                          Common Stock, $0.01 par value

         This prospectus of Ezenia! Inc., a Delaware corporation, relates to the
public offering of up to 400,000 shares of Ezenia!'s common stock, par value
$0.01 per share, by a certain stockholder of Ezenia!. More information is

shares by the selling stockholder. Ezenia!'s common stock is listed on the
Nasdaq National Market under the symbol "EZEN". On August 1, 2001, the closing
sale price of the common stock, as reported on the Nasdaq National Market, was
$0.28 per share.

         The selling stockholder may sell the shares in public or private
transactions, on or off the National Market System of the Nasdaq Stock Market,
at prevailing market prices, or at privately negotiated prices. The selling
stockholder may sell the shares directly to purchasers or through brokers or
dealers. Brokers or dealers may receive compensation in the form of discounts,
concessions or commissions from the selling stockholder. More information is
provided in the section titled "Plan of Distribution."

          INVESTING IN THE COMMON STOCK INVOLVES A HIGH DEGREE OF RISK.

                           FORWARD-LOOKING STATEMENTS

         This prospectus includes forward-looking statements within the meaning
of Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934. Words such as "expect," "anticipate," "intend," "plan,"
"believe," "estimate," "likely," "will," "should" and variations of such words
and similar expressions are intended to identify such forward-looking
statements.

         These forward-looking statements are not guarantees of future
performance and are subject to risks, uncertainties and assumptions. The actual
results of Ezenia! could differ materially from those anticipated in the
forward-looking statements due to a number of factors, including those set forth
under "Risk Factors," in information incorporated by reference and elsewhere in
this prospectus. The factors set forth under "Risk Factors" and other cautionary
statements made in this prospectus should be read and understood as being
applicable to all related forward-looking statements wherever they appear in
this prospectus.

         The forward-looking statements contained in this prospectus represent
our judgment as of the date of this prospectus. Ezenia! cautions readers not to
place undue reliance on such statements. We undertake no obligation to update
publicly any forward-looking statements for any reason, even if new information
becomes available or other events occur in the future.

                                  RISK FACTORS

         BEFORE YOU INVEST IN OUR COMMON STOCK, YOU SHOULD BE AWARE THAT THERE
ARE VARIOUS RISKS, INCLUDING THOSE DESCRIBED BELOW, THAT COULD HAVE A MATERIAL
ADVERSE EFFECT ON OUR BUSINESS, INCLUDING OUR OPERATING RESULTS AND FINANCIAL
CONDITION. THE RISK FACTORS LISTED IN THIS SECTION, AS WELL AS ANY CAUTIONARY
LANGUAGE IN THIS PROSPECTUS, PROVIDE EXAMPLES OF RISKS, UNCERTAINTIES AND EVENTS
THAT MAY CAUSE OUR ACTUAL RESULTS TO DIFFER MATERIALLY FROM THE EXPECTATIONS WE
DESCRIBE IN OUR FORWARD-LOOKING STATEMENTS. YOU SHOULD CAREFULLY CONSIDER THESE
RISK FACTORS, TOGETHER WITH ALL OF THE OTHER INFORMATION INCLUDED IN OR
INCORPORATED BY REFERENCE INTO THIS PROSPECTUS, BEFORE YOU DECIDE WHETHER TO
PURCHASE SHARES OF OUR COMMON STOCK.

WE HAVE NEVER ACHIEVED PROFITABILITY AND WE MAY BECOME UNABLE TO FUND OPERATIONS
IN THE NEAR FUTURE

         We have never achieved profitability and, since inception, have
incurred significant net operating losses. At July 1, 2001, we had an
accumulated deficit of approximately ($26,339). We expect to continue to
incur losses for the foreseeable future. Our ability to continue as a going
concern is dependent upon our ability to raise additional capital or to improve
operating margins considerably. There is little likelihood of securing
additional capital on reasonable terms, if at all, in the near future.
Accordingly, we recently implemented a restructuring and cost reduction plan to
align company resources and expenses with our current revenue forecasts. This
plan involved a reduction in workforce of approximately one hundred employees,
including engineering, marketing and manufacturing employees in Burlington,
Massachusetts and salespeople in North America and Europe. In addition, our
restructuring and cost reduction plan calls for the Company to close down our
Burlington, Massachusetts facility and move our office headquarters to a
smaller, more cost efficient facility. There can be no assurance that any
actions implemented by the Company will reduce expenses or increase revenue to
the extent desired or that any reduction in expenses or increase in revenue will
materially extend the Company's ability to continue operations.

OUR COMMON STOCK MAY BE DELISTED FROM THE NASDAQ NATIONAL MARKET

         The Company's common stock is presently listed on the Nasdaq National
Market under the symbol EZEN. All companies listed on Nasdaq are required to
comply with certain continued listing standards, including maintaining a minimum
bid price for its common stock of at least $1.00. As of June 29, 2001, the
Company did not meet this standard since its common stock had not traded at a
minimum bid price of at least $1.00 over the previous 30 consecutive trading
days. Pursuant to Nasdaq rules, the Company has until September 27, 2001 to meet
the required $1.00 minimum bid price for its common stock for at least 10
consecutive trading days. If the Company does not meet such standard by
September 27, 2001, or if it is determined that, notwithstanding its meeting
such standard, the Company is otherwise not in compliance with Nasdaq rules, the
Company's common stock will be delisted from Nasdaq unless the Company
successfully appeals the delisting determination. There can be no assurance that
the Company's common stock will meet the required $1.00 minimum bid price at any
time in the future or that any appeal by the Company of a delisting
determination would be successful. There can therefore be no assurance that the
Company's common stock will continue to be listed on Nasdaq in the future. In
the event that the Company's common stock is delisted from Nasdaq, the market
value and liquidity of the Company's common stock could be materially adversely
affected.

WE HAVE RECENTLY REVISED OUR BUSINESS STRATEGY

         With the acquisition of InfoWorkSpace, a business area of General
Dynamics Government Systems Corporation, in March 2001, we have continued to
shift our focus away from traditional ISDN-based videoconferencing products to
IP and Internet based videoconferencing and real-time collaboration products.
Sales of real-time collaboration products account for an increasing portion of
the Company's revenue. The Company's success depends, to a significant extent,
on the acceptance and the rate of adoption of collaboration products, in general
and its products in particular. There is inadequate experience to predict
whether real-time collaboration products will ultimately be accepted by the
market. There can be no assurance that any of the markets for the Company's
products will develop to the extent, in the manner, or at the rate anticipated
by the Company. In addition, future prices the Company is able to obtain for its
products may decrease as a result of new product introductions by others, price
competition, technological change or other factors.

                                       3


WE DEPEND ON A SMALL NUMBER OF MAJOR CUSTOMERS

         Historically, sales to a relatively small number of customers have
accounted for a significant portion of our revenue. The Company believes that
its dependence on a similarly few number of customers will continue during 2001.
This concentration of customers may cause revenues and operating results to
fluctuate from quarter to quarter based on major customers' requirements and the
timing of their orders. Our agreements with our customers generally do not
include minimum purchase commitments or exclusivity arrangements. Our operating
results could be materially and adversely affected if any present or future
major customer were to choose to reduce its level of orders, were to change to
another vendor for purchases of a similar product, were to combine their
operations with another organization that had an established relationship with
another vendor for purchases of a similar product, were to experience financial,
operational or other difficulties or were to delay paying or fail to pay amounts
due. Early in 2000, PictureTel Corporation, our largest customer in 2000,
reported that it is experiencing financial difficulties and is presently in the
process of being acquired.

OUR STOCK PRICE HAS BEEN EXTREMELY VOLATILE AND MAY CONTINUE TO BE SO IN THE
FUTURE

         Our shares have traded at prices between $0.37 and $5.375 per share in
the past twelve months. Additionally, the market for shares in
technology-related companies is subject to extreme price and volume
fluctuations. Market reaction to information relating to our company, as well as
broad fluctuations in market prices of shares in similarly situated companies,
may materially and adversely affect the price of our common stock. The price of
our shares may continue to be volatile in the future, and may be affected by a
number of factors, including:

         o  actual or perceived likelihood of our inability to continue funding
            operations

         o  actual or anticipated fluctuations in our operating results

         o  changes in investors' and securities analysts' expectations as to
            our future financial performance or changes in financial estimates
            of securities analysts

         o  announcement of new products or product enhancements by us or our
            competitors

         o  technological innovations by us or our competitors

         o  the operating and stock price performance of comparable companies

INCREASED COMPETITION MAY RESULT IN DECREASED DEMAND FOR OUR PRODUCTS AND
SERVICES

         The market for multimedia collaboration products is highly competitive
and is subject to rapid technological change. Additional competition could
adversely affect the Company's sales and profitability, through price reductions
and loss of market share. Many of the Company's current and potential
competitors have substantially greater financial, technical, and sales and
marketing resources than the Company.

         The principal competitive factors in the market for multimedia
collaboration are, and should continue to be, breadth of capabilities,
demonstrated interoperability, price, performance, network management
capabilities, reliability and customer support. While the Company believes it
presently competes favorably in all of these areas, there can be no assurance
that it will continue to do so.

         The Company currently competes, or expects to compete, directly or
indirectly with the real-time collaboration and video conferencing companies.

OUR OPERATING RESULTS MAY VARY FROM QUARTER TO QUARTER

         Our operating results are likely to vary significantly from quarter to
quarter as a result of several factors, including:

                                       4


         o  the timing of new product announcements and introductions by us and
            our major customers and competitors

         o  market acceptance of new or enhanced versions of our products

         o  changes in the product mix of revenue

         o  price reductions for our products

         o  the gain or loss of significant customers

         o  increased research and development expenses associated with new
            product introductions

         o  seasonality and general economic conditions

         New customers orders have generally been characterized by lengthy sales
cycles, making it difficult to predict the quarter in which sales will occur.
Also, ordering patterns have resulted in the Company recognizing a substantial
portion of its revenue in a given quarter from sales booked and shipped in the
last weeks of that quarter. These and other factors can materially adversely
affect the Company's business and operating results for one quarter or a series
of quarters, and are difficult to forecast.

OUR INDUSTRY IS CHARACTERIZED BY RAPID TECHNOLOGICAL CHANGE

         The market for our products is characterized by rapidly changing
technology, evolving industry standards, emerging network architectures and
frequent new product introductions. The adoption rate of new technologies and
products may adversely impact near-term growth of the conferencing market as
users evaluate the alternatives. We have invested, and for 2001 plan to continue
to invest, in software development and products incorporating certain of these
new technologies. Many other companies are also developing products
incorporating these new technologies that are competitive with Ezenia!'s current
and future offerings. Ezenia!'s success will depend, in part, upon the
following:

         o  our ability through continued investments to maintain technological
            leadership

         o  our ability to enhance and expand our existing product offerings

         o  our ability to select and develop in a timely manner new products
            that achieve market acceptance

If we are unable, for technical or other reasons, to develop and introduce new
services or enhancements of existing services in a timely manner in response to
changing market conditions or customer requirements, or if new services do not
achieve market acceptance, our business, financial condition and results of
operations could be materially and adversely affected.

WE DEPEND ON OUR KEY PERSONNEL TO IMPLEMENT OUR BUSINESS STRATEGY

         Our success depends, to a significant degree, upon the continuing
contributions of our key management, sales, marketing and research and
development personnel, many of whom would be difficult to replace. We do not
have employment contracts with most of our key personnel. The Company believes
that its future success will depend in large part upon its ability to attract
and retain such key employees

WE MAY NOT BE ABLE TO PROTECT OUR INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS

         Ezenia!'s success and ability to compete, depends, to a large extent,
on our ability to protect our proprietary technology. In addition to our patents
and patent applications relating to our products, we rely primarily on a
combination of contractual rights, trade secrets and copyrights to protect our
intellectual property rights.

                                       5


         Legal standards relating to the protection of intellectual property
rights in Internet-related industries are uncertain and still evolving. As a
result, the future viability or value of our intellectual property rights, as
well as those of other companies that conduct business over the Internet, is
unknown. Despite our efforts to protect our proprietary rights, unauthorized
parties may attempt to copy aspects of our technology or obtain and use
information that we regard as proprietary. Policing unauthorized use of our
proprietary rights is difficult. In addition, litigation may be necessary in the
future to enforce our intellectual property rights, to protect our trade secrets
or trademarks or to determine the validity and scope of the proprietary rights
of others. Litigation might result in substantial costs and diversion of
resources and management attention. Any infringement or misappropriation of our
proprietary rights and the related costs of enforcing those rights could have a
material adverse effect on our business, financial condition and results of
operations.

WE MAY INFRINGE UPON OTHER PARTIES' PROPRIETARY RIGHTS

         Our business activities may infringe upon the proprietary rights of
others and other parties may assert infringement claims against us. Moreover,
from time to time, third parties may allege infringement by us or our strategic
partners on their trademarks, service marks and other intellectual property
rights. Such claims and any resultant litigation could subject us to significant
liability for damages, might result in invalidation of our proprietary rights
and, even if not meritorious, could result in substantial costs and diversion of
resources and management attention and have a material adverse effect on our

PROVISIONS OF OUR GOVERNING DOCUMENTS AND DELAWARE LAW COULD DISCOURAGE
ACQUISITION PROPOSALS OR DELAY A CHANGE IN CONTROL OF EZENIA!

         Our certificate of incorporation and by-laws contain anti-takeover
provisions, including those listed below, that could make it more difficult for
a third party to acquire control of us, even if that change in control would be
beneficial to shareholders:

         o  our board of directors has the authority to issue common stock and
            preferred stock and to determine the price, rights and preferences
            of any new series of preferred stock without shareholder approval

         o  our board of directors is divided into three classes, each serving
            three-year terms

         o  supermajority voting is required to amend key provisions of our
            certificate of incorporation and by-laws

         o  there are limitations on who can call special meetings of
            shareholders

         o  shareholders may not take action by written consent

         o  advance notice is required for nominations of directors and for
            shareholder proposals

         In addition, provisions of Delaware law and our stock option plans may
also discourage, delay or prevent a change of control of Ezenia! or unsolicited
acquisition proposals.

                               SELLING STOCKHOLDER

         On March 27, 2001, General Dynamics Government Systems Corporation
acquired 400,000 shares of Ezenia!'s common stock in a transaction exempt from
the registration requirements of the Securities Act of 1933, in connection with
an asset purchase agreement, dated as of December 28, 2000. Pursuant to the
asset purchase agreement, Ezenia! purchased all of the operating assets and
intellectual property used by the Electronic Systems division of General
Dynamics Government Systems Corporation in the conduct of its InfoWorkSpace
product and technology business in exchange for $17,000,000 in cash and 400,000
shares of Ezenia!'s common stock.

         Pursuant to the asset purchase agreement, Ezenia! agreed to file with
the Securities and Exchange Commission a registration statement, of which this
prospectus is a part, with respect to the resale of the 400,000 shares issued to
General Dynamics Government Systems Corporation. Ezenia! has committed to keep
the registration statement effective until the earlier of (i) March 27, 2003 or
(ii) such times as all of the shares have been resold.

         Our registration of the shares does not necessarily mean that General
Dynamics Government Systems Corporation will sell all or any of the shares. The
information provided in the table below with respect to General Dynamics
Government Systems Corporation has been obtained from General Dynamics
Government Systems Corporation. General Dynamics Government Systems Corporation
has not had any position, office or other material relationship with Ezenia! or
any of its affiliates. Because General Dynamics Government Systems Corporation
may sell all or some or none of the shares, only an estimate (assuming the sale
of all of the shares) can be given as to the number of shares of common stock
that will be owned by General Dynamics Government Systems Corporation after this
offering.

         As of July 31, 2001, there were 13,741,880 shares of Ezenia!'s common
stock issued and outstanding.

                              PLAN OF DISTRIBUTION

         The shares may be sold from time to time by General Dynamics Government
Systems Corporation or its donees, pledgees, transferees and other successors in
interest in one or more transactions at fixed prices, at market prices at the
time of sale, at varying prices determined at the time of sale or at negotiated
prices. The shares may be sold in one or more of the following transactions:

         -- on any national securities exchange or quotation service on which
            the common stock may be listed or quoted at the time of sale,
            including the Nasdaq National Stock Market,
         -- in the over-the-counter market,
         -- in private transactions,
         -- through options, or
         -- a combination of any of the above transactions.

         Ezenia! reserves the right to terminate the registration statement of
which this prospectus forms a part at any time after March 17, 2003.

         At the time a particular offering of the shares is made, a supplement
to this prospectus, if required, will be distributed which will set forth the
aggregate number and type of shares being offered and the terms of the offering,
including the name or names of any underwriters, brokers/dealers or agents, any
discounts, commissions and other terms constituting compensation from General
Dynamics Government Systems Corporation and any discounts, commissions or
concessions allowed or reallowed to be paid to broker/dealers.

         The shares may be sold from time to time directly by General Dynamics
Government Systems Corporation. Alternatively, General Dynamics Government
Systems Corporation may from time to time sell or distribute the shares to or
through broker/dealers or agents. General Dynamics Government Systems
Corporation and any broker/dealers or agents that participate in the
distribution of the shares may be deemed to be "underwriters" within the meaning
of the Securities Act of 1933. Any profits on the resale of the shares and any
compensation received by any broker/dealer or agent may be deemed to be
underwriting discounts and commissions under the Securities Act of 1933.

         To comply with the securities laws of certain jurisdictions, if
applicable, the shares must be offered or sold only through registered or
licensed brokers or dealers. In addition, in certain jurisdictions, the shares
may not be offered or sold unless they have been registered or qualified for
sale or an exemption is available and complied with.

         Under applicable rules and regulations under the Securities Exchange
Act of 1934, any person engaged in a distribution of the shares offered hereby
may not simultaneously engage in market-making activities with respect to our
common stock for a specified period prior to the start of the distribution. In
addition, General Dynamics Government Systems Corporation and any other person
participating in a distribution will be subject to the Securities Exchange Act
and the rules and regulations promulgated under the Securities Exchange Act,
including Regulation M, which may limit the timing of purchases and sales of the
shares by General Dynamics Government Systems Corporation or any such other
person. These factors may affect the marketability of the shares and the ability
of brokers or dealers to engage in market-making activities.

         We shall pay all expenses of this registration. These expenses include
the SEC's filing fees and any fees under state securities or "blue sky" laws.
General Dynamics Government Systems Corporation will pay all underwriting
discounts and selling commissions, if any.

ITEM 17. UNDERTAKINGS

         The undersigned registrant hereby undertakes:

                           (1) To file, during any period in which offers or
                  sales are being made pursuant to this registration statement,
                  a post-effective amendment to this registration statement to
                  include any material information with respect to the plan of
                  distribution not previously disclosed in this registration
                  statement or any material change to such information in this
                  registration statement;

                           (2) That, for the purpose of determining any
                  liability under the Securities Act of 1933, each such
                  post-effective amendment shall be deemed to be a new
                  registration statement relating to the securities offered
                  therein, and the offering of such securities at that time
                  shall be deemed to be the initial bona fide offering thereof.

                           (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 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.

         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 described in Item 15 above,
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 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 and will be governed by the final adjudication of such issue.
