            CONSOLIDATED RATIO OF EARNINGS TO COMBINED FIXED CHARGES
                          AND PREFERRED STOCK DIVIDENDS

         The ratios shown below measure Oriental Financial Group's ability to
generate sufficient earnings to pay the fixed charges or expenses of its debt
and preferred stock dividends. The ratios of earnings to combined fixed charges
and preferred stock dividends were computed by dividing earnings by combined
fixed charges and preferred stock dividends.

         For purposes of computing the consolidated ratios of earnings to
combined fixed charges and preferred stock dividends, earnings consist of pretax
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
Oriental Financial Group's estimate of the interest component of rental expense.
Ratios are presented both including and excluding interest on deposits.

         During the periods shown above Oriental Financial Group did not have
preferred stock issued and outstanding.

                                  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 Oriental Financial
Group'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 ORIENTAL FINANCIAL GROUP'S ABILITY TO PAY 
DIVIDENDS

         Oriental Financial Group may not be able to pay dividends in the future
if it does not earn sufficient net income. Federal Reserve Board policy is that
a bank holding company should pay dividends only out of its current net income.
Oriental Financial Group had net income of $21.4 million for the year ended June
30, 1998 and of $12.4 million for the six-month period ended December 31, 1998.
Banking regulations may also restrict the ability of Oriental Bank and Trust to
make distributions to Oriental Financial Group. These distributions may be
necessary for Oriental Financial Group to pay dividends on the Series A
Preferred Stock.

FLUCTUATIONS IN INTEREST RATES MAY HURT ORIENTAL FINANCIAL GROUP'S BUSINESS

         Interest rate fluctuations is the primary market risk affecting
Oriental Financial Group. Changes in interest rates affect the following areas,
among others, of Oriental Financial Group's business:

         -        the number of mortgage loans originated;
         -        the interest income earned on loans and securities;
         -        the value of securities holdings; and
         -        gain from sales of loans and securities.

ORIENTAL FINANCIAL GROUP IS AT RISK BECAUSE ITS BUSINESS IS CONDUCTED IN 
PUERTO RICO

         Because all of Oriental Financial Group's business activities are
conducted in Puerto Rico and a substantial portion of its credit exposure is in
Puerto Rico, Oriental Financial Group is at risk from adverse economic,
political or business developments and natural hazards that affect Puerto Rico.
If Puerto Rico's economy experiences an overall decline as a result of these
adverse developments or natural hazards, the rates of delinquencies,
foreclosures, bankruptcies and losses on loan portfolios would probably increase
substantially. This would cause Oriental Financial Group's profitability to
decrease.

ORIENTAL FINANCIAL GROUP'S BUSINESS WOULD BE DISRUPTED IF ITS COMPUTER SYSTEMS 
CANNOT WORK PROPERLY WITH YEAR 2000 DATA

         Oriental Financial Group 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. Oriental Financial Group has taken steps that it believes are adequate to
make sure this does not happen through a comprehensive year 2000 compliance
program. However, Oriental Financial Group 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 Oriental Financial Group's daily operations. Oriental Financial Group
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 Oriental
Financial Group's operations, performance and financial condition, including its
future economic performance, plans and objectives and the likelihood of success
in developing and expanding its business. These statements are based upon a
number of assumptions and estimates which are subject to significant
uncertainties, many of which are beyond the control of Oriental Financial Group.
The words "may," "would," "could," "will," "expect," "anticipate," "believe,"

                                 USE OF PROCEEDS

         The net proceeds to Oriental Financial Group after deducting expenses
from the sale of shares of Series A Preferred Stock are estimated at
approximately $29,395,312. If the Underwriters' over-allotment option is
exercised in full, the net proceeds are estimated at $33,753,562. Oriental
Financial Group intends to use the net proceeds for general corporate purposes,
which may include:

         -        making capital contributions to its banking and non-banking
                  subsidiaries;

         -        increasing working capital; and

         -        repurchasing common stock under a repurchase program.

                             SELECTED FINANCIAL DATA

         The following table shows certain selected consolidated financial and
operating data of Oriental Financial Group on a historical basis as of and for
the six-month periods ended December 31, 1998 and 1997, and for each of the five
fiscal years in the period ended June 30, 1998. This information should be read
together with Oriental Financial Group's Consolidated Financial Statements and
the related notes incorporated by reference in this prospectus. Financial
information for the six-month periods ended December 31, 1998 and 1997, is
derived from unaudited financial statements, which, in the opinion of
management, include all adjustments necessary for a fair presentation of the
results for those periods. These adjustments consist only of normal recurring
accruals. Results for the six-month period ended December 31, 1998, are not
necessarily indicative of results for the full year.

         In fiscal 1998 Oriental Financial Group earned $21.4 million or 20%
over the $17.9 million earned in fiscal 1997, excluding a one-time Savings
Association Insurance Fund assessment. The increase in net income was mainly due
to increases in net interest income and non-interest income. Earnings per common
share on a diluted basis were $1.56 in fiscal 1998 or 19% higher than the $1.31
in fiscal 1997, in each case as adjusted to reflect a four-for-three stock split
effected on October 15, 1998 and a five-for-four stock split effected on October
15, 1997. Oriental Financial Group's profitability ratios for fiscal 1998
resulted in a return on average assets of 1.74%, compared to 1.84% in fiscal
1997, and a return on average stockholders' equity of 21.24%, compared to 21.17%
in fiscal 1997.

         Net interest income for fiscal 1998 reached $43.4 million, 16% or $5.9
million higher than the $37.5 million earned in fiscal 1997. This improvement in
net interest income reflects an increase of $6.3 million due to a higher volume
of net interest-earning assets; partially offset by an unfavorable effect in
interest rates of $376,000, as a result of a reduction of 39 basis points in the
interest rate margin. In fiscal 1998 the interest rate spread was 3.57%,
compared to 3.89% in fiscal 1997, and the net interest margin was 3.80%,
compared to 4.19% in fiscal 1997.

         Non-interest income rose 30% to $22.6 million in fiscal 1998, from
$17.4 million in fiscal 1997. Trust, money management and brokerage fees, the
principal components of recurring non-interest income, totaled $8.4 million,
which represents an increase of 24% from the $6.8 million earned in fiscal 1997.
Noninterest income from recurring mortgage banking activities, excluding fees
from its mortgage loan servicing portfolio, reached $4.5 million in fiscal 1998,
an increase of 95% over the $2.3 million earned in fiscal 1997. This increase
was the result of greater mortgage origination volume and favorable market
conditions for the sale of such loans in the secondary market.

         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
efficiency ratio is computed by dividing recurring operating expenses by the sum
of net interest income and recurring non-interest income. The expense ratio is
computed by dividing net recurring operating expenses, which represents
recurring non-interest expenses less recurring non-interest income, by total
average interest-earning assets for the period. The average equity to average
total assets ratio is computed by dividing average assets for the period by
average stockholders' equity. The interest rate spread is the percentage
difference or margin between the yield on interest-earning assets and the
effective interest rate paid on interest-bearing liabilities. All ratios have
been computed using month-end averages. All ratios, except for the interest rate
spread, for the six-month periods ended December 31, 1998 and 1997, have been
presented on an annualized basis. All per share information shown in the table
has been adjusted to reflect a four-for-three stock split effected on October
15, 1998 and a five-for-four stock split effected on October 15, 1997.

            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 Oriental Financial Group's certificate of
incorporation, as amended, 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 Oriental Financial Group'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 per share. Oriental
Financial Group 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 their 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
Oriental Financial Group on the fifteenth day of the month in which the
dividends are payable. 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 $ per share. 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 Oriental
Financial Group 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 Oriental Financial
Group ranking junior to he Series A Preferred Stock as to the payment of
dividends or as to the distribution of assets upon liquidation, dissolution or
winding up of Oriental Financial Group, 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



                                       13
<PAGE>   15

has been or is contemporaneously declared and paid or declared and set apart for
payment, and (3) Oriental Financial Group 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 Oriental Financial Group." The
above limitations do not apply to stock dividends or other distributions made in
stock of Oriental Financial Group 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 Oriental
Financial Group ranking junior to the Series A Preferred Stock as to the payment
of dividends and as to the distribution of assets.

         If Oriental Financial Group 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 full dividends on the Series A Preferred Stock, for the
then-current dividend period (which shall not include any accumulation in
respect of unpaid dividends for prior dividend periods) and full dividends,
including required or permitted accumulations, if any, on such other classes of
equally ranked stock, bear to each other.

         For a discussion of the tax treatment of distributions to stockholders
see "Taxation," "Puerto Rico Taxation," and "United States Taxation," and for a
discussion on certain potential regulatory limitations on Oriental Financial
Group's ability to pay dividends, see "Risk Factors -- Banking Regulations May
Restrict Oriental Financial Group's Ability to Pay Dividends."

NO CONVERSION OR EXCHANGE RIGHTS

         The Series A Preferred Stock will not be convertible into or
exchangeable for any other securities of Oriental Financial Group.

Preferred Stock prior to    , 2004. On and after that date, Oriental Financial
Group 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

         In the event that Oriental Financial Group 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 Oriental Financial Group 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.

         Oriental Financial Group 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 Oriental Financial Group
redeems less than all the shares owned by a holder, the notice will 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 will be conclusively presumed
to have been properly given, whether or not the stockholder receives this
notice. The failure by Oriental Financial Group to give this notice by mail, or
any defect in the notice, to the holders of any shares designated for redemption
will 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 Oriental Financial
Group pays the redemption price, from and after the redemption date, all
dividends on the shares of Series A Preferred Stock called for redemption will
cease to accrue and all rights of the holders of the shares being redeemed as
stockholders of Oriental Financial Group shall cease on the redemption date.
Holders will retain the right to receive the redemption price upon presentation
of their stock certificates. If Oriental Financial Group 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.

         At its option, Oriental Financial Group 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 Oriental Financial Group having its principal office
in New York, New York, San Juan, Puerto Rico, or any other city in which
Oriental Financial Group 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 (hereinafter referred to as the "Depositary"). 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, Oriental Financial Group 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
Oriental Financial Group. After the funds are returned to Oriental Financial
Group, the holders of shares called for redemption shall look only to Oriental
Financial Group for the payment of the redemption price. Any interest accrued on
any funds deposited with the Depositary will belong to Oriental Financial Group
and shall be paid to Oriental Financial Group 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 serial
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
Oriental Financial Group.

         Certain Regulatory Considerations Affecting Redemptions

         Under regulations adopted by the Federal Reserve Board, Oriental
Financial Group 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 Oriental Financial Group's condition and
circumstances warrant the reduction of a source of permanent capital.

         Also, under Section 8.04 of the Puerto Rico General Corporation Law,
Oriental Financial Group 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 Oriental Financial
Group, the record holders of shares of Series A Preferred Stock will be entitled
to receive out of the assets of Oriental Financial Group available for
distribution to shareholders, before any distribution is made to holders of
common stock or any other equity securities of Oriental Financial Group ranking
junior upon liquidation to the Series A Preferred Stock, the amount of $25 per
share plus an amount equal to any accrued and unpaid dividends for the current
monthly dividend period to the date of payment.

         If Oriental Financial Group 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 Oriental Financial Group.

         A consolidation or merger of Oriental Financial Group with any other
corporation, or any sale, lease or conveyance of all or any part of the property
or business of Oriental Financial Group, shall not be deemed to be a
liquidation, dissolution, or winding up of Oriental Financial Group.

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 Oriental Financial
Group, except as described below.

         If Oriental Financial Group 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 having the right
to vote for



                                       16
<PAGE>   18
 
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 to
the board of directors of Oriental Financial Group. 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 of the
appointment to Oriental Financial Group 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 Oriental Financial Group 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, as amended, and
by-laws of Oriental Financial Group 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 Oriental Financial Group 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. The
by-laws of Oriental Financial Group provide that the board of directors shall
consist of such number of directors as established from time to time by a vote
of a majority of the board of directors, provided that no decrease in the number
of directors shall have the effect of shortening the term of any incumbent
director. As of the date of this prospectus, Oriental Financial Group's board of
directors consisted of nine 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 Oriental Financial Group 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 Oriental Financial Group to redeem or purchase and cancel the Series A
Preferred Stock in accordance with the certificate of incorporation, as amended,
or the Certificate of Designation for the Series A Preferred Stock.

         Oriental Financial Group 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 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 of 5% that
otherwise exercises a "controlling influence" over Oriental Financial Group
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 Office of
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 Office of 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 Office of the
Commissioner has made an administrative determination that these provisions of
the Banking Law are applicable to a change in control of Oriental Financial
Group.

         Pursuant to the Banking Law, if the Office of the Commissioner receives
notice of a proposed transaction that may result in a change of control of
Oriental Financial Group, the Office of the Commissioner is required to
investigate and determine whether a change of control has occurred. The Office
of the Commissioner will issue an authorization for the transfer of control of
Oriental Financial Group if the results of its investigations are in its
judgment satisfactory. The decision of the Office 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 Oriental Financial
                  Group, and to all other equity securities issued by Oriental
                  Financial Group 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
                  Oriental Financial Group the terms of which specifically
                  provide that those equity securities will have equal rank as
                  the Series A Preferred Stock; and

         -        junior to all equity securities issued by Oriental Financial
                  Group the terms of which specifically provide that those
                  equity securities will rank senior to the Series A Preferred
                  Stock.



                                       18
<PAGE>   20

         For this purpose, the term "equity securities" does not include debt
securities convertible into or exchangeable for equity securities.

         Oriental Financial Group may not issue shares ranking, as to dividend
rights or rights on liquidation, winding up and dissolution, senior to the
Series A Preferred Stock, except with the consent of the holders of at least
two-thirds of the outstanding aggregate liquidation preference of the Series A
Preferred Stock. See "Voting Rights" above.

         Oriental Financial Group will not be required to register the transfer
of a share of Series A Preferred Stock after the share has been called for
redemption.

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, the holder may request a new
certificate representing the same share. Oriental Financial Group will issue a
new certificate subject to delivery of the old certificate or, if alleged to
have been lost, stolen or destroyed, compliance with the conditions as to
evidence of ownership and indemnity. In all cases, the holder shall pay the
out-of-pocket expenses of Oriental Financial Group as Oriental Financial Group
may determine.

his shares equals, or by distributing such votes on the same principle among any
number of candidates.

         Subject to the rights of holders of the Series A Preferred Stock and
any other outstanding shares of preferred stock, in the event of the

                                    TAXATION

GENERAL

         In the opinion of McConnell Valdes, San Juan, Puerto Rico, counsel to
Oriental Financial Group, the following discussion summarizes the material
Puerto Rico and United States tax considerations relating to the purchase,
ownership and disposition 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, as well as 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, a "Puerto Rico corporation" is a
corporation organized under the laws of Puerto Rico and a "foreign corporation"
is 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 Oriental
Financial Group on the Series A Preferred Stock will be treated as dividends to
the extent that Oriental Financial Group has current or accumulated earnings and
profits. To the extent that a distribution exceeds Oriental Financial Group'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 declared by a Puerto Rico corporation will constitute
income from sources within Puerto Rico unless the corporation derived less than
20% of its gross income from sources within Puerto Rico for the three taxable
years preceding the year of the declaration. Oriental Financial Group 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 1972.

         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 Oriental
Financial Group or dividends paid on the Series A Preferred Stock. 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%.

         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 name. Similarly, Puerto Rico corporations that own any
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
name in order to ensure that no withholding is made on dividends.



                                       22
<PAGE>   24

         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
Oriental Financial Group. These individuals may elect for the 10% Special Tax
and 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 the making of this election, a separate 10% withholding tax will
be required on the amount of the dividend unless the individual timely files
with Oriental Financial Group or its agent 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 Oriental Financial
Group 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 Oriental
Financial Group 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
Oriental Financial Group.

         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 in the taxable
year of the dividend.

         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 all 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 Puerto Rico
and foreign corporations is equally applicable in the case of most Puerto Rico
and foreign partnerships, respectively.

         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



                                       23
<PAGE>   25
 
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 stockholders' 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 gain will
be withheld at the source; provided, that if the gain resulting from the sale or
exchange represents a net capital gain, 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



                                       24
<PAGE>   26

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 gain will be withheld
at the source and be 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 Puerto Rico and foreign corporations
is equally applicable to most Puerto Rico and foreign partnerships,
respectively.

         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 Oriental
Financial Group's current or accumulated earnings and profits if it 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 the United States Internal Revenue Service under the
United States Internal Revenue Code of 1986, in determining whether a
distribution is essentially equivalent to a dividend. The Department of the
Treasury of Puerto Rico, however, is not bound by IRS determinations on this
issue 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 (Not including
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 clearly provide a source of income
rule for a gain of this nature. As a result thereof, these prospective
shareholders should be aware that a gain realized from a redemption of the
Series A Preferred Stock may be subject to Puerto Rico income tax.



                                       25
<PAGE>   27

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

PROPERTY TAXATION

         The Series A Preferred Stock will not be subject to Puerto Rico
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 existing United
States Internal Revenue Code of 1986 (the "Code") 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 Company 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,



                                       26
<PAGE>   28

         -        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 (or, in certain cases, a portion thereof).

OWNERSHIP AND DISPOSITION OF THE SERIES A PREFERRED STOCK

         Taxation of Dividends.

         General. Under the source of income rules of the Code, dividends on the
Series A Preferred Stock will constitute gross income from sources outside the
United States if less than 25% of Oriental Financial Group's gross income on an
ongoing basis is effectively connected with a trade or business in the United
States. Since its incorporation in 1972, Oriental Financial Group has not, nor
does it expect in the future, that 25% or more of its gross income will be
effectively connected with a trade or business in the United States.
Accordingly, dividends on the Series A Preferred Stock distributed by Oriental
Financial Group will constitute gross income from sources outside the United
States so long as Oriental Financial Group continues to meet the gross income
test described above.

         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
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 Oriental Financial Group 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
Oriental Financial Group exceeds its current and accumulated earnings and
profits as determined under United States federal income tax principles, it 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,
any Puerto Rico income tax imposed on dividends distributed by Oriental
Financial Group 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 Oriental
Financial Group 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 Oriental Financial Group on the Series A Preferred Stock to a
Puerto Rico U.S. Holder will constitute gross income from sources within



                                       27
<PAGE>   29

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
Oriental Financial Group 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 and the PR Corporation is not treated as a
domestic corporation for purposes of the Code. 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.

         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(g)(1) 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.

         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 and the PR Corporation is not treated as a domestic corporation for
purposes of the Code. 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 corporate 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"), Oriental Financial Group
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 Oriental
Financial Group'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 Oriental Financial Group remains
a PFIC, with respect to (1) any "excess distribution" by Oriental Financial
Group 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 Oriental Financial Group
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 Oriental Financial Group were a
PFIC, 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 Oriental Financial Group 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 Oriental Financial Group 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, Oriental
Financial Group 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. The underwriters or
the selected dealers may reallow a commission to certain other dealers not to
exceed $ per share. After the offering to the public, the public offering price,
the concession to selected dealers and the reallowance to other dealers may be
changed by the underwriters.

         Oriental Financial Group has granted the underwriters an option
exercisable for 30 days from the date of this prospectus, to purchase up to
180,000 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 offering of the Series A Preferred Stock is being conducted
pursuant to Rule 2720(d) of the Conduct Rules of the National Association of
Securities Dealers, Inc. because Oriental Financial Services Corp., an indirect
wholly-owned subsidiary of Oriental Financial Group and registered
broker-dealer, will participate as a member of the selling group for the initial
public offering of the Series A Preferred Stock. In accordance with Rule
2720(d), Keefe, Bruyette & Woods, Inc. has acted as "qualified independent
underwriter" and the price of the Series A Preferred Stock was no higher than
that recommended by Keefe, Bruyette & Woods, Inc. as qualified independent
underwriter. Keefe, Bruyette & Woods, Inc., in its role as qualified independent
underwriter, has performed due diligence investigations and reviewed and
participated in the preparation of this prospectus.

         The following table shows the per share and total underwriting
discounts and commissions to be paid to the underwriters by Oriental Financial
Group as well as the proceeds received by Oriental Financial Group 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 180,000 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.

         Oriental Financial Group estimates that the total expenses of this
offering, excluding underwriting discounts and commissions, will be $265,000.
This amount includes the reimbursement of certain out-of-pocket expenses to the
underwriters.

         In connection with this offering, Oriental Financial Group has agreed
to indemnify the underwriters against certain liabilities, including liabilities
under the Securities Act of 1933, as amended, or to contribute to payments that
the underwriters may be required to make in respect thereof.

         The New York Stock Exchange has approved for listing the Series A
Preferred Stock under the symbol "OFGPrA."

         The underwriters have from time to time been customers of, engaged in
transactions with, or performed services for, Oriental Financial Group 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.

         Section 1.02(B)(6) of the Puerto Rico General Corporation Law (the
"PR-GCL") provides that a corporation may include in its certificate of
incorporation a provision eliminating or limiting the personal liability of
members of its board of directors or governing body for breach of a director's
fiduciary duties. However, no such provision may eliminate or limit the
liability of a director for breaching his duty of loyalty, failing to act in
good faith, engaging in intentional misconduct or knowingly violating a law,
paying an unlawful dividend or approving an unlawful stock repurchase, or
obtaining an improper personal benefit.

         Article Ninth of Oriental Financial Group's certificate of
incorporation, as amended, provides that the personal liability of the directors
and officers of Oriental Financial Group for monetary damages shall be
eliminated to the fullest extent permitted by the PR-GCL.

         Section 4.08 of the PR-GCL authorizes a Puerto Rico corporation to
indemnify its officers and directors and to purchase and maintain insurance on
behalf of its officers and directors against liabilities arising out and pending
or threatened actions, suits or proceedings to which such officers or directors
are or may be made parties by reason of being officers or directors of the
corporation. 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 shareholders or otherwise.

         Section 1 of Article VII of Oriental Financial Group's by-laws provides
that directors, officers, employees and agents of Oriental Financial Group shall
be indemnified to the fullest extent authorized by the PR-GCL against expenses
and certain other liabilities arising out of legal action brought or threatened
against them for their conduct on behalf Oriental Financial Group, provided that
each such person acted in good faith and in a manner that he reasonably believed
was in or not opposed to Oriental Financial Group's best interests.
Indemnification by Oriental Financial Group is available in a criminal action
only if such person had no reasonable cause to believe that his conduct was
unlawful.

         Section 4 of Article VII of Oriental Financial Group's by-laws provides
that Oriental Financial Group may maintain insurance covering certain
liabilities of officers, directors, employees and agents of



                                      II-1
<PAGE>   37
 
Oriental Financial Group, whether or not Oriental Financial Group would have the
power or would be required to indemnify them against such liabilities.

         The resolutions of the board of directors adopted on March 30, 1999,
approving the issuance and sale of the Series A Preferred Stock provide that, to
the extent permitted by Oriental Financial Group's certificate of incorporation,
as amended, and applicable law, Oriental Financial Group (1) will indemnify and
hold harmless the directors and executive officers and their attorney-in-facts
who signed this Registration Statement against any losses, claims, damages or
liabilities they may become subject under the Securities Act of 1933, the
Securities Exchange Act of 1934, any state securities or insurance laws or
regulations of any other jurisdiction, insofar as such losses, claims, damages
or liabilities arise in connection with this Registration Statement or any other
registration statement filed in connection with the Series A Preferred Stock;
and (2) shall reimburse each such person for any legal or other expenses
reasonably incurred by him in connection with investigating or defending any
such action or claim.

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:

         (1)      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.



                                      II-2
<PAGE>   38

         (2)      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
Oriental Financial Group pursuant to the provision described under Item 15
above, or otherwise, Oriental Financial Group 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 Oriental Financial Group of expenses
incurred or paid by a director, officer, or controlling person of Oriental
Financial Group 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, Oriental Financial Group 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.

Ladies and Gentlemen:

         ORIENTAL FINANCIAL GROUP INC., a Puerto Rico corporation (the
"Company"), confirms its agreement with you, and each of the other Underwriters
named in Schedule A hereto (collectively, the "Underwriters", which term shall
also include any underwriter substituted as hereinafter provided in Section 10
hereof), for whom you are acting as representatives (in such capacity, the
"Representatives"), with respect to the issue and sale by the Company and the
purchase by the Underwriters, acting severally and not jointly, of the
respective numbers of shares of the Company's ____% Noncumulative Monthly
Income Preferred Stock, Series A ($25 liquidation preference per share) set
forth in said Schedule A, and with respect to the grant by the Company to the
Underwriters, acting severally and not jointly, of the option described in
Section 2(b) hereof to purchase all or any part of 180,000 additional shares of
such preferred stock to cover over-allotments, if any. The aforesaid 1,225,000
shares of preferred stock (the "Initial Securities") to be purchased by the
Underwriters and all or any part of the 180,000 shares of preferred stock
subject to the option described in Section 2(b) hereof (the "Option
Securities") are hereinafter called, collectively, the "Securities".

         The Company understands that the Underwriters propose to make a public
offering of the Securities as soon as the Representatives deem advisable after
this Agreement has been executed and delivered.


<PAGE>   5


         The Company has filed with the Securities and Exchange Commission (the
"Commission") a registration statement on Form S-3 (No. 333-_______ ) covering
the registration of the Securities under the Securities Act of 1933, as amended
(the "1933 Act"), including the related preliminary prospectus. Promptly after
execution and delivery of this Agreement, the Company will prepare and file a
prospectus in accordance with the provisions of Rule 430A ("Rule 430A") of the
rules and regulations of the Commission under the 1933 Act (the "1933 Act
Regulations") and paragraph (b) of Rule 424 ("Rule 424(b)") of the 1933 Act
Regulations. The information included in such prospectus that was omitted from
such registration statement at the time it became effective but that is deemed
to be part of such registration statement at the time it became effective
pursuant to paragraph (b) of Rule 430A is referred to as "Rule 430A
Information". Each prospectus used before such registration statement became
effective, and any prospectus that omitted, as applicable, the Rule 430A
Information that was used after such effectiveness and prior to the execution
and delivery of this Agreement, is herein called a "preliminary prospectus."
Such registration statement, including the exhibits thereto, the documents
incorporated therein by reference and schedules thereto at the time it became
effective and including the Rule 430A Information is herein called the
"Registration Statement." Any registration statement filed pursuant to Rule
462(b) of the 1933 Act Regulations is herein referred to as the "Rule 462(b)
Registration Statement," and after such filing the term "Registration
Statement" shall include the Rule 462(b) Registration Statement. The final
prospectus in the form first furnished to the Underwriters for use in
connection with the offering of the Securities is herein called the
"Prospectus." For purposes of this Agreement, all references to the
Registration Statement, any preliminary prospectus, the Prospectus or any
amendment or supplement to any of the foregoing shall be deemed to include the
copy filed with the Commission pursuant to its Electronic Data Gathering,
Analysis and Retrieval system ("EDGAR").

         All references in this Agreement to financial statements and schedules
and other information which is "contained," "included" or "stated" in the
Registration Statement, any preliminary prospectus or the Prospectus (or other
references of like import) shall be deemed to mean and include all such
financial statements and schedules and other information which is incorporated
by reference in the Registration Statement, any preliminary prospectus or the
Prospectus, as the case may be; and all references in this Agreement to
amendments or supplements to the Registration Statement, any preliminary
prospectus or the Prospectus shall be deemed to mean and include the filing of
any document under the Securities Exchange Act of 1934 (the "1934 Act") which
is incorporated by reference in the Registration Statement, such preliminary
prospectus or the Prospectus, as the case may be.

         SECTION 1.        Representations and Warranties.

         (a)      Representations and Warranties by the Company. The Company
represents and warrants to each Underwriter as of the date hereof, as of the
Closing Time referred to in Section 2(c)
hereof, and as of each Date of Delivery (if any) referred to in Section 2(b)
hereof, and agrees with each Underwriter, as follows:

                  (i)      Compliance with Registration Requirements. Each of
         the Registration Statement and any Rule 462(b) Registration Statement
         has become effective under the 1933


                                       2
<PAGE>   6


         Act and no stop order suspending the effectiveness of the Registration
         Statement or any Rule 462(b) Registration Statement has been issued
         under the 1933 Act and no proceedings for that purpose have been
         instituted or are pending or, to the knowledge of the Company, are
         contemplated by the Commission, and any request on the part of the
         Commission for additional information has been complied with.

                  At the respective times the Registration Statement, any Rule
         462(b) Registration Statement and any post-effective amendments
         thereto became effective and at the Closing Time (and, if any Option
         Securities are purchased, at the Date of Delivery), the Registration
         Statement, the Rule 462(b) Registration Statement and any amendments
         and supplements thereto complied and will comply in all material
         respects with the requirements of the 1933 Act and the 1933 Act
         Regulations and did not and will not contain an untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein not misleading.
         Neither the Prospectus nor any amendments or supplements thereto, at
         the time the Prospectus or any such amendment or supplement was issued
         and at the Closing Time (and, if any Option Securities are purchased,
         at the Date of Delivery), included or will include an untrue statement
         of a material fact or omitted or will 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. The
         representations and warranties in this subsection shall not apply to
         statements in or omissions from the Registration Statement or
         Prospectus made in reliance upon and in conformity with information
         furnished to the Company in writing by any Underwriter through the
         Representatives expressly for use in the Registration Statement or
         Prospectus.

                  Each preliminary prospectus and the prospectus filed as part
         of the Registration Statement as originally filed or as part of any
         amendment thereto, or filed pursuant to Rule 424 under the 1933 Act,
         complied when so filed in all material respects with the 1933 Act
         Regulations and each preliminary prospectus and the Prospectus
         delivered to the Underwriters for use in connection with this offering
         was identical to the electronically transmitted copies thereof filed
         with the Commission pursuant to EDGAR, except to the extent permitted
         by Regulation S-T.

                  There are no contracts or other documents required to be
         filed as exhibits to the Registration Statement by the 1933 Act or the
         1933 Act 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 1933 Act and the 1933 Act Regulations or the 1934 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 with the Commission, conform in all material respects with the


                                       3
<PAGE>   7


         requirements of the 1933 Act and the 1933 Act Regulations and the 1934
         Act and the rules and regulations thereunder, as applicable, and will
         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.

                  (ii)     Independent Accountants. The accountants who
         certified the financial statements and supporting schedules included
         in the Registration Statement are independent public accountants as
         required by the 1933 Act and the 1933 Act Regulations.

                  (iii)    Financial Statements. The consolidated financial
         statements of the Company included or incorporated by reference in the
         Registration Statement and the Prospectus (or, if the Prospectus is
         not in existence, in the most recent preliminary prospectus), together
         with the related schedules and notes, present fairly the financial
         position of the Company and its Subsidiaries (as defined in Section
         1(a)(vi) hereof) at the dates indicated and the consolidated statement
         of operations, stockholders' equity and cash flows of the Company and
         its Subsidiaries for the periods specified; said financial statements
         have been prepared in conformity with generally accepted accounting
         principles ("GAAP") applied on a consistent basis throughout the
         periods involved. The supporting schedules, if any, included in the
         Registration Statement present fairly in accordance with GAAP the
         information required to be stated therein. The selected financial data
         and the summary financial information included in the Prospectus
         present fairly the information shown and have been compiled on a basis
         consistent with that of the audited financial statements included or
         incorporated by reference in the Registration Statement.

                  (iv)     No Material Adverse Change in Business. Since the
         respective dates as of which information is given in the Registration
         Statement and the Prospectus, except as otherwise stated therein, (A)
         there has been no material adverse change in the condition, financial
         or otherwise, or in the earnings, business affairs or business
         prospects of the Company and its Subsidiaries considered as one
         enterprise, whether or not arising in the ordinary course of business
         (a "Material Adverse Effect"), (B) there have been no transactions
         entered into by the Company or any of its subsidiaries, other than
         those in the ordinary course of business, which are material with
         respect to the Company and its subsidiaries considered as one
         enterprise, and (C) except for regular quarterly dividends on the
         Company's Common Stock, par value $1.00 per share (the "Common
         Stock"), since December 31, 1998 there has been no dividend or
         distribution of any kind declared, paid or made by the Company on any
         class of its capital stock.

                  (v)      Good Standing of Company. The Company has been duly
         incorporated and is validly existing as a corporation in good standing
         under the laws of the Commonwealth of Puerto Rico with full corporate
         power and authority to own, lease and operate its properties and
         conduct its business as described in the Prospectus and to enter into
         and perform its obligations under this Agreement; and the Company is
         duly qualified to transact business as a foreign corporation and is in
         good standing under the laws of each jurisdiction in which the


                                       4
<PAGE>   8


         conduct of its business or ownership or leasing of its properties
         requires such qualification and where the failure to be so qualified
         would, individually or in the aggregate, have a Material Adverse
         Effect. The Company is registered as a bank holding company under the
         Bank Holding Company Act of 1956 (the "BHCA") in good standing with
         the Board of Governors of the Federal Reserve System (the "Federal
         Reserve").

                  (vi)     Subsidiaries. The only 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 required 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 Time or the Date of Delivery (if any Option Securities are
         purchased), will own an interest in any corporation, partnership,
         trust, joint venture or other business entity. Each Subsidiary has
         been duly incorporated and is validly existing as a corporation in
         good standing under the laws of the jurisdiction in which it is
         chartered or organized, with full corporate power and authority to
         own, lease and operate its properties and conduct its business as
         described in the Prospectus, and is duly qualified to transact
         business as a foreign corporation and is in good standing under the
         laws of each jurisdiction in which the conduct of its business or
         ownership or leasing of its properties requires such qualification and
         where the failure to be so qualified would, individually or in the
         aggregate, have a Material Adverse Effect. Except as otherwise
         disclosed in the Registration Statement, all of the issued and
         outstanding capital stock of each Subsidiary has been duly authorized
         and validly issued, is fully paid and non-assessable and is owned by
         the Company, directly or through subsidiaries, free and clear of any
         security interest, mortgage, pledge, lien, encumbrance, claim or
         equity; none of the outstanding shares of capital stock of any
         Subsidiary was issued in violation of the preemptive or similar rights
         of any securityholder of such Subsidiary.

                  (vii)    Capitalization. The authorized, issued and
         outstanding capital stock of the Company is as set forth in the
         Prospectus in the column entitled "Actual" under the caption
         "Capitalization" (except for subsequent issuances, if any, described
         therein and the issuance of the Securities pursuant to this
         Agreement). The shares of issued and outstanding capital stock of the
         Company have been duly authorized and validly issued and are fully
         paid and non-assessable; none of the outstanding shares of capital
         stock of the Company was issued in violation of the preemptive or
         other similar rights of any securityholder of the Company. 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 Time and, if later, as of each Date of Delivery, will be,
         complete and accurate in all material respects.

                  (viii)   Authorization of Agreement. This Agreement has been
         duly authorized, executed and delivered by the Company.


                                       5
<PAGE>   9


                  (ix)     Authorization and Description of Common Stock. The
         description of the Common Stock of the Company contained in the
         Prospectus conforms in all material respects to the rights set forth
         in the instruments defining the same.

                  (x)      Authorization and Description of Securities. The
         Securities have been duly authorized for issuance and sale to the
         Underwriters pursuant to this Agreement, and, when issued and
         delivered by the Company pursuant to this Agreement against payment of
         the consideration set forth herein will be validly issued and fully
         paid and non-assessable shares of capital stock of the Company; the
         description or the Securities contained in the Prospectus conforms in
         all material respects to the rights set forth in the instruments
         defining the same; no holder of the Securities will be subject to
         personal liability solely by reason of being such a holder; and the
         issuance of the Securities is not subject to the preemptive or other
         similar rights of any security holder of the Company.

                  (xi)     Absence of Defaults and Conflicts. Neither the
         Company nor any of its Subsidiaries is in violation of its articles of
         incorporation, charter or by-laws or in default in the performance or
         observance of any obligation, agreement, covenant or condition
         contained in any contract, indenture, mortgage, deed of trust, loan or
         credit agreement, note, lease or other agreement or instrument to
         which the Company or any of its Subsidiaries is a party or by which it
         or any of them may be bound, or to which any of the property or assets
         of the Company or any Subsidiary is subject (collectively, "Agreements
         and Instruments") except for such defaults that would not result in a
         Material Adverse Effect; and the execution, delivery and performance
         of this Agreement and the consummation of the transactions
         contemplated herein and in the Registration Statement (including the
         issuance and sale of the Securities and the use of the proceeds from
         the sale of the Securities as described in the Prospectus under the
         caption "Use of Proceeds") and compliance by the Company with its
         obligations hereunder have been duly authorized by all necessary
         corporate action and do not and will not, whether with or without the
         giving of notice or passage of time or both, conflict with or
         constitute a breach of, or default or Repayment Event (as defined
         below) under, or result in the creation or imposition of any lien,
         charge or encumbrance upon any property or assets of the Company or
         any Subsidiary pursuant to, the Agreements and Instruments (except for
         such conflicts, breaches or defaults or liens, charges or encumbrances
         that would not result in a Material Adverse Effect), nor will such
         action result in any violation of the provisions of the charter or
         by-laws of the Company or any Subsidiary or any applicable law,
         statute, rule, regulation, judgment, order, writ or decree of any
         government, government instrumentality or court, domestic or foreign,
         having jurisdiction over the Company or any Subsidiary or any of their
         assets, properties or operations. As used herein, a "Repayment
         Event" means any event or condition which gives the holder of any
         note, debenture or other evidence of indebtedness (or any person
         acting on such holder's behalf) the right to require the repurchase,
         redemption or repayment of all or a portion of such indebtedness by
         the Company or any Subsidiary.

                  (xii)    Absence of Labor Dispute. No labor dispute with the
         employees of the Company or any Subsidiary exists or, to the knowledge
         of the Company, is imminent. Neither the Company nor any Subsidiary is
         a party to a collective bargaining agreement.

                  (xiii)   Absence of Proceedings. There is no action, suit,
         proceeding, inquiry or investigation before or brought by any court or
         governmental agency or body, domestic or foreign, now pending, or, to
         the knowledge of the Company, threatened, against or affecting the
         Company or any Subsidiary, which is required to be disclosed in the
         Registration Statement (other than as disclosed therein), or which
         might reasonably be expected to result in a Material Adverse Effect,
         or which might reasonably be expected to materially and adversely
         affect the properties or assets thereof or the consummation of the
         transactions contemplated in this Agreement or the performance by the
         Company of its obligations hereunder; the aggregate of all pending
         legal or governmental proceedings to which the Company or any
         Subsidiary is a party or of which any of their respective property or
         assets is the subject which are not described in the Registration
         Statement, including ordinary routine litigation incidental to the
         business, could not reasonably be expected to result in a Material
         Adverse Effect.

                  (xiv)    Accuracy of Exhibits. There are no contracts or
         documents which are required to be described in the Registration
         Statement or the Prospectus (or if the Prospectus is not in existence,
         in the most recent preliminary prospectus) or to be filed as exhibits
         thereto which have not been so described and filed as required.

                  (xv)     Possession of Intellectual Property. The Company
         and its Subsidiaries own or possess, or can acquire on reasonable
         terms, adequate patents, patent rights, licenses, inventions,
         copyrights, know-how (including trade secrets and other unpatented
         and/or unpatentable proprietary or confidential information, systems
         or procedures), trademarks, service marks, trade names or other
         intellectual property (collectively, "Intellectual Property")
         necessary to carry on the business now operated by them, and neither
         the Company nor any of its Subsidiaries has received any actual notice
         or is otherwise aware of any infringement of or conflict with asserted
         rights of others with respect to any Intellectual Property or of any
         facts or circumstances which would render any Intellectual Property
         invalid or inadequate to protect the interest of the Company or any of
         its Subsidiaries therein, and which infringement or conflict (if the
         subject of any unfavorable decision, ruling or finding) or invalidity
         or inadequacy, singly or in the aggregate, would result in a Material
         Adverse Effect.

                  (xvi)    Absence of Further Requirements. No filing with, or
         authorization, approval, consent, license, order, registration,
         qualification or decree of, any court or governmental authority or
         agency is necessary or required for the performance by the Company of
         its obligations hereunder, in connection with the offering, issuance
         or sale of the Securities hereunder or the consummation of the
         transactions contemplated by this Agreement, except such as have been
         already obtained or as may be required under the 1933 Act or the 1933
         Act Regulations, state securities 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

         Company of the Certificate of Designation and Preferences with respect
         to the Securities with the Secretary of State of the Commonwealth of
         Puerto Rico ("Puerto Rico").

                  (xvii)   Possession of Licenses and Permits. The Company and
         its Subsidiaries possess such permits, licenses, approvals, consents
         and other authorizations (collectively, "Governmental Licenses")
         issued by the appropriate federal, state, Puerto Rico, local or
         foreign regulatory agencies or bodies necessary to conduct the
         business now operated by them, except where the lack of such
         Governmental Licenses would not, singly or in the aggregate, have a
         Material Adverse Effect; the Company and its Subsidiaries are in
         compliance with the terms and conditions of all such Governmental
         Licenses, except where the failure so to comply would not, singly or
         in the aggregate, have a Material Adverse Effect; all of the
         Governmental Licenses are valid and in full force and effect, except
         when the invalidity of such Governmental Licenses or the failure of
         such Governmental Licenses to be in full force and effect would not
         have a Material Adverse Effect; and neither the Company nor any of its
         Subsidiaries has received any notice of proceedings relating to the
         revocation or modification of any such Governmental Licenses which,
         singly or in the aggregate, if the subject of an unfavorable decision,
         ruling or finding, would result in a Material Adverse Effect.

                  (xviii)  Title to Property. The Company and its Subsidiaries
         have good and marketable title to all real property owned by the
         Company and its Subsidiaries and good title to all other properties
         and assets owned by them, in each case, free and clear of all
         mortgages, pledges, liens, security interests, claims, restrictions or
         encumbrances of any kind except such as (a) are described in the
         Prospectus or (b) would not, singly or in the aggregate, have a
         Material Adverse Effect; and all of the leases and subleases material
         to the business of the Company and its Subsidiaries, considered as one
         enterprise, and under which the Company or any of its Subsidiaries
         holds properties described in the Prospectus, are in full force and
         effect, and neither the Company nor any Subsidiary has any notice of
         any material claim of any sort that has been asserted by anyone
         adverse to the rights of the Company or any Subsidiary under any of
         the leases or subleases mentioned above, or affecting or questioning
         the rights of the Company or such Subsidiary to the continued
         possession of the leased or subleased premises under any such lease or
         sublease.

                  (xix)    Investment Company Act. The Company is not, and upon
         the issuance and sale of the Securities as herein contemplated and the
         application of the net proceeds therefrom as described in the
         Prospectus will not be, an "investment company" or an entity
         "controlled" by an "investment company" as such terms are defined in
         the Investment Company Act of 1940, as amended (the "1940 Act").

                  (xx)     Form S-3. The Company meets the requirements for use
         of Form S-3 under the 1933 Act Regulations.

                  (xxi)    Environmental Laws. To the knowledge of the Company,

         Subsidiaries and (D) there are no events or circumstances known to the
         Company that might reasonably be expected to form the basis of an
         order for clean-up or remediation, or an action, suit or proceeding by

         the Company or any of its Subsidiaries relating to Hazardous Materials
         or any Environmental Laws.

                  (xxii)   Registration Rights. There are no persons with
         registration rights or other similar rights to have any securities
         included in the offering described in the Registration Statement.

                  (xxiii)  Stop Orders. No court, supervisory or regulatory

         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 Closing Time and, if later,

         designed, or which might reasonably be expected in the future, to
         cause or result in, under the Act or otherwise, or which has

         or operations except as disclosed in the Prospectus (or if the
         Prospectus is not in existence, in the most recent preliminary
         prospectus).

         (b)      Officer's Certificates. Any certificate signed by any officer
of the Company or any of its Subsidiaries delivered to the Representatives or
to counsel for the Underwriters shall be deemed a representation and warranty
by the Company to the Underwriter as to the matters covered thereby.

         SECTION 2.        Sale and Delivery to Underwriters; Closing.

         (a)      Initial Securities. On the basis of the representations and
warranties herein contained and subject to the terms and conditions herein set
forth, the Company agrees to sell to each Underwriter, severally and not
jointly, and each Underwriter, severally and not jointly, agrees to purchase
from the Company, at the price per share set forth in Schedule B, the number of
Initial Securities set forth in Schedule A opposite the name of such
Underwriter, plus any additional number of Initial Securities which such
Underwriter may become obligated to purchase pursuant to the provisions of
Section 10 hereof.

         (b)      Option Securities. In addition, on the basis of the
representations and warranties herein contained and subject to the terms and
conditions herein set forth, the Company hereby grants an option to the
Underwriters, severally and not jointly, to purchase up to an additional
180,000 shares of the Company's ____% Noncumulative Monthly Income Preferred
Stock, Series A ($25 liquidation preference per share) at the price per share
set forth in Schedule B. The option hereby granted will expire 30 days after
the date hereof and may be exercised in whole or in part from time to time only
for the purpose of covering over-allotments which may be made in connection
with the offering and distribution of the Initial Securities upon notice by the
Representatives to the Company setting forth the number of Option Securities as
to which the several Underwriters are then exercising the option and the time
and date of payment and delivery for such Option Securities. Any such time and
date of delivery (a "Date of Delivery") shall be determined by the
Representatives, but shall not be later than seven full business days after the
exercise of said option, nor in any event prior to the Closing Time, as
hereinafter defined. If the option is exercised as to all or any portion of the
Option Securities, each of the Underwriters, acting severally and not jointly,
will purchase that proportion of the total number of Option Securities then
being purchased which the number of Initial Securities set forth in Schedule A
opposite the name of such Underwriter bears to the total number of Initial
Securities, subject in each case to such adjustments as the Representatives in
their discretion shall make to eliminate any sales or purchases of fractional
shares.

         (c)      Payment. Payment of the purchase price for, and delivery of
certificates for, the Initial Securities shall be made at the offices of
Pietrantoni Mendez & Alvarez, counsel to the Underwriters, Suite 1901, Popular
Center Building, San Juan, Puerto Rico 00918, or at such other place as shall
be agreed upon by the Representatives and the Company, at 9:00 A.M. (Eastern
time) on the third (fourth, if the pricing occurs after 4:30 P.M. (Eastern
time) on any given date) business day after the


                                      11
<PAGE>   15


date hereof (unless postponed in accordance with the provisions of Section 10),
or such other time not later than ten business days after such date as shall be
agreed upon by the Representatives and the Company (such time and date of
payment and delivery being herein called "Closing Time"). The Initial
Securities to be purchased by each Underwriter hereunder will be represented by
one or more definitive certificates registered in the name of Cede & Co., which
will be deposited by or on behalf of the Company with the Depository Trust
Company ("DTC") or its designated custodian.

         In addition, in the event that any or all of the Option Securities are
purchased by the Underwriters, payment of the purchase price for, and delivery
of certificates for, such Option Securities shall be made at the
above-mentioned offices, or at such other place as shall be agreed upon by the
Representatives and the Company, on each Date of Delivery as specified in the
notice from the Representatives to the Company.

         Payment shall be made to the Company by wire transfer of immediately
available funds to a bank account designated by the Company against delivery to
the Representatives for the respective accounts of the Underwriters of
certificates for the Securities to be purchased by them, duly endorsed for
transfer or by causing DTC to credit the Securities to the account of each
Underwriter in the case of the Initial Securities. It is understood that each
Underwriter has authorized the Representatives, for its account, to accept
delivery of, receipt for, and make payment of the purchase price for the
Initial Securities and the Option Securities, if any, which it has agreed to
purchase. Each Representative, individually and not as Representatives of the
Underwriters, may (but shall not be obligated to) make payment of the purchase
price for the Initial Securities and the Option Securities, if any, to be
purchased by any Underwriter whose funds have not been received by the Closing
Time or the relevant Date of Delivery, as the case may be, but such payment
shall not relieve such Underwriter from its obligations hereunder.

         (d)      Denominations; Registration. Certificates for the Initial
Securities and the Option Securities, if any, shall be in definitive form and
in such denominations and registered in such names as the Representatives may
request in writing at least one full business day before the Closing Time
or the relevant Date of Delivery, as the case may be. The certificates for the
Initial Securities and the Option Securities, if any, will be made available
for examination and packaging by the Representatives in San Juan, Puerto Rico
not later than 10:00 A.M. (Eastern time) on the business day prior to the
Closing Time or the relevant Date of Delivery, as the case may be at the office
of DTC or its designated custodian.

         (e)      Appointment of Qualified Independent Underwriter. The Company
hereby confirms its engagement of Keefe, Bruyette & Woods, Inc. ("Keefe
Bruyette") as, and Keefe Bruyette hereby confirms its agreement with the Company
to render services as, a "qualified independent underwriter" within the meaning
of Rule 2720 of the Conduct Rules of the NASD with respect to the offering and
sale of the Securities. Keefe Bruyette, solely in its capacity as qualified
independent underwriter and not otherwise, is referred to herein as the
"Independent Underwriter". The sale of the Securities shall be conducted
pursuant to Rule 2720(c) of the Conduct Rules of the NASD because Oriental
Financial Services Inc., a registered-broker and member of the NASD, is an
affiliate of the Company under the


                                      12
<PAGE>   16


Rule 2720 of the Conduct Rules of the NASD, and is participating as a member of
the selling group for the Securities.

         SECTION 3.        Covenants of the Company.  The Company covenants
with each Underwriter as follows:

                  (a)      Compliance with Securities Regulations and Commission
         Requests. The Company, subject to Section 3(b), will comply with the
         requirements of Rule 430A, and will notify the Representatives
         immediately, and confirm the notice in writing, (i) when any
         post-effective amendment to the Registration Statement shall become
         effective, or any supplement to the Prospectus or any amended
         Prospectus shall have been filed, (ii) of the receipt of any comments
         from the Commission, (iii) of any request by the Commission for any
         amendment to the Registration Statement or any amendment or supplement
         to the Prospectus or for additional information, and (iv) of the
         issuance by the Commission of any stop order suspending the
         effectiveness of the Registration Statement or of any order preventing
         or suspending the use of any preliminary prospectus, or of the
         suspension of the qualification of the Securities for offering or sale
         in any jurisdiction, or of the initiation or threatening of any
         proceedings for any of such purposes. The Company will promptly effect
         the filings necessary pursuant to Rule 424(b) and will take such steps
         as it deems necessary to ascertain promptly whether the form of
         prospectus transmitted for filing under Rule 424(b) was received for
         filing by the Commission and, in the event that it was not, it will
         promptly file such prospectus. The Company will make every reasonable
         effort to prevent the issuance of any stop order and, if any stop
         order is issued, to obtain the lifting thereof at the earliest
         possible moment.

                  (b)      Filing of Amendments. The Company will give the
         Representatives notice of its intention to file or prepare any
         amendment to the Registration Statement (including any filing under
         Rule 462(b)) or of any amendment, supplement or revision to either the
         prospectus included in the Registration Statement at the time it
         became effective or to the Prospectus, and will furnish the
         Representatives with copies of any such documents a reasonable amount
         of time prior to such proposed filing or use, as the case may be, and
         will not file or use any such document to which the Representatives or
         counsel for the Underwriters shall object.

                  (c)      Delivery of Registration Statements. The Company has
         furnished or will deliver to the Representatives and counsel for the
         Underwriters, without charge, signed copies of the Registration
         Statement as originally filed and of each amendment thereto (including
         exhibits filed therewith or incorporated by reference therein) and
         signed copies of all consents and certificates of experts, and will
         also deliver to the Representatives, without charge, a conformed copy
         of the Registration Statement as originally filed and of each
         amendment thereto (without exhibits) for each of the Underwriters. The
         copies of the Registration Statement and each amendment thereto
         furnished to the Underwriters will be identical to the electronically
         transmitted copies thereof filed with the Commission pursuant to
         EDGAR, except to the extent permitted by Regulation S-T.


                                      13

                  (d)      Delivery of Prospectuses. The Company has delivered
         to each Underwriter, without charge, as many copies of each
         preliminary prospectus as such Underwriter reasonably requested, and
         the Company hereby consents to the use of such copies for purposes
         permitted by the 1933 Act. The Company will furnish to each
         Underwriter, without charge, during the period when the Prospectus is
         required to be delivered under the 1933 Act or the 1934 Act, such
         number of copies of the Prospectus (as amended or supplemented) as
         such Underwriter may reasonably request. The Prospectus and any
         amendments or supplements thereto furnished to the Underwriters will
         be identical to the electronically transmitted copies thereof filed
         with the Commission pursuant to EDGAR, except to the extent permitted
         by Regulation S-T.

                  (e)      Continued Compliance with Securities Laws. The 
         Company will comply with the 1933 Act and the 1933 Act Regulations so
         as to permit the completion of the distribution of the Securities as
         contemplated in this Agreement and in the Prospectus. If at any time
         when a prospectus is required by the 1933 Act to be delivered in
         connection with sales of the Securities, any event shall occur or
         condition shall exist as a result of which it is necessary, in the
         opinion of counsel for the Underwriters or for the Company, to amend
         the Registration Statement or amend or supplement the Prospectus in
         order that the Prospectus will not include any untrue statements of a
         material fact or omit to state a material fact necessary in order to
         make the statements therein not misleading in the light of the
         circumstances existing at the time it is delivered to a purchaser, or
         if it shall be necessary, in the opinion of such counsel, at any such
         time to amend the Registration Statement or amend or supplement the
         Prospectus in order to comply with the requirements of the 1933 Act or
         the 1933 Act Regulations, the Company will promptly prepare and file
         with the Commission, subject to Section 3(b), such amendment or
         supplement as may be necessary to correct such statement or omission
         or to make the Registration Statement or the Prospectus comply with
         such requirements, and the Company will furnish to the Underwriters
         such number of copies of such amendment or supplement as the
         Underwriters may reasonably request.

                  (f)      Blue Sky Qualifications. The Company will use its
         best efforts, in cooperation with the Underwriters, to qualify the
         Securities for offering and sale under the applicable securities laws
         of such states and other jurisdictions as the Representatives may
         designate and to maintain such qualifications in effect for a period
         of not less than one year from the effective date of the Registration
         Statement and any Rule 462(b) Registration Statement; provided,
         however, that the Company shall not be obligated to file any general
         consent to service of process or to qualify as a foreign corporation
         or as a dealer in securities in any jurisdiction in which it is not so
         qualified or to subject itself to taxation in respect of doing
         business in any jurisdiction in which it is not otherwise so subject.
         In each jurisdiction in which the Securities have been so qualified,
         the Company will file such statements and reports as may be required
         by the laws of such jurisdiction to continue such qualification in
         effect for a period of not less than one year from the date of the
         Registration Statement and any Rule 462(b) Registration Statement.

                  (g)      Rule 158. The Company will timely file such reports
         pursuant to the 1934 Act as are necessary in order to make generally
         available to its securityholders as soon as practicable an earnings
         statement for the purposes of, and to provide the benefits
         contemplated by, the last paragraph of Section 11(a) of the 1933 Act.

                  (h)      Use of Proceeds. The Company will use the net 
         proceeds received by it from the sale of the Securities in the manner
         specified in the Prospectus under "Use of Proceeds".

                  (i)      Listing. The Company will use its best efforts to 
         effect the listing of the Securities on the New York Stock Exchange.

                  (j)      Restriction on Sale of Securities. During a period 
         of 90 days from the date of the Prospectus, the Company will not,
         without the prior written consent of the Representatives, (i) directly
         or indirectly, offer, pledge, sell, contract to sell, sell any option
         or contract to purchase, purchase any option or contract to sell,
         grant any option, right or warrant to purchase or otherwise transfer
         or dispose of any share of the Company's preferred stock (the
         "Preferred Stock") or any securities convertible into or exercisable
         or exchangeable for Preferred Stock or file any registration statement
         under the 1933 Act with respect to any of the foregoing or (ii) enter
         into any swap or any other agreement or any transaction that
         transfers, in whole or in part, directly or indirectly, the economic
         consequence of ownership of the Preferred Stock, whether any such swap
         or transaction described in clause (i) or (ii) above is to be settled
         by delivery of Preferred Stock or such other securities, in cash or
         otherwise. The foregoing sentence shall not apply to the Securities to
         be sold hereunder.

                  (k)      Reporting Requirements. The Company, during the 
         period when the Prospectus is required to be delivered under the 1933
         Act or the 1934 Act, will file all documents required to be filed with
         the Commission pursuant to the 1934 Act within the time periods
         required by the 1934 Act and the rules and regulations of the
         Commission thereunder.

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

                  (m)      Additional Information. During a period of five years
         commencing on the date the Registration Statement is declared
         effective by the Commission, the Company will furnish to the
         Representatives 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
         Representatives 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.

         SECTION 4.        Payment of Expenses. (a) Expenses. The Company will

         (b)      Termination of Agreement.  If this Agreement is terminated by

         SECTION 5.        Conditions of Underwriters' Obligations. The 
obligations of the several Underwriters hereunder are subject to the accuracy

                  (a)      Effectiveness of Registration Statement. The

         change in the condition, financial or otherwise, or in the earnings,
         business affairs or business prospects of the Company and its
         Subsidiaries considered as one enterprise, whether or not arising in
         the ordinary course of business, and the Representatives shall have
         received a certificate of the President or a Vice President of the
         Company and of the chief financial or chief accounting officer of the
         Company, dated as of Closing Time, to the effect that (i) there has
         been no Material Adverse Effect, (ii) the representations and
         warranties in Section 1(a) hereof are true and correct with the same
         force and effect as though expressly made at and as of Closing Time,

         Underwriters, containing statements and information of the type
         ordinarily included in accountants' "comfort letters" to underwriters
         with respect to the financial statements and certain financial
         information contained in the Registration Statement and the
         Prospectus.

                  (f)      Bring-down Comfort Letter. At Closing Time, the

         any preliminary prospectus or the Prospectus (or any amendment or
         supplement thereto), or the omission or alleged omission therefrom of
         a material fact necessary in order to make the statements therein, in
         the light of the circumstances under which they were made, not

                           (ii)     against any and all loss, liability, claim,
         damage and expense whatsoever, as incurred, to the extent of the
         aggregate amount paid in settlement of any litigation, or any
         investigation or proceeding by any governmental agency or body,
         commenced or threatened, or of any claim whatsoever based upon any
         such untrue statement or omission, or any such alleged untrue
         statement or omission; provided that (subject to Section 6(d) below)
         any such settlement is effected with the written consent of the
         Company; and

                           (iii)    against any and all expense whatsoever, as
         incurred (including the fees and disbursements of counsel chosen by
         the Representatives), reasonably incurred in investigating, preparing
         or defending against any litigation, or any investigation or
         proceeding by any governmental agency or body, commenced or
         threatened, or any claim whatsoever based upon any such untrue
         statement or omission, or any such alleged untrue statement or
         omission, to the extent that any such expense is not paid under (i) or
         (ii) above;

provided, however, that this indemnity agreement shall not apply to any loss,
liability, claim, damage or expense to the extent arising out of any untrue
statement


                                      19
<PAGE>   23


or omission or alleged untrue statement or omission made in reliance upon and
in conformity with written information furnished to the Company by any
Underwriter through the Representatives expressly for use in the Registration
Statement (or any amendment thereto), including the Rule 430A Information, or
any preliminary prospectus or the Prospectus (or any amendment or supplement
thereto).

                  (2)      In addition to and without limitation of the 
Company's obligation to indemnify Keefe Bruyette, as an Underwriter, the
Company also agrees to indemnify and hold harmless the Independent Underwriter
and each person, if any, who controls the Independent Underwriter within the
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act from and
against any and all loss, liability, claim, damage, and expense whatsoever, as
incurred, incurred as a result of the Independent Underwriter's participation as
a "qualified independent underwriter" within the meaning of Rule 2720 of the
Conduct Rules of the NASD in connection with the offering of the Securities.

         (b)      Indemnification of Company, Directors and Officers by
Underwriters. Each Underwriter severally agrees to indemnify and hold harmless
the Company, its directors, each of its officers who signed the Registration
Statement, and each person, if any, who controls the Company within the meaning
of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all
loss, liability, claim, damage and expense described in the indemnity contained
in subsection (a)(1) of this Section, as incurred, but only with respect to
untrue statements or omissions, or alleged untrue statements or omissions, made
in the Registration Statement (or any amendment thereto), including the Rule
430A Information, or any preliminary prospectus or the Prospectus (or any
amendment or supplement thereto) in reliance upon and in conformity with
written information furnished to the Company by such Underwriter through the
Representatives expressly for use in the Registration Statement (or any
amendment thereto) or such preliminary prospectus or the Prospectus (or any
amendment or supplement thereto). The Company acknowledges that, for all
purposes of this Agreement, the amounts of the selling concession and
reallowance set forth under the heading "Underwriting" contained in the
Prospectus constitute the only information relating to any Underwriter
furnished in writing to the Company expressly for inclusion in the preliminary
prospectus, the Registration Statement (or any amendment thereto) or the
Prospectus (or any amendment or supplement thereto).

         (c)      Actions against Parties; Notification. Each indemnified party
shall give notice as promptly as reasonably practicable to each indemnifying
party of any action commenced against it in respect of which indemnity may be
sought hereunder, but failure to so notify an indemnifying party shall not
relieve such indemnifying party from any liability hereunder to the extent it
is not materially prejudiced as a result thereof and in any event shall not
relieve it from any liability which it may have otherwise than on account of
this indemnity agreement. In the case of parties indemnified pursuant to
Sections 6(a)(1) above, counsel to the indemnified parties shall be selected by
the Representatives, and, in the case of parties indemnified pursuant to
Section 6(b) above, counsel to the indemnified parties shall be selected by the
Company. An indemnifying party may participate at its own expense in the
defense of any such action; provided, however, that counsel to the indemnifying
party shall not (except with the consent of the indemnified party) also be
counsel to the indemnified party. In no event shall the indemnifying parties be
liable for fees and expenses of more than one counsel (in addition to any local
counsel) separate from their own counsel for all indemnified parties in


                                      20
<PAGE>   24


connection with any one action or separate but similar or related actions in
the same jurisdiction arising out of the same general allegations or
circumstances; provided, that, if indemnity is sought pursuant to Section
6(a)(2), then, in addition to the fees and expenses of such counsel for the
indemnified parties, the indemnifying party shall be liable for the reasonable
fees and expenses of not more than one counsel (in addition to any local
counsel) separate from its own counsel and that of the other indemnified
parties for the Independent Underwriter in its capacity as a "qualified
independent underwriter" and all persons, if any, who control the Independent
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
1934 Act in connection with any one action or separate but similar or related
actions in the same jurisdiction arising out of the same general allegations or
circumstances if, in the reasonable judgment of the Independent Underwriter,
there may exist a conflict of interest between the Independent Underwriter and
the other indemnified parties. Any such separate counsel for the Independent
Underwriter and such control persons of the Independent Underwriter shall be
designated in writing by the Independent Underwriter. No indemnifying party
shall, without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution could be sought under this Section 6 or Section
7 hereof (whether or not the indemnified parties are actual or potential
parties thereto), unless such settlement, compromise or consent (i) includes an
unconditional release of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim and (ii) does not
include a statement as to or an admission of fault, culpability or a failure to
act by or on behalf of any indemnified party.

         (d)      Settlement without Consent if Failure to Reimburse. If at any
time an indemnified party shall have requested an indemnifying party to
reimburse the indemnified party for fees and expenses of counsel, such
indemnifying party agrees that it shall be liable for any settlement of the
nature contemplated by Sections 6(a)(1)(ii) effected without its written
consent if (i) such settlement is entered into more than 45 days after receipt
by such indemnifying party of the aforesaid request, (ii) such indemnifying
party shall have received notice of the terms of such settlement at least 30
days prior to such settlement being entered into and (iii) such indemnifying
party shall not have reimbursed such indemnified party in accordance with such
request prior to the date of such settlement.

         SECTION 7.        Contribution. If the indemnification provided for in
Section 6 hereof is for any reason unavailable to or insufficient to hold
harmless an indemnified party in respect of any losses, liabilities, claims,
damages or expenses referred to therein, then each indemnifying party shall
contribute to the aggregate amount of such losses, liabilities, claims, damages
and expenses incurred by such indemnified party, as incurred, (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the Underwriters on the other hand from the
offering of the Securities pursuant to this Agreement or (ii) if the allocation
provided by clause 7(i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause 7(i) above but also the relative fault of the Company on the one
hand and of the Underwriters on the other hand in connection with the
statements or omissions which resulted in such losses, liabilities, claims,
damages or expenses, as well as any other relevant equitable considerations.


                                      21
<PAGE>   25


         The relative benefits received by the Company on the one hand and the
Underwriters on the other hand in connection with the offering of the
Securities pursuant to this Agreement shall be deemed to be in the same
respective proportions as the total net proceeds from the offering of the
Securities pursuant to this Agreement (before deducting expenses) received by
the Company and the total underwriting discount received by the Underwriters,
in each case as set forth on the cover of the Prospectus, bear to the aggregate
initial public offering price of the Securities as set forth on such cover.

         The relative fault of the Company on the one hand and the Underwriters
on the other hand shall be determined by reference to, among other things,
whether any such untrue or alleged untrue statement of a material fact or
omission or alleged omission to state a material fact relates to information
supplied by the Company or by the Underwriters and 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 Keefe Bruyette will not
receive any additional benefits hereunder for serving as the Independent
Underwriter in connection with the offering and sale of the securities.

         The Company and the Underwriters agree that it would not be just and
equitable if contribution pursuant to this Section 7 were 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 account of
the equitable considerations referred to above in this Section 7. The aggregate
amount of losses, liabilities, claims, damages and expenses incurred by an
indemnified party and referred to above in this Section 7 shall be deemed to
include, subject to the limitations set forth above, any legal or other
expenses reasonably incurred by such indemnified party in investigating,
preparing or defending against any litigation, or any investigation or
proceeding by any governmental agency or body, commenced or threatened, or any
claim whatsoever based upon any such untrue or alleged untrue statement or
omission or alleged omission.

         Notwithstanding the provisions of this Section 7, no Underwriter shall
be required to contribute any amount in excess of the amount by which the total
price at which the Securities underwritten by it and distributed to the public
were offered to the public exceeds the amount of any damages which such
Underwriter has otherwise been required to pay by reason of such untrue or
alleged untrue statement or omission or alleged omission.

         No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the 1933 Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

         For purposes of this Section 7, each person, if any, who controls an
Underwriter within the meaning of Section 15 of the 1933 Act or Section 20 of
the 1934 Act shall have the same rights to contribution as such Underwriter,
and each director of the Company and each person, if any, who controls the
Company within the meaning of Section 15 of the 1933 Act or Section 20 of the
1934 Act shall have the same rights to contribution as the Company. The
Underwriters' respective


                                      22
<PAGE>   26


obligations to contribute pursuant to this Section 7 are several in proportion
to the number of Securities set forth opposite their respective names in
Schedule A hereto and not joint.

         SECTION 8.        Representations, Warranties and Agreements to 
Survive Delivery. All representations, warranties and agreements contained in
this Agreement or in certificates of officers of the Company and its
Subsidiaries submitted pursuant hereto, shall remain operative and in full
force and effect, regardless of any investigation made by or on behalf of any
Underwriter or controlling person, or by or on behalf of the Company and shall
survive delivery of the Securities to the Underwriters.

         SECTION 9         Termination of Agreement.

                  (a)      Termination; General. The Representatives may 
terminate this Agreement, by notice to the Company, at any time at or prior to
Closing Time (and with respect to Option Securities, any applicable Date of
Delivery) (i) if there has been, since the time of execution of this Agreement
or since the respective dates as of which information is given in the
Prospectus, any material adverse change in the condition, financial or
otherwise, or in the earnings, business affairs or business prospects of the
Company and its Subsidiaries considered as one enterprise, whether or not
arising in the ordinary course of business, or (ii) if there has occurred any
material adverse change in the financial markets in the United States or the
international financial markets, any outbreak of hostilities or escalation
thereof or other calamity or crisis or any change or development involving a
prospective change in national or international political, financial or
economic conditions, in each case the effect of which is such as to make it, in
the judgment of the Representatives, impracticable to market the Securities or
to enforce contracts for the sale of the Securities, or (iii) if trading in any
securities of the Company has been suspended or materially limited by the
Commission or the New York Stock Exchange, or if trading generally on the
American Stock Exchange or the New York Stock Exchange or in the Nasdaq
National Market has been suspended or materially limited, or minimum or maximum
prices for trading have been fixed, or maximum ranges for prices have been
required, by any of said exchanges or by such system or by the order of the
Commission, the NASD or any other governmental authority or (iv) if a banking
moratorium has been declared by Federal, New York or Puerto Rican authorities.

                  (b)      Liabilities. If this Agreement is terminated pursuant
to this Section, such termination shall be without liability of any party to
any other party except as provided in Section 4 hereof, and provided further
that Sections 1, 6, 7 and 8 shall survive such termination and remain in full
force and effect.

         SECTION 10.       Default by One or More of the Underwriters. If one or
more of the Underwriters shall fail or refuse at Closing Time or at a Date of
Delivery to purchase the Securities which it or they are obligated to purchase
under this Agreement (the "Defaulted Securities"), the Representatives shall
have the right, within 24 hours thereafter, to make arrangements for one or
more of the non-defaulting Underwriters, or any other underwriters, to purchase
all, but not less than all, of the Defaulted Securities in such amounts as may
be agreed upon and upon the terms herein set


                                      23
<PAGE>   27


forth; if, however, the Representatives shall not have completed such
arrangements within such 24-hour period, then:

                  (a)      if the number of Defaulted Securities does not exceed
10% of the number of Securities to be purchased on such date, each of the
non-defaulting Underwriters shall be obligated, severally and not jointly, to
purchase the full amount thereof in the proportions that their respective
underwriting obligations hereunder bear to the underwriting obligations of all
non-defaulting Underwriters, or

                  (b)      if the number of Defaulted Securities exceeds 10% of
the number of Securities to be purchased on such date and arrangements
satisfactory to the remaining Underwriters and the Company for the purchase of
such shares are not made within 36 hours of such default, this Agreement, or
with respect to any Date of Delivery which occurs after the Closing Time, the
obligation of the Underwriters to purchase and of the Company to sell the
Option Securities to be purchased and sold on such Date of Delivery, shall
terminate without liability on the part of any non-defaulting Underwriter or
the Company.

         In the event of any such default which does not result in a
termination of this Agreement or, in the case of a Date of Delivery which is
after the Closing Time, which does not result in a termination of the
obligation of the Underwriters to purchase and the Company to sell the relevant
Option Securities, as the case may be, either the Representatives or the
Company shall have the right to postpone Closing Time or the relevant Date of
Delivery, as the case may be, for a period not exceeding seven days in order to
effect any required changes in the Registration Statement or Prospectus or in
any other documents or arrangements. As used herein, the term "Underwriter"
includes any person substituted for an Underwriter under this Section 10.

         No action taken pursuant to this Section shall relieve any defaulting
Underwriter from liability in respect of its default.

         SECTION 11.       Notices.  All notices and other communications
hereunder shall be in writing and shall be deemed to have been duly given if
mailed or transmitted by any standard form of telecommunication. Notices to the
Underwriters shall be directed to the Representatives at Santander Securities
Corporation of Puerto Rico, Torre Santander, 221 Avenida Ponce de Leon, Suite

Banking, to Keefe, Bruyette & Woods, Inc. at __________________, Attention:

Rey Tower, Suite 503, 268 Munoz Rivera Avenue, Hato Rey, Puerto Rico 00918,
Attention: President.

         SECTION 12.       Parties. This Agreement shall inure to the benefit
of and be binding upon the Underwriters, the Company and their respective
successors. Nothing expressed or mentioned in this Agreement is intended or
shall be construed to give any person, firm or corporation, other than the
Underwriters and the Company and their respective successors and the
controlling persons and officers and directors referred to in Sections 6 and 7
and their heirs and legal representatives, any


                                      24
<PAGE>   28


legal or equitable right, remedy or claim under or in respect of this Agreement
or any provision herein contained. This Agreement and all conditions and
provisions hereof are intended to be for the sole and exclusive benefit of the
Underwriters and the Company and their respective successors, and said
controlling persons and officers and directors and their heirs and legal
representatives, and for the benefit of no other person, firm or corporation.
No purchaser of Securities from any Underwriter shall be deemed to be a
successor by reason merely of such purchase.

         SECTION 13.       GOVERNING LAW AND TIME.  THIS AGREEMENT SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF PUERTO
RICO.  EXCEPT AS OTHERWISE SET FORTH HEREIN, SPECIFIED TIMES OF DAY REFER
TO PUERTO RICO TIME.

         SECTION 14.       Effect of Headings.  The Article and Section 
headings herein and the Table of Contents are for convenience only and shall
not affect the construction hereof.

         SECTION 15.       Counterparts.  This Agreement may be executed in two
or more counterparts, each of which shall be deemed an original, but all of
which together shall constitute one and the same instrument.

         If the foregoing is in accordance with your understanding of our
agreement, please sign and return to the Company a counterpart hereof,
whereupon this instrument, along with all counterparts, will become a binding
agreement among the Underwriters and the Company in accordance with its terms.

                                         Very truly yours,

                                  SECTION 5(C)



                  (i)      The Company has been duly incorporated and is validly
         existing as a corporation in good standing under the laws of the
         Commonwealth of Puerto Rico, and has corporate power and authority to
         own, lease and operate its properties and to conduct its business as
         described in the Prospectus.

                  (ii)     Each of the Subsidiaries has been duly incorporated
         and is validly existing as a corporation (and in the case of the Bank
         as a commercial bank) in good standing under the laws of the
         Commonwealth of Puerto Rico, and has corporate power and authority to
         own, lease and operate its properties and to conduct its business as
         described in the Prospectus.

                  (iii)    The Company is registered as a bank holding company
         under the Bank Holding Company Act of 1956.

                  (iv)     The Company has corporate power and authority to own,
         lease and operate its properties and to conduct its business as
         described in the Prospectus.

                  (v)      The Company is duly qualified as a foreign
         corporation to transact business in each jurisdiction in which such
         qualification is required, whether by reason of the ownership or
         leasing of property or the conduct of business, except where the
         failure so to qualify would not result in a Material Adverse Effect.

                  (vi)     The authorized, issued and outstanding capital stock
         of the Company is as set forth in the Prospectus in the column
         entitled "Actual" under the caption "Capitalization" (except for
         subsequent issuances, if any, pursuant to the Underwriting Agreement
         or pursuant to reservations, agreements or employee benefit plans
         referred to in the Prospectus or pursuant to the exercise of
         convertible securities or options referred to in the Prospectus); the
         shares of issued and outstanding capital stock of the Company have
         been duly authorized and validly issued and are fully paid and
         non-assessable; and none of the outstanding shares of capital stock of
         the Company was issued in violation of the preemptive or other similar
         rights of any security holder of the Company.

                  (vii)    The Securities have been duly authorized for issuance
         and sale to the Underwriters pursuant to the Underwriting Agreement
         and, when issued and delivered by the

         Company pursuant to the Underwriting Agreement against payment of the
         consideration set forth in the Underwriting Agreement, will be validly
         issued and fully paid and non-assessable; no holder of the Securities
         is or will be subject to personal liability for obligations of the
         Company solely by reason of being such a holder; the Securities
         conform to the provisions of the certificate of designation of the
         Company creating the Securities (the "Certificate of Designation") and
         the rights, preferences and other terms of the Securities are as set
         forth in the Certificate of Designation relating thereto, and all such
         provisions are valid under the laws of the Commonwealth of Puerto
         Rico.

                  (viii)   The issuance of the Securities is not subject to the
         preemptive or other similar rights of any security holder of the
         Company.

                  (ix)     Each Subsidiary has been duly incorporated and is
         validly existing as a corporation (and in the case of the Bank, as a
         commercial bank) in good standing under the laws of the Commonwealth
         of Puerto Rico, has corporate power and authority to own, lease and
         operate its properties and to conduct its business as described in the
         Prospectus, and each Subsidiary is duly qualified as a foreign
         corporation to transact business in each jurisdiction in which such
         qualification is required, whether by reason of the ownership or
         leasing of property or the conduct of business, except where the
         failure so to qualify would not result in a Material Adverse Effect;
         except as otherwise disclosed in the Registration Statement, has been
         duly authorized and validly issued, is fully paid and non-assessable
         and, to the best of our knowledge, is owned by the Company, directly
         or through a Subsidiary, free and clear of any security interest,
         mortgage, pledge, lien, encumbrance, claim or equity; and none of the
         outstanding shares of capital stock of any Subsidiary was issued in
         violation of the preemptive or similar rights of any security holder
         of any Subsidiary.

                  (x)      The Company has full legal right, power, and
         authority to enter into the Underwriting Agreement and to consummate
         the transactions provided for therein. The Underwriting Agreement has
         been duly authorized, executed and delivered by the Company, and
         assuming due authorization, execution and delivery by each other party
         thereto, 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
         Puerto Rico securities laws or the public policy underlying such laws.

                  (xi)     The Registration Statement has been declared
         effective under the 1933 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 of our
         knowledge, 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 has been issued under the 1933 Act and no proceedings for
         that purpose have been instituted or are pending or threatened by the
         Commission.

                  (xii)    The Registration Statement, the Rule 430A
         Information, the Prospectus and each amendment or supplement to the
         Registration Statement and Prospectus, and the documents incorporated
         therein by reference, as of their respective filing, effective or
         issue dates, as the case may be (other than the financial statements,
         notes to the financial statements, financial tables and other
         financial information and supporting schedules included therein or
         omitted therefrom or contained in the documents incorporated by
         reference therein, as to which we need express no opinion), complied
         as to form in all material respects with the requirements of the 1933
         Act and the 1933 Act Regulations and, in the case of the documents
         incorporated by reference, the 1934 Act and the rules and regulations
         of the Commission thereunder.

                  (xiii)   The form of certificate used to evidence the
         Securities complies in all material respects with all applicable
         Commonwealth of Puerto Rico statutory requirements, with any
         applicable requirements of the Certificate of Incorporation and
         By-laws of the Company and the requirements of the New York Stock
         Exchange. The Securities have been duly authorized for listing on the
         New York Stock Exchange.

                  (xiv)    To the best of our knowledge, there is not pending
         or threatened any action, suit, proceeding, inquiry or investigation,
         to which the Company or any Subsidiary is a party, or to which the
         property or assets of the Company or any Subsidiary is subject, before
         or brought by any court or governmental agency or body, domestic or
         foreign, of a character required to be disclosed in the Registration
         Statement or the Prospectus which is not so disclosed therein, which
         might reasonably be expected to result in a Material Adverse Effect,
         or which might reasonably be expected to materially and adversely
         affect the properties or assets thereof or the consummation of the
         transactions contemplated in the Underwriting Agreement or the
         performance by the Company of its obligations thereunder.

                  (xv)     The information in the Prospectus under "Risk
         Factors--Payment of Dividends", "Risk Factors--Holding Company
         Structure", "Description of Series A Preferred Stock", "Description of
         Capital Stock", "Taxation-United States Taxation", "Taxation-Puerto
         Rico Taxation" and in the Registration Statement under Item 15, to the
         extent that it constitutes a discussion of federal or Puerto Rico law,
         summaries of legal matters involving federal or Puerto Rico law, the
         Company's Certificate of Incorporation and By-laws or legal
         proceedings, or legal conclusions, has been reviewed by us and is
         accurate and complete in all material respects; and our opinion set
         forth under "Taxation" is confirmed. The Securities conform as to
         legal matters in all material respects to the descriptions thereof in
         the Prospectus.

                  (xvi)    To the best of our knowledge, there are no statutes
         or regulations that are required to be described in the Prospectus
         that are not described as required.

                  (xvii) All descriptions in the Registration Statement of
         contracts and other documents to which the Company or its Subsidiaries
         are a party are accurate in all material respects; to the best of our
         knowledge, there are no franchises, contracts, indentures,


                                      B-3
<PAGE>   36


         mortgages, loan agreements, notes, leases or other instruments
         required to be described or referred to in the Registration Statement
         or to be filed as exhibits thereto other than those described or
         referred to therein or filed or incorporated by reference as exhibits
         thereto, and the descriptions thereof or references thereto are
         correct in all material respects.

                  (xviii)  To the best of our knowledge, neither the Company
         nor any Subsidiary is in violation of its articles of incorporation or
         by-laws and no default by the Company or any Subsidiary exists in the
         due performance or observance of any material obligation, agreement,
         covenant or condition contained in any contract, indenture, mortgage,
         loan agreement, note, lease or other agreement or instrument that is
         described or referred to in the Registration Statement or the
         Prospectus or filed or incorporated by reference as an exhibit to the
         Registration Statement.

                  (xix)    No filing with, or authorization, approval, consent,
         license, order, registration, qualification or decree of, any court or
         governmental authority or agency, domestic or foreign (other than
         under the 1933 Act and the 1933 Act Regulations, which have been
         obtained, the filing of the Certificate of Designation with the Puerto
         Rico Department of State which has been made, or as may be required
         under the securities or blue sky laws of the various states, as to
         which blue sky laws we express no opinion) is necessary or required in
         connection with the due authorization, execution and delivery of the
         Underwriting Agreement or for the offering, issuance, sale or delivery
         of the Securities.

                  (xx)     The execution, delivery and performance of the
         Underwriting Agreement and the consummation of the transactions
         contemplated in the Underwriting Agreement and in the Registration
         Statement (including the issuance and sale of the Securities and the
         use of the proceeds from the sale of the Securities as described in
         the Prospectus under the caption "Use of Proceeds") and compliance by
         the Company with its obligations under the Underwriting Agreement do
         not and will not, whether with or without the giving of notice or
         lapse of time or both, conflict with or constitute a breach of, or
         default or Repayment Event (as defined in Section 1(a)(xi) of the
         Underwriting Agreement) under or result in the creation or imposition
         of any lien, charge or encumbrance upon any property or assets of the
         Company or any Subsidiary pursuant to any contract, indenture,
         mortgage, deed of trust, loan or credit agreement, note, lease or any
         other agreement or instrument, known to us, to which the Company or
         any Subsidiary is a party or by which it or any of them may be bound,
         or to which any of the property or assets of the Company or any
         Subsidiary is subject (except for such conflicts, breaches or defaults
         or liens, charges or encumbrances that would not have a Material
         Adverse Effect), nor will such action result in any violation of the
         provisions of the articles of incorporation or by-laws of the Company
         or any Subsidiary, or any applicable law, statute, rule, regulation,
         judgment, order, writ or decree, known to us, of any government,
         government instrumentality or court, domestic or foreign, having
         jurisdiction over the Company or any Subsidiary or any of their
         respective properties, assets or operations.

                  (xxi)    To the best of our knowledge, there are no persons
         with registration rights or other similar rights to have any
         securities registered pursuant to the Registration Statement or
         otherwise registered by the Company under the 1933 Act.

                  (xxii)   The Company is not, and upon the issuance and sale
         of the Securities as contemplated in the Underwriting Agreement and
         the application of the net proceeds therefrom as described in the
         Prospectus will not be, an "investment company" or an entity
         "controlled" by an "investment company," as such terms are defined in
         the 1940 Act.

                  (xxiii)  The deposit accounts of the Bank are insured by the
         FDIC to the legal maximum, and to the best of our knowledge, no
         proceeding for the termination or revocation of such insurance is
         pending or threatened. The Bank is a member of the Federal Home Loan
         Bank of New York.

                  (xxiv)   To the best of our knowledge, none of the Company,
         its Subsidiaries, or any of their respective directors or officers is
         subject to any order or directive of, or is a party to any agreement
         with, any federal or Puerto Rico securities, banking or mortgage
         banking regulatory agency having jurisdiction with respect to the
         business or operations of the Company or the Subsidiaries except as
         disclosed in the Registration Statement or the Prospectus and except
         for any such order, directive or agreement which would not have a
         Material Adverse Effect.

                  (xxv)    To the best of our knowledge, the conduct of the
         respective businesses of the Company and its Subsidiaries is not in
         violation of any federal or Puerto Rico banking, mortgage banking or
         securities law, which violation is likely to have a Material Adverse
         Effect. Each of the Company and the Subsidiaries has obtained and, to
         our knowledge, is operating in compliance with, all authorizations,
         licenses, orders and directives required by federal and Puerto Rico
         banking, mortgage banking or securities laws which are material to the
         conduct of their respective businesses. To our knowledge, all such
         authorizations, licenses, orders or directives are valid and in full
         force and effect and neither the Company nor the Subsidiaries have
         received any notice of any proceeding relating to the revocation or
         modification of any such license, authorization or order.

         Nothing has come to our attention that would lead us to believe that
the Registration Statement or any amendment thereto, including the documents
incorporated therein by reference and the Rule 430A Information (except for
financial statements, notes to the financial statements, financial tables and
other financial information and schedules and other financial data included
therein or omitted therefrom or contained in the documents incorporated therein
by reference, as to which we need make no statement), at the time such
Registration Statement or any such amendment became effective, contained an
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 or any amendment or supplement thereto
(except for financial statements, notes to the financial statements, financial
tables and other financial information and schedules and other financial data
included therein or omitted therefrom or contained in the documents therein
incorporated by


                                      B-5
<PAGE>   38


reference, as to which we need make no statement), at the time the Prospectus
was issued, at the time any such amended or supplemented prospectus was issued
or at the Closing Time, included or includes an untrue statement of a material
fact or omitted or omits 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.

         In rendering such opinion, such counsel may rely as to matters of fact
(but not as to legal conclusions), to the extent they deem proper, on
certificates of responsible officers of the Company and public officials. Such
opinion shall not state that it is to be governed or qualified by, or that it
is otherwise subject to, any treatise, written policy or other document
relating to legal opinions, including, without limitation, the Legal Opinion
Accord of the ABA Section of Business Law (1991).

         FOURTH:  The authorized capital of the Corporation shall be FORTY FIVE
MILLION DOLLARS ($45,000,000) represented by FORTY MILLION (40,000,000) shares
of common stock, $1.00 par value per share, and FIVE MILLION (5,000,000) shares
of preferred stock, $1.00 par value per share. The shares may be issued by the
Corporation from time to time as authorized by the Board of Directors without
the further approval of shareholders, except to the extent that such approval is
required by governing law, rule or regulation.

         The Board of Directors is expressly authorized to provide, when it
deems necessary, for the issuance of shares of preferred stock in one or more
series, with such voting powers, full or limited, but not to exceed one vote per
share, or without voting powers; and with such designations, preferences,
rights, qualifications, limitations or restrictions thereof, as shall be
expressed in the resolution or resolutions of the Board of Directors,
authorizing such issuance, including (but without limiting the generality of the
foregoing) the following:

                  (a)      the designation of such series, the number of shares 
to constitute such series and the stated value thereof if different from the par
value thereof;

                  (b)      the dividend rate of such series, the conditions and

         (d)      the terms and amount of any sinking fund provided for the

         The powers, preferences and relative, participating, optional and other

limitations or restrictions thereof, if any, may differ from those of any and
all other series at any time outstanding. All shares of any one series of
preferred stock shall be identical in all respects with all other shares of such
series, except that shares of any one series issued at different times may
differ as to the dates from which dividends thereon shall accrue and/or be
cumulative.

         FIFTH:   No holder of the capital stock of the Corporation shall be
entitled as such, as a matter of right, to subscribe for or purchase any part of
any new or additional issue of stock of any class whatsoever of the Corporation,
or of securities convertible into stock of any class whatsoever, whether now or
hereafter authorized, or whether issued for cash or other consideration or by
way of a dividend.

         SEVENTH: The Corporation is to have perpetual existence.

         EIGHTH:  For the management of the business and for the conduct of the
affairs of the Corporation, and in further creation, definition, limitation and
regulation of the powers of the Corporation and of its directors and
stockholders, it is further provided:

         1.       DIRECTORS AND NUMBER OF DIRECTORS. The business and affairs of
the Corporation shall be managed by or under the direction of a Board of
Directors. The number of directors of the Corporation shall be fixed by, or in
the manner provided in, the by-laws. The directors of the Corporation need not
be stockholders.

         2.       CLASSIFICATION AND TERM. The Board of Directors, other than 
those who may be elected by the holders of any class or series of stock having
preference over the Common Stock as to dividends or upon liquidation, shall be
divided into three classes as nearly equal in number as possible, with one class
to be elected annually. The term of office of the initial directors shall be as
follows: the term of directors of the first class shall expire at the first
annual meeting of stockholders after the effective date of this Certificate of
Incorporation; the term of office of the directors of the second class shall
expire at the second annual meeting of stockholders after the effective date of
this Certificate of Incorporation; and the term of office of the third class
shall expire at the third annual meeting of stockholders after the effective
date of this Certificate of Incorporation; and, as to directors of each class,
when their respective successors are elected and qualified. At each annual
meeting of stockholders, directors elected to succeed those whose terms are
expiring shall be elected for a term of office to expire at the third succeeding
annual meeting of stockholders and when their respective successors are elected
and qualified.

         3.       CUMULATIVE VOTING. At each annual meeting of stockholders in 
which more than one director is being elected, every stockholder entitled 


<PAGE>   4

                                       4


to vote at such election shall have the right to vote, in person or by proxy,
the number of shares owned by the stockholder for as many persons as there are
directors to be elected and for whose election the stockholder has a right to
vote, or to cumulate the votes by giving one candidate as many votes as the
number of such directors to be elected multiplied by the number of his shares
shall equal, or by distributing such votes on the same principle among any
number of candidates.

         4.       VACANCIES. Except as otherwise fixed pursuant to the 
provisions of Article FOURTH hereof relating to the rights of the holders of any
class or series of stock having a preference over the Common Stock as to
dividends or upon liquidation to elect directors, any vacancy occurring in the
Board of Directors, including any vacancy created by reason of an increase in
the number of directors, may be filled by a majority vote of the directors then
in office, whether or not a quorum is present, or by a sole remaining director,
and any director so chosen shall hold office for the remainder of the term to
which the director has been selected and until such director's successor shall
have been elected and qualified. When the number of directors is changed, the
Board of Directors shall determine the class or classes to which the increased
or decreased number of directors shall be apportioned; provided that no decrease
in the number of directors shall shorten the term of any incumbent director.

         5.       REMOVAL. Subject to the rights of any class or series of stock
having preference over the Common Stock as to dividends or upon liquidation to
elect directors, any director (including persons elected by directors to fill
vacancies in the Board of Directors) may be removed from office only with cause
by an affirmative vote of not less than a majority of the votes eligible to be
cast by stockholders at a duly constituted meeting of stockholders called
expressly for such purpose.

         6.       BY-LAWS. The Board of Directors is expressly authorized and 
empowered to make, alter and repeal the by-laws of the Corporation, subject to
the power of the stockholders to alter or repeal the by-laws made by the Board
of Directors. Such action by the Board of Directors shall require the
affirmative vote of a majority of the directors then in office at any regular or
special meeting of the Board of Directors. Such action by the stockholders shall
require the affirmative vote of the holders of a majority of the shares of the
Corporation entitled to vote generally in an election of directors, voting
together as a single class, as well as such additional vote of the preferred
stock as may be required by the provisions of any series thereof.

         NINTH:   The personal liability of the directors and officers of the
Corporation for monetary damages shall be eliminated to the fullest extent
permitted by the General Corporation Law of the Commonwealth of Puerto Rico as
it exists on the effective date of this Certificate of

                                       5


Incorporation or as such law may be thereafter in effect. No amendment,
modification or repeal of this Article NINTH shall adversely affect the rights
provided hereby with respect to any claim, issue or matter in any proceeding
that is based in any respect on any alleged action or failure to act prior to
such amendment, modification or repeal.

         TENTH:   The affirmative vote of the holders of not less than seventy-
five percent (75%) of the total number of outstanding shares of the Corporation
shall be required to amend this Article TENTH to the extent that such amendment
is not approved by eighty percent (80%) of the Corporation's Board of Directors
then in office; to approve any Business Combination for which stockholder
approval is required by applicable law to the extent that such Business
Combination is not approved by eighty percent (80%) of the Corporation's Board
of Directors then in office; or to approve the voluntary dissolution of the
Corporation to the extent that such dissolution is not approved by eighty
percent (80%) of the Corporation's Board of Directors then in office,
notwithstanding that applicable law would otherwise permit any of the above with
the approval of fewer shares or without the approval of any shares.

         For purposes of this Article TENTH, the term "Business Combination"
shall mean:

         (a)      a merger, reorganization, or consolidation in which the 
Corporation is a constituent corporation; or

         (b)      the sale, lease, or hypothecation of substantially all the

Executive Officer, and as Secretary, respectively, of Oriental Financial Group
Inc. (the "Corporation"), a Puerto Rico corporation, HEREBY CERTIFY that,
pursuant to the authority conferred upon the Board of Directors by the
Corporation's Certificate of Incorporation, as amended, and resolutions adopted

vested in the Board of Directors of the Corporation and delegated to the
Preferred Stock Pricing Committee in accordance with the provisions of the
Corporation's Certificate of Incorporation, as amended, a series of Preferred
Stock of the Corporation be and it hereby is created.

<PAGE>   2

         FURTHER RESOLVED, that the designation and amount of such series and
the voting powers, 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 are as follows:

A.       DESIGNATION AND AMOUNT

         The shares of such series of Preferred Stock shall be designated as the
"__% Noncumulative 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 (the "Holders")
will be entitled to receive, when, as and if declared by the Board of Directors,
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.

         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 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 fifteenth day of the month containing 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.
<PAGE>   3

         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 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 Corporation 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 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 

<PAGE>   4


                                      -4-


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 full dividend on
the Series A Preferred Stock for the then-current dividend period (which shall
not include any accumulation in respect of unpaid dividends for prior dividend
periods) and full dividends, including required or permitted accumulations, if
any, on such other classes of equally ranked 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

         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
Section D 8 below, upon not less than thirty nor more than sixty days' notice by

                  2006 and thereafter                         $25.00
</TABLE>

         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 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 

<PAGE>   6


                                      -6-


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 any 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.

         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 

<PAGE>   7


                                      -7-

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 Corporation 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 $____ 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 of 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 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, 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 Corporation's
Certificate of Incorporation, as amended, 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, as amended, 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 

<PAGE>   9

                                      -9-

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 Restated 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.

G.       RANK

         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 


<PAGE>   10
                                      -10-


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

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

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 may determine.

records and other instruments, and such questions of law, as we have considered
necessary or appropriate for the purpose of this opinion.

         Upon the basis of such examination, we are of the opinion that when the

         RE:      NONCUMULATIVE MONTHLY INCOME PREFERRED STOCK, SERIES A

Ladies and Gentlemen:

         We have acted as counsel for Oriental Financial Group Inc. (the
"Company") in connection with a Registration Statement on Form S-3, filed with
the Securities and Exchange Commission on April 2, 1999 (the "Registration
Statement"), for the purpose of registering under the Securities Act of 1933, as
amended, up to 1,207,000 shares of Noncumulative Monthly Income Preferred Stock,
Series A, $1.00 par value per share, of the Company.

         We have examined the prospectus contained in the Registration Statement
(the "Prospectus") and have reviewed the discussion of certain United States 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

other documents and instruments and have examined such questions of law as we
have considered necessary or appropriate for the purpose of this opinion. In
addition, we have relied on certificates of officers of the Company as to
certain factual matters.

         The Tax Discussion represents our opinion regarding the material United
States and Puerto Rico tax consequences described therein.

         Our opinion is based upon the review of the Prospectus and of
applicable United States and Puerto Rico income tax statutes, regulations,
rulings and decisions, as now in full force and effect. A change in any of the
foregoing could require a change in our opinion. In addition, our opinion
pertains only to the accuracy of the statement of law contained in the Tax
Discussion. As to statements of fact, we are relying upon your representation
that such factual statements are true and accurate as of the date hereof.

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

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us under the heading "Taxation"
in the Prospectus contained in the Registration Statement. In giving the
foregoing consent, we do not thereby admit that we are in the category of
persons whose consent is required under Section 7 of the Act.


                                                     Very truly yours,
