                                PROXY STATEMENT
 
         FOR THE ANNUAL MEETING OF STOCKHOLDERS TO BE HELD MAY 6, 1997
 
     This proxy statement is furnished in connection with the solicitation of
proxies to be voted at the Annual Meeting of Stockholders of APACHE Medical
Systems, Inc. (the "Company" or "APACHE"), to be held on Tuesday, May 6, 1997.
This proxy statement and the proxy are being mailed to stockholders on or about
March 26, 1997.
 
     The enclosed proxy is solicited by the Board of Directors of the Company
and will be voted at the Annual Meeting and any adjournments thereof. Shares
represented by a properly executed proxy in the accompanying form will be voted
at the Annual Meeting in accordance with any instructions specified by the
stockholder. If no instructions are given, the stockholder's shares will be
voted in accordance with the recommendations of the Board of Directors FOR each
of the proposals presented in this proxy statement. Those recommendations are
described later in this proxy statement.
 
     The proxy may be revoked at any time before it is exercised by delivering a
written notice of revocation to the Secretary of the Company. If you attend the
Annual Meeting in person, you may revoke your proxy by either giving notice of
revocation to the inspectors of election at the Annual Meeting or by voting at
the Annual Meeting in person.
 
     The only items of business that the Board of Directors intends to present
or knows will be presented at the Annual Meeting are the items discussed in this
proxy statement. The proxy confers discretionary authority upon the persons
named therein, or their substitutes, to vote on any other items of business that
may properly come before the meeting.
 
     As of March 10, 1997, the record date for the Annual Meeting, the Company
had 6,871,353 shares of Common Stock, par value $.01 per share ("Common Stock"),
issued and outstanding. Each share is entitled to one vote. A majority of the
issued and outstanding shares constitutes a quorum at the meeting.
 
                             ELECTION OF DIRECTORS
 
     Six directors are to be elected to serve for a term of one year or until
their respective successors are duly elected and qualified. Directors are
elected by a plurality of the votes of the shares of Common Stock present in
person or represented by proxy and entitled to vote at the Annual Meeting.
Consequently, any shares not voted (whether by abstention, broker non-vote or
votes withheld) will have no effect on the election of directors. Unless
otherwise directed, proxies will be voted at the Annual Meeting for the election
of the six nominees listed below, or in the event of a contingency not presently
foreseen, for different persons as substitutes. The Board of Directors is
recommending this slate.

                 INFORMATION CONCERNING THE BOARD OF DIRECTORS
                               AND ITS COMMITTEES
 
     During the 1996 fiscal year, there were five meetings of the Board of
Directors and six telephonic meetings. Each Director attended at least 75% of
the aggregate total number of the meetings of the Board of Directors and the
meetings of the Board Committees on which he served, except for Mr. Lewin who
attended seven of the 11 Board meetings and one of the two Audit Committee
meetings.
 
COMMITTEES OF THE BOARD OF DIRECTORS
 
     The Board of Directors has standing Audit and Compensation Committees,
which deal with certain specific areas of the Board's responsibility.
 
     The Audit Committee, which met two times in conjunction with meetings of
the Board of Directors during the 1996 fiscal year, recommends the firm to be
appointed as independent public accountants to audit the Company's financial
statements and reviews the scope and results of the audit and other services
provided by the Company's independent public accountants. The members of the
Audit Committee are Edward J. Connors, Thomas W. Hodson, Lawrence S. Lewin and
Francis G. Ziegler.
 
     The Compensation Committee, which met four times during the 1996 fiscal
year, develops the Company's executive compensation philosophy and reviews and
recommends the compensation programs for officers of the Company, including
salaries and incentive compensation. The Compensation Committee also administers
the Employee Stock Option Plan and the Employee Stock Purchase Plan. The members
of the Compensation Committee are Thomas W. Hodson, William A. Knaus, M.D. and
Francis G. Ziegler.
 
DIRECTOR COMPENSATION
 
     Directors who are not currently receiving compensation as officers or
employees of the Company are entitled to reimbursement of expenses for attending
each meeting of the Board of Directors and each meeting of any committee.
 
     The Company's directors who are not employees of the Company are eligible
to participate in the Company's Non-Employee Director Stock Option Plan (the
"Director Option Plan"). The Director Option Plan is administered by the
Chairman of the Board of Directors along with other employee directors, if any,
selected by the Chairman. Pursuant to the Director Option Plan, non-employee
directors of the Company will receive options to purchase 2,500 shares of Common
Stock for each year of service. The exercise price of the options is the fair
market value of the Company's Common Stock on the date of grant. Stock options
granted under the Director Option Plan have a term of 10 years and are not
exercisable during the first 12 months following grant. The Company has reserved
70,000 shares of Common Stock for issuance under the Director Option Plan. The
Director Option Plan may be terminated by the Board of Directors at any time.
Upon the occurrence of a Change of Control, as defined in the Director Option
Plan, all outstanding unvested options under the Director Option Plan
immediately vest.
 
     William A. Knaus, M.D. is the Chief Scientific Advisor of the Company.
While Dr. Knaus is not directly compensated for his services in that capacity,
the Company does pay the University of Virginia, his current employer, for
services rendered to the Company by Dr. Knaus.
 
                    AMENDMENT AND RESTATEMENT OF CERTIFICATE
                 OF INCORPORATION TO AUTHORIZE PREFERRED STOCK
                AND TO ELIMINATE CERTAIN INAPPLICABLE PROVISIONS
 
     The Board of Directors of the Company has adopted a resolution approving
and recommending to the Company's stockholders for their approval a proposal to
further amend and restate the Company's Amended
 
                                        3
<PAGE>   7
 
and Restated Certificate of Incorporation to (i) create 10,000,000 shares of
"Blank Check" Preferred Stock, par value $.01 per share (the "Preferred Stock"),
and (ii) eliminate certain provisions of the Amended and Restated Certificate of
Incorporation that are no longer applicable (the "Proposed Amendment and
Restatement").
 
AUTHORIZATION OF PREFERRED STOCK
 
     The term "Blank Check" Preferred Stock refers to stock for which the
designations, preferences, conversion rights, cumulative, relative
participating, optional or other rights, including voting rights,
qualifications, limitations or restrictions thereof (collectively, the
"Limitations and Restrictions") are determined by the board of directors of a
company. Upon approval of the Proposed Amendment and Restatement, the Board of
Directors of the Company will be entitled to authorize the creation and issuance
of 10,000,000 shares of Preferred Stock in one or more series with such
Limitations and Restrictions as may be determined by the Board of Directors with
no further authorization by stockholders.
 
     The Board of Directors is required to make any determination to issue
shares of Preferred Stock based on its judgment as to the best interests of the
Company's stockholders. Presently, the Board of Directors intends to create a
series of Preferred Stock comprised of 30,000 shares of Series A Junior
Participating Preferred Stock, par value $.01 per share (the "Junior Preferred
Stock"), to be reserved for issuance upon the exercise of Preferred Stock
Purchase Rights created pursuant to the terms of the Stockholder Rights Plan
described below. The terms of the Junior Preferred Stock are described below
under the caption "Stockholder Rights Plan -- Description of Junior Preferred
Stock."
 
     While the Board of Directors has no present intention to do so, it could
issue up to an additional 9,970,000 shares of Preferred Stock that could,
depending on the terms of a series, make more difficult or discourage an attempt
to obtain control of the Company by merger, tender offer, proxy contest or other
means. When in the judgment of the Board of Directors this action will be in the
best interest of the stockholders and the Company, Preferred Stock could be used
to create voting or other impediments or to discourage persons seeking to gain
control of the Company. The Company is not aware of any current efforts to
acquire control of the Company.
 
     The issuance of additional shares of Preferred Stock could be used to
dilute the stock ownership of a person or entity seeking to obtain control of
the Company, or could result in a private placement with purchasers who might
side with the Board of Directors if they choose to oppose a specific change of
control. Moreover, the Board of Directors could authorize holders of a series of
Preferred Stock to vote either separately as a class or with the holders of the
Company's Common Stock on any merger, sale or exchange of assets by the Company
or any other extraordinary corporate transaction.
 
     Securities laws require the disclosure of any provisions contained in the
Company's charter or by-laws that arguably could have an anti-takeover effect.
Like many publicly-held companies, the by-laws of the Company restrict the
ability of its stockholders to call a special meeting. The Company's by-laws
provide that special meetings may be called only by the President or Chairman of
the Board and that a special meeting must be called by the President, Chairman
of the Board or Secretary only upon the written request of a majority of the
holders of Common Stock of the Company. Such a provision could delay, deter or
otherwise make more difficult a takeover of the Company. While permitted under
Delaware law, the Company's charter and by-laws do not provide stockholders with
cumulative voting.
 
     Although the Company may consider effecting an equity offering of Preferred
Stock in the future for the purpose of raising additional working capital or
otherwise, the Company currently has no agreements or understandings with any
third party to effect such an offering or to purchase any shares offered in
connection with such an offering, and no assurances are given that any offering
will in fact be effected. Furthermore, the Board of Directors has no present
intention to create any series of Preferred Stock other than the Junior
Preferred Stock. Consequently, the terms of any Preferred Stock subject to this
proposal cannot be stated or estimated with respect to any of the securities
authorized other than with respect to the Junior Preferred Stock.

STOCKHOLDER RIGHTS PLAN
 
     PLAN OVERVIEW.  The Board of Directors adopted a Stockholder Rights Plan
(the "Rights Plan") at a meeting held on January 28, 1997. The Rights Plan will
be implemented upon stockholder approval of the Proposed Amendment and
Restatement. In connection with the adoption of the Rights Plan, and subject to
stockholder approval of the Proposed Amendment and Restatement, the Board has
declared a dividend distribution of one Preferred Stock Purchase Right (a
"Right") for each outstanding share of Common Stock that will be outstanding on
June 2, 1997 (the "Rights Record Date").
 
     In the event that the Proposed Amendment and Restatement is not approved by
the stockholders, the Rights Plan as adopted by the Board on January 28, 1997
will not be implemented. The Board has indicated, however, that, in such an
event, it will consider the adoption of an alternative form of stockholder
rights plan that would not require the approval of stockholders or the creation
of a new class of stock.
 
     The Rights Plan contains provisions that are designed to protect the
Company's stockholders in the event of an unsolicited attempt to acquire the
Company, including a gradual accumulation of shares in the open market, a
partial or two-tiered tender offer that does not treat all stockholders equally
and other takeover tactics that the Board of Directors believes may be abusive
and not in the best interests of the Company's stockholders. The Board believes
that these tactics tend to unfairly pressure stockholders, coerce them to
relinquish their investment without giving them any meaningful choice and
deprive them of the full value of their shares.
 
     The implementation of the Rights Plan increases the ability of the Board to
effectively represent the interests of the Company's stockholders in the event
of an unsolicited proposal. The Rights Plan will give the Board of Directors an
opportunity to evaluate an offer and exercise good faith business judgment and,
if necessary, to take appropriate steps to protect and advance stockholder
interests by negotiating with the bidder, auctioning the Company, implementing a
recapitalization or restructuring designed as an alternative to the offer, or
taking other action.
 
     Although the Rights Plan is intended to benefit the Company's stockholders,
it also could have the effect of discouraging tender offers or other attempts to
obtain control of the Company and thereby make more difficult the removal of
incumbent management. The Rights Plan, however, does not inhibit stockholders
from utilizing the proxy mechanism to promote a change in the management or
direction of the Company.
 
     CONSIDERATION OF THE BOARD OF DIRECTORS.  In adopting the Rights Plan, the
Board of Directors considered numerous factors. The Company has traditionally
emphasized management policies designed to take into account the interests of
its stockholders. Similarly, the Board has indicated that it believes its
adherence to these policies has been a key factor in the Company's growth and
that maintaining the Company as an independent entity best ensures the
continuation of these management policies. The Board has reviewed various forms
of defensive measures designed to enable the Company to maintain its
independence and has determined that the implementation of the Rights Plan is
desirable.
 
     DESCRIPTION OF JUNIOR PREFERRED STOCK.  Junior Preferred Stock purchasable
upon exercise of the Rights will not be redeemable. Each share of Junior
Preferred Stock will be entitled to a minimum preferential quarterly dividend
payment of $1 per share, but will be entitled to an aggregate dividend of 1,000
times the dividend declared per share of the Company's Common Stock. In the
event of liquidation, the holders of the Junior Preferred Stock will be entitled
to a minimum preferential liquidation payment of $1,000 per share, but will be
entitled to an aggregate payment of 1,000 times the payment made per share of
Common Stock. Each share of Junior Preferred Stock will have 1,000 votes, voting
together with the Common Stock. In the event of any merger, consolidation or
other transaction in which Common Stock is exchanged, each share of Junior
Preferred Stock will be entitled to receive 1,000 times the amount received per
share of Common Stock. The rights of the Junior Preferred Stock will be
protected by customary antidilution provisions.
 
     DESCRIPTION OF RIGHTS.  Initially the Rights will trade with, and cannot be
separated from, the outstanding shares of the Company's Common Stock. With
respect to any shares of Common Stock outstanding as of the Rights Record Date,
the Rights will be evidenced by the Common Stock certificates and the Summary of
Rights to Purchase Preferred Shares, which will be distributed to all holders of
record as of
 
                                        5
<PAGE>   9
 
the Rights Record Date. Ten days after a person or group of affiliated or
associated persons (excluding certain entities related to the Company) either
acquires 15% or more of the Common Stock or announces or commences a tender or
exchange offer that would result in such person or group acquiring beneficial
ownership of 30% or more of the Common Stock, the Rights will become exercisable
and separate certificates representing the Rights will be distributed. The Board
of Directors expects that the Rights will be traded independently from the
Common Stock at that time. At no time will the Rights have any voting power.
 
     When the Rights become exercisable, a Right holder will be entitled to
purchase from the Company one one-thousandth of a share of Junior Preferred
Stock for $60. If the Company is involved in a merger or other business
combination at any time after the Rights become exercisable, each Right will
entitle a holder to buy a number of shares of common stock of the acquiring
company having a market value equal to twice the exercise price of each Right.
Alternatively, if any person or group acquires 15% or more of the Company's
Common Stock, the Rights will entitle the holder other than such person or any
member of such group, to buy a number of shares of Common Stock of the Company
having a market value equal to twice the exercise price of each Right.
 
     The Rights may be redeemed by the Company at a price of $.01 per Right at
any time before any person acquires beneficial ownership of 15% or more of the
Common Stock. In addition, at any time after any person acquires beneficial
ownership of 15% or more of the Common Stock and prior to such person's
acquisition of 50% or more of the Common Stock, the Board of Directors may elect
to exchange all or part of the Rights for Common Stock at an exchange ratio of
one share of Common Stock (or of a share of a class or series of the Company's
Preferred Stock having equivalent rights, preferences and privileges) per Right
(subject to adjustment for stock splits, stock dividends and other similar
actions).
 
     REASON FOR ADOPTION.  The Board of Directors has adopted the Rights Plan
with a view toward ensuring the Company's continued independence and ability to
focus on long-term goals. The Rights are not intended to prevent a takeover of
the Company and will not preclude a successful cash tender offer for all of the
outstanding shares of the Common Stock coupled with a requirement for the tender
of Rights formerly attached to such shares. The Board of Directors believes,
however, that the Rights should discourage most efforts to acquire the Company
(short of an all inclusive tender offer) in a manner or on terms not approved by
the Board. The Rights are designed to deal with an acquiror's potential use of
coercive tactics to deprive the Company's Board and stockholders of a reasonable
opportunity to determine the future of the Company.
 
     EFFECTS OF THE RIGHTS PLAN.  The Rights Plan will not result in any change
in the corporate structure of the Company. The issuance of the Rights has no
dilutive effect, will not affect reported earnings per share, and will not
change the way in which stockholders can trade the Common Stock. The Rights
should not interfere with any merger or other business combination approved by
the Board of Directors prior to the time a person or group has acquired
beneficial ownership of 15% or more of the Common Stock, since until such time
the Rights may be redeemed by the Company at $.01 per Right.
 
     It is the intention of the Board of Directors that the Rights Plan will
encourage potential acquirors of the Company to negotiate at arms-length with
the Company's management and Board. The Rights Plan could, however, have the
effect of discouraging tender offers or other attempts to obtain control of the
Company, some of which might be beneficial to the Company and it stockholders,
since acquirors may be deterred by the substantial economic and voting power
dilution to their holdings of the Company's Common Stock that would result
should the Board determine not to redeem the Rights.
 
     Moreover, since the Rights Plan is designed to discourage accumulations of
large blocks of Common Stock by purchasers whose objective is to receive a
substantial profit by having the Common Stock repurchased by the Company or a
third party at a premium, the Rights Plan could tend to reduce temporary
fluctuations in the market price of the Company's Common Stock that are due to
the accumulation of such blocks. The Company's stockholders could therefore be
deprived of opportunities to sell their stock at a temporarily higher market
price.
 
     The Board of Directors of the Company will consider the fairness of the
financial and other terms of an offer to its stockholders. The Rights Plan does
not relieve the Board of Directors of its fiduciary obligation to
 
                                        6
<PAGE>   10
 
consider in good faith any proposal to acquire the Company and does not permit
the Board to act to the detriment of the Company's stockholders for the purpose
of entrenching management.
 
ELIMINATION OF CERTAIN INAPPLICABLE PROVISIONS
 
     Upon the consummation of the Company's initial public offering in July
1996, all of the shares of the Company's issued and outstanding Series A
Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, Series D
Preferred Stock, Series E Preferred Stock and Series F Preferred Stock were
converted into shares of Common Stock. Consequently, the Proposed Amendment and
Restatement eliminates provisions of the Company's Amended and Restated
Certificate of Incorporation that relate to these series of Preferred Stock,
which are no longer outstanding. In addition, the Proposed Amendment and
Restatement eliminates language that provided for a stock split upon the
effectiveness of the Company's initial public offering.
 
REQUIRED VOTE
 
     The Proposed Amendment and Restatement to authorize Preferred Stock and to
eliminate certain inapplicable provisions requires the affirmative vote of a
majority of the outstanding shares. Consequently, abstentions from voting and
broker non-votes will be counted as votes against the Proposed Amendment and
Restatement since they are less votes for approval.
 
     If the Board's proposal is approved by stockholders, the Proposed Amendment
and Restatement will become effective upon the filing of a Certificate of
Amendment and Restatement in accordance with the General Corporation Law of
Delaware.
 
     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE
FOR THIS PROPOSAL TO FURTHER AMEND AND RESTATE THE COMPANY'S AMENDED AND
RESTATED CERTIFICATE OF INCORPORATION.
 
                          AMENDMENT AND RESTATEMENT OF
                           EMPLOYEE STOCK OPTION PLAN
 
     The Board of Directors of the Company has adopted, and recommends to
stockholders for approval, the further amendment and restatement of the Employee
Stock Option Plan of APACHE Medical Systems, Inc. (the "Employee Option Plan")
to (i) increase the number of shares reserved for issuance under the Employee
Option Plan from 1,700,000 to 2,200,000, (ii) allow the Board maximum
flexibility in amending the Employee Option Plan as permitted by the recently
revised securities regulations relating to employee benefit plans, (iii) conform
certain technical aspects of the Employee Option Plan to these securities
regulations and (iv) eliminate qualifications in the Employee Option Plan that
relate to the Company's then anticipated initial public offering of Common
Stock, which has since been effected. The description of the Employee Option
Plan set forth below is qualified in its entirety by reference to the full text
of the Amended and Restated Employee Stock Option Plan, which is attached as
Appendix A to this proxy statement.
 
THE EMPLOYEE OPTION PLAN
 
     GENERALLY.  The Employee Option Plan as adopted by the Board of Directors
of the Company and approved by the Company's stockholders was originally
effective as of November 8, 1990 and was amended and restated effective April 1,
1996. The Employee Option Plan provides for the grant of stock options to
employees of the Company or its subsidiaries, including employees who are
officers and/or members of the Board, and to any non-employee (with the
exception of non-employee directors) who is a consultant or advisor to the
Company. Unless terminated sooner by the Board, the Employee Option Plan will
terminate on April 1, 2006.
 
     SHARES SUBJECT TO THE PLAN.  The Company has reserved 1,700,000 shares of
Common Stock for issuance under the Employee Option Plan. A description of the
Board's proposal to increase the number of reserved shares to 2,200,000 shares
is included below under the caption "Proposed Amendment and Restatement of the
Employee Option Plan -- Increase Number of Shares Reserved for Issuance." As of
March 10, 1997, options on 1,273,020 shares of Common Stock were outstanding
under the Employee Option Plan.
 
                                        7
<PAGE>   11
 
     PLAN ADMINISTRATION.  The Employee Option Plan is administered by the
Compensation Committee of the Board. The Committee has the authority and
discretion, subject to the provisions of the Employee Option Plan, to select
persons to whom options will be granted, to designate the number of shares to be
covered by options, to specify the type of consideration to be paid to the
Company, and to establish all other terms and conditions of each stock option.
 
     TERMS AND CONDITIONS OF OPTIONS.  The exercise price for a stock option may
not be less than the fair market value of the Company's Common Stock on the date
the stock option is granted. Stock options granted under the Employee Option
Plan may not be transferred other than by will or by the laws of descent and
distribution. Upon the occurrence of a Change of Control, as defined in the
Employee Option Plan, all outstanding unvested options under the Employee Option
Plan immediately vest.
 
     NATURE OF OPTIONS.  Options granted under the Employee Option Plan may be
either "incentive stock options" ("ISOs"), as defined under the tax laws, or
non-qualified stock options. ISOs may be granted only to employees of the
Company and are subject to certain additional limitations relating to such
things as employment status, minimum exercise price, length of the exercise
period, maximum value of the stock underlying the options and a required holding
period for stock received upon exercise of an ISO.
 
     PLAN AMENDMENT.  The Employee Option Plan currently provides that a
majority of the Board of Directors of the Company may, without further action of
the stockholders, terminate, alter, amend or suspend the Employee Option Plan,
provided that the Board may not materially increase participants' benefits or
the number of shares issuable under the Employee Option Plan, materially modify
the eligibility requirements for participation in the Employee Option Plan, or
take any action that would cause the Employee Option Plan to fail to comply with
certain applicable federal tax or securities laws. In addition, any action taken
by the Board may not materially and adversely affect any options outstanding
under the Employee Option Plan without the consent of the participants. A
discussion of the Board's proposal to increase its flexibility in amending the
Employee Option Plan as permitted by the recently revised securities regulations
is included below under the caption "Proposed Amendment and Restatement of the
Employee Option Plan -- Board of Directors' Ability to Amend."
 
     TAX CONSEQUENCES.  Certain federal income tax consequences are associated
with (i) the grant of a stock option under the Employee Option Plan, (ii) the
exercise of such option and (iii) the disposition of shares received upon the
exercise of an option. The following description of tax consequences is based
upon present federal tax laws and regulations, but does not purport to be a
complete description of the federal income tax consequences applicable to a
participant under the Employee Option Plan. Accordingly, information relating to
tax consequences is qualified in its entirety by reference to current tax laws.
 
     NON-QUALIFIED STOCK OPTIONS.  The grant of a non-qualified option
(including any option exceeding any additional limitations on ISOs) to a
participant will not be a taxable event so long as the option does not have a
readily ascertainable fair market value. Options granted pursuant to the
Employee Option Plan should not have a readily ascertainable fair market value
because they are not actively traded on an established securities market, are
not transferable, are not immediately exercisable in full upon grant and have
more than a nominal exercise price. Accordingly, the participant will not be
subject to any income tax consequences with respect to such option unless and
until the option is exercised.
 
     Upon the exercise of a non-qualified stock option, the participant
generally must recognize ordinary compensation income equal to the "spread"
between the exercise price and the fair market value of the Common Stock on the
date of exercise. The amount and character of any gain or loss realized on a
subsequent disposition of Common Stock by the participant generally would depend
on, among other things, whether an election under the Internal Revenue Code of
1986, as amended (the "Code") Section 83(b) with respect to such shares had been
made and the length of time such shares had been held.
 
     INCENTIVE STOCK OPTIONS.  There are no federal income tax consequences
associated with the grant of an ISO to an employee. In contrast to the exercise
of a non-qualified stock option, the exercise of an ISO will not cause an
employee to recognize taxable income for regular income tax purposes (although
the employee could be subject to an alternative minimum tax liability as
described below). If the employee holds the shares
 
                                        8
<PAGE>   12
 
acquired upon exercise of the ISO for a minimum of two years from the date of
the grant of the ISO, and for at least one year after exercise, any gain
realized by the participant on the subsequent sale or exchange of such shares
generally would be treated as long-term capital gain. The amount of this gain
generally will equal the "spread" between the sales price and the exercise price
of the Common Stock. If the shares are sold or otherwise disposed of prior to
the expiration of such periods (a "disqualifying disposition"), then a portion
of any gain recognized by the employee that would otherwise be characterized as
capital gain would instead be taxable as ordinary compensation income. The
amount of such gain that would be characterized as ordinary income would not
exceed an amount equal to the excess of (i) the fair market value of such shares
as of the date the option was exercised over (ii) the amount paid for such
shares. Any loss recognized upon a taxable disposition of the shares generally
would be characterized as a capital loss.
 
     Upon exercise of an ISO by an employee, the alternative minimum taxable
income of such employee must be determined as if such ISO were a non-qualified
stock option. Accordingly, he or she will be required to include as alternative
minimum taxable income the excess (if any) of the value of the shares received
upon exercise as of the date such shares are vested over the amount paid for
such shares. He or she would then be required to pay the greater of his or her
regular or alternative minimum tax liability computed with respect to such year.
 
     WITHHOLDING TAXES.  The Company may condition the exercise of any option
under the Employee Option Plan on the receipt of an amount sufficient to pay,
and will deduct from the compensation of a holder of an option under the
Employee Option Plan, the amount of any tax required by any governmental
authority to be withheld and paid over by the Company to such governmental
authority for the account of the participant with respect to such options and
the exercise thereof.
 
     COMPENSATION DEDUCTION.  To the extent compensation income is recognized by
a participant in connection with the exercise of a non-qualified stock option or
a "disqualifying disposition" of stock obtained upon exercise of an ISO, the
Company generally will be entitled to a corresponding compensation deduction
(assuming the withholding requirements are satisfied).
 
     OUTSTANDING OPTIONS.  The number of shares acquirable pursuant to stock
options that will be awarded to the Company's Chief Executive Officer and the
other four most highly compensated executive officers of the Company under the
Employee Option Plan is not currently determinable. As of February 28, 1997,
options to purchase an aggregate of 849,446 shares had been granted under the
Employee Option Plan to the Company's Chief Executive Officer and the other four
most highly compensated executive officers as follows: 550,177 to Dr. Bisbee
(Chairman and Chief Executive Officer); 187,413 to Mr. Ciri (President and Chief
Operating Officer); 40,212 to Ms. Jones (Vice President, New Business
Development); 71,644 to Mr. Umidi (Vice President, Finance and Administration,
Treasurer and Chief Financial Officer) and none to Ms. Draper (Executive Vice
President and Secretary). As of the same date, options to purchase 929,657
shares had been granted to all current executive officers as a group. In
addition, options to purchase 41,960 shares had been awarded pursuant to the
Employee Option Plan to all current directors who are not executive officers as
a group and the nominees for election as a director, in addition to Dr. Bisbee,
had been granted options to purchase the following number of shares: 10,490 to
Mr. Connors, 10,490 to Mr. Hodson, none to Dr. Knaus, 10,490 to Mr. Lewin, and
10,490 to Mr. Ziegler. Also as of February 28, 1997, options to purchase 343,363
shares had been granted to plan participants, including all current officers who
are not executive officers, as a group. On March 19, 1997, the last reported
sale price of the Common Stock on the Nasdaq National Market was $6.125 per
share.
 
PROPOSED AMENDMENT AND RESTATEMENT OF THE EMPLOYEE OPTION PLAN
 
     INCREASE NUMBER OF SHARES RESERVED FOR ISSUANCE.  As of March 10, 1997,
stock options covering 1,273,020 shares of Common Stock were outstanding under
the Employee Option Plan and 423,569 shares were available for future awards.
The Board of Directors proposes that the Employee Option Plan be amended and
restated to increase the aggregate number of shares of Common Stock that may be
issued under the Employee Option Plan to 2,200,000, thereby assuring that
sufficient shares are available for future grants.
 
                                        9
<PAGE>   13
 
     BOARD OF DIRECTORS' ABILITY TO AMEND.  Recently revised securities
regulations have increased the ability of a company's board of directors to
amend employee benefit plans while maintaining the exempt status of option
grants under Section 16(b) of the Securities Exchange Act of 1934, as amended
(the "Exchange Act"). The proposed amendment and restatement of the Employee
Option Plan would permit the Board of Directors of the Company to materially
increase benefits to participants and to materially modify eligibility
requirements without receiving stockholder consent, so long as the amendments to
the Employee Option Plan would not materially adversely affect any outstanding
options. Stockholder approval would still be required, however, to increase the
number of shares of Common Stock subject to the Employee Option Plan. Under the
Employee Option Plan as the Board proposes it be amended and restated, approval
of the participants in the Employee Option Plan would still be required for any
amendments that would have a material adverse effect on outstanding options.
 
     CONFORMING TECHNICAL CHANGES.  The amendments proposed by the Board of
Directors include conforming certain terminology used in the Employee Option
Plan to the recently amended securities regulations.
 
     ELIMINATION OF CERTAIN QUALIFICATIONS.  The Employee Option Plan currently
contains certain qualifying references to the Company's then anticipated initial
public offering of Common Stock. The offering was consummated in July 1996,
thereby eliminating the necessity of these qualifications.
 
REQUIRED VOTE
 
     The proposed amendment and restatement of the Employee Option Plan requires
the affirmative vote of a majority of the shares present in person or
represented by proxy at the meeting and entitled to vote on the proposal. An
abstention will be counted as a vote against the amendment and restatement since
it is one less vote for approval. Broker non-votes will not affect the outcome
since they are not considered "shares present" for voting purposes.
 
     If the Board's proposal is approved by stockholders, the Employee Stock
Option Plan of APACHE Medical Systems, Inc. will be amended and restated
effective May 1, 1997.
 
     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE
FOR THIS PROPOSAL TO AMEND AND RESTATE THE EMPLOYEE STOCK OPTION PLAN OF APACHE
MEDICAL SYSTEMS, INC.
 
                          AMENDMENT AND RESTATEMENT OF
                    NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN
 
     The Board of Directors of the Company has adopted, and recommends to
stockholders for approval, the amendment and restatement of the APACHE Medical
Systems, Inc. Non-Employee Director Stock Option Plan (the "Director Option
Plan") to (i) allow the Board maximum flexibility in amending the Director
Option Plan as permitted by the recently revised securities regulations relating
to employee benefit plans and (ii) eliminate qualifications in the Director
Option Plan that relate to the Company's then anticipated initial public
offering of Common Stock, which has since been effected. The description of the
Director Option Plan set forth below is qualified in its entirety by reference
to the full text of the Amended and Restated Non-Employee Director Stock Option
Plan, which is attached as Appendix B to this proxy statement.
 
     GENERALLY.  The Director Option Plan as adopted by the Board of Directors
of the Company and approved by the Company's stockholders was originally
effective as of April 1, 1996. On January 1 of each calendar year, each
non-employee member of the Board of Directors of the Company will be granted an
option to purchase up to 2,500 shares of Common Stock under the Director Option
Plan. The Director Option Plan will continue until it is terminated by the Board
or until no Common Stock remains available for issuance.
 
     SHARES SUBJECT TO THE PLAN.  The Company has reserved 70,000 shares of
Common Stock for issuance under the Director Option Plan. As of March 10, 1997,
options on 12,500 shares of Common Stock were issued and outstanding under the
Director Option Plan.
 
                                       10
<PAGE>   14
 
     PLAN ADMINISTRATION.  The Director Option Plan is administered by the
Chairman of the Board of Directors and other employee members of the Board, if
any, selected by the Chairman. This Committee has the authority to construe and
interpret the Director Option Plan and to establish, amend or waive rules and
regulations for its administration. Options granted under the Director Option
Plan may be subject to such provisions as the Committee deems advisable and may
be amended by the Committee from time to time, provided that no amendment may
adversely affect the rights of an option holder without his or her consent.
 
     TERMS AND CONDITIONS OF OPTIONS.  All options granted under the Director
Option Plan are non-qualified stock options. The exercise price of each option
will be the fair market value of the stock underlying the option on the date of
grant. Each option will become fully vested and exercisable on the December 31
of the year in which the option is granted. Stock options granted under the
Director Option Plan may not be transferred other than by will or by the laws of
descent and distribution. Upon the occurrence of a Change of Control, as defined
in the Director Option Plan, all outstanding unvested options under the Director
Option Plan immediately vest.
 
     PLAN AMENDMENT.  The Director Option Plan currently provides that a
majority of the Board of Directors of the Company may, without further action of
the stockholders, terminate, alter, amend or suspend the Director Option Plan,
provided that the Board may not materially increase participants' benefits or
the number of shares issuable under the Director Option Plan, materially modify
the eligibility requirements for participation in the Director Option Plan, or
take any action that would cause the Director Option Plan to fail to comply with
certain applicable federal tax or securities laws. In addition, any action taken
by the Board may not materially and adversely affect any options outstanding
under the Director Option Plan without the consent of the participants.
Furthermore, the Board currently may not amend the Director Option Plan with
respect to the amount, price and timing of grants more than once every six
months, other than to comport with changes in law. A discussion of the Board's
proposal to increase its flexibility in amending the Director Option Plan as
permitted by the recently revised securities regulations is included below under
the caption "Proposed Amendment and Restatement of the Director Option
Plan -- Board of Directors' Ability to Amend."
 
     TAX CONSEQUENCES.  Certain federal income tax consequences are associated
with (i) the grant of a stock option under the Director Option Plan, (ii) the
exercise of such option and (iii) the disposition of shares received upon the
exercise of an option. The following description of tax consequences is based
upon present federal tax laws and regulations, but does not purport to be a
complete description of the federal income tax consequences applicable to a
participant under the Director Option Plan. Accordingly, information relating to
tax consequences is qualified in its entirety by reference to current tax laws.
 
     GRANT AND EXERCISE OF OPTIONS; DISPOSITION OF ACQUIRED SHARES.  The grant
of a non-qualified option to a participant will not be a taxable event so long
as the option does not have a readily ascertainable fair market value. Options
granted pursuant to the Director Option Plan should not have a readily
ascertainable fair market value because they are not actively traded on an
established securities market, are not transferable, are not immediately
exercisable in full upon grant and have more than a nominal exercise price.
Accordingly, the participant will not be subject to any income tax consequences
with respect to such option unless and until the option is exercised.
 
     Upon the exercise of a non-qualified stock option, the participant
generally must recognize ordinary compensation income equal to the "spread"
between the exercise price and the fair market value of the Common Stock on the
date of exercise. The amount and character of any gain or loss realized on a
subsequent disposition of Common Stock by the participant generally would depend
on, among other things, whether an election under Code Section 83(b) with
respect to such shares had been made, and the length of time such shares had
been held.
 
     WITHHOLDING TAXES.  The Company may condition the exercise of any option
under the Director Option Plan on the receipt of an amount sufficient to pay,
and will deduct from the compensation of a holder of an option under the
Director Option Plan, the amount of any tax required by any governmental
authority to be withheld and paid over by the Company to such governmental
authority for the account of such person with respect to such options and the
exercise thereof.
 
                                       11
<PAGE>   15
 
     COMPENSATION DEDUCTION.  To the extent compensation income is recognized by
a participant in connection with the exercise of a non-qualified stock option,
the Company generally will be entitled to a corresponding compensation deduction
(assuming the withholding requirements are satisfied).
 
     OUTSTANDING OPTIONS.  Each non-employee director of the Company will be
granted an option to purchase 2,500 shares for each year of service; however,
the number of years that such individuals will serve as directors of the Company
is not currently determinable. As of February 28, 1997, options to purchase
12,500 shares had been granted under the Director Option Plan to all current
directors who are not executive officers as a group. Each nominee for election
as a director (Mr. Connors, Mr. Hodson, Dr. Knaus, Mr. Lewin and Mr. Ziegler)
has been granted an option to purchase 2,500 shares. On March 19, 1997, the last
reported sale price of the Common Stock on the Nasdaq National Market was $6.125
per share.
 
PROPOSED AMENDMENT AND RESTATEMENT OF THE DIRECTOR OPTION PLAN
 
     BOARD OF DIRECTORS' ABILITY TO AMEND.  The proposed amendment and
restatement of the Director Option Plan would, in accordance with recently
revised securities regulations, permit the Board of Directors of the Company to
materially increase benefits to participants and to materially modify
eligibility requirements without receiving stockholder consent, so long as the
amendments to the Director Option Plan would not materially adversely affect any
outstanding options. Stockholder approval would still be required, however, to
increase the number of shares of Common Stock subject to the Director Option
Plan. In addition, the amendment and restatement would eliminate the restriction
that the Director Option Plan could only be amended once every six months. Under
the Director Option Plan as the Board proposes it be amended and restated,
approval of the participants in the Director Option Plan would still be required
for any amendments that would have a material adverse effect on outstanding
options.
 
     ELIMINATION OF CERTAIN QUALIFICATIONS.  The Director Option Plan currently
contains certain qualifying references to the Company's then anticipated initial
public offering of Common Stock. The offering was consummated in July 1996,
thereby eliminating the necessity of these qualifications.
 
REQUIRED VOTE
 
     The proposed amendment and restatement of the Director Option Plan requires
the affirmative vote of a majority of the shares present in person or
represented by proxy at the meeting and entitled to vote on the proposal. An

     If the Board's proposal is approved by stockholders, the APACHE Medical
Systems, Inc. Non-Employee Director Stock Option Plan will be amended and

     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE
FOR THIS PROPOSAL TO AMEND AND RESTATE THE APACHE MEDICAL SYSTEMS, INC.
NON-EMPLOYEE DIRECTOR STOCK OPTION PLAN.
 
                         RATIFICATION OF APPOINTMENT OF
                          INDEPENDENT PUBLIC AUDITORS
 
     The principal independent public accounting firm utilized by the Company
during the fiscal years ended December 31, 1995 and 1996 was KPMG Peat Marwick
LLP ("KPMG"), independent certified public accountants. The Company does not
anticipate that a representative of KPMG will attend the Annual Meeting.
 
     Following a review of the services provided by KPMG and of proposals from a
variety or other independent public accountants, management and the Audit
Committee recommended that the Board of Directors replace KPMG with Arthur
Andersen LLP ("Arthur Andersen") as soon as practicable following the completion
of the audit for fiscal year 1996. There were no disagreements with KPMG on any
matter of accounting principle or practice, of financial statement disclosure or
of auditing scope or procedure during
 
                                       12

fiscal years 1995 and 1996. KPMG's report on the financial statements of the
Company for fiscal years 1995 and 1996 contained no adverse opinion or
disclaimer of opinion and was not qualified or modified as to uncertainty, audit
scope or accounting principles. The Company provided notice to KPMG on February
14, 1997 of its dismissal and received a response from KPMG to the statements of
the Company in accordance with the requirements of Rule 304 of Regulation S-K of
the Securities and Exchange Commission. Neither the Company nor anyone on its
behalf has consulted with Arthur Andersen regarding (A) the application of
accounting principles to a specified transaction, either completed or proposed;
or the type of audit opinion that might be rendered on the Company's financial
statements, or (B) any matter that was either the subject of a disagreement or a
reportable event.
 
     The management of the Company and members of the Board of Directors have
discussed the Company's methods of operation with Arthur Andersen and are
satisfied as to the professional competence and integrity of Arthur Andersen.
The Board of Directors recommends that stockholders ratify the appointment of
Arthur Andersen, independent public accountants, to audit the accounts of the
Company for fiscal year 1997.
 
     Although the appointment of auditors is not required to be submitted to a
vote of stockholders, the Board of Directors believes that it is appropriate as
a matter of policy to request that the stockholders ratify the appointment. If
the stockholders should not ratify the appointment, the Audit Committee will
investigate the reasons for the stockholders' rejection and the Board of
Directors will reconsider the appointment.
 
REQUIRED VOTE
 
     The affirmative vote of a majority of the shares present in person or by
proxy and entitled to vote is required to ratify the appointment of Arthur
Andersen LLP as the Company's independent public auditors. An abstention will be
counted as a vote against the ratification of the appointment since it is one
less vote for approval. Broker non-votes will not affect the outcome since they
are not considered "shares present" for voting purposes.
 
     THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE
FOR RATIFICATION OF THE APPOINTMENT OF INDEPENDENT PUBLIC AUDITORS.

                      REPORT OF THE COMPENSATION COMMITTEE
                           OF THE BOARD OF DIRECTORS
 
EXECUTIVE COMPENSATION PHILOSOPHY
 
     The Compensation Committee of the Board is responsible for reviewing the
Company's executive compensation program and policies each year and determining
the compensation of the Company's executive officers. The Compensation
Committee's decisions are made within parameters established by the Company's
Board of Directors in the form of an overall executive compensation philosophy.
 
     The Company's compensation program and policies are designed to help the
Company attract, motivate and retain individuals of outstanding ability in key
positions in order to maximize return to stockholders. The primary objectives of
the Company's executive compensation program are to: (1) provide total
compensation opportunities that are competitive with opportunities provided to
executives of comparable companies in the decision support industry at
comparable levels of performance; (2) ensure that executive's total compensation
levels vary based on both the Company's short-term financial performance, and
growth in stockholder value over time; (3) focus and motivate executives on the
achievements of defined objectives; and (4) reward executives in accordance with
their relative contributions to achieving strategic milestones and upholding key
mission-related objectives.
 
     In designing and administering its executive compensation program, the
Company attempts to strike an appropriate balance among these objectives. It
believes that its executive compensation program includes elements which, taken
together, constitute a flexible and balanced method of establishing total
compensation for senior management. In Fall 1996, the Compensation Committee
undertook a major review of the Company's compensation program for senior
management. The focus of its review was to assess both the marketplace
competitiveness of APACHE's compensation practices and the degree to which the
amounts and design of the compensation programs support the strategic goals of
the Company. With a view to making the foregoing assessment, the Board directed
the Company to engage a national compensation consulting firm to develop
marketplace data and assess APACHE's practices against such data; assess the
overall effectiveness of the Company's pay program; assess APACHE's compensation
philosophy and its alignment with its strategic business needs; and finally,
develop recommendations regarding compensation levels, incentive pay programs
and its ongoing compensation philosophy. The market analysis included data from
the following sectors: decision support, information systems, investor owned
healthcare companies, combined profit and not-for-profit healthcare companies
and all industrial companies.
 
     Based upon a previous review and the recommendations of its consultants,
the Committee had identified compensation ranges based on the 50th percentile of
competitive data for similarly sized decision support
 
                                       17

organizations. The Committee had concluded that the Company's most direct
competitors for executive talent are in the decision support industry and,
accordingly, although it reviewed information from all of the sectors identified
above, it principally compared its actions to a self-selected group of decision
support companies of comparable size (the "Compensation Comparable Group") and
used the other data compiled by its consultants as a reference point. The
Compensation Comparable Group is similar, but not identical to, the peer
performance group used in calculating the cumulative total return discussed
under "Company Performance" below.
 
     The Company's executive compensation programs, which contain no special
perquisites, consist of three principle elements: base salary, short-term
incentive cash payments and long-term stock options. Since the compensation
program was adopted during 1996, the implementation of the base compensation
part of the executive compensation program also took place during 1996.
 
BASE COMPENSATION
 
     Generally, in establishing compensation the Committee believes that
positions are competitively paid if the executive's salary falls within 20% of
the 50th percentile for base salary. The Committee reviews updated competitive
salary and total compensation levels for executive staff. Individual adjustments
are determined within the total executive compensation budget as approved by the
Committee and are based upon individual achievement and contribution. Salary
decisions are made as part of the Company's structured annual review process and
are recommended to the Committee by the Chairman and Chief Executive Officer.
 
SHORT-TERM INCENTIVE COMPENSATION
 
     The Company's compensation philosophy emphasizes incentive pay to leverage
both individual and organizational performance and to raise the Company's total
compensation position in the marketplace. The Company's short-term incentive
compensation program rewards executives for accomplishing annual financial,
operational, and individual objectives. The program provides varied award
opportunities that correspond to each participant's level of responsibility and
influence on strategic initiatives of the Company. The annual incentive program
is funded only if specific financial goals are achieved at threshold levels. In
1996, executives participated in the incentive compensation program at targeted
levels (as percentage of base salaries) ranging between 25.2% and 36.4%.
Participants in the incentive compensation program receive bonus payments that
include awards for financial, operational and individual achievement of goals.
The Committee assigned levels of threshold, target and maximum bonuses with
corresponding performance expectations for each category of participants. For
1996, the Committee established weighted performance measures based upon
financial (50%); operational (25%); and individual (25%) objectives. The average
bonus paid to eligible executives for 1996 was 31.3% of base salaries,
representing 85% to 95% achievement of the three objectives.
 
LONG-TERM INCENTIVE COMPENSATION
 
     The Company's stockholders approved adoption of a stock option plan in
1996, which is designed to reward employees for long-term growth consistent with
stockholder return. In 1996, senior management was awarded stock options in
amounts designed to deliver a percentage of their base salaries over the term of
the stock option. Option values for senior management are targeted at 100% of
market value. The ultimate value of the long-term incentive compensation awards
will be determined by the actual performance of the Company's stock price over
time.
 
CEO COMPENSATION
 
     The Committee established the compensation of Gerald E. Bisbee, Jr., Ph.D.,
Chairman and Chief Executive Officer of the Company, mid-way through 1996, using
the above criteria. Dr. Bisbee's salary was determined based on the Committee's
overall assessment of Dr. Bisbee's performance and competitive market data on
salary levels within the Compensation Comparable Group. Dr. Bisbee's performance
was reviewed with a view to his accomplishment of certain goals relating to
long-term profitability and short and long-term growth. Dr. Bisbee's aggregate
salary in 1996 was increased 18.3% over 1995 levels. No bonus was paid in
 
                                       18
<PAGE>   22
 
fiscal year 1996. The CEO was paid a cash bonus in 1997 with respect to
performance in the year ended December 31, 1996. Incentive compensation for Dr.
Bisbee is based upon achievement of Company-wide financial and operating
performance and achievement of individual goals.
 
COMPENSATION DEDUCTIBILITY
 
     Section 162(m) of the Internal Revenue Code of 1986, as amended (the
"Code"), imposes a limit on tax deductions for annual compensation in excess of
one million dollars paid by a corporation to its chief executive officer and the
other four most highly compensated executive officers of the corporation. This
provision excludes certain forms of "performance based compensation" from the
compensation taken into account for purposes of the limit. The Committee
believes that it has structured its current compensation programs in a manner to
preserve full deductibility to the Company of executive compensation under the
Code. The Committee will continue to assess the impact of Section 162(m) of the
Code on its compensation practices and determine what further action, if any, is
appropriate.
 
     It is the opinion of the Committee that the aforementioned compensation
structures provide features that properly align the Company's executive
compensation with corporate performance and the interests of its stockholders
and offer competitive opportunities in the marketplace.

     The following graph compares the cumulative total stockholder return on the
Common Stock of APACHE Medical Systems, Inc. from June 28, 1996 (the date the
Common Stock was first offered to the public at an initial public offering price
of $12.00 per share) through December 31, 1996 with the cumulative total return
on the NASDAQ Stock Market - U.S. and the cumulative total return on the stock
of a group of public companies in the healthcare information business (the "Peer
Group"). The Peer Group, which was selected by the Company, is comprised of:
HCIA Inc.; HPR Inc.; Impath Laboratories Inc.; Mecon, Inc.; Oacis Health Care
Holdings, Corp.; Summit Medical Systems, Inc.; Transition Systems Inc; and
Vitalcom Inc. The Company did not pay any dividends during this period. The
NASDAQ Stock Market - U.S. and the stock prices of the Companies in the Peer

                                       A-2
<PAGE>   29
 
shall have absolute discretion to determine, within the limits of the express
provisions of the Plan, those Participants to whom and the time or times at
which Options shall be granted. The Committee shall also determine, within the
limits of the express provisions of the Plan, the number of shares to be subject
to each Option, the duration of each Option, the exercise price under each
Option, the time or times within which (during the term of the Option) all or
portions of each Option may become vested and exercisable, and whether an Option
shall be an Incentive Stock Option, a Nonqualified Stock Option or a combination
thereof. In making such determination, the Committee may take into account the
nature of the services rendered by the Participant, his or her present and
potential contributions to the Company's success and such other factors as the
Committee in its discretion shall deem relevant.
 
     Notwithstanding the foregoing, no Incentive Stock Option shall be granted
to any Participant who is not an employee of the Company and no non-employee
member of the Board shall be eligible to receive any new Option grant hereunder.
 
     SECTION 6.  TERMS AND CONDITIONS OF OPTIONS.
 
     Each Option granted under the Plan shall be evidenced by an agreement, in a
form approved by the Committee, which shall be subject to the following express
terms and conditions and to such other terms and conditions as the Committee may
deem appropriate:
 
     (a) Option Period.  Each Option agreement shall specify the period for
which the Option thereunder is granted (which, in the case of Incentive Stock
Options, shall not exceed ten years from the date of grant) and shall provide
that the Option shall expire at the end of such period.
 
     (b) Exercise Price.  The per share exercise price of each Option shall be
determined by the Committee at the time the Option is granted, and, in the case
of Incentive Stock Options, shall not be less than the Fair Market Value of
Common Stock on the date the Option is granted.
 
     (c) Vesting of Options.  No part of any Option may be exercised until the
Participant shall have satisfied the vesting conditions (i.e., such as remaining
in the employ of the Company for a certain period of time), if any, as the
Committee may specify in the applicable Option agreement. Subject to the
provisions of Section 6(e), any Option may be exercised, to the extent
exercisable by its terms, at such time or times as may be determined by the
Committee.
 
     (d) Payment.  The exercise price of an Option shall be paid in full at the
time of exercise (i) in cash, (ii) through the surrender of previously-acquired
shares of Common Stock having a Fair Market Value equal to the exercise price of
the Option, (iii) through the withholding by the Company (at the election of the
Participant) of shares of Common Stock having a Fair Market Value equal to the
exercise price or (iv) by a combination of (i), (ii) and (iii).
 
     (e) Other Rules Applicable to Incentive Stock Options.
 
          (i) Grant Period.  Consistent with Section 9, an Incentive Stock
     Option must be granted within ten years of the date this Plan is adopted
     (i.e., the Effective Date, as defined in Section 13) or the date the Plan
     is approved by the stockholders of the Company, whichever is earlier.
 
          (ii) Ten Percent Owner.  If a Participant, on the date that an
     Incentive Stock Option is granted, owns, directly or indirectly, within the
     meaning of Section 424(d) of the Code, stock representing more than 10% of
     the voting power of all classes of stock of the Company, then the exercise
     price per share shall in no instance be less than 110% of the Fair Market
     Value per share of Common Stock at the time the Incentive Stock Option is
     granted, and no Incentive Stock Option shall be exercisable by such
     Participant after the expiration of five years from the date it is granted.
 
          (iii) Employee Status.  To retain favorable Incentive Stock Option tax
     treatment, the Option holder must at all times from the date the Option is
     granted through a date that is no more than three months prior to the date
     it is exercised (or no more than one year prior to the date it is
     exercised, where the Participant's termination of employment is due to
     death or Disability) remain an employee of the
 
                                       A-3
<PAGE>   30
 
     Company. For this purpose, authorized leaves of absence shall not be deemed
     to sever the employment relationship.
 
          (iv) Limitations on Dispositions.  To retain favorable Incentive Stock
     Option tax treatment, Common Stock received upon the exercise of an
     Incentive Stock Option may not be disposed of prior to the later of two
     years from the date the Incentive Stock Option is granted or one year from
     the date the shares of Common Stock are transferred to the Participant upon
     exercise of the Incentive Stock Option.
 
          (v) Value of Shares.  The aggregate Fair Market Value (determined at
     the date of grant) of the Incentive Stock Options exercisable for the first
     time by a Participant during any calendar year shall not exceed $100,000 or
     any other limit imposed by the Code.
 
     (f) Limit on the Exercisability of all Options.  No Option granted under
this Plan may become exercisable prior to six months following the date it is
granted or six months after stockholders approve the Plan, whichever date is
later.
 
     SECTION 7.  TREATMENT OF OPTIONS UPON TERMINATION.
 
     (a) Termination due to Disability or Death.  Upon the termination of
employment of an employee Participant or upon the termination of the consulting
or advisor relationship of a non-employee Participant by reason of Disability or
death, such Participant's Options shall become or remain fully vested and shall
be exercisable by such Participant (or, in the case of death, by his or her
estate) for not later than the earlier of one year after the termination date or
the expiration of the term of the Options.
 
     (b) Termination Other than For Cause.  Upon the termination of employment
of an employee Participant or upon the termination of the consulting or advisor
relationship of a non-employee Participant for any reason other than for Cause
(as defined in Section 7(c)), Disability or death, such Participant's Options
(to the extent vested prior to such termination) may be exercised by such
Participant during the six-month period commencing on the date of termination,
but not later than the expiration of the term of the Options. If a Participant
dies during such six-month period, his or her estate may exercise the Options
(to the extent such Options were vested and exercisable prior to death), but not
later than the earlier of one year after the date of death or the expiration of
the term of the Options. Notwithstanding the foregoing, to retain favorable
Incentive Stock Option tax treatment, Incentive Stock Options must be exercised
within three months of the Participant's termination of employment.
 
     (c) Termination for Cause.  Upon termination of the employment of an
employee Participant or upon the termination of the consulting or advisor
relationship of a non-employee Participant for Cause (as defined below), the
Participant's right to exercise his or her Options shall terminate at the time
notice of termination is given by the Company to such Participant. For purposes
of this provision, substantial cause shall include:
 
          (i) The commission of an action against or in derogation of the
     interests of the Company which constitutes an act of fraud, dishonesty or
     moral turpitude or which, if proven in a court of law, would constitute a
     violation of a criminal code or similar law;
 
          (ii) A material breach of any material duty or obligation imposed upon
     the Participant by the Company;
 
          (iii) Divulging the Company's confidential information; or
 
          (iv) The performance of any similar action that the Committee, in its
     sole discretion, may deem to be sufficiently injurious to the interests of
     the Company so as to constitute substantial cause for termination.
 
     SECTION 8.  ADJUSTMENT PROVISIONS.
 
     In the event of a stock split, stock dividend, recapitalization,
reclassification or combination of shares, merger, sale of assets or similar
event, the Committee shall adjust equitably (a) the number and class of shares
or other securities that are reserved for issuance under the Plan, (b) the
number and class of shares or other securities that are subject to outstanding
Options, and (c) the appropriate Fair Market Value and other
 
                                       A-4
<PAGE>   31
 
price determinations applicable to Options. The Committee shall make all
determinations under this Section 8, and all such determinations shall be
conclusive and binding.
 
     SECTION 9.  TERM OF PLAN.
 
     The Plan shall be deemed adopted and shall become effective on the date it
is approved by the stockholders of the Company and shall continue until April 1,
2006, or, if earlier, upon termination of the Plan by the Board or until no
Common Stock remains available for issuance under Section 4.
 
     SECTION 10.  CHANGE IN CONTROL.
 
     In the event of a Change in Control, all outstanding Options shall fully
vest in each Participant. The Committee, in its discretion, may also provide in
any Option agreement for adjustment of certain terms of such Option upon the
occurrence of a Change in Control.
 
     SECTION 11.  GENERAL PROVISIONS.
 
     (a) Employment.  Nothing in the Plan or in any related instrument shall
confer upon any employee Participant or other employee any right to continue in
the employ of the Company or shall affect the right of the Company to terminate
the employment of any employee Participant or other employee with or without
cause.
 
     (b) Legality of Issuance of Shares.  No Common Stock shall be issued
pursuant to the exercise of an Option unless and until all legal requirements
applicable to such issuance have been satisfied.
 
     (c) Ownership of Common Stock Allocated to Plan.  No Participant
(individually or as a member of a group), and no beneficiary or other person
claiming under or through such Participant, shall have any right, title or
interest in or to any Common Stock allocated or reserved for purposes of the
Plan or subject to any Option, except as to shares of Common Stock, if any, as
shall have been issued to such Participant or beneficiary.
 
     (d) Governing Law.  The Plan, and all agreements hereunder, shall be
construed in accordance with and governed by the laws of the State of Virginia.
 
     (e) Withholding of Taxes.  The Company may withhold, or allow a Participant
to remit to the Company, any Federal, state or local taxes required by law to be
withheld with respect to any event giving rise to income tax liability with
respect to an Option. In order to satisfy all or any portion of such income tax
liability, a Participant may elect to surrender Common Stock previously acquired
by the Participant or to have the Company withhold Common Stock that would
otherwise have been issued to the Participant pursuant to the exercise of an
Option, the number of shares of such withheld or surrendered Common Stock to be
sufficient to satisfy all or a portion of the income tax liability that arises
upon the event giving rise to income tax liability with respect to an Option.
 
     (f) Nontransferability.  During the lifetime of a Participant, any Option
granted to him or her shall be exercisable only by him or her or by his or her
guardian or legal representative. No Option shall be assignable or transferable,
except by will or by the laws of descent and distribution, and no option shall
be subjected to any encumbrance, pledge or charge of any nature.
 
     SECTION 12.  AMENDMENT OR DISCONTINUANCE OF THE PLAN.
 
     The Board, acting by a majority of its members, without further action on
the part of the stockholders, may from time to time alter, amend or suspend the
Plan or any Option granted hereunder or may at any time terminate the Plan;
provided, however, that the Board may not materially increase the number of
shares of Common Stock subject to the Plan (except as provided in Section 8
hereof); and provided further that no such action shall materially and adversely
affect any outstanding Options without the consent of the respective
Participants.

     (e) Payment.  The exercise price of an Option shall be paid in full at the

the extent vested prior to such termination) may be exercised by such
Participant during the six-month period commencing on the date of termination,

the term of the Options.
 
     (c) Termination for Cause.  Upon termination of a Participant's membership

cause shall include:

     interests of the Company which constitutes an act of fraud, dishonesty or
     moral turpitude or which, if proven in a court of law, would constitute a
     violation of a criminal code or similar law;

     the Participant by the Company;
 
          (iii) Divulging the Company's confidential information; or

     sole discretion, may deem to be sufficiently injurious to the interests of
     the Company so as to constitute substantial cause for termination.
 
     SECTION 8.  ADJUSTMENT PROVISIONS.
 
     In the event of a stock split, stock dividend, recapitalization,
reclassification or combination of shares, merger, sale of assets or similar
event, the Committee shall adjust equitably (a) the number and class of shares
or other securities that are reserved for issuance under the Plan, (b) the

determinations applicable to Options. The Committee shall make all
determinations under this Section 8, and all such determinations shall be
conclusive and binding.
 
     SECTION 9.  TERM OF PLAN.

interest in or to any Common Stock allocated or reserved for purposes of the
Plan or subject to any Option, except as to shares of Common Stock, if any, as
shall have been issued to such Participant or beneficiary.

otherwise have been issued to the Participant pursuant to the exercise of an
Option, the number of shares of such withheld or surrendered Common Stock to be
sufficient to satisfy all or a portion of the income tax liability that arises
