Gentlemen,

         Reference is made to the license agreement between C and T Co.
Incorporated ("C&T") and Axion Power Corporation ("Axion"), dated November 15,
2003, as amended. We have been advised that Tamboril Cigar Company ("Tamboril")
has recently acquired all issued and outstanding securities of Axion; other than
the contract rights held by C&T under the license agreement

         C&T hereby agrees to waive the share consideration specified in Section
3.1(b); the future royalty payments specified in Section 3.2; the conditional
merger rights specified in Section 12.1; and all of its right, title and
interest in and to the Technology Intellectual Property in exchange for
25,000,000 common stock purchase warrants. All such stock purchase warrants will
be exercisable at a price of $0.125 per share for a period of two years from the
original issue date and freely transferable to the individual stockholders of
C&T. The remaining physical assets, staff contracts and goodwill referred to in
Section 12.1 are expressly excluded from the current transaction.

         Tamboril and C&T will negotiate an acceptable amendment to the existing
Axion contract that provides for the final transfer of C&T's remaining physical
assets, staff contracts and goodwill to Tamboril upon the full payment of the
$1,794,000 purchase price specified in the amendment to the license agreement.
Moreover, C&T shall retain a purchase money security interest, and/or the
Canadian equivalent thereof, in the Technology Intellectual Property until all
such amounts have been paid in full and the stock of Tamboril is listed on
either the Nasdaq Stock Market or the American Stock Exchange.

Dear Mr. Filipenko,

                  Re: "Development & License Agreement" between
                    C & T Co Inc and Axion Power Corporation"

         This amends the above-mentioned License Agreement in the following
respects.

         In lieu of the license fee specified in Section 3.1, Axion shall
purchase 100% of the issued and outstanding stock of C&T for a total
consideration of ONE MILLION SEVEN HUNDRED and NINETY-FOUR THOUSAND US DOLLARS
($1,794,000). The purchase price for the foregoing securities shall be payable
according to the following schedule:

1.                US $100,000 was paid on September 22, 2003; 2. US $350,000
                  will be paid on or before December 31, 2003
3.                US $344,000 shall be paid in equal monthly payments of
                  $100,000 each payable on the first day of each month,
                  commencing on January 1, 2004; and
4.                US$1,000,000, together with any remaining balance of the
                  obligation in paragraphs 2 and 3 above shall be paid within 15
                  days after the Beta End Date, as defined in the agreed upon
                  Project Plan and Schedule.

         This letter constitutes an installment subscription agreement. C&T
shall not be required to issue any shares of its capital stock to Axion until
all of the payments set forth herein have been made. Axion shall not enjoy any
of the legal, equitable or other rights of a C&T shareholder, or be subject to
any of the legal burdens associated with such status, until the purchase price
has been paid in full and the C&T shares have actually been issued. If Axion
defaults on its obligation to make any of the foregoing installments and the
default is not cured within 60 days, then C&T shall, at its option, be entitled
to bring suit to enforce this agreement, or elect to terminate this agreement
and retain all amounts previously paid by Axion as liquidated damages.

         Please confirm that the foregoing reflects our understanding by
executing one copy of this letter.

                                                     Axion Power Corporation
