                                 PROMISSORY NOTE
                                 ---------------

         FOR VALUE RECEIVED, ULTRALIFE BATTERIES, INC., a Delaware corporation
with offices at 2000 Technology Parkway, Newark, New York 14513 (the "Company"),
hereby promises to pay to the order of [NAME OF PAYEE], who has an address of
[ADDRESS OF PAYEE], or registered assigns ("Holder") the principal sum of
[REVISED PRINCIPAL AMOUNT] Dollars ($[REVISED PRINCIPAL AMOUNT]), or such lesser
principal amount to which this Amended and Restated Note shall have been
adjusted in accordance with the provisions of the Purchase Agreement (as defined
below), together with interest thereon calculated from the date hereof, in
accordance with the provisions of this Amended and Restated Note.

<PAGE>

         This Amended and Restated Note originated from a distribution and
splitting up of the subordinated convertible promissory note that was originally
issued on July 3, 2006 pursuant to the Asset Purchase Agreement, dated as of May
1, 2006 (the "Purchase Agreement"), by and among the McDowell Research, Ltd.,
Thomas Hauke, Earl Martin, Sr., James Evans, Frank Alexander, the Company and MR
Acquisition Corporation and the applicable provisions thereof, as may be amended
by the Settlement Agreement (as defined below), are hereby incorporated herein
in full by reference. The principal amount of this Amended and Restated Note
reflects adjustments that have been made in accordance with that certain
Settlement Agreement, dated as of the date hereof, by and among MRC Chargers,
Ltd., Frank Alexander, James Evans, Thomas Hauke, Earl Martin, Sr., Gloria
Martin, Lillian Hauke, the Company and McDowell Research Co., Inc. (the
"Settlement Agreement"). The Purchase Agreement contains terms governing the
rights of the Holder of this Amended and Restated Note and the Holder is
entitled to the benefits thereof. All capitalized terms used herein and not
otherwise defined shall have the meanings given thereto in the Purchase
Agreement.

         1. Interest. Except as otherwise expressly provided herein, interest
shall accrue from July 1, 2007 through and including the date hereof on the
original unpaid principal amount of [ORIGINAL PRINCIPAL AMOUNT] outstanding at
the rate of four percent (4%) per annum. Commencing on the day after the date
hereof, interest shall accrue on the unpaid principal amount of this Amended and
Restated Note outstanding until such time as payment thereof is actually
delivered to the Holder (including after acceleration, maturity or judgment) at
the rate of five percent (5%) per annum. All interest shall be calculated on the
basis of actual days elapsed divided by a 360 day year.

         Upon the occurrence of an Event of Default, at Holder's option interest
on the outstanding principal hereunder shall accrue at a rate per annum from
time to time equal to the rate of interest then in effect on this Amended and
Restated Note plus two percent (2%) per annum. Any increase in the interest rate
shall be in addition to the Holder's other available remedies.


         2. Payments. Interest shall be due and payable quarterly in arrears of
each year that this Amended and Restated Note is outstanding, commencing on
October 1, 2007 and continuing on the first day of each calendar quarter
thereafter until the principal hereof shall have become due and payable, and on
the Maturity Date hereof.
         All unpaid accrued interest and all outstanding principal shall be due
and payable in full on or before November 18, 2007 (the "Maturity Date").

                                      -2-
<PAGE>

         3. Voluntary Prepayments. This Amended and Restated Note may be prepaid
by the Company in whole or in part at any time without prior notice to Holder.

         4. Conversion Rights.

                  (a) The Holder may convert the outstanding principal amount of
this Amended and Restated Note (or a portion of such outstanding principal
amount as provided in Section 4(c)) into fully paid and nonassessable shares of
Common Stock of the Company (the "Conversion Shares") at any time, and from time
to time, prior to the time the outstanding principal amount of this Amended and
Restated Note is paid in full (subject to the notice periods and conversion
rights related thereto described elsewhere in this Amended and Restated Note),
at the Conversion Price (defined below) then in effect (collectively, the
"Conversion Rights"); provided, however, that if the closing price of the
Company's Common Stock as quoted on Nasdaq on the Closing Date is greater than
$12.00 per share, then the Holder will be precluded from exercising the
conversion rights under this Amended and Restated Note until the first
anniversary date of this Amended and Restated Note. The initial per share
conversion price (the "Conversion Price") shall be Fifteen and no/100 Dollars
($15.00). The Conversion Price is subject to adjustment as provided in Section
5.

                  (b) The provisions of this Amended and Restated Note that
apply to conversion of the outstanding principal amount of this Amended and
Restated Note also apply to a partial conversion of this Amended and Restated
Note. The Holder is not entitled to any rights of a holder of Conversion Shares
until the Holder has converted this Amended and Restated Note (or a portion
thereof) into Conversion Shares, and only to the extent that this Amended and
Restated Note is deemed to have been converted into Conversion Shares under this
Section 4.

                  (c) To convert all or a portion of this Amended and Restated
Note, the Holder must (a) complete and sign a notice of election to convert
substantially in the form of Exhibit I hereto (each, a "Conversion Notice"), (b)
surrender this Amended and Restated Note to the Company, and (c) furnish
appropriate endorsements or transfer documents if required by the Company. The
date on which the Holder satisfies all of such requirements is the conversion
date (the "Conversion Date"). As soon as practicable, and in any event within
ten (10) business days after the Conversion Date, the Company will deliver, or
cause to be delivered, to the Holder a certificate for the number of whole
Conversion Shares issuable upon such conversion and a check for any fractional
Conversion Share determined pursuant to Section 4(d). The person in whose name
the certificate for Conversion Shares is to be registered shall become the
stockholder of record on the Conversion Date and, as of the Conversion Date, the
rights of the Holder as to this Amended and Restated Note shall cease as to the
portion thereof so converted; provided, however, that no surrender of a Amended
and Restated Note on any date when the stock transfer books of the Company shall
be closed shall be effective to constitute the person entitled to receive the
Conversion Shares upon such conversion as the stockholder of record of such
Conversion Shares on such date, but such surrender shall be effective to
constitute the person entitled to receive such Conversion Shares as the
stockholder of record thereof for all purposes at the close of business on the
next succeeding day on which such stock transfer books are open; provided
further that such conversion shall be at the Conversion Price in effect on the
date that this Amended and Restated Note shall have been surrendered for
conversion, as if the stock transfer books of the Company had not been closed.

                                      -3-
<PAGE>

         In the case of a partial conversion of this Amended and Restated Note,
upon such conversion, the Company shall execute and deliver to the Holder, at
the expense of the Company, a new Amended and Restated Note in an aggregate
principal amount equal to the unconverted portion of the principal amount.


                  (d) No fractional Conversion Shares shall be issued upon
exercise of the Conversion Rights. Instead of any fractional Conversion Share
which would otherwise be issuable upon conversion of this Amended and Restated
Note, the Company shall calculate and pay a cash adjustment in respect of such
fraction (calculated to the nearest 1/100th of a share) in an amount equal to
the same fraction of the Conversion Price at the close of business on the
Conversion Date.

                  (e) The issuance of certificates for Conversion Shares upon
exercise of any of the Conversion Rights shall be made without charge to the
Holder for such certificates or for any tax in respect of the issuance of such
certificates, and such certificates shall be issued in the name of, or in such
names as may be directed by, the Holder; provided, however, that in the event
that certificates for Conversion Shares are to be issued in a name or names
other than the name of the Holder, such Amended and Restated Note, when
surrendered for conversion, shall be accompanied by an instrument of transfer,
in form satisfactory to the Company, duly executed by the Holder or his duly
authorized attorney; and provided further, moreover, that the Company shall not
be required to pay any tax which may be payable in respect of any transfer
involved in the issuance and delivery of any such certificates in a name or
names other than that of the Holder, and the Company shall not be required to
issue or deliver such certificates unless or until the person or persons
requesting the issuance thereof shall have paid to the Company the amount of
such tax or shall have established to the satisfaction of the Company that such
tax has been paid or is not applicable.

                  (f) The Company shall at all times reserve and keep available,
free from preemptive rights, out of its authorized and unissued Common Stock,
solely for the purpose of effecting the conversion of this Amended and Restated
Note, the full number of Conversion Shares then issuable upon the conversion in
full of this Amended and Restated Note.

         If the Company or an affiliate of the Company shall at any time after
the date hereof and prior to the conversion of this Amended and Restated Note in
full issue any rights to subscribe for shares of Common Stock or any other
securities of the Company or of such affiliate to all the stockholders of the
Company, the Holder of the unconverted portion of this Amended and Restated Note
shall be entitled, in addition to the shares of Common Stock or other securities
receivable upon the Conversion thereof, to receive such rights at the time such
rights are distributed to the other stockholders of the Company, to be
calculated on an as-converted basis.

                                      -4-

         5. Adjustments to Conversion Rights.

                  (a) General. In order to prevent dilution of the rights
granted under this Amended and Restated Note, the Conversion Price and the
number of Conversion Shares shall be subject to adjustment from time to time as
provided in this Section 5(a). It is the intention of the Company that the
Conversion Price shall at all times be the lower of (i) the Conversion Price on
the date of this Amended and Restated Note and (ii) the Conversion Price
determined by adjustment pursuant to the remainder of this Section 5(a). In the
event that at any time the Common Stock of the Company shall be exchanged for,
or changed into, a different kind and/or a number of shares of stock of the
Company or of another corporation by reason of a merger, consolidation, sale of
assets, recapitalization, reclassification, stock dividend, stock split-up or
combination of shares or otherwise, then, until any further adjustment is
required, there shall be issuable upon the conversion of this Amended and
Restated Note, in lieu of each share of Common Stock of the Company or of any
other stock theretofore issued pursuant to the provisions of this Amended and
Restated Note, the kind and/or number of shares of stock for which each share of
Common Stock of the Company or such other stock shall be so exchanged, or into
which each share of Common Stock of the Company or such other stock shall be so
changed and the Conversion Price shall be automatically adjusted to a new
Conversion Price as nearly equivalent as practicable to the adjustment in shares
of stock, if by reason of such merger, consolidation, recapitalization,
reclassification or otherwise the number of issued and outstanding shares of
Common Stock of the Company shall have been exchanged for or changed into such
new shares on other than a one-to-one basis. No adjustment in the Conversion
Price shall be made for cash dividends on the shares of Common Stock of the
Company or any other stock issued upon any conversion of this Amended and
Restated Note.

                  (b) Notices. Immediately upon any adjustment of the Conversion
Price, the Company shall give written notice thereof to the Holder, setting
forth in reasonable detail and certifying the calculation of such adjustment.

         6. Company Right to Compel Conversion. Notwithstanding any other
provisions of this Amended and Restated Note, the Company shall have the right,
at the Company's sole discretion, to compel the Holder to convert this Amended
and Restated Note at any time after the 30-day average closing price of the
Company's Common Stock exceeds Seventeen and 50/100 Dollars ($17.50) per share.
In such event, the Company shall provide the Holder with written notice of
conversion, setting forth the basis upon which the conditions to compel the
conversion were satisfied. Thereafter, this Amended and Restated Note shall only
represent the right to receive the Conversion Shares and any accrued but unpaid
interest.

         7. Subordination. The Holder agrees that the payment of the principal
of and the interest on this Amended and Restated Note is expressly subordinated
to the payment of all Senior Indebtedness, to the extent and subject to the
conditions set forth in this Section 7. As used herein, the term "Senior
Indebtedness" shall mean the principal of, the interest on and the premium, if
any, on all indebtedness of the Company for money borrowed by it from any
financial institution including banks, savings institutions or insurance
companies and similar institutional lenders, and all renewals, extensions and
refundings of any such indebtedness, whether such indebtedness shall have been
incurred prior to, on, or subsequent to the date hereof, unless by the terms of
the instruments creating or evidencing any such indebtedness it is provided that
such indebtedness is not to be considered Senior Indebtedness for the purpose of
this Amended and Restated Note.

                                      -5-
<PAGE>

                  (a) No interest or principal shall be paid on this Amended and
Restated Note without the consent of the holders of all outstanding Senior
Indebtedness if, at the date fixed herein for such interest or principal
payment, the Company shall be in default of payment of principal or interest
upon such Senior Indebtedness. In the event any payment of interest or principal
hereunder shall be prohibited pursuant to this Section 7(a), such payment shall
be deemed to be deferred until the cure of all defaults in payment of principal
or interest upon the Senior Indebtedness, and the payments hereon so deferred
shall immediately become due and payable upon the cure of such defaults.

                  (b) In the event of any dissolution, winding up, liquidation
or reorganization of the Company, whether in bankruptcy, insolvency or
receivership proceedings, or upon an assignment for the benefit of creditors or
in any other marshalling of the assets and liabilities of the Company the
holders of all Senior Indebtedness shall first be entitled to receive payment in
full of such Senior Indebtedness before the Holder shall be entitled to receive
any payment upon the principal of, the interest on, or the premium, if any, on
the indebtedness evidenced by this Amended and Restated Note. Upon any such
dissolution, winding up, liquidation or reorganization, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, to which the Holder would be entitled, except for the
provisions of this Section 7, shall be made by the liquidating trustee or agent
or such person making such payment or distribution, whether a trustee in
bankruptcy, a receiver or liquidating trustee or otherwise, directly to the
Holders of the Senior Indebtedness or their representatives or to the trustee or
trustees under any indenture or indentures under which any instruments
evidencing any such Senior Indebtedness may have been issued, ratably according
to the aggregate amounts remaining unpaid on account of the Senior Indebtedness
held or represented by each, to the extent necessary to pay in full all such
Senior Indebtedness remaining unpaid, after giving effect to all concurrent
payments or distributions with respect to such Senior Indebtedness.

                  (c) In the event that, notwithstanding the provisions of
Section 7(b), upon any such dissolution, or winding up, liquidation or
reorganization, any payment or distribution of assets of the Company of any kind
or character, whether in cash, property or securities, shall be received by the
Holder before all Senior Indebtedness is paid in full, such payment or
distribution shall be paid over to the holders of such Senior Indebtedness or
their representatives, ratably as aforesaid, for the application to the payment
of all Senior Indebtedness remaining unpaid until all such Senior Indebtedness
shall have been paid in full, after giving effect to any concurrent payment or
distribution with respect to such Senior Indebtedness.

                                      -6-
<PAGE>

                  (d) Subject to the payment in full of all Senior Indebtedness,
the Holder to the extent permitted by law, shall be subrogated to the rights of
each holder of Senior Indebtedness (to the extent of the payments or
distributions made to such holder pursuant to the provisions of Sections 7(b)
and 7(c)) to receive payments or distributions of assets of the Company
applicable to the Senior Indebtedness until the principal of, the interest on,
and the premium, if any, on this Amended and Restated Note shall be paid in
full, and each holder of Senior Indebtedness by accepting such payments or
distributions shall be deemed to have agreed to said subrogation. No payments or
distributions to the Senior Indebtedness pursuant to the provisions of Sections
7(b) and 7(c) shall, as between the Company, its creditors, other than the
holders of the Senior Indebtedness, and the Holder, be deemed to be a payment by
the Company to or on account of this Amended and Restated Note, the provisions
of this Section 7 being, and being intended, solely for the purpose of defining
the relative rights of the Holder, on the one hand, and the holders of the
Senior Indebtedness, on the other hand; and nothing contained in this Section 7
or elsewhere in this Amended and Restated Note is intended to or shall impair,
as between the Company, the Holder and the other creditors of the Company, other
than the holders of Senior Indebtedness, the obligations of the Company, which
is unconditional and absolute, to pay to the Holder as and when the same shall
become due and payable in accordance with the terms herein, or to affect the
relative rights of the Holder and the other creditors of the Company, other than
the holders of Senior Indebtedness, or to prevent the Holder from exercising all
of the remedies otherwise permitted by applicable law upon default as provided
for herein, subject to the rights, if any, under this Section 7 of the holders
of the Senior Indebtedness in respect of any cash, property or securities of the
Company received upon the exercise of any such remedy.

                  (e) In the event that this Amended and Restated Note shall be
declared due and payable before the Maturity Date because of the occurrence of a
default hereunder, the Company will give prompt notice in writing of such
happening to the holders of the Senior Indebtedness, and any and all Senior
Indebtedness shall forthwith become immediately due and payable upon demand by
the respective holders thereof regardless of the express maturity dates thereof

         Without limiting any of the foregoing, this Amended and Restated Note
is further subject to the Subordination and Intercreditor Agreement dated as of
July 3, 2006 among JP Morgan Chase Bank, N.A., Manufacturers and Traders Trust
Company, MC Chargers, Ltd., formerly named McDowell Research, Ltd., and the
Company, as amended by an Amendment to Subordination and Intercreditor Agreement
dated as of September __, 2007 among MRC Chargers, Ltd., Frank Alexander, James
Evans, Thomas Hauke, Earl Martin, Sr., Gloria Martin, Lillian Hauke and the
Company (as so amended, the "Subordination and Intercreditor Agreement"),
pursuant to which, among other things, this Amended and Restated Note and the
Company's obligations hereunder are subordinated in the manner and to the extent
set forth in the Subordination and Intercreditor Agreement to the prior payment
of certain obligations to the holders of Senior Obligations as defined therein.

         8. Events of Default.

         In the event that there shall be any Event of Default hereunder and
such Event of Default shall remain uncorrected or unremedied for a period of
more than thirty (30) days after the Company shall have received notice of such
Event of Default from the Holder, then the full unpaid principal amount of this
Amended and Restated Note, together with any accrued but unpaid interest, may,
at the option of the Holder, become immediately due and payable without further
notice by the Holder.

                  maturity, by mandatory prepayment, by call for redemption, by
                  declaration or otherwise;

                           (ii) the failure of the Company, to pay any
                  installment of interest or principal on Senior Indebtedness
                  when and as the same shall become due and payable, unless such
                  payment shall have been deferred or waived by the terms of the
                  instruments evidencing such Senior Indebtedness or by the
                  holder thereof;

                           (iii) the failure of the Company to observe and

                  Company contained herein or in the Asset Purchase Agreement;

                           (iv) failure of any representation or warranty made

                  (b) Upon the occurrence of an Event of Default which shall
remain uncorrected or unremedied for a period of more than thirty (30) days

Holder, the Holder shall at all times have the right to institute any suit,
action or proceeding, in equity or at law, for the enforcement of rights as
provided for herein, or in aid of the exercise of any right or power granted

                  (c) This Amended and Restated Note shall be the obligation of
the Company solely and there shall be no recourse had for the payment thereof or
interest thereon against any stockholder, officer or director of the Company,
either directly or through the Company, by reason of any matter prior to the
delivery of this Amended and Restated Note, or against any present or future
officer or director of the Company, all such liability being expressly released
by the Holder and by any subsequent holders hereof by the acceptance hereof and
