          FIRST AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT AND
                                 LIMITED CONSENT

            THIS FIRST AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT AND
LIMITED CONSENT (this "Amendment"), dated as of November 14, 2001, among NEXSTAR
FINANCE, L.L.C., a Delaware limited liability company (the "Borrower"), NEXSTAR
BROADCASTING GROUP, L.L.C., a Delaware limited liability company (the "Ultimate
Parent"), the other Parent Guarantors (as such term is defined in the
hereinafter described Credit Agreement) parties to this Amendment, the several
Banks (as such term is defined in the hereinafter described Credit Agreement)
parties to this Amendment, and BANK OF AMERICA, N.A., as Administrative Agent
for the Banks (in such capacity, the "Administrative Agent").

                                R E C I T A L S:

      A. The Borrower, the Ultimate Parent, the other Parent Guarantors, the
Administrative Agent, Barclays Bank PLC, as Syndication Agent, First Union
National Bank, as Documentation Agent, and the several Banks parties thereto
entered into that certain Amended and Restated Credit Agreement dated as of June
14, 2001 (as the same may be amended, modified, restated, supplemented, renewed,
extended, increased, rearranged and/or substituted from time to time, the
"Credit Agreement"). Capitalized terms used and not otherwise defined herein
shall have the meanings ascribed to them in the Credit Agreement.

      B. The Borrower has advised the Lenders that the Parent Guarantors and the
Borrower do not anticipate to be in compliance with the financial covenant set
forth in Section 8.09(a) of the Credit Agreement with respect to the Measurement
Period ended September 30, 2001 (such anticipated noncompliance is hereinafter
referred to as the "Financial Covenant Default").

      C. Pursuant to Section 9.02 of the Credit Agreement, if at the end of any
Fiscal Quarter there exists an Event of Default with respect to Section 8.09(a),
the Borrower may, prior to the date upon which financial statements for such
Fiscal Quarter are required to be delivered pursuant to Section 7.01, cure such
Event of Default by receiving equity contributions from ABRY L.P. II, ABRY L.P.
III and/or Sook (and/or other Persons exercising preemptive rights in connection
with an equity issuance to one or more of them), or a payment pursuant to an
ABRY Capital Contribution Agreement, and applying the proceeds therefrom to
repay Loans and/or to reduce Commitments so that the Consolidated Total Leverage
Ratio, calculated on a Pro Forma Basis after giving effect to any such equity
contributions and repayments, as of the last day of the Fiscal Quarter for which
such Event of Default occurred, do not exceed the ratio set forth in Section
8.09(a).

      D. The Administrative Agent has requested that ABRY L.P. III make a cash
equity contribution of $5,000,000 in immediately available funds to the Ultimate
Parent as required by Section 2(a) of the ABRY Capital Contribution Agreement.

<PAGE>

      E. In satisfaction of Section 2(a) of the ABRY Capital Contribution
Agreement and in order to cure the Financial Covenant Default pursuant to
Section 9.02 of the Credit Agreement, ABRY L.P. II and/or ABRY L.P. III have
proposed purchasing Permitted Parent Preferred Equity (the "Additional Parent
Equity") for an aggregate cash purchase price of $15,000,000 in immediately
available funds on or before the Amendment Effective Date, $5,000,000 of the
proceeds of which shall be used to make a mandatory prepayment of Term Loans
pursuant to Section 2.07(h) of the Credit Agreement to be applied pursuant
Sections 2.07(k), 2.08(b) and 9.02 thereof, and $10,000,000 of the proceeds of
which shall be used to make a voluntary prepayment of Term Loans pursuant to
Section 2.06 of the Credit Agreement to be applied pursuant Sections 2.06(c),
2.08(b) and 9.02 thereof.

      F. The consent of the Majority Banks is required in order to allow the
issuance of the Additional Parent Equity pursuant to Section 8.05(l) of the
Credit Agreement inasmuch as the Financial Covenant Default exists prior to such
issuance and pursuant Section 8.14(ii) of the Credit Agreement inasmuch as
certain amendments to the Charter Documents of the Ultimate Parent are required
to authorize the issuance of the Additional Parent Equity.

      G. The Borrower and the Ultimate Parent have further advised the
Administrative Agent that they wish to effect the following transactions:

            (i) the execution, delivery and performance by Nexstar Broadcasting
      of Peoria, L.L.C. ("Nexstar Peoria") of an Outsourcing Agreement with
      WYZZ, Inc. with respect to commercial television broadcast station WYZZ,
      Peoria-Bloomington, Illinois, substantially in the form previously
      provided by the Borrower to the Administrative Agent (the "Outsourcing
      Agreement");

            (ii) the guaranty by the Ultimate Parent of certain lease
      obligations of Mission Broadcasting of Joplin, Inc., a Delaware
      corporation ("Mission Joplin"), to SpectraSite Broadcast Towers, Inc. in
      connection with the acquisition by Mission Joplin of commercial television
      broadcast station KODE-TV, Joplin, Missouri (the "Station"), which
      Guaranty Obligations shall be incurred pursuant to documentation
      substantially in the form previously provided by the Borrower to the
      Administrative Agent (such guaranties are hereinafter referred to
      collectively as the "SpectraSite Lease Guaranties"); and

            (iii) the execution, delivery and performance by Nexstar
      Broadcasting of Joplin L.L.C. ("Nexstar Joplin") of a Shared Services
      Agreement with Mission Joplin with respect to the Station substantially in
      the form previously provided by the Borrowers to the Administrative Agent
      (the "KODE SSA").

      H. The written consent of Majority Banks is required prior to the
execution, delivery and performance of the Outsourcing Agreement and the KODE
SSA pursuant to Section 8.04(b) of the Credit Agreement inasmuch as the
Consolidated Total Leverage Ratio immediately prior to the consummation of such
transaction is greater than 5:00:1:00.


                                       2

      I. The amendment of Section 8.05 of the Credit Agreement is required prior
to the execution and delivery of the SpectraSite Lease Guaranties inasmuch as
the incurrence of the Guaranty Obligations thereunder is not otherwise permitted

      J. The Borrower and the Ultimate Parent have requested that the Banks (i)
consent to the issuance of the Additional Parent Equity notwithstanding the

the Charter Documents of the Ultimate Parent in order to permit such issuance,
(iii) consent to the execution, delivery and performance of the Outsourcing
Agreement and the KODE SSA, (iv) amend the Credit Agreement to permit the

certain financial covenants in order to assist the Credit Parties with future
compliance with such covenants, in each case as more fully described
hereinbelow.

      K. The several Banks parties to this Amendment are willing to (i) consent
to the issuance of the Additional Parent Equity notwithstanding the existence of

Documents of the Ultimate Parent in order to permit such issuance, (iii) consent
to the execution, delivery and performance of the Outsourcing Agreement and the

each of the covenants, terms and conditions, and in reliance upon all of the
representations and warranties of the Borrower and the Ultimate Parent, set
forth herein.

      NOW, THEREFORE, in consideration of the premises and the covenants, terms,
conditions, representations and warranties herein contained, the parties hereto
agree hereby as follows:

      Revolving Loans) which are Eurodollar Loans, the margin to be added at any
      date to the Eurodollar Rate, which is equal to the applicable percentage
      rate per annum set forth below, based upon the applicable Level in effect
      for the Borrower on such date; (ii) with respect to Term A Loans (other
      than Incremental Term Loans) and Revolving Loans (other than Incremental
      Revolving Loans) which are Base Rate Loans, the margin to be added at any
      date to the Base Rate, which is equal to the percentage per annum which is
      1.625% less than the Applicable Margin for Eurodollar Loans then in effect
      for the Borrower on such date, but in no event less than zero, (iii) with
      respect to Term B Loans which are Eurodollar Loans, (x) while the
      applicable Level in effect for the Borrower is Level VII,

      4.250% , and (y) at all other times, 4.000%; (iv) with respect to Term B
      Loans which are Base Rate Loans, 1.625% less than the Applicable Margin
      for Term B Loans which are Eurodollar Loans then in effect for the
      Borrower on such date, but in no event less than zero; and (iv) with
      respect to Incremental Term Loans and Incremental Revolving Loans, the
      Incremental Margin to be added to the Base Rate or Eurodollar Rate, as the
      case may be, as agreed upon by the Borrower and the Bank or Banks

      Commitment relating thereto as provided in Section 2.16(a), or if not

      shall include only payments actually received or currently receivable by
      such Person under such agreements during such period (regardless of the
      GAAP treatment thereof) for the purpose of calculating such Person's
      Consolidated Operating Cash Flow for such period."

      (c) Section 1.01 is amended by deleting the definition of "Level" and
inserting the following definition in lieu thereof:

            "Level" means, as of any date of determination, the applicable Level

      of calculating the Applicable Margin shall be deemed to be Level VI, after
      November 13, 2001, through and including the day immediately preceding the

      purposes of calculating the Applicable Margin shall be deemed to be Level
      VII and for each period thereafter beginning on an Adjustment Date and
      ending on the day immediately preceding the next succeeding Adjustment

      the applicable Level set forth below opposite the Consolidated Total
      Leverage Ratio determined as at the end of the last Fiscal Quarter ended
      prior to the first day of such period. If by any Adjustment Date, the
      Borrower has failed to deliver a Compliance Certificate for the then most
      recently completed Fiscal Quarter, the Applicable Margin for the next
      succeeding period commencing on such Adjustment Date and ending on the
      second Business Day after such Compliance Certificate is actually
      delivered shall be computed as if the Consolidated Total Leverage Ratio
      were at Level VII.
