Exhibit 10.3

                      LOAN AND STOCK SUBSCRIPTION AGREEMENT

      This Loan Agreement (the "Agreement") is made as of the 7th day of
October, 2003 among ULTRALIFE BATTERIES, INC., a Delaware corporation, having
its principle office at 2000 Technology Parkway, Newark, NY 14513, U.S.A.
("UBI") and ULTRALIFE TAIWAN, INC., a company organized and existing under the
laws of the Republic of China ("R.O.C."), having its principle office at No. 2-3
Industry E. Rd. II, Science-Based Industrial Park, Hsinchu, Taiwan, R.O.C. (the
"Company").

      The Company currently has an authorized capital of NT$2,500,000,000
divided into 250,000,000 shares of common stock at a par value of NT$10 each, of
which 194,062,000 shares are fully issued and outstanding. The Company intends
to first reduce its paid-in capital and then increase its paid-in capital by
issuing certain new shares of common stock. UBI desires to invest in the Company
by initially making a loan to the Company and then, upon repayment of that loan
under certain conditions, subscribing for certain shares of common stock to be
issued by the Company under such capital increase, all upon the terms and
conditions set forth in this Agreement.

      In consideration of the covenants and conditions set forth in this
Agreement, the parties agree as follows:

            1. Amount of Loan. UBI agrees to lend to the Company and the Company
agrees to borrow from UBI, a loan in the amount of US$2,350,000) (the "Loan").
UBI agrees to remit the Loan into the bank account designated by the Company on
October 7th, 2003. The Loan shall be evidenced by a promissory note in the form
attached hereto as Exhibit A.

            2. Reduction of Paid-in Capital. The Company shall take all
necessary corporate actions to reduce its paid-in capital from NT$1,940,620,000
to NT$776,248,000 by reducing NT$1,164,372,000 representing 116,437,200 shares
in proportion to the number of shares held by each of the shareholders of the
Company, namely, six hundred (600) shares shall be reduced for every one
thousand (1,000) old shares ("Contemplated Capital Reduction").

            3. Increase of Paid-in Capital. Immediately following the
comsummation of the Contemplated Capital Reduction, the Company shall take all
necessary corporate actions to increase its paid-in capital by at least
NT$300,000,000. ("Contemplated Capital Increase").

            4. Repayment of the Loan. The Company shall repay the Loan plus an
interest accrued at the interest rate of three percent (3%) per annum (i) at
least three (3) days prior to the record date of the Contemplated Capital
Increase; or (ii) immediately upon the request of UBI in the event that the
Contemplated Capital Increase or the Contemplated Capital Reduction has not been
consummated prior to March 1st, 2004. The repayment to be made by the Company
pursuant to this Agreement shall be made in US Dollars to a bank account
designated by UBI.

            5. Subscription to Shares. Subject to the repayment of the Loan in
accordance with Section 4(i) (rather than in accordance with Sections 4(ii) or 8
in which case UBI shall have no obligation to subscribe) and the terms and
conditions set forth herein, UBI agrees to subscribe to as many shares (the
"Shares") of common stock of the Company to be newly issued under the
Contemplated Capital Increase as the loan plus the accrued interest would buy at
the US dollar-New Taiwan dollar exchange rate at the day of the subscription.
The Company shall take any and all corporate actions to issue the Shares for
subscription by UBI, including, if necessary, obtaining waivers of any
preemptive rights with respect to the Shares.

            6. Closing. The closing of the share subscription (the "Closing")
shall be held at the time and place and in the manner to which the Company and
UBI may agree. At the Closing, UBI shall effect payment of the Subscription
Price through wire transfer to the bank account designated by the Company and
shall provide documentary evidence showing such payment. Upon receipt of such
documentary evidence, the Company shall deliver to UBI a certificate
acknowlegding receipt of payment of the Subscription Price and a certificate
confirming delivery of the share certificates representing the Shares within
seven (7) days after the Company amendment registration reflecting the
Contemplated Capital Increase has been approved by the Science-based Industrial
Park Administration ("SIPA").

such default shall not be cured within the period or periods of grace, if any,
specified in the instruments governing such obligations; or default shall occur
under any evidence of, or any indenture, lease, sublease, agreement or other
instrument governing such obligations, and such default shall continue for a

or obligations under the Loan Agreement.

      No failure by UBI to exercise, and no delay in exercising, any right or
remedy hereunder shall operate as a waiver thereof, nor shall any single or

other or further exercise thereof or the exercise of any other right or remedy.
The rights and remedies of UBI as herein specified are cumulative and not
exclusive of any other rights or remedies that such holder may otherwise have.

      No recission, waiver, forbearance, release or amendment of any provision

shall, to any extent, be held invalid or unenforceable, then only such provision
shall be deemed ineffective and the remainder of this Promissory Note shall not
be affected.

      This Promissory Note shall be governed by and construed in accordance with
the laws of the State of New York (but not its conflicts of law provisions). The
