EXHIBIT 10.17

                    First Amendment to Employment Agreement

     First Amendment to Employment Agreement, dated as of May 31, 2001 ("First
Amendment"), between Brent A. Straka (the "Executive") and Eagle Point Software
Corporation (the "Company").

     Whereas, the Executive and the Company have entered in an Employment
Agreement dated as of January 2, 2001 (the "Agreement") providing, among other
things, for the terms and conditions upon which the Company shall employ the
Executive; and

     Whereas, each of the Executive and the Company desire to amend and
supplement the Agreement in certain respects as described in this First
Amendment.

     Now, therefore, in consideration of the premises and the covenants and
agreements hereinafter set forth, the parties agree as follows:

     1.   Notwithstanding anything contained in the Agreement to the contrary,
if an event constituting Good Reason (as defined below) shall have occurred and
be continuing, the Executive shall be permitted to terminate the Agreement upon
ten business days' written notice to the Company and shall be entitled to
receive such payments and other benefits determined in accordance with Section
4(d) of the Agreement as opposed to Section 4(e) of the Agreement.

     2.   As used in this First Amendment, "Good Reason" means, without the
Executive's express written consent, the occurrence of any of the following
events:

(22) any of (i) the assignment to the Executive of any duties inconsistent in
  any material respect with the Executive's position(s), duties,
  responsibilities or status with the Company as contemplated by the Agreement,
  (ii) a change in the Executive's reporting responsibilities, titles or offices
  with the Company as contemplated by the Agreement or (iii) any removal or
  involuntary termination of the Executive from the Company otherwise than as
  expressly permitted by the Agreement;

(23) a reduction by the Company in the Executive's rate of annual base salary or
  the Executive's target total annual compensation;

(24) the establishment by the Company of performance goals and similar criteria
  as a condition to the receipt by the Executive of variable compensation that
  are less favorable to the Executive than those established for other
  executives of the Company;

(25) the failure of the Company to provide the Executive with benefits that are,
  in the aggregate, at least as favorable to him as are provided to him as of
  the date hereof;

(26) any requirement of the Company that the Executive be based anywhere other
  than at the Company's facility in Dubuque, Iowa;

(27) the failure of the Company to (i) permit the Executive to participate in
  the Company's employee benefit plans generally available to executives of the
  Company, (ii) permit the Executive to take time off for vacation or illness in
  accordance with the Company's policy for executives or (iii) provide to the
  Executive all other fringe benefits as are from time to time made generally
  available to executives of the Company; or

(28) the failure of the Company to comply with its obligations under the
  Agreement;

                                     -74-
<PAGE>

Provided, however, that an isolated, insubstantial and inadvertent action taken
in good faith and which is remedied by the Company promptly after receipt of
notice thereof given by the Executive shall not constitute Good Reason.

     3.   Section 4(d)(ii) of the Agreement is amended by replacing the phrase
"at any time before January 1, 2002" with the phrase "at any time on or before
January 1, 2002".

     4.   Except as expressly modified hereby, the Agreement remains in full
force and effect. Upon the execution and delivery hereof, the Agreement shall
thereupon be deemed to be amended and supplemented as hereinabove set forth as
fully and with the same effect as if the amendments and supplements made hereby
were originally set forth in the Agreement, and this First Amendment and the
Agreement shall henceforth be read, taken and construed as one and the same
instrument, but such amendments and supplements shall not operate so as to
render invalid or improper any action heretofore taken under the Agreement.

     5.   This First Amendment may be executed in two counterparts, each of
which shall be deemed to be an original and both of which together shall
constitute one and the same instrument.

     In Witness Whereof, the parties hereto have executed this First Amendment
as of the date first written above.

                      SECOND AMENDMENT TO CREDIT AGREEMENT

         THIS SECOND AMENDMENT TO CREDIT AGREEMENT ("Amendment") is made and
entered into as of June 8, 2001 (the "Amendment Date"), by and among XETA
Technologies, Inc., an Oklahoma corporation, formerly known as Xeta Corporation
(the "Borrower"), Bank One, Oklahoma NA, and First Star Bank, N.A., formerly
known as Mercantile Bank, N.A., as Lenders under the Credit Agreement referred
to below (the "Lenders"), and Bank One, Oklahoma, NA, as Agent (in such
capacity, the "Agent"), with reference to the following:

         A. The Borrower, the Lenders, the Agent and Banc One Capital Markets,
Inc., as Lead Arranger and Sole Book Runner, are parties to that certain Credit
Agreement dated as of November 30, 1999, as amended by that certain First
Amendment to Credit Agreement dated as of August 21, 2000 (the "Credit
Agreement"), pursuant to which the Lenders severally agreed to make Loans to the
Borrower under three (3) Credit Facilities therein described.

         B. Subject to the terms and conditions set forth in this Amendment, the
Borrower and the Lenders have agreed to: (i) reduce the remaining availability
under the Acquisition Facility to $1,000,000, and (ii) modify the Applicable
Margin until such time as the Borrower achieves compliance with covenants
governing the Debt Service Coverage Ratio.

         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. REDUCTION IN ACQUISITION LOAN FACILITY. Under the Credit Agreement, the
Aggregate Acquisition Loan Commitment was originally $12,000,000. The Borrower
acknowledges and agrees that as of the Amendment Date: (i) the outstanding
principal balance under the Acquisition Loan Facility is $7,668,389.10, and (ii)
neither the Borrower nor any Guarantor has any defenses to payment, offsets,
recoupments, deductions, or counterclaims with respect to the Acquisition Note
or any Acquisition Term Note. The Borrower and the Lenders hereby reduce the
remaining availability under the Acquisition Loan Facility from $3,479,567.70 to
$1,000,000.

3. CHANGE IN APPLICABLE MARGIN. The parties have agreed to modify the Applicable
Margin to provide an increase in both the Eurodollar Rate and the Floating Rate
until such time as the Borrower, as of the end of its fiscal quarter, has
achieved a Debt Service Coverage Ratio, as calculated under Section 6.24.2 of
the Credit Agreement, of at least 1.20:1. In order to effectuate the foregoing,
the parties agree that until such time as the Borrower, as of the end of its
fiscal quarter, has achieved a Debt Service Coverage Ratio, as calculated under
Section 6.24.2 of the Credit Agreement, of at least 1.20:1, the Applicable
Margin shall be

<PAGE>   2

determined with reference to the attached "Temporary Debt Service Pricing
Schedule," during which time, the term "Pricing Schedule" as used in the Credit
Agreement shall mean and refer to the Temporary Debt Service Pricing Schedule
attached to this Second Amendment identified as such. Once the Borrower has
achieved the referenced Debt Service Coverage Ratio, the Applicable Margin shall
thereafter be calculated with reference to the Pricing Schedule attached to the
Credit Agreement and the term "Pricing Schedule" as used in the Credit Agreement
shall thereafter mean and refer to the Pricing Schedule attached to the Credit
Agreement identified as such.

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):

         C. Accuracy of Representations and Warranties. All representations and
warranties made by the Borrower in the Credit Agreement and the other Loan

Borrower refer to an earlier specified date).

         D. No Default. There shall not have occurred any Default or Unmatured

a Material Adverse Effect.

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.

         For the purposes of this Temporary Debt Service Pricing Schedule, the
following terms have the following meanings, subject to the final paragraph of
this Temporary Debt Service Pricing Schedule:

         "Financials" means the annual or quarterly financial statements of the
Borrower delivered pursuant to Section 6.1(i) or (ii).

         "Level I Status" exists at any date if, as of the last day of the
fiscal quarter of the Borrower referred to in the most recent Financials, the
Leverage Ratio is less than or equal to 1.0 to 1.00.

         "Level II Status" exists at any date if, as of the last day of the
fiscal quarter of the Borrower referred to in the most recent Financials, (i)
the Borrower has not qualified for Level I Status and (ii) the Leverage Ratio is
less than or equal to 1.5 to 1.00.

         "Level III Status" exists at any date if, as of the last day of the
fiscal quarter of the Borrower referred to in the most recent Financials, (i)
the Borrower has not qualified for Level I Status or Level II Status and (ii)
the Leverage Ratio is less than or equal to 2.0 to 1.00.

         "Level IV Status" exists at any date if, as of the last day of the
fiscal quarter of the Borrower referred to in the most recent Financials, (i)
the Borrower has not qualified for Level I Status, Level II Status or Level III
Status and (ii) the Leverage Ratio is less than or equal to 2.5 to 1.00.

         "Level V Status" exists at any date if the Borrower has not qualified
for Level I Status, Level II Status, Level III Status or Level IV Status.

         "Status" means either Level I Status, Level II Status, Level III
Status, Level IV Status or Level V Status.

         The Applicable Margin and Applicable Fee Rate shall be determined in
accordance with the foregoing table based on the Borrower's Status as reflected
in the then most recent Financials, until the Borrower's Debt Service Coverage
Ratio, as provided for and calculated under Section 6.24.2 of the Credit
Agreement, is equal to or in excess of 1.20:1 as of the last day of the fiscal
quarter of the Borrower referred to in the most recent Financials at which time
the Applicable Margin and Applicable Fee Rate shall be determined in accordance
with the "Pricing Schedule" attached to the Credit Agreement and identified as
such. Adjustments, if any, to the Applicable Margin or Applicable Fee Rate shall
be effective five Business Days after the Agent has received the applicable
Financials. If the Borrower fails to deliver the Financials to the Agent at the
time required pursuant to Section 6.1, then the Applicable Margin and Applicable
Fee Rate shall be the highest Applicable Margin and Applicable Fee Rate set
forth in the foregoing table until five days after such Financials are so
delivered.
