(1) Each share of Motorola common stock is accompanied by a right to purchase
    Junior Participating Preferred Stock, Series B of Motorola. Prior to the
    occurrence of certain events, none of which has occurred as of this date,
    the rights will not be exercisable or evidenced separately from the common
    stock.
(2) Represents the maximum number of shares of Motorola common stock that may
    be issued to former C-Port Corporation stockholders pursuant to the
    proposed merger described herein, giving effect to the exercise of
    outstanding options, warrants or other rights to purchase C-Port common
    stock and assuming an exchange ratio of 0.1022485 of a share of Motorola
    common stock for each share of C-Port common stock pursuant to the merger
    described herein. On February 29, 2000, Motorola declared, subject to
    approval by its stockholders, a 3-for-1 common stock split in the form of a
    stock dividend payable on June 1, 2000 to holders of Motorola common stock
    of record as of May 15, 2000. The applicable exchange ratio terms of the
    merger agreement will automatically adjust in certain circumstances to
    reflect the Motorola stock split. To the extent the proposed merger is
    completed after May 15, 2000, this registration statement will be deemed to
    cover, pursuant to Rule 416 under the Securities Act of 1933, as amended,
    8,723,586 shares of Motorola common stock (including the associated stock
    purchase rights), which includes the 5,815,724 maximum additional shares of
    Motorola common stock that may be issued to former C-Port stockholders
    pursuant to the merger agreement to give effect to the Motorola stock
    split.
(3) Estimated solely for the purpose of calculating the registration fee
    required by Section 6(b) of the Securities Act, and calculated pursuant to
    Rule 457(f) under the Securities Act. C-Port is a privately held
    corporation and there is no market for its securities. Pursuant to Rule
    457(f)(2) under the Securities Act of 1933, as amended, the proposed
    maximum aggregate offering price is based upon the book value of the
    securities of C-Port being acquired in the proposed merger, which is
    $9,686,238, computed as of the latest practicable date prior to the date of
    filing this registration statement.
(4) Calculated by multiplying .000264 by the proposed maximum aggregate
    offering price.

   The registrant hereby amends this registration statement on such date or
dates as may be necessary to delay its effective date until the registrant
shall file a further amendment which specifically states that this registration
statement shall thereafter become effective in accordance with Section 8(a) of
the Securities Act of 1933, as amended, or until this registration statement
shall become effective on such date as the Securities and Exchange Commission,
acting pursuant to said Section 8(a), may determine.

                  Subject to Completion, Dated March 24, 2000

                               C-Port Corporation
                                One High Street
                       North Andover, Massachusetts 01845

                              [           ], 2000

Dear Stockholders:

  You are cordially invited to attend a special meeting of stockholders of C-
Port Corporation which we will hold at [         ].m., local time, on
[          ], [          ], 2000, at the offices of Hale and Dorr LLP, 60 State
Street, Boston, Massachusetts 02109.

  C-Port Corporation has signed a merger agreement with Motorola, Inc. If the
merger is completed, C-Port will become a wholly owned subsidiary of Motorola.

  At the special meeting, we will ask you to vote on the merger agreement and
the merger of C-Port and Motorola. Your board of directors has unanimously
approved the merger agreement and the merger and unanimously recommends that
you approve and adopt the merger agreement and the merger at the special
meeting.

  If C-Port's stockholders approve the merger agreement and the merger, then
each of your C-Port common shares will be exchanged in the merger for 0.1022485
of a share of Motorola common stock. If the merger occurs after May 15, 2000,
the record date for the three-for-one stock split of Motorola's common stock
approved by the Motorola board of directors on February 29, 2000, the 0.1022485
exchange ratio will automatically adjust under the merger agreement to
0.3067455 to reflect the stock split. Please note that the exchange ratio will
not be adjusted in the event of any increase or decrease in the market price of
Motorola common stock. You should therefore obtain a current market quotation
for Motorola common stock before voting on the merger.

  Approximately 10% of the Motorola common stock that you would otherwise be
entitled to receive in the merger will be deposited in an escrow account and
may be used to compensate Motorola in the event that it is entitled to
indemnification under the merger agreement. Shares of Motorola common stock
subject to issuance under options granted under C-Port's 1997 stock incentive
plan will not be included in the escrow account. To the extent that some or all
of the escrowed shares are not required to indemnify Motorola, the escrowed
shares will be distributed within five business days following the first
anniversary of the merger. Motorola common stock is listed on the New York
Stock Exchange under the trading symbol "MOT" and on [        ], 2000, Motorola
common stock closed at $[    ] per share. You will receive cash instead of any
fractional share of Motorola common stock which you would otherwise receive in
the merger.

  In order to complete the merger, C-Port's charter requires that the merger
agreement and the merger be approved by:

  . holders of a majority of the outstanding shares of C-Port common stock and
    C-Port Series A, Series B and Series C preferred stock, voting together as
    a single class; and

  . holders of at least fifty-five percent (55%) of the outstanding shares of
    C-Port Series A, Series B and Series C preferred stock, voting together as
    a single class.
- -----
  Neither the Securities and Exchange Commission nor any state securities
commission has approved or disapproved of this transaction or the Motorola
common stock to be issued in the merger, or determined that this proxy
statement/prospectus is accurate or complete. Any person who tells you
otherwise is committing a crime.
<PAGE>

   I, together with other stockholders of C-Port holding in the aggregate
approximately 55.7% of the outstanding C-Port common stock and preferred stock,
voting together as a single class, and approximately 69.8% of the outstanding
C-Port preferred stock, voting together as a single class, have agreed to vote
all of our shares in favor of the approval of the merger agreement and the
merger. Consequently, approval of the merger agreement and the merger is
assured.

   C-Port stockholders who properly preserve their rights are entitled to an
appraisal under Delaware law if the merger is completed.

   Only stockholders who hold shares of C-Port stock at the close of business
on [           ], 2000, the record date for the special meeting, will be
entitled to vote at the special meeting of C-Port stockholders.

   You should consider the matters discussed under "Risk Factors" commencing on
page 14 of the enclosed proxy statement/prospectus before voting. Please review
carefully the entire proxy statement/prospectus.

   It is important that your shares be represented and voted at the special
meeting, whether or not you are able to attend personally. If you do not return
your proxy card, the effect will be a vote against the merger. You are
therefore urged to complete, sign, date and return the enclosed proxy card
promptly in the accompanying envelope, which requires no postage if mailed in
the United States. You are, of course, welcome to attend the meeting and vote
in person, even if you have previously returned your proxy card.

   I look forward to your support.

                                          Sincerely,

                                          Laurence G. Walker

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

   Q: What is the proposed transaction?

   A: A wholly owned subsidiary of Motorola, Inc. will merge into C-Port
Corporation. As a result, C-Port will become a wholly owned subsidiary of
Motorola, and C-Port stockholders will exchange their C-Port shares for shares
of Motorola common stock.

   Q: Why are the companies proposing the merger?

   A: Motorola's Semiconductor Products Sector offers multiple DigitalDNA(TM)
solutions which enable its customers to create new business opportunities in a
variety of markets. Part of the challenge of the network environment is to
provide upgrade solutions through software rather than frequent rewiring and
equipment upgrades. Motorola and C-Port believe that the combination of
Motorola's host and integrated communications processors with C-Port's network
processor will enable Motorola to offer a scalable family of solutions for the
intelligent programmable functions inside network equipment manufacturers'
products.

   Q: What will I receive in the merger?

   A: Each of your C-Port common shares will be exchanged in the merger for
0.1022485 of a share of Motorola common stock. If the merger occurs after May
15, 2000, the record date for the three-for-one stock split of Motorola's
common stock approved by the Motorola board of directors on February 29, 2000,
the 0.1022485 exchange ratio will automatically adjust under the merger
agreement to 0.3067455 to reflect the stock split.

   Approximately 10% of the shares of Motorola common stock that you would
otherwise be entitled to receive in the merger will be deposited in an escrow
account and may be used to compensate Motorola in the event that it is entitled
to indemnification under the merger agreement. Shares of Motorola common stock
subject to issuance under options granted under C-Port's 1997 stock incentive
plan to be assumed by Motorola in the merger will not be included in the escrow
account.

   In addition, you will receive cash payments instead of any fractional
Motorola shares you would have otherwise received. After giving effect to the
merger, former C-Port stockholders will hold less than 1% of the outstanding
Motorola shares.

   Q: What happens as the market price of Motorola stock fluctuates?

   A: The exchange ratio is a fixed number and will not be adjusted in the
event of any increase or decrease in the price of Motorola common stock. The
value of the shares of Motorola common stock you will receive in the merger
will therefore fluctuate as the price of Motorola common stock increases or
decreases. You should therefore obtain a current market quotation for Motorola
common stock before voting on the merger.

   Q: What impact will the Motorola stock split have on what I will receive in
the merger?

   A: On February 29, 2000, the Motorola board of directors approved a three-
for-one stock split of Motorola's common stock payable on June 1, 2000 in the
form of a stock dividend to Motorola stockholders of record on May 15, 2000.
Under the merger agreement, if the merger occurs after May 15, 2000, the
exchange ratio will automatically adjust to give effect to the Motorola stock
split.

   Q: What is the escrow fund and how does it work?

   A: If the merger is completed, Motorola will deposit 290,786 shares of
Motorola common stock into an escrow account. In the event that the merger
occurs after May 15, 2000, the number of shares to be deposited

                                       1
<PAGE>

into the escrow account will be increased to 872,358, in order to give effect
to the three-for-one split of Motorola's common stock payable in the form of a
stock dividend on June 1, 2000 to all Motorola stockholders of record on May
15, 2000.

   Shares of Motorola common stock subject to issuance under options under C-
Port's 1997 stock incentive plan to be assumed by Motorola in the merger will
not be included in the escrow account.

   The escrowed shares will be available to compensate Motorola in the event
that it is entitled to indemnification from the C-Port stockholders under the
merger agreement. To the extent that some or all the escrowed shares are not
required to indemnify Motorola, those escrowed shares will be distributed to
the C-Port stockholders entitled to receive those shares within five business
days following the first anniversary of the consummation of the merger.

   Q: Who must approve the merger?

   A: In addition to the approvals by the Motorola board of directors and the
C-Port board of directors, each of which has already been obtained, and
governmental and other regulatory approvals, the merger agreement and the
merger must be approved by C-Port's stockholders.

   Q: What stockholder vote is required to approve the merger agreement and the
merger?

   A: A majority of the outstanding shares of C-Port common stock entitled to
vote constitutes a quorum for the C-Port special meeting. The affirmative vote
of the holders of at least a majority of the outstanding shares of C-Port
common and preferred stock voting as a single class and 55% of the outstanding
shares of C-Port preferred stock is required to approve the merger agreement
and the merger. Certain stockholders of C-Port holding in the aggregate enough
shares to approve the merger agreement and the merger have entered into a
voting agreement under which they have agreed to vote all of their shares of C-
Port stock in favor of the merger agreement and the merger. Consequently,
approval of the merger agreement and the merger is assured.

   Q: Does the C-Port board of directors recommend approval of the merger
agreement and the merger?

   A: Yes. After careful consideration, the C-Port board of directors
unanimously recommends that its stockholders vote in favor of the merger
agreement and the merger. For a more complete description of the recommendation
of the C-Port board of directors, see the section entitled "The Merger--C-
Port's Reasons for the Merger" on page 22 and "The Merger--Recommendation of
the C-Port Board of Directors" on page 24.

   Q: What if the merger is not completed?

   A: It is possible the merger will not be completed. That might happen if,
for example, a required condition to the closing of the merger set forth in the
merger agreement is not satisfied. Should that occur, none of Motorola, C-Port
or any third party is under any obligation to make or consider any alternative
proposals regarding the purchase of your shares of C-Port stock.

   Q: What do I need to do now?

   A: We urge you to read this proxy statement/prospectus, including the
appendices, carefully, and to consider how the merger will affect you as a
stockholder of C-Port. You also may want to review the documents referenced
under "Where You Can Find More Information" on page 67.

   Q: How do I vote?

   A: You may vote by mailing a signed proxy card in the enclosed return
envelope as soon as possible so that those shares may be represented at the
special meeting. You may also attend the special meeting and vote in person.

                                       2
<PAGE>

   Q: Can I change my vote?

   A: Yes. You may change your vote by delivering a later-dated, signed proxy
card to C-Port's secretary before the special meeting of C-Port stockholders,
or by attending the special meeting and voting in person.

   Q: Is the merger taxable?

   A: It is a condition of the merger that each of Motorola and C-Port receives
an opinion from its respective tax counsel stating that the merger will qualify
as a reorganization for U.S. federal income tax purposes. As a result of the
merger qualifying as a reorganization for U.S. federal income tax purposes, C-
Port stockholders will generally not recognize any gain or loss for U.S.
federal income tax purposes on the exchange of their C-Port shares solely for
Motorola shares in the merger, except for cash received in lieu of fractional
shares of Motorola stock.

   We describe the material U.S. federal income tax consequences of the merger
in more detail on pages 32-33. The tax consequences to you will depend on the
facts of your own situation. Please consult your tax advisor for a full
understanding of the tax consequences to you of the merger.

   Q: Am I entitled to appraisal rights?

   A: Yes. You will be entitled to appraisal rights in connection with the
merger provided that you give written demand for appraisal and comply with all
relevant provisions of Section 262 of the Delaware General Corporation Law
explained on pages 34-36 and in Appendix D to this proxy statement/prospectus.

   Q: When do you expect to complete the merger?

   A: We expect to complete the merger during the second quarter of this year.
Because the merger is subject to governmental approvals, however, we cannot
predict the exact timing. We are awaiting the expiration of the waiting period
under the Hart-Scott-Rodino Act.

   Q: Should I send in my C-Port stock certificates now?

   A: No. After we complete the merger, Motorola's exchange agent will send
instructions to you regarding your C-Port shares that were converted in the
merger. These instructions will explain how to exchange your C-Port share
certificates for Motorola share certificates and, if applicable, cash instead
of any fractional shares of Motorola stock that you would otherwise receive in
the merger. Please do not send in your C-Port stock certificates with your
proxy card.

   Q: When and where is the special meeting?

   A: The special meeting will be held at [     ].m., local time, on
[         ], 2000 at the offices of Hale and Dorr LLP, 60 State Street, Boston,
Massachusetts 02109.

   Q: What else will happen at the meeting?

   A: We know of no other matters which are expected to come before the special
meeting.

   Q: Whom can I call with questions?

   A: If you have any questions about the merger or any related transactions,
please call C-Port at (978) 773-2395 (and ask for John Gavin, C-Port's Chief
Financial Officer) or Motorola's Investor Relations Department at (800) 262-
8509.

   If you would like copies of any of the documents we refer to in this proxy
statement/prospectus, you should call Motorola at (800) 262-8509.

   C-Port is a corporation organized under the laws of the State of Delaware.

Risk Factors (see page 14)

   See "Risk Factors" for a discussion of certain risks that should be
considered by C-Port stockholders in evaluating whether to approve the merger
and the merger agreement and thereby become holders of Motorola common stock.

The C-Port Special Meeting (see page 18)

   The special meeting of the C-Port stockholders will be held on
[            ], [            ], 2000, at [         ].m., local time, at the
offices of Hale and Dorr LLP, 60 State Street, Boston, Massachusetts 02109. At
the special meeting, C-Port stockholders will be asked:

  . to approve the merger agreement and the merger and, in so doing, to
    appoint Laurence G. Walker as stockholder representative under the merger
    agreement; and

  . to act on other matters that may be properly submitted to a vote at the
    C-Port special meeting.

Record Date; Stockholders Entitled to Vote (see page 18)

   You can vote at the special meeting if you owned C-Port shares at the close
of business on [          ], 2000, the record date.

   On the record date, there were [        ] shares of C-Port common stock,
[        ] shares of C-Port Series A preferred stock, [        ] shares of C-
Port Series B preferred stock and [         ] shares of C-Port Series C
preferred stock outstanding and entitled to vote at the special meeting. C-
Port stockholders will have one vote at the special meeting for each share of
C-Port common stock that they owned on the record date, and will have the
number of votes equal to the number of shares of C-Port common stock into
which each share of C-Port preferred stock that they owned on the record date
was convertible, whether when voting together with the common stock as a
single class or as a separate vote of the preferred stock voting together as a
single class.

   As of March 23, 2000, each share of C-Port Series A, Series B and Series C
preferred stock was convertible into one whole share of C-Port common stock.
On March 14, 2000, holders of at least 55% of the issued and outstanding
shares of C-Port preferred stock approved and adopted, by written consent in
lieu of a meeting, a resolution electing not to treat the merger as a
"liquidation, dissolution or winding up" of C-Port under the provisions of C-
Port's charter and a resolution to convert each issued and outstanding share
of C-Port preferred stock into C-Port common stock, immediately prior to the
effective time of the merger. Therefore, at the effective time of the merger,
C-Port will have no shares of preferred stock issued and outstanding.

Vote Required (see page 19)

   The affirmative vote of each of the following is required to approve the
merger agreement and the merger:

  . a majority of the outstanding shares of C-Port common stock and C-Port
    preferred stock on the record date, voting together as a single class;
    and

  . at least fifty-five percent (55%) of the outstanding shares of C-Port
    Series A, Series B and Series C preferred stock, voting as a single class
    on an as converted into common stock basis.

Voting Agreement (see page 47)

   Certain officers, directors and stockholders of C-Port have entered into a
voting agreement with Motorola, pursuant to which they have agreed, among
other things, to vote the C-Port stock they own "FOR" approval of the merger
agreement and the merger. Each of these stockholders has also granted an
irrevocable proxy and a power of attorney to Motorola representatives to vote
his, her or its shares of C-Port stock "FOR" approval of the merger agreement
and the merger.

   On the record date, these C-Port stockholders collectively owned and were
entitled to vote approximately:

  . 55.7% of the outstanding shares of C-Port common stock and preferred
    stock, voting together as a single class; and

  . 69.8% of the C-Port preferred stock, voting together as a single class.

Recommendation of the C-Port Board of Directors (see page 24)

   The C-Port board of directors has unanimously approved the merger
agreement, the merger and the transactions contemplated in the merger
agreement and recommends that C-Port stockholders vote "FOR" approval of the
merger agreement and the merger.

Opinion of Financial Advisor to C-Port (see page 24)

   Deutsche Bank Securities Inc., C-Port's financial advisor, has rendered a
written opinion dated February 17, 2000 to the C-Port board of directors that,
as of the date of the opinion, the exchange ratio was fair, from a financial
point of view, to C-Port's stockholders. The full text of the written opinion
of Deutsche Bank is attached as Appendix B to this proxy statement/prospectus.
We encourage you to read the opinion carefully in its entirety to understand
the procedures followed, assumptions made, matters considered and limitations
on the review undertaken by Deutsche Bank in providing its opinion. The
opinion of Deutsche Bank is directed to the C-Port board of directors and does
not constitute a recommendation to any C-Port stockholder with respect to any
matter relating to the merger.

Accounting Treatment (see page 29)

   Motorola will account for the merger as a purchase of a business, which
means that the assets and liabilities of C-Port, including intangible assets,
will be recorded at their fair value with the remaining purchase price
reflected as goodwill and the results of operations and cash flows of C-Port
will be included in Motorola's results prospectively after the merger.

Interests of C-Port Officers and Directors in the Merger (see page 31)

   When considering the merger agreement and the merger, C-Port's board of
directors was aware that certain of the officers and directors of C-Port may
have interests and arrangements that are different from your interests as
stockholders. These include rights under certain stock-based employee benefits
awards, as well as arrangements with Motorola regarding employment following
the merger. In addition, C-Port officers and directors have customary rights
to indemnification against certain liabilities.

Material Federal Income Tax Consequences of the C-Port Merger (see page 32)

   The merger is intended to qualify as a reorganization within the meaning of
the Internal Revenue Code. It is a condition of the merger that each of
Motorola and C-Port receive an opinion from its tax counsel stating that the
merger will qualify as a reorganization for U.S. federal income tax purposes.
As a result of the merger qualifying as a reorganization for U.S. federal
income tax purposes, C-Port stockholders generally will not recognize any gain
or loss for U.S. federal income tax purposes on the exchange of their C-Port
shares solely for Motorola shares in the merger, except for cash received in
lieu of fractional shares of Motorola stock.

Regulatory Matters (see page 33)

   Motorola and C-Port must make certain filings and take other actions
necessary to obtain approvals from U.S. governmental authorities in connection
with the merger, including antitrust authorities. Motorola and C-Port have
agreed to use reasonable best efforts to obtain any required governmental
consents and approvals, but Motorola is not required to agree to any
conditions, divestitures or expenditures of money to a third party in exchange
for any consent that, in any such case, would be materially adverse to
Motorola, its subsidiaries and C-Port, taken as a whole.

   The waiting period during which the U.S. antitrust authorities review the
merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as
amended, will expire on April 16, 2000. We expect to obtain all other material
required governmental approvals and, if all other conditions to the merger are
satisfied, complete the merger in the second quarter of 2000. We cannot be
certain, however, that Motorola and C-Port will obtain all required
governmental approvals, or that we will obtain these approvals without
conditions that would be detrimental to Motorola or C-Port.

Statutory Appraisal Rights (see page 34)

   Appraisal rights are provided for under Delaware law. C-Port stockholders
who do not vote for the merger and who satisfy certain other conditions
described on pages 35-37 and in Appendix D to this proxy statement/prospectus
are entitled to be paid the "fair value" of their shares of C-Port common or
preferred stock, as determined by the Delaware chancery court. Since appraisal
rights are only available to C-Port stockholders who satisfy certain
conditions, you should carefully review the section of this proxy
statement/prospectus titled "The Merger--Appraisal Rights Procedures" beginning
on page 34 and the copy of the Delaware appraisal rights statute attached as
Appendix D to this proxy statement/prospectus.

Management and Operations of C-Port after the Merger (see page 37)

   After the merger, Motorola plans to operate C-Port as a part of Motorola's
Network and Computing Systems Group within the Semiconductor Products Sector of
Motorola. Motorola expects that Laurence G. Walker, President and Chief
Executive Officer of C-Port, will continue to lead the business and that the
other members of current C-Port management and C-Port employees will continue
to work at C-Port after the merger. The headquarters of C-Port is expected to
remain in North Andover, Massachusetts.

What You Will Receive in the Merger (see page 38)

   Under the merger agreement, each of your C-Port common shares will be
exchanged for 0.1022485 of a share of Motorola common stock. As previously
announced by Motorola, on February 29, 2000, Motorola's board of directors
declared a three-for-one stock split of its common stock payable on June 1,
2000 in the form of a stock dividend to its common stockholders of record as of
the close of business on May 15, 2000. If the effective time of the merger
occurs after May 15, 2000, the 0.1022485 exchange ratio will automatically
adjust under the merger agreement to 0.3067455 to reflect the stock split.

                                       7
<PAGE>


   Because the number of Motorola shares that you will receive in the merger is
fixed, the value of the Motorola shares you will receive in the merger will
fluctuate as the market price of Motorola common stock changes. You should
therefore obtain a market quotation of the price of Motorola common stock
before voting on the merger.

   You will have to surrender your C-Port common stock certificates to receive
Motorola common stock certificates. However, please do not send any C-Port
common stock certificates until you receive written instructions from
Motorola's exchange agent after the merger is completed.

Ownership of Shares after the Merger

   After giving effect to the merger, the former C-Port stockholders will hold
less than 1% of the outstanding Motorola common stock as a result of the
merger, based upon the number of issued and outstanding shares of Motorola
stock as of March 23, 2000.

The Merger (see page 38)

   We propose that a wholly owned subsidiary of Motorola formed for the purpose
of the merger merge with and into C-Port. As a result, C-Port will become a
wholly owned subsidiary of Motorola.

   We have attached the merger agreement, which is the legal document that
governs the merger, as Appendix A to this proxy statement/prospectus. We
encourage you to read the merger agreement. We have also filed other related
agreements as exhibits to Motorola's registration statement on Form S-4
containing this proxy statement/prospectus. Please see the section titled
"Where You Can Find More Information" on page 67 for instructions on how to
obtain copies of these exhibits.

Effects of the Merger on the Rights of C-Port Stockholders (see page 38)

   The rights of C-Port stockholders who receive Motorola shares in the merger
will continue to be governed by Delaware law, but will also be governed by
Motorola's charter and Motorola's by-laws. The rights of C-Port stockholders
under Motorola's charter and by-laws will differ in certain respects from the
rights under C-Port's charter and by-laws. See "Comparison of Certain Rights of
Common Stockholders of Motorola and Stockholders of C-Port" on pages 53-58 for
a discussion of the material differences between the rights of holders of
Motorola common stock and of C-Port stock.

Listing of Motorola Common Stock (see page 41)

   It is a condition to the completion of the merger that the Motorola shares
to be issued to the C-Port stockholders in the merger be authorized for listing
on the New York Stock Exchange.

Conditions to the Merger (see page 45)

   We will complete the merger only if certain conditions are satisfied or
waived, including:

  . the requisite approval of the C-Port stockholders;

  . the expiration or termination of all applicable waiting periods, and any
    extensions of these periods, under the Hart-Scott-Rodino Act;

  . the receipt of legal opinions that the merger will be treated as a
    reorganization for U.S. federal income tax purposes;

  . effectiveness of the registration statement on Form S-4 that contains
    this proxy statement/prospectus;

  . the approval of the listing on the New York Stock Exchange of the
    Motorola common stock to be issued to the C-Port stockholders in the
    merger; and

  . the satisfaction of other customary contractual conditions set forth in
    the merger agreement.

                                       8
<PAGE>


Termination (see page 46)

   Either Motorola or C-Port may terminate the merger agreement if:

  . the merger is not completed by May 31, 2000 (subject to extension to June
    30, 2000 under certain circumstances described in the merger agreement);

  . a final and nonappealable governmental order is entered enjoining or
    prohibiting the completion of the merger;

  . the merger agreement fails to receive requisite C-Port stockholder
    approval after a vote; or

  . the other party breaches its representations, warranties or agreements in
    certain circumstances and the breaching party fails to cure the breach
    within 30 days of receiving written notice of the breach.

   Motorola and C-Port may also mutually agree to terminate the merger
agreement without completing the merger.

Fees and Expenses (see page 46)

   Whether or not the merger is completed, Motorola will pay its own fees,
expenses and disbursements incurred by it in connection with the negotiation
and preparation of the merger agreement and Motorola's performance and
compliance thereunder. If the merger is completed, the C-Port stockholders
shall pay, from the escrow fund, the fees, expenses and disbursements of C-Port
and the C-Port stockholders, in excess of $2.5 million in the aggregate for all
such fees, expenses and disbursements, incurred by them in connection with the
negotiation and preparation of the merger agreement and their performance and
compliance thereunder.

   If the merger is not completed, C-Port shall pay all of the fees, expenses
and disbursements incurred by C-Port and the C-Port stockholders in connection
with the negotiation and preparation of the merger agreement and their
performance and compliance thereunder.

Appointment of Stockholder Representative (see page 48)

   As provided by the terms of the merger agreement, the approval by the C-Port
stockholders of the merger agreement and the merger will constitute the
approval of the appointment of Laurence G. Walker as the stockholder
representative under the merger agreement and will be deemed to be the approval
by the C-Port stockholders of the performance by the stockholder representative
of all rights and obligations conferred on the stockholder representative under
the merger agreement and the escrow agreement.

Indemnification; Escrow Agreement (see page 48)

   The merger agreement provides that 290,786 shares of Motorola common stock
will be deposited in escrow with an escrow agent as soon as practicable after
the closing date of the merger. In the event that the merger occurs after May
15, 2000, the number of shares of Motorola common stock to be deposited in the
escrow account will be increased to 872,358 in order to give effect to a three-
for-one split of Motorola's common stock approved by Motorola's board of
directors on February 29, 2000. The number of shares of Motorola common stock
to be received by each C-Port stockholder in the merger will be reduced by
approximately 10% of the shares of Motorola common stock such C-Port
stockholders would otherwise be entitled to receive. Shares of Motorola common
stock subject to issuance under options granted under C-Port's 1997 stock
incentive plan to be assumed by Motorola in the merger will not be included in
the escrow account.

   The escrow account will be the only source available to compensate Motorola
for the indemnification obligations of each C-Port stockholder under the merger
agreement, other than for any claim of fraud. The escrow will terminate one
year after the date of the merger at which time all shares of Motorola stock
that are

                                       9
<PAGE>

in the escrow account and are not the subject of any claim by Motorola will be
released to the C-Port stockholders entitled to receive those shares. Any
shares of Motorola stock that are the subject of a claim will be retained in
the escrow account pending resolution of the claim and thereafter any shares
not used to satisfy Motorola's claims for indemnification will be released to
the C-Port stockholders entitled to receive those shares.

Forward-Looking Statements (see page 66)

   Motorola and C-Port have made forward-looking statements in this proxy
statement/prospectus and in the documents to which we have referred you. These
statements are subject to risks and uncertainties, and therefore may not prove
to be correct. Forward-looking statements include assumptions as to how
Motorola may perform after the merger and, accordingly, it is uncertain whether
any of the events anticipated by the forward-looking statements will transpire
or occur, or, if any of them do transpire or occur, what impact they will have
on the results of operations and financial condition of Motorola or the price
of its stock. See "Special Note Regarding Forward-Looking Statements" on page
66 for further details.

   When we use words like "believes," "expects," "anticipates" or similar
expressions, we are making forward-looking statements. For those statements,
Motorola and C-Port claim the protection of the safe harbor for forward-looking
statements contained in the Private Securities Litigation Reform Act of 1995.

</TABLE>
- --------
(1) Dividend information for fiscal years 1998 and 1999 is provided for shares
    of Motorola common stock outstanding prior to the merger on January 5, 2000
    of General Instrument Corporation with a wholly owned subsidiary of
    Motorola. The dividend information has not been restated to reflect the
    General Instrument merger.

   Motorola common stock is currently traded on the New York Stock Exchange
under the symbol "MOT." Motorola common stock is also listed and traded on the
Chicago, London and Tokyo stock exchanges. As of March 23, 2000, there were
approximately 717,314,579 issued and outstanding shares of Motorola common
stock.

   As previously announced by Motorola, on February 29, 2000, Motorola's board
of directors approved a
three-for-one stock split of its common stock payable on June 1, 2000 in the
form of a stock dividend to its common stockholders of record as of the close
of business on May 15, 2000. If the merger occurs after May 15, 2000, the
record date for the three-for-one stock split, the 0.1022485 exchange ratio
will automatically adjust under the merger agreement to 0.3067455 to reflect
the Motorola stock split.

                                       12
<PAGE>


   Because the exchange ratio in the merger is fixed and because the market
price of Motorola common stock is subject to fluctuation, the market value of
the Motorola shares that you will receive in the merger may increase or
decrease before and after the special meeting of C-Port stockholders. We urge
C-Port stockholders to obtain current market quotations for Motorola common
stock. We cannot give any assurance as to the future prices or markets for
Motorola common stock.

   On February 16, 2000, the last trading day prior to the execution of the
merger agreement, the closing sale price of a Motorola share on the New York
Stock Exchange was $147.88. On March 23, 2000, the most recent practicable date
prior to the printing of this proxy statement/prospectus, the closing price of
a Motorola share on the New York Stock Exchange was $161.50. We urge you to
obtain current market quotations prior to making any decision with respect to
the merger.

   C-Port's capital stock is not listed for trading on any exchange or
automated quotation service. As of the record date, there were approximately
[         ] holders of record of C-Port capital stock. C-Port has never
declared or paid cash dividends on its common stock and does not plan to pay
any cash dividends prior to the merger.

                                  RISK FACTORS

   You should carefully consider the following important factors, in addition
to the other information included and incorporated by reference in this proxy
statement/prospectus, to determine whether to vote for the proposals relating
to the merger. See "Where You Can Find More Information" on page 67.

Risks Relating to the Merger

   C-Port Stockholders May Never Receive 10% Of The Motorola Common Stock. Ten
percent of the shares of Motorola common stock (290,786 shares, subject to
adjustment to give effect to the Motorola three-for-one stock split if the
merger is completed after May 15, 2000) that would otherwise be received by C-
Port stockholders in the merger will be placed in an escrow account to secure
the indemnification obligations of the C-Port stockholders under the merger
agreement. Shares of Motorola common stock subject to issuance under stock
options granted under C-Port's 1997 stock incentive plan to be assumed by
Motorola in the merger will not be included in the escrow account. The escrow
account will terminate one year after the date of the merger. If Motorola makes
no claims for indemnification, all of the shares held in escrow will be
released to the C-Port stockholders. However, Motorola may make claims against
the shares held in escrow for damages and liabilities (including reasonable
legal fees) arising out of:

  . any inaccuracy in any representation or warranty made by C-Port in the
    merger agreement or in the disclosure schedule to the merger agreement;

  . any breach or default by C-Port of any of the covenants or agreements
    given or made by it in the merger agreement;

  . certain fees, expenses and disbursements incurred by C-Port in connection
    with the merger in excess of $2.5 million;

  . any governmental action, order or directive, administrative proceeding or
    ruling;

  . personal or bodily injuries or damage to any premises;

  . any violation or alleged violation of environmental laws existing prior
    to the effective time of the merger; and

  . certain other matters described in the disclosure schedule to the merger
    agreement.

   There can be no assurance that the C-Port stockholders will receive any of
the shares held in the escrow account should they be required to indemnify
Motorola under the terms of the merger agreement. See "The Merger Agreement--
Indemnification of Motorola; Escrow Agreement" on page 48 and "The Merger--
Merger Consideration" on page 29.

   No Adjustment To The Merger Terms Will Be Made As A Result Of Changes In The
Market Price Of Motorola's Common Stock. Under the merger agreement, each share
of C-Port stock will be converted into the right to receive 0.1022485 of a
share of Motorola common stock. This exchange ratio will be adjusted as
necessary to give effect to any reclassification, stock split, stock dividend,
reorganization or other similar exchange with respect to Motorola or C-Port
common stock occurring before the merger. The exchange ratio is a fixed number
and will not be adjusted in the event of any increase or decrease in the price
of Motorola common stock. The price of Motorola common stock at the closing of
the merger may vary from its price on the date of this proxy
statement/prospectus and on the date of the special meeting of C-Port
stockholders. The price of Motorola common stock may vary because of changes in
the business, operations or prospects of Motorola, the timing of the completion
of the merger, the prospects of post-merger operations, general market and
economic conditions and other factors. Because the date that the merger is
completed may be later than the date of the special meeting, the price of
Motorola common stock on the date of the special meeting may not be indicative
of its price on the date the merger is completed. We urge C-Port stockholders
to obtain current market quotations for Motorola common stock.

                                       14
<PAGE>

   Conditions To The Merger May Not Be Satisfied. The merger agreement contains
conditions that, if not satisfied, would result in the merger not occurring,
even though the C-Port stockholders approved it. We cannot assure you that all
of the closing conditions to the merger will be satisfied, that any unsatisfied
conditions will be waived or that the merger will occur. If the merger does not
occur, C-Port may incur significant expenses that could have a material adverse
affect on the financial and operating results of C-Port.

   If The Merger Is Not Completed, C-Port May Be Unable To Attract Another
Strategic Partner On Equivalent Or More Attractive Terms Than Those Being
Offered By Motorola. If the merger agreement is terminated and C-Port's board
of directors determines that it is in the best interests of the C-Port
stockholders to seek a merger or business combination with another strategic
partner, C-Port cannot assure you that it will be able to find a partner
offering terms equivalent or more attractive than the price and terms offered
by Motorola in the merger.

   C-Port May Lose An Opportunity To Enter Into A Merger Or Business
Combination With Another Party On More Favorable Terms Because Of Provisions In
The Merger Agreement Which Prohibit C-Port From Entering Into Such Transactions
Or Soliciting Such Proposals. While the merger agreement is in effect, C-Port
is prohibited from entering into or soliciting, initiating or encouraging any
inquiries or proposals that may lead to a proposal or offer for a merger, with
any person other than Motorola. As a result of this prohibition, C-Port may
lose an opportunity to enter into a transaction with another potential partner
on more favorable terms.

   The Price Of Motorola Common Stock May Be Affected By Factors Different From
Those Affecting The Value Of C-Port Stock. Upon completion of the merger, C-
Port stockholders will become Motorola common stockholders. Motorola's business
differs from that of C-Port, and Motorola's results of operations, as well as
the price of Motorola common stock, may be affected by factors different from
those affecting C-Port's results of operations and the value of C-Port stock.
For a discussion of Motorola's business and certain factors to consider in
connection with its business, see Motorola's Annual Report on Form 10-K for the
fiscal year ended December 31, 1999, which is incorporated by reference in this
proxy statement/prospectus.

   Some Of C-Port's Directors And Officers Have Interests That Differ In
Several Respects From C-Port Stockholders. In considering the recommendation of
the C-Port board of directors to approve the merger agreement and the merger,
you should consider that some of C-Port's directors and officers have interests
that differ from, or are in addition to, their interests as C-Port stockholders
generally. These interests include the receipt of Motorola stock options,
benefits provided to them by Motorola under employment agreements and the
continuation of certain indemnification arrangements.

   Clients Of Motorola And/Or C-Port May Delay Or Cancel Contracts As A Result
Of Concerns Over The Merger. The announcement and closing of the merger could
cause clients and potential clients of Motorola and C-Port to delay or cancel
contracts as a result of client concerns and uncertainty over the combined
company's offerings, personnel or services. Such a delay or cancellation could
have a material adverse effect on the business, operating results and financial
condition of Motorola and C-Port.

Risks Related to C-Port

   C-Port Has A History Of Losses And Expects To Incur Future Losses. Since its
inception in November 1997, C-Port has not achieved profitability. Although its
revenue has grown in fiscal years 1999 and 2000, C-Port cannot assure you that
its revenue will continue to grow or that it will realize sufficient revenue to
achieve profitability. C-Port has incurred cumulative net losses of
approximately $22.7 million from inception through December 31, 1999, including
losses of approximately $5.5 million for fiscal year 1998 and $17.0 million for
fiscal year 1999. As of December 31, 1999, C-Port had an accumulated deficit of
approximately

                                       15
<PAGE>

$24.0 million. If the merger with Motorola is not consummated, C-Port would
expect to increase its operating expenses to expand its sales and marketing
activities, develop new distribution channels, fund increased levels of
research and development and build its operational infrastructure. If C-Port's
future revenue does not increase substantially, these increased expenditures
would have a materially adverse effect on C-Port's future business, results of
operations and financial condition.

   C-Port Will Need Additional Financing. If the merger with Motorola is not
consummated and C-Port continues as a stand-alone company, C-Port will not have
sufficient cash resources to continue its business operations as they are now
being conducted without obtaining significant additional debt and/or equity
funds to provide working capital for C-Port's continuing operations. While C-
Port believes that it would be able to raise the funds required to finance its
operations as a stand-alone company, it cannot assure you that the required
funds would be available when needed or that they can be obtained on terms
favorable to C-Port. If the required funds cannot be obtained, C-Port could be
forced to revise its business plans, including possible curtailment of its
future business operations, reduction of its planned future growth or a
combination with another company on terms less favorable than the terms
governing the merger with Motorola and C-Port.

                           THE C-PORT SPECIAL MEETING

   We are furnishing this proxy statement/prospectus to C-Port stockholders in
connection with the solicitation of proxies from C-Port stockholders for use at
the special meeting of C-Port stockholders to be held on [         ], 2000 and
at any adjournment or postponement of the meeting. We are also furnishing this
proxy statement/prospectus to C-Port stockholders as a prospectus in connection
with the issuance by Motorola of shares of Motorola stock in the merger.

Date, Time and Place

   The special meeting will be held on [         ], [         ], 2000, at [
 ].m. local time, at the offices of Hale and Dorr LLP, 60 State Street, Boston,
Massachusetts 02109.

Matters to be Considered at the Special Meeting

   At the special meeting of C-Port stockholders, and any adjournment of the
special meeting, C-Port stockholders will be asked:

  . to consider and vote upon a proposal to approve and adopt the Agreement
    and Plan of Merger by and among Motorola, CP Acquisition Corp. and C-
    Port, dated as of February 17, 2000, and the merger under which C-Port
    will become a wholly owned subsidiary of Motorola, and the appointment of
    Laurence G. Walker as stockholder representative under the merger
    agreement; and

  . to consider and transact such other matters which may properly come
    before the special meeting or any and all adjournments thereof.

Board of Directors Recommendation

   The C-Port board of directors has unanimously approved the merger agreement
and the merger and recommends a vote "FOR" approval of the merger agreement and
the merger.

Record Date

   The C-Port board of directors fixed the close of business on [          ],
2000 as the record date for the special meeting. Accordingly, only stockholders
of record of C-Port stock at the close of business on [          ], 2000 are
entitled to notice of and to vote at the special meeting.

Quorum

   The presence at the special meeting, either in person or by proxy, of a
majority of the C-Port shares issued and outstanding on the record date is
necessary to constitute a quorum to transact business at that meeting. If a
quorum is not present, it is expected that the special meeting will be
adjourned or postponed in order to solicit additional proxies. Abstentions will
be counted for the purpose of determining whether a quorum is present.

Stockholders Entitled to Vote

   At the close of business on the record date, [          ], 2000, there were
[         ] shares of C-Port common stock outstanding and entitled to vote held
by [      ] stockholders of record. At the close of business on the record
date, there were [         ] shares of C-Port preferred stock outstanding and
entitled to vote held by [         ] stockholders of record.

   The holders of C-Port common stock are entitled to cast one vote for each
share of common stock they hold on each matter submitted to the common
stockholders for a vote at the special meeting. The holders of C-Port Series A
preferred stock, Series B preferred stock and Series C preferred stock are
entitled to cast one vote for each share of common stock into which their
preferred stock could then be converted on each matter as to which the
preferred stockholders are entitled to vote at the special meeting.

                                       18
<PAGE>

Vote Required

   Approval and adoption of the merger agreement and the merger requires the
affirmative vote of the holders of a majority of the C-Port common and
preferred shares outstanding on the record date voting as a single class and
the affirmative vote of the holders of at least 55% of the outstanding shares
of preferred stock voting as a single class.

   Failure to vote and abstentions will not be deemed to be cast either "FOR"
or "AGAINST" the merger agreement and the merger. However, because approval and
adoption of the merger agreement and the merger requires the affirmative vote
of the holders of a majority of the outstanding C-Port shares, the failure to
vote and abstentions will have the same effect as a vote "AGAINST" the merger
agreement and the merger.

Voting Agreement

   On February 17, 2000, certain stockholders of C-Port, including certain
officers and directors of C-Port, entered into a voting agreement, pursuant to
which, among other things, they agreed to vote their shares of C-Port stock
"FOR" approval of the merger agreement and the merger. A copy of the voting
agreement is attached as Appendix C to this proxy statement/prospectus. Each of
these stockholders has also granted an irrevocable proxy and a power of
attorney to Motorola representatives to vote his, her or its shares of C-Port
stock "FOR" approval of the merger agreement and the merger. On the record
date, the C-Port stockholders that are parties to the voting agreement
collectively owned and were entitled to vote approximately:

  . 55.7% of the outstanding shares of C-Port common stock and preferred
    stock, voting together as a single class; and

  . 69.8% of the C-Port preferred stock, voting together as a single class.

Proxies

   All shares represented by properly executed proxy cards received in time for
the special meeting will be voted at the special meeting in the manner
specified by the holders. Properly executed proxy cards that do not contain
voting instructions with respect to approval of the merger agreement and the
merger will be voted "FOR" approval of the merger agreement and the merger.

   Shares of C-Port stock represented at the special meeting but not voting,
including shares of C-Port stock for which proxy cards have been received but
for which holders of shares have abstained, will be treated as present at the
special meeting for purposes of determining the presence or absence of a quorum
for the transaction of all business.

   Only shares affirmatively voted for approval of the merger agreement,
including properly executed proxy cards that do not contain voting
instructions, will be counted as favorable votes for the merger proposal.

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

Revocability of Proxies

   You may revoke your proxy at any time prior to its use:

  . by delivering to the secretary of C-Port at the address set forth below a
    signed notice of revocation or a later-dated, signed proxy card; or

  . by attending the special meeting and voting in person.

                                       19
<PAGE>

   Attendance at the special meeting is not in itself sufficient to revoke a
proxy.

   All written notices of revocation and other communications with respect to
revocation of proxies should be addressed to C-Port Corporation, One High
Street, North Andover, Massachusetts 01845, Attention: Secretary. A proxy
appointment will not be revoked by death or incapacity of the C-Port
stockholder executing the proxy card unless, before the shares are voted,
notice of such death or incapacity is filed with C-Port's secretary or other
person responsible for tabulating votes on C-Port's behalf.

Solicitation of Proxies and Expenses

   C-Port will pay the cost of soliciting proxies from its stockholders. In
addition to solicitation by mail, C-Port's directors, officers and employees
may solicit proxies by telephone, fax, e-mail, telegram or in person.

   Please do not send stock certificates with your proxy card. A transmittal
form with instructions concerning the surrender of C-Port stock certificates
will be mailed to you by Motorola's exchange agent promptly after completion of
the merger.

Dissenters' Rights to Appraisal

   If you do not wish to accept Motorola common stock in the merger, you have
the right under Delaware law to have the fair value of your C-Port shares
determined by the Delaware chancery court. This right to appraisal is subject
to a number of restrictions and technical requirements. Generally, in order to
exercise your appraisal rights:

  . you must send a written demand to C-Port for appraisal in compliance with
    Delaware law before the vote on the merger;

  . you must not vote in favor of the merger; and

  . you must continuously hold your C-Port stock, from the date you make the
    demand for appraisal through the closing of the merger.

Merely voting against the merger will not protect your rights to an appraisal.
Appendix D to this proxy statement/prospectus contains a copy of the Delaware
statute governing appraisal rights. Failure to follow all the steps required by
Delaware law will result in the loss of your rights to appraisal. The Delaware
law requirements for exercising appraisal rights are described in further
detail on pages 34-36. See "The Merger--Statutory Appraisal Rights" on page 34
and "The Merger--Appraisal Rights Procedures" on pages 34-36.

                                   THE MERGER

   This section of the proxy statement/prospectus, as well as the next section
titled "The Merger Agreement" beginning on page 38, describes certain aspects
of the proposed merger. These sections highlight key information about the
merger agreement and the merger, but they may not include all the information
that a stockholder would like to or should know. The merger agreement is
attached as Appendix A to this proxy statement/prospectus. We urge stockholders
to read the merger agreement in its entirety.

Structure of the Merger

   If the merger is adopted by the holders of a majority of the outstanding C-
Port common and preferred shares voting as a single class and by 55% of the
outstanding C-Port preferred shares voting as a single class and the other
conditions to the merger are satisfied, CP Acquisition Corp., a wholly owned
subsidiary of Motorola formed for the purpose of the merger, will merge with
and into C-Port, with C-Port being the surviving corporation in the merger and
becoming a wholly owned subsidiary of Motorola.

Background

   In August 1998, representatives of Motorola and C-Port met in Austin, Texas
to discuss a possible strategic relationship. These discussions did not lead to
an acquisition proposal.

   In September 1999, representatives of Motorola and C-Port resumed
discussions concerning a possible relationship between the two companies and,
in October 1999, they entered into a non-disclosure agreement to facilitate
further discussions.

   Following a visit to C-Port's headquarters in North Andover, Massachusetts
in October 1999, Motorola informed Laurence G. Walker, C-Port's President and
Chief Executive Officer, that Motorola was interested in exploring a possible
acquisition of C-Port.

   In early December 1999, Daniel Artusi, Corporate Vice President and General
Manager of Motorola's Networking and Computing Systems Group, and Dr. Walker
met in Austin, Texas along with other representatives of Motorola and C-Port to
explore in further detail the possible acquisition of C-Port by Motorola. At
the end of the meeting, the parties agreed to continue their discussions, which
continued periodically thereafter.

   The C-Port board of directors, which had previously been advised concerning
Dr. Walker's discussions with Motorola, was further briefed at its December 17,
1999 meeting. During the week of December 20, 1999, senior executives of
Motorola were briefed concerning discussions to date with C-Port. On December
23, 1999, Motorola sent a letter of intent to Dr. Walker describing an
acquisition proposal. This letter was followed by meetings between
representatives of both companies.

   On January 4, 2000, C-Port retained Deutsche Bank to serve as its financial
advisor with respect to the merger.

   During January, Motorola and C-Port, together with their advisors,
negotiated the principal terms of the merger and on January 25, 2000, the
parties entered into an exclusivity agreement to facilitate finalization of the
terms of the transaction.

   In early February 2000, representatives of Motorola, C-Port and their
advisors met in Chicago, Illinois to negotiate the final terms of the merger
agreement and various other legal, financial and regulatory matters.

   On February 6, 2000 and February 9, 2000, the C-Port board of directors met
with representatives of Hale and Dorr, C-Port's legal advisor, and Deutsche
Bank in attendance, in order to discuss the terms and conditions of the merger
and the status of the negotiations.

   On February 14, 2000, the Motorola board of directors approved the merger
agreement and the merger at a telephonic meeting.

                                       21
<PAGE>

   On February 16, 2000, the C-Port board of directors met twice with
representatives of Hale and Dorr and Deutsche Bank in attendance to discuss in
detail the terms and conditions of the merger.

   On February 17, 2000, the C-Port board of directors met with representatives
of Hale and Dorr and Deutsche Bank in attendance. At that meeting, the C-Port
board of directors reviewed discussion materials prepared by Deutsche Bank with
regard to Motorola's offer and engaged in a detailed discussion of the merits
of the proposed transaction to C-Port's stockholders. Deutsche Bank delivered
its oral opinion to the C-Port board of directors to the effect that, as of
that date, based upon and subject to the assumptions made, matters considered
and limits of the review undertaken by Deutsche Bank, the exchange ratio
between C-Port and Motorola was fair, from a financial point of view, to C-Port
stockholders. Based on their discussions and the materials presented at the
meeting, C-Port's board of directors concluded that Motorola's proposal was in
the best interests of C-Port and its stockholders and authorized the merger
agreement, the voting agreement and the other related documents and the merger.

   As of February 17, 2000, the merger agreement was executed by Motorola, CP
Acquisition Corp. and C-Port. In connection with the execution of the merger
agreement, certain stockholders of C-Port entered into a voting agreement
pursuant to which they agreed, among other things, to vote their shares of C-
Port stock in favor of the merger.

   On February 22, 2000, before the opening of trading on the New York Stock
Exchange, Motorola and C-Port issued a joint press release announcing the
proposed merger.

Motorola's Reasons for the Merger

   As part of its growth strategy, Motorola's Semiconductor Products Sector
seeks opportunities to develop smarter networks faster and strengthen its
product portfolio in the networking equipment industry. By combining Motorola's
Digital DNA(TM) technologies with C-Port's product and development offerings,
which enable high bandwidth network processing applications, Motorola seeks to
offer its customers a scalable family of solutions from the SOHO, to the edge,
to the core of the network. Through the acquisition of C-Port, Motorola
believes it can deliver a complete communications platform including host,
integrated communications and network processors, digital signal processors,
development environments and application software.

   In particular, the transaction allows Motorola to benefit from C-Port's
pioneering advances in programmable network processor development. C-Port's C-
5(TM) DCP product is one of the industry's first totally programmable network
processors. When utilized with Motorola's other communications processors, C-
Port's processors allow network equipment manufacturers to build re-
programmable smart networking equipment. This gives service providers the
ability to create and offer new services quickly and efficiently to handle the
proliferation of e-commerce, multimedia content, and other Internet services.

C-Port's Reasons for the Merger

   The C-Port board of directors has unanimously approved the merger agreement
and the transactions contemplated thereby and believes that the terms of the
merger agreement and the merger are fair to, and in the best interests of, C-
Port and its stockholders. The C-Port board of directors recommends that the C-
Port stockholders adopt the merger agreement and the merger. The C-Port board
of directors considered and reviewed with management the positive factors
listed below, among other factors, in reaching its decision to approve the
merger agreement and the merger:

  . to enable C-Port to capitalize on Motorola's extensive international and
    domestic sales, marketing, and distribution expertise and resources,
    thereby increasing the visibility and accessibility of C-Port's products;

  . to utilize Motorola's research and development resources to enable C-Port
    to accelerate its development activities;

                                       22
<PAGE>

  . the strategic fit of combining C-Port's Communications Processor
    expertise with that of Motorola's as well as Motorola's extensive product
    lines in host processors, memories, and other semiconductor products
    allowing C-Port's OEM customers an easier design capability for their
    products and to quickly deliver them to market;

  . to access additional financial resources to accelerate C-Port's growth
    and access to the public markets to raise further capital;

  . the fact that the merger was structured as a reorganization for federal
    income tax purposes;

  . the benefit to the stockholders of C-Port without enduring the time,
    expense and uncertainty involved in an initial public offering; and

  . the liquidity that the transaction would provide in light of the
    consideration being shares of Motorola common stock, which are publicly
    traded securities on the New York Stock Exchange and are more readily
    marketable than shares of C-Port stock.

   In the course of its deliberations, the C-Port board of directors reviewed
with C-Port management and C-Port's legal and financial advisers a number of
additional factors that the C-Port board of directors deemed relevant to the
merger, including, but not limited to:

  . the strategic importance to C-Port of the proposed merger;

  . the consideration to be received by C-Port stockholders in the merger;

  . information concerning C-Port's and Motorola's respective businesses,
    prospects, strategic business plans, financial performance and condition,
    results of operations, technology positions, management and competitive
    positions;

  . C-Port management's view as to the financial condition, results of
    operations, and business of C-Port before and after giving effect to the
    merger;

  . C-Port management's view as to the prospects of C-Port's continuing as an
    independent company;

  . C-Port management's view as to C-Port's ability to gain access to the
    necessary capital to meet its strategic business goals in both the near
    term and the long term as well as the relative costs associated with
    obtaining the capital;

  . current financial conditions and historical market prices, volatility and
    trading information with respect to Motorola common stock;

  . C-Port management's view as to the effect of the merger on the core
    business of C-Port, including its research and development efforts,
    potential synergy of Motorola's technologies with C-Port's technologies,
    the breadth of Motorola's product offerings, and sales and marketing
    infrastructure;

  . the impact of the merger on C-Port's strategic marketing partners,
    employees, and customers; and

  . the compatibility of the managements of C-Port and Motorola.

   During the course of its deliberations concerning the merger, the C-Port
board of directors also identified and considered a variety of potentially
negative factors that could materialize as a result of the merger, including,
but not limited to:

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

  . the transaction costs involved in connection with closing the merger;

  . the possibility that the merger might not be consummated and the effect
    of the public announcement of the merger on C-Port's partners, customers
    and employees;

  . the risks associated with obtaining the necessary approvals required to
    complete the merger;

  . the effects of the diversion of management resources necessary to respond
    to due diligence inquiries and the negotiation and consummation of the
    merger; and

  . the other risks described under "Risk Factors."

                                       23
<PAGE>

   The foregoing factors are not intended to be an exhaustive list of all
factors considered. In view of the variety of factors considered, the C-Port
board found it impractical to and did not, quantify or otherwise assign
relative weights to the specific factors discussed above.

Recommendation of the C-Port Board of Directors

   After extensive discussion among the members of the board of directors, the
C-Port board of directors concluded that the risks associated with the merger
were outweighed by the potential benefits of the merger and unanimously
determined that the merger is fair to, and in the best interests of, C-Port and
its stockholders. Some directors of C-Port may be deemed to have a conflict of
interest in the C-Port board of directors' approval of the merger and its
recommendation that the C-Port stockholders approve the merger. See "The
Merger--Interests of C-Port Directors and Officers in the Merger" on page 31.

Opinion of Financial Advisor to C-Port

   Deutsche Bank Securities Inc. has acted as financial advisor to C-Port in
connection with the merger. At the February 17, 2000 meeting of the C-Port
board of directors, Deutsche Bank delivered its oral opinion, subsequently
confirmed in writing as of the same date, to the effect that, as of the date of
such opinion, based upon and subject to the assumptions made, matters
considered and limits of the review undertaken by Deutsche Bank, the exchange
ratio between C-Port and Motorola was fair, from a financial point of view, to
C-Port stockholders.

   The full text of Deutsche Bank's written opinion, dated February 17, 2000
(the "Deutsche Bank Opinion"), which includes the assumptions made, matters
considered and limits on the review undertaken by Deutsche Bank in connection
with its opinion, is attached as Appendix B to this proxy statement/prospectus
and is incorporated herein by reference. C-Port stockholders are urged to read
the Deutsche Bank opinion in its entirety. The summary of the Deutsche Bank
opinion set forth in this proxy statement/prospectus is qualified in its
entirety by reference to the full text of the Deutsche Bank opinion.

   In connection with Deutsche Bank's role as financial advisor to C-Port, and
in arriving at its opinion, Deutsche Bank has, among other things:

  . reviewed certain publicly available financial information and other
    information concerning C-Port and Motorola and certain internal analyses
    and other information furnished to it by C-Port;

  . held discussions with members of the managements of C-Port and Motorola
    regarding the businesses and prospects of their respective companies and
    the joint prospects of a combined enterprise;

  . reviewed the reported prices and trading activity for the common stock of
    Motorola;

  . compared certain financial information for C-Port, and certain financial
    and stock market information for Motorola, with similar information for
    selected companies whose securities are publicly traded;

  . reviewed the financial terms of selected recent business combinations
    which it deemed comparable in whole or in part;

  . reviewed the terms of the merger agreement and certain related documents;
    and

  . performed such other studies and analyses and considered such other
    factors as it deemed appropriate.

   In preparing its opinion, Deutsche Bank did not independently verify any
information concerning C-Port or Motorola, including any financial information,
forecasts or projections, considered in connection with the rendering of its
opinion. Accordingly, for purposes of its opinion, Deutsche Bank assumed and
relied upon the accuracy and completeness of all such information. Deutsche
Bank did not conduct a physical inspection of any of the properties or assets,
and did not prepare or obtain any independent evaluation or appraisal of any of
the assets or liabilities of C-Port or Motorola.

   With respect to the financial forecasts and projections made available to
Deutsche Bank and used in its analysis, Deutsche Bank assumed that they were
reasonably prepared on bases reflecting the best currently available estimates
and judgments of the management of C-Port. In rendering its opinion, Deutsche
Bank expressed no view as to the reasonableness of such forecasts and
projections or the assumptions on which they are based.

   The Deutsche Bank opinion was necessarily based upon economic, market and
other conditions as in effect on, and the information made available to
Deutsche Bank as of, the date of such opinion.

   For purposes of rendering its opinion, Deutsche Bank assumed that, in all
respects material to its analysis:

  . the representations and warranties of C-Port and Motorola contained in
    the merger agreement were and are true and correct;

  . C-Port and Motorola will each perform all of the covenants and agreements
    to be performed by it under the merger agreement and all conditions to
    the obligation of each of C-Port and Motorola to consummate the merger
    will be satisfied without any waiver thereof;

  . all material governmental, regulatory or other approvals and consents
    required in connection with the consummation of the transactions
    contemplated by the merger agreement will be obtained;

  . in connection with obtaining any necessary governmental, regulatory or
    other approvals and consents, or any amendments, modifications or waivers
    to any agreements, instruments or orders to which either C-Port or
    Motorola is a party, no limitations, restrictions or conditions will be
    imposed or amendments, modifications or waivers made that would have a
    material adverse effect on C-Port or Motorola or materially reduce the
    contemplated benefits of the merger; and

  . the shares held in escrow pursuant to the merger agreement and the escrow
    agreement will be released to the stockholders of C-Port on the first
    anniversary of the closing of the transaction without any deduction for
    any indemnification obligation.

   In addition, Deutsche Bank was advised by C-Port, and accordingly assumed
for purposes of its opinion, that the merger will qualify as a reorganization
for federal income tax purposes and that the merger will be accounted for as a
purchase.

   Set forth below is a brief summary of certain financial analyses performed
by Deutsche Bank in connection with its opinion and reviewed with the C-Port
board of directors at its meeting on February 17, 2000.

   Historical Stock Performance. Deutsche Bank reviewed and analyzed recent and
historical market prices for Motorola common stock and compared such market
prices to certain stock market and industry indices. On the basis of this
analysis, Deutsche Bank calculated that, as of the close of trading on February
16, 2000, the per share price of Motorola common stock was

  . 17.8% above its 90-day closing average;

  . 7.8% above its 60-day closing average;

  . 3.4% above its 30-day closing average;

  . 8.4% below its 52-week high; and

  . 133.6% above its 52-week low.

   Analysis of Selected Publicly Traded Companies. Deutsche Bank compared
certain financial information and commonly used valuation measurements for
Motorola and C-Port to corresponding information and

                                       25

measurements for selected groups of publicly traded companies with operations
in markets similar to their own. Those companies are as follows:

</TABLE>

   The financial information and valuation measurements analyzed by Deutsche
Bank included:

  . common equity market value;

  . operating performance;

  . ratios of common equity market value as adjusted for debt and cash
    ("Enterprise Value") to revenues; and

  . ratios of common equity market prices per share ("Equity Value") to
    earnings per share ("EPS").

   To calculate the trading multiples for Motorola and the comparable
companies, Deutsche Bank used publicly available information concerning
historical and projected financial performance, including earnings estimates
reported by the Institutional Brokers Estimate System ("IBES") or by individual
securities firms' equity research departments, including in certain cases
research from Deutsche Bank. IBES is a data service that monitors and publishes
compilations of earnings estimates by selected research analysts regarding
companies of interest to institutional investors.

   The following table summarizes the Enterprise Value to Revenue and EBIT
multiples that Deutsche Bank calculated for C-Port (taking the exchange ratio
into effect), Motorola and their respective comparable companies:

   None of the comparable companies is identical to Motorola or C-Port.
Accordingly, Deutsche Bank believes the analysis of publicly traded comparable
companies is not simply mathematical. Rather, it involves complex
considerations and qualitative judgments, reflected in Deutsche Bank's opinion,
concerning differences in financial and operating characteristics of the
comparable companies and other factors that could affect the public trading
value of the comparable companies.

   Analysis of Selected Precedent Transactions. Deutsche Bank reviewed the
financial terms, to the extent publicly available, of 30 proposed, pending or
completed mergers and acquisition transactions since 1998 involving target
companies in the communications integrated circuit industry.

   For the precedent transactions, Deutsche Bank calculated various financial
multiples based on publicly available information for each of the selected
transactions. Deutsche Bank then compared these financial multiples to the
corresponding financial multiples for the merger, based on the exchange ratio.
Of the precedent transactions, seven had publicly available financial data and
27 had publicly available headcount information, with respect to which Deutsche
Bank calculated the following multiples:

   All multiples for the precedent transactions were based on public
information available at the time of announcement of such transaction, without
taking into account differing market and other conditions during the two-year
period during which the precedent transactions occurred.

                                       27
<PAGE>

   Because the reasons for, and circumstances surrounding, each of the
precedent transactions analyzed were so diverse, and due to the inherent
differences between the operations and financial conditions of Motorola and C-
Port and the companies involved in the precedent transactions, Deutsche Bank
believes that a comparable transaction analysis is not simply mathematical.
Rather, such analysis involves complex considerations and qualitative
judgments, reflected in Deutsche Bank's opinion, concerning differences between
the characteristics of these transactions and the merger that could affect the
value of the subject companies and businesses and Motorola and C-Port.

   Contribution Analysis. Deutsche Bank analyzed the relative contributions of
Motorola and C-Port to the pro forma income statement of the combined company,
based on published earnings estimates for Motorola and management projections
for C-Port, as compared to C-Port's relative ownership of approximately 0.4% of
the outstanding capital of the combined company. This analysis showed that on a
pro forma combined basis (excluding the effect of any synergies that may be
realized as a result of the Merger and any non-recurring expenses relating to
the Merger), based on the 12-month period ending December 31, 2000:

  . Motorola would account for approximately 100.0%, and C-Port would account
    for approximately 0.0%, of the combined company's pro forma revenue; and

  . Motorola would account for approximately 100.4%, and C-Port would account
    for approximately -0.4%, of the combined company's pro forma net income.

   Initial Public Offering Valuation Analysis. Deutsche Bank analyzed various
initial public offering valuation scenarios for C-Port based on the trading
characteristics of the comparable companies and financial projections provided
by management. Deutsche Bank assumed that an initial public offering would not
take place before the first quarter of 2001 and therefore determined that any
estimate of C-Port's value derived from such an analysis was purely
speculative.

   The foregoing summary describes all analyses and factors that Deutsche Bank
deemed material in its presentation to the C-Port board of directors, but is
not a comprehensive description of all analyses performed and factors
considered by Deutsche Bank in connection with preparing its opinion. The
preparation of a fairness opinion is a complex process involving the
application of subjective business judgment in determining the most appropriate
and relevant methods of financial analysis and the application of those methods
to the particular circumstances is not readily susceptible to summary
description. Deutsche Bank believes that its analyses must be considered as a
whole and that considering any portion of such analyses and of the factors
considered without considering all analyses and factors could create a
misleading view of the process underlying the opinion. In arriving at its
fairness determination, Deutsche Bank did not assign specific weights to any
particular analyses.

   In conducting its analyses and arriving at its opinions, Deutsche Bank
utilized a variety of generally accepted valuation methods. The analyses were
prepared solely for the purpose of enabling Deutsche Bank to provide its
opinion to the C-Port board of directors as to the fairness to the stockholders
of C-Port of the exchange ratio. The analyses do not purport to be appraisals
or necessarily reflect the prices at which businesses or securities actually
may be sold, which are inherently subject to uncertainty. In connection with
its analyses, Deutsche Bank made, and was provided by C-Port management with,
numerous assumptions with respect to industry performance, general business and
economic conditions and other matters, many of which are beyond C-Port's or
Motorola's control. Analyses based on estimates or forecasts of future results
are not necessarily indicative of actual past or future values or results,
which may be significantly more or less favorable than suggested by such
analyses. Because such analyses are inherently subject to uncertainty, being
based upon numerous factors or events beyond the control of C-Port, Motorola or
their respective advisors, neither C-Port nor Deutsche Bank nor any other
person assumes responsibility if future results or actual values are materially
different from these forecasts or assumptions.

   The terms of the merger were determined through negotiations between C-Port
and Motorola and were approved by the C-Port board of directors. Although
Deutsche Bank provided advice to C-Port during the

                                       28
<PAGE>

course of these negotiations, the decision to enter into the merger was solely
that of the C-Port board of directors. As described above, the opinion and
presentation of Deutsche Bank to the C-Port board of directors were only one of
a number of factors taken into consideration by the C-Port board of directors
in making its determination to approve the merger agreement and the merger.
Deutsche Bank's opinion was provided to the C-Port board of directors to assist
it in connection with its consideration of the merger agreement and the merger
and does not constitute a recommendation to any stockholder of C-Port as to how
to vote with respect to the merger agreement and the merger.

   C-Port selected Deutsche Bank as financial advisor in connection with the
merger based on Deutsche Bank's qualifications, expertise, reputation and
experience in mergers and acquisitions. C-Port retained Deutsche Bank pursuant
to a letter agreement dated January 4, 2000. As compensation for Deutsche
Bank's services in connection with the merger, C-Port agreed to pay Deutsche
Bank a cash fee of $375,000 upon the delivery of its opinion and an additional
cash fee that would total $3,450,000 if the merger were consummated at the
value implied by the exchange ratio on the announcement date. Regardless of
whether the merger is consummated, C-Port has agreed to reimburse Deutsche Bank
for reasonable fees and disbursements of its counsel and all of its reasonable
travel and other out-of-pocket expenses. C-Port has also agreed to indemnify
Deutsche Bank and certain related persons to the fullest extent lawful against
certain liabilities, including certain liabilities under the federal securities
laws arising out of its engagement or the merger.

   Deutsche Bank is an internationally recognized investment banking firm
experienced in providing advice in connection with mergers and acquisitions and
related transactions. Deutsche Bank has in the past provided investment banking
services to Motorola. Deutsche Bank and its affiliates may actively trade
securities of Motorola for their own account or the account of their customers
and, accordingly, may from time to time hold a long or short position in such
securities.

Accounting Treatment

   We anticipate that the merger will be accounted for as a purchase for
financial reporting and accounting purposes, under generally accepted
accounting principles. Under the purchase method of accounting, the purchase
price paid by Motorola for C-Port (including direct costs of the merger) will
be allocated to the identifiable assets and liabilities of C-Port based upon
the fair value of C-Port's identifiable assets and liabilities as of the
effectiveness of the merger and in process research and development, with the
excess of the purchase price over the fair value of net identifiable assets and
in process research and development being allocated to goodwill. After the
merger, the financial condition and results of operations of C-Port will be
included (but not separately reported) in the consolidated financial condition
and results of operations of Motorola.

Effectiveness of Merger

   The merger will become effective upon the filing of a certificate of merger
with the Delaware secretary of state, or at such later time as is stated in the
certificate of merger. The filing of a certificate of merger will occur as soon
as practicable, but no later than the third business day after satisfaction or
waiver of the conditions to the completion of the merger described in the
merger agreement.

Merger Consideration

   At the effective time of the merger, each issued and outstanding share of C-
Port stock (other than shares as to which dissenters' rights to appraisal have
been perfected) will be converted into the right to receive 0.1022485 of a
share of Motorola common stock for each share of C-Port common stock. As
previously announced by Motorola, on February 29, 2000 Motorola's board of
directors approved a three-for-one stock split of its common stock payable on
June 1, 2000 in the form of a stock dividend to its common stockholders of
record as of the close of business on May 15, 2000. If the effective time of
the merger occurs after May 15, 2000, the 0.1022485 exchange ratio will
automatically adjust under the merger agreement to 0.3067455 to reflect the
stock split.

                                       29
<PAGE>

   Shares of treasury stock held by C-Port will be cancelled. Former C-Port
stockholders will receive cash for any fractional Motorola shares which they
would have otherwise received in the merger. As of the effective time of the
merger, all shares of C-Port stock will no longer be outstanding, will
automatically be cancelled and will cease to exist. At that time, each holder
of a certificate representing shares of C-Port stock (other than shares as to
which dissenters' rights to appraisal have been perfected) will cease to have
any rights as a stockholder except the right to receive Motorola common stock,
the right to any dividends or other distributions in accordance with the merger
agreement and the right to receive cash for any fractional share of Motorola
common stock otherwise issuable in the merger. The exchange ratios were
determined through arm's-length negotiations between Motorola and C-Port.

Treatment of C-Port Stock Options and Restricted Stock

   Under the merger agreement, at the effective time of the merger, Motorola
will assume C-Port's 1997 stock incentive plan and all stock options granted
under the plan to acquire shares of C-Port common stock. Each stock option
under the plan will be converted into a stock option to acquire Motorola common
stock on the same terms and conditions. The number of shares of Motorola common
stock to be subject to any option will be equal to the number of shares of C-
Port common stock subject to that C-Port stock option multiplied by the
0.1022485 exchange ratio and rounded down to the nearest whole share. The
exchange ratio will be adjusted to give effect to any reclassification, stock
split, stock dividend, reorganization or other similar exchange with respect to
Motorola or C-Port common stock occurring before the merger. The exercise price
per share of Motorola common stock under any stock option will be equal to the
exercise price per share of C-Port common stock subject to that C-Port stock
option divided by the exchange ratio and rounded up to the nearest whole cent.
The merger agreement provides that, prior to the effective time of the merger,
the C-Port board of directors will adopt, by resolution, an amendment, subject
to C-Port stockholder approval (as described in the following sentence), to the
C-Port 1997 stock incentive plan, the form of which will be approved by
Motorola, to provide that one-half of the C-Port stock options that are
unvested as of the effective time of the merger and held by any person
providing services to C-Port at the effective time of the merger shall become
fully vested and exercisable at the effective time of the merger and the other
one-half of the C-Port stock options shall become fully vested over the 12-
month period following the effective date of the merger on a pro-rata basis. C-
Port will also request, in a separate written action, that its stockholders
consent to the acceleration with respect to those option holders who may be
disqualified individuals within the meaning of Section 280G of the Internal
Revenue Code. This consent is expected to be obtained in a manner consistent
with the stockholder approval requirements of Section 280G of the Internal
Revenue Code.

   Pursuant to their restricted stock agreements with C-Port, in the event of a
transaction such as the merger, holders of C-Port restricted stock are entitled
to acceleration of one-half of the unvested portion of their restricted stock
and vesting of the remaining one-half over the 12-month period following such
transaction. Prior to the stockholder approval described in the following
sentence, holders of C-Port restricted stock who may be disqualified
individuals within the meaning of Section 280G of the Internal Revenue Code may
elect to waive this preexisting right to acceleration of vesting upon the
merger. Thereafter, C-Port will request, in a separate written action, the
approval of its stockholders of the reinstatement of any waived acceleration of
vesting of the C-Port restricted stock in a manner intended to comply with the
stockholder approval requirements of Section 280G of the Internal Revenue Code.

   As long as the approval requirements of Section 280G of the Internal Revenue
Code are complied with, the value of the acceleration of the vesting of C-Port
stock options and restricted stock should not be considered an "excess
parachute payment" subject to Sections 280G and 4999 of the Internal Revenue
Code.

   No later than 15 calendar days after the effective time of the merger,
Motorola will prepare and file with the SEC a registration statement on Form S-
8 under the Securities Act of 1933 registering the shares of Motorola common
stock subject to the assumed C-Port stock options. That registration statement
will be kept effective (and the current status of the prospectus required by
the SEC shall be maintained in accordance with the requirements of the
Securities Act of 1933 and the Securities Exchange Act of 1934) for so long as
any assumed C-Port options remain outstanding. See "The Merger Agreement--
Treatment of C-Port Stock Options" on page 40.

Interests of C-Port Directors and Officers in the Merger

   In considering the recommendation of the C-Port board of directors in favor
of the merger agreement and the merger, you should be aware that certain
directors and executive officers of C-Port have interests in the merger that
are different from or in addition to, the interests of stockholders of C-Port.
These interests relate to or arise from, among other things:

  . the continued indemnification of current directors and officers of C-
    Port; and

  . the retention of certain current officers of C-Port as employees of
    Motorola following the merger.

   These interests are described below, to the extent material, and except as
described below, those persons have, to the knowledge of C-Port, no material
interest in the merger apart from those of stockholders generally. The C-Port
board of directors was aware of, and considered the interests of, themselves
and C-Port's executive officers in approving the merger agreement and the
merger. You should also read the section entitled "Certain Information
Concerning C-Port" beginning on page 59.

   Indemnification. The merger agreement provides that Motorola will, for a
period of two years following the effective date of the merger, fulfill and
honor in all respects the obligations of C-Port to indemnify each person who
is or was a director or officer of C-Port pursuant to any indemnification
provision contained in C-Port's charter or by-laws as each was in effect on
the date of the merger agreement.

   Ownership and Voting of C-Port Stock. As of March 23, 2000, the directors
and executive officers of C-Port collectively owned directly approximately
4,330,000 shares of C-Port common stock and 377,518 shares of C-Port preferred
stock. As of March 23, 2000, directors and officers of C-Port and their
affiliates may be deemed to have beneficial ownership of approximately
4,330,000 shares of C-Port's issued and outstanding common stock, and
9,253,554 shares of C-Port's issued and outstanding preferred stock. These
officers and directors may be deemed to have beneficial ownership either by
themselves or with others. Certain of the C-Port directors have agreed to vote
their issued and outstanding shares over which they have voting control in
favor of the merger agreement and the merger. See also "Certain Information
Concerning C-Port" on page 59.

   Employment Agreements. It is a condition to the merger that employment
agreements be entered into between Motorola and each of Laurence G. Walker,
David Husak, Peter Morris, Richard Hollingsworth, Kurt Hoff, Clint Ramsay and
John Burnham, each a current employee of C-Port. The term of each employment
agreement will be two years from the effective date of the merger, except for
Dr. Walker's employment agreement, which will have a term of three years
following the effective date of the merger. If, before the end of the
applicable term, the employee is terminated without cause, or the employee
terminates employment for good reason, he will be entitled to a severance
payment from Motorola equal to 50% of the annual salary that would have been
payable under the employment agreement. Each employment agreement provides
that Motorola will grant to the applicable employee options to purchase shares
of Motorola common stock. The Motorola stock options, the exercise price of
which will be set as of the date the option certificate is issued to each
applicable employee, will vest over a four year period, with 25% of the
options vesting on each of the first four anniversaries of the grant date of
the stock options. In order to exercise the options, the employee must be
employed by Motorola or its C-Port subsidiary on the date of exercise. In
addition, each employment agreement requires Motorola to grant shares of
Motorola restricted stock to the applicable employee within 30 days after such
employee's first date of employment under the employment agreement. Each
employee's rights in the restricted stock will vest on the fourth anniversary
of the grant date. Finally, each employment agreement requires that Motorola
pay to the applicable employee a retention bonus within 30 days after the
employee completes 24 months of consecutive employment with Motorola or with
C-Port following the merger. Dr. Walker's employment agreement will require
that he return the retention bonus paid to him if he terminates his employment
with C-Port voluntarily prior to the end of the three year term of his
employment agreement. Each employment agreement will also contain non-
competition and non-solicitation covenants.

Concerning C-Port" on page 59.

Material Federal Income Tax Consequences of the C-Port Merger

   In the opinion of Winston & Strawn, tax counsel to Motorola, and Hale and
Dorr LLP, tax counsel to C-Port, the following is a summary of the material
United States federal income tax consequences of the merger to C-Port
stockholders who exchange their C-Port shares for Motorola shares and, as
applicable, cash in lieu of fractional shares of Motorola stock pursuant to the
merger agreement. This discussion addresses only stockholders who hold their C-
Port shares as a capital asset and does not address all of the United States
federal income tax consequences that may be relevant to particular stockholders
in light of their individual circumstances or to stockholders who are subject
to special rules (including, without limitation, financial institutions, tax-
exempt organizations, insurance companies, dealers in securities or foreign
currencies, foreign holders, persons who hold their C-Port shares as a hedge
against currency risk, a constructive sale, or conversion transaction, or
holders who acquired their shares pursuant to the exercise of an employee stock
options or otherwise as compensation). The following summary is not binding on
the Internal Revenue Service or a court. It is based upon the Internal Revenue
Code, laws, regulations, rulings, and decisions in effect on the date hereof,
all of which are subject to change, possibly with retroactive effect. Tax
consequences under state, local, and foreign laws are not addressed.

   The following discussion is not intended to be a complete analysis
or description of all potential United States federal income tax consequences
or any other tax consequences of the merger. In addition, the discussion does
not address tax consequences which may vary with, or are contingent on, your
individual circumstances. C-Port stockholders are strongly urged to consult
their own tax advisors as to the specific tax consequences to them of the
merger, including the applicability and effect of federal, state, local, and
foreign income and other tax laws on their particular circumstances.

   No ruling has been, or will be, sought from the Internal Revenue Service as
to the United States federal income tax consequences of the merger. It is a
condition to the consummation of the merger that Motorola receive an opinion
from its counsel, Winston & Strawn, and that C-Port receive an opinion from its
counsel, Hale and Dorr LLP, stating that the merger will be treated for United
States federal income tax purposes as a reorganization within the meaning of
Section 368(a) of the Internal Revenue Code. The issuance of such opinions will
be conditioned on customary assumptions and representations made by Motorola,
CP Acquisition Corp. and C-Port. An opinion of counsel is not binding on the
Internal Revenue Service or a court. As a result, neither Motorola nor C-Port
can assure you that the tax considerations and opinions contained in this
discussion will not be challenged by the Internal Revenue Service or sustained
by a court if challenged by the Internal Revenue Service.

   As a result of the merger qualifying as a reorganization within the meaning
of Section 368(a) of the Internal Revenue Code, C-Port stockholders who
exchange their C-Port shares for Motorola shares will not recognize gain or
loss for United States federal income tax purposes, except with respect to
cash, if any, they receive in lieu of fractional shares of Motorola stock. The
aggregate tax basis of a C-Port stockholder in the Motorola shares received in
exchange for C-Port shares pursuant to the merger will be the same as such
holder's aggregate tax basis in the C-Port shares surrendered in the merger,
decreased by the amount of any tax basis allocable to any fractional share
interest for which cash is received. The holding period of the Motorola shares
received in the merger by a C-Port stockholder will include the holding period
of the C-Port shares surrendered in the merger.

   C-Port stockholders who receive cash in lieu of fractional shares of
Motorola stock in the merger generally will recognize gain or loss equal to the
difference between the amount of cash received and their tax basis in C-Port
shares that is allocable to the fractional shares. The gain or loss generally
will be capital gain or loss. In the case of an individual stockholder, capital
gain is subject to a maximum tax rate of 20% if the individual held his or her
C-Port shares for more than 12 months at the effective time of the merger. The
deductibility of capital losses is subject to limitations for both individuals
and corporations.

                                       32
<PAGE>

   C-Port stockholders who exchange C-Port shares for Motorola shares should be
treated as receiving the escrowed Motorola shares at the time of the merger and
should be treated as owners of such shares. Until such shares are released, the
interim basis of the Motorola stock received by a C-Port stockholder will be
determined as if such stockholder received the maximum number of Motorola
shares. No federal income tax consequences should result from the receipt of
any shares upon the termination of the escrow. It is the Internal Revenue
Service's position that the former C-Port stockholders would recognize capital
gain or loss to the extent the escrowed Motorola shares are used to satisfy a
claim. The amount of the gain or loss recognized should equal the difference
between the stockholder's basis in the escrowed Motorola shares used to satisfy
the claim and the fair market value of those shares. The value of such returned
shares will be added back to the tax basis of the Motorola stock retained by
the stockholder.

   If the Internal Revenue Service were to successfully challenge the
"reorganization" status of the merger, each C-Port stockholder would recognize
taxable gain (or loss) with respect to the C-Port stock surrendered, measured
by the difference between (i) the fair market value, as of the time of the
merger, of the Motorola common stock received in the merger, and (ii) the
stockholder's tax basis in the C-Port stock surrendered therefor in the merger.
In such event, a stockholder's aggregate basis in the Motorola common stock so
received would equal its fair market value as of the time of the merger and the
holding period for such stock would begin the day after the merger.

   C-Port stockholders will be required to attach a statement to their tax
returns for the year of the merger that contains the information listed in
Treasury Regulation Section 1.368-3(b). Such statement must include the
stockholder's tax basis in the stockholder's C-Port stock and a description of
the Motorola common stock received therefor. C-Port stockholders are urged to
consult their tax advisors with respect to this statement and any other tax
reporting requirements.

   The opinions described above do not apply to stockholders who exercise
appraisal rights. A C-Port stockholder who exercises appraisal rights with
respect to the merger and receives cash for shares of C-Port stock will
generally recognize capital gain (or loss) measured by the difference between
the amount of cash received and the stockholder's basis in those shares,
provided that the payment is not treated as a dividend pursuant to Section 302
of the Internal Revenue Code or otherwise. A sale of shares based on an
exercise of appraisal rights will not be treated as a dividend if the
stockholder exercising appraisal rights owns no shares of C-Port immediately
after the merger, after giving effect to the constructive ownership rules
pursuant to the Internal Revenue Code. The capital gain or loss will be long-
term capital gain or loss if the holder's holding period for the shares is more
than one year.

   A noncorporate C-Port stockholder may be subject to backup withholding at a
rate of 31% on cash payments received in lieu of a fractional share of Motorola
stock or upon the exercise of appraisal rights. Backup withholding will not
apply, however, to a stockholder who (1) furnishes a correct taxpayer
identification number and certifies that it is not subject to backup
withholding on the substitute W-9 or successor form included in the letter of
transmittal to be delivered to C-Port stockholders following the completion of
the merger, (2) provides a certification of foreign status on Form W-8BEN or
successor form, or (3) is otherwise exempt from backup withholding.

Regulatory Matters

   Under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, the merger
may not be consummated until notifications have been furnished to the Federal
Trade Commission and the Antitrust Division of the Department of Justice and
specified waiting period requirements have been satisfied. C-Port and Motorola
each filed a pre-merger notification and report form with the FTC and the
Antitrust Division on or about March 17, 2000 and March 13, 2000, respectively.

                                       33
<PAGE>

   At any time before the effective time of the merger, the FTC, the Antitrust
Division or a private person or entity could seek under antitrust laws, among
other things, to enjoin the merger and, any time after the effective time of
the merger, to cause Motorola to divest itself, in whole or in part, of the
surviving corporation of the merger or of certain businesses conducted by the
surviving corporation. There can be no assurance that a challenge to the merger
will not be made or that, if such a challenge is made, Motorola will prevail.

Statutory Appraisal Rights

   The Delaware General Corporation Law grants appraisal rights in the merger
to the holders of C-Port common stock and preferred stock. Under the Delaware
General Corporation Law, C-Port stockholders may object to the merger, and
demand in writing that C-Port pay the fair value of their shares. Fair value
takes into account all relevant factors but excludes any appreciation or
depreciation in anticipation of the applicable merger. Stockholders who elect
to exercise appraisal rights must comply with all of the procedures to preserve
those rights. We have attached a copy of Section 262 of the Delaware General
Corporation Law (which sets forth the appraisal rights) as Appendix D to this
proxy statement/prospectus.

   Section 262 sets forth the required procedure a stockholder requesting
appraisal must follow. Making sure that you actually perfect your appraisal
rights can be complicated. The procedural rules are specific and must be
followed completely. Failure to comply with the procedure may cause a
termination of your appraisal rights. We are providing you only a summary of
your rights and the procedure. The following information is qualified in its
entirety by the provisions of Section 262, a copy of which is attached as
Appendix D to this proxy statement/prospectus. Please review Section 262 for
the complete procedure. C-Port will not give you any notice other than as
described in this proxy statement/prospectus and as required by the Delaware
General Corporation Law.

Appraisal Rights Procedures

   If you are a C-Port stockholder and you wish to exercise your appraisal
rights, you must satisfy the provisions of Section 262 of the Delaware General
Corporation Law. Section 262 requires the following:

   You Must Make a Written Demand for Appraisal. You must deliver a written
demand for appraisal to C-Port before the vote on the merger agreement and the
merger is taken at the special meeting. This written demand for appraisal must
be separate from your proxy. In other words, a vote against the C-Port merger
agreement and the merger will not alone constitute demand for appraisal.

   You Must Refrain from Voting for Approval of the Merger. You must not vote
for approval of the merger agreement and the merger. If you vote, by proxy or
in person, in favor of the merger agreement and the merger, this will terminate
your right to appraisal. You can also terminate your right to appraisal if you
return a signed proxy and (1) fail to vote against approval of the merger
agreement and the merger or (2) fail to note that you are abstaining from
voting. Your appraisal rights will be terminated even if you previously filed a
written demand for appraisal.

   You Must Continuously Hold Your C-Port Shares. You must continuously hold
your shares of C-Port stock, from the date you make the demand for appraisal
through the closing of the merger. If you are the record holder of C-Port stock
on the date the written demand for appraisal is made but thereafter transfer
the shares prior to the merger, you will lose any right to appraisal in respect
of those shares. You should read the paragraphs below for more details on
making a demand for appraisal.

   A written demand for appraisal of C-Port stock is only effective if it is
signed by, or for, the stockholder of record who owns such shares at the time
the demand is made. The demand must be signed as the stockholder's name appears
on his/her/its stock certificate(s). If you are the beneficial owner of C-Port
stock, but not the stockholder of record, you must have the stockholder of
record sign a demand for appraisal.


                                       34
<PAGE>

   If you own C-Port stock in a fiduciary capacity, such as a trustee, guardian
or custodian, you must disclose the fact that you are signing the demand for
appraisal in that capacity.

   If you own C-Port stock with more than one person, such as in a joint
tenancy or tenancy in common, all of the owners must sign, or have signed for
them, the demand for appraisal. An authorized agent, which could include one or
more of the joint owners, may sign the demand for appraisal for a stockholder
of record; however, the agent must expressly disclose who the stockholder of
record is and that the agent is signing the demand as that stockholder's agent.

   If you are a C-Port stockholder who elects to exercise appraisal rights, you
should mail or deliver a written demand to:

  C-Port Corporation
  One High Street
  North Andover, Massachusetts 01845
  Attention: Secretary

   It is important that C-Port receive all written demands before the vote
concerning the merger agreement and the merger is taken at the special meeting.
As explained above, this written demand should be signed by, or on behalf of,
the stockholder of record. The written demand for appraisal should specify the
stockholder's name and mailing address, the number of shares of stock owned,
and that the stockholder is thereby demanding appraisal of that stockholder's
shares.

   If you fail to comply with any of these conditions and the merger becomes
effective, you will only be entitled to receive the merger consideration
provided in the merger agreement.

   Written Notice. Within ten days after the closing of the merger, C-Port must
give written notice that the merger has become effective to each stockholder
who has fully complied with the conditions of Section 262.

   Petition with the Chancery Court. Within 120 days after the merger, either
the surviving corporation or any stockholder who has complied with the
conditions of Section 262, may file a petition in the Delaware Court of
Chancery. This petition should request that the chancery court determine the
value of the shares of stock held by all of the stockholders who are entitled
to appraisal rights. If you intend to exercise your rights of appraisal, you
should file such a petition in the chancery court. C-Port has no intention at
this time to file such a petition. Because C-Port has no obligation to file
such a petition, if you do not file such a petition within 120 days after the
closing, you will lose your rights of appraisal.

   Withdrawal of Demand. If you change your mind and decide you no longer want
appraisal rights, you may withdraw your demand for appraisal rights at any time
within 60 days after the closing of the merger. You may also withdraw your
demand for appraisal rights after 60 days after the closing of your merger, but
only with the written consent of C-Port. If you effectively withdraw your
demand for appraisal rights, you will receive the merger consideration provided
in your merger agreement.

   Request for Appraisal Rights Statement. If you have complied with the
conditions of Section 262, you are entitled to receive a statement from C-Port.
This statement will set forth the number of shares that have demanded appraisal
rights, and the number of stockholders who own those shares. In order to
receive this statement, you must send a written request to C-Port within 120
days after the merger. After the merger, C-Port has ten days after receiving a
request to mail you the statement.

   Chancery Court Procedures. If you properly file a petition for appraisal in
the chancery court and deliver a copy to C-Port, C-Port will then have 20 days
to provide the chancery court with a list of the names and addresses of all
stockholders who have demanded appraisal rights and have not reached an
agreement with C-Port as to the value of their shares. The chancery court will
then send notice to all of the stockholders who have demanded appraisal rights.
If the chancery court thinks it is appropriate, it has the power to conduct a

                                       35
<PAGE>

hearing to determine whether the stockholders have fully complied with Section
262 of the Delaware General Corporation Law and whether they are entitled to
appraisal rights under that section. The chancery court may also require you to
submit your stock certificates to the Registry in Chancery so that it can note
on the certificates that an appraisal proceeding is pending. If you do not
follow the chancery court's directions, you may be dismissed from the
proceeding.

   Appraisal of Shares. After the chancery court determines which stockholders
are entitled to appraisal rights, the chancery court will appraise the shares
of stock. To determine the fair value of the shares, the chancery court will
consider all relevant factors except for any appreciation or depreciation due
to the anticipation or accomplishment of the merger. After the chancery court
determines the fair value of the shares, it will direct C-Port to pay that
value to the stockholders who are entitled to appraisal rights. The chancery
court can also direct C-Port to pay interest, simple or compound, on that value
if the chancery court determines that interest is appropriate. In order to
receive your fair value for your shares, you must then surrender your stock
certificates to C-Port.

   The chancery court could determine that the fair value of shares of stock is
more than, the same as, or less than the merger consideration. In other words,
if you demand appraisal rights, you could receive less consideration than you
would under the merger agreement. You should also be aware that an opinion of
an investment banking firm that the merger is fair is not an opinion that the
merger consideration is the same as the fair value under Section 262.

   Costs and Expenses of Appraisal Proceeding. The costs and expenses of the
appraisal proceeding may be assessed against C-Port and the stockholders
participating in the appraisal proceeding, as the chancery court deems
equitable under the circumstances. You can request that the chancery court
determine the amount of interest, if any, C-Port should pay on the value of
stock owned by stockholders entitled to the payment of interest. You may also
request that the chancery court allocate the expenses of the appraisal action
incurred by any stockholder pro rata against the value of all of the shares
entitled to appraisal.

   Loss of Stockholder's Rights. If you demand appraisal rights, after the
closing of the merger you will not be entitled to:

  . vote your shares of stock, for any purpose, for which you have demanded
    appraisal rights;

  . receive payment of dividends or any other distribution with respect to
    such shares, except for dividends or distributions, if any, that are
    payable to holders of record as of a record date prior to the effective
    time of the merger; or

  . receive the payment of the consideration provided for in the merger
    agreement (unless you properly withdraw your demand for appraisal).

   If no petition for an appraisal is filed within 120 days after the closing
of the merger, your right to an appraisal will cease. You may withdraw your
demand for appraisal and accept the merger consideration by delivering to C-
Port a written withdrawal of your demand, except that (1) any attempt to
withdraw made more than 60 days after the closing of the merger will require
the written approval of C-Port, and (2) an appraisal proceeding in the chancery
court cannot be dismissed unless the chancery court approves.

   If you fail to comply strictly with the procedures described above you will
lose your appraisal rights. Consequently, if you wish to exercise your
appraisal rights, we strongly urge you to consult a legal advisor before
attempting to exercise your appraisal rights.

Resale of Motorola Common Stock

   The issuance of the shares of Motorola common stock to C-Port stockholders
in the merger will have been registered under the Securities Act of 1933, as
amended. Upon issuance, these shares may be traded freely and without
restriction by those stockholders not deemed to be "affiliates" of C-Port as
that term is defined for

                                       36
<PAGE>

purposes of Rule 145 under the Securities Act. An "affiliate" of C-Port for
this purpose is a person or entity that directly or indirectly, through one or
more intermediaries, controls, is controlled by, or is under common control
with, C-Port. Any subsequent transfer by an affiliate of C-Port must be one
permitted by the resale provisions of Rule 145 promulgated under the Securities
Act (or Rule 144 promulgated under the Securities Act, in the case of any
persons who become affiliates of Motorola) or as otherwise permitted under the
Securities Act. These restrictions are expected to apply to the directors,
executive officers and holders of 10% or more of the C-Port shares (as well as
to certain other related individuals or entities).

   This proxy statement/prospectus does not cover resales of Motorola common
stock to be received by the stockholders of C-Port in the merger, and no person
is authorized to make any use of this proxy statement/prospectus in connection
with any such resale.

Management and Operations of C-Port after the Merger

   After the merger, Motorola expects to operate C-Port as part of Motorola's
Networking and Computing Systems Group within Motorola's Semiconductor Products
Sector. Motorola expects that Laurence G. Walker will continue as C-Port's
President and Chief Executive Officer after the merger and that other members
of current C-Port management will remain at C-Port. The headquarters of C-Port
is expected to remain at C-Port's current headquarters in North Andover,
Massachusetts.

                              THE MERGER AGREEMENT

   The following is a summary, and is qualified in its entirety by, the terms
of the merger agreement. The following does not purport to describe all the
terms of the merger agreement. The full text of the merger agreement is
attached as Appendix A to this proxy statement/prospectus and is incorporated
herein by reference. We urge you to read the merger agreement in its entirety.

The Merger

   Following the adoption of the merger agreement and approval of the merger by
C-Port stockholders and the satisfaction or waiver of the other conditions to
the merger, CP Acquisition Corp., a wholly owned subsidiary of Motorola, will
merge into C-Port. C-Port will survive the merger as a wholly owned subsidiary
of Motorola. If all conditions to the merger are satisfied or waived, the
merger will become effective at the time of the filing by the surviving
corporation of a duly executed certificate of merger with the Delaware
secretary of state or at such other time as may be specified in the certificate
of merger.

   In addition, following the merger:

  . the charter and by-laws of CP Acquisition Corp. will become the charter
    and by-laws of C-Port; and

  . the directors and officers of CP Acquisition Corp. will become the
    directors and officers of C-Port.

Treatment of C-Port Common Stock

   The merger agreement provides that, at the effective time of the merger,
generally, each issued and outstanding share of C-Port common stock will be
converted into the right to receive the following merger consideration:

  . in the event that at least 55% of C-Port's preferred stockholders decide
    to be treated as if they had converted each of their shares of preferred
    stock into C-Port common shares immediately prior to the merger,
    0.1022485 of a share of Motorola common stock for each share of C-Port
    common stock; and

  . in the event that at least 55% of C-Port's preferred stockholders decide
    that the merger should be treated as a "liquidation, dissolution or
    winding up" of C-Port as described in C-Port's charter, 0.2446233 of a
    share of Motorola common stock for each share of C-Port common stock as
    of February 17, 2000.

See "--Treatment of C-Port Preferred Stock" on page 38. All shares of C-Port
common stock held in treasury by C-Port will be cancelled without conversion.
Motorola will adjust the exchange ratio to provide for any reclassification,
stock split, stock dividend, reorganization or other similar exchange with
respect to Motorola or C-Port common stock occurring before the merger.

   Because the holders of at least 55% of the issued and outstanding shares of
C-Port preferred stock approved and adopted, by written consent in lieu of a
meeting, a resolution electing not to treat the merger as a "liquidation,
dissolution or winding up" of C-Port under the provisions of C-Port's charter,
based on an exchange ratio of 0.1022485, and based on the number of shares of
C-Port common stock and options and warrants to purchase C-Port common stock
outstanding as of March 23, 2000, a total of approximately 2,817,916 shares of
Motorola common stock will be issued to the holders of C-Port common stock in
the merger, assuming that none of the outstanding stock options under C-Port's
1997 stock incentive plan are exercised prior to the effective time of the
merger. If the merger occurs after May 15, 2000, the record date for the three-
for-one stock split of Motorola's common stock approved by the Motorola board
of directors on February 29, 2000, approximately 8,453,958 shares of Motorola
common stock will be issued to the holders of C-Port common stock in the
merger, assuming that none of the outstanding stock options under C-Port's 1997
stock incentive plan are exercised prior to the effective time of the merger.

Treatment of C-Port Preferred Stock

   The merger agreement provides that the per share merger consideration to be
paid to holders of C-Port preferred stock depends upon whether or not the
holders of 55% of the preferred stock of C-Port voting as a single class on an
as converted basis elect not to treat the merger as a "liquidation, dissolution
or winding up"

                                       38
<PAGE>

of C-Port for purposes of Article Fourth of C-Port's charter. The holders of
approximately 64% of the issued and outstanding shares of C-Port preferred
stock, voting as a single class, approved and adopted, by a written consent in
lieu of a meeting dated March 14, 2000, a resolution electing not to treat the
merger as a "liquidation, dissolution or winding up" of C-Port.

   If the holders of 55% of the preferred stock of C-Port voting as a single
class had not enacted the proposal that the merger not be treated as a
"liquidation, dissolution or winding up" of C-Port, then the preferred
stockholders would have received the following consideration:

  . in the case of each share of Series A preferred stock of C-Port:

   . a fraction of a share of Motorola common stock equal to (a) the Series
     A Convertible Preferred Liquidation Amount (as defined in the C-Port
     charter) divided by $147.875, and divided by (b) the aggregate number
     of shares of Series A preferred stock outstanding at the effective time
     and (y) a fraction of a share of Motorola common stock equal to (A) the
     difference of three times the Original Purchase Price (as defined in
     the C-Port charter) of the Series A preferred stock minus the Series A
     Convertible Preferred Liquidation Amount (as defined in the C-Port
     charter), divided by $147.875, divided by (B) the number of outstanding
     shares of Series A preferred stock of C-Port at the effective time of
     the merger;

  . in the case of each share of Series B preferred stock of C-Port:

   . a fraction of a share of Motorola common stock equal to (a) the Series
     B Convertible Preferred Liquidation Amount (as defined in the C-Port
     charter) divided by $147.875, and divided by (b) the aggregate number
     of shares of Series B preferred stock of C-Port outstanding at the
     effective time and (y) a fraction of a share of Motorola common stock
     equal to (A) the difference of three times the Original Purchase Price
     (as defined in the C-Port charter) of the Series B preferred stock
     minus the Series B Convertible Preferred Liquidation Amount (as defined
     in the C-Port charter), divided by $147.875, divided by (B) the number
     of outstanding shares of Series B preferred stock of C-Port at the
     effective time of the merger; and

  . in the case of each share of Series C preferred stock of C-Port:

   . a fraction of a share of Motorola common stock equal to (a) the Series
     C Convertible Preferred Liquidation Amount (as defined in the C-Port
     charter) divided by $147.875, and divided by (b) the aggregate number
     of shares of Series C preferred stock of C-Port outstanding at the
     effective time and (y) a fraction of a share of Motorola common stock
     equal to (A) the difference of three times the Original Purchase Price
     (as defined in the C-Port charter) of the Series C preferred stock
     minus the Series C Convertible Preferred Liquidation Amount (as defined
     in the C-Port charter), divided by $147.875, divided by (B) the number
     of outstanding shares of Series C preferred stock of C-Port at the
     effective time of the merger.

Because the holders of at least 55% of the issued and outstanding shares of C-
Port preferred stock have elected not to treat the merger as a "liquidation,
dissolution or winding up" of C-Port under the provisions of C-Port's charter,
and have further elected, immediately prior to the effective time, to
voluntarily convert each outstanding share of C-Port preferred stock into C-
Port common stock, the preferred stockholders will become holders of C-Port
common stock immediately prior to the merger and will therefore receive the
same consideration as the C-Port common stockholders. See "--Treatment of C-
Port Common Stock" on page 38. If the preferred stockholders had not elected to
convert their shares of C-Port preferred stock into C-Port common stock
immediately prior to the merger, the merger agreement provides that the C-Port
preferred stockholders would have received the following merger consideration:

  . in the case of each share of Series A preferred stock of C-Port:

   . a fraction of a share of Motorola common stock equal to 0.1022485 times
     the number of shares of common stock of C-Port into which such share of
     Series A preferred stock is then convertible pursuant to the C-Port
     charter;

                                       39
<PAGE>

  . in the case of each share of Series B preferred stock of C-Port:

   . a fraction of a share of Motorola common stock equal to 0.1022485 times
     the number of shares of common stock of C-Port into which such share of
     Series B preferred stock is then convertible pursuant to the C-Port
     charter; and

  . in the case of each share of Series C preferred stock of C-Port:

   . a fraction of a share of Motorola common stock equal to 0.1022485 times
     the number of shares of common stock of C-Port into which such share of
     Series C preferred stock is then convertible pursuant to the C-Port
     charter.

   The merger agreement requires Motorola to adjust the exchange ratio to
provide for any reclassification, stock split, stock dividend, reorganization
or other similar exchange with respect to Motorola or C-Port common stock
occurring before the merger.

Treatment of C-Port Stock Options

   At the effective time of the merger, Motorola will assume each unexpired and
unexercised option to purchase shares of C-Port common stock under C-Port's
1997 stock incentive plan and convert it into an option to purchase shares of
Motorola common stock subject to the same terms and conditions as were
applicable prior to the effective time of the merger. The number of shares of
Motorola common stock to be subject to each C-Port stock option assumed by
Motorola will be equal to the number of shares of C-Port common stock subject
to the C-Port stock option immediately prior to the merger multiplied by the
0.1022485 exchange ratio. Any fractional shares of Motorola common stock
resulting from such adjustment will be rounded down to the nearest whole number
of shares of Motorola common stock. The exercise price per share of Motorola
common stock issuable under each C-Port stock option will equal the per share
exercise price of the C-Port common stock specified under the C-Port option
divided by the 0.1022485 exchange ratio. The exercise price will be rounded up
to the nearest whole cent. Motorola will adjust this exchange ratio to provide
for any reclassification, stock split, stock dividend, reorganization or other
similar exchange with respect to Motorola or C-Port common stock occurring
before the merger.

   At the effective time of the merger, Motorola will take all necessary
actions to assume C-Port's 1997 stock incentive plan. No later than 15 calendar
days following the effective time of the merger, Motorola will prepare and file
with the SEC a registration statement on Form S-8 registering the shares of
Motorola common stock subject to the assumed C-Port stock options. That
registration statement will be kept effective (and the current status of the
prospectus required by that registration statement will be maintained in
accordance with the relevant requirements of the Securities Act and the
Exchange Act) at least for so long as any assumed C-Port stock options remain
outstanding.

Treatment of C-Port Restricted and Founders Stock

   At the effective time of the merger, each outstanding restricted share of C-
Port common stock issued by C-Port pursuant to a restricted stock agreement or
a founders stock agreement will be converted into restricted shares of Motorola
common stock based on the 0.1022485 exchange ratio and will remain subject to
the same terms, forfeiture and repurchase restrictions and vesting schedules as
were applicable prior to the effective time of the merger, unless otherwise
agreed to by Motorola and the holder of such shares. Motorola will adjust the
exchange ratio to provide for any reclassification, stock split, stock
dividend, reorganization or other similar exchange with respect to Motorola or
C-Port common stock occurring before the merger. Motorola will assume any
rights C-Port held prior to the effective time of the merger to repurchase
these unvested shares.

Fractional Shares

   Motorola will not issue any fractional shares in the merger. In lieu of any
fractional Motorola shares, each C-Port stockholder who would otherwise have
been entitled to a fraction of a Motorola share pursuant to the merger
agreement will be paid an amount in cash, without interest, equal to such
holder's proportionate interest

                                       40
<PAGE>

in the net proceeds from the sale or sales in the open market of the aggregate
fractional Motorola shares, if any, that would have been issued in the merger.
Harris Trust and Savings Bank or another bank or trust company selected by
Motorola to act as its exchange agent will sell such aggregate fractional
shares at the then prevailing prices on the New York Stock Exchange. These
sales will be executed through one or more member firms of the New York Stock
Exchange and will be executed in round lots to the extent practicable. C-Port
will pay all commissions, transfer taxes and other out-of-pocket transaction
costs of Motorola's exchange agent, including the expenses and compensation of
Motorola's exchange agent, incurred in connection with the sale of fractional
shares.

Exchange of Certificates

   Promptly after the merger, Harris Trust and Savings Bank, Motorola's
exchange agent, will mail to each holder of record of certificates that
immediately prior to the merger represented outstanding C-Port shares both a
letter of transmittal and instructions for surrendering their C-Port stock
certificates. The letter of transmittal and instructions are for use by each
holder of record in surrendering C-Port stock certificates in exchange for
certificates representing that number of Motorola shares and cash for any
fractional shares thereof to which such holder would otherwise be entitled. We
request that you not surrender your C-Port stock certificates for exchange
until you receive the letter of transmittal and instructions. At and after the
merger and until so surrendered, the C-Port stock certificates will represent
only the right to receive the consideration described above. No dividends or
other distributions declared or made after the merger with respect to Motorola
shares will be paid to the holder of record of any unsurrendered C-Port stock
certificates. However, following surrender of any such C-Port stock
certificates, the holder of record will be paid, without interest, with respect
to each whole share of Motorola common stock which such person is entitled to
receive in the merger, (1) the amount of any dividends or other distributions
with a record date after the merger but a payment prior to surrender of such C-
Port stock certificates and (2) at the appropriate payment date, the amount of
dividends or distributions with a record date after the merger but prior to
surrender of such C-Port stock certificates and a payment after the surrender
of such C-Port stock certificates. No transfers of C-Port shares shall be made
after the merger.

   If any C-Port stock certificate is lost, stolen or destroyed, a C-Port
stockholder must provide an appropriate affidavit of that fact. Motorola may
require a C-Port stockholder to deliver a bond as indemnity against any claim
that may be made against Motorola with respect to any lost, stolen or destroyed
certificate.

Listing of Motorola Common Stock

   Motorola has agreed to prepare and submit to the New York Stock Exchange a
listing application covering the shares of Motorola common stock to be issued
in the merger and to use reasonable best efforts to cause such shares to be
approved for listing on such exchange, subject to official notice of issuance,
prior to the effective time of the merger. Approval for listing on the New York
Stock Exchange of the Motorola shares issuable to the C-Port stockholders in
the merger, subject only to official notice of issuance, is a condition to the
obligations of Motorola, CP Acquisition Corp. and C-Port to complete the
merger. See "--Conditions to the Merger" on page 45.

   No Solicitation. The merger agreement provides that C-Port will not,
directly or indirectly, and will not authorize or permit any of its
representatives or affiliates to encourage, solicit, initiate or facilitate any
acquisition proposal, enter into any agreement with respect to any acquisition
proposal, participate in any discussion or negotiation regarding any
acquisition proposal or furnish information to any person to facilitate any
inquiries or the making of any proposal that could constitute an acquisition
proposal. C-Port will as promptly as practicable advise Motorola of its receipt
of and of the terms of any acquisition proposal and inquiries with respect to
any acquisition proposal.

   An acquisition proposal means any offer or proposal concerning any:

  . merger, consolidation, business combination or similar transaction
    involving C-Port;

  . sale, lease or other disposition directly or indirectly by merger,
    consolidation, business combination, share exchange, joint venture or
    otherwise of assets of C-Port representing 10% or more of the assets of
    C-Port;

  . issuance, sale or other disposition of securities representing 10% or
    more of the voting power of C-Port; or

    the Securities Exchange Act of 1934) shall acquire beneficial ownership
    (as defined in Rule 13d-3 under the Securities Exchange Act of 1934) of
    10% of more of the outstanding voting stock of C-Port.

   Proxy Statement and Registration Statement. C-Port has agreed to prepare,
file and mail a proxy statement relating to the C-Port special meeting of
stockholders which will include the recommendation of the C-Port board of
directors to its stockholders to vote in favor of the merger agreement and the
merger.

   Stockholders' Meeting. C-Port has agreed to call and hold a meeting of its
stockholders relating to the required stockholder approval of the merger as
promptly as possible and to use its best efforts to hold such meeting as soon
as practicable after the Motorola registration statement of which this proxy
statement/prospectus is a part becomes effective.

   Appropriate Action; Consents and Filings. The merger agreement provides that
C-Port and Motorola will use their reasonable best efforts to:

  . take, or cause to be taken, all appropriate action and do, or cause to be
    done, all things necessary, proper or advisable under applicable law or
    otherwise to complete the transactions contemplated by the merger
    agreement as promptly as practicable;

  . obtain any consents, licenses, approvals or other items from any
    governmental entities that are required to be obtained, or to avoid any
    action or proceeding by any governmental entity, in connection with the
    merger agreement and the completion of the transactions contemplated by
    the merger agreement; and

  . make all necessary filings with respect to the merger agreement and the
    merger required under applicable law.

   Regardless of the agreements described in the preceding sentence, Motorola
is not obligated under the merger agreement to agree to the imposition of
conditions, the requirement of divestiture, or the requirement of expenditure
of money by Motorola to a third party in exchange for any such consent that, in
any case, would be materially adverse to Motorola, C-Port and their
subsidiaries, taken as a whole.

   Plan of Reorganization. Each of Motorola, CP Acquisition Corp. and C-Port
have agreed to use its reasonable best efforts to cause the merger to qualify,
and will not knowingly take any action or cause any action to be taken that
could reasonably be expected to prevent the merger from qualifying, as a
reorganization under the provisions of Section 368(a) of the Code. After the
effective time of the merger, Motorola, the surviving corporation in the merger
and their affiliates will not knowingly take any action or knowingly cause any
action to be taken that could reasonably be expected to cause the merger to
fail to qualify as a reorganization under Section 368(a) of the Code.

   Conduct of Business of Motorola Pending the Merger. Motorola has agreed,
with certain exceptions, that it will not (unless required by applicable laws
or New York Stock Exchange regulations), and will not permit CP Acquisition
Corp. (unless required by applicable laws or New York Stock Exchange
regulations) to, between the date of the merger agreement and the effective
time of the merger, directly or indirectly take any action, without the consent
of C-Port, that is intended or could reasonably be expected to result in any of
the conditions to the merger not being satisfied.

Conditions to the Merger

   Neither Motorola nor C-Port will be obligated to complete the merger unless
certain conditions are satisfied or are waived, including the following:

  . the registration statement on Form S-4, of which this proxy

  . approval of the merger agreement and the merger by the requisite vote of
    the C-Port stockholders;

  . receipt of certain consents, approvals and authorizations of governmental

    case, without the imposition of conditions, the requirement of
    divestiture or the expenditure of money by Motorola or C-Port to a third
    party in exchange for any such consent that, in any such case, would be
    materially adverse to Motorola and its subsidiaries or C-Port) unless the
    failure to obtain such consents would not, individually or in the
    aggregate, reasonably be expected to have a material adverse effect on C-
    Port or on Motorola after the merger;

  . approval of Motorola common stock issuable to C-Port stockholders in the
    merger for listing on the New York Stock Exchange, subject to official
    notice of issuance;

    Hollingsworth, Kurt Hoff, Clint Ramsay, and John Burnham;

  . no law, judgment, regulation, injunction, arbitration award, decree or
    order may be in effect for either party that prevents or prohibits the
    merger;

  . the waiting period under applicable federal antitrust laws, and any
    extension, must have expired or been terminated; and

  . each of Motorola and C-Port must have received an opinion of its tax
    counsel, Winston & Strawn and Hale and Dorr LLP, respectively, stating
    that for United States federal income tax purposes the merger will
    qualify as a reorganization within the meaning of Section 368(a) of the
    Internal Revenue Code.

    all material respects on the closing date of the merger;

    obligations and covenants required to be performed prior to the effective
    time of the merger and must have delivered an officer's certificate to
    such effect; and

  . Motorola must have received "cold comfort" letters from
    PricewaterhouseCoopers LLP dated the date on which the Registration
    Statement on Form S-4, of which this proxy statement/prospectus forms a
    part, becomes effective and a date at least two days prior to the
    effective date of the merger.

                                       45

Additional Conditions to the Obligations of C-Port

   C-Port is not obligated to complete the merger unless the following
additional conditions are satisfied or waived by C-Port:

  . the representations and warranties of Motorola must remain true and
    correct in all material respects on the closing date of the merger;

    Port shall have been registered under the Securities Act of 1933, as
    amended.

   Each of the foregoing conditions is waivable by Motorola or C-Port, as the
case may be, to the extent legally permissible.

Termination

   The merger agreement may be terminated at any time prior to the effective
time of the merger, whether before or after approval and adoption of the merger
agreement and the merger by the C-Port stockholders:

  . by mutual consent of Motorola and C-Port;

  . by either Motorola or C-Port if:

    . the company seeking to terminate under this provision is not then in
      material breach of any representation, warranty, covenant or other
      agreement contained in the merger agreement;

    . there has been a breach by the other company of any of its
      representations, warranties, covenants or agreements contained in the
      merger agreement or any of its representations and warranties becomes
      untrue;

    . such breach or condition would prevent the satisfaction of the
      closing conditions described under "--Representations and Warranties"
      on page 42; and

    . such breach or condition has not been promptly cured within 30 days
      following receipt by such company of written notice of its breach;

  . by either Motorola or C-Port if any decree, permanent injunction,
    judgment, order or other action by any court of competent jurisdiction,
    any arbitrator or any governmental entity preventing or prohibiting the
    completion of the merger shall have become final and nonappealable, so
    long as the party seeking termination is not in breach of its obligation
    to use its reasonable best efforts to take appropriate action, obtain the
    necessary consents and make all necessary filings in connection with the
    merger agreement and the merger; or

  . by either Motorola or C-Port if the merger has not been completed before
    May 31, 2000 (subject to extension by either party to June 30, 2000 so
    long as the party requesting extension is not then in material breach of
    any representation, warranty or covenant in the merger agreement).

   Effect of Termination. The merger agreement provides that no termination of
the merger agreement shall release any party of any liabilities under the
merger agreement for any breaches of the merger agreement prior to the
termination or intentional misrepresentations made in the merger agreement.

Fees and Expenses

   Whether or not the merger is completed, each of Motorola and CP Acquisition
Corp. will pay its own fees, expenses and disbursements incurred by it in
connection with the negotiation and preparation of the merger agreement and its
performance and compliance thereunder. If the merger is completed, the C-Port
stockholders

                                       46
<PAGE>

shall pay, from the escrow fund, the fees, expenses and disbursements of C-Port
and the C-Port stockholders, in excess of $2.5 million in the aggregate for all
such fees, expenses and disbursements, incurred by them in connection with the
negotiation and preparation of the merger agreement and their performance and
compliance thereunder.

   If the merger is not completed, C-Port shall pay all of the fees, expenses
and disbursements incurred by C-Port and the C-Port stockholders in connection
with the negotiation and preparation of the merger agreement and their
performance and compliance thereunder.

Amendment

   The merger agreement may be amended, either before or after the stockholders
of C-Port vote on the merger, by an instrument in writing signed by the
parties. However, after the stockholders of C-Port approve the merger, any
later amendment which by law requires stockholder approval may only be made
with such approval.

Waiver

   The merger agreement provides that, at any time prior to the effective time
of the merger, Motorola, CP Acquisition Corp. or C-Port may:

  . extend the time for the performance of any of the obligations or other
    acts of the other parties to the merger agreement;

  . waive any inaccuracies in the representations and warranties of the other
    party contained in the merger agreement or in any document delivered
    pursuant to the merger agreement;

  . waive compliance by another party with any of the agreements or
    conditions contained in the merger agreement; and

  . any such extension or waiver will be valid only if it is set forth in a
    written instrument signed by the party or parties to be bound thereby.
    Such extension or waiver or failure to insist on strict compliance with
    an obligation, agreement or condition will not operate as a waiver of, or
    bar any claim with respect to, any subsequent or other failure.

Voting Agreement

   On February 17, 2000, in connection with the merger agreement, Laurence G.
Walker, Bruce Sachs, Thomas Brightman, Robi Soni, Charles River Partnership
VIII, A Limited Partnership, Charles River VIII-A LLC, Bessemer Venture
Investors IV LP, Bessemer Venture Investors L.P., BVP IV Special Situations
L.P., Bessec Ventures IV L.P., Benchmark Capital Partners II, L.P., Robert H.
Buescher, the other stockholders of C-Port named therein, C-Port and Motorola
entered into a voting agreement pursuant to which the C-Port stockholders
parties to the voting agreement agreed to vote all of the C-Port shares that
they will beneficially own at the record date of the special meeting of C-Port
stockholders for the approval and adoption of the merger agreement, the merger
and the other transactions contemplated by the merger agreement, including the
appointment of Laurence G. Walker as stockholder representative under the
merger agreement. As of the date of the voting agreement, the stockholders
represented that they collectively held approximately 1,878,000 C-Port common
shares, 4,832,850 C-Port Series A preferred shares, 5,192,962 C-Port Series B
preferred shares and 3,327,551 Series C preferred shares, representing
approximately 55.7% of the C-Port common and preferred stock, voting together
as a single class, and approximately 69.8% of the C-Port Series A preferred
stock, Series B preferred stock and Series C voting stock, voting together as a
single class.

   In the voting agreement, a copy of which is attached as Appendix C to this
proxy statement/prospectus, the stockholders agreed to cooperate fully with
Motorola and C-Port in connection with the merger agreement and the
transactions contemplated by the merger agreement. The stockholders also agreed
to not initiate, solicit

                                       47
<PAGE>

or facilitate any discussions, inquiries or proposals with any third party that
constitute or may reasonably be expected to lead to an acquisition of C-Port.

   The voting agreement also provides that each stockholder that is a party to
it will not, and will not agree to, contract to or sell or otherwise transfer
or dispose of any of his or its C-Port shares, or any interest in those shares,
or convertible securities, or any shares obtained upon the exercise of
convertible securities, or any other securities convertible into or
exchangeable for C-Port common stock or any voting rights with respect thereto,
other than:

  . pursuant to the merger; or

  . with the prior written consent of Motorola.

   The voting agreement is intended to bind each stockholder that is a party to
it only with respect to the specific matters set forth in the voting agreement,
and shall not prohibit such stockholders from acting in accordance with their
fiduciary duties as officers and/or directors of C-Port.

   The voting agreement is terminable at the option of any party at any time
after the earlier of:

  . the termination of the merger agreement; and

  . the day following the effective time of the merger.

Appointment of Stockholder Representative

   Pursuant to the terms of the merger agreement, each holder of shares of C-
Port common stock who votes in favor of the merger or who receives or accepts
shares of Motorola common stock as the merger consideration will be deemed to
have appointed Laurence G. Walker as stockholder representative and will be
deemed to have consented to the performance by the stockholder representative
of all rights and obligations conferred on the stockholder representative under
the merger agreement and the escrow agreement. The stockholder representative
is not liable to the C-Port stockholders with respect to any action or inaction
taken or suffered by him, in the absence of willful misconduct or gross
negligence on the part of the stockholder representative. For more information
on the escrow agreement, see "--Indemnification of Motorola; Escrow Agreement"
on page 48.

Indemnification of Motorola; Escrow Agreement

   The merger agreement provides that 290,786 shares of Motorola common stock
to be issued in connection with the merger will be deposited in escrow with an
escrow agent as soon as practicable after the closing date of the merger. If
the merger occurs after May 15, 2000, the record date for the three-for-one
stock split of Motorola's common stock approved by the Motorola board of
directors on February 29, 2000, the number of shares to be deposited in escrow
will increase to 872,358 in order to reflect the stock split. This represents
10% of the shares of Motorola common stock the stockholders would otherwise be
entitled to receive in the merger. The escrow account is the only source
available to compensate Motorola for the indemnification obligations of each C-
Port stockholder under the merger agreement, except that Motorola may elect not
to have recourse to the escrow account for any claim of fraud. Shares of
Motorola stock subject to issuance upon the exercise of stock options issued
under C-Port's 1997 stock incentive plan will not be included in the escrow
account.

   The C-Port stockholders have agreed to indemnify Motorola and its directors,
officers, employees, agents and advisors, from and against any and all damages
and liabilities (including reasonable legal fees) arising out of:

  . any inaccuracy in any representation or warranty made by C-Port in the
    merger agreement or in the disclosure schedule to the merger agreement;

  . the failure of C-Port to perform any of the covenants or agreements given
    or made by it in the merger agreement;

                                       48
<PAGE>

  . certain fees, expenses and disbursements incurred by C-Port in connection
    with the merger in excess of $2.5 million;

  . any governmental action, order or directive, administrative proceeding or
    ruling;

  . personal or bodily injuries or damage to any premises;

  . any violation or alleged violation of environmental laws existing prior
    to the effective time of the merger; and

  . certain other matters described in the disclosure schedule to the merger
    agreement.

With respect to claims for indemnification, Motorola may not seek
indemnification from the C-Port stockholders until the aggregate amount of all
damages for which Motorola is seeking indemnification, exclusive of legal fees
incurred in pursuing Motorola's claim and certain other amounts described in
the merger agreement, is at least $100,000.

   The escrow fund will terminate on the first anniversary of the closing date
of the merger. On the first anniversary, all shares of Motorola common stock
remaining in the escrow fund will be released, except for shares as to which
Motorola has made a claim before the first anniversary and which claim is
unresolved. If Motorola has made a claim for indemnification prior to such
date, the escrow agent will retain in escrow shares and dividends that have a
value of 125% of the claimed amount. Escrowed shares that are released from the
escrow fund will be promptly delivered by the escrow agent to the C-Port
stockholders in accordance with each stockholder's percentage of the escrow
fund.

   The merger agreement provides that Laurence G. Walker is appointed as
representative of, for and on behalf of C-Port stockholders to take all actions
necessary or appropriate in his judgment for the accomplishment of the terms of
the merger agreement. Notices of communications to or from the stockholders'
representative will constitute notice to or from each of the C-Port
stockholders. If the stockholders' representative dies or is otherwise no
longer able or willing to serve as the stockholder representative, a new
stockholder representative will be chosen by C-Port stockholders holding a
majority of Motorola common stock issued in connection with the merger.

   The stockholder representative will not be liable for any act done or
omitted in the absence of willful misconduct or gross negligence pursuant to
the advice of counsel.

   The stockholder representative has full power and authority to represent the
C-Port stockholders and their successors with respect to all matters under the
escrow agreement. All actions taken by the stockholder representative under the
escrow agreement will be binding upon the C-Port stockholders and their
successors. The escrow agent may rely on the stockholder representative as your
exclusive agent under the escrow agreement and will not incur any liability to
any party in so relying.

   Any dividends distributed on the escrowed shares are to be held in the
escrow fund. Additionally, the stockholder representative has the right to
direct the escrow agent to exercise the voting rights of the escrow shares in
his sole discretion.

   The value of the escrowed shares is the average of the last reported sale
price per share of Motorola common stock over the five consecutive trading days
preceding the date of distribution of the escrow shares. Motorola will pay the
fees and expenses of the escrow agent.

                     DESCRIPTION OF MOTOROLA CAPITAL STOCK

   The following description of certain terms of the capital stock of Motorola
does not purport to be complete and is qualified in its entirety by reference
to the Motorola charter. For more information as to how you can obtain the
Motorola charter, see "Where You Can Find More Information" on page 67.

Motorola Common Stock

   The Motorola charter authorizes Motorola to issue up to 1.4 billion shares
of Motorola common stock, par value $3.00 per share. On May 1, 2000, the
Motorola stockholders will be asked to consider and approve an amendment to
Motorola's charter increasing the number of authorized shares of Motorola
common stock from 1.4 billion shares to 4.2 billion shares in order to provide
for, among other things, shares of Motorola common stock to be issued on June
1, 2000 to Motorola common stockholders of record as of May 15, 2000 as a
dividend in connection with a three-for-one split of Motorola's common stock
approved by the Motorola board of directors on February 29, 2000. Each Motorola
share is entitled to one vote, in person or by proxy, at any and all meetings
of the Motorola stockholders on all propositions before such meetings and on
all elections of directors of Motorola. The Motorola charter does not provide
for cumulative voting in the election of directors. Subject to any preferential
rights of any outstanding series of Motorola preferred stock created by the
Motorola board of directors from time to time, the holders of Motorola common
stock are entitled to dividends only if, when and as the dividends are declared
by the Motorola board of directors and as may be permitted by law, and, upon
liquidation, will be entitled to receive pro rata all assets of Motorola
available for distribution to such holders. As of March 23, 2000, approximately
717,314,579 Motorola shares were issued and outstanding, held by approximately
49,618 holders of record. For a description of voting requirements and change
of control restrictions, see "--Motorola Rights Plan" on pages 51-52 and
"Comparison of Certain Rights of Stockholders of Motorola and C-Port" on pages
53-58.

Motorola Preferred Stock

   Motorola is also authorized to issue up to 500,000 shares of preferred
stock, par value $100 per share, from time to time in one or more series and
with such designation for each such series as determined by the Motorola board
of directors. The Motorola board of directors may, without further action by
the Motorola stockholders, issue a series of Motorola preferred stock and state
and fix the rights and preferences of those shares, including:

  . the voting powers, if any, of the holders of stock of such series;

  . the rate per annum and the times at and conditions upon which the holders
    of stock of such series will be entitled to receive dividends, and
    whether such dividends will be cumulative or noncumulative and, if
    cumulative, the terms upon which such dividends will be cumulative;

  . the price or prices and the time or times at and the manner in which the
    stock of such series will be redeemable;

  . the right to which the holders of the shares of stock of such series
    shall be entitled upon any voluntary or involuntary liquidation,
    dissolution or winding-up of Motorola;

  . the terms, if any, upon which shares of stock of such series shall be
    convertible into, or exchangeable for, shares of any stock of any other
    class or classes or of any other series of the same or any other class or
    classes, including the price or prices or the rate or rates of conversion
    or exchange and the terms of adjustment, if any; and

  . any other designations, preferences, and relative, participating,
    optional or other special rights, and qualifications, limitations or
    restrictions thereof so far as they are not inconsistent with the
    provisions of the Motorola certificate of incorporation, as amended, and
    to the full extent now or hereafter permitted by the laws of Delaware.

                                       50
<PAGE>

   On November 5, 1998, the Motorola board of directors designated a series of
Motorola preferred stock, Junior Participating Preferred Stock, Series B (the
"Motorola Series B Preferred Stock") and authorized 250,000 shares for issuance
in connection with the adoption of the Motorola rights plan. As of March 23,
2000, no shares of Motorola preferred stock of any series were outstanding.

Motorola Rights Plan

   On November 5, 1998, the Motorola board of directors authorized the issuance
of one preferred share purchase right (a "Right") for each outstanding Motorola
share, pursuant to a Rights Agreement between Motorola and Harris Trust and
Savings Bank, as Rights Agent. Each Right entitles the registered holder to
purchase from Motorola one ten-thousandth of a share of Motorola Series B
Preferred Stock at an exercise price of $200 per one ten-thousandth of a share
of Motorola Series B Preferred Stock, subject to adjustment. The Rights become
exercisable on the earlier of:

  . the tenth day after a public announcement that a person or group of
    affiliated or associated persons has acquired or obtained the right to
    acquire 10% or more of the outstanding Motorola shares (thereby becoming
    an "Acquiring Person"); and

  . the tenth business day after the commencement or public disclosure of an
    intention to commence a tender offer or exchange offer by a person other
    than an exempt person if, upon completion of the offer, such person could
    become an Acquiring Person.

   A majority of the Motorola board of directors may elect to defer the date on
which the Rights become exercisable. The Rights expire on November 20, 2008
unless earlier redeemed or exchanged by Motorola as described below.

   If a person or group becomes an Acquiring Person, each holder of a Right
(except those held by the Acquiring Person and its affiliates and associates)
will have the right to purchase, upon exercise, Motorola shares (or, in certain
circumstances, shares of Motorola Series B Preferred Stock, common stock
equivalents or cash) having a value equal to two times the exercise price of
the Right. In addition, in the event that, at the time or after a person
becomes an Acquiring Person, Motorola is involved in a merger or other business
combination in which (1) Motorola is not the surviving corporation, (2)
Motorola common stock is changed or exchanged, or (3) 50% or more of Motorola's
consolidated assets or earning power are sold, then each Right (other than
Rights that are or were owned by the Acquiring Person and certain related
persons and transferees, which will thereafter be void) will thereafter be
exercisable for a number of shares of common stock of the acquiring company
having a market value of two times the exercise price of the Right. In
addition, at any time after any person or group becomes an Acquiring Person and
before any person acquires 50% or more of the outstanding Motorola shares and
before a business combination occurs, the Motorola board of directors may
exchange the Rights (other than Rights owned by the Acquiring Person which will
have become void), in whole or in part, at an exchange ratio of one Motorola
share, or one ten-thousandth of a share of Motorola Series B Preferred Stock
(or a common stock equivalent), per Right (subject to adjustment).

   The Motorola board of directors may redeem all, but not less than all,
Rights at a redemption price of $.01 per Right at any time prior to the time
that a person or a group has become an Acquiring Person. Immediately upon
redemption, the right to exercise will terminate, and the only right of holders
will be to receive the redemption price. As long as the Rights are redeemable,
the terms of the Rights may be amended by the Motorola board of directors in
its discretion without the consent of the Rights holders. After that time, no
amendment may adversely affect the interests of the Rights holder (other than
the Acquiring Person).

   The Rights will not prevent a takeover of Motorola. The Rights, however, may
have certain antitakeover effects. The Rights may cause substantial dilution to
a person or group that attempts to acquire Motorola on terms not approved by
the Motorola board of directors or make the acquisition of Motorola
substantially more costly, unless the Motorola board of directors redeems the
Rights prior to the person becoming an Acquiring

                                       51
<PAGE>

Person. The Rights should not interfere with any merger or other business
combination approved by the Motorola board of directors because of the board's
ability to redeem the Rights or amend the Motorola rights plan. A description
of the Motorola rights plan specifying the terms of the Rights and the
Motorola Series B Preferred Stock has been included in reports filed by
Motorola under the Securities Exchange Act of 1934, as amended. See "Where You
Can Find More Information" on page 67. This summary description is qualified
in its entirety by reference to the Motorola rights plan.

   Each share of Motorola common stock issued in the merger will have a
corresponding Right attached to it.

Transfer Agent; Registrar and Exchange Agent

   Harris Trust and Savings Bank is the transfer agent and registrar for the
Motorola common stock.

             COMPARISON OF CERTAIN RIGHTS OF COMMON STOCKHOLDERS OF
                      MOTOROLA AND STOCKHOLDERS OF C-PORT

   The rights of Motorola and C-Port stockholders are currently governed by the
Delaware General Corporation Law, and the respective charter and by-laws of
Motorola and C-Port. Upon completion of the merger, the rights of C-Port
stockholders who become stockholders of Motorola in the merger will be governed
by the Delaware General Corporation Law, Motorola's charter and Motorola's by-
laws.

   The following description summarizes the material differences that may
affect the rights of common stockholders of Motorola and stockholders of C-Port
but does not purport to be a complete statement of all those differences, or a
complete description of the specific provisions referred to in this summary.
The identification of specific differences is not intended to indicate that
other equally or more significant differences do not exist. You should read
carefully the relevant provisions of the Delaware General Corporation Law,
Motorola's charter, Motorola's by-laws, C-Port's charter and C-Port's by-laws.

Capitalization

   Motorola. Motorola's authorized capital stock is described above under
"Description of Motorola Capital Stock" on page 50.

   C-Port. The authorized capital stock of C-Port consists of 30,000,000 shares
of common stock, par value $0.001 per share, and 19,716,667 shares of preferred
stock, par value $0.001 per share, of which 5,366,667 shares are designated
Series A convertible redeemable preferred stock, 5,900,000 shares are
designated Series B convertible redeemable preferred stock, 8,450,000 shares
are designated Series C convertible redeemable preferred stock. As of March 23,
2000, 8,198,182 shares of C-Port common stock are issued and outstanding,
5,266,266 shares of series A preferred stock are issued and outstanding,
5,409,736 shares of Series B preferred stock are issued and outstanding and
8,449,944 shares of Series C preferred stock are issued and outstanding and
226,031 shares of Series B preferred stock are issuable upon exercise of rights
under warrant agreements.

Voting Stock

   Motorola. The outstanding voting securities of Motorola are the shares of
Motorola common stock.

   C-Port. Each holder of C-Port common stock is entitled to one vote for each
share held at all meetings of stockholders and written actions in lieu of
meetings. C-Port's charter does not provide for cumulative voting. Each holder
of C-Port preferred stock is entitled to the number of votes equal to the
largest number of whole shares of common stock into which the shares of
preferred stock held are then convertible. Except as provided by law, and in
certain situations set forth in C-Port's charter, holders of preferred stock
vote together with the holders of common stock as a single class.

Number of Directors

   Motorola. The Motorola by-laws provide that the Motorola board of directors
shall consist of 16 directors or such other number that the Motorola board of
directors may fix. The Motorola board of directors currently consists of 15
directors.

   C-Port. The C-Port by-laws provide that the C-Port board of directors or
stockholders have the right to fix the number of directors by resolution, but
there must be at least one director. The C-Port board currently consists of

    its stockholders;

                                       55
<PAGE>

   Motorola's charter provides a right to indemnification to directors and
officers of Motorola to the fullest extent permitted by the Delaware General
Corporation Law.

   In addition, Motorola must indemnify any present or former director or
officer of the corporation who is or was serving at the request of the
corporation as a director, officer, employee or agent of another corporation
who has been successful on the merits or otherwise in the defense of any claim
or proceeding for expenses (including attorneys' fees) actually and reasonably
incurred. Motorola will indemnify in connection with a proceeding initiated by
such indemnitee only if such proceeding was authorized by Motorola's board of
directors.

   C-Port. C-Port's charter provides that a director will not be personally
liable to C-Port or its stockholders for monetary damages for breach of
fiduciary duty as a director, except, if required by law. C-Port's charter
further provides that C-Port will indemnify each person who was or is a party
or is threatened to be made a party to any suit by reason of the fact that he
is or was a director or officer of the Company or is or was serving at the
request of the Company as a director, officer or trustee of another Corporation
against all expenses (including attorneys' fees), judgements, and amounts paid
in settlements. These expenses incurred by the director or officer will be
indemnified only if he or she acted in good faith and in a manner he or she
reasonably believed to be in the best interests of the Company, and with
respect to any criminal action, had no reasonable cause to believe his or her
conduct was unlawful. C-Port will not indemnify in connection with a proceeding
initiated by any officer or director unless initiation was approved by the C-
Port board of directors. C-Port will indemnify any officer or director who was
or is a party to any suit by or in the right of the Company only if he or she
acted in good faith and in a manner he reasonably believed to be in the best
interests of the Company, except no indemnification will be made if the person
is held to be liable to the Company, unless the Delaware court of chancery
determines that despite such liability, he is fairly and reasonably entitled to
indemnity. C-Port's charter provides that if an indemnitee is successful, on
the merits or otherwise, of a suit, he shall be indemnified against all
expenses (including attorneys' fees) actually and reasonably incurred by him or
on his behalf and sets forth the conditions under which the officer or director
shall be considered to have been wholly successful.

   C-Port is entitled to participate at its own expense and to assume the
defense with legal counsel reasonably acceptable to the applicable officer or
director.

Dividends

   Motorola. Motorola's charter provides that the board of directors may, by
resolution, state the conditions upon which the holders of preferred stock
shall be entitled to receive dividends. The common stockholders shall be
entitled to dividends only if the board of directors declares dividends and as
may be permitted by law.

   C-Port. C-Port's charter provides that dividends may be declared and paid on
the common stock from funds lawfully available therefor as and when determined
by the board of directors, out of assets legally available therefor, subject to
any preferential dividend rights of any then outstanding preferred stock. The
holders of the preferred stock are entitled, when, as and if declared by the
board of directors of C-Port, to dividends out of the corporation's assets
legally available therefor at the annual rate of 9.5% of $0.375 on the Series A
Preferred Stock; the prime rate plus 1% of $1.13 on the Series B preferred
stock; and the prime rate plus 1% of $2.73 on the Series C preferred stock.
Dividends may be declared and paid upon the common stock in any fiscal year
only if dividends have been paid to or declared and set apart for payment to
all shares of preferred stock at such annual rate for such fiscal year. After
the holders of preferred stock have received their dividend preference as set
forth above, the holders of preferred stock and common stock are entitled,
when, as and if declared by the board of directors, to dividends out of C-
Port's assets legally available therefor; provided, that no such dividends may
be declared or paid on any shares of common stock or preferred stock unless at
the same time an equivalent dividend is declared and paid on all outstanding
shares of common

                                       56
<PAGE>

stock and preferred stock; and provided further that the dividend on each
series of preferred stock is payable at the same rate per share as would be
payable on the shares of common stock or other securities into which such
series of preferred stock is convertible immediately prior to the record date
for such dividend. The right to dividends on shares of the preferred stock is
cumulative, such that (subject to restrictions set forth in C-Port's charter),
if dividends in respect of any previous or current dividend period, have not
been paid or declared and a sum sufficient for the payment thereof set apart,
the deficiency must first be paid before any dividend or other distribution may
be paid on or declared and set apart for the Series A preferred stock. C-Port
may not declare or pay any dividends or other distributions on shares of common
stock unless the holders of the preferred stock then outstanding simultaneously
receives an equivalent dividend on each outstanding share of preferred stock in
an amount at least equal to the product of (i) the per share amount, if any, of
the dividends or other distributions to be declared, paid or set aside for the
common stock, multiplied by (ii) the number of whole shares of common stock
into which such share of preferred stock is then convertible.

Liquidation

   Motorola. Motorola's charter provides that the board of directors may, by
resolution, state the right to which the preferred stockholders shall be
entitled upon any voluntary or involuntary liquidation, dissolution or winding
up of the corporation. Holders of Motorola common stock have no preferential
rights with respect to liquidation.

   C-Port. C-Port's charter provides that in the event of any voluntary or
involuntary liquidation, dissolution or winding up of C-Port, the holders of
shares of C-Port preferred stock then outstanding are entitled to be paid out
of C-Port's assets available for distribution to its stockholders before any
payment may be made to the holders of C-Port common stock by reason of their
ownership thereof,

  . an amount equal to the Series A Base Amount (as defined in C-Port's
    charter) for each share of Series A preferred stock then held by them;

  . an amount equal to the Series B Base Amount (as defined in C-Port's
    charter) for each share of Series B preferred stock then held by them;
    and

  . an amount equal to the Series C Base Amount (as defined in C-Port's
    charter) for each share of Series C preferred stock then held by them,

in each case subject to appropriate adjustment in the event of any stock
dividend, stock split, combination or other similar recapitalization affecting
such preferred shares, plus any dividends declared or accrued but unpaid on
such preferred shares. In addition, after payment of the Series A Base Amount,
Series B Base Amount and Series C Base Amount, the holders of preferred stock
are entitled to share ratably with the holders of common stock in the remaining
net assets of C-Port, until each of the holders of preferred stock shall
received an amount per share equal to three times their original purchase price
per share. If upon any liquidation, dissolution or winding up of C-Port the
remaining assets of C-Port available for distribution to its stockholders are
insufficient to pay the holders of shares of C-Port preferred stock the full
amount to which they are entitled, the holders of shares of C-Port preferred
stock will share ratably in any distribution of the remaining assets and funds
of C-Port in proportion to the respective amounts which would otherwise be
payable in respect of the shares held by them upon such distribution if all
amounts payable on or with respect to such shares were paid in full.

Conversion

   Motorola. Motorola's charter provides that the board of directors may, by
resolution, state the terms upon which shares of preferred stock shall be
convertible into, or exchangeable for, shares of stock of any other class or
classes of any other series, including the price, the rate of conversion and
the terms of adjustment. Holders of Motorola common stock have no rights to
convert their shares into any other securities.

                                       57
<PAGE>

   C-Port. Holders of C-Port common stock have no rights to convert their
shares into any other securities. Subject to certain terms, conditions,
limitations and adjustments set forth in the C-Port's charter, holders of each
series of C-Port preferred stock have the right at their option to convert any
such shares, without the payment of additional consideration, into the number
of fully paid and nonassessable shares of C-Port common stock as is determined
by the formulae set forth in the charter. Based on the formula contained in C-
Port's charter, each share of C-Port preferred stock is currently convertible
into one share of C-Port common stock.

   No fractional shares of common stock or scrip may be issued upon conversion
of shares of preferred stock. In lieu of any fractional shares to which the
holder would otherwise be entitled, C-Port will pay cash equal to the fair
market value of such fractional shares.

   Option Grants and Restricted Stock Awards in Last Fiscal Year. On January
27, 2000, C-Port granted an option to Mr. Burnham to purchase 60,000 shares of
C-Port common stock at a per share exercise price of $2.46. These options vest
25% on the first anniversary of his employment and monthly thereafter over the
next three years. On February 17, 2000 C-Port's board of directors approved a
resolution that provides for 50% of all unvested shares of C-Port common stock
subject to outstanding options to immediately vest at the effective time of the
merger, with the remaining 50% vesting ratably on a monthly basis over the 12
month period following the effective date of the merger. This acceleration of
unvested shares with regard to option holders who may be disqualified
individuals within the meaning of Section 280G of the Internal Revenue Code is
subject to stockholder approval. See "The Merger--Treatment of C-Port Stock
Options and Restricted Stock" on page 30.

   In 1999, C-Port granted restricted stock awards to the following
individuals:

    share.

   The restricted awards granted to Messrs. Gavin, Hoff, Ramsay and
Hollingsworth each vest 25% on the first anniversary of their employment with
the remaining 75% vesting ratably on a monthly basis over a three year period
thereafter. Mr. Morris' restricted stock award is fully vested. Each of their
restricted stock agreements also provides that, in the event of a transaction
such as the merger, each of them is entitled to acceleration of one-half of the
unvested portion of their restricted stock and vesting of the remaining one-
half over the 12 month period following such transaction.

   Each officer of C-Port has a provision in his or her respective restricted
stock agreement providing that if, within 365 days after the effective date of
the merger, such officer ceases to serve C-Port in his or her current capacity,

reason, then the remaining one-half of such shares of restricted stock shall
immediately accelerate and vest in full. Under the terms of the merger
agreement, the directors and officers will receive the same consideration in
connection with the merger as other C-Port stockholders. The merger agreement
provides that each such share of C-Port common stock that is unvested at the
effective time of the merger shall be converted into 0.1022485 of a share of
Motorola common stock, or 0.3067455 of a share of Motorola common stock if the
merger occurs after May 15, 2000, but remains subject to the vesting,

   The following table sets forth information regarding the beneficial
ownership of C-Port's common stock as of March 23, 2000, by the directors,
executive officers and stockholders holding more than 5% of the stock of C-
Port. To the knowledge of C-Port and unless otherwise indicated, each person
named in the table has sole voting power and investment power, or shares such
power with his or her spouse, with respect to all shares of capital stock
listed as owned by such person. The address of each C-Port officer and director
is c/o C-Port Corporation, One High Street, North Andover, Massachusetts 01845.

   The number of shares beneficially owned by each stockholder is determined

indicative of beneficial ownership for any other purpose. Under these rules,
beneficial ownership includes any shares as to which the individual has sole or
shared voting power or investment power and any shares as to which the
individual has the right to acquire beneficial ownership within 60 days after
March 23, 2000 through the exercise of any stock option, warrant or other
right. The inclusion in the following table of those shares, however, does not

beneficial owner of those shares.

               SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

   This proxy statement/prospectus includes "forward-looking statements" within
the meaning of Section 27A of the Securities Act and Section 21E of the
Securities Exchange Act of 1934, as amended. Such statements are identified by
the use of forward-looking words or phrases including, but not limited to,
"intended," "will be positioned," "expects," "expected," "anticipates," and
"anticipated." These forward-looking statements are based on current
expectations of Motorola or C-Port, as the case may be. All statements other
than statements of historical facts included in this proxy
statement/prospectus, including those regarding the financial position, results
of operations, cash flows, business strategy, projected costs, growth
opportunities for existing products, benefits from new technology and plans and
objectives of management for future operations of Motorola or C-Port, as the
case may be, are forward-looking statements. Although Motorola or C-Port
believes that the expectations of Motorola or C-Port, as the case may be,
reflected in such forward-looking statements are reasonable, there can be no
assurance that such expectations will prove to have been correct. Because
forward-looking statements involve risks and uncertainties, the actual results
of Motorola and C-Port, as the case may be, could differ materially. Important
factors that could cause actual results to differ materially from the
expectations of Motorola or C-Port, as the case may be ("Cautionary
Statements"), are disclosed under "Risk Factors Relating to the Merger,"
"Reasons for the Merger," and elsewhere in this proxy statement/prospectus and
in Motorola's SEC filings listed on page 67. These forward-looking statements
represent the judgment of Motorola or C-Port, as the case may be, as of the
date of this proxy statement/prospectus. All subsequent written and oral
forward-looking statements attributable to Motorola or C-Port or persons acting
on behalf of Motorola or C-Port are expressly qualified in their entirety by
the Cautionary Statements. Motorola and C-Port disclaim, however, any intent or
obligation to update their respective forward-looking statements.

"Agreement"), by and among Motorola, Inc., a Delaware corporation ("Parent"),
CP Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of
Parent ("Merger Sub"), and C-Port Corporation, a Delaware corporation (the
"Company").

   WHEREAS, the respective Boards of Directors of Parent, Merger Sub and the
Company have approved and declared advisable the merger of Merger Sub with and
into the Company (the "Merger") upon the terms and subject to the conditions of
this Agreement and in accordance with the General Corporation Law of the State
of Delaware (the "DGCL");

   WHEREAS, the respective Boards of Directors of Parent and the Company have
determined that the Merger is in furtherance of and consistent with their
respective business strategies and is in the best interest of their respective
stockholders, and Parent has approved this Agreement and the Merger as the sole
stockholder of Merger Sub;

   WHEREAS, as a condition to, and in connection with the execution of this
Agreement, certain stockholders of the Company have entered into a Voting
Agreement with Parent in the form attached hereto as Exhibit A; and

   WHEREAS, for federal income tax purposes, it is intended that the Merger
shall qualify as a reorganization under the provisions of section 368(a) of the
United States Internal Revenue Code of 1986, as amended (the "Code").

   NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth in this
Agreement and intending to be legally bound hereby, the parties hereto agree as
follows:

                                   ARTICLE I

                                   THE MERGER

   SECTION 1.1 The Merger. Upon the terms and subject to the conditions set
forth in this Agreement, and in accordance with the DGCL, at the Effective Time
(as defined in Section 1.2), Merger Sub shall be merged with and into the
Company. As a result of the Merger, the separate corporate existence of Merger
Sub shall cease and the Company shall continue as the surviving corporation of
the Merger (the "Surviving Corporation").

   SECTION 1.2 Effective Time. No later than three Business Days after the
satisfaction or, if permissible, waiver of the conditions set forth in Article
VII, the parties hereto shall cause the Merger to be consummated by filing a
certificate of merger (the "Certificate of Merger") with the Secretary of State
of the State of Delaware, in such form as required by, and executed in
accordance with, the relevant provisions of, the DGCL (the date and time of
such filing, or, if another date and time is specified in such filing, such
specified date and time, being the "Effective Time").

   SECTION 1.3 Effect of the Merger. At the Effective Time, the effect of the
Merger shall be as provided in the applicable provisions of the DGCL. Without
limiting the generality of the foregoing, and subject thereto, at the Effective
Time, except as otherwise provided herein, all the property, rights,
privileges, powers and franchises of the Company and Merger Sub shall vest in
the Surviving Corporation, and all debts, liabilities and duties of the Company
and Merger Sub shall become the debts, liabilities and duties of the Surviving
Corporation.

   SECTION 1.4 Certificate of Incorporation; By-laws. At the Effective Time,
the Certificate of Incorporation and the By-laws of the Surviving Corporation
shall be amended in their entirety to contain the

                                      A-1
<PAGE>

provisions set forth in the Certificate of Incorporation and By-laws of Merger
Sub, as in effect immediately prior to the Effective Time.

   SECTION 1.5 Directors and Officers. The directors of Merger Sub immediately
prior to the Effective Time shall be the initial directors of the Surviving
Corporation, each to hold office in accordance with the Certificate of
Incorporation and By-laws of the Surviving Corporation. The officers of Merger
Sub immediately prior to the Effective Time shall be the initial officers of
the Surviving Corporation, each to hold office in accordance with the
Certificate of Incorporation and By-laws of the Surviving Corporation.

                                   ARTICLE II

               CONVERSION OF SECURITIES; EXCHANGE OF CERTIFICATES

   SECTION 2.1 Conversion of Securities. At the Effective Time, by virtue of
the Merger and without any action on the part of Merger Sub, the Company or the
holders of any of the following securities:

     (a) Each share of common stock, par value $.001 per share, of the
  Company ("Company Common Stock") issued and outstanding immediately prior
  to the Effective Time (other than any shares of Company Common Stock to be
  cancelled pursuant to Section 2.1(b)) and each share of Series A
  Convertible Redeemable Preferred Stock, par value $.001 per share, of the
  Company ("Series A Preferred Stock"), Series B Convertible Redeemable
  Preferred Stock, par value $.001 per share, of the Company ("Series B
  Preferred Stock"), and Series C Convertible Redeemable Preferred Stock, par
  value $.001 per share, of the Company ("Series C Preferred Stock" and,
  together with the Series A Preferred Stock and the Series B Preferred
  Stock, the "Company Preferred Stock" and, together with the Company Common
  Stock, the "Company Capital Stock") issued and outstanding immediately
  prior to the Effective Time, shall be converted, subject to Section 2.3(e),
  into the right to receive:

       (A) to the extent that the Merger is treated for purposes of Section
    4 of the Company Certificate (as defined below) as a "liquidation,
    dissolution or winding up" of the Company,

         (i) in the case of each share of Company Common Stock, a fraction
      of a share of common stock, par value $3.00 per share, of Parent,
      including the corresponding percentage of a right to purchase shares
      of Junior Participating Preferred Stock, Series B, par value $100
      per share, of Parent pursuant to the Rights Agreement, dated
      November 5, 1998, between Parent and Harris Trust and Savings Bank,
      as Rights Agent (the "Parent Common Stock"), equal to (a)
      $430,000,000 minus (x) the Preferred Stock Liquidation Amount (as
      defined below) and (y) the Preferred Stock Participation Amount (as
      defined below), divided by $147.875 (the "Parent Stock Price"), and
      divided by (b) the difference of the number of Fully-Diluted Company
      Common Shares (as defined below and as identified in Section 3.3(a))
      minus the number of shares of Company Common Stock that would be
      issued assuming the conversion of all shares of Company Preferred
      Stock. The Preferred Stock Liquidation Amount is equal to the sum of
      Series A Convertible Preferred Liquidation Amount, Series B
      Convertible Preferred Liquidation Amount and Series C Convertible
      Preferred Liquidation Amount (in each case as such terms are defined
      in the Company Certificate). The fraction determined under this
      Section 2.1, as may be adjusted from time to time as set forth
      elsewhere herein, is called the "Liquidation Common Stock Exchange
      Ratio." "Fully-Diluted Company Common Shares" is equal to, as of the
      date hereof and without duplication with respect to clauses (i),
      (ii) and (iii) immediately below, the sum of: (i) the total number
      of shares of Company Common Stock outstanding, (ii) the total number
      of shares of Company Common Stock consisting of outstanding
      Restricted Stock and Founders Stock, (iii) the total number of
      shares of Company Common Stock that would be issued assuming the
      exercise, conversion or exchange, as applicable, of all outstanding
      Warrants, Company Options, or other rights to subscribe for,
      purchase or otherwise acquire any shares of Company Common Stock or
      any evidences of indebtedness convertible into capital stock of the
      Company, shares of stock, agreements, contracts or other securities
      of any other type or form

                                      A-2
<PAGE>

      which are convertible into or exchangeable or exercisable for, with
      or without payment of additional consideration, shares of Company
      Common Stock, either immediately or upon the arrival of a specified
      date or the happening of a specified event (in each case expressed
      on a Company Common Stock equivalent basis), and (iv) an additional
      10,000 shares of Company Common Stock;

         (ii) in the case of each share of Series A Preferred Stock, (x) a
      fraction of a share of Parent Common Stock equal to (a) the Series A
      Convertible Preferred Liquidation Amount divided by the Parent Stock
      Price, and divided by (b) the aggregate number of shares of Series A
      Preferred Stock outstanding at the Effective Time (the "Outstanding
      Series A Shares") and (y) a fraction of a share of Parent Common
      Stock equal to (A) the difference of three (3) times the Original
      Purchase Price (as defined in the Company Certificate) of the Series
      A Preferred Stock minus the Series A Convertible Preferred
      Liquidation Amount (such difference, the "Series A Participation
      Amount"), divided by the Parent Stock Price, divided by (B) the
      Outstanding Series A Shares (the exchange ratios set forth in
      clauses (x) and (y) of this subparagraph are referred to
      collectively as the "Series A Liquidation Exchange Ratios");

         (iii) in the case of each share of Series B Preferred Stock, (x)
      a fraction of a share of Parent Common Stock equal to (a) the Series
      B Convertible Preferred Liquidation Amount divided by the Parent
      Stock Price, and divided by (b) the aggregate number of shares of
      Series B Preferred Stock outstanding at the Effective Time (the
      "Outstanding Series B Shares") and (y) a fraction of a share of
      Parent Common Stock equal to (A) the difference of three times the
      Original Purchase Price of the Series B Preferred Stock minus the
      Series B Convertible Preferred Liquidation Amount (such difference,
      the "Series B Participation Amount"), divided by the Parent Stock
      Price, divided by (B) the Outstanding Series B Shares (the exchange
      ratios set forth in clauses (x) and (y) of this subparagraph are
      referred to collectively as the "Series B Liquidation Exchange
      Ratios"); and

         (iv) in the case of each share of Series C Preferred Stock, (x) a
      fraction of a share of Parent Common Stock equal to (a) the Series C
      Convertible Preferred Liquidation Amount divided by the Parent Stock
      Price, and divided by (b) the aggregate number of shares of Series C
      Preferred Stock outstanding at the Effective Time (the "Outstanding
      Series C Shares") and (y) a fraction of a share of Parent Common
      Stock equal to (A) the difference of three times the Original
      Purchase Price of the Series C Preferred Stock minus the Series C
      Convertible Preferred Liquidation Amount (such difference, the
      "Series C Participation Amount" and, together with the Series A
      Participation Amount and the Series B Participation Amount, the
      "Preferred Stock Participation Amount"), divided by the Parent Stock
      Price, divided by (B) the Outstanding Series C Shares (the exchange
      ratios set forth in clauses (x) and (y) of this subparagraph are
      referred to collectively as the "Series C Liquidation Exchange
      Ratios");

       (B) to the extent that holders of at least fifty-five percent (55%)
    of the Company Preferred Stock, voting together as a single class on an
    as converted basis, elect pursuant to Section 4(c) of the Company
    Certificate that the Merger not be treated as a "liquidation,
    dissolution or winding up" of the Company,

         (i) in the case of each share of Company Common Stock, a fraction
      of a share of Parent Company Stock equal to 0.1022485 (the "Merger
      Common Stock Exchange Ratio" and, together with the Liquidation
      Common Stock Exchange Ratio, the Series A Liquidation Exchange
      Ratios, the Series B Liquidation Exchange Ratios and the Series C
      Liquidation Exchange Ratios, the "Exchange Ratios");

         (ii) in the case of each share of Series A Preferred Stock, a
      fraction of a share of Parent Company Stock equal to the product of
      (a) the number of Company Common Shares into which
      such share of Series A Preferred Stock is then convertible into
      pursuant to Section 5(h) of the Company Certificate multiplied by
      (b) the Merger Common Stock Exchange Ratio;

                                      A-3
<PAGE>

         (iii) in the case of each share of Series B Preferred Stock, a
      fraction of a share of Parent Company Stock equal to the product of
      (a) the number of Company Common Shares into which such share of
      Series B Preferred Stock is then convertible into pursuant to
      Section 5(h) of the Company Certificate multiplied by (b) the Merger
      Common Stock Exchange Ratio; and

         (iv) in the case of each share of Series C Preferred Stock, a
      fraction of a share of Parent Company Stock equal to the product of

      Series C Preferred Stock is then convertible into pursuant to
      Section 5(h) of the Company Certificate multiplied by (b) the Merger
      Common Stock Exchange Ratio.

provided, however, that, in any event, if between the date of this Agreement
and the Effective Time the outstanding shares of Parent Common Stock, Company
Common Stock or Company Preferred Stock shall have been changed into a
different number of shares or a different class, by reason of any stock
dividend, subdivision, reclassification, recapitalization, split, combination
or exchange of shares, each Exchange Ratio shall be correspondingly adjusted to
reflect such stock dividend, subdivision, reclassification, recapitalization,
split, combination or exchange of shares. All such shares of Company Common
Stock or Company Preferred Stock shall no longer be outstanding and shall
automatically be canceled and retired and shall cease to exist, and each
certificate previously representing any such shares shall thereafter represent
the right to receive a certificate representing the shares of Parent Common
Stock into which such Company Common Stock or Company Preferred Stock was
converted in the Merger. Certificates previously representing shares of Company
Common Stock or Company Preferred Stock shall be exchanged for certificates
representing whole shares of Parent Common Stock issued in consideration
therefor upon the surrender of such certificates in accordance with the
provisions of Section 2.3, without interest.

     (b) Each share of Company Common Stock held in the treasury of the
  Company immediately prior to the Effective Time shall be canceled and
  extinguished without any conversion thereof and no payment shall be made
  with respect thereto.

     (c) Each share of common stock, par value $0.01 per share, of Merger Sub
  issued and outstanding immediately prior to the Effective Time shall be
  converted into and exchanged for one newly and validly issued, fully paid
  and nonassessable share of common stock of the Surviving Corporation.

     (d) 290,786 shares of Parent Common Stock which stockholders of record
  of the Company (the "Stockholders") immediately prior to the Effective Time
  shall be entitled to receive immediately as of the Effective Time and into
  which their shares of Company Capital Stock were converted pursuant to this
  Section 2.1 (the "Escrow Shares") shall be deposited in escrow pursuant to
  Section 2.2 and shall be held and disposed of in accordance with the terms
  of the Escrow Agreement (the "Escrow Agreement"), to be entered into on the
  Effective Time, by and among Parent, the Stockholder Representative, as
  defined below in Article VIII, and Harris Trust and Savings Bank or another
  institution designated by Parent and the Company as the Escrow Agent (the
  "Escrow Agent"), a form of which is attached hereto as Exhibit B; the
  Stockholders shall be entitled to receive immediately as of the Effective
  Time the remaining shares of Parent Common Stock into which the Company
  Capital Stock were converted pursuant to this Section 2.1 (the "Initial
  Shares"). The Escrow Shares and the Initial Shares shall together be
  referred to herein as the "Merger Shares."

   SECTION 2.2 Escrow. At the Effective Time, Parent shall deliver to the
Escrow Agent a certificate (issued in the name of the Escrow Agent or its
nominee) representing the Escrow Shares for the purpose of securing and as the
sole remedy for satisfying the indemnification obligations of the Stockholders
set forth in this Agreement. The Escrow Shares shall be held by the Escrow
Agent under the Escrow Agreement pursuant to the terms thereof. The Escrow
Shares shall be held as a trust fund and shall not be subject to any lien,
attachment, trustee process or any other judicial process of any creditor of
any party, and shall be held and disbursed solely for the purposes and in
accordance with the terms of this Agreement and the Escrow Agreement. The
adoption of this Agreement and the approval of the Merger by the Stockholders
shall

                                      A-4
<PAGE>

constitute approval of the Escrow Agreement and of all of the arrangements
relating thereto, including without limitation the placement of the Escrow
Shares in escrow and the appointment of the Stockholder Representative.

   SECTION 2.3 Exchange of Certificates.

   (a) Exchange Agent. As of the Effective Time, Parent shall deposit, or shall
cause to be deposited, with Harris Trust and Savings Bank or another bank or
trust company designated by Parent and reasonably satisfactory to the Company
(the "Exchange Agent"), for the benefit of the holders of shares of Company
Capital Stock, for exchange in accordance with this Article II, through the
Exchange Agent, certificates representing the Initial Shares, together with
cash in lieu of fractional shares and any dividends or distributions with
respect thereto (the "Exchange Fund") issuable pursuant to Section 2.1 in
exchange for shares of Company Capital Stock that are subject to conversion as
provided herein. The Exchange Agent shall deliver the Parent Common Stock
contemplated to be issued pursuant to Section 2.1 out of the Exchange Fund in
accordance with the terms of the Exchange Agreement to be entered into on the
Effective Date between Parent and the Exchange Agent (the "Exchange
Agreement"). Except as contemplated by Section 2.2(e) hereof, the Exchange Fund
shall not be used for any other purpose.

   (b) Exchange Procedures. Within five Business Days after the Effective Time,
but in any event after the receipt by the Exchange Agent from the Company of
the documents set forth in Section 1(a) of the Exchange Agreement, Parent shall
instruct the Exchange Agent to mail to each holder of record of a certificate
or certificates which immediately prior to the Effective Time represented
outstanding shares of Company Capital Stock (the "Certificates") (1) a letter
of transmittal (which shall specify that delivery shall be effected, and risk
of loss and title to the Certificates shall pass, only upon proper delivery of
the Certificates to the Exchange Agent and shall be in customary form) and (2)
instructions for use in effecting the surrender of the Certificates in exchange
for certificates representing shares of Parent Common Stock. Upon surrender of
a Certificate for cancellation to the Exchange Agent together with such letter
of transmittal, duly executed, and such other documents as may be required
pursuant to such instructions, the holder of such Certificate shall be entitled
to receive in exchange therefor (x) a certificate representing that number of
whole Initial Shares which such holder has the right to receive in respect of
the shares of Company Capital Stock formerly owned by such holder, (y) cash in
lieu of fractional shares of Parent Common Stock to which such holder is
entitled pursuant to Section 2.3(e), and (z) any dividends or other
distributions to which such holder is entitled pursuant to Section 2.3(c), and
the Certificate so surrendered shall forthwith be canceled. No interest will be
paid or accrued on any cash in lieu of fractional shares or on any unpaid
dividends and distributions payable to holders of Certificates. In the event of
a transfer of ownership of shares of Company Capital Stock which is not
registered in the transfer records of the Company, a certificate representing
the proper number of shares of Parent Common Stock may be issued to a
transferee if the Certificate representing such shares of Company Capital Stock
is presented to the Exchange Agent, accompanied by all documents required to
evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid. Until surrendered as contemplated by this
Section 2.3, each Certificate shall be deemed at any time after the Effective
Time to represent only the right to receive upon such surrender the certificate
representing shares of Parent Common Stock, cash in lieu of any fractional
shares of Parent Common Stock to which such holder is entitled pursuant to
Section 2.3(e) and any dividends or other distributions to which such holder is
entitled pursuant to Section 2.3(c).

   (c) Distributions with Respect to Unexchanged Shares of Parent Common Stock.
No dividends or other distributions declared or made after the Effective Time
with respect to Parent Common Stock with a record date after the Effective Time
shall be paid to the holder of any unsurrendered Certificate with respect to
the shares of Parent Common Stock represented thereby, and no cash payment in
lieu of fractional shares shall be paid to any such holder pursuant to Section
2.3(e), unless and until the holder of such Certificate shall surrender such
Certificate. Subject to the effect of escheat, tax or other applicable Laws,
following surrender of any such Certificate, there shall be paid to the holder
of the certificates representing whole shares of Parent Common

                                      A-5
<PAGE>

Stock issued in exchange therefor, without interest, (1) promptly, the amount
of any cash payable with respect to a fractional share of Parent Common Stock
to which such holder is entitled pursuant to Section 2.3(e) and the amount of
dividends or other distributions with a record date after the Effective Time
theretofore paid with respect to such whole shares of Parent Common Stock and
(2) at the appropriate payment date, the amount of dividends or other
distributions, with a record date after the Effective Time but prior to
surrender and a payment date occurring after surrender, payable with respect to
such whole shares of Parent Common Stock.

   (d) No Further Rights in Company Common Stock. All shares of Parent Common
Stock issued upon conversion of the shares of Company Capital Stock in
accordance with the terms hereof (including any cash paid pursuant to Section
2.3(c) or (e)) shall be deemed to have been issued in full satisfaction of all
rights pertaining to such shares of Company Capital Stock.

   (e) No Fractional Shares.

     (1) No certificates or scrip representing fractional shares of Parent
  Common Stock shall be issued upon the surrender for exchange of
  Certificates, no dividend or distribution with respect to Parent Common
  Stock shall be payable on or with respect to any fractional share and such
  fractional share interests will not entitle the owner thereof to any rights
  of a stockholder of Parent.

     (2) As promptly as practicable after the Effective Time, the Exchange
  Agent shall determine the excess of (A) the number of full shares of Parent
  Common Stock delivered to the Exchange Agent by Parent pursuant to Section
  2.3(a) over (B) the aggregate number of full shares of Parent Common Stock
  to be distributed to holders of Company Capital Stock pursuant to Section
  2.3(b) (such excess being herein called the "Excess Shares"). As soon as
  practicable after the Effective Time, the Exchange Agent, as agent for such
  holders of Parent Common Stock, shall sell the Excess Shares at then
  prevailing prices on the New York Stock Exchange, Inc. (the "NYSE"), all in
  the manner provided in paragraph (3) of this Section 2.3(e).

     (3) The sale of the Excess Shares by the Exchange Agent shall be
  executed on the NYSE through one or more member firms of the NYSE and shall
  be executed in round lots to the extent practicable. Until the net proceeds
  of any such sale or sales have been distributed to such holders of Company
  Capital Stock, the Exchange Agent will hold such proceeds in trust for such
  holders of Company Capital Stock as part of the Exchange Fund. The Company
  shall pay all commissions, transfer taxes and other out-of-pocket
  transaction costs of the Exchange Agent incurred in connection with such
  sale or sales of Excess Shares. In addition, the Company shall pay the
  Exchange Agent's compensation and expenses in connection with such sale or
  sales. The Exchange Agent shall determine the portion of such net proceeds
  to which each holder of Company Capital Stock shall be entitled, if any, by
  multiplying the amount of the aggregate net proceeds by a fraction, the
  numerator of which is the amount of the fractional share interest to which
  such holder of Company Capital Stock is entitled (after taking into account
  all shares of Parent Common Stock to be issued to such holder) and the
  denominator of which is the aggregate amount of fractional share interests
  to which all holders of Company Capital Stock are entitled.

     (4) As soon as practicable after the determination of the amount of
  cash, if any, to be paid to holders of Company Capital Stock with respect
  to any fractional share interests, the Exchange Agent shall promptly pay
  such amounts to such holders of Company Capital Stock subject to and in
  accordance with the terms of Section 2.3(c).

   (f) Termination of Exchange Fund. Any portion of the Exchange Fund that
remains undistributed to the holders of Company Common Stock for eleven months
after the Effective Time shall be delivered to Parent, upon demand, and any
holders of Company Common Stock who have not theretofore complied with this
Article II shall thereafter look only to Parent for the shares of Parent Common
Stock, any cash in lieu of fractional shares of Parent Common Stock to which
they are entitled pursuant to Section 2.3(e) and any dividends or other
distributions with respect to Parent Common Stock to which they are entitled
pursuant to Section 2.3(c), in each case, without any interest thereon.

                                      A-6
<PAGE>

   (g) No Liability. Neither Parent nor the Company shall be liable to any
holder of shares of Company Common Stock for any such shares of Parent Common
Stock (or dividends or distributions with respect thereto) or cash from the
Exchange Fund delivered to a public official pursuant to any abandoned
property, escheat or similar Law.

   (h) Lost Certificates. If any Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Certificate to be lost, stolen or destroyed and, if required by Parent,
the posting by such person of a bond, in such reasonable amount as Parent may
direct, as indemnity against any claim that may be made against it with respect
to such Certificate, the Exchange Agent will issue in exchange for such lost,
stolen or destroyed Certificate the shares of Parent Common Stock, any cash in
lieu of fractional shares of Parent Common Stock to which the holders thereof
are entitled pursuant to Section 2.3(e) and any dividends or other
distributions to which the holders thereof are entitled pursuant to Section
2.3(c), in each case, without any interest thereon.

   (i) Withholding. Parent or the Exchange Agent shall be entitled to deduct
and withhold from the consideration otherwise payable pursuant to this
Agreement to any holder of Company Common Stock such amounts as Parent or the
Exchange Agent are required to deduct and withhold under the Code, or any
provision of state, local or foreign tax law, with respect to the making of
such payment. To the extent that amounts are so withheld by Parent or the
Exchange Agent, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of Company Common Stock in respect
of whom such deduction and withholding was made by Parent or the Exchange
Agent. With respect to any Stockholder who is not a foreign person, Parent
shall receive a certificate of nonforeign status in the form of Exhibit
2.3(i)(A) on or prior to the Effective Time. Parent shall receive on or prior
to the Effective Time a certificate from the Company in the form of Exhibit
2.3(i)(B) that the Company is not a "United States Real Property Holding
Company" within the meaning of Code section 897(c)(2).

   SECTION 2.4 Stock Transfer Books. At the Effective Time, the stock transfer
books of the Company shall be closed and thereafter, there shall be no further
registration of transfers of shares of Company Common Stock theretofore
outstanding on the records of the Company. From and after the Effective Time,
the holders of certificates representing shares of Company Common Stock
outstanding immediately prior to the Effective Time shall cease to have any
rights with respect to such shares of Company Common Stock except as otherwise
provided herein or by Law. On or after the Effective Time, any Certificates
presented to the Exchange Agent or Parent for any reason shall be converted
into the shares of Parent Common Stock, any cash in lieu of fractional shares
of Parent Common Stock to which the holders thereof are entitled pursuant to
Section 2.3(e) and any dividends or other distributions to which the holders
thereof are entitled pursuant to Section 2.3(c).

   SECTION 2.5 Stock Options. Prior to the Effective Time, the Company and
Parent shall take such action as may be necessary to cause each unexpired and
unexercised option to purchase shares of Company Common Stock (each, a "Company
Option") under the 1997 Stock Incentive Plan (the "Company Stock Option Plan"),
a true and complete copy of which has heretofore been provided to Parent by the
Company, to be exercisable solely for such number of shares of Parent Common
Stock as is equal to the number of shares of Company Common Stock that could
have been purchased under such Company Option immediately prior to the
Effective Time multiplied by the Common Stock Exchange Ratio (rounded down to
the nearest whole number of shares of Parent Common Stock), at a price per
share of Parent Common Stock equal to the per-share option exercise price
specified in the Company Option divided by the Common Stock Exchange Ratio
(rounded up to the nearest whole cent). Such Company Option shall otherwise be
subject to the same terms and conditions (including provisions regarding
vesting and the acceleration thereof) as in effect at the Effective Time. At
the Effective Time, (1) all references to the Company in the Company Stock
Option Plan and in the related stock option agreements shall be deemed to refer
to Parent and (2) Parent shall assume all of the Company's obligations with
respect to Company Options as so amended.

                                      A-7

   SECTION 2.6 Restricted and Founders Stock. The parties acknowledge that
shares of Company Common Stock awarded or issued pursuant to a restricted stock
agreement under the Company Stock Option Plan (the "Restricted Stock") or
pursuant to a founders stock agreement identified in Section 3.3(a) of the
Company Disclosure Schedule (the "Founders Stock") shall be converted into
Parent Common Stock in accordance with the provisions of Section 2.1(a);
provided, however, that the Restricted Stock and Founders Stock that will
remain unvested as of the Effective Time shall remain subject to the vesting,
forfeiture or repurchase restrictions and other provisions set forth in the
restricted stock agreements and the founders stock agreement, as applicable,
that applied to the Restricted Stock and Founders Stock prior to the Effective
Time.

   SECTION 2.7 Appraisal Rights. Notwithstanding anything in this Agreement to
the contrary, shares of Company Capital Stock (the "Dissenting Shares") that
are issued and outstanding immediately prior to the Effective Time and are held
by stockholders of the Company who did not vote in favor of the Merger and who
comply with all of the relevant provisions of Section 262 of the DGCL (the
"Dissenting Stockholders") shall not be converted into or be exchangeable for
the right to receive any shares of Parent Common Stock, unless and until such
stockholders shall have failed to perfect or shall have effectively withdrawn
or lost their rights to appraisal under the DGCL. The Company shall give Parent
(i) prompt notice of any written demands for appraisal of any shares of Company
Capital Stock, attempted withdrawals of such demands and any other instruments
served pursuant to the DGCL and received by the Company relating to
stockholders' rights of appraisal, and (ii) the opportunity to direct all
negotiations and proceedings with respect to demands for appraisal under the
DGCL. Neither the Company nor the Surviving Corporation shall, except with the
prior written consent of Parent, voluntarily make any payment with respect to,
or settle or offer to settle, any such demand for payment. If any Dissenting
Stockholder shall fail to perfect or shall have effectively withdrawn or lost
the right to dissent, then (i) as of the occurrence of such event, such
holder's Dissenting Shares shall cease to be Dissenting Shares and shall be
converted into and represent the right to receive the Merger Shares issuable
pursuant to Section 2.1, and (ii) promptly following the occurrence of such
event, Parent shall deliver to the Exchange Agent a certificate representing
90% of the Merger Shares to which such holder is entitled pursuant to Section
2.1 and shall deliver to the Escrow Agent a certificate representing the
remaining 10% of the Merger Shares to which such holder is entitled pursuant to
Section 2.1 (which shares shall be considered Escrow Shares for all purposes of
this Agreement).

                                  ARTICLE III

                 REPRESENTATIONS AND WARRANTIES OF THE COMPANY

   Except as set forth in the Disclosure Schedule delivered by the Company to
Parent prior to the execution of this Agreement (the "Company Disclosure
Schedule"), which identifies exceptions only by specific Section references,
the Company hereby represents and warrants to Parent and Merger Sub as follows:

   SECTION 3.1 Organization and Qualification; Subsidiaries. The Company has
been duly incorporated and is validly existing and in good standing under the
laws of the State of Delaware and has the requisite power and authority and all
necessary governmental approvals to own, lease and operate its properties and
to carry on its business as it is now being conducted, except where the failure
to be so incorporated, existing or in good standing or to have such power,
authority and governmental approvals would not, individually or in the
aggregate, reasonably be expected to have a Company Material Adverse Effect.
The Company is duly qualified or licensed to do business, and is in good
standing, in each jurisdiction where the character of the properties owned,
leased or operated by it or the nature of its business makes such qualification
or licensing or good standing necessary. The Company does not have any
subsidiaries and does not hold any investment or interest of any kind in a
partnership or joint venture of any kind. For purposes of this Agreement,
"Company Material Adverse Effect" means any change affecting, or condition
having an effect on, the Company that is, or would reasonably be expected to
be, materially adverse to the assets, liabilities, business, condition
(financial or otherwise) or results of operations of the Company other than any
change or condition relating to the economy (including any change in the
semiconductor industry generally) or securities markets in general, and not
specifically relating to the Company.

   SECTION 3.9 Employee Benefit Plans and Executive Compensation.

   (a) Section 3.9(a) of the Company Disclosure Schedule sets forth a true and
complete list as of the date hereof of each "employee pension benefit plan" (as
such term is defined in Section 3(2) of ERISA), "employee welfare benefit plan"
(as such term is defined in Section 3(1) of ERISA), material personnel or
payroll policy (including vacation time, holiday pay, service awards, moving
expense reimbursement programs and sick leave) or material fringe benefit,

other incentive plan (including any equity or equity-based plan), top hat plan
or deferred compensation plan, salary reduction agreement, change-of-control
agreement, employment agreement, consulting agreement, collective bargaining
agreement, indemnification agreement, or retainer agreement, or any other
benefit plan, policy, program, arrangement, agreement or contract, whether or

independent contractor, or any beneficiary or dependent thereof (including,
without limitation, any "employee benefit plan", as defined in Section 3(3) of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA")),
maintained, or contributed to, by the Company or to which the Company is
required to contribute (the "Company Benefit Plans"). With respect to each of
the Company Benefit Plans, the Company has heretofore delivered or made
available to Parent a true, correct and complete copy of: (1) each writing
constituting a part of such Company Benefit Plans, including without limitation
all plan documents, trust

                                      A-12
<PAGE>

agreements, and insurance contracts and other funding vehicles; (2) the most
recent Annual Report (Form 5500 Series) and accompanying schedule, if any; (3)
the current summary plan description and any material modifications thereto, if
any (in each case, whether or not required to be furnished under ERISA); (4)
the most recent annual financial report, if any; (5) the most recent actuarial

Revenue Service ("IRS"), if any. Except as specifically provided in the
foregoing documents delivered to Parent, there are no amendments to any Company
Benefit Plans that have been adopted or approved nor has the Company undertaken
to make any such amendments or to adopt or approve any new Plan.

   (b) No Company Benefit Plans are subject to Title IV of ERISA, Section 302
of ERISA or Section 412 or 4971 of the Code. No Company Benefit Plans are a
"multiemployer pension plan" (as such term is defined in Section 3(37) of
ERISA) (a "Multiemployer Plan") or a plan that has two or more contributing
sponsors at least two of whom are not under common control, within the meaning
of Section 4063 of ERISA (a "Multiple Employer Plan"). Neither the Company nor
any of its ERISA Affiliates (as defined below) has (1) at any time during the
last six years, contributed to or been obligated to contribute to any
Multiemployer Plan or Multiple Employer Plan, or (2) incurred any withdrawal
liability to a Multiemployer Plan as a result of a complete or partial
withdrawal from such Multiemployer Plan that has not been satisfied in full.
Except as set forth in Section 3.9(b) of the Company Disclosure Schedule, there
does not now exist, nor do any circumstances exist that could result in, any
liability that would be a liability of the Company following the Effective Time
(1) under Title IV of ERISA, (2) under Section 302 of ERISA, (3) under Sections
412 and 4971 of the Code, or (4) as a result of a failure to comply with the
continuation coverage requirements of Section 601 et seq. of ERISA and Section
4980B of the Code.

   (c) Except as set forth in Section 3.9(c) of the Company Disclosure
Schedule, each of the Company Benefit Plans has been operated and administered
in all material respects in accordance with applicable Laws and administrative
rules and regulations of any Governmental Entity, including, but not limited
to, ERISA and the Code. Each of the Company Benefit Plans intended to be
"qualified" within the meaning of Section 401(a) of the Code has received a
favorable determination letter as to such qualification from the IRS, and no
event has occurred, either by reason of any action or failure to act, which
would cause the loss of any such qualification. Except as set forth in Section
3.9(c) of the Company Disclosure Schedule, no Company Benefit Plans provide
benefits, including, without limitation, death or medical benefits (whether or
not insured), with respect to current or former employees of the Company beyond
their retirement or other termination of service, other than (1) coverage
mandated by applicable Law, (2) death benefits or retirement benefits under any
"employee pension plan" (as such term is defined in Section 3(2) of ERISA), or
(3) deferred compensation benefits accrued as liabilities on the books of the
Company. All contributions or other amounts payable by the Company as of the
Effective Time with respect to each of the Company Benefit Plans in respect of
current or prior plan years will have been paid or accrued by such time in
accordance with GAAP.

Schedule and has made available to Parent true and complete copies of (1) all
severance and employment agreements with directors, executive officers, key
employees or consultants of the Company; (2) all severance programs and
policies of the Company with or relating to its employees; and (3) all plans,
programs, agreements and other arrangements of the Company with or relating to
its employees, directors or consultants which contain change in control
provisions. Except as set forth in Section 3.9(d) of the Company Disclosure
Schedule, neither the execution and delivery of this Agreement nor the
consummation of the transactions contemplated hereby will (either alone or in
conjunction with any other event, such as termination of employment) (A) result
in any payment or profit (including, without limitation, severance,
unemployment compensation, golden parachute or otherwise) becoming due or
increased to any director, employee or consultant of the Company or affiliate
from the Company or affiliate under any Company Benefit Plans or otherwise, (B)
increase any benefits otherwise payable under any Company Benefit Plans or (C)
result in any acceleration of the time of payment or vesting of any
compensation or benefits. No individual who is a party to an employment
agreement listed in Section 3.9(a) of the Company Disclosure Schedule or any
change of control employment agreement with the

                                      A-13
<PAGE>

Company has terminated employment or been terminated, nor has any event
occurred that could give rise to a termination event, in either case under
circumstances that has given, or could give, rise to a payment or severance
obligation on the part of the Company under such agreement.

   (e) Except as disclosed in Section 3.9(e) of the Company Disclosure
Schedule:

   (1) With respect to each of the Company Benefit Plans, there are no claims
or other proceedings pending or threatened with respect to the assets thereof
(other than routine claims for benefits), and which could reasonably give rise
to any liability, claim or other proceeding against any Company Benefit Plans,
any fiduciary or plan administrator or other Person dealing with any Company
Benefit Plans or the assets of any such Company Benefit Plans.

   (2) With respect to each of the Company Benefit Plans, no Person: (A) has
entered into any "prohibited transaction," as such term is defined in ERISA or
the Code and the regulations, administrative rulings and case law thereunder
that is not exempt under Code Section 4975 or ERISA Section 408 (or any
administrative class exemption issued thereunder); (B) has breached a fiduciary
obligation or violated Sections 402, 403, 405, 503, 510 or 511 of ERISA; (C)
has any liability for any failure to act or comply in connection with the
administration or investment of the assets of such plans; or (D) has engaged in
any transaction or otherwise acted with respect to such plans in such a manner
which could subject Parent, the Company or any employee of the Company to
liability under Section 409 or 502 of ERISA or Sections 4972 or 4976 through
4980B of the Code.

   (3) Each of the Company Benefit Plans (other than any stock option plan) may
be amended, terminated, modified or otherwise revised by the Company, as
provided in the Company Benefit Plans as so amended, other than benefits
protected under Section 411(d) of the Code, on and after the Effective Time,
without further material liability to the Company (excluding ordinary
administrative expenses and routine claims for benefit plans), including, but
not limited to, any withdrawal liability under ERISA for any Multiemployer Plan
or any liability under any Company Benefit Plans subject to Title IV of ERISA.

   (4) The requirements of the Consolidated Omnibus Budget Reconciliation Act
of 1985 and the Health Insurance Portability and Accountability Act, the
requirements of the Family Medical Leave Act of 1993, as amended, the
requirements of the Women's Health and Cancer Rights Act, the requirements of
the Newborns' and Mothers' Health Protection Act of 1996, or any amendment to
each such act, or any similar provisions of state law applicable to its
employees, have, in all material respects, been satisfied with respect to each
of the Company Benefit Plans.

   (5) All contributions, payments, premiums, expenses, reimbursements or
accruals for all periods ending prior to or as of the Effective Time for each
of the Company Benefit Plans (including periods from the first day of the then
current plan year to the Effective Time), including without limitation such
Company Benefits Plans providing for vacation time, shall have been made or
accrued on the Financial Statements (in accordance with GAAP, including FAS 87,
88, 106 and 112) and each such plan otherwise does not have nor could have any
unfunded liability (including benefit liabilities as defined in Section
4001(a)(16) of ERISA) which is not reflected on the Financial Statements. The
same shall be true for all periods ending as of the Effective Time for each of
the Company Benefit Plans.

   (6) The Company has determined that each contractor, consultant, or leased
employee who has performed services for the Company prior to the date hereof or
who will perform services prior to the Effective Time is not an employee for
all purposes under ERISA, the Code, the Company Benefit Plans, and other
applicable Laws, there are no claims or proceedings pending or threatened
relating to a claim for benefits by such contractor, consultant or leased
employee under ERISA, the Code, the Company Benefit Plans, or other applicable
Laws with respect to such services performed prior to the date hereof or which
will be performed prior to the Effective Time and there is no violation of Law
or otherwise which could serve as the basis of any such claim or proceeding.

reasonable efforts, and shall take any such actions reasonably requested by the

Parent subsidiaries, and their respective businesses resulting, or which could
reasonably be expected to result after the Effective Time, from the failure to
obtain such consent.

   (c) From the date of this Agreement until the Effective Time, the Company

Merger and the other transactions contemplated by this Agreement not to be
satisfied or (b) the failure of the Company or Parent, as the case may be, to
comply with or satisfy any covenant, condition or agreement to be complied with
or satisfied by it pursuant to this Agreement which would reasonably be
expected to result in any condition to the obligations of any party to effect
the Merger and the other transactions contemplated by this Agreement not to be
satisfied; provided, however, that the delivery of any notice pursuant to this
Section 6.7 shall not cure any breach of any representation or warranty
requiring disclosure of such matter prior to the date of this Agreement or
otherwise limit or affect the remedies available hereunder to the party
receiving such notice.

   SECTION 6.8 Warrants. Each of the Company and Parent shall use its best
efforts so that each outstanding warrant (as set forth on Section 6.8 of the
Company Disclosure Schedule) to purchase shares of Company Capital Stock (the

to the NYSE a listing application covering the shares of Parent Common Stock to
be issued in the Merger and shall use reasonable best efforts to cause such
shares to be approved for listing on such exchange, subject to official notice

best efforts to cause the Merger to qualify, and will not knowingly take any
actions or cause any actions to be taken which could reasonably be expected to
prevent the Merger from qualifying, as a reorganization under the provisions of
section 368(a) of the Code.

the Effective Time Parent shall provide for registration of shares of Parent
Common Stock subject to the Company Options, Restricted Stock and Founders
Stock by filing with the SEC a registration statement on Form S-8 (or any
successor form) with respect to such shares of Parent Common Stock. Such
registration shall be kept effective (and the current status of the prospectus
required thereby shall be maintained in accordance with the relevant
requirements of the Securities Act and the Exchange Act) at least for so long
as such Company Options, Restricted Stock and Founders Stock remain
outstanding.

   (b) Prior to the Effective Time, the Board of Directors of the Company shall
adopt by resolution an amendment to the Company Stock Option Plan, which
amendment shall be approved by Parent (such approval to not be unreasonably
withheld), to provide that one-half of the Company Options that are unvested
prior to the Effective Time and held by any person employed by or providing
services to the Company at the Effective Time shall become fully vested and
exercisable as of the Effective Time, and the other one-half of such Company
Options shall become vested over the 12-month period immediately following the
Effective Time in equal amounts on a monthly basis.

  such statement shall be true and correct in all respects giving effect to
  such standard) as of the date hereof and as of the Effective Time as though
  made on and as of the Effective Time, except that those representations and
  warranties which address matters only as of a particular date shall remain
  true and correct in all material respects (except that where any statement
  in a representation or warranty expressly includes a standard of
  materiality, such statement shall be true and correct in all respects
  giving effect to such standard) as of such date. Parent shall have received

  the Company to that effect.

  complied in all material respects with all agreements and covenants
  required by this Agreement to be performed or complied with by it on or

  Strawn, special tax advisors to Parent, in form and substance reasonably
  satisfactory to Parent, based upon facts, representations and assumptions
  set forth in such opinion which are consistent with the state of facts

  treated for federal income tax purposes as a reorganization within the
  meaning of section 368(a) of the Code. The issuance of such opinion shall
  be conditioned upon the receipt by such tax counsel of customary
  representation letters from Parent, Merger Sub and the Company.

  "cold comfort" letters of PricewaterhouseCoopers LLP, dated the date on
  which the Registration Statement shall become effective and a date within

  customary in scope and substance for comfort letters delivered by
  independent public accountants.

contemplated in this Agreement is also subject to the following conditions:

     (a) Representations and Warranties. Each of the representations and

<PAGE>

  that where any statement in a representation or warranty expressly includes

  and assumptions in such opinion, which are consistent with the state of

  treated for federal income tax purposes as a reorganization within the
  meaning of section 368(a) of the Code. The issuance of such opinion shall
  be conditioned upon the receipt by such tax counsel of customary
  representation letters from Parent, Merger Sub and the Company.

     (d) Registered Shares. All shares of Parent Common Stock issuable to the
  Stockholders in the Merger shall have been registered under the Securities
  Act.

                                  ARTICLE VIII

                                INDEMNIFICATION

   SECTION 8.1 Survival of Representations and Warranties. The representations
and warranties set forth in Articles III and IV shall survive for a period of
12 months after the Effective Time; provided, however, that if a notice is
given as provided herein before expiration of the representation or warranty,
then notwithstanding the expiration thereof any claim based on such
representation or warranty shall survive until the resolution of such claim.

   SECTION 8.2 Indemnification by Parent. (a) Parent agrees, subject to the
other terms and conditions of this Agreement, to indemnify the Stockholders
against, and hold them harmless from, all losses, claims, fines, penalties,
amounts paid in settlement, liabilities, costs and expenses (including, without
limitation, reasonable attorney and expert fees) of and damages to the
Stockholders related to or arising out of the breach of the representation and
warranty of Parent contained in Section 4.3 hereof.

   (b) No claim may be made after the Effective Time against Parent for
indemnification pursuant to Section 8.2(a) unless the aggregate of all
liabilities and damages of the Stockholders (exclusive of legal fees incurred
in connection with pursuing such claim) with respect to Section 8.2(a) along
with all liability of Parent to the Stockholders shall in the aggregate exceed
$100,000; provided, however, that under no circumstances shall Parent liability
under Section 8.2(a) exceed $43,000,000. This Section 8.2(b) is not intended to
address the liability of Parent for any breach of any representation, warranty
or covenant if the Merger is not consummated.

   (c) The Stockholders agree to give Parent through the Stockholder
Representative prompt written notice of any claim, assertion, event or
proceeding by or in respect of a third party of which they have knowledge
concerning any liability or damage as to which it may request indemnification
hereunder (a "Claim Notice" which contains (a) a description and the amount
(the "Claim Amount") of such indemnification request, and (ii) a statement that
the Stockholders are entitled to indemnification hereunder and a reasonable
explanation of the basis therefore (a copy of such Claim Notice shall also be
delivered to the Escrow Agent); provided, however, that no delay on the part of
the Stockholder Representative in notifying Parent shall relieve Parent from
any liability or obligation hereunder unless Parent can demonstrate that it was
damaged by such delay. Parent will not consent to the entry of any judgment
with respect to the matter, or enter into any settlement which does not include
a provision whereby the plaintiff or claimant in the matter releases the
Stockholders from all liability with respect thereto without the written
consent of the Stockholder Representative. Parent shall have the right

                                      A-34
<PAGE>

to direct, at its own expense and through counsel of its own choosing
(reasonably satisfactory to Parent), the defense or settlement of any such
claim or proceeding; the Stockholders Representative may participate in such
defense, but in such case the expenses of the Stockholder Representative shall
be paid by the Stockholder Representative; provided, however, that if the
Stockholder Representative delivers to Parent a written opinion of counsel to
the effect that there exists an actual conflict of interest between Parent and
the Stockholder Representative with respect to such claim, or such claim or
liability involves the possibility of criminal sanctions or criminal liability
to the Stockholder Representative, the Stockholder Representative shall be
entitled to participate in the defense of such claim or liability at the
expense of Parent. The Stockholder Representative shall provide Parent with
access to all records and personnel of the Stockholders and the Company
relating to any such claim, assertion, event or proceeding during normal
business hours and shall otherwise cooperate with and assist, at Parent's
request, Parent in the defense or settlement thereof, and Parent shall
reimburse the Stockholder Representative for all reasonable out-of-pocket
expenses in connection therewith. If Parent elects to direct the defense of any
such claim or proceeding, the Stockholder Representative shall not pay, or
permit to be paid, any part of any claim or demand arising from such asserted
liability unless Parent consents in writing to such payment (such consent not
to be unreasonably withheld or delayed) or unless Parent, subject to the last
sentence of this Section 8.2(c), withdraws from the defense of such asserted
liability or unless a final judgment from which no appeal may be taken by or on
behalf of Parent is entered against the Stockholder Representative for such
liability. If Parent shall fail to assume the defense of such claim in the
manner provided above, or if, after commencing or undertaking any such defense,
fails to prosecute or withdraws from such defense, the Stockholder
Representative shall have the right to undertake the defense or settlement
thereof, and the Stockholder Representative may defend against, or enter into
any settlement with respect to, the matter in any manner the Stockholder
Representative reasonably may deem appropriate.

   SECTION 8.3 Indemnification by the Stockholders. (a) The Stockholders agree,
subject to the other terms and conditions of this Agreement and the Escrow
Agreement, to indemnify Parent (and Parent's directors, officers, employees,
controlling persons, affiliates, successors, assigns, representatives, advisors
and legal counsel (collectively, the "Parent Indemnitees")) against, and hold
then harmless from, all losses, claims, fines, penalties, amounts paid in
settlement, liabilities, costs and expenses (including, without limitation,
reasonable attorney and expert fees) of and damages to Parent related to or
arising out of (i) the untruth, inaccuracy or incompleteness as of the date
hereof or on the Effective Time of any representation or warranty of the
Company contained in this Agreement or the Company Disclosure Schedule (without
regard to any "materiality", "Company Material Adverse Effect", "substantial
compliance" or similar exception or qualifier) (or in any document, writing,
certificate, or data delivered by the Company under this Agreement) or the
failure by the Company or any Stockholder to perform any of its covenants or
obligations hereunder or contained in this Agreement or the Company Disclosure
Schedule (or in any document, writing, certificate, data or financial
statements delivered by the Company or the Stockholders under this Agreement),
(ii) the fees, expenses and disbursements in excess of $2,500,000 in accordance
with the provisions of Section 9.5 hereof, (iii) (A) any governmental action,
order, directive, administrative proceeding or ruling; (B) personal or bodily
injuries (including death) or damage (including loss of use) to any premises
(public or private); (C) cleanup, remediation, investigation or monitoring of
any pollution or contamination of or adverse effects on human health or the
environment; or (D) any violation or alleged violation of Environmental Laws
existing prior to the Effective Time, and (iv) those matters set forth on
Section 8.3 of the Company Disclosure Schedule. The Stockholders agree to
establish the Escrow Fund pursuant to Section 8.3(c) for the sole purpose of
satisfying the Stockholders' indemnification obligations hereunder.

   (b) No claim may be made after the Effective Time against the Escrow Fund
for indemnification pursuant to Section 8.3(a) unless the aggregate of all
liabilities and damages (exclusive of (i) legal fees incurred in connection
with pursuing such claim, (ii) any breach of Section 3.23 (except for the
$75,000 adjustment referred to in Section 5.1(a)(xi)), and (iii) any breach of
Section 9.5) of Parent with respect to Section 8.3(a) and all liability of the
Stockholders to Parent shall in the aggregate exceed $100,000; provided,
however, that the aggregate amount available to indemnify the Parent Indemnitee
shall not exceed the value of the Escrow Fund. No Stockholder shall be required
to indemnify the Parent Indemnitee for an amount that would exceed

                                      A-35
<PAGE>

such Stockholder's pro rata share of the Escrow Shares deposited in the Escrow
Fund. The Stockholders shall not have any right of contribution from the
Company with respect to any loss claimed by the Parent Indemnitee after the
Effective Time. This Section 8.3(b) is not intended to address the liability of
the Company for any breach of any representation, warranty or covenant if the
Merger is not consummated.

   (c) As security for the indemnity provided for in this Section 8.3 and to
provide security to satisfy any contingencies arising from the representations
and warranties of the Company hereunder, each of the Stockholders receiving the
Parent Common Stock in the Merger will be deemed to have received and deposited
with the Escrow Agent the Escrow Shares (plus any additional shares as may be
issued upon any stock split, stock dividend or recapitalization effected by
Parent after the Effective Time with respect to the Escrow Shares). The Escrow
Shares will be deposited with and will be held by the Escrow Agent, such
deposit to constitute an escrow fund (the "Escrow Fund") to be governed by the
terms set forth in the Escrow Agreement. The portion of the Escrow Fund
contributed on behalf of each Stockholder shall be in proportion to the
aggregate Merger Shares which such Stockholder would otherwise be entitled
under Section 2.1.

   (d) The Parent Indemnitees agree to give the Stockholder Representative,
with a copy to the Escrow Agent, prompt Claim Notice which shall contain
information similar to those described in Section 8.2(c); provided, however,
that no delay on the part of any Parent Indemnitee in notifying the Stockholder
Representative shall relieve the Stockholders from any liability or obligation
hereunder unless (and then solely to the extent that) the Stockholders can
demonstrate that they were damaged by such delay. The Stockholder
Representative will not consent to the entry of any judgment with respect to
the matter, or enter into any settlement which does not include a provision
whereby the plaintiff or claimant in the matter releases the Parent Indemnitee
from all liability with respect thereto, without the written consent of the
Parent Indemnitee. The Stockholder Representative shall have the right to
direct, at its own expense and through counsel of its own choosing (reasonably
satisfactory to the Parent Indemnitee), the defense or settlement of any such
claim or proceeding; the Parent Indemnitee may participate in such defense, but
in such case the expenses of the Parent Indemnitee shall be paid by the Parent
Indemnitee; provided, however, that if the Parent Indemnitee delivers to the
Stockholder Representative a written opinion of counsel to the effect that
there exists an actual conflict of interest among the Stockholders and the
Parent Indemnitee with respect to such claim, or such claim or liability
involves the possibility of criminal sanctions or criminal liability to the
Parent Indemnitee, the Parent Indemnitee shall be entitled to participate in
the defense of such claim or liability at the expense of the Parent Indemnitee.
Parent shall provide the Stockholder Representative with access to its records
and personnel relating to any such claim, assertion, event or proceeding during
normal business hours and shall otherwise cooperate with and assist, at the
Stockholder Representative's request, the Stockholder Representative in the
defense or settlement thereof, and the Stockholder Representative shall
reimburse Parent for all its reasonable out-of-pocket expenses in connection
therewith. If the Stockholder Representative elects to direct the defense of
any such claim or proceeding, Parent shall not pay, or permit to be paid, any
part of any claim or demand arising from such asserted liability unless the
Stockholder Representative consents in writing to such payment (such consent
not to be unreasonably withheld or delayed) or unless the Stockholder
Representative, subject to the last sentence of this Section 8.3(d), withdraws
from the defense of such asserted liability or unless a final judgment from
which no appeal may be taken by or on behalf of the Stockholder Representative
is entered against Parent for such liability. If the Stockholder Representative
shall fail to assume the defense of such claim in the manner provided above, or
if, after commencing or undertaking any such defense, fail to prosecute or
withdraws from such defense, Parent shall have the right to undertake the
defense or settlement thereof, and the Parent Indemnitee may defend against, or
enter into any settlement with respect to, the matter in any manner the Parent
Indemnitee reasonably may deem appropriate.

   SECTION 8.4 Stockholder Representative; Approval of Stockholders.

   (a) Laurence G. Walker shall be constituted and appointed as agent
("Stockholder Representative") for and on behalf of the Stockholders to give
and receive notices and communications, to agree to, negotiate, enter into
settlements and compromises of, and demand arbitration and comply with orders
of courts and awards of

                                      A-36
<PAGE>

arbitrators with respect to such claims, and to take all actions necessary or
appropriate in the judgment of the Stockholder Representative for the
accomplishment of the foregoing. Such agency may be changed by a majority vote
or by the written consent of the majority of the Stockholders from time to time
upon not less than ten Business Days' prior written notice to Parent. In the
event of the death or disability (for more than 15 Business Days) of the
Stockholder Representative or his resignation as Stockholder Representative and
until a successor Stockholder Representative shall be appointed as provided
above or in Section 7(b) of the Escrow Agreement, the then President of the
Company shall act as the Stockholder Representative pending the appointment of
the successor Stockholder Representative. No bond shall be required of the
Stockholder Representative, and the Stockholder Representative shall receive no
compensation for his/her services. Notices or communications to or from the
Stockholder Representative shall constitute notice to or from each of the
Stockholders.

   (b) The approval by the Stockholders of the Merger shall be deemed to be
approval of the terms of the provisions of this Article VIII, including the
appointment of the Stockholder Representative.

   (c) A decision, act, consent or instruction of the Stockholder
Representative shall constitute a decision of all Stockholders and shall be
final, binding and conclusive upon each such Stockholder, and Parent may rely
upon any such decision, act, consent or instruction of the Shareholder
Representative as being the decision, act, consent or instruction of each
Stockholder. Parent is hereby relieved from any liability to any person for any
acts done by it in accordance with such decision, act, consent or instruction
of the Stockholder Representative.

                                   ARTICLE IX

any representation, warranty, covenant or other agreement contained herein), if
there has been a breach by the Company of any of its representations,
warranties, covenants or agreements contained in this Agreement, or any such
representation and warranty shall have become untrue, in any such case such

  breach of any representation, warranty, covenant or other agreement
  contained herein), if there has been a breach by Parent of any of its
  representations, warranties, covenants or agreements contained in this
  Agreement, or any such representation and warranty shall have become
  untrue, in any such case such that Section 7.3(a) or Section 7.3(b) will
  not be satisfied and such breach or condition has not been promptly cured
  within 30 days following receipt by Parent of written notice of such
  breach;

   (c) by either Parent or the Company if any decree, permanent injunction,
judgment, order or other action by any court of competent jurisdiction, any
arbitrator or any Governmental Entity preventing or prohibiting consummation of
the Merger shall have become final and nonappealable (so long as the party
seeking termination is not in breach of Section 6.5(a) hereof); or

   (d) by either Parent or the Company if the Merger shall not have been
consummated before May 31, 2000; provided that the Company or Parent shall have
the right to automatically extend such date to June 30, 2000 by providing
written notice thereof to the other party so long as the party requesting such
extension is not then in material breach of any representation, warranty,
covenant or other agreement contained herein; and provided, further that any
extension requested by either Parent or the Company beyond June 30, 2000 shall
be considered and negotiated by the Company and Parent in good faith.

all parties hereto; provided, however, that, after approval of the Merger by

requires further approval by the Stockholders. This Agreement may not be
amended except by an instrument in writing signed by the parties hereto.

                 [LETTERHEAD OF DEUTSCHE BANK SECURITIES INC.]

                               February 17, 2000

Board of Directors
C-Port Corporation
One High Street
North Andover, MA 01845

Gentlemen:

   Deutsche Bank Securities Inc. ("Deutsche Bank") has acted as financial
advisor to C-Port Corporation ("C-Port") in connection with the proposed merger
of C-Port and Motorola, Inc. ("Motorola") pursuant to the Agreement and Plan of
Merger, dated February 17, 2000, among C-Port, Motorola and CP Acquisition
Corp., a wholly owned subsidiary of Motorola ("Merger Sub") (the "Merger
Agreement"), which provides, among other things, for the merger of Merger Sub
with and into C-Port (the "Transaction"), as a result of which C-Port will
become a wholly owned subsidiary of Motorola.

   As set forth more fully in the Merger Agreement, as a result of the
Transaction and the Voting Agreements, each share of the Common Stock, par
value $.001 per share, of C-Port ("C-Port Common Stock") not owned directly or
indirectly by Motorola or C-Port will be converted into the right to receive
 .1022485 shares (the "Exchange Ratio") of Common Stock, par value $3.00 per
share, of Motorola ("Motorola Common Stock"). In addition, shareholders holding
approximately 56% of the equity securities of C-Port with voting rights have
entered into Voting Agreements pursuant to which they have agreed to vote their
shares in favor of the Transaction. Ten percent of the number of shares of
Motorola Common Stock that the shareholders of C-Port Common Stock shall be
entitled to receive shall be deposited in escrow for a period of one year
pursuant to the terms of the Escrow Agreement to be entered into at closing,
which escrow constitutes the sole recourse of Motorola in respect of the
Indemnity obligations of the Merger Agreement. The terms and conditions of the
Transaction are more fully set forth in the Merger Agreement.

   You have requested Deutsche Bank's opinion, as investment bankers, as to the
fairness, from a financial point of view, to the shareholders of C-Port of the
Exchange Ratio.

   In connection with Deutsche Bank's role as financial advisor to C-Port, and
in arriving at its opinion, Deutsche Bank has reviewed certain publicly
available financial and other information concerning Motorola and C-Port and
certain internal analyses and other information furnished to it by Motorola and
C-Port. Deutsche Bank has also held discussions with members of the managements
of Motorola and C-Port regarding the businesses and prospects of their
respective companies and the joint prospects of a combined company. In
addition, Deutsche Bank has (i) reviewed the reported prices and trading
activity for Motorola Common Stock (ii) compared certain financial and stock
market information for Motorola with similar information for certain other
companies whose securities are publicly traded, (iii) reviewed the financial
terms of certain recent business combinations which it deemed comparable in
whole or in part, (iv) reviewed the terms of the Merger Agreement and certain
related documents, and (v) performed such other studies and analyses and
considered such other factors as it deemed appropriate.

   Deutsche Bank has not assumed responsibility for independent verification
of, and has not independently verified, any information, whether publicly
available or furnished to it, concerning Motorola or C-Port, including, without
limitation, any financial information, forecasts or projections considered in
connection with the rendering of its opinion. Accordingly, for purposes of its
opinion, Deutsche Bank has assumed and relied upon the accuracy and
completeness of all such information and Deutsche Bank has not conducted a
physical inspection of any of the properties or assets, and has not prepared or
obtained any independent evaluation or appraisal of any of the assets or
liabilities, of Motorola or C-Port. With respect to the financial forecasts and

                                      B-1
<PAGE>

projections of C-Port made available to Deutsche Bank and used in its analyses,
Deutsche Bank has assumed that they have been reasonably prepared on bases
reflecting the best currently available estimates and judgments of the
management of C-Port as to the matters covered thereby. In rendering its
opinion, Deutsche Bank expresses no view as to the reasonableness of such
forecasts and projections or the assumptions on which they are based. Deutsche
Bank's opinion is necessarily based upon economic, market and other conditions
as in effect on, and the information made available to it as of, the date
hereof.

   For purposes of rendering its opinion, Deutsche Bank has assumed that, in
all respects material to its analysis, the representations and warranties of C-
Port, Merger Sub and Motorola contained in the Merger Agreement are true and
correct, C-Port, Merger Sub and Motorola will each perform all of the covenants
and agreements to be performed by it under the Merger Agreement and all
conditions to the obligations of each of C-Port, Merger Sub and Motorola to
consummate the Transaction will be satisfied without any waiver thereof.
Deutsche Bank has also assumed that all material governmental, regulatory or
other approvals and consents required in connection with the consummation of
the Transaction will be obtained and that in connection with obtaining any
necessary governmental, regulatory or other approvals and consents, or any
amendments, modifications or waivers to any agreements, instruments or orders
to which either C-Port or Motorola is a party or is subject or by which it is
bound, no limitations, restrictions or conditions will be imposed or
amendments, modifications or waivers made that would have a material adverse
effect on C-Port or Motorola or materially reduce the contemplated benefits of
the Transaction to C-Port. In addition, you have informed Deutsche Bank, and
accordingly for purposes of rendering its opinion Deutsche Bank has assumed,
that the Transaction will be tax-free to each of C-Port and Motorola and their
respective stockholders and that the Transaction will be accounted for as a
purchase.

   This opinion is addressed to, and for the use and benefit of, the Board of
Directors of C-Port and is not a recommendation to the stockholders of C-Port
to approve the Transaction. This opinion is limited to the fairness, from a
financial point of view, to the shareholders of C-Port of the Exchange Ratio,
and Deutsche Bank expresses no opinion as to the merits of the underlying
decision by C-Port to engage in the Transaction.

   Deutsche Bank will be paid a fee for its services as financial advisor to C-
Port in connection with the Transaction, a substantial portion of which is
contingent upon consummation of the Transaction. We are an affiliate of
Deutsche Bank AG (together with its affiliates, the "DB Group"). One or more
members of the DB Group have, from time to time, provided investment banking
and other financial services to Motorola, and to the respective affiliates and
shareholders of C-Port and Motorola, for which it has received compensation. In
the ordinary course of business, members of the DB Group may actively trade in
the securities and other instruments and obligations of Motorola for their own
accounts and for the accounts of their customers. Accordingly, the DB Group may
at any time hold a long or short position in such securities, instruments and
obligations.

   Based upon and subject to the foregoing, it is Deutsche Bank's opinion as
investment bankers that the Exchange Ratio is fair, from a financial point of
view, to the shareholders of C-Port.

                                          Very truly yours,

                                          /s/ Deutsche Bank Securities Inc.

                                          DEUTSCHE BANK SECURITIES INC.

                                Voting Agreement

February 17, 2000

Motorola, Inc.

Attention:

Ladies and Gentlemen:

   Each of the undersigned understands that Motorola, Inc. ("Parent"), CP

entering into an Agreement and Plan of Merger, dated as of the date hereof (the
"Merger Agreement"), providing for, among other things, a merger of Merger Sub
with and into the Company (the "Merger"), in which all of the outstanding
shares of common stock, par value $.001 per share, of the Company (the "Company
Common Stock") will be exchanged for shares of common stock, par value $3.00
per share, of Parent. Terms that are defined in the Merger Agreement but that
are not defined in this letter agreement will have the meaning ascribed to them
in the Merger Agreement.

   Each of the undersigned is a Stockholder of the Company and is entering into
this letter agreement to induce you to enter into the Merger Agreement and to
consummate the transactions contemplated thereby.

   Each of the undersigned confirms its agreement with you as follows:

       1. The undersigned represents, warrants and agrees that Schedule I
annexed hereto sets forth (a) the number of shares of Company Common Stock (the
"Shares") of which the undersigned is the record or beneficial owner and (b)
the number of shares of Company Preferred Stock (set forth on Schedule I
according to the number of shares owned in each class of Company Preferred
Stock) and options and warrants (such Preferred Stock and options and warrants
being collectively referred to herein as the "Convertible Securities") which
are exercisable for the number of shares of Company Common Stock set forth
therein, of which the undersigned is the record or beneficial owner. The
undersigned represents, warrants and agrees that, as of the date hereof, the
undersigned owns such Shares and Convertible Securities, free and clear of all
liens, charges, encumbrances, voting agreements and commitments of every kind
except those contained in the restricted stock agreements with the Company.

       2. The undersigned represents and warrants that the undersigned has all
necessary power and authority to enter into this letter agreement, and that
this agreement is the legal, valid and binding agreement of the undersigned,
and is enforceable against the undersigned in accordance with its terms.

       3. Except, if necessary, for the filing of a Pre-merger Notification and
Report Form pursuant to HSR Act, (A) no filing with, and no permit,
authorization, consent or approval of, any-state or federal public body or
authority is necessary for the execution of this letter agreement by the
undersigned and the consummation by the undersigned of the transactions
contemplated hereby and by the Merger Agreement and (B) none of the execution
and delivery of this letter agreement and the Merger Agreement by the
undersigned, the consummation by the undersigned of the transactions
contemplated hereby or thereby or compliance by the undersigned with any of the
provisions hereof or thereof shall (i) result in a violation or breach of, or
constitute (with or without notice or lapse of time or both) a default (or give
rise to any third party right of termination, cancellation, material
modification or acceleration of any obligation or to a loss of a material
benefit) under any of the terms, conditions or provisions of any Contract to
which the undersigned is a party or by which the undersigned may be bound, or
(ii) violate any Law, order, injunction, judgment, decree or award of any
court, Governmental Entity or arbitrator.

       4. The undersigned agrees that it will not, and will not agree to,
contract to or sell or otherwise transfer or dispose of any of the Shares, or
any interest therein, or Convertible Securities, or any Shares obtained upon
the exercise of Convertible Securities, or any other securities convertible
into or exchangeable

                                      C-1
<PAGE>

for Company Common Stock or any voting rights with respect thereto, other than
(i) pursuant to the Merger or (ii) with your prior written consent.

       5. The undersigned agrees that all of the Shares (including any Shares
issued upon exercise of any Convertible Securities exercised prior to the
record date referred to below) and the shares of Company Preferred Stock that
are beneficially owned by the undersigned at the record date for any meeting of
Stockholders called to consider and vote to approve the Merger Agreement, the
Merger and other transactions contemplated by the Merger Agreement will be
voted by the undersigned in favor thereof and the undersigned shall refrain
from voting the Shares and the shares of Company Preferred Stock in favor of
any proposal involving the sale of substantially all of the assets or capital
stock, merger or business combination involving the Company and any other
person other than Parent.

       6. The undersigned hereby grants to, and appoints, Parent, the Secretary
of Parent, any Assistant Secretary of Parent and the Chief Financial Officer of
Parent, in their respective capacities as officers of Parent, and any
individual who shall hereafter succeed to any such office of Parent, and any
other designee of Parent, each of them individually, the undersigned's
irrevocable proxy and attorney-in-fact (with full power of substitution) to
vote the undersigned's Shares and the shares of Company Preferred Stock, and to
sign the undersigned's name to any written consent of the holders of the Shares
and the shares of Company Preferred Stock with respect thereto, in order to
give effect to the covenants of the undersigned contained in this letter
agreement. The undersigned agrees that this proxy is irrevocable until this
letter agreement is terminated in accordance with paragraph 12 hereof and
coupled with an interest and will take such further action or execute such
other instruments as may be necessary to effectuate the intent of this proxy
and hereby revokes any proxy previously granted by the undersigned with respect
to the Shares and the shares of Company Preferred Stock.

the Merger Agreement and the transactions contemplated thereby. The undersigned

or otherwise in connection with the Merger with respect to any and all shares
of Company Capital Stock held by the undersigned of record or beneficially
owned.

       10. Each of the undersigned does hereby appoint Laurence G. Walker as
the representative of each of these and other Stockholders in accordance with
Article VIII of the Merger Agreement.

       11. In the event any of the undersigned is a director of the Company,
notwithstanding anything to the contrary in this letter agreement, nothing in
this letter agreement is intended or shall be construed to require any of the
undersigned to take or in any way limit any action that any of the undersigned
may take to discharge his fiduciary duties as a director of the Company;
provided, however, that no such duty shall excuse the undersigned as a
Stockholder from its obligations as a Stockholder to vote the Shares, to the
extent that they may be so voted, or otherwise perform any obligation as herein
provided and to otherwise comply with the terms and conditions of this letter
agreement.

       12. This letter agreement may be terminated at the option of any party
hereto at any time after the earliest of (a) termination of the Merger
Agreement in accordance with its terms, and (b) the day following the Effective
Time provided that any termination pursuant to this clause (b) shall not
terminate paragraph 8 hereof. Notwithstanding any other provision hereof, this
letter shall terminate automatically on the date of the termination of the
Merger Agreement.

       13. This agreement shall be governed by, and construed in accordance
with, the laws of the State of Delaware, without reference to principles of
conflicts of law. This letter agreement may be executed in any

                                      C-2

number of counterparts and by the parties hereto on separate counterparts but
all such counterparts shall together constitute one and the same letter
agreement.

   Please confirm that the foregoing correctly states the understanding between
us and you by signing and returning to us a counterpart hereof.

                                          Very truly yours,

                        Delaware General Corporation Law
                            Delaware Code Annotated
                             Title 8. Corporations
                       Chapter 1. General Corporation Law
                     Subchapter IX. Merger or Consolidation

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 Section
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 Section 251 (other than a merger effected pursuant to
Section 251(g) of this title), Section 252, Section 254, Section 257, Section
258, Section 263 or Section 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 Section 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
  Sections 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 in
    respect thereof) 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.

                                      D-1

     (3) In the event all of the stock of a subsidiary Delaware corporation
  party to a merger effected under Section 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.

   (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 subsection (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 Section 228
  or Section 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 stockholders
  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

                                      D-2
<PAGE>

  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 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 stockholders. 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 20 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

                                      D-3
<PAGE>

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.

   (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.

                            Form of Escrow Agreement

   This Escrow Agreement is entered into as of [        ], 2000 (this
"Agreement") by and among Motorola, Inc., a Delaware corporation ("Parent"),
[Laurence G. Walker] (the "Stockholder Representative"), and Harris Trust and
Savings Bank (the "Escrow Agent").

   WHEREAS, Parent, C-Port Corporation (the "Company") and a subsidiary of
Parent ("Merger Sub") have entered into an Agreement and Plan of Merger dated
as of February [   ], 2000 (the "Merger Agreement"), pursuant to which Merger
Sub will be merged (the "Merger") with and into the Company which, as the
surviving corporation (the "Surviving Corporation"), will become a wholly-owned
subsidiary of Parent (the defined terms used but not defined herein shall have
the meaning ascribed to such terms in the Merger Agreement);

   WHEREAS, the Merger Agreement provides that an escrow fund (the "Escrow
Fund") will be established to secure certain indemnification and expense
obligations of the Stockholders to Parent;

   WHEREAS, the Escrow Agent is willing to act in the capacity of Escrow Agent
hereunder subject to, and upon the terms and conditions of, this Agreement; and

   WHEREAS, the parties hereto desire to establish the terms and conditions
pursuant to which the Escrow Fund will be established and maintained;

   NOW, THEREFORE, the parties hereto hereby agree as follows:

     1. Consent of Company Stockholders; Designation of Escrow Agent. The
  Stockholders have by virtue of their approval of the Merger Agreement
  consented to: (a) the establishment of the escrow to secure the
  Stockholders' indemnification obligations under Article VIII of the Merger
  Agreement in the manner set forth herein, (b) the appointment of the
  Stockholder Representative as their representative for purposes of this
  Agreement and as attorney-in-fact and agent for and on behalf of each
  Stockholder, and the taking by the Stockholder Representative of any and
  all actions and the making of any decisions required or permitted to be
  taken or made by them under this Agreement and (c) all of the other terms,
  conditions and limitations contained in the Merger Agreement and in this
  Agreement. Parent and the Stockholder Representative, on behalf of the
  Stockholders, hereby mutually designate and appoint Harris Trust and
  Savings Bank to serve as Escrow Agent for the purposes set forth herein.
  The Escrow Agent hereby accepts such appointment and agrees to act in
  furtherance of the terms and conditions herein.

     2. Escrow and Indemnification.

       (a) Escrow of Shares. As of the Effective Time, Parent shall deposit
    with the Escrow Agent a certificate for [      ] Escrow Shares issued
    in the name of the Escrow Agent or its nominee. Parent may from time to
    time deposit with the Escrow Agent additional shares of Parent Common
    Stock pursuant to the terms of the Merger Agreement. The Escrow Shares
    shall be held as a trust fund and shall not be subject to any lien,
    attachment, trustee process or any other judicial process of any
    creditor of any party hereto. The Escrow Agent agrees to hold the
    Escrow Shares in the Escrow Fund, subject to the terms and conditions
    of this Agreement.

       (b) Indemnification. The Stockholders have agreed in Article VIII of
    the Merger Agreement to indemnify and hold harmless Parent to the
    extent set forth therein. The Escrow Shares shall secure such indemnity
    and payment obligations of the Stockholders, subject to the
    limitations, and in the manner provided, in the Merger Agreement and
    this Agreement. It is further acknowledged and agreed that the Escrow
    Fund established hereunder to secure the indemnity and payment
    obligations of the Stockholders under Article VIII of the Merger
    Agreement shall be Parent's sole and exclusive remedy in satisfaction
    of such indemnity and payment obligations.

                                      E-1
<PAGE>

       (c) Dividends, Etc. Any cash dividends or property or any securities
    distributed in respect of or in exchange for any of the Escrow Shares,
    whether by way of stock dividends, stock splits or otherwise
    (collectively, the "Dividends"), shall be delivered to or issued in the
    name of the Escrow Agent or its nominee, and the Escrow Agent shall
    hold the Dividends in the Escrow Fund. Such securities shall be
    considered Escrow Shares for purposes hereof and such cash or other
    property shall be considered part of the Escrow Fund.

       (d) Voting of Shares. The Stockholder Representative shall have the
    right, in its sole discretion, on behalf of the Stockholders, to direct
    the Escrow Agent in writing as to the exercise of any voting rights
    pertaining to the Escrow Shares, and the Escrow Agent shall comply with
    any such written instructions. In the absence of such instructions, the
    Escrow Agent shall not vote any of the Escrow Shares. The Stockholder
    Representative shall have no obligation to solicit consents or proxies
    from the Stockholders for purposes of any such vote.

       (e) Transferability. The respective interests of the Stockholders in
    the Escrow Shares and the Dividends shall not be assignable or
    transferable, other than by operation of law. Notice of any such
    assignment or transfer by operation of law shall be given to the Escrow
    Agent and Parent, and no such assignment or transfer shall be valid
    until such notice is given.

     3. Distribution of Escrow Shares.

       (a) The Escrow Agent shall distribute the Escrow Shares and the
    Dividends only in accordance with (i) a written instrument delivered to
    the Escrow Agent that is executed by both Parent and the Stockholder
    Representative and that instructs the Escrow Agent as to the
    distribution of some or all of the Escrow Shares and the Dividends,
    (ii) an order of a court of competent jurisdiction, a copy of which is
    delivered to the Escrow Agent by either Parent or the Stockholder
    Representative, that instructs the Escrow Agent as to the distribution
    of some or all of the Escrow Shares and the Dividends, (iii) the
    provisions of Section 3(b) hereof, or (iv) the provisions of Section
    3(c) hereof.

       (b) Within five Business Days after the first anniversary hereof
    (the "Termination Date"), the Escrow Agent shall distribute to the
    Stockholders all of the Escrow Shares and the Dividends from the Escrow
    Fund, registered, in the case of the Escrow Shares, in the name of the
    Stockholders. Notwithstanding the foregoing, if Parent has previously
    delivered to the Escrow Agent a copy of a Claim Notice and the Escrow
    Agent has not received written notice of the resolution of the claim
    covered thereby, the Escrow Agent shall retain in escrow after the
    Termination Date such number of Escrow Shares and the Dividends as have
    a Value (as defined in Section 4 below) equal to 125% of the Claimed
    Amount covered by such Claim Notice. Any Escrow Shares so retained in
    escrow shall be distributed only in accordance with the terms of
    clauses (i) or (ii) of Section 3(a) hereof.

       (c) (i) If at any time Parent determines the existence of a cause of
    action with respect to matters set forth in Section 8.3 of the Merger
    Agreement, Parent shall notify the Stockholder Representative and the
    Escrow Agent by delivery to the Stockholder Representative and the
    Escrow Agent of the Claim Notice.

         (ii) The determination of Parent as set forth in the Claim Notice
      shall be deemed final and binding upon the Stockholder
      Representative and the Escrow Agent, and the Escrow Agent shall
      deliver the number of Escrow Shares and the Dividends specified in
      the Claim Notice pursuant to the instructions set forth in the Claim
      Notice on the twentieth (20th) Business Day after its receipt of the
      Claim Notice unless within fifteen (15) Business Days after delivery
      of the Claim Notice to the Escrow Agent a written notice ("Notice of
      Objection") is given by the Stockholder Representative to Parent and
      the Escrow Agent of the Stockholder Representative's objection to
      the Claim Notice setting forth the basis of its objection to the
      Claim Notice.

         (iii) If the Notice of Objection is given as provided above, the
      Escrow Agent shall keep the number of Escrow Shares and the
      Dividends indicated in the Claim Notice until the Escrow Agent
      receives written joint instructions from the Stockholder
      Representative and Parent as Stockholder Representative and Parent
      shall promptly consult with each other with respect to their
      disagreement for purposes of prompt and amicable resolution of the
      dispute.

                                      E-2
<PAGE>

         (iv) If the Stockholder Representative and Parent are able to
      resolve the dispute, Parent and the Stockholder Representative shall
      promptly provide the Escrow Agent with joint written instructions
      executed by the Stockholder Representative and Parent with respect
      to the distribution of the Escrow Shares and the Dividends subject
      to the dispute. If the instructions are not precise, the Escrow
      Agent, in its sole and absolute discretion, shall (i) request
      additional instructions and (ii) keep the Escrow Shares and the
      Dividends until receipt of such additional instructions.

         (v) If the Stockholder Representative and Parent are unable to
      reach agreement within the thirty (30) days after the Notice of
      Objection has been given to Parent and the Escrow Agent, the dispute
      shall be referred for resolution to a court of competent
      jurisdiction, whose decision shall be final, binding and non-
      appealable. Once such decision is rendered, the Stockholder
      Representative and Parent shall deliver to the Escrow Agent joint
      written instructions executed by the Stockholder Representative and
      Parent pursuant to the terms of the decision. Upon receipt of such
      instructions, the Escrow Agent shall promptly release the Escrow
      Shares and the Dividends subject to the dispute pursuant to such
      instructions.

       (d) Any distribution of all or a portion of the Escrow Shares and
    the Dividends to the Stockholders shall be made by delivery of (i)
    stock certificates issued in the name of the Stockholders covering such
    percentage of the Escrow Shares, including for purposes hereof the
    Dividends in the form of shares of Parent Common Stock, being
    distributed as is calculated in accordance with the percentages set
    forth opposite such holders' respective names on Attachment A attached
    hereto and (ii) cash and other property, if any; provided, however,
    that such Attachment A shall be appropriately revised by Parent in the
    event Parent deposits additional Escrow Shares and the Dividends with
    the Escrow Agent following the date of this Agreement. With respect to
    the Escrow Shares, distributions to the Stockholders shall be made by
    mailing stock certificates to such holders at their respective
    addresses shown on Attachment A (or such other address as may be
    provided in writing to the Escrow Agent by the Stockholder
    Representative). No fractional Escrow Shares shall be distributed to
    Stockholders pursuant to this Agreement. Instead, the number of shares
    that each Stockholder shall receive shall be rounded up or down to the
    nearest whole number (provided that the Stockholder Representative
    shall have the authority to effect such rounding in such a manner that
    the total number of whole Escrow Shares to be distributed equals the
    number of Escrow Shares then held in the Escrow Account).

     4. Valuation of Escrow Shares. For purposes of this Agreement, the
  "Value" per share shall be the average of the last reported sale price per
  share of the common stock of Parent Common Stock on the NYSE over the five
  consecutive trading days ending on the last Business Day immediately
  preceding the date of the distribution of the Escrow Shares by the Escrow
  Agent.

     5. Fees and Expenses of Escrow Agent. Parent shall pay all of the fees
  and expenses of the Escrow Agent for the services to be rendered by the
  Escrow Agent hereunder.

     6. Limitation of Escrow Agent's Liability.

       (a) The Escrow Agent shall incur no liability with respect to any
    action taken or suffered by it in reliance upon any notice, direction,
    instruction, consent, statement or other documents believed by it to be
    genuine and duly authorized, nor for other action or inaction except
    its own willful misconduct or gross negligence. The Escrow Agent shall
    not be responsible for the validity or sufficiency of this Agreement.
    In all questions arising under the Escrow Agreement, the Escrow Agent
    may rely on the advice of counsel, and the Escrow Agent shall not be
    liable to anyone for anything done, omitted or suffered in good faith
    by the Escrow Agent based on such advice. The Escrow Agent shall not be
    required to take any action hereunder involving any expense unless the
    payment of such expense is made or provided for in a manner reasonably
    satisfactory to it. In no event shall the Escrow Agent be liable for
    indirect, punitive, special or consequential damages.

                                      E-3
<PAGE>

       (b) Parent and the Stockholders hereby, jointly and severally, agree
    to indemnify the Escrow Agent for, and hold it harmless against, any
    loss, liability or expense incurred without gross negligence or willful
    misconduct on the part of Escrow Agent, arising out of or in connection
    with its carrying out of its duties hereunder. Parent, on the one hand,
    and the Stockholders, on the other hand, shall each be liable for one-
    half of such amounts.

     7. Liability and Authority of Stockholder Representative; Successors and
  Assignees.

       (a) The Stockholder Representative shall incur no liability to the
    Stockholders with respect to any action taken or suffered by them in
    reliance upon any note, direction, instruction, consent, statement or
    other documents believed by them to be genuinely and duly authorized,
    nor for other action or inaction except their own willful misconduct or
    gross negligence. The Stockholder Representative may, in all questions
    arising under the Escrow Agreement, rely on the advice of counsel and
    the Stockholder Representative shall not be liable to the Stockholders
    of anything done, omitted or suffered in good faith by the Stockholder
    Representative based on such advice.

       (b) In the event of the death or disability (for more than 15
    Business Days) of the Stockholder Representative, his resignation as
    the Stockholder Representative or otherwise, a successor Stockholder
    Representative shall be elected by a majority vote or written consent
    of the Stockholders upon not less than ten Business Days prior written
    notice to Parent, with each such Stockholder (or his, her or its
    successors or assigns) to be given a vote equal to the number of votes
    represented by the shares of stock of the Company held by such
    Stockholder immediately prior to the Effective Time; provided, however,
    that the then President of the Company shall act as the Stockholder
    Representative pending the appointment of a successor Stockholder
    Representative. Each successor Stockholder Representative shall have
    all of the power, authority, rights and privileges conferred by this
    Agreement upon the original Stockholder Representative, and the term
    "Stockholder Representative" as used herein shall be deemed to include
    successor Stockholder Representative.

       (c) The Stockholder Representative, acting jointly but not singly,
    shall have full power and authority to represent the Stockholders, and
    their successors, with respect to all matters arising under this
    Agreement and all actions taken by any Stockholder Representative
    hereunder shall be binding upon the Stockholders, and their successors,
    as if expressly confirmed and ratified in writing by each of them.
    Without limiting the generality of the foregoing, the Stockholder
    Representative, acting by a majority thereof, shall have full power and
    authority to interpret all of the terms and provisions of this
    Agreement, to compromise any claims asserted hereunder and to authorize
    any release of the Escrow Shares and the Dividends to be made with
    respect thereto, on behalf of the Stockholders and their successors.
    All actions to be taken by the Stockholder Representative hereunder
    shall be evidenced by, and taken upon, the written direction of a
    majority thereof.

       (d) The Escrow Agent may rely on the Stockholder Representative as
    the exclusive agent of the Stockholders under this Agreement and shall
    incur no liability to any party with respect to any action taken or
    suffered by it in reliance thereon.

     8. Termination. This Agreement shall terminate upon the distribution by
  the Escrow Agent of all of the Escrow Shares and the Dividends in
  accordance with this Agreement; provided that the provisions of Sections 6
  and 7 shall survive such termination.

     9. Notices. All notices, instructions and other communications given
  hereunder or in connection herewith shall be in writing. Any such notice,
  instruction or communication shall be sent either (i) by registered or
  certified mail, return receipt requested, postage prepaid, or (ii) via a
  reputable nationwide overnight courier service, in each case to the address
  set forth below. Any such notice, instruction or communication shall be
  deemed to have been delivered two business days after it is sent by
  registered or certified mail, return receipt requested, postage prepaid, or
  one business day after it is sent via a reputable nationwide overnight
  courier service.

  by delivering a resignation to the parties to this Escrow Agreement, not
  less than 60 days prior to the date when such resignation shall take
  effect. Parent may appoint a successor Escrow Agent without the consent of
  the Stockholder Representative so long as such successor is a bank with
  assets of at least $500 million, and may appoint any other successor Escrow
  Agent with the consent of the Stockholder Representative, which shall not
  be unreasonably withheld. If, within such notice period,

  of any Escrow Shares then held by the Escrow Agent to such successor, the
  Escrow Agent shall act in accordance with such instructions and promptly
  transfer such
  Escrow Shares to such designated successor. If no successor Escrow Agent is
  named as provided in this Section 10 prior to the date on which the
  resignation of the Escrow Agent is to properly take effect, the Escrow
  Agent may apply to a court of competent jurisdiction for appointment of a
  successor Escrow Agent.

     11. General.

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

   Section 145 of the Delaware General Corporation Law ("DGCL") provides that a
corporation has the power to indemnify its officers, directors, employees and
agents (or persons serving in such positions in another entity at the request
of the corporation) against the expenses, including attorneys' fees, judgments,
fines or settlement amounts actually and reasonably incurred by them in
connection with the defense of any action by reason of being or having been
directors or officers, if such person shall have acted in good faith and in a
manner reasonably believed to be in or not opposed to the best interests of the
corporation (and, with respect to any criminal action, had no reasonable cause
to believe the person's conduct was unlawful), except that, if such action
shall be by or in the right of the corporation, no such indemnification shall
be provided as to any claim, issue or matter as to which such person shall have
been judged to have been liable to the corporation unless and to the extent
that the Court of Chancery of the State of Delaware, or another court in which
the suit was brought, shall determine upon application that, in view of all of
the circumstances of the case, such person is fairly and reasonably entitled to
indemnity.

   As permitted by Section 102 of the DGCL, the registrant's Restated
Certificate of Incorporation provides that no director shall be personally
liable to the registrant or its stockholders for monetary damages for any
breach of fiduciary duty as a director, except for liability (i) for breaches
of the director's duty of loyalty to the registrant or its stockholders, (ii)
for acts or omissions not in good faith or which involve intentional misconduct
or a knowing violation of law, (iii) for the unlawful payment of dividends or
unlawful stock purchases or redemptions under Section 174 of the DGCL, or (iv)
for any transaction from which the director derived an improper personal
benefit.

   The registrant's Restated Certificate of Incorporation further provides that
the registrant must indemnify and hold harmless, to the fullest extent
authorized by the DGCL, as the same exists or may be hereafter amended (but, in
the case of any such amendment, only to the extent that the amendment permits
the registrant to provide broader indemnification rights than the DGCL
permitted the registrant to provide prior to such amendment), each person who
was or is made a party or is threatened to be made a party to or is involved in
any action, suit or proceeding, whether civil, criminal, administrative or
investigative, by reason of the fact that he or she, or a person of whom he or
she is the legal representative, is or was a director or officer of the
registrant or is or was serving (at such time as such person is or was a
director or officer of the registrant) at the request of the registrant as a
director, officer, employee or agent of another entity, including service with
respect to employee benefit plans, whether the basis of such proceeding is
alleged action in an official capacity as a director, officer, employee or
agent or in any other capacity while serving as a director, officer, employee
or agent, against all expense, liability and loss reasonably incurred or
suffered by such indemnitee in connection therewith. This right to
indemnification will continue as to an indemnitee who has ceased to be a
director, officer, employee or agent and will inure to the benefit of the
indemnitee's heirs, executors and administrators. However, except as provided
below with respect to proceedings to enforce rights to indemnification, the
registrant will indemnify any such indemnitee in connection with a proceeding
(or part thereof) initiated by that indemnitee only if the proceeding was
authorized by the registrant's Board of Directors.

   The Restated Certificate of Incorporation provides that the right to
indemnification is a contract right and includes the right to be paid by the
registrant the expenses incurred in defending any such proceeding in advance of
its final disposition. However, if and to the extent that the DGCL requires, an
advancement of expenses incurred by an indemnitee in his or her capacity as a
director or officer (and not in any other capacity in which service was or is
rendered by such indemnitee, including, without limitation, service to an
employee benefit plan) will be made only upon delivery to the registrant of an
undertaking, by or on behalf of such indemnitee, to repay all amounts so
advanced if it shall ultimately be determined by final judicial decision that
such indemnitee is not entitled to be indemnified for such expenses. The
registrant's Restated Certificate of

                                      II-1
<PAGE>

Incorporation also provides that the registrant may, by action of the
registrant's Board of Directors or by action of any person to whom the
registrant's Board of Directors has delegated such authority, provide
indemnification to employees and agents of the registrant with the same scope
and effect as the indemnification of the registrant's officers and directors.
The rights to indemnification and to the advancement of expenses conferred in
the Restated Certificate of Incorporation will not be exclusive of any other
right which any person may have or hereafter acquire under the Restated
Certificate of Incorporation, by-law, agreement, vote of stockholders or
disinterested directors or otherwise.

   Section 145 of the DGCL also provides that a corporation has the power to
purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the corporation (or who was serving at
the request of the corporation in such position at another entity) against any
liability asserted against such person and incurred by such person in any such
capacity, or arising out of such person's status as such, whether or not the
corporation would have the power to indemnify such person against such
liability under the DGCL. The Restated Certificate of Incorporation provides
that the registrant may maintain insurance, at its own expense, to protect
itself and any director, officer, employee or agent of the registrant or
another corporation, partnership, joint venture, trust or other enterprise
against any expense, liability or loss, whether or not the registrant would
have the power to indemnify such person against such expense, liability or loss
under the DGCL. All of the directors and officers of the registrant are covered
by insurance policies maintained and held in effect by the registrant against
liabilities for actions taken in such capacities, including liabilities under
the Securities Act of 1933, as amended, subject to certain exclusions.

Item 22. Undertakings.

   (a) The undersigned registrant hereby undertakes:

     (1) To file, during any period in which offers or sales are being made,
  a post-effective amendment to this registration statement:

       (i) To include any prospectus required by Section 10(a)(3) of the
    Securities Act of 1933;

       (ii) To reflect in the prospectus any facts or events arising after
    the effective date of this registration statement (or the most recent
    post-effective amendment thereof) which, individually or in the
    aggregate, represent a fundamental change in the information set forth
    in this registration statement.

       (iii) To include any material information with respect to the plan
    of distribution not previously disclosed in this registration statement
    or any material change to such information in this registration
    statement.

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

     (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the
  termination of the offering.

   (b) The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to Section 13(a) or Section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in this
registration statement shall be deemed to be a new registration statement
relating to the securities offered herein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

                                      II-3
<PAGE>

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

   (d) The registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (c) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used
in connection with an offering of securities subject to Rule 415, will be filed
as a part of an amendment to the registration statement and will not be used
until such amendment is effective, and that, for purposes of determining any
liability under the Securities Act of 1933, each such post-effective amendment
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

   (e) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that, in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act of 1933 and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

   (f) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Item 4, 10(b), 11 or 13 of this form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of this registration statement through
the date of responding to the request.

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

                                March 24, 2000

Motorola, Inc.
1303 East Algonquin Road
Schaumburg, Illinois 60196

Ladies and Gentlemen:

     I refer to the Registration Statement on Form S-4 (the "Registration
Statement") of Motorola, Inc., a Delaware corporation (the "Company"), filed on
March 24, 2000 with the Securities and Exchange Commission under the Securities
Act of 1993, as amended (the "Securities Act").  The Registration Statement
relates to up to 2,907,862 shares of the Company's Common Stock, $3 par value
per share (including the associated preferred stock purchase rights, the
"Shares"), which are to be issued in connection with the merger (the "Merger")
of CP Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of
the Company ("Merger Sub"), with and into C-Port Corporation, a Delaware
corporation ("C-Port"), pursuant to the Agreement and Plan of Merger dated as of
February 17, 2000 by and among C-Port, the Company and Merger Sub (the "Merger
Agreement").

     On February 29, 2000, the Company declared, subject to approval by its
stockholders, a 3-for-1 stock split in the form of a stock dividend payable on
June 1, 2000 to holders of the Company's Common Stock of record on May 15, 2000.
To the extent that the Merger is completed after May 15, 2000, the Registration
Statement will be deemed to cover, pursuant to Rule 416 under the Securities
Act, 8,723,586 shares of the Company's Common Stock (including the associated
stock purchase rights) to give effect to the stock split, and for purposes of
this opinion letter the term "Shares" shall refer to such higher number covered
by the Registration Statement.

     I have examined and am familiar with (i) the Company's Restated Certificate
of Incorporation, as amended, (ii) the Company's By-Laws, as amended, and (iii)
the corporate proceedings relating to the Registration Statement.  Upon the
basis of the foregoing, and having satisfied myself as to such other matters of
law and fact as I consider relevant for the purposes of this opinion, I advise
you that, in my opinion, upon issuance and delivery of the Shares in accordance
with the Merger Agreement, the Shares will have been validly issued, fully paid
and non-assessable.

     The foregoing opinion is limited to the General Corporation Law of the
State of Delaware.  I express no opinion herein as to any other laws, statutes,
regulations or ordinances.

     I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of my name in the Registration Statement
under the caption "Legal and Tax Matters." In giving this consent, I do not
admit that I am within the category of persons whose consent is required by
Section 7 of the Securities Act.

                                         Very truly yours,

                                         /s/ Donald F. McLellan

    Re:  Agreement and Plan of Merger among Motorola, Inc.,
         CP Acquisition Corp., and C-Port Corporation
         --------------------------------------------

Ladies and Gentlemen:

     This opinion is being delivered to you in connection with the filing of a
registration statement (the "Registration Statement") on Form S-4, which
includes the Proxy Statement and Prospectus relating to the Agreement and Plan
of Merger dated as of February 17, 2000 (the "Merger Agreement"), by and among
Motorola, Inc., a Delaware corporation ("Parent"), CP Acquisition Corp., a
Delaware corporation and wholly owned subsidiary of Parent ("Sub"), and C-Port
Corporation, a Delaware corporation ("Target").  Pursuant to the Merger
Agreement, Sub will merge with and into Target (the "Merger").  Except as
otherwise provided, capitalized terms not defined herein have the meanings set
forth in the Merger Agreement and the exhibits thereto or in the letters
delivered to Hale and Dorr LLP by Parent and Target containing certain
representations of Parent and Target relevant to this opinion (the
"Representation Letters").  All section references, unless otherwise indicated,
are to the United States Internal Revenue Code of 1986, as amended (the "Code").

     In our capacity as counsel to Target in the Merger, and for purposes of
rendering this opinion, we have examined and relied upon the Registration
Statement, the Merger Agreement and the exhibits thereto, including the Escrow
Agreement, the Representation Letters, and such other documents as we considered
relevant to our analysis.  In our examination of documents, we have assumed the
authenticity of original documents, the accuracy of copies, the genuineness of
signatures, and the legal capacity of signatories.

     We have assumed that all parties to the Merger Agreement and to any other
documents examined by us have acted, and will act, in accordance with the terms
of such Merger Agreement and documents and that the Merger will be consummated
at the Effective Time pursuant to the terms and conditions set forth in the
Merger Agreement without the waiver or modification of any such terms and
conditions.  Furthermore, we have assumed that all representations contained in
the Merger Agreement, as well as those representations contained in the
Representation Letters, are, and at the Effective

Time will be, true and complete in all material respects, and that any
representation made in any of the documents referred to herein "to the best of
the knowledge and belief" (or similar qualification) of any person or party is,
and at the Effective Time will be, correct without such qualification. We have
also assumed that as to all matters for which a person or entity has represented
that such person or entity is not a party to, does not have, or is not aware of,
any plan, intention, understanding, or agreement, there is no such plan,
intention, understanding, or agreement. We have not attempted to verify
independently such representations, but in the course of our representation,
nothing has come to our attention that would cause us to question the accuracy
thereof.

     The conclusions expressed herein represent our judgment as to the proper
treatment of certain aspects of the Merger under the income tax laws of the
United States based upon the Code, Treasury Regulations, case law, and rulings
and other pronouncemens of the Internal Revenue Service (the "IRS") as in effect
on the date of this opinion.  No assurances can be given that such laws will not
be amended or otherwise changed prior to the Effective Time, or at any other
time, or that such changes will not affect the conclusions expressed herein.
Nevertheless, we undertake no responsibility to advise you of any developments
after the Effective Time in the application or interpretation of the income tax
laws of the United States.

     Our opinion represents our best judgment of how a court would decide if
presented with the issues addressed herein and is not binding upon either the
IRS or any court.  Thus, no assurances can be given that a position taken in
reliance on our opinion will not be challenged by the IRS or rejected by a
court.

     This opinion addresses only the specific United States federal income tax
consequences of the Merger set forth below, and does not address any other
federal, state, local, or foreign income, estate, gift, transfer, sales, use, or
other tax consequences that may result from the Merger or any other transaction
(including any transaction undertaken in connection with the Merger).  We
express no opinion regarding the tax consequences of the Merger to stockholders
of Target that are subject to special tax rules, and we express no opinion
regarding the tax consequences of the Merger arising in connection with the
ownership of options or warrants for Target stock.

     On the basis of, and subject to, the foregoing, and in reliance upon the
representations and assumptions described above, we are of the opinion that the
discussion under the section "Material Federal Income Tax Consequences of the C-
Port Merger" in the Registration Statement, subject to the limitations and
qualifications described therein, accurately describes the material federal
income tax considerations relevant to Target stockholders receiving Parent
Common Stock in the Merger.

     In rendering this opinion, we have assumed that Winston & Strawn has
delivered, and has not withdrawn, an opinion that is substantially similar to
this one.  No opinion is expressed as to any federal income tax consequence of
the Merger except as specifically set forth herein, and this opinion may not be
relied upon except with respect to the consequences specifically discussed
herein.

CP Acquisition Corp.
1303 East Algonquin Road
Schaumburg, Illinois 60196

Ladies and Gentlemen:

          We have acted as special counsel to Motorola, Inc., a Delaware
corporation ("Parent"), and CP Acquisition Corp., a Delaware corporation and a
wholly owned subsidiary of Parent ("Merger Sub"), in connection with (i) the
Merger (as defined and described in the Agreement and Plan of Merger, dated as
of February 17, 2000 (the "Merger Agreement"), by and among Parent, Merger Sub,
and C-Port Corporation, a Delaware corporation ("Company")), and (ii) the
preparation and filing of the Registration Statement with the Securities and
Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended (the "Securities Act"), on _______ , which includes the Proxy Statement
of Company and the Prospectus of Parent (the "Proxy Statement/Prospectus").
Unless otherwise indicated, each capitalized term used herein has the meaning
ascribed to it in the Merger Agreement.

          In connection with this opinion letter, we have examined the Merger
Agreement, the Proxy Statement/Prospectus, and such other documents and
corporate records as we have deemed necessary or appropriate in order to enable
us to render the opinion set forth below. For purposes of this opinion letter,
we have assumed (i) the validity and accuracy of the documents and corporate
records that we have examined and the facts and representations concerning the
Merger that have come to our attention during our engagement and (ii) that the
Merger has been or will be consummated in the manner described in the Merger
Agreement and the Proxy Statement/Prospectus.

          Subject to the foregoing and the fact that the discussion in the Proxy
Statement/Prospectus under the heading "MERGER - Material Federal Income Tax
Consequences of the C-Port Merger" (the "Discussion") is a summary and does
not purport to discuss all possible United States federal income tax
consequences of the Merger, we are of the opinion that the Discussion states the
material United States federal income tax consequences of the Merger to holders
of Company Capital Stock who surrender such stock in exchange for Parent Common
Stock pursuant to the Merger Agreement. In addition, we express no opinion as to
the United States federal, state, local, foreign or other tax consequences,
other than as set forth in the Discussion. Further,
<PAGE>

there can be no assurances that the opinion expressed herein will be accepted by
the Internal Revenue Service (the "IRS") or, if challenged, by a court. This
opinion letter is delivered in accordance with the requirements of Item
601(b)(8) of Regulation S-K under the Securities Act.

          In rendering our opinion, we have considered the applicable provisions
of the Internal Revenue Code of 1986, as amended, Treasury Department
regulations promulgated thereunder, pertinent judicial authorities, interpretive
rulings of the IRS, and such other authorities as we have considered relevant.
It should be noted that statutes, regulations, judicial decisions, and
administrative interpretations are subject to change at any time, possibly with
retroactive effect. A change in the authorities or the accuracy or completeness
of any of the information, documents, corporate records, covenants, statements,
representations or assumptions on which our opinion is based could affect our
conclusions. The opinion set forth herein is expressed as of the date hereof,
and we are under no obligation to supplement or revise our opinion to reflect
any changes (including changes that have retroactive effect) (i) in applicable
law or (ii) in any information, document, corporate record, covenant, statement,
representation, or assumption stated herein that becomes untrue or incorrect.

          This opinion letter is furnished to you solely for use in connection
with the Merger, as described in the Merger Agreement and the Proxy
Statement/Prospectus, and is not to be used, circulated, quoted, or otherwise
referred to for any other purpose without our express written permission. In
accordance with the requirements of Item 601(b)(23) of Regulation S-K under the
Securities Act, we hereby consent to the filing of this opinion as an exhibit to
the Proxy Statement/Prospectus and to the reference to our firm name under the
headings "MERGER -Material Federal Income Tax Consequences of the C-Port
Merger", "THE MERGER AGREEMENT - Conditions", and "LEGAL AND TAX MATTERS." In
giving such consent, we do not thereby admit that we are in the category of
persons whose consent is required under Section 7 of the Securities Act or the
rules and regulations of the Commission thereunder.

                              Very truly yours,

                              Winston & Strawn
