                       PART II -- RULES 12B-25(B) AND (C)


If the subject report could not be filed without unreasonable effort or expense
and the registrant seeks relief pursuant to Rule 12b-25(b), the following should
be completed. (Check box if appropriate)

      (a)   The reason described in reasonable detail in Part III of this form
            could not be eliminated without unreasonable effort or expense;

      (b)   The subject annual report, semi-annual report, transition report on
            Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or
 |X|        portion thereof, will be filed on or before the fifteenth calendar
            day following the prescribed due date; or the subject quarterly
            report or transition report on Form 10-Q or subject distribution
            report on Form 10-D, or portion thereof, will be filed on or before
            the fifth calendar day following the prescribed due date; and

      (c)   The accountant's statement or other exhibit required by Rule
            12b-25(c) has been attached if applicable.


                              PART III -- NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR,
N-CSR, or the transition report or portion thereof, could not be filed within
the prescribed time period.

The Annual Report of the Registrant on Form 10-KSB for the fiscal year ended
December 31, 2005 (the "Form 10-KSB") could not be filed on a timely basis
because management requires additional time to compile and verify the data
required to be included in the Form 10-KSB. The Form 10-KSB will be filed within
fifteen calendar days of the date the original report was due.


                          PART IV -- OTHER INFORMATION

(1)   Name and telephone number of person to contact in regard to this
      notification

           MICHAEL MEYER          (408)                       956-8000
           -------------          -----                       --------
              (Name)           (Area Code)               (Telephone Number)

(2)   Have all other periodic reports required under Section 13 or 15(d) of the
      Securities Exchange Act of 1934 or Section 30 of the Investment Company
      Act of 1940 during the preceding 12 months or for such shorter period that
      the registrant was required to file such report(s) been filed? If answer
      is no, identify report(s).

      |X| Yes |_| No

(3)   Is it anticipated that any significant change in results of operations
      from the corresponding period for the last fiscal year will be reflected
      by the earnings statements to be included in the subject report or portion
      thereof?

      |X| Yes |_| No

      If so, attach an explanation of the anticipated change, both narratively
      and quantitatively, and, if appropriate, state the reasons why a
      reasonable estimate of the results cannot be made.





      The results of operations for the fiscal year ended December 31, 2005 will
      represent a significant change from the results of operations from the
      corresponding period for the last fiscal year. The results of operations
      for the twelve months ended December 31, 2004 represent the financial
      results for Rescon Technology Corporation ("Rescon"), the predecessor of
      Nayna Networks, Inc. ("Nayna"). The results of operations for the current
      fiscal year ended December 31, 2005 represent the results of operations
      for Nayna, which was acquired by Rescon on April 1, 2005. Due to the
      different nature of the businesses conducted by Rescon and Nayna, the
      Registrant anticipates that the results of operations for the two
      corresponding periods will differ significantly.

                              NAYNA NETWORKS, INC.
