                                           As of December 1, 2000

Mr. Philip M. Stolz
c/o Hearst-Argyle Television, Inc.
888 Seventh Avenue
New York, NY 10106

Dear Phil:

     This letter constitutes all of the terms of the Employment Agreement
between you and Hearst-Argyle Television, Inc. ("Hearst-Argyle").  It is subject
to the approval of the Board of Directors of Hearst-Argyle.  The terms are as
follows:

     1.   Legal Name of Employee: Philip M. Stolz

     2.   Mailing Address of Employee: c/o Hearst-Argyle Television, Inc.,
          888 Seventh Avenue, New York, NY 10106

     3.   Title of Position; Duties:   Senior Vice President, Group Head.

You agree to carry out the duties assigned to you by the Chief Executive Officer
of Hearst-Argyle.  Hearst-Argyle has the right to assign you to other duties
consistent with those of other executives of your level.

     4.   Length of Employment. The term of this Agreement will start on January
1, 2001 and continue through December 31, 2002 (the "Term").

     5.   Salary.  You will receive a base salary for all services to Hearst-
Argyle as follows:

          a)   $415,000 per year during calendar year 2001; and

          b)   $430,000 per year during calendar year 2002.
<PAGE>

     The salary will be paid according to Hearst-Argyle's payroll practices, but
not less frequently than twice a month.  You acknowledge that you are not
entitled to overtime pay.

     In addition it is understood that you are eligible to receive a bonus that
will have a target of 40% of your base salary and a maximum of 75% of your base
salary.  The criteria for the bonus will be set by the Compensation Committee of
the Board of Directors of Hearst-Argyle, at its sole discretion.

     The bonus is payable only for as long as you work for Hearst-Argyle, and
will be payable only at the end of a complete bonus cycle and is not proratable,
except in the event of your death, when it will be proratable.

     In determining the amount of your bonus, the books and records of Hearst-
Argyle are absolute and final and not open to dispute by you.  Hearst-Argyle
will pay any bonus due you by March 31 of the year following the year for which
the bonus is applicable.

     6.  Exclusive Services.  You agree that you will work only for Hearst-

to anyone else, without getting Hearst-Argyle's written approval.  However, you
may participate as a member of the board of directors of other organizations and
in charitable and community organizations, but only if such activities do not
conflict or interfere with your work for Hearst-Argyle, and if such work is
approved in advance by Hearst-Argyle, which approval will not be unreasonably
withheld.  You acknowledge that your services will be unique, special and
original and will be financially and competitively valuable to Hearst-Argyle,
and that your violation of this paragraph will cause Hearst-Argyle irreparable
harm for which money damages alone would not adequately compensate Hearst-
Argyle.  Accordingly, you acknowledge that if you violate this paragraph,
Hearst-Argyle has the right to apply for and obtain injunctive relief to stop
such
<PAGE>

violation, in addition to any other appropriate rights and remedies it might
lawfully have.

contract, written or otherwise, with another employer.

               failure to carry out, or neglect or misconduct in the performance
               of, your duties hereunder or a breach of this Agreement; (iii)
               willful failure to comply with applicable laws with respect to
               the conduct of Hearst-Argyle's business, (iv) theft, fraud or

so is a violation of law as well as a cause for termination. Also, you agree

this Agreement without first talking with Hearst-Argyle about your intentions
and obtaining Hearst-Argyle's written consent.

will surrender to Hearst-Argyle at the end of your employment all its property

apply for and obtain injunctive relief to stop such a violation, in addition to
its other legal remedies, as outlined in Paragraph 6.

     You agree to keep the terms of this Agreement confidential from everybody
except your professional advisors and family.

     11.  Non-Solicitation; Non-Hire. You agree that for two (2) years after the

agency or advertiser of Hearst-Argyle, its subsidiaries or affiliates to
terminate such relationship or to stop doing business with Hearst-Argyle, its
subsidiaries or affiliates.

     If you violate this provision, Hearst-Argyle will have the same right to
injunctive relief as outlined in Paragraph 6, as well as any other remedies it
may have.  If any court of competent jurisdiction finds any part of this
paragraph unenforceable as to its duration, scope or geographic area, it shall
be deemed amended to conform to the scope that would permit

terminate upon the expiration of the Term (unless terminated earlier pursuant to

extension then this Agreement shall continue on a month-to-month basis until the
earlier of (i) the commencement of a renewal or extension agreement between you
