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

Any statements made by NeoPharm Inc. (the "Company") in this quarterly report
that are forward looking are made pursuant to the safe harbor provisions of the
Private Securities Litigation Reform Act of 1995. The Company cautions readers
that important factors may affect the Company's actual results and could cause
such results to differ materially from forward-looking statements made by or on
behalf of the Company. Such factors include, but are not limited to, changing
market conditions, the impact of competitive products and pricing, the timely
development, approval by the Food and Drug Administration ("FDA") and foreign
health authorities, and market acceptance of the Company's products in
development, the Company's ability to further raise capital, the Company's
dependence on key personnel, and other factors referenced under "Risk Factors"
in the Company's Annual Report on Form 10-K for the fiscal year ended December
31, 1998

OVERVIEW

         NeoPharm is a pharmaceutical Company engaged in the research and
development of drugs for the diagnosis and treatment of various forms of cancer.
Presently the Company has several drugs which are in varying stages of
development; BudR (Broxuridine), liposome encapsulated doxorubicin ("LED"),
liposome encapsulated paclitaxel ("LEP"), liposome encapsulated antisense
oligodeoxynucleotide ("LE-AON" and with LED and LEP the "Liposome Products"),
IL-13 PE38QQR ("IL-13") and Mesothelin ss-(dsFv)-PE38 ("Mesothelin Mab"). IL-13
and Mesothelin Mab are both Ligand Target Cytotoxins that specifically target
cancer cells and leave normal cells unaffected.

         The Company has obtained rights to its various products as a result of
agreements and relationships entered into with various third parties including
the National Cancer Institute ("NCI"), the United States Food and Drug
Administration ("FDA"), the National Institute of Health ("NIH") and Georgetown
University.

         To date, the Company has been engaged primarily in research and
development of its developmental stage products. The Company has developed
expertise in identification, development and preparation for regulatory approval
of cancer drugs for both therapeutic and diagnostic purposes, although the
Company has no products that are currently approved for sale. The Company
currently has no marketing or sales staff and has conducted its activities
primarily through consultants and at university research facilities. Through
March 31, 1999, with the exception of license fees, the Company has not
generated any revenue from operations.

         NeoPharm, Inc., was incorporated in Delaware under the name OncoMed,
Inc. in June 1990, and changed its name to NeoPharm, Inc. in March, 1995.

NEOPHARM PRODUCTS

         The Company's Liposome Products consist of spheres of subcellular size
composed primarily of phospholipids, certain of which are the primary components
of living cell membranes, and can be made to contain and deliver drugs. This
membrane encapsulation feature of liposomes enables the entrapped drug to be
circulated in the bloodstream in higher concentrations for longer periods of
time than the free drug. When certain drugs, including chemotherapeutic agents,
are administered in conjunction with liposomes, they have been shown to produce
fewer and less severe local and systematic side effects. Although liposomes have
been

                                                                               8
<PAGE>

investigated and used for many years as drug delivery systems, the difficulty in
producing liposomes on a large scale, as well as the limited shelf life of many
liposomes, have limited their use in clinical settings.

         The Company's LED is currently under development in three Phase II
trials. The Company started a Phase II trial in hormone refractory prostate
cancer patients in June 1998. The Company is also starting an additional trial
in osteosarcoma (bone cancer) at higher doses of LED. These Phase II trials will
be conducted in several cancer centers in the United States. The Company has
also initiated a multi-center Phase II trial of LED in breast cancer patients
who have failed most of the chemotherapy protocols to appreciate the capacity of
LED in overcoming MDR in those patients. The Company also has a clinical trial
with LED in myeloma, a blood cancer. The Company has also initiated a Phase I
clinical study on LEP in September of 1998 for patients with lung cancer. These
trials are on-going at this time.

         In February 1999, the Company signed a License Agreement with 
Pharmacia and Upjohn ("P&U") to develop and commercialize LEP and LED 
worldwide. The Company received a $9,000,000 nonrefundable up-front payment 
upon execution of the License Agreement and will receive milestone payments 
as clinical progress occurs under the License Agreement, which could 
aggregate, if all milestone targets were to be achieved, $52,000,000. The 
Company will also receive royalties on overseas sales and a co-promotion 
profit split on sales in the United States. Pursuant to the License 
Agreement, P&U will assume all further responsibility for, and the costs 
associated with, the further development and testing of LED and LEP and the 
obtaining of all regulatory approvals. In addition, the Company has agreed to 
sell $8,000,000 of its common stock to P&U when certain Investigatory New 
Drug ("IND") applications are transferred to P&U in accordance with a 
separate Stock Purchase Agreement at a price per share equal to 110% of the 
then market price of the common stock during the sixty (60) day period 
preceeding the transfer of the INDs. The Company anticipates that the INDs 
will be transferred and the stock will then be issued and the cash proceeds 
received by early in the 3rd quarter of 1999.

         The Company has two license and research agreements with Georgetown
University that cover the use of certain technologies used in the Company's LED
and LEP products. In January 1999, the Company and Georgetown University agreed
to amend the agreements to reduce the level of future sublicense royalties on
LEP and LED sales payable to Georgetown in return for a one time sublicense fee
of $800,000. The Company made the $800,000 payment to Georgetown in March 1999,
after the execution of the P&U agreement. Additionally, the Company paid a 
one time bonus to employees of approximately $180,000 upon the execution of 
the P&U agreement.

         In October 1997, the Company entered into an exclusive worldwide 
licensing agreement with the FDA and the NIH to develop and commercialize a 
chimeric human protein known as "IL13-PE38QQR." The National Institute of 
Health received a $75,000 non-refundable license issue payment upon execution 
of the agreement and will receive minimum annual royalty payments of $10,000, 
which increase to $25,000 after our first commercial sale. The National 
Institute of Health license also provides for milestone payments which, if 
all milestones were to be attained, would require payments aggregating to 
$785,000 and royalties of 4% based on future product sales, if any. We are 
also required to pay the costs of filing and maintaining product patents on 
the licensed products as they are incurred.

         Extensive research by the scientists at FDA and NCI have demonstrated
that some solid human tumors such as kidney cancer (renal cell carcinoma), brain
cancer (glioblastoma), Kaposi's sarcoma and breast carcinoma express high
numbers of IL-13 receptors on their cell surfaces. These receptor sites become a
specific target for the IL-13 chimeric protein for inducing cytotoxicity at
nanogram concentration. On the other hand, normal organs of the body are shown
to exhibit minimal receptors sites thereby sparing these organs from any toxic
effect.

                                                                               9
<PAGE>

The Company expects to scale up the production of this chimeric protein to
complete preclinical studies in the second quarter of 1999 to be followed later
in the year by Phase I clinical program in humans with renal cell carcinoma and
glioblastoma.

         The Company also recently entered into a Licensing Agreement with 
the NIH for Mesothelin Mab for head and neck cancer and mesothelioma. Like 
IL-13, Mesothelin Mab targets mesothelin receptors on cancer cells and 
delivers a cytotoxin to destroy the cancer cell while leaving normal cells 
alone. Mesothelin Mab is expected to enter Phase I Clinical Studies in the 
later part of 1999. The terms and conditions of the Mesothelin Mab License 
Agreements with the National Institute of Health are substantially the same 
as those described above for our agreement with the National Institute of 
Health for IL-13 chimeric protein-therapy, with the exception that milestone 
payments by the Company (if all milestones were to be attained) would 
aggregate to $500,000. The royalty payable on future product sales, if any, 
would be 5% and the Company has agreed to reimburse the National Institute of 
Health, within 60 days of a request for reimbursement, for up to $175,000 of 
previously incurred patent prosecution costs.

         Clinical trials involving prognostic use of BUdR have indicated that
the information regarding tumor cell behavior provided by BUdR can assist the
oncologist in selecting appropriate therapeutic regimens for the patients and
enable better monitoring of the effectiveness of the chosen therapy.

         In December 1996, the Company filed an NDA with the FDA for BUdR as a
prognostic agent in the treatment of breast cancer. The Company's NDA as it
relates to BUdR as a prognostic indication in the treatment of breast cancer was
accepted for review by the FDA and was reviewed by the FDA's Oncology Advisory
Committee ("ODAC") on December 19, 1997, at which time ODAC voted not to
recommend this indication to the FDA for approval. Since the ODAC action, the
Company has met with the FDA to respond to concerns raised by ODAC for the
purpose of continuing to pursue FDA approval. Based on these discussions the
Company is gathering additional data and reanalyzing the existing data in order
to obtain the FDA's approval of the Company's NDA. The original NDA was filed in
December 1996. The application has already been extended once and the Company
was informed on March 31, 1998 that the time for processing the original
application has expired. The Company is continuing to work with FDA to explore
the requirements for a prognostic application. Additionally, the Company is 
exploring opportunities to license and/or sell its BUdR product.

RESULTS OF OPERATIONS - THREE MONTHS ENDED MARCH 31, 1999 VS. THREE MONTHS ENDED
MARCH 31, 1998

         For the three month period ended March 31, 1999, the Company received a
nonrefundable license fee of $9,000,000 related to the licensing agreement with
P&U for the development and commercialization of the Company's LEP and LED
products. The Company recorded no revenue for the three month period ended March
31, 1998.

         Research and development expense for the three month period ended 
March 31, 1999 were $1,500,434 compared to $172,527 for the same period in 
1998. Research and development spending increased primarily due to expenses 
for the addition of clinical staff to manage the ongoing clinical trials of 
$148,000, nonrecurring expenses associated with the licensing of Mesothelin 
Mab of $256,000, the sublicense fee paid to Georgetown of $800,000 and bonus 
payments to employees based upon milestone acheivement of $100,000.

         General and administrative expenses for the three month period ended
March 31, 1999 were $597,994 compared to $291,966 for the same period in 1998.
General and administrative

                                                                              10

expense increased primarily due to additional payroll costs of $23,000, bonus
payments to employees based upon milestone achievements of $79,000, additional
insurance costs of $47,000 due to expanded coverages, increased investor
relation activities of $19,000 and increased professional fees of $125,000
related to licensing activities and other corporate matters, part of which 
are nonrecurring.

         The Company generated interest income on exess cash balances of $35,007
and $37,382 for the three month periods ended March 31, 1999 and March 31, 1998
respectively.

         The Company incurred $1,860 of interest expense during the three month
period ended March 31, 1999. The Company recorded no interest expense for the
same period in 1998.

         The Company recorded income tax expense of $2,774,000 for the three 
month period ended March 31, 1999. No income tax expense was recorded for the 
comparable period in the prior year.

         Net income for the three months ended March 31, 1999 was $4,160,719
compared to a net loss of $427,111 for the three month period ended March 31,
1998.

         Net income per share for the three month period ended March 31, 1999 
was $0.49 basic and $0.38 diluted compared to net loss per share of $0.05 
basic and diluted for the three months ended March 31, 1998.

LIQUIDITY AND CAPITAL RESOURCES

         Cash expenditures exceeded revenues from the Company's inception until
the 1st Quarter of 1999. Operations have principally been funded through a loan
from the Company's Chairman, a bank line-of-credit and since January 1996, the
initial public offering of common stock. The Company expects to incur additional
expenses, resulting in potentially significant losses, as it continues and
expands its research and development activities and undertakes additional
clinical trials of compounds obtained under proprietary licenses. The Company
also expects to incur substantial administrative and commercialization
expenditures in the future as it seeks FDA approval of drugs under development
and initiates marketing activities.

         From October 1998 through February 1999 the Company had a $3,000,000
line of credit in place with the John N. Kappor Trust dtd 9/20/89, an entity
affiliated with the Company's Chairman. The Company borrowed $250,000 on the
line of credit on January 8, 1999. The $250,000 plus accrued interest of $1,062
was repaid on January 29, 1999. The line of credit terminated upon the signing
of the licensing agreement with P&U on February 19, 1999.

         At March 31, 1999, the Company's cash and cash equivalents were
$7,402,048 compared to $40,681 at December 31, 1998. This increase in cash and
cash equivalents of $7,361,367 was the result of cash generated by operating
activities of $7,176,690, cash used to purchase equipment and furniture of $725
and cash provided by financing activities of $185,402. The Company plans to
finance its immediate needs principally from its existing capital resources and
interest thereon, and to the extent available, through collaborative agreements
with corporate partners and future public and private financing. The Company's
long term capital needs will require substantial additional funding in order to
continue its research and product development programs. The Company's long-term
capital requirements and the adequacy of its available funds will depend upon
many factors, including results of research and development, results of product
testing, relationships with potential partnerships and collaborations, and the
FDA regulatory process. No assurance can be given that additional funding will
be available when

                                                                              11

needed or on terms acceptable to the Company. Insufficient funds may require the
Company to delay, scale-back or eliminate certain of its research and
development programs or to license third parties to commercialize products or
technologies that the Company would otherwise undertake itself.

THE YEAR 2000 ISSUE

         The Year 2000 issue is the result of computer programs being written
using two digits rather than four to define the applicable year. Computer
equipment software and devices with imbedded technology that are time sensitive
may treat years as occurring between 1900 and the end of 1999 and may not
self-convert to reflect the upcoming change in the century. If not corrected,
this problem could result in system failures or miscalculations and erroneous
results by, or at, Year 2000.

         The Company conducted an assessment of its business systems that could
encounter Year 2000 problems. This assessment included both information
technology systems and non-information technology systems. Based on this
internal assessment, the Company has not identified any material year 2000
issues. The Company retained an outside consultant to review its assessment. The
consultant recommended several minor corrective measures which are in the
process of being completed. The cost of the review and corrective measures is
expected to be less than $5,000.

         Because the Company expects that its internal systems will be Year 2000
compliant, the Company belives that the most likely worst case scenario would
result from third parties failing to achieve Year 2000 compliance. The Company
relies on vendors, service providers and collaboration partners for raw
materials, contract manufacturing, research activities, product testing,
clinical trials, administrative services and other services ("Service
Providers"). The Company is in the process of surveying its Service Providers to
determine if they are Year 2000 compliant or have effective plans in place to
address the Year 2000 issue and to determine the extent of the Company's
vulnerability to the failure of its Service Providers to remedy such issues.
Based upon the responses that the Company receives from its Service Providers,
the Company will assess its risks and develop appropriate contingency plans as
needed. The Company does not currently have a contingency plan in place; however
it is the Company's intention to complete its contingency plan by October 31,
1999.

         The Company does not expect the Year 2000 issue to have a material
adverse impact on the Company's business or results of operations. However, no
assurance can be given that unanticipated or undiscovered Year 2000 problems
will not arise that could have a material adverse effect on the Company's
business and results of operations. In addition, there can be no assurance that
Year 2000 non-compliance by any of the Company's significant Service Providers
will not have a material adverse effect on the Company's business or results of
operations.

     5.03   Licensee agrees, after First Commercial Sale, to make reasonable
            quantities of Licensed Products or materials produced through the
            use of Licensed Processes available on a compassionate use basis to

            patients and physicians detailing the Licensed Products and/or
            medical aspects and the therapeutic treatment(s) of ovarian
            carcinomas and mesotheliomas.

     5.05   Licensee acknowledge that PHS may enter into future Cooperative
            Research and Development Agreements (CRADAs) under the Federal
            Technology Transfer Act of 1986 that relate to the subject matter
            of this Agreement.  Licensee agrees not to unreasonably deny
            requests for a Research License from such future collaborators with

            Cooperative Research and Development Agreement (CRADA) project
            feasible. Licensee may request an opportunity to join as a party to
            the proposed Cooperative Research and Development Agreement
            (CRADA).

     5.06   (a)     In addition to the reserved license of Paragraph 5.01 above,
                    PHS reserves the right to grant nonexclusive Research
                    License directly or to require Licensee to grant
                    nonexclusive Research License on reasonable terms. The
                    purpose of this Research License is to encourage basic
                    research, whether conducted at an academic or corporate
                    facility. In order to safeguard the Licensed Patent Rights,
                    however,  PHS shall consult with Licensee before granting to
                    commercial entities a Research License or providing to them
                    research samples of materials made through the Licensed
                    Processes.

            b) In exceptional circumstances, and in the event that Licensed
               Patent Rights are Subject Inventions made under a
               Cooperative Research and Development Agreement (CRADA), the
               Government, pursuant to 15 U.S.C. 3710a(b)(1)(B), retains
               the right to require the Licensee to grant to a responsible
               applicant a nonexclusive, partially exclusive, or exclusive
               sublicensee to use Licensed Patent Rights in Licensee's
               field of use on terms that are reasonable under the
               circumstances; or if Licensee fails to grant such a license,
               the Government retains the right to grant the license
               itself. The exercise of such rights by the Government shall
               only be in exceptional circumstances and only if the
               Government determines (1) the action is necessary to meet
               health or safety needs that are not reasonably satisfied by
               Licensee, (ii) the action is necessary to meet requirements
               for public use specified by Federal regulations, and such
               requirements are not reasonably satisfied by the Licensee;
               or (iii) the Licensee has failed to comply with an agreement
               containing provisions described in 15 U.S.C. 3710a(c)(4)(B).
               The determination made by the Government under this 


                                    8

               Article is subject to administrative appeal and judicial review
               under 35 U.S.C. 203(2).

6.   ROYALTIES AND REIMBURSEMENT

     6.01   Licensee agrees to pay to PHS a noncreditable, nonrefundable
            license issue royalty as set forth in Appendix C within thirty (30)
            days from the date that this Agreement becomes effective.

     6.02   Licensee agrees to pay to PHS a nonrefundable minimum annual
            royalty as set forth in Appendix C. The minimum annual royalty is
            due and payable on January 1 of each calendar year and may be
            credited against any earned royalties due for sales made in that
            year. The minimum annual royalty due for the first calendar year of
            this Agreement may be prorated according to the fraction of the
            calendar year remaining between the effective date of this
            Agreement and the next subsequent January 1.

     6.03   Licensee agrees to pay PHS earned royalties as set forth in
            Appendix C.

     6.04   Licensee agrees to pay PHS benchmark royalties as set forth in
            Appendix C.

     6.05   Licensee agrees to pay PHS sublicensing royalties as set forth in
            Appendix C.

     6.06   A patent or patent application licensed under this Agreement shall
            cease to fall within the Licensed Patent Rights and/or Background
            Patent Rights for the purpose of computing earned royally payments
            in any given country on the earliest of the dates that a) the
            application has been abandoned and not continued, b) the patent
            expires or irrevocably lapses, or c) the claim has been held to be
            invalid or unenforceable by an unappealed or unappealable decision
            of a court of competent jurisdiction or administrative agency.

     6.07   No multiple royalties shall be payable because any Licensed
            Products or Licensed Processes are covered by more than one of the
            Licensed Patent Rights and Background Patent Rights.

     6.08   (a)     Transfer of Licensed Products by Licensee to sublicensees or
                    an Affiliated party made in other than an arm's-length for
                    no furler resale shall be attributed a value which would
                    have been recovered in an arm's length transaction of like
                    quantity and quality of products sold on or about the time
                    of the transfer of Licensed Products for the purpose of
                    calculating Net Sales.

     6.08   (b)     Transfer of Licensed Products by Licensee to sublicensees or
                    Affiliated party for furler resale shalt have attributed
                    either a value which would have been received in an arm's-
                    length transaction based on sales or like 


                                      9
<PAGE>


                    quantity and quality of products transferred on or about 
                    the time of each transfer of Licensed Products or the 
                    actual value received in a later arm's length transaction, 
                    whichever is greater, for purposes of calculating Net Sales.

     6.09   With regard to expenses associated with the preparation, filing,
            prosecution, and maintenance of all patent applications and patents
            included within the Licensed Patent Rights and Background Patent
            Rights incurred by PHS prior to the effective date of this
            Agreement, Licensee shall pay to PHS, as an additional royalty,
            within sixty (60) days of PHS's submission of a statement and
            request for payment to Licensee, an amount equivalent to such
            patent expenses previously incurred by PHS and detailed in Appendix
            G.

     6.10   With regard to expenses associated with the preparation, filing,
            prosecution, and maintenance of all patent applications and patents
            included within the Licensed Patent Rights and Background Patent
            Rights incurred by PHS on or after the effective date of this
            Agreement, PHS, at its sole option, may require Licensee:

            (a) to pay PHS on an annual basis, within sixty (60) days of PHS's 
            submission of a statement and request for payment, a royalty amount
            equivalent to all such patent expenses incurred during the previous
            calendar year(s); or

            (b) to pay such expenses directly to the law firm employed by PHS
            to handle such functions. However, in such event, PHS and not
            Licensee shall be the client of such law firm.

            In limited circumstances, Licensee may be given the right to assume
            responsibility for the preparation, filing, prosecution, or
            maintenance of any patent application or patent included with the
            Licensed Patent Rights.  In that event, Licensee shall directly pay
            the attorneys or agents engaged to prepare, file, prosecute, or
            maintain such patent applications or patents and shall provide to
            PHS copies of each invoice associated with such services as well as
            documentation that such invoices have been paid.

     6.11   Licensee may elect to surrender its rights in any country of the
            Licensed Territory under any Licensed Patent Rights and Background
            Patent Rights upon ninety (90) days written notice to PHS and owe
            no payment obligation under Article 6.10 for patent-related
            expenses incurred in that country after ninety (90) days of the
            effective date of such written notice.

7.   PATENT FILING, PROSECUTION, AND MAINTENANCE

     7.01   Except as otherwise provided in this Article 7, PHS agrees to take
            responsibility for, but to consult with, the Licensee in the
            preparation, filing, prosecution, and maintenance of any and all
            patent applications or patents included in the Licensed 


                                      10
<PAGE>

            Patent Rights and shall furnish copies of relevant patent-related
            documents to Licensee.

     7.02   Upon PHS's written request, Licensee shall assume the
            responsibility for the preparation, filing, prosecution, end
            maintenance of any and all patent applications or patents included
            in the Licensed Patent Rights and shall on an ongoing basis
            promptly furnish copies of all patent-related documents to PHS. In
            such event, Licensee shall, subject to the prior Approval of PHS,
            select registered patent attorneys or patent agents to provide such
            services on behalf of Licensee and PHS.  PHS shall provide
            appropriate powers of attorney and other documents necessary to
            undertake such actions to the patent attorneys or patent agents
            providing such services. Licensee and its attorneys or agents shall
            consort with PHS in all aspects of the preparation, filing,
            prosecution and maintenance of patent applications and patents
            included within the Licensed Patent Rights and shall provide PHS
            sufficient opportunity to comment on any document that Licensee
            intends to file or to cause to be filed with the relevant
            intellectual property or patent office.

     7.03   At any time, PHS may provide Licensee with written notice that PHS
            wishes to assume control of the preparation, filing, prosecution,
            and maintenance of any and all patent applications or patents
            included in the Licensed Patent Rights.  If PHS elects to assume
            such responsibilities, Licensee agrees to cooperate fully with PHS,
            its attorneys, and agents in the preparation, filing, prosecution,
            and  maintenance of any and all patent applications or patents
            included in the Licensed Patent Rights and to provide PHS with
            complete copies of any and all documents or other materials that
            PHS deems necessary to undertake such responsibilities. Licensee
            shall be responsible for all costs associated with transferring
            patent prosecution responsibilities to an attorney or agent of
            PHS's choice.

     7 04   Each park shall promptly inform the other as to all matters that
            come to its attention that may affect the preparation, filing,
            prosecution, or maintenance of the Licensed Patent Rights and
            permit each other to provide comments and suggestions with respect
            to the preparation, filing, prosecution, and maintenance of
            Licensed Patent Rights, which comments and suggestions shall be
            considered by the other party.

8.   RECORDKEEPING

     8.01   Licensee agrees to keep accurate and correct records of Licensed
            Products made, used, sold, or imported and Licensed Processes
            practiced under this Agreement appropriate to determine the amount
            of royalties due PHS. Such records shall be retained for at least
            five (5) years following a given reporting period and shall be
            available during normal business hours for inspection at the
            expense of PHS by an accountant or other designated auditor
            selected by PHS for the sole purpose of verifying reports and
            payments hereunder. The accountant or auditor shall only 


                                      11
<PAGE>


            disclose to PHS information relating to the accuracy of reports 
            and payments made under this Agreement. If an inspection shows an 
            under reporting or underpayment in excess of five percent (5%/0) 
            for any twelve (12) month period, then Licensee shall reimburse 
            PHS for the cost of the inspection at the time Licensee pays the 
            unreported royalties, including any late charges as required by 
            Paragraph 9.08 of this Agreement. All payments required under 
            this Paragraph shall be due within thirty (30) days of the date 
            PHS provides Licensee notice of the payment due.

     8.02   Licensee agrees to have an audit of sales end royalties conducted
            by an independent auditor at least every two (2) years if annual
            sales of the Licensed Product or Licensed Processes are over two
            (2) million dollars. The audit shall address, at a minimum, the
            amount of gross sales by or on behalf of Licensee during the audit
            period, terms of the license as to percentage or fixed royalty to
            be remitted to the Government, the amount of royalty funds owed to
            the Government under this Agreement, and whether the royalty amount
            owed has  been paid to the Government and is reflected in the
            records of the Licensee. The audit shall also indicate the PHS
            license number, product, and the time period being audited. A
            report certified by the auditor shall be submitted promptly by the
            auditor directly to PHS on completion. Licensee shall pay for the
            entire cost of the audit.

9.   REPORTS ON PROGRESS BENCHMARKS, SALES AND PAYMENTS

     9.01   Prior to signing this Agreement, Licensee has provided to PHS the
            Commercial Development Plan at Appendix F, under which Licensee
            intends to bring the subject matter of the Licensed Patent Rights
            and/or Background Patent Rights to the point of Practical
            Application. This Commercial Development Plan is hereby
            incorporated by reference into this Agreement. Based on this plan,
            performance Benchmarks are determined as specified in Appendix E.

     9.02   Licensee shall provide written annual reports on its product
            development progress or efforts to commercialize under the
            Commercial Development Plan for each of the Licensed Fields of Use
            within sixty (60) days after December 31 of each calendar year.
            These progress reports shall include, but not be limited to:
            progress on research and development, status of applications for
            regulatory approvals, manufacturing, sublicensing, marketing,
            importing, and sales during the preceding calendar year, as well as
            plans far the present calendar year. PHS also encourages these
            reports to include information on any of Licensee's public service
            activities that relate to the Licensed Patent Rights and Background
            Patent Rights. If reported progress differs from that projected in
            the Commercial Development Plan and Benchmarks, Licensee shall
            explain the reasons for such differences. In any such annual
            report, Licensee may propose amendments to the Commercial
            Development Plan, acceptance of which by PHS may not be denied
            unreasonably. Licensee agrees to provide any additional information
            reasonably required by PHS to evaluate Licensee's performance under
            this Agreement. Licensee may 


                                      12
<PAGE>


            amend the Benchmark at any time upon written consent by PHS. PHS 
            shall not unreasonably withhold approval of any request of 
            Licensee to extend the time periods of this schedule if such 
            request is supported by a reasonable showing by Licensee of 
            diligence in its performance under the Commercial Development 
            Plan and toward bringing the Licensed Products to the point of 
            Practical Application as defined in 37 CFR 404.3(d). Licensee 
            shall amend the Commercial Development Plan and Benchmarks at the 
            request of PHS to address any Licensed fields of Use not 
            specifically addressed in the plan originally submitted.

     9.03   Licensee shall report to PHS the dates for achieving Benchmarks
            specified in Appendix E and the First Commercial Sale in each
            country in the Incensed Territory within thirty (30) days of such
            occurrences.

     9.04   Licensee shall submit to PHS within sixty (60) days after each
            calendar half-year ending June 30 and December 31 a royalty report
            setting forth for the preceding half-year period the amount of the
            Licensed Products sold or Licensed Processes practiced by or on
            behalf of Licensee in each country within the Licensed Territory,
            the Net Sales, and the amount of royalty accordingly due. With each
            such royalty report, Licensee shall submit payment of the earned
            royalties due. If no earned royalties are due to PHS for any
            reporting period, the written report shall so state. The royalty
            report shall be recorded as correct by an authorized officer of
            Licensee and shall include a detailed listing of all deductions
            made under Paragraph 2.10 to determine Net Sales made under Article
            6 to determine royalties due.

     9.05   Licensee agrees to forward semi-annually to PHS a copy of such
            reports received by Licensee from its sublicensees during the
            preceding half-year period as shall be pertinent to a royalty
            accounting to PHS by Licensee for activities under the sublicensee.

     9.06   Royalties due under Article 6 shall be paid in U.S. dollars. For
            conversion of foreign currency to U.S. dollars, the conversion rate
            shall be the New York foreign exchange rate quoted in THE WALL
            STREET JOURNAL on the day that the payment is due. All checks and
            bank drafts shall be drawn on United States banks and shall be
            payable, as appropriate, to "NIH/Patent Licensing." All such
            payments shall be sent to the following address: NIH, P.O. Box
            360120, Pittsburgh, PA 15251-6120.  Any loss of exchange, value,
            taxes, or other expenses incurred in the transfer or conversion to
            U.S. dollars shall be paid entirely by Licensee.  The royalty
            report required by Paragraph 9.04 of this Agreement shall accompany
            each such payment, and a copy of such report shall also be mailed
            to PHS at its address for notices indicated on the Signature Page
            of this Agreement.


                                      13
<PAGE>


     9.07   Licensee shall be solely responsible for determining if any tax on
            royalty income is owed outside the United States and shall pay any
            such tax and be responsible for all filings with appropriate
            agencies of foreign governments.

     9.08   Interest and penalties may be assessed by PHS on any overdue
            payments in accordance with the Federal Debt Collection Act. The
            payment of such late charges shall not prevent PHS from exercising
            any other rights it may have as a consequence of the lateness of
            any payment.

     9.09   All plans and reports required by this Article 9 and marked
            "confidential" by Licensee shall, to the extent permitted by law,
            be treated by PHS as commercial and financial information obtained
            from a person and as privileged and confidential, and any proposed
            disclosure of such records by the PHS under the Freedom of
            Information Act (FOIA), 5 U.S.C. Section 552 shall be subject to
            the predisclosure notification requirements of 45 CFR Section
            5.65(d).

10.  PERFORMANCE

     10.01  Licensee shall use its reasonable best efforts to bring the
            Licensed Products and Licensed Processes to Practical Application.
            "Reasonable best efforts" for the purposes of this provision shall
            include adherence to the Commercial Development Plan at Appendix F
            and performance of the Benchmarks at Appendix E. The efforts of a
            sublicensee shall be considered the efforts of Licensee.

     10.02  Upon the First Commercial Sale, until the expiration of this
            Agreement, Licensee shall use its reasonable best efforts to make
            Licensed Products and Licensed Processes reasonably accessible to
            the United States public.

11.  INFRINGEMENT AND PATENT ENFORCEMENT

     11.01  PHS and Licensee agree to notify each other promptly of each
            infringement or possible infringement of the Licensed Patent Rights
            and for Background Patent Rights, as well as any facts which may
            affect the validity, scope, or enforceability of the Licensed
            Patent Rights and/or Background Patent Rights of which either Party
            becomes aware.

     11.02  Pursuant to this Agreement and the provisions of Chapter 29 of
            title 35, United States Code, Licensee may: a) bring suit in its
            own name, at its own expense, and on its own behalf for
            infringement of presumably valid claims in the Licensed Patent
            Rights; b) in any such suit, enjoin infringement and collect for
            its use, damages, profits, and awards of whatever nature
            recoverable for such infringement; and c) settle any claim or suit
            for infringement of the Licensed Patent Rights provided, however,
            that PHS and appropriate Government authorities shall have the
            first right to take such actions. If Licensee desires to 


                                      14
<PAGE>


            initiate a suit for patent infringement, Licensee shall notify 
            PHS in writing. If PHS does not notify Licensee of its intent to 
            pursue legal action within ninety (90) days, Licensee will be 
            free to initiate suit. PHS shall have a continuing right to 
            intervene in such suit. Licensee shall take no action to compel 
            the Government either to initiate or to join in any such suit for 
            patent infringement. Licensee may request the Government to 
            initiate or join in any such suit if necessary to avoid dismissal 
            of the suit. Should the Government be made a party to any such 
            suit, Licensee shall reimburse the Government for any costs, 
            expenses, or fees which the Government incurs as a result of such 
            motion or other action, including any and all costs incurred by 
            the Government in opposing any such motion or other action. In 
            all cases, Licensee agrees to keep PHS reasonably appraised of 
            the status and progress of any litigation. Before Licensee 
            commences an infringement action, Licensee shall notify PHS and 
            give careful consideration to the views of PHS and to any 
            potential effects of the litigation on the public health in 
            deciding whether to bring suit.

     11.03  In the event that a declaratory judgment action alleging invalidity
            or non-infringement of any of the Licensed Patent Rights shall be
            brought against Licensee or raised by way of counterclaim or
            affirmative defense in an infringement suit brought by Licensee
            under Paragraph 11.02, pursuant to this Agreement and the
            provisions of Chapter 29 of Title 35, United States Code or other
            statutes, Licensee may: a) defend the suit in its own name, at its
            own expense, and on its own behalf for presumably valid claims in
            the Licensed Patent Rights; b) in any such suit, ultimately to
            enjoin infringement and to collect for its use, damages, profits,
            and awards of whatever nature recoverable for such infringement;
            and c) settle any claim or suit for declaratory judgment involving
            the Licensed Patent Rights- provided, however, that PHS and
            appropriate Government authorities shall have the first right to
            take such actions and shall have a continuing right to intervene in
            such suit. If PHS does not notify Licensee of its intent to respond
            to the legal action within a reasonable time, Licensee will be free
            to do so. Licensee shall take no action to compel the Government
            either to initiate or to join in any such declaratory judgment
            action. Licensee may request the Government to initiate or to join
            any such suit if necessary to avoid dismissal of the suit. Should
            the Government be made a party to any such suit by motion or ally
            other action of Licensee, Licensee shall reimburse the Government
            for any costs, expenses, or fees which the Government incurs as a
            result of such motion or other action. If Licensee elects not to
            defend against such declaratory judgment action, PHS, at its
            option, may do so at its own expense. In all cases, Licensee agrees
            to keep PHS reasonably appraised of the status and progress of any
            litigation. Before Licensee commences an infringement action,
            licensee shall notify PHS and give careful consideration to the
            views of PEIS and to any potential effects of the litigation on the
            public health in deciding whether to bring surf.

     11.04  In any action under Paragraphs 11.02 or 11.03, the expenses
            including costs, fees, attorney fees, and disbursements, shall be
            paid by Licensee. The value of any recovery made by Licensee
            through court judgment or settlement shall be treated as Net Sales
            and subject to earned royalties.

     11.05  PHS shall cooperate fully with Licensee in connection with any
            action under Paragraphs 11.02 or 11.03. PHS agrees promptly to
            provide access to all necessary documents and to render reasonable
            assistance in response to a request by licensee.

12.  NEGATION OF WARRANTIES AND LNDEMNIFICATION

     12.01  PHS offers no warranties other than those specified in Article 1.

     12.02  PHS does not wan ant the validity of the Licensed Patent Rights and
            Background Patent Rights and makes no representations whatsoever
            with regard to the scope of the Licensed Patent Rights and
            Background Patent Rights, or that the Licensed Patent Rights and
            Background Patent Rights may be exploited without infringing other
            patents or other intellectual proper rights of third parties.

     12.03  PHS MAKES NO WARRANTS, EXPRESSED OR IMPLIED, OF MERCHANTABILITY OR
            FITNESS FOR A PARTICULAR PURPOSE OF ANY SUBJECT MATTER DEFINED BY
            THE CLAIMS OF THE LICENSED PATENT RIGHTS AND BACKGROUND PATENT
            RIGHTS OR TANGIBLE MATERIALS RELATED THERETO.

     12.04  PHS does not represent that it will commence legal actions against
            third parties infringing the Licensed Patent Rights and/or
            Background Patent Rights.

     12.05  Licensee shall indemnify and hold PHS, its employees, students,
            fellows, agents, and consultants harmless from and against all
            liability, demands, damages, expenses, and losses, including but
            not limited to death, personal injury, illness, or property damage
            in connection with or arising out of: a) the use by or on behalf of
            Licensee, its sublicensees, directors, employees, or third parties
            of any Licensed Patent Rights and Background Patent Rights b) the
            design, manufacture, distribution, or use of any Licensed Products,
            Licensed Processes or materials by Licensee, or other products or
            processes developed in connection with or arising out of the
            Licensed Patent Rights and/or Background Patent Rights. Licensee
            agrees to maintain a liability insurance program consistent with
            sound business practice.

13.  TERM, TERMINATION, AND MODIFICATION OF RIGHTS

     13.01  This Agreement is effective when signed by all parties and shall
            extend to the expiration of the last to expire of the Licensed
            Patent Rights and Background Patent Rights unless sooner terminated
            as provided in this Article 13.

     13.02  In the event that Licensee is in default in the performance of any
            material obligations under this Agreement, including but not
            limited to the obligations listed in Article 13.05 and if the
            default has not been remedied within ninety (90) days after the
            date of notice in writing of such default, PHS may terminate this
            Agreement by written notice and pursue outstanding amounts owed
            through procedures provided by the Federal Debt Collection Act.

     13.03  In the Event that Licensee becomes insolvent, files a petition in
            bankruptcy, has such a petition filed against it, determines to
            file a petition in bankruptcy, or receives notice of a third
            party's intention to file an involuntary petition in bankruptcy,
            Licensee shall immediately notify PHS in writing. Furthermore, PHS
            shall have the right to terminate this Agreement immediately upon
            Licensee's receipt of written notice.

     13 .04 Licensee shall have a unilateral right to terminate this Agreement
            and/or any licenses in any country or territory by giving PHS sixty
            (60) days written notice to that effect.

     13.05  PHS shall specifically have the right to terminate or modify, at
            its option, this Agreement, if PHS determines that the Licensee: 1)
            is not executing the Commercial Development Plan submitted with its
            request for a license and the Licensee cannot otherwise demonstrate
            to PHS's satisfaction that the Licensee has taken, or can be
            expected to take within a reasonable time, effective steps to
            achieve Practical Application of the Licensed Products or Licensed
            Processes; 2) has not achieved the Benchmarks as may be modified
            under Paragraph 9.02; 3.) has not met one or more of the
            obligations of Appendix C; 4) has willfully made a false statement
            of, or willfully omitted, a material fact in the license
            application or in any report required by the license Agreement; 5)
            has committed a material breach of a covenant or agreement
            contained in the license; 6) is not keeping Licensed Products or
            Licensed Processes reasonably available to the public after
            commercial use commences; 7) cannot reasonably satisfy unmet health
            and safety needs; or 8) cannot reasonably justify a failure to
            comply with the domestic production requirement of Paragraph 5.02
            unless waived.  In making this determination, PHS will take into
            account the normal course of such commercial development programs
            conducted with sound and reasonable business practices and judgment
            and the annual reports submitted by Licensee under Paragraph 9.02.
            Prior to invoking this right, PHS shall give written notice to
            Licensee providing Licensee specific notice of, and a ninety (90)
            day opportunity to respond to, PHS's concerns as to the previous
            items 1) to 7). If Licensee fails to 


                                      17
<PAGE>


            alleviate PHS's concerns as to the previous items 1) to 7) or 
            fails to initiate corrective action to PHS's satisfaction, PHS 
            may terminate this Agreement.

     13.06  When the public health and safety so require, and after written
            notice to Licensee providing Licensee a sixty (60) day opportunity
            to respond, PHS shall have the right to require Licensee to grant
            sublicenses to responsible applicants, on reasonable terms, in any
            Licensed Fields of Use under the Licensed Patent Rights, unless
            Licensee can reasonably demonstrate that the granting of the
            sublicensee would not materially increase the availability to the
            public of the subject matter of the Licensed Patent Rights. PHS
            will not require the granting of a sublicensee unless the
            responsible applicant has first negotiated in good faith with
            Licensee.

     13.07  PHS reserves the right according to 35 U.S.C. Section 209(f)(4) to
            terminate or modify this Agreement if it is determined that such
            action is necessary to meet requirements for public use specified
            by federal regulations issued after the date of the license and
            such requirements are not reasonably satisfied by Licensee.

     13.08  Within thirty (30) days of receipt of written notice of PHS's
            unilateral decision to modify or terminate this Agreement, Licensee
            may, consistent with the provisions of 37 CFR 404.11, appeal the
            decision by written submission to the designated PHS official. The
            decision of the designated PHS official shall be the final agency
            decision. Licensee may thereafter exercise any and all
            administrative or judicial remedies that may be available.

     13.09  Within ninety (90) days of expiration or termination of this
            Agreement under this Article 13, a final report shall be submitted
            by Licensee. Any royalty payments, including those incurred but not
            yet paid (such as the full minimum annual royalty), and those
            related to patent expense, due to PHS shall become immediately due
            and payable upon termination or expiration. If terminated under
            this Article 13, sublicensees may elect to convert their
            sublicenses to direct licenses with PHS pursuant to Paragraph 4.03.
            Unless otherwise specifically provided for under this Agreement,
            upon termination or expiration of this Agreement, Licensee shall
            return all Licensed Products or other materials included within the
            Licensed Patent Rights and Background Patent Rights to PHS or
            provide PHS with certification of the destruction thereof

14.  GENERAL PROVISIONS

     14.01  Neither Party may waive or release any of its rights or interests
            in this Agreement except in writing. The failure of the Government
            to assert a right hereunder or to insist upon compliance with any
            term or condition of this Agreement shall not constitute a waiver
            of that right by the Government or excuse a similar subsequent
            failure to perform any such term or condition by Licensee.


                                      18
<PAGE>


     14.02  This Agreement constitutes the entire agreement between the Parties
            relating to the subject matter of the Licensed Patent Rights and
            Background Patent Rights, and all prior negotiations,
            representations, agreements, and understandings are merged into,
            extinguished by, and completely expressed by this Agreement.

     14.03  The provisions of this Agreement are severable, and in the event
            that any provision of this Agreement shall be determined to be
            invalid or unenforceable under any controlling body of law, such
            determination shall not in any way affect the validity or
            enforceability of the remaining provisions of this Agreement.

     14.04  If either Party desires a modification to this Agreement, the
            Parties shall, upon reasonable notice of the proposed modification
            by the Party desiring the change, confer in good faith to determine
            the desirability of such modification. No modification will be
            effective until a written amendment is signed by the signatories to
            this Agreement or their designees.

     14.05  The construction, validity, performance, and effect of this
            Agreement shall be governed by Federal law as applied by the
            Federal courts in the District of Columbia.

     14.06  All notices required or permitted by this Agreement shall be given
            by prepaid, first class, registered or certified mail or by an
            express/overnight delivery service provided by a commercial
            carrier, properly addressed to the other Party at the address
            designated on the following Signature Page, or to such other
            address as may be designated in writing by such other Party.
            Notices shall be considered timely if such notices are received on
            or before the established deadline date or sent on or before the
            deadline date as verifiable by U.S. Postal Service postman or dated
            receipt from a commercial carrier. Parties should request legibly
            dated U.S. Postal Service postmark or obtain a dated receipt from a
            commercial carrier or the U.S. Postal Service. Private metered
            postmarks shall not be acceptable as proof of timely mailing.

     14.07  This Agreement shall not be assigned by Licensee except: a) with
            the prior written consent of PHS, such consent not to be withheld
            unreasonably; or b) as part of a sale or transfer of substantially
            the entire business of Licensee relating to operations which
            concern this Agreement. Licensee shall notify PHS within ten (10)
            days of any assignment of this Agreement by Licensee, and Licensee
            shall pay PHS, as an additional royalty, one percent (1%) of the
            fair market value of any consideration received for any assignment
            of this Agreement within thirty (30) days of such assignment.

     14.08  Licensee agrees in its use of any PHS-supplied materials to comply
            with all applicable statutes, regulations, and guidelines,
            including PHS and DEBS regulations and guidelines. Licensee agrees
            not to use the materials for research involving human subjects or
            clinical trials in the United States without complying 


                                      19
<PAGE>


            with 21 CFR Part 50 and 45 CFR Part 46. Licensee agrees not to 
            use the materials for research involving human subjects or 
            clinical trials outside of the United States without notifying 
            PHS, in writing, of such research or trials and complying with 
            the applicable regulations of the appropriate national control 
            authorities. Written notification to PHS of research involving 
            human subjects or clinical trials outside of the United States 
            shall be given no later than sixty (60) days prior to 
            commencement of such research or trials.

     14.09  Licensee acknowledges that it is subject to and agrees to abide by
            the United States laws and regulations (including the Export
            Administration Act of 1979 and Arms Export Control Act) controlling
            the export of technical data, computer software, laboratory
            prototypes, biological material, and other commodities. The
            transfer of such items may require a license from the cognizant
            Agency of the U.S. Government or written assurances by Licensee
            that it shall not export such items to certain foreign countries
            without prior approval of such agency. PHS neither represents that
            a license is or is not required or that, if required, it shall be
            issued.

     14.10  Licensee agrees to mark the Licensed Products or their packaging
            sold in the United States with all applicable U.S. patent numbers
            and similarly to indicate "Patent Pending" status. All Licensed
            Products manufactured in, shipped to, or sold in other countries
            shall be marked in such a manner as to preserve PHS patent rights
            in such countries.

     14.11  By entering into this Agreement, PHS does not directly or
            indirectly endorse any product or service provided, or to be
            provided, by Licensee whether directly or indirectly related to
            this Agreement. Licensee shall not state or imply that this
            Agreement is an endorsement by the Government, PHS, any over
            Government organizational unit, or any Government employee.
            Additionally, Licensee shall not use the names of N1H, CDC, PHS, or
            DHHS or the Government or their employees in any advertising,
            promotional, or sales literature without the prior written consent
            of PHS.

     14.12  The Parties agree to attempt to settle amicably any controversy or
            claim arising under this Agreement or a breach of this Agreement,
            except for appeals of modifications or termination decisions
            provided for in Article 13 . Licensee agrees first to appeal any
            such unsettled claims or controversies to the designated PHS
            official, or designee, whose decision shall be considered the final
            agency decision. Thereafter, Licensee may exercise any
            administrative or judicial remedies that may be available.

     14.13  Nothing relating to the grant of a license, nor the grant itself,
            shall be construed to confer upon any person any immunity from or
            defenses under the antitrust laws or from a charge of patent
            misuse, and the acquisition and use of rights pursuant to 


                                      20
<PAGE>


            37 CFR Part 404 shall not be immunized from the operation of state 
            or Federal law by reason of the source of the grant.

     14.14  Paragraphs 4.03, 8.01, 9.05-9.07, 12.01-12.05, 13.08, 13.09, and
            14.12 of this Agreement shall survive termination of this
            Agreement.
