such information concerning any serious adverse drug experience by either OHMEDA
PPD or GENSIA, the parties shall promptly consult each other and use their best
efforts to arrive at a mutually acceptable procedure for taking such possible
actions as appropriate or required under the circumstances; provided, however,
that nothing contained herein shall be construed as restricting the right or
duty of either party to make a required report or submission to the FDA or take
any other action that it deems to be appropriate or required by applicable law
or regulation. In any event, the responsibility of making any reports of adverse
drug experience or other required reports to the FDA shall be upon GENSIA as
holder of the product registration for each of the Products.

      4.5   RECALL ACTION.

      (a)   In the event OHMEDA PPD should be required or should voluntarily
decide to initiate a recall, Product withdrawal, or field correction of any
Products in the Territory pursuant to this Agreement, OHMEDA PPD through its
designee, the OHMEDA PPD Vice President of Quality, shall notify GENSIA and
provide a copy of its proposal, including the recall letter, for review prior to
initiation of such action. In conjunction with such recall, GENSIA shall assist
in the investigation to determine the cause and extent of the problem.

      (b)   In the event that GENSIA independently believes that a recall,
Product withdrawal, or field correction for Products may be necessary or
appropriate, GENSIA shall notify OHMEDA PPD through OHMEDA PPD's designee, the
OHMEDA PPD Vice President


                                      -17-
<Page>

of Quality, of GENSIA's belief, and the parties shall fully cooperate with each
other concerning the necessity and nature of such action.

      (c)   All coordination of any recall or field correction activities
involving Products shall be handled by OHMEDA PPD whether or not such action was
initially requested by GENSIA.

      4.6   EXPENSES. In the event that any Product is recalled as a result of
(1) the supply by GENSIA of Product that does not conform to the warranty set
forth in Section 3.1, or (2) the negligent or intentionally wrongful act of
GENSIA or its representatives, then GENSIA shall bear all of the costs and
expenses of such recall including without limitation expenses related to
communications and meetings with all required regulatory agencies, expenses of
replacement stock, the cost of notifying customers and costs associated with
shipment of recalled Product from customers and shipment of an equal amount of
replacement Product to those same customers. In the event that any Product is
recalled as a result of the negligent or intentionally wrongful act of OHMEDA
PPD or its representatives, then OHMEDA PPD shall bear all of the costs and
expenses of such recall, including without limitation expenses related to
communications and meetings with all required regulatory agencies, expenses of
replacement stock, the cost of notifying customers and costs associated with
shipment of recalled Product from customers and shipment of an equal amount of
replacement Product to those same customers. To the extent that the reason for
any recall of Products hereunder is in part the responsibility of GENSIA and in
part the responsibility of OHMEDA PPD or is not due to the fault of either
party, then the expenses shall be allocated in an equitable manner between the
parties.


                                      -18-
<Page>

      4.7   RECALL RECORDS. GENSIA shall maintain complete and accurate recall
records for such periods as may be required by applicable law, but in no event
less than three (3) years, of all the Products sold by it.

      5.    CONSIDERATION.

      5.1   TRANSFER PRICE. The price for each Product presentation ("Transfer
Price"), other than Hetastarch, to be delivered by GENSIA during the term of
this Agreement shall be the applicable Per Unit Materials Cost for each Product
presentation times * * * OHMEDA PPD shall pay to GENSIA, upon shipment to OHMEDA
PPD, the quantities of each Product presentation delivered to OHMEDA PPD
multiplied by the applicable Transfer Price for such Product presentation. The
terms of payment are net thirty (30) days from date of invoice.

      5.2   ADJUSTMENTS TO TRANSFER PRICE. Except as otherwise noted, set forth
on Exhibit C is a calculation by GENSIA of the Per Unit Materials Cost for each
Product presentation based * * * together with the resulting Transfer Price for
each Product presentation based on such Per Unit Materials Cost. The Per Unit
Materials Costs portion of the Transfer Price of each Product presentation shall
be adjusted at the beginning of each Annual Period during the term of this
Agreement. GENSIA shall provide written notice of such adjustment thirty (30)
days prior to the date of the adjustment. Such adjustment will be based on the
then current actual invoice costs of Materials used to manufacture and package
Products to be delivered to OHMEDA PPD during the applicable period.

      5.3   ROYALTY. In addition to the Transfer Price, for each Product
presentation detailed in Section 5.1 hereof, other than Hetastarch, OHMEDA PPD
will pay to GENSIA a royalty, "Royalty", * * * on Products delivered by GENSIA
and sold by OHMEDA PPD in the Territory.

----------

                                      -19-
<Page>

OHMEDA PPD will provide payment to GENSIA on a quarterly basis not more than
sixty (60) days following the end of each of the first three (3) quarters of an
Annual Period. Each payment shall be accompanied by a statement showing the Net
Sales for the applicable quarter and the calculation of the royalty fee in
accordance with this Section 5.3.

      5.4   ANNUAL RECONCILIATION AND ADJUSTMENT. Within sixty (60) days after
the end of an Annual Period, OHMEDA PPD shall deliver to GENSIA a report setting
forth a determination of the Royalty for the applicable Annual Period calculated
in accordance with Section 5.3, using aggregate Net Sales and Transfer Prices
for the applicable Annual Period, including any year-end reconciliations. Such
Royalty for the Annual Period shall be reduced by the aggregate total of Royalty
payments made by OHMEDA PPD for each of the previous three (3) quarters during
the Annual Period. If the resulting amount is a positive number, then OHMEDA PPD
shall owe GENSIA that amount. If the resulting number is a negative number, then
GENSIA shall owe OHMEDA PPD that amount.

      5.5   HETASTARCH.

      (a)   The purchase price payable to GENSIA for each unit of Hetastarch to
be delivered during the term of this Agreement shall be based on unit sales by
OHMEDA PPD during each Annual Period in accordance with the following schedule:

      * * *

For purposes of this Section 5.5, "Average Selling Price" shall mean Net Sales
for the applicable period divided by the number of units sold, less returns,
during the applicable period.

                                      -20-
<Page>

      (b) For invoicing purposes, the parties shall set an interim per unit
price of Hetastarch to be paid by OHMEDA PPD. The terms of payment are net
thirty (30) days from the date of invoice. The initial interim price per unit of
Hetastarch is set forth in Exhibit C. Such interim price per unit shall be
adjusted at the time of receipt of the next FDA ANDA deficiency letter related
to Hetastarch and thereafter shall be adjusted quarterly on the basis of * * *
The interim per unit price paid by OHMEDA PPD shall be subject to
reconciliations with the actual per unit purchase price in accordance with
Section 5.5(c).

      (c) Within sixty (60) days after the end of each quarter during an Annual
Period, OHMEDA PPD shall deliver to GENSIA a report setting forth a calculation
of the amount of the purchase price payable to GENSIA for Hetastarch for the
Annual Period through the end of the applicable quarter. * * * The amount of the
purchase price for the Annual Period through the end of the applicable quarter
as determined in this Section 5.5 shall be reduced by the interim purchase price
paid by OHMEDA PPD for each unit sold during the Annual Period through the end
of the applicable quarter on a FIFO basis, and then further appropriately
reduced or increased as a result of any prior quarterly adjustments within the
Annual Period. If the resulting number is positive, then such amount shall be
payable to GENSIA. If the resulting number is negative, then such amount shall
be payable to OHMEDA. Any monies due shall be payable within ten (10) days of
the delivery of the report. An example of Hetastarch compensation payments for
an Annual Period is set forth in Schedule 5.5.

      OHMEDA PPD may return damaged or shortdated units of Hetastarch for credit
(determined as set forth below) provided that, in the case of shortdated units,
OHMEDA has used commercially responsible efforts to sell such units. In the
event that any units purchased by OHMEDA PPD ultimately cannot be sold by OHMEDA
PPD, then the credit per unit to

----------
*** Confidential material redacted and separately filed with the Commission


                                      -21-
<Page>

OHMEDA shall be equal to the interim price per unit (as defined in Section 5.5
(b) above) reduced by the actual GENSIA cost to manufacture. For purposes of
this Section 5.5, "shortdated" shall mean having less than six (6) months shelf
life remaining.

      (d) In the event that the Average Selling Price for units of Hetastarch
drops below * * * during any quarterly reporting period hereunder, then the
parties shall renegotiate the purchase price payable to GENSIA for units of
Hetastarch on a * * * consistent with the other Products set forth on Exhibit C.

      5.6 TAXES. All federal, state, district, local or other governmental
authority income or similar tax measured by income that is imposed on either
party as a result of income, shall be the responsibility of such party. Any
federal, state, district, local or other governmental authority sales or use
tax, excise or similar tax assessed on the sale of Products by OHMEDA PPD shall
be paid by OHMEDA PPD.

      5.7 INSPECTION. During the term of this Agreement and for a period of one
(1) year thereafter, each party shall have the right, at its own expense, to
have a public accounting firm to which the other party has no reasonable
objection examine the relevant books and records of account of such party during
business hours not more often than once each calendar year to determine whether
appropriate accounting and payment have been made pursuant to this Section 5.
Such inspection rights shall be limited to the records relating to the three
most recently concluded Annual Periods at the time of each inspection provided
that no such Annual Period shall be subject to inspection more than once. The
accounting firm shall disclose to the requesting party only whether the records
are correct or not and the specific details concerning any discrepancies. No
other information shall be shared. Each party shall preserve all relevant

----------
*** Confidential material redacted and separately filed with the Commission


                                      -22-
<Page>

records for a period of seven (7) years from the date of the applicable record.
If a party proposes to destroy any relevant records that have been held for
seven (7) years, then such party shall first advise the other party in writing,
and if the other party objects to such destruction, it shall store for or
deliver such relevant records to the other party, at the other party's expense.

      5.8   CUSTOMER PRICING. OHMEDA PPD shall have sole discretion in setting
customer pricing for the Products in the Territory. Nevertheless, it is not the
intention of OHMEDA PPD to offer to sell the Products as loss leaders in
connection with the promotion of other OHMEDA PPD products.

      6.    TERM AND TERMINATION.

      6.1   TERM AND RENEWAL. The obligation of the parties hereunder shall
effectively commence on January 1, 1996 and continue for five (5) Annual Periods
provided the Agreement will automatically be extended for additional and
successive terms of one (1) year each unless either party terminates this
Agreement effective the end of the initial term or any renewal term upon two (2)
years prior written notice.

      6.2   TERMINATION FOR BREACH. This Agreement may be terminated by either
party if the other party fails to remedy and make good any material default in
the performance of any condition or obligation under this Agreement within sixty
(60) days of the date a written notice of such default and intention to
terminate is sent to the defaulting party.

      6.3   TERMINATION FOR BANKRUPTCY. This Agreement may be terminated by
either party, forthwith, or at any time thereafter by notice to the other if the
other files a petition of


                                      -23-
<Page>

bankruptcy, is adjudged bankrupt, takes advantage of any insolvency act or
executes a bill of sale, deed of trust or assignment for the benefit of
creditors.

      6.4   TERMINATION FOR FORCE MAJEURE. This Agreement may be terminated by a
party, upon thirty (30) days written prior notice in the event of the other
party's inability to substantially perform its obligations hereunder for more
than ninety (90) days due to an event of force majeure.

      6.5   NO WAIVER. The failure of either party to terminate this Agreement
by reason of the breach of any of its provisions by the other party shall not be
construed as a waiver of the rights or remedies available for any subsequent
breach of the terms and provisions of this Agreement.

      6.6   ACCRUED LIABILITIES. Termination of this Agreement for any reason
shall not discharge either party's liability for obligations incurred hereunder
at the time of such termination and shall be without prejudice to the rights and
remedies of either party with respect to any antecedent breach of any of the
provisions of this Agreement. GENSIA shall deliver and OHMEDA PPD shall pay
GENSIA for any finished Products that were ordered by OHMEDA PPD prior to
termination. Upon termination of this Agreement, OHMEDA PPD shall have the right
to sell any of its remaining inventory of Products in the Territory on the same
terms as set forth in this Agreement.

      6.7   PROPERTY. In the event of termination of this Agreement for whatever
cause, in addition to the other obligations of the parties hereunder, each party
shall return to the other party or to the other party's designee no later than
thirty (30) days after the effective date of termination all of such other
party's property, including, but not limited to, all proprietary


                                      -24-
<Page>

information, in its possession, except to the extent required to be retained by
law or to comply with such party's continuing obligations hereunder.

      7.    INDEPENDENT CONTRACTORS.

      The parties acknowledge, agree and declare that the relationship hereby
established between them is solely that of provider and recipient of
manufacturing services and that each party hereto is an independent contractor
with respect to the other.

      8.    INDEMNIFICATION.

      8.1   INDEMNIFICATION BY GENSIA. GENSIA agrees to indemnify, defend and
hold harmless OHMEDA PPD, its affiliates and their respective employees against
any and all third-party claims, losses, damages and liabilities, including
reasonable attorney's fees, incurred by any of them arising out of any breach of
any obligation by GENSIA hereunder, any misrepresentation by GENSIA hereunder,
any negligent or intentionally wrongful act or omission by GENSIA in connection
with the manufacture of Products hereunder, or any inadequacy or failure to warn
in the prescribing information for the Products unless such prescribing
information has been modified by the mutual consent of the parties after ANDA
approval.

      8.2   INDEMNIFICATION BY OHMEDA PPD. OHMEDA PPD agrees to indemnify,
defend and hold harmless GENSIA, its affiliates and their employees against any
and all third-party claims, losses, damages and liabilities, including
reasonable attorney's fees, incurred by any of them arising out of any breach of
any obligation by OHMEDA PPD hereunder or any misrepresentation by OHMEDA PPD
hereunder or any negligent or intentionally wrongful act or


                                      -25-
<Page>

omission of OHMEDA PPD in connection with the distribution or sale of the
Products in the Territory.

      8.3   PATENT INDEMNITY. GENSIA shall, at its expense, defend or settle any
actions brought against OHMEDA PPD, its Affiliates, its employees, or any of
their customers alleging that any of the Products, or the use of any of them in
accordance with any approved indications, infringes one or more claims of a
patent. GENSIA shall pay all damages and costs awarded by a court of competent
jurisdiction, unappealed and unappealable.

      8.4   PROCEDURE. If OHMEDA PPD, its affiliates or their respective
employees or customers, or GENSIA, its affiliates or their respective employees
(in each case an "Indemnified Party") receive any written claim which such
Indemnified Party believes is the subject of indemnity hereunder by GENSIA or
OHMEDA PPD as the case may be (in each case an "Indemnifying Party"), the
Indemnified Party shall, as soon as reasonably practicable after forming such
belief, give notice thereof to the Indemnifying Party; provided, that the
failure to give timely notice to the indemnifying Party as contemplated hereby
shall not release the Indemnifying Party from any liability to the Indemnified
Party unless the Indemnifying Party demonstrates that the defense of such claim
is prejudiced by such failure. The Indemnifying Party shall have the right, by
prompt notice to the Indemnified Party, to assume the defense of such claim, at
its cost, with counsel reasonably satisfactory to the Indemnified Party. If the
Indemnifying Party does not so assume the defense of such claim or, having done
so, does not diligently pursue such defense, the Indemnified Party may assume
such defense, with counsel of its choice, but at the cost of the Indemnifying
Party. If the Indemnifying Party so assumes such defense, it shall have absolute
control of the conduct of the litigation; the Indemnified Party may,
nevertheless, participate therein through counsel of its choice and at its cost.
The party not


                                      -26-
<Page>

assuming the defense of any such claim shall render all reasonable assistance to
the party assuming such defense, and all out-of-pocket costs of such assistance
shall be for the account of the Indemnifying Party. No such claim shall be
settled other than by the party defending the same, and then only with the
consent of the other party, which shall not be unreasonably withheld; provided,
that the Indemnified Party shall have no obligation to consent to any settlement
of any such claim which imposes on the Indemnified Party any liability or
obligation which cannot be assumed and performed in full by the Indemnifying
Party.

      8.5   MODIFICATIONS TO PRESCRIBING INFORMATION. The parties shall be
mutually responsible with respect to any modifications to prescribing
information for a Product that are agreed to by the parties after ANDA approval
of such Product. To the extent that a third party claim arises out of such
modifications to prescribing information, then any resulting liabilities,
losses, costs, damages, or expenses shall be equitably allocated between the
parties.

      9.    INSURANCE.

      Each party shall carry comprehensive general liability insurance,
including product liability insurance against claims for bodily injury or
property damage in an amount of not less than $3,000,000 per occurrence and
$8,000,000 in the aggregate. Such policy shall be endorsed to include the
following: (a) the policies shall provide for thirty (30) days' notice to the
other party of cancellation or material change in the coverage before such
cancellation or change takes effect; and (b) contractual liability including
this Agreement. Each party shall carry the insurance coverage set forth herein
during the term of this Agreement and for five (5) years following termination
of this Agreement. Such insurance shall be with insurance companies


                                      -27-
<Page>

licensed to do business in California and the insurers shall have a Best's
Insurance rating of A:X or better.

      10.   REMEDIES AID LIMITATION OF LIABILITY.

      10.1  REMEDIES. In the event that GENSIA fails to supply Products in
accordance with the terms of this Agreement, then, unless an event of force
majeure has occurred, GENSIA shall reimburse OHMEDA PPD any increased cost of
obtaining Products from an alternative source, provided that OHMEDA PPD uses
reasonable commercial efforts to obtain such Products from an alternative
generic source. In addition, GENSIA agrees to reimburse OHMEDA PPD for any
losses, liabilities, or expenses that are incurred as a result of the inability
of OHMEDA PPD to comply with its supply obligations in customer agreements when
such inability to supply by OHMEDA PPD arises as a result of GENSIA's failure to
supply Products in accordance with the terms of this Agreement. A copy of an
illustrative OHMEDA PPD supply guarantee clause with a customer is set forth in
Exhibit F.

      10.2  LIMITATION. EXCEPT AS SET FORTH IN SECTION 10.1, NEITHER PARTY SHALL
BE LIABLE TO THE OTHER FOR SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES UNDER
ANY CIRCUMSTANCES OR UNDER ANY THEORY OF LAW.

      11.   FORCE MAJEURE AND EXCESSIVE DEMAND.

      11.1  FORCE MAJEURE. Neither party shall be liable to the other for
default or delay in the performance of its obligations under this Agreement, if
such default or delay shall be caused directly or indirectly by accident, fire,
flood, riot, war, act of God, embargo, strike, failure or


                                      -28-
<Page>

delay of normal source of supply of materials, or delay of carriers, or
governmental orders or regulations, provided same are not due to the fault or
neglect of such party and provided further that any such delay or failure shall
be remedied by such party as soon as possible after the removal of the cause of
such failure or delay.

      11.2  EXCESSIVE DEMAND. In the event of a shortage or anticipated shortage
of the Products and/or delay in shipment or delivery occasioned by any of the
force majeure events set forth in Section 11.1 herein, GENSIA will endeavor to
allocate equitably the available product to OHMEDA PPD and to GENSIA's own use
on the basis of historic useage over the previous twelve month period. If the
demand by OHMEDA PPD during an Annual Period exceeds the amount forecasted in
the initial Demand Schedule for such Annual Period provided by OHMEDA PPD,
GENSIA will provide priority to OHMEDA PPD products up to 125% of the forecasted
quantity set forth in such Demand Schedule. GENSIA will use commercially
reasonable efforts to allocate equitably any demand by OHMEDA PPD in excess of
125% of such forecasted annual quantity.

      12.   CONFIDENTIALITY.

      Any information or data (including but not limited to, any technical
information, experience or data) regarding either party's formulations, plans,
programs, plants, processes, technical materials, products, production
requirements, standard specifications, costs, equipment, operations, procedures,
instructions or customers (all of which is herein referred to as "Confidential
Information") is the sole property of the respective party. Each party shall
treat the other party's confidential information in the same protective manner
that it treats its own confidential information. Parties shall not use, except
for the purpose of carrying out this


                                      -29-

Agreement, or disclose to others or permit their employees or agents to use,
except for the purpose of carrying out this Agreement, or disclose to others,
during the term of this Agreement and for a period of five (5) years from the
date of termination or expiration of this Agreement Confidential Information
which has heretofore come or hereafter may come within the knowledge of, or
which has been or may hereafter be acquired or developed by the respective
party, its employees or agents, in the performance of any services hereunder.
This paragraph shall not prevent either party from using or disclosing to others
information:

            (i) which is known to the receiving party at the time it is
      disclosed by or obtained from the disclosing party, which knowledge can be
      established by competent evidence; or

            (ii) which is, or through no fault of the receiving party becomes,
      lawfully available to the public; or

            (iii) which lawfully becomes available to the receiving party from a
      source other than the disclosing party. Upon termination of this
      Agreement, if requested, the receiving party shall deliver to the
      disclosing party all notes, drawings, blueprints, manuals, letters,
      notebooks, reports of or pertaining to Confidential Information, including
      all copies thereof, and all other Confidential Information which is in the
      possession of or under the control of the receiving party.

      Parties shall restrict access to Confidential Information to as few as
practicable of their employees, and in all cases shall restrict such knowledge
to only those employees who are directly connected with the performance of the
services hereunder.

      13.   COMPLIANCE WITH LAW.

      Each party shall comply with, and shall not be in violation of, any valid
applicable national, state or local statutes, laws, ordinances, rules,
regulations, or other governmental orders in the Territory.

      14.   ADDITIONAL PRODUCTS.

      During the twelve (12) month period after the execution of this Agreement,
OHMEDA PPD shall have the option to add any of the products listed in Exhibit E
to this Agreement by providing written notice to GENSIA. Immediately after
receipt by GENSIA of such notice of the exercise of OHMEDA PPD's right to
include an additional product pursuant to this Section 14, then such product
shall be incorporated into the definition of "Products" hereunder and GENSIA
shall use commercially reasonable efforts to obtain ANDA approval of such
product in accordance with Section 4.1 and thereafter shall supply such product
on commercial terms to be negotiated by both parties.

      15.   CAPITATION AGREEMENTS.

      To the extent that OHMEDA PPD offers capitation arrangements to customers
that include the supply of Products and such capitation arrangements are not on
a product basis, then the parties shall act in good faith to agree on a
methodology to equitably calculate net sales of such Products covered by such
capitation arrangements on a different basis than set forth in Section 1.8.

             "In the event of the failure of Vendor
             (OHMEDA-PPD) to perform in accordance
             with the terms of this Agreement,
             (Buying Group Member) may purchase the
             Products from other sources and the

             to [Buying Group Member] for all
             reasonable costs in excess of the Award
             Price."

      The clause set forth above is illustrative of supply guarantee obligations
of OHMEDA PPD in customer agreements. It is understood and agreed that
incorporation of this clause as an example is not to be deemed definitive of
such obligations and furthermore is not intended to foreclose such remedies as
may be available to OHMEDA's customers under the applicable provisions of the
Uniform Commercial Code in the event of a failure to supply.

                          ADDENDUM TO MANUFACTURING AND
                             DISTRIBUTION AGREEMENT

      Pursuant to Section 14 of the Manufacturing and Distribution Agreement
dated as of February 27, 1996 (the "Agreement"), the parties hereto agree that
propofol shall be added to the Agreement under the terms and conditions set
forth in this addendum (the "Addendum"). Except as specifically set forth
herein, or except to the extent they are inconsistent with the terms and
conditions of this Addendum, the terms and conditions of the Agreement shall
apply to the manufacture and distribution of propofol pursuant hereto. Except as
otherwise set forth herein, capitalized terms shall have the meanings ascribed
to them in the Agreement.

      1.    PRODUCT. For purposes of this Addendum, the term "Product" shall
mean the following products, manufactured and packaged by Gensia or its
permitted contract manufacturer in finished format with the OHMEDA PPD label:

      (a)   Propofol filled in 20mL, 50mL and 100mL vials (10mg/mL)

      (b)   Propofol filled in 20mL syringes (10mg/mL)

      2.    TERM. This Addendum shall become effective on the date set forth
below, and shall remain in effect for a period of two (2) years from the date of
approval of GENSIA's ANDA for the Product described in Section 1(a), above
("Vial Product").

      3.    LABELING. The Product shall be finished in OHMEDA PPD trade dress
provided by OHMEDA PPD, in accordance with the provisions of Section 3.7 of the
Agreement.

      4.    FEE. OHMEDA PPD shall pay GENSIA the sum of *** on October 1, 1996.

      5.    PRICE. The price for each presentation of the Product is set forth
in Schedule A attached hereto. In the event both Abbott Laboratories and OHMEDA
PPD are actively selling propofol (other than GENSIA manufactured propofol) in
the Territory on the first anniversary date of the approval of GENSIA's ANDA for
the Product, ***. GENSIA and OHMEDA PPD will cooperate in identifying methods to
reduce the cost of Product described in Section 1(b), above ("Syringe Product"),
***. GENSIA and OHMEDA PPD will also work to reduce the cost of Vial Product,
and cost savings that relate directly to such cost reduction efforts will be
passed on to OHMEDA PPD in the form of unit price reductions on future units
purchased as such savings are realized. GENSIA shall not be paid any royalty
pursuant to Section 5.3 of the Agreement with respect to the Product
presentations purchased by OHMEDA PPD pursuant to this Addendum.

      6.    REQUIRED PURCHASES. OHMEDA PPD shall *** of Product from GENSIA in

the term of this Addendum. Such minimum unit purchase obligation may be
fulfilled by the purchase of any mix of available presentations of the Product.
In the event OHMEDA PPD fails to purchase such minimum quantity of units during
either of the foregoing twelve (12) month periods, OHMEDA PPD shall pay to
GEENSIA, within thirty (30) days after the close of such twelve (12) month
period, a cash payment equal to the difference between (a) the amounts which
would have been due GENSIA from OHMEDA PPD pursuant hereto had OHMEDA PPD
purchased such minimum quantity of Product from GENSIA and (b) the actual
billings to OHMEDA PPD by GENSIA for such twelve (12) month period for Product.
For purposes of this Section 6, the payments referred to in clause (a) above
shall be calculated by assuming that OHMEDA PPD would have purchased the same
mix of presentations of the Product as the then current IMS mix of propofol
dosing sizes as reported for the twelve (12) months ending at the end of the
quarter preceding the close of the contract year in question. OHMEDA PPD may
purchase a *** of Product from GENSIA in each twelve (12) month period during
the term of this Addendum. GENSIA's obligation under Section 11.2 of the
Agreement to provide priority to OHMEDA PPD products shall apply to only 100% of
the forecasted quantity of Product. Notwithstanding anything in the foregoing to
the contrary, purchases by OHMEDA PPD of units of *** of the total units of
Product purchased hereunder.

      7.    PAYMENT TERMS. Payment terms for Product purchased hereunder shall
be net thirty (30) days from the date of shipment.

      8.    FORECASTS AND ORDERS. GENSIA shall keep OHMEDA PPD apprised of the
status of OHMEDA PPD's ANDA filing with respect to the Product and shall
immediately notify OHMEDA PPD in writing of approval by the FDA. OHMEDA PPD will
provide GENSIA with an initial forecast for the Product in writing upon receipt
from GENSIA of a copy of the conclusory paragraph of the ANDA deficiency letter
(or such other paragraph or portions of such paragraph as characterizes the
deficiency as major or minor) from FDA with respect to the Products. In the
event of a minor deficiency, such initial forecast shall be provided within five
(5) business days of OHMEDA PPD's receipt of such portions of the deficiency
letter; in the event of a major deficiency, such initial forecast shall be
provided within ninety (90) days of OHMEDA PPD's receipt of such portions of the
deficiency letter. GENSIA shall use its best efforts to deliver Product ordered
for the first two (2) months following FDA approval of the Product on the
delivery date required by OHMEDA PPD, and shall thereafter deliver products
within sixty (60) days from orders submitted in accordance with the procedures
set forth in Section 2.4 of the Agreement.

foregoing, Contracted Customers shall include hospitals, alternate care sites,
wholesalers/distributors, and group purchasing organizations and shall
specifically exclude persons for whom Gensia Sicor contract manufactures the
Products and any other persons who contract or market Products manufactured by
Gensia Sicor on Gensia Sicor's behalf.

      1.14 "Transition Period" shall mean the time period between the date of
this Amendment and December 31, 1999.

      1.15 "Variable Standard Costs" shall mean, for the purposes of this
Agreement, Gensia Sicor's actual variable standard costs for each Product

      1.16 "Full Standard Costs" shall mean, for the purposes of this Agreement,

2.    The Agreement shall be amended to add the following provisions after
Section 2.6 hereof:

      2.7 EXCLUSIVITY. Subject to Section 2.8 hereof, during the term of this
Agreement and as of the date of this Amendment, Gensia Sicor grants to Baxter
PPI the exclusive right (exclusive even as to Gensia Sicor) to market and sell
the Products in the Territory. After the Transition Period set forth in Section
2.8 hereof, the Products shall be marketed and sold solely in Baxter trade dress
or in other such trade dress as approved by Baxter PPI. Notwithstanding


                                                                          Page 1
<Page>

the foregoing nothing herein shall require Gensia Sicor to breach its existing
agreement with American Pharmaceutical Partners ("APP").

      2.8 TRANSITION PERIOD. Except as set forth below, the Products may be
marketed and sold in Gensia Sicor trade dress only to Contracted Customers until
the earlier of the expiration of such contracts or December 31, 1999. As of the
date of this Amendment, Gensia Sicor shall assign its contracts with Contracted
Customers to Baxter PPI and, subject to the terms set forth therein, Baxter PPI
shall supply such Contracted Customers with Product in Baxter PPI trade dress
after Product containing Gensia Sicor trade dress is exhausted. As soon as
reasonably practical Gensia Sicor shall take all commercially reasonable steps
to obtain consents to assign such contracts where consent is required. Following
the date of this Amendment and having successfully obtained consents to
assignment of Gensia Sicor contracts, Gensia Sicor shall not produce any
additional Product, except for atracurium, in Gensia Sicor trade dress.
Atracurium may be produced in Gensia Sicor trade dress until Baxter PPI takes
its first delivery of bulk atracurium besylate from Gensia Sicor.
Notwithstanding the foregoing, Products shall continue to be sold to Contracted
Customers in Gensia Sicor trade dress after the Transition Period, and Gensia
Sicor may continue to manufacture such Products in Gensia Sicor trade dress
after the Transition Period, if and only to the extent failure to do so would
cause Gensia Sicor to be in breach of any agreement with a Contracted Customer
or give Gensia Sicor reasonable grounds to believe that such Contracted Customer
would terminate such agreement, and provided that Gensia Sicor has used
reasonable commercial efforts to cause such Contracted Customer to consent to
substitution of Baxter PPI-labeled Product for Gensia Sicor-labeled Product.
Gensia Sicor shall attach to this Amendment a list of Contracted Customers,
Products covered and contract term. Royalty payments for Transition Period sales
shall be described in Section 5.3.

      2.9 LICENSE. Subject to the provisions of this Section 2.9, Gensia Sicor
grants to Baxter PPI an exclusive license for the term of this Agreement to
make, have made, use and sell the Products (including the technology described
in Gensia Sicor's Product ANDAs and grandfathered Products documentation or any
changes or supplements thereto in the Territory); provided that Baxter PPI shall
not be permitted to sublicense such right other than to its Affiliates. In
consideration of the grant of such license, Baxter PPI agrees to (a) pay a
Royalty described in Section 5.3 hereof, and (b) purchase *** of both Baxter PPI
and Gensia Sicor combined (current) generic Product requirements for bulk
atracurium besylate from Gensia Sicor or its Affiliates at a price of *** upon

substance. Baxter PPI agrees to make commercially reasonable efforts to file its
supplemental ANDA for Gensia Sicor bulk atracurium besylate by October 31, 1998
and further to use commercially reasonable efforts to pursue the ANDA supplement
through to approval.

      2.10 DILTIAZEM SUPPLY. Baxter PPI agrees to purchase Gensia Sicor's

its contracts with other suppliers for such product existing as of the date of

the Variable Standard Costs, and the Full Standard Costs shall be adjusted at
the beginning of each Annual Period during the term of this Agreement. A Per

prior to the date of the adjustment. Such adjustment will be based on the
then current actual invoice costs of Materials used to manufacture and
package products to be delivered to Baxter PPI, the actual Variable Standard
Costs and the actual Full Standard Costs during the applicable period.

      to be delivered during the Term following the expiration of the Initial
      Hetastarch Purchase Price set forth in Section 5.5(a) above shall be the

      the invoice.

            (c) The total price payable to Gensia Sicor shall be the Transfer
      Price for Hetastarch as set forth in Section 5.5 (b) and a Royalty *** of

      the final total payment of Royalty due Gensia Sicor.

            (d) Baxter PPI may return Hetastarch units damaged for credit
      (determined as set forth below). Baxter PPI may return short dated

      The credit per unit to Baxter PPl shall be equal to the Hetastarch
      Purchase Price per unit (as defined in Section 5.5 (a) & (b) above). For
      the purposes of this Section 5.5, "shortdated" shall mean having less than

Material that has less than six (6) months' dating remaining at the time of

            (b) For purposes of calculating the Percentage Payment for each

of ***. The amount of the Propofol Product Incentive for each calendar year
during the term of this Agreement shall be (a) for calendar year 1999, ***; (b)

Notwithstanding the foregoing, (x) no Propofol Performance Incentive shall be

Incentive (at a rate of ***) for that number of units of Propofol less than the
Propofol Performance Target number of units which Baxter PPI sold as of December
31, 2001; provided, however, if Gensia Sicor becomes unable to manufacture
Propofol due to an event of Force Majeure occurring prior to December 31, 2001,
and the aggregate number of units of Propofol which Baxter PPI sold as of
December 31, 2001 is *** units, then for purposes of this Section 5.9 and

of units of Propofol which Baxter PPI sold as of December 31, 2001.

      5.10 CONTRACTS. Baxter PPI represents and warrants that, as of March 22,
1999, Propofol is included on group purchasing contracts as a sole source award
(or under terms and conditions that convert into a sole source award within
sixty (60) days after Baxter labeled Propofol is available in the marketplace)

            5.3.2 ENALAPRILAT PERCENTAGE PAYMENT.

            (a) Notwithstanding the foregoing, the total amount payable by
