                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                MARCH 31, 1999

1. ORGANIZATION AND PRINCIPLES OF CONSOLIDATION

     ORGANIZATION

     Gensia Sicor Inc. ("Gensia Sicor" or the "Company"), a Delaware
corporation, was incorporated November 17, 1986.  Gensia Sicor is a specialty
pharmaceutical company focused on the development, manufacture and marketing of
products for worldwide oncology and injectable pharmaceutical markets.  The
company is headquartered in Irvine, California.  On February 28, 1997, Gensia
Sicor completed the acquisition of Rakepoll Holding B.V. ("Rakepoll Holding")
from Rakepoll Finance N.V. ("Rakepoll Finance").  Rakepoll Holding is the parent
company of three specialty pharmaceutical businesses: SICOR-Societa Italiana
Corticosteroidi S.p.A. ("Sicor") of Milan, Italy, and two companies located in
Mexico:  Lemery, S.A. de C.V. ("Lemery") and Sicor de Mexico, S.A de C.V.
("Sicor de Mexico"). In addition, in December 1997, Sicor purchased a 50% equity
interest in Diaspa S.p.A. ("Diaspa"), an Italian company engaged in the
manufacture of certain raw materials used in Sicor's business.  In June 1998,
Sicor purchased the remaining 50% of Diaspa.

     PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of the Company
and its subsidiary companies, all of which are wholly owned, except for
Metabasis Therapeutics, Inc ("Metabasis"), which is 92% owned.  An affiliated
company in which the Company does not have a controlling interest, or for which
control is expected to be temporary, is accounted for using the equity method.
The four wholly-owned subsidiaries are as follows: Rakepoll Holding B.V., Gensia
Sicor Pharmaceuticals, Inc. (formerly Gensia Laboratories, Ltd. and herein
referred to as "Gensia Sicor Pharmaceuticals"), Gensia Development Corporation
and Genchem Pharma Ltd. ("Genchem Pharma").  All significant intercompany
accounts and transactions have been eliminated.  Minority interest at March 31,
1999 represents minority stockholders' proportionate share of the equity in
Metabasis only which is included in other noncurrent assets.  As noted above,
the remaining 50% of Diaspa was acquired during the second quarter of 1998, and
accordingly, Diaspa became a wholly-owned subsidiary in the second quarter of
1998.

     In the opinion of the Company, all adjustments, consisting only of normal
recurring adjustments, necessary for the fair statement of the results for the
three-month periods ended March 31, 1999 and 1998 have been made.  The results
of operations for the three-month period ended March 31, 1999 are not
necessarily indicative of the results to be expected for the full fiscal year.

     The accompanying consolidated financial statements should be read in
conjunction with the audited financial statements and notes thereto included in
the Company's 1998 Form 10-K filed with the Securities and Exchange Commission.

     FOREIGN CURRENCY TRANSLATION

     The financial statements of subsidiaries outside the United States, except
those subsidiaries located in highly inflationary economies, are generally
measured using the local currency as the functional currency.  Assets and
liabilities of these subsidiaries are translated at the rates of exchange at the
balance sheet date.  The resulting translation adjustments are included in
accumulated other comprehensive income (loss), a separate component of
stockholders' equity.  Income and expense items are translated at average
monthly rates of exchange.

                                MARCH 31, 1999

     RECLASSIFICATIONS

     Certain prior year amounts have been reclassified to conform to the
classifications used in 1999.

2.   NET LOSS PER SHARE

     Basic net loss per share is computed by dividing net loss, after deducting
preferred stock dividends, by the weighted average number of common shares
outstanding during the period.  Shares issuable upon exercise of outstanding
stock options and warrants have not been included in the computation of diluted
net loss per share since the effects of such conversions and exercises would be
anti-dilutive.

3.   COMPREHENSIVE NET INCOME (LOSS)

     As of January 1, 1998, the Company adopted the Financial Accounting
Standards Board Statement No. 130, "Reporting Comprehensive Income" ("SFAS
130").  The new standard established new rules for the reporting and display of
comprehensive income and its components; however, the adoption of this statement
had no impact on the Company's net loss or stockholders' equity.  SFAS 130
requires unrealized gains or losses on the Company's available-for-sale
securities and foreign currency translation adjustments, which prior to adoption
were reported separately in stockholders' equity, to be included in other
comprehensive income (loss).

4.   INVENTORIES

     Inventories at March 31, 1999 and December 31, 1998 consisted of (in
thousands):

5.   CONTINGENCIES

     In July 1998, the Company was named as a defendant in a complaint filed by
Protocol Systems, Inc. ("Protocol Systems").  The complaint alleges breach of a
supply agreement (the "Supply Agreement").  Protocol Systems alleges damages
estimated at approximately $10.8 million, plus any amounts which it may owe to a
third-party vendor.  Gensia Sicor believes that the amount of the claim is
significantly overstated for a variety of reasons and plans to vigorously defend
itself against this claim.  Based on a review of the current facts and
circumstances, management has recorded a provision for its estimate of liability
related to this lawsuit.  The ultimate outcome with respect to the lawsuit could
have a material adverse effect on the Company's financial position, results of
operations or cash flows.
 
     The Company is also a defendant in various actions, claims, and legal
proceedings arising from its normal business operations.  Management believes
they have meritorious defenses and intends to vigorously defend against all
allegations and claims.  As the ultimate outcome of these matters is uncertain,
no contingent liabilities or provisions have been recorded in the accompanying
financial statements for such matters.  However, in management's opinion,

liabilities arising from such matters, if any, will not have a material adverse
effect on consolidated financial position, results of operations or cash flows.
 
6.   SUBSEQUENT EVENT

     In April 1999, the Company's wholly-owned subsidiary, Gensia Sicor
Pharmaceuticals, filed a lawsuit in the Superior Court of California for Orange
County against American Pharmaceutical Partners ("APP") for breach of contract,
breach of the implied covenant of good faith and fair dealing, unfair
competition and declaratory relief.  The suit alleges that APP has breached a
distributorship agreement for certain Gensia Sicor Pharmaceuticals products by,
among other things, acquiring and operating a business which competes with
Gensia Sicor Pharmaceuticals with respect to some of the same products.  The
Company is seeking damages in excess of $10 million in addition to a declaration
that the Company has no obligation or liability to APP.

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS

     Gensia Sicor has been unprofitable on an annual basis since its inception
in 1986.  For the period from its inception to March 31, 1999, the Company has
incurred a cumulative net loss of $360.6 million.

     When used in this Form 10-Q, the words "expects", "anticipates",
"estimates" and similar expressions are intended to identify forward-looking
statements.  Such statements involve risks and uncertainties, including whether
new products will be timely developed, approved, and successfully marketed, the
impact of competitive products, product costs and pricing, changing market
conditions and other risks described in this Form 10-Q and in the Company's
Annual Report on Form 10-K for the year ended December 31, 1998.  Actual results
may differ materially from those projected.  These forward-looking statements
represent the Company's judgment only as of the date of the filing of this Form
10-Q.  The Company disclaims, however, any intent or obligation to update these
forward-looking statements.

RESULTS OF OPERATIONS

     The Company reported a net loss of $1.7 million, or $.02 per common share
(after dividends on preferred stock of $1.5 million), in the first quarter ended
March 31, 1999 compared to a net loss of $4.9 million, or $.06 per common share
(after dividends on preferred stock of $1.5 million), in the first quarter of
1998.

     Product sales in the first quarter of 1999 increased to $48.4 million from
$41.3 million in the first quarter of 1998.  The increase in product sales is
primarily due to increased sales in the international operations mainly from new
products.  International operations had a combined sales increase of $5.9
million over levels in the first quarter of 1998. Domestic product sales at
Gensia Sicor Pharmaceuticals also increased, mostly from the sale of inventory
to Abbott Laboratories as a result of the Sales and Distribution agreement
entered into with Abbott Laboratories in January 1999. One customer, the Mexican
hospital program, accounted for approximately $6.0 million of sales, or 13% of
the Company's sales in the quarter ended March 31, 1999.  No other international
customer accounted for more than 5% of the Company's sales in the three months
ended March 31, 1999.  Cost of sales for the first quarter of 1999 was $33.3
million which yielded a gross margin of 31%, compared to a cost of sales of
$28.1 million for the first quarter of 1998 which yielded a gross margin of 32%.

     Contract research and license fees in the first quarter of 1999 increased
to $5.3 million from $2.3 million in the first quarter of 1998.  The increase is
primarily due to a $3.5 million reimbursement from Baxter International for
Gensia Sicor Pharmaceuticals' expenses incurred for propofol research and
development. This increase was partially offset by a decrease in the license
revenue from Pfizer Inc. ("Pfizer"). The Company's 92% owned subsidiary,
Metabasis, continued to receive contract research revenues through its research
collaboration with Pfizer in the areas of pain and inflammation research and
with Sankyo Co. Ltd. in the area of diabetes. The research collaboration with
Pfizer will end in May 1999. Metabasis is engaged in discussions with other
pharmaceutical companies concerning collaborations under which these companies
would fund additional Metabasis' research and development efforts; however,
there is no assurance that any such collaborations will be completed.

     Research and development expenses in the first quarter of 1999 were $5.3
million compared to $5.2 million in the same period of 1998.  The Company is
continuing to pursue several options with respect to its Metabasis research
operation as the Company's strategic direction does not include a significant
commitment to basic research.  Such options could cause Metabasis' future
research and development expenses and contract research revenues to decrease
from current levels.

     Selling, general and administrative expenses in the first quarter of 1999
were $9.6 million compared to $9.7 

                                       9

                              GENSIA SICOR, INC.

million in the same period of 1998.
 
     The Company recorded amortization expense of $1.5 million in the first
quarter of 1999 compared to $1.4 million in the first quarter of 1998.  The
increase is due to the amortization of goodwill resulting from the acquisition
of the remaining 50% of Diaspa in June 1998 and the acquisition of a research
and development branch by the Company's subsidiary, Genchem Pharma, in March
1998.
 
     Interest and other expenses in the first quarter of 1999 increased to $2.6
million from $1.7 million in the first quarter of 1998 primarily due to higher
net interest expense from increased debt, and other expenses as a result of
Gensia Sicor Pharmaceuticals restructuring its sales force in connection with
its alliance with Abbott Laboratories.
 
     The Company elected in January 1998 to write down the investment value of
its 19% interest in Gensia Automedics, Inc. from $1.8 million to $0.7 million,
due to, among other things, the lack of market acceptance of the GenESA System.
Accordingly, the difference in investment balance of $1.1 million was reflected
as a current period charge to write-down of investment in the first quarter of
1998.  The Company subsequently wrote off the remaining balance of $0.7 million
in the fourth quarter of 1998.
 
     Income tax expense in the first quarter of 1999 was $1.5 million compared
to income tax expense of $17,000 in the first quarter of 1998.   The increase in
income tax expense is primarily attributable to increased earnings in the
foreign operations for the first quarter of 1999 compared to the first quarter
of 1998.
 
     The Company recorded minority interest income of $31,000 in the first
quarter of 1999 compared to $287,000 in the first quarter of 1998.   The
decrease is due to Diaspa, which became a wholly-owned subsidiary in June 1998
as a result of Sicor purchasing the remaining 50% interest in Diaspa.

LIQUIDITY AND CAPITAL RESOURCES

     As of March 31, 1999, Gensia Sicor had cash and cash equivalents of $25.2
million and working capital of $19.0 million compared to $24.5 million and $17.3
million, respectively, as of December 31, 1998.  The increase in cash and
working capital resulted from $9.5 million of cash provided by operations and
$0.7 million of cash from financing activities, offset by investment in long-
term assets of $8.2 million and $1.3 million of exchange rate changes.
 
     Significant changes in operating assets and liabilities during the first
quarter of 1999 included a $7.5 million increase in accounts payable and accrued
expenses, a $3.1 million increase in accounts receivable and a $0.6 million
decrease in prepaid expenses and other assets.  The increases in accounts
payable and accrued expenses and accounts receivable reflect the Company's
efforts to launch new products and complete transition with recent alliance
partners.
 
     In the first quarter of 1999, the Company paid cash dividends on its
preferred stock totaling $1.5 million.  At March 31, 1999, the Company had five
cumulative quarters, or approximately $7.5 million, in undeclared cumulative
preferred dividends.  If the Company chooses to not declare dividends for six
cumulative quarters, the holders of the preferred stock, voting separately as a
class, will be entitled to elect two additional directors until the dividend in
arrears has been paid.
 
     Gensia Sicor Pharmaceuticals entered into a Sales and Distribution
agreement with Abbott Laboratories in January 1999, under which the two
companies formed a strategic alliance for marketing and distribution of oncology
products in the United States.  In connection with this agreement, the Company
received $5.6 million in the first quarter of 1999.  Additionally, approximately
$5.0 million has been received in 1999 for the sale of inventory to Abbott
Laboratories.
 

                                       10
<PAGE>
 
                              GENSIA SICOR, INC.

     Gensia Sicor Pharmaceuticals also entered into an amendment to an earlier
agreement with Baxter International under which a fee of approximately $3.5
million was received in March 1999 from Baxter to reimburse Gensia Sicor
Pharmaceuticals for its expenses incurred for propofol research and development.

     The Company anticipates that its efforts to reduce overall costs and
expenses and working capital requirements, combined with its current cash and
cash equivalents on hand at March 31, 1999 of $25.2 million, and commitments
from third parties, will enable it to maintain its current and planned
operations through at least 1999.  In connection with its plans for expanding
its business, to accomplish its core strategy of being a leading fully-
integrated provider of injectable pharmaceutical products and services, the
Company's management and Board of Directors are evaluating plans to raise
required additional capital.  The Company will continue to evaluate the need for
additional capital and, if appropriate, pursue equity, debt and lease financing,
or a combination of these, for its capital needs.  Such financings may not be
available on acceptable terms, or at all.  If financing is not available, the
Company may have to reduce planned expenditures, discontinue certain operations,
or otherwise restructure to continue operations.
 
     As discussed in Note 5, the Company was named as a defendant in a complaint
filed by Protocol Systems.  The complaint alleges breach of the Supply
Agreement, and damages estimated at approximately $10.8 million, plus any
amounts which Protocol Systems may owe to a third-party vendor.  Gensia Sicor
believes that the amount of the claim is significantly overstated for a variety
of reasons and plans to vigorously defend itself against this claim.  Based on a
review of the current facts and circumstances, management has recorded a
provision for its estimate of liability related to this lawsuit.  The ultimate
outcome with respect to the lawsuit could have a material adverse effect on the
Company's financial position, results of operations or cash flows.
 
     Most of the Company's foreign subsidiaries use foreign exchange currency
contracts to reduce the negative financial impact of currency fluctuations.  In
March 1999, the Company's Italian subsidiary, Sicor, entered into twenty monthly
U.S. $1 million put options, ten at a strike price of Lira 1,696 per U.S. $1 and
an additional ten at a strike price of Lira 1,750 per U.S. $1.  As of March 31,
1999, no contracts have been exercised.
 
IMPACT OF YEAR 2000
 
     The Company has taken actions to understand the nature and extent of the
work required to make its systems and infrastructure Year 2000 compliant.
System hardware, software and microprocessor controlled equipment that support
the Company's infrastructure have been inventoried and assessed for Year 2000
compliance.  To the extent necessary to address material Year 2000 issues, the
Company is in the process of obtaining and installing current releases or
upgrades from software vendors.  All domestic business systems have been
upgraded and are believed to be compliant.

     Work continues on the Company's international facilities systems.  Upgrades
and conversions are scheduled for completion by the end of the second quarter of
1999 in Italy and by the end of the fourth quarter of 1999 in Mexico. A failure
by the Company to convert its international systems in a timely fashion could
have a material adverse effect on the Company.

     Because third party failures could have a material adverse impact on the
Company's ability to conduct business, the Company is attempting to obtain
written assurances from all material customers and vendors that their systems
are or will be Year 2000 compliant.  The Company has received such assurances
from its domestic material customers and vendors; however, this is an on-going
process.  The Company anticipates that this process will be completed by mid-
1999 for its international operations.  The Company's total sales to
international customers in the three months ended March 31, 1999 were
approximately $25.1 million, which represented approximately 52% of the
Company's total sales in such period.  The Mexican hospital program accounted
for approximately $6.0 million of the Company's sales in the quarter ended March
31, 1999.  If either the Company or any material customer or vendor 

                                       11

experiences a failure of any critical system, it could have a material adverse
impact on the Company's business or require the Company to incur unanticipated
expenses.
 
     If by mid-1999, the Company has not obtained reasonable assurances from
material vendors as to Year 2000 compliance, the Company will consider
alternatives, including the replacement of material vendors, if possible.  The
business interruption of any of the Company's significant customers, resulting
from their Year 2000 issues, could have a material adverse impact on the
Company's revenues and results of operations.
 
     The Company has not completed a formal contingency plan for non-compliance,
but it is developing a plan based on the information obtained from third parties
and an on-going evaluation of the Company's own systems.  The Company
anticipates having a contingency plan in place by mid-1999 which will include
development of backup procedures, identification of alternate suppliers and
possible increases in inventory levels.  The Company has not identified its most
reasonably likely worst case scenario with respect to possible losses in
connection with Year 2000 related problems.  The Company plans on completing
this analysis in mid-1999.

     There are many factors outside the Company's control that could cause the
Year 2000 problem to seriously disrupt its operations.  There are risks,
however, for which the Company is preparing and, in so doing, seeking to reduce
its exposure.  The scope of the Company's efforts regarding each risk is limited
to the Company's key products, key compounds, subsidiaries, critical suppliers,
and major customers.  The most critical of these risks are:  a disruption in
the supply of product with particular emphasis on failures of raw material
suppliers, commercial partners, and external distribution channels; internal
infrastructure failures such as utilities, communications, internal information
technology services and integrated information technology systems; 
government failures, especially as they impact import and export activity; 
interruption of the product regulatory filing process; and a major customer
failure or interruption.

     The cost incurred through March 31, 1999, for the Year 2000 transition was
approximately $1.0 million, which includes software and hardware upgrades that
would have been purchased in the normal course of business to accommodate future
growth and worldwide integration.  The Company estimates that the remaining
costs to be incurred on upgrading systems, including the Year 2000 transition,
will be approximately $1.0 million, and as such will not have a significant
impact on the Company's financial position or operating results.  Based on
available information, including assurances from software vendors that their
products are compliant, the Company believes that, barring critical failures
arising from factors beyond the Company's direct control, it will be able to
manage its total Year 2000 transition without any material adverse effect on its
business operations, products, operating results or financial condition.

               APPOINTMENT TO MARKET AND DISTRIBUTE THE PRODUCTS
                                        
     2.1   Exclusive Appointment.  Subject to the terms and conditions of this
           ---------------------                                              
Agreement, and except as set forth in Sections 2.2 and 8.2 hereof, Gensia Sicor
hereby appoints Abbott for the Term as Gensia Sicor's exclusive distributor of
the Products to the Trade in the Territory with the exception of the Products
identified in Exhibit 2.1 hereto, and Abbott hereby accepts such appointment. As
exclusive distributor, Abbott shall have the sole and exclusive right to
Promote, sell, and distribute the Products in the Territory for use by End Users
in the Territory.  Gensia Sicor hereby grants to Abbott, subject to Sections 2.2
and 8.2 hereof, the option to have the exclusive right to Promote, sell, and
distribute in the Territory for use by End Users in the Territory any product
which (a) Gensia Sicor develops, purchases, produces or acquires rights to
produce during the Term of this Agreement and (b) is approved by the FDA
pursuant to an ANDA filed by Gensia Sicor which references a Product as a
"listed drug."  This option shall be exercised by Abbott by written notice to
Gensia Sicor within thirty (30) days of the date of Gensia Sicor's written
notice to Abbott of the approval of the ANDA for such product by the FDA.  Any
product for which Abbott exercises such option shall be automatically added to
Exhibit 1.21 hereto as a New Product.

     2.2   Exception to Exclusive Appointment. Notwithstanding Section 2.1
           -----------------------------------                            
hereof, Abbott shall not be authorized to distribute, promote or sell the
Products to Premier Purchasing Partners, L.P. or its Affiliates, but may deliver
Product to Wholesalers.  At such time that Gensia Sicor's Manufacturing and
Distribution Agreement dated August 14, 1996, as amended, with American
Pharmaceutical Partners (the "APP Agreement") is terminated, Abbott's rights
hereunder shall become exclusive in the Territory.  Gensia Sicor will not extend
the term of the APP Agreement with respect to the Products nor add any
additional products to the APP Agreement except as required thereunder. Neither
Gensia Sicor nor Abbott will perform any action that would interfere with Gensia
Sicor's ability to meet its obligations under the APP Agreement.

     2.3   First Right of Negotiation for Product Line.  Except in the 
           -------------------------------------------
circumstances set forth in Section 21.2 hereof, in the event Gensia Sicor
decides to divest itself of its 

                                       6
<PAGE>
 
rights to produce, distribute and sell any of the Products, Abbott shall have
the first right to negotiate with Gensia Sicor to purchase all such rights which
Gensia Sicor has to such Products in accordance with the procedures set forth in
this Section 2.3.

     (a)  Gensia Sicor shall notify Abbott in writing of its decision to sell
its rights to any Product. For a period of up to thirty (30) days following
receipt of such written notification from Gensia Sicor, the Parties shall
negotiate in good faith regarding written terms and conditions upon which Abbott
would purchase such rights to such Product. If the Parties are able to reach
written agreement regarding the material terms and conditions of a sale of such
rights to such Product to Abbott within such thirty (30) day period, the Parties
shall negotiate in good faith for a period of up to sixty (60) days a definitive
agreement for the purchase of such rights by Abbott. Gensia Sicor shall not
negotiate with any Third Party regarding the sale of the rights to any Products
prior to completion of its negotiations with Abbott set forth in this Section
2.3(a).

     (b)  If the Parties are unable to agree upon written terms and conditions
with respect to such rights to a Product within thirty (30) days after Abbott's
receipt of the written notice from Gensia Sicor regarding the sale of such
rights to such Product or, having reached written agreement on the material
terms and conditions of such sale, are unable to negotiate a definitive
agreement for such sale within sixty (60) days after reaching written agreement
upon the terms and conditions of such sale, Gensia Sicor shall be free to
negotiate with Third Parties regarding a sale of such rights to such Product;
provided, however, that Gensia Sicor shall not sell the rights to such Product
- --------  -------                                                             
to a Third Party on terms which are in the aggregate less favorable to Gensia
Sicor, as reasonably determined by Gensia Sicor, than the terms Abbott offered
to Gensia Sicor pursuant to this section 2.3 unless Abbott  (i) withdraws such
offer or (ii) decides to not exercise its rights as set forth in this Section
2.3.

     (c)  The Parties agree that Gensia Sicor's sale of its rights to any
Product shall in no way affect Abbott's right and obligations hereunder, and any
such purchaser of the rights to any such Products shall assume all of Gensia
Sicor's obligations hereunder.

     2.4  Marketing Efforts.  During the Term, Abbott shall Promote, sell and
          -----------------                                                  
distribute the Products to the Trade in the Territory consistent with the manner
in which Abbott would Promote, sell and distribute products of comparable
commercial and medical significance which are developed, controlled, sold or
distributed by Abbott.  In furtherance of such efforts, Abbott shall employ its
expertise, best professional judgment and working relationships to ensure that
Abbott Promoters Promote the Products to maximize Product sales with each
Promotion thereof.  Such efforts shall be consistent with the Abbott Promoters'
overall responsibilities within the Abbott Hospital Products Division sales
force.  During the Term of this Agreement, Abbott will maintain a strategic
Oncology Market focus.  Abbott will maintain an oncology business unit which
dedicates resources reasonably required at all times to fulfilling the
commitments set forth in this Agreement, including without limitation, utilizing
no fewer than twenty (20) full-time equivalent employees (FTE's).  Abbott will
develop and update a short term and 

                                       7
<PAGE>
 
a five (5)-year business plan and deliver the same to Gensia Sicor, on an annual
basis at least thirty (30) days prior to the beginning of each Contract Year
commencing with Contract Year 2000, for the Promotion and sale of the Products.
Representatives of the Parties shall meet in person or by telephone at least
once each Calendar Quarter to discuss strategy, tactics for selling and sales of
the Products.

     2.5  Trade Costs.  Notwithstanding Section 1.17 hereof, Abbott shall be
          -----------                                                       
responsible, at its sole cost and expense, for payment of all Wholesaler
Reversals and Distributor Reversals, cash term discounts (e.g.; 2% 15, net
thirty (30)), management fees, rebates, service allowances, Performance
Incentives, credits, taxes, freight, shipping charges and other sales related
charges associated with Abbott's sales of the Products to the Trade.  Gensia
Sicor shall be responsible, at its sole cost and expense, for payment of all
Medicare/Medicaid Rebates as required by either federal or state-run programs.

     2.6  Selling Price.  Abbott shall determine, in its sole discretion, the 
          -------------
final sales price of the Products sold by Abbott to the Trade. Gensia Sicor
shall not refuse to sell Product to Abbott due to the final sales price at which
any Product is sold by Abbott to the Trade.

     2.7  Assignment and Assumption of Agreements.  Gensia Sicor hereby assigns
          ---------------------------------------  
to Abbott all of Gensia Sicor's right, title and interest to, and delegates to
Abbott all of Gensia Sicor's obligations to supply Products under, those certain
agreements relating to Gensia Sicor's sale of the Products prior to the
Effective Date that are listed within Exhibit 2.7  (collectively, the "Product
Agreements") for all agreements that can be assigned without prior approval by
the other party.  Gensia Sicor agrees to cooperate with Abbott and use
commercially reasonable efforts to attempt to secure required approvals to
assign any remaining agreements (which would, except for restrictions on
assignment, otherwise be deemed Product Agreements) within a reasonable time
after the Effective Date.  Gensia Sicor hereby represents to Abbott that, to
Gensia Sicor's knowledge, no party to any of the Product Agreements, as of the
Effective Date, is in material breach of the Product Agreements.  Abbott hereby
assumes all of Gensia Sicor's obligations under the Product Agreements as of the
Effective Date, and any additional agreements for which Third Party consents are
subsequently obtained (which shall then be deemed to be Product Agreements as of
such subsequent date), except for any obligations relating to free goods and
Performance Incentives in excess of *** of the invoiced sales amount of Products
to such customers as set forth in the Product Agreements.  Gensia Sicor shall
retain the obligations in this Section only for the current term of the Product
Agreements as of the Effective Date of this Agreement exclusive of any
extensions or renewals.  Abbott shall use commercially reasonable efforts to
remove Gensia Sicor's contractual obligations relating to free goods and
Performance Incentives as defined in this Section by December 31, 1999.  Gensia
Sicor will continue to service each End User that refuses to assign Product
Agreements to Abbott until such time alternate agreements can be reached between
the Parties and such End User.

Abbott and American Pharmaceutical Partners, L.P.  The Parties expressly agree
that nothing in this Section 2.8 shall restrict the ability of Gensia Sicor to
initiate commercial activities pursuant to Section 18.4(e).

     Price for each Product(NDC) for the following Contract Year.  At such
     meeting, Gensia Sicor and Abbott shall review the Gross Price for each
     Product(NDC) for the immediately preceding Calendar Quarter and the pricing
     trends and market dynamics which may affect the Gross Price of such
     Product(NDC) in the following Contract Year. Based on this information,

     Parties shall calculate *** percent (***%) of the estimated average Gross

     tenths (.8) to obtain the Transfer Price;

          (B)    If a Product(NDC) is a New Product not previously sold by
    Gensia Sicor, the calculation in Section 6.1(b)(ii)(A)(6) shall use (instead
    of the average Gross Price at which Abbott sold such Product(NDC)) (1)
    .9IP(y), for Class 1 New Products(NDC) and (2) IP(y), for Class 2 New
    Products(NDC); and

          (C)    Gensia Sicor shall deliver such calculation of the Transfer
     Price for each Product(NDC) to Abbott no later than December 15th of that
     Contract Year. In the event Gensia Sicor fails to deliver to Abbott such
     calculations by December 15th, Abbott shall make such calculations. The
     calculations of the Transfer Price for each Product(NDC) by Gensia Sicor or
     Abbott, as applicable, shall be binding absent manifest error.

          (iii)  Notwithstanding anything to the contrary contained in this
     Agreement, the Transfer Price for a Product(NDC) shall not be less than the
     Cost Threshold for that Product(NDC).

          (iv)   If any product for which a Transfer Price has not been
     determined shall be added to this Agreement as a Base Product or a New
     Product during a Contract Year, the Parties shall determine the Transfer
     Price therefor for the remainder of that Contact Year pursuant to this
     Section 6.1, provided that the references therein to the third Calendar
     Quarter shall be references to the Calendar Quarter ended prior to the date
     on which such product is added to this Agreement.

     6.2  Inventory Revaluation.  Abbott shall revalue the inventory of each
          ---------------------                                             
Product(NDC) at Abbott distribution centers and public warehouses as of close of
business on December 31/st/ of each Contract Year during the Term, by
multiplying (a) the number of units of such Product in Abbott's stock the shelf-
life for which has not expired on December 31st of such Contract Year by (b) the
Transfer Price of such Product(NDC) for the current Contract Year less the
Transfer Price for such Product(NDC) for the following Contract Year (determined
pursuant to Section 6.1 above). If the amount obtained from the calculation in
the foregoing sentence is positive, Gensia Sicor shall pay to Abbott 

                                       14

such amount, however; if the amount obtained from such calculation is negative,
Abbott shall pay to Gensia Sicor such amount. The Parties shall account for any
such revaluation in the first Calendar Quarter's reconciliation described in
Section 7.4 hereof.

     7.1  Abbott Compensation.
          ------------------- 

     (a)  Abbott's total compensation from Gensia Sicor for selling, marketing,
promoting and distributing the Products, and the activities associated
therewith, shall depend upon the extent to which the Gross Sales of the Products
are greater than, equal to or less than the Base Sales Level in a Contract Year,
subject to the following limitation:  ***

     (b) Abbott's compensation for its marketing, promoting, distributing and
selling of *** during a Calendar Quarter shall be, upon approval of the ANDA for
***, the "Margin Split Percentage" applicable to Abbott as set forth in Exhibit
7.1(b) times the following amount, calculated for that Calendar Quarter
("Margin"): (A) the Gross Sales of *** minus (B) the sum of (I) *** percent
(***%) of such Gross Sales and (II) the sum of (x) *** ($***) times the number
of finished dosage units of *** included in such Gross Sales and (y) *** ($***)
times the number of International Units of *** included in such Gross Sales.
Abbott shall, at the close of each Calendar Quarter calculate its compensation
under this Section 7.1(b) and Gensia Sicor's share of the Margin ("Gensia
Sicor's *** Share"), which is the Margin Split Percentage applicable to Gensia
Sicor as set forth in Exhibit 7.1(b) times the Margin.

     (c)  After the close of each Calendar Quarter, Abbott and Gensia Sicor
shall calculate the following for all Products, other than ***, for that
Calendar Quarter:

          (i) Gensia Sicor shall calculate for (x) the Products sold pursuant to
     the APP Agreement (the "APP Products"), (y) Doxorubicin and (z) all other
     Products (other than ***; the "Other Products") :

               (A)  an amount ("Aggregate Cost Threshold") equal to the Cost
          Threshold thereof times the number of units thereof included in the
          Gross Sales thereof in that Calendar Quarter; and

                 (B)  an amount ("Aggregate Revenue") equal to the Transfer
          Price thereof times the number of units thereof included in the Gross
          Sales thereof in that Calendar Quarter;

          (ii)   based on the information received from Gensia Sicor calculated
     pursuant to Section 7.1(c)(i), Abbott shall calculate for the APP Products:

          ("APP Compensation Amount"); and

                 (B)  the sum ("APP Amount") of the Aggregate Revenue of such
          APP Products plus the APP Compensation Amount;

          provided that (A) this Section 7.1(c)(ii) shall not apply to Gross
          Sales of APP Products in excess of (I) *** dollars ($***) in 1999 and
          (II) *** dollars ($***) in 2000;  (B) all calculations with respect to
          Gross Sales of APP Products above such amounts shall be made pursuant
          to Section 7.1(c)(iv); and (C) from and after the first full Calendar
          Quarter following the earlier of the termination of the APP Agreement
          or July 1, 2000, the calculations for the APP Products (other than
          Doxorubicin) shall be made pursuant to Section 7.1(c)(iv);

          (iii)  based on the information received from Gensia Sicor pursuant to
     Section 7.1(c)(i), Abbott shall calculate for Doxorubicin:

                 (A)  *** percent (***%) of the Gross Sales of Doxorubicin
          ("Doxorubicin Compensation Amount");

                 (B)  the sum ("Doxorubicin Amount") of the Aggregate Revenue of
          Doxorubicin included in the calculation of the Doxorubicin
          Compensation Amount and the Doxorubicin Compensation Amount; and

                 (C)  if an amount ("Doxorubicin Base Amount") equal to ***
          (***) of the Aggregate Cost Threshold of Doxorubicin is greater than
          the Gross Sales of Doxorubicin, an amount (the "Doxorubicin Limited
          Compensation Amount") equal to such Gross Sales minus such Aggregate
          Cost Threshold;

          provided that from and after the earlier of December 31, 1999 or the
          first full Calendar Quarter following approval of the Gensia Sicor
          site transfer supplement for Doxorubicin, the calculations for
          Doxorubicin shall be made pursuant to Section 7.1(c)(iv);

                 (B)  the sum ("Product Amount") for the Other Products of the
          Aggregate Revenue and the Product Compensation Amount; and

                 (C)  if an amount ("Product Base Amount") equal to *** percent
          (***%) of the Aggregate Cost Threshold of the Other Products is
          greater than the Gross Sales of the Other Products, an amount (the
          "Limited Compensation Amount") equal to such Gross Sales minus such
          Aggregate Cost Threshold;

          provided that the calculations made under this Section 7.1(c)(iv)
          shall not be made for (A) the APP Products until the calculations
          under Section 7.1(c)(ii) shall terminate as provided therein and (B)

Product(NDC) shall be determined as follows:

     (a)  Contract Year 1999.  For the Contract Year of 1999, the Base Sales
          ------------------                                                
Level for all Products shall be *** ($***), of which the detail for each
Product(NDC) is set forth in Exhibit 7.2 (a) hereto.

     (b)  Contract Years 2000 and Beyond. Concurrently with the setting of the
          ------------------------------                                      
Transfer Prices, which shall occur each October for the following Contract Year

Sales Level for each Product(NDC) for the following Contract Year as follows:

          (i)  Base Products:
               ------------- 

               (A)  In establishing the Base Sales Level for each class of Base
          Product by NDC ("Base Product(NDC)"), Abbott and Gensia Sicor shall
          review the previous twelve (12) months of unit sales for such
          Product(NDC) and based upon market conditions and opportunities adjust
          such sales to account for market unit growth or degradation to
          estimate the number of units of such Base Product(NDC) ("Unit
          Estimate") to be sold in the following Contract Year. The Unit
          Estimates shall not employ trends that exceed those derived from
          available IMS data unless the Parties mutually agree in writing to
          apply an alternative trend or agree in writing to use other

          reliable Third Party information. The Projected Gross Price for such
          Base Product(NDC) as determined by Section 6.1 hereof in connection
          with establishing the Transfer Price pursuant to Section 6.1 shall
          then be multiplied by the Unit Estimate for that Base Product(NDC) to
          calculate the Base Sales Level therefor.

               (B)  If the Parties have not determined the Unit Estimate for a
          Base Product(NDC) by November 30th, Gensia Sicor shall calculate the
          Unit Estimate for that Product(NDC) for the following Contract Year by
          (1) identifying the unit sales of such Product(NDC) as reported by IMS
          for the twelve months ending the third Calendar Quarter of the
          preceding Contract Year (such amount being hereinafter referred to as
          "IP(y-1)") and the unit sales of such Product(NDC) as reported by IMS
          for the twelve months ending the third Calendar Quarter of the
          Contract Year (such amount being referred to as "IP(y)") in which the
          calculation is made, (2) dividing IP(y) by IP(y-1), and (3)
          multiplying that result times the number of units of such Product(NDC)
          sold by Abbott during the preceding twelve (12) months ending
          September 30/th/ of that Contract Year.

               (C)  Any potential new Base Product(NDC) business that is
          anticipated from Premier Purchasing Partners, L.P. or Novation during
          the following Contract Year shall be presented as separate and
          distinct from Base Product business anticipated from the rest of the
          Trade for the sole purpose of determining purchase and manufacturing
          obligations of the Parties set forth in Section 10.1 hereof.

          (ii) New Products:
               ------------ 

               (A)  The Base Sales Level for each class of New Products by NDC
     ("New Product(NDC)") that is the first ANDA to market ("Class 1 New
     Product(NDC)"), shall be determined as follows:

               (I)  Gensia Sicor and Abbott shall utilize the most recent eight
          (8) quarters of IMS Hospital Unit Sales for that Product(NDC) and
          other IMS Unit Sales (the "IMS Non-Hospital Unit Sales") for that
          Product(NDC) multiplied by *** percent (***%) (or such other reliable
          Third Party information as the Parties may agree upon) trended to
          calculate the rate of change in unit sales of such Class 1 New
          Product(NDC), and to use such rate of change to calculate the current
          total available unit market for such Class 1 New Product(NDC). Based
          upon anticipated market conditions, a factor agreed upon by the
          Parties shall then be applied to account for unit growth or
          degradation to arrive at an annual unit estimate for the following
          Contract Year. A Projected Gross Price for Class 1 New Product(NDC),

          which shall be determined pursuant to Section 6.1 hereof in connection
          with establishing the Transfer Price pursuant to Section 6.1, will be
          multiplied by such annualized unit estimate to compute the anticipated
          total available dollar market for each Class 1 New Product(NDC). The
          Base Sales Level for each Class 1 New Product(NDC) will be calculated
          from such anticipated total available dollar market by assuming a ***
          percent (***%) market share gain per month in the first *** (***)
          months following commercial launch of such Class 1 New Product(NDC),
          *** percent (***%) market share gain per month for the next *** (***)
          months, and a *** percent (***%) market share gain per month for the
          next *** (***) months. Exhibit 7.2(b)(ii) attached hereto provides an
          example of how the Base Sales Level may be determined for a New
          Product(NDC).


               (II)   If the Parties have not agreed upon the Base Sales Level
          for a Class 1 New Product(NDC) by November 30/th/, Gensia Sicor shall
          calculate the Base Sales Level therefor by (1) identifying the unit
          sales of such Product(NDC) as reported by IMS for the twelve months
          ending the third Calendar Quarter two years prior to the third
          Calendar Quarter of the current Contract Year (such amount being
          hereinafter referred to as "IN(y-2)") and the unit sales of such
          Product(NDC) as reported by IMS for the twelve months ending the third
          Calendar Quarter of the Contract Year (such amount being referred to
          as "IN(y)") in which the calculation is made; (2) dividing IN(y) by
          IN(y-2); (3) multiplying that result times IN(y); (4) identifying the
          portions of the result obtained in the preceding clause (3) that are
          attributable to IMS Hospital Unit Sales and IMS Non-Hospital Unit
          Sales and multiplying the IMS Non-Hospital Unit Sales portion times
          1.10 and then adding that result to the IMS Hospital Unit Sales
          portion; (5) multiplying that amount by the applicable percentage
          provided in the last sentence of Section 7.2(b)(ii)(A)(I); and (6)
          multiplying that amount by the Projected Gross Price for that
          Product(NDC).

               (B)    Base Sales Levels for each New Product(NDC) that is not
          the first ANDA to market ("Class 2 New Product(NDC)") shall be
          determined as follows:

               (I)    Gensia Sicor and Abbott shall utilize the anticipated
          total available dollar market for each Class 2 New Product(NDC)
          calculated in the same manner as set forth above for Class 1 New
          Product(NDC), but assuming a *** percent (***%) market share gain per
          month in any *** (***) of the first *** (***) months following
          commercial launch of such Class 2 New Product(NDC). If fewer than ***
          percent (***%) of the GPO awards are available or become available
          within the first eighteen (18) months of the introduction of any Class
          2 New Product(NDC), then the Parties will meet to

          review the market share gain percentage assumptions set forth above,
          and shall use good faith efforts to agree on a new market share gain
          percentage schedule that reflects the true market opportunity for such
          Class 2 New Product(NDC).

               (II) If the Parties have not agreed upon the Base Sales Level for
          a Class 2 New Product(NDC) by November 30/th/, Gensia Sicor shall
          calculate the Base Sales Level therefor by making the same
          calculations for that Product(NDC) as are made in Sections
          7.2(b)(ii)(A)(II)(1), (2), (3) and (4) and multiplying that amount by
          the applicable percentage provided in the first sentence of Section
          7.2(b)(ii)(B)(I), and then multiplying that amount by the Projected
          Gross Price for that Product(NDC).

               (C)  Twenty-four (24) months following commercial launch of any
          Class 1 or Class 2 New Product(NDC), such New Product(NDC) will be
          treated as a Base Product(NDC), and the Base Sales Level with respect
          to such Base Product(NDC) will be calculated in accordance with the
          provisions of Subsection 7.2(b)(i) hereof.

     (c)  Calculations.   Gensia Sicor shall deliver such calculation of the
          ------------                                                       
Base Sales Level for each Product(NDC) to Abbott no later than December 15/th/
of that Contract Year. In the event Gensia Sicor fails to deliver to Abbott such
calculations by December 15/th/, Abbott shall make such calculations. The
calculations of the Base Sales Level for each Product(NDC) by Gensia Sicor or
Abbott, as applicable, shall be binding absent manifest error.

     (d)  Adjustments to Base Sales Levels.  If during any Contract Year a
          --------------------------------                                
product for which a Base Sales Level has not been calculated becomes a Base
Product or a New Product, the Parties shall calculate the Base Sales Level for
such product for the remainder of the Contract Year following Section 7.2(b)(i)
or (ii), as applicable, provided that references to the Calendar Quarter therein
shall be to the Calendar Quarter most recently ended. If any Base Product(NDC)
or New Product(NDC) shall be deleted from this Agreement, the Parties shall
reduce the Base Sales Level for that Product(NDC) for the remainder of the
Contract Year by subtracting from such Base Sales Level an amount equal to the
product of (x) the number of days remaining in that Contract Year divided by 365
or 366, as the case may be, and (y) the Base Sales Level for that Product(NDC)
for that Contract Year.
 
     7.3  Unforeseen Market Conditions.  Adjustments to the Base Sales Level may
          -----------------------------   
be made by written agreement of the Parties in the event of unforeseen market
conditions such as Product unavailability, delay in a Product's launch, and the
launch of a new product which erodes the total available market for a Product.
 
     7.4  Reconciliation.
          -------------- 

                                       24
<PAGE>
 
     (a)  During the Term, Abbott shall perform a quarterly reconciliation
following the end of each Calendar Quarter (i) to determine the amount of any
payments to be made pursuant to Section 7.1 hereof for such Calendar Quarter,
(ii) to report inventory balances of each Product and (iii) to take into account
any inventory revaluation required by Section 6.2 hereof. Abbott shall prepare a
written reconciliation for each Product for a Calendar Quarter.

     (b)  Abbott shall perform an annual reconciliation following the end of
each Contract Year to determine the amount of any payment to be made pursuant to
Section 7.1 hereof. Abbott shall prepare a reconciliation for each Product(NDC),
indicating the Gross Sales, average Gross Price, Base Sales Level and inventory
balances for each Product(NDC).

     (c)  Abbott shall submit such written reconciliation reports to Gensia
Sicor within forty-five (45) days after the end of the Calendar Quarter or
Contract Year, as applicable, and such reports shall contain sufficient detail
and information to enable Gensia Sicor to ascertain their accuracy. Gensia Sicor
shall review and approve or request modification, in writing, of such
reconciliation report with fifteen (15) business days of receipt by Gensia
Sicor. If Gensia Sicor does not request modification within such fifteen (15)
business day period, the reconciliation report will be deemed to have been
approved by Gensia Sicor. Adjustments as to overpayments or underpayments, if
any, based on such reconciliation report shall be made by the affected Party to
the other Party within forty-five (45) days after Gensia Sicor's receipt of such
reconciliation report.

     7.5  Trigger Cost.  In October of each Contract Year Gensia Sicor shall set
          ------------                                                      
a dollar amount (the "Trigger Cost") for each Product for the following Contract
Year. Gensia Sicor may change such Trigger Cost from time to time during a
Contract Year at its sole discretion. When the difference between the weighted
average Gross Price and the Trigger Cost for a Product(NDC) is less than ***
percent (***%), Abbott will contact Gensia Sicor to discuss this situation and
Gensia Sicor shall agree to decrease the Trigger Cost to a level deemed
appropriate by Gensia Sicor; provided, however, Gensia Sicor shall not be
                             --------  -------                           
compelled to decrease the Trigger Cost to a level less than Gensia Sicor's Cost
Threshold.  When the Trigger Cost for a Product(NDC) is within one hundred fifty
percent (150%) of the Cost Threshold for that Product(NDC), Gensia Sicor will
inform Abbott of such in writing and the Parties shall meet within sixty (60)
days to discuss what actions should be taken with respect to such Product(NDC).

     7.6  Deletion of Products.  In the event that the Gross Sales minus the
          --------------------                                              
Cost Threshold for any Product(NDC) is less than Abbott's variable costs for
distributing, selling and marketing such Product(NDC), Abbott may delete such
Product(NDC) from this Agreement upon ninety (90) days prior written notice to
Gensia Sicor, subject to Section 12.3(d).

(the "First Sales Date") shall be deemed to be the date on which sales of the
Products, whether by Gensia Sicor or Abbott, begin to be counted as Gross Sales
for Contract Year 1999.

     8.2  Inventory Transition.
          -------------------- 

     (a)  On or before January 31, 1999, the Parties shall use commercially
reasonable efforts to complete an inventory assessment of all Products held by
Wholesalers and Distributors as of the Effective Date; the results of such
inventory assessment shall be used to determine appropriate Wholesaler Reversal
or Distributor Reversal and Return adjustments as described in Sections 8.3 and
8.4 hereof.

     (b)  Abbott, for its sole account, shall pay for all costs and expenses,
including, without limitation transportation costs, costs associated with
conducting the inventory assessment described in the preceding sentence and
costs of acquiring inventory located at Gensia Sicor's distribution warehouses.

     (c)  Notwithstanding anything to the contrary contained in Section 2.1, the
Parties acknowledge that Gensia Sicor has sold Products before the date of this
Agreement and the Parties agree that Gensia Sicor shall have the right to sell
the Products to the Trade in the Territory for use by End Users in the Territory
during the transition period (the "Transition Period") commencing on the First
Sales Date and terminating on a date (the "Transition Date") forty-five (45)
days after the Effective Date. All sales during the Transition Period shall be
credited to Abbott in accordance with Section 8.1 hereof. On or before the
Transition Date, Abbott shall purchase and Gensia Sicor shall sell to Abbott all
of Gensia Sicor's inventory of the Products as of the Effective Date at the
Transfer Price for such Products, except for such quantity of Products as
reasonably determined by Gensia Sicor to be desirable to meet Gensia Sicor's
contract obligations during the Transition Period.

     8.3  Wholesaler and Distributor Reversal Adjustment.  Abbott hereby assumes
          ----------------------------------------------                        
Gensia Sicor's liability for all Wholesaler Reversals and Distributor Reversals
for Products Gensia Sicor sold to Wholesalers and Distributors prior to the
First Sales Date and during the Transition Period.  As compensation for Abbott's
assuming, such Wholesaler Reversal and Distributor Reversal liability for
Products Gensia Sicor sold to such Wholesalers and Distributors prior to the
First Sales Date, Gensia Sicor shall pay to Abbott (within sixty (60) days after
the Parties complete the inventory assessment described in Section 8.2 hereof)
the actual amount of Wholesaler Reversals and Distributor Reversals paid by
Abbott to the Wholesalers and Distributors, on an aggregate basis,  with respect
to Products sold by Gensia Sicor prior to the First Sales Date.  In the event
that not all Product inventory, as determined per Section 8.2 above, is sold
sixty (60) days after the First Sales Date, Gensia Sicor shall pay to Abbott the
actual amount of 

                                       26
<PAGE>
 
Wholesaler Reversals and Distributor Reversals paid by Abbott to the Wholesalers
and Distributors on sales of this remaining inventory at the end of each
subsequent calendar month.

          In the event Gensia Sicor elects or is requested by Abbott to issue a
credit to Wholesalers and Distributors for Wholesaler Reversals or Distributor
Reversals with respect to Products sold by Gensia Sicor prior to the First Sales
Date, Gensia Sicor will be entitled to offset the amount of any such credit
against its liability to Abbott for the Wholesaler Reversals and Distributor
Reversals calculated pursuant to the preceding paragraph.

     8.4  Returns for Sales Prior to First Sales Date. As set forth in Section
          -------------------------------------------                         
12.3, Gensia Sicor shall retain the financial responsibility for Returns of
Products sold by Gensia Sicor prior to the First Sales Date.  Abbott shall track
all sales of Products by lot number. Gensia Sicor shall reimburse Abbott for any
Returns of Products processed by Abbott in accordance with Section 12.3 hereof,
but which relate to lot numbers of such Products sold by Gensia Sicor prior to
the First Sales Date.  Abbott shall issue a report detailing any such Returns
and within forty-five (45) days' receipt of the report, Gensia Sicor shall issue
a credit memorandum in the amount of such reimbursement to Abbott.  In the event
both Gensia Sicor and Abbott sold Products from the same lot, Abbott shall be
responsible, in accordance with Section 12.3 hereof, for Abbott's prorated share
of such Returns based upon the total units produced within such lot's production
run divided into the total number of units Abbott sold of such lot and Gensia
Sicor sold of such lot during the Transition Period.

     8.5  Doxorubicin Purchase Order.  Abbott shall place a purchase order for
          --------------------------                                          
the initial order of Doxorubicin within five (5) business days of the Effective
Date.  Abbott shall pay One Million Five Hundred Thousand Dollars (US$1.5
million) of such purchase order within ten (10) business days of the date such
purchase order was placed.   The remainder of the payment for the order will be
processed in accordance with Section 21.3 hereof.

     8.6  Accrued Rebates. Gensia Sicor shall remain liable to pay all 
          ---------------                                             
Performance Incentives and GPO management fees that have been earned but not yet
paid prior to the First Sales Date.

     9.1  Sales Report.  On or before the tenth day of each month, Abbott shall
          ------------                                                   
provide a report to Gensia Sicor reflecting the Gross Sales of the Products for
the prior month. Each such report shall provide, for each of the Products(NDC),
the Gross Price and the Gross Sales dollars and total unit sales for the
reported month and the year to date. An example of the Abbott monthly report is
set forth on Exhibit 9.1. The format of the monthly report shall be reasonably
acceptable to Gensia Sicor. In addition to hard copy summary reports, Abbott
shall supply to Gensia Sicor, in an electronic format reasonably acceptable to
Gensia Sicor, specific monthly Gross Sales detailed by End-Users, Returns,
Wholesaler Reversals, Distributor Reversals, contract and NDC number.

     9.2  Certificate of Analysis.  Upon Abbott's reasonable request, Gensia 
          -----------------------                                    
Sicor shall provide Abbott with a certificate of analysis with respect to a
shipment of the Products sold to Abbott hereunder.

     9.3  Inspection and Analysis.  All Products sold to Abbott hereunder shall
          -----------------------                                        
be subject to Abbott's inspection and approval. Abbott shall have the right, for
a period of thirty (30) days following its receipt of the Products, to reject
any Product which is:

     (a)  not in compliance with the Specifications;

     (b)  not in compliance with all manufacturing procedures, in-process
controls, testing, specifications, containers and storage conditions, as set
forth in Gensia Sicor's NDA for the Product, or any subsequent amendments
thereto;

     (c)  not manufactured in accordance with cGMPs;

     (d)  not conforming to instructions agreed upon by the Parties in writing
regarding shipment packaging or transport;

     (e)  not conforming to reasonable instructions regarding quantities and
configuration set forth in the purchase order form;

     (f)  shipped in violation of any applicable statute, administrative order
or regulation; or

     (g)  recalled by any governmental agency or by Gensia Sicor for a reason
not the fault of Abbott.

     If Abbott rejects any Product, it shall give Gensia Sicor written notice of
such rejection within the thirty (30) day evaluation period described above,
accompanied by a written summary of the grounds for rejection. Upon receipt of
such notice, Gensia Sicor may request Abbott to return the rejected Product, or
samples thereof, for testing by 

                                       28

Gensia Sicor.  Abbott's rejection shall be final unless Gensia Sicor notifies
Abbott in writing within thirty (30) days after the later of its receipt of the
rejection notice or the rejected Product, or samples thereof, that Gensia Sicor
disagrees with Abbott's conclusions with respect to the rejected Product. If the
Parties are unable to resolve the dispute, samples of the rejected Product shall
be submitted to a mutually acceptable independent testing laboratory for
analysis. The results of the independent testing laboratory shall be final and
binding on the Parties. The costs of the independent testing laboratory shall be
paid by the Party against whom the dispute is resolved. In the event the test
results indicate that the Products was properly rejected by Abbott, Gensia Sicor
shall replace such Product at Gensia Sicor's expense, including all additional
shipping and transportation costs, within twenty (20) business days if
replacement Product stock is available, or, if no such replacement stock is
available, as soon as is reasonably practical, after receipt of such results. In
the event the test results indicate that the Product was not properly rejected
by Abbott, Abbott shall pay all additional shipping and transportation costs
incurred as a result of the dispute.

least ten (10) days prior to the first day of each succeeding calendar month
during the Term, Abbott shall submit to Gensia Sicor a written rolling forecast
(a "Twelve Month Forecast") estimating by month Abbott's purchase requirements
for the Products, by NDC, for the following twelve (12)-month period.  The
first, second and third months of a Twelve Month Forecast represent a firm order
(a "Three Month Firm Order") for the Products and shall be accompanied by a
purchase order.  Upon receipt of a new Twelve Month Forecast, the fourth month
of the prior Twelve Month Forecast shall become a firm order as the third month
of the current Twelve Month Forecast.  Abbott shall be obligated to purchase at
least *** percent (***%) of the Twelve Month Forecast.  Gensia Sicor shall not
be obligated to supply for each of the three months following any Three Month
Firm Order more than *** percent (***%) of the quantity forecasted for each of
such months.  Such rolling twelve (12) month forecasts shall be used by the
Parties for planning purposes and shall not be binding on Abbott, except as set
forth in this Section 10.1.  At each time the Base Sales Level for the following
year is established, pursuant to Section 7.2 hereof, Abbott shall submit a new
Twelve Month Forecast for the following year for the same number of units used
to calculate such Base Sales Level, which shall be subject to the restrictions
described in the preceding sentences.  Abbott shall provide Gensia Sicor with a
five (5) year strategic forecast for the Products on an annual basis at the same
time it provides the five (5) year business plan provided pursuant to Section
2.4 hereof.  Unless otherwise specified in writing by Gensia Sicor to Abbott,
all forecasts shall be sent by Abbott to the following address:

                 DISTRIBUTION, BILLING, COLLECTION AND RETURNS
                                        
     12.1  Distribution.  Abbott shall be responsible, at its sole expense, for
           ------------                                                    
all distribution of the Products to the Trade in the Territory.

     12.2  Billing and Collection.  Abbott shall perform, at its sole expense, 
           ----------------------                                    
all invoicing and collection of payment for sales of the Products to the Trade,
including the processing of Wholesaler Reversals and Distributor Reversals, in a
manner consistent with its own standard billing system.
 
     12.3  Returns.  During the Term, Abbott shall be responsible for receiving
           -------                                                             
and issuing credits to the Trade for Returns of the Products.  Abbott shall use
its commercially reasonable efforts to manage inventory shipped to the Trade on
a first in,

first out basis in order to maximize the dating of Products held in inventory.
Abbott shall provide Gensia Sicor with an inventory status report by Product and
by lot number once each Calendar Quarter.

     (a)  Products returned to Abbott from the Trade or returned directly by the
Trade to Gensia Sicor shall be processed in accordance with Abbott's then
current return goods policy or a returned goods policy agreed to jointly by the
Parties (a current copy of which is set forth in Exhibit 12.3 hereto), which may
be modified by mutual written agreement of the Parties from time to time, and in
conformity with cGMPs and any controlling regulations in the Territory. In the
event a revised Abbott return goods policy results in Returns that exceed levels
recorded in the most recent Contract Year, Gensia Sicor shall not be obligated
to assume the financial liability for such increased Returns. The accounting for
Returns to Abbott or Gensia Sicor from the Trade that are re-sellable (as
determined in accordance with Gensia Sicor's then current quality assurance
guidelines) shall be as follows: (1) all Gross Sales credited to the Trade for
such Returns shall be deducted from the aggregate of Gross Sales of such
Products during the Calendar Quarter in which such Returns were processed and
(2) returned Product shall be restored to sellable stock. The accounting for
Returns to Abbott or Gensia Sicor from the Trade that are not re-sellable (as
determined in accordance with Gensia Sicor's then current quality assurance
guidelines) shall be as follows: (1) all Gross Sales credited to the Trade shall
be deducted from the aggregate of Gross Sales of the Products during the
Calendar Quarter in which the Return was processed; (2) Returns shall be shipped
to Gensia Sicor's designated site for proper disposal; (3) a credit for such
Returns shall be given by Gensia Sicor to Abbott in the form of a credit
memorandum issued by Gensia Sicor. Gensia Sicor shall issue the credit
memorandum for Returns described in this Section 12.3 at a per unit value equal
to the Transfer Price for such unit of Product sold by Abbott or if such Product
was sold by Abbott in a lot with respect to which more than one sale occurred
under different Transfer Prices as determined by the lot number for such
Product, the weighted average of such Transfer Prices will be used for the per
unit value of such unit of Product. Such "weighted average" shall be calculated
by dividing (i) the sum of the results obtained by multiplying, for each unit of
Product sold at a different Transfer Price, (A) the total number of units of
Product sold at a particular Transfer Price by (B) the Transfer Price at which
such units of Product were sold, by (ii) the total number of units of such
Product sold.

     (b)  Notwithstanding anything to the contrary contained in this Agreement,
Returns to Abbott or Gensia Sicor shall not be accepted for credit from
Distributors, but may be accepted for no credit and processed in conformity with
cGMPs and any other applicable governmental regulations.

     (c)  Product may not be returned from Abbott inventory to Gensia Sicor.
With respect to the final Contract Year, the Parties shall negotiate in good
faith sixty (60) days prior to the commencement of such final Contract Year,
appropriate terms, conditions, and procedures which shall enable Abbott to
return Product and receive either a credit or cash payment.

                                       31

     (d)  The Parties acknowledge the potential exists under this Section 12.3
for Abbott to ship excessive quantities of Product to Wholesalers, Distributors
or End Users in order to receive credit for Returns of excess inventory.  Abbott
acknowledges and agrees that such activity is expressly prohibited by this
Agreement, and agrees that it is responsible for the ultimate legitimate sale or
disposition of any inventory in Abbott's possession.   Moreover, Abbott
covenants to act responsibly with respect to the management of Returns.  Gensia
Sicor's obligation to reimburse Abbott for Returns which may not be restocked
and resold shall be limited by the percentage of all Product sales hereunder as
defined in the following table:

 Contract Year      Return Percent
- -----------------------------------
1                       ***%
- -----------------------------------
2                       ***%
- -----------------------------------
3 and beyond            ***%
- -----------------------------------

In any given Contract Year, if the dollar amount of Returns of all Products sold
hereunder when expressed as a percentage of the total dollar amount of sales of
all Products by Abbott exceeds the percentage set forth in the table above for
such Contract Year, Abbott shall pay to Gensia Sicor, within thirty (30) days
after the receipt of an invoice therefor, the fully burdened manufacturing
costs, as used by Gensia Sicor for its financial reporting purposes, for the
quantity of Product which must be destroyed plus reasonable out of pocket
expenses incurred by Gensia Sicor or its agents or contractors (such as third
party waste management companies) to destroy such quantity of  Product for the
incremental Returns of such Product in excess of that defined in the table
above; provided, however, that in the event the Returns exceed the applicable
       --------  -------                                                     
percentage set forth in the table above for reasons beyond Abbott's reasonable
control (e.g., Product defect or contamination), Abbott shall have no financial
responsibility for such Excess Returns.  Examples of activities that are within
Abbott's reasonable control, and therefore, Abbott will be accountable in the
event of such returns, are loading an End User, Wholesaler, or Distributor well
over their reasonable level of consumption in an attempt to artificially
increase  sales;  shipping errors where product cannot be restocked for resale;
and efforts to move short-dated inventory to the Trade, in the event this
inventory arrived at Abbott with sufficient dating as specified in Section 5.1
(c). In the event the dollar amount of Returns of Product sold when expressed as
a percentage of the total dollar amount of sales of that Product by Abbott
exceed the applicable percentage set forth in the table above the Parties, shall
be obligated to meet and identify the cause for such level of Returns and
jointly develop an action plan to lower the Return level.  If the dollar amount
of Returns of Product sold when expressed as a percentage of the total dollar
amount of sales of that Product by Abbott exceed the applicable percentage set
forth in the table above for any Product for two (2) consecutive Calendar
Quarters, Abbott may upon ninety (90) days' written notice to Gensia Sicor, at
its sole discretion, delete any such Product from the Agreement. Should Abbott
exercise a Product deletion under this

Section 12.3, Section 7.6 or Section 18.4 (a) or (b), Abbott shall use
commercially reasonable efforts to effect a smooth transition of such Product to
enable Gensia Sicor to promote the sale of such Products to the Trade; and
Abbott may not acquire or replace from a source other than Gensia Sicor,
develop, manufacture or have manufactured a deleted Product, other than by or
from Gensia Sicor, during the Term, unless the reason for deleting such Product
was primarily a result of Abbott's inability to service the Trade due to the
Cost Threshold for that Product set by Gensia Sicor; provided that Abbott may
replace a deleted Product from a source other than Gensia Sicor only if such
source offers Abbott terms and conditions materially better than those herein.

concerning the Products shall be the sole responsibility of Gensia Sicor. Abbott
shall assist Gensia Sicor with respect to communications from governmental
agencies regarding the Products to the extent deemed reasonably necessary by
Gensia Sicor to fully respond to such communications. Abbott shall not recommend
or knowingly sell the Products for any use except as described in the FDA
approved Product labeling.

     13.3  Medical and Technical Complaints. Gensia Sicor shall retain exclusive

responsibility for handling Product manufacturing and medical and technical
complaints and disputes with the FDA, physicians and patients, including timely
filing with the FDA all fifteen (15) day and periodic reportable adverse drug
experience ("ADE") reports. With respect to such reports and other
communications described in this Section 13.3, each Party shall appoint a
primary liaison ("Liaison") with whom the other Party is to communicate. Abbott
shall report to Gensia Sicor's Liaison within twenty-four (24) hours any ADE
report it receives or otherwise obtains in the Territory with respect to the
Products, and shall cooperate with Gensia Sicor in providing information,
including follow-up information, about such reports. Further, Abbott shall
direct to Gensia Sicor's Liaison within three (3) business days of receipt all
inquiries Abbott receives which relate to the efficacy, safety or other medical
issues regarding the Products, unless such inquiry is of a routine nature and
the response is clearly set forth in either the Product labeling or the Product
inquiry report supplied by Gensia Sicor to Abbott. The Product inquiry report
shall set forth the standard responses used by Gensia Sicor to respond to
questions of a routine nature directed to Gensia Sicor with respect to the
Product. Gensia Sicor shall supply the Product inquiry reports to Abbott's
Liaison within a reasonable time after the Effective Date.

disputes with customers and customer related activities with respect to the
Product, other than those described in Section 13.3, subject to the provisions
of Article 16 and Section 13.5.

recall or withdrawal or (iii) Gensia Sicor determines, after consultation with
Abbott, that a recall or withdrawal is necessary or advisable (each a "Recall"),
Gensia Sicor shall, at Gensia Sicor's sole cost and expense, conduct any Recall,
unless the Recall was caused by the storage, distribution or handling of the
recalled Product by Abbott or its Affiliates or by the negligence or willful
misconduct of Abbott or its Affiliates with respect to the Product.  In the
event the Recall was caused by Abbott as described above, Abbott promptly shall
reimburse Gensia Sicor for all direct costs of the Recall upon submission to
Abbott by Gensia Sicor of an itemized statement thereof.  For purposes of this
Section 13.5, "negligence" by Abbott or its Affiliates shall include, to the
extent the Product Recall was caused by advertising or promotional materials,
the preparation and use of advertising or promotional materials, unless such
materials were created by Gensia Sicor.  Each Party shall cooperate fully with
the handling of any Recall, including, without limitation, the contacting of End
Users of the Product, the taking of all appropriate corrective actions and the
conduct of any investigation surrounding the Recall.  For purposes of this
Section 13.5, the expenses of Recall shall include, but not be limited to, the
expenses of notification and destruction or Return of the recalled Product and
all other costs incurred in connection with such Recall, but shall not include
lost profits or any other indirect or consequential damages of either Party.

During the Term and for a period of three (3) years thereafter, upon thirty (30)

confidentiality agreement and shall report to Gensia Sicor only the amount and
relevant details of any discrepancy in the calculations. Within thirty (30) days
after completion of such examination, the Parties shall reconcile any
underpayment or overcharge. Such audit rights may be exercised by Gensia Sicor
only with respect to records for the previous thirty-six (36) months in which
Gross Sales occurred. Notwithstanding anything in this Section 14.1 to the
contrary, if a discrepancy to Gensia Sicor's detriment in excess of five percent
(5%) of the previous twelve (12) month's Gross Sales is detected during an audit
performed pursuant to this Section 14.1, then Abbott shall bear the costs of

retain and keep any and all sums received, obtained, collected or recovered
whether by judgment, settlement or otherwise, as a result of such suit or
action.  Abbott shall, at Gensia Sicor's expense, render all reasonably
requested assistance in any such suit or action, including, but not limited to,
joining or being named in such suit or action, executing all required documents
and providing records, data and company witnesses.  In the event that Gensia
Sicor elects not to enforce any Patent against such infringer within ninety (90)
days after receipt of notice of such infringement, then Gensia Sicor shall
notify Abbott of its decision not to enforce the Patent against such infringer,
and Abbott shall have the right, but not the obligation, to do so, at Abbott's
sole expense, and shall be entitled to retain and keep any and all sums
received, obtained, collected or recovered whether by judgment, settlement or
otherwise, as a result of such suit or action.  Gensia Sicor shall, at Abbott's
expense, render all reasonable requested assistance in any such suit or action,

continue automatically for successive one (1) year periods unless either party
provides written notice of termination to the other party three (3) years prior

Agreement upon the end of the seventh Contract Year must give written notice of
termination to the other party prior to the beginning of the fifth Contract
Year.

make a general assignment for the benefit of creditors and such proceeding or
assignment has not been dismissed or discharged within thirty (30) days
thereafter; or (c) any bankruptcy, reorganization, debt arrangement, or other
case or proceeding under any bankruptcy or insolvency law, or any dissolution or

furtherance of, any of the foregoing; or (e) materially breaches this Agreement
and fails to cure such breach within sixty (60) days after receipt of written
notice of such breach from the non-breaching party.

     18.3  By Abbott for Gensia Sicor's Inability to Supply. In the event Gensia
           ------------------------------------------------   
Sicor is unable to supply a Product to Abbott hereunder for reason of Force
Majeure, as described in Section 20.1, or a Product Recall or withdrawal, for a
period of at least one hundred eighty (180) consecutive days, Abbott shall have
the right to terminate this Agreement with respect to such Product, if Gensia
Sicor fails to cure such inability to supply within thirty (30) days after
receipt of written notice from Abbott regarding such inability.

     18.4  By Gensia Sicor for Lack of Abbott Performance.
           ---------------------------------------------- 

     (a)   If the Gross Sales for all Products for a Contract Year are less than
*** percent (***%) of the Base Level Sales for all Products for that Contract
Year, Abbott shall, at the request of Gensia Sicor, meet from time to time, in
person, with Gensia Sicor to discuss the reasons for such performance by Abbott
and use commercially reasonable efforts to agree upon a plan calculated by the
Parties to increase the sales of Products for the following years; provided,
                                                                   --------
however, that this subsection (a) shall not apply in any case where subsection
- -------                                    
(b) shall apply.

     (b)   If:

     (x)   the Gross Sales for all Products for 1999 are less than *** dollars
           ($***),

     (y)   the Gross Sales for all Products for a Contract Year are less than
           *** percent (***%) of the Base Level Sales for all Products for that
           Contract Year, or

     (z)  (I) the Gross Sales for all Products for a Contract Year are less than
          *** percent (***%) of the Base Level Sales for all Products for that
          Contract Year and (II) Gensia Sicor shall have notified in writing
          Abbott within ninety (90) days of the end of the prior Contract Year
          in which, during the Term the Gross Sales for all Products for such
          prior Contract Year were less than *** percent (***%) of the Base
          Level Sales for all Products for that Contract Year,

then (i) upon written notice by Gensia Sicor to Abbott within ninety (90) days
of the end of a Contract Year, the Parties shall negotiate in good faith
modification or replacement of any and all terms of this Agreement as proposed
by Abbott in response to such notice and (ii) upon further written notice by
Gensia Sicor to Abbott, unless the Parties shall have executed an amendment or
new agreement setting forth terms and conditions agreed by the Parties pursuant
to preceding clause (i) within sixty (60) days of the notice given pursuant
thereto, this Agreement shall terminate on the date set forth in the notice
given pursuant to this clause (ii); provided, however, that in calculating the
                                    --------  -------                         
Gross Sales achieved by Abbott in a Contract Year for purposes of determining
whether an event described in clause (x), (y) or (z) has occurred, Abbott shall
be deemed to have attained those Gross Sales which Abbott would have attained
had Gensia Sicor delivered Products which it failed to deliver as a result of a
breach by Gensia Sicor or a Force Majeure.

     (c)  If Gensia Sicor terminates this Agreement pursuant to clause (x) in
subsection (b) of this Section 18.4, Abbott shall, within 30 days of such
termination, repay to Gensia Sicor all amounts received by it pursuant to
Articles 6 and 7 of this Agreement.

     (d)  Upon termination of the Agreement pursuant to 18.4 (c), Abbott shall
use its best efforts to effect a smooth transition of the promotion, sale and
distribution of the Products to the Trade by Abbott to Gensia Sicor. At its sole
option, Gensia Sicor may purchase from Abbott all or any portion of Abbott's
supply of any Product at the Transfer Price for such Product. In the event
Gensia Sicor does not elect to buy back Abbott's inventory for any Product,
Abbott shall be allowed to sell such inventory of such Product to the Trade in
the Territory for use by End Users in the Territory.

     (e)  Within one hundred eighty (180) days prior to termination of this
Agreement, Gensia Sicor shall have the right to initiate commercial activities
which may include contracting, establishing customer relationships or other
activities directed toward sales activities which will begin upon the effective
date of termination; provided, however, that Gensia Sicor covenants that none of
                     --------  -------                                          
its activities during such period will unreasonably interfere with Abbott's
ability to achieve Abbott's Base Sales Level.

cause as rapidly as possible.

           ---------------------------                                  
this Agreement is that of independent contractors. Nothing contained in this

venturers or agents of the other. Neither Party has any express or implied right
or authority under this Agreement to assume or create any obligations or make
any representations or warranties on behalf of or in the name of the other
Party.

     21.2  Assignment.  Neither Party may assign its interest under this

assign this Agreement, in whole or in part, without such consent, to an
Affiliate of such Party.  Any permitted assignee shall assume all obligations of
its assignor under this Agreement.  No assignment shall relieve any Party of
responsibility for the performance of any accrued obligation which such Party
then has hereunder.  Notwithstanding the foregoing, this Agreement shall not
limit either party's ability to merge with, acquire, or be acquired by a Third
Party, or to assign this Agreement in connection with the merger, acquisition,
sale of all or substantially all of the assets to which this Agreement pertains,
change of control or similar transaction, without the prior written consent of
the other party, provided that all obligations and rights of such assigning
party set forth herein shall be binding on any such Third Party or assignee.


     21.3  Payments.  All payments required by this Agreement shall be made in

check or wire transfer to a bank account specified in writing by the receiving
Party. If payment is not made pursuant to an invoice, the paying Party shall
provide the receiving Party with ten (10) business days prior written notice of
a payment. Time for payment shall be of the essence. Unless the paying Party
notifies the receiving Party in writing of a good faith dispute with respect to
amounts not received within such forty-five (45) day period, interest shall
accrue thereon at the rate of prime plus two percent (2%), such interest to
begin accruing on a daily basis from the date of invoice, and shall accrue both
before and after judgment; provided, however, that in the case of a good faith
                           --------  -------             
dispute regarding payment that is resolved to be due and is not paid within
three (3) days after such resolution, interest shall accrue on any amount
overdue at the rate of prime plus two percent (2%), such interest to begin
accruing on a daily basis from the date such payment becomes overdue, and shall
accrue both before and after judgment. For purposes of this Agreement, the rate
of prime shall be that rate of prime quoted by Citibank, N.A., New York, New
York, or any successor entity thereto.

agreement between the Parties concerning the subject matter hereof and
supersedes all written or oral prior agreements or understandings with respect
thereto.

     21.6  Governing Law.  This Agreement shall be construed, interpreted and
           -------------

law provisions.

shall be held invalid, illegal or unenforceable in any respect, such invalidity,
illegality or unenforceability shall not affect any other term or provision
hereof, and this Agreement shall be interpreted and construed as if such term or
provision, to the extent the same shall have been held to be invalid, illegal or
unenforceable, had never been contained herein.  To the extent permitted by
applicable law, the Parties hereto hereby waive any provision of law which
renders any provision hereof prohibited or unenforceable in any respect.

           ----------------------------------------------                
waiver, modification, supplementation or termination of any of the terms or
provisions of this Agreement shall be valid unless in writing and signed by
authorized representatives of both Parties.  Failure by either Party to enforce
any rights under this Agreement shall not be construed as a waiver of such
rights nor shall a waiver by either Party in one or more instances be construed
as constituting a continuing waiver or as a waiver in other instances.

          .  Abbott will help arrange and pay for a carrier to pickup product
             returned due to Abbott's error. Carrier will schedule a time with
             customer for pickup of product. Under all other conditions, the
             customer pays for freight on returned goods shipments.

        or

          .  Customer may arrange and pay for shipment of product to Abbott.

     8. THIRD PARTY RETURNED GOODS COMPANIES may be used to process expired
        product for credit if an authorization form is on file with Abbott for
        each account indicating the third party return company received
        permission from the account to process Abbott returns. (A copy of the
        form is available from Corporate Customer Service 1-800-ABBOTT3 or 
        1-800-222-6883.) The THIRD PARTY RETURNED GOODS COMPANY may return
