            A Revised Merger Proposal--Your Vote Is Very Important

  To the Stockholders of Stanford Telecommunications, Inc.:

     Due to the recent market volatility of Newbridge Networks
  Corporation's common stock price, we have entered into an amended and
  restated merger agreement with Newbridge. The amended agreement provides
  that, rather than receiving Newbridge common stock, you will receive
  $34.22 in cash for each share of Stanford Telecom stock you hold. Other
  than the change in the form of consideration you will receive, the terms
  of the revised merger agreement are substantially the same as those
  presented for your approval in our previous proxy statement dated October
  12, 1999. Upon the merger, Stanford Telecom will become a subsidiary of
  Newbridge. The merger agreement also provides for the sales to third
  parties of our government and contract manufacturing businesses.

     We cannot complete the merger or the sale of our government business
  assets without the approval of our stockholders. Even if you submitted a
  proxy in connection with our previous proxy statement dated October 12,
  1999, you will need to complete the enclosed proxy in order to vote on
  the merger and government business asset sale. Proxies submitted in
  connection with our previous proxy statement dated October 12, 1999 will
  not be counted toward approval of the merger and government business
  asset sale.

     We have scheduled a special meeting on Monday, December 13, 1999 at
  10:00 a.m., local time, at the Sunnyvale Hilton, 1250 Lakeside Drive,
  Sunnyvale, California 94086, to vote on these transactions. A proxy
  statement accompanies this letter and provides detailed information about
  the special meeting, the merger and the sale of the government business
  assets. We urge you to read the proxy statement carefully.

     Your board of directors unanimously recommends that you vote to
  approve the merger agreement and the sale of the government business
  assets. Please use this opportunity to take part in the affairs of
  Stanford Telecom by voting on these important matters. Whether or not you
  plan to attend the meeting, please complete, sign, date and return the
  accompanying proxy in the enclosed self-addressed stamped envelope.
  Returning the proxy will not deprive you of your right to attend the
  special meeting and vote in person. Your vote is very important.

                                         Sincerely,
                                         /s/ Dr. James J. Spilker, Jr.
                                         Dr. James J. Spilker, Jr.

To the Stockholders of Stanford Telecommunications, Inc.:

   We have agreed, subject to your approval, to merge Stanford Telecom with a
subsidiary of Newbridge Networks Corporation. We also have agreed with
Newbridge to sell our government and contract manufacturing businesses to third
parties. The sale of the government business assets also requires your

merger is completed, you will receive $34.22, in cash without interest, in
exchange for each share of Stanford Telecom common stock that you hold.

   We will hold a special meeting of stockholders on Monday, December 13, 1999,
at 10:00 a.m., local time, at the Sunnyvale Hilton, 1250 Lakeside Drive,
Sunnyvale, California 94086, for the following purposes:

  1. to approve the Agreement and Plan of Merger, dated as of June 22, 1999,
     as amended and restated as of November 10, 1999, between Stanford

     subsidiary of Newbridge;

  2. to approve the sale of the government business assets; and

  3. to transact any other business that is properly brought before the
     special meeting, or any adjournment or postponement of the special

                                PROXY STATEMENT

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

   Stanford Telecom and Newbridge have entered into an amended and restated
merger agreement. If the transactions contemplated by the merger agreement are
completed:

  .  Stanford Telecom will become a wholly owned subsidiary of Newbridge; and

  .  Stanford Telecom's government business will be sold to third parties.

   The merger agreement and the sale of the government business assets must be
approved by the Stanford Telecom stockholders. If the sale of the government
business assets is not approved, or if the sale of the government business
assets has not closed prior to the merger, the merger will be completed and
Newbridge will effect the sale of the government business assets after the
merger.

   A special meeting of Stanford Telecom stockholders to vote on the merger
agreement and the sale of the government business assets will be held as
follows:

                               December 13, 1999
                             10:00 a.m., local time
                                Sunnyvale Hilton
                              1250 Lakeside Drive
                          Sunnyvale, California 94086

   The merger agreement provides that you will receive $34.22 in cash in
exchange for each share of Stanford Telecom stock you hold. Based on the number
of shares of Stanford Telecom common stock outstanding on November 11, 1999,
the aggregate amount of cash consideration to be paid to Stanford Telecom
stockholders in the merger will be approximately $454.5 million.

   Please give all of the information contained in this proxy statement your

On November 10, 1999, Ferris, Baker Watts, Incorporated delivered an opinion

point of view. We have attached a copy of Ferris, Baker Watts' written opinion
dated as of November 10, 1999 to this proxy statement as Appendix D. The
Ferris, Baker Watts opinion sets forth the assumptions made, procedures
followed, matters considered, limitations on and scope of review by Ferris,

 .  we obtain or file all material consents, agreements, authorizations, orders
   or approvals of, or filings with, any government entity; and

 .  our respective representations and warranties in the merger agreement
   continue to be materially accurate.

Conditions to the obligations of Newbridge. In addition to the conditions
above, Newbridge is not obligated to complete the merger unless several
conditions are satisfied or (in some cases) waived, including the following:

 .  there are no material adverse changes in the business of Stanford Telecom,
   except as specifically permitted in the merger agreement;

   contract manufacturing businesses which provide for minimum after-tax
   proceeds to Stanford Telecom of $102 million;

Termination fee (page 31)

In connection with the termination of the merger agreement, under specific
circumstances Stanford Telecom would be required to pay Newbridge a termination
fee of $25 million. In addition, in connection with termination of the merger
agreement under other circumstances which do not require Stanford Telecom to
pay Newbridge the termination fee, Stanford Telecom may be required to pay
Newbridge's documented expenses in connection with the merger agreement.

Technology license option agreement (page 33)

In connection with the merger, Stanford Telecom has granted Newbridge an option
to acquire a perpetual, nonexclusive, fully paid license to Stanford Telecom
intellectual property necessary to make and distribute Stanford Telecom's
wireless broadband products. The option may be exercised at any time by
Newbridge after a change in control of Stanford Telecom for a purchase price of
$69 million.

Stock option agreement (page 34)

In connection with the merger, Stanford Telecom has granted Newbridge an option
to purchase a number of shares of Stanford Telecom common stock equal to 19.9%
of the outstanding shares of Stanford Telecom common stock. The option becomes
exercisable in specified circumstances that could result in termination of the
merger agreement. The option has an exercise price of $35 per share.

Sales of Stanford Telecom's assets (page 36)

As a condition to Newbridge's obligation to complete the merger, Stanford
Telecom is required to enter into binding agreements to sell its government and
contract manufacturing businesses for after-tax net cash proceeds of at least
$102 million. Stanford Telecom does not intend to sell the government business
assets if the merger with Newbridge is not approved by its stockholders.

Sale of government business assets. Stanford Telecom has entered into an
agreement with ITT Industries, Inc. to sell to ITT Industries the government
business assets for $191 million, subject to adjustment based on the net worth
of the government business on the closing date of the sale. The ITT Industries
agreement is described in this proxy statement beginning on page 39. The
agreement is subject to conditions. As a result, we cannot assure you that the
sale will be completed or that it will be completed at this price.

The transfer of Stanford Telecom's contracts with the government cannot become
effective without the government's recognition of the purchaser as successor in
interest to the contracts and entry into a novation agreement in accordance
with the provisions of the Federal Acquisition Regulation.

Sale of contract manufacturing business assets. On October 29, 1999, Stanford
Wireless Broadband, Inc., a wholly owned subsidiary of Stanford Telecom, sold
the contract manufacturing business to Dii Semiconductor, Inc. for
approximately $11 million.

Conditions to the sale of the Stanford Telecom government business assets (page

   under the U.S. antitrust laws has expired or been terminated;

   in the asset purchase agreement continue to be materially accurate.

Condition to obligations of ITT Industries. In addition to the conditions
above, ITT Industries will not be obligated to purchase the government

                                       4
<PAGE>

business assets unless Stanford Telecom has obtained each of the consents or
approvals listed in the asset purchase agreement.

Condition to obligations of Stanford Telecom. In addition to the conditions
above, Stanford Telecom will not be obligated to sell the government business
assets unless the merger agreement is (1) fully performed or (2) in full force
and effect and Stanford Telecom is not aware of any event that will prevent or
delay the merger.

Termination of the government business asset purchase agreement (page 44)

ITT Industries and Stanford Telecom can agree by mutual consent to terminate
the asset purchase agreement at any time before the closing of the sale of the
government business assets.

Either ITT Industries or Stanford Telecom can terminate the asset purchase
agreement under various circumstances, including if:

 .  the sale of the government business assets is not completed by March 31,
   2000;

 .  the U.S. government advises that it will not enter into a novation agreement
   in connection with the government contracts listed in the asset purchase
   agreement;

 .  the other party breaches any of its representations, warranties, covenants

 .  a court or other government entity prohibits the sale of the government
   business assets.

Regulatory approvals (pages 19 and 38)

of the government business assets until after we have furnished information and
materials to the Antitrust Division of the Department of Justice and the
Federal Trade Commission and a required waiting period has ended.

Newbridge and Stanford Telecom each filed the required notification and report
form relating to the merger, and the waiting period was terminated on August
16, 1999.

Stanford Telecom and ITT Industries each filed the required notification and
report form relating to the sale of the government business, and the waiting
period was terminated on October 14, 1999.

The merger is also subject to review by the Committee on Foreign Investment in
the United States (CFIUS) under the Exon-Florio Amendment, which provides for
national security reviews and investigations of foreign acquisitions of U.S.
companies. CFIUS notification is voluntary, but without CFIUS review the
President has the authority to block the transaction or require divestiture
after closing. Newbridge and Stanford Telecom filed a joint voluntary
notification of the transaction, and on November 1, 1999, the Department of the
Treasury notified Newbridge and Stanford Telecom that it would not commence an
investigation in connection with the merger.

Accounting treatment (pages 20 and 38)

The merger will be accounted for by Newbridge as a purchase in accordance with
Canadian and U.S. generally accepted accounting principles.

The sale of the government business assets will be accounted for by Stanford
Telecom as a sale of assets in accordance with U.S. generally accepted
accounting principles.

                                Sunnyvale Hilton
                              1250 Lakeside Drive
                          Sunnyvale, California 94086

Purpose

   The purpose of the special meeting is:

  .  to approve and adopt the Agreement and Plan of Merger, dated as of June
     22, 1999, as amended and restated as of November 10, 1999 between
     Stanford Telecom, Newbridge and Saturn Acquisition Corp., which will
     result in Stanford Telecom becoming a wholly owned subsidiary of
     Newbridge;

  .  to approve the sale of government business assets; and

  .  to transact any other business that is properly brought before the
     special meeting, or any adjournment or postponement of the special
     meeting.

Record Date

   The Stanford Telecom board of directors has fixed the close of business on
November 11, 1999, as the record date. Only holders of record of shares of
Stanford Telecom common stock on the record date are entitled to notice of and
to vote at the special meeting and any adjournments or postponements thereof.
On the record date, there were 13,280,750 shares of Stanford Telecom common
stock outstanding, which were held by approximately 1,664 stockholders of
record, as shown on the records of BankBoston, N.A., Stanford Telecom's
transfer agent for the common stock.

Quorum; Vote Required

   A majority of the outstanding shares of Stanford Telecom common stock
entitled to vote on the proposals must be represented, either in person or by
proxy, to constitute a quorum at the special meeting. The affirmative vote of
the holders of at least a majority of Stanford Telecom's common stock
outstanding and entitled to vote on the proposals is required to adopt the
merger agreement and to approve the merger and the sale of the government
business assets. Each stockholder is entitled to one vote for each share of
Stanford Telecom common stock held on the record date on each proposal.

   A proxy marked "ABSTAIN" will not be voted and will be counted only for the
purpose of determining whether a quorum is present. If an executed proxy is
returned by a broker holding shares in street name and the proxy indicates that
the broker does not have discretionary authority to vote on one or more of the
proposals, the shares will be considered present at the meeting for purposes of
determining the presence of a quorum, but will not be voted in favor of
adoption of the proposals. As a result, abstentions, failures to vote and
broker non-votes will have the same effect as a vote against each of the
proposals.

   Six directors and executive officers of Stanford Telecom are parties to
voting agreements with Newbridge and have agreed to vote their shares of
Stanford Telecom common stock in favor of the adoption of the merger agreement
and the related transactions. As of the record date, these directors and
officers held approximately

                                       8
<PAGE>

2,585,515 shares of Stanford Telecom common stock which represent approximately
19.5% of the outstanding shares of Stanford Telecom common stock entitled to
vote on the proposals. See the discussion under "The Merger Agreement--Voting
Agreements" below.

Proxies

   All shares of Stanford Telecom common stock represented by properly executed
proxies received before or at the special meeting will, unless the proxies are
revoked, be voted in accordance with the instructions indicated on the proxies.
If no instructions are indicated on a properly executed returned proxy, the
shares will be voted "FOR" the merger and "FOR" the sale of the government
business assets.

   Stanford Telecom does not expect to present any matter not discussed in this
proxy statement for action at the special meeting. If any other matters,
including, consideration of a motion to adjourn or postpone the meeting for the
purpose of soliciting additional proxies or votes, are properly brought before
the special meeting, the persons named in the proxies will have discretion to
vote on those matters in accordance with their best judgment, unless authority
to do so is specifically withheld in the proxy.

Revocation of Proxies

   You may revoke your proxy at any time before it is voted by:

  .  providing written notice to the Secretary of Stanford Telecom at
     Stanford Telecommunications, Inc., 1221 Crossman Avenue, Sunnyvale,
     California 94089, Attention: Secretary (a notice of revocation must be
     signed and may be mailed or hand delivered to this address, or
     transmitted by facsimile to (408) 745-2410 before the vote is taken at
     the special meeting);

  .  delivering a subsequently dated and signed proxy; or

  .  appearing in person at the special meeting and voting by ballot.
     Attendance at the special meeting will not constitute revocation of a
     proxy.

Solicitation of Proxies and Expenses

   Newbridge and Stanford Telecom will share equally the costs of printing and
mailing this proxy statement and soliciting proxies. In addition to
solicitation by mail, proxies may be solicited in person by directors, officers
and employees of Stanford Telecom without additional compensation, and by
telephone, telegram, facsimile or similar method. Arrangements will be made
with brokerage houses and other custodians, nominees and fiduciaries to send
proxy material to beneficial owners, and Stanford Telecom will, upon request,
reimburse them for their reasonable expenses. Stanford Telecom has retained
Corporate Investor Communications, Inc. to aid in the solicitation of proxies
at a fee of approximately $5,500 plus expenses.

                           PROPOSAL NO. 1--THE MERGER

Background of the Merger

   Newbridge began the development of wireless broadband products in 1996 in
order to address a potentially large opportunity in the telecommunications
industry. The components provided by Stanford Telecom have become a strategic
part of Newbridge's solution for this market.

   In October 1997, Stanford Telecom and Newbridge began negotiations to enter
into agreements pursuant to which Stanford Telecom would perform certain
development work for Newbridge and Newbridge would acquire rights to distribute
Stanford Telecom wireless broadband products. In May 1998, Stanford Telecom and
Newbridge signed a reseller agreement. In June 1998, Stanford Telecom and
Newbridge signed a development agreement, which was made effective as of
December 23, 1997.

   During the summer of 1998, Mr. Conrad Lewis, Executive Vice President of
Newbridge, and Dr. Val Peline, President and CEO of Stanford Telecom, discussed
Newbridge's desire to make an equity investment in Stanford Wireless Broadband,
Inc., the subsidiary of Stanford Telecom which conducts the wireless broadband
business.

   In October 1998, Newbridge proposed terms for an investment in Stanford
Wireless Broadband, Inc., which were rejected by the Stanford Telecom board of
directors. Dr. Peline and Mr. Lewis thereafter agreed that, if Stanford Telecom
considered opportunities for a strategic combination in the future, Dr. Peline
would invite Newbridge to enter into discussions with Stanford Telecom.

   In January and February 1999, Mr. Bernard Herscovich, general manager of
Newbridge's wireless broadband business contacted Mr. George Hendry, President
of Stanford Wireless Broadband, Inc., about the ongoing development work and
requested that Newbridge obtain greater control of the development effort and
greater engineering attention and support. Mr. Hendry, after discussion with
Dr. Peline, informed Mr. Herscovich that this increased involvement would only
be available if Newbridge invested in Stanford Wireless Broadband, Inc.

   As a result of the growing acceptance of Newbridge's Microwave Multipoint
Distribution System ("MMDS") and Local Multipoint Distribution System ("LMDS")
in the marketplace, Newbridge became increasingly interested in acquiring
Stanford Telecom's wireless broadband business in order to secure access to
this strategic technology. On March 4, 1999, Mr. Lewis called Dr. Peline to
indicate a renewed interest in an investment in or acquisition of Stanford
Wireless Broadband, Inc.

   Newbridge began an initial due diligence review of the wireless broadband
business at Stanford Telecom's facilities in Sunnyvale, California on March 16,
1999.

   At meetings held on March 23, 1999 to March 25, 1999 at the offices of
Stanford Telecom in Sunnyvale, California, which were attended by Mr. Lewis and
Mr. Herscovich for Newbridge and Dr. Peline and Mr. Gary S. Wolf, Executive
Vice President of Stanford Telecom, Mr. Lewis presented various alternatives
relative to Newbridge's investment interest, including licensing the wireless
broadband technology, acquiring the assets of the wireless broadband business,
and acquiring all of Stanford Telecom and selling its government and contract
manufacturing businesses. Dr. Peline rejected the licensing alternative and
indicated that a sale of the wireless broadband business would create
prohibitive tax costs. After lengthy negotiations, Mr. Lewis offered to acquire
Stanford Telecom for stock at a price representing a premium to Stanford
Telecom stockholders in excess of 100% per share based on the Stanford Telecom
stock price at that time, with conditions relating to the amount of proceeds
that would need to be realized from the sale of the government and contract
manufacturing businesses. The meetings concluded on March 25, 1999 with the
signing of a non-binding letter of intent providing for Newbridge to acquire
Stanford Telecom. On that date, the closing price of the Standard Telecom
common stock was $14.00.

   At a meeting held on March 30, 1999, the Stanford Telecom board of directors
reviewed the letter of intent and authorized Stanford Telecom management to
negotiate a definitive agreement.


                                       10
<PAGE>

   On April 23, 1999, Dr. Peline and Mr. Lewis held a teleconference to discuss
revisions to the terms of the letter of intent proposed by Newbridge.

   On May 3, 1999, Mr. Lewis and Dr. Peline held a teleconference to further
discuss the terms of the transaction. It was agreed that Newbridge would
proceed with a comprehensive due diligence review of Stanford Telecom.

   On May 10, 1999, Mr. Lewis and Dr. Peline met in Sunnyvale, California to
negotiate revisions to the terms of the letter of intent.

   On May 18, 19 and 20, 1999, Dr. Peline, Mr. Wolf, Mr. Peter Nadeau, Vice
President and General Counsel of Newbridge, Mr. John Woronczuk, Assistant Vice
President, Business Development of Newbridge, and representatives of CIBC World
Markets, Inc., financial advisor to Newbridge, Heller Ehrman White & McAuliffe,
counsel to Newbridge, and Thelen Reid & Priest LLP, counsel to Stanford
Telecom, met to negotiate the terms of the transaction and finalize the new
letter of intent.

   On May 20, 1999, representatives of Newbridge and Stanford Telecom and their
legal, financial and other advisors met again in Sunnyvale, California to begin
the comprehensive due diligence review of Stanford Telecom's business. This due
diligence review continued through the execution of the definitive merger
agreement.

   On May 24, 1999, the Stanford Telecom board of directors approved the new
letter of intent, and it was signed by both parties. On that date, the closing
price of the Stanford Telecom common stock was $22.00.

   On June 1, 1999, the Newbridge board of directors discussed the proposal to
acquire Stanford Telecom and set up a special committee to review the merits of
the proposed transaction.

   On June 4, 1999, Stanford Telecom engaged Ferris, Baker Watts to analyze the
consideration offered to the Stanford Telecom stockholders in the proposed
transaction and to provide an opinion as to the fairness, from a financial
point of view, to the Stanford Telecom stockholders of the consideration to be
paid in connection with the proposed transaction.

   From June 7 through June 10, 1999, management of Stanford Telecom and
Newbridge, along with their legal and financial advisors, met to negotiate
drafts of the merger agreement, the technology license option agreement, the
stock option agreement and the voting agreement that had been proposed by
counsel to Newbridge.

   On June 16, 1999, the Stanford Telecom board of directors held a meeting to
discuss the proposed transaction and the status of negotiations between the
parties. Ferris, Baker Watts gave a presentation to the Stanford Telecom board
of directors. The board reviewed and discussed the terms of the proposed merger
agreement and the financial and other effects of the proposed merger on the
Stanford Telecom stockholders. Advisors from Thelen Reid & Priest LLP were also
present and participated in the discussions.

   On June 17, 1999, the Newbridge board of directors approved the merger
subject to certain conditions. Dr. Peline, Mr. Wolf and Mr. Jay Margulies of
Thelen Reid & Priest LLP met with Mr. Terrence Matthews, Chief Executive
Officer of Newbridge, Mr. Lewis and Mr. Nadeau in Denver, Colorado on June 18,
1999 to discuss the Newbridge board of directors' conditional approval.

   On June 20, 1999, the Newbridge board of directors removed the conditions to
its approval of the proposed transaction and approved the merger without
further conditions, except as contained in the merger agreement.

   On June 21 and 22, 1999, management of Stanford Telecom and Newbridge and
their legal and financial advisors met to finalize the terms of the definitive
merger agreement and ancillary agreements.

   At a meeting held on June 21, 1999, Ferris, Baker Watts delivered its
fairness opinion to the Stanford Telecom board of directors. After further
review and discussion of the terms of the proposed merger agreement, and the
financial and other effects of the proposed merger, the Stanford Telecom board
of directors unanimously approved the merger and authorized the officers of
Stanford Telecom to finalize and execute the merger agreement and ancillary
agreements.

                                       11
<PAGE>

   The definitive merger agreement and ancillary agreements were signed on
behalf of Newbridge, Stanford Telecom and Saturn Acquisition Corp. on June 22,
1999. On that date, the closing price of the Stanford Telecom common stock was
$26.44.

   At a meeting held at the request of Newbridge on November 8, 1999 in
Sunnyvale, California and attended by Dr. Peline, Mr. Wolf and Dr. Spilker of
Stanford Telecom and Mr. Lewis and Mr. Nadeau of Newbridge, along with their
legal and financial advisors, Newbridge proposed, because of the substantial
decline in its stock price since the announcement of the merger and the
dilutive effects of acquiring Stanford Telecom for stock, to change the
transaction to an all cash merger. After negotiations, the parties agreed to a
purchase price of $34.22 per share.

   On November 9, 1999, representatives of Newbridge and Stanford Telecom and
their legal and financial advisors met in Palo Alto, California to negotiate
revisions to the merger agreement.

   At a meeting held on November 10, 1999, the Newbridge board of directors
approved the amended and restated merger agreement.

   At a meeting of the Stanford Telecom board of directors held on November 10,
1999, Ferris, Baker Watts delivered a revised fairness opinion to the Stanford
Telecom board of directors in connection with the change of the transaction to
an all cash merger. After review of the terms of the amended and restated
merger agreement and the financial and other considerations of the new
transaction, the Stanford Telecom board of directors unanimously approved the
amended and restated merger agreement and authorized the officers of Stanford
Telecom to finalize and execute the amended and restated merger agreement.

   The amended and restated merger agreement was signed on behalf of Newbridge,
Stanford Telecom and Saturn Acquisition Corp. on November 10, 1999.

Stanford Telecom's Reasons for the Merger

   In reaching its determination to recommend approval and adoption of the
merger agreement and the merger, the Stanford Telecom board of directors
consulted with Stanford Telecom management, Ferris, Baker Watts, and Thelen
Reid & Priest LLP regarding the matters discussed above under "--Background of
the Merger." Among the factors discussed by the Stanford Telecom board of
directors and its advisors as benefits of the proposed merger were:

  .  the structure of the merger as a cash-for-stock transaction, which will
     enable Stanford Telecom's stockholders to receive $34.22 in cash for
     each share of Stanford Telecom stock they hold, thereby not subjecting
     the stockholders to the risks of receiving or holding Newbridge's
     currently volatile stock;

  .  the premium included in the purchase price over the then current stock
     price and over the values determined by the valuation analyses performed
     by Ferris, Baker Watts;

  .  the terms under which Stanford Telecom can consider alternative
     acquisition proposals by third parties; and

  .  the opinion of Ferris, Baker Watts that the consideration to be paid in
     the merger is fair, from a financial point of view, to Stanford
     Telecom's stockholders.

   The Stanford Telecom board of directors and its advisors also considered and
reviewed potentially negative factors relating to the merger, including the
following:

  .  the change from a tax-free transaction to a taxable transaction;

  .  the significant diversion of management and other resources in working
     toward completing the merger with Newbridge; and

  .  the potential value that alternative actions, such as remaining an
     independent company and continuing to grow the wireless broadband
     business internally and subsequently spinning-off Stanford Wireless
     Broadband, Inc., could provide to Stanford Telecom stockholders.

                                       12
<PAGE>

   In the course of deliberations, the Stanford Telecom board of directors
reviewed with Stanford Telecom management and outside advisors a number of
additional factors relevant to the merger, including:

  .  the terms of the merger agreement;

  .  the status of the sales of the government and contract manufacturing
     businesses;

  .  the status of Stanford Telecom's businesses and the current status of
     the telecommunications industry and applicable markets;

  .  the severance payments to be paid to certain Stanford Telecom employees
     who could be terminated after the merger; and

  .  the indemnification to be provided to present Stanford Telecom directors
     and officers.

   The foregoing discussion of the information and factors considered by the
Stanford Telecom board of directors is not intended to be exhaustive, but is
believed to include all material factors considered by the Stanford Telecom
board of directors. In light of the wide variety of information and factors
considered in connection with the proposed merger, the Stanford Telecom board
of directors did not consider it practicable to, nor did it attempt to,
quantify or otherwise assign relative weights to the specific factors it
considered in reaching its decision.

Recommendation of the Stanford Telecom Board of Directors

   After careful consideration, the Stanford Telecom board of directors
unanimously has determined the merger is fair to you and in your best interest,
and has declared that the merger is advisable. The Stanford Telecom board of
directors has approved the merger agreement and unanimously recommends your
adoption of the merger agreement and your approval of the merger.

   In considering the recommendation of the Stanford Telecom board of directors
with respect to the merger agreement, you should be aware that certain
directors and officers of Stanford Telecom have interests in the merger that
are different from, or are in addition to, yours. Please see the discussion
under "--Interests of Executive Officers and Directors of Stanford Telecom in
the Merger" below.

   The Stanford Telecom board of directors unanimously recommends that the
Stanford Telecom stockholders vote "for" approval of the merger agreement.

Opinion of Stanford Telecom's Financial Advisor

   Stanford Telecom retained Ferris, Baker Watts to investigate the proposed
consideration offered to Stanford Telecom stockholders and to provide an
opinion as to the fairness, from a financial point of view, to the Stanford
Telecom stockholders of the consideration to be paid in connection with the
merger agreement and the merger. Stanford Telecom requested Ferris, Baker Watts
to undertake the assignment because Ferris, Baker Watts is familiar with
telecommunications companies such as Stanford Telecom and has experience
advising companies with market capitalizations of similar size.

   On June 16, 1999, Ferris, Baker Watts delivered a presentation to the board
of directors of Stanford Telecom and subsequently delivered an opinion letter
dated June 21, 1999 that, based upon and subject to the considerations set
forth therein, as of that date, the consideration to be received by Stanford
Telecom stockholders pursuant to the merger agreement and the merger was fair
from a financial point of view. On November 10, 1999, Ferris, Baker Watts
delivered a revised opinion stating that the transaction, as described in the
amended and restated merger agreement, is fair to the stockholders from a
financial point of view. The November 10, 1999 opinion of Ferris, Baker Watts
was based upon economic, market and other conditions in effect as of the date
of the letter. No limitations were imposed by the board of directors of
Stanford Telecom upon Ferris, Baker Watts with respect to its investigation or
procedures followed by them in rendering the opinion. The opinion of Ferris,
Baker Watts, dated November 10, 1999, which sets forth assumptions made,
material reviewed, matters considered, and the limits of the review, is
attached as Appendix D and is incorporated by reference in this proxy
statement.

                                       13
<PAGE>

   The following is a summary of the opinion of Ferris, Baker Watts. Stanford
Telecom stockholders are urged to read the opinion in its entirety. Ferris,
Baker Watts has consented to the inclusion of its opinion in this proxy
statement and has reviewed the following summary of its opinion.

   In connection with its opinion, Ferris, Baker Watts reviewed, among other
things:

  .  the proposed merger agreement, as amended and restated as of November
     10, 1999;

  .  Stanford Telecom's annual reports on Form 10-K for the fiscal years
     ended March 31, 1998, 1997, 1996, and 1995;

  .  Stanford Telecom's annual report for the fiscal year ended March 31,
     1999;

  .  Stanford Telecom's quarterly reports on Form 10-Q for the periods ended
     June 30, 1999, December 31, 1998, September 30, 1998, June 30, 1998,
     December 31, 1997, September 30, 1997, June 30, 1997, December 31, 1996,
     September 30, 1996, and June 30, 1996; and

  .  projected financial results for fiscal years 2000 through 2002 provided
     by Stanford Telecom management.

   Ferris, Baker Watts also held discussions with management of Stanford
Telecom regarding its past and current business operations, financial condition
and future prospects. Ferris, Baker Watts considered the business relationship
Stanford Telecom had established with Newbridge and the fact that other systems
integrators had either already pursued mergers with suppliers or had proceeded
with internal development of their own technology. Ferris, Baker Watts reviewed
the reported price and trading activity of Stanford Telecom stock, compared
certain financial and stock market information concerning Stanford Telecom with
similar information for other comparable companies, the securities of which are
publicly traded, and performed other studies and analyses which Ferris, Baker
Watts deemed appropriate.

   Ferris, Baker Watts assumed and relied upon the accuracy and completeness of
all financial and other information reviewed for purposes of its opinion,
whether publicly available or provided to Ferris, Baker Watts by Stanford
Telecom, and did not independently verify the information or make an
independent evaluation or appraisal of assets or liabilities of Stanford
Telecom.

   The preparation of a fairness opinion involves determinations as appropriate
and relevant methods of financial analysis and, therefore, reference should be
made to the Ferris, Baker Watts opinion in its entirety and not to a summary
description. In performing its analysis, Ferris, Baker Watts made numerous
assumptions with respect to industry performance, business and economic
conditions and other matters, many of which are beyond the control of Stanford
Telecom. The analyses performed by Ferris, Baker Watts are not necessarily
indicative of future results and do not purport to be appraisals or to reflect
prices at which businesses actually may be sold.

   Ferris, Baker Watts considered several methods to evaluate the value of
Stanford Telecom, including:

  .  the discounted future free cash flow of Stanford Telecom;

  .  the earnings and book value multiple comparisons to publicly traded
     comparable companies;

  .  the merger and acquisition activity of companies engaged in similar
     businesses;

  .  the control premiums paid by acquirors over the market price of target
     companies prior to the takeover announcement date; and

  .  a breakup analysis.

Ferris, Baker Watts also considered the market value of Stanford Telecom's
shares as well as its trading history.

                                       14
<PAGE>

   The discounted future free cash flow analysis ascribes value only to the
cash flows that can ultimately be taken out of the business. These free cash
flows are then discounted to the present at the firm's weighted average cost of
capital. The weighted average cost of capital can be described as the average
price a company must pay to attract both debt and equity to properly capitalize
the firm's growth. It is these series of free cash flows that, when discounted
to the present and after subtracting claims by debtholders and others,
represents the economic value of a firm to its stockholders. This method of
valuation depends upon the accuracy of the financial projections. Ferris, Baker
Watts assumed that the projections were reasonably prepared by management of
Stanford Telecom on bases reflecting the best currently available estimates and
judgments as to the expected future financial performance. The offer value per
share represents a 25.3% to 34.7% premium to the intrinsic value of the shares
as determined by the discounted cash flow analysis.

   The earnings and book value multiple comparison analysis examines the
operating earnings, net income (both historical and projected), revenue and
book value multiples. Ferris, Baker Watts analyzed publicly available
historical financial information and projected financial results, including
multiples of price to expected earnings for the current fiscal year, price to
expected earnings for the next fiscal year, price to revenues and price to book
ratios. The comparable companies were found to have average multiples of 26.2x
price to current fiscal year expected earnings, 17.2x price to next fiscal year
expected earnings, 3.7x market value to book value and 2.9x market value to
revenue. Applying the multiples to Stanford Telecom's results yielded values
ranging from $23.35 to $33.53 per share, resulting in premiums from -6.2% to
44.8%.

   The comparable merger and acquisition transaction analysis examines publicly
available records for sale transactions in Stanford Telecom's industry. This
method of valuation is often difficult to perform due to the lack of publicly
available data on the target companies involved in the transactions. Ferris,
Baker Watts examined six transactions which disclosed target financial
information. The consideration offered in the merger is at a premium to the
value implied from this analysis.

   The control premium analysis examines stock prices of target companies prior
to takeover announcements and adjusts for takeover speculation. Market data for
the fourth quarter of 1998 indicated mean and median control premiums for
electrical components designers and manufacturers of 43.3% and 38.1%,
respectively, with a range of 11.1% to 113.1%. The consideration offered in the
merger is consistent with the values implied from the application of this
methodology.

   None of the companies utilized in the comparable company analysis,
comparable merger and acquisition transaction analysis, and the control premium
analysis for comparative purposes is, of course, identical to Stanford Telecom.
Accordingly, a complete analysis of the results of the foregoing calculations
cannot be limited to a quantitative review of the results and involves complex
considerations and judgments concerning differences in financial and operating
characteristics of the comparable companies and other factors that could affect
the value of the comparable companies as well as Stanford Telecom.

   The breakup analysis ascribes value based upon the value the components of
the business would receive in the event of a sale. Stanford Telecom had
received indications of interest from several parties interested in the
purchase of its government business. Stanford Telecom had also received an
indication of interest from a third party for its Telecom Component Products
division. The merger value represents a 29% to 38.7% premium to the value
derived from this analysis.

   From these analyses, Ferris, Baker Watts determined that the consideration
to be received by the Stanford Telecom stockholders was fair from a financial
point of view. In order for Ferris, Baker Watts to deliver its opinion dated
November 10, 1999, Ferris, Baker Watts updated the analysis described above and
concluded the consideration to be received by the Stanford Telecom stockholders
is fair from a financial point of view.

   Stanford Telecom is obligated to pay Ferris, Baker Watts a fee of $250,000
and to reimburse Ferris, Baker Watts for its out-of-pocket expenses in
connection with its opinion.

                                       15
<PAGE>

   The opinion of Ferris, Baker Watts relates only to whether the consideration
to be received by Stanford Telecom stockholders is fair from a financial point
of view and does not constitute a recommendation to any Stanford Telecom
stockholder as to how a stockholder should vote at the special meeting.

Newbridge's Reasons for the Merger

   The Newbridge board of directors approved of the merger, in part, due to its
belief that the acquisition of Stanford Telecom would constitute a significant
component of its strategy to penetrate the wireless broadband products market.

   Newbridge estimates that its wireless broadband network business will
generate $66 million (Cdn$100 million) in revenue in 1999, $198 million
(Cdn$300 million) in 2000 and $396 million (Cdn$600 million) in 2001. To date,
Newbridge has agreements with five LMDS licensees in the United States,
including Tri Corners Telecommunications, Gateway Telecom, South Central
Telecom, Home Telephone Inc. and Central Texas Communications. Newbridge is
also supplying LMDS networks to Korean Telecom and Canada's sole nationwide
spectrum holder, MaxLink Communications.

   Newbridge began the development of wireless broadband products in 1996 in
order to address the large potential market opportunity. Newbridge's products
incorporate components developed for Newbridge by Stanford Telecom, including a
wireless access system that Newbridge integrates with its Network Management
System and Switch. The wireless access system has become a strategic part of
the Newbridge solution.

   As a result of the growing acceptance of the Newbridge LMDS/MMDS solution,
Newbridge believes that the acquisition of Stanford Telecom is important to
securing access to this strategic technology. In addition, because of recent
acquisitions of MMDS spectrum holders by other telecommunications companies,
Newbridge believes such a time-to-market gain for its MMDS product line is
particularly timely.

   Some of the specific benefits to Newbridge of the merger include:

  .  a more cost-competitive product line to offer customers by virtue of
     increased vertical integration and manufacturing cost reductions, which
     will be achieved by moving the Stanford Telecom designs into Newbridge's
     much larger scale manufacturing operations;

  .  a more feature-rich product line to offer customers by combining two
     product management and engineering teams into a single team that will
     have a higher productivity from increased focus, better coordination and
     common and improved design tools; and

  .  an integrated LMDS/MMDS product line that Newbridge expects will be
     available to market sooner as a result of the incorporation of Stanford
     Telecom's early work in MMDS into Newbridge's LMDS platform.

Interests of Executive Officers and Directors of Stanford Telecom in the Merger

   In considering the recommendation of the Stanford Telecom board of
directors, you should be aware that the Stanford Telecom executive officers and
directors have interests in the merger that are different from, or are in
addition to, yours. These interests include:

  .  severance payments;

  .  accelerated vesting of stock options;

  .  contributions to the 401(k) plan accounts of the executive officers;

  .  payments under Standford Telecom's management incentive plan;

  .  an employment agreement for one Stanford Telecom executive officer; and

  .  continued indemnification for pre-merger actions.

                                       16

   Severance Payments. If Newbridge requests the resignation of a Stanford
Telecom executive officer as of the effective time of the merger or terminates
a Stanford Telecom executive officer within 90 days after the merger, Newbridge
will pay the executive officer one year's base salary as a one-time severance
payment.

   Accelerated Vesting of Stock Options. Unvested options granted under
Stanford Telecom's 1991 Stock Option Plan to employees, including executive
officers, who will not be employed by Stanford Telecom, Newbridge or a
purchaser of the government or contract manufacturing businesses following the
merger or who will be employed by a purchaser of the government or contract
manufacturing business assets but whose options will not be assumed (1) will
become fully vested and exercisable at the time the merger is completed and (2)
will be converted into stock options to purchase shares of Newbridge common
stock based on the exchange ratio. See "The Merger Agreement--Treatment of
Stock Options" and "The Merger Agreement--Employee Benefits." The following
table sets forth information regarding the unvested stock options held by the
executive officers as of the record date:

</TABLE>

   Contributions to 401(k) Plan Accounts. At the time the merger is completed,
Stanford Telecom employees, including executive officers, will receive
contributions to their 401(k) plan accounts. The amount of each contribution
will be a percentage of the employee's salary consistent with past practice,
prorated for the portion of the fiscal year completed as of the time of the
merger.

   Management Incentive Plan. At the time the merger is completed, the
executive officers will receive prorated payments under Stanford Telecom's
Management Incentive Plan if the performance goals of the plan have been met as
of the time of the merger.

   Employment Agreement. At effective time of the merger, John Ohlson,
currently the Chief Technical Officer of Stanford Telecom, is expected to enter
into an employment agreement with Newbridge. Dr. Ohlson is expected to serve as
Vice President, Satellite Personal Communications. During the term of the
employment agreement, Newbridge will pay Dr. Ohlson a base salary of
$205,836.80 per year. Dr. Ohlson will be entitled to participate in certain
Newbridge bonus and incentive plans and programs.

   Indemnification. Newbridge has, for a period of six years after the merger,
agreed in the merger agreement to:

  .  indemnify each present director and officer of Stanford Telecom and its
     subsidiaries against costs, damages, liabilities or expenses incurred in
     connection with claims arising out of or pertaining to the transactions
     contemplated by the merger agreement; and

  .  subject to some limitations, maintain directors' and officers' liability
     insurance for the benefit of Stanford Telecom directors and officers
     currently covered by Stanford Telecom's directors' and officers'
     liability insurance on terms comparable to Stanford Telecom's existing
     coverage.

Material United States Federal Income Tax Consequences

   General. The following discussion summarizes the material federal income tax
consequences of the merger. This discussion is based upon the Internal Revenue
Code, the regulations promulgated under the Code, Internal Revenue Service
rulings, and judicial and administrative rulings presently in effect, all of
which are subject to change, possibly retroactively. This discussion does not
address all aspects of federal income taxation that may be relevant to a
stockholder in light of the stockholder's particular circumstances or to those
Stanford Telecom stockholders subject to special rules, such as stockholders
who are not citizens or residents of the United States, financial institutions,
tax-exempt organizations, insurance companies, dealers in securities,
stockholders who acquired their Stanford Telecom stock pursuant to the exercise
of options or as compensation, or stockholders who hold their Stanford Telecom
stock as part of a straddle or similar transaction.

  Federal Income Tax Consequences to Stanford Telecom Stockholders

   For federal income tax purposes, the merger will be a taxable transaction
for Stanford Telecom stockholders and may be a taxable transaction for state,
local, foreign and other tax purposes. You will be treated as having sold your
Stanford Telecom common stock to Newbridge for cash. Accordingly:

  .  You will recognize taxable gain or loss measured by the difference
     between your tax basis in your Stanford Telecom common stock and the
     amount of cash that you receive in the merger or upon the exercise of
     your appraisal rights.

  .  If you have acquired separate blocks of Stanford Telecom common stock at
     different times or prices, you must calculate your gain or loss
     separately for each separate block.

  .  If you hold your Stanford Telecom common stock as a capital asset, your
     gain or loss will be capital gain or loss, and will be long term capital
     gain or loss if you have held your Stanford Telecom common stock for
     more than one year as of the closing date of the merger.

  .  Generally, you must net your capital gains and capital losses against
     each other in determining their tax consequences.

  .  Generally, if you are an individual, your tax rate on long-term capital
     gains is substantially lower than your tax rate on ordinary income. Your
     tax rate on short term capital gains will be the same as your tax rate
     on ordinary income.

  .  If you are an individual, you may deduct capital losses in a taxable
     year first against your capital gains and then against up to $3,000 of
     ordinary income.

  .  Individuals may carry their net capital losses that are not currently
     deductible forward indefinitely for deduction in future years, subject
     to the limitations applicable in the future years.

  .  Corporations generally may deduct capital losses only against capital
     gains. Corporations may carry their capital losses in excess of capital
     gains back to the three preceding taxable years and forward to the five
     succeeding taxable years for deduction against capital gains realized in
     those years.

  Federal Income Tax Consequences to Stanford Telecom and Newbridge

   The merger will be tax-free to Stanford Telecom and Newbridge. However, the
sales of the government and contract manufacturing business will be taxable
transactions to Stanford Telecom.

   The foregoing discussion is not intended to be a complete analysis or
description of all potential United States federal income tax consequences of
the merger. In addition, the discussion does not address tax consequences that
are dependant on your own circumstances. Moreover, the discussion does not
address any non-income tax consequences nor details any state, local or foreign
tax consequences of the merger. Accordingly, you are strongly urged to consult
with your tax advisor to determine the particular United States federal, state,
local or foreign income or other tax consequences of the merger to you.

Regulatory Approvals

   Consummation of the merger is conditioned upon the receipt of all
governmental authorizations, consents, orders or approvals, the filing of all
governmental declarations or filings and the expiration of waiting periods
imposed by any government entity, which if not obtained, filed or completed
would have a material adverse effect on Newbridge or Stanford Telecom. Although
Newbridge and Stanford Telecom have agreed to use all commercially reasonable
efforts to secure all the approvals, there can be no assurance regarding the
timing of the approvals or that the approvals will, in fact, be obtained. Set
forth below is a summary of the regulatory approvals needed in order to
complete the merger.

   Hart-Scott-Rodino. Under the Hart-Scott-Rodino Antitrust Improvements Act of
1976 and the rules promulgated thereunder by the Federal Trade Commission, the
merger may not be completed until notifications have been given and information
has been furnished to the FTC and the Antitrust Division of the United States
Department of Justice and specified waiting period requirements have been
satisfied. Newbridge and Stanford Telecom filed notification and report forms
relating to the merger under the Hart-Scott-Rodino Act with the FTC and the
Antitrust Division on August 3, 1999, and the waiting period was terminated on
August 16, 1999.

   At any time before or after consummation of the merger, the Antitrust
Division or the FTC could take action under the antitrust laws as it deems
necessary or desirable in the public interest, including seeking to enjoin the
consummation of the merger or seeking divestiture of substantial assets or
business of Newbridge or Stanford Telecom. At any time before or after the
consummation of the merger, and despite the termination of the Hart-Scott-
Rodino Act waiting period, any state could take action under its antitrust laws
as it deems necessary or desirable in the public interest. That action could
include seeking to enjoin the consummation of the merger or seeking divestiture
of substantial assets or businesses of Newbridge or Stanford Telecom. Private
parties may also seek to take legal action under antitrust laws.

   Based on information available to them, Newbridge and Stanford Telecom
believe that the merger can be effected in compliance with federal and state
antitrust laws. However, a challenge to the consummation of the merger on
antitrust grounds may be made and if a challenge is made, Newbridge and
Stanford Telecom may not prevail or may be required to accept conditions,
possibly including divestitures, in order to consummate the merger.

   Exon-Florio. The merger agreement provides for the parties to file a
voluntary notice under Section 721 of the Defense Production Act of 1950, as
amended by Section 5021 of the Omnibus Trade and Competitiveness Act of 1988
("Exon-Florio Amendment"). The Exon-Florio Amendment provides for national
security reviews and investigations by the Committee on Foreign Investment in
the United States (CFIUS) when a foreign company acquires control of a U.S.
company. CFIUS consists of representatives of various government agencies
including the Departments of State, Defense and Justice and is chaired by the
Treasury Department. On October 1, 1999, Newbridge and Stanford Telecom filed a
voluntary notice because Newbridge is a Canadian corporation and Stanford
Telecom has a substantial number of contracts with the U.S. government,
including classified contracts. On November 1, 1999, Newbridge and Stanford
Telecom received notification from CFIUS that it would not commence an
investigation in connection with the merger.

   CFIUS considers many factors in determining whether a proposed transaction
threatens to impair national security, including domestic production needed for
national defense requirements, the capability of domestic industries to meet
national defense requirements, and the potential effects on U.S. international
technological leadership in areas affecting national security.

   Department of Defense rules prohibit the performance of classified contracts
by companies that are subject to foreign ownership, control or influences
(FOCI) unless steps are taken to mitigate FOCI by such means as the
establishment of a proxy company or voting trust. If the sale of government
business assets is completed prior to the effective time of the merger,
Newbridge will not acquire ownership, control or influence over Stanford
Telecom's classified U.S. government contracts. If the sale has not been
completed prior to the

                                       19
<PAGE>

effective time of the merger, it will be necessary for Newbridge to transfer
ownership of the government business assets to a proxy company or make other
arrangements so that Newbridge would not be in a position to exercise FOCI
pending the sale of the government business assets to a U.S. company. Any such
arrangements will be subject to discussions with the Department of Defense and
other CFIUS representatives.

Accounting Treatment

   The merger will be accounted for by Newbridge as a purchase in accordance
with Canadian and U.S. generally accepted accounting principles.

Appraisal Rights

   Under Delaware law, you are entitled to appraisal rights in connection with
the merger. If you object to the merger, you may elect to have your shares
appraised under the procedures of the Delaware law and to be paid the fair
value of your shares. The fair value of the shares will not include any value
arising from the merger but may include a fair rate of interest. It is
possible that the fair value determined may be more or less than the merger
consideration. In order to assert these rights you must follow the procedures
set forth in Section 262 of the Delaware law. These rights are commonly
referred to as "appraisal rights" or "dissenters' rights." This proxy
statement affords stockholders of Stanford Telcom the notice required by
Section 262(d)(1) of the Delaware law. The following summary of appraisal
rights is not a complete summary of the law pertaining to appraisal rights
under the Delaware law and is qualified in its entirety by the text of Section
262 of the Delaware law, which is reproduced in Appendix E to this proxy
statement.

   This summary does not constitute a recommendation that you exercise your
appraisal rights or otherwise constitute any legal or other advice. If you
wish to exercise your appraisal rights, you are urged to contact your legal
counsel or advisors. Failure to follow strictly the procedures set forth in
Section 262 will result in a loss of your appraisal rights. If you lose your
appraisal rights, you will be entitled to receive the cash consideration
described in the merger agreement.

   Appraisal rights are available only to the record holder of shares.
References in Section 262 to "stockholders" are to record holders. References
in the summary below to "you" assume that you are a record holder. If you wish
to exercise appraisal rights but have a beneficial interest in shares which
are held of record by or in the name of another person, such as a broker or
nominee, you should act promptly to cause the record holder to follow the
procedures set forth in Section 262 to perfect your appraisal rights.

   Section 262 requires Stanford Telecom to notify you, at least 20 days prior
to the special meeting, as to the availability of appraisal rights and to
provide you with a copy of the text of Section 262.

   To claim your appraisal rights and receive fair value for your shares, you
must do each of the following:

  .  deliver to Stanford Telecom prior to the vote on the merger a written
     demand for an appraisal of your shares;

  .  continuously hold your shares from the date you make a written demand
     for an appraisal through the effective date of the merger;

  .  not vote in favor of the merger; and

  .  file within 120 days after the effective time of the merger, if Stanford
     Telecom or another stockholder does not file within that time, a
     petition in the Delaware Court of Chancery demanding a determination of
     the fair value of your shares. Stanford Telecom is under no obligation
     and has no intent to file any petition.

   If you sell or otherwise transfer or dispose of your shares before the
effective date of the merger, you will lose your appraisal rights with respect
to those shares. If neither any stockholder who has demanded appraisal rights
nor Stanford Telecom has filed a petition in the Delaware Court of Chancery
within 120 days after the effective time of the merger, then all stockholders'
appraisal rights will cease.

                                      20
<PAGE>

   Voting against the merger or otherwise failing to vote for the merger will
not by itself constitute a demand for an appraisal or sufficient notice of your
election to exercise your appraisal rights. Any demand for an appraisal must be
in writing, signed and mailed or delivered to:

                       Stanford Telecommunications, Inc.
                              1221 Crossman Avenue
                          Sunnyvale, California 94089
                              Attention: Secretary

   A written demand must reasonably inform Stanford Telecom of the identity of
the stockholder and of the stockholder's intent to demand appraisal of his, her
or its shares of Stanford Telecom common stock.

   A written demand for appraisal should be executed by or on behalf of the
stockholder of record exactly as the stockholder's name appears on the
stockholder's stock certificates. If the shares are owned of record in a
fiduciary capacity, such as by a trustee, guardian or custodian, the written
demand should be executed in that capacity, and if the shares are owned of
record by more than one person, as in a joint tenancy or tenancy in common, the
demand should be executed by or on behalf of all joint owners. An authorized
agent, including one or more joint owners, may execute a written demand for
appraisal on behalf of a stockholder of record; however, in the written demand
the agent must identify the record owner or owners and expressly disclose that
the agent is executing the demand as an agent for the record owner or owners. A
beneficial owner of shares of Stanford Telecom held in "street name" who
desires appraisal should take such actions as may be necessary to ensure that a
timely and proper demand for appraisal is made by the record holder of such
shares. Shares held through brokerage firms, banks and other financial
institutions are frequently deposited with and held of record in the name of a
nominee of a central security depository. Any beneficial holder desiring
appraisal who holds shares through a brokerage firm, bank or other financial
institute is responsible for ensuring that the demand for appraisal is made by
the record holder. The beneficial holder of such shares should instruct such
firm, bank or institution that the demand for appraisal may be made by the
record holder of the shares, which may be the nominee of a central security
depository if the shares have been so deposited. As required by Section 262, a
demand for appraisal must reasonable inform Stanford Telecom of the identify of
the holder of record and of such holder's intention to seek appraisal of such
shares. A record holder such as a broker who holds shares as nominee for
several beneficial owners may exercise appraisal rights for the shares held for
one or more beneficial owners and not exercise rights for the shares held for
other beneficial owners. In this case, the written demand should state the
number of shares for which appraisal rights are being demanded. When no number
of shares is stated, the demand will be presumed to cover all shares held of
record by the broker or nominee.

   Stanford Telecom will send notice of the effective date of the merger to
each stockholder who has properly demanded appraisal rights under Section 262
and who has not voted in favor of the merger. Stanford Telecom will send this
notice within 10 days after the effective date of the merger.

   If you have complied with the requirements for claiming your appraisal
rights under Section 262, then within the 120 days following the effective date
of the merger, you may request in writing from Stanford Telecom a statement as
to the aggregate number of shares not voted in favor of the merger and with
respect to which demands for appraisal have been received and the number of
holders of those shares. Upon Stanford Telecom's receipt of such request, which
must be made in writing, Stanford Telecom will mail a statement of that
information to you within 10 days.

   If a petition for an appraisal is filed timely and a copy is delivered to
Stanford Telecom, Stanford Telecom will then be obligated within 20 days to
provide the Register in Chancery with a duly verified list containing the names
and addresses of all stockholders of Stanford Telecom who have demanded an
appraisal of their shares and with whom agreements as to the value of their
shares have not been reached by Stanford Telecom. The Delaware Court of
Chancery will hold a hearing on the petition to determine the stockholders who
have complied with Section 262 and who have become entitled to appraisal
rights. After determining the stockholders entitled to appraisal, the Delaware
Court of Chancery shall appraise the shares, determining their fair value. The
determination of fair value will not include any element of value arising from
the accomplishment or expectation of the merger. The Court will also determine
a fair rate of interest, if any, to be

                                       21
<PAGE>

paid upon the amount determined to be the fair value of the shares. The Court
may determine that the fair value of the shares is more than, the same as or
less than the value of the cash you would have received under the merger
agreement. An investment banking opinion as to fairness from a financial point
of view is not necessarily an opinion as to fair value under Section 262. The
Delaware Supreme Court has stated that "proof of value by any techniques or
methods that are generally considered acceptable in the financial community and
otherwise admissible in court" should be considered in the appraisal
proceedings.

   The Delaware Court of Chancery may require the holders of shares who have
demanded an appraisal of their shares to submit their stock certificates to the
Register in Chancery for notation of the appraisal proceeding; and if any
stockholder fails to comply with such direction, the Delaware Court of Chancery
may dismiss the proceedings as to that stockholder.

   The costs of the appraisal proceeding may be determined by the Delaware
Court of Chancery and taxed upon the parties as the court deems equitable in
the circumstances. Upon application of a stockholder, the Court may order that
all or a portion of the expenses incurred by any stockholder in connection with
the appraisal proceeding, including, without limitation, reasonable attorneys'
fees and the fees and expenses of experts, to be charged pro rata against the
value of all of the shares entitled to appraisal.

   From and after the effective date of the merger, if you have duly demanded
an appraisal of your shares, you will not, be entitled to vote those shares for
any purpose, nor will you be entitled to the payment of dividends or other
distributions on those shares, except for dividends or other distributions
payable to stockholders of record at a date prior to the effective date of the
merger.

   You may withdraw your demand for appraisal of your shares at any time within
60 days after the effective date of the merger and accept the terms offered
pursuant to the merger. Any attempt to withdraw your appraisal demand more than
60 days after the effective date of the merger will require the written
approval of Stanford Telecom. Once a petition for appraisal is filed with the
Delaware Court of Chancery, the appraisal proceeding may not be dismissed
without court approval.

   If you properly demand appraisal of your shares, but fail to perfect your
appraisal rights, otherwise lose your appraisal rights or effectively withdraw
your demand for an appraisal, your shares will be cancelled and extinguished
and be converted into the right to receive the cash consideration described in
the merger agreement, without interest.

   Newbridge will not be obligated to close the merger if the aggregate number
of shares held by Stanford Telecom stockholders demanding appraisal rights
exceeds 10% of the number of shares of Stanford Telecom common stock issued and
outstanding immediately prior to the effective time of the merger.

                             THE MERGER AGREEMENT

   The following is a brief summary of the material provisions of the merger
agreement and the other agreements entered into in connection with the merger
agreement. This summary is qualified in its entirety by reference to the full
text of the merger agreement and the other agreements which are attached as
Appendices A through C to this document.

The Merger

   The merger will close no later than the first business day after
satisfaction or waiver of the conditions to the merger agreement, or on
another date as the parties agree. The merger will become effective upon the
filing of a certificate of merger with the Secretary of State of the State of
Delaware or at a later time as may be agreed to in writing by Newbridge and
Stanford Telecom, as specified in the certificate of merger. The closing date
is expected to be on or about December 14, 1999.

   At the effective time:

  .  Saturn Acquisition Corp. will merge with and into Stanford Telecom;

  .  the separate corporate existence of Saturn Acquisition Corp. will cease;
     and

   .  Stanford Telecom will be the surviving corporation and a wholly owned
subsidiary of Newbridge.

   Any further reference to the surviving corporation in this proxy statement
refers to Stanford Telecom following the time the merger becomes effective.

Conversion of Shares

   At the effective time, each outstanding share of Stanford Telecom common
stock (other than those cancelled by the merger agreement and any dissenting
shares), will be automatically converted into the right to receive $34.22 in
cash without interest. At or before the effective time of the merger,
Newbridge will designate a bank or trust company to act as the paying agent in
the merger. The paying agent will receive the merger consideration from
Newbridge. The paying agent will distribute the merger consideration to each
Stanford Telecom stockholder after delivery by the stockholder of their
Stanford Telecom stock certificates and a signed letter of transmittal.

   As of the effective time, each share of Saturn Acquisition Corp.
outstanding immediately prior to the effective time will be automatically
converted into one share of common stock of the surviving corporation.

Treatment of Stock Options

   At the effective time of the merger, Newbridge will, to the fullest extent
permitted by applicable law, assume all options to purchase Stanford Telecom
common stock then outstanding under Stanford Telecom's 1991 Stock Option Plan.
Each Stanford Telecom stock option, whether or not exercisable at the
effective time of the merger, to the extent permitted by applicable law, will
be assumed by Newbridge in a manner so that it will be exercisable after the
effective time of the merger upon substantially the same terms and conditions
as under the Stanford Telecom Stock Option Plan and the applicable stock
option agreement; provided that, as of the effective time of the merger,
holders of Stanford Telecom options will have the ability to "cash out" their
vested options for the difference between $34.22 and the exercise price of the
options, less applicable taxes. See the more detailed discussion under "--
Employee Benefits" below.

  .  absence of conflicts under their charters and bylaws;

                                      23

Saturn Acquisition Corp. will survive the effective time of the merger.

Conduct of Stanford Telecom's Business Prior to the Merger

   Until the earlier of the termination of the merger agreement or the
effective time of the merger, Stanford Telecom has agreed to:

No Solicitation; Board Recommendation

   Stanford Telecom has agreed that it will not take specified actions with
respect to an "acquisition proposal" or an "acquisition transaction," except
for actions that may be taken with respect to a "superior proposal."

   The term acquisition proposal means any bona fide offer or proposal made by
a third party relating to an acquisition transaction. An acquisition
transaction means any transaction or series of related transactions involving:

  .  any purchase or acquisition by any third party or any group of persons
     who have a total interest of 15% or more of the total outstanding voting
     securities of Stanford Telecom or any of its subsidiaries, or any tender
     offer or exchange offer that if completed would result in any third
     party (or its stockholders) beneficially owning 15% or more of the total
     outstanding voting securities of Stanford Telecom or any of its
     subsidiaries;

  .  any merger, consolidation, business combination or similar transaction
     involving Stanford Telecom or any of its subsidiaries;

  .  any sale, lease (other than in the ordinary course of business),
     exchange, transfer, license (other than in the ordinary course of
     business), acquisition or disposition of a material portion of the
     assets of Stanford Telecom (excluding the assets related to Stanford
     Telecom's government and contract manufacturing businesses);

  .  any liquidation or dissolution of Stanford Telecom; or


                                       26
<PAGE>

  .  the acquisition (or potential acquisition) by a third party of control
     of the Stanford Telecom board of directors or the election or
     appointment of nominees of a third party (or the ability of a third
     party to elect or appoint its nominees) to a majority of the seats on
     the Stanford Telecom board of directors.

   The term superior proposal means any bona fide acquisition proposal made in
writing and not initiated, solicited or encouraged in violation of the merger
agreement which is:

  .  on terms which the Stanford Telecom board of directors determines in
     good faith to be more favorable to Stanford Telecom and its stockholders
     or to its stockholders than the merger, after receiving written advice
     from its financial advisor that the consideration in the proposal is
     superior to the value of the merger consideration; and

  .  reasonably capable of being financed by the potential acquirer.

   Specifically, Stanford Telecom has agreed that it and its subsidiaries will
not, nor will they authorize or permit any of their officers, directors,
affiliates, agents, employees, or any investment banker, attorney or other
advisor retained by any of them to, directly or indirectly:

  .  solicit, initiate, encourage or induce the making, submission or
     announcement of any acquisition proposal;

  .  participate in any discussions or negotiations, or furnish any non-
     public information regarding an acquisition proposal, or take any other
     action to facilitate any inquiry or proposal which is or may reasonably
     be expected to lead to an acquisition proposal;

  .  engage in discussions regarding an acquisition proposal;

  .  approve, endorse or recommend any acquisition proposal; or

  .  enter into any agreement, letter of intent or similar document relating
     to any acquisition transaction.

   Stanford Telecom and the Stanford Telecom board of directors may:

  .  participate in discussions or negotiations with or furnish non-public
     information to any third party that has made an unsolicited acquisition
     proposal; and

  .  approve or accept an unsolicited acquisition proposal; but only if, in
     each case, the Stanford Telecom board of directors first:

    -- determines in good faith, after receiving written advice from its
       financial advisor, that the acquisition proposal is a superior
       proposal; and

    -- determines in good faith, after consultation with outside legal
       counsel, that the failure to participate in the discussions or
       negotiations, or to furnish the information, or approve or accept
       that acquisition proposal, would violate the Stanford Telecom board
       of directors' fiduciary duties under applicable law.

   In addition, Stanford Telecom has agreed to, within 24 hours, inform
Newbridge orally and in writing if Stanford Telecom receives an acquisition
proposal, or is asked to provide non-public information or receives an inquiry
which it reasonably believes would lead to an acquisition proposal. In each
case, Stanford Telecom has also agreed to furnish to Newbridge the identity of
the person making the proposal and/or inquiry and the material terms of the
third party's proposal, request or inquiry and to keep Newbridge informed of
the status of the proposal, request or inquiry.

   The Stanford Telecom board of directors is required to unanimously recommend
the adoption and approval of the merger agreement and approval of the merger to
the Stanford Telecom stockholders. Neither the Stanford Telecom board of
directors, nor any board committee, may withdraw, amend or modify, or

                                       27
<PAGE>

propose or resolve to withdraw, amend or modify the unanimous recommendation of
the Stanford Telecom board of directors to the Stanford Telecom stockholders in
a manner than is adverse to Newbridge unless:

  .  a superior proposal is made to Stanford Telecom and not withdrawn;

  .  Stanford Telecom gives Newbridge written notice of the superior proposal
     specifying the material terms and conditions of the proposal and
     identifying the person or entity making the proposal;

  .  Newbridge has not, within five business days of its receipt of notice of
     the superior proposal, made an offer that the Stanford Telecom board of
     directors, by a majority vote, determines in good faith, on the basis of
     the written advice of its financial advisor, to be at least as favorable
     to the Stanford Telecom stockholders as the superior proposal;

  .  the Stanford Telecom board of directors, determines in good faith, after
     consultation with outside counsel, that the recommendation to approve
     the merger would violate its fiduciary obligations to the Stanford
     Telecom stockholders under applicable law; and

  .  Stanford Telecom has not violated its non-solicitation obligations under
     the merger agreement.

   For the purposes of the merger agreement, the recommendation of the Stanford
Telecom board of directors will be modified in a manner adverse to Newbridge if
the recommendation is no longer unanimous. An action by the Stanford Telecom
board of directors or any committee is unanimous if each member of the board of
directors or committee has approved the action other than (1) any member who
has appropriately abstained from voting because of a potential conflict of
interest and (2) any member who is unable to vote in connection as a result of
death or disability.

Additional Covenants

   In connection with the merger, Stanford Telecom has agreed to:

  .  use its best efforts to sell the government and contract manufacturing
     businesses for minimum after-tax net cash proceeds of not less than $102
     million; and

  .  use all commercially reasonable efforts to amend any of its existing
     agreements that would give a third party Stanford Telecom intellectual
     property rights as a result of the merger.

   In connection with the merger, Stanford Telecom and Newbridge have agreed to
use all commercially reasonable efforts to enter into a transitional contract
manufacturing agreement with the purchaser of Stanford Telecom's contract
manufacturing facility.

   The merger agreement also contains other covenants, including obtaining
necessary consents for the merger, cooperation of the parties with respect to
any governmental filings or applications, making public announcements and
obtaining affiliates' agreements.

     complied with other than those which would not be reasonably likely to

     otherwise makes it illegal, nor will any governmental agency have
     instituted any action, suit or proceeding which remains pending and

    -- prior to the termination, a third party has publicly announced an

Employee Benefits

   Stock Options. At the effective time of the merger, to the full extent
permitted by applicable law, Newbridge will assume all of the outstanding
Stanford Telecom stock options whether or not the options are exercisable. Each
stock option assumed will continue to have and be subject to substantially the
same terms and conditions as under the Stanford Telecom stock plan under which
the stock option was granted except that:

  .  each Stanford Telecom option will be exercisable for the number of whole
     shares of Newbridge common stock, rounded down to the nearest whole
     share, equal to the product obtained from multiplying the number of
     shares of Stanford Telecom common stock covered by the option
     immediately prior to the effective time by the option exchange ratio,
     which is equal to $34.22 divided by the average of the daily average of
     the high and low prices of the Newbridge common stock on the New York
     Stock Exchange for the five trading days ending the second trading day
     before the special meeting; and

  .  the option price per share of Newbridge common stock will be equal to
     the quotient obtained from dividing the option price per share of
     Stanford Telecom common stock subject to the option in effect
     immediately prior to the effective time by the option exchange ratio,
     rounded up to the nearest whole cent.

   In addition, persons holding Stanford Telecom options which are vested or
will be vested at the effective time of the merger will be able to exercise
those options on a "cash-out" basis as of the effective time of the merger.
Option holders who exercise their options in this manner will receive, after
the effective time of the merger, a cash payment for each share exercised equal
to $34.22 less the exercise price of the shares and any applicable withholding
or employment taxes.

   Newbridge will file a registration statement on Form S-8 or other
appropriate form under the Securities Act covering the shares of Newbridge
common stock issuable upon exercise of the options assumed in the merger not
later than ten business days after the effective time of the merger.

   Employee Stock Purchase Plan. Pursuant to the merger agreement, Stanford
Telecom's 1992 Employee Stock Purchase Plan was terminated following the
purchase of shares on September 30, 1999. All funds contributed to the 1992
Stock Purchase Plan that were not used to purchase shares of Stanford Telecom
common stock were returned to the Stanford Telecom employees in accordance with
the 1992 Stock Purchase Plan.

   Other Benefit Plans. Contributions under Stanford Telecom's 401(k) plan will
continue in accordance with past practice up to and including the closing date
of the merger. Payments to employees under Stanford Telecoms profit sharing
program and Stanford Telecom's management incentive plan will continue up to
and including the closing date of the merger in accordance with practice.

request or are terminated on or within 90 days of the effective time of the
merger will be paid severance equal to one year's base salary. Other Stanford
Telecom employees who are terminated on or within 90 days of the effective time
of the merger will be paid severance equal to the greater of one month's salary

Technology License Option Agreement

   Stanford Telecom has granted Newbridge an option to acquire a license to its
intellectual property to make and distribute wireless broadband products upon
the terms and subject to the conditions set forth in the Technology License
Option Agreement. The following is a brief summary of the material terms of the
Technology License Option Agreement, which is attached as Appendix B to this
proxy statement and incorporated herein by this reference. This summary is
qualified in its entirety by reference to the Technology License Option
Agreement.

   The option is exercisable by Newbridge at an exercise price of $69 million
at any time after a change in control of Stanford Telecom. A change in control
means the occurrence of an acquisition transaction, except that a spin-off of
Stanford Telecoms wireless broadband products business through a distribution
to Stanford Telecom stockholders will not constitute an acquisition
transaction, unless subsequent to the spin-off and during the period the option
is still exercisable, an acquisition transaction occurs involving the new
company conducting the wireless broadband products business.

   The option will continue to be exercisable until the earliest of:

  .  May 24, 2001;

  .  nine months after the termination of the merger agreement by Newbridge
     if the agreement has been terminated because Stanford Telecom has
     breached any of its representations or warranties;

Stock Option Agreement

   In connection with the merger, Stanford Telecom has granted to Newbridge an
irrevocable option to acquire a number of shares of Stanford Telecom common
stock equal to 19.9% of the issued and outstanding Stanford Telecom shares as
of the first date the option becomes exercisable. The following is a brief
summary of the material terms of the stock option agreement, which is attached
as Appendix C to this proxy statement and incorporated herein by this
reference. This summary is qualified in its entirety by reference to the stock
option agreement.

   Newbridge may exercise the option at any time after the occurrence of one of
the following exercise events:

  .  triggering event; or

  .  the public announcement of an acquisition proposal.

   The option is exercisable at a purchase price of $35 per share and will
expire upon the earliest of:

  .  the effective time of the merger;

  .  the termination of the merger agreement if no exercise event has
     occurred and the merger agreement is terminated:

    -- by the mutual consent of Newbridge, Saturn Acquisition Corp. and
       Stanford Telecom;

    -- as a result of a governmental order or decree;

    -- due to the breach of representations or warranties by either party;
       or

  .  18 months following termination of the merger agreement for any other
     reason.

   If Newbridge acquires the option shares and the proceeds from any sale of,
or dividend on, the option shares, plus any termination fee received by
Newbridge under the merger agreement exceeds the sum of (1) $25 million plus
(2) the exercise price of the option shares purchased by Newbridge, then all
proceeds in excess of that aggregate amount will be repaid by Newbridge to
Stanford Telecom.

   Upon notice (the "Put Notice") by Newbridge during the period in which the
option is exercisable, if Stanford Telecom consummates an acquisition
transaction or enters into an agreement providing for an acquisition
transaction, Stanford Telecom, or any successor entity, will purchase:

  .  the options not exercised by Newbridge at a per share price equal to the
     difference between the Market/Tender Offer Price (as defined in the
     stock option agreement) and $35 as of the date of the Put Notice; and

  .  any option shares acquired by Newbridge at a per share price equal to
     (1) the exercise price paid by Newbridge for the option shares plus (2)
     the difference between the Market/Tender Offer Price and $35.

   If Newbridge acquires option shares and neither (1) an acquisition
transaction has been completed within 18 months after the termination of the
merger agreement nor (2) has Stanford Telecom entered into an agreement which
remains in effect at the end of the 18-month period, then Stanford Telecom may
repurchase any option shares held by Newbridge at $35 per share.

   Following the termination of the merger agreement, Newbridge may require
Stanford Telecom to register under the Securities Act all or any part of the
option shares acquired by Newbridge under the stock option agreement.

             PROPOSAL NO. 2--SALE OF THE GOVERNMENT BUSINESS ASSETS

   You are being asked to approve the sale of Stanford Telecom's government
business assets to a third party. The government business accounted for 71.3%
of Stanford Telecom's revenues in fiscal 1998 and 74.6% in fiscal 1999.

   Stanford Telecom has entered into an agreement with ITT Industries, Inc. to
sell to ITT Industries the government business assets for $191 million, subject
to adjustment based on the net worth of the government business on the closing
date of the sale. This agreement is subject to a number of conditions. As a
result, we cannot assure you that the sale to ITT Industries will be completed
or that it will be completed at this price. If we do not sell the government
business assets to ITT Industries, we will seek to sell the government business
assets to another party. Approval of the proposal for the sale of the
government business assets to a third party will also constitute approval of
the sale to ITT Industries.

   If the Stanford Telecom stockholders do not approve the sale of the
government business assets or if the sale of the government business assets has
not been completed prior to the merger, the merger will be completed and
Newbridge will effect the sale of the government business assets after the
merger. Stanford Telecom does not intend to sell the government business assets
if the merger with Newbridge is not approved by its stockholders and completed
under the terms of the merger agreement.

Background of the Sale of the Government Business Assets

   In May 1999, CIBC World Markets Corp., on behalf of Newbridge, began working
with Stanford Telecom to provide assistance in identifying purchasers and
facilitating the sales of Stanford Telecom's government and contract
manufacturing businesses. A confidential offering memorandum describing the
government business was prepared for distribution to potential purchasers.

   In May 1999, more than 40 potential purchasers were contacted in connection
with the sale of the government business assets. Thirty-six of those contacted
signed confidentiality agreements with Stanford Telecom and were provided with
copies of the offering memorandum.

   Potential purchasers were asked to submit non-binding indications of
interest. Stanford Telecom received indications of interest from 11 potential
purchasers for the government business assets by July 12, 1999. Of the
interested parties, a limited number of parties were invited to continue in the
sale process and begin due diligence review of the government business assets.

   On July 23, 1999, Stanford Telecom provided each potential purchaser of the
government business assets with a draft agreement and bidding procedures for
the transaction.

   Stanford Telecom received three final bids from potential purchasers on
August 6, 1999. From August 9 to August 18, 1999, CIBC World Markets Corp.
discussed with each of the bidders the terms and conditions of their respective
bids.

   On August 20, 1999, representatives of CIBC World Markets Corp. called
representatives of ITT Industries to inform the representatives of ITT
Industries that Stanford Telecom desired to continue discussions relating to
the negotiation of a definitive agreement for the sale of the government
business assets.

   On August 25, 1999, Mr. Gary S. Wolf, Executive Vice President of Stanford
Telecom, Mr. Ralph Meoni, Vice President and Director of Corporate Development
and Operations Support of ITT Defense (a division of ITT Industries), Mr.
Lawrence Swire, Vice President and Associate General Counsel of ITT Industries,
Mr. Peter Nadeau, Vice President and General Counsel of Newbridge and
representatives of Simpson Thacher & Bartlett, counsel to ITT Industries,
Thelen Reid & Priest LLP, counsel to Stanford Telecom, Heller Ehrman White &
McAuliffe, counsel to Newbridge, and CIBC World Markets Corp., financial
advisor to Newbridge, met in San Jose, California to negotiate the terms of the
transaction.

                                       36
<PAGE>

   On August 31, 1999, Dr. Val Peline, President and Chief Executive Officer of
Stanford Telecom, Mr. Martin Kamber, Executive Vice President of ITT
Industries, Messrs. Wolf, Meoni, Swire and Nadeau and representatives of
Simpson Thacher & Bartlett, Thelen Reid & Priest LLP, Heller Ehrman White &
McAuliffe and CIBC World Markets Corp. held a teleconference call to negotiate
further the terms of a definitive agreement relating to the sale of the
government business assets.

   From August 31, 1999 to September 2, 1999, representatives of Stanford
Telecom, ITT Industries and Newbridge met to review and discuss matters related
to the separation of Stanford Telecom's government business assets and
transition matters related to the transfer of the government business assets
from Stanford Telecom to ITT Industries.

   On September 2, 1999, Dr. Peline, Mr. Robert Seitter, Assistant General
Counsel and General Patent Counsel of ITT Industries, Messrs. Wolf, Kamber,
Meoni and Swire, and representatives of Simpson Thacher & Bartlett, Thelen Reid
& Priest LLP, Heller Ehrman White & McAuliffe and CIBC World Markets Corp. held
a teleconference to discuss the separation of Stanford Telecom's government
business assets.

   From September 2, 1999 through September 22, 1999, management of Stanford
Telecom, ITT Industries and Newbridge and their legal and financial advisors
continued to negotiate the terms of a definitive agreement.

   At a meeting held on September 16, 1999, the Stanford Telecom board of
directors reviewed and discussed the terms of the proposed transaction. The
Stanford Telecom board of directors unanimously approved the sale of the
government business assets to ITT Industries and authorized the officers of
Stanford Telecom to finalize and execute the asset purchase agreement.

   The definitive asset purchase agreement was signed on behalf of ITT
Industries and Stanford Telecom on September 22, 1999.

Reasons for the Sale of the Government Business Assets

   The merger agreement with Newbridge contemplates the sales of Stanford
Telecom's government and contract manufacturing businesses. As a Canadian
corporation, Newbridge would be prohibited from performing Stanford Telecom's
classified contracts with the U.S. government unless steps were taken to
mitigate foreign ownership, control and influence by means such as
establishment of a proxy company or voting trust to manage the operation of the
government business.

   Stanford Telecom currently anticipates that the sale price of the government
business assets will be approximately $191 million, based on the results of the
auction process by CIBC World Markets Corp. and the agreement with ITT
Industries. In determining the adequacy of the anticipated sale price, the
Stanford Telecom board of directors consulted with Stanford Telecom management
and reviewed and analyzed the historical financial results and future prospects
of the government business, comparable valuations of businesses similar to
those of the government business to the extent that comparable information was
available from public and private transactions and other relevant information.

   The Stanford Telecom board of directors determined that selling the
government business assets in connection with the merger with Newbridge is in
the interests of the Stanford Telecom stockholders because it enables the
stockholders to share in the proceeds from the sale. See "The Merger
Agreement--Conversion of Shares" for information as to how the Stanford Telecom
stockholders will share in the proceeds. See "The Merger--Stanford Telecom's
Reasons for the Merger" for information as to why the Stanford Telecom board of
directors determined that the terms of the merger with Newbridge, which
includes the sale of the government business assets, are in the best interests
of the Stanford Telecom stockholders.

Recommendation of the Stanford Telecom Board

   After careful consideration, the Stanford Telecom board has approved the
sale of the government business assets, and has specifically approved the sale
of the government business assets to ITT Industries.

                                       37
<PAGE>

   The Stanford Telecom board unanimously recommends that the Stanford Telecom
stockholders vote "for" approval of the sale of the government business assets.

Interests of Executive Officers of Stanford Telecom in the Sale of the
Government Business Assets

   In considering the recommendation of the Stanford Telecom board of directors
with respect to the sale of the government business assets, you should be aware
that some of the Stanford Telecom executive officers have interests in the sale
that are different from, or are in addition to, yours. These interests may
include severance payments and accelerated vesting of stock options. In
addition, some of the executive officers may enter into employment agreements
with the purchaser of the government business assets.

   If the government business assets are sold to ITT Industries, two of
Stanford Telecom's executive officers are expected to be employed by ITT
Industries. ITT Industries will not assume any of the Stanford Telecom stock
options. As a result, Stanford Telecom intends to accelerate the vesting of the
options as of the effective date of the merger with Newbridge. See "The
Merger--Interests of Executive Officers and Directors of Stanford Telecom in
the Merger--Accelerated Vesting of Stock Options" on page 17.

Regulatory Approvals

   Hart-Scott-Rodino. In connection with the sale of the government business
assets, Stanford Telecom and the purchaser of the government business assets
need to file notification and report forms with the FTC and the Antitrust
Division of the United States Department of Justice and satisfy the specified
waiting period requirements under the Hart-Scott-Rodino Antitrust Improvements
Act of 1976 and the rules thereunder. Stanford Telecom and ITT Industries each
filed notification and report forms relating to the sale of the government
business assets under the Hart-Scott-Rodino Act with the FTC and the Antitrust
Division on October 1, 1999, and the waiting period terminated on October 14,
1999.

   Federal Acquisition Regulation. Federal law prohibits the transfer of U.S.
government contracts from a contractor to a third party unless the government
recognizes that third party as the successor in interest to the contract or
contracts and enters into a novation agreement. In connection with the sale of
Stanford Telecom's government business assets, it will be necessary to obtain
that recognition and to enter into a novation agreement or agreements with the
government in accordance with the provisions of the Federal Acquisition
Regulation. In determining whether such recognition is in the interest of the
government, the government considers a number of factors concerning the
prospective transferee's capability to perform the contracts and responsibility
as a prospective contractor and evidence that any security clearance
requirements have been met.

Accounting Treatment

   The sale of the government business assets will be accounted for by Stanford
Telecom as a sale of assets in accordance with U.S. generally accepted
accounting principles. Stanford Telecom expects to record a gain on its
financial statements for the difference between the total proceeds from the
sale of the government business assets and the net book value of those assets.

Appraisal Rights

   Under Delaware law, you will not have "appraisal rights" or "dissenters'
rights" in connection with the sale of the government business assets.

Federal Income Tax Consequences

   The following is a general summary of the principal federal income tax
consequences to Stanford Telecom of the sale of the government business assets.
It does not address any state or local tax consequences. Stanford

                                       38
<PAGE>

Telecom stockholders are advised to consult with their tax advisors for a more
detailed analysis of any federal, state or local tax consequences.

   The sale of the government business assets will be a taxable transaction to
Stanford Telecom. Stanford Telecom expects that the net proceeds of the sale
will exceed the adjusted tax bases of the assets and that, accordingly,
Stanford Telecom will realize a taxable gain. For more information regarding
the federal income tax consequences to Stanford Telecom stockholders in
connection with the merger, see "The Merger--Material United States Federal
Income Tax Consequences."

The Government Business Asset Purchase Agreement

purchase agreement with ITT Industries. Pursuant to the asset purchase
agreement, ITT Industries has agreed to purchase the assets of Stanford
Telecom's government business. The closing of the sale of the government
business asset sale is expected to take place on or about December 14, 1999.

   The following is a brief summary of the material provisions of the asset
purchase agreement between ITT Industries and Stanford Telecom. This summary is
qualified in its entirety by reference to the asset purchase agreement filed by
Stanford Telecom as an exhibit to its Current Report on Form 8-K filed with the

 Purchase Price

   ITT Industries will purchase the government business assets for $191 million
in cash, subject to adjustment if the net book value of the assets and
liabilities of the government business as of the closing date is greater or
less than $40.2 million. The amount to be paid by ITT Industries at the closing
will be based on the parties' estimate of the net worth of the government
business assets as of the closing date. ITT Industries will have the
opportunity to audit the estimated net worth after the closing. The purchase
price will be adjusted up or down following the audit, if the audited net worth
differs from the estimated net worth by more than $1 million.

   Any sales, purchase or use tax which may be payable as a result of the asset
purchase agreement or the transactions contemplated by the agreement will be
paid by ITT Industries.

 Termination of the Asset Purchase Agreement

   The asset purchase agreement may be terminated at any time prior to the

  .  by either ITT Industries or Stanford Telecom if the asset sale has not
     closed by March 31, 2000 (provided that the right to terminate the asset
     purchase agreement will not be available to any party whose action or
     failure to act has proximately contributed to the failure to close the
     asset sale by March 31, 2000 and the action or failure to act
     constitutes a breach of the asset purchase agreement);

  .  by either ITT Industries or Stanford Telecom if:

    -- a statute, rule, regulation or executive order has been enacted,
       entered or promulgated prohibiting consummation of the asset sale
       substantially on the terms contemplated by the asset purchase
       agreement;

    -- the U.S. government advises that it will not enter into a novation
       agreement with respect to any of the government contracts identified
       in the asset purchase agreement; or

    -- a court of competent jurisdiction or other government body has
       issued a final and non-appealable order, decree, ruling or
       injunction, or taken any other action, having the effect of
       permanently restraining, enjoining or otherwise prohibiting the
       asset sale substantially on the terms contemplated in the asset
       purchase agreement (provided that a party exercising the right to
       terminate has used its reasonable efforts to remove that order,
       decree, ruling or injunction);

  .  by Stanford Telecom or ITT Industries upon breach by the other party of
     its representations and warranties in a manner that the closing
     conditions have not been met, if that breach has not been cured within
     30 days after notice of the breach has been received by the party
     allegedly in breach; provided that neither party may terminate the
     agreement if it has breached in any material respect its obligations
     under the asset purchase agreement in any manner that proximately caused
     the breach by the other party; or

  .  by ITT Industries or Stanford Telecom, if after the date of the asset
     purchase agreement, events occur or circumstances exist that will
     prevent satisfaction before March 31, 2000 of the conditions to the
     terminating party's obligations.

 Post-Termination Options To Purchase

   If the merger of Stanford Telecom with Newbridge is not completed and, as a
result, the sale of the government business assets is not completed, and if
prior to June 30, 2000 Stanford Telecom decides to sell the government business
assets, in whole or in part, then before the assets may be sold to a third
party ITT Industries would have the right to purchase the government business
assets that Stanford Telecom decides to sell. If Stanford Telecom decides to
sell all of the government business assets, then the terms of the sale,
including the purchase price, would be substantially the same as in the current
asset purchase agreement, provided that if Stanford Telecom receives a superior
offer for the government business assets from a third party, then ITT
Industries would have the right to purchase the government business assets on
the terms of the superior offer.

   Stanford Telecom has agreed that, in the event the merger and the sale of
the government business assets are not completed, neither it nor any of its
employees, affiliates or other representatives will take specified actions
prior to June 30, 1999 to encourage or induce a third party to offer to
purchase any of the government business assets, unless the action is necessary
in order for the Stanford Telecom board of directors to fulfill its fiduciary
duties to the Stanford Telecom stockholders.

                          BUSINESS OF STANFORD TELECOM

   Stanford Telecom designs, manufactures, and markets advanced digital
communications products and systems to establish or enhance communications via
satellites, terrestrial wireless and cable. Our technical strengths include:
system design, communication waveforms, modulation and demodulation techniques,
ASIC design, Radio Frequency (RF) antennas and downconverters, software and
firmware, Asynchronous Transfer Mode (ATM) design and advanced manufacturing
techniques and processes.

   Stanford Telecom was incorporated in California in 1973 and reincorporated
in Delaware in 1988.

Government Business

   Our government business is conducted through four divisions: Satcom Ground
Systems, Communications Systems Integration, Applied Technology Operation and
Advanced Communications Systems. Our ground equipment supports many of the
Department of Defense high priority satellites including military
communications satellites such as Defense Satellite Communications System (DSCS
III) and MILSTAR, as well as Global Positioning Systems (GPS), the
military/civil navigation satellite system.

 DSCS Operational Control System

   We provide critical on-site operations and maintenance support, software
support, integrated logistic support, training and depot support services for
the U.S. Army's DSCS program under a five-year contract called DSCS Operations
Control System Support Services (DOCS3). We have been performing critical
services in support of DSCS for the U.S. government since 1981.

   The DOCS is a complex collection of network management and control
subsystems that are used as tools for managing DSCS ground station and space
communication payload assets. The DSCS must be operated and maintained at peak
efficiency and maximum availability as it is often the only means of
communication with deployed forces.

   Over the past two years, the U.S. government has issued individual task
orders for system adaptation tasks. These tasks often require hardware and/or
software enhancements and modifications to extend the life expectancy of the
system. The addition of these tasks to the base contract makes DOCS3 our
largest single contract.

 Global Broadcast Services

   The U.S. government counterpart to Direct Broadcast Satellite (DBS)
television is the Global Broadcast Service. This military satellite system
operates in the Ka- and Ku-bands using special payloads on UFO Follow-on
Satellites. We provide the uplink terminals termed the Primary Injection Point
(PIP) and Tactical Injection Point (TIP) terminals.

   During the past year, we integrated and delivered two Global Broadcast
Service (GBS) Primary Injection Points terminals, under subcontract to Raytheon
Information Systems Company. We were awarded options to design, manufacture,
and deliver the initial Transportable Injection Point for the GBS program. The
TIP, comprised of a Transportable Satellite Broadcast Manager and a
Transportable Theater Injection terminal, will be installed on High Mobility
MultiWheeled Vehicles (HMMWV) and provide GBS uplink capability from deployed
locations worldwide. Stanford Telecom anticipates additional TIP orders during
fiscal 2000.

 Digital Satellites Terminals

   The DST satellite communications terminals differ from many other satellite
terminals in that they operate with both military X-band satellites and
commercial C- and Ku-band communications satellites. We design, manufacture and
deliver commercial earth stations that offer highly reliable communications
over military and commercial satellite systems operating in C-, X-, and Ku-
bands.

                                       45

 Replacement Satellite Configuration Control Element

   We have a production contract for the manufacture, test and installation of
the Replacement Satellite Configuration Control Element (RSCCE), a critical
component of the U.S. Army's Defense Satellite Communications System (DSCS).
The RSCCE system we developed completed formal acceptance and operational
testing in December 1998. Our RSCCE provides satellite commanding and telemetry
monitoring and processing capabilities to the U.S. Army at the DSCS Operations
Centers located worldwide. The production contract also includes an additional
development phase during which the system will be enhanced to provide
operational capabilities requested by the customer. This program is scheduled
to last about four years and will culminate with the installation of 18 RSCCE
systems in late 2002 and 2003.

 RBATSON Satellite Command Systems

   The U.S. Army Communications Electronics Command (CECOM) exercised a major
production option on the Replacement BATSON (RBATSON) program during fiscal
1999. The RBATSON program, originally awarded to Stanford Telecom in December
1996, is a technology insertion effort, which replaces 1970's era BATSON
cryptographic security equipment for DSCS ground control stations with new
form, fit, and function replacement units. The RBATSON system (KI-34) consists
of two components, the KIG-34 and the KIT-34, and new Maintenance Test
Equipment (MTE), also known as the KT-43A.

   We are now under contract to produce and deliver 17 additional RBATSON units
(KIG-34s and KIT-34s) and 2 KT-43, and their associated spares. CECOM also
approved two engineering change proposals, which increase the capabilities of
the MTE.

 GPS Block IIF Satellite Test System

   We are under contract to deliver a state-of-the-art factory test system to
Boeing North American for use in factory testing of the next generation Global
Positioning System (GPS) Block IIF satellites. The system consists of a
combination of modern Commercial-Off-The-Shelf test equipment and Stanford
Telecom designed GPS equipment. Specially developed Stanford Telecom software
controls the equipment and digitally processes measurement data to provide
extremely accurate determination of critical satellite parameters. The test set
is fully automated to significantly reduce satellite test time and to reduce
the effect of "human error" in the measurement process.

 Atmospheric Sensing Systems

   We have developed a new type of atmospheric turbulence monitoring instrument
that measures the strength and rate of change of atmospheric turbulence. The
measurements are essential for the design of systems with applications that
depend on the ability to bring light to a sharp focus. In particular, the
measurements are essential to those that use the technique known as adaptive
optics to partially cancel the distorting effects of the atmosphere.

   We have a dedicated facility on the grounds of the George Washington
University Northern Virginia Campus for the development and test of new optical
and RF atmospheric sensing systems. This facility includes an astronomical
observation center including a weather station and a local operations center
for collection and processing of atmospheric data.

 Milstar Instrumented Calibration Terminal

   We recently delivered three transportable MILSTAR Instrumented Calibration
Terminals to Lockheed Martin to conduct on-orbit tests of the MILSTAR
satellites at various locations throughout the world. This terminal is based on
our proprietary MILSTAR Transportable Terminal System. The terminal will be
able to test both the current MILSTAR I and the soon to be launched next
generation MILSTAR II satellites.

                                       46
<PAGE>

 Microwave Signal Products

   We are developing wide bandwidth, GHz-rate microwave products for high-data
rate communications and high-resolution radars.

   We completed the first two production phases of the synthesizer for the
Army's SCAMP Portable MILSTAR Satellite Terminal. The synthesizer is a key
component of this satellite terminal. Since it will be used by soldiers in the
field, the terminal must be lightweight and run on battery power for extended
periods. Using cost effective commercial manufacturing practices, we were
recently authorized to proceed with the third phase of the contract along with
options, extending this contract though fiscal 2001.

 Direct Digital Chirp Synthesizer

   The STEL-2375 is being used to support customer requirements in diverse
applications such as commercial automotive test equipment and state-of-the-art
radars for missiles and aircraft. The chip is implemented in high-speed GaAs
technology to run at a leading edge rate of 1 GHz clock rate.

 Direct Digital Synthesizer

   The STEL-9944 builds on our earlier success with our STEL-2373 DDS
Synthesizer that has been designed into aircraft radars such as the F-18 and
the newer F-22. The STEL-9944 developed for the SM-II Missile program is now in
full production having successfully passed our engineering pre-production
phase.

 NASA Tracking and Data Relay Satellites

   We support NASA in its major communications satellite program, the Tracking
and Data Relay Satellite that provides communication to the Space Shuttle. We
continue our 22 years of support to NASA's Tracking and Data Relay Satellite
System including both systems engineering services and hardware and software
development, which includes:

  .  Low Power Programmable Transceiver (LPT), which utilizes innovative
     state-of-the-art technology to develop a multifunctional low power space
     based transceiver. One version of the LPT integrates GPS with the
     transceiver.

  .  Software Programmable Advanced Receiver (SPAR), which applies advanced
     signal processing into a software-programmable radio that provides
     highly flexible communication support across a broad range of signaling
     formats, spread-spectrum operations, and integrated tone ranging. The
     SPAR has successfully supported two Titan IV-B launches where it is used
     to receive signals from the Inertial Upper Stage (IUS). On its last
     mission it stayed in lock and tracked telemetry though the thermal roll
     maneuvering of the rocket, a period when dropout of the signal due to
     antenna misalignment was expected to cause the SPAR to lose signal lock.
     The SPAR's performance has been highly praised by NASA.

  .  Third Generation Beamforming System (TGBFS), which will provide low-
     cost, ground-based beamforming of TDRSS-phased array signals for
     emerging users of NASA's Demand Access System. The TGBFS applies state-
     of-the-art optical and digital processing with applicability to smart,
     adaptive antennas.

  .  Space Station Early Communication System (ECOMM), which is an S-band
     receiver that provides a spread-spectrum, command and telemetry data
     link, and a high-rate video conferencing link for International Space
     Station astronauts. Two ECOMM terminals are currently deployed on the
     Space Station.

 Next Generation GPS Signal Design

   We also support the U.S. government in the Global Positioning System (GPS),
the U.S. satellite navigation system. We are working with the Air Force through
Boeing Corporation to investigate candidate

                                       47
<PAGE>

signals for the next generation GPS signal structure. The U.S. Administration
recently announced that the next generation GPS signal would include both new
civil and military signals. Stanford Telecom is helping to design these
signals.

 Federal Aviation Administration

   We have been supporting the FAA for the past 20 years. This past year we
have provided support in the following areas:

  .  Communication: Supported the development of requirements for the
     modernization of the FAA's Operation Network.

  .  Automation: Supported planning and engineering for the upgrading of the
     Enroute Automation System.

  .  Surveillance: Supported planning and engineering for the upgrading of
     the surveillance automation processing subsystem.

  .  Security: Supported planning and engineering for the security of the NAS
     Automated System.

  .  Navigation: Supported the Satellite National Testbed.

   We also provide engineering support to the FAA's Telecommunications
Integrated Product Team (TIPT). These engineering efforts will be focused on
support to the continued effective operation of the existing networks as well
as planning and supporting the implementation of network modernization to allow
the FAA to meet the challenges of the 21st century. The FAA's TIPT is
responsible for providing the communications infrastructure essential to the
accomplishment of the FAA's mission.

Wireless Broadband Business

   There are two separate but closely related wireless broadband communications
systems: Multichannel Multipoint Distribution System (MMDS), sometimes called
wireless cable operating in the 2.5 GHz frequency band, and the wider bandwidth
Local Multipoint Distribution System (LMDS) that operates in the 28-31 GHz
frequency region. The FCC completed the auction of the LMDS frequencies in
March 1998.

   We have increased our investment in the development of a product line of
modems and service interface cards that will enable wireless delivery of high-
speed data and telephony services to commercial and residential customers. Our
product line supports a true point-to-multipoint architecture which uses large
TDM downstream channels and smaller bandwidth-on-demand upstream channels to
provide ATM transport of multimedia services to small-to-medium sized
businesses and home offices. A complete product line has been developed which
offers both data and a variety of telephony services. The simplest customer
premise product suitable for the small office provides a single 10Mbps data
line and two analog telephone connections. More sophisticated users can be
provided with additional capability of up to two data lines and eight T1 (or
E1) connections for a single user. Our family of wireless broadband products
are capable of operating over a wide range of frequencies with programmable
data rates.

   Technology demonstrations and field trials using prototype hardware and
software were successfully completed during fiscal 1999. At year-end, hardware
development was essentially complete, with low volume production deliveries
under way for initial deployments in Canada, Europe, and the United States. Our
customers forecast a rapid acceleration of production orders in fiscal 2000.
Software development is essentially complete, with a period of final testing
and evaluation planned for the first quarter of fiscal 2000.

   Strong market interest continues in both the United States and offshore. We
have responded to several opportunities with our partners and expect that we
will see strong market expansion in Europe, Latin and South America, and Asia.
In the U.S., a significant consolidation of spectrum holders took place after
the completion

                                       48
<PAGE>

of the auction process, and it now appears that the major LMDS spectrum holders
are dedicated to begin nationwide deployment. On the MMDS front, two national
interexchange carriers have acquired spectrum that will allow them to deploy
wireless data and telephony networks in many regions throughout the U.S. This
acquisition is seen as a very positive development for the MMDS industry and
will likely result in deployment decisions later this year.

   We have developed an extensive and very flexible product line for LMDS and
MMDS equipment to support both telephony and high-speed Internet access. These
products include headend and subscriber equipment and network management
systems.

General

 Manufacturing

   Our products are generally manufactured from standard components, our
proprietary ASICs and other components or subsystems produced to our
specifications. Most of our current products contain microprocessors for which
proprietary software is designed and tested by our engineers. We do not have a
semiconductor foundry or fabrication facility. For the production of ASICs, we
contract with companies that have foundry capability.

   In many cases only a single source is available for specific components, and
thus there is a risk of delay in delivering finished systems within contractual
schedules. We attempt to minimize this risk by securing second sources, finding
alternate technologies to perform the same function and maintaining adequate
inventories of single source components. Many of our products are covered by a
90-day to one-year warranty under which we will repair or replace defective
parts. To date, warranty expense has not been significant.

 Marketing and Customers

   We market our products and services to agencies of the U.S. government,
prime contractors to these agencies and an increasing number of commercial
customers. Our marketing is conducted by our management and technical staff,
and in the case of our commercial business, domestic and international sales
representatives are also utilized. Our marketing efforts for our government
business consist of responding to requests for proposals and solicitations for
bids from U.S. government agencies or prime contractors to these agencies and
direct marketing of our off-the-shelf, standardized products. We also place
advertisements for commercial products, particularly our Wireless Broadband
(LMDS/MMDS) products, in a number of trade magazines and participate in trade
shows and industry symposiums. In some cases, the major communication system
integrators who are pursuing wireless broadband opportunities market our
products directly to the service providers. We are requested to support these
marketing activities from time to time.

 Competition

   Competition is intense among providers of digital telecommunications
equipment, products and services. In the government base business, competitors
include major defense contractors, telecommunications equipment and electronics
firms, and systems integrators, most of which have significantly greater
financial, marketing and operating resources than we do, as well as broader
product lines and technological capabilities. As a result of reduced defense
spending by the U.S. and other governments, competition has become more intense
in the government base business. Although no single competitor competes with us
in all of our product lines, a number of competitors such as Harris
Corporation, Loral-Space, Lockheed-Martin, TRW, BDM, Hughes, and CSC compete
with us in various market segments. Certain of our customers have technological
capabilities in our product areas and could choose to develop and manufacture
certain products themselves rather than purchase from us.

                                       49
<PAGE>

 Backlog and Bookings

   Funded backlog includes: (i) projects and orders covered by signed contracts
for which the government has specifically allocated funding; and (ii) purchase
orders from commercial customers. Our backlog is largely attributable to
agencies of the U.S. government. In the case of certain long-term contract
awards, the U.S. government typically makes the funds available over the life
of the contract as opposed to the time of the contract award. In such cases we
report as funded bookings only the amount of the funds specifically allocated
and the resultant backlog as funded backlog. We do not include unexercised
options in backlog. Our contracts typically contain contingency provisions
permitting termination by the customer at any time. Cancellation of pending
contracts or termination or reductions of contracts in progress may have a
material adverse effect on our results of operations.

 Research and Development

   The telecommunications industry is characterized by rapid technological
change, requiring a continuous effort to enhance existing products and develop
new products. We conduct extensive research, development and engineering
activities with the objective of developing products and systems that provide
for cost-effective, digital wireless telecommunications and high-quality
satellite communications. We have developed a number of innovative and
proprietary digital telecommunications technologies through a combination of
customer and internally funded research and development.

   Our revenues have historically been derived primarily from performing
contract research and development and engaging in limited production contracts
with agencies of the U.S. government and their prime contractors. As a result,
a substantial portion of the digital telecommunications research and
development we have performed has been funded by our customers.

 Employees

   As of September 30, 1999, we employed 1,019 full-time and 23 part-time
employees and 19 professional consultants. Of the full-time employees, 603 are
in technical operations, 113 in manufacturing operations, 130 in management,
105 professional non-technical, and 68 in support positions. The majority of
our employees are highly skilled technical personnel. Several are nationally
known leaders in the field of digital telecommunications. None of the employees
are represented by a labor union and we have never had a work stoppage. We
believe our employee relations to be good. Due to the nature of our business, a
large number of our technical employees must obtain security clearances from
the U.S. government, which limits the available pool of eligible candidates for
such positions to those who can satisfy prerequisites for such clearances.

 Government Regulation

   Our operations are subject to compliance with regulatory requirements of
federal, state and local authorities, including regulations concerning
employment obligations and affirmative action, workplace safety and protection
of the environment. In addition, many of our products and proposed products are
or will be subject to various regulations including regulations promulgated by
the FCC, the FAA and the Department of Defense.

   We must comply with detailed government procurement and contracting
regulations and with U.S. government security regulations, including those
necessary to maintain required facility clearances. Certain of these
regulations carry substantial penalty provisions for nonperformance or
misrepresentation in the course of negotiations. Failure to comply with our
government procurement, contracting or security obligations could result in
penalties or our suspension from government contracting, which would have a
material adverse effect on our results of operations.

   We are required to maintain a U.S. government facility clearance at most of
our locations. This clearance could be suspended or revoked if we are found not
to be in compliance with applicable security regulations. Any such revocation
or suspension would delay our delivery of our products to customers.

 Properties

   Our headquarters and principal engineering and manufacturing facilities are
currently located in four adjacent buildings in Sunnyvale, California where we
lease approximately 172,000 square feet. Our Sunnyvale facility leases will
expire in December 2000. We also lease the following premises, primarily for
the performance of study, system engineering and hardware contracts:

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATION

Company Overview

   Since our inception in 1973, revenues have been generated primarily from
sales to agencies of the U.S. government, including the Department of Defense,
the U.S. Air Force, Army and Navy, NASA and the FAA, or their prime
contractors. Such revenues are generated from many contracts including programs
requiring multi-year hardware and software development and limited production
of products and systems. Our contracts often require the design, production,
operation and maintenance of sophisticated equipment and systems and provision
of system integration services in the digital telecommunications and satellite
communications fields. A substantial portion of the digital telecommunications
and satellite communications research and development we have performed since
our inception has been funded by our customers and recorded by us as revenues.
Accordingly, the cost of performing this customer-funded research and
development is included in "Cost of Revenues" in our financial statements. Our
government contracts are generally cost-reimbursement plus profit or fixed-
price contracts. We generally recognizes revenues from our long-term government
contracts on a percentage-of-completion basis.

   Commencing in the late 1980's, we began to pursue commercial opportunities
utilizing the digital telecommunications technology we had developed and
enhanced since our inception. Commercial revenues have risen from less than 6%
of total revenues in fiscal year 1989 to approximately 36% of total revenues in
fiscal year 1999. During the first six months of fiscal year 2000, commercial
revenues from continuing operations amounted to approximately 34% of our total
revenues reported and included approximately $17.8 million in licensing fees
for certain patents and products associated with our cable modem technology.
During fiscal year 1999, commercial revenues amounted to approximately $59.9
million and included: (i) contract manufacturing revenues from our contract
manufacturing segment ($27.0 million); (ii) sales of ASICs, circuit boards and
subsystems to the telecommunications industry ($11.4 million); (iii) wireless
broadband products ($3.5 million) and (iv) other commercial systems and product
business ($18.0 million). We include in commercial revenues sales of
standardized or off-the-shelf products to any customers, including government
customers.

   On October 29, 1999, we sold to Dii Semiconductor, Inc. substantially all of
the assets of our contract manufacturing business. On November 15, 1999, we
sold to Intel Corporation substantially all of the assets of our telecom
component products business.

   Our operating results have from time to time been adversely affected by non-
recoverable cost overruns on certain fixed-price contracts, primarily fixed-
price development contracts which have included significant software and
hardware development. We have instituted additional management controls to more
closely monitor our bidding process and costs incurred on fixed-price
development contracts, however, even with these controls in place, we still
might incur losses on future fixed-price contracts or additional losses on
existing contracts. We believe that development contracts are an important
element in maintaining our technological leadership position in digital
telecommunications. As a result, we may incur losses on certain fixed-price
contracts. Such losses will be charged against results of operations in the
period when they first become known, typically near the initiation of the
contract and may have a material adverse effect on our results of operations.

Parent-Subsidiary Overview

   We have invested heavily in the development of a family of products to
deliver telephone and data services over wireless broadband links. The high
level of research and development expenses associated with the development of
the wireless broadband family has impacted our earnings results over the past
several years. During the first six months of fiscal year 2000, we delivered
initial LMDS/MMDS production units and anticipate that production revenues will
continue to increase as the demand in the broadband wireless market
materializes. In order to provide further detail as to the level of revenues,
cost of revenues, and operating expenses incurred by the base business and the
corresponding financial performance of the broadband wireless business, we
established a wholly owned subsidiary, Stanford Wireless Broadband, Inc., in
June 1998. In

                                       52
<PAGE>

addition to providing financial visibility, the establishment of the subsidiary
allows our wireless broadband customers the benefit of working with a unique
and separate entity dedicated to the development, manufacturing, sales and
support of our broadband family of products.

   The table below provides a summary of the financial performance of our base
business operations and Stanford Wireless Broadband, Inc. for the year ended
March 31, 1999.

   For fiscal year 1999, revenues for the base business segment consisted of
$105.5 million of government revenues and $29.4 million of commercial revenues.
For fiscal year 1999, revenues for Stanford Wireless Broadband, Inc. consisted
of $27.0 million from our contract manufacturing segment and $3.5 million from
our wireless broadband segment. Our wireless broadband subsidiary's operating
loss for the twelve months of fiscal year 1999 was attributable to a continued
high level of research and development in the wireless broadband family of
products, high level of costs associated with activities necessary to support
worldwide LMDS and MMDS field trials, and an operating loss associated with our
contract manufacturing segment. Operating income from the base business segment
of $15.6 million was essentially equal to the operating loss incurred by our
wireless broadband subsidiary.

   The table shown below provides a summary of the financial performance of our
base business operations and Stanford Wireless Broadband, Inc. for the six
months ended September 30, 1999.

   For the first six months of fiscal year 2000, revenues of our base business
operations consisted of $70.8 million and $17.8 million of products/services
and licensing fees, respectively. The $70.8 million of revenues realized by the
base business operations products/services consisted of $60.6 million and $10.2
million of government and commercial revenues, respectively. Operating income
for the base business operations of $22.1 million was primarily derived from
$17.8 million in licensing fees for certain patents and

                                       53
<PAGE>

products associated with our cable modem technology. Our wireless broadband
subsidiary's operating loss of $6.3 million for the first six months of fiscal
year 2000 was attributable to lower margins on the initial LMDS product
deliveries.

Business Segments Overview

   For fiscal years prior to fiscal year 2000, we classified our business into
three reportable segments: base business, wireless broadband and contract
manufacturing. On October 29, 1999, we sold to Dii Semiconductor, Inc.
substantially all of the assets of our contract manufacturing business. As a
result, information in this proxy statement relating to the first six months of
fiscal year 2000 reflects the remaining two reportable segments: base business
and wireless broadband. The base business segment primarily includes multi-year
hardware and software engineering services for data and voice communications.
The primary customer for the base business segment is the U.S. government,
however, 22% of the revenues during fiscal year 1999 were derived from the sale
of commercial products and services. During the first six months of fiscal year
2000, 32% of the base business revenues were derived from the sale of
commercial products and services, including $17.8 million of licensing fees for
certain patents and products associated with our cable modem technology. The
wireless broadband segment develops and produces hardware for broadband
wireless applications for the two-way, high-speed transmission of voice and
data. Finally, the contract manufacturing segment was in the business of
providing manufacturing services both for our products as well as products for
other companies.

(1) Operating income of $63 thousand, $5.7 million and $10.9 million in fiscal
    years 1999, 1998 and 1997 includes intra-company eliminations of profit of
    approximately $0.3 million, $0.5 million and $0.4 million, respectively,
    related to the contract manufacturing segment.

   Segment Revenues. The decrease in base business segment revenues from $134.0
million in fiscal year 1997 to $127.6 million in fiscal year 1998 was the
result of a $3.0 million decrease in commercial catalog product sales and a
$3.4 million decrease in other base business segment product and service
revenues. The increase in the base business segment revenues from $127.6
million in fiscal year 1998 to $138.8 million in fiscal year 1999 was primarily
attributable to a $16.5 million increase in other base business segment product
and service revenues offset by a $5.0 million decrease in revenues from the
sale of commercial cable and VSAT catalog products, and satellite personnel
communications system design support.

   The increases in the wireless broadband segment revenues from fiscal year
1997 to fiscal year 1998 and from fiscal year 1998 to fiscal year 1999 resulted
from increased sales associated with LMDS/MMDS field trials and deliveries of
initial production hardware during the fourth quarter of fiscal year 1999. The
decrease in the contract manufacturing segment revenues from $40.6 million in
fiscal year 1997 to $30.6 million in fiscal year 1998 was primarily the result
of an $8.6 million decrease in sales associated with the contract manufacturing
of products for other companies. Sales to external customers increased by $1.5
million from fiscal year 1998 to fiscal year 1999, however, this was offset by
a $0.9 million decrease in internal manufacturing sales.

   Segment Operating Income (Loss). The increase in operating income of the
base business segment from $15.0 million in fiscal year 1997 to $16.2 million
in fiscal year 1998 was primarily the result of higher gross margins realized
on our government and commercial revenues. Operating income decreased from
$16.2 million

                                       54
<PAGE>

in fiscal year 1998 to $15.6 million in fiscal year 1999 primarily due to
decreasing gross margins realized on government and commercial revenues. The
decrease in operating income for fiscal year 1999 was also affected by an
increase in administration and marketing expenses related to the pursuit of new
opportunities in the government market and legal fees related to patent
infringement litigation.

   The increase in operating loss of the wireless broadband segment from $4.3
million in fiscal year 1997 to $7.4 million in fiscal year 1998 was primarily
the result of increased research and development costs and increased marketing
and administrative costs. The increase in operating loss for the segment from
$7.4 million in fiscal year 1998 to $12.2 million in fiscal year 1999 was
mainly the result of increased research and development costs and lower gross
margins realized due to the increased costs associated with activities to
support worldwide LMDS and MMDS field trials.

   The contract manufacturing segment operating loss of $3.2 million in fiscal
year 1998 compared to a fiscal year 1997 operating profit of $0.2 million was
primarily attributable to the decrease in revenue of $9.9 million. The
operating loss for fiscal year 1999 was approximately the same as experienced
in fiscal year 1998.

Results of Operations

   Our revenues and results of operations are subject to fluctuation from
period to period. Factors that could cause our revenues and operating results
to vary from period to period include: underestimating costs on fixed-price
contracts, particularly for software and hardware development, timing, bidding
activity and delivery of significant contracts and orders, termination of
contracts, mix of products and systems sold, and services provided, reduced
levels of operation during the holidays which occur primarily in our third
fiscal quarter, disruptions in delivery of components or subsystems, regulatory
developments, and general economic conditions. Research and development
expenses include both research and development costs as well as bid and
proposal expenses. Bid and proposal expenses vary significantly from period to
period based on the number of proposals being prepared at any time. These
requests for proposals are not received evenly during the year or in any
predictable pattern.

</TABLE>

   Revenues. Our revenues were $167.0 million, $153.3 million, and $165.4
million in fiscal year 1997, 1998, and 1999, respectively, representing a year-
to-year decrease of 8% in fiscal year 1998 and a year-to-year increase in
fiscal year 1999 of 8%. The decrease in revenues from fiscal year 1997 to
fiscal year 1998 was

                                       55
<PAGE>

primarily the result of a decrease in revenues from our contract manufacturing
segment amounting to $8.6 million and a decrease of $5.7 million in revenues
from our base business segment. The increase in revenues from fiscal year 1998
to fiscal year 1999 was primarily attributed to a $9.8 million increase in
revenues from our base business segment.

   We expect that commercial sales in our wireless broadband segment will
increase during fiscal year 2000. In addition, as a result of strong bookings
in the base business segment in fiscal year 1999, we anticipate growth in this
segment primarily associated with sales to the government.

   Cost of Revenues. Cost of revenues were $127.4 million, $116.6 million and
$131.3 million in fiscal year 1997, 1998 and 1999, respectively. The cost of
revenues as a percentage of revenues was approximately 76% for fiscal years
1997 and 1998. The increase in cost of revenues as a percentage of revenues in
fiscal year 1999 was attributable to lower gross margins experienced by our
wireless broadband segment due to increased costs associated with worldwide
LMDS and MMDS field trials, a decrease in gross margins for the base business
segment, and increased operating costs within our contract manufacturing
segment.

   Gross Profit. Gross profit was $39.6 million, $36.6 million and $34.1
million in fiscal year 1997, 1998 and 1998, respectively. The decrease in gross
profit during fiscal year 1998 relative to fiscal year 1997 was primarily due
to a lower revenue base. The decrease in gross profit during fiscal year 1999
relative to fiscal year 1998 was primarily due to decreases in gross profits of
our base business segment and our wireless broadband segment in fiscal year
1999.

   Research and Development. Research and development expenses, including bid
and proposal expenses were $11.9 million, $13.6 million and $14.1 million in
fiscal year 1997, 1998 and 1999, respectively. We applied much of our research
and development expenditures to commercial products and initiatives in the
areas of wireless and cable broadband communications. We expect research and
development expenses in fiscal year 2000 to decrease as a percentage of
revenues compared to that experienced in fiscal year 1999, especially in the
wireless broadband segment as the LMDS/MMDS products transition from
development to full scale production. Our research and development expenses
include bid and proposal expenses associated with government contracts and
certain large commercial programs. Bid and proposal expenses comprised between
16% to 20% of the total research and development expenses during the past three
fiscal years. Bid and proposal expenditures are largely the initial advanced
technology development efforts directed toward a specific product or technical
task for which we must show technical viability. We expect an increase in bid
proposal expenses during the fiscal year 2000 resulting from increased business
opportunities in the base business segment.

   Marketing and Administrative. Marketing and administrative expenses were
$16.8 million, $17.3 million and $19.9 million in fiscal year 1997, 1998, and
1999, respectively. The increase in costs from fiscal year 1997 to fiscal year
1998 was the result of increased legal expenses primarily associated with a
patent infringement case brought by us against Broadcom Corporation in December
1996 and increased marketing expenses in pursuit of commercial opportunities.
The increased costs from fiscal year 1998 to fiscal year 1999 was the result of
additional legal expenses associated with the patent infringement litigation
which is scheduled for trial in May 1999. These legal fees associated with the
patent litigation decreased after the completion of the trial. In addition, we
experienced increased marketing expenses primarily associated with pursuit of
opportunities in the base business segment.

   Operating Income. Operating income was $10.9 million, $5.7 million, and $0.1
million for fiscal year 1997, 1998 and 1999. The decrease in operating income
from fiscal year 1997 to fiscal year 1998 was primarily the result of a
decrease in revenues, an increase in research and development and an increase
in marketing and administrative expenses. The decrease in operating income from
fiscal year 1998 to fiscal year 1999 was the result of lower overall gross
margins, an increase in marketing and administrative expenses, and an increase
in research and development expenses.

   Interest Income. Interest income was $1.3 million, $1.9 million and $1.9
million in fiscal years 1997, 1998 and 1999 respectively. In fiscal years 1998
and 1999, we increased our interest income over previous

                                       56
<PAGE>

periods as a result of maintaining a higher overall average balance in U.S.
Treasury instruments and money market accounts.

   Provision for Income Taxes. Provision for income taxes was $4.2 million,
$2.3 million and $0.6 million in fiscal years 1997, 1998 and 1999,
respectively. This represents an effective tax rate of 34.5% for fiscal year
1997, 31% for fiscal year 1998 and 31% for fiscal year 1999. The decrease in
the effective tax rate during fiscal year 1998 and 1999 compared to fiscal year
1997 results primarily from increased Research and Development (R&D) tax
credits and other state income tax credits. We anticipate that our effective
tax rate in fiscal year 2000 will be approximately the same as experienced in
fiscal year 1999 assuming continued extension of the federal R&D tax credit.

   Bookings and Backlog. Funded bookings were $168.5 million, $163.0 million
and $174.4 million in fiscal year 1997, 1998 and 1999, respectively. Government
contract bookings were $103.5 million, $102.8 million and $120.1 million during
fiscal years 1997, 1998 and 1999, respectively. Commercial contract bookings
were $65.0 million, $60.2 million and $54.3 million during fiscal years 1997,
1998 and 1999, respectively. Our backlog increased from $83.9 million at the
end of fiscal year 1997 to $93.6 million at the end of fiscal year 1998 and
further increased to $102.6 million at the end of fiscal year 1999.

 Six months ended September 30, 1999 and 1998 for continuing operations

   Revenues. Revenues from continuing operations were $91.8 million for the six
months ended September 30, 1999 and $69.7 million for the six months ended
September 30, 1998, representing an increase of 32%. Base business operations
revenues increased by 31% from $67.7 million in the first six months of fiscal
year 1999 to $88.5 million in the first six months of fiscal year 2000. The
increase in revenues for the base business operations was primarily the result
of $17.8 million in licensing fees, and the sale of commercial
telecommunication chip and board level products totaling $8.3 million for the
first six months of fiscal 2000, up from $4.7 million achieved during the first
half of the previous fiscal year. This increase was significantly offset by a
$6.0 million decrease in commercial engineering services. The wireless
broadband operations revenues increased from $2.0 million in the first six
months of fiscal 1999 to $3.3 million in the first six months of fiscal 2000
primarily due to the second quarter shipment of $1.1 million of LMDS production
hardware.

   Cost of Revenues. Cost of revenues was $60.3 million for the six months
ended September 30, 1999 and $52.9 million for the six months ended September
30, 1998. Base business operations recorded cost of revenues of $54.9 million
for the six months ended September 30, 1999 and $51.4 million for the six
months ended September 30, 1998. The base business operations increase in cost
of revenues during the first six months of fiscal year 2000 was the result of
the recognition of costs on a higher revenue base. The wireless broadband
operations increase in the cost of revenues in the first six months of fiscal
year 2000 was the result of recognition of costs on a higher revenue base and
higher cost of goods associated with initial LMDS production units.

   Research and Development. Research and development expenses, including bid
and proposal expenses were $5.6 million for the six months ended September 30,
1999 and $7.1 million for the six months ended September 30, 1998. Excluding
bid and proposal expenses, our research and development expenses applied to the
development of products such as wireless broadband communications and
telecommunication chip and board level products were $4.4 million for the six
months ended September 30, 1999 and $6.2 million for the six months ended
September 30, 1998. The decrease in research and development is mainly
attributable to a decrease in expenses within the wireless broadband operations
as the LMDS/MMDS products transition from development to production. Base
business operations research and development expenses increased from $2.0
million in the first half of fiscal year 1999 to $3.0 million in the first half
of fiscal year 2000. The increase in expenses is attributable to higher levels
of expenditures in both research and development and bid and proposals
associated with the government related opportunities in the base business
operations.

   Marketing and Administrative. Marketing and administrative expenses were
$10.1 million for the six months ended September 30, 1999 and $7.5 million for
the six months ended September 30, 1998. The increase

                                       57
<PAGE>

in cost was primarily in the base business operations as a result of increased
legal expenses associated with a patent infringement case we brought against
Broadcom Corporation and legal, consulting and other expenses related to the
merger with Newbridge and the sale of certain business operations and increased
marketing expenses in pursuit of government business. The patent infringement
case was settled during the latter part of the first quarter of fiscal 2000.
Marketing and administrative expenses for the wireless broadband operations for
the first six months of fiscal year 2000 were substantially equal to the
expenses recorded in the first six months of fiscal year 1999.

   Operating Income. Operating income was $15.8 million and $2.3 million for
the first half of fiscal 2000 and 1999, respectively. The increase in operating
income was primarily the result of recording $17.8 million in licensing fees
for certain patents associated with the base business operations' cable modem
technology, offset by increased costs in marketing and administrative expenses.

   Interest Income. Interest income for the six months of fiscal 2000 remained
unchanged at approximately $0.9 million.

   Provision for Income Taxes. For continuing operations, provision for income
taxes was $5.2 million for the first half of fiscal year 2000 and $1.0 million
for the first half of fiscal year 1999. Discontinued operations had tax
benefits of $0.4 for the first half of both fiscal years 2000 and 1999. These
represent a provisional tax rate of 31.0% for the first half of fiscal year
2000 and 1999.

   Bookings and Backlog. Funded bookings of continuing operations were $91.1
million for the six months ended September 30, 1999 and $57.3 million for the
six months ended September 30, 1998. Bookings were derived from both our
commercial operations as well as our government business operations. At the end
of the second quarter of fiscal 2000 and 1999, backlog for continuing
operations stood at $89.9 million and $66.9 million, respectively. Our bookings
and backlog are largely dependent upon the timing of funding by our government
customers.

Liquidity and Capital Resources

   Our working capital increased from $66.4 million at March 31, 1999 to $83.7
million at September 30, 1999. The increase in working capital is attributable
to cash generated from net income related to the revenues for licensing fees
for certain patents and products associated with our cable modem technology.
Licensing fees recognized during the first half of fiscal 2000 totaled $17.8
million.

   Net cash provided by operating activities for the years ended March 31,
1997, 1998 and 1999 was $18.6 million, $4.4 million and $0.3 million
respectively. The decrease from fiscal year 1997 to fiscal year 1998 is the
result of lower net income and an increase in inventories to support future
delivery of commercial products. The decrease from fiscal year 1998 to fiscal
year 1999 is the result of lower net income and an increase in receivables.
During the six months ended September 30, 1999, $4.6 million of cash was
provided by continuing operations compared to cash used in continuing operating
activities of $3.2 million during the six months ended September 30, 1998. This
increase resulted from the licensing fees collected and the decrease in
accounts receivable, partly offset by estimated tax payments and reduced
accounts payable. The decrease in accounts receivable is related to the payment
of $2.5 million against a $3.9 million secured note receivable. Accounts
receivable as of September 30, 1999 include the unpaid balance of $1.4 million
against this secured note. We expect to recover the full value of the note
receivable. Discontinued operations generated approximately $3.0 million for
the first six months of fiscal years 2000 and 1999. We used cash for the
purchase of property and equipment totaling $5.5 million, $5.9 million and $5.0
million in fiscal years 1997, 1998 and 1999, respectively. Capital expenditures
in recent years are primarily attributable to increased investments in
electronic test equipment to support both commercial and government activities.
During fiscal years 1997, 1998 and 1999 $1.6 million, $1.6 million and $0.6
million, respectively, of net cash was provided by financing activities. These
amounts represent primarily the proceeds from transactions under our stock
plans.

   We have a bank credit commitment of $15.0 million, which we have used to
augment cash flow needs and to secure term loans or standby letters of credit.
Available borrowings under this line at September 30, 1999,

                                       58
<PAGE>

were $15.0 million. Under this credit line, we must maintain certain financial
covenants. We were in compliance with all covenants throughout fiscal year 1999
and the first six months of fiscal year 2000. At September 30, 1999, our long-
term obligations (including current maturities) and capital lease obligations
totaled approximately $0.1 million. At September 30, 1999, cash and cash
equivalents of $7.8 million were held in money market accounts. In addition,
short-term investments of $29.1 million were held in U.S. government treasury
securities.

   We believe that our current cash position, funds generated from operations,
and funds available from our existing bank credit agreement, will be adequate
to meet our requirements for working capital, capital expenditure and debt
service for fiscal year 2000.

Year 2000 Issue

   The "Year 2000 Issue", also known as "Y2K", exists because many computer
programs store and process dates using only the last two digits of the year in
the date field. If not corrected, many computer applications could create
miscalculations or erroneous results causing disruptions of operations.

   We have made this issue a significant priority and has formed an
Interdisciplinary Steering Committee, which has been meeting regularly since
January 1998, dedicated to the evaluation and mitigation of any Y2K issues. The
Committee is responsible for overseeing and providing guidelines to four task
force committees whose function is to focus on specific areas of the Y2K issue,
namely products, software, customers and suppliers. Our Y2K Plan has been
presented to and approved by the Board of Directors.


   In March 1998, the Corporate Steering Committee implemented a remediation
plan to address mission-critical software (mission-critical is defined as
software or systems that can seriously impair our ability to conduct our
business) and products impacted by the Y2K issue. This plan included
Information Technology "IT" systems, and non-IT systems such as building
security systems. Our Information Technology "IT" system is compliant and
currently operating without any significant problems for our fiscal year 2000
which commenced on April 2, 1999. Other mission-critical software has been
tested or is in the process of being tested, updated, or replaced. This was the
first two phases of our plan. At this time the costs associated with these
phases have been less than $100,000, and software that has been replaced has
been done so in conjunction with planned changes not in connection with the Y2K
issue.

   The third phase of our plan involved our assessment of our products that
might be impacted by the Y2K issue. At this time 96% of our products over the
last 10 years have been reviewed. The remaining 4% are being reviewed as well
as our current products. We estimate that we will complete this review by the
end of November 1999.

   The final phase of our plan is to draft and put into effect any contingency
plan necessary to mitigate any Y2K issues. We have completed our contingency
plan for our primary IT systems and expect to complete, if necessary, any other
contingency plans during November 1999. This phase is expected to be completed
by the end of November 1999.

   The above statements describing our plans and objectives for handling the
Y2K Issue and the expected impact, involve risks and uncertainties that could
cause actual results to differ from those discussed above, thereby having an
adverse effect on our future results of operations. Uncertainties that might
cause such a difference include, but are not limited to, delays in executing
the plan or unforeseen costs associated with the implementation of the plan.
Further, even if we successfully implement the plan, there is no assurance that
we will not be adversely affected by the failure of others to become Year 2000
compliant.

Qualitative and Quantitative Disclosure About Market Risk

   Our interest income is sensitive to changes in the general level of U.S.
interest rates, particularly since the majority of our investments are in
short-term instruments. Due to the nature of short-term investments, we have
concluded that there is no material interest rate risk exposure. Therefore no
quantitative tabular disclosures are provided.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Stanford Telecommunications, Inc.:

   We have audited the accompanying consolidated balance sheets of Stanford
Telecommunications, Inc. (a Delaware Corporation) and subsidiaries as of March
31, 1999 and 1998, and the related consolidated statements of income,
stockholders' equity and cash flows for each of the three years in the period
ended March 31, 1999. These financial statements are the responsibility of the
Company'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 that our audits provide a reasonable basis
for our opinion.

   In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position
of Stanford Telecommunications, Inc. and subsidiaries as of March 31, 1999 and
1998 and the consolidated results of its operations and its consolidated cash
flows for each of the three years in the period ended March 31, 1999 in
conformity with generally accepted accounting principles.

                       STANFORD TELECOMMUNICATIONS, INC.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

   The Company. Stanford Telecommunications, Inc. (the Company), incorporated
in Delaware, designs, manufactures and markets advanced digital
telecommunication products and systems to establish or enhance communications
via satellites, terrestrial wireless and cable. The Company's technical
strengths include: system design, communication waveforms, modulation and
demodulation techniques, ASIC design Radio Frequency (RF) antennas and
downconverters, software and firmware, Asynchronous Transfer Mode (ATM) design
and advanced manufacturing techniques and processes. The Company's government
revenues are generated from U.S. government contracts where the Company may be
either the prime contractor or a subcontractor. The Company's commercial
revenues include contract manufacturing revenues, sales of integrated circuits,
circuit boards and subsystems, wireless broadband products, and development
programs. In addition to the U.S. government, the principle markets for the
Company's products include telecommunications and electronics markets primarily
located in the U.S.

   Principles of Consolidation. The consolidated financial statements include
the accounts of the Company and its wholly owned subsidiaries. All significant
intercompany accounts and transactions are eliminated in consolidation.

   Fiscal Year. The Company's fiscal year ending March 31, 1999 is comprised of
one 14-week quarter (quarter ended June 30, 1998) and three 13-week quarters,
each of which ends on the Thursday closest to the corresponding calendar
quarter end. The Company's fiscal year 1998 consisted of four 13-week quarters.
For convenience, the Company has presented its fiscal year as ending on March
31.

   Use of Estimates. The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that effect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the period.
The Company prepares and evaluateson-going cost to complete estimates in order
to monitor its project costs. These estimates form the basis for calculating
revenues and gross margins for each project under the percentage-of-completion
method of accounting. Due to uncertainties inherent in the estimation process,
estimated total costs are subject to revision on an on-going basis as
additional information becomes available. The estimates are subject to change
and actual results could be materially different from these estimates.

   Cash Equivalents. The Company considers cash equivalents to be cash in the
bank and money market accounts.

   Short-term Investments. The Company's short-term investments consist of U.S.
Treasury securities that mature at various dates within one year. The Company
classifies these securities as held-to-maturity and carries them at amortized
cost. At March 31, 1999, the fair value of the Company's investments
approximated amortized costs and, as such, unrealized holding gains were
insignificant. At March 31, 1998 unrealized holding gains totaled $270,000.

   Receivables. Accounts receivable as of March 31, 199, included a $3.9
million secured note receivable from one of the Company's customers. In January
1999, due to the customer's liquidity condition, the Company agreed to exchange
it's trade receivables for a note receivable secured by an interest in certain
of the customer's equipment with a historical cost of $13.4 million. The note
bears interest at 10% per annum and matured on May 1, 1999. The Company's
customer has paid $500,000 on May 1, 1999 and asked for an extension on the
balance of this note. The Company is considering the requested extension. The
Company provides a reserve for doubtful accounts where circumstances indicate

doubtful accounts was $533,000 and $711,000, respectively.

   Unbilled Receivables. Unbilled receivables represent differences between
billings and revenues recognized. At March 31, 1999, approximately 62% of the
unbilled receivables represent revenues recognized on fixed price contracts
under the percentage-of-completion method of accounting which exceed the
amounts that are billable according to contract terms and are expected to be
significantly collected within one year. In general, the Company is authorized
to bill between 75% to 100% of the costs expended on a contract. The remaining
portion of unbilled receivables at March 31, 1999 represents timing differences
for billings and revenues recognized on cost type contracts and differences
between actual indirect rates and government approved billing rates. The
indirect rates are not billable until approval of final indirect rates by the
respective governmental agencies. The Company has received final indirect rate
approval for charges through fiscal 1995.

   Inventories. Inventories are stated at the lower of cost (first-in, first-
out) or market. Cost includes materials, labor and related indirect expenses.
General and administrative costs are only included in inventory for government
contracts, as such costs are reimbursed by the government. Work-in-process
mainly represents costs incurred on short-term contracts. The components of
inventory are as follows:

   The Company purchases certain inventories that have long purchase lead times
and may be single sourced. Although there are a limited number of manufacturers
of these particular inventory items, management believes that other suppliers
could provide similar inventory on comparable terms. A change in suppliers,
however, could cause a delay in manufacturing and a possible loss of sales,
which may affect operating results adversely.

   Depreciation and Amortization. Depreciation and amortization are provided
over the estimated useful lives of the assets (3 to 7 years or the term of the
lease if shorter), using the straight-line method.

   Revenue Recognition. The Company principally uses the percentage-of-
completion method of accounting for contract revenues. The percentage-of-
completion method is based on total costs incurred to date compared with
estimated total costs upon completion of contracts. Certain contracts provide
for milestone billings which are recorded as revenues when the defined
milestones are met. The Company recognizes revenues for standard, off-the-shelf
products and certain commercial products upon shipment to the customer. The
Company charges all losses on contracts to cost of sales in the period when the
loss is known. The principal government agencies to which the Company sells are
the Department of Defense (DoD), NASA and the FAA. The DoD accounted

for 34%, 33%, and 33% of total revenues in 1999, 1998 and 1997, respectively.
The Company has a contract with another company whose Chief Executive Officer
is a Board member of the Company. In fiscal year 1999, the Company has
recognized $580,000 in revenues and $467,000 in cost of revenues related to
this contract

   Earnings Per Share. Basic earnings per share (EPS) is computed by dividing
net income by the weighted average number of common shares outstanding. Diluted
EPS is computed by dividing net income by the diluted weighted average number
of common shares outstanding. Diluted EPS reflects the potential dilution that
could occur upon exercise of outstanding stock options.

   The following is a summary of the calculation of the number of shares used
in calculating basic and diluted EPS:

</TABLE>

   Options to purchase 679,000, 86,000 and 75,000 weighted shares outstanding
during fiscal years 1999, 1998 and 1997, respectively were excluded from the
computation of diluted EPS because the options' exercise prices were greater
than the average market price of the Company's common stock during those years.

   Comprehensive Income. Effective April 1, 1998 the Company adopted Statement
of Financial Accounting Standards No. 130 ("SFAS 130") "Reporting Comprehensive
Income", which establishes standards for reporting and displaying comprehensive
income and its components in the financial statements. For fiscal years 1999,
1998 and 1997, the Company's net income was equal to comprehensive income as
defined in SFAS 130.

   Concentration of Credit Risk. Financial instruments which potentially
subject the Company to concentrations of credit risk consist principally of
cash equivalents, short-term investments, and trade receivables. Concentrations
of credit risk with respect to trade receivables are limited due to a balanced
mix of receivables due from the U.S. government and other customers which are
dispersed across different industries and geographic regions.

   Classification. Consistent with industry practice, assets and liabilities
relating to government long-term contracts are classified as current although a
portion of these amounts is not expected to be realized within one year.

NOTE 2. LINE OF CREDIT

   On December 18, 1998, the Company amended its bank line agreement extending
the expiration date until December 17, 1999. The Company has $15,000,000 in
credit under this line, all of which is available at March 31, 1999. Under this
line of credit the Company must maintain certain financial covenants. As of
March 31, 1999, the Company was in compliance with all such covenants.

NOTE 3. COMMITMENTS

   The Company leases its buildings and other equipment under noncancelable
operating lease agreements that expire at various dates through 2009. The
Company also leases certain office equipment under capital leases which expire
during 2004. The terms of several of the Company's leases provide for deferral
of cash rental payments over various periods. Rental expense under these
agreements is recognized on a straight-line

acquired equipment under capital leases in the amounts of $85,000, $41,000, and
$30,000, respectively.


NOTE 4. RETIREMENT PLAN

   The Company maintains a defined contribution plan covering substantially all
employees. Amounts contributed are based on a percentage of eligible employees
annual compensation. Percentages contributed equaled 3% in 1999, 3% in 1998 and
4% in 1997. The Company's contributions totaled approximately $1,645,000 in
1999, $1,403,000 in 1998, and $1,566,000 in 1997. The Plan also permits
eligible employees to make voluntary before-tax salary deferral contributions.

NOTE 6. COMMON STOCK

   In August 1998, the Board of Directors authorized a plan to repurchase the
Company's common stock in open-market transactions. The plan authorizes the
purchase of up to 1,000,000 shares of STII Common Stock. Since the
authorization of this plan, the Company repurchased 86,500 shares in open
market transactions at an average price of $10.27 per share.

   On January 29, 1997, the Company's Board of Directors declared a two-for-one
split of the Company's common stock effected in the form of a 100% stock
dividend distributed on February 28, 1997 to stockholders' of record as of
February 10, 1997. Approximately 6.4 million shares of common stock were issued
in connection with the split. The stated par value of each share was not
changed from $.01. A total of $64,000 was reclassified from the Company's paid-
in capital account to the Company's common stock account. All share and per
share amounts included in these financial statements have been restated to
retroactively reflect the stock split.

   On May 9, 1995, the Board of Directors adopted a Stockholder's Rights Plan
and declared a dividend of one Common Share Purchase Right (the "Right") for
each share of the Company's common stock outstanding on May 25, 1995. Each
Right entitles the holder thereof to purchase one share of the Company's common
stock for $30. The Rights will be exercisable if a person or group acquires 15%
or more of the Company's common stock. Upon such acquisition, each Right (other
than those held by the acquiring person or group) will

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

be exercisable for the number of shares of the Company's common stock having a
market value at that time of twice the exercise price of the Right. If the
Company subsequently enters into certain business combinations, each Right
(other than those held by the acquiring person or group) will be exercisable
for that number of shares of common stock of the other party to the business
combination having a market value of two times the exercise price of the Right.
The Rights are subject to redemption at the option of the Board of Directors at
a price of $.01 per Right. The Rights expire on May 9, 2005.

   The Company's Stock Option Plan provides for the issuance of either
incentive or non-qualified options to employees and certain non-employee
directors. Incentive options can be granted at an exercise price not less than
fair market value of the stock on the date of grant. Non-qualified options can
be granted at an exercise price not less than 85% of the fair market value of
the stock on the date of the grant. Options granted under the Plan generally
vest 25% one year after the date of grant and ratably thereafter over three
years and options generally expire ten years from the date of grant. The Plan
will expire in the year 2001.

   Information with respect to this plan is as follows:

   Pro Forma Information. The Company applies APB No.25 "Accounting for Stock
Issued to Employees" and related interpretations in accounting for the stock
compensatory plans (the Plans) described above. Accordingly, no compensation
cost has been recognized for the Plans.

   If compensation cost for the Plans had been determined consistent with SFAS
No.123 "Accounting for Stock-Based Compensation", the Company's net income and
earnings per share would have been reduced to the pro forma amounts indicated
below):

   Because the method of accounting prescribed by SFAS No.123 has not been
applied to options granted prior to April 1, 1995, and because the Black-
Scholes option valuation model was developed for traded options and requires
the input of subjective assumptions, the resulting pro forma compensation cost
may not be representative of that to be expected in future years.

   The fair value of each option grant is estimated based on the date of grant
using the Black-Scholes option pricing model with the following assumptions
used for fiscal years 1999, 1998 and 1997: risk-free interest rates of
approximately 5.3% for 1999, 6.6% for 1998 and 6.0% for 1997, dividend yields
of 0%, volatility factor of the expected market price of the Company's common
stock of 74%, and a weighted average expected life of an option of
approximately three years. The weighted average fair values of options granted
in fiscal years 1999, 1998 and 1997 respectively were $8.03, $8.33 and $7.34.

   Under an Employee Stock Purchase Plan, the Company makes offerings of its
common stock to its employees at such time and of such duration as its Board
determines. A total of 700,000 shares of common stock has been reserved for
issuance. In fiscal years 1999, 1998 and 1997, the Company has sold
140,883 shares, 90,631 shares and 66,512 shares. The weighted average fair
value of such shares for fiscal years 1999, 1998 and 1997 were $3.88, $4.88 and
$5.27 respectively. As of March 31,1999, 234,318 shares remained available for
purchase.

NOTE 7. LITIGATION AND CONTINGENCIES

   The Company is contingently liable with respect to lawsuits and other
matters which arise in the normal course of business. The Company must comply
with detailed government procurement and contracting regulations. The Company
has prepared and presented documentation and support to a customer addressing
its post-award audit recommendations. Management believes that the outcome of
such contingencies will not have a material adverse effect on the Company's
financial position or results of operations.

NOTE 8. SEGMENT REPORTING

   On March 31, 1999 Stanford Telecommunications, Inc. adopted statement of
Financial Accounting Standard (SFAS) Number 131 "Disclosures about segments of
an Enterprise and Related Information." SFAS 131 establishes standards for
public companies relating to the reporting of financial and descriptive
information about their operating segments in financial statements. Operating
segments are defined as components of an enterprise about which separate
financial information is available that is evaluated regularly

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

by the chief operating decision maker when deciding how to allocate resources
and when assessing performance. The Company's chief operating decision making
group is the Executive Staff, which is comprised of the Chief Executive Officer
and Executive Vice Presidents. The adoption of SFAS 131 did not have a material
effect on the Company's primary financial statements, but has expanded the
disclosure of segment information contained elsewhere herein.

   The Company classifies its business into three operating segments: base
business, wireless broadband and contract manufacturing. Base business consists
of multiyear hardware and software engineering services for data and voice
communications systems. Wireless broadband consists of the development and
production of products for two-way transmission of high-speed digital data and
voice. Contract manufacturing provides manufacturing services for both the
Company's products as well as products for other companies. Stanford Wireless
Broadband Inc., consists of contract manufacturing and wireless broadband
segments.

   Information as to the operation of the Company in different business
segments is set forth below based on the nature of the products and services
offered. The Company evaluates performances based on several functions of which
the primary financial measure is business segment operating income. The
accounting polices of the segments are the same as those described in the
summary of significant accounting policies within the notes within the
consolidated financial statements. Intersegment sales are generally accounted
for at cost.

   The following summarize selected financial information by segment:

pursuant to such rules and regulations, although the Company believes the
disclosures which are made are adequate to make the information presented not
misleading. Further, the condensed consolidated financial statements have been
prepared in all material respects in conformity with the standards of
accounting measurement set forth in Accounting Principles Board Opinion No. 28
and reflect, in the opinion of management, all adjustments (which include only
normal recurring adjustments) necessary to present fairly the financial
position and results of operations as of and for the periods indicated.

   It is suggested that these condensed consolidated financial statements be
read in conjunction with the financial statements and the notes thereto
included in the Stanford Telecommunications, Inc. 1999 Annual Report.

   The results of operations for the first six months of fiscal year 2000 ended
September 30, 1999 are not necessarily indicative of results to be expected for
the entire year ending March 31, 2000.

   4. Earnings (loss) per share: Basic earnings per share (EPS) of continuing
operations is computed by dividing net income of continuting operations by the
weighted average number of common shares outstanding. Diluted EPS of continuing
operations is computed by dividing net income of continuing operations by the
diluted weighted average number of common shares outstanding. Diluted EPS
reflects the potential dilution that could occur upon exercise of outstanding
stock options. Loss per share of discontinued operations is computed using the
weighted average number of common shares outstanding during the period.

   The following is a summary of the calculation of the number of shares used
in calculating basic and diluted EPS (in thousands):

   Options to purchase approximately 5,000 and 686,000 weighted shares
outstanding during the first six months of fiscal years 2000 and 1999
respectively were excluded from the computation of diluted EPS because the
options' exercise prices were greater than the average market price of the
Company's common stock during those periods.

   5. Comprehensive Income: Effective April 1, 1998 the Company adopted
Statement of Financial Accounting Standards No. 130 ("SFAS 130") "Reporting
Comprehensive Income", which establishes standards for reporting and displaying
comprehensive income and its components in the financial statements. For the
first six months of fiscal years 2000 and 1999, the Company's net income was
equal to comprehensive income as defined in SFAS 130.

   6. Segment reporting: On March 31, 1999 Stanford Telecommunications, Inc.
adopted statement of Financial Accounting Standard (SFAS) Number 131
"Disclosures about segments of an Enterprise and Related Information." SFAS 131
establishes standards for public companies relating to the reporting of
financial and descriptive information about their operating segments in
financial statements. Operating segments are defined as components of an
enterprise about which separate financial information is available that is
evaluated regularly by the chief operating decision maker when deciding how to
allocate resources and when assessing performance. The Company's chief
operating decision making group is the Executive Staff, which is comprised of
the Chief Executive Officer and Executive Vice Presidents. The adoption of SFAS
131 did not have a material effect on the company's primary financial
statements, but has expanded the disclosure of segment information contained
elsewhere herein.

   The Company classifies its business into two reportable segments: base
business and wireless broadband. The base business segment primarily includes
multi-year hardware and software engineering services for data and voice
communications. The primary customer for the base business segment is the U.S.
government, however, 30.5% of the revenues during the first six months of
fiscal year 2000 were derived from the sale of commercial products and services
including $17.8 million of licensing fees for certain patents and products
associated with the Company's cable modem technology. The wireless broadband
segment develops and produces hardware for broadband wireless applications for
the two-way, high-speed transmission of voice and data.

   Information as to the operation of the Company in different business
segments is set forth below based on the nature of the products and services
offered. The Company evaluates performances based on several functions of which
the primary financial measure is business segment operating income. The
accounting policies of the segments are the same as those described in the
summary of significant accounting policies within the notes within the
consolidated financial statements. Intersegment sales are generally accounted
for at cost.

   The following summarize selected financial information of continuing
operations by segment for the six months ended September 30, 1999 and 1998:

   7. On June 22, 1999 the Company entered into an agreement and plan of merger
with Newbridge which provided for the acquisition of the Company by Newbridge
in a tax-free, stock-for-stock exchange valued at approximately $490 million.
On November 10, 1999 the boards of directors of Newbridge and the Company
approved a renegotiated agreement and plan of merger ("Amended Merger
Agreement"), which provides for the acquisition of the Company by Newbridge in
a taxable, cash-for-stock transaction. Under the Amended Merger Agreement,
Newbridge will pay Stanford Telecom stockholders $34.22 for each share of
common stock of Stanford Telecom that they own. Newbridge will pay for the
acquisition from its existing cash balance.

   Consummation of the merger is subject to approval by the Company's
stockholders at a special meeting of Standford Telecom stockholders which is
expected to be scheduled for the second week of December 1999. The exact date
will be announced once regulatory authorities clear the proxy statement.

   Pursuant to the merger agreement, the Company has granted Newbridge an
option to acquire a non-exclusive license to the Company's wireless broadband
technology (the "Technology Option Agreement"), which option would be
exercisable at $69 million if a third party acquired control of the Company.
Also pursuant to the merger agreement, the Company has granted Newbridge an
option to purchase shares of the Company's common stock equal to 19.9% of its
issued and outstanding common stock at the time the option becomes exercisable
(the "Stock Option Agreement"). The option becomes exercisable only in
specified circumstances that could result in termination of the merger
agreement. The option has an exercise price of $35 per share.

   Certain officers and directors of the Company have entered into voting
agreements with Newbridge providing that they will vote, in their capacity as
stockholders, in favor of the adoption of the merger agreement and approval of
the merger.

   The foregoing summaries of the Amended Merger Agreement, Technology Option
Agreement, Stock Option Agreement and Voting Agreements are not complete and
are qualified in their entirety by reference to the agreements.

   8. On September 22, 1999 the Company entered into a definitive Asset
Purchase Agreement (the "ITT Agreement") with ITT Industries, Inc., an Indiana
corporation. Pursuant to the ITT Agreement, ITT will purchase substantially all
of the assets of Stanford Telecom's government business for $191 million in
cash, subject to adjustment for an increase or decrease in the net book value
of the assets and liabilities of the government business between March 31, 1999
and the closing, which is expected to take place in December 1999. Completion
of the asset purchase is subject to the satisfaction of certain conditions,
including the expiration or termination of the waiting period under the Hart-
Scott Rodino Antitrust Improvements Act of 1976, approval of the asset purchase
by the stockholders of Stanford Telecom and consummation of the pending merger
with Newbridge. The Hart-Scott-Rodino waiting period was terminated on October
15, 1999.

   9. Subsequent events--On October 29, 1999 Stanford Wireless Broadband, Inc.,
a wholly owned subsidiary of the Company, sold to Dii Semiconductor, Inc.
substantially all of the assets of Stanford Wireless Broadband's contract
manufacturing business ("MQA") and associated supply agreement with Newbridge.
Because the disposition plans were finalized before the Company's Form 10-Q was
filed for the second quarter, the Company's consolidated condensed financial
statements and notes included herein reflect MQA as a discontinued operation in
accordance with Accounting Principle Board Opinion No. 30.

<PAGE>

Merger to be consummated by filing a certificate of merger substantially in the

                              CONVERSION OF SHARES

   2.1 Conversion of Stock. Pursuant to the Merger, and without any action on
the part of the holders of any outstanding shares of capital stock or other
securities of Stel or Merger Sub:

   (a) As of the Effective Time each share of Stel Common Stock issued and
outstanding immediately prior to the Effective Time (other than shares of Stel
Common Stock to be canceled pursuant to Section 2.1(c) or as provided in
Section 2.5 with respect to shares of Stel Common Stock as to which appraisal
rights have been exercised under Delaware Law) shall be automatically converted
into the right to receive in cash without interest an amount equal to U.S.
$34.22 (the "Cash Consideration").

   (b) As of the Effective Time, each holder of a certificate or certificates
which immediately prior to the Effective Time represented outstanding shares of
Stel Common Stock shall cease to have any rights with respect thereto, except
the right to receive a cash payment equal to the number of shares represented
by such Stel Certificate multiplied by the Cash Consideration.

   (c) As of the Effective Time, each share of Stel Common Stock held of record
immediately prior to the Effective Time by Stel, Merger Sub, Newbridge or any
wholly-owned subsidiary of Stel or of Newbridge shall be canceled and
extinguished without any conversion thereof.

   (d) As of the Effective Time, each share of Common Stock, $0.01 par value,
of Merger Sub (the "Merger Sub Common Stock") issued and outstanding
immediately prior to the Effective Time shall be canceled, extinguished and
automatically converted into one validly issued, fully paid and nonassessable
share of Common Stock, $0.01 par value, of the Surviving Corporation. Each
certificate evidencing ownership of a number of shares of Merger Sub Common
Stock shall be deemed to evidence ownership of the same number of shares of
Common Stock, $0.01 par value, of the Surviving Corporation.

                                      A-2
<PAGE>

   (e) For purposes of this Agreement, the term "Subsidiary", when used with
respect to any Person, means any corporation or other organization, whether
incorporated or unincorporated, of which (A) at least a majority of the
securities or other interests having by their terms ordinary voting power to
elect a majority of the board of directors or others performing similar
functions with respect to such corporation or other organization is directly or
indirectly owned or controlled by such Person (through ownership of securities,
by contract or otherwise) or (B) such Person or any Subsidiary of such Person
is a general partner of any general partnership or a manager of any limited
liability company. For the purposes of this Agreement, the term "Person" means
any individual, group, organization, corporation, partnership, joint venture,
limited liability company, trust or entity of any kind.

   2.2 Stel Options; Stock Purchase Plan.

   (a) As of the Effective Time, Newbridge shall, to the full extent permitted
by applicable law, assume all of the stock options of Stel outstanding
immediately prior to the Effective Time under the Stel Stock Plans (as defined
below) (the "Stel Options"). For purposes of this Agreement, "Stel Stock Plans"
means Stel's 1982 Stock Option Plan, and 1991 Stock Option Plan. Each Stel
Option, whether or not exercisable at the Effective Time, shall, to the full
extent permitted by applicable law, be assumed by Newbridge in such a manner
that it shall be exercisable upon the same terms and conditions as under the
Stel Stock Plan pursuant to which it was granted and the applicable option
agreement issued thereunder; provided that:

     (i) each such option shall thereafter be exercisable for the number of
  shares of Newbridge Common Stock (rounded down to the nearest whole share)
  equal to the product obtained from multiplying the number of shares of Stel
  Common Stock covered by such option immediately prior to the Effective Time
  by a fraction (the "Option Exchange Ratio"), the numerator of which is the
  Cash Consideration and the denominator of which is the average of the daily
  averages of the high and low per share prices of Newbridge Common Stock as
  reported on the New York Stock Exchange Composite Tape on the five trading
  days ending on the second trading day immediately preceding the Stel
  Special Meeting; and

     (ii) the option price per share of Newbridge Common Stock thereafter
  shall be equal to the quotient (rounded up to the nearest whole cent)
  obtained from dividing the option price per share of Stel Common Stock
  subject to such option in effect immediately prior to the Effective Time by
  the Option Exchange Ratio.

Stel Options assumed in the manner described in this Section are referred to in
this Agreement as the "Newbridge Exchange Options". Prior to the Effective
Time, Stel shall make all adjustments provided for in the Stel Stock plan with
respect to the Stel Options to facilitate the implementation of the provisions
of this Section 2.2(a).

   (b) Notwithstanding the provisions of clause (a) above, the holders of Stel
Options which are vested or will be vested as of the Effective Time shall have
the ability to exercise such options effective as of the Effective Time on a
"cash-out" basis. Newbridge and Stel will provide a mechanism whereby, after
the Effective Time, each such Stel Option holder who has so exercised will
receive a cash payment equal to (i) the product of (A) the number of shares of
Stel Common Stock exercised and (B) the excess of the Cash Consideration over
the exercise price per share of Stel Common Stock, less (ii) any applicable
withholding or employment taxes.

   (c) All the purchase rights under Stel's 1992 Employee Stock Purchase Plan
("Stel Purchase Plan") shall terminate following the purchase of shares in
respect of the Participation Period (as defined in the Stel Purchase Plan)
beginning on or about June 30, 1999 and no Participation Period shall be
commended thereafter. All funds contributed to the Stel Purchase Plan that have
not been used to purchase shares of Stel Common Stock by the termination date
of the Stel Purchase Plan shall be returned after such termination date in
accordance with Section 8 of the Stel Purchase Plan.

                                      A-3

   2.3 Paying Agent.

   (a) At or prior to the Effective Time, Newbridge shall enter into an
agreement with a bank or trust company selected by Newbridge to act as the
paying agent for the Merger (the "Paying Agent").

   (b) At or prior to the Effective Time, Newbridge shall supply or cause to be
supplied to or for the account of the Paying Agent in trust for the benefit of
the holders of Stel Common Stock the funds necessary to make the payments
contemplated by Section 2.1. Such funds shall be invested by the Paying Agent
as directed by Newbridge in accordance with Newbridge's investment policy.

   (c) Promptly after the Effective Time, Newbridge shall mail or shall cause
to be mailed to each Holder a letter of transmittal (which shall specify that
delivery shall be effected, and risk of loss and title to the Stel Certificates
shall pass, only upon proper delivery of the Stel Certificates to the Paying
Agent) and instructions for surrender of the Stel Certificates. Upon surrender
to the Paying Agent of a Stel Certificate, together with such letter of
transmittal duly executed, the Holder shall be entitled to receive in exchange
therefor a cash payment equal to the number of shares represented by such Stel
Certificate multiplied by the Cash Consideration, and such Stel Certificate so
surrendered shall forthwith be canceled. No cash payment will be issued to a
Person who is not the registered owner of a surrendered Stel Certificate,
unless (i) the Stel Certificate so surrendered has been properly endorsed or
otherwise is in proper form for transfer, and (ii) such Person shall either (A)
pay any transfer or other tax required by reason of such issuance or (B)
establish to the satisfaction of the Surviving Corporation that such tax has
been paid or is not applicable. Until surrendered in accordance with the
provisions of this Section 2.3, from and after the Effective Time, each Stel
Certificate shall be deemed to represent the right to receive a cash payment
equal to the number of shares represented by such Stel Certificate multiplied
by the Cash Consideration. For purposes of this Agreement, "Stel Certificate"
means a certificate which immediately prior to the Effective Time represented
shares of Stel Common Stock, and "Holder" means a person who holds one or more
Stel Certificates as of the Effective Time.

   (d) Any portion of the funds supplied to the Paying Agent which remains
undistributed to the former stockholders of Stel for twelve (12) months after
the Effective Time shall be delivered to Newbridge, upon demand of Newbridge,
and any such former stockholders who have not theretofore complied with this
Section 2.3 shall thereafter look only to Newbridge (subject to abandoned
property, escheat and other similar laws) only as general creditors of
Newbridge with respect to any consideration set forth in Section 2.1 that may
be payable upon surrender of their Stel Certificates.

   (e) Notwithstanding anything to the contrary in this Agreement, none of the
Paying Agent, Newbridge, the Surviving Corporation nor any party hereto shall
be liable to any holder of shares of Stel Common Stock for any consideration
set forth in Section 2.1 delivered to a public official pursuant to any
applicable abandoned property, escheat or similar law.

   2.4 Lost, Stolen or Destroyed Certificates. In the event that any Stel
Certificates shall have been lost, stolen or destroyed, the Paying Agent shall
make in respect of such lost, stolen or destroyed Stel Certificates, upon the
making of an affidavit of that fact by the holder thereof, a cash payment equal
to the number of shares represented by such Stel Certificate multiplied by the
Cash Consideration; provided, however, that Newbridge may, in its discretion
and as a condition precedent to the payment thereof, require the owner of such
lost, stolen or destroyed Stel Certificate to deliver a bond in such sum as
Newbridge may reasonably direct as indemnity against any claim that may be made
against Newbridge or the Paying Agent with respect to the Stel Certificates
alleged to have been lost, stolen or destroyed.

   2.5 Appraisal Rights; Dissenting Shares. Any issued and outstanding shares
of Stel Common Stock held by a person who has properly demanded an appraisal
and perfected the right to dissent under Delaware Law and who has not
effectively withdrawn or lost such rights as of the Effective Time (the
"Dissenting Shares") shall not be converted into or represent the right to
receive the Cash Consideration, and the holders thereof shall be entitled only
to such rights as are granted by Delaware Law. Stel shall give Newbridge prompt

                                      A-4
<PAGE>

notice upon receipt by Stel of any such written demands for payment of the fair
value of such shares of Stel Common Stock and of withdrawals of such demands
and any other instruments provided pursuant to Delaware Law (any stockholder
duly making such demands being hereafter called a "Dissenting Stockholder").
Any payments made in respect of Dissenting Shares shall be made by Newbridge.
If any Dissenting Stockholder shall effectively withdraw or lose (through
failure to perfect or otherwise) his right to such payment at or prior to the
Effective Time, such holder's shares of Stel Common Stock shall be converted
into a right to receive the Cash Consideration in accordance with the
applicable provisions of this Agreement.

                                  ARTICLE III

                     REPRESENTATIONS AND WARRANTIES OF STEL

   Stel makes to Newbridge and Merger Sub the representations and warranties
contained in this Article III, in each case subject to the exceptions set forth
in the disclosure statement, dated as of the date hereof (the "Stel Disclosure
Statement". The Stel Disclosure Statement shall be arranged in schedules
corresponding to the numbered and lettered Sections of this Article III, and
the disclosure in any Schedule of the Stel Disclosure Statement shall qualify
only the corresponding Section of this Article III.

   3.1 Organization, Etc.

   (a) Each of Stel and its Subsidiaries is a corporation duly organized,
validly existing and in good standing under the laws of the jurisdiction of its
incorporation, and has all requisite power and authority to own, lease and
operate its properties and to carry on its business as now being conducted.
Each of Stel and its Subsidiaries is duly qualified as a foreign Person to do
business, and is in good standing, in each jurisdiction where the character of
its owned or leased properties or the nature of its activities makes such
qualification necessary, except where the failure to be so qualified or in good
standing would not, individually or in the aggregate, have a Stel Material
Adverse Effect. For the purposes of this Agreement, "Stel Material Adverse
Effect" means any change, event or effect that is materially adverse to either
(i) the business, operations or assets of Stel's wireless broadband products
division or its telecom products components division, or (ii) the general
affairs, business, operations, assets, condition (financial or otherwise) or
results of operations of Stel and its Subsidiaries taken as a whole.

   (b) Stel is not in violation of any provision of its certificate of
incorporation or bylaws. None of Stel's Subsidiaries is in violation of its
certificate of incorporation or other charter document or in material violation
of its bylaws. Schedule 3.1(b) of the Stel Disclosure Statement sets forth (i)
the full name of each Subsidiary of Stel, its capitalization and the ownership
interest of Stel and each other Person (if any) therein, (ii) the jurisdiction
in which each such Subsidiary is organized, (iii) each jurisdiction in which
Stel and each Subsidiary of Stel is qualified to do business as a foreign
Person, (iv) a brief summary of the business and material operations of each
Subsidiary of Stel, and (v) the names of the current directors and officers of
Stel and of each Subsidiary of Stel. Stel has made available to Newbridge
accurate and complete copies of the certificate of incorporation, bylaws and
any other charter documents, as currently in effect, of Stel and each of its
Subsidiaries.

   3.2 Authority Relative to This Agreement. Stel has full corporate power and
authority to (i) execute and deliver this Agreement, (ii) execute and deliver
the Stock Option Agreement, (iii) execute and deliver the Technology Option
Agreement, (iv) consummate the transactions contemplated by the Stock Option
Agreement and Technology Option Agreement, and (v) assuming the approval of the
Merger and the approval of the sale of Stel's government business assets by a
majority of the outstanding shares of Stel Common Stock at the Stel Special
Meeting or any adjournment or postponement thereof in accordance with Delaware
Law, consummate the Merger and the other transactions contemplated hereby. The
execution and delivery of this Agreement, the Stock Option Agreement and the
Technology Option Agreement, and the consummation of the Merger, the sale of
the government business assets and the other transactions contemplated hereby
and thereby, have been duly

                                      A-5
<PAGE>

and validly authorized by the unanimous vote of the board of directors of Stel,
and no other corporate proceedings on the part of Stel are necessary to
authorize this Agreement, the Stock Option Agreement and the Technology Option
Agreement or to consummate the Merger and the other transactions contemplated
hereby and thereby (other than, (a) with respect to the Merger, the approval of
the Merger by a majority of the outstanding shares of Stel Common Stock at the
Stel Special Meeting or any adjournment or postponement thereof in accordance
with the Delaware Law or (b) with respect to the sale of the government
business assets, the approval of such sale by a majority of the outstanding
shares of Stel Common Stock). Each of this Agreement, the Stock Option
Agreement and the Technology Option Agreement has been duly and validly
executed and delivered by Stel and, assuming due authorization, execution and
delivery by Newbridge and, in the case of this Agreement, by Merger Sub,
constitutes a valid and binding agreement of Stel, enforceable against Stel in
accordance with its terms, except to the extent that its enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
other laws affecting the enforcement of creditors' rights generally or by
general equitable principles.

   3.3 No Violations, Etc. No filing with or notification to, and no permit,
authorization, consent or approval of, any court, administrative agency,
commission, or other governmental or regulatory body, authority or
instrumentality ("Government Entity") is necessary on the part of Stel for the
consummation by Stel of the Merger and the other transactions contemplated
hereby and by the Stock Option Agreement and the Technology Option Agreement,
or for the exercise by Newbridge and the Surviving Corporation of full rights
to own and operate the business of Stel and its Subsidiaries as presently being
conducted, except for (i) the filing of the Certificate of Merger as required
by Delaware Law, (ii) compliance with the applicable requirements of the

the voluntary notice to be filed under Section 721 of the Defense Production
Act of 1950, as amended by Section 5021 of the Omnibus Trade and
Competitiveness Act of 1988 (the "Exon-Florio Amendment"). Neither the
execution and delivery of this Agreement, the Stock Option Agreement, and the
Technology Option Agreement nor the consummation of the Merger and the other
transactions contemplated hereby and thereby nor compliance by Stel with all of
the provisions hereof and thereof, nor the exercise by Newbridge and the
Surviving Corporation of full rights to own and operate the business of Stel
and its Subsidiaries as presently being conducted will, subject to obtaining
the approval of this Agreement by the holders of a majority of the outstanding
shares of Stel Common Stock at the Stel Special Meeting or any adjournment
thereof in accordance with Delaware Law, (i) conflict with or result in any
breach of any provision of the certificate of incorporation, bylaws or other
charter document of Stel or any of its Subsidiaries, (ii) violate any material
order, writ, injunction, decree, statute, rule or regulation applicable to
Stel, or any of its Subsidiaries, or by which any of their properties or assets
may be bound, or (iii) result in a violation or breach of, or constitute (with
or without due notice or lapse of time or both) a default under, or result in
any material change in, or give rise to any right of termination, cancellation,
acceleration, redemption or repurchase under, any of the terms, conditions or
provisions of any material note, bond, mortgage, indenture, deed of trust,
license, lease, contract, agreement or other instrument or obligation to which
Stel or any of its Subsidiaries is a party or by which any of them or any of
their properties or assets may be bound. Schedule 3.3 of the Stel Disclosure
Statement lists all consents, waivers and approvals required to be obtained in
connection with the consummation of the transactions contemplated hereby or by
the Stock Option Agreement or Technology Option Agreement under any of Stel's
or any of its Subsidiaries' notes, bonds, mortgages, indentures, deeds of
trust, licenses or leases, contracts, agreements or other instruments or
obligations the failure to obtain which would have a Stel Material Adverse
Effect.

approved and adopted this Agreement, the Stock Option Agreement and the
Technology Option Agreement (ii) determined that this Agreement is fair to and
in the best interests of the stockholders of Stel, (iii) resolved to recommend
approval of this Agreement to the stockholders of Stel, (iv) resolved that Stel
take all action necessary to exempt the execution and delivery of this
Agreement, the Stock Option Agreement and the Technology Option Agreement

                                      A-6
<PAGE>

and the consummation of the transactions contemplated hereby and thereby from
the provisions of all applicable state antitakeover statutes and regulations,
including, but not limited to, Section 203 of the Delaware Law, and (v) amended
the Stel Rights Agreement (the "Stel Rights Plan") dated as of May 9, 1995
between Stel and the First National Bank of Boston to render the rights issued
thereunder (the "Stel Rights") inapplicable to the Merger, this Agreement, the
Stock Option Agreement and the Technology Option Agreement and the other
transactions contemplated hereby, and to terminate the Stel Rights Plan as of
the Effective Time.

   3.5 Fairness Opinion. Stel has received the opinion of Ferris, Baker, Watts
dated June 21, 1999, as amended on November 10, 1999, to the effect that the
consideration to be received by the Stel stockholders in the merger is fair the
Stel stockholders from a financial point of view, and has provided a copy of
the written opinion to Newbridge.

   3.6 Capitalization.

   (a) The authorized capital stock of Stel consists of 25,000,000 shares of
Stel Common Stock. As of June 16, 1999, there were (i) 13,152,959 shares of
Stel Common Stock outstanding, and (ii) no treasury shares.

   (b) Other than the Stel Common Stock, there are no equity securities of any
class of Stel, or any securities convertible into or exercisable for any such
equity securities, issued, reserved for issuance or outstanding. Except for the
Stel Options, Stel Rights, and purchase rights under the Stel Purchase Plan
there are no warrants, options, convertible securities, calls, rights, stock
appreciation rights, preemptive rights, rights of first refusal, or agreements
or commitments of any nature obligating Stel to issue, deliver or sell, or
cause to be issued, delivered or sold, additional shares of capital stock or
other equity interests of Stel, or obligating Stel to grant, issue, extend,
accelerate the vesting of, or enter into, any such warrant, option, convertible
security, call, right, stock appreciation right, preemptive right, right of
first refusal, agreement or commitment. To the knowledge of Stel, except for
the Voting Agreements, there are no voting trusts, proxies or other agreements
or understandings with respect to the capital stock of Stel.

   (c) True and complete copies of each Stel Stock Plan and the Stel Purchase
Plan, and of the forms of all agreements and instruments relating to or issued
under each thereof, have been made available to Newbridge. Such agreements,
instruments, and forms have not been amended, modified or supplemented, and
there are no agreements to amend, modify or supplement any such agreements,
instruments or forms.

   (d) Schedule 3.6(d) of the Stel Disclosure Statement sets forth the
following information with respect to Stel Options outstanding as of June 16,
1999: the aggregate number of shares issuable thereunder, the type of option,
the grant date, the expiration date, the exercise price and the vesting
schedule. Each Stel Option was granted in accordance with the terms of the Stel
Stock Plan applicable thereto. The terms of each of the Stel Stock Plans do not
prohibit the assumption of the Stel Options as provided in Section 2.2(a).
Consummation of the Merger will accelerate vesting of all Stel Options, except
those which have been outstanding for less than one year as of the Effective
Time.

   3.7 SEC Filings.

   (a) Stel has filed with the Securities and Exchange Commission (the "SEC")
all required forms, reports, registration statements and documents required to
be filed by it with the SEC (collectively, all such forms, reports,
registration statements and documents filed since April 1, 1996 are referred to
herein as the "Stel SEC Reports"). All of the Stel SEC Reports complied as to
form, when filed, in all material respects with the applicable provisions of
the Securities Act of 1933, as amended (together with the rules and regulations
promulgated thereunder, the "Securities Act") and the Exchange Act. Accurate
and complete copies of the Stel SEC Reports have been made available to
Newbridge. As of their respective dates, the Stel SEC Reports (including all
exhibits and schedules thereto and documents incorporated by reference therein)
did not contain any untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary

                                      A-7
<PAGE>

to make the statements therein, in light of the circumstances under which they
were made, not misleading. Stel has been advised by each of its officers and
directors that each such person and such persons affiliates have complied with
all filing requirements under Section 13 and Section 16(a) of the Exchange Act.

   3.8 Financial Statements. Each of the consolidated financial statements
(including, in each case, any related notes thereto) contained in the Stel SEC
Reports (the "Stel Financial Statements"), (a) was prepared in accordance with
generally accepted accounting principles ("GAAP") applied on a consistent basis
throughout the periods involved (except as may be indicated in the notes
thereto or, in the case of unaudited interim financial statements, as may be
permitted by the SEC on Form 10-Q under the Exchange Act) and (b) fairly
presented the consolidated financial position of Stel and its Subsidiaries as
at the respective dates thereof and the consolidated results of its operations
and cash flows for the periods indicated, consistent with the books and records
of Stel, except that the unaudited interim financial statements were or are
subject to normal and recurring year-end adjustments which were not, or are not
expected to be, material in amount. The balance sheet of Stel contained in
Stel's Annual Report to Stockholders for the year ended March 31, 1999 (the
"Reference Date") is hereinafter referred to as the "Stel Balance Sheet".

   3.9 Absence of Undisclosed Liabilities. Neither Stel nor any of its
Subsidiaries has any liabilities (absolute, accrued, contingent or otherwise)
other than (i) liabilities included in the Stel Balance Sheet and the related
notes to the financial statements, (ii) normal or recurring liabilities
incurred since the Reference Date in the ordinary course of business consistent
with past practice which, individually or in the aggregate, would not be
reasonably likely to have a Stel Material Adverse Effect, and (iii) liabilities
under this Agreement, the Stock Option Agreement and the Technology Option
Agreement.

   3.10 Absence of Changes or Events. Except as contemplated by this Agreement,
since the Reference Date no Stel Material Adverse Effect has occurred and, in
addition, Stel and its Subsidiaries have not, directly or indirectly:

   (a) purchased, otherwise acquired, or agreed to purchase or otherwise
acquire, any shares of capital stock of Stel or any of its Subsidiaries, or
declared, set aside or paid any dividend or otherwise made a distribution
(whether in cash, stock or property or any combination thereof) in respect of
their capital stock (other than dividends or other distributions payable solely
to Stel or a wholly owned Subsidiary of Stel);

   (b) authorized for issuance, issued, sold, delivered, granted or issued any

   (c) All contributions to, and payments from, the Pension Plans which are

or tax under ERISA or the Code.

the trusts under any Pension or Welfare Plan or against any fiduciary of any
Pension or Welfare Plan with respect to the operation of such plan or asserting
any rights or claims to benefits under any Pension Plan or against the assets
of any trust under such plan, except for those which would not, individually or
in the aggregate, give rise to any liability which would have a Stel Material
Adverse Effect. To the best of Stel's knowledge, there are no facts which would

would not, individually or in the aggregate, have a Stel Material Adverse
Effect in the event of any such investigation, claim, suit or proceeding.

complied with the notice and continuation requirements of Section 4980B of the
Code, COBRA, Part 6 of Subtitle B of Title I of ERISA and the regulations
thereunder, except where the failure to comply would not, individually or in
the aggregate, have a Stel Material Adverse Effect.

under any Employee Benefit Plan.

   (n) Schedule 3.23(n) of the Stel Disclosure Statement lists each Foreign
Plan (as hereinafter defined). Stel and each of its Subsidiaries and each of
the Foreign Plans are in compliance with applicable laws, and all required
contributions have been made to the Foreign Plans, except where the failure to
comply or make contributions would not, individually or in the aggregate, have
a Stel Material Adverse Effect. Each of the Foreign Plans that is a funded

than the plans liabilities, as determined in accordance with applicable laws.
For purposes hereof, the term "Foreign Plan" shall mean any plan, program,
policy, arrangement or agreement maintained or contributed to by, or entered
into with, Stel or any Subsidiary with respect to employees (or former
employees) employed outside the United States to the extent the benefits

jurisdiction.

   (o) To the best of Stel's knowledge, there are no claims, suits or facts
concerning the operation or benefits of any Employee Benefit Plan other than a
Pension or Welfare Plan except for those which would not, individually or in
the aggregate, give rise to any liability which would have a Stel Material
Adverse Effect.

   (p) Each of the Employee Benefit Plans and the Foreign Plans can be

Agreement, the Stock Option Agreement and the Technology Option Agreement has
been duly and validly executed and delivered by Newbridge and Merger Sub, as

<PAGE>

Agreement, the Stock Option Agreement and the Technology Option Agreement, nor
the consummation of the Merger or the other transactions contemplated hereby or
thereby, nor compliance by Newbridge and Merger Sub with all of the provisions
hereof and thereof will (i) conflict with or result in any breach of any
provision of the certificate of incorporation, bylaws or other charter
documents of Newbridge or any Newbridge Material Subsidiary, (ii) violate any
material order, writ, injunction, decree, statute, rule or regulation
applicable to Newbridge, any Newbridge Material Subsidiary or by which any of
their properties or assets may be bound, or (iii) result in a violation or
breach of, or constitute (with or without due notice or lapse of time or both)

or any Newbridge Material Subsidiary is a party or by which any of them or any
of their properties or assets may be bound.

the Proxy Statement as it relates to Newbridge or Merger Sub, at the time the
Proxy Statement is first mailed to stockholders, at the time of the Stel
Special Meeting and at the Effective Time, shall not contain any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary in order to make the statements therein not
misleading. If at any time prior to the Effective Time any event with respect
to Newbridge or any Newbridge Material Subsidiary shall occur which is required
to be described in the Proxy Statement, such event shall be so described, and
an amendment or supplement shall be promptly filed with the SEC and, as
required by law, disseminated to the shareholders of Stel.

   4.5 Litigation. Except as set forth in the Newbridge's forms, reports,
registration statements and documents required to be filed with the SEC, there
is no Action pending or, to the knowledge of Newbridge, threatened against
Newbridge or any of its Subsidiaries, or any of their respective officers and
directors (in their capacities as such), or involving any of their assets,
before any court, or governmental or regulatory authority or body, or
arbitration tribunal, except for those Actions which, individually or in the
aggregate, would not have an Newbridge Material Adverse Effect. There is no
Action pending or, to the knowledge of Newbridge, threatened which in any
manner challenges, seeks to, or is reasonably likely to prevent, enjoin, alter
or delay the transactions anticipated by this Agreement.

   4.6 Financial Resources. As of November 10, 1999, Newbridge has the
financial resources to consummate the transactions contemplated by this
Agreement and to pay the consideration in the Merger set forth in Article II.

<PAGE>

   (m) take or agree to take, any of the actions described in Section 3.10, or
any action which would make any of its representations or warranties contained
in this Agreement untrue or incorrect or prevent it from performing or cause it
not to perform its covenants hereunder.

   5.2 No Solicitation.

   (a) From and after the date of this Agreement until the Effective Time or
termination of this Agreement pursuant to Article VIII, Stel and its
Subsidiaries will not, nor will they authorize or permit any of their
respective officers, directors, affiliates, agents or employees or any
investment banker, attorney or other advisor or representative retained by any
of them to, directly or indirectly, (i) solicit, initiate, encourage or induce
the making, submission or announcement of any Acquisition Proposal (as defined
in Section 5.2(c)), (ii) participate in any discussions or negotiations
regarding, or furnish to any person any non-public information with respect to,
or take any other action to facilitate any inquiries or the making of any
proposal that constitutes or may reasonably be expected to lead to, any
Acquisition Proposal, (iii) engage in discussions with any person with respect
to any Acquisition Proposal, (iv) approve, endorse or recommend any Acquisition
Proposal or (v) enter into any letter of intent or similar document or any
agreement or commitment contemplating or otherwise relating to any Acquisition
Transaction (as defined in Section 5.2(c)). Notwithstanding anything to the
contrary contained in this Section 5.2 or in any other provision of this
Agreement, Stel and its board of directors (i) may participate in discussions
or negotiations with or furnish non-public information to any third party that
has made an unsolicited Acquisition Proposal (a "Potential Acquiror") and/or
(ii) subject to the provisions of Section 5.4(c), may approve or accept an
unsolicited Acquisition Proposal, in each case only if the board of directors
of Stel determines in good faith (A) after receiving written advice from its
financial advisor, that such Acquisition Proposal is a Superior Proposal (as
defined in Section 5.2(d) hereof), and (B) following consultation with outside
legal counsel, that the failure to participate in such discussions or
negotiations or to furnish such information or approve or accept an Acquisition
Proposal would violate the board's fiduciary duties under applicable law. Stel
may not furnish any non-public information to a Potential Acquiror unless it is
furnished pursuant to a confidentiality agreement containing provisions at
least as favorable to Stel as the confidentiality provisions of the
Confidentiality Agreement (as defined in Section 5.3) and is simultaneously
provided to Newbridge. Without limiting the foregoing, it is understood that
any violation of the restrictions set forth in this Section 5.2(a) by any
officer, director or employee of Stel or any of its Subsidiaries or any
investment banker, attorney or other advisor or representative of Stel or any
of its Subsidiaries shall be deemed to be a breach of this Section 5.2.

   (b) In addition to the obligations of Stel set forth in Section 5.2(a), Stel
as promptly as practicable, and in any event within 24 hours, shall advise
Newbridge orally and in writing of any Acquisition Proposal or any request for
non-public information or inquiry which Stel reasonably believes would lead to
an Acquisition Proposal or to any Acquisition Transaction, the material terms
and conditions of such Acquisition Proposal, request or inquiry, and the
identity of the person or group making any such Acquisition Proposal, request
or inquiry. Stel will keep Newbridge informed as promptly as practicable in all
material respects of the status and details (including material amendments or
proposed material amendments) of any such Acquisition Proposal, request or
inquiry.

   (c) For purposes of this Agreement, "Acquisition Proposal" shall mean any
offer or proposal made by a Third Party (as defined below) relating to any
Acquisition Transaction. For purposes of this Agreement, "Acquisition
Transaction" shall mean any transaction or series of related transactions
involving: (i) any purchase from Stel or acquisition by any Person (or any
group of Persons acting in concert for the specific purpose of allowing Stel to
evade the provisions of this Section 5.2) other than Newbridge, Stel or Merger
Sub or any affiliate thereof (a "Third Party") of 15% or more of the total
interest in the total outstanding voting securities of Stel or any of its
Subsidiaries or any tender offer or exchange offer that if consummated would
result in any Third Person (or its shareholder) beneficially owning 15% or more
of the total outstanding voting securities of Stel or any of its Subsidiaries;
(ii) any merger, consolidation, business combination or similar transaction
involving Stel or any of its Subsidiaries; (iii) any sale, lease (other than in
the ordinary course of business), exchange, transfer, license (other than in
the ordinary course of business), acquisition or disposition of a material
portion of the assets of Stel (excluding the Non-core Assets); (iv) any
liquidation or dissolution of

                                      A-26
<PAGE>

Stel; or (v) the acquisition by a Third Party (or potential acquisition upon
the completion of a transaction or series of related transactions) of control
of the board of directors of Stel or the election or appointment of nominees of
a Third Party (or the ability of a Third Party to elect or appoint its
nominees) to a majority of the seats on the board of directors of Stel.

   (d) The term "Superior Proposal" means any bona fide Acquisition Proposal,
made in writing and not initiated, solicited or encouraged in violation of
Section 5.2(a) of this Agreement, on terms which the board of directors of Stel
determines in good faith to be more favorable to Stel and its stockholders or
to its stockholders than the Merger (after receiving the written advice from
Stel's financial advisor that the value of the consideration provided for in
such proposal is superior to the value of the consideration provided for in the
Merger), for which financing, to the extent required, is then committed or
which, in the good faith judgment of the board of directors of Stel, after
receiving written advice from its financial advisor, is reasonably capable of
being financed by the Potential Acquiror.

   5.3 Access to Information. From the date of this Agreement until the
Effective Time, Stel will afford Newbridge and its authorized representatives
(including counsel, environmental and other consultants, accountants, auditors
and agents) full access during normal business hours and upon reasonable notice
to all of its facilities, personnel and operations and to all books and records
of it and its Subsidiaries, will permit Newbridge and its authorized
representatives to conduct inspections as they may reasonably request and will
instruct its officers and those of its Subsidiaries to furnish such persons
with such financial and operating data and other information with respect to
its business and properties as they may from time to time request, subject to
the restrictions set forth in the Confidentiality Agreement (as defined below).
Newbridge and Merger Sub agree that each of them will treat any such
information in accordance with the Confidentiality Agreement, effective as of
March 1, 1999, between Newbridge and Stel (the "Confidentiality Agreement"),
which Confidentiality Agreement, except for the standstill provisions, shall
remain in full force and effect in accordance with its terms.

   5.4 Special Meeting; Board Recommendation.

   (a) Promptly after the date hereof, Stel will take all action necessary in
accordance with Delaware Law and its certificate of incorporation and bylaws to
convene a meeting of Stel's stockholders to consider adoption and approval of
this Agreement and approval of the Merger (the "Stel Special Meeting") to be
held as promptly as practicable, and in any event (to the extent permissible
under applicable law) within 45 days after the expiration of the 10-day waiting
period on the preliminary Proxy Statement or, if Stel receives SEC comments on
the Proxy Statement, the date that all such comments are cleared with the SEC.
Subject to Section 5.4(c), Stel will use its commercially reasonable efforts to
solicit from its stockholders proxies in favor of the adoption and approval of
this Agreement and the approval of the Merger and will take all other action
necessary or advisable to secure the vote or consent of its stockholders
required by the rules of Nasdaq or Delaware Law to obtain such approvals.
Notwithstanding anything to the contrary contained in this Agreement, Stel may
adjourn or postpone the Stel Special Meeting to the extent necessary to ensure
that any necessary supplement or amendment to the Proxy Statement is provided
to Stel's stockholders in advance of a vote on the Merger and this Agreement
or, if as of the time for which the Stel Special Meeting is originally
scheduled (as set forth in the Proxy Statement) there are insufficient shares
of Stel Common Stock represented (either in person or by proxy) to constitute a
quorum necessary to conduct the business of the Stel Special Meeting. Stel
shall ensure that the Stel Special Meeting is called, noticed, convened, held
and conducted, and that all proxies solicited by Stel in connection with the
Stel Special Meeting are solicited, in compliance with the Delaware Law, Stel's
certificate of incorporation and bylaws, the rules of Nasdaq and all other
applicable legal requirements. Stel's obligation to call, give notice of,
convene and hold the Stel Special Meeting in accordance with this Section
5.4(a) shall not be limited to or otherwise affected by the commencement,
disclosure, announcement or submission to Stel of any Acquisition Proposal, or
by any withdrawal, amendment or modification of the recommendation of the board
of directors of Stel with respect to the Merger and/or this Agreement.


                                      A-27
<PAGE>

   (b) Subject to Section 5.4(c), (i) the board of directors of Stel shall
unanimously recommend that Stel's stockholders vote in favor of and adopt and
approve this Agreement and approve the Merger at the Stel Special Meeting; (ii)
Stel shall cause the Proxy Statement to include a statement to the effect that
the board of directors of Stel has unanimously recommended that Stel's
stockholders vote in favor of and adopt and approve this Agreement and the
Merger at the Stel Special Meeting; and (iii) neither the board of directors of
Stel nor any committee thereof shall withdraw, amend or modify, or propose or
resolve to withdraw, amend or modify in a manner adverse to Newbridge, the
unanimous recommendation of the board of directors of Stel that Stel's
stockholders vote in favor of and adopt and approve this Agreement and the
Merger. For purposes of this Agreement, said recommendation of the board of
directors shall be deemed to have been modified in a manner adverse to
Newbridge if said recommendation shall no longer be unanimous, provided that,
for all purposes of this Agreement, an action by any board of directors or
committee thereof shall be unanimous if each member of such board of directors
or committee has approved such action other than (i) any such member who has
appropriately abstained from voting on such matter because of an actual or
potential conflict of interest and (ii) any such member who is unable to vote
in connection with such action as a result of death or disability.

   (c) Nothing in Section 5.4(b) shall prevent the board of directors of Stel
from withholding, withdrawing, amending or modifying its unanimous
recommendation that Stel stockholders vote in favor of and adopt and approve
this Agreement and approve the Merger if (i) a Superior Proposal is made to
Stel and is not withdrawn, (ii) Stel shall have provided written notice to
Newbridge (a "Notice of Superior Proposal") advising Newbridge that Stel has
received a Superior Proposal, specifying the material terms and conditions of
such Superior Proposal and identifying the person or entity making such
Superior Proposal, (iii) Newbridge shall not have, within five business days of
Newbridge's receipt of the Notice of Superior Proposal, made an offer that the
board of directors of Stel by a majority vote determines in its good faith
judgment (based on the written advice of its financial advisor) to be at least
as favorable to Stel's stockholders as such Superior Proposal (it being agreed
that the board of directors of Stel shall convene a meeting to consider any
such offer by Newbridge promptly following the receipt thereof), (iv) after
such board meeting, the board of directors of Stel shall have concluded in good
faith, after consultation with its outside counsel, that, in light of such
Superior Proposal, the withholding, withdrawal, amendment or modification of
such recommendation is required in order for the board of directors of Stel to
comply with its fiduciary obligations to Stel's stockholders under applicable
law and (v) Stel shall not have violated any of the restrictions set forth in
Section 5.2 or this Section 5.4(c). Subject to applicable laws, nothing
contained in this Section 5.4(c) shall limit Stel's obligation to hold and
convene the Stel Special Meeting (regardless of whether the unanimous
recommendation of the board of directors of Stel shall have been withheld,
withdrawn, amended or modified). If the Stel board has withheld, withdrawn,
amended or modified its recommendation as provided in this Section 5.4(c), Stel
shall not be required to solicit proxies from its stockholders to vote in favor
of and approve and adopt this Agreement and the Merger; provided that Stel
shall use its commercially reasonable efforts to solicit a sufficient number of
proxies (without regard to the manner in which votes are cast by those proxies)
to ensure the presence of a quorum of stockholders at the Stel Special Meeting.

   (d) Nothing contained in this Agreement shall prohibit Stel or its board of
directors from complying with the requirements of Rules 14d-9 and 14e-2(a)
promulgated under the Exchange Act.

   (e) As promptly as practicable after the execution of this Agreement, Stel
and Newbridge shall mutually prepare, and Stel shall file with the SEC, a
preliminary form of the Proxy Statement. As promptly as practicable following
receipt of SEC comments on such preliminary Proxy Statement, Newbridge and Stel
shall mutually prepare a response to such comments. Newbridge and Stel shall
use all commercially reasonable efforts to have the preliminary Proxy Statement
cleared by the SEC. Newbridge and Stel shall promptly furnish to each other all
information, and take such other actions (including without limitation using
all commercially reasonable efforts to provide any required consents of their
respective independent auditors), as may reasonably be requested in connection
with any action by any of them in connection with the preceding sentences of
this Section 5.4(e). Whenever any party learns of the occurrence of any event
which is required to be set forth in an amendment or supplement to the Proxy
Statement or any other filing made pursuant to this Section 5.4(e),

                                      A-28
<PAGE>

Newbridge or Stel, as the case may be, shall promptly inform the other of such
occurrence and cooperate in filing with the SEC or its staff and/or mailing to
stockholders of Stel such amendment or supplement.

   5.5 Commercially Reasonable Efforts. Subject to the terms and conditions
herein provided, Newbridge, Merger Sub and Stel shall use all commercially
reasonable efforts to take, or cause to be taken, all other actions and do, or
cause to be done, all other things necessary, proper or appropriate under
applicable laws and regulations to consummate and make effective the
transactions contemplated by this Agreement, including, without limitation, (a)
promptly filing Notification and Report Forms under the HSR Act with the
Federal Trade Commission (the "FTC") and the Antitrust Division of the
Department of Justice (the "Antitrust Division") and responding as promptly as
practicable to any inquiries received from the FTC or the Antitrust Division
for additional information or documentation, (b) promptly filing a notification
with the Committee on Foreign Investment in the United States ("CFIUS") under
the Exon-Florio Amendment and responding as promptly as practicable to any
inquiries received from CFIUS for additional information or documentation,
including, without limitation, taking such actions as may be required by the
U.S. Department of Defense to mitigate foreign ownership, control or influence
with respect to the performance of classified Government Contracts; (c)
obtaining all necessary governmental and private party consents, approvals or
waivers, and (d) lifting any legal bar to the Merger and the exercise of the
option granted in the Stock Option Agreement. Newbridge shall cause Merger Sub
to perform all of its obligations under this Agreement and shall not take any
action which would cause Stel to fail to perform its obligations hereunder.
Stel shall not take any action which would cause Newbridge or Merger Sub to
fail to perform their obligations hereunder.

   5.6 Public Announcements. Before issuing any press release or otherwise
making any public statement with respect to the Merger or any of the other
transactions contemplated hereby, Newbridge, Merger Sub and Stel agree to
consult with each other as to its form and substance, and agree not to issue
any such press release or general communication to employees or make any public
statement prior to obtaining the consent of the other (which shall not be
unreasonably withheld or delayed), except as may be required by applicable law
or by the rules and regulations of or listing agreement with the NYSE, the
Nasdaq, The Toronto Stock Exchange or as may otherwise be required by of the
NYSE, Nasdaq, the SEC or Canadian securities authorities.

   5.7 Notification of Certain Matters. Each of Stel and Newbridge shall
promptly notify the other party of the occurrence or non-occurrence of any
event the respective occurrence or non-occurrence of which would be likely to
cause any condition to the obligations of the notifying party to effect the
Merger not to be fulfilled. Each of Stel and Newbridge shall also give prompt
notice to the other of any communication from any Person alleging that the
consent of such Person is or may be required in connection with the Merger or
other transactions contemplated hereby.

   5.8 Indemnification.

   (a) The certificate of incorporation and bylaws of the Surviving Corporation
shall contain, and Newbridge shall cause the Surviving Corporation to fulfill
and honor, the provisions with respect to indemnification set forth in the
certificate of incorporation and bylaws of Stel as of the date of this
Agreement, which provisions shall not be amended, repealed or otherwise
modified for a period of six years from the Effective Time in any manner that
would adversely affect the rights thereunder of individuals who, immediately
prior to the Effective Time, were directors and officers of Stel, unless such
modification is required by law.

   (b) After the Effective Time the Surviving Corporation, to the fullest
extent permitted under applicable law or under the Surviving Corporation's
certificate of incorporation or bylaws, shall hold harmless, (i) each present
director or officer of Stel and each of its Subsidiaries, and (ii) each person
identified on Schedule 5.8(b) as presently serving at the request of Stel or
any Subsidiary of Stel as a director, officer, trustee, partner, fiduciary,
employee or agent of another corporation, partnership, joint venture, trust,
pension or other employee

                                      A-29
<PAGE>

benefit plan or enterprise (collectively, the "Indemnified Parties") against
any costs or expenses (including attorney's fees), judgments, fines, losses,
claims, damages, liabilities and amounts paid in settlement in connection with
any claim, action, suit, proceeding or investigation, whether civil, criminal,
administrative or investigative, to the extent arising out of or pertaining to
any action or omission in his or her capacity as a director or officer of Stel
arising out of or pertaining to the transactions contemplated by this Agreement
for a period of six years after the date hereof. In the event of any such
claim, action, suit, proceeding or investigation (whether arising before or
after the Effective Time), (i) any counsel retained by the Indemnified Parties
for any period after the Effective Time must be reasonably satisfactory to
Newbridge, (ii) after the Effective Time, Newbridge shall cause the Surviving
Corporation to pay the reasonable fees and expenses of such counsel, promptly
after statements therefor are received and (iii) Newbridge shall cause the
Surviving Corporation to cooperate in the defense of any such matter; provided,
however, that neither Newbridge nor the Surviving Corporation shall be liable
for any settlement effected without its written consent (which consent shall
not be unreasonably withheld); and provided, further, that, in the event that
any claim or claims for indemnification are asserted or made within such six-
year period, all rights to indemnification in respect of any such claim or
claims shall continue until the disposition of any and all such claims; and
provided, further, that nothing in this Section 5.8 shall impair any rights or
obligations of any present or former directors or officers of Stel. The
Indemnified Parties as a group may retain only one law firm (in addition to
local counsel) to represent them with respect to any single action unless there
is, under applicable standards of professional conduct, a conflict on any
significant issue between the positions of any two or more Indemnified Parties.
In the event Newbridge or the Surviving Corporation or any of their respective
successors or assigns (i) consolidates with or merges into any other Person and
shall not be the continuing or surviving corporation or entity of such
consolidation or merger, or (ii) transfers or conveys all or substantially all
of its properties and assets to any Person, then, and in each such case, to the
extent necessary to effectuate the purposes of this Section 5.8, proper
provision shall be made so that the successors and assigns of Newbridge and the
Surviving Corporation assume the obligations of such party set forth in this
Section 5.8 and none of the actions described in clause (i) or (ii) shall be
taken until such provision is made.

   (c) For a period of six years after the Effective Time, Newbridge shall or
shall cause the Surviving Corporation to maintain in effect, if available,
directors' and officers' liability insurance covering those persons who are
currently covered by Stel's directors' and officers' liability insurance policy
on terms comparable to those applicable under the policy of directors' and
officers' liability insurance currently maintained by Stel; provided, however,
that in no event shall Newbridge or the Surviving Corporation be required to
expend in excess of 150% of the annual premium currently paid by Stel for such
coverage, and that if the annual premiums of such insurance coverage exceed
such amount, the Surviving Corporation shall be obligated instead to obtain a
policy with the greatest coverage available for a cost not exceeding such
amount.

   (d) Newbridge shall cause the Surviving Corporation to perform its
obligations under this Section 5.8 and shall, in addition, guarantee, as co-
obligor with the Surviving Corporation, the performance of such obligations by
the Surviving Corporation.

   5.9 [Reserved].

   5.10 Listings. Newbridge shall use commercially reasonable efforts to list
on the NYSE, upon official notice of issuance, the shares of Newbridge Common
Stock to be issued upon exercise of the Newbridge Exchange Options. Newbridge
shall use commercially reasonable efforts to list on the Toronto Stock
Exchange, subject to the satisfaction of customary conditions, the shares of
Newbridge Common Stock issued upon exercise of the Newbridge Exchange Options.

   5.11 Resignation of Directors and Officers. Prior to the Effective Time,
Stel shall deliver to Newbridge the resignations of such directors and officers

                                  TERMINATION

   8.1 Termination. This Agreement may be terminated at any time prior to the
Effective Time, whether before or after the requisite approval of the
stockholders of Stel:

   (a) by mutual written consent duly authorized by the boards of directors of
Newbridge, Stel and Merger Sub;

   (b) by either Stel or Newbridge if the Merger shall not have been
consummated by January 31, 2000 (the "End Date"), which date may be extended by
mutual consent of the parties hereto; provided, however, that the right to
terminate this Agreement under this Section 8.1(b) shall not be available to
any party whose action or failure to act has proximately contributed to the
failure of the Merger to occur on or before such date and such action or
failure to act constitutes a material breach of this Agreement;

executive order shall have been enacted, entered or promulgated prohibiting the
consummation of the Merger substantially on the terms contemplated hereby or
(ii) a court of competent jurisdiction or other Government Entity shall have

prohibiting the Merger substantially on the terms contemplated hereby, and such

Agreement pursuant to this Section 8.1(c) unless such party shall have used its
reasonable efforts to remove such order, decree, ruling or injunction;

available to Stel where (i) Stel shall have breached in any material respect
its obligations under this Agreement in any manner that shall have proximately
contributed to the failure to obtain such stockholder approval (it being
specifically understood that a withholding, withdrawal, amendment or
modification of the board of directors recommendation to Stel stockholders to
vote in favor of and approve and adopt this Agreement and approve the Merger in

Agreement) or (ii) such failure was caused by a breach of any Voting Agreement

   (e) by Newbridge if a Stel Triggering Event (as defined below) shall have
occurred;

   (f) [Reserved].

written notice of such breach or breaches and such breach or breaches shall not
have been so cured within 30 days after delivery to Newbridge of such written
notice; provided, further, that Stel shall not be permitted to terminate this
Agreement pursuant to this Section 8.3(g) if Stel shall have breached in any
material respect its obligations under this Agreement in any manner that shall
have proximately caused such breach or breaches of Newbridge; or

   (h) by Newbridge, if there exists a breach or breaches of any representation
or warranty of Stel contained in this Agreement such that the Closing condition
set forth in Section 7.2(a) or 7.2(b) would not be satisfied; provided,
however, that if such breach or breaches are capable of being cured prior to
the Effective Time such

                                      A-34
<PAGE>

that such condition would be satisfied, then Newbridge shall not be permitted
to terminate this Agreement pursuant to this Section 8.1(h) unless Newbridge
shall have delivered to Stel written notice of such breach or breaches and such
breach or breaches shall not have been so cured within 30 days after delivery
to Stel of such written notice; provided, further that Newbridge shall not be
permitted to terminate this Agreement pursuant to this Section 8.2(h) if
Newbridge shall have breached in any material respect its obligations under
this Agreement in any manner that shall have proximately caused such breach or
breaches of Stel.

recommendation be reaffirmed; (iv) the board of directors of Stel or any
committee thereof shall have failed to reject any Acquisition Proposal; (v)
Stel shall have entered into any letter or intent or similar document or any
agreement or commitment contemplating or otherwise relating to an Acquisition
Proposal; (vi) subject to Stel's ability to adjourn or postpone a meeting
pursuant to the third sentence of Section 5.4(a), Stel shall have failed to
hold the Stel Special Meeting as promptly as practicable and in any event (to
the extent permissible under applicable law) within 45 days after the
expiration of the 10-day waiting period on the preliminary Proxy Statement or,
if Stel receives SEC comments on the Proxy Statement, the date that all such
comments are cleared with the SEC; (vii) a tender or exchange offer relating to
securities of Stel shall have been commenced by a Person unaffiliated with

disclosing that the board of directors of Stel recommends rejection of such
tender or exchange offer; or (viii) Stel shall have breached any of its
obligations under Section 5.2 of this Agreement.

   8.2 Notice of Termination; Effect of Termination. Any termination of this
Agreement under Section 8.1 will be effective immediately upon the delivery of

the last sentence of Section 5.3, this Section 8.2, Section 8.3, Sections 9.4,
9.5, 9.6, 9.10, 9.11 and 9.12, each of which shall survive the termination of
this Agreement, and (ii) nothing herein shall relieve any party from liability

with their terms.

   8.3 Fees and Expenses.

   (a) General. Except as set forth in this Section 8.3, all fees and expenses
incurred in connection with this Agreement and the transactions contemplated
hereby shall be paid by the party incurring such expenses whether or not the
Merger is consummated; provided, however, that Newbridge and Stel shall share
equally all fees and expenses, other than attorneys' and accountants' fees and
expenses, incurred in relation to the printing and filing (with the SEC) of the
Proxy Statement (including any preliminary materials related thereto) and any
registration statement (including financial statements and exhibits) and any
amendments or supplements thereto.

   (b) Stel Payments.

     (i) In the event that this Agreement is terminated by Newbridge pursuant
  to Section 8.1(e), Stel shall promptly, but in no event later than ten
  business days after the date of such termination, pay Newbridge a
  nonrefundable fee equal to U.S. $25 million in immediately available funds
  (the "Termination Fee").

                                      A-35
<PAGE>

     (ii) In the event that this Agreement is terminated by Newbridge or
  Stel, as applicable, pursuant to Section 8.1 (b) or (d), (A) Stel shall pay
  Newbridge the Termination Fee only if following the date hereof and prior
  to the termination of this Agreement, a Third Party has publicly announced
  an Acquisition Proposal and within 12 months following the termination of
  this Agreement, Stel executes with a Third Party an agreement providing for
  an Acquisition Transaction or an Acquisition Transaction has been
  consummated and (B) such payment shall be made promptly, but in no event
  later than ten business days after the execution of such agreement.

     (iii) In the event that this Agreement is terminated by Newbridge or
  Stel pursuant to Section 8.1(d) and Stel is not required to pay Newbridge
  the Termination Fee, Stel shall reimburse Newbridge for all documented
  expenses incurred by Newbridge in connection with this Agreement, the Stock
  Option Agreement, the Technology Option Agreement and the transactions
  contemplated hereby (the "Newbridge Expenses") in immediately available
  funds not later than ten business days after the first anniversary of the
  execution of this Agreement.

     (iv) In the event that this Agreement is terminated by Newbridge
  pursuant to Section 8.1(h) because the Closing condition set forth in
  Section 7.2(b) is not satisfied, Stel shall promptly, but in no event later
  than ten business days after the date of such termination, reimburse
  Newbridge for the Newbridge Expenses in immediately available funds.

     (v) Stel acknowledges that the agreements contained in this Section
  8.3(b) are an integral part of the transactions contemplated by this
  Agreement, and that, without these agreements, Newbridge would not enter
  into this Agreement; accordingly, if Stel fails to pay in a timely manner
  the amounts due pursuant to this Section 8.3(b), and, in order to obtain
  such payment, Newbridge makes a claim that results in a judgment against
  Stel for the amounts set forth in this Section 8.3(b), Stel shall pay to
  Newbridge its reasonable costs and expenses (including reasonable
  attorneys' fees and expenses) in connection with such suit, together with
  interest on the amounts set forth in this Section 8.3(b) at the prime rate
  of The Chase Manhattan Bank in effect on the date such payment was required
  to be made. Payment of the fees described in this Section 8.3(b) shall not
  be in lieu of damages incurred in the event of breach of this Agreement.

on the one hand, or Stel, on the other hand, to comply with any obligation,
covenant, agreement or condition herein may be waived by Stel or Newbridge or
Merger Sub, respectively, only by a written instrument signed by the party
granting such waiver, but such waiver or failure to insist upon strict
compliance with such obligation, covenant, agreement or condition shall not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure. Whenever this Agreement requires or permits consent by or on behalf of
any party hereto, such consent shall be given in writing in a manner consistent
with the requirements for a waiver of compliance as set forth in this Section
9.2.

Acquisition Proposal, as defined in the Merger Agreement (any of the events
specified in clauses (i) or (ii) of this sentence being referred to herein as
an "Exercise Event").

   (b) In the event Newbridge wishes to exercise the Option, Newbridge shall
deliver to Stel a written notice (each an "Exercise Notice") specifying the
total number of Option Shares it wishes to acquire and a closing date and time
prior to the expiration of the Option for the purchase of such Option Shares (a
"Closing"). The Exercise Notice may be withdrawn by Newbridge at any time prior
to a Closing. Unless an Exercise Notice is withdrawn, the Closing shall occur
on the specified date at the principal offices of Stel.

   (c) The Option shall expire upon the earliest of (i) the Effective Time,
(ii) the termination of the Merger Agreement pursuant to any of Section 8.1(a),
8.1(c), 8.1(f), 8.1(g) or 8.1(h) thereof, (iii) the termination of the Merger
Agreement pursuant to either Section 8.1(b) or 8.1(d) thereof, if prior thereto
no Exercise Event shall have occurred, or (iv) 18 months following the
termination of the Merger Agreement under any other circumstances; provided,
however, that if the Option cannot be exercised by reason of any applicable
statute, rule, regulation or government order, or because any applicable
waiting period related to issuance of the Option Shares under the HSR Act shall
not have expired or been terminated, then the Option shall not expire until the
tenth business day after such impediment to exercise shall have been removed or
shall have become final and not subject to appeal.

                                      C-1

   (d) If Newbridge receives an amount pursuant to Section 8.3(b)(i) or (ii) of
the Merger Agreement which, when aggregated with proceeds received by Newbridge
in connection with any sales or other dispositions of Option Shares and any
dividends received by Newbridge declared on Option Shares, is equal to more
than the sum of (i) $25,000,000 plus (ii) the Exercise Price multiplied by the
number of Stel Shares purchased by Newbridge pursuant to the Option, then all
proceeds to Newbridge in excess of such sum shall be remitted by Newbridge to
Stel.

   3. Conditions to Closing.

   The obligation of Stel to issue Option Shares to Newbridge hereunder is
subject to the conditions that (a) all filings and declarations required to be
made, all authorizations, consents, orders and approvals required to be
obtained, and all waiting periods required to expire or be terminated, pursuant
to a requirement of any Government Entity or applicable law (including, without
limitation the HSR Act) shall have been made or obtained or shall have expired
or been terminated, in each case in connection with the exercise of the Option
hereunder; and (b) no preliminary or permanent injunction or other order by any
court of competent jurisdiction prohibiting or otherwise restraining such
issuance shall be in effect. It is understood and agreed that at any time
during which the Option is exercisable, the parties will use their respective
reasonable efforts to satisfy all conditions to Closing, so that a Closing may
take place as promptly as practicable, and in any event, prior to consummation
of a tender or exchange offer for shares of Stel capital stock.

   4. Closing.

   At each Closing, (a) Stel shall deliver to Newbridge a single certificate in
definitive form representing the number of Stel Shares designated by Newbridge
in its Exercise Notice, such certificate to be registered in the name of
Newbridge and to bear the legend set forth in Section 10 hereof, against
delivery of (b) payment by Newbridge to Stel of the aggregate purchase price
for the Stel Shares so designated and being purchased by wire transfer or
delivery of a certified check or bank check.

   5. Representations and Warranties of Stel.

   Stel represents and warrants to Newbridge that:

   (a) Stel is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware and has full corporate power
and authority to execute and deliver this Agreement and to carry out its
obligations hereunder;

   (b) the execution and delivery of this Agreement by Stel and consummation by
Stel of the transactions contemplated hereby have been duly and validly
authorized by all necessary corporate action on the part of Stel, and no other
corporate proceedings on the part of Stel are necessary to authorize this
Agreement or any of the transactions contemplated hereby;

   (c) this Agreement has been duly and validly executed and delivered by Stel,
constitutes a legal, valid and binding obligation of Stel and, assuming this
Agreement constitutes a legal, valid and binding obligation of Newbridge, is
enforceable against Stel in accordance with its terms, except as enforceability
may be limited by bankruptcy and other laws affecting the rights and remedies
of creditors generally and general principles of equity;

   (d) except for any filings required under the HSR Act, Stel has taken all
necessary corporate and other action to authorize and reserve for issuance and
to permit it to issue upon exercise of the Option, and at all times from the
date hereof until the termination of the Option will have reserved for
issuance, a sufficient number of unissued Stel Shares for Newbridge to exercise
the Option in full and will take all necessary corporate or other action to
authorize and reserve for issuance all additional Stel Shares or other
securities which may be issuable pursuant to Section 9 upon exercise of the
Option, all of which, upon their issuance and delivery in accordance with the
terms of this Agreement, will be validly issued, fully paid and nonassessable;

                                      C-2
<PAGE>

   (e) upon delivery of the Stel Shares and any other securities to Newbridge
upon exercise of the Option, Newbridge will acquire such Stel Shares or other
securities free and clear of all material claims, liens, charges, encumbrances
and security interests of any kind or nature whatsoever, excluding those
imposed by Newbridge;

   (f) the execution and delivery of this Agreement by Stel do not, and the
performance of this Agreement by Stel will not, (i) conflict with the
certificate of incorporation or bylaws of Stel, (ii) violate any order
applicable to Stel or any of its Subsidiaries or by which they or any of their
property is bound or affected, or (iii) result in any breach of or constitute a
default (or an event which with notice or lapse of time or both would become a
default) under, or give rise to any right of termination, amendment,
acceleration or cancellation of, or result in the creation of a lien or
encumbrance on any of the property or assets of Stel or any of its Subsidiaries
pursuant to, any contract or agreement to which Stel or any of its Subsidiaries
is a party or by which Stel or any of its Subsidiaries or any of their property
is bound or affected;

   (g) the execution and delivery of this Agreement by Stel does not, and the
performance of this Agreement by Stel will not, require any consent, approval,
authorization or permit of, or filing with, or notification to, any Government
Entity, except pursuant to the HSR Act; and

   (h) the board of directors of Stel has resolved to render the rights issued
under the Stel Rights Plan inapplicable to this Agreement and the transactions
contemplated hereby.

   6. Certain Rights.

   (a) At the request of and upon notice by Newbridge (the "Put Notice"), if at
any time during the period during which the Option is exercisable pursuant to
Section 2, Stel executes with a Third Party an agreement providing for an
Acquisition Transaction or an Acquisition Transaction has been consummated (the
"Purchase Period"):

   (i) Stel (or any successor entity thereof) shall purchase from Newbridge the
Option, to the extent not previously exercised, at a price equal to the
difference between the "Market/Tender Offer Price" for Stel Shares as of the
date Newbridge gives notice of its intent to exercise its rights under this
Section 6(a) and the Exercise Price, multiplied by the number of Stel Shares
purchasable pursuant to the Option. For purposes of this Agreement,
"Market/Tender Offer Price" means the higher of (A) the highest price per share
offered as of such date pursuant to any Acquisition Proposal which was made
prior to such date and not terminated or withdrawn as of such date and (B) the
highest closing sale price of Stel Shares on the Nasdaq National Market
("Nasdaq") during the twenty (20) trading days ending on the trading day
immediately preceding such date. For purposes of determining the highest price
offered pursuant to any Acquisition Proposal which involves consideration other
than cash, the value of such consideration shall be equal to the higher of (x)
if securities of the proponent of the same class as such consideration are
traded on any national securities exchange or by any registered securities
association, a value based on the closing sale price for such securities on
their principal trading market on such date and (y) the value ascribed to such
consideration by the proponent of such Acquisition Proposal, or if no such
value is ascribed, a value determined in good faith by the board of directors
of Stel.

   (ii) Stel (or any successor entity thereof) shall purchase the Option
Shares, if any, acquired by Newbridge at a price equal to (A) the Exercise
Price paid by Newbridge for such Stel Shares plus (B) (1) the difference
between the Market/Tender Offer Price and such Exercise Price multiplied by (2)
the number of Stel Shares so purchased.

   (iii) Notwithstanding subparagraphs (i) and (ii) above, pursuant to this
Section 6(a), Stel shall not be required to pay Newbridge in excess of an
aggregate of (A) $25,000,000 plus (B) the Exercise Price paid by Newbridge for
Stel Shares acquired pursuant to the exercise of the Option minus (C) any
amounts paid or to be paid to Newbridge by Stel pursuant to Section 8.3(b)(i)
or (ii) of the Merger Agreement.

   (b) In the event Newbridge exercises its rights under Section 6(a), Stel
shall, within ten business days after Newbridge delivers notice pursuant to
Section 6(a), pay the required amount to Newbridge in immediately available
funds. Newbridge shall thereupon surrender to Stel the Option and the
certificates evidencing the Stel

                                      C-3
<PAGE>

Shares purchased by Newbridge pursuant thereto, and shall represent and warrant
that such shares are then free and clear of all claims, liens, charges,
encumbrances and security interests of any kind or nature whatsoever, other
than those imposed by Stel.

   (c) If Newbridge shall have acquired Option Shares pursuant to exercise of
the Option and neither (i) any Acquisition Transaction with respect to Stel
shall have been consummated at any time after the date of this Agreement and
prior to 18 months after the termination of the Merger Agreement nor (ii) shall
Stel have entered into an agreement with respect to such an Acquisition
Transaction, which agreement remains in effect at the end of such 18 months,
then, at any time after the earlier of (A) 18 months after the termination of
the Merger Agreement and (B) the day prior to the effectiveness of a
registration statement filed by Stel pursuant to Section 7 below, and prior to
the date 24 months following the termination of Merger Agreement, Stel may
require Newbridge, upon delivery to Newbridge of written notice, to sell to
Stel any Stel Shares held by Newbridge as of the day that is ten business days
after the date of such notice ("Call Shares"), up to a number of Call Shares
equal to the number of Option Shares acquired by Newbridge in connection with
such Exercise Date. The per share purchase price for such sale (the "Stel Call
Price") shall be equal to the Exercise Price less any dividends paid on the
Call Shares to be purchased. The closing of any sale of Call Shares shall take
place at the principal offices of Stel at a time and on a date designated by
Stel in the aforementioned notice to Newbridge, which date shall be no more
than 20 and no less than 12 business days from the date of such notice. The
Stel Call Price shall be paid in immediately available funds.

   7. Registration Rights.

   (a) Following the termination of the Merger Agreement, Newbridge and its
permitted assigns or successors (a "Holder") may by written notice (a
"Registration Notice") to Stel (the "Registrant") request the Registrant to
register under the Securities Act all or any part of the shares of Registrant
acquired by such Holder pursuant to this Agreement (the "Registrable
Securities"), in order to permit the sale or other disposition of such shares
pursuant to a Permitted Offering (as defined below); provided, however that any
such Registration Notice must relate to a number of shares equal to at least 1%
of the outstanding shares of Common Stock of the Registrant on a fully diluted
basis and that any rights to require registration hereunder shall terminate
with respect to any shares that may be sold pursuant to Rule 144(k) under the
Securities Act. For purposes of this Agreement, a "Permitted Offering" means a
bona fide firm commitment underwritten public offering in which the Holder and
the underwriters shall effect as wide a distribution of such Registrable
Securities as is reasonably practicable and shall use all reasonable efforts to
prevent any person or group from purchasing through such offering shares
representing more than 1% of the outstanding shares of Common Stock of the
Registrant on a fully diluted basis. The Registration Notice shall include a
certificate executed by the Holder and its proposed managing underwriter, which
underwriter shall be an investment banking firm of nationally recognized
standing (the "Manager"), stating that (i) the Holder and the Manager have a
good faith intention to commence a Permitted Offering, and (ii) the Manager in
good faith believes that, based on the then prevailing market conditions, it
will be able to sell the Registrable Securities at a per share price equal to
at least 80% of the per share average of the closing sale prices of the
Registrant's Common Stock on Nasdaq for the 20 trading days immediately
preceding the date of the Registration Notice. The Registrant shall thereupon
have the option, exercisable by written notice delivered to the Holder within
10 business days after the receipt of the Registration Notice, irrevocably to
agree to purchase all or any part of the Registrable Securities for cash at a
price (the "Option Price") equal to the product of (i) the number of
Registrable Securities so purchased and (ii) the per share average of the
closing sale prices of the Registrant's Common Stock on Nasdaq for the
20 trading days immediately preceding the date of the Registration Notice. Any
such purchase of Registrable Securities by the Registrant hereunder shall take
place at a closing to be held at the principal executive offices of the
Registrant or its counsel at any reasonable date and time designated by the
Registrant in such notice within 10 business days after delivery of such
notice. The payment for the shares to be purchased shall be made by delivery at
the time of such closing of the Option Price in immediately available funds.

   (b) If the Registrant does not elect to exercise its option to purchase
pursuant to Section 7(a) with respect to all Registrable Securities, the
Registrant shall use all reasonable efforts to effect, as promptly as
practicable, the registration under the Securities Act of the unpurchased
Registrable Securities requested to be registered in

                                      C-4
<PAGE>

the Registration Notice; provided, however, that (i) the Holder shall not be
entitled to more than an aggregate of two effective registration statements
hereunder and (ii) the Registrant will not be required to file any such
registration statement during any period of time (not to exceed 40 days after a
Registration Notice in the case of clause (A) below or 90 days after a
Registration Notice in the case of clauses (B) and (C) below) when: (A) the
Registrant is in possession of material non-public information which it
reasonably believes would be detrimental to be disclosed at such time and, in
the written opinion of counsel to the Registrant, such information would have
to be disclosed if a registration statement were filed at that time; (B) the
Registrant is required under the Securities Act to include audited financial
statements for any period in such registration statement and such financial
statements are not yet available for inclusion in such registration statement;
or (C) the Registrant determines, in its reasonable judgment, that such
registration would interfere with any financing, acquisition or other material
transaction involving such Registrant. If consummation of the sale of any
Registrable Securities pursuant to a registration hereunder does not occur
within 180 days after the filing with the SEC of the initial registration
statement therefor, the provisions of this Section 7 shall again be applicable
to any proposed registration, it being understood that the Holder shall not be
entitled to more than an aggregate of two effective registration statements
hereunder. The Registrant shall use all reasonable efforts to cause any
Registrable Securities registered pursuant to this Section 7 to be qualified
for sale under the securities or blue sky laws of such jurisdictions as the
Holder may reasonably request, and shall continue such registration or
qualification in effect in such jurisdictions; provided, however, that the
Registrant shall not be required to qualify to do business in, or consent to
general service of process in, any jurisdiction by reason of this provision.

   (c) The registration rights set forth in this Section 7 are subject to the
condition that the Holder shall provide the Registrant with such information
with respect to such Holder's Registrable Securities, the plan for distribution
thereof, and such other information with respect to the Holder as, in the
reasonable judgment of counsel for the Registrant, is necessary to enable the
Registrant to include in a registration statement all material facts required
to be disclosed with respect to a registration thereunder.

   (d) A registration effected under this Section 7 shall be effected at the
Registrant's expense, except for underwriting discounts and commissions and the
fees and expenses of counsel to the Holder, and the Registrant shall provide to
the underwriters such documentation (including certificates, opinions of
counsel and "comfort" letters from auditors) as are customary in connection
with underwritten public offerings and as such underwriters may reasonably
require. In connection with any registration, the Holder and the Registrant
agree to enter into an underwriting agreement reasonably acceptable to each
such party, in form and substance customary for transactions of this type with
the underwriters participating in such offering.

   8. Indemnification.

   (a) The Registrant will indemnify the Holder, each of its directors and
officers and each person who controls the Holder within the meaning of Section
15 of the Securities Act, and each underwriter of the Registrant's securities,
with respect to any registration, qualification or compliance which has been
effected pursuant to this Agreement, against all expenses, claims, losses,
damages or liabilities (or actions in respect thereof), including any of the
foregoing incurred in settlement of any litigation, commenced or threatened,
arising out of or based on any untrue statement (or alleged untrue statement)
of a material fact contained in any registration statement, prospectus,
offering circular or other document, or any amendment or supplement thereto,
incident to any such registration, qualification or compliance, or based on any
omission (or alleged omission) to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading, or any violation by the
Registrant of any rule or regulation promulgated under the Securities Act
applicable to the Registrant in connection with any such registration,
qualification or compliance. The Registrant will reimburse the Holder and each
of its directors and officers and each person who controls the Holder within
the meaning of Section 15 of the Securities Act, and each underwriter for any
legal or any other expenses reasonably incurred in connection with
investigating, preparing or defending any such claim, loss, damage, liability
or action, provided that the Registrant will not be liable in any such case
only to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission or alleged untrue

                                      C-5
<PAGE>

statement or omission, made in reliance upon and in conformity with written
information furnished to the Registrant by such Holder or director or officer
or controlling person or underwriter seeking indemnification.

   (b) The Holder will indemnify the Registrant, each of its directors and
officers and each underwriter of the Registrant's securities covered by such
registration statement and each person who controls the Registrant within the
meaning of Section 15 of the Securities Act, against all expenses, claims,
losses, damages and liabilities (or actions in respect thereof), including any
of the foregoing incurred in settlement of any litigation, commenced or
threatened, arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any such registration statement,
prospectus, offering circular or other document, or any amendment or supplement
thereto, incident to any such registration, qualification or compliance, or
based on any omission (or alleged omission) to state therein a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances in which they were made, not misleading, or any
violation by the Holder of any rule or regulation promulgated under the
Securities Act applicable to the Holder in connection with any such
registration, qualification or compliance. The Holder will reimburse the
Registrant and each of its directors and officers and each person who controls
the Registrant within the meaning of Section 15 of the Securities Act, and each
underwriter for any legal or any other expenses reasonably incurred in
connection with investigating, preparing or defending any such claim, loss,
damage, liability or action, in each case to the extent, but only to the
extent, that any such claim, loss, damage, liability or expense arises out of
or is based on any untrue statement or omission or alleged untrue statement or
omission made in reliance upon and in conformity with written information
furnished to the Registrant by such Holder or director or officer or
controlling person or underwriter for use therein, provided that in no event
shall any indemnity under this Section 8(b) exceed the gross proceeds of the
offering received by the Holder.

   (c) Each party entitled to indemnification under this Section 8 (an
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified
Party has actual knowledge of any claim as to which indemnity may be sought,
and shall permit the Indemnifying Party to assume the defense of any such claim
or any litigation resulting therefrom. Counsel for the Indemnifying Party, who
shall conduct the defense of such claim or litigation, shall be approved by the
Indemnified Party (whose approval shall not unreasonably be withheld), and the
Indemnified Party may participate in such defense at such party's expense;
provided, however, that the Indemnifying Party shall pay such expense if
representation of the Indemnified Party by counsel retained by the Indemnifying
Party would be inappropriate due to actual or potential differing interests
between the Indemnified Party and any other party represented by such counsel
in such proceeding. The failure of any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations
under this Section 8(c) unless the failure to give such notice is materially
prejudicial to an Indemnifying Party's ability to defend such action. No
Indemnifying Party, in the defense of any such claim or litigation shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement which does not include the claimant's or
plaintiff's unconditional release of Indemnified Party from all liability in
respect to such claim or litigation. No Indemnifying Party shall be required to
indemnify any Indemnified Party with respect to any settlement entered into
without such Indemnifying Party's prior consent (which shall not be
unreasonably withheld).

   (d) If the indemnification provided for in this Section 8 is held by a court
of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any expenses, claims, losses, damages and liabilities referred to
therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified
Party hereunder, shall contribute to the amount paid or payable by such
indemnified party as a result of such any expenses, claims, losses, damages and
liabilities in such proportion as is appropriate to reflect the relative fault
of the Indemnifying Party on the one hand and of the Indemnified Party on the
other in connection with the statements or omissions that resulted in such any
expenses, claims, losses, damages and liabilities as well as any other relevant
equitable considerations. The relative fault of the Indemnifying Party and of
the Indemnified Party shall be determined by reference to, among other things,
whether the untrue (or alleged untrue statement) of a material fact or the
omission (or alleged omission) to state a material fact relates to information
supplied

                                      C-6
<PAGE>

by the Indemnifying Party or by the Indemnified Party and the parties' relative
intent, knowledge, access to information, and opportunity to correct or prevent
such statement or omission.

   9. Adjustment Upon Changes in Capitalization: Rights Plans.

   (a) If any change shall occur in the Stel Shares by reason of stock
dividends, stock splits, reverse stock splits, mergers (other than the Merger),
recapitalizations, combinations, exchanges of shares and the like, then (i) the
type and number of shares or securities subject to the Option, and (ii) the
Exercise Price shall be adjusted appropriately, and proper provision shall be
made in the agreements governing such transaction so that Newbridge shall
receive, upon exercise of the Option, the number and class of shares or other
securities or property that Newbridge would have received in respect of the
Stel Shares if the Option had been exercised immediately prior to such change
or the record date therefor, as applicable.

   (b) Prior to such time as the Option is terminated, and at any time after
the Option is exercised (in whole or in part), (i) Stel shall not take any
action to reverse or amend the resolution referred to in Section 5(h) of this
Agreement and (ii) Stel shall not amend, (nor permit the amendment of) its
Rights Agreement nor adopt (nor permit the adoption of) a new stockholders
rights plan that contains provisions for the distribution or exercise of rights
thereunder as a result of Newbridge, or any affiliate or transferee, being the
beneficial owner of Stel Shares by virtue of the Option being exercisable or
having been exercised or as a result of beneficially owning shares issuable in
respect of the Option Shares.

   10. Restrictive Legend.

   Each certificate representing Option Shares issued to Newbridge hereunder
shall include a legend in substantially the following form:

     THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
  UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY BE REOFFERED OR SOLD
  ONLY IF SO REGISTERED OR IF AN EXEMPTION FROM SUCH REGISTRATION IS
  AVAILABLE.

   Certificates representing shares sold in a registered public offering
pursuant to Section 7 shall not be required to bear the legend set forth in
Section 10.

   11. Listing and HSR Filing.

   Stel, upon the request of Newbridge, shall promptly file an application to
list the Stel Shares to be acquired upon exercise of the Option on Nasdaq and
shall use all reasonable efforts to obtain approval of such listing as soon as
practicable. Promptly after a request by Newbridge, Stel shall file
Notification and Report Forms under the HSR Act with the FTC and the Antitrust
Division. Stel shall use all reasonable efforts to respond as promptly as
practicable to any inquiries received from the FTC or the Antitrust Division
for additional information or documentation.

   12. Assignment; Binding Effect.

   Neither this Agreement nor the Option created hereunder nor any right,
interest or obligation hereunder shall be assigned by either party without the
prior written consent of the other. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
permitted assigns. This Agreement is not intended to confer any rights or
remedies upon any Person other than the parties hereto. Any shares sold by a
party in compliance with the provisions of Section 7 hereof shall, upon
consummation of such sale, be free of the restrictions imposed with respect to
such shares by this Agreement and any transferee of such shares shall not be
entitled the rights of the transferor under this Agreement.

                                      C-7
<PAGE>

   13. Specific Performance.

   Each of the parties hereto recognizes and acknowledges that a breach by it
of any covenants or agreements contained in this Agreement will cause the other
party to sustain damages for which it would not have an adequate remedy at law
for money, damages. Therefore, in the event of any such breach, the aggrieved
party shall be entitled to the remedy of specific performance of such covenants
and agreements and injunctive and other equitable relief in addition to any
other remedy to which it may be entitled, at law or in equity.

   14. Entire Agreement.

   This Agreement and the Merger Agreement, including the exhibits thereto and
the documents and instruments referred to therein, embody the entire agreement
and understanding of the parties hereto in respect of the subject matter
contained herein. There are no representations, promises, warranties,
covenants, or undertakings, other than those expressly set forth or referred to
herein and therein.

   15. Further Assurances.

   Each party will execute and deliver all such further documents and
instruments and take all such further action as may be necessary in order to
consummate the transactions contemplated hereby.

   16. Severability.

   If any term, provision, covenant, or restriction of this Agreement is held
by a court of competent jurisdiction or a federal or state regulatory agency to
be invalid, void, or unenforceable, the other terms, provisions, covenants, and
restrictions of this Agreement shall remain in full force and effect and shall
not be affected, impaired, or invalidated. If for any reason such court or
regulatory agency determines that the Option does not permit Newbridge to
acquire, or does not require Stel to repurchase, the full number of Option
Shares provided herein (as adjusted pursuant to Section 9), it is the express
intention of Stel to allow Newbridge to acquire, or to require Stel to
repurchase, such lesser number of shares as may be permissible without any
amendment or modification hereof.

   17. Notices.

   All notices and other communications hereunder shall be in writing and shall
be delivered personally by overnight courier or similar means or sent by
facsimile with written confirmation of receipt, to the parties at the addresses

               [Letterhead of Ferris, Baker Watts, Incorporated]

                                                               November 10, 1999

The Board of Directors
Stanford Telecommunications, Inc.
1221 Crossman Avenue
Sunnyvale, CA 94089

Gentlemen:

   Stanford Telecommunications, Inc. ("Stanford" or the "Company") has
requested a review of the proposed transaction (the "Transaction") involving
the proposed acquisition of Stanford by Newbridge Networks Corporation
("Newbridge"). Specifically, you have requested a review of the financial
consideration to be offered to the Company's stockholders as consideration for
their shares in the Transaction. We were retained by the Board of Directors and
commenced our investigation of the Transaction on June 7, 1998.

   Pursuant to the Transaction, Newbridge will pay to Stanford shareholders an
amount equal to $34.22 in cash.

   In connection with the opinion, we have reviewed, among other things, (i)
the proposed Transaction, (ii) the letter of intent dated May 24, 1999, (iii)
the draft of the Amended and Restated Agreement and Plan of Merger dated June
10, 1999, amended as of August 20, 1999 and amended and restated as of November
10, 1999, (iv) historical operating results of Stanford, (v) internally
prepared projections for Stanford, and (vi) the historical trading performance
of the Company's stock. We have held discussions with the members of the
management of the Company regarding the past and current business operations as
well as the future prospects of the Company. We have reviewed industry specific
data regarding the valuation of publicly traded companies in the digital
communications market as well as other such information as we considered
appropriate.

   Currently, we make a market in the Company's common stock and we
periodically prepare research reports on the Company. Ferris, Baker Watts,
Incorporated, its clients, its officers or its employees, in the normal course
of business, may have a position in the common stock of the Company.

   In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of all financial and other information reviewed by us for purposes
of this opinion whether publicly available or provided to us by the Company or
representatives of the Company, and we have not assumed any responsibility for
independent verification of such information. We express no opinion as to the
consideration to be received by holders of shares who may perfect dissenters'
statutory fair appraisal remedies, if available. Based upon the foregoing and
based upon other such matters that we considered relevant, it is our opinion
that the consideration to be received by the stockholders of the Company as a
result of the Transaction is fair from a financial point of view as of the date
hereof.

   Our opinion is necessarily based upon economic, market and other conditions
as in effect on, and the information made available to us as of the date
hereof. Our opinion is directed to the Board of Directors of the Company and
does not constitute a recommendation to any stockholder of the Company as to
how the stockholder should vote at the stockholder's meeting held in connection
with the Transaction. It is understood that subsequent developments may affect
the conclusions reached in this opinion and that we do not have any obligation
to update, revise or reaffirm this opinion.

                                        Very truly yours,

                                        /s/ Ferris, Baker Watts, Incorporated

                                                                      APPENDIX E

                        DELAWARE GENERAL CORPORATION LAW

SECTION 262. APPRAISAL RIGHTS

   (a) Any stockholder of a corporation of this State who holds shares of stock
on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to (S) 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of the stockholder's shares of stock under the circumstances
described in subsections (b) and (c) of this section. As used in this section,
the word "stockholder" means a holder of record of stock in a stock corporation
and also a member of record of a nonstock corporation; the words "stock" and
"share" mean and include what is ordinarily meant by those words and also
membership or membership interest of a member of a nonstock corporation; and
the words "depository receipt" mean a receipt or other instrument issued by a
depository representing an interest in one or more shares, or fractions
thereof, solely of stock of a corporation, which stock is deposited with the
depository.

   (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to (S) 251 (other than a merger effected pursuant to (S)
251(g) of this title), (S) 252, (S) 254, (S) 257, (S) 258, (S) 263 or (S) 264
of this title:

     (1) Provided, however, that no appraisal rights under this section shall
  be available for the shares of any class or series of stock, which stock,
  or depository receipts in respect thereof, at the record date fixed to
  determine the stockholders entitled to receive notice of and to vote at the
  meeting of stockholders to act upon the agreement of merger or
  consolidation, were either (i) listed on a national securities exchange or
  designated as a national market system security on an interdealer quotation
  system by the National Association of Securities Dealers, Inc. or (ii) held
  of record by more than 2,000 holders; and further provided that no
  appraisal rights shall be available for any shares of stock of the
  constituent corporation surviving a merger if the merger did not require
  for its approval the vote of the stockholders of the surviving corporation
  as provided in subsection (f) of (S) 251 of this title.

     (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
  under this section shall be available for the shares of any class or series
  of stock of a constituent corporation if the holders thereof are required
  by the terms of an agreement of merger or consolidation pursuant to (S)(S)
  251, 252, 254, 257, 258, 263 and 264 of this title to accept for such stock
  anything except:

       a. Shares of stock of the corporation surviving or resulting from
    such merger or consolidation, or depository receipts in respect
    thereof;

       b. Shares of stock of any other corporation, or depository receipts
    in respect thereof, which shares of stock or depository receipts at the
    effective date of the merger or consolidation will be either listed on
    a national securities exchange or designated as a national market
    system security on an interdealer quotation system by the National
    Association of Securities Dealers, Inc. or held of record by more than
    2,000 holders;

       c. Cash in lieu of fractional shares or fractional depository
    receipts described in the foregoing subparagraphs a. and b. of this
    paragraph; or

       d. Any combination of the shares of stock, depository receipts and
    cash in lieu of fractional shares or fractional depository receipts
    described in the foregoing subparagraphs a. b. and c. of this
    paragraph.

     (3) In the event all of the stock of a subsidiary Delaware corporation
  party to a merger effected under (S) 253 of this title is not owned by the
  parent corporation immediately prior to the merger, appraisal rights shall
  be available for the shares of the subsidiary Delaware corporation.

                                      E-1
<PAGE>

   (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets
of the corporation. If the certificate of incorporation contains such a
provision, the procedures of this section, including those set forth in
subsections (d) and (e) of this section, shall apply as nearly as is
practicable.

   (d) Appraisal rights shall be perfected as follows:

     (1) If a proposed merger or consolidation for which appraisal rights are
  provided under this section is to be submitted for approval at a meeting of
  stockholders, the corporation, not less than 20 days prior to the meeting,
  shall notify each of its stockholders who was such on the record date for
  such meeting with respect to shares for which appraisal rights are
  available pursuant to subsections (b) or (c) hereof that appraisal rights
  are available for any or all of the shares of the constituent corporations,
  and shall include in such notice a copy of this section. Each stockholder
  electing to demand the appraisal of such stockholder's shares shall deliver
  to the corporation, before the taking of the vote on the merger or
  consolidation, a written demand for appraisal of such stockholder's shares.
  Such demand will be sufficient if it reasonably informs the corporation of
  the identity of the stockholder and that the stockholder intends thereby to
  demand the appraisal of such stockholder's shares. A proxy or vote against
  the merger or consolidation shall not constitute such a demand. A
  stockholder electing to take such action must do so by a separate written
  demand as herein provided. Within 10 days after the effective date of such
  merger or consolidation, the surviving or resulting corporation shall
  notify each stockholder of each constituent corporation who has complied
  with this subsection and has not voted in favor of or consented to the
  merger or consolidation of the date that the merger or consolidation has
  become effective; or

     (2) If the merger or consolidation was approved pursuant to (S) 228 or
  (S) 253 of this title, each constituent corporation, either before the
  effective date of the merger or consolidation or within ten days
  thereafter, shall notify each of the holders of any class or series of
  stock of such constituent corporation who are entitled to appraisal rights
  of the approval of the merger or consolidation and that appraisal rights
  are available for any or all shares of such class or series of stock of
  such constituent corporation, and shall include in such notice a copy of
  this section; provided that, if the notice is given on or after the
  effective date of the merger or consolidation, such notice shall be given
  by the surviving or resulting corporation to all such holders of any class
  or series of stock of a constituent corporation that are entitled to
  appraisal rights. Such notice may, and, if given on or after the effective
  date of the merger or consolidation, shall, also notify such stockholder's
  of the effective date of the merger or consolidation. Any stockholder
  entitled to appraisal rights may, within 20 days after the date of mailing
  of such notice, demand in writing from the surviving or resulting
  corporation the appraisal of such holder's shares. Such demand will be
  sufficient if it reasonably informs the corporation of the identity of the
  stockholder and that the stockholder intends thereby to demand the
  appraisal of such holder's shares. If such notice did not notify
  stockholders of the effective date of the merger or consolidation, either
  (i) each such constituent corporation shall send a second notice before the
  effective date of the merger or consolidation notifying each of the holders
  of any class or series of stock of such constituent corporation that are
  entitled to appraisal rights of the effective date of the merger or
  consolidation or (ii) the surviving or resulting corporation shall send
  such a second notice to all such holders on or within 10 days after such
  effective date; provided, however, that if such second notice is sent more
  than 20 days following the sending of the first notice, such second notice
  need only be sent to each stockholder who is entitled to appraisal rights
  and who has demanded appraisal of such holder's shares in accordance with
  this subsection. An affidavit of the secretary or assistant secretary or of
  the transfer agent of the corporation that is required to give either
  notice that such notice has been given shall, in the absence of fraud, be
  prima facie evidence of the facts stated therein. For purposes of
  determining the stockholders entitled to receive either notice, each
  constituent corporation may fix, in advance, a record date that shall be
  not more than 10 days prior to the date the notice is given, provided, that
  if the notice is given on or after the effective date of the merger or
  consolidation, the record date shall be such effective date. If no record
  date is fixed and the notice is given

                                      E-2
<PAGE>

  prior to the effective date, the record date shall be the close of business
  on the day next preceding the day on which the notice is given.

   (e) Within 120 days after the effective date of the merger or consolidation,
the surviving or resulting corporation or any stockholder who has complied with
subsections (a) and (d) hereof and who is otherwise entitled to appraisal
rights, may file a petition in the Court of Chancery demanding a determination
of the value of the stock of all such stockholder's. Notwithstanding the
foregoing, at any time within 60 days after the effective date of the merger or
consolidation, any stockholder shall have the right to withdraw such
stockholder's demand for appraisal and to accept the terms offered upon the
merger or consolidation. Within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10
days after such stockholder's written request for such a statement is received
by the surviving or resulting corporation or within 10 days after expiration of
the period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

   (f) Upon the filing of any such petition by a stockholder, service of a copy
thereof shall be made upon the surviving or resulting corporation, which shall
within 120 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the
addresses therein stated. Such notice shall also be given by 1 or more
publications at least 1 week before the day of the hearing, in a newspaper of
general circulation published in the City of Wilmington, Delaware or such
publication as the Court deems advisable. The forms of the notices by mail and
by publication shall be approved by the Court, and the costs thereof shall be
borne by the surviving or resulting corporation.

   (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled
to appraisal rights. The Court may require the stockholders who have demanded
an appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as
to such stockholder.

   (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any
element of value arising from the accomplishment or expectation of the merger
or consolidation, together with a fair rate of interest, if any, to be paid
upon the amount determined to be the fair value. In determining such fair
value, the Court shall take into account all relevant factors. In determining
the fair rate of interest, the Court may consider all relevant factors,
including the rate of interest which the surviving or resulting corporation
would have had to pay to borrow money during the pendency of the proceeding.
Upon application by the surviving or resulting corporation or by any
stockholder entitled to participate in the appraisal proceeding, the Court may,
in its discretion, permit discovery or other pretrial proceedings and may
proceed to trial upon the appraisal prior to the final determination of the
stockholder entitled to an appraisal. Any stockholder whose name appears on the
list filed by the surviving or resulting corporation pursuant to subsection (f)
of this section and who has submitted such stockholder's certificates of stock
to the Register in Chancery, if such is required, may participate fully in all
proceedings until it is finally determined that such stockholder is not
entitled to appraisal rights under this section.


                                      E-3
<PAGE>

   (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to
the stockholders entitled thereto. Interest may be simple or compound, as the
Court may direct. Payment shall be so made to each such stockholder, in the
case of holders of uncertificated stock forthwith, and the case of holders of
shares represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

   (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

   (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation,
either within 60 days after the effective date of the merger or consolidation
as provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the
Court of Chancery shall be dismissed as to any stockholder without the approval
of the Court, and such approval may be conditioned upon such terms as the Court
deems just.

   (l) The shares of the surviving or resulting corporation to which the shares
of such objecting stockholders would have been converted had they assented to
the merger or consolidation shall have the status of authorized and unissued
shares of the surviving or resulting corporation.
