PROXY STATEMENT
FOR THE SPECIAL MEETING OF LIMITED PARTNERS
TO BE HELD ON [________], 2000
-----------------------
This proxy statement and the enclosed proxy are being mailed to the
limited partners of Repligen Clinical Partners, L.P., a Delaware limited
partnership, on or about [ ], 2000 by Repligen Development Corporation, a
wholly-owned subsidiary of Repligen Corporation, on behalf of the partnership
to solicit proxies for use at a special meeting to be held on [ ], 2000 at [
], local time, at [ ].
The purpose of the special meeting is to consider and vote upon the
proposal to terminate Repligen Partners following the unsuccessful efforts of
Repligen Partners and Repligen Corporation to identify a purchaser for the
assets of Repligen Partners. If the termination is approved and certain other
conditions met, Repligen Partners will be terminated, liquidated and
dissolved. Any liquidating distribution to limited partners will be based on
any remaining cash of Repligen Partners after paying or providing for payment
of Repligen Partners' actual costs incurred and accrued through the effective
time of the termination, including reasonable reserves, in connection with:
(i) the proxy solicitation; and (ii) the winding up of Repligen Partners,
including preparation of the final audit, tax return and K-1s, and all other
outstanding partnership liabilities. As the remaining non-cash assets of
Repligen Partners will be abandoned by the Board of Directors of Repligen
Development prior to the termination, Repligen Development does not expect
there to be any amounts available for distribution to the limited partners.
Repligen Development will not receive any fees from Repligen Partners in
connection with the termination and liquidation.
For a detailed description of the proposed termination, including the
subsequent liquidation, see "Termination and Dissolution of the Partnership".
Repligen Development has determined the proposed termination to be in the
best interests of Repligen Partners and its limited partners, has approved and
declared advisable the termination and recommends that the limited partners
vote for approval of the termination. See "The Proposed
Termination--Recommendation of Repligen Development; Reasons for the Proposed
Termination".
Under the limited partnership agreement dated as of January 9, 1992 among
Repligen Development, the purchasers of Class A units and the purchaser of
Class B units, approval of the termination requires the affirmative vote of
the holders of at least 66 2/3% of the outstanding limited partnership
interests (based on adjusted capital contributions). Accordingly, the
termination will not be approved unless the holders of 66 2/3% of the
outstanding limited partnership interests vote in its favor. Thus, failure to
submit a proxy or to vote in person at the special meeting or abstention by
you will have the same effect as a vote against the termination.
In reviewing this proxy statement, you should carefully consider the
matters described under "Risk Factors" on page [ ].
No person has been authorized to give any information or to make any
representation not contained in this proxy statement, and, if given or made,
such information or representation should not be relied upon as having been
authorized. The delivery of this proxy statement shall not under any
circumstances create any implication that there has been no change in the
affairs of Repligen Partners since the date as of which information is
furnished or the date hereof.
The proposed termination has not been approved or disapproved by the
Securities and Exchange Commission or any state securities commission. Neither
the Securities and Exchange Commission nor any
<PAGE>
state securities commission has passed upon the fairness or merits of the
proposed transaction nor upon the accuracy or adequacy of the information
contained in this proxy statement. Any representation to the contrary is a
criminal offense.
The date of this proxy statement is [ ], 2000

AVAILABLE INFORMATION
Repligen Partners is subject to the informational requirements of the
Securities and Exchange Act of 1934, as amended, and filed annual reports on
Form 10-K for the fiscal years ended December 31, 1996, 1995 and 1994, and
quarterly reports on Form 10-Q for the fiscal quarters ended (i) March 31,
1995, 1994, 1993 and 1992, (ii) June 30, 1995, 1994, 1993 and 1992 and (iii)
September 30, 1995, 1994, 1993 and 1992 and other information with the SEC.
The foregoing reports and other information filed by Repligen Partners with
the SEC can be inspected and copied at the public reference facilities
maintained by the SEC at Room 1024, 450 Fifth Street, N.W., Washington D.C.
20549 and should be available at the SEC's Regional Offices in New York (7
World Trade Center, 13th Floor, New York, New York 10048), Los Angeles (Suite
500 East, Tishman Building, 5757 Wilshire Boulevard, Los Angeles, California
90036) and Chicago (500 West Madison Avenue, Suite 1400, Chicago, Illinois
60661). Copies of this material can also be obtained from the Public Reference
Section of the SEC at 450 Fifth Street, N.W., Washington, D.C. 20549, at
prescribed rates. In light of the significant reduction in Repligen Partners'
capital resources, see "The Proposed Termination--The Partnership--Subsequent
Developments" and "Selected Financial Information--Management's Discussion and
Analysis of Financial Condition and Results of Operations", and the
corresponding need to conserve Repligen Partners' remaining cash and other
liquid assets, on April 29, 1996 the board of directors resolved to partially
suspend indefinitely compliance with such informational requirements due to
the costs of legal and accounting services associated therewith. As a result,
Repligen Partners has not filed any quarterly reports on Form 10-Q or any
reports on Form 8-K since 1995. The financial information contained in this
proxy statement, however, includes substantially all for the information that
would have been contained in the quarterly report for the quarter ended
September 30, 1999 had such quarterly report been filed by Repligen Partners.

SUMMARY AND SPECIAL FACTORS
The following is a summary of some of the information contained elsewhere
in this proxy statement. This summary is not intended to be complete and is
qualified in its entirety by the more detailed information contained in this
proxy statement. You are urged to read this proxy statement in its entirety
and to consider it with care.
This proxy statement contains forward-looking statements. Such statements
are subject to a number of risks and uncertainties. Actual results in the
future could differ materially from those described in the forward-looking
statements as a result of the factors in this proxy statement generally.
Repligen Partners further cautions you that the discussion of these factors
may not be exhaustive. Repligen Partners undertakes no obligation to publicly
release the result of any revisions to these forward-looking statements that
may be made to reflect any future events or circumstances.
The Parties
Repligen Clinical Partners, L.P., 117 Fourth Avenue, Needham, MA 02194.
Telephone: (800) 742-4744.
Repligen Corporation, 117 Fourth Avenue, Needham, MA 02194. Telephone:
(781) 495-9560.
The Proposed Termination
Pursuant to the terms of the limited partnership agreement, Repligen
Partners proposes to terminate, liquidate and dissolve Repligen Partners.
Termination and Dissolution of the Partnership
If the termination is approved and consummated, Repligen Partners will be
terminated pursuant to the terms of the limited partnership agreement, and
will be liquidated and dissolved. Promptly thereafter, each limited partner
will receive a liquidating distribution based upon any remaining cash of
Repligen Partners after paying or providing for payment of the transaction
costs and other outstanding partnership liabilities. Repligen Development does
not expect there to be any amounts available for distribution to the limited
partners. See "Termination and Dissolution of Repligen Partners". Repligen
Development will not receive any fees from Repligen Partners in connection
with the termination.
Recommendation of Repligen Development; Reasons for the Proposed Termination
Repligen Development recommends that the limited partners vote for
approval of the termination. After considering Repligen Partners' financial
condition and prospects, the availability and effect of other alternatives and
the factors discussed below, the board of directors of Repligen Development
has unanimously:
o determined the proposed termination and resulting liquidation to be in
the best interests of Repligen Partners and its limited partners;
o approved and declared advisable the termination, subject to approval
by the limited partners, followed by the liquidation; and
o recommends that the limited partners vote for approval of the
termination.
2
<PAGE>
Vote Required to Approve the Termination
Under the limited partnership agreement, approval of the termination
requires the affirmative vote of the holders of at least 66 2/3% of the
outstanding limited partnership interests (based on adjusted capital
contributions). Accordingly, the termination will not be approved unless the
limited holders of 66 2/3% of the outstanding limited partnership interests
vote in its favor. Thus, the failure to submit a proxy card (or to vote in
person at the special meeting) or the abstention from voting by a limited
partner will have the same effect as a vote against the termination.
Certain Federal Income Tax Considerations
[This summary outlines certain Federal income tax principles applicable
to limited partners in connection with the liquidation. This summary deals
only with the treatment of a limited partner who acquired his interest for
cash pursuant to the February 28, 1992 private offering. There are numerous
other Federal income tax principles not discussed herein that may be important
to a limited partner in connection with Repligen Partners. Each limited
partner is urged to consult his own tax advisor concerning his investment in
Repligen Partners and the possible tax consequences of the liquidation.
Each limited partner will recognize a net loss in connection with the
liquidation equal his adjusted basis in his limited partnership interest.
Repligen Partners intends to take the position that it incurs an ordinary
loss in connection with the liquidation, a distributive share of which is
allocated in turn to each limited partner. The Internal Revenue Service,
however, may seek to disallow any such ordinary loss and to characterize each
limited partner's loss as a capital loss, the deductibility of which would be
subject to limitations.]

RISK FACTORS
You should consider the following matters in considering whether to vote
in favor of the termination of Repligen Partners. These matters should be
considered in conjunction with the other information included in this proxy
statement.
Loss of opportunity to benefit from future events
It is possible that the future performance of recombinant platelet factor
- -4, or rPF4, will improve or that a buyer may be prepared to purchase Repligen
Partners or Repligen Partners' assets at some point in the future. It is also
possible that Repligen Corporation may be required to pay Repligen Partners
royalties on competitive products in the future or that the limited partners
might otherwise earn a higher return on their investment if Repligen Partners
remained in existence.
The possibility that there may be a buyer for the rPF4 technology
Although Repligen Development considers its efforts to market Repligen
Partners' assets to have been exhaustive, it is possible that additional
marketing efforts may have resulted in a purchaser for Repligen Partners'
assets being identified. The marketing activities undertaken by Repligen
Development are described below under "The Proposed Termination - Background
of the Proposed Termination".
Conflicts of Interest
The recommendation of Repligen Development could be deemed to involve
certain conflicts of interest between Repligen Development and the limited
partners, as Repligen Development is a wholly-owned subsidiary of Repligen
Corporation. Theodore Maione, the current President of Repligen Development,
is a former employee of Repligen Corporation and is receiving financial
compensation from PaineWebber to manage the assets, marketing effort and
termination and liquidation activities of Repligen Partners.
PaineWebber, an investment bank, marketed the private placement of
limited partnership interests in Repligen Partners and has been involved in
the marketing of similar financing vehicles. In addition to being a limited
partner in Repligen Partners, PaineWebber representatives currently constitute
two out of the three remaining directors on Repligen Development's board of
directors.

GENERAL INFORMATION
This proxy statement and enclosed proxy are being mailed to the limited
partners in connection with the solicitation of proxies by and on behalf of
Repligen Development for use at the special meeting to be held on [
], 2000 at [time], local time, at [location], and any adjournment or
postponement thereof. This proxy statement is being mailed to the limited
partners on or about [ ], 2000.
Purpose of Special Meeting
The purpose of the special meeting will be to consider and vote upon the
proposal to approve the proposed termination of Repligen Partners and to
transact such other business as may properly come before the special meeting.
Pursuant to the limited partnership agreement dated as of January 9, 1992
among Repligen Development, the purchasers of Class A units and the purchaser
of Class B units, approval and consummation of the termination would result in
the termination, liquidation and dissolution of Repligen Partners.
Record Date; Voting; Quorum
The board of directors of Repligen Development has fixed the close of
business on [date], 2000 as the record date for the special meeting. Only the
limited partners of record on the record date will be entitled to notice of,
and to vote at, the special meeting. A complete list of such limited partners
will be available at [location], for [number] days before the special meeting.
At the special meeting, each limited partner of record on the record date
is entitled to a weighted vote on the termination of Repligen Partners, based
on the amount of limited partnership interests (based on adjusted capital
contributions) held by such limited partner as of the record date. Pursuant to
the limited partnership agreement, the "adjusted capital contribution" with
respect to any limited partner means the aggregate capital contribution of
such limited partner, already made or to be made to Repligen Partners pursuant
to the limited partnership agreement, less any selling commissions, financial
advisory and marketing fees, warrant valuation fees and other fees paid by
Repligen Partners in any fiscal year in respect of such limited partner, or
any portion of any capital contribution which was distributed to the partners
pro rata by Repligen Partners. As of the record date, 712.5 units of limited
partnership interest were issued and outstanding and held by 884 holders of
record. Limited partnership interests represented by properly executed proxies
will, unless such proxies have been previously revoked, be voted in accordance
with the instructions indicated in such proxies. If no instructions are
indicated, these limited partnership interests will be voted for approval of
the termination of Repligen Partners and in the discretion of the proxy holder
as to other matters, if any, incidental to the conduct of the special meeting.
A limited partner who has given a proxy may revoke it at any time prior to its
exercise by giving written notice thereof to the Secretary of Repligen
Development, by signing and returning a later dated proxy or by voting in
person at the special meeting; however, mere attendance at the special meeting
will not itself have the effect of revoking the proxy.
The affirmative vote of the holders of at least 66 2/3% of limited
partnership interests outstanding (based on adjusted capital contributions) as
of the record date is required for approval of the termination of Repligen
Partners. Accordingly, the termination will not be approved unless the holders
of 66 2/3% of limited partnership interests outstanding as of the record date
vote in favor of the termination. Thus, failure to submit a proxy (or vote in
person at the special meeting) or the abstention from voting by a limited
partner and broker non- votes will have the same effect as a vote against the
termination. PaineWebber Development Corporation, the general partner of
PaineWebber R&D Partners III, L.P., has informed the board of directors of
Repligen Development that it intends to vote the Class B limited partnership
interest held by it as well as the 133 Class A limited partnership interests
held by R&D Partners (approximately 16.40% of the limited partnership
interests outstanding) for approval of the termination of Repligen Partners.
5
<PAGE>
There are no quorum requirements with respect to the special meeting,
however, if the limited partners holding 66 2/3% of the limited partnership
interests outstanding do not submit a proxy or vote in person at the special
meeting, the termination of Repligen Partners cannot be approved.
Solicitation of Proxies
Proxies are being solicited by and on behalf of Repligen Partners. All
expenses in connection with the solicitation of the proxies of the limited
partners, including the cost of preparing and mailing this proxy statement
will be borne by Repligen Partners. In addition to solicitation by use of the
mails, proxies may be solicited by directors, officers and employees of
Repligen Partners in person or by telephone, telegram or other means of
communication. Such directors, officers and employees will not be additionally
compensated, but may be reimbursed for reasonable out-of-pocket expenses in
connection with such solicitation. Repligen Partners has retained PaineWebber
and Investor Communications Services, an affiliate of PaineWebber, to aid in
the solicitation of proxies. It is estimated that there will be no fee for
PaineWebber and that the fee for Investor Communications Services will not
exceed $15,000, plus its out-of-pocket costs and expenses. Arrangements will
be made with custodians, nominees and fiduciaries for forwarding of proxy
solicitation materials to limited partners, and Repligen Partners may
reimburse such custodians, nominees and fiduciaries for reasonable expenses
incurred in connection therewith.
No Appraisal Rights
There are no appraisal or dissenters' rights applicable in connection
with the proposed termination of Repligen Partners. Accordingly, any limited
partners who do not vote in favor of the termination will not be entitled to
exercise any appraisal or dissenters' rights in connection with the
termination.
Submission of Matters to a Vote of Security Holders
Except for the matters to which this proxy statement relates, no matters
were submitted to a vote of security holders of Repligen Partners through
solicitation of proxies or otherwise, from the date of organization of
Repligen Partners in January 1992 through the date of this proxy statement.

THE PROPOSED TERMINATION
The Partnership
Organization of the Partnership
Repligen Partners was formed in January 1992 under the laws of the State
of Delaware. The limited partnership agreement, was entered into by and among
Repligen Development, the purchasers of Class A units and the purchasers of
Class B units. On February 28, 1992, Repligen Partners completed a private
offering of (i) 900 Class A units, each unit consisting of one Class A limited
partnership interest in Repligen Partners and a warrant to purchase 2,900
shares of Repligen Corporation's $0.01 par value per share common stock and
(ii) one Class B unit consisting of one Class B limited partnership interest
in Repligen Partners and a warrant to purchase 5,800 shares of Repligen
Corporation's common stock. In addition, Repligen issued a warrant to purchase
13,300 shares of Repligen Corporation's common stock to PaineWebber R&D
Partners III, L.P. and a warrant to purchase 75,050 shares of Repligen
Corporation's common stock to PaineWebber Incorporated. The private placement
resulted in net proceeds of approximately $40,312,500 in cash and non-interest
bearing notes receivable from the limited partners, which were payable in
annual installments through March 15, 1995.
The principal executive offices of Repligen Partners are located at the
offices of Repligen Corporation, 117 Fourth Avenue, Needham, Massachusetts
02194, telephone number (617) 449-9560.
Current Status of the Partnership
Based on the March 1996 decision of the board of directors of Repligen
Development to terminate the research and marketing programs, Repligen
Development assumed responsibility from Repligen Corporation to market the
assets of Repligen Partners without obligation to provide for any royalties or
compensation to Repligen Corporation. Despite the substantial clinical and
development progress of the recombinant platelet factor -4, or rPF4, program,
and the flexibility that Repligen Development has offered in the marketing
effort, it has not been possible to secure a new party to continue the
development of the rPF4-technology. While several third parties have reviewed
the technology, none have made a formal offer for its acquisition.
Upon the termination of the research and marketing programs, Repligen
Development introduced the rPF4- technology for possible acquisition to
numerous pharmaceutical and biotechnology companies and continued the
presentation of the technology to interested parties who had already initiated
preliminary review. The initial contact and presentation phase occurred
primarily during 1996 and 1997. During 1998 and 1999, Repligen Development
continued to market the rPF4-technology to a limited number of parties who
pursued an advanced stage of confidential review. No prospective purchaser,
however, formally offered to acquire the technology.
Recently, Repligen Development was engaged in discussions with a party
interested in acquiring the technology as the foundation for a new company.
After approximately one year of information exchange and discussion, the
prospective purchaser declined to pursue formal contract discussions and in
June 1999 discontinued their efforts to establish a new company to develop the
technology. Subsequent to this event, Repligen Development notified the
companies that had engaged in recent confidential review of the assets, that
the rPF4- technology was available for acquisition on flexible terms. None of
the companies contacted during 1999 have presented an offer to acquire the
technology package. Based on these extensive efforts to market the rPF4-
technology, Repligen Development has concluded that it will not be possible to
sell the assets of Repligen Partners to a third party.
7
<PAGE>
Original Purpose of the Partnership
The principal objectives of Repligen Partners were to develop and derive
income from the sale or license of rPF4 for human therapeutic use in the
United States, Canada and Europe. Platelet factor-4, or PF4, is a naturally
occurring protein which Repligen has produced using recombinant DNA
technology. From early 1992 to February 1996, Repligen Partners and Repligen
Corporation jointly funded multiple clinical trials conducted by Repligen
Corporation for rPF4 to evaluate its use as (i) a cardiac surgical treatment,
serving as a neutralizing agent to reverse the anticoagulant effects of
heparin and (ii) a cancer treatment for certain solid tumor cancers. Pursuant
to an agreement reached with the board of directors, Repligen Corporation
independently funded clinical trials relating to Kaposi's Sarcoma until the
termination of the rPF4 research and development program by the board of
directors on March 8, 1996.
Subsequent Developments
Termination of the rPF4 Development Program. The research program was
terminated by the board of directors of Repligen Development on March 8, 1996.
See "--Termination of Research and Marketing Programs". The following table
summarizes the status of the research program as of [_____________, 1999].

Cardiac Surgical Applications. Repligen Development believes that rPF4
may restore natural coagulation which is disrupted by heparin in
anticoagulated patients undergoing cardiac surgical procedures such as
coronary artery bypass graft, or CABG, surgery. Heparin is an anticoagulant
used to prevent blood from clotting during these cardiovascular procedures. In
certain acute settings, the effects of heparin are reversed chemically with
the generic
8
<PAGE>
drug protamine, which is widely used but has certain adverse side effects.
These side effects, while usually mild to moderate, are occasionally serious,
such as a loss of blood pressure (systemic hypotension), an increase in lung
blood pressure (pulmonary hypertension) or allergic reactions (anaphylaxis).
Over 500,000 patients in the United States undergo open heart surgery and are
treated with protamine each year. Repligen Development believes that rPF4 may
reverse the anticoagulant effects of heparin both more quickly than protamine
and without its potential adverse side effects. Repligen Corporation has a
United States patent on the use of rPF4 or purified PF4 to neutralize heparin
under which, pursuant to the product development agreement dated February 28,
1992 between Repligen Corporation and Repligen Corporation and Repligen
Partners, it has granted to Repligen Partners an irrevocable, exclusive,
royalty-free license to certain patent rights and other technology. See
"--Certain Contracts--Development Agreement".
At the time of the offering of the units, preclinical trials conducted in
rats indicated that rPF4 reversed heparin without causing the systemic
hypotension often associated with protamine. Repligen Corporation and Repligen
Partners subsequently conducted further studies in monkeys and baboons which
confirmed that rPF4 reverses heparin and is safe and effective in those
animals. Because a baboon's cardiovascular system closely resembles that of a
human, Repligen Corporation was able to conduct studies of the reversal of
heparin in the baboon's blood following simulated cardiopulmonary bypass that
provided further support that rPF4 would be safe in human bypass operations.
Subsequent studies of human blood removed from a cardiopulmonary bypass
circuit demonstrated that rPF4 neutralized heparin effectively following
exposure to typical bypass conditions.
In March 1993, Repligen Corporation began a Phase I clinical trial of
rPF4 in cardiac catheterization patients to evaluate its safety. The results
of the study were reported at the annual meeting of the American Heart
Association in November 1993 and demonstrated that rPF4 safely reversed the
anticoagulant effects of heparin in this patient population. Results of the
study were published in the journal Circulation in April 1995. In November
1993, Repligen initiated a double-blind, multi-center Phase II clinical trial
to evaluate the efficacy of rPF4 for the reversal of the anticoagulant effects
of heparin in cardiac catheterization patients in comparison to protamine. The
results of this study were presented at the annual meeting of the American
Heart Association in November 1995 and published in the journal Circulation in
November 1996. These safety data supported continued clinical development of
rPF4 for use in cardiac bypass surgery. Repligen also initiated a Phase I/II
clinical study for the use of rPF4 in cardiopulmonary bypass graft surgery
patients in May 1994. Patient enrollment for this trial was completed in the
first half of 1996. As of March 31, 1998, the preliminary results of this
study confirmed the safety and efficacy of rPF4 in this patient population.
Cancer Applications. At the time of the offering of the units, Repligen
Development believed that rPF4's ability to inhibit the process of new blood
vessel growth, or angiogenesis, represented a novel approach to inhibiting the
growth of solid tumors and that rPF4 may be an effective therapy for a variety
of cancers. Solid tumor development is a complex process that requires the
establishment and expansion of a blood vessel network through angiogenesis. As
a tumor grows beyond microscopic size, passive diffusion from neighboring
tissue is no longer sufficient to meet the nutritional demands of the tumor,
and direct access to capillaries or blood vessels becomes necessary. While the
exact process of angiogenesis is not fully understood, it is believed that new
blood vessels form in response to growth factors that stimulate endothelial
cells, or blood vessel lining cells. Angiogenic growth factors are released by
neighboring tissues that need additional blood supply or by cancer cells. Once
stimulated by these growth factors, the endothelial cells proliferate and
migrate to form the framework for new capillaries and blood vessels. The
inhibition of angiogenesis could be effective in suppressing the growth and
development of solid tumors.
Cancer is treated primarily with surgeries, chemotherapy and radiation
therapy. These treatments often fail to prevent disease progression and spread
of cancer and may have serious adverse side effects. By inhibiting the process
of angiogenesis, Repligen Development believed that rPF4 offered an approach
to the treatment of cancer which could be effective in treating a broad
spectrum of cancers, since virtually all tumors require angiogenesis in order
to survive and grow.

In preclinical testing using several animal cancer models, Repligen
Corporation has shown that the administration of rPF4 significantly inhibited
the growth of solid tumors by a mechanism that was consistent with its
anti-angiogenic activity. Repligen Development believes that rPF4 may be
useful in retarding the progression of Kaposi's sarcoma, or KS, an
AIDS-associated cancer which produces tumors in the skin and internal organs.
In June 1992, Repligen began Phase I clinical trials of rPF4 for treatment of
skin lesions of KS patients by intralesional injection. No significant adverse
reactions attributable to rPF4 were reported during this safety study and the
results of this study were presented at the conference of the American Society
of Clinical Oncology in May 1993. In July 1993, Repligen began a Phase II
clinical trial of intralesional injection in KS patients. Interim results of
this study were reported at the conference of the American Society of Clinical
Oncology held in May 1994. Evidence of biologic activity, and no significant
adverse reactions to rPF4, were reported. A Phase I/II clinical study of
systemic administration of rPF4 to KS patients was initiated in 1994 and
enrolled 13 of 18 patients. rPF4 was well tolerated by the patients and some
evidence of biological activity was observed. This study was closed prior to
completion, on November 29, 1995, due to a lack of financial resources. See
"--Termination of Research and Marketing Programs".
Repligen has conducted several Phase I/II clinical studies of systemic
administration of rPF4 in patients with refractory solid tumors, including
patients with colon carcinoma, renal cell carcinoma and malignant melanoma.
These studies demonstrated that systemic administration of rPF4 was not
associated with clinically significant adverse events. Repligen has been
awarded a United States patent related to the systemic administration of rPF4
to inhibit tumor growth. A Phase I/II clinical study of locally administered
rPF4 in malignant glioma (brain cancer) was initiated in 1994. In this study,
patients with recurrent disease undergo tumor removal and a catheter is
implanted into the site of the tumor bed. rPF4 is then administered directly
into the tumor bed. This study was closed prior to completion on December 28,
1995 due to a lack of financial resources. See "--Termination of Research and
Marketing Programs".
1994 Evaluation; Restructuring of Repligen Warrants. In the spring of
1994, in conjunction with Repligen Development's board of directors' quarterly
review of the research program, and prior to the due date of the third
installment payment from the limited partners under the non-interest bearing
notes, PaineWebber Development Corporation engaged the services of an
independent consultant to evaluate the technical prospects of the rPF4-
related technology. This consultant, Dr. Jordan Gutterman, Professor and
Chairman, Clinical Immunology and Biological Therapy, the University of Texas,
M.D. Anderson Cancer Center, provided a positive review of the potential
effectiveness of rPF4-related technology and endorsed continued development
efforts, but estimated that additional expenditures of approximately $40
million to $50 million might be necessary to produce a commercially viable
version of the rPF4-related technology. These conclusions were reviewed and
confirmed by Dr. Sydney E. Salmon, Regents Professor of Internal Medicine and
Director, Arizona Cancer Center and a member of the board of directors of
Repligen Development.
Based on these reviews as well as on the research and clinical trials
conducted up to that time, Repligen and Repligen Partners determined that the
rPF4-related technology showed significant prospects for successful medical
applications in the cardiac surgical and cancer areas. However, in light of
the higher-than-estimated costs incurred to that point in developing the
rPF4-related technology and the estimated additional expenditures required to
complete the research program, Repligen and Repligen Partners concluded that
Repligen Corporation and Repligen Partners lacked the financial resources
necessary to accomplish those objectives. Repligen Corporation and Repligen
Partners determined that a suitable external source of funds, most likely a
strategic joint venture partner or licensor, with sufficient resources to
carry out the research program and commercialization of rPF4-related
technology was needed. See "--Repligen Efforts to Locate a Strategic Partner:
1994-1996".
Repligen Corporation management felt, however, that the then-existing
royalty commitments to Repligen Partners were such that a third party might be
unable to realize sufficient return from the commercialization of the
rPF4-related technology and that the royalty arrangements would have to be
restructured in order to attract such a strategic partner or licensor.

In March 1994, Repligen offered the holders of Warrants, other than the
warrants issued to PaineWebber Incorporated, the opportunity to exchange their
warrants for newly issued warrants. Each holder of an these warrants was free
to accept or reject the exchange offer. Warrantholders holding warrants to
purchase 2,069,150 shares of Repligen Corporation's common stock accepted the
exchange offer. Warrantholders holding warrants to purchase 258,100 shares of
Repligen's common stock were ineligible to participate in this exchange offer
due to their failure to make payments on their non-interest bearing notes. See
"--Limited Partner Defaults". Warrantholders holding warrants to purchase
288,550 shares of Repligen Corporation's common stock who were eligible to
participate in the exchange offer rejected the exchange offer and thus
continue to hold the warrants.
The exercise price under the warrants offered for exchange is $9.00
(reduced from $22.73) per share but will increase to $14.00 per share 90 days
after Repligen Corporation notifies the warrantholders that the closing price
of Repligen Corporation's common stock is equal to or exceeds $18.00 per share
for any 20 out of 30 consecutive trading days. The exercise period under the
warrants offered for exchange expires on March 31, 2000. Those holders of
warrants who accepted such exchange offer agreed to a reduction in the royalty
rate to 9.00% of net revenue from any sales of rPF4 instead of 12.85% of such
net revenues as initially provided for in the purchase agreement. The exchange
offer did not modify the royalty rates set forth in the product development
agreement, which were unaffected by the termination of Repligen's purchase
option. Acceptance of the exchange offer resulted in pro rata reductions in
certain other royalties. No vote of the warrantholders or the limited partners
was required to accept the exchange offer. Repligen's obligations to pay
royalties under the purchase agreement expired upon the termination of
Repligen Corporation's purchase option. See "--Termination of Research and
Marketing Programs".
1995 Evaluation; Warrant Modification. In March 1995, in conjunction with
Repligen Development's board of directors' quarterly review of the research
program, and prior to the due date of the fourth installment payment from the
limited partners under the non-interest bearing notes, PaineWebber Development
Corporation engaged Dr. Gutterman for a second time to update and review his
evaluation of the rPF4-related technology. Prior to this review, Repligen
Corporation had sponsored a study performed at Thomas Jefferson University in
Philadelphia, Pennsylvania to develop a pharmacoeconomic analysis of the true
incidence and costs of protamine-related adverse events in cardiac surgical
applications. Dr. Gutterman's updated evaluation endorsed continued
development efforts and the pharmacoeconomic study supported the commercial
potential of the rPF4-related technology.
While Repligen Corporation was conducting active discussions with several
potential strategic partners, by early 1995, Repligen Corporation had not
secured an external source of funds to ensure financing of the remainder of
the research program and the subsequent commercialization of the rPF4-related
technology. Repligen Corporation management recognized therefore that a number
of limited partners might decide not to meet their commitments to fund their
fourth and final installment payment to Repligen Partners under the terms of
the notes due on April 19, 1995. Repligen determined that, in light of the
uncertainty surrounding the ability to ultimately secure the funding required
to commercialize the rPF4-related technology, it was advisable to provide
financial incentives to the limited partners to meet their payment
commitments.
In March 1995, Repligen Corporation offered to modify the warrants that
remained outstanding and the warrants offered for exchange. Each holder of an
outstanding warrant or warrant offered for exchange who made the fourth
installment payment pursuant to the non-interest bearing notes was free to
accept or reject the proposed modifications. The modifications provided that
the terms of the warrants would be altered so as to be identical to those of
the warrants offered for exchange when issued in the exchange offer in 1994
(an extension of the exercise period by one year to March 31, 2000 and a per
share exercise price reduced from $22.73 to $9.00, subject to escalation to
$14.00 per share 90 days after Repligen Corporation notifies holders thereof
that the closing price of Repligen Corporation's common stock is equal to or
exceeds $18.00 per share for 20 out of 30 consecutive trading days). The
exercise price of the warrants offered for exchange for the first 1,000 shares
of Repligen Corporation's common stock was reduced from $9.00 per share to
$2.50 per share, and the exercise price for the remaining 1,900 shares of
Repligen Corporation's common stock exercisable pursuant to the modified
warrant offered for exchange was reduced from $9.00 per share to $3.50 per
share. The exercise price of the modified warrants offered for
11
<PAGE>
exchange would, however, increase to $8.00 per share 90 days after Repligen
Corporation's notifies holders thereof that the closing price of its common
stock is equal to or exceeds $12.00 per share for 20 out of 30 consecutive
trading days. Lastly, the offer extended the expiration period for warrants
offered for exchange by one year, to March 31, 2001. The proposed
modifications did not include further reductions in any royalty rates payable
by Repligen Corporation. The difference in treatment between warrants and
warrants offered for exchange was due to the fact that holders of warrants
were those warrantholders who did not accept the 1994 exchange offer and
consequently had a right to receive higher royalty rates than holders of
warrants offered for exchange.
As of December 31, 1995, holders of 620 1/2 of the 712 non-defaulted
Class A units, the holder of the Class B unit and R&D Partners, as holder of
its warrant, had accepted the modifications. Accordingly, as of December 31,
1995, there were issued and outstanding warrants, other than the warrant
issued to PaineWebber Incorporated to purchase 75,400 shares of Repligen
Corporation's common stock, modified warrants to purchase 163,850 shares of
Repligen Corporation's common stock, warrants offered for exchange to purchase
189,950 shares of Repligen Corporation's common stock and modified warrants
offered for exchange to purchase 1,654,700 shares of Repligen's common stock.
Following the close of Repligen Partners' 1995 fiscal year, Repligen Partners
foreclosed on an additional defaulted 1/2 Class A unit, so that as of
September 30, 1998, holders of 620 of the 711 1/2 non-defaulted Class A units
had accepted the modifications, and there were issued and outstanding warrants
to purchase 75,400 shares of Repligen Corporation's common stock, modified
warrants to purchase 163,850 shares of Repligen Corporation's common stock,
warrants offered for exchange to purchase 189,950 shares of Repligen
Corporation's common stock and modified warrants offered for exchange to
purchase 1,653,250 shares of Repligen Corporation's common stock.
Limited Partner Defaults. Class A limited partners owning in the
aggregate 50 Class A units, representing approximately 6 % of the total number
of Class A units then outstanding, failed to make the second installment
payment due March 15, 1993 pursuant to their respective notes. Class A limited
partners owning in the aggregate 39 Class A units, representing approximately
5 % of the total number of Class A units then outstanding, failed to make the
third installment payment due March 15, 1994. The limited partnership
interests and warrants of each such defaulted Class A limited partner were
foreclosed upon by Repligen Partners pursuant to the limited partnership
agreement and each such Class A limited partner was not eligible to
participate in the 1994 exchange offer or the 1995 warrant modification.
Class A limited partners owning in the aggregate 99 1/2 Class A units,
representing approximately 12 % of the total number of Class A units then
outstanding, failed to make the fourth installment payment due March 15, 1995
pursuant to their respective notes and the limited partnership interests and
any warrants and warrants offered for exchange held by each such defaulted
Class A limited partner were foreclosed upon by Repligen Partners pursuant to
the limited partnership agreement, which resulted in a writeoff of
approximately $1,630,000 of notes receivable by Repligen Partners for the
fiscal year ended December 31, 1995. As of December 31, 1995, 712 of the
original 900 Class A units were outstanding. Amounts due as of December 31,
1995 under defaulted non-interest bearing notes receivable from certain
limited partners were approximately $4,000. Following the subsequent
foreclosure by Repligen Partners of the defaulted 1/2 limited partnership unit
relating to such outstanding defaulted non-interest bearing notes receivable,
as of September 30, 1998 711 1/2 of the original 900 Class A units were
outstanding.
Repligen Efforts to Locate a Strategic Partner: 1994-1996. Beginning in
1994, Repligen Corporation attempted to identify one or more strategic
partners to fund the further development of the rPF4-related technology.
Discussions were held by Repligen Corporation and approximately 63 companies
active in the cardiac surgical and cancer fields regarding a variety of
proposals for comprehensive partnerships as well as more specialized joint
ventures or licensing arrangements covering specific treatments (e.g., ocular
applications), discrete activities (e.g., manufacturing) and several
territories.
During 1994, Repligen Corporation participated in advanced negotiations
with a major international pharmaceutical company that was interested in an
exclusive license to market the rPF4-related technology in Europe, but the
discussions ultimately failed to move forward due to concerns that the results
of rPF4 were
12
<PAGE>
preliminary in nature, that the European market would not support an expensive
cancer treatment and that Repligen Corporation's ownership of the commercial
rights to the rPF4-related technology was complicated by Repligen Partners'
rights thereto.
Beginning in 1994, Repligen took certain actions to bolster its financial
position and explored several possibilities of obtaining additional financial
resources to fund various development and commercialization efforts, including
those relating to the rPF4-related technology.
In order to lower expenses and conserve cash resources, Repligen
Corporation underwent two successive downsizings from July 1994 to March 1995
which together with attrition reduced its workforce by approximately 170
employees, or roughly 47 percent, and discontinued or postponed certain
clinical programs. Following the restructurings, the primary focus of Repligen
management centered on the clinical development and commercialization of the
rPF4-related technology as well as other independently funded development
programs.
In the spring of 1995, Repligen Corporation entered into merger
negotiations with Medco Research Inc., a biotechnology company specializing in
diagnostic and therapeutic products in the cardiovascular and cancer areas. On
May 23, 1995, the two companies publicly announced that their respective
boards had approved a letter of intent to enter into a non-cash merger wherein
Medco would issue to holders of Repligen Corporation's common stock between
3.2 million and 3.4 million shares of its common stock with a then-current
market value of approximately $51.5 million. Medco would have added roughly
$40 million in additional cash to the balance sheet of the post-merger entity,
although such additional amounts would have been available to support
pre-existing Medco research, development and commercialization activities as
well as rPF4 development and commercialization activities. On July 11, 1995,
Repligen Corporation and Medco announced that they had ended merger
negotiations after failure to agree on the valuation of Repligen Corporation's
common stock to be used as the basis for the proposed merger.
On June 1, 1995, Repligen Corporation and Eli Lilly and Company announced
that they had reached agreement to extend through 1996 a collaboration and
license agreement initiated in May 1992 relating to the development of
monoclonal antibodies designed to fight inflammatory diseases. However, in
early September 1996, Eli Lilly elected to discontinue the collaboration,
citing a reallocation of resources for its research priorities.
In September 1995, Repligen Corporation sold its immune modulation
program to Genetics Institute, Inc., while retaining rights to independently
commercialize certain small molecule-based drugs in the same therapeutic area.
In December 1995, Repligen Corporation reached an advanced stage of
discussions regarding the rPF4-related technology with another major
international pharmaceutical firm, which ultimately decided not to license the
rPF4-related technology due to the firm's lack of, and costs associated with
establishing, microbial manufacturing capacity.
On December 12, 1995, Repligen Corporation and Apotex USA announced that
they had reached a tentative agreement for the sale of Repligen Corporation's
Allegro Biologics division, consisting of its process development and contract
manufacturing operations, to Apotex. Under the terms of the agreement, Apotex
was to acquire all of the Allegro assets, as well as Repligen Corporation's
Protein A and diagnostic reagents business. In addition, Allegro and Repligen
Corporation were to enter into an agreement to develop and produce
pharmaceuticals for Repligen Corporation's clinical development programs. On
January 19, 1996, Repligen Corporation announced that the acquisition
negotiations had ended, citing strategic reasons internal to Apotex.
On February 12, 1996, Repligen Corporation and Genzyme Corporation
announced tentative agreement on the sale of the assets of Allegro as well as
Repligen Corporation's Protein A business and certain related assets to
Genzyme. However, on April 9, 1996, Repligen Corporation announced that the
negotiations had not resulted in a definitive agreement due to differences
between the parties as to the valuations of the Allegro assets, the Protein A
business and associated fixed assets.
13
<PAGE>
In early 1996, Repligen Corporation entered into acquisition negotiations
with Glycan Pharmaceuticals, Inc., a biotechnology company focusing on small
molecule therapeutics for inflammatory and proliferative diseases. Glycan had
been founded by three former Repligen scientists. On March 14, 1996, Repligen
Corporation publicly announced that it had acquired Glycan. Under the terms of
the asset purchase agreement, Repligen Corporation's existing Chief Executive
Officer, Vice President of Research and Development and Vice President of
Business Development were each succeeded by one of the Glycan founders. The
Glycan acquisition did not, however, result in the introduction of sufficient
additional capital or otherwise increase the financial resources available to
Repligen Corporation such that it would be in a position to fund continued
development and subsequent commercialization of the rPF4-related technology.
Termination of Research and Marketing Programs
At a regular quarterly meeting of the board of directors of Repligen
Development held on March 8, 1996, the board of directors reviewed the
then-current status of the research and development program being conducted by
Repligen Corporation pursuant to the product development agreement, the
prospects for the successful commercialization of the background technology
and the financial resources necessary to support such commercialization, as
well as the financial resources available to Repligen Corporation and Repligen
Partners. The board of directors of Repligen Development and the Repligen
Corporation representatives present at the meeting agreed that at least $50
million in additional funds would be required to complete the research program
and commence the sale of products derived from the rPF4-related technology as
provided in the product development agreement. The board of directors noted
that the remaining cash resources of Repligen Partners at that time totaled
approximately $385,000.
The Repligen Corporation representatives stated that, given the limited
resources available to it, Repligen Corporation would no longer be in a
position to contribute the funds necessary to continue the research program.
The Repligen Corporation representatives also advised the board of directors
of Repligen Development that, despite its continuing efforts to seek funding
from potential third-party collaborators, it could not obtain such funding in
the immediate future.
Pursuant to the terms of the product development agreement, the board of
directors of Repligen Development unanimously determined, based on the above
factors, that the continuation of the research program and the commencement of
the marketing program with Repligen Corporation would be economically
impracticable and therefore terminated both in their entirety.
Under the terms of the product development agreement, upon the
termination of the research and marketing programs by the board of directors
of Repligen Development, Repligen Corporation relinquished its rights to
manage the clinical development of the rPF4-related technology as well as any
rights to exploit or use the rPF4- related technology in the United States,
Canada and Europe and to receive management fees and the reimbursement of
certain expenses relating to the research program and the rPF4-related
technology. Repligen Corporation retained responsibility for indefinitely
maintaining, at its own expense, all records, including a library of
biological, chemical and other physical materials, relating to the
rPF4-related technology. In addition, under the terms of the purchase
agreement, the termination of the research and marketing programs caused
Repligen Corporation's option to purchase the limited partnership interests of
the limited partners to likewise terminate, and set an interim license
termination date to occur eighteen months thereafter, on September 8, 1998.
The board of directors of Repligen Development noted that while the remaining
cash available to Repligen Partners was insufficient to continue meaningful
funding of the research program, it might be sufficient to meet the estimated
expenses of marketing and disposing of the rPF4-related technology to one or
more third parties. The board then directed the officers of Repligen Partners
to actively seek a buyer or licensor for the rPF4-related technology.
Subsequent to the March 8, 1996 board of directors meeting, the
Repligen-designated members of the board of directors of Repligen Development
resigned, and Repligen Corporation and Repligen Partners entered into
discussions regarding certain proposed modifications to each party's rights
and responsibilities with respect to the
14
<PAGE>
termination of the research and marketing programs and efforts to market the
rPF4-related technology to third parties, but did not reach agreement on the
desirability of any modifications to the existing contractual arrangements.
From the beginning of 1996, and in particular following the termination
of the research and marketing programs on March 8, 1996, officers of Repligen
Partners conducted intensive efforts to sell or license the rPF4- related
technology to a third party or locate a suitable strategic partner to
otherwise fund further development of the rPF4-related technology.
Certain Contracts
Product Development Agreement. In connection with the organization of
Repligen Partners, Repligen Partners and Repligen Corporation entered into the
product development agreement pursuant to the terms of which Repligen
Corporation granted to Repligen Partners an exclusive, royalty-free license to
certain patent rights and other technology owned or controlled by Repligen
Corporation relating to the manufacture, use and sale of rPF4-related products
covered by such agreement. The license granted to Repligen Partners is limited
to the rPF4-related technology, necessary or materially useful for the
development and commercialization of products for human therapeutic use in the
United States, Canada and Europe.
Until the termination of the research and marketing programs by the board
of directors of Repligen Development on March 8, 1996, the product development
agreement required Repligen Corporation, to the extent permitted by
partnership funds, to use its best efforts to perform the research program and
seek to obtain approval from the United States Food and Drug Administration
for the sale of products that may be developed utilizing the licensed
technology. In addition, Repligen Corporation agreed to use its best efforts
to manufacture and market the products in the United States, Canada and Europe
directly or through third parties in those places. Repligen Partners was
required to reimburse Repligen Corporation for its research and development
expenses on behalf of Repligen Partners, plus a management fee of ten percent
(10%) of such expenses. If at any time Repligen Partners' funds (or any
additional funds provided by Repligen Corporation) shall have been expended
and no FDA marketing approval shall have been received for the sale by or on
behalf of Repligen Partners of any product in the United States, Canada and
Europe, Repligen Development was to determine the amount of additional funds
required by Repligen Partners in the upcoming year, and Repligen Corporation
would have the right to contribute such funds to Repligen Partners. Any such
contribution would not result in dilution of the limited partners' interest in
Repligen Partners. Payments by Repligen Partners were required to be made at
the end of each calendar quarter, except that (i) if such amount exceeded the
amount stated in the budget for such quarter, Repligen Partners was only
required to pay such excess as was approved by the board of directors and (ii)
if such amount exceeded Repligen Partners' available funds, Repligen Partners
was not obligated to pay such excess until receipt of additional funds.
The product development agreement also requires Repligen Corporation to
pay to Repligen Partners royalties equal to 6% of revenues on sales of any
competitive products in the United States, Canada and Europe. These payments
continue to be payable until March 8, 2001. There are currently no such
competitive products, although we cannot assure you that there will not be any
such competitive products in the future.
Prior to the end of each quarter of each year, until the termination of
the research and marketing programs by the board of directors on March 8,
1996, Repligen Development reviewed the progress of the research program
during the preceding three-month period to determine whether the continuation
of all or any part thereof was in the best interests of the limited partners
of Repligen Partners. If at any time the board of directors were to determine
that the research program was infeasible or uneconomic and should be
discontinued with respect to all products, or if the board of directors were
to determine not to contribute the additional funds to Repligen Partners which
were determined by Repligen Development to be required when all partnership
funds had been expended and no FDA marketing approval had been received for
the sale of any product in the United States, Canada and Europe, the board of
directors could terminate the research and marketing programs. In the course
of the board of directors' reviews in the first quarters of 1994 and 1995,
PaineWebber Development Corporation engaged the services of
15
<PAGE>
independent consultants, who provided favorable evaluations of the technical
prospects of the rPF4-related technology. See "--1994 Evaluation;
Restructuring of Repligen Warrants" and "--1995 Evaluation; Warrant
Modifications". However, on March 8, 1996, Repligen Corporation advised
Repligen Partners that it did not currently have nor did it anticipate
generating funds sufficient in aggregate amount to finance the remainder of
the research program and the marketing program. As a result, the board of
directors terminated the programs. See "--Termination of Research and
Marketing Programs". The termination of the programs provides Repligen
Partners with the right to freely transfer the license to one or more third
parties.
Purchase Agreement. Also in connection with the organization of Repligen
Partners, Repligen Corporation and Repligen Partners entered into a purchase
agreement, amended and restated as of February 28, 1992, pursuant to which
Repligen Corporation agreed to use its best efforts to manufacture products
and to sell the products for use in the territories or, if Repligen
Corporation determined that such manufacture and sale was not commercially
practicable, to use its best efforts to license or sell the rPF4-related
technology to a third party. Upon the first marketing approval of rPF4 by the
FDA, Repligen Partners would receive a payment equal to 20 percent of the
aggregate capital contributions of all limited partners, payable at Repligen
Corporation's option in cash or in Repligen Corporation's common stock. Under
the terms of the purchase agreement, and in exchange for the issuance of the
warrants, each limited partner granted to Repligen Corporation an irrevocable
option to purchase its interest in Repligen Partners. This purchase option was
exercisable only if all interests were to be purchased and such option was
exercisable by sending a notice to all the limited partners on a date during
the forty-five day period commencing on the date which was the earlier of (i)
the date which was the later of the last day of the first month in which
Repligen Partners received interim license payments equal to fifteen percent
(15%) of the limited partners' capital contributions and the last day of the
twenty-fourth month period after the date of Repligen Partners' first
commercial sale of any product within the specified territories and (ii) the
last day of the forty-eighth month after the date of such first commercial
sale.
The purchase option was to terminate upon the occurrence of any of the
following termination events: (i) the bankruptcy of Repligen Corporation, (ii)
the cessation of operations by Repligen Corporation, (iii) the seizure or
attachment of all or a substantial part of Repligen Corporation's assets or
(iv) the termination of the research and marketing programs. In addition, the
purchase option was to terminate upon the earlier of (i) Repligen's notice to
Repligen Partners and the limited partners that it did not intend to exercise
the purchase option or (ii) the expiration unexercised of the purchase option.
After any such termination, Repligen Partners is free to license or sell the
rPF4- related technology. On March 8, 1996, the board of directors of Repligen
Development terminated the research and marketing programs, which in turn
terminated the purchase option. See "--Termination of Research and Marketing
Programs". Accordingly, the rPF4-related technology is no longer encumbered
and may be sold or licensed to third parties by Repligen Partners.
Patents, Licenses and Proprietary Rights
Repligen Development believes that the proprietary protection of rPF4 has
improved since the time of the offering of the units. At the time of the
offering, patent applications filed by a subsidiary of Bristol-Myers Squibb
Company were disclosed as having the ability to potentially block Repligen
Partners' ability to market rPF4. In July 1993, Repligen Corporation and
Bristol-Myers Squibb Company entered into an exclusive, worldwide,
royalty-free license agreement covering an issued U.S. patent and pending
foreign patent applications, the effect of which is to prevent Bristol-Myers
Squibb Company from using these patents to block the ability of Repligen
Corporation to market rPF4 as an anti-cancer agent or as an agent for heparin
neutralization. In April 1993, the United States Patent and Trademark Office
issued Repligen Corporation a patent covering the use of purified PF4 and rPF4
to neutralize heparin. In February 1994, the Office issued Repligen
Corporation a patent for the systemic administration of rPF4 to inhibit tumor
growth in patients with metastatic cancer. Patent applications have been filed
by Repligen Corporation for these uses in Canada, Europe and Japan and certain
other uses of rPF4 in the United States, Canada, Europe and Japan. The rights
that Repligen Corporation may possess with respect to such patents and patent
applications within the territory specified in the limited partnership
agreement, insofar as they relate to the
16
<PAGE>
technology inure to the benefit of Repligen Partners as holder of the license,
as well as to any third-party transferee of the license.
Competition
Repligen Development is not aware of any other current efforts to develop
PF4 or rPF4 for therapeutic use. Several competitors in the pharmaceutical and
biopharmaceutical industries have substantial research programs underway in
oncology utilizing a broad spectrum of therapeutic approaches, including
chemotherapy, various recombinant cytokines and monoclonal antibody-,
antisense- and gene therapy-based technologies, any or all of which may become
competitive with Repligen Partners' products.
The only product approved by the FDA for heparin neutralization is the
generic drug protamine, which is produced and marketed by three companies.
Currently, other than experimental agents, no substitute compounds are
available for post-surgical reversal of heparin. Repligen Development is aware
of three companies with products in development as of May 1999 for heparin
reversal applications. Ibex Technologies, Inc. is developing heparinase, an
enzyme that breaks down heparin, which has completed Phase II clinical trials.
The company reported the initiation of pivotal Phase III studies, which were
suspended during the Summer of 1999 pending the acquisition of additional
funding to continue product development. Commonwealth Biotechnologies, Inc. is
developing a heparin binding polypeptide, and Gem Pharmaceuticals is
developing recombinant lactoferrin as a heparin reversal agent. To the best of
Repligen Development's knowledge, heparin reversal clinical trials have not
yet begun with these latter two agents. A heparin binding cartridge previously
considered for cardiac bypass applications by Research Industries Corporation
is not believed to have advanced in development to human clinical studies.
Currently, except for experimental agents, no specific antiangiogenic
agents have been approved for human therapy. It is clear, however, that many
companies are currently seeking to develop other compounds to inhibit
angiogenesis. Of companies developing protein-based angiogenesis inhibitors,
Entremed Corporation has received substantial recent attention concerning the
development of two agents: endostatin and angiostatin, that were discovered
after the formation of the limited partnership. No direct comparative tests
have been conducted between these newer agents and rPF4, and the relative
value of the agents can not be clearly established. The perception that the
newer compounds may have greater therapeutic effect than rPF4, however, has
probably negatively affected the ability to secure a new partner or purchaser
for the assets of Repligen Partners. Antibody-based therapeutic agents and
small molecule angiogenesis inhibitors are also under development at numerous
biotechnology and pharmaceutical companies, and new approaches for inhibiting
angiogenesis have been emerging with increasing frequency as basic research in
this field has expanded over the last five years. The general increase in
competition, the emergence of new angiostatic mechanisms, and the perception
that certain agents may possess special advantages have significantly
confounded the efforts to acquire a corporate partner or secure independent
funding to continue the rPF4 development program. It is also likely that there
are companies developing angiogenesis inhibitors and heparin neutralizing
agents of which Repligen development is unaware.
Given the current, significant financial constraints faced by Repligen
Partners, see "--Termination of Research and Marketing Programs" and "Selected
Financial Information--Management's Discussion and Analysis of Financial
Condition and Results of Operations", most if not all of the competitors of
Repligen Partners have significantly greater financial resources, more
extensive research and development capabilities and greater marketing and
human resources than either Repligen or Repligen Partners. Some companies have
a competitive advantage over Repligen Partners because of greater potential
funding for research and development and more established drug manufacturing
capabilities and distribution channels.

Government Regulation
The development and commercialization of the rPF4-related technology is
subject to extensive regulation for safety and efficacy by numerous
governmental authorities in the United States and other countries. In the
United States, the development and commercialization of the rPF4-related
technology is subject to rigorous regulation by the FDA, and other Federal,
state and local agencies governing, among other things, research and
development activities and the testing, manufacturing, safety, effectiveness,
labeling, storage, record keeping, approval, advertising and promotion of the
rPF4-related technology and products derived therefrom. Further, additional
government regulation may be established which could affect regulatory
approval of such products.
The standard process required by the FDA before a pharmaceutical agent,
such as a new drug or biologic, may be marketed in the United States includes
(i) preclinical laboratory and animal tests, (ii) submission to the FDA of an
Investigational New Drug, or IND application, which must become effective
before human clinical trials may commence, (iii) adequate and well-controlled
human clinical trials to establish the safety and efficacy of the agent in its
intended indication, (iv) submission to the FDA of a marketing application
such as a New Drug Application, or NDA, or a Biologics License Application, or
BLA, and (v) FDA approval of the NDA or BLA prior to any commercial sale or
shipment of the prospective new product. In addition to obtaining FDA approval
for each product, each of its domestic and foreign manufacturing
establishments must comply with the FDA's current good manufacturing practices
as appropriate for production. Domestic and foreign manufacturing
establishments are subject to inspections by the FDA and by regulatory
authorities in other countries.
Clinical trials are typically conducted in three sequential phases, which
may overlap. In Phase I, the initial introduction of the agent to humans, the
new drug or biologic is tested for safety, dosage tolerance and metabolism.
Phase II involves studies in a limited patient population to (i) assess the
preliminary effectiveness of the agent for specific targeted indications, (ii)
determine dosage tolerance and optimal dosage and (iii) identify possible
adverse effects and safety risks. When an agent is found to be effective and
to have an acceptable safety profile in Phase II evaluations, Phase III trials
are undertaken to establish statistical evidence of clinical efficacy and to
further test for safety within an expanded patient population at
geographically dispersed clinical study sites. There can be no assurance that
Phase I, Phase II or Phase III testing will be completed successfully within
any specified time period, if at all, with respect to any of Repligen
Partners' products subject to such testing.
The process of completing clinical testing and obtaining FDA approval for
a new human drug or biologic is likely to take a number of years and require
the expenditure of substantial resources. Even after initial FDA approval has
been obtained, further studies may be required to provide additional data on
safety or to gain approval for the use of a product as a treatment for
clinical indications other than those for which the product was initially
tested. Also, the FDA may require post-marketing testing and surveillance
programs to monitor the drug's efficacy and side effects. Results of these
post-marketing programs may prevent or limit the further marketing of the
products.
Human Resources
Repligen Partners and Repligen Development do not have any full-time
employees.
Description of Property
Repligen Partners does not own or lease any real property. Repligen
Partners' business had been conducted by Repligen Corporation in its
administrative, laboratory and production space at One Kendall Square in
Cambridge, Massachusetts pursuant to the product development agreement.
Effective June 1, 1996, Repligen Corporation relocated its administrative,
laboratory and production activities to 117 Fourth Avenue, Needham,
Massachusetts.
Under the product development agreement, Repligen Corporation has an
indefinite obligation to store, preserve and maintain all materials, documents
and other records (including certain physical, chemical and biological
18
<PAGE>
specimens) relating to the rPF4-related technology and make same reasonably
available to Repligen Partners, its representatives and any third-party
licensees or successors in interest thereto. Repligen's ability to comply with
these obligations may be limited by its available financial and other
resources.
Legal Proceedings
Repligen Partners is not aware of any material pending legal proceedings
to which Repligen Partners is a party or of which any of its property is the
subject.
Background of the Proposed Termination
Repligen Partners was formed to develop rPF4 for acute use as a heparin
reversal agent in cardiac surgical applications and for repeat administration
as a cancer therapy due to its ability to inhibit angiogenesis. Repligen
Partners' funds were expected to be adequate to complete Phase I and II
studies for heparin reversal and exploratory Phase I/II studies for cancer
applications, with additional funding for Phase III development expected to be
obtained from other private, public or corporate sources.
Repligen Partners successfully completed studies that demonstrated the
efficacy of rPF4 for neutralization of heparin in two patient populations:
cardiac catheterization and cardiac bypass surgery. Preliminary effective
doses were established for each application and initiation of Phase III
studies to definitively establish the appropriate dose and build a
comprehensive safety profile were considered warranted. During the course of
the development activities increasing attention to healthcare reform and cost
control increased the need to build a comprehensive pharmacoeconomic rationale
supporting the development of rPF4 which consumed a larger than anticipated
portion of partnership resources and time. Furthermore, the development of a
high productivity and cost-effective method to manufacture the protein
consistent with a pharmacoeconomic rationale required greater than expected
effort and affected time lines and development strategies for the development
of the agent. Although Repligen Partners believed that a strong rationale
based on pharmacoeconomic principals was built with early studies, it was
recognized that definitive demonstration of cost/benefit relationship would
require comprehensive evaluation in later Phase III or IV studies which
reduced the ability of Repligen Partners to market the rPF4-technology.
Multiple Phase I/II studies of rPF4 in late-stage cancer patients were
conducted that demonstrated that the agent was generally well tolerated when
administered by a variety of routes at the doses tested. Due to productivity
limitations of early manufacturing processes and higher prioritization of
development of the heparin reversal application, dose levels in cancer studies
were often limited by the amount of available material. Although dose limiting
toxicities were not encountered during the cancer studies which were
completed, definitive demonstration of therapeutic activity could not be
established, requiring the pursuit of additional exploratory studies at higher
doses, alternative schedules, and/or in other patient populations. Although
Repligen Partners believes that the results of the early cancer studies are
consistent with expectations for an agent with angiostatic properties such as
rPF4, the lack of clear therapeutic efficacy and lack of understanding of its
mechanism of activity further reduced the ability of Repligen Partners to
market the rPF4-technology.
During the development of rPF4, Repligen Corporation, on behalf of
Repligen Partners, explored numerous opportunities to partner the
rPF4-technology with pharmaceutical and biotechnology companies with an
interest in either, or preferably both, of the applications of the agent.
Several of the discussions progressed to advanced stages of due diligence but
did not result in formal offers to develop the technology. In addition to the
issues cited above the lack of success of the partnering efforts was often
attributed to the uncertainties concerning the cost of further development and
the level of royalties and milestone payments that would be due to limited
partners. In parallel to these partnering efforts Repligen Corporation was
experiencing financial difficulties, failed to complete a merger, and executed
several rounds of restructuring (See: "Repligen Efforts to Locate a Strategic
Partner: 1994-1996"). Throughout this time public financial markets were not
considered to be a viable option to fund the continued rPF4 development
efforts. Ultimately, the board of directors of Repligen Development terminated
the research and marketing programs (See: "Recent Developments - Termination
of Research and Marketing Programs").
19
<PAGE>
From 1996 until the present, Repligen Development has acted independently
of Repligen Corporation to market the rPF4 technology. During 1996 and 1997
Repligen Development introduced the rPF4-technology for possible acquisition
to numerous pharmaceutical and biotechnology companies and continued the
presentation of the partnership technology to interested parties who had
already initiated preliminary review. Furthermore, during 1998 and 1999
Repligen Development continued to market the rPF4-technology to a limited
number of parties who pursued an advanced stage of confidential review and
suggested that a restructuring of Repligen Partners could be considered.
During that effort no prospective purchaser formally offered to acquire the
technology due to reasons similar to those described above. Based on the lack
of current active interest in acquiring the technology and the previous
experiences in the marketing effort, Repligen Development does not believe
that the expense of further marketing of the technology is warranted.
Recommendation of Repligen Development; Reasons for the Proposed Termination
At a meeting of the board of directors of Repligen Development held on [
], 2000, the board of directors unanimously adopted resolutions (i) expressing
the board's belief that the termination is in the best interests of Repligen
Partners and its limited partners, (ii) approving and declaring advisable the
proposed termination, subject to approval by the limited partners and (iii)
recommending that the limited partners vote for approval of the termination.
Repligen Development has made this determination based on its assessment of
(i) Repligen Partners' financial condition and prospects and (ii) the
availability, feasibility and effect on the limited partners of alternatives
to the termination. In assessing Repligen Partners' financial condition,
prospects and remaining assets, Repligen Development considered the following
factors:
1. The absence of a buyer for the rPF4 technology.
2. The failure of the rPF4 technology to achieve marketing approval.
3. The possible tax benefit to limited partners of immediate termination.
4. If Repligen Partners is not terminated, limited partners may share in
royalties paid to by Repligen on sales of competing products, if any, through
March 8, 2001.
5. If Repligen Partners is not terminated, there is a possibility that a
buyer for its assets will be identified.
Thus, the general partner recommends that the limited partners vote for
approval of the termination.
20
<PAGE>
TERMINATION AND DISSOLUTION OF THE PARTNERSHIP
General
Approval and consummation of the termination by holders of at least
66 2/3% of the limited partnership interests outstanding as of the record date
will also liquidate Repligen Partners under the terms of the limited
partnership agreement. Upon termination of Repligen Partners, the affairs of
Repligen Partners will be wound up and all of its debts and liabilities will
be discharged in the order of priority as provided by law. The capital
accounts of the limited partners then will be allocated items of net gain or
net loss as if there had been a taxable disposition of all of the assets of
Repligen Partners. See "Certain Federal Income Tax Consequences".
After the capital accounts of the Partners have been adjusted for certain
allocations and for all other items attributable to the taxable year in which
Repligen Partners terminates, and by the end of the taxable year in which
Repligen Partners terminates (or, if later, within 90 days after the date of
such termination), any remaining assets of Repligen Partners will be
distributed to those limited partners with positive capital account balances
in proportion to such positive capital account balances. If such distributions
are insufficient to return to any limited partner the full amount of his
capital contribution, he will have no recourse against any other limited
partner or any other party under the terms of the limited partnership
agreement.
The winding up of the affairs of Repligen Partners will be conducted
exclusively by Repligen Development (or if at such time there shall be no
Repligen Development, then by such person as may be appointed by the vote of
66 2/3% in interest (based on adjusted capital contributions) of the limited
partners). Repligen Development (or such appointee), in carrying out such
winding up and distribution, will have full power and authority to sell all or
any of Repligen Partners' assets or to distribute the same in kind to the
limited partners. Any assets distributed in kind will be subject to all
operating agreements or other agreements relating thereto which survive the
termination of Repligen Partners.
As the remaining non-cash assets of Repligen Partners will be abandoned
by the Board of Directors of Repligen Development prior to the termination,
Repligen Development estimates that no amounts will be available for
distribution to limited partners on termination and liquidation.
Upon the consummation of the liquidation, Repligen Partners will file a
certificate of cancellation with the Secretary of State of the State of
Delaware in accordance with Section 17-203 of the Delaware Revised Uniform
Limited Partnership Act. After the filing of the certificate of cancellation,
Repligen Partners will no longer be authorized to undertake partnership
actions other than those necessary for winding-up its affairs.
Various laws for the protection of creditors may apply to the
liquidation. In this regard, it should be noted that if a court were to find
that Repligen Partners failed to provide sufficient funds for the liabilities
of Repligen Partners, or that the liquidating distribution to the partners, if
any, rendered Repligen Partners insolvent, the liquidating distributions to
the partners may be deemed to be "fraudulent conveyances" or impermissible
dividends or distributions under applicable law, and therefore may be subject
to claims of certain creditors of Repligen Partners, if such creditors have
not been paid. In the event that such a claim is asserted after the
liquidation, there is a risk that persons who were Partners on the
distribution record date will be ordered by a court to turn over to Repligen
Partners' creditors all or a portion of the liquidating distributions they
received from Repligen Partners.
Certain Federal Income Tax Consequences
This summary outlines certain Federal income tax principles applicable to
limited partners in connection with the liquidation. This summary deals only
with the treatment of a limited partner who acquired his interest for cash
pursuant to the February 28, 1992 private offering. There are numerous other
Federal income tax principles not discussed herein that may be important to a
limited partner in connection with Repligen Partners. Each limited
21
<PAGE>
partner is urged to consult his own tax advisor concerning his investment in
Repligen Partners and the possible tax consequences of the liquidation.
Each limited partner will recognize a net loss in connection with the
liquidation equal his adjusted basis in his limited partnership interest.
Repligen Partners intends to take the position that it incurs an ordinary
loss in connection with the liquidation, a distributive share of which is
allocated in turn to each limited partner. The Internal Revenue Service,
however, may seek to disallow any such ordinary loss and to characterize each
limited partner's loss as a capital loss, the deductibility of which would be
subject to limitations.

MARKET PRICES OF AND DISTRIBUTIONS ON THE
LIMITED PARTNERSHIP INTERESTS AND RELATED MATTERS
No public or other market exists or will develop for the units or the
limited partnership interests. Neither the units nor the limited partnership
interests are transferable without the consent of Repligen Development and
satisfaction of certain other conditions contained in Article 8 of the limited
partnership agreement.
The following information relates to the ownership of units and interests
as of ____________, 1999.
Title of Class Number of Record Holders
- ------------------------------------------- ------------------------
Repligen Development Interest 1
Class A Units/Limited Partnership Interests 711.5
Class B Units/Limited Partnership Interests 1
There have been no distributions to the partners to date. Distributions
in the future, if any, will be made by Repligen Partners to the partners as
soon as practicable after the end of any fiscal quarter, in proportion to the
partners' respective capital accounts as of the end of such quarter.
Distributable cash, which must be distributed to the partners, is generally
defined as the excess of cash revenues over certain expenditures and other
amounts determined by Repligen Development to be necessary for the proper
operation of Repligen Partners' business. The capital account of each partner
will be increased by such partner's cash contributions (net of selling
commissions, investment banking fees, warrant valuation fees and financial
advisory fees allocated to the partner) to Repligen Partners decreased by the
amount of any cash distribution and the fair market value of other property
from Repligen Partners to such partner, and increased or decreased by such
partner's allocation of the net gain or loss of Repligen Partners for federal
income tax purposes ("Profits" and "Losses", respectively). Partnership
profits and losses are allocated 99% to the limited partners (pro rata to
their capital accounts) and 1% to Repligen Development.
Following the termination on March 8, 1996 of Repligen's option to
purchase the limited partnership interests pursuant to the purchase agreement,
neither Repligen Development's interest nor, to the best of Repligen
Development's knowledge, any limited partner's unit/limited partnership
interest: (i) is subject to any outstanding options or warrants to purchase,
or securities convertible into, any equity interest of Repligen Partners; (ii)
could currently be sold pursuant to Rule 144 under the Securities Act of 1933,
as amended, or is subject to agreement by Repligen Partners to be registered
under the Securities Act of 1933 for sale by security holders; or (iii) is
being, or has been publicly proposed to be, publicly offered by Repligen
Partners.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS
Results of Operations
Repligen Partners received no revenue for the nine month period ended
September 30, 1999 or for the year ending December 31, 1998. Repligen
Partners' sole source of revenue for the years ended December 31, 1997 and
1996 was interest income earned on capital contributions prior to
disbursements for partnership activities. Interest income for the year ended
December 31, 1997 was $1,509 compared to $14,425 in the comparable fiscal 1996
period. The decrease in investment income in fiscal 1997 and 1998 was due to
the decrease in available funds for investment as the effort to market the
partnership assets proceeded during the course of the years.
Repligen Partners incurred no research and development expenses for the
nine month period ended September 30, 1999 and 1998. Total research and
development expenses for the year ended December 31, 1997 were $8,513 as
compared to $422,296 in the comparable fiscal 1996 period. The decrease in
research and development expenses reflects a significant reduction in
research, development and clinical trial expenditures incurred under the
product development agreement with Repligen Corporation, in particular as a
result of the termination of the research program and marketing program by the
board of directors of Repligen Development on March 8, 1996. Expenses largely
consisted of costs incurred in connection with the orderly close-out of
rPF4-related clinical activities in compliance with FDA regulations and in a
manner considered appropriate for the preservation of partnership assets for
potential future sale or transfer.
For the nine month period ended September 30, 1999 general and
administrative expenses were $262 as compared to $15,036 for the nine month
period ended September 30, 1998. General and administrative expenses were
$62,446, $98,174 and $236,798 for the years ended December 31, 1998, 1997, and
1996 respectively. The decrease in general and administrative expenses
primarily reflects the decrease in direct personnel associated with the
rPF4-related technology marketing activities described under "The Proposed
Termination--Subsequent Developments--Repligen Efforts to Locate a Strategic
Partner: 1994-1996", and the reduced administrative expenses paid to Repligen
Corporation due to the termination of the research program. Repligen Partners
paid Repligen Corporation a management fee equal to 10% of total expenses
incurred on behalf of Repligen Partners.
Capital Resources and Liquidity
Repligen Partners' primary source of funding and capital resources has
been the capital contributions made by the limited partners and Repligen
Development, which have totaled approximately $40,582,000 since inception. Of
this total, approximately $11,792,000, $11,375,000, $10,354,000 and $7,061,000
were received during 1995, 1994, 1993 and 1992, respectively. During 1996,
1995 and 1994, Repligen Partners wrote off approximately $4,000, $1,637,000
and $3,325,000 of notes receivable, respectively, relating to limited
partnership units which were foreclosed for failure to pay their installments.
As of September 30, 1999, 711 1/2 of the original 900 Class A Units were
outstanding.
As of September 30, 1999 and December 31, 1998, Repligen Partners did not
owe any amounts to Repligen Corporation. As of December 31, 1997, Repligen
Partners owed Repligen Corporation $500 for management fees associated with
the coordination of partnership matters. As of December 31, 1996 and 1995,
Repligen Partners owed Repligen Corporation approximately $2,200 and $2,000,
respectively, for amounts due under the product development agreement,
interest relating to the note payable and unreimbursed expenses incurred on
behalf of Repligen Partners. In addition, as of December 31, 1994, Repligen
Partners owed Repligen Corporation a note payable of $4,620,000 as a result of
a loan from Repligen Corporation to Repligen Partners to fund some
organization and syndication costs. The note evidencing this loan was secured
by a pledge of the notes receivable from the partners, bearing interest at
8.5% payable annually in arrears. The note and accrued interest was paid in
May 1995 upon receipt of proceeds from the non-interest bearing notes
receivable from the limited partners.
25
<PAGE>
During 1998 and 1997 Repligen Partners made payments to Repligen
Corporation of $1,917 and $99,904, respectively, for reimbursement of direct
expenses and management fees associated with the coordination of partnership
activities. During 1996, 1995 and 1994, Repligen Partners made payments to
Repligen Corporation of approximately $603,000, $6,160,000 and $11,500,000,
respectively, for research and development activities, management fees,
interest due under the Development Agreement and direct expenses incurred on
behalf of Repligen Partners.
Until the termination of the research program and the marketing program
in March 1996, the primary use of Repligen Partners' capital resources had
been to fund the research program. From its inception to December 31, 1998,
Repligen Partners incurred aggregate expenses of approximately $35,713,000
versus approximately $38,645,000 anticipated at the inception of Repligen
Partners. The difference is due primarily to a change in the manufacturing
process of rPF4 and the need to conduct multiple clinical trials, offset by
reductions in research and development activities over the 1995 and 1996
fiscal years and Repligen Corporation's decision to absorb $1,665,000 of
research and development costs related to the research program, which was
impacted in part by Repligen Partners' inability to collect all partner's
contributions.
In March, 1996, Repligen Partners anticipated that an additional
investment of at least $50,000,000 would be needed to complete the remainder
of the research program, to obtain all FDA and other regulatory approvals and
to commence sales of any rPF4-based products. In March 1996, Repligen
Corporation advised Repligen Partners that it did not currently have nor did
it anticipate generating funds sufficient in aggregate amount to finance the
remainder of the research program and the marketing program. As a result, the
board of directors of Repligen Development voted to terminate the research
program and the marketing program. See "The Proposed Termination--The
Partnership--Subsequent Developments--Termination of Research and Marketing
Programs".

ANNEX A
FINANCIAL STATEMENTS OF THE PARTNERSHIP
Report of Independent Public Accountants
To Repligen Clinical Partners, L.P. :
We have audited the accompanying balance sheets of Repligen Clinical
Partners, L.P. (a Delaware limited partnership) as of December 31, 1998 and
1997, and the related statements of operations, changes in partners' capital
(deficit), and cash flows for each of the three years in the period ended
December 31, 1998. These financial statements are the responsibility of the
General Partner. 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 Repligen Clinical
Partners, L.P. as of December 31, 1998 and 1997 and the results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1998, in conformity with generally accepted accounting
principles.
The accompanying financial statements have been prepared assuming the
Partnership will continue as a going concern. During 1996 through 1999 the
General Partner was marketing the rPF4-technology for sale to potential third
parties. The Company has been unable to secure a third party buyer.
Accordingly, the General Partner intends to seek the vote of the Limited
Partners to approve the termination of the Limited Partnership. These matters
are further discussed in Note 2 to the financial statements. The accompanying
financial statements do not include any adjustments that might result from the
outcome of this uncertainty.

REPLIGEN CLINICAL PARTNERS, L.P.
NOTES TO FINANCIAL STATEMENTS
(to be updated by AA)
1. Organization
Repligen Clinical Partners, L.P. (Repligen Partners) is a Delaware
Limited Partnership that was organized on January 9, 1992, and was formed to
fund the further development of Repligen Corporation's (Repligen) recombinant
platelet factor-4 (rPF4) protein. Repligen Partners is managed by its general
partner, Repligen Development Corporation. In connection with the formation of
Repligen Partners, Repligen granted to Repligen Partners an exclusive license
to all technology and know-how related to the manufacture, use and sale of
rPF4 in the United States, Canada and Europe.
On February 28, 1992, Repligen Partners completed a private placement of
(i) 900 Class A units, each unit (a Class A Unit) consisting of one Class A
limited partnership interest in Repligen Partners and a warrant to purchase
2,900 shares of Repligen Common Stock, and (ii) one Class B unit (the Class B
Unit) consisting of one Class B limited partnership interest in Repligen
Partners and a warrant to purchase 5,800 shares of Repligen Common Stock. In
addition, Repligen issued warrants to the sales agent of the private placement
and an affiliate of the agent to purchase 75,050 shares and 13,300 shares,
respectively, of Repligen Common Stock. The private placement resulted in net
proceeds of approximately $40,312,000 in cash and non-interest bearing notes
receivable from partners, of which approximately $35,346,000 has been paid by
the Partners and approximately $4,966,000 has been written off due to
defaulted units.
In March 1996, Repligen advised Repligen Partners that it did not
currently have nor did it anticipate generating funds sufficient in aggregate
amount to finance the remainder of the Research Program and the Marketing
Program. Repligen Partners has incurred significant operating losses since
inception and the Board of Directors of Repligen Development of Repligen
Partners determined that, without additional financing from Repligen or one or
more third parties, Repligen Partners would not have sufficient funding to
complete the Research Program and Marketing Program. As a result, the Board of
Directors of Repligen Development of Repligen Partners voted to terminate the
Research Program and the Marketing Program, and directed that Repligen
Development market the rPF4-related technology to prospective third-party
purchasers, licensors, or joint-venture partners.
During 1996 and 1997, the Partnership introduced the rPF4-technology for
possible acquisition to numerous pharmaceutical and biotechnology companies
and continued the presentation of the Partnership's technology to interested
parties who had already initiated preliminary review. Furthermore, during 1998
and 1999, the Partnership continued to market the rPF4-technology to a limited
number of parties who were in an advanced stage of review. In the absence of a
decision to acquire the Partnership's assets by one of the parties that has
completed an advanced review, the General Partner intends to seek the vote of
the Limited Partners to approve the termination of the Limited Partnership.
2. Business Operations
The Partnership is no longer devoting its efforts toward marketing the
rPF4 technology to prospective third-party purchasers, licensors or
joint-venture partners. The Partnership has limited its recent efforts to
marketing the rPF4-technology to a few prospective third-party purchasers who
engaged in an advanced review. The General Partner intends to terminate the
Limited Partnership by seeking a vote of the Limited Partners. At December 31,
1998, the Partnership has negative net worth and no financial resources. A
Limited Partner has agreed to make an additional capital contribution to pay
all outstanding liabilities of the Partnership at December 31, 1998.
F-6
<PAGE>
3. Summary of Significant Accounting Policies
(a) Basis of Presentation
The Partnership prepares its financial statements on the accrual basis of
accounting. The financial statements include only those assets, liabilities,
revenues and expenses which relate to the business of Repligen Partners.
Research and development costs were expended as incurred under the agreements
with Repligen.
(b) Cash and Cash Equivalents
Cash equivalents are short-term, highly liquid investments with original
maturities of less than three months at the time of acquisition.
(c) Income Taxes
The Partnership does not provide for federal or state income taxes,
because no income taxes are payable by Repligen Partners. Partners are liable
for income taxes on their share of Repligen Partners' taxable income, if any.
(d) Management Estimates
The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
periods presented. Actual results could differ from those estimates.
(e) Concentrations of Credit Risk
Financial instruments that subject the Company to significant
concentrations of credit risk consist primarily of cash and cash equivalents.
The Company's cash equivalents are invested in financial instruments with high
credit ratings.
(f) Fair Value of Financial Instruments
The carrying amounts of the Company's cash equivalents approximate fair
value due to the short-term nature of these instruments.
4. Partners' Capital (Deficit)
(a) Partner Contributions:
In connection with the sale of the partnership units discussed in Note 1,
each limited partner agreed to make annual installments evidenced by
non-interest bearing notes to Repligen Partners, commencing on March 15, 1993.
The Partnership has written off all notes receivable relating to the limited
partnership units which were foreclosed for failure to pay either the second,
third or fourth installments. As of December 31, 1998 and 1997, 711 1/2 of the
original 900 Class A Units were outstanding.
(b) Partnership Allocation and Distribution:
Profits or losses for each fiscal year of the partnership are allocated
1% to Repligen Development and 99% to the limited partners until each Class A
limited partner has received distributions equal to its capital contribution,
as defined. Profits or losses allocated to the limited partners are allocated
pro rata in accordance with their adjusted capital contributions, as defined.
F-7
<PAGE>
Upon each Class A limited partner receiving distributions equal to their
capital contributions, Repligen Development will be entitled to 1% of the
profits or losses, and the limited partners will be entitled to 99% of the
profits or losses. The allocation to the limited partners shall be allocated
among the limited partners as follows: 5% to the Class B limited partner and
95% among the Class A limited partners pro rata in accordance with their
adjusted capital contributions, as defined.
Losses in excess of the limited partners' capital contribution
obligations are allocated to the General Partner. At December 31, 1998, the
losses in-excess of capital contributions has been allocated to the limited
partner who has committed to funding such losses.
5. Related Party Transactions
Under the Development Agreement (the "Development Agreement") with
Repligen, Repligen Partners reimbursed Repligen for research and development
costs incurred under the Development Agreement, plus paid a management fee
equal to 10% of such costs. During 1998, 1997 and 1996 Repligen Partners
incurred research and development expenses of approximately $0, $9,000 and
$422,000, respectively and general and administrative expenses of
approximately $62,000, $98,000 and $237,000, respectively related to the
management fee due under the Development Agreement. Approximately $500 of
these amounts has been included in amounts due to Repligen Corporation in the
accompanying 1997 balance sheet.
In connection with the initial capitalization of Repligen Partners,
Repligen issued warrants to purchase Repligen Common Stock to the limited
partners of Repligen Partners (the Original Warrants). In June 1994, Repligen
completed an exchange pursuant to which a majority of the holders of Original
Warrants exchanged their Original Warrants for new warrants ( the Exchange
Warrants). Subsequently, in March 1995, Repligen offered to modify the
majority of the remaining Original Warrants and the Exchange Warrants. Each
holder of an outstanding warrant who was not in default under its obligations
to Repligen Partners was free to accept or reject such modifications. As of
December 31, 1996, holders of 620 of the 711 1/2 non-defaulted Class A Units
had accepted the modifications, and there were issued and outstanding Original
Warrants to purchase 75,400 shares of Repligen Common Stock, modified Original
Warrants to purchase 163,850 shares of Repligen Common Stock, Exchange
Warrants to purchase 189,950 shares of Repligen Common Stock and modified
Exchange Warrants to purchase 1,653,250 shares of Repligen Common Stock.
