                           a Canadian chartered bank,

                           (hereinafter referred to as the "Bank")

                                                          OF THE FIRST PART,

                                  - AND -

                           ANALOGIC CORPORATION,
                           a corporation incorporated under the laws
                           of the State of Massachussetts,

                           (hereinafter referred to as "Analogic")

                                                          OF THE SECOND PART

WHEREAS:

         (a)   Pursuant to a commitment letter dated January 12, 2001 (the
               "Original Commitment Letter") the Bank made the following
               credit facilities (together the "Original Credit
               Facilities") available to Cedara Software Corp. (the
               "Company"):

               (i)    revolving line of credit up to the maximum principal
                      amount of $12,000,000.00, subject to margin
                      availability;

               (ii)   landlord letter of credit facility in the amount of
                      $667,000.00;

               (iii)  non-revolving facility in the maximum amount of
                      $1,000,000.00; and

               (iv)   business mastercard facility limited to $100,000.00;

         (b)   Pursuant to a Commitment Letter dated January 7, 2002 and
               attached as Schedule A hereto (the "Commitment Letter"), the
               Original Credit Facilities have been replaced and superceded
               by the following credit facilities (together, the "Credit
               Facilities"):

               (i)    revolving line of credit limited to the maximum
                      principal amount of $9,000,000.00, with no limitation

               (iii)  business mastercard facility in the maximum amount of
                      $100,000.00;

         (c)   Advances to the Company by the Bank under the Credit
               Facilities shall vary from time to time but shall not exceed
               $10,000,000. All indebtedness of the Company to the Bank
               under the Credit Facilities inclusive of interest and costs
               shall be referred to herein as the "Indebtedness";

         (d)   The Company has executed and delivered in favour of the Bank
               the security as summarized in Schedule "B" attached hereto
               (collectively referred to herein as the "Security"), as
               general and continuing security for the payment of the
               Indebtedness;

         (e)   To secure Analogic's obligations to the Bank under this
               agreement, Analogic has arranged for delivery to the Bank of
               a standby letter of credit (the "Letter of Credit") from
               Sovereign Bank of Boston, confirmed by Bank of New York in
               the amount of $10,000,000.00; and

         (f)   The Bank has agreed to sell, transfer and assign the
               Indebtedness and the Security to Analogic on the terms
               described herein.


NOW THEREFORE in consideration of the payment by Analogic to the Bank of
the sum of $10.00 TEN DOLLARS, the mutual covenants and agreements
contained herein, and for other good and valuable consideration, the
receipt and sufficiency of which are acknowledged by each party to the
other, the parties hereto agree as follows:

1.       Notwithstanding anything to the contrary contained in this
         Agreement, so long as any Indebtedness is outstanding, (a) the
         Bank shall be permitted to make a demand for payment under the
         Letter of Credit (a "Demand") at any time without any prior notice
         to Analogic or the Company and (b) nothing contained herein shall
         limit the Bank's ability or right to make a Demand or to receive
         payment under the Letter of Credit.

2.       Following a Demand, the Bank shall use its best efforts to notify
         Analogic within two (2) business days (being a day, other than a
         Saturday, Sunday or public holiday, on which banks are open for
         business in the cities of Toronto and Boston ) (a "Business Day")
         in accordance with the terms of this Agreement that a Demand has
         been made. The Bank shall have no liability to Analogic nor shall
         any of the Bank's rights under this Agreement be affected in the
         event that the Bank fails to provide such notice to Analogic.

3.       Analogic hereby offers (the "Offer") to purchase the Indebtedness
         and the Security from the Bank on the terms and conditions set
         forth in this agreement and in Schedule C. Upon a Demand being
         made by the Bank, the Bank shall be deemed to have accepted the
         Offer. The purchase price payable by Analogic for the purchase of
         the Indebtedness and Security (the "Purchase Price") shall be the
         amount of the Indebtedness as at the L/C Closing Date (as defined
         below) and the funds received by the Bank in satisfaction of the
         Demand shall be on account of the Purchase Price. The closing of
         the purchase and sale of the Indebtedness and Security following a
         Demand being made by the Bank shall be the date upon which the
         Bank receives immediately available funds under the Letter of
         Credit in accordance with the Demand (the "L/C Closing Date") in
         an amount equal to the Indebtedness provided, however, that if the
         funds paid to the Bank under the Letter of Credit are not equal to
         the Indebtedness, then the L/C Closing Date shall be extended
         until such time as Analogic pays to the Bank the balance of the
         Indebtedness, current to the date of such payment by way of wire
         transfer, certified funds drawn on a Canadian chartered bank or
         other immediately available funds. On the L/C Closing Date, the
         Bank shall be deemed to have sold, transferred and assigned the
         Indebtedness and Security to Analogic, and Analogic shall be
         deemed to have paid the Purchase Price, all on the terms and
         conditions set forth in this agreement and in Schedule C without
         any further act of either party being required to complete such
         sale, transfer and assignment.

4.       For greater certainty, the parties acknowledge that amounts
         received by the Bank pursuant to a Demand shall be on account of
         the Purchase Price and not on account of the Indebtedness.

5.       If, following the L/C Closing Date, the Letter of Credit is not
         fully drawn, the Bank shall return the Letter of Credit to
         Analogic forthwith.

6.       Analogic shall be entitled at any time to require the Bank by
         delivery of a written notice to the Bank (the "Call Notice")
         delivered at any time after the date of this Agreement in
         accordance with the terms hereof, and the Bank hereby agrees, to
         sell to Analogic the Indebtedness and the Security (the "Call
         Right") on the terms and conditions set forth in Schedule C.

7.       The purchase price payable by Analogic upon any exercise of the
         Call Right (the "Call Right Purchase Price") shall be an amount
         equal to the Indebtedness determined as of the Call Right Closing
         Date (as defined below). Analogic may not exercise the Call Right
         once a Demand has been made by the Bank.

8.       The completion of the purchase and sale of the Indebtedness and
         Security pursuant to any exercise of the Call Right shall be
         completed on the fifth Business Day following receipt by the Bank
         of a Call Notice (the "Call Right Closing Date"). On the Call
         Right Closing Date, upon payment of the Call Right Purchase Price
         by Analogic to the Bank by way of wire transfer, certified funds
         drawn on a Canadian chartered bank or other immediately available
         funds or as may otherwise be agreed by the parties, the Bank shall
         be deemed to have sold, transferred and assigned the Indebtedness
         and Security to Analogic on the terms and conditions set forth in
         this agreement and in Schedule C without any further act of either
         party being required to complete such sale, transfer and
         assignment.

9.       The delivery to the Bank of a Call Notice shall not prohibit the
         Bank from making a Demand. In the event that the Bank makes a
         Demand following the receipt by the Bank of a Call Notice and
         prior to payment to the Bank of the Call Right Purchase Price, the
         provisions of Article 3 of this Agreement shall govern the
         purchase of the Indebtedness and the Security by Analogic from the
         Bank.

10.      The Bank covenants that it shall not sell, transfer, assign,
         participate or otherwise dispose of any of its rights under the
         Indebtedness, the Security or the Letter of Credit without first
         providing Analogic with not less than ten (10) Business Days
         written notice in accordance with the terms of this agreement of
         its intention to do so. In the event the Bank does not receive a
         Call Notice from Analogic prior to the expiry of such ten (10)
         Business Day period, the Bank may sell, transfer, assign,
         participate or otherwise dispose of such interests without
         restriction; provided that any person to whom the Bank sells,
         transfers, assigns, participates or otherwise disposes of such
         interest shall have executed and delivered in favour of Analogic
         an agreement to be bound by the terms hereof.

11.      All amounts owing by the Company to the Bank under the Credit
         Facilities are payable on demand. Nothing in this Agreement shall
         be construed to limit the Bank's ability to demand repayment of
         the Indebtedness or to terminate the Credit Facilities in
         accordance with the terms of the Commitment Letter at any time
         without prior notice to any party, including Analogic, provided,
         however, that if a Demand has been made by the Bank, the Bank
         agrees that it shall not demand payment of the Indebtedness until
         the expiry of two Business Days following such Demand if during
         such two Business Day period no funds have been paid to the Bank
         under the Letter of Credit.

12.      Nothing contained in this Agreement is intended to or shall impair
         the obligations of the Company to repay the Indebtedness to the
         Bank (or to Analogic following the assignment of the Indebtedness
         and Security to Analogic in accordance with the terms of this
         Agreement) as and when such Indebtedness shall become due and
         payable in accordance with its terms nor shall anything herein
         prevent the Bank or Analogic, as the case may be, from exercising
         all remedies provided to the Bank or to Analogic under the
         Security or as otherwise permitted by applicable law. Upon
         repayment of the Indebtedness by the Company to the Bank and
         termination of the Credit Facilities, this Agreement shall be
         deemed to be of no further force and effect, in which case the
         Bank shall return the Letter of Credit to Analogic.

13.      The amount of the Indebtedness shall be determined, at all times,
         solely by reference to the Bank's records. Such records shall
         stand as conclusive evidence of the amount of the Indebtedness.

14.      In the event that on or prior to the time of closing on the L/C
         Closing Date or the Call Right Closing Date, as applicable (each,
         the "Closing Time"), notice in writing has been given to the Bank
         by a party entitled to redeem the Security or the Indebtedness
         that it intends to do so, the Bank shall notify Analogic of such
         notice, and the assignment of the Indebtedness and the Security
         shall be completed on the terms described herein subject to any
         rights of the party which has given the foregoing notice.

15.      In the event that on or prior to the Closing Time either the
         Indebtedness or the Security has been partially or fully redeemed
         or permanently repaid following enforcement of the Security, the
         parties agree as follows:

         (a)   in the case of a partial redemption of the Security or the
               Indebtedness, the Bank shall apply the funds paid to the
               Bank under such partial redemption in reduction of the
               Indebtedness, and the assignment of the Indebtedness and the
               Security shall be completed in accordance with the
               provisions hereof, subject to any rights of the party which
               has partially redeemed the Indebtedness or the Security; and

         (b)   in the case of permanent repayment of the Indebtedness
               through enforcement of the Security or a complete redemption
               of the Indebtedness or the Security such that no
               Indebtedness remains outstanding as at the Closing Time,
               Analogic shall not be required to pay the Purchase Price to
               the Bank and the Bank shall forthwith return to Analogic the
               Letter of Credit and any funds paid to or received by the
               Bank on account of the Purchase Price.

16.     (a)    In the event that on or before the Closing Time a
               proceeding (a "Proceeding") has been commenced before or a
               final or interlocutory order (an "Order") has been issued by
               a court of competent jurisdiction, seeking to order or
               ordering that the assignment of the Indebtedness and the
               Security contemplated by this Agreement be delayed or
               otherwise not completed in accordance with the terms of this
               Agreement, the parties agree to extend the Closing Time
               until such time as any such Proceeding has been discontinued
               or withdrawn and no final order of a court of competent
               jurisdiction exists prohibiting the parties from carrying
               out the terms of this Agreement. Analogic acknowledges and
               agrees that if the Closing Time is extended as aforesaid,
               the Purchase Price shall be equal to the amount of the
               Indebtedness outstanding as at the Closing Time, as such may
               be extended in accordance with this provision, and shall
               include all accrued interest and costs incurred by the Bank
               as at that date.

         (b)   Notwithstanding paragraph (a) of this section 16, unless the
               Proceeding or the Order seeks to order or actually orders
               that the Bank may not make a Demand or receive payment under
               the Letter of Credit, nothing shall prevent the Bank from
               making a Demand or receiving payment under the Letter of
               Credit or applying such funds in reduction of the
               Indebtedness, subject to the right of Analogic to obtain the
               assignment of the Indebtedness and the Security at the
               Closing Time, as such may be extended in accordance with
               this provision. In the event that the Closing Time is
               extended in accordance with this provision, the Bank will
               hold the rights of Analogic in the Indebtedness and the
               Security in trust for Analogic.

17.      The Indebtedness may consist of amounts contingently owing to
         third parties pursuant to a letter or letters of credit or
         guarantee issued by the Bank on behalf of the Company in
         accordance with the terms of the Credit Facilities (individually a
         "Bank L/C"). The amount of any such Bank L/C shall be included in
         the Bank's calculation of the Indebtedness, even if such Bank L/C
         has not yet been drawn upon by the beneficiary thereof. If, as at
         the Closing Date, any Bank L/C remains outstanding and has not yet
         been drawn upon, the Bank shall hold in a separate interest
         bearing account that part of the Purchase Price equal to the
         Bank's liability under the Bank L/C. Following the Closing Date,
         if a Bank L/C expires or is returned to the Bank prior to payment
         being made by the Bank thereunder, the Bank shall return to
         Analogic that part of the Purchase Price attributable to the Bank
         L/C together with any interest accrued thereon.

18.      Analogic acknowledges and agrees that the Credit Facilities shall
         be made available to the Company in accordance with the terms of
         the Commitment Letter without regard to the margin formula or any
         of the other conditions contained in the Original Commitment
         Letter. Analogic acknowledges and agrees in favour of the Bank
         that it shall make no claim against the Bank arising from the
         Bank's refusal or failure to monitor or enforce any of the
         covenants, the margin formula or any other term of the Original
         Commitment Letter. Analogic acknowledges in favour of the Bank
         that notwithstanding the Bank has made the Credit Facilities
         available to the Company pursuant to the Commitment Letter, the
         priority agreement between the Bank, 1144938 Ontario Inc. and the
         Company dated February 8, 2001, as the same may be amended from
         time to time, shall govern the priority of the Security and
         Indebtedness following any sale of the Indebtedness and Security
         to Analogic under the terms of this agreement.

19.      Subject to applicable laws, the Bank shall not without the prior
         written consent of Analogic: (i) amend the sections of the
         Commitment Letter entitled "Amount", "Interest Rate", "Demand
         Nature of the Facilities", or "Security"; (ii) consent to the
         undertaking by the Company of any of the transactions or
         operations listed under the section of the Commitment Letter
         entitled "Negative Covenants"; or (iii) amend the Security or
         grant any release or discharge or otherwise compromise its
         interest therein. Notwithstanding the foregoing, nothing contained
         herein shall be construed as limiting the Bank's ability to make
         any and all filings and registrations necessary or desirable in
         order to preserve or maintain its interest in the Security.

20.      From time to time upon request therefor, the Bank and Analogic may
         advise each other of and exchange any information or documentation
         which they may have relating to the affairs of the Company,
         including without limitation, the Credit Facilities, the Company's
         business and financial affairs, the particulars of the
         Indebtedness and the Security and the liability of the Company to
         the Bank and Analogic. The Company hereby consents to any such
         exchange of information.

21.      This Agreement shall be construed and interpreted in accordance
         with the laws of the Province of Ontario and the parties hereto
         irrevocably submit to the jurisdiction of the Superior Court of
         Justice (Ontario).

22.      The parties hereto agree that this Agreement shall enure to the
         benefit of and binding upon, the parties hereto and their
         respective heirs, executors, administrators, successors and
         permitted assigns.

23.      This Agreement may be executed manually, or by facsimile signature
         by the parties hereto and may be executed in separate
         counterparts, each of which when so executed and delivered shall
         be an original, and such counterparts shall together constitute
         one and the same instrument. To the extent that this Agreement is
         executed by facsimile signature, the parties who are executing it
         shall forthwith deliver to the other parties manually executed
         copies thereof.

         to the following address, as applicable, and shall be deemed to
         have been received on the earlier of actual receipt of such notice
