PART III -— NARRATIVE

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

As reported in a press release dated September 26, 2006, the corporation announced that it filed its amended 2004 annual report on Form 10-K/A with the Securities and Exchange Commission. The amended 2004 Form 10-K/A included restated financial statements for the fiscal years ended 2002-2004 that reflect changes primarily as a result of First Bancorp’s previously-reported audit committee review of the accounting treatment of certain mortgage-related transactions and pass-through trust certificates and of interest rate swaps that hedge the interest rate risk related to the fixed interest rate mainly on the corporation’s outstanding brokered certificates of deposit and certain medium-term notes. First Bancorp is currently in the process of preparing its 2005 annual report on Form 10-K. As soon as the 2005 Form 10-K has been filed; the corporation expects to begin preparing its quarterly reports on Form 10-Q. First Bancorp expects to file the annual report on Form 10-K for the year ended December 31, 2005 during the first quarter of 2007. Thereafter, it expects to file the appropriate quarterly reports, including the quarterly report on Form 10-Q for the quarter ended September 30, 2006.

PART IV —OTHER INFORMATION

(1)

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

Fernando Scherrer		(787)		729-8098
(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 file? If answer is no, identify report(s). Yes   o     No   x
		The corporation's Quarterly Reports on Form 10-Q for the periods ended June 30, 2005, September 30, 2005, March 31, 2006, June 30, 2006 and September 30, 2006 and the corporations Annual Report on Form 10-K for the fiscal year ended December 31, 2005 have not been filed.
(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? Yes   o     No   x
		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 corporation has not filed its quarterly financial statements for the quarter ended September 30, 2005 yet because it finished preparing restated financial statements for the fiscal years ended 2002-2004 on September 26, 2006. Therefore, the corporation does not know now whether the results for the quarter ended September 30, 2006 will significantly differ from the corresponding 2005 quarter. In light of the requirement to mark to market the interest rate swaps that hedge the interest rate risk related to certain of the corporation's liabilities in the period ended September 30, 2005 but not in the 2006 period because of the corporation's adoption of the long-haul method of accounting for most of the interest rate swaps during April 2006, the results for the 2006 period may differ significantly from the 2005 period.
