in a broad range of applications and end markets.

Since our  founding  in 1981 as a  Delaware  corporation,  we have  consistently
designed  innovative  embedded  products  and  system  solutions  that  focus on
attributes  such  as  reduced   time-to-market   for  our  customers,   enhanced

adapting our products and services to a constantly  changing,  technology-driven
marketplace  through the course of several  business  cycles that have  occurred

Our annual operating  performance is subject to various risks and uncertainties.
The following  discussion  should be read in conjunction  with the  consolidated
financial  statements and related notes included in our Form 10-K dated December

include, among other factors, general business and economic conditions, rapid or
unexpected  changes in  technologies,  cancellation or delay of customer orders,
including  those  relating to the "design  wins",  as discussed in our Form 10-K
referenced above, unreliability of customer forecasts, changes in the product or
customer  mix of sales,  delays in new  product  development,  delays or lack of

                               Recent Developments

On January 23, 2004,  we acquired the business of Mapletree  Networks,  Inc., by
purchasing substantially all of that company's assets. Mapletree Networks, Inc.,
a leader in voice  processing  products,  using DSP  technology  for voice  over
Internet Protocol (VoIP), wireless and media processing applications, is located
in Norwood, Massachusetts. We now operate that acquired business as an operating
unit of the Company through our wholly-owned subsidiary.

On February 18, 2004,  we entered into an agreement to invest up to $3.0 million
in InSciTek  Microsystems,  Inc. in the form of an interest bearing  convertible
note.  InSciTek,  based in the Rochester,  New York area, is an emerging company
that has developed a highly integrated, IP-based communications server appliance
for small to mid-size businesses.

                           The Securities We May Offer

With this prospectus,  we may offer common stock,  and the selling  stockholders
named in this  prospectus  may sell shares of our common  stock.  The  aggregate
offering  price of securities  that we may offer with this  prospectus  will not
exceed  $75,000,000.  In  addition,  the  selling  stockholders  named  in  this
prospectus  may sell up to 1,000,000  shares of our common  stock.  See "Selling
Stockholders".  Each time we and/or the selling  stockholders  offer  securities
with this prospectus, we will provide offerees with a prospectus supplement that
will contain the specific terms of the securities  being offered.  The following
is a summary of the securities we and/or the selling stockholders may offer with
this prospectus.


Common Stock

We and the selling  stockholders may offer shares of our common stock, par value
$0.01 per share. In this prospectus,  we provide a general description of, among
other things, our dividend policy and the transfer and voting  restrictions that
apply to holders of our common stock.

                                  RISK FACTORS

You should carefully  consider the risks described below before investing in our
securities.  You  should  also  refer  to the  other  information  contained  or
incorporated by reference in this  prospectus and in any prospectus  supplement.
If any of the following risks occur, our business could be harmed.

If we do not respond adequately to technological changes, our competive position
will decline.

The market for our products is characterized by rapid  technological  change and
frequent introduction of products based on new technologies. As new products are
introduced,  the industry standards change.  Additionally,  the overall embedded
systems market, particularly the telecommunications industry, is volatile as the
effects of new technologies,  new standards,  new products and short life cycles
contribute   to  changes  in  the  market  and  the   performance   of  industry
participants.  Our future  revenue  will depend  upon our ability to  anticipate
technological changes and to develop and introduce enhanced products on a timely
basis that comply with new industry standards. New product introductions, or the
delays thereof,  could contribute to quarterly fluctuations in operating results
as orders for new products  commence and orders for existing  products  decline.
Moreover,  significant  delays  can occur  between a  product  introduction  and
commencement of volume production.  The inability to develop and manufacture new
products  in  a  timely  manner,  the  existence  of  reliability,   quality  or
availability  problems in our products or their component  parts, or the failure
to achieve  market  acceptance  for our products  would have a material  adverse
effect on our revenue and operating results. Further, in a poor economic climate
such as today, current technologies may become obsolete before being replaced by
new technologies.

We operate in an extremely  competitive  industry and our revenues and operating
results will suffer if we do not compete effectively.

The embedded systems market,  particularly the  telecommunications  industry, is
extremely competitive. We face a number of large and small competitors.  Many of
our principal  competitors  have  established  brand name recognition and market
positions and have substantially greater experience and financial resources than
us to deploy on promotion,  advertising,  research and product  development.  In
addition,  as we broaden our product  offerings,  we expect to face  competition
from new  competitors.  Companies in related  markets could offer  products with
functionality  similar or superior to that  offered by our  products.  Increased
competition could result in price reductions, reduced margins and loss of market
share,  all of which  would  materially  and  adversely  affect our  revenue and
operating  results.  Large  companies  have  recently  acquired  several  of our
competitors.  These  acquisitions are likely to permit our competition to devote
significantly  greater  resources  to  the  development  and  marketing  of  new
competitive products and the marketing of existing competitive products to their
larger installed  bases. We expect that competition will increase  substantially
as a result of these and other industry consolidations and alliances, as well as
the emergence of new  competitors.  We cannot  guarantee that we will be able to
compete  successfully  with our existing or new competitors or that  competitive
pressures faced by us will not have a material adverse effect on our revenue and
operating results.

We are dependent on a number of key  customers,  the loss of any of which  would
harm our revenues and operating results.

We cannot assure that our principal customers will continue to purchase products
from us at current  levels.  Customers  typically  do not enter  into  long-term
volume  purchase  contracts with us  and customers have certain rights to extend
or delay  the  shipment  of their  orders.  The loss of one or more of our major
customers,  the  reduction,  delay  or  cancellation  of  orders,  or a delay in
shipment of our products to such customers, would have a material adverse effect
on our revenue and operating results.

Achieving  "design  wins" is an important  indicator of success in our industry;
however,  many factors  beyond our control  influence  whether we achieve design
wins that result in meaningful revenue generation.

A design win occurs when a customer or prospective customer notifies us that our
product has been selected to be integrated with their product. Ordinarily, there
are several steps between the time of the design win and when customers initiate
production shipments. Typically, design wins reach production volumes at varying
rates,  if they reach  production at all.  Historically,  this gestation  period
prior to volume  orders  has been  twelve to  eighteen  months or more after the
design win occurs.  A variety of risks such as schedule  delays,  cancellations,
and changes in customer  markets and economic  conditions can adversely affect a
design win before  production  is reached or during  deployment.  Traditionally,
design wins have been an important  metric for management and industry  analysts
to judge our product acceptance in its marketplace.  Unfortunately,  during weak
economic  periods,  fewer customers do new design activity and a smaller numbers
of these design wins move into production.

Our  annual  and  quarterly  results  can  fluctuate  greatly,  which can have a
disproportionate effect on the price of our commnon stock.

Our future annual and quarterly  operating  results can fluctuate  significantly
depending on factors such as the timing and shipment of significant  orders, new
product  introductions by us and our competitors,  market  acceptance of new and
enhanced  versions of our  products,  changes in pricing  policies by us and our
competitors,  the mix of  distribution  channels  through which our products are
sold,  inability  to  obtain  sufficient  supplies  of  sole or  limited  source
components for our products,  and seasonal and general economic conditions.  Our
expense levels are based,  in part, on our  expectations  as to future  revenue.
Since a substantial  portion of our revenue in each quarter  results from orders
placed  within the quarter and often shipped in the final weeks of that quarter,
revenue   levels  are  difficult  to  predict.   If  revenue  levels  are  below
expectations,  revenue and  operating  results will be adversely  affected.  Net
income would be  disproportionately  affected by a reduction in revenue  because
only a small portion of our net expenses varies with our revenue.

We depend on a  limited  number of  third-party  suppliers  to  provide  us with
important  components for our products.  If we were unable to obtain  components
from these suppliers, our revenue and operating results would suffer.

Certain components used in our products are currently  available to us from only
one or a  limited  number of  sources.  There can be no  assurance  that  future
supplies will be adequate for our needs or will be available on prices and terms
acceptable   to  us.  Our   inability   in  the  future  to  obtain   sufficient
limited-source  components,  or to develop alternative sources,  could result in
delays in product  introduction  or shipments,  and increased  component  prices
could negatively affect our gross margins, either of which would have a material
adverse effect on our revenue and operating results.

Potential limitations in our manufacturing arrangements could impair our ability
to meet our customers' expectations.

In order to avoid relying on outside contract manufacturers,  we manufacture our
network  access,  switch  and  signaling  products  at our  Rochester,  New York
facility.  The Company's  computing and platform products have been manufactured
at contract manufacturers.  We do not have significant alternative manufacturing
capabilities,  either  internally  or through  third  parties,  to  perform  our
manufacturing   functions.   Even  if  we  were  able  to  identify  alternative
third-party  contract  manufacturers,  we cannot assume that we would be able to
retain their services on terms and conditions  acceptable to us. In the event of
an  interruption  in production,  we would not be able to deliver  products on a
timely  basis,  which  would have a material  adverse  effect on our revenue and
operating results.  Although we currently have business interruption  insurance,
we cannot assure that such insurance would adequately cover our lost business as
a result of such an interruption.

If we do not adequately protect our proprietary technology, or if we infringe on
the intellectual  property rights of others,  our revenues and operating results
would suffer.

Our success depends upon our proprietary  technologies.  To date, we have relied
principally  upon  trademark,  copyright  and trade  secret  laws to protect our
proprietary  technologies.  We generally enter into  confidentiality  or license
agreements with our customers,  distributors  and potential  customers and limit
access  to, and distribution of, the  source  code  to our  software  and  other
proprietary  information.  Our  employees are subject to our  employment  policy
regarding  confidentiality.  We cannot assure that the steps taken by us in this
regard will be adequate to prevent  misappropriation  of our  technologies or to
provide an effective remedy in the event of a misappropriation by others.

Although we believe that our products do not infringe on the proprietary  rights
of  third  parties,  we  cannot  assure  that  infringement  claims  will not be
asserted, resulting in costly litigation in which we may not ultimately prevail.
Adverse  determinations  in such  litigation  could  result  in the  loss of our
proprietary rights,  subject us to significant  liabilities,  require us to seek
licenses  from third  parties or prevent us from  manufacturing  or selling  our
products, any of which would have a material  adverse  effect on our revenue and
operating results.

Because of the existence of a large number of patents in the computer networking
industry  and the rapid  rate of new  patents  granted or new  standards  or new
technology developed, we may have to enter into technology licenses from others.
We do not know whether these third party  technology  licenses will be available
to us on commercially reasonable terms. The loss of, or inability to obtain, any
of these technology licenses could result in delays or reductions in our product
shipments.  Any such  delays or  reductions  in  product shipments  would have a
material adverse effect on our revenue and operating results.

We are  dependent  upon a number of key  personnel.  The loss of these people or
delays in replacing them could harm our operating results.

Our success  depends on the continued  contributions  of our personnel,  many of
whom  would  be  difficult  to  replace.   Through  mid-2001,   competition  for
engineering   personnel  in  our  marketplace   was  intense.   Since  mid-2001,
engineering personnel seem to be more readily available.  Although our employees
are subject to our employment policy regarding  confidentiality and ownership of
inventions,  employees are  generally  not subject to  employment  agreements or
non-competition  covenants.  Changes in  personnel  could  adversely  affect our
operating results.

Delays in purchasing and implementing an  enterprise-wide  software system could
harm our operating results.

As a continuing effort to improve the flow of management information and control
of  our  operations,   we  intend  to  purchase,   install,   and  implement  an
enterprise-wide  software  system by the end of 2004.  We are  currently  in the
process of evaluating our requirements and available enterprise-wide systems. We
are examining the hardware,  software,  consulting,  and implementation costs of
available  systems  as well as the  internal  time and  resources  required  for
implementation.  Our  current  estimates  of the time  and  costs  necessary  to
implement a system are based upon the facts and information available today. New
developments may occur that could affect our estimates of the amount of time and
the  costs  necessary  to  implement  such a system.  Significant  delays in the
implementation   of  a  system,   interruption  in  business   activities  while
implementing a system,  or actual costs higher than  estimated,  could adversely
impact our operating results.

                                 USE OF PROCEEDS

We will use the net proceeds from the sale of securities  that we may offer with
this prospectus and any accompanying prospectus supplement for general corporate
purposes. General corporate purposes may include capital expenditures,  possible
acquisitions,  investments,  repurchase  of our  capital  stock  and  any  other
purposes that we may specify in any prospectus supplement. We may invest the net
proceeds  from this  offering  temporarily  until we use them for  their  stated
purpose.  We will not  receive any of the  proceeds  from the sale of our common
stock by selling stockholders.

                                 DIVIDEND POLICY

We have never  declared or paid any cash  dividends on our common stock or other
securities  and we do not  anticipate  paying cash  dividends in the future.  We
currently  intend to retain our  earnings,  if any,  for future  growth.  Future
dividends on our common stock or other securities,  if any, would be paid at the
discretion  of our board of directors in  accordance  with  applicable  laws and
would depend on, among other things,  our operations,  capital  requirements and
surplus,  general financial condition,  contractual  restrictions and such other
factors as our board of directors may deem relevant.

                              SELLING STOCKHOLDERS

All or any of the stockholders named below may from time to time offer and sell,
pursuant to this prospectus and the applicable prospectus  supplement,  up to an
aggregate of 1,000,000  shares of our common  stock.  The  following  table sets
forth,  as of March 10, 2004, the number of shares of our common stock that each
selling stockholder beneficially owned and the number of shares being registered
for sale by each selling  stockholder.  The  percentage  of  outstanding  shares
beneficially  owned before the offering is based on 12,712,000  shares of common
stock outstanding as of March 10, 2004. The term "selling stockholders," as used
in this  prospectus,  includes  the  holder  listed  below as well as his or her
transferees,  pledgees,  donees, heirs or other successors receiving shares from
the  holder  listed  below  after  the  date of  this  prospectus.  The  selling
stockholders  may sell,  transfer or  otherwise  dispose of some or all of their
shares  of our  common  stock  in  transactions  exempt  from  the  registration
requirements of the Securities Act.

The  selling  stockholders  may from  time to time  offer and sell any or all of
their  shares that are  registered  under this  prospectus.  Because the selling
stockholders  are not  obligated to sell their  shares,  and because the selling
stockholders  may also acquire  publicly  traded shares of our common stock,  we
cannot  estimate  how many shares of our common  stock the selling  stockholders
will own after this offering.  The percentage of our common stock to be owned by
each selling  stockholder  following the offering assumes the sale of all of the
registered  shares  of our  common  stock by that  selling  stockholder.  We may
update,  amend or  supplement  this  prospectus  from time to time to update the
disclosure in this section.  The actual amount, if any, of our common stock to
be offered by each selling stockholder and the amount and percentage of our
common stock to be owned by that selling stockholder following that offer will
be disclosed in the applicable prospectus supplement.

                                                                                                         of the Offering

                              PLAN OF DISTRIBUTION

We may sell shares of our common stock,  and the selling  stockholders  may sell
shares of our common stock, through underwriters,  agents,  dealers, or directly
to one or more purchasers.  We and the selling stockholders may distribute these
securities  from  time  to time in one or  more  transactions,  including  block
transactions  and  transactions  on The  Nasdaq  National  Market  or any  other
organized market where the securities may be traded.  The securities may be sold
at a fixed price or prices, at market prices prevailing at the times of sale, at
prices related to these prevailing  market prices or at negotiated  prices.  Any
such price may be changed from time to time.

We may permit the selling stockholders or their transferees,  pledgees,  donees,
heirs or other  successors to sell our common stock pursuant to this  prospectus
in conjunction  with an offering by us. The selling  stockholders  may only sell
pursuant to this prospectus  with our consent,  which consent may be withheld in
our sole discretion.  If selling  stockholders sell our common stock pursuant to
this prospectus,  a prospectus supplement will set forth information required by
the SEC  rules and  regulations  regarding  the  selling  stockholders.  Selling
stockholders  may also resell all or a portion of their  securities  in reliance
upon Rule 144 under the Securities  Act,  including  pursuant to written trading
plans  designed to comply with Rule 10b5-1 of the Exchange  Act,  provided  they
meet the criteria and conform to the requirements of Rule 144.

The prospectus supplement for the securities we and/or the selling stockholders
sell will describe that offering, including:

o  the identity  of any underwriters, dealers or agents who purchase securities,
   as required;

o  the amount of securities sold,  the public offering  price  and consideration
   paid, and the proceeds we  and/or the selling  stockholders will receive from
   that sale;

o  the place and time of delivery for the securities being sold;

o  whether or not the securities  will trade on any securities exchanges or  The
   Nasdaq National Market;

o  the amount of any compensation,  discounts or commissions  to be received  by
   underwriters,  dealers or agents,  any other items constituting underwriters'
   compensation,  and any discounts or concessions allowed or reallowed or  paid
   to dealers;

o  the terms of any indemnification  provisions,  including indemnification from
   liabilities under the federal securities laws; and

o  any other material terms of the distribution of securities.


Use of Underwriters, Agents and Dealers

We and/or  the  selling  stockholders  may offer the  securities  to the  public
through one or more underwriting  syndicates represented by one or more managing
underwriters,  or  through  one or more  underwriters  without a  syndicate.  If
underwriters  are used in the sale,  we and/or  the  selling  stockholders  will
execute an  underwriting  agreement  with  those  underwriters  relating  to the
securities that we and/or the selling  stockholders will offer and will name the
underwriters  and  describe  the  terms  of  the  transaction  in  a  prospectus
supplement.  The  securities  subject  to the  underwriting  agreement  will  be
acquired by the underwriters for their own account and may be resold by them, or
their  donees,  pledgees,  or  transferees,  from  time  to  time in one or more
transactions,  including  negotiated  transactions,  at a fixed public  offering
price or at varying prices determined at the time of sale. Subject to conditions
to be specified in the underwriting agreement, underwriters will be obligated to
purchase  all of these  securities  if any are  purchased  or will act on a best
efforts basis to solicit purchases for the period of their  appointment,  unless
we state otherwise in the prospectus supplement.

We and/or the selling stockholders may authorize  underwriters to solicit offers
by institutions to purchase the securities subject to the underwriting agreement
from us and/or the selling  stockholders  at the public offering price stated in
the prospectus supplement under delayed delivery contracts providing for payment
and  delivery  on a  specified  date in the  future.  If we and/or  the  selling
stockholders  sell securities under delayed delivery  contracts,  the prospectus
supplement  will state that as well as the  conditions  to which  these  delayed
delivery  contracts  will  be  subject  and the  commissions  payable  for  that
solicitation.

Underwriters may sell these securities to or through dealers.  Alternatively, we
and/or  the  selling  stockholders  may sell  the  securities  in this  offering
directly to one or more  dealers,  who would act as a principal  or  principals.
Dealers may then resell such  securities  to the public at varying  prices to be
determined by the dealers at the time of the resale.

We and/or the selling  stockholders  may also sell the  securities  offered with
this prospectus through other agents designated by us from time to time. We will
identify any agent involved in the offer or sale of these  securities who may be
deemed to be an underwriter under the federal  securities laws, and describe any
commissions or discounts payable by us and/or the selling  stockholders to these
agents,  in the  prospectus  supplement.  Any such agents will be  obligated  to
purchase  all of these  securities  if any are  purchased  or will act on a best
efforts basis to solicit purchases for the period of their  appointment,  unless
we state otherwise in the prospectus supplement.

In  connection  with the sale of the  securities  offered with this  prospectus,
underwriters,  dealers or agents may receive  compensation  from us, the selling
stockholders  or from  purchasers  of the  securities  for whom  they may act as
agents, in the form of discounts,  concessions or commissions.  These discounts,
concessions  or  commissions  may be  changed  from time to time.  Underwriters,
dealers and/or agents may engage in  transactions  with us, or perform  services
for us, in the ordinary  course of  business,  and may receive  compensation  in
connection  with those  arrangements.  In the event any  underwriter,  dealer or
agent  who is a  member  of  the  National  Association  of  Securities  Dealers
participates in a public offering of these securities, the maximum commission or
discount to be received  by any such NASD  member or  independent  broker-dealer
will not be greater than 8% of the offering  proceeds  from  securities  offered
with this prospectus.

Selling  stockholders,   underwriters,   dealers,   agents  or  purchasers  that
participate  in  the  distribution  of  the  securities  may  be  deemed  to  be
underwriters under the Securities Act. Broker-dealers or other persons acting on
behalf of parties that  participate  in the  distribution  of the securities may
also be deemed to be underwriters. Any discounts or commissions received by them
and any profit on the resale of the securities received by them may be deemed to
be underwriting discounts and commissions under the Securities Act.

Underwriters  and purchasers that are deemed  underwriters  under the Securities
Act may engage in transactions that stabilize,  maintain or otherwise affect the
price of the  securities,  including the entry of stabilizing  bids or syndicate
covering transactions or the imposition of penalty bids. Such purchasers will be
subject to the applicable  provisions of the Securities Act and Exchange Act and
the rules and  regulations  thereunder,  including  Rule 10b-5 and Regulation M.
Regulation M may restrict the ability of any person engaged in the  distribution
of the securities to engage in  market-making  activities  with respect to those
securities.  In addition, the anti-manipulation rules under the Exchange Act may
apply to sales of the securities in the market.  All of the foregoing may affect
the  marketability  of the securities and the ability of any person to engage in
market-making activities with respect to the securities.

Indemnification and Contribution

We and/or the selling stockholders may provide underwriters,  agents, dealers or
purchasers with indemnification against civil liabilities, including liabilities
under the  Securities  Act, or  contribution  with respect to payments  that the
underwriters,  agents,  dealers  or  purchasers  may make with  respect  to such
liabilities.

Because  selling  stockholders  may be deemed to be  "underwriters"  within  the
meaning  of  Section  2(11) of the  Securities  Act,  they may be subject to the
prospectus delivery requirements of the Securities Act.


                   DESCRIPTION OF SECURITIES TO BE REGISTERED

With this  prospectus,  we may offer shares of our common  stock.  The aggregate
offering  price of securities  that we may offer with this  prospectus  will not
exceed  $75,000,000.  In  addition,  the  selling  stockholders  named  in  this
prospectus may sell up to 1,000,000 shares of our common stock.

The following  description  of our capital  stock,  together with the additional
information  included in any applicable  prospectus  supplement,  summarizes the
material  terms and provisions of these types of securities but is not complete.
You should read our certificate of  incorporation,  as amended,  our bylaws,  as
amended, our rights plan (as described below) and the certificate of designation
relating to any particular  series of preferred stock before you purchase any of
our capital  stock or  securities  convertible  into shares of our capital stock
because  those  documents  and not this  description  set forth the terms of our
capital stock.

We will describe in a prospectus  supplement  the specific  terms of any capital
stock we may offer  pursuant to this  prospectus.  If  indicated in a prospectus
supplement,  the terms of such capital stock may differ from the terms described
below.

Authorized Capital Stock

Our  certificate  of  incorporation  provides  that we have  authority  to issue
50,000,000  shares of common  stock,  par  value  $0.01 per share and  1,000,000
shares of preferred stock, par value $0.01.

The  authorized  shares of common stock and  preferred  stock are  available for
issuance  without  further  action by our  stockholders,  unless  such action is
required  by  applicable  law or the rules of any stock  exchange  or  automated
quotation  system  on which our  securities  may be  listed  or  traded.  If the
approval of our  stockholders  is not so required,  our board of  directors  may
determine not to seek stockholder approval.

Common Stock

As of March 10, 2004, there were 12,712,000 shares of common stock  outstanding.
Common  stockholders are entitled to one vote for each share held on all matters
submitted to a vote of stockholders.  They do not have cumulative voting rights.
Common  stockholders  do  not  have  preemptive,  subscription,   redemption  or
conversion  rights.  The  outstanding  shares of common stock are fully paid and
nonassessable. The rights, preferences and privileges of common stockholders are
subject to the rights of the  stockholders  of any  series of  preferred  stock,
which we may  designate  and issue in the future.  We will describe the specific
terms of any common stock we may offer in a prospectus supplement.

Preferred Stock

Under our certificate of incorporation,  we have authorized  1,000,000 shares of
preferred  stock, par value $0.01 per share. At March 10, 2004, we had no shares
of  preferred  stock issued and  outstanding.  Our board of  directors,  without
further stockholder approval (except as may be required by applicable law or the
rules  of any  stock  exchange  or  automated  quotation  system  on  which  our
securities may be listed or traded) has the authority to issue from time to time
up to an aggregate of 1,000,000 shares of preferred stock in one or more series,
and  to  fix  or  alter   the   designations,   preferences,   rights   and  any
qualifications,  limitations  or  restrictions  of the  shares  of  each  series
thereof, including:

o  dividend rights;

o  dividend rates;

o  conversion rates;

o  voting rights;

o  terms of redemption (including sinking fund provisions);

o  redemption prices;

o  liquidation preferences; and

o  the  number of shares constituting  any series or designations of  such
   series.

In  addition,  our rights plan  provides for the issuance of shares of preferred
stock and common stock under the circumstances specified in the rights plan. See
"Certain Anti-Takeover  Provisions in Our Certificate of Incorporation,  Bylaws,
Rights Plan and  Delaware  General  Corporation  Law" below for a more  detailed
description of our rights plan.

Although  our board of  directors  has no intention at the present time of doing
so, it could  issue a series of  preferred  stock that could,  depending  on the
terms of such series,  impede the completion of a merger,  tender offer or other
takeover attempt.

Ranking

Each new series of  preferred  stock will rank with respect to each other series
of our preferred stock as specified in the  certificate of designation  relating
to that new series of preferred stock.

Dividends

Holders of each new series of  preferred  stock will be entitled to receive cash
dividends  or dividends  in kind,  if declared by our board of directors  out of
funds legally  available for dividends.  For each series of preferred  stock, we
will specify in the certificate of designation:

o  the dividend rates;

o  whether the rates will be fixed or variable or both;

o  the dates of distribution of the cash dividends; and

o  whether the dividends on any series of preferred stock will be  cumulative or
   non-cumulative.


Conversion and Exchange

The  certificate of designation for any new series of preferred stock will state
the terms and other  provisions,  if any,  on which  shares of the new series of
preferred stock are convertible  into shares of our common stock or exchangeable
for securities of a third party.

Redemption

We will specify in the certificate of designation relating to each new series of
preferred stock:

o  whether that new series will be redeemable at any  time, in whole or in part,
   at  our  option  or  at the option of the holder of the shares  of  preferred
   stock;

o  whether  that new  series  will be subject  to mandatory  redemption  under a
   sinking fund or on other terms; and

o  the redemption prices.

Liquidation Preference

Upon our voluntary or  involuntary  liquidation,  dissolution  or winding up, we
will  specify  how the  holders  of each new series of  preferred  stock will be
entitled to receive:

o  distributions upon liquidation  in  the amount provided in the  prospectus
   supplement relating to that series of preferred stock; and

o  any accrued and unpaid dividends.

These  payments  will be made to  holders of  preferred  stock out of our assets
available for  distribution to stockholders  before any  distribution is made on
any  securities  ranking  junior to the preferred  stock  regarding  liquidation
rights.

After payment of the full amount of the liquidation preference to which they are
entitled,  the  holders  of each  series  of  preferred  stock may or may not be
entitled to any further  participation  in any  distribution  of our assets,  as
provided in the  prospectus  supplement  relating  to that  series of  preferred
stock.

Voting Rights

The holders of shares of any series of preferred  stock will have voting  rights
as indicated in the  certificate of  designations  relating to that series or as
required by law.

Certain  Anti-Takeover  Provisions in Our Certificate of Incorporation,  Bylaws,
Rights Plan and Delaware General Corporation Law

The  following  is a  summary  of  certain  provisions  of  our  certificate  of
incorporation, bylaws, and rights plan and  Delaware law.  This summary does not
purport to be complete  and is  qualified  in its  entirety by  reference to our
certificate of  incorporation,  bylaws, and rights plan and the corporate law of
Delaware.

Certificate of Incorporation and Bylaws

Our certificate of  incorporation  includes several other provisions in addition
to our preferred  stock which may have the effect of  preventing  changes in our
management. These provisions may make an unfriendly tender offer, proxy contest,
merger or other change in control of us more  difficult.  These  provisions  are
intended  to  enhance  the   likelihood  of  continuity  and  stability  in  the
composition  of our board of  directors  and in the policies  formulated  by our
board of directors and to  discourage  certain  types of  transactions  that may
involve a change in control.  These  provisions  are also designed to reduce our
vulnerability  to unsolicited  acquisition  proposals and to discourage  certain
tactics that may be used in proxy fights. These provisions,  however, could have
the effect of  discouraging  others from making  tender offers for the shares of
our common stock and, as a consequence,  they also may inhibit  fluctuations  in
the market  price of the shares of our common  stock  which  could  result  from
actual or rumored takeover attempts.

Our bylaws  provide for our board of directors to be divided into three  classes
of directors  serving  staggered  three-year  terms. As a result,  approximately
one-third of our board of directors will be elected each year. Classification of
our board of directors  expands the time required to change the composition of a
majority  of  directors  and  may  tend to  discourage  a  takeover  bid for us.
Moreover,  under Delaware law, in the case of a corporation  having a classified
board of directors, the stockholders may remove a director only for cause. These
provisions, when coupled with provisions of our certificate of incorporation and
bylaws  authorizing  only our board of directors  to fill vacant  directorships,
will preclude our stockholders from removing  incumbent  directors without cause
or  simultaneously  gaining  control of our board of  directors  by filling  the
vacancies with their own nominees.

Our bylaws provide that special  meetings of stockholders  may be called only by
the chairman or by the  secretary or any  assistant  secretary at the request in
writing of a majority of our board of directors.  These  provisions  may make it
more  difficult  for  stockholders  to  take  action  opposed  by our  board  of
directors.

Our bylaws provide that stockholders  seeking to bring business before an annual
meeting of stockholders,  or to nominate candidates for election as directors at
an annual or a special  meeting of  stockholders,  must provide timely notice of
their intent in writing. To be timely, a stockholder's  notice must be delivered
to, or mailed and received at our principal  executive office (i) in the case of
an annual  meeting  that is called  for a date that is within 30 days  before or
after the  anniversary  date of the  immediately  preceding  annual  meeting  of
stockholders,  not  less  than 60 days  nor  more  than  90 days  prior  to such
anniversary  date, and, (ii) in the case of an annual meeting that is called for
a date that is not within 30 days  before or after the  anniversary  date of the
immediately preceding annual meeting not later than the close of business on the
tenth  day  following  the day on which  notice of the date of the  meeting  was
mailed or  public  disclosure  of the date of the  meeting  was made,  whichever
occurs first.  Our bylaws also specify  certain  requirement for a stockholders'
notice  to be in  proper  written  form.  These  provisions  may  preclude  some
stockholders  from  making  nominations  for  directors  at an annual or special
meeting or from bringing other matters before the stockholders at a meeting. Our
certificate of  incorporation  also  eliminates the right of stockholders to act
without a meeting.

Rights Plan

On October 27, 2000, our board of directors  adopted a rights plan. As a result,
we issued one purchase  right for each  outstanding  share of common stock.

Until the occurrence of certain events, the purchase rights are traded as a unit
with  common  stock.  Each of the  purchase  rights  will  separate  and entitle
stockholders  to buy preferred  and common stock upon the  occurrence of certain
events  generally  related to the change of control of our company as defined in
the rights. The purchase rights become exercisable ten days after either: (1) an
"Acquiring  Person"  acquires or commences a tender offer to acquire 15% or more
of our common stock, or (2) an "Adverse  Person" has acquired 10% or more of our
common  stock and our board of  directors  determines  this  person is likely to
cause  pressure  on us to  enter  into a  transaction  that  is not in our  best
long-term  interest.  All purchase rights not held by an Acquiring  Person or an
Adverse Person become rights to purchase from us one one-thousandth of one share
of preferred stock at an initial exercise price of $110 per purchase right. Each
purchase  right  entitles  the holder of that  purchase  right to  purchase  the
equivalent of $220 worth of our common stock for $110.

If after such an event our company merges,  consolidates or engages in a similar
transaction in which it does not survive, each holder has a "flip over" right to
buy discounted stock in the surviving  entity. We may redeem the purchase rights
for $.001 each.  The rights plan  expires on November 1, 2010 or can be modified
or terminated, at the option of our board of directors.

Section 203 of Delaware Law

We are  subject  to the  provisions  of  Section  203  of the  Delaware  General
Corporation Law. Section 203 prohibits publicly held Delaware  corporations from
engaging in a "business  combination"  with an  "interested  stockholder"  for a
period of three  years  after the date of the  transaction  in which the  person
became an interested stockholder, unless the business combination is approved in
a prescribed manner. A "business  combination" includes mergers, asset sales and
other   transactions   resulting  in  a  financial  benefit  to  the  interested
stockholder.  Generally,  an "interested  stockholder" is a person who, together
with  affiliates  and  associates,  owns or was,  within the three  year  period
immediately  prior to the date on which it is  sought to be  determined  whether
such  person  is an  interested  stockholder,  an  owner  of  15% or  more  of a
corporation's  voting stock. These provisions could have the effect of delaying,
deferring or preventing a change in control of our company or reducing the price
that certain  investors  might be willing to pay in the future for shares of our
common stock.

Transfer Agent and Registrar

The transfer agent,  registrar,  dividend  disbursing agent and redemption agent
for the shares of our common stock is American Stock Transfer & Trust Company.

                                  LEGAL MATTERS

Certain legal matters with respect to the securities  will be passed upon for us
by Harter, Secrest & Emery LLP, Rochester, New York.

Item 17.  Undertakings.

     (1)  The undersigned registrant hereby undertakes:

         (a) 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  reflected 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
          a 20  percent change in the maximum aggregate offering price set forth
          in  the  "Calculation  of  Registration  Fee"  table  in the effective
          Registration Statement;

                  (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 or any material change to  such information in
          the Registration Statement; provided, however, that paragraphs  (a)(i)
          and  (a) (ii)  do not apply if the information required to be included
          in  a  post-effective  amendment  by  those paragraphs is contained in
          periodic  reports filed with or furnished  to the  Commission  by  the
          registrant pursuant to Section 13 or Section 15(d)  of the  Securities
          Exchange Act  of 1934  that  are  incorporated  by  reference  in this
          Registration Statement.

         (b)  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.

         (c) 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.

     (2)  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 15(d) of  the Securities
Exchange Act of 1934 (and, where applicable,  each filing of an employee benefit
plan's annual report pursuant to 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.

     (3) 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 provisions described under Item 15, 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 Act  and is,  therefore,  unenforceable.  In the event that a  claim  for
indemnification  against such liabilities  (other than 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 Act  and will be governed by the final
adjudication of such issue.


                                   SIGNATURES

     Pursuant to the  requirements of the Securities Act of 1933, the Registrant
certifies  that it 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 Rochester, State of New York, on March 16, 2004.
