                                 FORM 12b-25 OF
                            NETFABRIC HOLDINGS, INC.


      With respect to the Form 10-KSB for the year ended December 31, 2005


On May 20, 2005, the Registrant entered into and closed on a share exchange
agreement, whereby the Registrant acquired all of the issued and outstanding
shares of UCA Services, Inc. Therefore, the results of operations for the fiscal
year ended December 31, 2005 will significantly vary from the corresponding
period of the prior fiscal year. The audit of the Company's financial statements
could not be completed in a timely manner. Until the audit is complete, a
reasonable estimate of the results cannot be made.
