<PAGE>

     1.   Duties and Scope of Employment.
          ------------------------------

          (a)   Positions and Duties.  As of the Effective Date, Employee will
                --------------------
serve as Executive Vice President, Corporate Development, Mobile Telephony of
the Company.  Employee will render such business and professional services in
the performance of his duties, consistent with Employee's position within the
Company, as shall reasonably be assigned to him by the Company's Board of
Directors (the "Board").  The period of Employee's employment under this
Agreement is referred to herein as the "Employment Term."

          (b)   Obligations.  During the Employment Term, Employee will perform
                -----------
his duties faithfully and to the best of his ability and will devote his full
business efforts and time to the Company.  For the duration of the Employment
Term, Employee agrees not to actively engage in any other employment, occupation
or consulting activity for any direct or indirect remuneration without the prior
approval of the Board.

     2.   At-Will Employment.  The parties agree that the Employee's employment
          ------------------
with the Company will be "at-will" employment and may be terminated at any time
with or without cause or notice.  Employee understands and agrees that neither
his job performance nor promotions, commendations, bonuses or the like from the
Company give rise to or in any way serve as the basis for modification,
amendment, or extension, by implication or otherwise, of his employment with the
Company.

     3.   Compensation.
          ------------

          (a)   Base Salary. During the Employment Term, the Company will pay
                -----------
Employee as compensation for his services a base salary at the annualized rate
of not less than $204,750 (the "Base Salary").  The Base Salary will be
paid periodically in accordance with the Company's normal payroll practices and
be subject to the usual, required withholding.

          (b)   Bonus.  During the Employment Term, the Employee will be
                -----
eligible to participate in the Company's cash bonus program.

          (c)   Vesting of Spyglass Options.  On the Effective Date, twenty-five
                ---------------------------
percent (25%) of the unvested shares subject to Employee's Spyglass Options at
such time shall fully vest and become exercisable. The remaining shares subject
to the Spyglass Options shall vest and become exercisable in accordance with the
terms of the Spyglass Plan and the applicable Spyglass Options Agreement.

          (d)   Initial Stock Option Grant. On the first day of the calendar
                --------------------------
month immediately following the Effective Date (the "Grant Date"), the Company
shall grant to the Employee a stock option, which shall be an incentive stock
option under Section 422 of the Internal Revenue Code to the maximum extent
permitted thereby, (the "Company Option") to purchase that number of shares of
Company common stock equal to twenty-five percent (25%) of Employee's unvested
shares of Company common stock subject to the Spyglass Options, as determined
one day prior to the Effective Date(as adjusted for any stock splits, stock
dividends and similar events). The exercise price of the Company Option shall
equal the fair market value of the Company's common stock on the Grant Date.
Subject to the accelerated vesting provisions set forth herein, the Company
Option will vest as to 25% of the shares subject to the Company Option one year
after the Grant Date, and as to an additional 1/48th of the shares subject to
the Company Option monthly thereafter, so that the

                                      -2-
<PAGE>

Company Option will be fully vested and exercisable four (4) years from the
Grant Date, subject to Employee's continued service to the Company on the
relevant vesting dates. The Company Option will be subject to the terms,
definitions and provisions of the Company's Amended and Restated 1999 Share
Option/Share Issuance Plan (the "Option Plan") and the stock option agreement by
and between Employee and the Company, substantially in the form attached hereto
as Exhibit A (the "Option Agreement"), both of which documents are incorporated
herein by reference.

          (e)   Subsequent Stock Option Grant.  On the first anniversary of the
                -----------------------------
Grant Date, (the "Subsequent Grant Date"), the Company shall grant to the
Employee a stock option, which shall be an incentive stock option under Section
422 of the Internal Revenue Code to the maximum extent permitted thereby, (the
"Subsequent Option") to purchase that number of shares of Company common stock
equal to the product of (i) 25% of the Employee's unvested shares of Company
common stock subject to the Spyglass Options, as determined on the day prior to
the Effective Date (as adjusted for any stock splits, stock dividends and
similar events), multiplied by (ii) the quotient of (A) the number of Spyglass
employees who are employed by Spyglass or its affiliates on the Effective Date
and who continue to be employed by Spyglass (or an affiliate of Spyglass or the
Company) on the one year anniversary of the Effective Date, plus those Spyglass
employees who are employed by Spyglass on the Effective Date and who are
terminated by the Company other than for Misconduct (as defined below) on or
prior to such one year anniversary of the Effective Date, divided by (B) the
number of Spyglass employees who are employed by Spyglass or its affiliates on
the day prior to the Effective Date. The exercise price of the Subsequent Option
shall equal the fair market value of the Company's common stock on the
Subsequent Grant Date. Subject to the accelerated vesting provisions set forth
herein, the Subsequent Option will vest as to 25% of the shares subject to the
Subsequent Option on the Subsequent Grant Date, and as to 1/48th of the shares
subject to the Subsequent Option monthly thereafter, so that the Subsequent
Option will be fully vested and exercisable three (3) years from the Subsequent
Grant Date, subject to Executive's continued service to the Company on the
relevant vesting dates. The Subsequent Option will be subject to the terms,
definitions and provisions of the Option Plan and the Option Agreement, both of
which documents are incorporated herein by reference.

     4.   Employee Benefits.  During the Employment Term, Employee will be
          -----------------
entitled to participate in the employee benefit plans currently and hereafter
maintained by the Company of general applicability to other employees of the
Company.  The Company reserves the right to cancel or change the benefit plans
and programs it offers to its employees generally, including Employee, at any
time.

     5.   Severance Benefits.
          ------------------

          (a)   Involuntary Termination.  If Employee's employment with the
                -----------------------
Company terminates, within three (3) years following the Effective Date, as a
result of an Involuntary Termination (as defined below), and Employee signs and
does not revoke a release of claims with the Company (which is reasonably
acceptable to the Company), then, subject to Section 10, Employee shall be
entitled to receive:

                (i)  continuing payments of severance pay (less applicable
withholding taxes) at a rate equal to the highest rate in effect at any time
following the Effective Date, as then in effect, for a period of six (6) months
from the date of such termination;

                                      -3-
<PAGE>

               (ii)   the pro-rata target bonus that Employee was scheduled to
earn under the Company's cash bonus plan (less applicable withholding);

               (iii)  the same level of health (i.e., medical, vision and
dental) coverage and benefits as in effect for the Employee on the day
immediately preceding the day of the Employee's termination of employment;
provided, however, that (A) the Employee constitutes a qualified beneficiary, as
defined in Section 4980B(g)(1) of the Internal Revenue Code of 1986, as amended;
(the "Code") and (B) Employee elects continuation coverage pursuant to the
Consolidated Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"),
within the time period prescribed pursuant to COBRA. The Company shall continue
to provide Employee with health coverage, with the Employee paying no more in
premiums than a similarly situated active employee of Spyglass, until the
earlier of (A) the date Employee is no longer eligible to receive continuation
coverage pursuant to COBRA, or (B) six (6) months from the termination date;

               (iv)   the greater of (A) thirty-three and one-third percent
(33.33%) of the then unvested shares subject to the Spyglass Options or (B)
12.5% of the shares originally subject to the Spyglass Options shall immediately
vest and become exercisable; and

               (v)    twelve and a half percent (12.5%) of the shares originally
subject to the Company Option and the Subsequent Option (collectively, the
"Company Options") and twelve and a half percent (12.5%) of the shares
originally subject to the restricted stock awards from Spyglass to Employee (the
"Restricted Stock Awards") shall immediately vest and become exercisable.

          (b)  Other Termination.  If Employee's employment with the Company
               -----------------
terminates other than as a result of an Involuntary Termination, then (i) all
vesting of the Spyglass Options and Company Options will terminate immediately
(provided that such options shall remain exercisable, to the extent vested, for
a period of not less than thirty days after such termination) and all payments
of compensation by the Company to Employee hereunder will terminate immediately
(except as to amounts already earned), and (ii) Employee will only be eligible
for severance benefits in accordance with the Company's established policies as
then in effect.

     6.   Waiver.
          ------

            (a)  Vesting Acceleration. Except as otherwise provided herein and
                 --------------------
subject to the consummation of the Merger, Employee hereby waives and forfeits
any right to accelerated vesting and exercisability of the shares subject to the
Spyglass Options and Restricted Stock Awards that Employee may otherwise be
entitled to under the terms and conditions of the Spyglass Plan, the Spyglass
Restricted Stock Award Agreement or any other existing agreements Employee has
with Spyglass.

            (b)  Severance Payments.  Except as otherwise provided in this
                 ------------------
Agreement and subject to the consummation of the Merger, the Employee hereby
waives and forfeits any right to severance payments or other benefits that
Employee may otherwise be entitled to under any Spyglass plan or agreement,
including, without limitation, any payments made pursuant to the Senior
Management Retention Agreement.

                                      -4-
<PAGE>

          (c)  Spyglass Employment and Confidentiality Agreement. This Agreement
               -------------------------------------------------
shall supersede and replace the Spyglass Employment and Confidentiality
Agreement in its entirety, effective immediately prior to the consummation of
the Merger.

     7.   Definitions.
          -----------

          (a) Involuntary Termination.  For purposes of this Agreement,
              -----------------------
"Involuntary Termination" shall mean termination of Employee's employment by
reason of: (i) Employee's involuntary dismissal or discharge by the Company for
reasons other than for Misconduct, or (ii) Employee's voluntary resignation
following (A) a change in Employee's authority or position with the Company
which materially reduces Employee's level of responsibility; provided, however,
that Employee's position and duties as specified in Section 1(a) hereof shall
not constitute such a change in Employee's authority or position, (B) a
reduction in Employee's Base Salary by more than fifteen percent (15%), or (C) a
more than de minimis breach by the Company of any of the provisions of Section 3
          -- -------
hereof that is not cured by Spyglass or the Company within 30 days following
receipt by the Company's general counsel from Employee of  written notice
specifying the breach, or (D) a relocation of Employee's place of employment as
in effect on the date upon which this Agreement is entered into by more than
fifty (50) miles, provided and only if such change, reduction or relocation is
effected by the Company without the Employee's written consent.

          (b) Misconduct. For purposes of this Agreement, "Misconduct" shall
              ----------
mean (i) gross and willful failure to perform services, if such failure
materially injures the Company and has not been cured within 30 days after
Employee was given notice of such failure by the Company, (ii) material
dishonesty, if such dishonesty injures the Company in more than a de minimis
                                                                  -- -------
manner, (iii) fraud or embezzlement as determined by a court, or (iv) conviction
of, or plea of "guilty" or "no contest" to, a felony under the laws of the
United States or any state thereof.

     8.   280G Best Results.  Payments and benefits under this Agreement shall
          -----------------
be made without regard to whether the deductibility of such payments or benefits
(or any other payments or benefits to or for the Employee's benefit) would be
limited or precluded by Section 280G of the Code and without regard to whether
such payments or benefits (or any other payments or benefits) would subject the
Employee to the federal excise tax levied on certain "excise parachute payments"
under Section 4999 of the Code; provided, that if the total of all payments and
benefits to or for the Employee's benefit, after deduction of all federal taxes
(including the tax set forth in Section 4999 of the Code, if applicable) with
respect to such payments and benefits (the "total after-tax payments"), would be
increased by the limitation or elimination of any payment or benefit under this
Agreement, amounts payable and benefits receivable under this Agreement shall be
reduced to the extent, and only to the extent, necessary to maximize the total
after-tax payments.  The determination as to whether and to what extent payments
and/or benefits under this agreement are required to be reduced in accordance
with the preceding sentence shall be made by agreement between the Employee and
the independent public accounting firm of the Company (whose fees and expenses
shall be borne solely by the Company).  To the extent that any elimination or
reduction of payments or benefits is made in accordance with this Section 8, the
determination as to the order in which payments and benefits shall be eliminated
or reduced shall be made by the Employee.

     9.   Confidential Information.  Employee agrees to enter into the Company's
          -------------------------
standard Employee Proprietary Information and Inventions Agreement,
substantially in the form attached

                                      -5-
<PAGE>

hereto as Exhibit B, (the "Confidential Information Agreement") upon commencing
          ---------
employment hereunder.

     10.  Conditional Nature of Severance Payments.
          ----------------------------------------

          (a)  Noncompete. Employee hereby agrees that: (i) the covenant set
               ----------
forth in this Section 10 is reasonable in scope and essential to the
preservation of the Company's (including any parent or subsidiary of the
Company) business; and (ii) the enforcement of such covenant will not preclude
Employee from being gainfully employed in such manner and to the extent
necessary to provide a standard of living for himself, the members of his family
and others dependent upon him. Employee further acknowledges that the nature of
the Company's (including any parent or subsidiary of the Company) business is
such that if Employee were to become employed by, or substantially involved in,
the business of a competitor of the Company (including any parent or subsidiary
of the Company) during the period ending on the later of (i) thirty-six (36)
months following the Effective Date, and (ii) one (1) year after the Employee's
termination date, it would be very difficult for the Employee not to rely on or
use the Company's (including any parent or subsidiary of the Company) trade
secrets and confidential information. Thus, to avoid the inevitable disclosure
of the Company's (including any parent or subsidiary of the Company) trade
secrets and confidential information and to protect the Company's (including any
parent or subsidiary of the Company) business, Employee agrees and acknowledges
that Employee's right to receive the severance payments and benefits set forth
in Section 5 (to the extent Employee is otherwise entitled to such payments and
benefits) shall be conditioned upon the Employee not directly or indirectly
engaging in (whether as an employee, consultant, agent, proprietor, principal,
partner, stockholder, corporate officer, director, advisor or otherwise), nor
having any ownership interest in or participating in the financing, operation,
management or control of, any person, firm, corporation or business that
competes with the business of the Company (including any parent or subsidiary of
the Company), as determined on the date of Employee's termination of employment;
provided that nothing contained in this Agreement shall prevent the Employee
from owning less than five percent of the outstanding capital stock of a
publicly-traded corporation. Upon any breach of this section and if such breach
has not been cured within 30 days after Employee was given notice of such breach
by the Company, all severance payments and other benefits pursuant to this
Agreement shall immediately cease.

          (b)  Non-Solicitation.  Until the date following the later of (i)
               ----------------
thirty-six (36) months following the Effective Date, or (ii) one (1) year after
the Employee's termination date, Employee agrees and acknowledges that
Employee's right to receive the severance payments and benefits set forth in
Section 5 (to the extent Employee is otherwise entitled to such payments and
benefits) shall be conditioned upon Employee not, either directly or indirectly,
soliciting, inducing, attempting to hire, recruiting, encouraging, taking away,
hiring any individual who is an employee of the Company (including any parent or
subsidiary of the Company) as of such termination date or causing an employee of
the Company or its affiliates to leave his or her employment either for Employee
or for any other entity or person.

          (c)  Understanding of Covenants.  The Employee represents that he (i)
               --------------------------
is familiar with the foregoing covenants not to compete and not to solicit, and
(ii) is fully aware of his obligations hereunder, including, without limitation,
the reasonableness of the length of time, scope and geographic coverage of these
covenants.

                                      -6-
<PAGE>

     11.  Assignment.  This Agreement will be binding upon and inure to the
          ----------
benefit of (a) the heirs, executors and legal representatives of Employee upon
Employee's death and (b) any successor of the Company.  Any such successor of
the Company will be deemed substituted for the Company under the terms of this
Agreement for all purposes.  For this purpose, "successor" means any person,
firm, corporation or other business entity which at any time, whether by
purchase, merger or otherwise, directly or indirectly acquires all or
substantially all of the assets or business of the Company.  None of the rights
of Employee to receive any form of compensation payable pursuant to this
Agreement may be assigned or transferred except by will or the laws of descent
and distribution.  Any other attempted assignment, transfer, conveyance or other
disposition of Employee's right to compensation or other benefits will be null
and void.

     12.  Notices.  All notices, requests, demands and other communications
          -------
called for hereunder shall be in writing and shall be deemed given (i) on the
date of delivery if delivered personally, (ii) one (1) day after being sent by a
well established commercial overnight service, or (iii) four (4) days after
being mailed by registered or certified mail, return receipt requested, prepaid
and addressed to the parties or their successors at the following addresses, or
at such other addresses as the parties may later designate in writing:

          If to the Company:


          OpenTV, Inc.
          401 East Middlefield Road
          Mountain View, California 94043-4005
          Attn: General Counsel
          ----

          If to Employee:

          at the last residential address known by the Company.

     13.  Severability.  In the event that any provision hereof becomes or is
          ------------
declared by a court of competent jurisdiction to be illegal, unenforceable or
void, this Agreement will continue in full force and effect without said
provision.

     14.  Arbitration.
          -----------

          (a)  Employee agrees that any dispute or controversy arising out of,
relating to, or in connection with this Agreement, or the interpretation,
validity, construction, performance, breach, or termination thereof, shall be
settled by binding arbitration to be held in Chicago, Illinois in accordance
with the National Rules for the Resolution of Employment Disputes then in effect
of the American Arbitration Association (the "Rules"). The arbitrator may grant
injunctions or other relief in such dispute or controversy. The decision of the
arbitrator will be final, conclusive and binding on the parties to the
arbitration. Judgment may be entered on the arbitrator's decision in any court
having jurisdiction.

          (b)  The arbitrator(s) will apply Illinois law to the merits of any
dispute or claim, without reference to rules of conflicts of law.  The
arbitration proceedings will be governed by federal arbitration law and by the
Rules, without reference to state arbitration law.  The Employee hereby consents
to the personal jurisdiction of the state and federal courts located in Illinois
for any

                                      -7-
<PAGE>

action or proceeding arising from or relating to this Agreement or relating to
any arbitration in which the parties are participants.

          (c)  EMPLOYEE HAS READ AND UNDERSTANDS THIS SECTION, WHICH DISCUSSES
ARBITRATION.  EMPLOYEE UNDERSTANDS THAT BY SIGNING THIS AGREEMENT, EMPLOYEE
AGREES TO SUBMIT ANY CLAIMS ARISING OUT OF, RELATING TO, OR IN CONNECTION WITH
THIS AGREEMENT, OR THE INTERPRETATION, VALIDITY, CONSTRUCTION, PERFORMANCE,
BREACH OR TERMINATION THEREOF TO BINDING ARBITRATION, AND THAT THIS ARBITRATION
CLAUSE CONSTITUTES A WAIVER OF EMPLOYEE'S RIGHT TO A JURY TRIAL AND RELATES TO
THE RESOLUTION OF ALL DISPUTES RELATING TO ALL ASPECTS OF THE EMPLOYER/EMPLOYEE
RELATIONSHIP, INCLUDING BUT NOT LIMITED TO, DISCRIMINATION CLAIMS.

     15.  Integration.  This Agreement, together with the Option Plan, Option
          -----------
Agreement, the Spyglass Options and the Confidential Information Agreement
represents the entire agreement and understanding between the parties as to the
subject matter herein and supersedes all prior or contemporaneous agreements
whether written or oral (other than obligations accrued under Spyglass' bonus
programs as of the Effective Date). No waiver, alteration, or modification of
any of the provisions of this Agreement will be binding unless in writing and
signed by duly authorized representatives of the parties hereto.

     16.  Tax Withholding.  All payments made pursuant to this Agreement will be
          ---------------
subject to withholding of applicable taxes.

     17.  Governing Law.  This Agreement will be governed by the laws of the
          -------------
State of Illinois (with the exception of its conflict of laws provisions).

     18.  Acknowledgment.  Employee acknowledges that he has had the opportunity
          --------------
to discuss this matter with and obtain advice from his private attorney, has had
sufficient time to, and has carefully read and fully understands all the
provisions of this Agreement, and is knowingly and voluntarily entering into
this Agreement.

                                      -8-

     IN WITNESS WHEREOF, each of the parties has executed this Agreement, in the
