                                                          September 30, 2004

                                  BIONOVO, INC.

         For good and  valuable  consideration  the receipt and  sufficiency  of
which is hereby acknowledged by Bionovo, Inc., a Delaware corporation,  with its
principal  office at 2320 Woolsey Street,  Berkeley,  CA 94705 (the  "Company"),
____________ (the "Holder"), of  ________________________,  subject to the terms
and conditions of this Warrant, is hereby granted the right to purchase,  at the
initial exercise price of $0.6473 per share of common stock, $ par value, of the
Company (the "Common Stock") (the "Initial Exercise Price"),  at any one or more
times after the date hereof until the Expiration Date (as defined below), in the
aggregate,  185,374 shares of Common Stock (the "Shares")  subject to adjustment
as provided in Section 5 hereof.

         This Warrant  initially is  exercisable  at the Initial  Exercise Price
payable in cash (except as provided below),  by certified or official bank check
in New York Clearing  House funds or other form of payment  satisfactory  to the
Company,  subject to  adjustment  as provided in Section 5 hereof.  This Warrant
will  expire on such date (the  "Expiration  Date") as is the earlier of (i) the
fifth  anniversary  of the  Company's  merger  with a company  required  to file
reports  pursuant to Section  13(a) or 15(d) of the  Securities  Exchange Act of
1934, or (ii) September 30, 2011.

         1. Intentionally omitted.

         2. ISSUANCE OF  CERTIFICATES.  Upon the exercise of this  Warrant,  the
issuance  of  certificates  for Shares  underlying  this  Warrant  shall be made
forthwith (and in any event within five days) after the Company's receipt of (i)
written notice hereunder as specified in Section 1 above) and (ii) good funds in
respect of the Purchase  Price (as defined in Section  4(b) hereof)  pursuant to
Section 4 hereof  for the shares so  exercised  and such  certificates  shall be
issued in the name of the Holder hereof.

         3. RESTRICTION ON TRANSFER;  INVESTMENT  REPRESENTATIONS;  REGISTRATION
RIGHTS.

            (a) RESTRICTION ON TRANSFER.  The Holder  acknowledges  that neither
this Warrant nor any Shares  issuable upon exercise  hereof have been registered
under the  Securities  Act of 1933,  as amended (the "Act"),  and neither may be
sold or transferred in whole or in part unless the Holder shall have first given
prior written notice to the Company describing such sale or transfer

<PAGE>

and furnished to the Company an opinion of Company  counsel,  to the effect that
the proposed  sale or transfer may be made without  registration  under the Act;
PROVIDED,  HOWEVER,  that the foregoing  shall not apply if there is in effect a
registration  statement with respect to this Warrant or the Shares issuable upon
exercise  hereof,  as the  case  may be,  at the  time of the  proposed  sale or
transfer.  Upon exercise, in part or in whole, of this Warrant, each certificate
issued  representing  the Shares  underlying this Warrant shall bear a legend to
the foregoing effect.

            (b) INVESTMENT  REPRESENTATIONS.  The Holder represents that: (i) it
is an accredited investor within the meaning of Regulation D under the Act; (ii)
it is acquiring this Warrant and upon exercise hereof,  the Shares,  for its own
account  for  investment  only,  and not with a view  towards,  or for resale in
connection with, their distribution;  (iii) it has had an opportunity to discuss
the  Company's  business  and  affairs  with  management  of the  Company and is
satisfied with the results thereof;  and (iv) it has also had the opportunity to
ask  questions  of and receive  answers  from,  the  Company and its  management
regarding the terms and conditions of its investment.

            (c)  REGISTRATION  RIGHTS.  The  Holder  shall  have such  rights to
request the Company to register all or any of the Shares  issuable upon exercise
of this Warrant as set forth in the Registration  Rights  Agreement  between the
Company and Holder dated the date hereof.

         4. PRICE.

            (a) INITIAL AND ADJUSTED  PURCHASE PRICE. The initial Purchase Price
shall be equal to the Initial Exercise Price. The adjusted  Purchase Price shall
be the price that shall result from time to time from any and all adjustments of
the  initial  purchase  price in  accordance  with the  provisions  of Section 5
hereof.

            (b) PURCHASE PRICE.  The term "Purchase Price" herein shall mean the
initial Purchase Price or the adjusted Purchase Price, as the case may be.

         5.  ADJUSTMENTS  OF  PURCHASE  PRICE AND NUMBER OF  SHARES.  The Shares
subject to this Warrant and the Purchase  Price thereof  shall be  appropriately
adjusted by the Company in accordance herewith.

            (a)  ADJUSTMENT  TO  PURCHASE  PRICE AND NUMBER OF SHARES.  In case,
prior to the expiration of this Warrant by exercise or by its terms, the Company
shall issue any shares of its Common Stock as a stock  dividend or subdivide the
number  of  outstanding  shares of its  Common  Stock  into a greater  number of
shares,  then in either of such cases,  the then  applicable  purchase price per
share of the shares of Common  Stock  purchasable  pursuant  to this  Warrant in
effect  at the time of such  action  shall be  proportionately  reduced  and the
number of shares at that time  purchasable  pursuant  to this  Warrant  shall be
proportionately  increased;  and  conversely,  in the  event the  Company  shall
contract the number of  outstanding  shares of Common  Stock by  combining  such
shares into a smaller number of shares,  then, in such case, the then applicable
purchase price per share of the shares of Common Stock  purchasable  pursuant to
this  Warrant  in effect  at the time of such  action  shall be  proportionately
increased and the number or shares of Common Stock purchasable  pursuant to this
Warrant shall be  proportionately  decreased.  If the Company shall, at any time
during  the term of this  Warrant,  declare a  dividend  payable  in cash

                                       2
<PAGE>

on its Common  Stock and shall,  at  substantially  the same time,  offer to its
stockholders  a right to  purchase  new Common  Stock from the  proceeds of such
dividend or for an amount substantially equal to the dividend,  all Common Stock
so issued shall, for the purpose of this Warrant,  be deemed to have been issued
as a stock  dividend.  Any dividend  paid or  distributed  upon the Common Stock
shall be treated as a dividend paid in Common Stock to the extent that shares of
Common Stock are issuable upon conversion thereof.

            (b) PURCHASE PRICE RESET  PROVISION.  In the event that prior to the
expiration of this Warrant the Company sells publicly or privately (i) shares of
its Common Stock,  (ii) securities  convertible into shares of its Common Stock,
or  (iii)  options  or  warrants  to  purchase  shares  of its  Common  Stock or
securities  convertible into shares of its Common Stock at a sale, conversion or
exercise price per share (the "Issue Price"),  as the case may be, less than the
Purchase  Price then in effect,  the Purchase  Price shall be reset to the Issue
Price and the number of shares  purchasable  pursuant to this  Warrant  shall be
increased pro rata to the percentage reduction in the Purchase Price,  PROVIDED,
HOWEVER,  that the reset provision shall not apply to (i) any shares issued upon
exercise  or  conversion  of any  currently  outstanding  options,  warrants  or
convertible  securities,  or (ii) any Common Stock options or warrants  issuable
pursuant  to  an  existing   employee   stock  option  plan  or  other  existing
compensation  arrangement or any underlying  Common Stock issued on the exercise
thereof,  but not pursuant to any amendment  relating thereto to the extent such
amendment   increases  the  number  of  shares   issuable  under  such  plan  or
arrangement.  The Issue Price shall be calculated taking into account the amount
paid for the  issuance of such Common  Stock,  option or warrant or  convertible
security  and the  amount,  if any,  payable  upon the  exercise  or  conversion
thereof.

            (c)  RECAPITALIZATION.  In  case,  prior to the  expiration  of this
Warrant by  exercise  or by its terms,  the Company  shall be  recapitalized  by
reclassifying its outstanding Common Stock, (other than a change in par value to
no par value),  or the Company or a successor  corporation  shall consolidate or
merge  with  or  convey  all or  substantially  all  of its or of any  successor
corporation's  property and assets to any other corporation or corporations (any
such other corporations being included within the meaning of the term "successor
corporation"  hereinbefore  used in the event of any  consolidation or merger of
any such other  corporation with, or the sale of all or substantially all of the
property of any such other corporation to, another corporation or corporations),
then,  as  a  condition  of  such  recapitalization,  consolidation,  merger  or
conveyance,  lawful and adequate  provision  shall be made whereby the Holder of
this Warrant shall thereafter have the right to purchase,  upon the basis and on
the terms and  conditions  specified in this  Warrant,  in lieu of the shares of
Common Stock of the Company  theretofore  purchasable  upon the exercise of this
Warrant, such shares of stock,  securities or assets of the other corporation as
to which the Holder of this  Warrant  would have been  entitled had this Warrant
been exercised immediately prior to such recapitalization, consolidation, merger
or  conveyance;  and in any such event,  the rights of the Warrant Holder to any
adjustment in the number of shares of Common Stock purchasable upon the exercise
of this Warrant,  as hereinbefore  provided,  shall continue and be preserved in
respect of any stock which the Holder becomes entitled to purchase.

(d) DISSOLUTION. In case the Company at any time while this Warrant shall remain
unexpired and unexercised shall sell all or substantially all of its property or
dissolve,  liquidate or wind up its affairs,  lawful  provision shall be made as
part of the terms of any such sale,  dissolution,  liquidation or winding up, so
that the Holder of this Warrant may thereafter  receive

                                       3
<PAGE>

upon exercise  hereof in lieu of each share of Common Stock of the Company which
it would  have  been  entitled  to  receive,  the same  kind and  amount  of any
securities or assets as may be issuable , distributable or payable upon any such
sale,  dissolution,  liquidation  or  winding  up with  respect to each share of
Common Stock of the  Company;  PROVIDED,  HOWEVER,  that in any case of any such
sale or of  dissolution,  liquidation  or winding up, the right to exercise this
Warrant shall terminate on a date fixed by the Company. Such date so fixed shall
be no earlier than 3 P.M. New York City Time, on the forty-fifth (45th) day next
succeeding the date on which notice of such termination of the right to exercise
this Warrant has been given by mail to the registered  Holder of this Warrant at
its address as it appears on the books of the Company.

            (e) NO FRACTIONAL  SHARES.  Upon any exercise of this Warrant by the
Holder, the Company shall not be required to deliver fractions of one share, but
adjustment in the purchase  price payable by the Holder shall be made in respect
of any such  fraction of one share on the basis of the purchase  price per share
then applicable upon exercise of this Warrant.

            (f)  NOTICES.  In the event that,  prior to the  expiration  of this
Warrant by  exercise  or by its terms,  the Company  shall  determine  to take a
record of its stockholders for the purpose of determining  stockholders entitled
to receive any dividend, stock dividend,  distribution or other right whether or
not it may cause any change or adjustment in the number, amount, price or nature
of the  securities  or assets  deliverable  upon the  exercise  of this  Warrant
pursuant to the foregoing  provisions,  the Company shall give at least ten (10)
days' prior written  notice to the effect that it intends to take such record to
the registered  Holder of this Warrant at its address as it appears on the books
of the Company, said notice to specify the date as of which such record is to be
taken,  the purpose for which such record is to be taken,  and the effect  which
the action which may be taken will have upon this Warrant.

            (g) REGISTERED  OWNER. The Company may deem and treat the registered
Holder of the Warrant at any time as the absolute owner hereof for all purposes,
and shall not be affected by any notice to the contrary.

            (h) STATUS. This Warrant shall not entitle any Holder thereof to any
of the rights of a stockholder,  and shall not entitle any Holder thereof to any
dividend  declared upon the Common Stock unless the Holder shall have  exercised
the within  Warrant and purchased the shares of Common Stock prior to the record
date fixed by the Board of Directors for the  determination of Holders of Common
Stock entitled to exercise any such rights or receive said dividend.

            (i) NO  ADJUSTMENT  FOR  SMALL  AMOUNTS.  The  Company  shall not be
required to give effect to any adjustment in the Purchase Price unless and until
the net effect of one or more adjustments,  determined as above provided,  shall
have required a change of the Purchase Price by at least ten cents, but when the
cumulative  net effect of more than one  adjustment  so  determined  shall be to
change  the actual  Purchase  Price by at least ten  cents,  such  change in the
Purchase Price shall thereupon be given effect.

         6.  REPLACEMENT  OF  WARRANT.  Upon  receipt by the Company of evidence
reasonably  satisfactory to it of the loss, theft,  destruction or mutilation of
this Warrant,  and, in case of such loss, theft,  destruction or mutilation,  of
indemnity or security reasonably satisfactory to it in its sole discretion,  and
reimbursement to the Company of all expenses incidental or relating thereto,

                                       4
<PAGE>

and upon  surrender and  cancellation  of this Warrant  (unless lost,  stolen or
destroyed),  the Company  will make and deliver a new Warrant of like tenor,  in
lieu of this Warrant.

         7.  NOTICES TO  WARRANT  HOLDER.  Except as set forth in  Section  5(f)
hereto,  nothing contained in this Warrant shall be construed as conferring upon
the Holder  hereof  the right to vote or to  consent  or to receive  notice as a
shareholder  in respect of any  meetings  of  shareholders  for the  election of
directors  or  any  other  matter,  or as  having  any  rights  whatsoever  as a
shareholder of the Company.

         8. NOTICES.  All notices,  requests,  consents and other communications
hereunder  shall be in  writing  and shall be deemed to have been duly made when
delivered, or mailed by registered or certified mail, return receipt requested:

            (a) If to the registered  Holder of this Warrant,  to the address of
such Holder as shown on the books of the Company; or

            (b) If to the Company, to the address set forth on the first page of
this Warrant or to such other  address as the Company may designate by notice to
the Holder.

         9.  SUCCESSORS.  All the  covenants,  agreements,  representations  and
warranties  contained  in this Warrant  shall bind the parties  hereto and their
respective heirs, executors, administrators,  distributees, permitted successors
and permitted  assigns.  This Warrant may not be  transferred  without the prior
written  consent of the Company.  Any  attempted  assignment in violation of the
preceding sentence shall be void and of no effect.

         10. HOLDINGS. The headings in this Warrant are inserted for purposes of
convenience only and shall have no substantive effect.

         11. LAW  GOVERNING.  This Warrant is delivered in the State of New York
and shall be construed  and enforced in  accordance  with,  and governed by, the
laws of the  State of New  York,  without  giving  effect  to  conflicts  of law
principles. Each of the parties agrees to the jurisdiction of the federal courts
whose  districts  encompass any part of the City of New York or the state courts
of the State of New York sitting in the City of New York in connection  with any
dispute  arising  under this Warrant and hereby  waives,  to the maximum  extent
permitted by law, any  objection,  including  any  objection  based on FORUM NON
CONVENIENS, to the bringing of any such proceeding in such jurisdictions.
