I.      PURPOSE AND SCOPE

The purposes of this Medical Advisory Systems, Inc. Amended and Restated
Employee and Director Stock Option Plan (the "Plan") are to encourage stock
ownership by Employees of Medical Advisory Systems, Inc., a Delaware
corporation, or any of its Subsidiaries (collectively the "Company") and to
assist the Company in attracting and retaining key personnel through the grant
of options to purchase shares of the Company's common stock.

Board, and which shall be composed of three members of the Board.

"CODE" shall mean the Internal Revenue Code of 1986, as amended.

"EMPLOYEE" shall mean officers, directors, employees, advisors and consultants
who render services to the Company.

"OPTION" shall mean a right to purchase Stock, granted pursuant to the Plan.

Option, as determined in Section V below.

Plan.

III.    STOCK TO BE OPTIONED

Subject to the provisions of Section XVII herein, the maximum number of shares
of Stock that may be optioned or sold under the Plan is 1,650,000 shares. Such
shares may be authorized but unissued shares of the Stock of the Company.

IV.     ADMINISTRATION

The Committee shall administer the Plan. Two members of the Committee shall
constitute a quorum for the transaction of business. The Committee shall be
responsible to the Board for the operation of the Plan, and shall make
recommendations to the Board with respect to participation in the Plan by
Employees and with respect to the extent of that participation. The
interpretation and construction of any provision of the

<PAGE>   2

Plan by the Committee shall be final, unless otherwise determined by the Board.
No member of the Board or the Committee shall be liable for any action or
determination made by him in good faith.

The Board, upon recommendation of the Committee, may grant Options to any
Employee upon such terms and conditions as it determines appropriate, including,
but not limited to, provisions regarding vesting of Options granted, and
covenants not to compete and confidentiality requirements. Options may be
awarded by the Board at any time and from time to time to new Participants, or
to a greater or lesser number of Participants, and may include or exclude
previous Participants, as the Board, upon recommendation by the Committee, shall
determine. Options granted at different times need not contain similar
provisions and no grant of Options shall be effective until such time as the
Employee enters into the Option Agreement presented by the Board in conjunction
with such grant of Options, by executing and returning such agreement to the
Board.

V.      OPTION PRICE

The purchase price for Stock under each Option shall not be less than the fair
market value of the Stock at the close of business on the date the Option is
granted, but in no event less than the par value of the Stock. For purposes of
this Section, "fair market value" shall be the average of the highest and lowest
price for a share of Stock, as quoted on the American Stock Exchange (or if the
Stock is not then traded on such Exchange, on any other exchange or market
through which the Stock is traded) on the last trading date immediately
preceding the date of the grant.

VI.     EXERCISE OF STOCK OPTIONS

A Stock Option shall be exercised by a Participant or other person authorized
under this Plan to exercise such Option by the provision of written notice, on a
form approved by the Committee, indicating the person's intention to exercise
same, accompanied by full payment of the purchase price. Said purchase price
shall be paid with cash or certified check, or with a surrender of Stock having
a fair market value on the date of exercise equal to that portion of the
purchase price for which payment in cash or by certified check is not made. In
the event that Stock is surrendered upon exercise of an Option, certificates
evidencing the shares to be so used shall be delivered to the Company and shall
be duly endorsed or accompanied by duly executed stock powers to transfer the
same to the Company; provided, however, that such payment in Stock instead of
cash or cashier's check shall not be effective and shall be rejected by the
Company if (a) the Company is then prohibited from purchasing shares of the
class of the stock thus tendered to it, or (b) the right or power of the person
exercising the Option to deliver such shares in payment of the purchase price is
subject to restrictions (determined as of the date such Stock is tendered),
including, but not limited to, the prior interest of any other person as
indicated by legends upon the certificate(s) or known to the Company. If the
Company rejects the payment in stock, the tendered notice of exercise shall not
be effective hereunder unless, after being notified of such rejection, the
person exercising the Option pays the purchase price in an acceptable form. The
Company shall be entitled, at its option, to return those shares of Stock as
part of the shares for which the Option was exercised rather than re-issuing new
shares.

The Company shall have the right to require a Participant, or any other person
authorized to exercise Options under this Plan, to pay to the Company the amount
of any taxes which the Company is required to withhold as a result of the
exercise of said Option.

VII.    TERMS AND CONDITIONS OF OPTIONS

Options granted pursuant to the Plan shall be authorized by the Board and shall
be evidenced by agreements in such form as the Board, upon recommendation of the
Committee, shall from time to time approve. Such Agreements shall include a
provision that during the period in which a Participant is employed by the
Company, Participant shall be limited in trading shares of the Company acquired

<PAGE>   3

through exercise of any Option in accordance with the Company's then current
policy governing trading in the shares of the Company by Officers and Directors.

VIII.   EMPLOYMENT AGREEMENT

The Board may, in its discretion, include in any Option granted under the Plan a
condition that the Participant shall agree to remain in the employ of, and to
render services to, the Company or any of its Subsidiaries for a period of time
(specified in the agreement) following the date the Option is granted. However,
no such agreement shall impose any obligation upon the Company to employ the
Participant for any period of time.

IX.     TIME AND METHOD OF PAYMENT

The Option Price shall be paid in full either in cash or under a cash-less
option provision (depending on the form of Option Agreement granted to the
Participant) at the time an Option is exercised under the Plan. Otherwise, an
exercise of any Option granted under the Plan shall be invalid and of no effect.
Promptly after the exercise of an Option and the payment of the full Option
Price, the Participant shall be entitled to the issuance of a stock certificate
evidencing his ownership of such Stock. Participant shall have none of the
rights of a shareholder until shares are issued to him, and no adjustment will
be made for dividends or other rights for which the record date is prior to the
date such stock certificate is issued.

X.      NUMBER OF SHARES

Each Option shall state the total number of shares of Stock to which it pertains
and the number of Shares to which a participant is entitled under an Option
agreement.

XI.     OPTION PERIOD, AND LIMITATIONS ON EXERCISE OF OPTIONS

The Board may, in its discretion, provide that an Option may not be exercised in
whole or in part for any period or periods of time specified in the Option
agreement. Except as provided in the Option agreement or otherwise herein, an
Option maybe exercised in whole or in part at any time during its term. No
Option may be exercised after the expiration of ten (10) years from the date it
is granted. No Option may be exercised for a fractional share of Stock.

XII.    TERMINATION OF EMPLOYMENT

Except as provided in Section XIII below, if a Participant ceases to be employed
by the Company, his Options shall terminate immediately; provided, however, that
the Participant may, at any time within three months after such cessation of
employment, exercise his Options to the extent that he was entitled to exercise
them on the date of cessation of employment, but in no event shall any option be
exercisable more than ten (10) years from the date it was granted.

XIII.   RIGHTS IN THE EVENT OF DEATH

If a Participant dies while employed by the Company, or within three months
after having retired with the consent of the Company, and without having fully
exercised his options, the executors or administrators, or legatees or heirs, of
his estate shall have the right to exercise such Options and to the extent that
such deceased Participant was entitled to exercise said Options on the date of
his death; provided, however, that in no event shall the Options be exercisable
more than ten (10) years from the date they were granted.

XIV.    NO OBLIGATIONS TO EXERCISE OPTION

The granting of an Option shall impose no obligation upon the Participant to
exercise such Option.

<PAGE>   4

XV.     NONASSIGNABILITY

Options shall not be transferable other than by will or by the law of descent
and distribution, and during a Participant's lifetime shall be exercisable only
by such Participant.

XVI.    LOSS OF RIGHT TO EXERCISE OPTIONS

A Participant or other person entitled to exercise Options under this Plan shall
forfeit such rights if the Participant violates a confidentiality agreement or
covenant not to compete with the Company whether contained within individual
Stock Option Agreements entered into between the Participant and the Company by
separate instrument.

XVII.   EFFECT OF CHANGE IN STOCK SUBJECT TO THE PLAN

The aggregate number of shares of Stock available for Options under the Plan,
the shares subject to any Option, the price per share, shall all be
proportionately adjusted for any increase or decrease in the number of issued
shares of Stock subsequent to the effective date of the Plan resulting from (1)
a subdivision or consolidation of shares or any other capital adjustment, (2)
the payment of a stock dividend, or (3) other increase or decrease in such
shares effected without receipt of consideration by the Company, if the Company
shall be the surviving corporation in any merger or consolidation, any Option
shall pertain, apply and relate to the securities to which a holder of the
number of shares of Stock subject to the Option would have been entitled after
the merger or consolidation.

Upon dissolution or liquidation of the Company, or upon a merger or
consolidation in which the Company is not the surviving corporation, all Options
outstanding under the Plan shall terminate; provided, however, that each
Participant (and each other person entitled under this Plan to exercise an
Option) shall have the right, immediately prior to such dissolution or
liquidation, or such merger or consolidation, to exercise such Participant's
Options in whole or in part, but only to the extent that such Options are
otherwise exercisable under the terms of this Plan.

XVIII.  AMENDMENT AND TERMINATION

The Board, by resolution, may terminate, amend, or revise the Plan with respect
to any shares as to which Options have not been granted. Neither the Board nor
the Committee may, without the consent of the holder of an Option, alter or
impair any Option previously granted under the Plan, except as authorized
herein. Unless sooner terminated, the Plan shall remain in effect for a period
of 10 years from the date of this amended and restated Plan's adoption by the
Board. Termination of the Plan shall not affect any Option previously granted.

XIX.    COMPLIANCE WITH LAW AND APPROVAL OF REGULATORY BODY

No Option shall be exercisable and no Stock will be delivered under this Plan
except in compliance with all applicable federal and state laws and regulations,
including, without limitation, compliance with all applicable withholding tax
requirements, if any, and with the rules of all domestic stock exchanges on
which the Stock may be listed. Any stock certificates issued to evidence the
Stock as to which an Option is exercised may bear such legends and statements as
the Company shall deem advisable to assure compliance with federal and state
laws and regulations; the Company may, if it deems appropriate, condition its
grant of any Options hereunder upon receipt of the following investment
representation from the Participant or other person authorized to exercise such
Options under this Plan:

                "I agree that any Stock of Medical Advisory Systems, Inc. which
                I may acquire by virtue of this Stock Option shall be acquired
                for investment

<PAGE>   5

                purposes only and not with a view to distribution or resale, and
                may not be transferred, sold, assigned, pledged, hypothecated or
                otherwise disposed of by me unless (i) a registration statement
                or post-effective amendment to a registration statement under
                the Securities Act of 1933, as amended, with respect to said
                Stock has become effective so as to permit the sale or other
                disposition of said shares by me; or (ii) there is presented to
                Medical Advisory Systems, Inc. an opinion of counsel
                satisfactory to Medical Advisory Systems, Inc. to the effect
                that the sale or other proposed disposition of said Stock by me
                may lawfully be made otherwise than pursuant to an effective
                registration statement or post-effective amendment to a
                registration statement relating to the said Stock under the
                Securities Act of 1933, as amended."

No Option shall be exercisable, and no stock will be delivered under this Plan,
until the Company has obtained such consent or approval from the regulatory
body, federal or state, having jurisdiction over such matters as the Company may
deem advisable. In the case of the exercise of an Option by someone other than
the Participant as permitted herein, the Company may require reasonable evidence
as to the ownership of such Option and may require such consents and releases of
taxing authorities as the Committee may deem advisable.

XX.     PRESERVATION OF SHARES OF STOCK

The Company, during the term of this Plan, will at all times reserve and keep
available and will seek or obtain from any regulatory body having jurisdiction
any requisite authority necessary to issue and to sell, the number of Shares of
Stock that shall be sufficient to satisfy the requirements of this Plan. The
inability of the Company to obtain from any regulatory body having jurisdiction
the authority deemed necessary by counsel for the Company for the lawful
issuance and sale of its stock hereunder shall relieve the Company of any
liability in respect of the failure to issue or sell Stock as to which the
requisite authority has not been obtained.

XXI.    EFFECTIVE DATE OF PLAN

The Plan was originally effective as of June 21, 1993; the date the Plan was
approved by the Board of Directors. The terms of this amended and restated Plan

otherwise directed by the Board. From time to time the Board may increase the
size of the Committee and appoint additional members thereof, remove members
(with or without cause), and appoint new members in substitution therefor, fill
vacancies however caused and remove all members of the Committee, and thereafter
directly administer the Plan. Notwithstanding anything in this Section 4 to the
contrary, at any time the Board or the Committee may delegate to a committee of
one or more members of the Board who are not Non-Employee Directors the
authority to grant Stock Awards to all Employees and Consultants who are not
then subject to Section 16 of the Exchange Act.

            (b) POWERS OF THE BOARD. Subject to the provisions of the Plan, the
Board shall have the authority to administer, interpret and amend the Plan and
the Stock Awards so long as no such exercise of authority is directly
contradictory to the terms and conditions of the Plan. The Board's authority
shall include the following powers: (i) to grant Stock Awards under the Plan;
provided, however, that only Nonstatutory Stock Options may be granted under the
Plan; (ii) to determine, upon review of relevant information and in accordance
with subsection 2(m) of the Plan, the Fair Market Value of the Common Stock;
(iii) to determine the exercise price per share of Options to be granted, which
exercise price shall be determined in accordance with subsection 7(b) of the
Plan; (iv) to determine the Employees or Consultants to whom, and the time or
times at which, Stock Awards shall be granted and the number of Shares to be
represented by each Stock Award, provided that no Stock Award may be granted to
a person who is not either an Employee or a Consultant; (v) to interpret the
Plan and any Stock Award Agreement; (vi) to prescribe, amend and rescind rules
and regulations relating to the Plan; (vii) to determine the terms and
provisions of each Stock Award granted (which need not be identical) in
accordance with the Plan, and, with the consent of the holder thereof with
respect to any adverse change, modify or amend each Stock Award; (viii) to
accelerate or defer (the latter with the consent of the holder thereof) the
exercise date and vesting schedule of any Stock Award; (ix) to authorize any
person to execute on behalf of the Company any instrument required to effectuate
the grant of a Stock Award previously granted by the Board or to carry out any
other task related to the administration of the Plan; (x) to amend, suspend or
terminate the Plan in accordance with Section 12 of the Plan; and (xi) to make
all other determinations deemed by the Board to be necessary or advisable or
appropriate for the administration of the Plan. Any and all of these powers, as
well as the Board's overall authority to administer the Plan, may be exercised
in the Board's sole discretion.

            (c) EFFECT OF BOARD'S DECISION. All decisions, determinations and
interpretations of the Board shall be final and binding on all Participants and
any other holders of any Stock Awards granted under the Plan.

<PAGE>   5

         5. ELIGIBILITY.

            (a) Stock Awards may be granted only to Employees (including
Officers) or Consultants as defined in Section 2 hereof. An Employee or
Consultant who has been granted a Stock Award, if he or she remains eligible,
may be granted an additional Stock Award or Stock Awards. Notwithstanding the
foregoing, the aggregate number of shares of Common Stock issued pursuant to
Stock Awards granted to Officers cannot exceed forty percent (40%) of the number
of shares of Common Stock reserved for issuance under the Plan as determined at
the time of each issuance to an Officer, except that there shall be excluded
from this calculation shares of Common Stock issued to Officers not previously
employed by the Company pursuant to Stock Awards granted as an inducement
essential to such individuals entering into employment contracts with the
Company.

            (b) Stock Awards may not be granted to Consultants who are not
natural persons unless the Company determines both (i) that such grant (A) shall
be registered in a manner other than on the Form S-8 Registration Statement
under the Securities Act (e.g., on a Form S-3 Registration Statement) or (B)
does not require registration under the Securities Act in order to comply with
the requirements of the Securities Act, if applicable, and (ii) that such grant
complies with the securities laws of all other relevant jurisdictions.

            (c) The Plan shall not confer upon any Participant any right with
respect to continuation of employment or consultancy by the Company, nor shall
it interfere in any way with the Participant's right or the Company's right to
terminate the Participant's employment at any time, for any reason or no reason,
with or without cause, or to terminate the Participant's consultancy pursuant to
the terms of the Consultant's agreement with the Company.

         6. TERM OF THE PLAN.

            The Plan shall become effective upon its adoption by the Board of
Directors. It shall continue in effect until terminated under Section 12 of the
Plan.

         7. OPTION PROVISIONS.

            (a) TERM OF OPTION. The term of each Option shall be ten (10) years
from the date of grant thereof or such shorter term as may be provided in the
Option Agreement.

            (b) EXERCISE PRICE, CONSIDERATION AND VESTING.

                (i) EXERCISE PRICE. The exercise price of each Option shall be
not less than 100% of the Fair Market Value of the Common Stock subject to the
Option on the date of grant.

                (ii) CONSIDERATION. The consideration to be paid for the Shares
to be issued upon exercise of an Option shall be paid, to the extent permitted
by applicable statutes and regulations, as follows: (i) in cash (or by check),
or (ii) at the discretion of the Board, as determined either at the time of the
grant of the Option or at any time thereafter at or before the time the Option
is exercised: (A) by delivery to the Company of other Common Stock of the
Company (which has either been held for the period required to avoid a charge to
the Company's

                                       5

reported earnings (generally six months) or that was not acquired, directly or
indirectly from the Company, that are owned free and clear of any liens, claims,
encumbrances or security interests, and that are valued at Fair Market Value on
the date of exercise), or (B) in any other form of legal consideration that may
be acceptable to the Board, or (iii) any combination thereof.

                (iii) VESTING. The total number of Shares subject to an Option
may, but need not, become exercisable in periodic installments (which may, but
need not, be equal). The Option Agreement may provide that, from time to time
during each of such installment periods, the Option may become exercisable
("vest") with respect to some or all of the Shares allotted to that period, and
may be exercised with respect to some or all of the Shares allotted to such
period and/or any prior period as to which the Option became vested but was not
fully exercised. The Option may be subject to such other terms and conditions on
the time or times when it may be exercised (which may be based on performance or
other criteria) as the Board may deem appropriate. The provisions of this
subsection 7(b) are subject to any Option provisions governing the minimum
number of Shares as to which an Option may be exercised.

            (c) EXERCISE OF OPTION.

                (i) PROCEDURE FOR EXERCISE; RIGHTS AS A STOCKHOLDER. Any Option
granted hereunder shall be exercisable at such times and under such conditions
as determined by the Board, including performance criteria with respect to the
Company and/or the Optionholder, and as shall be permissible under the terms of
the Plan.

                (ii) An Option may not be exercised for a fraction of a Share.

                (iii) An Option shall be deemed to be exercised when written
notice of such exercise has been given to the Company in accordance with the
terms of the Option by the person entitled to exercise the Option and full
payment for the Shares with respect to which the Option is exercised has been
received by the Company. Full payment may, as authorized by the Board, consist
of any consideration and method of payment allowable under subsection 7(b) of
the Plan. Until the issuance (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company) of the
stock certificate evidencing such Shares, no right to vote or receive dividends
or any other rights as a stockholder shall exist with respect to the Shares,
notwithstanding the exercise of the Option. No adjustment will be made (for
example, for a dividend or other right for which the record date is prior to the
date the stock certificate is issued), except as provided in Section 9 of the
Plan.

                (iv) Exercise of an Option in any manner shall result in a
decrease in the number of Shares that thereafter may be issued, for purposes of
the Plan and such Option, by the number of Shares as to which the Option is
exercised.

                (v) The Option may, but need not, include a provision whereby
the Optionholder may elect to exercise the Option at any time while the Option
remains outstanding as to any part or all of the Shares subject to the Option,
subject to a repurchase right in favor of the Company on such terms as the Board
shall establish, which may include the use of an escrow account to hold Shares
remaining subject to the Company's repurchase right.

                                       6

            (d) TERMINATION OF CONTINUOUS SERVICE AS AN EMPLOYEE, DIRECTOR OR
CONSULTANT. If an Optionholder ceases his or her Continuous Service as an
Employee, Director or Consultant for any reason other than death or Disability,
the Optionholder may, but only within three (3) months (or such longer or
shorter period, which in no event shall be less than thirty (30) days, specified
in the Option Agreement) after the end of the Optionholder's Continuous Service
as an Employee, Director or Consultant, exercise the Option to the extent that
the Optionholder was entitled to exercise it at the date of such termination. To
the extent that the Optionholder was not entitled to exercise the Option at the
date of such termination, or if the Optionholder does not exercise such Option
within the time specified herein, the Option shall terminate.

            (e) DEATH OF OPTIONHOLDER. In the event of the death of an
Optionholder during the term of a Option granted to such Optionholder and who
remained at the time of his or her death in Continuous Service as an Employee,
Director or Consultant since the date of grant of the Option, the Option may be
exercised at any time within twelve (12) months (or such longer or shorter
period, which in no event shall be less than six (6) months, specified in the
Option Agreement) following the date of death, by the Optionholder's estate or
by a person who acquired the right to exercise the Option by bequest,
inheritance, beneficiary designation or otherwise, to the extent that the
Optionholder was entitled to exercise it on the date of death. To the extent
that the Optionholder was not entitled to exercise the Option on the date of
death that portion of the Option shall terminate on the Optionholder's date of
death. To the extent that the Optionholder was entitled to exercise the Option
on the date of death, if the Option is not exercised within the time specified
herein, the Option shall terminate.

            (f) DISABILITY OF OPTIONHOLDER. In the event of the termination of
an Optionholder's Continuous Service as an Employee, Director or Consultant on
account of Disability of the Optionholder during the term of an Option granted
to such Optionholder and who remained at the time of his or her termination on
account of Disability in Continuous Service as an Employee, Director or
Consultant since the date of grant of the Option, the Optionholder may, but only
within twelve (12) months (or such longer or shorter period, which in no event
shall be less than six (6) months, specified in the Option Agreement) after the
date the Optionholder ceases Continuous Service as an Employee, Director or
Consultant on account of such Disability, exercise the Option to the extent that
the Optionholder was entitled to exercise it at the date of such termination. To
the extent that the Optionholder was not entitled to exercise the Option at the
date of such termination, that portion of the Option shall terminate on the
Optionholder's date of Disability. To the extent that the Optionholder was
entitled to exercise the Option on the date of Disability if the Optionholder
does not exercise such Option (which the Optionholder was entitled to exercise)
within the time specified herein, the Option shall terminate.

            (g) WITHHOLDING. To the extent provided by the terms of the Option
Agreement, the Optionholder may satisfy any federal, state or local tax
withholding obligation relating to the exercise of such Option by any of the
following means or by a combination of such means or by a combination of such
means: (i) tendering a cash payment; (ii) authorizing the Company to withhold
Shares from the Shares otherwise issuable to the Optionholder as a result of the
exercise of the Option; or (iii) delivering to the Company owned and
unencumbered

                                       7
<PAGE>   8

Shares of the Common Stock of the Company. Notwithstanding the foregoing,
nothing in this subsection 7(g) shall abridge the Company's right to withhold
from any remuneration paid to the Optionholder by the Company.

            (h) TRANSFERABILITY OF OPTIONS. Except as otherwise expressly
provided in the terms of the Option Agreement, the Option may not be sold,
pledged, assigned, hypothecated, transferred, or disposed of in any manner other
than by will or by the laws of descent or distribution and may be exercised,
during the lifetime of the Optionholder, only by the Optionholder.
Notwithstanding the foregoing, the Optionholder may, by delivering written
notice to the Company, in a form satisfactory to the Company, designate a third
party who, in the event of the death of the Optionholder, shall thereafter be
entitled to exercise the Option.

         8. PROVISIONS OF STOCK AWARDS OTHER THAN OPTIONS.

            (a) STOCK BONUS AWARDS. Each stock bonus agreement shall be in such
form and shall contain such terms and conditions as the Board shall deem
appropriate. The terms and conditions of stock bonus agreements may change from
time to time, and the terms and conditions of separate stock bonus agreements
need not be identical, but each stock bonus agreement shall include (through
incorporation of provisions hereof by reference in the agreement or otherwise)
the substance of each of the following provisions:

            (i) CONSIDERATION. A stock bonus may be awarded in consideration for
past services actually rendered to the Company or an Affiliate for its benefit.

            (ii) VESTING. Shares of Common Stock awarded under the stock bonus
agreement may, but need not, be subject to a share repurchase option in favor of
the Company in accordance with a vesting schedule to be determined by the Board.

            (iii) TERMINATION OF PARTICIPANT'S CONTINUOUS SERVICE. In the event
a Participant's Continuous Service terminates, the Company may reacquire any or
all of the shares of Common Stock held by the Participant which have not vested
as of the date of termination under the terms of the stock bonus agreement.

            (iv) TRANSFERABILITY. Rights to acquire shares of Common Stock under
the stock bonus agreement shall be transferable by the Participant only upon
such terms and conditions as are set forth in the stock bonus agreement, as the
Board shall determine in its discretion, so long as Common Stock awarded under
the stock bonus agreement remains subject to the terms of the stock bonus
agreement.

            (b) RESTRICTED STOCK AWARDS. Each restricted stock purchase
agreement shall be in such form and shall contain such terms and conditions as
the Board shall deem appropriate. The terms and conditions of the restricted
stock purchase agreements may change from time to time, and the terms and
conditions of separate restricted stock purchase agreements need not be
identical, but each restricted stock purchase agreement shall include (through
incorporation of provisions hereof by reference in the agreement or otherwise)
the substance of each of the following provisions:

                                       8
<PAGE>   9

            (i) PURCHASE PRICE. The purchase price of restricted stock awards
shall not be less than eighty-five percent (85%) of the Common Stock's Fair
Market Value on the date such award is made or at the time the purchase is
consummated.

            (ii) CONSIDERATION. The purchase price of Common Stock acquired
pursuant to the restricted stock purchase agreement shall be paid either: (i) in
cash at the time of purchase; (ii) at the discretion of the Board, according to
a deferred payment or other similar arrangement with the Participant; or (iii)
in any other form of legal consideration that may be acceptable to the Board in
its discretion; provided, however, that at any time that the Company is
incorporated in Delaware, then payment of the Common Stock's "par value," as
defined in the Delaware General Corporation Law, shall not be made by deferred
payment.

            (iii) VESTING. Shares of Common Stock acquired under the restricted
stock purchase agreement may, but need not, be subject to a share repurchase
option in favor of the Company in accordance with a vesting schedule to be
determined by the Board.

            (iv) TERMINATION OF PARTICIPANT'S CONTINUOUS SERVICE. In the event a
Participant's Continuous Service terminates, the Company may repurchase or
otherwise reacquire any or all of the shares of Common Stock held by the
Participant which have not vested as of the date of termination under the terms
of the restricted stock purchase agreement.

            (v) TRANSFERABILITY. Rights to acquire shares of Common Stock under
the restricted stock purchase agreement shall be transferable by the Participant
only upon such terms and conditions as are set forth in the restricted stock
purchase agreement, as the Board shall determine in its discretion, so long as
Common Stock awarded under the restricted stock purchase agreement remains
subject to the terms of the restricted stock purchase agreement.

            (c) WITHHOLDING OBLIGATIONS. To the extent provided by the terms of
a Stock Award Agreement, the Participant may satisfy any federal, state or local
tax withholding obligation relating to the exercise or acquisition of Common
Stock under a Stock Award by any of the following means (in addition to the
Company's right to withhold from any compensation paid to the Participant by the
Company) or by a combination of such means: (i) tendering a cash payment; (ii)
authorizing the Company to withhold shares of Common Stock from the shares of
Common Stock otherwise issuable to the Participant as a result of the exercise
or acquisition of Common Stock under the Stock Award, provided, however, that no
shares of Common Stock are withheld with a value exceeding the minimum amount of
tax required to be withheld by law; or (iii) delivering to the Company owned and
unencumbered shares of Common Stock.

         9. ADJUSTMENTS UPON CHANGES IN CAPITALIZATION OR MERGER.

            (a) CAPITALIZATION ADJUSTMENTS. If any change is made in the Common
Stock subject to the Plan, or subject to any Stock Award, without the receipt of
consideration by the Company (through merger, consolidation, reorganization,
recapitalization, reincorporation, stock dividend, dividend in property other
than cash, stock split, liquidating dividend, combination of shares, exchange of
shares, change in corporate structure or other transaction not involving the
receipt of consideration by the Company), the Plan will be appropriately
adjusted in the class(es) and maximum number of securities subject to the Plan
pursuant to Section 3, and

                                       9
<PAGE>   10

the outstanding Stock Awards will be appropriately adjusted in the class(es) and
number of securities and price per Share subject to such outstanding Stock
Awards. The Board shall make such adjustments, and its determination shall be
final, binding and conclusive. (The conversion of any convertible securities of
the Company shall not be treated as a transaction "without receipt of
consideration" by the Company.)

            (b) CHANGE IN CONTROL--DISSOLUTION OR LIQUIDATION. In the event of a
dissolution or liquidation of the Company, then all outstanding Stock Awards
shall terminate immediately prior to such event.

            (c) CHANGE IN CONTROL--ASSET SALE, MERGER, CONSOLIDATION OR REVERSE
MERGER. In the event of (i) a sale, lease or other disposition of all or
substantially all of the assets of the Company, (ii) a merger or consolidation
in which the Company is not the surviving corporation, or (iii) a reverse merger
in which the Company is the surviving corporation but the shares of Common Stock
outstanding immediately preceding the merger are converted by virtue of the
merger into other property, whether in the form of securities, cash or
otherwise, then any surviving corporation or acquiring corporation shall assume
any Stock Awards outstanding under the Plan or shall substitute similar stock
awards (including an award to acquire the same consideration paid to the
stockholders in the transaction described in this subsection 9(c)) for those
outstanding under the Plan. In the event any surviving corporation or acquiring
corporation refuses to assume such Stock Awards or to substitute similar stock
awards for those outstanding under the Plan, then with respect to Stock Awards
held by Participants whose Continuous Service has not terminated, the vesting of
such Stock Awards (and, if applicable, the time during which such Stock Awards
may be exercised) shall be accelerated in full, and the Stock Awards shall
terminate if not exercised (if applicable) at or prior to such event. With
respect to any other Stock Awards outstanding under the Plan, such Stock Awards
shall terminate if not exercised (if applicable) prior to such event.

         10. CONDITIONS UPON ISSUANCE OF SHARES.

             The Company may require the Participant (or any person to whom a
Stock Award is transferred) to execute such documents and to provide such
representations, written assurances or information which the Company shall
determine is necessary, desirable or appropriate to comply with applicable
securities and other laws as a condition of granting a Stock Award to such
Participant or permitting the Participant (or any person to whom a Stock Award
is transferred) to exercise such Stock Award. The Company may, upon advice of
counsel to the Company, place legends on stock certificates issued under the
Plan as such counsel deems necessary or appropriate in order to comply with
applicable securities and other laws, including, but not limited to, legends
restricting the transfer of the shares.

         11. RESERVATION OF SHARES.

             (a) The Company, during the term of this Plan, will at all times
reserve and keep available such number of Shares as shall be sufficient to
satisfy the requirements of the Plan.

             (b) Inability of the Company to obtain authority from any
regulatory body having jurisdiction, which authority is deemed by the Company's
counsel to be necessary to the

                                       10
<PAGE>   11

lawful issuance and sale of any Shares hereunder, shall relieve the Company of
any liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

         12. AMENDMENT, SUSPENSION AND TERMINATION OF THE PLAN AND STOCK AWARDS.

             (a) AMENDMENT, SUSPENSION AND TERMINATION. The Board may amend,
suspend or terminate the Plan from time to time in such respects as the Board
may deem advisable in the Board's sole discretion. Notwithstanding the
foregoing, the Plan terminates when all reserved Shares have been issued and
cannot return to the reserve.

             (b) EFFECT OF AMENDMENT, SUSPENSION OR TERMINATION. Any amendment,
suspension or termination of the Plan shall not adversely affect Stock Awards
already granted, as determined by the Board in good faith, and such Stock Awards
shall remain in full force and effect as if the Plan had not been amended,
suspended or terminated unless mutually agreed otherwise between the Participant
and the Board, which agreement must be in writing and signed by the Participant
and the Company. Notwithstanding the foregoing, any amendment which increases
the benefits provided or to be provided under the Plan shall not require the
consent of the Participants.

             (c) AMENDMENT OF STOCK AWARDS. The Board at any time, and from time
to time, may amend the terms of some or all Stock Awards; provided, however,
that if the Board makes a good faith determination that the effect of such an
amendment, taken as a whole, would be to impair the Participant's rights and/or
increase the Participant's obligations under the Stock Award, then such
amendment shall not be effective as to a particular Stock Award unless the
Company requests the consent of the Participant and such Participant consents in
writing.

         13. USE OF PROCEEDS FROM STOCK.

             Proceeds from the sale of Common Stock pursuant to Stock Awards
shall constitute general funds of the Company.

         14. EFFECTIVE DATE.

             The Plan shall become on the date the Plan is adopted by the Board.

         15. CHOICE OF LAW.

             The law of the State of Colorado shall govern all questions
concerning the construction, validity and interpretation of this Plan, without
regard to such state's conflict of laws rules.
