PROSPECTUS SUMMARY This summary highlights selected information and does not contain all of the information that is important to you. We urge you to read the entire Prospectus carefully and any information contained in or incorporated by reference in this Prospectus before you decide whether to buy our Common Stock. You should pay special attention to the risks of investing in our Common Stock discussed under Risk Factors below. Unless the context otherwise requires, references in this Prospectus to Ultralife, we, us, and our refer to Ultralife Batteries, Inc. and our subsidiaries. Ultralife We develop, manufacture and market a wide range of standard and customized primary and rechargeable lithium batteries for use in a wide array of applications and markets, including military, automotive telematics, safety and medical, and computers and communications. We believe that our proprietary technologies allow us to offer batteries that are ultra-thin, light weight and that generally achieve greater operating performance than other batteries currently available. We sell our products directly to original equipment manufacturers in the United States and abroad and have contractual arrangements with sales representatives who market our products on a commission basis in particular areas. We also distribute our products to domestic and international distributors and retailers that purchase our batteries for resale. We have obtained ISO 9001 certification for our lithium batteries manufacturing operations in Newark, New York and Abingdon, England. As of June 30, 2001, we had approximately 455 employees worldwide. We were formed in December 1990 as a Delaware corporation. In March 1991, we acquired certain technology and assets from Eastman Kodak Company relating to its 9-volt lithium manganese dioxide primary battery and in June 1994, as a result of the formation of our United Kingdom subsidiary and acquisition of certain battery-related assets, acquired a presence in Europe. In December 1998, we announced a joint venture to produce our polymer rechargeable batteries in Taiwan. Our principal executive office is located at 2000 Technology Parkway, Newark, New York 14513. Our telephone number is (315) 332-7100. RISK FACTORS An investment in shares of Common Stock offered hereby involves a high degree of risk. The following risk factors should be considered carefully in addition to the other information in this Prospectus before purchasing the Common Stock offered by this Prospectus. The following factors could cause actual results to differ materially from the matters described in the forward-looking statements, with material and adverse effects on the Company's business, operating results, financial condition and the value of Ultralife stock. History of Operating Losses; Uncertainty of Future Profitability We began operating our company in March 1991. During each year since 1991, we have had net operating losses. These losses have resulted mainly from the cost of researching, developing and manufacturing our products and general and administrative costs associated with operating our company. We cannot assure that we will generate an operating profit or achieve profitability in the future. Uncertainty of Market Acceptance of Advanced Rechargeable Batteries Although we have begun volume production of our rechargeable batteries, our advanced rechargeable batteries have not yet achieved wide acceptance in the market. We cannot assure that a - 3 -

market will ever accept our advanced rechargeable batteries. The introduction of new products is subject to the inherent risks of unforeseen delays and the time necessary to achieve market success for any individual product is uncertain. If volume production and/or market penetration of our advanced rechargeable batteries is delayed for any reason, our competitors may introduce emerging technologies or improve existing technologies which could have a material adverse effect on our business, financial condition and results of operations. Dependence on OEM Relationships and their products for Sale of Advanced Rechargeable Batteries We will continue to promote market demand for, and awareness of, our advanced rechargeable batteries. We will accomplish this partly through the development of relationships with OEMs that manufacture products which require the performance characteristics of our advanced rechargeable batteries. The success of any such relationship depends upon the general business condition of the OEM and our ability to produce our advanced rechargeable batteries at the quality and cost and within the period required by such OEMs. Our failure to develop a sufficient number of relationships with OEMs could have a material adverse effect on our business, financial condition and results of operations. A substantial portion of our business will depend upon the success of products sold by OEMs that use our batteries. Therefore, our success is substantially dependent upon the acceptance of the OEMs' products in the marketplace. We are subject to many risks beyond our control that influence the success or failure of a particular product manufactured by an OEM, including, competition faced by the OEM in its particular industry; market acceptance of the OEM's product; the engineering, sales, marketing and management capabilities of the OEM; technical challenges unrelated to our technology or products faced by the OEM in developing its products; and, the financial and other resources of the OEM. Risks Relating to Growth and Expansion Rapid growth of our advanced rechargeable battery business or other segments of our business may significantly strain our management, operations and technical resources. If we are successful in obtaining rapid market growth of our advanced rechargeable batteries, we will be required to deliver large volumes of quality products to our customers on a timely basis at a reasonable cost to those customers. We cannot assure, however, that our business will rapidly grow or that our efforts to expand our manufacturing and quality control activities will be successful or that we will be able to satisfy commercial scale production requirements on a timely and cost-effective basis. We will also be required to continue to improve our operations, management and financial systems and controls. Our failure to manage our growth effectively could have an adverse effect on our business, financial condition and results of operations. Competition; Technological Obsolescence The primary and rechargeable battery industry is characterized by intense competition with a large number of companies offering or seeking to develop technology and products similar to ours. We are subject to competition from manufacturers of traditional rechargeable batteries, such as nickel-cadmium batteries, from manufacturers of rechargeable batteries of more recent technologies, such as nickel-metal hydride, lithium-ion liquid electrolyte and lithium-ion solid-polymer batteries, as well as from companies engaged in the development of batteries incorporating new technologies. Manufacturers of nickel-cadmium and nickel-metal hydride batteries include Eveready, Sanyo Electric Co. Ltd., Sony Corp., Toshiba Corp., Matsushita Electric Industrial Co., Ltd. and Duracell International, Inc. Manufacturers of lithium-ion liquid electrolyte batteries currently include Saft-Soc des ACC, Sony Corp., Toshiba Corp., Matsushita Electric Industrial Co., Ltd., Sanyo Electric Co. Ltd. and Duracell International, Inc. Valence Technology, Inc., Lithium Technology Corporation, and Yuasa-Exide, Inc. have developed prototype solid-polymer batteries and are constructing commercial-scale manufacturing facilities. We also compete with large and small manufacturers of alkaline, carbon-zinc, seawater, high rate and primary batteries as well as other manufacturers of lithium batteries. We cannot assure that we - 4 -

will successfully compete with these manufacturers, many of which have substantially greater financial, technical, manufacturing, distribution, marketing, sales and other resources. Many companies with substantially greater resources than ours are developing a variety of battery technologies, including liquid electrolyte lithium and solid electrolyte lithium batteries, which are expected to compete with our technology. Other companies undertaking research and development activities of solid-polymer batteries have already developed prototypes and are constructing commercial scale production facilities. If these companies successfully market their batteries before the introduction of our products, there could be a material adverse effect on our business, financial condition and results of operations. The market for our products is characterized by changing technology and evolving industry standards, often resulting in product obsolescence or short product lifecycles. Although we believe that our batteries, particularly our 9-volt and advanced rechargeable batteries, are comprised of state-of-the-art technology, there can be no assurance that competitors will not develop technologies or products that would render our technology and products obsolete or less marketable. Dependence on Key Personnel Because of the specialized, technical nature of our business, we are highly dependent on certain members of our management, marketing, engineering and technical staff. If we lose the services or these members, this could have a material adverse effect on our business, financial condition and results of operations. In addition to developing manufacturing capacity so that we can produce high volumes of our advanced rechargeable batteries, we must attract, recruit and retain a sizeable workforce of technically competent employees. Our ability to pursue effectively our business strategy will depend upon, among other factors, the successful recruitment and retention of additional highly skilled and experienced managerial, marketing, engineering and technical personnel. We cannot assure that we will be able to retain or recruit this type of personnel. Safety Risks; Demands of Environmental and Other Regulatory Compliance Components of our batteries contain certain elements that are known to pose safety risks. Our primary battery products incorporate lithium metal, which when it reacts with water may cause fires if not handled properly. In addition to a December 1996 fire at our Abingdon, England facility, a fire occurred August 1997 at our Newark, New York facility and fires occurred in July 1994 and September 1995 at our Abingdon, England facility, each of which temporarily interrupted certain manufacturing operations in a specific area of these facilities. Although we incorporate safety procedures in our research, development and manufacturing processes that are designed to minimize safety risks, we cannot assure that more accidents will not occur. Although we currently carry insurance policies which cover loss of our plant and machinery, leasehold improvements, inventory and business interruption, any accident, whether at our manufacturing facilities or from the use of our products, may result in significant production delays or claims for damages resulting from injuries. These types of losses could have a material adverse effect on our business, financial condition and results of operations. National, state and local laws impose various environmental controls on the manufacture, storage, use and disposal of lithium batteries and/or of certain chemicals used in the manufacture of lithium batteries. Although we believe that our operations are in substantial compliance with current environmental regulations and that, except as noted below, there are no environmental conditions that will require material expenditures for clean-up at our present or former facilities or at facilities to which it has sent waste for disposal, there can be no assurance that changes in such laws and regulations will not impose costly compliance requirements on we or otherwise subject it to future liabilities. Moreover, state and local governments may enact additional restrictions relating to the disposal of lithium batteries used by our customers which could have a material adverse effect on our business, financial condition and results of operations. In addition, the U.S. Department of Transportation and certain foreign regulatory agencies that consider lithium to be a hazardous material regulate the transportation of batteries which contain lithium metal. We currently ship our lithium batteries in accordance with regulations established by the U.S. Department of Transportation. There can be no assurance that additional or modified regulations relating to the manufacture, transportation, storage, use and disposal of materials used to - 5 -

manufacture our batteries or restricting disposal of batteries will not be imposed or how these regulations will affect us or our customers. In connection with our purchase/lease of our Newark, New York facility in 1998, a consulting firm performed a Phase I and II Environmental Site Assessment which revealed the existence of contaminated soil and ground water around one of our buildings. We retained an engineering firm which estimated that the cost of remediation should be in the range of $230,000. This cost, however, is merely an estimate and the cost may in fact be much higher. In February 1998, we entered into an agreement with a third party which provides that we and this third party will retain an environmental consulting firm to conduct a supplemental Phase II investigation to verify the existence of the contaminants and further delineate the nature of the environmental concern. The third party agreed to reimburse us for fifty percent of the cost of correcting the environmental concern on the Newark property. We cannot assure that we will not face claims resulting in substantial liability which would have a material adverse effect on our business, financial condition and results of operations in the period in which such claims are resolved. Limited Sources of Supply Certain materials we use in our products are available only from a single or a limited number of suppliers. Additionally, we may elect to develop relationships with a single or limited number of suppliers for materials that are otherwise generally available. Although we believe that alternative suppliers are available to supply materials that could replace materials currently used by us and that, if necessary, we would be able to redesign our products to make use of such alternatives, any interruption in our supply from any supplier that serves as our sole source could delay product shipments and have a material adverse effect on our business, financial condition and results of operations. Although we have experienced interruptions of product deliveries by sole source suppliers, these interruptions have not had a material adverse effect on our business, financial condition and results of operations. We cannot guarantee that we will not experience a material interruption of product deliveries from sole source suppliers. Dependence on Proprietary Technologies Our success depends more on the knowledge, ability, experience and technological expertise of our employees than on the legal protection of our patents and other proprietary rights. We claim proprietary rights in various unpatented technologies, know-how, trade secrets and trademarks relating to our products and manufacturing processes. We cannot guarantee the degree of protection these various claims may or will afford, or that our competitors will not independently develop or patent technologies that are substantially equivalent or superior to our technology. We protect our proprietary rights in our products and operations through contractual obligations, including nondisclosure agreements with certain employees, customers, consultants and strategic partners. There can be no assurance as to the degree of protection these contractual measures may or will afford. We, however, have had patents issued and patent applications pending in the U.S. and elsewhere. We cannot assure (i) that patents will be issued from any pending applications, or that the claims allowed under any patents will be sufficiently broad to protect our technology, (ii) that any patents issued to us will not be challenged, invalidated or circumvented, or (iii) as to the degree or adequacy of protection any patents or patent applications may or will afford. If we are found to be infringing third party patents, there can be no assurance that we will be able to obtain licenses with respect to such patents on acceptable terms, if at all. Our failure to obtain necessary licenses could delay product shipment or the introduction of new products, and costly attempts to design around such patents could foreclose the development, manufacture or sale of our products. Dependence on Technology Transfer Agreements Our research and development of advanced rechargeable battery technology and products utilizes internally-developed technology, acquired technology and certain patents and related technology licensed by us pursuant to non-exclusive, technology transfer agreements. There can be no assurance that our competitors will not develop, independently or through the use of similar technology transfer agreements, - 6 -

rechargeable battery technology or products that are substantially equivalent or superior to the technologies and products currently under research and development by us. Risks Related to China Joint Venture Program In July 1992, we entered into several agreements related to the establishment of a manufacturing facility in Changzhou, China, for the production and distribution in and from China of 2/3A lithium primary batteries. Changzhou Ultra Power Battery Co., Ltd., a company organized in China ("China Battery"), purchased from us certain technology, equipment, training and consulting services relating to the design and operation of a lithium battery manufacturing plant. China Battery was required to pay approximately $6.0 million to us over the first two years of the agreement, of which approximately $5.6 million has been paid. We have been attempting to collect the balance due under this contract. China Battery has indicated that it will not make these payments until certain contractual issues have been resolved. Due to China Battery's questionable willingness to pay, we wrote off in fiscal 1997 the entire balance owed to us as well as our investment aggregating $805,000. Since China Battery has not purchased technology, equipment, training or consulting services from us to produce batteries other than 2/3 A lithium batteries, we do not believe that China Battery has the capacity to become our competitor. We do not anticipate that the manufacturing or marketing of 2/3 A lithium batteries will be a substantial portion of our product line in the future. However, in December 1997, China Battery sent to us a letter demanding reimbursement of an unspecified amount of losses they have incurred plus a refund for certain equipment that we sold to China Battery. We have attempted to initiate negotiations to resolve the dispute. However, an agreement has not yet reached. Although China Battery has not taken any additional steps, there can be no assurance that China Battery will not further pursue such a claim which, if successful, would have a material adverse effect on our business, financial condition and results of operations. We believe that such a claim is without merit. Ability to Insure Against Losses Because certain of our primary batteries are used in a variety of security and safety products and medical devices, we may be exposed to liability claims if such a battery fails to function properly. We maintain what we believe to be sufficient liability insurance coverage to protect against potential claims; however, there can be no assurance that the liability insurance will continue to be available, or that any such liability insurance would be sufficient to cover any claim or claims. Possible Volatility of Stock Price Future announcements concerning us or our competitors, including technological innovations or commercial products, litigation or public concerns as to the safety or commercial value of one or more of our products, may cause the market price of our Common Stock to fluctuate substantially for reasons which may be unrelated to operating results. These fluctuations, as well as general economic, political and market conditions, may have a material adverse effect on the market price of our Common Stock. FORWARD-LOOKING STATEMENTS This Prospectus, including information contained in documents that are incorporated by reference in this Prospectus, contains forward-looking statements, as that term is defined by federal securities laws, that relate to the financial condition, results of operations, plans, objectives, future performance and business of Ultralife. These statements are frequently preceded by, followed by or include the words believes, expects, anticipates, estimates or similar expressions. We have based these forward-looking statements on our current expectations and projections about future events. The statements contained in this Prospectus relating to matters that are not historical facts are forward-looking statements that involve risks and uncertainties, including future demand for our products and services, the successful commercialization of our advanced rechargeable batteries, general economic conditions, government and - 7 -

environmental regulation, competition and customer strategies, technological innovations in the primary and rechargeable battery industries, changes in our business strategy or development plans, capital deployment, business disruptions, including those caused by fire, raw materials, supplies and other risks and uncertainties, certain of which are beyond our control. In addition to these risks, in the section of this Prospectus entitled Risk Factors, we have summarized a number of the risks and uncertainties that could affect the actual outcome of the forward-looking statements included in this Prospectus. We advise you not to place undue reliance on these forward-looking statements in light of the material risks and uncertainties to which they are subject. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may differ materially from those described herein as anticipated, believed, estimated or expected. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. USE OF PROCEEDS We will not receive any of the proceeds from the sale of the shares of Common Stock by the selling stockholders. To the extent, however, that the warrants are exercised through payment of the exercise price in cash, rather than a cashless exercise, we will receive the proceeds of those exercises. We have agreed to bear all expenses, other than selling commissions and fees and expenses of counsel and other advisors to the selling stockholders, in connection with the registration of the shares being offered. SELLING STOCKHOLDERS The following Table A sets forth the number of shares of Common Stock owned by each of the selling stockholders who subscribed for shares of our Common Stock in our recent private placement. None of these selling stockholders has had a material relationship with us within the past three years other than as a result of the ownership of our Common Stock. Because the selling stockholders may offer all or some of the Common Stock which they hold pursuant to the offering contemplated by this Prospectus, and because there are currently no agreements, arrangements or understandings with respect to the sale of any of the shares, no estimate can be given as to the amount of shares that will be held by the selling stockholders after completion of this offering. The shares offered by this Prospectus may be offered from time to time by the selling stockholders named below or by pledgees, donees, transferees or other successors in interest who receive the shares as a gift, partnership distribution or other non-sale related transfer. - 8 -

PLAN OF DISTRIBUTION We will receive no proceeds from this offering. The shares offered by this Prospectus may be sold by the selling stockholders (including those holding stock as a result of the future exercise of the warrants) from time to time in transactions in the over-the-counter market, in negotiated transactions, or in a combination of such methods of sale, at fixed prices which may be changed, at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. The selling stockholders (including those holding stock as a result of the future exercise of the warrants) may effect such transactions by selling the shares to or through broker-dealers, and such broker-dealers may receive compensation in the form of discounts, concessions or commissions from the selling stockholders (including those holding stock as a result of the future exercise of the warrants) and/or the purchasers of the shares for whom such broker-dealers may act as agents or to whom they sell as principals, or both. This compensation might be in excess of customary commissions. The shares we are offering may be sold either pursuant to this Registration Statement or pursuant to Rule 144 issued by the SEC under the Securities Act of 1933. In order to comply with the securities laws of certain states, if applicable, the shares will be sold in such jurisdictions only through registered or licensed brokers or dealers. In addition, in certain states the shares may not be sold unless they have been registered or qualified for sale in the applicable state or an exemption from the registration or qualification requirement is available and is complied with. The selling stockholders (including those holding stock as a result of the future exercise of the warrants) and any broker-dealers or agents that participate with the selling stockholders (including those holding stock as a result of the future exercise of the warrants) in the distribution of the shares may be deemed to be "underwriters" within the meaning of the Securities Act of 1933, and any commissions received by them and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under federal law. Under applicable federal rules and regulations, any person engaged in the distribution of our Common Stock may not simultaneously engage in market making activities with respect to our Common Stock for a period of two business days prior to the commencement of such distribution. In addition, and without limiting the foregoing, each selling stockholder will be subject to applicable provisions of the Securities Exchange Act of 1934 and the rules and regulations of the SEC promulgated thereunder. These rules include, without limitation, Rules 10b-6 and 10b-7, which may limit the timing of purchases and sales of shares of our Common Stock by the selling stockholders (including those holding stock as a result of the future exercise of the warrants).

INDEMNIFICATION OF DIRECTORS AND OFFICERS With respect to indemnification of directors and officers, Section 145 of the Delaware General Corporation Law ("DGCL") provides that a corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding, if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person's conduct was unlawful. Under this provision of the DGCL, the termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in or not opposed to the best interests of the corporation, and with respect to any criminal action or proceeding, had reasonable cause to believe that the person's conduct was unlawful. Furthermore, the DGCL provides that a corporation shall have the power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper. The Company's Restated Certificate of Incorporation (the "Certificate of Incorporation") and By-laws, as amended (the "By-laws") provide for limitation of the liability of directors to the Company and its stockholders and for indemnification of directors, officers, employees and agents of the Company, respectively, to the maximum extent permitted by the DGCL. II-1

The Certificate of Incorporation provides that directors are not liable to the Company or its stockholders for monetary damages for breaches of fiduciary duty as a director, except for liability (a) for any breach of the director's duty of loyalty to the Company or its stockholders, (b) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (c) for dividend payments or stock repurchases in violation of Delaware law, or (d) for any transaction from which the director derived any improper personal benefit. The By-laws include provisions by which the Company will indemnify its officers and directors and other persons against expenses, judgments, fines and amounts paid in settlement with respect to threatened, pending or completed suits or proceedings against such persons by reason of serving or having served the Company as officers, directors or in other capacities, except in relation to matters with respect to which such persons shall be determined not to have acted in good faith, lawfully or in the best interests of the Company. With respect to matters to which the Company's officers, directors, employees, agents or other representatives are determined to be liable for misconduct or negligence in the performance of their duties, the By-laws provide for indemnification only to the extent that the Company determines that such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company.

UNDERTAKINGS The undersigned Registrant hereby undertakes (subject to the proviso contained in Item 512(a) of Regulation S-K): (1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement: (i) to include any prospectus required by section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflect in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. II-2

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. The undersigned Registrant hereby undertakes to supplement the prospectus, after expiration of the subscription period, to set forth the results of the subscription offer, the transactions by the underwriters during the subscription period, the amount of unsubscribed securities to be purchased by the underwriters, and the terms of any subsequent reoffering thereof. If any public offering by the underwriters is to be made on terms different from those set forth on the cover page of the prospectus, a post-effective amendment will be filed to set forth the terms of such offering. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue. The undersigned registrant hereby undertakes to deliver or cause to be delivered the prospectus, to each person to whom the prospectus is sent or given, the latest annual report, to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specially incorporated by referred in the prospectus to provide such interim financial information. II-3

SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that is has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized in the City of Newark, State of New York, on this 17th day of August, 2001.

               ULTRALIFE BATTERIES, INC. SHARE PURCHASE AGREEMENT

This SHARE PURCHASE AGREEMENT (this "Agreement"), is made and entered into as of
July 19, 2001, by and among ULTRALIFE BATTERIES, INC., a Delaware corporation
(the "Company"), and the purchasers listed on Schedule A attached hereto
(collectively, the "Purchasers" and individually, a "Purchaser").

1.    AUTHORIZATION OF SALE OF THE SHARES

Subject to the terms and conditions of this Agreement, the Company has
authorized the sale of up to 1,200,000 shares (the "Shares") of common stock,
par value $.10 per share (the "Common Stock"), of the Company.

2.    AGREEMENT TO SELL AND PURCHASE THE SHARES

      2.1 Purchase and Sale

Subject to the terms and conditions of this Agreement, each Purchaser severally
agrees to purchase, and the Company agrees to sell and issue to each Purchaser,
at the Closing (as defined below) that number of Shares set forth opposite such
Purchaser's name on Schedule A attached hereto.

2.2      Purchase Price

The purchase price of each Share shall be $6.25 (the "Per Share Price"). The
Company shall not, during the period beginning on the date of this Agreement and
ending ninety (90) days after the Closing Date (as defined below), without
adjusting the price per Share hereunder accordingly, (i) sell Shares at a price
per Share of less than the Per Share Price, or (ii) grant or issue options,
warrants or any other securities that can be converted into, or otherwise
exchanged for, shares of the Company's common stock at a conversion, exchange or
exercise price per Share of less than the Per Share Price. In the event the
Company shall, during the period beginning on the date of this Agreement and
ending ninety (90) days after the Closing Date, sell any shares of the Company's
common stock at, or grant or issue any instruments that can be converted into or
otherwise exchanged for the Company's common stock (the "Subsequent Sale")
exercisable at, a price per Share (the "Subsequent Purchase Price") of less than
the Per Share Price, the Company shall, within ten (10) business days of the
Subsequent Sale, pay to the Purchaser a cash amount equal to the number of
Shares times the difference between the Per Share Price and the Subsequent
Purchase Price.

3.    DELIVERY OF THE SHARES AT THE CLOSING

      (a) The completion of the purchase and sale of the Shares (the "Closing")
shall occur at the offices of Harter, Secrest & Emery LLP, counsel to the
Company, at Rochester, New York at 9:00 a.m. local time on June 28, 2001 or such
other time and date as may be agreed by the parties (the "Closing Date").


(b) At the Closing, the Company shall authorize its transfer agent (the "Transfer Agent") to issue to each Purchaser one or more stock certificates registered in the name of such Purchaser, or in such nominee name(s) as designated by such Purchaser in writing, representing the number of Shares set forth in Section 2 above and bearing an appropriate legend referring to the fact that the Shares were sold in reliance upon the exemption from registration provided by Section 4(2) of the Securities Act of 1933, as amended (the "Securities Act"), and Rule 506 under the Securities Act.

however, that the Company will not be liable in any such case to the extent that any such loss, claim, damage, liability or expense arises out of or is based upon (i) an untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, the Prospectus or any amendment or supplement of the Registration Statement or Prospectus in reliance upon and in conformity with written information furnished to the Company by or on behalf of the Purchaser expressly for use in the Registration Statement or the Prospectus, or (ii) the failure of such Purchaser to comply with the covenants and agreements contained in Sections 5.2 or 7.2 of this Agreement respecting resale of the Shares, or (iii) the inaccuracy of any representations made by such Purchaser in this Agreement or (iv) any untrue statement or omission of a material fact required to make such statement not misleading in any Prospectus that is corrected in any subsequent Prospectus that was delivered to the Purchaser before the pertinent sale or sales by the Purchaser. 7.3.2 Indemnification by the Purchaser Each Purchaser will severally and not jointly indemnify and hold harmless the Company, each of its directors, each of its officers who signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Securities Act, against any losses, claims, damages, liabilities or expenses to which the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person may become subject, under the Securities Act, the Exchange Act, or any other federal or state statutory law or regulation, or at common law or otherwise (including in settlement of any litigation, if such settlement is effected with the written consent of such Purchaser, which consent shall not be unreasonably withheld) insofar as such losses, claims, damages, liabilities or expenses (or actions in respect thereof as contemplated below) arise out of or are based upon (i) any failure on the part of such Purchaser to comply with the covenants and agreements contained in Sections 5.2 or 7.2 of this Agreement respecting the sale of the Shares or (ii) the inaccuracy of any representation made by such Purchaser in this Agreement or (iii) any untrue or alleged untrue statement of any material fact contained in the Registration Statement, the Prospectus, or any amendment or supplement to the Registration Statement or Prospectus, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in the Registration Statement, the Prospectus, or any amendment or supplement thereto, in reliance upon and in conformity with written information furnished to the Company by or on behalf of such Purchaser expressly for use therein; provided, however, that the Purchaser shall not be liable for any such untrue or alleged untrue statement or omission or alleged omission of which the Purchaser has delivered to the Company in writing a correction before the occurrence of the transaction from which such loss was incurred, and the Purchaser will reimburse the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person for any legal and other expense reasonably incurred by the Company, each of its directors, each of its officers who signed the Registration Statement or controlling person in connection with investigating, defending, settling, compromising or paying any such loss, claim, damage, liability, expense or action. 7.3.3 Indemnification Procedure

(a) Promptly after receipt by an indemnified party under this Section 7.3 of notice of the threat or commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 7.3, promptly notify the indemnifying party in writing of the claim; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party for contribution or otherwise under the indemnity agreement contained in this Section 7.3 or to the extent it is not prejudiced as a result of such failure. (b) In case any such action is brought against any indemnified party and such indemnified party seeks or intends to seek indemnity from an indemnifying party, the indemnifying party will be entitled to participate in, and, to the extent that it may wish, jointly with all other indemnifying parties similarly notified, to assume the defense thereof with counsel reasonably satisfactory to such indemnified party; provided, however, if the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be a conflict between the positions of the indemnifying party and the indemnified party in conducting the defense of any such action or that there may be legal defenses available to it or other indemnified parties that are different from or additional to those available to the indemnifying party, the indemnified party or parties shall have the right to select separate counsel to assume such legal defenses and to otherwise participate in the defense of such action on behalf of such indemnified party or parties. Upon receipt of notice from the indemnifying party to such indemnified party of its election so to assume the defense of such action and approval by the indemnified party of counsel, the indemnifying party will not be liable to such indemnified party under this Section 7.3 for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof unless: (i) the indemnified party shall have employed such counsel in connection with the assumption of legal defenses in accordance with the proviso to the preceding sentence (it being understood, however, that the indemnifying party shall not be liable for the expenses of more than one separate counsel, approved by such indemnifying party representing all of the indemnified parties who are parties to such action) or (ii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of commencement of action, in each of which cases the reasonable fees and expenses of counsel shall be at the expense of the indemnifying party. Notwithstanding the provisions of this Section 7.3, the Purchaser shall not be liable for any indemnification obligation under this Agreement in excess of the amount of gross proceeds received by the Purchaser from the sale of the Shares. 7.3.4 Contribution If the indemnification provided for in this Section 7.3 is required by its terms but is for any reason held to be unavailable to or otherwise insufficient to hold harmless an indemnified party under this Section 7.3 in respect to any losses, claims, damages, liabilities or expenses referred to in this Agreement, then each applicable indemnifying party shall contribute to the amount paid

or payable by such indemnified party as a result of any losses, claims, damages, liabilities or expenses referred to in this Agreement (a) in such proportion as is appropriate to reflect the relative benefits received by the Company and the Purchaser from the sale of Common Stock or (b) if the allocation provided by clause (a) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (a) above but the relative fault of the Company and the Purchaser in connection with the statements or omissions or inaccuracies in the representations and warranties in this Agreement that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The respective relative benefits received by the Company on the one hand and each Purchaser on the other shall be deemed to be in the same proportion as the amount paid by such Purchaser to the Company pursuant to this Agreement for the Shares purchased by such Purchaser that were sold pursuant to the Registration Statement bears to the difference (the "Difference") between the amount such Purchaser paid for the Shares that were sold pursuant to the Registration Statement and the amount received by such Purchaser from such sale. The relative fault of the Company and each Purchaser shall be determined by reference to, among other things, whether the untrue or alleged statement of a material fact or the omission or alleged omission to state a material fact or the inaccurate or the alleged inaccurate representation or warranty relates to information supplied by the Company or by such Purchaser and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include, subject to the limitations set forth in Section 7.3.3, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim. The provisions set forth in Section 7.3.3 with respect to the notice of the threat or commencement of any threat or action shall apply if a claim for contribution is to be made under this Section 7.3.4; provided, however, that no additional notice shall be required with respect to any threat or action for which notice has been given under Section 7.3 for purposes of indemnification. The Company and each Purchaser agree that it would not be just and equitable if contribution pursuant to this Section 7.3 were determined solely by pro rata allocation (even if the Purchaser were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in this paragraph. Notwithstanding the provisions of this Section 7.3, no Purchaser shall be required to contribute any amount in excess of the amount by which the Difference exceeds the amount of any damages that such Purchaser has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Purchasers' obligations to contribute pursuant to this Section 7.3 are several and not joint. 7.4 Termination of Conditions and Obligations The restrictions imposed by Section 5 or this Section 7 upon the transferability of the Shares shall cease and terminate as to any particular number of the Shares upon the passage of two years

from the Closing Date or at such time as an opinion of counsel satisfactory in form and substance to the Company shall have been rendered to the effect that such conditions are not necessary in order to comply with the Securities Act. 7.5 Information Available From the date of this Agreement through the date the Registration Statement covering the resale of Shares owned by any Purchaser is no longer effective, the Company will furnish to such Purchaser: (a) as soon as practicable after available (but in the case of the Company's Annual Report to Shareholders, within 90 days after the end of each fiscal year of the Company), one copy of (i) its Annual Report to Shareholders (which Annual Report shall contain financial statements audited in accordance with generally accepted accounting principles by a national firm of certified public accountants); (ii) if not included in substance in the Annual Report to Shareholders, its Annual Report on Form 10-K; (iii) its quarterly reports on Form 10-Q; and (iv) a full copy of the particular Registration Statement covering the Shares (the foregoing, in each case, excluding exhibits); (b) upon the request of the Purchaser, a reasonable number of copies of the Prospectus to supply to any other party requiring the Prospectus. 7.6 Rule 144 Information Until the earlier of (i) the date on which the Shares may be resold by the Purchasers without registration and without regard to any volume limitations by reason of Rule 144(k) under the Securities Act or any other rule of similar effect or (ii) all of the Shares have been sold pursuant to the Registration Statement or Rule 144 under the Securities Act or any other rule of similar effect, the Company shall file all reports required to be filed by it under the Securities Act, the Rules and Regulations and the Exchange Act and shall take such further action to the extent required to enable the Purchasers to sell the Shares pursuant to Rule 144 under the Securities Act (as such rule may be amended from time to time). 7.7 Stock Option Matters and Prohibition on Toxics (a) To the extent the Company has not already done so, the Company shall, within thirty (30) days of the Closing Date, adopt such amendments to, with respect to (i) and (ii) below, the Company's stock option plans and By-laws, and, with respect to (iii) and (iv) below, the Company's By-laws (together, the "Stock Option Plan and By-law Amendments") to provide that, unless approved by the holders of a majority of the shares present and entitled to vote at a duly convened meeting of shareholders, the Company shall not:

(i) grant any stock options with an exercise price that is less than 100% of the fair market value of the underlying stock on the date of grant; (ii) reduce the exercise price of any stock option granted under any existing or future stock option plan; (iii) sell or issue any security of the Company convertible, exercisable or exchangeable into shares of Common Stock, having a conversion, exercise or exchange price per share which is subject to downward adjustment based on the market price of the Common Stock at the time of conversion, exercise or exchange of such security into Common Stock (except for appropriate adjustments made to give effect to any stock splits or stock dividends); or (iv) enter into (a) any equity line or similar agreement or arrangement; or (b) any agreement to sell Common Stock (or any security convertible, exercisable or exchangeable into shares of Common Stock ("Common Stock Equivalent")) at a per share price (or, with respect to a Common Stock Equivalent, at a conversion, exercise or exchange price, as the case may be ("Equivalent Price")) that is fixed after the execution date of the agreement, whether or not based on any predetermined price-setting formula or calculation method. Notwithstanding the foregoing, however, a price protection clause shall be permitted in an agreement for sale of Common Stock or Common Stock Equivalent, if such clause provides for an adjustment to the price per share of Common Stock or, with respect to a Common Stock Equivalent, to the Equivalent Price (provided that such price or Equivalent Price is fixed on or before the execution date of the agreement) (the "Fixed Price") in the event that the Company, during the period beginning on the date of the agreement and ending no later than 90 days after the closing date of the transaction, sells shares of Common Stock or Common Stock Equivalent to another investor at a price or Equivalent Price, as the case may be, below the Fixed Price. (v) The Stock Option Plan and By-law Amendments may not be further amended or repealed without the affirmative vote of the holders of a majority of the shares present and entitled to vote at a duly convened meeting of shareholders. Upon the adoption of the Stock Option Plan and By-law Amendments, the Company shall promptly furnish a copy of such amendments to the Purchasers. The Company agrees that, prior to the adoption of the Stock Option Plan and By-law Amendments by all necessary corporate action of the Company as described above, the Company shall not conduct any of the actions specified in (i), (ii), (iii) or (iv) above of this Section 7.7. 8. LEGAL FEES AND OTHER TRANSACTION EXPENSES 8.1.1 [For the Purchaser known as State of Wisconsin Investment Board]: At the Closing, the Company agrees to pay a flat fee of $5,000 to the State of Wisconsin Investment Board for their legal and other transaction expenses (whether internal or external) arising in connection with the transactions contemplated by this Agreement. [For the remaining Purchasers listed on Schedule "A" attached hereto and made a part hereof.]: The Company and each Purchaser shall be responsible for their own legal and other transaction expenses (whether internal or external) arising in connection with the transactions contemplated by this Agreement.

Wainwright & Co., Inc., the placement agent, a fee in respect of the sale of the Shares to certain of the Purchasers that will consist of $200,000 and a five-year warrant to purchase for $6.25 per share up to that number of shares of the Company's Common Stock as equals 10% of the Shares purchased pursuant to this Agreement. The Purchasers also acknowledge that the Company intends to pay to Kimelman & Baird LLC a cash fee equal to 5% of the amount raised through the sale of the Shares to certain of the Purchasers affiliated with Kimelman & Baird LLC.

EXHIBIT A [LOGO OMITTED] HARTER SECREST & EMERY LLP -------------------------- ATTORNEYS AND COUNSELORS July 19, 2001 To the Purchasers of Common Stock of Ultralife Batteries, Inc. Listed on Exhibit A Attached Hereto Ladies and Gentlemen: We have acted as counsel to Ultralife Batteries, Inc., a Delaware corporation (the "Company"), in connection with the issuance and sale to you of 1,090,000 shares of the Company's Common Stock (the "Shares") pursuant to the Ultralife Batteries, Inc. Share Purchase Agreement dated as of July 19, 2001 between the Company and each of the Purchasers listed on Exhibit A hereto (the "Agreement"). We are rendering this opinion pursuant to Section 3(d)(iii) of the Agreement. Except as otherwise defined herein, capitalized terms used but not defined herein shall have the respective meanings given to them in the Agreement. In connection with this opinion, we have examined and relied upon the representations and warranties as to factual matters contained in and made pursuant to the Agreement by the various parties as well as contained in certificates of officers of the Company, and originals or copies, certified to our satisfaction, of such records, documents, certificates, opinions, memoranda and other instruments as in our judgment are necessary or appropriate to enable us to render the opinions expressed below. Where we render an opinion "to the best of our knowledge" or concerning an item "known to us" or our opinion otherwise refers to our knowledge, it is based solely upon (i) an inquiry of attorneys within this firm who have performed legal services for the Company and (ii) such other investigation, if any, that we specifically set forth herein. Based upon and reliance on the foregoing, and subject to the assumptions and qualifications hereinafter set forth, we are of the opinion that: 1. The Company is a corporation duly incorporated and, as of June 26, 2001, validly existing and in good standing under the laws of the State of Delaware. The Company is duly licensed or qualified and in good standing as a foreign corporation authorized to do business in all jurisdictions where the character of the property owned or leased by it, or the nature of the activities conducted by it, make such licensing or qualification necessary, except where failure to so qualify would not have a material adverse effect on the Company's results of operations. As

HARTER SECREST & EMERY LLP -------------------------- ATTORNEYS AND COUNSELORS Page 2 of June 18, 2001, the Company is duly qualified to do business and in good standing as a foreign corporation under the laws of the State of New York. The foregoing opinions are given solely on the basis of certificates of appropriate state agencies in the states of Delaware and New York. In determining appropriate state agencies we have relied, without further inquiry, on the advice of CT Corporation System and Accelerated Information Document & Filing, Inc. as to those agencies from which certificates should be received. The foregoing opinion is limited to the meaning ascribed to such certificates by each applicable state agency. 2. The Company has the corporate power and authority to own or lease its properties and operate its business as now conducted, and to execute, deliver and perform its obligations under the Agreement. 3. The Company's execution and delivery of, and its performance of its obligations under the Agreement have been duly authorized by all necessary corporate action on the part of the Company, and the Agreement has been duly executed and delivered by the Company. 4. The Agreement is the valid and binding obligation of the Company, enforceable against the Company in accordance with its terms. 5. The Company's execution and delivery of, and the Company's performance of its obligations under, the Agreement do not on this date (a) conflict with or result in a breach of any provision of the Restated Certificate of Incorporation, as amended, or By-laws, as amended, of the Company, or (b) violate any existing law, rule, regulation or ordinance applicable to the Company and affecting the enforceability of the Agreement, or (c) to our actual knowledge without independent investigation (i) result in a breach of any of the provisions of, or constitute a default under, or result in the creation or imposition of a lien, charge or encumbrance upon any of the assets of the Company pursuant to any agreement or instrument to which the Company is a party or by which the Company or its assets is bound (assuming the laws of each jurisdiction governing such agreement or instrument are the same as the laws of the State of New York) or (ii) violate any existing judgment, order, writ, injunction or decree expressly applicable to the Company. 6. To our actual knowledge, without independent investigation, there is no action, suit or proceeding pending, or overtly threatened by written communication, against the Company or expressly affecting it or its assets, where an unfavorable decision, ruling or finding would materially adversely affect the validity or enforceability of the Agreement, or the business, operations, properties, or financial condition of the Company except as disclosed in the Schedule of Exceptions to the Agreement and in the Company's Form 10-Q for the quarter ended March 31, 2001. 7.

EXHIBIT B SCHEDULE OF EXCEPTIONS SECTION 4.6 Environmental. As disclosed in the Company's Form 10-K for the fiscal year ended June 30, 2000, in connection with the Company's purchase/lease of its Newark, New York facility, a consulting firm performed a Phase I and II Environmental Site Assessment which revealed the existence of contaminated soil around one of the Company's buildings. The Company retained an engineering firm which estimated that the cost of remediation should be in the range of $230,000; however, there can be no assurance that this will be the case. In February 1998, the Company entered into an agreement with a third party which provided that the Company and the third party would retain an environmental consulting firm to verify the existence of the contaminants and further delineate the nature of the environmental concern. A voluntary investigation work plan of the site to fully characterize the nature and extent of the contamination that was found during a Phase II investigation is underway. The third party has agreed to reimburse the Company for 50% of the cost associated with remediating the environmental concern. There can be no assurance that the Company will not face claims resulting in substantial liability which would have a material adverse effect on the Company's business, financial condition and results of operations in the period in which such claims are resolved. Section 4.9 No Action. As disclosed in the Company's Report on Form 10-Q for the quarter ended March 31, 2001, in August 1998, the Company, its Directors, and certain underwriters were named as defendants in a complaint filed in the United States District Court for the District of New Jersey by certain shareholders, purportedly on behalf of a class of shareholders, alleging that the defendants, during the period April 30, 1998 through June 12, 1998, violated various provisions of the federal securities laws in connection with an offering of 2,500,000 shares of the Company's Common Stock. The complaint alleged that the Company's offering documents were materially incomplete, and as a result misleading, and that the purported class members purchased the Company's Common Stock at artificially inflated prices and were damaged thereby. Upon motion made on behalf of the Company, the Court dismissed the shareholder action, without prejudice, allowing the complaint to be refiled. The shareholder action was subsequently refiled, asserting substantially the same claims as in the prior pleading. The Company again moved to dismiss the complaint. By Opinion and Order dated September 28, 2000, the Court dismissed the action, this time with prejudice, thereby barring plaintiffs from any further amendments to their complaint and directing that the case be closed. Plaintiffs filed a Notice of Appeal to the Third Circuit Court of Appeals, the parties submitted their briefs, and oral argument, originally scheduled for the week of May 21, 2001, has been suspended pending further discussions with the Court. The Company believes that the litigation is without merit and will continue to defend it vigorously. The amount of alleged damages, if any, cannot be quantified, nor can the outcome of this litigation be predicted. Accordingly, management cannot determine whether the ultimate resolution of this litigation could have a material adverse effect on the Company's financial position and results of operations.

WARRANT AGREEMENT, dated as of July 20, 2001, between Ultralife Batteries Inc., a Delaware corporation (the "Company"), H.C. Wainwright & Co., Inc. (the "Agent") and the individual affiliates of the Agent identified on Schedule A attached hereto (the "Wainwright Affiliates") (the Agent and the Wainright Affiliates collectively referred to as the "Warrantholders"). WHEREAS, the Company proposes to issue to the Warrantholders Common Stock Purchase Warrants as hereinafter described (the "Warrants"), to purchase up to 109,000 shares of common stock, par value $.10 per share (the "Common Stock") of the Company (the Common Stock issuable on exercise of the Warrants being referred to herein as the "Warrant Shares"), as set forth on Schedule A, in consideration of the services rendered by the Agent in connection with the Company's private placement of certain shares of its Common Stock. NOW, THEREFORE, in consideration of the premises and the mutual agreements herein set forth, the parties hereto agree as follows: SECTION 1. Warrant Certificates. The certificates evidencing the Warrants (the "Warrant Certificates") to be delivered pursuant to this Agreement shall be in substantially the form set forth in Exhibit A attached hereto. SECTION 2. Execution of Warrant Certificates. Warrant Certificates shall be signed on behalf of the Company by its President or its Chief Financial Officer and by its Secretary or an Assistant Secretary and shall be dated the date of signature by the Company. The Company may deem and treat the registered holder(s) of the Warrant Certificates as the absolute owner(s) thereof (notwithstanding any notation of ownership or other writing thereon made by anyone), for all purposes, and the Company shall not be affected by any notice to the contrary. SECTION 3. Registration of Transfers and Exchanges. (a) The Company shall from time to time, subject to the limitations of Section 4, register the transfer of any portion or all of any outstanding Warrant Certificate upon the records to be maintained by it for that purpose, upon surrender thereof duly endorsed or accompanied (if so required by it) by a written instrument or instruments of transfer in form satisfactory to the Company, duly executed by the registered holder or holders thereof or by the duly appointed legal representative thereof or by a duly authorized attorney. Upon any such registration of transfer, a new Warrant Certificate shall be issued to the transferee(s) and the surrendered Warrant Certificate shall be cancelled by the Company. (b) The Agent agrees, and by receiving a Warrant Certificate, each Warrant-holder agrees, that prior to any proposed transfer of the Warrant or of the Warrant Shares, if such transfer is not made pursuant to an effective Registration Statement under the Securities Act of 1933, as amended (the "Act"), or an opinion of counsel that the Warrants or Warrant Shares may be transferred without registration under the Act, the Warrantholder will deliver to the Company: (1) an investment covenant reasonably satisfactory to the Company signed by the proposed transferee; (2) an agreement by such transferee to the impression of the restrictive investment legend set forth below on the Warrant or the Warrant Shares; (3) an agreement by such transferee to be bound by the provisions of this Agreement. The Agent agrees and each Warrantholder agrees that each certificate representing Warrant Shares will bear a legend in substantially the following form unless at the time the Warrant is exercised there is an effective Registration Statement under the Act with respect to the Warrant Shares:

"The securities evidenced or constituted hereby have been acquired for investment and have not been registered under the Securities Act of 1933, as amended. Such securities may not be sold, transferred, pledged or hypothecated unless the registration provisions of said Act have been complied with or unless the Company has received an opinion of counsel reasonably satisfactory to the Company that such registration is not required." (c) Subject to the terms of this Agreement, Warrant Certificates may be exchanged at the option of the holder(s) thereof, when surrendered to the Company at its principal office, which is currently located at the address listed in Section 12 hereof, for another Warrant Certificate or other Warrant Certificates of like tenor and representing in the aggregate a like number of Warrants. Any holder desiring to exchange a Warrant Certificate shall deliver a written request to the Company, and shall surrender, duly endorsed or accompanied (if so required by the Company) by a written instrument or instruments of transfer in form satisfactory to the Company, the Warrant Certificate or Certificates to be so exchanged. Warrant Certificates surrendered for exchange shall be cancelled by the Company. SECTION 4. Terms of Warrants; Exercise of Warrants. (a) The initial exercise price per share at which Warrant Shares shall be purchasable upon the exercise of the Warrants (the "Exercise Price") shall be equal to $6.25 per share. Each Warrant shall be initially exercisable for one share of Common Stock. Each Warrant Certificate shall represent that number of Warrants set forth on the Warrant Certificate. Subject to the terms of this Agreement, each Warrantholder shall have the right, from the date of issuance of the Warrants until 5:00 p.m., New York City time on July 20, 2006 (the "Exercise Period"), to receive from the Company the number of fully paid and nonassessable Warrant Shares which the Warrantholder may at the time be entitled to receive on exercise of the Warrants and payment of the Exercise Price then in effect for such Warrant Shares. If not exercised prior to 5:00 p.m., New York City time, on July 20, 2006, the Warrants shall become void and all rights thereunder and all rights in respect thereof under this Agreement shall cease as of such time. (b) The Warrants may be exercised upon surrender to the Company at its principal office, which is currently located at the address listed in Section 12 hereof, of the Warrant Certificate or Certificates evidencing the Warrants to be exercised with the form of election to purchase on the reverse thereof duly filled in and signed, which signature shall be guaranteed by a participant in a recognized Signature Guarantee Medallion Program and such other documentation as the Company may reasonably request, and upon payment to the Company for the account of the Company of the Exercise Price which is set forth in the form of Warrant Certificate attached hereto as Exhibit A as adjusted as herein provided, for the number of Warrant Shares in respect of which such Warrants are then exercised. Subject to the provisions of Section 4(c) hereof, payment of the aggregate Exercise Price shall be made in cash or by certified or official bank check payable to the order of the Company in New York Clearing House Funds. (c) Subject to the time limitations set forth in subsections (i) and (ii) below, if at the time a Warrantholder exercises any Warrants hereunder, the Company does not have in effect a current Registration Statement with the Securities and Exchange Commission (the "Commission") under the Securities Act of 1933, as amended (the "Act"), the Warrantholder may choose one of the following, but not both: (i) At any time after the initial effectiveness of the Registration Statement contemplated by Section 8(b), rather than paying the aggregate Exercise Price in cash or by certified or official bank check in accordance with provisions of Section 4(b) above, the Warrantholder shall be entitled to effect a "cashless exercise" as described in this Section 4(c)(i). For the purposes of this Section 4(c)(i), a "cashless exercise" shall mean an exercise of a Warrant where the payment of the Exercise Price is made with Warrant Shares issuable upon exercise of a Warrant, which Warrant Shares shall be 2

valued at the Fair Market Value (as defined below) of the Common Stock on the date of exercise. For purposes hereof, the "Fair Market Value" of the Common Stock shall mean the closing price of the Common Stock on the NASDAQ Stock Market (or any successor stock market) for the day on which the notice of exercise is sent or delivered. In the event of a Cashless Exercise, the number of Warrant Shares issuable to the Warrantholder shall be determined using the following formula: X = Y (A - B)/A where: X = the number of Warrant Shares to be issued to the Warrantholder on exercise: Y = the number of Warrant Shares purchasable under the Warrants surrendered A = the Fair Market Value of the Common Stock on the date of exercise; and B = the then current Exercise Price of the Warrant; or (ii) At any time after October 18, 2001, upon payment of the aggregate Exercise Price in cash or by certified or official bank check in accordance with the provisions of Section 4(b) above, the Warrantholder shall be entitled to receive from the Company liquidated damages in an amount equal to 0.25% of the total Exercise Price paid by the holder of the Warrant Shares upon exercise of the Warrants for each week that the Registration Statement is not effective, which amount shall be paid to the Warrantholder at the end of each such week. (d) Subject to the provisions of Section 5 hereof, upon such surrender of Warrants and payment of the Exercise Price, the Company shall issue and cause to be delivered within five business days to and in such name or names as the Warrantholder may designate a certificate or certificates for the number of full Warrant Shares issuable upon the exercise of such Warrants; provided, however, that if any consolidation, merger or lease or sale of assets is proposed to be effected by the Company as described in subsection (c) of Section 9 hereof, or a tender offer or an exchange offer for shares of Common Stock of the Company shall be made, upon such surrender of the Warrants and payment of the Exercise Price as aforesaid, the Company shall, as soon as possible, but in any event not later than two business days thereafter, issue and cause to be delivered the full number of Warrant Shares issuable upon the exercise of such Warrants in the manner described in this sentence. Such certificate or certificates shall be deemed to have been issued and any person so designated to be named therein shall be deemed to have become a holder of record of such Warrant Shares as of the date of the surrender of such Warrants and payment of the Exercise Price. (e) The Warrants shall be exercisable, at the election of the holders thereof, either in full or from time to time in part and, in the event that a certificate evidencing Warrants is exercised in respect of fewer than all of the Warrant Shares issuable on such exercise at any time prior to the date of expiration of the Warrants, a new certificate evidencing the remaining Warrants will be issued. The Company may assume that any Warrant presented for exercise is permitted to be so exercised under applicable law and shall have no liability for acting in reliance on such assumption. (f) All Warrant Certificates surrendered upon exercise of Warrants shall be cancelled by the Company. (g) The Company shall keep copies of this Agreement and any notices given or received hereunder available for inspection by the Warrantholders with reasonable prior written notice during normal business hours at its office. SECTION 5. Payment of Taxes. The Company will pay all documentary stamp taxes attributable to the initial issuance of Warrant Shares upon the exercise of Warrants; provided, however, that the Company shall not be required to pay any tax or taxes which may be payable in respect of any transfer involved in the issue of any Warrant Certificates or any certificates for Warrant Shares in a name other than that of the registered holder of a Warrant Certificate surrendered upon the exercise of a Warrant, and the Company shall not be required to issue or deliver such Warrant Certificates unless or until the person 3

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. SECTION 6. Mutilated or Missing Warrant Certificates. In case any Warrant Certificate shall be mutilated, lost, stolen or destroyed, the Company may in its discretion issue, in exchange and substitution for and upon cancellation of the mutilated Warrant Certificate, or in lieu of and substitution for the Warrant Certificate lost, stolen or destroyed, a new Warrant Certificate of like tenor and representing an equivalent number of Warrants, but only upon receipt of evidence satisfactory to the Company of such loss, theft or destruction of such Warrant Certificate and indemnity, if requested, also satisfactory to the Company. Applicants for such substitute Warrant Certificates shall also comply with such other reasonable regulations and pay such other reasonable charges as the Company may prescribe. SECTION 7. Reservation of Warrant Shares. (a) The Company will at all times reserve and keep available, free from preemptive rights, out of the aggregate of its authorized but unissued Common Stock or its authorized and issued Common Stock held in its treasury, for the purpose of enabling it to satisfy any obligation to issue Warrant Shares upon exercise of Warrants, the maximum number of shares of Common Stock which may then be deliverable upon the exercise of all outstanding Warrants. (b) The Company or, if appointed, the transfer agent for the Common Stock (the "Transfer Agent") and every subsequent transfer agent for any shares of the Company's capital stock issuable upon the exercise of any of the rights of purchase aforesaid will be irrevocably authorized and directed at all times to reserve such number of authorized shares as shall be required for such purpose. The Company will keep a copy of this Agreement on file with the Transfer Agent and with every subsequent transfer agent for any shares of the Company's capital stock issuable upon the exercise of the rights of purchase represented by the Warrants. The Company will supply such Transfer Agent with duly executed certificates for such purposes. The Company will furnish such Transfer Agent a copy of all notices of adjustments and certificates related thereto, transmitted to each Warrantholder pursuant to Section 12 hereof. (c) Before taking any action which would cause an adjustment pursuant to Section 9 hereof to reduce the Exercise Price below the then par value (if any) of the Warrant Shares, the Company will take any corporate action which may, in the opinion of its counsel (which may be counsel employed by the Company), be necessary in order that the Company may validly and legally issue fully paid and nonassessable Warrant Shares at the Exercise Price as so adjusted. (d) The Company covenants that all Warrant Shares which may be issued upon exercise of Warrants will, upon payment of the Exercise Price therefor and issue, be fully paid, nonassessable, free of preemptive rights and free from all taxes, liens, charges and security interests with respect to the issue thereof. SECTION 8. Obtaining Stock Exchange Listings; Registration of Warrant Shares. (a) The Company will from time to time take all action which may be necessary so that the Warrant Shares, immediately upon their issuance upon the exercise of Warrants, will be listed on the principal securities exchanges and markets within the United States of America, if any, on which other shares of Common Stock are then listed. (b) The Company agrees with the Agent and each Warrantholder to include the Warrant Shares in the Registration Statement (as defined in that certain Share Purchase Agreement dated July 19, 2001 (the "Purchase Agreement")) by and among the Company and the purchasers identified on Schedule A to that Purchase Agreement required by Section 7 of the Purchase Agreement, and the provisions set forth in Section 7 of the Purchase Agreement as they relate to the Registration Statement shall apply with full 4

force and effect to the Warrantholders who shall, for purposes of that Section 7 be deemed Purchasers, and the Warrant Shares to be included in the Registration Statement, except that with respect to the Warrant Shares, the obligation of the Company to keep the Registration Statement effective shall expire on the earlier of (i) the date on which all of the Warrant Shares have been sold pursuant to the Registration Statement or (ii) July 20, 2007. The indemnification provisions of Section 7.3 of the Purchase Agreement are hereby incorporated by reference with each Warrantholder being deemed a Purchaser for purposes of the provisions of that Section 7.3. SECTION 9. Adjustment of Exercise Price and Number of Warrant Shares Issuable. The Exercise Price and the number of Warrant Shares issuable upon the exercise of Warrants are subject to adjustment from time to time upon the occurrence of the events enumerated in this Section 9. With respect to any Warrant, no adjustment to the Exercise Price or to the number of Warrant Shares issuable upon exercise shall be made for any event enumerated in this Section 9 if the date as to which the Company committed to undertake such event was prior to such Warrant's issuance. For purposes of this Section 9, "Common Stock" means shares now or hereafter authorized of any class of common stock of the Company and any other stock of the Company, however designated, that has the right (subject to any prior rights of any class or series of preferred stock) to participate in any distribution of the assets or earnings of the Company without limit as to per share amount. (a) Adjustment for Change in Capital Stock. If the Company: (1) pays a dividend or makes a distribution on its Common Stock in shares of its Common Stock; (2) subdivides its outstanding shares of Common Stock into a greater number of shares; (3) combines its outstanding shares of Common Stock into a smaller number of shares; (4) makes a distribution on its Common Stock in shares of its capital stock other than Common Stock; or (5) issues by reclassification of its Common Stock any shares of its capital stock; then the Warrants in effect immediately prior to such action shall be proportionately adjusted so that the holder of any Warrant thereafter exercised may receive the aggregate number and kind of shares of capital stock of the Company which he would have owned immediately following such action if such Warrant had been exercised immediately prior to such action. The adjustment shall become effective immediately after the record date in the case of a dividend or distribution and immediately after the effective date in the case of a subdivision, combination or reclassification. Such adjustment shall be made successively whenever any event listed above shall occur. (b) When De Minimis Adjustment May Be Deferred. No adjustment in the Exercise Price need be made unless the adjustment would require an increase or decrease of at least 1% in the Exercise Price. Any adjustments that are not made shall be carried forward and taken into account in any subsequent adjustment. All calculations under this Section 9 shall be made to the nearest cent or to the nearest 1/100th of a share, as the case may be. 5

(c) Reorganization of Company. If the Company consolidates or merges with or into, or transfers or leases all or substantially all its assets to (each, a "Reorganization Transaction"), any person, upon consummation of such transaction the Warrants shall automatically become exercisable for the kind and amount of securities, cash or other assets which the holder of the Warrants would have owned immediately after the consolidation, merger, transfer or lease if the holder had exercised the Warrants immediately before the effective date of the Reorganization Transaction. (d) When Issuance or Payment May Be Deferred. In any case in which this Section 9 shall require that an adjustment in the Exercise Price be made effective as of a record date for a specified event, the Company may elect to defer until the occurrence of such event issuing to the holder of any Warrant exercised after such record date the Warrant Shares and other capital stock of the Company, if any, issuable upon such exercise over and above the Warrant Shares and other capital stock of the Company, if any, issuable upon such exercise on the basis of the Exercise Price; provided, however, that the Company shall deliver to such holder a due bill or other appropriate instrument evidencing such holder's right to receive such additional Warrant Shares and other capital stock upon the occurrence of the event requiring such adjustment.

            Registration Statement on Form S-3

Ladies and Gentlemen:

      You have requested our opinion in connection with your Registration
Statement on Form S-3, filed under the Securities Act of 1933, as amended, with
the Securities and Exchange Commission (the "Registration Statement"), in
respect of a resale offering of an aggregate of 1,090,000 authorized and issued
shares of the Common Stock, par value $.10 per share (the "Common Stock"), of
Ultralife Batteries, Inc. (the "Corporation"), which may be sold by certain
stockholders of the Corporation and 109,000 shares of Common Stock to be issued
upon the exercise of certain warrants to purchase the Corporation's Common
Stock.

      We have examined the following corporate records and proceedings of the
Corporation in connection with the preparation of this opinion: its Certificate
of Incorporation; its By-laws as currently in force and effect; its Minute
Books, containing minutes and records of other proceedings of its stockholders
and its Board of Directors, from the date of incorporation to the date hereof;
the Registration Statement; applicable provisions of the laws of the State of
Delaware; and such other documents and matters as we have deemed necessary.

      In rendering this opinion, we have made such examination of laws as we
have deemed relevant for the purposes hereof. As to various questions of fact
material to this opinion, we have relied upon representations and/or
certificates of officers of the Corporation, certificates and documents issued
by public officials and authorities, and information received from searchers of
public records.

      Based upon and in reliance on the foregoing, we are of the opinion that:

            1. The Corporation has been duly incorporated and is validly
      existing under the laws of the State of Delaware.

            2. The Corporation had the authority to issue an aggregate of
      1,090,000 shares of Common Stock and to authorize the issuance of an
      aggregate 109,000 shares of Common Stock upon exercise of the warrants.

            3. The 1,090,000 shares of Common Stock issued by the Corporation
      and registered pursuant to the Registration Statement were legally and
      validly issued, and are fully paid and non-assessable, and the warrants
      have been legally and validly issued, and upon issuance in accordance with
      the terms and provisions of the warrants, the shares of Common Stock
      issued upon exercise of the warrants will be legally and validly issued,
      and will be fully paid and non-assessable.

      We hereby consent to be named in the Registration Statement as attorneys
passing upon legal matters in connection with the registration of the 1,199,000
shares of Common Stock covered thereby, and we hereby consent to the filing of
this opinion as Exhibit 5 to the Registration Statement.

                                          Very truly yours,

                                          /s/ HARTER, SECREST & EMERY LLP
