harbor" for forward- looking statements. Except for the historical information
contained herein, the matters discussed herein are forward-looking statements.

general economic and business conditions; fluctuations in the value of
securities for which only a limited, or no, public market exists; dependence on
the development of new technologies; dependence on timely development and
introduction of new and competitively priced products; the need for regulatory
approvals; the Sponsor Companies having insufficient funds to commercialize

                                     PART I

Item 1.  BUSINESS.

      PaineWebber R&D Partners III, L.P. (the "Partnership" or "Registrant") is
a Delaware limited partnership that commenced operations on June 3, 1991, with a
total of $43.1 million available for investment. Paine Webber Development
Corporation ("PWDC" or "General Partner"), an indirect, wholly-owned subsidiary
of Paine Webber Group Inc. ("PWG"), is the general partner and manager of the
Partnership. The principal objective of the Partnership is to provide long-term
capital appreciation to investors through investing in the development and
commercialization of new products (the "Projects") with technology and
biotechnology companies ("Sponsor Companies"), which are expected to address
significant market opportunities. The Partnership will terminate on December 31,
2015, unless its term is extended or reduced by the General Partner.

      The Partnership has completed the funding of its seven Projects at an
aggregate investment since inception of $32.5 million. As of December 31, 1997,
the Partnership had ongoing Projects with Alkermes, Inc., Cephalon, Inc. and
Gensia, Inc. The remaining Projects have either terminated or are near
termination. (See Exhibit B, the Annual Letter to the Limited Partners, for a
detailed discussion of the current status of the Partnership's active Projects.)
In addition to the investments in Projects, as of December 31, 1997, the
Partnership owned equity investments, warrants and marketable securities as
described in Notes 3 and 5 of the "Notes to the Financial Statements" included
in this filing on Form 10-K.

      At a meeting of the Board of Directors of PWDC in January 1997, the Policy
Regarding Requests for Partner Lists attached as Exhibit C was adopted.


PARTNERSHIP MANAGEMENT

      The Partnership has contracted with the General Partner, pursuant to a
management agreement (the "Management Contract"), responsibility for management
and administrative services necessary for the operation of the Partnership. An
Advisory Board, which has acted as special advisor to the General Partner, is
periodically provided with updates regarding the status of the Partnerhsip's
Projects (see Exhibit A for a brief biography of the current Advisory Board
members). All fees and expenses of the Advisory Board are paid for by the
General Partner.

      Under the Management Contract, the General Partner is entitled to receive
an annual management fee for management and administrative services provided to
the Partnership. As of January 1, 1997, the General Partner has eliminated
charging a management fee for services rendered to the Partnership.

and until cumulative profits and losses for each Unit equals Final Payout, 80%
to Limited Partners and 20% to the General Partner, and (iii) after Final

OTHER

      At December 31, 1997, the Partnership had no employees, and PWDC, the

ITEM 3.  LEGAL PROCEEDINGS.

In re:  PaineWebber Limited Partnership Litigation

      As previously disclosed on the Partnership's Form 10-K for the year ended
December 31, 1996, PWDC, the General Partner of the Partnership, was named as a
defendant in a class action lawsuit against PaineWebber Incorporated ("PWI") and
a number of its affiliates in the United States District Court for the Southern
District of New York (the "Court") relating to PWI's sale of approximately 50
direct investment offerings, including the offering of interests in the
Partnership. In January 1996, PWI signed a memorandum of understanding with the
plaintiffs in the class action outlining the terms under which the parties
agreed to settle the case. Under a settlement, PWI agreed to pay the class $125
million and certain additional consideration. The additional consideration
included the assignment of fees and income attributable to the general
partnership interest in the Partnership as well as guarantees of certain minimum
returns to class members. In March 1997, the Court approved the settlement as
fair and that order was affirmed by the United States Court of Appeals for the
Second Circuit in July 1997. Distribution of the settlement fund to the class
awaits the Court's determination of the amount of plaintiffs' counsel's fees and
disbursements to be awarded from the settlement fund.

      In February 1996, approximately 150 plaintiffs filed an action entitled
Abbate v. PaineWebber Inc. in Sacramento, California Superior Court against PWI
and various affiliated entities, including the General Partner of the
Partnership, concerning the plaintiffs' purchases of various limited partnership
interests. The complaint alleged, among other things, that PWI and its related
entities committed fraud and misrepresentation and breached fiduciary duties
allegedly owed to the plaintiffs by selling or promoting limited partnership
investments that were unsuitable for the plaintiffs and by overstating the
benefits, understating the risks and failing to state material facts concerning
the investments. The complaint sought compensatory damages of $15 million plus
punitive damages. In June 1996, additional complaints similar to the Abbate
action, but involving fewer plaintiffs, were filed in Sacramento, San Diego and
Arizona. In September 1996, the California Superior Court dismissed many of
Abbate plaintiffs' claims as barred by the applicable statutes of limitation.
Certain of the other complaints were also dismissed with prejudice while others
remained pending. In March 1997, all of these actions were settled. The
settlement had no effect on the Partnership or the General Partner.


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

         None.

                                     PART II

ITEM 5.     MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER 
            MATTERS.

      There is no existing public market for the Units, and no such market is
expected to develop. Units are transferable subject to certain restrictions as
set forth in the Partnership Agreement and applicable securities laws. As of
December 31, 1997, there were 4,732 Limited Partners.

      The Partnership distributes to the Partners, when available, the net
proceeds from royalty distributions, interest payments on portfolio securities
and net proceeds from dispositions of portfolio securities and any other cash in
excess of amounts that are necessary for the operation of the Partnership's
business. During the year ended December 31, 1997, the Partnership made cash
distributions to its Partners of $27,777,777 ($550 per Unit; $277,777 to the
general partnership interest). The Partnership made cash distributions to its
Partners of $24,895,837 ($493 per Unit; $245,837 to the general partnership
interest) and $5,050,505 ($100 per Unit; $50,505 to the general partnership
interest) for the years ended December 31, 1996 and 1995, respectively. In
addition, in 1995, the Partnership distributed to its Partners 202,261 warrants
of Alkermes, Inc. ("Alkermes") (4 warrants per Unit; 2,261 warrants to the
general partnership interest). The warrants were valued at $303,392 ($6 per
Unit; $3,392 to the general partnership interest) on the date of distribution.


ITEM 6.  SELECTED FINANCIAL DATA.

      See the "Selected Financial Data" on Page F-2 included in this filing on
Form 10-K.


ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS.

LIQUIDITY AND CAPITAL RESOURCES

      Partners' capital of $10.6 million at December 31, 1997, decreased by
$21.8 million from $32.4 million at December 31, 1996. For the year ended
December 31, 1997, the Partnership recognized net income of $5.9 million (as
discussed in Results of Operations below) which was offset by cash distributions
to the Partners in the amount of $27.7 million.

      The Partnership's funds are invested in marketable securities and a money
market fund until cash is needed to pay for the ongoing management and
administrative expenses of the Partnership or for distribution to the Partners.
Liquid assets at December 31, 1997, totaled $8.5 million, an increase of $7.6
million from the balance of $0.9 million at December 31, 1996. During 1997, the
restriction on the saleability of the Partnership's investment in common shares
of Biocompatibles International plc ("Biocompatibles") expired. The Partnership
reclassed this investment to marketable securities and recorded the shares at
December 31, 1997, at an aggregate market value of $6.6 million. In addition,
the Partnership received common shares of Gensia Sicor, Inc. ("Gensia") with a
market value at December 31, 1997, of $0.8 million. Also, during 1997, the
Partnership sold 1.285 million shares of Biocompatibles for proceeds of $28.0
million of which $27.7 million was distributed to the Partners. The balance of
the liquid assets at December 31, 1997, is to be used for the payment of
administrative costs related to managing the Partnership's business and future
distributions to the Partners.


RESULTS OF OPERATIONS

      Year ended December 31, 1997 compared to the year ended December 31, 1996:

      Net income for the years ended December 31, 1997 and 1996 was $5.9 million
and $39.5 million, respectively. The decrease of $33.6 million was a result of a
decrease in revenues of $34.5 million offset by a decrease in expenses of $0.9
million.

<PAGE>

(ITEM 7 CONTINUED)

      Revenues for the years ended December 31, 1997 and 1996 were $6.3 million
and $40.8 million, respectively. The decrease in revenues of $34.5 million is
due to a decrease in unrealized appreciation of marketable securities and
investments of $32.1 million and a decrease in gain on sale of product
development projects of $6.0 million (see Results of Operations for the year
ended December 31, 1996 as compared to the year ended December 31, 1995) offset
by an increase in realized gain on sale of marketable securities and investments
of $2.7 million and an increase in income from product development projects of
$0.9 million. Unrealized (depreciation) appreciation for the years ended
December 31, 1997 and 1996 was $(4.9) million and $27.2 million, respectively,
The Partnership recognized unrealized depreciation of $4.9 million during 1997
primarily from its investment in 0.815 million shares of Biocompatibles to
reflect a decrease in the market value from December 31, 1996 of $13.94 per
share to $8.124 per share at December 31, 1997. During 1996, in accordance with
Statement No. 115, the Partnership recorded its investment in 2.1 million
restricted shares of Biocompatibles at a market value of $29.3 million ($13.94
per share) as compared to its cost basis of $2.1 million. Accordingly, the
Partnership recognized unrealized appreciation of $27.2 million for the year
ended December 31, 1996. Realized gain on sale of marketable securities and
investments was $10.1 million for the year ended December 31, 1997, resulting
from the sale by the Partnership of 1.285 million shares of Biocompatibles with
an aggregate carrying value at December 31, 1996, of $17.9 million for proceeds
of $28.0 million. Realized gain on sale of marketable securities and investments
for the year ended December 31, 1996, was $7.4 million (see Results of
Operations for the year ended December 31, 1996 as compared to the year ended
December 31, 1995). During the year ended December 31, 1997, the Partnership
recognized income from product development projects of $0.9 million resulting
from its limited partnership investment in Gensia Clinical Partners, L.P.
("GCP"). During 1997 the Partnership received 0.13 million common shares of
Gensia with a market value on the date of distribution of $0.9 million as a
payment made pursuant to certain product agreements between Gensia Sicor, Inc.
and GCP.

      Expenses decreased from $1.3 million at December 31, 1996 to $0.4 million
at December 31, 1997, primarily as a result of the General Partner's decision to
discontinue charging a management fee to the Partnership.


      Year ended December 31, 1996 compared to the year ended December 31, 1995:

      Net income for the years ended December 31, 1996 and 1995 was $39.5
million and $5.3 million, respectively. The favorable variance of $34.2 million
resulted from an increase in revenues of $25.9 million and a decrease in
expenses of $8.3 million.

      Revenues increased from $14.9 million in 1995 to $40.8 million in 1996
resulting primarily from increases in (i) unrealized appreciation of investments
of $17.4 million, (ii) the gain from the sale of a product development project
of $6.0 million, and (iii) the gain on the sale of marketable securities and
investments of $3.0 million offset by a decrease on the gain upon distribution
of warrants of $0.3 million. Unrealized appreciation for the years ended
December 31, 1996 and 1995 was $27.2 million and $9.7 million, respectively. As
of December 31, 1996, in accordance with Statement No. 115, the Partnership
recorded its investment of 2.1 million restricted shares of Biocompatibles at
its market value of $29.3 million ($13.94 per share) as compared to its carrying
value of $2.1 million ($1.00 per share) at December 31, 1995 resulting in
unrealized appreciation of $27.2 million. At December 31, 1995, the
Partnership's investment of 0.65 million unrestricted shares of Biocompatibles
had a market value of $4.8 million ($7.375 per share) as compared to a carrying
value of $0.65 million ($1.00 per share). The Partnership's investment of 0.36
million shares of GelTex Pharmaceuticals, Inc. ("GelTex") had a market

<PAGE>

(ITEM 7 CONTINUED)

value of $4.4 million ($12.25 per share) and a carrying value of $1.0 million.
Accordingly, the Partnership recognized unrealized appreciation on its equity
investments in Biocompatibles and GelTex of $4.15 million and $3.4 million,
respectively. Also, as of December 31, 1995, the Partnership held exercisable
warrants to purchase common shares of Athena Neurosciences, Inc. ("Athena") and
Alkermes whereby the market value for each of the common shares as of this date
exceeded the exercise prices of the warrants. The Partnership recorded its
investments in these warrants at their intrinsic values (the excess of the
market price over the exercise price), and accordingly, recognized unrealized
appreciation of $2.1 million. In 1996, the Partnership sold its rights, title
and interest in its callable warrant to purchase 500,000 shares of Athena as
well as its various product program agreements with Athena for a purchase price
of $6.0 million and recognized a gain of this amount from the sale. The
Partnership recognized a gain from the sale of investments of $7.4 million and
$4.4 million for the years ended December 31, 1996 and 1995, respectively.
During 1996, the Partnership sold its investments of (i) 0.65 million shares of
Biocompatibles for proceeds of $5.3 million with a carrying value of $4.8
million resulting in a gain of $0.5 million; (ii) 0.36 million shares of GelTex
for proceeds of $6.8 million with a carrying value of $4.4 million resulting in
a gain of $2.4 million; (iii) 0.024 million shares of Alkermes for net proceeds
of $0.3 million with a carrying value of $0.2 million resulting in a gain of
$0.1 million; and (iv) 0.3 million shares of Elan Corporation, plc for proceeds 
of $8.3 million and a carrying value of $6.1 million resulting in a gain of $2.2
million. In addition, the Partnership sold its entitlement to Biocompatibles
Rights for total proceeds of $2.2 million and recognized a gain on the sale of
this amount. In October 1995, the Partnership sold 0.75 million shares of
Biocompatibles common stock at an aggregate sales price of $3.5 million and
recognized a gain upon the sale of $2.8 million. In November 1995, the
Partnership exercised its warrant to purchase 0.1 million shares of Cephalon,
Inc. common stock at an aggregate exercise price of $1.5 million and
simultaneously sold the shares at a selling price of $3.1 million, net of
commissions. Accordingly, the Partnership recognized a gain upon sale of $1.6
million. The Partnership distributed to its Partners in 1995 warrants to
purchase 0.2 million shares of Alkermes common stock. The exercise price of the
warrants was $1.0 million ($5.00 per share) compared to the market value of the
shares on the date of distribution of $1.3 million ($6.50 per share). The
Partnership recognized a gain upon distribution of $0.3 million.

      Expenses for the years ended December 31, 1996 and 1995 were $1.3 million
and $9.6 million, respectively. The decrease of $8.3 million resulted primarily
from decreases in (i) expenditures under Projects of $5.6 million; (ii)
write-down of an investment of $2.3 million and (iii) management fees of $0.3
million. Expenditures under Projects for the years ended December 31, 1996 and
1995 was $0.5 million and $6.1 million, respectively. In 1995, the Partnership
accrued expenditures under Projects in the amount of $3.2 million. Also, in
1995, the Partnership funded its final commitment to a Project in the amount of
$2.9 million. In 1995, GenPharm International, Inc. ("GenPharm") was
restructured resulting in a spin-off of its European subsidiary, Pharming BV. In
connection with the spin-off, the Partnership received 14,395 shares of Pharming
BV stock which the General Partner had valued at $1.2 million. In addition,
based on a review of the current and future financial prospects of GenPharm, the
General Partner had determined that the Partnership's investment in GenPharm's
convertible preferred stock, with a carrying value of $3.5 million, should be
valued at zero. Accordingly, the Partnership recognized a net write-down of its
GenPharm related investments in the amount of $2.3 million. Management fees were
further reduced in 1995 as a result of the General Partner's decision to
discontinue the management fee charged with respect to certain Projects.

YEAR 2000

      Like other financial and business organizations around the world, the
Partnership could be adversely affected if the computer systems utilized by the
Partnership and other service providers do not properly process and calculate
date-related information from and after January 1, 2000. This is commonly known
as the "Year 2000 Problem." The Partnership intends to work with its software
vendors to ensure that the Partnership's software is year 2000 compliant. The
Partnership does not expect the incremental expenses associated with the year
2000 and the potential disruption to operations to be significant.

Report of Independent Auditors


To the Partners of PaineWebber R&D Partners III, L.P.

We have audited the accompanying statements of financial condition of
PaineWebber R&D Partners III, L.P. as of December 31, 1997 and 1996, and the
related statements of operations, changes in partners' capital, and cash flows
for each of the three years in the period ended December 31, 1997. These
financial statements are the responsibility of the Partnership's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of PaineWebber R&D Partners III,
L.P. at December 31, 1997 and 1996, and the results of its operations and its
cash flows for each of the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles.

1.    ORGANIZATION AND BUSINESS

      PaineWebber R&D Partners III, L.P. (the "Partnership") is a Delaware
limited partnership that commenced operations on June 3, 1991. Paine Webber
Development Corporation ("PWDC" or the "General Partner"), an indirect,
wholly-owned subsidiary of Paine Webber Group Inc., is the general partner and
manager of the Partnership. The Partnership will terminate on December 15, 2015,
unless its term is extended or reduced by the General Partner.

      The principal objective of the Partnership has been to provide long-term
capital appreciation to investors through investing in the development and
commercialization of new products with technology and biotechnology companies
("Sponsor Companies"), which have been expected to address significant market
opportunities. The Partnership has been engaged in diverse product development
projects (the "Projects") including product development contracts, participation
in other partnerships and investments in securities of Sponsor Companies. Once
the product development phase has been completed, the Sponsor Companies have the
option to license and commercialize the products resulting from the product
development project, and the Partnership has the right to receive payments based
upon the sale of such products. The Partnership obtained warrants to purchase
the common stock of Sponsor Companies to provide additional capital appreciation
to the Partnership which was not directly dependent upon the outcome of the
Projects (see Note 5).

At December 31, 1997, the Partnership has made cash and security distributions,
as valued on the dates of distribution, since inception of $1,143 and $98 per
Unit, respectively.

      Profits and losses of the Partnership are allocated as follows: (i) until
cumulative profits and losses for each Unit equals Contribution Payout, 99% to
Limited Partners and 1% to the General Partner, (ii) after Contribution Payout
and until cumulative profits and losses for each unit equals Final Payout, 80%
to Limited Partners and 20% to the General Partner, and (iii) after Final
Payout, 75% to Limited Partners and 25% to the General Partner. As of December
31, 1997, the cumulative profits of the Partnership were $588 per Unit.

2.    SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      The financial statements are prepared in conformity with generally
accepted accounting principles which require management to make certain
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Such estimates and assumptions include the
carrying value of non-marketable securities. Actual results could differ from
those estimates.

      In accordance with the provisions of Statement of Financial Accounting
Standards No. 115, "Accounting for Certain Investments in Debt and Equity
Securities" ("Statement No. 115"), the Partnership accounts for its investments
in restricted common stock (where the restriction period expires in one year or
less) at market value with unrealized gains and losses reflected in the
Statements of Operations during the period in which the change in value occurs.
Investments in restricted common stock, whereby the restriction period exceeds
one year, are accounted for at the lower of cost or fair value.

      Marketable securities consist of a money market fund that is valued at
market value. Marketable securities are not considered cash equivalents for the
Statements of Cash Flows.

                          Notes to Financial Statements


(NOTE 2 CONTINUED)

      The Partnership's investments in stock of non-public companies are subject
to fluctuations in value dependent on the underlying value of the issuing
company. Non-publicly traded securities are valued at cost, except when a
decrease is required based on the General Partner's evaluations of the project
technology or Sponsor Company. These evaluations of value are made based on
currently available information and may not necessarily represent the amount, if
any, which may ultimately be realized.

      Realized and unrealized gains or losses are determined on a specific
identification method and are reflected in the Statements of Operations during
the period in which the change in value occurs.

      The General Partner incurred offering and organizational costs in the
amount of $1,813,138 and $125,724, respectively, that were reimbursed at the
Partnership's closings. Offering expenses have been charged against partners'
capital. Organizational costs incurred during the formation of the Partnership
were amortized over a period of 60 months from the date of the commencement of
operations.

      The Partnership invests in product development contracts with Sponsor
Companies either directly or through product development limited partnerships.
The Partnership expenses product development costs when incurred by the Sponsor
Companies and such costs are reflected as expenditures under product development
projects in the accompanying Statements of Operations. Income received and/or
accrued from investments in Projects is reflected in the Statements of
Operations for the period in which the income is earned.

      The Partnership carries warrants at a zero value in cases where the
Sponsor Company's stock is not publicly traded or the exercise period has not
been attained. To the extent that the Partnership's warrants are currently
exercisable and the Sponsor Company's stock is publicly traded, the warrants are
carried at intrinsic value (the excess of market price per share over the
exercise price per share), which approximates fair value.

Partnership recorded its investment of 2,100,000 restricted shares of
Biocompatibles at the market value of $13.94 per share as compared to a carrying
value of $1.00 per share. Accordingly, the Partnership recognized unrealized
appreciation of $27,173,754 for the year then ended. Upon expiration of the
restriction period in April 1997, the Partnership sold 1,285,000 Biocompatibles
shares and reclassed the remaining investment of 815,000 shares from Investments
to Marketable Securities. In 1996, the Partnership sold 650,000 shares of
Biocompatibles for proceeds of $5,291,129 (average price per share of $8.14).
The carrying value as of December 31, 1995 of the shares, including unrealized
appreciation of $4,143,750 for the year then ended, was $4,793,750 ($7.375 per
share). Accordingly, the Partnership recognized a realized gain of $497,379. In
1995, the Partnership sold 750,000 Biocompatibles shares for proceeds of
$3,537,782 as compared to a carrying value at December 31, 1994, of $750,000 and
recognized a realized gain of $2,787,782. In connection with a Rights Issue by

Partnership sold its entitlement to the rights at a price of (pound)2.20

      GenPharm International, Inc. ("GenPharm") is a biotechnology company which
is pursuing the research and development of transgenic technology for human
medical applications. In 1995, GenPharm's restructuring resulted in the spin-off
of its European subsidiary, Pharming BV. In connection with this spin-off, the
Partnership received 14,395 shares of Pharming BV Class A stock which the
General Partner valued at $1,150,000. Concurrently, the Partnership's investment
of 1,000,000 shares of GenPharm's convertible preferred stock was valued at zero
based on a review of the current and future financial prospects of GenPharm at
that time. Accordingly, the Partnership recognized a net write-down of its
GenPharm related investments of $2,350,000 for the year ended December 31, 1995.
Pursuant to an Agreement and Plan of Reorganization dated as of May 5, 1997,
GenPharm was acquired by Medarex, Inc. ("Medarex") whereby the outstanding
common and preferred stock of GenPharm was exchanged for Medarex common stock.
In October 1997, the Partnership received 281,708 common shares of Medarex in
exchange for its investment of 1,000,000 Series E convertible preferred shares.
The Medarex shares are not saleable until after December 31, 1998. The market
value of unrestricted Medarex common stock at December 31, 1997, was $5.25 per
share.

      PharmaGenics, Inc. ("PharmaGenics") is an integrated drug discovery
company engaged in the research and development of pharmaceuticals for the
treatment of cancer as well as other human diseases. The Partnership funded
$5,000,000 in connection with its Project with PharmaGenics which the
Partnership expensed in previous years. In 1995, the Partnership made a loan to
PharmaGenics in the amount of $1,000,000 which was subsequently converted into
480,242 shares of Series C Convertible Preferred Stock. In June 1997, the
Partnership exercised its option to exchange its rights, title and interests in
the various program agreements with PharmaGenics in return for 2,028,428
additional shares of PharmaGenics prefered stock. PharmaGenics preferred stock
was not publicly traded; therefore, no gain or loss was recognized on the
exchange. On June 18, 1997, the acquisition by Genzyme Corporation ("Genzyme")
of PharmaGenics to form Genzyme Molecular Oncology ("GMO") was completed. On
this date, the Partnership's total investment in PharmaGenics of 2,508,670
preferred shares was converted into 713,091 restricted common shares of GMO,
subject to certain adjustments. GMO common stock is not publicly traded;
therefore, the Partnership has recorded its investment in GMO stock at the
carrying value attributable to its investment in PharmaGenics preferred stock of
$1,000,000. Pursuant to the terms of the acquisition, the Partnership will be
entitled to sell its GMO stock approximately nine months following the
completion of an initial public offering by GMO.

      In 1996, the Partnership sold its investment of 357,233 common shares of
GelTex Pharmaceuticals Inc. for proceeds of $6,805,351 (average price per share

market value of $4,376,104 ($12.25 per share), including unrealized appreciation
recorded in 1995 of $3,376,104. Accordingly, the Partnership recognized a gain
of $2,429,247 for the year ended December 31, 1996. At December 31, 1995, the
Partnership held an exercisable warrant to purchase 500,000 common shares of
Athena Neurosciences, Inc. ("Athena") in which the market value of the common
shares of $12.25 per share exceeded the exercise price of $8.20 per share.

amount. As a result of a merger between Athena and Elan Corporation, plc
("Elan"), the Partnership's warrant to purchase Athena shares was converted into
a warrant to purchase 295,600 Elan shares. In 1996, the Partnership exercised
its Elan warrant at an aggregate exercise price of $4,099,972 ($13.87 per share)
and subsequently sold the shares for proceeds of $8,320,588 (average price per
share of $28.15). The Partnership recognized a gain of $2,195,616 upon the sale
for the year ended December 31, 1996.

4.    RELATED PARTY TRANSACTIONS

      The General Partner received an annual management fee for management and
administrative services provided to the Partnership. The management fee was
payable quarterly in advance and was adjusted annually on the first of each
fiscal year in an amount proportionate to the increase for the prior year in the
Consumer Price Index published by the United States Department of Labor. As of
January 1, 1997, the General Partner has eliminated the management fee charged
to the Partnership. The management fees paid by the Partnership to the General
Partner for the years ended December 31, 1996 and 1995, were $569,334 and
$857,658, respectively.

      The money market fund invested in by the Partnership is managed by an
affiliate of PaineWebber Incorporated ("PWI").

      PWDC and PWI, and its affiliates, have acted in an investment banking
capacity for several of the Sponsor Companies. In addition, PWDC and its
affiliates have direct limited partnership interests in some of the same product
development limited partnerships as the Partnership.

5.    PRODUCT DEVELOPMENT PROJECTS

      Of the Partnership's seven original Projects, the following three Projects
are currently active: a $6.0 million investment in Alkermes Clinical Partners,
L.P., a $46.0 million limited partnership formed to fund the development,
clinical testing, manufacturing and marketing of Receptor-Mediated
Permeabilizers for use in the treatment of diseases of the brain and central
nervous system by enabling the delivery of drugs across the blood brain barrier;
a $6.0 million investment in Cephalon Clinical Partners, L.P., a $45.0 million
limited partnership formed to fund the development, clinical testing,
manufacturing and marketing of Myotrophin(TM) for use in the treatment of
amyotrophic lateral sclerosis and certain other peripheral neuropathies; and a
$4.0 million investment in Gensia Clinical Partners, L.P., a $26.2 million
limited partnership formed to fund the development, clinical testing,
manufacturing and marketing of the GenESA(TM) System, a product designed to
enhance the diagnosis of heart disease.

      The remaining four Projects have been terminated or are near termination.
On April 18, 1996, Repligen Corporation ("Repligen") terminated its arrangements
with Repligen Clinical Partners, L.P. ("RCP") regarding the development and
marketing of RCP's recombinant platelet factor-4 ("rPF4") program in which the
Partnership funded $6.0 million. Repligen and RCP have agreed that the rights to
the rPF4 technologies will remain with RCP. The general partner of RCP is
seeking third parties who may be willing to either purchase or license the rPF4
technologies so that residual proceeds or royalties, if any, may be distributed
to the partners of RCP (including the Partnership). However, there can be no
assurance that a third party can be identified that is interested in purchasing
or licensing the rPF4 technologies or that there will be any residual proceeds
or royalties available for distribution.

                          Notes to Financial Statements


(NOTE 5 CONTINUED)

      On May 31, 1996, the Partnership sold, transferred and assigned its
rights, title, and interest in the callable warrant to purchase 500,000 shares
of Athena as well as its various program agreements with Athena for the
development of Diastat(R) for a purchase price of $6,000,000 and recognized a
gain of this amount from the sale of this product development project for the
year ended December 31, 1996.

      On June 2, 1997, the Partnership exchanged its interests in its various
program agreements with PharmaGenics in return for additional shares of
PharmaGenics preferred stock (see Note 3). The Partnership expects no returns
resulting from its Project with Cadre Technologies, Inc. for the development of
software tools for database applications.

      Pursuant to certain product agreements between GCP and Gensia, Gensia was
required to remit a milestone payment to GCP upon the approval of the
GenESA(TM)System by the U.S. Food and Drug Administration. Such approval was
received in September 1997 and, as part of the agreements, Gensia remitted
payment to GCP in shares of Gensia common stock. The Partnership, as a limited
partner in GCP, received 137,772 shares of Gensia with a market value on the
date of distribution of $6.80 per share and, accordingly, recognized income from
product development projects in the amount of $936,850 for the year ended
December 31, 1997 (see Note 3 - Marketable Securities).

      If the Projects produce any product for commercial sale, the Sponsor
Companies have the option to license the Partnership's technology to manufacture
and market the products developed. In addition, the Sponsor Companies have the
option to purchase the Partnership's interest in the technology. In
consideration for granting such purchase options, the Partnership has received
warrants to purchase shares of common stock of certain of the Sponsor Companies.
At December 31, 1997, the Partnership owned the following warrants:

                          Notes to Financial Statements


(NOTE 5 CONTINUED)

      Upon the exercise by the Partnership of its exchange option with
PharmaGenics in June 1997, the Partnership's warrant to purchase 1,000,000
shares of PharmaGenics at an exercise price of $2.15 per share was terminated.
In addition, the Partnership's purchase option warrant to purchase 666,667
PharmaGenics' shares was cancelled upon the closing of the acquisition of
PharmaGenics by Genzyme.

      On October 23, 1995, the Partnership distributed to its Partners a warrant
to purchase 202,261 shares of Alkermes common stock. The intrinsic value of the
warrant on the date of distribution was $303,392 ($1.50 per share) and,
accordingly, the Partnership recognized a gain of this amount. In November 1995,
the Partnership exercised its warrant to purchase 113,330 shares of Cephalon,
Inc. ("Cephalon") common stock at an aggregate exercise price of $1,536,128. The
shares were subsequently sold by the Partnership for total proceeds, net of
commissions, of $3,100,947 (average price per share of $27.362). Accordingly,
the Partnership recognized a gain of $1,564,819 for the year ended December 31,
1995.


6.    INCOME TAXES

      The Partnership is not subject to federal, state or local income taxes.
Accordingly, the individual partners are required to report their distributive
share of realized income or loss on their individual federal and state income
tax returns.


7.    SUBSEQUENT EVENT

      As of March 23, 1998, the market value of the Biocompatibles' shares had
decreased to approximately $2.2 million ($2.69 per share) from approximately
$6.6 million ($8.124 per share) as of December 31, 1997, resulting in unrealized
depreciation to the Partnership of approximately $4.4 million.

PAINEWEBBER R&D PARTNERS III, L.P.                            1997 ANNUAL REPORT
- --------------------------------------------------------------------------------

LETTER TO LIMITED PARTNERS

To Our Limited Partners:

PaineWebber R&D Partners III, L.P. (the "Partnership" or "R&D III") continued to
receive reports of significant developments from a number of sponsor companies
during 1997, including Alkermes, Inc. ("Alkermes"), Gensia Sicor, Inc.
("Gensia"), Cephalon, Inc. ("Cephalon") and certain other companies in which R&D
III has equity investments. In addition, R&D III made cash distributions
totaling $5,500 per $10,000 investment in the Partnership during the year.

R&D III was formed in 1991 and invested in a portfolio of seven product
development programs as well as four equity investments. The objective of each
investment is to obtain attractive returns for investors by accelerating the
development and commercialization of new products. In addition to cash
distributions derived from revenues of product sales in each product development
program, investors may benefit by the growth of the companies through the
issuance of warrants to purchase the companies' common stock. In each program,
the management team of PaineWebber Development Corporation has worked closely
with the sponsor companies to monitor the progress of each product development
program.

In addition to the product development programs in which the Partnership
invested, R&D III made four equity investments in privately-held companies, of
which three are active. R&D III invested $3.5 million in Biocompatibles
International plc ("Biocompatibles"), a U.K.-based development stage company
engaged in the research, development and commercialization of coatings which
reduce compatibility problems with certain medical devices. Biocompatibles
completed its initial public offering on the London Stock Exchange in 1995.
Through December 31, 1997, the Partnership distributed approximately $36.8
million from sales of 2.685 million shares of Biocompatibles common stock and
continues to hold 815,000 shares.

R&D III invested $3.5 million in Series E Convertible Preferred Stock of
GenPharm International, Inc. ("GenPharm"). In 1995, GenPharm completed a
restructuring by spinning-off its European subsidiary, Pharming BV, to its
shareholders. R&D III currently owns 14,395 shares of Pharming BV Class A stock.
In May 1997, GenPharm signed a definitive merger agreement with Medarex, Inc.
("Medarex") by which GenPharm shareholders would receive up to $65 million in
Medarex common stock. Upon the closing of the transaction in October 1997, the
Partnership received 281,708 shares and expects to receive additional Medarex
shares in late 1998 subject to the receipt of certain fees and payments relating
principally to the litigation brought against GenPharm by Cell Genesys, Inc. and
certain other matters.

R&D III invested $6 million, including a $1 million equity investment, in a
product development program using PharmaGenics Inc.'s ("PGI") proprietary
combinatorial chemistry procedure ("COMPILE") to discover novel therapeutics. In
February 1997, PGI signed a definitive agreement to be acquired by Genzyme
Corporation ("Genzyme") in a transaction valued at $28 million. The transaction
was approved by shareholders of PGI and Genzyme and in June 1997, R&D III
received 713,091 shares of Genzyme Molecular Oncology Inc. ("GMO"), a newly
formed private subsidiary of Genzyme.

During 1997, several of the sponsor companies of the Partnership's active
product development programs made significant announcements and attained certain
milestones. Alkermes completed its fourth Phase II clinical trial for RMP-7 and
the chemotherapeutic agent carboplatin in patients with recurrent, malignant
brain tumors and has commenced designing its Phase III study.

<PAGE>

Page 2

Alkermes also announced the signing of a joint development and commercialization
agreement with Alza Corp. valued at up to $60 million.

Earlier in the year, the U.S. Food and Drug Administration's ("FDA") Peripheral
and Central Nervous System Drug Advisory Committee did not recommend approval of
Cephalon's New Drug Application for its product Myotrophin(TM) used in the
treatment of amyotrophic lateral sclerosis ("ALS" or "Lou Gehrig's disease").
Cephalon is awaiting the final recommendation of the FDA, due before May 11,
1998.

Finally, in September, Gensia received marketing clearance from the FDA for the
GenESA(R) System which triggered a "milestone payment" of approximately 20% of
the aggregate capital contributions of limited partners of Gensia Clinical
Partners, L.P. in Gensia common stock. R&D III received 137,772 shares of Gensia
common stock. The Partnership intends to sell the common shares and distribute
cash at a future date. In October, Gensia commenced selling the GenESA System in
the U.S. market.

During 1997, R&D III made cash distributions to its limited partners totaling
$5,500 per $10,000 investment in the Partnership. The source of the
distributions was the sale of 1.285 million shares of Biocompatibles common
stock for proceeds of approximately $28 million. Total cash distributions since
the inception of the Partnership through December 31, 1997 are $11,430 per
$10,000 investment. The Partnership intends to continue to liquidate the
security positions it holds subject to market conditions and distribute the
proceeds to its limited partners.

In addition to potential returns from product development programs and equity
investments, R&D III has made three distributions of warrants, allowing
investors to purchase the common stock of certain sponsor companies at
predetermined prices. In October 1995, investors received a warrant to purchase
40 shares of Alkermes common stock per $10,000 investment in R&D III. The
Alkermes warrant is exercisable at a price of $5.00 per share through March 31,
2000. In January 1994, investors received a warrant to purchase 100 shares of
Cephalon common stock per $10,000 investment in R&D III. The Cephalon warrant
was exercisable at a price of $11.32 per share through August 31, 1997 and is
exercisable at a price of $13.82 per share from September 1, 1997 through August
31, 1999. In August 1993, investors received a warrant to purchase 60 shares of
Gensia common stock per $10,000 in R&D III. The Gensia warrant was exercisable
at a price of $17.47 per share through July 1996 and is currently exercisable at
$19.47 per share through July 1998. The value of all of the distributed warrants
has ranged from $980 based on the respective dates of distribution to $4,860 at
peak per $10,000 investment in R&D III.

Included in the Product Portfolio Status and Equity Investment sections are more
detailed discussions on the companies, status of the product development
programs and specific information concerning the securities associated with each
investment. Please refer to prior annual reports for information pertaining to
the Partnership's terminated or concluded investments with Athena Neurosciences,
Inc. and GelTex Pharmaceuticals, Inc.

Thank you for your continued interest in R&D III.

Sincerely,

Robin Stanley
Vice President

                            PRODUCT PORTFOLIO STATUS

ALKERMES, INC.

COMPANY

Alkermes, Inc. ("Alkermes") is developing innovative products based on
sophisticated drug delivery techniques for the treatment of central nervous
system disorders and for enhancing the effectiveness of existing
biopharmaceutical products. Alkermes' lead products are ProLease(R), Medisorb(R)
and RMP-7(TM) which focus on two drug delivery opportunities: (i) controlled,
sustained release of injectable drugs lasting several days to several weeks; and
(ii) the delivery of drugs into the brain past the blood-brain barrier.

PROGRAM

R&D III committed $6.0 million to Alkermes Clinical Partners, L.P., a $46.0
million limited partnership, formed to fund the development and human clinical
trials of receptor mediated permeabilizers ("RMPs"). Since June 30, 1996, the
research and development revenue from the partnership ended and Alkermes has
been using, and intends to continue to use, its own resources to continue to
develop RMP-7. During the year, Alkermes entered into a development and
commercialization agreement with Alza Corporation to accelerate and expand the
development of RMP-7. The agreement provides for Alkermes to receive up to $60
million, including a $10 million initial payment, over the course of the
agreement based upon attainment of certain milestones. The agreement further
provides that Alkermes will retain manufacturing responsibility and Alza will
have the option to acquire exclusive worldwide commercialization rights to
RMP-7. Alkermes has completed four Phase II clinical trials of RMP-7 and
carboplatin in patients with recurrent malignant brain tumors. The company is
currently designing its Phase III clinical study.

WARRANT

R&D III distributed the Alkermes warrant to the limited partners in October
1995. Investors received a warrant to purchase 40 shares of Alkermes common
stock per $10,000 investment in R&D III with an exercise price of $5.00 per
share through March 31, 2000. Based on the closing price of $6.50 per share on
the date of distribution, a warrant to purchase 40 shares of Alkermes common
stock had a value of approximately $60 per $10,000 unit. The available gain from
the distributed Alkermes warrant has ranged from $60 at distribution to $985 per
$10,000 investment in R&D III.

CAYENNE SOFTWARE, INC.

COMPANY

Cayenne Software, Inc. ("Cayenne") is a publicly traded company which supplies
modeling, database design and development solutions for commercial and technical
applications and database development. In July 1996, Cadre Technologies, Inc.
("Cadre") merged with Bachman Information Systems, Inc. to form Cayenne
Software, Inc. (NNM: CAYN).

<PAGE>

Page 2

PROGRAM

R&D III committed $1.5 million to Cadre's product development program which
funded the development of software tools for database applications. R&D III does
not expect any returns from this program.

WARRANT

In July 1996, Cadre warrants were converted into Cayenne warrants with the
Partnership owning a warrant to purchase 35,512 Cayenne common shares at an
exercise price of $25.91 per share through July, 1998. Warrants from this
transaction have not been distributed to investors. The common stock of Cayenne
closed at a price of $2.063 per share on December 31, 1997.


CEPHALON, INC.

COMPANY

Cephalon, Inc. ("Cephalon") discovers and develops pharmaceutical products for
the treatment of neurological disorders. The company focuses primarily on
neurodegenerative diseases, which are characterized by the death of neurons, the
specialized conducting cells of the nervous system. Cephalon's product
development programs are directed toward promoting neuronal survival using
neurotrophic factors and various classes of small molecules.

PROGRAM

R&D III committed $6.0 million to Cephalon Clinical Partners, L.P., a $45
million limited partnership formed to fund the development and human clinical
trials of Myotrophin(TM) for use in the treatment of amyotrophic lateral
sclerosis ("ALS" or "Lou Gehrig's disease") and certain peripheral neuropathies.
ALS is a fatal disorder of the nervous system characterized by the chronic,
progressive degeneration of motor neurons. Peripheral neuropathies refer to a
family of disorders of the peripheral nervous system characterized by a
degeneration of peripheral motor and sensory nerves. Myotrophin is a recombiant
form of an insulin-like growth factor, a naturally occurring neurotrophic factor
which is believed to participate in the nervous system's normal attempt to
recover from injury.

Earlier this year, the FDA's Peripheral and Central Nervous System Drugs
Advisory Committee ("the Panel") ruled that a Phase III study of Myotrophin
showed no significant evidence that the drug was effective. The Panel, citing
insufficient evidence on the matter of efficacy, voted to reject Cephalon's New
Drug Application ("NDA") based on the findings of two studies, the first
conducted in North America and the second in Europe. Cephalon has since
withdrawn and resubmitted the NDA after being informed by the Federal Drug
Administration that the Myotrophin NDA requires more in-depth analysis by the
agency before a final decision on the NDA can be made. The company anticipates
the FDA will reschedule the company's NDA for Myotrophin with a decision being
reached by May 11, 1998.

Also earlier in the year, Cephalon announced a joint development agreement with
Chiron Corporation for Myotrophin covering the North American and European
markets. In May, Cephalon and Chiron announced that they had filed a joint
Marketing Authorization Application for clearance to market Myotrophin in Europe
for the treatment of ALS. Currently, Myotrophin has been approved to be used
only as a Treatment Investigational New Drug ("IND") in which patients can
obtain the drug on a compassionate-use basis.
Cephalon has indicated that it will be

exploring the use of Myotrophin in treating post-polio syndrome,
demo-neuropathy, multiple sclerosis, diabetic neuropathy and certain other
neuromuscular disorders.

WARRANT

R&D III distributed the Cephalon warrant to limited partners in January 1994.
Investors received a warrant to purchase 100 shares of Cephalon common stock
(per $10,000 investment in R&D III) with an exercise price of $11.32 per share
through August 1997 and $13.82 per share from September 1997 through August
1999. Based on the closing price of $17.50 per share on the date of distribution
and the initial exercise price of $11.32 per share, a warrant to purchase 100
shares of Cephalon common stock had a value of approximately $618 per $10,000
unit. The available gain from the distributed Cephalon warrant has ranged from
$618 at distribution to $3,018 per $10,000 investment in R&D III.


GENSIA SICOR, INC.

COMPANY

Gensia Sicor, Inc. ("Gensia") is a vertically integrated pharmaceutical company
which focuses on the production of specialty bulk drug substances by synthesis
or fermentation, and the development, manufacturing and marketing of injectable
pharmaceuticals. The company has focused its product development efforts on the
worldwide oncology and injectable pharmaceutical markets.

During 1997, Gensia completed the sale of a majority interest in Gensia
Automedics, Inc. ("Gensia Automedics") to a private investor group led by Galen
Associates. As part of its corporate restructuring, Gensia had earlier
transferred its medical device assets, including the GenESA(R) System, to the
newly established subsidiary, Gensia Automedics. Also, Gensia created Metabasis
Therapeutics, Inc. ("Metabasis"), as a majority owned subsidiary, through which
its research efforts will be directed at discovering and developing small
molecule pharmaceuticals that are intended to target the treatment of pain,
diabetes (Type II) , inflammation and cardiovascular disease.

PROGRAM

R&D III committed $4.0 million to Gensia Clinical Partners, L.P. ("GCP"), a
$26.2 million limited partnership formed to fund the development and human
clinical trials of the GenESA System, a product designed to enhance the
diagnosis of cardiovascular disease. The GenESA System combines a drug,
arbutamine, and a computer-controlled drug administration system designed to
pharmacologically stress the heart. It is expected that this system will aid in
the diagnosis of patients who are suspected of having cardiovascular disease but
who are unable to undergo a traditional stress test due to an inability to
exercise adequately. Arbutamine is a drug developed to stimulate the heart
pharmacologically and thereby elicit certain cardiovascular responses similar to
those caused by exercise.

In September 1997, Gensia announced that it had received marketing clearance
from the FDA for the GenESA System for use in the diagnosis of coronary artery
disease in conjunction with radio-nuclide myocardial perfusion imaging and
echocardiography for patients who are unable to exercise adequately. Gensia
Automedics commenced U.S. marketing of the GenESA System in October, 1997. The
FDA approval of the GenESA System for marketing clearance triggered the
"milestone payment" to GCP, including R&D III. The "milestone payment"

<PAGE>

Page 4

was paid in Gensia common stock representing 20% of the initial capital
contributions. In October 1997, R&D III received 137,772 shares of Gensia common
stock, valued at $936,850 on the date of distribution.

WARRANT

R&D III distributed the Gensia warrant in August 1993. Investors received a
warrant to purchase 60 shares of Gensia common stock per $10,000 investment in
R&D III with an exercise price of $17.47 per share, which expired July 1996 and
$19.47 per share from August 1996 through July 1998. Based on the closing price
of $22.50 on the date of distribution and the initial exercise price of $17.47
per share, a warrant to purchase 60 shares of Gensia common stock had a value of
approximately $302 per $10,000 unit. The available gain from the distributed
Gensia warrant has ranged from $302 at distribution to $857 per $10,000
investment in R&D III.


REPLIGEN CORPORATION

COMPANY

Repligen Corporation ("Repligen") redirected its focus under new management in
1996 from the clinical development of biological products to the development of
enabling technology for the discovery of new drugs. The company's technology is
designed to increase the efficiency of the process by which new drug candidates
are identified. In 1996, Repligen announced to limited partners of Repligen
Clinical Partners, L.P. ("RCP"), including the Partnership, that the company had
terminated the research funding program with recombinant Platelet Factor-4
("rPF4"), the product being developed with funding from RCP. Repligen announced
in April 1996 that rPF4 had been evaluated in several clinical trials and showed
an excellent safety profile and potentially useful clinical activity.

PROGRAM

R&D III committed $6.0 million to RCP, a $45.0 million limited partnership
formed to fund the further clinical development of rPF4. rPF4 was being
developed to reverse the effects of heparin, a drug commonly used in patients
undergoing heart surgery and in other situations to prevent the formation of
blood clots. rPF4 may also retard the growth of solid tumors by inhibiting the
formation of new blood vessels necessary for tumors to grow.

Since the RCP funds have been depleted, Repligen has returned the rights to rPF4
to RCP in exchange for the termination of the research program. The Board of
Directors of the general partner of RCP is continuing to explore various
alternatives to maximize the value of the rPF4 technology to limited partners of
RCP.

WARRANTS

R&D III holds a warrant to purchase 385,700 shares of Repligen common stock, of
which 133,000 shares are exercisable at $2.50 per share and 252,700 are
exercisable at $3.50 per share. The warrant is exercisable through March 31,
2001. As of December 31, 1997, the closing price of Repligen common stock was
$0.781.

BIOCOMPATIBLES INTERNATIONAL PLC

Biocompatibles International plc ("Biocompatibles") is a U.K.-based, development
stage company engaged in the research, development and commercialization of
coatings and new materials which reduce compatibility problems associated with
certain medical devices including stents, catheters and coatings of certain
eye-care products. The company has indicated that it is seeking to form
strategic partnerships with one or two companies to provide the basis for the
commercialization of its products and technologies globally. Discussions with
Johnson & Johnson broke off earlier in the year regarding its stent products.
The company indicated that it was in discussions with a small group of companies
regarding partnering agreements, primarily covering the cardiovascular products.

R&D III invested $3.5 million in Biocompatibles convertible preferred stock in
1993 at a cost of $10.00 per share. The stock converted into ordinary shares
after the completion of the company's initial public offering on the London
Stock Exchange in April 1995 at a price of $2.67 per share. Simultaneously with
the company's initial public offering, the preferred stock held by R&D III
converted to common shares and split 10-for-1.

During 1997, R&D III sold 1,285,000 shares of Biocompatibles for proceeds of
$28,017,867. Cash distributions were made in May and August 1997 aggregating
$5,500 per $10,000 investment in the Partnership. The Partnership continues to
hold 815,000 shares of Biocompatibles. As of December 31, 1997, the closing
price of Biocompatibles shares was approximately $8.124 per share.*


GENZYME MOLECULAR ONCOLOGY

R&D III funded $5.0 million to a product development program utilizing
Pharmagenics Inc.'s ("PGI") proprietary combinatorial chemistry procedure
(COMPILE) to discover novel therapeutics and made an equity investment in the
amount of $1.0 million for 480,242 shares of PGI Series C Convertible Preferred
stock.

Early in 1997, PGI announced the signing of a definitive agreement to be
acquired by Genzyme Corporation ("Genzyme"). In June, shareholders of Genzyme
and PGI voted to approve the acquisition which was valued at approximately $28
million. The acquisition closed in June, with PGI shareholders receiving
approximately four million shares, or approximately forty percent of the initial
equity in the new division of a new Genzyme tracking stock, Genzyme Molecular
Oncology ("GMO"). GMO, a private company with its own common stock, develops
molecular approaches to cancer diagnosis and therapy through genomics, gene
therapy and a small-molecule combinatorial chemistry drug discovery program.

In June, R&D III's PGI shares were converted into 713,091 restricted common
shares of GMO, 127,264 shares attributable to its equity investment and 585,827
shares attributable to the "buyout" of the development program. It is
anticipated that PGI shareholders, including R&D III, will receive their GMO
common shares within six to nine months following the completion of an initial
public offering of GMO.



*    As of March 23, 1998, the closing price of Biocompatibles shares was
     approximately $2.69 per share.

MEDAREX, INC.

R&D III purchased $3.5 million of GenPharm International Inc. ("GenPharm")
Series E Convertible Preferred Stock. In 1995, GenPharm completed a
restructuring of the company resulting in the spin off of its European
subsidiary, Pharming BV. As a part of the company's restructuring, R&D III
received 14,395 shares of Pharming BV Class A stock. Pharming BV, a private
company, is principally engaged in the development of proprietary technology for
the production of human health care proteins in the mammary glands of transgenic
animals.

In May, GenPharm announced the signing of a definitive merger agreement with
Medarex, Inc. ("Medarex") by which holders of GenPharm stock would receive up to
$65 million in Medarex common stock. The shareholders of GenPharm, including R&D
III, and Medarex approved the merger agreement and the transaction closed in
October. R&D received 281,708 shares of Medarex common stock, which are the
subject of a lock-up agreement which extends through December 31, 1998. As
provided for in the merger agreement, GenPharm shareholders expect to receive
additional Medarex shares in late 1998 subject to the receipt of certain fees
and payments due from third parties in connection with the litigation brought
against GenPharm by Cell Genesys, Inc. and other matters.

Medarex is a biopharmaceutical company developing antibody-based therapeutics.
The company employs several core technologies including bispecific antibodies
which enhance and direct the body's own immune system to fight disease, the
HuMAb-Mouse antibody development system for the creation of high affinity human
antibodies, and immunotoxin technology. Medarex has five products in clinical
development including the anti-cancer Bispecifics MDX-210 and MDX-447, MDX-33
for autoimmune diseases, MDX-RA for the prevention of secondary cataracts, and
MDX-22 for acute myeloid leukemia.




EXHIBIT C              PAINEWEBBER R&D PARTNERS III, L.P.
                        (a Delaware Limited Partnership)

                  Policy Regarding Requests for Partner Lists


      In accordance with the provisions of the Delaware Revised Uniform Limited
Partnership Act (the "Act"), and without limiting its rights under the
Partnership Agreement or the Act, as each may be amended from time to time, the
General Partner of the Partnership has established standards applicable to
requests for lists of Limited Partners. These standards have been established in
order to assure (1) that the lists are not used for an improper or inappropriate
purpose or in any way that might be detrimental to the Partnership or the
Limited Partners; (2) that the Limited Partners have sufficient information and
opportunity to decide how they should react in response to any solicitation or
other communication addressed to them; and (3) that the Partnership and the
Limited Partners do not face an increased risk of adverse tax consequences as a
direct or indirect result of any such solicitation or communication.

      The General Partner requires any request to be made in writing by a record
holder of limited partner interests with standing to request the list, to comply
strictly with all applicable requirements of law and the Partnership Agreement,
to state the purpose for which the request is made with sufficient specificity
to enable the General Partner to make the determinations specified above, and to
include an undertaking under oath by the person requesting the list and the
persons or entities on whose behalf it is requested (1) to hold the list in
strict confidence, and not to give any information derived from the list to any
third party for any purpose whatsoever, (2) to reimburse the Partnership for
costs incurred in connection with the request and for a list, including
confirming compliance with the undertakings required hereby and (3) to submit to
the jurisdiction of the courts of the State of Delaware in any dispute arising
in connection with such request and to appoint and maintain RL&F Service Corp.,
One Rodney Square, Tenth Floor, Wilmington, New Castle County, Delaware 19801
(whose reasonable fees and expenses will be paid by the Partnership) as such
person's or entity's agent in the State of Delaware for acceptance of legal
process in connection therewith. In addition, in the case of requests made for
the purpose of soliciting tenders of the Limited Partners' interests or units in
the Partnership or soliciting proxies or consents from Limited Partners or
facilitating, assisting or supporting any such solicitation, the General Partner
will, if and to the extent required by applicable law and the Partnership
Agreement, make lists available or agree to disseminate such solicitations on
behalf of requesting Limited Partners only upon receipt of an undertaking under
oath by the person requesting the list and the persons or entities on whose
behalf it is requested (1) to conduct the solicitation in accordance with the
requirements of the Securities and Exchange Act of 1934 and the rules of the
Securities and Exchange Commission thereunder, including full disclosure of all
material facts and, in the case of any tender offer, rights of proration and
withdrawal rights, irrespective of the number of interests or units sought, and
(2) to refrain from acquiring interests or units of any number if the General
Partners, based upon advice from counsel, conclude that such acquisition would
increase the risk of adverse tax consequences to the Partnership or the
Partners.

      The General Partner shall endeavor to inform the requesting party within
30 days of receipt of the requisite undertakings whether they consider that the
proposed use of the list is improper or inappropriate or would increase the risk
of such adverse tax consequences, and may request such further assurances as may
be necessary in order to enable them to make any of the determinations specified
above.
