               Immtech Pharmaceuticals, Inc., a Delaware corporation ("Company")
hereby grants Ferris, Baker Watts, Incorporated ("Warrant Holder"), on the terms
and  conditions  set forth below,  the right to purchase from the Company at any
time during the Exercise Period  (hereinafter  defined) up to 100,000 fully-paid
and  non-assessable  shares of common stock,  par value $0.01 per share,  of the
Company (the "Common Stock") at the Exercise Price (hereinafter defined).

Section 1.     Definitions.

               "Aggregate Exercise Price" means the Exercise Price multiplied by
the total  number of shares of  Common  Stock for which  this  Warrant  is being
exercised.

               "Exercise Date" means the date this Warrant,  the Exercise Notice
and the Aggregate Exercise Price are received by the Company.

               "Exercise  Notice" means the form  attached  hereto as Exhibit A,
duly executed by the Warrant Holder.

               "Exercise  Period"  means  the  period  beginning  on  the  first
anniversary  of the date of issuance of this  Warrant and  continuing  until the
fifth anniversary thereof;  provided that (i) if the Company exercises its right
to redeem this Warrant  pursuant to Section 4 hereof the  Exercise  Period shall
end on such date of redemption and (ii) the Exercise Period shall terminate upon
any attempted  transfer of this Warrant without the prior written consent of the
Company's Board of Directors.





               "Exercise Price" is $_____(1) per share of Common Stock.

               "Warrant"  means the  right to  purchase  shares of Common  Stock
granted by this warrant.

               "Warrant  Shares"  means  shares of Common  Stock  issuable  upon
exercise of this Warrant.

Section 2. Exercise. (a) This Warrant may be exercised by the Warrant Holder, in
whole or in part,  at any time and from time to time during the Exercise  Period
by the  delivery to the Company at the address set forth in Section 9 hereof (i)
this Warrant,  (ii) the Exercise  Notice duly executed by the Warrant Holder and
(iii) the Aggregate Exercise Price.

               (b)  Payment of the  Aggregate  Exercise  Price  shall be made by
check or bank draft  payable to the order of the Company or by wire  transfer to
an account  designated by the Company;  exercise by exchange of other securities
is not permitted without express written permission of the Company.

               (c) In the event that the Warrant is not  exercised in full,  the
number of Warrant  Shares  shall be reduced by the number of Warrant  Shares for
which the Warrant is exercised, and the Company, at its expense, shall issue and
deliver to the Warrant  Holder a new Warrant in the name of the Warrant  Holder,
reflecting the reduced number of Warrant Shares.

Section  3.  Delivery  of Stock  Certificates.  (a)  Subject  to the  terms  and
conditions of this Warrant,  promptly after the exercise of this Warrant in full
or in part,  the Company will cause to be issued in the name of and delivered to
the Warrant Holder,  or as the Warrant Holder may lawfully direct, a certificate
or certificates for the number of validly issued,  fully paid and non-assessable
Warrant  Shares to which the  Warrant  Holder is  entitled  upon such  exercise,
together with any other stock or other  securities or property  (including cash,
where applicable) to which the Warrant Holder is entitled in accordance with the
provisions hereof.

               (b) This Warrant may not be exercised as to fractional  shares of
Common Stock. In the event that the exercise of this Warrant would result in the
right to  acquire a  fractional  share,  then  such  fractional  share  shall be
considered  a whole  share and shall be added to the  number of  Warrant  Shares
issuable to the Warrant Holder upon exercise of this Warrant.

Section 4.  Redemption.  If, before the expiration of this Warrant,  the closing
price of the Company's  Common Stock on the Company's  principal  trading market
(if the Company Common Stock is not traded on a recognized market then the price
set in good faith by the Company's Board of Directors)  meets or exceeds 200% of
the  Exercise  Price for 20  consecutive  "trading  days"  (days  the  principal
exchange  on which the Common  Stock is traded is open for  business  or, if the
Common Stock is no longer traded on an exchange, business days), the

- --------
(1) 115% of the 10-day Volume Weighted  Average Price, as reported by Bloomberg,
for the 10 days  immediately  preceding  the  effective  date of the  engagement
letter between the Warrant Holder and the Company.




Company may redeem any unexercised  portion of this Warrant for a redemption fee
of $0.01 per share ("Redemption  Fee"). At least 30 days prior to the date fixed
for the  redemption  the Company shall mail written notice to the Warrant Holder
at its address last shown on the records of the Company,  notifying  such holder
of the redemption, specifying the date of the redemption ("Redemption Date") and
the date on which such holder's  exercise  rights  terminate  (which shall be no
more than 5 business  days prior to the  Redemption  Date) and calling upon such
holder to surrender to the Company,  in the manner and at the place  designated,
his Warrant, to the extent unexercised.  From and after the Redemption Date, the
Warrant Holder shall have no rights with respect of the Warrant except the right
to receive the Redemption Fee without interest upon surrender of his Warrant.

Section 5. Rights As Stockholder. Prior to exercise of this Warrant, the Warrant
Holder shall have no rights as a stockholder  of the Company with respect to the
Warrant Shares,  including the right to vote such shares,  receive  dividends or
other distributions, or be notified of stockholder meetings.

Section  6.  Replacement  of  Warrant.   Upon  receipt  of  evidence  reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of the
Warrant and, in the case of any of the foregoing,  upon delivery of an indemnity
agreement or security reasonably  satisfactory in form and amount to the Company
or, in the case of any such  mutilation,  on surrender and  cancellation of such
Warrant, the Company at its expense will execute and deliver, in lieu thereof, a
new Warrant of like tenor.

Section 7. Restricted Securities.  The securities evidenced by this Warrant have
not been  registered  under the U.S.  Securities  Act of 1933, as amended,  (the
"Securities  Act") or any other laws and have been  issued in  reliance  upon an
exemption  from the  registration  requirements  of the  Securities Act and such
other  laws.  Neither  the  securities  evidenced  by this  certificate  nor any
interest or participation herein may be offered,  sold,  assigned,  transferred,
pledged, encumbered, hypothecated or otherwise disposed of except pursuant to an
effective  registration  statement  under the Securities Act or in a transaction
exempt from, or not subject to, the registration  requirements of the Securities
Act. Any replacement  Warrants issued pursuant to Sections 2 or 6 hereof and any
Warrant Shares issued upon exercise  hereof,  shall bear the legend set forth at
the head of this  Warrant.  Such legend  shall only be removed in the event that
the security which would  otherwise  bear such legend is registered  pursuant to
the  Securities  Act or the party  seeking to remove  such legend  provides  the
Company with an opinion of counsel,  which opinion shall be  satisfactory to the
Company, stating the removal of such legend is appropriate.

Section 8.  Transferability  and Exchange.  This  Warrant,  and the Common Stock
issuable  upon the exercise  hereof,  may not be sold,  transferred,  pledged or
hypothecated  unless the  Company  shall have been  provided  with an opinion of
counsel  reasonably  satisfactory to the Company,  or other evidence  reasonably
satisfactory  to it, that such  transfer is not in violation  of the  Securities
Act, or any applicable state securities laws. Subject to the satisfaction of the
aforesaid condition,  this Warrant and the underlying shares of Common Stock may
be transferred  to an employee or affiliate of the original  Warrant Holder upon
written notice to the Company.  If this Warrant is  transferred,  in whole or in
part, the Company shall, upon surrender of this Warrant to the Company,  deliver
to such  transferee  a  Warrant  of like  tenor  evidencing  the  right





of such  transferee  to purchase  the number of shares of Common Stock that such
transferee is entitled to purchase  pursuant to such  transfer.  A transferee of
the original  registered Warrant Holder becomes a registered Warrant Holder only
upon delivery to the Company of the original Warrant and an original assignment,
substantially in the form set forth in Exhibit B attached hereto.
