      3.    Adoption and Administration of Plan.

            A.    This Plan shall become effective upon its adoption by the
Board of Directors; provided, however, that if the stockholders of the
Corporation shall not approve this Plan, in accordance with applicable state
law, within twelve (12) months before or after the adoption of this Plan by the

Directors or the date that this Plan is approved by the stockholders of the

            C.    The Board of Directors shall implement, interpret (except as
expressly provided in this Plan) and administer this Plan. Without limiting the
powers and authority of the Board of Directors in any respect, the Board of
Directors shall have authority (i) to construe and interpret this Plan and any

circumstances, an Option may be settled or paid in cash or other consideration;
(viii) to amend, cancel, accept the surrender of, modify or accelerate the
vesting of all or any portion of an Option, including amendments or

connection therewith.

            D.    To the extent not prohibited by the General Corporation Law of
the State of Delaware ("DGCL") or the charter or bylaws of the Corporation, the
Board of Directors may delegate any or all of its responsibilities hereunder to
the Committee, and all references herein or in any Stock Option Agreement to the
Board of Directors shall, to the extent applicable, be deemed to refer to and
include the Committee.

            E.    Any action taken by the Board of Directors (or the Committee)
with respect to the implementation, interpretation or administration of this
Plan shall be final, conclusive and binding.

      4.    Total Number of Shares of Incentive Stock.

            The number of shares of Incentive Stock which (a) may be issued in
the aggregate by the Corporation under this Plan pursuant to the exercise of
Options granted hereunder and (b) may be covered by SARs granted hereunder which
have not expired unexercised shall not be more than three million (3,000,000),
which number may be increased only by a resolution

                                      -3-
<PAGE>

adopted by the Board of Directors and approved within twelve (12) months after
such adoption by the stockholders of the Corporation in accordance with
applicable state law. Such shares of Incentive Stock may be issued out of the
authorized and unissued or reacquired Common Stock of the Corporation. Any
shares subject to an Option, SAR or portion thereof which expires or is
terminated unexercised (unless by virtue of the exercise of an Option or SAR
granted in tandem therewith) as to such shares may again be subject to an Option
or SAR under this Plan. To the extent there shall be any adjustment pursuant to
the provisions of Section 9 hereof, the aforesaid number of shares shall be
appropriately so adjusted.

      5.    Eligibility and Awards.

            A.    The Board of Directors shall determine, at any time and from
time to time, (i) any Eligible Person to whom the award of an Option or SAR may
further the purposes of this Plan in the view of the Board of Directors, (ii)
whether any Option to be awarded to an Eligible Person shall be intended as an
ISO or as a NQSO, the number of shares of Incentive Stock to be covered by such
Option or a SAR, the Exercise Price of such Option or SAR, whether such Option
contains a SAR and all other terms and conditions of such Option, (iii) the Fair
Market Value on the date of grant of the Option or SAR and (iv) the terms and
conditions of the Stock Option Agreement to evidence such Option or SAR,
including the restrictions, if any, applicable to the shares of Incentive Stock
that may be acquired upon exercise of any portion of such Option. The Board of
Directors may delegate to the appropriate officer or officers of the Corporation
the authority to prepare, execute and deliver any Stock Option Agreement
evidencing any Option or SAR granted under this Plan, provided, however, that
any such Stock Option Agreement shall be consistent with the terms and
conditions of this Plan.

            B.    For any Option intended to qualify as an ISO, in whole or in
part, (i) the Eligible Person shall then be an employee of the Corporation or a
Parent or Subsidiary, as provided in the Code, (ii) the term during which such
Option shall be in effect shall not be greater than ten (10) years [provided,
however, that the term shall not be greater than five (5) years for any Option
granted to a Controlling Participant], (iii) the Exercise Price shall not be
less than one hundred percent (100%) of the Fair Market Value on the date that
such Option is granted [provided, however, that, if an ISO shall be granted to a
Controlling Participant, the Exercise Price shall not be less than one hundred
ten percent (110%) of the Fair Market Value on the date that such Option is
granted] and (iv) such Option is exercisable only by the Participant during his
or her lifetime and shall be nontransferable by the Participant unless the Stock
Option Agreement permits such Option to be transferred by will or the laws of
descent and distribution.

            C.    As soon as practicable after the Board of Directors determines
to award an Option or SAR pursuant to Section 5(A) hereof, the appropriate
officer or officers of the Corporation shall give notice (written or oral) to
such effect to each Eligible Person designated to be awarded an Option or SAR,
which notice shall be accompanied by a copy or copies of the Stock Option
Agreement to be executed by such Eligible Person.

            D.    Upon receipt of the notice specified in Section 5(C) hereof,
an Eligible Person shall have an Option or SAR, and shall thereby become and be
a Participant, only after the due execution and delivery by such Eligible Person
and the Corporation of a Stock Option

                                       -4-
<PAGE>

Agreement (in such form and number as the officer or officers of the Corporation
shall direct) by such date and time as shall be specified in such notice (unless
waived by the Corporation).

            E.    In the event that the Corporation or any Parent or Subsidiary
assumes an option granted by another entity, which option is to be covered by
this Plan and upon the exercise of which shares of Incentive Stock are to be
issued, the terms and conditions of such option shall remain unchanged (except
the exercise price and the number and nature of shares issuable upon exercise
thereof, which shall be adjusted appropriately in accordance with the Code, and
references to such other entity, which shall be deemed to refer to the
Corporation). In the event that the Board of Directors elects to grant an Option
or SAR under this Plan to replace an option or SAR granted by another entity
(rather than assume such option or SAR), the holder of such option or SAR shall
be eligible to receive such replacement Option or SAR, which may be granted with
a similarly-adjusted Exercise Price.

      6.    Exercise and Termination of Options.

            A.    An Option of a Participant may be exercised during the period
such Option is in effect and as set forth herein and in the Stock Option
Agreement, and only if compliance with all applicable Federal and state
securities laws can be effected. An Option may be exercised only by (i) the
Participant's completion, execution and delivery to the Corporation of a notice
of such Participant's exercise of such Option and an "investment letter" (if
required by the Corporation) as supplied by the Corporation and (ii) the payment
to the Corporation of the aggregate Exercise Price, in accordance with Section
6(B) hereof and the Stock Option Agreement, for the shares of Incentive Stock to
be purchased pursuant to such exercise (as shall be specified by such
Participant in such notice). Except as specifically provided by a duly executed
Stock Option Agreement or unless waived by the Board of Directors, an Option or
any of the rights thereunder may be exercised by such Participant only, and may
not be transferred or assigned, voluntarily, involuntarily or by operation of
law (including, without limitation, the laws of bankruptcy, intestacy, descent
and distribution and succession).

            B.    Payment by each Participant for the shares of Incentive Stock
purchased hereunder upon the exercise of an Option shall be made by good check
or in accordance with the terms of any Stock Option Agreement executed by such
Participant.

            C.    The Board of Directors at any time or from time to time may
offer to buy out for a payment in cash or Incentive Stock all or a portion of an
outstanding Option held by a Participant, based on such terms and conditions as
the Board of Directors shall establish and communicate to the Participant at the
time that such offer is made. The Board of Directors may provide for the
surrender of all or any portion of an Option in satisfaction of specified
obligations of a Participant, including tax withholding obligations.

            D.    As a condition to the exercise of any Option or SAR (for
non-cash consideration), the Corporation shall have the right to require that
the Participant (or the recipient of any shares of Incentive Stock or noncash
consideration) remit to the Corporation or any Parent or Subsidiary an amount
calculated by the Corporation to be sufficient to satisfy applicable Federal,
state, foreign or local withholding tax requirements prior to the delivery of
any stock certificate evidencing shares of Incentive Stock or other form of
non-cash consideration; in lieu

                                       -5-
<PAGE>

thereof, the Participant may satisfy applicable withholding tax requirements by
electing to have the Corporation withhold from the Incentive Stock issuable upon
exercise of an Option a number of whole shares having a Fair Market Value
(determined on the date that the amount of tax to be withheld is to be fixed) at
least equal to the aggregate amount required to be withheld. Whenever any
payments are to be made in cash (upon the exercise of a SAR or otherwise), the
Corporation shall be entitled, in its sole discretion, to deduct from such
payment such amount calculated by the Corporation to be sufficient to satisfy
applicable Federal, state, foreign or local withholding tax requirements
thereon.

      7.    Costs and Expenses.

            All costs and expenses with respect to the adoption, implementation,
interpretation and administration of this Plan shall be borne by the
Corporation; provided, however, that, except as otherwise specifically provided
in this Plan or the applicable Stock Option Agreement between the Corporation
and a Participant, the Corporation shall not be obligated to pay any costs or
expenses (including legal fees) incurred by any Participant in connection with
any Stock Option Agreement, this Plan or any Option, SAR or Incentive Stock held
by any Participant.

      8.    No Prior Right of Award.

            Nothing in this Plan shall be deemed to give any director, officer
or employee of, or advisor or consultant to, the Corporation or any Parent or
Subsidiary, or such person's legal representatives or assigns, or any other
person or entity claiming under or through such person, any contract or other
right to participate in the benefits of this Plan. Nothing in this Plan shall be
construed as constituting a commitment, guarantee, agreement or understanding of
any kind or nature that the Corporation or any Parent or Subsidiary shall
continue to employ, retain or engage any individual (whether or not a
Participant). This Plan shall not affect in any way the right of the Corporation
and any Parent or Subsidiary to terminate the employment or engagement of any
individual (whether or not a Participant) at any time and for any reason
whatsoever and to remove any individual (whether or not a Participant) from any
position as a director or officer. No change of a Participant's duties as an
employee of the Corporation or any Parent or Subsidiary shall result in a
modification of the terms of any rights of such Participant under this Plan or
any Stock Option Agreement executed by such Participant.

      9.    Changes in Capital Structure.

            Subject to any required action by the stockholders of the
Corporation and the provisions of the DGCL, the number of shares of Incentive
Stock represented by the unexercised portion of an Option or SAR and the number
of shares of Incentive Stock which has been authorized or reserved for issuance
hereunder (whether such shares are unissued, reacquired or subject to an Option
or SAR that expired, was cancelled, surrendered or terminated unexercised as to
such shares), as well as the Exercise Price under the unexercised portion of an
Option or SAR, shall be proportionately adjusted for (a) a division, combination
or reclassification of any of the shares of Common Stock of the Corporation or
(b) a dividend payable in shares of Common Stock of the Corporation.

      10.   Amendment or Termination of Plan.

            Except as otherwise provided herein, this Plan may be amended or
terminated in whole or in part by the Board of Directors (in its sole
discretion), but no such action shall adversely affect or alter any right or
obligation with respect to any Option, SAR or Stock Option Agreement then in
effect, except to the extent that any such action shall be required or desirable
(in the opinion of the Corporation or its counsel) so that any Option intended
to qualify as an ISO complies with the Code or any rule or regulation
promulgated or proposed thereunder.

      11.   Burden and Benefit.

            The terms and provisions of this Plan shall be binding upon, and
shall inure to the benefit of, each Participant and such Participant's executors
and administrators, estate, heirs and personal and legal representatives.

      12.   Headings.

            The headings and other captions contained in this Plan are for
convenience and reference only and shall not be used in interpreting, construing
or enforcing any of the provisions of this Plan.

      13.   Interpretation.

            Notwithstanding any provision of this Plan or any provision of any
Stock Option Agreement evidencing an Option that is intended, in whole or in
part, to qualify as an ISO, this Plan and each such Stock Option Agreement are
intended to comply with all requirements for qualification under the Code and
with any rule or regulation promulgated or proposed thereunder, and shall be
interpreted and construed in a manner which is consistent with this Plan and
each such Stock Option Agreement being so qualified. This Plan shall be governed
by, and construed in accordance with, the substantive laws of the DGCL.

again be subject to an Option or SAR under this Plan. To the extent there shall
be any adjustment pursuant to the provisions of Section 9 hereof, the aforesaid
number of shares shall be appropriately so adjusted."

                    AMENDMENT NO. 4 TO THE STOCK OPTION PLAN

         This Amendment No. 4 to the Stock Option Plan ("Amendment No. 4") is
made and effective this 18th day of January 2005 by Vocus, Inc., a Delaware
corporation (the "Corporation").

         WHEREAS, the Corporation's board of directors (the "Board") and
stockholders previously adopted the Company's Stock Option Plan (the "Plan") on
September 24, 1999 and subsequently amended the Plan on January 11, 2000,
October 19, 2000 and June 13, 2001;

         WHEREAS, as presently in effect, 3,776,190 shares of the Corporation's
common stock, par value $.01 per share ("Common Stock"), are available for grant
under the Plan; and

         WHEREAS, the Board and the stockholders have approved a further
amendment to the Plan to increase the aggregate number of shares of Common Stock
available for award under the Plan from 3,776,190 shares to 5,276,190 shares.

         NOW, THEREFORE, the Plan is hereby amended by deleting Section 4 of the
Plan in its entirety and replacing it with the following:

         "4.      Total Number of Shares of Incentive Stock.

                  The number of shares of Incentive Stock which (a) may be
issued in the aggregate by the Corporation under this Plan pursuant to the
exercise of Options granted hereunder and (b) may be covered by SARs granted
hereunder which have not expired unexercised shall not be more than 5,276,190,
which number may be increased only by a resolution adopted by the Board of
Directors and approved within twelve (12) months after such adoption by the
stockholders of the Corporation in accordance with applicable state law. Such
shares of Incentive Stock may be issued out of the authorized and unissued or
reacquired Common Stock of the Corporation. Any shares subject to an Option, SAR
or portion thereof which expires or is terminated unexercised (unless by virtue
of the exercise of an Option or SAR granted in tandem therewith) as to such
shares may again be subject to an Option or SAR under this Plan. To the extent
there shall be any adjustment pursuant to the provisions of Section 9 hereof,
the aforesaid number of shares shall be appropriately so adjusted."

         IN WITNESS WHEREOF, the Corporation has caused this Amendment No. 4 to
be executed as of the date first written above.

VOCUS, INC.,
a Delaware corporation

By:_________________________________________     _______________________________

<PAGE>

                                   VOCUS, INC.
                             STOCK OPTION AGREEMENT

THIS STOCK OPTION AGREEMENT (this "Agreement") is made as of the Option Grant
Date set forth on the initial Notice of Stock Option Grant hereto by and between
(i) Vocus, Inc., a Delaware corporation (the "Corporation"), and (ii)
Participant, an employee of the Corporation or its Parent or Subsidiary as named
on each Notice of Stock Option Grant hereto.

WHEREAS, the Corporation has adopted the Vocus, Inc. 1999 Stock Incentive Plan
(the "Plan"), a copy of which has been previously provided to Participant; and

WHEREAS, the Board of Directors of the Corporation has determined that
Participant is eligible to receive an option to purchase shares of "Incentive
Stock," as such term is defined in the Plan.

NOW, THEREFORE, in consideration of the foregoing, of the mutual promises
hereinafter set forth and of other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties hereto, intending
to be legally bound, do hereby agree as follows:

1. Grant of Option. Subject to the terms and conditions hereinafter set forth,
the Corporation hereby grants to Participant the right to purchase, during the
period specified in Section 2 hereof, the number of shares of Incentive Stock
(such shares of Incentive Stock being hereinafter referred to as the "Shares")
set forth on each Notice of Stock Option Grant hereto at an exercise price of
per Share as set forth on each respective Notice of Stock Option Grant, in
accordance with the terms of this Agreement and the Plan (such right being
hereinafter referred to as the "Option").

2. Duration of Option.

      A. The Option shall be effective during the period commencing as of the
Option Grant Date and ending on the earliest to occur of: (i) the date all of
the Shares are purchased pursuant to the terms of this Agreement; (ii) the date
on which the Participant's employment is terminated by the Corporation for Cause
(as defined below) or the date as of which the Participant voluntarily
terminates from employment after an event that would be grounds to terminate the
Participant's employment for Cause; (iii) ninety (90) days after the date of the
termination of employment of Participant on any other grounds (except for death
or Permanent and Total Disability, as defined in Section 2.B below); (iv) the
expiration of the period prescribed under Section 2.B hereof in the event of
death or Permanent and Total Disability; and (v) the tenth (10th) anniversary of
the Option Grant Date. Upon the expiration of the Option, the Option shall have
no further force or effect, and Participant shall have no further rights in or
under the Option or to the Shares which shall not have been purchased by such
time pursuant to the Option. For purposes of this Agreement, if the Participant
is subject to an employment agreement with the Corporation as of the Option
Grant Date of a Stock Option that defines "Cause" or words of like import,
"Cause" shall have the meaning provided for in such employment agreement. If the
Participant is not subject to an employment agreement as of the Option Grant
Date that defines "Cause" or words of like import, "Cause" shall mean (i)
embezzlement, theft, fraud, or any other act of dishonesty involving the
Corporation or any of its customers, (ii) Participant's conviction of a felony,
or any other crime involving moral turpitude, or (iii) Participant's continued
failure substantially to perform the Participant's duties and responsibilities
to the Corporation that materially and adversely affects or threatens to affect
the business or reputation of the Corporation; provided, however, that the
Participant first will be provided with written notice of the Corporation's
intention to terminate the Participant's employment for Cause and the
Participant shall have thirty (30) days from the date of such notice to cure
such non-performance, if curable.

                                     - 2 -

<PAGE>

      B. In the event of the death of Participant at such time that Participant
shall possess an Option pursuant to the terms of this Agreement, Participant's
estate, executors or administrators, or personal or legal representatives shall,
subject to earlier termination as provided in the Plan and this Agreement, be
entitled, for a period of one (1) year following the date of Participant's
death, to exercise the Option, but only to the extent that Participant was
entitled to exercise the Option on the date of such death. Any person so
desiring to exercise Participant's Option shall be required, as a condition to
the exercise of the Option, to furnish to the Corporation such documentation as
the Corporation shall deem satisfactory to evidence the authority of such person
to exercise the Option on behalf of Participant. In the event the Participant
terminates from employment from the Corporation as a result of a permanent and
total disability (within the meaning of Section 22(e)(3) of the Code), the
Participant shall, subject to earlier termination as provided in the Plan and
this Agreement, be entitled for a period of one (1) year following the date of
Participant's termination of employment to exercise the Option, but only to the
extent the Participant was entitled to exercise the Options as of the date of
such termination of employment.

3. Exercise of Option.

      A. The Option may be exercised only to the extent vested on the date of
exercise and except as provided in the Notice of Stock Option Grant vesting of
the Option shall immediately cease upon termination of Participant's employment
with the Corporation. For purposes of this Agreement and the Notice of Stock
Option Grant, employment by the Parent, Subsidiary or other entity which is
directly or indirectly controlled fifty percent (50%) or more by the
Corporation, shall be treated as employment by the Corporation. The Board of
Directors shall determine whether employment shall be considered to have
terminated in the case of a leave of absence approved by the Corporation. The
Option may be exercised only if compliance with all applicable Federal and state
securities laws can be effected and only by (i) Participant's completion,
execution and delivery (by written or electronic means) to the Corporation of a
Notice and Request of Exercise in the form attached hereto or as otherwise
specified by the Corporation, and (ii) the payment to the Corporation, as
provided in Section 3.B hereof, of an amount equal to the amount obtained by
multiplying the Exercise Price by the number of Shares being purchased pursuant
to such exercise, as shall be specified by Participant in such notice of
exercise. Except in the event of the death of a Participant, in which event
Participant's estate, executors or administrators, or personal or legal
representatives may exercise the Option in accordance with the terms of Section
2.B hereof, the Option or any of the rights thereunder may be exercised by
Participant only, and may not be transferred or assigned, in whole or in part,
whether voluntarily, involuntarily or by operation of law (including, without
limitation, the laws of bankruptcy, intestacy, descent and distribution and
succession) or on an absolute or contingent basis.

      B. Payment of the amount determined pursuant to Section 3.A hereof shall
be made by: (i) cash; (ii) by good check; (iii) by delivery of shares of Common
Stock owned by Participant valued at their fair market value as determined by
the Board of Directors in good faith (which shares of Common Stock shall have
been owned by Participant at least six (6) months prior to such delivery); (iv)
if permitted by the Board of Directors, delivery by Participant of a full
recourse promissory note payable to the Corporation in the form approved by the
Board of Directors; (v) if permitted by the Board of Directors, by a
broker-assisted cashless exercise in accordance with Regulation T of the Board
of Governors of the Federal Reserve System through a brokerage firm approved by
the Board of Directors; or (vi) in such other manner as shall then be acceptable
to, and permitted by, the Board of Directors.

      C. Upon the exercise of the Option by Participant, or as soon thereafter
as is practicable, the Corporation shall issue and deliver to Participant a
certificate or certificates

                                     - 3 -

<PAGE>

evidencing such number of Shares as Participant has so elected to purchase. Such
certificate or certificates shall be registered in the name of Participant and,
if applicable, shall bear an appropriate investment warranty legend, any legend
required by any Federal or state securities law, rule or regulation and, if
applicable, a legend referring to the restrictions provided hereunder and under
the Plan and any legend required by the law of the jurisdiction of incorporation
of the Corporation. Upon the exercise of the Option and the issuance and
delivery of such certificate or certificates, Participant shall have all the
rights of a stockholder with respect to such Shares and to receive all dividends
or other distributions paid or made with respect thereto; provided, however,
that such Shares shall be subject to the restrictions (if any) hereunder and in
the Plan.

      D. Participant hereby agrees that if so requested by the Corporation or
any representative of the underwriters (the "Managing Underwriter") in
connection with any registration of the offering of any securities of the
Corporation under the Securities Act of 1933, as amended (the "Securities Act"),
Participant shall not, 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 Corporation) (the "Market Standoff Period") following the effective date of
a registration statement of the Corporation filed under the Securities Act,
offer, pledge, sell, contract to sell, sell any option or contract to purchase,
purchase any option or contract to sell, grant any option, right or warrant to
purchase, lend or otherwise transfer or dispose of any Shares or other
securities of the Corporation, or enter into any swap or other arrangement that
transfers to another, in whole or in part, any of the economic consequences of
ownership of the Shares or other securities of the Corporation, whether any such
previously described transaction is to be settled by delivery of the Shares or
other securities, in cash or otherwise; provided, however, that the foregoing
such restriction shall apply only to the first registration statement of the
Corporation to become effective under the Securities Act that includes
securities to be sold on behalf of the Corporation to the public in an
underwritten public offering under the Securities Act. Participant further
agrees that Participant shall execute any "lock-up letter" or similar instrument
submitted by the Managing Underwriter to Participant that reflects the foregoing
restrictions or any part thereof and that the Managing Underwriter shall be a
third party beneficiary of the provisions of this Section 3.D and shall be fully
entitled to enforce all rights set forth herein. Participant hereby irrevocably
appoints the Corporation and its President, or either of them, as Participant's
agents and attorneys-in-fact, with full power of substitution for and in
Participant's name, to execute any such "lock up letter" or similar instrument
submitted by the Managing Underwriter and to do any and all things in connection
therewith, it being understood and acknowledged by Participant that such power
of attorney shall not impose or be deemed to impose any fiduciary duty or any
other or obligation on either the Corporation or its President, shall be
irrevocable and coupled with an interest and shall not terminate by operation of
law, whether by the death, bankruptcy or adjudication of incompetency or
insanity of Participant or the occurrence of any other event. The Corporation
may impose stop-transfer instructions with respect to securities subject to the
foregoing restrictions until the end of such Market Standoff Period. Participant
further agrees that without the prior written consent of the Managing
Underwriter, Participant shall not, during the Market Standoff Period, make any
demand for or exercise any right (to the extent Participant shall have any such
right) with respect to, the registration of any Shares or other securities of
the Corporation.

4. Changes in Capital Structure of the Corporation. Subject to any required
action by the stockholders of the Corporation and the provisions of the
applicable law of the jurisdiction of incorporation of the Corporation, the
number of shares of Incentive Stock subject to this Agreement as well as the
Exercise Price of any Shares not yet purchased by Participant shall be
proportionately adjusted for (i) a division or combination of the shares of
capital stock of the Corporation, (ii) a dividend payable

                                     - 4 -

<PAGE>

in shares of capital stock of the Corporation or (iii) a reclassification of any
shares of capital stock of the Corporation. If the Corporation is merged or
consolidated with another entity or sells or otherwise disposes of substantially
all of its assets to another company while the Option remains outstanding under
the Plan, unless provisions are made in connection with such transaction for the
continuance of the Plan and/or the assumption or substitution of such Option
with new options or stock awards covering the stock of the successor company, or
Parent or Subsidiary thereof, with appropriate adjustments as to the number and
kind of shares and prices, then immediately prior to any such merger,
consolidation or sale, 50% of the unvested portion of the Option shall thereupon
vest and such portion shall thereupon become immediately exercisable. Upon
consummation of such merger, consolidation or sale all unexercised options shall
terminate.

5. Option of the Corporation to Purchase Shares Upon Termination of Employment.

      A. In the event that Participant shall have been issued Shares by the
Corporation pursuant to Participant's exercise of the Option, and in the further
event of the termination of employment of such Participant at any time and for
any reason whatsoever, the Corporation shall have the option (but shall not be
obligated) to purchase any or all of the Shares owned by Participant and
Participant's estate, executors or administrators, personal or legal
representatives, and permitted transferees (direct or indirect). For purposes of
this Section, any reference to Participant shall (when applicable) be deemed to
be and include references to Participant's estate, executors or administrators,
personal or legal representatives, and permitted transferees (direct or
indirect).

      B. The option specified in Section 5.A hereof, to the extent applicable,
may be exercised by the Corporation at any time after the termination of
employment of Participant, by the sending of written notice (in accordance with
the terms of this Agreement) of such exercise to Participant, specifying the
time and date on which payment to Participant of the purchase price, as
determined in accordance with Section 5.E hereof, of such Shares of Participant
to be purchased by the Corporation is to be made, and the number of Shares to be
so purchased by the Corporation. The date specified shall not be later than
sixty (60) days after the date such Registered Notice is sent. Settlement shall
be held on the purchase of Participant's Shares under this Section 5 at the
principal executive office of the Corporation or at such other place as the
Corporation and Participant shall otherwise agree. At settlement, Participant
shall deliver to the Corporation the certificate or certificates, duly endorsed,
evidencing all of Participant's Shares being purchased by the Corporation
pursuant to this Section 5 and, simultaneously therewith, the Corporation shall
deliver to Participant a good check in the amount of the purchase price of the
Shares being purchased by the Corporation.

      C. For purposes of this Section 5, (i) "termination of employment" shall
mean termination of employment with the Corporation for any reason whatsoever,
including, without limitation, death, Permanent and Total Disability,
retirement, voluntary termination, involuntary termination, dismissal with or
without Cause or resignation.

      D. In the event that Participant is unable to, or for any reason does not,
deliver to the Corporation such certificate or certificates, stock powers or
other instruments of transfer, duly endorsed and in accordance with the
provisions of this Section 5, the Corporation may, in its sole discretion,
deposit a check, or a check and promissory note (as the case may be), in the
total amount of the purchase price, as determined in accordance with Section 5.E
hereof, whichever is applicable, with any bank doing business within sixty (60)
miles of the Corporation's principal executive office, or with the accountant or
accountants then servicing the Corporation, as agent or trustee, or in escrow
for Participant, to be held by such bank or accountant or accountants until
withdrawn by Participant. Upon such deposit by the Corporation, Participant's
Shares shall at such time be deemed to have been sold, assigned, transferred and
conveyed to the Corporation, and

                                     - 5 -

<PAGE>

Participant shall have no further rights with respect thereto.

      E. The per share purchase price of the Shares to be purchased and sold
pursuant to this Section 5 shall be equal to the fair market value of each such
Share, as determined in good faith by the Board of Directors of the Corporation,
in its sole and absolute discretion.

6. Rights Prior to Exercise. Participant shall have no equity interest in the
Corporation or any voting, dividend, liquidation or dissolution rights with
respect to any capital stock of the Corporation solely by reason of having an
Option or having executed this Agreement. Furthermore, prior to the exercise of
all or a portion of the Option, as set forth in Section 3.A hereof, and the
issuance and delivery of a certificate or certificates evidencing the Shares
purchased pursuant to the exercise of all or a portion of such Option,
Participant shall have no interest in, or any voting, dividend, liquidation or
dissolution rights with respect to, the Shares, except to the extent that
Participant has exercised all or a portion of such Option and has been issued
and received delivery of a certificate or certificates evidencing the Shares
purchased pursuant to such exercise.

7. Treatment of Information.

      A. Participant acknowledges that, in and as a result of Participant's
employment by the Corporation, Participant shall or may be making use of,
acquiring and/or adding to confidential information of a special and unique
nature and value relating to such matters as the Corporation's trade secrets,
systems, programs, procedures, manuals, confidential reports and communications,

distributor, customer or strategic partner, and lists and/or electronic mail
addresses of customers and prospective customers. Participant further
acknowledges that any information and materials received by the Corporation from
third parties in confidence (or subject to nondisclosure or similar covenants)
shall be deemed to be and shall be confidential information within the meaning
of this Section 7. As a material inducement to the Corporation to grant to
Participant the Option, Participant covenants and agrees that Participant shall
not, except with the prior written consent of the Corporation, or except if
Participant is acting as an employee of the Corporation solely for the benefit
of the Corporation in connection with the Corporation's business and in
accordance with the Corporation's business practices and employee policies, at
any time during or following the term of Participant's employment by the
Corporation, directly or indirectly, disclose, divulge, reveal, report, publish,

been obtained by or disclosed to Participant as a result of Participant's
employment with the Corporation, including any of the information referred to in
Section 8 hereof.

      B. Disclosure of any such information of the Corporation shall not be
prohibited if such disclosure is directly related to a valid and existing order
of a court or other governmental body or agency within the United States;
provided, however, that (i) Participant shall first have given prompt notice to
the Corporation of any possible or prospective order (or proceeding pursuant to
which any such order may result) and (ii) the Corporation shall have been
afforded a reasonable opportunity to prevent or limit any such disclosure.

report, publish, transfer or use, for any purpose whatsoever, any Protected
Information, Participant shall bear the burden of proving that any such
information shall have become publicly available without any such breach.

Proprietary Information. Participant understands that, to the extent this
Agreement shall be construed in accordance with the laws of any state which
precludes a requirement in an employee agreement to assign certain classes of
inventions made by an employee, this Section 9 shall be interpreted not to apply
to any invention which a court of competent jurisdiction rules and/or the
Corporation agrees falls within such classes. Participant also hereby waives all
claims to moral rights in any Developments.

      C. Participant agrees to cooperate fully with the Corporation, both during
and after Participant's employment with the Corporation, with respect to the
procurement, maintenance and enforcement of copyrights, patents and other
intellectual property rights (both in the United States and foreign countries)
relating to Developments. Participant shall sign all papers, including, without
limitation, copyright applications, patent applications, declarations, oaths,
formal assignments, assignments of priority rights and powers of attorney, which
the Corporation may deem necessary or desirable in order to protect its rights
and interests in any Development. Participant further agrees that if the
Corporation is unable, after reasonable effort, to secure the signature of
Participant on any such papers, any executive officer of the Corporation shall
be entitled to execute any such papers as the agent and the attorney-in-fact of
Participant, and Participant hereby irrevocably designates and appoints each
executive officer of the Corporation as Participant's agent and attorney-in-fact
to execute any such papers on Participant's behalf, and to take any and all
actions as the Corporation may deem necessary or desirable in order to protect
its rights and interests in any Development, under the conditions described in
this sentence.

      D. Except to the extent previously disclosed to and acknowledged by the
Corporation in writing, there exist no inventions, improvements, discoveries,
methods, developments, software or works of authorship, whether patentable or
not, made, conceived, discovered or reduced to practice by Participant alone or
with others prior to Participant's employment by Corporation and/or its
predecessors ("Prior Developments"). Participant covenants and agrees that
Participant shall not include or use any intellectual property of Participant or
third parties (including, without limitation, Prior Developments) in
Developments without first notifying and receiving Corporation's written consent
to do so, and (ii) Participant hereby grants Corporation a perpetual,
royalty-free, worldwide, non-exclusive right and license to use, license,
distribute, create derivative works of and incorporate into Developments all
Prior Developments that Participant may from time to time include or incorporate
into Developments.

10. Covenants Not to Compete or Hire Employees. It is recognized and understood
by the parties hereto that the Corporation faces competition on a worldwide
basis and that Participant, through Participant's association with the
Corporation as an employee, shall acquire a considerable amount of knowledge and
goodwill with respect to the business of the Corporation, which knowledge and
goodwill are extremely valuable to the Corporation and which would be extremely
detrimental to the Corporation if used by Participant to compete with the
Corporation. It is, therefore, understood and agreed by the parties hereto that,
because of the nature of the business of the Corporation, it is necessary to
afford fair protection to the Corporation from such competition by Participant.
Consequently, as a material inducement to the Corporation to grant Participant
the Option, Participant covenants and agrees that for the period commencing with
the Option Grant Date and ending one (1) year after Participant's termination of
employment with the Corporation, except if Participant is acting as an employee
of the Corporation solely for the benefit of the Corporation in connection with
the Corporation's business and in accordance with the Corporation's business
practices and employee policies, (i) Participant shall not engage, directly,
indirectly or in concert with any other person or entity (including, without
limitation, those persons or entities in actual competition with the Corporation
such as Aristotle International, Inc., Bacon's Information, Inc., Biz360, Inc.,
BurrellesLuce, Cymfony, Inc., Democracy Data and

Communications, LLC, GetActive Software, Inc., Grassroots Enterprise, Inc.,
Legislative Demographic Services, Inc., Political Action Committee Services LLC,
Public Affairs Support Services, Inc., or TEKgroup International, Inc. or any
other company directly engaged in public relations or government relations
automation), in the business of public relations or government relations
automation, broadcast news monitoring or in the business of designing, selling,
developing, marketing, licensing, distributing or providing to others any
software, technology or services which perform functions which are the same or
similar to those performed by any software, technology or services being
designed, sold, developed, marketed, licensed, distributed or provided by the
Corporation, in each case as of the date of such termination of employment, and
(ii) Participant shall not collaborate with in any way whatsoever, or directly
or indirectly work for or with, any person or entity with which the Corporation
has any distribution, partnering, alliance or other similar agreement or
arrangement, whether as a proprietor, partner, co-venturer, financier, investor
or stockholder, director, officer, employer, employee, servant, agent,
representative or otherwise. Participant further covenants and agrees that for
the period commencing on the date of Participant's termination of employment
with the Corporation for any reason whatsoever and ending one (1) year after
Participant's termination of employment with the Corporation, Participant shall
not, directly or indirectly, (x) hire or engage or attempt to hire or engage any
individual who shall have been an employee of the Corporation at any time during
the two (2) year period prior to the date of Participant's termination of
employment with the Corporation, whether for or on behalf of Participant or for
any entity in which Participant shall have a direct or indirect interest (or any
subsidiary or affiliate of any such entity), whether as a proprietor, partner,
co-venturer, financier, investor or stockholder, director, officer, employer,
employee, servant, agent, representative or otherwise, or (y) induce or attempt
to induce any customer, developer, client, member, supplier, licensee, licensor,
franchisee or other business relation of the Corporation to cease doing business
with the Corporation, or in any way interfere with the relationship between any
such customer, developer, client, member, supplier, licensee or business
relation and the Corporation (including, without limitation, making any negative
statements or communications regarding the Corporation).

11. Materials. All notes, data, tapes, reference items, sketches, drawings,
memoranda, records and other materials in any way relating to any of the
information referred to in Sections 7 and 8 hereof (including, without
limitation, any Protected Information) or to the Corporation's business shall
belong exclusively to the Corporation and Participant agrees to turn over to the
Corporation all copies of such materials in Participant's possession or under
Participant's control at the request of the Corporation or, in the absence of
such a request, upon the termination of Participant's employment with the
Corporation.

12. Injunctive Relief. Participant understands and agrees that the Corporation
will suffer irreparable harm in the event that Participant breaches any of
Participant's obligations under Sections 7, 8, 9, 10, 11 or 16 hereof and that
monetary damages will be inadequate to compensate the Corporation for such
breach. Accordingly, Participant agrees that, in the event of a breach or
threatened breach by Participant of any of the provisions of such Sections, the
Corporation, in addition to and not in limitation of any other rights, remedies
or damages available to the Corporation at law or in equity, shall be entitled
to a temporary restraining order, preliminary injunction and permanent
injunction in order to prevent or to restrain any such breach by Participant, or
by any or all of Participant's partners, co-venturers, employers, employees,
servants, agents, representatives and any and all persons directly or indirectly
acting for, on behalf of or with Participant, and that the Corporation shall not
be required in connection with any such order or injunction to post a bond of
any nature whatsoever.

13. Accounting for Profits; Indemnification. Participant covenants and agrees
that, if

                                     - 9 -

<PAGE>

Participant shall violate any of Participant's covenants and agreements
contained in Sections 7, 8, 9, 10, 11 or 16 hereof, the Corporation shall be
entitled to an accounting and repayment of all profits, compensation, royalties,
commissions, remunerations or benefits which Participant directly or indirectly
shall have realized or may realize relating to, growing out of or in connection
with any such violation; such remedy shall be in addition to and not in
limitation of any injunctive relief or other rights or remedies to which the
Corporation is or may be entitled at law or in equity or otherwise under this
Agreement. Participant hereby agrees to defend, indemnify and hold harmless the
Corporation against and in respect of: (i) any and all losses and damages
resulting from, relating or incident to, or arising out of any misrepresentation
or breach by Participant of any warranty, covenant or agreement made or
contained in this Agreement; and (ii) any and all actions, suits, proceedings,
claims, demands, judgments, costs and expenses (including reasonable attorneys'
fees) incident to the foregoing.

14. Reasonableness of Restrictions. PARTICIPANT HAS CAREFULLY READ AND
CONSIDERED THE PROVISIONS OF SECTIONS 7 THROUGH 11 HEREOF INCLUSIVE AND SECTION
16 HEREOF AND, HAVING DONE SO, AGREES THAT THE RESTRICTIONS SET FORTH IN SUCH
SECTIONS ARE FAIR AND REASONABLE AND ARE REASONABLY REQUIRED FOR THE PROTECTION
OF THE INTERESTS OF THE CORPORATION, AND ITS OFFICERS, DIRECTORS, STOCKHOLDERS
AND EMPLOYEES.

15. Employment of Participant. Nothing in this Agreement shall be construed as
constituting a commitment, guarantee, agreement or understanding of any kind or
nature that the Corporation shall continue to employ Participant, nor shall this
Agreement affect in any way the right of the Corporation to terminate the
employment of Participant at any time and for any reason. By Participant's
execution of this Agreement and unless provided otherwise pursuant to the terms
of a written employment agreement, Participant acknowledges and agrees that
Participant's employment is "at will." No change of Participant's duties as an
employee of the Corporation shall result in, or be deemed to be, a modification
of any of the terms of this Agreement.

16. No Prior Agreements. Participant represents that Participant's performance
of all the terms of this Agreement and any services to be rendered as an
employee of the Corporation do not and shall not breach any fiduciary or other
duty or any covenant, agreement or understanding (including, without limitation,
any agreement relating to any proprietary information, knowledge or data
acquired by Participant in confidence, trust or otherwise prior to Participant's
employment by the Corporation) to which Participant is a party or by the terms
of which Participant may be bound. Participant covenants and agrees that
Participant shall not disclose to the Corporation, or induce the Corporation to
use, any such proprietary information, knowledge or data belonging to any
previous employer or others. Participant further covenants and agrees not to
enter into any agreement or understanding, either written or oral, in conflict
with the provisions of this Agreement. Participant further covenants and agrees
that the Corporation may send a copy of this Agreement and any other agreement
between Participant and the Corporation to any subsequent partner, co-venturer,
employer or agent of Participant and advise any such person of the substance of
this Agreement or any such other agreement (or any portion hereof or thereof).

17. Tax Matters. Notwithstanding that the Notice of Grant specifies that an
Option is intended to qualify as an "incentive stock option" under Section 422
of the Code, the Option will not qualify as an "incentive stock option," if any
of the following events occur: (i) the Participant disposes of the shares
acquired pursuant to the Option at any time during the two (2) year period
following the date of this Agreement or the one year period following the date
on which the Option is exercised; (ii) except in the event of the Participant's
death or

                                     - 10 -

<PAGE>

disability (as defined in Section 22(e)(3) of the Code), the Participant is not
employed by the Corporation, any Subsidiary or any Parent at all times during
the period beginning on the date of this Agreement and ending on the day three
(3) months before the date of exercise of the Option; or (iii) the aggregate
fair market value (determined as of the time the Option is granted) of the
shares subject to "incentive stock options" which become exercisable for the
first time in any calendar year exceeds $100,000. To the extent that the Option
does not qualify as an "incentive stock option", it shall not effect the
validity of the Option and shall constitute a separate nonqualified stock
option.

18. Burden and Benefit; Corporation. This Agreement shall be binding upon, and
shall inure to the benefit of, the Corporation and Participant, and their
respective heirs, personal and legal representatives, successors and assigns. As
used in Sections 2 and 4 through 10 hereof inclusive and this Section 18, the
term the "Corporation" shall also include any corporation or other entity which
is the parent or subsidiary of the Corporation. Participant hereby consents to
the enforcement of any and all of the provisions of this Agreement by or for the
benefit of the Corporation and any such other corporation.

19. Genders. The use of any gender herein shall be deemed to be or include the
other genders and the use of the singular herein shall be deemed to be or
include the plural (and vice versa), wherever appropriate.

20. Headings. The headings and other captions contained in this Agreement are
for convenience of reference only and shall not be used in interpreting,
construing or enforcing any of the provisions of this Agreement.

21. Entire Agreement. This Agreement sets forth all of the promises, agreements,
conditions, understandings, warranties and representations between the parties
hereto with respect to the subject matter of this Agreement, and there are no
promises, agreements, conditions, understandings, warranties or representations,
oral or written, express or implied, between them with respect to the Option or
the Shares other than as set forth herein. Any and all prior agreements between
the parties hereto with respect to the subject matter of this Agreement are
hereby revoked. This Agreement is, and is intended by the parties to be, an
integration of any and all prior agreements or understandings, oral or written,
with respect to the Option and the Shares. THE TERMS AND CONDITIONS OF THIS
AGREEMENT SHALL APPLY TO ANY FUTURE GRANTS OF INCENTIVE STOCK TO PARTICIPANT
PURSUANT TO THE PLAN AND THE TERM "OPTION GRANT DATE" SHALL REFER TO SUCH
SUBSEQUENT GRANT DATE. ANY SUCH FUTURE GRANTS AND ACCEPTANCE THEREOF SHALL BE
EVIDENCED BY THE COMPLETION, EXECUTION AND ATTACHMENT TO THIS AGREEMENT OF AN
ADDITIONAL NOTICE OF STOCK OPTION GRANT, IN THE FORM OF NOTICE OF STOCK OPTION
GRANT HERETO, OR AS OTHERWISE PROVIDED BY THE CORPORATION, WHICH SHALL BE
INCORPORATED HEREIN BY REFERENCE.

22. Notices. Any and all notices provided for herein shall be sufficient if in
writing, and sent by hand delivery or by certified or registered mail (return
receipt requested and first- class postage prepaid), in the case of the
Corporation, to its principal office, and, in the case of Participant, to
Participant's address as shown on the Corporation's records.

23. Invalid or Unenforceable Provisions. The provisions of this Agreement shall
be deemed severable, and the invalidity or unenforceability of any one or more
of the provisions hereof shall not affect the validity and enforceability of the
other provisions hereof. Participant agrees that the breach or alleged breach by
the Corporation of (i) any covenant contained in another agreement (if any)
between the Corporation and Participant or (ii) any obligation owed to
Participant by the Corporation, shall not affect the validity or enforceability
of the covenants and agreements of Participant set forth herein.

24. Governing Law. This Agreement shall be construed and enforced in accordance
with the substantive laws of the State of Delaware (other than provisions
thereof relating to conflicts-of-law or choice-of-law).

25. Modifications. No change or modification of this Agreement shall be valid
unless the same is in writing and signed by the parties hereto; provided,
however, that Participant hereby covenants and agrees to execute any amendment
to this Agreement which shall be required or desirable (in the opinion of the
Corporation or its counsel) in order to comply with any rule or regulation
promulgated or proposed under the Code by the Internal Revenue Service.

26. Terms and Conditions of the Plan. The terms and conditions included in the
Plan are incorporated by reference herein, and to the extent that any conflict
may exist between any term or provision of this Agreement and any term or
provision of the Plan, such term or provision of the Plan shall control.

Agreement.
