                         1997 Amended Stock Option Plan


     1.   Purposes of the Plan. The purposes of this Stock Option Plan are to
attract and retain the best available personnel for positions of substantial
responsibility, to provide additional incentive to Employees and Consultants of
the Company and any Parent or Subsidiary, to compensate Non-Employee Directors
of the Company and to promote the success of the Company's business. Options
granted under the Plan may be Incentive Stock Options or Nonstatutory Stock
Options, as determined by the Administrator at the time of grant of an option
and subject to the applicable provisions of Section 422 of the Code and the
regulations promulgated thereunder.

     2.   Definitions. As used herein, the following definitions shall apply:

          (a)  "Administrator" means the Board or the Compensation Committee
appointed by the Board.

          (b)  "Board" means the Board of Directors of the Company.

          (c)  "Code" means the Internal Revenue Code of 1986, as amended.

is not interrupted or terminated. Continuous Status as an Employee or Consultant
shall not be considered interrupted in the case of (i) any leave of absence
approved by the Company or (ii) transfers between locations of the Company or
between the Company, its Parent, any Subsidiary, or any successor. A leave of
absence approved by the Company shall include sick leave, military leave, or any
other personal leave. For purposes of Incentive Stock Options, no such leave may
exceed 90 days, unless reemployment upon expiration of such leave is guaranteed
by statute or contract, including Company policies. If reemployment upon
expiration of a leave of absence approved by the Company is not so guaranteed,
on the 181st day of such leave any Incentive Stock Option held by the Optionee
shall cease to be treated as an Incentive Stock Option and shall be treated for
tax purposes as a Nonstatutory Stock Option.

Fair Market Value shall be the closing sales price for such stock (or the
closing bid, if no sales were reported) as quoted on such exchange or system for
the last market trading day prior to the time of determination, as reported in
The Wall Street Journal or such other source as the Administrator deems
reliable;

          (t)  "Permitted Transferee" means a member of a holder's immediate

the Plan, the maximum aggregate number of Shares which may be optioned and sold
under the Plan is 1,500,000 Shares, increased, as of May 1 of each fiscal year
commencing May 1, 2000, by an amount that, when aggregated with the number of
shares reserved for issuance as stock options under all stock option plans
sponsored by the Company, equals fifteen percent (15%) of the number of Shares
outstanding as of the close of business on the last business day of April each
year. The maximum number of Shares with respect to which Options may be awarded
under the Plan during any fiscal year to any Employee shall be 500,000. The
Shares may be authorized, but unissued, or reacquired Common Stock.

          If an Option expires or becomes unexercisable without having been
exercised in full, or is surrendered pursuant to an option exchange program
authorized by the Administrator, the unpurchased Shares which were subject
thereto shall become available for future grant or sale under the Plan (unless
the Plan has terminated); provided, however, that Shares that have actually been
issued under the Plan shall not be returned to the Plan and shall not become
available for future distribution under the Plan, except that if unvested Shares
are repurchased by the Company at their original purchase price, such Shares
shall become available for future grant under the Plan.

     4.   Administration of the Plan.

          (a)  Plan Procedure. With respect to Option grants awarded to
Employees, Consultants or Non-Employee Directors, the Plan shall be administered
by (A) the Board or (B) the Compensation Committee designated by the Board,
which committee shall be constituted to satisfy the legal requirements, if any,
relating to the administration of incentive stock option plans of state
corporate and securities laws, of the Code, and of any stock exchange or
national market system upon which the Common Stock is then listed or traded (the
"Applicable Laws"). Once appointed, such Committee shall serve in its designated
capacity until otherwise directed by the Board. The Board may increase the size
of the Committee and appoint additional members, remove members (with or without
cause) and substitute new members, fill vacancies (however caused), and remove
all members of the Committee and thereafter directly administer the Plan, all to
the extent permitted by Applicable Laws.

          (b)  Powers of the Administrator. Subject to the provisions of the
Plan and approval of any relevant authorities, including the approval, if
required, of any stock exchange or national market system upon which the Common
Stock is then listed, the Administrator shall have the authority, in its
discretion:

               (i)  to determine the Fair Market Value of the Common Stock, in
accordance with Section 2(l) of the Plan;

               (ii) to select the Consultants and Employees to whom Options may
from time to time be granted hereunder;

               (iii) to determine whether and to what extent Options are granted
hereunder;

               (iv) to determine the number of shares of Common Stock to be
covered by each such award granted hereunder;

               (v)  to approve forms of agreement for use under the Plan;

               (vi) to determine the terms and conditions, not inconsistent with
the terms of the Plan, of any award granted hereunder. Such terms and conditions
may include, but are not limited to, the exercise price, the time or times when
Options may be exercised, any vesting acceleration or waiver of forfeiture
restrictions, and any restriction or limitation regarding any Option or the
Shares relating thereto, based in each case on such factors as the
Administrator, in its sole discretion, shall determine;

               (vii) to determine whether and under what circumstances an Option
may be settled in cash under Section 10(e) instead of Common Stock;


                                      -4-
<PAGE>   5


               (viii) to reduce the exercise price of any Option to the then
current Fair Market Value only in the event the reduction of the exercise price
(i) effects less than ten percent (10%) of the Shares authorized for grant under
the Plan, (ii) is for a legitimate corporate purpose such as retention of one or
more key persons and (iii) is for the purpose of maintaining option value due to
extreme circumstances beyond management's control;

               (ix) to provide for the early exercise of Options for the
purchase of unvested Shares, subject to such terms and conditions as the
Administrator may determine; and

               (x)  to construe and interpret the terms of the Plan and awards
granted pursuant to the Plan.

          (c)  Effect of Administrator's Decision. All decisions, determinations
and interpretations of the Administrator shall be final and binding on all
Optionees and any other holders of any Options.

     5.   Eligibility.

          (a)  Nonstatutory Stock Options may be granted to Employees,
Consultants and Non-Employee Directors. Incentive Stock Options may be granted
only to Employees. An Employee, Consultant or Non-Employee Director who has been
granted an Option may, if otherwise eligible, be granted additional Options.

          (b)  Each Option shall be designated in the written option agreement
as either an Incentive Stock Option or a Nonstatutory Stock Option. However,
notwithstanding such designation, to the extent that the aggregate Fair Market
Value of the Shares with respect to which Incentive Stock Options are
exercisable for the first time by the Optionee during any calendar year (under
all plans of the Company and any Parent or Subsidiary) exceeds $100,000, such
Options shall be treated as Nonstatutory Stock Options.

          For purposes of this Section 5(b), Incentive Stock Options shall be
taken into account in the order in which they were granted, and the Fair Market
Value of the Shares shall be determined as of the time the Option with respect
to such Shares is granted.

          (c)  The Plan shall not confer upon any Optionee any right with
respect to the continuation of the Optionee's employment or consulting
relationship with the Company, nor shall it interfere in any way with the
Optionee's right or the Company's right to terminate the Optionee's employment
or consulting relationship at any time, with or without cause.

     6.   Term of Plan. The Plan shall become effective upon the earlier to
occur of its adoption by the Board of Directors or its approval by the
stockholders of the Company, as described in Section 15 of the Plan. It shall
continue in effect for a term of ten (10) years unless sooner terminated under
Section 15 of the Plan.


                                      -5-
<PAGE>   6


     7.   Term of Option. The term of each Option shall be the term stated in
the Option Agreement; provided, however, that the term shall be no more than ten
(10) years from the date of grant thereof. However, in the case of an Incentive
Stock Option granted to an Optionee who, at the time the Option is granted, owns
stock representing more than ten percent (10%) of the voting power of all
classes of stock of the Company or any Parent or Subsidiary, the term of the
Option shall be five (5) years from the date of grant thereof or such shorter
term as may be provided in the Option Agreement.

     8.   Option Exercise Price and Consideration.

         (a)  The per share exercise price for the Shares to be issued pursuant
to exercise of an Option shall be such price as is determined by the
Administrator, but shall be subject to the following:

               (i)  In the case of an Incentive Stock Option

                    (A)  granted to an Employee who, at the time of the grant of
such Incentive Stock Option, owns stock representing more than ten percent (10%)
of the voting power of all classes of stock of the Company or any Parent or
Subsidiary, the per Share exercise price shall be no less than 110% of the Fair
Market Value per Share on the date of grant.

                    (B)  granted to any Employee other than an Employee
described in the preceding paragraph, the per Share exercise price shall be no
less than 100% of the Fair Market Value per Share on the date of grant.

                    (ii) In the case of a Nonstatutory Stock Option, the per
share exercise price shall be determined by the Administrator but shall not be
less than one hundred percent (100%) of the Fair Market Value per Share on the
date of grant; provided, however, that a per share exercise price of no less
than eighty-five percent (85%) of the Fair Market Value per Share on the date of
grant shall be permitted for a Nonstatutory Stock Option expressly awarded to an
Employee in lieu of a reasonable amount of salary or cash bonus.

          (b)  The consideration to be paid for the Shares to be issued upon
exercise of an Option, including the method of payment, shall be determined by
the Administrator (and, in the case of an Incentive Stock Option, shall be
determined at the time of grant) and may consist entirely of (1) cash, (2)
check, (3) promissory note, (4) other Shares which (x) in the case of Shares
acquired upon exercise of an Option have been owned by the Optionee for more
than six months on the date of surrender and (y) have a Fair Market Value on the
date of surrender equal to the aggregate exercise price of the Shares as to
which such Option shall be exercised, (5) delivery of a properly executed
exercise notice together with such other documentation as the Administrator and
the broker, if applicable, shall require to effect an exercise of the Option and
delivery to the Company of the sale or loan proceeds required to pay the
exercise price, or (6) any combination of the foregoing methods


                                      -6-
<PAGE>   7


of payment. In making its determination as to the type of consideration to
accept, the Administrator shall consider if acceptance of such consideration may
be reasonably expected to benefit the Company.

     9.   Grants to Non-Employee Directors. The Administrator may, from time to
time, in its discretion, award Nonstatutory Stock Options to Non-Employee
Directors, for the number of shares of Common Stock, and upon such terms and
conditions as may be consistent with the Plan, based in each case on such
factors as the Administrator, in its sole discretion, shall determine.

     10.  Exercise of Option.

          (a)  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 Administrator, including performance criteria with respect
to the Company and/or the Optionee, and as shall be permissible under the terms
of the Plan.

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

               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 Administrator, consist of any
consideration and method of payment allowable under Section 8(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 Optioned Stock,
notwithstanding the exercise of the Option. The Company shall issue (or cause to
be issued) such stock certificate promptly upon exercise of the Option. No
adjustment will be made 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 13 of the Plan.

               Exercise of an Option in any manner shall result in a decrease in
the number of Shares which thereafter may be available, both for purposes of the
Plan and for sale under the Option, by the number of Shares as to which the
Option is exercised.

          (b)  Termination of Employment or Consulting Relationship. Upon
termination of an Optionee's Continuous Status as an Employee or Consultant,
other than upon the Optionee's death or Disability, the Optionee may exercise
his or her Option, but only within such period of time as is specified in the
Notice of Grant, and only to the extent that the Optionee was entitled to
exercise it at the date of termination (but in no event later than the
expiration of the term of such Option as set forth in the Notice of Grant). In
the absence of a specified time in the Notice of Grant, the Option


                                      -7-
<PAGE>   8
shall remain exercisable for three (3) months following the Optionee's
termination. In the case of an Incentive Stock Option, such period of time for
exercise shall not exceed three (3) months from the date of termination. If, on
the date of termination, the Optionee is not entitled to exercise the Optionee's
entire Option, the Shares covered by the unexercisable portion of the Option
shall revert to the Plan. If, after termination, the Optionee does not exercise
his or her Option within the time specified by the Administrator, the Option
shall terminate, and the Shares covered by such Option shall revert to the Plan.

          Notwithstanding the above, in the event of an Optionee's change in
status from Consultant to Employee or Employee to Consultant, an Optionee's
Continuous Status as an Employee or Consultant shall not automatically terminate
solely as a result of such change in status. However, in such event, an
Incentive Stock Option held by the Optionee shall cease to be treated as an
Incentive Stock Option and shall be treated for tax purposes as a Nonstatutory
Stock Option three months and one day following such change of status.

     The provisions of this Section 10(b) shall not be applicable to
Non-Employee Directors.

          (c)  Disability of Optionee. In the event of termination of an
Optionee's Continuous Status as an Employee or Consultant as a result of his or
her Disability, the Optionee may, but only within twelve (12) months from the
date of such termination (and in no event later than the expiration date of the
term of his or her Option as set forth in the Option Agreement), exercise the
Option to the extent the Optionee was otherwise entitled to exercise it on the
date of such termination. To the extent that the Optionee is not entitled to
exercise the Option on the date of termination, or if the Optionee does not
exercise the Option to the extent so entitled within the time specified herein,
the Option shall terminate, and the Shares covered by the Option shall revert to
the Plan.

          (d)  Death of Optionee. In the event of the death of an Optionee, the
Option may be exercised at any time within twelve (12) months following the date
of death (but in no event later than the expiration of the term of such Option
as set forth in the Notice of Grant), by the Optionee's estate or by a person
who has acquired the right to exercise the Option by bequest or inheritance, but
only to the extent that the Optionee was entitled to exercise the Option at the
date of death. If, at the time of death, the Optionee was not entitled to
exercise his or her entire Option, the Shares covered by the unexercisable
portion of the Option shall immediately revert to the Plan. If, after death, the
Optionee's estate or a person who acquires the right to exercise the Option by
bequest or inheritance does not exercise the Option within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

          (e)  Buyout Provisions. The Administrator may at any time offer to buy
out for a payment in cash or Shares, an Option previously granted, based on such
terms and conditions as the Administrator shall establish and communicate to the
Optionee at the time that such offer is made.


                                      -8-
<PAGE>   9

          (f)  Rule 16b-3. Options granted to persons subject to Section 16(b)
of the Exchange Act must comply with Rule 16b-3 and shall contain such
additional conditions or restrictions as may be required thereunder to qualify
for the maximum exemption from Section 16 of the Exchange Act with respect to
Plan transactions.

     11.  Stock Withholding to Satisfy Withholding Tax Obligations. At the
discretion of the Administrator, Optionees may satisfy withholding obligations
as provided in this Section 11. When an Optionee incurs tax liability in
connection with an Option which tax liability is subject to tax withholding
under applicable tax laws, and the Optionee is obligated to pay the Company an
amount required to be withheld under applicable tax laws, the Optionee may
satisfy the withholding tax obligation by electing to have the Company withhold
from the Shares to be issued upon exercise of the Option that number of Shares
having a Fair Market Value equal to the amount required to be withheld. The Fair
Market Value of the Shares to be withheld shall be determined on the date that
the amount of tax to be withheld is to be determined (the "Tax Date").

     All elections by an Optionee to have Shares withheld for this purpose shall
be made in writing in a form acceptable to the Administrator and shall be
subject to the following restrictions:

          (a)  the election must be made on or prior to the applicable Tax Date;

          (b)  once made, the election shall be irrevocable as to the particular
Shares of the Option as to which the election is made;

          (c)  all elections shall be subject to the consent or disapproval of
the Administrator.

     In the event the election to have Shares withheld is made by an Optionee
and the Tax Date is deferred under Section 83 of the Code because no election is
filed under Section 83(b) of the Code, the Optionee shall receive the full
number of Shares with respect to which the Option is exercised but such Optionee
shall be unconditionally obligated to tender back to the Company the proper
number of Shares on the Tax Date.

     12.  Transferability of Options and Rights. Incentive Stock Options granted
under the Plan shall not be transferable otherwise than by will or the laws of
descent and distribution, or pursuant to a qualified domestic relations order as
defined by the Code or Title I of the Employee Retirement Income Security Act of
1974, as amended, or the rules thereunder. Incentive Stock Options shall be
exercisable during the lifetime of the Employee only by the Employee or by the
Employee's guardian or legal representative (unless such exercise would
disqualify it as an Incentive Stock Option). Unless the Administrator otherwise
provides in an agreement regarding the award of non-qualified stock options or
rights (not granted in connection with an Incentive Stock Option), non-qualified
stock options or rights (not granted in connection with Incentive Stock Options)
may be transferred by the holder to Permitted Transferees, provided that there
cannot be any consideration for the transfer.

     13.  Adjustments Upon Changes in Capitalization or Merger.


                                      -9-
<PAGE>   10


          (a)  Changes in Capitalization. Subject to any required action by the
stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an Option.

          (b)  Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated. To the extent it has not been previously exercised, an
Option will terminate immediately prior to the consummation of such proposed
action.

          (c)  Acquisition Events

               (1)  Consequences of Acquisition Events. Upon the occurrence of
an Acquisition Event (as defined below), or the execution by the Company of any
agreement with respect to an Acquisition Event, the Board shall take any one or
more of the following actions with respect to then outstanding Options: (i)
provide that outstanding Options shall be assumed or equivalent Options shall be
substituted by the acquiring or succeeding entity (or an affiliate thereof),
provided that any such Options substituted for Incentive Stock Options shall
satisfy, in the determination of the Board, the requirements of Section 422(a)
of the Code; (ii) upon written notice to the Optionees, provide that all then
unexercised Options will become exercisable in full as of a specified date (the
"Acceleration Date") prior to the Acquisition Event and will terminate
immediately prior to the consummation of such Acquisition Event, except to the
extent exercised by the Optionees between the Acceleration Date and the
consummation of the Acquisition Event or (iii) in the event of an Acquisition
Event under the terms of which holders of Common Stock will receive upon
consummation thereof a cash payment for each share of Common Stock surrendered
pursuant to such


                                      -10-
<PAGE>   11


Acquisition Event (the "Acquisition Price") provide that all outstanding Options
shall terminate upon consummation of such Acquisition Event and each Optionee
shall receive, in exchange therefor, a cash payment equal to the amount (if any)
by which (A) the Acquisition Price multiplied by the number of shares of Common
Stock subject to such outstanding Options (whether or not then exercisable),
exceeds (B) the aggregate exercise price of such Options.

     An "Acquisition Event" shall mean: (a) any merger or consolidation which
results in the voting securities of the Company outstanding immediately prior
thereto continuing to represent (either by remaining outstanding or by being
converted into voting securities of the surviving or acquiring entity) less than
60% of the combined voting power of the voting securities of the Company or such
surviving or acquiring entity outstanding immediately after such merger or
consolidation; (b) any sale of all or substantially all of the assets of the
Company; (c) the complete liquidation of the Company; or (d) the acquisition of
"beneficial ownership" (as defined in Rule 13d-3 under the Exchange Act) of
securities of the Company representing 50% or more of the combined voting power
of the Company's then outstanding securities (other than through a merger or
consolidation or an acquisition of securities directly from the Company) by any
"person", as such term is used in Sections 13 (d) and 14 (d) of the Exchange Act
other than the Company, any trustee or other fiduciary holding securities under
an employee benefit plan of the Company, or any entity owned directly or
indirectly by the stockholders of the Company in substantially the same
proportion as their ownership of stock of the Company.

          (2)  Assumption of Options Upon Certain Events. The Board may grant
options under the Plan in substitution for stock and stock-based awards held by
employees of another entity who become Employees as a result of a merger or
consolidation of the employing entity with the Company or the acquisition by the
Company of property or stock of the employing entity. The substitute options
shall be granted on such terms and conditions as the Board considers appropriate
in the circumstances.

     14.  Time of Granting Options. The date of grant of an Option shall, for
all purposes, be the date on which the Administrator makes the determination
granting such Option, or such other date as is determined by the Administrator.
Notice of the determination shall be given to each Employee or Consultant to
whom an Option is so granted within a reasonable time after the date of such
grant.

     15.  Amendment and Termination of the Plan.

          (a)  Amendment and Termination. The Board may at any time amend,
alter, suspend or discontinue the Plan, but no amendment, alteration, suspension
or discontinuation shall be made which would impair the rights of any Optionee
under any grant theretofore made, without his or her consent. In addition, to
the extent necessary and desirable to comply with Rule 16b-3 under the Exchange
Act or with Section 422 of the Code (or any other applicable law or regulation,
including the requirements of any stock exchange or national market system upon
which the Common Stock is then listed), the Company shall obtain stockholder
approval of any Plan amendment in such a manner and to such a degree as
required.

<PAGE>   12


          (b)  Effect of Amendment or Termination. Any such amendment or
termination of the Plan shall not affect Options already granted, and such
Options shall remain in full force and effect as if this Plan had not been
amended or terminated, unless mutually agreed otherwise between the Optionee and
the Board, which agreement must be in writing and signed by the Optionee and the
Company.

     16.  Conditions Upon Issuance of Shares. Shares shall not be issued
pursuant to the exercise of an Option unless the exercise of such Option and the
issuance and delivery of such Shares pursuant thereto shall comply with all
relevant provisions of law, including, without limitation, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange or national market system
upon which the Common Stock is then listed or traded, and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

          As a condition to the exercise of an Option, the Company may require
the person exercising such Option to represent and warrant at the time of any
such exercise that the Shares are being purchased only for investment and
without any present intention to sell or distribute such Shares if, in the
opinion of counsel for the Company, such a representation is required by any of
the aforementioned relevant provisions of law.

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

          The 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 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.

     18.  Agreements. Options shall be evidenced by written agreements in such
form as the Administrator shall approve from time to time.

     19.  Stockholder Approval. Continuance of the Plan shall be subject to
approval by the stockholders of the Company within twelve (12) months before or
after the date the Plan is adopted. Such stockholder approval shall be obtained
in the degree and manner required under applicable state and federal law and the
rules of any stock exchange or national market system upon which the Common
Stock is then listed or traded.

                         1997 AMENDED STOCK OPTION PLAN
                                OPTION AGREEMENT

     1.   Grant of Option. Pegasus Systems, Inc. (the "Company"), hereby grants
to the Optionee (the "Optionee") named in the Notice of Grant, an option (the
"Option") to purchase the total number of shares of Common Stock (the "Shares")
set forth in the Notice of Grant, at the exercise price per share set forth in
the Notice of Grant (the "Exercise Price") subject to the terms, definitions and
provisions of the 1997 Amended Stock Option Plan (the "Plan") adopted by the
Company, which is incorporated herein by reference. Unless otherwise defined
herein, the terms defined in the Plan shall have the same defined meanings in
this Option Agreement.

          If designated in the Notice of Grant as an Incentive Stock Option
("ISO"), this Option is intended to qualify as an Incentive Stock Option as
defined in Section 422 of the Code. However, if this Option is intended to be an
Incentive Stock Option, to the extent that it exceeds the $100,000 rule of Code
Section 422(d) it shall be treated as a Nonstatutory Stock Option ("NSO").

     2.   Exercise of Option. This Option shall be exercisable during its term
in accordance with the Vesting Schedule set out in the Notice of Grant and with
the provisions of Section 9 of the Plan as follows:

          (i)  Right to Exercise.

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

               (b)  In the event of Optionee's death, disability or other
termination of the Optionee's Continuous Status as an Employee or Consultant,
the exercisability of the Option is governed by Sections 6, 7 and 8 below,
subject to the limitation contained in subsection 2(i)(c).

               (c)  In no event may this Option be exercised after the date of
expiration of the term of this Option as set forth in the Notice of Grant.

          (ii) Method of Exercise. This Option shall be exercisable by written
notice (in the form attached as Exhibit A) which shall state the election to
exercise the Option, the number of Shares in respect of which the Option is
being exercised, and such other representations and agreements as to the
holder's investment intent with respect to such shares of Common Stock as may be
required by the Company pursuant to the provisions of the Plan. Such written
notice shall be signed by the Optionee and shall be delivered in person or by
certified mail to the Secretary of the Company. The written notice shall be
accompanied by payment of the Exercise Price. This Option shall be deemed to be
exercised upon receipt by the Company of such written notice accompanied by the
Exercise Price.


                                       1
<PAGE>   15


          No Shares will be issued pursuant to the exercise of an Option unless
such issuance and such exercise shall comply with all relevant provisions of law
and the requirements of any stock exchange or national market system upon which
the Common Stock is then listed. Assuming such compliance, for income tax
purposes the Shares shall be considered transferred to the Optionee on the date
on which the Option is exercised with respect to such Shares.

     3.   Optionee's Representations. In the event the Shares purchasable
pursuant to the exercise of this Option have not been registered under the
Securities Act of 1933, as amended, at the time this Option is exercised,
Optionee shall, if required by the Company, concurrently with the exercise of
all or any portion of this Option, deliver to the Company his or her Investment
Representation Statement in the form attached hereto as Exhibit B.

     4.   Lock-Up Period. Optionee hereby agrees that if so requested by the
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
longer period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act. The Company may impose stop-transfer instructions with respect
to securities subject to the foregoing restrictions until the end of such Market
Standoff Period.

     5.   Method of Payment. Payment of the Exercise Price shall be by any of
the following, or a combination thereof, at the election of the Optionee:

          (i)  cash; or

          (ii) check; or

          (iii) surrender of other shares of Common Stock of the Company which
(A) in the case of Shares acquired pursuant to the exercise of a Company option,
have been owned by the Optionee for more than six (6) months on the date of
surrender, and (B) have a Fair Market Value on the date of surrender equal to
the Exercise Price of the Shares as to which the Option is being exercised; or

          (iv) to the extent authorized by the Company, delivery of a properly
executed exercise notice together with such other documentation as the
Administrator and the broker, if applicable, shall require to effect an exercise
of the Option and delivery to the Company of the sale or loan proceeds required
to pay the Exercise Price.

     6.   Restrictions on Exercise. This Option may not be exercised if the
issuance of such Shares upon such exercise or the method of payment of
consideration for such shares would constitute a violation of any applicable
federal or state securities or other law or regulation, including any rule under
Part 207 of Title 12 of the Code of Federal Regulations as promulgated by the
Federal


                                       2

Reserve Board. As a condition to the exercise of this Option, the Company may
require Optionee to make any representation and warranty to the Company as may
be required by any applicable law or regulation.

     7.   Termination of Relationship. In the event an Optionee's Continuous
Status as an Employee or Consultant terminates, Optionee may, to the extent
otherwise so entitled at the date of such termination (the "Termination Date"),
exercise this Option during the Termination Period set out in the Notice of
Grant. To the extent that Optionee was not entitled to exercise this Option at
the date of such termination, or if Optionee does not exercise this Option
within the time specified herein, the Option shall terminate.

     8.   Disability of Optionee. Notwithstanding the provisions of Section 6
above, in the event of termination of an Optionee's Continuous Status as an
Employee or Consultant as a result of his or her Disability, Optionee may, but
only within twelve (12) months from the date of such termination (and in no
event later than the expiration date of the term of such Option as set forth in
the Notice of Grant) exercise the Option to the extent otherwise entitled to
exercise it at the date of such termination. To the extent that Optionee is not
entitled to exercise the Option at the date of termination, or if Optionee does
not exercise such Option to the extent so entitled within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

     9.   Death of Optionee. In the event of termination of Optionee's
Continuous Status as an Employee or Consultant as a result of the death of
Optionee, the Option may be exercised at any time within twelve (12) months
following the date of death (but in no event later than the date of expiration
of the term of this Option as set forth in Section 10 below), by Optionee's
estate or by a person who acquired the right to exercise the Option by bequest
or inheritance, but only to the extent the Optionee could exercise the Option at
the date of death.

     10.  Non-Transferability of Option. Except as otherwise permitted by
Section 12 of the Plan, this Option may not be transferred in any manner
otherwise than by will or by the laws of descent or distribution and may be
exercised during the lifetime of Optionee only by Optionee. The terms of this
Option shall be binding upon the executors, administrators, heirs, successors
and assigns of the Optionee.

     11.  Term of Option. This Option may be exercised only within the term set
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option. Provided, however, that
if this Option is designated as an Incentive Stock Option and the Optionee is a
more than ten percent (10%) stockholder, the limitations set out in Section 7 of
the Plan regarding Options designated as Incentive Stock Options and Options
granted to more than ten percent (10%) stockholders shall apply to this Option.

     12.  Tax Consequences. Set forth below is a brief summary as of the date of
this Option of some of the federal tax consequences of exercise of this Option
and disposition of the Shares.


                                       3
<PAGE>   17


THIS SUMMARY IS NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE
SUBJECT TO CHANGE. OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS
OPTION OR DISPOSING OF THE SHARES.

          (i)  Exercise of an ISO. If this Option qualifies as an ISO, there
will be no regular federal income tax liability upon the exercise of the Option,
although the excess, if any, of the Fair Market Value of the Shares on the date
of exercise over the Exercise Price will be treated as an adjustment to the
alternative minimum tax for federal tax purposes and may subject the Optionee to
the alternative minimum tax in the year of exercise.

          (ii) Exercise of an NSO. Upon the exercise of an NSO, the Optionee
will be treated as having received compensation income (taxable at ordinary
income tax rates) equal to the excess, if any, of the Fair Market Value of the
Shares on the date of exercise over the Exercise Price. If Optionee is an
Employee, the Company will be required to withhold from Optionee's compensation
or collect from Optionee and pay to the applicable taxing authorities an amount
equal to a percentage of this compensation income at the time of exercise.

          (iii) Disposition of Shares. In the case of an NSO, if Shares are held
for at least one year, any gain realized on disposition of the Shares will be
treated as long-term capital gain for federal income tax purposes. In the case
of an ISO, if Shares transferred pursuant to the Option are held for at least
one year after exercise and are disposed of at least two years after the Date of
Grant, any gain realized on disposition of the Shares will also be treated as
long-term capital gain for federal income tax purposes. If Shares purchased
under an ISO are disposed of within such one-year period or within two years
after the Date of Grant, any gain realized on such disposition will be treated
as compensation income (taxable at ordinary income rates) to the extent of the
difference between the Exercise Price and the lesser of (1) the Fair Market
Value of the Shares on the date of exercise, or (2) the sale price of the
Shares.

          (iv) Notice of Disqualifying Disposition of ISO Shares. If the Option
granted to Optionee herein is an ISO, and if Optionee sells or otherwise
disposes of any of the Shares acquired pursuant to the ISO on or before the
later of (1) the date two years after the Date of Grant, or (2) the date one
year after the date of exercise, the Optionee shall immediately notify the
Company in writing of such disposition. Optionee agrees that Optionee may be
subject to income tax withholding by the Company on the compensation income
recognized by the Optionee.

     OPTIONEE ACKNOWLEDGES AND AGREES THAT THE VESTING OF SHARES PURSUANT TO THE
OPTION HEREOF IS EARNED ONLY BY CONTINUING CONSULTANCY OR EMPLOYMENT AT THE WILL
OF THE COMPANY (NOT THROUGH THE ACT OF BEING HIRED, BEING GRANTED THIS OPTION OR
ACQUIRING SHARES HEREUNDER). OPTIONEE FURTHER ACKNOWLEDGES AND AGREES THAT
NOTHING IN THIS AGREEMENT, NOR IN THE COMPANY'S 1997 AMENDED STOCK OPTION PLAN
WHICH IS INCORPORATED HEREIN BY REFERENCE, SHALL CONFER UPON OPTIONEE ANY RIGHT
WITH RESPECT TO CONTINUATION OF EMPLOYMENT OR CONSULTANCY BY THE COMPANY, NOR
SHALL IT INTERFERE IN ANY WAY WITH OPTIONEE'S RIGHT OR THE COMPANY'S RIGHT TO
TERMINATE OPTIONEE'S EMPLOYMENT OR CONSULTANCY AT ANY TIME, WITH OR WITHOUT
CAUSE.

     Optionee acknowledges receipt of a copy of the Plan and represents that he
is familiar with the terms and provisions thereof, and hereby accepts this
Option subject to all of the terms and provisions thereof. Optionee has reviewed
the Plan and this Option in their entirety, has had an opportunity to obtain the
advice of counsel prior to executing this Option and fully understands all
provisions of the Option. Optionee hereby agrees to accept as binding,
conclusive and final all decisions or interpretations of the Administrator upon
any questions arising under the Plan or this Option. Optionee further agrees to
notify the Company upon any change in the residence address indicated below.

                                 EXERCISE NOTICE


Pegasus Systems, Inc.
3811 Turtle Creek Boulevard
Suite 1100
Dallas, Texas 75219
Attention:  Secretary

     1    Exercise of Option. Effective as of today, ___________, 19__, the
undersigned ("Optionee") hereby elects to exercise Optionee's option to purchase
_________ shares of the Common Stock (the "Shares") of Pegasus Systems, Inc.
(the "Company") under and pursuant to the 1997 Amended Stock Option Plan, as
amended (the "Plan") and the [ ] Incentive [ ] Nonstatutory Stock Option
Agreement dated ________, 19 (the "Stock Option Agreement").

     2    Representations of Optionee. Optionee acknowledges that Optionee has
received, read and understood the Plan and the Stock Option Agreement and agrees
to abide by and be bound by their terms and conditions.

     3    Rights as Stockholder. Until the stock certificate evidencing such
Shares is issued (as evidenced by the appropriate entry on the books of the
Company or of a duly authorized transfer agent of the Company), no right to vote
or receive dividends or any other rights as a stockholder shall exist with
respect to the Optioned Stock, notwithstanding the exercise of the Option. The
Company shall issue (or cause to be issued) such stock certificate promptly
after the Option is exercised. No adjustment will be made 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 12 of the Plan.

          Optionee shall enjoy rights as a stockholder until such time as
Optionee disposes of the Shares or the Company and/or its assignee(s) exercises
the Right of First Refusal hereunder. Upon such exercise, Optionee shall have no
further rights as a holder of the Shares so purchased except the right to
receive payment for the Shares so purchased in accordance with the provisions of
this Agreement, and Optionee shall forthwith cause the certificate(s) evidencing
the Shares so purchased to be surrendered to the Company for transfer or
cancellation.

     4    Tax Consultation. Optionee understands that Optionee may suffer
adverse tax consequences as a result of Optionee's purchase or disposition of
the Shares. Optionee represents


                                       1
<PAGE>   20


that Optionee has consulted with any tax consultants Optionee deems advisable in
connection with the purchase or disposition of the Shares and that Optionee is
not relying on the Company for any tax advice.

     5.   Stop Transfer Orders.

          (a)  Stop-Transfer Notices. Optionee agrees that, in order to ensure
compliance with the restrictions referred to herein, the Company may issue
appropriate "stop transfer" instructions to its transfer agent, if any, and
that, if the Company transfers its own securities, it may make appropriate
notations to the same effect in its own records.

          (b)  Refusal to Transfer. The Company shall not be required (i) to
transfer on its books any Shares that have been sold or otherwise transferred in
violation of any of the provisions of this Agreement or (ii) to treat as owner
of such Shares or to accord the right to vote or pay dividends to any purchaser
or other transferee to whom such Shares shall have been so transferred.

     6.   Successors and Assigns. The Company may assign any of its rights under
this Agreement to single or multiple assignees, and this Agreement shall inure
to the benefit of the successors and assigns of the Company. Subject to the
restrictions on transfer herein set forth, this Agreement shall be binding upon
Optionee and his or her heirs, executors, administrators, successors and
assigns.

     7.   Interpretation. Any dispute regarding the interpretation of this
Agreement shall be submitted by Optionee or by the Company forthwith to the
Administrator of the Plan, which shall review such dispute at its next regular
meeting. The resolution of such a dispute by the Administrator shall be final
and binding on the Company and on Optionee.

     8.   Governing Law; Severability. This Agreement shall be governed by and
construed in accordance with the laws of the State of Texas excluding that body
of law pertaining to conflicts of law. Should any provision of this Agreement be
determined by a court of law to be illegal or unenforceable, the other
provisions shall nevertheless remain effective and shall remain enforceable.

     9.   Notices. Any notice required or permitted hereunder shall be given in
writing and shall be deemed effectively given upon personal delivery or upon
deposit in the United States mail by certified mail, with postage and fees
prepaid, addressed to the other party at its address as shown below beneath its
signature, or to such other address as such party may designate in writing from
time to time to the other party.

     10.  Further Instruments. The parties agree to execute such further
instruments and to take such further action as may be reasonably necessary to
carry out the purposes and intent of this Agreement.

     11.  Delivery of Payment. Optionee herewith delivers to the Company the
full Exercise Price for the Shares.

     12.  Lock-Up Period. Optionee hereby agrees that if so requested by the
Company or any representative of the underwriters (the "Managing Underwriter")
in connection with any registration of the offering of any securities of the
Company under the Securities Act, Optionee shall not sell or otherwise transfer
any Shares or other securities of the Company during the 180-day period (or such
longer period as may be requested in writing by the Managing Underwriter and
agreed to in writing by the Company) (the "Market Standoff Period") following
the effective date of a registration statement of the Company filed under the
Securities Act; provided, however, that such restriction shall apply only to the
first registration statement of the Company to become effective under the
