                             SUMMARY FINANCIAL DATA
 
     You should read the summary financial information presented below together
with First BanCorp's consolidated financial statements and notes which are
incorporated by reference into this prospectus and with the historical financial
information of First BanCorp included under "Selected Financial Data" beginning
on page 10 of this prospectus.
 
     Net income for the year ended December 31, 1996 reflects a one-time
industry-wide deposit insurance assessment of the FDIC's Savings Association
Insurance Fund of $9,115,000 before tax. Excluding this unusual item, net income
for the year ended December 31, 1996 would have amounted to $44,348,791 or $1.44
per share. Net income for the year ended December 31, 1994 reflects an
extraordinary loss net of the estimated tax of $428,874 due to the early
cancellation of $50.0 million in notes payable that were repurchased from the
FDIC. Excluding this extraordinary loss, net income for the year ended December
31, 1994 would have amounted to $30,984,831 or $1.01 per share.
 
     The return on average assets ratio is computed by dividing net income by
average total assets for the period. The return on average equity ratio is
computed by dividing net income by average stockholders' equity for the period.
Both ratios have been computed using daily averages.

            CONSOLIDATED RATIO OF EARNINGS TO COMBINED FIXED CHARGES
                         AND PREFERRED STOCK DIVIDENDS
 
     The ratios shown below measure First BanCorp's ability to generate
sufficient earnings to pay the fixed charges or expenses of its debt. First
BanCorp had no outstanding preferred stock during any of the periods covered by
the ratios shown below. The ratios of earnings to combined fixed charges were
computed by dividing earnings by combined fixed charges and expenses of its
debt.

     For purposes of computing the consolidated ratios of earnings to combined
fixed charges, earnings consist of pre-tax income from continuing operations
plus fixed charges and amortization of capitalized interest, less interest
capitalized. Fixed charges consist of interest expensed and capitalized,
amortization of debt issuance costs, and First BanCorp's estimate of the
interest component of rental expense. Ratios are presented both including and
excluding interest on deposits.

                                  RISK FACTORS
 
     You should carefully consider the following factors and other information
in this prospectus, including the information incorporated by reference in this
prospectus, before deciding to invest in the Series A Preferred Stock.
 
DIVIDENDS WILL NOT BE PAID UNLESS DECLARED BY THE BOARD OF DIRECTORS
 
     Monthly dividends will only be paid if declared by First BanCorp's board of
directors. The board of directors is not obligated or required to declare
monthly dividends.
 
MISSED DIVIDENDS NEVER HAVE TO BE PAID
 
     If the board of directors does not declare a dividend for a particular
month, those dividends never have to be paid.
 
BANKING REGULATIONS MAY RESTRICT FIRST BANCORP'S ABILITY TO PAY DIVIDENDS
 
     First BanCorp may not be able to pay dividends in the future if it does not
earn sufficient operational income. Federal Reserve Board policy is that a bank
holding company should pay dividends only out of its current operating earnings.
 
PAYMENT OF DIVIDENDS MAY BE RESTRICTED BY FIRSTBANK'S ABILITY TO PAY DIVIDENDS
TO FIRST BANCORP
 
     Payment of dividends by First BanCorp may be restricted by FirstBank's
ability to pay dividends to First BanCorp. First BanCorp's only present source
of cash flow to pay dividends consists of dividends from FirstBank because First
BanCorp is a bank holding company with no operations of its own. FirstBank's
ability to pay dividends to First BanCorp may be restricted under certain
circumstances by Puerto Rico and Federal banking laws and regulations. In
addition, FirstBank is a party to certain contracts that may prevent it from
paying dividends to First BanCorp if it does not comply with certain terms and
conditions set forth in those contracts. For example, FirstBank issued its
7 5/8% subordinated capital notes due 2005 under an agreement that prohibits it
from paying dividends if the aggregate amount of dividends paid on its capital
stock exceeds certain limits tied to earnings and proceeds from the sale of
capital stock. As of December 31, 1998, FirstBank could have paid up to $110.8
million in dividends under that agreement.
 
INCREASES IN INTEREST RATES MAY NEGATIVELY AFFECT FIRST BANCORP'S PROFITABILITY
 
     Increases in interest rates are the primary market risk affecting First
BanCorp. Interest rates are highly sensitive to many factors, such as
governmental monetary policies and domestic and international economic and
political conditions, that are beyond the control of First BanCorp.
 
     Increases in interest rates may negatively affect the following areas of
First BanCorp's business:
 
     - the net interest income;
     - the value of holdings of securities; and
     - the number of loans originated, particularly mortgage loans.
 
     Increases in Interest Rates May Reduce Net Interest Income.  Increases in
short-term interest rates may reduce net interest income, which is the principal
component of First BanCorp's earnings. Net interest income is the difference
between the amount received by First BanCorp on its interest-earning assets and
the interest paid by First BanCorp on its interest-bearing liabilities. Many of
First BanCorp's assets, like some portions of its loans and its mortgage-backed
securities, are long-term assets with fixed interest rates. In contrast, most of
First BanCorp's liabilities are short-term. When interest rates rise, First
BanCorp must pay more in interest on its liabilities while the interest earned
on its assets does not rise as quickly. This may cause First BanCorp's profits
to decrease.
 
     Increases in Interest Rates May Reduce the Value of First BanCorp's
Holdings of Securities.  Increases in interest rates may reduce the value of
First BanCorp's financial assets and have an adverse impact on its
                                        5
<PAGE>   9
 
earnings and financial condition. First BanCorp owns a substantial portfolio of
mortgage-backed securities and other debt securities with fixed interest rates.
The market value of an obligation with a fixed interest rate generally decreases
when prevailing interest rates rise. A reduction in the value of First BanCorp's
financial assets may also reduce the ability of First BanCorp to record gains
from the sale of its investments and trading.
 
     Increases in Interest Rates May Reduce Demand for Mortgage and Other
Loans.  Higher interest rates increase the cost of mortgage and other loans to
consumers and businesses and may reduce demand for such loans, which hurts First
BanCorp's profits. Reduced demand for mortgage and other loans results in
reduced originations by First BanCorp and lower loan origination income.
 
INCREASES IN PROVISIONS FOR LOAN LOSSES WOULD ADVERSELY AFFECT FIRST BANCORP'S
PROFITABILITY AND FINANCIAL CONDITION
 
     An increase in provisions for loan losses by First BanCorp would have an
adverse effect on First BanCorp's profitability and financial condition. First
BanCorp establishes provisions for loan losses, which lead to reductions in its
income from operations, in order to maintain its allowance for future loan
losses at a level which is deemed appropriate by its management based upon an
assessment of the quality of its loan portfolio. First BanCorp may be forced in
the future, as it has done in recent years, to increase its provisions for loan
losses as a result of various economic and other factors that have led to an
increase in its non-performing assets and actual loan losses.
 
FIRST BANCORP IS EXPOSED TO GREATER RISK BECAUSE ITS BUSINESS IS CONCENTRATED IN
PUERTO RICO
 
     Because substantially all of the various types of loans originated by First
BanCorp are originated in Puerto Rico, First BanCorp is exposed to a greater
risk of delinquency and default on these loans resulting from adverse economic,
political or business developments and natural hazard risks affecting Puerto
Rico. If any such developments or risks adversely affect Puerto Rico, First
BanCorp's profitability may decrease.
 
FIRST BANCORP'S BUSINESS WOULD BE DISRUPTED IF ITS COMPUTER SYSTEMS CANNOT WORK
PROPERLY WITH YEAR 2000 DATA
 
     First BanCorp could experience a significant disruption to its business
operations that could have an adverse effect on its profitability if its
computer systems and the computer systems provided by third party vendors on
which it relies are not able to properly use date calculations in the year 2000.
First BanCorp is taking steps that it believes are adequate to make sure this
does not happen. However, First BanCorp cannot assure you that these efforts
will be completely successful. Problems suffered by providers of basic services,
such as telephone, water, sewer and electricity could also have an adverse
impact on First BanCorp's daily operations. First BanCorp is in the process of
revising its existing business interruption contingency plans to address any
disruptions of these basic services.
 
                           FORWARD-LOOKING STATEMENTS
 
     This prospectus, including information incorporated in this prospectus by
reference, contains certain "forward-looking statements" concerning First
BanCorp's operations, performance and financial condition, including its future
economic performance, plans and objectives and the likelihood of success in

of assumptions and estimates which are subject to significant uncertainties,
many of which are beyond the control of First BanCorp. The words "may," "would,"
"could," "will," "expect," "anticipate," "believe," "intend," "plan," "estimate"
and similar expressions are meant to identify these forward-looking statements.
Actual results may differ materially from those expressed or implied by these

                              RECENT DEVELOPMENTS
 
UNAUDITED FIRST QUARTER RESULTS
 
     On April   , 1999, First BanCorp released its unaudited earnings for the
quarter ended March 31, 1999. First BanCorp reported net income of
$          million or $0.               per diluted share for the quarter ended
March 31, 1999, compared to net income of $12.4 million or $0.42 per diluted
share for the quarter ended March 31, 1998. First BanCorp reported net interest
income of $          million for the quarter ended March 31, 1999, compared to
net interest income of $40.6 million for the quarter ended March 31, 1998.
 
     First BanCorp had consolidated total assets of approximately
$          billion, consolidated total deposits of approximately $
billion and consolidated shareholders' equity of approximately $
million as of March 31, 1999, compared to consolidated total assets of
approximately $3.394 billion, consolidated total deposits of approximately
$1.616 billion and consolidated shareholders' equity of approximately $236.6
million as of March 31, 1998. At December 31, 1998, First BanCorp had
consolidated total assets of approximately $4.017 billion, consolidated total
deposits of approximately $1.775 billion and consolidated shareholders' equity
of approximately $270.4 million.
 
ANNOUNCEMENT OF PROJECT "THE NEXT 50"
 
     On March 25, 1999, First BanCorp announced plans to simplify and streamline
its operations in order to make First BanCorp more efficient, responsive and
convenient in serving its customers. The project, known as "The Next 50," given
the beginning of its next fifty years of business, will be implemented by First
BanCorp during the next 18 months. The project involved the full time
participation of 45 employees and of outside consultants, who generated more
than 500 items of improvement to First BanCorp's operations. Once these items of
improvement are fully implemented by First BanCorp, they are expected to add
approximately $12 million in annualized recurring pre-tax earnings through cost
reductions and revenue enhancements. First BanCorp has estimated that the total
after-tax costs relating to the project will be approximately $2.8 million,
which amount will be recorded by First BanCorp as the required conditions for
accounting purposes enable it to record these costs. It is expected that these
costs will be recorded during the quarter ending June 30, 1999.

                                USE OF PROCEEDS
 
     The net proceeds to First BanCorp after deducting expenses from the sale of
shares of Series A Preferred Stock are estimated at approximately $86,865,000.
If the underwriters' over-allotment option is exercised in full, the net
proceeds are estimated at $99,939,750. First BanCorp intends to use the net
proceeds for general corporate purposes, which may include:
 
     - making capital contributions and loans to its subsidiaries;
 
     - funding possible acquisitions of banking and other financial
       institutions;
 
     - funding possible passive portfolio equity and debt investments in other
       companies as permitted by applicable banking laws and regulations; and
 
     - increasing working capital.
 
     First BanCorp has no current agreements regarding any possible acquisitions
or passive portfolio investments.

                            SELECTED FINANCIAL DATA
 
     The following table shows certain selected consolidated financial and
operating data of First BanCorp on a historical basis for each of the five years
in the period ended December 31, 1998. This information should be read together
with First BanCorp's Consolidated Financial Statements and the related notes
incorporated by reference in this prospectus. First BanCorp has made certain
reclassifications to data for years prior to 1998 to conform to 1998
classifications. Certain amounts shown on a per share basis were recalculated,
when applicable, to retroactively consider the effect of common stock splits.
 
     Net income for the year ended December 31, 1996 reflects a one-time
industry-wide deposit insurance assessment of the FDIC's Savings Association
Insurance Fund of $9,115,000 before tax. Excluding this unusual item, net income
for the year ended December 31, 1996 would have amounted to $44,348,791 or $1.44
per share. Net income for the year ended December 31, 1994 reflects an
extraordinary loss net of the estimated tax of $428,874 due to the early
cancellation of $50.0 million in notes payable that were repurchased from the
FDIC. Excluding this extraordinary loss, net income for the year ended December
31, 1994 would have amounted to $30,984,831 or $1.01 per share.
 
     The return on average assets ratio is computed by dividing net income by
average assets for the period. The return on average equity ratio is computed by
dividing net income by average stockholders' equity for the period. The average
equity to average assets ratio is computed by dividing average assets for the
period by average stockholders' equity. The efficiency ratio is computed by
dividing the amount of other operating expenses by the sum of net interest
income and other income, excluding the gain on sale of investments and trading,
and excluding the gain on sale of a subsidiary that was sold in 1995. All ratios
have been computed using daily averages and on a taxable equivalent basis.

            SUMMARY OF CERTAIN TERMS OF THE SERIES A PREFERRED STOCK
 
     The following summary contains a description of the material terms of the
Series A Preferred Stock. The summary is subject to and qualified in its
entirety by reference to First BanCorp's Certificate of Incorporation and to the
Certificate of Designation creating the Series A Preferred Stock (the
"Certificate of Designation"), copies of which are incorporated by reference as
exhibits to the registration statement of which this prospectus is a part.
 
DIVIDENDS
 
     If declared at the option of First BanCorp's board of directors, holders of
record of the Series A Preferred Stock will be entitled to receive cash
dividends in the amount of $          per share each year, which is equivalent
to      % of the liquidation preference of $25.00 per share. First BanCorp is
not required to declare or pay dividends on the Series A Preferred Stock, even
if it has funds available for the payment of such dividends. Dividends may only
be paid out of funds that are legally available for this purpose.
 
     Dividends on the Series A Preferred Stock will accrue from its date of
original issuance and will be payable on the last day of each month in United
States dollars beginning on           , 1999. Payment of dividends will be made
to the holders of record of the Series A Preferred Stock as they appear on the
books of First BanCorp on the second Business Day immediately preceding the
relevant date of payment. In the case of the dividend payable on           ,
1999, this dividend will cover the period from the date of issuance of the
Series A Preferred Stock to           , 1999. If any date on which dividends are
payable is not a Business Day, then payment of the dividend will be made on the
next Business Day without any interest or other payment in respect of the delay.
If December 31 of any year is not a Business Day, then the dividend payable on
such date will be made on the immediately preceding Business Day. A "Business
Day" is a day other than a Saturday or Sunday or a general banking holiday in
San Juan, Puerto Rico or New York, New York.
 
     Dividends on the Series A Preferred Stock will be noncumulative. If the
board of directors does not declare a dividend for any monthly dividend period
on the Series A Preferred Stock, then the holders of Series A Preferred Stock
will not have a right to receive a dividend for that monthly dividend period,
whether or not dividends on the Series A Preferred Stock are declared for any
future monthly dividend period.
 
     Dividends for any monthly dividend period will be paid in equal
installments in the amount of $0.     per share. The aggregate payment made to
each holder will be rounded to the next lowest cent. The amount of dividends
payable for any period shorter than a full monthly dividend period will be
computed on the basis of the actual number of days elapsed in that period.
 
     Dividend payments will be mailed to the record holders of the Series A
Preferred Stock at their addresses appearing on the register for the Series A
Preferred Stock.
 
     The terms of the Series A Preferred Stock do not permit First BanCorp to
declare, set apart or pay any dividend or make any other distribution of assets
on, or redeem, purchase, set apart or otherwise acquire shares of common stock
or of any other class of stock of First BanCorp ranking junior to the Series A
Preferred Stock as to the payment of dividends or as to the distribution of
assets upon liquidation, dissolution or winding up of First BanCorp, unless
certain conditions are met. Those conditions are (1) all accrued and unpaid
dividends on the Series A Preferred Stock for the twelve monthly dividend
periods ending on the immediately preceding dividend payment date shall have
been paid or are paid contemporaneously, (2) the full monthly dividend on the
Series A Preferred Stock for the then current month has been or is
contemporaneously declared and paid or declared and set apart for payment, and
(3) First BanCorp has not defaulted in the payment of the redemption price of
any shares of Series A Preferred Stock called for redemption. See "Redemption at
the Option of First BanCorp." The above limitations do not apply to stock
dividends or other distributions made in stock of First BanCorp ranking junior
to the Series A Preferred Stock as to the payment of dividends and as to the
distribution of assets. The above limitations also do not apply to conversions
or exchanges for stock of First BanCorp ranking junior to the Series A Preferred
Stock as to the payment of dividends and as to the distribution of assets.

<PAGE>   16
 
     If First BanCorp is unable to pay in full the dividends on the Series A
Preferred Stock and on any other shares of stock of equal rank as to the payment
of dividends with the Series A Preferred Stock, all dividends declared upon the
Series A Preferred Stock and any such other shares of stock will be declared pro
rata. In this event, each share of Series A Preferred Stock and of the other
classes of stock of equal rank will receive dividends in the same proportion as
the $25.00 per share liquidation preference of the Series A Preferred Stock
bears to the per share liquidation preference of the other classes of equally
ranked stock.
 
     For a discussion of the tax treatment of distributions to stockholders see
"Taxation," "Puerto Rico Taxation," and "United States Taxation."
 
NO CONVERSION OR EXCHANGE RIGHTS
 
     The Series A Preferred Stock will not be convertible into or exchangeable
for any other securities of First BanCorp.
 
REDEMPTION AT THE OPTION OF FIRST BANCORP
 
     First BanCorp may not redeem the shares of the Series A Preferred Stock
prior to           , 2004. On and after that date, First BanCorp may redeem the
Series A Preferred Stock for cash, at its option, in whole or in part, at the
redemption prices shown below plus accrued and unpaid dividends for the then
current monthly dividend period to the redemption date. The redemption prices
for the twelve month periods beginning on             , 2004 are shown below.

</TABLE>
 
     In the event that First BanCorp elects to redeem less than all of the
outstanding shares of the Series A Preferred Stock, the shares to be redeemed
will be allocated pro rata or by lot as may be determined by the board of
directors, or by any other method as the board of directors may consider fair.
Any method chosen by First BanCorp will conform to any rule or regulation of any
national or regional stock exchange or automated quotation system on which the
shares of the Series A Preferred Stock may at the time be listed or eligible for
quotation.
 
     First BanCorp will mail a notice of any proposed redemption to the holders
of record of the shares of Series A Preferred Stock to be redeemed, at their
address of record, not less than 30 nor more than 60 days prior to the
redemption date. The notice of redemption to each holder of shares of Series A
Preferred Stock will specify the number of shares of Series A Preferred Stock to
be redeemed, the redemption date and the redemption price payable to the holder
upon redemption, and shall state that from and after the redemption date
dividends will cease to accrue. If First BanCorp redeems less than all the
shares owned by a holder, the notice shall also specify the number of shares of
Series A Preferred Stock of the holder which are to be redeemed and the numbers
of the certificates representing such shares. Any notice mailed in accordance
with these procedures shall be conclusively presumed to have been properly
given, whether or not the stockholder receives this notice. The failure by First
BanCorp to give this notice by mail, or any defect in the notice, to the holders
of any shares designated for redemption shall not affect the validity of the
proceedings for the redemption of any other shares of Series A Preferred Stock.
 
     If the redemption notice is properly mailed and First BanCorp pays the
redemption price, from and after the redemption date, all dividends on the
shares of Series A Preferred Stock called for redemption shall cease to accrue
and all rights of the holders of the shares being redeemed as stockholders of
First BanCorp shall cease on the redemption date. Holders will retain the right
to receive the redemption price upon presentation of their stock certificates.
If First BanCorp redeems less than all the shares represented by any
certificate, a new certificate representing the unredeemed shares shall be
issued without cost to the holder.
 
                                       13
<PAGE>   17
 
     At its option, First BanCorp may, on or prior to the redemption date,
irrevocably deposit the entire amount payable upon redemption of the shares of
the Series A Preferred Stock to be redeemed with a bank or trust company
designated by First BanCorp having its principal office in New York, New York,
San Juan, Puerto Rico, or any other city in which First BanCorp shall at that
time maintain a transfer agent with respect to its capital stock, and having a
combined capital and surplus of at least $50,000,000. The depositary will hold
this amount in trust for payment to the holders of the shares of the Series A
Preferred Stock to be redeemed. If the deposit is made and the funds deposited
are immediately available to the holders of the shares of the Series A Preferred
Stock to be redeemed, First BanCorp will no longer have any obligation to make
payment of the amount payable upon redemption of the shares of the Series A
Preferred Stock to be redeemed. Following the deposit, except as discussed in
the next paragraph, holders of these shares shall look only to the depositary
for payment.
 
     Any funds remaining unclaimed at the end of two years after the redemption
date for which these funds were deposited shall be returned to First BanCorp.
After the funds are returned to First BanCorp, the holders of shares called for
redemption shall look only to First BanCorp for the payment of the redemption
price. Any interest accrued on any funds deposited with the depositary will
belong to First BanCorp and shall be paid to it on demand.
 
     After the redemption of any shares of the Series A Preferred Stock, the
redeemed shares will have the status of authorized but unissued shares of
preferred stock, without designation as to series, until these shares are once
more designated as part of a particular series by the board of directors of
First BanCorp.
 
Certain Regulatory Considerations Affecting Redemptions
 
     Under current regulations, First BanCorp may not redeem the Series A
Preferred Stock, without the prior approval of the Federal Reserve Board.
Ordinarily, the Federal Reserve Board will not permit a redemption unless (1)
the shares are redeemed with the proceeds of a sale of common stock or perpetual
preferred stock, or (2) the Federal Reserve Board determines that First
BanCorp's condition and circumstances warrant the reduction of a source of
permanent capital.
 
     Also, under Puerto Rico law, First BanCorp may not redeem any shares of its
capital stock unless the assets remaining after the redemption are sufficient to
pay any debts for which payment has not otherwise been provided.
 
LIQUIDATION PREFERENCE
 
     Upon any liquidation, dissolution, or winding up of First BanCorp, the
record holders of shares of Series A Preferred Stock will be entitled to receive
out of the assets of First BanCorp available for distribution to shareholders,
before any distribution is made to holders of common stock or any other equity
securities of First BanCorp ranking junior upon liquidation to the Series A
Preferred Stock, the amount of $25.00 per share plus an amount equal to any
accrued and unpaid dividends for the current monthly dividend period to the date
of payment.
 
     If First BanCorp is liquidated or dissolved and the amounts payable with
respect to the Series A Preferred Stock and any other shares of stock of equal
rank upon liquidation are not paid in full, the holders of the Series A
Preferred Stock and of the other shares will share ratably in any such
distribution of assets in proportion to the full liquidation preferences to
which each would otherwise be entitled. After payment of the full amount of the
liquidation preference to which they are entitled, the holders of shares of
Series A Preferred Stock will not be entitled to any further participation in
any distribution of assets of First BanCorp.
 
     A consolidation or merger of First BanCorp with any other corporation, or
any sale, lease or conveyance of all or any part of the property or business of
First BanCorp, shall not be deemed to be a liquidation, dissolution, or winding
up of First BanCorp.
 
                                       14
<PAGE>   18
 
VOTING RIGHTS
 
     Holders of the Series A Preferred Stock will not be entitled to receive
notice of or attend or vote at any meeting of stockholders of First BanCorp,
except as described below.
 
     If First BanCorp does not declare and pay dividends in full on the Series A
Preferred Stock for eighteen monthly dividend periods, whether consecutive or
not, the holders of outstanding shares of the Series A Preferred Stock, together
with the holders of any other shares of stock having the right to vote for the
election of directors solely in the event of any failure to pay dividends,
acting as a single class, will be entitled to appoint two additional members of
the board of directors of First BanCorp. They will also have the right to remove
any member so appointed from office and appoint another person in place of such
member. To make this appointment, the holders of a majority in liquidation
preference of these shares must send written notice to First BanCorp of the
appointment or pass a resolution adopted by a majority of holders at a separate
general meeting of those holders called for this purpose.
 
     Not later than 30 days after the right of holders of Series A Preferred
Stock to elect directors arises, if written notice by a majority of the holders
has not been given as provided for in the preceding sentence, the board of
directors of First BanCorp or an authorized board committee is required to call
a separate general meeting for this purpose. If the board of directors fails to
convene this meeting within the 30-day period, the holders of 10% of the
outstanding shares of the Series A Preferred Stock and any such other stock will
be entitled to convene the meeting.
 
     The provisions of the Certificate of Incorporation and By-laws of First
BanCorp relating to the convening and conduct of general meetings of
stockholders will apply to any separate general meeting of this type. Any member
of the board of directors appointed as described above shall vacate office if
First BanCorp resumes the payment of dividends in full on the Series A Preferred
Stock and each other series of stock having similar voting rights for twelve
consecutive monthly dividend periods, subject always to the revesting of the
right of holders of the Series A Preferred Stock, together with the holders of
any other shares of stock having the right to vote for the election of directors
solely in the event of any failure to pay dividends, acting as a single class,
to elect two directors as provided above in the event of any subsequent failure
on the part of First BanCorp to pay dividends at the stated rate for eighteen
monthly dividend periods, whether consecutive or not.
 
     The Certificate of Incorporation of First BanCorp requires a minimum of
five members of the board of directors and a maximum of fifteen members and that
the number of members must always be an odd number. The actual number of
directors is established by a resolution adopted by the absolute majority of the
members of First BanCorp's board of directors. As of the date of this
prospectus, First BanCorp's board of directors consisted of eleven members.
 
     Any change or cancellation of the rights and preferences of the Series A
Preferred Stock will require the approval of holders of at least two thirds of
the outstanding aggregate liquidation preference of the Series A Preferred
Stock. This approval can by evidenced either by a consent in writing or by a
resolution passed at a meeting of the holders of the Series A Preferred Stock.
The authorization or issuance of any shares of First BanCorp ranking senior to
the Series A Preferred Stock as to dividend rights or rights on liquidation or
similar events, will be considered a change requiring the consent of the Series
A Preferred Stock. Conversely, the authorization or issuance of shares ranking,
as to dividend rights or rights on liquidation or similar events, on a parity or
junior to the Series A Preferred Stock, will not be considered a change or
abrogation of the rights of the Series A Preferred Stock and the consent of the
holders of the Series A Preferred Stock will not be required in connection with
this action.
 
     No vote of the holders of the Series A Preferred Stock will be required for
First BanCorp to redeem or purchase and cancel the Series A Preferred Stock in
accordance with the Certificate of Incorporation of First BanCorp or the
Certificate of Designation for the Series A Preferred Stock.
 
     First BanCorp will cause a notice of any meeting at which holders of the
Series A Preferred Stock are entitled to vote to be mailed to each record holder
of the Series A Preferred Stock. Each notice will contain (1) the date of the
meeting, (2) a description of any resolution to be proposed for adoption at the
meeting, and (3) instructions for deliveries of proxies.

Certain Regulatory Issues Related to Voting Rights
 
     Under regulations adopted by the Federal Reserve Board, if the holders of
shares of Series A Preferred Stock become entitled to vote for the election of
directors as described above, the Series A Preferred Stock could be deemed a
"class of voting securities." In this instance, a holder, other than a natural
person, of 25% or more of the Series A Preferred Stock could then be subject to
regulation as a bank holding company in accordance with the Bank Holding Company
Act. A holder, other than a natural person, of 5% that otherwise exercises a
"controlling influence" over First BanCorp could also be subject to regulation
under the Bank Holding Company Act. In addition, at any time the Series A
Preferred Stock is deemed a class of voting securities, (1) any other bank
holding company may be required to obtain the approval of the Federal Reserve
Board to acquire or retain 5% or more of the outstanding shares of Series A
Preferred Stock, and (2) any person other than a bank holding company may be
required to file with the Federal Reserve Board under the Change in Bank Control
Act to acquire or retain 10% or more of such series.
 
     Section 12 of the Puerto Rico Banking Law requires that the Commissioner of
Financial Institutions of Puerto Rico approve any change of control involving a
bank organized under the Banking Law. The Banking Law requires that the
Commissioner be informed not less than 60 days prior to any transfer of voting
stock of a Puerto Rico bank that results in any person owning, directly or
indirectly, more than 5% of the outstanding voting stock of the bank. For the
purposes of Section 12 of the Banking Law, the term "control" means the power
to, directly or indirectly, direct or influence decisively the administration or
the norms of the bank. The Commissioner has made an administrative determination
that these provisions of the Banking Law are applicable to a change in control
of First BanCorp.
 
     Pursuant to the Banking Law, if the Commissioner receives notice of a
proposed transaction that may result in a change of control of First BanCorp,
the Commissioner is required to investigate and determine whether a change of
control has occurred. The Commissioner will issue an authorization for the
transfer of control of First BanCorp if the results of its investigations are in
its judgment satisfactory. The decision of the Commissioner is final and
unreviewable.
 
RANK
 
     The Series A Preferred Stock will, with respect to dividend rights and
rights on liquidation, winding up and dissolution, rank:
 
     - senior to all classes of common stock of First BanCorp, and to all other
       equity securities issued by First BanCorp the terms of which specifically
       provide that those equity securities will rank junior to the Series A
       Preferred Stock;
 
     - on a parity with all other equity securities issued by First BanCorp the
       terms of which specifically provide that those equity securities will
       rank equal to the Series A Preferred Stock; and
 
     - junior to all equity securities issued by First BanCorp the terms of
       which specifically provide that those equity securities will rank senior
       to the Series A Preferred Stock.
 
     For this purpose, the term "equity securities" does not include debt
securities convertible into or exchangeable for equity securities.
 
     First BanCorp may not issue shares ranking, as to dividend rights or rights
on liquidation, winding up and dissolution, senior to the Series A Preferred

                          DESCRIPTION OF CAPITAL STOCK
 
AUTHORIZED CAPITAL
 
     First BanCorp is authorized to issue 250,000,000 shares of common stock,
$1.00 par value, and 50,000,000 shares of preferred stock, $1.00 par value. The
following is a summary of certain rights and privileges of the common stock and
preferred stock. Statements in this summary are qualified in their entirety by
reference to First BanCorp's Certificate of Incorporation and to the General
Corporation Law of Puerto Rico.
 
COMMON STOCK
 
     As of March 15, 1999, there were 29,145,552 issued and outstanding shares
of common stock of First BanCorp. As of that date, a total of 3,124,518 of First
BanCorp's authorized but unissued shares of common stock were reserved for
issuance in connection with FirstBank's 1997 Stock Option Plan. The common stock
is listed on the New York Stock Exchange under the symbol "FBP." The holders of
the common stock are entitled to one vote for each share held of record on all
matters submitted to a vote of stockholders. Each share of common stock has the
same relative rights as, and is identical in all respects with, each other share
of common stock. There are no cumulative voting rights for the election of
directors.
 
     In the event of the liquidation, dissolution or distribution of assets of
First BanCorp, the holders of common stock are entitled to share ratably in the
assets legally available for distribution to common stockholders. The common
stock has no redemption, conversion or sinking fund privileges.
 
     Subject to any dividend preferences which may be established with respect
to any series of preferred stock, the holders of common stock are entitled to
receive, pro rata, dividends when and as declared by the board of directors out
of funds legally available for the payment of dividends.
 
     Holders of common stock do not have preemptive rights to subscribe for or
purchase additional securities of First BanCorp. The Bank of New York is the
transfer agent and registrar for the common stock.
 
PREFERRED STOCK
 
     First BanCorp's Certificate of Incorporation authorizes the board of
directors to approve the issuance of shares of preferred stock with such
designations and preferences as the board of directors may from time to time
determine. The board of directors is authorized, generally without stockholder
approval, to fix the designation, voting powers, preferences, limitations or
restrictions, and relative rights of any series of First BanCorp's preferred
stock at the time of issuance. As of the date of this prospectus, none of the
authorized shares of First BanCorp's preferred stock is issued and outstanding.
 
RESTRICTIONS OF ACQUISITION OF FIRST BANCORP
 
     Certain provisions of First BanCorp's Certificate of Incorporation and
By-Laws may have the effect of discouraging unilateral tender offers or other
attempts to take over and acquire First BanCorp. The following discussion is a
general summary of those provisions of First BanCorp's Certificate of
Incorporation and By-Laws which may be deemed to have a potential
"anti-takeover" effect. Reference should be made in each case to First BanCorp's
Certificate of Incorporation and By-Laws, copies of which are incorporated by
reference as exhibits to the registration statement of which this prospectus is
a part.
 
     Classified Board of Directors.  First BanCorp's Certificate of
Incorporation contains provisions relating to the board of directors and
provides, among other things, that the board of directors shall be divided into
three classes as nearly equal in number as possible with the term of office of
each class expiring each year. Said provision provides a greater likelihood of
continuity, knowledge and experience on the board of directors because at any
one time, one third of the board of directors would be in its second year of
service and one third of the board of directors would be in its third year of
service. In addition, said provision would cause any person who may be
attempting to take over First BanCorp to have to deal with the current board of
directors
 
                                       18
<PAGE>   22
 
because such person, even if it owns a majority of the shares, would be unable
to change the majority of the board of directors in any one annual meeting of
shareholders.
 
     Vacancies on the Board of Directors.  First BanCorp's Certificate of
Incorporation provides that any vacancy occurring in the board of directors,
including an increase in the number of authorized directors, may be filled by
the affirmative vote of a majority of the directors then in office, though less
than a quorum of the board of directors, and a director elected to fill a
vacancy shall serve for the remainder of the term to which the director has been
elected and until such director's successor shall have been elected and
qualified.
 
     Removal of Directors.  Both the Certificate of Incorporation and By-Laws of
First BanCorp provide that at a meeting of stockholders called expressly for the
removal of directors, any director may be removed for cause by a vote of 75% of
the shares then entitled to vote at an election of directors. Notwithstanding
the above, directors may be removed if required by regulatory authorities or by
law.
 
     Approval of Business Combinations.  The Certificate of Incorporation of
First BanCorp requires in cases of certain business combinations, such as
mergers, consolidations, reclassifications of securities and sale or other
transfer of all or substantially all of the assets of First BanCorp, that such
transactions must be approved by the affirmative vote of holders of not less
than 75% of the total number of outstanding shares of First BanCorp, subject to
certain limited exceptions described in Article Tenth of the Certificate of
Incorporation of First BanCorp.
 
     Amendment of Certificate of Incorporation.  Amendments to First BanCorp's
Certificate of Incorporation require the approval of not less than a majority of
the total number of outstanding shares of capital stock of First BanCorp and, if
such amendment concerns the article of the Certificate of Incorporation which
governs the removal of directors and the approval of certain business
combinations, the approval of not less than 75% of the total number of
outstanding shares of capital stock of First BanCorp.
 
     Special Meetings of Stockholders.  First BanCorp's By-Laws provide that
special meetings of stockholders, for any purpose or purposes, may be called by
the President or by the board of directors.

                                    TAXATION
 
GENERAL
 
     In the opinion of Fiddler Gonzalez & Rodriguez, LLP, counsel to First
BanCorp, the following discussion summarizes the material Puerto Rico and United
States tax considerations relating to the purchase, ownership, sale, exchange
and redemption of Series A Preferred Stock.
 
     This discussion does not intend to describe all of the tax considerations
that may be relevant to a particular investor in light of that person's
particular circumstances and does not describe any tax consequences arising
under the laws of any state, locality or taxing jurisdiction other than Puerto
Rico and the United States. This discussion is based on the tax laws of Puerto
Rico and the United States as in effect on the date of this prospectus, and
regulations, administrative pronouncements and judicial decisions available on
or before such date and now in effect. All of the foregoing are subject to
change, which change could apply retroactively and could affect the continued
validity of this summary.
 
     YOU SHOULD CONSULT YOUR OWN TAX ADVISOR AS TO THE APPLICATION TO YOUR
PARTICULAR SITUATION OF THE TAX CONSIDERATIONS DISCUSSED BELOW, AS WELL AS THE
APPLICATION OF ANY STATE, LOCAL, FOREIGN OR OTHER TAX.
 
                              PUERTO RICO TAXATION
 
     The following discussion does not intend to cover all aspects of Puerto
Rico taxation that may be relevant to a purchaser of Series A Preferred Stock in
light of the purchaser's particular circumstances, or to purchasers subject to
special rules of taxation, such as life insurance companies, special
partnerships, Subchapter N corporations, registered investment companies, and
certain pension trusts.
 
     For purposes of the discussion below, the term "Puerto Rico corporation" is
used to refer to a corporation organized under the laws of Puerto Rico and the
term "foreign corporation" is used to refer to a corporation organized under the
laws of a jurisdiction other than Puerto Rico.
 
OWNERSHIP AND DISPOSITION OF SERIES A PREFERRED STOCK
 
Taxation of Dividends.
 
     General.  Distributions of cash or other property made by First BanCorp on
the Series A Preferred Stock will be treated as dividends to the extent that
First BanCorp has current or accumulated earnings and profits. To the extent
that a distribution exceeds First BanCorp's current and accumulated earnings and
profits, the distribution will be applied against and reduce the adjusted tax
basis of the Series A Preferred Stock in the hands of the holder. The excess of
any distribution of this type over the adjusted tax basis will be treated as
gain on the sale or exchange of the Series A Preferred Stock and will be subject
to income tax as described below.
 
     The following discussion regarding the income taxation of dividends on
Series A Preferred Stock received by individuals not residents of Puerto Rico
and foreign corporations not engaged in a trade or business in Puerto Rico
assumes that dividends will constitute income from sources within Puerto Rico.
Generally, a dividend paid by a Puerto Rico corporation will constitute income
from sources within Puerto Rico unless the corporation has derived less than 20%
of its gross income from sources within Puerto Rico for the three taxable years
preceding the year of the declaration of the dividend or for such part of such
period as the corporation has been in existence. First BanCorp has represented
that it has derived more than 20% of its gross income from Puerto Rico sources
on an annual basis since its incorporation in 1998.
 
     Individual Residents of Puerto Rico and Puerto Rico Corporations.  In
general, individuals who are residents of Puerto Rico will be subject to a
special 10% income tax (the "10% Special Tax") on dividends paid on the Series A
Preferred Stock. This tax is generally required to be withheld by First BanCorp.
An individual may elect for this withholding not to apply, and in that case he
or she will be required to include the amount of the dividend as ordinary income
and will be subject to income tax thereon at the normal income tax rates, which
may be up to 33%.
 
                                       20
<PAGE>   24
 
     Puerto Rico corporations will be subject to income tax on dividends paid on
the Series A Preferred Stock at the normal corporate income tax rates, subject
to the dividend received deduction discussed below. In the case of a Puerto Rico
corporation, no withholding will be imposed on dividends paid on the Series A
Preferred Stock. The dividend received deduction will be equal to 85% of the
dividend received, but the deduction may not exceed 85% of the corporation's net
taxable income. Based on the applicable maximum Puerto Rico normal corporate
income tax rate of 39%, the maximum effective income tax rate on these dividends
will be 5.85% after accounting for the dividend received deduction.
 
     As a practical matter, dividends on the Series A Preferred Stock held in
street name through foreign financial institutions or other securities
intermediaries not engaged in trade or business in Puerto Rico will generally be
subject to a separate 10% withholding tax imposed on foreign corporations. See
"-- Foreign Corporations." Accordingly, individuals resident of Puerto Rico who
desire to file an election out of the applicable 10% Special Tax and applicable
withholding tax should have their shares of Series A Preferred Stock issued and
registered in their own names. Similarly, Puerto Rico corporations that own
shares of Series A Preferred Stock and wish to avoid the withholding imposed on
foreign corporations should have their shares issued and registered in their own
names in order to ensure that no withholding is made on dividends.
 
     United States Citizens Not Residents of Puerto Rico.  Dividends paid on the
Series A Preferred Stock to a United States citizen who is not a resident of
Puerto Rico will be subject to the 10% Special Tax which will be withheld by
First BanCorp. These individuals may elect for the withholding not to apply, and
in that case he or she will be required to include the amount of the dividend as
ordinary income and will be subject to income tax thereon at the normal income
tax rates, which may be up to 33%. Notwithstanding this election, a separate 10%
withholding tax will be required on the amount of the dividend unless the
individual timely files with First BanCorp a withholding exemption certificate
to the effect that the individual's gross income from sources within Puerto Rico
during the taxable year does not exceed $1,300 if single or $3,000 if married.
Withholding exemption certificates will only be accepted by First BanCorp or its
agent from individuals who have the shares of Series A Preferred Stock
registered in their names. Individuals who hold shares of Series A Preferred
Stock in street name will not be eligible to file with First BanCorp or its
agent withholding exemption certificates.
 
     Individuals Not Citizens of the United States and Not Residents of Puerto
Rico.  Dividends paid on the Series A Preferred Stock to any individual who is
not a citizen of the United States and who is not a resident of Puerto Rico will
generally be subject to a 10% tax which will be withheld at source by First
BanCorp.
 
     Foreign Corporations.  The income taxation of dividends paid on the Series
A Preferred Stock to a foreign corporation will depend on whether or not the
corporation is engaged in a trade or business in Puerto Rico.
 
     A foreign corporation that is engaged in a trade or business in Puerto Rico
will be subject to the normal corporate income tax rates applicable to Puerto
Rico corporations on their net income that is effectively connected with the
trade or business in Puerto Rico. This income will include net income from
sources within Puerto Rico and certain items of net income from sources outside
Puerto Rico that are effectively connected with the trade or business in Puerto
Rico. Net income from sources within Puerto Rico will include dividends on the
Series A Preferred Stock. A foreign corporation that is engaged in a trade or
business in Puerto Rico will be entitled to claim the 85% dividend received
deduction discussed above in connection with Puerto Rico corporations.
 
     In general, foreign corporations that are engaged in a trade or business in
Puerto Rico are also subject to a 10% branch profits tax. However, dividends on
the Series A Preferred Stock received by these corporations will be excluded
from the computation of the branch profits tax liability of these corporations.
 
     A foreign corporation that is not engaged in a trade or business in Puerto
Rico will be subject to a 10% withholding tax on dividends received on the
Series A Preferred Stock.
 
     Partnerships.  Partnerships are generally taxed in the same manner as
corporations. Accordingly, the preceding discussion with respect to corporations
is equally applicable in the case of most partnerships.
 
                                       21
<PAGE>   25
 
Taxation of Gains upon Sales or Exchanges Other Than Redemptions.
 
     General.  The sale or exchange of Series A Preferred Stock will give rise
to gain or loss equal to the difference between the amount realized on the sale
or exchange and the tax basis of the Series A Preferred Stock in the hands of
the holder. Any gain or loss that is required to be recognized will be a capital
gain or loss if the Series A Preferred Stock is held as a capital asset by the
holder and will be a long-term capital gain or loss if the stockholder's holding
period of the Series A Preferred Stock exceeds six months.
 
     Individual Residents of Puerto Rico and Puerto Rico Corporations.  Gain on
the sale or exchange of Series A Preferred Stock by an individual resident of
Puerto Rico or a Puerto Rico corporation will generally be required to be
recognized as gross income and will be subject to income tax. If the stockholder
is an individual and the gain is a long-term capital gain, the gain will be
taxable at a maximum rate of 20%.
 
     If the stockholder is a Puerto Rico corporation and the gain is a long-term
capital gain, the gain will qualify for an alternative tax rate of 25%.
 
     United States Citizens Not Residents of Puerto Rico.  A United States
citizen who is not a resident of Puerto Rico will not be subject to Puerto Rico
income tax on the sale or exchange of Series A Preferred Stock if the gain
resulting therefrom constitutes income from sources outside Puerto Rico.
Generally, gain on the sale or exchange of Series A Preferred Stock will be
considered to be income from sources outside Puerto Rico if all rights, title
and interest in or to the Series A Preferred Stock are transferred outside
Puerto Rico, and if the delivery or surrender of the instruments that evidence
the Series A Preferred Stock is made to an office of a paying or exchange agent
located outside Puerto Rico. If the gain resulting from the sale or exchange
constitutes income from sources within Puerto Rico, an amount equal to 20% of
the payments received will be withheld at the source; and if the gain
constitutes a long-term capital gain, it will be subject to a tax at a maximum
rate of 20%. The amount of tax withheld at source will be creditable against the
shareholder's Puerto Rico income tax liability.
 
     Individuals Not Citizens of the United States and Not Residents of Puerto
Rico.  An individual who is not a citizen of the United States and who is not a
resident of Puerto Rico will be subject to the rules described above under
"-- United States Citizens Not Residents of Puerto Rico." However, if the gain
resulting from the sale or exchange of Series A Preferred Stock constitutes
income from sources within Puerto Rico, an amount equal to 25% of the payments
received will be withheld at the source; provided, that if the gain resulting
from the sale or exchange represents a capital gain from sources within Puerto
Rico, the individual will generally be subject to tax on this gain at a fixed
rate of 29%. The amount of tax withheld at source will be creditable against the
shareholder's Puerto Rico income tax liability.
 
     Foreign Corporations.  A foreign corporation that is engaged in a trade or
business in Puerto Rico will generally be subject to Puerto Rico corporate
income tax on any gain realized on the sale or exchange of Series A Preferred
Stock if the gain is (1) from sources within Puerto Rico or (2) from sources
outside Puerto Rico and effectively connected with a trade or business in Puerto
Rico. Any such gain will qualify for an alternative tax of 25% if it qualifies
as a long-term capital gain.
 
     In general, foreign corporations that are engaged in a trade or business in
Puerto Rico will also be subject to a 10% branch profits tax. In the computation
of this tax, any gain realized by these corporations on the sale or exchange of
Series A Preferred Stock and that is subject to Puerto Rico income tax will be
taken into account. However, a deduction will be allowed in the computation for
any income tax paid on the gain realized on the sale or exchange.
 
     A foreign corporation that is not engaged in a trade or business in Puerto
Rico will generally be subject to a corporate income tax rate of 29% on any
capital gain realized on the sale or exchange of Series A Preferred Stock if the
gain is from sources within Puerto Rico. Gain on the sale or exchange of Series
A Preferred Stock will generally not be considered to be from sources within
Puerto Rico if all rights, title and interest in or to the Series A Preferred
Stock are transferred outside Puerto Rico, and if the delivery or surrender of
the instruments that evidence the Series A Preferred Stock is made to an office
of a paying or exchange agent located outside Puerto Rico. If the gain resulting
from the sale or exchange constitutes income from sources within Puerto Rico, an
amount equal to 25% of the payments received will be withheld at the source and
be
                                       22
<PAGE>   26
 
creditable against the shareholder's Puerto Rico income tax liability. In the
case of such foreign corporation, no income tax will be imposed if the gain
constitutes income from sources outside Puerto Rico.
 
     Partnerships.  Partnerships are generally taxed as corporations.
Accordingly, the discussion with respect to corporations is equally applicable
to most partnerships.
 
Taxation of Redemptions.
 
     A redemption of shares of the Series A Preferred Stock for cash will be
treated as a distribution taxable as a dividend to the extent of First BanCorp's
current or accumulated earnings and profits if the redemption is essentially
equivalent to a dividend. Under regulations issued by the Department of the
Treasury of Puerto Rico (1) a redemption of stock that completely terminates a
shareholder's interest in a corporation does not constitute a dividend, and (2)
certain pro rata redemptions among all the shareholders will be treated as a
dividend. In situations not described by these regulations, the Department of
the Treasury of Puerto Rico will generally follow principles applied by United
States courts and the United States Internal Revenue Service under the United
States Internal Revenue Code, as amended to date (the "Code"), in determining
whether a distribution is essentially equivalent to a dividend. The Department
of the Treasury of Puerto Rico, however, is not bound by such principles and is
free to adopt a different rule.
 
     If the redemption of the Series A Preferred Stock is not treated as a
dividend, it will generally generate gain or loss that will be measured as
provided above under "-- Taxation of Gains upon Sales or Exchanges Other Than
Redemptions" for a sale or exchange of Series A Preferred Stock. Gain on the
redemption of Series A Preferred Stock will generally be recognized and will be
subject to income tax. If the stockholder of the Series A Preferred Stock is an
individual resident of Puerto Rico and the gain is a long-term capital gain, the
gain will be taxable at a maximum rate of 20%. If the stockholder is a Puerto
Rico corporation and the gain is a long-term capital gain, the gain will qualify
for the alternative tax rate of 25%.
 
     If the stockholder of the Series A Preferred Stock is an individual who is
not a resident of Puerto Rico or a foreign corporation or foreign partnership,
any gain realized by the holder on the redemption of the Series A Preferred
Stock that is not taxable as a dividend may be subject to Puerto Rico income tax
if the gain constitutes income from sources within Puerto Rico or is effectively
connected with a trade or business conducted by the holder in Puerto Rico. The
Puerto Rico income tax law does not provide clear rules in this area. As a
result thereof, these prospective shareholders should be aware that gain
realized from a redemption of the Series A Preferred Stock may be treated as
income from sources within Puerto Rico or income effectively connected with a
trade or business in Puerto Rico and subject to income tax accordingly.
 
ESTATE AND GIFT TAXATION
 
     The transfer of Series A Preferred Stock by inheritance or gift by an
individual who is a resident of Puerto Rico at the time of his or her death or
at the time of the gift will not be subject to estate and gift tax if the
individual is a citizen of the United States who acquired his or her citizenship
solely by reason of birth or residence in Puerto Rico. Other individuals should
consult their own tax advisors in order to determine the appropriate treatment
for Puerto Rico estate and gift tax purposes of the transfer of the Series A
Preferred Stock by death or gift.
 
MUNICIPAL LICENSE TAXATION
 
     Individuals and corporations that are not engaged in a trade or business in
Puerto Rico will not be subject to municipal license tax on dividends paid on
the Series A Preferred Stock or on any gain realized on the sale, exchange or
redemption of the Series A Preferred Stock.
 
     A corporation or partnership, Puerto Rico or foreign, that is engaged in a
trade or business in Puerto Rico will generally be subject to municipal license
tax on dividends paid on the Series A Preferred Stock and on the gain realized
on the sale, exchange or redemption of the Series A Preferred Stock if the
dividends or gain are attributable to that trade or business. The municipal
license tax is imposed on the volume of business of the
 
                                       23
<PAGE>   27
 
taxpayer, and the tax rates range from a maximum of 1.5% for financial
businesses to a maximum of 0.5% for other businesses.
 
PROPERTY TAXATION
 
     The Series A Preferred Stock will not be subject to property tax.
 
                             UNITED STATES TAXATION
 
     The following discussion is limited to the United States federal tax
consequences of the ownership and disposition of the Series A Preferred Stock by
U.S. Holders, as defined below, and corporations organized under the laws of
Puerto Rico ("PR Corporations"). This discussion is based on the Code, existing
and proposed regulations of the U.S. Department of the Treasury promulgated
thereunder, administrative pronouncements and judicial decisions, all of which
are subject to change, even with retroactive effect. This discussion deals only
with Series A Preferred Stock held by initial purchasers as capital assets
within the meaning of Section 1221 of the Code. It does not discuss all of the
tax consequences that may be relevant to a purchaser in light of that person's
particular circumstances or to purchasers subject to special rules, such as
entities that are taxed under the Code as partnerships, Subchapter S
corporations, life insurance companies, tax exempt entities, dealers in
securities, financial institutions, or to persons whose functional currency is
not the U.S. dollar.
 
     As used herein, the term "U.S. Holder" means a beneficial owner of Series A
Preferred Stock that does not own directly, constructively or by attribution,
10% or more of the voting stock of the First BanCorp and is, for United States
federal income tax purposes:
 
     - a citizen or resident of the United States,
 
     - a corporation organized under the laws of a state of the United States,
 
     - a corporation organized under the laws of the United States or of any
       political subdivision thereof, or
 
     - an estate or trust the income of which is subject to United States
       federal income taxation regardless of its source.
 
     The term "U.S. Holder" does not include individual Puerto Rico residents
who are not citizens or residents of the United States nor does it include PR
Corporations. As used herein, the term "Puerto Rico U.S. Holder" means an
individual U.S. Holder who is a bona fide resident of Puerto Rico during the
entire taxable year.
 
OWNERSHIP AND DISPOSITION OF SERIES A PREFERRED STOCK
 
Taxation of Dividends.
 
     General.  Dividends on the Series A Preferred Stock will constitute gross
income from sources outside the United States if less than 25% of the gross
income from all sources of First BanCorp for the three-year period ending with
the close of its taxable year preceding the declaration of such dividends (or
for such part of such period as First BanCorp has been in existence) was
effectively connected with a trade or business within the United States. Since
its incorporation in 1998, First BanCorp has not been engaged in a trade or
business in the United States, and therefore less than 25% of First BanCorp's
gross income has been effectively connected with the conduct of a trade or
business in the United States. Additionally, First BanCorp expects that in the
future less than 25% of its gross income will be effectively connected with the
conduct of a trade or business within the United States. Accordingly, dividends
on the Series A Preferred Stock distributed by First BanCorp will constitute
gross income from sources outside the United States so long as First BanCorp
continues to meet such gross income test.
 
     U.S. Holders other than Puerto Rico U.S. Holders.  Subject to the
discussion under "-- Passive Foreign Investment Company Rules" below,
distributions made with respect to the Series A Preferred Stock, including the
amount of any Puerto Rico taxes withheld on the distribution, will be includable
in the gross
 
                                       24
<PAGE>   28
 
income of a U.S. Holder, other than a Puerto Rico U.S. Holder, as foreign source
gross income to the extent the distributions are paid out of current or
accumulated earnings and profits of First BanCorp as determined for United
States federal income tax purposes. These dividends will not be eligible for the
dividends received deduction generally allowed to U.S. Holders that are
corporations. To the extent, if any, that the amount of any distribution by
First BanCorp exceeds its current and accumulated earnings and profits as
determined under United States federal income tax principles, the excess will be
treated first as a tax-free return of the U.S. Holder's tax basis in the Series
A Preferred Stock and thereafter as capital gain.
 
     Subject to certain conditions and limitations contained in the Code, the
Puerto Rico income tax imposed on dividends distributed by First BanCorp in
accordance with Puerto Rico law will be eligible for credit against the U.S.
Holder's United States federal income tax liability. See "Puerto Rico
Taxation -- Ownership and Disposition of Series A Preferred Stock -- Taxation of
Dividends" above. For purposes of calculating a U.S. Holder's United States
foreign tax credit limitation, dividends distributed by First BanCorp will
generally constitute foreign source "passive income" or, in the case of certain
U.S. Holders (those predominantly engaged in the active conduct of a banking,
financing or similar business), foreign source "financial services income."
 
     Puerto Rico U.S. Holders.  In general, and subject to the discussion under
"-- Passive Foreign Investment Company Rules" below, distributions of dividends
made by First BanCorp on the Series A Preferred Stock to a Puerto Rico U.S.
Holder will constitute gross income from sources within Puerto Rico, will not be
includable in the stockholder's gross income and will be exempt from United
States federal income taxation. In addition, for United States federal income
tax purposes, no deduction or credit will be allowed that is allocable to or
chargeable against amounts so excluded from the Puerto Rico U.S. Holder's gross
income.
 
     PR Corporations.  In general, distributions of dividends made by First
BanCorp on the Series A Preferred Stock to a PR Corporation will not, in the
hands of the PR Corporation, be subject to United States income tax if the
dividends are not effectively connected with a United States trade or business
of the PR Corporation. The Code provides special rules for PR Corporations that
are "Controlled Foreign Corporations," "Personal Holding Companies," "Foreign
Personal Holding Companies," or "Passive Foreign Investment Companies."
 
Taxation of Capital Gains upon Sales or Exchanges Including Redemptions.
 
     U.S. Holders other than Puerto Rico U.S. Holders.  A U.S. Holder, other
than a Puerto Rico U.S. Holder, will recognize gain or loss on the sale or other
disposition of Series A Preferred Stock, including redemptions treated as sales
or exchanges of the Series A Preferred Stock under Section 302 of the Code, in
an amount equal to the difference between the U.S. Holder's adjusted tax basis
in the Series A Preferred Stock and the amount realized on the sale or other
disposition. Subject to the discussion under "-- Passive Foreign Investment
Company Rules" below, the gain or loss will be a capital gain or loss. U.S.
Holders should consult their own tax advisors concerning the treatment of
capital gains and losses. Redemptions of the Series A Preferred Stock that are
not treated as sales or exchanges under Section 302 of the Code will generally
be subject to income tax under the Code as dividends.
 
     Gain recognized by a U.S. Holder on the sale or other disposition of Series
A Preferred Stock generally will be treated as United States source income.
 
     Puerto Rico U.S. Holders.  In general, and subject to the discussion under
"-- Passive Foreign Investment Company Rules" below, gain from the sale or
exchange of the Series A Preferred Stock, including redemptions treated as sales
or exchanges of the Series A Preferred Stock under Section 302 of the Code, by a
Puerto Rico U.S. Holder that is a resident of Puerto Rico for purposes of
Section 865 of the Code (1) will constitute income from sources within Puerto
Rico, (2) will not be includable in the stockholder's gross income and (3) will
be exempt from United States federal income taxation. Also, no deduction or
credit will be allowed that is allocable to or chargeable against amounts so
excluded from the Puerto Rico U.S. Holder's gross income. Redemptions of the
Series A Preferred Stock that are not treated as sales or exchanges under
Section 302 of the Code will generally be subject to income tax under the Code
as dividends.
                                       25
<PAGE>   29
 
     PR Corporations.  In general, any gain derived by a PR Corporation from the
sale or exchange of the Series A Preferred Stock will not, in the hands of the
PR Corporation, be subject to United States income tax if the gain is not
effectively connected with a United States trade or business of the PR
Corporation. The Code provides special rules for PR Corporations that are
"Controlled Foreign Corporations," "Personal Holding Companies," "Foreign
Personal Holding Companies," or "Passive Foreign Investment Companies."
Redemptions of the Series A Preferred Stock that are not treated as sales or
exchanges under Section 302 of the Code will generally be subject to income tax
under the Code as dividends.
 
     Backup Withholding.  Certain noncorporate U.S. Holders may be subject to
backup withholding at the rate of 31% on dividends paid or the proceeds of a
sale, exchange or redemption of Series A Preferred Stock. Generally, backup
withholding applies only when the taxpayer fails to furnish or certify a proper
taxpayer identification number or when the payor is notified by the IRS that the
taxpayer has failed to report payments of interest and dividends properly. U.S.
Holders should consult their own tax advisors regarding their qualification for
exemption from backup withholding and the procedure for obtaining any applicable
exemption.
 
PASSIVE FOREIGN INVESTMENT COMPANY RULES
 
     The Code provides special rules for distributions received by U.S. Holders
on stock of a Passive Foreign Investment Company ("PFIC") as well as amounts
received from the sale or other disposition of PFIC stock. For purposes of these
rules pledges are considered dispositions.
 
     Based upon certain proposed Treasury Regulations under the PFIC provisions
of the Code (the "Proposed Regulations"), First BanCorp believes that it has not
been a PFIC for any of its prior taxable years and expects to conduct its
affairs in a manner so that it will not meet the criteria to be considered a
PFIC in the foreseeable future. If, contrary to First BanCorp's expectation, the
Series A Preferred Stock were considered to be shares of a PFIC for any fiscal
year, a U.S. Holder would generally be subject to special rules, regardless of
whether First BanCorp remains a PFIC, with respect to (1) any "excess
distribution" by First BanCorp to the U.S. Holder and (2) any gain realized on
the sale, pledge or other disposition of Series A Preferred Stock. An "excess
distribution" is, generally, any distributions received by the U.S. Holder on
the Series A Preferred Stock in a taxable year that are greater than 125% of the
average annual distributions received by the U.S. Holder in the three preceding
taxable years, or the U.S. Holder's holding period for the Series A Preferred
Stock if shorter.
 
     Under these rules, (1) the excess distribution or gain would be allocated
ratably over the U.S. Holder's holding period for the Series A Preferred Stock,
(2) the amount allocated to the current taxable year and any taxable year prior
to the first taxable year in which First BanCorp is a PFIC would be taxed as
ordinary income, and (3) the amount allocated to each of the other taxable years
would be subject to tax at the highest rate of tax in effect for the applicable
class of taxpayer for that year, and an interest charge for the deemed deferral
benefit would be imposed on the resulting tax attributable to each such year.
 
     As an alternative to these rules, if First BanCorp were a PFIC and
effective for taxable years of U.S. Holders beginning after December 31, 1997,
U.S. Holders may, in certain circumstances, elect a mark-to-market treatment
with respect to their Series A Preferred Stock, provided that the Series A
Preferred Stock will constitute "marketable stock" for purposes of these rules.
 
     In general, the Proposed Regulations provide that Puerto Rico U.S. Holders
would be subject to the rule described in (3) above only to the extent that any
excess distribution or gain is allocated to a taxable year during which the
individual held the Series A Preferred Stock and was not a bona fide resident of
Puerto Rico during the entire taxable year or, in certain cases, a portion
thereof.
 
     Under current law, if First BanCorp is a PFIC in any year, a U.S. Holder
who beneficially owns Series A Preferred Stock during that year must make an
annual return on IRS Form 8621 that describes any distributions received from
First BanCorp and any gain realized on the disposition of Series A Preferred
Stock.

ESTATE AND GIFT TAXATION
 
     The transfer of Series A Preferred Stock by inheritance or gift by an
individual who is a resident of Puerto Rico at the time of his or her death or
at the time of the gift will not be subject to U.S. federal estate and gift tax
if the individual is a citizen of the United States who acquired his or her
citizenship solely by reason of birth or residence in Puerto Rico. Other
individuals should consult their own tax advisors in order to determine the
appropriate treatment for U.S. federal estate and gift tax purposes of the
transfer of the Series A Preferred Stock by death or gift.

(1) Assumes no exercise of the underwriters' over-allotment option.
 
     Under the terms and conditions of the Underwriting Agreement, First BanCorp
is obligated to sell, and the underwriters are obligated to purchase, all of the
shares of Series A Preferred Stock shown in the table above, if any of the
shares of Series A Preferred Stock are purchased.
 
     The underwriters propose to offer the shares of Series A Preferred Stock to
the public initially at the public offering price set forth on the cover page of
this prospectus and to certain selected dealers at the public offering price
less a concession not to exceed $          per share. After the offering to the
public, the public offering price and the concession to selected dealers may be
changed by the underwriters.
 
     First BanCorp has granted the underwriters an option exercisable for 30
days from the date of this prospectus, to purchase up to 540,000 additional
shares of Series A Preferred Stock to cover over-allotments, if any, at the
initial public offering price, less the underwriting discounts, as shown on the
cover page of this prospectus. If the underwriters exercise this option, then
each of the underwriters will have a firm commitment, subject to certain
conditions contained in the Underwriting Agreement, to purchase a number of
option shares proportionate to the underwriter's initial commitment as indicated
in the table above. The underwriters may exercise this option only to cover
over-allotments made in connection with the sale of the shares of Series A
Preferred Stock offered hereby.
 
     The following table shows the per share and total underwriting discounts
and commissions to be paid to the underwriters by First BanCorp as well as the
proceeds received by First BanCorp from the offering, before deducting expenses.
The amounts are shown assuming both no exercise and full exercise of the
underwriters' option to purchase up to an additional 540,000 shares.

     Until the distribution of the Series A Preferred Stock is completed, rules
of the Securities and Exchange Commission may limit the ability of the
underwriters to bid for and purchase the Series A Preferred Stock. As an
exception to these rules, the underwriters may engage in certain transactions
that stabilize the price of the Series A Preferred Stock. These transactions
consist of bids or purchases for the purpose of pegging, fixing or maintaining
the price of the Series A Preferred Stock.

     If the underwriters create a short position in the Series A Preferred Stock
in connection with the offering, i.e., if the underwriters sell more shares of
Series A Preferred Stock than are set forth on the cover page of this
prospectus, they may reduce that short position by purchasing shares of Series A
Preferred Stock in the open market. The underwriters may also elect to reduce
any short position by purchasing all or part of the over-allotment option
described above.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of these purchases.
 
     First BanCorp estimates that the total expenses of this offering, excluding
underwriting discounts and commissions, will be $300,000.
 
     In connection with this offering, First BanCorp has agreed to indemnify the
underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, or to contribute to payments that the underwriters may
be required to make in respect thereof.
 
     The Series A Preferred Stock has been approved for listing on the New York
Stock Exchange under the symbol "FBPP," subject to official notice of issuance.
 
     Several of the underwriters have from time to time been customers of,
engaged in transactions with, or performed services for, First BanCorp and its
subsidiaries in the ordinary course of business. The underwriters may continue
to do so in the future.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     (a) Article 4.09 of the Puerto Rico General Corporation Law authorizes
Puerto Rico corporations to indemnify their officers and directors against
liabilities arising out of pending or threatened actions, suits or proceedings
to which they are or may be made parties by reason of being directors or
officers. Such rights of indemnification are not exclusive of any other rights
to which such officers or directors may be entitled under any by-law, agreement,
vote of stockholders or otherwise. The Certificate of Incorporation provides
that First BanCorp shall indemnify its directors, officers and employees to the
fullest extent permitted by law. First BanCorp also maintains directors' and
officers' liability insurance on behalf of its directors and officers.
 
     (b) Article Ninth, Section 1 of the Certificate of Incorporation provides
that First BanCorp shall indemnify any person who was or is a party or is
threatened to be made a party to any threatened, pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative
(other than an action by or in the right of First BanCorp) by reason of the fact
that he is or was a director, officer, employee or agent of First BanCorp or is
or was serving at the request of First BanCorp as a director, officer, employer
or agent of another corporation or enterprise, against expenses (including
attorneys' fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by him in connection with such action, suit or proceeding if
he acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of First BanCorp, and, with respect to any
criminal action or proceeding, had no reasonable cause to believe his conduct
was unlawful.
 
     Article Ninth, Section 2 of the Certificate of Incorporation provides that
First BanCorp shall indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action or suit by or
in the right of First BanCorp to procure a judgment in its favor by reason of
the fact that such person acted in any of the capacities set forth above,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by him in connection with the
defense or settlement of such action or suit if he acted under similar standards
set forth in the preceding paragraph, except that no indemnification may be made
in respect of any claim, issue or matter as to which such person shall have been
adjudged to be liable to First BanCorp unless and only to the extent that the
court in which such action or suit was brought shall determine that despite the
adjudication or liability, such person is fairly and reasonably entitled to be
indemnified for such expenses which the court shall deem proper.
 
     Article Ninth, Section 3 of the Certificate of Incorporation provides that
to the extent a director, officer, employee or agent of First BanCorp has been
successful on the merits or otherwise in the defense of any action, suit or
proceeding referred to in Sections 1 and 2 of Article Ninth of the Certificate
of Incorporation or
 
                                      II-1
<PAGE>   36
 
in the defense of any claim, issue, or matter therein, he shall be indemnified
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection therewith. Section 4 of Article Ninth of the Certificate of
Incorporation provides that any indemnification by First BanCorp under Sections
1 and 2 of Article Ninth of the Certificate of Incorporation shall be made only
as authorized in the specific case upon a determination that indemnification of
such person is proper under the circumstances because such person has met the
applicable standard of conduct set forth therein. Such determination shall be
made (a) by the board of directors by a majority vote of a quorum consisting of

(1) Incorporated by reference to the Form S-4 Registration Statement (Reg. No.
    333-08640), filed by First BanCorp. with the Commission on April 15, 1998,
    as amended.
 
ITEM 17.  UNDERTAKINGS.
 
     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
Exchange Act of 1934 that is incorporated by reference in the registration
statement shall be deemed to be a new registration statement relating to the
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
 
     The Registrant hereby undertakes that:
 
          (2) For purposes of determining any liability under the Securities Act
              of 1933, the information omitted from the form of prospectus filed
              as part of this registration statement in reliance upon Rule 430A
              and contained in a form of prospectus filed by the Registrant
              pursuant to Rule 424(b) (1) or (4) or 497(h) under the Securities
              Act of 1933 shall be deemed to be part of this registration
              statement as of the time it was declared effective.
 
          (3) For the purpose of determining any liability under the Securities
              Act of 1933, each post-effective amendment that contains a form of
              prospectus shall be deemed to be a new registration statement
              relating to the securities offered therein, and the offering of
              such securities at that time shall be deemed to be the initial
              bona fide offering thereof.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of First
BanCorp pursuant to the provision described under Item 15 above, or otherwise,
First BanCorp has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Securities Act of 1933 and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than the
payment by First BanCorp of expenses incurred or paid by a director, officer, or
controlling person of First BanCorp in the successful defense of any action,
suit, or proceeding) is asserted by such director, officer, or controlling
person in connection with the securities being registered, First BanCorp will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

PAINEWEBBER INCORPORATED OF PUERTO RICO
As lead underwriter of the several Underwriters 
named in Schedule 1
American International Plaza, PH 
Hato Rey, Puerto Rico 00918

Ladies and Gentlemen:

         FIRST BANCORP., a Puerto Rico corporation (the "Company"), proposes to
sell an aggregate of 3,600,000 shares (the "Firm Shares") of the Company's __%
Noncumulative Perpetual Monthly Income Preferred Stock, Series A (the "Preferred
Stock"), which are to be issued and sold by the Company to you and the other
underwriters named in Schedule 1 hereto (collectively, the "Underwriters"), for
whom you are acting as representative (the "Representative"). The Company also
has agreed to grant to you and the other Underwriters an option (the "Option")
to purchase up to an additional 540,000 shares of Preferred Stock (the "Option
Shares") on the terms and for the purposes set forth in Section 1(b) hereto. The
Firm Shares and the Option Shares are hereinafter collectively referred to as
the "Shares."

         The Company hereby confirms as follows its agreements with the
Representative and the several other Underwriters.

         1.       Agreement to Sell and Purchase.

                  (a) On the basis of the representations, warranties and
agreements of the Company herein contained and subject to all the terms and
conditions of this Agreement, the Company agrees to sell to each Underwriter and
each Underwriter, severally and not jointly, agrees to purchase from the Company
at a purchase price of $24.2125 per share, the number of Firm Shares set forth
opposite the name of such Underwriter in Column (1) of Schedule 1 hereto, plus
such 
<PAGE>   2
                                        2

additional number of Firm Shares which such Underwriter may become obligated to
purchase pursuant to Section 9 hereof.

                  (b) Subject to all the terms and conditions of this Agreement,
the Company grants the Option to the several Underwriters to purchase, severally
and not jointly, the Option Shares at the same price per share as the
Underwriters shall pay for the Firm Shares. The Option may be exercised only to
cover overallotments in the sale of the Firm Shares by the Underwriters and may
be exercised in whole or in part at any time and from time to time on or before
the 30th day after the date of this Agreement (or on the next business day if
the 30th day is not a business day), upon notice (the "Option Shares Notice") in
writing or by telephone (confirmed in writing) by the Representative to the
Company no later than 5:00 p.m., Atlantic Standard time, at least two and no
more than five business days before the date specified for closing in the Option
Shares Notice (the "Option Closing Date") setting forth the aggregate number of
Option Shares to be purchased and the time and date for such purchase. On the
Option Closing Date, the Company will issue and sell to the Underwriters the
number of Option Shares set forth in the Option Shares Notice and each
Underwriter will purchase such percentage of the Option Shares as is equal to
the percentage of Firm Shares that such Underwriter is purchasing hereunder, as
adjusted by the Representative in such manner as it deems advisable to avoid
fractional shares.

         2. Delivery and Payment. Delivery of the Firm Shares shall be made to
the Representative for the accounts of the Underwriters at the office of
Axtmayer Adsuar Muniz & Goyco, P.S.C., counsel to the Underwriters, 268 Munoz
Rivera Ave.,Suite 1400, Hato Rey, P.R. 00918, against payment of the purchase
price by wire transfer of immediately available funds to the bank account
designated by the Company. Such payment shall be made at 10:00 a.m., New York
City time, on the third full business day following the date of this Agreement,
or at such other time on such other date, not later than seven business days
after the date of this Agreement, as may be agreed upon by the Company and the
Representative (such date is hereinafter referred to as the "Closing Date").
Time shall be of the essence and delivery at the time and place specified
pursuant to this Agreement is a further condition of the obligation of each
Underwriter hereunder.

         To the extent the Option is exercised, delivery of the Option Shares
against payment by the Underwriters (in the manner specified above) will take
place at the offices specified above for the Closing Date at the time and date
(which may be the Closing Date) specified in the Option Shares Notice.

         Certificates evidencing the Shares shall be in definitive form and
shall be registered in such names and in such denominations as the
Representative shall request at least two business days prior to the Closing
Date or the Option Closing Date, as the case may be, by written notice to the
Company. For the purpose of expediting the checking and packaging of
certificates for the Shares, the Company agrees to make such certificates
available for inspection at least 24 hours prior to the Closing Date or the
Option Closing Date, as the case may be.

         The cost of original issue tax stamps, if any, in connection with the
issuance, sale and delivery of the Firm Shares and Option Shares by the Company
to the respective Underwriters shall be borne by the Company. The Company will
pay and save each Underwriter and any subsequent holder of the Shares harmless
from any and all liabilities with respect to or resulting from any failure or
delay in paying Federal, state or Commonwealth of Puerto Rico stamp and other
transfer taxes, if any, which may be payable or determined to be payable in
connection with the original issuance, sale or delivery to such Underwriter of
the Firm Shares and Option Shares.

and Regulations or in a term sheet described in Rule 434 of the Rules and

therein as of the Effective Date by Rule 430A of the Rules and Regulations and
including any registration statement filed pursuant to Rule 462(b) of the Rules
and Regulations (a "Rule 462 Registration Statement") increasing the size of the

Preliminary Prospectus or the Prospectus shall be deemed to include all
documents and information incorporated by reference therein and shall be deemed
to refer to and include any documents and information filed after the date of
such Preliminary Prospectus or Prospectus, as the case may be, and so
incorporated by reference, under the Securities Exchange Act of 1934, as amended
(the "Exchange Act").

                  (b) On the date that any Preliminary Prospectus was filed with
the Commission, the date the Prospectus is first filed with the Commission
pursuant to Rule 424(b) (if required), at all times subsequent to and including
the Closing Date and, if later, the Option Closing Date and when any
post-effective amendment to the Registration Statement becomes effective or any
amendment or supplement to the Prospectus is filed with the Commission, the
Registration Statement, each Preliminary Prospectus and the Prospectus (as
amended or as supplemented if the Company shall have filed with the Commission
any amendment or supplement thereto), including the financial statements
included in the Prospectus, did or will comply with all applicable provisions of
the Act and the Rules and Regulations and did or will contain all statements
required to be stated therein in accordance with the Act and the Rules and
Regulations. On the Effective Date and when any post-effective amendment to the
Registration Statement becomes effective, no part of the Registration Statement
or any such amendment did or will contain any untrue statement of a material
fact or omit to state a material fact required to be stated therein or necessary
in order to make the statements therein not misleading. At the Effective Date,
the date the Prospectus or any amendment or supplement to the Prospectus is
filed with the Commission and at the Closing Date and, if later, the Option
Closing Date, the Prospectus did not or will not contain any untrue statement of
a material fact or omit to state a material fact necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. The foregoing representations and warranties in this
Section 3(b) do not apply to any statements or omissions made in reliance on and
in conformity with information relating to any Underwriter furnished in writing
to the Company by the Representative specifically for inclusion in the
Registration Statement, each Preliminary Prospectus or Prospectus or any
amendment or supplement thereto. There are no contracts or other documents
required to be filed as exhibits to the Registration Statement by the Act or the
Rules and Regulations that have not been so filed. The documents which are
incorporated by reference in any Preliminary Prospectus or the Prospectus or
from which information is so incorporated by reference, when they became
effective or were filed with the Commission, as the case may be, complied in all
material respects with the requirements of the Act and the Rules and Regulations
or the Exchange Act and the rules and regulations thereunder, as applicable, and
did not, when such documents were so filed, contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary in order to make the statements therein, in light of the circumstances
under which they were made, not misleading, and any documents so filed and
incorporated by reference subsequent to the effective date of the Registration
Statement shall, when they are filed

                                        5


with the Commission, conform in all material respects with the requirements of
the Act and the Rules and Regulations and the Exchange Act and the rules and
regulations thereunder, as applicable.

                  (c) The only directly or indirectly controlled subsidiaries of
the Company (each, a "Subsidiary" and collectively, the "Subsidiaries") are
those listed on Exhibit A hereto. Except as set forth in the Prospectus (or if
the Prospectus is not in existence, in the most recent Preliminary Prospectus)
or as acquired in connection with the exercise of its rights as a creditor, or
pursuant to a bona fide collateral pledge arrangement, neither the Company nor
any Subsidiary owns, nor at the Closing Date and the Option Closing Date, will
own an interest in any corporation, partnership, trust, joint venture or other
business entity. The Company has been and, at the Closing Date and Option
Closing Date, will be duly organized and validly existing as a corporation under
the laws of the Commonwealth of Puerto Rico and is and, at the Closing Date and
Option Closing Date, will be in good standing with the Commonwealth of Puerto
Rico. The Company is registered as a bank holding company under the Bank Holding
Company Act of 1956 (the "BHCA") and is and, at the Closing Date and Option
Closing Date will be in good standing with the Board of Governors of the Federal
Reserve System (the "Federal Reserve"). Each of the Subsidiaries is and, at the
Closing Date and Option Closing Date, will be a corporation duly organized,
validly existing and in good standing under the laws of its respective
jurisdiction of incorporation. Each of the Company and its Subsidiaries is and,
at the Closing Date and the Option Closing Date, will be duly qualified and in
good standing as a foreign corporation in each jurisdiction in which the
character or location of its properties (owned, leased or licensed) or the
nature or conduct of its business or use of its property and assets makes such
qualification necessary, except where the failure to so qualify would not have a
material adverse effect on the condition, financial or otherwise, or the
earnings, prospects or business affairs of the Company and its Subsidiaries
taken as a whole.

                  (d) The outstanding shares of capital stock of the Company
have been duly authorized and validly issued and are fully paid and
nonassessable and are not subject to any preemptive or similar rights. The
Shares to be issued and sold by the Company will be, upon such issuance and
payment therefor, duly authorized, validly issued, fully paid and nonassessable
and will not be subject to any preemptive or similar rights. The Company has,
and, upon completion of the sale of the Shares, will have, an authorized, issued
and outstanding capitalization as set forth in the Registration Statement and
the Prospectus (or, if the Prospectus is not in existence, in the most recent
Preliminary Prospectus). The description of the securities of the Company in the
Registration Statement and the Prospectus (or, if the Prospectus is not in
existence, the most recent Preliminary Prospectus) is, and at the Closing Date
and, if later, the Option Closing Date, will be, complete and accurate in all
respects. No holders of securities of the Company are entitled to have such
securities registered under the Registration Statement, except where such rights
have been waived.

                  (e) The consolidated financial statements and the related
notes of the Company included in the Registration Statement or incorporated
therein by reference and the Prospectus (or, if the Prospectus is not in
existence, in the most recent Preliminary Prospectus) present fairly the
financial condition of the Company and its Subsidiaries as of the dates
indicated and the

<PAGE>   6
                                        6


consolidated results of operations, and cash flows of the Company and its
Subsidiaries for the periods covered thereby, all in conformity with generally
accepted accounting principles ("GAAP") applied on a consistent basis throughout
the entire periods involved. PricewaterhouseCoopers LLP (the "Accountants"), who
have reported on those of such financial statements and related notes which are
audited, are independent accountants with respect to the Company and its
Subsidiaries within the meaning of the Act and the applicable and published
rules and regulations.

                  (f) The Company maintains a system of internal accounting
controls sufficient to provide reasonable assurance that (i) transactions are
executed in accordance with management's general or specific authorization, (ii)
transactions are recorded as necessary to permit preparation of financial
statements in conformity with GAAP and to maintain accountability for assets,
(iii) access to assets is permitted only in accordance with management's general
or specific authorization, and (iv) the recorded accountability for assets is
compared with existing assets at reasonable intervals and appropriate action is
taken with respect to any differences.

                  (g) Except as set forth in the Registration Statement and
Prospectus (or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus), subsequent to the respective dates as of which
information is given in the Registration Statement and the Prospectus and prior
to the Closing Date and, if later, the Option Closing Date, (i) there has not
been, and will not have been, any material adverse change in the business,
properties, financial condition, net worth or results of operations of the
Company and its Subsidiaries considered as one enterprise, (ii) neither the
Company nor any of its Subsidiaries has entered into, or will have entered into
any material transactions other than pursuant to this Agreement, and (iii) the
Company has not, and will not have, paid or declared any dividends or other
distributions of any kind on any class of its capital stock, except for the
payment or declaration of quarterly dividends on the Company's common stock (the
"Common Stock") in the ordinary course of its business.

                  (h) The Company and each of its Subsidiaries have good and
marketable title to all properties and assets described in the Registration
Statement, including the documents incorporated by reference therein, and
Prospectus (or, if the Prospectus is not in existence, the most recent
Preliminary Prospectus), as owned by it, free and clear of all liens, security
interests, restrictions, pledges, encumbrances, charges, equities, claims,
easements, leases and tenancies (collectively, "Encumbrances") other than those
described in the Registration Statement, or in the documents incorporated by
reference therein, and Prospectus (or, if the Prospectus is not in existence,
the most recent Preliminary Prospectus) or those that will not materially affect
the value of such properties and assets or will not interfere with the use made
and proposed to be made of such properties and assets. The Company and each of
its Subsidiaries have valid, subsisting and enforceable leases for the
properties and assets described in the Registration Statement or in the
documents incorporated by reference therein, and Prospectus (or, if the
Prospectus is not in existence, the most recent Preliminary Prospectus) as
leased by them, free and clear of all Encumbrances, other than those described
in the Registration Statement or in the documents incorporated by reference
therein, and Prospectus (or, if the Prospectus is not in existence, the most


<PAGE>   7
                                        7


recent Preliminary Prospectus), or those that will not materially affect the
value of such properties and assets or will not interfere with the use made and
proposed to be made of such properties and assets.

                  (i) The Company is not required to be registered under the
Investment Company Act of 1940, as amended (the "Investment Company Act").

                  (j) Except as set forth in the Registration Statement, or
incorporated therein by reference, and Prospectus (or, if the Prospectus is not
in existence, the most recent Preliminary Prospectus), there are no actions,
suits, arbitrations, claims, governmental or other proceedings (formal or
informal), or investigations pending or threatened against or affecting the
Company or any of its Subsidiaries, or any directors, officers or shareholders
of the Company or any of its Subsidiaries in their respective capacities as
such, or any of the properties or assets owned or leased by the Company or any
of its Subsidiaries, before or by any Federal, state or Commonwealth of Puerto
Rico court, commission, regulatory body, administrative agency or other
governmental body, domestic or foreign (collectively, a "Governmental Body"),
wherein an unfavorable ruling, decision or finding would adversely affect the
business, prospects, financial condition, net worth or results of operations of
the Company and its Subsidiaries taken as a whole and would be required to be
disclosed in the Registration Statement and Prospectus (or if the Prospectus is
not in existence, in the most recent Preliminary Prospectus). Neither the
Company nor any Subsidiary is in violation of, or in default with respect to,
any law, rule, or regulation, or any order, judgment, or decree, except as
described in the Prospectus (or if the Prospectus is not in existence, in the
most recent Preliminary Prospectus) or such as in the aggregate do not now have
and can reasonably be expected in the future not to have a material adverse
effect upon the operations, business, properties, or assets of the Company and
its Subsidiaries taken as a whole; nor is the Company or any Subsidiary
presently required under any order, judgment or decree to take any action in
order to avoid any such violation or default.

                  (k) The Company and each of its Subsidiaries have and, at the
Closing Date and the Option Closing Date, will have all governmental licenses,
permits, consents, orders, approvals, franchises, certificates and other
authorizations (collectively, "Licenses") necessary to carry on their respective
businesses and own or lease their respective properties as contemplated in the
Registration Statement and Prospectus (or, if the Prospectus is not in
existence, the most recent Preliminary Prospectus). The Company and each of its
Subsidiaries have and, at the Closing Date and the Option Closing Date, will
have complied in all material respects with all laws, regulations and orders
applicable to it or its business, assets and properties. Neither the Company nor
any of its Subsidiaries is, nor, at the Closing Date and the Option Closing
Date, will be in default (nor has any event occurred which, with notice or lapse
of time or both, would constitute a default) in the due performance and
observation of any term, covenant or condition of any indenture, mortgage, deed
of trust, voting trust agreement, loan agreement, bond, debenture, note
agreement or other evidence of indebtedness, lease, contract or other agreement
or instrument (collectively, a "contract or other agreement") to which they are
a party or by which their respective properties are bound or affected,


<PAGE>   8
                                        8


the violation of which would individually or in the aggregate have a material
adverse effect on the condition, financial or otherwise, or the earnings,
prospects or business affairs of the Company and its Subsidiaries taken as a
whole. There are no governmental proceedings or actions pending or threatened
for the purpose of suspending, modifying or revoking any License held by the
Company and its Subsidiaries.

                  (l) No consent, approval, authorization or order of, or any
filing or declaration with, any Governmental Body is required for the
consummation of the transactions contemplated by this Agreement or in connection
with the issuance and sale of the Shares by the Company, except such as have
been obtained and such as may be required under state or Commonwealth of Puerto
Rico securities or blue sky laws or the bylaws and rules of the National
Association of Securities Dealers, Inc. (the "NASD") in connection with the
purchase and distribution by the Underwriters of the Shares to be sold hereby.

                  (m) The Company has full power (corporate and other) and
authority to enter into this Agreement and to carry out all the terms and
provisions hereof to be carried out by it. This Agreement has been duly
authorized, executed and delivered by the Company and constitutes a valid and
binding agreement of the Company and is enforceable against the Company in
accordance with the terms hereof, except as rights to indemnity and contribution
may be limited by federal, state or Commonwealth of Puerto Rico securities laws
or the public policy underlying such laws. Except as disclosed in the
Registration Statement and the Prospectus (or, if the Prospectus is not in
existence, the most recent Preliminary Prospectus), the execution, delivery and
the performance of this Agreement and the consummation of the transactions
contemplated hereby will not result in the creation or imposition of any
Encumbrance upon any of the properties or assets of the Company or any of the
Subsidiaries pursuant to the terms or provisions of, or result in a breach or
violation of or conflict with any of the terms or provisions of, or constitute a
default under, or give any other party a right to terminate any of its
obligations under, or result in the acceleration of any obligation under, (i)
the Certificate of Incorporation or By-laws of the Company, in each case as
amended, or (ii) any contract or other agreement to which the Company or any of
the Subsidiaries is a party or by which it or any of the respective assets or
properties are bound or affected, the violation of which would individually or
in the aggregate have a material adverse effect on the condition, financial or
otherwise, or the earnings, prospects or business affairs of the Company and its
Subsidiaries, or (iii) any judgment, ruling, decree, order, law, statute, rule
or regulation of any Governmental Body applicable to the Company or any of the
Subsidiaries or their respective businesses or properties, the violation of
which would individually or in the aggregate have a material adverse effect on
the financial condition, or the earnings, prospects or business affairs of the
Company and its Subsidiaries.

                  (n) No statement, representation, or warranty made by the
Company in this Agreement or made in any certificate or document required by
this Agreement to be delivered to the Representative was or will be, when made,
inaccurate, untrue or incorrect in any material respect. Each certificate signed
by an officer of the Company and delivered to the Representative or counsel

for the Underwriters shall be deemed to be a representation and warranty by the
Company to each Underwriter as to the matters covered thereby.

                  (o) Neither the Company nor any of its directors, officers or
affiliates has taken, nor will he, she or it take, directly or indirectly, any
action designed, or which might reasonably be expected in the future, to cause
or result in, under the Act or otherwise, or which has constituted,
stabilization or manipulation of the price of any security of the Company to
facilitate the sale or resale of the Shares or otherwise.

                  (p) The Shares have been approved for listing on the New York
Stock Exchange ("NYSE"), subject only to notice of issuance.

                  (q) Neither the Company nor any of its Subsidiaries is
involved in any collective labor dispute with its employees nor is any such
dispute threatened or imminent.

                  (r) Neither the Company nor any of its Subsidiaries nor, to
the Company's best knowledge, any employee or agent of the Company or any
Subsidiary has made any payment of funds of the Company or any Subsidiary or
received or retained any funds of the Company or any Subsidiary in violation of
any law, rule or regulation which payment, receipt or retention of funds is of a
character required to be disclosed in the Prospectus (or, if the Prospectus is
not in existence, in the most recent Preliminary Prospectus).

                  (s) The business, operations and facilities of the Company and
its Subsidiaries have been and are being conducted in compliance with all
applicable laws, ordinances, rules, regulations, licenses, permits, approvals,
plans, authorizations or requirements relating to occupational safety and
health, or pollution, or protection of health or the environment (including,
without limitation, those relating to emissions, discharges, releases or
threatened releases of pollutants, contaminants or hazardous or toxic
substances, materials or wastes into ambient air, surface water, groundwater or
land, or relating to the manufacture, processing, distribution, use, treatment
storage, disposal, transport or handling of chemical substances, pollutants,
contaminants or hazardous or toxic substances, materials or wastes, whether
solid, gaseous or liquid in nature) of any governmental department, commission,
board, bureau, agency or instrumentality of the United States, any state, or the
Commonwealth of Puerto Rico or political subdivision thereof, and all applicable
judicial or administrative agency or regulatory decrees, awards, judgments and
orders relating thereto; and neither the Company nor any of its Subsidiaries has
received any notice from any governmental instrumentality or any third party
alleging any violation thereof or liability thereunder (including, without
limitation, liability for costs of investigating or remediating sites containing
hazardous substances and/or damages to natural resources), except where failure
to so comply would not have a material adverse effect on the financial
condition, or the earnings or business affairs of the Company and its
Subsidiaries taken as a whole. The intended use and occupancy of each of the
facilities owned or operated by the Company and its Subsidiaries complies in all
material respects with all applicable codes and zoning laws and regulations, and
there is no


<PAGE>   10
                                       10


pending or threatened condemnation, zoning change, environmental or other
proceeding or action that will in any material respect adversely affect the size
of, use of, improvements on, construction on, or access to such facilities.

                  (t) The Company filed all foreign, federal, state and local
tax returns that are required to be filed or has requested extensions thereof
and has paid all taxes required to be paid by it and any other assessment, fine
or penalty levied against it, to the extent that any of the foregoing is due and
payable, except for any failure to file that would not have a material adverse
effect on the financial condition of the Company.

                  (u) The Company meets the requirements for use of Form S-3
under the Rules and Regulations.

                  (v) The deposit accounts of FirstBank Puerto Rico, a
Subsidiary of the Company ("FirstBank") are insured by the Savings Association
Insurance Fund ("SAIF") of the Federal Deposit Insurance Corporation ("FDIC") to
the legal maximum, and no proceeding for the termination or revocation of such
insurance is pending or threatened. FirstBank is a member in good standing of
the Federal Home Loan Bank of New York.

                  (w) None of the Company, FirstBank, their affiliates, or any
of their respective directors or officers is subject to any order or directive
of, or party to any agreement with, any regulatory agency having jurisdiction
with respect to its business or operations except as disclosed in the Prospectus
(or if the Prospectus is not in existence, in the most recent Preliminary
Prospectus).

         4.       Agreements of the Company. The Company covenants and agrees 
with each of the several Underwriters as follows:

                  (a) The Company will not, either prior to the Effective Date
or thereafter during such period as the Prospectus is required by law to be
delivered in connection with sales of the Shares by an Underwriter or dealer,
file any amendment or supplement to the Registration Statement or the
Prospectus, unless a copy thereof shall first have been submitted to the
Representative within a reasonable period of time prior to the filing thereof
and the Representative shall not have objected thereto in good faith.

                  (b) If the Registration Statement is not yet effective, the
Company will use its best efforts to cause the Registration Statement to become
effective not later than the time indicated in Section 6(a) hereof. The Company
will notify the Representative promptly, and will confirm such advice in
writing, (i) when the Registration Statement has become effective and when any
post-effective amendment thereto becomes effective, (ii) of any request by the
Commission for amendments or supplements to the Registration Statement or the
Prospectus or for additional information, (iii) of the issuance by the
Commission of any stop order suspending the effectiveness of the Registration
Statement or the initiation of any proceedings for that purpose or the threat
<PAGE>   11
                                       11

thereof, (iv) of the happening of any event during the period mentioned in the
first sentence of Section 4(g) that in the judgment of the Company makes any
statement of a material fact made in the Registration Statement or the
Prospectus untrue or that requires the making of any changes in the Registration
Statement or the Prospectus in order to make the statements therein, in light of
the circumstances in which they are made, not misleading, and (v) of receipt by
the Company or any representative or attorney of the Company of any other
communication from the Commission relating to the Company, the Registration
Statement, any Preliminary Prospectus or the Prospectus. If at any time the
Commission shall issue any order suspending the effectiveness of the
Registration Statement, the Company will make every reasonable effort to obtain
the withdrawal of such order at the earliest possible moment. The Company will
prepare the Prospectus in a form approved by the Representative and will file
such Prospectus pursuant to Rule 424(b) under the Act not later than the
Commission's close of business on the second business day following the
execution and delivery of this Agreement or, if applicable, such earlier time as
may be required by Rule 430A(a)(3) under the Act. If the Company has omitted any
information from the Registration Statement pursuant to Rule 430A, the Company
will use its best efforts to comply with the provisions of and make all
requisite filings with the Commission pursuant to said Rule 430A and to notify
the Representative promptly of all such filings.

                  (c) If the Company elects to rely upon Rule 462(b) of the
Rules and Regulations, the Company shall file the Rule 462(b) Registration
Statement with the Commission in compliance with Rule 462(b) of the Rules and
Regulations by 10:00 p.m., Washington, D.C. time, on the date of this Agreement,
and the Company shall at the time of filing, either pay to the Commission the
filing fee for the Rule 462(b) Registration Statement or give irrevocable
instructions for the payment of such fee pursuant to Rule 111(b) of the Rules
and Regulations.

                  (d) If, at any time when a Prospectus relating to the Shares
is required to be delivered under the Act, any event occurs as a result of
which, in the judgment of the Company or in the opinion of counsel for the
Underwriters, the Prospectus, as then amended or supplemented, would include any
untrue statement of a material fact or omit to state a material fact necessary
in order to make the statements therein, in the light of the circumstances under
which they were made, not misleading, or the Registration Statement, as then
amended or supplemented, would include any untrue statement of a material fact
or omit to state a material fact necessary to make the statements therein not
misleading, or if for any other reason it is necessary at any time to amend or
supplement the Prospectus or the Registration Statement to comply with the Act
or the Rules and Regulations, the Company will promptly notify the
Representative thereof and, subject to Section 4(b) hereof, will prepare and
file with the Commission, at the Company's expense, an amendment to the
Registration Statement or an amendment or supplement to the Prospectus that
corrects such statement or omission or effects such compliance.

                  (e) The Company will furnish to the Representative, without
charge, two signed copies of the Registration Statement and of any
post-effective amendment thereto, including financial statements and schedules,
and all exhibits thereto and will furnish to the Representative,
<PAGE>   12
                                       12


without charge, for transmittal to each of the other Underwriters, copies of the
Registration Statement and any post-effective amendment thereto, including
financial statements and schedules but without exhibits.

                  (f) The Company will comply with all the provisions of all
undertakings contained in the Registration Statement.

                  (g) On the Effective Date, and thereafter from time to time
for such period as the Prospectus is required by the Act to be delivered, the
Company will deliver to each of the Underwriters, without charge, as many copies
of the Prospectus or any amendment or supplement thereto as the Representative
may reasonably request. The Company consents to the use of the Prospectus or any
amendment or supplement thereto by the several Underwriters and by all dealers
to whom the Shares may be sold, both in connection with the offering or sale of
the Shares and for any period of time thereafter during which the Prospectus is
required by law to be delivered in connection therewith. If during such period
of time any event shall occur which in the judgment of the Company or counsel to
the Underwriters should be set forth in the Prospectus in order to make any
statement therein, in the light of the circumstances under which it was made,
not misleading, or in the Registration Statement in order to make any statement
therein not misleading, or if it is necessary to supplement or amend the
Prospectus or the Registration Statement to comply with law, the Company will
forthwith prepare and duly file with the Commission an appropriate supplement or
amendment thereto, and deliver to each of the Underwriters, without charge, such
number of copies thereof as the Representative may reasonably request.

                  (h) Prior to any public offering of the Shares by the
Underwriters, the Company will cooperate with the Representative and its counsel
in connection with the registration or qualification of the Shares for offer and
sale under the securities or blue sky laws of such jurisdictions as the
Representative may reasonably request; provided, that in no event shall the
Company be obligated to qualify to do business in any jurisdiction where it is
not now so qualified or to take any action which would subject it to general
service of process in any jurisdiction where it is not now so subject.

                  (i) During the period of five years commencing on the
Effective Date, the Company will furnish to the Representative and each other
Underwriter who may so request copies of such financial statements and other
periodic and special reports as the Company may from time to time distribute
generally to the holders of any class of its capital stock, and will furnish to
the Representative and each other Underwriter who may so request a copy of each
annual or other report it shall be required to file with the Commission.

                  (j) The Company will make generally available to holders of
its securities, as soon as may be practicable, but in no event later than the
last day of the fifteenth full calendar month following the calendar quarter in
which the Effective Date falls, a consolidated earnings statement (which need
not be audited but shall be in reasonable detail) for a period of 12 months
commencing
<PAGE>   13
                                       13


after the Effective Date, and satisfying the provisions of Section 11(a) of the
Act (including Rule 158 of the Rules and Regulations).

                  (k) The Company will apply the net proceeds from the offering
and sale of the Shares in the manner set forth in the Prospectus under "Use of
Proceeds."

                  (l) The Company will not at any time, directly or indirectly,
take any action intended, or which might reasonably be expected, to cause or
result in, or which will constitute, stabilization of the price of the shares of
Preferred Stock to facilitate the sale or resale of any of the Shares.

         5.       Expenses.

                  (a) Whether or not the transactions contemplated by this
Agreement are consummated or this Agreement is terminated, the Company will pay,

                  (f)      The Representative shall have received an opinion, 
dated the Closing Date and the Option Closing Date, from Fiddler Gonzalez &
Rodriguez, LLP, Puerto Rico counsel for the Company to the following effect:

                           (i) The Company has been duly organized and validly
                  existing as a corporation under the laws of the Commonwealth
                  of Puerto Rico and is in good standing with the Commonwealth
                  of Puerto Rico. Each of First Federal Finance Corporation
                  ("First Federal"), First Leasing & Rental Corporation ("First
                  Leasing") and FirstBank, each a Subsidiary, is a corporation
                  duly organized, validly existing and in good standing under
                  the laws of its respective jurisdiction of incorporation. Each
                  of the Company, First Federal, First Leasing and FirstBank is
                  duly qualified and in good standing as a foreign corporation
                  in each jurisdiction in which the character or location of its
                  properties (owned, leased or licensed) or the nature or
                  conduct of its business or use of its property and assets
                  makes such qualification necessary, except where the failure
                  to so qualify would not have a material adverse effect on the
                  financial condition, or the earnings or business affairs of
                  the Company and its Subsidiaries taken as a whole;

                           (ii) The Company has an authorized capitalization as
                  set forth in the Prospectus; the Company has duly authorized
                  the issuance and sale of the Shares to be sold by it
                  hereunder; such Shares, when issued by the Company and paid
                  for in accordance with the terms hereof, will be validly
                  issued, fully paid and nonassessable and will conform in all
                  material respects to the description thereof contained in the
                  Prospectus and will not be subject to any preemptive,
                  subscription or other similar rights; the Shares have been
                  duly authorized for listing on the NYSE, subject only to
                  official notice of issuance; and no holders of securities of
                  the Company are entitled to have such securities registered
                  under the Registration Statement, except for holders who have
                  waived any such registration rights;

                           (iii) The Registration Statement, including any Rule
                  462(b) Registration Statement, is effective under the Act; any
                  required filing of the Prospectus pursuant to Rule 424(b) has
                  been made in the manner and within the time period required by
                  Rule 424(b); and to the best knowledge of such counsel, no
                  stop order suspending the effectiveness of the Registration
                  Statement or any amendment thereto and no order directed at
                  any document incorporated by reference in the Registration
                  Statement or of the Rule 462(b) Registration Statement or any
                  amendment thereto has been issued, and, no proceedings for
                  that purpose have been instituted or are pending or are
                  threatened or contemplated under the Act;
<PAGE>   16
                                       16


                           (iv) The Registration Statement and the Prospectus as
                  of its date, appeared on their face to be appropriately
                  responsive, in all material respects (other than the documents
                  incorporated therein by reference and not including the
                  financial statements, schedules and other financial data
                  contained therein, as to which such counsel need not express
                  any opinion), with the requirements of the Act and the related
                  rules and regulations thereunder;

                           (v) The descriptions contained and summarized in the
                  Registration Statement, or incorporated therein by reference,
                  and the Prospectus are accurate and fairly represent in all
                  material respects the information required to be shown in the
                  Registration Statement and Prospectus by the Act and the Rules
                  and Regulations; and the statements set forth under the
                  headings "Risk Factors - Banking Regulations May Restrict
                  First BanCorp's Ability to Pay Dividends," "Recent
                  Developments," "Description of Capital Stock," and "Taxation"
                  in the Prospectus, insofar as such statements constitute a
                  summary of the legal matters, documents or proceedings
                  referred to therein, provide an accurate summary of such legal
                  matters, documents and proceedings;

                           (vi) To the knowledge of such counsel, there are no
                  contracts or documents which are required by the Act to be
                  described in the Registration Statement or the Prospectus or
                  to be filed as exhibits to the Registration Statement which
                  are not filed or incorporated therein by reference as required
                  by the Act and the Rules and Regulations;

                           (vii) To the knowledge of such counsel after
                  reasonable investigation, there is not pending or threatened
                  against the Company or any of the Subsidiaries any legal
                  action or proceeding, suit, arbitration, claim, or
                  governmental or other proceeding (informal or formal) or
                  investigation before or by any Governmental Body, of a
                  character required to be disclosed in the Registration
                  Statement or the Prospectus which is not so disclosed therein
                  or in the materials incorporated by reference therein, and to
                  the knowledge of such counsel, no such proceedings have been
                  threatened against the Company or any of its Subsidiaries or
                  any of their respective assets or properties. To the knowledge
                  of such counsel after reasonable investigation, neither the
                  Company nor any Subsidiary is in violation of, or in default
                  with respect to, any law, rule, or regulation, or any order,
                  judgment or decree, except as described in the Registration
                  Statement or Prospectus or in the materials incorporated by
                  reference therein, or such as in the aggregate do not now have
                  and can reasonably be expected in the future not to have a
                  material adverse effect upon the operations, business,
                  properties, or assets of the Company and its Subsidiaries
                  taken as a whole; nor is the Company or any Subsidiary
                  presently required under any order, judgment or decree to take
                  any action in order to avoid any such violation or default;

                                       17


                           (viii) The Company has full legal right, power, and
                  authority to enter into this Agreement and to consummate the
                  transactions provided for herein; this Agreement has been duly
                  authorized, executed and delivered by the Company; this
                  Agreement, assuming due authorization, execution and delivery
                  by each other party hereto, is a valid and binding agreement
                  of the Company, except as limited by applicable bankruptcy,
                  insolvency, reorganization, moratorium or other laws now or
                  hereafter in effect relating to or affecting creditors' rights
                  generally or by general principles of equity relating to the
                  availability of remedies and except as rights to indemnity and
                  contribution may be limited by federal, state, or Commonwealth
                  of Puerto Rico securities laws or the public policy underlying
                  such laws;

                           (ix) None of the Company's execution or delivery of
                  this Agreement, its performance hereof, its consummation of
                  the transactions contemplated herein or its application of the
                  net proceeds of the offering in the manner set forth under the
                  caption "Use of Proceeds," conflicts or will conflict with or
                  results or will result in any breach or violation of any of
                  the terms or provisions of, or constitute a default under, or
                  result in the creation or imposition of any Encumbrance upon,
                  any property or assets of the Company pursuant to (A) the
                  terms of the Certificate of Incorporation or By-laws of the
                  Company, in each case as amended; (B) the terms of any
                  contract or other agreement to which the Company is a party or
                  by which it is or may be bound or to which any of its
                  properties is or may be subject and of which such counsel has
                  knowledge; (C) any statute, rule or regulation of any
                  Governmental Body having jurisdiction over the Company or any
                  of its activities or properties; or (D) the terms of any
                  judgment, decree or order of any arbitrator or Governmental
                  Body having such jurisdiction and of which such counsel has
                  knowledge; and no consent, approval, authorization or order of
                  any Governmental Body has been or is required for the
                  Company's performance of this Agreement or the consummation of
                  the transactions contemplated hereby, except such as have been
                  obtained under the Act or may be required under state or
                  Commonwealth of Puerto Rico securities or blue sky laws in
                  connection with the purchase and distribution by the
                  Underwriters of the Shares;

                           (x) To such counsel's knowledge, the conduct of the
                  respective businesses of the Company and its Subsidiaries is
                  not in violation of any federal, state or local statute,
                  administrative regulation or other law, which violation is
                  likely to have a material adverse effect on the Company and
                  its Subsidiaries taken as a whole; and the Company and its
                  Subsidiaries have obtained all material licenses as are
                  necessary or required for the conduct of their businesses as
                  presently conducted;

                           (xi) The Company is not required to be registered as
                  an investment company under the Investment Company Act;
<PAGE>   18
                                       18


                           (xii) To the knowledge of such counsel, the Company
                  is not in any breach or violation of any of the terms or
                  provisions of, or in default under (nor has an event occurred
                  which with notice or lapse of time or both would constitute a
                  default or acceleration under), (A) the terms of its
                  Certificate of Incorporation or By-laws, in each case as
                  amended; (B) the terms of any contract or other agreement
                  known to such counsel after reasonable investigation to which
                  the Company is a party or by which the Company is or may be
                  bound or to which any of its properties or assets is or may be
                  subject, which breach, violation or default could have a
                  material adverse effect on the Company and its Subsidiaries
                  taken as a whole; (C) any statute, rule or regulation of any
                  Governmental Body having jurisdiction over the Company or any
                  of its activities, assets or properties, which breach,
                  violation or default could have a material adverse effect on
                  the Company and its Subsidiaries taken as a whole; or (D) the
                  terms of any judgment, decree or order, known to such counsel
                  after reasonable investigation, of any arbitrator or
                  Governmental Body having such jurisdiction, which breach,
                  violation or default could have a material adverse effect on
                  the Company and its Subsidiaries taken as a whole;

                           (xiii) The deposit accounts of FirstBank are insured
                  by the SAIF of the FDIC to the legal maximum, and to such
                  counsel's knowledge no proceeding for the termination or
                  revocation of such insurance is pending or threatened.
                  FirstBank is a member in good standing of the Federal Home
                  Loan Bank of New York; and

                           (xiv) To the knowledge of such counsel, none of the
                  Company or any of its Subsidiaries, or any of their respective
                  directors or officers is subject to any order or directive of,
                  or party to any agreement with, any regulatory agency having
                  jurisdiction with respect to the business or operations of the
                  Company or any of its Subsidiaries, except as disclosed in the
                  Registration Statement or the Prospectus or in the materials
                  incorporated by reference therein.

                  In addition, such counsel shall state that in the course of
the preparation of the Registration Statement and the Prospectus, such counsel
has participated in conferences with officers and representatives of the Company
and with the Accountants, at which conferences such counsel made inquiries of
such officers, representatives and Accountants and discussed the contents of the
Registration Statement and the Prospectus and, on the basis of the foregoing
nothing has come to such counsel's attention that causes such counsel to believe
that the Registration Statement as of the date it was declared effective and as
of the Closing Date contained any untrue statement of a material fact or omitted
to state a material fact required to be stated therein or necessary to make the
statements therein not misleading or that the Prospectus as of the date thereof
and as of the Closing Date, contained any untrue statement of a material fact or
omitted or omits to state a material fact required to be stated therein or
necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading (it being understood that such
counsel need not express any opinion with respect to the financial statements,
schedules and other financial
<PAGE>   19
                                       19


data included in the Registration Statement or the Prospectus). Such counsel may
state that they make no representation that they have independently verified the
accuracy or completeness of the statements contained in the Registration
Statement and Prospectus.

                  In rendering any such opinion, such counsel may rely, as to
matters of fact, to the extent such counsel deems proper, on certificates of
responsible officers of the Company and public officials and, as to matters
involving the application of laws of any other jurisdiction than the
Commonwealth of Puerto Rico and the United States (to the extent satisfactory in
form and scope to counsel for the Underwriters) such counsel may rely upon the
opinion of local (including in-house) counsel to the Company. The foregoing
opinion shall also state that such counsel has no reason to believe that the
Underwriters are not justified in relying upon such opinion of local counsel,
and copies of such opinion shall be delivered to the Representative and its
counsel.

                  References to the Registration Statement and the Prospectus in
this paragraph (f) shall include any amendment or supplement thereto at the date
of such opinion.

                  (g)      The Representative shall have received an opinion, 
dated the Closing Date and the Option Closing Date, from Axtmayer Adsuar Muniz &
Goyco, P.S.C., counsel to the Underwriters, which opinion shall be satisfactory
in all respects to the Representative.

                  (h)      Concurrently with the execution and delivery of this
Agreement, or, if the Company elects to rely on Rule 430A, on the date of the
Prospectus, the Accountants shall have furnished to the Representative a letter,
dated the date of its delivery (the "Original Letter"), addressed to the
Representative and in form and substance satisfactory to the Representative, to
the effect that:

                           (i) they are independent accountants within the
                  meaning of the Act and the applicable published rules and
                  regulations thereunder;

                           (ii) in their opinion, the consolidated financial

                  published rules and regulations thereunder with respect to

                  consisting of (a) reading the minutes of meetings of the
                  stockholders and the Board of Directors of the Company and its

                  minute books through a specified date not more than five
                  business days prior to the date of delivery of the Original
                  Letter; (b) performing the procedures specified by the

                  71, "Interim Financial Information," on the unaudited
                  consolidated interim financial statements of the Company and
                  its Subsidiaries included in the Registration Statement and
                  reading the unaudited interim financial data for the period
                  from the date of the latest balance sheet incorporated by
                  reference in the Registration Statement to the date of the
                  latest available interim financial data; and (c) making
                  inquiries of certain officials of the Company who have
                  responsibility for financial and accounting matters regarding
                  the specific items for which representations are requested
                  below; nothing has come to their attention (as of a date not
                  more than five business days prior to the date of the delivery
                  of such letter) as a result of the foregoing procedures that
                  caused them to believe that: (1) the unaudited consolidated
                  interim financial statements, if any, incorporated by
                  reference in the Registration Statement, do not comply as to
                  form in all material respects with the applicable accounting
                  requirements of the Exchange Act and the published rules and
                  regulations thereunder; (2) any material modifications should
                  be made to the unaudited consolidated interim financial
                  statements, if any, incorporated by reference in the
                  Registration Statement, for them to be in conformity with
                  generally accepted accounting principles; (3) (i) at the date
                  of the latest available interim financial data and at a
                  specified date not more than five business days prior to the
                  date of delivery of the Original Letter there was any change
                  in the capital stock, deposits, federal funds purchased or
                  securities sold under agreements to repurchase or any
                  decreases in the consolidated stockholders' equity (only as to
                  the latest interim financial data) of the Company and its
                  Subsidiaries as compared with amounts shown in the December
                  31, 1998 balance sheet incorporated by reference in the
                  Registration Statement and (ii) for the period from January 1,
                  1999, to the latest interim financial data available which
                  should be no later than forty (40) days prior to the date of
                  delivery of the Original Letter, there were any decreases, as
                  compared with the corresponding period in the preceding year,
                  in consolidated net interest income, other income, income
                  before taxes or in the total or per share amounts of net
                  income, except in all instances for changes or decreases which
                  the Registration Statement discloses have occurred or may
                  occur, or they shall state any specific changes or decreases;
                  and

                           (iv) the information set forth under the captions
                  "Prospectus Summary Summary Financial and Other Data,"
                  "Prospectus Summary - Consolidated Ratio of Earnings to
                  Combined Fixed Charges and Preferred Stock Dividends," "Recent
                  Developments," "Capitalization," "Selected Financial Data,"
                  and "Description of Capital Stock," which is expressed in
                  dollars (or percentages derived from such dollar amounts) and
                  has been obtained from accounting records which are subject to
                  the internal controls of the Company's accounting system or
                  which has been derived directly from such accounting records
                  and analysis or computations, is in agreement with such
                  records or computations made therefrom.

                  At the Closing Date and, as to the Option Shares, the Option
Closing Date, the Accountants shall have furnished to the Representative a
letter, dated the date of its delivery, which shall confirm, on the basis of a
review in accordance with the procedures set forth in the Original Letter, that
nothing has come to their attention during the period from the date of the
Original Letter referred to in the prior sentence to a date (specified in the
letter) not more than five business days prior to the Closing Date or the Option
Closing Date, as the case may be, which would require any change in the Original
Letter if it were required to be dated and delivered at the Closing Date or the
Option Closing Date, as the case may be.

                  In the event that the letters referred to above set forth any
such changes, decreases or increases, it shall be a further condition to the
obligations of the Underwriters that (A) such letters shall be accompanied by a
written explanation of the Company as to the significance thereof, unless the
Representative deems such explanation unnecessary, and (B) such changes,
decreases or increases do not, in the sole judgment of the Representative, make
it impractical or inadvisable to proceed with the purchase and delivery of the
Shares as contemplated by the Registration Statement, as amended as of the date
hereof.

                  (i)      At the Closing Date and, as to the Option Shares, the
Option Closing Date, there shall be furnished to the Representative an accurate
certificate, dated the date of its delivery, signed by each of the Chief
Executive Officer and the Chief Financial Officer of the Company, in form and
substance satisfactory to the Representative, to the effect that to the best of
their knowledge:

                           (i) Each signer of such certificate has carefully
                  examined the Registration Statement and the Prospectus and (A)
                  as of the date of such certificate, (x) the Registration
                  Statement does not contain any untrue statement of a material
                  fact or omit to state a material fact required to be stated
                  therein or necessary in order to make the statements therein
                  not misleading and (y) the Prospectus does not contain any
                  untrue statement of a material fact or omit to state a
                  material fact required to be stated therein or necessary in
                  order to make the statements therein, in light of the
                  circumstances under which they were made, not misleading and
                  (B) since the Effective Date no event has occurred as a result
                  of which it is necessary to amend or supplement the Prospectus
                  in order to make the statements therein not untrue or
                  misleading in any material respect;

                           (ii) Each of the representations and warranties of
                  the Company contained in this Agreement were, when originally
                  made, and are, at the time such certificate is delivered, true
                  and correct in all respects; each of the covenants required
                  herein to be performed by the Company on or prior to the date
                  of such certificate has been duly, timely and fully performed
                  and each condition herein required to be complied with by the
                  Company on or prior to the delivery of such certificate has
                  been duly, timely and fully complied with.

                           (iii) No stop order suspending the effectiveness of
                  the Registration Statement or any post-effective amendment
                  thereto and no order directed at any document incorporated by
                  reference in the Registration Statement or any amendment
                  thereto or the Prospectus has been issued, and no proceedings
                  for that purpose have been instituted or threatened or, to the
                  best of the Company's knowledge, are contemplated by the
                  Commission.

                  (j)      The Shares shall be qualified for sale in such states
and possessions as the Representative may reasonably request, each such
qualification shall be in effect and not subject to any stop order or other
proceeding on the Closing Date and the Option Closing Date.

                  (k)      Prior to the Closing Date, the Shares shall have been
accepted for listing on the NYSE, subject only to official notice of issuance.

                  (l)      The Company shall have furnished to the 
Representative such certificates, letters and other documents, in addition to
those specifically mentioned herein, as the Representative may have reasonably
requested as to the accuracy and completeness at the Closing Date and the Option
Closing Date of any statement in the Registration Statement or the Prospectus,
as to the accuracy at the Closing Date and the Option Closing Date of the
representations and warranties of the Company, as to the performance by the
Company of its obligations hereunder, or as to the fulfillment of the conditions
concurrent and precedent to the obligations hereunder of the Underwriters.

                  All such opinions, certificates, letters and other documents
will be in compliance with the provisions hereof only if they are satisfactory
in form and substance to you. The Company will furnish you with such conformed
copies of such opinions, certificates, letters and other documents as you shall
reasonably request.

         7.       Indemnification and Contribution.

                  (a) The Company agrees to indemnify and hold harmless each
Underwriter, the directors, officers, employees and agents of each Underwriter
and each person, if any, who controls each Underwriter within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act, from and against any
and all losses, claims, damages or liabilities, joint or several (and actions in
respect thereof), to which they, or any of them, may become subject under the
Act or other Federal, state or Commonwealth of Puerto Rico statutory law or
regulation, at common law or otherwise, insofar as such losses, claims, damages
or liabilities (or actions in respect thereof) arise out of or are based upon
(i) any untrue statement or alleged untrue statement made by the Company in
Section 3 of this Agreement, (ii) any untrue statement or alleged untrue
statement of any material fact contained in (A) any Preliminary Prospectus, the
Registration Statement or the Prospectus or any amendment or supplement to the
Registration Statement or the Prospectus or (B) any application or other
document, or any amendment or supplement thereto, executed by the Company or
based upon
<PAGE>   23
                                       23

written information furnished by or on behalf of the Company filed in any
jurisdiction in order to qualify the Shares under the securities or blue sky
laws thereof or filed with the Commission or any securities association or
securities exchange (each, an "Application"), or (iii) the omission or alleged
omission to state in any Preliminary Prospectus, the Registration Statement or
the Prospectus or any amendment or supplement to the Registration Statement or
the Prospectus or any Application a material fact required to be stated therein
or necessary to make the statements therein not misleading, and will reimburse,
as incurred, each Underwriter and each such other person for any legal or other
expenses reasonably incurred by such Underwriter or such other person in
connection with investigating defending or appearing as a third-party witness in
connection with any such loss, claim, damage, liability or action; provided,
however, that the Company will not be liable in any such case to the extent that
any such loss, claim, damage or liability based solely upon an untrue statement
or omission or alleged untrue statement or omission in any of such documents
made in reliance upon and in conformity with information relating to any
Underwriter furnished in writing to the Company by the Representative on behalf
of any Underwriter expressly for inclusion therein; Provided, further, that such
indemnity with respect to any Preliminary Prospectus shall not inure to the
benefit of any Underwriter (or any such other person) from whom the person
asserting any such loss, claim, damage, liability or action purchased Shares
which are the subject thereof to the extent that any such loss, claim, damage or
liability (i) results from the fact that such Underwriter failed to send or give
a copy of the Prospectus (as amended or supplemented) to such person at or prior
to the confirmation of the sale of such Shares to such person in any case where
such delivery is required by the Act and (ii) arises out of or is based upon an
untrue statement or omission of a material fact contained in such Preliminary
Prospectus that was corrected in the Prospectus (or any amendment or supplement
thereto), unless such failure to deliver the Prospectus (as amended or
supplemented) was the result of noncompliance by the Company with Section 4(g).
This indemnity agreement will be in addition to any liability that the Company
might otherwise have. The Company will not, without the prior written consent of
each Underwriter, settle or compromise or consent to the entry of any judgment
in any pending or threatened claim, action, suit or proceeding in respect of
which indemnification may be sought hereunder (whether or not such Underwriter
or any person who controls such Underwriter within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act is a party to each claim, action, suit
or proceeding), unless such settlement, compromise or consent includes an
unconditional release of each Underwriter and each such other person from all
liability arising out of such claim, action, suit or proceeding.

                  (b) Each Underwriter will indemnify and hold harmless the
Company, and each person, if any, who controls the Company within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act, each director of the
Company and each officer of the Company who signed the Registration Statement
against any losses, claims, damages or liabilities (or actions in respect
thereof) to which the Company and any such director, officer or controlling
person may become subject under the Act or other federal, state or Commonwealth
of Puerto Rico statutory law or regulation, at common law or otherwise, insofar
as such losses, claims, damages or liabilities (or actions in respect thereof)
arise out of or are based upon (i) any untrue statement or alleged untrue
statement of a material fact contained in any Preliminary Prospectus, the
Registration Statement or
<PAGE>   24
                                       24

the Prospectus or any amendment or supplement to the Registration Statement or
the Prospectus or any Application, or material fact required to be stated
therein or (ii) the omission or the alleged omission to state in the
Registration Statement, any Preliminary Prospectus or the Prospectus or any
amendment or supplement to the Registration Statement or the Prospectus, or any
Application, a material fact required to be stated therein or necessary to make
the statements therein not misleading, in each case to the extent, but only to
the extent, that such untrue statement or alleged untrue statement or omission
or alleged omission was made in reliance upon and in conformity with written
information furnished to the Company by such Underwriter through the
Representative expressly for use therein; and, subject to the limitation set
forth immediately preceding this clause, will reimburse, as incurred, any legal
or other expenses reasonably incurred by the Company and any such director,
officer or controlling person in connection with investigating or defending any
such loss, claim, damage, liability or any action in respect thereof. The
Company acknowledges that, for all purposes under this Agreement, the statements
set forth under the heading "Underwriting" constitute the only information
relating to any Underwriter furnished in writing to the Company by the
Representative on behalf of the Underwriters expressly for inclusion in the
Registration Statement, any Preliminary Prospectus or the Prospectus. This
indemnity agreement will be in addition to any liability that each Underwriter
might otherwise have.

                  (c) Promptly after receipt by an indemnified party under this
Section 7 of notice of the commencement of any action, such indemnified party
will, if a claim in respect thereof is to be made against an indemnifying party
or parties under this Section 7, notify such indemnifying party or parties of
the commencement thereof, but the omission so to notify the indemnifying party
or parties will not relieve it or them from any liability which it or they may
have to any indemnified party under the foregoing provisions of this Section 7
or otherwise unless, and only to the extent that, such omission results in the
forfeiture of substantive rights or defenses by the indemnifying party. If any
such action is brought against an indemnified party and it notifies an
indemnifying party or parties of its commencement, the indemnifying party or
parties against which a claim is made will be entitled to participate therein
and, to the extent that it or they may wish, to assume the defense thereof with
counsel reasonably satisfactory to such indemnified party; provided, however,
that if the defendants in any such action include both the indemnified party and
the indemnifying party and the indemnified party shall have reasonably concluded
that there may be one or more legal defenses available to it and/or other
indemnified parties which are different from or additional to those available to
the indemnifying party, the indemnifying party shall not have the right to
direct the defense of such action on behalf of such indemnified party or parties
and such indemnified party or parties shall have the right to select separate
counsel to defend such action on behalf of such indemnified party or parties.
After notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof and approval by such indemnified party
of counsel appointed to defend such action, the indemnifying party will not be
liable to such indemnified party under this Section 7 for any legal or other
expenses other than reasonable costs of investigation subsequently incurred by
such indemnified party in connection with the defense thereof, unless (i) the
indemnified party shall have employed separate counsel in accordance with the
proviso to the next preceding sentence (it being understood, however, that in
connection with such action the
<PAGE>   25
                                       25


indemnifying party shall not be liable for the reasonable fees and expenses of
more than one separate counsel (in addition to the fees and expenses of local
counsel necessary in connection with any such proceedings) in any one action or
separate but substantially similar actions in the same jurisdiction arising out
of the same general allegations or circumstances, designated by the
Representative in the case of paragraph (a) of this Section 7, representing the
indemnified parties under paragraph (a) who are parties to such action or
actions), or (ii) the indemnifying party has authorized in writing the
employment of counsel for the indemnified party at the expense of the
indemnifying party. After such notice from the indemnifying party to such
indemnified party, the indemnifying party will not be liable for the costs and
expenses of any settlement of such action effected by such indemnified party
without the written consent of the indemnifying party, unless such indemnified
party waived its rights under this Section 7 in which case the indemnified party
may effect such a settlement without such consent.

                  (d) If the indemnification provided for in the foregoing
paragraphs of this Section 7 is unavailable or insufficient to hold harmless an
indemnified party under paragraph (a) or (b) above in respect of any losses,
claims, damages or liabilities (or actions in respect thereof) referred to
therein, then each indemnifying party shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages or
liabilities (or actions in respect thereof) (i) in such proportion as is
appropriate to reflect the relative benefits received by the indemnifying party
or parties, on the one hand, and the indemnified party, on the other, from the
offering of the Shares or (ii) if, but only if, the allocation provided by the
foregoing clause (i) is not permitted by applicable law, in such proportion as
is appropriate to reflect not only the relative benefits referred to in clause
(i) above but also the relative fault of the indemnifying party or parties on
the one hand, and the indemnified party, on the other, in connection with the
statements or omissions or alleged statements or omissions that resulted in such
losses, claims, damages or liabilities (or actions in respect thereof), as well
as any other relevant equitable considerations. The relative benefits received
by the Company, on the one hand, and the Underwriters, on the other, shall be
deemed to be in the same proportion as the total proceeds from the offering of
the Shares (before deducting expenses) received by the Company bear to the total
underwriting discounts and commissions received by the Underwriters, in each
case as set forth in the table on the cover page of the Prospectus. Relative
fault shall be determined by reference to whether the untrue or alleged untrue
statement of a material fact or the omission or alleged omission to state a
material fact relates to information supplied by the Company or the
Representative on behalf of the Underwriters, the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission. The Company and the Underwriters agree that it would not
be just and equitable if contributions pursuant to this Section 7(d) were to be
determined by pro rata allocation (even if the Underwriters were treated as one
entity for such purpose) or by any other method of allocation which does not
take into account the equitable considerations referred to herein. The amount
paid or payable by an indemnified party as a result of the losses, claims,
damages, liabilities (or actions in respect thereof) referred to above in this
Section 7(d) shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such action or claim. Notwithstanding the provisions of this Section
<PAGE>   26
                                       26


7(d), no Underwriter shall be required to contribute any amount in excess of the
total underwriting discounts received by it with respect to the Shares purchased
by such Underwriter under this Agreement, less the aggregate amount of any
damages that such Underwriter has otherwise been required to pay in respect of
the same or any substantially similar claim. No person found guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act)
will be entitled to contribution from any person who was not guilty of such
fraudulent misrepresentation. The Underwriters' obligations to contribute as
provided in this Section 7(d) are several in proportion to their respective
underwriting obligations and not joint. For purposes of this Section 7(d), each
person, if any, who controls an Underwriter within the meaning of Section 15 of
the Act or Section 20 of the Exchange Act will have the same rights to
contribution as such Underwriter, and each director of the Company, each officer
of the Company who signed the Registration Statement and each person, if any,
who controls the Company within the meaning of Section 15 of the Act or Section
20 of the Exchange Act, will have the same rights to contribution as the
Company, subject in each case to the provisions of this paragraph (d). Any party
entitled to contribution will, promptly after receipt of notice of commencement
of any action, suit or proceeding against such party in respect of which a claim
for contribution may be made under this Section 7(d), notify any such party or
parties from whom contribution may be sought, but the omission so to notify will
not relieve the party or parties from whom contribution may be sought from any
other obligation(s) it or they may have hereunder or otherwise than under this
paragraph (d) or to the extent that such party or parties were not adversely
affected by such omission. The contribution agreement set forth above shall be
in addition to any liabilities which any indemnifying party may otherwise have.
No party will be liable for contribution with respect to any action or claim
settled without its written consent (which consent will not be unreasonably
withheld).

                  (e) The indemnity and contribution agreements contained in
this Section 7 and the representations and warranties of the Company contained
in this Agreement shall remain operative and in full force and effect regardless
of (i) any investigation made by or on behalf of the Underwriters, (ii)
acceptance of any of the Shares and payment therefor or (iii) any termination of
this Agreement.

         8. Termination. The obligations of the several Underwriters under this
Agreement may be terminated at any time prior to the Closing Date (or, with
respect to the Option Shares, on or prior to the Option Closing Date), by notice
to the Company from the Representative, without liability on the part of any
Underwriter to the Company if, prior to delivery and payment for the Firm Shares
(or the Option Shares, as the case may be), in the sole judgment of the
Representative, (i) trading in the Common Stock or the Preferred Stock or
securities generally shall have been suspended by the Commission or by the NYSE,
(ii) minimum or maximum prices shall have been established for the Common Stock
or the Preferred Stock or securities generally on the NYSE, or additional
material governmental restrictions, not in force on the date of this Agreement,
shall have been imposed upon trading in securities generally by any of such

authorities, or (iv)

any material adverse change in the financial or securities markets in the United
States or any outbreak or material escalation of hostilities or declaration by
the United States of a national emergency or war or other calamity or crisis
shall have occurred, the effect of any of which is such as to make it, in the
sole judgment of the Representative, impracticable or inadvisable to market the
Shares on the terms and in the manner contemplated by the Prospectus. Any
termination pursuant to Section 8 shall be without liability of any party to any
other party except as provided in Sections 5(a) and 7.

         9. Default of Underwriters. If one or more Underwriters default in
their obligations to purchase Firm Shares or Option Shares hereunder and the
aggregate number of such Shares that such defaulting Underwriter or Underwriters
agreed but failed to purchase is ten percent or less of the aggregate number of
Firm Shares or Option Shares to be purchased by all of the Underwriters at such
time hereunder, the other Underwriters may make arrangements satisfactory to the
Representative for the purchase of such Shares by other persons (who may include
one or more of the nondefaulting Underwriters, including the Representative),
but if no such arrangements are made by the Closing Date or the related Option
Closing Date, as the case may be, the other Underwriters shall be obligated
severally in proportion to their respective commitments hereunder to purchase
the Firm Shares or Option Shares that such defaulting Underwriter or
Underwriters agreed but failed to purchase. If one or more Underwriters so
default with respect to an aggregate number of Shares that is more than ten
percent of the aggregate number of Firm Shares or Option Shares, as the case may
be, to be purchased by all of the Underwriters at such time hereunder, and if
arrangements satisfactory to the Representative are not made within 36 hours
after such default for the purchase by other persons (who may include one or
more of the nondefaulting Underwriters, including the Representative) of the
Shares with respect to which such default occurs, this Agreement will terminate
without liability on the part of any nondefaulting Underwriter and the Company
other than as provided in Section 10 hereof. In the event of any default by one
or more Underwriters as described in this Section 9, the Representative shall
have the right to postpone the Closing Date or the Option Closing Date, as the
case may be, established as provided in Section 9 hereof for not more than seven
business days in order that any necessary changes may be made in the
arrangements or documents for the purchase and delivery of the Firm Shares or
Option Shares, as the case may be. As used in this Agreement, the term
"Underwriter" includes any person substituted for an Underwriter under this
Section 9. Nothing herein shall relieve any defaulting Underwriter from
liability for its default.

         10. Survival. The respective representations, warranties, agreements,
covenants, indemnities and other statements of the Company, its officers, and
the several Underwriters set forth in this Agreement or made by or on behalf of
them, respectively, pursuant to this Agreement shall remain in full force and
effect, regardless of (i) any investigation made by or on behalf of the Company,
any of its officers or directors, any Underwriter or any controlling person
referred to in Section 7 hereof and (ii) delivery of and payment for the Shares.
The respective agreements, covenants, indemnities and other statements set forth
in Sections 6 and 8 hereof shall remain in full force and effect, regardless of
any termination or cancellation of this Agreement.

successors and legal representatives, and nothing expressed or mentioned in this
Agreement is intended or shall be construed to give any other person any legal

shall not be assignable by either party hereto without the prior written consent
of the other party.

              (Pursuant to Article 5.01 of the General Corporation
                    Law of the Commonwealth of Puerto Rico)

         We, the undersigned, Angel Alvarez-Perez and Antonio R. Escriba,
Chairman of the Board, Chief Executive Officer & President and Secretary,
respectively of FIRST BANCORP. (hereinafter called the "Corporation"), a
corporation duly organized and existing under the laws of the Commonwealth of
Puerto Rico, do hereby certify that, pursuant to the authority conferred upon
the Board of Directors of the Corporation by the Certificate of Incorporation of
the Corporation and resolutions adopted by the Board of Directors creating a
committee thereof known as the "Preferred Stock Designation and Pricing
Committee", the said Preferred Stock Designation and Pricing Committee on ,
__________, 1999, adopted the following resolutions creating a series of _____
shares of Preferred Stock designated as the "___% Noncumulative Perpetual
Monthly Income Preferred Stock, Series A."

                  RESOLVED, that pursuant to the authority expressly granted to
         and vested in the Board of Directors of the Corporation in accordance
         with the provisions of its Certificate of Incorporation, a series of
         Preferred Stock of the Corporation be and it hereby is created.

                  FURTHER RESOLVED, that the Preferred Stock Designation and
         Pricing Committee designated by the Board of Directors has determined
         that the preferences and relative, participating, optional or other
         special rights of the shares of such series of Preferred Stock, and
         the qualifications, limitations or restrictions thereof, as stated and
         expressed herein, are under the circumstances prevailing on the date
         hereof fair and equitable to all the existing shareholders of the
         Corporation.

                  FURTHER RESOLVED, that the designation and amount of such

         optional or other special rights of the shares of such series of

         thereof are as follows:

         A.       DESIGNATION AND AMOUNT

                  The shares of such series of Preferred Stock shall be
         designated as the "__% Noncumulative Perpetual Monthly Income Preferred
         Stock, Series A" (hereinafter called the "Series A Preferred Stock"),
         and the number of authorized shares constituting such series shall be
         ________.

         B.       DIVIDENDS

                  1. Holders of record of the Series A Preferred Stock
         ("Holders") will be entitled to receive, when, as and if declared by
         the Board of Directors of the Corporation, out of funds of the
         Corporation legally available therefor, noncumulative cash dividends
         at the annual rate per share of __% of their liquidation preferences,
         or $____ per share per month, with each aggregate payment made to each
         record holder of the Series A Preferred Stock being rounded to the
         next lowest cent.


<PAGE>   2



                  2. Dividends on the Series A Preferred Stock will accrue from
         their date of original issuance and will be payable (when, as and if
         declared by the Board of Directors of the Corporation out of funds of
         the Corporation legally available therefor) monthly in arrears in
         United States dollars commencing on _____________, 1999, and on the
         last day of each calendar month of each year thereafter to the holders
         of record of the Series A Preferred Stock as they appear on the books
         of the Corporation on the second Business Day (as defined below)
         immediately preceding the relevant date of payment. In the case of the
         dividend payable on __________, 1999, such dividend shall cover the
         period from the date of issuance of the Series A Preferred Stock to
         __________, 1999. In the event that any date on which dividends are
         payable is not a Business Day, then payment of the dividend payable on
         such date will be made on the next succeeding Business Day without any
         interest or other payment in respect of any such delay, except that,
         if such Business Day is in the next succeeding calendar year, such
         payment will be made on the Business Day immediately preceding the
         relevant date of payment, in each case with the same force and effect
         as if made on such date. A "Business Day" is a day other than a
         Saturday, Sunday or a general bank holiday in San Juan, Puerto Rico or
         New York, New York.

                  3. Dividends on the Series A Preferred Stock will be
         noncumulative. The Corporation is not obligated or required to declare
         or pay dividends on the Series A Preferred Stock, even if it has funds
         available for the payment of such dividends. If the Board of Directors
         of the Corporation or an authorized committee thereof does not declare
         a dividend payable on a dividend payment date in respect of the Series
         A Preferred Stock, then the holders of such Series A Preferred Stock
         shall have no right to receive a dividend in respect of the monthly
         dividend period ending on such dividend payment date and the Company
         will have no obligation to pay the dividend accrued for such monthly
         dividend period or to pay any interest thereon, whether or not
         dividends on such Series A Preferred Stock are declared for any future
         monthly dividend period.

                  4. The amount of dividends payable for any monthly dividend
         period will be computed on the basis of twelve 30-day months and a
         360-day year. The amount of dividends payable for any period shorter
         than a full monthly dividend period will be computed on the basis of
         the actual number of days elapsed in such period.

                  5. Subject to any applicable fiscal or other laws and
         regulations, each dividend payment will be made by dollar check drawn
         on a bank in New York, New York or San Juan, Puerto Rico and mailed to
         the record holder thereof at such holder's address as it appears on
         the register for such Series A Preferred Stock.

                  6. So long as any shares of the Series A Preferred Stock
         remain outstanding, the Corporation shall not declare, set apart or
         pay any dividend or make any other distribution of assets (other than
         dividends paid or other distributions made in stock of the Corporation
         ranking junior to the Series A Preferred Stock as to the payment of
         dividends and the distribution of assets upon liquidation, dissolution
         or winding up of the Corporation) on, or redeem, purchase, set apart
         or otherwise acquire (except upon conversion or exchange for stock of
         the Corporation ranking junior to the Series A Preferred Stock as to
         the payment of dividends and the distribution of assets upon
         liquidation, dissolution or winding up of the Corporation), shares of
         common stock or of any other class of stock of the Corporation ranking
         junior to the Series A Preferred Stock as to the payment of dividends
         or the distribution of assets upon liquidation, dissolution or winding
         up of the Corporation, unless (i) all accrued and unpaid dividends on
         the Series A Preferred Stock for the twelve monthly dividend



                                       2

<PAGE>   3



         periods ending on the immediately preceding dividend payment date
         shall have been paid or are paid contemporaneously and the full
         monthly dividend on the Series A Preferred Stock for the then current
         month has been or is contemporaneously declared and paid or declared
         and set apart for payment, and (ii) the Corporation has not defaulted
         in the payment of the redemption price of any shares of Series A
         Preferred Stock called for redemption.

                  7. When dividends are not paid in full on the Series A
         Preferred Stock and any other shares of stock of the Corporation
         ranking on a parity as to the payment of dividends with the Series A
         Preferred Stock, all dividends declared upon the Series A Preferred
         Stock and any such other shares of stock of the Corporation will be
         declared pro rata so that the amount of dividends declared per share
         on the Series A Preferred Stock and any such other shares of stock
         will in all cases bear to each other the same ratio that the
         liquidation preference per share of the Series A Preferred Stock and
         any such other shares of stock bear to each other.

                  8. Holders of record of the Series A Preferred Stock will not
         be entitled to any dividend, whether payable in cash, property or
         stock, in excess of the dividends provided for herein on the shares of
         Series A Preferred Stock.

         C.       CONVERSION

                  1. The Series A Preferred stock will not be convertible into
         or exchangeable for any other securities of the Corporation.

         D.       REDEMPTION AT THE OPTION OF THE CORPORATION

                  1. The shares of the Series A Preferred Stock are not
         redeemable prior to ______, 2004. On and after that date, the shares
         of the Series A Preferred Stock will be redeemable in whole or in part
         from time to time at the option of the Corporation, with the consent
         of the Board of Governors of the Federal Reserve System (the "Federal
         Reserve Board") to the extent required by D.8 below, upon not less

                  2. In the event that less than all of the outstanding shares
         of the Series A Preferred Stock are to be redeemed in any redemption
         at the option of the Corporation, the total number of shares to be
         redeemed in such redemption shall be determined by the Board of
         Directors and the shares to be redeemed shall be allocated pro rata or
         by lot as may be determined by the Board of Directors or by such other
         method as the Board of Directors may approve and deem equitable,
         including any method to conform to any rule or regulation of any
         national or regional stock exchange or automated quotation system upon
         which the shares of the Series A Preferred Stock may at the time be
         listed or



                                       3

<PAGE>   4



         eligible for quotation.

                  3. Notice of any proposed redemption shall be given by the
         Corporation by mailing a copy of such notice to the holders of record
         of the shares of Series A Preferred Stock to be redeemed, at their
         address of record, not more than sixty nor less than thirty days prior
         to the redemption date. The notice of redemption to each holder of
         shares of Series A Preferred Stock shall specify the number of shares
         of Series A Preferred Stock to be redeemed, the redemption date and
         the redemption price payable to such holder upon redemption, and shall
         state that from and after said date dividends thereon will cease to
         accrue. If less than all the shares owned by a holder are then to be
         redeemed at the option of the Corporation, the notice shall also
         specify the number of shares of Series A Preferred Stock which are to
         be redeemed and the numbers of the certificates representing such
         shares. Any notice which is mailed as herein provided shall be
         conclusively presumed to have been duly given, whether or not the
         stockholder receives such notice; and failure duly to give such notice
         by mail, or any defect in such notice, to the holders of any stock
         designated for redemption shall not affect the validity of the
         proceedings for the redemption of any other shares of Series A
         Preferred Stock.

                  4. Notice having been mailed as aforesaid, from and after the
         redemption date (unless default be made in the payment of the
         redemption price for any shares to be redeemed), all dividends on the
         shares of Series A Preferred Stock called for redemption shall cease
         to accrue and all rights of the holders of such shares as stockholders
         of the Corporation by reason of the ownership of such shares (except
         the right to receive the redemption price, on presentation and
         surrender of the respective certificates representing the redeemed
         shares), shall cease on the redemption date, and such shares shall not
         after the redemption date be deemed to be outstanding. In case less
         than all the shares represented by such certificate are redeemed, a
         new certificate shall be issued without cost to the holder thereof
         representing the unredeemed shares.

                  5. At its option, the Corporation may, on or prior to the
         redemption date, irrevocably deposit the aggregate amount payable upon
         redemption of the shares of the Series A Preferred Stock to be
         redeemed with a bank or trust company designated by the Board of
         Directors having its principal office in New York, New York, San Juan,
         Puerto Rico, or any other city in which the Corporation shall at that
         time maintain a transfer agency with respect to its capital stock, and
         having a combined capital and surplus (as shown by its latest
         published statement) of at least $50,000,000 (hereinafter referred to
         as the "Depositary"), to be held in trust by the Depositary for
         payment to the holders of the shares of the Series A Preferred Stock
         then to be redeemed. If such deposit is made and the funds so
         deposited are made immediately available to the holders of the shares
         of the Series A Preferred Stock to be redeemed, the Corporation shall
         thereupon be released and discharged (subject to the provisions of
         Section D.6) from any obligation to make payment of the amount payable
         upon redemption of the shares of the Series A Preferred Stock to be
         redeemed, and the holders of such shares shall look only to the
         Depositary for such payment.

                  6. Any funds remaining unclaimed at the end of two years from
         and after the redemption date in respect of which such funds were
         deposited shall be returned to the Corporation forthwith and
         thereafter the holders of shares of the Series A Preferred Stock
         called for redemption with respect to which such funds were deposited
         shall look only to the Corporation for the payment of the redemption
         price thereof. Any interest accrued on any funds deposited with the
         Depositary shall belong to the Corporation and shall be paid to it
         from time to time on demand.

<PAGE>   5



                  7. Any shares of the Series A Preferred Stock which shall at
         any time have been redeemed shall, after such redemption, have the
         status of authorized but unissued shares of Preferred Stock, without
         designation as to series, until such shares are once more designated
         as part of a particular series by the Board of Directors.

                  8. To the extent required to have the Series A Preferred
         Stock treated as Tier 1 capital for bank regulatory purposes or
         otherwise required by applicable regulations of the Federal Reserve
         Board, the shares of Series A Preferred Stock may not be redeemed by
         the Company without the prior consent of the Federal Reserve Board.

         E.       LIQUIDATION PREFERENCE

                  1. Upon any voluntary or involuntary liquidation,
         dissolution, or winding up of the Corporation, the then record holders
         of shares of Series A Preferred Stock will be entitled to receive out
         of the assets of the Corporation available for distribution to
         shareholders, before any distribution is made to holders of common
         stock or any other equity securities of the Corporation ranking junior
         upon liquidation to the Series A Preferred Stock, distributions upon
         liquidation in the amount of $25.00 per share plus an amount equal to
         any accrued and unpaid dividends for the current monthly dividend
         period to the date of payment. Such amount shall be paid to the
         holders of the Series A Preferred Stock prior to any payment or
         distribution to the holders of the common stock of the Corporation or
         any other class of stock or series thereof of the Corporation ranking
         junior to the Series A Preferred Stock in respect of dividends or as
         to the distribution of assets upon liquidation.

                  2. If upon any voluntary or involuntary liquidation,
         dissolution or winding up of the Corporation, the amounts payable with
         respect to the Series A Preferred Stock and any other shares of stock
         of the Corporation ranking as to any such distribution on a parity
         with the Series A Preferred Stock are not paid in full, the holders of
         the Series A Preferred Stock and of such other shares will share
         ratably in any such distribution of assets of the Corporation in
         proportion to the full liquidation preferences to which each is
         entitled. After payment of the full amount of the liquidation
         preference to which they would otherwise be entitled, the holders of
         shares of Series A Preferred Stock will not be entitled to any further
         participation in any distribution of assets of the Corporation.

                  3. Neither the consolidation or merger of the Corporation
         with any other corporation, nor any sale, lease or conveyance of all
         or any part of the property or business of the Corporation, shall be
         deemed to be a liquidation, dissolution, or winding up of the
         Corporation.

         F.       VOTING RIGHTS

                  1. Except as described in this Section F, or except as
         required by applicable law, holders of the Series A Preferred Stock
         will not be entitled to receive notice of or attend or vote at any
         meeting of stockholders of the Corporation.

                  2. If the Corporation does not pay dividends in full on the
         Series A Preferred Stock for eighteen monthly dividend periods
         (whether consecutive or not), the holders of outstanding shares of the
         Series A Preferred Stock, together with the holders of any other
         shares of stock of the Corporation having the right to vote for the
         election of directors solely in the event of any failure to pay
         dividends, acting as a single class without regard to series, will be
         entitled, by written notice to



                                       5

<PAGE>   6



         the Corporation given by the holders of a majority in liquidation
         preference of such shares or by ordinary resolution passed by the
         holders of a majority in liquidation preference of such shares present
         in person or by proxy at a separate general meeting of such holders
         convened for the purpose, to appoint two additional members of the
         Board of Directors of the Corporation, to remove any such member from
         office and to appoint another person in place of such member. Not
         later than 30 days after such entitlement arises, if written notice by
         a majority of the holders of such shares has not been given as
         provided for in the preceding sentence, the Board of Directors or an
         authorized committee thereof will convene a separate general meeting
         for the above purpose. If the Board of Directors or such authorized
         committee fails to convene such meeting within such 30-day period, the
         holders of 10% of the outstanding shares of the Series A Preferred
         Stock and any such other stock will be entitled to convene such
         meeting. The provisions of the Certificate of Incorporation and
         By-laws of the Corporation relating to the convening and conduct of
         general meetings of stockholders will apply with respect to any such
         separate general meeting. Any member of the Board of Directors so
         appointed shall vacate office if, following the event which gave rise
         to such appointment, the Corporation shall have resumed the payment of
         dividends in full on the Series A Preferred Stock and each such other
         series of stock for twelve consecutive monthly dividend periods.

                  3. Any variation or abrogation of the rights, preferences and
         privileges of the Series A Preferred Stock by way of amendment of the
         Corporation's Certificate of Incorporation or otherwise (including,
         without limitation, the authorization or issuance of any shares of the
         Corporation ranking, as to dividend rights or rights on liquidation,
         winding up and dissolution, senior to the Series A Preferred Stock)
         shall not be effective (unless otherwise required by applicable law)
         except with the consent in writing of the holders of at least two
         thirds of the outstanding aggregate liquidation preference of the
         outstanding shares of the Series A Preferred Stock or with the
         sanction of a special resolution passed at a separate general meeting
         by the holders of at least two thirds of the aggregate liquidation
         preference of the outstanding shares of the Series A Preferred Stock.
         Notwithstanding the foregoing, the Corporation may, without the
         consent or sanction of the holders of the Series A Preferred Stock,
         authorize and issue shares of the Corporation ranking, as to dividend
         rights and rights on liquidation, winding up and dissolution, on a
         parity with or junior to the Series A Preferred Stock.

                  4. No vote of the holders of the Series A Preferred Stock
         will be required for the Corporation to redeem or purchase and cancel
         the Series A Preferred Stock in accordance with the Certificate of
         Incorporation of the Corporation.

                  5. The Corporation will cause a notice of any meeting at
         which holders of any series of Preferred Stock are entitled to vote to
         be mailed to each record holder of such series of Preferred Stock.
         Each such notice will include a statement setting forth (i) the date
         of such meeting, (ii) a description of any resolution to be proposed
         for adoption at such meeting on which such holders are entitled to
         vote and (iii) instructions for deliveries of proxies.

                  6. Except as set forth in this Section F, holders of Series A
         Preferred Stock shall have no special voting rights and their consent
         shall not be required (except to the extent they are entitled to vote
         as set forth herein) for taking any corporate action.

<PAGE>   7



                  The Series A Preferred Stock will, with respect to dividend
         rights and rights on liquidation, winding up and dissolution, rank (i)
         senior to all classes of common stock of the Corporation and to all
         other equity securities issued by the Corporation the terms of which
         specifically provide that such equity securities will rank junior to
         the Series A Preferred Stock (or to a number of series of Preferred
         Stock which includes the Series A Preferred Stock); (ii) on a parity
         with all other equity securities issued by the Corporation the terms
         of which specifically provide that such equity securities will rank on
         a parity with the Series A Preferred Stock (or with a number of series
         of Preferred Stock which includes the Series A Preferred Stock); and
         (iii) junior to all equity securities issued by the Corporation the
         terms of which specifically provide that such equity securities will
         rank senior to the Series A Preferred Stock (or to a number of series
         of Preferred Stock which includes the Series A Preferred Stock). For
         this purpose, the term "equity securities" does not include debt
         securities convertible into or exchangeable for equity securities.

         H.       FORM OF CERTIFICATE FOR SERIES A PREFERRED STOCK; TRANSFER AND
                  REGISTRATION

                  1. The Series A Preferred Stock shall be issued in registered
         form only. The Corporation may treat the record holder of a share of
         Series A Preferred Stock, including the Depository Trust Company and
         its nominee and any other holder that holds such share on behalf of
         any other person, as such record holder appears on the books of the
         registrar for the Series A Preferred Stock, as the sole owner of such
         share for all purposes.

                  2. The transfer of a share of Series A Preferred Stock may be
         registered upon the surrender of the certificate evidencing the share
         of Series A Preferred Stock to be transferred, together with the form
         of transfer endorsed on it duly completed and executed, at the office
         of the transfer agent and registrar.

                  3. Registration of transfers of shares of Series A Preferred
         Stock will be effected without charge by or on behalf of the
         Corporation, but upon payment (or the giving of such indemnity as the
         transfer agent and registrar may require) in respect of any tax or
         other governmental charges which may be imposed in relation to it.

                  4. The corporation will not be required to register the
         transfer of a share of Series A Preferred Stock after such share has
         been called for redemption.

         I.       REPLACEMENT OF LOST CERTIFICATES

                  If any certificate for a share of Series A Preferred Stock is
         mutilated or alleged to have been lost, stolen or destroyed, a new
         certificate representing the same share shall be issued to the holder
         upon request subject to delivery of the old certificate or, if alleged
         to have been lost, stolen or destroyed, compliance with such
         conditions as to evidence, indemnity and the payment of out-of-pocket
         expenses of the Corporation in connection with the request as the
         Board of Directors of the Corporation may determine.

         J.       NO PREEMPTIVE RIGHTS

                  Holders of the Series A Preferred Stock will have no
         preemptive or preferential rights to



                                       7

         purchase any securities of the Corporation.

         K.       NO REPURCHASE AT THE OPTION OF HOLDERS; MISCELLANEOUS

                  Holders of Series A Preferred Stock will have no right to
         require the Corporation to redeem or repurchase any shares of Series A
         Preferred Stock, and the shares of Series A Preferred Stock are not
         subject to any sinking fund or similar obligation. The Corporation
         may, at its option, purchase shares of the Series A Preferred Stock
         from holders thereof from time to time, by tender, in privately
         negotiated transactions or otherwise.

         The undersigned hereby certify that the capital of the Corporation
will not be reduced under or by reason of the adoption of the above resolutions
providing for the creation of the above described series of Preferred Stock.

         IN WITNESS WHEREOF, the Corporation has caused its corporate seal to
be hereunto affixed and this Certificate to be signed by Angel Alvarez-Perez,

Dear Sirs:

         In connection with the registration under the Securities Act of 1933,
as amended (the "Act"), of up to 4,140,000 shares (the "Shares") of
Noncumulative Perpetual Monthly Income Preferred Stock, Series A, $1.00 par
value per share, of First BanCorp. (the "Company") to be registered under the
Act pursuant to the Company's Registration Statement on Form S-3, to be filed
with the Securities and Exchange Commission on or about March 29, 1999 (the
"Registration Statement"), we, as your counsel, have examined such documents,
corporate records and other instruments, and such questions of law, as we have
deemed necessary or appropriate for the purposes of this opinion.

         Upon the basis of such examination, we are of the opinion that when the
Registration Statement shall have been declared effective, the certificate of
resolutions containing the designation of the relative rights and preferences of
the Shares has been duly filed with the Department of State of the Commonwealth
of Puerto Rico, the Shares have been issued in accordance with the authorization
of the Board of Directors of the Company, and when the Shares have been duly
countersigned by the Company's transfer agent and registrar and sold and
delivered as contemplated by the Registration Statement and the Underwriting
Agreement referred to therein, the Shares will be duly authorized and validly
issued, fully-paid and nonassessable when delivered against payment therefor.

         We are members of the Bar of the Commonwealth of Puerto Rico. The
opinions expressed above are limited to the laws of the Commonwealth of Puerto
Rico and any applicable Federal laws and we do not purport to be experts in, or
to render any opinions with respect to, the laws of any state or other
jurisdiction other than the laws of the Commonwealth of Puerto Rico and the
Federal laws

First BanCorp.

Dear Sirs:

         We have acted as counsel to First BanCorp. (the "Company") in
connection with the registration under the Securities Act of 1933, as amended
(the "Act"), of up to 4,140,000 shares (the "Shares") of Noncumulative Perpetual
Monthly Income Preferred Stock, Series A, $1.00 par value per share, to be
registered under the Act pursuant to the Company's Registration Statement on
Form S-3, to be filed with the Securities and Exchange Commission on or about
March 29, 1999 (the "Registration Statement").

         We have examined the prospectus contained in the Registration Statement
(the "Prospectus") and we have reviewed the discussion of certain Federal and
Puerto Rico income tax considerations of the proposed offering described in the
Prospectus (the "Tax Discussion") appearing under the captions "Taxation,"
"Puerto Rico Taxation" and "United States Taxation." We have also reviewed such
