          consignment and will remain at all times under
          and subject to the ownership, direction and
          control of IMMU until sold through  MM or its
          Sub-Consignees to the ultimate customers.  Title
          to the Product held by MM on consignment will
          pass directly from IMMU to the customers who
          purchase the Product through MM or its Sub-Consignees. 
          Title to the technetium-99m ("Tc-99m") 
          incorporated by MM in the preparation of
          the Finished Product shall pass from MM to IMMU
          at the time of such incorporation.  IMMU shall
          bear the risk of loss of the Product not yet
          delivered by MM to a customer, whether by fire,
          theft, or other casualty; provided, however,
          that MM shall reimburse IMMU    *    per vial
          for any Product which is lost or damaged as a
          result of MM's negligence including, but not
          limited to failure to perform the Tc-99m
          labeling properly or delayed delivery of the
          Product.  IMMU is hereby granted a security
          interest in the consigned stock held by MM and
          in all proceeds from sales made therefrom,
          including accounts receivable and cash receipts. 
          MM shall execute and deliver to IMMU such
          instruments as IMMU shall require, including UCC
          financing statements, to enable IMMU to perfect
          such security interest.  Attached as Schedule C
          is a list of MM warehouses or other storage
          locations at which MM will maintain supplies of
          the Product; during the term of this Agreement,
          MM shall notify IMMU promptly of any changes or
          additions to the locations at which supplies of
          the Product will be maintained, including
          without limitation locations of Sub-Consignees.

2.03      Appointment of Sub-Consignee.  In order to
          maximize distribution of the Product, MM shall
          have the right to engage, and MM shall use its
          best efforts to engage, other entities,
          including without limitation 
          *         and        *,
          Inc.    *, as Sub-Consignees and
          distributing agents, sharing with such 
          Sub-Consignees such portions of the fees
<PAGE>
          payable to MM by IMMU hereunder as MM and such
          Sub-Consignees shall in good faith negotiate.
          IMMU shall not participate in such negotiations. 
          However, in the event that MM does not reach
          agreement on the engagement as a Sub-Consignee
          of    *    or    *    within   *   months of the
          Effective Date, or of another third-party
          radiopharmacy company deemed by IMMU to be
          material to the successful distribution of the Product 
          within   *    months of IMMU having notified MM of its
          judgment that such radiopharmacy company is so
          material, then IMMU shall have the right to
          enter into a separate consignment agreement with
          such company or companies.

          In all agreements with Sub-Consignees, MM shall
          require the Sub-Consignees to carry out the same
          obligations as MM would be required under the
          terms of this Agreement to carry out with regard
          to the Product delivered on consignment to such
          Sub-Consignee, including without limitation the
          obligations to adhere to the same standards of
          sales conduct, to effect sales only on the basis
          of IMMU's approved credit terms, to refrain from
          selling other than on a C.O.D. basis to
          customers placed on a restricted list by IMMU,
          and to provide information regarding sales and
          inventory.  MM shall be responsible to IMMU for
          the conduct of its Sub-Consignees and for the
          enforcement of its agreements with its Sub-Consignees.

2.04      Reservation of Rights.  IMMU reserves to itself
          and its Affiliates the right to market and sell
          the Product independent of MM and its Sub-Consignees 
          directly to hospital nuclear medicine
          departments in the Territory and to contract
          independently for a specialty oncology sales
          force to market the Product at IMMU's expense,
          and, subject to IMMU's existing License
          Agreement, dated March 10, 1995, with MM's
          Affiliate, Mallinckrodt Medical, B.V., to
          manufacture, market and sell the Product
          independent of MM in and for countries located
          outside the Territory, including without
          limitation, the right to appoint other Persons
          as marketing representatives, dealers,
          distributors and manufacturers for sale of the
          Product outside the Territory.

       ACCEPTANCE; MARKETING OBLIGATIONS
                        
                        
3.01      Acceptance. MM shall use its best efforts
          consistent with accepted business practices in
          the marketing of nuclear imaging products and
          legal requirements to launch, detail, promote,
          advertise, distribute and sell the Product  for
          use in colorectal cancer diagnostic imaging in
          the Territory during the term of this Agreement
          exercising the same diligence and adhering to
          the same standards as MM would adopt in launching,
          detailing, promoting, advertising, distributing
<PAGE>
          and selling a major nuclear medicine
          or pharmaceutical product of its own
          innovation, with the objective to make the
          Product the market leader in its field of
          intended use.  Pursuant to this undertaking, MM
          shall direct its nuclear medicine sales force,
          as well as a specialty sales force, to educate
          the nuclear medicine and oncology communities
          regarding the Product and to actively promote
          the sale of the Product to such communities.
          During the first     *     following the
          Effective Date, MM shall retain a nuclear
          medicine sales force of at least   *
          representatives, as well as a specialty sales
          force of at least   *   representatives whose
          focus is oncologists.  Upon receipt by IMMU of
          a Product License ("PL") from the FDA with
          respect to the Product, MM shall cause such
          oncology sales force to be expanded to at least
           *    representatives.  At any time after the
             *          of the launch of the Product,
          MM shall have the right to reduce the size of
          its nuclear medicine sales force, generally, or
          its specialty oncology sales force, provided
          that IMMU shall have the right to terminate the
          Agreement if such reduction exceeds  *  of the
          aggregate number of individuals contemplated by
          this Section 3.01.

3.02      Promotion Standard. In launching, detailing,
          promoting, advertising, distributing and selling
          the Product, MM shall maintain and adhere
          strictly to the diagnostic claims of the Product
          as established by IMMU and approved by the FDA.
          All promotional materials prepared through MM
          and all promotional activities relating to the
          Product sold through MM shall comply with all
          applicable state and federal laws and FDA rules
          and regulations.

3.03      MM's Authority/Responsibility. During the term
          of this Agreement, except as otherwise expressly
          herein provided, MM shall have the
          responsibility to take such actions with respect
          to the Product as would normally be done in
          accordance with accepted business practices in
          the marketing of nuclear imaging products to
          actively market the Product within the
          Territory, including, without limitation, the
          following:

               (i)  responding to product and medical
                    complaints relating to the Product. 
                    As called for by Section 8.01
                    hereof, each party shall promptly
                    advise the other of any such
                    complaints which it receives from
                    regulators, customers or patients in
                    the Territory;

               (ii) providing IMMU with shipping
                    information as to MM's own sales on
                    a daily basis and as to sales by
                    Sub-Consignees as promptly as
                    possible but no less frequently that
                    once a month; and invoicing the
                    customer on an IMMU invoice on the
                    same invoicing cycle as MM or its
                    Sub-Consignees utilizes with their
                    other products;
<PAGE>               
               (iii)  handling all returns of the Product. 
                    Should the Product be returned
                    directly to IMMU, IMMU shall
                    promptly advise MM of such return. 
                    IMMU shall, in it sole discretion,
                    decide whether to accept the return. 
                    The parties will share the cost of
                    the return as a reduction of Gross
                    Sales;

               (iv) handling, in accordance with Section
                    8.02 hereof, all recalls of the
                    Product;

               (v)  handling Product distribution,
                    shipping, inventory tracking and lot
                    tracing; 

               (vi) preparing technetium-99m-labeled
                    unit doses of the Product and
                    quality control testing to assure
                    the safety and efficacy of the
                    Product; and
               
               (vii)  packaging of Product in dosage units
                    for cold kit (non unit dose) orders.

3.04      Restricted List.  IMMU and MM, through its
          Coordinators or otherwise, shall in good faith
          cooperate to establish and regularly update a
          list of customers whose credit ratings and
          experience are unacceptable to IMMU (the
          "Restricted List").  Sales of the Product
          through MM or its Sub-Consignees to customers
          appearing on such Restricted List shall be made
          only on a C.O.D. basis.  In the event MM or a
          Sub-Consignee sells Product to a customer on the
          Restricted List other than on a C.O.D. basis, MM
          or such Sub-Consignee shall bear the risk of
          non-payment by that customer and shall be liable
          to IMMU for the amount owed by the customer but
          not paid to IMMU, including interest at the rate
          generally charged to customers by IMMU.  In such
          event, IMMU shall give notice to MM of such non-payment 
          no later than 90 days after the initial
          bill is mailed to the unapproved customer.  MM
          shall pay, or cause its Sub-Consignee to pay, to
          IMMU within 120 days from the date on which the
          initial bill was mailed to the unapproved
          customer the full amount owed by the unapproved
          customer on that date, including interest at the
          rate generally charged to customers by IMMU.

3.05      Sales for Export.  MM shall not export the
          Product from the Territory and shall use
          reasonable diligence to ensure that Product sold
          through MM on a consignment basis is not sold
          with a view to export from the Territory. 
          Correspondingly, IMMU shall use reasonable
          diligence to ensure that Product sold outside
          the Territory is not sold with a view to export
          into the Territory.

3.06      Non Compete.  During the term of this Agreement
          MM shall not launch, detail, promote, advertise,
          distribute or sell in the Territory a monoclonal antibody
<PAGE>
          based in-vivo  diagnostic imaging
          product which competes with the Product for
          colorectal cancer indications.

3.07      Minimum Marketing and Selling Efforts. Without
          limiting its obligations under Section 3.01
          above, in each of the first two Contract Years
          of the term of this Agreement, MM shall at a
          minimum expend with third parties, in accordance
          with standard cost accounting, the amounts
          specified in Schedule B for promotion, marketing
          and selling activities exclusively relating to
          the Product, training relating exclusively to
          the Product, and other miscellaneous efforts
          relating exclusively to the distribution and
          sale of the Product in the territory. By notice
          given to MM not later than January 1, 1998, IMMU
          shall have the right to direct MM to make an
          additional     *     of such expenditures in
          the Contract Year commencing in 1998.  With
          respect to each Contract Year commencing after
          1998, IMMU shall have the right to request that

          MM make an additional     *    of such
          expenditures, but MM shall have no obligation to
          agree to such request.  IMMU shall make any such
          request by notice given to MM not later than
          January 1 of the year prior to that to which the
          request relates, and MM shall notify IMMU as to
          whether or not it agrees to be bound to make
          such an additional expenditure within thirty
          (30) days of the delivery to MM of IMMU's
          request.  

          MM shall deliver to IMMU a certificate within
          forty-five (45) days after each Contract Year
          during the term of this Agreement setting forth
          in reasonable detail the actual amounts actually
          expended by MM for promotion, marketing,
          selling, training, and other miscellaneous
          expenditures relating to the Product during such
          period.

3.08      PL Fee.  Upon issuance by the FDA of a PL for
          the Product, in partial consideration for the
          rights granted to MM hereunder, MM shall pay to
          IMMU a one-time, non-refundable, non-creditable
          fee of   *.

             PRODUCT REGISTRATIONS


4.01      Registration Activities.  IMMU shall use all
          reasonable diligence in pursuing the processing
          of its existing filing with the FDA to obtain a
          PL for use of the Product as an in vivo 
          colorectal cancer diagnostic imaging agent. 
          Through its Coordinator, IMMU shall keep MM
          fully apprised of the status of its registration
          efforts with respect to the Product with the
          FDA.
<PAGE>
4.02      Regulatory Changes. Each party shall promptly
          advise the other party of any known new
          instructions or specifications relating to the
          Product required by the FDA and other applicable
          authorities, and the parties shall confer with
          respect to the best mode of compliance with such
          new requirements.  Compliance with such new
          requirements shall be  the sole responsibility
          of IMMU.


                   ARTICLE 5 
                        
       COORDINATORS  AND MARKETING PLANS


5.01      Coordinators. The parties shall each appoint one
          individual (a "Coordinator") who shall be the
          principal representative of such party with
          respect to all matters arising under this
          Agreement and who shall be responsible to
          coordinate communications from the other party
          to and within his or her respective
          organization.  Each party will notify the other
          as to the name of the individual so appointed. 
          Each party may replace its Coordinator at any
          time, upon notice to the other party. The
          Coordinators will confer in person at IMMU's
          offices or at another location agreeable to
          IMMU, from time to time, but no less than
          quarterly to discuss and to coordinate the
          effective performance of the terms of this
          Agreement. Among their other functions, the
          Coordinators shall exchange such information
          (other than information obtained under an
          obligation of confidentiality from a third
          party) as either party has obtained relevant to
          the marketing and selling of the Product as may
          be useful to the other party in its marketing
          efforts.

5.02      Marketing Plans; Sales Forecasts.  Within thirty
          (30) days after the Effective Date, and
          thereafter no later than March 1 of each fiscal
          year of MM occurring during the term of this
          Agreement, MM shall present its preliminary
          marketing plan for the forthcoming fiscal year
          (July 1 to June 30), including planned pre-launch 
          and launch activities, detailing
          promotion and marketing strategies relating to
          the Product in the Territory and estimates of
          the costs and expenses to implement such
          preliminary marketing plan. Such preliminary
          marketing plan shall also include sales
          forecasts with respect to the Territory for such
          forthcoming fiscal year.  The Coordinators shall
          review and discuss such preliminary marketing
          plan and sales forecasts at a meeting convened
          within thirty (30) days after delivery of such
          plan and forecasts, and MM shall in good faith
          take into account changes to such preliminary
          marketing plan recommended by the Coordinator
          representing IMMU.  Based upon such review and
          recommendations, within thirty (30) days after
          such Coordinators' meeting and in any event no
          later than June 1 of each year during the term
          of this Agreement, MM shall deliver to IMMU its
          final marketing plan for the forthcoming fiscal
          year (each an "Annual Marketing Plan").  IMMU
          hereby acknowledges that any such Annual
          Marketing Plan only represents MM's best
<PAGE>
          estimate of its plans and performance for the
          forthcoming fiscal year and does not represent
          any performance guarantee on the part of MM.  At
          each subsequent meeting of the Coordinators, MM
          shall present a report of its fulfillment of the
          objectives of the then-current Annual Marketing
          Plan.

5.03      IMMU Marketing Rights.  IMMU shall have the
          right, in its sole discretion, to supplement
          MM's marketing and selling effort with respect
          to the promotion of the Product in the Territory
          by making its own marketing and promotional
          expenditures (including Phase IV trials) of up
          to    *     in any Contract Year.  Prior to
          any exercise of such right, IMMU shall give
          notice thereof to MM through communication
          between the Coordinators, and such notice shall
          specify in reasonable detail the activities
          which IMMU intends to undertake. IMMU shall
          deliver to MM a certificate on a quarterly basis
          setting forth in reasonable detail the amounts
          actually expended or incurred. If during either
          of the two successive Contract Years following
          the expenditure by IMMU of amounts in respect of
          such supplemental marketing, actual sales of
          unit doses exceed forecasted sales of unit doses
          as set forth in Schedule A hereto, IMMU shall be
          entitled to recover the cost of such marketing
          effort by reducing the fees which would
          otherwise be payable to MM as follows:

          a)   IMMU shall prepare a certificate setting
               forth the amount by which sales of unit
               doses during the applicable period
               exceeded the forecasted sales of unit
               doses as set forth in Schedule A hereto
               (the "Incremental Sales), as well as the
               calculations described in (b) below (the
               "Incremental Sales Certificate");  
          
          b)   In lieu of the fees contemplated by
               Section 7.03 hereof that would otherwise
               be payable in respect of such Incremental
               Sales,  IMMU shall pay MM a fee  of:
          
                     *   per unit dose of Product,
                    whether labeled or sold as a cold
                    kit, if such Incremental Sales were
                    made during the period specified in
                    Section 7.03(a), or $*   per
                    labeled unit dose of Product or
                    $*    per cold kit, if such
                    Incremental Sales were made during
                    any other period.
               
               Such payment terms shall remain in effect
               as to Incremental Sales until such time as
               the difference between (x) the amounts
               that would have been payable to MM in
               respect of such Incremental Sales under
               Section 7.03 but for the operation of this
               Section 5.03 and (y) the amounts actually
               paid to MM under this Section 5.03 equals
               the amount expended by IMMU for its
               marketing and selling efforts described in
               this Section 5.03.  Once such amount has
               been fully recovered by IMMU, the
               provisions of Section 7.03 shall apply to
               the remaining Incremental Sales.
<PAGE>

          c)   From and after the delivery of the
               Incremental Sales Certificate, MM shall
               promptly refund to IMMU any fees already
               received by MM in respect of the
               Incremental Sales which exceed the amounts
               otherwise due to MM under the provisions
               of this Section 5.03 or, failing which,
               IMMU shall have the right to set off such
               amounts against future fees owed to MM.

5.04      Sampling. To achieve the objectives of this
          Agreement, both parties recognize that,  to the
          extent allowable by law, it may be necessary to
          distribute a nominal quantity of the Product
          free of charge as samples to health care
          personnel and members of the trade on an ongoing
          basis ("Sampling Program").  For any such
          Sampling Program, the Coordinators, from time to
          time, shall establish a reasonable sampling
          strategy, setting forth a sampling period, the
          number of samples to be distributed during such
          sampling period and the schedule for delivery of
          samples.

6.01      Exclusive Supply; Requirements.  IMMU will
          deliver on consignment  to MM, and MM will
          accept delivery from IMMU of all of MM's
          requirements of the Product for sale in the
          Territory.  MM shall order and accept delivery
          of  such amounts and maintain such inventory of
          the Product as shall enable it to make prompt
          and timely delivery of the Product to customers
          in the Territory.

6.02      IMMU's Supply Efforts.  IMMU shall use its best
          efforts to manufacture or otherwise supply
          sufficient quantities of the Bulk Vialed Product
          to MM for all commercial purposes in the
          Territory.

6.03      Finished Dose Packaging.  MM will, at its own
          expense, label and package the Finished Product
          (including the preparation and insertion of
          appropriate package inserts) for distribution
          and sale in the Territory.  All such packaging,
          labeling and package insert materials prepared
          by MM shall comply with all applicable laws,
          regulations and guidelines of the FDA.  MM shall
          bear any and all costs and expenses associated
          with labeling changes required by state or
          federal law or FDA rules or regulations.

6.04      Delivery Forecasts.  MM shall provide IMMU at
          least three (3) months before the beginning of
          each fiscal year with a forecast of MM's total
          requirements for the Product in the upcoming
          fiscal year, which forecast shall be updated
<PAGE>
          quarterly.  In the case of the first fiscal year
          commencing after the Effective Date, such
          forecast shall set forth the requirements for
          the period between the anticipated date of first
          commercial sale to a third party and the end of
          such fiscal year. MM shall use its best efforts
          to make all forecasts and estimates required
          hereunder to be reasonably accurate predictions
          of the amount of Product MM will actually
          require for the Territory for the relevant
          period.

6.05      Transportation Terms.  All orders for the
          Product submitted by MM to IMMU hereunder shall
          be delivered by IMMU to the MM warehouses or
          distribution centers specified by MM.  All
          costs, taxes, insurance premiums and other
          expenses relating to the transportation and
          delivery of the Product shall be at IMMU's
          expense.  Risk of loss of, and damage to, any
          shipment shall remain with IMMU, and title shall
          at all times remain vested in IMMU.

6.06      Conflicting Terms.  This Agreement sets forth
          the entire understanding between the parties
          relating to the subject matter hereof and shall
          govern all transactions between the parties
          contemplated hereby.  Except for terms relating
          only to quantities, ship dates and delivery
          destinations, none of the terms and conditions
          contained on any purchase order, invoice or
          similar document shall have any effect upon or
          change the provisions of this Agreement unless
          signed by both parties and clearly indicating
          that the parties intend to vary the terms
          hereof.

            PRODUCT PRICING; PAYMENT
                        

7.01      Sale Price.  IMMU shall provide to MM no later
          than 90 days following receipt from the FDA of
          the PL for the Product a schedule setting forth
          the price at which it will sell the Product to
          customers.  Such price may be changed by IMMU at
          any time upon thirty (30) days' advance notice
          to MM.

7.02      Invoicing.  Upon delivery of the Product to a
          customer, MM shall supply that customer with an
          IMMU invoice indicating that the amount due for
          the Product is to be paid directly to IMMU.  At
          least once each week, MM shall deliver to IMMU
          a complete list of customers to whom it has sold
          Product during the immediately preceding week. 
          Such list shall include all information
          necessary to enable IMMU to maintain accounts
          receivable and cash receipts for such customers
          for the Product delivered, including but not
          limited to such information as each serviced
          customer's name, address, and telephone number,
          the quantity sold to each such customer, the
          date the order was placed by each customer, the
          date the Product was delivered to each customer,
          the address to which the Product was delivered
          to each customer, and the name of a contact
<PAGE>
          person at the business of each customer.  IMMU
          shall be responsible for collecting the billing

          shall be the owner of, and bear the credit risk
          on, all accounts receivable arising from the
          sales of the Product, except as specified in
          Section 3.04 hereof.

7.03      Payment.  IMMU shall pay MM a quarterly fee
          based upon the Net Sales of the Product effected
          through MM on a consignment basis as follows:

          (a)  For sales of Product while MM is actively
          engaged in the marketing, promotion, sales and
          distribution of the Product:

               (i)  During the first twelve months after
               product launch,  *% of such Net Sales or
               $*   per labeled unit dose of the
               Product, whichever is greater;

               (ii) Thereafter, for so long as MM
               expends at least $*     per Contract
               Year on marketing and promotion of the
               Product,  *% of such Net Sales or $*
               per labeled unit dose of the Product,
               whichever is greater; and

               (iii)     For cold kits, $*   per kit.

          (b)  For sales of Product while MM is not
          actively engaged in the marketing and promotion
          of the Product (i.e., for Contract Years in
          which MM expends less than $*      on such
          activities):

               (i)  During the first Contract Year in
               which MM no longer performs such
               functions, $*    per labeled unit dose of
               the Product;

               (ii) During each subsequent Contract
               Year, $*     per labeled unit dose of the
               Product;
               
          with such amount to be adjusted for increases in
          the Consumer Price Index, as well as increases
          in technetium prices above $*      per dose;
          provided that in no event shall the unit dose
          fee exceed $*.
               
               (iii)     For cold kits, $*   per kit.
               

7.04      Currency. All payments between the parties under
          this Agreement shall be made in U.S. Dollars
          and, except as otherwise expressly provided, all

          be deemed to mean and refer to U.S. Dollars.

               COMPLAINTS/RECALLS


8.01      Complaints. To the extent that it has knowledge
          thereof, each party shall promptly notify the
          other in writing of any defect in, or condition
          of, the Product which may cause the Product to
          violate the U.S. Federal Food, Drug and Cosmetic
          Act or Section 352 of the U.S. Public Health
          Service Act or any material regulations
          promulgated thereunder, or similar applicable
          state and federal laws and FDA rules and
          regulations.  IMMU and MM shall share with each
          other all data on complaints respecting the
          Product, including, but not limited to,
          complaints or information regarding performance
          or allegations or reports of any effects on a
          patient from use of such Product, as soon as
          such data is available.

8.02      Recall. In the event that either party has
          reason to believe that one or more lots of
          Product should be recalled or withdrawn from
          distribution, such party shall immediately
          notify the other party in writing.  To the
          extent permitted by the circumstances, the
          parties, through their respective Coordinators,
          will confer before initiating any recall, but
          the decision as to whether or not to initiate a
          recall of Product in the Territory shall be
          IMMU's alone. MM shall maintain adequate sales
          and service records to enable it to carry out
          any Product recall and to conduct such recall. 
          If the recall is required because of a
          modification of the registrations, permits or
          licenses for the Product or a failure of the
          Product to conform to its specifications as
          provided to the FDA, IMMU shall reimburse MM for
          the costs and expenses of such recall and shall
          replace such recalled Product.  If the recall is
          required because of a negligent act or omission
          of MM in handling, storage or distribution of
          the Product, then such recall shall be conducted
          by MM at its sole cost and expense and MM shall
          not be entitled to any such refunds or
          replacements from IMMU.  If such recall is
          required because of a joint act or omission,  MM
          shall conduct the recall and the parties shall
          negotiate in good faith an appropriate
          allocation of the costs and expense of such
          recall.

8.03      Regulatory Records; Adverse Reactions. Each
          party shall be responsible for maintaining such
          records and making such reports as may be
          required by the FDA in connection with the PL
          relating to the Product.  Each party shall
          promptly inform the other of all adverse drug
          experience reports and other information
          relating to the safety or effectiveness of the
          Product which come to its attention, in a form
          and within time periods necessary to permit
          compliance with all applicable regulatory
          requirements under FDA rules and regulations.

          mark(s) as IMMU shall cause to be registered for
          the Product (collectively the "Marks") in the
          Territory in connection with, and confined to
          the purpose of, the sale, marketing and
          distribution of the Product.  MM shall use the
          Marks on labeling, packaging and package inserts
          for the Product, in all of MM's promotion of the
          Product and in all literature related thereto,
          and MM shall not use any other trademarks or
          logos on any labeling,  packaging, package
          inserts, literature or promotional material
          relating to the Product.  MM shall comply with
          and observe the reasonable requirements of IMMU
          relating to (i) the marking of the Product
          and/or its label, packaging, package insert or
          other printed materials pursuant to any and all
          applicable patent laws to indicate that letters
          patent have been applied for or granted in one
          or more countries and (ii) the use of the Marks
          in conformity with the trademark laws of the
          Territory.  Prior to its use, MM shall submit
          all such labeling, packaging, package inserts,
          promotional material and related literature to
          IMMU for its approval of the use of such Marks,
          which approval shall not be unreasonably
          withheld by IMMU.

9.02      Ownership of Marks.  MM acknowledges that the
          Marks are and shall remain the property of IMMU,
          and MM disclaims any rights to such Marks other
          than the rights granted by Section 9.01 hereof. 
          MM shall not use the Marks or any other IMMU
          trademark, trade or brand name for any purpose
          other than as provided in such Section 9.01.

          injury, damage, death or other consequence
          occurring to any person is specifically and
          proximately due to a breach by IMMU of the

          10.03 and 10.04, give such Indemnifying
          Party written notice of such claim or the
          commencement of such action or proceeding and
          shall permit the Indemnifying Party to assume
          the defense of any such claim or any litigation
          resulting from such claim, and, upon such
          assumption, shall cooperate fully with the
          Indemnifying Party in the conduct of such
          defense.  Failure by the Indemnifying Party to
          notify the Aggrieved Party of its election to
          defend any such action within a reasonable time,
          but in no event more than fifteen days after
          notice thereof shall have been given to the
          Indemnifying Party, shall be deemed a waiver by
          the Indemnifying Party of its right to defend
          such action.

          (b)  If the Indemnifying Party assumes the
          defense of any such claim or litigation
          resulting therefrom, the obligations of the
          Indemnifying Party as to such claim shall be
          limited to taking all steps necessary in the
          defense or settlement of such claim or
          litigation resulting therefrom and to holding
          the Aggrieved Party harmless from and against
          any and all losses, damages and liabilities
          caused by or arising out of any settlement
          approved by the Indemnifying Party or any
          judgment in connection with such claim or
          litigation resulting therefrom. The Aggrieved
          Party may participate, at its expense, in the
          defense of such claim or litigation, provided
          that the Indemnifying Party shall direct and
          control the defense of such claim or litigation. 
          The Indemnifying Party shall not, in the defense
          of such claim or any litigation resulting
          therefrom, consent to entry of any judgment,
          except with the written consent of the Aggrieved
          Party, or enter into any settlement, except with
          the written consent of the Aggrieved Party,
          which does not include as an unconditional term
          thereof the giving by the claimant or the
          plaintiff to the Aggrieved Party of a release
          from all liability in respect of such claim or
          litigation.
          
          (c)  If the Indemnifying Party shall not assume
          the defense of any such claim or litigation
          resulting therefrom, the Aggrieved Party may
          defend against such claim or litigation in such
          manner as it may deem appropriate and, unless
          the Indemnifying Party shall deposit with the
          Aggrieved Party a sum equivalent to the total
          amount demanded in such claim or litigation, or
          shall deliver to the Aggrieved Party a surety
          bond in form and substance reasonably
          satisfactory to the Aggrieved Party, the
          Aggrieved Party may settle such claim or
          litigation on such terms as it may deem
          appropriate, and the Indemnifying Party shall
          promptly reimburse the Aggrieved Party for the
          amount of all reasonable expenses, legal or
          otherwise, incurred by the Aggrieved Party in
          connection with the defense against or
          settlement of such claims or litigation.  If no
          settlement of such claim or litigation is made,
          the Indemnifying Party shall promptly reimburse
          the Aggrieved Party for the amount of any
          judgment rendered with respect to such claim or
          in such litigation and of all reasonable
          expenses, legal or otherwise, incurred by the
          Aggrieved Party in the defense against such
          claim or litigation.

10.06     Insurance Coverage.  (a) Each party shall
          purchase and maintain insurance at its own
          expense to cover liabilities that it may incur
          in the testing, manufacture, distribution, sale
          or use of the Product.  Each party agrees to
          provide the minimum amounts and types of
          insurance, to protect its interests, as follows,
          which may include self insurance : 

          (I)  Commercial General Liability Insurance
               with the following minimum limits of
               liability:

               General Aggregate                       $ *
               Personal and Advertising Injury           *
               Each Occurrence                           *

          (ii) Insurance covering Product Liability in
               amounts not less than:

               General Aggregate                       $ *
               Each Occurrence                           *

          In the event that any such policies are on a
          claims-made basis, coverage shall be maintained
          for a period of at least five years after the
          termination of this Agreement. Each party shall
          furnish to the other certificates of insurance,
          evidencing such insurance and naming the other
          party as a co-insured, except for limits covered
          under the self-insurance programs of either
          party.

          (b)  MM shall, in addition, include IMMU as an
          additional named insured on its policies of
          product liability insurance covering the Product
          and on its general comprehensive liability
          insurance covering the sale and distribution of
          the Product in the Territory and shall cause
          such policies to provide that they shall not be
          canceled by the insurer without thirty (30)
          days' prior notice thereof to IMMU, and, upon
          IMMU's request, MM shall furnish IMMU with a
          certificate of insurance evidencing such
          coverage.

       PATENT AND TRADEMARK INFRINGEMENT


11.01     Patents.  IMMU warrants and represents that it
          has no knowledge of the existence of any patent
          in the Territory owned or controlled by anyone
          other than IMMU, which covers the Product or
          would prevent MM or IMMU from making, using or
          selling the Product in the Territory or would
          prevent MM and IMMU from promoting or
          distributing the Product in the Territory.
<PAGE>
11.02     Infringement of IMMU's Rights.  Each party shall
          promptly notify the other upon its becoming
          aware of any actual or suspected infringement by
          a third party of a patent or trademark owned by
          IMMU covering or identifying the Product in the
          Territory.  IMMU and MM shall confer on the
          desirability of initiating action against such
          third party and, if warranted in the reasonable
          opinion of IMMU, IMMU shall promptly take such
          action, including the initiation of legal
          proceedings, as is required to restrain or
          otherwise prevent such infringement.  IMMU shall
          have the right to retain any and all amounts
          recovered from such third party as a result of
          any action which it may bring.

11.03     Infringement of Third Party Rights.  In the
          event that a third party at any time provides
          written notice of a claim to, or brings an
          action, suit or proceeding against, either party
          or any of their respective Affiliates, claiming
          infringement of its patent or trademark rights
          or unauthorized use or misappropriation of its
          technology, based upon an assertion or claim
          arising out of the manufacture, use and/or sale
          of Product in the Territory, such party shall
          promptly notify the other party of the claim or
          the commencement of such action, suit or
          processing, enclosing a copy of the claims
          and/or all papers served.  Each party will make
          available to the other party its advice and
          counsel regarding the technical merits of any
          such claim. IMMU shall undertake, at its
          expense, the defense of any such action, suit or
          proceeding and shall manage and control the
          defense of such action and its settlement.  If
          as a result of any such action, suit or
          proceeding, IMMU, in order to sell the Product
          in the Territory, becomes obligated under an
          agreement or settlement, to make any payments to
          one or more parties to obtain a license or
          similar right in the absence of which the
          Product could not lawfully be made, used or sold
          in the Territory, then IMMU shall have the right
          to increase the selling price of the Product to
          compensate for such payments, effective on the
          date of imposition of such payments.

              TERM AND TERMINATION


12.01     Term.  This Agreement shall commence on the
          Effective Date and, except as provided below in
          this Article 12, shall extend until terminated
          by either party hereto by notice given to the
          other, provided, that:

               (a)  neither party shall deliver a notice
          of termination to the other party prior to the
          second anniversary of the Effective Date;

               (b)  no notice of termination given by
          IMMU shall be effective prior to the expiration
          of twelve (12) months following the later of (i)
          the date of such notice or (ii) the end of the
          Contract Year in which MM has made $1 million of
<PAGE>
          expenditures of the nature contemplated by
          Section 3.07 at IMMU's direction or upon IMMU's
          request; and

               (c)  no notice of termination given by MM
          shall be effective prior to the expiration of
          twenty four (24) months following the later of
          (i) the date of such notice or (ii) the end of
          the Contract Year in which MM has made $1
          million of expenditures of the nature
          contemplated by Section 3.07.

12.02     Mutual Termination Rights.  Either party shall
          have the right to terminate this Agreement:

               (a)  upon sixty (60) days' prior notice
          to the other in the event that the other shall
          commit any material breach of its obligations
          hereunder and shall fail to remedy the same
          within forty-five (45) days after being called
          upon in writing to do so; or

               (b)  to the extent permitted by law, upon
          notice to the other party, in the event the
          other party suspends its business, becomes
          insolvent, fails generally to pay its debts as
          they mature, files a voluntary petition or any
          answer admitting the material allegations of, or
          consents to, an involuntary petition pursuant to
          or purporting to be pursuant to any
          reorganization or insolvency law of any
          jurisdiction, makes an assignment for the
          benefit of creditors, or applies for or consents
          to the appointment of a receiver or trustee of
          a substantial part of its property; or

               (c)  upon notice to the other party
          following a "change of control" of the other
          party, if immediately following such change of
          control the Person or Persons acquiring control
          of such other party are competitors of the
          terminating party.  For purposes of this clause,
          a "competitor" means any Person whose product
          line includes an in vivo  diagnostic imaging
          agent for colorectal cancer indications,  and a
          "change of control" shall be deemed to have
          occurred with respect to a party to this
          Agreement if (i) a Person or group of Persons
          acting in concert acquires more than 50% of the
          voting power of all outstanding voting
          securities of such party, (ii) such party
          engages in a corporate transaction (including a
          merger, consolidation, sale of assets or other
          corporate reorganization) which upon its
          consummation results in the shareholders of such
          party immediately prior to such transaction
          owning less than 50% of the outstanding stock of
          the resulting entity, or (iii) as to MM, its
          ultimate corporate parent ceases to own,
          directly or indirectly, at least 50% of the
          outstanding common stock of MM or ceases to have
          the right to designate at least one half of the
          board of directors of MM.

12.03     Competitive Product.  In the event that MM or
          one of its Affiliates develops another in vivo 
          diagnostic imaging product for colorectal cancer
          indications which is not monoclonal based, MM
          shall notify IMMU, simultaneously with
<PAGE>
          its first submission of a product registration filing
          in the Territory, that such filing has been made.
          After the delivery of such notice, MM shall have
          the right to elect to terminate this Agreement
          upon twelve (12) months' prior notice, and IMMU
          shall have the right to elect to terminate this
          Agreement upon one (1) month prior notice.

12.04     Market Diligence.  Without limiting its right to
          termination for material breach as contemplated
          by Section 12.02, IMMU shall have the right to
          terminate this Agreement upon sixty (60) days'
          prior notice to MM if: (i) MM's projected unit
          sales of the Product as set forth in Schedule A
          hereto for the calendar year 1997 is not
          achieved in such year;  or (ii) MM has
          materially failed to fulfill the objectives of
          its Annual Marketing Plan for two successive
          annual periods.

12.05     Lack of Product Registration.  Without limiting
          its right to termination for material breach as
          contemplated by Section 12.02, MM shall have the
          right to terminate this Agreement upon sixty
          (60) days' prior notice to IMMU given at any
          time between July 1, 1997 and August 31, 1997,
          if by June 30, 1997, IMMU shall not have
          obtained a product registration for the
          marketing of the Product in the Territory.

12.06     Reduction in Sales Force.  IMMU shall have the
          right to terminate this Agreement upon sixty
          (60) days' prior notice to MM given at any time
          after MM shall have reduced its sales force
          below the minimum numbers of representatives
          specified in Section 3.01.

12.07     Rights and Obligations Upon Termination. (a) 
          Upon any termination of this Agreement, MM shall
          promptly return to IMMU or its designee or
          otherwise cause to be transferred to IMMU all
          Confidential Information of IMMU, and MM shall
          have no further rights thereto.  MM shall not,
          after the termination of this Agreement, use in
          the Territory any name or mark confusingly
          similar to any Mark of IMMU's in connection with
          the sale of any product through MM.

          (b)  Termination of this Agreement in whole or
          in part shall not relieve the parties of any
          amounts owing between them, nor shall it relieve
          the parties of their obligations with respect to
          the Product distributed hereunder, or with
          respect to limiting disclosure and use of
          Confidential Information.  Upon termination of
          this Agreement, IMMU shall have the right to re-take 
          possession of all of the inventory of
          Product then held by MM at any of its locations. 
          The provisions of Article 10 and 13 shall
          survive any termination of this Agreement.

                CONFIDENTIALITY


13.01     Confidentiality.  For a period of ten (10) years
          from the Effective Date of this Agreement or
          five (5) years from the termination hereof,
          whichever occurs later:

               (i)  each party shall refrain from the
          use of Confidential Information furnished by the
          other party for any purpose inconsistent with
          this Agreement; and

               (ii) each party shall treat Confidential
          Information furnished by the other party as if
          it were its own proprietary information and
          shall not disclose it to any third party other
          than its Affiliates or consultants without the
          prior written consent of the other party who
          furnished such information; provided, however,
          that such Confidential Information may be
          disclosed if in the reasonable opinion of the
          recipient's counsel, such disclosure is
          necessary to comply with the requirements of any
          law, governmental order (including a court
          order), regulation or Internal Revenue Service
          request.  The recipient shall notify and consult
          with the disclosing party prior to such
          disclosure of information.

13.02     Advertising and Publicity. Subject to Section
          13.03 and except for such disclosures as are
          deemed necessary in IMMU's or MM's, as the case
          may be, reasonable judgment to comply with
          applicable law (such as, by way of example but
          not limitation, the securities laws of the
          United States), neither IMMU nor MM nor anyone
          acting on either's behalf will make any publicly
          disseminated oral or written disclosure relating
          or referring to, or use any advertising or
          publicity which relates or makes reference to,
          the other party, this Agreement or the terms
          hereof, without in each case having received the
          other party's prior approval (which approval
          will not be unreasonably withheld or delayed);
          each party will respond promptly to a disclosure
          request, but in any event not later than ten
          (10) business days from receipt of such a
          request.  The failure by a party to respond
          within such ten (10) business day period shall
          be deemed to be approval by such party of such
          disclosure, advertising or publicity.  The
          foregoing restriction shall not apply to any
          information which is contained in any previously
          issued press release or other disclosure that
          has been approved by the other party or that is
          otherwise indicated on Product labels,
          packaging, brochures or similar promotional
          material.

13.03     Disclosure Required by Law.  In the event that
          IMMU or MM shall be required to make disclosure
          of the other's Confidential Information as a
          result of the issuance of a court order or other
          government process, the party subject to such

<PAGE>
          requirement promptly, but in no event more than
          forty-eight (48) hours after learning of such
          court order or other government process, shall
          notify the other party and, at the other party's
          expense, the party subject to such requirements
          shall: (a) take all reasonably necessary steps
          requested by the other party to defend against
          the enforcement of such court order or other
          government process and (b) permit the other
          party to intervene and participate with counsel
          of its choice in any proceeding relating to the
          enforcement thereof.

13.04     Manuscripts.  MM shall use its best efforts to
          submit to IMMU for review at least thirty (30)
          days prior to submission for publication all
          manuscripts relating to the Product, its use, or
          the result of clinical trials written by MM's
          employees or by collaborators or clinical
          investigators participating in studies funded in
          whole or in part by MM.  If IMMU has not
          disapproved of the publication of the manuscript
          within thirty (30) days after receipt, the
          author may submit the manuscript for
          publication, and IMMU shall have no further
          right to comment.  Approval of any such
          manuscript shall not be reasonably withheld or
          delayed.  However, IMMU reserves the right to
          have deleted from the manuscript any material
          which may be reasonably considered Confidential
          Information.

          of its terms, and the interpretation of the
          rights and duties of the parties hereunder will
          be governed by the laws of the State of New
          Jersey, USA, excluding those laws that relate to
          the choice of law.  The exclusive jurisdiction
          and venue for any disputes arising out of or in
          connection with this Agreement will be an
          appropriate federal court located in the
          Southern District of New Jersey, and each party
          hereby consents to personal jurisdiction in such
          court and consents to service of process by
          means of certified or registered mail, return
          receipt requested.

14.02     Independent Contractor.  MM will perform all of
          its activities hereunder as an independent
          contractor, and nothing contained in this
          Agreement shall be deemed to create any
          association, partnership, joint venture, or
          relationship of principal and agent between the
          parties to this Agreement or any of their
          respective Affiliates, or to provide either
          party with the right, power or authority,
          whether express or implied, to create any such
          duty or obligation on behalf of the other party. 
          No employee or representative of a party shall
          have any authority to bind or obligate the other
          party to this Agreement for any sum
<PAGE>
          or in any manner whatsoever, or to create or
          impose any contractual or other liability on
          the other party without said party's
          authorized written approval.

14.03     Accounting Audits.  Each party shall maintain
          books of account relating to its expenditures
          pursuant to this Agreement, inventory levels and
          in the case of IMMU, Gross Sales and Net Sales,
          in accordance with U.S. generally accepted
          accounting standards with appropriate controls
          to insure that transactions are properly
          recorded.  Each party shall have the right, at
          its own expense, to have an independent
          certified public accountant of its own
          selection, reasonably acceptable to the other,
          examine at a time reasonably acceptable to the
          other, during normal business hours but not more
          than once each calendar year, the relevant books
          and records of account of the other, to
          determine whether appropriate accounting has
          been made under Sections 3.07, 5.03 and Article
          7 hereof.  Such independent certified accountant
          shall treat as confidential and shall not
          disclose to the party engaging such accountant
          any information other than that which is
          relevant to the rights of the engaging party
          hereunder or the performance by the other party
          of its obligations hereunder.  If such
          independent certified public accountant shall
          determine that the amounts due and owing by IMMU
          to MM during any calendar year exceed amounts
          actually paid by five percent (5%) or more, then
          IMMU shall, in addition to promptly paying such
          shortfall, reimburse MM for the fees and
          expenses of such accountants.  In the event of
          a dispute between the independent certified
          public accountants of MM and IMMU with respect
          to any matter called for by this Agreement, the
          parties shall select a third independent public
          accounting firm to arbitrate the dispute,
          provided that such firm shall have the authority
          only to select from among the positions of the
          original two firms that position which it deems
          most accurate.  The fees of such third firm
          shall be borne by the party whose position is
          not approved of by such arbitrator.

14.04     Interest Due on Late Payments.  If any amount
          payable by one party to the other (the "Creditor
          Party") hereunder is not paid when due, then
          without limiting any other rights which the
          Creditor Party may have as a result of such late
          payment, the amount unpaid shall bear interest
          until paid at a rate per annum equal to the
          prime rate published and as changed from time to
          time by Citibank, N.A. New York, New York (as
          reported in The Wall Street Journal) plus one
          percent (1%), with such interest to be paid on
          demand together with all costs incurred by the
          Creditor Party to collect the amounts due
          hereunder, including but not limited to
          reasonable attorneys fees and disbursements.

14.05     Taxes.  Each party shall bear all taxes imposed
          on it as a result of the performance by such
          party under this Agreement including, but not
          limited to, any sales tax, any tax on or
          measured by any payment required to be made
          hereunder, any registration tax, or any tax imposed
          with respect to the granting of other rights
          hereunder.  The parties shall cooperate fully with
          each other in obtaining and filing all requisite
          certificates and documents with the appropriate<PAGE>
<PAGE>
          authorities and shall take such
          further action as may reasonably be necessary to
          avoid the deduction of any withholding or
          similar taxes from any remittance of funds by
          one party to the other hereunder.

14.06     Employees.  Neither party shall have any
          responsibility for the  hiring, firing or
          compensation of the other party's employees or
          for any employee benefits of the other party's
          employees.

14.07     Assignment.  This Agreement shall be binding
          upon, and shall inure to the benefit of
          successors to a party hereto, but shall not
          otherwise be assignable without the prior
          written consent of both parties, except to the
          successor or assignee of all or a majority
          interest in either party's business relating to
          the licensed Product.  In the event all or a
          majority interest is assigned or transferred,
          each party shall notify the other prior to such
          assignment or transfer.

14.08     Notices.  Any notice required or permitted to be
          made or given hereunder shall (except as
          otherwise expressly provided herein) be in
          writing and shall be made or given to the other
          party by personal in-hand delivery; by
          telecopier or telex communication; by first-class mail, 
          postage prepaid; or by air courier

          in-hand delivery, or by telecopier or telex with
          confirmed transmissions, when performed; (ii) if

          air courier company.

14.09     Force Majeure.  In the event that either party
          is prevented from performing or is unable to
          perform any of its obligations under this Agreement
          due to any act of God, fire, casualty, flood,
          war, strike, lockout, failure of public utilities,
<PAGE>
          injunction or any act, exercise,
          assertion or requirement of governmental
          authority, including any governmental law, order
          or regulation permanently or temporarily
          prohibiting or reducing the level of research,
          development or production work hereunder or the
          manufacture, use or sale of Product, epidemic,
          destruction of production facilities, riots,
          insurrection, inability to procure or use
          materials, labor, equipment, transportation or
          energy sufficient to meet experimentation or
          manufacturing needs; or any other cause beyond
          the reasonable control of the party invoking
          this Section 14.09 provided such party shall
          have used its best efforts to avoid such
          occurrence; such party shall give notice to the
          other party in writing promptly, and thereupon
          the affected party's performance shall be
          excused and the time for performance shall be
          extended for the period of delay or inability to
          perform due to such occurrence.

14.10     Waiver.  The waiver by either party of a breach
          or a default of any provision of this Agreement
          by the other party shall not be construed as a
          waiver of any succeeding breach of the same or
          any other provision, nor shall any delay or
          omission on the part of either party to exercise
          or avail itself of any right, power or privilege
          that it has or may have hereunder operate as a
          waiver of any right, power or privilege by such
          Party.

14.11     Partial Invalidity.  The parties to this
          Agreement desire and intend that the terms and
          conditions of this Agreement be enforced to the
          fullest extent permissible under the laws and
          public policies applied in each jurisdiction
          where enforcement is sought.  If any particular
          term or condition of this Agreement is
          adjudicated, or becomes, by operation of law,
          invalid or unenforceable, this Agreement will be
          deemed amended to delete the portion which is
          adjudicated, or which becomes, by operation of
          law, invalid or unenforceable, provided,
          however, that where possible, a particular term
          or condition will be reduced to the extent
          necessary to permit the remainder of the
          particular term or condition to be enforced, the
          deletion or reduction to apply only with respect
          to the operation of the term or condition and
          the remainder of this Agreement to remain in
          full force and effect.  A deletion or reduction
          of any term or condition will apply only with
          respect to the operation of that term or
          condition in the particular jurisdiction in
          which such adjudication is made or becomes, by
          operation of law, invalid or unenforceable.

          the same instrument. This Agreement is entered
