    This proxy statement and the proxy enclosed herewith were first mailed to

                               SUMMARY TERM SHEET

    This summary term sheet highlights selected information contained in this
proxy statement regarding the proposed sale of all of the patents, patent
applications and certain related assets relating to our multipoint
videoconferencing business, which together are referred to as the MCU patent
portfolio. The MCU patent portfolio relates to the traditional ISDN-based
videoconferencing products portion of our business, also known as the MCU
business. The MCU business is separate and distinct from the enterprise
collaboration business, which includes the InfoWorkSpace products and services,
that have become the central focus of our operations.

    This summary term sheet may not contain all of the information that is
important to you. To understand fully the proposed sale of the MCU patent
portfolio and for a more complete description of the legal terms of the proposed
sale, you should read carefully the entire proxy statement, including the asset
purchase agreement attached as Annex A.

                                            laws of the Kingdom of Norway and a wholly owned
                                            subsidiary of Tandberg ASA, is a leading global provider
                                            of videoconferencing solutions. Tandberg ASA is publicly

                                            symbol "TAA."

Description of the Transaction (page 12):   On August 1, 2002, Ezenia! and Tandberg entered into a

                                            a license to use the MCU patent portfolio for $1.25
                                            million, we borrowed $1.25 million from Tandberg and
                                            pledged the MCU patent portfolio as collateral, and we
                                            agreed, subject to shareholder approval, to sell the MCU
                                            patent portfolio to Tandberg for $3.75 million,
                                            consisting of $2.5 million in cash and forgiveness of
                                            the $1.25 million loan.

Asset Purchase Agreement (page 13):         GENERALLY. Under the terms of the asset purchase
                                            agreement, we propose to sell to Tandberg our MCU patent
                                            portfolio and certain related assets for $3.75 million,
                                            consisting of $2.5 million in cash and forgiveness of
                                            the $1.25 million that we owe Tandberg. Tandberg will
                                            not assume any of our liabilities, and we will not be

Use and Sufficiency of Sale Proceeds        The purpose and goal of our sale of the MCU patent
(page 16):                                  portfolio are to use the sale proceeds for general
                                            operating expenses to finance our enterprise
                                            collaboration business, including our InfoWorkSpace
                                            products, or to attempt to dispose of that business. In
                                            an effort to maximize the value of our common stock, we
                                            are assessing whether the capital requirements and
                                            competitive risks associated with developing our
                                            enterprise collaboration products outweigh the value
                                            that we might realize from a near-term sale of the
                                            business. We have engaged an investment banker to assist
                                            in investigating and assessing possible sale
                                            opportunities. However, we have no current plan,
                                            proposal or arrangement to sell our enterprise
                                            collaboration business.

Background of the Sale of the MCU Patent    Since the spring of 2001, we have been exploring
Portfolio (page 16):                        strategic alternatives in the face of significant
                                            internal restructuring, senior management turnover,
                                            declining financial results and competitive challenges.
                                            Since that time, we have also reported that our ability
                                            to continue as a going concern is dependent upon our
                                            ability to raise additional capital, increase revenue or
                                            substantially improve operating margins. We implemented
                                            restructuring and cost reduction plans in May 2001 and
                                            July 2002 to reduce operating costs. In light of our
                                            need of additional cash to continue operations, on
                                            August 1, 2002 we agreed to sell the MCU patent
                                            portfolio to Tandberg. This transaction offered more
                                            cash than any alternative available to us and only
                                            required us to transfer title to, but not our right to
                                            use, intellectual property relating to our MCU business,
                                            which has been of decreasing importance to us. In the
                                            course of reaching our decision to approve the sale of
                                            the MCU patent portfolio pursuant to the asset purchase
                                            agreement, our board of directors consulted with
                                            management as well as outside legal counsel.

Reasons for the Sale of the MCU Patent      Ezenia!'s board of directors considered numerous factors
Portfolio (page 19):                        relating to the benefits and risks associated with the
                                            asset purchase agreement and the sale of the MCU patent
                                            portfolio and unanimously determined that the sale of
                                            the MCU patent portfolio pursuant to the asset purchase
                                            agreement is expedient and in the best interest of
                                            Ezenia! and our shareholders.

Recommendation of the Board (page 20):      In light of our need of additional cash to continue
                                            operations and in recognition of the unavailability of
                                            more favorable financing alternatives, Ezenia!'s board
                                            of directors recommends that our shareholders vote for
                                            the approval of the sale of the MCU patent portfolio
                                            pursuant to the asset purchase agreement.

Accounting Treatment (page 20):             The proposed sale of the MCU patent portfolio is
                                            expected to be accounted for as a sale of certain
                                            assets, in accordance with accounting principles
                                            generally accepted in the United States. In the period
                                            in which the proposed sale of the MCU patent portfolio
                                            is consummated, we expect to recognize a gain in the
                                            amount of the difference between the sale price and the
                                            aggregate book value of the net assets sold.

Material Tax Consequences (page 21):        CONSEQUENCES FOR EZENIA!. We will recognize net taxable
                                            gains on the sale of the MCU patent portfolio equal to
                                            the excess of the amount realized on the sale over our
                                            aggregate adjusted basis in the assets sold. Although
                                            the gains will constitute capital gains, to the extent
                                            that we hold the MCU patent portfolio as capital assets,
                                            we expect that the gains will be offset by operating
                                            losses incurred during 2002 and/or by net operating loss
                                            carry-forwards from previous taxable years. The losses
                                            and/or loss carry-forwards so absorbed will not be
                                            available to offset income and gains that we may realize
                                            in the future.

                                            CONSEQUENCES FOR EZENIA!'S SHAREHOLDERS. The sale of the
                                            MCU patent portfolio will not, in and of itself, cause
                                            our shareholders to recognize any income for federal
                                            income tax purposes. The sale will generate "earnings
                                            and profits" for tax purposes. Though not anticipated,
                                            if we have positive earnings and profits for our 2002
                                            taxable year, then some or all of the distributions or
                                            deemed distributions made by us to shareholders during
                                            2002, if any, may be treated as taxable dividends.

                        QUESTIONS AND ANSWERS ABOUT THE
                           SPECIAL MEETING AND PROXY
                                   STATEMENT

WHO IS SOLICITING MY PROXY?

    Ezenia!'s board of directors is soliciting proxies from each of our
shareholders.

WHEN AND WHERE IS THE SPECIAL MEETING?

    This special meeting will be held on Monday, October 21, 2002 at
10:00 a.m., EST, at the offices of Bingham McCutchen LLP, 150 Federal Street,
Boston, Massachusetts 02110.

WHO MAY VOTE?

    Only shareholders of record of our common stock as of the close of business
on September 3, 2002 will be entitled to notice of, and to vote at, the special
meeting and any adjournments thereof. Each shareholder is entitled to one vote
per share.

HOW DO SHAREHOLDERS VOTE?

    Registered shareholders can vote their shares (1) by mailing their signed
proxy card, (2) via a toll-free telephone call from the U.S. or Canada, (3) via
the Internet or (4) in person at the special meeting. If a shareholder does not
intend to attend the special meeting, any written proxy or notice should be
returned to us, and any telephonic or Internet vote should be made, not later
than the close of business on Friday, October 18, 2002.

HOW DO PROXIES WORK?

    Giving your proxy means that you authorize us to vote your shares at the
special meeting in the manner you direct. If you sign, date and return the
enclosed proxy card but do not specify how to vote, the persons named as proxies
thereon will vote your shares FOR the sale of the MCU patent portfolio pursuant
to the asset purchase agreement and at their discretion with respect to any
other proposals that may properly come before the special meeting. We do not
know of any other matter that will be brought before the special meeting. The
persons named as proxies are employees of Ezenia!.

HOW MAY A PROXY BE REVOKED?

    You may revoke your proxy before it is voted (1) by delivering a later-dated
proxy, (2) by making an authorized telephone or Internet communication on a
later date in accordance with the instructions on the enclosed proxy card,
(3) by written notice of revocation to the secretary of Ezenia! at the address
for our principal executive offices set forth in this proxy statement or (4) by
voting in person at the special meeting.

WHAT HAPPENS IF I CHOOSE NOT TO SUBMIT A PROXY OR TO VOTE?

    If an Ezenia! shareholder does not submit a proxy or vote, it will have the
same effect as a vote against approval of the sale of the MCU patent portfolio.

HOW MANY VOTES ARE REQUIRED TO APPROVE THE SALE?

    The affirmative vote of a majority of the outstanding shares of our common
stock is required for the approval of the sale of the MCU patent portfolio. For
purposes of determining whether a proposal has received a majority vote,
abstentions will be included in the vote totals, with the result being that

                                       6
<Page>
an abstention will have the same effect as a negative vote. In instances where
brokers are prohibited from exercising discretionary authority for beneficial
holders who have not returned a proxy (so-called "broker non-votes"), those
shares will not be included in the vote totals and, therefore, will also have
the same effect as a negative vote. Shares that abstain or for which the
authority to vote is withheld on certain matters will, however, be treated as
present for quorum purposes on all matters.

WHO PAYS FOR THIS PROXY SOLICITATION?

    Ezenia! will bear the cost of solicitation of proxies relating to the
special meeting.

WHAT ARE THE SHAREHOLDERS BEING ASKED TO APPROVE?

    Each Ezenia! shareholder is being asked to vote in favor of the sale of our
MCU patent portfolio to Tandberg for $3.75 million, consisting of $2.5 million
in cash and forgiveness of the $1.25 million that we owe Tandberg. The
transaction does not involve a sale of our MCU business.

WHY HAS THE BOARD DECIDED TO SELL THE MCU PATENT PORTFOLIO?

    In light of our need of additional cash to continue operations and in
recognition of the unavailability of more favorable financing alternatives, our
board of directors has decided that the sale of the MCU patent portfolio
pursuant to the asset purchase agreement is in the best interests of Ezenia! and
its shareholders. The proposed transaction will provide us with a substantial
amount of cash in exchange for the transfer of title to, but not our right to
use, intellectual property relating to our MCU business, a portion of our
business that has become increasingly less important to us as the preferred mode
of corporate collaboration moves from proprietary systems to Web-based
implementation. The board of directors considered various benefits to approving
the transaction, including that the sale of the MCU patent portfolio would
provide capital to fund our operations and enable us to attempt to further
develop or sell our enterprise collaboration business. Our board of directors
also considered various negative factors concerning the sale of the MCU patent
portfolio to Tandberg pursuant to the asset purchase agreement and determined
that overall the risks associated with the transaction were outweighed by the
potential benefits of the sale.

WHAT OTHER OPTIONS DID EZENIA! CONSIDER BEFORE DECIDING TO SELL THE MCU PATENT
PORTFOLIO TO TANDBERG?

    Ezenia! explored possible financing and strategic alternatives, including
issuing additional equity securities, obtaining a loan secured by our assets and
selling all or a portion of the company. We were unable to identify any third
party willing to purchase our equity or make us a loan on acceptable terms, nor
were we able to negotiate the timely sale of the MCU patent portfolio with any
party other than Tandberg.

WHAT WILL OCCUR IF THE SALE OF THE MCU PATENT PORTFOLIO IS NOT APPROVED AND
CONSUMMATED?

    The board of directors does not believe that the long-term continued
operation of Ezenia! is feasible without additional capital. Therefore, if the
sale to Tandberg of the MCU patent portfolio is not approved, we must either
(1) pursue an infusion of capital or another transaction in which we can sell
all or a portion of our business on acceptable terms, or (2) if no such
transaction is found in the immediate future, liquidate the company under the
protection of federal or state bankruptcy laws. Given current market conditions
and our past experience, we think it unlikely that we would be able to conclude
an acceptable transaction in time to avoid liquidation of the company.

    If the sale of the MCU patent portfolio is not approved, we will be required
to repay the $1.25 million loan advanced to us by Tandberg, which is secured by
the MCU patent portfolio, and we

                                       7
<Page>
may not receive the additional $2.5 million payment that is due to us upon the
closing of the sale under the terms of the asset purchase agreement.

WHAT ARE THE FEDERAL TAX CONSEQUENCES OF THE SALE OF THE MCU PATENT PORTFOLIO?

    Ezenia! will recognize net taxable gains on the sale of the MCU patent
portfolio equal to the excess of the amount realized on the sale over the
aggregate adjusted basis in the assets sold, which gains we expect will be
offset by operating losses. The sale of the MCU patent portfolio will not, in
and of itself, cause our shareholders to recognize any income for federal income
tax purposes.

AM I ENTITLED TO APPRAISAL OR DISSENTER'S RIGHTS?

    No, under Delaware law, you are not entitled to exercise appraisal rights
for the proposed sale of the MCU patent portfolio pursuant to the asset purchase
agreement.

Exchange Act of 1934 and is required to file reports, proxy statements and other

                        SPECIAL MEETING OF SHAREHOLDERS

PURPOSE

    The specific proposal to be considered and acted upon at the special meeting
is summarized in the accompanying notice of special meeting of shareholders and
is described in more detail in this proxy statement.

TIME, DATE AND PLACE; SOLICITATION

    This proxy statement is furnished in connection with the solicitation by
Ezenia!'s board of directors of proxies for use at the special meeting of
shareholders to be held on Monday, October 21, 2002 at 10:00 a.m., EST, at the
offices of Bingham McCutchen LLP, 150 Federal Street, Boston, Massachusetts
02110, and any adjournments thereof.

RECORD DATE; REQUIRED VOTE; SHARES OUTSTANDING


    Only shareholders of record as of the close of business on September 3, 2002
will be entitled to notice of, and to vote at, the special meeting of
shareholders and any adjournments thereof. As of the record date there were
13,631,880 shares (excluding treasury shares) of our common stock, $.01 par
value, issued and outstanding. Such shares of common stock are the only voting
securities of Ezenia!. Shareholders are entitled to cast one vote for each share
of common stock held of record on the record date.


VOTING

    Registered shareholders can vote their shares (1) by mailing their signed
proxy card, (2) via a toll-free telephone call from the U.S. or Canada, (3) via
the Internet or (4) in person at the special meeting. The telephone and Internet
voting procedures are designed to authenticate shareholders' identities, to
allow shareholders to vote their shares and to confirm that their instructions
have been properly recorded. The company believes that the procedures that have
been put in place are consistent with the requirements of applicable law.
Specific instructions to be followed by any registered shareholder interested in
voting via telephone or the Internet are set forth on the enclosed proxy card.

    Shares represented by duly executed proxies received by us prior to the
special meeting will be voted as instructed in the proxy on each matter
submitted to the vote of shareholders. If any duly-executed proxy is returned
without voting instructions with respect to one or more proposal, the persons
named as proxies thereon intend to vote all shares represented by such proxy FOR
each such proposal and at their discretion with respect to any other proposals
that may properly come before the special meeting. The persons named as proxies
are employees of Ezenia!.


    Should there be any amendment to the asset purchase agreement after the
mailing of this proxy statement, each vote in favor of our proposed sale of the
MCU patent portfolio pursuant to the asset purchase agreement, unless revoked,
will be deemed a vote in favor of the transaction pursuant to the agreement as
so amended. We would notify shareholders to whom this proxy statement is mailed
if we were to agree to any amendment to the asset purchase agreement that we
deem material to the proposed sale.


REVOCABILITY OF PROXY

    Any shareholder may revoke a proxy at any time prior to its exercise (1) by
delivering a later-dated proxy, (2) by making an authorized telephone or
Internet communication on a later date in accordance with the instructions on
the enclosed proxy card, (3) by written notice of revocation to the secretary of
Ezenia! at our address set forth above or (4) by voting in person at the special

                 PROPOSAL: THE SALE OF THE MCU PATENT PORTFOLIO

DESCRIPTION OF EZENIA! AND ITS BUSINESS

    Ezenia! Inc. develops and markets products that enable organizations to
provide high-quality group communication and collaboration capabilities to
commercial, consumer and institutional users. Our products allow individuals and
groups that are geographically distant from each other to interact and share
information in a natural, spontaneous way--voice-to-voice, face-to-face,
flexibly and in real-time--via a wide range of networks. Using our products,
disparately located individuals can interact through a natural meeting
experience, allowing groups to work together effectively and disseminate vital
information quickly. Ezenia!'s products enable seamless connectivity across a
wide range of networks including LANs, intranets, the Internet, ISDN, ATM and
frame relay.

    Our traditional ISDN-based videoconferencing products use videoconferencing
interface components and telecommunications bridging equipment to facilitate
multipoint audio and video conferencing. We refer to our sales and services of
these products as our MCU business. As international telecommunications
standards for videoconferencing over switched digital circuit networks were
adopted in the early 1990s, a standard framework allowed equipment from
different manufacturers to communicate with each other over dial-up networks,
without regard to the type of equipment being used at the transmitting and
receiving ends of the session.

    With the growth of the Internet and the innovative technologies that
followed, real-time enterprise collaboration applications were developed and
introduced in the late 1990s. Real-time collaboration takes the best elements of
videoconferencing and joins them with the ubiquity and ease-of-use of the
Internet. Where videoconferencing requires expensive hardware and focuses on
quality video, real-time collaboration uses video when necessary but goes beyond
it by offering a more complete solution, enabling teams to work more effectively
from disperse locations. Real-time solutions often bring video and audio
conferencing to the desktop and can include such other features as integrating
data conferencing, whiteboarding, instant messaging and virtual meeting spaces.

    The focus of our enterprise collaboration business is our InfoWorkSpace
suite of Web-enabled collaboration and conferencing applications. The suite is a
Web-based package of collaborative solutions that facilitate communication, data
conferencing and knowledge management among dispersed members of a workgroup who
communicate with each other through a secure virtual workplace. InfoWorkSpace
products are currently used primarily by government organizations, including the
Department of Defense and the Intelligence community. While continuing to
develop the government business, we have attempted to market and sell
InfoWorkSpace products commercially.

    For the past several years, we have been shifting our focus toward
enterprise collaboration products and away from our traditional ISDN-based and
related IP-based videoconferencing products. For the six months ended June 30,
2001, revenues from our videoconferencing products and services were
$6.5 million (or approximately 96% of our total revenues), but had dropped to
$3.7 million (or approximately 63% of our total revenues) for the comparable
period ended June 30, 2002. MCU business revenues are expected to continue to
decrease significantly as we recently closed our foreign sales operations and
significantly reduced sales and service operations of our MCU business. Although
we propose to sell the patents, patent applications and certain related assets
relating to our MCU business, which together are referred to as the MCU patent
portfolio, following the proposed transaction, we will retain a fully paid,
worldwide, nontransferable license to use the technology covered by those
patents and patent applications. We will not be selling our MCU business to
Tandberg, and we will be permitted to continue to operate that business.
However, after the proposed sale of the MCU patent portfolio, we intend to offer
only limited sales and servicing of our MCU business products, and to direct
most of our resources to our enterprise collaboration business.

DESCRIPTION OF TANDBERG AND ITS BUSINESS

    Tandberg Telecom AS is a wholly owned subsidiary of Tandberg ASA, which is a
leading global provider of videoconferencing solutions. Tandberg ASA designs,
develops and manufactures videoconferencing systems and offers sales, support
and value-added services in more than 60 countries worldwide. Tandberg ASA is a
global company with offices in the United States, Norway, the United Kingdom,
Canada, China and Japan. Tandberg ASA is publicly traded on the Oslo Stock
Exchange under the ticker symbol "TAA." Tandberg Telecom AS is a corporation
organized under the laws of the Kingdom of Norway. Its principal executive
offices are located at Philip Pedersen's Vei 22, N-1324, Lysaker, Norway and its
telephone number is +47 67 125 125.


    According to a press release issued by Tandberg in July 2002, Tandberg's
total revenue for the fiscal year ended December 31, 2001 and for the fiscal
quarter ended June 30, 2002 were approximately 1,279 million Norwegian krone and
443 million krone (or approximately $166 million and $57 million, based on
current exchange rates), respectively, and Tandberg's total assets at the end of
each of those periods was approximately 2,319 million krone and 2,580 million
krone (or approximately $301 million and $335 million, based on current exchange
rates), respectively.


DESCRIPTION OF THE TRANSACTION

    On August 1, 2002, Ezenia! and Tandberg entered into several agreements to
enable Ezenia! to sell the MCU patent portfolio and certain related assets to
Tandberg and, in the meantime, obtain additional working capital. These
agreements consist of the following:

    LICENSE AGREEMENT.  We have granted to Tandberg a fully-paid, non-exclusive,
non-transferable, world-wide license to use, manufacture and distribute under
the MCU patent portfolio in exchange for an up-front payment by Tandberg of
$1.25 million. Under the license agreement, Tandberg is permitted to grant
sublicenses to its affiliates, resellers, distributors, manufacturers and
end-users in connection with the manufacture, sale, servicing and use of the
Tandberg products. The license terminates if the sale of the MCU patent
portfolio does not close due to breach by Tandberg of the asset purchase
agreement, provided that the termination will be effective only if we reimburse
Tandberg the $1.25 million license fee on or before December 31, 2002.

    RISK ALLOCATION AGREEMENT.  Tandberg has agreed to indemnify us against
certain losses and liabilities incurred by us as a result of infringements or
other claims relating to Tandberg's products.

    PROMISSORY NOTE.  We have agreed to repay the $1.25 million loaned to us by
Tandberg, together with interest at an annual rate of 7.5% (with a penalty
interest rate of 18% for amounts not paid when due), not later than October 31,
2002. We will be in default under the promissory note if, among other things, we
fail to make a payment when due, we dissolve or become insolvent, we are the
subject of a bankruptcy or reorganization proceeding, we transfer or attempt to
transfer all or substantially all of our assets, a foreclosure proceeding or the
like is commenced against us, a substantial part of our business or property is
seized or condemned, an event of default occurs under the security agreement or
we breach the license agreement or the asset purchase agreement. All amounts
owing under the promissory note are to be forgiven upon the closing of the sale
of the MCU patent portfolio to Tandberg.

    SECURITY AGREEMENT.  We have granted Tandberg a security interest in the MCU
patent portfolio to secure our payment obligations under the promissory note. If
we default under the promissory note or under the security agreement (including
by breaching the license agreement or the asset purchase

                                       12
<Page>
agreement), Tandberg may foreclose on and sell the MCU patent portfolio in an
effort to collect the amounts we owe Tandberg.

    ASSET PURCHASE AGREEMENT.  Please see the summary below. You should refer to
the full text of the asset purchase agreement, attached to this proxy statement
as Annex A, for details of the terms and conditions thereof.

      to permit Tandberg an opportunity to cure.

    EXPENSES

    We and Tandberg are required to pay our own expenses and costs incurred in
connection with the asset purchase agreement.

USE AND SUFFICIENCY OF SALE PROCEEDS

    The purpose and goal of our sale of the MCU patent portfolio are to use the
proceeds from the sale for general operating expenses in an effort to build and
increase the value of our enterprise collaboration business or to attempt to
dispose of that business.

    As we have previously reported, after the July 2002 restructuring and the
relocation of our headquarters, which are described below, we estimate our
cash-flow breakeven point to be approximately $3.5 million in revenues per
quarter, with future revenues expected to be generated primarily from sales and
services associated with our InfoWorkSpace products. We have no long-term debt
and no current expansion plans. Accordingly, we would expect to be able to fund
our long-term liquidity requirements from operating revenues if we are able to
satisfy our short-term obligations.

    We anticipate the proceeds from the sale of the MCU patent portfolio to
enable us to continue to fund operations through the first half of 2003,
assuming we are able to significantly extend our obligation to purchase
$2.9 million of our common stock in December 2002 upon exercise of the put
option that we issued in connection with our acquisition of the InfoWorkSpace
business. We cannot be sure that we will be able to renegotiate the terms of the
put option. Further, while we forecast revenues in excess of our projected
breakeven point by the second half of 2003, we are not certain that we will be
generating sufficient revenue from our InfoWorkSpace products to fund continuing
operations by the time that we exhaust the proceeds from the sale of the MCU
patent portfolio.

    Therefore, in an effort to maximize the value of our common stock, we are
assessing whether the capital requirements and competitive risks associated with
developing our enterprise collaboration products outweigh the value that we
might realize from a near-term sale of that business. We are attempting to hire
an investment banker to assist in investigating and assessing possible sale
opportunities. However, we have no current plan, proposal or arrangement to sell
our enterprise collaboration business.

BACKGROUND OF THE SALE OF THE MCU PATENT PORTFOLIO

    Beginning in the spring of 2001, we began exploring strategic alternatives
in the face of significant internal restructuring, senior management turnover,
declining financial results and competitive challenges in the MCU business.
Since that time, we have also reported that our ability to continue as

                                       16
<Page>
a going concern is dependent upon our ability to raise additional capital,
increase revenue or substantially improve operating margins.

    In May 2001, we adopted a restructuring and cost reduction plan to align
company resources and expenses with our sharpened focus on our enterprise
collaboration business. We continued to implement this plan over the remainder
of 2001, but revenues have not materialized in line with our expectations. As a
result, in July 2002, we implemented another restructuring and cost reduction
plan which consisted of the termination of 55 employees (approximately 50% of
our work-force), closing our foreign sales operations, relocating our
headquarters to smaller facilities in Burlington, Massachusetts and
significantly reducing sales and service operations of our MCU business.

    In April 2001, through our own efforts and through the preliminary efforts
of an investment adviser, we began to seek out and investigate possible
financing or strategic alternatives. Through the spring of 2002, however,
neither we nor our investment adviser was able to identify any third party
interested in entering into an acceptable strategic or lending relationship with
Ezenia!. Throughout this process, our management kept our board of directors
apprised of the status of possible strategic alternatives. The directors
instructed management to continue to seek out and evaluate opportunities.

    In March 2002, we engaged a financial adviser to help us identify third
parties who might make us a loan secured by some of our patents. In connection
with that effort, our advisor engaged PLX Systems Incorporated to provide an
indication of the market value of seven patents included in the MCU patent
portfolio. We have no relationship with PLX Systems, which is a company that is
regularly engaged to provide enterprise-wide, customized intellectual property
valuation appraisals in a variety of scenarios including asset securitization,
mergers and acquisition activity, licensing and intangible asset accounting. We
reimbursed our financial adviser $20,000 for amounts paid to PLX Systems for
their valuation services. The valuation report, which was delivered to our
financial adviser on April 17, 2002, indicated that the market value of the
appraised patents was $56.7 million. A copy of this report will be made
available for inspection and copying at our principle corporate offices during
our regular business hours by any interested holder of our common stock or its
representative who has been so designated in writing.

    The methodology underlying the valuation combines option pricing theory and
current, per-product data from publicly traded, technology-specific companies to
assess the value of intellectual property assets relating to future products.
This approach values the patents as if they were call options on future
technology assets and applies the Black-Scholes model to determine present
value. The Black-Scholes model is a mathematical approach typically used to
determine the value of option contracts, based on variables such as the
volatility of a security's return, the level of interest rates, the relationship
between the price of the underlying security and the exercise price of the
option and the exercisable period of the option. Variables considered by PLX
Systems in applying the Black-Scholes model to the valuation of the MCU patent
portfolio included both subjective factors, such as time until launch,
development cost and market-driven product value, and objective factors, such as
time until patent expiration and the rate of the five-year U.S. government bond.

    In performing its analysis, PLX System had to make certain assumptions, some
of which were based on information that we provided, such as our estimate that
the technology underlying these patents, when fully developed, would rank in the
90th percentile among competing technologies in the same niche and that
remaining development costs would be approximately $500,000. Additionally, the
appraisal assumes, among other things, that there is no time to product launch,
that the cost of development is paid out instantly at the time of product
launch, that the highest and best use of the technology has been properly
identified and is realizable by Ezenia!, and that our ownership and the validity
of our patents is certain. The analysis assumes the accuracy of information
available from public sources, some of which, such as trading prices of public
companies, is given as of a particular

                                       17
<Page>
point in time. Inaccuracies in the assumptions and other information used in the
analysis can significantly affect the accuracy of the appraisal.

    Our financial adviser informed us that it contacted at least four financial
institutions regarding the possibility of obtaining a loan secured by the
appraised assets. Initially, the adviser expected to be able to secure a
financing commitment by the end of April 2002. However, as of July 2002, none of
the financial institutions expressed a willingness to enter into any financing
arrangements with Ezenia!. One institution discussed loaning us up to a total of
$8 million in stages, but decided not to proceed with the transaction.

    During this period, we also contacted Cisco Systems, Inc., Tandberg and
Polycom, Inc. to assess their level of interest in purchasing our MCU patent
portfolio or the entire MCU business. One company indicated potential interest
at a price of approximately $3.5 million, but expressed no willingness to
negotiate, even when informed that we were engaged in serious discussions with
another party. Tandberg was the only company to express a substantial interest
in purchasing the MCU patent portfolio and in promptly pursuing a transaction.

    Also, in late April 2002, Ezenia! received an unsolicited offer to acquire
all of our outstanding shares for approximately $1 million in cash and
approximately $3 million in shares of a company with stock trading on the OTC
Bulletin Board. While we provided the interested company with access to
information concerning Ezenia!, discussions relating to the disposition of our
MCU patent portfolio presented a more favorable opportunity.

    On July 25, 2002, Ezenia! and Tandberg informally agreed to a value of
$5 million for the MCU patent portfolio. Over the following several days, we and
Tandberg negotiated the structure and details of the transaction, under which
Tandberg paid us $1.25 million in cash, at that time, for a non-exclusive
license under the MCU patent portfolio and agreed to pay us an additional
$3.75 million upon our transfer of title to those patents and patent
applications, following approval of the transaction by our shareholders. The
additional $3.75 million is to consist of $2.5 million in cash and forgiveness
of the $1.25 million that Tandberg loaned to us in connection with this
transaction.


    Despite the higher valuation stated in the appraisal report, we believe that
the current market value of the MCU patent portfolio (that is, what a willing
buyer would pay for it) is only a fraction of the appraised amount. There are
only a limited number of companies worldwide that compete in the ISDN-based
videoconferencing products market. We contacted and attempted to enter into
negotiations with the companies we thought might be interested in our MCU
business or the MCU patent portfolio. However, other videoconferencing companies
have their own products and technologies, and few were interested in entering
into a transaction with us. As discussed above, Tandberg provided the best offer
available to Ezenia!. Tandberg's $5 million offer was higher than the
$3.5 million proposal suggested by another potential purchaser and higher than
the offer of $4 million for the entire company. Further, no debt financing was
available to us.


    On July 29, 2002, at a special meeting of Ezenia!'s board of directors, our
management and legal counsel presented to the board of directors the state of
negotiations with Tandberg, as well as the proposed structure of the
contemplated transaction and the principal terms of the asset purchase agreement
and the other related documents. The board of directors also reviewed
alternatives available to Ezenia! at that time. At the conclusion of this
meeting, in light of Ezenia!'s need of cash in order to continue operations and
in recognition of the unavailability of more favorable financing alternatives,
the board of directors unanimously approved Ezenia!'s granting Tandberg a
non-exclusive license under the MCU patent portfolio, accepting a loan from
Tandberg secured by that intellectual property and, subject to Ezenia!
shareholder approval, selling the MCU patent portfolio to Tandberg.

    On August 1, 2002, the company and Tandberg executed the asset purchase
agreement and related documentation.

EZENIA!'S REASONS FOR THE SALE OF THE MCU PATENT PORTFOLIO

    Ezenia!'s board of directors unanimously determined that the sale of the MCU
patent portfolio pursuant to the asset purchase agreement is expedient and in
the best interests of Ezenia! and its shareholders and unanimously recommends
that the shareholders approve the sale of the MCU patent portfolio pursuant to
the asset purchase agreement.

    The board of directors believes that the sale of the MCU patent portfolio
will be beneficial to Ezenia! and its shareholders and considered a number of
positive factors in reaching this conclusion, including the following:

    - That if we do not sell the MCU patent portfolio we will likely be unable
      to continue to fund our operations and will be required to repay the loan
      we received from Tandberg;

    - That the cash consideration that we will receive in connection with the
      sale of the MCU patent portfolio will provide us with additional time to
      try to maximize the value of our enterprise collaboration business, either
      by enabling us to attempt to build and increase the value of that business
      as an ongoing operation or by providing us with additional time to attempt
      to dispose of that business;

    - That the sale of the MCU patent portfolio enables us to receive a
      substantial amount of cash for intellectual property rights relating to a
      portion of our business that has become increasingly less important to us
      as the preferred mode of corporate collaboration moves from proprietary
      systems to Web-based implementation;

    - That the cash consideration that we will receive in connection with the
      sale of the MCU patent portfolio far exceeds the total value of all of our
      outstanding shares, based on the recent trading prices of our common
      stock;

    - That, based on the history of our discussions with other parties, no other
      transaction involving the MCU business is likely to be more favorable to
      us and our shareholders;

    - That the asset purchase agreement enables us to retain a fully-paid,
      non-exclusive, non-transferable license under the MCU patent portfolio,
      enabling us to use the intellectual property covered by those patents and
      patent applications in connection with our operation of our MCU and
      enterprise collaboration businesses; and

    - That the terms of the asset purchase agreement are reasonable and do not
      contain any extraordinary conditions, such as a financing contingency, to
      Tandberg's obligation to close the purchase of the MCU patent portfolio.

    The board of directors also considered a number of potentially negative
factors in its deliberations concerning the sale of the MCU patent portfolio,
including:

    - That the consummation of the sale of the MCU patent portfolio is
      conditioned upon a number of factors including: approval by our
      shareholders, the accuracy of the representations and warranties of the
      parties and compliance by the parties with their obligations under the
      asset purchase agreement, and absence of a material adverse change related
      to the MCU patent portfolio;

    - That the failure of the sale to be consummated for any reason would likely
      render Ezenia! unable to pay its obligations and could result in our
      ceasing operations and/or filing for bankruptcy protection; and that if we
      are unable to repay the $1.25 million that we owe to Tandberg pursuant to
      the promissory note, Tandberg could foreclose on and cause the sale of the
      MCU patent portfolio;

                                       19
<Page>
    - That after the consummation of the sale of the MCU patent portfolio, we
      intend to focus heavily on our enterprise collaboration business; that as
      a result, our total revenues will be lower than they are currently; and
      that while we believe that the enterprise collaboration business has
      growth potential, to date that business has not generated a profit and has
      incurred significant operating losses;

    - That the proceeds of the sale may not be sufficient to enable us to
      operate our enterprise collaboration business long enough to generate
      revenue sufficient to fund continuing operations;

    - That we have agreed to indemnify Tandberg against certain losses to
      satisfy claims for the payment of these losses should they arise;

    - That the asset purchase agreement provides, in effect, that Tandberg and
      parties related to Tandberg may, without additional payment to us, use
      certain intellectual property subject to any videoconferencing patents
      that we may file prior to August 1, 2004; and

    - That we will remain responsible for preclosing liabilities relating to our
      ownership of the MCU patent portfolio.

    The board of directors believed that certain of these negative factors were
unlikely to occur or unlikely to have a material impact on Ezenia!, while we
could avoid or mitigate others, and that overall, the risks associated with the
sale of the MCU patent portfolio to Tandberg were outweighed by the potential
benefits of the sale.

    The foregoing discussion of information and factors considered by the board
of directors is not intended to be all-inclusive. In view of the wide variety of
factors considered, the board of directors did not find it practicable to
quantify or otherwise assign relative weight to the specific factors considered.
However, after taking into account all of the factors set forth above, the board
of directors unanimously determined that the sale of the MCU patent portfolio
was expedient and in the best interests of Ezenia! and its shareholders and that
the company should proceed with the sale of the MCU patent portfolio.

RECOMMENDATION OF EZENIA!'S BOARD

    FOR THE REASONS DISCUSSED ABOVE, THE BOARD OF DIRECTORS HAS UNANIMOUSLY
APPROVED THE SALE OF THE MCU PATENT PORTFOLIO PURSUANT TO THE ASSET PURCHASE
AGREEMENT AND THE RELATED AGREEMENTS AND HAS DETERMINED THAT THE SALE OF THE MCU
PATENT PORTFOLIO IS EXPEDIENT AND IN THE BEST INTERESTS OF EZENIA! AND ITS
SHAREHOLDERS. ACCORDINGLY, THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT
THE SHAREHOLDERS VOTE FOR APPROVAL OF THE SALE OF THE MCU PATENT PORTFOLIO
PURSUANT TO THE ASSET PURCHASE AGREEMENT.

ACCOUNTING TREATMENT

    The proposed sale of the MCU patent portfolio is expected to be accounted
for as a sale of certain assets, in accordance with accounting principles
generally accepted in the United States. In the period in which the proposed
sale of the MCU patent portfolio is consummated, we expect to recognize a gain
in the amount of the difference between the sale price and the aggregate book
value of the net assets sold.

                                       20

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES

    The following discussion summarizes certain U.S. federal income tax
consequences of the sale of the MCU patent portfolio. The discussion is based on
the Internal Revenue Code, Treasury Regulations, existing administrative
interpretations and court decisions, all of which may change, possibly with
retroactive effect. This discussion is not a complete analysis or description of
every potential U.S. federal income tax consequence, and does not address any
consequences under state, local or foreign tax laws or non-income tax laws.

    TAX CONSEQUENCES FOR EZENIA!

    We will recognize net taxable gains on the sale of the MCU patent portfolio
equal to the excess of the amount realized on the sale over our aggregate
adjusted basis in the assets sold. Although the gains will constitute capital
gains, to the extent that we hold the MCU patent portfolio as capital assets, we
expect that the gains will be offset by operating losses incurred during 2002,
and/or by net operating loss carry-forwards from previous taxable years. The
losses and/or loss carry-forwards so absorbed will not be available to offset
income and gains that we may realize in the future.

    TAX CONSEQUENCES FOR EZENIA!'S SHAREHOLDERS

    The sale of the MCU patent portfolio will not, in and of itself, cause our
shareholders to recognize any income for federal income tax purposes. The sale
will generate "earnings and profits" for tax purposes. Though not anticipated,
if we have positive earnings and profits for our 2002 taxable year, then some or
all of the distributions or deemed distributions made by us to shareholders
during 2002, if any, may be treated as taxable dividends.

REGULATORY APPROVALS

    No federal or state regulatory requirements must be complied with and no
third-party approvals must be obtained in connection with our sale of the MCU
patent portfolio or any of the transactions contemplated by the asset purchase
agreement and related agreements.

DISSENTERS' RIGHTS OF APPRAISAL

    Under the Delaware General Corporation Law, our shareholders are not
entitled to rights of appraisal in connection with the sale of the MCU patent
portfolio or any of the transactions contemplated by the asset purchase
agreement and the related agreements.


PAST CONTRACTS, TRANSACTIONS OR NEGOTIATIONS



    Ezenia! is not an affiliate of Tandberg or any of its affiliates. Other than
the agreements that we entered into with Tandberg in connection with the
proposed sale of the MCU patent portfolio, our only relationships with Tandberg
or its affiliates have been commercial arrangements entered into in the ordinary
course of business. During the period from 1996 to the present, Tandberg and
certain of its affiliates have been authorized resellers of our ISDN- and
IP-based videoconferencing products pursuant to reseller agreements containing
standard terms and conditions typical of our reseller agreements.

                               VOTING PROCEDURES

    The affirmative vote of a majority of the outstanding shares of our common
stock is required for the approval of the sale of the MCU patent portfolio. For
purposes of determining whether a proposal has received a majority vote,
abstentions will be included in the vote totals, with the result being that an
abstention will have the same effect as a negative vote. In instances where
brokers are prohibited from exercising discretionary authority for beneficial
holders who have not returned a proxy (so-called "broker non-votes"), those
shares will not be included in the vote totals and, therefore, will also have
the same effect as a negative vote. Shares that abstain or for which the
authority to vote is withheld on certain matters will, however, be treated as
present for quorum purposes on all matters.

                                 OTHER BUSINESS

    The board of directors knows of no business which will be presented for
consideration at the special meeting other than that stated above. If other
business should come before the special meeting, the persons named in the
proxies solicited hereby, each of whom is an employee of the company, may vote
all shares subject to such proxies with respect to any such business in the best
judgment of such persons.

                             SHAREHOLDER PROPOSALS

    It is currently contemplated that the 2003 Annual Meeting of Shareholders
will be held on or about May 21, 2003. Proposals of shareholders intended for
inclusion in the proxy statement to be furnished to all shareholders entitled to
vote at the next annual meeting of the company and/or for inclusion in the
agenda for that meeting must be received at the company's principal executive
offices not later than December 19, 2002. It is suggested that proponents submit
their proposals by certified mail, return receipt requested.

described on the disclosure schedules attached hereto and incorporated herein
shall be set forth with reference to each separate Section of this Agreement to
which the matter relates.

duly incorporated and validly existing and in good standing under the laws of

contemplated hereby are or, upon the execution and delivery thereof will be, the
valid and binding obligations of the Seller, enforceable against it in
accordance with their terms, subject to any limitation of enforceability that
may be imposed by applicable bankruptcy, insolvency, fraudulent conveyance,
reorganization, moratorium or other similar laws affecting creditor's rights and
remedies generally and by the application by a court of equitable jurisdiction

    limited to payment of any and all issuance fees, maintenance fees and
    annuities.

    to any outstanding injunction, judgment, order, decree, ruling, or charge;
    (ii) no action, suit, opposition or reexamination proceeding, hearing,
    investigation, charge, complaint, claim, or demand is pending or, to the

    enforceability, use, or ownership of the Patent; (iii) no person has
    notified the Seller of any claim concerning any alleged interference,
    infringement, misappropriation, reexamination, opposition or other conflict
    of any of the Patents with the intellectual property of any third party; and
    (iv) the Seller has no Knowledge of any state of facts or contemplated event
    that may give rise to any claim, action, suit, proceeding, complaint,
    investigation or inspection which could adversely affect the ownership,
    validity or use of the Purchased Assets.

        (d) The Seller has no Knowledge of any products, inventions or
    procedures of competitors which infringe or misappropriate any Patent and
    has not given any notice of infringement or sent any demand to "cease and

necessary or appropriate to maintain its right, title and interest in and to the
Purchased Assets. The Seller shall pay all costs related to the same. Commencing

except for licenses granted to customers of Seller in conjunction with the

Seller will, and will instruct its agents and representatives to, give Buyer and
its employees, agents or representatives access to the Documentation and permit

continuing prosecution of the any pending Patents following Closing. All such
access and inspections will be conducted during Seller's (or its patent

the Seller shall comply with all applicable laws, statutes, ordinances, rules,

could reasonably be expected to materially adversely affect the Purchased
Assets.

    6.4  SUPPLEMENTAL DISCLOSURE.  As it becomes aware of such information and
in any event not later than the Closing Date, the Seller shall inform the Buyer
in writing of all information, events or actions which, if this Agreement were
signed on the Closing Date, would be required to be disclosed on the Schedules
in order to make the Seller's representations and warranties contained herein
true and not misleading. The delivery thereof by the Seller shall not absolve
the Seller from liability for breach of any representation or warranty which was
untrue when made.

                                      A-5

requested to more effectively transfer and vest in the Buyer, the Purchased
Assets pursuant to the terms of this Agreement or to otherwise carry out the
terms and conditions of this Agreement.

    6.8  CONFIDENTIALITY.  The Purchased Assets and the Documentation constitute

Affiliates in violation of this Section 6.8); (b) information that is disclosed

Affiliates or their respective, contract manufacturers, distributors, resellers
or customers in connection with their relationship with Buyer (the "Covered
Parties"), any Relevant Rights; provided that this covenant does not extend to
any attempt by any of the Covered Parties to contest the validity of any patents
contained within the Relevant Rights or to obtain for itself or others patent
rights with respect to such Relevant Rights. In the event Seller seeks to sell,
assign, transfer or license (but only if such license permits the licensee to
assert enforcement rights with respect to) any of its Relevant Rights to a third
party after the Closing, Seller shall notify Buyer of such proposed sale and
shall obtain the written undertaking from such party to abide by the terms of
this covenant. As used herein "Relevant Rights" shall mean any patent or patent
applications with respect to any intellectual property within the Field, owned
or controlled by Seller or its successors or assigns, that was filed on or
before the second anniversary of the Effective Date.

                     ARTICLE 10--INDEMNIFICATION BY SELLER

    10.1  INDEMNIFICATION.  Notwithstanding the Closing, and regardless of any
investigation made by or on behalf of the Buyer or any information known to the
Buyer, the Seller, subject to the terms and conditions of this Article 10,
indemnifies and saves the Buyer, its shareholders, officers, directors and/or
employees (collectively, the "Buyer" as used in this Article 10) harmless from
and against any and all losses, claims, damages, actions, liabilities, costs,
expenses or deficiencies including, but not limited to, reasonable attorneys'
fees and other costs and expenses reasonably incident to proceedings or
investigations or the defense or settlement of any claim or claims, incurred by
or asserted against the Buyer or the Purchased Assets due to or resulting from
any of the following: (a) the inaccuracy or breach of any representation or
warranty of the Seller given in or pursuant to this Agreement; (b) any breach or
default in the performance by the Seller of any of its covenants, obligations or
agreements in or pursuant to this Agreement; (c) any liability or obligation of
the Seller not expressly assumed by the Buyer pursuant to this Agreement; or
(d) the ownership or use of the Purchased Assets at any time prior to the
Closing, or any incident, occurrence, condition or claim existing, arising or
accruing prior to the Closing and relating to the ownership or use of the
Purchased Assets. The foregoing are collectively referred to as "Indemnifiable
Damages." The term "Indemnifiable Damages" shall also include an amount of
interest on the amount of such Indemnifiable Damages (computed before the
application of this sentence), which interest shall be computed at the
Applicable Rate in simple interest per annum from the Closing Date and until
paid by the Seller. Notwithstanding the Closing, and regardless of any
investigation made by or on behalf of the Seller or any information known to the
Seller, the Buyer, subject to the terms and conditions of this Article 10,
indemnifies and saves the Seller, its shareholders, officers, directors and/or
employees (collectively, the "Seller" as used in this Article 10) harmless from
and against any and as Indemnifiable Damages incurred by or asserted

                                      A-8
<Page>
against the Seller due to or resulting from any of the following: (a) the
inaccuracy or breach of any representation or warranty of the Buyer given in or
pursuant to this Agreement; or (b) any breach or default in the performance by
the Buyer of any of its covenants, obligations or agreements in or pursuant to
this Agreement.

    10.2  LIMITATION ON INDEMNIFICATION OBLIGATION.  The Seller will not have
any obligation to indemnify or save harmless the Buyer from and against any
Indemnifiable Damages in excess of the Purchase Price (or such portion thereof
as the Buyer shall then have paid to the Seller).

    10.3  PROCEDURE FOR INDEMNIFICATION WITH RESPECT TO NON-THIRD PARTY
CLAIMS.  In the event that the Indemnified Party asserts a claim (a "Notice of
Claim") for Indemnifiable Damages (but excluding a claim for Indemnifiable
Damages resulting from the assertion of liability by third parties), it shall
give written notice to the Indemnifying Party specifying the nature and amount
of the Indemnifiable Damages. If the Indemnifying Party, within 15 business days
after receipt of such Notice of Claim by the Indemnified Party, has not given
written notice (a "Notice of Objection") to the Indemnified Party announcing its
intent to contest such assertion by the Indemnified Party, such assertion shall
be deemed accepted and the amount of Indemnifiable Damages stated in the Notice
of Claim shall be deemed a valid c therefor. In the event, however, that the
Indemnifying Party contests the assertion of a Notice of Claim by delivering a
Notice of Objection to the Indemnified Party within such 15 business day period,
then if the parties, acting in good faith, cannot reach agreement with respect
to such claim within 20 days after such notice, the contested assertion of the
claim shall be referred to arbitration in Wilmington, Delaware, in accordance
with the then-current rules of the American Arbitration Association. The
determination made in accordance with such rules shall be delivered in writing
to the parties and shall be final and binding and conclusive on the parties and
the amount of damages, if any, determined to exist shall be valid Indemnifiable
Damages. Each party shall pay its own legal, accounting and other fees in
connection with such a contest.

    10.4  PROCEDURE FOR INDEMNIFICATION WITH RESPECT TO THIRD PARTY CLAIMS.  If
any third party notifies the Indemnified Party with respect to any matter that
may give rise to a claim for indemnification against the Indemnifying Party
under this Article 10, then the Indemnified Party will notify the Indemnifying
Party thereof promptly and in any event within 30 days after receiving any
written notice from a third party; provided that no delay on the part of the
Indemnified Party in notifying the Indemnifying Party will relieve the
Indemnifying Party from any obligation hereunder unless, and then solely to the
extent that, the Indemnifying Party is prejudiced thereby. Once the Indemnified
Party has given notice of the matter to the Indemnifying Party, the Indemnified
Party may defend against the matter in any manner it reasonably may deem
appropriate. In the event the Indemnifying Party notifies the Indemnified Party
within 30 days after the date the Indemnified Party has given notice of the
matter that the Indemnifying Party is assuming the defense of such matter
(a) the Indemnifying Party will defend the Indemnified Party against the matter
with counsel of its choice reasonably satisfactory to the Indemnified Party,
(b) the Indemnified Party may retain separate counsel at its sole cost and
expense (except that the Indemnifying Party will be responsible for the fees and
expenses of such separate co-counsel to the extent the Indemnified Party
concludes in good faith that the counsel the Indemnifying Party has selected has
a conflict of interest), (c) the Indemnified Party will not consent to the entry
of a judgment or enter into any settlement with respect to the matter, or take
any measure that imposes any burden or encumbrance upon the conduct of the
Indemnified Party or its operations, without the written consent of the
Indemnifying Party (not to be withheld or delayed unreasonably), (d) the
Indemnifying Party will not consent to the entry of a judgment with respect to
the matter or enter into any settlement that does not include a provision
whereby the plaintiff or claimant in the matter releases the Indemnified Party
from all liability with respect thereto, without the written consent of the
Indemnified Party (not to be withheld or delayed unreasonably), and (e) the
Indemnified Party shall have the right to attend, at its own expense, any
meetings relating to, and to receive upon request

                                      A-9
<Page>
copies of all correspondence, reports or other documents submitted or received
by or on behalf of the Indemnifying Party in connection with, the defense of
such matter.

    10.5  SURVIVAL OF REPRESENTATIONS AND INDEMNIFICATION.  The Seller's
obligation to pay Indemnifiable Damages and to comply with this Article 10 shall
survive the Closing of this transaction for a period of three (3) years.

    10.6  OTHER INDEMNIFICATION PROVISIONS.  The foregoing indemnification
provisions are in addition to, and not in derogation of, any statutory,
equitable, or common law remedy the Buyer may have with respect to the Seller,
or the transactions contemplated by this Agreement.

                            ARTICLE 11--TERMINATION

    11.1  RIGHTS TO TERMINATE.  This Agreement may be terminated at any time
prior to the Closing only as follows:

        (a) by mutual written consent of the Seller and the Buyer;

    in breach of any representation, warranty or covenant under this Agreement
    and fails to cure such breach, if curable, within ten (10) days after
    receipt of notice from the Seller requesting that such breach be cured (and
    the Seller is not then in breach of any representation, warranty or
    covenant);

        (c) by the Buyer by giving written notice to the Seller if the Seller is
    in breach of any representation, warranty or covenant under this Agreement
    and fails to cure such breach, if curable, within ten (10) days after
    receipt of notice from the Buyer requesting that such breach be cured (and
    the Buyer is not then in breach of any representation, warranty or
    covenant); or

        (d) by the Buyer by giving written notice to the Seller if the Closing
    shall not have occurred by October 31, 2002, unless the failure of the
    Closing to have occurred by such date is due to a material breach on the
    part of the Buyer which Buyer has failed to cure within ten (10) days after
    receipt of notice from the Seller requesting such breach be cured; PROVIDED
    that, if such cure period extends to or beyond October 31, 2002, the
    requirement to close by such date shall be extended for so long as required
    (up to 10 days) to permit the Closing to occur after Buyer has had an
    opportunity to cure.

        (e) Each party's right to termination pursuant to this Section 11 is in
    addition to any of the rights it may have hereunder or otherwise.

    11.2  EFFECTS OF TERMINATION.  Notwithstanding any other provision of this
Agreement, no termination of this Agreement shall release any party of any
Liability arising hereunder for any pre-termination breach hereof or intentional
