                          AMENDED AND RESTATED BY-LAWS

                                       OF

                              REPLIGEN CORPORATION


                                    ARTICLE I

                                  STOCKHOLDERS

      SECTION 1. Place of Meetings. All meetings of stockholders shall be held
at such place within or without the State of Delaware as may be designated from
time to time by the Board of Directors or, if not so designated, at the
principal office of the corporation.

      SECTION 2. Annual Meeting. The annual meeting of stockholders of the
election of directors and the transaction of such other business as may properly
come before the meeting shall be held at 10 a.m. on the last Thursday in July of
each year or on such other date or at such hour as may be specified by
resolution of the Board of Directors. If the date of the annual meeting shall
fall upon a legal holiday at the place of the meeting, the meeting shall be held
at the same hour on the next succeeding business day. If the annual meeting is
not held on the date designated therefor, the directors shall cause the meeting
to be held as soon thereafter as convenient.

      SECTION 3. Special Meetings. Special meetings of the stockholders may be
called at any time by the President, the Chairman, or the Board of Directors, or
by the Secretary or any other officer upon the written request of one or more
stockholders holding of record at least a majority of the outstanding shares of
stock of the corporation entitled to vote at such meeting. Such written request
shall state the purpose or purposes of the proposed meeting. Business transacted
at any special meeting of stockholders shall be limited to matters relating to
the purpose or purposes stated in the notice of meeting.

      SECTION 4. Notice of Meetings. Except where some other notice is required
by law, written notice of each meeting of stockholders, stating the place, date
and hour thereof and the purposes for which the meeting is called, shall be
given by or under the direction of the Secretary, not less than ten nor more
than sixty days before the date fixed for such meeting, to each stockholder
entitled to vote at such meeting of record at the close of business on the day
fixed by the Board of Directors as a record date for the determination of the
stockholders entitled to vote at such meeting or, if not such date has been
fixed, of record at the close of business on the day before the day on which
notice is given. Notice shall be given personally to each stockholder or left at
his or her residence or usual place of business or mailed postage prepaid and
addressed to the stockholder at his or her address as it appears upon the
records of the corporation. In case of the death, absence, incapacity or refusal
of the Secretary, such notice may be given by a person designated either by a
Secretary or by the person or persons calling the



meeting or by the Board of Directors. A waiver of such notice in writing, signed
by the person or persons entitled to said notice, whether before or after the
time stated therein, shall be deemed equivalent to such notice. Attendance of a
person at a meeting of stockholders shall constitute a waiver of notice of such
meeting, except when the stockholder attends a meeting for the express purpose
of objecting, at the beginning of the meeting, to the transaction of any
business because the meeting is not lawfully called or convened. Neither the
business to be transacted at, nor the purpose of, any regular or special meeting
of the stockholders need be specified in any written waiver of notice. Notice of
any meeting of the stockholders shall be deemed to have been given to any person
who may become a stockholder of record after the mailing of such notice and
prior to such meeting. Except as required by statute, notice of any adjourned
meeting of the stockholders shall not be required.

      SECTION 5. Voting List. The officer who has charge of the stock ledger of
the corporation shall prepare and make, at least ten days before every meeting
of stockholders, a complete list of the stockholders, arranged in alphabetical
order, and showing the address of each stockholder and the number of shares
registered in the name of each stockholder. Such list shall be open to the
examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place within the city or other municipality or community where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof, and may be inspected by an stockholder who is
present. The stock ledger shall be the only evidence as to who are the
stockholders entitled to examine the stock ledger, the list required by this
section or the books of the corporation, or to vote at any meeting of
stockholders.

      SECTION 6. Quorum of Stockholders. At any meeting of the stockholders, the
holders of a majority in interest of all stock issued and outstanding and
entitled to vote upon a question to be considered at the meeting, present in
person or represented by proxy, shall constitute a quorum for the consideration
of such question, but a smaller group may adjourn any meeting from time to time.
When a quorum is present at any meeting, a majority of the stock represented
thereat and entitled to vote shall, except where a larger vote is required by
law, by the certificate of incorporation, or by these by-laws, decide any
question brought before such meeting. Any election by stockholders shall be
determined by a plurality of the vote cast by the stockholders entitled to vote
at the election.

      SECTION 7. Proxies and Voting. Each stockholder shall at every meeting of
the stockholders be entitled to one vote in person or by proxy for each share of
the capital stock held of record by such stockholder, but no proxy shall be
voted on after three years from its date, unless said proxy provides for a
longer period. Persons holding stock in a fiduciary capacity shall be entitled
to vote the shares so held, and persons whose stock is pledged shall be entitled
to vote, unless in the transfer by the pledgor on the books of the corporation
the pledgee shall have been expressly empowered to vote thereon, in which case
only the pledgee or the pledgee's proxy may represent said stock and vote
thereon. Shares of the capital stock of the corporation belonging to the
corporation or to another corporation, a majority of whose shares entitled to



vote in the election of directors is owned by the corporation, shall not be
entitled to vote nor counted for quorum purposes.

      SECTION 8. Conduct of Meeting. Meetings of the stockholders shall be
presided over by one of the following officers in the order of seniority and in
present and acting: the Chairman of the Board, if any, the Vice-Chairman of the
Board, if any, the President, a Vice-President, or, if none of the foregoing is
in office and present and acting, a chairman to be chosen by the stockholders.
The Secretary of the corporation, if present, or an Assistant Secretary, shall
act as secretary of every meeting, but if neither the Secretary nor an Assistant
Secretary is present the chairman of the meeting shall appoint a secretary of
the meeting.

      SECTION 9. Action Without Meeting. Any action required or permitted to be
taken at any annual or special meeting of stockholders of the corporation may be
taken without a meeting, without prior notice and without a vote, if a consent
in writing, setting forth the action so taken, is signed by the holders or by
proxy for the holders of outstanding stock having not less than the minimum
number of votes that would be necessary to authorize or take such action at a
meeting at which all shares entitled to vote on such action were present and
voted. Prompt notice of the taking of corporate action without a meeting by less
than unanimous written consent shall be given to those stockholders who have not
consented in writing.

                                   ARTICLE II

                                    DIRECTORS

      SECTION 1. General Powers. The business and affairs of the corporation
shall be managed by or under the direction of a Board of Directors, who may
exercise all of the powers of the corporation which are not by law required to
be exercised by the stockholders. In the event of a vacancy in the Board of
Directors, the remaining directors, except as otherwise provided by law, may
exercise the powers of the full Board until the vacancy is filled.

      SECTION 2. Number; Election; Tenure and Qualification. The initial Board
of Directors shall consist of three persons and shall be elected by the
incorporator. Thereafter, the number of directors which shall constitute the
whole Board shall be fixed by resolution of the stockholders or the Board of
Directors, but in no event shall be less than one. Each director shall be
elected by the stockholders at the annual meeting and all directors shall hold
office until the next annual meeting and until their successors are elected and
qualified, or until their earlier death, resignation or removal. The number of
directors may be increased or decreased by action of the stockholders or the
Board of Directors. Directors need not be stockholders of the corporation.

      SECTION 3. Enlargement of the Board. The number of the Board of Directors
may be increased at any time, such increase to be effective immediately, by
resolution of the stockholders or the Board of Directors.



      SECTION 4. Vacancies. Any vacancy in the Board of Directors, however
occurring, including a vacancy resulting from an enlargement of the Board and an
unfilled vacancy resulting from an enlargement of the Board and an unfilled
vacancy resulting from the removal of any director for cause or without cause,
may be filled by resolution of the Board. A director elected to fill a vacancy
shall hold office until the next annual meeting of stockholders and until his or
her successor is elected and qualified or until his or her earlier death,
resignation or removal. When one or more directors shall resign from the Board,
effective at a future date, the Board, shall have the power to fill such vacancy
or vacancies, the vote thereon to take effect when such resignation or
resignations shall become effective. If at any time there are no directors in
office, then an election of directors may be held in accordance with the General
Corporation Law of the State of Delaware.

      SECTION 5. Resignation. Any director may resign at any time upon written
notice to the corporation. Such resignation shall take effect at the time
specified therein, or if no time is specified, at the time of its receipt by the
President or Secretary.

      SECTION 6. Removal. Except as may otherwise be provided by the General
Corporation Law, any director or the entire Board of Directors may be removed,
with or without cause, at an annual meeting or at a special meeting called for
that purpose, by the holders of a majority of the shares then entitled to vote
at an election of directors. The vacancy or vacancies thus created may be filled
by the stockholders at the meeting held for the purpose of removal.

      SECTION 7. Committees. The Board of Directors may, by resolution or
resolutions passed by a majority of the whole Board of Directors, designate one
or more committees, each committee to consist of two or more directors of the
corporation. The Board of Directors may designate one or more directors as
alternate members of any committee, who may replace any absent or disqualified
member at any meeting of the committee. In the absence or disqualification of
any member of such committee or committees, the member or members thereof
present at any meeting and not disqualified from voting, whether or not such
member or members constitute a quorum, may unanimously appoint another member of
the Board of Directors to act at the meeting in the place of such absent or
disqualified member.

      A majority of all the members of any such committee may fix its rules of
procedure, determine its action and fix the time and place, whether within or
without the State of Delaware, of its meetings and specify what notice thereof,
if any, shall be given, unless the Board of Directors shall otherwise by
resolution provide. The Board of Directors shall have the power to change the
members of any such committee at any time, to fill vacancies therein and to
discharge any such committee, either with or without cause, at any time.

      Any such committee, unless otherwise provided in the resolution of the
Board of Directors, or in these by-laws, shall have and may exercise all the
powers and authority of the Board of Directors in the management of the business
and affairs of the corporation, and may authorize the seal of the corporation to
be affixed to all papers which may require it; but no such committee shall have
such power or authority in reference to amending the certificate of
incorporation, adopting an agreement of merger or consolidation, recommending to
the stockholders the sale, lease or exchange of all or substantially all of the
corporation's property



and assets, recommending a dissolution of the corporation or a revocation of a
dissolution, or amending the by-laws of the corporation, and, unless the
resolution or these by-laws expressly so provide, no such committee shall have
the power or the authority to declare a dividend or to authorize the issuance of
stock.

      Each committee shall keep regular minutes of its meetings and make such
reports as the Board of Directors may from time to time request.

      SECTION 8. Meetings of the Board of Directors. Regular meetings of the
Board of Directors may be held without call or formal notice at such places
either within or without the State of Delaware and at such times as the Board
may by vote form time to time determine. A regular meeting of the Board of
Directors may be held without call or formal notice immediately after and at the
same place as the annual meeting of the stockholders, or any special meeting of
the stockholders at which a Board of Directors is elected.

      Special meetings of the Board of Directors may be held at any place either
within or without the State of Delaware at any time when called by the Chairman
of the Board of Directors, the President, Treasurer, Secretary, or two or more
directors. Reasonable notice of the time and place of a special meeting shall be
given to each director unless such notice is waived by attendance or by written
waiver in the manner provided in these by-laws for waiver of notice of
stockholders. No notice of any adjourned meeting of the Board of Directors shall
be required. In any case it shall be deemed sufficient notice to a director to
send notice by mail at least seventy-two hours, or by telegram at least
forty-eight hours, before the meeting, addressed to such director at his or her
usual or last known business or home address.

      Directors or members of any committee designated by the directors may
participate in a meeting of the Board of Directors or such committee by means of
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other, and participation by
such means shall constitute presence in person at such meeting.

      SECTION 9. Quorum and Voting. A majority of the total number of directors
shall constitute a quorum, except that when a vacancy or vacancies exist in the
Board, a majority of the directors then in office (but not less than one-third
of the total number of the directors) shall constitute a quorum, and except that
a lesser number of directors consisting of a majority of the directors then in
office who are not officers (but not less than one-third of the total number of
directors) may constitute a quorum for the purpose of acting on any matter
relating to the compensation (including fringe benefits) of an officer of the
corporation. A majority of the directors present, whether or not a quorum is
present, may adjourn any meeting from time to time. The vote of a majority of
the directors present at any meeting at which a quorum is present shall be the
act of the Board of Directors, except where a different vote is required or
permitted by law, by the certificate of incorporation, or by these by-laws.

      SECTION 10. Compensation. The Board of Directors may fix fees for their
services and for their membership on committees, and expenses of attendance may
be allowed for attendance at each meeting. Nothing herein contained shall be
construed to preclude any director from



serving the corporation in any other capacity as an officer, agent or otherwise,
and receiving compensation therefor.

      SECTION 11. Action Without Meeting. Any action required or permitted to be
taken at any meeting of the Board of Directors, or of any committee thereof, may
be taken without a meeting, and without notice, if a written consent thereto is
signed by all members of the Board of Directors, or of such committee, as the
case may be, and such written consent is filed with the minutes of proceedings
of the Board of Directors or such committee.

                                   ARTICLE III

President, a Secretary, a Treasurer, and such other officers with such other
titles as the Board of Directors shall determine, including without limitation a
Chairman of the Board, a Vice-Chairman of the Board, and one or more
Vice-Presidents, Assistant Treasurers, or Assistant Secretaries.

      SECTION 2. Election and Term of Office. The officers of the corporation
shall be elected annually by the Board of Directors at its first meeting
following the annual meeting of the stockholders. Each officer shall hold office
until his or her successor is elected and qualified, unless a different term is
specified in the vote electing such officer, or until his or her earlier death,
resignation or removal.

      SECTION 3. Qualification. Unless otherwise provided by resolution of the
Board of Directors, no officer, other than the Chairman or Vice-Chairman of the
Board, need be a director. No officer need be a stockholder. Any number of
offices may be held by the same person, as the directors shall determine, but no
person may hold the offices of President and Secretary simultaneously.

      SECTION 4. Removal. Any officer may be removed, with or without cause, at
any time, by resolution adopted by the Board of Directors.

time as shall be specified therein.

      SECTION 6. Vacancies. The Board of Directors may at any time fill any
vacancy occurring in any office for the unexpired portion of the term and may
leave unfilled for such period as it may determine any office other than those

      SECTION 7. Powers and Duties. The officers of the corporation shall have
such powers and perform such duties as are specified herein and as may be
conferred upon or assigned to them by the Board of Directors, and shall have

Directors are inconsistent therewith.

      SECTION 8. President and Vice-Presidents. The President shall be the chief

stockholders and the Board of Directors unless a Chairman or Vice-Chairman of
the Board is elected by the Board, empowered to preside, and present at such
meeting, shall have general and active management of the business of the
corporation and general supervision of its officers, agents and employees, and
shall see that all orders and resolutions of the Board of Directors are carried
into effect.

      In the absence of the President or in the event of his or her inability or
refusal to act, the Vice-President if any (or in the event there be more than
one Vice-President, the Vice-Presidents in the order designated by the
directors, or in the absence of any designation, then in the order of their
election) shall perform the duties of the President, and when so acting, shall
have all the powers of and be subject to all the restrictions upon the
President. The Board of Directors may assign to any Vice-President the title of
Executive Vice-President, Senior Vice-President or any other title selected by
the Board of Directors.

      SECTION 9. Secretary and Assistant Secretaries. The Secretary shall attend
all meetings of the Board of Directors and of the stockholders and record all

Assistant Secretaries in the order determined by the Board of Directors of if
there be no such determination, then in the order of their election) shall, in

refusal to act, perform the duties and exercise the powers of the Secretary.

      SECTION 10. Treasurer and Assistant Treasurers. The Treasurer shall have
the custody of the corporate funds and securities, shall keep full and accurate
accounts of receipts and disbursements in books belonging to the corporation and

of Directors. The Treasurer shall disburse the funds of the corporation as may
be ordered by the Board of Directors or the President, taking proper vouchers
for such disbursements, and shall render to the President and the Board of
Directors, at its regular meetings, or whenever they may require it, an account

there be no such determination, then in the



order of their election) shall, in the absence of the Treasurer or in the event
of his or her inability or refusal to act, perform the duties and exercise the
powers of the Treasurer.

      SECTION 11. Bonded Officers. The Board of Directors may require any
officer to give the corporation a bond in such sum and with such surety or
sureties as shall be satisfactory to the Board of Directors upon such terms and

                                   ARTICLE IV

                                      STOCK

      SECTION 1. Certificates of Stock. One or more certificates of stock,
signed by the Chairman or Vice-Chairman of the Board of Directors or by the
President or Vice-President and by the Treasurer or an Assistant Treasurer or
the Secretary or an Assistant Secretary, shall be issued to each stockholder
certifying, in the aggregate, the number of shares owned by the stockholder in
the corporation. Any or all signatures on any such certificate may be facsimile.
In case any officer who shall have signed or whose facsimile signature shall
have been placed upon a certificate shall have ceased to be such officer before
such certificate is issued, it may be issued by the corporation with the same
effect as if he were such officer at the date of issue.

      Each certificate for shares of stock which are subject to any restriction
on transfer pursuant to the certificate of incorporation, the by-laws,
applicable securities laws, or any agreement among any number of shareholders or
among such holders and the corporation shall have conspicuously noted on the
face or back of the certificate either the full text of the restriction or a
statement of the existence of such restriction.

      SECTION 2. Transfer of Share of Stock. Subject to the restrictions, if
any, stated or noted on the stock certificates, shares of stock may be
transferred on the books of the corporation by the surrender to the corporation
or its transfer agent of the certificate representing such shares properly
endorsed or accompanied by a written assignment or power of attorney properly
executed, and with such proof of authority or the authenticity of signature as
the corporation or its transfer agent may reasonably require. The corporation
shall be entitled to treat the record holder of stock as shown on its books as
the owner of such stock for all purposes, including the payment of dividends and
the right to vote with respect to that stock, regardless of any transfer, pledge
or other disposition of that stock, until the shares have been transferred on
the books of the corporation in accordance with the requirements of these
by-laws.



      SECTION 3. Lost Certificates. A new certificate of stock may be issued in
the place of any certificate theretofore issued by the corporation and alleged
to have been lost, stolen, destroyed, or mutilated, upon such terms in
conformity with law as the Board of Directors shall prescribe. The directors
may, in their discretion, require the owner of the lost, stolen, destroyed or
mutilated certificate, or the owner's legal representatives, to give the
corporation a bond, in such sum as they may direct, to indemnify the corporation
against any claim that may be made against it on account of the alleged loss,
theft, destruction or mutilation of any such certificate, or the issuance of any
such new certificate.

      SECTION 4. Record Date. The Board of Directors may fix in advance a record
date for the determination of the stockholders entitled to notice of or to vote
at any meeting of stockholders or to express consent to corporate action in
writing without a meeting, or entitled to receive payment of any dividend or
other distribution or allotment of any rights in respect of any change,
conversion or exchange of stock, or for the purpose of any other lawful action.
Such record date shall not be more than 60 nor less than 10 days before the date
of such meeting, nor more than 60 days prior to any other action to which such
record date relates.

      If no record date is fixed, the record date for determining stockholders
entitled to notice of or to vote at a meeting of stockholders shall be at the
close of business on the day before the day on which notice is given, or, if
notice is waived at the close of business on the day before the day on which the
meeting is held. The record date for determining stockholders entitled to
express consent to corporate action in writing without a meeting, when no prior
action by the Board of Directors is necessary, shall be the day on which the
first written consent is expressed. The record date for determining stockholders
for any other purpose shall be at the close of business on the day on which the
Board of Directors adopts the resolution relating to such purpose.

      A determination of stockholders of record entitled to notice of or to vote
at a meeting of stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board of Directors may fix a new record date for the
adjourned meeting.

      SECTION 5. Fractional Share Interests. The corporation may, but shall not
be required to, issue fractions of a share. If the corporation does not issue
fractions of a share, it shall (1) arrange for the disposition of fractional
interests by those entitled thereto, (2) pay in cash the fair value of fractions
are determined, or (3) issue scrip or warrants in registered or bearer form
which shall entitle the holder to receive a certificate for a full share upon
the surrender of such scrip or warrants aggregating a full share. A certificate
for a fractional share shall, but scrip or warrants shall not unless otherwise
provided therein, entitle the holder to exercise voting rights, to receive
dividends thereon, and to participate in any of the assets of the corporation in
the event of liquidation. The Board of Directors may cause scrip or warrants to
be issued subject to the conditions that they shall become void if not exchanged
for certificates representing full shares before a specified date, or subject to
the conditions that the shares for which scrip or warrants are exchangeable may
be sold by the corporation and the proceeds thereof distributed to the holders
of scrip or warrants, or subject to any other conditions which the Board of
Directors may impose.



      SECTION 6. Dividends. Subject to the provisions of the certificate of
incorporation, the Board of Directors may, out of funds legally available
therefor, at any regular or special meeting, declare dividends upon the common
stock of the corporation as and when they deem expedient.

permitted by the General Corporation Law of the State of Delaware, as amended
from time to time, and the certificate of incorporation, indemnify each person

      SECTION 2. Insurance. The corporation shall have power to purchase and
maintain insurance on behalf of any person who is or was a director, officer,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against such person and incurred by such person in any capacity or
arising out of such person's status as such, whether or not the corporation
would have the power to indemnify such person against such liability under the
provisions of the General Corporation Law of the State of Delaware.

                                   ARTICLE VI

                               GENERAL PROVISIONS

by the Board of Directors, the fiscal year of the corporation shall begin on the
first day of April and end on the last day of March.

      SECTION 2. Corporate Seal. The corporate seal shall be in such form as
shall be approved by the Board of Directors. The Secretary shall be the
custodian of the seal. The Board of Directors may authorize a duplicate seal to
be kept and used by any other officer.

      SECTION 3. Certificate of Incorporation. All references in these by-laws
to the certificate of incorporation shall be deemed to refer to the certificate
of incorporation of the corporation, as in effect from time to time.

      SECTION 4. Execution of Instruments. The President, any Vice-President, or
the Treasurer shall have power to execute and deliver on behalf and in the name
of the corporation any instrument requiring the signature of an officer of the
corporation, including deeds, contracts, mortgages, bonds, notes, debentures,
checks, drafts, and other orders for the payment of money. In addition, the
Board of Directors may expressly delegate such powers to any other officer or
agent of the corporation.

      SECTION 5. Voting of Securities. Except as the directors may otherwise
designate, the President or Treasurer may waive notice of, and act as, or
appoint any person or persons to act as, proxy or attorney-in-fact for this
corporation (with or without power of substitution) at any meeting of
stockholders or shareholders of any other corporation or organization the
securities of which may be held by this corporation.



      SECTION 6. Evidence of Authority. A certificate by the Secretary, or an
Assistant Secretary, or a temporary secretary, as to any action taken by the
stockholders, directors, a committee or any officer or representative of the
corporation shall, as to all persons who rely on the certificate in good faith,
be conclusive evidence of that action.

      SECTION 7. Transactions with Interested Parties. No contract or
transaction between the corporation and one or more of the directors or
officers, or between the corporation and any other corporation, partnership,
association, or other organization in which one or more of the directors or
officers are directors or officers, or have a financial interest, shall be void
or voidable solely for that reason, or solely because the director or officer is
present at or participates in the meeting of the Board of Directors or a
committee of the Board of Directors which authorizes the contract or transaction
or solely because the vote of any such director is counted for such purpose, if:

            (1) The material facts as to the relationship or interest and as to
