         This Guaranty (the "Guaranty") is made and entered into as of November
4, 1998, (the "Effective Date"), by National Telephone & Communications, Inc., a
Delaware corporation ("Guarantor"), in favor of Ironwood Telecom LLC, a Colorado

secured by the Loan and Security Agreement dated as of the Effective Date (the
"Loan Agreement") given to Lender by Incomnet, Inc., a California corporation
("Borrower").  The Bridge Loan Note, Guaranty, and Loan Agreement are
collectively referred to as the Loan Documents.

Guarantor, for the benefit of Lender, agrees as set forth below.

1.      DEFINITIONS.

         Any capitalized term not otherwise defined in this Guaranty shall have
the meaning given to the term in the Loan Agreement.

2.      GUARANTY.

         Guarantor unconditionally guaranties to Lender the timely (whether as
scheduled or upon acceleration) payment and performance by Borrower of the
following (the "Guarantied Obligations"):

         2.1.  The principal, interest and other charges or amounts
due under the Bridge Loan Note and the other Loan Documents (whether by
acceleration or otherwise) and all renewals, extensions, modifications and
rearrangements of any of the Loan Documents;

         2.2.  The other obligations set forth in or arising out of
the Bridge Loan Note and the other Loan Documents;

         2.3.  Any of the forgoing arising out of or in connection
with any renewal, extension or other modification of the Bridge Loan Note or any
of the other Loan Documents;

         2.4.  Any of the foregoing arising after Borrower has
commenced or become subject to any proceeding under the Bankruptcy Code,
including any advances made to Borrower, any interest that accrues after the
filing of the bankruptcy petition (even if the interest cannot be collected in
the proceeding under the Bankruptcy Code), and attorneys fees.

If Borrower fails to pay or perform any of the Guarantied Obligations, Guarantor
will immediately pay or perform the obligation upon the written request of the
Lender.

                           have.

         3.3.    In the event Borrower becomes subject to a voluntary or
                  involuntary proceeding under the Bankruptcy Code, Lender may
