                                PROXY STATEMENT
 
     The Board of Directors of ViaSat, Inc. is soliciting the enclosed proxy for
use at the annual meeting of stockholders to be held on September 26, 2000, at
8:30 a.m., at the corporate offices of ViaSat at 6155 El Camino Real, Carlsbad,
California 92009.
 
            GENERAL INFORMATION ABOUT THE ANNUAL MEETING AND VOTING
 
WHY DID YOU SEND ME THIS PROXY STATEMENT?
 
     We sent you this proxy statement and the enclosed proxy card because
ViaSat's Board of Directors is soliciting your proxy to vote at the 2000 annual
meeting of stockholders. This proxy statement summarizes the information you
need to know to vote at the annual meeting. All stockholders who find it
convenient to do so are cordially invited to attend the annual meeting in
person. However, you do not need to attend the meeting to vote your shares.
Instead, you may simply complete, sign and return the enclosed proxy card.
 
     On or about August 14, 2000, we began sending this proxy statement, the
attached notice of annual meeting and the enclosed proxy card to all
stockholders entitled to vote. Only stockholders who owned ViaSat common stock
at the close of business on July 28, 2000 are entitled to vote at the annual
meeting. On this record date, there were 10,896,726 shares of ViaSat common
stock outstanding. Common stock is our only class of stock entitled to vote. We
are also sending along with this proxy statement our 2000 Annual Report, which
includes our financial statements.
 
WHAT AM I VOTING ON?
 
     - The election of two directors to serve a three-year term. The present
       Board of Directors of ViaSat has nominated and recommends for election as
       directors the following two persons:
 
          ROBERT W. JOHNSON
          WILLIAM A. OWENS
 
     - To approve an amendment to The 1996 Equity Participation Plan of ViaSat,
       Inc. to increase the number of authorized shares by 1,800,000 shares to
       3,050,000 shares.
 
     - To approve an amendment to ViaSat's Certificate of Incorporation to
       increase the authorized number of shares of common stock from 25,000,000
       shares to 100,000,000 shares.
 
HOW MANY VOTES DO I HAVE?
 
     Each share of ViaSat common stock that you own entitles you to one vote.
 
HOW DO I VOTE BY PROXY?
 
     Whether you plan to attend the annual meeting or not, we urge you to
complete, sign and date the enclosed proxy card and to return it promptly in the
envelope provided. Returning the proxy card will not affect your right to attend
or vote at the meeting.
 
                                        1

<PAGE>   5
 
     If you properly complete your proxy card and send it to us in time to vote,
your "proxy" (i.e. one of the individuals named on your proxy card) will vote
your shares as you have directed. If you sign the proxy card but do not make
specific choices, your proxy will vote your shares as recommended by the Board
of Directors as follows:
 
     - "FOR" the election of the two nominees for director.
 
     - "FOR" the proposal to approve an amendment to the Equity Participation
       Plan to increase the number of authorized shares under by 1,800,000
       shares.
 
     - "FOR" the proposal to approve an amendment to ViaSat's Certificate of
       Incorporation to increase the authorized number of shares of common stock
       from 25,000,000 shares to 100,000,000 shares.
 
     If any other matter is presented at the annual meeting, your proxy will
vote in accordance with his best judgment. As of the date of this proxy
statement, we knew of no matters that needed to be acted on at the meeting,
other than those discussed in this proxy statement.
 
MAY I REVOKE MY PROXY?
 
     If you give us your proxy, you may revoke it at any time before it is
exercised. You may revoke your proxy in any one of the three following ways:
 
     - You may send in another signed proxy with a later date,
 
     - You may notify ViaSat's Secretary, Gregory D. Monahan, in writing before
       the annual meeting that you have revoked your proxy, or
 
     - You may notify ViaSat's Secretary in writing before the annual meeting
       and vote in person at the meeting.
 
HOW DO I VOTE IN PERSON?
 
     If you plan to attend the annual meeting and vote in person, we will give
you a ballot when you arrive. However, if your shares are held in the name of
your broker, bank or other nominee, you must bring an account statement or
letter from the nominee indicating that you were the beneficial owner of the
shares on July 28, 2000, the record date for voting.
 
WHAT CONSTITUTES A QUORUM?
 
     The presence at the annual meeting, in person or by proxy, of a majority of
our outstanding common stock, or approximately 5,448,363 shares, constitutes a
quorum at the meeting, permitting us to conduct our business. Proxies that are
returned to us that reflect abstentions or include "broker non-votes" will be
treated as present and entitled to vote for purposes of determining the presence
of a quorum.
 
WHAT VOTE IS REQUIRED TO APPROVE EACH PROPOSAL?

Proposal 1: Election of Directors               The two nominees for director who receive
                                                the most votes will be elected.
Proposal 2: Approval of Amendment to the        The affirmative vote of a majority of the
Equity Participation Plan                       votes cast at the annual meeting is
                                                required.

WHAT IS THE EFFECT OF ABSTENTIONS AND BROKER NON-VOTES?
 
     Shares represented by proxies that reflect abstentions or include "broker
non-votes" will be treated as present and entitled to vote for purposes of
determining the presence of a quorum. Abstentions will be counted towards the
tabulation of votes cast on proposals presented to the stockholders and will
have the same effect as negative votes. Broker non-votes are counted towards a
quorum but are not counted for any purpose in determining whether a proposal has
been approved. However, broker non-votes can have the same effect as negative
votes on proposals requiring the affirmative vote of a majority of the
outstanding shares of common stock (such as Proposal 3).
 
WHAT ARE THE COSTS OF SOLICITING THESE PROXIES?
 
     We will pay all of the costs of soliciting these proxies. Our directors and
employees may solicit proxies in person or by telephone, fax or email. We will
pay these employees and directors no additional compensation for these services.
We will ask banks, brokers and other institutions, nominees and fiduciaries to
forward these proxy materials to their principals and to obtain authority to
execute proxies. We will then reimburse them for their expenses.
 
HOW DO I OBTAIN AN ANNUAL REPORT ON FORM 10-K?
 
     If you would like a copy of our Annual Report on Form 10-K for the fiscal
year ended March 31, 2000 that we filed with the Securities and Exchange
Commission, we will send you one without charge. Please write to:

                                  PROPOSAL 2:
 
             APPROVAL OF AMENDMENT TO THE EQUITY PARTICIPATION PLAN
 
     At the annual meeting, you will be asked to consider and vote upon a
proposal to approve an amendment to the Equity Participation Plan to increase
the number of authorized shares of common stock by 1,800,000 shares to 3,050,000
shares. The Equity Participation Plan was initially adopted by ViaSat's Board of
Directors and stockholders in November 1996.
 
DESCRIPTION OF THE EQUITY PARTICIPATION PLAN
 
     General Nature and Purpose. The Equity Participation Plan was adopted (1)
to further our growth, development and financial success by providing additional
incentives to some of our key employees who have been or will be given
responsibility for the management or administration of our business affairs, by
assisting them to become owners of our capital stock and thus to benefit
directly from our growth, development and financial success, and (2) to enable
us to retain the services of the type of professional, technical and managerial
employees considered essential to our long-range success, by providing and
offering them the opportunity to become owners of our capital stock. The Equity
Participation Plan provides for the grant to our executive officers, other key
employees, consultants and non-employee directors of a broad variety of stock-
based compensation alternatives such as nonqualified stock options, incentive
stock options, restricted stock and performance awards.
 
     Administration. The Equity Participation Plan is administered by the
Compensation Committee of the Board of Directors. In addition to administering
the Equity Participation Plan, the Compensation Committee is also authorized to
adopt, amend and rescind rules relating to the administration of the Equity
Participation Plan.
 
     Eligibility. Any employee or consultant selected by the Compensation
Committee is eligible to receive options under the Equity Participation Plan.
The Compensation Committee, in its absolute discretion, will determine (1) among
the eligible participants the individuals to whom options, restricted stock
purchase rights and performance awards are to be granted, (2) the number of
shares to be granted, and (3) the terms and conditions of the grants.
 
     Grant of Options. The Compensation Committee will from time to time, in its
absolute discretion, determine (1) the number of shares to be subject to options
granted to selected employees and consultants, (2) whether the options are to be
incentive stock options or non-qualified stock options, and (3) the terms and
conditions of the options, in a manner consistent with the Equity Participation
Plan.
 
                                        6

<PAGE>   10
 
     During the term of the Equity Participation Plan, a person who is initially
elected to the Board of Directors and who is an independent director at that
time is automatically granted an option to purchase 7,500 shares of common stock
and an option to purchase 4,000 shares of common stock on the date of each
subsequent annual meeting of stockholders.
 
     Purchase Price of Optioned Shares. The price per share of the shares
subject to each option is set by the Compensation Committee. However, the price
per share cannot be less than the par value of a share of common stock, unless
otherwise permitted by applicable state law. In the case of incentive stock
options and options intended to qualify as performance-based compensation the
price cannot be less than 100% of the fair market value of a share of common
stock on the date the option is granted. In the case of incentive stock options
granted to an individual then owning more than 10% of the total combined voting
power of all classes of stock of ViaSat or any subsidiary or parent corporation
of ViaSat the price cannot be less than 110% of the fair market value of a share
of common stock on the date the option is granted.
 
     Terms of Options. Options granted under the Equity Participation Plan may
not be exercised more than ten years after the date of grant, although the
Compensation Committee may grant options having shorter terms. The term cannot
exceed five years in the case of incentive stock options granted to an
individual then owning more than 10% of the total combined voting power of all
classes of stock of ViaSat. Except as limited by the Equity Participation Plan
or applicable law, the Compensation Committee may extend the term of any
outstanding option in connection with any termination of employment or
termination of consultancy of the optionee, or amend any other term or condition
of the option relating to a termination.
 
     Exercise of Options. Upon the exercise of an option under the Equity
Participation Plan, the optionee must make full cash payment to the Secretary of
ViaSat for the shares with respect to which the option, or portion of the
option, is exercised. However, the Compensation Committee may in its discretion
allow various forms of payment which are described in the Equity Participation
Plan.
 
     Other Stock Awards. The Equity Participation Plan allows for various other
awards including restricted stock, performance awards, dividend equivalents,
deferred stock, stock payments, and stock appreciation rights. There have not
been any of these awards granted since the inception of the Equity Participation
Plan.
 
     Amendment of the Plan. The Equity Participation Plan may be wholly or
partially amended or otherwise modified, suspended or terminated at any time or
from time to time by the Board of Directors or the Compensation Committee.
However, without approval of the stockholders of ViaSat, the Equity
Participation Plan may not be amended to (1) increase the maximum number of
shares issuable upon exercise of options granted under the Equity Participation
Plan and (2) no action of the Board of Directors or the Compensation Committee
may be taken that would otherwise require stockholder approval as a matter of
applicable law, regulation or rule.
 
     Grants in 1999 and 2000. Options to purchase 324,000 shares of common stock
were granted in fiscal year 1999 and 425,800 shares of common stock were granted
in fiscal year 2000 under the Equity Participation Plan. See "Executive
Compensation and Other Information" below for more information regarding the
options granted to some of our executive officers under the Equity Participation
Plan in 1999 and 2000.
 
PROPOSED AMENDMENT TO THE EQUITY PARTICIPATION PLAN
 
     A total of 1,250,000 shares of common stock are currently reserved for
issuance under the Equity Participation Plan. The Board of Directors recommends
an amendment to the Equity Participation Plan to increase the number of shares
available for issuance under the Equity Participation Plan by 1,800,000 shares
to 3,050,000 shares.
 
     As of July 28, 2000, options to purchase an aggregate of 1,182,576 shares
of common stock had been issued under the Equity Participation Plan.
Accordingly, only 67,424 shares of common stock were available for the issuance
of new options.
 
     ViaSat has been experiencing a period of significant growth in hiring and
ViaSat's management and Board of Directors believe that stock options are a key
aspect of ViaSat's ability to attract qualified
 
                                        7

<PAGE>   11
 
engineering, technical and other personnel in the face of an increasingly
competitive hiring environment. The Board of Directors approved an increase in
the number of shares reserved for issuance under the Equity Participation Plan
to ensure that ViaSat is able to continue to grant stock options to employees
and consultants at levels determined appropriate by the Board of Directors and
the Compensation Committee. In the event that this Proposal 2 is not approved by
the stockholders, and as a consequence ViaSat is unable to continue to grant
options at competitive levels, ViaSat's management believes that it will
negatively affect ViaSat's ability to manage future growth that may require the
hiring of additional highly qualified personnel.
 
     The proposal to amend the Equity Participation Plan to increase the number
of shares authorized for issuance under the Equity Participation Plan will only
become effective, and is conditioned upon, stockholder approval of the amendment
to ViaSat's Certificate of Incorporation to increase the authorized number of
shares of common stock from 25,000,000 to 100,000,000 described below.
 
FEDERAL TAX CONSEQUENCES
 
     The income tax consequences of options granted under the Equity
Participation Plan under current federal law are summarized below. The
discussion is intended to provide only general information. Federal alternative
minimum tax and employment tax consequences and state, local and foreign tax
consequences are not discussed.
 
     The optionee will not recognize ordinary income by reason of the grant or
exercise of an incentive stock option. If an optionee holds stock acquired
through exercise of an incentive stock option for at least two years from the
date on which the option is granted and at least one year from the date on which
the stock is transferred to the optionee upon exercise of the option, any gain
or loss upon sale or other disposition of the stock will be capital gain or
loss. ViaSat will not be entitled to a deduction if the optionee holds the stock
for these holding periods. Generally, if the optionee sells or disposes of the
stock before the expiration of either of these holding periods (a "disqualifying
disposition"), at the time of sale or disposition, the optionee will recognize
ordinary income equal to the lesser of (a) the excess of the stock's fair market
value on the date of exercise over the aggregate exercise price, or (b) the
optionee's actual gain, if any, on the sale or disposition. The optionee's
additional gain, if any, upon the disqualifying disposition will be capital
gain.
 
     To the extent the optionee recognizes ordinary income by reason of a
disqualifying disposition, ViaSat generally will be entitled (subject to the
requirement of reasonableness, Internal Revenue Code Section 162(m) and the
satisfaction of a tax reporting obligation) to a corresponding business expense
deduction in the tax year in which the disqualifying disposition occurs.
 
     The optionee will not recognize ordinary income by reason of the grant of a
non-qualified stock option. Upon exercise of a non-qualified stock option, the
optionee will recognize ordinary income equal to the excess of the stock's fair
market value on the date of exercise over the aggregate exercise price paid.
Generally, with respect to employees, ViaSat is required to withhold taxes in an
amount based on the ordinary income recognized. Subject to the requirement of
reasonableness, Internal Revenue Code Section 162(m) and the satisfaction of a
tax-reporting obligation, ViaSat generally will be entitled to a business
expense deduction equal to the taxable ordinary income realized by the optionee.
Upon sale or disposition of the stock, the optionee will recognize any gain or
loss as capital gain or loss.
 
     Internal Revenue Code Section 162(m) denies a deduction to any publicly
held corporation for compensation paid to certain executive officers in a
taxable year to the extent that compensation exceeds $1,000,000 for the
executive officer. Compensation attributable to stock options, alone or when
combined with all other types of compensation received by the executive officer
from ViaSat, may cause this limitation to be exceeded in any particular year.
 
     Some kinds of compensation, including qualified "performance-based
compensation," are disregarded for purposes of the deduction limitation. In
accordance with applicable Treasury regulations issued under Section 162(m),
compensation attributable to stock options will qualify as performance-based
compensation, provided that: either (1) (a) the option plan contains a
per-employee limitation on the number of shares for which options may be granted
during a specified period, (b) the per-employee limitation is approved by the
 
                                        8

<PAGE>   12
 
stockholders, (c) the option is granted by a compensation committee comprised
solely of "outside directors" (as defined in Section 162(m)) and (d) the
exercise price of the option is no less than the fair market value of the stock
on the date of grant; or (2) the option is granted by a compensation committee
comprised solely of "outside directors" and is granted (or exercisable) only
upon the achievement of an objective performance goal established by the
compensation committee while the outcome is substantially uncertain and approved
by the stockholders.
 
     The foregoing discussion is intended to be a general summary only of the
federal income tax aspects of options granted under the Equity Participation
Plan; tax consequences may vary depending on the particular circumstances at
hand. In addition, administrative and judicial interpretations of the
application of the federal income tax laws are subject to change.
 
PLAN BENEFITS
 
     The following table presents information with respect to options granted
under the Equity Participation Plan as of July 28, 2000, to (1) ViaSat's Chief
Executive Officer and its four other most highly compensated executive officers
at March 31, 2000 (collectively, the "Named Executive Officers"), (2) all
executive officers as a group, (3) all non-executive officer employees as a
group, and (4) all non-employee directors as a group.

                                  PROPOSAL 3:
 
             APPROVAL OF AMENDMENT TO CERTIFICATE OF INCORPORATION
                 TO AUTHORIZE ADDITIONAL SHARES OF COMMON STOCK
 
     At the annual meeting, you will be asked to consider and vote upon a
proposal to approve an amendment to ViaSat's Certificate of Incorporation to
increase ViaSat's authorized number of shares of common stock from 25,000,000
shares to 100,000,000 shares.
 
PRINCIPAL EFFECTS OF THE AMENDMENT
 
     The additional common stock to be authorized by adoption of the amendment
would have rights identical to the currently outstanding common stock. Adoption
of the proposed amendment and issuance of the common stock would not affect the
rights of the holders of currently outstanding common stock of ViaSat, except
for effects incidental to increasing the number of shares of the common stock
outstanding, such as dilution of the earnings per share and voting rights of
current holders of common stock. If the amendment is adopted, it will become
effective upon filing of a Certificate of Amendment of ViaSat's Certificate of
Incorporation with the Secretary of State of the State of Delaware.
 
     If adopted, the amendment would cause the first paragraph of Article Fourth
of ViaSat's Certificate of Incorporation to read as follows:
 
     "FOURTH: The Corporation is authorized to issue two classes of shares of
     capital stock to be designated respectively, Preferred Stock and Common
     Stock. The total number of shares which the Corporation is authorized to
     issue is one hundred five million (105,000). Five million (5,000,000)
     shares shall be Preferred Stock, of which three million two hundred
     twenty-five thousand (3,225,000) are hereby designated Series A Convertible
     Preferred Stock ("Series A Preferred Stock") and one hundred million
     (100,000,000) shares shall be Common Stock. The Preferred Stock and Common
     Stock shall each have a par value of $.0001 per share."
 
     In addition to the 10,896,726 shares of common stock outstanding at July
28, 2000, the Board of Directors has reserved 405,402 shares for issuance upon
exercise of options and rights granted under ViaSat's stock option and stock
purchase plans, and 50,000 shares of common stock which may be issued upon
exercise of warrants.
 
REASONS FOR THE AMENDMENT
 
     Other than in connection with ViaSat's equity plans, the Board of Directors
has no agreements or commitments to issue additional shares of common stock for
any purpose. However, it desires to have these additional 75,000,000 shares
available to provide additional flexibility to use its capital stock for
business and financial purposes in the future. The additional shares may be
used, without further stockholder approval, for various purposes including,
without limitation, raising capital, providing equity incentives to employees,
officers or directors, establishing strategic relationships with other companies
and expanding ViaSat's business or product lines through the acquisition of
other businesses or products.
 
     From time to time ViaSat considers strategic transactions and alternatives
with the goal of maximizing stockholder value. For example, in April 2000 ViaSat
completed the acquisition of the satellite networking division of
Scientific-Atlanta, Inc. ViaSat will continue to evaluate additional potential
strategic transactions and alternatives which it believes may enhance
stockholder value. These additional potential transactions may include a variety
of different structures, including spin-offs, strategic partnerships, joint
ventures, restructurings, divestitures and business combinations.
 
     The additional shares of common stock that would become available for
issuance if the proposal were adopted could also be used by ViaSat to oppose a
hostile takeover attempt or delay or prevent changes in control or management of
ViaSat. For example, without further stockholder approval, the Board of
Directors could adopt a "poison pill" which would, under some circumstances
related to an acquisition of shares not approved by the Board of Directors, give
some holders the right to acquire additional shares of common stock
 
                                       10

<PAGE>   14
 
at a low price, or the Board could strategically sell shares of common stock in
a private transaction to purchasers who would oppose a takeover or favor the
current Board of Directors. Although this proposal to increase the authorized
common stock has been prompted by business and financial considerations and not
by the threat of any hostile takeover attempt (nor is the Board of Directors
currently aware of any attempts directed at ViaSat), nevertheless, stockholders
should be aware that approval of this proposal could facilitate future efforts
by ViaSat to deter or prevent changes in control of ViaSat, including
transactions in which the stockholders might otherwise receive a premium for
their shares over then current market prices.
 
VOTED REQUIRED; RECOMMENDATION OF THE BOARD OF DIRECTORS
 
     The affirmative vote of the holders of a majority of the outstanding shares
of the common stock, will be required to approve this proposal to amend ViaSat's
Certificate of Incorporation. As a result, abstentions and broker non-votes will
have the same effect as negative votes.
 
     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE
FOR THE AMENDMENT TO VIASAT'S CERTIFICATE OF INCORPORATION. PROXIES SOLICITED BY
THE BOARD OF DIRECTORS WILL BE SO VOTED UNLESS STOCKHOLDERS SPECIFY OTHERWISE ON
THEIR PROXY CARDS.

COMPENSATION PLANS
 
     401(k) Plan. We have established a tax-qualified employee savings and
retirement plan effective January 1990 covering all employees who have been
employed by us for at least 90 days and who are at least 21 years of age. Under
the 401(k) Plan, our employees may elect to reduce their current compensation by
not less than 1.0% nor more than 15.0% of eligible compensation and have the
amount of the reduction contributed to the 401(k) Plan. The 401(k) Plan permits,
but does not require, additional cash contributions to the 401(k) Plan by us.
The trustee under the 401(k) Plan invests the assets of the 401(k) Plan in
designated investment options. The 401(k) Plan is intended to qualify under
Section 401 of the Internal Revenue Code so that contributions to the 401(k)
Plan, and income earned on plan contributions, are not
 
                                       15

<PAGE>   19
 
taxable to our employees until withdrawn from the 401(k) Plan, and so that
contributions by us are deductible by us when made for income tax purposes.
 
     Employee Stock Purchase Plan. We have established the ViaSat, Inc. Employee
Stock Purchase Plan to assist our employees in acquiring a stock ownership
interest in our company and to encourage them to remain in our employment. The
Purchase Plan is intended to qualify under Section 423 of the Internal Revenue
Code. The Purchase Plan permits our eligible employees to purchase our common
stock at a discount through payroll deductions during specified six-month
offering periods. The Purchase Plan is administered by the Compensation
Committee. Currently, a maximum of 500,000 shares of common stock are authorized
for issuance under the Purchase Plan. As of July 28, 2000, an aggregate of
162,022 shares of common stock at prices ranging from $7.65 to $ 42.40 were
issued under the Purchase Plan.
 
     1993 Stock Option Plan. In 1993, we adopted the ViaSat, Inc. 1993 Stock
Option Plan to enable our key employees, consultants and non-employee directors
to acquire a proprietary interest in our company, and to create in such persons
an increased interest in and a greater concern for the welfare of our company.
The 1993 Stock Option Plan provided for aggregate option grants of up to 733,500
shares. As of July 28, 2000, options to purchase an aggregate of 57,433 shares
of common stock at prices ranging from $1.36 to $4.50 were outstanding under the
1993 Stock Option Plan. No additional grants will be made under the 1993 Stock
Option Plan.
 
     1996 Equity Participation Plan. In November, 1996 we adopted The 1996
Equity Participation Plan of ViaSat, Inc. to update and replace the 1993 Stock
Option Plan. The Equity Participation Plan provides for the grant to our
executive officers, other key employees, consultants and non-employee directors
of a broad variety of stock-based compensation alternatives such as nonqualified
stock options, incentive stock options, restricted stock and performance awards.
The Equity Participation Plan provides for aggregate award grants of up to
1,250,000 shares. If Proposal 2 above is approved, the shares of common stock
authorized for issuance under the Equity Participation Plan will be increased by
1,800,000 shares to 3,050,000 shares. As of July 28, 2000, options to purchase
an aggregate of 1,091,693 shares of common stock at prices ranging from $7.38 to
$87.63 were outstanding under the Equity Participation Plan.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     During fiscal year 2000, the Compensation Committee was comprised of
Messrs. Nash and Bunker. No interlocking relationship exists between any member
of the Compensation Committee and any member of any other company's board of
directors or compensation committee.
 
COMMITTEE REPORT ON EXECUTIVE COMPENSATION
 
     The Compensation Committee is responsible for administering our
compensation policies and practices and approves all elements of compensation
for our executive officers. The Compensation Committee reports regularly to the
Board of Directors on its activities. In general, the compensation policies
adopted by the Compensation Committee are designed to provide competitive levels
of compensation to:
 
     - attract and retain executives capable of leading us to meet our business
       objectives and
 
     - motivate our executives to enhance long-term stockholder value.
 
     EXECUTIVE OFFICER COMPENSATION
 
     Our executive compensation program is comprised of base salary, annual cash
incentive bonus and long-term incentive compensation in the form of stock option
grants at current market prices.
 
     Our compensation program for executive officers is designed to provide a
total compensation level (including both annual and long-term incentives) that
is competitive with surveyed companies. For executive officers recently
recruited by us, annual compensation rates and long-term incentive awards
reflect amounts necessary to attract them to our company. The compensation
program is benchmarked by using surveys of companies in the high technology
industry with similar revenues and/or prospects. These companies, which
 
                                       16

<PAGE>   20
 
are representative of the firms we compete with for executive talent and have
jobs similar to those at our company in magnitude, complexity and scope of
responsibility, form the basis for the survey group used by the Compensation
Committee.
 
     COMPONENTS OF EXECUTIVE COMPENSATION
 
     - Base salary is established by the Compensation Committee based on an
       executive's job responsibilities, level of experience, individual
       performance and contribution to our company, and information obtained
       from surveys. The Compensation Committee believes that the executives'
       base salaries are at competitive levels relative to the various markets
       from which our company attracts its executive talent.
 
     - Annual cash incentive bonus is established by the Compensation Committee
       at the end of the fiscal year and is based on our company's performance,
       individual performance, and compensation surveys. Bonuses awarded in
       prior years are also taken into consideration. The bonuses are at risk
       and are not arithmetically derived using a bonus formula.
 
     - Long-term incentives include awards of stock options, restricted stock,
       and performance awards. The objective for the awards is to align closely
       executive interests with the longer term interests of stockholders. These
       awards, which are at risk and dependent on the creation of incremental
       stockholder value or the attainment of cumulative financial targets over
       several years, represent a significant portion of the total compensation
       opportunity provided for the executive officers. Award sizes are based on
       individual performance, level of responsibility, the individual's
       potential to make significant contributions to our company, and award
       levels at other companies in the survey group. Long-term incentives
       granted in prior years are also taken into consideration. For fiscal year
       2000, the Compensation Committee determined that the only form of
       long-term incentive awards would be stock options. There were no
       restricted stock or performance awards granted during fiscal year 2000.
 
     COMPENSATION FOR THE CHAIRMAN AND CHIEF EXECUTIVE OFFICER
 
     Mr. Dankberg, a founder of ViaSat, has led ViaSat to another successful
year in fiscal year 2000. ViaSat's fiscal year 2000 achievements in revenue
growth, order backlog, product development and shipments were consistent with
ViaSat's objectives. Additionally, ViaSat accomplished major strategic
achievements in fiscal year 2000, including the acquisition of a commercial
satellite networking division from Scientific-Atlanta, Inc. Under Mr. Dankberg's
direction, ViaSat has achieved fourteen consecutive years of internally
generated revenue growth and thirteen consecutive years of profitability, and is
well positioned to benefit from its successes in developing and deploying
products that utilize Demand Assigned Multiple Access satellite networking
technology. During fiscal year 2000, Mr. Dankberg earned a base salary of
$265,400. In light of the leadership he demonstrated during the year, in July
1999, the Compensation Committee granted Mr. Dankberg a stock option to purchase
15,000 shares of common stock at $16.13 per share (110% of the fair market value
at the time of grant), and the Compensation Committee determined that Mr.
Dankberg should receive a $60,000 bonus.
 
     DEDUCTIBILITY OF COMPENSATION IN EXCESS OF $1 MILLION PER YEAR
 
     Section 162(m) of the Internal Revenue Code, enacted in 1993, generally
disallows a tax deduction to public companies for compensation in excess of $1
million paid to a company's Chief Executive Officer and any of its four other
most highly compensated executive officers. Qualifying performance-based
compensation is not subject to the deduction limit if specific requirements are
met. For 2000 and 2001, we do not anticipate that there will be nondeductible
compensation for the positions in question. The Compensation Committee plans to
continue to review the matter for 2001 and future years in order to determine
the extent of possible modification to our compensation arrangements.

                   RELATIONSHIP WITH INDEPENDENT ACCOUNTANTS
 
     Our financial statements for the fiscal year ended March 31, 2000 have been
examined by PricewaterhouseCoopers LLP. Representatives of
PricewaterhouseCoopers LLP are expected to be available at the annual meeting to
respond to appropriate questions and to make a statement if they desire to do
so. We will select independent accountants for the current year sometime after
the annual meeting.
 
                            SECTION 16(A) REPORTING
 
     Under Section 16(a) of the Securities Exchange Act of 1934, as amended,
directors, executive officers and beneficial owners of 10% or more of the common
stock ("Reporting Persons") are required to report to the Securities and
Exchange Commission on a timely basis the initiation of their status as a
Reporting Person and any changes with respect to their beneficial ownership of
the common stock. Based solely on our review of the forms received by it, or
written representations from the Reporting Persons that these forms were not
required, we have determined that no Reporting Persons known to us were
delinquent with respect to his or her reporting obligations as set forth in
Section 16(a) of the Exchange Act.
 
               STOCKHOLDER PROPOSALS FOR THE 2001 ANNUAL MEETING
 
     Any proposal of a stockholder of ViaSat intended to be presented at the
next annual meeting of stockholders must be received by the Secretary of ViaSat
not later than April 17, 2001 to be considered for inclusion in the our proxy
statement and form of proxy relating to that meeting. In addition, if we have
not received notice by July 3, 2001 of any matter a stockholder intends to
propose for a vote at the next annual meeting of stockholders, then a proxy
solicited by the Board of Directors may be voted on the matter in the discretion
of the proxy holder, without discussion of the matter in the proxy statement
soliciting the proxy and without the matter appearing as a separate item on the
proxy card.
 
                                 OTHER MATTERS
 
     We do not know of any business other than that described in this proxy
statement that will be presented for consideration or action by the stockholders
at the annual meeting. If, however, any other business is properly brought
before the meeting, shares represented by proxies will be voted in accordance
with the best judgment of the persons named in the proxies or their substitutes.
 
          ALL STOCKHOLDERS ARE URGED TO COMPLETE, SIGN AND RETURN THE
           ACCOMPANYING ENDORSED PROXY CARD IN THE ENCLOSED ENVELOPE.

other financial or actuarial personnel employed or retained by the Company. The
Committee may meet with the outside auditor in separate executive sessions to
discuss any matters that the Committee believes should be addressed privately,
without management's presence. The Committee may likewise meet privately with
management, as it deems appropriate.
 
     5. The Committee may, in its discretion, utilize the services of the
Company's regular corporate legal counsel with respect to legal matters or, at
its discretion, retain separate legal counsel if it determines that such counsel
is necessary or appropriate under the circumstances.
 
RESPONSIBILITIES
 
  Independent Auditor
 
     1. The Committee shall review, select and recommend the appointment of the
outside auditor for approval by the Board to audit the Company's financial
statements.
 
     2. The Committee shall approve the fees to be paid to the outside auditor.
 
     3. The Committee shall periodically evaluate the performance of the outside
auditor and, if necessary, recommend that the Board replace the outside auditor.
 
     4. The Committee shall receive from the outside auditor on a periodic basis
(but at least annually) a formal written statement delineating all relationships
between the outside auditor and the Company. The
                                       A-1

<PAGE>   24
 
Committee shall actively engage in a dialogue with the outside auditor with
respect to any disclosed relationships or services that, in the view of the
Committee, may impact the objectivity and independence of the outside auditor.
If the Committee determines that further inquiry is advisable, the Committee

management of the Company at a time early in the process of the annual audit to
review the scope of the audit for the current year and the audit procedures to
be utilized.
 
     2. The Committee shall meet with the outside auditor and management prior
to the public release of the financial results of operations for the subject
year under audit, and discuss with the outside auditor any matters within the
scope of the pending audit that have not yet been completed.
 
     3. The Committee shall receive the completed audited financial statements
for the year under audit, as soon as practicable.
 
     4. The Committee shall review and discuss the audited financial statements
with the management of the Company.
 
     5. The Committee shall discuss with the independent auditors the matters
required to be discussed by SAS 61, including, among others, (i) methods used to
account for any significant unusual transactions reflected in the audited
financial statements; (ii) the effect of significant accounting policies in any
controversial or emerging areas for which there was a lack of authoritative
guidance or consensus to be followed by the outside auditor; (iii) the process
used by management in formulating particularly sensitive accounting estimates
and the basis for the auditor's conclusions regarding the reasonableness of
those estimates; and (iv) any disagreements with management over the application
of accounting principles, the basis for management's accounting estimates or the
disclosures in the financial statements.
 
     6. The Committee shall, based on the discussions referenced in paragraphs 4
and 5 above, and based on the disclosures received from the outside auditor
regarding its independence and discussions with the auditor regarding such
independence (see paragraph 4 above), recommend to the Board whether the audited
financial statements should be included in the Company's Annual Report on Form
10-K for the fiscal year subject to the audit.
 
  Quarterly Review
 
     The outside auditor is required to conduct an interim financial review
prior to the Company's filings of its Form 10-Q (preferably prior to any public
announcement of the earnings). The Committee will review and discuss with
management and the outside auditor, in person at a meeting, or by telephone
conference call, the results of the quarterly review including such matters as
significant adjustments, management judgments, accounting estimates, significant
new accounting policies and disagreements with management. The Chair may
represent the entire Committee for purposes of this review.
 
  Internal Controls
 
     1. The Committee shall review with the outside auditor and financial and
accounting personnel, at least annually, the adequacy and effectiveness of the
accounting and financial controls of the Company, and elicit any recommendations
for improvement of such internal control procedures, in particular in areas
where new or more detailed controls or procedures are desirable.
 
     2. The Committee shall review with the outside auditors and with management
any matters brought to the attention of management and the Committee by the
outside auditors, as a result of their annual audit. The Committee shall allow
management adequate time to prepare responses to any such matters raised by the
outside auditors.

                                  ATTACHMENT I
 
     The following extracts from the rules of The Nasdaq Stock Market, dealing
with qualifications required and composition requirements for the Audit
Committee, are included to provide guidance to the Board of Directors in
ensuring that the members it appoints to the Audit Committee meet requirements.
They are current as of June 14, 2000.
 
RULE 4200. DEFINITIONS
 
     (15) "Independent director" means a person other than an officer or
employee of the company or its subsidiaries or any other individual having a
relationship which, in the opinion of the company's board of directors, would
interfere with the exercise of independent judgment in carrying out the
responsibilities of a director. The following persons shall not be considered
independent:
 
          (a) a director who is employed by the corporation or any of its
     affiliates for the current year or any of the past three years;
 
          (b) a director who accepts any compensation from the corporation or
     any of its affiliates in excess of $60,000 during the previous fiscal year,
     other than compensation for board service, benefits under a tax-qualified
     retirement plan, or non-discretionary compensation;
 
          (c) a director who is a member of the immediate family of an
     individual who is, or as been in any of the past three years, employed by
     the corporation or any of its affiliates as an executive officer. Immediate
     family includes a person's spouse, parents, children, siblings,
     mother-in-law, father-in-law, brother-in-law, sister-in-law, son-in-law,
     daughter-in-law, and anyone who resides in such person's home;
 
          (d) a director who is a partner in, or a controlling shareholder or an
     executive officer of, any for-profit business organization to which the
     corporation made, or from which the corporation received, payments (other
     than those arising solely from investments in the corporation's securities)
     that exceed 5% of the corporation's or business organization's consolidated
     gross revenues for that year, or $200,000, whichever is more, in any of the
     past three years;
 
          (e) a director who is employed as an executive of another entity where
     any of the company's executives serve on that entity's compensation
     committee.
 
Each issuer shall maintain a sufficient number of independent directors on its
board of directors to satisfy the audit committee requirement set forth in Rule
4310(c)(26)(B).
 
RULE 4310(c)(26)
 
     (B) Audit Committee Composition
 
          (i) Each issuer must have, and certify that it has and will continue
     to have, an audit committee of at least three members, comprised solely of
     independent directors, each of whom is able to read and understand
     fundamental financial statements, including a company's balance sheet,
     income statement, and cash flow statement or will become able to do so
     within a reasonable period of time after his or her appointment to the
     audit committee. Additionally, each issuer must certify that it has, and
     will continue to have, at least one member of the audit committee that has
     past employment experience in finance or accounting, requisite professional
     certification in accounting, or any other comparable experience or
     background which results in the individual's financial sophistication,
     including being or having been a chief executive officer, chief financial
     officer or other senior officer with financial oversight responsibilities.
 
          (ii) Notwithstanding paragraph (i), one director who is not
     independent as defined in Rule 4200, and is not a current employee or an
     immediate family member of such employee, may be appointed to the audit
     committee, if the board, under exceptional and limited circumstances,
     determines that membership on the committee by the individual is required
     by the best interests of the corporation and its shareholders, and the
     board discloses, in the next annual proxy statement subsequent to such
     determination, the nature of the relationship and the reasons for that
     determination.
