     The Board of Directors of the Company is soliciting the enclosed proxy for
use at the Annual Meeting of Stockholders to be held on August 13, 1997, at 8:30
a.m., at the Del Mar Hilton, 15575 Jimmy Durante Boulevard, Del Mar, California.

return the proxy in the enclosed envelope.
 
     A proxy may be revoked by written notice to the Secretary of the Company at
any time prior to the voting of the proxy, or by executing a later proxy or by
attending the meeting and voting in person. Unrevoked proxies will be voted in
accordance with the instructions indicated in the proxies, or if there are no
such instructions, such proxies will be voted for the election of the Board's
nominee for director. 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 or "broker
non-votes" do not constitute a vote "for" or "against" any matter and thus will
be disregarded in the calculation of "votes cast."

entitled to vote at the meeting. As of that date, 7,745,041 shares of common
stock, par value $.0001 per share ("Common Stock"), of the Company were

the outstanding shares of the Company, represented in person or by proxy at the
meeting, constitutes a quorum. A plurality of the votes cast at the meeting is
required to elect directors.
 
     The cost of preparing, assembling and mailing the Notice of Annual Meeting,
Proxy Statement and proxy will be borne by the Company.

COMPENSATION PLANS
 
     401(k) Plan. The Company has established a tax-qualified employee savings
and retirement plan (the "401(k) Plan") effective January 1990 covering all
employees who have been employed by the Company for at least 90 days and who are
at least 21 years of age. Pursuant to the 401(k) Plan, 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 such 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 the Company. 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 (the "Code") so that contributions to the 401(k) Plan, and
 
                                        7

<PAGE>   10
 
income earned on plan contributions, are not taxable to employees until
withdrawn from the 401(k) Plan, and so that contributions by the Company are
deductible by the Company when made for income tax purposes.
 
     Employee Stock Purchase Plan. The Company has established the ViaSat, Inc.
Employee Stock Purchase Plan (the "Employee Stock Purchase Plan") to assist
employees of the Company in acquiring a stock ownership interest in the Company
and to encourage them to remain in the employment of the Company. The Employee
Stock Purchase Plan is intended to qualify under Section 423 of the Code. A
maximum of 250,000 shares of Common Stock are reserved for issuance under the
Employee Stock Purchase Plan. The Employee Stock Purchase Plan permits eligible
employees to purchase Common Stock at a discount through payroll deductions
during specified six-month offering periods. No employee may purchase more than
$25,000 worth of stock in any calendar year. The price of shares purchased under
the Employee Stock Purchase Plan will be equal to 85% of the fair market value
of the Common Stock on the first or last day of the offering period, whichever
is lower. The Employee Stock Purchase Plan is administered by the Compensation
Committee. As of March 31, 1997, there were no shares purchased under the
Employee Stock Purchase Plan.
 
     1993 Stock Option Plan. In 1993, the Company adopted the ViaSat, Inc. 1993
Stock Option Plan (the "1993 Stock Option Plan") to enable key employees,
consultants and non-employee directors of the Company to acquire a proprietary
interest in the Company, and thus to create in such persons an increased
interest in and a greater concern for the welfare of the Company. The 1993 Stock
Option Plan provided for aggregate option grants of up to 733,500 shares. As of
March 31, 1997, options to purchase an aggregate of 351,652 shares of Common
Stock at prices ranging from $0.34 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. The Company has adopted the ViaSat, Inc.
1996 Equity Participation Plan (the "1996 Equity Participation Plan") designed
to update and replace the 1993 Stock Option Plan. The 1996 Equity Participation
Plan provides for the grant to executive officers, other key employees,
consultants and non-employee directors of the Company of a broad variety of
stock-based compensation alternatives such as nonqualified stock options,
incentive stock options, restricted stock and performance awards. The 1996
Equity Participation Plan is administered by the Compensation Committee, which
is authorized to select from among the eligible participants the individuals to
whom options, restricted stock purchase rights and performance awards are to be
granted and to determine the number of shares to be subject thereto and the
terms and conditions thereof. The Compensation Committee is also authorized to
adopt, amend and rescind rules relating to the administration of the 1996 Equity
Participation Plan. A maximum of 750,000 shares of Common Stock are reserved for
issuance under the 1996 Equity Participation Plan. As of March 31, 1997, options
to purchase an aggregate of 175,000 shares of Common Stock at prices ranging
from $9.00 to $10.75 were outstanding under the 1996 Equity Participation Plan.
 
     For fiscal 1997, 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 1997.
 
     Compensation Committee Interlocks and Insider Participation. Prior to the
Company's initial public offering in December 1996, each director of the
Company, including Mark D. Dankberg, Chairman, President and Chief Executive
Officer of the Company, participated in all discussions and decisions regarding
salaries and incentive compensation for all employees and consultants of the
Company, except that Mr. Dankberg was excluded from discussions regarding his
own salary and incentive compensation. Following the Company's initial public
offering, the Company established a Compensation Committee to handle all such
compensation matters, which was comprised during the remainder of fiscal 1997 of
Dr. Jeffery M. Nash and James W. Bunker.
 
     Dr. Robert W. Johnson, individually, and B. Allen Lay, through his position
as a General Partner of SCV, had an interest in the Company's sale of Series A
Convertible Preferred Stock and the related transactions described under
"Certain Transactions."

R
EPORT ON EXECUTIVE COMPENSATION
 
     The Compensation Committee (the "Committee") is responsible for
administering the Company's compensation policies and practices and approves all
elements of compensation for executive officers. The Committee reports regularly
to the Board of Directors on its activities. In general, the compensation
policies adopted by the Committee were designed to: (i) attract and retain
executives capable of leading the Company to meet its business objectives and
(ii) motivate the Company's executives to enhance long-term stockholder value.
 
  Executive Officer Compensation
 
     The Company's 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.
 
     The Company's compensation program for executive officers is designed to
provide a total compensation level (including both annual and long-term
incentives) that is competitive with survey companies. For executive officers
recently recruited by the Company, annual compensation rates and long-term
incentive awards reflect amounts necessary to attract them to the 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 are representative of the firms the Company competes with for executive
talent and have jobs similar to those at the Company in magnitude, complexity
and scope of responsibility, form the basis for the survey group used by the
Committee.
 
  Components of Executive Compensation
 
     BASE SALARY is established by the Committee based on an executive's job
responsibilities, level of experience, individual performance and contribution
to the business, and information obtained from surveys. The Committee believes
that the executives' base salaries are at competitive levels relative to the
various markets from which the Company attracts its executive talent.
 
     ANNUAL CASH INCENTIVE BONUS is established by the Committee at the end of
the fiscal year and is based on the 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
the Company, and award levels at companies in the survey group. Long-term
incentives granted in prior years are also taken into consideration. For fiscal
1997, the 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 1997.
 
  Compensation for the Chairman and Chief Executive Officer
 
     Mr. Dankberg continues to provide outstanding personal leadership as the
Chief Executive Officer of the Company. Under Mr. Dankberg's direction, the
Company has achieved eleven consecutive years of internally generated revenue
growth and ten consecutive years of profitability, and is well positioned to
benefit from its successes in developing and deploying products which utilize
Demand Assigned Multiple Access satellite networking technology. The Company's
fiscal 1997 achievements in revenue growth, order backlog, product development
and shipments were consistent with the Company's objectives. During fiscal 1997,
Mr. Dankberg earned a base salary of $190,865, a 16% increase over the prior
year. In light of the leadership he demonstrated during the year, in July 1996,
the Committee granted Mr. Dankberg a stock option to purchase 14,670 shares
 
                                        9

<PAGE>   12
 
of Common Stock at $4.50 per share (110% of the fair market value at the time of
grant), and the Committee determined that Mr. Dankberg should receive a $35,000
bonus.
 
  Deductibility of Compensation in Excess of $1 Million Per Year
 
     Section 162(m) of the 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 certain requirements are met. For 1997 and
1998, the Company does not anticipate that there will be nondeductible
compensation for the Company positions in question. The Committee plans to
continue to review the matter for 1998 and future years in order to determine

                              CERTAIN TRANSACTIONS
 
     In June 1986, the Company sold 3,000,000 shares of Series A Convertible
Preferred Stock to SCV and certain of its affiliates, including Robert W.
Johnson, a director of the Company, at a price of $0.10 per share in a private
placement transaction. Each outstanding share of Series A Convertible Preferred
Stock was automatically converted into one share of Common Stock upon the
closing of the Company's initial public offering in December 1996.
 
     In connection with the sale of the Series A Convertible Preferred Stock in
June 1986, the Company entered into a Shareholders Agreement with SCV and
certain of its affiliates, including Robert W. Johnson, a director of the
Company, providing for the corporate governance of the Company. The Shareholders
Agreement was terminated upon the closing of the Company's initial public
offering.
 
 
                  RELATIONSHIP WITH INDEPENDENT ACCOUNTANTS

been examined by Price Waterhouse LLP. Representatives of Price Waterhouse LLP
are expected to be available at the meeting to respond to appropriate questions
and to make a statement if they desire to do so. The Company will select
independent accountants for the current year sometime after the meeting.

                            SECTION 16(a) REPORTING
 
     Under Section 16(a) of the Exchange Act, 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 its
review of such forms received by it, or written representations from certain
Reporting Persons that no such forms were required, the Company is aware of the
following instances of noncompliance, or late compliance, with such filing
requirements during fiscal 1997 by its directors, executive officers and
beneficial owners of 10% or more of the Common Stock: In January 1997, each of
the Company's executive officers and directors filed a late Form 3 to report the
initiation of such person's status as a Reporting Person following the Company's
initial public offering in December 1996.
