prerecorded or otherwise, of the programming of SBS's Stations commercials,
data, copy, written and recorded materials, as well as all recordings,

Extension Term, including without limitation the Employee's work product, are
the exclusive property of SBS ("Property Rights"), SBS owns or shall own all
right, title and interest throughout the Universe in and to Employee's and SBS's

is and has been retained by SBS to create work product and on a
work-made-for-hire basis for SBS. Insofar as the authorship and ownership of
all right, title and interest in and to any part of the work product and any
portion of the Intellectual Property are not deemed to vest in or be owned by

agrees to and hereby does during the term assign, sell, transfer, grant and
convey to SBS (without the necessity of any further consideration,
documentation or further acts by either party) the entirety of whatever right,
title and interest Employee has in the Intellectual Property throughout the
Universe. At SBS's request, Employee shall execute any documents reasonably
required by SBS to confirm, establish, record, file applications for, renew or
maintain SBS's rights and ownership in the Intellectual Property worldwide and
will cooperate fully with SBS in connection with any or all of these efforts.

                        (c)     Employee waives any right and claim Employee may
have in any jurisdiction throughout the Universe in or to any moral rights or
rights of "droit moral" with respect to any portion of the Intellectual Property
and confirms that SBS shall have the right, in addition to other rights and
notwithstanding the termination of Employee's employment for any reason, to make
or have made and to own enhancement, derivative works and other modifications
to any part of the Intellectual Property.

                6.      NAME AND LIKENESS.

                        (a)     Use of Name and Likeness.

                        Employee hereby grants to SBS the irrevocable and
exclusive right (whether this Agreement expires in its normal course or is
terminated for any reason whatsoever) during the term of the Agreement
throughout the universe the right to use Employee's name, actual or simulated
likeness, nickname(s), character name(s), slogans, biography and other personal
identification in and in connection with the following uses:

                                (i)     Advertising, publicizing or otherwise
exploiting Employee's



<PAGE>   5

services hereunder, any program or other material in connection with which
Employee renders services hereunder, the results and proceeds of Employee's
services hereunder, and any rights granted to SBS hereunder; and

                                (ii)    Advertising, publicizing or otherwise
exploiting the name, product or services of SBS or any affiliate or any
successor, licensee or assign.

                                (iii)   Section 6(a) is not intended to alter,
compromise or limit in any way SBS's Property Rights as stated in Section 5
above.

                7.      NO OBLIGATION TO PRODUCE OR RELEASE. Notwithstanding any
other provision of this Agreement, SBS shall have no obligation to actually
utilize Employee's services or any of the results and proceeds thereof in any
Program or otherwise, or to produce or exploit any Program, or to exercise any
of the rights granted to SBS hereunder, or to continue any such use, exercise,
production or exploitation, if commenced. SBS's obligations to Employee under
this Agreement shall be fully performed by the payment to Employee of the
applicable compensation provided for in this agreement with respect to which SBS
has guaranteed Employee payment hereunder, subject to all of SBS's rights
hereunder.

                8.      RESOLUTION OF DISPUTES. Employee acknowledges and agrees
that the provisions of Section 4 are reasonable and necessary for protection of
SBS and that SBS will be irrevocably damaged if such provisions are not
specifically enforced. Accordingly, money damages from Employee's breach of
Section 4 would be difficult, if not impossible, to calculate and the most
appropriate relief in the event of Employee's breach would be injunctive relief.
Nothing contained herein shall be deemed to prohibit SBS, for any such breach,
from instituting or prosecuting any other proceeding in any court of competent
jurisdiction, in either law or equity, to obtain damages for any breach of this
Agreement. All remedies given to SBS by this Agreement shall be construed as
cumulative remedies and shall not be alternative or exclusive remedies. In the
event of a breach by Employee of Section 4, Employee agrees to pay to SBS all
costs and expenses, including reasonable attorney's fees, as may be expended by
SBS relative to said breach.

                9.      COMPLIANCE WITH SECTION 508 OF THE COMMUNICATIONS ACT
OF 1934. Employee shall comply with the provisions of Section 508 of the
Communications Act of 1934, as amended, in that he will not accept money or any
valuable consideration, including services, for the broadcast of any matter by
the Stations and in that he will promptly complete the Annual Statement and
Questionnaire and promptly return it to SBS. Without limiting SBS's right to
terminate for any other cause, SBS shall have the right, upon violation of this
provision by Employee, immediately to terminate this Agreement and Employee's
employment hereunder for cause.

                10.     TERMINATION.

                (a)     WITHOUT CAUSE. SBS may terminate this Agreement, without
cause and with prior notice, at any time in which event Employee shall receive
in a lump sum as liquidated damages the equivalent of (12) months' Base Salary
plus any Bonus earned to the date of notice of termination plus health benefits
per COBRA.

                (b)     WITH CAUSE. SBS may terminate this Agreement for cause
at any time upon four (4) weeks prior notice or pay, less withholdings, in lieu
of notice. If Employee is terminated for cause, which shall include, but not be
limited to, termination resulting from (i) death of Employee (ii) misconduct by
Employee as described in (c) below; (iii) Employee disability which prevents
Employee from performing his duties hereunder for six (6) months in any one-year
period, he shall be entitled to only such compensation that has accrued up to
the date of termination and no more.

                (c)     Misconduct by Employee permitting termination for cause
hereunder shall include the following:

                        (i)     failure to comply with any of the terms and
conditions of this Agreement, to perform any reasonable duties assigned by SBS,
to follow any operating policies of SBS, any personnel policies of SBS
(Employee acknowledges having read and understood SBS's Employee policy manual),
to comply with any rule, regulation guideline or policy of the FCC or other
governmental agency with jurisdiction over SBS.

                        (ii)    repeated or sustained absences from the assigned
workplaces;

                        (iii)   conviction of any criminal offense, other than a
traffic violation or minor misdemeanor resulting in incarceration for less than
forty-eight (48) hours;

                        (iv)    any material act of dishonesty which creates or
has a negative effect on SBS

                        (v)     engaging in "payola" or "plugola" practices.

                        (vi)    use of illegal drugs or sustained alcohol abuse,
which is repeated and uncorrected.

                        (vii)   any intentional act that reflects unfavorably
and egregiously on the reputation of SBS.

                        11.     (a)     ASSIGNMENT. SBS shall be entitled to
assign this Agreement to any future licensee of SBS; provided, however, that
such future licensee must agree to be bound by the terms and conditions in this
Agreement. Employee may not assign his obligations under this Agreement.

                                (b)     NOTICE. Any notice or other
