                                  COMMON STOCK

                              --------------------


      This Prospectus  relates to the public offering of 1,199,000 shares of our
Common Stock, par value $.10 per share. Of the total 1,199,000 shares, 1,090,000
of such shares are being registered for the accounts of the selling stockholders
identified  in  Table  A in  the  section  titled  "Selling  Stockholders".  The
remaining 109,000 of such shares are being registered for the accounts of future
stockholders  who will  receive  their  shares upon the exercise of the warrants
held by those  parties  identified  in Table B in the  Section  titled  "Selling
Stockholders".  This offering will not be underwritten. All 1,199,000 shares may
be offered by certain of our stockholders 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. Of the shares being registered,
1,090,000  of such  shares  were  originally  issued  in a  private  transaction
pursuant to that certain  Share  Purchase  Agreement  dated July 19, 2001 by and
among the Company and  subscribers  identified in Table A in the section of this
Prospectus  entitled  "Selling  Stockholders".  The issuance of these shares was
exempt from  registration  under Section 4(2) of the  Securities Act of 1933, as
amended, and Regulation D. We are registering the shares pursuant to Section 7.1
of the Share  Purchase  Agreement.  The remaining  109,000 shares are subject to
future  issuance upon the exercise of warrants  granted to our placement  agent,
H.C.  Wainwright  & Co.,  Inc. and several of its  affiliates,  pursuant to that
certain  Warrant  Agreement  dated as of July 20, 2001 by and among the Company,
H.C.  Wainwright  and  its  affiliates.  We  are  registering  these  shares  in
accordance with the provisions of that Warrant Agreement.


      The shares we are registering  may be offered 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. The shares
may be offered at fixed prices that 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 act as agents or to whom they sell as principals,  or both.
This  compensation  might be in excess of  customary  commissions.  For  further
information, see the section entitled "Plan of Distribution" below.


      We will not receive  any of the  proceeds  from the sale of these  shares.
However,  to the  extent  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  certain  expenses  in
connection  with the  registration  of the shares being  offered and sold by the
selling  stockholders  (including  those holding stock as a result of the future
exercise of the  warrants).  Our Common  Stock is quoted on the Nasdaq  National
Market under the symbol  "ULBI." On October 19,  2001,  the last  reported  sale
price for the Common Stock was $4.93.

                               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 September 30, 2001,
we had approximately 499 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.

(1)   This Registration  Statement shall also cover any additional shares of our
      Common Stock which  become  issuable in  connection  with the Common Stock
      registered for sale hereby by reason of any stock  dividend,  stock split,
      recapitalization or other similar transaction effected without the receipt
      of  consideration  which  results  in an  increase  in the  number  of our
      outstanding shares of Common Stock.

      and 231,980 shares out of 700,000 shares owned by Ultralife Taiwan,  Inc.,
      a Taiwanese venture of which the Company owns approximately 33%.


      The  following  Table B sets forth the number of shares of Common Stock to
be owned upon exercise of the warrants issued to H.C. Wainwright & Co., Inc. and
several of its affiliates as partial  compensation for its services as placement
agent  in  connection  with  our  private  placement.  The  warrantholders  have
confirmed  to us  that  none  had  agreements  or  understandings,  directly  or
indirectly,  with any  person to  distribute  the  Common  Stock  issuable  upon
exercise of the  warrants.  Because the  warrantholders  or  subsequent  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 warrantholders or subsequent  selling  stockholders after completion
of this offering. The shares offered by this Prospectus may be offered from time
to  time  by the  warrant  holders  or  subsequent  selling  stockholders  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.

      of  consideration  which  results  in an  increase  in the  number  of our

                              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).

                                  LEGAL MATTERS

      The validity of the  securities  offered hereby will be passed upon for us
by Harter, Secrest & Emery LLP, Rochester, New York.

ITEM 15. 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.

ITEM 17. 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


                                      II-2


offered  therein,  and the  offering  of such  securities  at that time shall be
deemed to be the initial bona fide offering thereof.

      (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  24th day of
October, 2001.
