                           "Year 2000 Compliant"  means  information  technology
         that accurately  processes  date/time data (including,  but not limited
         to, calculating, comparing, and sequencing) from, into, and between the
         years  1999 and 2000 and leap year  calculations  (Year  2000 is a leap

         date/time data with it.


                                   ARTICLE II

                                THE TRANSACTIONS

                  2.1      The Share Exchange.

                         (A) The Share Exchange.  At the Effective Time, each of
the  outstanding  shares of Sterling  Common Stock shall be exchanged for $21.54
(as it may be  adjusted  pursuant to Section  3.4) in cash (the "Share  Exchange
Consideration")  to be paid by  Mason-Dixon  in  accordance  with  the  MGCL and
Mason-Dixon   shall  become  the  sole   stockholder  of  Sterling  (the  "Share
Exchange").  At any time prior to the Effective Time, Mason-Dixon may change the
method  of  effecting  the  combination   with  Sterling   (including,   without
limitation,  the  provisions  of this  Article II) if and to the extent it deems
such change to be necessary,  appropriate or desirable;  provided, however, that
no such change shall (i) alter or change the amount or kind of  consideration to
be issued to holders of Sterling  Common Stock as provided for in this Plan,  or
(ii) materially impede or delay consummation of the Transactions.

                         (B) Effectiveness of the Share Exchange. Subject to the
satisfaction  or waiver of the  conditions  set forth in Article  VII, the Share
Exchange  shall become  effective  upon the filing in the office of the Maryland
State  Department of Assessments  and Taxation (the "SDAT") of articles of share
exchange or such later date and time as may be set forth in such  articles.  The
Share Exchange shall have the effects prescribed in the MGCL.

                  2.2      Cancellation of Sterling Stock Options.

                         (A) After the  Effective  Time and before the Corporate
Merger and the Bank  Merger,  Mason-Dixon  shall  cause  Sterling  to cancel all
outstanding Sterling Stock Options (the "Option  Cancellation") in consideration
of  payment  to  the  holders  thereof  of  the  Aggregate  Option  Cancellation
Consideration.  For each share of Sterling Common Stock the holder of a Sterling
Stock Option is eligible to purchase, the holder shall receive $21.54 (as it may
be adjusted pursuant to Section 3.4) minus the price which, under the applicable
Sterling  Stock Option  agreement,  the holder must pay to exercise the Sterling
Stock Option (the "Option

Cancellation  Consideration").  The Option  Cancellation  Consideration shall be
paid in accordance with the terms of the written agreements between Sterling and
the  holders  of  the  Sterling   Stock   Options   (the  "Option   Cancellation
Agreements.")

                         (B) On the Effective Date, after the Effective Time and
before  the  Corporate  Merger  and the Bank  Merger,  Mason-Dixon  shall  cause
Sterling  to cause the Bank to declare  and pay a cash  dividend  to Sterling of
such amount of cash as Mason-Dixon deems appropriate or such lesser amount as is
approved  by the  appropriate  federal  banking  authorities  and  the  Maryland
Commissioner of Financial Regulation (the "Dividend").

                         (C)  No  later  than  the  Effective  Date,  after  the
Effective Time and before the Corporate Merger and the Bank Merger,  Mason-Dixon
shall  make a  contribution  of capital to  Sterling  in an amount  equal to the
difference  between the amount of cash required for the Option  Cancellation and
the Dividend.

                  2.3 MDMS and Sterling Merger. As soon after the Effective Time
as Mason- Dixon may deem appropriate, but prior to the Bank Merger and not prior

Merger shall have the effects  prescribed in the MGCL and the Maryland Financial
Institutions Article ("MFA").

                         (B) Charter; Bylaws;  Directors;  Officers. The charter

immediately  prior to the Bank Merger  becoming  effective.  The  directors  and

                  2.5 Effective Date, Effective Time and Closing. Subject to the
satisfaction  or waiver of the  conditions  set forth in  Article  VII which are
capable  of being  satisfied  prior to  Closing,  the  parties  shall  cause the

Date at the offices of Gordon,  Feinblatt,  Rothman,  Hoffberger  and Hollander,
LLC, 233 East Redwood Street, Baltimore, Maryland, 21202.

                                   ARTICLE III

                       CONSIDERATION; EXCHANGE PROCEDURES

                  3.1  Share  Exchange  Consideration.  At the  Effective  Time,
automatically by virtue of the Share Exchange and without any action on the part
of any  Person,  each share of  Sterling  Common  Stock  issued and  outstanding
immediately  prior to the Effective  Time shall become and be converted into the
right to receive $21.54 (as it may be adjusted  pursuant to Section 3.4) in cash
from Mason-Dixon.

                  3.2 Rights as Stockholders;  Stock Transfers. At the Effective
Time,  holders of  Sterling  Common  Stock  shall cease to be, and shall have no
rights as, stockholders of Sterling, other than to receive any dividend or other
distribution  with  respect to such  Sterling  Common  Stock with a record  date
occurring prior to the Effective Time and the consideration  provided under this
Article III or with respect to  dissenting  shares,  such rights as are provided
under the MGCL.  After the  Effective  Time,  there shall be no transfers on the
stock transfer  books of Sterling of shares of Sterling  Common Stock except for
transfers to Mason-Dixon.

                  3.3      Payment Procedures.

                         (A)  Deposit  of  Cash.  No  later  than  the  Closing,
Mason-Dixon  shall  cause cash to be  deposited  in escrow  with an  institution
mutually  satisfactory to Sterling and Mason-Dixon ("Escrow Agent") in an amount
equal to $8,616,043.08  (as it may be adjusted pursuant to Section 3.4) which is
the total Share Exchange Consideration for all of Sterling Common Stock.

                         (B)  Exchange  of Shares for Cash.  Within 5 days after
the Effective Date, the Escrow Agent will send a notice and transmittal  form to
each holder of a certificate  evidencing  Sterling  Common Stock,  advising such
holder of the procedure for surrendering to the Escrow Agent such certificate or
certificates  in exchange  for payment.  Except with  respect to any  Dissenting
Shares,  each holder of a certificate  evidencing  Sterling  Common Stock,  upon
surrender of such certificate to the Escrow Agent,  together with such letter of
transmittal,  shall  be  entitled  to  receive  promptly  in  exchange  for such
certificate $21.54 (as it may be adjusted



                                     - 13 -

pursuant to Section 3.4) per share of Sterling Common Stock  represented by such
certificate. As promptly as practicable after each such holder's certificate has
been  surrendered  (but not more than 3 business  days  thereafter),  the Escrow
Agent will mail to each holder of Sterling Common Stock whose  certificates  for
shares,  which are not Dissenting  Shares,  have been  surrendered to the Escrow
Agent, a check in the appropriate amount. No interest will be paid or accrued on
the cash payable upon  surrender of such  certificates.  If payment for Sterling
Common Stock is to be made to any person other than the registered holder of the
Sterling Common Stock  surrendered,  the amount of any stock transfer or similar
taxes  (whether  imposed on the  registered  holder or such  person)  payable on
account of the transfer of the Sterling  Common Stock will be deducted  from the
amount to be paid by the Escrow  Agent,  or the Escrow  Agent may refuse to make
such  payment,  unless  satisfactory  evidence of the payment of such taxes,  or
exemption  therefrom,  is  submitted  to  the  Escrow  Agent.  Shares  to  which
dissenters  rights have been properly  perfected shall be treated by Mason-Dixon
in the manner provided by Section 3.3(D).

                         (C) Status of Certificates.  At and after the Effective
Time,  each  outstanding  certificate  which  previously  represented  shares of
Sterling Common Stock (except any Dissenting  Shares,  which  Dissenting  Shares
shall evidence only the rights  specified in Section  3.3(D)) shall be deemed to
evidence  only the right to receive cash in  accordance  with the  provisions of
this  Section 3.3 and shall not be deemed to confer upon the holder  thereof any
voting, dividend or other rights of a stockholder of Mason-Dixon,  Sterling, the
Continuing  Corporation,  or the  Continuing  Bank.  No  interest  on any amount
payable to any former holder of Sterling Common Stock shall accrue or be paid to
such holder for the period following the Effective Time.

                         (D)   Dissenting   Shares.   Except  for   purposes  of
determining  the total  number of shares of  Sterling  Common  Stock  issued and
outstanding  immediately prior to the Effective Time, the provisions of Sections
3.1, 3.3(A), 3.3(B), 3.3(C) and 3.3(E) shall not apply to any shares of Sterling
Common Stock held by holders who elect dissenter and appraisal  rights under the
MGCL  ("Dissenting  Shares").  Any  holder of  Dissenting  Shares  shall have in
consideration for the cancellation of such Dissenting Shares only such rights as
may be given to such  holder  under the MGCL,  in the manner and  subject to the
procedures and conditions  therein provided,  unless and until such holder shall
have  failed to  perfect,  or shall have  effectively  withdrawn  or lost,  such
holder's right to appraisal of any payment for such holder's  shares of Sterling
Common  Stock under the MGCL,  at which time such shares  shall be canceled  and
converted  into the right to  receive  cash in the  amount  provided  in Section
3.3(B) only, and no other consideration shall be paid.

                         (E) Abandoned Property.  Notwithstanding the foregoing,
no party  hereto shall be liable to any former  holder of Sterling  Common Stock
for any amount properly  delivered to a public  official  pursuant to applicable
abandoned property, escheat or similar laws.

                  3.4      Adjustment Amount.

                         (A)  The  total  of  the   Aggregate   Share   Exchange
Consideration  and the  Aggregate  Option  Cancellation  Consideration  shall be
reduced by the "Adjustment  Amount" if a duly executed written  agreement by the
landlord  of the Bank's  Parole  Shopping  Center  branch in form and  substance
reasonably  satisfactory  to  Mason-Dixon  consenting  to the  assignment of the
Parole  Shopping  Center  branch lease to and  occupancy of the Parole  Shopping
Center branch location by BoM has not been delivered to Mason-Dixon prior to the
Effective Date or if it has been so delivered, Sterling or its Subsidiaries have
paid  consideration  to the landlord in return for such consent.  The Adjustment
Amount shall be either (as may be applicable) (i) the dollar value of the Bank's
Parole branch leasehold rights as set forth below as of the Effective Date (if a
month end) or as of the most recent month end preceding  the  Effective  Date if
the Effective Date is not a month end:

================================================================================

January 31, 1999                                             263,150

or (ii) the  value of the  consideration  paid to the  landlord  to  secure  the
consent to assignment.

                         (B) The Adjustment  Amount shall be divided by 607,050,
the total number of outstanding  shares of Sterling  Common Stock plus the total
number of shares of Sterling  Common Stock holders of Sterling Stock Options are
eligible to  purchase,  to derive the Share  Exchange  Consideration  and Option
Cancellation  Consideration reduction amount. For example, if the Effective Date
is October 30, 1998, the Adjustment Amount (assuming no payment has been made to
and no consent to assignment received from the landlord) is $270,750,  the Share
Exchange Consideration and Option Cancellation Consideration reduction amount is
$.446,  the Option  Cancellation  Consideration  is $21.094  minus the price per
share of Sterling Common Stock which, under the applicable Sterling Stock Option
agreement,  the holder must pay to exercise the Sterling  Stock Option,  and the
Share  Exchange  Consideration  is  $21.094.  The amount  paid to each holder of
Sterling  Common Stock and Sterling  Stock Option shall be rounded up or down to
the nearest whole cent.

                         REPRESENTATIONS AND WARRANTIES

                  5.1      Disclosure Schedules.

                         (A) On or  prior to the date  hereof,  Mason-Dixon  has
delivered to Sterling a schedule and Sterling  has  delivered to  Mason-Dixon  a
schedule  (respectively,  its "Disclosure  Schedule") setting forth, among other
things,  items the disclosure of which is necessary or appropriate either (i) in
response to an express disclosure  requirement hereof or (ii) as an exception to
one or more  representations or warranties contained in Section 5.3 or 5.4 or to
one or more of its covenants  contained in Article IV or VI; provided,  that (a)
no such  item  is  required  to be set  forth  in a  Disclosure  Schedule  as an
exception to a representation or warranty if its absence would not be reasonably
likely to result in the related  representation  or warranty being deemed untrue
or incorrect,  and (b) the mere inclusion of an item in a Disclosure Schedule as
an exception to a representation or warranty shall not be deemed an admission by
a party  that  such item  represents  a  material  exception  or fact,  event or
circumstance.

                         (B) The  disclosures  in the Disclosure  Schedule,  and
those in any supplement  thereto,  must relate only to the  representations  and
warranties in the Section of the Plan to which they expressly  relate and not to
any other representation or warranty in this Plan.

                         (C)  In the  event  of any  inconsistency  between  the
statements in the body of this Plan and those in the Disclosure  Schedule (other
than an exception  expressly set forth as such in the  Disclosure  Schedule with
respect to a specifically identified representation or warranty), the statements
in the body of this Plan will control.

                  5.2  Updating of  Disclosure  Schedule.  From the date of this
Plan to the Effective Date, each of Mason-Dixon and Sterling agrees that it will
promptly  inform  the  other in  writing  if any  information  set  forth in its
Disclosure  Schedule is not accurate and complete in all material respects as of
such  later  date  and will  promptly  disclose  to the  other  in  writing  any
information  which  arises  after  the date  hereof  and which  would  have been
required  to be  included in its  Disclosure  Schedule  to make such  Disclosure
Schedule  accurate and complete in all material  respects as of such later date;
provided,  however,  that none of such  disclosures  shall be deemed to  modify,
amend  or  supplement  its  representations  and  warranties  or its  Disclosure
Schedule  for  purposes  of any  provision  hereof  unless the other  shall have
consented  thereto in writing.  Material  information and material  inaccuracies
shall be reported and disclosed to the other  promptly.  Immaterial  information
and immaterial  inaccuracies shall be reported and disclosed on the tenth day of
each month after the date hereof.

material misstatement or omission or is otherwise in material noncompliance with
any law, regulation or requirement.

                              (iii)  Sterling  and  its  Subsidiaries   have  no

absolute,   accrued,   contingent,  or  otherwise)  except  for  liabilities  or
obligations  reflected or reserved  against in the Balance  Sheet or the Interim
Balance  Sheet  and  current  liabilities  incurred  in the  Ordinary  Course of
Business since the respective dates thereof.

                              (iv) Since December 31, 1997, (a) Sterling and its
Subsidiaries  have  conducted  their  respective  businesses in the ordinary and

have they ever  been,  a party to, a  sponsor  of, or a  contributor  to (a) any
employee pension benefit plan (as



- - 25 -

defined  in  Section  3(2) of ERISA) (a  "Retirement  Plan"),  (b) any  employee
welfare  benefit plan (as defined in Section 3(1) of ERISA) (a "Welfare  Plan"),
or (c) any employment  contract,  written or unwritten,  or any other  contract,
policy or practice providing compensation or benefits not included in (a) or (b)
(an "Other  Plan").  All Retirement  Plans,  Welfare Plans and Other Plans which
Sterling and its  Subsidiaries  are now or have ever been, a party to, a sponsor
of, or a contributor to are  hereinafter  collectively  referred to as "Employee
Benefit Plans."  Sterling and its  Subsidiaries  have not scheduled or agreed to
future  increases of benefit levels or the creation of new benefits with respect
to any Employee  Benefit  Plan,  nor have such  increases  or new benefits  been
proposed to the Employees.

                              (ii) With respect to each  Employee  Benefit Plan,
Sterling  has  delivered  or made  available to  Mason-Dixon  true,  correct and
complete  copies,  including  amendments,   of  the  following  (to  the  extent
applicable):  (a) the  current  and most  recent  prior  Employee  Benefit  Plan
document  or  other  writing  (including  trust  agreements,   service  provider
agreements,  investment  manager  agreements and insurance  contracts),  (b) the
current and all prior Summary Plan Descriptions (including summaries of material
modifications  thereto) or similar descriptions of Other Plans, (c) the two most
recently filed Form 5500s including all schedules and  attachments,  (d) the two
most recent  determination  letters  issued by the IRS,  (e) the two most recent
actuarial  valuations  and/or allocation  reports,  and (f) any current or prior
employee handbooks or policy manuals which refer to such Employee Benefit Plan.

                              (iii) The assets of Sterling and its  Subsidiaries
are not subject to any liens under ERISA or the Code, and no event has occurred,
and no condition  exists,  which could subject  Sterling and its Subsidiaries or
their  assets  to a  future  liability,  obligation  or lien on  account  of any
Controlled  Group  Benefit  Plan. A  "Controlled  Group  Benefit Plan" means any
Employee  Benefit Plan which  Sterling,  or any entity which must be  considered
together with  Sterling  under  Section  414(b),  (c), (m) or (o) of the Code (a
"Benefit  Plan  Affiliate"),  maintains or at any time  maintained,  or to which
Sterling or any  Benefit  Plan  Affiliate  has at any time  contributed  or been
obligated to contribute.

                              (iv) No Controlled Group Benefit Plan is or at any
time was a "defined  benefit plan" (within the meaning of ERISA Section  3(35)),
nor has Sterling or any Benefit Plan  Affiliate  ever  maintained,  sponsored or
been required to make  contributions  to any defined benefit plan. No Controlled
Group  Benefit  Plan is or at any time was a  "multiemployer  plan"  (within the
meaning of ERISA Section 3(37)),  nor has Sterling or any Benefit Plan Affiliate
ever  maintained,  sponsored  or  been  required  to make  contributions  to any
multiemployer  plan.  No  Controlled  Group Benefit Plan is or at any time was a
"multiple  employer  welfare  arrangement"  (within the meaning of ERISA Section
3(40)),  nor  has  Sterling  or any  Benefit  Plan  Affiliate  ever  maintained,
sponsored or been required to make contributions to any such arrangement.

                              (v) Each Employee  Benefit Plan is, and has at all
times been,  administered,  maintained and operated in compliance with its terms
and in compliance  with all  applicable  provisions  of the Code,  ERISA and all
other federal,  state and local laws (and all rules and regulations  promulgated
or proposed  thereunder).  Each  Employee  Benefit  Plan which  Sterling and its
Subsidiaries  currently  sponsors or contributes to can be amended or terminated
at any time  without  liability  to  Sterling  or its  Subsidiaries  other  than
honoring the Sterling  Stock Options and with respect to accrued  benefits under
any Employee Benefit Plan.

                              (vi) Sterling and its Subsidiaries  have performed
all  obligations  required to be performed by them under any law or by the terms
of each Employee  Benefit Plan, and all  contributions  or payments  deducted by
Sterling and its Subsidiaries  for tax purposes were properly  deductible in the
year for which such deductions were claimed.

                              (vii)  There  are no  actions,  investigations  or
claims of any kind  (other than  routine  benefit  claims  made in the  ordinary
course),  pending or threatened,  with respect to any Employee Benefit Plan, and
no events or omissions  have occurred which could give rise to any such actions,
investigations  or claims.  There have been no audits or  investigations  of any
Employee Benefit Plan by any governmental agency.

                              (viii)  Each   Retirement  Plan  that  is  or  was
intended to constitute a qualified plan under Code Section 401(a) is, and has at
all times been, qualified, in form and operation,  under Code Section 401(a) and
is the subject of a favorable determination letter from the IRS.

                              (ix) With respect to any Retirement  Plan which is
unfunded,  Sterling and its Subsidiaries have adequately provided for, and their
financial  statements  accurately  reflect (in accordance with GAAP consistently
applied),  the amount of all accrued  benefits under such  Retirement  Plan, and
such accrued  benefits  were  computed  based on actuarial  methods,  tables and
assumptions, each of which is itself reasonable.

                              (x) No  Controlled  Group  Benefit  Plan  provides
health,  medical, life insurance or similar benefits to retirees or other former
employees  or their  beneficiaries  (except to the extent  required  under ERISA
Sections  601-608).  Each Employee Benefit Plan covers only employees (or former
employees) of Sterling and its Subsidiaries.

                              (xi) The consummation of the Transactions will not
(a)  entitle  any  current or former  employee  or officer of  Sterling  and its
Subsidiaries to severance pay, parachute payments,  unemployment compensation or
any other payment,  except as expressly provided in this Plan, or (b) accelerate
the time of payment or vesting or increase  the amount of  compensation  due any
such employee or officer except as expressly provided in this Plan.

                              (xii) With  respect to any  Employee  Benefit Plan
that is funded wholly or partially  through an insurance  policy  (including any
"stop loss" policy that applies to such Employee Benefit Plan), there will be no
liability of Sterling and its  Subsidiaries  as of the Effective Time under such
policy  (or  any  ancillary  agreement  to  such  policy)  in  the  nature  of a
retroactive  rate  adjustment,  loss  sharing  arrangement  or other  contingent
liability.  The consummation of the transactions  contemplated by this Plan will
not cause a revocation or material  modification  of any such insurance  policy,
and all such  policies  can be assumed by  Mason-Dixon  at its  option.  Section
5.3(M)(xii) of Sterling's  Disclosure  Schedule includes all insurance  policies
described in this paragraph.

                              (xiii)  Sterling and all Benefit  Plan  Affiliates
have at all times  complied  with the COBRA group  health plan  continuation  of
coverage   requirements   under  ERISA  Sections  601-608  and  the  regulations
promulgated  or  proposed   thereunder.   Section   5.3(M)(xiii)  of  Sterling's
Disclosure  Schedule lists all persons who (a) currently have or are entitled to
COBRA  continuation  coverage  under any  Employee  Benefit  Plan  currently  or
previously  maintained by Sterling and all Benefit Plan  Affiliates,  specifying
the date such coverage or entitlement thereto began for each person and the date
the maximum  required  period of coverage  for such person will end, and (b) are
eligible  to elect such  COBRA  continuation  coverage  or to have it elected on
their  behalf on account of a  qualifying  event which has  already  occurred or
which will occur prior to Closing.

                              (xiv) No loan is outstanding  between Sterling and
its  Subsidiaries  and any  Employees.  No employer  securities,  employer  real
property or other employer  property is held as an asset of any Employee Benefit
Plan.

                         (N)  Labor  Matters.  Neither  Sterling  nor any of its
Subsidiaries is a party to or is bound by any collective  bargaining  agreement,
contract  or  other  agreement  or  understanding  with a labor  union  or labor
organization,  nor is  Sterling  or any of its  Subsidiaries  the  subject  of a
proceeding  asserting  that it or any such  Subsidiary  has  committed an unfair
labor  practice  (within the meaning of the  National  Labor  Relations  Act) or
seeking to compel  Sterling  or any such  Subsidiary  to bargain  with any labor
organization as to wages or conditions of employment, nor is there any strike or
other  labor  dispute  involving  it or any of its  Subsidiaries  pending or, to
Sterling's  knowledge,  threatened,  nor  is  Sterling  aware  of  any  activity
involving  its or any  of its  Subsidiaries'  employees  seeking  to  certify  a
collective bargaining unit or engaging in other organizational activity.

                         (O)  Environmental  Matters.  Neither  the  conduct nor
operation  of Sterling or its  Subsidiaries  nor any  condition  of any property
presently or  previously  owned,  leased or operated by any of them  (including,
without limitation,  in a fiduciary or agency capacity), or on which any of them
holds a Lien, violates or violated during the period of such ownership, lease or
operation Environmental Laws and no condition has existed or event has



                                     - 28 -

2:10/16/98


occurred with respect to any of them or any such property  that,  with notice or
the passage of time, or both, is reasonably  likely to result in liability under
Environmental  Laws.  Neither  Sterling nor any of its Subsidiaries has received
any notice from any person or entity that  Sterling or its  Subsidiaries  or the
operation or condition of any property ever owned, leased,  operated, or held as
collateral or in a fiduciary capacity by any of them are or were in violation of
or  otherwise  are  alleged  to have  liability  under  any  Environmental  Law,
including, but not limited to, responsibility (or potential  responsibility) for
the cleanup or other remediation of any pollutants,  contaminants,  or hazardous
or toxic wastes,  substances or materials at, on, beneath,  or originating  from
any such property.

                           (P)      Tax Matters.

                              (i)(a) All Tax  Returns  that are  required  to be
filed  (taking into account any  extensions  of time within which to file) by or
with  respect  to  Sterling  and its  Subsidiaries  have been duly filed and the
information therein reported is substantially correct, (b) all Taxes shown to be
due on the Tax Returns referred to in clause (a) have been paid in full, (c) the
federal  income Tax Returns  referred to in clause (a) have been examined by the
IRS or the  period  for  assessment  of the Taxes in  respect  of which such Tax
Returns were required to be filed has expired, (d) all deficiencies  asserted or
assessments made as a result of such examinations have been paid in full, (e) no
issues that have been raised by the relevant taxing authority in connection with
the  examination  of any of the  Tax  Returns  referred  to in  clause  (a)  are
currently pending,  and (f) no waivers of statutes of limitation have been given
by or  requested  with  respect to any Taxes of  Sterling  or its  Subsidiaries.
Sterling has made available to Mason-Dixon true and correct copies of the United
States  federal  income Tax Returns filed by Sterling and its  Subsidiaries  for
each of the three most recent fiscal years ended on or before December 31, 1997.
Neither  Sterling nor any of its  Subsidiaries has any liability with respect to
Taxes that  accrued on or before  December  31,  1997,  in excess of the amounts
accrued with respect thereto that are reflected in the Balance Sheet.

                              (ii) No Tax is required to be withheld pursuant to
Section 1445 of the Code as a result of the Transactions.

                         (Q) Risk  Management  Instruments.  All  interest  rate
swaps, caps, floors, option agreements,  futures and forward contracts and other
similar risk  management  arrangements,  whether entered into for Sterling's own
account,  or for the account of one or more of Sterling's  Subsidiaries or their
customers  (all of which are listed on  Sterling's  Disclosure  Schedule),  were
entered  into  (i)  in  accordance  with  prudent  business  practices  and  all
applicable  laws,  rules,  regulations  and  regulatory  policies  and (ii) with
counterparties  believed to be financially  responsible at the time; and each of
them constitutes the valid and legally binding  obligation of Sterling or one of
its   Subsidiaries,   enforceable  in  accordance  with  its  terms  (except  as
enforceability   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), and
are in full force and effect.  Neither  Sterling  nor its  Subsidiaries,  nor to
Sterling's  knowledge,  any  other  party  thereto,  is in  breach of any of its
obligations under any such agreement or arrangement.

                         (R)  Assets.   Sterling  has  Previously  Disclosed  to
Mason-Dixon a complete and accurate list of all real  property,  leaseholds,  or
other interests therein owned by Sterling and its Subsidiaries. Sterling and its
Subsidiaries  own (with good and marketable  title in the case of real property,
subject  only  to the  matters  permitted  by the  following  sentence)  all the
properties and assets (whether real, personal,  or mixed and whether tangible or
intangible) that they purport to own located in the facilities owned or operated
by Sterling and its  Subsidiaries or reflected as owned in the books and records
of Sterling and its  Subsidiaries,  including all of the  properties  and assets
reflected in the Balance Sheet and the Interim  Balance Sheet (except for assets
held  under  capitalized  leases  Previously  Disclosed  or not  required  to be
disclosed and personal property sold since the date of the Balance Sheet and the
Interim  Balance Sheet, as the case may be, in the Ordinary Course of Business),
and all of the properties and assets purchased or otherwise acquired by Sterling
and its  Subsidiaries  since the date of the Balance  Sheet (except for personal
property  acquired and sold since the date of the Balance  Sheet in the Ordinary
Course of Business).  All property and assets reflected in the Balance Sheet and
the  Interim  Balance  Sheet are free and clear of all Liens and are not, in the
case of real property,  subject to any rights of way, building use restrictions,
exceptions,  variances,  reservations, or limitations of any nature except, with
respect to all such properties and assets,  (i) mortgages or security  interests
shown on the Balance Sheet or the Interim  Balance  Sheet as securing  specified
liabilities  or  obligations,  with  respect to which no default (or event that,
with notice or lapse of time or both, would  constitute a default) exists,  (ii)
mortgages  or security  interests  incurred in  connection  with the purchase of
property or assets after the date of the Interim  Balance Sheet (such  mortgages
and security  interests  being  limited to the property or assets so  acquired),
with respect to which no default (or event that, with notice or lapse of time or
both, would constitute a default) exists,  (iii) Liens for current taxes not yet
due, and (iv) with respect to real property,  (a) minor  imperfections of title,
if any, none of which is  substantial  in amount,  materially  detracts from the
value or  impairs  the use of the  property  subject  thereto,  or  impairs  the
operations of Sterling or any Subsidiary, and (b) zoning laws and other land use
restrictions  that do not impair the present or anticipated  use of the property
subject thereto.

                         (S) Books and  Records.  The books of  account,  minute
books,  stock record books, and other records of Sterling and its  Subsidiaries,
all of which have been made available to  Mason-Dixon,  are complete and correct
and have been  maintained in accordance  with sound  business  practices and the
requirements  of Section  13(b)(2) of the Exchange Act (regardless of whether or
not Sterling and its  Subsidiaries  are subject to that Section),  including the
maintenance  of an adequate  system of internal  controls.  The minute  books of
Sterling and its  Subsidiaries  contain  accurate  and  complete  records of all
meetings held of, and corporate



                                     - 30 -

action taken by, the  stockholders,  the Boards of Directors,  and committees of
the Boards of Directors of Sterling and its Subsidiaries,  and no meeting of any
such  stockholders,  Board of  Directors,  or committee  has been held for which
minutes have not been prepared and are not  contained in such minute  books.  At
the  Closing,  all of those  books  and  records  will be in the  possession  of
Sterling  and its  Subsidiaries.  The  books and  records  of  Sterling  and its
Subsidiaries have been fully, properly and accurately maintained,  and there are
no material  inaccuracies  or  discrepancies  of any kind contained or reflected
therein,  and they fairly  present the  financial  position of Sterling  and its
Subsidiaries.

                         (T)  Insurance.  Sterling's  Disclosure  Schedule  sets
forth all of the insurance policies, binders, or bonds maintained by Sterling or
its  Subsidiaries  ("Insurance  Policies").  Sterling and its  Subsidiaries  are
insured with  reputable  insurers  against such risks and in such amounts as the
management  of Sterling  reasonably  has  determined to be prudent in accordance
with  industry  practices.  All the  Insurance  Policies  are in full  force and
effect;  Sterling and its  Subsidiaries are not in default  thereunder;  and all
claims thereunder have been filed in due and timely fashion.

                         (U) Year 2000. Sterling and the Bank have complied with
all  interagency  statements  issued  through  September 2, 1998, by the Federal
Financial  Institutions   Examination  Council  on  the  subject  of  Year  2000
compliance.  Sterling and the Bank have exercised due care in assessing the Year
2000 compliance status of all material computer software,  firmware and hardware
used  in the  Ordinary  Course  of  Business  and in  assessing  the  Year  2000
compliance  status of their customers and  counterparties.  Neither Sterling nor
its Subsidiaries has received a "Year 2000 Deficiency  Letter" or criticism from
any Governmental Authority on the subject of Year 2000 compliance.  Sterling and
its  Subsidiaries  have taken reasonable steps necessary for the data processing
systems used in the business of Sterling  and its  Subsidiaries  to be Year 2000
Compliant on or before the end of 1999 and  Sterling  does not expect the future
cost of addressing such issues to be material.

                         (V)  Asset  Classification.   Sterling  has  previously
disclosed  a list,  accurate  and  complete  in all  material  respects,  of the
aggregate  amounts of loans,  extensions of credit or other assets of it and its
Subsidiaries  that have been  classified  by it as of  September  30,  1998 (the
"Asset Classification");  and no amounts of loans, extensions of credit or other
assets that have been  classified as of September  30, 1998 by any  Governmental
Authority  as "other  loans  specially  mentioned",  "substandard",  "doubtful",
"loss",  or words of similar  import are excluded from the amounts  disclosed in
the Asset Classification,  other than amounts of loans,  extensions of credit or
other assets that were charged off by it or a Subsidiary  prior to September 30,
1998.

                         (W) No  Brokers.  Except  for fees  payable  to Garland
McPherson &  Associates,  Inc.,  no action has been taken by Sterling that would
give rise to any valid claim

payment with respect to the Transactions.

                         (X)  Disclosure.  The  representations  and  warranties
contained in this Section 5.3 do not contain any untrue  statement of a material
fact  or omit to  state  any  material  fact  necessary  in  order  to make  the
statements and information contained in this Section 5.3 not misleading.

                  5.4 Representations  and Warranties of Mason-Dixon.  Except as

laws of the State of Maryland.  Mason-Dixon,  MDMS and BoM are duly qualified to
do  business  and are in good  standing  in the states of the United  States and
foreign jurisdictions where their respective ownership or leasing of property or
assets  or the  conduct  of their  respective  business  requires  them to be so
qualified.  Mason-Dixon,  MDMS and BoM have in effect all federal, state, local,

properties and assets and to carry on their  respective  businesses as it is now
conducted.  Mason-Dixon and MDMS are registered as bank holding  companies under
the BHC Act. BoM is a trust company under the laws of the State of Maryland.

                         (B)  Subsidiaries.  Each of Mason-Dixon's  Subsidiaries
has been duly organized and is validly  existing in good standing under the laws
of the  jurisdiction of its  organization,  and is duly qualified to do business
and in good  standing in the  jurisdictions  where its  ownership  or leasing of
property or the conduct of its business  requires it to be so  qualified  and it
owns,  directly or indirectly,  all the issued and outstanding equity securities
of each of its Subsidiaries.

                         (C)  Corporate  Power.  Mason-Dixon  and  each  of  its
Subsidiaries  has the corporate  power and authority to carry on its business as
it is now being conducted and to own all its properties and assets;  and each of
Mason-Dixon,  MDMS and BoM has the  corporate  power and  authority  to execute,
deliver  and  perform  its  obligations  under this Plan and to  consummate  the
Transactions.

                         (D) Corporate Authority. This Plan and the Transactions
have been authorized by all necessary  corporate  action of each of Mason-Dixon,
MDMS and BoM. This Plan and the  Transactions are not required to be approved by
the shareholders of Mason-Dixon. The Bank Merger is subject to approval by MDMS,
its sole  stockholder,  and has been approved.  This Plan is a valid and legally
binding agreement of each of Mason-Dixon, MDMS and BoM

enforceable  in  accordance  with its terms  (except  as  enforceability  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).

                           (E)      Regulatory Approvals; No Defaults.

                              (i) No  consents  or  approvals  of, or filings or
registrations  with,  any  Governmental  Authority  or with any third  party are
required to be made or obtained by  Mason-Dixon  or any of its  Subsidiaries  in
connection with the execution,  delivery or performance by Mason-Dixon or any of
its Subsidiaries of this Plan or to consummate the  Transactions  except for (a)
the filing of applications  and notices,  as applicable,  with federal and state
banking  authorities,  receipt of  approval  thereof and  expiration  of related
waiting  periods;  and (b) the filing of articles of share  exchange  and merger
with the SDAT  pursuant to the MGCL. As of the date hereof,  Mason-Dixon  is not
aware of any reason why the  approvals  set forth in Section  7.1(B) will not be
received  without the  imposition of a condition,  restriction or requirement of
the type described in Section 7.1(B).

                              (ii)   Subject  to   receipt  of  the   regulatory
approvals  referred to in the preceding  paragraph and expiration of the related
waiting  periods,  the execution,  delivery and performance of this Plan and the
consummation of the  Transactions do not and will not (a) constitute a breach or
violation of, or a default under, or give rise to any Lien, any  acceleration of
remedies or any right of termination  under,  any law, rule or regulation or any
judgment,  decree,  order,  governmental  permit  or  license,  or  Contract  of
Mason-Dixon or of any of its Subsidiaries or to which  Mason-Dixon or any of its
Subsidiaries  or  properties  is subject or bound,  (b)  constitute  a breach or
violation of, or a default under,  the articles of  incorporation or by-laws (or
similar governing  documents) of Mason-Dixon or any of its Subsidiaries,  or (c)
require any consent or approval under any such law, rule, regulation,  judgment,
decree, order, governmental permit or license, or Contract.

                         (F) No Brokers. No action has been taken by Mason-Dixon
that would give rise to any valid claim against any party hereto for a brokerage
commission, finder's fee or other like payment with respect to the Transactions.

                         (G) Financial  Capacity.  Mason-Dixon has the financial
capacity to fund the cash payments for the Share Exchange  Consideration and for
cancellation of the Sterling Stock Options.  Based upon  Mason-Dixon's pro forma
financial  analysis,  immediately  following  consummation of the  Transactions,
Mason-Dixon,  MDMS,  and BoM each  will  continue  to be  "well-capitalized"  as
defined in the  appropriate  capital  regulation  and  guidance  of its  primary
federal regulator.

                         (H) Financial Statements.

                              (i)  Mason-Dixon  has filed and made  available to
Sterling  accurate  and complete  copies of all forms,  reports,  and  documents
required  to be filed by Mason-  Dixon  with the SEC since  December  31,  1994,
(collectively,  the "Mason-Dixon SEC Reports").  The Mason-Dixon SEC Reports (a)
at the time  filed,  complied  in all  material  respects  with  the  applicable
requirements of the Securities Act and the Exchange Act, as the case may be, and
(b) did not at the time they were filed (or if amended or superseded by a filing
prior to the date of this  Agreement,  then on the date of such filing)  contain
any  untrue  statement  of a  material  fact or omit to  state a  material  fact
required to be stated in such  Mason-Dixon  SEC Reports or necessary in order to
make  the  statements  in  the  Mason-Dixon   SEC  Reports,   in  light  of  the
circumstances under which they were made, not misleading. Except for Mason-Dixon
Subsidiaries that are registered as brokers,  dealers,  investment advisors,  or
associated persons thereof, none of the Mason-Dixon  Subsidiaries is required to
file any forms, reports or other documents with the SEC.

                              (ii) Each of the Mason-Dixon  Financial Statements
(including,  in each case, any related notes)  contained in the  Mason-Dixon SEC
Reports,  complied,  and each SEC Report filed after the date of this  Agreement
until the Effective Time will comply,  as to form in all material  respects with
the applicable  published rules and regulations of the SEC with respect thereto,
was prepared in accordance  with GAAP applied on a consistent  basis  throughout
the periods  involved (except as may be indicated in the notes to such financial
statements or, in the case of unaudited statements, as permitted by Form 10-Q of
the  SEC),  and  fairly  presented  the  consolidated   financial   position  of
Mason-Dixon and its Subsidiaries as at the respective dates and the consolidated
results of its operations and cash flows for the periods indicated,  except that
the unaudited  interim  financial  statements  were or are subject to normal and
recurring year-end adjustments which were not or are not expected to be material
in amount.

                         (I)  Disclosure.  The  representations  and  warranties
contained in this Section 5.4 do not contain any untrue  statement of a material
fact  or omit to  state  any  material  fact  necessary  in  order  to make  the
statements and information contained in this Section 5.4 not misleading.

                                    COVENANTS

                  6.1  Reasonable  Best  Efforts.   Subject  to  the  terms  and
conditions of this Plan, each of Sterling, the Bank,  Mason-Dixon,  MDMS and BoM
agrees to use its reasonable  best efforts in good faith to take, or cause to be
taken, all actions, and to do, or cause to be done, all things necessary, proper
or desirable,  or advisable under applicable laws, so as to permit  consummation
of  the  Transactions  as  promptly  as  practicable  and  otherwise  to  enable
consummation  of the  Transactions  and  shall  cooperate  fully  with the other
parties hereto to that

end. Except as expressly  contemplated or permitted by this Plan, or as required
by applicable  law, rule or regulation,  during the period from the date of this
Plan to the  Effective  Time,  Mason- Dixon  shall,  and shall cause each of its
Subsidiaries  to, take no action which would reasonably be expected to adversely
affect or delay the ability of Mason-Dixon,  Sterling,  MDMS, the Bank or BoM to
obtain any approvals of any  Governmental  Authority  required to consummate the
Transactions  or to perform its covenants and  agreements  herein.  Prior to the
Effective  Time,  Sterling shall acquire all of the  outstanding  shares of Bank
common stock which it does not own.

                  6.2  Stockholder  Approval.   Subject  to  compliance  by  the
Sterling Board with its fiduciary duties, Sterling agrees to take, in accordance
with applicable law, and its articles of incorporation  and by-laws,  all action
necessary to convene an appropriate  meeting of its stockholders to consider and
vote upon the approval and adoption of this Plan and any other matters  required
to be approved by Sterling's  stockholders  for consummation of the Transactions
(including any adjournment or postponement, the "Sterling Meeting"), as promptly
as practicable  after the date hereof.  Sterling  shall use its reasonable  best
efforts to mail the notice of the Sterling Meeting within 30 days after the date
hereof.  Subject to compliance  with its fiduciary  duties,  the Sterling  Board
shall recommend such approval,  and shall cause Sterling to take all reasonable,
lawful action to solicit such approval by its  stockholders.  Mason-Dixon  shall
have the right to review in  advance  the proxy  statement,  and any  amendments
thereto, to be delivered to Sterling's stockholders with respect to the Sterling
Meeting. The proxy statement, and any amendments thereto, shall not be delivered
to Sterling's  stockholders  without  Mason-Dixon's prior written approval which
shall not be unreasonably withheld.

                  6.3 Press Releases.  Each of Sterling and  Mason-Dixon  agrees
that it will not,  nor will it permit its  Subsidiaries  to,  without  the prior
approval of the other party,  issue any press  release or written  statement for
general circulation  relating to the Transactions,  except as otherwise required
by applicable law or regulation or NASD rules.

                  6.4      Access; Information.

                         (A) Each of  Sterling  and the Bank  agrees  that  upon
reasonable  notice and subject to  applicable  laws  relating to the exchange of
information, it shall afford Mason- Dixon and Mason-Dixon's officers, employees,
counsel,  accountants and other authorized  representatives,  such access during
normal  business hours  throughout the period prior to the Effective Time to the
books,  records (including,  without limitation,  tax returns and work papers of
independent auditors,  but only upon the consent of such auditors),  properties,
personnel and to such other  information as Mason-Dixon  may reasonably  request
and, during such period,  it shall furnish promptly to Mason-Dixon (i) a copy of
each  report,   schedule  and  other  document  filed  by  it  pursuant  to  the
requirements of federal or state  securities or banking laws, and (ii) all other
information concerning the business, properties and personnel of it as the other
may reasonably request.

                         (B) Mason-Dixon agrees that it will not, and will cause
its  Representatives  not to,  use any  information  obtained  pursuant  to this
Section 6.4 (as well as any other information  obtained prior to the date hereof
in connection with the entering into of this Plan) for any purpose  unrelated to
the  consummation  of the  Transactions.  Subject  to the  requirements  of law,
Mason-Dixon will keep confidential,  and will cause its  Representatives to keep
confidential,  all information and documents  obtained  pursuant to this Section
6.4 (as well as any  other  information  obtained  prior to the date  hereof  in
connection with the entering into of this Plan) unless such  information (i) was
already  known to such party,  (ii)  becomes  available to such party from other
sources  not known by such  party to be bound by a  confidentiality  obligation,
(iii) is disclosed  with the prior  written  approval of the party to which such
information pertains or (iv) is or becomes readily  ascertainable from published
information or trade  sources.  In the event that this Plan is terminated or the
Transactions shall otherwise fail to be consummated,  Mason-Dixon shall promptly
cause all copies of documents or extracts  thereof  containing  information  and
data as to another party hereto to be returned to the party which  furnished the
same.

                         (C) No  investigation  by either  party of the business
and  affairs  of the  other  shall  affect  or be  deemed to modify or waive any
representation,  warranty, covenant or agreement in this Plan, or the conditions
to either party's obligation to consummate the Transactions.

                    6.5   Certain    Modifications;    Restructuring    Charges;
Observation Rights; Month End Financials.

                         (A)  Sterling  shall  consult  with   Mason-Dixon  with
respect to its loan, litigation and real estate valuation policies and practices
(including loan  classifications and levels of reserves) and Sterling shall make
such  modifications or changes to its policies and practices,  if any, as may be
mutually agreed upon in order to conform such policies and practices to those of
Mason-Dixon or due to differing disposition plans of Mason-Dixon. Sterling shall
also consult with Mason-Dixon  with respect to the character,  amount and timing
of  restructuring  charges  to be  taken  by  Sterling  in  connection  with the
Transactions  and shall take such  charges in  accordance  with GAAP,  as may be
mutually  agreed upon.  Such  modifications  and changes  shall be made and such
charges  taken at such date prior to the  Effective  Time as the  parties  shall
mutually agree,  but no earlier than the date  Mason-Dixon  advises  Sterling in
writing  that  all of the  conditions  precedent  to  Mason-Dixon's  obligations
hereunder  either have been  satisfied  or waived.  No party's  representations,
warranties and covenants  contained in this Plan shall be deemed to be untrue or
breached in any respect for any purpose as a consequence of any modifications or
changes to such  policies and  practices  which may be  undertaken on account of
this Section 6.5.

                         (B) During the period from the date of this Plan to the
Effective Time, an individual  designated by Mason-Dixon shall have the right to
attend all meetings of the Sterling Board and the board of directors of the Bank
in a nonvoting  observer  capacity,  other than any part of any meeting at which
this Plan or the Transactions or any other  Acquisition  Proposal are discussed,
to receive  notice of such meetings and to receive the  information  provided by
Sterling and the Bank to their respective boards of directors.

                         (C) During the period from the date of this Plan to the
Effective Time, Sterling shall prepare  consolidated  balance sheets of Sterling
and its Subsidiaries, and the related consolidated statements of operations, and
changes in  stockholders'  equity as of the last day of each month  prior to the
15th day of the following month, provided, however, that the foregoing financial
reports shall be prepared for the month preceding the Effective Date on or prior
to the 8th day of the following month.

                  6.6      Regulatory Applications.

                         (A)  Mason-Dixon  and  Sterling  and  their  respective
Subsidiaries shall cooperate and use their respective reasonable best efforts to
prepare all  documentation,  to effect all  filings  and to obtain all  permits,
consents,  approvals and  authorizations  of all third parties and  Governmental
Authorities necessary to consummate the Transactions.  Mason-Dixon shall use its
reasonable best efforts to file  applications with the Federal Reserve Board and
the Maryland  Commissioner of Financial Regulation within 30 days after the date
hereof.  Each of Mason-  Dixon and  Sterling  shall  have the right to review in
advance, and to the extent practicable each will consult with the other, in each
case subject to applicable  laws relating to the exchange of  information,  with
respect  to  all  written  information  submitted  to  any  third  party  or any
Governmental  Authority in connection with the  Transactions.  In exercising the
foregoing  right,  each of the parties  hereto agrees to act  reasonably  and as
promptly as practicable.  Each party hereto agrees that it will consult with the

to  completion  of the  Transactions.  Each party  hereto  agrees  that it shall
deliver to the other promptly upon receipt copies of all correspondence from and
to Governmental Authorities relating to the Transactions.

                         (B) Each party  agrees,  upon  request,  to furnish the
other  party with all  information  concerning  itself,  its  Subsidiaries,  its
Representatives  and  stockholders  and such other  matters as may be reasonably
necessary or advisable in connection with any filing, notice or application made
by or on  behalf of such  other  party or any of its  Subsidiaries  to any third
party or  Governmental  Authority and with respect to the proxy  statement to be
delivered to Sterling's stockholders with respect to the Sterling Meeting.

                  6.7      Indemnification.

                         (A) Following the Effective  Date and for a period of 6
years thereafter,  MDMS shall indemnify,  defend and hold harmless the Directors
and officers of Sterling and its  Subsidiaries  (each, an  "Indemnified  Party")
against all costs or expenses (including reasonable attorneys' fees), judgments,
fines,  losses,  claims,  damages or  liabilities  or amounts paid in settlement
(collectively,  "Costs")  incurred in connection with any claim,  action,  suit,
proceeding  or  investigation,   whether  civil,  criminal,   administrative  or
investigative,  (collectively,  "Claims")  arising  out of actions or  omissions
occurring at or prior to the Effective Time, including,  but not limited to, the
Transactions,  regardless of whether such claim is asserted before,  at or after
the Effective  Time, to the fullest extent that Sterling or its  Subsidiaries is
permitted to  indemnify  (and advance  expenses to) its  directors  and officers
under  the laws of the State of  Maryland,  the  articles  of  incorporation  or
by-laws of Sterling  or its  Subsidiaries  all as in effect on the date  hereof,
except as such  indemnification  (and  advancement of expenses) may be waived or
released  by an  Indemnified  Party;  provided  that for Claims  covered by this
Section 6.7(A), any determination required to be made with respect to whether an
officer's or  director's  conduct  complies  with the  standards set forth under
Maryland  law,  the  articles  of  incorporation  or by-laws of  Sterling or its
Subsidiaries  shall be made by  independent  counsel (which shall not be counsel
that provides  material  services to  Mason-Dixon)  selected by Mason-Dixon  and
reasonably acceptable to such officer or director;  and provided,  further, that
in the absence of applicable  Maryland judicial precedent to the contrary,  such
counsel,  in  making  such  determination,   shall  presume  such  officer's  or
director's conduct complied with such standard and MDMS shall have the burden to
demonstrate that such officer's or director's conduct failed to comply with such
standard.  To the extent a Claim is asserted  before the  Effective  Time,  MDMS
shall have no obligations under this Section unless appropriate notice was given
to  Sterling's  director's  and officer's  liability  insurer as required by the
insurance policy prior to the Effective Time.

                         (B) For a period of 6 years  from the  Effective  Time,
MDMS either shall permit  Sterling to purchase a "tail" coverage on its existing
directors and officers insurance policy or shall use its reasonable best efforts
to provide that portion of director's  and officer's  liability  insurance  that
serves to reimburse the present and former officers and Directors of Sterling or
any of its  Subsidiaries  (determined as of the Effective  Time) with respect to
Claims  against such  Directors and officers  arising from facts or events which
occurred before the Effective  Time,  which insurance shall contain at least the
same  coverage  and  amounts,   and  contain   terms  and   conditions  no  less
advantageous,  as  that  coverage  currently  provided  by  Sterling;  provided,
however, that in no event shall MDMS be required to expend more than 200 percent
of the current amount expended by Sterling or its  Subsidiaries  (the "Insurance
Amount") to maintain or procure such directors and officers  insurance  coverage
for a comparable  6-year period;  provided,  further,  that if MDMS is unable to
maintain or obtain the insurance  called for by this Section 6.7(B),  MDMS shall
use its  reasonable  best efforts to obtain as much  comparable  insurance as is
available  for the  Insurance  Amount;  provided,  further,  that  officers  and
Directors of Sterling



                                     - 38 -

2:10/16/98


or any  Subsidiary  may be required to make  application  and provide  customary
representations  and warranties to MDMS's  insurance  carrier for the purpose of
obtaining such insurance.

                         (C)   Any   Indemnified    Party   wishing   to   claim
indemnification  under Section 6.7(A), upon learning of any Claim shall promptly
notify MDMS thereof; provided that the failure so to notify shall not affect the
obligations  of MDMS under Section  6.7(A) unless and to the extent that MDMS is
actually prejudiced as a result of such failure.

                         (D) The  obligations  of MDMS  pursuant to this Section
6.7 may be enforced directly by the Indemnified Parties.

                         (E) If MDMS or any of its  successors  or assigns shall
consolidate  with or merge into any other entity and shall not be the continuing
or surviving  entity of such  consolidation  or merger or shall  transfer all or
substantially  all of its  assets to any other  entity,  then and in each  case,
proper  provision shall be made so that the successors and assigns of MDMS shall
assume the obligations set forth in this Section 6.7.

                  6.8  Notification  of Certain  Matters.  Each of Sterling  and
Mason-Dixon  shall  give  prompt  notice  to the  other  of any  fact,  event or
circumstance  known to it that (A) is reasonably  likely,  individually or taken
together with all other facts,  events and circumstances  known to it, to result
in any  Material  Adverse  Effect  with  respect  to it or (B)  would  cause  or
constitute  a  material  breach  of  any  of  its  representations,  warranties,
covenants or agreements contained herein.

                  6.9 No  Solicitation.  From the date of this  Plan  until  the
Effective Time or the  termination of this Plan pursuant to its terms,  Sterling
agrees that it will not, and will not permit any of its Subsidiaries,  or any of
its or their Representatives to, directly or indirectly, (A) initiate,  solicit,
encourage or otherwise facilitate (including by way of furnishing  information),
any  inquiries or the making of any proposal or offer that  constitutes,  or may
reasonably be expected to lead to, an Acquisition Proposal, or (B) enter into or
maintain or continue  discussions or negotiate with any Person in furtherance of
such inquiries or to obtain an Acquisition  Proposal,  or (C) agree to, approve,
recommend,  or endorse any Acquisition  Proposal,  or authorize or permit any of
its or their Subsidiaries or Representatives to take any such action and, except
to the  extent  prohibited  by  contracts  existing  at the  date of this  Plan,
Sterling shall  promptly  notify Mason- Dixon of any such inquiries of proposals
received by Sterling or any of its Subsidiaries or  Representatives  relating to
any of such  matters;  provided,  however,  that nothing  contained in this Plan
shall  prohibit  the  Sterling  Board  from (i)  furnishing  information  to, or
engaging  in  discussions  or  negotiations  with,  any Person in response to an
unsolicited bona fide written Acquisition Proposal; or (ii) recommending such an
unsolicited  bona fide  written  Acquisition  Proposal  to the  stockholders  of
Sterling,  if and only to the extent that (a) the  Sterling  Board  concludes in
good  faith  (after   consultation  with  its  financial   advisors)  that  such
Acquisition



                                     - 39 -

<PAGE>


F5856N.597 Y
2:10/16/98


Proposal  would  constitute  a  Superior  Proposal  and (b) the  Sterling  Board
determines in good faith (after  consultation  with outside legal  counsel) that
the failure to take such action would  result in a breach by the Sterling  Board
of its fiduciary duties to Sterling's stockholders under applicable law, and (c)
prior to  furnishing  such  information  to, or  entering  into  discussions  or
negotiations  with,  such Person,  Sterling  provides  prompt  written notice to
Mason-Dixon to the effect that it is furnishing information to, or entering into
discussions or  negotiations  with, such Person (which notice shall identify the
nature and  material  terms of the  proposal),  and (d) prior to  providing  any
information or data to any Person in connection with an Acquisition  Proposal by
any such  Person,  the  Sterling  Board  receives  from such  Person an executed
confidentiality agreement with provisions no less favorable to Sterling than the
confidentiality   agreement   previously   entered  into  between  Sterling  and
Mason-Dixon in connection with their consideration of the Transactions. Sterling
agrees that it will  immediately  cease and cause to be terminated  any existing
activities,   discussions,  or  negotiations  with  any  parties  regarding  any
Acquisition  Proposal.  Sterling  agrees to keep  Mason-Dixon  fully and  timely
informed  of  the  status  of  any  discussions,   negotiations,  furnishing  of
non-public information, or other activities relating to an Acquisition Proposal.

                  6.10     Employee Benefits.

                         (A)   Sterling   and  the  Bank  agree   that   neither
Mason-Dixon nor any of its  Subsidiaries is under any obligation to continue the
employment  of any  employee of Sterling or the Bank after the  Effective  Date.
Mason-Dixon  and its  Subsidiaries  may  terminate  the  employment  of any such
employee in their discretion.

                         (B) The Bank agrees to amend the Sterling  Bank & Trust
Company  Change-In-Control  Protection Plan (as originally adopted as of May 19,
1998 and as amended  pursuant to this Section,  the "Protection  Plan") prior to
the  Effective  Date to provide that no severance  benefit  shall be paid to any
Person  unless  that  Person  executes a  "Release  and  Agreement"  in the form
previously agreed to by Mason-Dixon. The Bank agrees to make no other amendments
to the Protection Plan, and warrants that no other amendments have been made.

                         (C) (i) Until 90 days  after the first  anniversary  of
the  Effective  Date,  Mason-Dixon  agrees to continue in effect the  Protection
Plan, but only for the benefit of those 4 persons  originally named as Executive
Officers in Section 1.10 of the  Protection  Plan.  Sterling and the Bank hereby
warrant that no other persons are identified as Executive Officers under Section
1.10 and agree not to identify  any other  persons as Executive  Officers  under
Section 1.10.

                              (ii)  Subject  to  Section  6.10(D),   Mason-Dixon
agrees to pay (or cause to be paid) a severance  benefit  equal to 3 months base
salary to any person who was a full time  employee of the Bank on the day before
the  Effective  Date  and  whose   employment   with  the  Continuing   Bank  is
involuntarily terminated during the 120 day period following the effective

date of the Bank Merger. The payment  obligation under this Section  6.10(C)(ii)
will not apply to: (a) the 4 persons who are covered by the Protection Plan, (b)
any employee who is  terminated  for "Just Cause" as that term is defined in the
Protection  Plan and as determined by Mason-  Dixon,  or (c) any employee  whose
most recent date of hire by the Bank is after October 1, 1998.

                              (iii) On the Effective Date, Mason-Dixon agrees to
pay a  retention  bonus  to such of the  Sterling  employees  as  determined  by
Sterling  after  consultation  with  Mason-Dixon  in an aggregate  amount not to
exceed  $75,000,  provided  that no  bonus  will be  paid  to any  person  whose
employment with the Bank terminates for any reason before the Effective Date.

                         (D)  Mason-Dixon  has no  obligation to pay a severance
benefit under Section  6.10(C)(ii)  to any person unless that person  executes a
"Release and Agreement" in the form previously agreed to by Mason-Dixon.

                         (E) At  Mason-Dixon's  option,  the Bank  shall pay the
foregoing  severance benefits and retention bonuses on the Effective Date, prior
to the Effective Time.

                         (F) Except as provided in Section 6.10(C),  Mason-Dixon
and its  Subsidiaries  are under no obligation to continue any fringe benefit or
employee  benefit  plan or practice of  Sterling or its  Subsidiaries  after the
Effective Date.

                         (G) (i) Following the Effective Time, Mason-Dixon shall
provide generally to officers and employees of Sterling and its Subsidiaries who
continue to be  employed  by  Mason-Dixon  or any of its  Subsidiaries  employee
benefits under employee  benefit plans of  Mason-Dixon  or its  Subsidiaries  on
terms and  conditions  which are no less  favorable  than those then provided by
Mason-Dixon  and its  Subsidiaries  to their  similarly  situated  officers  and
employees, except as otherwise expressly set forth in this Plan.

                              (ii) For  purposes  of  participation  and vesting
(but not benefit  accrual) under any employee  benefit plans of Mason-Dixon  and
its  Subsidiaries,  service by the  employees of Sterling  and its  Subsidiaries

                                    EXHIBIT A


Ladies and Gentlemen:

We have acted as counsel to Mason-Dixon Bancorp,  Inc.,  Mason-Dixon Merger Sub,
Inc., and Bank of Maryland (collectively,  "Mason-Dixon") in connection with the
Agreement and Plan of Share Exchange and Mergers dated  ____________,  1998 (the
"Plan") between Mason-Dixon and Sterling Bancorp and Sterling Bank and Trust Co.
(collectively "Sterling"). This is the opinion contemplated by Section 7.2(D) of
the Plan. All capitalized terms used in this opinion without definition have the
respective meanings given to them in the Plan or the Accord referred to below.

This Opinion Letter is governed by, and shall be interpreted in accordance with,
the Legal  Opinion  Accord (the  "Accord")  of the ABA  Section of Business  Law
(1991).  As a  consequence,  it  is  subject  to  a  number  of  qualifications,
exceptions,  definitions,  limitations on coverage and other limitations, all as
more  particularly  described in the Accord,  and this Opinion  Letter should be
read in conjunction therewith.  The law covered by the opinions expressed herein
is limited to the Federal  Law of the United  States and the Law of the State of
Maryland.

Based on the foregoing, our opinion is as follows:

1. Assuming due  authorization of the Plan by Sterling and the Bank, the Plan is
enforceable  against  Mason-Dixon,  MDMS and BoM in  accordance  with its terms,
except that enforcement against Mason-Dixon,  MDMS and BoM may be limited by (a)
bankruptcy, insolvency, moratorium, reorganization or similar laws effecting the
rights of creditors  generally,  (b) equitable  principles limiting the right to
specific performance or other similar equitable relief, or (c) considerations of
public policy.

2.  Neither  the  execution  and  delivery  of the Plan nor the  performance  of
Mason-Dixon's, MDMS' and BoM's obligations thereunder (a) violates any provision
of the certificate of incorporation or bylaws (or other governing instrument) of
Mason-Dixon,  MDMS or BoM or (b) violates any statute,  law, regulation or rule,
or any  judgment,  decree  or  order  of any  court  or  Governmental  Authority
applicable to Mason-Dixon, MDMS or BoM.

3. Except for approval by the Maryland Commissioner of Financial Regulation, the
Federal Reserve Board, and the FDIC, no consent,  approval or authorization  of,
or  declaration,  filing or  registration  with, any  Governmental  Authority is
required in connection with the execution,  delivery and performance of the Plan
or the consummation of the Transactions.

To our  actual  knowledge,  there is no  proceeding  by or  before  any court or
Governmental  Authority  pending or  overtly  threatened  against  or  involving
Mason-Dixon,  MDMS or BoM that  questions or challenges the validity of the Plan
or any action taken or to be taken by Mason- Dixon,  MDMS or BoM pursuant to the
Plan or in connection with the Transactions, and to our actual knowledge neither
Mason-Dixon,  MDMS or BoM is subject  to any  judgment,  order or decree  having
prospective effect.

The acquisition will add approximately $77 million in total assets,  $70 million
in deposits,  and $45 million in loans.  Plans call for the merger of Sterling's
principal  subsidiary,  Sterling  Bank & Trust Co.  into  Mason-Dixon's  Bank of
Maryland  subsidiary on or about  February 16, 1999.  Upon the completion of the
bank  merger,  Sterling's  bank  branches  located  in  downtown  Baltimore  and
Pikesville  will be consolidated  with nearby branches of Bank of Maryland.  Its
two other  branches  located in  Timonium  and  Annapolis  will  remain  open as
branches  of  Bank  of  Maryland.  With  the  completion  of  the  bank  merger,
Mason-Dixon will operate 21 banking offices in the Central Maryland region.

Mason-Dixon is a $1.2 billion bank holding company headquartered in Westminster,
Maryland.  It is the parent  company of Carroll  County Bank and Trust  Company,
Bank of Maryland, and Rose Shanis Financial Services, LLC.
