PART 1. FINANCIAL INFORMATION

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

The discussion below includes forward-looking statements that involve a number
of risks and uncertainties. A number of factors, both foreseen and unforeseen,
could cause actual results to differ from current expectations of La Jolla
Pharmaceutical Company (the "Company" or "LJP"). Included among these factors
are the uncertainties associated with clinical trials of LJP 394, the Company's
drug candidate for the treatment of lupus, including the possibility that LJP
394 will not prove effective in producing a sustained reduction of dsDNA
antibodies in large patient populations or provide a meaningful clinical
benefit. The Company's other potential drug candidates are at earlier stages of
development and involve comparable risks. Additional risk factors include the
uncertainty of future revenue from product sales or other sources such as
collaborative relationships, the uncertainty of future profitability, the
Company's dependence on patents and other proprietary rights, the Company's
limited manufacturing capabilities and the Company's lack of marketing
experience. Readers are cautioned not to place undue reliance upon
forward-looking statements, which speak only as of the date hereof, and the
Company undertakes no obligation to update forward-looking statements to reflect
events or circumstances occurring after the date hereof. Interested parties are
urged to review the risks detailed from time to time in the Company's annual
reports on Form 10-K and the Company's registration statements on file with the
SEC.

OVERVIEW

Since its inception in May 1989, the Company has devoted substantially all of
its resources to the research and development of technology and potential drugs
to treat antibody-mediated diseases. The Company has never generated any revenue
from product sales and has relied upon private and public investors, equipment
lease financings, a payment from its former collaborative partner, and interest
income on invested cash balances for its working capital. The Company has been
unprofitable since inception and expects to incur substantial and increasing
operating losses for at least the next several years as it increases
expenditures on research and development and allocates significant and
increasing resources to its clinical trials, manufacturing, and marketing
activities. The Company's activities to date are not as broad in depth or scope
as the activities it must undertake in the future, and the Company's historical
operations and the financial information included in this report are not
indicative of its future operating results or financial condition.

In September 1995, the Company entered into a collaborative agreement with Leo
Pharmaceutical Products, Ltd. ("Leo Pharmaceutical") of Denmark pursuant to
which the Company granted to Leo Pharmaceutical the exclusive right to
distribute LJP 394 in Europe and the Middle East. In May 1996, the Company
terminated the collaborative agreement because the Company and Leo
Pharmaceutical could not reach agreement regarding the timing and allocation of
resources with respect to further clinical trials of LJP 394. Under the
termination provisions of the agreement, the Company retained a $3.0 million
payment previously received from Leo Pharmaceutical, and neither the Company nor
Leo Pharmaceutical has any further obligations. As a result of the termination
of the collaborative agreement with Leo Pharmaceutical, the Company will be
required to fund all development costs of LJP 394. The Company intends to pursue
collaborative arrangements with other pharmaceutical companies to assist in its
research programs and the clinical development and commercialization of LJP 394
and its other drug candidates. There can be no assurance that the Company will
be able to negotiate arrangements with any other collaborative partners on
acceptable terms, if at all, or that any such collaborations will be successful.
Failure to establish or maintain collaborative arrangements will require the
Company to fund all of its research and development activities, resulting in
accelerated depletion of the Company's capital,

                                       7
   8
                         LA JOLLA PHARMACEUTICAL COMPANY
                          (A DEVELOPMENT STAGE COMPANY)

and will require the Company to develop its own marketing capabilities for any
drug candidate that may receive regulatory approval. As a result, failure to
establish or maintain collaborative arrangements could have a material adverse
effect on the Company's business, financial condition and results of operations.

The Company expects that losses will fluctuate from quarter to quarter as a
result of differences in the timing of expenses incurred and potential revenues
from collaborative arrangements, if any, and such fluctuations may be
significant. The Company's research and development expenses are expected to
increase significantly in the future as the Company increases its development
efforts. As of September 30, 1996, the Company's accumulated deficit was $47.7
million.

The Company's business is subject to significant risks, including but not
limited to the risks inherent in its research and development efforts, including
clinical trials; uncertainties associated both with obtaining and enforcing its
patents and with the patent rights of others; the lengthy, expensive and
uncertain process of seeking regulatory approvals; uncertainties regarding
government reforms and of product pricing and reimbursement levels;
technological change and competition; manufacturing uncertainties and dependence
on any collaborative partners and other third parties. All of the Company's
product development efforts are based upon unproven technologies and therapeutic
approaches that have not been widely tested or used. To date, the Company's
Tolerance Technology has been used only in the preclinical tests and clinical
trials of LJP 394 conducted by the Company. Application of Tolerance Technology
to antibody-mediated diseases other than lupus is in earlier discovery or
preclinical research stages. LJP 394 and any other potential drug candidates of
the Company will require significant additional research and development and are
subject to significant risks. The mechanism of action utilized by LJP 394 is
unproven in humans, and to date, no therapeutic products have been developed
that target the activity of specific B cells. There can be no assurance that LJP
394 will reliably induce or sustain suppression of disease-causing antibodies,
or that LJP 394 will prove to be safe or effective. Furthermore, clinical trials
of LJP 394 may be viewed as a test of the Company's entire Tolerance Technology
approach. If these clinical trials encounter problems or are otherwise
unsuccessful, the applicability of the Company's Tolerance Technology to other
antibody-mediated diseases will be highly uncertain. Even if the Company's
product candidates appear promising at an early stage of development, they may
not reach the market for numerous reasons. Such reasons include the
possibilities that the products will be ineffective or unsafe during clinical
trials, will fail to receive necessary regulatory approvals, will be difficult
to manufacture on a large scale, will be uneconomical to market or will be
precluded from commercialization by proprietary rights of third parties.

RESULTS OF OPERATIONS

The Company had no revenues in the first nine months of 1996 and had $3.0
million in revenues for the first nine months of 1995, consisting of a one-time
payment received in September 1995 upon the execution of its agreement with Leo
Pharmaceutical. The agreement was subsequently terminated in May 1996 as
described above and will not result in further revenue.

Research and development expenses decreased to $2.7 million for the third
quarter of 1996 from $3.1 million for the same period in 1995. For the nine
months ended September 30, 1996, research and development expenses increased to
$7.8 from $7.5 million for the same period in 1995. The decrease in research and
development expenses for the third quarter of 1996 compared to the third quarter
of 1995 was primarily due to clinical trial costs and costs associated with
collaboration activities in 1995, partially offset by an increase in
manufacturing scale-up activities for the Company's next clinical trials. The
decrease in research and development costs from the third quarter of 1995 was
not typical and is not expected to recur; research and development expenses are
expected to increase quarter-to-quarter in the future. The increase in research
and development expenses for the nine months ended September 30, 1996 compared
to the same period in 1995, was due primarily to manufacturing scale-up
activities for the

                         LA JOLLA PHARMACEUTICAL COMPANY
                          (A DEVELOPMENT STAGE COMPANY)

Company's next clinical trials of LJP 394, additions to research and development
personnel, expansion of the Company's research and development programs, and
increased facilities expenditures.

General and administrative expenses increased to $631,000 for the third quarter
of 1996 from $410,000 for the same period in 1995. For the nine months ended
September 30, 1996, general and administrative expenses increased to $1.8
million from $1.3 million for the same period in 1995. The increase was
primarily attributable to increased personnel to support increased research and
development and clinical activities, and increased corporate development
expenditures. The Company expects general and administrative expense to increase
at a greater rate in the future, among other reasons, because the Company is
taking on additional space in an adjacent building to accommodate anticipated
increases in manufacturing and research and development activities.

Interest income increased to $274,000 for the third quarter of 1996 from
$264,000 for the same period in 1995. For the nine months ended September 30,
1996, interest income increased to $896,000 from $603,000 for the same period in
1995. The increase in interest income was due to higher investment balances
following receipt of the net proceeds of the Company's public offerings in July
and August 1996, and in June 1995, its sale of stock to a private investor in
October 1995, and the payment from Leo Pharmaceutical in September 1995. For the
third quarter of 1996, interest expense decreased to $42,000 from $72,000 for
the same period in 1995. For the nine months ended September 30, 1996, interest
expense decreased to $150,000 from $237,000 for the same period in 1995. The
decrease was the result of decreases in the Company's capital lease obligations.

LIQUIDITY AND CAPITAL RESOURCES

Since its inception, the Company has financed its operations through private and
public offerings of its securities, capital and operating lease transactions,
the payment from Leo Pharmaceutical, and interest income on its invested cash
balances. As of September 30, 1996, the Company had raised $71.6 million in net
proceeds since inception from sales of equity securities.

At September 30, 1996, the Company had $23.3 million in cash, cash equivalents
and short-term investments, as compared to $23.7 million at December 31, 1995.
The Company's working capital at September 30, 1996 was $22.6 million compared
to $21.9 million at December 31, 1995. The increases in cash, cash equivalents
and short-term investments and in working capital resulted from the net proceeds
of approximately $9.8 million from an underwritten public stock offering in July
and August 1996, partially offset by the continued use of the Company's cash
toward expenses of ongoing research and development and clinical programs, and
related general and administrative expenses. The Company invests its cash in
investment-grade, interest bearing instruments.

As of September 30, 1996, the Company had acquired an aggregate of $4.6 million
in equipment, furniture and fixtures, of which approximately $3.2 million had
been acquired through capital lease obligations. In addition, the Company leases
its office and laboratory facilities as well as certain scientific equipment
under operating leases. The Company anticipates increasing investment in
furniture, fixtures and equipment to enhance its manufacturing capabilities and
build out additional space in its headquarters facility to accommodate expected
increases in research and development and manufacturing activities.

The Company intends to use its financial resources to fund clinical trials,
research and development, manufacturing scale-up, and for working capital and
other general corporate purposes. Anticipated near-term expenses include costs
of additional clinical trials for LJP 394, the production of LJP 394 for
toxicology studies and clinical trials, build out of additional space, and the
expansion of research activities. The Company anticipates that its existing
capital and interest earned thereon will be sufficient to fund the Company's
operations as currently planned for at least the next 15 months. However, the
amounts expended by the Company for various purposes may vary significantly, and
it is possible that the Company's cash requirements will differ materially from
and exceed these forward-looking projections and

   10
                         LA JOLLA PHARMACEUTICAL COMPANY
                          (A DEVELOPMENT STAGE COMPANY)

that the Company will therefore need additional financing sooner than currently
expected. The Company's future capital requirements will depend on many factors,
including continued scientific progress in its research and development
programs, the size and complexity of these programs, the scope and results of
preclinical testing and clinical trials, the time and costs involved in applying
for regulatory approvals, the costs involved in preparing, filing, prosecuting,
maintaining and enforcing patent claims, competing technological and market
developments, the ability of the Company to establish and maintain collaborative
arrangements, and the cost of manufacturing scale-up and effective
commercialization activities and arrangements. The Company expects to incur
substantial and increasing losses each year for at least the next several years
as it expands its current research and development programs and invests
increasing amounts of capital in clinical trials, manufacturing scale-up
activities, establishment of marketing and sales capabilities, and
administration of a more complex organization.

The Company has no current means of generating cash flow from operations, and
LJP 394 will not generate revenues, if at all, until it has been proven safe and
effective, has received regulatory approval, and has been successfully
commercialized, a process that is expected to take at least the next several
years. The Company's other drug candidates are much less developed than LJP 394.
There can be no assurance that the Company's product development efforts with
respect to LJP 394 or any other drug candidate will be successfully completed,
that required regulatory approvals will be obtained, or that any product, if
introduced, will be successfully marketed or achieve commercial acceptance.
Accordingly, the Company must continue to rely upon outside sources of financing
to meet its capital needs for the foreseeable future.

The Company will continue to seek capital through any appropriate means,
including the issuance of its securities and establishment of collaborative
arrangements. However, there can be no assurance that additional financing will
be available on acceptable terms, and the Company's negotiating position in its
capital-raising efforts may worsen as it continues to use its existing
resources. There also can be no assurance that the Company will be able to
negotiate arrangements with any collaborative partners on acceptable terms, if
at all, or that any such collaborations will be successful.
