ITEM 5.  OTHER EVENTS.

         On September 18, 1997, ML Bancorp, Inc. ("ML") and Sovereign Bancorp
("Sovereign") entered into an Agreement and Plan of Merger (the "Agreement")
which sets forth the terms and conditions under which ML will be merged with
and into Sovereign (the "Merger").  On the same date, Main Line Bank, a
wholly-owned subsidiary of ML, and Sovereign Bank, a wholly-owned subsidiary of
Sovereign, entered into an Agreement and Plan of Merger which sets forth the
terms and conditions under which Main Line Bank will be merged with and into
Sovereign Bank (the "Bank Merger") following consummation of the Merger.

         In accordance with the terms of the Agreement, each outstanding share
of ML common stock, par value $.01 per share (the "ML Common Stock"),
outstanding immediately prior to the effective date of the Merger (the
"Effective Date"), other than any shares held by holders who exercise
dissenters' rights under the Pennsylvania Business Corporation Law or as
otherwise provided in the Agreement, will be converted into the right to
receive a number of shares of Sovereign common stock, no par value per share
(the "Sovereign Common Stock"), based on an exchange ratio (the "Exchange
Ratio") which generally is determined based on the average of the closing high
bid and low asked prices of a share of Sovereign Common Stock for each of the
20 consecutive trading days ending on the trading day preceding the
Determination Date (the "Sovereign Market Value").  The Determination Date is
defined in the Agreement to be the earlier of (i) the date on which the Office
of Thrift Supervision ("OTS") approves the Merger and the Bank Merger (or the
later of such dates if the OTS approves such transactions on different dates)
and (ii) March 31, 1998.  Pursuant to the Agreement, (i) if the Sovereign
Market Value is greater than or equal to $13.80 and less than or equal to
$18.67, the Exchange Ratio shall be 1.67, (ii) if the Sovereign Market Value is
less than $13.80, the Exchange Ratio shall be equal to the quotient (rounded to
the nearest hundredth) determined by dividing $23.05 by the Sovereign Market
Value, provided that if the Sovereign Market Value is less than $12.18,
Sovereign shall have the right to elect to have the Exchange Ratio be equal to
the quotient determined by dividing $23.05 by $12.18, subject to ML's right to
terminate the Agreement under such circumstances and Sovereign's right to
eliminate such right of termination, as discussed below, and (iii) if the
Sovereign Market Value is greater than $18.67, the Exchange Ratio shall be
equal to the quotient (rounded to the nearest hundredth) determined by dividing
$31.18 by the Sovereign Market Value, provided that if on or before the
Effective Date there has been any public announcement of a proposed acquisition
or sale of all or substantially all of Sovereign's assets or a merger,
consolidation or similar transaction involving Sovereign in which Sovereign is
not the surviving entity or in which shareholders of Sovereign before such
transaction will not hold in the aggregate shares of the surviving or new
corporation to be outstanding immediately after the consummation thereof
entitled to cast at least a majority of the votes entitled to be cast generally
for the election of directors, the Exchange Ratio shall be 1.67.





                                       2

         Each holder of ML Common Stock who would otherwise be entitled to
receive a fraction of a share of Sovereign Common Stock (after taking into
account all of a shareholder's certificates) will receive cash, in lieu
thereof, without interest, based on the price of a share of the Sovereign
Common Stock on the Effective Date.

         The Agreement may be terminated by ML by giving notice to Sovereign at
any time during the ten-day period following the Determination Date if both (i)
the Sovereign Market Value shall be less than $12.18 and Sovereign shall have
made the election specified in the proviso clause in clause (ii) of the third
sentence in the second preceding paragraph and (ii) (x) the quotient obtained
by dividing the Sovereign Market Value by $16.24 shall be less than (y) the
quotient obtained by dividing the weighted average of the closing sales prices
of the common stocks of a specified index of thrift and bank holding companies
on the Determination Date by the weighted average of such closing prices on
September 17, 1997, and subtracting 0.10.  In the event that ML gives Sovereign
notice of its intent to terminate the Agreement pursuant to the conditions set
forth in the preceding sentence, Sovereign may determine, in its sole
discretion, to eliminate ML's right to terminate the Agreement by increasing
the Exchange Ratio to equal the quotient (rounded to the nearest hundredth)
determined by dividing $23.05 by the Sovereign Market Value.

         The Merger Agreement also provides that each option to purchase shares
of ML Common Stock under ML's stock option plans which is outstanding on the
Effective Date, whether or not exercisable, shall be converted into and become
a right to purchase shares of Sovereign Common Stock in accordance with the
terms of the ML stock option plan and ML option agreement by which it is
evidenced, except that from and after the Effective Date, (i) the number of
shares of Sovereign Common Stock subject to each ML option shall be equal to
the number of shares of ML Common Stock subject to such option prior to the
Effective Date multiplied by the Exchange Ratio (with fractional shares rounded
down to the nearest share) and (ii) the exercise price per share of Sovereign
Common Stock purchasable thereunder shall be that specified in the ML option
divided by the Exchange Ratio (rounded up to the nearest cent).

         The Merger is intended to constitute a reorganization under Section
368(a) of the Internal Revenue Code of 1986, as amended, and to be accounted
for as a pooling-of-interests under generally accepted accounting principles.
It is contemplated that ML will issue prior to the Effective Date a sufficient
number of shares of ML Common Stock so that the Merger will be accounted for in
the desired manner.

         Consummation of the Merger is subject to various conditions, including
(i) receipt of the requisite approval of the Agreement by the shareholders of
each of ML and Sovereign, (ii) receipt of requisite regulatory approvals from
the OTS and any other applicable regulatory authority, (iii) receipt of
opinions from the parties' respective legal counsel as to the tax treatment of
certain aspects of the Merger, (iv) receipt of letters from the parties'
respective independent public accountants to the effect that the Merger shall
be accounted for as a pooling-of-interests and (v) satisfaction of certain
other conditions.

         Upon consummation of the Bank Merger, Dennis S. Marlo, President and
Chief Executive Officer of ML and Main Line Bank, will be elected as President
of the Pennsylvania Division of Sovereign Bank, which shall consist of
Sovereign Bank's Pennsylvania and Delaware branch network.

         In connection with the Agreement, the directors and executive officers
of ML entered into a letter agreement with Sovereign pursuant to which each
such person agreed in his personal capacity to vote the shares of ML Common
Stock beneficially owned by him in favor of the Agreement at the meeting of ML
shareholders called for the purpose of considering the same and to not transfer
such shares of ML Common Stock or shares of Sovereign Common Stock acquired
upon consummation of the Merger or otherwise during specified periods, and the
directors and executive officers of Sovereign entered into a similar letter
agreement with ML with respect to the shares of Sovereign Common Stock
beneficially owned by them.

         In connection with the Agreement, ML and Sovereign entered into a
Stock Option Agreement, dated as of September 18, 1997 (the "Option
Agreement"), pursuant to which ML granted to Sovereign an option to purchase,
under certain circumstances, up to 2,361,245 shares of ML Common Stock
(representing 19.9% of the currently outstanding shares of ML Common Stock) at
a price of $21.875 per share (the "Option").  Under certain circumstances, ML
may be required to repurchase the Option or the shares acquired pursuant to the
exercise thereof.  The Option Agreement was entered into by ML as a condition
to Sovereign's willingness to enter into the Agreement.

         Common Stock shall be converted into the right to receive Sovereign
         Common Stock in accordance with Section 1.02(e)(ii) of this Agreement.

         may be exercised solely for shares of Sovereign Common Stock and
         Sovereign Stock Purchase Rights, (iii) the number of shares of

         Exchange Ratio, provided that any fractional shares of Sovereign

         price under each such ML Option by the Applicable Exchange Ratio,

         conditions, including without limitation the duration thereof, subject
         to the adjustments required by Section 1.02(f)(i) hereof after giving

         holder's shares of ML Common Stock have been converted pursuant to the
         Merger, together with a check for cash in lieu of any fractional share

         certificate for shares of Sovereign Common Stock issued in exchange
         for certificates for ML Common Stock pursuant to Section 1.02(g)(i)
         hereof will be dated the Effective Date and be entitled to dividends
         and all other rights and privileges pertaining to such shares of stock
         from and after the Effective Date.  Until surrendered, each
         certificate theretofore evidencing shares of ML Common Stock will,

         payment of dividends or of any other distribution on the shares of
         Sovereign Common Stock, Sovereign will pay cash in an amount equal to
         dividends theretofore payable on such Sovereign Common Stock and pay
         or deliver any other distribution to which holders of shares of
         Sovereign Common Stock have theretofore become entitled.  Upon
         surrender of certificates for shares of ML Common Stock in exchange
         for certificates for Sovereign Common Stock, Sovereign also shall pay
         any dividends to which such holder of ML Common Stock may be entitled
         as a result of the declaration of a dividend on the ML Common Stock by
         ML in accordance with the terms of this Agreement with a record date
         prior to the Effective Date and a payment date after the Effective
         Date.  No interest will accrue or be payable in respect of dividends
         or cash otherwise payable under this Section 1.02(g) upon surrender of
         certificates for shares of ML Common Stock.  Notwithstanding the
         foregoing, no party hereto will be liable to any holder of ML Common
         Stock for any amount paid in good faith to a public official or agency
         pursuant to any applicable abandoned property, escheat or similar law.
         Until such time as certificates for shares of

         thereof or be accompanied by a power of attorney to transfer such
         shares endorsed in blank by such holder.  If more than one certificate

         shareholder account, the number of whole shares of Sovereign Common
         Stock for which certificates will be issued pursuant to this Section
         1.02(g) will be computed on the basis of the aggregate number of
         shares represented by the certificates so surrendered.  If shares of
         Sovereign Common Stock or payments of cash are to be issued or made to
         a person other than the one in whose name the surrendered certificate
         is registered, the certificate so surrendered must be properly

         such issuance or payment to a person other than the registered holder
         of the certificate for shares of ML Common Stock which are
         surrendered.  As promptly as practicable after the Effective Date,
         Sovereign shall send or cause to be sent to each shareholder of record
         of ML Common Stock transmittal materials for use in exchanging
         certificates representing ML Common Stock for certificates
         representing Sovereign Common Stock into which the former have been
         converted in the Merger.  Certificates representing shares of
         Sovereign Common Stock and checks for cash in lieu of fractional
         shares shall be mailed to former shareholders of ML as soon as
         reasonably possible but in no event later than fifteen (15) business
         days following the receipt of certificates representing former shares
         of ML Common Stock duly endorsed or accompanied by the materials
         referenced herein and delivered by certified mail, return receipt
         requested (but in no event earlier than the second business day
         following the Effective Date).

                                  (iv)   Closing of Stock Transfer Books;
         Cancellation of ML Certificates.  Upon the Effective Date, the
         stock transfer books for ML Common Stock will be closed and no
         further transfers of shares of ML Common Stock will thereafter
         be made or recognized.  All certificates for shares of ML
         Common Stock surrendered pursuant to this Section 1.02(g) will
         be cancelled by Sovereign.

                          (h)     Anti-Dilution Provisions.  If, Sovereign has,
at any time after the date hereof and before the Effective Date, (A) issued a
dividend in shares of Sovereign Common Stock, (B) combined the outstanding
shares of Sovereign Common Stock into a smaller number of shares, (C)
subdivided the outstanding shares of Sovereign Common Stock, or (D)
reclassified the shares of Sovereign Common Stock, then the number of shares of
Sovereign Common Stock to be delivered to ML shareholders who are entitled to
receive shares of Sovereign Common Stock in exchange for shares of ML Common
Stock shall be adjusted so that each ML shareholder shall be entitled to
receive such number of shares of Sovereign Common Stock as such shareholder
would have been entitled to receive if the Effective Date had occurred prior to
the happening of such event.  (By way of illustration, if Sovereign shall
declare a stock dividend of 7% payable with respect to a record date on or
prior to the Effective Date and the conditions set forth above are satisfied,
the Applicable Exchange Ratio shall be adjusted upward by 7%).

                 Section 1.03  The Bank Merger.  Sovereign and ML shall use
their reasonable best efforts to cause Main Line Bank to merge with and into
Sovereign Bank, with Sovereign Bank surviving such merger, on or as soon as

shall cause Sovereign Bank, and ML shall cause Main Line Bank, to execute and
deliver the Bank Plan of Merger attached hereto as Exhibit 3.

Schedule, ML and the ML Subsidiaries have, or will have as to property acquired
after the date hereof, good and, as to real property, marketable title to all
assets and properties owned by ML or any ML Subsidiary in the conduct of their
businesses, whether such assets and properties are real or personal, tangible
or intangible, including assets and property reflected in the balance sheets
contained in the ML Regulatory Reports and in the ML Financials or acquired
subsequent thereto (except to the extent that such assets and properties have
been disposed of for fair value, in the ordinary course of business, since the
date of such balance sheets), subject to no encumbrances, liens, mortgages,
security interests or pledges, except (i) those items which secure repurchase
agreements and liabilities for borrowed money from a Federal Home Loan Bank,
(ii) statutory liens for amounts not yet delinquent or which are being
contested in good faith and (iii) items permitted under Article IV.  ML and the
ML Subsidiaries, as lessee, have the right under valid and subsisting leases of
real and personal properties used by ML and its Subsidiaries in the conduct of
their businesses to occupy or use all such properties as presently occupied and
used by each of them.  Except as disclosed in the ML Disclosure Schedule, such
existing leases and commitments to lease constitute or will constitute
operating leases for both tax and financial accounting purposes and the lease
expense and minimum rental commitments with respect to such leases and lease
commitments are as disclosed in the notes to the ML Financials.

                          (b)     With respect to all agreements pursuant to
which ML or any ML Subsidiary has purchased securities subject to an agreement
to resell, if any, ML or such ML Subsidiary, as the case may be, has a valid,
perfected first lien or security interest in the securities or other collateral
securing the repurchase agreement, and the value of such collateral equals or
exceeds the amount of the debt secured thereby.

                          (c)     ML and the ML Subsidiaries currently maintain
insurance considered by ML to be reasonable for their respective operations and
similar in scope and coverage to that maintained by other businesses similarly
engaged.  Neither ML nor any ML Subsidiary has received notice from any
insurance carrier that (i) such insurance will be cancelled or that coverage
thereunder will be reduced or eliminated, or (ii) premium costs with respect to
such policies of insurance will be substantially increased.





                                       21
<PAGE>   27
There are presently no material claims pending under such policies of insurance
and no notices have been given by ML or Main Line Bank under such policies.
All such insurance is valid and enforceable and in full force and effect, and
within the last three years ML has received each type of insurance coverage for
which it has applied and during such periods has not been denied
indemnification for any material claims submitted under any of its insurance
policies.

                 Section 2.10  Legal Proceedings.  Except as disclosed in the
ML Disclosure Schedule, neither ML nor any ML Subsidiary is a party to any, and
there are no pending or, to the best of ML's knowledge, threatened legal,
administrative, arbitration or other proceedings, claims (whether asserted or
unasserted), actions or governmental investigations or inquiries of any nature
(i) against ML or any ML Subsidiary, (ii) to which ML or any ML Subsidiary's
assets are or may be subject, (iii) challenging the validity or propriety of
any of the transactions contemplated by this Agreement, or (iv) which could
adversely affect the ability of ML to perform under this Agreement, except for
any proceedings, claims, actions, investigations or inquiries referred to in
clauses (i) or (ii) which, if adversely determined, individually or in the
aggregate, could not be reasonably expected to have a Material Adverse Effect
on ML.

                 Section 2.11  Compliance With Applicable Law.

                          (a)     ML and ML Subsidiaries hold all licenses,
franchises, permits and authorizations necessary for the lawful conduct of
their businesses under, and have complied in all material respects with,
applicable laws, statutes, orders, rules or regulations of any federal, state
or local governmental authority relating to them, other than where such failure
to hold or such noncompliance will neither result in a limitation in any
material respect on the conduct of their businesses nor otherwise have a
Material Adverse Effect on ML.

                          (b)     Except as disclosed in the ML Disclosure
Schedule, neither ML nor any ML Subsidiary has received any notification or
communication from any Regulatory Authority (i) asserting that ML or any ML
Subsidiary is not in compliance with any of the statutes, regulations or
ordinances which such Regulatory Authority enforces; (ii) threatening to revoke
any license, franchise, permit or governmental authorization which is material
to ML or any ML Subsidiary; (iii) requiring or threatening to require ML or any
ML Subsidiary, or indicating that ML or any ML Subsidiary may be required, to
enter into a cease and desist order, agreement or memorandum of understanding
or any other agreement restricting or limiting, or purporting to restrict or
limit, in any manner the operations of ML or any ML Subsidiary, including
without limitation any restriction on the payment of dividends; or (iv)
directing, restricting or limiting, or purporting to direct,





                                       22
<PAGE>   28
restrict or limit, in any manner the operations of ML or any ML Subsidiary,
including without limitation any restriction on the payment of dividends (any
such notice, communication, memorandum, agreement or order described in this
sentence is hereinafter referred to as a "Regulatory Agreement").  Neither ML
nor any ML Subsidiary has consented to or entered into any Regulatory
Agreement, except as heretofore disclosed to Sovereign.

                 Section 2.12  ERISA.  ML has previously delivered to Sovereign
true and complete copies of all employee pension benefit plans within the
meaning of ERISA Section 3(2), profit sharing plans, stock purchase plans,
deferred compensation and supplemental income plans, supplemental executive
retirement plans, employment agreements, annual or long term incentive plans,
severance plans, policies and agreements, group insurance plans, and all other
employee welfare benefit plans within the meaning of ERISA Section 3(1)
(including vacation pay, sick leave, short-term disability, long-term
disability, and medical plans) and all other employee benefit plans, policies,
agreements and arrangements, all of which are set forth in the ML Disclosure
Schedule, maintained or contributed to for the benefit of the employees or
former employees (including retired employees) and any beneficiaries thereof or
directors or former directors of ML or any ML Subsidiary, together with (i) the
most recent actuarial (if any) and financial reports relating to those plans
which constitute "qualified plans" under IRC Section 401(a), (ii) the most
recent annual reports relating to such plans filed by them, respectively, with
any government agency, and (iii) all rulings and determination letters which
pertain to any such plans.  Neither ML, any ML Subsidiary nor any pension plan
maintained by ML or any ML Subsidiary, has incurred, directly or indirectly,
within the past six (6) years any liability under Title IV of ERISA (including
to the Pension Benefit Guaranty Corporation) or to the IRS with respect to any
pension plan qualified under IRC Section 401(a) which liability has resulted in
or will result in a Material Adverse Effect with respect to ML, except
liabilities to the Pension Benefit Guaranty Corporation pursuant to ERISA
Section 4007, all of which have been fully paid, nor has any reportable event
under ERISA Section 4043 occurred with respect to any such pension plan.  With
respect to each of such plans that is subject to Title IV of ERISA, the present
value of the accrued benefits under such plan, based upon the actuarial
assumptions used for funding purposes in the plan's most recent actuarial
report did not, as of its latest valuation date, exceed the then current value
of the assets of such plan allocable to such accrued benefits.  Neither ML nor
any ML Subsidiary has incurred or is subject to any liability under ERISA
Section 4201 for a complete or partial withdrawal from a multi-employer plan.
All "employee benefit plans," as defined in ERISA Section 3(3), comply and
within the past six (6) years have complied in all material respects with (i)
relevant provisions of ERISA and (ii) in the case of plans intended to qualify
for favorable income tax treatment, provisions of the IRC relevant to such
treatment.  No prohibited transaction





                                       23
<PAGE>   29
(which shall mean any transaction prohibited by ERISA Section 406 and not
exempt under ERISA Section 408 or any transaction prohibited under IRC Section
4975) has occurred within the past six (6) years with respect to any employee
benefit plan maintained by ML or any ML Subsidiary which would result in the
imposition, directly or indirectly, of an excise tax under IRC Section 4975 or
other penalty under ERISA or the IRC, which, individually or in the aggregate,
has resulted in or will result in a Material Adverse Effect with respect to ML.
ML and the ML Subsidiaries provide continuation coverage under group health
plans for separating employees and "qualified beneficiaries" in accordance with
the provisions of IRC Section 4980B(f).  Such group health plans are in
compliance with Section 1862(b)(1) of the Social Security Act.  Neither ML nor
any ML Subsidiary is aware of any existing or contemplated audit of any of its
employee benefit plans by the Internal Revenue Service or U.S. Department of
Labor.

                 Section 2.13  Brokers, Finders and Financial Advisors.  Except
for ML's engagement of Sandler O'Neill & Partners L.P. in connection with the
transactions contemplated by this Agreement, neither ML nor any ML Subsidiary,
nor any of their respective officers, directors, employees or agents, has
employed any broker, finder or financial advisor in connection with the
transactions contemplated by this Agreement or in connection with any
transaction other than the Merger, or, except for its commitments disclosed in
the ML Disclosure Schedule, incurred any liability or commitment for any fees
or commissions to any such person in connection with the transactions
contemplated by this Agreement or in connection with any transaction other than
the Merger, which has not been reflected in the ML Financials.  The ML
Disclosure Schedule shall contain as an exhibit the engagement letter between
ML and Sandler O'Neill & Partners L.P.

                 Section 2.14  Environmental Matters.  To the knowledge of ML,
neither ML nor any ML Subsidiary, nor any properties owned or operated by ML or
any ML Subsidiary has been or is in violation of or liable under any
Environmental Law which violation or liability, individually or in the
aggregate, resulted in, or will result, in a Material Adverse Effect with
respect to ML.  There are no actions, suits or proceedings, or demands, claims,
notices or investigations (including without limitation notices, demand letters
or requests for information from any environmental agency) instituted or
pending, or to the knowledge of ML, threatened, relating to the liability of
any property owned or operated by ML or any ML Subsidiary under any
Environmental Law.

                 Section 2.15  Allowance for Loan Losses.  The allowance for
loan losses reflected, and to be reflected, in the ML Regulatory Reports, and
shown, and to be shown, on the balance sheets contained in the ML Financials
have been, and will be, established in accordance with the requirements of GAAP
and all applicable regulatory criteria.

<PAGE>   30
                 Section 2.16  Information to be Supplied.  The information to
be supplied by ML and Main Line Bank for inclusion in the Registration
Statement (including the Prospectus/Proxy Statement) will not, at the time the
Registration Statement is declared effective pursuant to the Securities Act and
as of the date the Prospectus/Proxy Statement is mailed to shareholders of
Sovereign and ML and up to and including the date(s) of the meetings of
shareholders of Sovereign and ML to which such Prospectus/Proxy Statement
relates, contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements therein not misleading.
The information supplied, or to be supplied, by ML for inclusion in the
Applications will, at the time such documents are filed with any Regulatory
Authority and up to and including the date(s) of the obtainment of any required
regulatory approvals or consents, be accurate in all material aspects.

                 Section 2.17  Securities Documents.  ML has delivered to
Sovereign copies of its (i) annual reports on SEC Form 10-K for the years ended
March 31, 1997, 1995 and 1994, (ii) a quarterly report on SEC Form 10-Q for the
quarter ended June 30, 1997, and (iii) proxy materials used in connection with
its meetings of shareholders held in 1997, 1996 and 1995.  Such reports and
such proxy materials complied, at the time filed with the SEC, in all material
respects, with the Exchange Act and all applicable rules and regulations of the
SEC.

                 Section 2.18  Related Party Transactions.  Except as disclosed
(i) in the ML Disclosure Schedule, (ii) in the ML proxy statement dated June
13, 1997 or (iii) in the footnotes to the ML Financials, ML is not a party to
any transaction (including any loan or other credit accommodation but excluding
deposits in the ordinary course of business) with any Affiliate of ML (except
an ML Subsidiary); and all such transactions (a) were made in the ordinary
course of business, (b) were made on substantially the same terms, including
interest rates and collateral, as those prevailing at the time for comparable
transactions with other Persons, and (c) did not involve more than the normal
risk of collectability or present other unfavorable features.  Except as set
forth on the ML Disclosure Schedule, no loan or credit accommodation to any
Affiliate of ML is presently in default or, during the three year period prior
to the date of this Agreement, has been in default or has been restructured,
modified or extended.  Neither ML nor Main Line Bank has been notified that
principal and interest with respect to any such loan or other credit
accommodation will not be paid when due or that the loan grade classification
accorded such loan or credit accommodation by Main Line Bank is inappropriate.

                 Section 2.19  Loans.  Each loan reflected as an asset in the
ML Financial Statements (i) is evidenced by notes, agreements or other
evidences of indebtedness which are true, genuine and





                                       25
<PAGE>   31
correct (ii) to the extent secured, has been secured by valid liens and
security interests which have been perfected, and (ii) is the legal, valid and
binding obligation of the obligor named therein, enforceable in accordance with
its terms, subject to bankruptcy, insolvency, fraudulent conveyance and other
laws of general applicability relating to or affecting creditors' rights and to
general equity principles, in each case other than loans as to which the
failure to satisfy the foregoing standards would not have a Material Adverse
Effect on ML.

                 Section 2.20  Accounting for the Merger; Reorganization.  As
of the date hereof, ML does not have any reason to believe that the Merger will
fail to qualify (i) for pooling-of-interests accounting treatment under GAAP,
assuming compliance by ML and Sovereign with the requirements of Section 4.16
hereof, or (ii) as a reorganization under Section 368(a) of the IRC.

                 Section 2.21  Fairness Opinion.  ML has received a written
opinion from Sandler O'Neill & Partners L.P. to the effect that, as of the date
hereof, the consideration to be received by shareholders of ML pursuant to this
Agreement is fair, from a financial point of view, to such shareholders.

                 Section 2.22  Quality of Representations.  The representations
made by ML in this Agreement are true, correct and complete in all material
respects, and do not omit statements necessary to make them not misleading
under all facts and circumstances.

                  REPRESENTATIONS AND WARRANTIES OF SOVEREIGN

<PAGE>   32
a foreign corporation in any jurisdiction other than the Commonwealth of

duly organized and validly existing under the laws of the United States.

                                       28

agreement or other investment or obligation to which Sovereign or any Sovereign
Subsidiary is a party, or by which they or any of their respective properties
or assets may be bound or affected, except for such violations, conflicts,

fairly present, or will fairly present, the consolidated financial position,
results of operations and cash flows of Sovereign as of and for the periods
ending on the dates thereof, in accordance with GAAP applied on a consistent
basis, except as noted therein.

footnotes thereto which are not fully reflected or reserved against therein or
disclosed in a footnote thereto, except for liabilities, obligations or loss
contingencies which are not material in the aggregate and which are incurred in
the ordinary course of business, consistent with past practice, and except for
liabilities, obligations or loss contingencies which are within the subject
matter of a specific representation and warranty herein and subject, in the
case of any unaudited statements, to normal recurring audit adjustments and the

which (i) are not delinquent or (ii) are being contested in good faith.

                 Section 3.07  No Material Adverse Effect.  Sovereign has not
suffered any Material Adverse Effect since June 30, 1997.

                 Section 3.08  Ownership of Property; Insurance Coverage.

                          (a)     Sovereign and the Sovereign Subsidiaries have
good and, as to real property, marketable title to all assets and properties
owned by Sovereign or any of its Subsidiaries in the conduct of their
businesses, whether such assets and properties are real or personal, tangible
or intangible, including assets and property reflected in the balance sheets
contained in the Sovereign Regulatory Reports and in the Sovereign Financials
or acquired subsequent thereto (except to the extent that such assets and
properties have been disposed of for fair value, in the ordinary course of
business, since the date of such balance sheets), subject to no encumbrances,
liens, mortgages, security interests or pledges, except (i) those items that
secure liabilities for borrowed money and that are described in the Sovereign
Disclosure Schedule or permitted under Article IV hereof, and (ii) statutory
liens for amounts not yet delinquent or which are being contested in good
faith.  Sovereign and the Sovereign Subsidiaries, as lessee, have the right
under valid and subsisting leases of real and personal properties used by
Sovereign and its Subsidiaries in the conduct of their businesses to occupy and
use all such properties as presently occupied and used by each of them.

                          (b)     Sovereign and the Sovereign Subsidiaries
currently maintain insurance in amounts considered by Sovereign to be
reasonable for their respective operations, and such insurance is similar in
scope and coverage to that maintained by other businesses similarly engaged.
Neither Sovereign nor any Sovereign Subsidiary has received notice from any
insurance carrier that (i) such insurance will be cancelled or that coverage
thereunder will be reduced or eliminated or (ii) premium costs with respect to
such insurance will be substantially increased.

                 Section 3.09  Legal Proceedings.  Neither Sovereign nor any
Sovereign Subsidiary is a party to any, and there are no pending or, to the
best of Sovereign's knowledge, threatened legal, administrative, arbitration or
other proceedings, claims, actions or governmental investigations or inquiries
of any nature (i) against Sovereign or any Sovereign Subsidiary, (ii) to which
Sovereign's or any Sovereign Subsidiary's assets are or may be subject, (iii)
challenging the validity or propriety of any of the transactions contemplated
by this Agreement, or (iv) which could adversely affect the ability of
Sovereign to perform under this Agreement, except for any proceedings, claims,
actions, investigations or inquiries referred to in clauses (i) or (ii)





                                       31

                          (a)     Sovereign and the Sovereign Subsidiaries hold
all licenses, franchises, permits and authorizations necessary for the lawful
conduct of their businesses under, and have complied in all material respects
with, applicable laws, statutes, orders, rules or regulations of any federal,
state or local governmental authority relating to them, other than where such
failure to hold or such noncompliance will neither result in a limitation in
any material respect on the conduct of their businesses nor otherwise have a
Material Adverse Effect on Sovereign.

                          (b)     Neither Sovereign nor any Sovereign
Subsidiary has received any notification or communication from any Regulatory
Authority (i) asserting that Sovereign or any Sovereign Subsidiary is not in
compliance with any of the statutes, regulations or ordinances which such
Regulatory Authority enforces; (ii) threatening to revoke any license,
franchise, permit or governmental authorization which is material to Sovereign
or any Sovereign Subsidiary; (iii) requiring or threatening to require
Sovereign or any Sovereign Subsidiary, or indicating that Sovereign or any
Sovereign Subsidiary may be required, to enter into a cease and desist order,
agreement or memorandum of understanding or any other agreement restricting or
limiting, or purporting to restrict or limit, in any manner the operations of
Sovereign or any Sovereign Subsidiary, including without limitation any
restriction on the payment of dividends; or (iv) directing, restricting or
limiting, or purporting to direct, restrict or limit, in any manner the
operations of Sovereign or any Sovereign Subsidiary, including without
limitation any restriction on the payment of dividends (any such notice,
communication, memorandum, agreement or order described in this sentence is
hereinafter referred to as a "Regulatory Agreement").  Neither Sovereign nor
any Sovereign Subsidiary has consented to or entered into any Regulatory
Agreement, except as heretofore disclosed to ML.

                 Section 3.11  Information to be Supplied.  The information to
be supplied by Sovereign for inclusion in the Registration Statement (including
the Prospectus/Proxy Statement) will not, at the time the Registration
Statement is declared effective pursuant to the Securities Act and as of the
date the Prospectus/Proxy Statement is mailed to shareholders of Sovereign and
ML and up to and including the date(s) of the meetings of shareholders of
Sovereign and ML to which such Prospectus/Proxy Statement relates, contain any
untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements therein not misleading.  The
information supplied, or to be supplied, by Sovereign for inclusion in the
Applications will, at the time such documents are filed with any Regulatory
Authority





                                       32
<PAGE>   38
and up to and including the date(s) of the obtainment of any required
regulatory approvals or consents, be accurate in all material aspects.

                 Section 3.12  ERISA.  Sovereign has previously made available
to ML true and complete copies of the employee pension benefit plans within the
meaning of ERISA Section 3(2), profit sharing plans, stock purchase plans,
deferred compensation and supplemental income plans, supplemental executive
retirement plans, annual incentive plans, group insurance plans, and all other
employee welfare benefit plans within the meaning of ERISA Section 3(1)
(including vacation pay, sick leave, short-term disability, long-term
disability, and medical plans), and all other employee benefit plans, policies,
agreements and arrangements, all of which are set forth on the Sovereign
Disclosure Schedule, maintained or contributed to for the benefit of the
employees or former employees (including retired employees) and any
beneficiaries thereof or directors or former directors of Sovereign or any
Sovereign Subsidiary, together with (i) the most recent actuarial (if any) and
financial reports relating to those plans which constitute "qualified plans"
under IRC Section 401(a), (ii) the most recent annual reports relating to such
plans filed by them, respectively, with any government agency, and (iii) all
rulings and determination letters which pertain to any such plans.  Neither
Sovereign nor any Sovereign Subsidiary, and no pension plan maintained by
Sovereign or any Sovereign Subsidiary, has incurred, directly or indirectly,
within the past six (6) years any liability under Title IV of ERISA (including
to the Pension Benefit Guaranty Corporation) or to the IRS with respect to any
pension plan qualified under IRC Section 401(a) which liability has resulted in
or will result in a Material Adverse Effect with respect to Sovereign, except
liabilities to the Pension Benefit Guaranty Corporation pursuant to ERISA
Section 4007, all of which have been fully paid, nor has any reportable event
under ERISA Section 4043 occurred with respect to any such pension plan.  With
respect to each of such plans that is subject to Title IV of ERISA, the present
value of the accrued benefits under such plan, based upon the actuarial
assumptions used for funding purposes in the plan's most recent actuarial
report did not, as of its latest valuation date, exceed the then current value
of the assets of such plan allocable to such accrued benefits.  Neither
Sovereign nor any Sovereign Subsidiary has incurred or is subject to any
liability under ERISA Section 4201 for a complete or partial withdrawal from a
multi-employer plan.  All "employee benefit plans," as defined in ERISA Section
3(3), comply and within the past six (6) years have complied in all material
respects with (i) relevant provisions of ERISA, and (ii) in the case of plans
intended to qualify for favorable income tax treatment, provisions of the IRC
relevant to such treatment.  No prohibited transaction (which shall mean any
transaction prohibited by ERISA Section 406 and not exempt under ERISA Section
408 or any transaction prohibited under IRC Section 4975) has occurred within
the past six (6) years with respect to any employee benefit plan maintained by





                                       33
<PAGE>   39
Sovereign or any Sovereign Subsidiary that would result in the imposition,
directly or indirectly, of an excise tax under IRC Section 4975 or other
penalty under ERISA or the IRC, which individually or in the aggregate, has
resulted in or will result in a Material Adverse Effect with respect to
Sovereign.  Sovereign and the Sovereign Subsidiaries provide continuation
coverage under group health plans for separating employees and "qualified
beneficiaries" in accordance with the provisions of IRC Section 4980B(f).  Such
group health plans are in compliance with Section 1862(b)(1) of the Social
Security Act.

                 Section 3.13  Securities Documents.  Sovereign has delivered
to ML copies of its (i) annual reports on SEC Form 10-K for the years ended
December 31, 1996, 1995 and 1994, (ii) quarterly reports on SEC Form 10-Q for
the quarters ended March 31, 1997 and June 30, 1997, (iii)  current reports on
SEC Form 8-K dated February 5, 1997, February 6, 1997, February 13, 1997, March
18, 1997 and June 17, 1997 and (iv) proxy statement dated March 19, 1997 used
in connection with its annual meeting of shareholders held in April 1997.  Such
reports and such proxy materials complied, at the time filed with the SEC, in
all material respects, with the Exchange Act and the applicable rules and
regulations of the SEC.

                 Section 3.14  Environmental Matters.  To the knowledge of
Sovereign, neither Sovereign nor any Sovereign Subsidiary, nor any properties
owned or operated by Sovereign or any Sovereign Subsidiary has been or is in
violation of or liable under any Environmental Law which violation or
liability, individually or in the aggregate, resulted in or will result in a
Material Adverse Effect with respect to Sovereign.  There are no actions, suits
or proceedings, or demands, claims, notices or investigations (including
without limitation notices, demand letters or requests for information from any
environmental agency) instituted or pending, or to the knowledge of Sovereign,
threatened, relating to the liability of any property owned or operated by
Sovereign or any Sovereign Subsidiary under any Environmental Law.

                 Section 3.15  Allowance for Loan Losses.  The allowance for
loan losses reflected, and to be reflected, in the Sovereign Regulatory
Reports, and shown, and to be shown, on the balance sheets contained in the
Sovereign Financials have been, and will be, established in accordance with the
requirements of GAAP and all applicable regulatory criteria.

                 Section 3.16  Brokers and Finders.  In connection with the
transactions contemplated by this Agreement, neither Sovereign nor any
Sovereign Subsidiary, nor any of their respective officers, directors,
employees or agents, has employed any broker, finder or financial advisor, or
incurred any liability for any fees or commissions to any such person, in
connection with the transactions contemplated by this Agreement.

                 Section 3.17  Loans.  Each loan reflected as an asset in the
Sovereign Financial Statements (i) is evidenced by notes, agreements or other
evidences of indebtedness which are true, genuine and correct (ii) to the
extent secured, has been secured by valid liens and security interests which
have been perfected, and (ii) is the legal, valid and binding obligation of the
obligor named therein, enforceable in accordance with its terms, subject to
bankruptcy, insolvency, fraudulent conveyance and other laws of general
applicability relating to or affecting creditors' rights and to general equity
principles, in each case other than loans as to which the failure to satisfy
the foregoing standards would not have a Material Adverse Effect on Sovereign.

                 Section 3.18  Accounting for the Merger; Reorganization.  As
of the date hereof, Sovereign does not have any reason to believe that the
Merger will fail to qualify (i) for pooling-of-interests treatment under GAAP,
assuming compliance by ML and Sovereign with the requirements of Section 4.16
hereof, or (ii) as a reorganization under Section 368(a) of the IRC.

                 Section 3.19  Quality of Representations.  The representations
made by Sovereign in this Agreement are true, correct and complete in all
material respects and do not omit statements necessary to make the
representations not misleading under the circumstances.

                                   ARTICLE IV
                            COVENANTS OF THE PARTIES

                 Section 4.01  Conduct of ML's Business.

                          (a)     From the date of this Agreement to the
Closing Date, ML and each ML Subsidiary will conduct its business and engage in
transactions, including extensions of credit, only in the ordinary course and
consistent with past practice and policies, except as otherwise required by
this Agreement or with the written consent of Sovereign.  ML will use its
reasonable good faith efforts, and will cause Main Line Bank to use its
reasonable good faith efforts, to (i) preserve its business organizations
intact, (ii) maintain good relationships with employees, and (iii) preserve for
itself the good will of customers of ML and ML Subsidiaries and others with
whom business relationships exist.  From the date hereof to the Closing Date,
except as otherwise consented to or approved by Sovereign in writing or as
permitted or required by this Agreement, ML will not, and ML will not permit
any ML Subsidiary to:

                                  (i)  amend or change any provision of its
         certificate or articles of incorporation, charter, or bylaws;

                                  (ii)  except as required by Section 4.16,
         change the number of authorized or issued shares of its





                                       35
<PAGE>   41
         capital stock or issue or grant any option, warrant, call, commitment,
         subscription, Right or agreement of any character relating to its
         authorized or issued capital stock or any securities convertible into
         shares of such stock, or split, combine or reclassify any shares of
         capital stock, or declare, set aside or pay any dividend or other
         distribution in respect of capital stock, or redeem or otherwise
         acquire any shares of capital stock, except that (A) ML may issue up
         to an aggregate of 1,442,200 shares of ML Common Stock upon the valid
         exercise of ML Options, (B) ML may issue shares of ML Common Stock and
         options to purchase shares of ML Common Stock in October 1997 to the
         extent required by the ML Recognition and Retention Plan and the ML
         1994 Stock Option Plan, as set forth in Section 2.02 hereof, (C) ML
         may issue shares of ML Common Stock pursuant to the Sovereign Option,
         (D) ML may pay one regular quarterly cash dividend in the calendar
         quarter ended December 31, 1997, not to exceed $.10 per share of ML
         Common Stock outstanding; and thereafter, ML may pay a quarterly cash
         dividend not to exceed $.033 per share of ML Common Stock outstanding,
         provided that if the shareholders of each of Sovereign and ML have not
         approved the Merger prior to the end of any such calendar quarter
         occurring after December 31, 1997, ML may declare and pay an
         additional dividend equal to $.067 per share of ML Common Stock
         outstanding for such quarter and (E) ML Capital Trust I may make
         distributions on its 9.875% Capital Securities in accordance with
         their terms.  As promptly as practicable following the date of this
         Agreement, the Board of Directors of ML shall cause its regular
         quarterly dividend record dates and payment dates to be the same as
         Sovereign's regular quarterly dividend record dates and payment dates
         for Sovereign Common Stock, and ML shall not change its regular
         dividend payment dates and record dates without prior written consent
         of Sovereign.  Nothing contained in this Section 4.01(ii) or in any
         other Section of this Agreement shall be construed to permit ML
         shareholders to receive two dividends either from ML or from ML and
         Sovereign in any quarter or to deny or prohibit them from receiving
         one dividend from ML or Sovereign in any quarter.  Nothing contained
         herein shall be deemed to affect the ability of an ML Subsidiary to
         pay dividends on its capital stock to ML subject to applicable
         regulatory restrictions.

                                  (iii)  grant any severance or termination pay
         (other than pursuant to written policies or written agreements of ML
         or ML Subsidiaries in effect on the date hereof and provided to
         Sovereign prior to the date hereof) to, or enter into any new or amend
         any existing employment agreement with, or increase the compensation
         of, any employee, officer or director of ML or any ML Subsidiary,
         except for routine periodic increases, individually and in the
         aggregate, in accordance with past practice;

                                  (iv)  merge or consolidate ML or any ML
         Subsidiary with any other corporation; sell or lease all or any
         substantial portion of the assets or business of ML or any ML
         Subsidiary; make any acquisition of all or any substantial portion of
         the business or assets of any other person, firm, association,
         corporation or business organization other than in connection with the
         collection of any loan or credit arrangement between any ML Subsidiary
         and any other person; enter into a purchase and assumption transaction
         with respect to deposits and liabilities; permit the revocation or
         surrender by any ML Subsidiary of its certificate of authority to
         maintain, or file an application for the relocation of, any existing
         branch office, or file an application for a certificate of authority
         to establish a new branch office;

                                  (v)  sell or otherwise dispose of the capital
         stock of Main Line Bank or sell or otherwise dispose of any asset of
         ML or of any ML Subsidiary other than in the ordinary course of
         business consistent with past practice; subject any asset of ML or of
         any ML Subsidiary to a lien, pledge, security interest or other
         encumbrance (other than in connection with deposits, repurchase
         agreements, bankers acceptances, "treasury tax and loan" accounts
         established in the ordinary course of business and transactions in
         "federal funds" and the satisfaction of legal requirements in the
         exercise of trust powers) other than in the ordinary course of
         business consistent with past practice; incur any indebtedness for
         borrowed money (or guarantee any indebtedness for borrowed money),
         except in the ordinary course of business consistent with past
         practice;

                                  (vi)  take any action which would result in
         any of the representations and warranties of ML set forth in this
         Agreement becoming untrue as of any date after the date hereof or in
         any of the conditions set forth in Article V hereof not being
         satisfied, except in each case as may be required by applicable law;

                                  (vii)  change any method, practice or
         principle of accounting, except as may be required from time to time
         by GAAP (without regard to any optional early adoption date) or any
         Regulatory Authority responsible for regulating ML or Main Line Bank;

                                  (viii)  waive, release, grant or transfer any
         rights of value or modify or change in any material respect any
         existing material agreement to which ML or any ML Subsidiary is a
         party, other than in the ordinary course of business consistent with
         past practice;

                                  (ix)  implement any pension, retirement,

                                       37

         that was not in effect on the date of this Agreement, or, except as
         required by law, materially amend any existing plan or arrangement
         except to the extent such amendments do not result in an increase in
         cost; provided, however, that ML may contribute to the ML pension plan
         an amount not to exceed the minimum amount required under ERISA or the
         IRC only if (A) such amount is usual and ordinary, consistent with
         past practice and (B) ML obtains an opinion of legal counsel that the
         full amount of such contribution will be deductible by ML for federal
         tax purposes;

                                  (x)  purchase any security for its investment
         portfolio not rated "A" or higher by either Standard & Poor's
         Corporation or Moody's Investor Services, Inc.;

                                  (xi)  amend or otherwise modify the
         underwriting and other lending guidelines and policies of Main Line

         lending activities in the ordinary course of business consistent with
         past practice;

                                  (xii)  enter into, renew, extend or modify
         any other transaction with any Affiliate, other than deposit and loan
         transactions in the ordinary course of business and which are in
         compliance with the requirements of applicable laws and regulations;

                                  (xiii)  enter into any interest rate swap,

                                  (xiv)  except for the execution of this
         Agreement, take any action that would give rise to a right of payment
         to any individual under any employment agreement;

                                  (xv)  take any action that would preclude the
         Merger from qualifying (A) for pooling-of-interests accounting
         treatment under GAAP or (B) as a reorganization within the meaning of
         Section 368 of the IRC, provided, however, that nothing contained
         herein shall limit the ability of ML to comply with its obligations
         under the Stock Option Agreement; or

                                  (xvi)  agree to do any of the foregoing.

                 For purposes of this Section 4.01, it shall not be considered
in the ordinary course of business for ML or any ML Subsidiary to do any of the
following:  (i) make any capital expenditure of $100,000 or more not disclosed
on ML Disclosure Schedule 4.01, without the prior written consent of Sovereign;
(ii) make any sale, assignment, transfer, pledge, hypothecation or other
disposition of any assets having a book or market value, whichever is greater,
in the aggregate in excess of $5,000,000,





                                       38
<PAGE>   44
other than pledges of assets to secure government deposits, to exercise trust
powers, sales of assets received in satisfaction of debts previously contracted
in the normal course of business, issuance and sales of loans, or transactions
in the investment securities portfolio by ML or a ML Subsidiary or repurchase
agreements, in each case, in the ordinary course of business; or (iii)
undertake or enter any lease, contract or other commitment for its account,
other than in the normal course of providing credit to customers as part of its
banking business, involving a payment by ML or any ML Subsidiary of more than
$100,000 annually, or containing a material financial commitment and extending
beyond 12 months from the date hereof.

                 Section 4.02  Access; Confidentiality.

                          (a)     From the date of this Agreement through the
Closing Date, ML or Sovereign, as the case may be, shall afford to, and shall
cause each ML Subsidiary or Sovereign Subsidiary to afford to, the other party
and its authorized agents and representatives, complete access to their
respective properties, assets, books and records and personnel, at reasonable
hours and after reasonable notice; and the officers of ML and Sovereign will
furnish any person making such investigation on behalf of the other party with
such financial and operating data and other information with respect to the
businesses, properties, assets, books and records and personnel as the person
making such investigation shall from time to time reasonably request.

                          (b)     ML and Sovereign each agree to conduct such
investigation and discussions hereunder in a manner so as not to interfere
unreasonably with normal operations and customer and employee relationships of
the other party.

                          (c)     In addition to the access permitted by
subparagraph (a) above, from the date of this Agreement through the Closing
Date, ML shall permit employees of Sovereign reasonable access to and
participation in matters relating to problem loans, loan restructurings and
loan work-outs of ML and the ML Subsidiaries, provided that nothing contained
in this subparagraph shall be construed to grant Sovereign or any Sovereign
employee any decision-making authority with respect to such matters.  Sovereign
shall have the right, however, at Sovereign's expense, to cause ML or any ML
Subsidiary to obtain an appraisal by an independent third party experienced in
such matters, and mutually satisfactory to Sovereign and ML, of the assets or
property securing any loan made by ML or any ML Subsidiary, with a principal
balance of $1.0 million or more.

                          (d)     All information furnished to Sovereign by ML
or by ML to Sovereign previously in connection with the transactions
contemplated by this Agreement or pursuant hereto shall be held in confidence
to the extent required by, and in accordance with, the





                                       39
<PAGE>   45
confidentiality agreements, dated August 20, 1997, between ML and Sovereign
(the "Confidentiality Agreements").

                 Section 4.03  Regulatory Matters and Consents.

                          (a)     ML and Sovereign shall promptly prepare a
Prospectus/Proxy Statement to be mailed to their respective shareholders in
connection with the meetings of their respective shareholders and transactions
contemplated hereby, and to be filed by Sovereign with the SEC in the
Registration Statement, which Prospectus/Proxy Statement shall conform to all
applicable legal requirements.  Sovereign shall, as promptly as practicable
following the preparation thereof, file the Registration Statement with the SEC
and ML and Sovereign shall use all reasonable efforts to have the Registration
Statement declared effective under the Securities Act as promptly as
practicable after such filing.  Sovereign will advise ML, promptly after
Sovereign receives notice thereof, of the time when the Registration Statement
has become effective or any supplement or amendment has been filed, of the
issuance of any stop order or the suspension of the qualification of the shares
of capital stock issuable pursuant to the Registration Statement, or the
initiation or threat of any proceeding for any such purpose, or of any request
by the SEC for the amendment or supplement of the Registration Statement or for
additional information.  Sovereign shall use its reasonable best efforts to
obtain, prior to the effective date of the Registration Statement, all
necessary state securities laws or "Blue Sky" permits and approvals required to
carry out the transactions contemplated by this Agreement.  Sovereign will
provide ML with as many copies of such Registration Statement and all
amendments thereto promptly upon the filing thereof as ML may reasonably
request.

                          (b)     Sovereign and ML will prepare all
Applications to Regulatory Authorities and make all filings for, and use their
reasonable best efforts to obtain as promptly as practicable after the date
hereof, all necessary permits, consents, approvals, waivers and authorizations
of all Regulatory Authorities necessary or advisable to consummate the
transactions contemplated by this Agreement.

                          (c)     ML will furnish Sovereign with all
information concerning ML and ML Subsidiaries as may be reasonably necessary or
advisable in connection with the Registration Statement and any Application or
filing made by or on behalf of Sovereign to any Regulatory Authority in
connection with the transactions contemplated by this Agreement and the Bank
Plan of Merger.

                          (d)     Sovereign and ML shall have the right to
review in advance, and to the extent practicable each will consult with the
other on, all information which appears in any filing made with or written
materials submitted to the SEC, any Regulatory Authority





                                       40
<PAGE>   46
or any third party in connection with the transactions contemplated by this
Agreement and the Bank Plan of Merger.  In exercising the foregoing right, each
of the parties hereto shall act reasonably and as promptly as practicable.  The
parties hereto agree that they will consult with each other with respect to the
obtaining of all permits, consents, approvals and authorizations of the SEC,
Regulatory Authorities and third parties necessary or advisable to consummate
the transactions contemplated by this Agreement and the Bank Plan of Merger and
each party will keep the other apprised of the status of matters relating to
completion of the transactions contemplated hereby and thereby.

                          (e)     Sovereign will promptly furnish ML with
copies of all Applications and other written communications to, or received by
Sovereign or any Sovereign Subsidiary from, any Regulatory Authority in respect
of the transactions contemplated hereby and the Bank Plan of Merger.

                 Section 4.04  Taking of Necessary Action.  Sovereign and ML
shall each use its reasonable best efforts in good faith, and each of them
shall cause its Subsidiaries to use their reasonable best efforts in good
faith, to take or cause to be taken all action necessary or desirable on its
part so as to permit completion of the Merger and the Bank Merger as soon as
practicable after the date hereof, including, without limitation, (A) obtaining
the consent or approval of each individual, partnership, corporation,
association or other business or professional entity whose consent or approval
is required or desirable for consummation of the transactions contemplated
hereby (including assignment of leases without any change in terms), provided
that neither ML nor any ML Subsidiary shall agree to make any payments or
modifications to agreements in connection therewith without the prior written
consent of Sovereign, and (B) requesting the delivery of appropriate opinions,
consents and letters from its counsel and independent auditors.  No party
hereto shall take, or cause, or to the best of its ability permit to be taken,
any action that would substantially impair the prospects of completing the
Merger and the Bank Merger pursuant to this Agreement and the Bank Plan of
Merger; provided that nothing herein contained shall preclude Sovereign or ML
or from exercising its rights under this Agreement or the Stock Option
Agreement.

                 Section 4.05  Indemnification; Insurance.

                          (a)     In the event of any threatened or actual
claim, action, suit, proceeding or investigation, whether civil, criminal or
administrative, in which any person who is now, or has been at any time prior
to the date of this Agreement, or who becomes prior to the Effective Date, a
director or officer or employee of ML or any of its Subsidiaries (the
"Indemnified Parties") is, or is threatened to be, made a party to a suit based
in whole or in part on, or arising in whole or in part out of, or pertaining to
(i) the





                                       41
<PAGE>   47
fact that he is or was a director, officer or employee of ML, any of the ML
Subsidiaries or any of their respective predecessors or (ii) this Agreement or
any of the transactions contemplated hereby, whether in any case asserted or
arising before or after the Effective Date, the parties hereto agree to
cooperate and use their best efforts to defend against and respond thereto to
the extent permitted by the BCL and the Articles of Incorporation and Bylaws of
ML.  On or after the Effective Date, Sovereign shall indemnify, defend and hold
harmless all prior and then-existing directors and officers of ML or of any ML
Subsidiary, against (i) all losses, claims, damages, costs, expenses,
liabilities or judgments or amounts that are paid in settlement (with the prior
approval of Sovereign) of or in connection with any claim, action, suit,
proceeding or investigation based in whole or in part on or arising in whole or
in part out of the fact that such person is or was a director, officer or
employee of ML or any ML Subsidiary, whether pertaining to any matter existing
or occurring at or prior to the Effective Date and whether asserted or claimed
prior to, or at or after, the Effective Date ("Indemnified Liabilities") and
(ii) all Indemnified Liabilities based in whole or in part on, or arising in
whole or in part out of, or pertaining to this Agreement or the transactions
contemplated hereby, to the same extent as such officer, director or employee
may be indemnified by ML or any ML Subsidiary as of the date hereof including
the right to advancement of expenses, provided, however, that any such officer,
director or employee of ML or any ML Subsidiary may not be indemnified by
Sovereign and/or Sovereign Bank if such indemnification is prohibited by
applicable law.

                          (b)     Sovereign shall maintain ML's existing
directors' and officers' liability insurance policy (or a policy providing
comparable coverage amounts on terms generally no less favorable, including
Sovereign's existing policy if it meets the foregoing standard) covering
persons who are currently covered by such insurance for a period of five years
after the Effective Date; provided, however, that in no event shall Sovereign
be obligated to expend, in order to maintain or provide insurance coverage
pursuant to this Section 4.05(b), any amount per annum in excess of 150% of the
amount of the annual premiums paid as of the date hereof by ML for such
insurance (the "Maximum Amount").  If the amount of the annual premiums
necessary to maintain or procure such insurance coverage exceeds the Maximum
Amount, Sovereign shall use all reasonable efforts to maintain the most
advantageous policies of directors' and officers' insurance obtainable for an
annual premium equal to the Maximum Amount.  In the event that Sovereign acts
as its own insurer for all of its directors and officers with respect to
matters typically covered by a directors' and officers' liability insurance
policy, Sovereign's obligations under this Section 4.05(b) may be satisfied by
such self insurance, so long as its senior debt ratings by Standard & Poor's
Corporation and Moody's Investors Services, Inc. are not lower than such
ratings as of the date hereof.

<PAGE>   48
                          (c)     In the event that Sovereign or any of its
respective successors or assigns (i) consolidates with or merges into any other
person and shall not be the continuing or surviving corporation or entity of
such consolidation or merger or (ii) transfers all or substantially all of its
properties and assets to any Person, then, and in each such case the successors
and assigns of such entity shall assume the obligations set forth in this
Section 4.05.

                 Section 4.06  No Other Bids and Related Matters.  So long as
this Agreement remains in effect, ML shall not and ML shall not authorize or
permit any of its directors, officers, employees or agents, to directly or
indirectly (i) respond to, solicit, initiate or encourage any inquiries
relating to, or the making of any proposal which relates to, an Acquisition
Transaction (as defined below), (ii) recommend or endorse an Acquisition
Transaction, (iii) participate in any discussions or negotiations regarding an
Acquisition Transaction, (iv) provide any third party (other than Sovereign or
an affiliate of Sovereign) with any nonpublic information in connection with
any inquiry or proposal relating to an Acquisition Transaction or (v) enter
into an agreement with any other party with respect to an Acquisition
Transaction.  Notwithstanding the foregoing, (i) for a period of 30 days after
the date of this Agreement, the Board of Directors of ML may respond to
unsolicited inquiries relating to an Acquisition Transaction or (ii) the Board
of Directors may recommend or endorse an Acquisition Transaction if, after
having consulted with and considered the written advice of its financial
advisers and outside counsel, it has determined in good faith that the failure
to do so would result in a reasonable likelihood that the directors, under the
BCL, have breached their fiduciary duty.  ML will immediately cease and cause
to be terminated any existing activities, discussions or negotiations
previously conducted with any parties other than Sovereign with respect to any
of the foregoing, and will take all actions necessary or advisable to inform
the appropriate individuals or entities referred to in the first sentence
hereof of the obligations undertaken in this Section 4.06.  ML will notify
Sovereign orally (within one day) and in writing (as promptly as practicable)
if any inquiries or proposals relating to an Acquisition Transaction are
received by, any such information is requested from, or any such negotiations
or discussions are sought to be initiated or continued with, ML.  As used in
this Agreement, "Acquisition Transaction" shall mean one of the following
transactions with a party other than Sovereign of an affiliate of Sovereign (i)
a merger or consolidation, or any similar transaction, involving ML or an ML
Subsidiary, (ii) a purchase, lease or other acquisition of all or a substantial
portion of the assets or liabilities of ML or an ML Subsidiary or (iii) a
purchase or other acquisition (including by way of share exchange, tender
offer, exchange offer or otherwise) of a substantial interest in any class or
series of equity securities of ML (other than as permitted by Section
4.01(a)(ii) hereof) or an ML Subsidiary.

                 Section 4.07  Duty to Advise; Duty to Update Disclosure
Schedule.  Each party shall promptly advise the other party of any change or
event having a Material Adverse Effect on it or which it believes would or
would be reasonably likely to cause or constitute a material breach of any of
its representations, warranties or covenants set forth herein.  Each party
shall update its respective Disclosure Schedule as promptly as practicable
after the occurrence of an event or fact which, if such event or fact had
occurred prior to the date of this Agreement, would have been disclosed in such
Disclosure Schedule.  The delivery of such updated Schedule shall not relieve a
party from any breach or violation of this Agreement and shall not have any
effect for the purposes of determining the satisfaction of the condition set
forth in Section 5.01(c) or 5.02(c) hereof, as applicable.

                 Section 4.08  Conduct of Sovereign's Business.

                          (a)     From the date of this Agreement to the
Closing Date, Sovereign will use its best efforts to (x) preserve its business
organizations intact, (y) maintain good relationships with employees, and (z)
preserve for itself the goodwill of customers of Sovereign and Sovereign
Subsidiaries and others with whom business relationships exist.

                          (b)     Except with the prior written consent of ML
or as expressly contemplated hereby, between the date hereof and the Effective
Date, Sovereign shall not, and shall cause each Sovereign Subsidiary not to:

                                  (i)  declare, set aside, make or pay any
         extraordinary cash dividend or other distribution of cash or property
         in respect of the Sovereign Common Stock, except for stock dividends
         and regular quarterly cash dividends, provided, however, that nothing
         contained herein shall be deemed to affect the ability of a Sovereign
         Subsidiary to pay dividends on its capital stock to Sovereign;

                                  (ii)  amend its Articles of Incorporation or
         equivalent document or Bylaws in a manner which would adversely affect
         in any manner the terms of the Sovereign Common Stock or the ability
         of Sovereign or Sovereign Bank to consummate the transactions
         contemplated hereby;

                                  (iii)  take any action that would preclude
         the Merger from qualifying (A) for pooling-of-interests accounting
         treatment under GAAP or (B) as a reorganization within the meaning of
         Section 368 of the IRC; provided, however, that nothing contained
         herein shall limit the ability of Sovereign to exercise its rights
         under the Stock Option Agreement;

                                  (iv)  take any action which would result in
         any of the representations and warranties of Sovereign contained





                                       44
<PAGE>   50
         in this Agreement becoming untrue as of any date after the date hereof
         or in any of the conditions set forth in Article V hereof not being
         satisfied, except in each case as may be required by applicable law;
         or

                                  (v)  agree to do any of the foregoing.

                 Section 4.09  Current Information.

                          (a)     During the period from the date of this
Agreement to the Effective Date, each party shall, upon the request of the
other party, cause one or more of its designated representatives to confer on a
monthly or more frequent basis with representatives of the other party
regarding its financial condition, operations and business and matters relating
to the completion of the transactions contemplated hereby.  As soon as
reasonably available, but in no event more than 45 days after the end of each
calendar quarter ending after the date of this Agreement (other than the last
quarter of each fiscal year ending December 31 in the case of Sovereign and
March 31 in the case of ML), ML and Sovereign will deliver to the other party
its quarterly report on Form 10-Q under the Exchange Act, and, as soon as
reasonably available, but in no event more than 90 days after the end of each
fiscal year ended December 31 in the case of Sovereign and March 31 in the case
of ML, ML and Sovereign will deliver to the other party its Annual Report on
Form 10-K.  Within 25 days after the end of each month, ML and Sovereign will
deliver to the other party a consolidated balance sheet and a consolidated
statement of operations, without related notes, for such month.

                          (b)     Each party shall provide to the other party a
copy of the minutes of any meeting of the Board of Directors of such party or
any Subsidiary thereof, or any committee thereof, or any senior management
committee, promptly after such minutes are approved at a subsequent meeting of
the board or committee, but in any event within 40 days of the meeting of such
board or committee to which such minutes relate, except that with respect to
any meeting held within 30 days of the Closing Date, such minutes shall be
provided prior to the Closing Date.

                 Section 4.10  Undertakings by Sovereign and ML.

                          (a)     From and after the date of this Agreement, ML
shall:

                                  (i)  Phase I Environmental Audit.  Permit
         Sovereign, if Sovereign elects to do so, at its own expense, to cause
         a "phase I environmental audit" to be performed at any physical
         location owned or occupied by ML or any ML Subsidiary on the date
         hereof;





                                       45
<PAGE>   51
                                  (ii)  Approval of Bank Plan of Merger.
         Approve the Bank Plan of Merger as sole shareholder of Main Line Bank
         and obtain the approval of, and cause the execution and delivery of,
         the Bank Plan of Merger by Main Line Bank;

                                  (iii)  Timely Review.  If requested by
         Sovereign at Sovereign's sole expense, cause its independent certified
         public accountants to perform a review of its unaudited consolidated
         financial statements as of the end of any calendar quarter, in
         accordance with Statement of Auditing Standards No. 36, and to issue
         its report on such financial statements as soon as is practicable
         thereafter;

                                  (iv)  Outside Service Bureau Contracts.  If
         requested to do so by Sovereign, use its reasonable best efforts to
         obtain an extension of any contract with an outside service bureau or
         other vendor of services to ML or any ML Subsidiary, on terms and
         conditions mutually acceptable to ML and Sovereign;

                                  (v)  List of Nonperforming Assets.  Provide
         Sovereign, within fifteen (15) days after the quarterly meeting of its
         Asset Review Committee, a written list of nonperforming assets as of
         the end of such month; and

                                  (vi)  Reserves and Merger-Related Costs.  On
         or before the Effective Date, establish such additional accruals and
         reserves as may be necessary to conform the accounting reserve
         practices and methods (including credit loss practices and methods) of
         ML to those of Sovereign (as such practices and methods are to be
         applied to ML from and after the Closing Date) and Sovereign's plans
         with respect to the conduct of the business of ML following the Merger
         and otherwise to reflect Merger-related expenses and costs incurred by
         ML, provided, however, that ML shall not be required to take such
         action (A) more than five (5) days prior to the Effective Date; and
         (B) unless Sovereign agrees in writing that all conditions to closing
         set forth in Section 5.02 have been satisfied or waived (except for
         the expiration of any applicable waiting periods); prior to the
         delivery by Sovereign of the writing referred to in the preceding
         clause, ML shall provide Sovereign a written statement, certified
         without personal liability by the chief executive officer of ML and
         dated the date of such writing, that the representation made in
         Section 2.15 hereof is true as of such date or, alternatively, setting
         forth in detail the circumstances that prevent such representation
         from being true as of such date.  No accrual or reserve made by ML or
         any ML Subsidiary pursuant to this subsection, or any litigation or
         regulatory proceeding arising out of any such accrual or reserve,
         shall constitute or be deemed to be a breach or violation of any
         representation, warranty, covenant, condition or other provision of
         this





                                       46
<PAGE>   52
         Agreement or to constitute a termination event within the meaning of
         Section 6.01(d) hereof.

                          (b)     From and after the date of this Agreement,
Sovereign and ML shall each:

                                  (i)  Shareholders Meetings.  Each of ML and
         Sovereign shall take all action necessary to properly call and convene
         a special meeting of its shareholders as soon as practicable after the
         date hereof to consider and vote upon this Agreement and the
         transactions contemplated hereby.  The Board of Directors of ML and
         the Board of Directors of Sovereign will recommend that the
         shareholders of ML and Sovereign, respectively, approve this Agreement
         and the transactions contemplated hereby, provided that the Board of
         Directors of ML or the Board of Directors of Sovereign may fail to
         make such recommendation, or withdraw, modify or change any such
         recommendation, if such Board of Directors, after having consulted
         with and considered the written advice of its financial advisers and
         outside counsel, has determined that the making of such
         recommendation, or the failure to withdraw, modify or change such
         recommendation, would result in a reasonable likelihood that the
         directors, under the BCL, have breached their fiduciary duty.  If
         required by the other party, a party shall retain a proxy solicitor in
         connection with the solicitation of the approval of its shareholders
         of this Agreement and the transactions contemplated hereby.

                                  (ii)  Public Announcements.  Cooperate and
         cause its respective officers, directors, employees and agents to
         cooperate in good faith, consistent with their respective legal
         obligations, in the preparation and distribution of, and agree upon
         the form and substance of, any press release related to this Agreement
         and the transactions contemplated hereby, and any other public
         disclosures related thereto, including without limitation,
         communications to ML shareholders and ML's internal announcements and
         customer disclosures, but nothing contained herein shall prohibit
         either party from making any disclosure which its counsel deems
         necessary under applicable law;

                                  (iii)  Maintenance of Insurance.  Maintain,
         and cause their respective Subsidiaries to maintain, insurance in such
         amounts as are reasonable to cover such risks as are customary in
         relation to the character and location of its properties and the
         nature of its business;

                                  (iv)  Maintenance of Books and Records.
         Maintain, and cause their respective Subsidiaries to maintain, books
         of account and records in accordance with GAAP applied on a basis
         consistent with those principles used in preparing the financial
         statements heretofore delivered;





                                       47
<PAGE>   53
                                  (v)  Delivery of Securities Documents.
         Deliver to the other, copies of all Securities Documents
         simultaneously with the filing thereof; and

                                  (vi)  Taxes.  File all federal, state, and
         local tax returns required to be filed by them or their respective
         Subsidiaries on or before the date such returns are due (including any
         extensions) and pay all taxes shown to be due on such returns on or
         before the date such payment is due.

                 Section 4.11  Employee Benefits and Termination Benefits.

                          (a)     Employee Benefits.  On and after the
Effective Date, the employee pension and welfare benefit plans of Sovereign and
ML (as well as any other plan of ML providing for benefits not subject to
ERISA) may, at Sovereign's election and subject to the requirements of the IRC,
continue to be maintained separately or consolidated, except as set forth
below.  In connection with implementation of the foregoing, the following
provisions and guidelines shall apply:

                                  (i)  Sovereign Employee Stock Ownership Plan
         ("ESOP").  Employees of ML and ML Subsidiaries who become employees of
         Sovereign or a Sovereign Subsidiary shall become entitled to
         participate in the Sovereign ESOP in accordance with its terms by
         treating them as newly employed individuals without any prior service
         credit under such plan.

                                  (ii)  ML ESOP.

                                        (A)     Each participant in the ML
                 Employee Stock Ownership Plan ("ML ESOP") not fully vested
                 will, in accordance with the terms of the ML ESOP, become
                 fully vested in his or her ML ESOP account as of the Effective
                 Date.  As soon as practicable after the execution of this
                 Agreement, ML, Main Line Bank and Sovereign will cooperate to
                 cause the ML ESOP to be amended and other action taken, in a
                 manner reasonably acceptable to ML and Sovereign, to provide
                 that the ML ESOP will terminate upon the Effective Date.
                 Between the date hereof and the Effective Date, the existing
                 ML ESOP indebtedness shall be paid in the ordinary course of
                 business and ML or Main Line Bank shall make such
                 contributions to the ML ESOP as necessary to fund such
                 payments.  Any indebtedness of the ML ESOP remaining as of the
                 Effective Date shall be repaid from the Trust associated with
                 the ML ESOP through application or sale of the Sovereign
                 Common Stock received by the ML ESOP; provided, however, that
                 (i) any related sale or distribution of shares by the ML ESOP
                 shall be effected in accordance with the requirements of
                 federal and any applicable state securities laws and
                 regulations, including any rules of the NASD, (ii) any





                                       48
<PAGE>   54
                 related sale or distribution of shares by the ML ESOP and any
                 participant shall be effected in such a manner (and with such
                 safeguards as may be necessary or appropriate) so as not to
                 jeopardize the intended "pooling of interests" accounting
                 treatment of the Merger, and (iii) all distributions from the
                 ML ESOP after the Effective Date shall be in shares of
                 Sovereign Common Stock.  Upon the repayment of the ML ESOP
                 loan, the remaining funds in the ML ESOP suspense account will
                 be allocated (to the extent permitted by Sections 401(a), 415
                 or 4975 of the IRC and the applicable laws and regulations
                 including, without limitation, the applicable provisions of
                 ERISA) to ML ESOP participants (as determined under the terms
                 of the ML ESOP).  ML and Sovereign agree that, subject to the
                 conditions described herein, as soon as practicable after the
                 Effective Date and repayment of the ML ESOP loan, participants
                 in the ML ESOP shall be entitled at their election to have the
                 amounts in their ML ESOP accounts either distributed to them
                 in a lump sum or rolled over to another tax-qualified plan
                 (including Sovereign plans to the extent permitted by
                 Sovereign) or individual retirement account.

                                        (B)     The actions relating to
                 termination of the ML ESOP will be adopted conditioned upon
                 the consummation of the Merger and upon receiving a favorable
                 determination letter from the Internal Revenue Service ("IRS")
                 with regard to the continued qualification of the ML ESOP
                 after any required amendments.  ML and Sovereign will
                 cooperate in submitting appropriate requests for any such
                 determination letter to the IRS and will use their best
                 efforts to seek the issuance of such letter as soon as
                 practicable following the date hereof.  ML and Sovereign will
                 adopt such additional amendments to the ML ESOP as may be
                 reasonably required by the IRS as a condition to granting such
                 determination letter, provided that such amendments do not (i)
                 substantially change the terms outlined herein, (ii) have a
                 Material Adverse Effect on ML or (iii) result in an additional
                 material liability to Sovereign.

                                        (C)     As of and following the
                 Effective Date, Sovereign shall cause the ML ESOP to be
                 maintained for the exclusive benefit of employees and other
                 persons who were participants or beneficiaries therein prior
                 to the Effective Date and proceed with termination of the ML
                 ESOP through distribution of its assets in accordance with its
                 terms subject to the amendments described herein and as
                 otherwise may be required to comply with applicable law or to
                 obtain a favorable determination from the IRS as to the
                 continuing qualified status of the





                                       49
<PAGE>   55
                 ML ESOP, provided, however, that no such termination
                 distributions of the ML ESOP shall occur after the Effective
                 Date until a favorable termination letter has been received
                 from the IRS.

                                  (iii)  Sovereign Defined Benefit Pension Plan
         ("DB Plan").  Employees of ML and ML Subsidiaries who become employees
         of Sovereign or a Sovereign Subsidiary shall become entitled to
         participate in Sovereign's DB Plan in accordance with its terms.  In
         this regard, each such employee shall (A) receive, for purposes of
         participation and vesting only, credit for all service with ML or an
         ML Subsidiary credited to each such employee under ML's DB Plan as of
         the date of its termination or cessation of accrual of benefits, and
         (B) enter the Sovereign DB Plan on the entry date concurrent with or
         next following the employee's satisfaction of such plan's minimum
         participation requirements.

                                  (iv)  ML DB Plan.  ML may proceed with the
         presently contemplated termination and/or cessation of the accrual of
         benefits under its DB Plan and allocation of excess benefits and
         Sovereign shall take no action inconsistent therewith if the DB Plan
         is not terminated and allocation of excess benefits thereunder are not
         completed prior to the Effective Date, it being the intention of the
         parties that such actions be taken after the Effective Date under such
         circumstances.  No termination or cessation distribution shall be made
         until ML or Sovereign has received a favorable determination letter
         from the IRS.

                                  (v)  Sovereign 401(k) Retirement Savings Plan
         ("401(k) Plan").  Employees of ML and ML Subsidiaries who become
         employees of Sovereign or a Sovereign Subsidiary shall become entitled
         to participate in the Sovereign 401(k) Plan in accordance with its
         terms.  In this regard, each such employee shall (A) receive, for
         purposes of participation and vesting only, credit for all service
         with ML or an ML Subsidiary credited to each such employee under ML's
         401(k) Plan as of the date of the date of the Merger, and (B) enter
         the Sovereign 401(k) Plan on the entry date concurrent with or next
         following the employee's satisfaction of such plan's minimum
         participation requirements.

                                  (vi)  ML Savings Plan ("401(k) Plan").
         Following the Merger, Sovereign will initially continue to maintain
         ML's 401(k) Plan until its participants generally become eligible to
         participate in the Sovereign 401(k) Plan.  Thereafter, Sovereign shall
         have the right, but not the obligation, to combine the two plans on
         such terms as it deems appropriate and in accordance with applicable
         law.





                                       50

                                  (vii)  Sovereign and ML Nonqualified Deferred
         Compensation Plans ("Excess Benefit Plans").  Following the Merger,
         Sovereign will, as soon as administratively feasible, consolidate the
         Excess Benefit Plans maintained by Sovereign and ML to supplement
         certain pension benefits lost by some employees by reason of
         limitations contained in the IRC.  Such consolidation shall be
         effected in such a manner that no person receive redundant benefits or
         lose existing benefits.  The intent of the preceding sentence is that
         affected employees of ML and ML Subsidiaries generally shall be
         entitled only to the sum of (A) the benefits accrued under the ML
         Excess Benefit Plan(s) as of the plan consolidation, and (B) the
         benefits accrued thereafter under the combined Excess Benefit Plan.

                                  (viii)  ML Recognition and Retention Plan
         ("RRP").  The RRP shall continue in effect following the Effective
         Date as a Sovereign plan.  No action shall be taken that would
         adversely affect the rights of plan participants who hold outstanding
         grants or awards of shares of ML Common Stock, whether before or after
         the Effective Date.  Except as expressly permitted by this Agreement,
         no further grants or awards shall be made under the RRP following the
         date of this Agreement.  Any shares of ML Common Stock outstanding
         under such Plan's related trust, but not subject to a grant or award,
         shall be converted into Sovereign Common Stock as of the Effective
         Date.

                                  (ix)  Welfare Benefit Plans.  Following the
         Merger, the welfare benefit plans of Sovereign and ML (and their
         respective subsidiaries) shall initially remain unchanged.  Sovereign
         shall undertake a study, in consultation with appropriate professional
         advisors, with a view toward the possible combination of some or all
         of such plans or the benefits provided thereunder.  Following such
         study, Sovereign shall take such action with respect to such plans
         (which may include the implementation of new benefits, reduction or
         elimination of some benefits, and the alteration of the respective
         cost allocation between employer and employee) as it deems appropriate
         under the circumstances.

                                  (x)  ML Bonus Plans and Arrangements.  ML may
         continue to administer such bonus programs and arrangements as are
         disclosed pursuant to this Agreement through the Effective Date, with
         such equitable modifications as may be appropriate to take into
         account the circumstances of the Merger and the timing thereof.  In
         the event the Merger shall occur after such current fiscal year,
         bonuses shall be provided on a pro rata basis with respect to the
         interim period; provided, however, that bonuses for such interim
         period, in the aggregate, shall not exceed $200,000.

                                  (xi)  Employer Loan Program.  Prior to
         consummation of the Merger, Main Line Bank may continue to originate
         loans pursuant to its employee loan program in effect as of the date
         hereof, as disclosed pursuant to this Agreement, and upon consummation
         of the Bank Merger, Sovereign agrees to cause Sovereign Bank to honor
         all of the loans originated by Main Line Bank pursuant to such
         employee loan program or its predecessors.

                                  (xii)  Other ML Plans.  From the date of this
         Agreement through the Effective Date of the Merger, without the prior
         written consent of Sovereign and except as otherwise expressly
         permitted by this Agreement, no further benefits, grants or awards
         shall be made available under any other ML plans to employees or
         directors, including, without limitation, the granting of stock
         options, stock appreciation rights, restricted stock, and performance
         shares.

                          (b)     Severance Policy.  Sovereign agrees to cause
Sovereign Bank to provide the severance pay and benefits specified in the Main
Line Bank severance policy to any employee of Main Line Bank whose employment
is terminated in connection with the Merger within three (3) months of the
Effective Date, either because such employee's position is eliminated or such
employee is not offered comparable employment (i.e., not offered employment for
a position of generally similar job description or responsibilities in a
location within 65 miles from ML's headquarters), excluding any employee who
has an existing employment or special termination agreement or whose employment
is terminated for Cause (as defined below).  For purposes of this Section
4.11(b), "Cause" shall mean termination because of the employee's personal
dishonesty, incompetence, willful misconduct, breach of fiduciary duty
involving personal profit, intentional failure to perform stated duties or
willful violation of any law, rule or regulation (other than traffic violations
or similar offenses).  The benefits provided to terminated ML and Main Line
Bank employees under this subsection are the only severance benefits payable by
ML or Main Line Bank under any plan or policy (excluding severance benefits
provided under existing employment or special termination agreements or as
otherwise required by law) and shall be in lieu of any termination benefits to
which such employees would otherwise be entitled under Sovereign's or Sovereign
Bank's severance policies or programs then in effect.  ML shall amend its
severance policy, to the extent reasonably necessary, so that the effect of its
administration shall not be in conflict with the provisions of this Agreement,
including, without limitation, provisions relating to bonuses and out-placement
services.

                          (c)     Intention Regarding Future Employment.
Within ninety (90) days of the date hereof, Sovereign and Sovereign Bank shall
use their reasonable best efforts to inform the employees of ML and Main Line
Bank of the likelihood of such employees having





                                       52
<PAGE>   58
continued employment with Sovereign Bank following the Effective Date and,
where appropriate, shall use their reasonable best efforts to interview the ML
and Main Line Bank employees to determine if there are mutually beneficial
employment opportunities available at Sovereign Bank.  It is the intent of
Sovereign Bank in connection with reviewing applicants for employment positions
to give any Main Line Bank employee who is terminated in connection with the
Merger within three (3) months of the Effective Date the same consideration as
is afforded Sovereign Bank employees for such positions in accordance with
existing formal or informal polices for a period of three (3) months from such
date of termination.

                          (d)  Employment and Other Contracts.  Sovereign
agrees to honor all employment contracts, consulting contracts and other
special termination agreements that ML and the ML Subsidiaries have with their
current or former employees and which have been disclosed to Sovereign pursuant
to this Agreement.

                          (e)  Retention Bonuses.  Each employee of ML or one
of the ML Subsidiaries identified in the ML Disclosure Schedule shall be
entitled to receive a "retention" bonus from ML or Main Line Bank equal to no
more than six (6) months of such employee's annual base salary as of the date
of this Agreement in the event that such employee remains an employee of ML or
one of the ML Subsidiaries, as applicable, until the Effective Date (or in
certain cases, the date the systems conversion occurs after the Effective Date)
and satisfactorily fulfills the duties and responsibilities of the position of
such employee of ML or one of the ML Subsidiaries, as the case may be, through
the Effective Date; provided that retention bonuses, in the aggregate, shall
not exceed $350,000.

                          (f)  Out-Placement.  Sovereign shall pay the cost of
out-placement services for employees who are terminated without Cause (as
defined in Section 4.11(b)) in connection with the Merger within three (3)
months after the Effective Date.  Sovereign shall not be obligated to pay any
out-placement fees in connection with the foregoing or more than $50,000 in the
aggregate for such services.

                 Section 4.12     Stock Exchange Listing.  Sovereign shall use
all reasonable efforts to cause the shares of Sovereign Common Stock to be
issued in connection with the Merger to be approved for quotation on the Nasdaq
Stock Market's National Market, subject to official notice of issuance, as of
or prior to the Effective Date.

                 Section 4.13     Affiliate Letters.

                          (a)  Each party has provided to the other party a
schedule of each person that, to the best of its knowledge, is deemed to be an
"Affiliate" of it, as that term is used in Rule 145 under the Securities Act or
Accounting Series Releases 130 and 135 of the Commission.

                          (b)  Each of ML and Sovereign shall use its 
reasonable best efforts to cause each person who may be deemed to be an
Affiliate of ML and Sovereign respectively, to execute and deliver to Sovereign
as soon as practicable after the date of this Agreement, and in any event prior
to the date of the meetings of shareholders of ML and Sovereign to be called
pursuant to Section 4.10(b)(i) hereof, a written agreement in the form of
Exhibit 1-A and 1-B in the case of Affiliates of ML and Sovereign,
respectively.

                 Section 4.14     Directors and Officers.

                          (a)  Effective as of the effective date of the Bank
Merger, Sovereign shall cause Sovereign Bank to elect or appoint Dennis S.
Marlo as President of the Pennsylvania Division of Sovereign Bank, which shall
consist of all Pennsylvania and Delaware branches of Sovereign Bank existing at
the Effective Date.

                          (b)  Sovereign and Sovereign Bank shall use their
reasonable best efforts to enter into a new employment agreement with Dennis S.
Marlo substantially in the form set forth in the ML Disclosure Schedule, with
such other changes thereto as may be mutually agreed upon by Sovereign,
Sovereign Bank and Mr. Marlo, effective as of the effective date of the Bank
Merger.

                          (c)  On the effective date of the Bank Merger, the
directors of Sovereign Bank, as the surviving institution in the Bank Merger,
shall consist of (i) those persons holding such office immediately prior to the
effective date of the Bank Merger and (ii) Dennis S. Marlo, who shall be
appointed as a director of Sovereign Bank effective as of the effective date of
the Bank Merger.  Mr. Marlo shall be appointed to hold office until the 1999
annual reorganization meeting of the Board of Directors of Sovereign Bank and
until his successor is elected and qualified.  Sovereign agrees to cause Mr.
Marlo, so long as he remains an active employee of Sovereign or Sovereign Bank,
to be renominated as a director of Sovereign Bank for election at the 1999 and
2000 annual reorganization meetings of the Board of Directors of Sovereign Bank
and agrees to vote its shares of Sovereign Bank in favor of such election at
such meetings.

                          (d)  On the effective date of the Bank Merger, the
officers of Sovereign Bank shall be (i) the officers of Sovereign Bank, as the
surviving corporation in the Bank Merger, immediately





                                       54
<PAGE>   60
prior to such effective date, and (ii) Dennis S. Marlo, who shall be appointed
as President of the Pennsylvania Division of Sovereign Bank effective as of the
effective date of the Bank Merger.

                          (e)     On the Effective Date, Sovereign Bank shall
establish for a period of at least two years the Pennsylvania Division of
Sovereign Bank Advisory Board (the "Advisory  Board"), which shall consist of
all non-employee members of the ML Board of Directors immediately prior to the
Effective Date.  The members of the Advisory Board shall be paid an annual
retainer of $18,750 ($25,000 in the case of John Eppinger).

                 Section 4.15  Sovereign Rights Agreement.  Sovereign agrees
that any Sovereign Rights issued pursuant to the Sovereign Rights Agreement
shall be issued with respect to each share of Sovereign Common Stock issued
pursuant to the terms hereof regardless whether there has occurred a
"Distribution Date" under the terms of such Sovereign Rights Agreement prior to
the Effective Date, as well as to take all action necessary or advisable to
enable the holder of each such share of Sovereign Common Stock to obtain the
benefit of such Sovereign Stock Purchase Rights notwithstanding their prior
distribution, including without limitation, amendment of the Sovereign Rights
Agreement.

                 Section 4.16  ML Share Issuance.  After ML and Sovereign
shareholder approval of the Merger and prior to the Effective Date, ML shall
use its reasonable best efforts to offer and sell for fair value to individuals
or entities unaffiliated with ML and Sovereign such number of shares of ML
Common Stock as shall be sufficient, in the opinion of Sovereign's and ML's
independent accountants, require the Merger to be accepted for as a
pooling-of-interests under GAAP.  ML shall consult with Sovereign with respect
to the amount of shares to be sold and the timing and manner of such sale,
which may involve placement agents or, with Sovereign's consent, underwriters.
If Sovereign receives from its independent certified public accountants written
advice that ML cannot sell a sufficient number of shares to satisfy the
requirements of this Section, then Sovereign, to ensure that the Merger will
not fail to qualify for pooling-of-interests accounting treatment, whether in
conjunction with the aforementioned ML share issuance or otherwise, shall use
its reasonable best efforts to offer and sell for fair value to individuals or
entities unaffiliated with ML and Sovereign all or part of the shares of ML
Common Stock held by it if such offer and sale would ensure that the Merger
will not fail to qualify for pooling-of-interests accounting treatment.

warranty (i) which specifically relates to an earlier date or (ii) where the

Agreement shall have been approved by the shareholders of Sovereign by such

                       TERMINATION, WAIVER AND AMENDMENT

                 Section 6.01  Termination.  This Agreement may be terminated
on or at any time prior to the Closing Date:

                          (a)     By the mutual written consent of the parties
hereto;

                          (b)     By Sovereign or ML:

                                  (i)  if the Closing Date shall not have
         occurred on or before May 31, 1998, unless the failure of such
         occurrence shall be due to the failure of the party seeking to
         terminate this Agreement to perform or observe in any material respect
         its agreements set forth in this Agreement required to





                                       59
<PAGE>   65
        be performed or observed by such party on or before the Closing Date; or

                                  (ii)  if either party has received a final
         unappealable administrative order from a Regulatory Authority whose
         approval or consent has been requested that such approval or consent
         will not be granted, or in the case of a termination by Sovereign,
         will not be granted absent the imposition of terms and conditions
         which would permit satisfaction of the condition set forth at Section
         5.02(d) hereof, unless the failure of such occurrence shall be due to
         the failure of the party seeking to terminate this Agreement to
         perform or observe in any material respect its agreements set forth
         herein required to be performed or observed by such party on or before
         the Closing Date; or

                          (c)     By ML, at any time during the ten-day period
following the Determination Date if both of the following conditions are
satisfied:

                                  (1)      the Sovereign Market Value shall be
         less than $12.18 and Sovereign shall make the election specified in
         the proviso clause to Section 1.02(e)(ii)(A)(ii) hereof; and

                                  (2)      (i) the quotient obtained by
         dividing the Sovereign Market Value by $16.24 (such number being
         referred to herein as the "Sovereign Ratio") shall be less than (ii)
         the quotient obtained by dividing the Index Price on the Determination
         Date by the Index Price on the Starting Date and subtracting 0.10 from
         the quotient in this clause (2)(ii);

subject, however, to the following:  If ML shall elect to terminate this
Agreement pursuant to this Section 6.01(c), it shall give written notice
thereof to Sovereign (provided that such notice of election to terminate may be
withdrawn at any time within the aforementioned ten-day period).  During the
five-day period commencing with its receipt of such notice, Sovereign shall
have the option to elect to increase the Exchange Ratio to equal the number
(rounded to the nearest hundredth) obtained by dividing $23.05 by the Sovereign
Market Value and the Closing Date shall be postponed by the minimum amount of
time necessary, if any, to accommodate Sovereign's election of such option
(i.e. up to a five-day period).  If Sovereign so elects within such five-day
period, it shall give prompt written notice to ML of such election and the
Exchange Ratio, whereupon no termination shall have occurred pursuant to this
Section 6.01(c) and this Agreement shall remain in effect in accordance with
its terms (except as the Exchange Ratio shall have been so modified), and any
references in this Agreement to "Exchange Ratio" or "Applicable Exchange Ratio"
shall thereafter be deemed to refer to the Exchange Ratio as adjusted pursuant
to this Section 6.01(c).

                          (d)     at any time on or prior to the Effective
Date, by ML in writing if Sovereign has, or by Sovereign in writing if ML has,
in any material respect, breached (i) any material covenant or undertaking
contained herein or (ii) any representation or warranty contained herein, which
in the case of a breach by Sovereign would have a Material Adverse Effect on
Sovereign and in the case of a breach by ML would have a Material Adverse
Effect on ML, in any case if such breach has not been substantially cured by
the earlier of 30 days after the date on which written notice of such breach is
given to the party committing such breach or the Effective Date or if on such
date such breach no longer causes a Material Adverse Effect; or

                          (e)     by either the Board of Directors of Sovereign
or the Board of Directors of ML if the Board of Directors of the other party

become void (other than Section 4.02(d) and Section 7.01 hereof, which shall

the part of Sovereign or ML to the other, except for any liability arising out
of any uncured willful breach of any covenant or other agreement contained in
this Agreement, any fraudulent breach of a representation or warranty, in this
Agreement and any obligation or liability arising under the Stock Option
Agreement.  Nothing contained in this Section 6.02 shall be deemed to prohibit
Sovereign or ML from maintaining an action against a third party for tortious
interference or otherwise.

extend the time for the performance of any of the obligations or other acts of
either party hereto, (c) waive any inaccuracies in the representations and
warranties contained herein or in any document delivered pursuant hereto, or
(d) waive compliance with any of the agreements or conditions contained in
Articles IV and V hereof or otherwise, provided that any amendment, extension
or waiver granted or executed after shareholders of ML or Sovereign have
approved this Agreement shall not modify either the amount or the form of the
consideration to be provided hereby to holders of ML Common Stock upon
consummation of the Merger or otherwise materially adversely affect the
shareholders of ML or Sovereign without the approval of the shareholders who
would be so affected.  This Agreement may not be amended except by an
instrument in writing authorized by the respective Boards of Directors and
signed, by duly authorized officers, on behalf of the parties hereto.  Any
agreement on the part of a party hereto to any extension or waiver shall be
valid only if set forth in an instrument in writing signed by a duly authorized
officer on behalf of such party, but such waiver or failure to insist on strict
compliance with such obligation, covenant, agreement or condition shall not
operate as a waiver of, or estoppel with respect to, any subsequent or other
failure.

                 Section 7.04  Entire Agreement.  This Agreement, including the
documents and other writings referred to herein or delivered pursuant hereto,

its subject matter.  This Agreement supersedes all prior arrangements and
understandings between the parties, both written or oral with respect to its
subject matter.  This Agreement shall inure to the benefit of and be binding
upon the parties hereto and their respective successors; provided, however,
that nothing in this Agreement, expressed or implied, is intended to confer
upon any party, other than the parties hereto and their respective successors,
any rights, remedies, obligations or liabilities other than pursuant to
Sections 1.02(f) and (g), 4.05, 4.11(d) and 4.14.

                 Section 7.05  No Assignment.  Neither party hereto may assign
any of its rights or obligations hereunder to any other person, without the
prior written consent of the other party hereto.

                 Section 7.08  Accountants.  In the event that the conditions 
to closing specified in Section 5.01(j) and 5.02(j) are not satisfied because 
either (but not both) Ernst & Young or KPMG Peat Marwick is unable to deliver
the letter required by such sections, then the parties hereto agree to appoint
another national accounting firm mutually acceptable to each party to determine
if the Merger is required to be accounted for as a pooling-of-interests.  The
written determination by such national accounting firm shall be binding on both
parties for purposes of determining whether the conditions contained in 
Section 5.01(j) and 5.02(j) has been satisfied.  In the event that the
provisions of this Section 7.08 become applicable, the date specified in
Section 6.01(b)(i) shall be extended until the earlier of (i) the date of the
written determination by such national accounting firm or (ii) June 30, 1998.

                 Section 7.09  Counterparts.  This Agreement may be executed in

original instrument, but all such counterparts together shall constitute but
one agreement.

                 Section 7.10  Severability.  If any provision of this
Agreement or the application thereof to any person or circumstance shall be
invalid or unenforceable to any extent, the remainder of this Agreement and the
application of such provisions to other persons or circumstances shall not be
affected thereby and shall be enforced to the greatest extent permitted by law.

                 Section 7.11  Governing Law.  This Agreement shall be governed
by and construed in accordance with the domestic internal law (including the
law of conflicts of law) of the Commonwealth of Pennsylvania.

                 IN WITNESS WHEREOF, the parties have caused this Agreement to

stock or shares of Sovereign common stock which, in Sovereign's sole judgment,
are individually and in the aggregate de minimis within the meaning of Topic
2-E of the Staff Accounting Bulletin Series of the SEC;

                 (h)      Agrees that neither ML nor Sovereign shall be bound
by any attempted sale of any shares of ML common stock or Sovereign common

among other things, for the acquisition by Sovereign of ML through the merger
of ML with and into Sovereign, with Sovereign surviving the merger (the
"Merger").

                 2.       As a condition to Sovereign to enter into the Plan,
ML is granting to Sovereign an option to purchase up to that number of shares
of common stock, par value $.01 per share (the "Common Stock") of ML as shall
equal 19.9% of shares of Common Stock of ML issued and outstanding as of the
date hereof, on the terms and conditions hereinafter set forth.

                                   AGREEMENT

                 In consideration of the foregoing and the mutual covenants and
agreements set forth herein, Sovereign and ML, intending to be legally bound
hereby, agree:

                 1.       Grant of Option.  ML hereby grants to Sovereign, on
the terms and conditions set forth herein, the option to purchase (the
"Option") up to 2,361,245 shares of Common Stock of ML (as adjusted as set
forth herein, the "Option Shares") at a price per share (as adjusted as set
forth herein, the "Option Price") equal to $21.875, provided, however, that in
no event shall the number of Option Shares for which the Option is exercisable
exceed 19.9% of the issued and outstanding shares of ML Common Stock without
giving effect to any shares subject to or issued pursuant to the Option.

                 2.       Exercise of Option.

                          (a)     Provided that (i) Sovereign shall not be, on
the date of exercise, in material breach of the agreements or covenants
contained in the Agreement or this Stock Option Agreement, and (ii) no
preliminary or permanent injunction or other order against the delivery of
shares covered by the Option issued by any court of competent jurisdiction in
the United States shall be in effect on the date of exercise, upon or after the
occurrence of a Triggering Event (as such term is hereinafter defined)
Sovereign may exercise the Option, in whole or in part, at any time
<PAGE>   80
or one or more times, from time to time; provided that the Option shall
terminate and be of no further force and effect upon the earliest to occur of
(A) the Effective Date of the Merger, as provided in the Agreement, (B)
termination of the Agreement in accordance with the terms thereof prior to the
occurrence of a Triggering Event or a Preliminary Triggering Event, other than
a termination of the Agreement pursuant to Section 6.01(d), unless in the case
of termination by ML pursuant to Section 6.01(d), such termination is as a
result of a willful breach of the Agreement by Sovereign (a termination
pursuant to Section 6.01(d), except a termination by ML as a result of a
willful breach by Sovereign, being referred to herein as a "Default
Termination"), (C) 18 months after the termination of the Agreement by
Sovereign or ML pursuant to a Default Termination, and (D) 18 months after
termination of the Agreement (other than pursuant to a Default Termination)
following the occurrence of a Triggering Event or a Preliminary Triggering
Event; and provided, further, that any purchase of shares upon exercise of the
Option shall be subject to compliance with applicable securities and banking
laws.  The rights set forth in Section 3 hereof shall terminate when the right
to exercise the Option terminates (other than as a result of a complete
exercise of the Option) as set forth above.

                          (b)     As used herein, the term "Triggering Event"
means the occurrence of any of the following events:

                                  (i)  a person or group (as such terms are
         defined in the Securities Exchange Act of 1934, as amended (the
         "Exchange Act"), and the rules and regulations thereunder), other than
         Sovereign or an affiliate of Sovereign, acquires beneficial ownership
         (within the meaning of Rule 13d-3 under the Exchange Act) of 25% or
         more of the then outstanding shares of Common Stock (excluding any
         shares eligible to be reported on Schedule 13G of the Securities and
         Exchange Commission); or

                                  (ii)  a person or group, other than Sovereign
         or an affiliate of Sovereign, enters into an agreement or letter of
         intent or memorandum of understanding with ML pursuant to which such
         person or group or any affiliate of such person or group would (i)
         merge or consolidate, or enter into any similar transaction, with ML,
         (ii) acquire all or substantially all of the assets or liabilities of
         ML or all or substantially all of the assets or liabilities of Main
         Line Bank (or any successor subsidiary), the wholly-owned subsidiary
         of ML ("ML Bank"), or (iii) acquire beneficial ownership of securities
         representing, or the right to acquire beneficial ownership or to vote
         securities representing, 25% or more of the then outstanding shares of
         Common Stock (excluding any shares eligible to be reported on Schedule
         13G of the Securities and Exchange Commission) or the then outstanding
         shares of common stock of ML Bank, or ML shall





                                       2
<PAGE>   81
         have authorized, recommended or publicly proposed, or publicly
         announced an intention to authorize, recommend or propose, such an
         agreement or letter of intent or memorandum of understanding.

                          (c)     As used herein, the term "Preliminary
Triggering Event" means the occurrence of any of the following events:

                                  (i)  a person or group (as such terms are
         defined in the Exchange Act and the rules and regulations thereunder),
         other than Sovereign or an affiliate of Sovereign, acquires beneficial
         ownership (within the meaning of Rule 13d-3 under the Exchange Act) of
         10% or more of the then outstanding shares of Common Stock (excluding
         any shares eligible to be reported on Schedule 13G of the Securities
         and Exchange Commission);

                                  (ii)  a person or group, other than Sovereign
         or an affiliate of Sovereign, publicly announces a bona fide proposal
         (including a written communication that is or becomes the subject of
         public disclosure) for (i) any merger, consolidation or acquisition of
         all or substantially all the assets or liabilities of ML or all or
         substantially all the assets or liabilities of ML Bank, or any other
         business combination involving ML or ML Bank, or (ii) a transaction
         involving the transfer of beneficial ownership of securities
         representing, or the right to acquire beneficial ownership or to vote
         securities representing, 10% or more of the then outstanding shares of
         Common Stock or the then outstanding shares of Common Stock of ML Bank
         (collectively, a "Proposal"), and thereafter, if such Proposal has not
         been Publicly Withdrawn (as such term is hereinafter defined) at least
         30 days prior to the meeting of shareholders of ML called to vote on
         the Merger, ML's shareholders fail to approve the Merger by the vote
         required by applicable law at the meeting of shareholders called for
         such purpose or such meeting has been cancelled; or

                                  (iii)  the Board of Directors of ML shall (A)
         fail to recommend the Merger, (B) recommend an Acquisition Transaction
         or (C)  have withdrawn or modified in a manner adverse to Sovereign
         the recommendation of the Board of Directors of ML with respect to the
         Agreement and thereafter ML's shareholders fail to approve the Merger
         by the vote required by law at the meeting of shareholders called for
         such purpose or such meeting is not scheduled or is cancelled; or

                                  (iv)  a person or group, other than Sovereign
         or an affiliate of Sovereign, makes a bona fide Proposal and
         thereafter, but before such Proposal has been Publicly Withdrawn, ML
         shall have breached any representation,





                                       3
<PAGE>   82
         warranty, covenant or obligation contained in the Agreement and such
         breach would entitle Sovereign to terminate the Agreement under
         Section 6.01(d) thereof (without regard to the cure period provided
         for therein unless such cure is promptly effected without jeopardizing
         consummation of the Merger pursuant to the Agreement).

If more than one of the transactions giving rise to a Triggering Event or a
Preliminary Triggering Event under this Section 2 is undertaken or effected,
then all such transactions shall give rise only to one Triggering Event or
Preliminary Triggering Event, as applicable, which Triggering Event or
Preliminary Triggering Event shall be deemed continuing for all purposes
hereunder until all such transactions are abandoned.

                 "Publicly Withdrawn" for purposes of this Section 2 shall mean
an unconditional bona fide withdrawal of the Proposal coupled with a public
announcement of no further interest in pursuing such Proposal or in acquiring
any controlling influence over ML or in soliciting or inducing any other person
(other than Sovereign or an affiliate of Sovereign) to do so.

                 Notwithstanding the foregoing, the obligation of ML to issue
Option Shares upon exercise of the Option shall be deferred (but shall not
terminate):  (i) until the receipt of all required governmental or regulatory
approvals or consents necessary for ML to issue the Option Shares or Sovereign
to exercise the Option, or until the expiration or termination of any waiting
period required by law, or (ii) so long as any injunction or other order,
decree or ruling issued by any federal or state court of competent jurisdiction
is in effect which prohibits the sale or delivery of the Option Shares, and, in
each case, notwithstanding any provision to the contrary set forth herein, the
Option shall not expire or otherwise terminate.

                 ML shall notify Sovereign promptly in writing of the
occurrence of any Triggering Event known to it, it being understood that the
giving of such notice by ML shall not be a condition to the right of Sovereign
to exercise the Option.  ML will not take any action which would have the
effect of preventing or disabling ML from delivering the Option Shares to
Sovereign upon exercise of the Option or otherwise performing its obligations
under this Stock Option Agreement, except to the extent required by applicable
securities and banking laws and regulations.  In the event Sovereign wishes to
exercise the Option, Sovereign shall send a written notice to ML (the date of
which is hereinafter referred to as the "Notice Date") specifying the total
number of Option Shares it wishes to purchase and a place and date between two
and  ten business days inclusive from the Notice Date for the closing of such a
purchase (a "Closing"); provided, however, that a Closing shall not occur prior
to two days after the later of receipt of any





                                       4
<PAGE>   83
necessary regulatory approvals or the expiration of any legally required notice
or waiting period, if any.

                 3.       Repurchase of Option by ML.

                          (a)     Subject to the last sentence of Section 2(a),
at the request of Sovereign at any time commencing upon the first occurrence of
a Repurchase Event (as defined in Section 3(d)) and ending 18 months
immediately thereafter, ML shall repurchase from Sovereign (x) the Option and
(y) all shares of Common Stock purchased by Sovereign pursuant hereto with
respect to which Sovereign then has beneficial ownership.  The date on which
Sovereign exercises its rights under this Section 3 is referred to as the
"Request Date."  Such repurchase shall be at an aggregate price (the "Section 3
Repurchase Consideration") equal to the sum of:

                                  (i)  the aggregate Purchase Price paid by
         Sovereign for any shares of Common Stock acquired pursuant to the
         Option with respect to which Sovereign then has beneficial ownership;

                                  (ii)  the excess, if any, of (x) the
         Applicable Price (as defined below) for each share of Common Stock
         over (y) the Option Price (subject to adjustment pursuant to Section
         6), multiplied by the number of shares of Common Stock with respect to
         which the Option has not been exercised; and

                                  (iii)  the excess, if any, of the Applicable
         Price over the Option Price (subject to adjustment pursuant to Section
         6) paid (or, in the case of Option Shares with respect to which the
         Option has been exercised, but the Closing has not occurred, payable)
         by Sovereign for each share of Common Stock with respect to which the
         Option has been exercised and with respect to which Sovereign then has
         beneficial ownership, multiplied by the number of such shares.

                          (b)     If Sovereign exercises it rights under this
Section 3, ML shall, within ten (10) business days after the Request Date, pay
the Section 3 Repurchase Consideration to Sovereign in immediately available
funds, and contemporaneously with such payment, Sovereign shall surrender to ML
the Option and the certificate evidencing the shares of Common Stock purchased
thereunder with respect to which Sovereign then has beneficial ownership, and
Sovereign shall warrant that it has sole record and beneficial ownership of
such shares, and that the same are then free and clear of all liens, claims,
charges and encumbrances of any kind whatsoever.  Notwithstanding the
foregoing, to the extent that prior notification to or approval of any banking
agency or department of any federal or state government, including without
limitation the OTS, the FDIC, or the respective staffs thereof (the "Regulatory
Authority"), is required in connection with the payment





                                       5
<PAGE>   84
of all or any portion of the Section 3 Repurchase Consideration, Sovereign
shall have the ongoing option to revoke its request for repurchase pursuant to
Section 3, in whole or in part, or to require that ML deliver from time to time
that portion of the Section 3 Repurchase Consideration that it is not then so
prohibited from paying and promptly file the required notice or application for
approval and expeditiously process the same (and each party shall cooperate
with the other in the filing of any such notice or application and the
obtaining of any such approval), in which case the ten (10) business day period
of time that would otherwise run pursuant to the preceding sentence for the
payment of the portion of the Section 3 Repurchase Consideration shall run
instead from the date on which, as the case may be, any required notification
period has expired or been terminated or such approval has been obtained and,
in either event, any requisite waiting period shall have passed.  If any
Regulatory Authority disapproves of any part of ML's proposed repurchase
pursuant to this Section 3, ML shall promptly give notice of such fact to
Sovereign.  If any Regulatory Authority prohibits the repurchase pursuant to
this Section 3, ML shall promptly give notice of such fact to Sovereign.  If
any Regulatory Authority prohibits the repurchase in part but not in whole,
then Sovereign shall have the right (i) to revoke the repurchase request or
(ii) to the extent permitted by such Regulatory Authority, determine whether
the repurchase should apply to the Option and/or Option Shares and to what
extent to each, and Sovereign shall thereupon have the right to exercise the
Option as to the number of Option Shares for which the Option was exercisable
at the Request Date less the sum of the number of shares covered by the Option
in respect of which payment has been made pursuant to Section 3(a)(ii) and the
number of shares covered by the portion of the Option (if any) that has been
repurchased.  Sovereign shall notify ML of its determination under the
preceding sentence within five (5) business days of receipt of notice of
disapproval of the repurchase.

                          (c)     For purposes of this Agreement, the
"Applicable Price" means the highest of (i) the highest price per share of
Common Stock paid for any such share by the person or groups described in
Section 3(d)(i), (ii) the price per share of Common Stock received by a holder
of Common Stock in connection with any merger or other business combination
transaction described in Section 3(d)(ii), (iii) or (iv), or (iii) the highest
closing sales price per share of Common Stock quoted on the Nasdaq Stock Market
during the 40 business days preceding the Request Date; provided, however, that
in the event of a sale of less than all of ML's assets, the Applicable Price
shall be the sum of the price paid in such sale for such assets and the current
market value of the remaining assets of ML as determined by a
nationally-recognized investment banking firm selected by Sovereign, divided by
the number of shares of Common Stock outstanding at the time of such sale.  If
the consideration to be offered, paid or received pursuant to either of the
foregoing clauses (i) or (ii) shall be





                                       6
<PAGE>   85
other than in cash, the value of such consideration shall be determined in good
faith by an independent nationally-recognized investment banking firm selected
by Sovereign and reasonably acceptable to ML, which determination shall be
conclusive for all purposes of this Agreement.

                          (d)     As used herein, a Repurchase Event shall
occur if (i) any person or group (as such terms are defined in the Exchange Act
and the rules and regulations thereunder), other than Sovereign or an affiliate
of Sovereign, acquires beneficial ownership (within the meaning of Rule 13d-3
under the Exchange Act) of, or the right to acquire beneficial ownership of,
25% or more of the then-outstanding shares of Common Stock, (ii) ML shall have
merged or consolidated with any person, other than Sovereign or an affiliate of
Sovereign, and shall not be the surviving or continuing corporation of such
merger or consolidation, (iii) any person, other than Sovereign or an affiliate
of Sovereign, shall have merged into ML and ML shall be the surviving
corporation, but, in connection with such merger, the then-outstanding shares
of Common Stock have been changed into or exchanged for stock or other
securities of ML or any other person or cash or any other property or the
outstanding shares of Common Stock immediately prior to such merger shall after
such merger represent less than 50% of the outstanding shares and share
equivalents of the surviving corporation or (iv) ML shall have sold or
otherwise transferred more than 25% of its consolidated assets to any person,
other than Sovereign or an affiliate of Sovereign.

                 4.       Payment and Delivery of Certificates.  At any Closing
hereunder, (a) Sovereign will make payment to ML of the aggregate price for the
Option Shares so purchased by wire transfer of immediately available funds to
an account designated by ML, (b) ML will deliver to Sovereign a stock
certificate or certificates representing the number of Option Shares so
purchased, registered in the name of Sovereign or its designee, in such
denominations as were specified by Sovereign in its notice of exercise, and (c)
Sovereign will pay any transfer or other taxes required by reason of the
issuance of the Option Shares so purchased.

                 A legend will be placed on each stock certificate evidencing
Option Shares issued pursuant to this Stock Option Agreement, which legend will
read substantially as follows:

                          "The shares of stock evidenced by this certificate
         have not been the subject of a registration statement filed under the
         Securities Act of 1933, as amended (the "Act"), and declared effective
         by the Securities and Exchange Commission.  These shares may not be
         sold, transferred or otherwise disposed of prior to such time unless
         ML Bancorp, Inc. receives an opinion of counsel acceptable to it
         stating that an exemption from





                                       7
<PAGE>   86
         the registration provisions of the Act is available for such
         transfer."

                 5.       Registration Rights.  Upon or after the occurrence of
a Triggering Event and upon receipt of a written request from Sovereign, ML
shall prepare and file as soon as practicable a registration statement under
the Securities Act of 1933 (the "Securities Act") with the Securities and
Exchange Commission covering the Option and such number of Option Shares as
Sovereign shall specify in its request, and ML shall use its best efforts to
cause such registration statement to be declared effective in order to permit
the sale or other disposition of the Option and the Option Shares, provided
that Sovereign shall in no event have the right to have more than one such
registration statement become effective, and provided further that ML shall not
be required to prepare and file any such registration statement in connection
with any proposed sale with respect to which counsel to ML delivers to ML and
to Sovereign its opinion to the effect that no such filing is required under
applicable laws and regulations with respect to such sale or disposition;
provided further, however, that ML may delay any registration of Option Shares
above for a period not exceeding 90 days in the event that ML shall in good
faith determine that any such registration would adversely affect an offering
or contemplated offering of securities by ML.  Sovereign shall provide all
information reasonably requested by ML for inclusion in any registration
statement to be filed hereunder.  In connection with such filing, ML shall use
its reasonable best efforts to cause to be delivered to Sovereign such
certificates, opinions, accountant's letters and other documents as Sovereign
shall reasonably request and as are customarily provided in connection with
registration of securities under the Securities Act.  ML shall provide to
Sovereign such number of copies of the preliminary prospectus and final
prospectus and any amendments and supplements thereto as Sovereign may
reasonably request.

                 All reasonable expenses incurred by ML in complying with the
provisions of this Section 5, including, without limitation, all registration
and filing fees, reasonable printing expenses, reasonable fees and
disbursements of counsel for ML and blue sky fees and expenses, shall be paid
by ML.  Underwriting discounts and  commissions to brokers and dealers relating
to the Option Shares, fees and disbursements of counsel to Sovereign and any
other expenses incurred by Sovereign in connection with such filing shall be
borne by Sovereign.  In connection with such filing, ML shall indemnify and
hold harmless Sovereign against any losses, claims, damages or liabilities,
joint or several, to which Sovereign may become subject, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise
out of or are based upon any untrue statement or alleged untrue statement of
any material fact contained in any preliminary or final registration statement
or any amendment or supplement thereto, or arise out of or are based upon the
omission or alleged omission to state therein





                                       8
<PAGE>   87
a material fact required to be stated therein or necessary to make the
statements therein not misleading; and ML will reimburse Sovereign for any
legal or other expense reasonably incurred by Sovereign in connection with
investigating or defending any such loss, claim, damage, liability or action;
provided, however, that ML will not be liable in any case to the extent that
any such loss, claim, damage or liability arises out of or is based upon an
untrue statement or alleged untrue statement or omission or alleged omission
made in such preliminary or final registration statement or such amendment or
supplement thereto in reliance upon and in conformity with written information
furnished by or on behalf of Sovereign specifically for use in the preparation
thereof.  Sovereign will indemnify and hold harmless ML to the same extent as
set forth in the immediately preceding sentence but only with reference to
written information furnished by or on behalf of Sovereign for use in the
preparation of such preliminary or final registration statement or such
amendment or supplement thereto; and Sovereign will reimburse ML for any legal
or other expense reasonably incurred by ML in connection with investigating or
defending any such loss, claim, damage, liability or action.  Notwithstanding
anything to the contrary contained herein, no indemnifying party shall be
liable for any settlement effected without its prior written consent.

                 6.       Adjustment Upon Changes in Capitalization.  In the
event of any change in the Common Stock by reason of stock dividends,
split-ups, recapitalizations, combinations, conversions, divisions, exchanges
of shares or the like, then the number and kind of Option Shares and the Option
Price shall be appropriately adjusted.

                 7.       Filings and Consents.  Each of Sovereign and ML will
use its reasonable best efforts to make all filings with, and to obtain
consents of, all third parties and governmental authorities necessary to the
consummation of the transactions contemplated by this Stock Option Agreement.
Within 10 days from the date hereof, Sovereign shall file a report of
beneficial ownership on Form 13D with the Securities and Exchange Commission
under the Exchange Act which discloses the rights of Sovereign hereunder.

                 8.       Representations and Warranties of ML.  ML hereby
represents and warrants to Sovereign as follows:

                          (a)     Due Authorization.  ML has full corporate
power and authority to execute, deliver and perform this Stock Option Agreement
and all corporate action necessary for execution, delivery and performance of
this Stock Option Agreement has been duly taken by ML.  This Stock Option
Agreement constitutes a legal, valid and binding obligation of ML, enforceable
against ML in accordance with its terms (except as may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and
similar laws of general applicability





                                       9
<PAGE>   88
relating to or affecting creditors' rights or by general equity principles).

                          (b)     Authorized Shares.  ML has taken all
necessary corporate action to authorize and reserve for issuance all shares of
Common Stock that may be issued pursuant to any exercise of the Option.

                 9.       Representations and Warranties of Sovereign.
Sovereign hereby represents and warrants to ML that Sovereign has full
corporate power and authority to execute, deliver and perform this Stock Option
Agreement and all corporate action necessary for execution, delivery and
performance of this Stock Option Agreement has been duly taken by Sovereign.
This Stock Option  Agreement constitutes a legal, valid and binding obligation
of Sovereign, enforceable against Sovereign in accordance with its terms
(except as may be limited by applicable bankruptcy, insolvency, reorganization,
moratorium, fraudulent transfer and similar laws of general applicability
relating to or affecting creditors' rights or by general equity principles).

                 10.      Specific Performance.  The parties hereto acknowledge
that damages would be an inadequate remedy for a breach of this Stock Option
Agreement and that the obligations of the parties hereto shall be specifically
enforceable.

                 11.      Entire Agreement.  This Stock Option Agreement and
the Agreement constitute the entire agreement between the parties with respect
to the subject matter hereof and supersede all other prior agreements and
understandings, both written and oral, among the parties or any of them with
respect to the subject matter hereof.

                 12.      Assignment or Transfer.  Sovereign may not sell,
assign or otherwise transfer its rights and obligations hereunder, in whole or
in part, to any person or group of persons other than to a subsidiary of
Sovereign.  Sovereign represents that it is acquiring the Option for
Sovereign's own account and not with a view to, or for sale in connection with,
any distribution of the Option or the Option Shares.  Sovereign is aware that
neither the Option nor the Option Shares is the subject of a registration

                    FORM OF OPINION OF COUNSEL TO SOVEREIGN


                 ML shall have received from counsel to Sovereign, an opinion,
dated as of the Closing Date, substantially to the effect that, subject to
normal exceptions and qualifications:

                 (a)      Sovereign and Sovereign Bank have full corporate
power to carry out the transactions contemplated in the Agreement and the Bank
Plan of Merger, respectively.  The execution and delivery of the Agreement and
the Bank Plan of Merger and the consummation of the transactions contemplated
thereunder have been duly and validly authorized by all necessary corporate
action on the part of Sovereign and Sovereign Bank, and the Agreement and the
Plan constitute valid and legally binding obligations of Sovereign and
Sovereign Bank, respectively, except as may be limited by (i) bankruptcy,
insolvency, reorganization, moratorium, receivership, conservatorship, and
other laws now or hereafter in effect relating to or affecting the enforcement
of creditors' rights generally or the rights of creditors of federal savings
institutions or their holding companies, (ii) general equitable principles, and
(iii) laws relating to the safety and soundness of insured depository
institutions, and except that no opinion need be rendered as to the effect or
availability of equitable remedies or injunctive relief (regardless of whether
such enforceability is considered in a proceeding in equity or at law).
Subject to satisfaction of the conditions set forth in the Agreement, neither
the transactions contemplated in the Agreement or the Plan, nor compliance by
Sovereign and Sovereign Bank with any of the respective provisions thereof,
will (i) conflict with or result in a breach or default under (A) the articles
of incorporation or bylaws of Sovereign or the charter or bylaws of Sovereign
Bank, or, (B) to the knowledge of such counsel, any note, bond, mortgage,
indenture, license, agreement or other material instrument or obligation to
which Sovereign or Sovereign Bank is a party; or (ii) based on certificates of
officers and without independent verification, to the knowledge of such
counsel, result in the creation or imposition of any material lien or
encumbrance upon the property of Sovereign or Sovereign Bank, except such
material lien, instrument or obligation that has been disclosed pursuant to the
Agreement or the Plan; or (iii) violate in any material respect any order,
writ, injunction or decree known to such counsel, or any federal or
Pennsylvania statute, rule or regulation applicable to Sovereign or Sovereign
Bank.

                 (b)      Sovereign Bank is a validly existing
federally-chartered savings bank organized under the laws of the United States
of America.  The deposits of Sovereign Bank are insured to the maximum extent
provided by law by the Federal Deposit Insurance Corporation.
<PAGE>   99
                 (c)      There is, to the knowledge of such counsel, no legal,
administrative, arbitration or governmental proceeding or investigation pending
or threatened to which Sovereign or Sovereign Bank is a party which would, if
determined adversely to Sovereign or Sovereign Bank, have a material adverse
effect on the financial condition or results of operation of Sovereign and
Sovereign Bank taken as a whole, or which presents a claim to restrain or
prohibit the transactions contemplated by the Agreement and the Plan,
respectively.

                 (d)      No consent, approval, authorization or order of any
federal or state court or federal or state governmental agency or body, or to
such counsel's knowledge is required for the consummation by Sovereign or
Sovereign Bank of the transactions contemplated by the Agreement and the Plan,
except for such consents, approvals, authorizations or orders as have been
obtained or which would not have a Material Adverse Effect upon Sovereign upon
consummation of the Merger.

                 (e)      Upon the filing and effectiveness of the Articles of
Merger with the PDS and Articles of Combination with the OTS in accordance with
the Agreement and the Plan, the mergers of Sovereign and ML and of Sovereign
Bank and ML Bank contemplated by the Agreement and the Plan, respectively, will
have been effected in compliance with all applicable federal and Pennsylvania
laws and regulations in all material respects.

                 (f)      The shares of Sovereign Common Stock to be issued in
connection with the merger of ML and Sovereign contemplated by the Agreement
have been duly authorized and will, when issued in accordance with the terms of
the Agreement, be validly issued, fully paid and nonassessable, free and clear
of any mortgage, pledge, lien, encumbrance or claim (legal or equitable).

                 (g)      In addition to the foregoing opinions, counsel shall
state that the sole basis of such counsel's participation in conferences with
officers and employees of Sovereign in connection with the Proxy
Statement/Prospectus, and without other independent investigation or inquiry,
such counsel has no reason to believe that the Proxy Statement/Prospectus,
including any amendments or supplements thereto (except for the financial
information, financial statements, notes to financial statements, financial
schedules and other financial or statistical data and stock valuation
information contained or incorporated by reference therein and except for any
information supplied by ML or ML Bank for inclusion therein, as to which
counsel need express no belief), as of the date of mailing thereof, contained
any untrue statement of a material fact with respect to Sovereign or omitted to
state any material fact with respect to Sovereign necessary to make any
statement therein with respect to Sovereign, in light of the circumstances
under which it was made, not misleading.  Counsel may state in connection with
the foregoing, that such counsel has not





                                       2
<PAGE>   100
independently verified and does not assume the responsibility for the accuracy,
completeness or fairness of any information or statements  contained in the
Proxy Statement/Prospectus, except with respect to identified statements of law
or regulations or legal conclusions relating to Sovereign or the transactions
contemplated in the Agreement and the Plan and that it is relying as to
materiality as to factual matters on certificates of officers and
representatives of the parties to the Agreement and other factual
representations by ML and Main Line Bank.

                 Such counsel's opinion shall be limited to matters governed by
federal banking and securities laws and by the BCL.

                      FORM OF TAX OPINION OF STEVENS & LEE

         Sovereign and ML shall have received an opinion of Stevens & Lee
substantially to the effect that, under the provisions of the IRC:

         1.      The transfer by ML of all of its assets to Sovereign in
exchange for Sovereign Common Stock (including fractional share interests) and
the assumption by Sovereign of all of ML's liabilities will constitute a
reorganization within the meaning of Section 368(a)(1)(A) of the IRC.

         2.      ML and Sovereign will each be "a party to a reorganization"
within the meaning of Section 368(b) of the IRC.

         3.      Neither ML nor Sovereign will recognize any gain or loss upon
the transfer of ML's assets to Sovereign in exchange solely for Sovereign
Common Stock (including fractional share interests) and the assumption by
Sovereign of the liabilities of ML.

         4.      The basis of the ML assets in the hands of Sovereign will be
the same as the basis of such assets in the hands of ML immediately prior to
the Merger.

         5.      The holding period of the assets of ML to be received by
Sovereign will include the period during which the assets were held by ML.

         6.      No gain or loss will be recognized by the shareholders of ML
on the receipt of Sovereign Common Stock (including fractional share interests)
solely in exchange for their shares of ML Common Stock.

         7.      The basis of the Sovereign Common Stock (including fractional
share interests) to be received by the ML shareholders in the Merger will be
the same as the basis of the ML Common Stock surrendered in exchange therefor.

         8.      The holding period of the Sovereign Common Stock (including
fractional share interests) to be received by the ML shareholders in the Merger
will include the period during which the ML shareholders held their ML Common
Stock, provided the shares of ML Common Stock are held as a capital asset on
the Effective Date.

         9.      The payment of cash in lieu of fractional share interests of
Sovereign Common Stock will be treated as if the fractional share interests
were distributed as part of the Merger and then redeemed by Sovereign.  Such
cash payments will be treated as having been received as distribution in full
payment in exchange
<PAGE>   102
for the fractional share interests redeemed, as provided in Section 302(a) of
the IRC.

         10.     The Sovereign Stock Purchase Rights transferred with the
shares of Sovereign Common Stock will not constitute "other property" within
the meaning of Section 356(a)(1)(B) of the IRC.

         11.     As provided in Section 381(c)(2) of the IRC and related
Treasury regulations, Sovereign will succeed to and take into account the
earnings and profits, or deficit in earnings and profits, of ML as of the
Effective Date.  Any deficit in the earnings and profits of Sovereign or ML
will be used only to offset the earnings and profits accumulated after the
Merger.

         12.     Pursuant to Section 381(a) of the IRC and related Treasury
regulations, Sovereign will succeed to and take into account the items of ML
described in Section 381(c) of the IRC.  Such items will be taken into account
by Sovereign subject to the conditions and limitations of Sections 381, 382,
383, and 384 of the IRC and the Treasury regulations thereunder.

         13.     The Bank Merger will constitute a reorganization within the
meaning of Section 368(a)(1)(A) of the IRC.

         14.     ML Bank and Sovereign Bank will each be "a party to a
reorganization" within the meaning of Section 368(b) of the IRC.

         15.     Neither ML Bank nor Sovereign Bank will recognize any gain or
loss upon the transfer of ML Bank's assets to Sovereign Bank in constructive
exchange solely for Sovereign Bank common stock and the assumption by Sovereign
Bank of the liabilities of ML Bank.

         16.     The basis of the ML Bank assets in the hands of Sovereign Bank
will be the same as the basis of such assets in the hands of ML Bank
immediately prior to the Bank Merger.

         17.     The holding period of the ML Bank assets in the hands of
Sovereign Bank will include the period during which such assets were held by ML
Bank.

         18.     No gain or loss will be recognized by Sovereign, as the
shareholder of ML Bank, upon the constructive receipt of shares of Sovereign
Bank common stock in exchange for the ML Bank common stock surrendered in
exchange therefor in the Bank Merger.

         19.     The basis of the Sovereign Bank common stock to be held by
Sovereign after the Bank Merger will equal the basis of such stock immediately
before the Bank Merger, increased by the basis of the ML Bank common stock
surrendered in the constructive exchange.

Treasury regulations, Sovereign Bank will succeed to and take into account the

                              SOVEREIGN TO ACQUIRE
                                ML BANCORP, INC.

         WYOMISSING, PA., Sovereign Bancorp, Inc. ("Sovereign")
(NASDAQ/NMS:SVRN), parent company of Sovereign Bank, and ML Bancorp, Inc. ("ML
Bancorp") (NASDAQ/:MLBC), parent company of Main Line Bank, announced today the
execution of a Definitive Agreement ("Agreement") for Sovereign to acquire ML
Bancorp.  ML Bancorp is a $2.2 billion bank holding company whose principal
operating subsidiary operates 29 branches located in the suburbs of
Philadelphia, Pennsylvania.

         The terms of the Agreement call for Sovereign to exchange 1.67 shares
of Sovereign common stock for each outstanding share of ML Bancorp common stock
or a total consideration of approximately $345 million in Sovereign common
stock.  The exchange ratio will stay fixed at 1.67 shares of Sovereign common
stock per ML Bancorp share if Sovereign's average stock price remains between
$13.80 and $18.67 per share (collectively, the "Collars") during a 20-day
pricing period as set forth in the Agreement.  If Sovereign's average stock
price is outside the lower or upper Collars then the price is fixed for ML
Bancorp's shareholders at $23.05 and $31.18 per share, respectively, subject to
adjustment under certain conditions.  The pricing reflects 202% of ML Bancorp's
stated book value, 215% of ML Bancorp tangible book value and 17.4 times ML
Bancorp projected 1998 earnings.

         ML Bancorp operates a solid mortgage banking operation with a $4.4
billion loan servicing portfolio for others and $500 million in 1996 loan
originations, in addition to an extensive community banking franchise.  In
addition, ML Bancorp's asset quality philosophy mirrors Sovereign's focus on
this critical success factor.  ML Bancorp maintains superior asset quality with
a non-performing assets to total assets ratio of only 0.46%, a strong loan loss
reserve to total loans of 1.71%, and loan loss reserves to non-performing loans
of 193% at June 30, 1997.

         "The combination of these two institutions significantly enhances
Sovereign's franchise in the affluent and growing communities of the
Philadelphia suburbs, and is expected to be immediately accretive to
Sovereign's book value, tangible book value, and accretive to Sovereign's
earnings, within 12 months following the consummation of the transaction,"
<PAGE>   2
stated Jay S. Sidhu, Sovereign's President and Chief Executive Officer.  "This
transaction solidifies Sovereign's Pennsylvania, New Jersey, and Delaware
branch networks and creates a $2.4 billion deposit franchise in Pennsylvania
with strong core deposits.  Proforma for this acquisition, Sovereign will have
the #4 deposit market share in southeastern Pennsylvania," Sidhu continued.

         "Our strategic affiliation with Sovereign provides our shareholders
and customers with a unique opportunity to continue our vision of becoming a
significant financial services provider in Southeastern Pennsylvania, as well
as a significant contributor to Sovereign's franchise value and future earnings
growth," stated Dennis S. Marlo, ML Bancorp, Inc.'s President and Chief
Executive Officer.

         Upon completion of this transaction, Mr. Marlo will become a member of
Sovereign Bank's Board of Directors and the President of the division of
Sovereign Bank responsible for the Sovereign Bank's Pennsylvania and Delaware
branch network.

         Proforma for the ML Bancorp acquisition and other pending
transactions, Sovereign will have assets totalling $17.0 billion, deposits
totaling $8.6 billion and operate over 170 Community banking offices throughout
the tri-state network.  With a pro forma market capitalization in excess of
$2.0 billion, Sovereign will become the 6th largest thrift holding company in
the country.

         "The addition of this 29 branch network is a perfect fit with
Sovereign's Pennsylvania branch network," commented Sovereign's Chairman,
Richard E. Mohn.  "ML Bancorp is a natural fill-in to Sovereign's existing
franchise and will provide Sovereign unique opportunities in an extremely
desirable market," Mohn continued.

         In connection with the execution of the Agreement, ML Bancorp granted
a stock option to Sovereign to purchase, under certain conditions, up to 19.9%
of ML Bancorp's outstanding shares.

         ML Bancorp has the right to terminate the Agreement if the average
stock price of Sovereign (as defined in the Agreement) falls below $12.18 and
Sovereign's decline in value is 10% greater than the percentage decline of a
group of similar financial institutions.

         The merger is subject to approval of various regulatory agencies and
of both ML Bancorp and Sovereign shareholders.  Sovereign anticipates that the
transaction will close in the first quarter of 1998 and will be accounted for
as a pooling of interests.  Sovereign also anticipates recording a one-time
after tax merger-related charge of $12.4 million at the closing of the
transaction.

         On July 2, 1997, Sovereign announced the signing of a definitive
agreement to acquire the Automobile Finance Division ("the Division") of Fleet
Financial Group, Inc.  The Division consists of approximately $2.0 billion of
indirect auto loans, dealer floor plan





                                      -2-
<PAGE>   3
plans, and loans to automobile leasing companies.  The Division has business
relationships with over 2,000 automotive dealerships and serves approximately
225,000 customers through New Jersey, New York, and New England.

         On August 31, 1997, Sovereign closed its previously announced
acquisition of Bankers Corp., a $2.6 billion bank holding company headquartered
in Perth Amboy, New Jersey.  Sovereign is a pro forma $17.2 billion bank
holding company with over 170 community banking offices serving eastern
Pennsylvania, northern Delaware and New Jersey. The fourth largest bank
headquartered in Pennsylvania, Sovereign's closing price of its common stock on
Thursday, September 18, 1997 was $16.4375 per share and its preferred stock
closed at $99.75 per share.
