                                   BACKGROUND

                  WHEREAS,  Valley and  Merchants,  as of the date  hereof,  are
prepared  to execute a  definitive  agreement  and plan of merger  (the  "Merger
Agreement") pursuant to which Merchants will be merged with and into Valley (the
"Merger"); and

                  WHEREAS, Valley has advised Merchants that it will not execute
the Merger Agreement unless Merchants executes this Agreement; and

                  WHEREAS,  the Board of Directors of Merchants  has  determined
that the Merger Agreement provides  substantial  benefits to the shareholders of
Merchants; and

                  WHEREAS,  as an  inducement to Valley to enter into the Merger
Agreement and in  consideration  for such entry,  Merchants  desires to grant to
Valley an option to purchase  authorized but unissued  shares of common stock of
Merchants in an amount and on the terms and conditions hereinafter set forth.

                                    AGREEMENT

                  In consideration of the foregoing and the mutual covenants and
agreements set forth herein and in the Merger  Agreement,  Valley and Merchants,
intending to be legally bound hereby, agree:

1.  Grant of Option.  Merchants  hereby  grants to Valley an option to  purchase
4,663,741 shares of common stock,  $0.001 par value per share, of Merchants (the
"Common  Stock")  at a price of $16.98  per share (as the same may be reduced in
accordance  with  Section  5b  hereof,  the  "Option  Price"),  on the terms and
conditions set forth herein (the "Option").

2. Exercise of Option. This Option shall not be exercisable until the occurrence
of a Triggering Event (as such term is hereinafter  defined).  Upon or after the
occurrence of a Triggering Event (as such term is hereinafter  defined),  Valley
may exercise the Option,  in whole or in part, at any time or from time to time,
subject  to the  terms  and  conditions  set forth  herein  and the  termination
provisions of Section 19 of this Agreement.

                  The term "Triggering Event" means the occurrence of any of the
following events:

a. A person or group (as such terms are defined in the  Securities  Exchange Act
of 1934,  as  amended  (the  "Exchange  Act"),  and the  rules  and  regulations
thereunder)  other  than  Valley or an  affiliate  of  Valley (a "third  party")
acquires  beneficial  ownership  (as  such  term is  defined  in Rule  13d-3  as
promulgated  under the  Exchange  Act) of at least  10% of the then  outstanding
shares of Common Stock,  provided,  however,  that the continuing ownership by a
person  or  group  which  as of  the  date  hereof  owns  more  than  10% of the
outstanding Common Stock shall not constitute a Triggering Event; or

b. A third party enters into a letter of intent or an agreement, whether oral or
written,  with Merchants  pursuant to which such third party or any affiliate of
such third  party  would (i) merge or  consolidate,  or enter  into any  similar
transaction,  with Merchants,  (ii) acquire all or a significant  portion of the
assets or liabilities  of Merchants,  or (iii) acquire  beneficial  ownership of
securities representing, or the right to acquire beneficial ownership or to vote
securities  representing,  10% or more of the then outstanding  shares of Common
Stock; or

c. A third  party  makes a filing  with any bank,  thrift or  financial  holding
company regulatory authorities with respect to or publicly announces a bona fide
proposal  (a  "Proposal")  for  (i)  any  merger  with,  consolidation  with  or
acquisition of all or a significant portion of all the assets or liabilities of,
Merchants  or any other  business  combination  involving  Merchants,  or (ii) a
transaction  involving  the  transfer  of  beneficial  ownership  of  securities
representing, or the right to acquire beneficial ownership or to vote securities
representing,  10% or more of the  outstanding  shares of Common  Stock,  and in
either case  thereafter,  if such Proposal has not been  Publicly  Withdrawn (as
such term is  hereinafter  defined)  at least 15 days  prior to the  meeting  of
stockholders  of  Merchants   called  to  vote  on  the  Merger  and  Merchants'
stockholders  fail to approve the Merger by the vote required by applicable  law
at the meeting of stockholders called for such purpose; or

d. A third  party makes a bona fide  Proposal  and  thereafter,  but before such
Proposal has been Publicly Withdrawn, Merchants willfully or intentionally takes
any action in any manner which would  materially  interfere  with its ability to
consummate  the  Merger or  materially  reduce the value of the  transaction  to
Valley; or

e. After the  execution of this  Agreement,  Merchants or any of its  directors,
senior  executive  officers,  investment  bankers or other person with actual or
apparent   authority  to  speak  for  the  Board  of  Directors,   willfully  or
intentionally takes any material direct or indirect action inviting, encouraging
or  soliciting  any proposal  (other than from Valley or an affiliate of Valley)
which has as its  purpose  a tender  offer for the  shares  of Common  Stock,  a
merger,  consolidation,  plan of exchange, plan of acquisition or reorganization
of Merchants, or a sale of a significant number of shares of Common Stock or any
significant portion of its assets or liabilities.

                  The term  "significant  portion"  means  10% of the  assets or
liabilities  of  Merchants.  The  term  "significant  number"  means  10% of the
outstanding shares of Common Stock.

                  Solely  for  purposes  of  Section  5b  hereof,  the date of a
"Triggering  Event"  under  clause (a) above is the date the third  party  first
acquires beneficial  ownership of at least 10% of the then outstanding shares of
Common  Stock;  the date of a  "Triggering  Event" under clause (b) above is the
date of entry into the letter of intent or agreement;  the date of a "Triggering
Event"  under clause (c) above is the earlier of the date of the filing (if any)
with a bank,  thrift or financial  holding  company  regulatory  authority  with
respect to the Proposal or the date of public announcement of the Proposal;  the
date of a "Triggering  Event" under clause (d) above is the date the third party
first makes the Proposal;  and the date of a "Triggering Event" under clause (e)
above is the first date on which a material  direct or indirect  action referred
to therein is taken.

                  "Publicly  Withdrawn",  for  purposes  of clauses  (c) and (d)
above,  shall mean an unconditional bona fide withdrawal of the Proposal coupled
with a public  announcement of no further  interest in pursuing such Proposal or
in acquiring  any  controlling  influence  over  Merchants or in  soliciting  or
inducing any other person (other than Valley or any affiliate) to do so.

                  Notwithstanding the foregoing, the Option may not be exercised
at any  time (i) in the  absence  of any  required  governmental  or  regulatory
approval or consent  (including any filing,  approval or consent  required under
the rules and regulations of any securities exchange or the National Association
of  Securities  Dealers,  Inc.)  necessary  for Merchants to issue the shares of
Common Stock  covered by the Option (the "Option  Shares") or Valley to exercise
the Option or prior to the  expiration  or  termination  of any  waiting  period
required by law, or (ii) so long as any  injunction  or other  order,  decree or
ruling  issued by any federal or state  court of  competent  jurisdiction  is in
effect which prohibits the sale or delivery of the Option Shares.

                  Merchants  shall  notify  Valley  promptly  in  writing of the
occurrence of any  Triggering  Event known to it, it being  understood  that the
giving of such  notice by  Merchants  shall not be a  condition  to the right of
Valley to exercise  the Option.  Merchants  will not take any action which would
have the effect of preventing or disabling  Merchants from delivering the Option
Shares  to Valley  upon  exercise  of the  Option or  otherwise  performing  its
obligations  under this  Agreement,  except to the extent required by applicable
securities and banking laws and regulations.

                  In the event  Valley  wishes to exercise  the  Option,  Valley
shall  send a written  notice  to  Merchants  (the date of which is  hereinafter
referred to as the "Notice  Date")  specifying the total number of Option Shares
it wishes to purchase  and a place and date  between two and ten  business  days
inclusive from the Notice Date for the closing of such a purchase (a "Closing");
provided,  however,  that a Closing  shall not occur prior to two days after the
later of receipt of any necessary regulatory approvals and the expiration of any
legally required notice or waiting period, if any.

3. Payment and Delivery of  Certificates.  At any Closing  hereunder  (a) Valley
will make payment to Merchants of the  aggregate  price for the Option Shares so
purchased  by  wire  transfer  of  immediately  available  funds  to an  account
designated  by  Merchants;   (b)  Merchants  will  deliver  to  Valley  a  stock
certificate  or  certificates  representing  the  number  of  Option  Shares  so
purchased,  free and clear of all liens, claims, charges and encumbrances of any
kind or nature  whatsoever  created by or through  Merchants,  registered in the
name of Valley or its  designee,  in such  denominations  as were  specified  by
Valley in its notice of  exercise  and,  if  necessary,  bearing a legend as set
forth below;  and (c) Valley  shall pay any transfer or other taxes  required by
reason of the issuance of the Option Shares so purchased.

                  If  required  under  applicable  federal  securities  laws  as
determined  by  Merchants'  counsel,  a  legend  will be  placed  on each  stock
certificate  evidencing  Option Shares issued pursuant to this Agreement,  which
legend will read substantially as follows:

         The  shares  of  stock  evidenced  by this  certificate  have  not been
         registered  for sale under the Securities Act of 1933 (the "1933 Act").
         These  shares may not be sold,  transferred  or  otherwise  disposed of
         unless a registration statement with respect to the sale of such shares
         has been filed  under the 1933 Act and  declared  effective  or, in the
         opinion of counsel  reasonably  acceptable to Merchants,  said transfer
         would be exempt from registration  under the provisions of the 1933 Act
         and the regulations promulgated thereunder.

No such  legend  shall be  required  if a  registration  statement  is filed and
declared effective under Section 4 hereof.

4. Registration  Rights.  Upon or after the occurrence of a Triggering Event and
upon receipt of a written request from Valley, Merchants shall, if necessary for
the  resale of the Option or the Option  Shares by  Valley,  prepare  and file a
registration statement with the Securities and Exchange Commission and any state
securities bureau covering the Option and such number of Option Shares as Valley
shall specify in its request,  and Merchants shall use its best efforts to cause
such registration statement to be declared effective in order to permit the sale
or other  disposition of the Option and the Option Shares,  provided that Valley
shall  in no event  have  the  right  to have  more  than one such  registration
statement  become  effective,  and provided  further that Merchants shall not be
required to prepare and file any such registration  statement in connection with
any  proposed  sale with  respect to which  counsel  to  Merchants  delivers  to
Merchants and to Valley  (which is reasonably  acceptable to Valley) its opinion
to the  effect  that no such  filing  is  required  under  applicable  laws  and
regulations  with respect to such sale or disposition or any subsequent  sale or
disposition;   provided   further,   however,   that  Merchants  may  delay  any
registration  of Option  Shares above for a period not  exceeding 90 days in the
event that Merchants  shall in good faith  determine that any such  registration
would adversely effect an on-going offering of securities by Merchants for cash.
Valley shall  provide all  information  reasonable  requested  by Merchants  for
inclusion in any registration statement to be filed hereunder.

                  In connection  with such filing,  Merchants shall use its best
efforts  to  cause  to be  delivered  to  Valley  such  certificates,  opinions,
accountant's  letters and other documents as Valley shall reasonably request and
as are customarily provided in connection with registrations of securities under
the  Securities Act of 1933, as amended.  All expenses  incurred by Merchants in
complying with the provisions of this Section 4, including  without  limitation,
all registration and filing fees,  printing expenses,  fees and disbursements of
counsel for Merchants and blue sky fees and expenses shall be paid by Merchants.
Underwriting  discounts and  commissions to brokers and dealers  relating to the
Option or Option  Shares,  fees and  disbursements  of counsel to Valley and any
other expenses incurred by Valley in connection with such registration  shall be
borne by Valley.  In connection with such filing,  Merchants shall indemnify and
hold harmless Valley against any losses, claims,  damages or liabilities,  joint
or several, to which Valley may become subject,  insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue  statement or alleged  untrue  statement  of any  material  fact
contained in any preliminary or final registration statement or any amendment or
supplement  thereto,  or arise  out of a  material  fact  required  to be stated
therein  or  necessary  to make  the  statements  therein  not  misleading;  and
Merchants  will  reimburse  Valley  for any  legal or other  expense  reasonably
incurred by Valley in connection with  investigating or defending any such loss,
claim, damage, liability or action;  provided,  however, that Merchants will not
be  liable  in any case to the  extent  that any such  loss,  claim,  damage  or
liability  arises out of or is based upon an untrue  statement or alleged untrue
statement  or omission or alleged  omission  made in such  preliminary  or final
registration  statement or such amendment or supplement thereto in reliance upon
and in conformity with written  information  furnished by or on behalf of Valley
specifically  for use in the  preparation  thereof with  respect to  information
about  the  selling  stockholders  or the  plan  of  distribution.  Valley  will
indemnify  and hold  harmless  Merchants  to the same extent as set forth in the
immediately  preceding  sentence but only with reference to written  information
specifically  furnished by or on behalf of Valley for use in the  preparation of
such preliminary or final registration statement or such amendment or supplement
thereto with respect to information  about the selling  stockholders or the plan
of  distribution;  and Valley will  reimburse  Merchants  for any legal or other
expense  reasonably  incurred by Merchants in connection with  investigating  or
defending any such loss,  claim,  damage,  liability or action.  Notwithstanding
anything to the contrary herein,  no indemnifying  party shall be liable for any
settlement effected without its prior written consent.

5.                Adjustments.

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

                  In the event any capital reorganization or reclassification of
the  Common  Stock,  or any  consolidation,  merger or  similar  transaction  of
Merchants with another entity,  or any sale of all or  substantially  all of the
assets of Merchants,  shall be effected in such a way that the holders of Common
Stock shall be entitled to receive  stock,  securities or assets with respect to
or in exchange for Common Stock,  then,  as a condition of such  reorganization,
reclassification,  consolidation, merger or sale, lawful and adequate provisions
(in form reasonably satisfactory to the holder hereof) shall be made whereby the
holder hereof shall  thereafter  have the right to purchase and receive upon the
basis and upon the  terms and  conditions  specified  herein  and in lieu of the
Common Stock immediately theretofore purchasable and receivable upon exercise of
the rights  represented  by this  Option,  such shares of stock,  securities  or
assets as may be issued or payable with respect to or in exchange for the number
of shares of Common Stock  immediately  theretofore  purchasable  and receivable
upon exercise of the rights represented by this Option had such  reorganization,
reclassification,  consolidation,  merger  or sale not  taken  place;  provided,
however,  that if such  transaction  results  in the  holders  of  Common  Stock
receiving only cash, the holder hereof shall be paid the difference  between the
Option  Price and such  cash  consideration  without  the need to  exercise  the
Option.

                  b. Adjustments  Based Upon Changes in Market Price. If, on the
date of the first  occurrence  of any  Triggering  Event  under  Section  2, the
Average Merger Consideration  Equivalent is less than the Option Price, then the
Option  Price  automatically  shall be reduced  to the amount of the  Discounted
Average  Merger   Consideration   Equivalent.   As  used  herein,   the  "Merger
Consideration  Equivalent"  on any trading day means the Closing Price of Valley
Common Stock on such day multiplied by the Exchange Ratio (with "Closing Price,"
"Valley Common Stock" and "Exchange  Ratio" all having the meanings  assigned to
them in the Merger  Agreement).  The "Average Merger  Consideration  Equivalent"
means the average of the Merger Consideration Equivalents during the Measurement
Period.  The  "Discounted  Average Merger  Consideration  Equivalent"  means the
Average Merger  Consideration  Equivalent minus $3.06. The "Measurement  Period"
shall be determined  as follows:  (a) If there is at least one but less than ten
trading  days  between  the  date of the  Merger  Agreement  and the date of the
Triggering Event (calculated in this paragraph by excluding both the date of the
Merger  Agreement and the date of the Triggering  Event),  then the "Measurement
Period" is the entire  period  between the date of the Merger  Agreement and the
date of the Triggering Event. (b) If there are at least ten but not more than 60
trading  days  between  the  date of the  Merger  Agreement  and the date of the
Triggering Event, then the "Measurement  Period" is the ten consecutive  trading
day period falling between the date of the Merger  Agreement and the date of the
Triggering  Event  which  produces  the  lowest  Average  Merger   Consideration
Equivalent.  (c) If there are more than 60 trading  days between the date of the
Merger  Agreement and the date of the Triggering  Event,  then the  "Measurement
Period" is the ten consecutive  trading day period falling during the 60 trading
day period ending with the last trading day prior to the date of the  Triggering
Event which produces the lowest Average Merger Consideration  Equivalent. If the
Exchange Ratio is adjusted during or after the Measurement  Period,  the Average
Merger Consideration Equivalent shall be calculated or adjusted appropriately to
reflect the adjustment in the Exchange Ratio.

6. Filings and Consents.  Each of Valley and Merchants  will use its  reasonable
efforts to make all filings with,  and to obtain  consents of, all third parties
and governmental  authorities  necessary to the consummation of the transactions
contemplated by this Agreement.

                  Exercise  of the Option  herein  provided  shall be subject to
compliance with all applicable laws including,  but not limited to, in the event
Valley is the holder  hereof,  approval of the Board of Governors of the Federal
Reserve  System,  the  Federal  Deposit  Insurance  Corporation,  the  New  York
Department of Banking or the Securities and Exchange  Commission,  and Merchants
agrees to cooperate with and furnish to the holder hereof such  information  and
documents as may be reasonably required to secure such approvals.

7. Representations and Warranties of Merchants.  Merchants hereby represents and
warrants to Valley as follows:

a. Due  Authorization.  Merchants  has full  corporate  power and  authority  to
execute,  deliver and perform this Agreement and all corporate  action necessary
for execution, delivery and performance of this Agreement has been duly taken by
Merchants.

b.  Authorized  Shares.  Merchants  has  taken  and,  as long as the  Option  is
outstanding,  will take all necessary  corporate action to authorize and reserve
for  issuance  all  shares of Common  Stock that may be issued  pursuant  to any
exercise of the Option.

c. No  Conflicts.  Neither the  execution  and  delivery of this  Agreement  nor
consummation of the transactions  contemplated  hereby (assuming all appropriate
regulatory  approvals)  will violate or result in any violation or default of or
be in conflict with or constitute a default under any term of the Certificate of
Incorporation  or Bylaws of Merchants or any  agreement,  instrument,  judgment,
decree or order applicable to Merchants.

8. Specific Performance. The parties hereto acknowledge that damages would be an
inadequate remedy for a breach of this Agreement and that the obligations of the
parties hereto shall be specifically enforceable. Notwithstanding the foregoing,
Valley shall have the right to seek money damages against Merchants for a breach
of this Agreement.

9. Entire Agreement. This Agreement constitutes the entire agreement between the
parties with respect to the subject matter hereof and supersedes all other prior
agreements and  understandings,  both written and oral, among the parties or any
of them with respect to the subject matter hereof.

10. Assignment or Transfer.  Valley may not sell,  assign or otherwise  transfer
its  rights and  obligations  hereunder,  in whole or in part,  to any person or
group of persons other than to an affiliate of Valley, until the occurrence of a
Triggering Event. Valley represents that it is acquiring the Option for Valley's
own  account  and  not  with a view  to or  for  sale  in  connection  with  any
distribution  of the Option or the Option  Shares.  Valley is aware that neither
the Option  nor the Option  Shares is the  subject of a  registration  statement
filed with, and declared  effective by, the  Securities and Exchange  Commission
pursuant to Section 5 of the  Securities  Act, but instead each is being offered
in reliance upon the exemption  from the  registration  requirement  provided by
Section 4(2) thereof and the  representations  and warranties  made by Valley in
connection  therewith.  After the occurrence of a Triggering  Event,  Valley may
sell,  assign,   pledge,  or  otherwise  transfer  its  rights  and  obligations
hereunder,  in whole or in part,  to any  person,  subject  to  compliance  with
applicable law.

11.  Amendment of Agreement.  Upon mutual  consent of the parties  hereto,  this
Agreement may be amended in writing at any time, for the purpose of facilitating
performance  hereunder  or to  comply  with  any  applicable  regulation  of any
governmental  authority  or any  applicable  order of any court or for any other
purpose.

12.  Validity.  The  invalidity  or  unenforceability  of any  provision of this
Agreement  shall  not  affect  the  validity  or  enforceability  of  any  other
provisions of this Agreement, which shall remain in full force and effect.

13. Notices. All notices,  requests,  consents and other communications required
or permitted hereunder shall be in writing and shall be deemed to have been duly
given when delivered personally,  or delivered by overnight delivery service, or
by registered or certified mail (postage prepaid,  return receipt  requested) to
