ITEM 4. DESCRIPTION OF SECURITIES.

          Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

          The legality of the issuance of the shares of Common Stock offered
hereby has been passed upon for the Company by the firm of Barber & Bartz, a
Professional Corporation, which serves as general counsel to the Company. Ron B.
Barber, senior shareholder of the firm, is a director of the Company and
beneficially owns approximately 1.25% of the Company's outstanding Common Stock.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          The Oklahoma General Corporation Act (the "OGCA") and the Company's
Bylaws each contain provisions for indemnification of officers and directors of
the Company against liability incurred by them under certain circumstances in
their capacities as officers and directors of the Company.

          The OGCA and the Company's Bylaws provide for indemnification of its
officers and directors against expenses (including attorneys' fees, judgments,
fines and amounts paid in settlement) actually and reasonably incurred in
connection with the defense of any threatened, pending or completed legal
proceeding in which the officer or director is a party or threatened to be made
a party by reason of the fact that he is or was a director or officer of the
Company, if he acted in good faith and in a manner that he reasonably believed
to be in, or not opposed to, the best interests of the Company, and, with
respect to any criminal action or proceeding, if he had no reasonable cause to
believe that his conduct was unlawful. If the legal proceeding, however, is by
or in the right of the Company, the director or officer may not be indemnified
in respect of any claim, issue or matter as to which he is adjudged to be liable
for negligence or misconduct in the performance of his duty to the Company
unless a court determines otherwise. The foregoing right to indemnity is not
exclusive of any other right to indemnity which a director or officer may be
entitled under any other agreement or by vote of the Company's shareholders,
directors, or otherwise.

          The XETA Technologies 2000 Stock Option Plan also provides for
indemnification of the members of the committee charged with administering the
Plan. In addition, the Company maintains insurance to protect its officers and
directors from certain liabilities.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

ITEM 9. UNDERTAKINGS.

          The undersigned registrant hereby undertakes to file, during any
period in which offers or sales are being made, a post-effective amendment to
this Registration Statement to include any additional material information on
the plan of distribution or any material change to such information.

          The undersigned registrant hereby further undertakes (i) that, for the
purpose of determining any liability under the Securities Act of 1933, as
amended (the "Securities Act"), it will treat each post-effective amendment as a
new registration statement of the securities offered, and the offering of the
securities at that time, to be the initial bona fide offering thereof; and (ii)
to file a post-effective amendment to remove from registration any of the
securities being registered which remain unsold at the termination of the
offering.

          The undersigned registrant hereby further undertakes that, for
purposes of determining any liability under the Securities Act, each filing of
the registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

          Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

Inc., an Oklahoma corporation (the "Company"), with the Securities and Exchange

ITEM 4. DESCRIPTION OF SECURITIES.

          Not applicable.

ITEM 5. INTERESTS OF NAMED EXPERTS AND COUNSEL.

          The legality of the issuance of the shares of Common Stock offered
hereby has been passed upon for the Company by the firm of Barber & Bartz, a
Professional Corporation, which serves as general counsel to the Company. Ron B.
Barber, senior shareholder of the firm, is a director of the Company and
beneficially owns approximately 1.25% of the Company's outstanding Common Stock.

ITEM 6. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

          The Oklahoma General Corporation Act (the "OGCA") and the Company's
Bylaws each contain provisions for indemnification of officers and directors of
the Company against liability incurred by them under certain circumstances in
their capacities as officers and directors of the Company.

          The OGCA and the Company's Bylaws provide for indemnification of its
officers and directors against expenses (including attorneys' fees, judgments,
fines and amounts paid in settlement) actually and reasonably incurred in
connection with the defense of any threatened, pending or completed legal
proceeding in which the officer or director is a party or threatened to be made
a party by reason of the fact that he is or was a director or officer of the
Company, if he acted in good faith and in a manner that he reasonably believed
to be in, or not opposed to, the best interests of the Company, and, with
respect to any criminal action or proceeding, if he had no reasonable cause to
believe that his conduct was unlawful. If the legal proceeding, however, is by
or in the right of the Company, the director or officer may not be indemnified
in respect of any claim, issue or matter as to which he is adjudged to be liable
for negligence or misconduct in the performance of his duty to the Company
unless a court determines otherwise. The foregoing right to indemnity is not
exclusive of any other right to indemnity which a director or officer may be
entitled under any other agreement or by vote of the Company's shareholders,
directors, or otherwise.

          The XETA Technologies 2000 Stock Option Plan also provides for
indemnification of the members of the committee charged with administering the
Plan. In addition, the Company maintains insurance to protect its officers and
directors from certain liabilities.

ITEM 7. EXEMPTION FROM REGISTRATION CLAIMED.

          Not applicable.

ITEM 9. UNDERTAKINGS.

          The undersigned registrant hereby undertakes to file, during any
period in which offers or sales are being made, a post-effective amendment to
this Registration Statement to include any additional material information on
the plan of distribution or any material change to such information.

          The undersigned registrant hereby further undertakes (i) that, for the
purpose of determining any liability under the Securities Act of 1933, as
amended (the "Securities Act"), it will treat each post-effective amendment as a
new registration statement of the securities offered, and the offering of the
securities at that time, to be the initial bona fide offering thereof; and (ii)
to file a post-effective amendment to remove from registration any of the
securities being registered which remain unsold at the termination of the
offering.

          The undersigned registrant hereby further undertakes that, for
purposes of determining any liability under the Securities Act, each filing of
the registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

          Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the registrant of expenses
incurred or paid by a director, officer or controlling person of the registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

Registration Statement to be signed on its behalf by the undersigned, thereunto
