          surrender, or if such day shall not be a business day, at the close of
          business on the next succeeding business day.

                                      -90-
<PAGE>

     2.   Notwithstanding the other provisions of this Section 5, Maker reserves
          the right to delay  giving  effect to any  conversion  until the Payee
          shall deliver to Maker the letter  hereinabove  referred to as Exhibit
          "A".  In this  connection,  Maker also  reserves  the right to imprint
          restrictive  legends on the  Certificates  representing  any shares of
          Common Stock (or other equity  securities)  into which this Note shall
          be  converted  and to place stop  transfer  orders  against  the same.
          Nothing  contained herein shall be construed as requiring  counsel for
          Maker to  subsequently  issue any opinion letter that  registration is
          not  required,  and such  counsel  may refuse to issue such an opinion
          letter on any reasonable  grounds or may require  opinion letters from
          counsel for the  proposed  transferor,  affidavits  from the  proposed
          transferor or  transferee,  letters from the  Securities  and Exchange
          Commission  or any other  documents  which said counsel may deem to be
          necessary or desirable and proper as a condition  precedent to issuing
          such an opinion letter.

     3.   No fractional shares or script  representing  fractional shams will be
          issued upon the  conversion  of this Note.  In lieu of the issuance of
          any fractional share otherwise called for upon such conversion,  Maker
          will pay to the applicable holder an amount in cash equal to the value
          of such fractional share, based upon the applicable conversion price.

     4.   The  holder of the Common  Stock  into  which this Note was  converted
          shall have the same rights to have such Common Stock  registered  on a
          Registration  Statement  on Form SB-2 as the holder of Common Stock in
          the Company issued  pursuant to a letter  agreement dated May 24, 2000
          with  First  Fidelity  Capital,  Inc.,  on all of the same  terms  and
          conditions set forth in the definitive documents with First Fidelity.

6.   Governing Law.
     --------------
     This Note shall be governed by and construed in accordance with the laws of
     the State of  Florida  applicable  to  contracts  made and to be  performed
     wholly  within   Florida,   without  giving  effect  to  conflict  of  laws
     principles.

7.   Notices.
     --------
     Any notice or other  communication  required or  permitted  under this Note
     shall be in  writing  and shall be deemed to have been duly  given (i) upon

                    COMMON STOCK PURCHASE WARRANT CERTIFICATE

                   THE WARRANTS EVIDENCED BY THIS CERTIFICATE
                                       ARE NOT EXERCISABLE AFTER 5:00 P.M.,
                             NEW YORK CITY TIME, ON
                                ___________, 2005

THIS CERTIFIES THAT ________________________ or registered assigns is the
registered holder (the "Registered Holder") of the number of Warrants set forth
above, each of which represents the right to purchase one fully paid and
non-assessable share of Common Stock, par value $0.01 per share (the "Common
Stock"), of Palatin Technologies, Inc., a Delaware corporation (the "Company"),
at the initial exercise price of $0.01 per Warrant (the "Exercise Price") at any
time prior to the Expiration Date (as hereinafter defined), by surrendering this
Warrant Certificate, with the Form of Election to Purchase duly executed at the
principal office of the Company and by paying in full the Exercise Price, plus
transfer taxes, if any. Payment of the Exercise Price shall be made in United
States currency, by certified check or money order payable to the order of the
Company. The Warrants have been issued pursuant to a private placement of
Warrants. With respect to the Common Stock issuable on exercise of Warrants, the
Registered Holder has the registration rights set forth in the Appendix to this
Warrant certificate. By exercising a Warrant, the Registered Holder agrees to be
bound by the terms of the registration rights set forth in the Appendix.

                              EXERCISE OF WARRANTS

         Issuance of Common Stock. As soon as practicable after the date of
exercise of any Warrants, the Company shall issue, or cause the transfer agent
for the Common Stock, if any, to issue a certificate or certificates for the
number of full shares of Common Stock to which such Registered Holder is
entitled, registered in accordance with the instructions set forth in the Form
of Election to Purchase. All shares of Common Stock issued upon the exercise of
any Warrants shall be validly authorized and issued, fully paid and
non-assessable, and free from all taxes, liens and charges created by the
Company in respect of the issue thereof. Each person in whose name any such
certificate for shares of Common Stock is issued shall for all purposes be
deemed to have become the holder of record of the Common Stock represented
thereby on the date of exercise of the Warrants resulting in the issuance of
such shares, irrespective of the date of issuance or delivery of such
certificate for shares of Common Stock.

         Certificates for Unexercised Warrants. In the event that less than all
of the Warrants represented by a Warrant Certificate are exercised, the Company
shall execute and mail, by first-class mail, within 30 days of the date of
exercise, to the Registered Holder of such Warrant Certificate, or such other
person as shall be designated in the Form of Election to Purchase, a new Warrant
Certificate representing the number of full Warrants not exercised. In no event
shall a fraction of a Warrant be exercised, and the Company shall distribute no
Warrant Certificates representing fractions of Warrants. Final fractions of
shares shall be treated as provided for herein.

         Reservation of Shares. The Company shall at all times reserve and keep
available for issuance upon the exercise of Warrants a number of its authorized
but unissued shares of Common Stock that will be sufficient to permit the
exercise in full of all outstanding Warrants.

                        ADJUSTMENTS AND NOTICE PROVISIONS

         Adjustment of Exercise Price. Subject to the provisions hereof, the
Exercise Price in effect from time to time shall be subject to adjustment, as
follows:

<PAGE>

         (a) In case the Company shall at any time after the date hereof (i)
declare a dividend on the outstanding Common Stock payable in shares of its
capital stock, (ii) subdivide the outstanding Common Stock, (iii) combine the
outstanding Common Stock into a smaller number of shares, or (iv) issue any
shares of its capital stock by reclassification of the Common Stock (including
any such reclassification in connection with a consolidation or merger in which
the Company is the continuing corporation), then, in each case, the Exercise
Price, and the number of shares of Common Stock issuable upon exercise of the
Warrants in effect at the time of the record date for such dividend or of the
effective date of such subdivision, combination, or reclassification, shall be
proportionately adjusted so that the Holders of the Warrants after such time
shall be entitled to receive the aggregate number and kind of shares which, if
such Warrants had been exercised immediately prior to such time, such Registered
Holders would have owned upon such exercise and been entitled to receive by
virtue of such dividend, subdivision, combination or reclassification. Such
adjustment shall be made successively whenever any event listed above shall
occur.

<PAGE>

         (b) In case the Company shall issue or fix a record date for the
issuance to all holders of Common Stock of rights, options, or warrants to
subscribe for or purchase Common Stock (or securities convertible into or
exchangeable for Common Stock) at a price per share (or having a conversion or
exchange price per share, if a security convertible into or exchangeable for
Common Stock) less than the Current Market Price per share of Common Stock (as
determined below) on such record date, then, in each case, the Exercise Price
shall be adjusted by multiplying the Exercise Price in effect immediately prior
to such record date by a fraction, the numerator of which shall be the number of
shares of Common Stock outstanding on such record date plus the number of shares
of Common Stock which the aggregate offering price of the total number of shares
of Common Stock so to be offered (or the aggregate initial conversion or
exchange price of the convertible or exchangeable securities so to be offered)
would purchase at such Current Market Price and the denominator of which shall
be the number of shares of Common Stock outstanding on such record date plus the
number of additional shares of Common Stock to be offered for subscription or
purchase (or into which the convertible or exchangeable securities so to be
offered are initially convertible or exchangeable). Such adjustment shall become
effective at the close of business on such record date; provided, however, that,
to the extent the shares of Common Stock (or securities convertible into or
exchangeable for shares of Common Stock) are not delivered, the Exercise Price
shall be readjusted after the expiration of such rights, options, or warrants
(but only with respect to Warrants exercised after such expiration), to the
Exercise Price which would then be in effect had the adjustments made upon the
issuance of such rights, options, or warrants been made upon the basis of
delivery of only the number of shares of Common Stock (or securities convertible
into or exchangeable for shares of Common Stock) actually issued.
Notwithstanding anything to the contrary contained herein, no adjustment shall
be made to the Exercise Price until any condition to the vesting of such rights,
options or warrants shall be fulfilled or satisfied (and then only with respect
to the portion thereof which shall have vested). In case any subscription price
may be paid in a consideration part or all of which shall be in a form other
than cash, the value of such consideration shall be as determined in good faith
by the board of directors of the Company, whose determination shall be
conclusive absent manifest error. Shares of Common Stock owned by or held for
the account of the Company or any majority-owned subsidiary shall not be deemed
outstanding for the purpose of any such computation.

         (c) In case the Company shall distribute to all holders of Common Stock
(including any such distribution made to the stockholders of the Company in
connection with a consolidation or merger in which the Company is the continuing
corporation) evidences of its indebtedness, cash (other than any cash dividend
which, together with any cash dividends paid within the twelve (12) months prior
to the record date for such distribution, does not exceed 5% of the Current
Market Price at the record date for such distribution) or assets (other than
distributions and dividends payable in shares of Common Stock), or rights,
options, or warrants to subscribe for or purchase Common Stock, or securities
convertible into or exchangeable for shares of Common Stock (excluding those
with respect to the issuance of which an adjustment of the Exercise Price is
provided pursuant to the foregoing paragraph), then, in each case, the Exercise
Price shall be adjusted by multiplying the Exercise Price in effect immediately
prior to the record date for the determination of stockholders entitled to
receive such distribution by a fraction, the numerator of which shall be the
Current Market Price per share of Common Stock on such record date, less the
fair market value (as determined in good faith by the board of directors of the
Company, whose determination shall be conclusive absent manifest error) of the
portion of the evidences of indebtedness or assets so to be distributed, or of
such rights, options, or warrants or convertible or exchangeable securities, or
the amount of such cash, applicable to one share, and the denominator of which
shall be such Current Market Price per share of Common Stock. Such adjustment
shall become effective at the close of business on such record date.

<PAGE>

         Current Market Price. For the purpose of any computation under this
Warrant, the Current Market Price per share of Common Stock on any date shall be
deemed to be the average of the daily closing prices for the fifteen (15)
consecutive trading days immediately preceding the date in question. The closing
price for each day shall be (a) the last reported sales price regular way or, in
case no such reported sale takes place on such day, the closing bid price
regular way, in either case on the principal national securities exchange or
market system (including, for purposes hereof, the American Stock Exchange
("AMEX")) on which the Common Stock, is listed or admitted to trading, (b) if
the Common Stock, is not listed or admitted to trading on any national
securities exchange or market system, the highest reported bid price for the
Common Stock, as furnished by the National Association of Securities Dealers,
Inc. through AMEX or a similar organization if AMEX is no longer reporting such
information, or (c) if on any such date the Common Stock is not listed or
admitted to trading on any national securities exchange and is not quoted by
AMEX or any similar organization, as determined by reference to the "pink
sheets" published by the National Quotation Bureau or, if not so published, by
such other method of determining the market value of a share of Common Stock, as
the board of directors of the Company shall in good faith from time to time deem
to be fair, whose determination shall be conclusive absent manifest error.

         No Adjustments to Exercise Price. No adjustment in the Exercise Price
shall be required if such adjustment is less than $.05; provided, however, that
any adjustments which by reason of this Warrant are not required to be made
shall be carried forward and taken into account in any subsequent adjustment.
All calculations under this Warrant shall be made to the nearest cent or to the
nearest one thousandth of a share, as the case may be.

         Deferral of Adjustments to Exercise Price. In any case in which this
Warrant shall require that an adjustment in the Exercise Price be made effective
as of a record date for a specified event, the Company may elect to defer, until
the occurrence of such event, issuing to the Registered Holders of the Warrants,
if any Registered Holder has exercised a Warrant after such record date, the
shares of Common Stock, if any, issuable upon such exercise over and above the
shares of Common Stock, if any, issuable upon such exercise on the basis of the
Exercise Price in effect prior to such adjustment; provided, however, that the
Company shall deliver to such exercising Registered Holder a due bill or other
appropriate instrument evidencing such Registered Holder's right to receive such
additional shares upon the occurrence of the event requiring such adjustment.

         Adjustment to Number of Shares. Upon each adjustment of the Exercise
Price as a result of the calculations made above the Warrants shall thereafter
evidence the right to purchase, at the adjusted Exercise Price, that number of
shares (calculated to the nearest thousandth) obtained by dividing (A) the
product obtained by multiplying the number of shares purchasable upon exercise
of the Warrants prior to adjustment of the number of shares by the Exercise
Price in effect prior to adjustment of the Exercise Price by (B) the Exercise
Price in effect after such adjustment of the Exercise Price.

<PAGE>

         Reorganization. In case of any capital reorganization, other than in
the cases referred to above, or the consolidation or merger of the Company with
or into another corporation (other than a merger or consolidation in which the
Company is the continuing corporation and which does not result in any
reclassification of the outstanding shares of Common Stock or the conversion of
such outstanding shares of Common Stock into shares of other stock or other
securities or property), or the sale of the property of the Company as an
entirety or substantially as an entirety (collectively such actions being
hereinafter referred to as "Reorganizations"), there shall thereafter be
deliverable upon exercise of any Warrant (in lieu of the number of shares of
Common Stock theretofore deliverable) the number of shares of stock or other
securities or property to which a Registered Holder of the number of shares of
Common Stock which would otherwise have been deliverable upon the exercise of
such Warrant would have been entitled upon such Reorganization if such Warrant
had been exercised in full immediately prior to such Reorganization. In case of
any Reorganization, appropriate adjustment, as determined in good faith by the
Board of Directors of the Company, shall be made in the application of the
provisions herein set forth with respect to the rights and interests of
Registered Holders so that the provisions set forth herein shall thereafter be
applicable, as nearly as practicable, in relation to any shares or other
property thereafter deliverable upon exercise of Warrants. The Company shall not
effect any such Reorganization, unless upon or prior to the consummation thereof
the successor corporation, or if the Company shall be the surviving corporation
in any such Reorganization and is not the issuer of the shares of stock or other
securities or property to be delivered to holders of shares of the Common Stock
outstanding at the effective time thereof, then such issuer, shall assume by
written instrument the obligation to deliver to the Registered Holder of any
Warrant Certificate such shares of stock, securities, cash or other property as
such holder shall be entitled to purchase in accordance with the foregoing
provisions. Notwithstanding anything to the contrary contained herein, in the
event of sale or conveyance or other transfer of all or substantially all of the
assets of the Company as a part of a plan for liquidation of the Company, all
rights to exercise any Warrant shall terminate thirty (30) days after the
Company gives written notice to each Registered Holder of a Warrant Certificate
that such sale or conveyance of other transfer has been consummated.

         Reclassifications. (a) In case of any reclassification or change of the
shares of Common Stock issuable upon exercise of the Warrants (other than a
change in par value or from no par value to a specified par value, or as a
result of a subdivision or combination, but including any change in the shares
into two or more classes or series of shares), the Registered Holders of the
Warrants shall have the right thereafter to receive upon exercise of the
Warrants solely the kind and amount of shares of stock and other securities,
property, cash, or any combination thereof receivable upon such reclassification
or change by a Registered Holder of the number of shares of Common Stock for
which the Warrants might have been exercised immediately prior to such
reclassification or change. Thereafter, appropriate provision shall be as nearly
equivalent as practicable to the adjustments in this Warrant. The above
provisions of this paragraph shall similarly apply to successive
reclassifications and changes of shares of Common Stock.

<PAGE>

         (b) Notwithstanding anything to the contrary herein contained, in the
event of a transaction contemplated by the prior paragraph in which the
surviving, continuing, successor, or purchasing corporation demands that all
outstanding Warrants be extinguished prior to the closing date of the
contemplated transaction, the Company shall give prior notice (the "Merger
Notice") thereof to the Registered Holders advising them of such transaction.
The Registered Holders shall have ten (10) days after the date of the Merger
Notice to elect to (i) exercise the Warrants in the manner provided herein or
(ii) receive from the surviving, continuing, successor, or purchasing
corporation, with respect to outstanding Warrants, the same consideration
receivable by a Registered Holder of the number of shares of Common Stock for
which the Warrants might have been exercised immediately prior to such
consolidation, merger, sale, or purchase reduced by such amount of the
consideration as has a market value equal to the exercise price of the Warrants,
as determined by the Board of Directors of the Company, whose determination
shall be conclusive absent manifest error. If any Registered Holder fails to
timely notify the Company of its election, the Holder shall be deemed for all
purposes to have elected the option set forth in (ii) above. Any amounts
receivable by a Holder who has elected the option set forth in (ii) above shall
be payable at the same time as amounts payable to stockholders in connection
with any such transaction.

         Verification of Computations. Whenever the Exercise Price is adjusted
as provided in this Warrant, the Company will promptly obtain a certificate of
the chief financial officer of the Company setting forth the Exercise Price as
so adjusted and a brief statement of the facts accounting for such adjustment,
and will make available a brief summary thereof to the Registered Holders of the
Warrant Certificates, at their addresses listed on the register maintained for
the purpose by the Company.

         Exercise Price Not Less Than Par Value. In no event shall the Exercise
Price be adjusted below the par value per share of the Common Stock.

          Notice of Certain Actions. In case at any time the Company shall
          propose:

                  (a) to pay any dividend or make any distribution on shares of
         Common Stock in shares of Common Stock or make any other distribution
         (other than regularly scheduled cash dividends which are not in a
         greater amount per share than the most recent such cash dividend) to
         all holders of Common Stock; or

                  (b) to issue any rights, warrants, or other securities to all
         holders of Common Stock entitling them to purchase any additional
         shares of Common Stock or any other rights, warrants, or other
         securities; or

               (c) to effect any reclassification or change of outstanding
          shares of Common Stock, or any consolidation, merger, sale, lease, or
          conveyance of property, described above; or

               (d) to effect any liquidation, dissolution, or winding-up of the
          Company;

then, in each such case, the Company shall cause notice of such proposed action
to be mailed to each Registered Holder of a Warrant Certificate. Such notice
shall be mailed, at least ten (10) days prior to the record date for determining
holders of the Common Stock for purposes of receiving such payment or offer or
at least ten (10) days prior to the earlier of the date upon which such action
is to take place or any record date to determine holders of Common Stock
entitled to receive such securities or other property, as the case may be.

<PAGE>

         Notice of Adjustments. Whenever any adjustment is made pursuant to this
Warrant, the Company shall cause notice of such adjustment to be mailed to each
Registered Holder of a Warrant Certificate within fifteen (15) days thereafter,
such notice to include in reasonable detail (i) the events precipitating the
adjustment, (ii) the computation of any adjustments, and (iii) the Exercise
Price, the number of shares or the securities or other property purchasable upon
exercise of each Warrant after giving effect to such adjustment.

         Warrant Certificate Amendments. Irrespective of any adjustments
pursuant to this Warrant, Warrant Certificates theretofore or thereafter issued
need not be amended or replaced, but certificates thereafter issued shall bear
an appropriate legend or other notice of any adjustments.

         Fractional Shares. The Company shall not be required upon the exercise
of any Warrant to issue fractional shares of Common Stock which may result from
adjustments in accordance with this Warrant to the Exercise Price or number of
shares of Common Stock purchasable under each Warrant. If more than one Warrant
is exercised at one time by the same Registered Holder, the number of full
shares of Common Stock which shall be deliverable shall be computed based on the
number of shares deliverable in exchange for the aggregate number of Warrants
exercised. With respect to any final fraction of a share called for upon the
exercise of any Warrant or Warrants, the Company shall pay a cash adjustment in
respect of such final fraction in an amount equal to the same fraction of the
Current Market Price of a share of Common Stock calculated in accordance with
this Warrant.

         Adjustments Not Provided For. If any change to the capitalization of
the Company should occur with respect to which a favorable adjustment to the
rights and interests of the Registered Holders of the Warrants should be made,
and such adjustment is not otherwise provided for in this Warrant, such
appropriate adjustment should be made as determined in good faith by the Board
of Directors of the Company.

         No Warrant may be exercised after 5:00 P.M., New York City time, on the
expiration date (the "Expiration Date") which will be March 15, 2005. All
Warrants evidenced hereby shall thereafter become void.

                          OTHER PROVISIONS RELATING TO
                          RIGHTS OF REGISTERED HOLDERS
                            OF WARRANT CERTIFICATES

         Rights of Warrant Holders. No Warrant Certificate shall entitle the
registered holder thereof to any of the rights of a stockholder of the Company,
including, without limitation, the right to vote, to receive dividends and other
distributions, to receive any notice of, or to attend, meetings of stockholders
or any other proceedings of the Company.

<PAGE>

         Lost, Stolen, Mutilated or Destroyed Warrant Certificates. If any
Warrant Certificate shall be mutilated, lost, stolen or destroyed, the Company
in its discretion may execute and deliver, in exchange and substitution for and
upon cancellation of a mutilated Warrant Certificate, or in lieu of or in
substitution for a lost, stolen or destroyed Warrant Certificate, a new Warrant
Certificate for the number of Warrants represented by the Warrant Certificate so
mutilated, lost, stolen or destroyed but only upon receipt of evidence of such
loss, theft or destruction of such Warrant Certificate, and of the ownership
thereof, and indemnity, if requested, all satisfactory to the Company.
Applicants for such substitute Warrant Certificates shall also comply with such
other reasonable regulations and pay such other reasonable charges incidental
thereto as the Company may prescribe. Any such new Warrant Certificate shall
constitute an original contractual obligation of the Company, whether or not the
allegedly lost, stolen, mutilated or destroyed Warrant Certificate shall be at
any time enforceable by anyone.

                                 SPLIT UP, COMBINATION, EXCHANGE, TRANSFER,
                    AND CANCELLATION OF WARRANT CERTIFICATES

         Split Up, Combination, Exchange and Transfer of Warrant Certificates.
Prior to the latest time at which the Warrants may be exercised, subject to any
applicable laws, rules or regulations restricting transferability, Warrant
Certificates, subject to the provisions hereof, may be split up, combined or
exchanged for other Warrant Certificates representing a like aggregate number of
Warrants or may be transferred in whole or in part. Any holder desiring to split
up, combine or exchange a Warrant Certificate or Warrant Certificates shall make
such request in writing delivered to the Company at its principal office and
shall surrender the Warrant Certificate or Warrant Certificates so to be split
up, combined or exchanged at said office with the Form of Assignment. Upon any
such surrender for split up, combination, exchange or transfer, the Company
shall execute and deliver to the person entitled thereto a Warrant Certificate
or Warrant Certificates, as the case may be, as so requested in the Form of
Assignment. The Company may require the holder to pay a sum sufficient to cover
any tax or governmental charge that may be imposed in connection with any split
up, combination, exchange or transfer of Warrant Certificates prior to the
issuance of any new Warrant Certificate.

         Cancellation of Warrant Certificates. Any Warrant Certificate
surrendered upon the exercise of Warrants or for split up, combination, exchange
or transfer, or purchased or otherwise acquired by the Company, shall be
canceled and shall not be reissued by the Company; and, except as otherwise
provided herein in case of the exercise of less than all of the Warrants
evidenced by a Warrant Certificate or in case of a split up, combination,
exchange or transfer, no Warrant Certificate shall be issued hereunder in lieu
of such canceled Warrant Certificate. Any Warrant Certificate so canceled shall
be destroyed by the Company.

         Agreement of Warrant Certificate Holders. Every holder of a Warrant
Certificate by accepting the same consents and agrees with the Company and with
every other holder of a Warrant Certificate that:

<PAGE>

                  (a) transfer of the Warrant Certificates shall be registered
         on the books of the Company only if surrendered at the principal office
         of the Company, duly endorsed or accompanied by a proper instrument of
         transfer; and

                  (b) prior to due presentment for registration of transfer, the
         Company may deem and treat the person in whose name the Warrant
         Certificate is registered as the absolute owner thereof and of the
         Warrants evidenced thereby (notwithstanding any notations of ownership
         or writing on the Warrant Certificates made by anyone other than the
         Company) for all purposes whatsoever, and the Company shall not be
         affected by any notice to the contrary.

                                  OTHER MATTERS

               Governing Law. The laws of the State of New York shall govern
          this Warrant Certificate.

         IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to
be duly executed.

                         offering of its Common Stock, other than (i) pursuant

                         give written notice of such proposed Registration to

                    (c)  The Company shall have the exclusive right to select
                         all underwriters for any underwritten public offering
                         of securities of the Company, including all Warrant
                         Shares. In the event that the proposed Registration by
                         the Company is, in whole or in part, an underwritten
                         public offering of securities of the Company, any
                         request under Section 2.2(b) shall contain the holder's
                         agreement that the Registrable Securities will be
                         included in the underwriting on the same terms and
                         conditions as the shares of Common Stock, if any,
                         otherwise being sold through underwriters under such
                         Registration.

                    (d)  Upon receipt of a written request pursuant to Section
                         2.2(b), the Company shall promptly use its best efforts
                         to cause all such Registrable Securities to be
                         Registered, to the extent required to permit sale or
                         disposition as set forth in the written request.

                    (e)  Notwithstanding the foregoing, if the managing
                         underwriter of an underwritten public offering
                         determines and advises in writing that the inclusion of
                         all Registrable Securities proposed to be included in
                         the underwritten public offering, together with any
                         shares proposed to be sold by the Company for its own
                         account and any other issued and outstanding shares of
                         Common Stock proposed to be included therein by holders
                         other than the holders of Registrable Securities (such
                         other holders' shares hereinafter collectively referred
                         to as the "Other Shares"), would interfere with the
                         successful marketing of the securities proposed to be
                         included in the underwritten public offering, including
                         the price at which such securities can be sold, then
                         the number of such shares of persons other than the
                         Company that otherwise would be included in such
                         underwritten public offering shall be excluded from
                         such underwritten public offering in a number deemed
                         necessary by such managing underwriter, first by
                         excluding, to the extent necessary, other shares held
                         by persons who have not exercised contractual rights to
                         include such Shares in the offering pursuant to the
                         Prior Registration Rights Agreements (as hereinafter
                         defined), and then, to the extent necessary, by
                         excluding Registrable Securities participating in such
                         underwritten public offering, pro rata, based on the
                         number of shares of Registrable Securities each holder
                         proposes to include; and, then, excluding to the extent
                         necessary, other Shares proposed to be included by the
                         holders of other Shares who have exercised registration
                         rights granted to them under registration rights
                         agreements of the Company in effect on the date hereof
                         or any other registration rights in effect on the date
                         hereof (collectively, the "Prior Registration Rights
                         Agreements").

                    (f)  All Warrant Shares that are not included in an
                         underwritten public offering pursuant to Section 2.2
                         shall be withheld from the market by the holders
                         thereof for a period, not to exceed 12 months following
                         a public offering, that the managing underwriter
                         reasonably determines is necessary in order to effect
                         the underwritten public offering. The holders of such
                         Warrant Shares shall execute such documentation as the
                         managing underwriter reasonably requests to evidence
                         this lock-up.

                    (g)  The registration rights provided by this Appendix shall
                         expire with respect to any Registrable Security upon
                         the earliest to occur of (i) the effectiveness of a
                         Registration Statement that includes in the
                         Registration effected thereby, at the request of a
                         Selling Stockholder, such Registrable Security; (ii)
                         the date on which such Registrable Security is eligible
                         for resale under Rule 144 without regard to the volume
                         limitations thereof; and (iii) five years from the date
                         hereof.

         2.3      Preparation and Filing. If and whenever the Company is under
                  an obligation pursuant to the provisions of this Section 2 to
                  use its best efforts to effect the Registration of any
                  Registrable Securities, the Company shall, as expeditiously as
                  practicable:

                  (a)      prepare and file with the Commission a Registration
                           Statement with respect to such Registrable
                           Securities, using such form of available Registration
                           Statement as is reasonably selected by the Company
                           (unless otherwise specified herein), and use its best
                           efforts to cause such Registration Statement to
                           become and remain effective, keeping each Selling
                           Stockholder advised as to the initiation, progress
                           and completion of the Registration;

                  (b)      prepare and file with the Commission such amendments
                           and supplements to such Registration Statements and
                           the prospectus used in connection therewith as may be
                           necessary to keep such Registration Statement
                           effective for six months, and to comply with the
                           provisions of the Securities Act with respect to the
                           sale or other disposition of all Registrable
                           Securities covered by such Registration Statement;

                  (c)      furnish to each Selling Stockholder such number of
                           copies of any summary prospectus or other prospectus,
                           including a preliminary prospectus and all amendments
                           and supplements thereto, in conformity with the
                           requirements of the Securities Act, and such other
                           documents as such Selling Stockholder may reasonably
                           request in order to facilitate the public sale or
                           other disposition of such Registrable Securities;
                           provided, however, that no such prospectus need be
                           furnished more than six months after the effective
                           date of the Registration Statement related thereto;

                    (d)  use its best efforts to register or qualify the
                         Registrable Securities covered by such Registration
                         Statement under the securities or blue sky laws of such
                         jurisdictions as each Selling Stockholder shall
                         reasonably request and do any and all other acts or
                         things which may be reasonably necessary or advisable
                         to enable such holder to consummate the public sale or
                         other disposition in such jurisdictions of such
                         Registrable Securities; provided, however, that the
                         Company shall not be required to consent to general
                         service of process, qualify to do business as a foreign
                         corporation where it would not be otherwise required to
                         qualify or submit to liability for state or local taxes
                         where it is not liable for such taxes or provide any
                         undertaking or make any change in its Certificate of
                         Incorporation; and

                    (e)  at any time when a prospectus covered by such
                         Registration Statement is required to be delivered
                         under the Securities Act within the appropriate period
                         mentioned in Section 2.3(b) hereof, notify each Selling
                         Stockholder of the happening of any event as a result
                         of which the prospectus included in such Registration
                         Statement, as then in effect, includes an untrue
                         statement of a material fact or omits to state a
                         material fact required to be stated therein or
                         necessary to make the statements therein not misleading
                         in the light of the circumstances then existing and, at
                         the request of such seller, prepare, file and furnish
                         to such seller a reasonable number of copies of a
                         supplement to or an amendment of such prospectus as may
                         be necessary so that, as thereafter delivered to the
                         purchasers of such shares, such prospectus shall not
                         include an untrue statement of a material fact or omit
                         to state a material fact required to be stated therein
                         or necessary to make the statement therein not
                         misleading in the light of the circumstances then
                         existing. The Company may delay amending or
                         supplementing the prospectus for a period of up to 90
                         days if the Company is then engaged in negotiations
                         regarding a material transaction that has not been
                         publicly disclosed, and the Selling Stockholders shall
                         suspend their sale of Shares until an appropriate
                         supplement or prospectus has been forwarded to them or
                         the proposed transaction is abandoned.

         Notwithstanding the foregoing, with respect to the proposed
         Registration of Registrable Securities pursuant to Section 2.2 hereof,
         the Company may withdraw or cease proceeding with any proposed
         Registration of Registrable Securities if it has withdrawn or ceased
         proceeding with the proposed Registration of Common Stock of the
         Company with which the Registration of such Registrable Securities was
         to be included.

          2.4  Expenses. The Company shall pay all Registration Expenses
               incurred by the Company in complying with this Section 2.

         2.5      Information Furnished by Registered Holder. It shall be a
                  condition precedent to the Company's obligations under this
                  Appendix as to any Selling Stockholder that each Selling
                  Stockholder furnish to the Company in writing such information
                  regarding such Selling Stockholder and the distribution
                  proposed by such Selling Stockholder as the Company may
                  reasonably request.

         2.6      Indemnification.

               2.6.1 Company's Indemnification of Registered Holders. The
                    Company shall indemnify each Selling Stockholder, each of
                    its officers, directors and constituent partners, and each
                    person controlling (within the meaning of the Securities
                    Act) such Selling Stockholder, against all claims, losses,
                    damages or liabilities (or actions in respect thereof)
                    suffered or incurred by any of them, to the extent such
                    claims, losses, damages or liabilities arise out of or are
                    based upon any untrue statement (or alleged untrue
                    statement) of a material fact contained in any prospectus or
                    any related Registration Statement incident to any such
                    Registration, or any omission (or alleged omission) to state
                    therein a material fact required to be stated therein or
                    necessary to make the statements therein not misleading, or
                    any violation by the Company of any rule or regulation
                    promulgated under the Securities Act applicable to the
                    Company and relating to actions or inaction required of the
                    Company in connection with any such Registration; and the
                    Company will reimburse each such Selling Stockholder, each
                    of its officers, directors and constituent partners and each
                    person who controls any such Selling Stockholder, for any
                    reasonable, documented legal and other expenses incurred in
                    connection with investigating or defending any such claim,
                    loss, damage, liability or action; provided, however, that
                    the indemnity contained in this Section 2.6.1 shall
                    not apply to amounts paid in settlement of any such
                    claim, loss, damage, liability or action if settlement is
                    effected without the consent of the Company (which consent
                    shall not unreasonably be withheld); and provided, further,
                    that the Company will not  be liable in any
                    such case to the extent that any such claim, loss, damage,
                    liability or expense arises out of or is based upon any
                    untrue (or alleged untrue) statement or omission based upon
                    written information furnished to the Company by such Selling
                    Stockholder, underwriter, controlling person or other
                    indemnified person and stated to be for use in connection
                    with the offering of securities of the Company.

               2.6.2 Selling Stockholder's Indemnification of Company. Each
                    Selling Stockholder shall indemnify the Company, each of its
                    directors and officers, each underwriter, if any, of the
                    Company's securities covered by a Registration Statement,
                    each person who controls the Company or such underwriter
                    within the meaning of the Securities Act, and each other
                    Selling Stockholder, each of its officers, directors and
                    constituent partners and each person controlling such other
                    Selling Stockholder, against all claims, losses, damages and
                    liabilities (or actions in respect thereof) suffered or
                    incurred by any of them and arising out of or based upon any
                    untrue statement (or alleged untrue statement) of a material
                    fact contained in such Registration Statement or related
                    prospectus, or any omission (or alleged omission) to state
                    therein a material fact required to be stated therein or
                    necessary to make the statements therein not misleading, or
                    any violation by such Selling Stockholder of any rule or
                    regulation promulgated under the Securities Act applicable
                    to such Selling Stockholder and relating to actions or
                    inaction required of such Selling Stockholder in connection
                    with the Registration of the Registrable Securities pursuant
                    to such Registration Statement; and will reimburse the
                    Company, such other Selling Stockholders, such directors,
                    officers, partners, persons, underwriters and controlling
                    persons for any reasonable, documented legal and other
                    expenses incurred in connection with investigating or
                    defending any such claim, loss, damage, liability or action;
                    provided, however, that such indemnification and
                    reimbursement shall be to the extent, ------- but only to
                    the extent, that such untrue statement (or alleged untrue
                    statement) or omission (or alleged omission) is made in such
                    Registration Statement or prospectus in reliance upon and in
                    conformity with written information furnished to the Company
                    by such Selling Stockholder and stated to be for use in
                    connection with the offering of Registrable Securities.

               2.6.3 Indemnification Procedure. Promptly after receipt by an
                    indemnified party under this Section 2.6 of notice of the
                    commencement of any action which may give rise to a claim
                    for indemnification hereunder, such indemnified party will,
                    if a claim in respect thereof is to be made against an
                    indemnifying party under this Section 2.6, notify the
                    indemnifying party in writing of the commencement thereof
                    and generally summarize such action. The indemnifying party
                    shall have the right to participate in and to assume the
                    defense of such claim, and shall be entitled to select
                    counsel for the defense of such claim with the approval of
                    any parties entitled to indemnification, which approval
                    shall not be unreasonably withheld. Notwithstanding the
                    foregoing, the parties entitled to indemnification shall
                    have the right to employ separate counsel (reasonably
                    satisfactory to the indemnifying party) to participate in
                    the defense thereof, but the fees and expenses of such
                    separate counsel shall be at the expense of such indemnified
                    parties unless the named parties to such action or
                    proceedings include both the indemnifying party and the
                    indemnified parties and the indemnifying party or such
                    indemnified parties shall have been advised by counsel that
                    there are one or more legal defenses available to the
                    indemnified parties which are different from or additional
                    to those available to the indemnifying party (in which case,
                    if the indemnified parties notify the indemnifying party in
                    writing that they elect to employ separate counsel at the
                    reasonable expense of the indemnifying party, the
                    indemnifying party shall not have the right to assume the
                    defense of such action or proceeding on behalf of the
                    indemnified parties, it being understood, however, that the
                    indemnifying party shall not, in connection with any such
                    action or proceeding or separate or substantially similar or
                    related action or proceeding in the same jurisdiction
                    arising out of the same general allegations or
                    circumstances, be liable for the reasonable, documented fees
                    and expenses of more than one separate counsel at any time
                    for all indemnified parties, which counsel shall be
                    designated in writing by the Registered Holders of a
                    majority of the Registrable Securities).

               2.6.4 Contribution. If the indemnification provided for in this
                    Section 2.6 from an indemnifying party is unavailable to an
                    indemnified party hereunder in respect to any losses,
                    claims, damages, liabilities or expenses referred to herein,
                    then the indemnifying party, in lieu of indemnifying such
                    indemnified party, shall contribute to the amount paid or
                    payable by such indemnified party as a result of such
                    losses, claims, damages, liabilities or expenses in such
                    proportion as is appropriate to reflect the relative fault
                    of the indemnifying party and indemnified party in
                    connection with the statements or omissions which result in
                    such losses, claims, damages, liabilities or expenses, as
                    well as any other relevant equitable considerations. The
                    relative fault of such indemnifying party and indemnified
                    party shall be determined by reference to, among other
                    things, whether the untrue or alleged untrue statement of a
                    material fact or the omission or alleged omission to state a
                    material fact relates to information supplied by such
                    indemnifying party or indemnified party and the parties'
                    relative intent, knowledge, access to information supplied
                    by such indemnifying party or indemnified party and
                    opportunity to correct or prevent such statement or
                    omission. The amount paid or payable by a party as a result
                    of the losses, claims, damages, liabilities and expenses
                    referred to above shall be deemed to include any documented
                    legal or other fees or expenses reasonably incurred by such
                    party in connection with investigating or defending any
                    action, suit, proceeding or claim, or in collecting such
                    indemnity or reimbursement from the indemnifying party.

3.       Covenants of the Company.
         ------------------------

         The Company agrees to:

         (a)      Notify the holders of Registrable Securities included in a
                  Registration Statement (i) of the issuance by the Commission
                  of any stop order suspending the effectiveness of such
                  Registration Statement and (ii) upon learning of the
                  initiation of any proceedings for the purpose of suspending
                  such effectiveness, the existence of such proceedings. The
                  Company will make every reasonable effort to prevent the

                  to obtain the lifting thereof at the earliest possible time.

         (b)      If the Common Stock is then listed on a national securities
                  exchange, use its best efforts to cause the Registrable
                  Securities to be listed on such exchange. If the Common Stock
                  is not then listed on a national securities exchange, use its
                  best efforts to facilitate the reporting of the Registrable
                  Securities on Nasdaq.

         (c)      Take all other reasonable actions necessary to expedite and
                  facilitate disposition of the Registrable Securities by the
                  holders thereof pursuant to the Registration Statement.

         (d)      With a view to making available to the holders of Registrable
                  Securities the benefits of Rule 144 promulgated under the
                  Securities Act and any other rule or regulation of the
                  Commission that may at any time permit the Registered Holders
                  to sell securities of the Company to the public without
                  registration, the Company agrees to:

                  (i)      make and keep adequate current public information
                           with respect to the Company available, as those terms
                           are understood and defined in Rule 144, at all times
                           after 90 days after the effective date of the first
                           Registration Statement filed by the Company for the
                           offering of its securities to the general public;

                  (ii)     file with the Commission in a timely manner all
                           reports and other documents required of the Company
                           under the Securities Act and the Securities Exchange
                           Act of 1934 (the "1934 Act"); and

                    (iii) furnish to each holder of Warrant Shares, so long as
                         such holder of Warrant Shares owns any Warrant Shares,
                         forthwith upon written request (a) a written statement
                         by the Company as to whether it has complied with the
                         reporting requirements of Rule 144, the Securities Act
                         and the 1934 Act, (b) a copy of the most recent annual
                         or quarterly report of the Company and such other
                         reports and documents so filed by the Company and (c)
                         such other information as may be reasonably requested
                         and as is publicly available in availing the holders of
                         Shares of any rule or regulation of the Commission
                         which permits the selling of any such securities
                         without registration.

         (e)      Prior to the filing of a Registration Statement or any
                  amendment thereto (whether pre-effective or post-effective),
                  and prior to the filing of any prospectus or prospectus
                  supplement related thereto, the Company will provide each
                  Selling Stockholder with copies of all pages thereto, if any,
                  which reference such Selling Stockholder.

         (f)      If the Registration Statement relates to an underwritten
                  offering, enter into and perform its obligations under an
                  underwriting agreement, in usual and customary form,
                  including, without limitation, customary indemnification and
                  contribution obligations, with the underwriter's
                  representative.

         (g)      Make generally available to its security holders as soon as
                  practicable, but not later than forty five (45) days after the
                  close of the period covered thereby, the Company's financial
                  statements as filed with the Commission.

                    (h)  At the request of the Registered Holders who hold a
                         majority in interest of the Registrable Securities
                         being sold, furnish to the underwriters, if any, on the
                         date that Registrable Securities are delivered to the
                         underwriters for sale in connection with a registration
                         pursuant to this Appendix (i) an opinion, dated such
                         date, of the counsel representing the Company for the
                         purposes of such registration, in form and substance as
                         is customarily given to underwriters in an underwritten
                         public offering, addressed to the underwriters, and
                         (ii) a letter, dated such date, from the independent
                         certified public accountants of the Company, in form
                         and substance as is customarily given by independent
                         certified public accountants to underwriters in an
                         underwritten public offering, addressed to the
                         underwriters.

         (i)      Make available for inspection by any underwriters

                  sold pursuant to the Registration Statement and to enable such
                  certificates to be in such denominations and registered in
