                       BYLAWS OF BIO-BRIDGE SCIENCE, INC.

                      ====================================

                         ARTICLE I -- CORPORATE OFFICES

     1.1  REGISTERED OFFICE.

     The  registered  office of Bio-Bridge  Science,  Inc. shall be fixed in the
corporation's certificate of incorporation, as the same may be amended from time
to time.

     1.2  OTHER OFFICES.

     The  corporation's  Board  of  Directors  (the  "Board")  may at  any  time
establish  other  offices  at any  place or  places  where  the  corporation  is
qualified to do business.

                     ARTICLE II -- MEETINGS OF STOCKHOLDERS

     2.1  PLACE OF MEETINGS.

     Meetings of stockholders shall be held at any place,  within or outside the
State  of  Delaware,  designated  by the  Board.  The  Board  may,  in its  sole
discretion,  determine that a meeting of  stockholders  shall not be held at any
place,  but may  instead  be held  solely  by means of remote  communication  as
authorized by Section  211(a)(2) of the Delaware  General  Corporation  Law (the
"DGCL"). In the absence of any such designation or determination,  stockholders'
meetings shall be held at the corporation's principal executive office.

     2.2  ANNUAL MEETING.

     The annual meeting of stockholders shall be held each year. The Board shall
designate  the date and  time of the  annual  meeting.  In the  absence  of such
designation  the  annual  meeting  of  stockholders  shall be held on the second
Tuesday of May of each year at 10:00 a.m. However,  if such day falls on a legal
holiday,  then the meeting  shall be held at the same time and place on the next
succeeding  business day. At the annual meeting,  directors shall be elected and
any other proper business may be transacted.

     2.3  SPECIAL MEETING.

     A  special  meeting  of the  stockholders  may be called at any time by the
Board,  chairperson of the Board,  chief executive  officer or president (in the
absence of a chief  executive  officer) or by one or more  stockholders  holding
shares in the aggregate  entitled to cast not less than 10% of the votes at that
meeting.

     If any person(s) other than the Board calls a special meeting,  the request
shall:

          (i) be in writing;

          (ii)  specify the time of such  meeting and the general  nature of the
     business proposed to be transacted; and



          (iii)  be  delivered  personally  or  sent  by  registered  mail or by
     facsimile transmission to the chairperson of the Board, the chief executive
     officer, the president (in the absence of a chief executive officer) or the
     secretary of the corporation.

     The  officer(s)  receiving  the request  shall cause  notice to be promptly
given to the stockholders  entitled to vote at such meeting,  in accordance with
the  provisions of Sections 2.4 and 2.5 of these bylaws,  that a meeting will be
held at the time  requested  by the person or persons  calling the  meeting.  No
business  may be  transacted  at such  special  meeting  other than the business
specified in such notice to stockholders. Nothing contained in this paragraph of
this Section 2.3 shall be construed as limiting,  fixing,  or affecting the time
when a meeting of stockholders called by action of the Board may be held.

     2.4  NOTICE OF STOCKHOLDERS' MEETINGS.

     All notices of meetings of stockholders shall be sent or otherwise given in
accordance  with either Section 2.5 or Section 8.1 of these bylaws not less than
10 nor more than 60 days  before  the date of the  meeting  to each  stockholder
entitled to vote at such meeting.  The notice shall  specify the place,  if any,
date and hour of the  meeting,  the means of remote  communication,  if any,  by
which  stockholders  and proxy holders may be deemed to be present in person and
vote at such  meeting,  and,  in the case of a special  meeting,  the purpose or
purposes for which the meeting is called.

     2.5  MANNER OF GIVING NOTICE; AFFIDAVIT OF NOTICE.

     Notice of any meeting of stockholders shall be given:

          (i) if mailed,  when  deposited  in the United  States  mail,  postage
     prepaid, directed to the stockholder at his or her address as it appears on
     the  corporation's  records;  or

          (ii) if electronically transmitted as provided in Section 8.1 of these
     bylaws.

     An affidavit of the secretary or an assistant  secretary of the corporation
or of the transfer agent or any other agent of the  corporation  that the notice
has been given by mail or by a form of electronic  transmission,  as applicable,
shall,  in the  absence of fraud,  be prima facie  evidence of the facts  stated
therein.

     2.6  QUORUM.

     The holders of a majority of the stock issued and  outstanding and entitled
to vote,  present in person or represented by proxy,  shall  constitute a quorum
for the  transaction  of  business  at all  meetings  of the  stockholders.  If,
however,  such  quorum is not  present  or  represented  at any  meeting  of the
stockholders,  then  either  (i) the  chairperson  of the  meeting,  or (ii) the
stockholders  entitled to vote at the meeting,  present in person or represented
by proxy,  shall have power to adjourn  the meeting  from time to time,  without
notice  other than  announcement  at the  meeting,  until a quorum is present or
represented.  At  such  adjourned  meeting  at  which a  quorum  is  present  or
represented,  any business may be transacted  that might have been transacted at
the meeting as originally noticed.

     2.7  ADJOURNED MEETING; NOTICE.

     When a meeting is adjourned  to another time or place,  unless these bylaws
otherwise  require,  notice  need not be given of the  adjourned  meeting if the
time,  place if any thereof,  and the means of remote  communications  if any by
which  stockholders  and proxy holders may be deemed to be present in person and
vote at such  adjourned  meeting  are  announced  at the  meeting  at which  the
adjournment  is  taken.  At the  continuation  of  the  adjourned  meeting,  the
corporation  may transact any business  which might have been  transacted at the
original  meeting.  If the adjournment is for more than 30 days, or if after the
adjournment  a new record date is fixed for the adjourned  meeting,  a notice of
the adjourned  meeting shall be given to each  stockholder of record entitled to
vote at the meeting.



                                      -2-


     2.8  CONDUCT OF BUSINESS.

     The chairperson of any meeting of stockholders shall determine the order of
business and the  procedure at the meeting,  including  such  regulation  of the
manner of voting and the conduct of business.

     2.9  VOTING.

     The stockholders  entitled to vote at any meeting of stockholders  shall be
determined  in accordance  with the  provisions of Section 2.11 of these bylaws,
subject to Section 217 (relating to voting rights of  fiduciaries,  pledgors and
joint  owners of stock) and Section  218  (relating  to voting  trusts and other
voting agreements) of the DGCL.

     Except as may be otherwise  provided in the certificate of incorporation or
these bylaws,  each stockholder  shall be entitled to one vote for each share of
capital stock held by such stockholder.

     2.10 STOCKHOLDER ACTION BY WRITTEN CONSENT WITHOUT A MEETING.

     Unless otherwise  provided in the certificate of incorporation,  any action
required  by  the  DGCL  to be  taken  at  any  annual  or  special  meeting  of
stockholders of a corporation, or any action which may be taken at any annual or
special meeting of such  stockholders,  may be taken without a meeting,  without
prior notice,  and without a vote, if a consent or consents in writing,  setting
forth the action so taken,  shall be signed by 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
thereon were present and voted.

     Prompt  notice of the taking of the corporate  action  without a meeting by
less than unanimous  written  consent shall be given to those  stockholders  who
have not  consented  in  writing  and who,  if the  action  had been  taken at a
meeting,  would have been  entitled  to notice of the meeting if the record date
for such meeting had been the date that written  consents signed by a sufficient
number of  holders to take the  action  were  delivered  to the  corporation  as
provided  in Section  228 of the DGCL.  In the event  that the  action  which is
consented to is such as would have  required the filing of a  certificate  under
any provision of the DGCL, if such action had been voted on by stockholders at a
meeting thereof, the certificate filed under such provision shall state, in lieu
of any statement required by such provision concerning any vote of stockholders,
that written consent has been given in accordance with Section 228 of the DGCL.

     2.11 RECORD DATE FOR STOCKHOLDER NOTICE; VOTING; GIVING CONSENTS.

     In order that the  corporation may determine the  stockholders  entitled to
notice of or to vote at any meeting of stockholders or any adjournment  thereof,
or  entitled  to  receive  payment  of any  dividend  or other  distribution  or
allotment  of any rights,  or entitled to exercise  any rights in respect of any
change,  conversion  or exchange of stock or for the purpose of any other lawful
action,  the Board may fix, in advance,  a record date,  which record date shall
not precede the date on which the  resolution  fixing the record date is adopted
and which  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 such action.



                                      -3-


     If the Board does not so fix a record date:

          (i) 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 next  preceding the day on which notice is given,  or, if notice
     is waived,  at the close of business on the day next  preceding  the day on
     which the meeting is held.

          (ii) 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 is  necessary,  shall be the day on which  the  first
     written consent is expressed.

          (iii)  The  record  date for  determining  stockholders  for any other
     purpose  shall be at the  close of  business  on the day on which the Board
     adopts the resolution relating thereto.

     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 may fix a new record date for the  adjourned
meeting.

     2.12 PROXIES.

     Each  stockholder  entitled  to vote at a  meeting  of  stockholders  or to
express consent or dissent to corporate  action in writing without a meeting may
authorize  another  person  or  persons  to act for  such  stockholder  by proxy
authorized  by an instrument  in writing or by a  transmission  permitted by law
filed in accordance with the procedure  established for the meeting, but no such
proxy shall be voted or acted upon after  three years from its date,  unless the
proxy provides for a longer period.  The  revocability of a proxy that states on
its face that it is  irrevocable  shall be governed by the provisions of Section
212 of the DGCL.

     2.13 LIST OF STOCKHOLDERS ENTITLED TO VOTE.

     The officer  who has charge of the stock  ledger of the  corporation  shall
prepare  and make,  at least 10 days before  every  meeting of  stockholders,  a
complete list of the stockholders  entitled to vote at the meeting,  arranged in
alphabetical  order,  and showing the address of each stockholder and the number
of shares registered in the name of each stockholder.  The corporation shall not
be required to include  electronic  mail addresses or other  electronic  contact
information  on such  list.  Such list shall be open to the  examination  of any
stockholder,  for any purpose germane to the meeting for a period of at least 10
days prior to the meeting:  (i) on a reasonably  accessible  electronic network,
provided that the  information  required to gain access to such list is provided
with the notice of the meeting,  or (ii) during ordinary  business hours, at the
corporation's  principal  executive  office.  In the event that the  corporation
determines to make the list available on an electronic network,  the corporation
may take reasonable  steps to ensure that such  information is available only to
stockholders of the corporation.  If the meeting is to be held at a place,  then
the list shall be produced and kept at the time and place of the meeting  during
the whole time thereof,  and may be inspected by any stockholder who is present.
If the meeting is to be held solely by means of remote  communication,  then the
list shall also be open to the examination of any  stockholder  during the whole
time of the  meeting on a  reasonably  accessible  electronic  network,  and the
information  required to access  such list shall be provided  with the notice of
the  meeting.  Such list  shall  presumptively  determine  the  identity  of the
stockholders  entitled  to vote at the  meeting and the number of shares held by
each of them.


                                      -4-


                            ARTICLE III -- DIRECTORS

     3.1  POWERS.

     Subject  to  the  provisions  of  the  DGCL  and  any  limitations  in  the
certificate of  incorporation  or these bylaws relating to action required to be
approved by the  stockholders  or by the  outstanding  shares,  the business and
affairs of the  corporation  shall be managed and all corporate  powers shall be
exercised by or under the direction of the Board.

     3.2  NUMBER OF DIRECTORS.

     The authorized number of directors shall be determined from time to time by
resolution  of the  Board,  provided  the Board  shall  consist  of at least one
member. No reduction of the authorized number of directors shall have the effect
of removing any director before that director's term of office expires.

     3.3  ELECTION, QUALIFICATION AND TERM OF OFFICE OF DIRECTORS.

     Except as  provided  in Section  3.4 of these  bylaws,  directors  shall be
elected at each annual  meeting of  stockholders  to hold office  until the next
annual  meeting.  Directors need not be  stockholders  unless so required by the
certificate of incorporation  or these bylaws.  The certificate of incorporation
or these bylaws may prescribe other qualifications for directors. Each director,
including a director  elected to fill a vacancy,  shall hold  office  until such
director's  successor is elected and qualified or until such director's  earlier
death, resignation or removal.

     All elections of directors  shall be by written  ballot,  unless  otherwise
provided in the certificate of  incorporation;  if authorized by the Board, such
requirement  of a written  ballot shall be  satisfied  by a ballot  submitted by
electronic transmission,  provided that any such electronic transmission must be
either  set  forth  or be  submitted  with  information  from  which  it  can be
determined  that the electronic  transmission  authorized by the  stockholder or
proxy holder.

     3.4  RESIGNATION AND VACANCIES.

     Any  director  may  resign at any time upon  notice  given in writing or by
electronic  transmission  to the  corporation.  When  one or more  directors  so
resigns and the  resignation  is  effective  at a future date, a majority of the
directors then in office, including those who have so resigned, shall have power
to fill such  vacancy or  vacancies,  the vote  thereon to take effect when such
resignation or resignations shall become effective,  and each director so chosen
shall hold office as provided in this section in the filling of other vacancies.

     Unless  otherwise  provided in the  certificate of  incorporation  or these
bylaws:

          (i)  Vacancies  and newly  created  directorships  resulting  from any
     increase  in the  authorized  number  of  directors  elected  by all of the
     stockholders  having the right to vote as a single class may be filled by a
     majority of the directors then in office,  although less than a quorum,  or
     by a sole remaining director.

          (ii)  Whenever  the holders of any class or classes of stock or series
     thereof are entitled to elect one or more  directors by the  provisions  of
     the certificate of incorporation, vacancies and newly created directorships
     of such  class or  classes  or series  may be filled by a  majority  of the
     directors  elected  by such  class or  classes  or series  thereof  then in
     office, or by a sole remaining director so elected.


                                      -5-


     If at any time,  by  reason of death or  resignation  or other  cause,  the
corporation  should  have no  directors  in  office,  then  any  officer  or any
stockholder or an executor, administrator, trustee or guardian of a stockholder,
or other fiduciary  entrusted with like  responsibility for the person or estate
of a stockholder,  may call a special meeting of stockholders in accordance with
the provisions of the certificate of incorporation or these bylaws, or may apply
to the Court of Chancery for a decree summarily ordering an election as provided
in Section 211 of the DGCL.

     If, at the time of filling any vacancy or any newly  created  directorship,
the directors then in office  constitute less than a majority of the whole Board
(as  constituted  immediately  prior to any such  increase),  then the  Court of
Chancery may, upon  application of any  stockholder or  stockholders  holding at
least 10% of the total number of the shares at the time  outstanding  having the
right to vote for such directors, summarily order an election to be held to fill
any such vacancies or newly created  directorships,  or to replace the directors
chosen by the directors  then in office as aforesaid,  which  election  shall be
governed by the provisions of Section 211 of the DGCL as far as applicable.

     3.5  PLACE OF MEETINGS; MEETINGS BY TELEPHONE.

     The Board may hold  meetings,  both regular and special,  either  within or
outside the State of Delaware.

     Unless  otherwise  restricted by the certificate of  incorporation or these

     The  shares  of the  corporation  shall  be  represented  by  certificates,
provided that the Board may provide by resolution  or  resolutions  that some or
all of any or all classes or series of its stock shall be uncertificated shares.
Any such resolution shall not apply to shares represented by a certificate until
such certificate is surrendered to the corporation. Notwithstanding the adoption
of such a  resolution  by the  Board,  every  holder  of  stock  represented  by
certificates  and upon request  every holder of  uncertificated  shares shall be
entitled to have a certificate  signed by, or in the name of the  corporation by
the  chairperson  or   vice-chairperson  of  the  Board,  or  the  president  or
vice-president, and by the treasurer or an assistant treasurer, or the secretary
or an assistant secretary of such corporation  representing the number of shares
registered in certificate  form. Any or all of the signatures on the certificate
may be a facsimile.  In case any officer,  transfer  agent or registrar  who has
signed or whose  facsimile  signature  has been  placed upon a  certificate  has
ceased to be such officer,  transfer agent or registrar  before such certificate
is issued,  it may be issued by the  corporation  with the same  effect as if he
were such officer, transfer agent or registrar at the date of issue.

     The  corporation  may issue  the whole or any part of its  shares as partly
paid and  subject  to call for the  remainder  of the  consideration  to be paid
therefor.  Upon the face or back of each stock  certificate  issued to represent
any such partly paid shares,  upon the books and records of the  corporation  in
the  case  of  uncertificated  partly  paid  shares,  the  total  amount  of the
consideration  to be paid  therefor and the amount paid thereon shall be stated.
Upon the declaration of any dividend on fully paid shares, the corporation shall
declare a dividend upon partly paid shares of the same class,  but only upon the
basis of the percentage of the consideration actually paid thereon.

     7.4  SPECIAL DESIGNATION ON CERTIFICATES.

preferences, and the relative,  participating,  optional or other special rights
of each class of stock or series thereof and the qualifications,  limitations or
restrictions  of such  preferences  and/or  rights shall be set forth in full or
summarized on the face or back of the  certificate  that the  corporation  shall
issue to  represent  such  class or series of stock;  provided,  however,  that,
except  as  otherwise  provided  in  Section  202 of the  DGCL,  in  lieu of the
foregoing  requirements  there  may be set  forth  on the  face  or  back of the
certificate  that the corporation  shall issue to represent such class or series
of stock a statement that the  corporation  will furnish  without charge to each
stockholder who so requests the powers, the designations,  the preferences,  and
the relative,  participating,  optional or other special rights of each class of
stock or series thereof and the  qualifications,  limitations or restrictions of
such preferences and/or rights.

         Except as provided in this Section 7.5, no new  certificates for shares
shall be issued to replace a previously issued  certificate unless the latter is
surrendered to the  corporation  and cancelled at the same time. The corporation
may issue a new  certificate of stock or  uncertificated  shares in the place of
any certificate  theretofore  issued by it, alleged to have been lost, stolen or
destroyed,  and the  corporation  may require  the owner of the lost,  stolen or
destroyed  certificate,  or such  owner's  legal  representative,  to  give  the
corporation a bond sufficient to indemnify it against any claim that may be made
against it on account of the  alleged  loss,  theft or  destruction  of any such
certificate or the issuance of such new  certificate or  uncertificated  shares.

     7.6  CONSTRUCTION; DEFINITIONS.

shares of the corporation's capital stock.

     The  Board  may  set  apart  out of any of  the  funds  of the  corporation
available  for  dividends a reserve or reserves  for any proper  purpose and may

any one or more classes owned by such  stockholders in any manner not prohibited
by the DGCL.

     provided by the laws of Delaware.

     7.13 WAIVER OF NOTICE.

     Whenever  notice is required to be given under any  provision  of the DGCL,
the certificate of incorporation  or these bylaws,  a written waiver,  signed by
the person  entitled to notice,  or a waiver by electronic  transmission  by the
person  entitled  to notice,  whether  before or after the time of the event for
which notice is to be given, shall be deemed equivalent to notice. Attendance of
a person  at a meeting  shall  constitute  a waiver  of notice of such  meeting,
except when the person 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 or any waiver by
electronic  transmission  unless so required by the certificate of incorporation
or these bylaws.

               ARTICLE VIII -- NOTICE BY ELECTRONIC TRANSMISSION

     8.1  NOTICE BY ELECTRONIC TRANSMISSION.

     Without  limiting  the  manner  by  which  notice  otherwise  may be  given
effectively  to   stockholders   pursuant  to  the  DGCL,  the   certificate  of
incorporation  or  these  bylaws,  any  notice  to  stockholders  given  by  the
corporation under any provision of the DGCL, the certificate of incorporation or
these bylaws shall be  effective if given by a form of  electronic  transmission
consented to by the  stockholder  to whom the notice is given.  Any such consent
shall be revocable by the stockholder by written notice to the corporation.  Any
such  consent  shall be deemed  revoked  if:


                                      -15-

          (i) the  corporation  is unable to deliver by electronic  transmission
     two  consecutive  notices given by the  corporation in accordance with such
     consent; and

          (ii) such  inability  becomes  known to the  secretary or an assistant
     secretary  of the  corporation  or to the transfer  agent,  or other person
     responsible for the giving of notice.

However,  the inadvertent  failure to treat such inability as a revocation shall
not invalidate any meeting or other action.

     Any notice given pursuant to the preceding paragraph shall be deemed given:

          (i) if by facsimile  telecommunication,  when  directed to a number at
     which the stockholder has consented to receive notice;

          (ii) if by  electronic  mail,  when  directed  to an  electronic  mail
     address at which the stockholder has consented to receive notice;

          (iii) if by a posting on an electronic  network together with separate
     notice to the stockholder of such specific  posting,  upon the later of (A)
     such posting and (B) the giving of such separate notice; and

          (iv) if by any other form of electronic transmission, when directed to
     the stockholder.

     An affidavit of the secretary or an assistant  secretary or of the transfer
agent or other agent of the corporation that the notice has been given by a form
of  electronic  transmission  shall,  in the  absence of fraud,  be prima  facie
evidence of the facts stated therein.

     8.2  DEFINITION OF ELECTRONIC TRANSMISSION.

     An "electronic transmission" means any form of communication,  not directly
involving the physical  transmission of paper, that creates a record that may be
retained,  retrieved,  and  reviewed  by a  recipient  thereof,  and that may be
directly  reproduced  in paper form by such a  recipient  through  an  automated
process.

     8.3  INAPPLICABILITY.

     Notice by a form of  electronic  transmission  shall not apply to  Sections
164, 296, 311, 312 or 324 of the DGCL.

                            ARTICLE IX -- AMENDMENTS

         These  bylaws may be adopted,  amended or repealed by the  stockholders
entitled  to  vote.  However,   the  corporation  may,  in  its  certificate  of
incorporation,  confer  the power to  adopt,  amend or  repeal  bylaws  upon the
directors.  The fact that such power has been so  conferred  upon the  directors
shall not divest the  stockholders of the power, nor limit their power to adopt,
amend or repeal bylaws.
