Item 2.    SALE OF INTEREST IN TALON TECHNOLOGY

     On December 20, 2001 Ultradata completed the sale of its interest in
Navman NZ Limited, which was formerly known as "Talon Technology Limited."
Ultradata transferred the Talon shares to Emerald Capital Partners Limited.
In exchange for the Talon shares, Ultradata received $930,000 cash and two
promissory notes.

     The promissory notes, identical but for the signer, were made by Peter
Maire and Lionel Rogers, who are principals of Navman.  Each note provides for
the payment to Ultradata of $150,000 plus accrued interest, if any.  No
interest will accrue on the notes until December 12, 2004.  From December 12,
2004 through December 11, 2006 interest will accrue at a rate of five percent
per annum.  The notes are payable on the earlier of (a) December 11, 2006 (on
which date $165,000 would be payable) or (b) the date on which the signer
sells twenty percent of his Navman shares or (c) the date on which Navman is
acquired by or merged into another entity, or (d) the date on which Navman
sells equity to the public.

Item 5.    AMENDMENT TO CONVERTIBLE NOTES AND WARRANTS

     On December 11, 2001 Ultradata entered into an Agreement with the two
institutions which are holders of its 11.25% Senior Subordinated Secured
Convertible Promissory Notes (the "Notes") and of Warrants to purchase 478,506
shares of Ultradata Common Stock (the "Warrants").  The Agreement provided
that the $930,000 cash payment that Ultradata has received from the sale of
its Talon shares would be paid directly to the holders of the Notes to reduce
Ultradata's liability under the Notes.  The Agreement also amended the terms
of the Notes as follows:

     1. The 10% special interest payment that would have been due on the
	outstanding balance of the Notes at June 1, 2002 has been waived.

     2. The required monthly payment on account of the Notes has been
	reduced from $90,000 to $15,000.

     3. The total number of shares into which the Notes may be converted
	during any 90 day period has been increased to 28% (previously 20%)
	of the cumulative trading volume for the 66 trading days preceding
	the date of conversion.

     4. Ultradata will no longer be required to maintain an effective regis
	tration statement covering the shares into which the Notes are
	convertible, provided that Ultradata is not in default under the
	Notes.

     In addition, the Agreement reduced the exercise price of the Warrants
from $1.50 to $.50 per share.

				 AMENDMENT
				   TO THE
		     11.25% SENIOR SUBORDINATED SECURED
			CONVERTIBLE PROMISSORY NOTES
				    AND
				 WARRANTS
		     OF ULTRADATA SYSTEMS, INCORPORATED

     THIS AMENDMENT TO 11.25% SENIOR SUBORDINATED SECURED CONVERTIBLE
PROMISSORY NOTES AND WARRANTS OF ULTRADATA SYSTEMS, INCORPORATED is entered
into effective as of the 11th day of December 2001 (the "Amendment") by and
among the undersigned holders (each a "Holder" and together the "Holders") and
Ultradata Systems, Incorporated, a Delaware corporation (the "Company").

     WHEREAS, the parties entered into that certain Exchange Agreement dated
August 13, 2001 (as amended, the "Exchange Agreement"), pursuant to which the
Company issued and sold to the Holders 11.25% Senior Subordinated Secured
Convertible Promissory Notes in the aggregate original principal amount of
$1,748,120 (the "Notes") and warrants (the "Warrants") in exchange for 1,408
shares of the Company's Series A Preferred Stock held by the Holders; and

     WHEREAS, the Company is currently in default under the Notes.

     WHEREAS, the current principal balance outstanding under the Notes on the
date hereof is $1,565,810 and the current accrued interest through the date
hereof is $30,205.

     WHEREAS, the Company plans to sell its equity interest in a New Zealand
based company called Navman NZ Limited, formerly called Talon Technology
Limited ("Navman"), for total consideration of US$930,000 (the "Purchase
Price").

     WHEREAS, in consideration for the Company's payment of the entire Purchase
Price to the Holders to pay down a portion of the balance due thereunder, and
for other consideration set forth herein, the Holders are willing to amend the
terms of the Notes as set forth herein.

     NOW, THEREFORE, in consideration of the mutual promises, representations,
warranties, covenants and conditions set forth in this Amendment, the parties
hereto agree as follows:

     1. Defined Terms.  Terms that are used herein with initial capital
letters and are not otherwise defined herein will have the meanings given to
them in the Exchange Agreement and the Notes.

     2. Payment on the Notes.  Effective immediately upon the closing of the
Company's sale of its equity interest in Navman, the Company agrees to pay the
entire Purchase Price to the Holders in partial payment of the Notes by
instructing the purchasers to direct the Escrow Agent to wire such funds
directly to an account designated by the Holders.  The Holders waive the
prepayment penalty prescribed in the Notes with respect to this payment.

     3. Waiver of Default and Amendments to the Notes. Effective upon the
Company's payment to the Holders as provided in Section 2 above and Holders'
receipt thereof on or before December 20, 2001 (the "Closing"), the Holders
agree not to pursue foreclosure based on any and all defaults with respect to
the Notes that exist on such date, and the Notes shall thereafter be amended
as follows:

	(a)  Waiver of Special Interest Payment.  The Holders agree to waive
the 10% interest payment due and payable under the Notes on June 1, 2002.

	(b)  Reduction to Monthly Installment Amount.  The equal monthly
installments of principal and interest due and payable under the Notes shall
be reduced from $90,000 to $15,000, and the Company agrees to consider in good
faith any requests by the Holders for future modifications to that monthly
payment amount.  The aggregate principal balance due under the Notes is not
affected by this reduction in the monthly installment amount.

	(c)  Increase in Conversion Cap.  The Conversion Cap, as defined in
Section 3(i) of the Notes, shall be increased from 20% to 28% of the cumulative
trading volume of the Company's Common Stock for the period indicated therein.

     4. Amendment to the Warrants.  Effective upon the Closing, the Company
agrees to reduce the per share exercise price of the Warrants from $1.50 to
