                                 PROMISSORY NOTE


                                                                  April 26, 2007
                                                           Boston, Massachusetts

         FOR VALUE RECEIVED, the undersigned Somanta Pharmaceuticals, Inc., a
Delaware corporation ("Borrower"), hereby promises to pay to the order of Access
Pharmaceuticals, Inc., a Delaware corporation ("Lender") at Lender's office at
2600 Stemmons Freeway, Suite 176, Dallas, TX 75207, upon the earlier of (i)
August 31, 2007 and (ii) the date of termination of the Agreement and Plan of
Merger, by and among Borrower, Lender and the other parties thereto, dated as of
April 18, 2007 (the "Merger Agreement"), but subject to the provisions
hereinafter set forth, the outstanding principal balance set forth on the Table
of Advances and Repayment of Principal attached hereto and incorporated herein,
and interest on the outstanding principal balance owing hereunder from time to
time, through and including the repayment date, in full at a rate per annum
equal to ten percent (10%). All capitalized terms used in this Note and not
otherwise defined herein shall have the same meanings herein as in that certain
Note Purchase Agreement, dated as of April 26, 2007 (as amended and in effect
from time to time, the "Note Purchase Agreement"), by and among Borrower and
Lender.

         Upon request by Borrower in writing as provided in the Note Purchase
Agreement, Lender may, in its sole and absolute discretion, advance amounts
requested by Borrower, whereupon Lender shall annotate the Table of Advances and
Repayment of Principal attached hereto to record such advance by increasing the
then outstanding principal balance by the amount of such advance. Borrower
hereby authorizes Lender to make such annotations and such annotations shall be
deemed to be amendments to this Note duly authorized and agreed by Borrower.

         At such time as all or any portion of the outstanding principal balance
owing hereunder is paid by Borrower, Borrower shall contemporaneously pay at
such time all then accrued but unpaid interest due hereunder. Upon such payment
by Borrower, Lender shall annotate the Table of Advances and Repayment of
Principal attached hereto to record such payment. Borrower hereby authorizes
Lender to make such annotations and such annotations shall be deemed to be
amendments to this Note duly authorized and agreed by Borrower. Any payments
made hereunder shall be applied (i) first to any outstanding expenses owed by
Borrower as provided in the Note Purchase Agreement, (ii) second to any accrued
but unpaid interest hereunder and (iii) third to repay outstanding principal. In
the event that any rate of interest required to be paid pursuant to this Note

<PAGE>
                                      -2-

exceeds the maximum rate legally enforceable, the rate of interest so required
to be paid shall be automatically reduced to the maximum rate legally
enforceable, and any excess paid over such maximum enforceable rate shall be
automatically credited to the outstanding principal balance hereof.

         This Note evidences borrowings under, and has been issued by Borrower
in accordance with the terms of, the Note Purchase Agreement. Lender and any
holder hereof is entitled to the benefits of the Note Purchase Agreement and the
other Loan Documents, and may enforce the agreements of Borrower contained
therein, and any holder hereof may exercise the respective remedies provided for
thereby or otherwise available in respect thereof, all in accordance with the
respective terms thereof.

         If any one or more of the following events (each an "Event of Default")
shall occur, then, in any such event, all amounts payable under this Note,
including unpaid interest accrued hereon, shall accelerate and become
automatically due and payable without notice or demand. Any amount unpaid after
the occurrence of an Event of Default shall accrue interest thereon at a rate
per annum equal to twelve percent (12%) per annum from the date thereof through
and including the date on which all such amounts are paid in full.

                  (a)      Borrower shall fail to make due and punctual payment
         of any interest or principal on this Note or any other cost or expense
         provided for herein or in any of the Loan Documents when the same shall
         become due and payable;

                  (b)      Borrower shall (i) apply for or consent to the
         appointment of a receiver, trustee or liquidator of any of its
         properties or assets, (ii) admit in writing its inability to pay its
         debts as they mature, (iii) make a general assignment for the benefit
         of its creditors, (iv) be adjudicated a bankrupt or insolvent, or (v)
         file a voluntary petition in bankruptcy, or a petition or an answer
         seeking reorganization or an arrangement with creditors to take
         advantage of any bankruptcy, reorganization, insolvency, readjustment
         of debt, dissolution or liquidation law or statute, or an answer
         admitting the material allegations of a petition filed against it in
         any proceeding under any such law;

                  (c)      An order, judgment or decree shall be entered, with
         or without the application, approval or consent of Borrower, by any
         court of competent jurisdiction, approving a petition seeking the
         reorganization or liquidation of Borrower or all or a substantial part
         of the properties or assets of Borrower, or appointing a receiver,
         trustee or liquidator of Borrower; or

                  (d)      Borrower shall breach any representation, warranty or
         covenant contained in any of the Loan Documents or in the Merger
         Agreement.

         Upon the occurrence of any Event of Default hereunder, Lender may, by
notice in writing to Borrower (a "Notice of Default"), declare all amounts owing
with respect to the Note Purchase Agreement, the Note and the other Loan
Documents to be accelerated and they shall thereupon forthwith become

<PAGE>

                                      -3-

immediately due and payable upon notice in writing to Borrower without
presentment, other demand, protest or other notice of any kind, all of which are
hereby expressly waived by Borrower.

         Upon giving to Borrower any Notice of Default, Lender, if owed any
amount with respect to the Loans, may proceed to protect and enforce its rights
by suit in equity, action at law or any other appropriate proceeding, whether
for the specific performance of any covenant or agreement contained in the Note
Purchase Agreement and the other Loan Documents or any instrument pursuant to
which the obligations to Lender are evidenced, including as permitted by
applicable law the obtaining of the ex parte appointment of a receiver, and, if
such amount shall have become due, by declaration or otherwise, proceed to
enforce the payment thereof or any other legal or equitable right of Lender. No
remedy herein conferred upon Lender or the holder of any Note is intended to be
exclusive of any other remedy and each and every remedy shall be cumulative and
shall be in addition to every other remedy given hereunder or now or hereafter
existing at law or in equity or by statute or any other provision of law.

         No delay or omission on the part of Lender or any holder hereof in
exercising any right hereunder shall operate as a waiver of such right or of any
other rights of Lender or such holder, nor shall any delay, omission or waiver
on any one occasion be deemed a bar or waiver of the same or any other right on
any future occasion.

         Borrower and every endorser and guarantor of this Note or the
obligation represented hereby assents to any extension or postponement of the
time of payment or any other indulgence, to any substitution, exchange or
release of collateral and to the addition or release of any other party or
person primarily or secondarily liable.

         THIS NOTE AND THE OBLIGATIONS OF BORROWER HEREUNDER SHALL FOR ALL
PURPOSES BE GOVERNED BY AND INTERPRETED AND CONSTRUED IN ACCORDANCE WITH THE
INTERNAL LAWS OF THE COMMONWEALTH OF MASSACHUSETTS, WITHOUT REGARD TO CONFLICTS
OF LAWS PRINCIPLES. BORROWER AGREES THAT ANY SUIT FOR THE ENFORCEMENT OF THIS
NOTE MAY BE BROUGHT IN THE COURTS OF THE COMMONWEALTH OF MASSACHUSETTS OR ANY
FEDERAL COURT SITTING THEREIN, AND CONSENTS TO THE NONEXCLUSIVE JURISDICTION OF
SUCH COURT AND THE SERVICE OF PROCESS IN ANY SUCH SUIT BEING MADE UPON BORROWER
BY MAIL AT THE ADDRESS SPECIFIED IN THE NOTE PURCHASE AGREEMENT. BORROWER HEREBY
WAIVES ANY OBJECTION THAT IT MAY NOW OR HEREAFTER HAVE TO THE VENUE OF ANY SUCH
SUIT OR ANY SUCH COURT OR THAT SUCH SUIT IS BROUGHT IN AN INCONVENIENT COURT.

any special, exemplary, punitive or consequential damages or any damages other
