                                    NARRATIVE


      State below in reasonable detail the reasons why Form 10-K, 11-K, 20-F,

the prescribed time period.

      The Company's Annual Report on Form 10-KSB for the period ended October
31, 2006 cannot be filed within the prescribed time period because the Company
requires additional time for compilation and review to insure adequate
disclosure of certain information required to be included in the Form 10-QKSB.
The Company's Annual Report on Form 10-KSB will be filed on or before the 15th
calendar day following the prescribed due date.

                                     PART IV

                                OTHER INFORMATION

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

            Manuel O. Morera, Chief Financial Officer, 787-278-2709.

      (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 the 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
            reason why a reasonable estimate of the results cannot be made.

            Prior to January 25, 2006, the registrant, then named Lawrence
            Consulting Group, Inc., was a shell corporation which was engaged in
            limited consulting activities. On January 25, 2006, the registrant
            acquired Plaza Consulting Group, Inc. in a transaction which is
            accounted for as a reverse acquisition. As a result, the results of
            operations for periods prior to January 35, 2006 will be the results
            of operations of Plaza Consulting Group, which is the accounting
            acquirer.

            Based on preliminary financial statements, the registrant will show
            net income of approximately $2.3 million on revenues of
            approximately $14.2 million for the year ended October 31, 2006,
            compared with net income of approximately $6.4 million on revenues
            of approximately $17.4 million for the year ended October 31, 2005.
