration of the Preferred Shares under the Securities Act.

         3.15 Fees. Except as described on Schedule 3.15 hereto,  the Company is
not obligated to pay any compensation or other fee, cost or related  expenditure
to any underwriter, broker, agent or other representative in connection with the
transactions contemplated hereby.

         3.16  Foreign  Corrupt  Practices.  To the  knowledge  of the  Company,
neither the Company,  nor any of its  subsidiaries  nor any  director,  officer,
agent,  employee  or  other  person  acting  on  behalf  of the  Company  or any
subsidiary,  has (i) used any  corporate  funds for any  unlawful  contribution,
gift,  entertainment or other unlawful expenses relating to political  activity,
(ii) made any direct or indirect  
                                      -9-
<PAGE>
unlawful payment to any foreign or domestic government official or employee,  or
(iii)  violated any provision of the Foreign  Corrupt  Practices Act of 1977, as
amended, or made any bribe, rebate, payoff, influence payment, kickback or other
unlawful payment to any foreign or domestic government official or employee.

         3.17 Other  Issuances  of  Securities.  The Company has not issued (and
will not issue) any shares of Common  Stock or shares of any series of preferred
stock or other securities or instruments  convertible into,  exchangeable for or
otherwise  entitling the holder  thereof to acquire shares of Common Stock which
would be integrated with the sale of the Preferred Shares to the Purchasers,  or
the issuance of the Conversion Shares upon conversion  thereof,  for purposes of
determining  whether  stockholder  approval  is required  under the  designation
criteria of the Nasdaq National Market or otherwise.

         3.18 Title. The Company and its  subsidiaries  have good and marketable
title in fee simple to all real  property and good and  marketable  title to all
personal property owned by them which is material to the business of the Company
and its  subsidiaries,  in each  case  free  and  clear  of all  liens,  claims,
encumbrances  and defects,  except for liens,  claims,  encumbrances  or defects
which do not  materially  affect the value of such property and do not interfere
with the use made or proposed to be made of such property by the Company and its
subsidiaries.  Any real property and facilities  held under lease by the Company
and its  subsidiaries  are held by them under valid,  subsisting and enforceable
leases with such  exceptions as are not material and do not  interfere  with the
use made or proposed to be made of such  property  and  buildings by the Company
and its subsidiaries.

         3.19 Regulatory Permits.  The Company and its subsidiaries  possess all
certificates,  authorizations  and permits  issued by the  appropriate  federal,
state or foreign  regulatory  authorities  necessary to conduct their respective
businesses,  and neither the Company nor any such  subsidiary  has  received any
notice of  proceedings  relating to the revocation or  modification  of any such
certificate, authorization or permit.

4. COVENANTS OF THE COMPANY AND THE PURCHASERS.
   -------------------------------------------

         4.1 Corporate Existence. The Company shall, so long as any Purchaser or
any affiliate of such Purchaser  beneficially owns any Securities,  maintain its
corporate existence in good standing and shall pay all taxes owed by it when due
except  for  taxes  which the  Company  reasonably  disputes  or as to which the
failure to pay could not  reasonably  be  expected  to have a  Material  Adverse
Effect.

         4.2 Provision of Information.  The Company shall provide each Purchaser
with copies of its annual reports on Form 10-K,  quarterly reports on Form 10-Q,
current  reports on Form 8-K,  press  releases  and proxy  statements  and other
materials  sent to  stockholders,  in each such case  promptly  after the filing
thereof with the  Commission,  until the  conversion or redemption of all of the
Preferred Shares.

         4.3 Form D; Blue-Sky Qualification. The Company agrees to file a Form D
with respect to the Securities as required  under  Regulation D and to provide a
copy thereof to each Purchaser promptly

<PAGE>
after such filing.  The Company shall,  on or before the Tranche A Closing Date,
take such action as is necessary to qualify the Preferred  Shares for sale under
applicable state or "blue-sky" laws or obtain an exemption therefrom,  and shall
provide  evidence  of any  such  action  to each  Purchaser  at or prior to each

         4.4 Reporting Status. As long as any Purchaser or any affiliate of such
Purchaser  beneficially  owns any  Securities and until the date on which any of
the  foregoing  may be sold  to the  public  pursuant  to  Rule  144(k)  (or any
successor  rule or  regulation),  (i) the  Company  shall  timely  file with the
Commission all reports  required to be so filed pursuant to the Exchange Act and
(ii) the Company  shall not  terminate  its status as an issuer  required by the
Exchange Act to file reports thereunder even if the Exchange Act or the rules or
regulations thereunder would permit such termination. The Company agrees to file
with  the  Commission  a Form  8-K  describing  the  terms  of the  transactions
contemplated  by this Agreement and the other  Transaction  Documents,  with the
Transaction  Documents  attached to such Form 8-K as an exhibit  thereto,  on or
before the tenth  (10th) day  following  the Tranche A Closing  Date in the form
required  by the  Exchange  Act.  On or  before  the  business  day  immediately
following a Closing,  the Company agrees to issue a press release describing all
of the material terms of the transaction consummated at such Closing.

         4.5  Reservation  of Common Stock.  The Company shall at all times have
authorized and reserved for issuance,  free from any preemptive  rights,  solely
for the purpose of effecting conversions of the Preferred Shares and exercise of
the  Warrants,  such number of its shares of Common  Stock as shall from time to
time be sufficient to effect the  conversion of all of the Preferred  Shares and
exercise of all of the Warrants then outstanding (the "Reserved Amount").  As of
the Tranche A Closing Date,  the Reserved  Amount shall be equal to no less than
175% of the number of shares of Common Stock issuable upon  conversion of all of
the  Preferred  Shares and  exercise of all of the  Warrants to be issued at the
Tranche A Closing  (assuming  for such purpose that such  conversion or exercise
were to occur as of the  Tranche A Closing  Date).  If on any date the  Reserved
Amount is less than 150% of the number of shares of Common  Stock then  issuable
upon  conversion  of all of the  Preferred  Shares  and  exercise  of all of the
Warrants then  outstanding  (assuming  for such purpose that such  conversion or
exercise  were  to  occur  as of such  date),  the  Company  shall  take  action
(including without limitation seeking stockholder approval for the authorization
or reservation of additional shares of Common Stock) as soon as practicable (but
in no event  later  than the fifth  (5th)  business  day or,  in the event  that
stockholder  approval is required,  the sixtieth (60th) day following such date)
to increase the Reserved  Amount to no less than 175% of the number of shares of
Common Stock into which such  outstanding  Preferred Shares are then convertible
and such outstanding Warrants are exercisable.  The Company shall not reduce the
number of shares reserved for issuance  hereunder without the written consent of
the  holders  of  two-thirds  of the  Preferred  Shares  then  outstanding.  Any
determination made hereunder as to the number of shares of Common Stock issuable
upon the  conversion of Preferred  Shares or exercise of Warrants  shall be made
without  regard to any  restriction  on such  conversion  or exercise that might
otherwise exist under this  Agreement,  the other  Transaction  Documents or the
Certificate of Designation.  The initial  Reserved Amount shall be allocated pro
rata among the Purchasers based on the number of Preferred Shares issued to each
Purchaser at the Tranche A Closing.  Each increase in the Reserved  Amount shall
be allocated pro rata among the Holders based on the number of Preferred  Shares
held by such  Holder at the time of such  increase.  In the event  that a Holder
shall sell or 
                                      -11-
<PAGE>
otherwise transfer any of such Holder's Preferred Shares,  each transferee shall
be  allocated  a pro rata  portion of such  transferor's  Reserved  Amount.  Any
portion of the Reserved  Amount which remains  allocated to any person or entity
which does not hold any  Preferred  Shares shall be  allocated to the  remaining
Holders  pro rata  based on the  number of  Preferred  Shares  then held by such
Holders.

         4.6 Use of Proceeds.  The Company  shall use the proceeds from the sale
of the Preferred  Shares for general  corporate  purposes  only, in the ordinary
course of its business and consistent with past practice, and shall not use such
proceeds to make a loan to any  employee,  officer or director of the Company or
to repurchase or pay a dividend on shares of Common Stock.

         4.7  Transactions   with  Affiliates.   The  Company  agrees  that  any
transaction  or  arrangement  between  it or  any of its  subsidiaries  and  any
affiliate or employee of the Company  shall be effected on an arms' length basis
in  accordance  with  customary  commercial  practice and shall be approved by a
majority of the Company's outside directors.

         4.8 Quotation on Nasdaq.  The Company shall (i) promptly  following the
Tranche  A  Closing,  take  such  action  as may be  necessary  to  include  the
Conversion Shares and the Warrant Shares on the Nasdaq National Market, and (ii)
use its best efforts to maintain the designation and quotation,  or listing,  of
the Common Stock on the Nasdaq National  Market,  the New York Stock Exchange or
the American Stock Exchange.

         4.9 Use of Purchaser Name. Except as may be required by applicable law,
the Company shall not use,  directly or indirectly,  any Purchaser's name or the
name of any of its affiliates in any advertisement,  announcement, press release
or other similar  communication unless it has received the prior written consent
of any Purchaser for the specific use  contemplated or as otherwise  required by
applicable law or regulation.

         4.10  Company's  Instructions  to  Transfer  Agent.  On or prior to the
Tranche A Closing  Date,  the Company  shall  execute  and  deliver  irrevocable
instructions  to  its  transfer  agent  (the  "Transfer  Agent")  (i)  to  issue
certificates  representing  Conversion  Shares upon  conversion of the Preferred
Shares  in  accordance  with the terms of the  Certificate  of  Designation  and
receipt  of a  valid  Conversion  Notice  (as  defined  in  the  Certificate  of
Designation)  from a  Purchaser,  in the  amount  specified  in such  Conversion
Notice, in the name of such Purchaser or its nominee, (ii) to issue certificates
representing  Warrant  Shares upon exercise of the Warrants and (iii) to deliver
such  certificates  to such Purchaser no later than the close of business on the
third (3rd)  business day following the related  Conversion  Date (as defined in
the Certificate of Designation) or Exercise Date (as defined in the Warrant), as
the case may be. As long as the Company shall  instruct the transfer agent that,
in lieu of delivering physical certificates  representing shares of Common Stock
to a Purchaser  upon  conversion  of the  Preferred  Shares,  or exercise of the
Warrants,  and as long as the Transfer  Agent is a participant in the Depository
Trust Company  ("DTC") Fast  Automated  Securities  Transfer  program,  and such
Purchaser  has not  informed  the  Company  that it wishes to  receive  physical
certificates  therefor,  the transfer  agent may effect  delivery of  Conversion
Shares or Warrant  Shares,  as the case may be, by crediting the account of such
Purchaser  or its nominee at DTC for the number of shares for which  delivery is
required  hereunder  within  the time  frame  specified  above for  delivery  of
certificates. The Company represents 
                                      -12-
<PAGE>
to and agrees with each Purchaser  that it will not give any  instruction to the
Transfer  Agent that will conflict with the foregoing  instruction  or otherwise
restrict such  Purchaser's  right to convert the Preferred  Shares or to receive
Conversion Shares in accordance with the terms of the Certificate of Designation
or to exercise  the Warrant or to receive  Warrant  Shares upon  exercise of the
Warrants.  In the event that the Company's  relationship with the Transfer Agent
should be terminated  for any reason,  the Company shall use its best efforts to
cause the Transfer  Agent to continue  acting as transfer  agent pursuant to the
terms hereof until such time that a successor transfer agent is appointed by the
Company and receives the instructions described above.

         4.11 Capital Raising Limitation;  Registration Limitation.  The Company
will not,  during the one  hundred  and eighty  (180) day period  following  the
Tranche A Closing  Date and,  if the  Tranche B Closing  occurs,  following  the
Tranche B Closing Date, offer for sale or sell any Common Stock (or any security
convertible  into,  or  exercisable  or  exchangeable  for,  Common  Stock) (the
"Capital Raising Limitation").  The Company will not, during the two hundred and
seventy  (270) day  period  following  the  effective  date of the  Registration
Statement (as defined in the Registration Rights Agreement), register any shares
of Common Stock  otherwise than pursuant to the  Registration  Rights  Agreement
(the  "Registration  Limitation").   The  Capital  Raising  Limitation  and  the
Registration  Limitation  shall  not  apply  to any  transaction  involving  the
issuance of Common Stock in a  firm-commitment  underwritten  registered  public
offering, to the issuance of Common Stock pursuant to a warrant exercise for any
warrant outstanding prior to the date hereof or the grant or exercise of options
for Common Stock  granted  pursuant to one or more stock option plans (such plan
or plans to be subject to the  limitations  described in  paragraph  3.5 hereof)
approved by the stockholders of the Company.

         4.12 Right of First Offer. Prior to any offer or sale by the Company of
Common Stock (or any securities  convertible or exercisable into or exchangeable
for Common Stock) during the one (1) year period following the Tranche A Closing
Date and, if the Tranche B Closing occurs,  following the Tranche B Closing Date
(the "First Offer  Period"),  the Company must first  deliver to each  Purchaser
written  notice  describing  the  proposed  issuance,  including  the  terms and
conditions  thereof,  and provide such  Purchaser with an option during the five
(5) business day period following  delivery of such notice to purchase up to its
proportionate  share (based on the number of Preferred  Shares purchased by such
Purchaser  hereunder relative to the number of Preferred Shares purchased by all
of the Purchasers  hereunder) of the securities  being offered on the same terms
as contemplated by such issuance.  In the event that such Purchaser  either does
not give notice within such five business day period that it intends to exercise
the  foregoing  option or informs the Company in writing that it does not intend
to  participate  in such  issuance,  the  Company may offer to a third party the
option to purchase up to, in the aggregate,  the amount of securities which were
declined by such Purchaser, on the same terms as were offered to such Purchaser.
The  Right of First  Offer  shall  not apply to any  transaction  involving  the
issuance of Common Stock in a  firm-commitment  underwritten  registered  public
offering or to a warrant exercise for any warrant  outstanding prior to the date
hereof or to the  issuance  of Common  Stock  pursuant  to a stock  option  plan
adopted by the Company prior to the date hereof.

         4.13 No Adverse Action. The Company and its subsidiaries shall refrain,
while any Preferred Shares are  outstanding,  from taking any action or entering
into  any  arrangement  which  in any way  adversely  affects  (i)  the  rights,
privileges or benefits available to a holder of Preferred Stock pursuant to
                                      -13-
<PAGE>
the terms of the  Certificate of  Designation or (ii) the rights,  privileges or
benefits available to a holder of a Warrant.

         4.14 Short Sales.  Each Purchaser  agrees that will not create a "short
position" in the Common Stock at any time  following  the Tranche A Closing Date
until the earlier of (a) the fourth (4th)  anniversary  of the later to occur of
the Tranche A Closing Date and the Tranche B Closing Date and (b) the first date
on which such  Purchaser  no longer  owns any  Preferred  Shares.  For  purposes
hereof,  a "short  position" shall be deemed to have been created by a Purchaser
if such  Purchaser  (i) enters  into a "short  sale" (as such term is defined in
Rule 3(b)(3) under the Exchange Act), (ii) purchases a put option to sell shares
of Common Stock or (iii) enters into a derivative or other  similar  transaction
whereby  such  Purchaser  will be  compensated  in the event of a decline in the
price of the Common Stock;  provided,  however, that such term shall not include
any short sales  effected  (A) as a result of the  Company's  failure to deliver
Conversion  Shares or Warrant Shares, as the case may be, in accordance with the
terms of the  Certificate of Designation or Warrant,  respectively or (B) on the
same day (or on the  immediately  preceding  Trading  Day) on which a Conversion
Notice (as defined in the  Certificate  of  Designation)  is  delivered  by such
Purchaser to the Company.

         4.15 Obligation to Hold Annual Stockholder  Meeting. The Company agrees
that, on or prior to May 31, 1999, it will hold a meeting of its stockholders at
which it will recommend, and will otherwise use its best efforts to ensure, that
such  stockholders (i) approve the transactions  contemplated by this Agreement,
the other  Transaction  Documents and the  Certificate of  Designation  and (ii)
increase  the  Company's  authorized  Common  Stock  and out of  such  increase,
increase the Reserved  Amount by no less than the greater of seven  million five
hundred  thousand  (7,500,000)  shares of Common Stock and one hundred and fifty
percent (150%) of the number of shares of Common Stock issuable upon  conversion
of all of the Preferred  Shares and exercise of the Warrants  outstanding on the
date the proxy  statement  relating to such meeting is filed with the Commission
(assuming  such  conversion or exercise is effected at the  Conversion  Price or
Exercise  Price then in effect and without  regard to any  restrictions  on such
conversion or exercise that might otherwise  exist);  provided,  however that if
such approval is not obtained by May 31, 1999, and at any time  thereafter,  the
sum of (i) the number of shares of Common Stock issuable upon  conversion of all
of the  then  outstanding  Preferred  Shares  and  exercise  of the  outstanding
Warrants  (assuming  such  conversion or exercise is effected at the  Conversion
Price or Exercise Price then in effect and without regard to any restrictions on
such conversion or exercise that might otherwise  exist) plus (ii) the aggregate
number of shares of Common  Stock  theretofore  issued  upon  conversion  of the
Preferred  Shares and  exercise of the Warrants is equal to or greater than five
million  (5,000,000)  shares of Common Stock (the "Conversion Limit Amount") for
five consecutive Trading Days, each Purchaser shall have the right, upon written
notice  to the  Company,  to  require  the  Company  to  redeem a number of such
Purchaser's Preferred Shares such that, immediately following such redemption (a
"Conversion  Limit  Redemption"),  such  Purchaser's  allocable  portion  of the
Conversion  Limit Amount (such allocable  portion to be determined  based on the
number of Preferred Shares purchased by such Purchaser hereunder relative to the
aggregate  number of Preferred  Shares  purchased by the  Purchasers  hereunder)
represents  no less than one hundred and fifty  percent  (150%) of the number of
shares of Common Stock  issuable upon  conversion  of the  Preferred  Shares and
exercise of the Warrants then held by such Purchaser  (assuming such  conversion
or exercise is effected at the Conversion Price or Exercise Price then in effect
and without 
                                      -14-
<PAGE>
regard to any  restrictions  on such conversion or exercise that might otherwise
exist).  For purposes of clarification,  the parties  acknowledge and agree that
each  Purchaser  shall have the right to require a Conversion  Limit  Redemption
each and every time that the conditions set forth in this paragraph 4.15 to such
redemption  exist.  The  Company  shall,  within five (5)  business  days of its
receipt from a Purchaser of a notice  requesting a Conversion Limit  Redemption,
redeem the number of Preferred  Shares subject to such  redemption by delivering
to  such  Purchaser  immediately  available  funds  in an  amount  equal  to the
Conversion Limit Redemption Price. Any amounts representing the Conversion Limit
Redemption  Price  which are not paid when due shall bear  interest at an annual
rate  equal to the  Default  Interest  Rate (as  defined in the  Certificate  of
Designation).  For purposes hereof, the "Conversion Limit Redemption Price" with
respect  to a  Preferred  Share  shall be equal to (a)  during  the first  three
hundred  and sixty  (360) days  following  the  Closing  Date  relating  to such
Preferred  Share,  108.5% of the Stated  Value of such  Preferred  Share and (b)
following  the last day of such three  hundred and sixtieth day period,  a price
that is  calculated so that the holder of such  Preferred  Share will receive an
annualized return on the Stated Value of such Preferred Share of 8.5%. The right
of a Purchaser to require a Conversion  Limit  Redemption  in the  circumstances
described  herein will be in addition to any other rights or remedies  available
to such Purchaser in such circumstances, whether at law or in equity, under this
Agreement, the other Transaction Documents or the Certificate of Designation.

         4.16 Obligation to Hold Special Stockholder  Meeting. In the event that
a "Material  Adverse Event" (as defined in paragraph 4(a) of the  Certificate of
Designation) occurs, (A) the Company will have the right, upon written notice (a
"Material  Adverse Event  Notice")  delivered to the Holders during the five (5)
day period immediately  following the occurrence of a Material Adverse Event, to
redeem all of the Preferred  Shares then outstanding at a redemption price equal
to the Conversion  Limit Redemption Price for each Preferred Share (an "Optional
Redemption"),  and deliver  funds  representing  such  redemption  price to each
Purchaser within three (3) business days following such five day period,  (B) if
the Company  does not  exercise  its right to an Optional  Redemption,  it must,
within  sixty days  following  the end of such five day  period,  hold a special
meeting of its  stockholders at which it will recommend,  and will otherwise use
its best  efforts to ensure,  that such  stockholders  approve the  transactions
contemplated  by  this  Agreement,  the  other  Transaction  Documents  and  the
Certificate  of  Designation  and  authorize for issuance by the Company no less
than either (i) seven  million  five  hundred  thousand  (7,500,000)  additional
shares of Common  Stock,  or (ii) one  hundred and fifty  percent  (150%) of the
number  of  shares  of  Common  Stock  issuable  upon  conversion  of all of the
Preferred  Shares  outstanding on the date that the proxy statement  relating to
such meeting is filed with the Commission,  and (C) if the Company does not hold
such special  meeting within the time period  specified in clause (B) above,  or
the  stockholders  do not approve the  proposals  described in clause (B) above,
such failure will be deemed to constitute a Mandatory Redemption Event under the
Certificate of Designation.  Notwithstanding the foregoing, each Purchaser shall
have the right,  upon  receipt by such  Purchaser  of a Material  Adverse  Event
Notice  from the  Company,  to notify the  Company in  writing  within  five (5)
business  days  following  such receipt that the Company will not be required to
seek the stockholder  approval  described in clause (B) above, in which case the
Company will no longer have the right to redeem any Preferred Shares pursuant to
clause (A) above.

6. MISCELLANEOUS.
   -------------

                  6.1 Survival;  Severability. The representations,  warranties,
covenants and indemnities  made by the parties herein shall survive each Closing
notwithstanding  any due  diligence  investigation  made by or on  behalf of the
party seeking to rely thereon. In the event that any provision of this Agreement
becomes or is  declared  by a court of  competent  jurisdiction  to be  illegal,
unenforceable  or void,  this Agreement  shall continue in full force and effect
without said  provision;  provided that in such case the parties shall negotiate
in good  faith to  replace  such  provision  with a new  provision  which is not
illegal,  unenforceable  or  void,  as long  as  such  new  provision  does  not
materially change the economic benefits of this Agreement to the parties.

                  6.2 Successors  and Assigns.  The terms and conditions of this
Agreement  shall  inure to the  benefit  of and be binding  upon the  respective
successors and permitted assigns of the parties.
                                      -19-
<PAGE>
Nothing in this  Agreement,  express or implied,  is intended to confer upon any
party other than the parties hereto or their respective successors and permitted
assigns any rights,  remedies,  obligations or liabilities under or by reason of
this Agreement,  except as expressly  provided in this Agreement.  The Purchaser
may assign its rights and obligations hereunder,  in connection with any private
sale or transfer of the Preferred Shares in accordance with the terms hereof, as
long as, as a condition  precedent to such transfer,  the transferee executes an
acknowledgment  agreeing  to be  bound  by the  applicable  provisions  of  this
Agreement,  in which case the term "Purchaser"  shall be deemed to refer to such
transferee as though such  transferee  were an original  signatory  hereto.  The
Company may not assign it rights or obligations under this Agreement.

                   6.3 No Reliance. Each party acknowledges that (i) it has such
knowledge in business and financial matters as to be fully capable of evaluating
this  Agreement,   the  other   Transaction   Documents  and  the   transactions
contemplated  hereby  and  thereby,  (ii) it is not  relying  on any  advice  or
representation  of any  other  party  in  connection  with  entering  into  this
Agreement,  the other Transaction Documents or such transactions (other than the
representations  made in this  Agreement  or the other  Transaction  Documents),
(iii) it has not received  from such party any  assurance or guarantee as to the
merits (whether legal, regulatory, tax, financial or otherwise) of entering into
this  Agreement or the other  Transaction  Documents or the  performance  of its
obligations  hereunder and  thereunder,  and (iv) it has consulted  with its own
legal, regulatory, tax, business, investment,  financial and accounting advisors
to the extent that it has deemed necessary,  and has entered into this Agreement
and the other Transaction Documents based on its own independent judgment and on
the  advice of its  advisors  as it has  deemed  necessary,  and not on any view
(whether written or oral) expressed by such other party.

                  6.4 Independent Nature of Purchasers'  Obligations and Rights.
The  obligations of each Purchaser  hereunder are several and not joint with the
obligations  of the  other  Purchasers  hereunder,  and no  Purchaser  shall  be
responsible  in any way for the  performance  of the  obligations  of any  other
Purchaser  hereunder.  Nothing  contained  herein or in any other  agreement  or
document delivered at the Closing, and no action taken by any Purchaser pursuant
hereto  or  thereto,   shall  be  deemed  to  constitute  the  Purchasers  as  a
partnership,  an  association,  a joint venture or any other kind of entity,  or
create a presumption  that the  Purchasers are in any way acting in concert with
respect to such obligations or the transactions  contemplated by this Agreement.
Each  Purchaser  shall be entitled to protect and enforce its rights,  including
without  limitation the rights arising out of this Agreement or out of the other
Transaction Documents,  and it shall not be necessary for any other Purchaser to
be joined as an additional party in any proceeding for such purpose.
