                              SYNC RESEARCH, INC.

Dear Stockholder:

    As most of you are aware, Sync has entered into an agreement with Osicom
Technologies, Inc., (doing business as Entrada Networks and referred to herein
as "Entrada" or "Osicom"), a Delaware corporation and wholly-owned subsidiary of
Osicom Technologies, Inc, a New Jersey corporation that is publicly held
(Nasdaq: FIBR) (referred to herein as "Parent"). As a result of this pending
transaction, we have delayed our annual meeting of stockholders in order to
incorporate this very important matter. Our meeting is scheduled to be held at
      local time, on Monday, August 14, 2000, at             .

    We cannot complete the merger unless the holders of a majority of the shares
of Sync common stock voting at the meeting vote in person or by proxy to
authorize the issuance of shares of Sync common stock under the merger
agreement. Only stockholders who hold shares of Sync common stock at the close
of business on Friday, June 30, 2000 will be entitled to vote at the annual
meeting. The Sync board of directors has unanimously approved the merger
agreement and recommends that you vote FOR the proposal to issue shares of Sync
common stock under the merger agreement so that the merger transaction may be
completed.

    We believe that the combination of Sync and Entrada will allow Sync to
significantly improve its operating results. In addition, the merger represents
a significant business opportunity to enter into the emerging and rapidly
growing market for data storage systems (a.k.a. storage area networks or SANs).
Entrada has already begun the implementation of a strategy for the SAN market
and has SAN products currently in development. We believe that the complementary
technologies, combined resources, expected synergies, experience and market
position of Sync and Entrada, with established relationships with key original
equipment manufacturers and large enterprise customers, create a unique platform
for growth and significant long-term stockholder value.

    In addition, we believe that the merger significantly strengthens our
capabilities by leveraging Parent's past experience in successfully developing
communications technology companies. For example, NETsilicon, Inc., a company
acquired for $5 million by Parent in 1996, has a market capitalization as of May
17, 2000 of more than $265 million after Parent helped it develop a new business
model. Another subsidiary of Parent, Sorrento Networks, has been rebuilt by
Parent from a maker of relatively slow-growth video networking products into a
pioneer in the field of all-optical networking products for metropolitan or
intra-city networks, a market with substantial opportunities for growth.

    The proposed transaction involves the issuance of Sync common stock to
Parent for all of the outstanding common stock of Entrada. After the merger,
Sync will own all of the outstanding common stock of Entrada, and Parent will
own 50% of the outstanding Sync common stock. Details of the proposed merger,
important information concerning Sync and Entrada, and information concerning
other important proposals to be considered at the special meeting appear in the
accompanying proxy statement/prospectus. We urge you to give this material your
careful and dedicated consideration.

    YOU SHOULD CONSIDER THE MATTERS DISCUSSED UNDER "RISK FACTORS RELATING TO
THE MERGER" COMMENCING ON PAGE 15 OF THE ENCLOSED PROXY STATEMENT/PROSPECTUS
BEFORE VOTING. PLEASE REVIEW CAREFULLY THE ENTIRE PROXY STATEMENT/PROSPECTUS.

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q.  WHY IS SYNC PROPOSING TO ENTER INTO THIS MERGER?

A. We believe that the combination of Sync and Entrada will allow Sync to
    significantly improve its operating results. In addition, the merger
    represents a significant business opportunity to enter into the emerging and
    rapidly growing market for data storage systems (a.k.a. Storage Area
    Networks or SANs). Entrada has already begun the implementation of a
    strategy for the SAN market and has SAN products currently in development.
    We believe that the complementary technologies, combined resources, expected
    synergies, experience and market position of Sync and Entrada, with
    established relationships with key original equipment manufacturers and
    large enterprise customers, create a unique platform for growth and
    significant long-term stockholder value.

   In addition, we believe that the merger significantly strengthens our
    capabilities by leveraging Parent's past experience in successfully
    developing communications technology companies. For example, Parent's
    networking system-on-silicon subsidiary, NETsilicon, Inc., was acquired by
    Parent in 1996 for $5 million. As of May 17, 2000, after Parent helped it
    develop a new business model, and after a September 1999 spinoff via an
    initial public offering, NETsilicon has a market capitalization of more than
    $265 million. Parent's other major subsidiary is Sorrento Networks, which
    Parent has rebuilt from a maker of relatively slow-growth video networking
    products into a pioneer in the field of all-optical networking products for
    metropolitan or intra-city networks, a market with substantial opportunities
    for growth.

Q.  WHAT WILL THE PARENT OF ENTRADA RECEIVE IN THE MERGER?

A. In the merger, the parent of Entrada (which we will refer to as "Parent"
    throughout this proxy statement/prospectus), which is the sole holder of
    Entrada common stock, will receive a number of shares of Sync common stock
    equal to 50% of the outstanding Sync common stock after the merger.

Q.  HOW WILL THE MERGER BE ACCOMPLISHED, AND WHAT WILL BE ITS IMPACT ON THE
    COMPANIES?

A. The respective boards of directors of Sync, Entrada and Parent have each
    approved the merger. If the Sync stockholders authorize the issuance of Sync
    common stock under the merger agreement at the annual meeting, then Entrada
    will merge with a wholly-owned subsidiary of Sync, with Entrada remaining as
    the surviving entity. Upon completion of the merger, Sync will own 100% of
    Entrada, and the Parent will own 50% of Sync. In addition, Sync will change
    its name to Entrada Networks, Inc. upon completion of the merger. Throughout
    this proxy statement/prospectus, the term "the combined companies" refers to
    Sync and Entrada following the merger.

Q.  WILL SYNC STOCKHOLDERS RECEIVE ANY SHARES AS A RESULT OF THE MERGER?

A. No. Sync stockholders will continue to hold the Sync shares they currently
    own.

Q.  WHO WILL MANAGE SYNC FOLLOWING THE MERGER?

A. The Chief Executive Officer of Sync following the merger will be Dr. Kanwar
    J.S. Chadha, who is currently the President of Entrada. William K. Guerry,
    currently the Chief Executive Officer, President and Chief Financial Officer
    of Sync, will be the Chief Operating Officer, Chief Financial Officer and
    Vice President-Finance and Administration of Sync following the merger.
    Anand Mehta, currently the Chief Technology Officer and Vice
    President-Engineering of Entrada, will be the Chief Technology Officer and
    Vice President-Engineering of Sync following the merger. Arthur Trakas,
    currently the Executive Vice President-Sales and Marketing of Parent and
    Entrada, will be the Executive Vice President-Sales and Marketing of Sync
    following the merger. Assuming that at the annual meeting the Sync
    stockholders authorize the issuance of Sync common stock under the merger
    agreement and elect the slate of directors that the Sync board of directors
    has nominated,

                                       1
<PAGE>
    Mr. Guerry and William J. Schroeder will step down as directors of Sync and
    the board of directors of Sync following the merger will consist of Gregorio
    Reyes, currently the Chairman of Sync's board of directors, Dr. Chadha,
    Charles A. Haggerty, currently a director of Sync, Leonard N. Hecht,
    currently a director of Parent, and Rohit Phansalkar, currently a director
    of Parent and a partner of Andersen Weinroth & Co. LP, affiliates of which
    own all of the outstanding Series A Preferred Stock of Sync and are
    stockholders of Parent. For more information, see "Other Annual Meeting
    Proposals--Proposal No. 2: Election Of Directors."

Q:  WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A. We are working to complete the merger as quickly as possible. We expect to
    complete the merger by August 31, 2000.

Q:  WHAT ARE THE TAX CONSEQUENCES OF THE MERGER TO SYNC STOCKHOLDERS?

A. The merger will not have any tax consequences for Sync stockholders. For more
    information, see "Material Federal Income Tax Consequences of the Merger."

Q:  WHEN AND WHERE IS THE SYNC STOCKHOLDER MEETING?

A. The annual meeting will take place at       local time, on Monday,
    August 14, 2000, at                         . You may attend the annual
    meeting and vote your shares in person, rather than signing and mailing your
    proxy.

Q.  WHAT DO I NEED TO DO NOW?

A. After carefully reading and considering the information contained in this
    proxy statement/ prospectus, please complete and sign your proxy and return
    it in the enclosed return envelope as soon as possible, so that your shares
    may be represented at the annual meeting. If you sign and send in your proxy
    and do not indicate how you want to vote, we will count your proxy as a vote
    in favor of adoption of the merger agreement. In order to assure that your
    vote is obtained, please vote your proxy as instructed on your proxy card
    even if you currently plan to attend the annual meeting in person.

Q.  DOES SYNC'S BOARD RECOMMEND VOTING IN FAVOR OF THE MERGER?

A. Yes. After careful consideration, the board of directors of Sync unanimously
    recommends voting in favor of authorizing the issuance of shares of Sync
    common stock under the merger agreement.

Q.  ARE THERE RISKS I SHOULD CONSIDER IN DECIDING WHETHER TO VOTE FOR THE
    MERGER?

A. Yes. There are risks and uncertainties because Sync and Entrada are in a
    highly competitive and rapidly evolving industry. In evaluating the merger,
    you should carefully consider these and other factors discussed in the
    section entitled "Risk Factors" on page 15 of this proxy statement/
    prospectus.

Q.  CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

A. Yes. You can change your vote at any time before your proxy is voted at the
    annual meeting. You can do this three different ways. First, you can send a
    written notice stating that you would like to revoke your proxy. Second, you
    can complete and submit a new proxy card. Sync stockholders choosing either
    of these options should send their revocation letter or new proxy card to
    the Sync corporate secretary at the address provided below. The third way
    you may change your vote is to attend the annual meeting and vote in person.
    Simply attending the meeting, however, will not revoke your proxy. If you
    have instructed a broker to vote your shares, you must follow the directions
    provided by your broker to change those instructions.

                                       2
<PAGE>
Q:  IF MY SYNC SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER
    VOTE MY SHARES FOR ME?

A. Your broker will vote your Sync shares only if you provide instructions on
    how to vote. You should follow the directions provided by your broker
    regarding how to instruct your broker to vote your shares. Without
    instructions, your shares will not be voted, unless you appear in person at
    the annual meeting with a legal, valid proxy from the record holder.

Q:  WHO CAN HELP ANSWER MY QUESTIONS?

GENERAL

    SYNC'S BOARD RECOMMENDATION TO STOCKHOLDERS (PAGE 31)

    The Sync board of directors believes that the merger is fair to you and in
your best interest and unanimously recommends that you vote "for" the proposal
to authorize the issuance of Sync common stock under the merger agreement for
completion of the merger. To review the background and reasons for the merger in
greater detail, as well as certain risks related to the merger, see pages 15 and
36.

    OWNERSHIP OF SYNC AND ENTRADA FOLLOWING THE MERGER; STOCK OPTIONS (PAGE 29)

    Immediately following the merger, (i) Sync will own 100% of Entrada, and
(ii) Parent will own 50% of Sync. In addition, certain employees of Entrada will
be granted options to purchase shares of Sync's common stock which, in the
aggregate, shall equal the number of shares of Sync common stock issuable upon
the exercise of all of the outstanding Sync options at the time of the merger.

                                       4
<PAGE>
    REASONS FOR THE MERGER (PAGE 31)

    We believe that the combination of Sync and Entrada will allow Sync to
significantly improve its operating results. In addition the merger represents a
significant business opportunity to enter into the emerging and rapidly growing
market for data storage systems (a.k.a. Storage Area Networks or SANs). Entrada
has already begun the implementation of a strategy for the SAN market and has
SAN products currently in development. We believe that the complementary
technologies, combined resources, expected synergies, experience and market
position of Sync and Entrada, with established relationships with key original
equipment manufacturers and large enterprise customers, create a unique platform
for growth and significant long-term shareholder value.

    In addition, we believe that the merger significantly strengthens our
capabilities by leveraging Parent's past experience in successfully developing
communications technology companies. For example, Parent's networking
system-on-silicon subsidiary, NETsilicon, Inc., was acquired by Parent in 1996
for $5 million. As of May 17, 2000, after Parent helped it develop a new
business model, and after a September 1999 spinoff via an initial public
offering, NETsilicon has a market capitalization of more than $265 million.
Parent's other major subsidiary is Sorrento Networks, which Parent has rebuilt
from a maker of relatively slow-growth video networking products into a pioneer
in the field of all-optical networking products for metropolitan or intra-city
networks, a market with substantial opportunities for growth.

    The merger will strengthen the capabilities of Sync and Entrada to compete
in the very competitive networking market. The combined companies will be able
to (i) provide customers with a more comprehensive set of networking solutions
by expanding each company's product offerings, technologies and customer bases
in the remote access and wide area network areas; (ii) increase each company's
ability to successfully develop products for new high growth technologies and
markets, including storage networking; (iii) increase the overall size and scope
of each company's operations; and (iv) expand each company's distribution
channels. The Sync board of directors believes that the combination with Entrada
will assist Sync in strengthening its ability to effectively compete in the
market and improve the overall financial results of Sync. The Sync board of
directors also believes that the technologies, product lines and fundamental
business and operating strategies of Sync and Entrada are complementary and
consistent, and that Sync and Entrada together can provide a greater range of
products and superior market coverage compared to each as a stand-alone
business. In addition, the Sync board of directors believes that a combination
of the two companies provides greater potential for enhanced stockholder value
than does the continuation of Sync's operations in its present form or any of
the alternative business strategies that it considered.

    APPRAISAL RIGHTS (PAGE 38)

    Holders of Sync common stock are not entitled to dissenters' appraisal
rights under Delaware law in connection with the merger.

    INTERESTS OF SYNC DIRECTORS AND MANAGEMENT IN THE MERGER (PAGE 37)

    In considering the Sync board's recommendation that you vote in favor of the
merger, you should be aware that some officers and directors of Sync have
interests in the merger that are different from, or in addition to, the
interests of Sync stockholders. Please refer to page   for more information.

    MATERIAL FEDERAL INCOME TAX CONSEQUENCES (PAGE 39)

    For United States federal income tax purposes, regardless of whether the
merger will be treated as a reorganization within the meaning of Section 368(a)
of the Internal Revenue Code, no gain or loss will be recognized by Sync or the
Sync stockholders as a result of the merger.

FAIRNESS OPINION OF FINANCIAL ADVISOR (PAGE 32)

    In deciding to approve the issuance of shares of Sync common stock under the
merger, the Sync board of directors considered the opinion, as of the date of
the merger agreement, of its financial advisor, Alliant Partners, as to the
fairness of the exchange ratio in the merger to Sync stockholders from a
financial point of view. This opinion is attached as Annex B to this proxy
statement/prospectus and sets forth assumptions made, matters considered and
limitations on the review undertaken in connection with the opinion. WE
ENCOURAGE STOCKHOLDERS TO READ THIS OPINION CAREFULLY. THIS OPINION IS DIRECTED
TO THE BOARD OF DIRECTORS AND IS NOT A RECOMMENDATION TO STOCKHOLDERS WITH
RESPECT TO ANY MATTER RELATING TO THE MERGER. THE OPINION SPEAKS ONLY AS OF ITS
DATE OF ISSUANCE AND THE FINANCIAL ADVISOR OF SYNC IS UNDER NO OBLIGATION TO
CONFIRM ITS OPINION AS OF A LATER DATE. FURTHER, THE BOARD OF DIRECTORS MAY NOT
NECESSARILY REQUEST THAT ITS FINANCIAL ADVISOR CONFIRM ITS OPINION AS OF A LATER
DATE.

THE SYNC ANNUAL MEETING (PAGE 26)

    The Sync annual meeting will be held at             , at       [a.m./p.m.],
local time, on Monday, August 14, 2000. At the Sync annual meeting, Sync
stockholders will be asked to adopt the merger agreement, as well as to vote
upon other proposals of the board of directors as described in this proxy
statement/prospectus. This proxy statement/prospectus is being furnished to you
in connection with the solicitation by the Sync board of directors of proxies
for use in voting at the annual meeting.

    RECORD DATE; VOTING POWER

    You are entitled to vote at the annual meeting if you owned shares of Sync
as of the close of business on Friday, June 30, 2000, which is the record date.

    On the record date, there were             shares of Sync common stock
entitled to vote at the Sync annual meeting. Sync stockholders will have one
vote for each share of Sync common stock they owned on the record date.

    VOTES REQUIRED

    In order to consummate the merger, a majority of the shares of Sync common
stock present in person or by proxy at the meeting must vote in favor of
adopting the merger agreement. A plurality of votes cast is required to elect
directors. Approval of the amendment to the 1995 Employee Stock Purchase Plan,
as well as approval of Ernst & Young LLP as Sync's independent auditors, require
the affirmative vote of at least a majority of the shares of Sync common stock
present in person or by proxy at the meeting.

    VOTING BY DIRECTORS AND EXECUTIVE OFFICERS

    On the record date, directors and executive officers of Sync and their
affiliates owned and were entitled to vote             shares of Sync common
stock, or approximately   % of the shares of Sync common stock outstanding on
the record date. The directors and executive officers of Sync have indicated
that they intend to vote the Sync common stock owned by them "for" adoption of
the merger agreement.

THE MERGER AND THE MERGER AGREEMENT

    THE MERGER AGREEMENT IS ATTACHED TO THIS PROXY STATEMENT/ PROSPECTUS AS
ANNEX A. WE ENCOURAGE YOU TO READ THE MERGER AGREEMENT CAREFULLY. IT IS THE
PRINCIPAL DOCUMENT GOVERNING THE MERGER.

                                       6
<PAGE>
    MERGER CONSIDERATION (PAGE 39)

    At the closing of the merger, Sync will issue shares of Sync common stock to
Parent in exchange for all of the outstanding common stock of Entrada. The
exchange ratio was determined through arm's-length negotiations between Sync and
Parent. After the merger, Sync will own all of the outstanding common stock of
Entrada, and Parent will own 50% of the outstanding Sync common stock.

    CONDITIONS TO THE COMPLETION OF THE MERGER (PAGE 41)

    The respective obligations of Sync and Parent to effect the merger are
subject to the satisfaction of certain conditions, including, but not limited
to, obtaining requisite Sync stockholder and regulatory approvals, the approval
for quotation on The Nasdaq National Market of the Sync common stock to be
issued pursuant to the merger, the absence of any injunction prohibiting
consummation of the merger, and the accuracy of the representations and
warranties contained in the merger agreement.

    Each of the conditions to the merger may be waived by the company entitled
to assert the condition.

    TERMINATION OF THE MERGER AGREEMENT AND TERMINATION FEE (PAGE 42)

    Sync and Parent can mutually agree to terminate the merger agreement without
completing the merger. Either Sync or Parent can terminate the merger agreement
by written notice if the merger is not completed by August 31, 2000, or if any
court or governmental authority prohibits the transactions contemplated by the
merger agreement and such prohibition is final and nonappealable. Additionally,
if Sync receives a non-solicited proposal from another company to acquire or
merge with Sync that Sync's board of directors considers to be superior to the
proposed transaction with Entrada, then Sync may terminate the merger agreement
upon agreement to pay Parent a termination fee of $1,000,000. Likewise, if
Parent receives a non-solicited proposal from another company to acquire or
merge with Entrada that Parent's board of directors considers to be superior to
the proposed merger with Sync, then Parent may terminate the merger agreement
upon agreement to pay Sync a termination fee of $1,000,000. If the stockholders
of Sync vote not to authorize the issuance of Sync common stock for completion
of the merger, then Sync will be required to pay Parent a fee of $250,000 within
thirty (30) days of such stockholder vote.

    WHEN THE MERGER TAKES EFFECT (PAGE 39)

    The merger will become effective when all necessary documentation has been
filed with the Delaware Secretary of State. Such documentation will be filed
promptly upon satisfaction or waiver of each of the conditions provided in the
merger agreement.

    CONVERSION OF SHARES (PAGE 39)

    After completion of the merger, Parent will no longer have any rights as a
stockholder of Entrada. Once the merger is effective, Parent will surrender its
Entrada stock certificates and in turn will receive Sync stock certificates from
the transfer agent as quickly as is feasible.

    REGULATORY MATTERS (PAGE 40)

    Certain aspects of the merger will require notifications to, and/or
approvals from, certain United States authorities. Sync and Entrada believe that
all material notifications, filings and approvals have been made or obtained, or
will be made or obtained prior to the effective date of the merger, as the case
may be. See "The Merger Agreement--Conditions to the Completion of the Merger."

                                       7
<PAGE>
    ACCOUNTING TREATMENT (PAGE 38)

    The merger will be accounted for as an acquisition of Sync by Entrada under
the "purchase" method of accounting in accordance with generally accepted
accounting principles.

    RESALE OF SYNC COMMON STOCK (PAGE 40)

    All shares of Sync common stock received by Parent in the merger will be
freely transferable, except that Parent shall be deemed to be an "affiliate" (as
such term is defined under the Securities Act) of Sync and, accordingly, such
shares may be resold by Parent only in transactions permitted by the resale
provisions of Rules 144 promulgated under the Securities Act or as otherwise
permitted under the Securities Act.

(1) The pro forma consolidated financial information for Sync and Entrada
    reflects the issuance of 4,231,007 shares of Sync common stock for all of
    the issued and outstanding Entrada shares in connection with the merger and
    reflects the issuance of 700,000 shares of common stock upon the conversion
    of all of Sync's outstanding Series A Preferred Stock, which was issued in
    May 2000 to an affiliate of a stockholder of Parent for net proceeds of
    approximately $2.1 million.

                           COMPARATIVE PER SHARE DATA

    The following table sets forth certain historical per share data of Sync and
Entrada and combined per share data on an unaudited pro forma basis after giving
effect to the merger on a purchase accounting basis assuming 4,231,007 shares of
Sync common stock are issued in the merger in exchange for all of the Entrada
common stock outstanding and reflecting the issuance of 700,000 shares of common
stock upon the conversion of all of the outstanding Series A preferred stock.
The information set forth below should be read in conjunction with the selected
historical consolidated financial data, the unaudited pro forma combined
condensed financial information and the historical financial statements of Sync
and Entrada included in this proxy statement/prospectus. The unaudited pro forma
combined condensed financial information is not necessarily indicative of the
operating results that would have been achieved had the transaction been
effected as of the beginning of the periods presented and should not be
construed as representative of future results of operations. The merger is
expected to be accounted for as a reverse acquisition of Sync by Entrada.
Neither Sync nor Entrada has ever declared or paid cash dividends on its
respective shares of capital stock.

    On April 10, 2000, the last trading day prior to the announcement by Sync
and Entrada that they had reached an agreement concerning the merger, the
closing sales price of Sync common stock as reported on the Nasdaq National
Market was $3.125 per share. The equivalent per share value of Entrada common
stock as of such date was approximately $13,222. On May 12, 2000, the closing
sale price of Sync common stock as reported on the Nasdaq National Market was
$3.50 per share. Based on the May 12, 2000, closing sale price of Sync common
stock, the equivalent per share value of Entrada common stock as of such date
was approximately $14,808.

    As of May 4, 2000, there were 213 stockholders of record of Sync common
stock, and Sync believes there were approximately 2,936 beneficial owners of
Sync common stock.

    Following the merger, Sync common stock will continue to be traded on the
Nasdaq National Market. Sync is in the process of applying for a new trading
symbol to take effect upon the consummation of the merger.

    Neither Sync nor Entrada has ever paid cash dividends on its capital stock.
Any future determination to pay cash dividends will be at the discretion of the
board of directors and will be dependent upon the combined companies' financial
condition, results of operations, capital requirements and such other factors as
the board of directors deems relevant.

                                  RISK FACTORS

    IN ADDITION TO THE OTHER INFORMATION CONTAINED OR INCORPORATED BY REFERENCE
IN THIS PROXY STATEMENT/ PROSPECTUS, SYNC STOCKHOLDERS SHOULD CAREFULLY CONSIDER
THE FOLLOWING RISK FACTORS IN DECIDING WHETHER TO VOTE FOR THE MERGER. THE
OCCURRENCE OF ANY OF THE RISKS DESCRIBED BELOW OR INCORPORATED BY REFERENCE
HEREIN COULD MATERIALLY ADVERSELY AFFECT THE BUSINESS, FINANCIAL CONDITION AND
RESULTS OF OPERATION OF SYNC.

RISKS RELATED TO THE MERGER

    SYNC AND ENTRADA MAY BE UNABLE TO SUCCESSFULLY INTEGRATE THEIR OPERATIONS
AND REALIZE THE COST SAVINGS THAT WE ANTICIPATE.

    The success of the merger depends in substantial part on the ability of Sync
and Entrada to integrate their respective operations in an efficient and
effective manner. The integration of Entrada's operations into Sync following
the merger will require the dedication of management resources in order to
achieve the anticipated operating efficiencies of the merger which may
temporarily distract attention from day to day business operations of the
combined companies. The difficulties of combining the Entrada operations into
Sync are exacerbated by the necessity of coordinating geographically separated
organizations, integrating personnel with disparate business backgrounds and
combining different corporate cultures. No assurance can be given that
difficulties encountered in integrating the operations of Entrada into Sync will
be overcome or that the benefits expected from such integration will be
realized. The inability of management to successfully integrate the operations
of the two companies could have a material adverse effect on the business,
results of operations and financial condition of the combined companies. In
addition, as commonly occurs with mergers of technology companies, aggressive
competitors may undertake initiatives to attract customers and to recruit key
employees, which could have a material adverse effect on the business, results
of operations and financial condition of Sync.

    THE COMBINED COMPANIES WILL INCUR SUBSTANTIAL EXPENSES AND RESTRUCTURING
CHARGES IN CONNECTION WITH THE MERGER.

    Sync and Entrada expect to incur certain expenses in connection with the
restructuring and consolidation of the operations of the combined companies
including, but not limited to, costs related to the closure and elimination of
duplicate leased facilities and write-offs of related fixed assets, write-offs
of discontinued products, and severance costs. Sync and Entrada anticipate that
the integration activities will ultimately result in increased efficiencies and
lower operating costs. These activities have not been formalized, and therefore
the expenses and related efficiency cost savings are not currently estimable
with a reasonable degree of accuracy. Although Sync and Entrada expect that the
elimination of duplicative expenses as well as other efficiencies related to the
integration of the businesses may offset additional expenses over time, there
can be no assurance that such net benefit will be achieved in the near term, or
at all.

    Parent expects to incur direct transaction costs of approximately $200,000
consisting primarily of legal and accounting costs. These direct costs have been
included in the estimated purchase price reflected in the pro forma condensed
consolidated balance sheet.

    Sync estimates it will incur direct transaction costs of approximately
$700,000 associated with the merger, consisting primarily of fees for investment
banking, filings with regulatory agencies, legal, accounting, financial printing
and other related costs. These transaction costs will be expensed as they are
incurred by Sync and have been reflected in the pro forma condensed consolidated
balance sheet.

                                       15
<PAGE>
    THE MERGER MAY ADVERSELY IMPACT THE BUYING PATTERNS OF THE CUSTOMERS OF THE
COMBINED COMPANIES.

    There is no assurance that resellers and current and potential end-users of
Sync and Entrada products will continue their current buying patterns without
regard to the announced merger. Certain customers may defer purchasing decisions
as they evaluate the combined companies' future product strategy and consider
product offerings of competitors. If substantial numbers of customers decide to
defer or cancel such purchases, such deferrals or cancellations could have a
material adverse effect on the business, results of operations and financial
condition of the combined companies.

    SYNC AND ENTRADA MAY NOT BE ABLE TO OBTAIN THIRD PARTY CONSENTS IN
CONNECTION WITH THE MERGER.

    Sync and Entrada each have contracts with many suppliers, customers and
other business partners relating to, among other things, certain intellectual
property rights. Some of these contracts require Sync and Entrada to obtain the
consent, waiver or approval of these other parties in connection with the
merger. If consent, waiver or approval cannot be obtained, Sync and Entrada may
lose the right to use intellectual property that is necessary for their
respective businesses. Sync and Entrada have agreed to use commercially
reasonable efforts to secure the necessary consents, waivers and approvals.
However, Sync and Entrada may not be able to obtain all of the necessary
consents, waivers and approvals, which could have a material adverse effect on
the business, results of operations and financial condition of the combined
companies.

    OBTAINING REQUIRED GOVERNMENT APPROVALS AND SATISFYING CLOSING CONDITIONS
MAY DELAY OR PREVENT COMPLETION OF THE MERGER.

    Completion of the merger is conditioned upon the receipt of all material
governmental authorizations, consents, orders and approvals, including the
expiration or termination of the applicable waiting periods, and any extension
of the waiting periods, under the Hart-Scott-Rodino Antitrust Improvements Act
of 1976, as amended. Sync and Entrada intend to vigorously pursue all required
approvals. The requirement for these approvals could delay the completion of the
merger for a significant period of time after Sync stockholders have approved
the proposals relating to the merger at the annual meeting. No assurance can be
given, however, that these approvals will be obtained or that the required
conditions to closing will be satisfied and, if all such approvals are obtained
and the conditions are satisfied, no assurance can be given as to the terms,
conditions and timing thereof.

    SYNC'S OFFICERS AND DIRECTORS HAVE CONFLICTS OF INTEREST THAT MAY INFLUENCE
THEM TO SUPPORT THE MERGER.

    The directors and officers of Sync have certain interests in the merger and
participate in certain arrangements that are different from, or are in addition
to those of Sync stockholders generally. These interests and arrangements
include:

    - all executive officers of Sync are parties to agreements that provide for
      the partial vesting of any unvested options upon a change in control and
      certain severance benefits if such executive officer is terminated
      following a corporate transaction such as the merger

    - Mr. Gregorio Reyes, the current Chairman of the Sync board of directors,
      will remain as a director of Sync following the merger, and certain
      current executive officers of Sync will remain as executives of Sync
      following the merger

    - Mr. Reyes is party to an agreement that provides for the full vesting of
      any unvested options upon a change in control and certain severance
      benefits if he is terminated following a corporate transaction such as the
      merger.

                                       16
<PAGE>
    THE VALUE OF SYNC STOCKHOLDERS' HOLDINGS IN SYNC MAY BE DIMINISHED AS A
RESULT OF THE MERGER.

    Although the companies believe that beneficial synergies will result from
the merger, there can be no assurance that the combining of the two companies'
businesses, even if achieved in an efficient, effective and timely manner, will
result in combined results of operations and financial condition superior to
what would have been achieved by each company independently, or as to the period
of time required to achieve such result. The issuance of Sync common stock in
connection with the merger may have the effect of reducing Sync's net income per
share from levels otherwise expected and could reduce the market price of the
Sync common stock unless revenue growth or cost savings and other business
synergies sufficient to offset the effect of such issuance can be achieved. As a
consequence of the merger, Sync stockholders will lose the chance to invest in
the development and exploitation of Sync's products on a stand-alone basis.
Additionally, Sync following the merger will have different management than
Sync's current management, and consequently the management of Sync following the
merger may make strategic and operational decisions that differ from those of
Sync's current management.

    THE NUMBER OF SYNC SHARES OF COMMON STOCK THAT ARE TO BE EXCHANGED FOR ALL
OF THE SHARES OF ENTRADA COMMON STOCK IS FIXED.

    Under the terms of the merger agreement, the outstanding shares of Entrada
common stock issued and outstanding at the closing will be converted into the
right to receive shares of Sync common stock. The merger agreement does not
contain any provisions for adjustment of the exchange amount or termination of
the merger agreement based solely on fluctuations in the price of Sync common
stock. The price of Sync common stock at the closing of the merger may vary from
its prices on the date of this proxy statement/prospectus and on the date of the
annual meeting. These prices may vary because of changes in the business,
operations or prospects of Sync, market assessments of the likelihood that the
merger will be completed, the timing of the completion of the merger, the
prospects of post-merger operations, regulatory considerations, general market
and economic conditions and other factors. Because the date that the merger is
completed will be later than the date of the annual meeting, the price of Sync
common stock on the date of the annual meeting may not be indicative of its
price on the date the merger is completed. We urge Sync stockholders to obtain
current market quotations for Sync common stock.

    SYNC CANNOT ASSURE YOU THAT ITS STOCK PRICE WILL NOT DECLINE AFTER THE
MERGER.

    Factors such as announcements of technological innovations or the
introduction of new products by the combined companies or their competitors, as
well as market conditions in the technology sector, may have a significant
effect on the market price of Sync's common stock following the merger. Further,
the stock market has experienced volatility which has particularly affected the
market prices of equity securities of many high technology companies and which
often has been unrelated to the operating performance of such companies. These
market fluctuations may have an adverse effect on the price of Sync's common
stock following the merger.

    THE COMBINED COMPANIES MAY FACE INCREASED CREDIT RISKS AS A RESULT OF THE
MERGER.

    Entrada distributes a significant portion of its products through third
party distributors, resellers and original equipment manufacturers ("OEMs"). Due
to the consolidation in the distribution and reseller channels and Entrada's
reliance upon these channels, Entrada has experienced an increased concentration
of credit risks. While Sync and Entrada have each continuously monitored and
managed these risks, financial difficulties on the part of one or more of their
respective significant distributors, resellers or OEM partners may have a
material adverse effect on the combined companies.

                                       17

RISKS RELATED TO THE COMBINED COMPANIES' BUSINESS

    SYNC AND ENTRADA HAVE INCURRED CONSISTENT OPERATING LOSSES AND THE COMBINED
COMPANIES MAY CONTINUE TO INCUR SIGNIFICANT NET LOSSES AND NEGATIVE CASH FLOWS
IN THE FUTURE, AND THE COMBINED COMPANIES MAY NEVER BE PROFITABLE.

    Sync has experienced operating losses since inception and has never been
profitable. In recent years, Sync has experienced operating losses of
$18.0 million in 1997, $16.3 million in 1998 and $4.7 million in 1999. As of
December 31, 1999, Sync had an accumulated deficit of approximately
$58.7 million. Entrada experienced operating losses of $6.4 million in fiscal
1998, $3.1 million in fiscal 1999 and $2.8 million in fiscal 2000, and has not
achieved operating profitability. As of January 31, 2000, Entrada had an
accumulated deficit of approximately $20.5 million. Both Sync and Entrada have
experienced, and may in the future experience, significant fluctuations in
revenues and operating results from quarter to quarter and from year to year due
to a combination of factors. Factors that have caused, or may cause, revenues
and operating results to vary significantly from period to period include:

    - the timing of significant orders;

    - the relatively long length of the sales cycles for certain products;

    - the market conditions, competition and pricing in the networking industry;

    - the timing of capital expenditures by target market customers;

    - the success in developing, introducing and shipping new products;

    - new product introductions by competitors;

    - production or quality problems;

    - changes in material costs;

    - disruption in sources of supply;

    - changes in foreign currency exchange rates; and

    - general economic conditions.

    In addition, revenues and gross margins may fluctuate due to the mix of
distribution channels employed and the mix of products sold. For example, Sync
generally realizes a higher gross margin on direct sales than on sales through
its channel partners and other resellers. Accordingly, if channel partners and
other resellers account for a large percentage of the combined companies' net
revenues, gross profit as a percentage of net revenues may decline.

    The combined companies' future revenues are difficult to predict. Revenues
and operating results in any quarter depend on the volume and timing of, and the
ability to fulfill, orders received within the quarter. Sales of many of Sync's
and Entrada's products typically involve a sales cycle of several months or over
a year from the point of initial customer contact until receipt of the first
system order, and, in addition, Sync and Entrada have in the past encountered,
and may in the future encounter, delays between initial orders and network-wide
deployment. There can be no assurance that average sales cycles will not
increase in future periods. Significant portions of the combined companies'
expenses are relatively fixed. If sales are below expectations in any given
period, the adverse effect of a shortfall in sales on the combined companies'
operating results may be magnified by their inability to adjust spending to
compensate for such shortfall. Sync and Entrada have in the past and may in the
future reduce prices or increase spending to respond to competition or to pursue
new product or market opportunities. Accordingly, there can be no assurance that
the combined companies will be able to attain or sustain profitability on a
quarterly or an annual basis. In addition, if the combined companies'

                                       18
<PAGE>
operating results fall below the expectations of public market analysts and
investors, the price of the Sync's common stock would likely be materially and
adversely affected.

    IF THE COMBINED COMPANIES FAIL TO MANAGE EXPANSION EFFECTIVELY, THEY MAY NOT
BE ABLE TO SUCCESSFULLY MANAGE THEIR BUSINESS, WHICH COULD CAUSE THE COMBINED
COMPANIES TO FAIL TO MEET CUSTOMER DEMAND OR TO ATTRACT NEW CUSTOMERS.

    Neither Sync nor Entrada has had significant experience in managing issues
related to the expansion of their respective operations, which may place
significant demands on the combined companies' administrative, operational and
financial resources. To manage future growth, if any, the combined companies
must:

    - implement additional management information systems

    - improve their operating, administrative, financial and accounting systems,
      procedures and controls

    - attract, train and retain new employees

    - maintain close coordination among their executive, engineering,
      professional services, accounting, finance, marketing, sales and
      operations organizations.

    There can be no assurance that the combined companies will be able to
perform such actions successfully. The combined companies intend to continue to
invest in improving their financial systems and controls in connection with
higher levels of operations. In the future, the combined companies may make
additional acquisitions of complementary companies, products or technologies.
Managing acquired businesses entails numerous operational and financial risks,
including difficulties in assimilating acquired operations, diversion of
management's attention to other business concerns, amortization of acquired
intangible assets and potential loss of key employees or customers of acquired
operations. There can be no assurance that the combined companies will be able
to effectively achieve growth, or manage any such growth, and failure to do so
could have a material adverse effect on the combined companies' operating
results.

    THE COMBINED COMPANIES WILL DEPEND ON THIRD PARTY LICENSES FOR THEIR
PRODUCTS.

    Sync and Entrada rely on certain software technology which is licensed from
third parties and used in Sync's and Entrada's products to perform key functions
and provide additional functionality. Because the combined companies' products
will incorporate software developed and maintained by third parties, the
combined companies will be, to a certain extent, dependent upon such third
parties' ability to maintain or enhance their current products, to develop new
products on a timely and cost-effective basis, and to respond to emerging
industry standards and other technological changes. Further, these third-party
technology licenses may not always be available to the combined companies on
commercially reasonable terms or at all. If the combined companies' agreements
with third-party vendors are not renewed or the third-party software fails to
address the needs of the combined companies' software products, the combined
companies would be required to find alternative software products or
technologies of equal performance or functionality. Sync and Entrada cannot
assure that they would be able to replace the functionality provided by
third-party software if the combined companies lost the license to this
software, if it became obsolete or incompatible with future versions of the
combined companies' products, or if the software otherwise was not adequately
maintained or updated.

                                       19
<PAGE>
    THE COMBINED COMPANIES WILL DEPEND ON CONTINUED DEMAND FOR THEIR PRODUCTS BY
ORIGINAL EQUIPMENT MANUFACTURERS AND OTHER RESELLERS.

    Sync and Entrada have OEM relationships with a number of companies that
provide network access hardware. Agreements with OEM customers provide for
Sync's and Entrada's software products to be bundled with the OEM's hardware
products when sold. The cost, if any, of integrating software is assumed by the
OEM. These agreements may provide for a license fee to be paid to Sync or
Entrada. The license fee may be a royalty based upon unit sales, a flat fee or a
fee for a certain time period. Sync and Entrada cannot assure you that OEM
customers will accurately report license fees or have the ability to pay them.
Each of the combined companies' distributors and resellers will be able to cease
marketing the combined companies' products with limited notice and with little
or no penalty. Other risks include whether the OEMs will:

    - give sufficient priority to marketing the combined companies' products

    - continue to offer the combined companies' products at all

    - elect instead to bundle software products of the combined
      companies'competitors.

In 1999, 1998 and 1997, OEM revenue represented approximately 6%, 19% and 25%,
respectively, of Sync's total net revenue. In fiscal 2000, 1999 and 1998, OEM
revenue represented approximately 46%, 26% and 21%, respectively, of Entrada's
total net revenue. In the past several years, Sync has seen a significant
reduction in revenue from certain OEM customers and the combined companies may
not be able to replace the revenue generated from those relationships.

    THE COMBINED COMPANIES WILL RELY ON THIRD PARTY MANUFACTURERS TO PRODUCE
THEIR PRODUCTS, AND THEIR REPUTATION AND RESULTS OF OPERATIONS COULD BE
ADVERSELY AFFECTED BY THE COMBINED COMPANIES INABILITY TO CONTROL THEIR
OPERATIONS.

    The combined companies' manufacturing operations will consist primarily of
materials planning and procurement, light assembly, system integration, testing
and quality assurance. Sync and Entrada have entered into arrangements with
contract manufacturers to outsource substantial portions of their respective
board level procurement, assembly and system test operations, and Sync and
Entrada expect to expand the use of such outsource arrangements in the future.
The combined companies' reliance on third party manufacturers will expose them
to the following risks outside their control:

    - unexpected increases in manufacturing costs;

    - interruptions in shipments if any manufacturer is unable to complete
      production;

    - inability to control quality of finished products;

    - inability to control delivery schedules;

    - unpredictability of manufacturing yield;

    - potential lack of adequate capacity; and

    - potential inability to secure adequate volumes of components.

    The inability of the combined companies' contract manufacturers to provide
the combined companies with adequate supplies of high quality products could
have a material adverse effect upon the combined companies' business, operating
results and financial condition. The loss of any of the combined companies'
contract manufacturers could cause a delay in the combined companies' ability to
fulfill orders while the combined companies identify a replacement manufacturer.
Such an event could have a material adverse effect on the combined companies'
business, operating results and financial condition.

                                       20
<PAGE>
    The combined companies' manufacturing procedures may in certain instances
create a risk of excess or inadequate inventory if orders do not match
forecasts. Any manufacturing delays, excess manufacturing capacity or
inventories or inability to increase manufacturing capacity, if required, could
have a material adverse effect on the combined companies' business, operating
results and financial condition.

    THE COMBINED COMPANIES WILL BE DEPENDENT ON SUPPLIERS, MANY OF WHICH WILL BE
THE SOLE SOURCE FOR THEIR COMPONENTS, AND THEIR PRODUCTION WOULD BE SERIOUSLY
HARMED IF THESE SUPPLIERS ARE NOT ABLE TO MEET THE COMBINED COMPANIES' DEMAND
AND ALTERNATIVE SOURCES ARE NOT AVAILABLE.

    Certain key components used in the manufacture of Sync's and Entrada's
products are currently purchased only from single or limited sources. At
present, single-sourced components include programmable integrated circuits,
selected other integrated circuits and cables, custom-molded plastics and
custom-tooled sheet metal, and limited-sourced components include flash
memories, printed circuit boards and selected integrated circuits. Sync and
Entrada generally rely upon contract manufacturers to buy component parts that
are incorporated into board assemblies. Sync and Entrada each directly buys
final assembly parts, such as plastics and metal covers, cables and other parts
used in final configurations. The combined companies generally will not have
long-term agreements with any of these single or limited sources of supply. Any
loss of a supplier, increase in lead times, cost increases, component supply
interruption, or the inability of the combined companies to procure these
components from alternate sources at acceptable prices and within a reasonable
time, could have a material adverse effect upon the combined companies'
business, operating results and financial condition. If orders do not match
forecasts, the combined companies may have excess or inadequate inventory of
certain materials and components, and suppliers may demand longer lead times,
higher prices or termination of contracts. From time to time Sync and Entrada
have experienced shortages of certain components and have paid above-market
prices to acquire such components on an accelerated basis or have experienced
delays in fulfilling orders while waiting to obtain the necessary components.
Such shortages may occur in the future and could have a material adverse effect
on the combined companies' business, operating results and financial condition.

    THE COMBINED COMPANIES WILL HAVE POTENTIAL SEVERANCE PAYMENT LIABILITIES.

    Sync's executive officers have entered into employment agreements under
which such persons will be entitled to receive severance payments in certain
circumstances, including following any termination of their employment within
one year following a "change in control" of Sync, including the change in
control that will be deemed to result from the consummation of the merger.
Assuming the termination of the employment of all of the Sync executive officers
immediately following the consummation of the merger, the combined companies'
aggregate liabilities under such severance provisions could be as much as
approximately $800,000. Due to the nature of these termination rights, some or
all of these severance payments may not be includable in the merger reserve and,
therefore, could adversely impact earnings in any subsequent quarters in which
the rights are exercised.

    THERE IS NO ASSURANCE THAT SYNC WILL CONTINUE TO MEET THE REQUIREMENTS FOR
CONTINUED LISTING ON THE NASDAQ NATIONAL MARKET.

    Sync's common stock is listed and traded on the Nasdaq National Market. On
January 4, 1999, Sync received a letter from Nasdaq notifying it of its failure
to maintain a closing bid price of greater than $1.00 in accordance with the
Nasdaq listing requirements. In order to comply with the Nasdaq listing
requirements, Sync implemented a 1 for 5 reverse stock split on June 28, 1999.
As a result of the reverse stock split, Sync maintained its stock price above
the $1 per share minimum level, and accordingly, was informed by Nasdaq that it
had met the requirements for continued listing. However,

                                       21
<PAGE>
there can be no assurance that Sync will meet the minimum closing bid price or
any other Nasdaq listing requirements on an ongoing basis.

    SYNC'S AND ENTRADA'S CHARTER DOCUMENTS, AND CERTAIN BENEFIT PLANS AND OTHER
AGREEMENTS, WILL CONTAIN ANTI-TAKEOVER PROVISIONS.

    Sync and Entrada are currently, and following the merger will continue to
be, subject to the provisions of Section 203 of the Delaware General Corporation
Law, an anti-takeover law. In addition, certain provisions of Sync's and
Entrada's charter documents, including provisions eliminating cumulative voting,
eliminating the ability of stockholders to call meetings or to take actions by
written consent and limiting the ability of stockholders to raise matters at a
meeting of stockholders without giving advance notice, may have the effect of
delaying or preventing a change in control or management of Sync and Entrada,
which could have an adverse effect on the market price of Sync's common stock.
Certain of Sync's and Entrada's stock option and purchase plans and agreements
will provide for assumption of such plans, or, alternatively, immediate vesting
upon a change of control or similar event. In addition, Sync and Entrada have
entered into severance agreements with their respective officers, pursuant to
which such officers are entitled to defined severance payments if they are
actually or constructively terminated within specified time periods following a
change of control. The board of directors of Sync currently has, and following
the merger will continue to have, authority to issue up to 2,000,000 shares of
preferred stock and to fix the rights, preferences, privileges and restrictions,
including voting rights, of these shares without any further vote or action by
the stockholders. The rights of the holders of the common stock will be subject
to, and may be adversely affected by, the rights of the holders of any preferred
stock that may be issued in the future. The issuance of preferred stock, while
providing desirable flexibility in connection with possible acquisitions and
other corporate purposes, could have the effect of making it more difficult for
a third party to acquire a majority of the outstanding voting stock of Sync and
Entrada, thereby delaying, deferring or preventing a change in control.
Furthermore, such preferred stock may have other rights, including economic
rights senior to the common stock, and as a result, the issuance of such
preferred stock could have a material adverse effect on the market value of the
common stock. Sync and Entrada have no present plan to issue shares of preferred
stock.

RISKS RELATED TO THE COMBINED COMPANIES' INDUSTRY

    THE NETWORK ACCESS MARKET IS HIGHLY COMPETITIVE, AND THE COMBINED COMPANIES
WILL FACE RISKS ASSOCIATED WITH RAPIDLY CHANGING TECHNOLOGY, EVOLVING INDUSTRY
STANDARDS AND FREQUENT NEW PRODUCT INTRODUCTIONS.

    The market for communications products is intensely competitive and subject
to rapid technological change and emerging industry standards, with frequent new
product introductions and enhancements, and constant pressure to reduce prices.
Increased competition may force us to lower our prices, experience decreased
gross margins or lose market acceptance. Sync believes that the principal
competitive factors in the combined companies' market include:

    - expertise and familiarity with systems network architecture (SNA) networks
      and protocols

    - expertise and knowledge with mission-critical network solutions

    - product performance, features, functionality and reliability

    - price and overall cost of ownership

    - timeliness of new product introductions

    - adoption of emerging industry standards

    - service and support.

                                       22

Corporation, Performance Technologies Incorporated, Pika Technologies Inc., SDL
Communications, Inc. and others. In the remote access area, Entrada competes
with Lucent Technologies, Inc. Cisco Systems, Inc. 3Com Corporation, LM Ericsson
Telephone Company, Intel Corporation, Nbase-Xyplex, Nortel Networks Corp. Hlgd.,
Perle Systems Limited, General DataComm Inds. Inc., Cabletron Systems, Inc.,
Assured Access Technologies, Inc. and others. Potential competitors of the
combined companies include other internetworking and WAN access and transmission
companies, frame relay switch providers, and the combined companies' channel
partners.

    The combined companies face the following challenges from their competitors:

    - Certain of these competitors have announced products and intentions to
      enter the frame relay access or circuit management market

    - Many of these current and potential competitors have longer operating
      histories and greater financial, technical, sales, marketing and other
      resources, as well as greater name recognition and a larger customer base

    - Certain of these competitors may be able to respond more quickly to new or
      emerging technologies and changes in customer requirements or may be able
      to devote greater resources to the development, promotion, sale and
      support of their products

    - Many of these competitors have long-standing customer relationships with
      large enterprises that are part of the combined companies' target market,
      and these relationships may make it more difficult to complete sales of
      the combined companies' products to these enterprises

    - Certain of Sync's channel partners have in the past developed competitive
      products and terminated their relationships with Sync, and such
      developments could occur in the future with respect to the combined
      companies.

    As a consequence of all these factors, the combined companies may face
increased competition, particularly in the frame relay market. Increased
competition could result in significant price competition, reduced profit
margins or loss of market share, any of which could have a material adverse
effect on the combined companies' business, operating results and financial
condition. There can be no assurance that the combined companies will be able to
compete successfully in the future.

    THE COMBINED COMPANIES WILL DEPEND ON KEY PERSONNEL AND WILL FACE RISKS
ASSOCIATED WITH THE HIRING, RETENTION AND INTEGRATION OF SUFFICIENT QUALIFIED
PERSONNEL.

    The success of the combined companies after the merger depends in part upon
the retention of key employees of Sync and Entrada. In addition, the combined
companies' future success also depends in large part upon their ability to
attract highly skilled engineering, managerial, sales and marketing personnel.
Competition for qualified personnel in the networking industry is very intense,
especially

                                       23
<PAGE>
with respect to sales and engineering personnel. Stock options, which generally
become exercisable only over a period of several years of employment, serve as
an important incentive for retaining key employees. The stock options held by
most Entrada optionees will terminate. Sync intends to issue options to purchase
Sync common stock to these optionees. During 1999, Sync and Entrada encountered
significant personnel turnover in research and development, sales and other
functional areas and experienced significant turnover in the composition of its
executive officers. Such turnover has affected its ability to successfully
develop new products and generate additional business. The loss of the services
of any of key personnel or the failure to attract or retain qualified personnel
in the future could have a material adverse effect on the combined companies'
business, operating results or financial condition.

    IF THIRD PARTIES INFRINGE THE COMBINED COMPANIES' INTELLECTUAL PROPERTY AND
PROPRIETARY TECHNOLOGY, THE COMBINED COMPANIES MAY EXPEND SIGNIFICANT RESOURCES
ENFORCING THEIR RIGHTS OR SUFFER COMPETITIVE INJURY.

    The combined companies' future success depends, in part, upon their
proprietary technology. Sync does not hold any patents and currently relies on a
combination of contractual rights, trade secrets and copyright laws to establish
and protect its proprietary rights on its products. Entrada owns approximately
nine patents, but such patents are not anticipated to be material to the
business of the combined companies. There can be no assurance that the steps
taken by the combined companies to protect their intellectual property will be
adequate to prevent misappropriation of their technology or that their
competitors will not independently develop technologies that are substantially
equivalent or superior to combined companies' technology. In the event that
protective measures are not successful, combined companies' business, operating
results and financial condition could be materially and adversely affected. In
addition, the laws of some foreign countries will not protect the combined
companies' proprietary rights to the same extent as do the laws of the United
States.

    THIRD PARTIES MAY CLAIM IN THE FUTURE THAT THE COMBINED COMPANIES ARE
INFRINGING THE INTELLECTUAL PROPERTY OF SUCH THIRD PARTIES, AND THE COMBINED
COMPANIES COULD SUFFER SIGNIFICANT LITIGATION OR LICENSING EXPENSES OR BE
PREVENTED FROM SELLING PRODUCTS IF ANY SUCH CLAIMS ARE SUCCESSFUL.

    The combined companies will be subject to the risk of adverse claims and
litigation alleging infringement of intellectual property rights of others.
There can be no assurance that third parties will not assert infringement claims
in the future with respect to Sync's and Entrada's current or future products or
that any such claims will not require the combined companies to enter into
license arrangements or result in litigation, regardless of the merits of such
claims. No assurance can be given that any necessary licenses will be available
or that, if available, such licenses can be obtained on commercially reasonable
terms. Should litigation with respect to any such claims commence, such
litigation could be expensive and time-consuming and could have a material
adverse effect on the combined companies' business, operating results and
financial condition regardless of the outcome of such litigation.

    PRODUCT DEFECTS MAY HARM THE COMBINED COMPANIES' BUSINESS.

    Products as complex as those to be offered by the combined companies may
contain undetected software or hardware errors. Such errors have occurred in the
past with respect to products offered by Sync and Entrada, and there can be no
assurance that, despite testing by the combined companies and customers, errors
will not be found after commencement of commercial shipments. Moreover, there
can be no assurance that once detected, such errors can be corrected in a timely
manner, if at all. Software errors may take several months to correct, if they
can be corrected at all, and hardware errors may take even longer to rectify.
The occurrence of such software or hardware errors, as well as any delay in
correcting them, could result in the delay or loss of market acceptance of the
combined

                                       24
<PAGE>
companies' products, additional warranty expense, diversion of engineering and
other resources from the combined companies' product development efforts or the
loss of credibility with the combined companies' end-user customers, channel
partners and other resellers, any of which could have a material adverse effect
on the combined companies' business, operating results and financial condition.

    THE COMBINED COMPANIES MAY FACE RISKS ASSOCIATED WITH THE CONSOLIDATION OF
THE NETWORK ACCESS BUSINESS INDUSTRY.

    Certain of Sync's and Entrada's major competitors have been engaged in
merger and acquisition transactions. Such consolidations by competitors are
likely to create entities with increased market shares, customer bases,
technology and marketing expertise, sales force size, or proprietary technology
in product markets in which the combined companies will compete. These
developments may adversely affect the combined companies' ability to compete.

    THE COMBINED COMPANIES' FINANCIAL CONDITION MAY BE ADVERSELY IMPACTED BY A
DECLINE IN GENERAL ECONOMIC CONDITIONS.

    Demand for the combined companies' products will depend in large part on the
overall demand for communications and networking products, which has in the past
and may in the future fluctuate significantly based on numerous factors,
including capital spending levels and general economic conditions. There can be
no assurance that the combined companies will not experience a decline in demand
for their products due to general economic conditions. Any such decline could
have a material adverse effect on the combined companies' business, operating
results and financial condition.

    THE COMBINED COMPANIES MAY FACE RISKS ASSOCIATED WITH TARIFF AND REGULATORY
MATTERS.

    Rates for public telecommunications services, including features and
capacity of such services, are governed by tariffs determined by carriers and
subject to regulatory approval. Future changes in these tariffs could have a
material adverse effect on the combined companies' business. For example, should
tariffs for frame relay services increase relative to tariffs for dedicated
leased lines, the cost-effectiveness of the combined companies' products could
be reduced, which could have a material adverse effect on the combined
companies' business, operating results and financial condition. In addition, the
combined companies' products must meet industry standards and receive
certification for connection to certain public telecommunications networks prior
to their sale. In the United States, the combined companies' products must
comply with various regulations defined by the Federal Communications Commission
and Underwriters Laboratories. Internationally, the combined companies' products
must comply with standards established by the various European Community
telecommunications authorities. In addition, carriers require that equipment
connected to their networks comply with their own standards. Any future
inability to obtain on a timely basis or retain domestic or foreign regulatory
approvals or certifications or to comply with existing or evolving industry
standards could have a material adverse effect on the combined companies'
business, operating results and financial condition.

                            THE SYNC ANNUAL MEETING

    We are furnishing this proxy statement/prospectus to stockholders of Sync as
part of the solicitation of proxies by the Sync board of directors for use at
the annual meeting.

DATE, TIME AND PLACE

    The Sync annual meeting will be held at             , at       [a.m./p.m.],
local time, on Monday, August 14, 2000.

PURPOSE OF ANNUAL MEETING

    At the Sync annual meeting, we are asking holders of Sync common stock to
adopt the following proposals:

        1.  To authorize the issuance of shares of Sync common stock under the
    merger agreement for completion of the merger. The Sync board of directors
    has determined that the merger is fair to, and in the best interests of,
    Sync stockholders, has approved the merger and the issuance of shares of
    Sync common stock under the merger agreement, and recommends that Sync
    stockholders vote "for" authorization of the issuance of shares of Sync
    common stock under the merger agreement;

        2.  To elect directors to serve for the ensuing year and until their
    successors are elected and qualified;

        3.  To amend the 1995 Employee Stock Purchase Plan to increase the
    number of shares reserved for issuance thereunder by an additional 100,000
    shares;

        4.  To ratify the appointment of Ernst & Young LLP as Sync's independent
    auditors for the fiscal year ending December 31, 2000; and

        5.  To transact such other business as may properly be brought before
    the annual meeting or any postponements or adjournments of it by the Sync
    board of directors.

RECORD DATE; VOTING POWER; QUORUM

    Only holders of record of Sync common stock at the close of business on
Friday, June 30, 2000, the record date, are entitled to notice of and to vote at
the annual meeting. On the record date,             shares of Sync common stock
were issued and outstanding. Sync stockholders will have one vote for each share
of Sync common stock they owned on the record date. A quorum is present at the
annual meeting if a majority of the shares of Sync common stock issued and
outstanding and entitled to vote on the record date are represented in person or
by proxy. For purposes of the quorum and the discussion below under "Votes
Required" regarding the vote necessary to adopt each stockholder proposal,
stockholders of record who are present at the meeting in person or by proxy and
who abstain, including brokers holding customers' shares of record who cause
abstentions to be recorded at the meeting, are considered stockholders who are
present and entitled to vote and they count toward the quorum. In the event that
a quorum is not present at the annual meeting, it is expected that the meeting
will be adjourned or postponed to solicit additional proxies. Holders of record
of Sync common stock on the record date are entitled to one vote per share at
the annual meeting for each of the proposals to be voted on.

    Brokers holding shares of record for customers generally are not entitled to
vote on certain matters unless they receive voting instructions from their
customers. As used in this proxy statement/ prospectus, "uninstructed shares"
means shares held by a broker who has not received instructions from its
customers on such matters and the broker has so notified Sync on a proxy form in
accordance with industry practice or has otherwise advised Sync that it lacks
voting authority. As used in this proxy

                                       26
<PAGE>
statement/prospectus, "broker non-votes" means the votes that could have been
cast on the matter in question by brokers with respect to uninstructed shares if
the brokers had received their customers' instructions.

VOTES REQUIRED

    Approval of the proposal to authorize the issuance of Sync common stock for
completion of the merger requires the affirmative vote of at least a majority of
the shares present in person or by proxy at the meeting and entitled to vote.
Uninstructed shares may not be voted on this matter, and therefore broker
non-votes do not affect the outcome. Abstentions have the effect of negative
votes.

    Directors are elected by a plurality and the four (4) nominees who receive
the most votes will be elected. Abstentions and broker non-votes will not be
taken into account in determining the outcome of the election.

    Approval of the amendment to the 1995 Employee Stock Purchase Plan requires
the affirmative vote of at least a majority of the shares present in person or
by proxy at the meeting and entitled to vote. Uninstructed shares are entitled
to vote on this matter. Therefore, abstentions and broker non-votes have the
effect of negative votes.

    Approval of Ernst & Young LLP as Sync's independent auditors requires the
affirmative vote of at least a majority of the shares present in person or by
proxy at the meeting and entitled to vote. Uninstructed shares are entitled to
vote on this matter. Therefore, abstentions and broker non-votes have the effect
of negative votes.

VOTING BY SYNC DIRECTORS AND EXECUTIVE OFFICERS

    At the close of business on the record date, directors and executive
officers of Sync and their affiliates owned and were entitled to vote
            shares of Sync common stock, which represented approximately   % of
the shares of Sync common stock outstanding on that date. Each Sync director and
executive officer has indicated his or her present intention to vote, or cause
to be voted, the Sync common stock owned by him or her "for" adoption of the
merger agreement.

VOTING OF PROXIES

    All shares represented by properly executed proxies received in time for the
annual meeting will be voted at the annual meeting in the manner specified by
the holders. Properly executed proxies that do not contain voting instructions
will be voted "for" adoption of the merger agreement.

    The persons named as proxies by a stockholder may propose and vote for one
or more adjournments of the annual meeting, including adjournments to permit
further solicitations of proxies. No proxy voted against the proposal to adopt
the merger agreement will be voted in favor of any such adjournment or
postponement.

    Other than the matter described under the heading "Possible Stockholder
Proposal," Sync is not aware of, and does not expect that, any matters other
than the proposals described in this proxy statement/prospectus will be brought
before the annual meeting. If, however, the Sync board of directors properly
presents other matters, the persons named as proxies will vote in accordance
with their judgment.

REVOCABILITY OF PROXIES

    The grant of a proxy on the enclosed form of proxy does not preclude a
stockholder from voting in person at the annual meeting. A stockholder may
revoke a proxy at any time prior to its exercise by filing with the Secretary of
Sync a duly executed revocation of proxy, by submitting a duly executed

                                       27
<PAGE>
proxy to the Secretary of Sync bearing a later date or by appearing at the
annual meeting and voting in person. Attendance at the annual meeting will not
itself constitute revocation of a proxy.

SOLICITATION OF PROXIES

    Sync will bear the cost of the solicitation of proxies from its
stockholders. In addition to solicitation by mail, the directors, officers and
employees of Sync and its subsidiaries may solicit proxies from stockholders by
telephone or other electronic means or in person. Sync will cause brokerage
houses and other custodians, nominees and fiduciaries to forward solicitation
materials to the beneficial owners of stock held of record by such persons. Sync
will reimburse such custodians, nominees and fiduciaries for their reasonable
out-of-pocket expenses in doing so.

    MacKenzie Partners will assist in the solicitation of proxies by Sync. Sync
will pay MacKenzie Partners an estimated fee of $25,000, plus reimbursement of
certain out-of-pocket expenses, and will indemnify MacKenzie Partners against
any losses arising out of MacKenzie Partners' proxy soliciting services on
behalf of Sync.

    THE MATTERS TO BE CONSIDERED AT THE SYNC ANNUAL MEETING ARE OF GREAT
IMPORTANCE TO THE STOCKHOLDERS OF SYNC. ACCORDINGLY, STOCKHOLDERS ARE URGED TO
READ AND CAREFULLY CONSIDER THE INFORMATION PRESENTED IN THIS PROXY
STATEMENT/PROSPECTUS, AND TO COMPLETE, DATE, SIGN AND PROMPTLY RETURN THE
ENCLOSED PROXY IN THE ENCLOSED POSTAGE-PAID ENVELOPE.

                                   THE MERGER

    The following discussion summarizes the material terms of the merger and the
merger agreement. Stockholders should read carefully the merger agreement, which
is attached as Annex A to this proxy statement/prospectus.

OWNERSHIP OF SYNC AND ENTRADA FOLLOWING THE MERGER; STOCK OPTIONS

    Immediately following the merger, (i) Sync will own 100% of the issued and
outstanding shares of Entrada common stock, and (ii) Parent will own 50% of the
issued and outstanding shares of Sync common stock. In addition, certain
employees of Entrada will be granted options to purchase shares of Sync common
stock which, in the aggregate, shall equal the number of shares of Sync common
stock issuable upon the exercise of all of the outstanding Sync options at the
time of the merger.

BACKGROUND TO THE MERGER

    Business combinations have been a significant part of the networking
industry. From time to time, Sync has developed various corporate development
programs to review and evaluate potential business combinations, corporate
acquisition opportunities, strategic alliances, joint development programs and
other strategic transactions involving other participants in the networking,
communications and computer industries and related industries, with the aim of
obtaining and developing access to complementary technologies, products and
distribution channels. Over the past two years, Sync has actively searched for a
desirable business combination in an effort to maximize value to it
stockholders.

    On May 27, 1999, as part of Sync's corporate development efforts, Sync's
president and chief executive officer, Dick Martin, and chairman of the board,
Gregorio Reyes, met with a representative of Alliant Partners and discussed
various strategic alternatives for Sync. On June 7, 1999, Sync engaged Alliant
Partners to search for strategic alternatives for Sync.

    Upon commencing the assignment, Alliant prepared a package of information
regarding Sync, as well as a prospect list of thirty-one potential merger
partners. Contacts were made with each of these thirty-one companies over the
subsequent thirty day period. Of the thirty-one companies contacted, eleven
requested that Alliant provide additional information regarding Sync. Meetings
were subsequently held with five of the target companies during the months of
July and August.

    During the month of July 1999, Sync senior management met with Par Chadha,
chairman, president and chief executive officer of Parent, and Leonard Hecht, a
director of Parent, to discuss the possibility of a business combination between
the two companies. In connection with such meeting, Sync and Parent signed a
non-disclosure agreement.

    On July 27, 1999, the Sync board of directors held a regular meeting. During
that meeting, the Sync board and management discussed various strategic issues
and the status of Sync's operations. In addition, the Sync board received a
status report from Alliant Partners on its progress to find a suitable strategic
alternative for Sync.

    During the months of July and August, 1999, no further meetings with
additional prospects were scheduled, and all of the prospects except Entrada
indicated that they did not have any interest in proceeding with a transaction.
While Entrada did indicate some interest in a transaction with Sync,
representatives of Entrada indicated that they were not open to the idea of an
outright acquisition.

    On August 28, 1999, Alliant reported to senior management of Sync that it
appeared unlikely that a transaction could be consummated with a larger company
that would provide liquidity to Sync's stockholders, or other usual and
customary benefits such as a premium to market. Based on market conditions,
Alliant recommended that discussions be held with Entrada, while an additional
thirteen

                                       29
<PAGE>
prospects, consisting of large networking companies, were contacted regarding a
potential business combination with Sync.

    On October 20, 1999, members of Sync's senior management and board of
directors met with members of Parent's senior management and board to discuss
whether a strategic combination of Sync and Entrada or other alternative would
be feasible and the possible framework for such a transaction.

    On November 1, 1999, Mr. Reyes and Mr. Guerry met with Mr. Par Chadha and
other representatives of Entrada to conduct further discussions regarding the
framework and structure for such a strategic combination of the two companies.
It was mutually agreed that Sync's board would formally consider a merger of
Sync and Entrada at its next board meeting.

    On November 15-16, 1999, members of Sync's executive management met with
Mr. Par Chadha and representatives of Entrada and Entrada's parent to review all
significant aspects of Entrada's operations including, but not limited to,
research and development projects, sales channels and customer relationships,
financial statements, product offerings and personnel.

    During the months of September, October and November 1999, Alliant made
contact with the other thirteen prospects previously identified and was unable
to generate any interest in a transaction for Sync that would provide either
cash or a highly liquid security for Sync's stockholders.

    On December 16, 1999, the Sync board of directors held a regular meeting.
During that meeting, the Sync board, its management and representatives of
Alliant Partners discussed the general terms of the proposed merger and the
assessment of Sync's management of Entrada's network access business. At that
meeting, it was determined that the terms of the proposed merger were not
acceptable and Alliant, accordingly, informed Parent that Sync was not
interested in completing the merger as proposed. The board, however, indicated
its agreement that a merger with an acceptable valuation should be considered.

    On January 14, 2000, the president and chief executive officer of Parent
called Alliant Partners to reengage in further discussions with revised terms
and an acceptable valuation. Based on a series of discussions between
representatives of Alliant Partners and Parent, an agreement in principal was
reached to pursue a transaction between Sync and Entrada on a basis under which
the current Sync stockholders would own 50% of Sync following the proposed
merger.

    Even after the agreement in principal was reached, Alliant continued to
explore alternative transactions, but was unable to identify any prospective
merger partner other than Entrada.

    Between February 1, 2000 and April 9, 2000, the parties and their respective
financial and legal advisors conducted intensive on- and off-site due diligence
reviews and held numerous meetings and discussions regarding possible terms and
structures for the proposed combination. As part of their due diligence, each
party reviewed public and non-public documents and information of the other
party and heard presentations by representatives of the other party.

    On February 11, 2000, a draft of the merger agreement was provided by
Greenbaum, Rowe, Smith, Ravin, Davis & Himmel, LLP legal counsel for Parent, to
Sync. From February 11 through April 10, 2000 representatives of Sync and Parent
and their respective legal advisors held numerous meetings and discussions
regarding the terms of the proposed combination.

    On March 22, 2000, senior management of Sync met with personnel of Parent to
discuss the sales outlook for Sync and Entrada, respectively.

    On April 7, 2000 and April 10, 2000 the Sync board of directors met to
review the proposed transaction and alternative business strategies. At the
meeting, Sync management, Alliant Partners and Orrick, Herrington, & Sutcliffe,
LLP each made presentations to the Sync board, and copies of the draft merger
agreement and other pertinent information were distributed to the Sync board.
After

                                       30
<PAGE>
discussing the terms of the proposed transaction, the Sync board voted at the
April 10 meeting to give approval to the combination of Sync and Entrada on the
terms set forth in the then current draft of the merger agreement.

    On April 11, 2000, following the execution and delivery of the merger
agreement, Sync and Parent issued a joint press release announcing the merger.

REASONS FOR THE MERGER AND BOARD OF DIRECTORS RECOMMENDATION

    REASONS FOR THE MERGER.  In reaching its decision to approve the merger
agreement and the merger and to recommend that Sync stockholders approve the
issuance of shares of Sync common stock in connection with the merger, the Sync
board of directors consulted with its management team and advisors and
independently considered the proposed merger agreement and the transactions
contemplated by the merger agreement. The following discussion of the factors
considered by the Sync board of directors in making its decision is not intended
to be exhaustive but includes all material factors considered by the Sync board
of directors.

    The Sync board of directors considered the following factors as reasons that
the merger will be beneficial to Sync and its stockholders:

    - the opportunity to enter into the emerging and rapidly growing market for
      storage area networking for which Entrada has already begun development of
      product offerings

    - the anticipated contributions of Parent, which has past experience in
      working with developing high technology companies

    - the complementary nature of Sync's and Entrada's technologies and product
      offerings across a range of products and possible synergies from combining
      Sync and Entrada

    - the opportunity for Sync to distribute its products through Entrada's more
      established reseller and distribution channels and through its stronger
      presence in the OEM market

    - the potential of the combined companies to deliver more complete network
      access solutions to customers across the local and wide area networks, and
      to develop products in new high growth technologies and markets, including
      storage networking, with enhanced network manageability and reduced costs

    - the potential of the combined companies to achieve operational
      efficiencies and other synergies including improved manufacturing capacity
      utilization, procurement savings, corporate overhead reductions and other
      cost savings

    - the terms and conditions of the merger agreement, including the ability of
      the Sync board of directors to consider other nonsolicited strategic
      transaction proposals prior to the closing of the merger

    - detailed financial analysis and pro forma and other information with
      respect to the companies presented by Alliant Partners to the Sync board
      of directors, including Alliant Partner's opinion that the consideration
      to be received by Sync stockholders pursuant to the exchange ratio in the
      merger is fair to the Sync stockholders from a financial point of view.

    In the course of deliberations, the Sync board of directors also considered
a number of additional factors relevant to the merger, including:

    - information relating to the business, assets, management, competitive
      position, financial performance and condition, technology, trading
      performance and prospects of each of Sync and Entrada before and after
      giving effect to the merger

    - current industry, market and economic conditions

                                       31
<PAGE>
    - the belief that the terms of the merger agreement, including the parties'
      representations, warranties and covenants, and the conditions to their
      respective obligations, are reasonable

    - the prospects of Sync if it were to continue as an independent company

    - the potential for other third parties to enter into strategic
      relationships with or to acquire Sync

    - the impact of the merger on Sync's and Entrada's customers, suppliers and
      employees

    - reports from Sync management and from legal and financial advisors as to
      the results of their due diligence investigations of Entrada

    - the likelihood that the merger would be completed.

    The Sync board of directors also identified and considered a number of
potentially negative factors in its deliberations concerning the merger,
including but not limited to:

    - the risk that the potential benefits sought in the merger might not be
      fully realized

    - the possibility that the merger might not be consummated

    - the risk that the issuance of Sync common stock in the merger could be
      dilutive to current Sync stockholders

    - the effect of the public announcement of the merger on (a) demand for the
      products and services of Sync, its customer relations, its operating
      results and its stock price, and (b) the ability of Sync to attract and
      retain key management, account managers, network engineers and other
      personnel

    - the substantial charges to be incurred in connection with the merger,
      including costs of integrating the businesses and transaction expenses
      from the merger

    - the risk that despite the efforts of the combined companies, key
      management and other personnel might not remain employed by the combined
      companies

    - risks associated with fluctuations in Sync's stock price prior to the
      closing of the merger

    - various other risks.

    The foregoing discussion is not exhaustive of all factors considered by
Sync's board of directors. The Sync board of directors believed that certain
risks were unlikely to occur, that Sync could avoid or mitigate others, and
that, overall, these risks were outweighed by the potential benefits of the
merger.

    In view of the variety of factors considered in connection with its
evaluation of the merger agreement and the merger, the Sync board of directors
did not find it practicable to and did not quantify or otherwise assign relative
weight to the specific factors considered in reaching its determination. In
addition, individual members of the Sync board of directors may have given
different weight to different factors.

    RECOMMENDATION OF THE SYNC BOARD OF DIRECTORS.  After careful consideration,
the Sync board of directors has unanimously determined that the terms of the
merger agreement and the merger are fair to, and in the best interests of, the
stockholders of Sync and has approved the merger agreement and the merger. The
Sync board of directors recommends that the stockholders of Sync vote "for" the
proposal to authorize the issuance of Sync common stock under the merger
agreement for completion of the merger.

FAIRNESS OPINION OF FINANCIAL ADVISOR

    Pursuant to an engagement letter dated June 7, 1999, Sync retained Alliant
Partners to render an opinion regarding the fairness, from a financial point of
view, of the merger to the Sync stockholders.

                                       32

    On April 10, 2000, in a 5:00 a.m. PST conference call, the Sync board of
directors met and approved the merger. At this meeting and during the previous
board meeting on Friday, April 7, 2000, Alliant Partners delivered to the Sync
Research board of directors its opinion by teleconference (the "Alliant
Opinion") that as of April 10, 2000, and based on the matters described therein,
the transaction was fair, from a financial point of view, to the Sync
stockholders. Alliant Partners noted that its presentation on the financial
terms of the merger was based on the closing stock prices and general market
conditions as of April 7, 2000. No limitations were imposed by Sync on the scope
of Alliant Partners' investigations or the procedures to be followed by Alliant
Partners in rendering the Alliant Opinion. The exchange ratio was determined
through negotiations between the management of Sync and Parent. In furnishing
the Alliant Opinion, Alliant Partners was not engaged as an agent or fiduciary
of Sync's stockholders or any other third party.

    The full text of the Alliant Opinion, which sets forth, among other things,
assumptions made, matters considered and limitations on the review undertaken,
is attached hereto as Annex B and is incorporated herein by reference.
STOCKHOLDERS OF SYNC ARE URGED TO READ THE ALLIANT OPINION IN ITS ENTIRETY. THE
ALLIANT OPINION WAS PREPARED FOR THE BENEFIT AND USE OF THE SYNC BOARD OF
DIRECTORS IN ITS CONSIDERATION OF THE MERGER AND DOES NOT CONSTITUTE A
RECOMMENDATION TO STOCKHOLDERS OF SYNC AS TO HOW THEY SHOULD VOTE AT THE ANNUAL
MEETING IN CONNECTION WITH THE MERGER. The Alliant Opinion does not address the
relative merits of the merger and any other transactions or business strategies
discussed by the Sync board of directors as alternatives to the merger agreement
or, except with respect to the fairness of the exchange ratio, from a financial
point of view, to the holders of Sync common stock, the underlying business
decision of the Sync board to proceed with or effect the merger. The summary of
the Alliant Opinion set forth in this proxy statement/prospectus is qualified in
its entirety by reference to the full text of the Alliant Opinion.

    In connection with the preparation of the Alliant Opinion, Alliant Partners,
among other things, engaged in the following activities: reviewed the terms of
the Agreement and Plan of Merger dated April 10, 2000 and the associated
exhibits thereto; reviewed the Sync Form 10-K for the fiscal years ended
December 1998 and 1999, including the audited financial statements included
therein; reviewed certain internal financial and operating information relating
to Sync prepared by Sync management; participated in discussions with Sync
management concerning the operations, business strategy, financial performance
and prospects for Sync; reviewed the recent reported closing prices and trading
activity for Sync common stock; compared certain aspects of the financial
performance and business strategy of Sync and Entrada with comparable public
companies; analyzed available information, both public and private, concerning
other mergers and acquisitions comparable in whole or in part to the merger;
reviewed Form 10-Q for the period ending October 31, 1999, Forms 10-K for 1998,
1997 and 1996, and several Forms 8-K of Parent; participated in discussions with
management of Parent concerning the operations, business strategy, financial
performance and prospects for Entrada and its strategic rationale for the
merger; reviewed the recent reported closing prices and trading activity for the
common stock of Parent; reviewed recent equity analyst reports covering
Entrada's business sector and Parent; considered the effect of the merger on the
future financial performance of the consolidated entity; participated in
discussions related to the merger among Parent, Sync, and their respective
financial and legal advisors; and conducted other financial studies, analyses
and investigations as Alliant Partners deemed appropriate for purposes of
rendering the Alliant Opinion.

    In conducting its review and rendering the Alliant Opinion, Alliant Partners
relied upon and assumed the accuracy and completeness of the financial
statements and other information provided by Sync and Parent or otherwise made
available to Alliant Partners and did not assume responsibility independently to
verify such information. Alliant Partners further relied upon the assurances of
Parent's and Sync's management that the information provided was prepared on a
reasonable basis in accordance with industry practice, that with respect to
financial planning data, the information provided reflected the best currently
available estimates and good faith judgments of Parent's and Sync's

                                       33
<PAGE>
management as to the expected future financial performance of Sync and Entrada,
and that such parties were not aware of any information or facts that would make
the information provided to Alliant Partners incomplete or misleading. Without
limiting the generality of the foregoing, for the purpose of the Alliant
Opinion, Alliant Partners assumed that neither Sync nor Entrada was a party to
any pending transaction, including external financing, recapitalizations,
acquisitions or merger discussions, other than the merger or in the ordinary
course of business. Alliant Partners also assumed that the merger would be free
of Federal tax to the Sync stockholders.

    In arriving at the Alliant Opinion, Alliant Partners did not perform any
appraisals or valuations of specific assets or liabilities of Sync or Entrada
and was not furnished with any such appraisals or valuations.

    Without limiting the generality of the foregoing, Alliant Partners did not
undertake any independent analysis of any pending or threatened litigation,
possible unasserted claims or other contingent liabilities, to which Sync,
Entrada, Parent or any of their respective affiliates was a party or may be
subject and, at Sync's direction and with its consent, the Alliant Opinion made
no assumption concerning, and therefore did not consider, the possible assertion
of claims, outcomes or damages arising out of any such matters. Although
developments following the date of the Alliant Opinion may affect the Alliant
Opinion, Alliant Partners assumed no obligation to update, revise or reaffirm
the Alliant Opinion.

    Following is a summary explanation of the various sources of information and
valuation methodologies employed by Alliant Partners in conjunction with
rendering its opinion to the Sync board of directors.

    COMPARABLE COMPANY ANALYSIS

    Alliant Partners compared certain financial information and valuation ratios
relating to Entrada to corresponding publicly available data and ratios from a
group of selected publicly traded companies deemed comparable to Entrada. The
comparable companies selected included twenty-two publicly traded companies in
the business of telecommunications and networking. The following financial
information was reviewed by Alliant Partners for each selected company:
Enterprise Value, calculated as the market capitalization of the selected
company, plus such company's debt, less such company's cash; Trailing Twelve
Months revenue, calculated as the most recent four quarters revenue as filed
with the Securities and Exchange Commission; Calendar Year 1999 Revenue; Prior
Year Revenue Growth Rate; and Current Year Revenue Growth Rate. The companies
assessed by Alliant Partners included: 3Com Corporation, ACT Networks Inc., ADC
Telecommunications, ADTRAN Inc., Asante Technologies Inc., Cabletron
Systems Inc., Cisco Systems Inc., Digi International, General DataComm
Industries, Harris Corporation, Hypercom Corporation, Interphase Corporation,
Larscom Incorporated, Lucent Technologies Inc., Motorola Inc., Newbridge
Networks Corp., Nortel Networks Corp., Paradyne Networks Inc., Verilink
Corporation, Visual Networks Inc., Westell Technologies Inc. and Xircom Inc.

    The comparable companies had an Enterprise Value/TTM Revenue ratio range of
 .5x to 35x with a weighted narrow average (narrow average excludes the highest
and lowest estimates) of 4.3x; Enterprise Value/TTM Earnings (where positive)
ratio range of 10.8x to 206x with a weighted narrow average of 79x; (Enterprise
Value/1 million)/Headcount ratio range of .2x to 20x with a weighted narrow
average of 1.2x. After making certain adjustments for differences in liquidity,
performance and size, this analysis yielded an implied Entrada equity value of
$32.1 million.

    No company utilized as a comparison in the Comparable Company Analysis is
identical to Entrada or Sync. In evaluating the comparable companies, Alliant
Partners made judgments and assumptions with regard to industry performance,
general business, economic, market and financial conditions and other matters,
many of which are beyond the control of Entrada or Sync.

                                       34

    COMPARABLE TRANSACTION ANALYSIS

    Alliant Partners reviewed twenty-three comparable merger and acquisition
transactions from November 1998 through April 2000, which involve sellers
sharing many characteristics with Entrada including revenue size, products
offered and business model. These comparable transactions of companies in the
telecommunications and networking sectors are: ADC Telecommunications, Inc.'s
acquisition of PairGain Technologies, Inc.; Lucent Technologies Inc.'s
acquisition of Ortel Corp.; Cisco Systems Inc.'s acquisition of Pirelli Optical
Systems; Westell Technologies Inc.'s acquisition of Teltrend, Inc.; Cisco
Systems Inc.'s acquisition of Aironet Wireless Communications Inc.; Zhone
Technologies Inc.'s acquisition of Premisys Communications, Inc.; Alcatel SA's
acquisition of Genesys Telecommunications Laboratories Inc.; Motorola Inc.'s
acquisition of General Instrument Corp.; DLZ Corp.'s acquisition of Digital Link
Corp. (Quick Eagle Networks); Cisco Systems Inc.'s acquisition of Monterey
Networks; Nortel Networks Corp.'s acquisition of Periphonics Corp.; Lucent
Technologies Inc.'s acquisition of Excel Switching Corp.; Lucent
Technologies Inc.'s acquisition of Nexabit Networks Inc.; Newbridge Networks
Corp.'s acquisition of Stanford Telecommunications Inc.; ADC
Telecommunications Inc.'s acquisition of Saville Systems; Alcatel SA's
acquisition of XYLAN Corp.; 3COM Corp.'s acquisition of NBX Corp.; Verilink
Corp.'s acquisition of TXPORT, Inc.; Lucent Technologies Inc.'s acquisition of
Agere, Inc.; Cisco Systems Inc.'s acquisition of Altiga Networks; Cisco
Systems Inc.'s acquisition of Compatible Systems Corp.; Efficient Networks'
acquisition of FlowPoint Corporation; and Cisco Systems Inc.'s acquisition of
Tasmania Network Systems Inc.

    The Price/Revenue multiples of the twenty-three transactions range from .27x
to 55x with a weighted average of 12x. The Price/Earnings ratio ranged
from--506x to 339x, with a narrow average of 13x. This was not a meaningful
multiple as Entrada had negative earnings. The Price/Headcount multiple ranged
from .05x to 19x, with the narrow average of 3x. The Comparable Transaction
Analysis yielded an implied Entrada equity value of $87.2 million.

    Estimated multiples paid in the comparable transactions were based on
information obtained from public filings, public company disclosures, press
releases, industry and popular press reports, research reports, databases and
other sources. No company, transaction or business used in the Comparable
Company Analysis or Comparable Transaction Analysis as a comparison is identical
to Entrada or the merger. Accordingly, an analysis of the results of the
foregoing is not entirely mathematical; rather it involves complex
considerations and judgments concerning differences in financial and operating
characteristics and other factors that could affect the acquisition, public
trading and other values of the comparable companies, comparable transactions or
the business segment, company or transactions to which they are being compared.

    COMPARISON OF ENTRADA WITH SYNC RESEARCH

    Alliant Partners evaluated Sync and Entrada in terms of business strategy,
business performance and various financial metrics to determine the relative
value of each if the two companies were combined as one entity. Financial
metrics included a comparison of revenues, EBIT, earnings, various margins,
assets, fixed assets, investment, employees, and growth rates. Based on this
analysis, Alliant Partners concluded that Entrada would represent on average a
49% share of the combined companies.

    ENTRADA AS A PERCENTAGE OF FIBR MARKET VALUATION

    In this analysis, Alliant Partners evaluated Entrada to determine its
percentage of the market valuation of Parent (NASDAQ: FIBR). In the months
preceding the transaction, Parent had seen its share price rise at an
exceptional rate, mainly due to the market appetite for Optical Networking
companies. To determine Entrada's share of the valuation of Parent, Alliant
Partners used a 20 day average share price of $105.51, (dates from March 13
through April 7, 2000) which translated to a market capitalization of
$1,052.59 million.

                                       35
<PAGE>
    In determining the value of Entrada, Alliant Partners used three methods:
estimates from public investment research; percentage of revenues, based on the
Parent's management revenue estimates and industry growth rates; and a
conservative estimate of 1 X estimated fiscal year 2000 revenues. This analysis
produced an average value for Entrada of $37.1 million.

    CONCLUSION

    While the foregoing summary describes certain analyses and factors that
Alliant Partners deemed material in its presentation to the Sync board of
directors, it is not a comprehensive description of all analyses and factors
considered by Alliant Partners. The preparation of a fairness opinion is a
complex process that involves various determinations as to the most appropriate
and relevant methods of financial analysis and the application of these methods
to the particular circumstances and, therefore, such an opinion is not readily
susceptible to summary description. Alliant Partners believes that its analyses
must be considered as a whole and that selecting portions of its analyses and of
the factors considered by it, without considering all analyses and factors,
would create an incomplete view of the evaluation process underlying the Alliant
Opinion. Several analytical methodologies were employed and no one method of
analysis should be regarded as critical to the overall conclusion reached by
Alliant Partners. Each analytical technique has inherent strengths and
weaknesses, and the nature of the available information may further affect the
value of particular techniques. The conclusions reached by Alliant Partners are
based on all analyses and factors taken as a whole and also on application of
Alliant Partners' own experience and judgment. Such conclusions may involve
significant elements of subjective judgment and qualitative analysis. Alliant
Partners therefore gives no opinion as to the value or merit standing alone of
any one or more parts of the analysis it performed. In performing its analyses,
Alliant Partners considered general economic, market and financial conditions
and other matters, many of which are beyond the control of Sync and Entrada. The
analyses performed by Alliant Partners are not necessarily indicative of actual
values or future results, which may be significantly more or less favorable than
those suggested by such analyses. Accordingly, analyses relating to the value of
a business do not purport to be appraisals or to reflect the prices at which the
business actually may be purchased. Furthermore, no opinion is being expressed
as to the prices at which shares of Sync common stock may trade at any future
time.

    Pursuant to an engagement letter dated June 7, 1999, Alliant Partners
received a fee of $100,000 for the fairness opinion rendered to the Sync board
or directors. Sync has also agreed to reimburse Alliant Partners for its out of
pocket expenses and to indemnify and hold harmless Alliant Partners and its
affiliates and any person, director, employee or agent acting on behalf of
Alliant Partners or any of its affiliates, or any person controlling Alliant
Partners or its affiliates, for certain losses, claims, damages, expenses and
liabilities relating to or arising out of services provided by Alliant Partners
as financial advisor to Sync. The terms of the fee arrangement with Alliant
Partners, which Sync and Alliant partners believe are customary in transactions
of this nature, were negotiated at arm's length between Sync and Alliant
Partners, and the Sync board was aware of such fee arrangements.

    Alliant Partners was retained based on Alliant Partners' experience as a
financial advisor in connection with mergers and acquisitions and in securities
valuations generally, as well as Alliant Partners' investment banking
relationship and familiarity with Sync. Alliant Partners has provided financial
advisory and investment banking services to Sync in the past.

    As part of its investment banking business, Alliant Partners is frequently
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, sales and divestitures, joint ventures and strategic
partnerships, private financings and other specialized studies.

    PRIVATE PLACEMENT FINANCING; BRING-DOWN OF ALLIANT OPINION

    Subsequent to the issuance of the initial fairness opinion by Alliant
Partners, Sync closed a private placement financing on May 12, 2000, in which
Entrada Holdings LLC ("Entrada Holdings"), purchased 700,000 shares of Series A
Preferred Stock from Sync for approximately $3.19 per share, which was the
average closing sale price of Sync stock for the ten days ended April 28, 2000.
An affiliate of Entrada Holdings is a shareholder of Parent. Sync raised a total
of $2,235,625 in cash in the private placement. The shares of Series A Preferred
Stock are convertible into shares of Sync common stock on a one-for-one basis,
and will be automatically converted into shares of Sync common stock on the
closing of the merger. Entrada Holdings may request that Sync register the
shares of Sync common stock issuable on the conversion of the Series A Preferred
Stock on a Form S-3 registration statement for resale in the public market at
any time after the earlier of: (i) ninety (90) days after the closing of the
merger, or (ii) May 12, 2001. If the merger has not closed by a specified date,
Entrada Holdings will receive certain protective provisions, including the right
to designate one member to Sync's board of directors for so long as a specified
percentage of the shares of Series A Preferred Stock are outstanding. In
connection with the private placement, Sync paid a fee equal to five percent
(5%) of the aggregate purchase price to Andersen Weinroth Capital Corp., an
investment firm affiliated with Entrada Holdings.

    After careful consideration, the management of Sync has determined that,
notwithstanding the fact that the merger consideration payable by Sync to Parent
will increase by an additional 700,000 shares of Sync common stock as a result
of the private placement, the terms of the merger agreement and the merger
remain fair to, and in the best interests of, the stockholders of Sync. Alliant
Partners has provided Sync with an updated opinion, subsequent to the closing of
the private placement financing, to supplement its initial opinion regarding the
fairness, from a financial point of view, of the merger to the Sync
stockholders. Alliant Partners delivered to the Sync board of directors its
opinion dated          , 2000 (the "Bring-Down Alliant Opinion"), confirming
that the private placement financing described above does not impact the
conclusion that the merger transaction is fair, from a financial point of view,
to the Sync stockholders. The full text of the Bring-Down Alliant Opinion is
attached hereto as Annex C and is incorporated herein by reference. STOCKHOLDERS
OF SYNC ARE URGED TO READ THE BRING-DOWN ALLIANT OPINION IN ITS ENTIRETY. THE
BRING-DOWN ALLIANT OPINION WAS PREPARED FOR THE BENEFIT AND USE OF THE SYNC
BOARD OF DIRECTORS AND DOES NOT CONSTITUTE A RECOMMENDATION TO STOCKHOLDERS OF
SYNC AS TO HOW THEY SHOULD VOTE AT THE ANNUAL MEETING IN CONNECTION WITH THE
MERGER. The summary of the Bring-Down Alliant Opinion set forth in this proxy
statement/prospectus is qualified in its entirety by reference to the full text
of the Bring-Down Alliant Opinion.

INTERESTS OF SYNC DIRECTORS AND MANAGEMENT IN THE MERGER

    In considering the recommendation of the Sync board of directors in favor of
the merger, stockholders of Sync should be aware that members of the Sync board
of directors and executive officers of Sync have interests in the merger that
are different from, or in addition to, the interests of stockholders of Sync.
Such interests relate to or arise from, among other things:

    - all executive officers of Sync are parties to agreements that provide for
      the partial vesting of any unvested options upon a change in control and
      certain severance benefits if such executive officer is terminated
      following a corporate transaction such as the merger

    - Mr. Gregorio Reyes, the current Chairman of the Sync board of directors,
      will remain as a director of Sync following the merger, and certain
      current executive officers of Sync will remain as executives of Sync
      following the merger

    - Mr. Reyes is party to an agreement that provides for the full vesting of
      any unvested options upon a change in control and certain severance
      benefits if he is terminated following a corporate transaction such as the
      merger.

                                       37
<PAGE>
    Each of these additional interests are described below, to the extent
material, and except as described below these individuals have, to the knowledge
of Sync and Entrada, no material interest in the merger apart from those of
stockholders generally. The Sync board of directors was aware of, and considered
the interests of, their directors and executive officers in approving the merger
agreement and the merger.

    BOARD OF DIRECTORS.  Upon consummation of the merger, the board of directors
of Sync intends to increase the number of directors who sit on the board from
four to five, and to appoint Dr. Kanwar J.S. Chadha, currently the President of
Entrada and the intended Chief Executive Officer of Sync following the merger,
to fill such created vacancy. Further, it is the present intention of Sync and
Entrada to have Messrs. Guerry and Schroeder step down from the board upon
consummation of the merger, and be replaced by Leonard N. Hecht, currently a
director of Parent, and Rohit Phansalkar, currently a director of Parent and a
partner of Andersen Weinroth & Co. LP, affiliates of which own all of the
outstanding Series A Preferred Stock of Sync and are stockholders of Parent.
Therefore, assuming that the Sync stockholders authorize the issuance of Sync
common stock under the merger agreement for completion of the merger and elect
the slate of directors that the Sync board of directors has nominated, the board
of directors of Sync following the merger will consist of Gregorio Reyes,
currently the Chairman of Sync's board of directors, Dr. Chadha, Charles A.
Haggerty, currently a director of Sync, Mr. Hecht and Mr. Phansalkar.

    EXECUTIVE OFFICERS.  The Chief Executive Officer of Sync following the
merger will be Dr. Kanwar J.S. Chadha, who is currently the President of
Entrada. William K. Guerry, currently the Chief Executive Officer, President and
Chief Financial Officer of Sync, will be the Chief Operating Officer, Chief
Financial Officer and Vice President-Finance and Administration of Sync
following the merger. Anand Mehta, currently the Chief Technology Officer and
Vice President-Engineering of Entrada, will be the Chief Technology Officer and
Vice President-Engineering of Sync following the merger. Arthur Trakas,
currently the Executive Vice President-Sales and Marketing of Parent and
Entrada, will be the Vice President-Sales and Marketing of Sync following the
merger.

    CHANGE IN CONTROL AGREEMENTS.  Sync has entered into change in control
agreements with all of the executive officers and the Chairman of the board of
Sync. Pursuant to these agreements, 50% (100% in the case of Mr. Reyes) of each
officer's unvested options will become fully vested as a result of the merger.
In addition, if the employment of any officer is terminated within one year of
the merger other than for cause, the officer will become entitled to

    - an amount equal to 100% of his annual salary, payable monthly for twelve
      months (twenty-four months in the case of the Chief Executive Officer)
      following the date of termination

    - continued health, dental and life insurance coverage for twelve months

    - have all remaining unvested Sync stock options vest at the same monthly
      rate as prior to the merger and in accordance with the applicable stock
      option plan.

ACCOUNTING TREATMENT

    The merger will be accounted for as an acquisition of Sync by Entrada under
the "purchase" method of accounting in accordance with generally accepted
accounting principles.

APPRAISAL RIGHTS

    Holders of Sync common stock are not entitled to dissenters' appraisal
rights under Section 262 of the Delaware General Corporation Law with respect to
the merger or the proposals to be considered at the Sync annual meeting.

                                       38
<PAGE>
FORM OF THE MERGER; NAME CHANGE

    Subject to the terms and conditions of the merger agreement and in
accordance with Delaware law, at the effective time of the merger, Sync Research
Acquisition Corp., a wholly-owned subsidiary of Sync formed for the purpose of
the merger which is a party to the merger agreement, will merge with and into
Entrada. Entrada will survive the merger as a wholly owned Delaware subsidiary
of Sync, and Sync will continue under the name "Entrada Networks, Inc."

MERGER CONSIDERATION

    At the effective time of the merger, each outstanding share of Entrada
common stock will be converted into the right to receive shares of Sync common
stock, except that treasury stock and stock held by Entrada or any subsidiary of
Entrada will be canceled. As of the effective time of the merger, all shares of
Entrada common stock will no longer be outstanding and will automatically be
canceled and will cease to exist and each holder of a certificate representing
any shares of Entrada common stock will cease to have any rights as a
stockholder except the right to receive Sync common stock in the merger. The
exchange ratio was determined through arm's-length negotiations between Sync and
Entrada.

CONVERSION OF SHARES

    The conversion of Entrada common stock into the right to receive Sync common
stock will occur automatically at the effective time of the merger. After the
effective time of the merger, each certificate that previously represented
shares of Entrada common stock will represent only the right to receive the Sync
common stock into which such shares were converted in the merger. All shares of
Sync common stock issued upon conversion of shares of Entrada common stock will
be issued in full satisfaction of all rights relating to such shares of Entrada
common stock.

EFFECTIVE TIME OF THE MERGER

    The merger will become effective upon the filing of the certificate of
merger with the Delaware Secretary of State or such later time as is agreed upon
by Sync and Entrada and specified in the certificate of merger. The filing of
the certificate of merger will occur as soon as practicable, but no later than
the second business day, after satisfaction or waiver of the conditions to the
completion of the merger described in the merger agreement unless another date
is agreed to in writing by Sync and Entrada.

STOCK EXCHANGE LISTING OF SYNC COMMON STOCK

    It is a condition to the completion of the merger that Sync common stock
issuable to Parent in the merger be approved for listing on the Nasdaq National
Market, subject to official notice of issuance.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

    The following are the material United States federal income tax consequences
of the merger to Sync and the Sync stockholders. The following discussion is
based on and subject to the Internal Revenue Code of 1986, its legislative
history, applicable Treasury regulations, administrative rulings and court
decisions currently in effect, all of which are subject to change at any time,
possibly with retroactive effect. For United States federal income tax purposes,
regardless of whether the merger will be treated as a reorganization within the
meaning of Section 368(a) of the Internal Revenue Code, no gain or loss will be
recognized by Sync or the Sync stockholders as a result of the merger.

                                       39
<PAGE>
REGULATORY MATTERS

    UNITED STATES ANTITRUST.  Under the Hart-Scott-Rodino Act and related rules,
certain transactions, including the merger, may not be completed unless certain
waiting period requirements have been satisfied. Sync and Entrada each intend to
file soon a Notification and Report Form with the Antitrust Division of the
Department of Justice and the Federal Trade Commission, and expect the waiting
period to expire approximately thirty (30) days after such date of filing,
unless earlier terminated, or extended by a "second request" for additional
information and materials by the Antitrust Division or the Federal Trade
Commission. At any time before or after the effective time of the merger, the
Antitrust Division, the Federal Trade Commission or others could take action
under the antitrust laws, including seeking to prevent the merger, to rescind
the merger or to conditionally approve the merger upon the divestiture of
substantial assets of Sync or Entrada. There can be no assurance that a
challenge to the merger on antitrust grounds will not be made or, if such a
challenge is made, that it would not be successful.

    GENERAL.  It is possible that any of the governmental entities with which
filings are made may seek, as conditions for granting approval of the merger,
various regulatory concessions. There can be no assurance that:

    - Sync or Entrada will be able to satisfy or comply with such conditions

    - compliance or non-compliance will not have adverse consequences for Sync
      after completion of the merger

    - the required regulatory approvals will be obtained within the time frame
      contemplated by Sync and Entrada and referred to in this proxy
      statement/prospectus or on terms that will be satisfactory to Sync and
      Entrada.

    See "The Merger Agreement--Conditions to the Completion of the Merger."

RESALE OF SYNC COMMON STOCK

    Sync common stock issued in the merger to Parent will not be subject to any
restrictions on transfer arising under the Securities Act of 1933, except that,
because Parent is an "affiliate" of Sync under the Securities Act, the Sync
common stock issued to Parent as a result of the merger may be resold by Parent
only in transactions permitted by the resale provisions of Rule 144 under the
Securities Act or as otherwise permitted under the Securities Act. An affiliate
is defined generally as including, without limitation, directors, certain
executive officers and beneficial owners of 10% or more of a class of common
stock of a company.

      prior to the date on which the merger is to be completed

    - the other party having obtained all material orders, consents, approvals,
      permits, authorizations, notices, declarations, filings, applications,
      qualifications and registrations necessary to complete the merger or
      continue the business of the combined companies after the merger

    Sync can provide no assurance that all of the conditions precedent to the
merger will be satisfied or waived by the party permitted to do so. Sync cannot
at this point determine whether it would resolicit proxies in the event that it
decides to waive any of the items listed above. This decision would depend upon
the facts and circumstances leading to Sync's decision to complete the merger
and whether Sync believes there has been a material change in the terms of the
merger and its effect on Sync stockholders. In making its determination, Sync
would consider, among other factors, the reasons for the waiver, the effect of
the waiver on the terms of the merger, whether the requirement being waived was
necessary in order to make the deal fair to the stockholders from a financial
point of view, the availability of alternative transactions and the prospects of
Sync as an independent entity. If Sync determines that a waiver of a condition
would materially change the terms of the merger, including the expected
qualification of the merger as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code, it will resolicit proxies.

NO SOLICITATION

    The merger agreement provides that Sync, Parent and its subsidiaries, and
the officers, directors, employees or other agents of Sync, Parent and its
subsidiaries, will not, directly or indirectly:

    - take any action to solicit, initiate or encourage any takeover proposal,
      as described below

    - engage in negotiations with, or disclose any nonpublic information
      relating to Sync or Entrada to, or afford access to the properties, books
      or records of Sync or Entrada to, any person that has advised Sync,
      Entrada or Parent that it may be considering making, or that has made, a
      takeover proposal.

    The merger agreement further provides that the term "takeover proposal"
means any offer or proposal for, or any indication of interest in, a merger or
other business combination involving Sync or Entrada, or the acquisition of any
significant equity interest in, or a significant portion of the assets of, Sync
or Entrada, other than the merger contemplated by the merger agreement.

    Notwithstanding the restrictions described above, if an unsolicited takeover
proposal, or an unsolicited written expression of interest that can reasonably
be expected to lead to a takeover proposal, shall be received by the board of
directors of Sync or Parent, then, to the extent the board of directors of such
company believes in good faith (after consultation with its financial advisor)
that such takeover proposal would, if accepted, result in a transaction more
favorable to such company's stockholders from a financial point of view than the
merger contemplated by the merger agreement (any such more favorable takeover
proposal being referred to in the merger agreement as a "superior proposal"),
and the board of directors of such company determines in good faith after
consultation with outside legal counsel that it is necessary for such board of
directors to evaluate the superior proposal in order to comply with its
fiduciary duties to stockholders, such company and its officers, directors,
employees, investment bankers, financial advisors, attorneys, accountants and
other representatives retained by it may provide relevant information and take
such other actions as are consistent with the fiduciary obligations of its board
of directors, and such actions shall not violate the merger agreement; PROVIDED,
HOWEVER, that Sync and Parent shall not, and shall not permit any of their
respective officers, directors, employees or other representatives to, agree to
or endorse any takeover proposal regarding Sync or Entrada unless Sync or Parent
shall have

    - terminated the merger agreement; and

    - agreed to pay to the other party, without interest, the sum of $1,000,000
      no later than thirty days after the closing of the transaction resulting
      from the superior proposal.

    Each of Sync and Parent will promptly notify the other after receipt of any
takeover proposal or any notice that any person is considering making a takeover
proposal or any request for nonpublic information relating to Sync or Entrada or
for access to the properties, books or records of Sync or Entrada by any person
that has advised Sync or Parent that it may be considering making, or that has
made, a takeover proposal and will keep Sync or Parent, as applicable, fully
informed of the status and details of any such takeover proposal notice or
request.

      Parent to comply in all material respects with the agreements and
      covenants contained in the merger agreement to be performed by Entrada or
      Parent by August 31, 2000

    - by either Sync or Parent, if any court or governmental authority of
      competent jurisdiction shall have issued an order, decree or ruling or
      taken any other action restraining, enjoining or otherwise prohibiting the
      merger and such order, decree or ruling or other action shall have become
      final and nonappealable

    - by either Sync or Parent, upon (i) receipt of an unsolicited proposal that
      its board of directors determines in good faith to be superior to the
      merger and (ii) agreement to pay to the other party, without interest, the
      sum of $1,000,000 no later than thirty days after the closing of the
      transaction resulting from the superior proposal

Sync's bank line of credit prohibits Sync from paying cash dividends without the
bank's prior written consent. Any future determination to pay cash dividends
will be at the discretion of the board of directors and will be dependent upon
the combined companies' financial condition, results of operations, capital
requirements and such other factors as the board of directors deems relevant.

(a) On May 12, 2000, Sync completed a private placement of newly issued
    Series A Preferred Stock for an aggregate price of $2,235,625. All such
    shares will be automatically converted into Sync common stock upon the
    completion of the merger. Accordingly, the private placement, net of
    offering costs estimated to be approximately $175,000, has been reflected in
    the accompanying pro forma condensed consolidated balance sheet as if the
    transaction occurred at January 31, 2000.

 NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED BALANCE SHEET (CONTINUED)

B.  PRO FORMA ADJUSTMENTS (CONTINUED)
(b) The Agreement specifies that all of Entrada's outstanding common stock will
    be cancelled in exchange for shares of Sync common stock. The number of
    shares of Sync common stock to be issued in exchange for Entrada's
    outstanding common stock will equal the amount of shares of Sync common
    stock outstanding at closing. Based upon the number of shares outstanding on
    May 12, 2000, the date of the completion of the private placement discussed
    in footnote (a), the number of shares to be issued in connection with the
    merger would have been 4,231,007. The pro forma condensed consolidated
    balance sheet reflects the allocation of approximately $14.8 million to
    Sync's assets and liabilities based upon a value of $3.50 per share, the
    closing price of Sync's common stock on the Nasdaq National Market on
    May 12, 2000. The excess of the net book value of Sync's net assets as of
    the pro forma balance sheet date over such purchase price, approximately
    $0.5 million, has been reported as a reduction in the carrying value of
    furniture, fixtures and equipment.

    In connection with the merger, the outstanding intercompany payable from
    Entrada to Parent will be contributed by Parent as an equity contribution.
    This contribution has been reflected in the accompanying pro forma condensed
    consolidated balance sheet.

(c) Parent expects to incur direct transaction costs of approximately $200,000
    consisting primarily of legal and accounting costs. These direct costs have
    been included in the estimated purchase price reflected in the pro forma
    condensed consolidated balance sheet.

    Sync estimates it will incur direct transaction costs of approximately
    $700,000 associated with the merger, consisting primarily of fees for
    investment banking, filings with regulatory agencies, legal, accounting,
    financial printing and other related costs. These transaction costs will be
    expensed within the twelve month period following January 31, 2000 as they
    are incurred by Sync and have been reflected as a liability in the pro forma
    condensed consolidated balance sheet.

(d) Sync and Entrada expect to incur certain expenses in connection with the
    restructuring and consolidation of the operations of the consolidated
    companies including, but not limited to, costs related to the closure and
    elimination of duplicate leased facilities and write-offs of related fixed
    assets, write-off of discontinued products, and severance costs. Sync and
    Entrada anticipate that the ultimate integration activities will result in
    increased efficiencies and lower operating costs. These activities have not
    been formalized, therefore, the amount of such expenses is not currently
    estimable with a reasonable degree of accuracy. Accordingly, no liability
    for these expenses has been included in the unaudited pro forma condensed
    consolidated balance sheet.

                              SYNC RESEARCH, INC.

              NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED
                            STATEMENT OF OPERATIONS

    On April 10, 2000, Sync, Sync Research Acquisition Corp., a wholly-owned
subsidiary of Sync, Osicom Technologies, Inc., a New Jersey corporation
("Parent"), and Osicom Technologies, Inc., doing business as Entrada Networks, a
Delaware corporation and wholly-owned subsidiary of Parent ("Entrada" or
"Osicom"), entered into an Agreement and Plan of Merger (the "Agreement"). The
merger is expected to be accounted for as an acquisition of Sync by Entrada
using the purchase method of accounting.

A.  ACCOUNTING PERIODS

    The unaudited pro forma condensed consolidated financial statements include
the results of operations and financial position of Entrada and Sync for the
years ended and as of January 31, 2000 and December 31, 1999, respectively and
were derived from audited financial statements as of and for the fiscal year
ended January 31, 2000 and December 31, 1999, respectively.

B.  MERGER COSTS

    Parent expects to incur direct transaction costs of approximately $200,000
consisting primarily of legal and accounting costs. These direct costs have been
included in the purchase price allocation.

    Sync estimates it will incur direct transaction costs of approximately
$700,000 associated with the merger, consisting primarily of fees for investment
banking, filings with regulatory agencies, legal, accounting, financial printing
and other related costs. These non-recurring transaction costs will be expensed
as they are incurred by Sync and have been excluded from the pro forma condensed
consolidated statement of operations.

    Sync and Entrada expect to incur in the twelve months following the closing
of the merger, certain expenses in connection with the restructuring and
consolidation of the operations of the consolidated companies including, but not
limited to, costs related to the closure and elimination of duplicate leased
facilities and write-offs of related fixed assets, write-off of discontinued
products, and severance costs. Sync and Entrada anticipate that the ultimate
integration activities will result in increased efficiencies and lower operating
costs. These activities have not been formalized, therefore, the amount of such
expenses is not currently estimable with a reasonable degree of accuracy.
Accordingly, no estimate of such expense is reflected in the unaudited pro forma
condensed consolidated statement of operations.

C.  PRO FORMA ADJUSTMENTS

    The pro forma adjustments reflected in the condensed consolidated statement
of operations represent the amortization of a $343,000 reduction to the carrying
value of Sync's long-term assets, utilizing a 3 year estimated remaining useful
life, attributable to the excess of the net identifiable assets and liabilities
over the purchase price of Sync.

D.  EARNINGS PER SHARE

    The pro forma consolidated weighted average common share amounts reflected
in the unaudited pro forma condensed consolidated statements of operations
represent the aggregate of the historical weighted average common shares of Sync
outstanding during the year ended December 31, 1999 plus 4,231,007 shares
expected to be issued to Parent in connection with the merger, based upon the
number of shares outstanding on May 12, 2000 shares, 700,000 shares of common
stock to be issued in connection with the conversion of Sync's outstanding
Series A preferred stock which Sync issued in May 2000, and the dilutive effect,
if any, of common stock equivalents outstanding as calculated in accordance with
Statement of Financial Accounting Standards No. 128, Earnings per Share.

                              BUSINESS OF ENTRADA

DESCRIPTION OF BUSINESS

    Entrada, based in Annapolis Junction, Maryland, designs, manufactures and
markets products that provide access to and enhance the performance of data and
telecommunications networks, and is currently developing products that provide
connectivity for storage networks. Many of Entrada's products are incorporated
into the remote access and other server products of original equipment
manufacturers ("OEMs"). In addition, certain of Entrada's products are deployed
by telecommunications network operators, applications service providers,
internet service providers, and the operators of corporate local area and wide
area networks for the purpose of providing access to and transport within their
networks. Entrada was incorporated in Delaware in 1972, and it operates in one
business segment, with primary facilities in Annapolis Junction, Maryland and
Westborough, Massachusetts.

ENTRADA'S STRATEGIC PLAN

    - DEVELOP PRODUCTS FOR STORAGE AREA NETWORKS. One of the most rapidly
      growing segments of the market for networking equipment is the market for
      storage area networks. Storage area networks are used to provide data
      warehousing and clustering, remote backup, disaster recovery, near online
      storage and a variety of other operations on stored data that are better
      performed when that data is archived in locations physically near to
      users, or connected to users via optical networks. The industry standard
      for transmitting data to and within storage area networks is Fibre
      Channel, a protocol or format for transmitting data over copper wire or
      fiber optic cable. In 1999, Entrada began developing Fibre Channel
      products to address the needs of storage area networks. Entrada's first
      Fibre Channel and storage networking products are expected to be available
      for sale during the third quarter of calendar 2000. Entrada believes that
      it will be able to leverage its experience in data networking in order to
      develop and sell Fibre Channel products to the storage area networking
      market.

    - FOCUS ON LAN CONNECTIVITY PRODUCTS. Entrada's current products include
      network interface (or "adapter") cards which allow computers, servers,
      load balancers and other devices to connect to a local area network
      ("LAN"). These network interface cards generally support the widely-
      employed Fast Ethernet protocol, and have achieved acceptance among
      several of the server and other OEMs to whom Entrada plans to market and
      sell its Fibre Channel products. Entrada plans to focus its product
      offerings on its LAN adapters while it develops new products for the
      storage area networking market.

    - FOCUS ON ORIGINAL EQUIPMENT MANUFACTURERS (OEMS). Entrada currently sells
      its LAN products directly to OEMs, while its other networking products are
      generally sold to end-users through distributors and network systems
      integrators. In order to maintain the continuity of its relationships with
      its OEMs while it develops its Fibre Channel products, Entrada plans to
      continue to focus most of its sales and marketing efforts on the OEM
      channel.

MARKETS FOR ENTRADA'S PRODUCTS

    Entrada's products address the growing connectivity needs for networked,
high bandwidth data and voice communications. The networking industry has
experienced dramatic growth since the early 1990's as corporations discovered
increasing value in connecting desktop devices through local area networks. The
emergence of the Internet and the cultural movement toward wireless and home
computing in the 1990's further accelerated this trend. Entrada's products
address the demand for connectivity solutions in the traditional data networking
markets and the emerging market for storage area networking. There can be no
assurance that any of the projections cited in the following discussion
regarding the growth of traditional data networking markets or of the storage
area networking market will prove accurate,

                                       57
<PAGE>
and Sync stockholders should not rely on such projections in evaluating the
business of Entrada or the combined companies.

    STORAGE AREA NETWORKING MARKET

    The technology behind storage area networks is similar to that of LANs and
WANs. Storage area networks are essentially separate local area networks that
consist of servers, storage devices (such as disc drives) and the networking
equipment used to connect and route traffic among them. These devices include
adapters, hubs, switches and routers supporting the Fibre Channel standard.
Storage area networks create a shared storage resource that is readily
available, highly scalable and designed to be easily protected and managed.

    While storage area networks are not new, Entrada believes that trends
already under way will move them into the mainstream of distributed networking
and that they will become the standard way of accessing stored information. A
report by Dataquest, an Information Technology ("IT") market research and
consulting firm, projects sales of the networking equipment used to build
storage area networks to reach $1.8 billion by 2002, representing a cumulative
annual growth rate of 88%. Strategic Research, a market research firm
specializing on the storage and network storage markets, projects that storage
area networks will represent approximately 50% of all sales of non-mainframe
storage arrays (such as disc drives) in 2000. In addition, the S.G.
Cowen-Datamation 2000 Computer Systems User Survey, conducted by the securities
and investment banking firm of S.G. Cowen and EarthWeb's datamation.com, a
publication for the IT industry, reported that in 1999, 42% of all enterprises
surveyed were planning to deploy storage area networks.

    IDC (International Data Corporation), a provider of analysis and market data
for the IT industry, projects that the amount of disk storage capacity being
shipped by vendors will grow by 86% per year over the next three years, from
116,000 terabytes in 1998 to 1.4 million terabytes in 2002. IDC projects storage
capacity based on the UNIX operating system to grow 76% annually to nearly
460,000 terabytes in 2002 and storage capacity based on the Windows NT operating
system to increase by 114% annually to more than 610,000 terabytes in 2002. The
Yankee Group, a research and consulting firm which focuses on e-business, the
Internet, and enterprise applications, reports that storage is now the biggest
line item in the IT budgets of corporations interviewed.

ENTRADA'S PRODUCT DEVELOPMENT APPROACH

    The goal of any storage system is to allow users to retrieve information
quickly, easily and reliably. There are five major capabilities that a storage
solution must provide:

    - CONNECTIVITY. Storage systems must provide access to the data and
      applications that users need.

    - AVAILABILITY AND FAULT TOLERANCE. Storage systems must allow continuous
      access to their data, even if one or more components fail.

    - PERFORMANCE. Storage systems must provide high performance and be
      scalable.

    - INTEGRITY. Storage systems must protect their data to ensure its accuracy
      and reliability.

    - MANAGEABILITY. Network operators must be able to manage their storage
      systems using the traditional tools of network management (such as network
      management software).

    Entrada is designing its storage area networking to be in conformity with
these requirements.

                                       58

PRODUCTS

    FIBRE CHANNEL PRODUCTS

    Entrada's Fibre Channel products under development leverage its skills and
know-how gained from providing LAN and WAN connectivity to traditional data
networks. These products also address the same or similar OEM customer base for
Entrada's LAN products.

    Entrada is currently developing two product lines designed to meet the needs
of storage area networks, and it plans to introduce additional product lines in
the future. The first of these products are expected to be available for sale
during the third quarter of calendar 2000. Each of the two product lines under
current development supports the Fibre Channel protocol, which Entrada's believe
will become the standard protocol for storage area networks.

    FIBRE CHANNEL HOST BUS ADAPTERS

    Entrada is currently developing a family of Fibre Channel Host Bus Adapters
("HBA's") for the storage area networks market. HBA's are installed in servers
and workstations, and provide the interface to the Fibre Channel network in much
the same way as our LAN adapters provide an interface to the Ethernet network.
Entrada expects that its HBA product line will include 1 Gigabit and 2 Gigabit
per second data transfer rate products for a variety of computer bus types.

    FIBRE CHANNEL HUBS

    Entrada is also developing a family of Fibre Channel hubs, which are used
for insertion and removal of devices on a Fibre Channel loop and for efficient
network management. Entrada plans to offer both entry-level and managed models
in a variety of port configuration options. Entrada expects that its hub product
line will include 1 Gigabit and 2 Gigabit per second data transfer rates
products.

    LAN ADAPTERS

    In the fiscal year ended January 31, 2000, 52% of Entrada's revenues were
derived from the sale of its line of high performance Local Area Network adapter
cards to OEMs. These adapter cards are used in a variety of products, including
high availability telecommunications equipment, Transmission Control
Protocol/Internet Protocol ("TCP/IP") load balancing routers, and remote access
servers. Entrada's LAN adapters are also used in a variety of industrial control
applications. Entrada's key products in this category consist of 10/100 Fast
Ethernet Adapters in both Peripheral Component Interconnect ("PCI") Bus
Specification and PCI Mezzanine Card ("PMC") form factors or sizes.

    SERIES 2400 FAST ETHERNET ADPATERS

    The 2404 is a high performance, quad-port 10/100 adapter that provides four
separate Fast Ethernet ports on a single PCI card, extending the local bus with
a PCI-to-PCI bridge and reducing the PCI bus load. The product is based on the
widely-used Intel media access controller ("MAC") and provides 64-bit data
transfer.

    SERIES 2350 FAST ETHERNET ADAPTERS

    The 2350 PMC adapter provides a single 10/100 port in the convenient PMC
form factor. The PMC form factor allows the card to be used in systems that are
based on both the VME industrial bus standard and the emerging Compact PCI bus
standard. Since drivers can easily be ported between these formats, the cards
can be used commonly by system OEMs.

                                       59
<PAGE>
    SERIES 2450 FAST ETHERNET ADAPTERS

    Using the feature rich and power-efficient Intel MAC, both the single-port
2451 and dual-port 2452 adapter offer low-profile RJ-45 front panel connectors
which eliminate the need for transition cables. The 2450 series adapters fully
support IEEE 802.3u and are compatible with PCI-SIG v2.1 and PICMG v2.1.

    SERIES 2200 AND 2250 FIBER DISTRIBUTED DATA INTERFACE ("FDDI") ADAPTERS

    Entrada provides adapters for high-performance, high-reliability networking
using the FDDI protocol in the PCI (2200) and PMC (2250) form factors. Both
models are offered in single attach station and dual attach station versions,
and are available in a number of media and connector options. Entrada believes
that this product is in the final stages of its marketable life.

    GIGABIT ETHERNET ADAPTERS

    Entrada is developing a series of LAN Adapters that support the growing
market for Gigabit Ethernet connectivity. The 2500 Series Gigabit Ethernet
Adapters will provide 10/100/1000 Mbps data transmission speeds, which will
offer existing 10/100 customers a convenient migration path to Gigabit Ethernet.
Entrada plans to introduce dual port Gigabit Ethernet PCI adapters and single
port PMC adapters in both copper media (1000-TX) and multimode fiber media
(1000-SX) versions. These products are expected to be available for sale during
the third quarter of calendar 2000.

SALES AND MARKETING

    Entrada's sales organization at January 31, 2000 consisted of approximately
28 individuals, including managers, sales representatives, and support
personnel. Entrada's sales organization addresses the needs of customers by
focusing on major accounts and indirect channels. Major accounts includes
telecommunications service providers, internet service providers, government
customers and original equipment manufacturers. Entrada's indirect channels are
comprised of system integrators, distributors, resellers and value added
resellers. Entrada supports its customers by providing product training, regular
mailing of promotional and technical material, telephone and other technical
support.

    The goal of Entrada's marketing effort is to identify market dynamics and
translate these dynamics into strategic product development plans. Entrada's
marketing staff identifies product and vertical market segment opportunities and
provides to its sales force the tools, training, and pre-sales support it
requires to exploit the identified opportunities. Entrada's marketing staff also
engages in a number of marketing communication activities, and it participates
in cooperative marketing programs, including advertising, trade shows and
seminars.

CUSTOMERS AND MARKETS

    Entrada's customer base is concentrated in the telecommunications and
networking equipment industries. With the exception of two customers, none of
Entrada's customers has accounted for ten percent or more of its net sales. One
customer accounted for 19.4% of net sales for the year ended January 31, 2000
and 1.0% of net sales for the year ended January 31, 1999. This customer
accounted for 4.4% and 2.3% of net receivables at January 31, 2000 and
January 31, 1999, respectively. A second customer accounted for 13.7% of net
sales for the year ended January 31, 2000 and 1.3% of net sales for the year
ended January 31, 1999. This customer accounted for 8.6% and 0% of net
receivables at January 31, 2000 and January 31, 1999, respectively. Two
customers accounted for 39.4% and 9.6% of net receivables, respectively, at
January 31, 2000. These two customers accounted for 29.7% and 10.0% of net
receivables, respectively, at January 31, 1999. A third customer accounted for
18.7% of net sales for the year ended January 31, 2000 and 16.3% of net sales
for the year ended January 31, 1999. This customer accounted for 39.4% and 29.7%
of net receivables at January 31, 2000 and January 31, 1999,

                                       60
<PAGE>
respectively. Five customers represented 68% and 60% of accounts receivable at
January 31, 2000 and 1999, respectfully.

    Entrada's strategy addresses the following three customer profiles:

    - ORIGINAL EQUIPMENT MANUFACTURERS. Original Equipment Manufacturers
      ("OEMs") develop and sell solutions that incorporate Entrada LAN and WAN
      products to provide connectivity to networks, including storage area
      networks, local area networks and wide area networks. In addition to the
      revenues Entrada may achieve directly by having its connectivity solutions
      incorporated into the products of major networking OEMs, Entrada believes
      that the incorporation of its technology into the products of major
      networking OEMs can have an indirect positive impact on the adoption of
      Entrada's technology, and therefore the sales of its stand-alone products.

    - SERVICE PROVIDERS. These customers provide communication services and
      primarily include telecommunication carriers, applications service
      providers and internet service providers. Entrada believes that in the
      future, these service providers will add data storage to the
      telecommunications services they currently offer to their subscribers.

    - SYSTEM INTEGRATORS. Networks are frequently provided to enterprises by
      system integrators who bring together all of the technology pieces
      required to build a network, and who organize those pieces into a logical
      architecture. In the frequent instance that the selection of specific
      equipment types is made by the system integrator, the system integrator
      (and not the enterprise for which the network is being constructed) is the
      customer to vendors of network equipment.

CUSTOMER SERVICE AND SUPPORT

    Entrada's customer service organization is structured to assist both systems
integrators and its major OEM accounts. In addition to the product design,
integration and troubleshooting support Entrada supplies to its OEM customers,
it generally provides training and sales support to its system integrator
customers.

    Post-sales support for all of Entrada's customers includes its product
warranty against defects in material and workmanship. The length of product
warranties varies by product, from 12 months in some instances, to 60 months for
a broad range of products, and up to lifetime warranties for certain selected
products. Telephone technical support programs for hardware and software
generally cover the first 12 months from purchase. On-site support and shared
support agreements are designed to provide a high level of service to fulfill a
broad spectrum of customer needs.

RESEARCH AND DEVELOPMENT

    The goal of Entrada's research and development efforts is to achieve
technological advances which will allow it to introduce innovative products to
market. Product introduction is driven by a combination of rapidly evolving
technology and standards, as well as changing customer requirements. Entrada's
marketing staff works closely with its engineering staff, performing continuous
evaluations of customer needs, emerging trends and technical challenges in order
to identify new market opportunities. Entrada's research and development program
focuses on the combining of various proprietary technologies into a single,
common, standards-based platform. Entrada believes that its ability to introduce
new products on a timely basis depends upon its ability to maintain
sophisticated technology research programs while simultaneously focusing on
their practical application to its customers' strategic requirements.

    As of January 31, 2000, there were 21 employees and 12 independent
contractors working in Entrada's research and development area. Entrada's
research and development expenditures were

                                       61
<PAGE>
$6.2 million and $5.5 million for the fiscal years ended January 31, 2000 and
January 31, 1999, respectively.

MANUFACTURING AND QUALITY

    Entrada's products are manufactured on an outsourced basis by various
turn-key vendors. Final assembly, test and quality assurance are performed by
Entrada at its Annapolis Junction, Maryland facility.

    Entrada believes that its strategy of outsourcing the majority of its
manufacturing activities to third party contract manufacturers enables it to
react quickly to market demand and avoid the significant capital investment that
would be required to establish and maintain full manufacturing facilities.
Entrada is thus able to focus its manufacturing resources on final assembly,
burn-in and final testing to ensure reliability and quality assurance for its
products. Entrada has a quality assurance program in place and continually
evaluates its process to ensure quality practices throughout its organization
and to monitor the performance of its third party vendors.

AVAILABILITY OF RAW MATERIALS

    Many of Entrada's products require components which may not be readily
available. These include microprocessors, custom integrated circuits and other
electronic components. To minimize the risks of component or product shortages,
Entrada attempts to maintain multiple supply sources. However, there can be no
assurance that such sources will be adequate to meet Entrada's needs.

PATENTS, TRADEMARKS AND LICENSES

    Entrada currently hold nine patents. Although Entrada attempts to protect
its intellectual property rights through patents, trademarks, and copyrights, by
maintaining certain technology as trade secrets and by other measures, Entrada
cannot assure you that any patent, trademark, copyright or other intellectual
property rights owned by Entrada will not be invalidated, circumvented or
challenged; that such intellectual property rights will provide competitive
advantages to Entrada; or that any of Entrada's future patent applications, if
any, will be issued with the scope of the claims sought by Entrada, if at all.
Entrada cannot assure you that others will not develop technologies that are
similar or superior to its technology, or that its competitors will not
duplicate its technology or "design around" the patents that it owns. In
addition, effective patent, copyright and trade secret protection may be
unavailable or limited in certain foreign countries in which Entrada does
business or intends to do business in the future.

    Entrada believes that the future success of its business will depend on its
ability to translate the technological expertise and innovation of its personnel
into new and enhanced products. Entrada cannot assure you that the steps taken
by it will prevent misappropriation of its technology. In the future, Entrada
may take legal action to enforce its patents and other intellectual property
rights, to protect its trade secrets, to determine the validity and scope of the
proprietary rights of others, or to defend against claims of infringement or
invalidity. Such litigation could result in substantial costs and diversion of
resources and could harm its business and operating results.

    As is common in Entrada's industry, Entrada has from time to time received
notification from other companies claiming that certain Entrada products may
infringe intellectual property rights held by such companies. Any claim or
litigation, with or without merit, could be costly, time consuming and could
result in a diversion of management's attention, which could harm Entrada's
business. If Entrada were found to be infringing the intellectual property
rights of any third party, it could be subject to liabilities for such
infringement, which could be material, and could be required to seek licenses
from other companies or to refrain from using, manufacturing or selling certain
products or using certain processes. Although holders of patents and other
intellectual property rights often offer licenses to

                                       62
<PAGE>
their patent or other intellectual property rights, no assurance can be given
that licenses would be offered, that the terms of any offered license would be
acceptable to Entrada or that failure to obtain a license would not cause its
operating results to suffer.

SEASONALITY

    Entrada's sales are impacted by the buying patterns of its customers,
including but not limited to cultural and religious holidays in Asia, Europe and
the United States, and other factors.

WORKING CAPITAL PRACTICES

    Entrada has historically maintained high levels of inventories to meet the
output requirements of its customers and to ensure an uninterrupted flow of
inputs from its suppliers.

    Entrada performs ongoing credit evaluations of each of its customers'
financial condition and it extends unsecured credit related to the sales of
various products. Two customers accounted for 39.4% and 9.6% of net receivables,
respectively, at January 31, 2000. These two customers accounted for 29.7% and
10.0% of net receivables, respectively, at January 31, 1999. Five customers
represented 68% and 60% of accounts receivable at January 31, 2000 and 1999,
respectfully.

BACKLOG

    Entrada's backlog on January 31, 2000 was approximately $3.1 million
compared with an approximate backlog of $4.8 million at January 31, 1999.
Entrada includes in its backlog only orders confirmed with a purchase order for
products to be shipped within twelve months to customers with approved credit
status. Because of what has historically been a short time period between its
customers' orders and its shipments of products, and because its customers may
notify it of desired changes in delivery schedules or cancellations of orders
(which are made without significant penalty), Entrada does not believe that its
backlog, as of any particular date, is necessarily an indication of actual net
sales for any future period.

COMPETITION

    The markets for Entrada's current and planned products are intensively
competitive, highly fragmented and characterized by rapidly changing technology,
evolving industry standards, price competition and frequent new product
introductions. A number of companies offer products that compete with one or
more of its current or planned products. Entrada's current and prospective
competitors include OEMs, product manufacturers of internet access equipment,
remote access equipment, and LAN, WAN and storage area network equipment.
Regarding the market for storage area networking products, Entrada expects that
its competitors will include JNI Corporation, Emulex Corporation, Brocade
Communications Systems, Inc., Interphase Corporation, Gadzoox Networks, Inc.,
and others. In the LAN adapter area, Entrada competes with 3Com Corporation,

    Entrada has experienced, and expects to continue to experience, increased
competition from current and potential competitors, many of whom have
substantially greater financial, technical, sales, marketing and other
resources, as well as greater name recognition and larger customer based than
Entrada does. In particular, established companies in the telecommunications
equipment or computing industries may seek to expand their product offerings by
designing and selling products using competitive technology that could render
Entrada's products obsolete or have a material adverse effect on its sales. The
markets in which Entrada competes currently are subject to intense competition
and Entrada expects additional price and product competition as other
established and emerging companies enter the markets in which it is competing
and new products and technologies are introduced. Increased competition may
result in further price reductions, reduced gross margins and loss of market
share, any of which could materially and adversely affect its business,
operating results and financial condition. There can be no assurance that
Entrada will be able to compete successfully against current and future
competitors, or that the competitive factors it will face will not have a
material adverse effect on its business, operating results and financial
condition.

ENVIRONMENTAL COMPLIANCE

    Entrada's operations are subject to various federal, state and local laws
and regulations with respect to environmental matters. Entrada believes that it
is in material compliance with all such federal, state and local laws and
regulations.

EMPLOYEES

    As of January 31, 2000, Entrada employed 129 full-time employees and
independent contractors, including 33 in engineering, 35 in manufacturing and
quality assurance, 43 in sales, customer support and marketing, 17 in
administration, and 1 executive. None of Entrada's employees are represented by
a collective bargaining agreement, and it believes that relations with its
employees are good.

                  ENTRADA MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS: COMPARISON OF THE YEARS ENDED JANUARY 31, 2000 AND
  JANUARY 31, 1999

    NET SALES.  Net sales decreased to $28.8 million, or by less than 1%, for
fiscal 2000 from $29.0 million for fiscal 1999. While the sales to OEM's of our
LAN-adapter product lines increased, this increase was offset by the decrease in
the Remote Access and Print Server product lines during fiscal 2000 reflecting
Entrada's shift towards its new generation of products and the planned phase out
of its legacy products.

    GROSS PROFIT.  Cost of sales consists principally of the costs of
components, subcontract assembly from outside manufacturers, and in-house system
integration, quality control, final testing and configuration costs. Gross
profit decreased to $11.3 million, or 13.0%, for fiscal 2000 from $13.0 million
for fiscal 1999. Gross margin decreased to 39.2% for fiscal 2000 from 44.7% for
fiscal 1999. The gross margin percentage decrease was the result of higher raw
material costs associated with shipments of Entrada's LAN-adapter products and
lower margins on legacy products.

    SELLING AND MARKETING.  Selling and marketing expenses consist primarily of
employee compensation and related costs, commissions to sales representatives,
tradeshow expenses and travel expenses. Sales and marketing expenses decreased
to $5.6 million, or 19.6% of net sales, for fiscal 2000 from $8.3 million, or
28.7% of net sales for fiscal 1999. During the past fiscal year Entrada
completed a realignment of its sales organization, which resulted in a reduction
in these expenses as well as reduced advertising and promotional expenses for
legacy products.

    ENGINEERING, RESEARCH AND DEVELOPMENT.  Engineering, research and
development expenses consist primarily of compensation related costs for
engineering personnel, facilities costs, and materials used in the design,
development and support of our technologies as well as amortization of
capitalized software development costs. Engineering, research and development
expenses increased to $6.2 million, or 21.6% of net sales, for fiscal 2000 from
$5.5 million, or 19.0% of net sales, for fiscal 1999. The increase in
engineering, research and development expenses was the result of a $1.8 million
reduction to the net book value of capitalized software development costs caused
by changing market conditions partially offset by cost savings achieved through
the consolidation of Entrada's facilities. Exclusive of the valuation allowance,
engineering research and development expenses for fiscal 2000 were 15.3% of net
sales.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses consist
primarily of employee compensation and related costs, legal and accounting fees,
and allocable occupancy costs. General and administrative expenses decreased to
$2.2 million, or 7.6% of net sales, for fiscal 2000 from $2.3 million, or 7.8%
of net sales, for fiscal 1999. This decrease is the result of cost savings
achieved through the consolidation of Entrada's various facilities as well as
eliminating the 35,000 square feet of unused space leased at our Annapolis
Junction, Maryland facility.

    INCOME TAXES.  There was no provision for income taxes for fiscal years 2000
and 1999. We have carry forwards of domestic federal net operating losses, which
may be available, in part, to reduce future taxable income in the United States.
However, due to potential adjustments to the net operating loss carry forwards
as provided by the Internal Revenue Code with respect to future ownership
changes, future availability of the tax benefits is not assured. In addition, we
provided a valuation allowance in full for our deferred tax assets as it is our
opinion that it is more likely than not that some portion or all of the assets
will not be realized.

RESULTS OF OPERATIONS: COMPARISON OF THE YEARS ENDED JANUARY 31, 1999 AND
  JANUARY 31 1998

    NET SALES.  Net sales decreased to $29.0 million, or 5.3%, for fiscal 1999
from $30.6 million for fiscal 1998. This decrease was primarily the result of a
decline in the sales of Entrada's legacy products which was not fully offset by
introductions of Entrada's new generation of products.

    GROSS PROFIT.  Gross profit decreased to $13.0 million, or 4.4%, for fiscal
1999 from $13.6 million for fiscal 1998. Gross margin remained relatively
unchanged at 44.7% for fiscal 1999 and 44.3% for fiscal 1998. This decline in
gross profit is comparable to the decline in net sales.

    SELLING AND MARKETING.  Sales and marketing expenses decreased to
$8.3 million, or 28.7% of net sales, for fiscal 1999 from $9.0 million, or 29.3%
of net sales for fiscal 1998. This decrease was primarily the result of the
mid-fiscal year 1998 closure of the Santa Barbara, California facility.

    ENGINEERING, RESEARCH AND DEVELOPMENT.  Engineering, research and
development expenses increased to $5.5 million, or 19.0% of net sales, for
fiscal 1999 from $3.5 million, or 11.6% of net sales, for fiscal 1998. The
increase in engineering, research and development expenses was the result of
increased expenditures associated with continuing development of Entrada's
existing products and future technologies.

    GENERAL AND ADMINISTRATIVE.  General and administrative expenses decreased
to $2.3 million, or 7.8% of net sales, for fiscal 1999 from $3.6 million, or
11.8% of net sales, for fiscal 1998. This decrease is the result of cost savings
achieved through the consolidation of Entrada's various facilities as well as
other cost reduction programs implemented mid-fiscal year 1998.

    OTHER OPERATING EXPENSES.  Other operating expenses consist of
acquisition-related charges including amortization of purchased technology and
valuation allowances recorded against purchased technology. During fiscal 1998
other operating expenses including amortization of $123,000 and a valuation
allowance of $3.8 million. Certain of Entrada's products, primarily LAN related
items, were not competitive in the market for such products as the technology
desired by customers could not be cost-effectively added to such products.
Entrada re-aligned its resources to focus on providing integrated networking and
bandwidth aggregation products desired by customers. Accordingly, Entrada
recorded a valuation allowance against purchased technology that had no future
alternative use.

    INCOME TAXES.  There was no provision for income taxes for fiscal years 1999
and 1998. We have carry forwards of domestic federal net operating losses, which
may be available, in part, to reduce future taxable income in the United States.
However, due to potential adjustments to the net operating loss carry forwards
as provided by the Internal Revenue Code with respect to future ownership
changes, future availability of the tax benefits is not assured. In addition, we
provided a valuation allowance in full for our deferred tax assets as it is our
opinion that it is more likely than not that some portion or all of the assets
will not be realized.

LIQUIDITY AND CAPITAL RESOURCES

    Entrada finances its operations through a combination of debt and
non-interest bearing advances from its parent. At January 31, 2000, Entrada's
working capital was $4.2 million including $112,000 in cash.

    Operating activities provided cash flows of $134,000 during fiscal 2000 as
compared to a cash flow deficit of $2.8 million during fiscal 1999. The decrease
in cash flows used in operations reflects a substantial decline in our net loss,
after adjustment for non-cash expenses including depreciation, amortization,
reserves and valuation allowances, partially offset by fiscal 2000 investments
in inventory. During fiscal 1999 the operating cash flow deficit reflected an
increase in accounts receivable including amounts due from affiliates, a decline
in accounts payable and a decline in accrued expenses. Entrada's operating cash
flow deficit for fiscal 1998 of $3.7 million reflects a greater net loss, after
adjustment for

                                       66
<PAGE>
non-cash operating expenses, as well as substantial increases in accounts
receivable and inventories offset, in part, by increases in current liabilities.

    Our standard payment terms are net 30 days. Receivables from distribution
customers have frequently taken longer to collect.

    Entrada's investing activities consist of purchases of property and
equipment and software development costs. During fiscal 2000 Entrada purchased
equipment of $239,000 and invested $318,000 in software development as compared
with fiscal 1999 equipment purchases of $567,000 and software development of
$1.3 million. Investing activities during fiscal 1998 were comparable to those
of fiscal 1999.

    Entrada's financing activities during fiscal 2000 provided cash flows of
$337,000 which consisted of $2.3 million of non-interest bearing advances from
Osicom partially offset by net repayments of short and long term debt of
$1.9 million. During fiscal 1999 financing activities provided cash flows of
$4.6 million which consisted primarily of non-interest bearing advances from
Osicom. During fiscal 1998 financing activities provided cash flows of
$5.9 million which consisted of $3.2 million in advances from Osicom with the
remaining amounts received from short and long term financing.

    At January 31, 2000 the balance due Osicom was $21.8 million. The merger
agreement entered into by Osicom provides that amounts owed by Entrada to Osicom
at closing will be contributed to the capital of Entrada and no remaining debt
will be outstanding to Osicom after the merge.

    Entrada has a $7.0 million line of credit provided by Coast Business Credit,
a division of Southern Pacific Bank, an asset-based lender. Outstanding
short-term borrowings against this line of credit were $2.3 million at
January 31, 2000. This credit line is collateralized by accounts receivable,
inventory and equipment.

YEAR 2000 COMPLIANCE

    We have not experienced any year 2000 compliance problems to date and we
believe our products are year 2000 compliant. We are not aware that any of our
customers, vendors or contract manufacturers that have experienced any such
problems to date. It is possible that yet undiscovered problems could severely
disrupt our operations and would adversely affect our business if not properly
addressed.

EFFECTS OF INFLATION AND CURRENCY EXCHANGE RATES

    We are exposed to financial market risks, including changes in interest
rates and foreign currency rates. Our exposure to interest rate risk is the
result of our need for periodic additional financing for our large operating
losses and capital expenditures associated with establishing and expanding our
operations. The interest rate that we will be able to obtain on debt financing
will depend on market conditions at that time, and may differ from the rates we
have secured on our current debt. Additionally, the interest rates charged by
our present lender adjusts on the basis of the lenders' prime rate.

    We believe that the relatively moderate rate of inflation in the United
States over the past few years and the relatively stable interest rates incurred
on short-term financing have not had a significant impact on our sales,
operating results or prices of raw materials. There can be no assurance,
however, that inflation or an upward trend in short-term interest rates will not
have a material adverse effect on our operating results in the future should we
require debt financing in the future.

    All of our sales and expenses have been denominated in U.S. dollars and to
date our business has not been significantly affected by currency fluctuations.
However, we conduct business in several different countries and thus
fluctuations in currency exchange rates could cause our products to become
relatively more expensive in particular countries, leading to a reduction in
sales in that country.

                                       67
<PAGE>
In addition, inflation in such countries could increase our expenses. In the
future, we may engage in foreign currency denominated sales or pay material
amounts of expenses in foreign currencies and, in such event, may experience
gains and losses due to currency fluctuations. Our operating results could be
adversely affected by such fluctuations.

    We do not hold or issue derivative, derivative commodity instruments or
other financial instruments for trading purposes. Investments held for other
than trading purposes do not impose a material market risk.

IMPACT OF RECENT ACCOUNTING PRONOUNCEMENTS

    Statement of Financial Accounting Standards ("SFAS") No. 133, "Accounting
for Derivative Instruments and Hedging Activities," is effective for financial
statements with fiscal quarters of all fiscal years beginning after June 15,
2000. The Accounting Standards Executive Committee issued Statement of Position
("SOP") 98-1, "Accounting for the Costs of Computer Software Developed or
Obtained for Internal Use," and SOP 98-5, "Reporting on the Costs of Start-up
Activities," effective in the current or future periods. The adoption or future
adoption of these standards has had or will have no material effects, if any, on
our financial position or results of operations.

    BOARD MEETINGS AND COMMITTEES

    The board of directors held a total of seven (7) meetings during the fiscal
year ended December 31, 1999. The board of directors has an Audit Committee and
a Compensation Committee. It does not have a nominating committee or a committee
performing the functions of a nominating committee.

    During 1999, the Audit Committee of the board of directors consisted of
Charles A. Haggerty and William J. Schroeder, both of whom were non-employee
directors of Sync. The Audit Committee participated in several meetings during
1999, including meetings with Sync's management to review audited and interim
financial statements, independent auditor findings, accounting policies and
adequacy of internal controls.

    During 1999, the Compensation Committee of the board of directors consisted
of Charles Haggerty and William J. Schroeder, both of whom were non-employee
directors. The Compensation Committee participated in several meetings during
1999. The Compensation Committee, in conjunction with the board of directors,
establishes salaries, incentives and other forms of compensation for directors,
officers and other employees, administers the various incentive compensation and
benefit plans (including Sync's stock purchase and stock option plans) and
recommends policies relating to such plans. The Compensation Committee has
exclusive authority to award grants of options or restricted stock to executive
officers of Sync, pursuant to the 1991 Stock Plan and the 1995 Employee Stock
Purchase Plan.

    During 1999, no incumbent director attended fewer than 75% of the aggregate
number of meetings of the board of directors and of the committees of the board
of directors on which he serves.

                                       70
<PAGE>
    COMPENSATION OF DIRECTORS

    Mr. Reyes, the Chairman of the board of directors, earned $68,000 ($6,000
per month through October 1999 and $4000 per month thereafter) during 1999
pursuant to a consulting agreement with Sync. Non-employee directors are paid a
fee of $5,000 per quarter plus $1,000 for each full meeting of the board of
directors attended by such director. Directors are reimbursed for out-of-pocket
travel expenses associated with their attendance at board meetings. Non-employee
directors of Sync will automatically be granted options to purchase shares of
Sync common stock pursuant to the terms of the 1995 Directors' Stock Option Plan
(the "Directors' Plan"). Under the Directors' Plan, each non-employee director
who is elected to the board will receive an option to purchase 8,000 shares of
common stock on the date on which he or she first becomes a non-employee
director. In addition, on the date of each annual stockholders meeting, each
non-employee director, will be granted an additional option to purchase 2,000
shares of common stock if, on such date, he or she has served on the board for
at least six months and remains a director as of the date of such meeting. Each
option becomes exercisable at the rate of 25% of the total number of shares
subject to such option on the first anniversary of the grant date, and 1/48(th)
of the total number shares at the end of each month thereafter. Options granted
under the Directors' Plan have an exercise price equal to the fair market value
of Sync common stock on the date of grant and a term of ten years.
Messrs. Haggerty and Schroeder each received options to purchase 2,000 shares
pursuant to the Directors' Plan in 1999. Subject to his election to the board of
directors by the stockholders at the annual meeting, Mr. Haggerty will be
automatically granted an option to purchase 2,000 shares of common stock on the
date of the annual meeting. Subject to the authorization by the stockholders at
the annual meeting of the issuance of Sync common stock under the merger
agreement, Mr. Schroeder will not receive an option to purchase 2,000 shares of
common stock on the date of the annual meeting, as he will resign from the board
following the merger. There are no family relationships among the directors or
executive officers of Sync.

POTENTIAL NEW DIRECTORS

    If the Sync stockholders authorize the issuance of Sync common stock
pursuant to the merger agreement for completion of the merger, the board of
directors of Sync following the merger intends to increase the number of
directors who sit on the board from four to five, and to appoint Kanwar J.S.
Chadha, currently the President of Entrada and the intended Chief Executive
Officer of Sync following the merger, to fill such created vacancy. Further, it
is the present intention of Sync and Entrada to have Messrs. Guerry and
Schroeder step down from the board upon consummation of the merger, and be
replaced by Leonard N. Hecht, currently a director of Parent, and Rohit
Phansalkar, currently a director of Parent and a partner of Andersen Weinroth &
Co. LP, affiliates of which own all of the outstanding Series A Preferred Stock
of Sync and are stockholders of Parent. Therefore, assuming that the Sync
stockholders authorize the issuance of Sync common stock under the merger

PROPOSAL NO. 3: APPROVAL OF AMENDMENT TO THE 1995 EMPLOYEE STOCK PURCHASE PLAN

    At the annual meeting, stockholders are being asked to approve an amendment
to the 1995 Employee Stock Purchase Plan to increase the number of shares of
common stock reserved for issuance thereunder by 100,000 shares to an aggregate
of 140,000 shares, for which stockholder approval is being requested.

    GENERAL

    Sync's 1995 Employee Stock Purchase Plan was adopted by the board of
directors in August 1995 and was approved by Sync's stockholders in
November 1995. On May 9, 2000 the board of directors approved an amendment to
increase the number of shares reserved for issuance under the 1995

                                       72
<PAGE>
Employee Stock Purchase Plan by 100,000 shares to a total of 140,000 shares, for
which stockholder approval is being requested.

    The 1995 Employee Stock Purchase Plan, as amended, provides for the granting
to employees (including officers and employee directors) of stock purchase
rights within the meaning of Section 423 of the Internal Revenue Code of 1986,
as amended. See "United States Federal Income Tax Information" below for
information concerning the tax treatment of incentive stock purchase rights.

    As of May 3, 2000, 40,000 shares had been issued under the 1995 Employee
Stock Purchase Plan and no shares remained available for future purchase.

    The 1995 Employee Stock Purchase Plan is not a qualified deferred
compensation plan under Section 401(a) of the Internal Revenue Code, and is not
subject to the provisions of the Employee Retirement Income Security Act of
1974, as amended.

    The board of directors believes that in order to afford eligible individuals
whose present and potential contributions are important to the continued success
of Sync an opportunity to acquire a proprietary interest in Sync and to enable
Sync to continue to attract and retain the best available talent for the
successful conduct of its business in a competitive marketplace, it is necessary
to amend the 1995 Employee Stock Purchase Plan to reserve an additional 100,000
shares of common stock for issuance thereunder. The increase sought at the
annual meeting is expected to provide sufficient additional stock to continue
Sync's policy of using equity incentives to attract and retain the services of
key individuals essential to Sync's long-term success.

    PURPOSE

    The purpose of the 1995 Employee Stock Purchase Plan is to provide employees
of Sync the opportunity to purchase Sync common stock.

    ADMINISTRATION

    The board of directors, or a committee named by the board of directors,
shall supervise and administer the 1995 Employee Stock Purchase Plan and shall
have full power to adopt, amend and rescind any rules deemed desirable and
appropriate for, and not inconsistent with, the administration of the 1995
Employee Stock Purchase Plan, to construe and interpret the 1995 Employee Stock
Purchase Plan, and to make all other determinations necessary or advisable for
the administration of the 1995 Employee Stock Purchase Plan. The composition of
the committee shall be in accordance with the requirements to obtain or retain
any available exemption from the operation of Section 16(b) of the Exchange Act
pursuant to Rule 16b-3 promulgated thereunder.

    ELIGIBILITY

    Any person who is an employee of Sync shall be eligible to participate in
the 1995 Employee Stock Purchase Plan, subject to the limitations imposed by
Section 423(b) of the Internal Revenue Code. Any provisions of the 1995 Employee
Stock Purchase Plan to the contrary notwithstanding, no employee shall be
granted an option under the 1995 Employee Stock Purchase Plan (i) if,
immediately after the grant, such employee (or any other person whose stock
would be attributed to such employee pursuant to Section 424(d) of the Internal
Revenue Code) would own stock and/or hold outstanding options to purchase stock
possessing five percent (5%) or more of the total combined voting power or value
of all classes of stock of Sync or of any subsidiary of Sync, or (ii) if such
option would permit his or her rights to purchase stock under all employee stock
purchase plans (described in Section 423 of the Code) of Sync and its
subsidiaries to accrue at a rate which exceeds Twenty-Five Thousand Dollars
($25,000) of fair market value of such stock (determined at the time such option
is granted) for each calendar year in which such option is outstanding at any
time.

                                       73
<PAGE>
    OFFERING PERIODS; PARTICIPATION

    The 1995 Employee Stock Purchase Plan shall be implemented by a series of
offering periods, with new offering periods commencing on or about February 1
and August 1 of each year (or at such other time or times as may be determined
by the board of directors). An eligible employee may become a participant in the
1995 Employee Stock Purchase Plan by completing a subscription agreement on the
form provided by Sync and filing it with the payroll office prior to the
applicable offering date of each offering period.

    METHOD OF PAYMENT OF CONTRIBUTIONS

    The participant shall elect to have payroll deductions made on each payday
during the offering period in an amount not less than one percent (1%) and not
more than five percent (5%) of such participant's compensation on each such
payday. All payroll deductions made by a participant shall be credited to his or
her account under the 1995 Employee Stock Purchase Plan. A participant may not
make any additional payments into such account. A participant, on one occasion
only during the offering period, may decrease the rate of his or her
contributions during the offering period by completing and filing with Sync a
new subscription agreement. Notwithstanding the foregoing, to the extent
necessary to comply with the Internal Revenue Code and the eligibility
requirements under the 1995 Employee Stock Purchase Plan, a participant's
payroll deductions may be decreased to 0% at such time during any offering
period which is scheduled to end during the current calendar year that the
aggregate of all payroll deductions accumulated with respect to such offering
period and any other offering period ending within the same calendar year equals
or exceeds $21,250.

    GRANT OF OPTION

    On the commencement date of each offering period, each eligible employee
participating in such offering period shall be granted an option to purchase on
the exercise date a number of shares of Sync common stock determined by dividing
such employee's contributions accumulated prior to such exercise date by the
lower of (i) eighty-five percent (85%) of the fair market value of a share of
Sync common stock on the offering date, or (ii) eighty-five percent (85%) of the
fair market value of a share of Sync common stock on the exercise date. The
maximum number of shares an employee may purchase during each offering period
shall be determined at the offering date by dividing $12,500 by the fair market
value of a share of Sync common stock on the offering date.

    The fair market value of Sync common stock on a given date shall be
determined by the board of directors in its discretion based on the closing
price of Sync common stock for such date, as reported by the National
Association of Securities Dealers Automated Quotation (Nasdaq) National Market
or, if such price is not reported, the mean of the bid and asked prices per
share of Sync common stock as reported by Nasdaq.

    EXERCISE OF OPTION

    Unless a participant withdraws from the 1995 Employee Stock Purchase Plan,
his or her option for the purchase of shares will be exercised automatically on
the exercise date of the offering period, and the maximum number of full shares
subject to the option will be purchased at the applicable option price with the
accumulated contributions in his or her account. The shares purchased upon
exercise of an option hereunder shall be deemed to be transferred to the
participant on the exercise date. During his or her lifetime, a participant's
option to purchase shares hereunder is exercisable only by him or her.

    WITHDRAWAL; TERMINATION OF EMPLOYMENT

    A participant may withdraw all but not less than all of the contributions
credited to his or her account under the 1995 Employee Stock Purchase Plan at
any time prior to the exercise date of the

                                       74
<PAGE>
offering period by giving written notice to Sync. All of the participant's
contributions credited to his or her account will be paid to him or her promptly
after receipt of his or her notice of withdrawal and his or her option for the
current period will be automatically terminated, and no further contributions
for the purchase of shares will be made during the offering period.

    Upon termination of the participant as a Sync employee prior to the exercise
date of the offering period for any reason, including retirement or death, the
contributions credited to his or her account will be returned to him or her or,
in the case of his or her death, to the person or persons entitled previously
designated by the participant, and his or her option will be automatically
terminated. In the event an employee fails to remain in continuous status as an
employee of Sync for at least twenty (20) hours per week during the offering
period in which the employee is a participant, he or she will be deemed to have
elected to withdraw from the 1995 Employee Stock Purchase Plan and the
contributions credited to his or her account will be returned to him or her and
his or her option terminated.

    ADJUSTMENT UPON CHANGES IN CAPITALIZATION OR CORPORATE TRANSACTIONS

    CHANGES IN CAPITALIZATION.  If any change is made in the shares subject to
the 1995 Employee Stock Purchase Plan or subject to any option granted under the
1995 Employee Stock Purchase Plan, through merger, consolidation,
reorganization, recapitalization, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or otherwise, the board of directors shall
make appropriate adjustments as to the maximum number of shares subject to the
1995 Employee Stock Purchase Plan, the number of shares covered by any option
grant, the maximum number of shares issuable to employees, and the number of
shares and price per share covered by outstanding options.

    CORPORATE TRANSACTIONS.  In the event of the proposed dissolution or
liquidation of Sync, the offering period will terminate immediately prior to the
consummation of such proposed action, unless otherwise provided by the board. In
the event of a proposed sale of all or substantially all of the assets of Sync,
or the merger of Sync with or into another corporation, each option under the
1995 Employee Stock Purchase Plan shall be assumed or an equivalent option shall
be substituted by such successor corporation or a parent or subsidiary of such
successor corporation, unless the board determines, in the exercise of its sole
discretion and in lieu of such assumption or substitution, to shorten the
offering period then in progress by setting a new exercise date. If the board
shortens the offering period then in progress in lieu of assumption or
substitution in the event of a merger or sale of assets, the board shall notify
each participant in writing, at least ten (10) days prior to the new exercise
date, that the exercise date for his or her option has been changed to the new
exercise date and that his or her option will be exercised automatically on the
new exercise date, unless prior to such date he or she has withdrawn from the
offering.

    AMENDMENT OR TERMINATION

    The board of directors may at any time terminate or amend the 1995 Employee
Stock Purchase Plan. Except as otherwise provided in the plan, no such
termination may affect options previously granted, nor may an amendment make any
change in any option theretofore granted which adversely affects the rights of
any participant. In addition, to the extent necessary to comply with Rule 16b-3
under the Exchange Act, or with Section 423 of the Code, Sync shall obtain
stockholder approval in such a manner and to such a degree as so required.
Without stockholder consent and without regard to whether any participant rights
may be considered to have been adversely affected, the board (or its committee)
shall be entitled to change the offering periods, limit the frequency and/or
number of changes in the amount withheld during an offering period, establish
the exchange ratio applicable to amounts withheld in a currency other than U.S.
dollars, permit payroll withholding in excess of the amount designated by a
participant in order to adjust for delays or mistakes in Sync's processing of

                                       75
<PAGE>
properly completed withholding elections, establish reasonable waiting and
adjustment periods and/or accounting and crediting procedures to ensure that
amounts applied toward the purchase of Sync common stock for each participant
properly correspond with amounts withheld from the participant's compensation,
and establish such other limitations or procedures as the board (or its
committee) determines in its sole discretion advisable which are consistent with
the 1995 Employee Stock Purchase Plan.

    FEDERAL INCOME TAX ASPECTS OF THE 1995 EMPLOYEE STOCK PURCHASE PLAN

    The following is a brief summary of the United States federal income tax
consequences of transactions under the 1995 Employee Stock Purchase Plan based
on federal income tax laws in effect as of the date of this proxy statement
(which laws could change at any time hereafter). This summary is not intended to
be exhaustive and does not discuss the tax consequences of a participant's death
or provisions of the income tax laws of any municipality, state or other country
in which an optionee may reside. This summary does not purport to be complete.
Sync advises all participants to consult their own tax advisors concerning tax
implications of option grants and exercises, and the disposition of shares
acquired upon such exercises, under the 1995 Employee Stock Purchase Plan.

    The 1995 Employee Stock Purchase Plan, and the right of participants to make
purchases thereunder, is intended to qualify under the provisions of Sections
421 and 423 of the Code. Under these provisions, no income will be taxable to a
participant at the time of grant of the option or purchase of shares. Upon
disposition of the shares, the participant will generally be subject to tax, and
the amount of the tax will depend upon how long the participant has held the
shares. If the shares have been held by the participant for more than two years
after the date of option grant and one year after the date of purchase, the
participant will recognize ordinary income measured as the lesser of (a) the
excess of the fair market value of the shares at the time of such disposition
over the purchase price, or (b) an amount equal to 15% of the fair market value
of the shares as of the first day of the offering period. Any additional gain
will be treated as long-term capital gain, taxed at a maximum rate of 20% if the
shares are held for more than one year after the date of purchase. If the shares
are disposed of before the expiration of these holding periods, the excess of
the fair market value of the shares on the exercise date over the option price
will be treated as ordinary income, and any further gain or loss on such
disposition will be long-term or short-term capital gain or loss, depending on
whether or not the shares are disposed of more than one year after the date of
purchase. Sync is not entitled to a deduction for amounts taxed as ordinary
income or capital gain to a participant except to the extent of ordinary income
reported by participants upon disposition of shares prior to the expiration of
the holding periods described above.

    REQUIRED VOTE

    The affirmative vote of the holders of a majority of the shares of Sync
common stock present at the annual meeting in person or by proxy and entitled to
vote is required to approve the amendment to the 1995 Employee Stock Purchase
Plan to reserve an additional 100,000 shares of common stock for issuance
thereunder.

    THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE FOR THE APPROVAL OF THE
AMENDMENT TO THE 1995 EMPLOYEE STOCK PURCHASE PLAN TO RESERVE AN ADDITIONAL
100,000 SHARES OF COMMON STOCK FOR ISSUANCE THEREUNDER.

forward-looking statements. These risks and uncertainties include:

    - the possibility that the merger will not be consummated

    - the possibility that the anticipated benefits from the merger cannot be
      fully realized

    - the possibility that costs or difficulties related to the integration of
      our businesses are greater than expected

    - our dependence on the timely development, introduction and customer
      acceptance of new products

    - the impact of competition on revenues and margins

    - rapidly changing technology and shifting demand requirements

    - other risks and uncertainties, including the risks and uncertainties
      involved in obtaining new customers, the impact of competitive services,
      products and prices, the unsettled conditions in the high-technology
      business and the ability to attract and retain key personnel

    - other risk factors as may be detailed from time to time in Sync's and
      Entrada's public announcements and filings with the Securities and
      Exchange Commission.

    In evaluating the merger, you should carefully consider the discussion of
these and other factors in the section entitled "Risk Factors" on page 15 of

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

The Shareholder of
Osicom Technologies, Inc.

    We have audited the accompanying balance sheets of Osicom
Technologies, Inc. (a Delaware corporation, f/k/a Cray Communications, Inc.,
doing business as Entrada Networks) ("Entrada"), a wholly-owned subsidiary of
Osicom Technologies, Inc. (a New Jersey corporation), as of January 31, 2000 and
1999 and the related statements of operations, stockholder's deficit, and cash
flows for each of the years ended January 31, 2000, 1999 and 1998. These
financial statements are the responsibility of Entrada's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.

    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe our audits provide a reasonable basis for our opinion.

    In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Entrada as of January 31,
2000 and 1999, and the results of its operations and its cash flows for each of
the years ended January 31, 2000, 1999 and 1998 in conformity with generally
accepted accounting principles.

                      (IN THOUSANDS, EXCEPT SHARE AMOUNTS)

    Entrada Networks (the "Company," "We," "Our," or "Us") designs,
manufactures, and markets products that provide access to and enhance the
performance of data and telecommunications networks, and is currently developing
products that provide connectivity for storage networks. Many of our products
are incorporated into the remote access and other server products of original
equipment manufacturers ("OEMs"). In addition, certain of our products are
deployed by telecommunications network operators, applications service
providers, internet service providers, and the operators of corporate local area
and wide area networks for the purpose of providing access to and transport
within their networks. We have our facility in Annapolis Junction, Maryland. In
addition, we have various sales offices located in the United States. We market
and sell our products and services directly to end users as well as through a
broad array of channels including system integrators, worldwide distributors,
value added resellers, original equipment manufacturers ("OEM's"),
telecommunication service providers and governmental agencies.

    The accompanying financial statements are the responsibility of the
management of the Company.

A.  THE COMPANY AND BASIS OF PRESENTATION

    The Company, incorporated in Delaware in 1972, became a wholly owned
subsidiary of Osicom Technologies, Inc. ("Osicom" or "Parent") effective
June 30, 1996 in a transaction accounted for as a purchase in which the book
values of our assets and liabilities were adjusted to reflect their then market
value. During the periods covered by the financial statements, we operated as an
integral part of Osicom's overall operations and separate financial statements
were not prepared. These financial statements have been prepared from Osicom's
historical accounting records. The statements of operations may not be
indicative of the results of operations that would have resulted had we operated
as a stand-alone entity.

    General and administrative expenses include, in addition to amounts incurred
by us, an amount that management considers to be a reasonable allocation of
general corporate expenses. Management and administrative salaries are allocated
based upon estimated time; all other allocations of general corporate expenses
were based upon specific identification of the relationship of our operations to
the total operations of Osicom. Management believes that such allocated general
expenses are representative of the expenses we will incur as a separate public
company, however, actual expenses may be higher or lower. Included in general
and administrative expenses are $220, $182 and $160 of allocated corporate
expenses for the fiscal years 2000, 1999, and 1998, respectively.

    On April 11, 2000, Osicom entered into an agreement with Sync
Research, Inc. ("Sync"), a Nasdaq listed company, to exchange 100% of our
outstanding stock for a 50% interest in the merged corporation to be known as
Entrada Networks, Inc. The merger is subject to the approval of Sync's
shareholders and is expected to occur prior to September 2000.

B.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

    USE OF ESTIMATES--The preparation of financial statements in conformity with
generally accepted accounting principles requires us to make estimates that
affect the reported amounts of assets, liabilities, revenues and expenses, the
disclosure of contingent assets and liabilities and the values of purchased
assets. Actual results could differ from these estimates.

B.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    ACCOUNTS RECEIVABLE--In the normal course of business, we extend unsecured
credit to our customers related to the sales of various products. Typically
credit terms require payment within thirty days from the date of shipment. We
evaluate and monitor the creditworthiness of each customer on a case-by-case
basis.

    ALLOWANCE FOR DOUBTFUL ACCOUNTS--We provide an allowance for doubtful
accounts based on our continuing evaluation of our customers' credit risk. We
generally do not require collateral from our customers.

    INVENTORY--Inventory, comprised of raw materials, work in process, finished
goods and spare parts, are stated at the lower of cost (first-in, first-out
method) or market. Inventories at January 31, 2000 and 1999 consist of:

</TABLE>

    FAIR VALUE OF FINANCIAL INSTRUMENTS--The fair value of financial instruments
is determined by reference to various market data and other valuation techniques
as appropriate. We believe that there are no material differences between the
recorded book values of our financial instruments and their estimated fair value

    PROPERTY AND EQUIPMENT--Property and equipment are recorded at historical
cost. Depreciation and amortization are provided over the estimated useful lives
of the individual assets or the terms of the leases if shorter using accelerated
and straight-line methods. Useful lives for property and equipment range from 3
to 7 years.

    Capitalized leases are initially recorded at the present value of the
minimum payments at the inception of the contracts, with an equivalent liability
categorized as appropriate under current or non-current liabilities. Such assets
are depreciated on the same basis as described above. Interest expense, which
represents the difference between the minimum payments and the present value of
the minimum payments at the inception of the lease, is allocated to accounting
periods using a constant rate of interest over the lease.

    Property and equipment are reviewed for impairment whenever events or
circumstances indicate that the asset's undiscounted expected cash flows are not
sufficient to recover its carrying amount. We measure impairment loss by
comparing the fair market value, calculated as the present value of expected
future cash flows, to its net book value. Impairment losses, if any, are
recorded currently.

B.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    SOFTWARE DEVELOPMENT--Software development costs where technological
feasibility has not been established are expensed in the period in which they
occurred, otherwise, development costs that will become an integral part of our
products are deferred in accordance with Statement of Financial Accounting
Standards Nos. 2 and 86. The deferred costs are amortized using the
straight-line method over the remaining estimated economic life of the product
or the ratio that current revenues for the product bear to the total of current
and anticipated future revenues for that product. Amortization expense for the
years ended January 31, 2000, 1999 and 1998 was $1,043, $668 and $7,
respectively, over 3 to 5 years. Accumulated amortization was $727 and $675 as
of January 31, 2000 and 1999, respectively.

    The recoverability of capitalized software costs are reviewed on an ongoing
basis primarily based upon projections of discounted future operating cash flows
from each software product line. The excess amount, if any, of the remaining net
book value over the calculated amount is fully reserved. During the quarter
ended January 31, 2000 we recorded a reduction to the net book value of our
capitalized software development costs of $1,818, recorded as engineering
expense, to reflect the decline in the net realizable value of these assets as a
result of changing market conditions.

    PURCHASED TECHNOLOGY--Technology assets were recorded in connection with
Osicom's acquisition during the year ended January 31, 1997. The discounted
projected future cash flow from proven technology and software were capitalized
and amortized over their remaining estimated economic life (7 years) using the
straight-line method.

    We assess the recoverability of purchased technology primarily by
determining whether the amortization of the net book value of purchased
technology over its remaining life can be recovered through undiscounted future
operating cash flows of the acquired operation. The amount of the impairment, if
any, of the net book value of the excess cost over net assets acquired is
measured by determining the fair value of these assets primarily based on
projected discounted future operating cash flows from the purchased technologies
using a discount rate commensurate with our cost of capital. During the quarter
ended July 31, 1997, we recorded reductions to the net book value of purchased
technology of $3,750 to reflect the decline in the fair value of these assets as
the result of changing market conditions. This reduction has been included in
Other operating expenses.

    RESEARCH AND DEVELOPMENT--We expense research and development costs as
incurred in accordance with Statement of Financial Accounting Standards ("SFAS")
No. 2, "Accounting for Research and Development Costs". Research and development
costs are costs associated with products or processes for which technological
feasibility has not been proven and future benefits are uncertain. In-process
research and development purchased by us includes the value of products and
processes in the development stage and have not reached technological
feasibility; this amount is expensed at the date of purchase.

    REVENUE RECOGNITION--We generally recognize product revenue when the
products are shipped, all substantial contractual obligations, if any, have been
satisfied, and the collection of the resulting receivable is reasonably assured.
Revenue from installation is recognized as the services are performed to the
extent of the direct costs incurred. To date, installation revenue has not been
material. Revenue

B.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
from service obligations, if any, is deferred and recognized over the life of
the contract. Inventory or demonstration equipment shipped to potential
customers for field trials is not recorded as revenue. We accrue for warranty
costs, sales returns and other allowances at the time of shipment. Although our
products contain a software component, the software is not sold separately and
we are not contractually obligated to provide software upgrades to our
customers.

    WARRANTY AND CUSTOMER SUPPORT--We typically warrant our products against
defects in materials and workmanship for a period of one to five years from the
date of sale and a provision for estimated future warranty and customer support
costs is recorded when revenue is recognized. To date, warranty and customer
support costs have not been material.

    INCOME TAXES--Income taxes are accounted for in accordance with Statement of
Financial Accounting Standards No. 109 "Accounting for Income Taxes." The
statement employs an asset and liability approach for financial accounting and
reporting of deferred income taxes generally allowing for recognition of
deferred tax assets in the current period for future benefit of net operating
loss and research credit carryforwards as well as items for which expenses have
been recognized for financial statement purposes but will be deductible in
future periods. A valuation allowance is recognized, if on the weight of
available evidence it is more likely than not that some portion or all of the
deferred tax assets will not be realized. (See Note I).

    ADVERTISING--We expense advertising expenditures as incurred. Advertising
expenses consist of allowances given to customers as well as direct
expenditures. Advertising expenses for fiscal 2000, 1999 and 1998 were $11,
$536, and $290, respectively.

    INCOME AND LOSS PER COMMON SHARE--Statement of Financial Accounting
Standards ("SFAS") No. 128, "Earnings Per Share," requires dual presentation of
basic and diluted earnings per share ("EPS") on the face of the income
statement. It also requires a reconciliation of the numerator and denominator of
the basic EPS computation to the numerator and denominator of the diluted EPS
computation. (See Note M). Basic income and loss per common share is computed by
dividing net income or loss available to common shareholders by the weighted
average number of common shares outstanding during each period presented.
Diluted EPS is based on the weighted average number of common shares outstanding
as well as dilutive potential common shares, which in our case was none.
Potential common shares would not be included in the diluted loss per share
computation for fiscal 2000, 1999 and 1998 as they would be anti-dilutive.

    DERIVATIVE INSTRUMENTS--SFAS No. 133, "Accounting for Derivative Instruments
and Hedging Activities," is effective for financial statements with fiscal
quarters of all fiscal years beginning after June 15, 2000. The statement
establishes standards for accounting for derivatives and hedging instruments of
which we currently have none. We do not expect the adoption of SFAS No. 133 to
have a material effect, if any, on our financial position or results of
operations.

    COMPUTER SOFTWARE FOR INTERNAL USE--The Accounting Standards Executive
Committee issued Statement of Position ("SOP") 98-1, "Accounting for the Costs
of Computer Software Developed or Obtained for Internal Use," is effective for
financial statements with fiscal years beginning after

B.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
December 15, 1998. The SOP provides guidance on accounting for the costs of
computer software developed or obtained for internal use. The SOP requires that
we continue to capitalize certain costs of software developed for internal use
once certain criteria are met. The adoption of SOP 98-1 had no effect on our
financial position or results of operations.

    START-UP COSTS--Statement of Opinion 98-5, "Reporting on the Costs of
Start-up Activities," is effective for financial statements for fiscal years
beginning after December 31, 1998. The SOP provides guidance and examples of the
types of expenses associated with one-time (start-up) activities which under
this SOP must be expensed as incurred. The adoption of SOP 98-5 had no effect on
our financial position or results of operations.

C.  PROPERTY AND EQUIPMENT

as of January 31, 2000 and 1999:

H.  STOCKHOLDERS' EQUITY

    We are authorized to issue the following shares of stock:

       41,000 shares of Common Stock--Class A ($1.00 par value)

       9,000 shares of Common Stock--Class B ($1.00 par value)

    The Class B common stock is convertible on a one-for-one basis into Class A
common stock. The holders of Class A shares may elect eight directors separately
as a class while the holders of Class B shares may elect two directors
separately as a class. In any other matter voted upon by the shareholders, each
share of Class B has a 1/3 vote. The remaining rights, privileges of the two
classes of common stock are identical, including dividend and dissolution

    Our operations generate permanent and temporary differences for
depreciation, amortization, and valuation allowances. We have recorded a 100%
valuation allowance against our deferred tax assets, including net operating
loss and research credit carryforwards, in accordance with the provisions of
Statement of Financial Accounting Standards No. 109. Such allowance is
recognized if, based on the weight of available evidence, it is more likely than
not that some portion or all of the deferred tax assets will not be realized.

I.  INCOME TAXES (CONTINUED)
    At January 31, 2000, we have federal net operating losses which may be
available to reduce future taxable income. Among potential adjustments which may
reduce available loss carryforwards, the Internal Revenue Code of 1986, as
amended, (IRC), reduces the extent to which net operating loss carryforwards may
be utilized in the event there has been an "ownership change" of a company as
defined by applicable IRC provisions. We believe that the acquisition of 100% of
our outstanding stock in September, 1996 by Osicom resulted in such an ownership
change, and we intend to analyze the impact of this transfer on the continued
availability, for tax purposes, of our net operating losses incurred through
January 31, 2000. Further ownership changes in the future, as defined by the
IRC, may reduce the extent to which any net operating losses may be utilized.
These NOL carryforwards expire as follows:

K.  RELATED PARTY TRANSACTIONS

    From time to time we have received non-interest bearing advances from our
parent, including payment of various expense on our behalf and transfer of
assets from other subsidiaries of our parent which are used in our business. The
balance due our parent, included in non-current liabilities in the accompanying
financial statements, was $21,769 and $17,337 at January 31, 2000 and 1999,
respectively. The merger agreement entered into by our parent provides that the
balance due at closing will be contributed to our capital and we will have no
remaining debt outstanding due our parent.

    We manufacture assemblies for the Optical Networking business of our parent,
purchase components for as well as purchase assemblies from our parent's former
subsidiary located in Hong Kong, and purchased inventory from as well as
reimbursed engineering, occupancy and manufacturing support expenses to our
parent's former subsidiary, NETsilicon, Inc. The following data show the amounts
of these transactions with our affiliates.

L.  SUPPLEMENTAL CASH FLOW DISCLOSURES

    Interest expense and taxes paid approximated the related expenses for the
years ended January 31, 2000, 1999 and 1998.

    Assets transferred to us from our affiliates neither provided nor used cash.
Accordingly, assets with net book values of $2,147, $577 and $1,348 were
excluded from the statements of cash flows for fiscal 2000, 1999 and 1998,
respectively.

M.  CONCENTRATIONS OF CREDIT RISK

    Financial instruments that potentially subject us to concentrations of
credit risk consist primarily of temporary cash investments and trade
receivables. As regards the former, we place its temporary cash investments with
high credit financial institutions and limits, by policy, the amount of credit
exposure to any one institution. No accounts at a single bank accounted for more
than 10% of current assets.

    Concentrations of credit risk with respect to trade receivables are limited
because there is a large number of customers in our customer base spread across
many industries and geographic areas. Three customers each accounted for 19.4%,
18.7%, and 13.7% of fiscal 2000 net sales. One customer accounted for 16.3% of
fiscal 1999 net sales. One customer accounted for 16.1% of fiscal 1998 net
sales. At January 31, 2000 one customer accounted for 39.4% of net receivables.
At January 31, 1999 one customer accounted for 29.7% of net receivables.

N.  SUBSEQUENT EVENTS

    On April 11, 2000, Osicom entered into an agreement with Sync

<PAGE>
        (c)  CONVERSION OF OSICOM COMMON STOCK.  Other than shares to be
    canceled pursuant to Section 2.1(b), the outstanding shares of Osicom Common
    Stock shall be converted into the right to receive that number of validly
    issued, fully paid and nonassessable shares of Sync Common Stock that is
    equal to the number of shares of Sync Common Stock outstanding on the
    Closing Date (the "Merger Consideration"). The parties intend that
    immediately following the Merger, the Shareholder will own fifty percent
    (50%) of the outstanding Sync Common Stock. In addition, Sync, promptly
    after the Effective Time, shall issue options to purchase its Common Stock
    to Osicom employees in an amount equal to the number of shares of Sync
    Common Stock issuable pursuant to the stock options and convertible and
    exchangeable securities listed on Schedule 4.2(a) of the Disclosure
    Schedule, which Schedule shall be updated as of the Closing Date for
    purposes of this computation. Such options will not affect the Merger
    Consideration calculation.

    2.2  EXCHANGE PROCEDURES.  At the Closing, the Shareholder shall surrender
to Sync the share certificate(s) (the "Osicom Certificate") representing all of
the outstanding shares of Osicom Common Stock. The Osicom Certificate so
surrendered shall forthwith be canceled. As soon as reasonably practicable after
the Effective Time, the Shareholder shall, upon surrender to Sync of the Osicom
Certificate, together with such other documents as may be reasonably required by
Sync, be entitled to a share certificate(s) representing the number of shares of
Sync Common Stock into which the aggregate number of shares of Osicom Common
Stock shall have been converted pursuant to this Agreement. Each such share
certificate of Sync Common Stock issued to each holder will bear the following
legend on the face thereof:

       THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
       UNDER THE SECURITIES ACT OF 1933, AS AMENDED. NO TRANSFER, SALE,
       ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION OF THE SECURITIES

From and after the Effective Time, the Shareholder shall cease to have any
rights with respect to such shares of Osicom Common Stock formerly represented

                         OF THE SHAREHOLDER AND OSICOM

    The Shareholder and Osicom hereby represent and warrant to Sync as follows:

    3.1  CORPORATE ORGANIZATION.  Osicom, and each Subsidiary of Osicom, is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware. Osicom and each of its Subsidiaries has full corporate
power and authority to own their respective assets and to carry on their
respective businesses as now being conducted and are duly qualified or licensed
to do business as foreign corporations in good standing in the jurisdictions in
which the ownership of their respective property or the conduct of their
respective businesses requires such qualification or license, except
jurisdictions in which the failure to be so qualified or licensed would not,
individually or in the aggregate, have a Material Adverse Effect (as defined in
Section 10.16) on Osicom. Section 3.1 of the Disclosure Scheduleattached hereto
lists by name each of Osicom and the Subsidiaries of Osicom, each jurisdiction
in which each entity is qualified or authorized to do business and its
capitalization

each). Osicom has delivered to Sync complete and correct copies of the
certificate of incorporation and all amendments thereto, the by-laws as
presently in effect, and the minute books and stock transfer records of Osicom
and each of its Subsidiaries.

    3.2  CAPITALIZATION.

        (a) The authorized capital stock of Osicom consists of 50,000 shares of
    Class A Common Stock, par value $1.00 per share (the "Osicom Common Stock")
    of which 1,000 shares are issued and outstanding as of the date hereof and
    9,000 shares of Class B Common Stock, none of which are outstanding as of
    the date hereof. The Shareholder owns all of the shares of Osicom Common
    Stock issued and outstanding as of the date hereof. No other shares of any
    other class or series of capital stock of Osicom or securities exercisable
    or convertible into or exchangeable for capital stock of Osicom ("Osicom
    Capital Stock Equivalents") were authorized, issued or outstanding as of
    January 31, 2000. Since January 31, 2000, there have been no issuances of
    Osicom Common Stock or Osicom Capital Stock Equivalents. There are no
    subscriptions, options, warrants, calls, rights, contracts, commitments,
    understandings, restrictions or arrangements relating to the issuance, sale,
    transfer or voting of any shares, whether issued or unissued, of capital
    stock of Osicom or Osicom Capital Stock Equivalents, including any rights of
    issuance, conversion or exchange under any outstanding securities or other
    instruments, other than restrictions imposed by Federal and state securities
    laws. All of the shares of Osicom Common Stock are duly authorized, validly
    issued and outstanding and fully paid, nonassessable and free and clear of
    all pledges, mortgages, claims, options, rights of first refusal, liens,
    charges, encumbrances, security interests and limitations of voting rights
    of any kind or nature whatsoever ("Encumbrances"). Neither Osicom nor any of
    its Subsidiaries has any outstanding debt securities or other indebtedness
    or guarantees, except as specifically disclosed in the Osicom Financial
    Statements (as defined in Section 3.4).

        (b) Section 3.2(b) of the Disclosure Schedule contains a complete and
    correct list of all direct or indirect Subsidiaries of Osicom and the amount
    of capital stock or other equity interests owned by Osicom and its
    Subsidiaries in such Subsidiaries. All the outstanding shares of capital
    stock of each of the Subsidiaries of Osicom have been duly authorized,
    validly issued and are fully paid and non-assessable and, except as set
    forth in Section 3.2(b) of the Disclosure Schedule, are owned (of record and
    beneficially) by Osicom designed in Section 3.2(b) of the Disclosure
    Schedule, free and clear of all Encumbrances. Except for the Subsidiaries
    set forth in Section 3.2(b) of the Disclosure Schedule, neither Osicom nor
    any of its Subsidiaries owns or has any option or right to acquire, directly
    or indirectly, any capital stock or other equity securities of, or has any
    direct or indirect equity or ownership interest or debt investment in, any
    corporation, association, partnership, joint venture or other business.

    3.3  AUTHORIZATION, ETC.  Each of the Shareholder and Osicom has full power
and authority to execute and deliver this Agreement and to carry out the
transactions contemplated hereby. The execution and delivery of this Agreement
and the consummation of the transactions contemplated hereby have been duly
authorized by all necessary corporate action on the part of the Shareholder and
of Osicom and no other corporate proceedings on the part of Osicom, the
Shareholder or their respective stockholders are necessary to authorize this
Agreement or to consummate the transactions so contemplated (other than, with
respect to the Merger, the filing of the Certificate of Merger as required by
the DGCL). This Agreement has been duly and validly executed by Osicom and the
Shareholder and, assuming this Agreement constitutes the legal, valid and
binding agreement of the other parties hereto, constitutes a legal, valid and
binding agreement of Osicom and the Shareholder, enforceable against each of
them in accordance with its terms, except that (i) the enforcement hereof may be
limited by bankruptcy, insolvency, reorganization, moratorium or other similar
laws now or hereafter in effect relating to creditors' rights generally and

defenses and to the discretion of the court before which any proceeding therefor
may be brought.

Disclosure Schedule, neither Osicom nor any of its Subsidiaries has any
liabilities or obligations of any nature (whether known or unknown and whether
absolute, accrued, contingent or otherwise) except for liabilities or
obligations reflected on or reserved against the Osicom Balance Sheet or the
Osicom Interim Balance Sheet and current liabilities incurred in the ordinary
course of business and consistent with past practice since the respective dates
thereof.

    3.6  NO APPROVALS OR CONFLICTS.  Except as set forth in Section 3.6 of the
Disclosure Schedule, the execution, delivery and performance by Osicom and the
Shareholder of this Agreement and the consummation by Osicom and the Shareholder
of the transactions contemplated hereby will not (i) violate, conflict with or
result in a breach by Osicom of any provision of the certificate of
incorporation or by-laws of Osicom or any of its Subsidiaries, (ii) violate,
conflict with or result in a breach of any provision of, or constitute a default
by Osicom or any of its Subsidiaries (or an event which, with notice or lapse of
time or both, would constitute a default) or give rise to any right of

declaration, filing, application, qualification or registration with, any
governmental or regulatory authority, excluding from the foregoing clauses
(ii) and (iii) above, such violations, conflicts and breaches which,
individually or in the aggregate, would not have a Material Adverse Effect on
Osicom or prevent or delay the consummation of the transactions contemplated
hereby.

any of its Subsidiaries is in violation of any order, injunction, judgment,
ruling, law or regulation of any court or governmental authority applicable to
the property or business of Osicom or any such Subsidiary. Osicom and each of

authorizations reasonably necessary to conduct their respective businesses as
currently conducted and such licenses, permits and authorizations are valid and
in full force and effect.

Schedule, there are no claims, suits, actions, proceedings or investigations
(collectively, "Claims") pending or, to the best knowledge of Osicom or the
Shareholder, threatened against Osicom, any of its Subsidiaries, or the
transactions contemplated by this Agreement before any arbitrator, court or
governmental or regulatory authority or body, which, if decided unfavorably to

    or an unsolicited written expression of interest that can reasonably be
    expected to lead to a Takeover Proposal, shall be received by the Board of

    would, if consummated, result in a transaction more favorable to Sync's or
    the Shareholder's stockholders, as applicable, from a financial point of
    view than the transaction contemplated by this Agreement (any such more
    favorable Takeover Proposal being referred to in this Agreement as a
    "Superior Proposal"), and the Board of Directors of Sync or the Shareholder,
    as applicable, determines in good faith after consultation with outside
    legal counsel that it is necessary for such Board of Directors to evaluate
    the Superior Proposal in order to comply with its fiduciary duties to
    stockholders under applicable law, Sync or the Shareholder, as applicable,
    and its officers, directors, employees, investment bankers, financial
    advisors, attorneys, accountants and other representatives retained by it
    may furnish in connection therewith information and take such other actions

    unless Sync or the Shareholder, as applicable, shall have (i) terminated
    this Agreement pursuant to Section 8.1(e), and (ii) agreed to pay, without
    interest, to the Shareholder or Sync, as applicable, the sum of $1,000,000

        (c) by the Shareholder, if the Closing has not occurred on or before

    materially false, inaccurate or misleading representations and warranties of
    the Shareholder or Osicom contained herein or the breach or failure of the
    Shareholder or Osicom to comply in all material respects with the agreements
    and covenants contained herein to be performed by the Shareholder or Osicom

                                INDEMNIFICATION

    9.1  INDEMNIFICATION.

        (a)  INDEMNIFICATION BY THE SHAREHOLDER OF SYNC.  Subject to the limits
    set forth in this Section 9.1, the Shareholder agrees that from and after
    the date hereof the Shareholder shall, indemnify, defend and hold Sync, its
    Subsidiaries (including, without limitation, Osicom after the Effective
    Date) and their respective officers, directors, partners, stockholders,
    employees, agents and representatives (collectively, the "Sync Indemnified
    Persons") harmless from and in respect of any and all losses, damages, costs
    and reasonable expenses (including, without limitation, reasonable fees and
    expenses of counsel) (collectively, "Losses"), that such Sync Indemnified

                                      A-28
<PAGE>
    Persons or Sync or its Subsidiaries may incur arising out of or due to
    (i) any false, inaccurate, or misleading representation or warranty or the
    breach of any covenant by the Shareholder or Osicom in the Agreement,
    (ii) the termination of the Case Defined Benefit Plan; (iii) the early
    termination by Osicom of its real estate lease for property located in
    Aurora, Illinois; and (iv) the failure of Osicom to pay any owed Taxes and
    to file all required Tax Returns, and all fines and penalties associated
    therewith. The matters referred to in clause (i) of this paragraph (a) shall
    be subject to indemnification only as to claims made within the period
    ending twenty-four (24) months following the Effective Date (except as to
    matters referred to in Section 3.16, for which the time limit is the
    applicable statute of limitations).

        (b)  INDEMNIFICATION BY SYNC OF THE SHAREHOLDER.  Subject to the limits
    set forth in this Section 9.1, Sync agrees that from and after the date
    hereof Sync shall, for claims made within the period ending twenty-four
    (24) months following the Effective Date (except as to matters referred to
    in Section 4.16, for which the time limit is the applicable statute of
    limitations) indemnify, defend and hold the Shareholder and its officers,
    directors, partners, stockholders, employees, agents and representatives
    (collectively, the "Osicom Indemnified Persons" and, together with the Sync
    Indemnified Persons, the "Indemnified Persons") harmless from and in respect
    of any and all Losses that such Osicom Indemnified Persons may incur arising
    out of or due to any false, inaccurate, or misleading representation or
    warranty or the breach of any covenant by Sync in the Agreement. The matters
    referred to this paragraph (b) shall be subject to indemnification only as
    to claims made within the period ending twenty-four (24) months following
    the Effective Date (except as to matters referred to in Section 3.16, for
    which the time limit is the applicable statute of limitations).

        (c)  NOTICE AND OPPORTUNITY TO DEFEND.  If there occurs an event which a
    party asserts is an indemnifiable event pursuant to Section 9.1(a) or
    9.1(b), then Sync or the Shareholder as applicable, shall promptly notify
    the Shareholder or Sync, respectively (the "Indemnifying Party"). If such
    event involves any claim, or the commencement of any action or proceeding,
    by a third person against any of the Indemnified Persons, the Indemnified
    Person will give the Indemnifying Party prompt written notice of such claim
    or the commencement of such action or proceeding; provided, however, that
    the failure to provide prompt notice as provided herein will relieve the
    Indemnifying Party of its obligations hereunder only to the extent that such
    failure prejudices the Indemnifying Party hereunder. In case any such action
    shall be brought against any party seeking indemnification and the
    Indemnified Person shall notify the Indemnifying Party of the commencement
    thereof, the Indemnifying Party shall be entitled to participate therein or,
    following the delivery by the Indemnifying Party to the Indemnified Person
    of Indemnified Party's acknowledgment in writing that the relevant Loss is
    an indemnified liability hereunder and that the Indemnifying Party, in its
    good faith judgment, will be able to pay any award of money damages against
    the Indemnified Person in connection with such action, to assume the defense
    thereof, with legal counsel reasonably satisfactory to such Indemnified
    Person and, after notice from the Indemnified Person to such Indemnified
    Person of such election so to assume the defense thereof, the Indemnifying
    Party shall not be liable to the party or parties seeking indemnification
    hereunder for any legal expenses of other counsel or any other expenses
    subsequently incurred by such party or parties in connection with the
    defense thereof. The Indemnifying Party and the Indemnified Person agree to
    cooperate fully with each other and their respective legal counsel in
    connection with the defense, negotiation or settlement of any such action or
    asserted liability. The Indemnified Person shall have the right to
    participate at his own expense in the defense of such action or asserted
    liability. If the Indemnifying Party assumes the defense of an action
    (a) no settlement or compromise thereof may be effected (i) by the
    Indemnifying Party without the written consent of the Indemnified Person
    (which consent shall not be unreasonably withheld or delayed) unless
    (x) there is no finding or admission of any violation of law or any
    violation of the rights of any person by any Indemnified Person and no
    adverse effect on any other claims that may be made

                                      A-29
<PAGE>
    against any Indemnified Person and (y) all relief provided is paid or
    satisfied in full by the Indemnifying Party or (ii) by the Indemnified
    Person without the written consent of Indemnifying Party (which consent
    shall not be unreasonably withheld or delayed) and (b) the Indemnified
    Person may subsequently assume the defense of such action if a court of
    competent jurisdiction determines that the Indemnifying Party is not
    vigorously defending such action and the Indemnifying Party shall bear all
    costs and expenses incurred by the Indemnified Party in its defense of such
    action, including without limitation, fees and expenses of legal counsel. In
    no event shall the Indemnifying Party be liable for any settlement effected
    without its written consent

        (d)  PAYMENT.  On each occasion that any Indemnified Person shall be
    entitled to indemnification or reimbursement under this Section 9.1, the
    Indemnifying Party shall, at each such time, promptly pay by wire transfer,
    to the Indemnified Person the aggregate amount of such Loss. To the extent
    the Indemnified Person is the Shareholder and/or Osicom and Sync makes a
    payment to a third party or incurs defense costs subsequent to the Effective
    Date with respect to a matter subject to indemnification hereunder, then the
    Loss payable to the Shareholder shall equal the amount of such payment and
    costs, which the Surviving Corporation shall pay to the Shareholder. To the
    extent that the Indemnified Person is a Sync Indemnified Person, and Sync
    makes a payment to a third party or incurs defense costs subsequent to the
    Effective Date with respect to a matter subject to indemnification hereunder
    by the Shareholder, then the Loss payable to Sync shall equal the amount of
    such payment and costs, which the Shareholder shall pay to Sync. If any
    Indemnified Person shall be entitled to indemnification under this
    Section 9.1, the Indemnifying Party shall reimburse in cash the Indemnified
    Person's actual out-of-pocket expenses, if any, arising as a result of
    defending against any such claim, action or proceeding.

        (e)  MINIMUM LIABILITY.  Neither party shall have any liability to the
    other under this Article IX unless such party's aggregate Losses exceed
    $250,000, in which event the Indemnifying Party shall be liable only for all
    such Losses above that amount. Neither party shall have any liability under
    this Article IX in an amount greater that Sync's market capitalization as of
    the date of this Agreement..

                                   ARTICLE X
                                 MISCELLANEOUS

                      OPINION OF FINANCIAL ADVISOR TO SYNC

                        [letterhead of Alliant Partners]

April 10, 2000

Board of Directors
Sync Research, Inc.
12 Morgan
Irvine, CA 92618

Gentlemen:

    You have requested our opinion as to the fairness, from a financial point of
view, to the shareholders of Sync Research, Inc. ("Sync" or the "Company") in
connection with the transactions contemplated by the Agreement and Plan of
Merger (the "Agreement") dated April 10, 2000 by and among

    1.  Sync Research, Inc. ("Sync"), a Delaware corporation

    2.  Osicom Technologies, Inc. ("Parent"), a New Jersey corporation

    3.  Osicom Technologies, Inc., doing business as Entrada Networks ("Entrada"
       or "Entrada"), a Delaware Corporation in which reside substantially all
       of the assets of the Network Access division of Osicom Technologies Inc.
       New Jersey

    4.  a wholly-owned subsidiary of Sync Research, Inc. (yet to be created),
       formed for the purpose of this transaction

and the issuance of common stock, par value $0.001, of Sync (the "Shares")
pursuant thereto. The total consideration to be paid to Parent for Entrada is
equal to the number of shares of Sync Common Stock outstanding at the time of
closing, to be issued at closing. As of April 10, 2000, that number was
3,531,007. The transactions described above are collectively referred to herein
as the "Transaction".

    Alliant Partners, as part of its investment banking business, is regularly
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions and corporate partnering transactions. We have acted as
financial advisor to Sync in connection with the Transaction and will receive a
fee for our services, including rendering this opinion, a significant portion of
which is contingent upon the consummation of the Transaction.

    In arriving at our opinion, we have reviewed the Agreement and all of the
Exhibits and schedules, and have reviewed financial, product and other
information that was furnished to us by Sync and Parent. We also have held
discussions with members of the senior management of Sync and Parent regarding
the historic and current business operations and future risks and prospects of
the Company, including their expectation for certain strategic benefits of the
transaction. As part of these discussions, we also reviewed other transactions
contemplated by the Company over the last twelve months. In addition, we have
compared certain financial and securities data, both historic and projected, of
Entrada with those of various other companies engaged in businesses we
considered comparable with

                                      B-1
<PAGE>
securities which are traded in public markets, analyzed prices paid in certain
other similar business combinations, and conducted such other financial studies,
analyses and investigations as we deemed appropriate for purposes of this
opinion.

    We have assumed, without independent verification, the accuracy,
completeness and fairness of all of the financial statements, product
information, marketing strategies and other information regarding Entrada that
has been provided to us by Parent and its representatives. We did not make any
independent evaluation of Entrada's assets or intellectual property, nor did we
review any of Parent's corporate records.

    Based on the foregoing and such other factors as we deem relevant, we are of
the opinion, as of the date hereof, that the consideration to be paid by Sync in
connection with the Transaction is fair, from a financial point of view, to Sync
and its shareholders.

Sincerely Yours,

/s/ ALLIANT PARTNERS

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20.  INDEMNIFICATION OF OFFICERS AND DIRECTORS

    Section 145(a) of the General Corporation Law of the State of Delaware
("Delaware Corporation Law") provides, in general, that a corporation shall have
the power to indemnify any person who was or is a party or is threatened to be
made a party to any threatened, pending or completed action, suit or proceeding,
whether civil, criminal, administrative or investigative (other than an action
by or in the right of the corporation), because the person is or was a director
or officer of the corporation. Such indemnity may be against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by the person in connection with such action, suit or
proceeding, if the person acted in good faith and in a manner the person
reasonably believed to be in or not opposed to the best interests of the
corporation and if, with respect to any criminal action or proceeding, the
person did not have reasonable cause to believe the person's conduct was
unlawful.

    Section 145(b) of the Delaware Corporation Law provides, in general, that a
corporation shall have the power to indemnify any person who was or is a party
or is threatened to be made a party to any threatened, pending or completed
action or suit by or in the right of the corporation to procure a judgment in
its favor because the person is or was a director or officer of the corporation,
against any expenses (including attorneys' fees) actually and reasonably
incurred by the person in connection with the defense or settlement of such
action or suit if the person acted in good faith and in a manner the person
reasonably believed to be in or not opposed to the best interests of the
corporation.

    Section 145(g) of the Delaware Corporation Law provides, in general, that a
corporation shall have the power to purchase and maintain insurance on behalf of
any person who is or was a director or officer of the corporation against any
liability asserted against the person in any such capacity, or arising out of
the person's status as such, whether or not the corporation would have the power
to indemnify the person against such liability under the provisions of the law.

    Article X of the Registrant's Certificate of Incorporation (incorporated by
reference herein) provides for indemnification of directors, officers and other
persons as follows:

        "A. To the fullest extent permitted by the Delaware General Corporation
    Law as the same exists or as may hereafter be amended, a director of the
    Corporation shall not be personally liable to the Corporation or its
    stockholders for monetary damages for breach of fiduciary duty as a
    director.

        B. The Corporation shall indemnify to fullest extent permitted by law
    any person made or threatened to be made a party to an action or proceeding,
    whether criminal, civil, administrative or investigative, by reason of the
    fact that he, his testator or intestate is or was a director, officer or
    employee of the Corporation or any predecessor of the Corporation, or serves
    or served at any other enterprise as a director, officer or employee at the
    request of the Corporation or any predecessor to the Corporation.

        C. Neither any amendment nor repeal of this Article X, nor the adoption
    of any provision of this Certificate of Incorporation inconsistent with this
    Article X, shall eliminate or reduce the effect of this Article X in respect
    of any matter occurring, or any cause of action, suit or claim that, but for
    this Article X, would accrue or arise, prior to such amendment, repeal or
    adoption of an inconsistent provision."

                                      II-1
<PAGE>
    Article VI of the Registrant's Bylaws (incorporated by reference herein)
provides in pertinent part that:

        "INDEMNIFICATION OF DIRECTORS AND OFFICERS.  The corporation shall, to
    the maximum extent and in the manner permitted by the General Corporation
    Law of Delaware, indemnify each of its directors and officers against
    expenses (including attorneys' fees), judgments, fines, settlements and
    other amounts actually and reasonably incurred in connection with any
    proceeding, arising by reason of the fact that such person is or was an
    agent of the corporation. For purposes of this Section 6.1, a "director" or
    "officer" of the corporation includes any person (i) who is or was a
    director or officer of the corporation, (ii) who is or was serving at the
    request of the corporation as a director or officer of another corporation,
    partnership, joint venture, trust or other enterprise, or (iii) who was a
    director or officer of a corporation which was a predecessor corporation of
    the corporation or of another enterprise at the request of such predecessor
    corporation.

        INDEMNIFICATION OF OTHERS.  The corporation shall have the power, to the
    maximum extent and in the manner permitted by the General Corporation Law of
    Delaware, to indemnify each of its employees and agents (other than
    directors and officers) against expenses (including attorneys' fees),
    judgments, fines, settlements and other amounts actually and reasonably
    incurred in connection with any proceeding, arising by reason of the fact
    that such person is or was an agent of the corporation. For purposes of this
    Section 6.2, an "employee" or "agent" of the corporation (other than a
    director or officer) includes any person (i) who is or was an employee or
    agent of the corporation, (ii) who is or was serving at the request of the
    corporation as an employee or agent of another corporation, partnership,
    joint venture, trust or other enterprise, or (iii) who was an employee or
    agent of a corporation which was a predecessor corporation of the
    corporation or of another enterprise at the request of such predecessor
    corporation.

        INSURANCE.  The corporation may purchase and maintain insurance on
    behalf of any person who is or was a director, officer, employee or agent of
    the corporation, or is or was serving at the request of the corporation as a
    director, officer, employee or agent of another corporation, partnership,
    joint venture, trust or other enterprise against any liability asserted
    against him or her and incurred by him or her in any such capacity, or
    arising out of his or her status as such, whether or not the corporation
    would have the power to indemnify him or her against such liability under
    the provisions of the General Corporation Law of Delaware."

    The Registrant has entered into indemnification agreements with its
directors containing provisions which are in some respects broader than the
specific indemnification provisions contained in the Delaware General
Corporation Law. The indemnification agreements may require the Registrant,
among other things, to indemnify its directors against certain liabilities that
may arise by reason of their status or service as directors (other than
liabilities arising from willful misconduct of a culpable nature), to advance
their expenses incurred as a result of any proceeding against them as to which
they could be indemnified, and to obtain director's insurance if available on
reasonable terms.

    The Registrant has also obtained directors and officers' liability insurance
covering, subject to certain exceptions, actions taken by the Registrant's
directors and officers in their capacities as such.

ITEM 22.  UNDERTAKINGS

    The undersigned Registrant hereby undertakes:

        (1)  that, for purposes of determining any liability under the
    Securities Act of 1933, each filing of the registrant's annual report
    pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of
    1934 (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 this 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;

        (2)  that prior to any public reoffering of the securities registered
    hereunder through use of a prospectus which is a part of this registration
    statement, by any person or party who is deemed to be an underwriter within
    the meaning of Rule 145(c), the issuer undertakes that such reoffering
    prospectus will contain the information called for by the applicable
    registration form with respect to reofferings by persons who may be deemed
    underwriters, in addition to the information called for by the other items
    of the applicable form;

        (3)  that every prospectus (i) that is filed pursuant to paragraph (2)
    immediately preceding, or (ii) that purports to meet the requirements of
    Section 10(a)(3) of the Act and is used in connection with an offering of
    securities subject to Rule 415, will be filed as a part of an amendment to
    the registration statement and will not be used until such amendment is
    effective, and that, for purposes 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;

        (4)  to respond to requests for information that is incorporated by
    reference into the prospectus pursuant to Items 4, 10(b), 11, or 13 of this
    Form, within one business day of receipt of any such request, and to send
    the incorporated documents by first class mail or other equally prompt
    means, including information contained in documents filed after the
    effective date of this registration statement through the date of responding
    to such request; and

        (5)  to supply by means of a post-effective amendment all information
    concerning a transaction, and the company being acquired involved therein,
    that was not the subject of and included in this registration statement when
    it became effective.

    Insofar as indemnification for liabilities under the Securities Act of 1933
may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 20 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. If a claim of
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 a 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.

Sync Research, Inc.
12 Morgan
Irvine, CA  92618

         REGISTRATION STATEMENT ON FORM S-4 (FILE NO. 333-________)

Ladies and Gentlemen:

         We have examined the Registration Statement on Form S-4 (No.
333-______) filed by you with the Securities and Exchange Commission (the
"Commission") on _________, 2000 (the "Registration Statement"), in connection
with the registration under the Securities Act of 1933, as amended, of 4,300,000
shares of your Common Stock (the "Shares"). As your counsel in connection with
this transaction, we have examined the proceedings taken and are familiar with
the proceedings proposed to be taken by you in connection with the issuance of
the Shares.

         We have also examined instruments, documents, and records which we
deemed relevant and necessary for the basis of our opinion hereinafter
expressed. In such examination, we have assumed the following: (a) the
authenticity of original documents and the genuineness of all signatures; (b)
the conformity to the originals of all documents submitted to us as copies; and
(c) the truth, accuracy, and completeness of the information, representations,
and warranties contained in the records, documents, and certificates we have
reviewed.

         Based on such examination, it is our opinion that the Shares when
issued in the manner described in the Registration Statement and the Agreement
and Plan of Merger dated as of April 10, 2000 by and between you, Sync Research
Acquisition Corp., Osicom Technologies, Inc., a New Jersey corporation, and
Osicom Technologies, Inc., a Delaware corporation, will be legally and validly
issued, fully paid and non-assessable.

         We are admitted to practice law only in the State of California, and we
express no opinion concerning any laws other than the laws of the State of
California and the federal laws of the United States.

         We hereby consent to the use of this opinion as an exhibit to said
Registration Statement, and further consent to the use of our name wherever
appearing in said Registration Statement, including the Prospectus constituting
a part thereof, and in any amendment thereto.


<PAGE>

In giving such consent, we do not consider that we are "experts" within the
meaning of such term as used in the Securities Act of 1933, as amended, or the
rules and regulations of the Securities and Exchange Commission issued
thereunder, with respect to any part of the Registration Statement, including
this opinion as an exhibit or otherwise.

                                      Very truly yours,

6.    TAXES:

      A. Landlord shall pay, prior to delinquency, all real estate taxes,
assessments and charges which are levied, imposed, or assessed upon or against
the leased premises. If Landlord shall fail to pay any
<PAGE>

such taxes, assessments, or charges prior to delinquency, Tenant shall have the
right to pay same and to deduct from any rent which may then or thereafter be
due all amounts expended by Tenant in making such payment. Should aforesaid
taxes exceed in any lease year the amount paid during the Base Year, Tenant
shall pay its proportionate share of such increase. Such proportionate share
shall consist of the relation its space on a leasable square footage basis bears
to the total leasable square footage of the building of which the leased
Premises are a part. The leasable square footage of the Premises comprises

Commission) and the term "Base Year" shall mean the twelve (12) month period
beginning July 1, 1990 and ending June 30, 1991; provided, that the Base Year
shall be the year in which real estate taxes and assessments are based on the
Improvements as improved by the Tenant Improvements and the year in which
premiums for fire and extended coverage insurance reflect the Tenant's occupancy
of the Premises. Landlord shall give Tenant prompt notice of any proposed
increase in real estate taxes and assessments and Tenant shall be entitled, at
its own expense, and through its own counsel, to participate with Landlord or
independently to contest or oppose any such increase. Landlord shall cooperate
with Tenant as may be reasonably required in any such contest. All refunds of
real estate taxes and assessments attributable to the Lease Term and which have
been paid by Tenant shall belong to Tenant.

occurs from the occupancy and use of the Premises at the commencement of this
Lease Agreement and which causes any increase in premiums for fire, and extended
coverage insurance or rental insurance on the Improvements of which the Premises
are a part above the then current rate, the Tenant shall pay the additional
premiums by reason thereof . Bills for such additional premiums shall be
rendered by Landlord to Tenant at such times as Landlord may elect and shall be
due from and payable by Tenant when rendered, and the amount thereof shall be
deemed to be, and be paid as additional rent.

      F. Tenant shall not be obligated to pay Tenant's Share of such insurance
premiums if such increase is caused by the acts, omissions to act, or negligence
of the Landlord or any other tenant of the Improvements or any person, firm or
corporation employed at the Landlord's or such tenant's request.

8.    COMMON AREA MAINTENANCE CHARGES:

      Tenant covenants to pay Landlord, as additional rent, Tenant's Share of

immediately prior to the casualty, but not later than sixty (60) days after the
casualty. If said restorations are not accomplished within said sixty (60) days,

"Governmental Regulations"), whether now in effect or hereafter promulgated,
applicable to Tenant's use and occupancy of the Premises; provided, however,
that (i) Landlord represents that the Tenant's use and occupancy of the
Premises, and the Improvements and Tenant Improvements, comply or will comply,
as of the Commencement Date and thereafter, with all Governmental Regulations
and (ii) Tenant shall have the right to contest the applicability and/or
validity of any of the above so long as by reason of such action, the Premises
or the Improvements would not be in danger of forfeiture or loss.

17.   CONDEMNATION:

Premises shall be taken by eminent domain, then at the option of the Tenant or
the Landlord the Lease shall terminate as of, and the rent shall be apportioned
to and abate from and after, the date of taking, commensurate with the area so
taken and to the extent that the Tenant is prevented from carrying on its
business in the Premises and Tenant shall have no right to participate in any
award or damages for such taking (except as set forth in sub-paragraph D hereof)
and hereby assigns all of its right, title and interest therein to Landlord. For
purposes of this paragraph 17, "a substantial part of the Premises" shall mean a
taking of all or any portion of the Premises which renders Tenant substantially
unable to carry on its business on the Premises or
<PAGE>

use the parking spaces which are part of the Premises in accordance with
Paragraph 1.

      B. If during the term of this Lease, less than a substantial part of the
Premises (as hereinbefore defined) shall be taken by eminent domain, this Lease
shall remain in full force and effect according to its terms; and Tenant shall
have no right to participate in any award or damages for such taking (except as
set forth in sub-paragraph D. hereof) and hereby assigns all of its right, title
and interest therein to Landlord, provided that Landlord shall at its expense
promptly make such repairs and improvements as shall be necessary to restore the
Premises to substantially the same efficiency as before the taking, but not
later than ninety (90) days after such taking in which case the Tenant may
terminate this Lease by written notice to the Landlord, which termination shall
take effect upon the giving of such notice.

      C. For the purpose of this paragraph 17, "taken by eminent domain" or
"taking under the power of eminent domain" shall include a negotiated sale or
lease and transfer of possession to a condemning authority under bona fide
threat of condemnation for public use, and Landlord alone shall have the right
to negotiate with the condemning authority and conduct and settle all litigation
connected with the condemnation. As hereinabove used, the words "award of
damage" shall, in the event of such sale or settlement, include the purchase or
settlement price of any such negotiated transfer.

      D. Nothing herein shall be deemed to prevent Tenant from claiming,
negotiating, and receiving from the condemning authority, if legally payable,
compensation for the taking of Tenant's own tangible property, improvements upon
the leased Premises constructed at Tenant's sole expense, and damages for
Tenant's loss of business, business interruption and/or removal and relocation.
Should any condemnation be effected without a cancellation of the Lease, there
shall be an appropriate reduction in rental.

      E. The Landlord shall promptly notify the Tenant upon learning of any
eminent domain proceedings affecting the Premises. In any such proceedings, the
Landlord shall use its best efforts to ensure that the
<PAGE>

Tenant shall have at least six (6) months after a taking of all or a substantial
part of the Premises to relocate to an alternative space.

18.   LANDLORD'S RIGHT TO PERFORM TENANT'S COVENANTS:

      After the occurrence of an Event of Default, Landlord shall, after
reasonable notice to Tenant (except in case of emergencies) have the right (but
not the duty) to enter the Premises, if necessary, to perform any covenant or
duty required of the Tenant by this Lease or by law, but the reasonable cost
thereof shall be deemed to be additional rent, and shall give the Landlord the
same rights and remedies as though the additional rent were part of the monthly
rent due the Landlord under this Lease.

19.   INDEMNIFICATION OF LANDLORD:

      Except with respect to claims arising from Landlord's act, omissions to
act, or negligence or that of its agents, servants or employees, including,
without limitation, Landlord's failure to make repairs required of it to be made
pursuant to this Lease or Landlord's construction of the Tenant Improvements,
Tenant covenants to indemnify and save Landlord harmless (to the extent not
reimbursed by insurance required by this Lease to be furnished by Tenant) from
any and all claims for liability of any nature whatever arising from any use,
occupancy, construction, repairs, or other work or activity done in, on or about
the Premises during the term or from any condition of the Premises or anything
thereon or therein during the term, or from any occurrence whatever in, on or
about the Premises during the term, including all Landlord's reasonable costs,
expenses and counsel fees in connection with any such claim.

20.   DEFAULT PROVISIONS:

      Upon the occurrence of an Event of Default, Landlord may elect to
immediately terminate this Lease by serving a written notice upon Tenant.

      Each of the following events shall be deemed an Event of Default by Tenant
within the meaning of this Lease:

            (1) the failure to pay any installment of Basic Rental or additional
rent when due and payable if such failure continues for ten (10) days after
written notice from the Landlord that the same are due;

            (2) the failure to perform any of the other covenants or conditions
of this Lease on the part of Tenant to be performed within thirty (30) days
after notice from the Landlord of such failure to perform provided that if such
failure to perform is not susceptible to cure within such thirty (30) days then
so long as the Tenant commences such cure within thirty (30) days and diligently
pursues such cure, such failure to perform shall not be an Event of Default;

            (3) the making of an assignment by Tenant for the benefit of its
creditors;

            (4) the appointment of a receiver or trustee of all or part of

First Right of Refusal on any space that becomes available space in the
building, subject to existing leases at then market rental rate. Tenant shall

(3) Brokers shall then have Fourteen (14) calendar days to submit simultaneously

      The renewal rate quoted by the Brokers shall be quoted on an Industrial
Gross Basis and the rate shall be flat, i.e. non-escalating during the five (5)
year renewal period. The three (3) Broker rate quotes shall be averaged and then
multiplied by 9.5% to establish a binding rental rate for the renewal period.
Example:

      Broker #1   Quote       -     $5.00

      Broker #2   Quote       -     $6.00

      Broker #3   Quote       -     $5.50

      Calculation:

      ($5.00 + $6.00 + $5.50) (3 x .95)   $5.23

      Example Renewal Rate:

      $5.23 Industrial Gross Flat for five (5) years

      IN WITNESS WHEREOF, the parties hereto have executed this Second Amendment
of Lease the day and year first written above.

                       AMENDMENT NO. 2 TO LEASE AGREEMENT

      THIS AMENDMENT NO. 2 TO LEASE AGREEMENT is made this 22 day of April,
1999, by and between CHIPPEWA LIMITED PARTNERSHIP, a Maryland limited
partnership, hereinafter called "Landlord," and OSICOM TECHNOLOGIES, INC., a
Delaware corporation f/k/a CASE/DATAEL, INC.), hereinafter called "Tenant."

      WHEREAS Landlord and Tenant are parties to a Lease Agreement dated October
4, 1989, as modified by First Amendment of Lease dated October 19, 1994 (the
"Lease"); and

      WHEREAS Tenant has requested Landlord to make certain modifications to the

herein contained, the Lease is hereby amended as follows:

      1. Effective June 1, 1999 Tenant shall vacate [make best efforts to

<PAGE>

      3. Landlord shall install the tenant improvements set forth in the Tenant
Improvement Specifications attached hereto as Exhibit A-1 and the Floor Plan
attached hereto as Exhibit A-2. Landlord, based upon its discussions with
Tenant, has estimated that the total costs of the tenant improvements (such
costs to include all amounts paid to contractors, subcontractors, material
suppliers, design or other professionals, permit fees, and etc.) is One Hundred
Eighty-five Thousand Dollars ($185,000.00) (the "Tenant Improvement Allowance").
Any increase in the amount of such total costs, over the Tenant Improvement
Allowance, including, but not limited to, increases resulting from additions to
or modifications of the attached exhibits, shall be Tenant's obligation and
shall be paid for by Tenant within ten (10) days after demand. Landlord
Estimates that the tenant improvements will be substantially completed within
sixty (60) days after the later of (i) the date of this Amendment, or (ii) the
date of full execution of the lease with Earthshell Corporation, as described in
paragraph 10 below. Notwithstanding the foregoing, Landlord shall have no
liability to Tenant if the tenant improvements are not completed by such date
and, in such event, Tenant shall be required to perform in accordance with the
terms of the Lease and this Amendment, and Landlord shall continue to utilize
commercially reasonable efforts to complete the tenant improvements as promptly
as reasonably possible. Tenant shall cooperate with Landlord in Landlord's
efforts to construct the tenant improvements and shall [make reasonable efforts
to] remove all of its goods and materials from the portions of the Premises upon
which Landlord's contractors are working, so as to provide a safe and clear
working environment for Landlord's contractors. Landlord agrees that it will
provide a copy of all costs associated with the tenant improvements to Tenant
within twenty (20) days after full execution of this Amendment. Landlord agrees
that the carpet it will install, as a part of the tenant improvements, will be a
commercial grade carpet that under normal wear and tear with proper maintenance
will have a useful life of not less than five and one-half (5%) years.

      4. Until May 30, 1999 Tenant shall continue to pay Basic Rental in
accordance with the terms of the Lease. Beginning June 1, 1999 (if Tenant
complies with paragraph 1 above), the Basic Rental payable with respect to
the Lease and the Premises shall be changed and, beginning on such date,
Tenant will pay to Landlord at % Emory Hill Management Co., Inc., Suite 100,
92 Read's Way, New Castle, Delaware 19720, or at such other place as Landlord
shall from time to time direct, the Basic Rental in the amounts set forth
below. The Basic Rental shall be payable in equal monthly installments, in

                                        2
<PAGE>

advance and without demand, on the first day of each and every month during the
term of the Lease, commencing on June 1, 1999. Basic Rental shall be as follows:

      Term                    Annual Basic Rental     Monthly Basic Rental

June 1, 1999 to
April 30, 2000                      $371,970.80             $30,997.57

May 1, 2000 to
April 30, 2001                      $379,410.21             $31,617.52

May 1, 2001 to
April 30, 2002                      $386,998.41             $32,249.87

May 1, 2002 to
April 30, 2003                      $394,738.38             $32,894.86

May 1, 2003 to
April 30, 2004                      $402,633.14             $33,552.76

May 1, 2004 to
October 31, 2004                    $410,685.80             $34,223.87

            Notwithstanding anything to the contrary contained in this paragraph
4, the foregoing rent schedule is based upon the assumption that the actual
total costs of the tenant improvements (the "Actual Costs") are at least one
Hundred Eighty-five Thousand Dollars ($185,000.00). In the event that the Actual
Costs is less than the Tenant Improvement Allowance, then the amount of Basic
Rental shall be recalculated and shall be reduced by an amount equal to that
obtained by amortizing the difference between the Tenant Improvement Allowance
and the Actual Costs on a monthly basis over a ten (10) year period at an
interest rate of ten percent (10%). For instance, if the Actual Costs are One
Hundred Thirty-five Thousand Dollars ($135,000.00), then the amount of Basic
Rental payable for the period May 1, 1999 to April 30, 2000 would be Three
Hundred Sixty-four Thousand Forty-one and 68/100 Dollars ($364,041.68) and the
monthly Basic Rental payment for such period would be Thirty Thousand Three
Hundred Thirty-six and 81/100 Dollars ($30,336.81), and such amount would be
increased at the rate of two percent (2%) per year for each of the remaining
lease years during the term.

      5. The current base year for all purposes of the Lease, including, but not
limited to, taxes(in accordance with paragraph 6 of the Lease), fire and
extended coverage and rental insurance (in accordance with paragraph 7 of the
Lease), and common area maintenance charges (in accordance with paragraph 8 of
the Lease) will not change and will remain the same as it was when the Lease was


                                        3
<PAGE>

originally executed on October 4, 1989. Tenant's proportionate share, however,
shall (if Tenant is in compliance with paragraph 1 above) change effective June
1, 1999 and shall be reduced from seventy-four and fifty-eight one hundredths
percent (74.58%) to thirty-eight and fifty-four one hundredths percent (38.54%).

      6. Paragraph 4 of the Lease is deleted in its entirety and is replaced
with the following:

            Late Payment:

            In the event that any payment required by Tenant under the
            provisions of this Lease shall not be paid when due, Tenant shall,
            upon demand, pay to Landlord (i) a late charge equal to the maximum
            late charge contained in or mandated by the loan documents
            evidencing or securing any first lien affecting the improvements
            from time to time, and (ii)interest on such payment from the date
            when due until paid at the rate of eighteen percent (18%) per annum.
            The late charges imposed under this paragraph shall be deemed "rent"
            for all purposes under this Lease, are not penalties and have been
            agreed to by Landlord and Tenant as necessary to compensate Landlord
            for its additional costs associated with late payment.

      7. Landlord is currently in possession of a security deposit under the
Lease in the amount of Forty-eight Thousand Two Hundred Twenty-eight Dollars
($48,228. 00). Effective June 1, 1999, Landlord, provided Tenant is not in
default, will credit Seventeen Thousand Two Hundred Thirty and 43/100 Dollars
($17,230.43) against the Basic Rental payment due on June 1, 1999. The balance
of the amount now being held by Landlord, Thirty Thousand Nine Hundred
Ninety-seven and 57/100 Dollars ($30,997.57), shall continue to be held by
Landlord as a security deposit, which sum shall be held without payment of
interest as security for the performance by Tenant of its obligations under the
Lease. Landlord is authorized to deposit those funds in a non-interest bearing
account commingled with Landlord's general funds or otherwise, and Landlord
shall not be responsible for the solvency of the depository so long as it is


                                        4
<PAGE>

insured by the Federal Deposit Insurance Corporation or similar insurer. If
Tenant shall perform all such obligations, said security deposit shall be
refunded to Tenant, without interest, within thirty (30) days after termination
of the Lease. If Tenant shall default in any obligation, Landlord shall be
entitled to apply any or all of said security deposit toward Landlord's damages
as determined by Landlord, and Tenant shall, within five (5) days after notice
thereof, deposit with Landlord an amount sufficient to restore said security
deposit to its original amount, which amount shall constitute "rent" under this
Lease.

      8. Paragraphs 6, 8 and 10 of the October 19, 1994 First Amendment to
Lease, the Rider #2 to Lease Agreement Option to Renew and the Rider #3 to Lease
Agreement Rights of Expansion and any other rights of renewal, expansion,
termination, first refusal or similar rights contained in the Lease are all
hereby deleted from the Lease and declared to be null and void and of no force
or effect. The following renewal right shall be the only right of renewal of
Tenant under or in connection with the Lease:

            Tenant shall have the Option to Renew the Lease for one (1)
additional five (5) year term upon giving written notice of intention to renew
to Landlord not less than one hundred eighty (180) days prior to the expiration
of the term of the Lease, as described in paragraph 2 above. Any such written
notice must advise Landlord of Landlord's obligation, described below in this
paragraph 8, to make an initial determination of the "Market Rate" for the
renewal term. All terms and conditions of the Lease shall remain in full force
and effect during the renewal term, except that there shall be no further right
of renewal and the Basic Rental for the renewal term shall be the "Market Rate,"
as defined below, effective the first day of the renewal term.

            The Option to Renew granted to Tenant is personal to Tenant and may
not be exercised or be assigned, voluntarily or otherwise, by or to any person
or entity other than Tenant without the prior written consent of Landlord.
Additionally, at Landlord's option, the Option to Renew shall be null and void
if, either at the time Tenant exercises such option or at the time such renewal
term is to commence, Tenant is in default under any provision of the Lease.

            The following procedure shall be used to determine the Market Rate,
for the renewal term. Not less than one hundred fifty (150) days prior to the
commencement of the renewal term, Landlord shall send to Tenant a written notice


                                        5
<PAGE>

specifying its determination of the Market Rate. Within twenty (20) days after
receipt of such notice from Landlord, Tenant shall send Landlord a written
notice of Tenant's acceptance or challenge of Landlord's determination of such
Market Rate, provided, however, that in the event that Tenant fails to respond
within such twenty (20) day period, Tenant shall be deemed to have accepted
Landlord's determination of the Market Rate.

            In the event that Tenant challenges Landlord' s determination of the
Market Rate and Landlord and Tenant are not able to agree on such Market Rate
within fifteen (15) days (hereinafter referred to as the "Negotiation Period")
after Landlord receives Tenant's initial rejection of Landlord's determination
of such Market Rate, then Landlord and Tenant shall each, within ten (10) days
after the expiration of the Negotiation Period, select an appraiser, each of
whom shall be an MAI-certified real estate appraiser with at least five (5)
years, experience in the Columbia, Maryland market who shall determine the
Market Rate in accordance with this paragraph. The appraisers shall be
instructed to complete the appraisal procedure independently and to submit their
written determinations to Landlord and Tenant within thirty (30) days after
their appointment.

            In the event that the higher determination of the Market Rate
submitted by one of the appraisers is equal to or less than one hundred fifteen
percent (115%) of the determination of the Market Rate submitted by the other
appraiser, the Market Rate shall be the average of such determinations. If the
determination of the Market Rate submitted by one of the appraisers is greater
than one hundred fifteen percent (115%) of the determination of the Market Rate
submitted by the other appraiser, the appraisers shall, within five (5) days of
notice from either Landlord or Tenant, appoint a third appraiser with similar
qualifications to make a determination of the Market Rate. The third appraiser
shall be instructed to complete the appraisal procedure and to submit a written
determination of the Market Rate to Landlord and Tenant within thirty (30) days
after such appraiser's appointment.

            The determination which is neither the highest nor the lowest of the
three determinations shall be binding upon Landlord and Tenant as the Market
Rate unless two determinations are the same, in which event the Market Rate
shall be such amount. Landlord and Tenant shall each bear the costs of their
respective appraisers. The expenses of the third appraiser shall be borne
one-half (1/2) by Landlord and one-half (1/2) by Tenant. "Market Rate" shall
mean


                                       6
<PAGE>

what a Landlord under no compulsion to lease the Premises and a Tenant under no
compulsion to lease the Premises would determine as the Basic Rental, given the
other provisions of the Lease which remain applicable to the parties.
Notwithstanding anything to the contrary contained in this paragraph 8, in no
event shall the Basic Rental for the renewal term be less than the Basic Rental
in effect at the end of the last year of the term of the Lease. In the event the
Market Rate has not been determined by the commencement of the renewal term, the
Tenant shall pay Basic Rental equal to one hundred twenty percent (120%) of the
Basic Rental in effect at the end of the last year of the term of the Lease,
until the Market Rate is determined and promptly after such determination, the
parties shall make an appropriate adjustment to reconcile any overpayments or
under payments of Basic Rental made prior to the determination of the Market
Rate.

      9. Tenant shall have an option to terminate the Lease with respect to that
portion of the Premises, consisting of 11,650 square feet, as shown on Exhibit A
(the "Released Space"). The option to terminate the Lease as to the Released
Space shall be effective, if at all, on April 30, 2003 and shall be effective
only if Tenant delivers written notice of termination to Landlord, which notice
must be given on or before October 31, 2002 and Tenant must deliver with such
notice a cashier or certified check payable to Landlord in an amount (the
"Termination Fee") equal to three (3) times the monthly Basic Rental which would
have been due for the month of April 2003, had Tenant not exercised such
termination option. (For instance, if the Basic Rental due for the month of
April 2003 were $32,894.86, the Termination Fee would be $98,684.58.) The
Termination Fee shall be non-refundable and Landlord shall be entitled to keep
the full amount of the Termination Fee, regardless of whether or not Landlord
re-leases the Released Space or any parts thereof. Any purported exercise of
Tenant's option to terminate which does not strictly comply with the terms set
forth above shall, at Landlord's election, be ineffective.

      If Tenant effectively exercises its option to terminate the Lease as to
the Released Space, then, effective May 1, 2003, (i) the Released Space shall no
longer be leased from Landlord to Tenant, shall no longer be a portion of the
Premises and Tenant shall have relinquished any right or interest to such space,
(ii) Tenant shall vacate the Released Space and deliver it to Landlord in the
condition the Premises are to be delivered at the conclusion of the term, and
(iii) there will be a pro rata downward adjustment in the amount of Basic Rental


                                       7

to be paid for the balance of the Lease term, as well as a pro rata downward
adjustment in the amount of Tenant's proportionate share for all purposes of the
Lease, including those specifically mentioned in paragraph 5 above. The
foregoing notwithstanding, any obligations of Tenant relating to such space,
that accrued prior to May 1, 2003, shall remain in effect.

      The option to terminate granted to Tenant is personal to Tenant and may
not be exercised or be assigned, voluntarily or otherwise, by or to any person
or entity other than Tenant without the prior written consent of Landlord.
Additionally, at Landlord's option, the option to terminate shall be null and
void if, either at the time Tenant exercises such option or at the time such
termination is to become effective, Tenant is in default under any provision of
the Lease.

      10. Notwithstanding anything to the contrary contained in this Amendment,
this Amendment and Landlord's obligations hereunder shall be contingent upon
Landlord having obtained a fully executed lease for not less than 34,956 square
feet of space within the Improvements with Earthshell Corporation, a Delaware
corporation ("Earthshell"), which lease shall be satisfactory to Landlord in its
sole and absolute discretion in all respects. In the event Landlord fails to
obtain such a lease within fifteen (15) days after the execution of this
Amendment, then, Landlord shall have the right, at any time within fifteen (15)
days after such date, by written notice to Tenant, to declare this Amendment
null and void, in which event this Amendment shall be and become null and void
and the rights and obligations with respect to the parties shall be determined
by the Lease, as if this Amendment had never been executed.

      11. In the event and only in the event that this Amendment is fully
executed and delivered and becomes effective (i.e., is not terminated pursuant
to paragraph 9 above), Landlord agrees to pay Ryan Commercial LLC (the "Broker")
a leasing commission on account of this Amendment in the amount specified in a
separate written agreement between Landlord and the Broker. Tenant represents
and warrants to Landlord that it has not dealt with any other realtor, broker or
person that might claim a commission or fee in connection with this Amendment
other than the Broker and shall indemnify, defend and hold harmless Landlord
from and against any claim, loss, cost, damage or expense (including attorneys'
fees) incurred if such representation or warranty shall not be true and correct.


                                       8

      12. Tenant represents and warrants to Landlord that Osicom Technologies,
Inc., a Delaware corporation, is the same entity as Case/Datael, Inc. , a
Delaware corporation, but merely reflects a name change, and that this Amendment
has been duly authorized by all necessary corporate action of Tenant and is the
valid, binding and enforceable act of Tenant.

      13. By its execution of this Amendment, Tenant hereby certifies and
represents to Landlord that Landlord is in compliance with all of the terms,
covenants and conditions of the Lease and Tenant has no claim or cause of action
against or with respect to Landlord or its agents, employees or contractors
arising out of or in any way connected with the Lease or the use of the
Premises.

      14. Capitalized terms not defined in this Amendment shall have the
meanings ascribed to those terms in the Lease.

      15. Except as set forth herein, the Lease remains in full force and effect
and unmodified.

      16. Time is of the essence of all provisions of this Amendment and remains
of the essence of all provisions of the Lease.

      17. The provisions of this Amendment shall bind and inure to the benefit
of the parties hereto and their respective successors and permitted assigns.

            IN WITNESS WHEREOF the parties hereto have executed under seal this
Amendment on the day and year first written above.

16.02 Waiver of Rights.

      Landlord and Tenant each hereby waive all claims, causes of action and
rights of recovery against the other and their respective partners, agents,
officers and employees, for any damage to or destruction of persons, property or
business which shall occur on or about the Premises and shall result from any of
the perils insured under any and all policies of insurance maintained by
Landlord and Tenant, regardless of cause, including the negligence and
intentional wrong doing of either party and their respective agents, officers
and employees but only to the extent of recovery, if any under such policy or
policies of insurance; provided however, that this waiver shall be invalidated
by reason of this waiver.

<PAGE>
                              Damage of Destruction

17.01 Substantial Damage

      If the Building or any part thereof shall be damaged by fire or other
casualty to the extent that substantial alteration or reconstruction of the
Building shall, in Landlord's reasonable opinion, be required (whether or not
the Premises shall have been damaged) or if the proceeds of insurance are
required to be used to retire the mortgage debt, Landlord may, at its option,
terminate this Lease by notifying Tenant in writing of such termination within
sixty (60) days after the date of such damage. If this Lease is so terminated,
Rent shall be abated as of the date of such damage.

17.02 Restoration.

      If Landlord does not terminate this Lease pursuant to Section 17.01,
Landlord shall, within seventy-five (75) days after receipt by Landlord of the
Proceeds payable in respect of such fire or other casualty, proceed with
reasonable diligence to repair and restore the Building (subject to Force
Majeure) to substantially the same condition in which it was immediately prior
to the occurrence of the casualty to the extent of Landlord's Work and the value
of Landlord's Contribution. Landlord shall not be required to rebuild, repair,
or replace any part of Tenant's furniture, furnishings or fixtures or equipment.
Landlord shall not be liable for any inconvenience or annoyance to Tenant or
injury to the business of Tenant resulting in any way from such damage or the
repair thereof, except that, Landlord shall allow Tenant an abatement of Rent,
Additional Rent and all other charges payable hereunder during the time and to
the extent the Premises are unfit for the operation of Tenant's business. If
such restoration is not completed within one hundred and twenty (120) days after
the prior casualty, Tenant may terminate this Lease after Landlord is in receipt
of all proceeds.

                                   ARTICLE 18
                                 Eminent Domain

18.01 Total Taking.

      If the Premises or the Building should be the subject of a Total Taking,
then this Lease shall terminate as of the date when physical possession of the
Building or the Premises is taken by the condemning Governmental Authority.

18.02 Partial Taking.

If there occurs a Partial Taking, Landlord (whether or not the Premises are
affected thereby) may terminate this Lease by giving written notice thereof to
Tenant within sixty (60) days after the right of election accrues, in which
event this Lease shall terminate as of the date the Building or Premises is
taken by the condemning authority. If upon such Partial Taking this Lease is not
terminated, Rent shall be abated by an amount representing that part of the Rent
properly allocable to the portion of the Premises so taken and Landlord shall,
at Landlord's sole expense, restore and reconstruct the Building and the
Premises to substantially their former condition to the extent that the same, in
Landlord's judgement, may be feasible, but such work shall not exceed the scope
of Landlord's Work and the value of Landlord's Contribution. The Landlord shall
have no liability for interruption of Tenant's business. If such restoration is
not completed with one hundred and twenty (120) days after such Partial Taking,
Tenant may terminate this Lease.

18.03. Awards and Proceeds.
<PAGE>

      All Proceeds payable in respect of Taking shall be the property of
Landlord. Tenant hereby assigns to Landlord all rights of Tenant in or to such
Proceeds, provided that Tenant shall be entitled to separately petition the
condemning authority for a separate award for its moving expenses and trade
fixtures but only if such a separate award will not diminish the amount of
Proceeds payable to Landlord.

                                   ARTICLE 19
                                 Quiet Enjoyment

19.01 Landlord's Covenant.

      Provided that an Event of Default has not occurred and is not then
continuing, Tenant shall, subject to the Permitted Exceptions, quietly have and
enjoy the Premises during the Lease Term, without hindrance or molestation from
any Person lawfully claiming by, through or under Landlord. Landlord represents
that it has good and marketable title to the Land, the Building and the
Premises, that the Permitted Use is allowed by law and that the Permitted
Exceptions win not interfere with Tenant's Permitted Use.

19.02 Subordination

      This Lease is and shall be subject and subordinate to any mortgage now or
hereafter on the Building and to each advance made or hereafter to be made under
any mortgage, and to all renewals, modifications, consolidations, replacements
and extensions thereof and all substitutions therefore. This Section 19.02 shall
be self-operative and no further instrument of subordination shall be required.
In confirmation of such subordination, Tenant shall execute and deliver promptly
(within ten (10) days of receipt) any certificate that Landlord or any mortgagee
may request. In the event that any mortgagee shall succeed to the interest of
Landlord then this Lease shall terminate, or, at the option of such mortgagee,
this Lease shall nevertheless continue in full force and effect and Tenant shall
and does hereby agree to attorn to such mortgagee and to recognize such
mortgagee as its Landlord.

19.03 Notice to Mortgagee.

      No act or failure to act on the part of Landlord which would entitle
Tenant under the terms of this Lease, or by law, to be relieved of Tenant s
obligations hereunder or to terminate this Lease, shall result in a release or
termination or such obligations or a termination of this Lease unless (i) Tenant
shall have first given written notice of Landlord's act or failure to act to
Landlord's mortgagees of record, whose identity has been furnished to Tenant in
writing, if any, specifying the act or failure to act on the part of Landlord
which could or would give basis to Tenant's rights; and (ii) such mortgagees,
after receipt of such notice, have had the opportunity to cure such default
within the same time period as applicable to Landlord; but nothing contained in
this Section 19.03 shall be deemed to impose any obligation on any such
mortgagees to correct or cure any such condition. "Reasonable time" as used
above shall mean a period of not less than thirty (30) Business Days and shall
include (but not be limited to) a reasonable time to obtain possession of the
Building if the mortgagee elects to do so and a reasonable time to correct or
cure the condition if such condition is determined to exist.

19.04 Other Provisions Regarding Mortgagees.

      If this Lease or the Rent due hereunder is assigned to a mortgagee as
collateral security for a loan, no such mortgagee shall be deemed to have
assumed any of Landlord's obligations hereunder solely as a result of said
assignment. A mortgagee to whom this Lease has been so assigned shall be deemed
to have assumed such obligations only if (i) by the terms of the instrument of
assignment such mortgagee specifically elects to assume such obligations or (ii)
such mortgagee has (a) foreclosed its mortgage, (b) accepted a deed in lieu
thereof, or (c) taken possession of the Premises by entry or otherwise. Even if
such mortgagee assumes the obligations of Landlord hereunder, (i) any such
obligation under Section 24.01 to return the Security Deposit to the Tenant
shall be limited to the amount actually received by the mortgagee
<PAGE>

with respect thereto, and (ii) such mortgagee will be liable for breaches of any
Landlord's obligations hereunder only to the extent such breaches occur during
the period of ownership by the mortgagee after foreclosure (or any conveyance by
a deed in lieu thereof), all as set forth in Section 25.10. hereof. Tenant may
from time to time, at mortgagees request, be required to provide mortgagee with
certain financial information pertaining to the Tenant as mortgagee may
reasonably request.

20.01 Defaults.

      The following will (i) if any requirement for notice or lapse of time has
not been met, constitute Defaults, and (ii) if there are no such requirements or
if such requirements have been met, constitute Events of Default

      (a) The failure of Tenant to pay Rent when due, and the continuation of
      the failure for a period of ten (10) days;

      (b) The failure of Tenant to perform any of its obligations under this
      Lease, other than its obligation to pay Rent, and the continuation of the

      specifying in reasonable detail the nature of the failure;

      (c) The failure of Tenant to pay Rent when due or to perform any of its
      obligations under this Lease, if Landlord has given Tenant notice of the
      same or similar failure at least three times during the term proceeding
      the date on which the Rent or performance was due.

      (d) The occurrence with respect to Tenant or any Guarantor of one or more
      of the following events: the death, dissolution, termination of existence

      receiver for an or substantially all of its property, the making of a
      fraudulent conveyance or the execution of an assignment or trust mortgage
      for the benefit of creditors by it, or the filing of a petition of
      bankruptcy or the commencement of any proceedings by or against it under a
      bankruptcy, insolvency or other law relating to the relief or the
      adjustment of indebtedness, rehabilitation or reorganization of debtors;
      provided that if such petition or commencement is involuntarily made
      against it and is dismissed within sixty (60) days of the date of such
      filing or commencement, such events will not constitute an Event of
      Default;

      (e) The issuance of any execution or attachment against Tenant or any
      other occupant of the Premises as a result of which the Premises are taken
      or occupied by a Person other than Tenant; and

      (f) The cancellation of, refusal to review or denial of liability under
      any insurance policy relating to the Premises as a result of the Premises
      being unoccupied.

20.02 Tenant's Best Efforts.

      In the event that the Default of which Landlord gives notice is of such a
nature that it cannot be cured within such twenty (20) day period, then such
Default shall not be deemed to be an Event of Default so long as Tenant, after
receiving such notice, proceeds to cure the Default as soon as reasonably
possible and continues to take all steps necessary to complete the same within a
period of time which, under all prevailing circumstances, shall be reasonable.
No Default shall be deemed to be an Event of Default if and
<PAGE>

so long as Tenant shall be so proceeding to cure the same in good faith or be
delayed in or prevented from curing the same by reason of Force Majeure.

20.03 Tenant's Default - Rent Abatement Cancellation.

      If an Event of Default occurs at any time during the term of this Lease,
Landlord shall have the option of retracting the full rent abatement, if any,
and Tenant shall pay the full abated amount immediately to Landlord upon demand.

21.01

In the event that Tenant shall become a debtor under the Bankruptcy Code, and
the trustee or Tenant shall elect to assume this Lease for the purposes of
assigning the same or otherwise, such election and assignment may only be made
if all the terms and conditions of Sections 21.02 and 21.03 hereof are
satisfied. If such trustee shall fail to elect to assume this Lease within sixty
(60) days after the filing of the petition, this Lease shall be deemed to have
been rejected. Landlord shall be thereupon immediately entitled to possession of
the Premises without further obligation to Tenant or the trustee, and this Lease
shall be terminated, but the Landlord's right to be compensated for damages both
at law and as provided in ARTICLE 20 hereof in such case shall survive.

21.02

A. No election by the trustee or debtor-in-possession to assume this lease,
whether under Chapter 7, 11 or 13 of the Bankruptcy Code, unless otherwise
ordered by the Bankruptcy Court, shall be effective unless each of the following
conditions, which Landlord and Tenant acknowledge and agree are commercially
reasonable in the context of a bankruptcy case of Tenant, have been satisfied,
and Landlord has so acknowledged in writing:

(1)   The trustee or the debtor-in-possession has cured, or has provided
      Landlord adequate assurance (as hereinafter defined) that:

(a)   Within ten (10) days from the date of such assumption, the trustee will

(b)   Within thirty (30) days from the date of such assumption, the trustee will
      cure all nonmonetary defaults under this Lease.

(2)   The trustee or debtor-in-possession has compensated, or has provided to
      Landlord adequate assurance (as hereinafter defined) that within ten (10)
      days from the date of assumption, Landlord will be compensated for any
      pecuniary loss incurred by Landlord arising from the default of Tenant,
      trustee, or the debtor-in possession as recited in Landlord's written
      statement of pecuniary loss sent to the trustee or debtor-in-possession.

(3) The trustee or the debtor-in-possession has provided Landlord with adequate
assurance (as hereinafter defined) of the future performance of each of Tenant's
the trustee's or debtor-in possession's obligations under this Lease, Provided,
however, that:

(a) Whether or not otherwise required by the terms of this Lease, the trustee or
debtor-in-possession shall also pay in advance on the date minimum rent is
payable hereunder, one twelfth (1/12th) of Tenant's annual obligations under
this Lease for Operating Expenses, Taxes, and any other charges payable
hereunder;
<PAGE>

      (b) From and after the date of the assumption of this Lease, the trustee
or debtor-in possession shall pay as annual minimum rent the amount equal to the
sum of the annual minimum rent otherwise payable hereunder; and

      (c) The obligations imposed upon the trustee or debtor-in-possession under
this Lease shall continue with respect to Tenant or any assignee of this Lease
after the completion of the bankruptcy case, subject to any further and/or
increased obligations, which thereafter are imposed by any provisions of this
Lease.

(4) The assumption of this Lease will not breach any provision in this Lease or
any other lease, mortgage, financing agreement or other agreement by which
Landlord is bound relating, to the Building.

(5) The assumption has been ratified and approved by order of such court or
courts as have jurisdiction under the Bankruptcy Code.

assurance" shall mean (unless otherwise determined by the Bankruptcy Court):

(1) The trustee or debtor-in-possession has and will continue to have sufficient
unencumbered assets after the payment of all secured obligations and
administrative expenses to assure Landlord that the trustee or
debtor-in-possession will have sufficient funds to fulfill the obligations of
Tenant under this Lease; and

(2) The Bankruptcy Court or such court as is exercising jurisdiction over the
Bankruptcy Code shall have entered an order segregating sufficient cash payable
to Landlord and/or the trustee or debtor-in-possession, acceptable as to value
and kind to the Landlord, to secure to Landlord the obligation of the trustee or
debtor-in-possession to cure any monetary and/or nonmonetary defaults under this
Lease within the time periods set forth above.

Section 21.03

If the trustee or debtor-in-possession has assumed this Lease pursuant to the
terms and provisions of Section 21.01 and 21.02 hereof, for the purpose of
assigning (or elects to assign) Tenant's interest under this Lease, or the
estate created thereby, to any other person, such interest or estate may be so
assigned only if Landlord shall acknowledge in writing that the intended
assignee has provided adequate assurance of the future performance (as defined
in this Section 21.03) of all the terms, covenants and conditions of this Lease
to be performed by Tenant.

future performance" shall mean (unless otherwise determined by the Bankruptcy
Court) that each of the following conditions have been satisfied, and Landlord

certified public accountant which shows a net worth and working capital in
amounts (which amounts shall in no event be less than the greater those of

execution of this lease) determined to be sufficient by Landlord to assure the
future performance of such assignee of Tenant's obligations under this Lease;

(2) Landlord has obtained all consents and waivers from any third party required
under any lease, mortgage, financing arrangement or other agreement by which
Landlord is bound to permit Landlord to consent to such assignment;

forth in this Lease for an assignment of Tenant's interest in this Lease or the
estate created thereby; and

(4) The Assignee has deposited with Landlord a security deposit in such amount
as determined by Landlord to be appropriate based upon the financial information
supplied under this Section 21.03.

Section 21.04

      When, pursuant to the Bankruptcy Code, the trustee or debtor-in-possession
shall be obligated to pay reasonable use and occupancy charges for the use of
the Premises or any portion thereof, such charges shall not be less than the
Rent and any other charges payable by Tenant hereunder unless otherwise
determined by the Bankruptcy Court.

Section 21.05

      The rights and remedies of the Landlord contained in the provisions of
this ARTICLE 21 are and shall be deemed to be in addition to, and not in
limitation of, applicable provisions of ARTICLE 20 and ARTICLE 22 and other
provisions hereof, or any other rights which the Landlord may have under
applicable statutory or case law. Whenever any of the terms or provisions of
this Lease, including, without limitation, rental obligations, are modified
pursuant to the provisions of this ARTICLE 21, upon Landlord's request the
parties hereto promptly shall execute, acknowledge and deliver a written
instrument evidencing and confirming the same. In no event shall this Lease, if
the term hereof has expired or has been terminated in accordance with the
provisions hereof, be revived, and no stay or other proceeding shall nullify,
postpone or otherwise affect the expiration or earlier termination of the term
of this Lease pursuant to the provisions of ARTICLE 20 and ARTICLE 22 hereof or
prevent Landlord from regaining possession of the Premises thereupon.

                     Landlord's Remedies; Damages on Default

22.01 Landlord's Remedies.

      If an Event of Default shall occur and be continuing, Landlord may, at its
option, give to Tenant a notice terminating this Lease upon a date specified in
such notice, which date shall be not less than three (3) Business Days after the
date of receipt by Tenant of such notice from Landlord, and upon the date
specified in said notice, the term and estate hereby vested in Tenant shall
cease and any and all other right, title and interest of Tenant hereunder shall
likewise cease without further notice or lapse of time, as fully and with like
effect as if the entire Lease Term had elapsed, but Tenant shall continue to be
liable to Landlord as hereinafter provided.

If such Event of Default results from Tenants failure to pay Tenant's Cost as
required by Section 7.01 hereof and the Work Letter, Landlord may, at its
option, in addition to or in lieu of the other remedies available to Landlord,
refuse Tenant access to the Premises. In such event the Term Commencement Date
shall be the earlier of (i) the date determined in accordance with Section 7.04
or (ii) the Substantial Completion Date.

      If such Event of Default results from Tenant's failure to pay a charge for
an Additional Service pursuant to Section 8.03 hereof, Landlord may, without
further notice to Tenant, discontinue any or all of such Additional Services.

      If an Event of Default shall occur and be continuing, Landlord shall be
relieved of its undertakings under Article 13 hereof.
<PAGE>

22.02 Surrender.

      Upon any termination of this Lease as the result of an Event of Default,
Tenant shall quit and peacefully surrender the Premises to Landlord, upon or at
any time after any such termination, Landlord may without further notice enter
the Premises and possess itself thereof by summary proceedings or otherwise, any
may dispossess Tenant and remove Tenant and all other Persons and property from
the Premises and may have, hold and enjoy the Premises and the right to receive
all rental income of and from the same.

22.03 Right to Relet.

      At any time from time to time after any such termination, Landlord may
relet the Premises or any part thereof, in the name of Landlord or otherwise,
for such terms or terms (which may be greater or less than the period which
would otherwise have constituted the balance of the Lease Term) and on such
conditions (which may include concessions or free rent) as Landlord, in its
reasonable discretion, may determine and may collect and receive the rents
therefor. Landlord shall in no way be responsible or liable for any failure to
relet the Premises or any part thereof, or for any failure to collect any rent
due upon any such reletting. Landlord shall use reasonable efforts to relet the
Premises and mitigate damages.

22.04 Survival of Covenants.

      No such termination of this Lease shall relieve Tenant of its liability
and obligations under this Lease and such liability and obligations shall
survive any such termination. Tenant shall indemnify and hold Landlord harmless
from all loss, cost, expense, damage or liability arising out or in connection
with such termination.

      In the event of any such termination, Tenant shall pay to the Landlord the
Rent up to the date of such termination. Tenant shall also pay to Landlord, on
demand, as and for liquidated and agreed damages for Tenant's Default, the
difference between

      (1)   the aggregate Rent which would have been payable under this Lease by
            Tenant from the date of such termination until the Stated Expiration
            Date, less

      (2)   the fair and reasonable rental value of the Premises for the same
            period discounted to present value, excluding all of Landlord's
            reasonable estimate of expenses to be incurred in connection with
            reletting the Premises, including, without limitation, all repossess
            costs, brokerage commission, legal expenses, reasonable attorney's
            fees, alteration costs, and expenses of preparation for such
            reletting.

      If the Premises or any part thereof are relet by the Landlord before
presentation of proof of such liquidated damages to any court, commission or
tribunal, the amount of rent reserved upon such reletting shall be, prima facie,
the fair and reasonable rental value for the part or the whole of the Premises
so relet during the term of the reletting.

      Nothing herein contained shall limit or prejudice the right of the
Landlord to prove and obtain as liquidated damages by reason of such
termination, an amount equal to the maximum allowed by any statute of rule of
law in effect at the time when, and governing the proceedings in which, such
damages are to be proved, whether or not such amount be greater, equal to, or
less than the amount of the difference referred to above.

22.05 Right to Equitable Relief.
<PAGE>

      If there shall occur a Default or threatened Default, Landlord shall be
entitled to enjoin such Default or threatened Default and shall have the right
to invoke any right and remedy allowed at law or in equity or by statute or
otherwise as though re-entry, summary proceedings, and other remedies were not
provided for in this Lease.

22.06 Right to Self Help; Interest on Overdue Rent.

      If an Event of Default shall occur and be continuing, Landlord shall have
the right, but shall not be obligated, to enter upon the Premises and to perform
such obligation notwithstanding the fact that no specific provision for such
substituted performance by Landlord is made in this Lease with respect to such
Default In performing such obligation, Landlord may make any payment of money or
perform any other act. The aggregate of (i) all sums so paid by Landlord, (ii)
interest (at the rate of 11/2% per month or the highest rate permitted by law,
whichever is less) on such sum plus all Rent not paid when due and (iii) all
necessary incidental costs and expenses in connection with the performance of.
any such act by Landlord,. shall be deemed to be Rent under this Lease and shall
be payable to Landlord immediately upon demand. Landlord may exercise the
foregoing rights without waiving any other of its rights or releasing Tenant
from any of its obligations under this Lease.

23.01 No Waivers.

      Failure of Landlord to complain of any act or omission on the part of
Tenant no matter how long the same may continue, shall not be deemed to be a
waiver by Landlord of any of its rights hereunder. No waiver of any provision of
this Lease shall be deemed a waiver of a breach of the same or any other
provision. No acceptance by Landlord of any partial payment shall constitute an
accord or satisfaction but shall only be deemed a partial payment on account.

                                Security Deposit

24.01 Security Deposit

      Tenant has deposited the Security Deposit with Landlord. Landlord shall
hold the Security Deposit as security for the full and faithful payment or
performance by Tenant of its obligations under this Lease and not as a
prepayment of Rent. Landlord may commingle the Security Deposit with other funds
of Landlord but shall not be liable to Tenant for the payment of interest
thereon or profits therefrom. Landlord may expend such amounts from the Security
Deposit, including legal fees, as may be necessary to cure any Default and, in
such case, Tenant shall pay to Landlord the amount so expended, on demand, after
written notice from Landlord specifying the application of the spent funds.
Landlord shall assign the Security Deposit to any subsequent owner of the
Building and thereafter Landlord shall have no further liability to Tenant with
respect thereto.

delay and the period for the performance of any such act shall be extended for a
period equivalent to the period of such delay.

competitive.

         3. Prices:

                    A. Osicom shall pay to NSI for all NSI Products delivered
hereunder an amount equal to the price as identified on Schedule A attached
hereto. The price for the NSI Product shall increase or decrease in proportion

percentage for each unit, provided, however, that NSI shall not offer to sell or
sell any NSI Product at a lower price or upon more favorable terms than the

Payment shall be due on a net cash basis thirty (30) days from the billing date.

         5. Delivery of Products: Each party will provide products in accordance
with their usual and customary methods. Orders will be received in accordance
with each party's usual and customary procedures for accepting orders, which
procedures have been communicated to by NSI to Osicom and by Osicom to NSI and
may change from time to time in either party's reasonable discretion. In the
event that either party orders any products in quantities substantially greater
or less than the quantities normally ordered, such order must be placed in time
as will reasonably permit the supplying party to fulfill that order (if greater)
or to dispose of any excess quantity of product (if lesser) which the supplying
party may have obtained.

         6. Force Majeure: Each party shall not be liable for any failure to
deliver products if such failure has been occasioned by the occurrence of any
act of war, fire, accident, casualty, embargo, strike, civil commotion,
government prohibitions or pre-emptions, failure of any supplier to supply
necessary products or ingredients, labor difficulties, equipment malfunction,
shortages of ingredients, fuel or energy, or any other circumstance beyond such
party's control.

pay, and which arise out of Indemnifying Party's negligence or willful
misconduct.

may be changed or waived only in writing. Waiver of a breach of this Agreement
shall not operate as a waiver of any other breach. This Agreement is binding
upon and inures to the benefit of the parties hereto and their successors and
assigns. Invalidity of any provision of this Agreement shall not affect other

6.       The parties acknowledge that in connection with the assignment of the
         Assigned Products, certain mutually agreeable employees will cease
         performing services for NSI and shall thereafter perform services for
         Osicom (the "Transferred Employees"). Transferred Employees shall be
         transferred to Osicom's payroll as of July 31, 1998. However,
         Transferred Employees shall remain on NSI's health insurance plan. NSI
         will forward an invoice each month to Osicom which shall indicate the
         amount of premium payment made by NSI with respect to such Transferred
         Employees as well as documentation of their continued coverage under
         NSI's health plan. Payment shall be due from Osicom to NSI on a net
         cash basis thirty (30) days from the billing date. Notwithstanding
         anything to the contrary in this Agreement, the terms of this Section 5
         shall survive the termination of this Agreement.

7.       Osicom shall provide to NSI certain MIS computer services at NSI place
         of business at Waltham, Massachusetts, including, without limitation,
         the maintenance of data lines. In consideration for such services, NSI
         shall pay to Osicom the sum of one thousand dollars ($1,000) per month,
         payable on the first day of each calendar month as long as NSI requires
         such services.

8.       Osicom and NSI agree that Osicom shall have co-ownership of the
         intellectual property listed on Schedule C attached hereto (the
         "Intellectual Property"), completed as of the commencement of the
         Rights Offering, for Osicom's product development needs, provided,
         however, that the Intellectual Property shall become a part of a
         value-added Osicom product provided, further that Osicom shall not
         resell, license, transfer or assign to any third party all or any part
         of the Intellectual Property or any derivative thereof.

9.       The term of this Agreement shall be for a period of twelve (12) months
         from the date set forth above. This Agreement may be sooner terminated
         only upon the written agreement of both parties hereto.

10.      The invalidity or unenforceability of any provision of this Agreement
         shall not affect the validity or enforceability of any other provisions
         of this Agreement, which shall remain in full force and effect.

11.      Notices given under this Agreement shall be in writing, and shall be
         deemed given when delivered by a recognized overnight service, or three
         (3) days after deposit by certified mail, return receipt requested,
         addressed to a party at the address given above, or to another address
         specified by a party.

12.      This Agreement shall be governed by Massachusetts law. The parties
         consent to exclusive jurisdiction of courts sitting in Massachusetts
         for all disputes arising under this Agreement. Service of process is
         effective if served in the manner a notice may be given under this
         Agreement.

13.      Neither NSI nor Osicom shall assign this Agreement to any other person
         or entity, without the prior written consent of the other party,
         provided, however, that Osicom may assign all or part of this Agreement
         to any of its subsidiaries without the prior consent of NSI.

14.      This Agreement contains the entire understanding of the parties and may
         be changed or waived only in writing. Waiver of a breach of this
         Agreement shall not operate as a waiver of any other breach. This
         Agreement is binding upon and inures to the benefit of the parties
         hereto and their successors and assigns. Invalidity of any provision of
         this Agreement shall not affect other provisions.

         IN WITNESS WHEREOF, the parties have executed this Agreement as of the
day and year first set forth above

          entirety by Schedule C attached to this letter and made a part hereof.

                                  EXHIBIT 10.25
                           Loan and Security Agreement

Borrower:         Cray Communications, Inc., a Delaware corporation
Address:          2800 28th Street, Suite 100
                  Santa Monica, California 90405

Date:             September 27, 1996

THIS LOAN AND SECURITY AGREEMENT is entered into on the above date between COAST
BUSINESS CREDIT, a division of Southern Pacific Thrift & Loan Association
("Coast"), a California corporation, with offices at 12121 Wilshire Boulevard,
Suite 1111, Los Angeles, California 90025, and the borrower named above
("Borrower"), whose chief executive office is located at the above address
("Borrower's Address"). The Schedule to this Agreement (the "Schedule") shall
for all purposes be deemed to be a part of this Agreement, and the same is an
integral part of this Agreement. (Definitions of certain terms used in this
Agreement are set forth in Section 8 below.)


                                      -1-
<PAGE>

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

            1.    LOANS.

            1.1 Loans. Coast will make loans to Borrower (the "Loans"), in
amounts determined by Coast in its sole discretion, up to the amounts (the
"Credit Limit") shown on the Schedule, provided no Default or Event of Default
has occurred and is continuing.

            1.2 Interest. All Loans and all other monetary Obligations shall
bear interest at the rate shown on the Schedule, except where expressly set
forth to the contrary in this Agreement. Interest shall be payable monthly, on
the last day of the month. Interest may, in Coast's discretion, be charged to
Borrower's loan account, and the same shall thereafter bear interest at the same
rate as the other Loans. Regardless of the amount of Obligations that may be
outstanding from time to time, Borrower shall pay Coast minimum monthly interest
during the term of this Agreement with respect to the Receivable Loans and the
Inventory Loans in the amount set forth on the Schedule (the "Minimum Monthly
Interest").

            1.3 Fees. Borrower shall pay Coast the fee(s) shown on the Schedule,
which are in addition to all interest and other sums payable to Coast and are
not refundable.

            2.  SECURITY INTEREST.

            2.1 Security Interest. To secure the payment and performance of all
of the Obligations when due, Borrower hereby grants to Coast a security interest
in all of Borrower's interest in the following, whether now owned or hereafter
acquired, and wherever located: All Receivables, Inventory, Equipment, and
General Intangibles, including, without limitation, all of Borrower's Deposit
Accounts, and all money, and all property now or at any time in the future in
Coast's possession (including claims and credit balances), and all proceeds of
any of the foregoing (including proceeds of any insurance policies, proceeds of
proceeds, and claims against third parties), all products of any of the
foregoing, and all books and records related to any of the foregoing (all of the
foregoing, together with all other property in which Coast may now or in the
future be granted a lien or security interest, is referred to herein,
collectively, as the "Collateral").

            3.  REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE BORROWER.

            In order to induce Coast to enter into this Agreement and to make
Loans, Borrower represents and warrants to Coast as follows, and Borrower
covenants that the following representations will continue to be true, and that
Borrower will at all times comply with all of the following covenants:

            3.1 Corporate Existence and Authority. Borrower, if a corporation,
is and will continue to be, duly organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation. Borrower is
and will continue to be qualified and licensed to do business in all
jurisdictions in which any failure to do so would have a material adverse effect
on Borrower. The execution, delivery and performance by Borrower of this
Agreement, and all other documents contemplated hereby (i) have been duly and
validly authorized, (ii) are enforceable against Borrower in accordance with
their terms (except as enforcement may be limited by equitable principles and by
bankruptcy, insolvency, reorganization, moratorium or similar laws relating to
creditors' rights generally), and (iii) do not violate Borrower's articles or
certificate of incorporation, or Borrower's by-laws, or any law or any material
agreement or instrument which is binding upon Borrower or its property, and (iv)
do not constitute grounds for acceleration of any material indebtedness or
obligation under any material agreement or instrument which is binding upon
Borrower or its property.

            3.2 Name; Trade Names and Styles. The name of Borrower set forth in
the heading to this Agreement is its correct name. Listed on the Schedule are
all prior names of Borrower and all of Borrower's present and prior trade names.
Borrower shall give Coast 10 days' prior written notice before changing its name
or doing business under any other name. Borrower has complied, and will in the
future comply, with all laws relating to the conduct of business under a
fictitious business name.

            3.3 Place of Business; Location of Collateral. The address set forth
in the heading to this Agreement is Borrower's chief executive office. In
addition, Borrower has places of business and Collateral is located only at the
locations set forth on the Schedule. Borrower will give Coast at least 30 days
prior written notice before opening any additional place of business, changing
its chief executive office, or moving any of the Collateral to a location other
than Borrower's Address or one of the locations set forth on the Schedule.


                                      -1-
<PAGE>

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

            3.4 Title to Collateral; Permitted Liens. Borrower is now, and will
at all times in the future be, the sole owner of all the Collateral, except for
items of Equipment which are leased by Borrower. The Collateral now is and will
remain free and clear of any and all liens, charges, security interests,
encumbrances and adverse claims, except for Permitted Liens. Coast now has, and
will continue to have, a first-priority perfected and enforceable security
interest in all of the Collateral, subject only to the Permitted Liens, and
Borrower will at all times defend Coast and the Collateral against all claims of
others. None of the Collateral now is or will be affixed to any real property in
such a manner, or with such intent, as to become a fixture. Borrower is not and
will not become a lessee under any real property lease pursuant to which the
lessor may obtain any rights in any of the Collateral and no such lease now
prohibits, restrains, impairs or will prohibit, restrain or impair Borrower's
right to remove any Collateral from the leased premises. Whenever any Collateral
is located upon premises in which any third party has an interest (whether as
owner, mortgagee, beneficiary under a deed of trust, lien or otherwise),
Borrower shall, whenever requested by Coast, use its best efforts to cause such
third party to execute and deliver to Coast, in form acceptable to Coast, such
waivers and subordinations as Coast shall specify, so as to ensure that Coast's
rights in the Collateral are, and will continue to be, superior to the rights of
any such third party. Borrower will keep in full force and effect, and will
comply with all the terms of, any lease of real property where any of the
Collateral now or in the future may be located.

            3.5 Maintenance of Collateral. Borrower will maintain the Collateral
in good working condition, and Borrower will not use the Collateral for any
unlawful purpose. Borrower will immediately advise Coast in writing of any
material loss or damage to the Collateral.

            3.6 Books and Records. Borrower has maintained and will maintain at
Borrower's Address complete and accurate books and records, comprising an
accounting system in accordance with generally accepted accounting principles.

            3.7 Financial Condition, Statements and Reports. All financial
statements now or in the future delivered by Borrower to Coast have been, and
will be, prepared in conformity with generally accepted accounting principles
(except, in the case of unaudited financial statements, for the absence of
footnotes and subject to normal year-end adjustments) and now and in the future
will fairly reflect the financial condition of Borrower, at the times and for
the periods therein stated. Between the last date covered by any such statement
provided to Coast and the date hereof, there has been no material adverse change
in the financial condition or business of Borrower. Borrower is now and will
continue to be solvent.

            3.8 Tax Returns and Payments; Pension Contributions. Borrower has
timely filed, and will timely file, all tax returns and reports required by
foreign, federal, state and local law, and Borrower has timely paid, and will
timely pay, all foreign, federal, state and local taxes, assessments, deposits
and contributions now or in the future owed by Borrower. Borrower may, however,
defer payment of any contested taxes, provided that Borrower (i) in good faith
contests Borrower's obligation to pay the taxes by appropriate proceedings
promptly and diligently instituted and conducted, (ii) notifies Coast in writing
of the commencement of, and any material development in, the proceedings, and
(iii) posts bonds or takes any other steps required to keep the contested taxes
from becoming a lien upon any of the Collateral. As of the date hereof, Borrower
is unaware of any claims or adjustments proposed for any of Borrower's prior tax
years which could result in additional taxes becoming due and payable by
Borrower. Borrower has paid, and shall continue to pay all amounts necessary to
fund all present and future pension, profit sharing and deferred compensation
plans in accordance with their terms, and Borrower has not and will not withdraw
from participation in, permit partial or complete termination of, or permit the
occurrence of any other event with respect to, any such plan which could result
in any liability of Borrower, including any liability to the Pension Benefit
Guaranty Corporation or its successors or any other governmental agency.

            3.9 Compliance with Law. Borrower has complied, and will comply, in
all material respects, with all provisions of all material foreign, federal,
state and local laws and regulations relating to Borrower, including, but not
limited to, those relating to Borrower's ownership of real or personal property,
the conduct and licensing of Borrower's business, and environmental matters.

            3.10 Litigation. Except as disclosed in the Schedule, there is no
claim, suit, litigation, proceeding or investigation pending or (to best of
Borrower's knowledge) threatened by or against or affecting Borrower in any
court or before any governmental agency (or any basis therefor known to
Borrower) which may result, either separately or in the aggregate, in any
material adverse change in the financial condition or business of Borrower, or
in any material impairment in the ability of Borrower to carry on its business
in substantially the same manner as it is now being conducted. Borrower will
promptly inform Coast in writing of any claim, proceeding, litigation or
investigation in the future threatened or


                                      -2-
<PAGE>

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

instituted by or against Borrower involving any single claim of $50,000.00 or
more, or involving $100,000.00 or more in the aggregate.

            3.11 Use of Proceeds. All proceeds of all Loans shall be used solely
for lawful business purposes. Borrower is not purchasing or carrying any "margin
stock" (as defined in Regulation G of the Board of Governors of the Federal
Reserve System) and no part of the proceeds of any Loan will be used to purchase
or carry any "margin stock" or to extend credit to others for the purpose of
purchasing or carrying any "margin stock."

            4.  Receivables.

            See "Other Provisions" on Schedule.

            4.1 Representations Relating to Receivables. Borrower represents and
warrants to Coast as follows: Each Receivable with respect to which Loans are
requested by Borrower shall, on the date each Loan is requested and made,
represent an undisputed bona fide existing unconditional obligation of the
Account Debtor created by the sale, delivery, and acceptance of goods or the
rendition of services in the ordinary course of Borrower's business.

            4.2 Representations Relating to Documents and Legal Compliance.
Borrower represents and warrants to Coast as follows: All statements made and
all unpaid balances appearing in all invoices, instruments and other documents
evidencing the Receivables are and shall be true and correct and all such
invoices, instruments and other documents and all of Borrower's books and
records are and shall be genuine and in all respects what they purport to be.
All sales and other transactions underlying or giving rise to each Receivable
shall fully comply with all applicable laws and governmental rules and
regulations. All signatures and endorsements on all documents, instruments, and
agreements relating to all Receivables are and shall be genuine, and all such
documents, instruments and agreements are and shall be legally enforceable in
accordance with their terms.

            4.3 Schedules and Documents relating to Receivables. Borrower shall
deliver to Coast transaction reports and loan requests, schedules of
Receivables, and schedules of collections, all on Coast's standard forms;
provided, however, that Borrower's failure to execute and deliver the same shall
not affect or limit Coast's security interest and other rights in all of
Borrower's Receivables, nor shall Coast's failure to advance or lend against a
specific Receivable affect or limit Coast's security interest and other rights
therein. Loan requests received after 10:30 AM (Pacific Time) will not be
considered by Coast until the next Business Day. Together with each such
schedule, or later if requested by Coast, Borrower shall furnish Coast with
copies (or, at Coast's request, originals) of all contracts, orders, invoices,
and other similar documents, and all original shipping instructions, delivery
receipts, bills of lading, and other evidence of delivery, for any goods the
sale or disposition of which gave rise to such Receivables, and Borrower
warrants the genuineness of all of the foregoing. Borrower shall also furnish to
Coast an aged accounts receivable trial balance in such form and at such
intervals as Coast shall request. In addition, Borrower shall deliver to Coast
the originals of all instruments, chattel paper, security agreements, guarantees
and other documents and property evidencing or securing any Receivables, upon
receipt thereof and in the same form as received, with all necessary
endorsements, all of which shall be with recourse. Borrower shall also provide
Coast with copies of all credit memos as and when requested by Coast.

            4.4 Collection of Receivables. Borrower shall have the right to
collect all Receivables, unless and until an Event of Default has occurred.
Borrower shall hold all payments on, and proceeds of, Receivables in trust for
Coast, and Borrower shall deliver all such payments and proceeds to Coast within
one Business Day after receipt by Borrower, in their original form, duly
endorsed to Coast, to be applied to the Obligations in such order as Coast shall
determine. Coast may, in its discretion, require that all proceeds of Collateral
be deposited by Borrower into a lockbox account, or such other "blocked account"
as Coast may specify, pursuant to a blocked account agreement in such form as
Coast may specify. Coast or its designee may, at any time, notify Account
Debtors that Coast has been granted a security interest in the Receivables.

            4.5. Remittance of Proceeds. All proceeds arising from the
disposition of any Collateral shall be delivered to Coast within one Business
Day after receipt by Borrower, in their original form, duly endorsed to Coast,
to be applied to the Obligations in such order as Coast shall determine.
Borrower agrees that it will not commingle proceeds of Collateral with any of
Borrower's other funds or property, but will hold such proceeds separate and
apart from such other funds and property and in an express trust for Coast.
Nothing in this Section limits the restrictions on disposition of Collateral set
forth elsewhere in this Agreement.


                                      -3-
<PAGE>

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

            4.6 Disputes. Borrower shall notify Coast promptly of all material
disputes or claims relating to Receivables. Borrower shall not forgive
(completely or partially), compromise or settle any Receivable for less than
payment in full, or agree to do any of the foregoing, except that Borrower may
do so, provided that: (i) Borrower does so in good faith, in a commercially
reasonable manner, in the ordinary course of business, and in arm's length
transactions, which are reported to Coast on the regular reports provided to
Coast; (ii) no Default or Event of Default has occurred and is continuing; and
(iii) taking into account all such discounts settlements and forgiveness, the
total outstanding Loans will not exceed the Credit Limit. Coast may, at any time
after the occurrence of an Event of Default, settle or adjust disputes or claims
directly with Account Debtors for amounts and upon terms which Coast considers
advisable in its reasonable credit judgment and, in all cases, Coast shall
credit Borrower's Loan account with only the net amounts received by Coast in
payment of any Receivables.

            4.7 Returns. Provided no Event of Default has occurred and is
continuing, if any Account Debtor returns any Inventory to Borrower in the
ordinary course of its business, Borrower shall promptly determine the reason
for such return and promptly issue a credit memorandum to the Account Debtor in
the appropriate amount. In the event any attempted return occurs after the
occurrence of any Event of Default, Borrower shall (i) hold the returned
Inventory in trust for Coast, (ii) segregate all returned Inventory from all of
Borrower's other property, (iii) conspicuously label the returned Inventory as
subject to Coast's security interest, and (iv) immediately notify Coast of the
return of any Inventory, specifying the reason for such return, the location and
condition of the returned Inventory, and on Coast's request deliver such
returned Inventory to Coast.

            4.8 Verification. Coast may, from time to time, verify directly with
the respective Account Debtors the validity, amount and other matters relating
to the Receivables, by means of mail, telephone or otherwise, either in the name
of Borrower or Coast or such other name as Coast may choose.

            4.9 No Liability. Coast shall not under any circumstances be
responsible or liable for any shortage or discrepancy in, damage to, or loss or
destruction of, any goods, the sale or other disposition of which gives rise to
a Receivable, or for any error, act, omission, or delay of any kind occurring in
the settlement, failure to settle, collection or failure to collect any
Receivable, or for settling any Receivable in good faith for less than the full
amount thereof, nor shall Coast be deemed to be responsible for any of
Borrower's obligations under any contract or agreement giving rise to a
Receivable. Nothing herein shall, however, relieve Coast from liability for its
own gross negligence or willful misconduct.

            4.10  See Schedule.

            5.  ADDITIONAL DUTIES OF THE BORROWER.

            5.1 Financial and Other Covenants. Borrower shall at all times
comply with the financial and other covenants set forth in the Schedule.

            5.2 Insurance. Borrower shall, at all times insure all of the
tangible personal property Collateral and carry such other business insurance,
with insurers reasonably acceptable to Coast, in such form and amounts as Coast
may reasonably require, and Borrower shall provide evidence of such insurance to
Coast, so that Coast is satisfied that such insurance is, at all times, in full
force and effect. All liability insurance policies of Borrower shall name Coast
as an additional insured, and all property casualty and related insurance
policies of Borrower shall name Coast as a loss payee thereon and Borrower shall
cause a lenders loss payee endorsement in form reasonably acceptable to Coast.
Upon receipt of the proceeds of any such insurance, Coast shall apply such
proceeds in reduction of the Obligations as Coast shall determine in its sole
discretion, except that, provided no Default or Event of Default has occurred
and is continuing, Coast shall release to Borrower insurance proceeds with
respect to Equipment totaling less than $25,000.00, which shall be utilized by
Borrower for the replacement of the Equipment with respect to which the
insurance proceeds were paid. Coast may require reasonable assurance that the
insurance proceeds so released will be so used. If Borrower fails to provide or
pay for any insurance, Coast may, but is not obligated to, obtain the same at
Borrower's expense. Borrower shall promptly deliver to Coast copies of all
reports made to insurance companies.

            5.3 Reports. Borrower, at its expense, shall provide Coast with the
written reports set forth in the Schedule, and such other written reports with
respect to Borrower (including budgets, sales projections, operating plans and
other financial documentation), as Coast shall from time to time reasonably
specify.

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

            5.4 Access to Collateral, Books and Records. At reasonable times,
and on one Business Day's notice, Coast, or its agents, shall have the right to
inspect, audit and copy Borrower's books and records and the Collateral (the
"Audits"). Coast shall take reasonable steps to keep confidential all
confidential information obtained in any Audit, but Coast shall have the right
to disclose any such information to its auditors, regulatory agencies, and
attorneys, and pursuant to any subpoena or other legal process. The Audits shall
be at Borrower's expense. The charge for the Audits shall be $550.00 per person
per day (or such higher amount as shall represent Coast's then current standard
charge for the same) not to exceed $3,500.00 per quarter, plus reasonable out of
pocket expenses. Borrower will not enter into any agreement with any accounting
firm, service bureau or third party to store Borrower's books or records at any
location other than Borrower's Address, without first notifying Coast of the
same and obtaining the written agreement from such accounting firm, service
bureau or other third party to give Coast the same rights with respect to access
to books and records and related rights as Coast has under this Loan Agreement.

            5.5 Negative Covenants. Borrower shall not, without Coast's prior
written consent, do any of the following:

      (i) merge or consolidate with another corporation or entity, except in a
transaction in which (A) the shareholders of the Borrower hold at least 50% of
the common stock and all other capital stock of the surviving corporation
immediately after such merger or consolidation, and (B) the Borrower is the
surviving corporation;

      (ii) acquire any assets, except (A) in the ordinary course of business, or
(B) in a transaction or a series of transactions not involving the payment of an
aggregate amount in excess of $100,000.00.

      (iii) enter into any other transaction outside the ordinary course of
business;

      (iv) sell or transfer any Collateral, except for the sale of finished
Inventory in the ordinary course of Borrower's business, and except for the sale
of obsolete or unneeded Equipment in the ordinary course of business;

      (v) store any Inventory or other Collateral with any warehouseman or other
third party;

      (vi) sell any Inventory on a sale-or-return, guaranteed sale, consignment,
or other contingent basis; if Inventory is sold on such basis, such sales shall
be reported to Coast and the receivables therefrom shall not be deemed "Eligible
Receivables". Collection of such Inventory and Receivables shall, when
collected, be applied to the Obligations;

      (vii) make any loans of any money or other assets, except (A) advances to
customers or suppliers in the ordinary course of business, (B) travel advances,
employee relocation loans and other employee loans and advances in the ordinary
course of business, and (C) loans to employees, officers and directors for the
purpose of purchasing equity securities of the Borrower in excess of

would have a material, adverse effect on Borrower or on the prospect of
repayment of the Obligations;

      (ix) guarantee or otherwise become liable with respect to the obligations
of another party or entity;

      (x) pay or declare any dividends on Borrower's stock (except for dividends

owned by employees, directors and consultants of Borrower pursuant to terms of
employment, consulting or other stock restriction agreements at such time as any
such employee, director or consultant terminates his or her affiliation with the
Borrower, for an aggregate purchase price not to exceed $100,000 in any fiscal
year;

      (xii) make any change in Borrower's capital structure which would have a
material adverse effect on Borrower or on the prospect of repayment of the
Obligations; or

      (xiii) dissolve or elect to dissolve.

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

Transactions permitted by the foregoing provisions of this Section are only
permitted if no Default or Event of Default would occur as a result of such
transaction.

            5.6 Litigation Cooperation. Should any third-party suit or
proceeding be instituted by or against Coast with respect to any Collateral or
relating to Borrower, Borrower shall, without expense to Coast, make available
Borrower and its officers, employees and agents and Borrower's books and
records, to the extent that Coast may deem them reasonably necessary in order to
prosecute or defend any such suit or proceeding.

            5.7 Indemnity. Borrower hereby agrees to indemnify Coast and hold
Coast harmless from and against any and all claims, debts, liabilities, demands,
obligations, actions, causes of action, penalties, reasonable costs and expenses
(including reasonable attorneys' fees), of every nature, character and
description, which Coast may sustain or incur based upon or arising out of any
of the Obligations, any actual or alleged failure to collect and pay over any
withholding or other tax relating to Borrower or its employees, any relationship
or agreement between Coast and Borrower, any actual or alleged failure of Coast
to comply with any writ of attachment or other legal process relating to
Borrower or any of its property, or any other matter, cause or thing whatsoever
occurred, done, omitted or suffered to be done by Coast relating to Borrower or
the Obligations (except any such amounts sustained or incurred as the result of
the gross negligence or willful misconduct of Coast). Notwithstanding any
provision in this Agreement to the contrary, the indemnity agreement set forth
in this Section shall survive any termination of this Agreement and shall for
all purposes continue in full force and effect.

            5.8 Further Assurances. Borrower agrees, at its expense, on request
by Coast, to execute all documents and take all actions, as Coast, may deem
reasonably necessary or useful in order to perfect and maintain Coast's
perfected security interest in the Collateral, and in order to fully consummate
the transactions contemplated by this Agreement.

            6. TERM.

            6.1 Maturity Date. This Agreement shall continue in effect until the
maturity date set forth on the Schedule (the "Maturity Date"); provided that the
Maturity date shall automatically be extended, and this Agreement shall
automatically and continuously renew, for successive additional terms of one
year each, unless one party gives written notice to the other, not less than
sixty days prior to the next Maturity Date, that such party elects to terminate
this Agreement effective on the next Maturity Date.

            6.2 Early Termination. This Agreement may be terminated prior to the
Maturity Date as follows: (i) by Borrower, effective three Business Days after
written notice of termination is given to Coast; or (ii) by Coast at any time
after the occurrence of an Event of Default, effective immediately. If this
Agreement is terminated by Borrower under this Section 6.2, Borrower shall pay
to Coast a termination fee (the "Early Termination Fee") in the amount shown on
the Schedule. The Early Termination Fee shall be due and payable on the
effective date of termination.

            6.3 Payment of Obligations. On the Maturity Date or on any earlier
effective date of termination, Borrower shall pay and perform in full all
Obligations, whether evidenced by installment notes or otherwise, and whether or
not all or any part of such Obligations are otherwise then due and payable.
Without limiting the generality of the foregoing, if on the Maturity Date, or on
any earlier effective date of termination, there are any outstanding Letters of
Credit issued by Coast or issued by another institution based upon an
application, guarantee, indemnity or similar agreement on the part of Coast,
then on such date Borrower shall provide to Coast cash collateral in an amount
equal to the face amount of all such Letters of Credit plus all interest, fees
and cost due or to become due in connection therewith, to secure all of the
Obligations relating to said Letters of Credit, pursuant to Coast's then
standard form cash pledge agreement. Notwithstanding any termination of this
Agreement, all of Coast's security interests in all of the Collateral and all of
the terms and provisions of this Agreement shall continue in full force and
effect until all Obligations have been paid and performed in full; provided
that, without limiting the fact that Loans are subject to the discretion of
Coast, Coast may, in its sole discretion, refuse to make any further Loans after
termination. No termination shall in any way affect or impair any right or
remedy of Coast, nor shall any such termination relieve Borrower of any
Obligation to Coast, until all of the Obligations have been paid and performed
in full. Upon payment and performance in full of all the Obligations and
termination of this Agreement, Coast shall promptly deliver to Borrower
termination statements, requests for reconveyances and such other documents as
may be required to fully terminate Coast's security interests.

            7. EVENTS OF DEFAULT AND REMEDIES.

or (j) Dissolution, termination of existence, insolvency or business failure of

commencement of any proceeding against Borrower or any guarantor of any of the
Obligations under any reorganization, bankruptcy, insolvency, arrangement,

jurisdiction, now or in the future in effect, which is not cured by the
dismissal thereof within 30 days after the date commenced; or (l) revocation or
termination of, or limitation or denial of liability upon, any guaranty of the
Obligations or any attempt to do any of the foregoing, or commencement of
proceedings by any guarantor of any of the Obligations under any bankruptcy or
insolvency law; or (m) revocation or termination of, or limitation or denial of
liability upon, any pledge of any certificate of deposit, securities or other

proceedings by or against any such third party under any bankruptcy or
insolvency law; or (n) Borrower makes any payment on account of any indebtedness
or obligation which has been subordinated to the Obligations, other than as

beneficial ownership of an aggregate of more than 20% of the outstanding shares
of stock of Borrower, in one or more transactions, compared to the ownership of
outstanding shares of stock of Borrower in effect on the date hereof, without
the prior written consent of Coast; or (p) Borrower shall generally not pay its
debts as they become due, or Borrower shall conceal, remove or transfer any part
of its property, with intent to hinder, delay or defraud its creditors, or make
or suffer any transfer of any of its property which may be fraudulent under any

material adverse change in Borrower's business or financial condition. Coast may
cease making any Loans hereunder during any of the above cure periods, and
thereafter if an Event of Default has occurred.

            7.2 Remedies. Upon the occurrence, and during the continuance, of
any Event of Default, Coast, at its option, and without notice or demand of any
kind (all of which are hereby expressly waived by Borrower), may do any one or
more of the following: (a) Cease making Loans or otherwise extending credit to
Borrower under this Agreement or any other document or agreement; (b) Accelerate
and declare all or any part of the Obligations to be immediately due, payable,
and performable, notwithstanding any deferred or installment payments allowed by
any instrument evidencing or relating to any Obligation; (c) Take possession of
any or all of the Collateral wherever it may be found, and for that purpose
Borrower hereby authorizes Coast without judicial process to enter onto any of
Borrower's premises without interference to search for, take possession of,
keep, store, or remove any of the Collateral, and remain on the premises or
cause a custodian to remain on the premises in exclusive control thereof,
without charge for so long as Coast deems it reasonably necessary in order to
complete the enforcement of its rights under this Agreement or any other
agreement; provided, however, that should Coast seek to take possession of any
of the Collateral by Court process, Borrower hereby irrevocably waives: (i) any
bond and any surety or security relating thereto required by any statute, court
rule or otherwise as an incident to such possession; (ii) any demand for
possession prior to the commencement of any suit or action to recover possession
thereof; and (iii) any requirement that Coast retain possession of, and not
dispose of, any such Collateral until after trial or final judgment; (d) Require
Borrower to assemble any or all of the Collateral and make it available to Coast
at places designated by Coast which


                                      -7-
<PAGE>

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

are reasonably convenient to Coast and Borrower, and to remove the Collateral to
such locations as Coast may deem advisable; (e) Complete the processing,
manufacturing or repair of any Collateral prior to a disposition thereof and,
for such purpose and for the purpose of removal, Coast shall have the right to
use Borrower's premises, vehicles, hoists, lifts, cranes, equipment and all
other property without charge; (f) Sell, lease or otherwise dispose of any of
the Collateral, in its condition at the time Coast obtains possession of it or
after further manufacturing, processing or repair, at one or more public and/or
private sales, in lots or in bulk, for cash, exchange or other property, or on
credit, and to adjourn any such sale from time to time without notice other than
oral announcement at the time scheduled for sale. Coast shall have the right to
conduct such disposition on Borrower's premises without charge, for such time or
times as Coast deems reasonable, or on Coast's premises, or elsewhere and the
Collateral need not be located at the place of disposition. Coast may directly
or through any affiliated company purchase or lease any Collateral at any such
public disposition, and if permissible under applicable law, at any private
disposition. Any sale or other disposition of Collateral shall not relieve
Borrower of any liability Borrower may have if any Collateral is defective as to
title or physical condition or otherwise at the time of sale; (g) Demand payment
of, and collect any Receivables and General Intangibles comprising Collateral
and, in connection therewith, Borrower irrevocably authorizes Coast to endorse
or sign Borrower's name on all collections, receipts, instruments and other
documents, to take possession of and open mail addressed to Borrower and remove
therefrom payments made with respect to any item of the Collateral or proceeds
thereof, and, in Coast's sole discretion, to grant extensions of time to pay,
compromise claims and settle Receivables and the like for less than face value;
(h) Offset against any sums in any of Borrower's general, special or other
Deposit Accounts with Coast; and (i) Demand and receive possession of any of
Borrower's federal and state income tax returns and the books and records
utilized in the preparation thereof or referring thereto. All reasonable
attorneys' fees, expenses, costs, liabilities and obligations incurred by Coast
with respect to the foregoing shall be due from the Borrower to Coast on demand.
Coast may charge the same to Borrower's loan account, and the same shall
thereafter bear interest at the same rate as is applicable to the Receivable
Loans. Without limiting any of Coast's rights and remedies, from and after the
occurrence of any Event of Default, the interest rate applicable to the
Obligations shall be increased by an additional three percent per annum.

            7.3 Standards for Determining Commercial Reasonableness. Borrower
and Coast agree that a sale or other disposition (collectively, "sale") of any
Collateral which complies with the following standards will conclusively be
deemed to be commercially reasonable: (i) Notice of the sale is given to
Borrower at least seven days prior to the sale, and, in the case of a public
sale, notice of the sale is published at least seven days before the sale in a
newspaper of general circulation in the county where the sale is to be
conducted; (ii) Notice of the sale describes the collateral in general,
non-specific terms; (iii) The sale is conducted at a place designated by Coast,
with or without the Collateral being present; (iv) The sale commences at any
time between 8:00 a.m. and 6:00 p.m (the time being that of the location of the
sale); (v) Payment of the purchase price in cash or by cashier's check or wire
transfer is required; (vi) With respect to any sale of any of the Collateral,
Coast may (but is not obligated to) direct any prospective purchaser to
ascertain directly from Borrower any and all information concerning the same.
Coast shall be free to employ other methods of noticing and selling the
Collateral, in its discretion, if they are commercially reasonable.

            7.4 Power of Attorney. Upon the occurrence, and during the
continuance, of any Event of Default, without limiting Coast's other rights and
remedies, Borrower grants to Coast an irrevocable power of attorney coupled with
an interest, authorizing and permitting Coast (acting through any of its
employees, attorneys or agents) at any time, at its option, but without
obligation, with or without notice to Borrower, and at Borrower's expense, to do
any or all of the following, in Borrower's name or otherwise, but Coast agrees
to exercise the following powers in a commercially reasonable manner: (a)
Execute on behalf of Borrower any documents that Coast may, in its sole
discretion, deem advisable in order to perfect and maintain Coast's security
interest in the Collateral, or in order to exercise a right of Borrower or
Coast, or in order to fully consummate all the transactions contemplated under
this Agreement, and all other present and future agreements; (b) Execute on
behalf of Borrower any document exercising, transferring or assigning any option
to purchase, sell or otherwise dispose of or to lease (as lessor or lessee) any
real or personal property which is part of Coast's Collateral or in which Coast
has an interest; (c) Execute on behalf of Borrower, any invoices relating to any
Receivable, any draft against any Account Debtor and any notice to any Account
Debtor, any proof of claim in bankruptcy, any Notice of Lien, claim of
mechanic's, materialman's or other lien, or assignment or satisfaction of
mechanic's, materialman's or other lien; (d) Take control in any manner of any
cash or non-cash items of payment or proceeds of Collateral; endorse the name of
Borrower upon any instruments, or documents, evidence of payment or Collateral
that may come into Coast's possession; (e) Endorse all checks and other forms of
remittances received by Coast; (f) Pay, contest or settle any lien, charge,
encumbrance, security interest and adverse claim in or to any of the Collateral,
or any judgment based thereon, or otherwise take any action to terminate or
discharge the same; (g) Grant extensions of time to pay, compromise claims and
settle Receivables and General Intangibles


                                      -8-
<PAGE>

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

for less than face value and execute all releases and other documents in
connection therewith; (h) Pay any sums required on account of Borrower's taxes
or to secure the release of any liens therefor, or both; (i) Settle and adjust,
and give releases of, any insurance claim that relates to any of the Collateral
and obtain payment therefor; (j) Instruct any third party having custody or
control of any books or records belonging or relating to, Borrower to give Coast
the same rights of access and other rights with respect thereto as Coast has
under this Agreement; and (k) Take any action or pay any sum required of
Borrower pursuant to this Agreement and any other present or future agreements.
Any and all reasonable sums paid and any and all reasonable costs, expenses,
liabilities, obligations and attorneys' fees incurred by Coast with respect to
the foregoing shall be added to and become part of the Obligations, and shall be
payable on demand. Coast may charge the foregoing to Borrower's loan account and
the foregoing shall thereafter bear interest at the same rate applicable to the
Receivable Loans. In no event shall Coast's rights under the foregoing power of
attorney or any of Coast's other rights under this Agreement be deemed to
indicate that Coast is in control of the business, management or properties of
Borrower.

            7.5 Application of Proceeds. All proceeds realized as the result of
any sale of the Collateral shall be applied by Coast first to the reasonable
costs, expenses, liabilities, obligations and attorneys' fees incurred by Coast
in the exercise of its rights under this Agreement, second to the interest due
upon any of the Obligations, and third to the principal of the Obligations, in
such order as Coast shall determine in its sole discretion. Any surplus shall be
paid to Borrower or other persons legally entitled thereto; Borrower shall
remain liable to Coast for any deficiency. If, Coast, in its sole discretion,
directly or indirectly enters into a deferred payment or other credit
transaction with any purchaser at any sale of Collateral, Coast shall have the
option, exercisable at any time, in its sole discretion, of either reducing the
Obligations by the principal amount of purchase price or deferring the reduction
of the Obligations until the actual receipt by Coast of the cash therefor.

            7.6 Remedies Cumulative. In addition to the rights and remedies set
forth in this Agreement, Coast shall have all the other rights and remedies
accorded a secured party under the California Uniform Commercial Code and under
all other applicable laws, and under any other instrument or agreement now or in
the future entered into between Coast and Borrower, and all of such rights and
remedies are cumulative and none is exclusive. Exercise or partial exercise by
Coast of one or more of its rights or remedies shall not be deemed an election,
nor bar Coast from subsequent exercise or partial exercise of any other rights
or remedies. The failure or delay of Coast to exercise any rights or remedies
shall not operate as a waiver thereof, but all rights and remedies shall
continue in full force and effect until all of the Obligations have been fully
paid and performed.

be deemed applied by Coast on account of the Obligations three Business Days
after receipt by Coast of immediately available funds, and, for purposes of the

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

            9.4 Monthly Accountings. Coast shall provide Borrower monthly with
an account of advances, charges, expenses and payments made pursuant to this
Agreement. Such account shall be deemed correct, accurate and binding on
Borrower and an account stated (except for reverses and reapplications of
payments made and corrections of errors discovered by Coast), unless Borrower
notifies Coast in writing to the contrary within ninety days after each account
is rendered, describing the nature of any alleged errors or omissions.

            9.5 Notices. All notices to be given under this Agreement shall be
in writing and shall be given either personally or by reputable private delivery
service or by regular first-class mail, or certified mail return receipt
requested, addressed to Coast or Borrower at the addresses shown in the heading
to this Agreement, or at any other address designated in writing by one party to
the other party. Notices to Coast shall be directed to the Commercial Finance

            9.6 Severability. Should any provision of this Agreement be held by
any court of competent jurisdiction to be void or unenforceable, such defect
shall not affect the remainder of this Agreement, which shall continue in full
force and effect.

            9.7 Integration. This Agreement and such other written agreements,
documents and instruments as may be executed in connection herewith are the
final, entire and complete agreement between Borrower and Coast and supersede
all prior and contemporaneous negotiations and oral representations and
agreements, all of which are merged and integrated in this Agreement. There are
no oral understandings, representations or agreements between the parties which
are not set forth in this Agreement or in other written agreements signed by the
parties in connection herewith.

            9.8 Waivers. The failure of Coast at any time or times to require
Borrower to strictly comply with any of the provisions of this Agreement or any
other present or future agreement between Borrower and Coast shall not waive or
diminish any right of Coast later to demand and receive strict compliance
therewith. Any waiver of any default shall not waive or affect any other
default, whether prior or subsequent, and whether or not similar. None of the
provisions of this Agreement or any other agreement now or in the future
executed by Borrower and delivered to Coast shall be deemed to have been waived
by any act or knowledge of Coast or its agents or employees, but only by a
specific written waiver signed by an authorized officer of Coast and delivered
to Borrower. Borrower waives demand, protest, notice of protest and notice of
default or dishonor, notice of payment and nonpayment, release, compromise,
settlement, extension or renewal of any commercial paper, instrument, account,
General Intangible, document or guaranty at any time held by Coast on which
Borrower is or may in any way be liable, and notice of any action taken by
Coast, unless expressly required by this Agreement.

            9.9 No Liability for Ordinary Negligence. Neither Coast, nor any of
its directors, officers, employees, agents, attorneys or any other Person
affiliated with or representing Coast shall be liable for any claims, demands,
losses or damages, of any kind whatsoever, made, claimed, incurred or suffered
by Borrower or any other party through the ordinary negligence of Coast, or any
of its directors, officers, employees, agents, attorneys or any other Person
affiliated with or representing Coast, but nothing herein shall relieve Coast
from liability for its own gross negligence or willful misconduct.

            9.10 Amendment. The terms and provisions of this Agreement may not
be waived or amended, except in a writing executed by Borrower and a duly
authorized officer of Coast.

            9.11 Time of Essence. Time is of the essence in the performance by
Borrower of each and every obligation under this Agreement.

            9.12 Attorneys Fees, Costs and Charges. Borrower shall reimburse
Coast for all reasonable attorneys' fees and all filing, recording, search,
title insurance, appraisal, audit, and other reasonable costs incurred by Coast,
pursuant to, or in connection with, or relating to this Agreement (whether or
not a lawsuit is filed), including, but not limited to, any reasonable
attorneys' fees and costs Coast incurs in order to do the following: prepare and
negotiate this Agreement and the documents relating to this Agreement; obtain
legal advice in connection with this Agreement or Borrower; enforce, or seek to
enforce, any of its rights; prosecute actions against, or defend actions by,

any probate claim, bankruptcy claim, third-party claim, or other claim; examine,
audit, copy, and inspect any of the Collateral or any of Borrower's books and
records; protect, obtain possession of, lease, dispose of, or otherwise enforce
Coast's security interest in, the Collateral; and otherwise represent Coast in
any litigation relating to Borrower. If either Coast or Borrower files any
lawsuit against the other predicated on a breach of this Agreement, the
prevailing party in such action shall be entitled to recover its reasonable
costs and attorneys' fees, including (but not limited to) reasonable attorneys'
fees and costs incurred in the enforcement of, execution upon or defense of any
order, decree, award or judgment. Borrower shall also pay Coast's standard
charges for returned checks and for wire transfers, in effect from time to time.
All attorneys' fees, costs and charges to which Coast may be entitled pursuant
to this Paragraph may be charged by Coast to Borrower's loan account and shall
thereafter bear interest at the same rate as the Receivable Loans.

            9.13 Benefit of Agreement. The provisions of this Agreement shall be
binding upon and inure to the benefit of the respective successors, assigns,
heirs, beneficiaries and representatives of Borrower and Coast; provided,
however, that Borrower may not assign or transfer any of its rights under this
Agreement without the prior written consent of Coast, and any prohibited
assignment shall be void. No consent by Coast to any assignment shall release
Borrower from its liability for the Obligations.

            9.14 Publicity. Subject to Borrower's prior written consent, Coast
is hereby authorized, at its expense, to issue appropriate press releases and to
cause a tombstone to be published announcing the consummation of this
transaction and the aggregate amount thereof.

            9.15 Joint and Several Liability. If Borrower consists of more than
one Person, their liability shall be joint and several, and the compromise of
any claim with, or the release of, any Borrower shall not constitute a
compromise with, or a release of, any other Borrower.

            9.16 Limitation of Actions. Any claim or cause of action by Borrower
against Coast, its directors, officers, employees, agents, accountants or
attorneys, based upon, arising from, or relating to this Loan Agreement, or any
other present or future document or agreement, or any other transaction
contemplated hereby or thereby or relating hereto or thereto, or any other
matter, cause or thing whatsoever, occurred, done, omitted or suffered to be
done by Coast, its directors, officers, employees, agents, accountants or
attorneys, shall be barred unless asserted by Borrower by the commencement of an
action or proceeding in a court of competent jurisdiction by the filing of a
complaint within one year after the first act, occurrence or omission upon which
such claim or cause of action, or any part thereof, is based, and the service of
a summons and complaint on an officer of Coast, or on any other person
authorized to accept service on behalf of Coast, within thirty (30) days
thereafter. Borrower agrees that such one-year period is a reasonable and
sufficient time for Borrower to investigate and act upon any such claim or cause
of action. The one-year period provided herein shall not be waived, tolled, or
extended except by the written consent of Coast in its sole discretion. This
provision shall survive any termination of this Loan Agreement or any other
present or future agreement.

            9.17 Paragraph Headings; Construction. Paragraph headings are only
used in this Agreement for convenience. Borrower and Coast acknowledge that the
headings may not describe completely the subject matter of the applicable
paragraph, and the headings shall not be used in any manner to construe, limit,
define or interpret any term or provision of this Agreement. The term
"including", whenever used in this Agreement, shall mean "including (but not
limited to)". This Agreement has been fully reviewed and negotiated between the
parties and no uncertainty or ambiguity in any term or provision of this
Agreement shall be construed strictly against Coast or Borrower under any rule
of construction or otherwise.

            Address:          2800 28th Street, Suite 100

            Borrower:         Cray Communications, Inc., a Delaware corporation

            Address:          9020 Junction Drive

                              Annapolis Junction, MD 20791

            Date:             September 27, 1996

            This Continuing Guaranty is executed by the above-named guarantor
("Guarantor"), as of the above date, in favor of COAST BUSINESS CREDIT, a
division of Southern Pacific Thrift & Loan Association ("Coast"), a California
corporation, with offices at 12121 Wilshire Boulevard, Suite 1111, Los Angeles,
California 90025, with respect to the Indebtedness of Cray Communications, Inc.,
a Delaware corporation ("Borrower").

            1. Continuing Guaranty. Guarantor hereby unconditionally guarantees
and promises to pay on demand to Coast, at the address indicated above, or at
such other address as Coast may direct, in lawful money of the United States,
and to perform for the benefit of Coast, all Indebtedness of Borrower now or
hereafter owing to or held by Coast. As used herein, the term "Indebtedness" is
used in its most comprehensive sense and shall mean and include without
limitation: (a) any and all debts, duties, obligations, liabilities,
representations, warranties and guaranties of Borrower or any one or more of
them, heretofore, now, or hereafter made, incurred, or created, whether directly
to Coast or acquired by Coast by assignment or otherwise, or held by Coast on
behalf of others, however arising, whether voluntary or involuntary, due or not
due, absolute or contingent, liquidated or unliquidated, certain or uncertain,
determined or undetermined, monetary or nonmonetary, written or oral, and
whether Borrower may be liable individually or jointly with others, and
regardless of whether recovery thereon may be or hereafter become barred by any
statute of limitations, discharged or uncollectible in any bankruptcy,
insolvency or other proceeding, or otherwise unenforceable; and (b) any and all
amendments, modifications, renewals and extensions of any or all of the
foregoing, including without limitation amendments, modifications, renewals and
extensions which are evidenced by any new or additional instrument, document or
agreement; and (c) any and all attorneys' fees, court costs, and collection
charges incurred in endeavoring to collect or enforce any of the foregoing
against Borrower, Guarantor, or any other person liable thereon (whether or not
suit be brought) and any other expenses of, for or incidental to collection
thereof. As used herein, the term "Borrower" shall include any successor to the
business and assets of

                                                           Coast Business Credit
               Continuing Guaranty
            --------------------------------------------------------------------

Borrower, and shall also include Borrower in its capacity as a debtor or debtor
in possession under the federal Bankruptcy Code, and any trustee, custodian or
receiver for Borrower or any of its assets, should Borrower hereafter become the
subject of any bankruptcy or insolvency proceeding, voluntary or involuntary;
and all indebtedness, liabilities and obligations incurred by any such person
shall be included in the Indebtedness guaranteed hereby. This Guaranty is given
in consideration for credit and other financial accommodations which may, from
time to time, be given by Coast to Borrower in Coast's sole discretion, but
Guarantor acknowledges and agrees that acceptance by Coast of this Guaranty
shall not constitute a commitment of any kind by Coast to extend such credit or
other financial accommodation to Borrower or to permit Borrower to incur
Indebtedness to Coast. All sums due under this Guaranty shall bear interest from
the date due until the date paid at the highest rate charged with respect to any
of the Indebtedness.

            2. Waivers. Guarantor hereby waives: (a) presentment for payment,
notice of dishonor, protest, and notice thereof as to any instrument, and all
other notices and demands to which Guarantor might be entitled, including
without limitation notice of all of the following: the acceptance hereof; the
creation, existence, or acquisition of any Indebtedness; the amount of the
Indebtedness from time to time outstanding; disposition of any property which
secures any or all of the Indebtedness or which secures the obligations of any
other guarantor of any or all of the Indebtedness; any adverse change in
Borrower's financial position; any other fact which might increase Guarantor's
risk; any default, partial payment or non-payment of all or any part of the
Indebtedness; any and all agreements and arrangements between Coast and Borrower
and any changes, modifications, or extensions thereof, and any revocation,
modification or release of any guaranty of any or all of the Indebtedness by any
person (including without limitation any other person signing this Guaranty);
(b) any right to require Coast to institute suit against, or to exhaust its
rights and remedies against, Borrower or any other person, or to proceed against
any property of any kind which secures all or any part of the Indebtedness, or
to exercise any right of offset or other right with respect to any reserves,
credits or deposit accounts held by or maintained with Coast or any indebtedness
of Coast to Borrower, or to exercise any other right or power, or pursue any
other remedy Coast may have; (c) any defense arising by reason of any disability
or other defense of Borrower or any other guarantor or any endorser, co-maker or
other person, or by reason of the cessation from any cause whatsoever of any
liability of Borrower or any other guarantor or any endorser, co-maker or other
person, with respect to all or any part of the Indebtedness, or by reason of any
act or omission of Coast or others which directly or indirectly results in the
discharge or release of Borrower or any other guarantor or any other person or
any Indebtedness or any security therefor, whether by operation of law or
otherwise; (d) any defense arising by reason of any failure of Coast to obtain,
perfect, maintain or keep in force any security interest in, or lien or
encumbrance upon, any property of Borrower or any other person; (e) any defense
based upon any failure of Coast to give Guarantor notice of any sale or other
disposition of any property securing any or all of the Indebtedness, or any
defects in any such notice that may be given, or any failure of Coast to comply
with any provision of applicable law in enforcing any security interest in or
lien upon any property securing any or all of the Indebtedness including, but
not limited to, any failure by Coast to dispose of any property securing any or
all of the Indebtedness in a commercially reasonable manner; (f) any defense
based upon or arising out of any bankruptcy, insolvency, reorganization,
arrangement, readjustment of debt, liquidation or dissolution proceeding
commenced by or against Borrower or any other guarantor or any endorser,
co-maker or other person, including without limitation any discharge of, or bar
against collecting, any of the Indebtedness (including without limitation any
interest thereon), in or as a result of any such proceeding; and (g) the benefit
of any and all statutes of limitation with respect to any action based upon,
arising out of or related to this Guaranty. Until all of the Indebtedness has
been paid, performed, and discharged in full, nothing shall discharge or satisfy
the liability of Guarantor hereunder except the full performance and payment of
all of the Indebtedness. If any claim is ever made upon Coast for repayment or
recovery of any amount or amounts received by Coast in payment of or on account
of any of the Indebtedness, because of any claim that any such payment
constituted a preferential transfer or fraudulent conveyance, or for any other
reason whatsoever, and Coast repays all or part of said amount by reason of any
judgment, decree or order of any court or administrative body having
jurisdiction over Coast or any of its property, or by reason of any settlement
or compromise of any such claim effected by Coast with any such claimant
(including without limitation the Borrower), then and in any such event,
Guarantor agrees that any such judgment, decree, order, settlement and
compromise shall be binding upon Guarantor, notwithstanding any revocation or
release of this Guaranty or the cancellation of any note or other instrument
evidencing any of the Indebtedness, or any

               Continuing Guaranty
            --------------------------------------------------------------------

release of any of the Indebtedness, and the Guarantor shall be and remain liable
to Coast under this Guaranty for the amount so repaid or recovered, to the same
extent as if such amount had never originally been received by Coast, and the
provisions of this sentence shall survive, and continue in effect,
notwithstanding any revocation or release of this Guaranty. Until all of the
Indebtedness has been irrevocably paid and performed in full, Guarantor hereby
expressly and unconditionally waives all rights of subrogation, reimbursement
and indemnity of every kind against Borrower, and all rights of recourse to any
assets or property of Borrower, and all rights to any collateral or security
held for the payment and performance of any Indebtedness, including (but not
limited to) any of the foregoing rights which Guarantor may have under any
present or future document or agreement with any Borrower or other person, and
including (but not limited to) any of the foregoing rights which Guarantor may
have under any equitable doctrine of subrogation, implied contract, or unjust
enrichment, or any other equitable or legal doctrine. Neither Coast, nor any of
its directors, officers, employees, agents, attorneys or any other person
affiliated with or representing Coast shall be liable for any claims, demands,
losses or damages, of any kind whatsoever, made, claimed, incurred or suffered
by Guarantor or any other party through the ordinary negligence of Coast, or any
of its directors, officers, employees, agents, attorneys or any other person
affiliated with or representing Coast.

            3. Consents. Guarantor hereby consents and agrees that, without
notice to or by Guarantor and without affecting or impairing in any way the
obligations or liability of Guarantor hereunder, Coast may, from time to time
before or after revocation of this Guaranty, do any one or more of the following
in Coast's sole and absolute discretion: (a) accelerate, accept partial payments
of, compromise or settle, renew, extend the time for the payment, discharge, or
performance of, refuse to enforce, and release all or any parties to, any or all
of the Indebtedness; (b) grant any other indulgence to Borrower or any other
person in respect of any or all of the Indebtedness or any other matter; (c)
accept, release, waive, surrender, enforce, exchange, modify, impair, or extend
the time for the performance, discharge, or payment of, any and all property of
any kind securing any or all of the Indebtedness or any guaranty of any or all
of the Indebtedness, or on which Coast at any time may have a lien, or refuse to
enforce its rights or make any compromise or settlement or agreement therefor in
respect of any or all of such property; (d) substitute or add, or take any
action or omit to take any action which results in the release of, any one or
more endorsers or guarantors of all or any part of the Indebtedness, including,
without limitation one or more parties to this Guaranty, regardless of any
destruction or impairment of any right of contribution or other right of
Guarantor; (e) amend, alter or change in any respect whatsoever any term or
provision relating to any or all of the Indebtedness, including the rate of
interest thereon; (f) apply any sums received from Borrower, any other
guarantor, endorser, or co-signer, or from the disposition of any collateral or
security, to any indebtedness whatsoever owing from such person or secured by
such collateral or security, in such manner and order as Coast determines in its
sole discretion, and regardless of whether such indebtedness is part of the
Indebtedness, is secured, or is due and payable; (g) apply any sums received
from Guarantor or from the disposition of any collateral or security securing
the obligations of Guarantor, to any of the Indebtedness in such manner and
order as Coast determines in its sole discretion, regardless of whether or not
such Indebtedness is secured or is due and payable. Guarantor consents and
agrees that Coast shall be under no obligation to marshal any assets in favor of
Guarantor, or against or in payment of any or all of the Indebtedness. Guarantor
further consents and agrees that Coast shall have no duties or responsibilities
whatsoever with respect to any property securing any or all of the Indebtedness.
Without limiting the generality of the foregoing, Coast shall have no obligation
to monitor, verify, audit, examine, or obtain or maintain any insurance with
respect to, any property securing any or all of the Indebtedness.

            4. Account Stated. Coast's books and records showing the account
between it and the Borrower shall be admissible in evidence in any action or
proceeding as prima facie proof of the items therein set forth. Coast's monthly
statements rendered to the Borrower shall be binding upon the Guarantor (whether
or not the Guarantor receives copies thereof), and shall constitute an account
stated between Coast and the Borrower, unless Coast receives a written statement
of the Borrower's exceptions within 30 days after the statement was mailed to
the Borrower. The Guarantor assumes full responsibility for obtaining copies of
such monthly statements from the Borrower, if the Guarantor desires such copies.

            5. Exercise of Rights and Remedies; Foreclosure of Trust Deeds.

               Continuing Guaranty
            --------------------------------------------------------------------

consents and agrees that, without notice to or by Guarantor and without
affecting or impairing in any way the obligations or liability of Guarantor
hereunder, Coast may, from time to time, before or after revocation of this
Guaranty, exercise any right or remedy it may have with respect to any or all of
the Indebtedness or any property securing any or all of the Indebtedness or any
guaranty thereof, including without limitation judicial foreclosure, nonjudicial
foreclosure, exercise of a power of sale, and taking a deed, assignment or
transfer in lieu of foreclosure as to any such property, and Guarantor expressly
waives any defense based upon the exercise of any such right or remedy,
notwithstanding the effect thereof upon any of Guarantor's rights, including
without limitation, any destruction of Guarantor's right of subrogation against
Borrower and any destruction of Guarantor's right of contribution or other right
against any other guarantor of any or all of the Indebtedness or against any
other person, whether by operation of Sections 580a, 580d or 726 of the
California Code of Civil Procedure, or any comparable provisions of the laws of
any other jurisdiction, or any other statutes or rules of law now or hereafter
in effect, or otherwise. Without limiting the generality of the foregoing, (a)
Guarantor waives all rights and defenses arising out of an election of remedies
by Coast, even though that election of remedies, such as a nonjudicial
foreclosure with respect to security for any of the Indebtedness, has destroyed
the guarantor's rights of subrogation and reimbursement against the principal by
the operation of Section 580d of the Code of Civil Procedure or otherwise. (b)
Guarantor further waives all rights and defenses arising out of an election of
remedies by Coast, even though that election of remedies, such as a nonjudicial
foreclosure with respect to security for any of the Indebtedness, has destroyed
the guarantor's rights of subrogation, reimbursement and contribution against
any other guarantor of the guaranteed obligation, by the operation of Section
580d of the Code of Civil Procedure or otherwise. (c) Guarantor understands that
if Coast forecloses any present or future trust deed, which secures any or all
of the Indebtedness or which secures any other guaranty of any or all of the
Indebtedness, by nonjudicial foreclosure, Guarantor may, as a result, have a
complete defense to liability under this Guaranty, based on the legal doctrine
of estoppel and Sections 580a, 580d or 726 of the California Code of Civil
Procedure, and Guarantor hereby expressly waives all such defenses. (d)
Guarantor understands and agrees that, in the event Coast in its sole discretion
forecloses any trust deed now or hereafter securing any or all of the
Indebtedness, by nonjudicial foreclosure, Guarantor will remain liable to Coast
for any deficiency, even though Guarantor will lose his right of subrogation
against the Borrower, and even though Guarantor will be unable to recover from
the Borrower the amount of the deficiency for which Guarantor is liable, and
even though Guarantor may have retained his right of subrogation against
Borrower if Coast had foreclosed said trust deed by judicial foreclosure as
opposed to nonjudicial foreclosure, and even though absent the waivers set forth
herein Guarantor may have had a complete defense to any liability for any
deficiency hereunder. (e) Guarantor understands and agrees that, in the event
Coast in its sole discretion forecloses any trust deed now or hereafter securing
any other guaranty of any or all of the Indebtedness, by nonjudicial
foreclosure, Guarantor will remain liable to Coast for any deficiency, even
though Guarantor will lose his right of subrogation or contribution against the
other guarantor, and even though Guarantor will be unable to recover from the
other guarantor any part of the deficiency for which Guarantor is liable, and
even though Guarantor may have retained his right of subrogation or contribution
against the other guarantor if Coast had foreclosed said trust deed by judicial
foreclosure as opposed to nonjudicial foreclosure, and even though absent the
waivers set forth herein Guarantor may have had a complete defense to any
liability for any deficiency hereunder.

            6. Acceleration. Notwithstanding the terms of all or any part of the
Indebtedness, the obligations of the Guarantor hereunder to pay and perform all
of the Indebtedness shall, at the option of Coast, immediately become due and
payable, without notice, and without regard to the expressed maturity of any of
the Indebtedness, in the event: (a) any warranty, representation, statement,
report, or certificate made or delivered to Coast by Borrower or Guarantor, or
any of their respective officers, partners, employees, or agents, is incorrect,
false, untrue, or misleading when given in any material respect; or (b) Borrower
or Guarantor shall fail to pay or perform when due all or any part of the
Indebtedness; or (c) Guarantor shall fail to pay or perform within 5 days after
the same is due any indebtedness or obligation of Guarantor to Coast or to any
parent, subsidiary or corporate affiliate of Coast, whether under this Guaranty
or any other instrument, document, or agreement heretofore or hereafter entered
into; or (d) there occurs in Coast's judgment a material impairment of the
prospect of payment or performance of any or all of the Indebtedness; or (e) any
event shall occur which does result in the acceleration of the maturity of any
indebtedness of Borrower or Guarantor to others (regardless of any requirement
of notice, opportunity to cure or other condition prior to the exercise of any
right of acceleration); or (f) Borrower or Guarantor shall fail promptly to
perform or comply with any term or

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

condition of any agreement with any third party which does or may result in a
material adverse effect on the business of Borrower or Guarantor unless timely
cured or waived in writing by such third party; or (g) there shall be made or
exist any levy, assessment, attachment, seizure, lien, or encumbrance for any
cause or reason whatsoever upon all or any part of the property of Borrower or
Guarantor (unless discharged by payment, release or bond not more than ten days
after such event has occurred); or (h) there shall occur the dissolution,
termination of existence, insolvency, or business failure of Borrower or
Guarantor, or the appointment of a receiver, trustee or custodian for Borrower
or Guarantor or all or any part of the property of either of them, or the
assignment for the benefit of creditors by Borrower or Guarantor, or the
commencement of any proceeding by or against Borrower or Guarantor under any
reorganization, bankruptcy, insolvency, arrangement, readjustment of debt,
dissolution or liquidation law or statute of any jurisdiction, now or hereafter
in effect; or (i) Borrower or Guarantor shall be deceased or declared
incompetent by any court or a guardian or conservator shall be appointed for
either of them or for the property of either of them; or (j) Guarantor or
Borrower shall generally not pay their respective debts as they become due or
shall enter into any agreement (whether written or oral), or offer to enter into
any such agreement, with all or a significant number of its creditors regarding
any moratorium or other indulgence with respect to its debts or the
participation of such creditors or their representatives in the supervision,
management, or control of the business of either of them; or (k) Borrower or
Guarantor shall conceal, remove or permit to be concealed or removed any part of
its property, with intent to hinder, delay or defraud its creditors, or make or
suffer any transfer of any of its property which may be fraudulent under any
bankruptcy, fraudulent conveyance or similar law, or shall make any transfer of
its property to or for the benefit of any creditor at a time when other
creditors similarly situated have not been paid; or (l) the board of directors
or shareholders of Borrower or Guarantor shall adopt any resolution or plan for
its dissolution or the liquidation of all or substantially all of its assets; or
(m) Guarantor shall revoke this Guaranty or contest or deny liability under this
Guaranty. All of the foregoing are hereinafter referred to as "Events of
Default".

            7. Right to Attachment Remedy. Guarantor agrees that,
notwithstanding the existence of any property securing any or all of the
Indebtedness, Coast shall have all of the rights of an unsecured creditor of
Guarantor, including without limitation the right to obtain a temporary
protective order and writ of attachment against Guarantor with respect to any
sums due under this Guaranty. Guarantor further agrees that in the event any
property secures the obligations of Guarantor under this Guaranty, to the extent
that Coast, in its sole and absolute discretion, determines prior to the
disposition of such property that the amount to be realized by Coast therefrom
may be less than the indebtedness of the Guarantor under this Guaranty, Coast
shall have all the rights of an unsecured creditor against Guarantor, including
without limitation the right of Coast, prior to the disposition of said
property, to obtain a temporary protective order and writ of attachment against
Guarantor. Guarantor waives the benefit of Section 483.010(b) of the California
Code of Civil Procedure and of any and all other statutes and rules of law now
or hereafter in effect requiring Coast to first resort to or exhaust all such
collateral before seeking or obtaining any attachment remedy against Guarantor.
Coast shall have no liability to Guarantor as a result thereof, whether or not
the actual deficiency realized by Coast is less than the anticipated deficiency
on the basis of which Coast obtains a temporary protective order or writ of
attachment.

            8. Indemnity. Guarantor hereby agrees to indemnify Coast and hold
Coast harmless from and against any and all claims, debts, liabilities, demands,
obligations, actions, causes of action, penalties, costs and expenses (including
without limitation attorneys' fees), of every nature, character and description,
which Coast may sustain or incur based upon or arising out of any of the
Indebtedness, any actual or alleged failure to collect and pay over any
withholding or other tax relating to Borrower or its employees, any relationship
or agreement between Coast and Borrower, any actual or alleged failure of Coast
to comply with any writ of attachment or other legal process relating to
Borrower or any of its property, or any other matter, cause or thing whatsoever
occurred, done, omitted or suffered to be done by Coast relating in any way to
Borrower or the Indebtedness (except any such amounts sustained or incurred as
the result of the gross negligence or willful misconduct of Coast or any of its
directors, officers, employees, agents, attorneys, or any other person
affiliated with or representing Coast). Notwithstanding any provision in this
Guaranty to the contrary, the indemnity agreement set forth in this Section
shall survive any termination or revocation of this Guaranty and shall for all
purposes continue in full force and effect.

               Continuing Guaranty
            --------------------------------------------------------------------

            9. Subordination. Any and all debts, liabilities and obligations
owing from Borrower to Guarantor including any security for and guaranties of
any such obligations, whether now existing or hereafter arising, are hereby
subordinated in right of payment to the prior payment in full of all of the
Indebtedness. Except as permitted in that certain Subordination Agreement
between Guarantor and Coast dated as of September, 1996, and any written
amendments there, no payment in respect of any such subordinated obligations
shall at any time be made to or accepted by Guarantor if at the time of such
payment any Indebtedness is outstanding unless Coast, in its sole discretion,
agrees to such payment in writing. The agreement by Coast to a payment on
account of subordinated debt shall not constitute an agreement to the payment of
any other subordinated. If any Event of Default has occurred, all debts,
liabilities and obligations owing from Borrower to Guarantor shall be
subordinated, Borrower and any assignee, trustee in bankruptcy, receiver, or any
other person having custody or control over any or all of Borrower's property
are hereby authorized and directed to pay to Coast the entire unpaid balance of
the Indebtedness before making any payments whatsoever to Guarantor, whether as
a creditor, shareholder, or otherwise; and insofar as may be necessary for that
purpose, Guarantor hereby assigns and transfers to Coast all rights to any and
all debts, liabilities and obligations owing from Borrower to Guarantor,
including any security for and guaranties of any such obligations, whether now
existing or hereafter arising, including without limitation any payments,
dividends or distributions out of the business or assets of Borrower. Any
amounts received by Guarantor in violation of the foregoing provisions shall be
received and held as trustee for the benefit of Coast and shall forthwith be
paid over to Coast to be applied to the Indebtedness in such order and sequence
as Coast shall in its sole discretion determine, without limiting or affecting
any other right or remedy which Coast may have hereunder or otherwise and
without otherwise affecting the liability of Guarantor hereunder. Guarantor
hereby expressly waives any right to set-off or assert any counterclaim against
Borrower.

            10. Revocation. This is a Continuing Guaranty relating to all of the
Indebtedness, including Indebtedness arising under successive transactions which
from time to time continue the Indebtedness or renew it after it has been
satisfied. Guarantor waives all benefits of California Civil Code Section 2815,
and agrees that the obligations of Guarantor hereunder may not be terminated or
revoked in any manner except by giving written notice of revocation to Coast at
its address above by registered first-class U.S. mail, postage prepaid, return
receipt requested, and only as to new loans made by Coast to Borrower after
actual receipt of such written notice by Coast. No termination or revocation of
this Guaranty shall be effective until actual receipt of said written notice of
revocation by Coast. Notwithstanding such written notice of revocation or any
other act of Guarantor or any other event or circumstance, Guarantor agrees that
this Guaranty and all consents, waivers and other provisions hereof shall
continue in full force and effect as to any and all Indebtedness which is
outstanding on or before the day following actual receipt of said written notice
of revocation by Coast, and all extensions, renewals and modifications of said
Indebtedness (including without limitation amendments, extensions, renewals and
modifications which are evidenced by new or additional instruments, documents or
agreements executed before receipt of revocation, and all attorneys' fees, court
costs and collection charges, incurred before or after receipt of revocation, in
endeavoring to collect or enforce any of the foregoing against Borrower,
Guarantor or any other person liable thereon (whether or not suit be brought)
and any other expenses of, for or incidental to collection thereof.

            11. Independent Liability. Guarantor hereby agrees that one or more
successive or concurrent actions may be brought hereon against Guarantor, in the
same action in which Borrower may be sued or in separate actions, as often as
deemed advisable by Coast. The liability of Guarantor hereunder is exclusive and
independent of any other guaranty of any or all of the Indebtedness whether
executed by Guarantor or by any other guarantor (including without limitation
any other persons signing this Guaranty). The liability of Guarantor hereunder
shall not be affected, revoked, impaired, or reduced by any one or more of the
following: (a) the fact that the Indebtedness exceeds the maximum amount of
Guarantor's liability, if any, specified herein or elsewhere (and no agreement
specifying a maximum amount of Guarantor's liability shall be enforceable unless
set forth in a writing signed by Coast or set forth in this Guaranty); or (b)
any direction as to the application of payment by Borrower or by any other
party; or (c) any other continuing or restrictive guaranty or undertaking or any
limitation on the liability of any other guarantor (whether under this Guaranty
or under any other agreement); or (d) any payment on or reduction of any such
other guaranty or undertaking; or (e) any revocation, amendment, modification or
release of any such other guaranty or undertaking; or (f) any

               Continuing Guaranty
            --------------------------------------------------------------------

dissolution or termination of, or increase, decrease, or change in membership of
any Guarantor which is a partnership. Guarantor hereby expressly represents that
he was not induced to give this Guaranty by the fact that there are or may be
other guarantors either under this Guaranty or otherwise, and Guarantor agrees
that any release of any one or more of such other guarantors shall not release
Guarantor from his obligations hereunder either in full or to any lesser extent.
If Guarantor is a married person, Guarantor hereby expressly agrees that
recourse may be had against his or her separate property for all of his or her
obligations hereunder.

            12. Financial Condition of Borrower. Guarantor is fully aware of the
financial condition of Borrower and is executing and delivering this Guaranty at
Borrower's request and based solely upon his own independent investigation of
all matters pertinent hereto, and Guarantor is not relying in any manner upon
any representation or statement of Coast with respect thereto. Guarantor
represents and warrants that he is in a position to obtain, and Guarantor hereby
assumes full responsibility for obtaining, any additional information concerning
Borrower's financial condition and any other matter pertinent hereto as
Guarantor may desire, and Guarantor is not relying upon or expecting Coast to
furnish to him any information now or hereafter in Coast's possession concerning
the same or any other matter. By executing this Guaranty, Guarantor knowingly
accepts the full range of risks encompassed within a contract of continuing
guaranty, which risks Guarantor acknowledges include without limitation the
possibility that Borrower will incur additional Indebtedness for which Guarantor
will be liable hereunder after Borrower's financial condition or ability to pay
such Indebtedness has deteriorated and/or after bankruptcy or insolvency
proceedings have been commenced by or against Borrower. Guarantor shall have no
right to require Coast to obtain or disclose any information with respect to the
Indebtedness, the financial condition or character of Borrower, the existence of
any collateral or security for any or all of the Indebtedness, the filing by or
against Borrower of any bankruptcy or insolvency proceeding, the existence of
any other guaranties of all or any part of the Indebtedness, any action or
non-action on the part of Coast, Borrower, or any other person, or any other
matter, fact, or occurrence.

            13. Reports and Financial Statements of Guarantor. Guarantor shall,
at its sole cost and expense, at any time and from time to time, prepare or
cause to be prepared, and provide to Coast upon Coast's request (i) such
financial statements and reports concerning Guarantor for such periods of time
as Coast may designate, (ii) any other information concerning Guarantor's
business, financial condition or affairs as Coast may request, and (iii) copies
of any and all foreign, federal, state and local tax returns and reports of or
relating to Guarantor as Coast may from time to time request. Guarantor hereby
intentionally and knowingly waives any and all rights and privileges it may have
not to divulge or deliver said tax returns, reports and other information which
are requested by Coast hereunder or in any litigation in which Coast may be
involved relating directly or indirectly to Borrower or to Guarantor. Guarantor
further agrees immediately to give written notice to Coast of any adverse change
in Guarantor's financial condition and of any condition or event which
constitutes an Event of Default under this Guaranty. All reports and information
furnished to Coast hereunder shall be complete, accurate and correct in all
respects. Whenever requested, Guarantor shall further deliver to Coast a
certificate signed by Guarantor (and, if Guarantor is a partnership, by all
general partners of Guarantor, in their individual capacities, and, if Guarantor
is a corporation, by the president and secretary of Guarantor, in their
individual capacities) warranting and representing that all reports, financial
statements and other documents and information delivered or caused to be
delivered to Coast under this Guaranty, are complete, correct and thoroughly and
accurately present the financial condition of Guarantor, and that there exists
on the date of delivery of said certificate to Coast no condition or event which
constitutes an Event of Default under this Guaranty.

            14. Representations and Warranties. Guarantor hereby represents and
warrants that (i) it is in Guarantor's direct interest to assist Borrower in
procuring credit, because Borrower is an affiliate of Guarantor, furnishes goods
or services to Guarantor, purchases or acquires goods or services from
Guarantor, and/or otherwise has a direct or indirect corporate or business
relationship with Guarantor, (ii) this Guaranty has been duly and validly
authorized, executed and delivered and constitutes the valid and binding
obligation of Guarantor, enforceable in accordance with its terms, and (iii) the
execution and delivery of this Guaranty does not violate or constitute a default
under (with or without the giving of notice, the passage of time, or both) any
order, judgment, decree, instrument or agreement to which Guarantor is a party
or by which it or its assets are affected or bound.

                Continuing Guaranty
            --------------------------------------------------------------------

            15. Costs. Whether or not suit be instituted, Guarantor agrees to
reimburse Coast on demand for all reasonable attorneys' fees and all other
reasonable costs and expenses incurred by Coast in enforcing this Guaranty, or
arising out of or relating in any way to this Guaranty, or in enforcing any of
the Indebtedness against Borrower, Guarantor, or any other person, or in
connection with any property of any kind securing all or any part of the
Indebtedness. Without limiting the generality of the foregoing, and in addition
thereto, Guarantor shall reimburse Coast on demand for all reasonable attorneys'
fees and costs Coast incurs in any way relating to Guarantor, Borrower or the
Indebtedness, in order to: obtain legal advice; enforce or seek to enforce any
of its rights; commence, intervene in, respond to, or defend any action or
proceeding; file, prosecute or defend any claim or cause of action in any action
or proceeding (including without limitation any probate claim, bankruptcy claim,
third-party claim, secured creditor claim, reclamation complaint, and complaint
for relief from any stay under the Bankruptcy Code or otherwise); protect,
obtain possession of, sell, lease, dispose of or otherwise enforce any security
interest in or lien on any property of any kind securing any or all of the
Indebtedness; or represent Coast in any litigation with respect to Borrower's or
Guarantor's affairs. In the event either Coast or Guarantor files any lawsuit
against the other predicated on a breach of this Guaranty, the prevailing party
in such action shall be entitled to recover its attorneys' fees and costs of
suit from the non-prevailing party.

            16. Notices. Any notice which a party shall be required or shall
desire to give to the other hereunder (except for notice of revocation, which
shall be governed by Section 10 of this Guaranty) shall be given by personal
delivery or by telecopier or by depositing the same in the United States mail,
first class postage pre-paid, addressed to Coast at its address set forth in the
heading of this Guaranty and to Guarantor at his address set forth under his
signature hereon, and such notices shall be deemed duly given on the date of
personal delivery or one day after the date telecopied or 3 business days after
the date of mailing as aforesaid. Coast and Guarantor may change their address
for purposes of receiving notices hereunder by giving written notice thereof to
the other party in accordance herewith. Guarantor shall give Coast immediate
written notice of any change in his address.

            17. Claims. Guarantor agrees that any claim or cause of action by
Guarantor against Coast, or any of Coast's directors, officers, employees,
agents, accountants or attorneys, based upon, arising from, or relating to this
Guaranty, or any other present or future agreement between Coast and Guarantor
or between Coast and Borrower, or any other transaction contemplated hereby or
thereby or relating hereto or thereto, or any other matter, cause or thing
whatsoever, whether or not relating hereto or thereto, occurred, done, omitted
or suffered to be done by Coast, or by Coast's directors, officers, employees,
agents, accountants or attorneys, whether sounding in contract or in tort or
otherwise, shall be barred unless asserted by Guarantor by the commencement of
an action or proceeding in a court of competent jurisdiction within Los Angeles
County, California, by the filing of a complaint within one year after the first
act, occurrence or omission upon which such claim or cause of action, or any
part thereof, is based and service of a summons and complaint on an officer of
Coast or any other person authorized to accept service of process on behalf of
Coast, within 30 days thereafter. Guarantor agrees that such one year period is
a reasonable and sufficient time for Guarantor to investigate and act upon any
such claim or cause of action. The one year period provided herein shall not be
waived, tolled, or extended except by a specific written agreement of Coast.
This provision shall survive any termination of this Guaranty or any other
agreement.

            18. Construction; Severability. If more than one person has executed
this Guaranty, the term "Guarantor" as used herein shall be deemed to refer to
all and any one or more such persons and their obligations hereunder shall be
joint and several. Without limiting the generality of the foregoing, if more
than one person has executed this Guaranty, this Guaranty shall in all respects
be interpreted as though each person signing this Guaranty had signed a separate
Guaranty, and references herein to "other guarantors" or words of similar effect
shall include without limitation other persons signing this Guaranty. As used in
this Guaranty, the term "property" is used in its most comprehensive sense and
shall mean all property of every kind and nature whatsoever, including without
limitation real property, personal property, mixed property, tangible property
and intangible property. Words used herein in the masculine gender shall include
the neuter and feminine gender, words used herein in the neuter gender shall
include the masculine and feminine, words used

                Continuing Guaranty
            --------------------------------------------------------------------

herein in the singular shall include the plural and words used in the plural
shall include the singular, wherever the context so reasonably requires. If any
provision of this Guaranty or the application thereof to any party or
circumstance is held invalid, void, inoperative or unenforceable, the remainder
of this Guaranty and the application of such provision to other parties or
circumstances shall not be affected thereby, the provisions of this Guaranty
being severable in any such instance.

            19. General Provisions. Coast shall have the right to seek recourse
against Guarantor to the full extent provided for herein and in any other
instrument or agreement evidencing obligations of Guarantor to Coast, and
against Borrower to the full extent of the Indebtedness. No election in one form
of action or proceeding, or against any party, or on any obligation, shall
constitute a waiver of Coast's right to proceed in any other form of action or
proceeding or against any other party. The failure of Coast to enforce any of
the provisions of this Guaranty at any time or for any period of time shall not
be construed to be a waiver of any such provision or the right thereafter to
enforce the same. All remedies hereunder shall be cumulative and shall be in
addition to all rights, powers and remedies given to Coast by law or under any
other instrument or agreement. Time is of the essence in the performance by
Guarantor of each and every obligation under this Guaranty. If Borrower is a
corporation, partnership or other entity, Guarantor hereby agrees that Coast
shall have no obligation to inquire into the power or authority of Borrower or
any of its officers, directors, partners, or agents acting or purporting to act
on its behalf, and any Indebtedness made or created in reliance upon the
professed exercise of any such power or authority shall be included in the
Indebtedness guaranteed hereby. This Guaranty is the entire and only agreement
between Guarantor and Coast with respect to the guaranty of the Indebtedness of
Borrower by Guarantor, and all representations, warranties, agreements, or
undertakings heretofore or contemporaneously made, which are not set forth
herein, are superseded hereby. No course of dealings between the parties, no
usage of the trade, and no parol or extrinsic evidence of any nature shall be
used or be relevant to supplement or explain or modify any term or provision of
this Guaranty. There are no conditions to the full effectiveness of this
Guaranty. The terms and provisions hereof may not be waived, altered, modified,
or amended except in a writing executed by Guarantor and a duly authorized
officer of Coast. All rights, benefits and privileges hereunder shall inure to
the benefit of and be enforceable by Coast and its successors and assigns and
shall be binding upon Guarantor and his heirs, executors, administrators,
personal representatives, successors and assigns. Neither the death of Guarantor
nor notice thereof to Coast shall terminate this Guaranty as to his estate, and,
notwithstanding the death of Guarantor or notice thereof to Coast, this Guaranty
shall continue in full force and effect with respect to all Indebtedness,
including without limitation Indebtedness incurred or created after the death of
Guarantor and notice thereof to Coast. Section headings are used herein for
convenience only. Guarantor acknowledges that the same may not describe
completely the subject matter of the applicable Section, and the same shall not
be used in any manner to construe, limit, define or interpret any term or
provision hereof.

            20. Governing Law; Venue and Jurisdiction. This instrument and all
acts and transactions pursuant or relating hereto and all rights and obligations
of the parties hereto shall be governed, construed, and interpreted in
accordance with the internal laws of the State of California. In order to induce
Coast to accept this Guaranty, and as a material part of the consideration
therefor, Guarantor (i) agrees that all actions or proceedings relating directly
or indirectly hereto shall, at the option of Coast, be litigated in courts
located within Los Angeles County, California, (ii) consents to the jurisdiction
of any such court and consents to the service of process in any such action or
proceeding by personal delivery or any other method permitted by law; and (iii)
waives any and all rights Guarantor may have to transfer or change the venue of
any such action or proceeding.

            21. Mutual Waiver of Right to Jury Trial. COAST AND GUARANTOR HEREBY
WAIVE THE RIGHT TO TRIAL BY JURY IN ANY ACTION, CLAIM, LAWSUIT OR PROCEEDING
BASED UPON, ARISING OUT OF, OR IN ANY WAY RELATING TO: (I) THIS GUARANTEE OR ANY
SUPPLEMENT OR AMENDMENT THERETO; OR (II) ANY OTHER PRESENT OR FUTURE INSTRUMENT
OR AGREEMENT BETWEEN COAST AND GUARANTOR ; OR (III) ANY BREACH, CONDUCT, ACTS OR
OMISSIONS OF COAST OR GUARANTOR OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS,
EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSON AFFILIATED WITH OR

                              2800 28th Street, Suite 100

                              Santa Monica, California 90405

            Date:             September 27, 1996

            This Continuing Guaranty is executed by the above-named guarantor
("Guarantor"), as of the above date, in favor of COAST BUSINESS CREDIT, a
division of Southern Pacific Thrift & Loan Association ("Coast"), a California
corporation, with offices at 12121 Wilshire Boulevard, Suite 1111, Los Angeles,
California 90025, with respect to the Indebtedness of Cray Communications, Inc.,
a Delaware corporation ("Borrower").

            1. Continuing Guaranty. Guarantor hereby unconditionally guarantees
and promises to pay on demand to Coast, at the address indicated above, or at
such other address as Coast may direct, in lawful money of the United States,
and to perform for the benefit of Coast, all Indebtedness of Borrower now or
hereafter owing to or held by Coast. As used herein, the term "Indebtedness" is
used in its most comprehensive sense and shall mean and include without
limitation: (a) any and all debts, duties, obligations, liabilities,
representations, warranties and guaranties of Borrower or any one or more of
them, heretofore, now, or hereafter made, incurred, or created, whether directly
to Coast or acquired by Coast by assignment or otherwise, or held by Coast on
behalf of others, however arising, whether voluntary or involuntary, due or not
due, absolute or contingent, liquidated or unliquidated, certain or uncertain,
determined or undetermined, monetary or nonmonetary, written or oral, and
whether Borrower may be liable individually or jointly with others, and
regardless of whether recovery thereon may be or hereafter become barred by any
statute of limitations, discharged or uncollectible in any bankruptcy,
insolvency or other proceeding, or otherwise unenforceable; and (b) any and all
amendments, modifications, renewals and extensions of any or all of the
foregoing, including without limitation amendments, modifications, renewals and
extensions which are evidenced by any new or additional instrument, document or
agreement; and (c) any and all attorneys' fees, court costs, and collection
charges incurred in endeavoring to collect or enforce any of the foregoing
against Borrower, Guarantor, or any other person liable thereon (whether or not
suit be brought) and any other expenses of, for or incidental to collection
thereof. As used herein, the term "Borrower" shall include any successor to the
business and assets of

                Continuing Guaranty
            --------------------------------------------------------------------

Borrower, and shall also include Borrower in its capacity as a debtor or debtor
in possession under the federal Bankruptcy Code, and any trustee, custodian or
receiver for Borrower or any of its assets, should Borrower hereafter become the
subject of any bankruptcy or insolvency proceeding, voluntary or involuntary;
and all indebtedness, liabilities and obligations incurred by any such person
shall be included in the Indebtedness guaranteed hereby. This Guaranty is given
in consideration for credit and other financial accommodations which may, from
time to time, be given by Coast to Borrower in Coast's sole discretion, but
Guarantor acknowledges and agrees that acceptance by Coast of this Guaranty
shall not constitute a commitment of any kind by Coast to extend such credit or
other financial accommodation to Borrower or to permit Borrower to incur
Indebtedness to Coast. All sums due under this Guaranty shall bear interest from
the date due until the date paid at the highest rate charged with respect to any
of the Indebtedness.

            2. Waivers. Guarantor hereby waives: (a) presentment for payment,
notice of dishonor, protest, and notice thereof as to any instrument, and all
other notices and demands to which Guarantor might be entitled, including
without limitation notice of all of the following: the acceptance hereof; the
creation, existence, or acquisition of any Indebtedness; the amount of the
Indebtedness from time to time outstanding; disposition of any property which
secures any or all of the Indebtedness or which secures the obligations of any
other guarantor of any or all of the Indebtedness; any adverse change in
Borrower's financial position; any other fact which might increase Guarantor's
risk; any default, partial payment or non-payment of all or any part of the
Indebtedness; any and all agreements and arrangements between Coast and Borrower
and any changes, modifications, or extensions thereof, and any revocation,
modification or release of any guaranty of any or all of the Indebtedness by any
person (including without limitation any other person signing this Guaranty);
(b) any right to require Coast to institute suit against, or to exhaust its
rights and remedies against, Borrower or any other person, or to proceed against
any property of any kind which secures all or any part of the Indebtedness, or
to exercise any right of offset or other right with respect to any reserves,
credits or deposit accounts held by or maintained with Coast or any indebtedness
of Coast to Borrower, or to exercise any other right or power, or pursue any
other remedy Coast may have; (c) any defense arising by reason of any disability
or other defense of Borrower or any other guarantor or any endorser, co-maker or
other person, or by reason of the cessation from any cause whatsoever of any
liability of Borrower or any other guarantor or any endorser, co-maker or other
person, with respect to all or any part of the Indebtedness, or by reason of any
act or omission of Coast or others which directly or indirectly results in the
discharge or release of Borrower or any other guarantor or any other person or
any Indebtedness or any security therefor, whether by operation of law or
otherwise; (d) any defense arising by reason of any failure of Coast to obtain,
perfect, maintain or keep in force any security interest in, or lien or
encumbrance upon, any property of Borrower or any other person; (e) any defense
based upon any failure of Coast to give Guarantor notice of any sale or other
disposition of any property securing any or all of the Indebtedness, or any
defects in any such notice that may be given, or any failure of Coast to comply
with any provision of applicable law in enforcing any security interest in or
lien upon any property securing any or all of the Indebtedness including, but
not limited to, any failure by Coast to dispose of any property securing any or
all of the Indebtedness in a commercially reasonable manner; (f) any defense
based upon or arising out of any bankruptcy, insolvency, reorganization,
arrangement, readjustment of debt, liquidation or dissolution proceeding
commenced by or against Borrower or any other guarantor or any endorser,
co-maker or other person, including without limitation any discharge of, or bar
against collecting, any of the Indebtedness (including without limitation any
interest thereon), in or as a result of any such proceeding; and (g) the benefit
of any and all statutes of limitation with respect to any action based upon,
arising out of or related to this Guaranty. Until all of the Indebtedness has
been paid, performed, and discharged in full, nothing shall discharge or satisfy
the liability of Guarantor hereunder except the full performance and payment of
all of the Indebtedness. If any claim is ever made upon Coast for repayment or
recovery of any amount or amounts received by Coast in payment of or on account
of any of the Indebtedness, because of any claim that any such payment
constituted a preferential transfer or fraudulent conveyance, or for any other
reason whatsoever, and Coast repays all or part of said amount by reason of any
judgment, decree or order of any court or administrative body having
jurisdiction over Coast or any of its property, or by reason of any settlement
or compromise of any such claim effected by Coast with any such claimant
(including without limitation the Borrower), then and in any such event,
Guarantor agrees that any such judgment, decree, order, settlement and
compromise shall be binding upon Guarantor, notwithstanding any revocation or
release of this Guaranty or the cancellation of any note or other instrument
evidencing any of the Indebtedness, or any

                Continuing Guaranty
            --------------------------------------------------------------------

release of any of the Indebtedness, and the Guarantor shall be and remain liable
to Coast under this Guaranty for the amount so repaid or recovered, to the same
extent as if such amount had never originally been received by Coast, and the
provisions of this sentence shall survive, and continue in effect,
notwithstanding any revocation or release of this Guaranty. Until all of the
Indebtedness has been irrevocably paid and performed in full, Guarantor hereby
expressly and unconditionally waives all rights of subrogation, reimbursement
and indemnity of every kind against Borrower, and all rights of recourse to any
assets or property of Borrower, and all rights to any collateral or security
held for the payment and performance of any Indebtedness, including (but not
limited to) any of the foregoing rights which Guarantor may have under any
present or future document or agreement with any Borrower or other person, and
including (but not limited to) any of the foregoing rights which Guarantor may
have under any equitable doctrine of subrogation, implied contract, or unjust
enrichment, or any other equitable or legal doctrine. Neither Coast, nor any of
its directors, officers, employees, agents, attorneys or any other person
affiliated with or representing Coast shall be liable for any claims, demands,
losses or damages, of any kind whatsoever, made, claimed, incurred or suffered
by Guarantor or any other party through the ordinary negligence of Coast, or any
of its directors, officers, employees, agents, attorneys or any other person
affiliated with or representing Coast.

            3. Consents. Guarantor hereby consents and agrees that, without
notice to or by Guarantor and without affecting or impairing in any way the
obligations or liability of Guarantor hereunder, Coast may, from time to time
before or after revocation of this Guaranty, do any one or more of the following
in Coast's sole and absolute discretion: (a) accelerate, accept partial payments
of, compromise or settle, renew, extend the time for the payment, discharge, or
performance of, refuse to enforce, and release all or any parties to, any or all
of the Indebtedness; (b) grant any other indulgence to Borrower or any other
person in respect of any or all of the Indebtedness or any other matter; (c)
accept, release, waive, surrender, enforce, exchange, modify, impair, or extend
the time for the performance, discharge, or payment of, any and all property of
any kind securing any or all of the Indebtedness or any guaranty of any or all
of the Indebtedness, or on which Coast at any time may have a lien, or refuse to
enforce its rights or make any compromise or settlement or agreement therefor in
respect of any or all of such property; (d) substitute or add, or take any
action or omit to take any action which results in the release of, any one or
more endorsers or guarantors of all or any part of the Indebtedness, including,
without limitation one or more parties to this Guaranty, regardless of any
destruction or impairment of any right of contribution or other right of
Guarantor; (e) amend, alter or change in any respect whatsoever any term or
provision relating to any or all of the Indebtedness, including the rate of
interest thereon; (f) apply any sums received from Borrower, any other
guarantor, endorser, or co-signer, or from the disposition of any collateral or
security, to any indebtedness whatsoever owing from such person or secured by
such collateral or security, in such manner and order as Coast determines in its
sole discretion, and regardless of whether such indebtedness is part of the
Indebtedness, is secured, or is due and payable; (g) apply any sums received
from Guarantor or from the disposition of any collateral or security securing
the obligations of Guarantor, to any of the Indebtedness in such manner and
order as Coast determines in its sole discretion, regardless of whether or not
such Indebtedness is secured or is due and payable. Guarantor consents and
agrees that Coast shall be under no obligation to marshal any assets in favor of
Guarantor, or against or in payment of any or all of the Indebtedness. Guarantor
further consents and agrees that Coast shall have no duties or responsibilities
whatsoever with respect to any property securing any or all of the Indebtedness.
Without limiting the generality of the foregoing, Coast shall have no obligation
to monitor, verify, audit, examine, or obtain or maintain any insurance with
respect to, any property securing any or all of the Indebtedness.

            4. Account Stated. Coast's books and records showing the account
between it and the Borrower shall be admissible in evidence in any action or
proceeding as prima facie proof of the items therein set forth. Coast's monthly
statements rendered to the Borrower shall be binding upon the Guarantor (whether
or not the Guarantor receives copies thereof), and shall constitute an account
stated between Coast and the Borrower, unless Coast receives a written statement
of the Borrower's exceptions within 30 days after the statement was mailed to
the Borrower. The Guarantor assumes full responsibility for obtaining copies of
such monthly statements from the Borrower, if the Guarantor desires such copies.

            5. Exercise of Rights and Remedies; Foreclosure of Trust Deeds.

                Continuing Guaranty
            --------------------------------------------------------------------

consents and agrees that, without notice to or by Guarantor and without
affecting or impairing in any way the obligations or liability of Guarantor
hereunder, Coast may, from time to time, before or after revocation of this
Guaranty, exercise any right or remedy it may have with respect to any or all of
the Indebtedness or any property securing any or all of the Indebtedness or any
guaranty thereof, including without limitation judicial foreclosure, nonjudicial
foreclosure, exercise of a power of sale, and taking a deed, assignment or
transfer in lieu of foreclosure as to any such property, and Guarantor expressly
waives any defense based upon the exercise of any such right or remedy,
notwithstanding the effect thereof upon any of Guarantor's rights, including
without limitation, any destruction of Guarantor's right of subrogation against
Borrower and any destruction of Guarantor's right of contribution or other right
against any other guarantor of any or all of the Indebtedness or against any
other person, whether by operation of Sections 580a, 580d or 726 of the
California Code of Civil Procedure, or any comparable provisions of the laws of
any other jurisdiction, or any other statutes or rules of law now or hereafter
in effect, or otherwise. Without limiting the generality of the foregoing, (a)
Guarantor waives all rights and defenses arising out of an election of remedies
by Coast, even though that election of remedies, such as a nonjudicial
foreclosure with respect to security for any of the Indebtedness, has destroyed
the guarantor's rights of subrogation and reimbursement against the principal by
the operation of Section 580d of the Code of Civil Procedure or otherwise. (b)
Guarantor further waives all rights and defenses arising out of an election of
remedies by Coast, even though that election of remedies, such as a nonjudicial
foreclosure with respect to security for any of the Indebtedness, has destroyed
the guarantor's rights of subrogation, reimbursement and contribution against
any other guarantor of the guaranteed obligation, by the operation of Section
580d of the Code of Civil Procedure or otherwise. (c) Guarantor understands that
if Coast forecloses any present or future trust deed, which secures any or all
of the Indebtedness or which secures any other guaranty of any or all of the
Indebtedness, by nonjudicial foreclosure, Guarantor may, as a result, have a
complete defense to liability under this Guaranty, based on the legal doctrine
of estoppel and Sections 580a, 580d or 726 of the California Code of Civil
Procedure, and Guarantor hereby expressly waives all such defenses. (d)
Guarantor understands and agrees that, in the event Coast in its sole discretion
forecloses any trust deed now or hereafter securing any or all of the
Indebtedness, by nonjudicial foreclosure, Guarantor will remain liable to Coast
for any deficiency, even though Guarantor will lose his right of subrogation
against the Borrower, and even though Guarantor will be unable to recover from
the Borrower the amount of the deficiency for which Guarantor is liable, and
even though Guarantor may have retained his right of subrogation against
Borrower if Coast had foreclosed said trust deed by judicial foreclosure as
opposed to nonjudicial foreclosure, and even though absent the waivers set forth
herein Guarantor may have had a complete defense to any liability for any
deficiency hereunder. (e) Guarantor understands and agrees that, in the event
Coast in its sole discretion forecloses any trust deed now or hereafter securing
any other guaranty of any or all of the Indebtedness, by nonjudicial
foreclosure, Guarantor will remain liable to Coast for any deficiency, even
though Guarantor will lose his right of subrogation or contribution against the
other guarantor, and even though Guarantor will be unable to recover from the
other guarantor any part of the deficiency for which Guarantor is liable, and
even though Guarantor may have retained his right of subrogation or contribution
against the other guarantor if Coast had foreclosed said trust deed by judicial
foreclosure as opposed to nonjudicial foreclosure, and even though absent the
waivers set forth herein Guarantor may have had a complete defense to any
liability for any deficiency hereunder.

            6. Acceleration. Notwithstanding the terms of all or any part of the
Indebtedness, the obligations of the Guarantor hereunder to pay and perform all
of the Indebtedness shall, at the option of Coast, immediately become due and
payable, without notice, and without regard to the expressed maturity of any of
the Indebtedness, in the event: (a) any warranty, representation, statement,
report, or certificate made or delivered to Coast by Borrower or Guarantor, or
any of their respective officers, partners, employees, or agents, is incorrect,
false, untrue, or misleading when given in any material respect; or (b) Borrower
or Guarantor shall fail to pay or perform when due all or any part of the
Indebtedness; or (c) Guarantor shall fail to pay or perform within 5 days after
the same is due any indebtedness or obligation of Guarantor to Coast or to any
parent, subsidiary or corporate affiliate of Coast, whether under this Guaranty
or any other instrument, document, or agreement heretofore or hereafter entered
into; or (d) there occurs in Coast's judgment a material impairment of the
prospect of payment or performance of any or all of the Indebtedness; or (e) any
event shall occur which does result in the acceleration of the maturity of any
indebtedness of Borrower or Guarantor to others (regardless of any requirement
of notice, opportunity to cure or other condition prior to the exercise of any
right of acceleration); or (f) Borrower or Guarantor shall fail promptly to
perform or comply with any term or


                                      -5-
<PAGE>

                                                           Coast Business Credit
                Continuing Guaranty
            --------------------------------------------------------------------

condition of any agreement with any third party which does or may result in a
material adverse effect on the business of Borrower or Guarantor unless timely
cured or waived in writing by such third party; or (g) there shall be made or
exist any levy, assessment, attachment, seizure, lien, or encumbrance for any
cause or reason whatsoever upon all or any part of the property of Borrower or
Guarantor (unless discharged by payment, release or bond not more than ten days
after such event has occurred); or (h) there shall occur the dissolution,
termination of existence, insolvency, or business failure of Borrower or
Guarantor, or the appointment of a receiver, trustee or custodian for Borrower
or Guarantor or all or any part of the property of either of them, or the
assignment for the benefit of creditors by Borrower or Guarantor, or the
commencement of any proceeding by or against Borrower or Guarantor under any
reorganization, bankruptcy, insolvency, arrangement, readjustment of debt,
dissolution or liquidation law or statute of any jurisdiction, now or hereafter
in effect; or (i) Borrower or Guarantor shall be deceased or declared
incompetent by any court or a guardian or conservator shall be appointed for
either of them or for the property of either of them; or (j) Guarantor or
Borrower shall generally not pay their respective debts as they become due or
shall enter into any agreement (whether written or oral), or offer to enter into
any such agreement, with all or a significant number of its creditors regarding
any moratorium or other indulgence with respect to its debts or the
participation of such creditors or their representatives in the supervision,
management, or control of the business of either of them; or (k) Borrower or
Guarantor shall conceal, remove or permit to be concealed or removed any part of
its property, with intent to hinder, delay or defraud its creditors, or make or
suffer any transfer of any of its property which may be fraudulent under any
bankruptcy, fraudulent conveyance or similar law, or shall make any transfer of
its property to or for the benefit of any creditor at a time when other
creditors similarly situated have not been paid; or (l) the board of directors
or shareholders of Borrower or Guarantor shall adopt any resolution or plan for
its dissolution or the liquidation of all or substantially all of its assets; or
(m) Guarantor shall revoke this Guaranty or contest or deny liability under this
Guaranty. All of the foregoing are hereinafter referred to as "Events of
Default".

            7. Right to Attachment Remedy. Guarantor agrees that,
notwithstanding the existence of any property securing any or all of the
Indebtedness, Coast shall have all of the rights of an unsecured creditor of
Guarantor, including without limitation the right to obtain a temporary
protective order and writ of attachment against Guarantor with respect to any
sums due under this Guaranty. Guarantor further agrees that in the event any
property secures the obligations of Guarantor under this Guaranty, to the extent
that Coast, in its sole and absolute discretion, determines prior to the
disposition of such property that the amount to be realized by Coast therefrom
may be less than the indebtedness of the Guarantor under this Guaranty, Coast
shall have all the rights of an unsecured creditor against Guarantor, including
without limitation the right of Coast, prior to the disposition of said
property, to obtain a temporary protective order and writ of attachment against
Guarantor. Guarantor waives the benefit of Section 483.010(b) of the California
Code of Civil Procedure and of any and all other statutes and rules of law now
or hereafter in effect requiring Coast to first resort to or exhaust all such
collateral before seeking or obtaining any attachment remedy against Guarantor.
Coast shall have no liability to Guarantor as a result thereof, whether or not
the actual deficiency realized by Coast is less than the anticipated deficiency
on the basis of which Coast obtains a temporary protective order or writ of
attachment.

            8. Indemnity. Guarantor hereby agrees to indemnify Coast and hold
Coast harmless from and against any and all claims, debts, liabilities, demands,
obligations, actions, causes of action, penalties, costs and expenses (including
without limitation attorneys' fees), of every nature, character and description,
which Coast may sustain or incur based upon or arising out of any of the
Indebtedness, any actual or alleged failure to collect and pay over any
withholding or other tax relating to Borrower or its employees, any relationship
or agreement between Coast and Borrower, any actual or alleged failure of Coast
to comply with any writ of attachment or other legal process relating to
Borrower or any of its property, or any other matter, cause or thing whatsoever
occurred, done, omitted or suffered to be done by Coast relating in any way to
Borrower or the Indebtedness (except any such amounts sustained or incurred as
the result of the gross negligence or willful misconduct of Coast or any of its
directors, officers, employees, agents, attorneys, or any other person
affiliated with or representing Coast). Notwithstanding any provision in this
Guaranty to the contrary, the indemnity agreement set forth in this Section
shall survive any termination or revocation of this Guaranty and shall for all
purposes continue in full force and effect.

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

            9. Subordination. Any and all debts, liabilities and obligations
owing from Borrower to Guarantor including any security for and guaranties of
any such obligations, whether now existing or hereafter arising, are hereby
subordinated in right of payment to the prior payment in full of all of the
Indebtedness. Except as permitted in that certain Subordination Agreement
between Guarantor and Coast dated as of September, 1996, and any written
amendments thereto, no payment in respect of any such subordinated obligations
shall at any time be made to or accepted by Guarantor if at the time of such
payment any Indebtedness is outstanding unless Coast, in its sole discretion,
agrees to such payment in writing. The agreement by Coast to a payment on
account of subordinated debt shall not constitute an agreement to the payment of
any other subordinated. If any Event of Default has occurred, all debts,
liabilities and obligations owing from Borrower to Guarantor shall be
subordinated, Borrower and any assignee, trustee in bankruptcy, receiver, or any
other person having custody or control over any or all of Borrower's property
are hereby authorized and directed to pay to Coast the entire unpaid balance of
the Indebtedness before making any payments whatsoever to Guarantor, whether as
a creditor, shareholder, or otherwise; and insofar as may be necessary for that
purpose, Guarantor hereby assigns and transfers to Coast all rights to any and
all debts, liabilities and obligations owing from Borrower to Guarantor,
including any security for and guaranties of any such obligations, whether now
existing or hereafter arising, including without limitation any payments,
dividends or distributions out of the business or assets of Borrower. Any
amounts received by Guarantor in violation of the foregoing provisions shall be
received and held as trustee for the benefit of Coast and shall forthwith be
paid over to Coast to be applied to the Indebtedness in such order and sequence
as Coast shall in its sole discretion determine, without limiting or affecting
any other right or remedy which Coast may have hereunder or otherwise and
without otherwise affecting the liability of Guarantor hereunder. Guarantor
hereby expressly waives any right to set-off or assert any counterclaim against
Borrower.

            10. Revocation. This is a Continuing Guaranty relating to all of the
Indebtedness, including Indebtedness arising under successive transactions which
from time to time continue the Indebtedness or renew it after it has been
satisfied. Guarantor waives all benefits of California Civil Code Section 2815,
and agrees that the obligations of Guarantor hereunder may not be terminated or
revoked in any manner except by giving written notice of revocation to Coast at
its address above by registered first-class U.S. mail, postage prepaid, return
receipt requested, and only as to new loans made by Coast to Borrower after
actual receipt of such written notice by Coast. No termination or revocation of
this Guaranty shall be effective until actual receipt of said written notice of
revocation by Coast. Notwithstanding such written notice of revocation or any
other act of Guarantor or any other event or circumstance, Guarantor agrees that
this Guaranty and all consents, waivers and other provisions hereof shall
continue in full force and effect as to any and all Indebtedness which is
outstanding on or before the day following actual receipt of said written notice
of revocation by Coast, and all extensions, renewals and modifications of said
Indebtedness (including without limitation amendments, extensions, renewals and
modifications which are evidenced by new or additional instruments, documents or
agreements executed before receipt of revocation, and all attorneys' fees, court
costs and collection charges, incurred before or after receipt of revocation, in
endeavoring to collect or enforce any of the foregoing against Borrower,
Guarantor or any other person liable thereon (whether or not suit be brought)
and any other expenses of, for or incidental to collection thereof.

            11. Independent Liability. Guarantor hereby agrees that one or more
successive or concurrent actions may be brought hereon against Guarantor, in the
same action in which Borrower may be sued or in separate actions, as often as
deemed advisable by Coast. The liability of Guarantor hereunder is exclusive and
independent of any other guaranty of any or all of the Indebtedness whether
executed by Guarantor or by any other guarantor (including without limitation
any other persons signing this Guaranty). The liability of Guarantor hereunder
shall not be affected, revoked, impaired, or reduced by any one or more of the
following: (a) the fact that the Indebtedness exceeds the maximum amount of
Guarantor's liability, if any, specified herein or elsewhere (and no agreement
specifying a maximum amount of Guarantor's liability shall be enforceable unless
set forth in a writing signed by Coast or set forth in this Guaranty); or (b)
any direction as to the application of payment by Borrower or by any other
party; or (c) any other continuing or restrictive guaranty or undertaking or any
limitation on the liability of any other guarantor (whether under this Guaranty
or under any other agreement); or (d) any payment on or reduction of any such
other guaranty or undertaking; or (e) any revocation, amendment, modification or
release of any such other guaranty or undertaking; or (f) any

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

dissolution or termination of, or increase, decrease, or change in membership of
any Guarantor which is a partnership. Guarantor hereby expressly represents that
he was not induced to give this Guaranty by the fact that there are or may be
other guarantors either under this Guaranty or otherwise, and Guarantor agrees
that any release of any one or more of such other guarantors shall not release
Guarantor from his obligations hereunder either in full or to any lesser extent.
If Guarantor is a married person, Guarantor hereby expressly agrees that
recourse may be had against his or her separate property for all of his or her
obligations hereunder.

            12. Financial Condition of Borrower. Guarantor is fully aware of the
financial condition of Borrower and is executing and delivering this Guaranty at
Borrower's request and based solely upon his own independent investigation of
all matters pertinent hereto, and Guarantor is not relying in any manner upon
any representation or statement of Coast with respect thereto. Guarantor
represents and warrants that he is in a position to obtain, and Guarantor hereby
assumes full responsibility for obtaining, any additional information concerning
Borrower's financial condition and any other matter pertinent hereto as
Guarantor may desire, and Guarantor is not relying upon or expecting Coast to
furnish to him any information now or hereafter in Coast's possession concerning
the same or any other matter. By executing this Guaranty, Guarantor knowingly
accepts the full range of risks encompassed within a contract of continuing
guaranty, which risks Guarantor acknowledges include without limitation the
possibility that Borrower will incur additional Indebtedness for which Guarantor
will be liable hereunder after Borrower's financial condition or ability to pay
such Indebtedness has deteriorated and/or after bankruptcy or insolvency
proceedings have been commenced by or against Borrower. Guarantor shall have no
right to require Coast to obtain or disclose any information with respect to the
Indebtedness, the financial condition or character of Borrower, the existence of
any collateral or security for any or all of the Indebtedness, the filing by or
against Borrower of any bankruptcy or insolvency proceeding, the existence of
any other guaranties of all or any part of the Indebtedness, any action or
non-action on the part of Coast, Borrower, or any other person, or any other
matter, fact, or occurrence.

            13. Reports and Financial Statements of Guarantor. Guarantor shall,
at its sole cost and expense, at any time and from time to time, prepare or
cause to be prepared, and provide to Coast upon Coast's request (i) such
financial statements and reports concerning Guarantor for such periods of time
as Coast may designate, (ii) any other information concerning Guarantor's
business, financial condition or affairs as Coast may request, and (iii) copies
of any and all foreign, federal, state and local tax returns and reports of or
relating to Guarantor as Coast may from time to time request. Guarantor hereby
intentionally and knowingly waives any and all rights and privileges it may have
not to divulge or deliver said tax returns, reports and other information which
are requested by Coast hereunder or in any litigation in which Coast may be
involved relating directly or indirectly to Borrower or to Guarantor. Guarantor
further agrees immediately to give written notice to Coast of any adverse change
in Guarantor's financial condition and of any condition or event which
constitutes an Event of Default under this Guaranty. All reports and information
furnished to Coast hereunder shall be complete, accurate and correct in all
respects. Whenever requested, Guarantor shall further deliver to Coast a
certificate signed by Guarantor (and, if Guarantor is a partnership, by all
general partners of Guarantor, in their individual capacities, and, if Guarantor
is a corporation, by the president and secretary of Guarantor, in their
individual capacities) warranting and representing that all reports, financial
statements and other documents and information delivered or caused to be
delivered to Coast under this Guaranty, are complete, correct and thoroughly and
accurately present the financial condition of Guarantor, and that there exists
on the date of delivery of said certificate to Coast no condition or event which
constitutes an Event of Default under this Guaranty.

            14. Representations and Warranties. Guarantor hereby represents and
warrants that (i) it is in Guarantor's direct interest to assist Borrower in
procuring credit, because Borrower is an affiliate of Guarantor, furnishes goods
or services to Guarantor, purchases or acquires goods or services from
Guarantor, and/or otherwise has a direct or indirect corporate or business
relationship with Guarantor, (ii) this Guaranty has been duly and validly
authorized, executed and delivered and constitutes the valid and binding
obligation of Guarantor, enforceable in accordance with its terms, and (iii) the
execution and delivery of this Guaranty does not violate or constitute a default
under (with or without the giving of notice, the passage of time, or both) any
order, judgment, decree, instrument or agreement to which Guarantor is a party
or by which it or its assets are affected or bound.

                Continuing Guaranty
            --------------------------------------------------------------------

            15. Costs. Whether or not suit be instituted, Guarantor agrees to
reimburse Coast on demand for all reasonable attorneys' fees and all other
reasonable costs and expenses incurred by Coast in enforcing this Guaranty, or
arising out of or relating in any way to this Guaranty, or in enforcing any of
the Indebtedness against Borrower, Guarantor, or any other person, or in
connection with any property of any kind securing all or any part of the
Indebtedness. Without limiting the generality of the foregoing, and in addition
thereto, Guarantor shall reimburse Coast on demand for all reasonable attorneys'
fees and costs Coast incurs in any way relating to Guarantor, Borrower or the
Indebtedness, in order to: obtain legal advice; enforce or seek to enforce any
of its rights; commence, intervene in, respond to, or defend any action or
proceeding; file, prosecute or defend any claim or cause of action in any action
or proceeding (including without limitation any probate claim, bankruptcy claim,
third-party claim, secured creditor claim, reclamation complaint, and complaint
for relief from any stay under the Bankruptcy Code or otherwise); protect,
obtain possession of, sell, lease, dispose of or otherwise enforce any security
interest in or lien on any property of any kind securing any or all of the
Indebtedness; or represent Coast in any litigation with respect to Borrower's or
Guarantor's affairs. In the event either Coast or Guarantor files any lawsuit
against the other predicated on a breach of this Guaranty, the prevailing party
in such action shall be entitled to recover its attorneys' fees and costs of
suit from the non-prevailing party.

            16. Notices. Any notice which a party shall be required or shall
desire to give to the other hereunder (except for notice of revocation, which
shall be governed by Section 10 of this Guaranty) shall be given by personal
delivery or by telecopier or by depositing the same in the United States mail,
first class postage pre-paid, addressed to Coast at its address set forth in the
heading of this Guaranty and to Guarantor at his address set forth under his
signature hereon, and such notices shall be deemed duly given on the date of
personal delivery or one day after the date telecopied or 3 business days after
the date of mailing as aforesaid. Coast and Guarantor may change their address
for purposes of receiving notices hereunder by giving written notice thereof to
the other party in accordance herewith. Guarantor shall give Coast immediate
written notice of any change in his address.

            17. Claims. Guarantor agrees that any claim or cause of action by
Guarantor against Coast, or any of Coast's directors, officers, employees,
agents, accountants or attorneys, based upon, arising from, or relating to this
Guaranty, or any other present or future agreement between Coast and Guarantor
or between Coast and Borrower, or any other transaction contemplated hereby or
thereby or relating hereto or thereto, or any other matter, cause or thing
whatsoever, whether or not relating hereto or thereto, occurred, done, omitted
or suffered to be done by Coast, or by Coast's directors, officers, employees,
agents, accountants or attorneys, whether sounding in contract or in tort or
otherwise, shall be barred unless asserted by Guarantor by the commencement of
an action or proceeding in a court of competent jurisdiction within Los Angeles
County, California, by the filing of a complaint within one year after the first
act, occurrence or omission upon which such claim or cause of action, or any
part thereof, is based and service of a summons and complaint on an officer of
Coast or any other person authorized to accept service of process on behalf of
Coast, within 30 days thereafter. Guarantor agrees that such one year period is
a reasonable and sufficient time for Guarantor to investigate and act upon any
such claim or cause of action. The one year period provided herein shall not be
waived, tolled, or extended except by a specific written agreement of Coast.
This provision shall survive any termination of this Guaranty or any other
agreement.

            18. Construction; Severability. If more than one person has executed
this Guaranty, the term "Guarantor" as used herein shall be deemed to refer to
all and any one or more such persons and their obligations hereunder shall be
joint and several. Without limiting the generality of the foregoing, if more
than one person has executed this Guaranty, this Guaranty shall in all respects
be interpreted as though each person signing this Guaranty had signed a separate
Guaranty, and references herein to "other guarantors" or words of similar effect
shall include without limitation other persons signing this Guaranty. As used in
this Guaranty, the term "property" is used in its most comprehensive sense and
shall mean all property of every kind and nature whatsoever, including without
limitation real property, personal property, mixed property, tangible property
and intangible property. Words used herein in the masculine gender shall include
the neuter and feminine gender, words used herein in the neuter gender shall
include the masculine and feminine, words used

                Continuing Guaranty
            --------------------------------------------------------------------

herein in the singular shall include the plural and words used in the plural
shall include the singular, wherever the context so reasonably requires. If any
provision of this Guaranty or the application thereof to any party or
circumstance is held invalid, void, inoperative or unenforceable, the remainder
of this Guaranty and the application of such provision to other parties or
circumstances shall not be affected thereby, the provisions of this Guaranty
being severable in any such instance.

            19. General Provisions. Coast shall have the right to seek recourse
against Guarantor to the full extent provided for herein and in any other
instrument or agreement evidencing obligations of Guarantor to Coast, and
against Borrower to the full extent of the Indebtedness. No election in one form
of action or proceeding, or against any party, or on any obligation, shall
constitute a waiver of Coast's right to proceed in any other form of action or
proceeding or against any other party. The failure of Coast to enforce any of
the provisions of this Guaranty at any time or for any period of time shall not
be construed to be a waiver of any such provision or the right thereafter to
enforce the same. All remedies hereunder shall be cumulative and shall be in
addition to all rights, powers and remedies given to Coast by law or under any
other instrument or agreement. Time is of the essence in the performance by
Guarantor of each and every obligation under this Guaranty. If Borrower is a
corporation, partnership or other entity, Guarantor hereby agrees that Coast
shall have no obligation to inquire into the power or authority of Borrower or
any of its officers, directors, partners, or agents acting or purporting to act
on its behalf, and any Indebtedness made or created in reliance upon the
professed exercise of any such power or authority shall be included in the
Indebtedness guaranteed hereby. This Guaranty is the entire and only agreement
between Guarantor and Coast with respect to the guaranty of the Indebtedness of
Borrower by Guarantor, and all representations, warranties, agreements, or
undertakings heretofore or contemporaneously made, which are not set forth
herein, are superseded hereby. No course of dealings between the parties, no
usage of the trade, and no parol or extrinsic evidence of any nature shall be
used or be relevant to supplement or explain or modify any term or provision of
this Guaranty. There are no conditions to the full effectiveness of this
Guaranty. The terms and provisions hereof may not be waived, altered, modified,
or amended except in a writing executed by Guarantor and a duly authorized
officer of Coast. All rights, benefits and privileges hereunder shall inure to
the benefit of and be enforceable by Coast and its successors and assigns and
shall be binding upon Guarantor and his heirs, executors, administrators,
personal representatives, successors and assigns. Neither the death of Guarantor
nor notice thereof to Coast shall terminate this Guaranty as to his estate, and,
notwithstanding the death of Guarantor or notice thereof to Coast, this Guaranty
shall continue in full force and effect with respect to all Indebtedness,
including without limitation Indebtedness incurred or created after the death of
Guarantor and notice thereof to Coast. Section headings are used herein for
convenience only. Guarantor acknowledges that the same may not describe
completely the subject matter of the applicable Section, and the same shall not
be used in any manner to construe, limit, define or interpret any term or
provision hereof.

            20. Governing Law; Venue and Jurisdiction. This instrument and all
acts and transactions pursuant or relating hereto and all rights and obligations
of the parties hereto shall be governed, construed, and interpreted in
accordance with the internal laws of the State of California. In order to induce
Coast to accept this Guaranty, and as a material part of the consideration
therefor, Guarantor (i) agrees that all actions or proceedings relating directly
or indirectly hereto shall, at the option of Coast, be litigated in courts
located within Los Angeles County, California, (ii) consents to the jurisdiction
of any such court and consents to the service of process in any such action or
proceeding by personal delivery or any other method permitted by law; and (iii)
waives any and all rights Guarantor may have to transfer or change the venue of
any such action or proceeding.

            21. Mutual Waiver of Right to Jury Trial. COAST AND GUARANTOR HEREBY
WAIVE THE RIGHT TO TRIAL BY JURY IN ANY ACTION, CLAIM, LAWSUIT OR PROCEEDING
BASED UPON, ARISING OUT OF, OR IN ANY WAY RELATING TO: (I) THIS GUARANTEE OR ANY
SUPPLEMENT OR AMENDMENT THERETO; OR (II) ANY OTHER PRESENT OR FUTURE INSTRUMENT
OR AGREEMENT BETWEEN COAST AND GUARANTOR ; OR (III) ANY BREACH, CONDUCT, ACTS OR
OMISSIONS OF COAST OR GUARANTOR OR ANY OF THEIR RESPECTIVE DIRECTORS, OFFICERS,
EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER PERSON AFFILIATED WITH OR

             Subordination Agreement

Borrower:               Cray Communications, Inc., a Delaware corporation
Address:                9020 Junction Drive
                        Annapolis Junction, MD 20791

Creditor/Investor:      B&T Holdings, Inc., a Delaware corporation
                        2800 28th Street, Suite 100
                        Santa Monica, California 90405

Date:                   September 27, 1996

            This Subordination Agreement is executed by the above-named
Subordinating Creditor. ("Subordinating Creditor") in favor of Coast Business
Credit, a division of Southern Pacific Thrift & Loan Association ("Coast"),
whose address is 12121 Wilshire Blvd., Los Angeles, California, with respect to
the above-named Borrower ("Borrower"). In order to induce Coast to extend or
continue to extend financing to the Borrower (but without obligation on Coast's
part to do so), the Subordinating Creditor hereby agrees as follows:

1. Subordination of Debt and Capital Subordinating Creditor hereby subordinates
payment by the Borrower of any and all indebtedness, liabilities, guarantees and
other obligations of the Borrower to Subordinating Creditor and return of
Capital or Distributions now existing or hereafter arising (collectively, the
"Subordinated Amounts"), to the payment to Coast, in full in cash, of all
indebtedness, liabilities, guarantees and other obligations of the Borrower to
Coast, now existing or hereafter arising (including without limitation any
interest, charges and other sums accruing after the filing of a petition by or
against Borrower under the Bankruptcy Code) (the "Coast Debt").

      Subordinating Creditor represents and warrants that it has not transferred
or assigned the Subordinated Amounts or given any other subordination agreement
in respect thereof, and that it will not do so without prior written notice to
Coast and without making such transfer or assignment or subordination expressly
subject to this Agreement. Subordinating Creditor agrees not to ask for, demand,
sue for, take or receive all or any part of the Subordinated Amounts nor any
security therefor unless and until all of the Coast Debt has been paid and
performed in full, in cash; provided that, so long as no Event of Default and no
event which, with notice or passage of time or both, would constitute an Event
of Default under any present or future document, instrument or agreement
evidencing, securing or relating to the Coast Debt, both before and after giving
effect to the following payments, Subordinated Creditor may accept payment of
the following amounts on the Subordinated Amounts: Subordinating Creditor may
accept dividends declared by Borrower and repayment of all or part of the
Subordinated Amounts provided (a) such payments constitute ordinary course of
business transactions, (b) such payments would not constitute an event of
default and no event which, with notice or passage of time or both, would
constitute an event of default under any present or future document, instrument
or agreement between Borrower, Subordinating Creditor or any affiliate, on the
one hand and a party other than Coast on the other hand, (c) all such payments
are reported to Coast on a monthly basis, or more frequently if requested by
Coast, and (d) Coast has not given notice to Subordinating Creditor that Coast
has revoked the authorization of Subordinating Creditor to accept such dividends
or repayments of the Subordinated Amounts, which revocation may be made by Coast
if Coast in good faith believes that revocation is or may be necessary to avoid
or reduce the risk of a material adverse change or impairment of Coast's rights
or financial interests. Coast may further limit or condition dividends or
repayments of the Subordinated Amounts upon such terms as Coast, in its sole
discretion, deems appropriate, including, but not limited to, imposing dollar
limits and requiring advance notice to Coast of proposed dividends and
repayments in amounts which Coast, in its sole discretion, deems material.

                Loan and Security Agreement
            --------------------------------------------------------------------

Subordinating Creditor further agrees that upon any distribution of the assets
or readjustment of the indebtedness of the Borrower whether by reason of
liquidation, composition, bankruptcy, arrangement, receivership, assignment for
the benefit of creditors or any other action or proceeding involving the
readjustment of all or any of the Subordinated Amounts, or the application of
the assets of the Borrower to the payment or liquidation thereof, Coast shall be
entitled to receive payment in full in cash of all of the Coast Debt prior to
the payment of all or any part of the Subordinated Amounts, and in order to
enable Coast to enforce its rights hereunder in any such action or proceeding,
Coast is hereby irrevocably authorized and empowered in its discretion (but
without any obligation on its part) to make and present for and on behalf of
Subordinating Creditor such proofs of claim and proofs of interest against the
Borrower on account of the Subordinated Amounts as Coast may deem expedient or
proper and to vote such proofs of claim and proofs of interest in any such
proceeding and to receive and collect any and all dividends or other payments or
disbursements made thereon in whatever form the same may be paid or issued and
to apply same on account of the Coast Debt. Subordinating Creditor further
agrees to execute and deliver to Coast such assignments or other instruments as
may be required by Coast in order to enable Coast to enforce any and all such
claims and to collect any and all dividends or other payments or disbursements
which may be made at any time on account of all and any of the Subordinated
Amounts. Subordinating Creditor shall endorse all notes and other written
evidence of the Subordinated Amounts with a statement that they are subordinated
to the Coast Debt pursuant to the terms of this agreement, in such form as Coast
shall require, and Subordinating Creditor will exhibit the originals of such
notes and other written evidence of the Subordinated Amounts to Coast so that
Coast can confirm that such endorsement has been made, but this Subordination
Agreement shall be fully effective, even if no such endorsement is made.

  2. Modifications to Coast Debt; Waivers. Until Coast have received payment in
full of all Coast Debt, the Subordinating Creditor agrees that, in addition to
any other rights that Coast may have at law or in equity, Coast may at any time,
and from time to time, without the Subordinating Creditor' consent and without
notice to the Subordinating Creditor, renew, extend or increase any of the Coast
Debt or that of any other person at any time directly or indirectly liable for
the payment of any Coast Debt, accept partial payments of the Coast Debt,
settle, release (by operation of law or otherwise), compound, compromise,
collect or liquidate any of the Coast Debt, make loans or advances to the
Borrower secured in whole or in part by the any present or future assets
securing any or all of the Coast Debt (the "Collateral") or refrain from making
any loans or advances to the Borrower, change, waive, alter or vary the interest
charge on, or any other terms or provisions of the Coast Debt or any present or
future instrument, document or agreement between Coast and the Borrower,
release, exchange, fail to perfect, delay the perfection of, fail to resort to,
or realize upon any Collateral, and take any other action or omit to take any
other action with respect to the Coast Debt or the Collateral as Coast deems
necessary or advisable in Coast's sole discretion. Subordinating Creditor waives
any right to require Coast to marshal any assets in favor of the Subordinating
Creditor or against or in payment of any or all of the Coast Debt. Subordinating
Creditor further waives any defense arising by reason of any claim or defense
based upon an election of remedies by Coast which in any manner impairs,
affects, reduces, releases, destroys and/or extinguishes the Subordinating
Creditor' subrogation rights, rights to proceed against the Borrower for
reimbursement, and/or any other rights of the Subordinating Creditor. In the
event of any financing of the Borrower by Coast during any bankruptcy,
arrangement, or reorganization of the Borrower, the Subordinating Creditor
agrees that the term "Coast Debt" shall include without limitation all
indebtedness, liabilities and obligations incurred in any such proceeding, and
the Subordinated Amounts shall continue to remain subordinate to the Coast Debt,
and the Subordinating Creditor agrees to take such actions and execute such
documents in such proceedings as may be required in order to continue such
subordination.

  3. Default. The Subordinating Creditor shall promptly give Coast written
notice of any default or event of default under any document, instrument or
agreement evidencing, securing or relating to any of the Subordinated Amounts,
and, until the Coast Debt has been paid and performed in full, the Subordinating
Creditor shall not exercise any rights or remedies with respect to, the
Subordinated Amounts, judicially or non-judicially, or attempt to do any of the
foregoing.

  4. No Commitment. It is understood and agreed that this Agreement shall in no
way be construed as a commitment or agreement by Coast to continue financing
arrangements with the Borrower and that Coast may terminate such arrangements at
any time, in accordance with Coast's agreements with the Borrower.

  5. No Contest. Subordinating Creditor agrees not to contest the validity,
perfection, priority or enforceability of Coast' security interest in the
Collateral or the Coast Debt.

  6. Financial Condition of Borrower. The Subordinating Creditor is presently
informed of the financial condition of the Borrower and of all other
circumstances which a diligent inquiry would reveal and which bear upon the risk
of non-payment of the Coast Debt and the Subordinated Amounts. The Subordinating
Creditor covenants that it will continue to keep itself informed as to the
Borrower's financial condition and all other circumstances which bear upon the
risk of non-payment of the

                Loan and Security Agreement
            --------------------------------------------------------------------

Coast Debt and the Subordinated Amounts. The Subordinating Creditor waives any
right to require Coast to disclose to it any information which Coast may now or
hereafter acquire concerning the Borrower.

  7. Revivor. If, after payment of the Coast Debt, the Borrower thereafter
becomes liable to Coast on account of the Coast Debt, as a result of any payment
made on the Coast Debt for any reason being returned by Coast or being reversed,
set aside, or recovered by the Borrower or any trustee or assignee for the
Borrower, this Agreement shall thereupon in all respects become effective with
respect to such subsequent or reinstated Coast Debt, without the necessity of
any further act or agreement between Coast and the Subordinating Creditor.

  8. General. The Subordinating Creditor agrees, upon Coast's request, to
execute all such documents and instruments and take all such actions as Coast
shall deem necessary or advisable in order to carry out the purposes of this
Agreement. The word "indebtedness" is used in this agreement in its most
comprehensive sense and includes without limitation any and all present and
future loans, advances, credit, debts, obligations, liabilities,
representations, warranties, and guarantees, of any kind and nature, absolute or
contingent, liquidated or unliquidated, and individual or joint. Subordinating
Creditor represents and warrants that it has not heretofore transferred or
assigned the Subordinated Amounts, and that it will not do so without prior
written notice to Coast and without making such transfer or assignment expressly
subject to this Agreement. This Agreement is solely for the benefit of Coast and
Coast's successors and assigns, and neither the Borrower nor any other person
shall have any right, benefit, priority or interest under, or because of the
existence of, this Agreement. All of Coast's rights and remedies hereunder and
under applicable law are cumulative and not exclusive. This Agreement sets forth
in full the terms of agreement between the parties with respect to the subject
matter hereof, and may not be modified or amended, nor may any rights hereunder
be waived, except in a writing signed by Coast and the Subordinating Creditor.
The Subordinating Creditor agrees to reimburse Coast, upon demand, for all costs
and expenses (including reasonable attorneys' fees) incurred by Coast in
enforcing this Agreement against Subordinating Creditor, whether or not suit be
brought. In the event of any litigation between the parties based upon or
arising out of this Agreement, the prevailing party shall be entitled to recover
all of its costs and expenses (including without limitation attorneys fees) from
the non-prevailing party. This Agreement shall be construed in accordance with,
and governed by, the laws of the State of California. As a material part of the
consideration to the parties for entering into this Agreement, each party (i)

to the benefit of Coast and Coast's successors and assigns.

                Loan and Security Agreement
            --------------------------------------------------------------------

to induce Coast to extend or continue to extend financing to the Borrower (but
without obligation on Coast's part to do so), the Subordinating Creditor hereby
agrees as follows:

1. Subordination of Debt and Capital Subordinating Creditor hereby subordinates
payment by the Borrower of any and all indebtedness, liabilities, guarantees and
other obligations of the Borrower to Subordinating Creditor and return of
Capital or Distributions now existing or hereafter arising (collectively, the
"Subordinated Amounts"), to the payment to Coast, in full in cash, of all
indebtedness, liabilities, guarantees and other obligations of the Borrower to
Coast, now existing or hereafter arising (including without limitation any
interest, charges and other sums accruing after the filing of a petition by or
against Borrower under the Bankruptcy Code) (the "Coast Debt").

      Subordinating Creditor represents and warrants that it has not transferred
or assigned the Subordinated Amounts or given any other subordination agreement
in respect thereof, and that it will not do so without prior written notice to
Coast and without making such transfer or assignment or subordination expressly
subject to this Agreement. Subordinating Creditor agrees not to ask for, demand,
sue for, take or receive all or any part of the Subordinated Amounts nor any
security therefor unless and until all of the Coast Debt has been paid and
performed in full, in cash; provided that, so long as no Event of Default and no
event which, with notice or passage of time or both, would constitute an Event
of Default under any present or future document, instrument or agreement
evidencing, securing or relating to the Coast Debt, both before and after giving
effect to the following payments, Subordinated Creditor may accept payment of
the following amounts on the Subordinated Amounts: Subordinating Creditor may
accept dividends declared by Borrower and repayment of all or part of the
Subordinated Amounts provided (a) such payments constitute ordinary course of
business transactions, (b) such payments would not constitute an event of
default and no event which, with notice or passage of time or both, would
constitute an event of default under any present or future document, instrument
or agreement between Borrower, Subordinating Creditor or any affiliate, on the
one hand and a party other than Coast on the other hand, (c) all such payments
are reported to Coast on a monthly basis, or more frequently if requested by
Coast, and (d) Coast has not given notice to Subordinating Creditor that Coast
has revoked the authorization of Subordinating Creditor to accept such dividends
or repayments of the Subordinated Amounts, which revocation may be made by Coast
if Coast in good faith believes that revocation is or may be necessary to avoid
or reduce the risk of a material adverse change or impairment of Coast's rights
or financial interests. Coast may further limit or condition dividends or
repayments of the Subordinated Amounts upon such terms as Coast, in its sole
discretion, deems appropriate, including, but not limited to, imposing dollar
limits and requiring advance notice to Coast of proposed dividends and
repayments in amounts which Coast, in its sole discretion, deems material.

Subordinating Creditor further agrees that upon any distribution of the assets
or readjustment of the indebtedness of the Borrower whether by reason of
liquidation, composition, bankruptcy, arrangement, receivership, assignment for
the benefit of creditors or any other action or proceeding involving the
readjustment of all or any of the Subordinated Amounts, or the application of
the assets of the Borrower to the payment or liquidation thereof, Coast shall be
entitled to receive payment in full in cash of all of the Coast Debt prior to
the payment of all or any part of the Subordinated Amounts, and in order to
enable Coast to enforce its rights hereunder in any such action or proceeding,
Coast is hereby irrevocably authorized and empowered in its discretion (but
without any obligation on its part) to make and present for and on behalf of
Subordinating Creditor such proofs of claim and proofs of interest against the
Borrower on account of the Subordinated Amounts as Coast may deem expedient or
proper and to vote such proofs of claim and proofs of interest in any such
proceeding and to receive and collect any and all dividends or other payments or
disbursements made thereon in whatever form the same may be paid or issued and
to apply same on account of the Coast Debt. Subordinating Creditor further
agrees to execute and deliver to Coast such assignments or other instruments as
may be required by Coast in order to enable Coast to enforce any and all such
claims and to collect any and all dividends or other payments or disbursements
which may be made at any time on account of all and any of the Subordinated
Amounts. Subordinating Creditor shall endorse all notes and other written
evidence of the Subordinated Amounts with a statement that they are subordinated
to the Coast Debt pursuant to the terms of this agreement, in such form as Coast
shall require, and Subordinating Creditor will exhibit the originals of such
notes and other written evidence of the Subordinated Amounts to Coast so that
Coast can confirm that such endorsement has been made, but this Subordination
Agreement shall be fully effective, even if no such endorsement is made.

  2. Modifications to Coast Debt; Waivers. Until Coast have received payment in
full of all Coast Debt, the Subordinating Creditor agrees that, in addition to
any other rights that Coast may have at law or in equity, Coast may at any time,
and from time to time, without the Subordinating Creditor' consent and without
notice to the Subordinating Creditor, renew, extend or increase any of the Coast
Debt or that of any other person at any time directly or indirectly liable for
the payment of any Coast Debt, accept partial payments of the Coast Debt,
settle, release (by operation of law or otherwise),

                Loan and Security Agreement
            --------------------------------------------------------------------

compound, compromise, collect or liquidate any of the Coast Debt, make loans or
advances to the Borrower secured in whole or in part by the any present or
future assets securing any or all of the Coast Debt (the "Collateral") or
refrain from making any loans or advances to the Borrower, change, waive, alter
or vary the interest charge on, or any other terms or provisions of the Coast
Debt or any present or future instrument, document or agreement between Coast
and the Borrower, release, exchange, fail to perfect, delay the perfection of,
fail to resort to, or realize upon any Collateral, and take any other action or
omit to take any other action with respect to the Coast Debt or the Collateral
as Coast deems necessary or advisable in Coast's sole discretion. Subordinating
Creditor waives any right to require Coast to marshal any assets in favor of the
Subordinating Creditor or against or in payment of any or all of the Coast Debt.
Subordinating Creditor further waives any defense arising by reason of any claim
or defense based upon an election of remedies by Coast which in any manner
impairs, affects, reduces, releases, destroys and/or extinguishes the
Subordinating Creditor' subrogation rights, rights to proceed against the
Borrower for reimbursement, and/or any other rights of the Subordinating
Creditor. In the event of any financing of the Borrower by Coast during any
bankruptcy, arrangement, or reorganization of the Borrower, the Subordinating
Creditor agrees that the term "Coast Debt" shall include without limitation all
indebtedness, liabilities and obligations incurred in any such proceeding, and
the Subordinated Amounts shall continue to remain subordinate to the Coast Debt,
and the Subordinating Creditor agrees to take such actions and execute such
documents in such proceedings as may be required in order to continue such
subordination.

  3. Default. The Subordinating Creditor shall promptly give Coast written
notice of any default or event of default under any document, instrument or
agreement evidencing, securing or relating to any of the Subordinated Amounts,
and, until the Coast Debt has been paid and performed in full, the Subordinating
Creditor shall not exercise any rights or remedies with respect to, the
Subordinated Amounts, judicially or non-judicially, or attempt to do any of the
foregoing.

  4. No Commitment. It is understood and agreed that this Agreement shall in no
way be construed as a commitment or agreement by Coast to continue financing
arrangements with the Borrower and that Coast may terminate such arrangements at
any time, in accordance with Coast's agreements with the Borrower.

  5. No Contest. Subordinating Creditor agrees not to contest the validity,
perfection, priority or enforceability of Coast' security interest in the
Collateral or the Coast Debt.

  6. Financial Condition of Borrower. The Subordinating Creditor is presently
informed of the financial condition of the Borrower and of all other
circumstances which a diligent inquiry would reveal and which bear upon the risk
of non-payment of the Coast Debt and the Subordinated Amounts. The Subordinating
Creditor covenants that it will continue to keep itself informed as to the
Borrower's financial condition and all other circumstances which bear upon the
risk of non-payment of the Coast Debt and the Subordinated Amounts. The
Subordinating Creditor waives any right to require Coast to disclose to it any
information which Coast may now or hereafter acquire concerning the Borrower.

  7. Revivor. If, after payment of the Coast Debt, the Borrower thereafter
becomes liable to Coast on account of the Coast Debt, as a result of any payment
made on the Coast Debt for any reason being returned by Coast or being reversed,
set aside, or recovered by the Borrower or any trustee or assignee for the
Borrower, this Agreement shall thereupon in all respects become effective with
respect to such subsequent or reinstated Coast Debt, without the necessity of
any further act or agreement between Coast and the Subordinating Creditor.

  8. General. The Subordinating Creditor agrees, upon Coast's request, to
execute all such documents and instruments and take all such actions as Coast
shall deem necessary or advisable in order to carry out the purposes of this
Agreement. The word "indebtedness" is used in this agreement in its most
comprehensive sense and includes without limitation any and all present and
future loans, advances, credit, debts, obligations, liabilities,
representations, warranties, and guarantees, of any kind and nature, absolute or
contingent, liquidated or unliquidated, and individual or joint. Subordinating
Creditor represents and warrants that it has not heretofore transferred or
assigned the Subordinated Amounts, and that it will not do so without prior
written notice to Coast and without making such transfer or assignment expressly
subject to this Agreement. This Agreement is solely for the benefit of Coast and
Coast's successors and assigns, and neither the Borrower nor any other person
shall have any right, benefit, priority or interest under, or because of the
existence of, this Agreement. All of Coast's rights and remedies hereunder and
under applicable law are cumulative and not exclusive. This Agreement sets forth
in full the terms of agreement between the parties with respect to the subject
matter hereof, and may not be modified or amended, nor may any rights hereunder
be waived, except in a writing signed by Coast and the Subordinating Creditor.
The Subordinating Creditor agrees to reimburse Coast, upon demand, for all costs
and expenses (including reasonable attorneys' fees) incurred by Coast in
enforcing this Agreement against Subordinating Creditor, whether or not suit be
brought. In the event of any litigation between the parties based upon or
arising out of this Agreement, the prevailing party shall be entitled

                Loan and Security Agreement
            --------------------------------------------------------------------

to recover all of its costs and expenses (including without limitation attorneys
fees) from the non-prevailing party. This Agreement shall be construed in
accordance with, and governed by, the laws of the State of California. As a
material part of the consideration to the parties for entering into this
Agreement, each party (i) agrees that all actions and proceedings based upon,
arising out of or relating in any way directly or indirectly to, this Agreement
shall be litigated exclusively in courts located within Los Angeles County,
California, (ii) consents to the jurisdiction of any such court and consents to
the service of process in any such action or proceeding by personal delivery,
first-class mail, or any other method permitted by law, and (iii) waives any and
all rights to transfer or change the venue of any such action or proceeding to
any court located outside Los Angeles County, California. This Agreement shall
be binding upon the Subordinating Creditor and its successors and assigns and
shall inure to the benefit of Coast and Coast's successors and assigns.

  9. Mutual Waiver of Jury Trial. Subordinating Creditor and Coast each hereby
waive the right to trial by jury in any action or proceeding based upon, arising
out of, or in any way relating to: (i) this Agreement; or (ii) any other present
or future instrument or agreement between Subordinating Creditor and Coast; or
(iii) any conduct, acts or omissions of Subordinating Creditor or Coast or any
of their directors, officers, employees, agents, attorneys or any other persons
affiliated with Subordinating Creditor or Coast; in each of the foregoing cases,
whether sounding in contract or tort or otherwise.

1. Subordination of Debt and Capital Subordinating Creditor hereby subordinates
payment by the Borrower of any and all indebtedness, liabilities, guarantees and
other obligations of the Borrower to Subordinating Creditor and return of
Capital or Distributions now existing or hereafter arising (collectively, the

indebtedness, liabilities, guarantees and other obligations of the Borrower to

      Subordinating Creditor represents and warrants that it has not transferred
or assigned the Subordinated Amounts or given any other subordination agreement
in respect thereof, and that it will not do so without prior written notice to
Coast and without making such transfer or assignment or subordination expressly
subject to this Agreement. Subordinating Creditor agrees not to ask for, demand,
sue for, take or receive all or any part of the Subordinated Amounts nor any
security therefor unless and until all of the Coast Debt has been paid and
performed in full, in cash; provided that, so long as no Event of Default and no
event which, with notice or passage of time or both, would constitute an Event

evidencing, securing or relating to the Coast Debt, both before and after giving
effect to the following payments, Subordinated Creditor may accept payment of
the following amounts on the Subordinated Amounts: Subordinating Creditor may
accept dividends declared by Borrower and repayment of all or part of the
Subordinated Amounts provided (a) such payments constitute ordinary course of

Coast, and (d) Coast has not given notice to Subordinating Creditor that Coast
has revoked the authorization of Subordinating Creditor to accept such dividends
or repayments of the Subordinated Amounts, which revocation may be made by Coast
if Coast in good faith believes that revocation is or may be necessary to avoid
or reduce the risk of a material adverse change or impairment of Coast's rights
or financial interests. Coast may further limit or condition dividends or
repayments of the Subordinated Amounts upon such terms as Coast, in its sole
discretion, deems appropriate, including, but not limited to, imposing dollar
limits and requiring advance notice to Coast of proposed dividends and
repayments in amounts which Coast, in its sole discretion, deems material.

Subordinating Creditor further agrees that upon any distribution of the assets
or readjustment of the indebtedness of the Borrower whether by reason of
liquidation, composition, bankruptcy, arrangement, receivership, assignment for

the assets of the Borrower to the payment or liquidation thereof, Coast shall be
entitled to receive payment in full in cash of all of the Coast Debt prior to
the payment of all or any part of the Subordinated Amounts, and in order to
enable Coast to enforce its rights hereunder in any such action or proceeding,
Coast is hereby irrevocably authorized and empowered in its discretion (but
without any obligation on its part) to make and present for and on behalf of
Subordinating Creditor such proofs of claim and proofs of interest against the
Borrower on account of the Subordinated Amounts as Coast may deem expedient or
proper and to vote such proofs of claim and proofs of interest in any such
proceeding and to receive and collect any and all dividends or other payments or
disbursements made thereon in whatever form the same may be paid or issued and
to apply same on account of the Coast Debt. Subordinating Creditor further
agrees to execute and deliver to Coast such assignments or other instruments as
may be required by Coast in order to enable Coast to enforce any and all such
claims and to collect any and all dividends or other payments or disbursements
which may be made at any time on account of all and any of the Subordinated
Amounts. Subordinating Creditor shall endorse all notes and other written
evidence of the Subordinated Amounts with a statement that they are subordinated
to the Coast Debt pursuant to the terms of this agreement, in such form as Coast
shall require, and Subordinating Creditor will exhibit the originals of such
notes and other written evidence of the Subordinated Amounts to Coast so that
Coast can confirm that such endorsement has been made, but this Subordination
Agreement shall be fully effective, even if no such endorsement is made.

  2. Modifications to Coast Debt; Waivers. Until Coast have received payment in
full of all Coast Debt, the Subordinating Creditor agrees that, in addition to
any other rights that Coast may have at law or in equity, Coast may at any time,
and from time to time, without the Subordinating Creditor' consent and without
notice to the Subordinating Creditor, renew, extend or increase any of the Coast

agreement between Coast and the Borrower, release, exchange, fail to perfect,
delay the perfection of, fail to resort to, or realize upon any Collateral, and
take any other action or omit to take any other action with respect to the Coast
Debt or the Collateral as Coast deems necessary or advisable in Coast's sole
discretion. Subordinating Creditor waives any right to require Coast to marshal
any assets in favor of the Subordinating Creditor or against or in payment of
any or all of the Coast Debt. Subordinating Creditor further waives any defense
arising by reason of any claim or defense based upon an election of remedies by
Coast which in any manner impairs, affects, reduces, releases, destroys and/or
extinguishes the Subordinating Creditor' subrogation rights, rights to proceed
against the Borrower for reimbursement, and/or any other rights of the
Subordinating Creditor. In the event of any financing of the Borrower by Coast
during any bankruptcy, arrangement, or reorganization of the Borrower, the
Subordinating Creditor agrees that the term "Coast Debt" shall include without
limitation all indebtedness, liabilities and obligations incurred in any such
proceeding, and the Subordinated Amounts shall continue to remain subordinate to
the Coast Debt, and the Subordinating Creditor agrees to take such actions and
execute such documents in such proceedings as may be required in order to
continue such subordination.

  3. Default. The Subordinating Creditor shall promptly give Coast written
notice of any default or event of default under any document, instrument or

foregoing.

way be construed as a commitment or agreement by Coast to continue financing
arrangements with the Borrower and that Coast may terminate such arrangements at

execute all such documents and instruments and take all such actions as Coast
shall deem necessary or advisable in order to carry out the purposes of this
Agreement. The word "indebtedness" is used in this agreement in its most
comprehensive sense and includes without limitation any and all present and
future loans, advances, credit, debts, obligations, liabilities,
representations, warranties, and guarantees, of any kind and nature, absolute or
contingent, liquidated or unliquidated, and individual or joint. Subordinating
Creditor represents and warrants that it has not heretofore transferred or
assigned the Subordinated Amounts, and that it will not do so without prior
written notice to Coast and without making such transfer or assignment expressly
subject to this Agreement. This Agreement is solely for the benefit of Coast and
Coast's successors and assigns, and neither the Borrower nor any other person
shall have any right, benefit, priority or interest under, or because of the
existence of, this Agreement. All of Coast's rights and remedies hereunder and
under applicable law are cumulative and not exclusive. This Agreement sets forth
in full the terms of agreement between the parties with respect to the subject
matter hereof, and may not be modified or amended, nor may any rights hereunder
be waived, except in a writing signed by Coast and the Subordinating Creditor.
The Subordinating Creditor agrees to reimburse Coast, upon demand, for all costs
and expenses (including reasonable attorneys' fees) incurred by Coast in
enforcing this Agreement against Subordinating Creditor, whether or not suit be
brought. In the event of any litigation between the parties based upon or
arising out of this Agreement, the prevailing party shall be entitled to recover
all of its costs and expenses (including without limitation attorneys fees) from
the non-prevailing party. This

Agreement shall be construed in accordance with, and governed by, the laws of
the State of California. As a material part of the consideration to the parties
for entering into this Agreement, each party (i) agrees that all actions and
proceedings based upon, arising out of or relating in any way directly or
indirectly to, this Agreement shall be litigated exclusively in courts located
within Los Angeles County, California, (ii) consents to the jurisdiction of any
such court and consents to the service of process in any such action or
proceeding by personal delivery, first-class mail, or any other method permitted
by law, and (iii) waives any and all rights to transfer or change the venue of
any such action or proceeding to any court located outside Los Angeles County,
California. This Agreement shall be binding upon the Subordinating Creditor and
its successors and assigns and shall inure to the benefit of Coast and Coast's
successors and assigns.

  9. Mutual Waiver of Jury Trial. Subordinating Creditor and Coast each hereby
waive the right to trial by jury in any action or proceeding based upon, arising
out of, or in any way relating to: (i) this Agreement; or (ii) any other present
or future instrument or agreement between Subordinating Creditor and Coast; or
(iii) any conduct, acts or omissions of Subordinating Creditor or Coast or any

                               Security Agreement

Borrower:         Osicom Technologies, Inc., a Delaware corporation
                  (formerly known as Cray Communications, Inc.)
Address:          2800 28th Street, Suite 100
                  Santa Monica, California 90405

Date:             April 16, 1999

      This First Amendment (the "Amendment") to Loan and Security Agreement (the
"Loan Agreement") is entered into by and between Coast Business Credit(R), a
division of Southern Pacific Bank (fka Southern Pacific Thrift & Loan
Association) ("Coast"), and Osicom Technologies, Inc., a Delaware corporation,
formerly known as Cray Communications, Inc. ("Borrower"). The Loan Agreement and
Schedule, as modified by this Amendment, shall for all purposes be deemed to be,
and the same shall constitute an integral part of the Loan Agreement and
Schedule. (Definitions and certain terms used in this Amendment shall have the
meanings set forth in the Loan Agreement, the Schedule and all other documents
and agreements executed in connection therewith or in furtherance thereof).

      For good and valuable consideration, receipt of which is hereby
acknowledged, the Loan Agreement is hereby amended in the following respects:

SECTION 1 OF THE LOAN AGREEMENT (with respect to Loans) is supplemented as
follows:

      A subsection 1.1a is added which reads as follows:

    1.1a Letters of Credit. At the request of Borrower, Coast may, in its sole
discretion, arrange for the issuance of letters of credit for the account of
Borrower (collectively, "Letters of Credit"), by issuing guarantees to the
issuer of the letter of credit or by other means. All Letters of Credit shall be
in form and substance satisfactory to Coast in its sole discretion. The
aggregate face amount of all outstanding Letters of Credit from time to time
shall not exceed the amount shown on the Schedule (the "Letter of Credit
Sublimit"), and shall be reserved against Loans which would otherwise be
available hereunder. Borrower shall pay all bank charges for the issuance of
Letters of Credit. Any payment by Coast under or in connection with a Letter of
Credit shall constitute a Loan hereunder on the date such payment is made. Each
Letter of Credit shall have an expiration date no later than thirty (30) days
prior to the Maturity Date. Borrower hereby agrees to indemnify, save, and hold
Coast harmless from any loss, cost, expense, or liability, including, without
limitation, payments made by Coast, expenses, and reasonable attorneys' fees
incurred by Coast
<PAGE>

arising out of or in connection with any Letters of Credit. Borrower agrees to
be bound by the regulations and interpretations of the issuer of any Letters of
Credit guarantied by Coast and opened for Borrower's account or by Coast's
interpretations of any Letter of Credit issued by Coast for Borrower's account,
and Borrower understands and agrees that Coast shall not be liable for any
error, negligence, or mistake, whether of omission or commission, in following
Borrower's instructions or those contained in the Letters of Credit or any
modifications, amendments, or supplements thereto. Borrower understands that
Letters of Credit may require Coast to indemnify the issuing bank for certain
costs or liabilities arising out of claims by Borrower against such issuing
bank. Borrower hereby agrees to indemnify and hold Coast harmless with respect
to any loss, cost, expense, or liability incurred by Coast under any Letter of
Credit as a result of Coast's indemnification of any such issuing bank. The
provisions of this Agreement, as it pertains to Letters of Credit, and any other
present or future documents or agreements between Borrower and Coast relating to
Letters of Credit are cumulative.

      Except as expressly modified herein, all other terms and conditions of
Section 1 of the Loan Agreement, as previously modified or amended, remain
unchanged.

================================================================================

SECTION 1 OF THE SCHEDULE (with respect to the Credit Limit) is amended to read
as follows:

1.  CREDIT LIMIT

(Section 1.1):             Loans in a total amount at any time outstanding
                           not to exceed the lesser of a total of $7,000,000
                           (the "Maximum Dollar Amount"), or the sum of (a) and
                           (b) below:
                                (a) Loans (the "Receivable Loans") in an amount
                                    not to exceed 79% of the amount of
                                    Borrower's Eligible Receivables (as defined
                                    in Section 8 above) for the month of April,
                                    1999 and decreasing by 1% per month
                                    thereafter until such time as the advance
                                    rate reaches 75%, at which point the maximum
                                    advance rate shall remain at 75%. The
                                    advance rate on the Receivable Loans may be
                                    increased, in Coast's sole and absolute
                                    discretion, to an amount not to exceed 80%
                                    of Borrower's Eligible Receivables if Coast,
                                    in it sole and absolute discretion,
                                    determines that dilution of Receivables has
                                    been and is, in Coast's opinion, likely to
                                    continue at a rate that is 10% or less, plus

                                (b) Loans (the "Inventory Loans") in an amount
                                    not to exceed the lesser of:

<PAGE>

                                    (1) 30% of the value of Borrower's Eligible
                                    Inventory (as defined in Section 8 above),
                                    calculated at the lower of cost or market
                                    value and determined on a first-in,
                                    first-out basis, or
                                    (2) $1,500,000.00.

                                (c) A Term Loan (the "Equipment Loan") in the
                                    original principal amount of $478,000. The
                                    Equipment Loan will be repayable in 36 equal
                                    monthly installments of principal with the
                                    first principal installment due on May 31,
                                    1999 and continuing on the last day of each
                                    month thereafter. The Equipment Loan is
                                    evidenced by that certain Secured Term Note

Borrower:         Osicom Technologies, Inc., a Delaware corporation
                  (formerly known as Cray Communications, Inc.)
Address:          2800 28th Street, Suite 100
                  Santa Monica, California 90405

Date:             April 16, 1999


$478,000                                                 Los Angeles, California

FOR VALUE RECEIVED, the undersigned Borrower promises to pay to the order of
COAST BUSINESS CREDIT(R), a division of Southern Pacific Bank ("Coast"), at
12121 Wilshire Boulevard, Suite 1400, Los Angeles, California, or at any such
other address as the holder of this Secured Term Note (this "Note") shall
direct, the principal sum ("Principal") of Four Hundred Seventy Eight Thousand
Dollars ($478,000.00), plus interest and other charges as hereinafter provided.

      Principal hereunder shall be repaid in equal monthly installments of
Thirteen Thousand Two Hundred Severty Seven Dollars and Seventy Eight Cents
($13,277.78), with the first payment commencing on May 31, 1999 and continuing
on the last day of each month thereafter.

      The unpaid Principal balance together with accrued interest and other
charges shall be fully due and payable on the earlier of (i) the Maturity Date
as provided in Section 6.1 of the Loan and Security Agreement between Borrower
and Coast dated as of September 27, 1996, as amended by the 1st Amendment to
Loan and Security

Agreement of even date herewith (the "Loan Agreement"), (ii) the effective date
of termination as provided in Section 6.2 of the Loan Agreement (the Loan
Agreement and all documents and agreements relating thereto are collectively
referred to as the "Loan Documents") or (iii) February 1, 2002. The automatic
renewal provided in Section 6.1 of the Loan Agreement shall not be applicable to
modify the payment terms of the Principal hereunder.


                                      -1-
<PAGE>

      Interest shall accrue at a rate equal to the "Prime Rate" plus 2.5% per
annum, calculated on the basis of a 360-day year for the actual number of days
elapsed or such different interest rate as provided in the Loan Documents. The
interest rate shall be adjusted monthly as of the first day of each month, and
the interest to be charged for each month shall be based on the highest "Prime
Rate" in effect during said month. Interest shall be payable monthly, on the
last day of the month. "Prime Rate" means the actual "Reference Rate" or the
substitute therefor of Bank of America NT & SA whether or not that rate is the
lowest interest rate charged by said bank. If the Prime Rate, as defined, is
unavailable, "Prime Rate" shall mean the highest of the prime rates published in
the Wall Street Journal on the first business day of the month, as the base rate
on corporate loans at large U.S. money center commercial banks. Interest on this
Note shall be subject to adjustments as provided in Section 1.2 of the Schedule
to the Loan Agreement and Section 7.2 of the Loan Agreement.

      Principal of, and interest on, this Note shall be payable in lawful money
of the United States of America. If a payment hereunder becomes due and payable
on a Saturday, Sunday or legal holiday, the due date thereof shall be extended
to the next succeeding business day, and interest shall be payable thereon
during such extension.

      In the event Borrower fails to pay when due any payment of Principal or
interest on this Note, or if any default or event of default occurs under the
Loan Documents or any other present or future instrument, document, or agreement
between Borrower and Coast, Coast may, at its option, at any time, declare the
entire unpaid Principal balance of this Note plus all accrued interest and other
charges to be immediately due and payable, without notice or demand. The
acceptance of any installment of Principal or interest by Coast after the time
when it becomes due, as herein specified, shall not be held to establish a
custom, or to waive any rights of Coast to enforce payment when due of any
further installments or any other rights, nor shall any failure or delay to
exercise any rights be held to waive the same.

      Borrower agrees to pay an Early Termination Fee in the amount and when
provided in the Loan Agreement.

      All payments hereunder are to be applied first to costs and fees referred
to herein, second to the payment of accrued interest and the remaining balance
to Principal. Any Principal prepayment hereunder shall be applied against
Principal payments in the inverse order of maturity. Coast shall have the
continuing and exclusive right to apply or reverse and reapply any and all
payments hereunder in its sole discretion.

      Borrower agrees to pay all reasonable costs and expenses (including,
without limitation, attorneys' fees and costs) incurred by Coast in connection
with or related to this Note, or its enforcement, whether or not suit be
brought. Borrower hereby further waives presentment, demand for payment, notice
of dishonor, notice of nonpayment, protest, notice of protest, and any and all
other notices and demands in connection with the delivery, acceptance,
performance, default, or enforcement of this Note.


                                      -2-

      This Note is secured by the Collateral (as defined in the Loan Agreement)
and all other present and future security that may be provided by Borrower to
Coast. Nothing herein shall be deemed to limit any of the terms or provisions of
the Loan Documents, or any other present or future document, instrument or
agreement, between Borrower and Coast, and all of Coast's rights and remedies
hereunder and thereunder are cumulative.

      In the event any one or more of the provisions of this Note shall for any
reason be held to be invalid, illegal or unenforceable, the same shall not
affect any other provision of this Note and the remaining provisions of this
Note shall remain in full force and effect.

      No waiver or modification of any of the terms or provisions of this Note
shall be valid or binding unless set forth in a writing signed by a duly
authorized officer of Coast, and then only to the extent therein specifically
set forth.

      COAST AND BORROWER EACH HEREBY WAIVE THE RIGHT TO TRIAL BY JURY IN ANY
ACTION OR PROCEEDING BASED UPON, ARISING OUT OF, OR IN ANY WAY RELATING TO: (i)
THIS NOTE; OR (ii) ANY OTHER PRESENT OR FUTURE INSTRUMENT OR AGREEMENT BETWEEN
COAST AND BORROWER; OR (iii) ANY CONDUCT, ACTS OR OMISSIONS OF COAST OR BORROWER
OR ANY OF THEIR DIRECTORS, OFFICERS, EMPLOYEES, AGENTS, ATTORNEYS OR ANY OTHER
PERSONS AFFILIATED WITH COAST OR BORROWER.

      Except as otherwise provided in this Note, any dispute, controversy or
claim arising out of or relating to this Note shall be settled by arbitration
pursuant to the arbitration provisions set forth in the Loan Agreement.

      This Note is payable in, and shall be governed by the internal laws of,

      In consideration of the foregoing and the mutual promises and covenants
contained herein, the parties agree as follows:

1. SALES AND PURCHASES OF PRODUCTS

      1.1 Products. Subject to the terms and conditions of this Agreement,
Seller shall sell to Cisco the Products which Cisco may order from Seller.
Products shall be manufactured by Seller according to the Product Specifications
set forth in Exhibit B and the Cisco Quality Plan set forth in Exhibit C, as

trade secrets, know-how and other intellectual property related thereto
("Software").

      1.2 Product Enhancements and New Products. At the earliest date possible,
Seller shall notify Cisco of any new products or enhancements to or advanced
versions of existing Products. Upon written agreement between Cisco and Seller
as to pricing, such products shall be considered Products under this Agreement
and shall be purchased and sold under the terms and conditions of this
Agreement. Cisco may convert any or all of its future orders of Products to any
enhancements to or advancements of existing Products. If Seller implements any

      1.4 Project Managers. Each party has appointed a single project manager
("Project Manager"). The names, addresses and telephone and fax numbers of the
Project Managers are attached to this Agreement as Exhibit D. The Project
Managers shall act as liaisons between the parties with respect to their
respective performances of this Agreement and shall provide the parties from
time to time with the names and telephone numbers of additional specific contact
persons (e.g., to communicate specific information regarding support,
enhancements, etc.) when such direct contact is preferable. In the event that
either party appoints a new Project Manager, such party shall promptly notify
the other. Neither party's Project Manager has the authority to make any changes
to this Agreement.

damages if it fails to deliver items that were ordered and scheduled for
delivery in shorter than the standard lead-time and Seller was unable to deliver
on time or in accordance with the standard lead time.

      4.12 Allocation. Seller shall in any event use reasonable efforts to
maintain the ability to supply all Products that Cisco orders from Seller.
Seller agrees that, in the event of an allocation due to a Force Majeure event,
as specified in Section 16.1, Cisco's order(s), subject to normal lead-time
requirements, shall be filled according to an allocation plan no less favorable

thirty (30) days prior written notice to Cisco.

      6.2 Pre-Shipment Testing. Prior to delivery, Seller shall test all
Products in accordance with its standard testing procedures as set forth in
Exhibit H, and shall not ship Products which fail to meet the Specifications.
Seller agrees not to make any changes or modifications to any test process or
procedure without prior written notice to Cisco. At its option Cisco may, from
time to time, send its quality control personnel to Seller's factory to observe
the testing. In addition, Cisco may, from time to time, request modifications to
Seller's test procedure, where repetitive failure to meet Specifications has
been noted on shipped equipment in accordance with the Cisco Quality Plan.
Seller shall not unreasonably withhold modifications of this procedure.

      6.3 Engineering Change Approval. Seller shall not make any changes to any
production process, or the controlled process parameters or sources, types or
grade classifications of materials used, with respect to any Product without

working day after learning of any bug or other problem in a Product which may
result, or has already resulted in, an impact to the installed customer base of
such Product, and in any event no later than at the time an engineering request
is made, the discovering party shall notify the other of such problem. Seller
shall submit a request to make a change containing engineering data in support
of the request. Within ten (10) working days of receiving such request, Cisco
shall respond to Sellers request and shall either (i) approve the change; (ii)
disapprove the change; or (iii) extend the deadline for the approval or
disapproval period for an additional twenty (20) working days. If Cisco fails to
reject or request an extension within the ten (10) working days, or falls to
reject within the additional twenty (20) working days if extended, then the
requested engineering change shall be considered accepted by Cisco.
<PAGE>

      6.4 Cisco's Engineering Change Request. When an engineering change is
required by Cisco, Cisco shall provide Seller all applicable documentation,
specifications and the requested effective date of such engineering change.
Seller shall respond initially within ten (10) working days, advising Cisco as
to (i) implementation and the effective date of such change; (ii) associated
costs and effect to on-hand materials, on-order materials and work in process;
and (iii) the impact of the change upon existing Product pricing and shipment
schedules for the entire period for which purchase orders are outstanding.
Seller shall also identify any materials issue or process issue that modifies
the shipment schedule that was in effect immediately prior to the engineering
change. Where a requested change may create scrap costs, Seller agrees to stop
work in process and/or orders for materials within twenty-four (24) hours of
notification of such change by Cisco. Materials on-hand or on-order and work in
process which has become obsolete as a result of the engineering change shall be
treated in the same manner as termination of a Product as set forth herein.
Cisco shall issue requisite documentation and purchase order release changes
before Seller shall begin the change implementation.

7.    DOCUMENTATION AND TRADEMARKS

      7.1   Documentation. Seller shall deliver its standard commercial
            documentation as set forth in Exhibit 1.

            slogans listed on Exhibit J (the 'Trademarks") as updated by Seller
            and agreed to in writing by Cisco from time to time. Cisco shall use
            the Trademarks in accordance with Seller's Trademark usage
            guidelines specified in Exhibit J, and as mutually agreed to by the
            parties from time to time. If any of Seller's Trademarks are to used
            in conjunction with Cisco's or another party's trademarks, on or in
            relation to the Product, then Seller's Trademarks shall be presented
            legibly, but nevertheless separated from the other, so that each
            appears to be a trademark in its own right, distinct from the other
            mark.

be mutually agreed upon by the parties.

11.   INDEMNITY

      11.1 Indemnification by Seller. Seller shall defend, indemnify and hold
Cisco harmless from any and all damages, liabilities, costs and expenses

result of (i) any breach of this Agreement; (ii) any claim of product liability
in any way relating to the Product; (iii) any claim which alleges that any
Product provided to Cisco hereunder or the use or distribution thereof infringes
upon, misappropriates or violates any patents, copyrights, trademarks, or trade
secret rights or other proprietary rights, of persons, firms or entities who are
not parties to this Agreement. As a condition to such defense and
indemnification, Cisco will provide Seller with prompt written notice of the
claim and permit Seller to control the defense, settlement, adjustment or
compromise of any such claim. Cisco may employ counsel at its own expense to
assist it with respect to any such claim. Cisco shall have no authority to
settle any claim on behalf of Seller.

      11.2 Sellers Efforts. If the manufacture, service, import, support,

use, service, import, support, distribution, or sale of the Product without
infringement and in compliance with the Specifications. If Seller is unable to
achieve either of the foregoing within thirty (30) days after receipt of notice
thereof, Seller shall promptly refund to Cisco the invoiced purchase price, plus
all shipping, storage, and associated costs, of any Products returned freight
collect to Seller which Cisco or its customers are legally prohibited from
selling or using. Nothing in this paragraph shall limit any other remedy of
Cisco.

      11.3 Exceptions to Seller Indemnity. Seller shall have no obligation under
paragraphs 11.1 and 11.2 to the extent any claim of infringement or
misappropriation results from (i) use of a Product in combination with any other
products not intended by Seller; (ii) any alteration or modification of a
Product not provided or authorized by Seller; or (iii) use of the Product in a
way not intended by Seller or not provided for or described in the applicable
technical documentation.

      15.1 Designation. Cisco may assign all or a portion of its rights to
purchase the Products to Designated Third Parties. "Designated Third Party" for
a Product shall mean each company (including without limitation Cisco's
manufacturing subcontractors ("Cisco Subcontractors") and Cisco's trading
partners ("Trading Partners")) which Cisco notifies Seller in writing is
authorized to purchase that Product from Seller pursuant to the terms and
conditions of this Agreement. Cisco shall be entitled to withdraw each such
authorization by written notice to Seller, and upon such notice the applicable
company shall no longer be a "Designated Third Party" for that Product. If so
requested, Seller agrees to negotiate, in good faith, with
<PAGE>

any Trading Partner modifications to the terms and conditions of this Agreement
as applied to Product purchases by that Trading Partner.

      15.2 Application of Agreement to Designated Third Parties (Contract
Manufacturer). As provided above, a Designated Third Party may issue to Seller
purchase orders of its own against a purchase order issued by Cisco to such
Designated Third Party. Cisco shall be liable to pay only for Products ordered
by and invoiced directly to Cisco and shall not be liable to pay for any
Products ordered by the Designated Third Parties, except as otherwise agreed to
in writing by Cisco with respect to Cisco Subcontractors. All references in this
Agreement to purchases of, purchase orders for, or shipments of Products by or

of volume pricing or other terms or conditions dependent on volume, all
purchases of Products by Cisco and Cisco Subcontractors shall be aggregated for
the benefit of Cisco.

16.   MISCELLANEOUS

      16.1 Force Majeure. Neither party shall be liable to the other for delays
or failures in performance resulting from causes beyond the reasonable control
of that party, including, but not limited to, acts of God, labor disputes or
disturbances, material shortages or rationing, riots, acts of war, governmental
regulations, communication or utility failures, or casualties. In the event
Seller fails to deliver Product due to such causes, Cisco may either:

      (a) Terminate this Agreement or any part hereof as to Product(s) not
shipped; or

      (b) Suspend this Agreement in whole or in part for the duration of the
delaying cause, and at Cisco's option, buy the Product(s) elsewhere and deduct
from any commitment to Seller the quantity so purchased. Seller shall resume
performance under this Agreement immediately after the delaying cause ceases
and, at Cisco's option, extend the then current term period for a period
equivalent to the length of time the excused delay endured; or

      (c)   Exercise its Manufacturing Rights pursuant to this Agreement.

      16.2 Compliance with Laws. Seller warrants that in performance of work
under this Agreement it has complied with or shall comply with all applicable
federal, state, local laws and ordinances now or hereafter enacted including,
but not limited to OSHA, the Fair Labor Standards Act of 1938 (29 USC 201-219),
the 8Hour Law (40 USC 327-332), the Foreign Corrupt Practices Act (15 USC 78),
the Equal Opportunity and Affirmative Action Regulations, and laws restraining
the use of convict labor. Seller warrants that in performance of work under this
Agreement it has complied, in all material respects, with all laws, regulations,
statutes and ordinances of all governmental entities including local, state,
federal or international, now or hereafter enacted, which regulate any material
because it is radioactive, toxic, hazardous or otherwise a danger to health,
reproduction or the environment, including but not limited to the Comprehensive
Environmental Response Compensation and Liability Act of 1980, the Resource
Conservation Recovery Act, the Federal Water Pollution Control Act, the Clean
Air Act, the Montreal Protocol, the Toxic Substances Control Act and similar
laws, rules, statutes, treaties or orders and international understandings. In
addition, Seller shall secure and maintain adequate workmen's compensation
insurance in accordance with the laws of the state or states from which Seller
shall furnish the Product and/or services for Cisco. Upon Cisco's request,
Seller shall issue certificates certifying compliance with any of the
aforementioned laws or regulations as may be applicable to the Product and/or
services being furnished hereunder.

      16.3 Import and Export. Seller shall provide all information under its
control which is necessary or useful for Cisco to obtain any export or import
licenses required for Cisco to ship or receive Software, including, but not
limited to, certificates of origin, (NAFTA, etc.), manufacturer's affidavits,
Buy America qualification, and U.S. Federal Communications Commissions
identifier, if applicable. This information is to be provided within ten (10)
business days of Cisco's request. The parties agree to comply with all
applicable export laws and regulations of the United States.

      16.4 Relationship of Parties. The parties are independent contractors
under this Agreement and no other relationship is intended, including a
partnership, franchise, joint venture, agency, employer/employee, fiduciary,
master/servant relationship, or other special relationship. Neither party shall
act in a manner which expresses or implies a relationship other than that of
independent contractor, nor bind the other party.

      16.5 No Third Party Beneficiaries. Unless otherwise expressly provided, no
provisions of this Agreement are intended or shall be construed to confer upon
or give to any person or entity other than Cisco and Seller any rights, remedies
or other benefits under or by reason of this Agreement.

      16.6 Equitable Relief. Each party acknowledges that a breach by the other
party of any confidentiality or proprietary rights provision of this Agreement
may cause the non-breaching party irreparable damage, for which the award of
damages would not be adequate compensation. Consequently, the non-breaching
party may institute an action to enjoin the breaching party from any and all
acts in violation of those provisions, which remedy shall be cumulative and not
exclusive, and a party may seek entry of an injunction enjoining any breach or
threatened breach of those provisions, in addition to any other relief to which
the non-breaching party may be entitled at law or in equity.

      16.7 Attorneys Fees. In addition to any other relief awarded, the
prevailing party in any action arising out of this Agreement shall be entitled
to its reasonable attorneys' fees and costs.

      16.9 Assignment. Neither party may assign its rights or delegate its
obligations hereunder, either in whole or in part, whether by operation of law
or otherwise, without the prior written consent of the other. Any attempted
assignment or delegation without the other party's written consent will be void.

                                   Exhibit B-1
                        Product Specification for 2404-TX
                               September 25, 1998

4 Port, 64-bit Fast Ethernet Adapter for PCI

o     High Performance, 64 bit, 4 Port Fast Ethernet Adapter

o     Supports both 32 AND 64 bit PCI Buses

o     Supports IEEE 802.3u Auto Negotiation for 10OBase-TX and lOBase-T

o     Full Support for Full Duplex or Half Duplex operation

o     Short Form Factor PCI Card

o     Onboard Status LEDs

o     Uses Existing Category 5 Cabling

o     Full Plug-and-Play Support (No Jumpers)

The 2404-TX Fast Ethernet Adapter provides the equivalent of 4 separate
10/10OBase-TX adapters on one card, occupying only one slot on the PCI bus. The
addition of a 64-bit, PCI V2.1 compliant interface makes the card an excellent
choice for use in high-end server applications, while still being compatible
with current 32-bit bus architectures. The use of a 64-bit PCI to PCI Bridge,
with buffering, increases throughput on the PCI bus to the Ethernet controllers
giving your LAN even better performance.

Full Auto-Negotiation Capabilities

The 2404-TX adapter fully supports the IEEE standards for Auto-Negotiation and
flow control. The adapter will automatically determine the highest rate of
communication between other devices on the network. This includes full duplex,
100 Mbps operation giving a rate of 200 Mbps per port.

Using Existing CAT 5 Cabling

2404-TX adapters work with your existing Ethernet cabling (CAT 5 UTP), so you
don't have to re-cable your network to get the I OX performance available with
Fast Ethernet.

TEST PROCEDURE 2404 FAST-Ethernet                        Document #: 915-4945-01

1 INTRODUCTION

1.1 The purpose of this procedure is to insure the functional operation of the
2404 PCI Quad FAST-Ethernet card.

1.2 This procedure must be followed explicitly, step by step. Do not attempt to
make connections, apply power, or change options, until instructed to do so.
Failure to comply with these instructions could result in personal injury or
equipment damage.

2 REFERENCE DOCUMENTS

         UUT Schematic  320131-01-SCH ERC 03
         Top Bill of Material    402404-01 ERC 02

3 EQUIPMENT REQUIRED

1) IBM compatible PC with internal PCI bus and Monitor, Keyboard and Scanner
2) 2) Fast Ethernet RJ45 Loopback Plugs (4 per card)

4 INITIAL SETUP

      4.1 Install up to four (4) 2404 boards into the PCI slot(s)on the test
fixture starting with slot 0. See figure 1.

      4.2 Install the appropriate loopback plugs into each card.

5 POWER UP SEQUENCE

      5.1 Apply power to the PC and Monitor.

6 TEST SEQUENCE

      6.1 SROM Programming, Version: 2.0 must be performed before diagnostic
tests can be run.

      At the menu prompt:
      Scan the SRON2404 -p 2404 barcode on the test bed.
      Scan serial number barcodes on UUT cards starting with slot 0.
               **serial#Oserial#3.
      Press    Enter

               **Osicom Networking Division requires serial number data To be
               entered via a bar-code wand or pen for accuracy.

      6.2 Turn off power to the PC.

      6.3 Turn on the power to the PC. This will load the contents of the SROM
into the INTEL components.

      6.4 Verify all green link LEDs are on. (Lights closest to the main board)

6.5 At the menu type: 7 < cr >.

TEST PROCEDURE 2404 FAST-Ethernet                        Document #: 915-4945-01

            This will load the 2404 diagnostics test software. Verify that you
            are using the correct version of software. The version number is
            printed at the top of the screen at startup as well as above the
            result matrix.

      6.6   When prompted to type the number of 2404 cards inserted into the PCI
            slots, make sure the number given is the number of CARDS in the
            system, and NOT the number of ports. For example, if there are four
            2404 cards in the system then press '4', and DO NOT hit the return
            key after typing the number!

            Note: Be sure to watch the LEDs on the 2404 ports to ensure they all
            flicker during this test. The link LED lights are the closest to the
            motherboard. While the activity link lights are farthest from the
            motherboard.

      6.7 Diagnostic sub-tests will start to execute, indicated by intermittent
      progress messages.

      A 'FAILED!' appearing at the end of a stream of dots, indicates a failure.
      A passed test is indicated by 'PASSED'.

      After the number of selected passes have been completed, the 'press any
      key to continue ...' I prompt will appear.

      Press any key and a test matrix is generated and displayed. A test report
      is created in the file diag. out as well. This file will be overwritten on
      each run of the diagnostics, so if the test information needs to be kept,
      be sure to move the output file.

      Note: The 'MAC' addresses at the top of the screen must be checked for
      accuracy and that they all there. There should be 4 addresses per card and
      the addresses must be in sequence. (if 4 cards are being tested there must
      be 16 addresses)

      Failures are displayed by a IF[ being displayed in the appropriate box. A
      box corresponds to a single test ran on a single port. Any box that
      displays a 1-1 means a particular test, was not executed for that port,
      and any box that displays a IV' means the test passed on that particular
      port. See figure 2 for a sample result matrix with two ports being tested
      with all tests. When completed reviewing the test matrix, press any key to
      back to the command prompt.

      The diagnostics tests may be stopped at any time by pressing the 'Escape'
      key.

      6.8 Turn power off to the PC test bed.

      Remove loopback plugs.

      Remove tested cards from the test bed and apply a 'Tested by' label to the
      cards which have passed and move cards to the next operation.
