                                                                  Execution Copy

                            SHARED SERVICES AGREEMENT

     This Shared Services Agreement ("Agreement") is entered into as of April 1,
2002 by and between Mission Broadcasting of Joplin, Inc., a Delaware corporation
("Mission"), and Nexstar Broadcasting of Joplin, L.L.C. ("Nexstar"), a Delaware
limited liability company. Mission and Nexstar are referred to collectively as
the "Parties."

     WHEREAS, Mission provides programming to television broadcast station
KODE-TV, Joplin, Missouri ("KODE"), pursuant to a Time Brokerage Agreement, and
has entered into a Purchase and Sale Agreement with GOCOM Broadcasting of
Joplin, LLC and GOCOM of Joplin License Sub, LLC (collectively, "GOCOM"),
pursuant to which it has agreed to acquire substantially all of the assets of
KODE, both agreements being dated as of December 31, 2001. Television station
KSNF-TV, Joplin, Missouri ("KSNF") is owned and operated by Nexstar.

     WHEREAS, KODE and KSNF are collectively referred to as the "Stations."

     NOW, THEREFORE, for their mutual benefit and in order to enhance the
respective abilities of Nexstar and Mission to compete with other television and
media outlets serving the Joplin, Missouri market, Nexstar and Mission agree as
follows:

     1. SHARING ARRANGEMENTS GENERALLY. From time to time, Nexstar and Mission
may agree to share the costs of certain services and procurements which they
individually require in connection with the operation of the Stations. Such
sharing arrangements may take the form of joint or cooperative buying
arrangements, or the performance of certain functions relating to the operation
of one Station by employees of the operator of the other Station (subject in all
events to the supervision and control of personnel of the operator of the
Station to which such functions relate), or may be otherwise structured, and
will be governed by terms and conditions upon which Nexstar and Mission may
agree from time to time, subject to the consent of GOCOM prior to the purchase
of KODE by Mission (such consent not to be unreasonably withheld). Such sharing
arrangements may include the co-location of the studio, non-managerial
administrative and/or master control and technical facilities of the Stations
and the sharing of grounds keeping, maintenance, security and other services
relating to those facilities. In performing services under any such sharing
arrangement (including those described in Section 4), personnel of one Party
will be afforded access to, and have the right to utilize, without charge,
assets and properties of the other Party to the extent necessary or desirable in
the performance of such services.

     2. CERTAIN SERVICES NOT TO BE SHARED.

          (a) Senior Management Personnel. At all times, each Station will have
personnel performing the typical functions of a general manager and a business
manager. Such

<PAGE>

personnel will (i) be retained solely by the Party which owns and/or provides
programming to such Station and will report solely to such Party, and (ii) have
no involvement or responsibility in respect of the operation of the other
Station.

          (b) Programming and Sales. Each Party will maintain for the Station
operated or programmed by it separate managerial and other personnel to carry
out the selection and procurement of programming for such Station and the
pricing and selling of commercial and advertising time on such Station, and in
no event will the Parties or the Stations share services, personnel, or
information pertaining to such matters, except as set forth in Section 4(f)(i)
below.

     3. GENERAL PRINCIPLES GOVERNING SHARING ARRANGEMENTS. All arrangements
contemplated by this Agreement will be subject to, and are intended to comply in
all respects with, the Communications Act of 1934, as amended, the rules,
regulations and policies of the Federal Communications Commission (the "FCC"),
as in effect from time to time (the "FCC Rules and Regulations"), and all other
applicable laws. The arrangements made pursuant to this Agreement will not be
deemed to constitute "joint sales," "program services," "time brokerage," "local
marketing," or similar arrangements or a partnership, joint venture, or agency
relationship between the Parties or the Stations, and no such arrangement will
be deemed to give either Party any right to control the policies, operations,
management or any other matter relating to the Station owned and/or programmed
by the other Party.

     4. CERTAIN SPECIFIC SHARING ARRANGEMENTS. In furtherance of the general
agreements set forth in Sections 1 through 3 above, Nexstar and Mission have
agreed as follows with respect to the sharing of certain services:

          (a) Execution of Promotional Policies. Nexstar personnel will
implement and execute the promotional policy developed by Nexstar personnel for
KSNF from time to time. Subject to direction and control by Mission management
personnel, Nexstar personnel will also execute the promotional policy for KODE.
Such execution will include such tasks as graphic design, production and media
placement and buying.

          (b) Continuity and Traffic Support. Nexstar personnel will carry out
continuity and other tasks necessary to support management personnel and
functions for KSNF. Subject to direction and control by management personnel of
Mission, Nexstar personnel will also carry out continuity and such other tasks
with respect to KODE.

          (c) Master Control. Master control operators and related employees of
Nexstar may carry out master control functions for KODE subject to the direction
and control of Mission.

          (d) Payable Support. Nexstar personnel will not engage in the payment
of accounts payable of Mission arising under contracts for the license of
programming run or to be run on KODE, the payment of Mission's payroll with
respect to KODE, or other obligations of Mission incurred in the normal course
of business.

<PAGE>

          (e) Transmission Facilities Maintenance. Nexstar personnel will
maintain and repair (as needed) the transmission facilities of KSNF. Subject to
direction and control by Mission management personnel, Nexstar personnel,
subject to the consent of GOCOM prior to the purchase of KODE by Mission (such
consent not to be unreasonably withheld), will also maintain and repair (as
needed) the transmission facilities of KODE.

          (f) Newscast Production.

              (i) Production and Delivery. Utilizing KSNF management personnel
and facilities, Nexstar may provide live-feed, fully-staffed and produced
newscasts for broadcast on KODE at such times as Mission may request from time
to time by reasonable advance notice to Nexstar; provided that such newscasts
will not comprise more than 15% (by duration) of the programming broadcast on
KODE during any broadcast day. Nexstar will be responsible for delivering such
newscasts to KODE's broadcast facilities. Mission shall make available to
Nexstar (A) such space in the KODE studio and facilities as may be reasonably
necessary to produce such newscasts, (B) such non-management-level news
personnel as may be necessary to produce such newscasts, and (C) such technical
facilities of KODE as may be necessary to produce such newscasts and to deliver
such newscasts to KODE's transmission facilities. Nexstar will use reasonable
efforts to provide that such newscasts are of a quality appropriate to KODE's
market. Such newscasts will be produced exclusively for Mission for broadcast on
KODE, but may include non-exclusive videotape, graphics, news stories, field
reports and other material. Mission personnel will determine the title and
format of such newscasts, and such newscasts will have an "on-air appearance" as
if they had been originated by Mission through KODE.

              (ii) Commercial, Advertising and Promotional Spots. Mission will
determine the amount of commercial advertising time and promotional time to be
provided for during such newscasts. Mission will have the exclusive right to
sell commercial advertising time during such newscasts and will retain all
revenue from the sale of such commercial advertising time.

              (iii) Editorial Control and Responsibility. Nexstar will use
reasonable efforts to maintain a system of editorial review to ensure the
accuracy, prior to broadcast, of all investigative reports and other stories
prepared by Nexstar personnel and included in the newscasts which Nexstar
provides to Mission. Each Party will maintain the following types of insurance
coverage for no less than the indicated amounts and will deliver to the other
Party upon request a certificate of insurance showing the following: (A)
comprehensive general liability insurance in an amount of $1,000,000; (B)
worker's compensation and/or disability insurance; and (C)
libel/defamation/First Amendment liability insurance, with a deductible of no
more than $100,000, as to which coverage each Party will name the other party as
an additional insured.

              (iv) ABC News Feeds. Subject to Nexstar, Mission and ABC
Broadcasting Company entering into a news sharing agreement in form and
substance agreeable to the parties thereto, Nexstar will be free to utilize, at
its discretion, the ABC Network News feed footage in the newscasts it produces
for Mission.

              (v) Operating Procedures Agreement. Nexstar and Mission will

<PAGE>

collaborate to create a newscast operating agreement or procedural memo which
will provide the basis for daily operations, contingencies, KODE's access to
breaking stories, procedures for editorial compliance with FCC Rules and
Regulations (including quarterly programs/issues requirements), regularly
scheduled operations, editorial and ratings reviews and guidelines for access by
Mission personnel and KODE customers to Nexstar's facilities.

          (g) Services Fee. In consideration for the services to be provided to
KODE by Nexstar personnel as described in Sections 4(a) through 4(f), Mission
will pay to Nexstar the fee (the "Services Fee") described in this Section 4(g).

              (i) Base Amount. Subject to the remaining provisions of this
Section 4(g), the base amount of the Services Fee during any calendar year will
be determined in accordance with Section 4(g)(iii), in the case of calendar year
2001, and will be 110% of the Services Fee during the preceding year (without
regard to any deferral of the Services Fee for such preceding year pursuant to
Section 4(g)(ii), and in the case of calendar year 2002, without regard to the
proration of the Services Fee for calendar year 2001), in the case of each
subsequent year.

              (ii) Deferral. Payment and accrual of the Services Fee in respect
of any calendar year (or partial calendar year, in the case of the calendar
years during which the sharing of services described in Section 4(a) through
4(f) commences and ceases) will be deferred to the extent that the amount of the
Services Fee which otherwise would be payable for such period would exceed
KODE's Available Cash Flow (as that term is defined in Section 4(g)(iv)) for
such period; provided that an amount equal to the amount so deferred in respect
of any calendar year or partial calendar year will be added to the base amount
of the Services Fee for the following calendar year or partial calendar year. In
addition, upon a termination of this Agreement pursuant to clause (i) of Section
7, the entire amount of the Services Fee which has accrued and is unpaid as of
the Cessation Date (as that term is defined in Section 7) will be waived.

              (iii) Payment Terms. The Services Fee will be payable monthly in
equal installments during each calendar year from and after the month during
which this Agreement is executed, and will be prorated on a daily basis for
calendar year 2001 and the calendar year during which the sharing arrangements
described in Sections 4(a) through 4(f) are terminated. These monthly payments
will be based upon Mission's good-faith estimate of the non-deferred amount of
the Services Fee for each year or partial year (based on its good faith estimate
of the Available Cash Flow for that year or partial year), consistent with the
principle that such non-deferred amount of the Services Fee shall be equal to
90% of KODE's Available Cash Flow for that year or partial year. At the
conclusion of each calendar year, when the actual amount of KODE's Available
Cash Flow for that year or partial year is established, Nexstar will pay to
Mission or Mission will pay to Nexstar, as the case may be, any additional
amounts as may be necessary to give effect to any deferral of Services Fees
pursuant to Section 4(g)(ii).

              (iv) Available Cash Flow Defined. For any period, KODE's
"Available Cash Flow" means Mission's broadcast cash flow in respect of KODE for
such period (determined without deduction for the Service Fee), reduced by the
following, without duplication:

<PAGE>

                    (A) the aggregate amount of all cash paid by Mission in
respect of reasonable capital expenditures relating to KODE during such period,

                    (B) the aggregate amount of all cash payments required to be
made by Mission during such period in respect of the principal amount of, and
interest on, indebtedness of Mission for borrowed money incurred in respect of
KODE, and

                    (C) the aggregate amount of all cash payments made by
Mission during such period in respect of federal, state and local taxes, in each
case to the extent not reflected in such broadcast cash flow for such period or
any prior period, and increased or reduced as Mission and Nexstar may reasonably
agree is appropriate in light of the reduction or increase in the non-cash net
working capital of Mission in respect of KODE during such period.

     5. FORCE MAJEURE. If a force majeure event such as a strike, labor dispute,
fire, flood or other act of God, failure or delay of technical equipment, war,
public disaster, or other reason beyond the cause or control of Nexstar or
Mission prevents such Party or its personnel from performing tasks which it is
required to perform under this Agreement during any period of time, then such
failure will not be a breach of this Agreement and such Party will be excused
from such performance during that time.

     6. UNENFORCEABILITY. If any provision of this Agreement or the application
thereof to any person or circumstances shall be invalid or unenforceable to any
extent, the remainder of this Agreement and the application of such provision to
other persons or circumstances shall not be affected thereby and shall be
enforced to the greatest extent permitted by law, except that if such invalidity
or unenforceability should change the basic economic positions of the Parties,
they shall negotiate in good faith such changes in other terms as shall be
practicable in order to restore them to their prior positions. In the event that
the FCC alters or modifies its rules or policies in a fashion which would raise
substantial and material questions as to the validity of any provision of this
Agreement, the Parties shall negotiate in good faith to revise any such
provision of this Agreement in an effort to comply with all applicable FCC Rules
and Regulations, while attempting to preserve the intent of the Parties as
embodied in the provisions of this Agreement. The Parties agree that, upon the
request of either of them, they will join in requesting the view of the staff of
the FCC, to the extent necessary, with respect to the revision of any provision
of this Agreement in accordance with the foregoing. If the Parties are unable to
negotiate a mutually acceptable modified Agreement, then either party may
terminate this Agreement upon written notice to the other. Upon such
termination, Mission shall pay to Nexstar all accrued and unpaid Service Fees
and each Party shall be relieved of any further obligations, one to the other.

     7. TERM OF SHARING ARRANGEMENTS. The term of this Agreement shall commence
on the date of execution of this Agreement. The initial term of this Agreement
is ten (10) years. Unless otherwise terminated by either Party, the term of this
Agreement shall be extended for an additional ten (10) year term. Either Party
may terminate this Agreement at the end of the initial ten year term by six
months prior written notice to the other. Notwithstanding the foregoing, the
sharing arrangements contemplated by this Agreement will terminate (i) upon the
termination of the TBA other than in connection with the consummation of the
transactions contemplated by the

<PAGE>

Purchase Agreement, (ii) upon the consummation of the purchase and sale of
assets of Mission relating to KODE by Nexstar, or an assignee of Nexstar, under
the terms of a certain Option Agreement (the "Option Agreement") entered into by
Mission and Nexstar or an affiliate of Nexstar (the "Optionee"), or (iii) at
Nexstar's option, if the assets of Mission relating to KODE are sold to a party
other than Optionee (in any case, the date upon which such termination occurs
being the "Cessation Date"). Except as provided in Section 4(g)(ii), no
termination of this Agreement, whether pursuant to this Section 7 or otherwise,
will affect Mission's duty to pay any Services Fee accrued, or to reimburse any
cost or expense incurred, prior to the effective date of that termination.

     8. INDEMNIFICATION.

          (a) Nexstar's Indemnification of Mission. Nexstar will indemnify and
hold harmless Mission and Mission's employees, agents, officers and contractors
from and against any and all liability, claims, losses, damages and causes of
action including but not limited to reasonable attorney's fees (collectively,
"Losses") arising out of or related to (i) any material breach or default by
Nexstar of any of its representations, warranties, covenants or agreements made
in this Agreement, and (ii) the newscasts provided by Nexstar. Without limiting
the generality of the foregoing, Nexstar will indemnify and hold harmless
Mission and Mission's employees, agents, officers and contractors from and
against any and all Losses for libel and slander, infringement of trademarks,
service marks or trade names, invasion or violation of rights of privacy or
infringement of copyrights and other proprietary rights resulting from the
newscasts provided by Nexstar. Nexstar's obligation to indemnify and hold
harmless Mission and Mission's employees, agents, officers and contractors from
and against the Losses specified above shall survive any termination of this
Agreement until the expiration of all applicable statutes of limitation.

          (b)  Mission's Indemnification of Nexstar. Mission will indemnify and
               hold harmless Nexstar and Nexstar's employees, agents, officers
               and contractors from and against any and all Losses arising out
               of or related to (i) any material breach or default by Mission of
               any of its representations, warranties, covenants or agreements
               made in this Agreement, and (ii) any programming or commercial
               advertisements provided, furnished or sold by Mission. Without
               limiting the generality of the foregoing, Mission will indemnify
               and hold harmless Nexstar and Nexstar's employees, agents,
               officers and contractors from and against any and all Losses for
               libel and slander, infringement of trademarks, service marks or
               trade names, invasion or violation of rights of privacy or
               infringement of copyrights and other proprietary rights resulting
               from programming or commercial advertisements provided, furnished
               or sold by Mission. Mission's obligation to indemnify and hold
               harmless Nexstar and Nexstar's employees, agents, officers and
               contractors from and against the Losses specified above shall
               survive any termination of this Agreement until the expiration of
               all applicable statutes of limitation.

jurisdiction other than the State of Missouri. In furtherance of the foregoing,
the internal law of the State of Missouri will control the interpretation and
