PART I.           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 the 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

The Company has devoted substantially all of its resources to the 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
sole 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 additional 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 testing,
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 or its ability to operate profitably as a commercial
enterprise when and if it succeeds in bringing any product to market.

The Company entered into its first collaborative agreement with Leo
Pharmaceutical Products, Ltd. ("Leo") of Denmark in September 1995. Under this
Agreement, the Company granted to Leo the exclusive right to distribute LJP 394
in Europe and the Middle East, and Leo made an initial $3 million payment to the
Company and is obligated to make further payments upon attainment of certain
milestones. In addition, Leo is responsible for European clinical studies and is
obligated to share certain non-clinical development costs. Since the
announcement of Phase II clinical trials results, the Company and Leo have been
evaluating their respective goals and discussing the allocation of resources and
timing associated with future clinical trials of LJP 394. Commencement of
further studies and related expenditures and payments are pending completion of
these discussions. Both Leo and the Company have the right to terminate their
collaborative arrangement for any reason, and there can be no assurance that 
the Company's relationship with Leo will continue.

                          (A DEVELOPMENT STAGE COMPANY)

In addition, the Company has been conducting discussions with other
pharmaceutical companies that could lead to collaborative relationships in
various geographic markets for the Company's potential drug candidates,
including LJP 394. However, there can be no assurance that the Company will be
able to negotiate future collaborative arrangements on acceptable terms, if at
all, or that any such collaborations will be successful.

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. Some of these fluctuations may be significant.
As of March 31, 1996, the Company's accumulated deficit was $41.7 million.

RESULTS OF OPERATIONS

The Company had no revenues in the first quarter of 1996 or 1995. In September
1995, the Company received a one-time payment upon the execution of its
agreement with Leo as described above. There can be no assurance that the
Company will realize any further revenue from this arrangement or any other
collaborative arrangement.

For the three months ended March 31, 1996, research and development expenses
increased to $2.6 million from $2.1 million for the same period in 1995. The
increase was due primarily to manufacturing scale-up activities for the
Company's continuing clinical trials of LJP 394, additions to research and
development personnel, expansion of the Company's research and development
programs, and increased facilities expenditures. The Company's research and
development expenses are expected to increase significantly in the future as the
Company progresses in its development efforts on various drug candidates.

General and administrative expenses increased to $588,000 for the three months
ended March 31, 1996, from $429,000 for the same period in 1995. The increase
was primarily attributable to increased administrative staffing to support
increased clinical and research and development activities, and increased
facilities expenditures.

Interest income increased to $286,000 for the three months ended March 31, 1996
from $190,000 for the same period in 1995. The increase was due to higher
investment balances following receipt of the net proceeds of the Company's
public offering in June 1995, its sale of stock to a private investor in October
1995, and the initial payment from Leo in September 1995. For the three months
ended March 31, 1996, interest expense decreased to $57,000 from $86,000 for the
same period in 1995. The decrease was the result of decreases in the Company's
capital lease obligations as compared to the same period in 1995.

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 initial payment from Leo, and interest income on its invested cash balances.
As of March 31, 1996, the Company had raised $61.8 million since inception from
public and private sales of equity securities, net of issuance costs.

At March 31, 1996, the Company had $20.4 million in cash, cash equivalents and
short-term investments, as compared to $23.7 million at December 31, 1995. The
Company's working capital decreased to $19.0 million at March 31, 1996, from
$21.9 million at December 31, 1995. The decrease in working capital resulted
from the use of the Company's cash toward expenses of ongoing clinical and
research and development programs, and related general and administrative
expenses. The Company invests its cash in highly rated liquid debt instruments.

                          (A DEVELOPMENT STAGE COMPANY)

As of March 31, 1996, the Company had acquired an aggregate of $4.4 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 has no material commitments for the acquisition of
property and equipment.

The Company intends to use its financial resources to fund clinical trials,
research and development and manufacturing scale-up, and for working capital and
other general corporate purposes. In the near-term, anticipated expenses include
costs of additional clinical trials for LJP 394, the production of LJP 394 for
toxicology studies and clinical trials, 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 through 1997. However, the amounts expended by the Company for various
purposes may vary significantly, and it is possible that the Company's cash
requirements will exceed current projections and 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 magnitude of these
programs, the scope and results of preclinical testing and clinical trials, the
time and costs involved in obtaining 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 development and/or collaborative research arrangements, and the cost
of manufacturing scale-up and effective commercialization activities and
arrangements. The Company expects to incur significant 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, possible 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
its lead drug candidate, 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 and the Company has no other products that are expected
to become marketable in the next several years. 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 issuances of its securities, collaborative arrangements, and business
combinations. 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. Financing through the Company's existing collaborative arrangement is
uncertain as described above, and there can be no assurance that the Company
will be able to enter into any other collaborative relationships.
