REGENERON PHARMACEUTICALS, INC.
Notes to Condensed Financial Statements

1.       Interim Financial Statements

         In the opinion of management of the Company, the accompanying unaudited
         interim financial statements reflect all adjustments, consisting only
         of normal recurring accruals, necessary to present fairly the Company's
         financial position as of June 30, 1997 and December 31, 1996 and the
         results of operations for the three months and six months ended June
         30, 1997 and 1996. The results of operations for such interim periods
         are not necessarily indicative of the results to be expected for the
         full year.

2.       Statement of Cash Flows

         Supplemental disclosure of noncash investing and financing activities:

         Capital lease obligations of approximately $619,000 and $775,000 were
         incurred during the first six months of 1997 and 1996, respectively,
         when the Company leased new equipment.

         Included in accounts payable and accrued expenses at June 30, 1997 were
         approximately $1,127,000 of capital expenditures and approximately
         $40,000 of costs incurred in connection with the Company's issuance of
         equity securities.

3.       Accounts Payable and Accrued Expenses

         Accounts payable and accrued expenses as of June 30, 1997 and 
         December 31, 1996 consist of the following:

                                                    June 30,    December 31,
                                                      1997         1996
                                                      ----         ----
                  Accounts payable                 $2,938,907   $2,178,308   
                  Accrued payroll and costs         1,006,600    1,047,812
                  Accrued clinical trial expense      319,500      319,500
                  Accrued expenses, other             410,280      389,062
                  Deferred compensation               401,463      422,463
                                                   ----------   ----------
                                                   $5,076,750   $4,357,145
                                                   ==========   ==========

4.       Collaboration Agreement

         In May 1997, the Company entered into a ten-year collaboration
agreement with The Procter & Gamble Company ("Procter & Gamble") to discover,
develop, and commercialize pharmaceutical products (the "P&G Agreement"), as
well as a securities purchase agreement and other related agreements. Procter &
Gamble agreed over the first five years of the various agreements to purchase up
to $60.0 million in Regeneron equity and provide up to $94.7 million in support

of Regeneron's research efforts related to the collaboration. In June 1997,
Procter & Gamble completed the purchase of 4.35 million shares of Regeneron
Common Stock at $9.87 per share for a total of $42.9 million and received five
year warrants to purchase an additional 1.45 million shares of Regeneron stock
at $9.87 per share. This purchase was in addition to a $10.0 

                                       6



million purchase of Regeneron Common Stock at $12.50 per share that was
completed in March 1997 pursuant to a December 1996 stock purchase agreement.
The P&G Agreement expanded and superceded a collaboration agreement that the
companies entered into in December 1996 jointly to develop drugs for skeletal
muscle injury and atrophy.

         In the second five years of the P&G Agreement, the companies will share
all research costs equally. Clinical testing and commercialization expenses for
jointly developed products will be shared equally throughout the ten years of
the collaboration. Procter & Gamble will have rights to Regeneron's current
technology (other than its work in the area of neurotrophic factors and
cytokines), which is expected to have application in cardiovascular, bone,
muscle, arthritis, and other disease areas. Procter & Gamble will also have
rights to new technology developed as a result of the collaboration. The
companies expect jointly to develop and market worldwide any products resulting
from the collaboration and share equally in profits. Either company may
terminate the P&G Agreement at the end of five years with at least one year's
prior notice or earlier in the event of default.

         Contract research and development revenue related to the P&G Agreement
and the December 1996 collaboration agreement was $0.9 million in the second
quarter of 1997 and $1.9 million for the first half of 1997. At June 30, 1997,
the Procter & Gamble contract research revenue receivable was $0.9 million.

5.       Impact of the Future Adoptions of Recently Issued Accounting Standards

         In February 1997, the Financial Accounting Standards Board issued
Financial Accounting Standard No. 128, "Earnings Per Share" ("SFAS 128"). SFAS
128 will require the Company to replace the current presentation of "primary"
per share data with "basic" and "diluted" per share data. Currently, outstanding
common stock equivalents are antidilutive and therefore management estimates
that the future adoption of SFAS 128 currently will not have a material impact
on the Company's per share data. SFAS 128 will be adopted by the Company for
periods ending after December 15, 1997.

         The Financial Accounting Standards Board issued Financial Accounting
Standard No. 130, "Reporting Comprehensive Income" ("SFAS 130") in June 1997.
Comprehensive Income represents the change in net assets of a business
enterprise as a result of nonowner transactions. Management does not believe
that the future adoption of SFAS 130 will have a material effect on the
Company's financial position and results of operations. The Company will adopt
SFAS 130 for the year ending December 31, 1998.

         Also in June 1997, the Financial Accounting Standards Board issued

Financial Accounting Standard No. 131, "Disclosures about Segments of an
Enterprise and Related Information" ("SFAS 131"). SFAS 131 requires that a
business enterprise report certain information about operating segments,
products and services, geographic areas of operation, and major customers in
complete sets of financial statements and in condensed financial statements for
interim periods. The Company is required to adopt this standard in 1998 and is
currently evaluating the impact of the standard.

involve risks and uncertainties relating to the future financial performance of
Regeneron Pharmaceuticals, Inc. ("Regeneron" or the "Company") and actual events
or results may differ materially. These statements concern, among other things,
the possible therapeutic applications of the Company's product candidates and
research programs, the timing and nature of the Company's clinical and research
programs now underway or planned, a variety of items described in the footnotes
to the Company's financial statements (including the useful life of assets, the
anticipated length of agreements, and other matters), and the future uses of
capital and financial needs of the Company. These statements are made by the
Company based on management's current beliefs and judgment. In evaluating such
statements, stockholders and investors should specifically consider the various
factors identified under the caption "Factors That May Affect Future Operating
Results" which could cause actual results to differ materially from those
indicated by such forward-looking statements.

         In May 1997, the Company entered into a ten-year collaboration
agreement with The Procter & Gamble Company ("Procter & Gamble") to discover,
develop, and commercialize pharmaceutical products (the "P&G Agreement"), as
well as a securities purchase agreement and other related agreements. Procter &
Gamble agreed, over the first five years of the various agreements, to purchase
up to $60.0 million in Regeneron equity and provide up to $94.7 million in
support of Regeneron's research efforts related to the collaboration. In June
1997, Procter & Gamble completed the purchase of 4.35 million shares of
Regeneron Common Stock at $9.87 per share for a total of $42.9 million and
received five year warrants to purchase an additional 1.45 million shares of
Regeneron stock at $9.87 per share. This purchase was in addition to a $10.0
million purchase of Regeneron Common Stock at $12.50 per share that was
completed in March 1997 pursuant to a December 1996 stock purchase agreement.
The P&G Agreement expanded and superceded a collaboration agreement that the
companies entered into in December 1996 jointly to develop drugs for skeletal
muscle injury and atrophy.

         During the second quarter of 1997, Amgen Inc. ("Amgen"), on behalf of
Amgen-Regeneron Partners, continued to conduct clinical trials of brain-derived
neurotrophic factor ("BDNF") for the treatment of amyotrophic lateral sclerosis 
("ALS," commonly known as Lou Gehrig's disease) via intrathecal delivery 

and of neurotrophin-3 ("NT-3") for the treatment of peripheral neuropathies
caused by diabetes. Amgen also continued to conduct a trial of BDNF in Europe
for the treatment of neuropathies caused by diabetes. The Company continued to
develop and manufacture BDNF for use by Sumitomo Pharmaceuticals Co., Ltd.
("Sumitomo Pharmaceuticals") in Japan.

         In January 1997, Amgen and Regeneron announced that the Phase III
clinical trial of BDNF delivered subcutaneously did not demonstrate clinical
efficacy in patients with ALS and that the trial confirmed the safety and
tolerability of BDNF seen in earlier trials. The failure of the Phase III trial
to achieve its primary end points had a materially adverse effect on the price
of the Company's Common Stock (which declined more than 50% immediately after
the announcement of the results of the trial). After the Phase III clinical
trial results were announced, the Company retained independent experts in the
fields of neurology and gastroenterology, as well as independent statisticians,
to conduct further examination of the data. This review by the Company and the
outside panels

                                       8



indicated 1) that a subset of ALS patients in the trial may have received a
benefit from BDNF treatment and 2) that BDNF appeared to have an effect on the
gastrointestinal system and might have a therapeutic role in treating
constipating conditions, among other disorders. The panels recommended, among
other things, that additional clinical and preclinical investigations of
subcutaneous BDNF for ALS and BDNF for gastrointestinal conditions should be
undertaken. The Company is reviewing these recommendations and the Phase III
data and is discussing with Amgen whether to undertake these or other
investigations of BDNF. Further development of BDNF in the United States must be
undertaken in accordance with the terms of the Company's collaboration agreement
with Amgen. Sumitomo Pharmaceuticals is currently planning to begin a Phase I
safety assessment of BDNF in 1997.

         The results of the Company's and its collaborators' past activities in
connection with the research and development of BDNF and NT-3 do not necessarily
predict the results or success of future activities including, but not limited
to, any additional preclinical or clinical studies of BDNF or NT-3. The Company
cannot predict whether, when, or under what conditions BDNF or NT-3 will be
shown to be safe or effective to treat any human condition or be approved for
marketing by any regulatory agency. The delay or failure of current or future
studies to demonstrate the safety or efficacy of BDNF or NT-3 to treat human
conditions or to be approved for marketing would have a material adverse impact
on the Company.

         Amgen continues to conduct a Phase I trial on behalf of Amgen-Regeneron
Partners of BDNF for ALS using intrathecal delivery. While intrathecal delivery
may be more successful in delivering BDNF to certain motor neurons (the nerve
cells that degenerate in ALS), it is not known whether intrathecal delivery will
prove any more successful in demonstrating safety and utility in patients with
ALS than the subcutaneous delivery used in the Phase III clinical trial that
failed to achieve its primary endpoints. If additional studies of BDNF for ALS
are undertaken, the time and expense required for such trials could be material

to the Company and the outcome will be uncertain. If subsequent trials are
conducted and such trials fail to demonstrate that BDNF is safe and effective in
the treatment of ALS, that failure could have a materially adverse effect on the
Company, the price of the Company's Common Stock, and the Company's ability to
raise additional capital.

         No assurance can be given that extended administration of NT-3 will be
safe or effective. The Phase I study of NT-3 in normal human volunteers that
concluded in 1995 was a short term (seven day) treatment study. The current NT-3
clinical study involves substantially longer treatment (six months or longer).
The treatment of peripheral neuropathy may present additional clinical trial
risks in light of the complex and not wholly understood mechanisms of action
that lead to the neuropathies, the presence of many other drugs to treat the
underlying conditions, the potential difficulty of achieving significant
clinical endpoints, and other factors. No assurance can be given that these or
any other studies of NT-3 will be successful or that NT-3 will be
commercialized.

         To date, Regeneron has not received any revenues from the commercial
sale of products and may never receive such revenues. Before such revenues can
be realized, the Company (or its collaborators) must overcome a number of
hurdles which include successfully completing its research and development
efforts and obtaining regulatory approval from the United States Food and Drug
Administration ("FDA") or regulatory authorities in other countries. In
addition, the biotechnology and pharmaceutical industries are rapidly evolving
and highly competitive, and new developments may render the Company's products
and technologies noncompetitive and obsolete.

                                       9



         In the absence of revenues from commercial product sales or other
sources (the amount, timing, nature, or source of which can not be predicted),
the Company's losses will continue as the Company conducts its research and
development activities. The Company's activities may expand over time and may
require additional resources, and the Company's operating losses may be
substantial over at least the next several years. The Company's losses may
fluctuate from quarter to quarter and will depend, among other factors, on the
timing of certain expenses and on the progress of the Company's research and
development efforts.

Results of Operations

         Three months ended June 30, 1997 and 1996. The Company's total revenue
increased to $6.6 million for the second quarter of 1997 from $6.2 million for
the same period in 1996. Contract research and development revenue decreased to
$4.4 million for the second quarter of 1997 from $4.6 million for the same
period in 1996. Contract research and development revenue earned from Sumitomo
Pharmaceuticals was $3.1 million for the second quarters of both 1997 and 1996,
representing $0.8 million for contract research and $2.3 million of
reimbursement for developing manufacturing processes for BDNF and supplying
BDNF. Contract research and development revenue earned from Amgen-Regeneron
Partners ("the Partnership") decreased to $0.4 million for the second quarter of

1997 from $1.5 million for the same period in 1996, as the Partnership conducted
less basic research on BDNF and NT-3. The Company entered into a research
collaboration agreement with Procter & Gamble in December 1996, which was
superceded by the P&G Agreement in May 1997. Contract research revenue related
to these agreements totaled $0.9 million for the second quarter 1997. Contract
manufacturing revenue related to the long-term manufacturing agreement (the
"Merck Agreement") with Merck & Co., Inc. ("Merck") for the second quarters of
1997 and 1996 totaled $0.9 million and $0.4 million, respectively. Investment
income in the second quarter of 1997 increased to $1.4 million from $1.1 million
for the same period in 1996, due primarily to higher levels of interest-bearing
investments resulting from the private placements of equity securities in 1996
and 1997 with Amgen, Medtronic, Inc. ("Medtronic"), and Procter & Gamble.

         The Company's total operating expenses decreased to $10.9 million in
the second quarter of 1997 from $13.8 million for the same period in 1996.
Research and development expenses were $6.9 million in the second quarter of
1997 and $6.8 million for the same period in 1996. Loss in Amgen-Regeneron
Partners decreased to $0.5 million in the second quarter of 1997 from $3.5
million for the same period in 1996 as the Partnership completed the Phase III
clinical trial of BDNF in 1996. Research and development expenses (including
Loss in Amgen-Regeneron Partners) were approximately 68% of total operating
expenses in the second quarter of 1997 compared to 75% for the same period in
1996.

         General and administrative expenses were $1.7 million in the second
quarter of 1997 and $1.6 million for the same period in 1996. Depreciation and
amortization expense decreased to $1.2 million in the second quarter of 1997
from $1.5 million in the second quarter of 1996 as certain laboratory equipment
became fully depreciated and capitalized patent costs were fully amortized in
1996. Interest expense was $0.2 million for the second quarters of both 1997 and
1996. Contract manufacturing expenses are direct expenses related to the
long-term manufacturing agreement with Merck. Such expenses, which are
reimbursed by Merck, increased to $0.5 million in the second quarter of 1997
from $0.1 million in the same period of 1996, primarily from increased equipment
validation costs.

                                       10



         The Company's net loss for the second quarter of 1997 was $4.3 million,
or $0.16 per share, compared to a net loss of $7.6 million, or $0.31 per share,
for the same period in 1996.

         Six months ended June 30, 1997 and 1996. The Company's total revenue
increased to $12.8 million for the six months ended June 30, 1997 from $11.3
million for the same period in 1996. Contract research and development revenue
for the six months ended June 30 decreased to $8.6 million in 1997 from $8.8
million in 1996. Contract research and development revenue for six months earned
from Sumitomo Pharmaceuticals was $5.9 million in 1997 and $5.8 million in 1996,
consisting of contract research revenue of $1.5 million in both periods and
reimbursement for developing manufacturing processes for BDNF and supplying BDNF
of $4.4 million in 1997 and $4.3 million in 1996. Contract research and
development revenue earned from Amgen-Regeneron Partners decreased to $0.8

million for the six months ended June 30, 1997 from $3.0 million for the same
period in 1996, as the Partnership conducted less basic research on BDNF and
NT-3. The Company entered into a research collaboration agreement with Procter &
Gamble in December 1996, superceded by the P&G Agreement in May 1997. Contract
research revenue related to these agreements totaled $1.9 million for the first
half of 1997. Contract manufacturing revenue related to the Merck Agreement for
the six months ended June 30, 1997 and 1996 totaled $1.6 million and $0.8
million, respectively. The increase represents reimbursement of increased costs
of equipment validation and personnel. Investment income in the first half of
1997 increased to $2.7 million from $1.7 million in the same period of 1996, due
primarily to higher levels of interest-bearing investments resulting from the
private placements of equity securities in 1996 and 1997 with Amgen, Medtronic,
and Procter & Gamble.

         The Company's total operating expenses decreased to $23.0 million in
the six months ended June 30, 1997 from $26.7 million for the same period in
1996. Research and development expenses increased to $14.0 million in the first
half of 1997 from $13.7 million for the same period in 1996. Loss in
Amgen-Regeneron Partners for the first six months of 1997 decreased to $2.2
million from $6.2 million for the same period in 1996, as the Partnership
completed the Phase III clinical trial of BDNF in 1996. Research and development
expenses for the six months ended June 30, 1997 and 1996 (including Loss in
Amgen-Regeneron Partners) represented approximately 70% and 74% of total
operating expenses, respectively.

         General and administrative expenses were $3.2 million and $3.1 million
in the first half of 1997 and 1996, respectively. Depreciation and amortization
expense decreased to $2.4 million in the first half of 1997 from $3.0 million in
the first half of 1996, as certain laboratory equipment became fully depreciated
and capitalized patent costs were fully amortized in 1996. Interest expense
decreased to $0.4 million for the six month period ended June 30, 1997 from $0.5
million in the comparable period in 1996, resulting from the expiration of
equipment leases during 1996. Contract manufacturing expenses are direct
expenses related to the long-term manufacturing agreement with Merck. Such
expenses, which are reimbursed by Merck, increased to $0.9 million in the first
half of 1997 from $0.2 million in the same period of 1996, primarily from
increased equipment validation costs.

         The Company's net loss for the six months ended June 30, 1997 was $10.2
million, or $0.38 per share, compared to a net loss of $15.4 million, or $0.66
per share, for the same period in 1996.

                                       11



Liquidity and Capital Resources

         Since its inception in 1988, the Company has financed its operations
primarily through private placements and public offerings of its equity
securities, revenue earned under the several agreements between the Company and
each of Amgen, Sumitomo Chemical Company, Ltd., Sumitomo Pharmaceuticals, Merck,
and Procter & Gamble and investment income. Procter & Gamble agreed over the
first five years of the P&G Agreement to purchase up to $60.0 million in

Regeneron equity and provide up to $94.7 million in support of Regeneron's
research efforts related to the collaboration. In June 1997, Procter & Gamble
completed the purchase of 4.35 million shares of Regeneron Common Stock at $9.87
per share for a total of $42.9 million and received five year warrants to
purchase an additional 1.45 million shares of Regeneron stock at $9.87 per
share. This purchase was in addition to a $10.0 million purchase of Regeneron
Common Stock at $12.50 per share that was completed in March 1997 pursuant to a
December 1996 stock purchase agreement. The P&G Agreement expanded and
superceded a collaboration agreement that the companies entered into in December
1996 jointly to develop drugs for skeletal muscle injury and atrophy. In
connection with the Company's agreement to collaborate with Sumitomo
Pharmaceuticals in the research and development of BDNF in Japan, Sumitomo
Pharmaceuticals paid the Company $22.0 million through December 1996 (which
includes a payment of $3.0 million for 1997) and agreed to pay the Company an
additional $3.0 million in 1998. Sumitomo Pharmaceuticals has the option to
cancel the 1998 payment; however, if such a cancellation were to occur, Sumitomo
Pharmaceutical's rights to develop and commercialize BDNF in Japan would revert
to the Company. In addition, the Company is being reimbursed in connection with
supplying Sumitomo Pharmaceuticals with BDNF for preclinical use.

         The Company's activities relating to BDNF and NT-3, as agreed upon by
Amgen and Regeneron, are being reimbursed by Amgen-Regeneron Partners, and the
Company recognizes such reimbursement as revenue. The funding of Amgen-Regeneron
Partners is through capital contributions from Amgen and Regeneron, who must
make equal payments in order to maintain equal ownership and equal sharing of
any profits or losses from the Partnership. The Company has made capital
contributions totaling approximately $42.6 million to Amgen-Regeneron Partners
from the Partnership's inception in June 1993 through June 30, 1997. The Company
expects that its capital contributions in 1997 will total approximately $3.0
million. These contributions could increase or decrease, depending upon the cost
of Amgen-Regeneron Partners' conducting additional BDNF and NT-3 preclinical and
clinical studies and the outcomes of those and other ongoing studies. Capital
contributions in future years are anticipated to be greater than in 1997.

         From its inception in January 1988 through June 30, 1997, the Company
invested approximately $55.5 million in property, plant, and equipment. This
includes $16.8 million to acquire and renovate the Rensselaer facility, $6.3
million of newly completed construction at the facility, and $7.6 million of
construction in progress related to the modification of the facility in
connection with the Merck Agreement. In connection with the purchase and
renovation of the Rensselaer facility, the Company obtained financing of $2.0
million from the New York State Urban Development Corporation, of which $1.8
million is outstanding. Under the terms of such financing, the Company is not
permitted to declare or pay dividends to its stockholders.

                                       12



         During 1996, the Company entered into a series of new leasing
agreements (the "New Lease Line") which provide up to $4.0 million to finance
equipment acquisitions and certain building improvements, as defined
(collectively, the "Equipment"). The Company may utilize the New Lease Line in
increments ("leases"). Lease terms are for four years after which the Company is

required to purchase the Equipment at defined amounts. Certain of the leases may
be renewed for eight months at defined monthly payments after which the Company
will own the Equipment. At June 30, 1997, the Company had available
approximately $0.5 million of the New Lease Line.

         The Company expects that expenses related to the filing, prosecution,
defense and enforcement of patent and other intellectual property claims will
continue to be substantial as a result of patent filings and prosecutions in the
United States and foreign countries. The Company is currently involved in two
interference proceedings in the Patent and Trademark Office between Regeneron's
patent applications and patents relating to CNTF issued to Synergen, Inc. Amgen
acquired all outstanding shares of Synergen in 1994.

         As of June 30, 1997, the Company had no established banking
arrangements through which it could obtain short-term financing or a line of
credit. Additional funds may be raised through, among other things, the issuance
of additional securities, other financing arrangements, and future collaboration
agreements. No assurance can be given that additional financing will be
available or, if available, that it will be available on acceptable terms.

         At June 30, 1997, the Company had $129.5 million in cash, cash
equivalents, and marketable securities. The Company expects to incur ongoing
funding requirements for capital contributions to Amgen-Regeneron Partners to
support the continued development and clinical trials of BDNF and NT-3. The
Company also expects to incur substantial funding requirements for, among other
things, its research and development activities (including preclinical and
clinical testing), validation of its manufacturing facilities, and the
acquisition of equipment, and may incur substantial funding requirements for
expenses related to the patent interference proceedings and other patent
matters. The amount needed to fund operations will also depend on other factors,
including the status of competitive products, the success of the Company's
research and development programs, the status of patents and other intellectual
property rights developments, and the continuation, extent, and success of any
collaborative research programs (including those with Amgen and Procter &
Gamble). The Company expects to incur additional capital expenditures in
connection with the renovation and validation of its Rensselaer facility
pursuant to its manufacturing agreement with Merck. However, the Company also
expects that such expenditures will be substantially reimbursed by Merck,
subject to certain conditions. The Company believes that its existing capital
resources will enable it to meet operating needs for at least the next several
years. No assurance can be given that there will be no change in projected
revenues or expenses that would lead to the Company's capital being consumed at
a faster rate than currently expected. In order to continue to attempt to assure
Regeneron's financial condition and maximize its technological developments for
the long-term benefit of shareholders, the Company from time to time seeks
additional corporate partners and explores other opportunities to obtain
research and development funding. No assurance can be given that such partners
or funding will be available or, if available, will be on terms favorable or
acceptable to the Company.

                                       13




Factors That May Affect Future Operating Results

         Regeneron cautions stockholders and investors that the following
important factors, among others, in some cases have affected, and in the future
could affect, Regeneron's actual results and could cause Regeneron's actual
results to differ materially from those expressed in any forward-looking
statements made by, or on behalf of, Regeneron. The statements under this
caption are intended to serve as cautionary statements within the meaning of the
Private Securities Litigation Reform Act of 1995. The following information is
not intended to limit in any way the characterization of other statements or
information under other captions as cautionary statements for such purpose:

o        Delay, difficulty, or failure of the Company's preclinical drug
         research and development programs to produce product candidates that
         are scientifically or commercially appropriate for further development
         by the Company or others.

o        Delay, difficulty, or failure in obtaining regulatory approval
         (including approval of its facilities for production) for the Company's
         products (including vaccine intermediate for Merck), including delays
         or difficulties in development because of insufficient proof of safety
         or efficacy.

o        Increased and irregular costs of development, regulatory approval,
         manufacture, sales, and marketing associated with the introduction of
         products in the late stage of development.

o        Cancellation or termination of material collaborative or licensing
         agreements (including in particular, but not limited to, those with
         Procter & Gamble and Amgen) and the resulting loss of research or other
         funding, could have a material adverse effect on the Company and its
         operations. A change of control of one or more of the Company's
         material collaborators or licensees could also have a material adverse
         effect on the Company.

o        Competitive or market factors may cause use of the Company's products
         to be limited or otherwise fail to achieve broad acceptance.

o        The ability to obtain, maintain, and prosecute intellectual property
         rights, and the cost of acquiring in-process technology and other
         intellectual property rights, either by license, collaboration, or
         purchase of another entity.

o        Difficulties or high costs of obtaining adequate financing to meet the
         Company's obligations under its collaboration and licensing agreements
         or to fund 50 percent of the cost of developing product candidates in
         order to retain 50 percent of the commercialization rights.

o        Amount and rate of growth in Regeneron's selling, general, and
         administrative expenses, and the impact of unusual or infrequent
         charges resulting from Regeneron's ongoing evaluation of its business
         strategies and organizational structure.

                                       14




o        Failure of corporate partners to commercialize successfully the
         Company's products or to retain and expand the markets served by the
         commercial collaborations; conflicts of interest, priorities, and
         commercial strategies which may arise between the Company and such
         corporate partners.

o        Difficulties in launching or marketing the Company's products by the
         Company or its licensees, especially when such products are novel
         products based on biotechnology, and unpredictability of customer
         acceptance of such products.

o        Inability to maintain or initiate third party arrangements which
         generate revenues, in the form of license fees, research and
         development support, royalties, and other payments, in return for
         rights to technology or products under development by the Company.

o        Delays or difficulties in developing and acquiring production
         technology and technical and managerial personnel to manufacture novel
         biotechnology products in commercial quantities at reasonable costs and
         in compliance with applicable quality assurance and environmental
         regulations and governmental permitting requirements.

o        Difficulties in obtaining key raw materials and supplies for the
         manufacture of the Company's product candidates.

o        The costs and other effects of legal and administrative cases and
         proceedings (whether civil, such as product-related or environmental,
         or criminal); settlements and investigations; developments or
         assertions by or against Regeneron relating to intellectual property
         rights and licenses; the issuance and use of patents and proprietary
         technology by Regeneron and its competitors, including the possible
         negative effect on the Company's ability to develop, manufacture, and
         sell its products in circumstances where it is unable to obtain
         licenses to patents which may be required for such products.

o        Underutilization of the Company's existing or new manufacturing
         facilities or of any facility expansions, resulting in inefficiencies
         and higher costs; start-up costs, inefficiencies, delays, and increased
         depreciation costs in connection with the start of production in new
         plants and expansions.

o        Health care reform, including reductions or changes in reimbursement
         available for prescription medications or other reforms.

o        The ability to attract and retain key personnel. As Regeneron's
         scientific efforts lead to potentially promising new directions, both
         outside of recombinant protein therapies (into orally active, small
         molecule pharmaceuticals) and outside of treatments for neurological
         and neurodegenerative conditions (into, for example, potential programs
         in cancer, inflammation, muscle disease, bone growth disorders,
         angiogenesis, and hemopoiesis), the Company will require additional

         internal expertise or external collaborations in areas in which it
         currently does not have substantial resources and personnel.

                                       15



Impact of the Adoption of Recently Issued Accounting Standards

         In February 1997, the Financial Accounting Standards Board issued
Financial Accounting Standard No. 128, "Earnings Per Share" ("SFAS 128"). SFAS
128 will require the Company to replace the current presentation of "primary"
per share data with "basic" and "diluted" per share data. Currently, outstanding
common stock equivalents are antidilutive and therefore management estimates
that the future adoption of SFAS 128 currently will not have a material impact
on the Company's per share data. SFAS 128 will be adopted by the Company for
periods ending after December 15, 1997.

         The Financial Accounting Standards Board issued Financial Accounting
Standard No. 130, "Reporting Comprehensive Income" ("SFAS 130") in June 1997.
Comprehensive Income represents the change in net assets of a business
enterprise as a result of nonowner transactions. Management does not believe
that the future adoption of SFAS 130 will have a material effect on the
Company's financial position and results of operations. The Company will adopt
SFAS 130 for the year ending December 31, 1998.

         Also in June 1997, the Financial Accounting Standards Board issued
Financial Accounting Standard No. 131, "Disclosures about Segments of an
Enterprise and Related Information" ("SFAS 131"). SFAS 131 requires that a
business enterprise report certain information about operating segments,
products and services, geographic areas of operation, and major customers in
complete sets of financial statements and in condensed financial statements for
interim periods. The Company is required to adopt this standard in 1998 and is
currently evaluating the impact of the standard.
