1.       ORGANIZATION AND BASIS OF PRESENTATION

         ORGANIZATION

         Vical was incorporated in April 1987 and has devoted substantially all
         of its resources since that time to its research and development
         programs. The Company is currently focusing its resources on the
         development of its direct gene transfer and related technologies.

         BASIS OF PRESENTATION

         The information contained herein has been prepared in accordance with
         instructions for Form 10-Q. The information at September 30, 1998, and
         for the three-month and nine-month periods ended September 30, 1998 and
         1997, is unaudited. In the opinion of management, the information
         reflects all adjustments necessary to make the results of operations
         for the interim periods a fair statement of such operations. All such
         adjustments are of a normal recurring nature. Interim results are not
         necessarily indicative of results for a full year. The preparation of
         financial statements in conformity with generally accepted accounting
         principles requires management to make estimates and assumptions that
         affect the reported amounts of assets and liabilities and disclosures
         of contingent assets and liabilities at the date of the financial
         statements and the reported amounts of revenues and expenses during the
         reporting period. Actual results could differ from those estimates. For
         a presentation including all disclosures required by generally accepted
         accounting principles, these financial statements should be read in
         conjunction with the audited financial statements for the year ended
         December 31, 1997, included in the Vical Incorporated Form 10-K filed
         with the Securities and Exchange Commission.

2.       NET LOSS PER SHARE

         Net loss per share (basic and diluted) for the three-month and
         nine-month periods ended September 30, 1998 and 1997, has been computed
         using the weighted average number of common shares outstanding during
         the respective periods. Diluted loss per share does not include any
         assumed exercise of stock options as the effect would be antidilutive.

3.       COMPREHENSIVE INCOME

         The Company implemented Statement of Financial Accounting Standards No.
         130, "Comprehensive Income", effective January 1, 1998. This statement
         requires that all items that are required to be recognized under
         accounting standards as components of comprehensive income be reported
         in a financial statement that is displayed with the same prominence as
         other financial statements. Accordingly, in addition to reporting net
         income (loss) under the current rules, the Company is required to
         display the impact of any unrealized gain or loss on marketable
         securities as a component of comprehensive income and to display an
         amount representing total comprehensive income for each period
         presented. In interim financial results, this information is allowed to
         be presented in the notes to the financial statements. For the
         three-month periods ended September 30, 1998 and 1997, other
         comprehensive income was $148,889 and $61,663, respectively, and total
         comprehensive loss was $1,600,986 and $162,841, respectively. For the
         nine-month periods ended September 30, 1998 and 1997, other
         comprehensive income was $129,133 and $71,653, respectively, and total
         comprehensive loss was $5,276,558 and $4,442,007, respectively.

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


OVERVIEW

Vical was incorporated in April 1987 and has devoted substantially all of its 
resources since that time to its research and development programs. The 
Company is focusing its resources on the development of its direct gene 
transfer and related technologies. Currently, the Company is developing its 
ALLOVECTIN-7, LEUVECTIN and VAXID cancer product candidates internally, while 
developing vaccine product candidates for infectious diseases primarily in 
collaboration with corporate partners Merck & Co., Inc. ("Merck") and Pasteur 
Merieux Connaught ("PMC"). In February 1998, the Company and Centocor, Inc. 
entered into a license agreement allowing Centocor, Inc. to use Vical's naked 
DNA technology to develop and market certain gene-based vaccines for the 
potential treatment of certain types of cancer. To date, the Company has not 
received revenues from the sale of products. The Company expects to incur 
substantial operating losses for at least the next several years, due 
primarily to expansion of its research and development programs and the cost 
of preclinical studies and clinical trials. As of September 30, 1998, the 
Company's accumulated deficit was approximately $35.7 million.

Vical has formulated ALLOVECTIN-7, a complex containing the gene encoding a 
particular human histocompatibility antigen, HLA-B7, and a lipid material to 
facilitate gene uptake. After direct injection of ALLOVECTIN-7 into a tumor, 
the Company believes that the HLA-B7 gene will cause the tumor cells to 
produce the HLA-B7 antigen. This gene expression may then trigger a potent 
cellular immune response against the tumor cells.

In May 1998, the Company initiated registration-supportive expanded Phase II 
and Phase III multi-center clinical trials in certain patients with 
metastatic melanoma. Either or both of the pivotal trials could support 
initial product registration if endpoints are achieved. The FDA has reviewed 
data from previous studies and has confirmed acceptability of the designs, 
endpoints, and analysis plans for both new trials. The open-label, 
multi-center Phase II trial is designed to confirm the efficacy of 
ALLOVECTIN-7 in the defined patient population which appeared to benefit most 
in earlier Phase II trials. Enrollment will be open to patients with 
metastatic (spread beyond the initial site), refractory (unresponsive to 
standard therapy), Stage III or IV disease that has not yet spread to 
multiple internal organs. Up to 70 advanced melanoma patients will be 
enrolled at approximately 15 leading cancer treatment centers throughout 
North America. The objective is a clinical partial or complete response in at 
least 15 percent of the evaluable patients, persisting with a median duration 
of at least four months.

The open-label, multi-center, randomized, controlled Phase III trial is 
designed to determine the efficacy of ALLOVECTIN-7 when combined with 
standard chemotherapy in patients with unresectable, metastatic melanoma not 
previously treated with chemotherapy. In prior trials, ALLOVECTIN-7 was used 
only after standard therapies had failed. In the new trial, patients may be 
enrolled upon diagnosis or upon progression to Stage III or Stage IV disease 
when surgery or radiation therapy are usually no longer curative. Because 
ALLOVECTIN-7 is intended to trigger an immune response against tumor cells, 
the Company believes the treatment may be more effective in patients whose 
immune systems have not been compromised.

Approximately 140 patients per group, randomized by sex, age, and extent of
disease spread, will be enrolled into a chemotherapy-plus-ALLOVECTIN-7
experimental group or a chemotherapy-only control group. The objective is a
greater relative clinical benefit for the experimental group than for the
control group. Acceptable endpoints are either an improvement in the median time
to disease progression, or in the rate of objective clinical responses.


                                            7                                  



Results from another Phase I/II trial of ALLOVECTIN-7 suggested potential
efficacy in certain patients with unresectable head and neck cancer.
Results for 22 evaluable patients in a multi-center Phase II trial yielded 
one clinical complete response lasting more than 8 months. Eight patients 
experienced stable disease for 2 to 18 months and continuing, of which three 
patients had significant (25 percent to 40 percent) tumor shrinkage. The 
median time to disease progression was 26 weeks among the nine patients that 
derived clinical benefit, compared with 6 weeks among the 13 non-responders. 
Notably, median survival was 41 weeks among patients who derived clinical 
benefit, compared with 23 weeks among non-responders. Overall median survival 
for patients in the Phase II trial, including non-responders, was 36 weeks, 
which is more than 50 percent longer than the expected median survival (23 
weeks) for this patient population.

Vical is developing its second gene-based product candidate, LEUVECTIN, also
intended for direct injection into tumor lesions of cancer patients. LEUVECTIN
contains a gene that encodes the potent immunostimulator IL-2 and a lipid
material to facilitate gene uptake. The Company expects that LEUVECTIN, when
injected into tumors, will cause the malignant cells to produce and secrete IL-2
in the vicinity of the tumor, stimulating the patient's immune system to attack
and destroy tumor cells. Because LEUVECTIN is designed to deliver IL-2 only at
the site of tumor lesions, the Company believes that it may provide similar
efficacy with fewer side effects than systemic IL-2 therapy.

Phase I/II clinical trials testing the safety of LEUVECTIN at varying dosage 
levels were completed in patients with advanced melanoma, renal cell 
carcinoma, and soft-tissue sarcoma. The Phase I/II results presented in May 
1998 indicated that of the 14 evaluable patients in the renal cell carcinoma 
trial, two patients achieved clinical partial responses persisting for 13 to 
14 months and continuing, and two achieved stable disease, yielding a total 
of four out of 14 evaluable patients (29 percent) deriving clinical benefit 
from treatment. Among 16 evaluable patients in the melanoma trial, one 
achieved a clinical partial response persisting for 11 months and continuing, 
and three achieved stable disease. Among 15 evaluable patients in the sarcoma 
trial, nine patients achieved stable disease. The results of these trials 
indicated that the treatment appeared to be safe and well-tolerated, with no 
serious treatment-related adverse events reported. Responses appeared to be 
dose-related, with all clinical responses occurring in the two highest dosing 
groups. In May 1998 the Company initiated a multicenter Phase II clinical 
trial in patients with metastatic renal cell carcinoma. The open-label, 
multi-center Phase II trial is designed to evaluate the safety and efficacy 
of LEUVECTIN in up to 80 patients with metastatic kidney cancer and determine 
response rate and duration.

In June 1997, the Company initiated a Phase I/II clinical trial with 
LEUVECTIN in approximately 18 prostate cancer patients. The trial was 
designed to test the safety and efficacy of LEUVECTIN as a potential therapy 
for patients with tumors apparently confined to the prostate capsule, but 
with a high likelihood of metastatic disease recurrence. Treatment with 
LEUVECTIN was intended to stimulate a localized immune response against the 
primary tumor and a systemic immune response against any tumor cells that may 
have escaped from the capsule.

Data measurement and analysis focused on reductions in the patients' serum 
levels of prostate-specific antigen (PSA) following treatment with LEUVECTIN. 
PSA is a biochemical substance produced exclusively by prostate cancer cells 
and used as a marker to detect and monitor the disease. Recent studies have 
confirmed that PSA levels, in combination with several other factors, are 
highly predictive of disease progression in post-surgical and post-radiation 
patients.

Results of the trial were presented in June 1998, and indicated that 
LEUVECTIN was well-tolerated and may be successful in causing targeted immune 
response against prostate cancer cells. In five of 11 patients scheduled for 
radical prostatectomy (complete removal of the prostate gland), serum PSA 
levels decreased by at least 50 percent prior to surgery, and remained at 
undetectable levels following surgery for up to 11 months and continuing. Two 
additional patients experienced serum PSA reductions between 25 percent and 
50 percent prior to surgery and undetectable levels following surgery for up 
to 6 months and continuing. In four of eight patients with recurrent disease 
following radiation therapy, serum PSA levels decreased by at least 50 
percent. Three additional patients experienced serum PSA reductions between 
25 percent and 50 percent.

In collaboration with Dr. Ronald Levy of Stanford University Medical Center, 
the Company is developing a naked DNA anti-idiotype vaccine, VAXID, against 
low-grade non-Hodgkin's B-cell lymphoma. VAXID is a DNA plasmid that encodes 
the patient-specific idiotype of the B-cell tumor immunoglobulin. The Company 
believes that immunization of post-chemotherapy patients with VAXID could 
result in the elimination of residual disease and the prevention of the 
relapse of disease. In October 1997, a Phase I/II clinical trial of VAXID 
began at the Stanford University Medical Center under the direction of Dr. 
Levy.

In July 1998, the Company announced the initiation of a Phase I/II clinical 
trial to study the safety and potential efficacy of an experimental DNA 
vaccine for patients with metastatic melanoma. The trial is being sponsored 
by the National Cancer Institute under the direction of Dr. Steven A. 
Rosenberg, M.D., Ph.D., Chief of Surgery. The experimental vaccine contains a 
gene which may cause cells at the injection site to produce a modified gp100 
melanoma antigen. The antigen is expected to trigger an immune response 
against melanoma tumor cells. In earlier studies, Dr. Rosenberg tested a 
vaccine using peptides (portions of the modified antigen) in combination 
therapy with interleukin (IL-2), a naturally occurring protein that 
stimulates the immune system. A DNA vaccine may be more generally applicable 
and may provide advantages in manufacturing and product handling.

In July 1997, the Company and PMC began a Phase I clinical trial of an 
experimental naked DNA vaccine against the parasite that causes malaria. The 
Company and PMC sponsored the trial under their Research, Collaboration and 
License Agreement. The trial was conducted by the U.S. Naval Medical Research 
Institute. In April 1998, the Company released preliminary results from 
approximately 20 human participants in the trial which indicated that the 
vaccine was well-tolerated and safe. Preliminary analysis of specimens from 
trial participants suggested a good cellular immune response with features 
that the physicians conducting the trial believe may be important in 
preventing the disease. In the October 16, 1998, issue of SCIENCE, the 
Company and its collaborators at the Naval Medical Research Center and PMC 
reported that subjects immunized with a potential malaria DNA vaccine 
developed dose-related "killer" T cell immune responses. These T-cells are 
believed to be essential for vaccines against malaria and other infectious 
diseases. This was the first demonstration of safety and immune responses in 
healthy human volunteers with a vaccine using the Company's patented naked 
DNA technology. To date, no effective vaccine has been developed against 
malaria, which is among the most prevalent and fatal infectious diseases 
worldwide. In September 1998, the Company signed a cooperative agreement with 
the Office of Naval Research for funding of up to $2,700,000 to develop a 
multi-gene malaria DNA vaccine and test its ability to protect humans against 
malaria.

In September 1998, the Company and Boston Scientific Corporation entered into 
a license and option agreement for the development of intravascular gene 
delivery technology. The agreement specified an initial payment of $1,100,000 
which was received in October 1998.

The Company's product candidates may not prove to be safe and effective in 
clinical trials and no commercially successful products may ultimately be 
developed by the Company.

RESULTS OF OPERATIONS

Revenues of $1,696,000 were recorded for the quarter ended September 30, 
1998. License revenue primarily consisted of a license fee of $1,100,000 
(which the Company received in October 1998) related to a license and option 
agreement with Boston Scientific for the development of vascular gene 
therapy, recognition of deferred license fees of $250,000 from the existing 
Merial license agreement and royalty revenue of $183,000. In the second 
quarter of 1998, the Company received $1,000,000 from Merial for the 
extension of its option on vaccine targets. This license fee is being 
recognized as revenue over the twelve-month option period. Accordingly, 
$250,000 was recognized as revenue in each of the second and third quarters 
of 1998 and $500,000 of the initial payment is reflected as current deferred 
revenue in the balance sheet at September 30, 1998. In addition, for the 
quarter ended September 30, 1998, the Company recognized net contract revenue 
of $159,000, primarily from a contract entered into in September 1998 with 
the Office of Naval Research for the development work on a potential naked 
DNA vaccine to prevent malaria. This multi-year grant could provide up to 
$2,700,000 of funding to the Company.

The Company had revenues of $3,480,000 for the quarter ended September 30, 
1997. License revenue of $3,178,000 was derived primarily from an initial 
payment of $2,000,000 from Merck under a license and option agreement for use 
of the Company's technology to deliver certain growth factors and a milestone 
payment from PMC for the start of the malaria clinical trial. License revenue 
for the quarter ended September 30, 1997, also included amortization of 
deferred license fees under earlier agreements with PMC and Merial and 
royalty revenues of $171,000. Contract revenues were primarily from PMC.

Revenues for the nine months ended September 30, 1998, were $4,988,000. In 
addition to the revenue recognized in the third quarter, revenue for the nine 
months ended September 30, 1998, also included $2,200,000 of license revenue 
from Centocor, Inc., $428,000 of license revenue from amortization of 
deferred revenue from PMC and Merial, contract revenue from PMC and royalty 
revenue of $524,000. Revenues for the nine months ended September 30, 1997, 
were $5,473,000 and, in addition to contract and license revenue from Merck, 
PMC and Merial, and royalty revenue, included a grant from the Department of 
Defense of $209,000.

The Company's total operating expenses for the quarter ended September 30, 
1998, were $4,012,000 compared with $4,247,000 for the second quarter of 
1997. Total operating expenses for the nine months ended September 30, 1998, 
were $12,147,000 compared with $11,616,000 for the same period in 1997.

Research and development expenses decreased to $3,158,000 for the three 
months ended September 30, 1998, from $3,319,000 for the same period in 1997. 
For the nine months ended September 30, 1998, research and development 
expenses were $9,311,000 compared with $8,911,000 in the same period of 1997. 
The decrease in research and development expenses for the quarter ended 
September 30, 1998 is because the comparable quarter of the prior year 
included clinical trial costs for the malaria clinical trial and costs for 
contract services which were not incurred at the same level in 1998. These 
decreases were partially offset by increased costs of personnel. The increase 
in research and development expenses for the nine months ended September 30, 
1998 was generally due to increased clinical trial costs and additional 
royalties for license agreements.

General and administrative expenses decreased to $855,000 for the three 
months ended September 30, 1998, from $928,000 for the same period in 1997. 
General and administrative expenses for the nine months ended September 30, 
1998, increased to $2,836,000 from $2,705,000 for the same period in 1997. 
The decrease for the three-month period primarily is due to lower insurance 
and facilities costs. The increase for the nine-month period is attributable 
to the Company's expanding research and development activities, partially 
offset by lower insurance and facilities costs.

Investment income for the three-month and nine-month periods ended September 
30, 1998, was $608,000 and $1,879,000, respectively. Investment income for 
the three-month and nine-month periods ended September 30, 1997, was $591,000 
and $1,798,000, respectively. The increases are primarily a result of higher 
rates of return on investments.

The net loss was $.11 per share for the three months ended September 30, 
1998, compared with net loss per share of $.01 for the same period of 1997. 
For the nine months ended September 30, 1998, the net loss was $.34 per share 
compared with a net loss of $.29 per share for the same period in the prior 
year. The Company expects to incur losses throughout the remainder of 1998 
and to report a net loss per share for the year ended December 31, 1998.

LIQUIDITY AND CAPITAL RESOURCES

Since its inception, Vical has financed its operations primarily through 
private placements of preferred and common stock, three public offerings of 
common stock and revenues from collaborative agreements. As of September 30, 
1998, the Company had working capital of approximately $40.5 million compared 
with $44.9 million at December 31, 1997. Cash and marketable securities 
totaled approximately $40.9 million at September 30, 1998, compared with 
$45.6 million at December 31, 1997.

The Company expects to incur substantial additional research and development 
expense including continued increases in personnel costs and costs related to 
preclinical testing and clinical trials. The Company's future capital 
requirements will depend on many factors, including continued scientific 
progress in its research and development programs, the scope and results of 
preclinical testing and clinical trials, the time and costs involved in 
obtaining regulatory approvals, the costs involved in filing, prosecuting and 
enforcing patent claims, competing technological and market developments, the 
cost of manufacturing and scale-up, and commercialization activities and 
arrangements. The Company intends to seek additional funding through research 
and development relationships with suitable potential corporate collaborators 
or through public or private financing. Additional funding may not be 
available on favorable terms or at all.

If additional funding is not available, Vical anticipates that its available 
cash and existing sources of funding will be adequate to satisfy its 
operating needs through 2000.

YEAR 2000 ISSUES

The Company has performed a review of its computer applications and equipment 
to determine whether they will function for the year 2000 and beyond and what 
modifications, if any, would be required to ensure their continuing 
functionality. Given the relatively small size of the Company's systems and 
the predominantly new hardware, software and operating systems, management 
does not anticipate any significant delays in becoming Year 2000 compliant. 
However, the Company is unable to control whether its current and future 
strategic partners' systems are Year 2000 compliant. To the extent that 
strategic partners would be unable to procure clinical materials or services 
provided by the Company, or otherwise manage their clinical trials and 
research and development activities, or to pay invoices owed to the Company, 
or to the extent that suppliers are unable to manufacture and ship materials 
or provide requested contract services, the Company's operations could be 
adversely affected. The Company is communicating with strategic partners to 
assess the risk of Year 2000 issues. The Company has not completed the 
inquiries of the strategic partners. However, the Company is not aware, at 
this time, of any material year 2000 issues regarding its dealings with its 
strategic partners. The Company anticipates that its assessment will be 
completed by July 31, 1999. At this time, management has no reason to believe 
that Year 2000 changes will have a material impact on the Company's business, 
financial condition or results of operations. Since no significant issues 
have been identified, the Company does not have a contingency plan to address 
any material Year 2000 issues. Such contingency plan, if required, will be 
developed for all applications and systems that affect core business 
functions upon completion of the Company's assessment of Year 2000 issues.
