                   BARRY E. REIFLER'S EMPLOYMENT ARRANGEMENT


The following represents the agreement in principle between Barry E. Reifler
and MicroTel International, Inc., which is to be memorialized in a definitive
agreement(s) as soon as possible hereafter.

1)       Barry's EMPLOYMENT AGREEMENT dated February 9, 1996, as amended on
         August 15, 1996 (the "Amended Agreement"), will remain in full force
         and effect as amended by this letter agreement, with the proviso that
         he has up to 3 months after the consummation of the merger with XIT
         Corporation (the "Merger") in which to make a determination as to
         whether he deems the change in control to be an adverse change in
         employment circumstances.
2)       Barry will serve MicroTel International, Inc. as its Chief Financial
         Officer under the same conditions and terms of the Amended Agreement
         with the following amendments and understandings:
         a)      Base compensation will be increased to $150,000 per year
                 effective with the date of the Merger.
         b)      The severance provisions will be amended to provide the
                 benefits provided for in paragraph 15 of the Amended Agreement
                 as if he had triggered the provision immediately upon the
                 change in control (i.e. based on an annual salary of $125,000
                 and covering his current equity position prior to this new
                 employment arrangement).
         c)      Although no contractual revision is necessary regarding the
                 following, it is expressly understood that expenses will be
                 paid for or reimbursed explicitly for items of the same nature
                 as were provided during Barry's tenure as CFO pre-merger when
                 corporate headquarters were located in San Jose, CA.,
                 including (by way of illustration and not limited to) a
                 corporate apartment and operating costs of his personal
                 vehicle located in California used for travel while at
                 corporate headquarters.
3)       Barry will receive a signing bonus of non-qualified options to acquire
         150,000 shares of common stock of MicroTel International, Inc.  at an
         exercise price $2.375 per share.  The options will be issued pursuant
         to the Company's S-8, if amended to be used for resale purposes, or
         the underlying shares will be accorded piggyback registration rights.
         The options will vest ratably on a monthly basis over a six (6) month
         period beginning six (6) months and one day after the effective date
         of the merger, will be exercisable for a period of 3 years, and those
         vested will survive termination.

Attached are the Employment Agreement dated February 9, 1996 and Amendment No.
1 thereto dated August 15, 1996 for reference.
