which are hereby acknowledged, the parties hereto hereby agree as follows:

<PAGE>

I.  Appointment  of Escrow  Agent and  Creation of Account.  The Company  hereby
appoints the Escrow Agent as escrow agent hereunder and directs it to hold those
funds  received  from  subscribers  for Shares which may be  deposited  with the
Escrow  Agent from time to time to be held  pursuant to this  Agreement  and any
income  earned  from  investment  of  such  assets  (collectively,  the  "Escrow
Assets"),  in a  separate  account  in the  name of "SB  Merger  Corp.  - Escrow
Account"  (the  "Escrow  Account").   The  Escrow  Account  shall  be  invested,
administered and distributed in accordance with the terms set forth below.

     1.  Initial  Funding of Escrow  Account;  Return of Funds if  Offering  Not
Completed. The Escrow Account shall be funded with the proceeds from the sale of
Shares by the Company. All funds received by the Company or the Underwriter from
the sale of Shares by the  Company  shall be  deposited  directly  in the Escrow
Account by wire transfer, check or money order. In the event funds aggregating a
total  of  $125,000  are not  deposited  into  the  Escrow  Account  by the time
specified in the Registration  Statement (the  "Termination  Date"),  the Escrow
Agent will return the funds to subscribers,  without  interest.  In the event an
aggregate  of  $125,000  is  deposited  in the  Escrow  Account on or before the
Termination  Date,  the Escrow Agent shall retain the Escrow  Assets  during the
ensuing period (the "Post-Offering  Period") pending  distribution in accordance
with Section 3 below.

     2. Investment of Escrow Assets. The Escrow Assets shall be invested,  if at
all, in accordance with the instructions set forth in Exhibit A attached hereto.
Such instructions may be modified only by a written  certificate  executed by an
authorized  officer of the Company and delivered to the Escrow  Agent;  however,
this  Escrow  Agreement  may not be  altered  by the Board of  Directors  of the
Company in terms of the  investment  instructions,  except as may be required by
the Board of Directors to fulfill their fiduciary obligations.  The Escrow Agent
shall make  monthly  accounting  of any such  investments,  the income  received
therefrom, and the then existing balance of the Escrow Account to the Company.

     3. Post-Offering  Period Distribution from Escrow Account. The Escrow Agent
shall make distributions from the Escrow Account during the Post-Offering Period
in accordance with the requirements set forth in Exhibit B attached hereto. Such
instructions  may  be  modified  only  by  a  written  certificate  executed  by
authorized  officers of the  Company,  and  delivered  to the Escrow  Agent.  In
addition,  this Escrow Agreement may not be altered by the Board of Directors of
the Company in terms of its distribution instructions, except as may be required
by the Board of Directors to fulfill  their  fiduciary  obligations.  The Escrow
Agent is authorized to make  distributions  in reliance on the  instructions  it
receives.  Written  notice of each  disbursement  from the Escrow Agent shall be
provided to the Company within ten (10) days of each such disbursement. Upon the
final  distribution of all of the Escrow Assets,  this Agreement shall terminate
and the Escrow Agent shall have no further obligations or liabilities hereunder.

     4.  Compensation  of Escrow  Agent.  The Escrow  Agent shall  receive  fees
determined in accordance with, and payable as specified in, the Schedule of Fees
attached hereto as Exhibit C (the "Fee  Schedule").  The Escrow Agent shall have
no duties or liabilities  under this Agreement  unless and until full payment of
the fee set forth in Exhibit  C. The Escrow  Agent  shall be  reimbursed  by

                                      -2-
<PAGE>

the Company for all expenses, disbursements and advances incurred or made by the
Escrow Agent in preparation,  administration  and enforcement of this Agreement,
including,  but not limited to, reasonable legal fees and expenses.  The Company
shall be liable for all payments due to the Escrow Agent under this Agreement.

     5.  Responsibilities  and Rights of the Escrow Agent.  To induce the Escrow
Agent to act hereunder, it is further agreed by the undersigned that:

          (a) The Escrow  Agent  undertakes  to perform  only such duties as are
     expressly  set  forth  herein.  Without  limiting  the  generality  of  the
     foregoing, the Escrow Agent shall have no duty or responsibility as regards
     any:  (i)  security  as to which a default in the payment of  principal  or
     interest has occurred,  to give notice of default,  make demand for payment
     or take any  other  action  with  respect  to such  default;  and (ii) loss
     occasioned  by  delay in the  actual  receipt  of  notice  of any  payment,
     redemption or other transaction  regarding any item in the Escrow Assets as
     to which it is  authorized to take action  hereunder.  The Escrow Agent may
     consult  with  counsel  and shall be fully  protected  with  respect to any
     action taken in good faith in accordance with such advice. The Escrow Agent
     shall have no  liability  or  responsibility  for any  misstatement  in, or
     omission from, the Prospectus.

          (b) The  Escrow  Agent  shall not be under any duty to give the Escrow
     Assets held by it  hereunder  any greater  degree of care than it gives its
     own  similar  property  and shall not be  required to invest any funds held
     hereunder  except as directed  pursuant to this  Escrow  Agreement.  In the
     event that there is a change in the  investment  instructions  resulting in
     uninvested  funds,  such uninvested  funds held hereunder shall not earn or
     accrue interest.

          (c) The Escrow Agent does not make any representation or warranty with
     regard to the creation or perfection, hereunder or otherwise, of a security
     interest  in  the  Escrow   Assets  or  regarding  the   negotiability   or
     transferability  of, or existence of other  interests in the Escrow Assets.
     The Escrow  Agent  shall have no  responsibility  at any time to  ascertain
     whether or not any  security  interest  exists in the Escrow  Assets or any
     part  thereof  or  to  file  any  financing  statement  under  the  Uniform
     Commercial  Code of any state with respect to the Escrow Assets or any part
     thereof.

          (d) The Escrow Agent is hereby  authorized to comply with any judicial
     order or legal process which stays,  enjoins,  directs or otherwise affects
     the transfer or delivery of the Escrow Assets or any party hereto and shall
     incur no  liability  for any  delay or loss  which may occur as a result of
     such compliance.

          (e) The Escrow Agent shall have no duty or responsibility  with regard
     to  any  loss  resulting  from  the  investment,   reinvestment,   sale  or
     liquidation  of the  Escrow  Assets  in  accordance  with the terms of this
     Agreement. The Escrow Agent need not maintain any insurance with respect to
     the Escrow Assets.

          (f) The Escrow  Agent shall in no event be liable in  connection  with
     its  investment  or  reinvestment  of any cash held by it hereunder in good
     faith, in accordance with the terms hereof, including,  without limitation,
     any liability for any delays (not resulting from its gross

                                      -3-
<PAGE>

     negligence or willful  misconduct) in the investment or reinvestment of the
     Escrow Assets, or any loss of interest incident to any such delays.

          (g) Except as otherwise expressly provided herein, the Escrow Agent is
     authorized to execute  instructions and take other actions pursuant to this
     Agreement in accordance with its customary processing practices for similar
     customers  and, in  accordance  with such  practices  the Escrow  Agent may
     retain agents,  including its own  subsidiaries  or affiliates,  to perform
     certain of such  functions.  The Escrow Agent shall have no liability under
     this  Agreement for any loss or expense other than those  occasioned by the
     Escrow Agent's gross negligence or willful  misconduct and in any event its
     liability  shall be limited to direct  damages  and shall not  include  any
     special or  consequential  damages.  All collection and receipt of funds or
     securities  and all payment and delivery of funds or securities  under this
     Agreement  shall be made by the Escrow  Agent as agent,  at the risk of the
     other  parties  hereto with respect to their actions or omissions and those
     of any person  other than the Escrow  Agent.  In no event  shall the Escrow
     Agent be  responsible  or  liable  for any loss  due to  force  beyond  its
     control,  including,  but not limited to, acts of God, flood, fire, nuclear
     fusion,  fission or  radiation,  war (declared or  undeclared),  terrorism,
     insurrection,  revolution,  riot, strikes or work stoppages for any reason,
     embargo, government action, including any laws, ordinances,  regulations or
     the  like  which  restrict  or  prohibit  the  providing  of  the  services
     contemplated   by  this  Agreement,   inability  to  obtain   equipment  or
     communications  facilities,  or the failure of equipment or interruption of
     communications  facilities,  and other  causes  whether  or not of the same
     class or kind as  specifically  named  above.  In the event that the Escrow
     Agent is unable  substantially to perform for any of the reasons  described
     in the immediately preceding sentence, it shall so notify the other parties
     hereto as soon as reasonably  practicable following its actual knowledge of
     the same.

          (h) This Escrow  Agreement  expressly sets forth all the duties of the
     Escrow  Agent with  respect to any and all  matters  pertinent  hereto.  No
     implied duties or obligations shall be read into this agreement against the
     Escrow  Agent.  Notwithstanding  any  provisions  of this  Agreement to the
     contrary,   the  Escrow   Agent   shall  not  be  bound  by,  or  have  any
     responsibility  with respect to, any other  agreement or contract among the
     Company  and the  Representatives  (whether  or not the  Escrow  Agent  has
     knowledge thereof).

          (i) It is  understood  and agreed that  should any dispute  arise with
     respect to the  payment  and/or  ownership  or right of  possession  of the
     Escrow  Assets,  or should the Escrow Agent in good faith be in doubt as to
     what action it should take  hereunder,  the Escrow Agent is authorized  and
     directed to retain in its possession,  without liability to anyone,  all or
     any part of the Escrow  Assets until such  dispute  shall have been settled
     either by mutual agreement by the parties  concerned or by the final order,
     decree or judgment of any court or other tribunal of competent jurisdiction
     in the United  States of America  and time for  appeal has  expired  and no
     appeal  has been  perfected,  but the Escrow  Agent  shall be under no duty
     whatsoever  to  institute  or defend any such  proceedings.  Any such court
     order shall be accompanied by a legal opinion by counsel for the presenting
     party  satisfactory to the Escrow Agent to the effect that said court order
     is final and non-appealable.

          (j) The  Escrow  Agent  shall be  entitled  to rely  upon  any  order,
     judgment,  certification,  demand,  notice,  instrument  or  other  writing
     delivered  to  it  hereunder   without  being  required  to  determine  the
     authenticity or the correctness of any fact stated therein or the propriety
     or validity of the service thereof.  Without limiting the foregoing, in the
     event of any alteration of

                                      -4-
<PAGE>

     investment  or  distribution  instructions,  the Escrow Agent shall have no
     responsibility to determine  whether the requested  alteration was required
     by the  Board  of  Directors  of  the  Company  to  fulfill  its  fiduciary
     obligations.  The Escrow Agent may act in reliance  upon any  instrument or
     signature  believed  by it to be  genuine  and may  assume  that any person
     purporting  to give receipt or advice or make any  statement or execute any
     document in connection with the provisions  hereof has been duly authorized
     to do so.

          (k) The Company  shall hold the Escrow  Agent and its agents  harmless
     from,  and  indemnify and reimburse the Escrow Agent and its agents for all
     claims, liability, loss and expense (including reasonable out-of-pocket and
     incidental  expenses and legal fees),  incurred by the Escrow Agent or them
     in connection  with the Escrow Agent or their acting under this  Agreement,
     provided  that the Escrow Agent or they, as the case may be, have not acted
     with gross  negligence  or willful  misconduct  with  respect to the events
     resulting in such claims, liability, loss, and expense.

          (l) The  Company  acknowledges  and agree  that,  except as  otherwise
     provided in this Section  5(l),  the Escrow Agent shall not be  responsible
     for taking any steps, including without limitation,  the filing of forms or
     reports,  or  withholding  of  any  amounts  in  connection  with  any  tax
     obligations of the Company or any other party in connection with the Escrow
     Assets; provided,  however, that the Escrow Agent shall be entitled to take
     any  action  such as  withholding,  that it  deems  appropriate  to  ensure
     compliance with its obligations  under any applicable tax laws. In no event
     shall the Escrow  Agent be  required  to  distribute  funds from the Escrow
     Account to either the  shareholders  or the Company unless the  appropriate
     Internal  Revenue Service Form W-8 or Form W-9 are received,  if necessary.
     Notwithstanding   the   foregoing,   the  Escrow  Agent  shall  supply  any
     information  or documents as may be reasonably  requested by the Company in
     connection with the Company's preparation of its tax returns for the Escrow
     Account.  Upon any  distribution  of Escrow Assets in  accordance  with the
     instructions set forth in Exhibit B attached hereto, the Escrow Agent shall
     prepare  and deliver to each person  receiving a  distribution  a completed
     Form 1099, if necessary,  and shall supply any necessary information as may
     reasonably be requested in writing by such persons.

          (m) The Escrow Agent does not have any  interest in the Escrow  Assets
     deposited  hereunder  but is serving as escrow  holder only and having only
     possession  thereof.  The Company  shall pay or reimburse  the Escrow Agent
     upon request for any transfer  taxes or other taxes  relating to the Escrow
     Assets  incurred  in  connection  herewith  and  shall  indemnify  and hold
     harmless  the Escrow  Agent from any amounts that it is obligated to pay in
     the way of such taxes.  This paragraph  shall survive  notwithstanding  any
     termination  of this  Escrow  Agreement  or the  resignation  of the Escrow
     Agent.

          (n) The  Escrow  Agent  makes no  representation  as to the  validity,
     value,  genuineness or the collectability of any security or other document
     or instrument held by or delivered to it.

          (o) The Escrow  Agent  shall not be called upon to advise any party as
     to the wisdom in  selling or  retaining  or taking or  refraining  from any
     action  with  respect  to  any  securities  or  other  property   deposited
     hereunder.

                                      -5-
<PAGE>

          (p) No  printed or other  matter in any  language  (including  without
     limitation  prospectuses,  notices, reports and promotional material) which
     mentions  the Bank's  name or the rights,  powers,  or duties of the Escrow
     Agent  shall be  issued  by the other  parties  hereto or on such  parties,
     behalf unless the Escrow Agent shall first have given its specific  written
     consent thereto.  Notwithstanding the foregoing sentence,  the Escrow Agent
     hereby  specifically  consents  to the use of its name as  Escrow  Agent as
     necessary  to  effectuate  the  Company's  public  offering  and a business
     combination of the Company.

          (q) The Company  authorizes the Escrow Agent,  for any securities held
     hereunder,  to use the  services of any United  States  central  securities
     depository  it  deems  appropriate,  including,  but not  limited  to,  the
     Depositary Trust Company and the Federal Reserve Book Entry System.

     6. Instructions: Fund Transfers.

          (a)  The  Escrow  Agent  is  authorized  to  rely  and  act  upon  all
     instructions  given  or  purported  to be  given  by one or more  officers,
     employees or agents of the Company (i) authorized by or in accordance  with
     a corporate  resolution  delivered to the Escrow Agent or (ii) described as
     authorized  in  a  certificate   delivered  to  the  Escrow  Agent  by  the
     appropriate  Secretary or Assistant Secretary or similar officer (each such
     officer, employee or agent or combination of officers, employees and agents
     authorized  pursuant to clause (i) or described  pursuant to clause (ii) of
     this Section 6(a) is hereinafter  referred to as an "Authorized  Officer").
     (The term  "instructions"  includes,  without  limitation,  instructions to
     sell, assign, transfer, deliver, purchase or receive for the Escrow Account
     any and all stocks,  bonds and other  securities  or to transfer all or any
     portion of the Escrow  Assets.) The Escrow Agent may also rely and act upon
     instructions  when bearing or purporting to bear the signature or facsimile
     signature of any of the  individuals  designated by an  Authorized  Officer
     regardless  of by whom or by what means the actual or  purported  facsimile
     signature  or  signatures  thereon  may have been  affixed  thereto if such
     facsimile  signature  or  signatures  resemble  the  facsimile  specimen or
     specimens  from time to time  furnished  to the Escrow Agent by any of such
     Authorized  Officers,  Secretary  or  an  Assistant  Secretary  or  similar
     officer).  In addition,  and subject to subsection 6(b) hereof,  the Escrow
     Agent may rely and act upon instructions received by telephone,  telex, TXW
     facsimile  transmission,  bank wire or other  teleprocess  acceptable to it
     which the  Escrow  Agent  believes  in good  faith to have been given by an
     Authorized  Officer  or  which  are  transmitted  with  proper  testing  or
     authentication  pursuant to terms and conditions which the Escrow Agent may
     specify.  The Escrow  Agent  shall  incur no  liability  to the  Company or
     otherwise for having acted in accordance  with  instructions on which it is
     authorized  to rely pursuant to the  provisions  hereof.  Any  instructions
     delivered to the Escrow Agent by telephone  shall  promptly  thereafter  be
     confirmed  in writing by an  Authorized  Officer but the Escrow Agent shall
     incur no liability for a failure to send such confirmation in writing,  the
     failure  of any such  written  confirmation  to  conform  to the  telephone
     instruction which it received, the failure of any such written confirmation
     to  be  signed  or  properly  signed,   or  its  failure  to  produce  such
     confirmation  at any  subsequent  time.  The Escrow  Agent  shall  incur no
     liability for refraining from acting upon any  instructions,  which for any
     reason  it, in good  faith,  is  unable to verify to its own  satisfaction.
     Unless otherwise  expressly  provided,  all authorizations and instructions
     shall  continue in full force and effect until  canceled or  superseded  by
     subsequent  authorizations  or instructions  received by the Escrow Agent's
     safekeeping account administrator. The Escrow Agent's authorization to rely
     and

                                      -6-
<PAGE>

     act upon  instructions  pursuant to this paragraph shall be in addition to,
     and shall not limit, any other authorization, which the Company may give to
     it hereunder.

          (b) With respect to written or telephonic instructions or instructions
     sent by facsimile transmission to transfer funds from the Escrow Account in
     accordance herewith (such instructions hereinafter referred to as "Transfer
     Instructions"),  the  security  procedure  agreed  upon for  verifying  the
     authenticity of Transfer  Instructions is a callback by the Escrow Agent to
     any of the  persons  designated  below,  whether or not any such person has
     issued  such  Transfer  Instruction.  (It is  recommended  that the persons
     designated below not be persons who generally issue Transfer  Instructions;
     whenever  possible,  the Escrow Agent will  endeavor to call someone  other
     than the issuer of the Transfer Instructions).

     With respect to Transfer  Instructions given by the Company pursuant to its
authority under this Agreement:

             Name/Title                                     Telephone No.
             ----------                                     -------------

             Judith Haselton, President                     (212) 678-6231

             Richard L. Campbell, Secretary                 (810) 220-1220

     Alternatively,  at the Escrow Agent's  option,  the callback may be made to
any person  designated in the certified  resolutions  or other  certificates  or
documentation  furnished to it by a party in connection  with the Escrow Account
as authorized to issue Transfer Instructions or otherwise transact business with
respect to the Escrow  Account for that party.  The Company shall  implement any
other  authentication  method or  procedure or security  device  required by the
Escrow Agent at any time or from time to time.

     7. Stockholder Redemption.  In the event a stockholder exercises his or her
redemption right upon a business  combination of the Company, the funds to repay
said stockholder shall be distributed  directly from the Escrow Account. As soon
as practicable  after the Company  receives  notice from a stockholder  that the
stockholder is exercising its redemption  rights, the Company shall instruct the
Escrow  Agent to  transfer,  and (so long as the Escrow  Agent has  received any
necessary  Internal Revenue Service Form W-8 or Form W-9) the Escrow Agent shall
so transfer the funds owed to the stockholder;  such instructions to include the
amount to be transferred and delivery  instructions.  These  instructions  shall
comply with Section 6 of this Escrow Agreement.

     8. Resignation or Removal of Escrow Agent.

          (a) The Escrow Agent may resign at any time by giving  written  notice
     to the Company. The Company may remove the Escrow Agent upon written notice
     to the Escrow  Agent.  Such  resignation  or removal shall take effect upon
     delivery of the Escrow  Assets to a successor  escrow agent  designated  in
     writing by the Company,  and the Escrow Agent shall thereupon be discharged
     from all obligations under this Agreement, and shall have no further duties
     or responsibilities in connection herewith.  The obligations of the Company
     to the Escrow Agent and the rights of the Escrow Agent under Sections 4 and
     5(k) hereof shall survive  termination of this Agreement or the resignation
     or removal of the Escrow Agent.

                                      -7-
<PAGE>

          (b)  In  the  event  that  the  Escrow  Agent   submits  a  notice  of
     resignation,  its only duty, until a successor Escrow Agent shall have been
     appointed and shall have accepted  such  appointment,  shall be to safekeep
     the Escrow  Assets,  and hold,  invest and dispose of the Escrow  Assets in
     accordance with this Agreement, until receipt of a designation of successor
     Escrow Agent or a joint written disposition instrument by the other parties
     hereto or a Final Order of a court of competent  jurisdiction,  but without
     regard to any notices, requests, instructions, demands or the like received
     by it from the other  parties  hereto  after  such  notice  shall have been
     given,  unless the same is a  direction  that the Escrow  Assets be paid or
     delivered in its entirety out of the Escrow Account. The Escrow Agent, upon
     submission of its resignation in accordance with this  subparagraph (b) may
     deposit the Escrow  Assets with a court of  competent  jurisdiction  if the
     Escrow Agent deems such action  advisable.  The  resignation  of the Escrow
     Agent will take effect on the earlier of (a) the appointment of a successor

     3. Compensation of Escrow Agent. The Escrow Agent shall receive fees

Company for all expenses, disbursements and advances incurred or made by the
Escrow Agent in preparation, administration and enforcement of this Agreement,
including, but not limited to, reasonable legal fees and expenses. The Company
shall be liable for all payments due to the Escrow Agent under this Agreement.

     4. Responsibilities and Rights of the Escrow Agent. To induce the Escrow
Agent to act hereunder, it is further agreed by the undersigned that:

          (a) The Escrow  Agent  undertakes  to perform  only such duties as are
     expressly  set  forth  herein.  Without  limiting  the  generality  of  the
     foregoing, the Escrow Agent shall have no duty or responsibility as regards
     any loss  occasioned  by delay  in the  actual  receipt  of  notice  of any
     payment,  redemption or other transaction  regarding any item in the Escrow
     Assets as to which it is  authorized to take action  hereunder.  The Escrow
     Agent may consult with counsel and shall be fully protected with respect to
     any action taken in good faith in accordance  with such advice.  The Escrow
     Agent shall have no liability or responsibility for any misstatement in, or
     omission from, the Prospectus.

          (b) The Escrow  Agent shall not be under any duty to give the Escrowed
     Assets held by it  hereunder  any greater  degree of care than it gives its
     own similar property except as directed pursuant to this Escrow Agreement.

          (c) The Escrow Agent does not make any representation or warranty with
     regard to the creation or perfection, hereunder or otherwise, of a security
     interest  in  the  Escrow   Assets  or  regarding  the   negotiability   or
     transferability  of, or existence of other  interests in the Escrow Assets.
     The Escrow  Agent  shall have no  responsibility  at any time to  ascertain
     whether or not any  security  interest  exists in the Escrow  Assets or any
     part  thereof  or  to  file  any  financing  statement  under  the  Uniform
     Commercial  Code of any state with respect to the Escrow Assets or any part
     thereof.

          (d) The Escrow Agent is hereby  authorized to comply with any judicial
     order or legal process which stays,

                                       3
<PAGE>

     enjoins,  directs or  otherwise  affects  the  transfer  or delivery of the
     Escrow  Assets or any party  hereto and shall  incur no  liability  for any
     delay or loss which may occur as a result of such compliance.

          (e) The Escrow Agent need not maintain any  insurance  with respect to
     the Escrow Assets.

          (f) Except as otherwise expressly provided herein, the Escrow Agent is
     authorized to execute  instructions and take other actions pursuant to this
     Agreement in accordance with its customary processing practices for similar
     customers  and, in  accordance  with such  practices  the Escrow  Agent may
     retain agents,  including its own  subsidiaries  or affiliates,  to perform
     certain of such  functions.  The Escrow Agent shall have no liability under
     this  Agreement for any loss or expense other than those  occasioned by the
     Escrow Agent's gross negligence or willful  misconduct and in any event its
     liability  shall be limited to direct  damages  and shall not  include  any
     special or consequential  damages. All collection and receipt of securities
     and all delivery of securities  under this  Agreement  shall be made by the
     Escrow Agent as agent, at the risk of the other parties hereto with respect
     to their actions or omissions and those of any person other than the Escrow
     Agent.  In no event shall the Escrow Agent be responsible or liable for any
     loss due to force beyond its control,  including,  but not limited to, acts
     of God, flood, fire, nuclear fusion, fission or radiation, war (declared or
     undeclared),  terrorism,  insurrection,  revolution,  riot, strikes or work
     stoppages for any reason, embargo,  government action,  including any laws,
     ordinances,  regulations  or  the  like  which  restrict  or  prohibit  the
     providing  of the services  contemplated  by this  Agreement,  inability to
     obtain equipment or communications  facilities, or the failure of equipment
     or interruption of communications  facilities,  and other causes whether or
     not of the same class or kind as  specifically  named  above.  In the event
     that the Escrow  Agent is unable  substantially  to perform  for any of the
     reasons described in the immediately preceding sentence, it shall so notify
     the other parties  hereto as soon as reasonably  practicable  following its
     actual knowledge of the same.

          (g) This Escrow  Agreement  expressly sets forth all the duties of the
     Escrow  Agent with  respect to any and all  matters  pertinent  hereto.  No
     implied duties or obligations shall be read into this agreement against the
     Escrow  Agent.  Notwithstanding  any  provisions  of this  Agreement to the
     contrary, the Escrow Agent shall not be bound by, or have any

                                       4
<PAGE>

     responsibility  with respect to, any other  agreement or contract among the
     Company  and the  Representatives  (whether  or not the  Escrow  Agent  has
     knowledge thereof).

          (h) It is  understood  and agreed that  should any dispute  arise with
     respect to the  payment  and/or  ownership  or right of  possession  of the
     Escrow  Assets,  or should the Escrow Agent in good faith be in doubt as to
     what action it should take  hereunder,  the Escrow Agent is authorized  and
     directed to retain in its possession,  without liability to anyone,  all or
     any part of the Escrow  Assets until such  dispute  shall have been settled
     either by mutual agreement by the parties  concerned or by the final order,
     decree or judgment of any court or other tribunal of competent jurisdiction
     in the United  States of America  and time for  appeal has  expired  and no
     appeal  has been  perfected,  but the Escrow  Agent  shall be under no duty
     whatsoever  to  institute  or defend any such  proceedings.  Any such court
     order shall be accompanied by a legal opinion by counsel for the presenting
     party  satisfactory to the Escrow Agent to the effect that said court order
     is final and nonappealable.

          (i) The  Escrow  Agent  shall be  entitled  to rely  upon  any  order,
     judgment,  certification,  demand,  notice,  instrument  or  other  writing
     delivered  to  it  hereunder   without  being  required  to  determine  the
     authenticity or the correctness of any fact stated therein or the propriety
     or validity of the service thereof.  Without limiting the foregoing, in the
     event of any  alteration  of  distribution  instructions,  the Escrow Agent
     shall have no responsibility to determine whether the requested  alteration
     was  required  by the Board of  Directors  of the  Company to  fulfill  its
     fiduciary  obligations.  The  Escrow  Agent  may act in  reliance  upon any
     instrument  or  signature  believed by it to be genuine and may assume that
     any person  purporting  to give receipt or advice or make any  statement or
     execute any document in connection with the provisions hereof has been duly
     authorized to do so.

          (j) The Company  shall hold the Escrow  Agent and its agents  harmless
     from,  and  indemnify and reimburse the Escrow Agent and its agents for all
     claims, liability, loss and expense (including reasonable out-of-pocket and
     incidental  expenses and legal fees),  incurred by the Escrow Agent or them
     in connection  with the Escrow Agent or their acting under this  Agreement,
     provided  that the Escrow Agent or they, as the case may be, have not acted
     with gross  negligence  or willful  misconduct  with  respect to the events
     resulting in such claims, liability, loss, and expense.

                                       5
<PAGE>

          (k) The  Company  acknowledges  and agree  that,  except as  otherwise
     provided in this Section  4(k),  the Escrow Agent shall not be  responsible
     for taking any steps, including without limitation,  the filing of forms or
     reports,  or  withholding  of  any  amounts  in  connection  with  any  tax
     obligations of the Company or any other party in connection with the Escrow
     Assets; provided,  however, that the Escrow Agent shall be entitled to take
     any  action  such as  withholding,  that it  deems  appropriate  to  ensure
     compliance with its obligations under any applicable tax laws.

          (l) The Escrow Agent does not have any  interest in the Escrow  Assets
     deposited  hereunder  but is serving as escrow  holder only and having only
     possession  thereof.  The Company  shall pay or reimburse  the Escrow Agent
     upon request for any transfer  taxes or other taxes  relating to the Escrow
     Assets  incurred  in  connection  herewith  and  shall  indemnify  and hold
     harmless  the Escrow  Agent from any amounts that it is obligated to pay in
     the way of such taxes.  This paragraph  shall survive  notwithstanding  any
     termination  of this  Escrow  Agreement  or the  resignation  of the Escrow
     Agent.

          (m) The  Escrow  Agent  makes no  representation  as to the  validity,
     value,  genuineness or the collectability of any security or other document
     or instrument held by or delivered to it.

          (n) The Escrow  Agent  shall not be called upon to advise any party as
     to the wisdom in  selling or  retaining  or taking or  refraining  from any
     action  with  respect  to  any  securities  or  other  property   deposited
     hereunder.

          (o) No  printed or other  matter in any  language  (including  without
     limitation  prospectuses,  notices, reports and promotional material) which
     mentions the Escrow  Agent's name or the rights,  powers,  or duties of the
     Escrow  Agent  shall be  issued  by the  other  parties  hereto  or on such
     parties, behalf unless the Escrow Agent shall first have given its specific
     written consent thereto. Notwithstanding the foregoing sentence, the Escrow
     Agent hereby  specifically  consents to the use of its name as Escrow Agent

     5. Instructions: Fund Transfers.

          (a)  The  Escrow  Agent  is  authorized  to  rely  and  act  upon  all
     instructions  given  or  purported  to be  given  by one or more  officers,
     employees or agents of the Company (i) authorized by or in accordance  with
     a corporate  resolution  delivered to the Escrow Agent or (ii) described as
     authorized  in  a  certificate   delivered  to  the  Escrow  Agent  by  the
     appropriate  Secretary or Assistant Secretary or similar officer (each such
     officer, employee or agent or combination of officers, employees and agents
     authorized  pursuant to clause (i) or described  pursuant to clause (ii) of
     this Section 5(a) is hereinafter  referred to as an "Authorized  Officer").
     (The term  "instructions"  includes,  without  limitation,  instructions to
     sell, assign, transfer, deliver, purchase or receive for the Escrow Account
     any and all stocks,  bonds and other  securities  or to transfer all or any
     portion of the Escrow  Assets.) The Escrow Agent may also rely and act upon
     instructions  when bearing or purporting to bear the signature or facsimile
     signature of any of the  individuals  designated by an  Authorized  Officer
     regardless  of by whom or by what means the actual or  purported  facsimile
     signature  or  signatures  thereon  may have been  affixed  thereto if such
     facsimile  signature  or  signatures  resemble  the  facsimile  specimen or
     specimens  from time to time  furnished  to the Escrow Agent by any of such
     Authorized  Officers,  Secretary  or  an  Assistant  Secretary  or  similar
     officer).  In addition,  and subject to subsection 5(b) hereof,  the Escrow
     Agent may rely and act upon instructions received by telephone,  telex, TXW
     facsimile  transmission,  bank wire or other  teleprocess  acceptable to it
     which the  Escrow  Agent  believes  in good  faith to have been given by an
     Authorized  Officer  or  which  are  transmitted  with  proper  testing  or
     authentication  pursuant to terms and conditions which the Escrow Agent may
     specify.  The Escrow  Agent  shall  incur no  liability  to the  Company or
     otherwise for having acted in accordance  with  instructions on which it is
     authorized  to rely pursuant to the  provisions  hereof.  Any  instructions
     delivered to the Escrow Agent by telephone  shall  promptly  thereafter  be
     confirmed  in writing by an  Authorized  Officer but the Escrow Agent shall
     incur no liability for a failure to send such confirmation in writing,  the
     failure  of any such  written  confirmation  to  conform  to the  telephone
     instruction which it received, the failure of any such written confirmation
     to  be  signed  or  properly  signed,   or  its  failure  to  produce  such
     confirmation  at any  subsequent  time.  The Escrow  Agent  shall  incur no
     liability for refraining  from acting upon any  instructions  which for any
     reason  it, in good  faith,  is  unable to verify to its own  satisfaction.
     Unless otherwise expressly

                                       7
<PAGE>

     provided,  all authorizations and instructions shall continue in full force
     and effect until  canceled or superseded by  subsequent  authorizations  or
     instructions   received   by  the  Escrow   Agent's   safekeeping   account
     administrator.  The  Escrow  Agent's  authorization  to rely  and act  upon
     instructions  pursuant to this paragraph shall be in addition to, and shall
     not  limit,  any  other  authorization  which  the  Company  may give to it
     hereunder.

          (b) With respect to written or telephonic instructions or instructions
     sent by  facsimile  transmission  to  transfer  securities  from the Escrow
     Account in accordance herewith (such instructions  hereinafter  referred to
     as  "Transfer  Instructions"),  the  security  procedure  agreed  upon  for
     verifying the  authenticity  of Transfer  Instructions is a callback by the
     Escrow  Agent to any of the persons  designated  below,  whether or not any
     such person has issued such Transfer  Instruction.  (It is recommended that
     the persons  designated  below not be persons who generally  issue Transfer
     Instructions;  whenever  possible,  the Escrow Agent will  endeavor to call
     someone other than the issuer of the Transfer Instructions).

          With respect to Transfer Instructions given by the Company pursuant to
     its authority under this Agreement:

     Name/Title                              Telephone No.
     ----------                              -------------

     Judith Haselton, President              (212) 678-6231
     Richard L. Campbell,Secretary           (810) 220-1220

          Alternatively,  at the Escrow Agent's option, the callback may be made
     to any person designated in the certified resolutions or other certificates
     or  documentation  furnished to it by a party in connection with the Escrow
     Account as authorized to issue Transfer  Instructions or otherwise transact
     business  with  respect to the Escrow  Account for that party.  The Company
     shall  implement any other  authentication  method or procedure or security
     device required by the Escrow Agent at any time or from time to time.

     6. Stockholder Redemption. In the event a stockholder exercises his or her
redemption right upon a business combination of the Company, following the
return of the funds to said stockholder from the Funds Escrow created of even
date herewith between the Company and the Escorw Agent, the Shares which are the
subject of the redemption shall be cancelled.

     7. Resignation or Removal of Escrow Agent.

          (a) The Escrow Agent may resign at any time by giving  written  notice
     to the Company. The Company may remove the Escrow Agent upon written notice
     to the Escrow  Agent.  Such  resignation  or removal shall take effect upon
     delivery of the Escrow  Assets to a successor  escrow agent  designated  in
     writing by the Company,  and the Escrow Agent shall thereupon be discharged
     from all obligations under this Agreement, and shall have no further duties
     or responsibilities in connection herewith.  The obligations of the Company
     to the Escrow Agent and the rights of the Escrow Agent under Sections 3 and
     4(j) hereof shall survive  termination of this Agreement or the resignation
     or removal of the Escrow Agent.

          (b)  In  the  event  that  the  Escrow  Agent   submits  a  notice  of
     resignation,  its only duty, until a successor Escrow Agent shall have been
     appointed and shall have accepted  such  appointment,  shall be to safekeep
     the Escrow  Assets,  and hold,  invest and dispose of the Escrow  Assets in
     accordance with this Agreement, until receipt of a designation of successor
     Escrow Agent or a joint written disposition instrument by the other parties
     hereto or a Final Order of a court of competent  jurisdiction,  but without
     regard to any notices, requests, instructions, demands or the like received
     by it from the other  parties  hereto  after  such  notice  shall have been
     given,  unless the same is a  direction  that the Escrow  Assets be paid or
     delivered in its entirety out of the Escrow Account. The Escrow Agent, upon
     submission of its resignation in accordance with this  subparagraph (b) may
     deposit the Escrow  Assets with a court of  competent  jurisdiction  if the
     Escrow Agent deems such action  advisable.  The  resignation  of the Escrow
     Agent will take effect on the earlier of (a) the appointment of a successor
     (including  a court of competent  jurisdiction)  or (b) the day which is 30
     days after the date of delivery of its written notice of resignation to the
     other parties  hereto.  If, at the time the Escrow Agent has not received a
     designation  of  a  successor   Escrow  Agent,   the  Escrow  Agent's  sole
     responsibility  after that time  shall be to  safe-keep  the Escrow  Assets
     until  receipt of a  designation  of a  successor  Escrow  Agent or a joint
     written disposition instrument by the other parties hereto or a final order
     of a court of competent jurisdiction.
