of the Plan, the maximum aggregate number of Shares which may be optioned and
sold under the Plan is 1,200,000 Shares (the "Pool") of Common Stock. The Shares

reason without having been exercised in full, the unpurchased Shares, which were
subject thereto, shall, unless the Plan shall have been terminated, become
available for future grant under the Plan.

         4.       Administration of and Grants of Options under the Plan.

                  (a) Administrator. Except as otherwise required herein, the
Plan shall be administered by the Board.

                  (b) Procedure for Grants. The provisions set forth in this
Section 4(b) shall not be amended more than once every six months, other than to
comply with changes in the Code, the Employee Retirement Income Security Act of
1974, as amended, or the rules thereunder. All grants of Options hereunder shall
be automatic and non-discretionary and shall be made strictly in accordance with
the following provisions:

                           (i) No person shall have any discretion to select
which Outside Directors shall be granted Options or to determine the number of
Shares to be covered by Options granted to Outside Directors.

                           (ii) Each new Outside Director who shall first join
the Board on or after February 1, 1993, shall automatically be granted an Option
to purchase 15,000 Shares upon the date on which such person first becomes an
Outside Director, whether through election by the stockholders of the Company,
appointment by the Board to fill a vacancy, or termination of employment by the
Company while remaining as a Director (a "One-Time Grant"). In addition, on
March 1, 1994, and on each March 1 thereafter until March 1, 1998, during the
term of this Plan, each Outside Director who shall have been an Outside Director
for at least six (6) months as of such date shall automatically receive an
Option to purchase 3,000 Shares, and on March 1, 1999, and on each March 1
thereafter during the term of this Plan, each Outside Director who shall have
been an Outside Director for at least six (6) months as of such date shall
automatically receive an Option to purchase 7,000 Shares (an "Annual Grant").
Notwithstanding any other provision in the Plan, the amount of the Annual Grant
and the One-Time Grant shall not be adjusted in the event of any stock split,
reverse stock split, recapitalization or other change in the capitalization of
the Company, unless otherwise specifically provided by the Board.

                                                                               3
<PAGE>   4
                           (iiii) The terms of each Option granted hereunder
shall be as follows:

                                    (A) the term of the Option shall be five (5)
years;

                                    (B) the Option shall be exercisable only
while the Outside Director remains a Director of the Company, except as set
forth in Section 8 hereof;

                                    (C) the exercise price per Share shall be
100% of the Fair Market Value per Share on the date of grant of the Option;

                                    (D) each Annual Grant and One-Time Grant
shall become exercisable in installments cumulatively as to one-third of the
Optioned Stock on each anniversary of the date of grant, so that 100% of the
Optioned Stock granted under any such grant shall be exercisable in full three
(3) years after the date of grant of the Option, assuming in each case
Continuous Status as a Director.

                           (iv) In the event that any Option granted under the
Plan would cause the number of Shares subject to outstanding Options plus the
number of Shares previously purchased upon exercise of Options to exceed the
Pool, then each such automatic grant shall be for that number of Shares
determined by dividing the total number of Shares remaining available for grant
by the number of Outside Directors entitled to receive Options on the grant
date. No further grants shall be made until such time, if any, as additional
Shares become available for grant under the Plan through action of the
shareholders to increase the number of Shares which may be issued under the Plan
or through cancellation or expiration of Options previously granted hereunder.

                  (c) Powers of the Board. Subject to the provisions and
restrictions of the Plan, the Board shall have the authority, in its discretion:
(i) to determine, upon review of relevant information and in accordance with
Section 2(i) of the Plan, the Fair Market Value of the Common Stock; (ii) to
interpret the Plan; (iii) to prescribe, amend and rescind rules and regulations
relating to the Plan; (iv) to authorize any person to execute on behalf of the
Company any instrument required to effectuate the grant of an Option or Common
Stock Equivalent previously granted hereunder; and (v) to make all other
determinations deemed necessary or advisable for the administration of the Plan.

                  (d) Effect of Board's Decision. All decision determinations
and interpretations of the Board shall be final.

         5.  Common Stock Equivalents.

                  (a) Award of Common Stock Equivalents. On the first business
day of each of the Company's fiscal quarters during the term of this Plan
(beginning on April 1, 1999), the Company shall grant to each Outside Director
that number of Common Stock Equivalents equal in value to the Outside Director's
Quarterly Compensation for such quarter divided by the Fair Market Value of the
Common Stock on such day. Commencing with the January 2000 payment, each Outside
Director

                                                                               4
<PAGE>   5
may elect to receive up to 50% of his or her compensation in cash and the
balance in Common Stock Equivalents. The Common Stock Equivalents granted to
each Outside Director shall be calculated based upon the percentage of
compensation such director is receiving in Common Stock Equivalents.

                  (b) Bookkeeping Account; Nontransferability. The number of
Common Stock Equivalents awarded pursuant to Section 5(a) to each Outside
Director shall be credited to a bookkeeping account established in the name of
the Outside Director. The Company's obligation with respect to such Common Stock
Equivalents shall not be funded or secured in any manner. An Outside Director's
right to receive Common Stock Equivalents may not be assigned or transferred,
voluntarily or involuntarily, except as expressly provided herein.

                  (c) Dividends. If the Company pays a cash dividend with
respect to the Shares at any time while Common Stock Equivalents are credited to
an Outside Director's account, there shall be credited to the Outside Director's
account additional Common Stock Equivalents equal to (i) the dollar amount of
the cash dividend the Outside Director would have received had he or she been
the actual owner of the Shares to which the Common Stock Equivalents then
credited to the Outside Director's account relate, divided by (ii) the Fair
Market Value of one Share on the dividend payment date.

                  (d) Conversion. As soon as practicable following the date on
which an Outside Director's Continuous Status as a Director terminates for any
reason, or as otherwise provided herein, the Company shall deliver to the
Outside Director (or his or her designated beneficiary or estate) a number of
Shares equal to the whole number of Common Stock Equivalents then credited to
the Outside Director's account, or at the Company's option, shall have the
Shares credited to an account for the Director with a brokerage firm of the
Company's choosing.

                  (e) Stockholder Rights. An Outside Director (or his or her
designated beneficiary or estate) shall not be entitled to any voting or other
stockholder rights as a result of the credit of Common Stock Equivalents to the
Outside Director's account, until certificates representing Shares are delivered
to the Outside Director (or his or her designated beneficiary or estate) until
conversion of the Outside Director's Common Stock Equivalents to Shares pursuant
to Section 5(d).

         6. Eligibility. Options and Common Stock Equivalents may be granted
only to Outside Directors. All Options shall be granted automatically in
accordance with the terms set forth in Section 4(b) hereof. All Common Stock
Equivalents shall be granted automatically in accordance with the terms set
forth in Section 5 hereof An Outside Director who has been granted an Option
may, if he or she is otherwise eligible, be granted an additional Option or
Options in accordance with such provisions.

                  The Plan shall not confer upon any Optionee any right with
respect to continuation of service as a Director or nomination to serve as a
Director, nor shall it interfere in any way with any rights which the Director
or the Company may have to terminate his or her directorship at any time.

         7. Term of Plan. The Plan shall become effective upon the earlier to
occur of its

                                                                               5
<PAGE>   6
adoption by the Board or its approval by the stockholders of the Company as
described in Section 16 of the Plan. It shall continue in effect until March 31,
2003, unless sooner terminated under Section 12 of the Plan.

         8. Consideration. 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 Board and may consist entirely of (i) cash, (ii) check, (iii)
promissory note, (iv) other shares which have a Fair Market Value on the date of
surrender equal to the aggregate exercise price of the Shares as to which said
Option shall be exercised and which, in the case of Shares acquired upon
exercise of an option, have been owned by the Optionee for more than 12 months
on the date of surrender, (v) delivery of a properly executed exercise notice
together with irrevocable instructions to a broker to promptly deliver to the
Company the amount of sale or loan proceeds required to pay the exercise price,
(vi) delivery of an irrevocable subscription agreement for the Shares which
irrevocably obligates the Optionee to take and pay for the Shares not more than
12 months after the date of delivery of the subscription agreement, (vii) any
combination of the foregoing methods of payment, or (viii) such other
consideration and method of payment for the issuance of Shares to the extent
permitted under applicable law.

         9.       Exercise of Option.

                  (a) Procedure for Exercise; Rights as a Stockholder. Any
Option granted hereunder shall be exercisable at such times as are set forth in
Section 4(b) hereof; provided, however, that no Options shall be exercisable
until stockholder approval of the Plan in accordance with Section 17 hereof has
been obtained.

                  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 consist of any consideration and method of payment
allowable under 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. A share
certificate for the number of Shares so acquired shall be issued to the Optionee
as soon as practicable after 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 11 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.

                                                                               6
<PAGE>   7
                  (b) Termination of Continuous Status as a Director. In the
event an Optionee's Continuous Status as a Director terminates (other than upon
the Optionee's death or total and permanent disability (as defined in Section
22(e)(3) of the Code)), the Optionee may exercise his or her Option, but only
within 90 days from the date of such termination, and only to the extent that
the Optionee was entitled to exercise it at the date of such termination (but in
no event later than the expiration of its five-year term). To the extent that
the Optionee was not entitled to exercise an Option at the date of such
termination, and to the extent that the Optionee does not exercise such Option
(to the extent otherwise so entitled) within the time specified herein, the
Option shall terminate.

                  (c) Disability of Optionee. In the event Optionee's Continuous
Status as a Director terminates as a result of total and permanent disability
(as defined in Section 22(e)(3) of the Code), the Optionee may exercise his or
her Option, but only within six months from the date of such termination, and
only to the extent that the Optionee was entitled to exercise it at the date of
such termination (but in no event later than the expiration of its five-year
term). To the extent that the Optionee was not entitled to exercise an Option at
the date of termination, or if he or she does not exercise such Option (to the
extent otherwise so entitled) within the time specified herein, the Option shall
terminate.

                  (d) Death of Optionee. In the event of an Optionee's death
while a Director, the Optionee's estate or a person who acquired the right to
exercise the Option by bequest or inheritance may exercise the Option, but only
within one year following the date of death, and only to the extent that the
Optionee was entitled to exercise it at the date of death (but in no event later
than the expiration of its five-year term). To the extent that the Optionee was
not entitled to exercise an Option at the date of death, and to the extent that
the Optionee's estate or a person who acquired the right to exercise such Option
does not exercise such Option (to the extent otherwise so entitled) within the
time specified herein, the Option shall terminate.

         10. Non-Transferability of Options. The Option and Common Stock
Equivalents may not be sold, pledged, assigned, hypothecated, transferred or
disposed of in any manner other than by will, by the laws of descent or
distribution or pursuant to a qualified domestic relations order, and may be
exercised, during the lifetime of the Optionee, only by the Optionee or a
permitted transferee.

         11.      Adjustments.

                  (a) Changes in Capitalization. In the event that the stock of
the Company is changed by reason of any stock split, reverse stock split,
recapitalization, or other change in the capital structure of the Company, or
converted into or exchanged for other securities as a result of any merger,
consolidation or reorganization, or in the event that the outstanding number of
shares of stock of the Company is increased through payment of a stock dividend,
appropriate proportionate adjustments shall be made in the number and class of
shares of stock subject to the Plan, the number and class of shares subject to
any Option and Common Stock Equivalent outstanding under the Plan, the number of
Common Stock Equivalents credited to an Outside Director's account under Section
5(b) and the exercise price of any such outstanding Option; provided, however,
that the

                                                                               7
<PAGE>   8
Company shall not be required to issue fractional shares as a result of
any such adjustment. Any such adjustment shall be made upon approval by the
Board, whose determination shall be conclusive. If there is any other change in
the number or type of the outstanding shares of stock of the Company, or of any
other security into which such stock shall have been changed or for which it
shall have been exchanged, and if the Board in its sole discretion determines
that such change equitably requires an adjustment in the Options then
outstanding under the Plan, such adjustment shall be made in accordance with the
determination of the Board. No adjustments shall be required by reason of the
issuance or sale by the Company for cash or other consideration of additional
shares of its stock or securities convertible into or exchangeable for shares of
its stock.

                  (b) Change in Control. In the event of a "Change in Control"
of the Company, as defined in paragraph (c) below, then the following provisions
shall apply:

                           (i) Any Option outstanding on the date of such Change
in Control ("Outstanding Option") that is not yet exercisable and vested on such
date shall become fully exercisable and vested;

                           (ii) Each Outstanding Option shall be assumed by the
successor corporation (if any) or by a Parent or Subsidiary of the successor
corporation (if any);

                           (iii) Each Outstanding Option shall remain
exercisable by the Optionee for a period of at least ninety (90) days from the
date of the Change in Control;

                           (iv) Each Optionee with an Outstanding Option shall
be provided with written notice of the period of exercisability provided for in
subsection (b)(iii) above promptly after the date of the Change in Control by
the Company or by the entity surviving after the Change in Control.

                           (v) Each outstanding Common Stock Equivalent shall
convert into Shares (as provided in Section 5(d)) immediately prior to the
Change in Control.

                  (c) Definition of "Change in Control". For purposes of this
Section, a "Change in Control" means the happening of any of the following:

                           (i) when any "person," as such term is used in
Sections 13(d) and 14(d) of the Exchange Act (other than the Company, a
Subsidiary or a Company employee benefit plan, including any trustee of such
plan acting as trustee) is or becomes the "beneficial owner" (as defined in Rule
13d-3 under the Exchange Act), directly or indirectly, of securities of the
Company representing more than fifty (50%) of the combined voting power of the
Company's then outstanding securities entitled to vote generally in the election
of directors; or

                                                                               8
<PAGE>   9
                           (ii) a merger or consolidation of the Company with
any other corporation, other than a merger or consolidation which would result
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 entity) at least fifty percent (50%) of
the total voting power represented by the voting securities of the Company or
such surviving entity outstanding immediately after such merger or
consolidation; or

                           (iii) the stockholders of the Company approve an
agreement for the sale or disposition by the Company of all or substantially all
the Company's assets; or

                           (iv) a change in the composition of the Board
occurring as a result of any one meeting of the stockholders of the Company, as
a result of which fewer than a majority of the directors are Incumbent
Directors. "Incumbent Directors" shall mean directors who either are (A)
directors of the Company as of the date the Plan is approved by the
stockholders, or (B) elected, or nominated for election, to the Board of
Directors of the Company with the affirmative votes of at least a majority of
the Incumbent Directors at the time of such election or nomination (but shall
not include an individual whose election or nomination is in connection with an
actual or threatened proxy contest relating to the election of directors to the
Company).

         12.      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 any other applicable law or regulation), the Company shall
obtain stockholder approval of any Plan amendment in such a manner and to such a
degree as required.

                  (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.

         13. Time of Granting Options. The date of grant of an Option shall, for
all purposes, be the date determined in accordance with Section 4(b) hereof.
Notice of the determination shall be given to each Outside Director to whom an
Option is so granted within a reasonable time after the date of such grant.

         14. 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, state securities laws and the requirements of any stock exchange or
market system upon which the Shares may then be listed, 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.

                  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.

         15. Reservation of Shares. 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.

         16. Option Agreement. Options shall be evidenced by written option
agreements in such form, as the Board shall approve.

         17. Stockholder Approval. Continuance of the Plan shall be subject to
approval by the stockholders of the Company at or prior to the first annual
meeting of stockholders held subsequent to the first granting of an Option
hereunder. Such stockholder approval shall be obtained in the degree and manner
required under applicable state and federal law.

                                                                              10<PAGE>   1
                     ADDENDUM NO. 1 TO EMPLOYMENT AGREEMENT

     This Addendum No. 1 (the "Addendum") is entered into as of April 14, 2000,
by and between Manuel A. Fernandez, an individual ("Executive") and Gartner
Group, Inc. a Delaware corporation (the "Company").

                                    RECITALS

     A. Executive and the Company are parties to an Employment Agreement dated
as of November 12, 1998 (the "Employment Agreement"), which provides for
Executive to serve as Chairman of the Board through October 1, 2000 (the
"Employment Term").

     B. The Company and Executive desire to provide for Executive's continuing
service to the Company following the Employment Term, upon and subject to the
terms and conditions set forth herein.

                                    AGREEMENT

     THEREFORE, in consideration of the mutual covenants contained herein, the
parties hereby agree as follows:

     1. Continuation of Agreement. Following the Employment Term, Executive
shall continue to serve as Chairman of the Board through the Extended Term
specified in Section 3. Executive will report to the Board of Directors and will
render such services consistent with such role as the Executive and the Board of
Directors may agree from time to time.

     2. Board of Directors. During the Extended Term, the Company shall include
Executive on the Company's slate of nominees to be elected to the Board of
Directors of the Company at each annual meeting of stockholders of the Company,
shall use its best efforts to cause Executive to be elected to the Board of
Directors at such meetings, and if elected shall use its best efforts to cause
Executive to continue to serve on the Board of Directors until Executive's
successor is duly elected and qualified. Upon termination of the Extended Term
for any reason, Executive shall promptly resign as director of the Company.

     3. Term.

         (a) Extended Term. Following the Employment Term, and without further
action by the Company or Executive, Executive shall continue service as Chairman
of the Board. The service of Executive as Chairman of the Board pursuant to this
Addendum shall continue through October 1, 2001 (the "Extended Term"), unless
extended or earlier terminated as provided in this Addendum.

         (b) Further Extensions. The Extended Term may be further extended upon
mutual agreement of Executive and the Company for additional one-year periods.
Any such extension shall be on the terms and conditions set forth in the
Employment Agreement, as
<PAGE>   2

modified by this Addendum, except that the Extension Compensation (as defined in
Section 4) for each extension period shall be $16,666.67 per month and the
target bonus shall be $100,000 and except that the Change in Control payments
described in Section 8(d)(B) hereof equal to three (3) times certain amounts
shall not be available to Executive.

     4. Compensation.

         (a) Extension Compensation. As compensation for the services rendered
by Executive under this Addendum, the Company shall pay to Executive continued
salary of $33,333 per month ("Extension Compensation") during the Extended Term.

         (b) Option Exercise. All options and other exercisable rights held by
Executive, other than those options and rights which have an exercise price less
than the current fair market value of the securities for which they are
exercisable on the date of this Agreement, shall remain exercisable for the
longest period available for a continuing employee under the applicable plan or
agreement, regardless of whether or not Executive remains employed by the
Company. The Company represents that it has obtained all necessary approvals of
the Committee under the applicable stock option or rights plan to the extent
required to enforce this paragraph.

     5. Bonus. In addition to his Extension Compensation, Executive shall be
entitled during the Extended Term to participate in the Company's executive
bonus program. The annual target bonus shall be established by the Board of
Directors or its Compensation Committee, in the discretion of the Board or such
Committee, and shall be payable at the same time and in the same proportion as
bonus may be payable to the President and Chief Executive Officer of the
Company. Executive's target bonus for the fiscal year ending September 30, 2000
has previously been set at $400,000, with a maximum bonus of $800,000.
Executive's target bonus for the fiscal year ending September 30, 2001 shall be
$400,000, with a maximum bonus of $800,000. By way of example, if the President
were awarded a 100% bonus for the 2000 fiscal year, then Executive shall receive
a 100% bonus, or $400,000. If the President were awarded a 200% bonus for the
2000 fiscal year, then Executive shall receive a 200% bonus, or $800,000. This
method of calculating Executive's bonus shall apply to the bonus payable to
Executive during the Employment Term under the Employment Agreement as well as
to the bonus payable to Executive during the Extended Term.

     6. Executive Benefits.

         (a) Employee and Executive Benefits. Executive will be entitled during
the Extended Term to receive all benefits provided to executives and employees
of the Company generally from time to time, including medical, dental, life
insurance and long-term disability, and the executive split-dollar life
insurance and executive disability plan, as well as Executive's auto benefit
program (with the full cost of operation not to exceed $15,000 per year) so long
as and to the extent the same exist; provided, that in respect to each such plan
Executive is otherwise eligible and insurable in accordance with the terms of
such plans.

         (b) Vacation, Sick Leave, Sabbaticals and Holidays. Executive shall be
entitled during the Extended Term to vacation, sick leave, sabbatical leave and
vacation in

                                      -2-
<PAGE>   3

accordance with the policies of Gartner and its subsidiaries as they exist from
time to time. Executive understands that under the current policy he will
receive six (6) weeks vacation per calendar year. Vacation which is not used
during any calendar year will not roll over to the following year.

         (c) Office Support, Administrator. Executive shall be entitled to an
office in Fort Myers, Florida, comparable to his office on the date of this
Addendum, the services of a full-time administrative assistant, and support
services customary for a person of Executive's position, all at Company expense,
during the Employment Term and Extended Term.

         (d) Benefits as Director. Executive shall receive the benefits granted
to outside directors, other than additional monetary compensation and stock
options, for so long as he remains on the Board of Directors of the Company.

     7. Stock Options. The Company shall, promptly following the execution and
delivery of this Agreement, grant the Executive a non-qualified stock option to
purchase up to 100,000 shares of the Company's Class A Common Stock with an
exercise price equal to the fair market value of the Company's Class A Common
Stock on the date of issuance, as determined by the Compensation Committee. Such
option shall vest one quarter on the first anniversary of the date of this
Addendum and the balance in equal amounts on a monthly basis for the next 36
months following such first anniversary. Such option shall be subject to the
other terms and conditions adopted by the Company for its executive stock
options, and if the Company has multiple plans, then the terms and conditions
set forth in the plan under which the President has received options in 1999;
provided, however, that whether or not the same is the practice for the Company
in granting executive stock options, the options granted pursuant to this
Section 7 shall remain exercisable for the maximum permitted time period (but
not to exceed ten (10) years in any event), regardless of whether or not
Executive continues to provide services to the Company hereunder and regardless
of the reason for any termination of Executive's engagement.

     8. Severance Benefits. Executive shall be entitled during the Extended Term
to the severance benefits set forth in this Section 8.

         (a) Salary Continuation. If the Company terminates the services of
Executive involuntarily and without Business Reasons or a Constructive
Termination occurs, or Executive shall become unable to perform his duties as a
result of incapacity, which gives rise to termination of employment for
Disability, or Executive voluntarily terminates his employment or resigns as
Chairman of the Board, or Executive's employment is terminated because of death,
then in any such case (other than following a Change in Control or in
contemplation of a pending Change in Control, which are governed by Section 8(d)
below), Executive shall be entitled to receive (A) Extended Compensation through
October 1, 2001, payable in accordance with the Company's regular payroll
schedule as in effect from time to time, (B) on the Termination Date, 100% of
Executive's target bonus for the fiscal year in which the Termination Date
occurs (plus any unpaid bonus from the prior fiscal year), and (C) following the
end of the fiscal year in which the Termination Date occurs and management
bonuses have been determined, a pro rata share (based on the proportion of the
fiscal year during which Executive provided services to the Company) of the
bonus that would have been payable to Executive under Section 5 in excess of
100% of Executive's target bonus for the fiscal year.

                                      -3-

         (b) Continuation of Benefits. Executive shall be entitled to
continuation of (i) group health benefits and life and disability pursuant to
the Company's standard programs as in effect from time to time (or continuation
by the Company of substantially similar group health benefits as in effect at
the Termination Date, through a third party carrier, at Company's election) for
Executive, his spouse and any children for so long as they are under the age of
19 (25, if a full-time student) and (ii) life and disability insurance coverage
pursuant to the Company's programs as in effect for Executive on the date of
this Addendum (or continuation by the Company of substantially similar life and
disability insurance coverage, at Company's election), in each instance until
such time as Executive reaches or would have reached the age of 65. This
provision shall apply regardless of the reason for termination or resignation
and shall further apply if the Employment Agreement or this Addendum expires by
its terms.

         (c) Stock Options and Related Rights. If the Company terminates the
services of Executive involuntarily and without Business Reasons or a
Constructive Termination occurs, or Executive shall become unable to perform his
duties as a result of incapacity, which gives rise to termination of employment
for Disability, or Executive voluntarily terminates his employment or resigns as
Chairman of the Board, or Executive's employment is terminated because of death,
then in any such case (other than following a Change in Control or in
contemplation of a pending Change in Control, which are governed by Section 8(d)
below), Executive shall be entitled to receive acceleration in full of vesting
of all outstanding stock options, TARPs and other equity arrangements subject to
vesting and held by Executive (and in this regard, all options and other
exercisable rights held by executive shall remain exercisable for the period
specified in Section 4(b) of this Addendum).

         (d) Change in Control. If a Change in Control occurs, whether during
the Employment Term or the Extended Term, then in lieu of the benefits set forth
in Section 7(c) of the Employment Agreement, Executive shall be entitled to
receive (A) salary or Extension Compensation, as the case may be, and vacation
and sabbaticals accrued through the Termination Date (B) an amount equal to
three (3) times the greater of (i) Executive's average annual compensation
(salary or Extension Compensation plus bonus) for those three of the last seven
fiscal years in which such compensation was highest or (ii) $800,000, whichever
is greater, payable immediately upon the Change in Control, (C) any unpaid bonus
from the prior fiscal year, payable immediately upon the Change in Control, (D)
acceleration in full of vesting of all outstanding stock options, TARPs and
other equity arrangements subject to vesting and held by Executive (and in this

continuing employee under the applicable plan or agreement, regardless of the
reasons for termination, (E) continuation of (i) group health benefits and life
and disability pursuant to the Company's standard programs as in effect from
time to time (or continuation by the Company of substantially similar group

so long as they are under the age of 19 (25, if a full-time student) and (ii)
life and disability insurance coverage pursuant to the Company's programs as in

would have reached the age of 65, (F) continuation of Executive's auto benefits
for one year following the Termination Date, (G) forgiveness by the Company of
all outstanding principal and interest

due to the Company under indebtedness incurred by Executive to purchase shares
of capital stock of the Company, and (H) no other compensation, severance or
other benefits. Notwithstanding the foregoing, however, if Executive violates
the non-competition agreement set forth in Section 12 of the Employment
Agreement during the five (5) year period following the Termination Date,
Executive shall be obligated to repay to the Company any amounts previously
received pursuant to clause (B) hereof, to the extent the same correspond to any
period following the Termination Date during which the non-competition agreement
is violated.

         (e) Other Benefits. If the Company terminates the services of Executive
involuntarily and without Business Reasons or a Constructive Termination occurs,
or Executive shall become unable to perform his duties as a result of
incapacity, which gives rise to termination of employment for Disability, or
Executive voluntarily terminates his employment or resigns as Chairman of the
Board, then in any such case, Executive shall be entitled to receive
continuation of Executive's auto benefits for one year following the Termination
Date,

         (f) Gross-Up Payment. If any payment or distribution by the Company or
any of its affiliates to or for the benefit of Executive, whether paid or
distributed pursuant to the terms of the Employment Agreement, this Addendum or
otherwise pursuant to or by reason of any plan or agreement referenced herein or
any other agreement, policy, plan, program or arrangement, including without
limitation any stock option, TARP, restricted stock or similar right, or the
lapse or termination of any restriction on, or the vesting or exercisability of,
any of the foregoing (a "Payment"), would be subject to the excise tax imposed
by Section 4999 of the Internal Revenue Code of 1986, as amended (the "Code")
(or any successor provision thereto) by reason of being considered "contingent
on a change in ownership or control" of the Company, within the meaning of
Section 280G of the Code (or any successor provision thereto) or to any similar
tax imposed by state or local law, or any interest or penalties with respect to
such tax (such tax or taxes, together with any such interest and penalties,
being hereafter collectively referred to as the "Excise Tax"), then Executive
shall be entitled to receive an additional payment or payments (collectively, a
"Gross-Up Payment"). The Gross-Up Payment shall be in an amount such that, after
payment by Executive of all taxes (including any interest or penalties imposed
with respect to such taxes), including any Excise Tax imposed upon the Gross-Up
Payment, Executive retains an amount of the Gross-Up Payment equal to the Excise
Tax imposed upon the Payment.

         (g) Retention of Equipment. Executive shall be entitled upon
termination for any reason or for no reason to retain for his personal use and
benefit his office furnishings and equipment, including without limitation
cellular phones, computers, printers, copier and similar equipment. The Company
shall assign and transfer ownership of the foregoing to Executive upon
termination without further payment by Executive to the Company.

         (h) Support Services. Executive shall be entitled to continuation of
use of technical office support services, including without limitation voice
mail, e-mail, internet access services and other connectivity services, until
such time as Executive reaches age 65.

         (i) General. Upon the death or disability of the Executive prior to age
65, benefits provided in Section 8(b) and 8(d)(E) hereunder for the benefit of
Executive, his spouse

                                      -5-
<PAGE>   6

and his children shall continue to be provided for the benefit of his spouse and
his children (within the applicable age limits) until such time as Executive
would have reached age 65.

     9. Termination Date. The definition of "Termination Date" in Section 8 of
the Employment Agreement is hereby modified to mean (i) if the Employment
Agreement is terminated on account of death, the date of death; (ii) if the
Employment Agreement is terminated for disability, the date specified in Section
8(b) of the Employment Agreement; (iii) if the Employment Agreement is
terminated by the Company, whether during the Employment Term or the Extended
Term, the date on which a notice of termination is given to Executive; (iv) if
the Employment Agreement is terminated by Executive, whether during the
Employment Term or the Extended Term, the date on which Executive delivers the
notice of termination to the Company; or (v) if the Employment Agreement expires
by its terms, then the last day of the Extended Term.

     10. Constructive Termination. In addition to the actions deemed to
constitute "Constructive Termination" under the Employment Agreement,
"Constructive Termination" shall be deemed to occur if (i) Executive shall no
longer be Chairman of the Board of the Company (other than at the end of the
Extended Term) or (ii) there is a reduction of Executive's Extension
Compensation and within the thirty (30) day period immediately following such
change or reduction Executive elects to terminate his consulting arrangement
voluntarily.

     11. Annuity Payment. Upon the termination of the Employment Agreement,
regardless of the reason therefor and regardless of whether prior to or upon its
expiration by its terms, the Company shall continue to make payments to
Executive of $200,000 per year for 10 years. Executive shall make himself
available to the Company to provide advice and guidance on a limited basis, as
the Company may reasonably request, with respect to the business of the Company
during such 10-year period, provided that such advice and guidance may be
rendered by telephone and at such times during normal business hours as may be
convenient to Executive in light of his schedule and other commitments. The
Company shall make such payments in equal monthly installments, on the first day
of each month, commencing with the month following the last day of the Extended
Term. In the event of the Executive's death prior to the end of such 10-year
period, including during the Employment Term or Extended Term, the balance of
payments under this Section shall be payable to his estate. Upon any Change in
Control, the Company shall at its expense purchase an annuity for the benefit of
Executive or his estate, as the case may be, with an annuity company reasonably
satisfactory to Executive. Such annuity shall provide Executive or his estate,
as the case may be, with the balance of payments otherwise due under this
Section, when and as due. Payment of such amounts pursuant to the annuity shall
excuse the Company from its obligations under this Section.

     12. Non-Competition Agreement. The Non-Competition Agreement set forth in
Section 12 of the Employment Agreement is hereby modified as follows:

         (a) Term. References to three (3) years shall be deemed extended to
five (5) years.

                                      -6-
<PAGE>   7

         (b) Employees. The restriction in Section 12(b)(2) on hiring another
entity or person who was an employee of the Company or any subsidiary at any
time during the Employment Period shall be limited to current employees of the
Company at the time of hiring.

         (c) Venture Funds. Nothing in Section 12 shall preclude or limit
Executive's ability to invest, manage or otherwise participate in SI Ventures
Affiliates Fund, L.P., SI Fund I, L.L.C., SI Services Company, L.L.C., SI
Venture Management I, L.L.C. or any similar venture capital fund, management
company, service company or similar company that invests generally in
information technologies businesses.

     13. Survival of Employment Agreement. As modified by this Addendum, the
Employment Agreement shall remain in full force and effect. References herein to
the "Employment Agreement" shall mean the Employment Agreement as modified by
this Addendum, except as the context otherwise requires. Those provisions that
by their terms apply to periods following the Employment Term or the Extended
Term shall survive the termination of the Employment Agreement.

     14. Counterparts. This Addendum may be executed in counterparts, each of
which shall be deemed an original, but all of which together will constitute one
and the same instrument.

     15. Capitalized Terms. Capitalized terms used without definition in this
Addendum shall have the meanings ascribed to them in the Employment Agreement.

     IN WITNESS WHEREOF, each of the parties has executed this Addendum, in the
case of the Company by its duly authorized officer, as of the day and year first
above written.
