                               THIRD AMENDMENT TO
                      AMENDED AND RESTATED CREDIT AGREEMENT

         THIS THIRD AMENDMENT TO AMENDED AND RESTATED CREDIT AGREEMENT
("Amendment") is made and entered into this 1st day of December, 2002, but
effective as of December 1, 2002 (the "Amendment Date"), by and among XETA
Technologies, Inc., an Oklahoma corporation (the "Borrower"), Bank One,
Oklahoma, N.A., and U.S. Bank National Association, as Lenders under the Credit
Agreement referred to below (the "Lenders"), and Bank One, Oklahoma, N.A., as
Agent (in such capacity, the "Agent"), with reference to the following:

         A. The Borrower, the Lenders and the Agent are parties to that certain
Amended and Restated Credit Agreement dated as of October 31, 2001, as amended
by that certain First Amendment to Amended and Restated Credit Agreement dated
effective as of June 1, 2002, and as further amended by that certain Second
Amendment to Amended and Restated Credit Agreement dated effect as of September
10, 2002 (the "Credit Agreement").

         B. The Borrower has requested that the Lenders and the Agent (i) extend
the availability of the Revolving Credit Facility and the maturity of the
Revolving Loans, and (ii) waive certain Defaults arising by virtue of the
Borrower's failure to comply with certain financial covenants set forth in the
Credit Agreement at October 31, 2002. The Lenders and the Agent have agreed to
the foregoing requests, subject to the terms and conditions set forth in this
Amendment.

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants and agreements herein contained, and for other good and valuable
consideration, the receipt and adequacy of which are hereby acknowledged, the
parties hereby amend the Credit Agreement, effective as of the Amendment Date,
as follows:

1. DEFINITIONS. Capitalized terms used herein (including capitalized terms used
in the recitals above) but not otherwise defined have the respective meanings
assigned to them in the Credit Agreement.

2. WAIVERS. Effective as of the Amendment Date, and subject to the Borrower's
satisfaction of the conditions precedent set forth in Section 4 of this
Amendment, the Lenders and the Agent agree to waive the Borrower's
non-compliance with Sections 6.24.2 (Debt Service Coverage Ratio) of the Credit
Agreement at October 31, 2002, and any consequences of such non-compliance
(other than as set forth in this Amendment). The foregoing waivers do not extend
to any other existing Default or Unmatured Default (whether or not known to the
Borrower, the Lenders or the Agent) or to any Default or Unmatured Default that
may arise or occur after the Amendment Date. Nothing contained in this Amendment
shall be construed as waiving any other term or condition of the Credit
Agreement or any of the other Loan Documents or as obligating the Lenders or the
Agent to waive any future noncompliance or Default.

3. MODIFICATION OF FACILITIES. Effective as of the Amendment Date, and subject
to the Borrower's satisfaction of the conditions precedent set forth in this
Amendment:

         A. Extension of Revolving Credit Facility. The availability of the
Revolving Credit Facility and the maturity of the Revolving Loans are hereby
extended from November 30, 2002 to March 31, 2003. Accordingly, the definition
of the term "Revolving Credit Facility Termination Date" appearing in Section
1.1 of the Credit Agreement is hereby amended by replacing the reference to the
date "October 31, 2002" (as subsequently amended to "November 30, 2002.") with
the date "March 31, 2003."

         B. No Obligation to Grant Further Extensions. The Borrower acknowledges
that, notwithstanding the references in the Credit Agreement and this Amendment
to dates or periods of time subsequent to March 31, 2003, (i) the Lenders will
not be obligated to further extend the availability of the Revolving Credit
Facility, (ii) the Lenders have given no assurances or commitment that any
extension request will be approved, (iii) the Lenders may refuse any extension
request in the exercise of their sole and absolute discretion, and (iv) if any
extension request is approved, the Lenders may condition such approval on the
Borrower's satisfaction of certain requirements, including the making of further
modifications to the Credit Agreement and/or the terms of the Facilities.

         C. Renewal Note. The Borrower agrees to make, execute and deliver to
each Lender a renewal Revolving Note (each, a "Renewal Revolving Note"),
substantially in the form attached hereto as Exhibit "F-1B." The Renewal
Revolving Notes are hereinafter collectively referred to as the "Renewal Notes."
The Renewal Notes shall be in renewal, extension and replacement of, but not in
satisfaction or as a novation of, the respective Notes delivered pursuant to the
Credit Agreement, and from and after the Amendment Date, unless the context
otherwise requires, all references to the "Revolving Notes" appearing in the
Credit Agreement or any other Loan Documents shall mean and refer to the Renewal
Revolving Notes.

4. CONDITIONS PRECEDENT. This Amendment shall become effective as of the
Amendment Date, subject to the Borrower's satisfaction of the following
conditions precedent (in addition to the conditions precedent set forth in
Article IV of the Credit Agreement):

         A. Execution of Documents. The Borrower shall have duly and validly
authorized, executed and delivered to the Agent and the Lenders the following

warranties made by the Borrower in the Credit Agreement and the other Loan

Date (except to the extent any of such representations and warranties with
respect to the financial condition of the Borrower refer to an earlier specified
date).

         E. No Default. There shall not have occurred any additional Default or
Unmatured Default as of the Amendment Date, and the Borrower shall be current in

Agreement (as amended by this Amendment) and the Renewal Notes are valid and
legally binding obligations of the Borrower, enforceable in accordance with
their respective terms, except as limited by applicable bankruptcy, insolvency
or other laws affecting the enforcement of creditors' rights generally.

         C. No Conflict; Government Consent. Neither the execution and delivery
by the Borrower of this Amendment and the Renewal Notes, nor the consummation of
the transactions therein contemplated, nor compliance with the provisions
thereof, will violate (i) any law, rule, regulation, order, writ, judgment,
injunction, decree or award binding on the Borrower or any of its Subsidiaries,
or (ii) the Borrower's or any Subsidiary's articles or certificate of
incorporation, partnership agreement, certificate of partnership, articles or
certificate of organization, by-laws, or operating or other management
agreement, as the case may be, or (iii) the provisions of any indenture,
instrument or agreement to which the Borrower or any of its Subsidiaries is a

imposition of any Lien in, of or on the

Property of the Borrower or any of its Subsidiaries pursuant to the terms of any
such indenture, instrument or agreement. No order, consent, adjudication,
approval, license, authorization, or validation of, or filing, recording or
registration with, or exemption by, or other action in respect of any
governmental or public body or authority, or any subdivision thereof, which has
not been obtained by the Borrower or any of its Subsidiaries, is required to be
obtained by the Borrower or any of its Subsidiaries in connection with the
execution and delivery of this Amendment, the borrowings under the Credit

latest financial statements of the Borrower which have been delivered to the
Agent and the Lenders), there has been no adverse change in the business,
Property, prospects, condition (financial or otherwise) or results of operations
of the Borrower and its Subsidiaries which could reasonably be expected to have
a Material Adverse Effect.

of any irreconcilable inconsistency between the terms of this Amendment and the
terms of the Credit Agreement, the terms of this Amendment shall control and
govern, and the agreements shall be interpreted so as to carry out and give full
effect to the intent of this Amendment. All references to the "Credit Agreement"
appearing in any of the Loan Documents shall hereafter be deemed references to
the Credit Agreement as amended, modified and supplemented by this Amendment.

debts, accounts, conveyances, agreements, damages, claims, demands, liabilities,
costs, and expenses of whatsoever kind or nature, including attorney's fees, in

arising or accruing, which the Borrower may now have or may claim to have
against the parties released or any of them, including, without limitation,
