                                                                       Employee Share
                                                                       of Net Proceeds
                                                                       Available for Distribution
                  Acquisition Price                                    to the Series B Holders
                  -----------------                                    --------------------------

<S>                                                                    <C>
                  Below $10 million                                             0%
                  $10 to less than $20 million                                  6%
                  $20 to less than $30 million                                  8%
                  $30 to less than $40 million                                  10%
                  $40 to less than $60 million                                  12%
</TABLE>

         The employee share under this Acquisition Bonus Program ("ABP") shall
be calculated as a percentage of the net aggregate proceeds available for
distribution to the holders of the Series B Convertible Preferred Stock (the
"SERIES B HOLDERS") of AirNet Communications Corporation (the "COMPANY") as the
liquidation preference amount upon a Sale of the Company (defined below) as
shown above and in no event shall the amount allocated to the ABP exceed
$7,200,000. By way of illustration, if the Acquisition Price is $31,000,000 and
the Net Proceeds available for distribution to the Series B Holders is
$29,000,000, then $2,900,000 would be allocated to the ABP.

         The obligation of the Series B Holders to fund the ABP is contained in
the Agreement to Allocate Proceeds dated as of October 31, 2001 by and among the
Company and the Series B Holders. If the Series B Holders receive consideration
other than cash in connection with the Sale of the Company (as defined below)
then the ABP may be funded in-kind in the same proportion the Series B Holders
receive in-kind consideration in connection with the Sale of the Company.
Whether in cash or in-kind the Company shall withhold payroll taxes at the time
of the distribution of the Net Proceeds available for distribution in the
minimum amount required by law (unless an Eligible Employee requests additional
withholding) in compliance with all applicable Internal Revenue Service ("IRS")
and other regulations. If the distribution is other than in cash then the
Company shall withhold stock or property equal to the withholding amount at the
transaction value in compliance with IRS regulations or other regulations. The
Company shall remit payment to the IRS and applicable taxing authorities in
accordance with applicable IRS and other regulations.
<PAGE>
II.      MANAGEMENT AND EMPLOYEE BONUS PROGRAM.

         In addition to the amounts credited to the ABP, if the Net Proceeds
reach the thresholds listed below, then up to ten and one half percent (10.5%)
of the Net Proceeds to Common Stockholders will be allocated by the Company to
the Management and Employee Bonus Program ("MBP").

                                                              Stockholders Credited to MBP
                                                              ----------------------------
<S>                                                           <C>

                  $10 to less than $20 million                         6%
                  $20 to less than $30 million                         8%
                  Over $30 million                                     10.5%
</TABLE>

If the Common Stockholders receive consideration other than cash in connection
with the Sale of the Company (as defined below) then the MBP may be funded
in-kind in the same proportion the Common Stockholders receive in-kind
consideration in connection with the Sale of the Company. By way of
illustration, if the Acquisition Price is $31,000,000 and the Net Proceeds to
Common Stockholders is $29,000,000, then $3,045,000 would be allocated to the
MBP.

Whether in cash or in-kind the Company shall withhold payroll taxes at the time
of the distribution of the Net Proceeds available for distribution in the
minimum amount required by law (unless an Eligible Employee requests additional
withholding) in compliance with all applicable IRS and other regulations. If the
distribution is other than in cash then the Company shall withhold stock or
property equal to the withholding amount at the transaction value in compliance
with IRS regulations or other regulations. The Company shall remit payment to
the IRS and applicable taxing authorities in accordance with applicable IRS and
other regulations.

"NET PROCEEDS TO COMMON STOCKHOLDERS" shall mean the Net Proceeds less the
liquidation preference actually paid to the Company's Series B Holders and less
the amount allocated to the ABP. "NET PROCEEDS" shall mean the net sales
proceeds available for distribution to the Company's stockholders in connection
with the Sale of the Company, after deducting transaction expenses relating
directly to the Sale of the Company including attorneys fees, accounting fees,
and underwriting or brokerage commissions. "SALE OF THE COMPANY" shall mean (i)
a sale or exchange of all or substantially all of the assets (including a sale,
disposition, or exchange in a liquidation) or (ii) a sale or exchange of all or
substantially all of the outstanding capital stock of the Company resulting in a
Change of Control of the Company, or (iii) a merger, consolidation or other
business combination (excluding any issuance of previously un-issued voting
securities from the Company in connection with an investment in the Company by a
Series B Holder or any third party) resulting in a Change of Control of AirNet
Communications Corporation, as a result of which AirNet Communications
Corporation is not the continuing or surviving corporation. "CHANGE OF CONTROL"
means the acquisition by any individual, entity or group of 50% or more of the
outstanding voting securities of the Company or 50% or more of the

                                      -2-
<PAGE>
combined voting power of then outstanding voting securities of the Company
entitled to vote generally in the election of directors. "ACQUISITION PRICE"
means the aggregate sum of money and/or fair market value of property (valued as
of the date of closing) to be paid by an acquiring party to the Company or to
its stockholders in connection with a Sale of the Company. For purposes of the
Bonus Program, if the acquiring party is then a current stockholder or an
affiliate of a current stockholder ("CURRENT STOCKHOLDER ACQUIRING PARTY") which
is (a) acquiring the assets of the Company in a transaction in which the Current
Stockholder Acquiring Party receives no distribution of money or property with
respect to its stock or a distribution which is less than the per-share amount
received by other stockholders holding the same class or series of shares, (b)
engaging in a merger, consolidation or other business combination with AirNet
Communications Corporation in which AirNet Communications Corporation is not the
continuing or surviving corporation and in which the Current Stockholder
Acquiring Party receives no money or property in exchange for its shares or an
amount of money or property which is less than the per-share amount received by
other stockholders holding the same class or series of shares, or (c) acquiring
shares of Company stock from stockholders but not from itself or the current
stockholder affiliated with the Current Stockholder Acquiring Party, the amount
of the Acquisition Price shall include the value of the shares of Company stock
held by such Current Stockholder Acquiring Party based on the same value per
share that will be paid or distributed to stockholders owning the same class or
series of shares.

Should a Current Stockholder Acquiring Party be the purchaser in a Sale of the
Company and that party does not receive, or waives its right to receive, all or
any portion of the purchase price otherwise payable to stockholders, then and
only in that event, the Net Sales Proceeds to Common Stockholders shall include
the value of the shares of Company stock held by such Current Stockholder
Acquiring Party based on the same value per share that will be paid or
distributed to stockholders owning the same class or series of shares (the "
Value Adjustment"). The payment of bonuses applicable to the Value Adjustment is
an obligation of the Company and shall not reduce the amount of Net Sales
Proceeds from the Sale of the Company otherwise payable to stockholders other
than the Eligible Employees hereunder.
..

THE ABP AND THE MBP SHALL BE ADMINISTERED AS FOLLOWS:

         1. Only employees (the "ELIGIBLE EMPLOYEES") designated by the
Company's Chief Executive Officer, with the review and approval of the
Compensation Committee and the Company's Board of Directors (the "BOARD") shall
be entitled to participate in the ABP and the MBP.

         2. Anything contained herein to the contrary notwithstanding, the total
amount allocable to the Eligible Employees from both the ABP and MBP shall not
exceed the greater of (i) ten and one half percent (10.5%) of the Net Proceeds
or (ii) $7,200,000.

         3. In addition to Section 2, all amounts payable from the MBP to an
Eligible Employee shall be reduced by an amount equal to the value of the
difference between the exercise price of each Company common stock option
("IN-THE-MONEY OPTIONS") held by such

                                      -3-
<PAGE>
Eligible Employee that is "in-the-money" and the price of an underlying share of
the Company's common stock (the "PER-SHARE PRICE"). Such Per-Share Price shall
be calculated by dividing the Net Proceeds to Common Stockholders by the number
of shares of the Company's common stock deemed to be outstanding just prior to
the Sale of the Company, including shares underlying all In-The-Money Options.
Options exercised within the sixty (60) day period immediately preceding a Sale
of the Company shall be included in the calculation described in this Section 3.

         4. The allocation of the Net Proceeds under the ABP and MBP among the
Eligible Employees shall be at the discretion the Company's Chief Executive
Officer, with the review and approval of the Compensation Committee and the
Board of Directors. Any consideration received by an Eligible Employee pursuant
to the Bonus Program shall be in addition to, and shall not reduce or replace,
the amount of consideration such Eligible Employee may otherwise be entitled to
as a stockholder of the Company.

                         EXECUTIVE EMPLOYMENT AGREEMENT

           AGREEMENT, effective as of the 22nd day of May, 2002, by and between
Netegrity, Inc., a Delaware corporation (the "Company"), and Barry Bycoff, an
individual residing at 3 Kress Farm Road, Hingham, Massachusetts (the

terms and conditions hereinafter set forth.

           NOW, THEREFORE, in consideration of such employment and the mutual

The Executive further agrees to serve as a member and as Chairman of the Board
of Directors (the "Board") of the Company if elected or appointed to such office
in accordance with the Company's By-Laws.

           Section 2. TERM. Unless sooner terminated as provided in Section 9,
the term of employment under this Agreement shall begin on the date first

additional one (1) year terms unless terminated by the Company upon ninety (90)
days notice prior to the end of the Term or any renewal term.

           Section 3. DUTIES. The Executive shall serve as President and Chief
Executive Officer, and he shall perform additional duties consistent with the
offices of President and Chief Executive Officer as the Board of Directors of
the Corporation may reasonably assign to him from time to time. The Executive
hereby agrees to devote his full business time and best efforts to the faithful
performance of such duties and to the promotion and forwarding of the business
and affairs of the Company for the Term. Notwithstanding any provision herein to
the contrary, the Executive shall not be precluded from performing services for
another company in the capacity as a member of its Board of Directors, or for a
charitable or industry organization, provided the Executive complies fully with
the provisions of Section 8 herein below and such performance does not impair
Executive's performance of duties hereunder.

           Section 4. SALARY COMPENSATION. In consideration of the services
rendered by the Executive under this Agreement, the Company shall pay the
Executive an initial base salary (the "Base Salary") at the rate of Three
Hundred Seventy-Five Thousand Dollars ($375,000) per calendar year, which Base
Salary shall be subject to an annual review by, and to an increase in the sole
discretion of, the Compensation Committee of the Board of Directors of the
Company (the "Compensation Committee"). The Base Salary shall be paid in such
installments and at such times as the Company pays its regularly salaried key
executive employees, and the Board may change the Base Salary from time to time
in its sole discretion; provided, however, that in no event shall the Base
Salary for any calendar year be less than the Base Salary in effect for the
immediately prior calendar year.

<PAGE>

           Section 5. BONUS COMPENSATION. The Executive shall be entitled to
participate in the Company bonus plan, pursuant to which he may receive an
amount up to seventy-five percent (75%) of his Base Salary compensation
("Eligible Bonus"), such bonus to be payable in accordance with performance
milestones mutually agreed to by the Executive and the Compensation Committee
prior to each fiscal year.

           Section 6. FRINGE BENEFITS. As a key executive employee of the
Company, the Executive shall be eligible to participate in all employee fringe

following additional benefits:

           Section 7.01. PAID VACATION. The Executive shall be entitled to six
(6) weeks paid vacation per calendar year, such vacation to extend for such
periods and shall be taken at such intervals as shall be appropriate and
consistent with the proper performance of the Executive's duties hereunder. The
Company shall pay the Executive, for vacation time not taken in each year,
additional salary to cover such vacation not taken (not to exceed two (2) weeks)
in an amount equal to the product of (i) the number of vacation days not taken
(not to exceed two (2) weeks), multiplied by (ii) the Executive's daily salary
calculated with reference to the Base Salary (assuming a five-day work week).

           Section 7.02. INSURANCE COVERAGE. During the Term, the Company shall
provide the Executive with group health, dental and life insurance protection to
the same extent that it makes such protection available to its other key
executive employees. In addition to this coverage, during the effectiveness of
this Agreement, the Company shall

<PAGE>

at its expense obtain for the Executive's benefit (i) a term life insurance
policy providing coverage in an amount equal to three (3) times the Executive's
Base Salary and (ii) a disability insurance policy (the "Disability Policy")
providing coverage in an amount equal to seventy-five percent (75%) of the
Executive's Base Salary. The Disability Policy shall be owned by the Executive.
While Executive is employed by the Company, the Company shall reimburse the
Executive for all annual or other premiums owed on the Disability Policy. During
such period, the Company shall also reimburse the Executive in an amount
sufficient to reimburse Executive for any tax liability of Executive (including,
without limitation, for any state or federal income tax owed by Executive) by
reason of the Company's payment of any premium on the Disability Policy.

           Section 7.03. REIMBURSEMENT OF EXPENSES. The Company shall reimburse
the Executive for all reasonable expenses actually incurred by the Executive in

establish from time to time. The Executive shall be entitled to have his wife
accompany him on up to two (2) business trips per year at Company expense.

           Section 7.04. RETENTION BONUS. For each year that the Executive
remains an employee of the Company, he shall receive a retention bonus (the
"Retention Bonus") in an amount equal to Twenty-Five Thousand Dollars ($25,000)

           Section 7.05. OTHER BENEFITS. The Company shall reimburse the

           (a) At all times during the term of this Agreement, and thereafter
during the "Noncompete Period," as hereinafter defined, the Executive shall not,
directly or indirectly, (i) attempt to employ or retain or enter into any
contractual or business arrangement with any current or former employee,
consultant or independent contractor of the Company, or employ or hire any such
person, unless such person has not been employed by the Company, or its
predecessors, for a period in excess of one (1) year and/or (ii) induce,
influence, combine or conspire with, or attempt to induce, influence, combine or
conspire with, any of the officers, employees, independent contractors, agents,
consultants, customers or suppliers of the Company to terminate their
employment, or other relationship, with or compete against the Company or any
present or future subsidiaries or parents of the Company or other related
corporate entities with common ownership with the Company ("Affiliate") in a
business which is directly or indirectly and substantially engaged in the
development, distribution, marketing or sale of products or services being
developed, marketed, sold or otherwise provided by the Company at the time of
Executive's termination ("Competing Business").

           (b) The Executive acknowledges that his services and responsibilities
are unique in character and are of particular significance to the Company, that
the Company engages in a competitive business with a national market and that
the Executive's continued service to the Company under this Agreement is of a
high degree of importance to the Company. Therefore, during the Executive's
period of employment,

<PAGE>

the Executive will devote his available business time and best efforts to
promoting and advancing the business of the Company in accordance with Section 3
above. During the term of this Agreement and for the period of time ending one
(1) year after the Executive is no longer employed by the Company for any reason
whatsoever (the "Noncompete Period"), the Executive shall not, directly or
indirectly, engage in a Competing Business, or in any other business which the
Company or any of its subsidiaries, parents or Affiliates is actively engaged
in, except as an employee or agent of the Company, and shall not, directly or
indirectly, as owner, partner, joint venturer, employee, broker, agent,
corporate officer, principal, licensor, material shareholder or in any capacity
whatsoever, engage in any business which is a Competing Business and which
operates anywhere in the United States; PROVIDED, HOWEVER, that the record or
beneficial ownership by the Executive of one percent (1%) or less of the
outstanding publicly traded capital stock of any such company shall not be
deemed to be in violation of this Section 8, provided that the Executive is not
an officer, director or employee of such company.

           (c) The provisions of this Section 8 shall not apply to a division,
Affiliate, subsidiary or parent which is not itself a Competing Business,
notwithstanding its affiliation with a corporate organization which includes a
Competing Business.

           Section 9. TERMINATION. This Agreement shall be terminated at the
end of the Term, or earlier as follows:

           Section 9.01. DEATH. This Agreement shall terminate upon the death
of the Executive, except that the compensation provided in Section 4 shall
continue for a period of two (2) years beginning at the end of the month in
which the Executive's death occurs.

<PAGE>

           Section 9.02. PERMANENT DISABILITY. This Agreement shall terminate
upon the payment of benefit payments pursuant to Section 7.02 hereof in the
event of any physical or mental disability of the Executive determined in
accordance with the standards applicable to the disability insurance policy
referred in Section 7.02 hereof, except that the compensation provided in
Section 4 shall continue for a period of two (2) years beginning at the end of
the month in which such disability occurs, such amount to be reduced by any
insurance payments received under the disability policy.

           Section 9.03. BY THE COMPANY FOR CAUSE. The employment of the
Executive may be terminated by the Company for "Cause," as defined below, at any
time effective upon written notice to the Executive. The Company shall provide

duties reasonably assigned to him by the Board and consistent with his status as
President and Chief Executive Officer, or (ii) refused to perform duties set
forth in Sections 1 and 3 of this Agreement, which failure, refusal or breach
shall have continued for a period of at least thirty (30) days after written
notice from the Company describing such failure, refusal or breach in reasonable
detail.

           Section 9.04. BY THE COMPANY WITHOUT CAUSE. The Company may terminate

thereof and upon payments required under Section 10.02.

Officer, except in the case where Executive voluntarily relinquishes such role,
responsibility or duty in the normal course of Company management and operation;

otherwise constitutes an "excess parachute payment" within the meaning of

that constitutes an excess parachute payment, then the Executive shall be

taxes associated therewith, including any excise tax imposed by Section 4999 of
the Code.

shall make best efforts to agree upon a public statement pertaining to the
Executive's termination of employment, and the terms of said statement shall not
be subject to subsequent modification by either party unless required by law;
provided, however, that in the event the Company and the Executive are unable in

as are necessary to comply with the law or relevant regulations.

that the Executive will be indemnified and held harmless to the maximum extent
permitted by Delaware law against all expense, liability or loss (including
attorneys' fees, judgments, fines, ERISA excise taxes or penalties and amounts
paid in settlement) incurred by reason of the Executive being made a party to,
or threatened to be made a party to, or is otherwise involved in any action,
suit or proceeding, whether civil, criminal, administrative or investigative,
arising out of the Executive's role as an officer or director of the Company all
as set forth in Article VII of the Amended and Restated By-Laws of the Company
(the "By-Laws") as in effect on the date hereof. Such indemnification shall
include the right to be paid by the Company the expenses, including attorneys'
fees, incurred in defending any such proceeding, in advance of its final
disposition; PROVIDED, HOWEVER, an advancement of expenses incurred by the
Executive shall be made only upon delivery to the Company of an undertaking, by
or on behalf of the Executive, to repay all amounts so advanced if it shall
ultimately be determined by final judicial decision from which there is no
further right to appeal, that the Executive is not entitled to be indemnified
for such expenses under Article VII of the By-Laws or otherwise. The
indemnification provided under this Section 11 shall continue for the term of
ten (10) years following the effective date of termination of this Agreement for
any reason. For a period of five (5) years after the effective date of
termination of this Agreement for any reason whatsoever, the Company shall
continue to provide coverage for the

the validity of any other provision. In the event that a court of competent
jurisdiction shall determine that any provision of this Agreement or the
application thereof is unenforceable in whole or in part because of the duration
or scope thereof, the parties hereto agree that said court in making such
determination shall have the power to reduce the duration and scope of such
provision to the extent necessary to make it enforceable, and that the Agreement
in its reduced form shall be valid and enforceable to the full extent permitted
by law.
