                                    PART III
                                    NARRATIVE

     State below in reasonable detail the reasons why Form 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.

     As disclosed in a press release issued by Oriental Financial Group Inc.
(the "Group") on March 15, 2006, the Group was unable to file its report on Form
10-K for the six-month transition period ended December 31, 2005, which was due
March 16, 2006.

     The reason for the delay is that the Group is reevaluating the accounting
treatment given in previously reported financial statements to the following
matters: (i) certain mortgage loan purchases recorded in the first and third
quarters of the fiscal year ended June 30, 2005, and (ii) certain employee stock
option awards.

     The mortgage-related transactions are reflected in the Group's previously
issued financial statements as purchases of residential mortgage loans secured
by first mortgages. If the Group concludes that such transactions do not qualify
as purchases for accounting purposes, said transactions, with an outstanding
loan principal balance of approximately $85 million, will be accounted for as
commercial loans secured by first mortgages. The Group anticipates that any
revised classification of these mortgage-related transactions will not result in
the need for additional reserves or the need to adjust stockholders' equity, net
earnings or earnings per share for any period. Management also expects that any
revised classification would not have a significant impact on its compliance
with the regulatory capital requirements and that, if required, it would obtain
a waiver from the Office of the Commissioner of Financial Institutions of Puerto
Rico with respect to the statutory limit for individual borrowers.

     The review of the employee stock option awards pertains to the accounting
treatment of certain non-traditional antidilution provisions in the employment
contracts of various officers that may result in some of these awards to be
treated as variable awards as opposed to fixed awards. This may require an
adjustment to the stockholders' equity as of September 30, 2005, June 30, 2005
and the results of operations for the quarter and year then ended, respectively,
and other previously reported periods. It is expected, however, that the net
effect of such adjustments at September 30, 2005, would reverse in the
subsequent quarter and therefore would not impact total stockholders' equity at
December 31, 2005.

                                     PART IV
                                OTHER INFORMATION

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


                                                       
Mr. Jose Rafael Fernandez                (787)               771-6800, Ext. 6169
          (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 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 reasons why a reasonable
estimate of the results cannot be made.

     Please refer to the narrative explanation provided in the last paragraph
of Part III hereof. Given that the review of this matter by the Group and the
Audit Committee of its Board of Directors has not concluded, the Group cannot
provide at this time a reasonable estimate of such results.
