        2.     Compensation and Benefits.

               2.1 Basic Salary. Employer shall pay a basic salary to Employee
at the rate of $220,000.00 per year, payable in equal bi-weekly installments in
accordance with Employer's regular payroll practices except as otherwise agreed
in writing between Employer and Employee, provided that no salary shall be due
or payable during any period of unpaid leave, in accordance with Employer's
regular policies as they may exist or be changed from time to time. The
compensation package shall be subject to periodic review, and any modifications
thereto must be in writing signed by the parties to this Agreement.

               2.2 Stock Options. On December 6, 1996, the Company granted to
Employee a nonstatutory option to purchase 150,000 shares of CKS Common Stock,
which option is evidenced by the stock option agreement attached hereto as
Exhibit A (the "Option Agreement"). In subsequent years (for example, the year
ending in May 1998), depending upon Employee's performance as evaluated by the
Employer and subject to applicable legal requirements, the Company may grant to
the Employee additional options in a manner consistent with the Employee's
status within the Company and the Company's treatment of other executives.

               2.3 Bonus. Employee shall be eligible for bonus compensation as
follows:

                      2.3.1 Personal Bonus. Employee shall be eligible for an
annual personal bonus of up to 50% of his basic salary, in addition to any
amounts that may be payable to Employee under Section 2.3.2 below, which annual
personal bonus shall depend upon (a) his performance and (b) the availability of
funds for the payment of such a bonus, as determined by the Board. The CEO shall
evaluate the Employee's performance no later than January 31, 1998 and annually
thereafter.

                      2.3.1.1 Determination of Amount of Personal Bonus. Within
90 days following the commencement of the Employee's employment with the
Company, Employee and the CEO will make a good faith effort to define objective
criteria by which Employee's performance shall be evaluated for purposes of
determining Employee's eligibility for a personal bonus. If the Employee and the
Company are able to define such criteria, the Employee's personal bonus, if any,
shall be calculated pursuant to those criteria. Employee and the Company
acknowledge that definition of such criteria may prove to be impractical,
however, in which case the evaluation of Employee's performance and the
determination of the amount of personal bonus, if any, to be paid the Employee
hereunder shall be at the sole discretion of the CEO and the Board.

                      2.3.2 Executive Compensation Plan. Employee shall be
eligible to participate in the 1997 Executive Compensation Plan (and similar
executive compensation plans adopted in subsequent years) in accordance with the
terms and conditions of such plans.

                      2.4.1.1 Effect of disability upon fringe benefits. If
Employee becomes disabled and unable to perform his duties and the Company's
disability insurance policy does not include provisions entitling Employee and
Employee's dependents to continued coverage under the Company's medical and
dental plans (at no cost to Employee or Employee's dependents) for so long as
such disability continues, then the Company shall continue to include Employee
and Employee's dependents on the Company's medical and dental insurance plans
(as they may exist from time to time) at the Company's expense for so long as
such disability continues.

                      2.4.2 Automobile. During the term of this Agreement,
Employer will provide Employee a monthly automobile allowance for the
acquisition, insurance and maintenance of a vehicle for CKS business use in an
amount equal to the greater of (a) $700 per month or (b) the amount provided to
Chief Financial Officer of the Company.

                      2.4.3 Vacation And Holidays. Employee shall be entitled to
annual vacation which will accrue at the rate of fifteen (15) working days per
year or such greater amount as is consistent with Employer's executive vacation
practices, subject, however, to the accrual maximums now or hereafter described
in Employer's policies for the accrual of unused vacation, but in no event shall
the accrual maximum for Employee be less than fifteen (15) working days per
year. Employee shall also be entitled to holiday pay for all holidays recognized
by Employer in accordance with the Employer's regular practices.

               2.5 Business Expenses. During Employee's employment, Employer
shall reimburse Employee for reasonable out-of-pocket expenses incurred in
connection with Employer's business, including travel and entertainment
expenses, food and lodging while away from home and cellular telephone expenses,
subject to such policies as Employer may from time to time establish for its
employees.

               2.6 Withholding. All amounts to be paid by CKS to the Employee
are subject to applicable withholding for taxes, if any. Employer may withhold
from any and all payments, compensation or other remuneration paid to Employee
such amounts as Employer believes it is required to withhold under any federal,
state, local or foreign law, rule or regulation.

               2.7 California Bar Association. For so long as Employee continues
to be employed by the Company, the Company will pay all dues and other fees
required for Employee to remain a member in good standing of the California Bar
Association and will also reimburse Employee for expenses incurred in completing
the minimum amount of continuing legal education to enable Employee to remain in
good standing of the California Bar Association.

space and location) available to the Employee immediately prior to such
reduction;

                         (c) a reduction by the Company of the Employee's base
salary or bonuses paid in comparison with the prior year;

                         (d) a material reduction by the Company in the kind or
level of employee benefits to which the Employee is entitled, with the result
that the Employee's overall benefits package is significantly reduced;

                         (e) any reduction, after a Change of Control, in the
disability benefits available to Employee prior to the Change of Control;

                         (f) the relocation of the Employee to a facility or a
location more than twenty (20) miles from his current location without the
Employee's express written consent, or

                         (g) the failure of the Company to obtain the assumption
of this Agreement by any successors contemplated in Section 6.10 below;

                         (h) an increase of 10% or more in the number of days
which the Employee travels outside of Santa Clara, San Mateo, San Francisco,
Santa Cruz, Contra Costa or Alameda Counties, in comparison with the number of
such days in the 12 months preceding the Change of Control (or, if Employee has
not been employed for 12 months at the time of the Change of Control, the number
of days determined by dividing the days Employee did travel by the number of
days Employee was employed, and multiplying the result by 365);

               provided that, with respect to subparagraphs (b), (d) and (e)
above, (i) the Employee notifies the Company of the facts allegedly constituting
his Constructive Termination and his intention to terminate his employment
within 30 days after he acquires knowledge of such facts, (ii) the Employee
affords the Company 30 days within which to remedy the alleged Constructive
Termination and (iii) the Company fails to remedy the alleged Constructive
Termination within such 30 days.

                      3.5.2 "Change of Control." As used in section 3.5 and its
subparts, "Change of Control" shall mean:

                         (a) the approval by shareholders of the Company of 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 the approval by
the shareholders of the Company of a plan of complete liquidation of the Company
or an agreement for the sale or disposition by the Company of all or
substantially all of the Company's assets.

                         (b) Any "person" (as such term is used in Sections
13(d) and 14(d) of the Securities Exchange Act of 1934, as amended, but
excluding officers of CKS and the Director of the Interpublic Group) becoming
the "beneficial owner" (as defined in Rule 13d-3 under said Act), directly or
indirectly, of securities of the Company representing 50% or more of the total
voting power represented by the Company's then outstanding voting securities;

                         (c) A change in the composition of the Board of
Directors of the Company occurring within a two-year period, as a result of
which fewer than a majority of the directors are Incumbent directors. "Incumbent
Directors" shall mean directors who either (i) are directors of the Company as
of the date hereof, or (ii) are appointed, 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
in connection with an actual or threatened proxy contest relating to the
election of directors of the Company.

                         3.5.3 Acceleration of Vesting Following Change of
Control. On the effectiveness of any Change of Control, the vesting of all
options granted to Employee by the Company shall be accelerated so that, as to
each such option, one half of the shares subject to such option which were not
otherwise vested at the effective time of the Change of Control shall become
vested at such effective time, and the remaining unvested shares shall continue
to vest thereafter at the same rate (number of shares per month) as was in
effect prior to the Change of Control.

                         3.5.4 Compensation due to Employee Upon Involuntary or
Constructive Termination Following a Change in Control. If, following a Change
of Control as defined above, the Employee's employment is terminated
involuntarily (for any reason) or by Constructive Termination, the Employer
shall

                          (i)  pay to Employee in a single lump sum an amount
                               equal to (A) 12 months basic salary (at the rate
                               in effect prior to the Change of Control or the
                               date of termination, whichever is greater), plus
                               (B) the total amount paid to or earned by
                               Employee as incentive compensation or bonus
                               payments during the twelve months preceding the
                               Change of Control or date of termination,
                               whichever is greater,

                         (ii)  reimburse Employee for the cost of continuing
                               Employee's (and Employee's dependents') medical,
                               disability, dental, life and similar benefits for
                               12 months pursuant to the Consolidated Omnibus
                               Budget Reconciliation Act ("COBRA"), if the
                               Employee elects to continue such benefits at the
                               time of his termination;

                        (iii)  continue for a period of twelve months to provide
                               the car allowance, professional association dues
                               and continuing legal education benefits enjoyed
                               by Employee immediately prior to the Change of
                               Control, and

                         (iv)  accelerate the vesting of all then unvested
                               options held by the Employee at the date of
                               termination such that those shares shall vest
                               immediately and Employee shall have two years
                               following the date of such termination in which
                               to exercise all options held by Employee at the
                               date of such termination;

provided that the Employee executes a Severance and General Release Agreement in
the form attached hereto as Exhibit B. In the event a Change of Control occurs
before Employee has been employed for twelve (12) months, Employee shall for
purposes of clause (i) above be deemed to have earned the maximum bonus for
which he is eligible during the twelve (12) months preceding Change in Control.

                      3.5.5 Effect of Employee's subsequent employment. Employee
shall have no obligation to mitigate damages or payments due under this
paragraph, nor shall any amounts earned by Employee be offset against the
amounts payable to Employee under Section 3.5 and its subsections.

               3.6 Termination By Death or Permanent Disability.

                      3.6.1 Definition of "Permanent Disability." For the
purpose of section 3.7 and its subparts, the term "Permanent Disability" means
the Employee's inability to perform his duties hereunder (with or without
reasonable accommodation) for 120 or more working days during any twelve-month
period.

                      3.6.2 Effect of Death or Permanent Disability of Employee.
The Employee's employment will terminate automatically upon the death or
Permanent Disability of Employee, in which case Employee or his estate will be
entitled only to compensation earned through the date of such death or Permanent
Disability; provided, however, that, in the event of a Permanent Disability,
Employer will continue to include Employee and Employee's dependents on the
Company's medical and dental insurance plans (as they may exist from time to
time) for so long as such disability continues at the Company's expense.

                      3.7 Effect of Dispute Regarding Nature of Termination. In
the event that the parties disagree on the nature of the termination of the
Employee's employment (such as whether a termination was for cause or not) and
submit such dispute to arbitration, the effective date of the termination of the
Employee's employment shall be determined as if no dispute arose. In the event
that the parties disagree on whether a Constructive Termination or Change in
Control has occurred and submit such dispute to arbitration, the Employee shall
be deemed to have terminated his employment without cause in the event if the
arbitrator determines that a Constructive Termination or Change in Control did
not occur.

               4. Trade Secrets and Confidential Information.

                      4.1 Proprietary Information. Employee recognizes that as
an executive of the Employer, Employee occupies a position of trust with respect
to much business information of a secret or confidential nature which is the
property of the Employer and which will be imparted to Employee from time to
time in the course of Employee's duties. Employee therefore agrees that Employee
shall not, at any time, whether in the course of his employment or thereafter,
use or disclose directly or indirectly to any person outside the Employer any of
such information, except as required in the ordinary course of Employee's duties
under this Agreement. Concurrently with the execution of this Agreement,
Employee shall sign the Proprietary Information Agreement attached hereto as
Exhibit C (the "Proprietary Information Agreement").

               4.2 Non-Competition with Employer. During his employment, and so
long as this contract remains in effect and any payments or benefits are
provided to the Employee, the Employee shall not, directly or indirectly,
promote, participate, or engage in any activity or other business



                                      -11-

<PAGE>   12

competitive with Employer's business, or any of its affiliates, and shall not
solicit the Company's employees or customers, or the employees or customers of
any of Employer's affiliates, nor shall Employee engage in any act or conduct
which creates, or appears to create, a conflict of interest with Employer,
except as may be approved in writing by the CEO; provided, however, that this
section 4.2 shall not apply if Employee is terminated involuntarily or by
constructive termination following a Change of Control.

        5.     Miscellaneous.

               5.1 Notice. All notices, requests and other communications
required or permitted to be given hereunder shall be in writing and shall be
deemed given (a) upon receipt, if given by personal delivery; (b) upon delivery,
if given by electronic facsimile, with proof of receipt; and (c) upon the third
business day following mailing, if mailed by deposit in the United States mail,
with certification and postal charges prepaid, addressed as follows (or such
other address as either party may provide to the other from time to time).

               5.2 Delegation of Duties. Employee may not delegate the services
and obligations he is required to perform under this Agreement. Any attempt by
Employee to delegate his duties hereunder shall be null and void.

               5.3 Amendment. This Agreement may be modified or amended only by
and to the extent of the written agreement of Employer and Employee.

               5.4 Previous Agreements. This Agreement, together with the
Proprietary Information Agreement and the Stock Option Agreement, contains the
entire agreement between the parties and supersedes all prior oral and written
agreements, understandings, commitments, and practices between the parties,
including all prior employment or consulting agreements, whether or not fully
performed before the date of this Agreement.

               5.5 Governing Law. Except as provided by section 5.8 below, this
Agreement shall be governed by and construed in accordance with the internal
laws of the State of California.

               5.6 Section Headings. The various section headings are inserted
for convenience of reference only and shall not affect the meaning or
interpretation of this Agreement or any section thereof.

               5.7 Severability. If provision of this Agreement is held by a
court of competent jurisdiction to be invalid, illegal or unenforceable, such
provision will be deemed amended to the minimum extent necessary to conform to
applicable law so as to be valid, legal and enforceable; if such provision
cannot be amended as provided above, it will be stricken and the remainder of
this Agreement will remain in full force and effect.

               5.8 Arbitration. It is further understood and agreed that if, at
any time, a violation of any term of this Agreement is asserted by any party
hereto, that party shall have the right to seek specific performance of that
term and/or any other necessary and proper relief, including but not limited to
damages, before an arbitrator as set forth below. Each party will pay its own
costs and attorneys fees. The Company shall pay the costs of the arbitrators.
The parties agree that if they have any dispute as to the terms of or
obligations created by this Agreement, or should either party to this Agreement
have any dispute as to Employee's termination or compensation, or should
Employee allege that Employer or any of its employees, managers, officers,
directors or other representatives has violated any of Employee's rights under
state or federal civil rights laws including, but not limited to, the California
Fair Employment and Housing Act (Cal. Gov. Code Sections 12900, et seq.), the
Civil Rights Act of 1964 (42 U.S.C. Sections 2000e, et seq.), the Equal Pay Act
of 1963 (29 U.S.C. Sections 206(d)), the Americans With Disabilities Act of 1990
(42 U.S.C. Sections 12101, et seq., or California Labor Code Section 1102.1,
they will submit any such dispute to final and binding arbitration before a
neutral arbitrator selected from the roster of Judicial Arbitration and
Mediation Services, or before any other neutral, and pursuant to any other such
procedures, as the parties may agree upon. To be timely, any such dispute must
be referred to arbitration within twelve (12) months of the incident or
complaint giving rise to the dispute; disputes not referred to arbitration
within such twelve (12) twelve month period shall be deemed waived, and the
arbitrator shall deny any untimely claims. THE PARTIES EXPRESSLY AGREE THAT SUCH
ARBITRATION SHALL BE THE EXCLUSIVE, FINAL AND BINDING REMEDY FOR ANY DISPUTE
INVOLVING OR RELATED TO AN ALLEGED BREACH OF THIS AGREEMENT, EMPLOYMENT
TERMINATION, COMPENSATION, THE VIOLATION OF MR. CLARKSON'S CIVIL RIGHTS, OR ANY
OTHER MATTER ARISING OUT OF OR RELATED TO MR. CLARKSON'S EMPLOYMENT, AND HEREBY
EXPRESSLY WAIVE ANY RIGHT THEY HAVE OR MAY HAVE TO A COURT TRIAL OR A JURY TRIAL
OF ANY SUCH DISPUTE. In making an award, the arbitrator shall have no power to
add to, delete from or modify this Agreement, or to enforce purported unwritten
agreements or prior agreements, or to construe implied terms or covenants into
the Agreement, the parties being in agreement that no such oral or implied terms
or covenants or unwritten agreements or prior agreements are intended by them to
remain enforceable, to the extent they may ever have been so. In reaching his or
her decision, the arbitrator shall adhere to the relevant law and applicable
precedent and shall have no power to vary therefrom. In



                                      -13-

<PAGE>   14

construing this Agreement, its language shall be given a fair and reasonable
construction in accordance with the intention of the parties, and without regard
to, or the aid of, Section 1654 of the California Civil Code. At the time of
issuing a decision, the arbitrator shall (in the decision or separately) make
specific findings of fact and shall set forth such facts as support the
decision, as well as his conclusions of law, and the reasons and bases for his
opinion, and such a decision incorporating these elements shall be a condition
precedent to its enforcement. The decision of the arbitrator shall be final and
binding; provided, however, that in the event the arbitrator exceeds the powers
or jurisdiction here conferred, or fails to issue a decision in conformance
herewith, it is specifically agreed that the aggrieved party may petition a
court of competent jurisdiction to correct or vacate such award, and that the
arbitrator's act of exceeding his or her powers shall be grounds for granting
such relief. It is further agreed by the parties that venue for any arbitration
proceedings shall be Santa Clara County, California. This arbitration clause is
entered pursuant to, and shall be governed by, the Federal Arbitration Act (9
U.S.C. Section  1, et seq.), but in all other respects this agreement shall be
governed by the provisions of California law. If any one or more provisions of
this arbitration clause shall for any reason be held invalid or unenforceable,
it is the specific intent of the parties that such provisions shall be modified
to the minimum extent necessary to make it or its application valid and
enforceable.

               5.9 Waiver. Waiver of any default or breach of this Agreement or
of any warranty, representation, covenant or obligation contained herein shall
not be construed as a waiver of any subsequent breach.

               5.10   Successors.

                      (a) Company's Successors. Any successor of the Company
(whether direct or indirect and whether by purchase, lease, merger,
consolidation, liquidation or otherwise) to all or substantially all of the
Company's business and/or assets shall assume the Company's obligations under
this Agreement and agree expressly to perform the Company's obligations under
this Agreement in the same manner and to the same extent as the Company would be
required to perform such obligations in the absence of a succession. For all
purposes under this Agreement, the term "Company" shall include any successor to
the Company's business and/or assets which executes and delivers the assumption
agreement described in this subsection (a) or which becomes bound by the terms
of this Agreement by operation of law.

                      (b) Employee's Successors. Except as otherwise provided in
this Agreement, the terms of this Agreement and all rights of the Employee
hereunder shall inure to the benefit of, and be enforceable by, the Employee's
personal or legal representatives, executors, administrators, successors, heirs,
distributees, devisees and legatees.

               5.11 Notice of Termination. Any termination of this Agreement by
the Company for cause or by the Employee with cause or without cause or
following a Change in Control or Constructive Termination shall be communicated
by a notice of termination to the other party hereto given in accordance with
this Section 5.11. Such notice shall indicate the specific termination provision
in this Agreement relied upon, shall set forth in reasonable detail the facts
and



                                      -14-

<PAGE>   15

circumstances claimed to provide a basis for termination under the provision so
indicated, and shall specify an effective date of termination which shall be no
more than 30 days after the giving of such notice.

        IN WITNESS WHEREOF, the parties have executed this Agreement in one or
more counterparts which, taken together, shall constitute one agreement.
