      A. Dobson Communications Corporation ("COMMUNICATIONS") proposes to enter
into a Capital Lease for the acquisition of furniture and equipment for its
headquarters building in Oklahoma City, Oklahoma.

      B. SECTION 9.30 prohibits Communications from incurring Debt (including
obligations under Capital Leases) or creating Liens, other than as specifically
permitted in such Section.

      C. In addition, DOC has requested that the permitted Capital Expenditures
for calendar year 2001, in SECTION 9.29(E) be increased from $80,000,000 to
$109,000,000.

      D. DOC and Communications have requested amendments to SECTIONS 9.20,
9.29, and 9.30 to (a) permit Communications to enter into Capital Leases up to
an aggregate amount of $12,000,000, (b) permit Restricted Payments, loans,
advances, or investments from Borrower to Communications for the purpose of
servicing such permitted Capital Leases, and (c) increase the amount of
permitted Capital Expenditures for calendar year 2001, and Required Lenders are
willing to grant and agree to such amendments, but only upon the conditions,
among other things, that DOC, Guarantors, and Required Lenders shall have
executed and delivered this Amendment and shall have agreed to the terms and
conditions of this Amendment.

      NOW, THEREFORE, in consideration of these premises and other valuable
consideration, the receipt and adequacy of which are hereby acknowledged, the
parties hereto agree, as follows:

PARAGRAPH 1. AMENDMENTS.

      1.1 LOANS, ADVANCES, INVESTMENTS, AND RESTRICTED PAYMENTS. SECTION 9.20 is
amended by (a) deleting the word "and" after CLAUSE (t) thereof, and (b)
changing the period (.) at the end of CLAUSE (u) thereof to a semicolon (;) and
inserting the following after the semicolon:
<PAGE>
            "and (v) Restricted Payments, loans, advances, or investments made
            by Borrower to Communications in an amount sufficient to pay
            regularly-scheduled payments on the Capital Leases of Communications
            to the extent such Capital Lease is permitted by SECTION
            9.30(a)(v)."

      1.2 CAPITAL EXPENDITURES. The Capital Expenditures limitation in SECTION
9.29(e) is amended by deleting the reference to "$80,000,000" in the chart
thereof and substituting therefor the amount "$109,000,000" and (ii) deleting
the reference to "$100,000,000" in line 5 of the proviso thereto and
substituting therefor the amount "$120,000,000".

      1.3 COVENANTS OF COMMUNICATIONS.

      (a) SECTION 9.30(a) is amended by (a) deleting the word "and" after CLAUSE
(III) thereof, and (b) changing the period (.) at the end of CLAUSE (IV) thereof
to a semicolon (;) and inserting the following after the semicolon:

            "and (v) Debt of Communications arising under Capital Leases in an
            amount not to exceed $12,000,000 in the aggregate' provided that,
            (A) such Capital Leases contain covenants no more restrictive than
            the covenants in this Agreement and (B) prior to the incurrence of
            such Debt, Administrative Agent receives an opinion of counsel
            acceptable to Administrative Agent addressed to Administrative Agent
            and the Lenders that execution and performance of such Capital Lease
            does not constitute a "default" or "event of default" or other
            breach or noncompliance with the terms and provisions of the
            Communications Bond Debt, the Exchange Debentures, or the Preferred
            Stock, including any event which would create voting rights in the
            holders of the Preferred Stock."

      (b) SECTION 9.30(d) is amended (a) deleting the word "and" after CLAUSE
(VI) thereof, and (b) changing the period (.) at the end of CLAUSE (VII) thereof
to a semicolon (;) and inserting the following after the semicolon:

            "and (viii) Liens securing Capital Leases permitted by SECTION
            9.30(a)(v), so long as any such Lien does not extend to any asset
            other than the asset financed by such Capital Lease."

      (c) SECTION 9.30(e) is amended by deleting the parenthetical therein in
its entirety and substituting therefor the follow:

            "(other than Restricted Payments, loans, advances, or investments
            made pursuant to SECTIONS 9.20(p), (q), (s), (t), (u), or (v))"

PARAGRAPH 2. CONDITIONS. Notwithstanding any contrary provision, this Amendment
is not effective until the date upon which (a) the representations and
warranties in this Amendment are true and correct; and (b) Administrative Agent

delivery, and effectiveness of this Amendment shall not, except as expressly
provided herein, operate as a waiver of any Rights of Lenders under any Loan
Document, nor constitute a waiver under any of the Loan Documents.

PARAGRAPH 7. ENTIRETIES. THIS AMENDMENT REPRESENTS THE FINAL AGREEMENT BETWEEN
THE PARTIES ABOUT THE SUBJECT MATTER OF THIS AMENDMENT AND MAY NOT BE
