                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 31, 1997

1.    ORGANIZATION AND PRINCIPLES OF CONSOLIDATION

      ORGANIZATION
      ------------

           Gensia Sicor Inc, formerly known as Gensia, Inc. ("Gensia Sicor" or
      the "Company"), a Delaware corporation, was incorporated November 17,
      1986. 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 Sintesis Lerma,
      S.A. de C.V. ("Sintesis Lerma"). Gensia Sicor is a specialty
      pharmaceutical company focused on the development, manufacture and
      marketing of products for the worldwide oncology and injectable
      pharmaceutical market. The Company also has a proprietary medical products
      group and a research group focused on pain, inflammation, diabetes and
      cardiovascular. The newly combined company is headquartered in San Diego,
      California.

      PRINCIPLES OF CONSOLIDATION
      ---------------------------

           The consolidated financial statements include the accounts of the
      Company and its seven wholly-owned subsidiaries: Rakepoll Holding,
      Gensia Laboratories, Ltd., Gensia Automedics, Inc., Gensia Europe Limited,
      Gensia GmbH, Aramed, Inc., and Gensia Development Corporation. All
      significant intercompany accounts and transactions have been eliminated.
      The accompanying consolidated balance sheet at March 31, 1997 includes the
      assets, liabilities and stockholder's equity of the combined companies.
      The consolidated statement of operations and statement of cash flows
      include the results for one month for Rakepoll Holding from February 28,
      1997, (the date of acquisition), through March 31, 1997 only.

           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, 1997 and 1996 have
      been made. The results of operations for the three-month period ended
      March 31, 1997 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 1996 Form 10-K filed with the Securities and
      Exchange Commission and the audited financial statements and notes
      thereto of Rakepoll Holding B.V. included in the Company's 1997 Form 8-K/A
      filed with the Securities and Exchange Commission..


2.    THE RAKEPOLL HOLDING ACQUISITION

           On February 28, 1997, after shareholder approval, Gensia Sicor
      acquired all of the outstanding shares of capital stock of Rakepoll
      Holding from Rakepoll Finance in exchange for 29,500,000 shares of the
      Company's Common Stock and $100,000. The acquisition was accounted for
      using the purchase method. Rakepoll Holding is the parent company of three
      specialty pharmaceutical businesses: SICOR-Societa Italiana
      Corticosteroidi S.p.A. of Milan, Italy, and two companies located in
      Mexico: Lemery S.A. de C.V. and Sintesis Lerma, S.A. de C.V. The total
      purchase price was $157.7 million, which was comprised of the fair value
      of Common Stock issued of $146.6 million, acquisition costs of $11.0
      million, and a cash payment of $100,000.

<PAGE>
 
                                GENSIA SICOR INC.

      Based on the purchase price of $157.7 million, allocation of the total
      acquisition cost is as follows:

<TABLE>
           <S>                                       <C>
           Net tangible assets.....................  $  27,542
           Developed technology....................     45,000
           Other intangibles.......................      6,870
           In-process research and development.....     29,200
           Goodwill................................     49,103
                                                     ---------
               Total...............................  $ 157,715
                                                     =========
</TABLE>

           The developed technology and other intangibles are being amortized
      over their estimated lives. The excess of the purchase price over the
      value of identified assets and liabilities, in the amount of $49.1 million
      was recorded as goodwill and is being amortized over its estimated life.
      The value assigned to in-process research and development was immediately
      charged to the statement of operations. This charge is not deductible
      for income tax purposes.

3.    CONTINGENCIES

           During 1995, Rakepoll Holding received claims from certain of its
      customers in connection with shipments of a contaminated product. While no
      lawsuits have been filed against Rakepoll Holding with respect to this
      matter, Rakepoll Holding had a reserve of approximately $2.8 million
      at March 31, 1997, which represents management's best estimate of product
      rework costs, attorneys' costs and other settlement costs. Actual costs to
      be incurred in relation to the ultimate settlement may vary from the
      amount estimated.

4.    NET LOSS PER SHARE

           Net loss per share is computed using the weighted average number of
      common shares outstanding during the period.

           In February 1997, the Financial Accounting Standards Board issued
      Statement of Financial Accounting Standards No. 128, "Earnings Per Share."
      The Company will be required to adopt these new rules effective December
      15, 1997. Management does not anticipate any impact resulting from the
      adoption of this new standard upon current or previously reported primary
      earnings per share.

5.    SUBSEQUENT EVENTS

           In April 1997, the Company entered into an agreement with Sankyo Co.,
      Ltd, of Japan ("Sankyo") to collaborate on a research program to discover
      and develop drugs for the treatment of non-insulin dependent (Type II)
      diabetes. Under the terms of the agreement, the Company will receive an 
      up-Front license fee of $1.4 million and will receive research funding 
      for at least three years, to be paid quarterly. Under the provisions of a
      Letter of Intent signed in March 1997, the Company recorded as revenue, an
      up-front non-refundable commitment fee of $1.4 million from Sankyo. In
      conjunction with this research collaboration, Sankyo, at Gensia Sicor's
      option, may also make up to a $7.3 million equity investment, at a premium
      to market price, in the Company's Common Stock or the common stock of an
      assignee determined by the Company. The Company may receive payments upon
      the achievement of specified milestones if a product is successfully
      developed by Sankyo under the agreement. The Company would also receive
      royalties on any product sales that result from the collaboration.

                                GENSIA SICOR INC.

           In May 1997, the Company entered into an agreement to privately place
      $20 million in convertible notes due in 2004. The notes bear a coupon of
      2.675%. The notes are convertible into Gensia Sicor Convertible Preferred
      Stock or Common Stock at a conversion price of $3.78 per share and include
      Warrants to purchase up to 2,645,503 shares of Gensia Sicor Common Stock
      at $4.35 per share. Fifty percent of these Warrants are Conditional
      Warrants that may not be exercised for three years and will be canceled if
      the Gensia Sicor Common Stock price exceeds certain levels during the
      first three years after the closing. The terms of the agreement contain,
      among other provisions, requirements for maintaining defined levels of net
      worth and various financial ratios, and a provision that the parties will
      enter into a Registration Rights Agreement under which the Company would
      not be required to register the shares of Common Stock into which the
      notes are convertible until August 28, 1998. The financing is expected to
      close in May 1997.

           In May 1997, the Company announced that it had received a letter from
      the U.S. Food and Drug Administration (FDA) indicating that its New Drug
      Application (NDA) for the GenESA System is approvable. The GenESA System
      will be indicated for use in the diagnosis of coronary artery disease in
      conjunction with radionuclide myocardial perfusion imaging for patients
      who cannot exercise adequately. Approval of the product is contingent on
      acceptance by the FDA on final labeling. The Company anticipates being
      able to respond promptly to the request for final labeling and anticipates
      launching the product through its Gensia Automedics subsidiary in the
      third quarter of 1997.

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

      Gensia has been unprofitable on an annual basis since its inception in
1986 and expects to incur additional operating losses at least through 1997. For
the period from its inception to March 31, 1997, the Company has incurred a
cumulative net loss of $303.9 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 the
timely development, regulatory approval, and successful marketing of new
products and acceptance of new products, 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, 1996. 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 $40.3 million, or $.66 per common share
(after dividends on preferred stock of $1.5 million), in the first quarter ended
March 31, 1997 compared to a net loss of $12.8 million, or $.36 per common share
(after undeclared and unpaid dividends on preferred stock of $1.5 million), in
the first quarter of 1996. The first quarter includes the results of Rakepoll
Holding from February 28, 1997, the date of its acquisition and a $29.2 million
write-off of in-process research and development associated with the acquisition
of Rakepoll Holding.

      Product sales in the first quarter of 1997 increased to $19.8 million from
$12.9 million in the first quarter of 1996. The increase in product sales is
attributable to the inclusion of one month of sales reported by the Rakepoll
Holding companies for March. The cost of sales associated with product sales was
$16.5 million for the first quarter of 1997 and $8.5 million for the first
quarter of 1996. The gross margin for the 1997 first quarter decreased compared
to the first quarter of 1996 due to increased competition with respect to
certain of Gensia Laboratories' multisource injectable products and a $1.2
million increase in cost of sales for Rakepoll Holding products resulting from
the write-up of inventory associated with the acquisition of Rakepoll Holding.
Second quarter gross margin will also be negatively effected as the remainder of
the inventory write-up is charged to cost of sales. The Company expects product
sales to grow significantly in 1997, primarily as a result of the acquisition of
Rakepoll Holding on February 28, 1997, and if new products are approved for sale
by the regulatory agencies. There can be no assurance that Gensia Sicor will be
able to achieve growth from new product sales. In May 1997, the Company
announced that it had received a letter from the U.S. Food and Drug
Administration (FDA) indicating that its New Drug Application (NDA) for the
GenESA System is approvable for use in the diagnosis of coronary artery disease
in conjunction with radionuclide myocardial perfusion imaging for patients who
cannot exercise adequately. The Company anticipates launching the product
through its Gensia Automedics subsidiary in the third quarter of 1997.

       In the first quarter of 1997, contract research and license fees were
$2.6 million of which $1.2 million was from research collaboration with Pfizer,
Inc. and $1.4 million was from an up-front non-refundable commitment received
from Sankyo under the provisions of a Letter of Intent signed in March 1997. No
contract research or license fees were recorded in the first quarter of 1996.
The Company expects to record contract research revenue in future quarters
relating to its agreements with Sankyo and Pfizer. The Company is pursuing
additional collaborations which would fund a portion of Gensia's research and
development efforts; however, there can be no assurance that any such agreements
will be reached.

       Interest income for the first quarter of 1997 decreased to $0.2
million from $0.7 million for the first quarter of 1996 due to lower average
cash and investment balances in 1997.


                                       9

                               GENSIA SICOR INC.

      Research and development expenses in the first quarter of 1997 decreased
to $5.9 million from $8.2 million in the 1996 first quarter. The decrease is due
to the reduction of expenses for the Geomatrix nifedipine program as a result of
a restructuring of an agreement with Jago Pharma AG and Boehringer Mannheim
Corporation and due to ongoing expense reduction programs. The future level of
spending in research and development will, in part, depend on the Company's
ability to complete additional collaborations with corporate partners to fund
its research and development programs.

      Selling, general and administrative expenses in the first quarter of 1997
increased to $9.1 million from $7.9 million in the first quarter of 1996, mainly
due to the inclusion of Rakepoll Holding's expenses for March 1997. Selling,
general and administrative expenses are expected to continue to grow as the
Company increases sales and marketing activities to support the GenESA System
product launch, and as Rakepoll Holding is consolidated for a full accounting
period. The amount of any such growth will depend, in part, upon the Company's
success in gaining U.S. regulatory approval for additional multisource
injectable drugs. Expenses are also expected to grow as Gensia Sicor continues
to integrate the Rakepoll Holding business.

      The Company had interest and other income of $0.3 million in the first
quarter of 1997 compared to interest and other expense of $0.3 million in the
first quarter of 1996.

      In the first quarter of 1997, the Company recorded amortization expense of
$0.4 million related to the identified intangibles and goodwill resulting from
the acquisition of Rakepoll Holding.

      In connection with the Rakepoll Holding acquisition, the assets and
liabilities of Rakepoll Holding were adjusted to their estimated fair values,
and the Company incurred a one time $29.2 million write-off related to the value
assigned to the acquired in-process research and development. This charge is not
deductible for income tax purposes.

      The Company is party to a number of agreements with Gensia Clinical
Partners related to the GenESA System technology. Pursuant to these agreements,
the Company is required to make a milestone payment of approximately $5 million
payable in cash or Gensia Sicor Common Stock within a specified time after
approval of the GenESA System by the FDA.

LIQUIDITY AND CAPITAL RESOURCES

      At March 31, 1997, the Company had cash, cash equivalents and short-term
investments of $27.4 million. In March 1997, the Company raised approximately
$17 million through a private placement of Gensia Sicor units for $4.1875 per
unit. Each unit consists of one share of Common Stock and a warrant to purchase
one half of one share of the Company's Common Stock for $4.1875 per share.

      In early May 1997, the Company entered into an agreement to privately
place $20 million in convertible notes due in 2004. The notes bear a coupon of
2.675%. The notes are convertible into Gensia Sicor Convertible Preferred Stock
or Common Stock at a conversion price of $3.78 per share and include Warrants to
purchase up to 2,645,503 shares of Gensia Sicor Common Stock at $4.35 per share.
Fifty percent of these Warrants are Conditional Warrants that may not be
exercised for three years and will be canceled if the Gensia Sicor Common Stock
price exceeds certain levels during the first three years after the closing. The
terms of the agreement contain, among other provisions, requirements for
maintaining defined levels of net worth and various financial ratios, and a
provision that the parties will enter into a Registration Rights Agreement under
which the Company would not be required to register the shares of Common Stock
into which the notes are convertible until August 28, 1998. The financing is
expected to close in May 1997 .

      The Company's current operating plan includes funding its research
activities primarily through collaborations with 

                                       10

                                GENSIA SICOR INC.

other pharmaceutical companies. The Company is currently receiving contract
research revenues through its research collaboration with Pfizer, Inc. In April
1997, the Company entered into an agreement with Sankyo pursuant to which Sankyo
will provide basic research funding to discover and develop drugs for the
treatment of non-insulin dependent (Type II) diabetes for a period of at least
three years, and may provide payments for attainment of certain preclinical and
clinical milestones and royalty payments from commercial sales of any
successfully developed product. Subject to certain consents and availability of
funding, Gensia Sicor plans to transfer certain of its San Diego based
pharmaceutical research and development programs into its newly created 
Metabasis Therapeutics, Inc. subsidiary and spin off such subsidiary to its
shareholders. To the extent the Company is unable to spin off Metabasis
Therapeutics, Inc. and is unable to fund its research activities through its
collaboration with Sankyo and Pfizer, the Company plans to reduce its research
expense to the level necessary to fulfill its obligations under the Pfizer and
Sankyo agreements. There can be no assurance that the Company's product
development efforts with Pfizer and Sankyo will be successful or that Pfizer and
or Sankyo will not terminate their respective collaborations before any such
milestones are achieved or that Gensia Sicor will be able to obtain consents and
financing necessary to spin off Metabasis Therapeutics, Inc. to shareholders.

      The Company anticipates that its current capital resources, commitments
from third parties, including the agreements signed in May 1997 to issue
convertible notes and warrants in exchange for $20 million, and efforts to
reduce overall product costs will enable it to maintain its current and planned
operations through at least 1997. The Company will continue to pursue debt and
lease financing for its capital needs. In addition, as the Company has
indicated, it may seek equity funds to finance its subsidiaries Gensia
Automedics, Inc. and Metabasis Therapeutics, Inc. There can be no assurance that
any such financings will be available on acceptable terms, if at all.

      Gensia Sicor expects to incur additional costs, including the cost of
increased sales and marketing activities to support product launches and
increased emphasis on overall commercial activities. Management also plans to
invest in plant and equipment to increase and improve the existing manufacturing
capacity in the acquired Rakepoll Holding businesses. Increased spending will
also be required to integrate the Gensia and Rakepoll Holding businesses. Any
difficulties experienced in integrating the operations of the companies
successfully could have a material adverse effect on the business and results of
operations of the combined company. The amount of such additional costs, as well
as the increased spending necessary for working capital and capital
requirements, will depend on numerous factors including the successful
integration of the Gensia Sicor companies, the timing of any final regulatory
approval of the GenESA System in the U.S., the Company's ability to market this
product in the U.S. and Europe if appropriate regulatory approvals are obtained,
and Gensia's success at maintaining or improving Gensia Laboratories' current
sales and profitability. In May 1997, the Company announced that it had received
a letter from the FDA indicating that its NDA for the GenESA System is
approvable for use in the diagnosis of coronary artery disease in conjunction
with radionuclide myocardial perfusion imaging for patients who cannot exercise
adequately. The Company anticipates launching the product through its Gensia
Automedics, Inc. subsidiary in the third quarter of 1997. Also, Gensia
Laboratories is undertaking a significant capital expenditure program in 1997
related to the development of an oncology manufacturing facility. The Company
has commitments to finance this expansion largely through lease or debt
financing secured against certain assets of Gensia Laboratories. There can be no
assurance such financing will remain available on acceptable terms, if at all.

      Significant changes in operating assets and liabilities during the first
quarter of 1997, excluding the net assets from the Rakepoll Holding acquisition,
included a $5.8 million increase in accounts payable, a $2.4 million decrease in
accounts receivable and a $1.7 million increase in inventories. Other
significant cash flows in the first quarter of 1997 included $8.9 million for
the transaction costs associated with the acquisition of Rakepoll Holding as of
February 28, 1997, net of cash acquired of $2.2 million, $19.8 million received
from the issuance of common stock and warrants, primarily as a result of private
placement of 4.2 million shares of Gensia Common Stock in March 1997 and $2.8
million expended on property and equipment.

      The Company made quarterly cash dividend payments of approximately $1.5
million per quarter on its outstanding preferred stock from June 1, 1993 through
March 1, 1995. Subsequent to March 1995, as a measure to reduce cash outflows,
the Company's Board of Directors suspended quarterly cash dividend payments on
its outstanding preferred stock. The Company resumed quarterly payment of the
Preferred Stock dividend in September 1996. At March 31, 1997, the Company had
approximately $7.5 million in undeclared cumulative preferred dividends. If the
Company chooses to not declare dividends for six cumulative quarters, the
holders of this preferred stock, voting separately as a class, will be entitled
to elect two additional directors until the dividend in arrears has been paid.

or encumbrances arising through the Company; and when the Warrant Shares are
issued in accordance with the terms of the Warrant, they will be validly issued
and outstanding, fully paid and nonassessable and free of any liens or
encumbrances arising through the Company. Subject to compliance with the
provisions of applicable securities laws of state or foreign jurisdictions, no
other approval of any public body (state or federal) is or will, on the Closing
Date be necessary in connection with the offer, issue and sale of the Initial
Shares and the Warrant as contemplated herein.

Company's Certificate of Incorporation, the Company's by-laws, or any material

the Company is a party or by which it is bound.

corporate authority to own, lease and operate its properties and conduct its

taken as a whole; to the knowledge of the Company, each of the Company and its
subsidiaries is in possession of and operating in compliance with all
authorizations, licenses, certificates, consents, orders and permits from state,

business, all of which are valid and in full force and effect to the extent that
the failure of such would have a material adverse effect on the Company's
business or results from operations; and each of the Company and its
subsidiaries is not in violation of its respective charter or bylaws.

     4.    Representations and Warranties of the Purchaser; Access to
           ----------------------------------------------------------
Information; Independent Investigation.  The Purchaser hereby represents and
- --------------------------------------

investment for its own account only and not with a view to, or for resale in
connection with, any "distribution" thereof within the meaning of the Securities
Act.  The Purchaser understands that the Securities have not been registered
under the Securities Act or registered or qualified under any state securities
law in reliance on specific exemptions therefrom, which exemptions may depend
upon, among other things, the bona fide nature of Purchaser's investment intent
as expressed herein.

     4.2   Investment Experience.  The Purchaser is an "accredited investor"
           ---------------------                                            
within the meaning of Rule 501 of the Commission, and was not organized for the
specific purpose of acquiring the Units.  The Purchaser is aware of the
Company's business affairs and financial condition and has acquired sufficient
information about the Company to reach an informed and knowledgeable decision to
acquire the Units.  The Purchaser has such business and financial experience as
is required to give it the capacity to protect its own interests in connection
with the purchase of the Securities.

     4.3   Authorization.  This Purchase Agreement has been duly and validly
           -------------                                                    
authorized, executed and delivered on behalf of the Purchaser and is a valid and
binding agreement of the Purchaser enforceable in accordance with its terms,
subject as to enforceability to general principles of equity and to bankruptcy,
insolvency, moratorium and other similar laws affecting the enforcement of
creditors' rights generally.

     4.4   Compliance with Securities Laws and Regulations.  All subsequent
           -----------------------------------------------                 
offers and sales of the Securities by the Purchaser shall be made pursuant to
registration under the Securities Act and qualification under the applicable
state securities laws or pursuant to exemptions from registration and
qualification.

    4.5    Reliance by Company.  The Purchaser understands that the Units are
           -------------------                                               
being offered and sold to it in reliance on specific exemptions from the
registration and qualification requirements of United States federal and state
securities laws and that the Company is relying upon the truth and accuracy of,
and the Purchaser's compliance with the representations, warranties, agreements,
acknowledgments and understandings of the Purchaser set forth herein in order to
determine the availability of such exemptions and the eligibility of the
Purchaser to acquire the Securities.

                                       6
<PAGE>
 
     4.6   No Government Approval.  The Purchaser understands that no United
           ----------------------                                           
States federal or state agency or any other government or governmental agency
has passed on or made any recommendation or endorsement of the Units.

     4.7   No Legal, Tax or Investment Advice.  The Purchaser understands that
           ----------------------------------                                 
nothing in the Purchase Agreement or any other materials presented to the
Purchaser in connection with the purchase and sale of the Units constitutes
legal, tax or investment advice.  The Purchaser has consulted such legal, tax
and investment advisors as it, in its sole discretion, has deemed necessary or
appropriate in connection with its purchase of the Units.

     4.8   Access to Information.  The Purchaser acknowledges that it has had
           ---------------------
the opportunity to ask questions, to receive answers concerning the terms and
conditions of this offering from the Company and to obtain any additional
information from the Company that the Company possesses or can acquire without
unreasonable effort or expense regarding this offering.

     4.9   Individual Investor.  If Purchaser is a natural person, Purchaser
           -------------------

     5.4   Indemnification and Contribution.
           -------------------------------- 

           5.4.1  Indemnification by the Company.  The Company agrees to
                  ------------------------------
indemnify and hold harmless each Holder from and against any losses, claims,
damages or liabilities (or actions or proceedings in respect thereof) to which
such Holder may become subject (under the Securities Act or otherwise) insofar
as such losses, claims, damages or liabilities (or actions or proceedings in
respect thereof) arise out of, or are based upon, any claim by a third party
asserting any untrue statement of a material fact contained in the Registration
Statement, on the effective date thereof, or arise out of any failure by the
Company to fulfill any undertaking included in the Registration Statement, and
the Company will, as incurred, reimburse such Holder for any legal or other
expenses reasonably incurred in investigating, defending or preparing to defend
any such action, proceeding or claim; provided, however, that the Company shall
                                      --------  -------
not be liable in any such case to the extent that such loss, claim, damages or
liability arises out of, or is based upon (i) an untrue statement or alleged
untrue statement made in such Registration Statement in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
such Holder specifically for use in preparation of the Registration Statement or
(ii)) any untrue statement in any prospectus that is corrected in any subsequent
prospectus that was delivered to the Holder prior to the pertinent sale or sales
by the Holder.

           5.4.2  Indemnification by Holder.  Each Holder, severally and not
                  -------------------------
jointly, agrees to indemnify and hold harmless the Company from and against any
losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) to which the Company may become subject (under the Securities Act or
otherwise) insofar as such losses, claims, damages or liabilities (or actions or
proceedings in respect thereof) arise out of, or are based upon any claim by a
third party asserting (i) an untrue statement made in such Registration
Statement in reliance upon and in conformity with written information furnished
to the Company by or on behalf of such Holder specifically for use in
preparation of the Registration Statement, provided, however, that no Holder
                                           --------  -------                
shall be liable in any such case for any untrue statement included in any
Prospectus which statement has been corrected, in writing, by such Holder and
delivered to the Company at least three business days before the sale from which
such loss occurred or (ii) any untrue statement in any prospectus that is
corrected in any subsequent prospectus that was delivered to the Holder prior to
the pertinent sale or sales by the Holder, and each Holder, severally and not
jointly, will, as incurred, reimburse the Company for any legal or other
expenses reasonably incurred in investigating, defending or preparing to defend
any such action, proceeding or claim.

           5.4.3  Indemnification Procedures.  Promptly after receipt by any
                  --------------------------                                
indemnified person of a notice of a claim or the beginning of any action in
respect of which indemnity is to be sought against an indemnifying person
pursuant to this Section 5.4, such indemnified person shall notify the
indemnifying person in writing of such claim or of the commencement of such
action, and, subject to the provisions hereinafter stated, in case any such
action shall be brought against an indemnified person and the indemnifying
person shall have been notified thereof, the indemnifying person shall be
entitled to participate therein, and, to the extent that it shall wish, to
assume the defense thereof, with counsel reasonably satisfactory to the
indemnified person.  After notice from the indemnifying person to such
indemnified person of the indemnifying person's election to assume the defense
thereof, the indemnifying person shall not be liable to such indemnified person
for any legal expenses subsequently incurred by such indemnified person in
connection with the defense thereof; provided, however, that if there exists or
                                     --------  -------                         
shall exist a conflict of interest that would make it inappropriate in the
reasonable opinion of counsel for the indemnified person for the same counsel to
represent both the indemnified person and such indemnifying person or any
affiliate or associate thereof, the indemnified person shall be entitled to
retain its own counsel at the expense of such indemnifying person; provided,
                                                                   -------- 
however, that in the case of the immediately preceding proviso the indemnifying
- -------                                                                        
person shall not be responsible for the legal expenses of more than one counsel
for all indemnified persons.

           5.4.4  Contribution in Lieu of Indemnity.  If the indemnification
                  ---------------------------------                         
provided for in this Section 5.4 is unavailable to or insufficient to hold
harmless an indemnified party under Section 5.4.1 or 5.4.2 above in respect of
any losses, claims, damages or liabilities (or actions or proceedings in respect
thereof) referred to therein, then each indemnifying party shall contribute to
the amount paid or payable by such indemnified party as result of such losses,
claims, damages or liabilities (or actions in respect thereof), as well as any
other relevant equitable considerations.  The relative fault shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company on the one hand or
a Holder on the other and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Holders agree that it would not be just and equitable if
contribution pursuant to this Section 5.4.4 were determined by pro rata
allocation (even if the Holders were treated as one entity for such purpose) or
by any other method of allocation which does not take account of the equitable
considerations referred to above in this Section 5.4.4. The amount paid or
payable by an indemnified party as a result of the losses, claims, damages or
liabilities (or actions in respect thereof) referred to above in this Section
5.4.4

shall be deemed to include any legal or other expenses reasonably incurred by
such indemnified party in connection with investigating or defending any such
action or claim. Notwithstanding the provisions of this Section 5.4.4, no Holder
shall be required to contribute any amount in excess of the net amount received
by the Holder from the sale of the Registrable Securities to which such loss
relates. No person guilty of fraudulent misrepresentation (within the meaning of
Section 11 (f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation. The Holders'
obligations in this Section 5.4.4 to contribute are several in proportion to
their respective sales of Registrable Securities to which such loss relates and
not joint.

           5.4.5  Controlling Persons Indemnified.  The obligations of the
                  -------------------------------
Company and the Holders under this Section 5.4 shall be in addition to any
liability which the Company and the respective Holders may otherwise have and
shall extend, upon the same terms and conditions, to each person, if any, who
controls the Company or any Holder within the meaning of the Securities Act.

     5.5   Transfer of Registration Rights.  The right to sell Registrable
           -------------------------------                                
Securities pursuant to the registration statement described herein will
automatically be assigned to each transferee of at least 50,000 Initial Shares
or Warrant Shares.  In the event that it is necessary, in order to permit a
Holder to sell Registrable Securities pursuant to the Registration Statement, to
amend the Registration Statement to name such Holder, such Holder shall, upon
written notice to the Company, be entitled to have the Company make such
amendment as soon as reasonably practicable.  Notwithstanding the above
provisions relating to Registration Expenses, in the event that such an
amendment is requested, the Holder shall, at the request of the Company, be
obligated to reimburse the Company for reasonable Registration Expenses incurred
by it in connection with such amendment.

     5.6   Reports Under the Exchange Act.  With a view to make available to the
           ------------------------------                                       
Purchasers or Holders the benefits of Rule 144 promulgated under the Securities
Act and any other rule or regulation of the SEC that may at any time permit a
Purchaser or Holder to sell Securities to the public without registration or
pursuant to a registration on Form S-3, the Company will covenant and agree to:
(i) make and keep public information available, as those terms are understood
and defined in Rule 144, at all times after the Closing; (ii) file with the SEC
in a timely manner all reports and other documents required of the Company under
the Securities Act and the Exchange Act; and (iii) furnish to any Purchaser or
Holder, so long as the Purchaser or Holder owns any Securities forthwith upon
request, (A) a written statement by the Company that it has complied with the
reporting requirements of Rule 144, the Securities Act and the Exchange

Act, (B) a copy of the most recent annual or quarterly report of the Company,
and (C) such other information as may be reasonably requested in order to avail
any Purchaser or Holder of any rule or regulation of the SEC that permits
the selling of any such Securities without registration or pursuant to such
Form S-3.

                   WARRANT TO PURCHASE SHARES OF COMMON STOCK
                              OF GENSIA SICOR INC.

                         --------
to purchase from Gensia Sicor Inc., a Delaware corporation (the "Company"),
                 (        ) fully paid and nonassessable shares of the Company's
- ----------------  --------
Common Stock (the "Warrant Shares") at a price of $4.1875 per share (the "Stock
Purchase Price") at any time or from time to time on or after the Commencement
Date (as defined below) up to and including 5:00 p.m. (Pacific time) on the
Expiration Date (as defined below), upon surrender to the Company at its

properly endorsed with the Form of Subscription attached hereto duly filled in

Date" means the earlier of (i) December 31, 2002 (five years from the

                                       1
<PAGE>
 
Section 3.4. This Warrant is issued pursuant to the Unit Purchase Agreement
between the Company and Holder dated as of the date hereof (the "Purchase
Agreement").

     This Warrant is subject to the following terms and conditions:

     1.   Exercise of Warrant
          -------------------

     1.1  Issuance of Certificates.  This Warrant is exercisable at the option
          ------------------------                                            
of Holder at any time or from time to time on or after the Commencement Date and
prior to or on the Expiration Date for all or a portion of the shares of Warrant
Shares which may be purchased hereunder.  The Company agrees that the Warrant
Shares purchased under this Warrant shall be and are deemed to be issued to
Holder as the record owner of such shares as of the close of business on the
date on which this Warrant shall have been surrendered and payment made for such
shares.  Subject to the provisions of Section 2, certificates for the Warrant
Shares so purchased, together with any other securities or property to which
Holder is entitled upon such exercise, shall be delivered to Holder by the
Company's transfer agent at the Company's expense within a reasonable time after
this Warrant has been exercised.  Each stock certificate so delivered shall be
in such denominations of Warrant Shares as may be requested by Holder and shall
be registered in the name of Holder or such other name as shall be designated by
Holder, subject to the limitations contained in Section 2.  If, upon exercise of
this Warrant, fewer than all of the Warrant Shares evidenced by this Warrant are
purchased prior to the date of expiration of this Warrant, one or more new
warrants substantially in the form of, and on the terms in, this Warrant will be
issued for the remaining number of Warrant Shares not purchased upon exercise of
this Warrant.

     1.2  Payment.  Payment of the Stock Purchase Price shall be made at the
          -------                                                           
option of Holder by surrender to the Company of this Warrant properly endorsed
with the Form of Subscription attached hereto duly filled in and signed and (i)
payment by cash, cashier's check or wire transfer of immediately available funds
or (ii) by surrender of this Warrant to the Company, with a duly executed
exercise notice marked to reflect "Net Issue Exercise," and, in either case,
specifying the number of Warrant Shares to be purchased, during normal business
hours on any day that is not a Saturday or Sunday or a day on which banks are
required or permitted to be closed in the State of California.  Upon a Net Issue
Exercise, Holder shall be entitled to receive Warrant Shares equal to the value
of this Warrant (or the portion thereof being exercised by Net Issue Exercise)
by surrender of this Warrant to the Company together with notice of such
election, in which event the Company shall issue to Holder a number of Warrant
Shares computed as of the date of surrender of this Warrant to the Company using
the following formula:

                                       2
<PAGE>
 
               X =  Y x (A-B)
                    ---------
                       A

     Where     X =  the number of Warrant Shares to be issued to Holder pursuant
                    to this Section 1.2;

               Y =  the number of Warrant Shares otherwise purchasable under
                    this Warrant, or any lesser number of Warrant Shares as to
                    which this Warrant is being exercised (at the date of such
                    calculation);

               A =  the fair market value of one share of the Company's Common
                    Stock (at the date of such calculation);

               B =  the Stock Purchase Price (as adjusted to the date of such
                    calculation).

     2.   Shares to be Fully Paid; Reservation of Shares.  The Company covenants
          ----------------------------------------------                        
and agrees that all Warrant Shares which may be issued upon the exercise of the
rights represented by this Warrant will, upon issuance, be duly authorized,
validly issued, fully paid and nonassessable and free from all preemptive rights
of any stockholder and free of all taxes, liens and charges with respect to the
issue thereof.  The Company further covenants and agrees that during the period
within which the rights represented by this Warrant may be exercised, the
Company will use its best efforts to at all times have authorized and reserved,
for the purpose of issue or transfer upon exercise of this Warrant, a sufficient
number of shares of authorized but unissued Common Stock.  When and as required
to provide for the exercise of the rights represented by this Warrant, the
Company will take all such action as may be necessary to assure that such shares
of Common Stock may be issued as provided herein without violation of any
applicable law or regulation, or of any requirements of any domestic securities
exchange or automated quotation system upon which the Common Stock may be
listed.  If for any reason the Company does not have available sufficient
authorized but unissued shares to permit full exercise of this Warrant at any
time, then it may, in its discretion, pay to the Holder an amount in cash equal
to the fair market value of the Warrant Shares the Holder has elected to
purchase by exercise of this Warrant, instead of issuing Warrant Shares to the
Holder.  For purposes of this Warrant, the fair market value of one Warrant
Share shall mean, to the extent it applies to the Company's Common Stock, the
average of the daily high and low trading prices of the Company's Common Stock
on the Nasdaq National Market (or other exchange or market that is the primary
trading market for the Company's Common Stock at that time, as determined by the
Company's Board of Directors in good faith) on the ten trading days prior to the
date the Warrant is exercised and, to the extent it applies to other securities
or property, as determined by the Company's Board of Directors in good faith.

     3.   Adjustment of Stock Purchase Price; Number of Shares.  The Stock
          ----------------------------------------------------            
Purchase Price and the number of shares of Warrant Shares purchasable upon the
exercise of this Warrant shall be subject to adjustment from time to time upon
the occurrence of certain events described in this Section 3.

          3.1   Adjustment of Purchase Price.  In the event that the Company at
                ----------------------------                                   
any time or from time to time after the issuance of this Warrant shall declare
or pay, without consideration, any dividend on the Common Stock payable in
Common Stock or in any right to acquire Common Stock for no consideration, or
shall effect a subdivision of the outstanding shares of Common Stock into a
greater number of shares of Common Stock (by stock split, reclassification or
otherwise than by payment of a dividend in Common Stock or in any right to
acquire Common Stock), or in the event the outstanding shares of Common Stock
shall be combined or consolidated, by reclassification or otherwise, into a
lesser number of shares of Common Stock, then the Stock Purchase Price in effect
immediately prior to such event shall, concurrently with the effectiveness of
such event, be proportionately decreased or increased, as appropriate.  In the
event that the Company shall declare or pay, without consideration, any dividend
on the Common Stock payable in any right to acquire Common Stock for no
consideration, then the Company shall be deemed to have made a dividend payable
in Common Stock in an amount of shares equal to the maximum number of shares
issuable upon exercise of such rights to acquire Common Stock.  Upon each
adjustment of the Stock Purchase Price pursuant to this Section 3.1, the holder
of this Warrant shall thereafter be entitled to purchase, at the Stock Purchase
Price resulting from such adjustment, the number of shares of Common Stock
obtained by multiplying the Stock Purchase Price in effect immediately prior to
such adjustment by the number of shares of Common Stock purchasable pursuant
hereto immediately prior to such adjustment, and dividing the product thereof by
the Stock Purchase Price resulting from such adjustment.

          3.2   Adjustments for Reclassification and Reorganization.  If the
                ---------------------------------------------------
Common Stock shall be changed into the same or a different number of shares of
any other class or classes of stock, whether by capital reorganization,
reclassification or otherwise (other than a subdivision or combination of shares
provided for in Section 3.1), the Stock Purchase Price then in effect shall,
concurrently with the effectiveness of such reorganization or reclassification,
be proportionately adjusted so that this Warrant shall represent the right to
purchase, in lieu of the number of shares of Common Stock which this Warrant
would otherwise represent the right to purchase, a number of shares of such
other class or classes of stock equivalent to the number of shares of Common
Stock which this Warrant would have otherwise entitled the holder to purchase
immediately before that change.

          3.3   Notice of Adjustment.  Upon any adjustment of the Stock Purchase
                --------------------                                            
Price or any increase or decrease in the number of shares of Common Stock
purchasable upon the exercise of this

                                       4
<PAGE>
 
Warrant, the Company shall within five business days give written notice
thereof, by first class mail, postage prepaid, (or by international delivery
service, for international addresses) addressed to the registered holder of this
Warrant at the address of such holder as shown on the books of the Company. The
notice shall be signed by the Company's chief financial officer and shall state
the Stock Purchase Price resulting from such adjustment and the increase or
decrease, if any, in the number of shares purchasable at such price upon the
exercise of this Warrant, setting forth in reasonable detail the method of
calculation and the facts upon which such calculation is based.

          3.4   Other Notices.  If at any time:
                -------------                  

                (a)  the Company shall propose to declare any cash dividend upon
its Common Stock;

                (b)  the Company shall propose to declare or make any dividend
or other distribution to the holders of its Common Stock, whether in cash,
property or other securities;

                (c)  the Company shall propose to effect any reorganization or
reclassification of the capital stock of the Company or any consolidation or
merger of the Company with or into another corporation or any sale, lease or
conveyance of all or substantially all of the property of the Company; or

                (d)  the Company shall propose to effect a voluntary or
involuntary dissolution, liquidation or winding-up of the Company;

then, in any one or more of said cases, the Company shall give, by certified or
registered mail, postage prepaid, or international delivery service for
international deliveries, addressed to the holder of this Warrant at the address
of such holder as shown on the books of the Company, (i) at least fifteen (15)
business days' prior written notice of the date on which the books of the
Company shall close or a record shall be taken for such dividend or distribution
or for determining rights to vote in respect of any such reorganization,
reclassification, consolidation, merger, sale, lease, conveyance, dissolution,
liquidation or winding-up, and (ii) in the case of any such reorganization,
reclassification, consolidation, merger, sale, lease, conveyance, dissolution,
liquidation or winding-up, at least fifteen (15) business days' written notice
of the date when the same shall take place.  Any notice given in accordance with
clause (i) above shall also specify, in the case of any such dividend or
distribution, the record date for such dividend or distribution, if after the
Commencement Date.  Any notice given in accordance with clause (ii) above shall
also specify the date on which the holders of Common Stock shall be entitled to
exchange their Common Stock for securities or other property, if any,
deliverable upon such reorganization, reclassification, consolidation/merger,
sale, lease, conveyance, dissolution, liquidation or winding-up, as the case may
be. In the event that the Holder of the Warrant

                                       5
<PAGE>
 
does not exercise this Warrant prior to the occurrence of an event described in
clause (a) or (b) above, the Holder shall not be entitled to receive the
benefits accruing to existing holders of the Common Stock in such event. Upon
the occurrence of an event described in clause (c), the Holder shall be entitled
thereafter, upon payment of the Stock Purchase Price in effect immediately prior
to such action, to receive upon exercise of this Warrant the class and number of
shares which the Holder would have been entitled to receive after the occurrence
of such event had this Warrant been exercised immediately prior to such event.
In connection with the transactions described in clause (c), the Company will
require each person (other than the Company) that may be required to deliver any
cash, stock, securities or other property upon the exercise of this Warrant as
provided herein to assume, by written instrument delivered to, and reasonably
satisfactory to, the holder of this Warrant (x) the obligations of the Company
under this Warrant and (y) the obligation to deliver to such holder such cash,
stock, securities or other property as such holder may be entitled to receive in
accordance with the provisions of this Section 3. Upon the occurrence of an
event the proposal of which is described in clause (d), this Warrant shall
terminate. Notwithstanding any other provision hereof, no Holder shall have the
right to obtain an injunction or restraining order or otherwise interfere with
or prevent the occurrence of any of the actions described in (a) - (d) above.

     4.   Issue Tax.  The issuance of certificates for the Warrant Shares upon
          ---------                                                           
the exercise of the Warrant shall be made without charge to the holder of the
Warrant for any issue tax in respect thereof; provided, however, that the
Company shall not be required to pay any tax which may be payable in respect of
any transfer involved in the issuance and delivery of any certificate in a name
other than that of the then holder of the Warrant being exercised.

     5.   No Voting or Dividend Rights; Limitation of Liability.  Nothing
          -----------------------------------------------------          
contained in this Warrant shall be construed as conferring upon the holder
hereof the right to vote or to consent or to receive notice as a stockholder in
respect of meetings of stockholders for the election of directors of the Company
or any other matters or any rights whatsoever as a stockholder of the Company.
Except for the adjustment to the Stock Purchase Price pursuant to Section 3.2 in
the event of a dividend on the Common Stock payable in shares of Common Stock,
no dividends or interest shall be payable or accrued in respect of this Warrant
or the interest represented hereby or the shares purchasable hereunder until,
and only to the extent that, this Warrant shall have been exercised.  No
provisions hereof, in the absence of affirmative action by the holder to
purchase shares of Warrant Shares, and no mere enumeration herein of the rights
or privileges of the holder hereof, shall give rise to any liability of such
holder for the Stock Purchase Price or as a stockholder of the Company whether
such liability is asserted by the Company or by its creditors.

follows:

          3.1   Purchaser realizes that Purchaser's purchase of the Securities

loss of Purchaser's investment.

          3.2   Purchaser has carefully considered and has, to the extent
Purchaser believes such discussions necessary, discussed with Purchaser's
professional, legal, tax and financial advisors the suitability of an investment

the Securities are a suitable investment for Purchaser.

          3.3   Purchaser has such knowledge and experience in business and
financial matters as will enable Purchaser to evaluate the merits and risks of
an investment in the Securities and to make an informed investment decision.

will provide such information to the Company as soon as practicable thereafter.

          3.7   Purchaser understands that the Company is relying on the truth
and accuracy of the declarations, representations, warranties and agreements
made by Purchaser to the Company herein in transferring the Securities to
Purchaser.

          3.8   Purchaser confirms that Purchaser has received no general
solicitation or general advertisement and has attended no seminar or meeting

in each of the two most recent years or joint income with that person's spouse

discretion whether such Recommended Compound is appropriate to conduct more
extensive preclinical development under this Agreement to evaluate its potential
as a clinical candidate.  If, within such [CONFIDENTIAL TREATMENT REQUESTED]
period, Sankyo gives written notice to Gensia Sicor that the appropriate
research and development committee of Sankyo has selected such Recommended
Compound to conduct further preclinical development under this Agreement,
thereafter such Recommended Compound shall be a Candidate Compound.

     4.4  Exercise of Option to License Licensed Compounds.  For a period of
          ------------------------------------------------                  
[CONFIDENTIAL TREATMENT REQUESTED] after selection of a Candidate Compound,
Sankyo shall have the right to conduct more extensive preclinical development
and evaluation of such Candidate Compound as a clinical candidate, and to
exercise in its sole discretion its option to license such Candidate Compound in
accordance with the provisions of this Agreement.  If, within such [CONFIDENTIAL
TREATMENT REQUESTED] period, Sankyo gives written notice to Gensia Sicor of the
exercise of its option to license such Candidate Compound in accordance with the
provisions of this Agreement, thereafter such Candidate Compound shall be a
Licensed Compound, and the parties promptly shall prepare and execute a License
Agreement for such Licensed Compound.

     4.5  Clinical Development.
          -------------------- 

     4.5.1   Responsibility to Develop.  Sankyo is to be responsible for all
             -------------------------                                      
clinical development and regulatory approvals and shall own all such approvals,
provided that in the event that Gensia Sicor terminates this Agreement pursuant
- --------                                                                       
to Section 14.2 hereof, Sankyo shall transfer all such registrations to Gensia
Sicor.  Gensia Sicor may attend meetings held by Sankyo respecting development
of Licensed Compounds, and Sankyo will provide notice to Gensia Sicor of such
meetings in a reasonable and timely manner and solicit Gensia Sicor input, but
no such development meetings need be delayed, postponed or altered to
accommodate participation by Gensia Sicor.  Notwithstanding the foregoing,
Sankyo shall neither commence human clinical trials of any Compound, nor file
any regulatory application therefor, unless and until such Compound is a
Licensed Compound, and the parties have prepared and executed a License
Agreement for such Licensed Compound.

     4.5.2  Clinical Development and Marketing.  The preclinical and clinical
            ----------------------------------                               
development of Licensed Compounds shall be the responsibility of Sankyo.  For
each Licensed Compound, Sankyo shall use reasonable diligence and scientific
judgment to evaluate and develop such Licensed Compounds in a timely manner in
accordance with industry standards and Sankyo's internal practices and advise
Gensia Sicor as to the status of such Licensed Compounds.  Sankyo agrees to
conduct such preclinical and human clinical trials as are necessary to obtain
all regulatory approvals to manufacture and market Products in each Primary
Country in the Territory, and diligently, consistent with industry standards
generally, develop, obtain necessary approval to market and commence marketing
each such Product in Primary Countries.  For the purposes of this Agreement,
"Primary Countries" shall mean Australia, the Benelux countries, Canada, France,
Germany, Italy, Japan, the Scandinavian countries, Spain, Switzerland, the
United Kingdom and the United States.  Sankyo shall use reasonable diligence,
consistent with industry standards generally, to develop and market Products in
other countries ("the non-Primary Countries") in the Territory unless in its
reasonable business judgment such development and marketing is not practical or
strategically inadvisable.  Notwithstanding anything to the contrary in this
Agreement, if Sankyo does not diligently develop and market a Product
incorporating a Licensed Compound in a Primary Country, or in a non-Primary
Country where Sankyo has not made a reasonable business judgment that to develop
and market such Product is not practical or strategically inadvisable, then
following one hundred eighty (180) days' written notice by Gensia Sicor to
Sankyo if such breach has not been remedied, (a) the license and other rights
granted to Sankyo with respect to such Licensed Compound and such country shall
become co-exclusive with Gensia Sicor, and (b) Sankyo automatically shall grant
to Gensia Sicor a nonexclusive license, with the right to sublicense, to use
Sankyo's data and regulatory filings as necessary to develop, make, use, import
and sell Products incorporating such Licensed Compound in such country.

     4.5.3   Development Information.  Sankyo shall keep Gensia Sicor informed
             -----------------------                                          
as to the progress of Sankyo in the development and testing of all Licensed
Compounds and Products and the preparing, filing and obtaining of the approvals
necessary for marketing.  In addition, Sankyo shall provide Gensia Sicor with a
minimum of three (3) months' advance notice of the contemplated filing of an IND
or an NDA.  Sankyo shall also provide Gensia Sicor with a report on all
regulatory submissions, communications or meetings on or prior to the date of
such submissions and a copy of any INDs, NDAs or other regulatory communication
within five (5) days of filing thereof, which material shall be subject to non-
disclosure obligations as provided for in Article 11 hereof except as otherwise
set forth herein.

as Licensed Compounds, and any Licensed Compounds that have been dropped by
Sankyo or have not been diligently developed or commercialized by Sankyo, its
Affiliates or sublicensees, shall revert to Gensia Sicor if such Compounds were
Gensia Sicor compounds or Gensia Sicor's Third Party Compounds, and shall revert
to Sankyo if such Compounds were Sankyo compounds or Sankyo's Third Party
Compounds.  Thereafter, the parties shall be free to develop such Compounds
without restriction other than the confidentiality obligations which may be
applicable under Article 11 or as otherwise set forth in this Agreement.

     4.6.2 Notwithstanding the above, if within a period of [CONFIDENTIAL
TREATMENT REQUESTED] after reversion of any such Compound to Sankyo under
Section 4.6.1 above, Sankyo, its Affiliates or (sub)licensees develop such
Compound for use in the Field, or within a period of [CONFIDENTIAL TREATMENT
REQUESTED] after termination of this Agreement, Sankyo, its Affiliates or
(sub)licensees develops any other compound for use in the Field, then such
Compound or compound will be subject to the payment obligations, co-promotion
rights and other rights in favor of Gensia Sicor under this Agreement.

     4.6.3   Notwithstanding the above, for a period of [CONFIDENTIAL TREATMENT
REQUESTED] after reversion of any such Compound to Gensia Sicor under Section
4.6.1 above, Gensia Sicor shall not license to, or otherwise collaborate with
any Third Party to develop and commercialize, such Compound for use in the
Field; provided, however, that (a) after the expiration of the Research Program

commercialize such Compound for use in the Field, and (b) if, after the
expiration or termination of this Agreement, Sankyo is not diligently developing
or commercializing at least one Licensed Compound or Product, then Gensia Sicor
shall have the right without restriction to license to, or otherwise collaborate
with any Third Party to develop and commercialize, such Compound for use in the
Field.

     4.6.4   If Gensia Sicor, its Affiliates or (sub)licensees develops and
commercializes any Compound which has reverted to Gensia Sicor under Section
4.6.1 above, Gensia Sicor shall pay to Sankyo the following royalties based on
Net Sales by Gensia Sicor, its Affiliates or (sub)licensees of products
incorporating such Compound for use in the Field:

     (a) [CONFIDENTIAL TREATMENT REQUESTED], if Sankyo has exercised its option
     to license at least one Licensed Compound which Sankyo is diligently
     developing and commercializing in accordance with the provisions of this
     Agreement; or

     (b) [CONFIDENTIAL TREATMENT REQUESTED], if Sankyo has not exercised its
     option to license at least one Licensed Compound, or is not diligently
     developing and commercializing

                                      -12-

issuer of such shares.  Sankyo's obligation to purchase such shares shall be
subject to its completion, during such ninety (90) day period, of satisfactory
due diligence regarding the business and financial condition of the issuer of
such shares.

     7.4  Development Milestone Payments.  Sankyo shall make the following
          ------------------------------                                  
development milestone payments to Gensia Sicor (a) for the first Compound which
achieves the milestone events set forth in the table below, in the amounts and
in accordance with the table below, and (b) for each additional Compound which
achieves the milestone events set forth in the table below, in one-half (1/2)
the amounts and in accordance with the table below; in each case other

                                      -18-
<PAGE>
 
than for Compounds which have properties, results and effects that are
substantially similar to a Compound (a "Back-up Compound") for which Sankyo has
previously made milestone payments.  Sankyo shall not make milestone payments
for any Back-up Compound unless it replaces a Compound which has been selected
as either a Candidate Compound or a Licensed Compound which has not gone to
market, and in this instance, the only milestone payments due are those which
have not been made for the Compound it replaces.  After any such previously
unpaid milestone payments have been paid, such Back-up Compound shall no longer
be a Back-up Compound.  Notwithstanding the above, if such Back-up Compound is
subsequently developed in addition to the Compound it was meant to replace, all
appropriate milestone payments (for those milestones which such Back-up Compound
already has achieved) shall be promptly paid upon initiation of Phase III
clinical studies (or its regulatory equivalents in the United States or in a
Primary Country) for that Back-up Compound.

          [CONFIDENTIAL TREATMENT REQUESTED]

     7.5  Combination Product.  In the event a Product is sold in a combination
          -------------------                                                  
product with other pharmacologically active components, Net Sales, for purposes
of royalty payments on the combination product, shall be calculated by
multiplying the Net Sales of that combination by the fraction A/B, where A is
the gross selling price of the Product sold separately and B is the gross
selling price of the combination product.  In the event that no such separate
sales are made by Sankyo or a permitted sublicensee, Net Sales for royalty
determination shall be calculated by multiplying Net Sales of the combination by
the fraction C/(C+D) where C is the fully allocated cost of the Product and D is
the fully allocated cost of such other pharmacologically active components. In
no event shall Net Sales of any Product calculated under this Section 7.2 with
respect to any combination product be less than fifty percent of the Net Sales
of such combination product.

                         ROYALTY REPORTS AND ACCOUNTING
                         ------------------------------

     8.1  Reports, Exchange Rates.  During the term of this Agreement following
          -----------------------                                              
the First Commercial Sale of a Product, Sankyo shall furnish to Gensia Sicor a
written quarterly report showing, on a country by country basis, (i) the gross
sales of all Products sold by Sankyo and its sublicensees in the Territory
during the reporting period and the calculation of Net Sales from such gross
sales; (ii) the royalties payable in U.S. dollars, which shall have accrued
hereunder in respect of such sales; (iii) withholding taxes, if any, required by
law to be deducted in respect of such royalties, provided that Sankyo will take
                                                 --------                      
reasonable action to seek to minimize any such withholding taxes; (iv) the dates
of the First Commercial Sales of any Products in any country in the Territory

                                      -19-
<PAGE>
 
during the reporting period; and (v) the exchange rates used in determining the
amount of United States dollars.  For sales which took place outside of the
United States, its territories and possessions, the royalty obligation of Sankyo
shall be determined on the basis of Sankyo's monthly standard account of sales
which shall be interpreted as representing the result of conversion of all local
currency sales to U.S. Dollars at the rate equal to the average of the rate
published in the London Times for the close of business in London on the last
                        -----                                                
business day of each of the three (3) months of the calendar quarter for which
the payments are reported.  Reports shall be due on the thirty-fifth (35th) day
following the close of each respective quarter.  If no royalty is due for any
royalty period hereunder, Sankyo shall so report.  Sankyo shall keep accurate
records in sufficient detail to enable the royalties payable hereunder to be
determined.

     8.2  Audits.
          ------ 

     8.2.1   Upon the written request of Gensia Sicor at Gensia Sicor's expense
and not more than once in each calendar year, Sankyo shall permit an
internationally recognized independent public accountant selected by Gensia
Sicor and reasonably acceptable to Sankyo, to have access during normal business
hours to such of the records of Sankyo as may be reasonably necessary to verify
the accuracy of the royalty reports hereunder in respect of any fiscal year
ending not more than twenty-four (24) months prior to the date of such request.

     8.2.2   In the event such accountant concludes that additional royalties
were owed during such period, the additional royalty shall be paid within thirty
(30) days of the date Gensia Sicor delivers to Sankyo such accountant's written
report so concluding.  The fees charged by such accountant shall be paid by
Gensia Sicor unless the audit discloses that the royalties payable by Sankyo for
the audited period are more than one hundred five percent (105%) of the
royalties actually paid for such period, in which case Sankyo shall pay the
reasonable fees and expenses charged by the accountant.

     8.2.3   Sankyo shall include in each sublicense granted by it pursuant to
this Agreement a provision requiring the sublicensee to make reports to Sankyo,
to keep and maintain records of sales made pursuant to such sublicense and to
grant access to such records by Gensia Sicor's independent accountant to the
same extent required of Sankyo under this Agreement.  Upon the expiration of
twenty-four (24) months following the end of any fiscal year, the calculation of
royalties payable with respect to such year shall be binding and conclusive upon
Gensia Sicor, and Sankyo and its sublicensees shall be released from any
liability or accountability with respect to royalties for such year.

     8.3  Confidential Financial Information.  Gensia Sicor agrees that all
          ----------------------------------                               
information subject to review under this Article 8 or under any sublicense
agreement is confidential and that Gensia

                                      -20-

Sicor shall cause its accountant to retain all such information in confidence.


                                   ARTICLE 9.

                                    PAYMENTS
                                    --------

     9.1  Payment Terms.  Royalties shown to have accrued by each royalty report
          -------------                                                         
provided for under Article 8 of this Agreement shall be due and payable on the
date such royalty report is due.  Payment of royalties in whole or in part may
be made in advance of such due date.  Royalties determined to be owing, and any
overpayments to be credited, with respect to any prior quarter shall be added,
together with interest thereon under Section 9.4 below from the date of the
report for the quarter for which such amounts are owing, or credited, as the
case may be, to the next quarterly payment hereunder.

     9.2  Exchange Control.  Except as hereinafter provided in this Section 9.2,
          ----------------                                                      
all royalties due and other payments hereunder shall be paid in United States
dollars.  If at any time legal restrictions prevent the prompt remittance of
part or all royalties with respect to any country of the Territory where the
product is sold, payment shall be made through such lawful means or methods as
Sankyo may determine.  When in any country the law or regulations prohibit both
the transmittal and deposit of royalties on sales in such a country, royalty
payments shall be suspended for as long as such prohibition is in effect
(provided, however, that such suspended payments shall bear interest at the
- ---------  -------                                                         
initial rate stated in Section 9.4 hereof), and so soon as such prohibition
ceases to be in effect, all royalties that Sankyo or its sublicensees would have
been obligated to transmit or deposit, but for the prohibition, shall forthwith
be deposited or transmitted promptly to the extent allowable, as the case may
be.  If the royalty rate specified in this Agreement should exceed the
permissible rate established in any country, the royalty rate for sales in such
country shall be adjusted to the highest legally permissible or government-
approved rate.

     9.3  Payment Method. Except as provided in Section 9.2, all payments by
          --------------                                                    
Sankyo to Gensia Sicor under this Agreement shall be made by bank wire transfer
in immediately available funds to such account as Gensia Sicor specified to
Sankyo before such payment is due.

     9.4  Late Payments.  Any payments by Sankyo that are not paid within thirty
          -------------                                                         
(30) days of when such payments are due under this Agreement shall bear
interest, to the extent permitted by applicable law, at ten (10) percentage
points above the London Interbank Offered Rate (LIBOR) calculated on the
respective dates such payments are due.

     9.5  Withholding Taxes.
          ----------------- 

     9.5.1   Royalties.  Sankyo may withhold from the royalties due to Gensia
             ---------                                                       
Sicor hereunder amounts for payment of any withholding tax that Sankyo has paid
to any taxing authority with respect to the royalty amounts due to Gensia Sicor
hereunder; provided, however, that the net amount payable to Gensia Sicor for
           --------  -------                                                 
any royalty period shall in no event be reduced by more than ten percent (10%)
of the royalties owing to Gensia Sicor for such royalty period.  Sankyo agrees
to reasonably cooperate with Gensia in obtaining a foreign tax credit in the
United States with respect to such withholding tax on royalties due to Gensia
Sicor hereunder on the sale or manufacture of Products.

     9.5.2   Other Payments.  All amounts payable by Sankyo to Gensia Sicor
             --------------                                                
hereunder, other than royalties due on the sale or manufacture of Products,
represent the actual net proceeds to be received by Gensia Sicor.  Gensia Sicor
agrees to reasonably cooperate with Sankyo in obtaining a refund of any
withholding taxes paid by Sankyo with respect to any such amounts payable to
Gensia Sicor hereunder.  In the event that Gensia is successful in obtaining any
refund of withholding taxes paid by Sankyo with respect to any such amounts
payable to Gensia Sicor hereunder, Gensia agrees to promptly remit the amount of
such refund to Sankyo.

          -------                                                        
Affiliates, shall be named as a defendant in a legal proceeding by a Third Party
for infringement of a patent because of the manufacture, use or sale of Products
or Licensed Compounds (but only to the extent such manufacture, use or sale is
claimed in the Gensia Sicor Patent Rights), the party which has been sued shall
promptly notify the other party in writing of the institution of such suit.  The
party which has been sued may, at its option and at its sole expense, control
and defend such suit.  The controlling party may not settle such suit or
otherwise consent to an adverse judgment in such suit that diminishes the right
or interests of the non-controlling party, or subjects the non-controlling party
to any liability for contribution pursuant to Section 10.3 hereof, without the
express written consent of the non-controlling party.  The party which has been
sued shall keep the other party at all times reasonably informed as to the
status of the suit.  The party which is not controlling such legal proceedings
shall have the right to be represented by advisory counsel of its own selection
(such counsel's opinion shall be reasonably considered by the controlling
party), at its own expense, and shall cooperate fully in the defense of such
suit and furnish to the party controlling such legal proceedings all evidence
and assistance in its control.

     10.2    Defense of Actions Against Gensia Sicor and Sankyo.  If Gensia
             --------------------------------------------------            
Sicor and Sankyo, or any of their respective Affiliates shall be jointly named
as defendants in a legal proceeding by a Third Party or shall be joined in the
same litigation for infringement of a patent because of the manufacture, use or
sale of Products or Licensed Compounds (but only to the extent such manufacture,
use or sale is claimed in the Gensia Sicor Patent Rights), Gensia Sicor shall be
entitled to control the defense of such suit, and all expenses including costs,
attorney fees, adverse judgements or settlement amounts incurred on account of
Sankyo or Gensia Sicor or both shall be paid as set forth under Section 10.3
below.  Sankyo shall have the right to be represented by counsel of its own
selection, but at its sole expense, and shall cooperate fully in the defense of
such suit and furnish to Gensia Sicor all evidence and assistance in its
control.  Gensia Sicor shall, however, not be entitled to settle such suit or
otherwise consent to an adverse judgment in such suit without the express
written consent of Sankyo if such settlement or adverse judgment diminishes any
right or interest of Sankyo hereunder, or subjects Sankyo to any liability for
contribution pursuant to Section 10.3 hereof.

     10.3 Contribution.  With respect to any judgments, settlements or damages
          ------------                                                        
payable with respect to legal proceedings covered by Sections 10.1 and 10.2
above, Gensia Sicor shall contribute an amount, equal to twenty-five percent
(25%) of such judgments, settlements or damages (not to exceed in the aggregate
the amount of royalties actually paid by Sankyo to Gensia Sicor through the date
of such judgment, settlement or damage with respect to the alleged infringing
Product in the country where the legal action was maintained), and Sankyo shall
pay the remainder.  With respect to any legal proceedings covered by Section
10.2 above, Gensia Sicor may deduct the actual expenses paid by Gensia Sicor in
such suit, including costs, attorney fees, advance judgments or settlement
amounts, for the purpose of determining the amount of its contribution under the
previous sentence.

and for a period of five (5) years thereafter, both parties shall maintain in
confidence and use only for purposes of this Agreement confidential information
and data, received from the other party, resulting from or related to the
development of Research Compounds or Products.

     For purposes of this Article 11, information and data described above shall
be referred to as "Information."  To the extent it is reasonably necessary or
appropriate to fulfill its obligations or exercise its rights under this

Section not to disclose to its Affiliates, sublicensees, consultants, outside
contractors and clinical investigators, on a need-to-know basis on condition
that such entities or persons agree to keep the Information confidential for the
same time periods and to the same extent as such party is required to keep the
Information confidential; and a party or its sublicensees may disclose such
Information to government or other regulatory authorities to the extent that
such disclosure is reasonably necessary to obtain patents or authorizations to
conduct clinical trials with and to commercially market the Product.  The
obligation not to disclose Information shall not apply to any party of such
Information that (i) is or becomes patented, published or otherwise part of the
public domain other than by acts of the party obligated not to disclose such
Information or its Affiliates or sublicensees in contravention of this
Agreement; or (ii) is disclosed to the receiving party or its Affiliates or
sublicensees by a Third Party, provided such Information was not obtained by

disclose any terms or conditions of this Agreement to any Third Party without
the prior consent of the other party, except as required by applicable law or to
persons with whom Sankyo or Gensia Sicor has entered into or proposes to enter
into a business relationship.  Notwithstanding the foregoing, prior to execution
of this Agreement, Sankyo and Gensia Sicor shall agree upon the substance of
information that can be used to describe the terms of this transaction, and
Sankyo and Gensia Sicor may disclose such information, as modified by mutual
agreement from time to time, without the other party's consent.

     12.1 During the terms of this Agreement, Gensia Sicor and Sankyo each
acknowledge the other party's interest in publishing certain of its results to
obtain recognition within the scientific community and to advance the state of
scientific knowledge.  Each party also recognizes the mutual interest in
obtaining valid patent protection.  Consequently, either party, its employees or
consultants wishing to make a publication (including any oral disclosure made
without obligation of confidentiality) relating to work performed by such party
as part of the Research Program (the "Publishing Party") shall transmit to the
other party (the "Reviewing Party") a copy of the proposed written publication
at

                                      -24-

such oral disclosure at least thirty (30) days prior to submission of the
abstract or the oral disclosure, which ever is earlier.  The Reviewing Party
shall have the right (a) to propose modifications to the publication for patent
reasons, (b) to request a delay in publication or presentation in order to
protect patentable information and (c) to propose modifications to the
publication to protect valuable know-how and technology of the Receiving Party.

     If the Reviewing Party requests such a delay, the Publishing Party shall
delay submission or presentation of the publication for a period of ninety (90)
days to enable patent applications protecting each party's rights in such
information to be filed in accordance with Article 13 below.  Upon the expiry of
sixty (60) days, in the case of proposed written disclosures, or thirty (30)
days, in the case of an abstract of proposed oral disclosures, from transmission
of such proposed disclosures to the Reviewing Party, the Publishing Party shall
be free to proceed with the written publication or the oral presentation,
respectively, unless the Reviewing Party has requested the delay described
above.

promptly disclose to the other party the making, conception or reduction to
practice of Inventions by employees or others acting on behalf of such party.
Each party represents and agrees that, all employees and other persons acting on
its behalf in performing its obligations under this Agreement shall be obligated
under a binding written agreement to assign to such party or as such party shall
direct, all Inventions made or conceived by such employee or other person, or in
the case of non-employees working for other companies or institutions on behalf
of Gensia Sicor or Sankyo; Gensia Sicor or Sankyo, as applicable, shall have the
right to license all Inventions made by such non-employees on behalf of Gensia
Sicor or Sankyo, as applicable, in accordance with the policies of said company
or institution.  Gensia Sicor and Sankyo

promptly shall file a United States priority patent application, and, in the
case of a Joint Invention, shall assign such patent application jointly to
Sankyo and Gensia Sicor.  When a Sankyo Invention has been made which may
reasonably be considered to be patentable, Sankyo promptly shall file a Japanese
priority patent application.  Gensia Sicor shall give Sankyo an opportunity to
review the text of an application for a Joint Invention before filing, and shall
supply Sankyo with a copy of the application as filed, together with a note of
its filing date and serial number.

13.2.1 above, the parties shall consult together, through the Steering Committee
or otherwise, and agree whether such priority application should be abandoned
without replacement; abandoned and refiled; proceeded within the country of
filing only; or used as the basis for a claim of priority under the Paris
Convention for corresponding applications in other countries.

     13.2.3  Prosecution and Maintenance.
             --------------------------- 

     (a) Gensia Sicor shall control the preparation, filing, prosecution and
maintenance of all patent applications and patents which claim Gensia Sicor

     13.3 Cooperation.  Each party shall make available to the other party or
          -----------                                                        
its authorized attorneys, agents or representatives, its employees, agents or
consultants necessary or appropriate to enable the appropriate party to file,
prosecute and maintain patent applications and resulting patents with respect to
Inventions for

                                      -26-
<PAGE>
 
a period of time sufficient for such party to obtain the assistance it needs
from such personnel.  Where appropriate, each party shall sign or cause to have
signed all documents relating to said patent applications or patents at no
charge to the other.

     13.4 No Other Technology Rights.  Except as otherwise provided in this
          --------------------------                                       
Agreement, under no circumstances shall a party hereto, as a result of this
Agreement, obtain any ownership interest or other right in any technology, know-
how, patents, pending patent applications, products, vaccines, antibodies, cell
lines or cultures, or animals of the other party, including items owned,
controlled or developed by the other, or transferred by the other to said party
at any time pursuant to this Agreement.  It is understood and agreed by the
parties that this Agreement does not grant to either party any license or other
right in basic technology of the other party except to the extent necessary to
enable the parties to carry out their party of this Agreement.

     13.5 Enforcement of Patent Rights.
          ---------------------------- 

     13.5.1  Gensia Sicor and Sankyo shall promptly notify the other in writing
of any alleged or threatened infringement of Patent Rights in the Field of which
they become aware.  The Parties shall then confer and may agree jointly to
prosecute any infringement described in this Section 13.5.  The party owning the
Patent alleged or threatened to be infringed shall control the joint litigation
in the event of any dispute between the parties with respect to any aspect of
the litigation.  With respect to Joint Inventions, Gensia Sicor shall control
such joint litigation.

     13.5.2  If the parties do not agree on whether or how to proceed with
enforcement activity within (i) ninety (90) days following the notice of alleged
infringement or (ii) ten (10) days before the time limit, if any, set forth in
the appropriate laws and regulations for the filing of such actions, whichever
comes first, then either party may act in its own name to commence litigation
with respect to the alleged or threatened infringement.  The non-controlling
party shall reasonably cooperate with the party bringing such enforcement
action, at the sole expense of the party bringing such enforcement action.

     13.5.3  In the event a party brings an infringement action, the other party
shall reasonably cooperate, including, if required to bring such action, the
furnishing of a power of attorney.  Neither party shall have the right to settle
any patent infringement litigation under this Section 13.5 in a manner that
diminishes the rights or interests of the other party without the express
written consent of such other party.

     13.5.4  The costs of any joint litigation commenced pursuant to Section
13.5.1, including attorneys' fees and expenses, shall be borne equally by the
parties (unless they agree to a different cost sharing arrangement in any
particular matter), with such costs to be accounted for by equalizing payments
to be made on a quarterly

                                      -27-
<PAGE>
 
basis.  Only out-of-pocket costs shall be accounted for and reimbursed under
this Section 13.5.4, without an allocation for internal resources devoted to the
litigation.  The costs of any sole litigation commenced pursuant to Section
13.5.2, including attorneys' fees and expenses, shall be borne solely by the
party bringing such infringement action.

     13.5.5  Except as otherwise agreed to by the parties as part of a cost
sharing arrangement, any recovery realized as a result of any joint litigation
commenced pursuant to Section 13.5.1 shall be shared equally by the parties
(unless they agree beforehand to a different sharing of such recovery).  Any
recovery realized as a result of any sole litigation commenced pursuant to
Section 13.5.2 shall be retained by the party bringing such infringement action.

                               TERM, TERMINATION

          ---------------------                                                 
the occurrence of any of the following:

     14.2.1  Upon written notice by one party to the other, if the other party
files or has filed against it a petition under the Bankruptcy Act, makes an
assignment for the benefit of creditors, has a receiver appointed for it or any
of its assets, provided that, notwithstanding anything herein to the contrary, a
               --------                                                         
party shall not be able to terminate this Agreement pursuant to this Section
14.2.1 for any period during which the other party is proceeding in good faith
to reorganize under Chapter 11 of the United States Bankruptcy Code.  In the
event Sankyo terminates this Agreement pursuant to this Section 14.2.1, Sankyo
shall retain all rights to make, have made, use and sell the Products, subject

shall give to the defaulting party written notice (the "Notice of Default")
specifying the nature of the Default and requesting that the defaulting party
cures such Default within one hundred eighty (180) days.  If the defaulting
party shall dispute the existence, extent or nature of any Default set forth in
a Notice of Default, the parties shall use good faith efforts to resolve the
dispute.  In the event any Default shall not be cured within one hundred eighty
(180) days of the defaulting party's receipt of a Notice of Default, the non-
defaulting party shall be entitled to terminate this Agreement in its entirety
and

the parties have conferred as provided in Section 20.2.2 hereof.

     (a) If the non-defaulting party under this Section 14.2.2 is Sankyo, Sankyo
shall retain (i) all rights under this Agreement and any License Agreements to
make, have made, use and sell all Licensed Compounds and Products incorporating
such Licensed Compounds in accordance with the terms hereof and thereof, and
(ii) all rights under this Agreement with respect to all Recommended Compounds
that are identified in the most recent Steering Committee minutes, and all
Candidate Compounds, in accordance with the terms hereof, subject to the payment
to Gensia Sicor of royalties and other amounts under the terms and conditions
set forth in this Agreement; provided, however, that such payment to Gensia
                             --------  -------                             
Sicor shall be at one-half (1/2) the rates set forth in Section 7.1.1 hereof in
the event of Gensia Sicor's default.

     (b) If the non-defaulting party under this Section 14.2.2 is Gensia Sicor,
all rights to compounds shall revert to Gensia Sicor if such compounds were
Gensia Sicor compounds or Third Party Compounds or revert to Sankyo if such
compounds were Sankyo compounds (subject to the restrictions set forth in
Section 4.6 hereof).

          ---------------------                                              
shall not relieve the parties of any obligation accruing prior to such
expiration or termination and the provisions of Section 4.2, 4.3, 4.4, 4.6 and
7.4, and Article 11, 12 and 15 shall survive the expiration of this Agreement.
Upon the termination of the Research Program, (i) Sankyo's obligation to fund
the Research Program pursuant to Section 3.3 hereof shall terminate; and (ii)
for so long as at least one (1) Licensed Compound is in development, all
Licensed Compounds and Products resulting therefrom shall continue to be

                                   ---------

     15.1 Sankyo Indemnity Obligations.  Sankyo agrees to defend, indemnify and
          ----------------------------                                         
hold Gensia Sicor, Gensia Sicor's Affiliates and their directors, officers,
employees and agents harmless from all losses, liabilities, damages and expenses
(including reasonable attorneys' fees and costs) incurred as a result of any
claim, demand, action, or other proceeding by any Third Party arising as a
result of (a) breach of representation or warranty by Sankyo; (b) breach of any
of its obligations under this Agreement by Sankyo; (c) actual or asserted
violations of any applicable law or regulation by Sankyo, its Affiliates or
sublicensees by virtue of which Products manufactured, distributed or sold by

adulterated, misbranded, mislabeled or otherwise not in compliance with any
applicable law or regulation; (d) bodily injury, death or property damage
attributable to the manufacture, distribution, sale or use of Products by
Sankyo, its Affiliates or sublicensees or otherwise attributable to a Product
manufactured in accordance with specifications provided by Sankyo; or (e)
Product recall ordered by a governmental agency, or required by a confirmed
Product failure as reasonably determined by the parties hereto, with respect to
a Product manufactured by Sankyo, its Affiliates or sublicensees; in each case
except to the extent such loss, liability, damage or expense was attributable to
Gensia Sicor's gross negligence or willful misconduct.

     15.2 Gensia Sicor Indemnity Obligations.  Gensia Sicor agrees to defend,
          ----------------------------------                                 
indemnify and hold Sankyo, Sankyo's Affiliates and their directors, officers,
employees and agents harmless from all losses, liabilities, damages and expenses
(including reasonable attorneys' fees and costs) incurred as a result of any
claim, demand, action, or other proceeding by any Third Party arising as a
result of (a) breach of representation or warranty by Gensia Sicor; (b) breach
of any of its obligations under this Agreement by Gensia Sicor; (c) actual or
asserted violations of any applicable law or regulation by Gensia Sicor, its
Affiliates or licensees (other than Sankyo, its Affiliates or sublicensees) by
virtue of which Products manufactured, distributed or sold by Gensia Sicor, its
Affiliates or licensees (other than Sankyo, its Affiliates or sublicensees)
shall be alleged or determined to be adulterated, misbranded, mislabeled or
otherwise not in compliance with any applicable law or regulation; (d) bodily
injury, death or property damage attributable to the manufacture of Products by
Gensia Sicor, its Affiliates or licensees (other than Sankyo, its Affiliates or
sublicensees), unless manufactured in accordance with specifications provided by
Sankyo; or (e) Product recall ordered by a governmental agency, or required by a
confirmed Product failure as reasonably determined by the parties hereto, with
respect to a Product manufactured by Gensia Sicor, its Affiliates or licensees
(other than Sankyo, its Affiliates or sublicensees), unless manufactured in
accordance with specifications provided by Sankyo; in each case except to the
extent such loss, liability, damage or expense was attributable to Sankyo's
gross negligence or willful misconduct.

     15.3 Procedure.  A party or any of its Affiliates or their employees or
          ---------                                                         
agents (the "Indemnitee") that intends to claim indemnification under this
Article 15 shall promptly notify the other party (the "Indemnitor") of any loss,
claim, damage, liability or action in respect of which the Indemnitee intends to
claim such indemnification, and the Indemnitor shall assume the defense thereof
with counsel mutually satisfactory to the parties; provided, however, that an
                                                   --------  -------         
Indemnitee shall have the right to retain its own counsel, with the fees and
expenses to be paid by the Indemnitor, if representation of such Indemnitee by
the counsel retained by the Indemnitor would be inappropriate due to actual or
potential differing interests between such Indemnitee and any other

                                      -30-
<PAGE>
 
party represented by such counsel in such proceedings.  The indemnity agreement
in this Article 15 shall not apply to amounts paid in settlement of any loss,
claim, damage, liability or action if such settlement is effected without the
consent of the Indemnitor, which consent shall not be withheld unreasonably.
The failure to deliver notice to the Indemnitor within a reasonable time after
the commencement of any such action, if prejudicial to its ability to defend
such action, shall relieve such Indemnitor of any liability to the Indemnitee
under this Article 15, but the omission so to deliver notice to the Indemnitor
will not relieve it of any liability that it may have to any Indemnitee
otherwise than under this Article 15.  The Indemnitee under this Article 15, its
employees and agents, shall cooperate fully with the Indemnitor and its legal
representatives in the investigation of any action, claim or liability covered
by this indemnification.  In the event that each party claims indemnity from the
other and one party is finally held liable to indemnify the other, the
Indemnitor shall additionally be liable to pay the reasonable legal costs and
attorneys' fees incurred by the Indemnitee in establishing its claim for
indemnity.

     15.4 Insurance.  Sankyo and Gensia Sicor shall each maintain product
          ---------                                                      
liability insurance with respect to development, manufacture and sales of
Products by Sankyo or Gensia Sicor, respectively, in such amount as Sankyo or
Gensia Sicor, respectively, customarily maintains with respect to the
development, manufacture and sales of its other products.  Sankyo or Gensia
Sicor, as applicable, shall maintain such insurance for so long as it continues
to develop, manufacture or sell any Products, and thereafter for so long as
Sankyo or Gensia Sicor, as applicable, customarily maintains insurance for
itself covering the development, manufacture or sale of its other products.

     Neither party shall be held liable or responsible to the other party nor be
deemed to have defaulted under or breached this Agreement for failure or delay
in fulfilling or performing any term of this Agreement when such failure or
delay is caused by or results from causes beyond the reasonable control of the
affected party including but not limited to fire, floods, embargoes, war, acts
of war (whether war be declared or not), insurrections, riots, civil commotions,
strikes, lockouts or other labor disturbances, acts of God or acts, omissions or
delays in acting by any governmental authority or the other party.

                                  ----------

       This Agreement may not be assigned or otherwise transferred by either
party without the consent of the other party; provided, however, that either
                                              --------  -------             
Gensia Sicor or Sankyo may, without such consent, assign this Agreement and its
rights and obligations hereunder to its Affiliates or in connection with the
transfer or sale of all or substantially all of its business to which this
Agreement pertains, or in the event of its merger or consolidation or change in
control or similar transaction.  Any purported assignment in violation of the
preceding sentences shall be void.  Any permitted assignee shall assume all
obligations of its assignor under this Agreement.  Notwithstanding the
foregoing, in the event of a merger, consolidation, change of control or similar
transaction by Gensia Sicor, Sankyo shall not be required to provide to Gensia
Sicor's successor the information described in Sections 4.3 and 5.5 hereof if,
in Sankyo's reasonable judgment, the provision of such information to such
successor could cause material competitive harm to Sankyo.


                                  ARTICLE 18.

                    NOTIFICATION OF PATENT TERM RESTORATION
                    ---------------------------------------

     Gensia Sicor shall notify Sankyo of (i) the issuance of each United States
patent included within the Patent Rights, giving the date of issue and patent
number for each such patent, and (ii) each notice pertaining to any patent
included within the Patent Rights which it receives as patent owner pursuant to
the Drug Price Competition and Patent Term Restoration Act of 1984 (the "Act"),
including notices pursuant to sections 101 and 103 of the Act from persons who
have filed an abbreviated NDA.  Such notices shall be given promptly, but in any
event within fifteen (15) calendar days of each such patent's date of issue or
receipt of each such notice pursuant to the Act, whichever is applicable.
Gensia Sicor shall notify Sankyo of each filing for patent term restoration
under the Act, any allegations of failure to show due diligence and all awards
of patent term restoration (extensions) with respect to the Patent Rights.
Likewise, Sankyo will inform Gensia Sicor of patent extensions and periods of
data exclusivity in the rest of the world regarding any Product.

                                  SEVERABILITY
                                  ------------

     Each party hereby agrees that it does not intend to violate any public
policy, statutory or common laws, rules, regulations, treaty or decision of any
government agency or executive body thereof of any country or community or
association of countries.

Should one or more provisions of this Agreement be or become invalid, the
parties hereto shall substitute, by mutual consent, valid provisions for such
invalid provisions which valid provisions in their economic effect are
sufficiently similar to the invalid provisions that it can be reasonably assumed
that the parties would have entered into this Agreement with such valid
provisions.  In case such valid provisions cannot be agreed upon, the invalidity
of one or several provisions of this Agreement shall not affect the validity of
this Agreement as a whole, unless the invalid provisions are of such essential
importance to this Agreement that it is to be reasonably assumed that the
parties would not have entered into this Agreement without the invalid
provisions.

chief executive officers cannot promptly resolve such disputes, then such

via San Salvatore 7, LUGANO 6902, Switzerland; hereinafter referred to as ALCO,

SICOR - SOCIETA' ITALIANA CORTICOSTEROIDI SPA an Italian company with offices at
Via Terrazzano 77, RHO (Milan), Italy; hereinafter referred to as SICOR

                                      and


BOEHRINGER INGELHEIM INTERNATIONAL GmbH with its principal office address at

Now, therefore, in consideration of the premises and the mutual covenants
hereinafter provided for, the parties agree as follows:

1.  Purpose - The purpose of this Agreement is to define the terms and
    -------                                                           
conditions under which SICOR and ALCO agree to manufacture and sell

agrees to buy [CONFIDENTIAL TREATMENT REQUESTED] from ALCO.

                                      1/11
<PAGE>
 
2. Specifications, DMF and Manufacturing Methods - [CONFIDENTIAL TREATMENT
    ---------------------------------------------                       
REQUESTED] means the unmicronised compound meeting the specifications given in
Appendix I hereto (hereinafter called "Specifications").

SICOR shall provide BOEHRINGER with the open part of a DMF for BOEHRINGER's use
in any country of the world.

In case any health administration or governmental authority in any country will
ask BOEHRINGER for additional information concerning [CONFIDENTIAL TREATMENT
REQUESTED] (e.g. about the closed part of a DMF) SICOR undertakes, either
directly or through ALCO, to promptly pass such information to the respective
administration or other authority.

For the term of this Agreement, SICOR shall not change any Specifications,
manufacturing methods (given in Appendix II) or site of manufacture for the
[CONFIDENTIAL TREATMENT REQUESTED] supplied to BOEHRINGER hereunder without
BOEHRINGER's prior written consent to any such changes, provided that SICOR may
                                                        --------
make such changes without BOEHRINGER's consent where so required by the relevant
Health Authorities and/or if necessary to maintain any Pharmacopoeia standards
as set forth in Appendix I.

The site of manufacture for the [CONFIDENTIAL TREATMENT REQUESTED] supplied
hereunder may be either SICOR's facilities or the facilities of SINTESIS LERMA,
S.A. de C.V., a Mexican corporation with its principal place of business at Av.
San Rafael No. 35, Parque Industrial Lerma, Lerma de Villada, E.do Mexico,
Mexico ("LERMA"), who would produce such [CONFIDENTIAL TREATMENT REQUESTED]
under a toll manufacturing arrangement with SICOR.

SICOR shall undertake to enter into a toll manufacturing agreement for
[CONFIDENTIAL TREATMENT REQUESTED] with LERMA upon LERMA's receiving approval
from the United States Food and Drug Administration as a facility for the
manufacture of bulk active ingredients for use in the United States. In any such
toll manufacturing agreement with LERMA, SICOR undertakes to ensure that LERMA
fulfills all the obligations of SICOR concerning [CONFIDENTIAL TREATMENT
REQUESTED] supplied hereunder which should be met by LERMA so as to give effect
to said SICOR obligations, including but not limited to SICOR's obligations with
regards to the open part of the [CONFIDENTIAL TREATMENT REQUESTED] DMF (but
which, in a toll manufacturing agreement, would require the filing of change of
site applications) and other regulatory information, manufacturing methods and
specifications. SICOR shall also undertake to ensure that in such agreement,
LERMA will use its best efforts to supply as fast as possible to the relevant
Health Authorities all the documentation necessary for manufacturing
[CONFIDENTIAL TREATMENT REQUESTED] for SICOR, which [CONFIDENTIAL TREATMENT
REQUESTED] is to be provided by SICOR hereunder. However, the parties agree that
the [CONFIDENTIAL TREATMENT REQUESTED] delivered to BOEHRINGER under this
Agreement will in general be manufactured by SICOR and LERMA shall only be
appointed as a second source to cover any force majeure situations.

                                      2/11

3.  Preferential dealing - As long as the price and quality terms and conditions
    --------------------                                                        
hereunder are met, BOEHRINGER agrees to make ALCO and SICOR its first choice as
supplier of [CONFIDENTIAL TREATMENT REQUESTED]. In this sense, BOEHRINGER shall
purchase all its requirements of [CONFIDENTIAL TREATMENT REQUESTED] for the
production and use of clinical samples containing [CONFIDENTIAL TREATMENT
REQUESTED] for potential repetitions of clinical trials, and for the production
and sales of the Products in case these Products will be registered,
preferentially from ALCO for the term of this Agreement, and ALCO and SICOR
through ALCO to supply to BOEHRINGER all such requirements of [CONFIDENTIAL
TREATMENT REQUESTED].

Should another party offer BOEHRINGER an equivalent quality of [CONFIDENTIAL
TREATMENT REQUESTED] at a lower price or at more favourable conditions and ALCO
is not prepared to accept this offer by providing [CONFIDENTIAL TREATMENT
REQUESTED] at a price equal to the price offered by that other party within four
(4) weeks of BOEHRINGER's informing ALCO of said lower price or more favourable
conditions, then BOEHRINGER is exempted from its obligation to purchase
[CONFIDENTIAL TREATMENT REQUESTED] from ALCO for the quantities of [CONFIDENTIAL
TREATMENT REQUESTED] offered at such lower price or more favourable conditions.

However, in view of cost and burden to be incurred for re-registration,
BOEHRINGER is willing to accept a price up five percent (5%) above the price
offered by that other party.

For the purposes of this Agreement, the quality of [CONFIDENTIAL TREATMENT
REQUESTED] shall be considered equivalent if and only if:

     - the other party offering such lower prices or more favourable conditions
     for [CONFIDENTIAL TREATMENT REQUESTED] has the capacity, manufacturing
     facilities, and rights to intellectual/industrial property necessary and
     sufficient to be a reasonably reliable supplier of [CONFIDENTIAL TREATMENT
     REQUESTED] over the term of this Agreement;

     - the other party offering such lower prices or more favourable conditions
     for [CONFIDENTIAL TREATMENT REQUESTED] has been approved or BOEHRINGER can
     demonstrate that said other party will be approved as a manufacturing
     facility for bulk active ingredients by the appropriate regulatory
     authorities of the country or countries in which BOEHRINGER intends to sell
     products containing [CONFIDENTIAL TREATMENT REQUESTED] to be purchased from
     that other party; and

     - any such [CONFIDENTIAL TREATMENT REQUESTED] offered by the other party
     would meet the BOEHRINGER quality requirements, and would comply with the
     same governmental regulations and manufacturing practices, and meet the
     same standards, as those complied with and met by SICOR in under this
     Agreement for the country or countries in which BOEHRINGER intends to sell
     products containing [CONFIDENTIAL TREATMENT REQUESTED] to be purchased from
     that other party.

                                      3/11
<PAGE>
 
In case [CONFIDENTIAL TREATMENT REQUESTED] which meets all the requirements
stated above is offered to BOEHRINGER, BOEHRINGER will inform ALCO of that fact
and of the prices and conditions of this offer. In order to prove the existence
of a competitive order BOEHRINGER undertakes, if required by ALCO and/or SICOR,
to provide information regarding the requirements listed above to an auditor
bound to secrecy. The auditor shall not reveal the identity of the competitive
supplier to ALCO or to SICOR.

The costs of such an auditing shall be borne by ALCO and/or SICOR.

ALCO shall grant to BOEHRINGER the lowest price offered by ALCO to any third
party solely for BOEHRINGER's intended sales in the country or countries in
which that third party or its client(s) sell products containing [CONFIDENTIAL
TREATMENT REQUESTED], unless special circumstances justify this price being
                      ------
granted to that third party. For purposes of this Agreement, such special
circumstances can mean, among other circumstances, the requirement of higher
quantities of [CONFIDENTIAL TREATMENT REQUESTED] or an individual supply of
[CONFIDENTIAL TREATMENT REQUESTED] without any further support by ALCO and/or
SICOR.

In case ALCO intends to offer a lower price to a third party in accordance with
the special circumstances mentioned above, BOEHRINGER shall be informed
promptly.

4.  Price and Delivery Terms - With regard to the cumulative quantities sold in
    ------------------------                                                   
any calendar year, the price for [CONFIDENTIAL TREATMENT REQUESTED] supplied
thereunder through December 31, 1998 during any calendar year shall be:

 50 kgs or less                  [CONFIDENTIAL TREATMENT REQUESTED]    
 50.001 kgs through 100 kgs      [CONFIDENTIAL TREATMENT REQUESTED]    
 100.001 kgs through 200 kgs     [CONFIDENTIAL TREATMENT REQUESTED]    
 200.001 kgs through 300 kgs     [CONFIDENTIAL TREATMENT REQUESTED]    
 greater than 300 kgs            [CONFIDENTIAL TREATMENT REQUESTED]    
                                    

for [CONFIDENTIAL TREATMENT REQUESTED] delivered by ALCO to BOEHRINGER DDU
(Incoterms 1990) named destination, payment terms thirty (30) days net after
receipt of the invoice.

No later than October 1 1998 and each October 1st thereafter during the term of
this Agreement, the price of [CONFIDENTIAL TREATMENT REQUESTED] for the
following year shall be negotiated in good faith and timely manner between ALCO
and BOEHRINGER. Increases of pricesshall only be negotiated in case of increase
in the cost due to an increase in labour, overhead and/or raw materials
exceeding five per cent (5%). SICOR or ALCO for SICOR will provide to BOEHRINGER
adequate evidence of such developments.

If BOEHRINGER can demonstrate to ALCO that the price does not allow BOEHRINGER
to make reasonable sales of its Products

                                      4/11
<PAGE>
 
containing [CONFIDENTIAL TREATMENT REQUESTED] in a reasonable number of its
markets, ALCO and BOEHRINGER shall discuss in good faith negotiations a new
price to be applied hereunder for said markets.

If ALCO and BOEHRINGER do not reach an agreement at such time, then BOEHRINGER
is exempted from its obligation to purchase for the said markets.

5.  Forecasts and order procedure - At the end of each March, June, September
    -----------------------------
and December hereafter throughout the term of this Agreement, BOEHRINGER shall
provide to SICOR through ALCO an updated forecast of its anticipated overall
requirements of [CONFIDENTIAL TREATMENT REQUESTED] for the following twelve (12)
month period, and its anticipated requirements for the United States and Canada
for the following twelve (12) month period. These forecasts shall be non-binding
estimates except as indicated in the following paragraph.

BOEHRINGER shall order [CONFIDENTIAL TREATMENT REQUESTED] from ALCO by written
purchase orders with a lead time of three (3) months. In the case of unexpected
demand ALCO and SICOR shall make every effort to satisfy BOEHRINGER's
requirements. Notwithstanding the foregoing, ALCO shall not be obligated to
accept any order to the extent that it results in ALCO's having to supply
[CONFIDENTIAL TREATMENT REQUESTED] in excess of one hundred twenty-five percent
(125%) of the first twelve month overall forecast given by BOEHRINGER here-
under--within which falls the date of such order. In such case, ALCO and SICOR
shall nonetheless make all commercially reasonable efforts to comply with such
unplanned changes, but shall not be held liable for their inability to do so.

SICOR agrees to hold a Delivery Stock of [CONFIDENTIAL TREATMENT REQUESTED] at
its premises for future delivery to BOEHRINGER, under the following terms and
conditions:

     - The quantities of [CONFIDENTIAL TREATMENT REQUESTED] to be held in stock
     shall not be less than the greater of the following:

          i) 50% of the most recent twelve (12) month rolling overall forecast
          received by SICOR through ALCO pursuant to the first paragraph of this
          Article 5; or

          ii) 100% of the most recent twelve (12) month rolling forecast for the
          United States and Canada received by SICOR through ALCO pursuant to
          the first paragraph of this Article 5;

provided, however, that SICOR shall not be required to have in said Delivery
- --------                                                                    
Stock at any one time more than one hundred fifty (150) kilograms of
[CONFIDENTIAL TREATMENT REQUESTED] at any one time.

- - Notwithstanding the foregoing, SICOR shall be permitted ninety (90) days from
the date any [CONFIDENTIAL TREATMENT REQUESTED] ordered hereunder leaves its
facilities to replenish the Delivery Stock to the required

                                      5/11
<PAGE>
 
minimum levels in cases of force majeure (as set forth in Article 8) or in case
of orders resulting in SICOR and ALCO having to supply an amount in excess of
the first twelve month overall forecast given by BOEHRINGER hereunder within
which falls the date of such order.  For all other orders, SICOR shall proceed
immediately to replenish the Delivery Stock.

- - For each order accepted hereunder, SICOR shall withdraw from the Delivery
Stock those batches of [CONFIDENTIAL TREATMENT REQUESTED] which would result in
SICOR supplying the earliest produced batches in the Delivery Stock.

6. Warranty and Inability to supply - If SICOR fails to manufacture
   --------------------------------
[CONFIDENTIAL TREATMENT REQUESTED] for supply hereunder and/or ALCO fails to
deliver [CONFIDENTIAL TREATMENT REQUESTED] to BOEHRINGER according to the
Specifications set out in Appendix I, then SICOR shall manufacture and/or ALCO
shall deliver, at SICOR or ALCO's own expense or at SICOR and ALCO's expense and
as soon as possible, [CONFIDENTIAL TREATMENT REQUESTED] which meets the
Specifications set out in Appendix I so as to replace the quantity which did not
meet these requirements and Specifications, and ALCO and SICOR shall deal with
this matter according to the terms and conditions of any then valid distribution
agreement for [CONFIDENTIAL TREATMENT REQUESTED] between the two parties.

Except for orders exceeding one hundred twenty-five percent (125%) of
BOEHRINGER's forecast as set forth in the second paragraph of Article 5, in the
event that SICOR and/or ALCO is unable to meet orders or is only able to meet
partial orders for reasons other than those set forth in the force majeure
                                                             -------------
provision in Article 8 of this Agreement, BOEHRINGER shall have the option of
purchasing the remaining quantity of [CONFIDENTIAL TREATMENT REQUESTED] ordered
that calendar year from a third party, and shall be free to claim damages for
such non-performance from the directly responsible party or parties.

7. Right of Inspection - So as to permit the inspection of [CONFIDENTIAL
   -------------------                                               
TREATMENT REQUESTED] production, SICOR shall allow the representatives of
BOEHRINGER to visit, no more than twice a year, during normal working hours and
upon reasonable prior written notice, those premises of SICOR where
[CONFIDENTIAL TREATMENT REQUESTED] is being produced, stored and/or analysed,
and SICOR shall grant said representatives access to such premises and to
documentation necessary for the production, storage and quality control of the
[CONFIDENTIAL TREATMENT REQUESTED], said documentation not to include, however,
individual batch records for [CONFIDENTIAL TREATMENT REQUESTED] production. The
responsible authorities shall be granted the right of inspection at any time
they choose provided, however, such visit is announced beforehand.

8. Force Majeure - Except with respect to the payment of any monies due
   -------------                                                       
hereunder, a party shall not be held liable to the other for failure to perform
or fulfill an obligation required of the party to the extent such is prevented
by force majeure including, but not limited to, acts of God, fire, delays caused
by suppliers of materials or products, industrial disputes,

                                      6/11
<PAGE>
 
technical problems or disturbances, natural disasters, wars declared or
undeclared, civil strike, embargo, lack of failure of transport facilities,
currency restrictions, or events caused by legislation, regulations, or orders
by any government or governmental agency or by any other supervening
circumstances beyond the control of either party provided, however, that the
force majeure is limited to a period of three (3) months.

9.  Confidentiality - ALCO and SICOR undertake to use all information named
    ---------------
hereunder and received from or through BOEHRINGER only for the purpose of
manufacturing and selling [CONFIDENTIAL TREATMENT REQUESTED] to BOEHRINGER.
BOEHRINGER undertakes to use all information named hereunder and received from
or through ALCO or SICOR, and in particular during any Inspections pursuant to
the provisions of Article 7 of this Agreement, only for the purpose of
purchasing [CONFIDENTIAL TREATMENT REQUESTED] from SICOR through ALCO or of
manufacturing any Products containing [CONFIDENTIAL TREATMENT REQUESTED]. All
parties hereto guarantee to treat as confidential all documents, details,
information and experience of proprietary nature to the other parties regarding
[CONFIDENTIAL TREATMENT REQUESTED] under this Agreement, especially concerning
such know-how, knowledge, information and formulas that has come to the
knowledge of the party at any stage in connection with this Agreement.

The parties agree not to use any such documents, details, information and
experience proprietary to one of the other parties, for any other purpose than
the proper fulfillment of this Agreement, nor to reveal any such documents,
details, information and experience proprietary another party or parties hereto,
to any outsider and/or unauthorized person(s), unless such information has
become public knowledge for reasons for which that party (or someone for whom
that party is responsible) cannot be held liable, unless that other party or
parties, gives its or their consent thereto separately in writing.  For the
purposes hereof all parties hereto shall also be liable for the due observation
of these provisions of confidentiality by any employees of that party, and by
any subcontractor, agent etc. acting for on behalf of that party.

10.  Process Patent Rights - SICOR's process for manufacturing [CONFIDENTIAL
     ---------------------                                                   
TREATMENT REQUESTED]may make use of an invention or inventions claimed in the
European Patent Application [CONFIDENTIAL TREATMENT REQUESTED] and corresponding
patents/patent applications (together, the "Process Patents").

SICOR has a non-exclusive right to use all inventions claimed in the Process
Patents for the life of said Process Patents, which license was granted by AB
Astra under Swedish law in the same agreement in which SICOR transferred
ownership of said Process Patents to AB Astra.

Termination of said agreement, and thus of the license granted thereunder, is
not possible by SICOR nor by AB Astra to the extent that SICOR has transferred
to Astra AB proper title to the Process Patents.

                                      7/11
<PAGE>
 
  SICOR hereby represents that one remaining patent in the family of Process
Patents [CONFIDENTIAL TREATMENT REQUESTED] is still in the process of being
assigned by SICOR to AB Astra, while SICOR has duly assigned by the means and
manner requested by AB Astra all other patents in said family, including but not
limited to the Italian [CONFIDENTIAL TREATMENT REQUESTED] applied for through
the European Patent Organization.

SICOR in addition represents that AB Astra is obliged to use its best endeavors
to prosecute, maintain and defend Process Patents or, in the event that AB Astra
decides to abstain from prosecuting, maintaining or defending any such Process
Patents, to transfer back to SICOR any and all rights to these Process Patents.

To the best of SICOR's and ALCO's knowledge, unless and, in such case, with the
sole exception of Astra AB having maintained its opposition to the Canadian
family member of the Process Patents, which patent is included among those duly
assigned to AB Astra by the means and manner requested by AB Astra, there are no
current third-party claims concerning any of the Process Patents.

11.  Liability and Indemnity - Liability and indemnity between the contracting
     -----------------------                                                  
parties are subject to the applicable laws.

SICOR shall indemnify, defend, and hold BOEHRINGER and ALCO harmless, against
any and all liability, damage, loss, cost or expense (including reasonable
attorney's fees) resulting from a third party claim made or suit brought against
BOEHRINGER and/or ALCO respectively to the extent such arises out of a claim of
infringement of any intellectual property rights concerning [CONFIDENTIAL
TREATMENT REQUESTED] and/or the Process Patents. Upon filing of any such claim
or suit BOEHRINGER and/or ALCO shall immediately notify SICOR either directly,
or in the case of BOEHRINGER, through ALCO thereof and shall permit SICOR, at
its cost, to handle and control such claim or suit. BOEHRINGER and/or ALCO shall
have the right to participate in the defence of such claim or suit at its own
expense.

Both BOEHRINGER and SICOR shall each maintain a comprehensive general liability
insurance policy providing sufficient extensive coverage for personal injury,
bodily injury, property damages, or such coverage as is usual and customary in
the pharmaceutical industry to procure in the case of activities to be carried
out by the respective party because of and under this Agreement.

12.  Term - This Agreement shall become effective on the last date of signature
     ----                                                                      
hereunder, and shall continue thereafter for fifteen (15) years.  Thereafter
this Agreement shall be automatically renewed for successive one year periods
unless either party hereto gives written notice to the other party at the
address hereinabove of its intentions not to extend the

                                      8/11
<PAGE>
 
term, said notice to be given at least three (3) years prior to expiry of the
then current term.

13.  Termination for Cause - BOEHRINGER shall have the right in its discretion
     ---------------------                                                    
to terminate this Agreement at once by written notice to the other parties in
the event that:

a)  one or both of the other parties should breach or fail to observe or perform
any term or condition of this Agreement, and such breach or default is not cured
and remedied in full within (90) days after written notice thereof is given to
the party or parties at fault.

b)  one of the other party or parties by voluntary or involuntary action go(es)
into liquidation or receivership; or dissolve(s) or file(s) a petition for
bankruptcy or reorganization or for suspension of payments or is (are)
adjudicated as bankrupt, become(s) insolvent or assign(s) or make(s) any
composition of its (their) assets for the benefit of creditors;

c)  ownership of or control over one or both of the other parties is transferred
to others than those presently holding ownership of such party or parties.

d)  if in good faith BOEHRINGER determines that there are reasonable scientific
or commercial reasons to stop development or sale of the Products; provided that
such commercial reasons cannot be solely related to BOEHRINGER's finding lower
prices available for [CONFIDENTIAL TREATMENT REQUESTED] of equivalent quality.

Neither ALCO nor SICOR alone shall have the right to terminate this Agreement.
Notwithstanding the foregoing, ALCO and SICOR together in common accord shall
have the right in their discretion to terminate this Agreement at once by
written notice by both parties to BOEHRINGER in the event that:

a)  BOEHRINGER should breach or fail to observe or perform any term or condition
of this Agreement, and such breach or default is not cured and remedied in full
within (90) days after written notice thereof is given to BOEHRINGER;

b)  BOEHRINGER by voluntary or involuntary action goes into liquidation or
receivership; or dissolves or files a petition for bankruptcy or reorganization
or for suspension of payments or is adjudicated as bankrupt, becomes insolvent
or assigns or makes any composition of its assets for the benefit of creditors;
or

c)  ownership of or control over BOEHRINGER is transferred to others than those
presently holding ownership of BOEHRINGER.

In any of the three aforementioned cases, if only ALCO but not SICOR, or only
SICOR but not ALCO desires to terminate the

                                      9/11
<PAGE>
 
present Agreement, the party so desiring to terminate reserves the right to
those damages directly or indirectly resulting therefrom from the party not
desiring to terminate.

In the event of early termination of this Agreement by BOEHRINGER due to cause

1.1  Upjohn hereby grants to Sicor and its designees exclusive rights to

agency relationship ("rapporto di agenzia").
                      -------------------   

In light of the above, the Parties hereby agree to the following:

1.  APPOINTMENT AS AGENT

1.1  Sicor grants to Alco, which accepts, the appointment as agent without
representation powers and without exclusivity (Non-exclusive Agent) for the
worldwide sale, excluding customers that reside in or carry out their activity
in the countries listed in Appendix 1 (the borders shall be those in existence
                           ----------                                         
at the signing of this Agreement), of the Products listed in Appendix 2.
                                                             ---------- 

1.2  Sicor reserves the right to exclude from this appointment the promotion and

                           ----------                                       
whom Sicor has a direct sales relationship and that, in total, do not represent
more than 10% of Sicor's annual sales revenue.  For 1994, said customers are

                                      -1-
<PAGE>
 
listed in Appendix 3.  For subsequent years, Sicor shall notify Alco of the
          ----------                                                       
names of said customers on or before October 30th of each calendar year, for the
following year.

1.3  Alco, with reference to the Products listed in Appendix 2, shall be the
                                                    ----------              
exclusive agent with reference to customers located in or that carry out their
principle activity in the following countries: Japan, Korea, Taiwan (the borders
shall be those in existence at the signing of this Agreement).

1.4  Excluding the countries set forth in Article 1.3, for the purposes of this
Agreement (not applicable to the territories set forth in Appendix 1 and with
                                                          ----------         
respect to the customers set forth in Article 1.2), Sicor may promote the sale
of the Products directly or by means of third parties, notwithstanding Article
2.3.

2.  RIGHTS OF ALCO

2.1  On the sales made on behalf of Sicor, Alco (whether as Exclusive Agent
pursuant to Article 1.3 or Non-exclusive Agent pursuant to Article 1.1.) shall
have the right to a commission of 5% on the annual sales revenue for properly
executed transactions or part thereof in the event the transaction has only been
partially executed.

     No commission shall be owed to Alco in the event the sales are effectuated
at a price lower than that indicated on the Sicor-Alco price agreement in effect
at the time of sale.

     Moreover, no commission shall be owed to Alco for any sales by Sicor to
customers set forth in Article 1.2.

2.2  Alco, upon the simple written request of Sicor, shall be subject to a "star
                                                                            ----
del credere" and thus shall respond to Sicor with the proper execution of the
- -----------                                                                  
matter.  In such case, Alco shall have the right to a higher commission equal to
1% of the annual sales revenue.

2.3  On sales made by other agents on behalf of Sicor pursuant to Article 1.4 or
on sales made directly by Sicor, Alco, notwithstanding Article 1.2, shall have
the right to a commission equal to the positive difference, if any, between any
commissions owed by Sicor to other agents or intermediaries and 5% of annual
sales revenue for the duly executed transactions or part thereof in the event
the transaction has only been partially executed.

Thus for example, if for a given transaction a commission of 3% is owed to a
third party agent, Sicor shall owe a commission of 2% to Alco.  However, if a
commission of 5% is owed to a third party agent, Sicor shall owe no commission
to Alco.

2.4  No commission shall be owed to Alco for sales made directly by Alco in its
capacity as a sales agent.

                                      -2-

                                                                    ------------


                                   Agreement

Between

Sicor S.p.A., having its registered office at Via Senato no. 19, Milan, Italy,
C.F. and P.I. IT06827530152, hereinafter called SICOR,

                                                        Party of the first part,

and

Alco Chemicals Ltd Swiss France, having its registered office at Via S.
Salvatore, 7, Lugano, [Switzerland], hereinafter called ALCO,

                                                       Party of the second part,

                                    Recital

Whereas in effect there exists between the Parties an agency contract
(hereinafter called "the Contract"), executed on 1/1/94 and subsequently amended
as regards the extent of its provisions by exchange of letters dated 1/2/96 and
1/15/96; and

Whereas several other sales license agreements have been stipulated between the
Parties, for the Cyproterone and Ifosfamide products among others;

Now therefor the Parties stipulate and covenant the following, to wit:

     1.   The Parties reciprocally acknowledge that the reduction of the
          provisions (to 3.5%) mentioned in the exchange of letters dated 1/2/96
          and 1/15/96 referred also to the provision of Article 2.1 of the
          Contract and that the missing mention of such provision under
          paragraph (1) of the cited letter resulted merely from a material
          error.

                                      -1-
<PAGE>
 
     2.   The Parties acknowledge to one another that:
        
          (i)  by mutual agreement of the Parties, the sales licensing agreement
               relating to the Ifosfamide product has not in fact ever been
               implemented by the Parties;
          (ii) by mutual agreement of the Parties, the sales licensing agreement
               relating to the Cyproterone product has not in fact been
               implemented by the Parties since 1/1/1995;

In consequence, the Parties mutually agree, insofar as what might occur in
future, to retroactively terminate such agreements as of the dates indicated
below:

          (i)  with respect to the Ifosfamide product, from the date of signing
               same;
       
          (ii) with respect to the Cyproterone product, from 1/1/1995;
               and reciprocally state to one another that, with respect to these
               agreements, they have no claim whatsoever to anything and, to the
               extent of what might occur in future, waive all claims that might
               possibly derive from the terms and stipulations so terminated,
               including, but not limited to, the provisions regarding the
               conditions for giving notice with a view to termination of the
               contracts.

                                      -2-
<PAGE>
 
     3.   The Parties covenant that, from 1/1/97, the provisions referred to in
          articles 2.1 and 2.3 of the Contract shall be equal to 4%.

     4.   The rights and obligations accruing from the present Agreement are
          personal to the Parties and non transferable without prior written
          agreement from the other Party. Neither Party may transfer or assign
          to any third party any part or all of the rights and obligations
          mentioned in this Agreement, except that ALCO shall have the option to
          discount to financial institutions drafts which have matured according
          to the provisions [of this Agreement].

     5.   The rights of the Parties provided for in this Agreement shall not in
          any way be interpreted as waived or limited in the event of tolerance
          by one Party of a failure by the other Party to perform hereunder and
          no waiver by one Party of its rights subsequent to a failure by the
          other Party to fulfil its obligations may be interpreted as a waiver
          with respect to subsequent and repeated failures to perform.

     6.   Any change, amendment or termination of this Agreement or a single
          provision of this Agreement must be in writing.

     7.   Whenever a provision of this Agreement shall become invalid or
          ineffective, such provision shall be declared null and void but all
          the other provisions shall remain valid and enforceable, except the
          obligation of the Parties to negotiate in good faith a substitute
          provision to that declared invalid or ineffective which might satisfy
          the legitimate interests of both Parties.

                                      -3-

     8.   The law applicable to this Agreement shall be Italian law.

          Any dispute between the Parties which might arise from the
          interpretation, implementation or termination of this Agreement shall
          be referred to the decision of a three-person arbitration panel
          appointed to proceed and decide according to the Italian Code of Civil
          Procedure.

          The international arbitration procedure so established, in conformity
          with sections 812 et seq. of the Code of Civil Procedure shall be the
          regular procedure by right pursuant to the provisions of sections 816
          through 831 of the Code of Civil Procedure.

          The arbitration shall take place in Milan.

Jose Antonio Escandon Septien declares:

  1.  That his principal, the PROVIDER, is a corporation organized and existing

      material and human resources for rendering consulting services in the
      following areas: Business strategy, government relations, financial,
      accounting and business management, internal auditing, legal affairs,

  5.  That the authority required for making the within contract on behalf of
      his principal has not been revoked as of the present date.

      declarations.

                                      -1-
<PAGE>
 
In view of the foregoing, the parties hereto stipulate the following

                                    CLAUSES:
                                    ------- 


FIRST.- The PROVIDER undertakes to furnish the CLIENT with the services required
by the latter in those areas set forth in declaration fourth above, as well as
in any other service area that may be connected therewith, whenever requested by
the CLIENT within the context of the within contract.

SECOND.- The PROVIDER agrees, if so requested by the CLIENT, to provide and
render the services referred to in the preceding clause directly to the CLIENT
at its domicile located at Avenida San Rafael No. 35, Parque Industrial Lerma,
Lerma de Villada, CP 52000, Estado Mexico, or else at any such premises that may
be advised or requested by the CLIENT, even if such premises are owned by third-
parties, provided that such services are of the same kind as constitute the
subject matter of the present contract.

THIRD.- The services which the PROVIDER will render the CLIENT shall be
furnished with the CLIENT's own human and material resources, but in no way or
manner shall the said services carry with them a delegation of decision-making
or management powers, nor of any powers inherent in the operation of the
company, which powers shall in all cases remain vested in and with the CLIENT.

FOURTH.- As consideration for the services to be provided in accordance with
Clause First by the PROVIDER to the CLIENT, the latter shall pay the former a
fee that will come to the sum of One Hundred Seven New Mexican Pesos (NM$107.00)
per hour for the rendering of the said services.  This fee shall be
reviewed/revised semi-annually, and what is agreed to by the parties shall be
appended hereto as a rider.

FIFTH.- For purposes of determining the amount of the consideration under the
terms of Clause Fourth above, the PROVIDER undertakes to maintain an accounting
system that will reasonably allow for determining the amount of direct and
indirect operating costs incurred for the providing of the services.

The direct and indirect operating costs referred to in this clause do not
include payment of taxes, notarial fees, travel, meals or other costs of a
similar nature that might be incurred on behalf of the CLIENT, and for such
reason, these types of costs shall be absorbed directly by the CLIENT,
notwithstanding those incurred by the PROVIDER's staff.   Said staff shall
request that the appropriate expense voucher be marked or made out in the name
of the CLIENT, to whom the respective expense report will have to be submitted
in accordance with the policies and procedures established by the CLIENT, who
will have to authorize said report, with a copy to the PROVIDER.  Likewise, the
direct and indirect costs referred to in this clause do not include financing
interest or costs that are incurred or may be incurred by the PROVIDER, but on
the other hand, those costs or expenses which may have been incurred as of the
end of a fiscal or business year will be included, even if they have not been
paid in full.

                                      -2-
<PAGE>
 
SIXTH.- The sum which as consideration the CLIENT is obligated to pay the
PROVIDER shall be determined by the latter depending on the amount of the
operating costs.  The CLIENT shall deliver a monthly advance on account of the
services, taking the average of the last two months as a basis; such advance
shall be delivered within the first ten (10) days of the month.

SEVENTH.- The PROVIDER undertakes to put forth its best efforts to render the
services efficiently, continuously, responsibly and diligently.

EIGHTH.- The PROVIDER agrees to maintain confidential any and all documents and
information received from the CLIENT at the latter's business domicile.

NINTH.- During the life of this contract, the PROVIDER shall have full
responsibility for the efficient rendering and execution per se of the subject
services, and therefore the PROVIDER shall be solely responsible and answerable
to the CLIENT for the rendering of the services described in Clause First, it
being authorized for such purpose to send such persons as it may designate to
the CLIENT's facilities, or to such places where the activities are being
conducted, or to any other place agreed to by the parties, for the purpose of
having the services rendered properly and adequately.

TENTH.- It is duly understood that the PROVIDER shall pay all contributions,
taxes and fees which under law may be assessed on its business, and that the
CLIENT is not nor will be responsible for any acts that may be committed by the
PROVIDER or by its employees during the rendering of the services hereunder.  It
is likewise expressly understood that the PROVIDER has the status of employer
insofar as concerns the personnel under its control and direction, and through
whom the services will be rendered, and that it has its own sufficient means for
meeting all corresponding labor-related obligations, and that this contract does
not grant any status of representative or intermediary to the CLIENT.

ELEVENTH.- Both parties agree that each shall be responsible for any labor or
labor-related obligations deriving from the relationship existing with their
respective employees, and in no case and for no reason may the employees of any
of the parties consider the other as an employer.  For such purpose, the
PROVIDER undertakes to enter into written employment agreements with its own
employee-workers, which agreements clearly state that the PROVIDER is the only
employer which the worker recognizes, and agrees that no contractual
relationship exists between he or she (the worker) and the CLIENT, who shall be
considered totally disconnected from any such labor agreement made.

TWELFTH.- The within contract shall have a term of one (1) year from the date on
which it is made, but may be automatically renewed for similar one-year periods
with the understanding that either party may terminate it by giving written
notice to the other party thirty (30) days in advance or within any other party
agreed to by the parties, provided that no debt exists between the parties in
connection herewith.

In respect to everything stipulated herein, the parties expressly submit to the
laws of the Federal District, and in respect to interpretation and compliance,
the parties accept the

                                      -3-
<PAGE>
 
jurisdiction of the courts and tribunals of Mexico City, D.F., waiving any other
jurisdiction which they currently have or might have in the future by reason of
their domicile or by reason of anything else.

IN WITNESS WHEREOF, the parties through their designated legal representatives
affix their signatures hereto in triplicate, in Mexico City, Federal District,
with effectiveness commencing January 2, 1995.

Dear Don:

Thanks for flying to New York to meet with Carlo and me to discuss your becoming

a major worldwide specialty pharmaceutical company.

We have agreed on the following terms relating to your acceptance of this
position:

     1.  You will serve as a member of the Board of Directors and as non-
         executive Chairman of the Board for a period of two years. You will not
         be either an officer or an employee of Gensia Sicor.

     2.  You will advise and consult with the Company on strategic planning as
         requested.

     3.  You will help the Company with positioning and with contacts in the
         financial community.

     4.  You will assist Carlo Salvi, a principal shareholder and a director of
         the Company,  with introductions to the investment community.

     5.  You will be available to the Company for other assignments, as
         appropriate.

We have also agreed on the following terms relating to your compensation:

     1.  A fee of $200,000 per year, paid monthly. You will serve at the
         pleasure of the Board, and upon the cessation of your services, no
         further fees will be payable provided that you will receive a minimum
         of $200,000.

     2.  Reasonable expenses for your office related to your activities as non-
         executive Chairman.

     3.  Options on 200,000 shares of Gensia Sicor common stock, immediately
         vested, at the average closing market price of Gensia common stock for

     4.  The Company will grant options for Gensia Sicor common stock at the
         average closing market price for the ten (10) trading days ending on
         the day immediately prior to our announcement of your role with Gensia
         Sicor for up to 300,000 additional shares which will be exercisable, in
         increments of 100,000 shares per increase in market capitalization
         (other than increases due to corporate reorganizations, combinations or
         similar transactions) for the Company of $100 million for increases in
         market capitalization over $700 million.

     5.  If during the three-year period from the date of you becoming non-
         executive Chairman, the market capitalization of the Company reaches $1
         billion, you will receive a bonus of $1 million in the form of an
         annuity payable over 10 years, which amount may be paid by the Company
         in stock or cash.

     6.  The Company will pay reasonable expenses related to your activities
         with the Company.

The terms contained in this letter are conditional upon shareholder approval of
the Gensia Sicor combination on February 26, 1997 and on the closing of the
Gensia Sicor transaction on or about February 28, 1997.  Certain aspects of the
stock options to be granted to you will be subject to Board and shareholder
approval, which we shall endeavor to obtain at the next annual meeting of
shareholders.  Please review and if the terms in this letter reflect our
discussions in New York, please sign a copy of this letter and return it to me
and keep a copy for your records.  If this meets with your approval, we will
prepare a formal Consulting Agreement that sets forth these and other
appropriate terms.  Carlo and I look forward to working with you very much to
make Gensia Sicor successful.

Sincerely,
