Note on the date when due or within thirty (30) days thereafter, its rights to
the Investment Fees set forth in this SECTION 4.2 and its rights under ARTICLE V

Officer of the Company. The Quarterly Statement shall be in such form as the
parties hereto agree.

             (b) All calculations of the Gross Product Sales Amount, US Gross

             (c) The Company shall include payment for the Royalty, Investment
Fee and US Export Fee with the Quarterly Statement. Notwithstanding the
foregoing, if Xechem USA reasonably determines that the Company does not have
adequate working capital to fully pay the Royalty, the Investment Fee and the US
Export Fee, the Company shall only be required to pay such fees to the extent of
its excess available capital. Any Royalty, Investment Fee and US Export Fee not
paid by the Company hereunder shall accrue, without interest, and become payable
upon the Company obtaining sufficient working capital to pay Xechem USA the
amounts due to them hereunder.

             (d) The Company shall maintain complete and accurate financial
books and records in accordance with generally accepted accounting principles,
that fully and fairly reflect the transactions, properties, assets and

records as is reasonably necessary to verify the amounts due to them under this
Agreement. If Alembic or Xechem USA have any objections to the calculation of

their objections,



                                       6

specifying the amounts it believes to be inaccurate. The Company and Alembic or
Xechem USA, as the case may be, shall promptly meet to resolve any differences.
If the parties are not able to resolve their differences within thirty (30) days
of the date of the objection notice, the dispute shall be referred to an
independent auditor acceptable to both the parties, whose determination of the
amounts shall be final. The cost of the auditor shall be paid by the objecting
party; PROVIDED, HOWEVER, if such auditors refuse to resolve such dispute or
make such computation, then the dispute shall be resolved by an arbitration held
in New Brunswick, New Jersey, by an arbitration conducted in accordance with the
rules of the American Arbitration Association ("AAA"), by an arbitrator who is
an AAA member and who has been selected in accordance with its rules. In the
event the Company miscalculated any fee hereunder, the Company shall promptly
pay any deficiency to the appropriate party.

             (e) GUARANTEE BY XECHEM. Should the Company breach its obligation
to pay Investment Fees to Alembic as set forth in SECTION 4.2, Xechem USA shall
be responsible for payment of the fees otherwise payable to Alembic per SECTION
4.3.
