                          SANGSTAT MEDICAL CORPORATION

              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS



Basis of Presentation

The consolidated financial statements include the accounts of SangStat Medical
Corporation and its wholly owned subsidiaries. Intercompany accounts and
transactions have been eliminated.

While the quarterly financial information in this filing is unaudited, the
financial statements presented reflect all adjustments (consisting only of
normal recurring adjustments) which the Company considers necessary for a fair
presentation of the results of operations for the interim periods covered and of
the financial condition of the Company at the dates of the interim balance
sheets. These results for interim periods are not necessarily indicative of the
results for the entire year. The information included in this report should be
read in conjunction with the Company's audited financial statements and notes
thereto included in the Company's 1996 Annual Report to Shareholders.


Per Share Information

Net loss per common share is computed using the weighted average number of
common shares outstanding during the period. Common equivalent shares, including
stock options granted by the Company, have been excluded in the calculation of
common shares outstanding since they would serve to reduce the net loss per
share.


Inventories

Inventories, valued at the lower of cost (first-in, first-out) or market consist
of:

Public Offering

In April 1997, the Company completed a public offering, including the
underwriters' over-allotment, of a total of 2.73 million shares at $30.00 per
share with net proceeds of $76,635,000.

Recently Issued Accounting Standards

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, "Earnings per Share" (SFAS 128). The
Company is required to adopt SFAS 128 in the fourth quarter of 1997. SFAS 128
establishes the accounting standards for computing and presenting earnings per
share. The Company expects that this adoption will not have a material effect on
reported earnings (loss) per share.

In June 1997, the Financial Accounting Standards Board adopted Statements of
Financial Accounting Standards No. 130 "Reporting Comprehensive Income", which
requires that an enterprise report by major components and as a single total,
the change in its net assets during the period from nonowner sources; and No.
131 "Disclosures about Segments of an Enterprise and Related Information" which
establishes annual and interim reporting standards for an enterprise's business
segments and related disclosures about its products, services, geographic areas,
and major customers. Adoption of these statements will not impact the Company's
consolidated financial position, results of operations or cash flows. Both
statements are effective for fiscal years beginning after December 15, 1997,
with earlier application permitted.

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


RESULTS OF OPERATIONS -- THREE AND SIX MONTHS ENDED JUNE 30, 1997 AND 1996

Total revenues. Net product sales in the second quarter of 1997 increased to
$712,000 from $381,000 in the same quarter of 1996. This increase of $331,000 or
87% reflects an increase of 195% in sales of monitoring products, including
PRA-STAT(R) and CROSS-STAT(R), sales of THE TRANSPLANT PHARMACY (which began in
third quarter 1996), partially offset by a decrease of 30% in revenues from
compassionate use of THYMOGLOBULIN(R).  Net product sales in the first half of
1997 increased to $1,402,000 from $1,093,000 in the first half of 1996. This in
crease of $309,000 or 28% similarly reflects an increase of 49% in sales of
monitoring products, including PRA-STAT and CROSS-STAT, continuing sales of THE
TRANSPLANT PHARMACY, partially offset by a 33% decline in revenues from
compassionate use of  THYMOGLOBULIN. The changes in sales of THYMOGLOBULIN in
Canada under that  country's Emergency Drug Release (EDR) Program reflect
variable need for compassionate use.

Cost of sales and manufacturing. Cost of sales and manufacturing expenses
increased to $791,000 in the second quarter of 1997 from $594,000 in the
corresponding quarter of 1996. This increase of $197,000 or 33% was
substantially due to additional costs associated with increased sales of
monitoring products and the commencement of THE TRANSPLANT PHARMACY sales and
partially offset by a 21% decline in costs of sales in Canada. Cost of sales and
manufacturing expenses increased to $1,493,000 in the first half of 1997 from
$1,289,000 in the first half of 1996. This increase of $204,000 or 16% reflects
a 4% increase in costs of monitoring products, costs of sales for THE TRANSPLANT
PHARMACY and a 26% decrease in costs of sales in Canada. The Company's
monitoring products business does not currently generate a profit, because the
Company has not achieved a scale of production which allows it to cover fixed
manufacturing costs.

Research and development. Research and development expenses increased to
$4,286,000 in the second quarter of 1997 from $1,826,000 in the same period in
1996. This increase of $2,460,000 or 135% primarily reflects the initiation of
several clinical trials in transplant patients for CYCLOSPORINE and
THYMOGLOBULIN and continuing product development of AZATHIOPRINE, ALLOTRAP(R)
peptides and XENOJECT(TM). In April 1997 the Company announced its expansion of
clinical trials with CYCLOSPORINE and THYMOGLOBULIN and has since received 
Institutional Review Board (IRB) approval for several clinical trials
for converting renal, heart and liver transplant recipients currently on
Novartis' Neoral to SangStat's CYCLOSPORINE. These trials are designed to
provide valuable information on the pharmacokinetics, safety and efficacy of
conversion from Neoral to SangStat's CYCLOSPORINE. In April, a key goal in
preparing for potential commercialization of SangStat's finished CYCLOSPORINE
drug product was achieved. SangStat and Gensia Sicor announced a definitive
supply agreement for commercial scale production of cyclosporine bulk material
for SangStat's proprietary CYCLOSPORINE drug candidate for the anticipated
worldwide market. On July 2, 1997, the FDA approved Gensia Sicor's application
for the manufacture of bulk cyclosporine drug substance. This approval
represents an important step forward in the regulatory process for approval of
SangStat's finished CYCLOSPORINE drug product. Research and development expenses
increased to $7,669,000 in the first half of 1997 from $4,055,000 in the first
half of 1996. This increase of $3,614,000 or 89% reflects, in addition to the
key events described above for the second quarter 1997, support of an on going
trial utilizing THYMOGLOBULIN for induction therapy to prevent acute rejection
in kidney transplant recipients. This is not a registration study but may
provide useful data to help assess the potential of this indication of
THYMOGLOBULIN. The FDA accepted the Company's applications for market clearance
of its 


                                      -8-


<PAGE>   9


proprietary CYCLOSPORINE for prevention of organ transplant rejection, and
THYMOGLOBULIN, for treatment of rejection, in first quarter 1997 and both drugs
are now under active review by the FDA. The Company announced in April 1997 that
it is planning to expand its clinical trial programs and in accordance with
these and the Company's marketing plans, the Company expects research and
development expenses to increase in the next few quarters.

Selling, general and administrative. Selling, general and administrative
expenses increased to $2,646,000 in the second quarter of 1997 from $1,338,000
in the same quarter of the previous year. This increase of $1,308,000 or 98%
reflects in part that the Company established its own sales staffs in the United
States and Europe and expanded its sales and marketing group in Canada in third
quarter 1996 in connection with the Company's reacquisition of marketing rights
to PRA-STAT and CROSS-STAT from Baxter Healthcare Corporation in July 1996.
Also, in May 1997, R. J. Tesi, M.D., joined the Company as Senior Vice President
of Marketing, in accordance with the Company's announcement in April 1997 of its
plans to expand its sales and marketing staff to further its near term
commercialization strategies. As a result of these events, sales and
marketing expenses for monitoring and therapeutic products increased by $608,000
from the second quarter of 1996 to the same quarter in 1997. Selling, general
and administrative expenses further increased by $700,000 in the second quarter
of 1997 as compared to the second quarter of 1996 as the result of the continued
expansion of the pilot program for THE TRANSPLANT PHARMACY, as well as expanded
patent and other general and administrative activities. Selling, general and
administrative expenses increased to $4,472,000 in the first half of 1997 from
$2,341,000 in the first half of 1996. This increase of $2,131,000 or 91% is
attributable to an increase of $1,090,000 in sales and marketing for monitoring
and therapeutic products and an increase of $1,041,000 in general administrative
expenses, including THE TRANSPLANT PHARMACY. The Company is currently building
its sales and marketing team in anticipation of potential approvals for market
clearance for THYMOGLOBULIN and CYCLOSPORINE. In the next several quarters, the
Company expects to hire its acute care sales force so that, in the event of
market clearances, the Company will be ready to launch its products.
Accordingly, the Company expects selling, general and administrative expenses to
increase in the next several quarters.

Other income and expenses. Interest income increased by $874,000 or 119% to
$1,609,000 in the first quarter of 1997 from $735,000 in the second quarter 1996
and also increased by $1,393,000 or 149% to $2,331,000 in the first half of 1997
from $938,000 in the first half of 1996. These increases are due to the increase
in the average cash balance available for investment as a result of the
Company's sale of equity securities in a public offering in March 1997 and the
overallotment completed in April 1997. Interest and other expense for capital
lease obligations and long term notes increased by $9,000 or 13% to $76,000 in
the first half of 1997 from $67,000 in the first half of 1996.

Net loss. The Company's net loss was $5,444,000 or $0.34 per share in the second
quarter of 1997, compared with a net loss of $2,678,000 or $0.20 per share in
the second quarter of 1996. For the first half of 1997, the Company's net loss
was $9,977,000 or $0.67 per share compared with a net loss of $5,721,000 or
$0.49 per share in the first half of 1996.


LIQUIDITY AND CAPITAL RESOURCES

During the first six months of 1997 and 1996, the net cash used in operating
activities was approximately $9,379,000 and $6,106,000, respectively. The
increase in net cash used in operating activities in these periods is due
substantially to the increased amount of net loss incurred in each of these
periods. As of June 30, 1997, the Company had cash, cash equivalents and
short-term investments of $107,668,000 and total assets of $113,007,000.


                                      -9-


<PAGE>   10


Net cash provided by financing activities totaled $76,344,000 and $44,830,000
for the six months ended June 30, 1997 and 1996, respectively. Such amounts were
substantially comprised of proceeds received from the sale of Common Stock in
the Company's public offerings in March 1997 and March 1996, respectively,
offset in part by net repayments of notes payable and capital lease obligations.

Net cash used in investing activities totaled $12,548,000 and $19,294,000 in the
six months ended June 30, 1997 and 1996, respectively, and resulted
substantially from the Company's net purchases of short-term investments.

The Company expects to incur significant costs related to, among other things,
continued clinical and preclinical testing, regulatory approval activities and
research and development programs in the future and the build-up of sales 
staffs in the United States and Europe. If and when the Company receives
FDA approval of its therapeutic drug candidates, the Company expects to have
additional working capital requirements for expansion of sales, increased
inventory levels and payment of certain license obligations. If the Company
receives FDA approval for THYMOGLOBULIN, it would be obligated to make a final
milestone payment under a related license agreement totaling $1.5 million. The
Company believes that its existing capital resources, together with product
sales and interest income will be sufficient to meet the Company's operating and
capital requirements through at least 1998. Although the Company has no current
contractual obligations relating to capital expenditures, it anticipates that
capital expenditures, primarily for its United States operations, will aggregate
approximately $1 million during 1997. The Company's future capital requirements
will depend on many factors, including its research and development programs,
the scope and results of clinical trials, the time and costs involved in
obtaining regulatory approvals, the costs involved in obtaining and enforcing
patents or any litigation by third parties regarding intellectual property, the
status of competitive products, the establishment of sales and marketing
capacity or third-party manufacturing arrangements, the establishment of
collaborative relationships with other parties, and the costs of manufacturing
scale-up and working capital requirements for inventory and financing of
accounts receivable. If adequate funds are not available, the Company may be
required to delay, scale back or eliminate one or more of its development
programs or obtain funds through arrangements with collaborative partners or
others that may require the Company to relinquish rights to certain
technologies, product candidates or products that the Company would not
otherwise relinquish.

This document contains forward-looking statements that involve risks and
uncertainties. Forward-looking statements reflect SangStat's current views with
respect to future events. Actual results may vary materially and adversely from
those anticipated, believed, estimated, or otherwise indicated. Important
factors common to the FDA drug review and approval process could cause actual
results to differ materially with regard to the approvability of SangStat's
THYMOGLOBULIN or CYCLOSPORINE. These factors include, without limitation: (1)
that data obtained from clinical trials are subject to varying interpretations,
and there can be no assurance that the FDA (or an FDA panel of experts) will
agree with SangStat's assessment of clinical trial results; (2) that there can
be no assurance that the agency will not issue new guidelines, guidance
documents, policies, or regulations or otherwise have new, different or
previously unknown requirements that may materially affect the approvability of
either product; and (3) that there can be no assurance of FDA approval of either
product. Other factors that could cause actual results to differ materially
include, without limitation, uncertainty related to the competition
manufacturing of commercial quantities of product on commercially favorable
terms, market acceptance, competition and potential litigation. For a discussion
of other factors that might result in different outcomes, see SangStat's 1996
Annual Report, in particular "Risks Associated With CYCLOSPORINE" set forth
therein, and the Company's filings on Form 10-K and 10-Q with the Securities and
Exchange Commission.

RECENTLY ISSUED ACCOUNTING STANDARDS

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128, "Earnings per Share" (SFAS 128). The
Company is required to adopt SFAS 128 in the fourth quarter of 1997. SFAS 128
establishes the accounting standards for computing and presenting earnings per
share. The Company expects that this adoption will not have a material effect on
reported earnings (loss) per share.

In June 1997, the Financial Accounting Standards Board adopted Statements of
Financial Accounting Standards No. 130 "Reporting Comprehensive Income", which
requires that an enterprise report by major components and as a single total,
the change in its net assets during the period from nonowner sources; and No.
131 "Disclosures about Segments of an Enterprise and Related Information" which
establishes annual and interim reporting standards for an enterprise's business
segments and related disclosures about its products, services, geographic areas,
and major customers. Adoption of these statements will not impact the Company's
consolidated financial position, results of operations or cash flows. Both
statements are effective for fiscal years beginning after December 15, 1997,
with earlier application permitted.

12,614,589; 3,340 and 2,865, respectively. The percent of shares voted in favor

In that a plurality of shares voted for each proposal is necessary for
stockholder approval, all the proposals above were approved by the stockholders
at the Company's Annual Meeting of Stockholders.

addition, at the time of delivery of each forecast, PURCHASER shall place a firm
order in writing for Product to be delivered to it during the * * * after
receipt of such order by GENSIA SICOR ("Firm Order").

               4.1.1 A Firm Order may not be canceled, and, following
performance by GENSIA SICOR (for itself and through SICOR, as appropriate) of
its obligations hereunder with respect to such order, PURCHASER shall be
obligated to pay the price for said order as provided in Article 5 hereof. The
total amount of each Product ordered by PURCHASER for delivery in any * * * for
which an order is required may not be less than * * * percent ( * * * %) of
PURCHASER's * * *. In addition, GENSIA SICOR's supply obligation will not extend
to more than * * * percent ( * * * %) of PURCHASER's * * * of its * * *. If a
PURCHASER Product requirement for any quarter exceeds * * * % of PURCHASER's * *

if any, that GENSIA SICOR is willing to supply consistent with its other
obligations and PURCHASER will adjust its order accordingly.

estimated quantities in each forecast and any Firm Order then outstanding and to
consult on matters relating to the scheduling of manufacture, import and
delivery of the Product but without prejudice and subject to the obligations of
the parties set forth in this Agreement.

foregoing, the parties acknowledge that those Firm Orders set forth in Exhibit 7
with a scheduled delivery date after * * * are conditioned upon earlier receipt
of AADA approval by GENSIA SICOR from the FDA to manufacture Product at its * *
* facility.

                                 CONFIDENTIALITY

               9.1 Except as otherwise provided herein, during the term of this
Agreement and for a period of * * * years following expiration or termination of
this Agreement, each party shall maintain in confidence all confidential or
proprietary information and materials disclosed or provided by the other party
hereto or the other party's Affiliate, which such party knows or has reason to
know are or contain trade secrets or other proprietary or confidential
information relating to the business or properties of the other party, or the
business plans of the other party hereto prior to the date hereof, and shall not
use such trade secrets or proprietary or confidential information for any
purpose, including, without limitation, for the purpose of developing products
except as permitted by this Agreement or disclose the same to anyone other than
those of its Affiliates, employees, consultants, agents or subcontractors as are
necessary in connection with such party's activities as contemplated in this
Agreement. Each party shall obtain a written agreement from any such employees,
consultants, agents and subcontractors, prior to disclosure, to hold in
confidence and not make use of such trade secrets or proprietary or confidential
information for any purpose other than those permitted by this Agreement.

               Notwithstanding the foregoing sentence, with respect to employees
or consultants of a party or such party's Affiliates who have signed a
confidentiality agreement in favor of such party or Affiliate as employer, if
such confidentiality agreement binds the employee or consultant to protect
proprietary information disclosed hereunder to the same extent (or greater) as
required by this Article, then it shall be sufficient for the employing party to
(i) notify such employees or consultants of the fact that information disclosed
hereunder is governed by such confidentiality agreements and (ii) identify to
such employees the information which is so governed. Each party shall be
responsible for ensuring compliance with these obligations by such party's
Affiliates, employees, consultants, agents and subcontractors. Each party shall
use a similar effort to that which it uses to protect its own most valuable
trade secrets or proprietary information to ensure that its Affiliates,
employees, consultants, agents and subcontractors do not disclose or make any
unauthorized use of trade secrets or proprietary information of the other party
hereto. Each party shall notify the other promptly upon discovery of any
unauthorized use or disclosure of the other's trade secrets or proprietary
information. Each party agrees that upon termination of this Agreement, each
party shall return and/or destroy (and certify such destruction to the other
party) all confidential and proprietary information of the other to such other
party, except as may be required by law or regulation and except that each party
may retain one (1) copy for archival purposes and resolution of disputes.

               9.2 The obligation of confidentiality and non-use contained in
this Agreement shall not apply to the extent that (a) the party who has received
information (the "Recipient") is required to disclose information by order or
regulation of a governmental agency or a court of competent jurisdiction or (b)
the Recipient can demonstrate that (i) the disclosed information was at the time
of such disclosure by the Recipient already in the public domain or later
entered the public domain other than as a result of actions of the

hereof; (ii) the disclosed information was rightfully known by the Recipient or
its Affiliates (as shown by its written records) prior to the date of disclosure
to the Recipient in connection with the negotiation, execution or performance of
this Agreement; (iii) the disclosed information was received by the Recipient or
its Affiliates from a source unrelated to any party to this Agreement and not
under a duty of confidentiality to the other party; or (iv) the information can
be shown to have been independently developed by the Recipient, its Affiliates,
employees, agents or subcontractors, without the aid, application or use of any
disclosed information hereunder, or (c) disclosure is made to the appropriate
Regulatory Authorities (including, but not limited to, the FDA) as part of such
Regulatory Authorities' product license review or approval process, or (d)
disclosure is made to Affiliates, employees, consultants, agents or
subcontractors or purchasers in connection with the transactions contemplated by
this Agreement, provided such disclosures are made subject to restrictions
identical in substance to those contained in Section 9.1 above, or with respect
to information provided to purchasers of Product hereunder, information that is
necessary (in the reasonable discretion of GENSIA SICOR) for use of the Product,
provided that in each instance Recipient takes advantage of any available
protective provisions regarding such disclosures of confidential information. In
addition, each of the parties hereto agrees to keep confidential the existence
of this Agreement, unless such existence otherwise becomes known pursuant to
this paragraph, and except to the extent that disclosure is required by law or,
in the case of PURCHASER, to actual or potential investors of PURCHASER, or, in
the case of GENSIA SICOR, to the second source referred to in Section 3.1 above.

               9.3 From the Effective Date, PURCHASER shall be entitled to
receive from GENSIA SICOR (and SICOR, and GENSIA SICOR shall cause SICOR to
provide) all confidential and proprietary information necessary in PURCHASER's
reasonable judgment for PURCHASER to comply with its obligations set forth
herein and to determine GENSIA SICOR's (and SICOR's) ability to comply with its
obligations set forth herein and the accuracy of GENSIA SICOR's (and SICOR's)
prior representations regarding Product.

               9.4 The parties acknowledge and agree that all information,
technology, materials, know how, regulatory filings and permissions (except
where prohibited by law or regulation) developed or prepared by or on behalf of
PURCHASER in connection with this Agreement shall be and remain the confidential
and proprietary information of PURCHASER.

throughout the duration of this Agreement it will notify the other party (and
GENSIA SICOR shall cause SICOR to do the same) (i) immediately with respect to
any information concerning any serious or unexpected complaint anywhere
involving the possible failure of the Product to meet any specifications, and
any serious or unexpected side effect, injury, toxicity or sensitivity reaction
or any unexpected incidents and the severity thereof associated with the
distribution of the Product, whether or not determined to be attributable to the
Product, and (ii) within a reasonable period of time that is at least consistent
with applicable regulatory guidelines with respect to any other complaints.

               11.2 Subject to Section 2.2, PURCHASER and GENSIA SICOR shall
(and GENSIA SICOR shall cause SICOR to) immediately notify the other party (and
GENSIA SICOR shall cause SICOR to do the same) of any information it receives
regarding any threatened or pending action, inspection or communication by or
from a concerned regulatory agency which may affect the safety or efficacy
claims of the Product or the continued marketing of the Product. Upon receipt of
such information, the parties shall consult in an effort to arrive at a mutually
acceptable procedure for taking appropriate action.

               11.3 If at any time or from time to time any regulatory agency
having jurisdiction in the Territory requests either party to recall the Product
or a Cyclosporine Formulation due to a defect in the manufacture, formulation,
processing, packaging or labeling of the Product or a Cyclosporine Formulation
or for any reason whatsoever, the party to whom such request is made shall
immediately notify the other party. The recall shall be carried out by PURCHASER
in as expeditious a manner as reasonably possible.

                            WARRANTY AND LIMITATIONS

               12.1 EXCEPT AS EXPRESSLY PROVIDED HEREIN, GENSIA SICOR MAKES NO
WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING ANY IMPLIED WARRANTS OF
MERCHANTABILITY. Subject to the following provisions of this Article 12, GENSIA
SICOR shall cause SICOR to warrant that all Product at the time title to such
Product passes to the PURCHASER (A) is of good and merchantable quality,
conforms to the Q/C Specifications, and has been manufactured in accordance with
all applicable regulatory requirements (including, without limitation all
current Good Manufacturing Practices), as provided by the Regulatory Authorities
of the Territory and the jurisdiction in which it is manufactured, (B) shall
have, at least, minimum shelf life initially to be * * *, and (C) that Product
performance/potency/efficacy throughout the shelf life period shall be within
the Q/C Specifications so long as Product is properly stored as per

change, deviation from or other modification to the manufacturing process,
facilities or materials reviewed and, where required, approved by the
appropriate Regulatory Authorities, may require additional approval and/or
review from such authority, and that the manufacturing process, facilities and
materials that are the subject of such review and/or approval, constitute a
material part of the Q/C Specifications and other applicable regulatory
requirements covered by this warranty. Except with respect to claims relating to
the performance/potency/efficacy of the Product throughout the shelf-life
specified above, claims that any given shipment of Product does not meet such
Q/C Specifications or otherwise fails the requirements set forth in this Article
12 shall be made by PURCHASER to GENSIA SICOR in writing within * * * after
discovery by PURCHASER that such Q/C Specifications or other requirements have
not been met.

               12.2 If PURCHASER claims that any shipment of Product did not
conform to the warranties set forth in Section 12.1, conform to the Q/C
Specifications or other requirements hereunder, GENSIA SICOR (through SICOR)
shall conduct or have conducted an assay of its retained samples from such
shipment. If GENSIA SICOR agrees with PURCHASER's claim, GENSIA SICOR (through
SICOR) at its option shall either replace such shipment of Product or give
credit for payment if such payment has already been made by PURCHASER for such
shipment including any related reasonable expenses to PURCHASER. If the parties
do not agree on PURCHASER's claim, then the parties shall designate by mutual
agreement a third party laboratory to make such determination from samples
obtained from the batch or other quantity shipped. The decision of the third
party laboratory shall be binding. Should such laboratory confirm PURCHASER's
claim, GENSIA SICOR (through SICOR) may exercise the option described above in
this Section 12.2 should such laboratory find no basis for PURCHASER's claim,
then PURCHASER shall bear the costs of the third party laboratory and reasonable
costs incurred by GENSIA SICOR (through SICOR) for conducting an assay of
retained samples. If PURCHASER identifies Product that it believes does not
conform to the warranty set forth in this Article 12, PURCHASER may withhold
payment to GENSIA SICOR (and SICOR), or in the case of Product supplied
hereunder into the United States, to VINCHEM of any amount due in respect of
such Product and deposit such withheld payment in a * * * certificate of deposit
account with Silicon Valley Bank, until such time as the parties have determined
whether such Product conforms to the warranty described in this Article 11, or
PURCHASER receives replacement Product that conforms to such warranty. In the
event that the subject Product is determined to be conforming, GENSIA SICOR
shall receive all amounts in such certificate of deposit account.

               12.3 Subject to Section 12.5 below, GENSIA SICOR shall (and
GENSIA SICOR shall cause SICOR to) indemnify PURCHASER, and VINCHEM in the case
of Product supplied hereunder into the United States, from and against all or
any actions, proceedings, costs, claims, demands, liabilities and/or third party
expenses (including but not limited to reasonable attorneys' fees and expenses)
arising out of any breach of the warranties made in this Article 12 or the
representations and warranties set forth in Section 2.3.

hereunder into the United States, from and against all or any actions,
proceedings, costs, claims, demands, liabilities and/or third party expenses
(including but not limited to reasonable attorneys' fees and expenses) arising
out of the development, manufacture, use or sale of the Cyclosporine
Formulations by PURCHASER.

               12.5 In the event of any claim being made against a party hereto
("the Indemnified Party") for which the other party (the "Indemnifying Party")
has agreed to indemnify the Indemnified Party pursuant to this Article 12, the
Indemnifying Party shall be promptly notified thereof and may, in its discretion
and at any time, assume and control all negotiations for the settlement of the
same and any litigation (including, but not limited to, the defense of any
claim) that may arise therefrom. The Indemnified Party shall provide such
assistance with respect to any settlement or litigation efforts by the
Indemnifying Party as the Indemnifying Party may reasonably request. Subject to
the other provisions of this Section 12.5, the Indemnifying Party may, at its
sole expense, participate in the defense of any claim hereunder with counsel of
its own choice.

               12.6 IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER FOR
ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL OR INDIRECT DAMAGES ARISING IN ANY WAY
OUT OF THIS AGREEMENT, HOWEVER CAUSED AND ON ANY THEORY OF LIABILITY.

               If any provision of this Agreement should be or become fully or
partly invalid or unenforceable for any reason whatsoever or violate any
applicable law, this Agreement is to be considered divisible as to such
provision and such provision is to be deleted from this Agreement, and the

               1. ALCO (through SICOR) shall manufacture the Product in full
compliance with all applicable cGMPs in each country in which Cyclosporine
Formulations of Product are intended to be sold or are sold. In addition,
PURCHASER will be informed immediately by telephone of any process exceptions
(whether or not authorized in advance by PURCHASER) and all regulatory agency
inspections or notices concerning or affecting any Product tendered hereunder or
the Product manufacturing process following tender of Product to PURCHASER. With
respect to any process exception not authorized in advance to PURCHASER, ALCO
(through SICOR) agrees to diligently and completely investigate and analyze the
cause of such exception and complete such investigation and analysis with
respect to such exception within * * * days of the first reported occurrence of
such exception. In addition, ALCO (through SICOR) agrees to provide PURCHASER
with copies of all reports prepared in connection with each investigation,
notice or process exception.

               2. Attached hereto and incorporated herein are External
Specifications with which the Product tendered hereunder shall comply, except
for the following items: * * * specifications which the parties shall establish
by no later than * * * and with which the Product tendered hereunder shall
comply thereafter. In addition, the parties shall mutually agree on Internal
Specifications by no later than * * *, which shall be based on the manufacturing
experience for the Product through that date; the Internal Specifications
attached hereto shall serve as guidelines that ALCO (through SICOR) shall use
its commercially reasonable efforts to achieve, and which shall serve as a basis
for establishing the Internal Specifications, but which shall not otherwise have
any effect.

               3. Records for each batch of Product tendered hereunder shall be
completed and audited in a manner reasonably satisfactory to PURCHASER, and
according to cGMPs, within * * * business days from the completion date of such
batch. Such batch records shall include * * *. Such batch records shall be
deemed to be confidential information. Promptly following completion of such
audit, ALCO (and SICOR) shall certify in writing to PURCHASER that such records
have been completed and audited with cGMPs.

               4. With each batch of Product ordered hereunder, ALCO (through
SICOR) shall submit to PURCHASER a certificate of analysis in form and content
reasonably acceptable to PURCHASER listing test results and audit confirmation
for each such batch in the manner more particularly described below. All
quantities of Product shipped to PURCHASER shall be properly labelled according
to cGMPs and as reasonably instructed by PURCHASER. With respect to each batch

hereunder, PURCHASER shall perform confirmatory testing and review all records
within * * * days of receipt of such Product at PURCHASER's processing facility
to determine whether or not it complies with the Q/C Specifications. PURCHASER
may reject all Product that fails to meet the Q/C Specifications by giving ALCO
(and/or SICOR) written notice within such * * * day period. If PURCHASER fails
to notify ALCO (and/or SICOR) of any nonconformity within such * * * day period,
PURCHASER shall be deemed to have accepted the Product. No payment for a batch
of a Product shall be due or owing unless PURCHASER has accepted such Product.

               5. If PURCHASER claims that any batch of Product tendered
hereunder fails to meet the Q/C Specifications, and the parties do not otherwise
mutually agree, the parties shall refer to the procedure set forth in Article 11
of the Agreement.

               6. PURCHASER shall have the right, but not the obligation, to
consult with respect to the development of SICOR's quality control procedures
and records pertaining to the Product tendered hereunder.

               7. PURCHASER reserves the right to, from time to time audit and

areas and related departmental and Product documentation.

investigations that are provided to ALCO (and/or SICOR) by Regulatory
Authorities or other purchasers of Product including, all but not limited to,
responses to Regulatory Authorities of notices, inspections, reports or
