     Peoples Subsidiary) shall, on the Effective Date, by reason of the Merger
     and without any action on the part of the holder thereof, be converted into
     and become a right to receive .80 fully paid and nonassessable shares of
     Sovereign Common Stock, and the corresponding percentage of Sovereign Stock
     Purchase Rights pursuant to the Sovereign Rights Agreement.

               (B) Each share of Peoples Common Stock owned by Sovereign or a
     Sovereign Subsidiary on the Effective Date, if any, shall be cancelled.

               (C) Each share of Peoples Common Stock issued and held in the

     in exchange therefor.

               (D) No fraction of a whole share of Sovereign Common Stock and no
     scrip or certificates therefor shall be issued in connection with the
     Merger.  Any former holder of Peoples Common Stock who would otherwise be

                                       9

 
     entitled to receive a fraction of a share of Sovereign Common Stock shall
     receive, in lieu thereof, cash in an amount equal to such fraction of a
     share multiplied by the Sovereign Market Price determined as of the
     Effective Date.

          (f)  Stock Options.
               ------------- 

               (i)  On the Effective Date, each option to acquire Peoples Common
     Stock which is then outstanding ("Peoples Option"), whether or not
     exercisable, shall cease to represent a right to acquire shares of Peoples
     Common Stock and shall be converted automatically into an option to
     purchase shares of Sovereign Common Stock and the corresponding number of
     Sovereign Stock Purchase Rights, and Sovereign shall assume each Peoples
     Option, in accordance with the terms of the applicable Peoples Stock Option
     Plan and stock option agreement by which it is evidenced, except that from
     and after the Effective Date, (i) Sovereign and its Board of Directors or a
     duly authorized committee thereof shall be substituted for Peoples and
     Peoples' Board of Directors or duly authorized committee thereof
     administering such Peoples Stock Option Plan, (ii) each Peoples Option
     assumed by Sovereign may be exercised solely for shares of Sovereign Common
     Stock and Sovereign Stock Purchase Rights, (iii) the number of shares of
     Sovereign Common Stock subject to such Peoples Option shall be equal to the
     number of shares of Peoples Common Stock subject to such Peoples Option
     immediately prior to the Effective Date multiplied by the Applicable
     Exchange Ratio, provided that any fractional shares of Sovereign Common
     Stock resulting from such multiplication shall be rounded down to the
     nearest share, and (iv) the per share exercise price under each such
     Peoples Option shall be adjusted by dividing the per share exercise price
     under each such Peoples Option by the Applicable Exchange Ratio, provided
     that such exercise price shall be rounded down to the nearest cent.
     Notwithstanding clauses (iii) and (iv) of the preceding sentence, each
     Peoples Option which is an "incentive stock option" shall be adjusted as
     required by Section 424 of the IRC, and the regulations promulgated
     thereunder, so as not to constitute a modification, extension or renewal of
     the option within the meaning of Section 424(h) of the IRC.  Sovereign and
     Peoples agree to take all necessary steps to effect the foregoing
     provisions of this Section 1.02(f).

               (ii)  Within 45 days after the Effective Date, Sovereign shall
     file a registration statement on Form S-8 (or any other successor or
     appropriate form) with respect to the shares of Sovereign Common Stock and
     Sovereign Stock Purchase Rights subject to the options referenced in this
     Section 1.02(f) and relating to the 1999 RRP (as defined in Section 4.11(a)
     (vii)), and shall use its reasonable best efforts to maintain the current
     status of

                                       10

 
     the prospectus or prospectuses contained therein for so long as such
     options remain outstanding.

          (g) Surrender and Exchange of Peoples Stock Certificates.
              ---------------------------------------------------- 

               (i)  Exchange of Certificates.  Each holder of shares of Peoples
                    ------------------------                                   
     Common Stock who surrenders to Sovereign (or its agent) the certificate or
     certificates representing such shares will be entitled to receive, as soon
     as practicable after the Effective Date, in exchange therefor a certificate
     or certificates for the number of whole shares of Sovereign Common Stock
     into which such holder's shares of Peoples Common Stock have been converted
     pursuant to the Merger, together with a check for cash in lieu of any
     fractional share in accordance with Section 1.02(e)(ii)(D) hereof.

               (ii)  Rights Evidenced by Certificates.  Each certificate for
                     --------------------------------                       
     shares of Sovereign Common Stock issued in exchange for certificates for
     Peoples 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
     Peoples Common Stock will, from and after the Effective Date, evidence
     solely the right to receive certificates for shares of Sovereign Common
     Stock pursuant to Section 1.02(g)(i) hereof and a check for cash in lieu of
     any fractional share in accordance with Section 1.02(e)(ii)(D) hereof.  If
     certificates for shares of Peoples Common Stock are exchanged for Sovereign
     Common Stock at a date following one or more record dates for the 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
     Peoples Common Stock in exchange for certificates for Sovereign Common
     Stock, Sovereign also shall pay any dividends to which such holder of
     Peoples Common Stock may be entitled as a result of the declaration of a
     dividend on the Peoples Common Stock by Peoples 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 Peoples Common
     Stock.

               Notwithstanding the foregoing, no party hereto will be liable to
     any holder of Peoples Common Stock for any amount paid in good faith to a
     public official or

                                       11

 
     agency pursuant to any applicable abandoned property, escheat or similar
     law.  Until such time as certificates for shares of Peoples Common Stock
     are surrendered by a Peoples shareholder to Sovereign for exchange,
     Sovereign shall have the right to withhold dividends or any other
     distributions on the shares of Sovereign Common Stock issuable to such
     shareholder.

               (iii)  Exchange Procedures.  Each certificate for shares of
                      -------------------                                 
     Peoples Common Stock delivered for exchange under this Section 1.02(g) must
     be endorsed in blank by the registered holder thereof or be accompanied by
     a power of attorney to transfer such shares endorsed in blank by such
     holder.  If more than one certificate is surrendered at one time and in one
     transmittal package for the same 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
     endorsed in blank, with signature(s) guaranteed, or otherwise in proper
     form for transfer, and the person to whom certificates for shares of
     Sovereign Common Stock is to be issued or to whom cash is to be paid shall
     pay any transfer or other taxes required by reason of such issuance or
     payment to a person other than the registered holder of the certificate for
     shares of Peoples Common Stock which are surrendered.  As promptly as
     reasonably practicable but in no event later than five (5) business days
     after the Effective Date, Sovereign shall send or cause to be sent to each
     shareholder of record of Peoples Common Stock transmittal materials for use
     in exchanging certificates representing Peoples 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 Peoples as promptly as reasonably
     practicable but in no event later than fifteen (15) business days following
     the receipt of certificates representing former shares of Peoples 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 Peoples
                     --------------------------------------------------------
     Certificates.  Upon the Effective Date, the stock transfer books for
     ------------                                                        
     Peoples Common Stock will be closed and no further transfers of shares of
     Peoples Common Stock will thereafter be made or recognized.  All

                                       12

 
     certificates for shares of Peoples Common Stock surrendered pursuant to
     this Section 1.02(g) will be cancelled by Sovereign.

          (h) Anti-Dilution Provisions.  If Sovereign shall, at any time before
              ------------------------                                         
the Effective Date, (A) issue a dividend in shares of Sovereign Common Stock,
(B) combine the outstanding shares of Sovereign Common Stock into a smaller
number of shares, (C) subdivide the outstanding shares of Sovereign Common
Stock, or (D) reclassify the shares of Sovereign Common Stock, then, in any such
event, the number of shares of Sovereign Common Stock to be delivered to Peoples
shareholders who are entitled to receive shares of Sovereign Common Stock in
exchange for shares of Peoples Common Stock shall be adjusted so that each
Peoples 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 immediately 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, the
Exchange Ratio determined pursuant to Sections 1.02(e)(ii) hereof shall be
adjusted upward by 7%).  In addition, in the event that, prior to the Effective
Date, Sovereign enters into an agreement pursuant to which shares of Sovereign
Common Stock would be converted into shares or other securities or obligations
of another corporation, proper provision shall be made in such agreement so that
each Peoples shareholder shall be entitled to receive such number of shares or
other securities or amount of obligations of such other corporation as such
shareholder would be entitled to receive if the Effective Date had occurred
immediately prior to the happening of such event.

          Section 1.03  The Bank Merger.  Sovereign and Peoples shall use their
                        ---------------                                        
best efforts to cause Trenton Savings to merge with and into Sovereign Bank,
with Sovereign Bank surviving such merger, as soon as practicable after the
Effective Date.  Concurrently with, or as soon as practicable after, the
execution and delivery of this Agreement, Sovereign shall cause Sovereign Bank,
and Peoples shall cause Trenton Savings, to execute and deliver the Bank Plan of
Merger attached hereto as Exhibit 3.

which would be applicable on or after the Closing Date to Sovereign or any
Sovereign Subsidiary; or (vi) any contract (other than this Agreement) limiting
the freedom of any Peoples Subsidiary to engage in any type of banking or bank-
related business permissible under law.

          (b) True and correct copies of agreements, plans, arrangements and
instruments referred to in Section 2.08(a) have been provided to Sovereign on or
before the date hereof, are listed on the Peoples Disclosure Schedule and are in
full force and effect on the date hereof and neither Peoples nor any Peoples

          Section 2.09  Ownership of Property; Insurance Coverage.
                        ----------------------------------------- 

          (a) Peoples and the Peoples 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 Peoples or any Peoples
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 Peoples Regulatory
Reports and in the Peoples 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.  Peoples and the Peoples Subsidiaries, as lessee,
have the right under valid and subsisting leases of real and personal properties
used by Peoples 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.  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 Peoples Financials.

          (b) With respect to all agreements pursuant to which Peoples or any
Peoples Subsidiary has purchased securities subject to an agreement to resell,
if any, Peoples or such Peoples 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.

                                       20

 
          (c) Peoples and the Peoples Subsidiaries currently maintain insurance
considered by Peoples to be reasonable for their respective operations and
similar in scope and coverage to that maintained by other businesses similarly
engaged.  Neither Peoples nor any Peoples 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.  There are presently
no material claims pending under such policies of insurance and no notices have
been given by Peoples or Trenton Savings under such policies.  All such
insurance is valid and enforceable and in full force and effect, and within the
last three years Peoples and Trenton Savings have received each type of
insurance coverage for which they have applied and during such periods have not
been denied indemnification for any material claims submitted under any of their
insurance policies.

          Section 2.10  Legal Proceedings.  Except as set forth in the Peoples
                        -----------------                                     
Disclosure Schedule, neither Peoples nor any Peoples Subsidiary is a party to
any, and there are no pending or, to the best of Peoples' knowledge, threatened
legal, administrative, arbitration or other proceedings, claims (whether
asserted or unasserted), actions or governmental investigations or inquiries of
any nature (i) against Peoples or any Peoples Subsidiary, (ii) to which Peoples
or any Peoples 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 Peoples 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 Peoples.

          Section 2.11  Compliance With Applicable Law.
                        ------------------------------ 

          (a) Peoples and Peoples 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 Peoples.

          (b) Neither Peoples nor any Peoples Subsidiary has received any
notification or communication from any Regulatory Authority (i) asserting that
Peoples or any Peoples 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 Peoples

                                       21

 
or any Peoples Subsidiary; (iii) requiring or threatening to require Peoples or
any Peoples Subsidiary, or indicating that Peoples or any Peoples 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 Peoples or any Peoples
Subsidiary, including without limitation any restriction on the payment of
dividends; or (iv) except for the order issued by the OTS in connection with its
conversion in 1997, directing, restricting or limiting, or purporting to direct,
restrict or limit, in any manner the operations of Peoples or any Peoples
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 Peoples nor any Peoples Subsidiary has consented to or
entered into any Regulatory Agreement except in connection with its conversion.
Peoples has no reason to believe that it will not receive regulatory approval
for the Merger.  Peoples received a rating of "satisfactory" in connection with
its last CRA examination.

          Section 2.12  ERISA.  Peoples has previously delivered to Sovereign
                        -----                                                
true and complete copies of all employee pension benefit plans within the
meaning of ERISA Section 3(2), including profit sharing plans, employee stock
ownership plan, stock purchase plans, deferred compensation and supplemental
income plans, supplemental executive retirement plans, employment agreements,
annual executive and administrative incentive plan 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 Peoples
Disclosure Schedule, sponsored 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 Peoples or any Peoples
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 Peoples, any
Peoples Subsidiary, nor any pension plan maintained by Peoples or any Peoples
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 Peoples, except liabilities to the Pension
Benefit Guaranty Corporation pursuant to ERISA Section 4007, all of which

                                       22

 
have been fully paid, nor has any reportable event under ERISA Section 4043
occurred with respect to any such pension plan which would result in a Material
Adverse Effect.  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 Peoples nor any Peoples Subsidiary has incurred or is subject to any
liability under ERISA Section 4201 for a complete or partial withdrawal from a
multiemployer 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
Peoples or any Peoples 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 Peoples.  Peoples and
the Peoples 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 material
compliance with Section 1862(b)(1) of the Social Security Act.  The forms of the
Peoples' proposed 1999 Stock Option Plan and Peoples' proposed 1999 Management
Recognition Award Plan are set forth in the Peoples Disclosure Schedule.

          Section 2.13  Brokers, Finders and Financial Advisors; Fairness

- -------                                                                         
connection with transactions contemplated by this Agreement, neither Peoples nor
any Peoples 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 Peoples 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 Peoples
Financials.  The Peoples Disclosure Schedule shall contain as an exhibit the
engagement letter between Peoples and Berwind.  Berwind has provided Peoples
with its written opinion to the effect that, as of the date of approval of this
Agreement by the Board of Directors of Peoples,

                                       23

 
the Exchange Ratio is fair to Peoples shareholders from a financial point of
view.

          Section 2.14  Environmental Matters.  To the knowledge of Peoples,
                        ---------------------                               
neither Peoples nor any Peoples Subsidiary, nor any properties operated by
Peoples or any Peoples Subsidiary during Peoples' use or ownership 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 Peoples.  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 Peoples,
threatened, relating to the liability of any property owned or operated by
Peoples or any Peoples Subsidiary under any Environmental Law.

          Section 2.15  Allowance for Losses.  The allowance for loan losses

and to be shown, on the balance sheets contained in the Peoples Financials have
been, and will be, established in accordance with the requirements of GAAP and
all applicable regulatory criteria.

          Section 2.16  Information to be Supplied.  The information to be
                        --------------------------                        
supplied by Peoples and Trenton Savings for inclusion in the Registration
Statement (including the Prospectus/Proxy Statement) and/or any information
Peoples filed with the SEC under the  Exchange Act which is incorporated by
reference into 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 Peoples and up to and including the date
of the meeting of shareholders of Peoples 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 Peoples for
inclusion in the Applications will, at the time such documents are filed with
any Regulatory Authority and up to and including the date of the attainment of
any required regulatory approvals or consents, be accurate in all material
respects.

          Section 2.17  Securities Documents.  Peoples has delivered to
                        --------------------                           
Sovereign copies of its (i) annual report on SEC Form 10-K for the year ended
December 31, 1997, (ii) quarterly reports on SEC Form 10-Q for the quarters
ended March 31, 1998 and June 30, 1998 and (iii) proxy materials used in
connection with its meeting of shareholders held in 1998.  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 in the
                        --------------------------                             
Peoples' Securities Documents, in the footnotes to the Peoples Financials, or in
the Peoples Disclosure Schedule, Peoples 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 Peoples (except a Peoples
Subsidiary).  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 risks or unfavorable features.  No loan
or credit accommodation to any Affiliate of Peoples 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 Peoples nor
Trenton Savings 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
Trenton Savings is inappropriate.

          Section 2.19  Schedule of Termination Benefits.  The Peoples
                        --------------------------------              
Disclosure Schedule includes a schedule of the present value as of December 31,
1998 of termination benefits and related payments which would be payable to the
individuals identified thereon, excluding any options to acquire Peoples Common
Stock granted to such individuals, under any and all employment agreements,
special termination agreements, supplemental executive retirement plans,
deferred bonus plans, deferred compensation plans, salary continuation plans, or
any other pension benefit or welfare benefit plan maintained by Peoples solely
for the benefit of executive officers of Peoples or any Peoples Subsidiary (the
"Benefits Schedule"), assuming their employment is terminated as of April 2,
1999 and the Closing Date occurs on April 1, 1999.  No other individuals are
entitled to benefits under any such plans.  The present value of the termination
benefits and related payments specified, including required gross-up payments
under Section 280G of the IRC, on the Benefit Schedule with respect to each
named individual (based on a 6% per annum discount factor) is true and correct
in all material respects.  Except as set forth in Peoples Disclosure Schedule,
as of the date of this Agreement, no Peoples director had deferred any
compensation accrued by Peoples.

relating to or affecting

                                       25

 
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 Peoples.

                        ------------------------------------                    
Section 203 of the DGCL do not and will not apply to this Agreement or the
transactions contemplated hereby.

          Section 2.22  Labor and Employment Matters.  To the knowledge of
                        ----------------------------                      
Peoples, neither Peoples nor any Peoples Subsidiary, nor any facilities owned or
operated by Peoples or any Peoples Subsidiary has been or is in violation of or
is liable under any Labor and Employment Law, which violation or liability,
individually or in the aggregate, resulted in, or will result in, a Material
Adverse Effect with respect to Peoples.  There are no legal, administrative,
arbitration or other proceedings, demands, claims, notices or investigations
(including without limitation notices, demand letters or requests for
information from any federal, state or local commission, agency or board)

the liability of Peoples or any Peoples Subsidiary under any Labor and
Employment Law.

reasonably expect to receive, a rating level of "Needs Improvement" or
"Unsatisfactory" on its Year 2000 Report of Examination from the OTS, as those
terms are defined in the OTS CEO Memo dated April 30, 1998.  Peoples has made
available to Sovereign a complete and accurate copy of its plan including an
estimate of the anticipated associated costs, for addressing the issues set
forth in the statements of the Federal Financial Institutions Examination
Council, dated May 5, 1997, entitled "Year 2000 Project Management Awareness,"
and December 1997, entitled "Safety and Soundness Guidelines Concerning the Year
2000 Business Risk," as such issues affect Peoples.  Between the date hereof and
the Effective Date, Peoples shall use commercially practicable efforts to
implement its plan.

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

benefit plans, policies, agreements and arrangements, all of which are set forth
on the Sovereign Disclosure Schedule, sponsored 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

plans filed by them,

                                       33

 
respectively, with any government agency, and (iii) all rulings and
determination letters which pertain to any such plans.  Neither Sovereign, any
Sovereign Subsidiary, nor any 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

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

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 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.

     each case as may be required by applicable law;

               (vii)  change any method, practice or principle of accounting,

          Section 4.02  Access; Confidentiality.
                        ----------------------- 

          (a) From the date of this Agreement through the Closing Date, Peoples
or Sovereign, as the case may be, shall afford to, and shall cause each Peoples
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 Peoples 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) Peoples 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, Peoples shall permit
employees of Sovereign reasonable access to and participation in matters
relating to problem loans, loan restructurings and loan work-outs of Peoples and
the Peoples Subsidiaries, provided that nothing contained in this subparagraph
shall be construed to grant Sovereign or any Sovereign employee any final
decision-making authority with respect to such matters.

          (d) If the transactions contemplated by this Agreement shall not be
consummated, Peoples and Sovereign will comply with the terms of the
confidentiality agreement dated August 28, 1998 and each destroy or return all
documents and records obtained from the other party or its representatives,
during the course of its investigation and will cause all information with
respect to the other party obtained pursuant to this Agreement or preliminarily
thereto to be kept confidential, except to the extent such information becomes
public through no fault of the party to whom the information was provided or any
of its representatives or agents and except to the extent disclosure of any such
information is legally required.  Peoples and Sovereign shall each give prompt
notice to the other party of any contemplated disclosure where such disclosure
is so legally required.

          Section 4.03  Regulatory Matters and Consents.
                        ------------------------------- 

          (a) Peoples and Sovereign shall prepare a Prospectus/Proxy Statement
to be mailed to shareholders of Peoples in connection with Peoples' meeting of
shareholders contemplated to be held on or about April 15, 1999 and the
transactions contemplated hereby, and to be filed by Sovereign

                                       40

 
with the SEC in the Registration Statement, which Prospectus/Proxy statement
shall conform to all applicable legal requirements.  Sovereign shall, following
the preparation thereof, file the Registration Statement with the SEC and
Peoples 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 Peoples, 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 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 Peoples with as many
copies of such Registration Statement and all amendments thereto promptly upon
the filing thereof as Peoples may reasonably request.

          (b) Sovereign and Peoples 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 complete the transactions contemplated by this
Agreement.

          (c) Peoples will furnish Sovereign with all information concerning
Peoples and Peoples 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 Peoples 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 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

                                       41

 
relating to completion of the transactions contemplated hereby and thereby.

          (e) Sovereign will promptly furnish Peoples with copies of all written
communications to, or received by Sovereign or any Sovereign Subsidiary from,
any Regulatory Authority in respect of the transactions contemplated hereby.

          Section 4.04  Taking of Necessary Action.
                        -------------------------- 

          (a) Sovereign and Peoples shall each use its 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 using its best efforts 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 Peoples nor any
Peoples 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 Peoples or from exercising
its rights under this Agreement or the Stock Option Agreement.

          (b) Sovereign shall not take any action which would result in any of
the representations and warranties of Sovereign 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 law.

          Section 4.05  Certain Agreements.
                        ------------------ 

          (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 Peoples 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 fact that he is or
was a director, officer or employee of Peoples, any of the Peoples' Subsidiaries

                                       42

 
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 or
required by the DGCL and the Certificate of Incorporation and Bylaws of Peoples.
On or after the Effective Date, Sovereign shall indemnify, defend and hold
harmless all prior and then-existing directors and officers of Peoples and any
Peoples Subsidiary, against (i) all losses, claims, damages, costs, expenses,
liabilities or judgments or amounts that are paid in settlement (with the
approval of Sovereign which approval shall not be unreasonably withheld) 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 Peoples or any Peoples
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 Peoples
or any Peoples Subsidiary as of the date hereof including the right to
advancement of expenses, provided, however, that any such officer, director or
employee of Peoples or any Peoples Subsidiary may not be indemnified by
Sovereign and/or Sovereign Bank if such indemnification is prohibited by
applicable law.

          (b) Sovereign shall maintain Peoples' 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 Peoples 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.

                                       43

 
          (c) Sovereign agrees to honor and Sovereign agrees to cause Sovereign
Bank to honor all terms and conditions of all existing employment contracts and
special termination agreements disclosed in the Peoples Disclosure Schedule.  To
the extent that the employment of any of the employees listed on the Peoples
Disclosure Schedule is terminated after the Effective Date, Sovereign agrees to
enter into consulting arrangements with such individuals for the amounts and for
the time periods set forth on the Peoples Disclosure Schedule.

          (d)  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, Peoples shall not and Peoples 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 (unless
such person's fiduciary duty as a director of Peoples legally requires such
person to do so and such person is so advised in a written opinion of counsel to
Peoples), (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.
Peoples 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.  Peoples 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, Peoples.  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 Peoples or a Peoples Subsidiary, (ii) a purchase, lease
or other acquisition of all or a substantial portion of the assets or
liabilities of Peoples or a Peoples Subsidiary or (iii) a

                                       44

 
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 Peoples (other than as permitted by Section 4.01(a)(ii)
hereof) or a Peoples 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 Sections 5.01(c) and
5.02(c) hereof, as applicable.

          Section 4.08  Conduct of Sovereign's Business.  From the date of this
                        -------------------------------                        
Agreement to the Closing Date, Sovereign will 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 goodwill of
customers of Sovereign and Sovereign Subsidiaries and others with whom business
relationships exist.

          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), Peoples 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, Peoples and Sovereign will deliver to the other party its
Annual Report on Form 10-K.  Within 25 days after the end of each month, Peoples
will deliver to Sovereign a consolidated balance sheet and a consolidated
statement of operations, without related notes, for such month.

          (b)  Peoples shall provide to Sovereign a copy of the minutes of any
meeting of the Board of Directors of

                                       45

 
Peoples or any Peoples Subsidiary, 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 Peoples.
                        -------------------------------------

     Section 6.01(d) hereof;

               (x)  Shareholders' Meeting.  Peoples shall take all action

          Section 4.11  Employee Benefits and Termination Benefits.
                        ------------------------------------------ 

          (a) Employee Benefits.  On and after the Effective Date, the employee
              -----------------                                                
pension (including employee stock ownership plans) and welfare benefit plans of
Sovereign and Peoples (as well as any other plan of Peoples 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 or
terminated, 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 Peoples and Peoples 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.

                                       49

 
               (ii)  Trenton Savings Bank FSB Employee Stock Ownership Plan
                     ------------------------------------------------------
     ("Peoples ESOP").  After the Effective Date, Sovereign will not merge the
     ----------------                                                         
     Peoples ESOP until and unless required by applicable law, and in no event
     prior to December 31, 2000.

               (iii)  Sovereign Defined Benefit Pension Plan ("DB Plan").
                      --------------------------------------------------  
     Employees of Peoples and Peoples 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 Peoples or a Peoples Subsidiary credited
     to each such employee under Peoples' applicable qualified plan, 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)  Sovereign 401(k) Retirement Savings Plan ("401(k) Plan").
                     --------------------------------------------------------  
     Employees of Peoples and Peoples 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 Peoples or a Peoples Subsidiary
     credited to each such employee under Peoples' 401(k) Plan as of the
     Effective Date, 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.

               (v)  Peoples Savings Plan ("401(k) Plan").  After the Effective
                    ------------------------------------                      
     Date, Sovereign will initially continue to maintain Peoples' 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.

               (vi)  Sovereign and Peoples 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 Peoples 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 Peoples and Peoples Subsidiaries
     generally shall be entitled only to the sum of (A) the benefits accrued
     under the Peoples Excess

                                       50

 
     Benefit Plan(s) as of the plan consolidation, and (B) the benefits accrued
     thereafter under the combined Excess Benefit Plan.

               (vii)  Peoples 1996 and 1999 Recognition and Retention Plan
                      ----------------------------------------------------
     ("1996 RRP" and "1999 RRP").  The 1996 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 Peoples Common Stock, whether
     before or after the Effective Date.  No further grants or awards shall be
     made under the 1996 RRP following the date of this Agreement.  Peoples may
     adopt the 1999 RRP in the form set forth in the Peoples Disclosure
     Schedule.  The 1999 RRP will permit the grant or award of a maximum of
     578,000 shares of Peoples Common Stock to the individuals and in the
     amounts set forth on the Peoples Disclosure Schedule; provided, however,
     that the 1999 RRP shall provide that grants or awards under the 1999 RRP
     shall provide for three-year vesting and shall not automatically vest upon
     the "change in control" which would occur on the Effective Date as a result
     of the Merger.

               (viii)  Peoples 1996 and 1999 Stock Option Plans ("1996 Option
                       ------------------------------------------------------
     Plan") and ("1999 Option Plan").  The 1996 Option Plan 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 of options to purchase Peoples Common Stock,
     whether before or after the Effective Date.  No further grants of stock
     options will be made under the 1996 Option Plan following the date of this
     Agreement.  Peoples may adopt the 1999 Option Plan in the form set forth in
     the Peoples Disclosure Schedule.  The 1999 Option Plan will permit the
     grant of stock options to purchase a maximum of 1,428,000 shares of Peoples
     Common Stock to the individuals and in the amounts set forth on the Peoples
     Disclosure Schedule; provided, however, that options granted under the 1999
     Option Plan shall provide for three-year vesting and shall not
     automatically vest upon the "change in control" which would occur on the
     Effective Date as a result of the Merger.

               (ix)  Welfare Benefit Plans.  After the Effective Date, the
                     ---------------------                                
     welfare benefit plans of Sovereign and Peoples (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

                                       51

 
     employer and employee) as it deems appropriate under the circumstances.  In
     the event of any termination of or consolidation of a Peoples welfare plan
     with any Sovereign welfare plan, all employees of Peoples and Peoples
     Subsidiaries who are eligible for continued coverage under the Peoples
     welfare plan shall have immediate coverage under any successor welfare plan
     without the necessity of satisfying a waiting period for coverage of any
     pre-existing condition.  Except for the individuals set forth in the
     Peoples Disclosure Schedule, Sovereign does not provide welfare benefits to
     part-time employees or retired employees.

               (x)  Peoples Bonus Plans and Arrangements.  Peoples 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 the 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 twenty-five
     percent (25%) of the aggregate amount of bonuses payable for the calendar
     year ending December 31, 1998.

               (xi)  Other Peoples 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 Peoples plans to employees or directors, including, without
     limitation, the granting of stock options, stock appreciation rights,
     restricted stock, and performance shares.

          (b) Termination Benefits.  Peoples shall use its best efforts to cause
              --------------------                                              
to be delivered to Sovereign within five (5) business days following execution
of this Agreement with respect to each executive officer named on the Benefits
Schedule included in the Peoples Disclosure Schedule, the written acknowledgment
of each such individual in the form attached hereto as Exhibit 4 pursuant to
which each such individual agrees and acknowledges that the dollar amount set
forth opposite such individual's name on such Benefits Schedule is the entire
amount that would be due to such individual under any employment agreement,
special termination agreement, supplemental executive retirement plan, deferred
bonus plan, deferred compensation plan, salary continuation plan, or any other
pension benefit or welfare benefit plan maintained by Peoples solely for the
benefit of officers of Peoples or Peoples Subsidiaries assuming a termination of
such individual's employment on April 2, 1999, and April 1, 1999 as the Closing
Date.  Peoples and Sovereign acknowledge and agree that the amounts shown on the

                                       52

 
Benefits Schedule and the letter of acknowledgement for each officer named 
herein reflect a good faith estimate of the amounts that will be payable to such
individuals under the circumstances described and may be subject to adjustment
upon an actual termination of employment in order to reflect increases in such
individuals' compensation and benefit plans consistent with past practices for
routine periodic increases.

          (c) Severance Policy.  Sovereign agrees to cause Sovereign Bank to
              ----------------                                              
provide severance pay, as set forth below, to any employee of Peoples whose
employment is terminated hereafter in connection with the Merger up to three (3)
months beyond the Effective Date, because (i) such employee's position is
eliminated, or (ii) such employee is not offered or retained in comparable
employment (i.e., a position of generally similar job description or
responsibilities in a location within a thirty (30)-mile radius from either such
employee's work location with Peoples or residence), excluding any employee who
has an existing employment or consulting agreement with Peoples or any Peoples
Subsidiary, who has accepted an offer from Sovereign of noncomparable employment
or whose employment is terminated for Cause (as defined below), provided such
                                                                --------     
employee executes such documentation as Sovereign may reasonably require,
including Sovereign's customary form of release provided to Peoples prior to the
execution of this Agreement and provided such employee does not leave employment
with Peoples or Sovereign prior to the employment termination date or any
extension thereof established or adjusted by Sovereign:  (i) senior officers
(within the meaning of Peoples' Severance Pay Policy) shall be entitled to two
and one-half (2-1/2) weeks' pay for each full year of continuous service with a
minimum severance benefit of thirty (30) weeks' pay; (ii) junior officers
(within the meaning of Peoples' Severance Pay Plan) shall be entitled to two and
one-half (2-1/2) weeks pay for each full year of continuous service with a
minimum severance benefit of sixteen (16) weeks' pay and a maximum severance
benefit of thirty (30) weeks' pay; (iii) regular full-time employees who are
exempt employees under FLSA shall be entitled to two and one-half (2-1/2) weeks'
pay for each full year of continuous service with a minimum severance benefit of
eight (8) weeks' pay and a maximum severance benefit of thirty (30) weeks' pay;
(iv) regular full-time employees who are nonexempt employees under FLSA shall be
entitled to two and one-half (2-1/2) weeks' pay for each full year of continuous
service with a minimum severance benefit of four (4) weeks' pay and a maximum
severance benefit of thirty (30) weeks' pay; and (v) part-time, peak-time and
temporary employees shall not be entitled to any severance benefits.  For
purposes of this Section 4.11(c), "Cause" shall mean termination because of the
employee's personal dishonesty, failure to meet established performance goals
and standards, 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 Peoples employees under this

                                       53

 
subsection are the only severance benefits payable by Peoples to such employees
(excluding severance benefits provided under existing employment or consulting
agreements or as otherwise required by law), except for employees who do not
execute the documentation required by Sovereign, which employees shall be
entitled to the termination benefits provided under Peoples' normal severance
policies.  The benefits payable to Peoples' employees under this subsection or
otherwise shall in any event 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.

          (d) Intention Regarding Future Employment.  Sovereign and Sovereign
              -------------------------------------                          
Bank shall use their reasonable best efforts to inform the employees of Peoples
at least sixty (60) days prior to the Effective Date of the likelihood of such
employees having continued employment with Sovereign Bank following the
Effective Date and, where appropriate in Sovereign Bank's judgment, it will
consider for employment opportunities at Sovereign Bank such employees who would
otherwise be terminated.

          (e) Retention Bonuses.  Notwithstanding subparagraph (c) above, each
              -----------------                                               
employee of Peoples or of Trenton Savings identified in the Peoples Disclosure
Schedule shall be entitled to receive a "retention" bonus from Peoples (or the
applicable Peoples Subsidiary) as determined by the executive officers of
Peoples (after consultation with Sovereign) and as set forth on the Peoples
Disclosure Schedule in the event that such employee remains an employee of
Peoples (or the applicable Peoples Subsidiary), until the date the systems
conversion occurs (or such other date established or adjusted by Sovereign not
to exceed 90 days following the date the system conversion occurs) or is
terminated prior to the date of the systems conversion, but after the Effective
Date, and satisfactorily fulfills the duties and responsibilities of the
position of such employee of Peoples (or the applicable Peoples Subsidiary)
through the employee's termination date; provided that retention bonuses, in the
aggregate, shall not exceed $2,400,000.

          Section 4.12  NASDAQ Listing.  Sovereign shall use all reasonable best
                        --------------                                          
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 System, subject to official notice of issuance, as of or prior
to the Effective Date.

          Section 4.13  Affiliate Letter.  Concurrently with, or within five (5)
                        ----------------                                        
business days after, the execution and delivery of this Agreement, Peoples shall
cause to be delivered to Sovereign the Letter Agreement attached hereto as
Exhibit 1, executed by each director, officer and any Affiliate of Peoples.

          Section 4.14  Publication of Combined Financial Results.  Sovereign
                        -----------------------------------------            
shall use its reasonable best efforts to

                                       54

 
publish as soon as possible, but no later than thirty (30) days after the end of
the first  month after the Effective Date in which there are at least 30 days of
post-Merger combined operations, combined revenues and net income figures as
contemplated by and in accordance with the terms of SEC Accounting Series
Release No. 135, provided, however, that Sovereign may delay publishing such
information for such period of times as it, in its good faith reasonable
judgment, deems necessary or desirable to achieve a bona fide corporate purpose.

          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  Advisory Board.  On the Effective Date, Sovereign Bank
                        --------------                                        
shall establish the Peoples Advisory Board (the "Peoples Advisory Board"), which
shall consist of all members of the Peoples Advisory Board immediately prior to
the Effective Date.  Each member of the Peoples Advisory Board shall be paid an
annual retainer of $1,000.  The Peoples Advisory Board shall be initially
established for a term of one year from the Effective Date.  Thereafter, for a
period of two additional years, Sovereign shall either continue the Peoples
